In the related art, water treatment equipment with water purification function generally stores purified water in a clean water tank in a cold water tank in advance, so that the cold water tank has available cold water for users to use at any time.

However, in the process of replenishing water from the clean water tank to the cold water tank, overflow and leakage may occur due to incorrect judgment of the water level in the cold water tank, resulting in damage to the water treatment equipment or safety hazards.

Please refer to FIG. 1 and FIG. 4 , a control method of a water treatment device 200 according to an embodiment of the present invention, the water treatment device 200 includes a clean water tank 10, a cold water tank 12 and a water replenishment pump 14, the water replenishment pump 14 is used to replenish water to the cold water tank 12 using water from the clean water tank 10, the cold water tank 12 of the water treatment device 200 is provided with a low water level, a high water level and a protection water level, and the protection water level is higher than the high water level, the control method of the water treatment device 200 includes:

Step S101: in the process of controlling the water supply pump 14 to start so that the clean water tank 10 supplies water to the cold water tank 12, when it is detected that the water level of the cold water tank 12 exceeds the protection water level, the water supply pump 14 is controlled to be turned off.

In the control method of the above-mentioned water treatment equipment 200, by setting a protective water level higher than the high water level, during the water replenishment process, when it is detected that the water level of the cold water tank 12 exceeds the protective water level, the water replenishment pump 14 is controlled to be closed, thereby preventing the cold water tank 12 from overflowing and leaking to a certain extent, and effectively protecting the water treatment equipment 200.

Specifically, the water treatment device 200 generally includes a clean water tank 10 and a cold water tank 12. The clean water tank 10 stores treated clean water, and the cold water tank 12 is connected to the clean water tank 10. At the same time, the cold water tank 12 has a water outlet, and the user can drink water through the water outlet. In order for the water treatment device 200 to provide cold water in a timely manner, it is necessary to ensure that there is a certain amount of water storage in the cold water tank 12. At the same time, in the process of replenishing cold water from the clean water tank 10, it is also necessary to detect the water level in the cold water tank 12 to avoid overflow of the water level in the cold water tank 12 or leakage of the cold water tank 12.

A low water level, a high water level and a protection water level are provided in the cold water tank 12. The protection water level is higher than the high water level, and the high water level is higher than the low water level. The low water level and the high water level are used to monitor and control the water storage capacity in the cold water tank 12.

At the same time, the water replenishment pump 14 is controlled to be turned on so that the clean water tank 10 replenishes water to the cold water tank 12. When the water level protection level or high water level of the cold water tank 12 is detected, the water replenishment pump 14 is controlled to be turned off. In this way, it can be avoided that the water volume exceeds the capacity of the cold water tank 12 during the water replenishment process and causes overflow and leakage.

During the water replenishment process, the water replenishment pump 14 is turned on to make the clean water tank 10 replenish water to the cold water tank 12, and the water level in the cold water tank 12 is detected at the same time. When the water level in the cold water tank 12 is higher than the high water level, the water replenishment pump 14 is controlled to be closed to stop the clean water tank 10 from replenishing water to the cold water tank 12.

In order to avoid detection failure at the high water level, a protection water level is set above the high water level. When the water level in the cold water tank 12 exceeds the high water level but is not detected, the water replenishment pump 14 is controlled to be turned off when it is detected that the water level of the cold water tank 12 exceeds the protection water level. In this way, continuous water replenishment can be avoided in the case of high water level detection failure, and overflow and leakage of the cold water tank 12 can be prevented to a certain extent.

Referring to FIG. 3 , in some embodiments, the control method of the water treatment device 200 includes:

Step S103 : when the water level in the cold water tank 12 is lower than the high water level and is maintained for a time period longer than a first preset time period, the water replenishment pump 14 is controlled to start so that the clean water tank 10 replenishes water to the cold water tank 12 .

In this way, it is possible to replenish water into the cold water tank 12 in a timely manner, and at the same time it is possible to avoid replenishing water too frequently to affect the service life of the water replenishing pump 14.

Specifically, when the water level in the cold water tank 12 is lower than the high water level, water can be replenished into the cold water tank 12. In the use scenario of the water treatment device 200, there may be a situation where the user continuously receives water. At this time, if water replenishment is started when the water level in the cold water tank 12 is lower than the high water level, water replenishment will be too frequent, and the water replenishment pump 14 will also be frequently turned on and off, resulting in damage to the working life of the water replenishment pump 14.

Therefore, after the water level in the cold water tank 12 is lower than the high water level and remains longer than the first preset time, the water replenishment pump 14 is controlled to start so that the clean water tank 10 replenishes water to the cold water tank 12, which can avoid excessive replenishment and damage to the working life of the water replenishment pump 14.

After water is added, the timing is reset, and the water level detection is continued to wait for the next timing.

In one embodiment, the first preset time is two minutes. When the water level in the cold water tank 12 is lower than the high water level, the timing starts. After the timing reaches two minutes, the water replenishment pump 14 is controlled to start so that the clean water tank 10 replenishes water to the cold water tank 12.

In some embodiments, the first preset time length is greater than or equal to 2 minutes and the first preset time length is less than or equal to 5 minutes.

In this way, the frequency of replenishing water into the cold water tank 12 can be controlled.

Specifically, the first preset time length is greater than or equal to 2 minutes and the first preset time length is less than or equal to 5 minutes. For example, the first preset time length may be 2 minutes, 2.5 minutes, 3 minutes, 3.5 minutes, 4 minutes, 4.5 minutes or 5 minutes, or any other value between greater than or equal to 2 minutes and less than or equal to 5 minutes. If the first preset time length is less than 2 minutes, it will cause frequent water replenishment in the cold water tank 12, and the water replenishment pump 14 will work frequently, thereby damaging the service life of the water replenishment pump 14. If the first preset time length is greater than 5 minutes, it will cause insufficient water storage in the cold water tank 12.

The first preset time can be set according to the capacity of the cold water tank 12, user preferences and other factors. For example, when the capacity of the cold water tank 12 is large, a longer first preset time can be set, so that the water storage in the cold water tank 12 is sufficient and frequent water replenishment can be avoided. For example, when the user uses the water treatment device 200 frequently, a shorter first preset time can be set, so that a certain water replenishment frequency can be maintained, ensuring the water storage while avoiding frequent water replenishment.

Referring to FIG. 4 , in some embodiments, the control method of the water treatment device 200 includes:

Step S105 : when the water level in the cold water tank 12 is lower than the low water level, the water replenishment pump 14 is controlled to start so that the clean water tank 10 replenishes water to the cold water tank 12 .

In this way, when the amount of water stored in the cold water tank 12 is small, rapid water replenishment can be achieved.

Specifically, when the water level in the cold water tank 12 is lower than the low water level, it indicates that the water storage in the cold water tank 12 is already less. When the water level in the cold water tank 12 is lower than the low water level, the water replenishment pump 14 is immediately controlled to start so that the clean water tank 10 replenishes water to the cold water tank 12, thereby realizing rapid water replenishment and avoiding the inability to discharge water due to insufficient water storage.

Referring to FIG. 5 and FIG. 6 , in certain embodiments, the control method of the water treatment device 200 includes:

Step S107: During the process of controlling the water replenishment pump 14 to start replenishing water from the clean water tank 10 to the cold water tank 12, when it is detected that the working time of the water replenishment pump 14 is greater than the second preset time and the water level in the cold water tank 12 is not higher than the high water level or the protection water level, the water replenishment pump 14 is controlled to be turned off to stop replenishing water from the clean water tank 10 to the cold water tank 12.

In this way, abnormal water replenishment can be detected, and the water replenishment pump 14 can be controlled in time to stop replenishing water.

Specifically, since the flow rate of the water replenishment pump 14 is known and is a fixed value, and the capacity of the cold water tank 12 is known, a unique relationship between the working time of the water replenishment pump 14 and the current water replenishment amount can be established. On this basis, the current water storage amount in the cold water tank 12 can be obtained by monitoring the working time of the water replenishment pump 14.

In the process of controlling the water replenishment pump 14 to start so that the clean water tank 10 replenishes water to the cold water tank 12, the timing starts after the water replenishment pump 14 starts working. When it is detected that the working time of the water replenishment pump 14 is greater than the second preset time and the water level in the cold water tank 12 is not higher than the high water level or the protection water level, the water replenishment pump 14 is controlled to be turned off so that the clean water tank 10 stops replenishing water to the cold water tank 12. Among them, when the water replenishment pump 14 works for the second preset time, the water storage in the cold water tank 12 reaches the high water level.

When the working time of the water replenishment pump 14 reaches the second preset time, according to the relationship between the working time and the current water replenishment amount, the water storage in the cold water tank 12 should have reached the high water level. If the signal that the water storage in the cold water tank 12 has reached the high water level is not detected at this time, it means that the current high water level detection is invalid. At this time, the water replenishment pump 14 is controlled to stop replenishing water, which prevents the cold water tank 12 from overflowing and leaking to a certain extent, and can effectively protect the water treatment equipment 200.

The timing is reset after the water replenishment pump 14 stops replenishing water, and the timing is resumed after the water replenishment pump 14 starts working next time.

Furthermore, the second preset time length can be set to be the time length when the water storage in the cold water tank 12 reaches the protection water level. When it is detected that the working time of the water supply pump 14 is greater than the second preset time length, and at the same time, it is detected that the water level in the cold water tank 12 reaches the high water level or the protection water level, the water supply pump 14 is controlled to be turned off. In this way, it can be prevented that the cold water tank 12 overflows and leaks due to failure of high water level detection.

In some embodiments, the second preset time length is greater than or equal to 3 minutes and the second preset time length is less than or equal to 6 minutes.

In this way, the cold water tank 12 can be prevented from overflowing and leaking.

Specifically, the second preset time is related to the capacity of the cold water tank 12, and the second preset time can be the working time of the water replenishment pump 14 to continuously work so that the cold water tank 12 can be replenished with a certain amount of water without causing the cold water tank 12 to overflow. In one embodiment, the second preset time is six minutes. That is, under the current capacity of the cold water tank 12, the water replenishment pump 14 can work for six minutes to make the water storage in the cold water tank 12 reach the high water level.

The second preset duration is greater than or equal to 3 minutes and the second preset duration is less than or equal to 6 minutes. For example, the second preset duration can be 3 minutes, 3.5 minutes, 4 minutes, 4.5 minutes, 5 minutes, 5.5 minutes or 6 minutes, or other arbitrary values greater than or equal to 3 minutes and less than or equal to 6 minutes. If the second preset duration is lower than 3 minutes, the water level in the cold water tank 12 may not yet reach the high water level, and may not be a fault condition at this time, so a fault misjudgment may occur. If the second preset duration is higher than 6 minutes, it may cause the water in the cold water tank 12 to overflow when the water level detection fails.

In certain embodiments, the control method comprises:

During the process of controlling the water replenishment pump 14 to start replenishing water from the clean water tank 10 to the cold water tank 12, when it is detected that the working time of the water replenishment pump 14 is greater than the second preset time and the water level in the cold water tank 12 is not higher than the high water level or the protection water level, a water replenishment fault alarm message is issued and the water treatment equipment 200 is controlled to stop working.

In this way, when a water level detection failure occurs in the cold water tank 12, the water treatment device 200 can be promptly controlled to stop working, thereby avoiding potential safety hazards caused by the water treatment device 200 working when the cold water tank 12 overflows or leaks.

Specifically, when the working time of the water replenishment pump 14 reaches the second preset time, it can be considered that the water storage in the cold water tank 12 has reached the high water level. If the signal that the water storage in the cold water tank 12 has reached the high water level is not detected at this time, it means that the current high water level detection fails, or the cold water tank 12 leaks. At this time, the water replenishment pump 14 is controlled to stop replenishing water, and the water treatment equipment 200 is controlled to stop working and send a water replenishment failure alarm message.

The water treatment device 200 may stop working by putting the water treatment device 200 into a power-off state, or shutting down various functional modules of the water treatment device 200 .

In this way, the water treatment device 200 can be prevented from operating when water overflows from the cold water tank 12 or the cold water tank 12 leaks, thereby effectively protecting the water treatment device 200 and extending the service life of the water treatment device 200.

In some embodiments, the water treatment device 200 includes three water level sensors, which are disposed in the cold water tank 12 , and the positions of the three water level sensors correspond to a low water level, a high water level, and a protection water level, respectively.

In this way, the low water level, high water level and protection water level of the cold water tank 12 can be detected respectively by the water level sensor.

Specifically, as shown in Fig. 2, the water level sensors at the low water level, high water level and protection water level are respectively the first water level sensor 16, the second water level sensor 18 and the third water level sensor 20. The water level sensors are respectively arranged at the corresponding low water level, high water level and protection water level in the cold water tank 12, so that the water level in the cold water tank 12 can be detected when reaching the low water level, high water level and protection water level, so that it can be judged whether it is necessary to add water to the cold water tank 12 according to the water storage in the cold water tank 12.

In one embodiment, the water level sensor includes a float sensor. Three float sensors are arranged at corresponding low water level, high water level and protection water level positions in the cold water tank 12. When the water in the cold water tank 12 does not contact the float, the float sinks. When the water in the cold water tank 12 is above the float, the float rises due to the buoyancy. Thus, by detecting whether the float at each position rises, it can be determined whether the water level in the cold water tank 12 reaches the position. For example, a reed tube is provided inside the float sensor. When the float rises, the reed tube inside the float sensor is triggered, and an electrical signal can be sent out. Thus, after the electrical signal sent out by the float sensor is recognized, it indicates that the water level in the cold water tank 12 has reached the corresponding position.

In some embodiments, the water treatment device 200 includes a water level sensor, which is disposed in the clean water tank 10. The water level sensor is used to obtain the water level in the clean water tank 10. The control method includes:

When the water level in the clean water tank 10 is lower than a preset height, the water replenishment pump 14 is controlled to be turned off so that the clean water tank 10 stops replenishing water to the cold water tank 12 .

In this way, it is possible to avoid the water replenishment pump 14 from operating when the water storage amount in the clean water tank 10 is insufficient.

Specifically, a water level sensor is provided in the clean water tank 10 to detect the amount of water stored in the clean water tank 10. In one embodiment, the clean water tank 10 is provided with a high water level and a low water level, and water level sensors are provided at the high water level and the low water level, respectively. As shown in FIG2 , the water level sensors at the low water level and the high water level are the fourth water level sensor 22 and the fifth water level sensor 24, respectively.

The preset height may be the water level corresponding to the low water level of the clean water tank 10. Thus, when the water level in the clean water tank 10 is lower than the preset height, it indicates that the clean water tank 10 is short of water, and the water replenishment pump 14 is controlled to be turned off at this time, so as to avoid the water replenishment pump 14 running idle and damaging the water replenishment pump 14, thereby extending the service life of the water treatment device 200.

Please refer to Figure 7. A control device 100 of a water treatment device 200 according to an embodiment of the present invention includes a processor 28 and a memory 30. The memory 30 stores a computer program. When the computer program is executed by the processor 28, it implements the control method of the water treatment device 200 of any of the above embodiments.

The control device 100 of the water treatment equipment 200 sets a protective water level higher than the high water level. During the water replenishment process, when it is detected that the water level of the cold water tank 12 exceeds the protective water level, the water replenishment pump 14 is controlled to be closed, thereby preventing the cold water tank 12 from overflowing or leaking to a certain extent, and effectively protecting the water treatment equipment 200.

Specifically, in one embodiment, the control device 100 includes a display panel, a control panel and an instant hot plate. The display panel is used for processing touch buttons, controlling the display UI and controlling the main logic of the machine. The control panel is used for processing sensor signals and controlling loads. The control panel includes a processor 28 and a memory 30. The instant hot plate is used to control the heating of water and control the output of hot water or normal temperature water. The display panel and the control panel are connected via a serial port, and the display panel and the instant hot plate are connected via a serial port to transmit and communicate data.

A computer-readable storage medium according to an embodiment of the present invention stores a computer program, and when the computer program is executed by the processor 28, the steps of the control method of the water treatment device 200 according to any of the above embodiments are implemented.

For example, when the computer program is executed by the processor 28, the control method of the water treatment device 200 implemented includes:

Step S101: in the process of controlling the water supply pump 14 to start so that the clean water tank 10 supplies water to the cold water tank 12, when it is detected that the water level of the cold water tank 12 exceeds the protection water level, the water supply pump 14 is controlled to be turned off.

In the above-mentioned computer-readable storage medium, by setting a protective water level higher than the high water level, during the water replenishment process, when it is detected that the water level of the cold water tank 12 exceeds the protective water level, the water replenishment pump 14 is controlled to be closed, thereby preventing the cold water tank 12 from overflowing and leaking to a certain extent, and effectively protecting the water treatment equipment 200.
