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 specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Considering, in the related scheme, the rotary dehumidifier generally works at a fixed rotation speed in the use process, and cannot monitor the air humidity and change the rotary speed according to the humidity. Therefore, the rotating wheel of the rotating wheel dehumidifier always operates at a fixed rotating speed, and when the humidity of the inlet air is too high or too low, the rotating speed of the rotating wheel is insufficient or too high, the absorbing capacity of the adsorbent on the rotating wheel to moisture in the outdoor air is affected, and the dehumidifying capacity of the rotating wheel dehumidifier is reduced. According to the scheme, the control method of the rotary dehumidifier capable of performing speed change according to humidity is provided, so that the rotary dehumidifier can achieve the effect that the rotating speed of the rotary dehumidifier is in different running conditions under different humidity environments, and therefore the dehumidification effect is better achieved.

According to an embodiment of the present invention, a control method of a rotary dehumidifier is provided, and a flow chart of an embodiment of the method of the present invention is shown in fig. 1. The rotary dehumidifier includes: a dehumidifying rotating wheel 4 and a variable speed motor 5. The variable speed motor 5 is used for driving the dehumidifying rotating wheel 4 to operate. A humidity detection unit is arranged between an air inlet filter screen such as the first filter screen 2 and an air inlet fan such as the fan 3 on the outdoor air inlet side of the dehumidifying rotating wheel 4, and a humidity detection unit such as the humidity sensor 13. The humidity detection unit is configured to detect the humidity of air after the outdoor air 1 flows through the intake filter screen and before flowing through the intake fan, and record the humidity as intake air humidity (e.g., intake air humidity D).

Specifically, fig. 4 is a schematic structural diagram of an embodiment of a rotary dehumidifier. In the rotary dehumidifier shown in fig. 4, on the first air circulation path, the outdoor air 1 passes through the first filter 2 to obtain the first air. The first air is sent to the dehumidifying rotor 4 after passing through the fan 3. The humidity sensor 13 collects the humidity of the first air after the first filter screen 2, and then sends the humidity to the controller of the variable speed motor 5. The variable speed motor 5 is capable of adjusting the rotational speed of the desiccant rotor 4. The first air passes through the dehumidifying rotating 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 the third air is obtained after passing through the third filter screen 9. The third air passes through the dehumidifying rotor 4 after passing through the heater 10, and fourth air is obtained. The fourth air is treated by a blower 11 to obtain regenerated air outlet 12. Wherein the first air flow path and the second air flow path are opposite in flow path. 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 the 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 the solution of the present invention, the control method of the rotary dehumidifier includes: step S110 to step S140.

At step S110, the intake air humidity (e.g., intake air humidity D) of the rotary dehumidifier is obtained.

At step S120, a humidity interval in which the inlet air humidity of the rotary dehumidifier is within a set humidity range is determined according to the inlet air humidity of the rotary dehumidifier.

In some embodiments, the humidity interval of the set humidity range includes: a first humidity interval, a second humidity interval, a third humidity interval, a fourth humidity interval, and a fifth humidity interval. Wherein, 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 sequentially reduced.

In step S120, according to the intake air humidity of the rotary dehumidifier, a humidity interval in which the intake air humidity of the rotary dehumidifier is located in a set humidity range is determined, including any one of the following humidity interval determining processes:

First humidity interval determination procedure: if the inlet air humidity of the rotary dehumidifier is greater than or equal to the first set humidity, determining that a humidity interval in which the inlet air humidity of the rotary dehumidifier is in the set humidity range is a first humidity interval.

The second humidity interval determining process: if the inlet air humidity of the rotary dehumidifier is greater than or equal to the second set humidity and smaller than the first set humidity, determining that the humidity interval where the inlet air humidity of the rotary dehumidifier is in the set humidity range is the second humidity interval.

Third humidity interval determination process: if the inlet air humidity of the rotary dehumidifier is greater than or equal to the third set humidity and smaller than the second set humidity, determining that the humidity interval where the inlet air humidity of the rotary dehumidifier is in the set humidity range is the third humidity interval.

Fourth humidity interval determination process: if the inlet air humidity of the rotary dehumidifier is greater than or equal to the fourth set humidity and smaller than the third set humidity, determining that the humidity interval where the inlet air humidity of the rotary dehumidifier is in the set humidity range is the fourth humidity interval.

Fifth humidity interval determination process: and if the inlet air humidity of the rotary dehumidifier is smaller than the fourth set humidity, determining that the humidity interval in which the inlet air humidity of the rotary dehumidifier is 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 rotation speed of the transmission of the variable speed motor 5 according to the humidity of the outdoor air 1, the humidity sensor 13 is installed after the first 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 at the first time, and then determine the rotation speed adjustment information of the variable speed motor 5 according to the preset humidity control logic according to the humidity of the outdoor air 1, so that the variable speed motor 5 adjusts the rotation speed according to the rotation speed adjustment information and drives the dehumidifying rotary wheel 4 to operate.

Wherein, the humidity sensor 13 is arranged 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 incoming outdoor air.

In the scheme of the invention, the motor speed is five fixed gears, and when the humidity changes in a range (for example, D ₂ to D ₃ or D ₃ to D ₄, etc.), the rotating speed of the variable speed motor is also the corresponding gear number, and the rotating speed of the rotating wheel is also corresponding and does not continuously change; in the related scheme, the number of the motor speed is not set according to the change of the humidity, and when the humidity changes in a small range, the motor speed also continuously changes, so that the service life of the motor is relatively likely to be affected to some extent. In addition, in the scheme of the invention, the gear shift of the heater is newly added, namely the temperature of the heater can be changed along with the gear shift number of the variable speed motor, so that the temperature of the heater is indirectly changed according to the humidity, and the aim of better energy conservation is achieved; in the related scheme, the heating plate has no related change, the heating degree has no change, and compared with the scheme of the invention, the energy-saving effect is poorer.

In the related scheme, the rotary dehumidifier has no humidity sensor 13, and the dehumidifying rotary wheel 4 is driven by a common motor instead of the variable speed motor 5, so that the dehumidifying rotary wheel has only a fixed rotating speed, the rotating speed cannot be changed according to the change of humidity, the dehumidifying effect of the dehumidifier is affected to a certain extent, and the electric energy is wasted when the humidity is lower. By adopting 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.

At step S130, according to the humidity range where the humidity of the intake air of the rotary dehumidifier is in the set humidity range, the rotational speed gear of the variable speed motor 5 in the set rotational speed gear range is determined, and the current rotational speed gear of the variable speed motor 5 is obtained.

In some embodiments, the setting the rotational speed range includes: a set first gear rotational speed, a set second gear rotational speed, a set third gear rotational speed, a set fourth gear rotational speed, and a set fifth gear rotational speed. Wherein, among the set first gear rotational speed, the set second gear rotational speed, the set third gear rotational speed, the set fourth gear rotational speed and the set fifth gear rotational speed, the rotational speed values of the set first gear rotational speed, the set second gear rotational speed, the set third gear rotational speed, the set fourth gear rotational speed and the set fifth gear rotational speed are sequentially increased.

In step S130, according to the humidity range where the humidity of the intake air of the rotary dehumidifier is in the set humidity range, the rotational speed gear of the variable speed motor 5 in the set rotational speed gear range is determined, and the current rotational speed gear of the variable speed motor 5 is obtained, which includes any one of the following rotational speed gear adjustment processes:

The first rotational speed gear adjusting process comprises the following steps: and if the humidity interval where the inlet air humidity of the rotary dehumidifier is in the set humidity range is the first humidity interval, determining that the rotating speed gear of the variable speed motor 5 in the set rotating speed gear range is the set five-gear rotating speed, and obtaining the current rotating speed gear of the variable speed motor 5.

The second rotational speed gear adjusting process comprises the following steps: and if the humidity interval where the inlet air humidity of the rotary dehumidifier is in the set humidity range is the second humidity interval, determining that the rotating speed gear of the variable speed motor 5 in the set rotating speed gear range is the set four-gear rotating speed, and obtaining the current rotating speed gear of the variable speed motor 5.

The third rotational speed gear adjusting process comprises the following steps: and if the humidity interval where the inlet air humidity of the rotary dehumidifier is in the set humidity range is the third humidity interval, determining that the rotating speed gear of the variable speed motor 5 in the set rotating speed gear range is the set three-gear rotating speed, and obtaining the current rotating speed gear of the variable speed motor 5.

The fourth rotational speed gear adjusting process comprises the following steps: and if the humidity interval where the inlet air humidity of the rotary dehumidifier is in the set humidity range is the fourth humidity interval, determining that the rotating speed gear of the variable speed motor 5 in the set rotating speed gear range is the set second gear rotating speed, and obtaining the current rotating speed gear of the variable speed motor 5.

Fifth rotational speed gear adjusting process: and if the humidity interval where the inlet air humidity of the rotary dehumidifier is in the set humidity range is the fifth humidity interval, determining that the rotating speed gear of the variable speed motor 5 in the set rotating speed gear range is the set first gear rotating speed, and obtaining the current rotating speed gear of the variable speed motor 5.

Specifically, fig. 5 is a schematic diagram of air dehumidification logic of an embodiment of an air dehumidification process of a rotary dehumidifier. As shown in fig. 5, the air dehumidifying process of the rotary dehumidifier includes:

step 11, after the rotary dehumidifier is started, the outdoor air 1 enters the rotary dehumidifier. The humidity of the outdoor air 1 entering the rotary dehumidifier is detected by a humidity sensor 13, and the inlet air humidity D is obtained.

FIG. 6 is a schematic diagram of the regeneration logic of the rotor in one embodiment of the rotor regeneration process of the rotary dehumidifier, and the adjustment of the heater heating gear is specifically shown in FIG. 6.

At step S140, the variable speed motor 5 is controlled to operate according to the current rotational speed gear of the variable speed motor 5, so that the variable speed motor 5 drives the dehumidifying rotor 4 to operate, thereby realizing control of the rotor dehumidifier.

According to the control method of the rotary dehumidifier capable of performing speed change according to humidity, the speed change motor 5 is adopted, the humidity sensor 13 is added, and the speed change motor 5 is indirectly controlled by the humidity sensor 13, so that the rotating speed of the rotary wheel under different humidity conditions is changed, the purposes of humidity monitoring, changeable rotating speed of the rotary wheel, dehumidifying efficiency improvement, energy saving and electricity saving are achieved, and therefore the rotating speed of the rotary wheel (namely the dehumidifying rotary wheel 4) of the rotary dehumidifier under different humidity environments can be under different running conditions, and the dehumidifying effect is better achieved.

In some embodiments, in step S140, the variable speed motor 5 is caused to drive 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.

In the following, referring to fig. 2, a flowchart of an embodiment of the method of the present invention for driving the variable speed motor 5 to operate the desiccant rotor 4 to control the rotary dehumidifier is further described, where in step S140, a specific process for driving the variable speed motor 5 to operate the desiccant rotor 4 to control the rotary dehumidifier includes: step S210 and step S220.

Step S210, enabling the variable speed motor 5 to drive the dehumidifying rotating wheel 4 to operate, so as to realize the control of the dehumidifying process of the rotating wheel dehumidifier based on the outdoor air 1 to obtain the dry fresh air 7. And

Specifically, the rotating wheel regeneration process of the rotating wheel dehumidifier comprises the following steps:

In step 21, the absorbent (i.e. adsorbent) on the dehumidifying rotor 4 will absorb the moisture in the air sent by the fan 3, and become dry fresh air 7, and send into the room.

In step 22, the absorbent material on the dehumidifying rotating wheel 4 becomes wet due to water absorption, meanwhile, due to the effect of the upper fan 11, the regenerated fresh air 8, namely the indoor air, passes through the second filter screen 9 and then the heater 10 to become hot air reaching the requirement, then passes through the dehumidifying rotating wheel 4, and the high-temperature air enables the absorbed moisture in the dehumidifying rotating wheel 4 to be desorbed and discharged outside by the processing fan 11, so that the dehumidifying 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 finished, the desiccant rotor 4 is continuously rotated, and the above-mentioned dehumidification process and regeneration process are repeatedly performed, thereby ensuring that the desiccant rotor dehumidifier is continuously in a stable dehumidification state.

In the scheme of the invention, the rotating speed of the variable speed motor 5 can be changed according to the different humidity D of the inlet air, and when the humidity D of the inlet air is high, the rotating speed of the variable speed motor 5 is also increased, so that the period of water absorption and regeneration of the adsorbent on the dehumidifying rotating wheel 4 becomes shorter. Conversely, when the intake air humidity D is low, the rotation speed of the variable speed motor 5 decreases, and the period of water absorption and regeneration of the adsorbent on the desiccant rotor 4 increases. 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 degree of the rotating speed of the dehumidifying rotary wheel 4 is different when the humidity D degree of the inlet air is different, so that a better dehumidifying effect is achieved, and the waste of electric energy can be reduced.

According to the scheme provided by the invention, the rotating dehumidifier capable of changing speed according to humidity is provided with the humidity sensor to effectively monitor the humidity of the inlet air, and the rotating speed can be changed according to the humidity by adding the speed-changing motor and being associated with the humidity sensor. Like this, adopted variable speed motor, increased humidity transducer, can realize when humidity changes in different areas, different seasons, different environment, the change of runner rotational speed can realize that the rotational speed of runner dehumidifier runner is in different running conditions under the different humidity environment, realizes dehumidification effect better. When the humidity is high, the variable speed motor drives the rotating wheel to run at a higher speed, the adsorbent regeneration speed is high, and the effective dehumidification capability of the dehumidifier is enhanced. When the humidity is low, the rotating speed of the variable speed motor is also reduced, the regeneration speed of the adsorption material is reduced, the contact time with air is prolonged, the moisture can be absorbed more fully, meanwhile, the energy consumption is reduced due to the reduction of the rotating speed, the energy waste caused by the fixation of the rotating speed is effectively reduced, and therefore, the dehumidification effect can be achieved more effectively and in a more energy-saving manner.

Adopt the technical scheme of this embodiment, through setting up humidity transducer at the air intake filter screen (like first filter screen 2) of rotary dehumidifier's air-out side, and drive dehumidification runner 4 operation through variable speed motor 5, according to the different humidity degree of air inlet humidity that humidity transducer detected, the different rotational speed gears of adjustment variable speed motor 5, realize according to the corresponding regulation of air inlet humidity that humidity transducer detected to the operation rotational speed of initial runner 4, thereby, through the rotational speed of the runner according to air inlet humidity regulation rotary dehumidifier, guarantee the absorbing capacity of adsorbent on the runner to moisture in the outside air, be favorable to promoting the dehumidification ability of rotary dehumidifier.
