Be filled with air in certain amount in the described air vessel 18, the air that is filled in the air vessel 18 bears different pressure according to the height of washings water level, the pressure that air bore in the air vessel 18 passes to level sensor 20 by tube connector 19, level sensor 20 reflects the height of washings water level according to the size of pressure signal.
As shown in Figure 2, the discharge structure of above-mentioned washing machine is: the bottom of outer bucket 11 is formed with osculum 11, the lower end of osculum 11 is provided with and scupper hose 16, be provided with draining valve 17 in the scupper hose 16, washings can be discharged in the scupper hose 16 under the control of draining valve 17, described draining valve 17 is connected with drain motor 22 by pivot link 21; In addition, also be provided with the draining pump 23 of forcing to discharge the washings in the scupper hose 16 on the drainpipe.Certainly, be provided with seal member 24 between osculum 11 on the outer bucket 11 and the scupper hose 16, to prevent the leakage of washings.
The course of work to above-mentioned existing washing machine is illustrated below: at first outwards put into laundry item and inject washings in the bucket 11, drop into washing agent, connecting power supply then starts drive unit 15, bucket 12 and impeller began rotation in drive unit 15 drove, the rotation of impeller drives washings and produces rotary water current, make and rub between washings and the clothing, thereby reach the purpose of washing clothes.
After washing procedure finishes, carry out drainage procedure, the washings in the outer bucket 11 are emitted.In drainage procedure, at first drain motor 22 is activated, by pivot link 21 first elastomeric elements 17 with draining valve 17 ' retreat second elastomeric element 17 " to be compressed, draining valve 17 is opened; Meanwhile, draining pump 23 begins to start, and the washings scupper hose 16 under the effect of draining pump 23 in outer barrel 11 discharges.
The draining of washings is over, and drain motor 22 and draining pump 23 quit work, and draining valve 17 is at second elastomeric element 17 " the effect of restoring force under be turned off.
The shortcoming of above-mentioned existing washing machine is: the discharge structure of washing machine and level measurement device are independently separately to constitute, and therefore, have complex structure, building block is many, manufacturing cost is high shortcoming.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of above-mentioned existing washing machine, provide a kind of simple in structure, building block is few, low cost of manufacture and the scupper hose syndeton into a single integrated structure washing machine of level measurement device.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the scupper hose syndeton of washing machine of the present invention comprises: the bottom that is arranged on outer bucket is used for discharging the scupper hose of outer bucket washed water, the outer lower portion that is arranged on outer bucket and the inner air vessel that is filled with a certain amount of air; Described scupper hose is connected with the delivery outlet of draining pump, and the input port of draining pump is connected with the lower end of air vessel by tube connector; The upper end of described air vessel is connected with level sensor by tube connector.
Described level sensor perceives the pressure that passes over by tube connector and is reduced to certain value when following, and draining pump is out of service.
The invention has the beneficial effects as follows: the scupper hose syndeton and the level measurement device of washing machine is into a single integrated structure, simple in structure, building block is few, low cost of manufacture.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
As shown in Figure 3, adopt the washing machine of scupper hose syndeton of the washing machine of present embodiment to comprise: housing 50, be arranged on outer bucket 51 in the housing 50, be arranged in the outer bucket 51 and be connected with drive unit 53 rotatable in bucket 52 and scupper hose syndeton.
Described scupper hose syndeton comprises: be arranged on the scupper hose 55 of outer bucket 51 bottoms, be connected with the bottom of outer bucket 51 and inside is filled with the air vessel 54 of a certain amount of air, by the tube connector 57 and the upper end of air vessel 54 tube connector 59 that the level sensor 56 that can come perception washings water level by the air pressure of air vessel 54 inside and two ends are connected with draining pump 58 with the lower end of air vessel 54 respectively that is connected.
The advantage of the scupper hose syndeton of the washing machine of present embodiment is: the scupper hose syndeton and the level measurement device of washing machine is into a single integrated structure, simple in structure, building block is few, low cost of manufacture; Draining valve need not be set in addition, just can finish the discharging of washings and the water level of perception washings.
The course of work to the washing machine of the scupper hose syndeton of the washing machine that adopts present embodiment is illustrated below: at first outwards put into laundry item and inject washings in the bucket 51, drop into washing agent, connecting power supply then starts drive unit 53, bucket 52 and impeller began rotation in drive unit 53 drove, the rotation of impeller drives washings and produces rotary water current, make and rub between washings and the clothing, thereby reach the purpose of washing clothes.
After washing procedure finishes, carry out drainage procedure, draining pump 58 begins to start, and the washings that flow in the air vessel 54 are supplied on the draining pump 58 by tube connector 59, under the driving of draining pump 58, washings are by the outside of scupper hose 55 rows to washing machine then; Meanwhile, the air pressure of air vessel 54 passes to level sensor 56 by tube connector 57, and level sensor 56 can perceive the height of washings water level according to the size of the pressure that passes over.Carrying out along with drainage procedure, the water level of the washings in the outer bucket 51 reduces gradually, air pressure in the air vessel 54 also decreases, when the air pressure in the air vessel 54 is reduced to certain value when following, washings outside level sensor 56 is judged in the bucket 51 have discharged and have finished, and draining pump 58 is out of service immediately.Like this, draining pump 58 still continues operation can to prevent outer bucket 51 interior washings dischargings to finish afterwards, and the phenomenon that causes draining pump 58 to break down also makes air vessel 54 inside that the maintenance air in certain amount is set simultaneously.
