The washing machines on the market generally have to wash when washing underwear and need manually put into the detergent each time, and troublesome and loaded down with trivial details, and can't accurately confirm the problem of putting into detergent amount each time.
The application aims to provide an automatic detergent feeding device and a washing machine with the same, and the problem is solved.
[ example 1 ]
The embodiment provides a washing machine, which comprises an automatic detergent feeding device, wherein the automatic detergent feeding device comprises a shell 1, the shell 1 forms a cylindrical cavity, when the washing machine runs, as a water channel in the washing machine is filled with water flow, the water flow in the cavity flows into the cylindrical cavity along the direction A, and the flowing water flow pushes a piston 2 to extrude an elastic connecting piece 3. The detergent liquid inlet D is provided with a first one-way valve 11, the first one-way valve 11 is communicated with the detergent containing box 4 and only allows the detergent to flow towards the direction D of the detergent liquid inlet, and the detergent liquid outlet is provided with a second one-way valve.
The second one-way valve 12 communicates with the washing chamber and only allows the detergent to flow towards the washing chamber, which detergent flows towards the washing chamber through direction B. A piston 2 capable of moving along the length direction of the columnar cavity is arranged in the columnar cavity, the piston 2 divides the columnar cavity into two parts, wherein the first part of the cavity contains water, the second part of the cavity contains detergent, a water inlet is arranged at the first part of the cavity, a detergent liquid inlet and a detergent liquid outlet are arranged at the second part of the cavity, an elastic connecting piece 3 is arranged between the piston 2 at the second part of the cavity and a second one-way valve, when the elastic connecting piece 3 is compressed, the first one-way valve 11 is closed, and the second one-way valve 12 is opened; when the elastic connecting piece recovers deformation, the first one-way valve is opened, and the second one-way valve is closed.
Preferably, the elastic connector is a spring or an elastomer.
Preferably, the elastic connecting member is integrally formed with the piston when being an elastic body.
Preferably, the first check valve 11 and the second check valve 12 include a valve housing, a valve body, and a spring, wherein the valve body and the spring are fixed within the valve housing.
In the embodiment, when the automatic detergent feeding device works, the piston 2 is moved by using the water pressure change of the first part cavity, and the position of the piston and the volume of the detergent cavity correspond to the water amount required by a washing program set by a user. The water pressure of the first part cavity is determined by the water quantity required by the washing program set by a user; the method specifically comprises the following steps: the maximum value of the elastic force of the spring 113 is less than the water pressure in the tap water pipe, and the minimum value is greater than the water pressure when tap water is not connected and the water pump does not work; therefore, when water is fed or operated, the pressure in the water pipe pushes the piston to extrude the spring, when tap water is not connected and the water pump does not work, the spring can recover, and the detergent can be put in for many times by using the water connection and disconnection for many times so as to achieve the required detergent amount.
When the washing machine works, the amount of the detergent thrown in once reciprocating motion of the piston 2 is equal to the amount of the detergent thrown in needed for one-time washing.
In each reciprocation of the piston 2, the detergent chamber has the largest volume when the piston 2 is positioned at the leftmost side of the chamber, and the water chamber has the largest volume when the piston 2 is positioned at the rightmost side of the chamber.
The working process of the automatic detergent feeding device is as follows: when the washing machine is in operation, because the water channel in the washing machine is filled with water flow, the water flow on the cavity flows into the cylindrical cavity along the direction A, and the inflowing water flow pushes the piston 2 to extrude the elastic connecting piece 3. The elastic connecting piece 13 opens the detergent outflow channel by extruding the piston arranged in the second one-way valve 12, so that the detergent enters the washing chamber along the direction B, the piston in the first one-way valve 11 is pressed back to block the detergent liquid inlet, and the putting is finished at the moment.
When the washing machine is operated in a dewatering mode, because the water pressure is reduced, the elastic connecting piece 3 recovers, the piston 2 is pushed, water in the cylindrical cavity is pushed out of the putting device from the direction C, negative pressure is formed in the cylindrical cavity of the putting device at the moment, under the action of the negative pressure, the piston in the second one-way valve 12 is subjected to pressure generated by the negative pressure to block the detergent putting channel, the valve body 111 on the first one-way valve, namely the piston arranged on the first one-way valve, moves downwards under the action of pulling force generated by the negative pressure and drives the piston to compress downwards at the same time, the channel is opened, so that detergent is sucked into the putting device from the detergent containing box 4 in the direction D, and automatic detergent filling of the putting device is completed.
As shown in fig. 2, the washing machine in this embodiment includes a plurality of washing cavities, each washing cavity is correspondingly provided with a corresponding automatic detergent feeding device, and each automatic detergent feeding device is communicated with a water inlet of the corresponding washing cavity.
Preferably, the washing machine of the present embodiment is provided with a first washing chamber 5, and the first washing chamber is provided with a first washing automatic putting device 51; the washing machine of the present embodiment is further provided with a second washing chamber 6, and a second washing automatic putting device 61 is arranged on the second washing chamber.
Further, an elastic rubber balloon may be used instead of the spring and piston functions of the present embodiment.
According to the washing machine provided by the embodiment, on one hand, the automatic detergent feeding device achieves the effects of automatic feeding and automatic filling of detergent by utilizing the interaction of water pressure and a spring; on the other hand, the problem that the washing machine cannot accurately determine the amount of the detergent put in each time is solved by using the fact that the amount of the detergent put in once after the piston reciprocates and is required by once washing.
In summary, the present invention provides an automatic detergent dispensing device, which comprises a housing, wherein the housing forms a cylindrical cavity, a water inlet 13, a detergent inlet and a detergent outlet are formed on the cavity, wherein the water inlet 13 is communicated with a water inlet pipe, the detergent inlet is provided with a first one-way valve, the first one-way valve is communicated with a detergent containing box and only allows the detergent to flow towards the detergent inlet, the detergent outlet is provided with a second one-way valve, the second one-way valve is communicated with a washing chamber and only allows the detergent to flow towards the washing chamber, a piston capable of moving along the length direction of the cylinder is arranged in the cylindrical cavity, the piston divides the cylindrical cavity into two parts, the water inlet is arranged in the first part of the cavity, the detergent inlet and the detergent outlet are arranged in the second part of the cavity, and an elastic connecting member is arranged between the piston in the second part of the cavity and the second one, the elastic connecting piece is compressed, the first one-way valve is closed, the second one-way valve is opened, the elastic connecting piece recovers deformation, the first one-way valve is opened, and the second one-way valve is closed; the washing machine with the device solves the problems that when underwear is washed, detergent needs to be put in manually, the washing machine is troublesome and tedious, and the detergent amount put in each time cannot be determined accurately.
