Description
Technical field
The present invention relates to the washing machine technical field, relate in particular to a kind of drainage system that reduces the washing machine drainage noise, and utilize this system to reduce the control method of drainage noise.
Background technology
Washing machine can produce very large noise in dehydration, wherein a part of reason is to cause noise to increase because half-dried suction can appear in draining pump in drainage procedure, and this noise brings inconvenience to the user.As shown in Figure 1, existing washing machine drainage system comprises draining pump 04, and draining pump 04 is provided with the draining pump water inlet pipe 04 that joins with the washing machine urceolus, and draining pump outlet pipe 02, and in drainage procedure in the past, draining pump 04 often leaves.Its drainage principle is: after drainage procedure is opened; Draining pump 04 can be merely by the programme-control opening and closing; When draining pump 04 was opened, the water in the urceolus entered in the draining pump 04 along draining pump water inlet pipe 01, and draining pump impeller 03 is at this moment opened; Through the rotation of draining pump impeller 03, the water in the draining pump 04 05 is passed through to discharge in the draining pump outlet pipe 02.Along with the water in the urceolus reduces; Water 05 in the draining pump 04 also can be fewer and feweri; State as shown in Figure 2 will occur, only some water 05 is in draining pump 04, and draining pump outlet pipe 02 can suck portion of air when sucking water 05; Cause draining pump 04 to produce bigger noise, thereby influence the performance of whole washing machine aspect noise.
In order to address this problem; Existing washing machine structurally improves, but DeGrain, and for example Chinese patent document CN 1304469A discloses a kind of " reducing the washing machine of draining pump noise "; Its improved structure is between draining pump and scupper hose, to dispose by-pass hose; When the water surface in the cylindrical shell reduced, it can make remaining low amounts of water circulation in the tube, reduced the noise of the draining pump of washing machine like this.But this structure is because water is to recycle, and noise reduction is not obvious, and the energy consumption of whole drainage procedure is increased, and is unfavorable for energy-saving and emission-reduction.
For example Chinese patent document CN 201507484U discloses a kind of " the low noise pump case of drainage pump of washing machine " again; It mainly is on the basis that comprises the pump case that pump chamber, filter chamber and delivery port are formed; On near the pump chamber at delivery port place and the pump case inwall end face between the filter chamber, have additional an explosionproof hole; Be in " half water, half gas " during the stage when draining pump then, after remaining water and air mixes in the pump chamber, under the effect of wheel rotation; Understand some residual water through the explosionproof hole on the pump case inwall " backflow " in the filter chamber; Discharge the periodic pressure outburst that remaining water and air is produced after mixing in the pump chamber, and then reduce the noise of drainage pump of washing machine in draining, this structure is not clearly to the effect that reduces the draining pump noise.
Summary of the invention
The objective of the invention is to address the above problem; A kind of drainage system and control method thereof that reduces the washing machine drainage noise is provided; It has simple in structure, noise is little, drainage efficiency is high, advantage of low energy consumption; And it can accomplish the decomposition of noise, the noise in the simple and effective reduction dehydration under the prerequisite that does not influence the laundry machine dehydration drying.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of drainage system that reduces the washing machine drainage noise; Comprise draining pump with and the draining pump water inlet pipe and the draining pump outlet pipe that go up to be provided with; Between said draining pump water inlet pipe and washing machine urceolus, be provided for detecting the condensate tank of dehumidifier of water level in the draining pump; Said condensate tank of dehumidifier is transferred to controller outside with water level signal, and the real-time start and stop of said controller control draining pump are to guarantee in the laundry machine dehydration process, remaining full water state in the draining pump.
Further, be provided for the fixedly water tank of water storage between said draining pump and the washing machine urceolus, said fixedly water tank is connected with the washing machine urceolus through the urceolus drainpipe, and said condensate tank of dehumidifier is arranged in the said fixedly water tank.
Preferably, said condensate tank of dehumidifier is a switch.
Preferably, said condensate tank of dehumidifier is a sensor.
Further, said switch comprises the float that is arranged in the said fixedly water tank, the switch button that the setting of said fixedly water tank inner tip is connected with controller outside, and the density of said float is less than the density of water.
Further, also corresponding said sensor is provided with water level stake in the said fixedly water tank, and the position of said water level stake and said draining pump full water water level are consistent.
Preferably, the lowest surfaces of the inner chamber of said fixedly water tank is higher than said draining pump water inlet pipe inwall lowest surfaces, and the highest face of the inner chamber of said fixedly water tank is lower than the highest of the inwall of said draining pump.
A kind of control method that reduces the drainage system of washing machine drainage noise comprised with the next stage:
The a stage: washing finishes in the drainage procedure, and after washing machine got into dehydration procedure, condensate tank of dehumidifier was given signal of often opening of controller, and controller control draining pump carries out drainage works;
The b stage: in the dehydration, condensate tank of dehumidifier detects water level, when water level is lower than requiring of condensate tank of dehumidifier; Condensate tank of dehumidifier is passed to controller with shutdown signal, and controller control draining pump stops drainage works, when water level rises to requiring of condensate tank of dehumidifier; Condensate tank of dehumidifier is passed to controller with start signal; Controller control draining pump carries out drainage works, and so circulation finishes until washing machine dehydration procedure.
Further, also comprise the c stage: after washing machine dehydration procedure finished, controller was controlled draining pump separately and is opened 15s, so that the remaining moisture of emptying.
Beneficial effect of the present invention is: through between washing machine urceolus and draining pump water inlet pipe, condensate tank of dehumidifier being set; This condensate tank of dehumidifier can be transferred to controller outside with the signal of water level; The start and stop of controller control draining pump, thus realize according to height of water level ON/OFF draining pump, avoid the stack of half-dried suction noise of vibrating noise and the draining pump of washing machine when high speed dewatering; Noise is disperseed, reach the purpose that reduces the washing machine noise; Through between washing machine urceolus and draining pump water inlet pipe, fixedly water tank being set; And condensate tank of dehumidifier set within it; Fixedly be connected through soft urceolus drainpipe between water tank and the washing machine urceolus simultaneously, like this can be for condensate tank of dehumidifier provides a stable liquid level, to guarantee that draining pump starts accurately as requested and stops; The contrast prior art, that this drainage system has is simple in structure, noise is little, drainage efficiency is high, advantage of low energy consumption.
