Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an underfloor storage device having a storage compartment equipped with a freezer.

[Prior Art] An underfloor storage device is a storage unit equipped with a freezer installed under the floor, and its use in homes has been expanding in recent years as it makes effective use of three-dimensional space.

A conventional underfloor storage device is disclosed in Japanese Patent Application Laid-Open No. 60-21597, for example.
As proposed in Publication No. 4, a plurality of storage compartments were stored in a storage room that was sealed under the floor except for the opening in the floor surface.

The conventional underfloor storage device as described above will be described below with reference to the drawings.

FIG. 2 is a side sectional view of a conventional underfloor storage installed under the floor.

In FIG. 2, 1 is a floor surface, and 2 is a storage room.

The storage room 2 is provided under the floor and is surrounded by a wall surface 3. 4
is an opening, which is provided on the floor surface 1, and has a plurality of storage compartments 6 with refrigerators 5a and 5b attached on both sides below the opening 4.
a and 6b are placed stationary on fixed stands 7a and 7b. Note that both refrigerators 5a and 5b are collectively referred to as refrigerator 5. The storages 6a and 6b can be moved horizontally and vertically within the storage chamber 2 by a lifting device 8. Reference numeral 9 denotes a door attached to the opening 4 on the floor 1, and the door 9 is attached to the opening 4 on the floor 1.
Opens and closes in conjunction with the vertical movement of.

Next, FIG. 3 is a diagram illustrating the basic principle of the refrigerator 5 used in the prior art. In FIG. 3, 15 is an electric motor for driving a compressor 16, 16 is a compressor for adiabatically compressing a refrigerant such as fluorocarbon gas, and 17 is a compressor that takes heat from the storage compartments 6a, 6b, etc. to lower the surrounding temperature. 18 is an expansion valve for adiabatically expanding a cooling medium such as freon gas, and 19 is a condenser for discharging the heat absorbed by the evaporator 17.

The operation of the refrigerator having the above configuration will be explained below.

A compressor 16 is driven by an electric motor 15, and a cooling medium such as fluorocarbon gas undergoes adiabatic compression. The cooling medium moves in a cooled state to the evaporator 17, where it evaporates to keep the surroundings at a low temperature. The cooling medium then moves to the expansion valve 18 and expands adiabatically. The cooling medium then passes to the condenser 19 and releases the absorbed heat.

The underfloor storage of the underfloor storage device with the above configuration has a structure in which the exhaust heat of the refrigerator is trapped in the storage chamber and is exhausted at least when the elevating device is moved or when the door is opened and closed.

[Problems to be Solved by the Invention] However, in the underfloor storage of the conventional underfloor storage device, the exhaust heat of the refrigerator 5 is trapped in the storage chamber 2, and the heat cannot be efficiently exhausted, resulting in long-term problems. However, there was a problem in that food could not be stored stably.

The reason for this is that, as explained in FIG. 3 above, the condenser 19 becomes a heating element, and this waste heat is trapped in the storage chamber, and the electric motor 15 for driving the compressor 16 also tends to generate heat. .

In order to solve the problems of the conventional underfloor storage device, the present invention provides an intake port and an exhaust port at specific positions on the wall surface of the storage chamber, prevents waste heat from being trapped in the storage chamber, and provides stable food storage for a long period of time. The purpose of the present invention is to provide an underfloor storage device that allows for storage.

[Means for Solving the Problems] In order to achieve the above object, the underfloor storage device of the present invention is an underfloor storage device including a plurality of storage compartments each equipped with a refrigerator in a storage chamber formed under the floor surface. At least two of the plurality of refrigerators are arranged on the side wall side of the storage chamber, and an intake port is provided on the side wall of the chamber near the one refrigerator, and the air intake port is provided in the side wall of the chamber near the one refrigerator, and It is characterized by an exhaust port provided on the side wall.

In the configuration of the present invention, it is preferable that at least two refrigerators disposed on the side wall side be disposed at opposing positions when viewed from the front cross-sectional direction.

[Function] According to the configuration of the present invention described above, since the refrigerators are installed in the rooms near the intake port and the exhaust port, there is a large amount of waste heat vs. flow rate, and the heat radiation efficiency of the storage and the storage room is increased. be able to. The reason for this is that if an intake or exhaust port is provided near the refrigerator, which is easy to heat, the wind speed can be increased and heat exchange can be facilitated. As a result, it is possible to provide an underfloor storage device that lowers the temperature inside the storage room and enables long-term stable storage of food in the storage.

Furthermore, according to the configuration of the present invention in which at least two refrigerators placed on the side wall side are placed in opposing positions when viewed from the front cross-sectional direction, abnormal retention of heated air can be prevented, and heat exchange as a whole can be achieved. can be done efficiently.

[Example code] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

It is preferable that the sizes of the intake port 10 and the exhaust port 11 are each 400 cnf or more. The fan 12 may be provided at each of the intake port 10 and the exhaust port 11, or may be provided only at the exhaust port 11. Since the exhaust fan 12 is located under the floor, it is undesirable to make the rotation speed too high from the viewpoint of noise generation, and it is preferable to set the rotation speed to the same level or lower than that of the exhaust fan of a ventilation fan used in a home kitchen. In addition, the intake port 10 and the exhaust port 1
A duct 13 is provided in each of the refrigerators 5a and 5b.
Alternatively, a fluid with a high flow rate may be applied to. This is to efficiently exchange heat.

As described above, according to the configuration of this embodiment, the refrigerator 5a in the storage 6a facing the intake port 10 and the refrigerator 5b in the storage 6b facing the exhaust port 11 are efficiently cooled by intake and exhaust convection. , the heat radiation efficiency of the refrigerator 5 can be improved,
In addition, the temperature in the storage room can be lowered, and food in the storage can be stored stably over a long period of time.

Note that heat is likely to be generated mainly when the compressor (FIG. 3) is in operation, so in the present invention, the fans of the intake port 10 and/or the exhaust port 11 are operated in conjunction with the operation of the compressor. It may be rotated.

[Effects of the Invention] As explained above, according to the present invention, at least two of the plurality of refrigerators are arranged on the side wall side of the storage chamber, and an air intake port is provided on the side wall of the chamber near the one refrigerator. In addition, by providing an exhaust port on the side wall of the chamber near the other refrigerator, the flow rate of exhaust heat is large, increasing the heat dissipation efficiency of the storage and storage room, and lowering the temperature inside the storage room. , it is possible to achieve the excellent effect of enabling long-term stable storage of food in the storage.

Further, according to the preferred device of the present invention in which at least two refrigerators arranged on the side wall side are arranged at opposing positions when viewed from the front cross-sectional direction, abnormal retention of heated air can be prevented, and the overall heat is reduced. The excellent effect of being able to perform exchange efficiently can be achieved.
