The laundry washing machine, as shown in fig. 1, comprises a first washing chamber 12, a second washing chamber 8, a first dosing device 11 and a second dosing device 10. The first dosing means 11 are used for the automatic dosing of the first washing chamber 12 and the second dosing means 10 are used for the automatic dosing of the second washing chamber 8. The first washing chamber 12 comprises a first water inlet pipeline 1, the first water inlet pipeline 1 is branched into a first branch pipeline 2, the first branch pipeline 2 is connected with a first water inlet 13 of the first feeding device 11, and a first liquid outlet 14 of the first feeding device 11 is communicated with the first washing chamber 12.

The first water inlet pipeline 1 and the second water inlet pipeline 3 are respectively communicated with a main water inlet pipeline of the washing machine and used for accessing municipal water. The first branch pipeline 2 is provided with a first control valve 4 for controlling the on-off of the first branch pipeline 2, and the second branch pipeline 6 is provided with a second control valve 5 for controlling the on-off of the second branch pipeline 6.
The detergent dispensing device further comprises a detergent containing box 9, wherein the first detergent containing box 9 is respectively communicated with the first dispensing device 11 and the second dispensing device 10 and is used for supplying detergent to the first dispensing device 11 and the second dispensing device 10. A separate first liquid inlet is arranged on the first feeding device 11 and a separate second liquid inlet is arranged on the second feeding device 10. The first detergent containing box 9 is communicated with the first feeding device 11 through a first liquid inlet and is communicated with the second feeding device 10 through a second liquid inlet.
The waterway principle is as follows: in the washing water inlet process, water flows into a first washing cavity 12 and a second washing cavity 8 from a first water inlet pipeline 1 and a second water inlet pipeline 3, part of water enters a first throwing device 11 and a second throwing device 10 through a first branch pipeline 2 and a second branch pipeline 6 respectively, the water flows entering the first throwing device 11 and the second throwing device 10 are gradually accumulated to form pressure to push piston extrusion springs inside the first throwing device 11 and the second throwing device 10, and a detergent in the throwing devices is squeezed into the washing cavities from a first liquid outlet 14 and a second liquid outlet 7. In this embodiment, the control valve controls the branch pipe to maintain the passage during the washing process performed by the washing chamber and to maintain the disconnection during the rinsing process, wherein the washing process includes a washing water inlet process and a washing dehydration process. Before the washing water enters, the rated input amount of the detergent is calculated according to the load in the washing chamber, and the moving distance of the piston relative to the cylindrical cavity is controlled according to the rated input amount, so that the detergent can be accurately input. In the washing and dewatering process, the water flow in the branch pipeline reduces the water pressure and reduces, the spring force in the throwing device is larger than the water pressure thrust force to push the piston to form negative pressure in the cavity to suck the detergent and finish automatic filling, and preparation is made for the next automatic throwing. In the rinsing process, the auxiliary washing by the detergent is not needed any more, so that the shutoff valve of the branch pipeline is closed, no water flows through the branch pipeline, and the liquid is not thrown by the throwing device.
As shown in fig. 3, the dispensing device of this embodiment includes a housing 100, the housing 100 forms a cylindrical cavity, a water inlet and a liquid outlet are respectively located at two ends of the cylindrical cavity, a liquid inlet is located on a side wall of the cylindrical cavity, a first check valve 400 is disposed on the liquid inlet, and a second check valve 500 is disposed on the liquid outlet;
a piston 200 capable of moving along the length direction of the columnar cavity is arranged in the columnar cavity, the columnar cavity is divided into a first cavity and a second cavity by the piston 200, the first cavity contains water, the second cavity contains detergent, a water inlet is communicated with the first cavity, a liquid inlet and a liquid outlet are communicated with the second cavity, an elastic connecting piece 300 is arranged between the piston 200 and a second one-way valve 500, and when the elastic connecting piece 300 is compressed, the first one-way valve 400 is closed, and the second one-way valve 500 is opened; when the elastic connection member 300 is restored to be deformed, the first check valve 400 is opened and the second check valve 500 is closed. Preferably, the elastic connection 300 is a spring 413 or an elastomer. The elastic connection member 300 is integrally formed with the piston 200 when it is an elastic body.
Further, the first check valve 400 and the second check valve 500 include a valve housing 412, a valve body 411, and a spring 413, wherein the valve body 411 and the spring 413 are fixed within the valve housing 412.
In the embodiment, when the automatic detergent dispensing device works, the piston 200 is moved by using the water pressure change of the first partial cavity, and the position of the piston 200 and the volume of the detergent cavity correspond to the amount of water required by a washing program set by a user. The water pressure of the first part cavity is determined by the water amount required by the washing program set by the user.
The amount of detergent put in one time of reciprocating the piston 200 when the washing machine is in operation is the amount of detergent required for one time of washing.
In each reciprocation of the piston 200, the detergent chamber has the largest volume when the piston 200 is positioned at the leftmost side of the chamber, and the water chamber has the largest volume when the piston 200 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 flowing water flow pushes the piston 200 to extrude the elastic connecting piece 300. The elastic connector 300 opens the detergent outflow passage by pressing the piston 200 arranged in the second check valve 500, so that the detergent enters the washing chamber along the direction B, the piston 200 in the first check valve 400 is pressed back to block the detergent inlet, and the putting is finished at this moment.
When the washing machine is operated in a dewatering mode, because the water pressure is reduced, the elastic connecting piece 300 recovers, the piston 200 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 200 in the second one-way valve 500 is subjected to pressure generated by the negative pressure to block a detergent putting channel, the valve body 411 on the first one-way valve 400, namely the piston 200 arranged on the first one-way valve 400, moves downwards under the action of pulling force generated by the negative pressure and drives the detergent putting channel 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 in the direction D, and automatic detergent filling of the putting device is completed.
The water path control of the present invention is explained as follows:
before automatic putting is performed, which washing chamber needs to be judged to perform washing, when only one washing chamber is judged to perform washing, for example, the first washing chamber 12 is used for washing, the first control valve 4 is opened, then water enters the washing machine, water flows in from the first branch pipeline 2, water flow entering the first putting device 11 is gradually accumulated to form pressure to push the piston extrusion spring, meanwhile, detergent is extruded into the first washing chamber 12 from the first liquid outlet 14 of the first putting device 11, the washing putting process is finished, and the washing machine starts washing.
When the washing machine starts to dewater after washing is finished, the first control valve 4 keeps a passage at the moment, and water flow in the first branch pipeline 2 is discharged along with water flow in the water inlet pipeline of the washing machine. The water flow in the first branch pipeline 2 reduces the water pressure, the spring force in the first feeding device 11 is larger than the water pressure thrust force to push the piston to form negative pressure in the cavity to open the first liquid inlet, and the detergent is sucked to finish automatic filling.
Since the auxiliary washing with detergent is not required at this time when the rinsing is performed after the dehydration is completed, the bypass cut-off valve is closed, no water flows through the bypass, and the first dispensing device 11 does not perform the automatic dispensing process.
As shown in the control logic diagram of fig. 4, when it is determined that two washing chambers are simultaneously washed, the first dosing device 11 controls the automatic dosing for the first washing chamber 12 and the second dosing device 10 controls the automatic dosing for the second washing chamber 8. When the washing water is fed, the first control valve 4 of the first branch pipeline 2 is opened, water flow enters the first washing chamber 12 and the first branch pipeline 2 from the water inlet pipeline of the first washing chamber 12 respectively, then enters the first throwing device 11 from the first branch pipeline 2, and the first throwing device 11 automatically throws the liquid into the first washing chamber 12 under the action of the water flow. After the automatic liquid feeding process is completed, the water level of the first washing chamber 12 reaches the preset water level and enters the washing process, after the washing process is finished, the washing and dewatering stage is carried out, and the residual water in the first branch pipeline 2 flows into the first washing chamber 12. At this time, negative pressure is formed in the first branch pipeline 2, and the detergent in the detergent containing box 9 is sucked into the first dispensing device 11, thereby completing the automatic detergent filling process of the first dispensing device 11. And (4) after the washing and dewatering are finished, the rinsing water inlet process is carried out, the first control valve 4 is controlled to be closed at the moment, and the rinsing process is carried out when the water level in the first washing chamber 12 reaches the preset rinsing water level.
In the process that the first feeding device 11 finishes automatic feeding and automatic detergent filling, the second feeding device 10 synchronously carries out automatic feeding on the second washing chamber 8 and automatic detergent filling, and the automatic feeding devices of the two washing chambers operate independently and do not interfere with each other. The detailed process is the same as the control of the first washing chamber 12 and the first dispensing device 11, and will not be described herein.
Based on the above scheme, when the first washing chamber 12 and the second washing chamber 8 both execute the washing program, the order of entering the washing and dehydrating is determined according to the input amount of the detergent of the first washing chamber 12 and the second washing chamber 8, and the washing chamber with the large input amount of the detergent preferentially executes the washing and dehydrating. For example, the required amount of detergent to be put into the first washing chamber 12 is 10g, the required amount of detergent to be put into the second washing chamber 8 is 30g, and since the multi-tub washing machine cannot simultaneously perform washing and dewatering, the second washing chamber 8 is controlled to preferentially enter the washing and dewatering program, that is, the second putting device 10 preferentially replenishes the detergent. The reason for this is that the consumption of the second washing chamber 8 is high and less detergent remains in the second dosing device 10 after the dosing of detergent is completed. In case the detergent remaining in the detergent container 9 is not sufficient, the detergent of the second dispensing device 10 is preferably replenished, so as to avoid the second dispensing device 10 from having insufficient detergent when the second washing chamber 8 is subjected to the next washing.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
