Description

A method for dispensing a laundry treatment agent for a washing machine and a washing machine

Technical field

The present invention belongs to the technical field of washing machines, and specifically relates to a method for dispensing a laundry treatment agent for a washing machine and a washing machine.

Background technique

With the improvement of the automation of washing machines, most washing machines are equipped with a detergent delivery box that can automatically dispense detergent. The detergent delivery box is provided with different accommodation chambers for adding detergent, softener, disinfectant, etc. to clothes. To process reagents, each accommodation chamber is connected to the water inlet pipeline. The detergent, softener, and disinfectant in different accommodation chambers are automatically flushed into the washing bucket through the water inlet pipeline, thereby realizing automatic delivery of detergent.

Since the main component of detergent is anionic surfactant, while the main component of softener is cationic surfactant, they cannot be added at the same time. At the same time, in order to maintain the effect of the softener, the softener is usually added during the last rinse to prevent Adding it too early will cause the softener to be washed out too much and become ineffective. In actual use, detergent and softener are often misplaced, or detergent is misplaced in the softener area, which not only causes a waste of detergent, but also affects the washing and rinsing effects of the washing machine.

The Chinese patent application number 201610767295.4 discloses a method of dispensing washing reagents in a washing machine. The dispensing method can be manually adjusted by the user through the adjustment button provided on the washing machine, or through the dispensing box provided in the distribution box and connected to the controller. The washing reagent detection unit detects reagent information of the washing reagent and adjusts the water inlet timing of the water inlet pipe in the distribution box of the washing machine. Although this application avoids to a certain extent the waste of washing reagents caused by incorrect placement of washing reagents, or the inability to perform normal washing due to serious errors in the placement sequence. However, in this application, an additional adjustment button needs to be set on the washing machine to trigger the operation of adjusting the water inlet timing. The user must manually operate the adjustment button next to the washing machine to complete the operation of adjusting the water inlet timing, which adds more time to the user. There is a certain amount of trouble, and the user operation is relatively cumbersome, and the user experience is not good.

In view of this, the present invention is proposed.

When the laundry treatment agent in the accommodation chamber is accidentally injected, the washing machine can control the water inlet pipeline to inlet water in a water inlet timing different from the preset water inlet timing based on the received user voice command information.

In the method of dispensing the laundry treatment agent for the washing machine provided by this embodiment, the operation of correcting the water inlet timing of the corresponding water inlet pipes of each accommodation chamber can be realized through voice control. The voice control method is more artificially intelligent. , the control is simple and convenient, without the need for manual operation by the user, which improves the user experience, and can also effectively ensure that the accidentally injected clothing treatment agent can be fully utilized, avoiding the waste caused by the accidental injection of clothing treatment agent, or serious errors in the order of injection. A phenomenon that affects the washing effect.

In one embodiment, the washing machine stores a first water inlet timing sequence corresponding to the water inlet pipeline of each accommodation chamber and a second water inlet timing sequence that is different from the first water inlet timing sequence, and the first water inlet timing sequence is The washing machine has a preset water inlet sequence. When the laundry treatment agent is accidentally injected into the accommodation chamber, the washing machine can control the water inlet pipeline to inlet water in a second water inlet sequence according to the received user voice command information. In this embodiment, the washing machine can timely adjust the water inlet timing of the washing machine through voice control, correct the water inlet timing of each chamber in the washing machine distribution box, and ensure the accurate delivery of the laundry treatment agent of the washing machine, thereby ensuring the washing effect of the washing machine. .

Preferably, as shown in Figure 4, the accommodation chamber includes a first accommodation chamber 1 for putting in detergent and a second accommodation chamber 2 for putting in softener. The first accommodation chamber 1 is connected to the first water inlet pipeline through the first interface 3, and the first water inlet pipeline supplies water to flush the detergent in the first accommodation chamber 1 into the washing bucket. The second accommodation chamber 2 is connected to the second water inlet pipeline through the second interface 4, and the second water inlet pipeline supplies water to flush the softener in the second accommodation chamber 2 into the washing bucket. The first water inlet timing is the default preset water inlet timing for the first accommodation chamber 1 to take precedence over the second accommodating chamber 2 , and the second water inlet timing is for the second accommodation chamber 2 Priority is given to the water inlet timing of the first accommodation chamber 1 .

If the user receives relevant voice command information such as "The softener has been put into the softener area", "The softener has been put into the detergent area", the water inlet pipeline will be controlled to perform the water inlet operation in the second water inlet sequence. Within the set T1 time, if no user-related voice command information is received, the water filling operation will be performed according to the first water filling sequence.

Preferably, the T1 is 10-20s. This set time T1 should not be too long to avoid affecting the normal aging of the washing program, nor is it too short. If it is too short, the user may put in the wrong food before he or she can react, and the washing machine will fail. The water filling operation has been performed according to the first water filling sequence, so the user cannot control the water filling sequence of the water inlet pipe through voice commands.

Furthermore, the control unit of the washing machine obtains the corresponding delivery sequence according to the category of the laundry treatment agent fed back by the detection unit, and then obtains the theoretical water inlet timing sequence corresponding to the accommodation chamber, and automatically controls the water inlet pipeline according to the obtained theory. The water inlet sequence executes water inlet or regulates the water inlet sequence of the water inlet pipeline according to the received user voice command information. In this embodiment, the water inlet timing of the washing machine is automatically determined and combined with the user's voice control instructions to control the water inlet timing of the delivery pipeline. The water inlet timing can be adjusted in a timely and efficient manner, ensuring the washing effect of the washing machine, and also satisfying customers. meet the personalized needs of the washing machine, while improving the intelligence of the washing machine and improving the user experience.

S1. The detection unit detects the reagent information of the clothing treatment agent placed in each storage chamber, and obtains the category of the clothing treatment agent placed in each storage chamber;

S2. Determine whether the type of laundry treatment agent put into each accommodation chamber is consistent with the preset category of laundry treatment agent in each accommodation chamber. If so, perform the water inlet operation according to the preset water inlet sequence; if not, perform the water inlet operation. Step S3;

S3. The washing machine obtains the theoretical water inlet timing sequence of the corresponding water inlet pipeline of each accommodation chamber based on the detected clothing treatment agent category, and performs the water inlet operation according to the theoretical water inlet timing sequence;

Or, analyze the received voice command information, and control the washing machine to perform the water filling operation according to the preset water filling timing sequence or the theoretical water filling timing sequence according to the analysis results.

Further, the step S3 also includes: when it is determined that the type of laundry treatment agent injected into each accommodation chamber is inconsistent with the category of laundry treatment agent preset in each accommodation chamber, sending a prompt to the user to confirm whether the injection was made by mistake. information and wait for instructions;

If a voice command message is received from the user confirming that the water has been thrown in by mistake, the water inlet pipeline will be controlled to perform the water filling operation according to the theoretical water filling sequence; if the voice command message from the user is not mistakenly thrown in, the water inlet pipeline will be controlled to preset the water filling sequence. Perform water inlet operation. This prompt method allows users to confirm whether they have mistakenly poured the water in, effectively avoiding misjudgments in the washing machine, which would lead to deviations in the water inlet timing of the water inlet pipeline and affect the normal washing effect.

Further, the step S3 also includes: if the washing machine does not receive the user's voice command information within the T2 time after sending a prompt message to the user to confirm whether it was accidentally thrown, then controlling the water inlet pipeline to perform the operation according to the theoretical water inlet sequence. water operation.

Preferably, the T2 is 5-15s. 5-15 s after the controller of the washing machine sends a prompt message to the user to confirm whether it is accidentally thrown, if it does not receive the user's voice command message, it controls the water inlet pipeline to perform the water inlet operation according to the theoretical water inlet sequence to avoid affecting the washing machine. normal washing time.

In this embodiment, the type of laundry treatment agent corresponds to the water inlet timing sequence, and the corresponding relationship is stored in the controller of the washing machine. Specifically, the clothing treatment reagent detection unit detects reagent information corresponding to the clothing treatment agent in the corresponding accommodation chamber, and obtains the category of the clothing treatment agent and the corresponding delivery sequence based on the detected reagent information, and according to the clothing treatment agent The order in which the agent is placed determines the theoretical water inlet timing of the corresponding accommodation chamber, and the user can be prompted through voice or lighting, etc., and the water inlet timing of the water inlet pipeline is controlled based on the user's voice command information. The delivery method provided by this embodiment realizes the intelligent detection of the laundry treatment agent in the distribution box, further accurately controls the delivery sequence of the laundry treatment agent, and intelligently avoids the user from not placing the washing reagent into the set accommodation chamber. As a result, the expected washing effect cannot be achieved.

Further, the reagent information includes one or any combination of surfactant information, viscosity information, weight information, and pH information; the reagent information includes surfactant information and weight information.

Specifically, in the delivery method, one or any combination of surfactant information, viscosity information, weight information, and pH information in the clothing treatment agent is detected, and the surfactant information, viscosity information, weight information, and The pH information determines the category of the laundry treatment agent and the order in which it is put in. Then the water inlet sequence of each chamber is determined based on the order in which the laundry treatment agent is put in. The controller of the washing machine controls the corresponding water inlet pipeline according to the order of the laundry treatment agent. Perform the water inlet operation in the order of delivery. For example, the detection unit is an ion detection unit, and based on the fact that the main component of the laundry treatment agent is an anionic surfactant and the main component of the softener is a cationic surfactant, it only needs to detect the ions in the laundry treatment agent. status, it is concluded that the detected clothing treatment agent is detergent or softener.

Further, the control module of the washing machine can control the water inlet pipeline to inlet water in a water inlet timing sequence that is different from the preset water inlet timing sequence based on the received voice command information sent by the voice module of the machine or the smart terminal.

Embodiment 2

As shown in Figures 5 to 13, this embodiment is a further improved solution based on Embodiment 1. The washing machine of this embodiment includes a distribution box with at least two accommodation chambers, and the washing machine has an openable/ In the closed water channel flip mode, the washing machine stores the first water inlet timing sequence corresponding to the water inlet pipeline of each accommodation chamber and the second water inlet timing sequence that is different from the first water inlet timing sequence.

When the water channel flip mode is turned off, the current washing program is controlled to perform the water inlet operation according to the first water inlet sequence.

When the water channel flip mode is turned on, the washing machine determines whether the storage amount of the laundry treatment agent in the distribution box meets the delivery requirements, and controls whether the current washing program performs the water inlet operation according to the second water inlet sequence based on the judgment result.

In this embodiment, the distribution box having two accommodation chambers is taken as an example for description.

In this embodiment, the dispensing box of the washing machine has two accommodation chambers, which are a first accommodation chamber for putting in detergent and a second accommodation chamber for putting in softener.

The washing machine stores different first water inlet timing and second water inlet timing. The first water inlet sequence is that water enters the first water inlet pipe when washing starts, and water enters the second water inlet pipe during the last rinse. The second water inlet timing is opposite to the first water inlet timing, that is, the second water inlet pipeline is inlet when washing starts, and the first water inlet pipeline is inlet during the last rinse. Therefore, when the detergent and softener are put in the correct position, the washing machine should perform the water filling operation according to the first water filling sequence, otherwise it needs to perform the water filling operation according to the second water filling sequence.

The washing machine in this embodiment has a water channel flip mode that can be turned on/off. The user can adjust the water inlet timing sequence executed when the washing machine is running by turning on/off the water channel flip mode. The washing machine is provided with a knob-type selection terminal for selecting different washing modes. As shown in Figure 5, the knob-type selection terminal is provided with a waterway flip switch 5. The user turns the knob to position 5 of the waterway flip switch to turn on the waterway flipping mode. Or, as shown in Figure 6, the washing machine is provided with a control panel. The user operates the washing machine through buttons on the control panel. A waterway flip switch 5 is provided on the control panel. The user turns on/off the waterway flipping mode by touching the waterway flip switch 5.

In another solution of this embodiment, the washing machine further includes a mobile terminal that is communicated with the local terminal. As shown in Figures 6 and 7, a waterway flip switch 5 is provided on the operation interface of the mobile terminal. The user can control the turning on/off of the waterway flipping mode through the operation of the mobile terminal.

In this embodiment, when the detergent and softener are placed in the correct position, the user can turn off the water channel flip mode. At this time, the washing machine controls the current washing program to perform the water inlet operation according to the first water inlet sequence.

When the user realizes that the detergent and softener are put in reversely, the water channel flip mode can be turned on, so that the washing machine can perform the water filling operation according to the second water filling sequence to avoid errors in the washing process.

In this embodiment, the waterway reversal mode can be automatically turned off after the current washing process is completed.

Alternatively, the water reversal mode can be kept on for multiple consecutive washing cycles.

Specifically, when the washing machine receives a signal from the user to turn on the water channel flip mode, it controls the water channel flip mode to be turned on for this washing program and the following N-1 washing programs, and automatically turns off the water channel flip mode during the Nth subsequent washing program. Perform the water filling operation according to the first water filling sequence, where N≥2.

Or, when the washing machine receives a signal from the user to turn on the water channel flip mode, it will always keep the water channel flip mode on while the washing machine continues to be powered on; when the washing machine is powered off and powered on again, it will automatically turn off the water channel flip mode, and follow the first The water filling operation is performed in the water filling timing sequence.

When the laundry treatment agent injected by the user at one time can support multiple washing programs, the water channel flipping mode remains on during multiple consecutive washing programs. There is no need for the user to turn on the water channel flipping mode before starting the washing program each time, making the operation more convenient.

In this embodiment, when the water channel flip mode is turned on, the washing machine determines the amount of laundry treatment agent required for this washing process before entering the water, and then determines whether the storage amount of clothing treatment agent in the distribution box meets the delivery requirement. According to the judgment result Control whether this washing program performs water filling operation according to the second water filling sequence.

Specifically, when the washing machine determines that the storage amount of the laundry treatment agent meets the dispensing requirement, the washing machine is controlled to perform the water filling operation according to the second water filling sequence.

When the washing machine determines that the storage amount of the laundry treatment agent does not meet the demand, it will send a prompt message to the user to replenish the laundry treatment agent. After receiving a signal from the user that the laundry treatment agent has been replenished, it will re-determine the water inlet sequence to control the washing machine to perform the water inlet operation.

In view of the situation where the water circuit flip mode is turned on and remains turned on during multiple consecutive washing programs, the washing machine determines the storage amount of the clothing treatment agent before entering the water. When the storage capacity meets the dispensing requirement, it means that the detergent and softener that was mistakenly dispensed previously have not been used up, and the water inlet operation still needs to be performed according to the second water inlet sequence. When the storage capacity does not meet the dispensing demand, it means that the laundry treatment agent in the distribution box has been used up and needs to be replenished by the user. At this time, the user may replenish the laundry treatment agent in the correct position, or may still replenish it in the opposite way to the correct position. The washing machine needs to re-determine the water supply sequence after the user completes the replenishment, so as to ensure that the washing process proceeds correctly.

In one solution of this embodiment, after receiving a signal from the user that the laundry treatment agent has been replenished, the washing machine automatically turns off the water channel flip mode, and controls the washing machine to perform the water filling operation according to the first water filling sequence.

The above solution is designed to prevent users from accidentally dosing the laundry treatment agent. When all the accidentally added laundry treatment agents have been added, detergent and softener will be placed in the correct position when the user adds the laundry treatment agent again. At this time, the washing machine automatically turns off the water channel flip mode, which can prevent the user from forgetting to turn off the water channel flip mode, and the washing machine does not restore the first water inlet sequence, causing errors in the washing process.

In another solution of this embodiment, the washing machine further includes a detection unit for detecting the type of laundry treatment agent in each accommodation cavity, and the washing machine stores a correspondence between the type of laundry treatment agent and the order in which the laundry treatment agent is put.

The detection of clothing treatment agent categories can be achieved through the detection of anions and cations. When it is detected that the cationic surfactant is in the accommodation chamber, the accommodation chamber contains softener; when it is detected that the anionic surfactant is in the accommodation chamber, then the accommodation chamber contains detergent. The dispensing box of the washing machine may also include more holding chambers so that more categories of laundry treatments can be added. When it is detected that the neutral ionic surfactant is present in the accommodation chamber, other types of clothing treatment agents, such as disinfectants, are present in the accommodation chamber.

After receiving a signal from the user that the laundry treatment agent has been replenished, the washing machine controls the washing machine to detect the types of clothing treatment agents in each accommodation chamber, and determines the corresponding delivery sequence based on the detected categories, and then determines the theoretical water inlet of the corresponding accommodation chamber. Timing sequence, perform the water filling operation according to the theoretical water filling timing sequence.

In the above solution, after the user replenishes the laundry treatment agent, the washing machine detects the type of laundry treatment agent in each accommodation chamber through the detection unit, thereby obtaining the theoretical water inlet timing sequence and executing it. In this way, the washing machine can automatically determine the correct water inlet timing without user operation. It also avoids user memory errors that cause the set water inlet timing to be inconsistent with the actual location of the laundry treatment agent, leading to errors in the laundry process.

In yet another solution of this embodiment, as shown in FIG. 9 , after receiving a signal from the user that the laundry treatment agent has been replenished, the washing machine sends a prompt message to the user to turn off the waterway flipping mode, and waits for the user to choose whether to turn off the waterway flipping mode.

After receiving the signal to turn off the water channel flip mode, the washing machine performs the water filling operation according to the first water filling sequence. After receiving the signal of not turning off the water channel flip mode, the washing machine performs the water filling operation according to the second water filling sequence.

In the above solution, for the case where the distribution box only has two accommodation chambers, there are only two ways of adding the laundry treatment agent, corresponding to the first water inlet timing and the second water inlet timing. When the user refills the laundry treatment agent, he may put it in the correct position, or he may still put it in the opposite position. The washing machine prompts the user to reselect the water supply sequence after the user completes the delivery of the laundry treatment agent. The user manually chooses whether to turn off the water channel flip mode based on the delivery situation, which reduces the probability of errors in the laundry process.

In this embodiment, the dispensing box of the washing machine may also include more accommodation chambers, so that more types of laundry treatment agents can be placed. As the types of laundry treatment agents that can be placed increase, the possible locations of laundry treatment agents and the corresponding water inlet timing also increase.

The first water inlet sequence of the washing machine corresponds to the default placement position of the laundry treatment agent. The washing machine also has the function of allowing the user to customize the placement location of commonly used laundry treatment agents. The washing machine determines the placement location corresponding to the placement location set by the user and the corresponding relationship between the category and delivery order of the laundry treatment agents. The corresponding water inlet timing is stored as the second water inlet timing.

Users can operate on the local side of the washing machine to set the location of the laundry treatment agent, or they can also set it through the mobile terminal connected to the local side.

As shown in Figure 10, the mobile end of the washing machine is provided with a delivery position setting switch 6 for turning on the setting of the laundry treatment agent delivery position. The operation interface of the mobile terminal of the washing machine in this embodiment for setting the clothing treatment agent delivery position is shown in Figure 11. The washing machine includes a distribution box with three accommodation chambers, namely a first accommodation chamber, a second accommodation chamber, and a distribution box. The three accommodation chambers correspond to the first area A, the second area B and the third area C on the operation interface. At the same time, the three accommodation chambers are respectively connected with the corresponding first water inlet pipeline, the second water inlet pipeline and the third water inlet pipeline.

As shown in Figure 11, it is a setting situation of a clothing treatment agent delivery position. At this time, the first accommodation chamber corresponding to the first area A is placed with detergent, and the second accommodation chamber corresponding to the second area B is placed with disinfection. The softener is placed in the third accommodation chamber corresponding to the third area C. Correspondingly, the second water inlet sequence stored in the washing machine is that the second water inlet pipe enters water first, the first water inlet pipe enters water when starting washing, and the third water inlet pipe enters water during the last rinse.

In response to the above situation, when the washing machine turns on the water channel flip mode and detects that the laundry treatment agent does not meet the delivery requirements, the user is reminded to replenish the laundry treatment agent. When the user replenishes the laundry treatment agent, the laundry treatment agent may be placed according to the default placement location, or the laundry treatment agent may be placed according to the set placement location, or there may be a placement situation different from the above two situations.

In order to ensure that the subsequent washing process is carried out correctly, in a further solution of this embodiment, the washing machine sends a prompt message to the user to turn off the water channel flip mode, and after receiving a signal not to turn off the water channel flip mode, the washing machine is controlled to perform the following steps:

1) The detection unit detects the categories of clothing treatment agents in each accommodation chamber, and determines the corresponding delivery sequence based on the detected categories, and then determines the theoretical water inlet timing sequence of the corresponding accommodation chamber;

2) Determine whether the theoretical water inlet timing is consistent with the second water inlet timing. If the judgment result is yes, the washing machine is controlled to perform the water inlet operation according to the second water inlet timing. If the judgment result is no, the washing machine is controlled to perform the water inlet operation according to the theoretical water inlet timing sequence. Perform water inlet operation.

In the above solution, after the user replenishes the clothing treatment agent, the washing machine detects the type of clothing treatment agent in each accommodation chamber through the detection unit, thereby obtaining the theoretical water inlet timing. When the theoretical water inlet timing is consistent with the second water inlet timing, The water inlet operation is performed according to the second water inlet timing, and when the two are inconsistent, the water inlet operation is performed according to the theoretical water inlet timing, ensuring that the executed water inlet timing is consistent with the actual situation of the clothing treatment agent placement location.

In another solution of this embodiment, as shown in Figure 12, when it is determined in step 2) that the theoretical water inlet timing is inconsistent with the second water inlet timing, step 3) is executed: determine whether the number of detections by the detection unit is greater than the preset Number of times N1, if the judgment result is yes, the washing machine will sound an alarm, if the judgment result is no, then return to step 1).

In the above solution, when the theoretical water inlet timing is inconsistent with the second water inlet timing, the washing machine control and detection device performs multiple repeated detections to avoid misjudgment in a single detection. When multiple detections are inconsistent, the washing machine will alert the user through an alarm. The user can independently check the placement of the clothing treatment agent and set the water inlet sequence for the subsequent washing program to ensure that the washing machine can process the clothes according to the instructions when running the washing program. The water inlet operation is performed according to the water inlet timing corresponding to the location of the agent.

In a further solution of this embodiment, as shown in Figure 13, when it is determined in step 2) that the theoretical water inlet timing is inconsistent with the second water inlet timing, step a) is performed before step 3): determine the value determined by this detection. Is the theoretical water inlet timing sequence consistent with the theoretical water inlet timing sequence determined by the previous N2 tests? If the judgment result is yes, control the washing machine to perform the water inlet operation according to the theoretical water inlet timing sequence. If the judgment result is no, perform Step 3). Among them, the setting of N2 satisfies N2<N1.

In the above solution, when the theoretical water inlet timing sequence determined by the detection unit of the washing machine is the same several times in a row, the water inlet operation is automatically performed according to the theoretical water inlet timing sequence. When the theoretical water inlet sequence determined by the test is the same for many times, the possibility of misjudgment by the detection unit is very low. At this time, the washing machine automatically runs the washing program and performs the water inlet operation according to the theoretical water inlet sequence, eliminating the need for the user to manually The operating steps of the washing machine are highly automated.

The implementations in the above embodiments can be further combined or replaced, and the embodiments are only to describe the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, there are many technical problems in this field. Various changes and improvements made by professional and technical personnel to the technical solution of the present invention all belong to the protection scope of the present invention.
