The water receiving tray assembly can be used in refrigerators, freezers, wine cabinets and other refrigeration equipment. The water receiving tray assembly is placed in the refrigerator and located at the evaporation The bottom of the container is used to bear the frost that falls after the evaporator defrosts. In order to solve the frosting problem of the evaporator, a heating wire is provided on the evaporator in the prior art, and the heating wire is used to heat the evaporator during the defrosting process to remove the frost from the evaporator. However, if the frost falling in the water receiving tray has large pieces of ice, it will accumulate in the water receiving tray, and it is difficult to melt the accumulated large ice pieces, which may easily cause blockage of the drainage channel.

The water receiving tray assembly for refrigeration equipment disclosed in the present application is shown in Figures 1-8, comprising: a tray body 1 with a sump 10 and a drain channel 2 communicating with the sump 10; the drain channel 2 communicates with The water collection tank 10 is connected with the outside world, and the water collection tank 10 is used to carry the ice water after the evaporator has defrosted.

In this embodiment, the bottom of the disc body 1 is formed with an upwardly protruding boss 11 and a groove body 12 formed on the boss 11 and opening in a direction away from the water collection tank 10. The channel 2 includes a drainage hole 21 connecting the sump 10 and the tank body 12 , and the drainage hole 21 is arranged on the side wall of the boss 11 .

An evaporator 100 is arranged above the plate body 1, and a heating element 200 is arranged between the evaporator 100 and the plate body 1. The heating element 200 is connected in series with the heating wire arranged on the side of the evaporator 100. The heating wire on the side is used to heat the outer surface of the evaporator 100 to defrost the frost on the outer surface of the evaporator 100 . The large pieces of frost falling from the outer surface of the evaporator 100 are picked up by the tray body 1 after they fall, accumulate in the sump 10, and then be discharged through the drainage channel 2. If there are large pieces of frost, it is easy to form ice in the sump 10 Blocking. The heating element 200 provided above the sump 10 can heat the frost accumulated in the sump 10 to accelerate the melting of the frost, thereby alleviating ice blockage.

In the prior art, drainage holes are generally provided directly in the low-lying places of the tray body 1, and the frosty water is directly discharged from the drainage holes. In this embodiment, an upwardly protruding boss 11 is creatively formed on the bottom of the tray body 1. And the drainage hole 21 is arranged on the side wall of the boss 11, the drainage hole 21 is arranged on the side wall of the boss 11 near the position of the top, the benefit of setting like this is to make the boss 11 form a lift to the drainage hole 21, so that The drain hole 21 is located closer to the heating element 200 , so that the situation of ice blockage near the drain hole 21 can be better alleviated.

In addition, setting the boss 11 can reduce the accumulation of ice cubes near the drain hole 21 compared to setting the drainage channel recessed downward at this position, and the lifting of the boss 11 can lift the drain hole 21 at the same time and can also increase the amount of drainage. 21 is extended along the transverse direction, which is not conducive to the accumulation of frost in the drain hole 21 . In the prior art, drain holes are generally formed directly at the bottom of the tray body 1, which is more likely to cause congestion of the drain holes by frost.

In a specific embodiment, the heating wire will emit heat after it is energized. At this time, the evaporator 100 feels the heat from the heating wire, and the frost attached to the outer surface of the evaporator 100 begins to melt, and the water after the melting of the frost drops onto the plate. In the sump 10 of body 1, the outside of the refrigerator is discharged from the drainage channel 2. At the same time, some larger ice cubes become loose due to the connection with the evaporator after being heated. Under the action of gravity, part of the whole ice cubes will fall off. Under the action of gravity, the ice cubes will fall into the sump 10 and slide down to the drainage channel 12 along the bottom of the sump 10. The drainage channel 12 is lifted, and the boss 11 can support the large ice cubes at the same time, which can block the blockage of the ice cubes to the drainage channel 12, so that the large ice cubes cannot enter the drainage channel 12. At the same time, due to the close contact between the ice cube and the heating element 200, the ice cube will receive a lot of heat and melt into water quickly. The melted water can smoothly enter the tank body 12 from the drain hole 21, and finally be discharged through the tank body 12 The exterior of the refrigerator.

As shown in FIG. 2 , the drainage hole 21 flows the water in the sump 10 to the tank body 12 , and the drainage channel 2 also includes a water outlet arranged at the bottom of the tray body 1 and at the outlet of the tank body 12 13 ; the water outlet 13 flows out the water in the tank body 12 . The water outlet 13 is formed on the tray body 1 and is located at the lowest point of the tray body 1 . The water outlet 13 can be directly opened on the tray body 1 . The boss 11 protrudes upward from the edge of the water outlet 13 .

Specifically, as shown in Figures 7-8, the boss 11 includes a cover plate 111 arranged above the water outlet 13 and a surrounding plate 112 for supporting the covering plate 111, and the surrounding plate 112 is arranged on The edge of the water outlet 13 , the tank body 10 is surrounded by the surrounding board 112 and the covering board 111 ; the drainage hole 21 is arranged on the surrounding board 112 .

In this embodiment, the cover plate 111 is adapted to the shape of the water outlet 13, the cover plate 111 is a disc body adapted to the water outlet 13, and the surrounding plate 112 is connected An annular body between the disc body and the cover plate. The surrounding plate 112 is arranged on the edge of the water outlet 13 , and the surrounding plate 112 is directly fixed on the disc body 1 .

As a preferred solution, the size of the cover plate 111 can be larger than the size of the water outlet 13, so that the setting of the structure can make the surrounding plate 112 be inclined, and the cover plate 111 can be extended out of the water outlet 13 to block the falling frost. , and then can more effectively avoid the accumulation of ice and frost at the position of the drain hole 21 , causing the blockage of the drain hole 21 .

Furthermore, since the setting of the drainage hole 21 will communicate with the outside world and the chamber where the evaporator 100 is located, it is easy to cause the outside air to enter the evaporator 100 and affect the evaporation efficiency in the evaporator 100 . In order to reduce the influence of the outside air on the evaporator 100, the drain hole 21 is set as a tapered hole penetrating through the surrounding plate 112, and the diameter of the drain hole 21 decreases from the sump 10 to the tank body 12. .

In the setting of the above-mentioned structure, the drain hole 21 is set as a tapered hole, and the aperture of the tapered hole is gradually reduced when facing the outside, so that the setting of the structure can realize the drainage of the drain hole 21 conveniently, but the entry of the outside air Play a good blocking role. When draining, enter the small hole drainage from the large hole, but when the external air enters the drain hole 21, it needs to enter from the small hole but come out from the large hole, which is obviously not conducive to the entry of the external air.

In addition, in the present embodiment, the drainage hole 21 is set as a tapered hole, and an inclined hole wall is formed on the side wall of the drainage hole 21. The hole wall is an inclined plane, and the hole wall of the inclined plane is compared with the hole of the vertical shroud 112. The area of the wall is larger, and the larger area can accumulate part of the water on the wall of the drain hole. This part of the accumulated water can quickly form ice near the drain hole 21 during the cooling process of the evaporator after the drain is completed. The formation of the ice seal is actually the sealing of the drainage hole 21, which can better prevent the outside air from entering the compartment where the evaporator is located, thereby better improving the cooling efficiency of the evaporator.

As shown in Figure 5, in this embodiment, the tray body 1 has a conical structure as a whole, and the water outlet 13 of the drainage channel 12 is arranged at the lowest part of the conical structure. The positions of the water outlets 13 converge, and since the cross-section of the evaporator 100 is approximately rectangular, the cross-section of the tray 1 has a rectangular structure that matches the evaporator 100, and the tray 1 has a longitudinal direction and the width direction, the length direction is the left-right direction, and the width direction is the front-rear direction. The specific shape of the tray body 1 is adapted to the shape of the evaporator. The cross-section of the evaporator in the prior art is rectangular and extends along the left and right directions, so the tray body 1 also extends along the left and right directions.

The conical structure of the disc body 1 is an asymmetrical conical structure, that is, the lowest point of the conical shape is not at the center of the disc body 1. In this embodiment, the lowest position of the conical shape is on the left side in the left-right direction. This causes the bottom of the tray body 1 to form two first guide surfaces 14 and second guide surfaces 15 with different slopes, and the first guide surface 14 and the second guide surface 15 are arranged oppositely along the length direction. On both sides of the boss 11 , the first guide surface 14 and the second guide surface 15 are used to guide the water flow to the drainage channel 2 .

In order to better realize drainage, the drainage hole 21 includes a first drainage hole and a second drainage hole arranged on the opposite side walls of the shroud 112; the first guide surface 14 is used to The flow is guided in the direction of the drainage hole, and the second guide surface 15 is used to guide the flow in the direction of the second drainage hole.

Wherein, the slope of the first guiding surface 14 is greater than the slope of the second guiding surface 15 . That is to say, the vertical height of the first guide surface 14 increases with the direction away from the boss 11; the vertical height of the second guide surface 15 increases with the direction away from the boss 11. big. The setting of the above-mentioned structure makes the flow velocity on both sides inconsistent when the water flow converges to the drainage channel 2, which can avoid the hedging of the water flow on both sides at the inlet position of the drainage channel 12, resulting in poor drainage.

Another embodiment of the present invention, as shown in FIGS. 9-12 , also discloses a refrigeration device, including a box body, on which an inner tank 300, an evaporator 100 arranged in the inner tank 300, a heating wire and the water tray assembly, the water tray assembly is arranged on the lower side of the evaporator 100, the heating wire is arranged on the side of the evaporator 100, and the refrigeration equipment also has The heating element 200 between the evaporator 100 and the water tray assembly, the heating element 200 is a tubular heating element, and the heating element 200 is connected in series with the heating wire.
