Description

[Detailed explanation of the idea] The present invention relates to an automobile refrigerator.

Conventional refrigerators, that is, boxes with functions such as refrigeration, freezing, and heating, use the cold air from an air-conditioning evaporator inside the vehicle, and those that take the cold heat from the air-conditioning evaporator into the box via a heat transfer plate. Alternatively, it has been proposed to have a separate evaporator for the refrigerator that is branched from the main air conditioning system and perform refrigeration, etc., but both are fixed to the vehicle, so the box must be taken out of the vehicle. That is impossible.

In addition, refrigerators that have a dedicated compressor and heat exchanger and allow the box to be taken out of the vehicle have also been put into practical use, but this type of refrigerator also has a power source for the components and drive. Because they must be built-in, they are generally disadvantageous in terms of size and weight.

The present invention was proposed in view of the above circumstances, and an object of the present invention is to provide an automobile refrigerator that can be taken out of the vehicle when necessary.

To this end, the present invention provides a refrigerator evaporator branching and protruding from a refrigerant circuit for vehicle air conditioning, a portable heat-insulating box having an evaporator insertion hole for inserting the refrigerator evaporator, and the refrigerator evaporator and the portable insulating box. The present invention is characterized by comprising a guide member that guides the heat insulating box relatively to the evaporator insertion hole.

An embodiment of the present invention will be explained with reference to the drawings.
Figure 1 is a perspective view of the refrigerator, Figure 2 is a side view showing how to insert the refrigerator in Figure 1 into the evaporator in the passenger compartment, Figure 3 is a perspective view of the evaporator in Figure 2, and Figure 4 is a side view showing how to insert the refrigerator in Figure 1 into the evaporator in the passenger compartment. Figure 2 is a vertical cross-sectional view showing the refrigerator inserted into the evaporator, and Figure 5 is the 4th cross-sectional view.
6 is a longitudinal sectional view showing a modification of FIG. 4, and FIG. 7 is a plan view of FIG. 6.

First, in FIGS. 1 to 5, 1 is the portable refrigerator body (hereinafter referred to as the main body) according to the present invention, 2 is the upper lid,
3 is a side cover for opening and closing the evaporator insertion port provided at the front lower part of the main body 1, 4 is a shoulder belt, 5 is an evaporator dedicated to the main body that is attached to the in-vehicle cooling system, and 5-1 is a plurality of internal U-shaped flat extruded material tube having a refrigerant flow path, 5
-2 is a refrigerant collection header, 5-3 is a joint connected to the automobile air conditioning system, 6 is a grating board that partitions the upper part of the evaporator insertion hole of the main body 1, and 7 is fitted into the lower end opening of the valley-shaped bottom surface of the evaporator insertion hole. 8 is an object to be cooled inserted into the main body 1; 9 is a movable cover attached to the car side and surrounds the evaporator 5; 10 is a movable cover provided at the base end of the evaporator 5, and the main body 1 is inserted into the evaporator 5. A sealing member 11 is provided in the lower part of both sides of the main body 1 and extends horizontally, and a sealing member 12 is provided on the vehicle body side and is large enough to cover the entire surface of the evaporator 5. The guide 12a at the upper end of the drain tray is connected to the main body 1.
is inserted into the guide groove 11 of.

In such a structure, the main body 1 is inserted into the evaporator 5 along the guide 12a with the side cover 3 opened, as shown in FIG.

Then, since the evaporator insertion opening comes into airtight contact with the sealing member 10, the object 8 to be cooled inside the main body 1 is cooled by the evaporator 5, so the upper cover 2 can be opened and the object 8 to be cooled can be taken out if necessary. can.

Next, when it becomes necessary to take the refrigerator out of the vehicle, as shown in Figure 2, just pull out the main body 1, and the evaporator 5 is fixed to the vehicle side, so the main body 1 can be separated. , Close the side lid 3 to prevent cold air from escaping.

Then, the space where the evaporator 5 was previously housed serves as an air insulation layer and promotes the heat insulation effect, so the object to be cooled 8 can be taken out of the vehicle while maintaining its cooling.

Further, since there is a shoulder belt 4, it is easy to carry, and the drain generated can be drained by pulling out the drain plug 7 at a suitable time.

When inserting the main body 1 into and separating it from the evaporator 5, as shown in FIG. 2, by aligning the tip of the guide groove 11 with the guide 12a, the position where the evaporator 5 is stored is determined, and the In this state, it can be smoothly installed in the direction of the arrow, preventing excessive force from being applied to the evaporator 5, increasing its reliability, and facilitating installation and removal.

In addition, the main body and guide (drain pan) can be installed in a vehicle.
A sense of stability is achieved by firmly holding the structure, and it can withstand severe vibration conditions. Further, since the guide also serves as a drain tray, there is an effect that the drain generated in the evaporator 5 can be recovered.

Next, in the structure shown in FIGS. 6 and 7, the evaporator 25 is made vertically movable, and when inserted in the direction of the arrow, the guide 2 provided on the main body 21
0, it can be easily stored.

The present invention can be applied not only as a refrigerator but also as a hot and cold refrigerator.

In short, according to the present invention, there is provided a refrigerator evaporator branching and protruding from a refrigerant circuit for vehicle air conditioning, a portable heat-insulating box having an evaporator insertion hole for inserting the refrigerator evaporator, and the refrigerator evaporator and the refrigerator evaporator. The present invention is industrially extremely useful because it provides a portable refrigerator for automobiles by including a guide member that relatively guides the transport heat-insulating box in the direction of the evaporator insertion hole.
