Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mounting device for a thermosensitive cover used in a direct cooling type cooling system such as a refrigerator or a 7-yaw case.

BACKGROUND OF THE INVENTION A mounting device for a thermo-sensitive cover used in a conventional refrigerator will be described with reference to FIGS. 3 and 4.

1 is the main body of the refrigerator, which includes an outer box 2, an inner box 3 for the upper chamber, an inner box 4 for the lower chamber, and a foam insulation material 6 filled between each box 2, 3.4.
It becomes more. And, what about the inner box 3 for the upper chamber as a freezer compartment, and the inner box 4 for the lower chamber? ! It is used as a 4R storage room. Reference numeral 6 denotes a refrigerant pipe that snakes vertically on the back side of the inner box 4 forming the refrigerating room. Although not shown, this refrigerant vibro is attached to the inner box 4 with aluminum foil tape. 7 is a thermostat that controls the temperature of the inner box 4 forming the refrigerator compartment;
It controls the operation of the compressor 8 located at the bottom of the. Reference numeral 9 denotes a pair of concave grooves located on the back wall of the inner box 4, sandwiching the refrigerant pipe e, and the grooves widen toward each other. A protrusion 11 is formed in each portion 1o sandwiched by the groove 9. 12 is a cover for installing the thermo sensitive part,
Made of synthetic resin. This cover 12 has a claw 13 that is inserted into the groove 9 and engages with the protrusion 11 .

Moreover, seven flange 14 for cosmetic use protrudes from the cover 12 toward the inner box 4 so that the groove 9 is not visible.

Reference numeral 16 denotes a thermosensitive part of the thermostand 7, which is inserted into the hollow PVC pipe 16. And this PVC pipe 16
is pressed against the cover 12 via an elastic material 17 so as to be along the refrigerant vibro at a portion 1Q sandwiched by the groove 9.

In such a device, the PVC pipe 16 transmits the temperature of the refrigerant vibro to the thermosensitive section 16 via the inner box 4.

Problems to be Solved by the Invention However, in the conventional structure, in order to adjust the variation in heat-sensitive temperature, first the thickness of the PVC pipe 16 is replaced with a separately prepared one, and in response to this, the thickness of the elastic material 1T is changed. It was also necessary to change the thickness so that the PVC pipe 16 could reliably absorb the temperature changes of the refrigerant vibro. therefore,
This was a time-consuming task as it required at least two parts to be selected. Also, during installation work, the thermo tube heating section 16
The cover 12 had to be fitted into the inner box 4 while holding the handle, resulting in poor workability.

The present invention aims to eliminate the conventional problems, reduce the number of parts, and improve installation workability.

Means for Solving the Problems In order to achieve the above object, the present invention temporarily fixes the heat-sensitive part of the thermostat to the cover via a spacer, and sometimes attaches the cover to the inner box by releasing the temporary fixing and then inserting the cover. It is pressed against the box through a spacer, and the operating temperature is adjusted only by the thickness of the spacer.

Function: Therefore, according to the present invention, when adjusting the heat-sensitive temperature, it is only necessary to replace the spacer.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2. Structures that are the same as those of the prior art will be given the same reference numerals, and detailed explanation thereof will be omitted.

In the figure, 18 is a cover made of synthetic resin. A claw 19 that is inserted into the groove 9 of the inner box 4 and engages with the protrusion 11 extends from the cover 18, and a nail 19 that is shorter than the nail 19 and is used for cosmetic purposes to prevent the groove 9 from being seen. 7 langes 20 are integrally formed. and,
The flange 20 is expanded at a raised abutting portion 21 of the inner box 4 located on the opposite side of the protrusion 11 of the groove 9. A pair of support pieces 22 extend from the cover 18 and are located closer to the center than the claws 19. The cover 18 is placed between the pair of support pieces 22 in the recess m9 of the inner box 4.
A spacer 23 is attached to the spacer 23, which is temporarily fixed before being attached to the spacer 23.

The supporting piece 22 is connected to the seven flange 2o by a decorative rib 24, and when the cover 18 is attached to the inner box 4 and the seven flange 2o expands at the contact portion 21, the supporting piece 22 also expands. It is something.

Further, a projection 26 having a groove 26 extends toward the inner box 4 at the center of the cover 18, and the thermosensitive part 16 is temporarily fixed by the groove 26 of the projection 26 and the spacer 23. When the cover 18 is attached to the inner box 4, the projection 26 presses the temperature sensing section 15 against the inner box 4 via the spacer 23.

The spacer 23 also serves as a temperature adjustment mechanism when transmitting the heat of the refrigerant vibro to the heat sensitive section 16 via the inner box 4.

In such a device, the heat-sensitive portion 16 is temporarily fixed to the cover 18 and is attached to the groove 9 of the inner box 4, so that work efficiency is improved. Further, variations in temperature sensing can be resolved by simply changing the thickness of the spacer 23, and only one component is required, improving work efficiency. Further, since the spacer 23 is temporarily fixed to the cover 18 by being sandwiched between the support pieces 22, even if the thickness of the spacer changes, it will not affect the installation work in any way.

Effects of the Invention As is clear from the embodiments described above, in the present invention, the temperature sensing portion is temporarily fixed to the cover using a spacer, so that the cover can be easily attached to the groove of the inner box with one hand. Further, since the spacer is temporarily fixed by being sandwiched between the supporting pieces of the cover, it can be held even if the thickness of the spacer is changed to eliminate temperature sensitivity variations, so that workability is not affected. Also,
This allows the number of parts to be reduced.
