Abstract

The utility model discloses a refrigerator variable temperature greenhouse drainage structure, which is arranged on a water discharge port of a variable temperature box liner, and is characterized by comprising a water discharge pipe, wherein the water discharge pipe consists of an upper water discharge pipe and a lower water discharge pipe which are nested, sealed and connected, the upper water discharge pipe is arranged on the outer side of the nested position, the lower water discharge pipe is arranged in the inner side of the nested position, and a sealed plastic floating ball is arranged on an upper port of the lower water discharge pipe arranged in the upper water discharge pipe. The refrigerator variable temperature greenhouse drainage structure overcomes the defects in the prior art, achieves water discharge function and sealing function when a variable temperature greenhouse is in refrigerating and freezing states by designing the water discharge pipes which have different up and down diameters and are nested and sealed and the sealed plastic floating ball, and has the advantages of reliable function, tight seal and simple structure.

Description

A kind of refrigerator temperature-changing chamber discharge structure

Technical field

The utility model relates to a kind of refrigerator temperature-changing chamber discharge structure, belongs to the refrigerator body technical field of structures.

Background technology

The three open-door refrigerator is designed with the temperature-changing chamber that can switch to refrigerating chamber or refrigerating chamber according to user's request more at present, and the drainpipe bottom of most of temperature-changing chamber all is to live with rubber stopper or rubber cap seal.When selecting refrigerating chamber for use, the condensed water of refrigerator flows out from the slit of rubber stopper or rubber lid; When selecting refrigerating chamber for use, need sealing tight, prevent that cold air from leaking outside; It is tight that but this structure is difficult to sealing, and in transportation, rubber stopper or rubber lid come off easily; And also easy ageing in use causes poorly sealed and causes cold air to reveal, and increases power consumption.

Summary of the invention

The purpose of the utility model provides a kind of reliable in function, sealing refrigerator temperature-changing chamber discharge structure tight and simple in structure.

In order to achieve the above object; The technical scheme of the utility model provides a kind of refrigerator temperature-changing chamber discharge structure; Be located at the discharge outlet place of alternating temperature case courage, it is characterized in that: comprise drainpipe, drainpipe is made up of with nested being tightly connected of lower bank water pipe the top drainpipe; Nested place top drainpipe is positioned at the outside, and the lower bank water pipe is positioned at the inboard; The sealed plastic ball float is located at lower bank water pipe port in the drainpipe of top.

Preferably, said top drainpipe is the hollow cylinder body structure, open upper end, and the lower end is connected with lower bank water pipe tube wall horizontal seal.

Preferably, the said lower bank water pipe hollow cylinder body structure that is both ends open; Said lower bank water pipe diameter is less than said top drainpipe.

Preferably, the diameter of said sealed plastic ball float is between top drainpipe and the lower bank water pipe.

The utility model in use, if temperature-changing chamber is selected refrigerating chamber for use, the condensed water of refrigerator floats the sealed plastic ball float, condensed water is discharged from drainpipe; If temperature-changing chamber is selected refrigerating chamber for use, the sealed plastic ball float makes drainpipe lower end, top be in sealing state because the gravity effect is in lower bank water pipe port always, prevents the cold air leakage.

The device that the utility model provides has overcome the deficiency of prior art; Through design up and down drainpipe and the sealed plastic ball float of different, the nested sealing of diameter realized temperature-changing chamber refrigeration and drain function and sealing function when freezing, have reliable in function, the tight and characteristic of simple structure of sealing.

Sketch map when a kind of refrigerator temperature-changing chamber discharge structure that Fig. 1 provides for the utility model is assemblied on the refrigerator temperature-changing chamber;

Fig. 2 is the AA cutaway view of Fig. 1;

Fig. 3 is the partial enlarged drawing of Fig. 2.

The specific embodiment

For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.

Sketch map when a kind of refrigerator temperature-changing chamber discharge structure that Fig. 1 provides for the utility model is assemblied on the refrigerator temperature-changing chamber; Fig. 2 is the AA cutaway view of Fig. 1; Fig. 3 is the partial enlarged drawing of Fig. 2; In conjunction with Fig. 1, Fig. 2 and Fig. 3, a kind of refrigerator temperature-changing chamber discharge structure that is installed on the discharge outlet place of alternating temperature case courage 1 that the utility model provides is made up of drainpipe 2 and sealed plastic ball float 3.

Drainpipe 2 is made up of with nested being tightly connected of lower bank water pipe 2-2 top drainpipe 2-1, and lower bank water pipe 2-2 diameter is less than top drainpipe 2-1, so the nested lower bank water pipe 2-2 of place is positioned at the inboard, top drainpipe 2-1 is positioned at the outside.Lower bank water pipe 2-2 is the hollow cylinder body structure of both ends open; Top drainpipe 2-1 is the hollow cylinder body structure, open upper end, and the lower end is connected with lower bank water pipe 2-2 tube wall horizontal seal.

Sealed plastic ball float 3 diameters are between top drainpipe 2-1 and the lower bank water pipe 2-2, are located at lower bank water pipe 2-2 port in the drainpipe 2-1 of top.

A kind of refrigerator temperature-changing chamber discharge structure that the utility model provides is in when assembling, earlier sealed plastic ball float 3 from top drainpipe 2-1 port put drainpipe 2 into, install the cooperation of the discharge outlet on top drainpipe 2-1 port and the alternating temperature case courage again.In use, if temperature-changing chamber is selected refrigerating chamber for use, the condensed water of refrigerator floats sealed plastic ball float 3, and condensed water is discharged from lower bank water pipe 2-2 lower port; If temperature-changing chamber is selected refrigerating chamber for use, sealed plastic ball float 3 makes drainpipe 2-1 lower end, top be in sealing state because the gravity effect is in lower bank water pipe 2-2 port always, prevents the cold air leakage.
