Referring to fig. 1, a refrigeration device 400 provided in an embodiment of the present application may be a variety of devices such as a refrigerator, a freezer, a showcase, a vending cabinet, or a wine cabinet, and the refrigeration device 400 may be used for refrigerating or freezing, and simultaneously refrigerating and freezing. The refrigeration equipment 400 comprises an equipment body and a box liner assembly, wherein the equipment body is a shell of the refrigeration equipment 400, the appearance shape of the refrigeration equipment 400 is embodied, the box liner assembly is arranged inside the refrigeration equipment 400 and used as the inner wall of the refrigeration equipment 400, a foaming layer is arranged between the equipment body and the box liner assembly to insulate heat, and cold air in the refrigeration equipment 400 is prevented from being transferred to air.

The box liner assembly comprises a box liner body (not numbered in the figure) and the air duct assembly 200, the structural shape of the box liner body is adapted to that of the equipment body, the equipment body is sleeved outside the box liner body, the inner wall of the box liner body is used as the inner wall of the refrigeration equipment 400, and the box liner assembly can be used for contacting food or storing other articles in the refrigeration equipment 400. The container body can be provided with a compartment, and the air duct assembly 200 can be arranged in the container body to separate the container body into two or more compartments which are independent of each other. The number of air duct assemblies 200 disposed within the cabinet body may be determined as desired.

When the air duct assembly 200 is disposed in the container body, the air duct assembly 200 divides the accommodating space of the container body into two chambers, i.e., the first compartment 410 and the second compartment 420. The functions of the first compartment 410 and the second compartment 420 may be the same or different. When the functions of the first compartment 410 and the second compartment 420 are the same, the first compartment 410 and the second compartment 420 may each be a refrigerating compartment or a freezing compartment. When the functions of the first compartment 410 and the second compartment 420 are different, the first compartment 410 may be a refrigerating compartment and the second compartment 420 may be a freezing compartment.

The air duct assembly 200 not only has a function of circulating air supply, but also can function as a compartment. In particular, the air duct assembly 200 may include an air duct member, a drain assembly 100, an evaporator, and a partition member through which the separation of the air duct assembly 200 is primarily accomplished. The air duct component and the baffle component can be horizontally arranged on the inner wall of the box liner body, wherein the baffle component can be fixedly connected to the box liner body, and the edge of the baffle component is fixed on the inner wall of the box liner body in a gluing, clamping or fastening mode.

Since the defrosted water often carries the crushed ice which is not completely melted, the crushed ice is easily accumulated on the drain pipe 120, so that the drain pipe 120 is blocked, and furthermore, the water leakage phenomenon of the refrigerator can be caused. To this end, embodiments of the present application provide an improved drain assembly 100.

Fig. 2 is a left side view of a drain assembly 100 provided in accordance with an embodiment of the present application; FIG. 3 is an enlarged view of portion A of FIG. 2; fig. 4 is a schematic structural view of another embodiment of a drainage assembly 100 according to an embodiment of the present application; fig. 5 is an exploded view of another embodiment of a drain assembly 100 according to an embodiment of the present application.

Referring to fig. 2 to 5, it can be understood that a drainage assembly 100 according to an embodiment of the present application includes a water guide plate 110 and a drainage pipe 120.

The water guide plate 110 can receive condensed water condensed by water vapor meeting the evaporator and defrosting water generated by frost on the surface of the evaporator when meeting heat. The water falls into the water guide channel 113 and is guided to the water guide port 114 along the extending direction of the water guide channel 113, and is guided to the drain pipe 120 by the water guide port 114 to be discharged. The water guide part 115 is mainly used for guiding and supporting the drain pipe 120, so that the drain pipe 120 and the water guide port 114 are prevented from being connected shallowly and falling off, and meanwhile, condensed water and defrosting water generated when frost on the surface of the evaporator meets heat can be guided to flow into the drain pipe 120, so that water is prevented from leaking from the joint of the drain pipe 120 and the water guide port 114.

The drain pipe 120 includes interconnect's body 121 and holds body 122, and body 121 and the mutual contained angle setting of holding body 122, holds the body 122 cover and establishes in the outside of water guide part 115, and the length that water guide part 115 stretched into the inside of holding body 122 is X, wherein: x is more than or equal to 5mm and less than or equal to 25mm.

Therefore, the smooth discharge of the defrosting water can be ensured, and the water leakage phenomenon of the drain pipe 120 can be avoided.

With continued reference to fig. 2-4, it can be appreciated that the receiving body 122 includes a receiving section 1221 and a deflector wall 1222, and the deflector wall 1222 is obliquely disposed between the receiving section 1221 and the tube 121. The receiving section 1221 is sleeved outside the water guiding portion 115, that is, the projection length of the water guiding portion 115 on the receiving section 1221 is X.

The projection length of the water guiding part 115 on the receiving section 1221 is the key of the collection and discharge of the defrosting water, and the receiving section 1221 and the water guiding part 115 are nested, i.e. the water guiding part 115 extends into the receiving section 1221 for a distance, so as to ensure the effective discharge of the defrosting water, and effectively prevent the hot air outside the refrigeration equipment 400 from leaking into the refrigeration equipment 400 through the drain pipe 120.

The shape of the receiving section 1221 is adapted to the shape of the water guiding portion 115, for example, when the cross-sectional shape of the water guiding portion 115 is a semicircle, the cross-sectional shape of the receiving section 1221 is a circle. When the cross-sectional shape of the water guiding portion 115 is rectangular, the cross-sectional shape of the receiving section 1221 is also rectangular. When the cross-sectional shape of the water guiding portion 115 is triangular, the cross-sectional shape of the receiving section 1221 is also triangular. The shape of the receiving section 1221 and the shape of the water guide 115 may be arbitrarily set as long as the receiving section 1221 can be inserted outside the water guide 115 and water can be transferred from the water guide 114 to the drain pipe 120.

In the case where the receiving section 1221 is sleeved outside the water guiding portion 115, the end face of the extending flange 1224 abuts against the water guiding plate 110, and a certain gap is provided between the limiting flange 1223 and the water guiding plate 110, so that the mounting position of the drain pipe 120 can be conveniently adjusted by the limiting flange 1223.

With continued reference to fig. 4 and 5, it will be appreciated that the stop flange 1223 is provided with at least one mounting hole 1225, and that two mounting holes 1225 are illustrated in the present embodiment. The fastening member is inserted through the mounting hole 1225 to fix the position of the drain pipe 120, so that a gap between the inner wall of the receiving body 122 and the end surface of the water guide 115 is maintained, thereby improving the reliability of the drain assembly 100.

With continued reference to fig. 3 and 5, it can be appreciated that the end surface of the water guide 115 extends downwardly to provide a water guide flange 1151. The water guiding flange 1151 can be abutted against the inner wall of the receiving section 1221, so that the water at the water guiding port 114 can smoothly enter the water draining pipe 120, and meanwhile, water leakage caused by the water flowing back into the refrigeration device 400 can be avoided.
