Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention provides a drainage evaporating tray installed above a compressor in a refrigerator machine room, and a first evaporating tray installed in the evaporating tray. A second evaporation tank is provided, the first evaporation tank performs forced evaporation using the radiant heat of the compressor, and the second evaporation tank performs forced evaporation using the radiant heat of the compressor.
The evaporator is a waste water evaporating dish with high evaporation efficiency that performs forced evaporation and natural evaporation using an evaporator equipped with a pipe on the high pressure side of the refrigeration cycle.

[Prior art]

The structure of the drain evaporator for this type of refrigerator is as shown in Figures 1 and 2. To explain it with reference to Figure 1, two rails 3 are fixed with screws to the atitor 1 on the back of the refrigerator, and a An evaporator 4 is disposed above the compressor 2, and a high-pressure pipe for a refrigeration cycle is installed inside the evaporator tray 4.

A drain pipe 6 leads the defrosting water generated inside the refrigerator to the above-mentioned evaporation tray 4 outside the refrigerator. Further, to explain the evaporation effect with reference to FIG. 2, which shows a cross section of a conventional example, in order to reduce the installation space and secure the internal volume of the evaporating dish 4, the top part 4C of the compressor 2 is made concave, and the surrounding area is made concave. 4b and 4C are made flat and expanded to both sides, and a high pressure pipe 5 of a refrigeration cycle is laid in these parts. In addition, in the evaporating dish 4, the 4C portion that receives the radiant heat of the compressor 2 is the highest temperature, and the high pressure pipe 5
However, since the peripheral parts 4b and 4c are less affected by the radiant heat of the compressor 2, the 4C part does not reach a high temperature. However, the defrosting water discharged from the inside of the refrigerator accumulates from the peripheral parts 4b and 4c other than the evaporating dish 4a, and when a certain amount of water reaches a certain level, the part 4C is submerged. Furthermore, due to variations in installation, it is difficult to install the evaporating dish 2 horizontally, so the defrosting water must be 4B or 4C.
This has the disadvantage that the radiant heat of the compressor 2 cannot be used effectively.

[Purpose of the invention]

The present invention relates to a structure in which defrosting water during defrosting of a refrigerator is efficiently evaporated by natural evaporation and forced evaporation in a drainage evaporation tray installed above the compressor in the machine room of the refrigerator. .

[Summary of the invention]

That is, the present invention first forcibly evaporates the defrosting water discharged after defrosting in the center of the evaporating dish, which is most affected by the radiant heat of the compressor. The frost water floods around the evaporating dish and is forced to evaporate naturally in the armpit by heat from high-pressure pipes.

[Embodiments of the invention]

The embodiment will be described below with reference to the drawings. Reference numeral 11 denotes an atitor on the back of the refrigerator, to which a metal fitting 13 and an evaporating plate 4 attached with screws are fixed so as to be positioned at the top of the compressor 2. The evaporating dish 1
4 has a first evaporation tank 14a and a peripheral part 14b thereof in a portion facing the compressor 2, and a second evaporation tank 4C. The first evaporation tank and the second evaporation tank are separated by a barrier 14d.

Further, a member 17 with good heat absorption (for example, a metal plate painted in a dark color) is closely attached to the outer surface of the first evaporation tank 14a on the compressor 2 side, and the second evaporation tank 14b is closed.

A high pressure pipe 15 is installed at 14C. 16 is a drain pipe that guides defrosting water to the evaporating dish 14.

In this configuration, the defrosting water discharged outside the refrigerator is first led to the first evaporation tank 14a of the evaporator 14, and most of the defrosting water (is stored here, and the remaining water is stored in the second evaporation tank 14a). The first evaporating tank is forcibly evaporated by the radiant heat of the compressor 2. The member 17 also promotes absorption of the radiant heat received by the first evaporating tank 14a at this time. When the system is not operating, it functions to transfer the stored heat to the evaporation plate.

The defrosting water flowing down into the second evaporation tank is forced to evaporate by the high-pressure pipe 15 when the refrigerator is in operation, and naturally evaporates when the refrigerator is not in operation.

〔Effect of the invention〕

In the present invention, a barrier is provided in the evaporating dish to partition the evaporating tank into a first and a second evaporating tank, a heat absorbing member is closely attached to the outer surface of the first evaporating tank, and a high pressure pipe is laid inside the second evaporating tank. By doing so, the defrosting water is reliably kept in the central part of the evaporating dish where the evaporating capacity is highest, and the defrosting water is allowed to overflow into the first and second evaporating plates, thereby improving the evaporating capacity.
