Abstract
The invention discloses a refrigerator water discharging pipe which comprises a lengthwise pipeline and a rubber stopper sleeved at one end of the pipeline. A door-opening power assisting structure is connected at the other end, where the rubber stopper is positioned, of the water discharging pipe, and when a refrigerator door is closed, the lower end of the door-opening power assisting structure is only communicated with the pipeline; when the refrigerator door is opened, pressure in a refrigerator body is smaller than atmospheric pressure, atmosphere leads air into an outer frame through an opening of the outer frame and enables a floater to float, the door-opening power assisting structure is communicated with the pipeline and the atmosphere through the floater, and outside air is quickly added into the refrigerator body to enable pressure inside the refrigerator body and pressure outside the refrigerator body to be quickly balanced and to enable door opening force to be reduced.
Description
Technical field
The present invention relates to household electrical appliance technical field, particularly relate to a kind of refrigerator drainpipe that is provided with the boosting mechanism that opens the door.
Background technology
Because the casing of refrigerator is a structure for sealing relatively, in the moment of opening the door, because door seal moment produces compared with large deformation, make the urgent sharp increase of volume of air wink in casing large, make to form negative pressure in refrigerator, make that refrigerator doors is more difficult to be opened, especially for clamshell doors large refrigerator refrigerating chamber.Therefore, user, pursue in household electrical appliances experience more laborsaving, that save worry, the research on refrigerator open boosting mechanism is a long-term research topic.Although being refrigerator, refrigerator drainpipe closes inner unique passage directly communicating with atmosphere behind the door, as shown in Figure 1, but by drainpipe, enter continuously refrigerator for fear of extraneous hot-air, increase energy consumption of refrigerator, it can guarantee simple drain function, and it is very little that the osculum of rubber stopper designs as far as possible.Therefore, when opening the door, can not supplement rapidly new air and enter casing, be opened the door in process always in negative pressure in casing inherence, the power of opening the door is tight.
Therefore,, for the problems referred to above, be necessary to provide a kind of new refrigerator drainpipe.
Summary of the invention
In view of this, the present invention, by a kind of refrigerator open boosting mechanism is provided, solves the large problem of power of opening the door effectively.To achieve these goals, technical scheme provided by the invention is as follows:

As a further improvement on the present invention, the described boosting mechanism that opens the door comprises the tubulose housing of a hollow, on described housing, be provided with some openings, in described housing, be provided with the float that can fluctuate, described float middle part is a through hole, when refrigerator doors is closed, described in the boosting mechanism lower end of opening the door only by through hole and the described pipeline of float, be connected; When refrigerator open, atmosphere is incorporated into air in described housing by the opening of described housing, and float upwards floats, and the through hole of the boosting mechanism that opens the door by float is connected with described pipeline and atmosphere simultaneously.
As a further improvement on the present invention, described housing comprises the first framework and the second framework, and the internal diameter of described the first framework is greater than the internal diameter of the second framework, and the some openings on described housing are arranged in the first framework.
As a further improvement on the present invention, described float comprises roof, diapire and the sidewall that connects roof and diapire, between described sidewall and the inwall of housing, is provided with space.
As a further improvement on the present invention, the roof of described float and the angle between sidewall are acute angle.
As a further improvement on the present invention, on the perisporium of described the second framework, be also provided with the protuberance moving down for limiting float.
As a further improvement on the present invention, described drainpipe also comprises the blocking cap that is provided with through hole, and described blocking cap is set in and opens the door on boosting mechanism.
As a further improvement on the present invention, described blocking cap is fixedly connected with by buckle and draw-in groove fit structure with the described boosting mechanism that opens the door.
By above technical scheme, can be seen, the present invention is provided with by the refrigerator drainpipe providing the boosting mechanism that opens the door, and is opening the door moment, by being arranged on the float in drainpipe, make atmosphere supplement rapidly inlet body, make refrigerator external and internal pressure reach rapidly balance, improve the tight problem of refrigerator open power;
At closing time, because the pressure in refrigerator increases rapidly, form malleation in refrigerator, float falls very soon, forms well sealing, avoids extraneous hot-air to enter refrigerator, increases energy consumption of refrigerator, reaches certain energy-conservation effect simultaneously simultaneously.
