Some specific embodiments of the utility model will be described in detail hereinafter, by way of illustration and not limitation, with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. Those skilled in the art will appreciate that the drawings are not necessarily drawn to scale.

Detailed Description
The utility model provides a refrigeration and freezing device, wherein FIG. 1 is a schematic structural diagram of the refrigeration and freezing device according to one embodiment of the utility model, and FIG. 2 is a partial structural diagram of the refrigeration and freezing device according to one embodiment of the utility model. Referring to fig. 1 and 2, the refrigerating and freezing apparatus 1 of the present invention includes a cabinet 10, an evaporator 20, a defrosting mechanism 30, and a water tray 40.
The case 10 defines a storage compartment 11 therein for storing articles. The refrigerator-freezer 1 of the embodiment shown in fig. 1 has two storage compartments 11 defined in the cabinet 10, but in a non-illustrated embodiment, only one storage compartment 11 or more than two storage compartments 11 may be defined in the cabinet 10 of the refrigerator-freezer 1.
The evaporator 20 is disposed in the cabinet 10 and is used for providing cold energy to the storage compartment 11. It is understood that the refrigerating and freezing device 1 may include a compressor 50, a condenser 80, a throttling member (not shown), and the like, in addition to the evaporator 20. The compressor 50, the condenser, the throttling element, and the evaporator 20 may be connected by refrigerant lines to form a refrigeration cycle circuit. When the compressor 50 is started, the evaporator 20 cools the air flowing therethrough, thereby forming a cooling air flow for supplying the storage compartment 11.
The defrosting mechanism 30 includes a water storage device 31 in which water is contained, a heating device 32 provided in the water storage device 31 to controllably heat the water in the water storage device 31, and a driving mechanism 33 for urging the water in the water storage device 31 toward the surface of the evaporator 20 to defrost the evaporator 20. Specifically, the water storage device 31 may be disposed outside the evaporator bin where the evaporator 20 is located, so as to avoid affecting structures such as an inner container and an air duct in the box 10 and occupying the space of the evaporator bin.
The drip pan 40 is disposed at the bottom of the evaporator 20 for receiving the condensed water generated by defrosting of the evaporator 20 and the water flowing to the surface of the evaporator 20 by the driving mechanism 33. The drain pan 40 communicates with the water storage device 31 to discharge the condensed water produced by defrosting of the evaporator 20 and the water flowing toward the surface of the evaporator 20 by the driving of the driving mechanism 33 into the water storage device 31. That is, the condensed water generated by defrosting of the evaporator 20 and the water for defrosting of the evaporator 20 supplied to the surface of the evaporator 20 are collected by the water receiving tray 40 and discharged to the water storage device 31, so that the water is recycled.
When the evaporator 20 needs defrosting, the water in the water storage device 31 is heated by the heating device 32, the heated water in the water storage device 31 is sent to the surface of the evaporator 20 by the driving mechanism 33, and the heated water transfers heat to the surface of the evaporator 20 to promote frost on the surface of the evaporator 20 to melt, so that the aim of effectively defrosting the evaporator 20 is fulfilled. Moreover, because the specific heat capacity of water is relatively high, the heat absorption speed and the heat release speed of water are relatively high, that is, the heat of water can be quickly transferred to the surface of the evaporator 20, and the defrosting speed of the evaporator 20 is relatively high. The heat transfer efficiency of the present application is higher and less energy consuming than the conventional way of radiating heat to the surface of the evaporator 20 by heating the surrounding air.
The traditional heating device built in the evaporator chamber is arranged externally, so that the heating device is arranged in the water storage device 31, the water storage device 31 is in a relatively open environment, the heating device 32 can be conveniently assembled and disassembled, the internal structure of the box body 10 cannot be influenced, and the safety is high. More importantly, the heat generated by the external heating device 32 is almost completely transferred to the water in the water storage device 31, so that hot air with high temperature is not generated, and temperature fluctuation in the storage chamber 11 caused by the hot air entering the storage chamber 11 can be avoided.
Specifically, the heating device 32 may be various heating devices that can be in direct contact with water or have good water resistance, for example, the heating device 32 may be a heating rod, a thick-film heating tube, a bare-wire heating tube, an infrared heating device, a quartz tube heating device, a carbon fiber heating device, or the like.
In some embodiments, the refrigerating and freezing apparatus 1 further includes an evaporation pan 60, and the evaporation pan 60 is communicated with the water storage device 31 to allow water in the water storage device 31 to flow to the evaporation pan 60 after the water level in the water storage device 31 reaches a preset water level.
That is, the water storage device 31 does not replace the evaporating dish of the conventional refrigerating and freezing device, and does not need to remove the evaporating dish of the conventional refrigerating and freezing device. When the water level in the water storage device 31 reaches the preset water level, the water in the water storage device 31 can flow to the evaporating dish 60, so that the water leakage phenomenon caused by excessive overflow of the water in the water storage device 31 and the influence on the safety of other components (such as a compressor) are avoided.
In some embodiments, evaporating dish 60 is at a lower vertical level than water storage device 31, so that water flows from high to low to evaporating dish 60.
Further, a water outlet equal to the preset water level is formed in a side wall of the water storage device 31, an overflow pipe 34 is connected to the water outlet, and a tail end of the overflow pipe 34 extends to the evaporation pan 60, so that water in the water storage device 31 automatically flows to the evaporation pan 60 through the overflow pipe 34 after the water level in the water storage device 31 reaches the preset water level. That is, the excessive water in the water storage device 31 can automatically flow to the evaporator 20 along the overflow pipe 34 without any driving structure, so that the structure of the refrigerating and freezing device 1 is simplified and the cost thereof is reduced.
In some embodiments, the water storage device 31 is disposed in the compressor compartment at the bottom of the tank 10, and the water storage device 31 is communicated with the water-receiving tray 40 through the drain pipe 70, so that the water-receiving tray 40 receives the collected water and flows to the water storage device 31 through the drain pipe 70.
Further, a compressor 50 is disposed in the compressor compartment, and the evaporating dish 60 is disposed adjacent to the compressor 50, for example, the evaporating dish 60 may be disposed above the compressor 50 or beside the compressor 50. Therefore, the water in evaporating dish 60 can be evaporated by the heat emitted from compressor 50 to avoid excessive overflow of water in evaporating dish 60.
In some embodiments, the refrigerated freezing apparatus 1 includes a condenser 80 in addition to the compressor 50. The compressor 50 is disposed in a compressor compartment at the bottom of the case 10. The condenser 80 is communicated with the exhaust port of the compressor 50, and a part of the pipe section of the condenser 80 passes through the water storage device 31, so that the condenser 80 exchanges heat with the water in the water storage device 31. On one hand, compared with the traditional condenser 80 which only exchanges heat with air, the condenser 80 has higher heat exchange efficiency with water, thereby improving the condensation efficiency of the condenser 80; on the other hand, the utility model also effectively utilizes the heat of the condenser 80 to heat the water in the water storage device 31, thereby not only recycling waste heat and avoiding energy waste, but also reducing the heating load of the heating device 32 in the water storage device 31, thereby reducing the energy consumption generated by the heating device 32. Also, when the evaporator 20 does not need to be defrosted, the condenser 80 can continuously heat the water in the water storage device 31 as long as the compressor 50 is operated, so that the water in the water storage device 31 maintains a high temperature, and when the evaporator 20 needs to be defrosted, the temperature of the water can be rapidly raised, thereby rapidly and effectively defrosting the evaporator 20.
Further, a portion of the tube section of the condenser 80 passes through the evaporating dish 60 such that the condenser 80 exchanges heat with the water in the evaporating dish 60, and the tube section of the condenser 80 passing through the evaporating dish 60 is downstream of the tube section of the condenser passing through the water storage device 31. That is to say, the condenser 80 firstly passes through the water storage device 31 and then passes through the evaporation pan 60, so that the heat generated by the condenser 80 preferentially heats the water in the water storage device 31, and then the excess heat heats the water in the evaporation pan 60, on one hand, the heat of the condenser 80 can be used for promoting the water in the evaporation pan 60 to evaporate, so as to avoid excessive overflow of the water in the evaporation pan 60, and on the other hand, the evaporation pan 60 can be used for further promoting the heat dissipation of the condenser 80, so as to improve the heat dissipation efficiency.
In some embodiments, the refrigerating and freezing device 1 further includes a dew-removing pipe 90, and the dew-removing pipe 90 may be connected in series in the flow path between the compressor 50 and the condenser 80 or in the flow path downstream of the condenser 80, and is used for heating and removing dew on a door body or a center sill of the refrigerating and freezing device 1. It should be noted that the series connection in the present invention means the series connection in the refrigerant flow path, that is, the compressor 50, the dew-removing pipe 90 and the condenser 80 are physically located at the upstream and downstream sides rather than in the electric circuit.
Further, a part of the dew-removing pipe 90 may also pass through the water storage device 31, so that the dew-removing pipe 90 exchanges heat with the water in the water storage device 31. That is, the present invention can also heat the water in the water storage device 31 by using the heat of the dew-removing pipe 90, further reducing the heating load of the heating device 32 in the water storage device 31, and thus reducing the energy consumption generated by the heating device 32. When the evaporator 20 needs defrosting, the temperature of the water can be quickly raised, thereby quickly and effectively defrosting the evaporator 20.
In some embodiments, the drive mechanism 33 may include an inlet conduit 331 and a pumping device 332. The water inlet pipe 331 is configured to introduce water in the water storage device 31 above the evaporator 20 to shower the evaporator 20. The water flows down toward the evaporator 20 from above, and the entire surface of the evaporator 20 can be more completely covered, thereby uniformly defrosting all over the evaporator 20.
A pumping device 332 is disposed in the water inlet pipe 331 and is configured to controllably pump water from the water storage device 31 to the water inlet pipe 331 so as to allow water to be poured over the evaporator 20 from above the evaporator 20. That is, the pumping device 332 serves to provide power for the flow of water from the water storage device 31 to the water inlet pipe 331. Specifically, the pumping device 332 may be a water pump.
Further, the pumping device 332 may be activated after the heating device 32 is turned on to ensure that the water flowing to the evaporator 20 is the water heated by the heating device 32 and effectively defrosting the evaporator 20.
In some embodiments, the driving mechanism 33 further includes a spraying device 333, the spraying device 333 has a water inlet communicated with the water inlet pipe 331 and at least one water spraying opening above the evaporator 20, and each water spraying opening is communicated with the water inlet through the spraying pipe to spray the water from the water inlet pipe 331 downwards to the evaporator 20 through the at least one water spraying opening, so that the sprayed water is uniformly received by all places of the evaporator 20, thereby facilitating uniform defrosting of the evaporator 20, shortening defrosting time and improving defrosting effect.
Further, the number of the water spray ports may be plural, and the plural water spray ports are uniformly distributed above the evaporator 20.
In some embodiments, the refrigerating and freezing device 1 further comprises a temperature sensor 91, and the temperature sensor 91 is disposed in the water storage device 31 and is used for detecting the temperature of the water in the water storage device 31. The driving mechanism 33 is configured to controllably urge water in the water storage device 31 toward the surface of the evaporator 20 according to the temperature of the water detected by the temperature sensor 91, and to controllably stop driving water in the water storage device 31 toward the surface of the evaporator 20 according to the temperature difference of the water in the water storage device 31 per unit time.
Specifically, when the temperature of the water detected by the temperature sensor 91 reaches the preset temperature threshold, the temperature of the water is sufficient to effectively melt the frost on the evaporator 20, and at this time, the driving mechanism 33 is turned on again to urge the water in the water storage device 31 to flow to the surface of the evaporator 20, so that the defrosting efficiency and the defrosting effect of the evaporator 20 can be improved, and the energy waste caused by the phenomenon that the driving mechanism 33 is turned on too early to generate ineffective frost is avoided.
Further, the predetermined temperature threshold may be 10 ℃ or higher. Preferably, the preset temperature threshold value can be 20-30 ℃, water in the range can meet the defrosting requirement, and adverse effects on the storage chamber caused by excessive temperature rise of air in the air duct can be avoided.
Applicants have recognized that during defrosting of evaporator 20, the temperature of the water returning to water storage means 31 is relatively low, and continues to reduce the temperature of the water in water storage means 31. Therefore, whether or not the frost on the evaporator 20 has been removed can be judged by the temperature difference of the water per unit time detected by the temperature sensor 91. When the frost on the evaporator 20 is completely removed, all the water in the water storage device 31 flowing back to the water storage box in a unit time is the water pumped out from the water storage device 31, therefore, the temperature difference of the water in the water storage device 31 in the unit time is reduced, and when the temperature difference reaches the preset temperature difference threshold value, the driving mechanism 33 can be controlled to stop driving the water in the water storage device 31 to the surface of the evaporator 20, so as to avoid unnecessary energy consumption of the driving mechanism 33.
