[ detailed description of the invention ]
Please refer to the drawings, and particularly to fig. 1. The refrigerator 1 comprises a compartment with a plurality of heat insulation. In the present embodiment, the refrigeration appliance 1 includes a freezing chamber 2, a refrigerating chamber 3, and an ice temperature chamber 4.
The temperature of the freezer compartment 2 may be set well below zero degrees celsius, for example-18 degrees celsius, and the contents of the freezer compartment 2 may freeze, for example water may freeze.
The freezing chamber 2 may have an evaporator chamber 12 at the rear thereof, and a first evaporator 21 to cool the freezing chamber 2 is provided in the evaporator chamber 12. In the present embodiment, the first evaporator 21 is a fin evaporator. The cold air cooled by the first evaporator 21 can be forcibly discharged into the storage area 14 located in front of the evaporator chamber 12 by the first fan 13. The warmer air in the storage area 14 can be returned to the evaporator chamber 12 via the air outlet 23 located at the bottom of the evaporator chamber 12. With this, when the first evaporator 21 is operated, air can be forcibly circulated within the freezing chamber 2.
During operation of the refrigeration device 1, the first evaporator 21 can frost. To this end, the refrigeration appliance 1 comprises a first defroster 22 arranged in association with the first evaporator 21.
When the first defroster 22 is turned on, the temperature of the first evaporator 21 and the air in the vicinity of the first evaporator 21 is increased, and frost attached to the first evaporator 21 is dissolved. The first defroster 22 may generate electricity based on a resistance, such as a potential heater.
The first defroster 22 may be operatively connected to the control system of the refrigeration device 1 and activated on the basis of a detection signal, but the first defroster 22 may also be activated or deactivated depending on a time parameter.
The refrigerator 1 has a first drain pipe 60, and the defrosted water in the freezing chamber 2 is discharged out of the freezing chamber 2 through the first drain pipe 60.
The storage temperature of the refrigerating chamber 3 is greater than zero degrees centigrade, for example, 2 to 8 degrees centigrade. The storage temperature of the ice-cold room 4 is near zero, but the water stored in both rooms does not freeze. Therefore, both the refrigerating compartment 3 and the ice-warming compartment 4 may be referred to as a non-freezing compartment.
The refrigeration appliance 1 comprises a second evaporator 31 and a third evaporator 41 to cool the refrigerating compartment 3 and the ice-warming compartment 4, respectively.
In one embodiment, the second evaporator 31 and/or the third evaporator 41 is attached to a side of the corresponding inner wall 30, 40 facing the thermal insulation layer 50 to cool the inner wall 30, 40 into a cooling wall (cold wall) to which air in the refrigerating compartment 3 and the freezing compartment 4 is heat-exchanged. In another embodiment, the second evaporator 31 and/or the third evaporator 41 are located in the refrigerating compartment 3 and the ice greenhouse 4, respectively, but close (e.g. against, or at a small distance from) the inner walls 30, 40, and the air in the refrigerating compartment 3 and the ice greenhouse 4 is in direct heat exchange with the evaporators 31, 41. In a further embodiment it is also possible that the cold compartment 3 and/or the cold compartment 4 are provided with evaporators in the same way as the freezer compartment 2.
The second fan 33 may be provided in the refrigerating compartment 3. The second fan 33 can be used to agitate the air inside the refrigerating compartment 3 to homogenize the temperature distribution and/or to create a forced circulation inside the refrigerating compartment 3 (in particular when ducts are also provided inside the refrigerating compartment 3).
When the refrigerant is cooled by the second evaporator 31, frost occurs in the refrigerating compartment 3, and the frost may be distributed on the second evaporator 31 or the cooling wall directly cooled by the second evaporator 31. When the second evaporator 31 stops operating, the frosted second evaporator 31 or the cooling wall is gradually melted by heat exchange with the air in the refrigerating compartment 3. Therefore, the refrigerating compartment 3 may not be provided with a defroster.
An air duct plate 42 may be provided in the ice greenhouse 3 near the third evaporator 41 or the inner wall 40 cooled by the third evaporator 41 to form an air duct therebetween, and the cooled air may be forcibly circulated in the ice greenhouse 3 by the air duct and a fan (not shown) to reduce the temperature gradient of the ice greenhouse 3.
Similarly, when the refrigerant is cooled by the third evaporator 41, frost may occur in the ice greenhouse 4, and the frost may be distributed on the third evaporator 41 or on a cooling wall directly contact-cooled by the third evaporator 41. When the third evaporator 41 stops operating, the frosted third evaporator 41 or the cold wall is gradually melted by heat exchange with the air in the ice greenhouse 4. The fans located within the ice-cold greenhouse 4 may also be operated quickly for a period of time to promote defrosting of the ice-cold greenhouse 4. A defroster may also be provided in the ice-making chamber 4. It is apparent that the operating frequency of the defroster in the ice-temperature compartment 4 is significantly lower than that in the freezer compartment 2.
The refrigerator 1 has a second drain pipe 70 for draining the defrosted water of the refrigerating chamber 3 and the freezing chamber 4 to the outside of the respective chambers. It should be understood that in an alternative embodiment, the refrigerating chamber 3 and the ice-warming chamber 4 may have their insides drained out of the chamber by different drain pipes.
The refrigeration appliance 1 comprises a water receiver 5 for receiving defrost water. As shown in fig. 2 to 4, in this embodiment, the receptacle 5 is a box-like receptacle including a bottom wall 51 and a peripheral wall 10, and is located in the machine room 52.
The water receiver 5 is internally provided with a separation element 9 which is separated into a first water storage cavity 6 and a second water storage cavity 7 which are not communicated. The first water storage chamber 6 and the second water storage chamber 7 are not communicated at least at a predetermined height, and thus, the first and second water storage chambers 6, 7 have a predetermined water storage depth, respectively.
The condenser 8 is positioned above the water receiver 5. The partition element 9 may at the same time have the function of supporting the condenser 8.
In this embodiment, the partition element 9 is connected at both ends to the peripheral wall 10 of the receptacle 5 so that the first water storage chamber 6 and the second water storage chamber 7 are side by side. Obviously, it is also possible to arrange the first water storage chamber 6 and the second water storage chamber 7 in the manner of an inner chamber and an outer chamber.
The defrosted water of the freezing chamber 2 is discharged into the first water storage chamber 6 through the first drain pipe 60. The defrosted water of the refrigerating chamber 3 and the freezing chamber 4 is discharged into the second water storage chamber 7 through the second drain pipe 70. It should be understood that it is also possible that the defrosted water of the refrigerating chamber 3 and the freezing chamber 4 is separately drained into the second water storage chamber 7 through a drain pipe, differently.
The refrigerator 1 is provided with a heat source for accelerating the evaporation rate of water in the second water storage chamber 7. In the embodiment shown in fig. 2 and 3, a part of the condensation duct 80 of the condenser 8 is extended into the second water storage chamber 7 to form a heat source.
The condensation duct 80 extends into the second water storage chamber 7 to a certain depth so that the condensation duct 80 is submerged in the defrosting water as much as possible.
Under the condition that only non-freezing chamber defrosting water exists, the defrosting water exchanges heat with the condenser 8 only in the second water storage cavity 7, and compared with the common water receiving box 5 which is not divided, the defrosting water storage box has the following advantages:
since the refrigerating chamber 3 and the ice-warming chamber 4 are likely to be defrosted after each stop of cooling, the defrosting frequency of the refrigerating chamber 3 and the ice-warming chamber 4 is significantly higher than that of the freezing chamber 2, and the defrosting water amount of the freezing chamber 2 is significantly higher than that of the refrigerating chamber 3 and/or the ice-warming chamber 4 during each defrosting, therefore, the defrosting water of the non-freezing chamber can be kept in the second accommodating chamber 7 and evaporated to absorb heat to take away more condenser heat, so that the condenser temperature is more effectively reduced to improve the cooling efficiency; partial pipelines of the condenser extend into the second water storage cavity 7, so that the evaporation of defrosting water is accelerated, and the evaporation water quantity of the water receiving box 5 is ensured.
Although the first water storage cavity 6 and the second water storage cavity 7 are not communicated, an overflow port 11 may be provided between the first water storage cavity 6 and the second water storage cavity 7. When the defrosting water exceeds the storage height of the first water storage chamber 6 and the second water storage chamber 7, the defrosting water on one side can overflow to the other side.
As shown in fig. 4, the partition member 9 includes a baffle 15 having a height lower than the peripheral edge of the receptacle 5, and an overflow port 11 is formed above the baffle 15 from between the first water storage chamber 6 and the second water storage chamber 7. In this embodiment, the height of the baffle 15 corresponds to the highest water storage height/highest water level of the first and second water storage chambers 6, 7, below which there is no communication between the first and second water storage chambers 6, 7.
Obviously, a plurality of overflow ports may be provided between the first water storage chamber 6 and the second water storage chamber 7, and the shape and position of the overflow ports should not be limited to the illustrated embodiment, and may be one or more holes in the partition member 9, for example.
The volume of the first water storage chamber 6 is smaller than that of the second water storage chamber 7. This is more favorable to arranging of condenser pipe 80 in second water storage chamber 7, and is favorable to preventing the water in second water storage chamber 7 to first water storage chamber 6 overflow, and when the freezer 2 defrosts, because the freezer volume of defrosting water is many, water can stride overflow mouth 11 and flow into second water storage chamber 7, is favorable to increasing the evaporation capacity of water.
In the above embodiment, the refrigerator has two non-freezing chambers, and the defrosted water of both the two non-freezing chambers flows into the second water storage chamber. It should be understood that the present invention should not be limited thereto, and for example, it is also possible that the defrosted water of only one non-freezing chamber among the plurality of non-freezing chambers is discharged to the second water storage chamber, and of course, it is also possible that the refrigerator has only one non-freezing chamber.
