It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to an embodiment of the present invention, a detergent dispensing device is provided, as shown in fig. 1, which is a schematic structural diagram of an embodiment of the detergent dispensing device of the present invention. The detergent dispensing device may include: the detergent box comprises a detergent box 1, a feeding box 2, a first sensor, a second sensor and a controller.
In an alternative example, the detergent box 1 may be configured to dispense the target amount of detergent to the dispensing box 2 according to the target amount of detergent required for washing the laundry.
For example: the detergent box and the dosing device (e.g. dosing box 2) are divided into two parts.
Optionally, the detergent box 1 is disposed above the input box 2.
For example: the detergent box 1 and the feeding box 2 are arranged up and down.
Therefore, the detergent box and the putting box are arranged up and down, so that the detergent in the detergent box can be conveniently put into the putting box, and the occupied space is small.
Optionally, a bottom outlet of the detergent box 1 is connected to a top inlet of the dosing box 2. And the bottom outlet of the throwing box 2 is communicated to the inlet of the inner cylinder.
Therefore, the detergent box and the putting box are arranged in a vertically separated mode, so that the detergent is conveniently put in, and the putting accuracy of the detergent amount is conveniently controlled.
In an alternative example, the first sensor may be configured to measure a first variation of the amount of the detergent in the detergent box 1.
For example: the first sensor may be configured to measure a first variation of the amount of detergent in the detergent box 1 during a process of putting the detergent box 1 into the putting box 2 by an amount required for washing the laundry.

For example: the second sensor may be configured to measure a second variation of the amount of detergent in the input box 2 during the process of inputting the amount of detergent required for washing the laundry into the input box 2 by the detergent box 1.
In an optional example, the controller may be configured to determine an amount of detergent to be used for washing in an inner tub of a washing machine to be controlled according to a difference between the first variation and the second variation after the first variation or the second variation reaches the target amount.
For example: because the detergent is easy to be hung on the wall, if only one piezoelectric sensor is used, the residual detergent can not participate in the washing process, and the detergent amount participating in the washing each time is inconsistent with the measured amount, so that the washing effect is reduced. The two piezoelectric sensors can sense the measured detergent amount through the difference value of the two piezoelectric sensors, and the measured detergent amount is equal to the detergent amount participating in washing.
For example: the amount of detergent can be controlled by two sensors. For example: the amount of detergent required for washing the laundry is initially calculated, and whether the required amount of detergent is reached may be detected by the first sensor or the second sensor.
From this, through two sensors measure the change volume of detergent volume in the detergent box respectively and put in the change volume of detergent volume in the box, the measuring mode is simple and convenient, and the measuring result precision is good, is favorable to promoting the precision and the reliability of control, and then promotes the precision and the laundry effect of detergent input volume.
Wherein the controller determines the participation amount of the detergent to be participated in the washing in the inner tub of the washing machine to be controlled, and may include: determining whether the first variation and the second variation are equal or whether a difference between the first variation and the second variation is smaller than a preset amount; if the first variation of the amount of the detergent in the detergent box 1 is equal to the second variation of the amount of the detergent in the putting box 2, or the difference between the first variation of the amount of the detergent in the detergent box 1 and the second variation of the amount of the detergent in the putting box 2 is smaller than a preset amount, determining that the second variation is the participation amount.
Therefore, the participation amount of the detergent participating in the washing process is determined according to the variation amount of the detergent in the detergent box and the detergent put in the box, the determination mode is simple and convenient, and the determination structure is accurate and good.
Optionally, the first sensor may include: a first piezoelectric sensor. The second sensor may include: a second piezoelectric sensor.

In an alternative example, the first control switch may be configured to control the detergent box 1 to deliver a target amount of detergent required by laundry to the delivery box 2 by controlling the opening or closing of the outlet at the bottom of the detergent box 1.
In an optional example, the second control switch may be configured to control the participation amount of the detergent put into the inner drum of the washing machine to be controlled by the putting box 2 by controlling the opening or closing of the outlet at the bottom of the putting box 2.
For example: the intelligent feeding method is optimized aiming at the intelligent feeding mode, and a new feeding control method is provided, so that the intelligent feeding accuracy is improved through design on the premise of the prior art, the intelligent feeding control accuracy is improved, and the detergent feeding accuracy is improved.
Therefore, the opening or closing of the bottom outlet of the detergent box is controlled through the first control switch, the opening and closing of the bottom outlet of the feeding box are controlled through the second control switch, the feeding accuracy of the detergent can be accurately controlled, and the washing effect is favorably improved.
In an alternative example, the first control switch and/or the first sensor are provided at a bottom outlet of the detergent box 1.
In an alternative example, the second control switch and/or the second sensor are arranged at the bottom outlet of the drop box 2.
From this, through setting up sensor and controlling means in the bottom exit of corresponding box respectively, it is all very convenient to survey and get and control, and the precision is good.
Optionally, the first control switch may include: a first electromagnetic switch. The second control switch may include: a second electromagnetic switch.
Therefore, the electromagnetic switch is used for controlling, and the control is good in convenience and high in reliability.
In an optional example, the controller may be further configured to turn on the first control switch and turn off the second control switch according to a target amount of detergent required by the laundry to flow the detergent in the detergent box 1 into the input box 2. And the number of the first and second groups,
for example: after the washing machine finishes weighing the clothes in the washing machine barrel, the washing machine calculates the amount of the required detergent, the first electromagnetic switch is turned on, and the detergent flows into the intelligent input port.
In an optional example, the controller may be further configured to close the first control switch and open the second control switch after determining the participation amount, so that the detergent in the dispensing box 2 is dispensed into the inner tub.
For example: and the throwing precision is improved by adopting a difference method.

For example: because the viscosity of the detergent is higher, part of the detergent is stuck on the feeding opening or hung on the side wall of the feeding opening, so that the quantity of the detergent box is reduced by more than the quantity of the detergent box added on the feeding opening.
Therefore, the opening and closing of the first control switch and the second control switch are controlled by adopting a difference method according to the detergent variation in the detergent box and the feeding box, the convenience of controlling the opening and closing of the bottom outlet of the detergent box and the feeding box is good on one hand, and the control accuracy of the variation of the detergent amount is good on the other hand.
In an alternative embodiment, the method may further include: at least one of a load cell and a flush line.
In an alternative example, the load cell may be used to obtain the weight of laundry in the drum.
In an optional example, the controller may be further configured to determine a target amount of detergent required for the laundry according to a weight of the laundry.
For example: after the washing machine finishes weighing the clothes in the washing machine barrel, the washing machine calculates the required amount of the detergent.
Therefore, the target amount of the required detergent is determined according to the weight of the clothes to be washed, the accuracy of determining the target amount of the required detergent is good, the washing effect is guaranteed, and the detergent is saved.
In an alternative example, the flushing pipeline may be used to connect a water pipe to flush the dispensing box 2, so as to flush the detergent adhered above the dispensing box or adhered on the sidewall of the dispensing box into the inner barrel.
For example: the flushing pipeline can be used for communicating a water pipe to flush the putting box 2, so that the detergent adhered to the upper part of the putting box or adhered to the side wall of the putting box is flushed into the inner barrel in the process that the detergent flows into the putting box 2 from the detergent box 1 and/or flows into the putting box from the putting box 2.
For example: the wall built-up residual detergent can be washed away by a water pipe.
For example: the first electromagnetic switch is closed, the second electromagnetic switch is opened, the pipeline connected with the tap water pipe simultaneously starts to feed water to the intelligent feeding port, the water quantity fed in is not required to be large, and the detergent positioned at the intelligent feeding port can be guaranteed to be washed away.
Therefore, the washing agent box is washed through the washing pipeline, the washing agent is stuck above the putting box or hung on the side wall of the putting box in the process of putting the washing agent into the putting box, the washing agent sent out by the washing agent box can be fully put into the washing process as far as possible, on one hand, the washing effect can be improved, and on the other hand, the washing agent can be saved.
Optionally, the flushing line may be arranged in any one or several ways:
for example: the flushing pipeline can be arranged on the side wall of the throwing box 2.
For example: the flushing line may be arranged at the top of the drop box 2.
For example: the flushing pipeline may be disposed on a pipeline between the detergent box 1 and the feeding box 2.
From this, through setting up according to actual demand at the arbitrary suitable position of putting in the box and washing the pipeline, can make the setting of pipeline more convenient with washing on the one hand, on the other hand can promote and wash the effect, and then promotes the washing effect.
Optionally, the flushing pipeline is connected to the water pipe to flush the dispensing box 2, and may include: after the second control switch is turned on, the water pipe is connected to flush the feeding box 2.
From this, through washing after second control switch opens, can promote the washing effect, also can avoid washing in advance to influence and put in the box measuring of detergent received quantity and get accurate nature, or lag washing because detergent viscosity increases and increase and wash the degree of difficulty and influence washing effect and washing effect.
Optionally, the water flow rate of the flushing pipeline for flushing the feeding box 2 can be adjusted according to the size of the feeding box 2.
When the detergent putting device further comprises a controller, the controller can be further used for increasing the water flow of the flushing pipeline if the size of the putting box 2 is larger than a set value. And if the size of the feeding box 2 is smaller than the set value, the water flow of the flushing pipeline is reduced.
For example: the water quantity of the intelligent throwing port is introduced, and the size of the throwing port can be adjusted. For example: when the size of the putting opening is large, the water quantity can be increased; when the size of the putting opening is small, the water quantity can be reduced.
From this, through adjusting the discharge that washes the pipeline according to the size of puting in the box, can guarantee to wash the effect and can not lead to the fact the influence to the installation steadiness of detergent box and puting in the box, the reliability is high, and user experience is good.

Further, the wall built-up residual detergent may be washed by a water pipe.
In an optional example, after the washing machine finishes weighing the clothes in the washing machine barrel, the washing machine calculates the required detergent amount at the moment, the first electromagnetic switch is turned on, and the detergent flows into the intelligent input port. At the moment, the first piezoelectric sensor senses the change of the amount of the detergent in the detergent box, the second piezoelectric sensor senses the change of the amount of the detergent in the intelligent feeding port, when the amount of the detergent in the detergent box is equal to the amount of the detergent in the intelligent feeding port, the first electromagnetic switch is closed, the second electromagnetic switch is opened, meanwhile, a pipeline connected with a water pipe starts to feed water to the intelligent feeding port, the water quantity fed into the intelligent feeding port is not large, and the fact that the detergent in the intelligent feeding port can be washed away can be guaranteed.
Alternatively, due to the high viscosity of the detergent, some detergent may stick on the dispensing opening or hang on the sidewall of the dispensing opening, so that the detergent box is reduced by a larger amount than the dispensing opening is increased.
Optionally, the amount of water that lets in intelligence input mouth can be according to input mouthful size adjustment. For example: when the size of the putting opening is large, the water quantity can be increased; when the size of the putting opening is small, the water quantity can be reduced.
Because the detergent is easy to hang on the wall, if only one piezoelectric sensor is used, the residual detergent can not participate in the washing process, and the detergent quantity participating in the washing each time is inconsistent with the measured quantity, so that the washing effect is reduced. The two piezoelectric sensors can sense the measured detergent amount through the difference value of the two piezoelectric sensors, and the measured detergent amount is equal to the detergent amount participating in washing.
