An embodiment of the present invention relates to a refrigerator.

Generally, a refrigerator includes a machine room provided at a lower portion of the main body. The machine room is generally installed at the lower part of the refrigerator for the center of gravity of the refrigerator, efficiency of assembling, and vibration reduction. The refrigerator's machine room is equipped with a refrigeration cycle device, which keeps the inside of the refrigerator in a frozen / refrigerated state by using the property of absorbing the external heat while changing the low-pressure liquid refrigerant into gaseous refrigerant, .

The refrigeration cycle apparatus of the refrigerator includes a compressor that changes a low-temperature low-pressure gaseous refrigerant into a high-temperature high-pressure gaseous refrigerant, and a high-temperature high-pressure gaseous refrigerant that is changed in the compressor to a high- A condenser, and an evaporator for absorbing external heat while changing the low-temperature and high-pressure liquid refrigerant changed in the condenser to a gaseous state.

On the other hand, when the refrigeration cycle of the refrigerator is driven, the evaporator absorbs heat from the outside, so that the surface of the evaporator is lower in temperature than the ambient temperature, so that the temperature can be congested.

In order to effectively remove such detergent water, Japanese Patent Laid-Open Publication No. 10-2014-0095787 discloses a machine room of a refrigerator provided with a dispenser tray.

In order to evaporate the dehydrated water collected in the dehydrator tray, it is advantageous to have a large surface area of the dehydrated water. However, in the case of a refrigerator having a plurality of compressors and a plurality of evaporators, the amount of the defrost water generated increases, but the space for disposing the defrost water tray is insufficient. Therefore, there is a problem that the amount of the distillation water inflow becomes larger than that of the distillation water collected in the remedial tray, resulting in overage of the dehydrated water.

It is an object of the present invention to provide a water purifier and a control method capable of drying a space in which an ice storage unit or an ice storage unit is accommodated.

According to an aspect of the present invention, a refrigerator includes a cabinet in which a first storage chamber and a second storage chamber are formed; First and second evaporators for cooling the first and second storage chambers; A machine room formed below the cabinet; A first compressor provided in the machine room to supply the refrigerant to the first evaporator; A second compressor provided in the machine room for supplying the refrigerant to the second evaporator; A first defrost hose for discharging the defrost water generated in the first evaporator to the machine room; A second defroster hose for discharging the defrost water generated in the second evaporator to the machine room; A first defroster tray provided on the bottom of the machine room for collecting defrost water discharged from the first defroster hose; And a second defrost water tray installed at an upper portion of the second compressor for defrosting the defrost water discharged from the second defroster hose, wherein the second defroster tray includes a storage portion for collecting the defrost water; And an outlet through which the dehydrated water collected in the storage unit is discharged to the first dehydrator tray.

The first storage chamber may be a freezing chamber, and the second storage chamber may be a refrigerating chamber.

The water collecting capacity of the first dehydrated water tray may be larger than the water collecting capacity of the second deicing water tray.

The refrigerator may further include a collecting plate provided in the storing part and storing a part of the defrost water flowing into the storing part on the upper part of the storing part.

Also, the storage unit may include a first storage unit and a second storage unit that are partitioned by the collection plate, the first storage unit is disposed above the second compressor, and the second storage unit is disposed outside the first storage unit As shown in Fig.

In addition, the outflow portion may include a discharge pipe having one end communicating with the storage portion and the other end extending toward the first defrost tray, and the defrost water collected in the storage portion may be discharged through the discharge pipe, You can move to the constant tray.

Further, the outlet may further include a drainage passage provided at one side of the discharge pipe to discharge the purified water collected in the storage section, and an end of the drainage passage is connected to the drainage passage, The first tray may be disposed above the first tray.

In addition, the end of the drain can be disposed above the drain pipe so that the dehydrated water discharged through the end of the drain can flow along the surface of the drain.

In addition, the end of the drain can be spaced apart from the bottom of the storage unit by a predetermined height.

The bottom surface of the first reservoir may be recessed to correspond to the shape of the upper surface of the second compressor.

In addition, the second dehydrated water tray may further include a fastening portion fastened to the upper portion of the second compressor.

In the case of the refrigerator of the present invention, the area of the defrost water tray is increased by providing a plurality of defrost water trays in the machine room of the refrigerator. Therefore, there is an advantage that the evaporation efficiency of the stripping water increases.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

FIG. 1 is a side view of a refrigerator according to an embodiment of the present invention, FIG. 2 is a rear view of the refrigerator of FIG. 1, and FIG. 3 is a view illustrating an interior of a refrigerator machine room according to an embodiment of the present invention.

1 to 3, a refrigerator 1 according to an embodiment of the present invention includes a cabinet 2 which forms an outer shape and a storage space formed inside the cabinet 2. As shown in FIG.

The storage space may include a first storage room formed at a lower portion of the cabinet 2 and a second storage room formed at an upper portion of the cabinet 2. [

In the refrigerator (1) of the present invention, the first storage room corresponds to the freezing room, and the second storage room corresponds to the refrigerating room. However, the spirit of the present invention is not limited thereto.

A machine room 5 is formed below the cabinet 2 and a refrigerant cycle component for driving the refrigerator 1 is accommodated in the machine room 5.

Specifically, a plurality of compressors (11, 12) and a condenser (13) for compressing the refrigerant may be installed in the machine room (5). A condensing fan 131 for improving the efficiency of the condenser 13 may be provided at one side of the condenser 13.

The plurality of compressors 11 and 12 include a first compressor 11 and a second compressor 12 that are seated on the bottom surface of the machine room 5. The first compressor (11) and the second compressor (12) can compress refrigerant at different pressures.

The refrigerant compressed in the first compressor (11) or the second compressor (12) is condensed in the condenser (13) and is depressurized in an expansion device (not shown). Next, the refrigerant moves to a plurality of evaporators (14, 15) and evaporates to cool the surrounding air.

The plurality of evaporators 14 and 15 may include a first evaporator 14 disposed at a lower portion of the cabinet 2 and a second evaporator 15 disposed at an upper portion of the cabinet 2.

The first evaporator (14) cools the first storage chamber, and the second evaporator (15) cools the second storage chamber.

Since the first evaporator 14 is for cooling the freezer compartment and the second evaporator 15 is for cooling the refrigerating compartment, the first evaporator 14 is configured to have a larger capacity than the second evaporator 15 .

The refrigerator (1) further includes a plurality of defrost hoses (21, 22) for discharging defrost water generated during driving.

The first evaporator (14) and the second evaporator (15) may be cooled due to air cooling, and a defrosted water is generated while thawing. At this time, the plurality of defroster hoses (21, 22) can discharge the purified water generated in the first evaporator (14) and the second evaporator (15) to the machine room (5).

The plurality of defroster hoses 21 and 22 are provided with a first defrost hose 21 for discharging the defrost water generated in the first evaporator 14 to the machine room 5, And a first defrost hose (22) for discharging the generated defrost water to the machine room (5).

The refrigerator (1) comprises a first defrost water tray (100) for collecting defrost water discharged from the first defroster hose (21), and a second defrost hose for collecting the defrost water discharged from the second defroster hose And may include a dehydrator tray 200.

The defrost water collected in the first and second defrost water trays 100 and 200 may be removed through evaporation.

On the other hand, the evaporated water can be promoted by the heat generated in the machine room 5. In addition, the evaporation efficiency of the defrost water collected in the first and second defrost water trays 100 and 200 may increase as the evaporation area increases.

The refrigerator 1 may further include a blowing fan (not shown) provided at one side of the first removing tray 100 or the second removing tray 200. The air blowing fan blows air with the defrost water collected in the first defrost water tray 100 or the second defrost water tray 200 to further increase the evaporation efficiency.

The first dehydrator tray 100 may be seated on the bottom surface of the machine room 5. The first dehydrator tray 100 may be disposed between the first compressor 11 and the second compressor 12 as shown.

The second tidal water tray 200 may be seated on the upper end of the second compressor 12. Accordingly, the distillation water collected in the second tidal water tray 200 can be promoted to be evaporated by the heat generated in the second compressor 12.

The second dehydrating tray 200 may be disposed at the upper end of the first compressor 11 instead of the second compressor 12. [ That is, the second tidal water tray 200 is disposed at a higher position than the first tidal water tray 100.

When the plurality of compressors 11 and 12 are provided as in the refrigerator 1 of the present invention, since the space of the machine room 5 is narrow, the second separator tray 200 is disposed at the upper end of the second compressor 12 It is effective to secure the space of the machine room 5.

The first defrost hose 21 is connected to the first defrosting tray 100 so that the defrost water generated by the first evaporator 14 can be collected in the first defrosting tray 100.

The second defrost hose (22) may be connected to the second defrost water tray (200). Therefore, the second dehydrator tray 200 can collect deionized water generated by the second evaporator 15.

Since the first evaporator 14 is for cooling the freezer compartment, the capacity of the second evaporator 15 is larger than that of the second evaporator 15, and accordingly, the amount of defrost water generated is large. Therefore, the first dehydrated water tray 100 may have a greater storage capacity than the second dehydrated water tray 200.

The refrigerator 1 is provided with a discharge pipe 23 provided in the second defrost water tray 200 for moving the defrost water collected in the second defroster water tray 200 to the first defroster tray 100, As shown in FIG.

One end of the discharge pipe 23 may be connected to the second defrost water tray 200 and the other end may extend toward the first defroster tray 100.

The second degasser tray 200 is difficult to accommodate a large amount of defrost water because the space at the upper end of the second compressor 12 is narrow. Accordingly, the defrost water flowing into the second defrost water tray 200 is moved to the first defroster tray 100 so that the defrost water collected in the second defrost water tray 200 is overflowed .

In addition, in the process of moving the defrost water collected in the second defrost water tray 200 to the first defroster tray 100, the evaporation efficiency due to the flow of defrost water may be increased.

Hereinafter, the structure of the first dehydrated water tray 100 and the second dehydrated water tray 200 will be described in detail.

FIG. 4 is a perspective view of the first disposable water tray of FIG. 3; FIG.

4, the first dehydrator tray 100 includes a storage unit 111, a first fixing unit 102, a second fixing unit 103, and a third fixing unit 104, 105 .

And serves to store the defrost water discharged from the first defroster hose (21) or the discharge pipe (23). The storage unit 111 may be formed in a wide tray shape to store the dehydrated water and spread the dehydrated water widely to evaporate the dehydrated water.

The first fixing part 102 may protrude upward from the bottom surface of the storage part 111.

The first fixing part 102 is inserted into the discharge pipe 23 to fix the discharge pipe 23. Therefore, the diameter of the first fixing part 102 may be smaller than the diameter of the inner circumferential surface of the discharge pipe 23.

The condenser (13) may be coupled to the second fixing part (103). Accordingly, the condenser 13 can be fixed to the first degreasing tray 100.

The condensing fan 131 may be coupled to the third fixing parts 104 and 105. Accordingly, the condensing fan 131 can be fixed to the first degreasing tray 100.

The first tamponage tray 100 is fixed to the bottom surface of the machine room 5 so that a separate fixing member (not shown) may be provided on the bottom surface of the first tamponage tray 100.

Hereinafter, the structure of the second tenter tray 200 will be described in detail.

FIG. 5 is a perspective view of a second dispenser tray according to an embodiment of the present invention, and FIG. 6 is a bottom view of the dispenser tray of FIG.

Referring to FIGS. 5 and 6, the second defrost water tray 200 includes a storage unit 210 for collecting defrost water discharged from the second defroster hose 22.

The capacity of the storage unit 210 provided in the second tidal water tray 200 may be smaller than the capacity of the storage unit 111 provided in the first tidal water tray 100.

The second tidal water tray 200 may further include a discharge port 220 connected to the discharge pipe 23. The defrost water collected in the storage unit 210 may flow to the discharge pipe 23 through the discharge port 220.

The second tidal water tray 200 may further include a drainage passage 230.

The drain passage 230 may be formed at a position spaced apart from the bottom surface of the storage unit 210 by a predetermined height. Accordingly, when the dehydrated water having a height equal to or higher than the height of the drainage path 230 is collected in the storage unit 210, the defrosted water can flow to the first defecation tray 100 through the drainage path 230.

The end of the drainage path 230 may be disposed vertically above the storage unit 111 of the first dehydrating tray 100. Accordingly, the defrost water discharged through the end of the drain can 230 can freely fall into the first defrost tray 100.

The end of the drain passage 230 may be disposed vertically above the discharge pipe 23. Accordingly, the defrost water dropping from the end of the drain canal 230 flows along the surface of the discharge pipe 23 and can be introduced into the first defrost tray 100.

Accordingly, it is possible to prevent the defrosting water dropping from the drainpipe 230 from dropping off directly to the defrost water collected in the first defrosting tray 100 to prevent splashing of water.

On the other hand, the end of the drain can 230 may be disposed adjacent to the first defrost hose 21. Accordingly, the defrost water dropping from the end of the drain can 230 flows along the surface of the first defroster hose 21 and can be introduced into the first defroster tray 100.

The draining passage 230 may be formed at a position adjacent to the outlet 220. Accordingly, when the drain pipe 23 is clogged with foreign matter or the like, and the drain water can not be moved through the drain port 220, the drain water can be moved by the drain water pipe 230.

The drain passage 230 may be formed by extending a part of the storage unit 210. Also, as shown in the drawing, the drainage passage 230 may have a half pipe shape and a shape that becomes narrower toward the end side. However, the shape of the drain passage 230 is not limited to this shape.

The defrost water collected in the storage unit 210 flows to the first defroster tray 100 through the discharge pipe 23 or the drain pipe 230 so that the discharge pipe 23 and the drain pipe 230 Collectively, it can be called a spill.

The bottom part 212 of the storage part 210 may be formed in a shape that is depressed depending on the shape of the upper end of the second compressor 12. [ This is because the space of the machine room 5 is narrow, so that the upper space of the second compressor 12 is used effectively.

The bottom portion 212 of the storage portion 210 may be recessed so that the bottom portion of the storage portion 210 may have a protrusion 213 projecting upward. The defrost water discharged from the second defrost hose 22 may be discharged toward the protrusion 213.

Since the second compressor 12 is provided at the lower end of the protrusion 213, the evaporation efficiency of the defrost water collected in the storage unit 210 can be increased by the heat generated by the second compressor 12 have.

The second defrosting tray 200 may further include a collecting plate 215 installed on the protrusion 213 to collect a predetermined amount of defrosted water discharged from the second defroster hose 22. [

The collector plate 215 may have a plate shape protruding upward from the surface of the protrusion 213. However, the shape of the water collecting plate 215 is not limited thereto.

The storage unit 210 may be partitioned into a first storage unit 216 and a second storage unit 217 by the collection plate 215.

The first storage unit 216 may be defined at the upper end of the protrusion 213 and the second storage unit 217 may surround the first storage unit 216.

Since the first storage unit 216 is disposed above the second compressor 12, the defrost water collected in the first storage unit 216 is discharged from the second storage unit 217, Evaporation rate is fast.

The second dehydrated water tray 200 may further include a coupling part 214 to be coupled to the second compressor 12. The second tidal water tray 200 may be fixed to the second compressor 12 by the coupling part 214.

Meanwhile, the coupling part 214 may have a shape in which a part of the protrusion 213 is cut. Accordingly, a hole 214a may be formed at one side of the coupling part 214. [

The second defrost hose 22 may be spaced apart from the hole 214a to prevent the defrost water discharged through the second defroster hose 22 from flowing into the hole 214a.

The second degreasing tray 200 may further include a water overflow prevention part 218 provided on the protrusion 213.

The water overflow prevention part 218 prevents the defrost water collected in the first storage part 216 from flowing to the second compressor 12 through the hole 214a. Accordingly, the water overflow prevention portion 217 may protrude upward from the protruding portion 213. The upper end of the water overflow prevention portion 218 may be formed higher than the upper end of the water collecting plate 215.

Meanwhile, as shown in the figure, the water overflow prevention portion 217 may be formed in an open top and bottom for ease of manufacturing, but is not limited thereto.

The second tidal water tray 200 may further include a plurality of coupling portions 241 and 243 provided outside the storage portion 210.

The plurality of coupling portions 241 and 243 may be connected to the cabinet 2. Accordingly, the second tidal water tray 200 can be fixed to the cabinet 2. [

The plurality of coupling portions 241 and 243 may be formed with coupling holes into which coupling members such as bolts can be inserted.

The second tidal water tray 200 may further include wire guiding portions 245 and 247 provided outside the storage portion 210.
