Because the air humidity is constantly changed, the air humidity is different in different regions, different environments, different seasons and the like.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the disclosed embodiments are merely exemplary of the invention, and are not intended to be exhaustive or exhaustive. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
In consideration of the above, in the related scheme, the rotary dehumidifier generally operates at a fixed rotation speed during use, and cannot monitor air humidity or change the speed of the rotary according to the humidity. Therefore, the rotating wheel of the rotary dehumidifier always runs at a fixed rotating speed, and when the humidity of inlet air is too high or too low, the rotating speed of the rotating wheel is insufficient or too high, so that the absorption capacity of the adsorbent on the rotating wheel to moisture in outdoor air is influenced, and the dehumidification capacity of the rotary dehumidifier is reduced. The scheme of the invention provides a control method of the rotary dehumidifier, which can change the speed according to the humidity, so as to realize that the rotating speed of the rotary dehumidifier is in different running conditions under different humidity environments, thereby better realizing the dehumidification effect.
According to an embodiment of the present invention, a method for controlling a rotary dehumidifier is provided, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method of the present invention. The rotary dehumidifier includes: a desiccant rotor 4 and a variable speed motor 5. And the variable speed motor 5 is used for driving the dehumidifying rotating wheel 4 to operate. A humidity detection unit is arranged between an inlet air filter screen on the outdoor air inlet side of the dehumidification rotary wheel 4 and an inlet air fan, the inlet air filter screen is a first filter screen 2, the inlet air fan is a fan 3, and the humidity detection unit is a humidity sensor 13. The humidity detection unit is used for detecting the humidity of air which flows through the air inlet fan and is behind the air inlet filter screen and flows through the air inlet filter screen, and the humidity is recorded as air inlet humidity (such as air inlet humidity D).
Specifically, fig. 4 is a schematic structural diagram of an embodiment of the rotary dehumidifier. In the rotary dehumidifier shown in fig. 4, the outdoor air 1 passes through the first filter 2 on the first air flow path to obtain the first air. The first air passes through the fan 3 and is delivered to the desiccant rotor 4. The humidity sensor 13 collects the humidity of the first air after the first filter screen 2, and then conveys the first air to the controller of the variable speed motor 5. The variable speed motor 5 can adjust the rotation speed of the desiccant rotor 4. The first air passes through the dehumidifying wheel 4 to obtain the second air. The second air passes through a second filter screen 6 to obtain dry fresh air 7. On the second air flow path, the fresh air 8 is regenerated and passes through the third filter 9 to obtain third air. The third air passes through the desiccant rotor 4 after passing through the heater 10, and the fourth air is obtained. The fourth air is processed by a processing fan 11 to obtain regenerated outlet air 12. Wherein the first and second air flow paths have opposite flow paths. In the example shown in fig. 4, a humidity sensor 13 is added to detect the humidity of the sucked outdoor air 1. The motor adopts a variable speed motor 5, and the rotating speed of the variable speed motor 5 can be changed according to the change of the humidity of the outdoor air 1 detected by the humidity sensor 13, so that the rotating speed of the dehumidifying rotating wheel 4 is changed.
As shown in fig. 1, in an aspect of the present invention, a method for controlling a rotary dehumidifier includes: step S110 to step S140.
In step S110, the inlet air humidity (e.g., inlet air humidity D) of the rotary dehumidifier is obtained.
In step S120, a humidity range in which the humidity of the inlet air of the rotary dehumidifier is within a set humidity range is determined according to the humidity of the inlet air of the rotary dehumidifier.
In some embodiments, the humidity interval of the set humidity range includes: the humidity control system comprises a first humidity interval, a second humidity interval, a third humidity interval, a fourth humidity interval and a fifth humidity interval. In the first humidity interval, the second humidity interval, the third humidity interval, the fourth humidity interval and the fifth humidity interval, the average humidity value of each humidity interval is reduced in sequence.
In step S120, a humidity interval in which the humidity of the inlet air of the rotary dehumidifier is within a set humidity range is determined according to the humidity of the inlet air of the rotary dehumidifier, and the determining process includes any one of the following humidity interval determining processes:
first humidity interval determination process: and if the humidity of the inlet air of the rotary dehumidifier is greater than or equal to a first set humidity, determining that the humidity interval of the inlet air of the rotary dehumidifier in the set humidity range is a first humidity interval.
The second humidity interval determination process: and if the humidity of the inlet air of the rotary dehumidifier is greater than or equal to a second set humidity and less than a first set humidity, determining that the humidity interval of the inlet air of the rotary dehumidifier in the set humidity range is a second humidity interval.
The third humidity interval determination process: and if the humidity of the inlet air of the rotary dehumidifier is greater than or equal to a third set humidity and less than a second set humidity, determining that the humidity interval of the inlet air of the rotary dehumidifier in the set humidity range is a third humidity interval.
A fourth humidity interval determination process: and if the inlet air humidity of the rotary dehumidifier is greater than or equal to a fourth set humidity and less than a third set humidity, determining that the humidity interval of the inlet air humidity of the rotary dehumidifier in the set humidity range is a fourth humidity interval.
A fifth humidity interval determination process: and if the humidity of the inlet air of the rotary dehumidifier is less than a fourth set humidity, determining that the humidity interval of the inlet air of the rotary dehumidifier in the set humidity range is a fifth humidity interval.
In the example shown in fig. 4, in order to monitor the humidity of the outdoor air 1 and change the transmission rotation speed of the variable speed motor 5 according to the humidity of the outdoor air 1, the humidity sensor 13 is installed behind the second filter screen 2, so that after the outdoor air 1 enters the rotary dehumidifier, the humidity sensor 13 can detect the humidity of the outdoor air 1 for the first time, and then determine the rotation speed adjustment information of the variable speed motor 5 according to the humidity of the outdoor air 1 according to the preset humidity control logic, so that the variable speed motor 5 adjusts the rotation speed according to the rotation speed adjustment information and drives the dehumidifying rotary 4 to operate.
Wherein, the humidity sensor 13 is installed behind the filter screen 2 to sense the humidity of the outdoor air, and the filter screen 2 does not change the humidity of the outdoor air after entering.
In the solution of the invention, the motor speed is fixed five steps, when the humidity varies within a range (e.g. D) 2 To D 3 Or D 3 To D 4 Etc.), the rotating speed of the variable speed motor is also corresponding to the gear number, and the rotating speed of the rotating wheel is also corresponding and cannot be continuously changed; in the related scheme, the gear number of the motor speed is not set, the gear number is changed according to the humidity change, when the humidity is changed in a small range, the rotating speed of the motor is also continuously changed, and relatively, certain influence on the service life of the motor is possibly caused. In addition, in the scheme of the invention, the heater gear shifting is additionally arranged, namely the temperature of the heater can change along with the gear number of the variable speed motor, so that the temperature of the heater can be indirectly changed according to the humidity, and the aim of better energy saving is fulfilled; and the heating plate in the related scheme has no related change, and the heating degree has no change, so that the energy-saving effect is poorer compared with the scheme of the invention.
In the rotary dehumidifier of the related scheme, the humidity sensor 13 is not arranged, and the dehumidification rotary wheel 4 is driven by a common motor instead of the variable speed motor 5, so that the dehumidification rotary wheel only has a fixed rotating speed, the rotating speed cannot be changed according to the change of the humidity, the dehumidification effect of the dehumidifier is influenced to a certain extent, and electric energy is wasted when the humidity is lower. According to the scheme of the invention, the humidity of the outside air (namely the outdoor air 1) can be monitored, so that the rotating speed of the variable speed motor 5 is changed, the rotating speed of the dehumidifying rotating wheel 4 is further changed, and the dehumidifying effect is better improved.
In step S130, a rotation speed gear of the variable speed motor 5 in a set rotation speed gear range is determined according to a humidity interval where the humidity of the intake air of the rotary dehumidifier is in the set humidity range, so as to obtain a current rotation speed gear of the variable speed motor 5.
In some embodiments, the setting of the speed range comprises: the set first gear rotating speed, the set second gear rotating speed, the set third gear rotating speed, the set fourth gear rotating speed and the set fifth gear rotating speed. Among the set first gear rotation speed, the set second gear rotation speed, the set third gear rotation speed, the set fourth gear rotation speed and the set fifth gear rotation speed, the rotation speed values of the set first gear rotation speed, the set second gear rotation speed, the set third gear rotation speed, the set fourth gear rotation speed and the set fifth gear rotation speed are increased in sequence.

Fig. 6 is a schematic diagram of a rotor regeneration logic of an embodiment of a rotor regeneration process of a rotor dehumidifier, and a process for adjusting a heating gear of a heater, which may be specifically referred to as the example shown in fig. 6.
In step S140, the variable-speed motor 5 is controlled to operate according to the current speed gear of the variable-speed motor 5, so that the variable-speed motor 5 drives the dehumidification rotor 4 to operate, thereby controlling the rotary dehumidifier.
According to the control method of the rotary dehumidifier capable of changing speed according to humidity, provided by the scheme of the invention, the speed-changing motor 5 is adopted, the humidity sensor 13 is additionally arranged, and the speed-changing motor 5 is indirectly controlled by the humidity sensor 13, so that the rotating speeds of the rotary wheels under different humidity conditions are changed, the purposes of humidity monitoring, variable rotating speeds of the rotary wheels, dehumidification efficiency improvement and energy and power saving are realized, and thus, the rotating speeds of the rotary wheels (namely the dehumidification rotary wheels 4) of the rotary dehumidifier under different humidity environments can be in different running states, and the dehumidification effect is better realized.
In some embodiments, in step S140, the variable-speed motor 5 drives the desiccant rotor 4 to operate, so as to implement a specific process of controlling the rotary dehumidifier, which is described in the following exemplary description.
With reference to the schematic flow chart of an embodiment of the method of the present invention shown in fig. 2, in which the variable speed motor 5 drives the desiccant rotor 4 to operate so as to implement control of the rotary dehumidifier, a specific process of the step S140, in which the variable speed motor 5 drives the desiccant rotor 4 to operate so as to implement control of the rotary dehumidifier, is further described, and includes: step S210 and step S220.
Step S210, the variable speed motor 5 drives the dehumidification rotating wheel 4 to operate, and control of a dehumidification process of the rotating wheel dehumidifier for dehumidifying based on outdoor air 1 to obtain dry fresh air 7 is achieved. And (c) a second step of,
step S220, under the condition that the fresh air 7 is obtained by dehumidification based on the outdoor air 1, the variable speed motor 5 is continuously driven to drive the dehumidification rotating wheel 4 to operate, and the control of the regeneration process of the rotating wheel dehumidifier for regenerating based on the indoor air to obtain the regenerated outlet air 12 is realized.
Specifically, the runner regeneration process of the runner dehumidifier comprises the following steps:
step 21, the adsorbing material (i.e. adsorbent) on the dehumidifying wheel 4 adsorbs moisture in the air sent by the fan 3, and the air becomes dry fresh air 7 and is sent into the room.
Step 22, the adsorption material on the dehumidification rotating wheel 4 becomes wet due to water absorption, meanwhile, due to the action of the fan 11, the regenerated fresh air 8 is also indoor air, passes through the second filter screen 9 and the heater 10 to become hot air meeting the requirements, and passes through the dehumidification rotating wheel 4, the high-temperature air enables the adsorbed water in the dehumidification rotating wheel 4 to be desorbed and discharged outdoors by the processing fan 11, so that the dehumidification rotating wheel 4 recovers the moisture absorption function to complete the regeneration function.
The moisture absorption process of the desiccant rotor 4 shown in fig. 5 and the regeneration process of the desiccant rotor 4 shown in fig. 6 are simultaneously completed, the desiccant rotor 4 is continuously rotated, and the above-mentioned dehumidification process and regeneration process are repeatedly performed, thereby ensuring a continuous and stable dehumidification state of the rotary dehumidifier.
In the solution of the present invention, the variable speed motor 5 can change the rotation speed according to the difference of the inlet air humidity D, and the rotation speed of the variable speed motor 5 is increased when the inlet air humidity D is high, so that the absorption and regeneration period of the adsorbent on the desiccant rotor 4 becomes shorter. When the humidity D of the intake air is low, the rotation speed of the variable speed motor 5 is decreased, and the period of the adsorption and regeneration of the adsorbent on the desiccant rotor 4 is increased. Compared with the rotary dehumidifier of the related scheme, the scheme of the invention can change the rotating speed of the rotary wheel according to the humidity, and the adjustment degrees of the rotating speeds of the dehumidification rotary wheels 4 are different according to the humidity D degree of the inlet air, thereby achieving better dehumidification effect and reducing the waste of electric energy.
According to the rotary dehumidifier capable of changing speed according to humidity, the humidity sensor is added to effectively monitor the humidity of inlet air, the speed change motor is added and is associated with the humidity sensor, and the rotating speed can be changed according to the humidity. Therefore, the variable-speed motor is adopted, the humidity sensor is additionally arranged, the rotating speed of the rotating wheel can be changed when the humidity changes in different regions, different seasons and different environments, the rotating speed of the rotating wheel of the rotary dehumidifier can be in different running states in different humidity environments, and the dehumidification effect can be better realized. When the humidity is high, the variable speed motor drives the rotating wheel to run at a high speed, the regeneration speed of the adsorbent is high, and the effective dehumidification capacity of the dehumidifier is enhanced. When the humidity is low, the rotating speed of the variable speed motor is reduced, the regeneration speed of the adsorbing material is reduced, the contact time with air is prolonged, moisture can be absorbed more fully, meanwhile, the energy consumption is reduced due to the reduction of the rotating speed, the waste of energy caused by the fixation of the rotating speed is effectively reduced, and therefore the dehumidification effect can be achieved more efficiently and more efficiently.
By adopting the technical scheme of the embodiment, the humidity sensor is arranged on the air outlet side of the air inlet filter screen (such as the first filter screen 2) of the rotary dehumidifier, the dehumidifying rotary wheel 4 is driven to operate by the variable speed motor 5, different rotating speed gears of the variable speed motor 5 are adjusted according to different humidity degrees of inlet air humidity detected by the humidity sensor, and the corresponding adjustment of the operating rotating speed of the initial rotary wheel 4 according to the inlet air humidity detected by the humidity sensor is realized, so that the absorbing capacity of the absorbent on the rotary wheel to moisture in outdoor air is ensured by adjusting the rotating speed of the rotary wheel of the rotary dehumidifier according to the inlet air humidity, and the dehumidifying capacity of the rotary dehumidifier is favorably improved.

Specifically, fig. 4 is a schematic structural diagram of an embodiment of a rotary dehumidifier. In the rotary dehumidifier shown in fig. 4, the outdoor air 1 passes through the first filter 2 on the first air flow path to obtain the first air. The first air passes through the fan 3 and is then delivered to the desiccant rotor 4. The humidity sensor 13 collects the humidity of the first air after the first filter screen 2, and then conveys the first air to the controller of the variable speed motor 5. The variable speed motor 5 can adjust the rotation speed of the desiccant rotor 4. The first air passes through the dehumidifying wheel 4 to obtain the second air. The second air passes through a second filter screen 6 to obtain dry fresh air 7. On the second air flow path, fresh air 8 is regenerated, and third air is obtained after passing through a third filter screen 9. The third air passes through the heater 10 and then passes through the desiccant rotor 4 to obtain fourth air. The fourth air is processed by a processing fan 11 to obtain regenerated outlet air 12. Wherein the first and second air flow paths have opposite flow paths. In the example shown in fig. 4, a humidity sensor 13 is added to detect the humidity of the sucked outdoor air 1. The motor adopts a variable speed motor 5, and the rotating speed of the variable speed motor 5 can be changed according to the change of the humidity of the outdoor air 1 detected by the humidity sensor 13, so that the rotating speed of the dehumidifying rotary wheel 4 is changed.

the control unit 104 is specifically configured to continue to make the variable speed motor 5 drive the dehumidification rotating wheel 4 to operate under the condition that the fresh dry air 7 is obtained by dehumidification based on the outdoor air 1, so as to control the regeneration process of the rotating wheel dehumidifier that the regeneration based on the indoor air is performed to obtain the regenerated outlet air 12. The specific functions and processes of the control unit 104 are also referred to in step S220.
Specifically, the runner regeneration process of the runner dehumidifier comprises the following steps:
in step 21, the adsorption material (i.e. adsorbent) on the dehumidification rotating wheel 4 can adsorb moisture in the air sent by the fan 3, and the moisture is changed into dry fresh air 7 which is sent into a room.
Step 22, the adsorption material on the dehumidification rotating wheel 4 becomes wet due to water absorption, meanwhile, due to the action of the fan 11, the regenerated fresh air 8 is also indoor air, passes through the second filter screen 9 and the heater 10 to become hot air meeting the requirements, and passes through the dehumidification rotating wheel 4, the high-temperature air enables the adsorbed water in the dehumidification rotating wheel 4 to be desorbed and discharged outdoors by the processing fan 11, so that the dehumidification rotating wheel 4 recovers the moisture absorption function to complete the regeneration function.
The moisture absorption process of the desiccant rotor 4 shown in fig. 5 and the regeneration process of the desiccant rotor 4 shown in fig. 6 are simultaneously completed, the desiccant rotor 4 is continuously rotated, and the above-mentioned dehumidification process and regeneration process are repeatedly performed, thereby ensuring a continuous and stable dehumidification state of the rotary dehumidifier.
In the solution of the present invention, the variable speed motor 5 can change the rotation speed according to the difference of the inlet air humidity D, and the rotation speed of the variable speed motor 5 is increased when the inlet air humidity D is high, so that the absorption and regeneration period of the adsorbent on the desiccant rotor 4 becomes shorter. When the humidity D of the intake air is low, the rotation speed of the variable speed motor 5 is reduced, and the period of the adsorption and regeneration of the adsorbent on the desiccant rotor 4 is prolonged. Compared with the rotary dehumidifier of the related scheme, the scheme of the invention can change the rotating speed of the rotary wheel according to the humidity, and the adjustment degrees of the rotating speeds of the dehumidification rotary wheels 4 are different according to the humidity D degree of the inlet air, thereby achieving better dehumidification effect and reducing the waste of electric energy.

When the humidity is high, the variable speed motor drives the rotating wheel to run at a high speed, the adsorbent regeneration speed is high, and the effective dehumidification capacity of the dehumidifier is enhanced. When the humidity is low, the rotating speed of the variable speed motor is reduced, the regeneration speed of the adsorbing material is reduced, the contact time with air is prolonged, moisture can be absorbed more fully, meanwhile, the energy consumption is reduced due to the reduction of the rotating speed, and the waste of energy caused by the fixation of the rotating speed is effectively reduced, so that the dehumidifying effect can be achieved more efficiently and more efficiently.
