Description

Technical Field

[0001] The present application relates to the field of environmental monitoring, and more specifically, to a dehumidifier control method and device, a dehumidifier, and a computer-readable storage medium. Background Art

[0002] The dehumidifier in the related art uses a desiccant coated on a rotating wheel to physically absorb moisture in the air, and through its own slow rotation, a heater heats and vaporizes the moisture, so that the desiccant is dehydrated, regenerated, and reused.

[0003] Some dehumidifiers can not only dehumidify but also adjust the indoor temperature. However, the dehumidifiers in the related art consume a large amount of power when adjusting the indoor temperature. Summary of the invention

[0004] The purpose of the present application is to provide a dehumidifier control method and device, a dehumidifier and a computer-readable storage medium, which can reduce the power consumption of the dehumidifier when adjusting the indoor temperature.

[0005] In a first aspect, an embodiment of the present application provides a dehumidifier control method, wherein the dehumidifier includes a processing fan, and the dehumidifier control method includes: obtaining the spatial temperature of the target space; determining whether the spatial temperature exceeds a first set temperature range for a set time; if the spatial temperature exceeds the first set temperature range for the set time, adjusting the fan frequency of the processing fan.

[0006] Compared with the related art, in the dehumidifier control method provided in the embodiment of the present application, when the space temperature exceeds the first set temperature range for a set time, the fan frequency of the processing fan is adjusted. The change in fan frequency can change the wind speed of the dehumidifier in delivering fresh air to the target space, thereby regulating the temperature in the target space. By setting the set time, the fan frequency of the processing fan can be reduced due to frequent changes in temperature fluctuations. Since the sudden change process of the fan frequency may generate a large induced current, resulting in increased energy consumption, reducing the frequent changes in the fan frequency of the processing fan due to temperature fluctuations can effectively reduce the energy consumption in the temperature regulation process.

[0007] In an optional embodiment, the first set temperature range is greater than the first set temperature; if the space temperature exceeds the first set temperature range for the set time, adjusting the fan frequency of the processing fan includes: if the space temperature is less than or equal to the first set temperature for the set time, reducing the fan frequency of the processing fan. If the space temperature is less than or equal to the first set temperature for the set time, it means that the space temperature in the target space is maintained at a low state for a long time. At this time, reducing the fan frequency of the processing fan can reduce the wind speed of the dehumidifier to send fresh air into the target space, reducing the possibility of further reduction of the space temperature in the target space; in addition, reducing the fan frequency of the processing fan can also effectively reduce the power of the dehumidifier and reduce the energy consumption of the dehumidifier.

[0008] In an optional embodiment, the first set temperature range is less than the second set temperature; if the space temperature exceeds the first set temperature range for the set time, adjusting the fan frequency of the processing fan includes: if the space temperature is greater than or equal to the second set temperature for the set time, increasing the fan frequency of the processing fan. If the space temperature is greater than or equal to the second set temperature for the set time, it means that the space temperature in the target space is maintained at a high state for a long time. At this time, increasing the fan frequency of the processing fan can increase the wind speed of the dehumidifier to send fresh air into the target space, and cool down the space temperature in the target space more quickly.

[0009] In an optional embodiment, the dehumidifier includes a surface cooler, and the dehumidifier control method further includes: determining whether the space temperature exceeds a second set temperature range, the second set temperature range being different from the first set temperature range; if the space temperature exceeds the second set temperature range, adjusting the opening of the electric proportional valve of the surface cooler. When the space temperature exceeds the second set temperature range, adjusting the opening of the electric proportional valve of the surface cooler can also play a role in regulating the space temperature. Combined with the adjustment of the fan frequency within the first set temperature range, it can have a better effect on regulating the space temperature of the target space.

[0010] In an optional embodiment, the second set temperature range is greater than the third set temperature, the first set temperature range is greater than the first set temperature; the third set temperature is less than the first set temperature, and the difference between the third set temperature and the first set temperature is greater than or equal to 0.3°C and less than or equal to 0.7°C. By setting the third set temperature to be less than the first set temperature, the possibility of the space temperature falling below the third set temperature can be reduced by adjusting the fan frequency when the space temperature is maintained near the third set temperature for a long time, thereby reducing the energy consumption of the dehumidifier. By setting the difference between the third set temperature and the first set temperature to be greater than or equal to 0.3°C, the problem of difficulty in triggering the adjustment of the fan frequency due to too small a difference can be reduced, while by setting the difference between the third set temperature and the first set temperature to be less than or equal to 0.7°C, the problem of frequent triggering of the adjustment of the fan frequency due to too large a difference can be reduced.

[0011] In an optional embodiment, the second set temperature range is less than the fourth set temperature, and the first set temperature range is less than the second set temperature; the fourth set temperature is greater than the second set temperature, and the difference between the fourth set temperature and the second set temperature is greater than or equal to 0.3°C and less than or equal to 0.7°C. By setting the fourth set temperature greater than the second set temperature, when the space temperature is maintained near the fourth set temperature for a long time, the possibility of the space temperature rising above the fourth set temperature can be reduced by adjusting the fan frequency, thereby reducing the energy consumption of the dehumidifier. By setting the difference between the fourth set temperature and the second set temperature to be greater than or equal to 0.3°C, the problem of difficulty in triggering the adjustment of the fan frequency due to the small difference can be reduced, while by setting the difference between the fourth set temperature and the second set temperature to be less than or equal to 0.7°C, the problem of frequent triggering of the adjustment of the fan frequency due to the large difference can be reduced.

[0012] In an optional embodiment, the dehumidifier control method further includes: displaying the fan frequency of the processing fan in real time. Displaying the fan frequency of the processing fan in real time can facilitate the staff to judge whether the processing fan is faulty when the indoor temperature is abnormal.

[0013] In the second aspect, an embodiment of the present application provides a dehumidifier, comprising: a fresh air inlet and a fresh air outlet, and a rotor and a processing fan arranged between the fresh air inlet and the fresh air outlet, wherein a desiccant is arranged in the rotor, and the rotor comprises a drying zone and a regeneration zone, the drying zone is arranged between the fresh air inlet and the fresh air outlet, and the air outlet direction of the processing fan is toward the drying zone; a temperature sensor, wherein the temperature sensor is arranged in a target space and is used to measure and obtain the spatial temperature of the target space; a control device, wherein the control device is used to obtain the spatial temperature, determine whether the spatial temperature exceeds a first set temperature range for a set time, and when the spatial temperature exceeds the first set temperature range for the set time, adjust the fan frequency of the processing fan.

[0014] Compared with the related art, in the dehumidifier provided in the embodiment of the present application, when the control device determines that the space temperature exceeds the first set temperature range for a set time, it controls and adjusts the fan frequency of the processing fan. The change of the fan frequency can change the wind speed of the dehumidifier to deliver fresh air to the target space, thereby regulating the temperature in the target space. By setting the set time, the frequent changes in the fan frequency of the processing fan due to temperature fluctuations can be reduced. Since the sudden change process of the fan frequency may generate a large induced current, resulting in increased energy consumption, reducing the frequent changes in the fan frequency of the processing fan due to temperature fluctuations can effectively reduce the energy consumption in the temperature regulation process.

[0015] In an optional embodiment, the dehumidifier further includes: a surface cooler; the surface cooler is arranged between the fresh air inlet and the fresh air outlet; the control device is also used to determine whether the space temperature exceeds a second set temperature range, the second set temperature range is different from the first set temperature range, and when the space temperature exceeds the second set temperature range, the electric proportional valve opening of the surface cooler is adjusted. When the control device determines that the space temperature exceeds the second set temperature range, it controls and adjusts the electric proportional valve opening of the surface cooler, which can also play a role in regulating the space temperature. Combined with the adjustment of the fan frequency in the first set temperature range, it can have a better adjustment effect on the space temperature of the target space.

[0016] In an optional embodiment, the dehumidifier further includes: a return air inlet and a return air outlet; the return air inlet is connected to the target space, and the return air outlet is arranged between the process fan and the fresh air inlet. The return air inlet is connected to the target space, and the return air outlet is arranged between the process fan and the fresh air inlet. Adjusting the fan frequency of the process fan can adjust the air volume drawn from the target space by the process fan, thereby achieving a better adjustment effect on the spatial temperature of the target space.

[0017] In a third aspect, an embodiment of the present application provides a dehumidifier control device, wherein the dehumidifier includes a processing fan, and the dehumidifier control device includes: a communication module, wherein the communication module is used to obtain the spatial temperature of the target space; a judgment module, wherein the judgment module determines whether the spatial temperature remains within a first set temperature range for a set time period; and a control module, wherein the control module is used to adjust the fan frequency of the processing fan when the spatial temperature remains within the first set temperature range for the set time period.

[0018] Compared with the related art, in the dehumidifier control device provided in the embodiment of the present application, when the judgment module determines that the space temperature exceeds the first set temperature range for a set time, the control module controls and adjusts the fan frequency of the processing fan. The change in fan frequency can change the wind speed of the dehumidifier in delivering fresh air to the target space, thereby regulating the temperature in the target space. By setting the set time, the frequent changes in the fan frequency of the processing fan due to temperature fluctuations can be reduced. Since the sudden change process of the fan frequency may generate a large induced current, resulting in increased energy consumption, reducing the frequent changes in the fan frequency of the processing fan due to temperature fluctuations can effectively reduce the energy consumption in the temperature adjustment process.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0034] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0035] A dehumidifier is a device used to reduce the humidity in a space. It is widely used in industrial and agricultural production, medicine, electronics, food industry production and other departments and industries that have strict requirements on environmental humidity. There are many different types of dehumidifiers, such as Figure 1 The figure shows a schematic diagram of the structure of a rotary dehumidifier provided by an embodiment of the present application, including: a fresh air inlet 10 and a fresh air outlet 20, the fresh air inlet 10 and the fresh air outlet 20 are connected via a pipeline, a rotor 30 and a processing fan 40 are arranged between the fresh air inlet 10 and the fresh air outlet 20, the fresh air inlet 10 is arranged outdoors, and the fresh air outlet 20 is arranged in a target space such as a workshop, a warehouse, and a greenhouse, and a desiccant is arranged in the rotor 30. After the processing fan 40 is started, it will inhale air from the fresh air inlet 10 to form fresh air, and the fresh air will be dried by the desiccant in the rotor 30 and then enter the target space through the fresh air outlet 20. The dry fresh air with reduced humidity entering the target space can effectively reduce the ambient humidity in the target space, thereby achieving a dehumidification effect. In addition, the dehumidifier can also realize the reuse of desiccant, such as Figure 1 As shown, the dehumidifier further includes a regeneration air inlet 50 and a regeneration air outlet 60, and the regeneration air inlet 50 and the regeneration air outlet 60 can also be connected via a pipeline. In different types of dehumidifiers, the regeneration air inlet 50 can be as follows Figure 1 The connection shown is between the fresh air inlet 10 and the fresh air outlet 20, or it can be connected outdoors. The specific setting can be based on the actual usage scenario and dehumidifier model. Figure 1 After starting, the treatment fan 40 can also form an airflow in the pipeline between the regeneration air inlet 50 and the regeneration air outlet 60, that is, the regeneration air. The rotor 30 is also connected between the regeneration air inlet 50 and the regeneration air outlet 60. When the regeneration air passes through the rotor 30, it can take away the moisture in the desiccant in the rotor 30, so that the desiccant can be reused. In order to isolate the fresh air and the regeneration air, the rotor 30 can be divided into a drying area 31 and a regeneration area 32. The drying area 31 is set between the fresh air inlet 10 and the fresh air outlet 20, and the regeneration area 32 is set between the regeneration air inlet 50 and the regeneration air outlet 60. When the fresh air passes through the drying area 31, the desiccant in the drying area 31 absorbs the moisture in the fresh air, and the moisture content of the desiccant increases. As the wheel 30 rotates, the desiccant with increased moisture content rotates to the regeneration area 32. When the regeneration air passes through the regeneration area 32, it takes away the moisture in the desiccant, causing the moisture content of the desiccant to decrease. As the wheel 30 rotates, the desiccant with decreased moisture content rotates to the drying area 31 to absorb the moisture in the fresh air again. This cycle achieves the dehumidification effect of the target space. In addition, Figure 1As shown, a heater 70 may be provided between the regeneration air inlet 50 and the regeneration zone 32 . The heater 70 may heat the regeneration air. Increasing the temperature of the regeneration air may enhance the dehydration effect of the regeneration air on the desiccant in the regeneration zone 32 .

[0036] Since the dehumidifier needs to blow fresh air into the target space during the dehumidification process, by controlling the wind speed, temperature and other variables of the fresh air, the dehumidifier can not only regulate the humidity of the target space during operation, but also regulate the temperature in the target space. The embodiments of the present application provide a dehumidifier control method, device, and computer-readable storage medium, which can better regulate the temperature in the target space.

[0037] The dehumidifier control method provided in the embodiment of the present application can be applied in a variety of different scenarios. For example, in the application scenario of battery production, the dehumidifier controlled by the dehumidifier control method may be a dehumidifier in a battery production workshop or a battery storage warehouse; in the application scenario of automobile production, the dehumidifier controlled by the dehumidifier control method may be a dehumidifier in an automobile production workshop or an automobile storage warehouse; in the application scenario of agricultural production, the dehumidifier controlled by the dehumidifier control method may be a dehumidifier in an agricultural greenhouse or an agricultural product storage warehouse.

[0038] Please refer to Figure 2 , the embodiment of the present application provides a dehumidifier control method, such as Figure 2 As shown, the dehumidifier control method includes:

[0039] Step S101: Acquire the space temperature of the target space.

[0040] Step S102: Determine whether the space temperature exceeds a first set temperature range for a set time.

[0041] Step S103: When the space temperature exceeds the first set temperature range for a set time, the fan frequency of the processing fan is adjusted.

[0042] The target space is the space where the dehumidifier needs to adjust the air humidity and temperature. The target space may be different in different application scenarios. For example, in the application scenario of battery production, the target space may be a battery production workshop, a battery storage warehouse, etc.; in the application scenario of automobile production, the target space may be an automobile production workshop, an automobile storage warehouse, etc.; in the application scenario of agricultural production, the target space may be an agricultural greenhouse, an agricultural product storage warehouse, etc.

[0043] Acquiring the spatial temperature of the target space may, for example, involve setting a temperature sensor in the target space to measure the air temperature in the target space, and using the measurement result of the temperature sensor as the spatial temperature.

[0044] Specifically, in different embodiments of the present application, for example, a single temperature sensor may be set at a set position in the target space, and the measurement result of the temperature sensor may be directly used as the space temperature. Alternatively, temperature sensors may be set at multiple different positions in the target space to measure multiple air temperatures, and then the mean / median of the multiple air temperatures may be used as the space temperature.

[0045] The first set temperature range may be a temperature range pre-set before the dehumidifier starts to operate, or a temperature range set during the operation of the dehumidifier. For example, a human-computer interaction system may be set in the dehumidifier, and the user may set or modify the first set temperature range during the operation of the dehumidifier through the human-computer interaction system.

[0046] The set time can also be a time pre-set before the dehumidifier starts running, or a time set during the operation of the dehumidifier. For example, the user can also set or modify the set time during the operation of the dehumidifier through the human-computer interaction system.

[0047] In some embodiments of the present application, the fan frequency refers to the speed at which the fan rotates, usually expressed in revolutions per minute (RPM). In industrial applications, the frequency of the fan is usually controlled by the rotation speed of the motor. Therefore, the fan frequency can also be expressed as the frequency of the motor.

[0048] Furthermore, the determination of whether the space temperature exceeds the first set temperature range for a set time may specifically be, for example: starting timing when the space temperature exceeds the first set temperature range, and when the timing duration reaches the set duration, it is determined that the space temperature exceeds the first set temperature range for the set duration, and when the timing duration does not reach the set duration and the space temperature changes to not exceed the first set temperature range, it is determined that the space temperature exceeds the first set temperature range for less than the set time, and the timing duration is reset to zero, and the timing is restarted when the space temperature exceeds the first set temperature range once.

[0049] Compared with the related art, in the dehumidifier control method provided in the embodiment of the present application, when the space temperature exceeds the first set temperature range for a set time, the fan frequency of the processing fan is adjusted. The change in fan frequency can change the wind speed of the dehumidifier in delivering fresh air to the target space, thereby regulating the temperature in the target space. By setting the set time, the fan frequency of the processing fan can be reduced due to frequent changes in temperature fluctuations. Since the sudden change process of the fan frequency may generate a large induced current, resulting in increased energy consumption, reducing the frequent changes in the fan frequency of the processing fan due to temperature fluctuations can effectively reduce the energy consumption in the temperature regulation process.

[0050] In some embodiments of the present application, the first set temperature range may be greater than the first set temperature; if the space temperature exceeds the first set temperature range for a set time, the fan frequency of the processing fan is adjusted, including: if the space temperature is less than or equal to the first set temperature for a set time, the fan frequency of the processing fan is reduced.

[0051] The first set temperature can be flexibly set according to the actual application scenario. The first set temperature can also be a temperature preset before the dehumidifier starts running, or a temperature set or modified by the user through the human-computer interaction system during the operation of the dehumidifier.

[0052] If the space temperature is less than or equal to the first set temperature for the set time, it means that the space temperature in the target space is maintained at a low state for a long time. Corresponding to the actual application scenario, it may be that the heat dissipation of the heat source equipment in the target space is reduced. For example, when the target space is a battery production workshop, the battery production equipment in the workshop may be suspended and the heat dissipation is reduced. At this time, reducing the fan frequency of the processing fan can reduce the wind speed of the dehumidifier to send fresh air into the target space, reducing the possibility of further reduction in the space temperature in the target space; in addition, reducing the fan frequency of the processing fan can also effectively reduce the power of the dehumidifier and reduce the energy consumption of the dehumidifier.

[0053] In some embodiments of the present application, the first set temperature range is less than the second set temperature; if the space temperature exceeds the first set temperature range for a set time, the fan frequency of the processing fan is adjusted, including: if the space temperature is greater than or equal to the second set temperature for a set time, the fan frequency of the processing fan is increased.

[0054] The second set temperature can be flexibly set according to the actual application scenario. The second set temperature can also be a temperature preset before the dehumidifier starts running, or a temperature set or modified by the user through the human-computer interaction system during the operation of the dehumidifier.

[0055] If the space temperature is greater than or equal to the second set temperature for the set time, it means that the space temperature in the target space is maintained at a high state for a long time. Corresponding to the actual application scenario, it may be that the heat dissipation of the heat source equipment in the target space increases. For example, when the target space is a battery production workshop, the operating power of the battery production equipment in the workshop may be increased, resulting in increased heat dissipation. At this time, increasing the fan frequency of the processing fan can increase the wind speed of the dehumidifier to send fresh air into the target space, thereby cooling the space temperature in the target space more quickly.

[0056] In some other embodiments of the present application, please refer to Figure 3 , Figure 4 , Figure 3 Shown is a schematic diagram of the structure of a dehumidifier provided in some other embodiments of the present application. Figure 4 FIG. 1 is a flow chart of a dehumidifier control method provided by some other embodiments of the present application. Figure 3 As shown, the dehumidifier may further include a surface cooler 70, which is disposed between the fresh air inlet 10 and the fresh air outlet 20. Figure 3 Dehumidifiers such as Figure 4 As shown, the dehumidifier control method may further include:

[0057] Step S104: determining whether the space temperature exceeds a second set temperature range, where the second set temperature range is different from the first set temperature range.

[0058] Step S105: When the space temperature exceeds the second set temperature range, the opening of the electric proportional valve of the surface cooler is adjusted.

[0059] The cooler 70 is a device for cooling air. When used in a dehumidifier, the cooler 70 can cool the fresh air when it passes through, so that the water vapor in the fresh air condenses in the cooler 70, thereby reducing the humidity of the fresh air. In some embodiments of the present application, by adjusting the opening of the electric proportional valve of the cooler 70, not only the humidity of the fresh air can be adjusted, but also the temperature of the fresh air can be adjusted, thereby achieving the effect of adjusting the temperature of the target space.

[0060] The second set temperature range may also be a temperature range pre-set before the dehumidifier starts running, or a temperature range set during the operation of the dehumidifier. For example, a human-computer interaction system may be set in the dehumidifier, and the user may set or modify the second set temperature range during the operation of the dehumidifier through the human-computer interaction system.

[0061] When the space temperature exceeds the second set temperature range, adjusting the opening of the electric proportional valve of the surface cooler can also play a role in regulating the space temperature of the target space. Combined with the adjustment of the fan frequency within the first set temperature range, it can have a better regulating effect on the space temperature of the target space.

[0062] In some embodiments of the present application, the second set temperature range is greater than the third set temperature, the third set temperature is less than the first set temperature, and the difference between the third set temperature and the first set temperature is greater than or equal to 0.3°C and less than or equal to 0.7°C.

[0063] Specifically, the difference between the third set temperature and the first set temperature may be, for example, 0.4° C., 0.5° C., etc., and may be flexibly set according to actual needs.

[0064] The space temperature is between the first set temperature and the third set temperature. As the space temperature fluctuates, there is a high possibility that it will drop below the third set temperature, resulting in frequent adjustment of the opening of the electric proportional valve of the cooler and high energy consumption. By setting the third set temperature lower than the first set temperature, when the space temperature is maintained near the third set temperature for a long time, the possibility of the space temperature dropping below the third set temperature can be reduced by adjusting the fan frequency, thereby reducing the energy consumption of the dehumidifier. By setting the difference between the third set temperature and the first set temperature to be greater than or equal to 0.3°C, the problem of frequent changes in the space temperature above and below the first set temperature due to temperature fluctuations caused by the difference being too small can be reduced, and the problem of difficulty in triggering the adjustment of the fan frequency can be reduced. By setting the difference between the third set temperature and the first set temperature to be less than or equal to 0.7°C, the problem of frequent triggering of the adjustment of the fan frequency can be reduced due to the difference being too large, resulting in the space temperature being below the first set temperature for a long time.

[0065] In some embodiments of the present application, the second set temperature range is smaller than the fourth set temperature; the fourth set temperature is greater than the second set temperature, and the difference between the fourth set temperature and the second set temperature is greater than or equal to 0.3°C and less than or equal to 0.7°C.

[0066] Specifically, the difference between the fourth set temperature and the second set temperature may be, for example, 0.4° C., 0.5° C., etc., and may be flexibly set according to actual needs.

[0067] When the space temperature is near the fourth set temperature, as the space temperature fluctuates, there is a high possibility that it will rise above the fourth set temperature, resulting in frequent adjustment of the opening of the electric proportional valve of the cooler and high energy consumption. By setting the fourth set temperature greater than the second set temperature, when the space temperature is maintained near the fourth set temperature for a long time, the possibility of the space temperature rising above the fourth set temperature can be reduced by adjusting the fan frequency, thereby reducing the energy consumption of the dehumidifier. By setting the difference between the fourth set temperature and the second set temperature to be greater than or equal to 0.3°C, the problem of frequent fluctuations of the space temperature above the second set temperature due to the small difference and the difficulty in triggering the adjustment of the fan frequency can be reduced. By setting the difference between the fourth set temperature and the second set temperature to be less than or equal to 0.7°C, the problem of frequent triggering of the adjustment of the fan frequency due to the large difference and the space temperature being above the second set temperature for a long time can be reduced.

[0068] In addition, in some embodiments of the present application, the dehumidifier control method may further include: displaying the fan frequency of the processing fan in real time.

[0069] Specifically, for example, a display may be provided in the dehumidifier to display the fan frequency of the processing fan in real time on the display. Alternatively, the fan frequency of the processing fan may be sent to an external display device such as a mobile phone or computer of a staff member, and the fan frequency of the processing fan may be displayed in real time on the external display device.

[0070] The fan frequency of the processing fan is displayed in real time, which can help the staff to judge whether the processing fan is faulty when the indoor temperature is abnormal.

[0071] Please refer to Figure 5 , the present application provides a dehumidifier in another embodiment, which is used to adjust the air humidity and air temperature in the target space 200. The dehumidifier includes: a fresh air inlet 10 and a fresh air outlet 20, a regeneration air inlet 50 and a regeneration air outlet 60, and a rotor 30 and a processing fan 40 arranged between the fresh air inlet 10 and the fresh air outlet 20, a desiccant is arranged in the rotor 30, the rotor 30 includes a drying area 31 and a regeneration area 32, the drying area 31 is arranged between the fresh air inlet 10 and the fresh air outlet 20, and the air outlet direction of the processing fan 40 is toward the drying area 21; a temperature sensor 80, the temperature sensor 80 is arranged in the target space 200, and is used to measure and obtain the space temperature of the target space 200; a control device 90, the control device 90 is used to obtain the space temperature, determine whether the space temperature exceeds the first set temperature range for a set time, and when the space temperature exceeds the first set temperature range for a set time, adjust the fan frequency of the processing fan 40.

[0072] Among them, the number of temperature sensors 50 can be one or more. When the number of temperature sensors 80 is more than one, multiple temperature sensors 80 can be set at multiple different positions in the target space 200, and each temperature sensor 80 respectively measures the air temperature of each corresponding position. Finally, the control device uses the average value, minimum value, maximum value, or median of the multiple air temperatures measured by all the temperature sensors 80 as the space temperature of the target space 200.

[0073] The control device 90 may be a control chip in the dehumidifier or an integral structure including the control chip. The control device 90 may be connected to the temperature sensor 80 and the processing fan 40 in communication, for example, by a bus, radio, etc., and provide an established communication channel to obtain the space temperature from the temperature sensor 80 and control and adjust the fan frequency of the processing fan 40.

[0074] Compared with the related art, in the dehumidifier provided in the embodiment of the present application, the control device 90 controls and adjusts the fan frequency of the processing fan 40 when it is determined that the space temperature exceeds the first set temperature range for a set time. The change in the fan frequency can change the wind speed of the dehumidifier in delivering fresh air to the target space, thereby regulating the temperature in the target space 200. By setting the set time, the frequent changes in the fan frequency of the processing fan 40 due to temperature fluctuations can be reduced. Since the sudden change process of the fan frequency may generate a large induced current, resulting in increased energy consumption, reducing the frequent changes in the fan frequency of the processing fan 40 due to temperature fluctuations can effectively reduce the energy consumption in the temperature adjustment process.

[0075] In addition, in some embodiments of the present application, Figure 5 As shown, the dehumidifier may further include: a surface cooler 70. The surface cooler 70 is arranged between the fresh air inlet 10 and the fresh air outlet 20; the control device 90 is also used to determine whether the space temperature exceeds the second set temperature range, the second set temperature range is different from the first set temperature range, and when the space temperature exceeds the second set temperature range, the electric proportional valve opening of the surface cooler 70 is adjusted.

[0076] The control device 90 may be connected to the cooler 70 for communication, for example, via a bus, radio, etc., and provide an established communication channel to control and adjust the opening of the electric proportional valve of the cooler 70 .

[0077] When the control device 60 determines that the space temperature exceeds the second set temperature range, it controls and adjusts the opening of the electric proportional valve of the surface cooler 70, which can also play a role in regulating the space temperature. Combined with the adjustment of the fan frequency within the first set temperature range, it can have a better adjustment effect on the space temperature of the target space.

[0078] In addition, in some embodiments of the present application, Figure 5 As shown, the dehumidifier may further include: a return air inlet 80 and a return air outlet 90 ; the return air inlet 80 is connected to the target space 200 , and the return air outlet 90 is disposed between the processing fan 40 and the fresh air inlet 10 .

[0079] The return air inlet 80 is connected to the target space 200, and the return air outlet 90 is arranged between the processing fan 40 and the fresh air inlet 10. When the processing fan 40 is in operation, air can be drawn from the target space 200 through the return air inlet 80, and return air is formed between the return air inlet 80 and the return air outlet 90. The dehumidifier delivers fresh air to the target space 200 through the fresh air outlet 20, and draws air from the target space 200 through the return air inlet 80 to form return air, thereby forming a circulating airflow in the target space 200.

[0080] Adjusting the fan frequency of the processing fan 40 can adjust the return air volume drawn from the target space by the processing fan 40, thereby achieving a better adjustment effect on the space temperature of the target space 200.

[0081] Please refer to Figure 6 The embodiment of the present application also provides a dehumidifier control device, including: a communication module 601, the communication module 601 is used to obtain the space temperature of the target space; a judgment module 602, the judgment module 602 is used to judge whether the space temperature remains within the first set temperature range for a set time; a control module 603, the control module 603 is used to adjust the fan frequency of the processing fan when the space temperature remains within the first set temperature range for a set time.

[0082] Compared with the related art, in the dehumidifier control device provided in the embodiment of the present application, when the judgment module 602 determines that the space temperature exceeds the first set temperature range for a set time, the control module 603 controls and adjusts the fan frequency of the processing fan. The change in fan frequency can change the wind speed of the dehumidifier in delivering fresh air to the target space, thereby regulating the temperature in the target space. By setting the set time, the fan frequency of the processing fan can be reduced due to frequent changes in temperature fluctuations. Since the sudden change process of the fan frequency may generate a large induced current, resulting in increased energy consumption, reducing the frequent changes in the fan frequency of the processing fan due to temperature fluctuations can effectively reduce the energy consumption in the temperature regulation process.

[0083] In addition, in other embodiments of the present application, the judgment module 602 can also be used to determine whether the space temperature exceeds a second set temperature range, which is different from the first set temperature range; the control module 603 is also used to adjust the opening of the electric proportional valve of the surface cooler when the space temperature exceeds the second set temperature range.

[0084] In addition, in some other embodiments of the present application, the communication module 601 is also used to send the fan frequency of the processed fan to a display device for real-time display.
