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 have relatively single functions and do not have the processing logic to deal with special situations such as water outages and power outages. When special situations occur, dispensing errors may occur.

[0003] In addition, the automatic dispensing device directly integrated into the washing machine is limited by the size of the washing machine, and the storage capacity of the clothing treatment agent in the automatic dispensing device is small, which requires frequent replenishment by the user and is not convenient to use. To solve the above problems, the prior art proposes an external dispensing device that can be directly connected to the washing machine to realize the automatic dispensing function. For example, Chinese patent application number 201810154483.9 discloses a detergent dispensing device for a washing machine, including a box body, the box body is provided with a baffle, the baffle is arranged horizontally, and the baffle divides the box body into an upper chamber and a lower chamber; a liquid storage box is provided in the upper chamber, and the liquid storage box is provided with a discharge port; the baffle is provided with a through hole, a feed pipe is inserted in the through hole, the feed pipe is arranged in the lower chamber, and the discharge port is connected to the feed pipe; the feed pipe is provided with a flow pump; a water inlet pipe is provided in the lower chamber, the water inlet pipe runs through the lower chamber, and the water inlet pipe is provided with a water flow sensor, a one-way valve, and a solenoid valve in sequence along the direction of water flow, and the water flow sensor, the one-way valve, and the solenoid valve are all arranged in the lower chamber; a discharge pipe is provided in the lower chamber, the discharge pipe runs through the lower chamber, and the water inlet pipe, the feed pipe and the discharge pipe are evenly connected; an opening is provided in the upper chamber, and a cover is provided at the opening.

[0004] However, in the above scheme, the detergent dispensing device can only dispense a single detergent and has a single function. Moreover, since the detergent dispensing device is independent of the washing machine, it cannot directly obtain the working status of the washing machine. Once special conditions such as water outage and power outage occur, it is more likely to make dispensing errors, affecting the washing effect.

[0005] In view of this, 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 device, which can respond accordingly to special conditions such as suspension of the water inlet process and water outage.

[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 entering the washing machine; after the flow sensor detects the start of water entering, the dispensing device dispenses a clothes treatment agent;

[0009] During the delivery process of the delivery device, when the flow sensor detects that the water inflow has stopped, the delivery device pauses the delivery process and determines whether to enter a standby state waiting for user operation based on the length of time the water inflow has stopped.

[0010] Furthermore, after the flow sensor detects that the water inflow stops, if within the first preset time T 1 If water inflow is detected again, the delivery device continues the suspended delivery process;

[0011] If the water inlet stops for a period of time T 1 After that, the flow sensor does not detect the start of water inflow, and the delivery device enters a standby state waiting for user operation.

[0012] Furthermore, the delivery process of the delivery device includes: the flow sensor detects a first preset water inflow volume X 1 When water enters, the delivery device executes the first preset delivery amount S 1 The first delivery step;

[0013] When the delivery process is paused, the delivery device records the water inflow volume X when the delivery process is paused; when the paused delivery process is continued, when the water inflow volume detected by the flow sensor is (X 1 -X), the delivery device executes the first delivery step.

[0014] Furthermore, the delivery process of the delivery device further includes: after the first delivery step is completed, the flow sensor detects a second preset water inflow volume X 2 When water enters, the delivery device executes the second preset delivery amount S 2 The second delivery step;

[0015] When the dispensing process is suspended after the first dispensing step, the dispensing device records the water inflow volume X' from the last dispensing of the clothing treatment agent to the time when the dispensing process is suspended; when the suspended dispensing process is continued, when the water inflow volume detected by the flow sensor is (X 2 -X'), the delivery device performs the second delivery step;

[0016] Among them, X 1 >X 2 , S 1 >S 2 ;

[0017] Preferably, X 1 =nX 2 , S 1 =nS 2 , n is an integer greater than 1.

[0018] Furthermore, after the delivery device is turned on, the second preset delivery amount S is determined according to the received user setting information. 2 After the delivery device enters the standby state, if a start command is received, it waits for the user to set and redefine the second preset delivery amount S 2 ;

[0019] Preferably, the dispensing device receives user setting information to determine the washing program and / or the type of dispensing of the laundry treatment agent, and determines the second preset dispensing amount S according to the washing program and / or the type of dispensing of the laundry treatment agent. 2 ;

[0020] Preferably, the delivery device is an external delivery device independent of the washing equipment;

[0021] More preferably, the external delivery device includes a communication module, the communication module is communicatively connected to the mobile terminal, the mobile terminal receives setting information from the user, and sends the setting information to the external delivery device.

[0022] Furthermore, after the delivery device is turned on, delivery parameters in the delivery process are determined according to the received user setting information;

[0023] After the delivery device enters the standby state, if the delivery device is in the second preset time T 2 If no start command is received within 10 seconds, the suspended delivery process is terminated, and the delivery device is started again to wait for the user to set and re-determine the delivery parameters;

[0024] If the delivery device is within the second preset time T 2 If a start command is received, the suspended delivery process will continue after the flow sensor detects that water has started to enter;

[0025] Preferably, if the delivery device is within the second preset time T 2 When receiving the start command, the dispensing device sends a prompt message to the user whether to continue the previous dispensing process. After receiving the user's confirmation signal, the dispensing device continues the suspended dispensing process after the flow sensor detects that water starts to enter;

[0026] If the delivery device receives a cancellation signal from the user, the suspended delivery process ends and waits for the user to set and redefine delivery parameters;

[0027] Preferably, the delivery device is an external delivery device independent of the washing equipment;

[0028] More preferably, the external delivery device includes a communication module, the communication module is communicatively connected to the mobile terminal, the mobile terminal receives setting information from the user, and sends the setting information to the external delivery device.

[0029] Furthermore, when the flow sensor detects that the water inflow stops, a prompt message is sent to the user to ask whether to end the current delivery process;

[0030] If the delivery device is within the first preset time T 1 If no cancellation signal from the user is received and the flow sensor does not detect the start of water inflow, the delivery device ends the delivery process and enters the standby state.

[0031] Furthermore, when the dispensing device is powered off and shut down during the dispensing process, the dispensing parameters used before the shutdown are obtained after the dispensing device is restarted, and the clothing treatment agent is dispensed according to the dispensing parameters used last time after receiving the start command.

[0032] Furthermore, when the delivery device is powered on again after being powered off, a prompt message is issued asking whether to adopt the previous delivery parameters;

[0033] If a confirmation signal from the user is received, the dispensing device dispenses the laundry treatment agent according to the dispensing parameters used last time after receiving the start instruction; otherwise, the dispensing device waits for the user to set and redetermine the dispensing parameters.

[0034] Furthermore, when the delivery device is powered on again after being powered off, if a shutdown command is received and the device is powered on again, the delivery parameters are redetermined by waiting for the user to set them.

[0035] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0036] The dispensing device of the present invention can control the process of dispensing clothing treatment agent according to the water inlet conditions detected by the flow sensor. The external dispensing device itself can respond to special conditions such as pause of the water inlet process and water outage, suspend the dispensing process, and enter a standby state, which is convenient for users to use.

[0037] The delivery device of the present invention stops when the water inflow is less than the first preset time T 1 When the water inflow is stopped for a long time, the dispensing device can automatically enter the standby state, thus realizing the automatic standby state of the dispensing device after the washing machine stops filling with water or when the water is cut off, which is more intelligent.

[0038] The dispensing device of the present invention intermittently dispenses the clothing treatment agent according to the water intake detected by the flow sensor, and the amount of the clothing treatment agent is more accurately controlled, and it is easier to achieve uniform distribution of the clothing treatment agent in the water, so as to achieve a better washing effect. When the dispensing process is paused, the dispensing device can record the current water intake, and when the paused dispensing process is continued, when the subsequent water intake and the recorded water intake accumulate to reach the first / second preset water intake, the corresponding dispensing step is executed, thereby ensuring the accurate dispensing of the clothing treatment agent.

[0039] After entering the standby state, the delivery device of the present invention continues to wait for a second preset time T 2 The paused dispensing process is then ended, or a prompt message is issued to remind the user when the dispensing process is paused, and the paused dispensing process is ended without the user performing any operation, thereby avoiding the situation where the dispensing process is mistakenly ended due to the long water supply stop time when the user manually pauses the water supply to the washing device.

[0040] The dispensing device of the present invention has a power-off memory function, and can automatically use the previous dispensing parameters to dispense the clothing treatment agent when it is turned on again, without the need for manual settings by the user, which is more convenient for users to use.

[0041] 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

[0047] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0048] 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.

[0049] 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 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.

[0050] The dispensing device of the present invention includes a flow sensor for detecting the amount of water inflow into the washing device. After the flow sensor detects that water inflow has started, the dispensing device dispenses the laundry treatment agent. During the dispensing process of the dispensing device, when the flow sensor detects that water inflow has stopped, the dispensing device pauses the dispensing process and determines whether to enter a standby state for waiting for user operation according to the duration of water inflow stoppage.

[0051] As a preferred embodiment of the present invention, after the flow sensor detects that the water inflow stops, if within the first preset time T 1 If the water inflow is detected again within a certain period of time, the delivery device continues to execute the suspended delivery process. 1 After that, the flow sensor does not detect the start of water inflow, and the delivery device enters a standby state waiting for user operation.

[0052] In the above solution, the delivery device can be integrated into the washing device. When the flow sensor detects that the water inflow stops for a first preset time T, 1 After that, the dispensing device enters the standby state, or the washing machine and the dispensing device enter the standby state together.

[0053] Specifically, when the washing device completes the water inlet process, the washing device continues to run the subsequent steps of the washing program after the water inlet stops, and the dispensing device stops when the water inlet stops for a first preset time T. 1 After that, it enters the standby state. If the water supply stops due to water outage, the first preset time T 1 After that, the washing equipment and the dispensing device enter the standby state together.

[0054] The dispensing device in the present invention can also be an external dispensing device that exists independently of the washing device. In the above scheme, the external dispensing device can control the process of dispensing the clothes treatment agent according to the water inflow condition detected by the flow sensor. Even if there is no communication connection between the external dispensing device and the washing device, the external dispensing device itself can respond to special conditions such as the suspension of the water inflow process and the water outage, suspend the dispensing process, and enter the standby state, which is convenient for users to use.

[0055] Embodiment 1

[0056] 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.

[0057] The delivery device of this embodiment includes a flow sensor for detecting the amount of water entering the washing device, such as Figure 1 As shown, after the flow sensor detects the start of water inflow, the dispensing device starts dispensing the clothing treatment agent.

[0058] During the delivery process of the delivery device, when the flow sensor detects that the water inflow has stopped, the delivery device pauses the delivery process and determines whether to enter a standby state waiting for user operation based on the length of time the water inflow has stopped.

[0059] In the above scheme, the dispensing device controls the process of dispensing the laundry treatment agent according to the water inflow condition detected by the flow sensor, so as to control the start and pause of the dispensing process. The dispensing device itself can respond to special conditions such as the pause of the water inflow process and water outage according to the detected water inflow condition, so as to pause the dispensing process and enter the standby state, which is highly intelligent and convenient for users to use.

[0060] In a further solution of this embodiment, after the flow sensor detects that the water inflow stops, if the flow sensor detects that the water inflow stops within the first preset time T 1 If water inflow is detected again, the delivery device continues the paused delivery process.

[0061] If the water inlet stops for a period of time T 1 After that, the flow sensor does not detect the start of water inflow, and the delivery device enters a standby state waiting for user operation.

[0062] In the above solution, when the water inlet stops for less than the first preset time T 1 When the water inflow stops, the user usually manually stops the water inflow, such as when the user adds clothes to the washing machine or resets the washing water level on the washing machine. When the flow sensor detects the start of water inflow again, the dispensing device continues the paused dispensing process without user operation, and the total amount of clothing treatment agent dispensed is not affected.

[0063] When the water supply stops for a long time, which generally corresponds to the end of the current water supply stage of the washing equipment, or the water supply is cut off, the dispensing device can automatically enter the standby state without the need for user operation, which is more intelligent.

[0064] The first preset time T 1 It can be set as the shortest time interval between two adjacent water inlet stages of the washing machine to avoid the situation where the dosing device judges two different water inlet stages as the same water inlet stage, resulting in incorrect dosing of the clothing treatment agent.

[0065] In this embodiment, the shortest time interval between the end of the washing water inlet phase and the start of the first rinsing water inlet phase of the washing device is 6 minutes, so the first preset time T 1 Set to 6 minutes.

[0066] like Figure 2 As shown, in a further solution of this embodiment, the delivery process of the delivery device includes: the flow sensor detects a first preset water inflow volume X 1 When water enters, the delivery device executes the first preset delivery amount S 1 The first delivery step.

[0067] When the delivery process is paused, the delivery device records the water inflow volume X when the delivery process is paused. When the paused delivery process is continued, when the water inflow volume detected by the flow sensor is (X 1 -X), the delivery device executes the first delivery step.

[0068] Furthermore, the delivery process of the delivery device further includes: after the first delivery step is completed, the flow sensor detects a second preset water inflow volume X 2 When water enters, the delivery device executes the second preset delivery amount S 2 The second delivery step. Among them, X 1 >X 2 , S 1 >S 2 ;

[0069] When the dispensing process is paused after the first dispensing step, the dispensing device records the water inflow volume X' from the last dispensing of the laundry treatment agent to the time when the dispensing process is paused. When the paused dispensing process is continued, when the water inflow volume detected by the flow sensor is (X 2 -X'), the delivery device executes the second delivery step.

[0070] Preferably, the X 1 and S 1 Set to meet: X 1 =nX 2 , S 1 =nS2 . Wherein, n is an integer greater than 1.

[0071] In the above solution, the dispensing device intermittently dispenses the clothing treatment agent according to the water intake detected by the flow sensor, and the dispensing device can accurately control the amount of clothing treatment agent dispensed without obtaining the total water intake of the washing device in advance. At the same time, the clothing treatment agent is dispensed multiple times during the entire water intake process, making it easier for the clothing treatment agent to be evenly distributed in the water, thereby achieving a better washing effect.

[0072] When the dispensing process is paused, the dispensing device can record the current water intake volume. When the paused dispensing process is continued, when the subsequent water intake volume and the recorded water intake volume are accumulated to reach the first / second preset water intake volume, the corresponding first / second dispensing steps are executed. When the water intake process is paused halfway, the amount of clothing treatment agent dispensed can also be accurately controlled.

[0073] The first preset water inflow X 1 The set value is greater than the second preset water inlet X 2 , it can be ensured that when the dispensing device dispenses the clothes treatment agent for the first time, there is already a sufficient amount of water in the washing device, thereby preventing the clothes treatment agent from being directly absorbed by the clothes and unable to be fully dissolved in the water.

[0074] In a further solution of this embodiment, the delivery device is an external delivery device independent of 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 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 provided on the delivery pipeline for delivering the laundry treatment agent into the water inlet pipeline. The flow sensor is provided on the water inlet pipeline.

[0075] When in use, the water inlet end of the water inlet pipe is connected to the external water source, and the water outlet end of the water inlet pipe 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 pipe 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 pipe, so that the clothing treatment agent enters the washing device together with the water in the water inlet pipe.

[0076] The external delivery device has an independent control system, which is electrically connected to the flow sensor and the delivery mechanism. The control system receives the water inlet signal detected by the flow sensor, and then sends corresponding instructions to the delivery mechanism to control the delivery mechanism to deliver clothing treatment agent into the water inlet pipeline.

[0077] The external delivery device has an operation panel for user operation, the operation panel includes a plurality of function buttons, or the operation panel is a touch screen. The user can set the program of the external delivery device through the operation panel, and the operation panel is electrically connected to the control system of the external delivery device to send the user's setting information to the control system.

[0078] Alternatively, the external delivery device includes 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 communication module of the external delivery device. The communication module is electrically connected to the control system of the external delivery device, and sends the user's setting information to the control system.

[0079] After the external delivery device is turned on, the second preset delivery amount S is determined according to the received user setting information. 2 After the external delivery device enters the standby state, if a start command is received, it waits for the user to set and redefine the second preset delivery amount S 2 .

[0080] In a preferred solution of this embodiment, the external delivery device includes at least two independent liquid storage chambers, and different clothing treatment agents are respectively contained in the multiple liquid storage chambers.

[0081] The external dispensing device receives the user setting information to determine the washing program and / or the type of dispensing of the laundry treatment agent, and determines the second preset dispensing amount S according to the washing program and / or the type of dispensing of the laundry treatment agent. 2 .

[0082] Specifically, before the user starts washing clothes, he sets the washing program on the washing device and selects the corresponding washing program and the type of clothes treatment agent he wants to use on the external dispensing device. The control system of the external dispensing device has built-in second preset dispensing amounts S corresponding to different washing programs and clothes treatment agent types. 2 , which can be directly called when applying clothing treatment agent.

[0083] The second preset water inflow X 2 For example, when the conventional washing program is selected, the second preset dosage of concentrated laundry detergent S 2 Set to 1g, the second preset dosage of ordinary laundry detergent S 2 When selecting the washing program for stubborn stains, the second preset dosage of concentrated laundry detergent S 2 Set to 1.5g, the second preset dosage of ordinary laundry detergent S 2 Set to 3g.

[0084] When setting the type of clothing treatment agent, the user can choose to add a single type of clothing treatment agent, or can choose to add multiple types of clothing treatment agents at the same time.

[0085] When the external dispensing device of this embodiment is used, the two ends of the water inlet pipe are connected to the tap water joint and the water inlet valve of the washing device respectively, and the external dispensing device is turned on by the power button. Then the user sets the external dispensing device through the operation panel, selects the washing program corresponding to the washing device, and sets the type of clothing treatment agent dispensing, and then sends a start instruction to the external dispensing device through the start button on the operation panel.

[0086] After the user starts the washing machine, the external dispensing module can control the dispensing process of the laundry treatment agent according to the water inflow detected by the flow sensor, automatically pausing the dispensing process when the water inflow is paused, and automatically continuing the paused dispensing process when the water inflow continues. After the water inflow phase ends, or when the water is cut off, the external dispensing module can automatically enter the standby state after pausing the dispensing process for a certain period of time.

[0087] In the absence of a communication connection between the external dispensing device and the washing equipment, after the external dispensing device is started, the entire dispensing process can be completed without the need for user operation. During the dispensing process, the device can respond accordingly to special conditions such as pause in the water supply process and water outage. It is highly intelligent and convenient for users to use.

[0088] Embodiment 2

[0089] like Figure 3 As shown, this embodiment is a further limitation of the above-mentioned embodiment 1. After the external delivery device is turned on, the delivery parameters in the delivery process are determined according to the received user setting information.

[0090] After the external delivery device enters the standby state, if the external delivery device is in the second preset time T 2 If no start command is received, the suspended delivery process is terminated, and the external delivery device is started again to wait for the user to set and re-determine the delivery parameters.

[0091] If the external delivery device is placed at the second preset time T 2 If a start command is received, the suspended delivery process will continue after the flow sensor detects that water has started to enter.

[0092] In this embodiment, the delivery parameters include a washing program and a type of clothing treatment agent.

[0093] When the user manually pauses the water inlet to the washing machine, the user may not be able to stop the washing machine within the first preset time T due to some special circumstances. 1For example, it takes some time to find the clothes you want to put into the washing machine. In this case, when the user controls the washing machine to continue to fill water, the external dispensing device is still expected to continue the previously paused dispensing process.

[0094] In the above solution, after the external delivery device enters the standby state, it continues to wait for the second preset time T 2 The paused delivery process ends. The user can send a start command to the external delivery device through the operation panel after the external delivery device just enters the standby state to avoid the delivery process ending. When the washing machine continues to fill with water, the external delivery module can continue to execute the paused delivery process, avoiding the situation where the delivery process is mistakenly ended due to the water inflow stop time being too long.

[0095] In the preferred solution of this embodiment, if the external delivery device is set at the second preset time T 2 When the start instruction is received, a prompt message is sent to the user whether to continue the previous delivery process. After receiving the user's confirmation signal, the external delivery device continues the paused delivery process after the flow sensor detects that water starts to enter.

[0096] If the external delivery device receives a cancellation signal from the user, the suspended delivery process ends and waits for the user to set and redefine the delivery parameters.

[0097] In the above scheme, the external dispensing device sends a prompt message to the user after restarting, and determines whether to end the paused dispensing process according to the user's choice, which further ensures that the external dispensing device can correctly dispense the clothing treatment agent according to the user's needs.

[0098] Embodiment 3

[0099] like Figure 4 As shown, this embodiment is a further limitation of the above-mentioned embodiment 1. When the flow sensor detects that the water inflow stops, a prompt message is sent to the user to ask whether to end the current delivery process.

[0100] If the delivery device is within the first preset time T 1 If the user's cancellation signal is not received and the flow sensor does not detect the start of water inflow, the delivery device ends the delivery process and enters the standby state. When the delivery device is started again, it waits for the user to set and re-determine the delivery parameters.

[0101] If the delivery device is within the first preset time T 1 If the user's cancellation signal is received, the timing is stopped and the delivery process remains paused. The flow sensor continues to work. When water inflow is detected, the paused delivery process is continued.

[0102] In this embodiment, the delivery device sends a prompt message to the user while pausing the delivery process. If the delivery process is paused due to the user manually pausing the water intake, the user can perform an operation to cancel the end of this delivery process. 1 Even if the water inlet of the washing machine is turned on, the dispensing process will not be terminated. After the washing machine continues to be filled with water, the dispensing device can still continue to execute the suspended dispensing process.

[0103] In the case where the delivery device is an external delivery device, if the delivery process is paused due to the user manually pausing the water inlet, and the user is also near the external delivery device at this time, the user can operate the external delivery device to cancel the end of this delivery process. This embodiment is similar to the above-mentioned embodiment 2, and also has the effect of preventing the delivery process from being terminated by mistake.

[0104] Embodiment 4

[0105] This embodiment is a further limitation of the above-mentioned embodiment 1, wherein the dispensing device is an external dispensing device. When the external dispensing device is powered off and shut down during the dispensing process, the dispensing parameters used before the shutdown are obtained after the device is turned on again, and the clothing treatment agent is dispensed according to the dispensing parameters used last time after receiving the start command.

[0106] In a further solution of this embodiment, when the external delivery device is powered on again after being powered off, a prompt message is issued asking whether to adopt the previous delivery parameters.

[0107] If a confirmation signal from the user is received, the external dispensing device dispenses the laundry treatment agent according to the dispensing parameters used last time after receiving the start instruction. Otherwise, the external dispensing device waits for the user to set and re-determine the dispensing parameters.

[0108] In another solution of this embodiment, when the external delivery device is powered on again after being powered off, if a shutdown instruction is received and the device is powered on again, the delivery parameters are redetermined by waiting for the user to set them.

[0109] In this embodiment, the external dispensing device has a power-off memory function, and can automatically use the previous dispensing parameters to dispense the laundry treatment agent when the machine is turned on again, without the need for manual settings by the user, which is more convenient for users to use. If the user wants to reset the dispensing parameters, the previous dispensing parameters can be cancelled when the machine is turned on again after power failure, or the dispensing parameters can be reset by turning off the machine and turning it on again, which is simple to operate.

[0110] 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.
