Description

[Detailed description of the invention] This invention relates to a refrigerator.

In the chain system of the restaurant industry that handles hamburgers, sushi, ramen, etc., ingredients are pre-cooked in the central kitchen and stored at low temperatures, and the pre-cooked items are delivered to each chain restaurant in response to orders. Here, it is stored at low temperature and subjected to final cooking when necessary. Furthermore, at supermarkets, purchased frozen foods are stored in large freezers and refrigerators at distribution centers, and are delivered to each store as needed. In such cases, the delivery source such as the central kitchen and the delivery destination of the chain store will be
Each requires a large refrigerator-freezer, and a dedicated refrigerated truck to transport boxed frozen foods from the delivery source to the delivery destination. As a result, equipment costs increased, leading to higher product costs. The present invention was made in view of the above-mentioned circumstances, and an object of the present invention is to provide a refrigerator that can be used cost-effectively in the above-mentioned delivery system.

The refrigerator according to the present invention includes a refrigerator main body made of a heat insulating wall and having an opening for connecting a refrigeration unit at a predetermined position, and a refrigeration unit detachably attached to the main body.

Hereinafter, the present invention will be specifically explained with reference to illustrated embodiments.

1 and 2, the refrigerator according to the present invention consists of a vertically rectangular parallelepiped refrigerator body (2) made of a heat insulating wall (1), and a refrigeration unit (2) detachably attached to the refrigerator body (2).

As shown in Figure 2, the heat insulating wall (1) consists of a double structure wall (3) made of a pair of inner and outer plates such as aluminum plates, steel plates, synthetic resin plates, etc. It consists of a heat insulating layer (4) formed by injecting and foaming foamable urethane inside. A storage opening (5) is provided on the front wall of the refrigerator body (2),
The top wall is also provided with an opening (6) for connecting the refrigeration unit. These openings +51 and +61 are the single-opening heat insulating doors +7 installed on the front wall and top wall, respectively.
It is designed to be sealed by 1 +81. The structure of the heat insulating door +71 +81 is also the same as the structure of the heat insulating wall (1), and consists of a double wall and a heat insulating layer inside the wall. Casters (9) are attached to the bottom wall of the refrigerator body (2), and an insulated door (8) is installed to ensure cold storage during delivery.
A refrigerant filling bag fil is attached to the inner surface of the holder. Furthermore, OD
is a gasket, and α-ri Q31 is a hinge.

1 Refrigeration unit, as shown in FIGS. 1 and 4, is attached to the vertical support C311 of the lift (5) so as to be able to move up and down, and is suspended by wires (2) on both sides of the rear end. The wire is connected to the upper roller and the lower roller through a plurality of links. The height of the refrigeration unit (2) can be adjusted up and down by operating the pedal.

The refrigerator constructed in this manner is used, for example, as shown in FIG. 3. In other words, the central kitchen (
The pre-cooked items @ cooked in step 21) and stored in the large freezer-refrigerator ■ are stored in the refrigerator body (2) for each chain store. And this refrigerator body (2) is truck C! 4
and transport it to each chain store. Many chain stores are equipped with refrigeration units■. These can be moved up and down by a lift, making the height adjustable.

Therefore, place the refrigerator body (2) taken down from the truck (to) under the refrigeration unit (1), open its opening (6), and make sure that the cooler mounting part of the unit fits tightly into the opening (6). Lower the refrigeration unit ■ so that the The cooler attachment part (■) is made of a heat insulating material, and the cooler (4) attached to it faces the inside of the refrigerator body (2). In this way, the refrigeration unit (2) is connected to the refrigerator main body (2). In this state, the pre-cooked food (c) is stored at a low temperature at the chain store (2), and if necessary, it is taken out of the refrigerator body (2) and subjected to final cooking. Another empty refrigerator body (2)
will be forwarded to the central kitchen (211).
There are also large freezers (2) in the central kitchen I21).
Alternatively, a refrigeration unit may be installed.

In this case, there will be a significant advantage in terms of equipment costs.

5 and 6 show a second embodiment of the refrigerator according to the present invention. In this example, an opening (4υ) for connecting the refrigeration unit and its door (4η) are provided on the rear wall.
It is provided at the required height position of 3. Then, the refrigerator body is connected to the refrigeration unit @ by pushing it backward so that the front protruding cooler attachment part (a of 47J) fits tightly into the opening of the refrigerator body. Ru.

The cooler is attached to the part (the machine is also made of heat insulating material, and the cooler attached to this part faces the inside of the refrigerator body (441).Other symbols are the same as the members with the same symbols in the first embodiment. shows.

FIG. 7 shows a third embodiment of the refrigerator according to the present invention. In this example, the corner portions between the side walls of the rectangular parallelepiped refrigerator body +51+ are chamfered. And each of the removal parts ω is attached with a stay cover. In this case, the stay (to) is the refrigerator body 51) as shown in FIG.
The refrigerator bodies (51) are placed in close contact with each other when loaded onto a truck.The stay ω is , used as a handle when moving containers,
It is used as an engagement member when hoisting with a crane, and also functions as a protection member against collisions.

As described above, the refrigerator according to the present invention includes a refrigerator main body having an opening for connecting the refrigeration unit at a predetermined position, and a refrigeration unit that is detachably attached to the main body, so that the refrigerator main body or the refrigeration unit may deteriorate in function. In the event of damage or damage, you only need to replace the defective one with a new one, and the non-defective one can be used as is, which greatly reduces equipment costs. can be taken as a thing.
