[0055] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is given in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0056] This embodiment provides a dehumidification control method, a control device and a dehumidifier. Figures 1-6 As shown. Among them, Figure 6 A schematic diagram of the connection between the front panel 110, fan, sub-board 300, and drive assembly in the dehumidifier provided in an embodiment of the present invention, with the sub-board 300 in a blocked position; Figure 6 The dehumidifier shown is capable of executing the above-mentioned dehumidification control method. Specifically, the dehumidifier includes a shell 100, in which a dehumidification air duct extending in the front-to-back direction and a fan connected to the front air duct opening of the dehumidification air duct are provided. The evaporator and condenser are arranged in sequence from back to front in the dehumidification air duct, and the back panel of the shell 100 is provided with a main air inlet corresponding to the rear air duct opening of the dehumidification air duct; the shell 100 is provided with an auxiliary air inlet 111 connected to the rear air duct opening, and a sub-board 300 is provided at the auxiliary air inlet 111. The shell 100 or the fan is connected to a drive assembly, and the drive end of the drive assembly is connected to the sub-board 300, which is used to drive the sub-board 300 to move to change the air inlet area of ​​the auxiliary air inlet 111.

[0057] When the dehumidifier is in use, it is turned on and operated. Specifically, the main air inlet and the dehumidification component are both opened. The ambient air enters the housing 100 through the main air inlet under the suction action of the fan, and then flows through the evaporator in sequence for condensation and dehumidification. After the condenser temperature rises, it flows into the fan through the air intake port, and then flows back to the environment through the exhaust port of the fan, completing the main dehumidification adjustment of the ambient air. During the main dehumidification adjustment process, the dehumidification control method provided in this embodiment can also be used to perform auxiliary dehumidification adjustment. Figure 1 Schematic diagram of the flow of the first dehumidification control method provided according to an embodiment of the present invention. Figure 1 As shown, the dehumidification control method includes:

[0058] The dehumidifier is turned on and running.

[0059] S102 obtains the suitable humidity range of the current season and the current ambient humidity.

[0060] The dehumidifier can obtain the current season through the Internet or manually set by the user, and then retrieve the appropriate humidity range corresponding to the current season from the database. The current ambient humidity is detected by a humidity sensor provided in the housing 100. Specifically, the humidity sensor can be located at the main air inlet. Specifically, May to October of each year can be set as summer, and the remaining months as winter. The appropriate humidity range in summer is 40% to 60%, and the appropriate humidity range in winter is 50% to 80%.

[0061] S104 adjusts the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan according to the appropriate humidity range and the current ambient humidity.

[0062] When the dehumidifier is in use, the air inlet area of ​​the auxiliary air inlet 111 determines the effective air circulation area of ​​the dehumidifier. On the basis of a certain suction intensity of the fan, the air flow rate flowing through the dehumidification component can be adjusted by adjusting the air inlet area of ​​the auxiliary air inlet 111, and the adjustment does not affect the intensity of the main dehumidification adjustment, thereby relatively independently adjusting the dehumidification capacity and effect of the dehumidification component on the ambient air; at the same time, the operating power of the fan determines the suction intensity of the fan on the airflow. By adjusting the operating power of the fan, the airflow speed of both the main air inlet and the auxiliary air inlet 111 can be adjusted, thereby significantly changing the air flow rate flowing through the dehumidification component, and correspondingly adjusting the dehumidification capacity and effect of the dehumidification component on the ambient air to a higher degree. During the operation of the dehumidifier, the current ambient humidity is compared with the appropriate humidity range. If the current ambient humidity is within the appropriate humidity range, it indicates that the dehumidifier can well complete the adjustment of the ambient humidity through the main dehumidification adjustment of the main air inlet and the current closure or auxiliary dehumidification adjustment of the auxiliary air inlet 111. The air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan can be controlled accordingly to maintain the current state; if the current ambient humidity is outside the appropriate humidity range and is greater than its upper limit threshold, it indicates that the current ambient humidity is too high and the current dehumidification adjustment ability of the dehumidifier is too weak. At this time, the auxiliary air inlet 111 can be adjusted to increase the air inlet area and the operating power of the fan. At least one of the air inlet area and the operating power of the fan can be adjusted to improve the dehumidification ability of the dehumidifier and the dehumidifier on the ambient air, so that the current ambient humidity can be reduced to within the appropriate humidity range; if the current ambient humidity is outside the appropriate humidity range and is less than its lower limit threshold, it indicates that the current ambient humidity is low and the current dehumidification adjustment ability of the dehumidifier is high. At this time, at least one of the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan can be adjusted to reduce, thereby weakening the dehumidification ability and effect of the dehumidifier and the dehumidifier on the ambient air, so that the current ambient humidity can be restored to near the appropriate humidity range.

[0063] The dehumidification control method provided in this embodiment can perform secondary auxiliary humidity adjustment on the main dehumidification adjustment by adjusting the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan on the basis of the main dehumidification adjustment, thereby improving the humidity adjustment range, capacity, accuracy and intelligence of the dehumidifier, so that the ambient humidity can quickly and accurately reach the appropriate humidity range with higher user comfort in the current season, which greatly improves the user's comfort and convenience of use.

[0064] Optionally, the step S104 of adjusting the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan according to the suitable humidity range and the current ambient humidity includes: judging whether the current ambient humidity is within the suitable humidity range; if so, controlling the auxiliary air inlet 111 and the fan to maintain the current state; if not, controlling the dehumidifier to enter the first auxiliary adjustment mode, in which the current humidity deviation value of the current ambient humidity from the suitable humidity range is obtained, and adjusting the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan according to the current ambient humidity and the current humidity deviation value, so that the current ambient humidity is within the suitable humidity range.

[0065] After obtaining the current season, the suitable humidity range and the current ambient humidity according to step S102, first determine whether the current ambient humidity is within the suitable humidity range. If it is within the suitable humidity range, it indicates that the dehumidifier can well complete the adjustment of the ambient humidity through the main dehumidification adjustment of the main air inlet and the current closure or auxiliary dehumidification adjustment of the auxiliary air inlet 111. Control the auxiliary air inlet 111 and the fan to maintain the current state. If the current ambient humidity is outside the suitable humidity range, it indicates that the ability of the dehumidifier to adjust the main dehumidification through the main air inlet is too high or too low. Accordingly, the dehumidifier is controlled to enter the first auxiliary adjustment mode to assist the main dehumidification adjustment for secondary adjustment. Specifically, if the current ambient humidity is greater than the upper limit threshold of the suitable humidity range, it indicates that the current ambient humidity is too high and the main dehumidification adjustment ability of the dehumidifier through the main air inlet is too weak. The difference between the current ambient humidity and the upper limit threshold is calculated as the current humidity deviation value. The current humidity deviation value can indicate the high degree of the current ambient humidity. If the current ambient humidity is less than the lower limit threshold of the suitable humidity range, it indicates that the current ambient humidity is too high. The humidity is low, and the main dehumidification adjustment capacity of the dehumidifier through the main air inlet is high. The difference between the lower limit threshold and the current ambient humidity is calculated as the current humidity deviation value, and the current humidity deviation value can represent the low degree of the current ambient humidity; then, according to the high or low state of the ambient humidity represented by the current ambient humidity and the high or low degree represented by the current humidity deviation value, the air inlet area of ​​the auxiliary air inlet 111 and the fan operating power are adjusted to a corresponding extent. By quickly and accurately adjusting the air flow through the dehumidifier, the current ambient humidity can quickly approach and be within the appropriate humidity range, thereby improving the user's comfort.

[0066] Specifically, in this embodiment, a matching sub-panel 300 can be hinged at the auxiliary air inlet 111 of the dehumidifier, and the air inlet area of ​​the auxiliary air inlet 111 can be adjusted by adjusting the angle between the sub-panel 300 and the auxiliary air inlet 111; the above-mentioned steps of adjusting the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan according to the current ambient humidity and the current humidity deviation value include: when the current ambient humidity is greater than the upper limit threshold of the suitable humidity range; if the current humidity deviation value is greater than or equal to zero and less than the first preset humidity, the control sub-panel 300 opens the first angle; if the current humidity deviation value is greater than or equal to the first preset humidity and less than the second preset humidity, the control sub-panel 300 opens the second angle; if the current humidity deviation value is greater than or equal to the second preset humidity, the control sub-panel 300 opens the third angle; wherein, the first preset humidity is greater than zero and less than the second preset humidity, and the first angle, the second angle and the third angle increase in sequence.

[0067] In the case where the current ambient humidity is relatively high, after entering the first auxiliary adjustment mode, the air inlet area of ​​the auxiliary air inlet 111, which is relatively independent of the humidity adjustment, is first adjusted. On the basis of being able to assist in adjusting the humidity to a certain extent, the impact on the main dehumidification adjustment and the loss of electric energy and its operating life caused by the increase in the fan operating power are reduced. Specifically, when the current humidity deviation value is greater than or equal to zero and less than the first preset humidity, it indicates that the current ambient humidity is less high than the upper limit threshold, so the opening angle of the control sub-board 300 is the smaller first angle, the auxiliary air inlet 111 has a smaller air inlet area, and the increase in the air flow through the dehumidifier is also smaller. Accordingly, the dehumidification capacity of the dehumidifier to the environment is improved to a smaller extent, so that the current ambient humidity can be quickly and stably reduced to an appropriate humidity range; when the current humidity deviation value is greater than or equal to the first preset humidity and less than the second preset humidity, it indicates that the current ambient humidity is more high than the upper limit threshold, so the opening angle of the control sub-board 300 is the larger second angle, the auxiliary air inlet 111 has a larger air inlet area, The increase in the amount of airflow flowing through the dehumidifier is also large, and accordingly, the dehumidification capacity of the dehumidifier to the environment is greatly improved, so that the current ambient humidity can be quickly and stably reduced to an appropriate humidity range; when the current humidity deviation value is greater than the second preset humidity, it indicates that the current ambient humidity is too high compared to the upper limit threshold, and the user's experience under the current ambient humidity is poor, so the opening angle of the control sub-board 300 is the third angle. At this time, the area of ​​the auxiliary air inlet 111 is equal to the air inlet area, that is, the opening degree of the auxiliary air inlet 111 is the maximum, and the corresponding increase in the amount of airflow flowing through the dehumidifier is also the largest, which maximizes the dehumidification capacity of the dehumidifier to the environment, so that the current ambient humidity can be reduced as quickly as possible to within the appropriate humidity range, and the user's experience can be quickly alleviated.

[0068] Specifically, the first preset humidity can be 3% to 7%, preferably 5%, and the second preset humidity can be 14% to 18%, preferably 16%. The first angle, the second angle, and the third angle are all angles between the sub-panel 300 and the auxiliary air inlet 111. The first angle can range from (0° to 40°), preferably 20°; the second angle can range from (40° to 90°), preferably 70°; and the third angle can be 90°.

[0069] For the situation where the current ambient humidity is relatively low, in this embodiment, the steps of adjusting the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan according to the current ambient humidity and the current humidity deviation value include: when the current ambient humidity is lower than the lower limit threshold of the suitable humidity range, if the current humidity deviation value is greater than or equal to zero and less than the third preset humidity, the control sub-board 300 is turned off; if the current humidity deviation value is greater than or equal to the third preset humidity and less than the fourth preset humidity, the control sub-board 300 is turned off and the fan speed is reduced to the first preset speed; if the current humidity deviation value is greater than or equal to the fourth preset humidity, the control sub-board 300 is turned off and the fan speed is reduced to the second preset speed; wherein, the third preset humidity is greater than zero and less than the fourth preset humidity, and the first preset speed is less than the second preset speed.

[0070] In the case where the current ambient humidity is low, after entering the first auxiliary adjustment mode, when the current humidity deviation value is greater than or equal to zero and less than the third preset humidity, it indicates that the current ambient humidity is less lower than the lower limit threshold and the current dehumidification intensity of the dehumidifier is less high. Therefore, the fan is controlled to maintain the current operating state and the sub-board 300 is controlled to be closed. Only by closing the auxiliary air inlet 111, the air flow passing through the dehumidifier is reduced to reduce the dehumidification intensity of the dehumidifier to a small extent, so that the current ambient humidity can quickly and stably return to the appropriate humidity range; when the current humidity deviation value is greater than or equal to the third preset humidity and less than the fourth preset humidity, it indicates that the current ambient humidity is much lower than the lower limit threshold and the current dehumidification intensity of the dehumidifier is much higher. At this time, not only the sub-board 300 is controlled to be closed, but also the speed of the fan is controlled to be reduced to the first preset value with a smaller speed. The speed is set, so that the dehumidification intensity of the dehumidifier is reduced to a large extent by closing the auxiliary air inlet 111 and reducing the suction intensity of the fan, so that the current ambient humidity can quickly return to the appropriate humidity range; when the current humidity deviation value is greater than the fourth preset humidity, it indicates that the current ambient humidity is too low compared to the lower limit threshold, the ineffective dehumidification intensity of the dehumidifier on the environment is too high, and the user comfort is poor. At this time, not only the auxiliary air inlet 111 is controlled to be closed to reduce the air flow entering the dehumidifier, but the speed of the fan is also controlled to reduce the larger second preset speed to further reduce the air flow at the main air inlet, thereby greatly reducing the dehumidification intensity of the dehumidifier on the environment, so that the current ambient humidity can quickly approach the appropriate humidity environment, quickly alleviate the user's usage experience, and reduce the consumption of electricity and service life caused by the ineffective operation of the dehumidifier.

[0071] Specifically, the third preset humidity can be 3% to 7%, preferably 5%, the fourth preset humidity can be 14% to 18%, preferably 16%. The first preset speed can be 25 rpm to 35 rpm, preferably 30 rpm, and the second preset speed can be 45 rpm to 55 rpm, preferably 50 rpm.

[0072] In this embodiment, after the first auxiliary adjustment mode runs for a first preset time, the dehumidifier is controlled to enter a second auxiliary adjustment mode. In the second auxiliary adjustment mode, the adjusted ambient humidity and the adjusted humidity deviation value of the adjusted ambient humidity from the appropriate humidity range are obtained. The air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan are adjusted according to the adjusted ambient humidity and the adjusted humidity deviation value to keep the adjusted ambient humidity within the appropriate humidity range. After the first auxiliary adjustment mode auxiliary adjustment of the dehumidifier's dehumidification effect for a first preset time, the first auxiliary adjustment mode exits and the dehumidifier is controlled to enter the second auxiliary adjustment mode. By re-testing and adjusting the adjustment effect of the first auxiliary adjustment mode, the adjustment accuracy of the dehumidifier's dehumidification effect is further improved. Specifically, the ambient humidity adjusted by the first auxiliary adjustment mode is obtained as the adjusted ambient humidity. First, it is determined whether the adjusted ambient humidity is within the appropriate humidity range. If it is within the appropriate humidity range, it indicates that the dehumidifier has been able to effectively adjust the ambient humidity after adjustment by the first auxiliary adjustment mode. The auxiliary air inlet 111 and the fan are controlled to maintain their current state. If the regulated ambient humidity is outside the suitable humidity range, it indicates that the dehumidification regulation intensity of the dehumidifier after adjustment by the first auxiliary adjustment mode is still too high or too low, and the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan are adjusted again accordingly. Specifically, if the regulated ambient humidity is greater than the upper limit threshold, it indicates that the regulated ambient humidity is too high and the current dehumidification regulation intensity of the dehumidifier is too weak. The difference between the regulated ambient humidity and the upper limit threshold is calculated as the regulated humidity deviation value, and the regulated humidity deviation value can indicate the high degree of the regulated ambient humidity; if the regulated ambient humidity is less than the lower limit threshold, it indicates that the regulated ambient humidity is too low and the dehumidification regulation intensity of the dehumidifier is too weak. If the section intensity is too high, the difference between the lower limit threshold and the adjusted ambient humidity is calculated as the adjusted humidity deviation value, and the adjusted humidity deviation value can represent the low degree of the current ambient humidity; then, according to the high or low state of the ambient humidity represented by the adjusted ambient humidity and the high or low degree represented by the adjusted humidity deviation value, the air inlet area of ​​the auxiliary air inlet 111 and the fan operating power are readjusted to a corresponding extent, and the air flow through the dehumidifier is adjusted quickly and accurately, so that the adjusted ambient humidity can quickly approach and be within the appropriate humidity range, thereby further improving the adjustment accuracy of the dehumidifier and improving the user's comfort.

[0073] Specifically, the first preset duration can be selected from 15 minutes to 25 minutes, preferably 20 minutes.

[0074] In this embodiment, for the case where the current ambient humidity in the first auxiliary adjustment mode is greater than the upper limit threshold of the suitable humidity range, in the second auxiliary adjustment mode, the steps of adjusting the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan according to the adjusted ambient humidity and the adjusted humidity deviation value include: when the adjusted ambient humidity is greater than the upper limit threshold; if the adjusted humidity deviation value is greater than or equal to zero and less than the fifth preset humidity, the control sub-board 300 and the fan maintain the current state; if the adjusted humidity deviation value is greater than or equal to the fifth preset humidity and less than the sixth preset humidity, the opening angle of the control sub-board 300 is increased by the first preset angle and the speed of the fan is increased by the third preset speed; if the adjusted humidity deviation value is greater than or equal to the sixth preset humidity, the opening angle of the control sub-board 300 is increased to the maximum angle, and the speed of the fan is increased by the fourth preset speed; wherein, the fifth preset humidity is less than the sixth preset humidity, and the third preset speed is less than the fourth preset speed.

[0075] The goal of the first auxiliary adjustment mode is to reduce the ambient humidity. In the second auxiliary adjustment mode, the adjusted ambient humidity is obtained and compared with the appropriate humidity range. When the adjusted ambient humidity is within the appropriate humidity range, it indicates that after adjustment by the first auxiliary adjustment mode, the current dehumidification intensity of the dehumidifier can better dehumidify the ambient humidity. Then, the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan can be controlled to maintain the current state. When the adjusted ambient humidity is greater than the upper limit threshold, it indicates that the current dehumidification intensity of the dehumidifier is still weak after adjustment by the first auxiliary adjustment mode. Therefore, the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan are adaptively adjusted again. Specifically, when the adjusted humidity deviation value is greater than or equal to zero and less than the fifth preset humidity, it indicates that the dehumidifier has been able to effectively control the ambient humidity to gradually approach the upper limit threshold or has stably controlled the ambient humidity within a range close to the upper limit threshold after adjustment by the first auxiliary adjustment mode. Therefore, the air inlet area of ​​the auxiliary air inlet 111 and the fan can be controlled to maintain the current operating state; when the adjusted humidity deviation value is greater than or equal to the fifth preset humidity and less than the sixth preset humidity, it indicates that the dehumidification intensity of the dehumidifier is still weak after adjustment by the first auxiliary adjustment mode. At this time, the control sub-board 300 increases the first preset angle on the basis of the current angle and controls the fan at the current angle. The third preset speed is increased on the basis of the previous speed, thereby increasing the air flow through the dehumidifier by increasing the air inlet area of ​​the auxiliary air inlet 111 and the suction strength of the fan, corresponding to enhancing the dehumidification strength of the dehumidifier in two aspects, so that the regulated ambient humidity can be reduced to near the upper limit threshold and enter the appropriate humidity range; when the regulated humidity deviation value is greater than the sixth preset humidity, it indicates that the dehumidification strength of the dehumidifier after adjustment by the first auxiliary adjustment mode is still too weak, then the opening angle of the control sub-board 300 is the maximum angle, that is, the air inlet area of ​​the auxiliary air inlet 111 is the maximum area, and at the same time, the fan is controlled to increase the larger fourth preset speed on the basis of the current speed to greatly increase the suction strength of the fan, thereby greatly increasing the air flow through the dehumidifier in two aspects, so as to greatly increase the dehumidification strength of the dehumidifier, so that it can effectively reduce the ambient humidity and quickly improve the user comfort.

[0076] Specifically, the fifth preset humidity can be 3% to 7%, preferably 5%, the sixth preset humidity can be 14% to 18%, preferably 16%. The first preset angle can be 8° to 12°, preferably 10°; the maximum angle can be 90°; the third preset speed can be 25 rpm to 35 rpm, preferably 30 rpm; and the fourth preset speed can be 45 rpm to 55 rpm, preferably 50 rpm.

[0077] If the current ambient humidity in the first auxiliary adjustment mode is less than the lower threshold of the suitable humidity range, in the second auxiliary adjustment mode, the steps of adjusting the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan according to the adjusted ambient humidity and the adjusted humidity deviation value include: if the adjusted ambient humidity is less than the lower threshold, shutting down the control sub-board 300 and reducing the fan speed by a fifth preset speed. The goal of the first auxiliary adjustment mode is to increase the ambient humidity. In the second auxiliary adjustment mode, the adjusted ambient humidity is obtained and compared with the suitable humidity range. When the adjusted ambient humidity is within the suitable humidity range, it indicates that the current dehumidification intensity of the dehumidifier is able to effectively dehumidify the ambient humidity after adjustment in the first auxiliary adjustment mode. In this case, the air inlet area of ​​the auxiliary air inlet 111 and the operating power of the fan are controlled to maintain their current states. When the adjusted ambient humidity is less than the lower limit threshold, it indicates that after adjustment by the first auxiliary adjustment mode, the current dehumidification intensity of the dehumidifier is still too high. Therefore, the sub-board 300 is controlled to be turned off and the fan is controlled to reduce the fifth preset speed again on the basis of the current speed to further reduce the dehumidification intensity of the dehumidifier, and accordingly further reduce the effect of the dehumidifier on reducing the ambient humidity, so that the ambient humidity can recover and approach the lower limit threshold and quickly reach the appropriate humidity range.

[0078] The second auxiliary adjustment mode ends after the second preset time, and one cycle adjustment is completed. The dehumidifier can perform step S102 again to enter the next cycle adjustment, thereby achieving continuous cycle adjustment of the ambient humidity. Specifically, the second preset time can be 25 minutes to 35 minutes, preferably 30 minutes.

[0079] Specifically, in this embodiment, for the step of "obtaining the current humidity deviation value of the current ambient humidity from the suitable humidity range" in the first auxiliary adjustment mode, it includes: calculating the absolute value of the difference between the current ambient humidity and the lower limit threshold of the suitable humidity range as the current lower limit deviation value, and the absolute value of the difference with the upper limit threshold of the suitable humidity range as the current upper limit deviation value, and taking the smaller of the current lower limit deviation value and the current upper limit deviation value as the current humidity deviation value. The suitable humidity range is [Hmin, Hmax]. If the current ambient humidity is H1, then calculate |H1-Hmin| as the current lower limit deviation value and |H1-Hmax| as the current upper limit deviation value. When H1 is greater than the upper limit threshold, |H1-Hmax|<|H1-Hmin|, and |H1-Hmax| is taken as the current humidity deviation value. When H1 is less than the lower limit threshold, |H1-Hmin|<|H1-Hmax|, and |H1-Hmin| is taken as the current humidity deviation value.

[0080] Similarly, for the step of "obtaining the adjusted regulated environmental humidity and the regulated humidity deviation value of the regulated environmental humidity from the suitable humidity range" in the second auxiliary adjustment mode, it includes: obtaining the adjusted regulated environmental humidity, calculating the absolute value of the difference between the regulated environmental humidity and the lower limit threshold of the suitable humidity range as the adjustment lower limit deviation value, and the absolute value of the difference between the regulated environmental humidity and the upper limit threshold of the suitable humidity range as the adjustment upper limit deviation value, and taking the smaller of the adjustment lower limit deviation value and the adjustment upper limit deviation value as the adjustment humidity deviation value. Adjust the ambient humidity to H2, calculate |H2-Hmin| as the lower limit deviation value and |H2-Hmax| as the upper limit deviation value. When H2 is greater than the upper limit threshold, |H2-Hmax|<|H2-Hmin|, and |H2-Hmax| is used as the humidity deviation value. When H2 is less than the lower limit threshold, |H2-Hmin|<|H2-Hmax|, and |H2-Hmin| is used as the humidity deviation value.

[0116] Figure 5 Schematic diagram of a module of a control device provided by an embodiment of the present invention. Figure 5As shown, this embodiment also provides a control device capable of executing the above-described dehumidification control method. The control device includes: an acquisition module 51 for acquiring the appropriate humidity range for the current season and the current ambient humidity; and a control module 52 for adjusting the air intake area of ​​the auxiliary air inlet 111 and the fan operating power based on the appropriate humidity range and the current ambient humidity. This control device can perform secondary auxiliary humidity adjustment on the basis of the primary dehumidification adjustment by adjusting the air intake area of ​​the auxiliary air inlet 111 and the fan operating power. This improves the humidity adjustment range, capability, accuracy, and intelligence of the dehumidifier, allowing the ambient humidity to quickly and accurately reach the appropriate humidity range for user comfort in the current season, thereby significantly improving user comfort and convenience.

[0117] The dehumidifier provided in this embodiment is capable of executing the above-mentioned dehumidification control method, specifically by controlling the driving position of the driving component on the sub-board 300 to adjust the blocking position of the sub-board 300 on the auxiliary air inlet 111, thereby adjusting the air inlet area of ​​the auxiliary air inlet 111; the dehumidifier has all the beneficial effects of the dehumidification control method, which will not be repeated here.

[0118] Optionally, in this embodiment, if Figure 6 As shown, the auxiliary air inlet 111 is located on the front panel 110 of the shell 100 and corresponds to the front side panel of the fan. Auxiliary air inlet channels are present between the left and right sides of both the dehumidification duct and the fan and the corresponding side panels of the shell 100, and the auxiliary air inlet channels connect the auxiliary air inlet 111 and the rear air duct opening. The outer wall of the dehumidification duct and the fan are located in the shell 100, and form an annular channel with the inner wall of the shell 100, wherein the auxiliary air inlet 111 is located at the front end of the annular channel, the rear air duct opening and the main air inlet are located at the front and rear sides of the rear end of the annular channel, then the annular channel is divided into two approximately symmetrical auxiliary air inlet channels on the left and right by the auxiliary air inlet 111 and the rear air duct opening; when the auxiliary air inlet 111 needs to be opened for auxiliary humidity adjustment, the control drive component drives the sub-board 300 to move relative to the auxiliary air inlet 111 to change its blocking area of ​​the auxiliary air inlet 111, and adjusts the air inlet area of ​​the auxiliary air inlet 111 accordingly; after the adjustment is completed, the fan operation will The suction in the dehumidification air duct is in a negative pressure state, and the dehumidification air duct generates a suction effect on the auxiliary air inlet channels on the left and right sides through the rear air duct opening. The ambient air flows into the shell 100 approximately in a direction perpendicular to the auxiliary air inlet 111 under the action of the internal and external pressure difference, and then contacts the front side panel of the fan and flows into the auxiliary air inlet channels on the corresponding side in the left and right directions under the guidance of the front side panel, and then flows through the auxiliary air inlet channel to the rear air duct opening in the front and back directions, and then flows into the dehumidification air duct through the rear air duct opening, and then enters the fan after the condensation and dehumidification treatment of the evaporator and the temperature recovery treatment of the condenser and finally flows back to the environment, thereby completing the humidity regulation of the environment.

[0119] Compared with the auxiliary air inlet 111 arranged on the left and right sides of the shell 100, the rear air duct opening will produce a suction effect on the auxiliary air inlet channels on the left and right sides. The airflow entering the shell 100 through the left and right auxiliary air inlets 111 will collide with the dehumidification air duct or the fan, and will flow in the front and rear directions respectively under the guidance of the rear air duct opening. The two airflows flowing backward in the auxiliary air inlet channels on the left and right sides can flow into the dehumidification air duct through the rear air duct opening, while the two airflows flowing forward will collide at the front end to generate a larger vortex, which will not only greatly reduce the effective regulation of the airflow by the auxiliary air inlet 111, but also generate greater noise pollution. The auxiliary air inlet 111 of the dehumidifier of this embodiment is arranged relative to the main air inlet and the air outlet in front and back, and corresponds to the position of the front side panel of the fan. On the basis of achieving the regulation of the ambient humidity, the airflow entering the interior of the shell 100 through the auxiliary air inlet 111 can fully and smoothly flow into the dehumidification air duct under the guiding effect of the front side panel and the drainage and diversion effect of the left and right auxiliary air inlet channels. It can not only ensure the effective regulation of the airflow volume by the air inlet area of ​​the auxiliary air inlet 111, and correspondingly ensure the effectiveness of the auxiliary humidity regulation of the dehumidifier and improve its dehumidification performance; it can also reduce noise pollution such as vortexes generated by air flow collision, thereby improving the silent effect of the dehumidifier and correspondingly improving the user's comfort.

[0120] In this embodiment, Figure 6 As shown, the exhaust port of the fan is located at the top, and the top plate 120 of the housing 100 is provided with an air outlet 121 corresponding to the exhaust port. The air outlet 121 is located at the top of the shell 100, the auxiliary air inlet 111 is located at the front panel 110, and the main air inlet is located at the back panel. When the dehumidifier is running and the auxiliary air inlet 111 is needed for auxiliary humidity adjustment, the air flows into the shell 100 through the auxiliary air inlet 111 on the front and rear sides of the shell 100 and the main air inlet, and then flows into the environment again through the top air outlet 121 after dehumidification and temperature recovery. The discharge area of ​​the air flow after dehumidification and the entry area of ​​the air flow that needs to be dehumidified are completely in two different areas, thereby reducing the area where the air outlet 121 is close to or the same as the main air inlet or auxiliary air inlet 111. The dehumidified air flow discharged through the air outlet 121 can flow back into the shell 100 under the suction action of the main air inlet or auxiliary air inlet 111, which will cause the dehumidifier to operate invalidly. Accordingly, it is ensured that the gas flowing in through the main air inlet and the auxiliary air inlet 111 is the gas that needs to be dehumidified, thereby ensuring that the dehumidifier effectively dehumidifies the environment.

[0121] Optionally, in this embodiment, if Figure 6As shown, the sub-plate 300 matches the auxiliary air inlet 111, and the sub-plate 300 is hinged to the edge of the auxiliary air inlet 111 via a first hinge axis. The driving end of the driving assembly is connected to the sub-plate 300, and is used to drive the sub-plate 300 to rotate around the axis of the first hinge axis. This is one of the specific forms of the sub-plate 300 adjusting the air inlet area of ​​the auxiliary air inlet 111. When in use, the driving assembly drives the sub-plate 300 to rotate around the first hinge axis, and changes the air inlet area of ​​the auxiliary air inlet 111 by adjusting the angle between the sub-plate 300 and the auxiliary air inlet 111. When the auxiliary air inlet 111 is not needed for auxiliary humidity adjustment, the driving assembly is controlled to drive the sub-plate 300 to rotate and block the auxiliary air inlet 111. At this time, the sub-plate 300 is embedded in the auxiliary air inlet 111, and the outer wall of the shell 100 has a high degree of flatness.

[0122] Specifically, in this embodiment, a first hinge axis is located at the top of the sub-plate 300. The driving end of the driving assembly abuts against the sub-plate 300, driving the sub-plate 300 to rotate about the axis of the first hinge axis. The rotational position of the sub-plate 300 includes a horizontal position. During use, the driving end of the driving assembly rotates the sub-plate 300 relative to the auxiliary air inlet 111 to adjust the angle between the sub-plate 300 and the auxiliary air inlet 111, thereby adjusting the air intake area of ​​the auxiliary air inlet 111. When the sub-plate 300 is approximately opened to its maximum angle, the air intake area of ​​the auxiliary air inlet 111 is maximized. When the sub-plate 300 is rotated to 90 degrees and is approximately horizontal, the sub-plate 300 can function as a horizontal tabletop for placing items such as mobile phones, thereby improving the functionality of the dehumidifier. When auxiliary humidity adjustment is no longer needed, the driving end of the driving assembly retracts, and the sub-plate 300 rotates downward under its own weight to a vertical position, thereby blocking the auxiliary air inlet 111. This results in a simple structure and convenient actuation.

[0123] In this embodiment, a USB charging port can also be provided on the front side panel. When the sub-board 300 is rotated to a horizontal position to assist in humidity adjustment or when the user requires a mobile phone holder, the horizontal sub-board 300 can be used as a shelf to place a mobile phone or other items. When the sub-board 300 is used as a mobile phone holder, the mobile phone can also be charged through the USB charging port, thereby further improving the functionality of the dehumidifier.

[0124] Specifically, in this embodiment, the front side panel is provided with a hinge seat, and the driving assembly includes a pushing frame and a driving member. The pushing frame is hinged to the hinge seat through a second hinge shaft, the second hinge shaft is parallel to the first hinge axis, and the pushing frame corresponds to the position of the sub-plate 300; the driving member is connected to the pushing frame, and is used to drive the pushing frame to rotate to drive the sub-plate 300 to rotate. This is one specific form of the driving component. The top of the sub-plate 300 is hinged to the top edge of the auxiliary air inlet 111 through the first hinge axis, and the top of the pushing frame is hinged to the front side plate through the second hinge axis. The first hinge axis is parallel to the second hinge axis, so the pushing frame is located inside the sub-plate 300 and is approximately parallel to the sub-plate 300; when it is necessary to adjust the air inlet area of ​​the auxiliary air inlet 111, the driving component can be started to drive the pushing frame to rotate around the second hinge axis. Accordingly, the pushing frame can push the sub-plate 300 outward from the inside of the sub-plate 300 to rotate around the first hinge axis, thereby realizing the adjustment of the rotation angle of the sub-plate 300; when no auxiliary humidity adjustment is required, the driving component drives the pushing frame to be approximately in a vertical state, and the sub-plate 300 is no longer pushed by the pushing frame, and thus rotates to an approximately vertical state under the action of its own gravity, and accordingly embeds and blocks the auxiliary air inlet 111.

[0125] Optionally, in this embodiment, the second hinge shaft is rotatably connected to the hinge seat, and the push frame is fixed to the second hinge shaft. A storage space is formed at the volute tongue of the fan volute, and the driving component includes a push rod motor and a connecting rod. The push rod motor is accommodated in the storage space, and the first end of the connecting rod is hinged to the driving end of the push rod motor and the second end is fixed to the second hinge shaft. The outer shell of the push rod motor is hinged to the volute. When the rotation angle of the sub-plate 300 needs to be adjusted, the driving length of the push rod of the push rod motor changes, and the corresponding driving connecting rod drives the second hinge shaft to rotate. The push frame rotates synchronously with the second hinge shaft, thereby driving the sub-plate 300 to rotate, thereby adjusting the air inlet area of ​​the auxiliary air inlet 111. At the same time, the push rod motor is installed in the storage space formed by the volute tongue, thereby fully utilizing the storage space, improving the compactness of the installation of the various components inside the housing 100, and reducing the obstruction and disturbance caused by the drive assembly to the air flow, thereby further improving the smoothness and quietness of the air flow, thereby improving the dehumidification effect and quietness of the dehumidifier.

[0126] Of course, in other embodiments, the second hinge shaft can also be fixed to the hinge seat, the pushing frame is rotatably connected to the second hinge shaft, the driving member includes a push rod motor, the outer shell of the push rod motor is hinged to the accommodating space of the volute, and the push rod end of the push rod motor is hinged to the pushing frame. By adjusting the telescopic length of the push rod to push the pushing frame to rotate around the second hinge shaft, the sub-plate 300 is pushed to rotate, thereby realizing the adjustment of the air inlet area of ​​the auxiliary air inlet 111.
