[Problem that the invention attempts to solve]

The conventional fixing structure of the temperature regulator fixture requires screws and fixing nuts for fixing, as well as sealing material for cold air leakage, and has problems such as a large number of parts and poor workability.

This idea was made to solve the above-mentioned problems, and aims to provide a fixing device that eliminates parts such as fixing parts and sealing materials, has good workability, and can ensure stable quality. purpose.

[Means for solving problems]

A fixing device for a temperature regulator of a refrigerator according to this invention divides the refrigerator main body into two compartments, a freezer compartment and a refrigerator compartment, using a middle partition part, and partitions a cooler compartment at the back of the freezer compartment with a fan grill. In this refrigerator, the cooler chamber is equipped with a cooler and a blower above the cooler, and the blower circulates cold air to the freezer compartment and the refrigerator compartment, respectively. A temperature regulator mounting fixture formed in the above-mentioned refrigerator compartment, a locking claw protruding from the back side of the fixture, and an engaging hole opened in the inner box corresponding to the locking claw, and an outlet of the cold air blowing air passage of the refrigerator compartment. The inner box corresponding to the back surface of the temperature regulator fitting is provided with a plurality of through holes into which the foamed heat insulating material enters.

[Effect]

In the refrigerator temperature regulator fixing device in this invention, a part of the foam insulation material enters the space on the back side of the temperature controller mounting fixture through the through hole of the inner box and fills it, so the adhesiveness of the insulation material The mounting fixture for the temperature regulator can be more firmly fixed, and the heat insulating material conventionally inserted into the space for insulating the space between the housing parts of the temperature regulator near the ventilation opening of the fixture can be omitted.

[Example of idea]

An embodiment of this invention will be described below.
In the drawings, parts that are the same as or equivalent to the conventional ones are given the same reference numerals and explanations are omitted. In FIGS. 1 and 2, 13 is a partition-cut heat material, 13i is an extension that hangs down from the outlet 13g of a cold air blowing passage 13h that opens to the partition-cut heat material, and 14 is a synthetic resin temperature controller. The above-mentioned extension part 13i is attached to the upper surface of the fixture of the container.
At the same time as inserting the outlet part 13g of the cold air outlet
An opening 14a for receiving cold air is provided. Further, a ventilation hole 14b corresponding to the damper portion 15a of the damper-type temperature regulator 15 is provided at the upper front surface of this fixture. Numerals 14d and 14e are a plurality of locking claws protruding from the back surface of the mounting plate 14f of this fixture. , which restricts movement in the vertical and horizontal directions when engaged. 2 is an inner box, and 2a and 2b are locking claws 14d and 1 protruding from the back surface of the mounting tool 14 in this inner box.
This is an engagement hole that opens corresponding to 4e.

Reference numeral 14g denotes a back plate of the cold air receiving opening 14a of the fixture 14, which protrudes slightly rearward from the surface of the mounting plate 14f. Then, when the fixture 14 is attached to the inner plate 3, a stepped portion formed by cutting out a part of the cut heat material 13 so that the inner surface of this back plate is flush with the inner surface of the cold air blowing air passage 13h is formed. This prevents cold air from entering the joint between the inner box 2 and the fixture 21.

14h is a housing portion for the damper type temperature regulator 15 formed below the ventilation port 14b of the fixture 14;
Reference numeral 14i denotes a space formed between this storage section and the ventilation port 21b, which prevents dew formation on the storage section 14h side. 2c is a through hole opened in the inner box 2 corresponding to this space, and when the foam insulation material is foamed and filled between the outer box 1 and the inner box 2, the insulation material enters the space 21h of the fixture through this through hole. It is supposed to be filled.

In the device configured as described above, first the locking claw 14e of the temperature regulator mounting tool 14 is engaged with the engagement hole 2b of the inner box 2, and then the locking claw 14d is fitted into the engagement hole 2a. The insertion fixture 14 is fixed to the inner box 2.
At this time, since the engaging holes 2a and 2b corresponding to the locking claws 14d and 14e are both opened to match the width of the locking claws, the fixture 14 can be fixed at a predetermined position with respect to the inner box 2. At the same time, vertical and horizontal movement is also restricted. Thereafter, the locking claws 14d and 14e are further firmly fixed by filling the space between the inner and outer boxes with a foamed heat insulating material 4 such as polyurethane foam.

In addition, a portion of the foam insulation material 4 is inserted into the through hole 2 of the inner box 2.
Since the space 14i on the back side of the fixture 14 is filled from c to the space 14i on the back side of the fixture 14, the fixture 14 of the temperature regulator is more firmly fixed due to the adhesiveness of the heat insulating material, and the fixture 14 of the temperature regulator is fixed even more firmly, and it is not close to the ventilation opening 14b of the fixture in the past. The heat insulating material inserted into the space 14i to insulate the space between the storage parts 14h of the temperature regulator 15 can be omitted.

[Effect of idea]

As described above, according to this invention, the refrigerator main body is divided into two compartments, a freezer compartment and a refrigerator compartment, using a partition part at the top and bottom, and a cooler compartment at the back of the freezer compartment is partitioned by a fan grill. In the refrigerator, the chamber is equipped with a cooler and a blower above the cooler, and the blower circulates cold air to the freezer compartment and the refrigerator compartment, in which the ventilation opening and the storage part for the damper type temperature controller are integrally formed. A temperature controller mounting fixture, a locking claw protruding from the back side of the fixture, and an engagement hole opened in the inner box corresponding to the locking claw, and the above-mentioned one is provided at the outlet of the cold air blowing air path of the refrigerator compartment. The fitting is engaged and fixed, and the inner box corresponding to the back side of the temperature regulator fitting is provided with a plurality of through holes through which the foam insulation material enters, so that after filling with the foam insulation material, The locking pawl is firmly fixed, and a portion of the foam insulation material enters the space on the back of the temperature controller mount through the through hole of the inner box and fills it, so the adhesiveness of the insulation material causes the temperature controller to The mounting bracket is more firmly fixed, and the insulating material that was conventionally inserted into the space between the temperature controller compartments near the ventilation opening of the fixture can be omitted, reducing the number of parts. It is possible to reduce this amount and improve workability.
