Abstract

PROBLEM TO BE SOLVED: To provide an evaporating dish which speeds up evaporation concerning the evaporating dish in a machine room. SOLUTION: Defrosting water is stored into a first water storage part 8 formed on the arched top part of a compressor and an overflow of water from the first water storage part 8 is stored into a second water storage part 9 which is separated from the first water storage part 8 by a section wall 7 and formed on the outer circumference of the first water storage part 8. The second water storage part 9 is arranged at a position shifted to the outer circumference from the top part of the compressor. Therefore, the evaporation from the first water storage part 8 which makes it easy to receive heat from the compressor is so arranged to occur earlier than that from the second water storage part 9 which makes it hard to receive heat from the compressor. This minimizes the evaporation from the second water storage part 9 thereby eliminating matters which adheres onto the bottom of the evaporating dish and causes malodor.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an evaporating dish disposed above a compressor in a machine room of a refrigerator.

[0002]

2. Description of the Related Art Refrigerators in recent years have a large interior space for improving the inner volume efficiency and have been actively developed for rationalization.

[0003] Some conventional refrigerators are disclosed in Japanese Patent Laid-Open No. 9-11 / 1990.
There is one disclosed in Japanese Patent No. 3114.

Hereinafter, the conventional refrigerator will be described with reference to the drawings. FIG. 5 is a rear view of a main part of a machine room of a conventional refrigerator, and FIG. 6 is a sectional perspective view of a main part of an evaporating dish of the refrigerator.

In the figure, a compressor 52,
A condenser 53 is housed, and the compressor 5
3. A closed circuit is formed through the capillary tube 54 to the cooler disposed in the refrigerator, the pipe 52 forms the closed circuit to the compressor 52, and the refrigerant is circulated to constitute a refrigeration cycle.

Further, convection is generated in the machine room 51 by the fan 56 and the electric motor 57, and the outside air is sucked in from the front of the refrigerator as indicated by the arrow, thereby improving the condensation capacity of the condenser 53 and cooling the compressor 52. It was something like that. Reference numeral 58 denotes a partition plate to which the electric motor 57 is attached, which also serves as a partition for generating high and low pressure when generating wind by the electric motor 57. A foam material 59 is wound around the outer periphery of the partition plate 58 to seal a gap with the bottom plate 60.

[0007] The evaporating dish 61 is disposed above the compressor 52 so as to evaporate defrost water stored in the evaporating dish 61 by the heat of the compressor 52. The outer shape of the evaporating dish 61 is reduced, and the space of the machine room 51 is made compact. For this reason, the bottom of the evaporating dish 61 has a convex portion 61a formed along the outer shape of the upper portion of the compressor 52 so as to increase the water storage efficiency and easily receive the heat of the compressor 52. At the lower end of the evaporating dish 61, a drain port 61b for discharging the water in the evaporating dish 61 when moving the refrigerator is formed.
Is provided.

[0008]

In the above-mentioned conventional configuration,
Since the evaporating dish 61 is disposed above the compressor 52 and is configured to evaporate defrost water in the evaporating dish 61 by the heat of the compressor 52, the shape of the bottom of the evaporating dish 61 is A convex portion 61a is formed along the outer shape of the upper part of 52,
The defrost water accumulates at the bottom of the valley 61c adjacent to the projection 61a of the evaporating dish 61. The temperature in the evaporating dish 61 is highest in the convex portion 61a located directly above the compressor 52, and the valley portion 61 where the defrost water easily accumulates receives the heat of the compressor 52 most strongly.
c had the disadvantage that the evaporation rate was slow and a bad smell was generated at the portion where dirt and the like adhered.

An object of the present invention is to solve the conventional problems, and an object of the present invention is to provide an evaporating dish with an increased evaporation rate.

[0010]

SUMMARY OF THE INVENTION In order to achieve this object, the present invention provides an evaporating dish disposed above a compressor, the evaporating dish being formed along a mountain-top of the compressor. A partition wall is provided between the convex portion of the bottom surface and a valley portion which is located on the outer periphery of the convex portion and is located on the outer periphery from the mountain-like top portion of the compressor. A water storage section, water from the cooler is stored in a first water storage section at a central portion defined by the partition wall, and water overflowing from the first water storage section is formed on an outer periphery of the partition wall. The water is stored in the second water storage section. Therefore, the water storage depth of the first water storage part, which is easy to receive the heat of the compressor, is increased, and the water storage depth of the second water storage part, which is difficult to evaporate, is made shallower than the first water storage part. This facilitates evaporation from the second water storage section, and eliminates a problem that an attached substance adheres to the bottom of the evaporating dish and generates an odor.

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a first water storage section and a second water storage section, wherein a partition wall is formed in an evaporating dish disposed above a compressor and having a bottom formed along the top of the compressor. Form a part,
Pour defrost water from the cooler into the first reservoir of the evaporating dish,
Water overflowing from the first water storage section is stored in the second water storage section. The partition wall has a convex portion along the mountain-top portion of the compressor, and a portion which is most susceptible to heat of the compressor and a portion which is off the outer periphery from the mountain-top portion of the compressor. Between the valleys. Therefore, the first in the center of the evaporating dish
Even if the water depth of the water storage part is deep, the water is evaporated by the heat of the compressor. Further, the water storage depth of the second water storage section is shallower than the water storage depth of the first water storage section, so that even in the second water storage section where it is difficult to receive the heat of the compressor, evaporation is quick. The present invention can be implemented by configuring the evaporating dish to perform the above functions.

Further, by providing a drain plug in the second water storage section, the water stored in the second water storage section can be drained when the refrigerator is moved. The drainage structure can also have a good sealing performance by being implemented with a special seal structure. Therefore, a specific configuration in the embodiment of the present invention will be described in detail below as an example.
