Abstract

The utility model discloses a washing machine compatible with up-down drainage, and relates to the technical field of washing machines. The utility model comprises an upper drainage pump arranged at the bottom of a barrel body, wherein a water inlet of the upper drainage pump is communicated with a drainage hole arranged at the bottom of the barrel body through a main drainage pipe; the bottom shell of the upper drainage pump is provided with an opening which is communicated with a lower drainage pipe with a valve; the water outlet of the upper drainage pump is communicated with an upper drainage pipe; the valve and the upper water discharge pump are both connected with a main control panel for controlling the operation of the washing machine, and the washing machine further comprises a liquid level sensor which is connected with the main control panel and is used for detecting the water level in the barrel body. The utility model solves the problem that the water in the pipeline and the barrel body can not be completely discharged in the drainage procedure of the existing washing machine by communicating the lower drainage pipe with the bottom of the upper drainage pump.

Description

Washing machine compatible with up-down drainage

Technical Field

The utility model belongs to the technical field of washing machines, and particularly relates to a washing machine compatible with up-down drainage.

Background

With the development of the times and the progress of science and technology, the demands of people on household appliances gradually transit from functions to high quality. The washing machine is a necessary household appliance in a family and plays a very important role in the life of people.

The drainage mode of the traditional washing machine is either upper drainage or lower drainage, and the upper and lower drainage models have corresponding advantages. Go up the drainage model and can collect and reuse water, and can change the drainage position by great extent, nevertheless go up the drainage model after the drainage, because the water in the pipeline can't be discharged completely, can remain more water in the bucket, the noise is great relatively when going up the drainage model in addition when the drainage. The drainage machine type can not collect water at will for recycling, but the drainage can discharge residual water in the barrel to a greater extent, so that the dryness in the barrel is kept, and higher noise can not be brought when the drainage function works.

For example, CN98220917.7 discloses a drainage pipeline for washing machine capable of draining water up and down, which is characterized in that an outer barrel and a pump hose are arranged below a barrel body and connected with an inlet of a drainage pump, and an outlet of the drainage pump is connected with a drainage pipe. Although this system can switch between the vertical drainage, it cannot completely drain the water in the pipe line and the tank body when in use.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a washing machine compatible with upper and lower drainage, which solves the problem that water in a pipeline and a barrel cannot be completely drained in the drainage procedure of the existing washing machine by communicating an upper drainage pump and a lower drainage pipe with the bottom of the upper drainage pump.

In order to solve the technical problems, the utility model is realized by the following technical scheme:

the utility model relates to a washing machine compatible with up-down drainage, which comprises an upper drainage pump arranged at the bottom of a barrel body, wherein a water inlet of the upper drainage pump is communicated with a drainage hole arranged at the bottom of the barrel body through a main drainage pipe; an opening is formed in the bottom shell of the upper drainage pump, and the opening is communicated with a lower drainage pipe with a valve; the water outlet of the upper drainage pump is communicated with an upper drainage pipe; the valve and the upper drainage pump are both connected with a main control panel for controlling the operation of the washing machine, and the washing machine further comprises a liquid level sensor which is connected with the main control panel and is used for detecting the water level in the barrel.

Furthermore, the water outlet end of the upper drainage pipe is communicated with an L-shaped drainage section; the water outlet of the L-shaped drainage section faces downwards, and the lowest height of the water outlet of the L-shaped drainage section is higher than the top of the barrel body.

The utility model has the following beneficial effects:

the bottom of the upper drainage pump is communicated with the lower drainage pipe, and residual water in the barrel, the upper drainage pipe and the main drainage pipe is drained through the lower drainage pipe, so that the barrel is kept dry.

Of course, it is not necessary for any product in which the utility model is practiced to achieve all of the above-described advantages at the same time.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.

FIG. 1 is a schematic view of the structure of the present invention.

Detailed Description

Referring to fig. 1, the present invention is a washing machine compatible with up-down drainage, comprising an upper drainage pump 2 disposed at the bottom of a tub 1, wherein the water inlet of the upper drainage pump 2 is communicated with a drainage hole disposed at the bottom of the tub 1 through a main drainage pipe 3; the bottom shell of the upper drainage pump 2 is provided with an opening which is communicated with a lower drainage pipe 4 with a valve; the water outlet of the upper drainage pump 2 is communicated with an upper drainage pipe 5; the valve and the upper drainage pump 2 are both connected with a main control panel for controlling the operation of the washing machine, and the washing machine further comprises a liquid level sensor which is connected with the main control panel and is used for detecting the water level in the barrel body 1.

The water outlet end of the upper drainage pipe 5 is communicated with an L-shaped drainage section 51; the water outlet of the L-shaped drainage section 51 faces downwards, and the lowest height of the water outlet of the L-shaped drainage section 51 is higher than the top of the barrel body 1.

When the automatic dewatering device is used, if lower drainage is not manually set, upper drainage is firstly executed under the default condition, when the liquid level sensor detects that the drainage water level in the barrel body 1 reaches the set lowest water level, the upper drainage pump 2 is stopped to work, and the valve on the lower drainage pipe 4 is opened to carry out lower drainage until the running of a dewatering program is finished; through the switching of the upper and lower drainage, the problems of water-air mixing and unsmooth drainage are effectively prevented, and residual water in the barrel can be drained through lower drainage to keep the interior of the barrel dry.

The drain after washing may be directly set as a lower drain in which the upper drain pump 2 is in a closed state and the valve is in an open state.

If water needs to be collected, the upper drainage function can be started for collection in the rinsing process, namely, a water receiving pipe or a basin for containing water and other containers are communicated below the water outlet of the L-shaped drainage section 51.
