The invention discloses a kind of drainer for washer, washing machine and control methods, the cleaning particle of clean bucket wall is equipped in the washing machine between outer barrel, drainage arrangement is collected cleaning particle to particle in draining and is held in chamber, and the buoyancy for Shi Shoushui of intaking floats up in washing machine between outer barrel from water inlet.Drainage arrangement includes draining valve body, inlet and outlet, water inlet is connected to washing machine outer bucket waterspout, the particle communicated with water inlet, which is equipped with, in draining valve body holds chamber, particle holds and is equipped with particle filtering structure between chamber and water outlet, which further includes the water pump mechanism that chamber water inlet is held to particle.When particle hold the indoor cleaning particle of chamber and line bits winding it is agglomerating lead to impeded drainage when, by water pump mechanism control water inlet to particle hold chamber break up line bits group smoothly to drain.Drainage arrangement of the present invention enables dispensing cleaning particle all to float, and launches more rapidly；And line bits when draining can be completely exhausted out, do not cause drainage jam.
Description
Technical field
The present invention relates to washing machine field, in particular to a kind of drainer for washer, washing machine and control method.
Background technique
It is a closed environment between the existing inside and outside bucket of washing machine, only water flow can pass through, due on washing machine
The limitation of structure and the particularity of use environment are stated, therefore after using 3-5 months, meeting on interior bucket outer wall and outer barrel inner wall
Bind dirt, so that the bacterium for breeding different degrees of bacterium, and breeding is mostly to be harmful to the human body.
With the improvement of people ' s living standards and to the raising that quality of life requires, the solution of the hygienic issues of washing machine is
It is very urgent through what is shown.Related scientific research mechanism shows that washing machine internal pollutes serious to the investigation of washing machine internal environment
Property is increasingly by the attention of consumer.In order to fundamentally avoid washing machine to the secondary dirt of washings, and more
The health of user is responsible for well, the cleaning problem of washing machine internal environment has been one, and there is an urgent need to capture.
Chinese patent 200820183308.4 disclose it is a kind of with clean drums sleeved washer between bucket, it include interior bucket,
Outer barrel and multiple round silica-gel spheres for cleaning inner and outer barrel wall, the flowing of water are driven using interior bucket rotation when laundry, thus band
Silica-gel sphere between dynamic washing machine inner tub, outer barrel moves and collides two walls of interior outer barrel constantly to reach the mesh of cleaning inner and outer barrel wall
's.
In addition, being disclosed in the Chinese patent 201010160548.4 applied before applicant a kind of using flexible particle
The washing machine and method in washing machine between outer barrel are cleaned, which, which uses, is placing flexible between outer barrel in washing machine
Grain drives flexible particle shock and friction washing machine inner and outer barrel wall by the regularity flowing of water in laundering process, realizes
Cleaning in washing machine between outer barrel.
But above-mentioned washing machine structure, after draining, since ball or flexible particle are in free scattered state in bucket,
Very big noise can be generated during high speed dewatering, while increasing the energy consumption of washing machine, influences the service life of washing machine.Therefore, it needs
The structure of existing drainage arrangement is improved, to provide a band filter structure to collect cleaning particle and line is allowed to consider to be worth doing
Cleaning particle can be launched automatically without being blocked, in washing next time for discharge, and can be freely disassembled to replace cleaning cleaning
The drainage arrangement of grain.
In addition, disclosing a kind of washing machine drainage dress in the Chinese patent 201210189764.0 applied before applicant
It sets, which includes outer barrel, interior bucket and impeller, and the cleaning particle of clean bucket wall is equipped between interior outer barrel, and outer barrel bottom is equipped with
Discharge outlet, as shown in Figure 1, the drainage arrangement holds cleaning particle, relies on buoyancy will be clear in water inlet when being included in dehydration
It washes particle emersion particle of clean bucket wall into outer barrel and holds chamber 1 ' and water drain cavity 2 ', particle holds chamber 1 ' and passes through connection
Pipe 3 ' is communicated with discharge outlet, and particle holds chamber 1 ' and floats along inner wall with cleaning particle 4 ' can be made to increase with water level and enter company
Siphunculus is entered the tilt internal wall structure of outer barrel by discharge outlet.
But by many experiments, there are still following problems for above structure: 1, cleaning particle and be integrally adhered to tilt internal wall
On, it can not be immediately by buoyancy by the upward emersion of water inlet to outer barrel in washing machine inflow, long-time upper layer cannot float
Cause all crowded below tilt internal wall；If especially particle is stored in particle long, the bottom cleaning that holds the chamber time
The grain left and right that is squeezed is fully adhered to particle and holds chamber bottom, is unfavorable for its and launches completely；2, washing machine drainage, due to cleaning
The influence of particle, line bits, which are easily collected on filter structure front, to be discharged, and long period accumulation not only will affect drainage efficiency,
Cleaning particle can also be snarled, be unfavorable for launching again.
In view of this present invention is specifically proposed.
Summary of the invention
The technical problem to be solved in the present invention is that overcoming the deficiencies of the prior art and provide a kind of simple washing machine of structure
Drainage arrangement does not cause drainage jam and secondary pollution so that line bits are completely exhausted out.
Another object of the present invention is to provide a kind of washing machines with above-mentioned drainage arrangement.
A further object of the present invention is to provide a kind of control methods of above-mentioned drainage arrangement.
In order to solve the above technical problems, the present invention is using the basic conception of technical solution:
A kind of drainer for washer, including draining valve body, inlet and outlet, draining valve body in be equipped with into
The particle that the mouth of a river communicates holds chamber, and particle, which is held, is equipped with particle filtering structure between chamber and water outlet, the drainage arrangement is also
Including holding the water pump mechanism that chamber is intake to particle.
The present invention is intake by water pump mechanism and holds the cleaning particle that chamber peening particle holds chamber to particle, its nothing is made
The movement of rule with the line bits group for being loosely blocked or winding, and re-forms new drainage gap, continues draining so that line is considered to be worth doing
It is smoothly discharged.
Further, the water pump mechanism includes a reversed water pump, the water outlet of reversed water pump and going out for drainage arrangement
Mouth of a river connection, the water inlet of reversed water pump are connected to washing machine sewer pipe.It is reverse using the water storage in drainpipe in drainage procedure
Water guide to particle is held in chamber to impact the line bits being wrapped on cleaning particle and be blocked in particle filtering structure front shadow
It rings line and considers the cleaning particle passed through to be worth doing.
Further, the reversed water pump rear portion is equipped with a draining pump drained outward, the water inlet of draining pump with
The water inlet connection of reversed water pump, the water outlet of draining pump are connected to washing machine sewer pipe.
Or the alternative of above scheme is, the water pump mechanism includes a water circulating pump, water circulating pump water inlet
Mouth is connected to outer barrel of washing machine bottom, and water outlet and particle hold chamber.
Again or alternative is, the water pump mechanism includes a two-way draining pump, and the double drainage pump includes one
