Detailed Description
The present invention will be described in detail below with reference to embodiments shown in the drawings. However, these embodiments do not limit the present invention, and structural or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
Referring to fig. 1 to 2, in a first embodiment of a refrigerator according to the present invention, the refrigerator 100 includes: the refrigerator comprises a refrigerating chamber 10, a temperature-changing chamber 20, a freezing chamber 30 and a refrigerating system 80, wherein the temperature-changing chamber 20 is arranged between the refrigerating chamber 10 and the freezing chamber 30, and the refrigerating system 80 provides cold refrigeration for the refrigerating chamber 10, the temperature-changing chamber 20 and the freezing chamber 30. The refrigeration system 80 includes a compressor 81, a condenser 82, a capillary tube 83, an evaporator 84, and a return air tube 85 connected in series in a circuit.

The refrigerating chamber air outlet 11 is communicated with the upper part of the evaporator cavity 40 through a refrigerating chamber air supply duct 50, the variable temperature chamber air outlet 21 is communicated with the upper part of the evaporator cavity 40 through a variable temperature chamber air supply duct 60, the freezing chamber air outlet is communicated with the evaporator cavity 40 through a freezing chamber air supply duct (not marked in the figure), the refrigerating chamber air return inlet 12, the variable temperature chamber air return inlet 22 and the freezing chamber air return inlet are communicated with each other through an air return duct 70, and the air return duct 70 is communicated with the lower part of the evaporator cavity 40. The air passing through the evaporator 84 is cooled to a lower temperature, the cooled air is driven by the fan 41 to be respectively sent to the refrigerating chamber 10, the temperature-changing chamber 20 and the freezing chamber 30 through the refrigerating chamber air supply duct 50, the temperature-changing chamber air supply duct 60 and the freezing chamber air supply duct, then is respectively collected into the return air duct 70 from the refrigerating chamber return air inlet 12, the temperature-changing chamber return air inlet 22 and the freezing chamber return air inlet, and then returns to the evaporator cavity 40 to be cooled again, so that the refrigerating chamber 10, the temperature-changing chamber 20 and the freezing chamber 30 are refrigerated.
In the invention, a refrigerating chamber air door 13 is arranged between a refrigerating chamber air outlet 11 and a fan 41, a temperature-variable chamber air door 23 is arranged between a temperature-variable chamber air outlet 21 and the fan 41, and the refrigerating chamber air door 13 and the temperature-variable chamber air door 23 are respectively used for controlling whether to supply air to a refrigerating chamber air supply duct 50 and a temperature-variable chamber air supply duct 60. The air cooled by the evaporator 84 is blown to the refrigerating room damper 13 and the temperature-varying room damper 23 by the driving of the fan 41, and whether or not to blow air to the refrigerating room 10 and the temperature-varying room 20 is controlled by the refrigerating room damper 13 and the temperature-varying room damper 23.
In the use process of the refrigerator 100, the outside air inevitably enters the cold air circulation of the refrigerator 100, compared with the air inside the refrigerator 100, the temperature of the air entering from the outside is high, the humidity is high, after the air is cooled by the evaporator 84, because the condensation effect of the evaporator 84 is limited, the water vapor in the air in the refrigeration circulation of the refrigerator cannot be completely condensed, the air can be condensed out, when the temperature is lower, the condensed water can be directly condensed into frost, in the refrigeration circulation process, along with the flowing of cold air, most of the water vapor in the air in the refrigerator can be condensed on the surface of the evaporator 84, because the surface area of the evaporator 84 is smaller, the water vapor can not be completely condensed on the surface of the evaporator, at the moment, the air is cooled, the water vapor in the air can form frost, along with the flowing of the air, the frost particles in the air can be attached to various surfaces contacted with the evaporator, when passing through the refrigerating compartment damper 13 and the variable compartment damper 23, condensation is condensed on the surfaces of the refrigerating compartment damper 13 and the variable compartment damper 23, and the condensation is more and more accumulated with time. When the evaporator 84 is defrosted again, the temperature around the evaporator 84 rises, at the moment, frost on the surface of the evaporator 84 and around the refrigerating chamber air door 13 and the temperature-changing chamber air door 23 is melted into water drops, and then the water drops fall and flow away, but a small part of water drops are still attached to the surfaces of the above structures, and when the evaporator 84 is defrosted and refrigerated again, the water drops attached to the refrigerating chamber air door 13 and the temperature-changing chamber air door 23 are frozen again, so that the refrigerating chamber air door 13 and the temperature-changing chamber air door 23 are frozen. The present invention is directed to solving the above-mentioned problems, i.e., reducing the formation of frost on the damper, when the condensation of the evaporator 84 is insufficient, increasing the secondary condensation to reduce the moisture in the air in the refrigeration cycle, and after the above two condensations, the frost condensed on the damper is very little and will not freeze on the damper.
The refrigeration system 80 includes a compressor 81, a condenser 82, a capillary tube 83, an evaporator 84, and a return air tube 85 connected in series in a circuit. The refrigerant is discharged from the compressor 81, enters the condenser 82 for cooling, exchanges heat with the air return pipe 85 through the capillary pipe 83, enters the evaporator 84 for evaporation and heat absorption, is sucked into the compressor 81 again through the air return pipe 85 for compression for the next refrigeration cycle, and circulates repeatedly in the refrigeration system 80 of the refrigerator in such a way to finish the refrigeration of the refrigeration compartment of the refrigerator. In this embodiment, at least a portion of the pipeline 851 of the return air pipe 85 in the refrigeration system 80 is disposed in the return air duct 70, because the temperature of the refrigerant in the return air pipe 85 is low, the temperature of the pipe wall of the return air pipe 851 is also low, and the temperature of the return air in the return air duct 70 is high, and the air with high temperature meets the return air pipe 851 with low temperature, so that water is easily condensed on the return air pipe 851, and the water condensed in the return air duct 70 can flow into a water collecting tank (not shown in the figure) below the evaporator 84 along the return air duct 70, thereby increasing the condensation frequency of the moisture in the air and reducing the humidity in the air.
Preferably, the capillary tube 83 is disposed inside the muffler 85, the capillary tube 83 is allowed to pass through the muffler 85, and heat exchange is performed in the axial direction and the radial direction by the refrigerant flowing through the capillary tube 83 and the muffler 85, thereby improving heat exchange efficiency.
Referring to fig. 3-4, which are schematic views of a second embodiment of the present invention, compared with the first embodiment, the difference is: in the second embodiment, at least a part of the pipeline 851 of the return air pipe 85 is arranged at the refrigerating room return air inlet 12, the return air at the refrigerating room return air inlet 12 has higher temperature, and the return air with higher temperature meets the part of the pipeline 851 of the return air pipe 85 with lower temperature, so that water is easily condensed on the return air pipe 851. A water receiving box 86 is arranged below the air return pipe 851 positioned at the air return opening 12 of the refrigerating chamber and used for collecting water condensed and dropped by the air return pipe 851, thereby increasing the condensation frequency of moisture in the air and reducing the humidity in the air.
Preferably, a drain port 861 is further disposed on the water receiving box 86, the drain port 861 is externally connected to a drain pipe (not shown in the figure) of the refrigerator, and water in the water receiving box 86 is drained out of the refrigerator 100 along the drain pipe after being filled, so as to prevent water in the water receiving box 86 from overflowing.
Referring to fig. 5-6, which are schematic views of a third embodiment of the present invention, compared with the first embodiment, the difference is: the third embodiment places at least a portion of the tubes 841 of the evaporator 84 in the return air duct 70, because the temperature of the refrigerant in the evaporator 84 is low, the tube wall temperature of the evaporator tubes 841 is also low, while the return air in the return air duct 70 is hot, and the hot return air meets the evaporator tubes 841 which are hot, so that water is easily condensed on the evaporator tubes 841, and the water condensed in the return air duct 70 can flow along the return air duct 70 to a water collecting tank (not shown) below the evaporator 84, thereby increasing the condensation frequency of the moisture in the air and reducing the humidity in the air.
Referring to fig. 7-8, which are schematic views of a fourth embodiment of the present invention, compared with the second embodiment, the difference is: in the fourth embodiment, at least part of the pipeline 841 of the evaporator 84 is arranged at the refrigerating chamber return air inlet 12, the return air at the refrigerating chamber return air inlet 12 has higher temperature, the air with higher temperature meets the evaporator pipeline 841 with lower temperature, water is easy to condense and flow out on the evaporator pipeline 841, and a water receiving box 86 is arranged below the evaporator pipeline 841 at the refrigerating chamber return air inlet 12 and is used for collecting the water condensed and dropped by the evaporator pipeline 841, thereby increasing the condensation frequency of the water in the air and reducing the humidity in the air.
Preferably, a drain port 861 is further disposed on the water receiving box 86, the drain port 861 is externally connected to a drain pipe (not shown in the figure) of the refrigerator, and water in the water receiving box 86 is drained out of the refrigerator 100 along the drain pipe after being filled, so as to prevent water in the water receiving box 86 from overflowing.
Referring to fig. 9-10, a fifth embodiment of the present invention is schematically illustrated, and the fifth embodiment is a modification of the third embodiment, and this embodiment also places at least part of the pipe 841 of the evaporator 84 in the return air duct 70 for cooling and dehumidifying, but compared with the third embodiment, the difference is that: the fifth embodiment employs two capillaries 831 and 832, wherein the first capillary 831 is located in the same position as the capillary 83 in the third embodiment in the return air pipe 85, and the second capillary 832 is located between the evaporator 84 and the partial pipe 841 of the evaporator. The refrigerant is discharged from the compressor 81, enters the condenser 82 for cooling, then exchanges heat with the air return pipe 85 through the first capillary tube 831, enters the evaporator pipeline 841 in the air return duct 70, enters the second capillary tube 832, enters the evaporator 84 for evaporation and heat absorption, and is sucked into the compressor 81 again through the air return pipe 85 to be compressed and retracted for the next refrigeration cycle. Wherein the second capillary 832 is disposed between the evaporator 84 and the evaporator tube 841, so that the present embodiment dehumidifies first on the evaporator tube 841 and then cools on the evaporator 84.
