The refrigerator defrosting water draining joint provided by the embodiment of the invention comprises a joint body 1 made of elastic sealing materials, wherein the joint body 1 is internally provided with water passing holes 2 penetrating through the upper end surface and the lower end surface of the joint body 1, the upper end of the joint body 1 is provided with a clamping part 4 used for clamping with a water draining port 31 of a refrigerator liner 3, and the lower end of the joint body 1 is provided with a sleeve joint part 6 used for sleeving a water draining pipe 5.

As shown in fig. 2 and 3, the upper end of the joint body 1 is provided with a clamping portion 4, the clamping portion 4 is clamped with the water outlet 31 of the refrigerator liner 3 to fix the joint body 1 and the refrigerator liner 3, meanwhile, the joint body 1 is made of elastic sealing material, so that the joint of the joint body 1 and the refrigerator liner 3 is sealed, and then the joint body is connected with the water drain pipe 5 through the sleeve joint portion 6 arranged at the lower end of the joint body 1, so that the installation of the refrigerator defrosting water drain joint is completed. Like this, when the installation, with joint portion 4 and the outlet 31 joint of refrigerator inner bag 3, the joint body 1 that elastic sealing material made is sealed fixed with refrigerator inner bag 3, compares prior art, adopts the fixed mode of no sticky tape, and the assembly action is simple, has improved production efficiency, simultaneously, has avoided the sticky tape too few to lead to sealed not tight or the sticky tape too much leads to the problem that the foaming material delaminating.

In order to facilitate the joint body 1 to be fixed with the refrigerator inner container 3 in a clamping manner, as an implementation mode, the clamping portion 4 can be a clamping hook arranged at the upper end of the joint body 1, the clamping hook can be integrally formed with the joint body 1 and has elasticity, and therefore when the refrigerator inner container is installed, the clamping hook can deform and penetrate through the water outlet 31 due to the elasticity, and then can be clamped with the edge of the water outlet 31 in a matching manner, so that the joint body 1 is fixed with the refrigerator inner container 3. As another embodiment, as shown in fig. 4, the clamping portion 4 includes a flange 41 and a limiting protrusion 42 formed at the upper end of the connector body 1, the flange 41 and the limiting protrusion 42 are arranged at intervals, the flange 41 and the limiting protrusion 42 are respectively used for matching with the upper surface and the lower surface of the liner at the edge of the drain opening 31 to prevent the drain connector from moving along the axial direction, and the outer wall of the connector body 1 between the flange 41 and the limiting protrusion 42 is used for matching with the inner wall of the drain opening 31 to prevent the drain connector from moving along the radial direction. The flange 41 is matched with the upper surface of the water outlet 31, the limiting bulge 42 is matched with the lower surface of the water outlet 31, the inner wall of the refrigerator liner 3 is clamped between the flange 41 and the limiting bulge 42, and further the water discharge connector can be prevented from moving along the axial direction, compared with a clamping and fixing mode, the flange 41 is not easy to deform, meanwhile, the limiting bulge 42 can deform when the water discharge connector is installed due to the fact that the connector body 1 is made of elastic sealing materials, so that the connector body 1 can be smoothly installed in the water outlet 31, and the outer wall of the connector body 1 between the flange 41 and the limiting bulge 42 is matched with the inner wall of the water outlet 31, and the water discharge connector can be prevented from moving along the. In addition, spacing arch 42 can be around the annular arch that connects body 1 outer wall to set up, or around connecting a plurality of archs that body 1 outer wall evenly distributed, and wherein, annular arch is for a plurality of archs, is difficult for taking place deformation, and spacing fixed stability is good.

In order to seal the outer wall of the joint body 1 and the inner wall of the drain port 31, interference fit is selected as a fitting method, and smooth installation can be ensured by utilizing the elastic sealing material property of the joint body 1. Further, as shown in fig. 4, the flange 41 has a radial width larger than that of the stopper projection 42, so that the stopper projection 42 can be inserted through the drain opening 31 to engage the joint body 1 with the drain opening 31 when the joint body 1 is mounted. Of course, the flange 41 may be smaller than the stopper projection 42 in the radial direction, and the flange 41 may be inserted through the drain opening 31 to engage the joint body 1 with the drain opening 31 when the joint body 1 is attached. However, the clamping stability of the flange 41 or the limiting protrusion 42 with a smaller radial width is not high, and the foaming material of the inner container of the refrigerator is filled and foamed at a part extending downward close to the limiting protrusion 42, so that the clamping stability of the area can be enhanced by the foaming material, therefore, in the above two schemes, the scheme that the flange 41 is larger than the radial width of the limiting protrusion 42 is preferred, the foaming material is subsequently filled around the limiting protrusion 42, and the clamping of the joint body 1 and the water outlet 31 is more stable.

In order to facilitate the joint body 1 to be matched and clamped with the water outlet 31, as shown in fig. 4, an annular protrusion 411 is formed on the lower surface of the flange 41, an annular groove 32 is formed on the inner container of the refrigerator corresponding to the annular protrusion, and the annular protrusion 411 is arranged in the annular groove 32 in a matched manner, so that a positioning and guiding effect can be achieved, and the joint body 1 and the water outlet are smoothly matched and clamped.

When the refrigerator defrosts, the ice blocks which are not completely melted frequently directly slide to the water outlet 31, so that the water outlet 31 is possibly blocked, and then defrosted water cannot be discharged in time, and in order to avoid the problem, referring to fig. 5, a support protrusion 11 is arranged on the upper end surface of the joint body 1 close to the water through hole 2. Thus, when ice falls down to the water outlet 31, the supporting protrusions 11 can lift the ice and leave a passage for water drainage, so that the water outlet 31 is not blocked.

The supporting protrusions 11 are provided to hold up the ice cubes so that the ice cubes do not block the water discharge opening 31, as long as the supporting protrusions 11 can hold up the ice cubes smoothly so that the water discharge opening is not blocked, and the specific shape and number thereof are not limited, for example, as shown in fig. 5, the supporting protrusions 11 are plural and uniformly distributed around the circumference of the water passing hole 2. The plurality of support protrusions 11 which are unevenly distributed inevitably have the problem that ice cubes with larger volume cannot be smoothly supported between two certain support protrusions 11 with larger intervals, the gaps between the support protrusions 11 which are evenly distributed are even, the sizes of the ice cubes which can be supported at all positions of the periphery of the water outlet 31 are consistent, and the stability of the structure is good.

Drain pipe 5 cup joints with cup joint portion 6, need to accomplish fine sealed, can make cup joint portion 6 and drain pipe 5 interference fit, and whole cup joint portion 6 all with drain pipe 5 interference fit, it is necessary when installing comparatively hard, therefore, as shown in fig. 5, can set up sealing ring 61 in cup joint portion 6, make sealing ring 61 and drain pipe 5 cooperation sealed, however, if only set up a sealing ring 61, when the foaming of refrigerator box, because the impact force of foaming material is great, probably break through sealing ring 61, consequently, in order to realize the complete sealing to the foaming material, as shown in fig. 5, the surface of cup joint portion 6 distributes along the axial has a plurality of sealing rings 61. The sealing rings 61 are arranged to resist the impact of the foaming material well, and the number of the sealing rings can be determined according to actual requirements, for example, as shown in the figure, five sealing rings are arranged.

Because refrigerator foaming material is filled and is foamed and be located joint portion 4 and the portion of cup jointing 6 of connecting body 1 between, and because connect body 1 be elastic material, the lateral wall surface that connects joint portion 4 and the portion of cup jointing between 6 of body 1 can receive the great pressure of foaming material, it is squashed to probably appear connecting body 1, and then the problem of blockking up water hole 2, consequently, in order to avoid this problem, as shown in the figure, lateral wall surface between joint portion 4 and the portion of cup jointing 6 has a plurality of annular strengthening ribs 7 along axial distribution. Set up a plurality of annular strengthening ribs 7, can play the effect of strengthening to the lateral wall between joint portion 4 and the portion of cup jointing 6, and then avoid connecting body 1 and squashed the problem that leads to water hole 2 to be blockked up.

It should be noted that, the side wall between the clamping portion 4 and the sleeve portion 6 of the joint body 1 may be reinforced by thickening the side wall of the joint body 1.

The joint body 1 is an elastic sealing material, and can be silica gel, rubber or an elastic plastic product, wherein the rubber material is cheap, has moderate elasticity and good sealing effect, and therefore, the joint body 1 is preferably made of rubber.
