[0029] The present invention will be described in detail below with reference to various embodiments shown in the accompanying drawings.

[0030] In various drawings of the present invention, for the sake of convenience of illustration, some sizes of structures or parts are exaggerated relative to other structures or parts, and thus, only the basic structure of the subject matter of the present invention is illustrated.

[0031] It should be understood that although the terms first, second, etc. may be used in this document to describe various elements or structures, these described objects should not be limited by these terms. These terms are only used to distinguish these described objects from each other.

[0032] See also Figures 1 to 3 An embodiment of the present invention provides a refrigeration device 100, including a housing 1, wherein the housing 1 defines a refrigeration chamber 11 and a compressor chamber 12, wherein a water receiving pan 121 is provided in the compressor chamber 12, and the water receiving pan 121 can receive condensed water or defrost water discharged from the refrigeration chamber 11.

[0033] The refrigeration device 100 may specifically be a refrigerator, a freezer, a wine cabinet, etc. The refrigeration compartment 11 may include at least one of a refrigeration compartment, a freezing compartment, and a temperature-changing compartment, and the number of each compartment may be only one, or two, or even more.

[0034] In this embodiment, the refrigeration compartment 11 includes a refrigerator compartment and a freezer compartment.

[0035] For ease of description, in this embodiment, the refrigeration device 100 is horizontally placed on the ground as an example for description, and the direction from the ground toward the refrigeration device 100 is defined as the bottom-up direction. In this embodiment, the water tray 121 is located below the refrigeration compartment 11.

[0036] Furthermore, the refrigeration device 100 further includes a drainage assembly 200 , which is connected to the refrigeration compartment 11 and the water receiving pan 121 , so as to discharge condensed water or defrosted water discharged from the refrigeration compartment 11 to the water receiving pan 121 via the drainage assembly 200 .

[0037] The water receiving tray 121 is preferably an evaporating dish, so that the condensed water or defrosted water in the evaporating dish can be evaporated to dissipate heat for the condenser, thereby improving the heat dissipation capacity and heat dissipation efficiency of the refrigeration system.

[0038] See also Figures 4 to 5 The drainage assembly 200 provided in one embodiment of the present invention comprises an upper water pipe 2, a lower water pipe 3, and an adapter 4 connecting the upper water pipe 2 and the lower water pipe 3. The adapter 4 comprises a water inlet 41 communicating with the upper water pipe 2 and a water outlet 42 communicating with the lower water pipe 3. The cross section of the water outlet 42 is larger than that of the water inlet 41. Thus, when the drainage assembly 200 is used to discharge the condensed water and defrost water in the refrigeration compartment 11 to the compressor compartment 12, the hot air entering the refrigeration compartment 11 from the compressor compartment 12 through the drainage assembly 200 will be reduced, so as to avoid additional increase in the energy consumption of the refrigeration device 100, which is beneficial to energy saving and environmental protection.

[0039] Specifically, the upper water pipe 2 is connected to the refrigeration compartment 11; the lower water pipe 3 is connected to the water receiving pan 121, or the lower end of the lower water pipe 3 is located above the water receiving pan 121, so that the condensed water or defrosted water generated in the refrigeration compartment 11 can be discharged into the water receiving pan 121 to prevent the condensed water or defrosted water from being accumulated in the refrigeration compartment 11 for a long time, thereby affecting the storage effect of the food in the refrigeration compartment 11.

[0040] See also Figures 6 to 11 Preferably, the water outlet 42 is in a strip shape. In this way, when the condensed water or defrosting water flows to the adapter 4, the water outlet cross-sectional area through which the water can flow becomes smaller. Under the action of the water flow tension, the water outlet 42 is equivalent to being water-sealed, which can prevent the air in the compressor compartment 12 from entering the upper water pipe 2 through the water outlet 42 and then entering the refrigeration compartment 11. In addition, it can also prevent the cold air in the refrigeration compartment 11 from entering the lower water pipe 3 through the water outlet 42 and then entering the compressor compartment 12, thereby causing an additional increase in energy consumption, and avoid noise caused by air in the water flow.

[0041] Preferably, the adapter 4 is a flexible part, which can increase the friction force when the adapter 4 is assembled with the upper water pipe 2 and the lower water pipe 3, thereby improving the strength of the connection. On the other hand, the adapter 4 can be deformed appropriately according to the water flow rate. When the water flow rate is small, the water outlet 42 can have a good water sealing effect. When the water flow rate is large, the water outlet cross-section of the water outlet 42 can be enlarged, thereby improving the drainage efficiency.

[0042] In this embodiment, the adapter 4 is preferably a rubber member.

[0043] See also Figure 6 The adapter 4 includes a cylinder 43, which includes a first section 431 and a second section 432 connected to each other. The water inlet 41 is located in the first section 431 and at one end of the first section 431 away from the second section 432. The water outlet 42 is located in the second section 432 and at one end of the second section 432 away from the first section 431.

[0044] Preferably, the first section 431 is cylindrical so as to be matched with the upper water pipe 2, and the second section 432 has an inclined surface 4321 extending from the first section 431 to the water outlet 42. This can reduce the contact between the cold air in the refrigeration compartment 11 and the hot air in the compressor compartment 12, thereby reducing energy consumption.

[0045] Preferably, the cross section of the water outlet 42 is a rectangle, and the length of the rectangle is equal to the diameter of the first section 431 , and the width of the rectangle is 0.2 to 3 mm, preferably 0.2 to 1 mm.

[0046] In this embodiment, the water supply pipe 2 is inserted into the first section 431, that is, the first section 431 surrounds the outer periphery of the water supply pipe 2. Since the adapter 4 is a flexible component, the adapter 4 and the water supply pipe 2 can be sealed. In other embodiments, the water supply pipe 2 can also be arranged to be sleeved on the outer periphery of the first section 431.

[0047] See also Figure 10 to Figure 11 Preferably, in this embodiment, there are two inclined surfaces 4321, and the two inclined surfaces 4321 are symmetrically arranged along the central axis of the first section 431. The two inclined surfaces 4321 respectively surround the water outlet 42 at one end away from the first section 431, so that the contact between the cold air in the refrigeration chamber 11 and the hot air in the compressor chamber 12 can be further reduced, and it is convenient for processing.

[0048] In other embodiments, a plurality of inclined surfaces 4321 may be provided, and the cross section of the water outlet 42 may be smaller than the cross section of the water inlet 41. Preferably, the plurality of inclined surfaces 4321 are evenly distributed along the circumferential direction of the first section 431.

[0049] See also Figure 6 to Figure 7Furthermore, the inclined surface 4321 is provided with an exhaust hole 44. Through the setting of the exhaust hole 44, on the one hand, the refrigeration chamber 11 and the compressor chamber 12 can be connected to prevent the air pressure in the refrigeration chamber 11 from being too low or even forming a negative pressure, which causes the door body of the refrigeration device 100 to be unable to open during drainage; on the other hand, when the cold air enters the upper water pipe 2 along with the condensed water or the defrosted water, the gas can be discharged through the exhaust hole 44 to achieve gas-liquid separation to avoid noise.

[0050] See also Fig. 9 and Fig.10 Furthermore, the adapter 4 further includes a limiting rib 45 provided on the outer wall of the cylinder 43, and the limiting rib 45 and the cylinder 43 together form a limiting groove 46 opening toward the down pipe 3, and the down pipe 3 is fitted into the limiting groove 46 to achieve the matching of the down pipe 3 and the adapter 4. That is, the down pipe 3 is sleeved on the outer periphery of the second section 432 and is fastened from the outside by the limiting rib 45. Since the adapter 4 is a flexible member, the limiting rib 45 and the second section 432 have a large friction resistance, so that the down pipe 3 and the adapter 4 can be closely matched.

[0051] Preferably, the limiting rib 45 is formed around the outer circumference of the cylinder 43, which can further increase the friction between the limiting rib 45 and the down pipe 3, thereby further improving the fitting firmness of the down pipe 3 and the adapter 4.

[0052] See also Figure 6 to Figure 7 Furthermore, the limiting rib 45 is provided with a downwardly opening notch 461, and the notch 461 gradually becomes larger from the end close to the water inlet 41 toward the water outlet 42, that is, from top to bottom. In this way, the assembly resistance when the downpipe 3 and the adapter 4 are connected can be reduced.

[0053] Compared with the prior art, the drainage assembly 200 provided by the present invention and the refrigeration device 100 having the same have the following beneficial effects: the present invention sets the cross-section of the water outlet 42 to be larger than the cross-section of the water inlet 41. When the drainage assembly 200 is used to discharge the condensed water and defrosted water in the refrigeration chamber 11 to the compressor chamber 12, the hot air entering the refrigeration chamber 11 from the compressor chamber 12 through the drainage assembly 200 will be reduced, so as to avoid additional increase in the energy consumption of the refrigeration device 100, which is beneficial to energy saving and environmental protection; by setting the water outlet 42 to be long and strip-shaped, when the condensed water or defrosted water flows to the adapter 4, the water outlet cross-sectional area available for the water flow to flow through becomes smaller, and under the action of the water flow tension, the water flow tension is reduced. When the water outlet 42 is water-sealed, the air in the compressor chamber 12 can be prevented from entering the upper water pipe 2 through the water outlet 42 and then entering the refrigeration chamber 11. In addition, the cold air in the refrigeration chamber 11 can be prevented from entering the lower water pipe 3 through the water outlet 42 and then entering the compressor chamber 12, thereby causing an additional increase in energy consumption, and avoiding noise caused by air in the water flow. By setting the adapter 4 as a flexible part, on the one hand, the friction force when the adapter 4 is assembled with the upper water pipe 2 and the lower water pipe 3 can be increased, and the joint strength can be improved. On the other hand, the adapter 4 can be deformed appropriately according to the water flow rate. When the water flow rate is small, the water outlet 42 can have a good water sealing effect, and when the water flow rate is small, the water outlet 42 can have a good water sealing effect. When the flow rate is large, the water outlet cross-section of the water outlet 42 can be enlarged, thereby improving the drainage efficiency; the first section 431 of the adapter 4 is cylindrical, so that it is easy to match with the upper water pipe 2, and the second section 432 has a slope 4321 extending from the first section 431 to the water outlet 42, which can reduce the contact between the cold air in the refrigeration room 11 and the hot air in the compressor compartment 12, thereby reducing energy consumption; by providing two slopes 4321 and the two slopes 4321 are symmetrically arranged along the central axis of the first section 431, the contact between the cold air in the refrigeration room 11 and the hot air in the compressor compartment 12 can be further reduced, and it is easy to process; the exhaust hole 44 opened by the slope 4321 can be connected to the system The cold room 11 and the compressor compartment 12 can prevent the air pressure in the refrigeration room 11 from being too low or even forming a negative pressure, which would cause the door of the refrigeration device 100 to be unable to open when draining water. When the cold air enters the upper water pipe 2 along with the condensed water or the defrosted water, the gas is discharged through the exhaust hole 44 to achieve gas-liquid separation to avoid noise. By means of the limiting ribs 45 provided on the outer wall of the cylinder 43, the limiting ribs 45 and the second section 432 can have a larger friction resistance, thereby achieving a tight fit between the down pipe 3 and the adapter 4. By means of the notch 461 on the limiting rib 45 and the notch 461 gradually becoming larger from top to bottom, the assembly resistance when the down pipe 3 and the adapter 4 are matched can be reduced.
