This application proposes a humidification module.

In the embodiment of the present application, as shown in FIGS. 1 to 5, the humidification module includes: a housing 100, a wet curtain 200, a heating element 300, and a damper 140. The housing 100 has an air duct 150 and communicates with the The first air outlet 113 and the second air outlet 114 of the air duct 150, the wet curtain 200 is installed on the housing 100, and is arranged corresponding to the first air outlet 113; the heating element 300 is installed on the shell Body 100, and located in the air duct 150; the damper 140 is provided with an avoiding groove 141, the damper 140 has an air supply station that covers the first air outlet 113, and covers the second outlet The humidification station of the air outlet 114, under the air supply station, the heating element 300 and the wet curtain 200 are located on the side of the air door 140 close to the first air outlet 113, and the heating element 300 is located In the avoidance groove 141. The humidification module described in this embodiment has two functions: normal air discharge and humidification. When the humidification module performs normal air discharge, the air door 140 is located at the air supply station, so that the air in the air duct 150 It is sent out from the second air outlet 114. When the humidification module performs humidification, the air door 140 is located at the humidification station, so that the wind in the air duct 150 can pass through the heating element 300 first, and then blow to all In the wet curtain 200, the airflow passes through the wet curtain 200, thereby bringing the moisture in the wet curtain 200 to the air, so as to increase the humidity of the air. The heating element 300 in this embodiment is arranged close to the wet curtain 200, so that the heating element 300 can not only heat the airflow in the air duct 150, but also effectively heat the wet curtain 200, which can increase the size of the wet curtain 200. 200 pairs of air humidification efficiency.

The position of the heating element 300 in the humidification module described in the technical solution of the present application is difficult to adjust due to the restriction of the installation space, which easily causes the distance between the heating element 300 and the wet curtain 200 to be too close, resulting in the humidification module when the humidification module is humidified. Too fast water loss, yellowing and aging due to high temperature. This embodiment adopts the structure in which the damper 140 is provided with the avoidance groove 141, so that when the damper 140 covers the first air outlet 113, the avoidance groove 141 can provide more installation space for the heating element 300, so that When the heating element 300 is installed, it can be installed at a position that keeps a longer distance from the wet curtain 200, so as to ensure the efficient humidification of the wet curtain 200 and prolong the service life.

Further, in this embodiment, the distance between the heating element 300 and the wet curtain 200 is at least 10 mm and not more than 60 mm. When the distance between the heating element 300 and the wet curtain 200 is too small, when the heating element 300 is heated, the temperature of the wet curtain 200 is likely to be too high and aging, and the service life of the wet curtain 200 is shortened. When the distance between the heating element 300 and the wet curtain 200 is too large, the heating element 300 can only increase the humidification efficiency by heating the airflow temperature in the air duct 150, and cannot directly affect the humidity through the heating element 300. The curtain 200 is heated to increase the humidification efficiency, and the increase in the humidification efficiency is limited, resulting in low humidification efficiency of the wet curtain 200. In this embodiment, the distance between the heating element 300 and the wet curtain 200 is set to be at least 10 mm and not more than 60 mm, which can not only ensure the good humidification efficiency of the wet curtain 200, but also prolong the service life of the wet curtain 200 .

Further, in this embodiment, as shown in FIG. 3 and FIG. 4, the extension direction of the heating element 300 and the wet curtain 200 are the same.

The extension direction of the heating element 300 and the wet curtain 200 are consistent, so that the heating element 300 has more surfaces facing the wet curtain 200, thereby improving the heating efficiency of the heating element 300 on the wet curtain 200. In order to improve the humidification efficiency of the wet curtain 200, it can also make the wet curtain 200 heat more uniformly, and avoid the local overheating and aging of the wet curtain 200. It can be understood that when the humidification module needs to improve the humidification efficiency, the temperature of the heating module is increased. The module is only partially facing the wet curtain 200, so in order to achieve the predetermined humidification efficiency, the heating module needs to increase the temperature higher, and the part of the wet curtain 200 opposite to the thermal module is prone to overheating and aging.

The area that can be exposed to the air is less; furthermore, the wet curtain 200 is arranged outside the air duct 150 to prevent dripping of the wet curtain 200 from flowing into the air duct 150.

Further, in this embodiment, as shown in FIGS. 1, 3, and 4, the wet curtain 200 covers the first air outlet 113, so that the damper 140 covers the second air outlet At 114 hours, the air flow in the air duct 150 needs to pass through the wet curtain 200 to flow out of the air duct 150, so that the wet curtain 200 can be fully utilized, which is beneficial to improve the humidification efficiency of the humidification module. Since the wind resistance when the wind passes through the wet curtain 200 is large, if there is a gap between the wet curtain 200 and the first air outlet 113, the air duct 150 blows toward the air flow of the first air outlet 113 , It is easy to bypass the wet curtain 200 and flow out from the gap, causing the wet curtain 200 to fail.

Further, in this embodiment, as shown in FIGS. 3 and 4, a grill 115 is provided between the wet curtain 200 and the heating element 300. Specifically, the grill 115 is arranged at the first air outlet 113, the wet curtain 200 and the heating element 300 are respectively located on both sides of the grill 115, and the grill 115 can avoid the wet curtain 200 It is in contact with the heating element 300.

Specifically, the damper 140 is under the air supply station that covers the first air outlet 113, and the middle of the damper 140 bulges away from the first air outlet 113, so that the middle distance of the damper 140 is The distance of the first air outlet 113 becomes longer, so that there is a larger installation space between the middle of the air door 140 and the first air outlet 113 for the heating element 300, which facilitates the adjustment of the heating element 300 to A more suitable position from the wet curtain 200. Forming the avoidance groove 141 by a bulge is beneficial to make the volume of the damper 140 small. Since the damper 140 is under the air supply station, the damper 140 is in the air duct 150, and the damper 140 The small volume is conducive to flowing out more air supply space to the air duct 150, thereby ensuring the air output of the second air outlet 114. The avoidance groove 141 in this embodiment is not limited to the above technical solution. In other embodiments, it is also possible that the damper is provided with a groove on the plate surface close to the first air outlet to form the avoidance groove.

At the same time, it also has the advantage of convenient installation of the damper 140. The damper 140 described in this embodiment is not limited to the above-mentioned installation method. In other embodiments, the damper may be slidably connected with the housing. Specifically, the air duct is provided with a sliding rail, and the The sliding rail extends from the first air outlet to the second air outlet, and the damper is slidably arranged in the sliding rail, which has the advantage of more convenient switching of the damper from the air supply station to the humidification station .

Further, in this embodiment, as shown in FIGS. 1, 3, and 4, the housing 100 includes an air outlet frame 110 forming part of the air duct 150, and one end of the air outlet frame 110 is provided with The second air outlet 114, the air outlet frame 110 has a first side plate 111 and a second side plate 112 adjacent to each other, the first side plate 111 is provided with the first air outlet 113, the The damper 140 is rotatably connected to the second side plate 112. The damper 140 is rotatably connected with the second side plate 112, so that more positions can be set aside on the first side plate 111 for opening the first air outlet 113, which is beneficial to lift the first side plate 112. The area of the air outlet 113 improves the humidification efficiency of the humidification module. The damper 140 in this embodiment is not limited to the above-mentioned installation scheme. In other embodiments, it may also be that the inner surface of the first side plate is convexly provided with two installation protrusions, and the installation protrusion is provided with a shaft.

Since the air-conditioning indoor unit adopts all the technical solutions of all the above-mentioned embodiments, it has at least the above-mentioned implementations. All the features brought about by the technical solution of the example will not be repeated here.

This application also proposes an air conditioner, which includes an air conditioner indoor unit. The specific structure of the air conditioner indoor unit refers to the above-mentioned embodiments. Since this air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least the above-mentioned embodiments. All the features brought about by the technical solution will not be repeated here. Specifically, the air conditioner further includes an air conditioner outdoor unit, and the air conditioner outdoor unit and the air conditioner indoor unit are connected by a refrigerant pipe.

This application also proposes a method for controlling the above-mentioned humidification module, as shown in FIG. 6, including the following steps:

S1 obtains indoor humidity data;

S2 compares the humidity data with a first preset humidity parameter, and after confirming that the humidity data is less than the first preset humidity parameter, controls the damper 140 to cover the second air outlet 114;

S3 controls the heating element 300 to work for a first preset time period;

S4 After confirming that the heating element 300 works for the first preset time period, control the heating element 300 to stop heating for the second preset time period;

S5 returns to the step of acquiring indoor humidity data after confirming that the heating element 300 stops heating for the second preset time period.

The humidification module in this embodiment also has a humidity sensor, a driving component, and an electric control box. The humidity sensor is configured to detect indoor humidity. The driving component is installed in the housing 100 and connected to the damper 140.

When the indoor humidity is lower than the first preset humidity, the experience is poor, and the humidity of the air needs to be increased by the humidification module. The humidification module can obtain indoor humidity data through a humidity sensor, and when the humidity data is lower than the first preset humidity, control the damper 140 to cover the second air outlet 114 so that the air duct 150 The air inside flows out from the first air outlet 113, and the air flow can pass through the wet curtain 200. Then, it is necessary to control the operation of the heating element 300 so that the humidification module enters the humidification mode. In order to avoid overheating of the wet curtain 200 caused by the continuous operation of the heating element 300, after the heating element 300 operates for a first preset period of time, it stops for a second preset period of time. Then continue to detect the indoor humidity. At this time, if the indoor humidity is greater than or equal to the first preset humidity parameter, the heating element 300 is controlled to stop heating, and the damper 140 is controlled to cover the first air outlet 113. The humidification mode stops humidification. If the indoor humidity is still lower than the first preset humidity parameter, the heating element 300 performs the next heating, and so on.

Generally, when the indoor temperature is high, the humidity in the air is high, so humidification is not required. Generally, when the indoor temperature is low, the humidity in the air is low, and further confirmation of the indoor humidity data is required.

The control method described in this embodiment is not limited to the above technical solutions. In other embodiments, the step of controlling the heating element 300 to work for the first preset time period described in S3 may also include: obtaining the first preset The difference between the humidity parameter and the humidity data is used to control the heating power of the heating element 300 according to the difference. For example, the first preset humidity parameter is 30% relative humidity, and the humidity data a is subtracted from 30% to obtain the difference b. When the difference b is larger, the heating power f of the heating element 300 is closer to the maximum power. w, the difference b is proportional to the heating power, and f=x·b·w can be used as a correction parameter. This control method can effectively prevent the heating element 300 from heating the wet curtain 200 with high power for a long time. It is beneficial to extend the service life of the wet curtain 200. Of course, the first preset humidity parameter may also be 35% relative humidity, 40% relative humidity, and so on.

The control method in this embodiment is not limited to the above technical solution. In other embodiments, it may also be that the humidity data is compared with the first preset humidity parameter in S2, and it is confirmed that the humidity data is less than the first preset humidity parameter. After a preset humidity parameter, the step of controlling the damper 140 to cover the second air outlet 114 further includes: comparing the humidity data with a second preset humidity parameter to confirm that the humidity data is greater than or equal to all After the second preset humidity parameter, the heating element 300 is controlled to stop heating, and the damper 140 is controlled to cover the first air outlet 113, and the second preset humidity parameter is greater than the first preset humidity parameter . The user usually has a comfortable humidity range. The range between the first preset humidity and the second preset humidity can be set to a comfortable humidity range. For example, the first preset humidity may be 30% relative humidity. 2. The preset humidity is 60% relative humidity. When the indoor humidity data is less than 30% relative humidity, the humidification module starts to humidify. As the humidification module works, the indoor humidity rises. When the indoor humidity data is detected When it is greater than 60%, the humidification is stopped. After the humidification is stopped, the humidity in the indoor air will slowly decrease, and the indoor can be kept in the comfortable range of 30% to 60% relative humidity for a long time, which is conducive to improving the customer experience . Of course, the first preset humidity can also be 40% relative humidity, the second preset humidity can also be 50% relative humidity, the first preset humidity can also be 25% relative humidity, and the second preset humidity can also be 55%. Relative humidity and so on.
