Description

[Detailed description of the invention] [Industrial application field] This invention is a cooling device that connects a compressor, condenser, evaporator, etc. with refrigerant piping. This invention relates to a mounting device for a heater.

[Conventional technology]

Figures 4, 5, and 6 show this type of conventional cooling system. In the figures, 1 is a compressor, 2
is a condenser, 3 is a condenser blower, and these are mounted on a unit base 5 fixed on the top panel 4 of the refrigerator.
placed above. In addition, a through hole 6 is provided in the top panel 4 on one side of the unit base 5.
is surrounded by an insulating box 14, and inside this insulating box 14, the evaporator 7, the evaporator blower 8, and the drain pan 9 are installed.
are arranged and fixed to the connecting member 10. Note that this connecting member 10 is connected to the unit base 5. Also, the compressor 1 is installed at the bottom of the drain pan 9.
The heating coil 11 through which the discharged gas flows is connected to the presser plate 1.
2 and is fastened with a screw 13.

[Problem that the invention attempts to solve]

In the cooling device configured as described above, when fixing the heating coil 11 to the drain pan 9, there are many places where screws are fastened, as shown in FIG. It was difficult to assemble, as it required coating. In addition, if the sealing material 18 was poorly applied, drain may drip into the refrigerator through the penetration portion. Also, small particles (spores, paper scraps, etc.) sucked in by the evaporator blower 8 from inside the refrigerator.
Sometimes this mixes with the drain and sticks to the drain pan 9, obstructing the flow of the drain.In that case, the drain pan 9 must be removed and cleaned, but there are many screw-fastened points, so there are problems such as the hassle of servicing. It was hot.

On the other hand, as shown in FIGS. 7 and 8, there is another method of fixing the heating coil 11 to the drain pan 9 using a saddle 15, but this requires many spot welding points and is difficult to work with. When cleaning the drain pan 9,
There were some problems, such as not being able to remove it.

This invention aims to eliminate the above-mentioned drawbacks and provide a cooling device that satisfies proper functions and has good workability.

[Means for solving problems]

The heater mounting device according to this invention places the heater on a fixing plate, and holds this fixing plate together with a drain pan by a U-shaped elastic fixing member, thereby fixing the heater. The elasticity of the member is used to attach it closely to the drain pan.

[Effect]

In this design, the heater is placed on a fixed plate, and the drain pan is fixed by pressing the fixing plate with the fixing member, which is a U-shaped elastic body, so that the heater is tightly pressed against the drain pan and the fixed plate. and fixed.

〔Example〕

An embodiment of this invention will be described below with reference to Figs. 1 to 3. First, as shown in Fig. 3, a heating coil 1
2, the fixing plate 16 is placed on a U-shaped elastic fixing member 17 having bent locking pieces 17a on both side edges and having arcuate projections 17b on both sides of the bottom surface, and the projections 17b are pressed against the fixing plate 16, so that the bent locking pieces 17a are bent at an acute angle (angle θ in FIG. 2) of the fixing member 17.
The heating coils 9 may be replaced with heaters.

[Effect of idea]

This idea is structured as above, so
The heater can be easily fixed to the drain pan using the U-shaped fixing member, and since the heater is pressed against the drain pan with the entire surface of the fixing plate, the drain pan can be easily removed, making it easy to clean the drain pan and replace the heater. It has great practical effects, such as easy replacement.
