Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention provides a machine room at the bottom of the refrigerator, covers the opening of the machine room with a machine room cover, and supplies defrosting water from the cooler to the top of the compressor. This relates to a refrigerator that is equipped with an evaporating dish.

[Background of the invention]

A conventional refrigerator of this kind has a machine room 3 in which a compressor 2 is installed in the lower part of the refrigerator body 1, as shown in Utility Model Application Publication No. 58-19037-100 (Figures 9 and 10). , a machine room cover 4 is provided to cover the opening of the machine room, and
This cover 4 is provided with an evaporating dish inlet/outlet 6 and an evaporating dish support stand 7 connected to the inlet/outlet 6G, and the evaporating dish 5 inserted through the evaporating dish inlet/outlet 6 is placed on this support stand 7.
Is it shown that the evaporating dish 5 is placed above the compressor 2 and spaced apart from the compressor 2 at a position where the defrosting water of the cooler drawn from inside the refrigerator falls? With the range of content shown in this publication, there were various problems in efficiently evaporating the defrosting water drawn from the refrigerator into the cooler. In other words, in order to increase the evaporation efficiency of the evaporating dish, it is necessary to conduct heat from the compressor to the evaporating dish to raise the temperature of the water in the evaporating dish as much as possible, and to improve the convection of the air around the evaporating dish so that the heat can be transferred to the evaporating dish after evaporation. It is necessary to quickly release the moist air outside the machine room and draw in fresh air instead, but this problem of accelerating evaporation has not been mentioned much. During operation, the vibration noise of the compressor is transmitted through the refrigerator body to the machine compartment cover.
The above-mentioned publication does not mention at all whether the evaporating plate placed on the support base G of the cover may generate resonance noise in some cases.

[Purpose of the invention]

The present invention has been made in view of the above points, and specifically discloses how to promote the evaporation of defrosting water accumulated in the evaporating dish, and also discloses a method for promoting the evaporation of defrosting water accumulated in the evaporating dish. The purpose is to provide a concrete structure that can be attached to the machine room cover without causing any problems.

[Summary of the invention]

In other words, in a refrigerator in which an evaporation tray is installed above a compressor installed in a machine room at the bottom of the refrigerator to receive defrost water from the cooler, the bottom of the evaporation tray has a shape that approximately matches the shape of the top of the compressor. The evaporating tray 18 is installed to cover the bottom of the evaporating tray or the top of the compressor through flexible rubber, and an air vent chimney is provided inside the evaporating tray 18 located at the top of the compressor. The object of the present invention is achieved by providing a recess in a portion of the bottom of the evaporating dish to form a passage for guiding the air.

[Embodiments of the invention]

The details of the present invention will be explained below with reference to an embodiment shown in FIGS. 1 to 8. Reference numeral 11 indicates the refrigerator body, and 12 indicates the interior of the refrigerator body. Reference numeral 13 indicates a blockage of the front opening of the refrigerator interior 12, and reference numeral 14 indicates a machine room formed in the lower part of the refrigerator main body 11. This machine room 14 includes a bottom plate 11a forming the outer shell of the refrigerator main body 11, a base 15,
This refers to a room surrounded by a machine room cover 16, etc., which will be described later. In the present invention, the bottom plate 11 forming the ceiling of the machine room 14
a has good heat dissipation from the compression plate 17 (described later), and the evaporation plate 1
8. In order to improve the convection of surrounding air, as shown in FIG. 2, it is formed with an inclined surface that becomes higher toward the opening of the machine room. 17 is a compressor installed in the machine room 14, and 18 is an evaporating dish, the details of which will be described later, which is installed above the compressor 17. Reference numeral 19 denotes a defrosting water conduit outlet for introducing defrosting water from a cooler (not shown) into the evaporator @ 18 from the inside 12 side.

Next, to explain the shape, mounting structure, etc. of the evaporating dish 18 and machine room cover 16, the evaporating dish 18 is shown in FIGS. 2 and 4. In addition to being placed on a flexible rubber 20 with good elasticity, it is also attached via a vibration isolating rubber 21, which will be described later, which is attached to the machine room cover 16.

In other words, the evaporating tray 18 is configured so that the vibration noise of the compressor 17 and the mechanical compartment cover 16 and the compressor, which is elastically supported by the refrigerator, does not propagate to the evaporating tray 18. Also, the bottom 18a of this evaporating dish 18 is connected to the previous compressor 17.
The shape of the upper part 17a of the evaporating dish 17a is approximately the same as that of the evaporating dish bottom 18 through the flexible rubber 20 pasted on the compressor.
In addition to being attached to cover the upper part 17a of the compressor, an air vent chimney 22 for promoting heat dissipation from the compressor 17 is provided approximately in the center of the bottom part 18a of the evaporating dish.

23 sends the air warmed by the compressor 17 to the air vent chimney 2
A part of the evaporating dish bottom 18a formed to cover the compressor upper part 17a is recessed to form a passage.
A passage for heat radiation is formed between the compressor upper part 17a and the upper part 17a of the compressor.

Reference numeral 18b denotes a partition wall provided inside the evaporating dish 18, as shown in FIG. By arranging the water conduit outlet 19 to face a small chamber located at the top of the compressor 17, the defrosting water of the cooler can be supplied to the compressor 1 up to a certain amount.
A small chamber located at the upper part of the defrosting water tank 7 is provided with a pond so that defrosting water exceeding a certain amount overflows over the partition wall 18b and into the adjacent small chamber.

24 is a handle that covers the entire front part of the evaporating dish 18, and an air passage is formed between the handle 24 and the front wall 18C of the evaporating dish.
Furthermore, there is a slit 25 in the handle portion at the upper end of the path.
is provided. Of course, this slit 25 is the slit 2 which is an air suction port provided in the machine room cover 16, which will be described later.
This is provided to efficiently discharge the air sucked in from the evaporator 6 and warmed by the compressor 17 to the outside of the machine room, thereby promoting evaporation in the evaporating dish 18. Reference numeral 24a denotes locking portions provided at both ends of the handle 24 of the evaporating dish 17, and by locking the head portion 21a of the vibration isolating rubber 21 fitted to the machine room cover 16 mentioned above to the locking portions 24H. , the evaporating dish 18 so that the surface of the evaporating dish handle 24 is approximately the same surface as the machine room cover 16.
A machine room cover 161 is installed.

When pulling out the evaporating dish 18 from the machine room cover 16, as shown in FIGS. 2 and 5, place your hand in the notch @ 24b provided in the center of the handle 24 and lift the handle 24 upward. 24. Remove the locking portions 24a provided at both ends from the head 21a of the vibration isolating rubber 21 fitted to the machine room cover 16, and open the evaporating plate entrance/exit 27 provided on the machine room cover 16.
It would be better to draw out more.

Next, the machine room cover 16 of the present invention will be explained. As shown in the figure, the machine room cover 16 has a slit 26 serving as an air inlet to the machine room 14, and also has a slit 26 which is an air inlet to the machine room 14.
7. Further, a vibration isolating rubber 21 is fitted onto the side wall 16a surrounding the evaporating dish 18, as shown in FIGS. 6 and 7.

The air sucked in through the slit 26 of the machine room cover 16 ascends through the air passage between the evaporating dish handle 24 and the front wall 18c as indicated by the arrow in FIG. The air passing through the slit 25 and sucked in through the gap 28 between the base 15 and the bottom plate 11a of the refrigerator body passes through the recess 23 provided in the evaporating dish 18 and the air vent chimney 22, and both pass through the top surface of the evaporating dish 18 and the machine. It is discharged to the outside of the machine room 14 from a gap 29 between the ceiling surfaces of the room.

At this time, in the present invention, since the slit 26 serving as the air suction port is provided below the position of the evaporation plate 18 installed on the compressor 17, all the air sucked through the slit 26 is warmed by the compressor 17 and becomes an upward air flow. Since the defrost water is discharged outside the machine room 14, the convection of the air around the evaporating dish 18 becomes good, and the evaporation of the defrosting water in the evaporating dish 18 is promoted.

In FIG. 8, a cut-and-raised piece 30 is provided on a part of the rib forming the left and right slits 26 of the machine room cover 16, so that a power cord 31 can be hung thereon as shown in the figure.

Evaporation of defrosting water in a refrigerator having such a configuration is performed as follows. That is, the defrosting water of the cooler is first passed from the refrigerator interior 12 through the defrosting water conduit outlet 19 to the partition wall 18b of the evaporating tray 18.
The water is introduced into a small chamber at the top of the compressor. In this part, the bottom part 18a of the evaporating dish is in direct contact with the flexible rubber 20 with good thermal conductivity, and since it almost matches the shape of the upper part of the compressor, the water temperature is the highest in this part. The air passage is formed by the air vent chimney 22, the recess 23 forming the air passage, the totte 24, and the front wall 18c, and the slit 25 is provided on the top surface of the totte, so the base 15 and the bottom plate are connected as shown in FIG. The air sucked in from the gap 28 of 11a and the slit 26 of the machine room cover is sent to the compressor 17.
The water heats the evaporating pan 18 while being warmed by the heat dissipated, and becomes an upward air current that heats the evaporating pan 18 and is discharged outside the machine room 14 through the gap 29. As a result, the temperature of the water inside the evaporating pan 18 rises, and the water around the evaporating pan 18 (particularly the evaporation Since the convection of air on the upper surface of the related tray becomes active, the evaporation of the defrosting water in the evaporating tray 18 is promoted. Of course, at this time, the bottom plate 11a that constitutes the machine room 14
Needless to say, the fact that the ceiling surface of the building was sloped was very effective.

Furthermore, in the present invention, a slit 26 serving as an air suction port made in the machine room cover 16 or an evaporation plate 1 installed on the compressor 17 are used.
Since the position is lower than position 8, all the air sucked in from the slit 26 is heated by the compressor 17 and becomes an upward airflow that heats the evaporating dish 18 and increases the convection flow rate of the air around the evaporating dish 18, so that the air is evaporated. The efficiency is further increased.

In addition, when the defrost water in the cooler exceeds the capacity of the small chamber at the top of the compressor of evaporator 11118, it overflows to the next small chamber, so of course evaporation also occurs from this part, although the amount of evaporation is smaller than the small chamber at the top of the compressor. will be carried out.

Next, in the present invention, the evaporating dish 18 is attached to the flexible comb 2 on the compression plate.
0 and elastically supported by vibration-proof rubber 21 of the machine room cover,
tN, the vibration noise of the compressor 17 does not propagate and generate resonance noise from the evaporating dish 18 during operation of the refrigerator. Furthermore, a cut-and-raised piece 30 is provided using a part of the rib forming the slit 26 of the machine room cover, and the cut-and-raised piece 30
Since there is only one cord so that one power cord 31 can be hung thereon, the power cord 31 can be easily disposed of when the refrigerator is installed.

〔Effect of the invention〕

As explained above, the present invention provides a refrigerator in which an evaporating tray for receiving defrosting water from a cooler is installed above a compressor provided in a machine room at the bottom of the refrigerator. The evaporating dish is shaped approximately to match the shape of the evaporating dish, and is attached via flexible rubber so that the bottom part of the evaporating dish covers the top of the compressor, and an air vent chimney is provided at the bottom of the evaporating dish located above the compressor. Since the chimney G has a recess at the bottom of the evaporating pan to form a passageway, the heat from the compressor is conducted directly to the evaporating pan through the flexible rubber, and the heat from the compressor is also directly conducted to the evaporating pan through the flexible rubber. The warmed air becomes an updraft that passes through the recess at the bottom of the evaporating dish and the air vent chimney, which serve as air passages, and is discharged outside the machine room. This increases the convective flow of air around the evaporating dish, which reduces the amount of air removed in the evaporating dish. Evaporation of frost water is promoted.
