A dispenser 100 for a washing machine according to an embodiment of the present invention will be described with reference to the accompanying drawings.

Referring to fig. 1 to 14, a dispenser device 100 according to an embodiment of the present invention may include a housing 10, a dispenser mechanism 20, and a cleaning device including a wash piston 30.

Specifically, the housing 10 defines a receiving chamber 110 and a cleaning chamber 120, the receiving chamber 110 is communicated with the cleaning chamber 120, the receiving chamber 110 has a dispensing inlet 111 and a dispensing outlet 112, a liquid such as detergent or softener can be placed in the receiving chamber 110, the dispensing inlet 111 can be opened and closed, when the liquid needs to be dispensed into the receiving chamber 110, the dispensing inlet can be opened, and after the dispensing is completed, the dispensing inlet 111 can be partially or completely closed. The dosing mechanism 20 is adapted to be arranged between the receiving chamber 110 and a washing chamber of the washing apparatus and is capable of controlling a flow of liquid in the receiving chamber 110 to the washing chamber. Specifically, when the dispensing mechanism 20 is opened, the liquid in the accommodating cavity 110 can flow to the washing cavity, so that the dispensing of the washing liquid or the softener and the like is realized; when the throwing is not needed, the throwing device 100 can be closed, and the operation is convenient.

The wash piston 30 is reciprocally disposed within the wash chamber 120 to drive at least a portion of the water within the wash chamber 120 to form a surge stream to wash the receiving chamber 110. Therefore, when the containing cavity 110 needs to be cleaned, the cleaning piston 30 can move in the cleaning cavity 120 in a reciprocating mode, in the process that the cleaning piston 30 moves in the reciprocating mode, water in the cleaning cavity 120 can form impact water flow and flows to the containing cavity 110, impact water cleaning is achieved on the containing cavity 110, and the cleaning effect is good.

It is noted that in the above described embodiment, the impinging water stream is formed by the movement of the wash piston 30. However, in the present invention, the formation of the impinging water stream is not limited to the use of the wash piston 30, and a cleaning device including an impeller and the like may be used, and these will be within the scope of the present invention.

According to the throwing device 100 provided by the embodiment of the invention, the cleaning cavity 120 communicated with the accommodating cavity 110 is arranged, and the cleaning device capable of forming impact water flow is arranged, so that impact water washing can be realized on the accommodating cavity 110, the cleaning effect is good, the effect that the cleaning device can have a good cleaning effect under the condition that the cleaning device is not pulled out or disassembled is achieved, the throwing device can be applied to a flip type throwing device, the effect that the cleaning device can still have a good cleaning effect under the condition that a large capacity is ensured is achieved, and the contradiction between cleaning and capacity is favorably solved.

It can be understood that, in the embodiment of the present invention, the number of the accommodating cavities 110 is not particularly limited, and a plurality of accommodating cavities 110 may be provided as required to implement separate storage and dispensing of the softener, the detergent, and the like, so as to improve the dispensing effect. If necessary, a washing chamber 120 may be provided to communicate with the receiving chamber 110 having a high cleaning requirement, thereby performing the impact washing. Of course, it is also possible to provide a plurality of washing chambers 120, so that each receiving chamber 110 has one washing chamber 120 communicating with it, so that each washing chamber 120 can carry out an impingement water washing.

For example, referring to fig. 1 to 10, in some embodiments of the present invention, the accommodating chamber 110 and the washing chamber 120 are two in one-to-one communication. One of the cleaning chambers 120 can be used for placing detergent to form a detergent chamber, the other cleaning chamber 120 can be used for placing softener to form a softener chamber, impact water washing can be realized in both the detergent chamber and the softener chamber, and the cleaning effect is good.

According to some embodiments of the present invention, the dispensing device 100 may further comprise a piston driver (not shown) connected to the cleaning piston 30 for driving the cleaning piston 30 to move. Therefore, the automatic reciprocating movement of the cleaning piston 30 can be realized through the piston driver, and the cleaning operation is more convenient. Optionally, the piston driver may be a motor driving assembly, a push rod driving assembly, a hydraulic driving assembly, or the like, and different structures may be flexibly selected according to actual situations, which is not particularly limited in the present invention.

Of course, in the embodiment of the present invention, the cleaning piston 30 may be provided as a manual type to achieve manual cleaning. As shown in fig. 1 to 10, an operation opening 121 may be formed on a wall surface of the washing chamber 120 away from the receiving chamber 110, and an operation portion 31 that may protrude through the operation opening 121 may be formed at one end of the piston. Thus, the user can operate the operation unit 31 to reciprocate the cleaning piston 30, and the operability is improved. Alternatively, the operating part 31 may also be connected to a piston driver to achieve an automatic movement of the wash piston 30.

According to some embodiments of the present invention, the dispensing outlet 112 may be a communication port for communicating the accommodating chamber 110 and the washing chamber 120, and as shown in fig. 1 to 8, a liquid passing port 122 may be provided on a wall surface of the washing chamber 120, and the liquid passing port 122 may communicate the washing chamber 120 and the washing chamber. Thus, the open/closed state of the liquid passing port 122 can be switched by the movement of the purge piston 30.

When the cleaning piston 30 moves to a position close to the accommodating chamber 110, for example, as shown in fig. 5 and 6, the liquid passing port 122 is sealed by the cleaning piston 30, and at this time, the liquid in the accommodating chamber 110 cannot flow out; when the wash piston 30 is moved to a position away from the receiving chamber 110, for example, the position shown in fig. 7 or fig. 8, the liquid through port 122 is no longer sealed by the wash piston 30, and is in an open state, and the liquid in the receiving chamber 110 can flow to the washing chamber under the action of the dosing mechanism 20. Therefore, the liquid can be put in by controlling the cleaning piston 30 and the putting mechanism 20, the putting operation is more reliable, the phenomenon that the putting mechanism 20 is opened by mistake when the putting is not carried out to cause the putting is avoided, and meanwhile, the structure is more compact.

Further, as shown in fig. 1 to 8, a cleaning port 123 may be further provided on a wall surface of the cleaning chamber 120, the cleaning port 123 is communicated with the outside or the washing chamber, the cleaning port 123 is spaced apart from the liquid passing port 122 in a moving direction of the cleaning piston 30, and the cleaning port 123 is disposed away from the accommodating chamber 110. This also allows the cleaning port 123 to be opened and closed by controlling the position of the cleaning piston 30. When the cleaning port 123 is moved to the position shown in fig. 5 or fig. 7, the cleaning port 123 may be in a closed state; when the purge port 123 is moved to the position shown in fig. 8, the purge port 123 may be opened. Thereby, a better cleaning of the receiving chamber 110 can be achieved.

Specifically, the dosing device 100 may have three states depending on the position of the wash piston 30. When the cleaning piston 30 is at the first position shown in fig. 5 and 6, the cleaning port 123 and the liquid passing port 122 are both in a closed state, and the liquid can be stably stored in the accommodating cavity 110, and the dispensing operation is not performed; when the cleaning piston 30 is at the second position shown in fig. 7, the cleaning port 123 is in a closed state, and the liquid passing port 122 is in an open state, at this time, the liquid can be thrown in by controlling the throwing mechanism 20; when the cleaning piston 30 is at the third position shown in fig. 8, the cleaning port 123 and the liquid passing port 122 are both in an open state, and at this time, the liquid in the accommodating chamber 110 can flow to the outside or the washing chamber through the cleaning port 123.

When the washing device is working normally, the cleaning piston 30 can be located at the second position to provide a condition for putting, when liquid putting is needed, the liquid putting can be carried out by controlling the putting mechanism 20, and liquid such as detergent can be mixed with water in the water inlet cavity 130 and then flows into the washing cavity to wash clothes.

When a user needs to clean the accommodating chamber 110, in order to ensure an excellent cleaning effect, the following steps are performed:

firstly, waste liquid cleaning is carried out: the wash piston 30 is moved away from the receiving chamber 110 to a third position, in which residual detergent in the receiving chamber 110 can be discharged from the wash port 123 to the outside of the washing apparatus or into the wash chamber.

Then, a clean water wash may be performed: after the detergent is completely discharged, a large amount of clean water is added from the feeding inlet 111 to preliminarily flush the accommodating cavity 110, and the waste water can be discharged from the cleaning port 123 again.

Thereafter, a powerful flush with the purge piston 30 may be performed: when the receiving chamber 110 is too dirty to clean in the above two steps, the wash piston 30 may be actuated into a power flush mode. Specifically, the cleaning piston 30 can be controlled to be switched between the first position and the third position without stopping and rapidly, reciprocating motion similar to that of the piston is performed, impact water flow can be generated at the moment, impact powerful washing is performed on the accommodating cavity 110 from the communication position of the accommodating cavity 110 and the cleaning cavity 120, and the cleaning effect is good.

After the cleaning is completed, the cleaning piston 30 may be moved to the third position so that the waste water may be discharged again from the cleaning port 123 to complete the cleaning operation. The wash piston 30 may then be moved to a second position in preparation for a normal wash function.

From this, hold chamber 110 and can carry out the washing of many times different degree, the cleaning performance promotes greatly, and abluent waste liquid can be discharged through washing mouth 123 simultaneously, avoids flowing into input mechanism 20, causes secondary pollution to input mechanism 20.

Referring to fig. 1 to 10, the cleaning chamber 120 may be formed in a cylindrical shape, the cleaning port 123 and the liquid passing port 122 may be formed on a side wall surface of the cleaning chamber 120, and the cleaning piston 30 may move along a central axis of the cleaning chamber 120, so that the arrangement is convenient, and the switching effect of opening and closing is good. Alternatively, the washing chamber 120 may be formed in a cylindrical shape, which is beautiful in shape and has good water permeability.

The structure of the purge piston 30 will be further described below.

As shown in fig. 5 to 10, the wash piston 30 may include an operating portion 31 and a piston main body 32, the piston main body 32 being provided in the wash chamber 120, the operating portion 31 being connected to the piston main body 32 and protruding from the operating port 121. The reciprocating movement of the piston main body 32 in the cleaning chamber 120 can be realized by controlling the operation portion 31, and the closing of the cleaning port 123 or the liquid passing port 122 by the piston main body 32 can be realized.

In some embodiments of the present invention, the cleaning piston 30 may not have the operation portion 31, and in this case, the piston main body 32 may be driven to move by other structures, for example, the piston main body 32 is configured to be a magnetic structure, and the reciprocating movement of the piston main body 32 is achieved by the action of a magnetic field, so that the mobility and the sealing performance are good.

The operation part 31 may be formed as an operation rod having a tip with an outer diameter larger than an inner diameter of the operation port 121, the operation rod being connected to the piston main body 32, and the cross-section of the operation rod may be formed like a cross structure to improve strength. A sealing protrusion 321 that abuts against the inner circumferential wall surface of the wash chamber 120 may be formed on the outer circumferential surface of the piston main body 32. This reduces the contact area between the piston body 32 and the inner peripheral wall surface of the wash chamber 120, reduces friction, and reduces the movement resistance of the wash piston 30, thereby making the movement more flexible. Alternatively, as shown in fig. 9 and 10, a sealing protrusion 321 may be provided adjacent to an end of the piston main body 32, and the sealing protrusion 321 may be made of a flexible material such as rubber or silicone to improve sealing effect.

So as to realize the simultaneous or separate administration of a plurality of liquids. The structure in which the driving of the plurality of dosing pumps 21 is realized by one driving motor 22 is understood and easily realized by those skilled in the art, and will not be described in detail herein.

Referring to fig. 1 to 4, according to some embodiments of the present invention, an inlet chamber 130 may be further disposed in the housing 10, the inlet chamber 130 is spaced apart from the accommodating chamber 110, the inlet chamber 130 has an inlet 131 and an outlet 132, the outlet 132 may be communicated with the washing chamber, and the dispensing mechanism 20 may be disposed between the accommodating chamber 110 and the inlet chamber 130 to control the liquid in the accommodating chamber 110 to flow to the inlet chamber 130.

From this, put in device 100 and intake structure integration together, under the effect of putting in mechanism 20, the liquid that holds in the chamber 110 can enter into intake chamber 130, and simultaneously water also can enter into intake chamber 130 in, liquid such as detergent can realize mixing in intake chamber 130 with water, mixes liquid and can follow delivery port 132 outflow to flow to the washing chamber, and at this moment, liquid such as washing liquid can mix with water before getting into the washing chamber, can promote the washing effect.

Of course, the driving motor 22 may also be connected to the control system 400 of the washing apparatus, and the control system 400 of the washing apparatus may realize automatic control of the driving motor 22, and at this time, the dispensing device 100 may form an automatic structure, i.e., an automatic dispensing device. When dosing is required, the control system 400 can calculate the detergent to be dosed and then send a command to the drive motor 22 to drive the dosing pump 21 to pump liquid into the washing chamber.

Referring to fig. 1 to 14, the dispensing device 100 according to the embodiment of the present invention may further include a liquid level detecting device 40, and the liquid level detecting device 40 may extend into the accommodating chamber 110 for detecting a liquid level in the accommodating chamber 110. Therefore, a user can know the liquid level in the accommodating cavity 110 clearly, and detergent, softener and the like can be added in time when the liquid level is insufficient. The liquid level detection device 40 can also be connected with the control system 400 of the washing equipment to realize automatic detection, and the detection effect is good.

Alternatively, the level detection device 40 may be disposed adjacent to the wash chamber 120. Therefore, the impact water flow generated by the cleaning piston 30 can be more easily impacted to the liquid level detection device 40, so that the liquid level detection device 40 can be cleaned more thoroughly. For example, in the embodiment shown in fig. 1 to 5, the liquid level detection device 40 may also face the communication between the accommodating chamber 110 and the cleaning chamber 120, and in this case, the impact water flow may directly impact the liquid level detection device 40, so that the cleaning effect is excellent.
