Description

Technical Field

[0001] The present application relates to the technical field of household appliances, for example, to a refrigeration device. Background Art

[0002] During the operation of the refrigeration equipment, when the air in the refrigeration equipment passes through the surface of the evaporator, the moisture in the air will condense on the surface of the evaporator. Due to the low temperature of the evaporator, a frost layer will form after a period of time. The frost layer will affect the cooling effect of the refrigeration equipment, and the frost layer on the surface of the evaporator needs to be removed in time. There is usually a water tray under the evaporator. If the frost on the surface of the evaporator falls to the water tray and blocks the drainage hole of the water tray, it will cause a large negative pressure in the refrigeration equipment, making it difficult to open the equipment door of the refrigeration equipment.

[0003] In the related art, a refrigeration device includes a heating element and a heat conducting sheet. The heating element is used to defrost an evaporator, and the heat conducting sheet connects the heating element and a water receiving tray to conduct the heat of the heating element to the water receiving tray.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] When the evaporator defrosts, the heating element is turned off and the refrigeration equipment restarts cooling. If the frost or defrost water in the water tray is not completely drained, the low temperature of the evaporator will cause the drain outlet of the water tray to be blocked.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0037] During the operation of the refrigeration equipment, when the air in the refrigeration equipment passes through the surface of the evaporator, the moisture in the air will condense on the surface of the evaporator. Due to the low temperature of the evaporator, a frost layer will form after a period of time. The frost layer will affect the cooling effect of the refrigeration equipment, and the frost layer on the surface of the evaporator needs to be removed in time. There is usually a water tray under the evaporator. If the frost on the surface of the evaporator falls to the water tray and blocks the drainage hole of the water tray, it will cause a large negative pressure in the refrigeration equipment, making it difficult to open the equipment door of the refrigeration equipment.

[0038] In the related art, the refrigeration device includes a heating element and a heat conducting sheet. The heating element is used to defrost the evaporator, and the heat conducting sheet connects the heating element and the water receiving tray to transfer the heat of the heating element to the water receiving tray. However, when the evaporator is defrosted, the heating element is turned off, and the refrigeration device restarts refrigeration. If the frost or defrosted water in the water receiving tray is not completely drained, the low temperature of the evaporator will cause the drain outlet of the water receiving tray to be blocked.

[0039] The embodiments of the present disclosure provide a refrigeration device, which can heat the drainage hole of a water receiving tray when the refrigeration device is defrosting or refrigerating, thereby reducing the risk of clogging of the drainage hole of the water receiving tray.

[0040] Combination Figures 1 to 4 As shown, the refrigeration device provided by the embodiment of the present disclosure includes an evaporator 100 , a compressor 200 , a heating element 300 , a water receiving tray 400 , a first heat conducting plate 500 , and a second heat conducting plate 600 .

[0041] The heating element 300 is used to defrost the evaporator 100. The heating element 300 generates heat to melt and remove the frost layer on the surface of the evaporator, thereby defrosting the evaporator 100.

[0042] The water receiving tray 400 is disposed below the evaporator 100 and is provided with a first drainage hole and a second drainage hole. The water receiving tray 400 is disposed below the evaporator 100 and is used to receive frost ice falling off the surface of the evaporator and defrosting water dripping from the surface of the evaporator.

[0043] Two ends of the first heat conducting sheet 500 are respectively connected to the heating element 300 and the hole wall of the first drain hole. The first heat conducting sheet 500 is used to conduct the heat of the heating element 300 to the first drain hole when the heating element 300 defrosts the evaporator 100.

[0044] Two ends of the second heat conducting sheet 600 are respectively connected to the compressor 200 and the second drain hole. The second heat conducting sheet 600 is used to conduct the heat of the compressor to the second drain hole when the compressor 200 is working.

[0045] In the refrigeration device provided by the embodiment of the present disclosure, when the refrigeration device defrosts the evaporator 100, the heating element 300 generates heat to melt the frost layer on the surface of the evaporator 100, and the first heat conducting sheet 500 can conduct the heat of the heating element 300 to the first drain hole to melt the frost in the first drain hole, so that the first drain hole remains unobstructed. When the refrigeration device is refrigerating, the compressor 200 is working, and the heating element 300 stops generating heat, and the second heat conducting sheet 600 can conduct the heat of the compressor 200 to the second drain hole to melt the frost in the second drain hole, so that the second drain hole remains unobstructed. Therefore, when the refrigeration device is defrosting and refrigerating, at least one of the first drain hole and the second drain hole remains unobstructed, which is conducive to reducing the risk of blockage of the drain outlet of the water receiving tray 400.

[0046] In some embodiments, the material of the water receiving tray 400 includes metal, which has good thermal conductivity and can melt the frost in the water leakage box more quickly. For example, the material of the water receiving tray 400 is stainless steel, aluminum or copper.

[0047] In some embodiments, the material of the first heat conductive sheet 500 includes metal, which has good thermal conductivity and can improve the heat conduction rate between the heating element 300 and the hole wall of the first drain hole. For example, the material of the first heat conductive sheet 500 is stainless steel, aluminum or copper.

[0048] In some embodiments, the material of the second heat conductive sheet 600 includes metal, which has good thermal conductivity and can improve the heat conduction speed between the heating element 300 and the hole wall of the first drain hole. For example, the material of the second heat conductive sheet 600 is stainless steel, aluminum or copper.

[0049] In some embodiments, in combination Figure 4 As shown, the bottom surface 402 of the water receiving tray 400 is provided with a drain port 401. The water receiving tray 400 also includes a partition plate, which is vertically arranged at the drain port 401 to separate the drain port 401 into a first drain port and a second drain port. In this way, it is convenient to set the first drain port and the second drain port on the bottom surface 402 of the water receiving tray 400. It is sufficient to add a partition plate on the basis of the existing water receiving tray without opening two holes, which facilitates the processing and manufacturing of the water receiving tray 400.

[0050] In some embodiments, the material of the partition includes metal, which has good thermal conductivity and can improve the heat conduction rate between the first drain port and the second drain port. For example, the material of the partition is stainless steel, aluminum or copper.

[0051] Optionally, the material of the partition is the same as that of the water receiving tray 400, which facilitates processing and manufacturing.

[0052] Optionally, the partition is connected by welding to the hole wall of the drain port 401. The welding connection not only enables the partition to be firmly arranged at the drain port 401, but also ensures the heat conduction effect between the two.

[0053] In some embodiments, the partition is provided with a connecting hole, and the connecting hole is used to connect the first drain hole and the second drain hole. By providing the connecting hole on the partition, the air in the first drain hole and the air in the second drain hole can flow, which is conducive to promoting heat exchange between the first drain hole and the second drain hole, thereby facilitating melting of frost and ice in the two drain holes, and further reducing the probability of clogging of the first drain hole and the second drain hole.

[0054] Optionally, the partition is provided with a plurality of communicating holes.

[0055] In some embodiments, in combination Figure 2 As shown, the water receiving tray 400 includes a plurality of partitions, which are spaced apart along the height direction of the drain outlet 401. The partitions extend along the vertical direction.

[0056] The partitions are spaced apart along the height direction of the drain port 401, that is, the first drain hole and the second drain hole can be connected through the gap between the partitions. In this way, the air in the first drain hole and the air in the second drain hole can flow, which is conducive to promoting heat exchange between the first drain hole and the second drain hole, thereby facilitating melting of frost and ice in the two drain holes, and further reducing the probability of clogging of the first drain hole and the second drain hole.

[0057] In some embodiments, in combination Figure 1 and Figure 2 As shown, the water receiving tray 400 further includes a drain pipe 403. The drain pipe 403 is disposed at the drain port 401 and extends toward the lower side of the water receiving tray 400. In the case where the water receiving tray 400 includes the drain pipe 403, the partition is disposed at the drain pipe 403. By providing the drain pipe, it is convenient to guide the defrost water in the water receiving tray 400 to the evaporating dish. At the same time, providing the drain pipe can reduce the distance between the drain port 401 and the evaporating dish, thereby reducing the splashing of the defrost water.

[0058] It is understandable that, when the water receiving tray 400 includes the drain pipe 403 , the partition is vertically disposed on the drain pipe 403 to separate the inner space of the drain pipe 403 into a first drain outlet and a second drain outlet.

[0059] Optionally, the drain pipe 403 is arranged in the drain port 401 in an interference fit manner. In this fitting manner, the size of the drain pipe 403 is slightly larger than the size of the drain port 401, so that when the drain pipe 403 is installed on the drain port 401, the drain pipe 403 will be tightly fixed in the drain port 401, reducing the occurrence of looseness or water leakage. By arranging the drain pipe 403 in the drain port 401 in an interference fit manner, the connection strength and sealing between the drain pipe and the drain port can be increased, thereby improving the reliability of drainage.

[0060] Optionally, the drain pipe 403 is arranged at the drain outlet 401 by bonding, connecting with a connector, pre-buried or integrally formed. The arrangement of the drain pipe 403 can be flexibly arranged according to actual needs.

[0061] In some embodiments, the material of the drain pipe 403 includes metal, which has good thermal conductivity and can improve the heat transfer rate between the first heat conducting plate and the second heat conducting plate. For example, the material of the drain pipe 403 is stainless steel, aluminum or copper.

[0062] Optionally, the material of the partition is the same as that of the drain pipe 403, which facilitates processing and manufacturing.

[0063] Optionally, the partition is welded or integrally formed with the hole wall of the drain pipe 403. Such an arrangement not only enables the partition to be firmly arranged at the drain outlet 401, but also ensures the heat conduction effect between the two.

[0064] In some embodiments, in combination Figure 1 As shown, the refrigeration device further includes an evaporating dish 700. The evaporating dish 700 is arranged below the water receiving tray 400, and the orthographic projections of the first drain hole and the second drain hole on the evaporating dish fall into the evaporating dish. In other words, the orthographic projections of the drain port 401 on the evaporating dish fall into the evaporating dish, and the orthographic projections of the drain pipe 403 on the evaporating dish fall into the evaporating dish.

[0065] By providing the evaporating dish 700 , the defrost water leaking from the water receiving tray 400 can be received and then evaporated by natural evaporation or heating evaporation.

[0066] Optionally, a heating wire is provided on the outer wall surface of the bottom plate of the evaporating dish 700. The heating wire is used to heat the evaporating dish 700 to evaporate the water in the evaporating dish 700. By providing the heating wire on the outer wall surface of the bottom plate, the influence of defrosting water on the heating wire can be reduced, and the service life of the heating wire can be extended.

[0067] Optionally, the evaporation dish 700 is thermally connected to a compressor so as to utilize the heat of the compressor to evaporate the water in the evaporation dish 700 .

[0068] In some embodiments, the refrigeration device further comprises a housing, which is provided with an evaporator chamber and a heat dissipation chamber provided below the evaporator chamber. The evaporator chamber and the heat dissipation chamber are separated by a first chamber wall 101. The water receiving tray 400 is provided in the evaporator chamber 100, and the compressor 200 and the evaporation dish are located in the heat dissipation chamber. The drain pipe 403 passes through the first chamber wall 101 and extends to the top of the evaporation dish 700.

[0069] By providing the evaporator chamber and the heat dissipation chamber, the influence of the components in the heat dissipation chamber on the refrigeration of the refrigeration equipment can be reduced. The drain pipe 403 passes through the first chamber wall 101 and extends to the top of the evaporation dish 700, guiding the defrost water into the evaporation dish 700, and then using the waste heat in the heat dissipation chamber to evaporate the defrost water in the evaporation dish 700, thereby improving the utilization rate of the waste heat.

[0070] Optionally, an evaporator and an evaporation fan are further provided in the evaporator chamber. A storage chamber is also provided in the housing, and the evaporator chamber is connected to the storage chamber. The temperature of the evaporator surface is relatively low, and the temperature of the airflow decreases after flowing through the surface of the evaporator, and then the airflow flows into the storage chamber to provide cooling for the storage chamber.

[0071] Optionally, the heat dissipation chamber is provided with a plurality of exhaust holes, through which the heat dissipation chamber can be connected to the external space. This arrangement facilitates the discharge of waste heat and water vapor. For example, after the defrosting water in the evaporating dish 700 evaporates, it diffuses to the external space of the refrigeration device through the exhaust holes.

[0072] Optionally, a condenser and a condensing fan are further provided in the heat dissipation chamber. In this way, it is convenient to dissipate heat for the condenser. The condensing fan rotates to drive the air flow between the heat dissipation chamber and the external space to accelerate the heat dissipation of the condenser and the diffusion of water vapor.

[0073] In some embodiments, the evaporation dish 700 is located on the top of the compressor 200. This arrangement facilitates the use of waste heat from the compressor 200 to heat the evaporation dish 700, thereby evaporating the defrosting water in the evaporation dish 700 without manual pouring of water.

[0074] In some embodiments, the evaporating dish 700 is made of metal, which has good thermal conductivity and can improve the heat conduction effect between the compressor and the evaporating dish 700, thereby increasing the evaporation rate of the defrosting water in the evaporating dish 700. For example, the evaporating dish 700 is made of stainless steel, aluminum, or copper.

[0075] In some embodiments, in combination Figure 4 As shown, the bottom surface 402 of the water receiving tray 400 is concave downward, and the first drainage hole and the second drainage hole are arranged at the lowest position of the bottom surface 402. In other words, the drain port is arranged at the lowest position of the bottom surface 402. Such arrangement facilitates the water in the water receiving tray 400 to flow to the first drainage hole and the second drainage hole and drain out of the water receiving tray 400, which is conducive to improving the water leakage effect of the water receiving tray 400.

[0076] In some embodiments, the heating element 300 is disposed at the bottom of the evaporator 100. In this way, the defrosting effect on the evaporator is improved and the arrangement is convenient.

[0077] Optionally, the refrigeration equipment includes refrigerators, freezers and cold storage cabinets, etc.
