Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

This application discloses a dehumidifier control method. The method collects the water level value of the water tank in the dehumidifier, and controls the rotation speed of the water pump and the rotation speed of the compressor based on the water level value, so that the dehumidifier can maintain the dehumidification state for a long time. status, thus continuously providing users with a dry environment.

Specifically, referring to Figure 1, the dehumidifier control method disclosed in the embodiment of the present application includes:

Step S101: Obtain the water level value of the dehumidifier water tank.

During operation, the dehumidifier will condense the moisture in the air into water droplets, and these water droplets will flow into the water tank. If the water in the water tank cannot be discharged in time, the water level in the water tank will continue to rise. Through the pre-configured water level sensor in the water tank The water level in the water tank can be monitored in real time.

Step S102: Obtain the target speed of the water pump and the target speed of the compressor that are adapted to the water level value.

In this solution, the water level value is pre-configured to match the water pump speed and the compressor speed. Based on the detected water level values, the water pump and the compressor are controlled to work at different speeds.

Step S103: Adjust the speeds of the water pump and the compressor based on the target speed of the water pump and the target speed of the compressor.

After obtaining the target speed of the water pump and the target speed of the compressor that are suitable for the water level in the water tank, the current speed of the water pump is adjusted based on the target speed of the water pump, and the current speed of the compressor is adjusted based on the target speed of the compressor. The rotation speed enables the rotation speed of the water pump and compressor to match the detected water level value, thereby realizing dynamic adjustment of the rotation speed of the water pump and compressor based on the water level in the water tank, so that the water in the water tank can be maintained within a safe range for a long time, so as to This enables the humidifier to work continuously for a long time.

In the existing technology, some technical solutions are to automatically open the water tank when the water in the water tank reaches the upper limit. This solution will cause the water to be stored in the water tank for a long time if the water level in the water tank has not reached the upper limit. , if the dehumidifier is stopped using, it will take a long time to evaporate the water in the water tank. During this period of time, the problem of breeding bacteria in the water tank will easily occur. In this application, based on the water level value control in the water tank The speed of the water pump prevents excessive water from being stored in the water tank for a long time. If the dehumidifier is shut down, the water in the water tank will evaporate in a short period of time, thus preventing the problem of bacteria breeding in the water tank.

The water level value of the water tank can be set to multiple preset water level values. When the water level value reaches the corresponding preset water level value, the water pump target speed and compressor target that are adapted to the preset water level value are obtained. Rotating speed. For example, the target water level value may include a first-level water level value, a second-level water level value, and a third-level water level value. After the humidifier is turned on, when the compressor of the humidifier receives a dehumidification demand, the controller of the humidifier controls the compressor to run at the preset highest frequency, thereby quickly responding to the on-site environment. Dehumidification, when the dehumidifier runs for a period of time, the condensed water on the evaporator surface flows to the water tank, and the water level in the water tank will continue to rise. When the water level in the water tank reaches the first-level water level value, it means that the water level is high. If the humidifier is compressed When the machine runs at the current higher frequency, the water level in the water tank will rise rapidly or even become full. After detecting that the water level in the water tank reaches the first-level water level value, a signal will be generated to control the compressor drop speed. Frequency control signal. After the frequency is reduced, the rotation speed of the compressor will decrease accordingly. After the compressor frequency is reduced, the amount of water droplets condensed in the dehumidifier will decrease. At this time, the water level in the water tank will rise at a faster rate. will decrease, and at the same time, obtain the rotation speed of the water pump that matches the first-level water level value, and control the water pump to run at this rotation speed, thereby reducing the condensation speed of water droplets and at the same time using the water pump to discharge the water in the water tank, thereby Try to keep the increase speed of the water in the water tank balanced with the discharge speed. If the humidity in the environment is low and the drainage speed of the water pump is greater than the condensation speed of water droplets, the water level in the water tank will continue to decrease. When it drops below the preset low threshold, just turn off the water pump and release the speed control of the compressor based on the water level. When the speed control of the compressor based on the water level is released, the compressor The rotation speed can still be controlled by the ambient humidity value. If the humidity in the environment is too high, the drainage speed of the water pump may be lower than the condensation speed of water droplets. At this time, the water level in the water tank will continue to rise. Continue to monitor the water level value in the water tank. If When it is detected that the water level in the water tank reaches the secondary water level value, a control signal is generated again to control the frequency reduction of the compressor. The rotation speed of the compressor will be further reduced, and the amount of condensed water droplets in the dehumidifier will be further reduced. , at this time, the rising speed of the water level in the water tank will further decrease. At the same time, the rotation speed of the water pump that matches the secondary water level value is obtained, and the water pump is controlled to run at this rotation speed, thereby further reducing the flow rate of the water droplets. The condensation speed is increased at the same time as the drainage speed of the water pump. When it is detected again that the water level in the water tank reaches the first-level water level, the water pump and compressor are controlled based on the water pump speed and compressor speed that are suitable for the first-level water level. If it is detected When the number in the water tank further increases and reaches the third level water level value, it indicates that the water tank is about to be full of water, the compressor is controlled to stop, and the water pump is controlled to drain water at the highest speed.

Specifically, the above step S102 includes:

Step S201: Determine whether the water level value reaches the first-level water level value, and if so, execute step S202;

Step S202: Determine whether the water level value reaches the secondary water level value. If not, execute step S203; otherwise, execute step S204;

Step S203: When it is detected that the water level value of the water tank reaches the first-level water level value but does not reach the second-level water level value, obtain the first water pump speed and the first compressor speed that are adapted to the first-level water level;

Step S204: Determine whether the water level value reaches the third-level water level value. If not, execute step S205; otherwise, execute step S206;

Step S205: When it is detected that the water level value of the water tank reaches the second-level water level value but does not reach the third-level water level value, obtain the second water pump speed and the second compressor speed that are adapted to the second-level water level;

Step S206: When it is detected that the water level value of the water tank reaches the third-level water level value, obtain the third water pump speed and the third compressor speed that are adapted to the third-level water level.

Wherein, the first-level water level value < the second-level water level value < the third-level water level value, the first water pump speed < the second water pump speed < the third water pump speed, the first compressor speed > the second compressor speed > Third compressor speed.

In the technical solution disclosed in an embodiment of the present application, the corresponding water pump speed can be configured according to the rising speed of the water level in the water tank. Specifically, when obtaining the water pump speed that matches the water level value, it can be based on the previous Based on the water level changes obtained during the time period, the rising speed of the water level in the water tank during the time period is calculated, and then the rotational speed value of the water pump adapted to the rising speed is obtained.

Specifically, in the above method, the first water pump speed that is adapted to the first-level water level is obtained. The specific process may include:

Taking the time when the water level value of the water tank rises to the first-level water level as the starting time, obtain the average rising speed of the water level in the preset time period before the water level value of the water tank rises to the first-level water level; use the first The preset relationship obtains the first water pump rotation speed that is adapted to the average rising speed of the water level. In this embodiment, the corresponding first water pump rotation speed is obtained based on the average rising speed of the water level in the water tank in the previous time period, so that the drainage speed of the water pump matches the rising speed of the water level in the water tank.

In the corresponding above method, obtaining the second water pump speed that is adapted to the secondary water level may specifically include:

Taking the time when the water level value of the water tank rises to the secondary water level as the starting time, obtain the average rising speed of the water level in the preset time period before the water level value of the water tank rises to the secondary water level; use the second The preset relationship obtains the second water pump rotation speed that is adapted to the average rising speed of the water level. speed; the reason why the second preset relationship is used to obtain the second water pump speed that is adapted to the average rising speed of the water level is because if the first preset relationship is still used to calculate the second water pump speed, it may lead to The calculated second water pump speed is lower than the first water pump speed. Therefore, the second preset relationship can be used to obtain the second water pump speed that is adapted to the average rising speed of the water level. Of course, in addition to directly calculating the second water pump speed, In addition to the rotation speed of the second water pump, the corresponding rotation speed increase value can also be calculated based on the mapping relationship between the average water level rise speed and the water pump rotation speed, and then the rotation speed of the first water pump can be corrected based on the rotation speed increase value , get the second water pump speed.

In the above method, obtaining the third water pump speed that is adapted to the third-level water level may specifically include:

Taking the time when the water level value of the water tank rises to the third-level water level as the starting time, obtain the average rising speed of the water level in the preset time period before the water level value of the water tank rises to the third-level water level; use the third level The preset relationship obtains the third water pump rotation speed that is adapted to the average rising speed of the water level. In addition to directly calculating the rotation speed of the third water pump, the corresponding rotation speed increase value can also be calculated based on the mapping relationship between the average water level rise speed and the water pump rotation speed, and then the rotation speed increase value can be calculated based on the rotation speed increase value. The speed of the second water pump is corrected to obtain the speed of the third water pump.

In the technical solution disclosed in another embodiment of the present application, considering that during the dehumidification process of the dehumidifier, the air humidity value in the environment decreases, therefore, the amount of water droplets condensed in the dehumidifier gradually decreases. , therefore, in this solution, the change of water level in the next period of time can be predicted based on the change of water level obtained in the previous period of time, and the change of water level in the next period of time can be calculated based on the change of water level in the next period of time. The average rising speed of the water level in the water tank during the time period, and then obtain the rotational speed value of the water pump that is adapted to the rising speed.

Specifically, in this embodiment,

Obtaining the first water pump speed that is suitable for the first-level water level includes:

Taking the time when the water level value of the water tank rises to the third-level water level as the starting time, obtain the water level rising speed at each time node in the preset time period before the water level value of the water tank rises to the third-level water level, Based on the water level rising speed at each time node, predict the third average water level rising speed in the next preset time period starting when the water level value of the water tank rises to the third-level water level, and obtain the corresponding The rotation speed increase value that matches the third average water level rising speed, and the second water pump rotation speed is corrected based on the rotation speed increase value to obtain the third water pump rotation speed;

In the above scheme, after calculating the rising speed of the water level in the water tank at each time node in the previous period, the relationship function between the water level rising speed and time can be constructed based on the water level rising speed of these nodes. Based on this relationship function, Predict the rising speed of the water level at each time node in the next period of time, and then calculate the average of the rising speed of the water level in the time period based on the predicted rising speed of the water level at each time node, and then calculate the corresponding third A water pump speed or the corresponding rotation speed increase value. This achieves precise control of the water pump speed based on the rising speed of the water level.

In the technical solutions disclosed in the embodiments of this application, in order to drain the water tank in time to prevent the water in the water tank from overflowing, the priority of the technical solution of controlling the rotation speed of the compressor based on the water level in the water tank is higher than that in the normal state. The priority of the compressor speed control scheme under normal conditions may refer to the compressor speed control scheme in the prior art, for example, the control scheme is based on the ambient humidity value and the set target humidity value. The technical solution is a technical solution for controlling the rotation speed value of the compressor; or a technical solution for controlling the rotation speed value of the compressor based on a preset gear. That is to say, when the water level value of the water tank is less than the first-level water level value or the minimum value of the preset water level values, the rotation speed value of the compressor is controlled based on the ambient humidity value and the set target humidity value.

In the technical solution disclosed in another embodiment of the present application, a maximum water level threshold can also be set. The maximum water level threshold can refer to the maximum value of the water level allowed by the water tank. When the water level in the water tank reaches the maximum water level threshold, At this time, the rotation speed of the water pump is controlled to reach the maximum, and at the same time, the compressor is controlled to stop, thereby quickly draining the water in the water tank.

In the technical solution disclosed in the embodiment of the present application, when the water level in the water tank drops from above the third-level water level value to below the third-level water level value, or from above the second-level water level value to below the second-level water level value, it can continue to be maintained. The water pump speed and compressor speed may be changed, or the compressor speed and water pump speed adjustment value may be the compressor speed and water pump speed corresponding to the last recorded second-level water level value and the first-level water level value.

That is, in the above scheme, when the compressor speed and water pump speed corresponding to the first-level water level value, the second-level water level value and the third-level water level value are calculated, these speed values can be recorded in the preset list. When the When the water level value drops from above the third-level water level value to below the third-level water level value, the compressor and water pump are controlled based on the compressor speed and water pump speed corresponding to the recorded second-level water level value. When the water level value decreases from the second-level water level value to When the above water level value drops below the second-level water level value, the compressor and water pump are controlled based on the compressor speed and water pump speed corresponding to the recorded first-level water level value. When the water level value drops from above the third-level water level value to the third-level water level value below, release the control of the compressor and water pump based on the water level value.
