JP 2005-257172 A

The storage facility requires a cooler for each space and multiple doors, resulting in high manufacturing costs. Also, the storage facility requires a cooler for each of the multiple spaces in the storage room separated by partition members, reducing the volume of space in the storage room in which items can be stored.

The object of the present invention is to provide a storage facility that does not require multiple coolers and doors, even when storing items with multiple storage temperatures at the same time, and that can suppress a decrease in the volume of the space in the storage room where items can be stored.

To achieve the above-mentioned objective, the storage facility of the present invention is a storage facility that includes a box body in which a storage chamber for storing items is formed, and a door that opens and closes an opening provided on the front surface of the box body, a partition member that divides the storage chamber in the vertical or width direction, a cooler that is provided on the side of one of the multiple spaces formed by dividing the storage chamber with the partition member and that cools the air in the one space, and a door duct that is provided on the back surface of the door and that allows a portion of the air in the one space to flow into the other spaces.

According to the storage facility of the present invention, by cooling one space in a storage room in which a cooler is installed using a portion of the air in the other space, it is possible to cool the other space to a set temperature higher than the set temperature of the one space, making it possible to store items in multiple temperature ranges without requiring multiple coolers and doors.

Figures 1 to 7 show one embodiment of the present invention.

The storage facility 1 of the present invention is installed, for example, in a warehouse of a convenience store or outdoors within the premises of a convenience store, and is used to store items such as boxed lunches and fresh foods that require temperature control. The storage facility 1 stores synthetic resin cases that contain multiple items, so-called boxed lunches, stacked vertically inside.

As shown in Figures 1 and 2, this storage facility 1 includes a storage facility body 10 with an opening 10a on the front, a door 20 for opening and closing the opening 10a of the storage facility body 10, and a partition member 30 that is detachably attached to the storage facility body 10.

The storage body 10 is made of a thermally insulating material and is a box having a bottom surface 10b, a back surface 10c, a top surface 10d, and a pair of side surfaces 10e, as shown in Figures 2 to 4.

A bottom panel 11, a back panel 12, and a top panel 13 are provided on the inside of the storage body 10 at intervals from the inner surfaces of the bottom portion 10b, the back portion 10c, and the top portion 10d. As a result, inside the storage body 10, a storage chamber 14 is formed, which is a space surrounded by the pair of side portions 10e, the bottom panel 11, the back panel 12, and the top panel 13, and a ventilation passage 15 is formed that extends continuously between the bottom portion 10b and the bottom panel 11, between the back portion 10c and the back panel 12, and between the top portion 10d and the top panel 13.

The storage chamber 14 has a plurality of protruding portions 14a that protrude from the inner surfaces of the pair of side portions 10e and the front surface of the back panel 12 and extend in the vertical direction. When a food container is stored in the storage chamber 14, the protruding portions 14a form gaps between the inner surfaces of the pair of side portions 10e and the front surface of the back panel 12 of the storage chamber 14 and the side surfaces of the food container, thereby positioning the food container relative to the storage chamber 14. The storage chamber 14 has an attachment portion 14b for attaching the partition member 30, slightly below the center in the vertical direction. The attachment portion 14b does not have a protruding portion 14a, and is a gap between the protruding portions 14a and the protruding portions 14a that are spaced apart in the vertical direction. In addition, the storage chamber 14 has a storage portion 14c at its lower end for storing the partition member 30. The storage portion 14c does not have a protruding portion 14a, and is a gap between the lower end of the protruding portion 14a and the bottom panel 11. Furthermore, as shown in Figures 3 and 4, the storage chamber 14 is provided with an upper temperature sensor 14d for detecting the temperature inside the storage chamber 14 above the mounting portion 14b, and a lower temperature sensor 14e for detecting the temperature inside the storage chamber 14 below the mounting portion 14b.

As shown in Figures 3 and 4, the ventilation passage 15 has a bottom side ventilation passage 15a extending in the front-rear direction along the bottom surface portion 10b, a rear side ventilation passage 15b extending in the up-down direction along the rear surface portion 10c, and an upper side ventilation passage 15c extending in the front-rear direction along the upper surface portion 10d.

The front end of the bottom side ventilation passage 15a is connected to the underside of the storage chamber 14 via an intake port 15a1 provided across the width at the lower end side of the opening 10a of the storage body 10. The rear end of the bottom side ventilation passage 15a is connected to the lower end of the rear side ventilation passage 15b. A lower circulation fan 15a2 is provided in the bottom side ventilation passage 15a as a second fan for sucking air from the storage chamber 14 through the intake port 15a1 and circulating it toward the rear side ventilation passage 15b.

The lower end of the rear ventilation passage 15b is connected to the rear end of the bottom ventilation passage 15a. The upper end of the rear ventilation passage 15b is connected to the rear end of the top ventilation passage 15c. The rear ends of the top ventilation passage and the bottom ventilation passage of the partition member 30, which will be described later, are connected to the rear ventilation passage 15b via the duct connection hole 12a that extends in the width direction, slightly below the vertical center of the back panel 12.

As shown in Figs. 5 and 6, the duct connection hole 12a is opened and closed by a blocking member 12a1 that is provided so as to be movable in the vertical direction. The blocking member 12a1 is fixed to the rear panel 12 by a thumb screw with the duct connection hole 12a open or closed. The rear ventilation passage 15b located behind the duct connection hole 12a is provided with a guide member 15b1 for guiding a part of the air flowing through the rear ventilation passage 15b to the front of the duct connection hole 12a. As shown in Fig. 2, the guide member 15b1 has a width size that is approximately the same as that of the duct connection hole 12a, and is disposed in the center of the width of the rear ventilation passage 15b. Therefore, the rear ventilation passage 15b communicates with the space below and above the guide member 15b1 through the gaps on both sides of the width of the guide member 15b1.

Furthermore, as shown in Figures 3 and 4, the rear ventilation passage 15b is provided with a lower heating section 15b2 as a second heating section for heating the air flowing through the rear ventilation passage 15b below the duct connection hole 12a, and an upper heating section 15b3 as a first heating section for heating the air flowing through the rear ventilation passage 15b above the duct connection hole 12a. The lower heating section 15b2 and the upper heating section 15b3 are each a sheet-shaped electric heater.

The rear end of the upper ventilation passage 15c is connected to the upper end of the rear ventilation passage 15b. The upper ventilation passage 15c has a circulation upper ventilation passage 15c2 whose front end is connected to the upper part of the storage chamber 14 through an outlet 15c1 provided in the width direction at the upper end of the opening 10a of the storage body 10 as shown in FIG. 3, and an air supply upper ventilation passage 15c3 whose front end is connected to the upper end of a door duct of the door 20 described later as shown in FIG. 4. In the circulation upper ventilation passage 15c2, an upper circulation fan 15c4 as a first fan for circulating the air that has circulated through the rear ventilation passage 15b toward the outlet 15c1, and a cooler 15c5 for cooling the air circulating through the circulation upper ventilation passage 15c2 are provided. In addition, the upper air supply passage 15c3 is equipped with an air supply fan 15c6 as a third fan for circulating the air that has flowed through the rear air passage 15b toward the door duct.

A machine room 16 is formed on the top surface of the top surface portion 10d of the storage body 10 to house components that make up the refrigeration cycle, such as a compressor, a condenser, and an expansion valve (not shown). The cooler 15c5 arranged in the upper ventilation passage 15c2 for circulation is connected to the compressor, condenser, and expansion valve in the machine room 16, and functions as an evaporator for the refrigeration cycle.

As shown in Figs. 1 and 2, the door 20 is a rectangular member having thermal insulation properties, and one end in the width direction is supported rotatably at one end in the width direction of the front end of the storage body 10. A handle 21 is provided at the other end in the width direction of the door 20, which the user grasps with his/her hand when opening and closing the door 20. As shown in Figs. 2 to 4, a door duct 22 is provided on the back surface of the door 20, extending vertically across the width direction. In addition, a plurality of protrusions 23 are formed on the back surface of the door 20, which extend vertically and protrude into the inside of the storage chamber 14.

When the opening 10a of the storage body 10 is closed by the door 20, the upper end of the door duct 22 communicates with the upper ventilation passage 15c3 for air supply of the upper ventilation passage 15c, and the lower end of the door duct 22 communicates with the lower side of the storage room 14.

When the partition member 30 is attached to the mounting portion 14b of the storage chamber 14 as shown in Figs. 3 and 4, the front end of the partition member 30 abuts against the rear surface of the door duct 22 across the width. As a result, the lower end of the door duct 22 communicates only with the space on the lower side of the storage chamber 14. As shown in Fig. 5, the partition member 30 has a heat insulating portion 31 that divides the storage chamber 14 in the vertical direction, an upper surface side duct 32 that is provided on the upper surface side of the heat insulating portion 31 and serves as a first duct through which air circulating in the upper space of the storage chamber 14 flows, and a lower surface side duct 33 that is provided on the lower surface side of the heat insulating portion 31 and serves as a second duct through which air circulating in the lower space of the storage chamber 14 flows. When the partition member 30 is attached to the mounting portion 14b, it is in a state of dividing the storage chamber 14 into an upper space and a lower space. When the partition member 30 is attached to the storage portion 14c in the storage chamber 14, it is in a stored state.

When the partition member 30 is attached to the mounting portion 14b, the upper surface duct 32 extends in the front-rear direction along the upper surface of the heat insulating portion 31, and has an inlet 32a at its front end for allowing air to flow in from the space above the storage chamber 14. When the partition member 30 is attached to the mounting portion 14b, the rear end of the upper surface duct 32 communicates with the rear surface ventilation passage 15b, and allows the air flowing in from the inlet 32a to flow into the rear surface ventilation passage 15b.

When the partition member 30 is attached to the mounting portion 14b, the lower duct 33 extends in the front-rear direction along the lower surface of the heat insulating portion 31, and has an outlet 33a at its front end for discharging air into the space below the storage chamber 14. When the partition member 30 is attached to the mounting portion 14b, the rear end of the lower duct 33 communicates with the rear ventilation passage 15b, and a portion of the air flowing below the rear ventilation passage 15b flows in and flows out from the outlet 33a.

As shown in FIG. 7, the storage facility 1 configured as above can maintain the inside of the storage chamber 14 at a single temperature of 4°C or 20°C by storing the partition member 30 in the storage section 14c in the storage chamber 14. At this time, the lower circulation fan 15a2 and the upper circulation fan 15c4 are constantly driven with the supply air fan 15c6 stopped.

As a result, the air flowing through the circulation upper ventilation passage 15c2 of the upper ventilation passage 15c is cooled by the cooler 15c5 and discharged from the discharge port 15c1 into the storage chamber 14. The air discharged from the discharge port 15c1 flows downward along the front side of the storage chamber 14 and is sucked into the bottom ventilation passage 15a via the intake port 15a1. The air sucked into the bottom ventilation passage 15a is sent to the rear ventilation passage 15b by the lower circulation blower 15a2, flows upward within the rear ventilation passage 15b, and flows into the circulation upper ventilation passage 15c2.

Here, if the temperature inside the storage chamber 14 is higher than the set temperature inside the storage chamber 14, which is 4°C or 20°C, the air cooling capacity of the cooler 15c5 is controlled to adjust the temperature inside the storage chamber 14 to the set temperature.

In addition, when the temperature inside the storage chamber 14 is lower than the set temperature inside the storage chamber 14, which is 4°C or 20°C, the cooling of the air by the cooler 15c5 is stopped or the cooling capacity is reduced, and the air circulating through the rear ventilation passage 15b is heated by one or both of the lower heating section 15b2 and the upper heating section 15b3, thereby adjusting the temperature inside the storage chamber 14 to the set temperature.

As shown in Figs. 3 and 4, the storage facility 1 can maintain the upper side of the storage room 14 at 4°C and the lower side at 20°C, a different temperature from the upper side, by attaching the partition member 30 to the mounting portion 14b in the storage room 14. At this time, in the rear ventilation passage 15b, as shown in Fig. 5, the blocking member 12a1 is moved upward to open the duct connection hole 12a, and the rear end side of the upper duct 32 and the lower duct 33 of the partition member 30 are connected to the rear ventilation passage 15b. The lower circulation fan 15a2 and the upper circulation fan 15c4 are driven at all times. Furthermore, the supply air fan 15c6 is controlled to switch between driving and stopping based on the temperatures detected by the upper temperature sensor 14d and the lower temperature sensor 14e.

As a result, in the space above the storage chamber 14, with the supply air blower 15c6 stopped, the air flowing through the circulating upper ventilation passage 15c2 of the upper ventilation passage 15c is cooled by the cooler 15c5 and discharged from the discharge port 15c1 to the upper side of the storage chamber 14. The air discharged from the discharge port 15c1 flows downward along the front side of the storage chamber 14 and flows into the upper duct 32 of the partition member 30 through the inlet 32a. The air that flows into the upper duct 32 of the partition member 30 flows to the rear end of the upper duct 32 and flows into the middle part of the rear ventilation passage 15b. The air that flows into the middle part of the rear ventilation passage 15b flows into the circulating upper ventilation passage 15c2 of the upper ventilation passage 15c.

In the space below the storage chamber 14, with the air supply blower 15c6 stopped, the air flowing out of the outlet 33a of the lower duct 33 of the partition member 30 flows downward along the front side of the storage chamber 14 and flows into the bottom ventilation passage 15a via the intake port 15a1. The air that flows into the bottom ventilation passage 15a is sent by the lower circulation blower 15a2 and flows into the rear ventilation passage 15b from the lower end, and flows upward through the rear ventilation passage 15b. The air that flows below the rear ventilation passage 15b is guided by the guide member 15b1 and flows into the lower duct 33 of the partition member 30.

When the supply air blower 15c6 is driven, part of the air flowing above the rear ventilation passage 15b flows into the circulation upper ventilation passage 15c2 of the upper ventilation passage 15c. The other air flowing above the rear ventilation passage 15b flows into the supply upper ventilation passage 15c3. The air that has passed through the supply upper ventilation passage 15c3 flows into the door duct 22, passes through the door duct 22, and flows into the space below the storage chamber 14.

In addition, when the air supply fan 15c6 is driven, the air flowing from the door duct 22 into the space below the storage chamber 14 flows downward along the front side of the storage chamber 14 together with the air flowing out from the outlet 33a of the lower duct 33 of the partition member 30, and flows into the bottom side ventilation passage 15a through the intake port 15a1. The air flowing into the bottom side ventilation passage 15a flows into the rear side ventilation passage 15b from the lower end by the lower circulation fan 15a2, and flows upward through the rear side ventilation passage 15b. A part of the air flowing below the rear side ventilation passage 15b is guided by the guide member 15b1 and flows into the lower side duct 33 of the partition member 30. In addition, the other air flowing below the rear side ventilation passage 15b flows into the upper side of the rear side ventilation passage 15b through the gaps on both sides of the width direction of the guide member 15b1. Here, the same amount of air flows into the upper side of the rear ventilation passage 15b as the air that flows into the space below the storage chamber 14 from the door duct 22.

Here, if the temperature of the upper space in the storage chamber 14 is higher than the set temperature of 4°C in the storage chamber 14 and the temperature of the lower space in the storage chamber 14 is higher than the set temperature of 20°C in the storage chamber 14, the air cooling capacity of the cooler 15c5 is controlled to adjust the temperature of the upper space in the storage chamber 14 to the set temperature. In the lower space in the storage chamber 14, the air temperature is cooled to the set temperature by introducing air from the upper space in the storage chamber 14 using the air supply blower 15c6. In the lower space in the storage chamber 14, the air supply blower 15c6 is controlled to switch between driving and stopping based on the temperature detected by the lower temperature sensor 14e, and the temperature is adjusted to the set temperature.

When the temperature of the upper space in the storage chamber 14 is higher than the set temperature of 4°C in the storage chamber 14 and the temperature of the lower space in the storage chamber 14 is lower than the set temperature of 20°C in the storage chamber 14, the air cooling capacity of the cooler 15c5 is controlled to adjust the temperature of the upper space in the storage chamber 14 to the set temperature. In the lower space in the storage chamber 14, with the air supply blower 15c6 stopped, the lower heating unit 15b2 heats the air flowing through the rear ventilation passage 15b until the temperature reaches the set temperature. In the lower space in the storage chamber 14, the lower heating unit 15b2 is controlled to switch between driving and stopping based on the temperature detected by the lower temperature sensor 14e, and the temperature is adjusted to the set temperature.

In addition, when the temperature of the upper space in the storage chamber 14 is lower than the set temperature of 4°C in the storage chamber 14 and the temperature of the lower space in the storage chamber 14 is lower than the set temperature of 20°C in the storage chamber 14, the cooling of the air by the cooler 15c5 is stopped or the cooling capacity is reduced, and the air supply fan 15c6 is driven to heat the air flowing through the rear ventilation passage 15b by the lower heating section 15b2 and the upper heating section 15b3, respectively. As a result, the upper space in the storage chamber 14 is heated by the upper heating section 15b3, and the air in the lower space heated by the lower heating section 15b2 is supplied by the air supply fan 15c6, so that the temperature is heated until it reaches the set temperature. The upper heating section 15b3 and the air supply fan 15c6 are stopped when the temperature of the upper space in the storage chamber 14 rises to the set temperature. The upper space in the storage chamber 14 is controlled to have the temperature adjusted to the set temperature by switching between on and off the upper heating unit 15b3 and the air supply fan 15c6 based on the temperature detected by the upper temperature sensor 14d. The lower space in the storage chamber 14 is heated by the lower heating unit 15b2 until the temperature reaches the set temperature. The lower space in the storage chamber 14 is controlled to have the temperature adjusted to the set temperature by switching between on and off the lower heating unit 15b2 based on the temperature detected by the lower temperature sensor 14e.

In this way, the storage facility 1 of this embodiment is provided with a door duct 22 that is provided on the back surface of the door 20 and allows some of the air in the upper space of the storage chamber 14 to flow into the lower space.

As a result, by supplying some of the air from the upper space in which the cooler 15c5 is installed to the lower space via the door duct 22, it is possible to cool the lower space to a set temperature different from the set temperature of the upper space, making it possible to simultaneously store items with multiple storage temperatures without the need for multiple coolers and doors.

In addition, the rear ventilation passage 15b allows the same amount of air to flow from the lower space to the upper space as the air that flows from the upper space to the lower space through the door duct 22.

This makes it possible to maintain the same pressure in the upper and lower spaces of the storage chamber 14, allowing air from the upper space to flow reliably into the lower space through the door duct 22.

It also includes an upper circulation fan 15c4 that circulates air in the upper space of the storage chamber 14, and a lower circulation fan 15a2 that circulates air in the lower space.

This allows the temperature in the entire upper and lower spaces of the storage chamber 14 to be uniform, making it possible to maintain all stored items at the desired temperature.

The system also includes an air supply fan 15c6 that circulates air through the door duct 22, an upper temperature sensor 14d, and a lower temperature sensor 14e, and the operation of the air supply fan 15c6 is controlled based on the temperatures detected by the upper temperature sensor 14d and the lower temperature sensor 14e.

As a result, by controlling the operation of the air supply blower 15c6, the air flow between the upper and lower spaces of the storage chamber 14 can be adjusted, making it possible to reliably maintain the set temperature in each of the upper and lower spaces of the storage chamber 14.

The upper surface of the partition member 30 is provided with an upper duct 32 through which air circulates in the upper space, and the lower surface of the partition member 30 is provided with a lower duct 33 through which air circulates in the lower space.

As a result, air flowing through the lower part of the upper space of the storage chamber 14 flows through the upper duct 32 and enters the rear ventilation passage 15b, and air flowing through the rear ventilation passage 15b and the upper part of the lower space of the storage chamber 14 flows through the lower duct 33, so that the air flow is not impeded by the items stored in the storage chamber 14, and it is possible to maintain a uniform temperature in each of the spaces above and below the storage chamber 14.

It also has an upper heating section 15b3 that heats the air in the space above the storage chamber 14, and a lower heating section 15b2 that heats the air in the space below.

This makes it possible to maintain the upper and lower spaces of the storage room 14 at the set temperature even if the temperature of the location where the storage facility 1 is installed is lower than the set temperature of the storage room 14.

The partition member 30 is also detachable from the storage chamber 14, and by removing the partition member 30 from the storage chamber 14, the inside of the storage chamber 14 can be maintained at a uniform temperature.

This makes it possible to increase the amount of items that can be stored in the storage chamber 14 when only items with one type of storage temperature are stored in the storage chamber 14, making it possible to make effective use of the space in the storage chamber 14.

In the above embodiment, a storage facility 1 is shown in which the storage chamber 14 is divided by a partition member 30 to form two spaces aligned vertically, but the present invention is not limited to this. For example, the present invention can be applied to a storage facility that divides the storage chamber in the width direction, as long as the storage chamber is divided in a direction perpendicular to the front-to-rear direction to form multiple spaces. In addition, the present invention can be applied to a storage facility that divides the storage chamber into three or more spaces, as long as the storage chamber is divided into multiple spaces.

In addition, in the above embodiment, a cooler 15c5 is disposed in the space above the storage chamber 14, and the air from the space above the storage chamber 14 is caused to flow into the space below via the door duct 22. However, this is not limited to this. For example, the present invention can be applied to a storage chamber in which a cooler is disposed in the space below the storage chamber, and the air from the space below the storage chamber is caused to flow into the space above via the door duct.

In addition, in the above embodiment, the storage facility 1 is shown in which the partition member 30 is attached to the attachment portion 14b provided at a predetermined position in the vertical direction of the storage chamber 14, but this is not limited to this. For example, the partition member may be attached at any height position within the storage chamber, and the size of the upper and lower spaces of the storage chamber may be adjusted as necessary. In this case, the lower end of the door duct may be extended to a position lower than the lowest position at which the partition member can be attached.

In the above embodiment, the positioning of the stored food containers is performed by the vertically extending protrusions 14a, 23 in the storage chamber 14, but this is not limited to this. For example, without providing the protrusions 14a, 23 shown in the above embodiment, a recess into which the bottom of the food container fits may be formed on the bottom plate of the storage chamber and the upper surface of the partition member, and the bottommost food container may be fitted into the recess to perform positioning of the entire stack of food containers.
