Abstract

The utility model discloses a freezer drainage pipe assembly and a freezer. The drainage pipe assembly comprises a drainage pipe, a drainage cover and a connecting piece, wherein the connecting piece is used for connecting the drainage pipe with the drainage cover, and the connecting piece, the drainage pipe and the drainage cover are integrally formed, therefore the structure effectively avoids the phenomenon of losing the drainage cover in the process of using the freezer.

Description

Refrigerator drain assembly and refrigerator

Technical field

The utility model relates to refrigeration plant, especially a kind of refrigerator drain assembly and refrigerator.

Background technology

Generally all in household freezer, having only only a few is in refrigerating box in the draining of refrigerator.But, all adopt the mode of case internal drainage no matter be at household freezer or refrigerating box.Therefore, the drainpipe of refrigerator (outer water pipe just) all is arranged in the case, with a lid drainpipe delivery port is sealed at ordinary times, and purpose is in order to prevent that cold air scatters and disappears by drainpipe in the casing, only when defrost, Cai lid is opened, to allow water flow out.

Figure 1 shows that a kind of refrigerator drainpipe delivery port sealed structural representation in the prior art.Drainpipe 2 is installed in the refrigerator body 1, and drainpipe 2 and drain cap 3 are two independently parts, during not defrost, drain cap is inserted in the drainpipe two interference fit all.After the shortcoming of this fit system was to use overlong time, interference fit can be become flexible, and becomes matched in clearance, caused losing of drain cap easily.

Figure 2 shows that another kind of refrigerator drainpipe delivery port sealed structural representation in the prior art.In this structure, drainpipe 2 also is installed in the refrigerator body 1, and drain cap 3 also comprises integrated rubber ring 5, during use, drain cap 3 is inserted in the delivery port of drainpipe 2, and rubber ring 5 is tied up on the drainpipe 2.The shortcoming of this mode is, if after the defrost draining, forgets rubber ring is tied up on the drainpipe, also causes losing of drain cap easily.And rubber ring 5 in use, and is damaged easily, can not reach drain cap and drainpipe purpose of connecting.

To sum up, drainpipe and drain cap lack effective connection mechanism in the prior art, cause losing of drain cap easily.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of refrigerator drain assembly and refrigerator are provided, and can prevent in the refrigerator use problem of losing of drain cap.

For achieving the above object, the utility model has adopted following technical scheme: a kind of refrigerator drain assembly, comprise drainpipe, drain cap and connector, and connector connects drainpipe and drain cap, and drainpipe, drain cap and connector are formed in one.

In a kind of embodiment, the wall thickness of connector is 0.2 to 0.8 millimeter.Such as wall thickness is 0.5 millimeter.

In a kind of embodiment, drainpipe, drain cap and connector are made by the PP material.

In a kind of embodiment, drain cap is a projection, and drain cap is inserted in the drainpipe delivery port, with the drainpipe interference fit.

A kind of refrigerator comprises refrigerator body, drainpipe, drain cap and connector, and drainpipe is fixed in the refrigerator body, and connector connects drainpipe and drain cap, and drainpipe, drain cap and connector are formed in one.

Owing to adopted above technical scheme, the beneficial effect that the utility model is possessed is:

Connector connects drain cap and drainpipe, and connector, drainpipe and drain cap be the one-shot forming structure, has strengthened the switching performance of drainpipe and drain cap, in actual use, can effectively prevent the problem of losing of drain cap.

The specific embodiment

In conjunction with the accompanying drawings the utility model is described in further detail below by the specific embodiment.

Embodiment one:

Please refer to Fig. 3 to 5, a kind of refrigerator drain assembly, comprise drainpipe 2, drain cap 3 and connector 4, delivery port place at drainpipe 2, connector 4 connects as one drainpipe 2 and drain cap 3, drainpipe 2, drain cap 3 and connector 4 structure that is formed in one is such as the integrated injection molding structure.

Drain cap 3 has a projection 6, during use, drain cap 3 is inserted in the delivery port 7 of drainpipes 2, with the drainpipe interference fit with sealing drainpipe delivery port.Certainly, drain cap 3 also can be for other shape or by alternate manner and the sealing of drainpipe 2 delivery ports, such as, drain cap 3 is a matrix, drain cap 3 delivery ports have a projection, matrix and protruding fitted seal drainpipe delivery port, perhaps, mode by screw thread between drainpipe 2 and the drain cap 3 seals, certainly, also can by modes such as buckles drain cap be fixed on the drainpipe delivery port behind the drain cap 3 insertion drainpipes 2, with the bond strength of enhancing drainpipe and drain cap, thereby further prevent losing of drain cap.

The wall thickness of connector 4 is 0.2 to 0.8 millimeter, is preferably 0.5 millimeter.But this is that the result who takes all factors into consideration should not be construed concrete qualification from cost and this purpose of losing that prevents drain cap, such as, if do not consider cost, the wall thickness of connector can be made significantly thicker.The length of connector is decided according to actual conditions.

In the production, drainpipe 2, drain cap 3 and connector 4 adopt PP (polypropylene) material to make, because drainpipe 2, drain cap 3 and connector 4 adopt same material, help the buying of raw material on the one hand, saved logistics cost, on the other hand, the drainpipe 2 that material of the same race is made, drain cap 3 have identical cold and hot constriction coefficient, in use, sealing property is subjected to Effect of Environmental little.And in the prior art, such as hermetically-sealed construction shown in Figure 2, drainpipe 2 is generally used PP material, drain cap 3 rubber material, makes that both cold and hot constriction coefficients are inconsistent, thereby in use, sealing property can be had a greatly reduced quality along with the time.

The drainpipe 2 of present embodiment is fixedlyed connected by connector 4 with drain cap 3, and connector 4 and drainpipe 2 and drain cap 3 be formed in one, thereby has prevented the problem that drain cap 3 is lost in the use.

Embodiment two:

A kind of refrigerator comprises refrigerator body 1, drainpipe 2, drain cap 3 and connector 4, and drainpipe 2 fixed in position are in refrigerator body 1, and drain cap 3 is connected by connector 4 with drainpipe 2, and drainpipe 2, drain cap 3 and connector 4 are formed in one.

Above content be in conjunction with concrete embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
