Detailed Description

Reference will now be made in detail to the embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions 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 injecting water into the water tank without passing through the micro-bubble generator, and a second water inlet valve for injecting water into the water tank with passing through the micro-bubble 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 holding barrel, and the micro bubble water may be used to participate in a washing process of 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 that require the micro bubble water, such as cleaning a sealing ring, cleaning dirt, etc., of the laundry treatment apparatus, which is not limited thereto.

The laundry processing apparatus may be a drum washing machine, a pulsator washing machine, a washing and drying machine, or the laundry processing apparatus may be other types of apparatuses, 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 may include the steps of:

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 injection control method in the embodiment of the application can be applied to a clothes treatment device for automatically putting detergent, for example, when a user washes clothes, the detergent can be automatically put in by the clothes treatment device.

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 bucket in unit time after the first water inlet valve is opened is higher than that 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 to the water tub after the first water inlet valve is opened in unit time, if the second water inlet valve is controlled to be opened all the time to improve the washing effect of the laundry during water filling, and micro bubble water is filled into the water tub, the water filling time is long, and the operation time of the laundry treatment apparatus is too long. If the first water inlet valve is controlled to be opened all the time in order to improve the water injection efficiency during water injection, the content of air bubbles in the water containing barrel is low, and the washing effect of clothes cannot be guaranteed.

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, and thus other components of the laundry treatment apparatus may work normally, for example, the first water level, such as a heating water level, may be reached, and the heating unit may heat the wash water in the water tub, thereby 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.

Step 102, controlling the first water inlet valve and the second water inlet valve according to the executed washing stage to continuously inject water to reach a second water level.

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

Specifically, when the washing stage is a washing process, and when the water level reaches a first water level, 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 controlled to be opened to continue to supply water to a second water level, thereby increasing the content of the micro bubbles in the tub. Therefore, the water injection efficiency is ensured, the content of the microbubbles in the washing water in the water containing barrel can be ensured, the explosion energy of the microbubbles can accelerate the differentiation of the washing agent into smaller parts, the full dissolution of the washing agent is promoted, when stains on clothes are stubborn, the stains are difficult to be removed only by the dissolution of the washing agent or by the friction between the clothes, and the explosion energy of the microbubbles can enhance the dirt removing capability of the clothes, so that the cleaning effect of the clothes is ensured.

It can be understood that, since the operation time of the laundry treatment apparatus is limited and the dirt in the laundry is substantially removed during the washing stage, only a small amount of micro bubbles are required to remove the detergent remaining on the laundry during the rinsing stage. Therefore, in the present application, when the washing phase is a rinsing process, and when the water level reaches the first water level, in order to increase the content of micro bubbles in the water tub, the water injection efficiency is increased at the same time, so as to increase the operation efficiency of the laundry treatment apparatus, the first water inlet valve may be maintained open, and the second water inlet valve may be controlled open, so as to continue injecting water until the second water level is reached. Therefore, the water injection efficiency is ensured, the content of the microbubbles in the water containing barrel can be increased, the detergent stained on the clothes can be dissolved in water as soon as possible through the explosion energy of the microbubbles, and the detergent residue on the clothes is avoided. 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.

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

and controlling the first water inlet valve and the second water inlet valve to continuously inject water to reach a second water level according to the executed washing stage. Therefore, the water injection efficiency is ensured, the content of the microbubbles in the washing water in the water containing barrel can be ensured, the explosion energy of the microbubbles can accelerate the differentiation of the washing agent into smaller parts, the full dissolution of the washing agent is promoted, when stains on clothes are stubborn, the stains are difficult to be removed only by the dissolution of the washing agent or by the friction between the clothes, and the explosion energy of the microbubbles can enhance the dirt removing capability of the clothes, so that the cleaning 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, and the detergent is prevented from being remained 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 residual detergent on the clothes is further reduced.

The water injection control method is applied to a clothes treatment device capable of automatically putting in detergent, when clothes are washed, in order to flush away the detergent, the detergent is convenient to be fully dissolved, the first water inlet valve can be connected with the inlet of the detergent box, a detergent cavity for containing the detergent is defined in the detergent box, and when the first water inlet valve is opened, the detergent contained in the detergent box can be flushed away through water flow, so that the washing water dissolved or containing the detergent flows into the water containing barrel. Before washing the laundry, the detergent box is controlled to put detergent. The above process is described in detail below with reference to fig. 2.

Fig. 2 is a schematic flowchart of a water injection control method according to a second embodiment of the present disclosure.

As shown in fig. 2, the water injection control method may include the steps of:

step 201, controlling a detergent box to put detergent.

In the embodiment of the application, the detergent may be laundry detergent, washing powder, softener, and the like, for example, during a washing process, the detergent box may be controlled to put the laundry detergent and the washing powder, and during a rinsing process, the detergent box may be controlled to put the softener.

Step 202, controlling the first water inlet valve to be opened discontinuously.

When the detergent is flushed, if the first water inlet valve is controlled to be opened all the time, water is accumulated in the detergent box, the water flow impulsive force is reduced, and the detergent in the detergent box cannot be flushed completely. Therefore, in the application, the first water inlet valve can be controlled to be opened discontinuously, namely, the first water inlet valve is controlled to be opened for a period of time and then closed, so that water flows to the water barrel, and then the first water inlet valve is controlled to be opened again, so that the impulsive force of the water flow is increased instantly, and the probability that detergent in the detergent box is washed cleanly can be improved.

Step 203, the first water inlet valve is opened to fill water to reach a first water level.

It should be noted that, only opening the second water inlet valve cannot flush the detergent, so that the washing effect of the laundry cannot be guaranteed, and the water inflow of the micro bubble generator is much smaller than the water inflow of the detergent box. If the first water inlet valve is controlled to be opened all the time in order to improve the water injection efficiency during water injection, the content of air bubbles in the water containing barrel is low, and the washing effect of clothes cannot be guaranteed.

Therefore, in the present application, in order to improve the water filling efficiency and simultaneously ensure the washing effect of the laundry, when filling water into the tub, only the first water inlet valve may be controlled to be opened at first, so that the water containing amount in the tub rapidly reaches the first water level.

In step 204, the washing phase to be performed is determined.

And step 205, if the washing stage is a washing process, controlling the first water inlet valve to be closed, and controlling the second water inlet valve to be opened so as to continuously inject water until reaching a second water level.

In the embodiment of the application, in order to improve the washing effect of the clothes, the first water inlet valve can be controlled to be closed, and the second water inlet valve is controlled to be opened, so that water is continuously injected to reach the second water level, and the content of micro bubbles in the water bucket is improved.

And step 206, if the washing stage is a rinsing process, keeping the first water inlet valve open, and controlling the second water inlet valve open to continuously inject water until reaching the second water level.

It can be understood that, since the operation time of the laundry treating apparatus is limited and the contaminants in the laundry are substantially removed during the washing stage, only a small amount of micro bubbles are required to remove the detergent remaining on the laundry during the rinsing stage. Therefore, in the present application, when the washing stage is a rinsing process, and when the water level reaches the first water level, in order to increase the content of the micro bubbles in the tub and simultaneously increase the water injection efficiency, thereby increasing the operation efficiency of the laundry treatment apparatus, the first water inlet valve may be maintained open, and the second water inlet valve may be controlled open, so as to continue to inject water until the second water level is reached.

the washing agent is put into the washing agent box through control, and the first water inlet valve is controlled to be opened discontinuously, so that the impulsive force of water flow in the washing agent box can be improved, and the probability that the washing agent in the washing agent box is washed cleanly is improved.

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. And (3) automatically feeding the washing agent, opening the first water inlet valve for washing for 10 seconds after the washing agent is fed, and controlling the first water inlet valve to be intermittently opened.

4. And (5) finishing the feeding, and taking the first washing grade as a target water level when water is injected for the first time. 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 reaches the first water level, the first water inlet valve can be closed, and the second water inlet valve can be opened to reach the target water level.

5. 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.

6. 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 first wash water level, this step is not performed, and if the target water level is adjusted to the second wash water level, the second water inlet valve is opened to fill the water during the entire filling process.

7. 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 water inlet valve opened by the latest water injection, for example, when the water inlet valve opened by the latest water injection is the first water inlet valve, controlling the first water inlet valve and the second water inlet valve to be simultaneously opened for replenishing water, and when the water inlet valve opened by the latest water injection is the second water inlet valve, continuously controlling the second water inlet valve to be opened for replenishing water.

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 panel set water level, and generally enters a third water level, such as a third water level for washing, under the condition that the default water level is automatic, 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 manner, the washing is started after the water injection reaches the second water level, at this time, in the washing process, because the clothes absorb water, the water level is reduced, the water filling barrel needs to be replenished, and the roller stops rotating in the water filling process so as to ensure the stability of the water level detection.

Specifically, at least one of the first and second water inlet valves may be controlled to be opened for replenishing water according to the water inlet valve opened at the last water filling. 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, referring to fig. 3, when water is filled, it may be determined whether the micro bubble generating function is turned on, and if not, water is normally filled, i.e., the first water filling valve is opened to fill water into the water tub, and if so, it is determined whether the water is filled up to the first water level by opening the first water filling valve.

If the water level reaches the first water level, judging whether the washing stage is a washing process, if so, independently controlling a second water inlet valve to inject water, judging whether the water injection water 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 a third water level.

And if the rinsing process is carried out, controlling the first water inlet valve and the second water inlet valve to open, 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. 4, fig. 4 is a schematic structural diagram of a microbubble generator according to a fourth 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 the 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 piece 2. The dissolved air tank 1 is also provided with an auxiliary port 18, and the control valve 4 is arranged at the auxiliary port and used for controlling the on-off 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. 5, 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. 5, 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. 4, 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 using microbubble generator 100 at every turn, stop to the entry water, and open control valve 4, when the water level descends to the position that exposes the export, the export that the open state was followed to the outside air can be followed in getting into the dissolved air chamber, make the interior normal pressure that resumes of dissolved air chamber fast, guarantee that microbubble generator 100 can dissolve sufficient air when using next time, and because auxiliary port 18 is in the on-state, and auxiliary port 18's position is less than the position of export, the residual water in the dissolved air chamber receives the effect of air pressure difference and residual water self gravity, discharge from auxiliary port 18, finally the residual water in the dissolved air chamber is discharged.

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.

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 of the auxiliary port to reduce the air dissolving effect of the micro-bubble generator is avoided.

It should be noted that, after the second water inlet valve is closed, residual water may be in the air dissolving cavity, and if the residual water is not discharged through the air release, the residual water may affect the air dissolving effect of the micro-bubble generator. 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.
