Description

Technical Field

[0001] This invention relates to the field of intelligent device technology, specifically to a dehumidifier control method, device, equipment, and dehumidifier. Background Technology

[0002] A dehumidifier, also known as a dehumidifier machine, is a small member of the refrigeration and air conditioning system. When working, a dehumidifier condenses moisture in the air into water droplets, which flow into a water tank. The water tank is usually equipped with a water level sensor to monitor the water level. When the water level reaches a certain height, the controller will either shut off the compressor and sound an alarm to remind the user that the tank is full, or start the water pump to drain the water. This prevents the dehumidifier from continuously providing a dry environment for an extended period. Summary of the Invention

[0058] Figure 4 This is a schematic diagram of the structure of the dehumidifier control device disclosed in the embodiments of this application. Detailed Implementation

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] This application discloses a dehumidifier control method. The method collects the water level value of the water tank in the dehumidifier and controls the speed of the water pump and the speed of the compressor based on the water level value, so that the dehumidifier can maintain the dehumidification state for a long time and continuously provide a dry environment for users.

[0061] For details, see Figure 1 The dehumidifier control method disclosed in this application includes:

[0062] Step S101: Obtain the water level value of the dehumidifier water tank.

[0063] When a dehumidifier is working, it condenses the moisture in the air into water droplets. These droplets flow into the water tank. If the water in the tank cannot be drained in time, the water level in the tank will continue to rise. The water level in the tank can be monitored in real time by a water level sensor that is pre-installed in the tank.

[0064] Step S102: Obtain the target speed of the water pump and the target speed of the compressor that are compatible with the water level value.

[0065] In this scheme, the water level value is pre-configured to match the water pump speed and compressor speed. Based on the different detected water level values, the water pump and compressor are controlled to operate at different speeds.

[0066] Step S103: Adjust the speed of the water pump and the compressor based on the target speed of the water pump and the target speed of the compressor.

[0067] Once the target speeds of the water pump and compressor, which are compatible with the water level in the tank, are obtained, the current speed of the water pump is adjusted based on the target speed, and the current speed of the compressor is adjusted based on the target speed. This ensures that the speeds of the water pump and compressor are compatible with the detected water level, thereby achieving dynamic adjustment of the speeds of the water pump and compressor based on the water level in the tank. This keeps the water in the tank within a safe range for a long time, allowing the humidifier to work continuously for extended periods.

[0068] In existing technologies, some solutions automatically open the water tank when the water level reaches its upper limit. However, this can lead to water remaining in the tank for an extended period if the water level does not reach the upper limit. If the dehumidifier stops operating, it can take a considerable amount of time for the water to evaporate, during which time bacteria can easily grow in the tank. In this application, the pump speed is controlled based on the water level in the tank, preventing excessive water from remaining in the tank for extended periods. If the dehumidifier stops operating, the water in the tank will evaporate quickly, thus preventing the growth of bacteria in the tank.

[0069] The water level in the water tank can be set to multiple preset water level values. When the water level reaches the corresponding preset water level value, the target speed of the water pump and the target speed of the compressor, which are adapted to the preset water level value, are obtained. 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 a preset maximum frequency, thereby quickly dehumidifying the environment. After the dehumidifier runs for a period of time, the condensed water on the surface of the evaporator flows into 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 indicates that the water level is high. If the compressor of the humidifier continues to run at the current high frequency, the water level in the water tank will rise rapidly or even fill up. After detecting that the water level in the water tank has reached the first-level water level value, a control signal is generated to control the compressor to reduce its frequency. After the frequency is reduced, the speed of the compressor will decrease accordingly. After the compressor frequency is reduced, the amount of water droplets condensed in the dehumidifier will decrease. When the water level in the tank is reduced, the rate of increase in water level will decrease. At the same time, the pump speed matching the first-level water level value is obtained, and the pump is controlled to operate at this speed. This reduces the condensation rate of water droplets while pumping water out of the tank, thus keeping the rate of increase and discharge of water in the tank as balanced as possible. If the ambient humidity is low and the pump's drainage rate is greater than the condensation rate of water droplets, the water level in the tank will continue to decrease. When it decreases to a preset low threshold, the pump is turned off, and the speed control of the compressor based on the water level is released. When the speed control of the compressor based on the water level is released, the compressor 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 less than the condensation speed of the water droplets. In this case, the water level in the tank will continue to rise. The water level in the tank will continue to be monitored. If the water level in the tank reaches the secondary water level, a control signal for controlling the compressor to reduce its frequency will be generated again. The speed of the compressor will be further reduced, and the amount of water droplets condensed in the dehumidifier will be further reduced. At this time, the rising speed of the water level in the tank will be further reduced. At the same time, the speed of the water pump that matches the secondary water level is obtained, and the water pump is controlled to run at this speed, thereby further reducing the condensation speed of the water droplets while increasing the drainage speed of the water pump. When the water level in the tank reaches the primary water level again, the water pump and compressor are controlled based on the water pump speed and compressor speed that match the primary water level. If the water level in the tank rises further and reaches the tertiary water level, it indicates that the water tank is about to be full. The compressor is stopped, and the water pump is controlled to drain water at the highest speed.

[0070] Specifically, step S102 above includes:

[0071] Step S201: Determine whether the water level has reached the first-level water level. If so, proceed to step S202.

[0072] Step S202: Determine whether the water level has reached the secondary water level. If not, proceed to step S203; otherwise, proceed to step S204.

[0073] Step S203: When the water level in the water tank is detected to have reached the first-level water level but not the second-level water level, the first water pump speed and the first compressor speed that are compatible with the first-level water level are obtained.

[0074] Step S204: Determine whether the water level has reached the level of a third-level water level. If not, proceed to step S205; otherwise, proceed to step S206.

[0075] Step S205: When the water level in the water tank is detected to have reached the secondary water level but not the tertiary water level, the second water pump speed and the second compressor speed that are compatible with the secondary water level are obtained.

[0076] Step S206: When the water level in the water tank is detected to reach the third level, the speed of the third water pump and the speed of the third compressor that are adapted to the third level are obtained.

[0077] 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, and the first compressor speed > the second compressor speed > the third compressor speed.

[0078] In one embodiment of the technical solution disclosed in this application, the pump speed can be configured according to the rising speed of the water level in the tank. Specifically, when obtaining the pump speed that matches the water level value, the rising speed of the water level in the tank during the previous time period can be calculated based on the water level change obtained in the previous time period, and then the pump speed value that matches the rising speed can be obtained.

[0079] Specifically, in the above method, obtaining the first pump speed adapted to the first-stage water level can include the following process:

[0080] Taking the moment when the water level in the tank rises to the first-level water level as the starting point, the average rate of water level rise during a preset time period before the water level reaches the first-level water level is obtained; a first pump speed adapted to the average rate of water level rise is obtained using a first preset relationship. In this embodiment, the first pump speed is obtained based on the average rate of water level rise in the tank during the previous time period, so that the pump's drainage speed is adapted to the rate of water level rise in the tank.

[0081] In the corresponding method described above, obtaining the second pump speed adapted to the secondary water level can specifically include:

[0082] Taking the rise of the water level in the water tank to the secondary water level as the starting time, the average rate of rise of the water level during a preset time period before the water level rises to the secondary water level is obtained; a second preset relationship is used to obtain a second pump speed that matches the average rate of rise of the water level. The reason for using the second preset relationship to obtain the second pump speed that matches the average rate of rise of the water level is that if the first preset relationship is still used to calculate the second pump speed, the calculated second pump speed may be lower than the first pump speed. Therefore, the second preset relationship can be used to obtain the second pump speed that matches the average rate of rise of the water level. Of course, in addition to directly calculating the second pump speed, the corresponding speed increase value can also be calculated based on the mapping relationship between the average rate of rise of the water level and the increase of the pump speed. Then, the first pump speed is corrected based on the speed increase value to obtain the second pump speed.

[0083] In the above method, obtaining the third pump speed adapted to the three-stage water level can specifically include:

[0084] Starting from the moment when the water level in the tank rises to the third level, the average rate of water level rise during a preset time period before the water level reaches the third level is obtained. A third preset relationship is used to obtain a third pump speed that matches the average rate of water level rise. Besides directly calculating the third pump speed, the corresponding speed increase can be calculated based on the mapping relationship between the average rate of water level rise and the pump speed increase. The second pump speed is then corrected based on this speed increase to obtain the third pump speed.

[0085] In another embodiment of the technical solution disclosed in this application, considering that the air humidity value in the environment decreases during the dehumidification process of the dehumidifier, the amount of water droplets condensed in the dehumidifier gradually decreases. Therefore, in this solution, the water level change in the next period can be predicted based on the water level change obtained in the previous period. The average rising rate of the water level in the tank in the next period can be calculated based on the water level change in the next period, and then the rotational speed of the water pump adapted to the rising rate can be obtained.

[0086] Specifically, in this embodiment,

[0087] Obtaining the first pump speed adapted to the first-level water level includes:

[0088] Taking the water level in the water tank rising to the first-level water level as the starting time, the water level rise rate at each time node within a preset time period before the water level in the water tank rises to the first-level water level is obtained. Based on the water level rise rate at each time node, the first average water level rise rate within the next preset time period starting from the water level in the water tank rising to the first-level water level is predicted, and a first water pump speed adapted to the first average water level rise rate is obtained.

[0089] Obtaining the second pump speed adapted to the secondary water level includes:

[0090] Taking the rise of the water level in the water tank to the secondary water level as the starting time, the water level rise rate at each time node within a preset time period before the water level in the water tank rises to the secondary water level is obtained. Based on the water level rise rate at each time node, the second average water level rise rate within the next preset time period starting from the rise of the water level in the water tank to the secondary water level is predicted. The rotation speed increase value that matches the second average water level rise rate is obtained. Based on the rotation speed increase value, the rotation speed of the first water pump is corrected to obtain the rotation speed of the second water pump.

[0091] Obtaining the third pump speed adapted to the three-stage water levels includes:

[0092] Taking the water level in the tank rising to the third level as the starting time, the water level rise rate at each time node within a preset time period before the water level in the tank rises to the third level is obtained. Based on the water level rise rate at each time node, the third average water level rise rate within the next preset time period starting from the water level in the tank rising to the third level is predicted. The rotation speed increase value that matches the third average water level rise rate is obtained. Based on the rotation speed increase value, the rotation speed of the second water pump is corrected to obtain the third water pump rotation speed.

[0093] In the above scheme, after calculating the rate of water level rise in the tank at each time point within a previous period, a relationship function between the water level rise rate and time can be constructed based on these rates. This function can then be used to predict the water level rise rate at each time point in the next period. Furthermore, based on the predicted water level rise rates at each time point, the average rate of water level rise within that time period is calculated, thus yielding the corresponding first pump speed or the corresponding increase in pump speed. This achieves precise control of the pump speed based on the water level rise rate.

[0094] In the technical solutions disclosed in this application, to promptly drain the water tank and prevent overflow, the priority of controlling the compressor speed based on the water level in the tank is higher than the priority of the compressor speed control scheme under normal conditions. The compressor speed control scheme under normal conditions can refer to existing compressor speed control schemes, such as those controlling the compressor speed based on ambient humidity and a set target humidity value; or those controlling the compressor speed based on a preset level. That is, when the water level in the tank is lower than a first-level water level or the minimum of the preset water level values, the compressor speed is controlled based on the ambient humidity and the set target humidity value.

[0095] In another embodiment of the technical solution disclosed in this application, a maximum water level threshold can also be set. The maximum water level threshold can refer to the highest value of the water level allowed by the water tank. When the water level in the water tank reaches the maximum water level threshold, the speed of the water pump is controlled to reach the maximum, and at the same time, the compressor is controlled to stop, thereby quickly discharging the water in the water tank.

[0096] In the technical solution disclosed in the embodiments of this application, when the water level in the water tank drops from above the third level to below the third level, or from above the second level to below the second level, the pump speed and compressor speed can be maintained, or the compressor speed and pump speed can be adjusted to the compressor speed and pump speed corresponding to the second level and first level water level values ​​recorded in the previous record.

[0097] That is, in the above scheme, when the compressor speed and water pump speed corresponding to the first-level water level, second-level water level, and third-level water level are calculated, these speed values ​​can be recorded in a preset list. When the water level drops from above the third-level water level to below the third-level water level, the compressor and water pump are controlled based on the recorded compressor speed and water pump speed corresponding to the second-level water level. When the water level drops from above the second-level water level to below the second-level water level, the compressor and water pump are controlled based on the recorded compressor speed and water pump speed corresponding to the first-level water level. When the water level drops from above the third-level water level to below the third-level water level, the control of the compressor and water pump based on the water level is released.
