Description

DETAILED DESCRIPTION OF THE INVENTION [Field] The present invention relates to a refrigerated/heated storage device that can perform refrigeration and heating at the same time.

[Prior Art] Advances in science and technology and people's desire for a comfortable life have led to the emergence of new products called cold storages that combine refrigeration and heating functions into one unit.

By the way, modern people who live in air-conditioned homes or vehicles do not necessarily want warm food and drinks just because it is cold; for example, they may want to eat ice cream. It is not surprising that in situations where a large number of people participate in singing together, there are even more conflicting demands. Therefore, the plan is to either use both a refrigerator and a hot storage, or prepare two cold and hot storage units and use them separately for refrigeration and hot storage, but this is not economical in terms of storage space. It is no longer a good idea.

This is even more true if the vehicle is to be mounted on a private car.

There is still no refrigerated refrigerator that can perform both refrigeration and heating functions in one unit.

[Object of the Invention] An object of the present invention is to provide a cold/warm storage that can perform the functions of refrigeration and heating at the same time.

[Structure of the Invention] The cold storage of the present invention includes a cooler, a heater, and an air circulation fan installed in each compartment of an insulating container that is divided into two compartments by an insulating partition wall. The configuration is such that all or only part of these evaporators and 7+[l heating units are selectively operated.

According to a preferred embodiment of the invention, the 111i thermal compartment wall can be repositioned within the container and can function as a refrigerated or hot storage compartment when removed. It also includes an electric circuit and a control panel for controlling the functions of the cooler, heater, and air circulation fan to maintain the inside of the container within a predetermined temperature range.

[Effects of the Invention] The cold storage having the above configuration has the following effects.

B) When serving food and drinks in an air-conditioned room or in a vehicle, even if there are conflicting demands for hot and cold food, the present invention's refrigerator can be used as a single refrigerator. can meet this need, and is particularly suitable for in-vehicle use.

By removing the partition walls of the insulated container and operating only one of the coolers or heaters, the refrigerating machine can be used as a heating-only machine and the internal volume of the container can be fully utilized.

c) Since two coolers and two heaters are each incorporated, the number of them used can be increased or decreased to achieve a different cooling or heating temperature for the contents of the container.

[Example] Next, the cold storage of the present invention is shown in the figure.
explain.

In FIG. 1 as a cross-sectional view of the cold storage of the present invention,
The inside of the heat-insulating container 1 made of hard synthetic resin and having a double-walled structure filled with heat-insulating material such as styrofoam is as follows.
A heat insulating structure similar to the container can be divided into two compartments ΔJ3 and B by means of b insulating compartment walls 2.

This heat-insulating partition wall 2 has grooves 1a and 1b provided in the inner wall surface of one phase facing each other of the heat-insulating container 1.
152 It is possible to fit 1 in the container, and by fitting it into which groove, you can change the volume ratio of the A113 two compartments, and by removing the compartment wall 2, the entire inside of the container can be made into one compartment. It can also be used as It should be noted that if gaskets such as foamed rubber are bonded to both end faces of the heat insulating partition wall 20, the function of the above-mentioned fitting groove can be replaced.

The compartments A and B are provided with evaporators 3 and 4, heaters 5 and 6, and fans 7 J5 and 8 for circulating air within the compartments, respectively. C is the container contents. One fan motor is sufficient.

Next, to explain how to use the refrigerated and hot storage 1jif with the above-mentioned structure, when you want to perform both refrigerating and heating at the same time, which is the original usage state, the insulating partition wall 2 is used as described above to keep the contents of the container It'll be installed in an appropriate position depending on the amount of material C, and only the evaporator 3 will be installed in one compartment, and only the heater 6 will be installed in the other compartment B.

By operating the air circulation fans 7 and 8 in B, cold food and wet food can be served at the same time.
Wear. In addition, if you want to fully utilize the space inside the container for the purpose of only refrigeration or only heating, you can remove the insulating partition wall 2 and install two evaporators to increase the cooling capacity or to increase the heating capacity. The heaters 3 and 4 or the two heaters 5 and 6 are operated together. The evaporator is supplied with liquefied refrigerant from an external refrigerator. As the heater, an electric resistance heating element such as a ceramic electric resistor or a dichrome wire is suitable.

FIG. 2 shows an operational system diagram of the components related to the refrigeration function of the vehicle-mounted cold/hot storage of the present invention.

The refrigerant compressed by the compressor operated by the rotational force of the engine transmitted via the magnetic clutch 30 is liquefied to condensation "aE" and stored in the liquid receiver F, and is also used to cool the passenger compartment. For evaporator I [~tub valve G]
-C is sent through the expansion valve H to cool the evaporator I as a heat exchanger.

On the other hand, two sets of refrigerant passages for cooling the refrigerator are provided in parallel with this refrigerant passage for cooling the vehicle interior, and supply cooling refrigerant to the evaporators 3 and 4, respectively. Refrigerant flow control valves 15a3 and 16 and constant pressure expansion valves 17 and 18 are interposed in each cold storage flow path, and a check valve 1 is provided in the refrigerant return path of the evaporator 4.
9 and 20 respectively.

In the above embodiment (13), an evaporator that is cooled by diverting a part of the refrigerant supplied from a refrigerator for cooling the vehicle interior to a cold IJI device in the refrigerator is used. A thermal 7I element such as a Beltier element can be used as a cooler, and in this case, the heat-absorbing side and heat-generating side of the Beltier element can be used at the same time. If you replace it with a part of the partition wall, +111- heat generating elements will be used (
], it is possible to cool one compartment and heat the other compartment at the same time, which is a good method from the viewpoint of efficiently utilizing the scarce energy of the vehicle's power supply.

FIG. 3 shows an electric circuit diagram for operating the cold/hot storage of the present invention.

This is a switch for heating and OFF modes, each of which can be operated independently. 11 and 12 are two compartments A and J:
13 and 14 are pressure switches that operate by sensing the pressure of evaporators 3 and 4,
