[0054] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0055] It should be understood that, when used in this application specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or a collection thereof.

[0056] It should also be understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0057] As used in this application specification and the appended claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrase "if determined" or "if detected [the described condition or event]" may be interpreted, depending on the context, as meaning "once determined," "in response to determination," "once detected [the described condition or event]," or "in response to detection [the described condition or event]."

[0058] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0059] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0060] In some specific embodiments, the liquid dispensing method can be used to dispense any detergent. Detergents include, but are not limited to, laundry powder, detergent liquid, etc. The detergent liquid may include a main detergent, or it may include a main detergent and a secondary detergent, the secondary detergent being fabric softener.

[0061] In some embodiments, combined with Figure 1 The washing device includes a first valve 10 and a second valve 20. The first valve can also be referred to as a washing valve. The second valve can also be referred to as a rinsing valve. The washing device also includes a second valve pipe 21, which is connected to the second valve 20. The second valve pipe can also be referred to as a rinsing valve pipe. The washing device also includes a dispensing box 30, which can be used to dispense various detergents. The washing device also includes a water outlet pipe 50, one end of which is connected to the washing drum 40 for introducing detergent mixed with water into the washing drum 40.

[0062] In some embodiments, combined with Figure 2 The washing device also includes a filter rinsing pipe 22, a filter 23, and a washing drum 40. One end of the filter rinsing pipe 22 is connected to the second valve pipe 21, and the other end is connected to the filter 23. The filter 23 is connected to the washing drum 40. The washing device can be a drum washer-dryer combo. Preferably, the washing device can be a drum washer-dryer combo with a filter.

[0063] In a drum washer-dryer combo with a filter, the filter's function is to filter out lint and debris generated during the drying process. The complete washing and drying process is as follows: a) Water enters the washing valve to rinse the detergent (using detergent as an example here; those skilled in the art should understand that this embodiment is also applicable to other types of detergents); b) Water enters the filter to rinse the filter; c) Washing clothes; d) Rinsing; e) Spin-drying; f) Drying; g) Cooling. Typically, at the beginning of the washing and drying process, water enters the washing valve for a period to rinse the detergent, followed by additional water through the rinsing valve, rinsing the filter, and then the water enters the washing drum to reach the washing water level. However, if there is a water outage during the detergent rinsing stage, or if the user forgets to turn on the tap, or if the tap is turned on for too short a time (e.g., turning it on near the end of the detergent rinsing stage), or even if the tap is turned on after the detergent rinsing stage has ended, the detergent may not be able to enter the washing drum, resulting in clothes not being properly cleaned. To avoid this problem, this application proposes a liquid dispensing method that detects the change in liquid level in the washing tub and times the rinsing time of the detergent to prevent the detergent from being spilled.

[0064] Figure 3 This is a schematic flowchart of a liquid dispensing method provided in an embodiment of this application.

[0065] S31, control the first valve to open so that water can rinse the detergent in the dispensing box.

[0066] The control valve 10 opens to flush the detergent in the dispensing box with water, allowing the detergent to mix with the water before entering the washing drum. When the first valve 10 is open, water enters the dispensing box 30 through the valve to flush the detergent, and the water mixes with the detergent in the dispensing box 30. One end of the water outlet pipe 50 is connected to the washing drum 40. The detergent and water in the dispensing box 30 mix and then enter the washing drum 40 through the water outlet pipe 50.

[0067] In one embodiment, the liquid dispensing method further includes:

[0068] Monitor whether the change in liquid level in the washing drum reaches the first change threshold.

[0069] The system can continuously monitor the water level in the washing drum over a period of time using a water level detector. As water continuously enters the drum, the water level rises. The quantity used to measure this change in water level is called the water level change. The unit of measurement for the water level change can be height or volume. If the water level change reaches the first threshold, it indicates that the detergent mixed with water is entering the drum normally, and the detergent will be used to wash clothes. If the water level change does not reach the first threshold, it indicates a low water level, which may indicate insufficient water or insufficient detergent mixed with water entering the drum, or the user may have forgotten to turn on the tap.

[0070] S32, when the liquid level change in the washing drum reaches the first change, the rinsing time of the detergent in the dispensing box is timed.

[0071] If the liquid level change in the washing tub reaches the first change amount, it indicates that the detergent mixed with water is normally flowing into the washing tub. At this time, the rinsing time of the detergent in the dispensing box begins to ensure that the rinsing time of the detergent reaches a certain duration, ensuring that sufficient detergent mixed with water is normally flowing into the washing tub. Sufficient and adequate detergent mixed with water flowing into the washing tub will ensure that the clothes in the washing tub are effectively washed with a sufficient amount of detergent.

[0072] S33, when the detergent rinsing time reaches the first time, control the first valve to close.

[0073] If the rinsing time of the detergent reaches the first time, it indicates that sufficient detergent mixed with water has been normally introduced into the washing drum, at which point the first valve can be closed. The first time can be, for example, 5 seconds to 5 minutes. Preferably, the first time can be, for example, 2 minutes.

[0074] S34 controls the second valve to open so that the liquid level in the washing drum reaches the preset water level. The second valve is opened to allow water to enter the washing drum after rinsing the filter screen.

[0075] After the first valve closes, the second valve can be opened to allow water to flush the filter screen before entering the washing drum. This ensures the filter screen is thoroughly rinsed, reducing lint residue and clogging. When the water level in the washing drum reaches the preset level, it indicates that enough water has flushed the filter screen and entered the drum, and normal washing can begin. The second valve can be closed when the water level in the washing drum reaches the preset level.

[0076] In this embodiment, the first valve is opened to flush the detergent in the dispensing box with water. When the liquid level in the washing tub reaches a first change, the rinsing time of the detergent in the dispensing box is timed. When the rinsing time reaches a first time, the first valve is closed. The second valve is then opened to bring the liquid level in the washing tub to a preset level. The second valve allows water to rinse the filter screen before entering the washing tub. Timing the rinsing time of the detergent in the dispensing box when the liquid level in the washing tub reaches the first change ensures that sufficient detergent mixed with water flows normally into the washing tub, thereby ensuring that clothes are effectively cleaned and washed. Furthermore, by controlling the opening of the second valve to allow water to rinse the filter screen before entering the washing tub, the filter screen is cleaned with water, reducing lint residue and filter clogging.

[0077] Figure 4 This is a schematic flowchart of a liquid dispensing method provided in another embodiment of this application.

[0078] S41 controls the opening of the first valve to flush the detergent in the dispensing box with water.

[0079] S421, when the liquid level change in the washing drum reaches the first change, the rinsing time of the detergent in the dispensing box is timed.

[0080] S43, when the detergent rinsing time reaches the first time, control the first valve to close.

[0081] S44 controls the second valve to open so that the liquid level in the washing drum reaches the preset water level. The second valve is opened to allow water to enter the washing drum after rinsing the filter screen.

[0082] The implementation methods of S41, S421, S43, and S44 above are the same as those of S421, S43, and S44. Figure 3 The implementation methods of the embodiments are similar or nearly identical, and will not be described again here.

[0083] S422, if the change in liquid level in the washing tub does not reach the first change amount, the rinsing time of the detergent is not timed, and the change in liquid level in the washing tub is monitored until the change in liquid level in the washing tub reaches the first change amount.

[0084] If the liquid level change in the washing tub does not reach the first change amount, it indicates that the detergent mixed with water is not being properly introduced into the washing tub. This may be due to the user not turning on the tap or other malfunctions. Since the detergent mixed with water is not being properly introduced into the washing tub, the liquid level change in the washing tub is monitored to ensure it reaches the first change amount, but subsequent steps are not performed until the liquid level change reaches the first change amount. This prevents clothes from being washed due to insufficient detergent, thus avoiding inadequate cleaning. If the user turns on the tap normally at this stage, water will enter the dispensing box 30 through the first valve 10, mix with the detergent in the dispensing box 30, and the detergent mixture will enter the washing tub 40 through the outlet pipe 50. Correspondingly, the liquid level change in the washing tub will reach the first change amount. Subsequent processing at this point ensures sufficient detergent mixed with water is properly introduced into the washing tub, thereby ensuring that clothes are effectively cleaned and washed.

[0085] Figure 5 This is a schematic flowchart of a liquid dispensing method provided in another embodiment of this application.

[0086] S51 controls the opening of the first valve to flush the detergent in the dispensing box with water, monitors whether the change in the liquid level in the washing drum reaches the first change amount, and monitors and times the change.

[0087] Here, a monitoring timer is set up to check whether the change in the liquid level of the washing tub reaches the first change amount. The monitoring timer can constrain the time for monitoring the change in the liquid level of the washing tub. If the monitoring time reaches the second time and the change in the liquid level of the washing tub has not reached the first change amount, necessary alarm detection and / or alarm prompts can be performed by performing alarm detection and / or outputting alarm prompts.

[0088] S521, when the liquid level change in the washing drum reaches the first change, the rinsing time of the detergent in the dispensing box is timed.

[0089] S53, when the detergent rinsing time reaches the first time, control the first valve to close.

[0090] S54 controls the second valve to open so that the liquid level in the washing drum reaches the preset water level. The second valve is opened to allow water to enter the washing drum after rinsing the filter screen.

[0091] The implementation methods of S51, S521, S53, and S54 above are the same as those of... Figure 3 The implementation methods of the embodiments are similar or nearly identical, and will not be described again here.

[0092] S522, if the monitoring time reaches the second time and the change in liquid level in the washing tub does not reach the first change, an alarm detection is performed and / or an alarm prompt is output.

[0093] The second time interval can be set from 2 minutes to 30 minutes. Preferably, the second time interval can be set to 5 minutes. Generally speaking, within the time interval set by the second time interval, the change in the liquid level in the washing tub should reach the first change amount. If the second time interval is reached during the monitoring time and the change in the liquid level in the washing tub does not reach the first change amount, it indicates that there is a malfunction or that the user has not turned on the tap.

[0094] If the monitoring time reaches the second time and the change in the liquid level in the washing drum does not reach the first change, an alarm can be triggered. For example, the water level detector can be checked to determine if it is faulty and repair it.

[0095] If the monitoring time reaches the second time and the change in the liquid level in the washing tub does not reach the first change, an alarm can also be output. For example, an SMS message can be sent to the user's registered mobile phone number, or a notification message can be sent to the user's mobile phone to inform the user of the current status of the washing device, prompt the user to check whether the faucet is turned on properly, or prompt the user to perform other checks.

[0096] Those skilled in the art should understand that the two steps of alarm detection and alarm output can be performed either one or both.

[0097] If the monitoring time reaches the second time interval but the change in liquid level in the washing tub does not reach the first change interval, it indicates a malfunction or that the user has not turned on the tap. By performing alarm detection and / or outputting alarm prompts, the user can be prompted to turn on the tap, or the malfunction can be rectified. This ensures that water enters the dispensing box 30 through the first valve 10, mixes with the detergent in the dispensing box 30, and the detergent mixture enters the washing tub 40 through the outlet pipe 50. Correspondingly, the change in liquid level in the washing tub will reach the first change interval. Subsequent processing at this point ensures that sufficient detergent mixed with water flows normally into the washing tub, thereby ensuring that clothes are effectively cleaned and washed.

[0098] In one embodiment, the alarm detection includes:

[0099] Control the first valve to close, and control the first valve to reopen;

[0100] The output alarm prompts include:

[0101] An alarm message is displayed on the indicator panel of the washing device.

[0102] A potential malfunction of the first valve can be corrected by controlling its closure and reopening. By controlling the closure and reopening of the first valve, the malfunction can be repaired, ensuring that water enters the dispensing box 30 through the first valve 10. The water mixes with the detergent in the dispensing box 30, and the detergent mixture enters the washing drum 40 through the outlet pipe 50. Correspondingly, the liquid level in the washing drum will reach the first change amount. Subsequent processing at this point ensures that sufficient detergent mixed with water flows normally into the washing drum, thereby ensuring that clothes are effectively cleaned and washed.

[0103] An alarm message can be displayed on the washing machine's indicator panel to prompt the user to turn on the water tap or to troubleshoot the problem. This ensures that water enters the detergent dispenser 30 through the first valve 10, mixes with the detergent in the dispenser 30, and then flows into the washing drum 40 through the outlet pipe 50. Consequently, the liquid level in the washing drum will reach the first change threshold. Subsequent processing at this point ensures that sufficient detergent mixed with water flows normally into the washing drum, thereby guaranteeing effective cleaning and washing of the clothes.

[0104] In one embodiment, the amount of liquid level change in the washing tub is determined based on the following steps:

[0105] Before the control valve is opened, the first water level in the washing drum is determined;

[0106] After the first control valve is opened, the second water level in the washing drum is determined;

[0107] The difference between the second water level and the first water level is determined as the change in the liquid level of the washing drum.

[0108] Before the first valve is opened, the water level detector records the first water level L1 in the washing tub. After the first valve is opened, the water level detector records the second water level L2 in the washing tub. The difference between the second water level L2 and the first water level L1 is determined as the change in the liquid level in the washing tub. After the first valve is opened, detergent mixed with water is introduced into the washing tub, causing the second water level L2 to continuously rise, and the difference between the second water level and the first water level to continuously increase, meaning the change in the liquid level in the washing tub continuously increases.

[0109] In this embodiment, a first water level is determined in the washing tub before the first control valve is opened; a second water level is determined after the first control valve is opened; and the difference between the second water level and the first water level is determined as the change in liquid level in the washing tub. By determining the first water level in the washing tub before the first control valve is opened and the second water level after the first control valve is opened using a water level detector, and determining the difference between the second water level and the first water level as the change in liquid level in the washing tub, the change in liquid level in the washing tub can be continuously monitored, and it can be continuously monitored whether there is enough detergent mixed with water to flow normally into the washing tub, thereby ensuring that clothes can be effectively cleaned and washed.

[0110] In one embodiment, the liquid dispensing method further includes:

[0111] If the rinsing time of the detergent has not reached the first time, keep the first valve open until the rinsing time of the detergent reaches the first time.

[0112] By keeping the first valve open, the detergent rinsing time can be ensured to reach the first time, thereby ensuring that enough detergent mixed with water can be properly introduced into the washing drum, and ensuring that clothes can be effectively cleaned and washed.

[0113] In one embodiment, controlling the second valve to open so that the liquid level in the washing tub reaches a preset water level includes:

[0114] The second valve is opened so that water flows through the second valve pipe and the filter flushing pipe to flush the filter screen before entering the washing drum, so that the liquid level in the washing drum reaches the preset water level.

[0115] like Figure 2 As shown, the washing device may further include a second valve pipe 21. The second valve pipe 21 is connected to the second valve 20. The second valve pipe may also be referred to as a rinsing valve pipe. The washing device may further include a filter rinsing pipe 22. One end of the filter rinsing pipe 22 is connected to the second valve pipe 21, and the other end is connected to the filter 23. The filter 23 is connected to the washing drum 40.

[0116] After the second valve is opened, water flows through the second valve pipe 21 and the filter washing pipe 22 to wash the filter screen 23 before entering the washing drum 40.

[0117] This embodiment controls the opening of the second valve so that water flows through the second valve pipe and the filter screen rinsing pipe to rinse the filter screen before entering the washing drum. By controlling the opening of the second valve, water can flow through the second valve pipe and the filter screen rinsing pipe to rinse the filter screen, reducing filter screen lint residue and reducing filter screen clogging.

[0118] Figure 6This is a schematic flowchart of a liquid dispensing method provided in another embodiment of this application.

[0120] S602, before the control first valve is opened, determine the first water level in the washing drum.

[0121] S603, control the first valve to open so that water can rinse the detergent in the dispensing box. Opening the first valve allows the detergent and water in the dispensing box to mix and then flow into the washing drum.

[0122] S604, after the first control valve is opened, determine the second water level in the washing drum.

[0123] S605, the difference between the second water level and the first water level is determined as the change in the liquid level of the washing drum.

[0124] S606, monitor whether the change in the liquid level of the washing drum reaches the first change amount, that is, whether the difference between the second water level L2 and the first water level L1 is greater than the first change amount L0.

[0125] S6061, if the change in liquid level in the washing tub does not reach the first change amount, it is determined to be an abnormal water inlet.

[0130] S610, normal washing.

[0131] This embodiment controls the opening of a first valve to flush the detergent in the dispensing box with water, monitoring whether the change in the liquid level in the washing tub reaches a first change amount. If the change in the liquid level in the washing tub does not reach the first change amount, the rinsing time of the detergent is not timed, but the monitoring of the change in the liquid level in the washing tub continues until the change in the liquid level in the washing tub reaches the first change amount. If the change in the liquid level in the washing tub reaches the first change amount, the rinsing time of the detergent in the dispensing box is timed, and the monitoring of whether the rinsing time of the detergent reaches the first time is continued. If the rinsing time of the detergent does not reach the first time, the first valve remains open until the rinsing time of the detergent reaches the first time. If the rinsing time of the detergent reaches the first time, the first valve is controlled to close. A second valve is controlled to open so that the liquid level in the washing tub reaches a preset water level. The opening of the second valve is used to allow water to enter the washing tub after rinsing the filter screen. By monitoring whether the liquid level change in the washing drum reaches the first change threshold and whether the detergent rinsing time reaches the first set time, sufficient detergent mixed with water can be ensured to flow normally into the washing drum, thereby ensuring that clothes can be effectively cleaned and washed. Furthermore, by controlling the opening of the second valve, water is allowed to rinse the filter screen before entering the washing drum, which cleans the filter screen, reducing lint residue and filter clogging.
