Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and in particular, relates to a control method for a dispensing device of washing equipment. Background Art

[0002] When using a washing machine to wash clothes, detergents, softeners and other clothing treatment agents need to be added to achieve better washing results. Clothing treatment agents can be added manually by the user, or automatically by an automatic dispensing device. When the user manually adds clothing treatment agents, it is impossible to accurately control the amount of clothing treatment agents added, and the optimal washing effect may not be achieved. Most of the current automatic dispensing devices put a preset amount of clothing treatment agents into the laundry machine at one time in the middle stage of the water intake process. The clothing treatment agents are relatively concentrated in the water, and the required dispersion and dissolution time is relatively long, which affects the effect of the clothing treatment agents.

[0003] On the other hand, the amount of clothing treatment agent used is closely related to the amount of water used. In order to achieve accurate control of the amount of clothing treatment agent added, the automatic dispensing device needs to obtain the water intake of this operation in advance, so as to calculate the corresponding amount of clothing treatment agent to be added and dispensed during the water intake process. However, since the automatic dispensing device can only obtain the set water intake of the program before the water intake is completed, the set water intake may deviate from the final actual water intake, which will cause the amount of clothing treatment agent added to not be the optimal amount under the actual water intake.

[0004] As for the external dispensing device that is independent of the washing equipment, since the external dispensing device and the washing equipment have different control systems, it is necessary to establish a communication connection between the control systems of the two so that the external dispensing device can obtain the water intake of the washing equipment, which increases the production cost. Otherwise, the user needs to manually set the dispensing amount on the external dispensing device, or set the water intake, and then the external dispensing device automatically calculates the dispensing amount. The user's operation is cumbersome, and there is also the problem of inaccurate dispensing amount.

[0005] In view of this feature, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a control method for a dispensing device of a washing machine to achieve uniform distribution of clothing treatment agent in water while accurately controlling the amount of clothing treatment agent dispensed.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A control method for a dispensing device for a washing machine, the dispensing device comprising a flow sensor for detecting the amount of water inflow into the washing machine; after the flow sensor detects the start of water inflow, the dispensing device intermittently dispenses clothing treatment agent during the water inflow process of the washing machine.

[0009] Furthermore, the flow sensor continuously detects the water intake during the water intake process of the washing device, and the dispensing device determines the start time and interval of dispensing the clothes treatment agent according to the water intake detected by the flow sensor, and performs intermittent dispensing of the clothes treatment agent;

[0010] Preferably, the delivery device comprises a control system independent of the washing equipment, and the control system is electrically connected to the flow sensor.

[0011] Furthermore, the intermittent delivery of the laundry treatment agent by the delivery device specifically includes the following delivery process:

[0012] After the flow sensor detects that the washing device starts to take in water, when the detected water intake reaches the first preset water intake X1, the dispensing device performs the first dispensing step of the first preset dispensing amount S1;

[0013] After the first delivery step is completed, each time the flow sensor detects water inflow of a second preset water inflow volume X2, the delivery device executes a second delivery step of a second preset delivery volume S2;

[0014] When the flow sensor detects that the water inflow stops for a preset time T0, the delivery device ends the delivery process;

[0015] Among them, X1>X2, S1>S2.

[0016] Furthermore, the first preset water inflow X1 and the first preset delivery amount S1 are set to satisfy: S1 / X1=S2 / X2;

[0017] Preferably, X1=nX2, S1=nS2, n is an integer greater than 1;

[0018] More preferably, the first delivery step includes the delivery device executing the second delivery step n times.

[0019] Furthermore, the dispensing device receives setting information of the user to determine the washing program and / or the type of dispensing of the laundry treatment agent, and determines the second preset dispensing amount S2 according to the washing program and / or the type of dispensing of the laundry treatment agent.

[0020] Furthermore, the delivery device further comprises a water quality sensor for detecting the quality of water entering the washing equipment;

[0021] The control method further comprises: after the flow sensor detects that water starts to enter, the water quality sensor detects the water quality of the entering water, and the delivery device corrects the second preset delivery amount S2 according to the detection result of the water quality sensor;

[0022] During the water intake process of the washing machine, the dispensing device intermittently dispenses the clothes treating agent according to the corrected second preset dispensing amount S2'.

[0023] Furthermore, the dispensing device also determines whether clothes treatment agent is dispensed during the current water inflow according to the water inflow times of the washing device detected by the flow sensor;

[0024] Preferably, the delivery device further comprises a communication module, wherein the communication module is in communication connection with a mobile terminal, and the mobile terminal receives setting information of a user and sends the setting information to the delivery device.

[0025] Furthermore, the dispensing device comprises at least a first liquid storage chamber for containing detergent and a second liquid storage chamber for containing softener;

[0026] After receiving the start command, the dispensing device dispenses detergent when the flow sensor detects the first water inflow to the washing device; and dispenses softener when the flow sensor detects the Nth water inflow to the washing device; wherein N≥2;

[0027] Preferably, when the flow sensor detects the second to N-1th water inflow into the washing device, the dispensing device does not dispense clothing treatment agent, wherein N≥3.

[0028] Furthermore, when counting the number of water inflows, if the flow sensor detects that the water inflow stops, and does not detect the start of water inflow within the preset time T0, the delivery device determines that the current water inflow stage is over, and after the flow sensor detects the start of water inflow again, the number of water inflows increases by one;

[0029] If water inflow is detected again within the preset time T0, the number of water inflows will not be counted until the flow sensor detects that the continuous cessation of water inflow reaches the preset time T0, and the delivery device determines that the current water inflow stage is over.

[0030] Furthermore, a reset button is provided on the delivery device. After the delivery device receives a signal indicating that the reset button is triggered, when the flow sensor detects that water starts to flow in again, this water flow is counted as the first water flow.

[0031] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0032] The dispensing device of the present invention intermittently dispenses clothing treatment agent during the water intake process of the washing device, so that the clothing treatment agent is evenly distributed in the water during the water intake process, and then more easily dispersed and fully dissolved in the water during the subsequent washing process, so as to achieve better washing effect.

[0033] The dispensing device of the present invention controls the dispensing of the laundry treatment agent according to the water inflow detected by the flow sensor, and dispenses a fixed amount of the laundry treatment agent at each fixed water inflow interval, so that the dispensing amount of the laundry treatment agent and the water inflow always maintain a certain ratio, and when the dispensing device does not know the total water inflow of the washing device in advance, the dispensing amount of the laundry treatment agent can also be accurately controlled. The setting value of the first preset water inflow X1 is greater than the second preset water inflow X2, which can ensure that when the dispensing device dispenses the laundry treatment agent for the first time, there is already enough water in the washing device to prevent the laundry treatment agent from being directly absorbed by the clothes.

[0034] The dispensing device of the present invention also detects the water quality of the incoming water by setting a water quality sensor, and then corrects the second preset dispensing amount S2, so that the dispensing amount of the clothing treatment agent can be adjusted under different water qualities to achieve the best washing effect.

[0035] The dispensing device of the present invention controls the dispensing of clothing treatment agent according to the number of water inflows of the washing device. The dispensing device can correctly dispense clothing treatment agent at the corresponding operation stage without obtaining the operation status of the washing device, and the control logic is simple. When the water inflow stop time is less than T0, the dispensing device does not count the number of water inflows at the beginning of this water inflow, so as to prevent intermittent water inflow caused by unstable water pressure in the use environment or other conditions, which may cause program misjudgment.

[0036] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Embodiment 1

[0046] This embodiment provides a control method for a dispensing device of a washing device, which is used to dispense clothing treatment agent into the washing device. The washing device includes but is not limited to a pulsator washing machine, a drum washing machine and a washer-dryer.

[0047] The dispensing device described in this embodiment includes a flow sensor for detecting the amount of water inflow into the washing device. After the flow sensor detects the start of water inflow, the dispensing device intermittently dispenses clothing treatment agent during the water inflow process of the washing device.

[0048] Furthermore, the flow sensor continuously detects the water intake during the water intake process of the washing device, and the dispensing device determines the start time and interval of dispensing the clothing treatment agent according to the water intake detected by the flow sensor, and performs intermittent dispensing of the clothing treatment agent.

[0049] In the above scheme, the dispensing device intermittently dispenses clothing treatment agent during the water inlet process of the washing device. Compared with the method of dispensing clothing treatment agent once in the middle stage of the water inlet process in the prior art, the clothing treatment agent can be evenly distributed in the water during the water inlet process, and then it is easier to evenly disperse and fully dissolve in the water during the subsequent washing process, so as to achieve a better washing effect.

[0050] In this embodiment, the delivery device can be a delivery device integrated into the washing device in the prior art, and adopts the same control system as the washing device body. The delivery device can also include a control system independent of the washing device, the control system is electrically connected to the flow sensor to obtain the water intake of the washing device, and the delivery device is independently controlled by the control system.

[0051] When the washing device and the dispensing device have independent control systems respectively, the dispensing device can be an external dispensing device arranged outside the washing device, and thus is not limited by the size of the washing device body, thereby storing more types and larger quantities of clothing treatment agents.

[0052] There can be a communication connection between the delivery device and the washing equipment, so that the delivery device can directly obtain the operating status of the washing equipment, thereby more accurately controlling the delivery process. When there is no communication connection between the delivery device and the washing equipment, the delivery device can also detect the water inflow process of the washing equipment through a flow sensor, thereby realizing the control of the delivery process.

[0053] In this embodiment, the delivery device includes a water inlet end connected to an external water source, and a water outlet end connected to a water inlet valve of the washing device, and the flow sensor is arranged between the water inlet end and the water outlet end. During operation, the washing device controls the start and stop of water inlet by controlling the opening and closing of the water inlet valve, and the delivery device can determine whether the washing device is being supplied with water by whether the flow sensor detects the water flow passing through.

[0054] In this embodiment, when the delivery device is an external delivery device arranged outside the washing device, specifically, the external delivery device includes a water inlet pipeline, a delivery pipeline, and a liquid storage chamber for holding the laundry treatment agent. The two ends of the water inlet pipeline are respectively connected to the water inlet end and the water outlet end of the external delivery device. The two ends of the delivery pipeline are respectively connected to the liquid storage chamber and the water inlet pipeline, and a delivery mechanism, such as a liquid pump, is arranged on the delivery pipeline for delivering the laundry treatment agent into the water inlet pipeline. The flow sensor is arranged on the water inlet pipeline.

[0055] When in use, the water inlet end of the external dispensing device is connected to the external water source, and the water outlet end is connected to the water inlet valve of the washing device. When the washing device is filled with water, the water inlet valve of the washing device is opened, and the external water source passes through the water inlet pipeline of the external dispensing device, and then enters the washing device from the water inlet valve of the washing device. The dispensing mechanism dispenses the clothing treatment agent in the liquid storage chamber into the water inlet pipeline, so that the clothing treatment agent enters the washing device together with the water in the water inlet pipeline.

[0056] like Figure 1 As shown, in a further solution of this embodiment, the dispensing device intermittently dispenses the clothing treatment agent, which specifically includes the following dispensing process:

[0057] After the flow sensor detects that the washing device starts to take in water, when the detected water intake reaches the first preset water intake X1, the dispensing device performs the first dispensing step of the first preset dispensing amount S1;

[0058] After the first delivery step is completed, each time the flow sensor detects water inflow of a second preset water inflow volume X2, the delivery device executes a second delivery step of a second preset delivery volume S2;

[0059] When the flow sensor detects that the water inflow stops for a preset time T0, the delivery device ends the delivery process.

[0060] Among them, X1>X2, S1>S2.

[0061] Preferably, the first preset water inflow X1 and the first preset delivery amount S1 are set to satisfy: S1 / X1=S2 / X2.

[0062] More preferably, X1=nX2, S1=nS2, and n is an integer greater than 1.

[0063] In the above scheme, the dispensing device dispenses a second preset amount S2 of clothing treatment agent into the washing device each time it detects the second preset water inlet volume X2, so that the amount of clothing treatment agent dispensed and the water inlet volume are always maintained at a certain ratio. Even if the dispensing device does not know the total amount of water inlet of the washing device in advance, precise control of the amount of clothing treatment agent dispensed can be achieved.

[0064] The setting value of the first preset water inlet volume X1 is greater than the second preset water inlet volume X2, which can ensure that there is enough water in the washing device when the dispensing device dispenses the clothes treatment agent for the first time. Especially for a drum washing machine, the water inlet volume before the first dispensing of the clothes treatment agent is large, and the drain outlet in the drum can be filled first, thereby avoiding the situation where the clothes treatment agent is directly absorbed by the clothes and cannot be fully dissolved in the water.

[0065] In a preferred solution of this embodiment, the first delivery step includes the delivery device executing the second delivery step n times, which further simplifies the control logic of the delivery device.

[0066] Furthermore, the dispensing device receives setting information of the user to determine the washing program and / or the type of dispensing of the laundry treatment agent, and determines the second preset dispensing amount S2 according to the washing program and / or the type of dispensing of the laundry treatment agent.

[0067] In the above solution, different second preset dosing amounts S2 corresponding to different washing programs and different types of laundry agents are built into the control system of the dosing device and can be directly called when dosing laundry agents. For example, the second preset water intake X2 preset for the dosing device is 1 L. Under the normal washing program, the second preset dosing amount S2 of the concentrated laundry detergent is 1 g, and the second preset dosing amount S2 of the ordinary laundry detergent is 2 g. Under the washing program corresponding to stubborn stains, the second preset dosing amount S2 of the concentrated laundry detergent is set to 1.5 g, and the second preset dosing amount S2 of the ordinary laundry detergent is set to 3 g.

[0068] In this embodiment, when the washing equipment and the dosing device each have an independent control system, the user can perform settings by directly operating on the dosing device. Specifically, the dosing device has an operation panel for the user to operate. The operation panel includes a number of function keys, or the operation panel is a touch display screen. The user can perform program settings for the dosing device through the operation panel. The operation panel is electrically connected to the control system of the dosing device and sends the user's setting information to the control system.

[0069] Alternatively, the user can also perform settings on the dosing device through a mobile terminal. Specifically, the dosing device includes a communication module. The communication module is communicatively connected to the mobile terminal. The mobile terminal receives the user's setting information and sends the setting information to the communication module of the dosing device. The communication module is electrically connected to the control system of the dosing device and sends the user's setting information to the control system.

[0070] In a further solution of this embodiment, the dosing device further includes a water quality sensor for detecting the water quality of the water inlet of the washing equipment.

[0071] The control method further includes: after the flow sensor detects the start of water inlet, the water quality sensor detects the water quality of the water inlet, and the dosing device corrects the second preset dosing amount S2 according to the detection result of the water quality sensor. During the water inlet process of the washing equipment, the dosing device intermittently doses the laundry agent according to the corrected second preset dosing amount S2'.

[0072] Specifically, the dosing device in this embodiment detects the hardness of the water inlet and presets a first hardness parameter H1 and a second hardness parameter H2, where H1 < H2. The dosing device presets a first correction coefficient α and a second correction coefficient β, where α < 1 and β > 1.

[0073] The hardness parameter detected by the water quality sensor is H. When H < H1, that is, when the water quality is relatively soft, the corrected second preset dosage S2' = αS2. When H > H2, that is, when the water quality is relatively hard, the corrected second preset dosage S2' = βS2. When H1 < H < H2, no correction is performed, and the original second preset dosage S2 is directly used for dosing.

[0074] The hardness of water reflects the total concentration of calcium and magnesium ions in the water. The larger the hardness parameter, the higher the ion concentration. Water with a relatively high hardness may react with the laundry treatment agent added, generating some substances insoluble in water, reducing the actual concentration of the laundry treatment agent, and affecting the laundry effect. In the above solution, by detecting the hardness of the incoming water and presetting the hardness parameter and correction coefficient, the dosing amount of the laundry treatment agent can be appropriately adjusted under different incoming water qualities, so as to achieve the optimal laundry effect under different water qualities.

[0075] In this embodiment, the dosing device intermittently doses the laundry treatment agent during the water inlet process of the washing equipment, so that the laundry treatment agent is evenly distributed in the water during the water inlet process, and then is more likely to be evenly dispersed and fully dissolved in the water during the subsequent laundry process, so as to achieve a better laundry effect. At the same time, the dosing device doses a fixed amount of laundry treatment agent at each interval of a fixed water inflow, so that the dosing amount of the laundry treatment agent and the water inflow always maintain a certain ratio. The dosing device does not need to know the total water inflow of the washing equipment in advance, and can achieve precise control of the dosing amount of the laundry treatment agent.

[0076] Embodiment 2

[0077] As Figure 2 shown, this embodiment is a further limitation of the above Embodiment 1. The dosing device also judges whether to dose the laundry treatment agent for the current water inlet according to the number of water inlets of the washing equipment detected by the flow sensor.

[0078] In the above solution, the dosing device directly controls the dosing process of the laundry treatment agent according to the number of water inlets of the washing equipment. For a laundry program that needs to dose different types of laundry treatment agents at different operating stages, the dosing device can automatically dose the corresponding laundry treatment agent at a specific operating stage without obtaining the operating process of the washing equipment. The control logic of the dosing device is simple and easy to implement.

[0079] In this embodiment, the delivery device may further include a communication module, the communication module is connected to the mobile terminal for communication, the mobile terminal receives the user's setting information, and sends the setting information to the delivery device. The user can send control instructions to the delivery device by operating the mobile terminal to set the running program of the delivery device. There is no need to set an operation panel on the delivery device body, thereby simplifying the structure of the delivery device, and also realizing the user's remote control of the delivery device, which is more convenient to use.

[0080] In a further solution of this embodiment, the dispensing device includes at least a first liquid storage chamber for containing detergent and a second liquid storage chamber for containing softener.

[0081] After receiving the start command, the dispensing device dispenses detergent when the flow sensor detects the first water inflow of the washing device. The softener is dispensed when the flow sensor detects the Nth water inflow of the washing device. Where N≥2.

[0082] Preferably, when the flow sensor detects the second to N-1th water inflow into the washing device, the dispensing device does not dispense clothing treatment agent, wherein N≥3.

[0083] In the above scheme, the washing program of the washing device includes a washing stage and N-1 rinsing stages. Water needs to be refilled at the beginning of each stage, and the total number of water inflows in running a washing program is N. The dispensing device counts the number of water inflows, so as to automatically dispense detergent when water is inflowed in the washing stage and dispense softener when water is inflowed in the last rinsing stage, without the need for user operation.

[0084] The total number of water intake times N may be a preset value, and at this time the dispensing device can only be applied to one of the above-mentioned washing programs.

[0085] The total number of water inflows N can also be manually set by the user before starting the dispensing device. The dispensing device receives the total number of water inflows information set by the user, determines the total number of water inflows N when the washing device runs a washing program, and then controls the dispensing process of the laundry treatment agent. In this case, the same dispensing device can be used for different washing programs, which is more convenient for users.

[0086] In a further scheme of this embodiment, when counting the number of water inflows, if the flow sensor detects that the water inflow has stopped and the start of water inflow is not detected within the preset time length T0, the delivery device determines that the current water inflow stage is over, and after the flow sensor detects the start of water inflow again, the number of water inflows increases by one.

[0087] If water inflow is detected again within the preset time T0, the number of water inflows will not be counted until the flow sensor detects that the continuous cessation of water inflow reaches the preset time T0, and the delivery device determines that the current water inflow stage is over.

[0088] In the above scheme, if the water supply stop time before the start of water supply is less than T0, the dispensing device will not count the number of water supply times for this start of water supply, so as to prevent intermittent water supply caused by unstable water pressure in the use environment or other conditions, resulting in program misjudgment and incorrect dispensing of clothing treatment agent by the dispensing device.

[0089] In a further solution of this embodiment, a reset button is provided on the delivery device. After the delivery device receives a signal that the reset button is triggered, when the flow sensor detects that water starts to flow in again, this water flow is counted as the first water flow.

[0090] In the above scheme, when a complete washing program is completed, the user resets the dispensing device by triggering the reset button. When the dispensing device is operated next time, the water inflow times are re-counted to execute the dispensing process. When the washing device is interrupted by special conditions during operation, it may be necessary to re-run the washing program in some cases. At this time, the user can trigger the reset button to reset the dispensing device, so that the dispensing device re-counts the water inflow times and executes the dispensing process.

[0091] In this embodiment, the delivery device controls the delivery process of the laundry treatment agent according to the number of water intakes of the washing device. The delivery device does not need to obtain the operation process of the washing device, and can deliver the corresponding laundry treatment agent at a specific operation stage. The control logic of the delivery device is simple. In particular, for a delivery device controlled by a control system independent of the washing device, there is no need to establish a communication connection between the delivery device and the washing device to obtain the operation process of the washing device, so that the same delivery device can be applied to different washing devices without the need for complex operations such as connection and binding, and is more convenient to use.

[0092] Embodiment 3

[0093] like Figure 3 As shown, the difference between this embodiment and the above-mentioned embodiment 2 is that: the delivery device receives delivery process information set by the user, and delivers the clothing treatment agent according to the delivery process information.

[0094] Specifically, the dispensing device comprises at least two liquid storage chambers for containing different types of laundry treating agents.

[0095] The delivery device receives delivery process information set by a user, wherein the delivery process information includes whether clothes treating agent is delivered each time water is inflowed during the current operation of the washing device, and the type of clothes treating agent delivered.

[0096] After the dispensing device receives the start instruction, each time the flow sensor detects water inflow into the washing device, the dispensing device dispenses the clothes treatment agent according to the dispensing process information.

[0097] In this embodiment, for the delivery device including a communication module, the user can set the delivery process through the mobile terminal, and the mobile terminal directly sends the delivery process information set by the user to the delivery device. The setting of the delivery process needs to be set separately for each water inflow, and the operation is relatively complicated. Mobile terminals such as mobile phones can provide a control interface that is easy for users to operate by installing corresponding apps, making the setting more convenient. At the same time, there is no need to set a complex operation panel on the delivery device, which simplifies the structure of the delivery device.

[0098] Different from the solution in Example 2 where the delivery module can only deliver detergent and softener, in the above solution, the delivery module can deliver various types of clothing treatment agents at different stages of the washing process, and the delivery of clothing treatment agents is not limited to the first water inlet and the last water inlet, so that the delivery module can be applied to more complex washing processes, thereby achieving detailed washing and care for special clothes.

[0099] For example, the dispensing device includes three liquid storage chambers, which respectively contain detergent, softener and disinfectant.

[0100] When using the dispensing device for automatic dispensing, the user sets the washing program for this operation on the washing device as pre-wash-wash-rinse 3 times, that is, the total number of water intakes in the washing program is 5 times. Then the user operates the dispensing device to set the dispensing process. Specifically, the dispensing process information set by the user includes: disinfectant is dispensed in the first water intake, detergent is dispensed in the second water intake, clothing treatment agent is not dispensed in the third and fourth water intakes, and softener is dispensed in the fifth water intake. After the user completes the setting of the dispensing process, the dispensing device is started, and then the washing device is started to start the operation of the washing program.

[0101] During the washing program, the dispensing device dispenses clothing treatment agent according to the dispensing process information set by the user. When the flow sensor detects the first water inflow, the dispensing device controls the dispensing mechanism connected to the disinfectant storage chamber to operate and dispense disinfectant. When the flow sensor detects the second water inflow, the dispensing device controls the dispensing mechanism connected to the detergent storage chamber to operate and dispense detergent. When the flow sensor detects the third and fourth water inflows, the dispensing device does not dispense. When the flow sensor detects the fifth water inflow, the dispensing device controls the dispensing mechanism connected to the softener storage chamber to operate and dispense softener. After the fifth water inflow, the dispensing device ends the dispensing process and enters the standby state.

[0102] In a preferred solution of this embodiment, the delivery process information also includes the delivery amount of the laundry treatment agent each time the water is added. When the user sets the delivery process, for each time the laundry treatment agent needs to be delivered to the water, the second preset delivery amount S2 of the corresponding laundry treatment agent is also set. During operation, the delivery device executes the delivery process of the corresponding laundry treatment agent according to the second preset delivery amount S2 set by the user.

[0103] In this embodiment, the dispensing module receives the set dispensing process information to determine whether the clothes treatment agent needs to be dispensed each time the water enters. When the user sets the dispensing process of the dispensing module, each water inflow is set separately, which is particularly suitable for the case where the user sets the washing device to run a custom washing program. The dispensing device runs according to the dispensing process set by the user and can flexibly adapt to a variety of washing programs.

[0104] Embodiment 4

[0105] like Figure 4 As shown, the difference between this embodiment and the above-mentioned embodiment 2 is that: the delivery device receives the washing program information selected by the user, and calls the delivery program corresponding to the selected washing program to deliver the clothes treatment agent.

[0106] Specifically, the washing machine has multiple washing programs, the dispensing device has multiple dispensing programs, and the multiple dispensing programs of the dispensing device correspond one to one with the multiple washing programs of the washing machine. The dispensing program includes whether to dispense clothing treatment agent each time water is supplied when the washing machine runs the corresponding washing program.

[0107] The delivery device receives the washing program information selected by the user and determines the washing program to be run by the washing device this time.

[0108] After receiving the start instruction, the dispensing device dispenses the clothes treatment agent according to the dispensing program corresponding to the washing program selected by the user each time the flow sensor detects water inflow into the washing device.

[0109] Preferably, the dispensing device comprises at least two liquid storage chambers for containing different types of clothing treatment agents, and the dispensing program further comprises the type of clothing treatment agent dispensed each time water is introduced when the washing device runs the corresponding washing program.

[0110] In the above scheme, the dispensing device pre-stores a plurality of dispensing programs corresponding to different washing programs. When using the dispensing device for automatic dispensing, the user selects the washing program to be run on the washing device, and then operates on the dispensing device to select the same washing program. The dispensing device can call the corresponding dispensing program, and then complete the corresponding dispensing process according to the number of water inflows detected after starting. The user does not need to set it separately for each water inflow, which reduces the user's operation and is convenient to use.

[0111] For example, the normal washing program includes one washing process and two rinsing processes. The corresponding normal washing program is to add detergent in the first water inlet, no clothing treatment agent in the second water inlet, and softener in the third water inlet. The single rinse program only includes one rinse. The corresponding single rinse program is to add softener in the first water inlet.

[0112] When the user wants to perform regular washing, he first selects the regular washing program on the washing machine, then sets the regular washing program on the dispensing device and starts the dispensing device. After the washing machine is started, the dispensing device calls the regular washing dispensing program, dispenses detergent when the flow sensor detects the first water inflow, does not dispense clothing treatment agent when the flow sensor detects the second water inflow, and dispenses softener when the flow sensor detects the third water inflow. After the third water inflow, the dispensing device ends the dispensing process and enters the standby state.

[0113] In this embodiment, the dispensing device pre-stores a plurality of dispensing programs corresponding to different washing programs of the washing device. When the user uses the dispensing device, the user sets the same washing program on the washing device and the dispensing device simultaneously, and the dispensing device can automatically call the corresponding dispensing program for dispensing. The user does not need to know how to dispense the clothes treatment agent in each water inlet stage of the washing program. The user only needs to select the washing program of the washing device on the dispensing device to achieve the correct dispensing of the clothes treatment agent, which is convenient for the user.

[0114] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
