A dispensing device 100 according to an embodiment of the utility model is described below with reference to the drawings.

Referring to fig. 4 and 8, a delivery device 100 according to an embodiment of the present invention may include: the liquid storage container 10, the pump body 20 and the driving assembly 30.

Specifically, the liquid container 10 is used for storing the washing liquid, the pump body 20 is mounted to the liquid container 10, and the pump body 20 has a pump head 21. The pump head 21 is movable relative to the reservoir 10 to pump the cleaning solution from the reservoir 10 for dispensing the cleaning solution, thereby facilitating and speeding the pumping of the cleaning solution and controlling the amount of cleaning solution pumped each time.

In some embodiments of the present invention, as shown in fig. 2-4, the driving assembly 30 cooperates with the pump head 21 to drive the pump head 21 to move, so as to pump the washing liquid in the liquid storage container 10 into the washing chamber of the dishwasher, for example, the driving assembly 30 may abut against the pump head 21 and drive the pump head 21 to move in a direction close to the liquid storage container 10, so as to press the pump head 21, so as to pump the washing liquid in the liquid storage container 10 out, so that the washing liquid can be pumped into the washing chamber of the dishwasher, thereby achieving automatic dispensing of the washing liquid, and a user does not need to manually dispense the washing liquid into the washing chamber before washing dishes each time, thereby avoiding pain points caused by manual addition of the washing liquid and frequent dispensing of the washing liquid by the user, making the use of the dishwasher more convenient, and avoiding the occurrence of a situation that the user forgets to dispense the washing liquid and affects the washing effect of the dishes.

And, the in-process of drive assembly 30 drive pump head 21, washing liquid can directly pump into the intracavity that washes the dishes, and do not communicate through other pipelines, can avoid washing liquid to remain to avoid remaining washing liquid to pollute scheduling problem rotten, be favorable to improving dishwasher's health.

In particular, in some embodiments, as shown in fig. 2-5, the drive assembly 30 may comprise a drive member 31 and an actuator member 32, the drive member 31 being connected to the actuator member 32, and the drive member 31 being movable by the drive member 32, the actuator member 32 being adapted to cooperate with the pump head 21 to drive the pump head 21 to move when the actuator member 32 is moved, e.g. to abut against the pump head 21 and to press the pump head 21, thereby enabling pumping of the washing liquid.

In some embodiments, as shown with continued reference to fig. 2-5, the driving member 31 can drive the transmission member 32 to move, thereby moving the pump head 21. For example, in the example shown in fig. 2-5, the driving member 31 can drive the transmission member 32 to move in a first direction (e.g., downward in the up-down direction shown in fig. 4) toward the liquid storage container 10, so that the transmission member 32 abuts against the pump head 21, and the transmission member 32 can drive the pump head 21 to move in a direction toward the liquid storage container 10, thereby dispensing the cleaning solution.

In the washing liquid feeding process, the washing liquid in the liquid storage container 10 is directly pumped into the washing cavity through the pump head 21 and cannot be in contact with the driving assembly 30, and the risk of leakage of the washing liquid is effectively reduced. And the driving member 32 moves along the first direction to drive the pump head 21 to move, so that the driving resistance is smaller, and the phenomenon that the normal feeding of the washing liquid is influenced due to the fact that the driving member 32 or the pump head 21 is jammed is avoided. In addition, the transmission member 32 is abutted against the pump head 21, so that when the pump body 20 or the driving assembly 30 is damaged, only the damaged part needs to be replaced, and the maintenance cost is effectively reduced. In some embodiments where the pump body 20 and the reservoir 10 are removable, the transmission member 32 can also be separated from the pump head 21, which makes the assembly and disassembly easier.

The transmission member 32 may always abut against the pump head 21, or may move a certain distance in a direction approaching the liquid storage container 10 and abut against the pump head 21. For example, in some embodiments, the transmission member 32 is separated from the pump head 21 in the initial position, and the transmission member 32 can move downward a certain distance under the driving of the driving member 31, so that the transmission member 32 abuts against the pump head 21, and the transmission member 32 continues to move downward to drive the pump head 21 to move downward, so as to pump the washing liquid in the liquid storage container 10 into the washing chamber, thereby achieving the automatic dispensing of the washing liquid.

For convenience of description, the orientations of the "up-down direction" and the "left-right direction" in the present invention are based on the orientation relationship shown in the drawings, and are not limited to the orientation in the practical application.

In some embodiments, as shown in FIG. 4, the driving member 31 can also drive the driving member 32 in a first direction away from the reservoir 10 to return the driving member 32 to the initial position and the driving assembly 30 to return to allow the cleaning solution to be dispensed again.

In some embodiments, the pump body 20 further comprises a restoring member (e.g., a restoring spring) for urging the pump head 21 away from the liquid container 10 to restore the pump head 21 to the initial position when the driving assembly 30 is restored, i.e., the driving assembly 30 is in the initial position pressing the pump head 21 and the degree of pressing the pump head 21 is minimized, such as when the driving assembly 30 comprises the driving member 32, and the driving member 32 moves away from the liquid container 10 to restore the driving assembly 30, so that the pump head 21 is restored to the initial position, so that the driving assembly 30 can press the pump head 21 again, e.g., so that the driving member 32 moves toward the liquid container 10 again in the first direction, so that the pump head 21 can move toward the liquid container 10 again. The pump head 21 reciprocates, realizes the throwing in of washing liquid many times, guarantees the throwing in volume of washing liquid, and throws in simple, swift.

For example, as shown in fig. 4, the transmission member 32 can move upward under the driving of the driving member 31 to cancel the downward driving force to the pump head 21, so that the restoring member can drive the pump head 21 to move upward, and the transmission member 32 and the pump head 21 are restored. When the transmission member 32 moves downwards again, the transmission member 32 drives the pump head 21 to move downwards, so that the washing liquid in the liquid storage container 10 is pumped into the washing cavity, and the actions are repeated for multiple times to realize the multiple feeding of the washing liquid and ensure the feeding amount of the washing liquid.

In the related art, a dishwasher controls a feeding device to feed washing liquid through a motor, and controls the feeding amount of the washing liquid by controlling the motor to work for a preset time.

Therefore, in some embodiments of the present invention, as shown in fig. 6 to 8, the dispensing device 100 further includes a dispensing amount detecting mechanism, and the dispensing amount detecting mechanism can be used to detect the liquid amount of the washing liquid pumped by the pump head 21, so as to achieve detection of the dispensing amount of the washing liquid, make the automatic dispensing of the washing liquid more accurate, and avoid problems such as insufficient washing liquid and unclean washing, or excessive washing liquid and unclean rinsing.

In some embodiments of the present invention, the pump head 21 is configured to reciprocate between a first preset position and a second preset position to dispense a cleaning solution. The feeding amount detection mechanism can detect the reciprocating movement times of the pump head 21 so as to obtain the liquid amount of the pumped washing liquid, so that the control of the feeding amount of the washing liquid is more accurate.

The feeding amount is detected according to the reciprocating times of the pump head 21, and is not controlled according to the reciprocating working time of the pump head 21, so that the feeding amount of the washing liquid is not influenced by factors such as the reciprocating speed of the pump head 21, the feeding amount of the washing liquid can be controlled more accurately when the tableware is washed, and the control is convenient.

In addition, can also detect the pump head 21 through input volume detection mechanism and whether reset the circumstances such as, avoid pump head 21 to take place the card dead and influence the washing liquid and normally input.

In some embodiments, as shown in fig. 6-8, the shot size detection mechanism includes a position detection assembly 70, the position detection assembly 70 being used to detect the position of the pump head 21.

Therefore, the number of times, displacement, etc. of reciprocating movement of the pump head 21 can be determined according to the detection result of the position detection assembly 70, and the amount of the cleaning solution can be determined, so that the control of the amount of the cleaning solution can be more accurate. The feeding amount is detected according to the position of the pump head 21, and the feeding amount of the washing liquid is not controlled according to the working time of the pump head 21, so that the feeding amount of the washing liquid can be more accurately controlled when the tableware is washed without being influenced by factors such as the reciprocating speed of the pump head 21 and the like, and the control is convenient.

In addition, the position detection assembly 70 can also detect the driving condition of the driving assembly 30 driving the pump head 21 to move, whether to reset or not, and the like, so as to avoid the influence on normal feeding of the washing liquid caused by the jamming of the driving assembly 30 or the pump head 21.

In some embodiments, the input amount detecting mechanism further includes a control component, the control component is connected to the position detecting component 70 and the driving component 30, and the control component can control the working state of the driving component 30 according to the detection result of the position detecting component 70. For example, when it is judged from the position detection that the amount of the washing liquid put in reaches the required liquid amount, the driving unit 30 may be controlled to stop operating; or when the driving assembly 30 or the pump head 21 is stuck according to the position detection, the driving assembly 30 can be controlled to stop working, and the releasing device 100 can be controlled to send out a fault reminding message to remind a user to perform maintenance.

In some embodiments, when the position detection assembly 70 detects that the pump head 21 has moved to the first preset position, the control assembly counts to determine the shot size, ensuring that the shot size for a single reciprocation of the pump head 21 is fixed and accurate.

In addition, and when the count value reaches the preset threshold value, the control component may control the driving component 30 to stop working. Each time the pump head 21 moves to the first preset position, it indicates that a complete dispensing is completed, and it is ensured that the dispensing amount of each complete dispensing is fixed. The number of times of reciprocating motion of the pump head 21 is controlled to control the number of times of quantitative putting of the washing liquid, so that the putting amount of the washing liquid in each washing process is accurately controlled, the putting precision of the washing liquid is guaranteed, and the washing performance of the dish washing machine is guaranteed.

In some embodiments where the driving assembly 30 includes the driving motor 311, when the count value reaches a predetermined threshold, the control assembly may cut off the power of the driving motor 311, not only stopping the feeding of the washing liquid, but also reducing the energy consumption, saving the electric power, and facilitating the realization of low energy consumption of the dishwasher.

In some embodiments, the preset threshold is greater than or equal to 1, and the specific value may be set according to actual conditions such as the dish washing effect, for example, the preset threshold may be set before leaving a factory or set by a user. In some embodiments, the preset threshold may be 1, 2, 3, 4, 5, etc.

Of course, in an embodiment where the driving assembly 30 comprises the driving member 31 and the transmission member 32, the position detecting assembly 70 may also be used for detecting the position of the transmission member 32, and specifically, the control assembly is configured to count when the position detecting assembly 70 detects that the transmission member 32 moves to the first preset position and control the driving member 31 to stop working when the counted value reaches the preset threshold value, which is also within the protection scope of the present invention.

According to the dispensing device 100 provided by the embodiment of the utility model, the pump head 21 is driven by the driving assembly 30 to move relative to the liquid storage container 10, so that the washing liquid in the liquid storage container 10 is dispensed, automatic dispensing of the washing liquid is realized, pain points caused by manual addition of the washing liquid and frequent dispensing of the washing liquid by a user are solved, and the dishwasher is more convenient to use. The liquid amount of the washing liquid pumped out is detected by the putting amount detection mechanism, so that the putting amount of the washing liquid is more accurately controlled when the tableware is washed, and the control is convenient.

In some embodiments of the present invention, the pump head 21 is movable between a first predetermined position and a second predetermined position, and the pump head 21 is configured to pump the cleaning solution from the reservoir 10 when moved from the first predetermined position to the second predetermined position, thereby dispensing the cleaning solution. When the pump head 21 moves from the second preset position to the first preset position, the pump head 21 can move away from the liquid storage container 10 to be reset.

In some embodiments, the pump body 20 may further include a reset element, and the reset element is used for driving the pump head 21 to move from the second preset position to the first preset position, so as to reset, so as to ensure that the pump head 21 can reciprocate smoothly, and ensure that the pump head 21 can accurately reset to the first preset position at every time, which is beneficial to realizing accurate control of the amount of the washing liquid put in.

For example, in the example shown in fig. 4, the pump head 21 is at a higher height when in the first preset position than when in the second preset position. When pump head 21 is predetermineeing the position by first and is removed to the second, pump head 21 is to the direction removal that is close to stock solution container 10, in order to pump the washing chamber with the washing liquid in the stock solution container 10, when pump head 21 is predetermine the position by the second and is removed to first predetermined position, pump head 21 removes to the direction of keeping away from stock solution container 10, in order to realize resetting of pump head 21, through reciprocating of pump head 21, make washing liquid can pump into the chamber of washing bowl many times, the input volume of washing liquid has been guaranteed. Moreover, the stroke of the reciprocating movement of the pump head 21 is fixed, the feeding amount of the cleaning solution can be controlled by controlling the reciprocating movement times of the pump head 21, and the feeding amount is easier to control.

It should be noted that, the position detecting component may directly detect the position of the pump head 21, or may indirectly detect the position of the pump head 21, which may determine the feeding amount of the cleaning solution, and also has the advantage of accurate control of the feeding amount.
