Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermostat or other attachment device that is attached to a cooler such as a refrigerator to detect the end of defrosting.

2. Description of the Related Art In recent years, coolers such as refrigerators have been defrosted by a heater after operating for a certain period of time, and a bimetal thermostat (hereinafter referred to as thermostat) is used to detect the end of defrosting.
Is used, and one example is
There are examples as described in −73688.

This example will be described below with reference to the drawings. In FIG. 7, 1 is a cooler. Reference numeral 12 is a thermostat housing, which has a cylindrical shape with a bottom and has a built-in bimetal thermostat. A heat sensitive cap 13 is made of a spring material such as stainless steel, and is attached so as to seal one end of the housing 12. Reference numerals 14 and 15 are hook-shaped bent portions, which are provided at both ends of the heat-sensitive cap 13.

In FIGS. 7 and 8, 16 and 17 are slits, which are formed in the cooler 1 and are fitted with hook-shaped bent portions 14 and 15 provided at both ends of the heat-sensitive cap 13.

A method of mounting the thermostat having the above structure will be described below. First, hook-shaped bent portions 14 and 15 provided at both ends of the thermostat cap 13 of the thermostat are press-fitted into the slits 16 and 17 provided in the cooler 1 in advance. At this time, since the hook-shaped bent portions 14 and 15 have a spring property, the thermostat can be pressed and fixed to the cooler 1 with a constant spring force.

SUMMARY OF THE INVENTION However, in the above-described conventional configuration, since the spring force presses and fixes, there is a problem that the worker comes off when touched.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above conventional problems and to provide a thermostat mounting device which is not easily removed after the thermostat is mounted on the cooler.

Means for Solving the Problems In order to achieve the above object, the present invention provides a mounting hole for a thermostat or the like provided in a central portion of a main body of a substantially U-shaped strip having spring properties, and both end portions of the main body. And an approximately L-shaped hooking portion, and a holding claw that is in the shape of a tongue that cuts and raises the substantially U-shaped main body on one side of the hooking portion and that abuts against one of the hooking portions from the inner surface side of the main body. A mounting device such as a thermostat.

With the above configuration, the thermostat is attached to the cooler by fitting the substantially L-shaped hooking portions provided at both ends of the strip and the holding claws into the slits provided in the cooler in advance. The substantially L-shaped hooking portion is elastically fixed from the inside by the one tongue-shaped pressing claw, and cannot be easily removed.

Embodiment Hereinafter, a thermostat mounting apparatus according to an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 is a cooler, and 2 is a thermostat housing, which has a cylindrical shape with a bottom and has a pi-metal thermostat built therein. A heat sensitive cap 3 is attached to seal one end of the housing 2. Four
Is a protrusion and is attached to the center of the other end of the housing 2.

As shown in FIGS. 2 and 3, reference numeral 5 denotes a body of a thermostat mounting device, which is formed of a strip material having a spring property such as stainless steel, and is provided with a thermostat mounting hole 6 for fitting with the protrusion 4, The main body 5 is attached to the housing 2 by fitting the protrusion 4 and the thermostat attachment hole 6 into each other. Reference numeral 7 denotes a presser pawl, which has a springy property and has a tongue shape in which a substantially U-shaped main body 5 is cut and raised, and is provided so as to contact the hook portion from the inner surface side of the main body 5.

In FIG. 2, 8 and 9 are substantially L-shaped hooking portions, which are provided at both ends of the main body 5. Numerals 10 and 11 are slits, which are formed in the cooler 1 and configured so that the substantially L-shaped hooking portions 8 and 9 provided at both ends of the mounting device body 5 can be fitted and locked.

The method of mounting the thermostat of this embodiment will be described below with reference to FIGS.

First, the substantially L-shaped hooking portion 8 provided in the thermostat mounting device main body 5 is inserted into the slit 10 provided in the cooler 1 in advance, and then the other slit L of the main body 5 is inserted into the other slit 11.
The hook portion 9 having a character shape is inserted. At this time, since the pressing claw 7 has a spring property, it does not enter the slit 11. Next, when the L-shaped hooking portion 9 is fixed in the slit 11,
Since the pressing claw 7 has a spring property, the pressing claw 7 can be fixed so that it does not enter the slit 11 and the substantially L-shaped hooking part 9 does not return.

As described above, according to the present embodiment, the pressing claw 7 is provided, and the pressing claw 7 is fitted into the slits 10 and 11 provided in the cooler 1 in advance, so that the thermostat can be attached to the cooler. It did not come off easily.

EFFECTS OF THE INVENTION As described above, according to the present invention, the substantially L-shaped hooking portions provided at both ends of the body of the substantially L-shaped springy material are fitted into the slits of the cooler, and one of the hooks is hooked. Since the fitting is elastically fixed by the tongue-shaped presser claw on the part side, it does not easily come off after the thermostat is attached to the cooler, providing an excellent thermostat attachment device. We were able to.
