detailed description

The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the application, but should not be understood as a limitation to the application.

The following describes the water injection control method, device, and laundry treatment device of the embodiments of the present application with reference to the drawings.

FIG. 1 is a schematic flow chart of the water injection control method provided in Embodiment 1 of the application.

The water injection control method of the embodiment of the present application is applied to a clothes treatment device, and the clothes treatment device includes: a first water inlet valve that does not flow through the microbubble generator and fills the bucket, and the microbubble generator fills the bucket with water The second inlet valve. Among them, the micro bubble generator is provided with a control valve.

In the embodiment of the present application, the microbubble generator includes an air dissolving tank, and the dissolving tank is provided with a control valve for air intake or exhaust. The microbubble generator is used to make microbubble water and pass it into the bucket. The microbubble water can be used to participate in the washing process of clothes, or the microbubble water can be used to participate in the rinsing process of the clothes, or the microbubble water can also participate In other processes that require the use of microbubble water in the clothing treatment device, such as cleaning the seal ring and cleaning dirt, there is no restriction on this.

It should be noted that during the laundry washing process, the rupture of the microbubbles when washing with microbubble water can accelerate the dissolution of the detergent and make the dissolution more fully, which can achieve the purpose of reducing the amount of detergent. During the rinsing process, the microbubble water can more thoroughly remove the detergent remaining on the clothes, avoiding the phenomenon of a large amount of detergent remaining after the clothes are washed.

In the embodiment of the present application, after the second water inlet valve that flows through the microbubble generator and injects water into the bucket is opened, the microbubble water flow first flows through the dissolved gas tank and then flows into the bucket through the dissolved gas tank. However, the actual use process It is found that after the second water inlet valve is closed, there will be residual water in the dissolving tank. If the residual water is not discharged, the dissolving effect will be affected. Therefore, every time the second water inlet valve is closed, the dissolution must be controlled. The drain control valve on the gas tank is used to drain the residual water in the gas tank.

The laundry treatment device may be a drum washing machine, a pulsator washing machine, a washer-dryer integrated machine, or the laundry treatment device may also be another type of device, which is not limited here. The tub is a tub used to process 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.

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

Step 101: Open the first water inlet valve to inject water to reach the first water level.

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

The water injection control method of the embodiment of the present application can be applied to a laundry treatment device that automatically puts detergent. For example, every time a user washes clothes, the laundry treatment device can automatically put detergent or it can also be applied to non-automatic detergent injection. For example, the user manually puts detergent into the tub every time the user washes the clothes.

In the embodiment of this application, when the first water inlet valve is opened, the water flow does not flow through the microbubble generator, but directly injects water into the bucket, and when the second water inlet valve is opened, the water flows through the microbubble generator to Fill the bucket with water. Wherein, the amount of water flowing into the tub per unit time after the first water inlet valve is opened is higher than the amount of water flowing into the microbubble generator per unit time after the second water inlet valve is opened.

It is understandable that since the amount of water entering the microbubble generator per unit time is much smaller than the amount of water flowing into the bucket after the first water inlet valve is opened, if the water is filled, in order to improve the washing effect of the clothes, the second inlet is always controlled. When the water valve is opened and microbubble water is injected into the bucket, the water injection time will be longer and the operation time of the laundry treatment device will be too long. However, if the first water inlet valve is always controlled to open during the water injection in order to improve the water injection efficiency, the bubble content in the water bucket is low, and the washing effect of the clothes cannot be guaranteed.

Therefore, in this application, in order to improve the water injection efficiency and ensure the washing effect of the clothes, when filling water into the bucket, only the first water inlet valve can be controlled to open first, so that the amount of water in the bucket quickly reaches the first water level Therefore, other components of the laundry treatment device can work normally. For example, when the first water level is reached, such as the heating water level, the heating unit can heat the washing water in the tub to improve the operating efficiency of the laundry treatment device.

Among them, the first water level can be measured by a sensor, and the sensor can collect water level frequency, and determine whether the amount of water in the bucket reaches the first water level according to the water level frequency. As a possible scenario, when the water injection control method of the embodiment of the present application is applied to a laundry treatment device that automatically puts detergent, when washing clothes, after controlling the detergent box to put detergent, the first water inlet valve can be controlled intermittently Open, that is, control the first water inlet valve to open for a period of time and then close it to let the water flow to the tub, and then control the first water inlet valve to reopen, so that the momentum of the water flow increases instantaneously, which can lift the detergent inside the detergent box Probability of being washed clean. In order to improve the water filling efficiency and ensure the washing effect of the clothes, when filling water into the bucket, only the first water inlet valve can be controlled to open, so that the amount of water in the bucket quickly reaches the first water level.

Step 102: Control at least one of the first water inlet valve and the second water inlet valve to continue water injection, and monitor the on-off state of the second water inlet valve.

In the embodiment of the present application, when the laundry treatment device applied by the water injection control method is automatic detergent injection and non-injection detergent respectively, the water injection control process for the first water inlet valve and the second water inlet valve is different. The scene is explained in detail. In the process of controlling at least one of the first water inlet valve and the second water inlet valve to continue water injection, it is necessary to monitor the on-off state of the second water inlet valve, so as to perform on-off control of the control valve according to the on-off state of the second water inlet valve.

As a possible scenario, when the water injection control method is applied to a laundry treatment device that automatically puts detergent in, when the washing stage executed is a washing process, and when the water level reaches the first water level, in order to improve the washing effect of the clothes, The first water inlet valve can be controlled to close, and the second water inlet valve can be controlled to open, so as to continue to inject water to reach the second water level, thereby increasing the content of microbubbles in the bucket. Wherein, the second water level is preset, for example, it may be the second washing water level. Therefore, while ensuring the efficiency of water injection, the content of microbubbles in the washing water in the tub can be ensured. The blasting energy of the microbubbles can speed up the differentiation of detergent into smaller parts, promote the full dissolution of detergent, and when the clothes are on When the stains are stubborn, it is difficult to remove the stains only by detergent dissolution or friction between clothes, and the bursting energy of microbubbles can enhance the stain removal ability of clothes and ensure the washing effect of clothes.

When the washing stage executed is the rinsing stage, since the operating time of the laundry treatment device is limited, and the stains in the clothes are basically removed during the washing stage, therefore, only a small amount of microbubbles are needed to remove the remaining washing on the clothes during the rinsing stage. Agent. Therefore, when the washing stage executed is the rinsing process and when the water level reaches the first water level, in order to increase the content of microbubbles in the tub and at the same time increase the water injection efficiency, thereby improving the operating efficiency of the laundry treatment device, the first water intake can be maintained The valve is opened and the second inlet valve is controlled to open to continue water injection. As a result, while ensuring the efficiency of water injection, the content of microbubbles in the tub can be increased, and the blasting energy of the microbubbles can dissolve the detergent contaminated on the clothes in the water as soon as possible to avoid residual detergent on the clothes. In addition, the washing water contains a large number of microbubbles, which can also reduce the amount of detergent and further reduce the residual detergent on the clothes.

As another possible scenario, when the water injection control method is applied to a laundry treatment device that does not automatically put detergent, the user pours detergent (or laundry detergent, washing powder, softener, etc.) into the tub and washes The agent is stacked in one place. In order to facilitate the full dissolution of the detergent, the first water inlet valve can be controlled in advance for a set time period to disperse the detergent, that is, to flush the detergent, so as to facilitate the full dissolution of the detergent.

When the washing stage is a washing process, if the water injection time of the washing process is greater than or equal to the set time, in order to improve the washing effect of the clothes, the first water inlet valve can be controlled to close, and the second water inlet valve can be opened to continue water injection. The second water level to increase the content of microbubbles in the bucket. And if the water injection time of the washing process is less than the set time, in order to flush out the detergent (such as washing powder, laundry liquid) so as to facilitate the full dissolution of the detergent, the first water inlet valve can be controlled to delay closing, that is, the first water inlet valve can be controlled to be closed. A water inlet valve continues to open until the water injection time of the first water inlet valve is equal to the set time period, close the first water inlet valve and open the second water inlet valve to continue water injection to reach the second water level. As a result, while ensuring the efficiency of water injection, the detergent can be flushed out, thereby facilitating the full dissolution of the detergent, and at the same time, the content of microbubbles in the washing water in the tub can be ensured. The blasting energy of the microbubbles can speed up the detergent. Divide into smaller parts to promote the full dissolution of the detergent, and when the stains on the clothes are stubborn, it is difficult to remove the stains only by the detergent or the friction between the clothes, and the explosion energy of the microbubbles It can enhance the dirt removal ability of clothes and ensure the washing effect of clothes.

When the washing stage executed is the rinsing process, if the water injection time of the rinsing process is greater than or equal to the set time, in order to increase the content of microbubbles in the bucket and ensure the cleaning effect, the second water inlet valve can be controlled to open until The water injection reaches the second water level. And if the water injection time of the rinsing process is less than the set time, in order to improve the water injection efficiency, and at the same time, in order to flush out the detergent (such as softener), so as to facilitate the full dissolution of the detergent, the first water inlet valve can be controlled to continue to inject water. Make the water injection time reach the set time, and then control the second water inlet valve to open until the water injection reaches the second water level. As a result, while ensuring the efficiency of water injection, the detergent can be flushed out so as to facilitate the full dissolution of the detergent. At the same time, the content of microbubbles in the bucket can also be increased. The explosion energy of the microbubbles can make the clothes stained. The detergent is dissolved in the water as soon as possible to avoid residual detergent on the clothes. In addition, the washing water contains a large number of microbubbles, which can also reduce the amount of detergent and further reduce the residual detergent on the clothes.

It should be noted that, in the above embodiment, when the water injection time of the rinsing process is greater than or equal to the set time, the first water inlet valve and the second water inlet valve are controlled to be opened at the same time, and water is injected into the tub. The reason is that the operating time of the laundry treatment device is limited, and the stains in the laundry are basically removed. At this time, only a small amount of microbubbles are required to remove the detergent remaining on the laundry.

As a possible implementation method, after washing for a period of time, water will be injected again to the panel set water level. In the case of the default water level is automatic, it will generally enter the third water level, such as the third water level for washing. At this time, you can control the first water level. A water inlet valve and a second water inlet valve are opened, and water is continued to be injected to the third water level. Specifically, when the water is injected to the second water level, it can be judged whether the final target water level is reached, if it is, the water injection is stopped, if not, the first water inlet valve and the second water inlet valve are controlled to open, and the water injection continues to the final target The water level is recorded as the third water level in the embodiment of this application.

As a possible implementation method, the washing starts after the water injection reaches the second water level. At this time, during the washing process, the water level will drop due to water absorption by the clothes. The bucket needs to be filled with water. During the filling process, the drum stops rotating to ensure the water level. Stability of detection.

Specifically, at least one of the first water inlet valve and the second water inlet valve can be controlled to open for replenishing water according to the water inlet valve opened during the last water injection. For example, when the inlet valve opened by the most recent water injection is the first inlet valve, the first inlet valve and the second inlet valve can be controlled to open at the same time for water replenishment, and the inlet valve opened during the most recent water injection When it is the second water inlet valve, you can continue to control the opening of the second water inlet valve to supplement water.

It should be noted that in actual application, during the process of opening the second water inlet valve to fill water, if the second water inlet valve fails, the washing program will alarm. At this time, the washing program cannot be run to end. Therefore, as a possible implementation of the embodiments of the present application, the sensor can detect the water level frequency change in real time or periodically, and determine whether the water level frequency change is lower than the preset threshold, and if so, control the first water inlet The valve is opened to prevent the washing program from alarming after the second water inlet valve fails, and the operation cannot be ended, so as to ensure that the laundry treatment device can be washed normally and the washing program is guaranteed to end normally. Among them, the water level frequency change amount is preset, for example, it can be 30 Hz.

For example, the sensor can detect the water level frequency every one minute, and obtain the water level frequency change by making the difference between the two adjacent water level frequencies, and then determine whether the water level frequency change is lower than a preset threshold, such as lower than 30 Hz. If so, The first water inlet valve is opened to prevent the washing program from alarming after the second water inlet valve fails and the operation cannot be ended.

In the embodiment of the present application, in the process of controlling the first water inlet valve and the second water inlet valve to continue water injection, the laundry treatment device is required to monitor the on-off state of the second water inlet valve, where the second water inlet valve The switch state includes an open state and a closed state, so that the state of the control valve for draining the gas tank is controlled according to the monitored switch state of the second water inlet valve.

Step 103: Monitor to determine that the second water inlet valve is open, and close the control valve.

In the embodiment of the present application, the laundry treatment device can monitor the on-off state of the second water inlet valve, where the working state of the second water inlet valve includes an open state and a closed state. When the clothes treatment device monitors the working state of the second water inlet valve to be open by listening, etc., the control valve can be closed to prevent water and air from flowing out of the auxiliary port and reduce the dissolved air effect of the micro bubble generator Happening.

It should be noted that when monitoring the on-off state of the second water inlet valve in step 102, once it is monitored that the second water inlet valve is in an open state, the control valve needs to be closed immediately to prevent water and air from flowing out of the auxiliary port. Reduce the dissolved air effect of the micro bubble generator.

Step 104: Monitor to determine that the second water inlet valve is closed, and open the control valve to drain the micro bubble generator.

In the embodiment of the present application, after the second water inlet valve is closed, there will be residual water in the cavity of the gas dissolving tank. If it is not discharged through the gas discharge, the residual water will affect the dissolving effect of the microbubble generator. Therefore, in this application, every time it is monitored that the second water inlet valve is closed, the control valve can be opened to discharge the residual water in the cavity of the gas tank. As a result, it can be ensured that there is sufficient air in the air-dissolving tank, and the micro-bubble generator can dissolve enough air when it is used next time, and the air-dissolving effect of the micro-bubble generator is improved.

The above technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

On the other hand, if monitoring determines that the second inlet valve is closed, the control valve is opened to drain water. By monitoring to determine the on-off state of the second water inlet valve to control the control valve, the residual water in the microbubble generator can be discharged to ensure that there is sufficient air in the gas tank to ensure that the microbubble generator can be used next time Dissolve enough air to improve the dissolving effect of the microbubble generator, and also avoid the problem that the residual water in the cavity of the dissolving tank reduces the dissolving effect of the microbubble generator.

FIG. 2 is a schematic flow chart of the water injection control method provided in the second embodiment of the application. In order to avoid the frequent opening and closing actions of the second water inlet valve, the control valve's drainage time is insufficient and the drainage effect is not achieved. In this embodiment, when the second water inlet valve is monitored to be in an open state, the control valve is immediately closed; When it is monitored that the second water inlet valve is closed, the control valve is opened with a delay to drain water, and the control valve is closed again when the drain reaches a certain period of time after opening the control valve. The above process will be described in detail below in conjunction with FIG. 2.

As shown in Figure 2, the water injection control method may include the following steps:

Step 201: Open the first water inlet valve to inject water to a first water level.

Step 202: Control at least one of the first water inlet valve and the second water inlet valve to continue water injection, and monitor the on-off state of the second water inlet valve.

Step 203: Monitor to determine that the second water inlet valve is open, and close the control valve.

In the embodiment of the present application, for the implementation process of step 201 to step 203, refer to the implementation process of step 101 to step 103 in the embodiment, which will not be repeated here.

In step 204, it is detected that the second water inlet valve is closed, and the timing is started.

Specifically, the clothing treatment device may monitor the working state of the second water inlet 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, it is monitored that the second water inlet valve is switched from open When it is off, start timing.

On the one hand, it is determined by timing whether the second water inlet valve is in a frequently switching state. If it is not in the frequent switching state, the control valve can be opened, which effectively avoids the phenomenon that the second inlet valve frequently opens and closes, which causes the control valve to drain for insufficient time and no drainage effect, which is beneficial to the dissolved gas tank All the microbubble water flows into the water bucket to remove the residual water in the dissolved air cavity.

On the other hand, by delaying the opening of the control valve, the time for the microbubble water in the gas tank to flow into the water tank after the second water inlet valve is closed, so that the microbubble water is discharged from the gas tank by gravity, and the timer ends. After that, only residual water that cannot be discharged by gravity remains in the dissolved gas tank.

In step 205, the timing reaches the first set time period, and the control valve is opened to drain the micro bubble generator.

Among them, the value range of the first set duration is 10 seconds to 30 seconds, and the control valve is opened with a delay. For example, enter a 20-second delay to make the water in the microbubble generator flow to the bucket, and when the 20-second delay is over, open the control valve to drain water. This is because the first set time is too long, which will cause the laundry to be washed If the time is too long and the first set time is too short, the microbubble water discharged from the gas tank by gravity may not flow to the bucket in time, and the second water inlet valve is likely to operate frequently, leading to control The corresponding frequent action of the valve.

In the embodiment of the present application, when the timing reaches the first set time period, the control valve is opened to drain the micro bubble generator. As a result, it can be ensured that there is sufficient air in the air-dissolving tank, and the micro-bubble generator can dissolve enough air when it is used next time, and the air-dissolving effect of the micro-bubble generator is improved.

Step 206: Open the control valve to drain water for a second set time period, and close the control valve again.

In the embodiment of the present application, when the control valve is opened for the second set time period, the residual water in the cavity of the gas dissolving tank is basically eliminated. At this time, the control valve can be closed. Wherein, the second set time period may be preset for a built-in program of the laundry treatment device, or may be set by the user, which is not limited. For example, the upper limit of the value range of the second setting time can be three minutes, which effectively avoids the phenomenon that when the second water inlet valve frequently opens and closes, the drainage time of the control valve is insufficient and the drainage effect is not achieved. When it is opened for three minutes, the residual water in the cavity of the gas tank can be basically eliminated. After three minutes, the control valve can be automatically closed.

As an example, refer to FIG. 3, which is a schematic diagram of the control process of the control valve provided in the second embodiment of the application.

When the laundry treatment device has the function of generating microbubbles, and the condensation valve is not opened, and in the non-test mode, it can be judged whether the second water inlet valve is open. If the second water inlet valve is opened, the control valve is closed and the waiting state is entered. Judge whether the second water inlet valve is closed, if yes, enter the delay state, the delay time is 20 seconds, judge whether it reaches 20 seconds, if yes, then enter the working state, open the control valve, and judge that the control valve is open for the set open time If yes, it will enter the stop state, close the control valve, and enter the idle state.

By monitoring that the second inlet valve is closed, start timing, the timing reaches the first set time, open the control valve to drain water, open the control valve to drain water for the second set time, close the control valve again, not only can dissolved gas All the microbubble water produced in the tank flows into the bucket, which can also ensure that there is sufficient air in the dissolved air tank, which ensures that the microbubble generator can dissolve enough air when it is used next time, and increase the dissolved air of the microbubble generator The effect is that when the second water inlet valve frequently opens and closes, the drain time of the control valve is insufficient, and the drain effect is not achieved.

As an example, referring to Figure 4, when water is injected, it can be determined whether the microbubble generation function is turned on. If not, the water is normally injected, that is, the first water injection valve is opened to inject water into the bucket, if yes, it is determined to open the first water injection valve Whether the water injection reaches the first water level.

If it reaches the first water level, it is judged whether the washing stage is a washing process. If it is a washing process, the second water inlet valve is separately controlled for water injection, and it is judged whether the water injection level reaches the second water level. If not, the first inlet is controlled. The water valve and the second water inlet valve are opened, and water is continued to be injected to the third water level.

If it is a rinsing process, the first water inlet valve and the second water inlet valve are controlled to open, and water injection is continued. Judge whether the water injection level reaches the target water level, if so, end this water injection.

It should be noted that in the process of controlling the water injection of the first water inlet valve and the second water inlet valve, the on-off state of the second water inlet valve should be monitored in real time. When it is monitored that the second water inlet valve is open, the control valve should be closed. To prevent water and air from flowing out of the auxiliary port and reduce the dissolving effect of the microbubble generator, when the second water inlet valve is monitored to be closed, the control valve can be opened to remove the residual water in the cavity of the dissolving tank , In order to ensure that there is sufficient air in the dissolved air tank, to ensure that the micro-bubble generator can dissolve enough air when it is used next time, and to enhance the dissolving effect of the micro-bubble generator.

In order to realize the above embodiments, this application also proposes a water injection control device.
