Embodiment

In the utility model, in the case where not making conversely explanation, the noun of locality such as " upper and lower, top, bottom " used is usually It is each component mutual alignment either on vertical, vertical or gravity direction for direction shown in the drawings Relationship description word.

The utility model provides a kind of washing machine, wherein, the washing machine includes interior bucket 10, outer barrel 20 and driving machine Structure, the bottom through the interior bucket 10 and outer barrel 20 that the driving mechanism includes clutch 30 and is connected with the clutch 30 The wash shaft 40 that portion is set, the washing machine further include the first row Aquaporin-5 0 for the clutch 30, for described outer The sealing device 70 of second drainage channel 60 of bucket 20 and the mounting hole for wearing the wash shaft 40 of the sealing interior bucket 10, The sealing device 70 includes the sealing cover 71 with the wash shaft 40 sealing assembling, define in the sealing cover 71 with it is described The cavity 72 that outer barrel 20 is isolated and connected with the first row Aquaporin-5 0, the top of the sealing cover 71 are provided with and the chamber The osculum 711 that body 72 connects, 0 and second drainage channel 60 of first row Aquaporin-5, which can converge and form total draining, to be led to Road 80, is provided with drain valve 51 on the first row Aquaporin-5 0, the flow area of the osculum 711 is more than the second row The cross-sectional area of aquaporin 60.

Using the washing machine of the utility model, interior bucket 10 has no in bottom with outer barrel 20 and directly connects, and is only capable of by first Drainage channel 50 is connected with the second drainage channel 60, by controlling the operation of drain valve 51, can only be made in washing process interior There is water in bucket 10, so as to fulfill water-saving result.Further, since substantially avoid directly connection interior bucket 10 and outer barrel 20, reduce Therebetween time for connecting, thus secondary pollution caused by long-time water coke slurry therebetween can be reduced.By making The flow area for stating osculum 711 is more than the cross-sectional area of second drainage channel 60, it can be ensured that draining is smooth.

Wherein, in the case where osculum 711 is multiple, the flow area of above-mentioned osculum 711 refers to multiple osculums 711 Total flow area.For ease of smooth draining, drainage channel 60 can be the pipeline that internal diameter is R, then the osculum 711 is logical Flow area is more than π R²。

Sealing cover 71 can be installed by appropriate ways, assembled as long as can be sealed with wash shaft 40 and limited cavity 72 i.e. Can.For ease of installing and obtaining firm installation foundation, it is preferable that the sealing cover 71 and the bottom plate 11 of the interior bucket 10 are fixed and connected Connect.For example, as shown in figure 3, sealing cover 71 can be fixed on the top of bottom plate 11 by bolt P.

In addition, to ensure the sealed connection of close cavity 72 and first row Aquaporin-5 0, can by appropriate seal come It is tightly connected sealing cover 71 and first row Aquaporin-5 0.For example, as shown in figure 4, the first row Aquaporin-5 0 can include stretching Go out the port of the bottom plate 11, the sealing device 70 includes cricoid seal 73, and the sealing cover 71 passes through the sealing Part 73 is connected with the port sealing.Since sealing cover 71 is fixed with bottom plate 11, it is necessary to be rotated during dehydration etc., and the One drainage channel, 50 remains stationary, therefore, the sealing cover 71 are configured to hermetically rotate relative to the seal 73. Wherein, seal 73 can be various appropriate lip rings, such as oil sealing.

To realize the cleaning processes such as the washing of washing machine and dehydration, the washing machine includes coaxially setting with the wash shaft 40 Put and be connected to the dehydrating shaft 90 of the clutch 30, the dehydrating shaft 90 is fixedly connected with the bottom plate 11.For ease of setting Sealing device 70 and do not interfere wash shaft 40 and the relative arrangement of dehydrating shaft 90, the sealing cover 71 is arranged on the wash shaft 40 With the junction of dehydrating shaft 90.

In addition, to ensure that interior bucket 10 is connected with outer barrel 20 in bottom without other, the bottom of the interior bucket 10 is only in the peace Dress has perforate at hole.For ease of dehydration, the side wall of the interior bucket 10 has the through hole connected with said tub 20, dehydration In, interior bucket 10 is rotated by dehydrating shaft 90 and throws away the water in interior bucket 10 from through hole.

In the utility model, for ease of rapid, uniform draining, as shown in figure 3, the osculum 711 is multiple, Duo Gesuo Stating osculum 711 can be set around the wash shaft 40.

Preferably, it is to be operated according to needs, water level sensor 52 is provided with the first row Aquaporin-5 0, it is described Washing machine includes the control device being electrically connected with the water level sensor 52, and the control device is used to control the drain valve 51 Operation.Wherein, water level sensor 52 can be various appropriate formats, such as the pressure in feedback first row Aquaporin-5 0, from And control device can judge the water level in interior bucket 10 according to the feedback of water level sensor 52 and carry out corresponding operating.Wherein, water Level sensor 52 can be set in position, as long as the pressure in first row Aquaporin-5 0 can be fed back to aid in control to fill Put the water level judged in interior bucket 10.For example, the water level sensor 52 can be arranged on the upstream of the drain valve 51, from And the relatively low water level sensor 52 of detection pressure threshold can be selected.

Wherein, control device can set various programs, to carry out corresponding operating.As shown in Fig. 2, for after the completion of cleaning Draining is carried out, the control device is arranged to control the drain valve 51 to open in drainage procedure, will pass through first row water Passage 50 and total drainage channel 80 discharge the water in interior bucket 10.And in washing process, as shown in Figure 1, the control device It is arranged to control the drain valve 51 to close in washing process.

In addition, the control device can also control the water inlet system of the washing machine and the operation of the driving mechanism, To coordinate drain valve 51 to carry out corresponding cleaning operation.

Illustrate the operation of the washing machine of the utility model referring to Fig. 1 and Fig. 2.

As shown in Figure 1, washing machine is in washing process, at this time, control device control drain valve 51 closes and controls water inlet System is intake to interior bucket 10 so that only has water in interior bucket 10.When the signal that control device is fed back according to water level sensor 52 judges When water level in interior bucket 10 reaches predetermined value, control device control water inlet system stops intaking and controls driving mechanism driving to wash Axis 40 is washed, wash shaft 40 drives impeller S, so as to start to wash.

In dehydration, control device control driving mechanism driving dehydrating shaft 90, interior bucket 10 starts to rotate, in interior bucket 10 Water can be got rid of into outer barrel 20 by the through hole on side wall.

As shown in Fig. 2, in the drainage procedure after cleaning, control device control drain valve 51 is opened, in interior bucket 10 Water discharged through first row Aquaporin-5 0 and total drainage channel 80.Water during dehydration into outer barrel 20 can also lead to through the second draining Road 60 and total drainage channel 80 are discharged.

The preferred embodiment of the utility model, still, the utility model and unlimited are described in detail above in association with attached drawing In this.In the range of the technology design of the utility model, a variety of simple variants can be carried out to the technical solution of the utility model. The utility model is combined in any suitable manner including each particular technique feature.In order to avoid unnecessary repetition, The utility model no longer separately illustrates various combinations of possible ways.But these simple variants and combination should equally be considered as this Utility model disclosure of that, belongs to the scope of protection of the utility model.
