Description

Technical Field

[0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration device. Background Art

[0002] The refrigeration function of the mainstream refrigerators on the market is mainly achieved through the evaporator and the refrigerant in the pipeline. During the use of the refrigerator, since the temperature of the evaporator is lower than the external temperature, the evaporator may condense the water vapor in the external air and frost it on the surface of the evaporator, which will produce a large amount of ice cubes on the evaporator, which will easily affect the refrigeration effect and efficiency of the refrigerator and even cause quality accidents. In order to solve the problem of evaporator frosting, a heating wire is provided on the evaporator in the prior art, and the frost is removed from the evaporator by heating it during the defrosting process. At the same time, a water receiving pan is provided directly below the evaporator, and the water receiving pan is used to receive the melted frost. The water receiving pan has a drainage channel to discharge the melted frost on the evaporator through the drainage channel.

[0003] The water receiving tray is generally arranged below the evaporator, and the cross-section of the water receiving tray is approximately an inverted cone. The water inlet of the drainage channel is generally located at the lowest position of the water receiving tray. The heating wire is wrapped inside the evaporator to provide heat to the outer surface of the evaporator. After receiving the heat, the frost on the outside of the evaporator melts. The water receiving tray is used to collect the water dripping when the frost on the outer surface of the evaporator melts. The water falling into the water receiving tray slides along the surface of the water receiving tray to the water inlet of the drainage channel and is discharged to the outside of the refrigerator through the drainage channel.

[0004] In actual use, there is often some large frost that falls from the evaporator and blocks the drainage channel of the water tray, which can easily cause the drainage channel to not completely melt the ice. Over time, the drainage channel will be blocked by ice, affecting the defrosting effect. Summary of the invention

[0012] Furthermore, the drainage hole is a tapered hole penetrating the enclosure, and the diameter of the drainage hole decreases from the water collection trough toward the trough body.

[0013] Further, the drainage hole comprises a first drainage hole and a second drainage hole provided on two opposite side walls of the enclosure;

[0014] The bottom of the disk body also has a first guide surface for guiding the flow toward the first drainage hole and a second guide surface for guiding the flow toward the second drainage hole.

[0015] Furthermore, the disk body has a length direction and a width direction, and the first guide surface and the second guide surface are arranged oppositely on both sides of the boss along the length direction.

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] An embodiment of the present invention discloses a water receiving tray assembly for refrigeration equipment. 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 below the evaporator to carry the frost that falls after the evaporator is defrosted. In order to solve the problem of frost on the evaporator, a heating wire is provided on the evaporator in the prior art. During the defrosting process, the heating wire is used to heat the frost to remove the frost from the evaporator. However, if the frost that falls into the water receiving tray is large, it will accumulate in the water receiving tray. The accumulated large ice blocks are difficult to melt and easily cause the drainage channel to be blocked.

[0038] The water receiving pan assembly for refrigeration equipment disclosed in the present application is as follows Figure 1 -8, comprising: a disk body 1 having a water collecting trough 10 and a drainage channel 2 connected to the water collecting trough 10; the drainage channel 2 connects the water collecting trough 10 with the outside, the water collecting trough 10 is used to carry the ice water after the evaporator defrosts, and the ice water after the evaporator defrosts is collected in the water collecting trough 10 and then discharged through the drainage channel 2.

[0039] In this embodiment, the bottom of the disk body 1 is formed with an upwardly protruding boss 11 and a groove body 12 formed on the boss 11 and opened in a direction away from the water collecting trough 10. The drainage channel 2 includes a drainage hole 21 connecting the water collecting trough 10 and the groove body 12. The drainage hole 21 is arranged on the side wall of the boss 11.

[0040] An evaporator 100 is arranged above the tray body 1, and a heating element 200 is arranged between the evaporator 100 and the tray body 1. The heating element 200 is connected in series with a heating wire arranged beside the evaporator 100. The heating wire beside the evaporator 100 is used to heat the outer surface of the evaporator 100 to defrost the frost on the outer surface of the evaporator 100. Large pieces of frost falling from the outer surface of the evaporator 100 are received by the tray body 1 after falling, gathered in the water collection trough 10, and then discharged through the drainage channel 2. If there are large pieces of frost, it is easy to form ice blockage in the water collection trough 10. The heating element 200 arranged above the water collection trough 10 can heat the frost gathered in the water collection trough 10, accelerate the melting of the frost, and thus alleviate the ice blockage.

[0041] In the prior art, a drainage hole is generally provided directly in the low-lying part of the disk body 1, and frost water is directly discharged outward from the drainage hole. In the present embodiment, an upwardly protruding boss 11 is creatively formed at the bottom of the disk body 1, and the drainage hole 21 is provided on the side wall of the boss 11. The drainage hole 21 is provided on the side wall of the boss 11 near the top. The advantage of such a setting is that the boss 11 lifts the drainage hole 21, so that the drainage hole 21 is located closer to the heating element 200, thereby better alleviating the ice blockage near the drainage hole 21.

[0042] In addition, compared with providing a downwardly recessed drainage channel at this position, providing the boss 11 can reduce the gathering of ice cubes near the drainage hole 21. The elevation of the boss 11 can simultaneously elevate the drainage hole 21 and also extend the drainage hole 21 in the lateral direction, which is not conducive to the accumulation of frost in the drainage hole 21. In the prior art, the drainage hole is generally formed directly at the bottom of the tray body 1, which is more likely to cause frost to be blocked in the drainage hole.

[0043] In a specific embodiment, the heating wire emits heat after being powered on. At this time, the evaporator 100 senses the heat of the heating wire, and the frost attached to the outer surface of the evaporator 100 begins to melt. The melted frost drops into the water collection groove 10 of the tray body 1 and is discharged to the outside of the refrigerator from the drainage channel 2. At the same time, some larger ice cubes become loosely connected to the evaporator due to the heat. Under the action of gravity, part of the whole ice cube will fall off. Under the action of gravity, the ice cubes will fall into the water collection groove 10 and flow along the bottom of the water collection groove 10 to the drainage channel 12. At this time, since a boss 11 protruding upward is formed at the bottom of the disk body 1, the boss 11 lifts the drainage channel 12, and at the same time, the boss 11 can support large pieces of ice, and play a certain blocking role in blocking the ice from clogging the drainage channel 12, resulting in large pieces of ice being unable to enter the drainage channel 12. At the same time, due to the close contact between the ice and the heating element 200, the ice will be exposed to a large amount of heat and quickly melt into water. The melted water can smoothly enter the groove body 12 from the drainage hole 21, and finally be discharged to the outside of the refrigerator through the groove body 12.

[0044] like Figure 2 As shown, the drainage hole 21 flows the water in the water collection tank 10 to the tank body 12, and the drainage channel 2 also includes a water outlet 13 arranged at the bottom of the plate body 1 and located at the outlet of the tank body 12; the water outlet 13 flows the water in the tank body 12 outward. The water outlet 13 is formed on the plate body 1 and is located at the lowest place of the plate body 1. The water outlet 13 can be directly opened on the plate body 1. The boss 11 is formed by protruding upward from the edge of the water outlet 13.

[0045] Specifically, Figure 7 -8, the boss 11 includes a cover plate 111 arranged above the water outlet 13 and a surrounding plate 112 for supporting the cover plate 111, the surrounding plate 112 is arranged at the edge of the water outlet 13, and the trough body 10 is surrounded by the surrounding plate 112 and the cover plate 111; the drainage hole 21 is arranged on the surrounding plate 112.

[0046] 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 enclosure 112 is a circular ring body connected between the disc body and the cover plate. The enclosure 112 is arranged at the edge of the water outlet 13, and the enclosure 112 is directly fixed on the disc body 1.

[0047] As a preferred solution, the size of the cover plate 111 can be larger than the size of the water outlet 13. Such a structural setting can make the enclosure 112 be set at an angle. The cover plate 111 extending out of the water outlet 13 can block the falling frost, thereby more effectively avoiding the accumulation of frost at the position of the drainage hole 21 and causing blockage of the drainage hole 21.

[0048] Furthermore, since the setting of the drain hole 21 will connect the outside with the chamber where the evaporator 100 is located, it is easy to cause the outside air to enter the evaporator 100, thereby affecting the evaporation efficiency in the evaporator 100. In order to reduce the impact of the outside air on the evaporator 100, the drain hole 21 is set as a tapered hole that penetrates the enclosure 112, and the hole diameter of the drain hole 21 decreases from the water collection tank 10 to the tank body 12.

[0049] In the above structure, the drain hole 21 is set as a tapered hole, and the diameter of the tapered hole gradually decreases when facing the outside, so that the structure can easily realize the drainage of the drain hole 21, but it has a good blocking effect on the entry of outside air. When draining, it enters from the large hole and drains from the small hole, but when the outside air enters the drain hole 21, it needs to enter from the small hole but exit from the large hole, which is obviously not conducive to the entry of outside air.

[0050] In addition, in the present embodiment, the drain hole 21 is configured as a conical hole, and an inclined hole wall is formed on the side wall of the drain hole 21. The hole wall is a slope, and the inclined hole wall has a larger area than the hole wall of the vertical enclosure 112. The larger area can accumulate some water on the hole wall at the drain outlet. After the drainage is completed, this part of the accumulated water can quickly form ice near the drain hole 21 during the cooling process of the evaporator. The formation of the ice is actually a blockage of the drain hole 21, which can better prevent outside air from entering the compartment where the evaporator is located, thereby better improving the cooling efficiency of the evaporator.

[0051] like Figure 5 As shown, in this embodiment, the tray body 1 is in 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 arrangement of the above structure can facilitate the frost to gather at the low-lying water outlet 13. Since the cross section of the evaporator 100 is roughly rectangular, the cross section of the tray body 1 has a rectangular structure that matches the evaporator 100. The tray body 1 has a length direction and a width direction, the length direction is the left-right direction, and the width direction is the front-back 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 in the left-right direction, so the tray body 1 is also extended in the left-right direction.

[0052] The conical structure of the disk body 1 is an asymmetric conical structure, that is, the lowest point of the cone is not at the center of the disk body 1. In the present embodiment, the lowest point of the cone is located on the left side in the left-right direction, so that two first guide surfaces 14 and second guide surfaces 15 with different slopes are formed at the bottom of the disk body 1. The first guide surface 14 and the second guide surface 15 are arranged on both sides of the boss 11 in a relative manner along the length direction. The first guide surface 14 and the second guide surface 15 are used to guide the water flow to the drainage channel 2.

[0053] In order to better achieve drainage, the drainage hole 21 includes a first drainage hole and a second drainage hole arranged on the opposite side walls of the enclosure 112; the first guide surface 14 is used to guide the flow toward the first drainage hole, and the second guide surface 15 is used to guide the flow toward the second drainage hole.

[0054] The slope of the first guide surface 14 is greater than the slope of the second guide surface 15. That is, the vertical height of the first guide surface 14 increases as it moves away from the boss 11; the vertical height of the second guide surface 15 increases as it moves away from the boss 11. The above structure makes the flow velocities on both sides inconsistent when the water flows converge to the drainage channel 2, which can avoid the collision of the water flows on both sides at the inlet position of the drainage channel 12, resulting in poor drainage.

[0055] Another embodiment of the present invention is Fig. 9 -12 also discloses a refrigeration device, including a box body, on which is disposed an inner tank 300, an evaporator 100 disposed in the inner tank 300, a heating wire and the water receiving tray assembly, the water receiving tray assembly being disposed on the lower side of the evaporator 100, the heating wire being disposed on the side of the evaporator 100, the refrigeration device also having a heating element 200 disposed between the evaporator 100 and the water receiving tray assembly, the heating element 200 being a tubular heating element, and the heating element 200 and the heating wire being connected in series.

[0056] In order to better protect the heating element 200, a protective baffle 400 is further provided between the evaporator 100 and the heating element 200. The protective baffle 400 is used to protect the heating element 200, and can effectively prevent the large ice cubes falling from the evaporator 100 from damaging the heating element 200.

[0057] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
