[0002] A damp environment can easily cause indoor clothing, food, and other items to become damp and moldy, and may even lead to water stains on floors and walls, affecting people's daily lives. The ideal humidity for the human body is 60%-70%, and dehumidifiers can effectively regulate indoor humidity to meet people's various humidity needs.

[0003] Most dehumidifiers currently available are equipped with humidity sensors to detect the actual indoor humidity, allowing the dehumidifier to operate and reduce the indoor humidity to the target or preset suitable humidity level. However, humidity sensors are relatively expensive, increasing the overall cost of the dehumidifier. Summary of the Invention

Attached Figure Description

[0034] To more clearly illustrate the technical solutions in this invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of this invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0036] Figure 2 This is the second flowchart of the dehumidifier control method provided by the present invention;

[0037] Figure 3 This is a schematic diagram of the dehumidifier control device provided by the present invention;

[0038] Figure 4 This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0040] The following is combined with Figures 1-2 The dehumidifier control method of the present invention is described.

[0041] Figure 1 This is one of the flowcharts for a dehumidifier control method provided in an embodiment of the present invention. For example... Figure 1 As shown, the dehumidifier control method includes:

[0042] Step 110: Obtain the ambient temperature and coil temperature;

[0043] Step 120: Determine the relative humidity of the environment based on the ambient temperature and the coil temperature;

[0044] Step 130: Control the operation of the dehumidifier based on the relative humidity and the ambient temperature.

[0045] This dehumidifier features a temperature sensor but no humidity sensor, thus reducing its cost. Alternatively, it can communicate with devices like air conditioners, using the air conditioner's temperature sensor to obtain the ambient temperature. The coil temperature is detected by a temperature sensing element located on the coil. Compared to traditional dehumidifiers with humidity sensors, this invention eliminates the need for a humidity sensor, requiring only a lower-cost temperature sensor, further reducing overall cost.

[0046] The coil temperature is the dew point temperature. In one specific embodiment, the actual water vapor pressure of the environment is determined based on the ambient temperature, the saturated water vapor pressure of the environment is determined based on the coil temperature, i.e., the dew point temperature, and the relative humidity of the environment is determined based on the actual water vapor pressure and the saturated water vapor pressure, so that the current ambient temperature can be converted into ambient humidity according to the relative humidity, which makes it convenient for the dehumidifier to control the operation of the dehumidifier according to the ambient humidity.

[0047] It should be noted that the dehumidifier has a one-button dehumidification mode. When the one-button dehumidification mode is activated, the dehumidifier's fan and compressor will run continuously without stopping, and the operation of the dehumidifier will no longer be controlled according to the current ambient temperature and relative humidity.

[0048] The dehumidifier control method provided in this invention obtains the ambient temperature and coil temperature, determines the relative humidity based on the ambient temperature and coil temperature, and controls the dehumidifier based on the ambient temperature and relative humidity. The entire control method does not involve humidity detection; it only needs to control the operation of the dehumidifier based on the ambient temperature and coil temperature, thereby helping to simplify the detection components and reduce detection costs.

[0049] Based on the above embodiments, such as Figure 2 As shown, determining the relative humidity of the environment based on ambient temperature and coil temperature specifically includes:

[0050] Step 210: Determine the actual water vapor pressure of the environment based on the ambient temperature, and determine the saturated water vapor pressure of the environment based on the coil temperature;

[0051] Step 220: Determine the relative humidity of the environment based on the actual water vapor pressure and the saturated water vapor pressure. Let the ambient temperature be T. room The coil temperature is T. pipe The actual water vapor pressure e is:

[0052] e = e s0 exp[a*T room / (T room +273.15-b)]

[0053] In the formula, e s0 e is the saturated water vapor pressure at 0 degrees Celsius. s0 =6.1078; a and b are two fixed coefficients under saturated water vapor pressure at 0 degrees, a = 17.296, b = 35.86.

[0054] The saturated water vapor pressure E is determined based on the coil temperature as follows:

[0055] E = e s0 exp[a*T pipe / (T pipe +273.15-b)]

[0056] The relative humidity (RH) of the environment is determined based on the actual water vapor pressure and the saturated water vapor pressure.

[0057] RH = e / E * 100%

[0058] The dehumidifier control method provided in this embodiment of the invention determines the actual water vapor pressure of the environment by using the ambient temperature, determines the saturated water vapor pressure of the environment based on the coil temperature, and then determines the relative humidity by combining the actual water vapor pressure and the saturated water vapor pressure of the environment.

[0059] In another specific embodiment of the present invention, the relative humidity of the environment is determined by consulting the enthalpy-humidity chart based on the ambient temperature and the coil temperature.

[0060] Based on the above embodiments, in order to improve the reliability and accuracy of relative humidity, the ambient temperature and coil temperature obtained at the same time are used as a set of measurement values. A relative humidity value is determined based on each set of measurement values. Multiple relative humidity values ​​can be determined based on multiple sets of measurement values. The average value of multiple relative humidity values ​​is used as the relative humidity value.

[0061] Among them, the ambient temperature and coil temperature can be obtained at preset time intervals within a sampling cycle, or they can be obtained at least three sets of ambient temperature and judgment temperature when the dehumidifier is started.

[0062] In one optional embodiment, the average of multiple relative humidity values ​​is directly used as the relative humidity. In yet another optional embodiment, the relative humidity values ​​corresponding to the first and last sets of measurements within the sampling period are discarded before calculating the average.

[0063] The dehumidifier control method provided in this embodiment of the invention obtains multiple sets of ambient temperature and coil temperature to determine multiple relative humidity values, and uses the average of multiple relative humidity values ​​as the relative humidity, thereby improving the reliability and accuracy of relative humidity.

[0064] In a specific embodiment of the present invention, controlling the operation of the dehumidifier based on ambient temperature and relative humidity specifically includes:

[0065] The first and second target temperatures are determined based on relative humidity.

[0066] When the ambient temperature is not lower than the first target temperature, control the dehumidifier's compressor to start and control the dehumidifier's fan to rotate;

[0067] When the ambient temperature is not higher than the second target temperature, the dehumidifier's compressor is turned off, and the dehumidifier's fan is turned off after running for a preset time.

[0068] The first target temperature is the temperature value corresponding to a relative humidity increase of 5, and the second target temperature is the temperature value corresponding to a relative humidity decrease of 5.

[0069] Specifically, the first target temperature value and the second target temperature value are determined based on the relative humidity (RH).

[0070] The first target temperature value T1 satisfies the following formula:

[0071] e s0 exp[a*T1 / (T1+273.15-b)]=(RH+5)*e s0 exp[a*T pipe / (T pipe +273.15-b)]

[0072] The second target temperature value T2 satisfies the following formula:

[0073] e s0 exp[a*T2 / (T2+273.15-b)]=(RH-5)*e s0 exp[a*T pipe / (T pipe +273.15-b)]

[0074] The first target temperature value T1 and the second target temperature value T2 are determined based on the above formula, and the operation of the dehumidifier is controlled based on the relative magnitude of the ambient temperature and the first and second target temperature values.

[0075] Optionally, the preset duration is 2-5 minutes. For example, the preset duration is 3 minutes or 4 minutes.

[0076] The dehumidifier control method provided in this embodiment of the invention controls the automatic start and stop of the dehumidifier based on the ambient temperature and relative humidity, so that the ambient humidity is maintained at the humidity set by the user.

[0077] In one specific embodiment of the present invention, the dehumidifier operates at the wind speed set by the user.

[0078] In another specific embodiment of the present invention, the fan speed is controlled based on ambient temperature and relative temperature.

[0079] Specifically, the third and fourth target temperatures are determined based on relative humidity;

[0080] When the ambient temperature is lower than the third target temperature, control the dehumidifier fan to run at the first speed.

[0081] When the ambient temperature is not lower than the third target temperature and is lower than the fourth target temperature, control the dehumidifier fan to run at the second speed.

[0082] When the ambient temperature is not lower than the fourth target temperature, control the dehumidifier fan to run at the third speed.

[0083] The third target temperature is the temperature value corresponding to a 10% increase in relative humidity, and the fourth target temperature is the temperature value corresponding to a 20% increase in relative humidity; the wind speed at the first setting is lower than the wind speed at the second setting, and the wind speed at the second setting is lower than the wind speed at the third setting.

[0084] The third target temperature value T3 satisfies the following formula:

[0085] e s0 exp[a*T3 / (T3+273.15-b)]=(RH+10)*e s0 exp[a*T pipe / (T pipe+273.15-b)]

[0086] The fourth target temperature value T4 satisfies the following formula:

[0087] e s0 exp[a*T4 / (T4+273.15-b)]=(RH+20)*e s0 exp[a*T pipe / (T pipe +273.15-b)]

[0088] Based on the above formulas, the third and fourth target temperature values ​​are determined respectively. During the operation of the dehumidifier, the fan speed is controlled according to the relative relationship between the ambient temperature and the third and fourth target temperatures.

[0089] When the ambient temperature is below the third target temperature, the ambient humidity is close to the user-set humidity, and the dehumidifier's fan operates at low speed. When the ambient temperature is not lower than the fourth target temperature, the ambient humidity differs significantly from the user-set humidity, and the dehumidifier's fan operates at high speed. When the ambient humidity is between the third and fourth target temperatures, the dehumidifier's fan operates at medium speed. Therefore, by controlling the fan's operating state in stages according to the ambient temperature during operation, dehumidification efficiency is improved and energy consumption is reduced.
