Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a freezing and refrigerating device that facilitates highly accurate control of the temperature within a product storage box.

(Conventional wave 1j and its problems) Conventionally, in order to make it easier to control the temperature inside the product storage area with high precision, for example, a plyine cooled by a refrigeration device was pumped into the sealed space of the box body containing the product storage box. This is intended to cool the inside of the product storage box. There is also a system in which seven plines are placed in advance in the sealed space, and the evaporator of the refrigeration system is immersed in the plines to cool the inside of the product storage box.

However, in the case of the above-mentioned prine type, the entire apparatus is complicated, has a complicated construction, is heavy, and has difficulty in portability9, and furthermore, the rapid operation efficiency of the refrigeration apparatus is poor.

(Purpose of the Invention) Therefore, the present invention aims to cool the inside of the product storage box by providing an evaporator in the closed space without using a pline, and circulating the air cooled by the evaporator in the closed space with a blower. In addition to solving the problem with the Pline type mentioned above, the opening/closing door of the product storage box is made hollow and this hollow part is communicated with the sealed space to prevent heat from entering through the opening/closing door, Product storage j′
The purpose is to provide a freezing and refrigerating device with good cooling effect within h.

(Detailed Description of the Invention) This invention provides a product storage box in an internal sealed space of a box body, cools the air in the sealed space with an evaporator provided in the sealed space, and circulates this cold air with a blower. It cools the inside of the product storage box, and the opening/closing door of the product storage box is hollow, and this hollow part is connected to the closed space.
It completely prevents the intrusion of heat from the opening/closing door by allowing cold air to flow inside the opening/closing door.

(Example) 1 is a box body with a closed space S inside, 1a is the front wall, 1b is the rear wall, 1C is the bottom wall, and 1d is the top wall.

A cask 2 is provided at the bottom of the box body 1.

3 (C) The front surface is formed as an opening 3a, and this opening 3
a to the outside from the front wall 1a, and the opening 3
The part other than a is a product storage box that exists in the closed space S. In the embodiment, the storage boxes 3 are provided in four stages spaced apart from each other vertically, and an opening/closing door 4 is vertically supported 4a on the front surface of each storage box 3. That is, the opening/closing door 4 is fitted onto a shaft 4a protruding from the storage box 3. Each door 4 is hollow inside 4b
each hollow part 41) is formed as a flexible tube 5
It is also in communication with the closed space S through the 1Ifi path 1e provided in the front wall 1a.

6 is a large door with a vertical pivot 6a on the front of the box body 1;
A space is provided with respect to the front wall 1a. The large door 6 has a heat insulating groove.

The box is a refrigeration unit and is installed on the box body 1. 7
8 is an expansion valve thereof, and 8 is an evaporator, both of which are provided in a closed space S. In this embodiment, the evaporator 8 is mounted on the rear wall 1b.

Reference numeral 9 denotes a blower (a cross-flow fan in the embodiment), which is provided below the evaporator 8 at the intersection of the rear wall 11] and the bottom wall 1C. The rotation axis of the air blower 9 is in the left-right direction, and the suction port 9a is opened forward and the discharge port 9b is opened upward.

Part 10 is a partition plate provided between both side walls of the box body 1 and the rear end of the storage box 3, which partitions the space on both sides of the storage box 30 from the rear space.

Reference numeral 11 denotes a case containing a desiccant, which can be inserted into and taken out from the side wall of the box body 1 into the sealed space S. This embodiment case 11 is equipped with a known means for checking the moisture absorption of the desiccant.

Furthermore, the operation of this embodiment will be described.

When the UNISO) R and the blower 9 are operated, the air in the closed space S is cooled by the evaporator 8, and this cold air is transferred to the rear wall 1b.
, and further passes through the space between the upper wall 1d and the uppermost storage box 3, and between adjacent storage boxes 3, and further descends along both side walls of the box body 1. It is done.

Therefore, the circulating cold air evenly contacts the outer surfaces of the storage boxes 3 existing in the space S, so that the cold air can be efficiently and quickly removed from the storage boxes 3.
It is possible to cool the inside.

Furthermore, a part of the circulating cold air is passed through the passage 1C.

It is also guided through the tube 5 to the hollow part 4b of the opening/closing door s4, suppressing the intrusion of heat from the opening/closing door 4, and further improving the cooling effect inside the storage box 3.

Note that since the space S is sealed, moisture hardly enters from the outside. If moisture gets in,
The airtight space S is dehumidified by the desiccant in the case 11.
There is little chance of frost formation, and defrosting is not necessary.

The above description is an example, and the hollow part 4 and the closed space n51S
For example, the flexible tube 5 may be completely eliminated and the shaft 4a may be used as a hollow shaft, and the hollow portion thereof may be communicated with the passage 1e and the hollow portion 4b. It goes without saying that the technical scope of the present invention also includes the replacement of each component with equivalents.

(Effects of the Invention) As described above, this invention cools the air in the closed space S and forcibly circulates this cold air to cool the inside of the storage box 3, which is different from the conventional prine type. Compared to 011, the entire device is compact, easy to manufacture, lightweight and easy to transport, and the speed and efficiency of the refrigeration device is also improved. Furthermore, since a part of the air in the sealed space 8 is guided into the hollow part 4b of the opening/closing door 4, the cooling inside the storage box 3 is improved compared to a case where the opening/closing door 4 is simply a heat insulating groove. Becomes good.
