Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

In the related art, as shown in fig. 1, a drain pipe 1 ' is generally installed at an outer side wall of a freezing inner container 2 ' of a refrigerator such that the drain pipe 1 ' communicates with a drain hole 3 ' of the freezing inner container 2 '. Furthermore, the connection between the drain pipe 1 'and the drain hole 3' needs to be sealed with PE cotton.

The inventor researches and finds that the installation mode of the drainage pipe in the related art has at least the following problems:

firstly, in the process of installing the drain pipe 1 ' outside the freezing inner container 2 ', the drain pipe 1 ' needs to be fixed by one hand and the PE cotton needs to be installed by the other hand. The assembly action is comparatively loaded down with trivial details, and assembly efficiency is low.

Secondly, due to the characteristic of foaming and forming of the refrigerator body, when the sealing performance of the joint of the drain pipe 1 'and the freezing liner 2' is poor, foaming materials near the drain hole 3 'can overflow to block the drain hole 3'.

Thirdly, the defrosting capacity at the drain hole 3 'is weak, so that the ice blockage phenomenon is easy to occur, such as water vapor frosting or icing to block the drain hole 3'.

In view of the above-mentioned problems, the present disclosure provides a drainage structure disposed in a refrigeration device, where the refrigeration device includes a freezing liner, and the freezing liner is provided with a drainage hole. The drainage structure includes: the clamping part is integrally formed on the inner side wall of the freezing inner container and is positioned in the circumferential direction of the drain hole; the drain pipe, the first end of drain pipe is provided with overlap joint portion, overlap joint portion and joint portion sealing connection to make drain pipe and wash port intercommunication. The drainage structures in this disclosure, the drain pipe assembles on the inside wall of freezing inner bag to through the overlap joint portion of drain pipe and the direct sealing connection of joint portion of freezing inner bag, need not to set up alone sealed cotton, the assembly is more succinct, and efficiency is higher.

In an exemplary embodiment, the drainage structure of the present embodiment is provided in a refrigeration apparatus. Among these, the refrigeration device may be, for example: refrigerators, freezers, and the like. The refrigeration equipment comprises a freezing inner container, and a drain hole is formed in the freezing inner container.

As shown in fig. 2 to 5, the drainage structure 10 includes: a clamping portion 110 and a drain pipe 120. The clamping portion 110 is integrally formed on the inner sidewall 210 of the freezing inner container 20, and the clamping portion 110 is located in the circumferential direction of the drainage hole 220. The first end of the drain pipe 120 is provided with a lap joint portion 1201, and the lap joint portion 1201 is connected with the clamping portion 110 in a sealing manner so that the drain pipe 120 is communicated with the drain hole 220.

In this embodiment, the inner sidewall 210 of the freezing inner container 20 is integrally formed with the engaging portion 110 during the processing. For example, in the process of forming the freezing inner container 20 by plastic suction molding using a mold, the inner sidewall of the freezing inner container 20 is formed with the engaging portion 110 having a predetermined shape. The set shape may be, for example, a groove structure in which a step surface can be formed, a structure having a rugged surface, or the like. Since the engaging portion 110 is formed on the inner sidewall of the freezing inner container 20, the drain pipe 120 is assembled from the inside of the freezing inner container 20 when the overlapping portion 1201 of the drain pipe 120 is assembled. During the assembly process, the drain pipe 120 is firstly positioned at the inner side of the freezing inner container 20, then the pipe body of the drain pipe 120 is extended out of the drain hole 220, and the end part of the drain pipe 120 is fixed and sealed by the matching of the overlapping part 1201 and the clamping part 110, so that the drain pipe 120 is effectively limited at a proper position.

It can be understood that in the sealing and fixing scheme, the assembly action is very simple, the position is only required to be properly adjusted at the last time of assembly, two hands are not required to be matched in the assembly process, and the assembly efficiency is higher. In addition, in the scheme, PE cotton sealing is not arranged on the outer side of the freezing inner container 20, so that the assembly steps are further simplified, and the assembly efficiency is improved.

In other examples, the clamping portion 110 may be a separate structure and fixedly connected to the inner sidewall 210. For example, the end of the inner sidewall 210 near the drainage hole is provided with a load-bearing or fixing structure, such as a lap edge, and the snap-fit portion 110 is designed to be similar to the end of the inner sidewall 210. On the basis of profiling, the clamping portion 110 can be tightly attached to the end portion of the inner side wall 210, and the clamping portion 110 can be further fixed to the end portion of the inner side wall 210 in a sealing mode through adhesive. The utility model discloses do not injecing to this, as long as can make the drain pipe assemble on the inside wall of freezing inner bag.

In this embodiment, the structure of the clip portion 110 and the bridging portion 1201 can have various forms.

In the first example, the clip portion 110 is surface-contact-fitted and fixed to the bridging portion 1201. The sealing is achieved in a face contact at the same time as the overlap fixing.

That is, in the axial direction (referred to as the longitudinal direction) of the drainage hole 220, the surface where the engaging portion 110 is located is not on the same plane as the surface of the other portion of the inner sidewall 210 of the freezing inner container 20, and the surface where the engaging portion 110 is located is lower than the surface of the other portion of the inner sidewall 210.

In this example, a step concave surface as illustrated in fig. 3 may be formed at the fastening portion 110, and with reference to the radial direction of the drainage hole 220, the step concave surface is disposed to be inclined toward the drainage hole 220, that is, a predetermined angle is formed between the step concave surface and the surface where the drainage hole 220 is located, so as to facilitate water flowing out of the drainage hole 220. Freezing inner bag 20 can directly process out the joint portion 110 of step concave surface form when the plastic uptake shaping, however the utility model discloses do not do the injecing to the orientation of step, as long as can make the drain pipe assemble on freezing inner bag's inside wall.

As shown in fig. 2 and 5, the lap joint 1201 is provided with: a flange structure of the first end of the drain pipe 120.

Wherein, turn-ups structure can be perpendicular with the tip of drain pipe 120, and turn-ups structure is along keeping away from drain pipe 120 tip extensible predetermined width distance, for example: the distance of the width of the flanging structure is the same as the width of the clamping portion 110 extending on the inner side wall 210, or the distance of the width of the flanging structure is slightly smaller than the width of the clamping portion 110 extending on the inner side wall 210. The matching part of the end of the flanging structure and the end of the clamping part 110 can be selectively filled with sealing cotton or other sealing structures according to the processing requirement.

In other examples, as shown in fig. 4, a plurality of protrusions 1101 may be provided on the surface of the clip portion 110 that mates with the bridge portion 1201, and correspondingly, a plurality of grooves 12011 may be provided on the surface of the bridge portion 1201 that mates with the clip portion 110. In the assembling process of the clamping portion 110 and the overlapping portion 1201, the protrusions 1101 are in one-to-one correspondence with the grooves 12011 for clamping and sealing, so that the fixing strength of the clamping portion 110 and the overlapping portion 1201 is improved, and meanwhile, the sealing effect can be effectively achieved. Sealing materials such as PE cotton do not need to be arranged independently, and the assembly is simpler and more efficient.
