Description

Embodiments of the present invention relate to a refrigerator.

Conventionally, in a refrigerator, a buzzer is provided to notify, for example, a warning that the door is not closed and a response to an operation input by a user (see, for example, Patent Document 1). In addition, there are some that give a voice notification such as "the door is not closed" instead of a buzzer sound.

Japanese Unexamined Patent Publication No. 2013-250006

By the way, when the buzzer is used, the information that can be given to the user is limited. In this case, it is considered that detailed information can be notified by performing the notification by voice as described above.

However, for example, in the case of a general refrigerator, there are many warnings that the door is in a half-door state, but when the door is opened to clean the inside of the refrigerator, the warning is repeated that the door is in a half-door state. If this happens, the user may feel annoyed, and the door must be opened and closed each time to stop the warning, which may reduce the usability and maintainability of the refrigerator. On the other hand, it is difficult for the refrigerator to know whether the door is open or simply forgotten to close for cleaning, so it is also necessary to warn that the door is in a half-door state. Is.
Therefore, we provide a refrigerator that can increase the amount of information given to the user and suppress the deterioration of usability and maintainability.

Hereinafter, embodiments will be described with reference to FIGS. 1 to 3.
As shown in FIG. 1, in the refrigerator 1, a plurality of storage chambers having an open front surface are arranged side by side in the vertical direction in the main body 2. In the case of the refrigerator 1 of the present embodiment, the ice making chamber 5 and the small freezing chamber 6 arranged in the main body 2 in the order of the refrigerating chamber 3, the vegetable compartment 4, and the vegetable compartment 4 in the left-right direction from the top. And, a large freezing room 7 arranged below them is provided.

The refrigerating room 3 and the vegetable room 4 are both storage rooms in the refrigerating temperature zone, and the opening on the front surface of the refrigerating room 3 is opened and closed by the left and right hinge opening / closing type left doors 3a and right doors 3b arranged side by side. Further, the opening on the front surface of the vegetable compartment 4 is opened and closed by the drawer type door 4a. The ice making chamber 5, the small freezing chamber 6, and the large freezing chamber 7 are all storage chambers in the freezing temperature zone, and the opening on the front surface of the ice making chamber 5 is opened and closed by the drawer-type door 5a, and the front opening of the ice making chamber 6 is on the front surface of the small freezing chamber 6. The opening is opened and closed by the drawer type door 6a, and the opening on the front surface of the large freezing chamber 7 is opened and closed by the drawer type door 7a. Hereinafter, the left door 3a and the right door 3b will be referred to as a refrigerating room door, the door 4a will be referred to as a vegetable room door, the door 5a will be referred to as an ice making room door, the door 6a will be referred to as a small freezing room door, and the door 7a will be referred to as a large freezing room door.

The left door 3a is provided with an operation panel 8 capable of inputting an operation mode setting of the refrigerator 1 and confirming an operating state of the refrigerator 1. As shown in FIG. 2, the operation panel 8 is provided with an adjusting unit 8a for adjusting the volume of music output from the speaker, an LED 8B for visually presenting the state of the refrigerator 1 by turning it on or off, and the like. ing. The operation panel 8 corresponds to an operation input unit.

Further, a water supply tank 9 is provided inside the refrigerating chamber 3. The water supply tank 9 stores water and supplies water to the ice making device 10 provided in the ice making chamber 5. The ice making device 10 automatically or when instructed by the user to make ice, as will be described later, produces ice using the water supplied from the water supply tank 9. Further, in the refrigerating chamber 3, a chilled chamber 30, which is a storage chamber in a so-called chilled temperature zone, is provided.

In the refrigerator compartment 3, a control unit 11 that controls the entire refrigerator 1 is arranged above the back surface thereof. Further, an upper speaker 12 is provided on the upper front side of the refrigerating chamber 3, and side speakers 13a and side speakers 13b are provided on the left and right sides on the front side side, respectively. However, the position of the control unit 11, the position and the number of each speaker, and the like are not limited to those shown in FIG.

The control unit 11 is composed of a microcomputer or the like (not shown), and as shown in FIG. 2, by executing a computer program stored in the storage unit 14, a functional unit provided in the refrigerator 1 can be used. Control. The storage unit 14 also stores sound effects and music data output from the speaker.

The control unit 11 controls each storage cycle 15 composed of a compressor, an evaporator, a condenser, etc., based on, for example, a storage chamber acquired by a sensor (not shown), an external temperature, humidity, and the like. Cool the room. That is, the control unit 11 also controls changes in the operating state of the refrigerator 1, such as a transition from a normal operating state to a low power consumption state, which will be described later.

Specifically, the control unit 11 controls the refrigerator 1 to operate in a low power consumption state, which consumes less power than in a normal operating state. This low power consumption state corresponds to, for example, a state in which the defrosting operation is not performed, a state in which the ice making operation is not performed, and the like. Alternatively, the control unit 11 rapidly creates an ice-making state in which ice is continuously generated until the ice-making chamber 5 is full, for example, in the small freezer chamber 6, based on a user's instruction from the operation panel 8 of the refrigerator 1. It is controlled to a one-at-one freezing state in which the food is frozen at once, a cooling state in which the food stored in the chilled chamber 30 is cooled to the chilled temperature zone, a thawed state in which the food is thawed, and the like.

The control unit 11 has a left door switch 16 that detects the opening / closing of the left door 3a, a right door switch 17 that detects the opening / closing of the right door 3b, a vegetable room door switch 18 that detects the opening / closing of the vegetable room door, and an opening / closing of the ice making room door. It is connected to the ice making room door switch 19, the small freezing room door switch 20 that detects the opening and closing of the small freezing room door, and the large freezing room door switch 21 that detects the opening and closing of the large freezing room door. It is possible to acquire the open / closed state of the door and the time elapsed since the door was opened by the timer 11a. Each door switch corresponds to a detection unit that detects the open / closed state of the door.

Further, the control unit 11 is connected to a sound control unit 22 that controls the output of music from each speaker. The sound control unit 22 is connected to the upper speaker 12, the side speaker 13a, the side speaker 13b, the storage unit 14, and the external input / output unit 23, and reads and reproduces the data stored in the storage unit 14 to play the speaker. Output music from. The sound control unit 22 functions as a sound effect / music output unit together with the control unit 11, the storage unit 14, and the speaker. Although the configuration in which the storage unit 14 is shared with the control unit 11 is illustrated in the present embodiment, a configuration in which a dedicated storage unit is connected to the sound control unit 22 may also be used.

The external input / output unit 23 is an interface for connecting an external storage medium such as a memory card 24 that stores music data output from the speaker. The sound control unit 22 reads out the data stored in the storage unit 14, the data stored in the memory card 24, or the data transferred from the memory card 24 to the storage unit 14, and outputs music from the speaker. The external input / output unit 23 can also be configured with an interface for wired communication or wireless communication.

Next, the operation of the above configuration will be described.
As described above, conventionally, buzzers and voice notifications have been performed. However, in the notification by the buzzer, considering that the refrigerator 1 can take a plurality of operating states as described above, even if it is possible to output a plurality of types of sounds by different scales and pitches, it is given to the user. The information that can be produced was limited.

In this case, it is considered that detailed information can be notified by performing the notification by voice. However, for example, in the case of warning that the door is in a half-door state, the user knows that the door is open even though the door is opened to clean the inside of the refrigerator. Nevertheless, repeated warnings by buzzer or voice may be annoying to the user and may reduce usability and maintainability, such as the need to open and close the door many times to stop the warning.

On the other hand, it is difficult for the refrigerator 1 to know whether the door is open or simply forgotten to close for cleaning, so it may be necessary to warn that the door is in a half-door state. It is a fact.

Therefore, in the present embodiment, a speaker is provided in the refrigerator 1 to notify the user by outputting music, thereby increasing the amount of information given to the user and suppressing deterioration of usability and maintainability. There is.

The refrigerator 1 of the present embodiment notifies the user by outputting sound effects and music from the speaker. The refrigerator 1 notifies the user of a warning, for example, by outputting music from a speaker. Specifically, the control unit 11 has closed the door if the closing of the door is not detected even after the preset waiting time has elapsed after the detection that the door has been opened has elapsed. Outputs music until is detected.

That is, the refrigerator 1 notifies, that is, warns that the opened door is in a half-door state in which the opened door has not been closed for a certain period of time or more by outputting music. In this case, it is preferable to use music to be output, such as Ravel's bolero, which is not so noisy and whose tune does not change so much.

As a result, for example, when the door is opened for a certain long time to clean the inside of the refrigerator, that is, when the user knows that the door is in the half-door state, the music is output comfortably. Can be cleaned. In addition, since the warning is indirectly given by outputting music, the discomfort given to the user can be reduced and the usability is reduced compared to the case where the warning is made directly by a buzzer sound or a voice message such as "Please close the door". And it is possible to suppress the deterioration of maintainability.

Further, the refrigerator 1 can notify the state of the refrigerator 1 by outputting music from the speaker. For example, when the refrigerator 1 is operating in a low power consumption state in which the power consumption is lower than that in the normal operating state, the refrigerator 1 outputs music at the timing when it is detected that the door is opened, thereby reducing the power consumption. Notify that it is in a state. In this case, it is preferable to output music different from the above-mentioned half-door warning, more preferably music that makes the person feel quiet.

As a result, it is possible to notify the user that the power consumption is low when the door is opened, so that the user who knows that the power consumption is low can quickly put in and take out food and close the door early. It will be possible to contribute to power saving.

Further, the refrigerator 1 can notify the state of the refrigerator 1 and warn the user by outputting music from the speaker. For example, if the door is not closed for a waiting time or longer when the refrigerator 1 is in a low power consumption state, it can warn that the refrigerator 1 is in a half-door state by outputting music. In this case, the refrigerator 1 can output music indicating that it is in the half-door state, or warns that it is in the half-door state by raising the pitch of the music indicating that it is in the low power consumption state. You can also do it.

At this time, when the refrigerator 1 is operating in a low power consumption state, the standby time until notifying that it is in the half-door state can be made shorter than in the normal operating state. In this case, relatively quiet music first informs you that the power consumption is low, and then when the standby period elapses, different music is output, which can prompt the door to close and consume. It is possible to reduce the possibility that the power consumption will increase.

Further, the refrigerator 1 can notify the refrigerator 1 of the response to the user's operation by outputting music from the speaker. For example, when the operation panel 8 instructs the refrigerator 1 to make ice at once, the refrigerator 1 outputs a sound effect such as "Dremi Fasolaside" in which the pitch is gradually increased, so that the refrigerator 1 is compared with a buzzer sound such as a simple "beep". Then, it is possible to clearly notify the user that the ice making state has started. That is, the refrigerator 1 can output a sound effect reminiscent of the content to be notified and a sound effect according to the notification situation, particularly a sound effect unique to the refrigerator 1, such as a situation assumed when the refrigerator 1 is used. ..

In this case, the refrigerator 1 outputs music or sound effect at the timing when it is detected that one of the doors has been opened, if the ice making is completed even once in the case of the ice making state at once. By doing so, it is possible to notify that the ice is being made at once and that ice has been generated. At this time, as the sound effect, for example, a sound effect such as "Karan, Karan" reminiscent of putting ice in a cup can be adopted. That is, the refrigerator 1 can be configured to select whether to output a sound effect or music according to the content to be notified. Thereby, the notification can be performed in a mode that is easier to understand.

Further, the refrigerator 1 outputs, for example, a sound effect in which the pitch is gradually lowered like "Doshira sofa milled" at the timing when the left door 3a is opened, for example, when the ice making state is completed at once. It is possible to clearly notify the user that the ice making state has ended at once. As a result, it is possible to notify the user who wants to use the ice quickly or to make a lot of ice at an appropriate timing that the ice has been generated, and the usability can be improved.

By the way, when ice is generated by the ice making device 10, it is necessary that water is stored in the water supply tank 9. Therefore, the refrigerator 1 needs to notify the user that the water supply tank 9 is empty when water is not stored in the water supply tank 9. However, if the notification is made even though the ice formation is not required, the notification may be excessive and the user may feel annoyed.

Although it is possible to detect that the water supply tank 9 is empty by the fact that the temperature of the ice tray does not reach around 0 ° C. after the water supply operation, a water level sensor may be provided. When the water level sensor is provided, it becomes possible to detect not only that the water has run out but also that the water is about to run out.

Therefore, the refrigerator 1 can change the timing and the number of notifications according to the content to be notified. Further, the refrigerator 1 can change the mode of notification, that is, the presence / absence of output of music and the number of times of output, depending on which storage room the door for which the opening is detected corresponds to.

For example, when notifying that the water supply tank 9 is empty, the refrigerator 1 is in the one-shot ice making state shown as "in one-shot ice making" in FIG. 3, or in the one-shot ice making state shown as "other than in one-shot ice making". The timing and number of times the music is output can be changed depending on whether or not the door is open and which door opening is detected as "operation" in FIG. In FIG. 3, outputting music is indicated as "music reproduction", and not outputting music is indicated as "no reproduction".

Specifically, since water is required in the water supply tank 9 when the ice is being made all at once, the water supply tank 9 of the refrigerator 1 is empty regardless of which door is opened. Outputs music to notify that it is in a state. This makes it possible to prevent ice from being generated because the water supply tank 9 is empty.

On the other hand, when the refrigerator 1 is not in the ice making state at once, the refrigerator 1 outputs music only once at the timing when the opening of the left door 3a or the right door 3b of the refrigerating chamber 3 is detected. As a result, it is possible to notify the user that there is no or little water, and it is possible to prevent excessive notification from being performed to the user who does not store water in the water supply tank 9 because the ice making device 10 is not used. be able to.

Further, the refrigerator 1 does not output music when it is detected that the vegetable compartment 4 doors or the freezing compartment doors (doors 6a, 7a) are opened when the ice is not made at once. This makes it possible to prevent excessive notification from being performed. Also, even if an instruction to release ice making at once is input, water is not required, so no music is output.

On the other hand, even if the refrigerator 1 is not in the ice making state at once, the water supply tank 9 is at the timing when the opening of the ice making chamber door is detected and at the timing when the instruction for making ice at once is input from the operation panel 8. Outputs music to notify that is empty. In this case, instead of outputting music, it is possible to notify that there is no or little water by outputting a sound effect such as "pop, pop" reminiscent of falling water droplets.

As a result, it is possible to notify the user who has opened the ice making chamber door or instructed to make ice at once, that is, the user who needs ice from now on, that there is no or little water in the water supply tank 9. Can be avoided in the situation where is not generated.

Similarly, in the case of a quick freezing state in which the inside of the small freezing chamber 6 is rapidly cooled, for example, the refrigerator 1 is in a quick freezing state by outputting music at the timing when the opening of any of the doors is detected. Can be notified. In this case, for example, it is possible to output a sound effect such as "Hugh, Hugh" reminiscent of a snowstorm or the like. As a result, it is possible to notify that the quick freezing state is in effect, and it is possible to prevent the small freezing chamber door from being inadvertently opened and the efficiency of the quick freezing from being lowered.

In this case, when the freezing state is completed, the refrigerator 1 is in the freezing state at once when the doors other than the small freezing room 6 are opened or when the doors other than the small freezing room 6 are closed. It can also be configured to notify that it has been completed. This makes it possible to notify a user who wants to freeze the next food at once, or who wants to freeze the next food at once and then store it in the large freezing chamber 7. The reason for excluding the small freezing room door is that if the small freezing room door is opened after the quick freezing state is completed, it can be presumed that the small freezing room door was opened to take out the food.

Further, when the cooling or thawing is completed in the chilled chamber 30, the refrigerator 1 can notify that the cooling or thawing is completed by outputting music at the timing when the opening of the door is detected. As a result, it is possible to immediately notify when the thawing is completed, and it is possible to prevent the quality of the thawed food material from deteriorating.

In this case, the refrigerator 1 can change whether to notify at the timing of opening or at the timing of closing, depending on the door in which the opening is detected. Specifically, the refrigerator 1 is notified based on whether or not the door detected to be opened is the door of the storage room provided with the functional unit, here the chilled room 30, to be notified. You can change the timing to do.

In the case of the present embodiment, the chilled chamber 30 is provided in the refrigerating chamber 3. Therefore, when the opening of the left door 3a or the right door 3b of the refrigerating room 3 is detected, the user will not forget to take it if the defrosting is completed by notifying at the timing of opening. it is conceivable that.

On the other hand, when the opening of the doors other than the refrigerating chamber 3 is detected after the thawing is completed, if the notification is given at the timing of opening, there is a possibility that the notification is related to the storage room in which the door is opened. Therefore, when the opening of the doors other than the refrigerating room 3 is detected, the completion of thawing is notified at the timing when the closing of the door is detected, so that the thawing is completed while reducing the risk of erroneous recognition. Can be notified.

Further, when the refrigerator 1 outputs a plurality of music at the same time, that is, when the timings of notification overlap, the refrigerator 1 determines the order of outputting sound effects or music based on a predetermined priority. Can be done. In the refrigerator 1 of the present embodiment, for example, in the case of notifying that thawing is completed in the chilled chamber 30 and notifying that the water supply tank 9 is empty, the notification that thawing is completed in the chilled chamber 30 has priority. The ranking is set high.

Although it is difficult to exemplify all combinations of priorities, for example, it is conceivable to raise the priority of notification regarding the freshness and storage stability of food to be higher than the priority of notification regarding power saving. In addition, although the notification of the half-door state is close to the highest priority because it is related to both storage stability and power saving, the notification timing is after the lapse of the standby time, so it overlaps with other notification timings. It is considered small.

According to the embodiment described above, the following effects can be obtained.
The refrigerator 1 is a user by outputting at least one of a speaker capable of outputting sound effects and music, a storage unit 14 storing sound effects and music data output from the speakers, and the speakers. A control unit 11 for notifying the user is provided.

As a result, instead of direct notification by buzzer sound or voice as in the past, indirect notification by sound effect or music can be performed, and the user feels annoyed or opens and closes the door to stop the warning. In addition to being able to suppress such problems, it is also possible to notify the user of an event that should be warned, such as a half-door state, and it is possible to reduce the possibility that the usability and maintainability of the refrigerator 1 will deteriorate. In addition, various sound effects and music can be used, and the amount of information given to the user can be increased.

More specifically, the refrigerator 1 notifies the user of a warning, the state of the refrigerator 1, and the response to the user's operation performed on the refrigerator 1, at least one of sound effects and music. By performing the output, the amount of information given to the user can be increased, and the deterioration of usability and maintainability can be suppressed.

In the refrigerator 1, the timing when the door is detected to be opened, the timing when the door is detected to be closed, and the predetermined waiting time have elapsed since the door was detected to be opened. Notification is performed at any of the timings that have been set. As a result, the notification can be performed at an appropriate timing, and the possibility of erroneous recognition by the user can be reduced. Further, at these timings, it can be determined that the user is in front of the refrigerator 1 with a high probability, so that reliable notification can be performed.

The refrigerator 1 has a timing of performing notification based on whether or not the door detected to be opened is the door of the storage room provided with the functional unit to be notified according to the content to be notified. , Change the number of notifications. As a result, it is possible to perform notification while reducing the possibility of excessive notification.

The refrigerator 1 determines whether to output a sound effect or music according to the content to be notified. As a result, the notification can be performed in a manner that is easy for the user to understand or intuitively understandable, and the possibility of erroneous recognition can be reduced.

Further, the refrigerator 1 may perform notification using data stored in an external storage medium or data stored in the storage unit 14 from the external storage medium in addition to the data stored in the storage unit 14. can. As a result, sound effects and music according to the user's preference can be output, and even a warning or the like can be notified without causing excessive noise or discomfort.

The operation panel 8 includes an adjusting unit 8a for adjusting the volume of the speaker. As a result, if the user feels that the volume is too loud during cleaning, the volume can be adjusted immediately, and maintainability can be improved. In this case, the volume is defaulted when it is detected that the door is closed after the volume is adjusted, or when a predetermined time has elapsed after it is detected that the door is closed after the volume is adjusted. It can be configured to return to the state of. As a result, it is possible to avoid a situation in which the warning of the half-door state is reduced during cleaning but the volume is forgotten to be returned to the original volume and the warning of the half-door state is not notified to the user.

In the embodiment, a configuration in which speakers are provided on the upper portion and the side portion of the refrigerating chamber 3 is exemplified, but the speakers can be provided at positions corresponding to the storage chamber. For example, when the quick freezing is completed in the small freezing room 6, if the music is output from the upper speaker 12 at the timing when the door of the refrigerating room 3 is opened, the music is generally played on the upper side of the head. There is a risk of misunderstanding that there is a notification target on the upper side of the room 3. Therefore, the functional unit to be notified Here, for example, by providing a speaker at a position corresponding to the small freezing chamber 6 and outputting voice from the speaker at the position corresponding to the notification target, the notification content can be grasped sensuously. It can be done and usability can be improved.

In the embodiment, the configuration in which the chilled chamber 30 is provided is exemplified, but for example, the small freezing chamber 6 can be configured such that the temperature zone can be switched and can be frozen and thawed.
In the embodiment, only the speaker is provided, but the installation of the buzzer is not excluded. For example, if it is a simple operation sound or the like, it can be notified by a buzzer sound. Further, for example, a relatively sharp buzzer sound such as "pee, beep" can be expected to be generally recognized by the user as a warning sound, so that a buzzer occurs when a failure related to the operation of the refrigerator 1 occurs. It is also possible to notify by sound. In addition to the situations shown in the examples, it is possible to perform notifications and warnings by sound effects and music. In addition, the content to be notified can be inferred by changing the volume and pitch of the sound effect and music.
