Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

Hereinafter, a water filling control method, apparatus and laundry treating apparatus according to embodiments of the present application will be described with reference to the accompanying drawings.

Fig. 1 is a schematic flow chart of a water injection control method according to an embodiment of the present application.

The water injection control method of the embodiment of the application is applied to a clothes treatment device, and the clothes treatment device comprises: a first water inlet valve for filling water into the water tub without passing through the microbubble generator, and a second water inlet valve for filling water into the water tub with passing through the microbubble generator.

In the embodiment of the present application, the micro bubble generator is configured to produce micro bubble water and introduce the micro bubble water into the water tub, and the micro bubble water may be used to participate in a washing process of the laundry, or the micro bubble water may be used to participate in a rinsing process of the laundry, or the micro bubble water may also participate in other processes of the laundry treatment apparatus, which require the micro bubble water, such as cleaning a sealing ring, cleaning the dirt, and the like, without limitation.

The laundry treatment device may be a drum washing machine, a pulsator washing machine, a washing and drying machine, or the laundry treatment device may be other types of devices, which is not limited herein. The tub is a tub for treating laundry, for example, the tub may be an inner tub of a drum washing machine, or the tub may be a tub of a pulsator washing machine, or the like.

As shown in fig. 1, the water injection control method includes the following steps:

step 101, opening a first water inlet valve to inject water to reach a first water level.

In the embodiment of the present application, the first water level is preset, and the first water level may be a heating water level, for example.

The water filling control method of the embodiment of the application can be applied to a clothes treatment device which is not automatically filled with detergent, for example, a user can manually pour the detergent into a water drum when washing clothes.

In the embodiment of the present application, after the first water inlet valve is opened, the water flow does not flow through the micro-bubble generator, and the water is directly injected into the water tub, and after the second water inlet valve is opened, the water flow flows through the micro-bubble generator and is injected into the water tub. The water amount flowing into the water containing barrel in unit time after the first water inlet valve is opened is higher than the water amount flowing into the micro-bubble generator in unit time after the second water inlet valve is opened.

It can be understood that, since the water inflow amount of the micro bubble generator is much smaller than the water amount flowing into the water tub after the first water inlet valve is opened, if the second water inlet valve is controlled to be opened to inject the micro bubble water into the water tub during water injection in order to improve the washing effect of the laundry, the water injection time is long, and the operation time of the laundry treatment apparatus is too long. If the first water inlet valve is always controlled to open in order to improve the water injection efficiency during water injection, the content of air bubbles in the water tank is low, and the washing effect of the clothes cannot be ensured.

Therefore, in the present application, in order to improve the water filling efficiency and simultaneously ensure the washing effect of the laundry, when the water is filled into the water tub, only the first water inlet valve may be controlled to be opened at first, so that the water content in the water tub reaches the first water level quickly, thereby enabling other components of the laundry treatment apparatus to work normally, for example, reaching the first water level, such as a heating water level, enabling the heating unit to heat the wash water in the water tub, and improving the operation efficiency of the laundry treatment apparatus.

The first water level can be measured through a sensor, the sensor can collect water level frequency, and whether the water containing amount in the water containing barrel reaches the first water level or not is determined according to the water level frequency.

And 102, controlling at least one of the first water inlet valve and the second water inlet valve to continuously inject water to reach a second water level according to whether the water injection time length of the first water inlet valve is longer than a set time length.

In the embodiment of the present application, the set time period is preset, for example, may be preset for a built-in program of the laundry treatment device, or may also be set by a user, which is not limited thereto. For example, the set time period may be 20 seconds(s). The second water level is preset, and may be a second wash water level, for example.

It can be understood that, when the water filling control method is applied to a laundry treatment apparatus in which detergent is not automatically dispensed, after a user pours detergent (or laundry detergent, washing powder, softener, etc.) into a water tub, the detergent is stacked at one place, and in order to facilitate sufficient dissolution of the detergent, the first water inlet valve may be controlled in advance to be opened for a set time period, so that the detergent is dispersed, i.e., flushed, and thus sufficient dissolution of the detergent is facilitated.

Therefore, in the embodiment of the present application, it may be determined whether the water filling duration of the first water inlet valve is greater than or equal to the set duration, if so, at least one of the first water inlet valve and the second water inlet valve is controlled to continue to fill water to the second water level according to the executed washing stage, and if not, the first water inlet valve is controlled to continue to fill water to enable the water filling duration to reach the set duration.

Specifically, when the washing phase is a washing process, if the water filling duration of the washing process is greater than or equal to the set duration, in order to improve the washing effect of the laundry, the first water inlet valve may be controlled to be closed, and the second water inlet valve may be opened to continue to fill water to a second water level, so as to improve the content of micro bubbles in the water tub. If the water injection time length in the washing process is less than the set time length, in order to flush the detergent (such as washing powder and laundry detergent) so as to facilitate the full dissolution of the detergent, the first water inlet valve can be controlled to be closed in a delayed mode, namely the first water inlet valve is controlled to be opened continuously, the first water inlet valve is closed until the water injection time length of the first water inlet valve is equal to the set time length, and the second water inlet valve is opened to continuously inject water to reach a second water level. Therefore, the detergent can be flushed away while the water injection efficiency is ensured, the detergent can be dissolved sufficiently, meanwhile, the content of microbubbles in washing water in the water containing barrel can be ensured, the detergent can be accelerated to be differentiated into smaller parts through the explosion energy of the microbubbles, the sufficient dissolution of the detergent is promoted, and when stains on clothes are stubborn, the stains are difficult to remove only by the dissolution of the detergent or by the friction between the clothes, and the removal capacity of the stains on the clothes can be enhanced by the explosion energy of the microbubbles, so that the washing effect of the clothes is ensured.

When the washing stage is rinsing, if the water filling duration of the rinsing is greater than or equal to the set duration, the second water inlet valve may be controlled to open until the water filling reaches the second water level in order to increase the content of micro bubbles in the water tub and thus ensure the washing effect. If the water injection time length in the rinsing process is shorter than the set time length, in order to improve the water injection efficiency and simultaneously, in order to realize the flushing of the detergent (such as a softener) so as to be convenient for the full dissolution of the detergent, the first water inlet valve can be controlled to continuously inject water to ensure that the water injection time length reaches the set time length, and then the second water inlet valve is controlled to be opened until the water injection time length reaches a second water level. From this, when guaranteeing water injection efficiency, can realize breaking the detergent to the detergent of being convenient for fully dissolves, simultaneously, can also promote the content of microbubble in the water bucket, the detergent that is infected with on can making the clothing through the blasting energy of microbubble dissolves in aqueous as early as possible, avoids the clothing to remain the detergent. In addition, the washing water contains a large amount of micro-bubbles, so that the using amount of the detergent can be reduced, and the residual detergent on the clothes is further reduced.

In the above embodiment, when the water filling time period in the rinsing process is longer than or equal to the set time period, the first water inlet valve and the second water inlet valve are simultaneously controlled to open, and water is filled into the water tub. The reason is that the operation time of the laundry treating apparatus is limited, and the dirt in the laundry is substantially removed, and at this time, only a small amount of micro bubbles are needed to remove the detergent remaining on the laundry.

The technical scheme in the embodiment of the application at least has the following technical effects or advantages:

and controlling at least one of the first water inlet valve and the second water inlet valve to continuously inject water to reach a second water level according to whether the water injection time of the first water inlet valve is longer than a set time. Therefore, the detergent can be flushed away while the water injection efficiency is ensured, the detergent can be dissolved sufficiently, meanwhile, the content of microbubbles in washing water in the water containing barrel can be ensured, the detergent can be accelerated to be differentiated into smaller parts through the explosion energy of the microbubbles, the sufficient dissolution of the detergent is promoted, and when stains on clothes are stubborn, the stains are difficult to remove only by the dissolution of the detergent or by the friction between the clothes, and the removal capacity of the stains on the clothes can be enhanced by the explosion energy of the microbubbles, so that the washing effect of the clothes is ensured. In addition, the detergent stained on the clothes can be dissolved in water as soon as possible by the explosion energy of the micro-bubbles, so that the detergent is prevented from remaining on the clothes. In addition, the washing water contains a large amount of micro-bubbles, so that the using amount of the detergent can be reduced, and the detergent remained on the clothes is further reduced.

It should be noted that, in practical application, in the process of opening the second water inlet valve for water injection, if the second water inlet valve fails, the washing program will give an alarm, and at this time, the washing program cannot be finished. Therefore, as a possible implementation manner of the embodiment of the application, the water level frequency variation can be detected in real time or periodically through the sensor, whether the water level frequency variation is lower than the preset threshold value or not is judged, and if so, the first water inlet valve is controlled to be opened, so that the situation that the washing program is alarmed and cannot be operated to finish after the second water inlet valve is failed is prevented, and therefore the normal washing of the clothes treatment device is ensured, and the normal operation of the washing program is ensured to finish. The water level frequency variation is preset, and may be 30Hz, for example.

For example, the sensor may detect the water level frequency once every one minute, obtain the water level frequency variation by subtracting the water level frequencies of the two adjacent times, and then determine whether the water level frequency variation is lower than a preset threshold, for example, lower than 30Hz, if so, open the first water inlet valve, so as to prevent the situation that the operation cannot be finished due to the alarm of the washing program after the second water inlet valve fails.

As a possible implementation manner, when the washing stage is a washing process or a rinsing process, the motor can be controlled to drive the drum to rotate, that is, the drum can be controlled to rotate while water is injected, so as to improve the cleaning effect. For example, the motor may be controlled to rotate the drum before the water is filled to the first water level, and/or the motor may be controlled to rotate the drum after the water is filled to the first water level and before the water is filled to the second water level, and/or the motor may be controlled to rotate the drum after the water is filled to the second water level, which is not limited in this respect. In addition, when water is injected, the rotary drum is controlled to rotate, so that the clothes can fully absorb water, and the washing effect of the clothes can be improved when the clothes are washed.

As a possible implementation manner, after washing for a period of time, water is injected again to the set water level of the panel, and under the condition that the default water level is automatic, a third water level, such as a third water level for washing, is generally entered, at this time, the first water inlet valve and the second water inlet valve may be controlled to open, and water is continuously injected to the third water level. Specifically, after water is injected to the second water level, whether the final target water level is reached or not can be judged, if yes, the water injection is stopped, and if not, the first water inlet valve and the second water inlet valve are controlled to be opened, and the water is continuously injected to the final target water level, which is recorded as a third water level in the embodiment of the present application.

As a possible implementation mode, the washing is started after the water injection reaches the second water level, at the moment, in the washing process, because the clothes absorb water, the water level can be reduced, the water containing barrel needs to be replenished, and the rotary drum does not rotate during water replenishing so as to ensure the stability of water level detection.

Specifically, at least one of the first and second water inlet valves may be controlled to be opened for water replenishment according to the water inlet valve opened by the last water injection. For example, when the inlet valve that was opened by the last water injection is the first inlet valve, the first inlet valve and the second inlet valve may be controlled to be opened simultaneously to replenish water, and when the inlet valve that was opened by the last water injection is the second inlet valve, the second inlet valve may be continuously controlled to be opened to replenish water.

As an example, when the user washes laundry, a washing program may be initiated.

1. And if the water level is set to be automatic, starting a drying and weighing process, determining a target water level according to the weight of the drying, and if the water level is not set to be automatic, skipping the weighing step.

2. After weighing is finished, in order to flush the detergent, the first water inlet valve and the third water inlet valve (spraying valve) can be opened for water injection for 15 seconds, and if the third water inlet valve is not arranged, only the first water inlet valve is opened for water injection.

3. When water is filled for the first time, the first grade of washing can be used as a target water level. In this water filling step, water may be filled into the tub by opening only the first water inlet valve before the first water level (e.g., the heating water level) is reached. When the water is filled to the first water level and the filling time of the first water inlet valve exceeds a set time (for example, 20 seconds), the first water inlet valve is closed, and the second water inlet valve is opened to reach the target water level.

4. And after water is fed, washing is started, the water level is reduced due to water absorption of clothes, water needs to be supplemented, and when water is supplemented, the second water inlet valve can be opened for water injection.

5. When the washing is carried out for a period of time, water is injected to the panel again to set the water level, and the water level of the third gear of washing can be generally entered under the condition that the default water level is automatic. In the water injection process, only the second water inlet valve is opened for water injection before reaching the second-gear washing water level, and the first water inlet valve is opened after reaching the second-gear washing water level to inject water to the third-gear washing water level. It should be noted that if the target water level is adjusted to the wash first range water level, this step is not performed, and if the target water level is adjusted to the wash second range water level, the second water inlet valve is opened for filling the water during the entire filling process.

6. And if water is replenished, controlling at least one of the first water inlet valve and the second water inlet valve to be opened according to the opened water inlet valve of the latest water filling so as to replenish water, for example, when the opened water inlet valve of the latest water filling is the first water inlet valve, controlling the first water inlet valve and the second water inlet valve to be opened simultaneously so as to replenish water, and when the opened water inlet valve of the latest water filling is the second water inlet valve, controlling the second water inlet valve to be opened continuously so as to replenish water.

As an example, referring to fig. 2, when water is filled, it may be determined whether the microbubble generation function is turned on, if not, water is normally filled by turning on the first water filling valve to fill the water tub, and if so, it is determined whether the water is filled to the first water level by turning on the first water filling valve and the water filling time of the first water inlet valve is greater than or equal to a set time.

If the time length is more than or equal to the set time length, judging whether the washing stage is a washing process, if so, independently controlling the second water inlet valve to inject water, judging whether the water injection level reaches the second water level, if so, controlling the first water inlet valve and the second water inlet valve to open, and continuously injecting water to the third water level.

And if the rinsing process is carried out, controlling the first water inlet valve and the second water inlet valve to be opened, and continuously injecting water. And judging whether the water injection level reaches the target level, if so, ending the water injection.

As an example, referring to fig. 3, fig. 3 is a schematic structural diagram of a microbubble generator according to a third embodiment of the present application. Wherein, the microbubble generator 100 includes: the device comprises a dissolved air tank 1, a cavitation piece 2, a control valve 4, an auxiliary port 18, a water inlet pipe 14 and a water outlet pipe 15. Wherein, dissolve gas pitcher 1 and be provided with control valve 4 that is used for admitting air or drainage, dissolve and prescribe a limit to out the dissolved air chamber in the gas pitcher 1, dissolve gas pitcher 1 and have the entry and the export of business turn over rivers, entry and export stagger on the horizontal direction, the entry is located the top of export, the entry links to each other with clothing processing apparatus's total inlet tube, the export links to each other with cavitation spare 2. The gas dissolving tank 1 further has an auxiliary port 18, and the control valve 4 is provided at the auxiliary port to control the opening and closing of the auxiliary port 18.

Through setting up control valve 4 in microbubble generator 100's supplementary mouth 18 department to the break-make of supplementary mouth 18 is controlled, and combines the export of dissolved air chamber, not only can guarantee that the incomplete water in the dissolved air intracavity of microbubble generator 100 can be discharged, can supply the air to dissolved air intracavity moreover, makes the interior quick recovery ordinary pressure of dissolved air chamber, guarantees that microbubble generator 100 can dissolve sufficient air when next use.

In an alternative embodiment of the present application, see fig. 4, the auxiliary port 18 is located above the outlet, i.e. the auxiliary port 18 is located higher than the outlet, and the auxiliary port 18 can be used for intake air. For example, the microbubble generator 100 includes the dissolved air tank 1, the inlet is located at or near the topmost portion of the dissolved air tank 1, the outlet is located at or near the bottommost portion of the dissolved air tank 1, and the auxiliary port 18 is located at or near the topmost portion of the dissolved air tank 1. When the micro-bubble generator 100 works, the control valve 4 is closed, water is introduced into the micro-bubble generator 100, and water flows through the inlet and enters the dissolved air cavity; after the micro-bubble generator 100 is used each time, water stops flowing to the inlet, the control valve 4 is opened, outside air enters the air dissolving cavity from the auxiliary port 18, normal pressure in the air dissolving cavity is quickly recovered, it is ensured that enough air can be dissolved when the micro-bubble generator 100 is used next time, and residual water in the air dissolving cavity is discharged through the outlet under the action of air pressure difference and self gravity.

In some embodiments of the present application, the outlet is connected to the water inlet header 51 through at least the second micro bubble nozzle 522, so that the outlet is connected to the tub through the second micro bubble nozzle 522 and the water inlet header 51. For example, as shown in fig. 4, the water outlet 102 of the microbubble generator 100 is connected to the water inlet manifold 51 through the second microbubble connecting pipe 522, and the microbubble water produced by the microbubble generator 100 is introduced into the tub through the second microbubble connecting pipe 522 and the water inlet manifold 51, and participates in the dissolution of the detergent in the tub, and the like, so as to improve the washing ratio of the laundry.

In another alternative embodiment of the present application, referring to fig. 3, the auxiliary port 18 is located below the outlet, when the microbubble generator 100 operates, the control valve 4 is closed, water is supplied into the microbubble generator 100, and water flows through the inlet into the dissolved air cavity; after having used microbubble generator 100 at every turn, stop to the entry water-flowing, and open control valve 4, when the position that exposes the export is fallen to the water level, the export that the external air can follow normally open state gets into in the dissolved air chamber, make the dissolved air intracavity resume the ordinary pressure fast, guarantee that microbubble generator 100 can dissolve sufficient air when next use, and because supplementary mouth 18 is in the on-state, and the position of supplementary mouth 18 is less than the position of export, the residual water in the dissolved air chamber receives the effect of atmospheric pressure difference and residual water self gravity, discharge from supplementary mouth 18, finally the residual water in the dissolved air chamber is exhausted.

When the second water inlet valve is opened, microbubbles can be generated using the microbubble generator. Specifically, the dissolved air tank 1 is supplied with dissolved air from the inlet, and at this time, the control valve 4 may be closed to close the auxiliary port 18. The water containing high concentration air solute enters the cavitation part 2, the cavitation part 2 utilizes the cavitation effect to produce micro bubbles, the water flow discharged from the cavitation part 2 contains a large amount of micro bubbles, and the micro bubble water can be used for washing and other various purposes. The above process is described in detail below with reference to fig. 5.

Fig. 5 is a schematic flow chart of a water injection control method according to a fifth embodiment of the present application.

In the embodiment of the present application, the set time period is preset, for example, may be preset for a built-in program of the laundry treatment device, or may be set by a user, which is not limited, for example, the set time period may be 20 seconds.

And step 204, controlling the first water inlet valve to be closed, and opening the second water inlet valve to continuously inject water to reach a second water level.

In the embodiment of the application, when the water filling duration of the first water inlet valve is greater than or equal to the set duration in the washing process, in order to improve the washing effect of the clothes, the first water inlet valve may be controlled to be closed, and the second water inlet valve is opened to continue to fill water to reach the second water level, so as to improve the content of micro bubbles in the water tub.

And step 205, controlling the first water inlet valve to be closed in a delayed mode, and opening the second water inlet valve to continuously inject water to reach a second water level.

In the embodiment of the application, when the water injection duration of the first water inlet valve is shorter than the set duration in the washing process, in order to flush the detergent (such as washing powder and laundry detergent) so as to facilitate sufficient dissolution of the detergent, the first water inlet valve may be controlled to be closed in a delayed manner, that is, the first water inlet valve is controlled to be opened continuously, until the water injection duration of the first water inlet valve is equal to the set duration, the first water inlet valve is closed, and the second water inlet valve is opened to continuously inject water to reach the second water level. Therefore, the water injection efficiency is ensured, and simultaneously, the content of micro bubbles in the washing water in the water containing barrel can be ensured, so that the washing effect of clothes is ensured.

And step 206, when the second water inlet valve is monitored to be opened, closing the control valve.

In an embodiment of the present application, the laundry treating apparatus may monitor an operating state of the second water inlet valve, wherein the operating state of the second water inlet valve includes an open state and a closed state. When the clothes treatment device monitors that the working state of the second water inlet valve is an opening state in a monitoring mode, namely when the second water inlet valve is monitored to be opened, the control valve can be closed, so that the situation that water flow and air flow out from the auxiliary port to reduce the air dissolving effect of the micro-bubble generator is avoided.

It should be noted that the present application only performs the example after

steps

204 and 205 in step 206, and in practical applications, when it is detected that the second water inlet valve is opened, that is, the second water inlet valve is opened to fill water, the control valve can be closed.

Furthermore, the present application only performs the example after steps 208 and 209-210 in step 206, and in practical applications, when the second water inlet valve is detected to be opened, that is, the second water inlet valve is opened to fill water, the control valve can be closed.

Therefore, in the present application, the control valve may be opened to discharge the residual water in the dissolved air chamber each time the second water inlet valve is closed. From this, can guarantee to dissolve in the gas jar and have sufficient air, guarantee that microbubble generator can dissolve sufficient air when using next time, promote microbubble generator's the gas effect that dissolves.

Specifically, the laundry processing apparatus may monitor the working state of the second water inlet valve, and may delay the opening of the control valve when it is monitored that the working state of the second water inlet valve is switched from the open state to the closed state, that is, when it is monitored that the second water inlet valve is switched from the open state to the closed state. For example, a 20 second delay is performed to allow the water in the microbubble generator to flow to the water tub, and when the 20 second delay is over, the control valve may be opened to drain the residual water in the dissolved air chamber.

As a possible implementation, when the control valve is opened for the set opening duration, the residual water in the dissolved air cavity is substantially drained, and at this time, the control valve may be closed. The set starting time period may be preset for a built-in program of the laundry treatment device, or may be set by a user, which is not limited thereto. For example, the set opening time period for opening the control valve every time may be set to 3 minutes, and after 3 minutes, the control valve may be automatically closed.
