Description

  The present invention relates to an air blower such as a fan that is installed in a living room and is used for reducing the temperature of sensation due to direct airflow and circulating the air in the room.

  Conventionally, this type of air blower has an impeller and a motor enclosed in a base that serves as a base, and air is circulated from the annular air blower provided in the upper part of the base so that the air is blown horizontally to the floor surface. In addition, a home blower that generates a flow of air is known (for example, see Patent Document 1).

  Hereinafter, the blower will be described with reference to FIGS. 11 and 12.

  FIG. 11 shows a front view of the blower assembly 100, and FIG. 12 shows a cross-sectional view of the blower assembly 100. The blower assembly 100 has an annular nozzle 101 that defines a central opening 102. A motor 122 that creates an air flow through the annular nozzle 101 is disposed within the base 116 along with the motor housing 126. Further, the impeller (impeller) 130 is connected to a rotating shaft extending outward from the motor 122, and the motor 122 in which the diffuser 132 is positioned downstream of the impeller 130 is connected to an electrical connection unit and a power source. A plurality of selection buttons 120 allow the user to operate the blower assembly 100.

  With the above configuration, the blower assembly 100 operates as follows.

  When the user selects a predetermined button from the plurality of selection buttons 120 and the motor 122 is activated, air is sucked into the blower assembly 100 through the air inlet 124. Air flows through the outer casing 118 to the inlet 134 of the impeller 130. The air flow that exits the outlet 136 of the diffuser 132 and the exhaust portion of the impeller 130 is divided into two air flows that travel in opposite directions through the internal passage 110.

  The air flow is squeezed as it enters the mouth 112 and is further squeezed at the outlet 144 of the mouth 112. Due to this restriction, pressure is generated in the internal passage 110.

  The air flow thus created overcomes the pressure generated by the restriction and exits through the outlet 144 as a primary air flow. The primary air flow is directed or focused toward the user due to the arrangement of the guide portion 148. The secondary air flow is generated by the suction of air from the outside environment, particularly from the area around the outlet 144 and around the outer edge of the annular nozzle 101. This secondary air flow passes through the central opening 102 where there is a total air flow that mixes with the primary air flow and is discharged forward from the blower assembly 100.

JP 2010-077969 A

  In such a conventional blower, since the primary air flow exits from the outlet, the secondary air flow is generated by the suction of air from the outside environment, particularly the area around the outlet and the outer edge of the annular nozzle. The suction of air is large in the vicinity of the annular nozzle in the central opening, and the suction of air becomes smaller as the center of the central opening is approached. For this reason, there existed a subject that air could be blown out only in cyclic | annular form and the ventilation range could not be adjusted.

  Then, this invention solves the said conventional subject, and it aims at providing the air blower which can adjust the ventilation range of the air attracted by the blowing of the high pressure air from a blower outlet.

  In order to achieve the above-mentioned object, a blower according to the present invention includes a suction port for taking in air, an impeller for generating high-pressure air, and a motor for driving the impeller. And a plurality of nozzles erected from one surface of the housing, and the nozzles are generated on the side portions of the high-pressure air generator in a direction perpendicular to the direction in which the nozzles are erected. Provided with a blow-out port for blowing out the high-pressure air, and provided with a duct for guiding high-pressure air to the blow-out port. The nozzle has a vertically long section in the blow direction, and is provided in a plurality of nozzles. A blower device provided with a gap so that each of the blowout outlets that are provided is on the same plane, and an air induction air passage that is induced by the air blown out from the blowout opening is formed by the gap. Blow out high-pressure air Wherein are those the number and position of the air outlet with a changing means for selecting, thereby it is to achieve the intended purpose.

  According to the present invention, since the changing means for selecting the number and position of the outlets for blowing the high-pressure air is provided, the number and position of the outlets for blowing the high-pressure air can be selected. The air that is attracted by the high-pressure air that is blown out can also adjust the air blowing range according to the position and number of users, and has the effect of improving comfort.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Assumption example 1)
As shown in FIG. 1, the air blower 11 that is the premise of the present embodiment includes a plurality of nozzles 13 (six in the precondition example 1) that are erected from the upper surface of the housing 12. Yes. In the first prerequisite example, the housing 12 is erected from the upper surface.

  As shown in FIGS. 2 and 3, the housing 12 includes a suction port 14 for taking air into the housing 12, an impeller 15 for generating high-pressure air, and a motor 16 for driving the impeller 15. And a high-pressure air generator 17.

  As shown in FIG. 2, high pressure air is provided in one direction perpendicular to the direction in which the nozzle 13 is erected on one side of the nozzle 13 located on the front surface (left side in FIG. 2) of the blower 11. A blower outlet 18 for blowing out the high-pressure air generated in the generator 17 is provided.

  Inside the nozzle 13, a duct 19 is provided for guiding high-pressure air to the outlet 18. The number of ducts 19 is at least equal to the number of nozzles 13.

  As shown in FIG. 3, a chamber space 20 that divides high-pressure air into each nozzle is provided between the high-pressure air generator 17 and the plurality of ducts 19.

  As shown in FIG. 4 in plan view, the nozzle 13 has a vertically long cross section in the blowing direction with respect to the direction in which the nozzle 13 is erected. The plurality of nozzles 13 are provided with gaps so that the air outlets 18 are flush with each other, and the air attraction air passages 21 that are attracted by the airflow blown out from the air outlets 18 are formed by the gaps of the nozzles 13. It is formed on the outside. That is, in the example of the present embodiment, since six nozzles 13 are provided, five induction air passages 21 can be formed in the gaps sandwiched between the nozzles 13, each having fewer than the number of the nozzles 13. The length of the gap is equal to or longer than the length in the vertical direction (the width of the nozzle 13) with respect to the blowing direction in the vertical section of the nozzle 13, and the length of the nozzle 13 in the standing direction from the top surface of the casing 12. In this embodiment, for example, the width of the nozzle 13 is 30 mm, the length of the nozzle 13 in the standing direction is 600 mm, the length of the gap is 100 mm, and the nozzle 13 is blown out. The case where the direction length is 200 mm is shown. Further, in this example, the cross-sectional shape in the vertical direction of the nozzle 13 is a rectangular shape, but it may be vertically long in the blowing direction, and may be another shape such as an ellipse. Further, as shown in FIG. 4, the plurality of nozzles 13 have a wide angle so that the air blowing direction is away from the central nozzle 13 as it goes from the center of the housing 12 to the nozzle 13 provided outside. Is provided.

  As shown in FIG. 2, a wind direction adjusting rib 23 that adjusts the wind direction of the nozzle 13 in the standing direction is provided near the air outlet 18 in the nozzle 13. Here, the plurality of nozzles 13 indicate three or more. Further, the uniformity of the wind speed is focused on the distribution of the wind speed of the surface airflow where the blown air flow 24 and the induced air flow 25, which will be described later, join, and is observed on a plane viewed from the front at a predetermined distance from the air outlet 18. It is shown that the distribution of the wind speed is within a predetermined range. That is, the minimum wind speed on the plane is allowed to be at least half of the maximum wind speed. Moreover, high pressure air shall show the air above atmospheric pressure.

  According to the above configuration, when the blower 11 is operated, the motor 16 is driven and the impeller 15 rotates, so that the indoor air is taken into the blower 11 from the suction port 14 as shown in the internal flow 22. Then, it passes through the impeller 15 and reaches the chamber space 20. In the chamber space 20, the high-pressure air is divided into a plurality of ducts 19, passes through the respective ducts 19, the air direction in the nozzle 13 standing direction is adjusted by the air direction adjusting ribs 23 provided in the vicinity of the air outlet 18, and is blown out from the air outlet 18. , A blown air flow 24 is obtained.

  That is, as shown in FIG. 1, the air outside the induction air passage 21 and the outermost nozzle 13 is attracted by the blown air flow 24, resulting in an induced air flow 25. The blown air flow 24 and the induced air flow 25 merge in front of the blowing device 11 in the blowing direction, and can blow a surface air flow of purified air having a substantially uniform wind speed over a wide range. At this time, since the impeller 15 is included in the housing 12, the user cannot make contact with the outside, so that anxiety due to contact can be eliminated.

  In addition, the nozzle 13 is arranged with a gap so that the air outlet 18 is flush with the air outlet, so that the air flow to be blown becomes a surface air current.

Moreover, since the wind direction adjustment rib 23 can expand the wind direction in the standing direction of the nozzle 13 by adjusting the elevation angle, it can blow air over a wider range than the length in the standing direction of the nozzle 13. In other words, the air can be blown above the height of the blower 11.
(Embodiment 1)
Now, as shown in FIG. 5, the air blower 11 according to the first embodiment is different from the air blower 11 according to the first example in that the nozzle 13 is an opening / closing device as a changing unit that selects the number and position of the air outlets 18. 26. As shown in FIG. 5A, the opening / closing device 26 ejects an airflow, a substantially flat plate-like member 27 that can cover the air outlet 18, a stepping motor 28 that rotationally drives the plate-like member 27. An operation unit (not shown) for selecting the position of the nozzle 13 is provided. The stepping motor 28 is disposed above the nozzle 13. The plate-like member 27 is rotated by the rotation of the stepping motor 28, and the air outlet 18 can be opened and closed.

  FIGS. 5B and 5C show an open state in which the air outlet 18 is opened and a closed state in which the air outlet 18 is closed, respectively. The opening / closing device 26 is provided in each nozzle 13, and can open and close the air outlet 18 that blows out high-pressure air independently.

  According to the said structure, according to the number of users and a position, a ventilation range can be adjusted and comfort can be improved.

  For example, when two users (users A and B) are separated, even if all the nozzles 13 are opened and used as shown in FIG. 6A, the blown air flow 24 and the induced air flow from the middle two are used. 25 is wasted. By selecting the position of the nozzle 13 that ejects the airflow with an operation unit (not shown), the stepping motor 28 rotates the plate-like member 27 to open the selected nozzle 13 and eject the airflow. Therefore, it is possible to blow air according to the position of the user. That is, as shown in FIG. 6B, the two outlets 18 located in the middle of the six nozzles 13 that do not correspond to the user can be closed and used.

  In addition, the number of nozzles that eject the airflow is selected by the operation unit (not shown), and the airflow can be increased. That is, the stepping motor 28 rotates the plate-like member 27 and closes the middle two members, so that the supply of the blown air flow 24 is stopped in the portion not hit by the user, and the high-pressure air remains. Will be distributed to the four. As a result, the blown air flow 24 from the air outlet 18 in the open state increases in wind speed, the amount of the induced air flow 25 increases, and the comfort of two distant users improves.

  In addition, when all the six airflows are sufficient, the output of the motor 16 can be reduced and the power consumption can be reduced. In this case, the air volume can be easily adjusted by providing a device for controlling the rotational speed of the motor 16.

  In the present embodiment, the middle two are closed, but depending on the situation of the user, it is possible to close only the right half and close every other.

(Embodiment 2)
In the second embodiment, another embodiment will be described in place of the opening / closing device 26. Only differences from Premise Example 1 and Embodiment 1 will be described. The same constituent elements as those in Premise Example 1 and Embodiment 1 are denoted by the same reference numerals, and detailed description thereof is omitted to avoid duplication.

  FIG. 7 shows a configuration diagram of the blower 31. FIG. 7A is a cross-sectional view of the housing 12 of the blower 31 as viewed from the front.

  Between the high pressure air generation part 17 in the housing | casing 12 and the several duct 19, the chamber space 20 which diverts high pressure air to each nozzle 13 is provided. As shown in FIG. 7A, in the present embodiment, an airway opening / closing device 33 is provided at a branch portion 32 from the chamber space 20 to each duct 19.

  The opening / closing device 33 includes a sheet-shaped blocking member 34 that blocks the air path, and a stepping motor 35 for winding the blocking member 34.

  FIGS. 7B and 7C respectively show an open state in which the branch portion 32 is opened and a closed state in which the branch portion 32 is closed. As shown in FIG. 7C, the stepping motor 35 rotates and the sheet-shaped blocking member 34 is expanded so that the branch portion 32 is blocked, so that the air passage from the chamber space 20 to the duct 19 is formed in the branch portion 32. This shuts off and prevents high-pressure air from flowing into the duct 19. Further, the stepping motor 35 rotates and the sheet-like blocking member 34 is wound up so that the duct 19 and the chamber space 20 communicate with each other, and high-pressure air can flow into the duct 19.

  The opening / closing device 33 is provided in each branching portion 32 of each duct 19, and can individually open and close the branching portions 32 that flow high-pressure air.

  FIG. 7 (d) shows a cross-section of the state in which the two outlets 18 in the middle of the six are closed as viewed from the chamber space 20 side toward the duct 19. That is, in FIG. 7D, the states are “open”, “open”, “closed”, “closed”, “open”, and “open” sequentially from the left.

  According to the above configuration, the air blowing range can be adjusted in accordance with the number and positions of users as in the first embodiment, and comfort can be improved.

  Further, since the opening / closing device 33 is housed in the housing 12, the air blowing range can be changed without changing the external appearance, and the air blowing device excellent in design can be obtained.

  In addition, since the impeller 15 is included in the housing 12, the user cannot make contact with the outside, so that anxiety due to contact can be eliminated.

  Furthermore, since the user's hand does not come into contact with the switchgear 33, there is an effect that the risk of failure of the switchgear 33 can be reduced.

  The opening / closing device 33 is a sheet-like blocking member 34 and a winding stepping motor 35. However, the opening / closing device 33 may be a mechanism that opens and closes a flat plate, or a structure that can block an air path by sliding it. There is no difference in the effect.

(Embodiment 3)
In the third embodiment, another embodiment will be described in place of the switching device 26 or the switching device 33. Only differences from the first and second embodiments will be described. The same constituent elements as those in Premise Example 1 and Embodiments 1 and 2 are denoted by the same reference numerals, and detailed description thereof is omitted to avoid duplication.

  FIG. 8 shows a configuration diagram of the blower 41. The air blower 41 according to the present embodiment is configured such that after the nozzle 43 is removed from the housing 42 and the nozzle 43 is removed by the cover 44, the lid can be closed.

  FIG. 8A shows a state where one of the six nozzles 43 is removed and the cover 44 is attached. FIG. 8B is a perspective view of the removed nozzle, and FIG. 8C is a perspective view of the cover 44.

  According to the said structure, since the induction | guidance | derivation wind path 21 spreads by removing the nozzle 43, wind path resistance will reduce. Therefore, the attracted air is easy to flow, the wind speed attenuation of the airflow is reduced, and it is possible to reach far away.

  Moreover, FIG. 9 has shown an example which installed the air blower 41 in the form accommodated in the hollow of the ceiling 50 or the indoor wall 51. FIG. By attaching it to the ceiling as shown in FIG. 9A, it can be used like a ceiling fan or the like for circulating indoor air. Moreover, FIG.9 (b) can also be made not to interfere with a person's activity even if it installs by storing in the hollow of a wall.

  However, as shown in FIG. 9 (c), in the installation method of FIGS. 9 (a) and 9 (b), since the high pressure air is blown out from the entire front surface of the blower 41, the attracted air is It becomes impossible to go around to the back side of the nozzle 43, the amount of supplied air is reduced, and the air volume is reduced.

  Therefore, the configuration of this embodiment is provided, and as shown in FIG. 10, the nozzle 43 is removed in accordance with the surrounding environment, thereby securing a supply path for attracted air and being hardly affected by the blown air flow. A space can be created. That is, the air that is attracted through the space can go around to the back side of the nozzle 43. Thereby, the attracted air is sufficiently supplied, and it is possible to prevent a decrease in the attracted air. (In FIG. 10, the left and right outermost nozzles 43 are removed from the six nozzles).

  In the present embodiment, it is possible to supply air that is attracted by removing the nozzle 43. However, without removing the nozzle 43, high-pressure air is blown out from any one of the six outlets 18. It is possible to obtain the same effect by stopping the operation. In FIG. 10, the left and right outermost nozzles 43 are removed from the six nozzles, but the same effect can be obtained even when the nozzles 43 other than the outermost are removed.

  In this embodiment, the cover 44 is completely removed from the housing 42, but may be connected to the housing 42. For example, when the nozzle 43 is attached to the housing 42, the cover 44 is pushed into the housing 42, the chamber space 20 communicates with the duct 19, and when the nozzle 43 is removed, a repulsive force such as a spring is used to automatically It may be configured to be covered with.

    The air blower according to the present invention can be installed on the floor, ceiling, or wall of a living room because it can provide an air flow with a substantially uniform wind speed over a wide range while eliminating the anxiety caused by the user's contact by including the impeller. It is useful as a variety of blower devices used for reducing the temperature of sensation due to direct airflow and circulating indoor air.
