Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a refrigerator comprising a vibration-absorbing water evaporator provided above a compressor.

Conventional technology In recent years, in order to improve the volumetric efficiency (storage volume/external volume) of household refrigerators, defrost water evaporation trays have been downsized and defrost water evaporation trays have been compressed to effectively utilize ineffective space. Refrigerators that are mounted on top of machines are increasingly being installed. However, depending on how the evaporation tray is installed, it may not be possible to maintain sufficient evaporation capacity permanently, and in the worst case, a problem may arise in which water overflows from the defrost water evaporation tray.

The above conventional example will be explained below with reference to FIGS. 4, 6, and 6. Reference numeral 1 denotes the main body of the refrigerator, which is constructed by filling a heat insulating material 4 between an outer box 2 and an inner box 3. A cooler 6 for cooling the inside of the refrigerator 6 is provided on the inner back surface of the refrigerator main body 1, and a cooler cover 7 is provided on the front of the cooler 6.
A blower 8 is installed above the cooler 6 to supply cold air to the inside 6 of the refrigerator. Further, below the cooler 6, a defrost water receiver 9 made of plastic material is arranged to receive the defrost water from the cooler 6, and a drainage pipe 10 integrally molded with the defrost water receiver 9 receives the defrost water. The structure is such that water is drained outside the warehouse. Next, the compressor 11
The compressor 11 is placed on the compressor mounting plate 13 via the
A defrosting water evaporation tray 14 is placed on top of the compressor 11 in close contact with the compressor 11 for heat exchange. A protrusion 14b is provided above the back plate 14a of the defrosting water evaporating dish 14, and by inserting this into the socket pin 15 fitted in the outer box 2, the defrosting water evaporating dish 14 prevents it from falling off.

In the above configuration, the frost formed on the cooler 6 during the cooling operation is drained into the defrost water evaporation tray 14 via the defrost water receiver 9 and the drain pipe 10 during defrosting.

Since the defrost water evaporation tray 14 is in close contact with the compressor 11 for heat exchange, the defrost water drained into the defrost water evaporation tray 14 is
It is heated by the compressor 11 and automatically evaporated into the atmosphere.

Problems to be Solved by the Invention However, in the above configuration, the vibration isolating rubber 12 deteriorates over time due to the weight or heat of the compressor 11.
If sagging occurs (when the height is reduced), the defrost water evaporation tray 14 and the compressor 11 will definitely separate, creating a gap between them. The water is not heated sufficiently, and its evaporation capacity is significantly reduced.As a result, although there is no problem when shipping the product, after a few years,
This could lead to complaints from customers that water overflowed from the defrost water evaporation tray and leaked onto the floor.

In view of the above-mentioned six problems of the conventional example, the present invention has a defrost water evaporation tray mounting structure that can maintain normal evaporation capacity even if the anti-vibration rubber wears down (reduction in height) due to aging. It provides a refrigerator.

Means for Solving the Problems In order to solve the above problems, the refrigerator of the present invention is provided with a hook for hanging a defrosting water evaporating dish on the refrigerator body, and a hook for hanging the defrosting water evaporating dish on the back plate of the defrosting water evaporating dish. A long hole is provided in the vertical direction to stop the defrosting water evaporating dish, and a long play area is provided above the 7. Schiff when the defrosting water evaporating dish is normally installed.

Effect of the present invention With the above configuration, even if the vibration-proof rubber supporting the compressor becomes sagging (reduction in height dimension) due to aging and the compressor position is lowered, the defrost water evaporation tray can be hooked up. Since there is a long play allowance above, it is possible to descend while staying in close contact with the compressor, and therefore, normal evaporation capacity can be maintained permanently.

Example Below, an example of the present invention is shown in Figs. 1, 2, and 3.
This will be explained with reference to the diagram. Regarding 1 to 13 in the figure,
Since it is completely the same as the conventional example, the same figure number will be added and the explanation will be omitted. The difference from the conventional example is the shape of the defrost water evaporation dish 16, with elongated holes 18 provided in the back plate 17, and the refrigerator body 1
The point is that a hook 19 is provided on the back side of the holder. Also, Chodai 1
8 consists of an elongated part 18a and a round hole part 18b having an inner diameter larger than the outer diameter of the shifter 19. To install the defrosting water evaporating dish 16, first pass the tip of the shifter 19 through the round hole 18b, Next, the defrosting water evaporation tray 16 is pushed down until it hits the compressor 11.

The dimensions of the elongated portion 18a are set so that a free play 18c remains in the normal state in which the defrosting water evaporation tray 16 is mounted as described above.

To explain the operation in the above configuration, as the compressor 110 changes over time due to weight and heat, the vibration isolating rubber 12 sag (reduces in height) and the compressor 11 tends to sink downward. If this continues, the defrost water evaporating dish 1
A gap is created between the hook 6 and the compressor 11, making it impossible to conduct heat and significantly deteriorating the evaporation capacity. As the compressor 11 sinks, the defrosting water evaporating tray 16 descends, and the defrosting water evaporating tray 16 and the compressor 11 are always in close contact with each other. In addition, the gap between the seven hooks 19 and the long portion 18a is made slightly loose so that the defrosting water evaporating tray 16 can easily slide downward, and furthermore, the defrosting water does not accumulate in the defrosting water evaporating tray 16. Good, its weight naturally defrosts water evaporating dish 1
6 is lowered to increase the degree of contact with the compressor 11.

Effects of the Invention As described above, the present invention provides a hook for hanging a defrosting water evaporation tray on the refrigerator main body, and providing a long vertical length on the back plate of the defrosting water evaporation tray for hanging on the hook. When the frost water evaporation plate is normally installed, there is a slot of play in the long hole at the top of the 7th hole, so the vibration isolating rubber of the compressor will deteriorate over time (the height will shrink) and the compressor will move downward. Even if the defrost water evaporation tray sinks, the defrost water evaporation tray follows this and the compressor and the defrost water evaporation tray are always in close contact with each other, thereby permanently maintaining normal evaporation capacity.
