Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides that when an absorber absorbs refrigerant, in an evaporator,
This relates to a refrigerator that utilizes the cooling effect of refrigerant that evaporates and absorbs the latent heat of evaporation from the surrounding area. 1. Conventional configurations and their problems Among the conventional portable refrigerators, the most widely put into practical use is the no. This is an ice box used for eking and fishing. This is a method in which ice or latent heat type cold storage material, which has been previously stored in an electric refrigerator or the like, is placed inside an insulated box to keep the inside of the refrigerator cold for about - days. The problem is that the cold storage energy density of ice and the cold storage material is 30 to 5 ol.
It is within the range of cal/Ky, and is quite large, so a large amount is still required.

In addition, since these cold storage materials are placed inside the refrigerator, the inside of the refrigerator becomes cluttered, and the ice melts and water accumulates inside the refrigerator.

OBJECTS OF THE INVENTION The object of the present invention is to provide a lightweight, easy-to-handle, and quiet-operating refrigerator that utilizes the heat involved in chemical reactions with high cold storage density.

Structure of the Invention The structure of the present invention is such that an evaporator/condenser constituting a chemical heat pump unit that can be attached or detached in the refrigerator is brought into thermal contact with the bottom surface of the inner container, and the evaporator/condenser and the chemical heat pump A heat insulating material is placed between the absorber and generator that makes up the system. With.

This is a refrigerator that can be connected via a valve to easily store cold heat.

DESCRIPTION OF EMBODIMENTS The present invention allows an intermittent chemical heat pump unit to be detachably attached to a refrigerator body, and embodiments will be described below with reference to the drawings. Chemical heat pump unit 2, an absorber that absorbs refrigerant in the absorber/generator 4,
A heat insulating material 8 is arranged between the absorber/generator and the evaporator/condenser, and the evaporator/condenser 7 is connected to the absorber/generator 4 via a valve 6 via a pipe 5. Both containers were connected to each other and both containers were brought to a reduced pressure state by removing non-condensable gas.

FIG. 1 is a perspective view of a refrigerator according to an embodiment of the present invention, and FIG. 2 is a perspective view of an intermittent heat pump unit. --First, let's explain the charge. Remove the mounting bracket 1 and separate the intermittent heat pump unit 2 and main body 3. Then, the intermittent heat pump unit 2 is taken out. There, the absorber/generator 4 is heated to absorb the refrigerant, which evaporates the refrigerant absorbed in the material, which passes through the vibro and valve 6 to the evaporator/condenser 7.
It radiates heat and condenses into liquid. The heat of condensation at this time is released into the atmosphere.

When sufficient refrigerant evaporates from the absorber, valve 6 is closed and charging is completed.

After that, the main body 3 and the intermittent heat pump unit 2 are attached again with the four metal fittings 1, and when the valve 6 is opened, the refrigerant evaporates and cooling starts. FIG. 3 is a cross-sectional view of FIG. 1. When the refrigerant in the evaporator/condenser T evaporates and is cooled by taking evaporation heat from the surroundings, the internal container 9 that is in thermal contact with it is cooled. The air inside the refrigerator 10 is cooled. The internal container 9 is made of a fine material with good thermal conductivity. When charging, the absorber/generator 4 is heated and the evaporator/condenser 7 radiates heat, so it is separated from the main body 3. Further, a heat insulating material 8 is provided between the absorber/generator 4 and the evaporator/condenser 7 for thermal insulation.

The evaporator/condenser 7 is in thermal contact with the bottom of the internal container 9, and since the internal container 9 is made of a material with good thermal conductivity, the temperature of the internal container 9 is lower than that of the internal container 9. This has the advantage that the temperature of the bottom surface of the refrigerator is low, and the degree of gourability of canned juice or the like in the refrigerator interior 1o is lower than that of the interior 10 due to heat conduction from the bottom surface.

Note that the intermittent heat pump unit 2 is placed on the bottom surface of the refrigerator. In this case, it is not the best in terms of heat convection inside the refrigerator, but when integrated with an intermittent heat pump, it becomes a weight at the bottom, making it stable and easy to use. Therefore, the refrigerator body can be made of lightweight materials without considering usability.

Effects of the Invention In the present invention, 1f4 is absorbed and released by the absorbent material.
J. To provide a refrigerator that utilizes the cold energy of a chemical heat pump unit, which is easy to charge, allows the interior of the refrigerator to be widely used without putting an evaporation section in the refrigerator, and is further convenient to use.
