[0039] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only some, not all, of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0040] Example 1

[0041] This embodiment provides an intelligent dust reduction control method that can quickly and effectively filter dust from the air through humidification and dust removal. This method can be applied to air supply equipment that includes at least two air outlets, including an outlet and a return air outlet. Specifically, each air outlet can function as either an outlet or a return air outlet. Exemplarily, the air supply equipment can be an air conditioner, such as a ducted air conditioner.

[0042] Figure 1 This is a flow chart of the dust control method provided in Example 1 of the present invention. Figure 1 As shown, the method includes the following steps:

[0043] S101, detecting designated parameters of a target area.

[0044] S102: If the specified parameters meet the preset conditions, the humidifier is turned on to control the air outlet of the first air outlet and the air return of the second air outlet. If the specified parameters do not meet the preset conditions, the steps of detecting the parameters and determining whether the parameters meet the preset conditions are continued.

[0045] The humidifying device sprays water mist through the first air outlet, the first air outlet is set at a higher position than the second air outlet, and the second air outlet is provided with a dust filtering device, which can specifically be a filter. The first air outlet and the second air outlet belong to the at least two air outlets, and the first air outlet and the second air outlet are located in the same target area. The first air outlet and the second air outlet are connected through an air duct. For example, the first air outlet can be set in the upper space of the target area, and the second air outlet can be set in the lower space of the target area, or the first air outlet is located on the side of the air duct machine, and the second air outlet is located at the bottom of the air duct machine. This embodiment starts from the perspective of atomization humidification and realizes the intelligent filtering effect of upper air outlet humidification and lower return air dust removal in the air supply equipment.

[0046] The dust reduction control method of the embodiment of the present invention is based on the upper and lower air outlets. When the specified parameters meet the preset conditions, the humidification device is turned on and the wind direction of the relevant air outlet is controlled, so that the water mist sprayed from the first air outlet is evenly distributed in the air of the target area. During the humidification process, the dust particles in the air are effectively attached and sink, and then the return air is filtered and dust removed through the second air outlet. It can quickly and effectively filter the dust in the air, reduce air impurities, improve air quality, enhance the dust filtering effect, and give users a more comfortable experience.

[0047] In this embodiment, the specified parameters include ambient humidity and / or air dust content. Before activating the humidifier, the method further includes: determining whether the specified parameters meet preset conditions. Specifically, determining whether the ambient humidity is less than a preset humidity; if so, determining that the ambient humidity meets the corresponding humidification condition; and / or determining whether the air dust content is greater than or equal to a preset dust content; if so, determining that the air dust content meets the corresponding dust removal condition. The preset humidity may be an optimal humidity.

[0048] When the designated parameter is ambient humidity, if the ambient humidity is less than the preset humidity, it is determined that the ambient humidity meets the corresponding humidification condition (that is, the designated parameter meets the preset condition), then the humidification device is turned on and the first air outlet and the second air outlet are controlled to output air; if the ambient humidity is greater than or equal to the preset humidity, it is determined that the ambient humidity does not meet the corresponding humidification condition (that is, the designated parameter does not meet the preset condition), no humidification is required, and the ambient humidity continues to be detected and judged.

[0049] When the designated parameter is the dust content in the air, if the dust content in the air is greater than or equal to the preset dust content, it is determined that the dust content in the air meets the corresponding dust removal conditions (that is, the designated parameter meets the preset conditions), and the humidification device is turned on and the air outlet of the first air outlet and the air return of the second air outlet are controlled; if the dust content in the air is less than the preset dust content, it is determined that the dust content in the air does not meet the corresponding dust removal conditions (that is, the designated parameter does not meet the preset conditions), and there is no need to perform dust removal after humidification, and the dust content in the air continues to be detected and judged.

[0050] When the designated parameters are ambient humidity and air dust content, if at least one of the ambient humidity and air dust content meets the corresponding condition (i.e., the ambient humidity meets the corresponding humidification condition and / or the air dust content meets the corresponding dust removal condition), the designated parameter is determined to meet the preset condition; if the ambient humidity does not meet the corresponding humidification condition and the air dust content does not meet the corresponding dust removal condition, the designated parameter is determined to not meet the preset condition. The detection and determination of dust content and ambient humidity do not distinguish between the order of detection and determination and can be performed simultaneously.

[0051] When the ambient humidity and / or dust content in the air meet the corresponding preset conditions, it means that the target area needs humidification and / or dust removal. Then, the humidification and dust removal mode is entered, the humidification device is turned on, and the air outlet is controlled to be discharged from the first air outlet and the air is returned from the second air outlet. Humidification and then dust removal are performed. The upper air outlet humidification and lower return air dust removal modes are triggered with simple and reliable parameters to quickly and effectively filter the air dust.

[0052] In this embodiment, the designated parameter can be detected at a preset timing, wherein the preset timing includes: when the ambient temperature of the target area reaches the set temperature for the first time after the air supply device is turned on, or when the humidifier is in the off state for a first preset time period during the operation of the air supply device. After the air supply device is turned on and stable, or when the humidifier has been off for a first preset time period, the designated parameter is detected, thereby initiating the determination process of whether to perform humidification and dust removal, and timely performing humidification and dust removal on the target area.

[0053] After turning on the humidifier, the method further includes: detecting the specified parameter once every second preset time interval; if the specified parameter does not meet the preset condition, turning off the humidifier; if the specified parameter meets the preset condition, keeping the humidifier turned on. In this embodiment, the specified parameter is periodically detected while the humidifier is turned on. If the specified parameter does not meet the preset condition, indicating that humidification and dust removal are not currently required, the humidifier can be turned off in a timely manner to avoid excessive humidification. Of course, the specified parameter can also be detected in real time.

[0054] While the humidifier is running, it can monitor the ambient humidity of the target area in real time or at regular intervals. If the ambient humidity in the target area is greater than or equal to a preset threshold, it indicates that the humidification may be excessive and the humidifier needs to be turned off, stopping the humidification and dust removal mode to avoid excessive humidification causing discomfort to the user. The preset threshold is greater than the preset humidity.

[0055] In an optional embodiment, the above method may further include: in response to a user setting instruction, turning on or off the humidifying device, and controlling the first air outlet and the second air outlet accordingly. When the air conditioner is running, if the current dust reduction level is not enough or the humidification is excessive, the user can perform manual operation according to his or her own needs, and manually choose to turn on or off the humidifying device to meet his or her own cleaning needs. For example, the user can input user setting instructions through an input device (touch screen, button or remote control, etc.). The air supply device itself controls the first air outlet and the second air outlet accordingly as the humidifying device is turned on or off. Specifically, if the humidifying device is turned on, the first air outlet and the second air outlet are controlled to output air. If the humidifying device is turned off, the first air outlet and the second air outlet are automatically adjusted according to the equipment operation mode. For example, the current wind direction can be maintained to continue operation, or the wind direction can be switched according to the temperature control requirements.

[0056] Specifically, controlling the outflow of air from the first air outlet and the return of air from the second air outlet includes: determining the current wind direction of the first and second air outlets; if the current wind direction of the first air outlet is not outflow, adjusting the wind direction of the first air outlet to outflow; if the current wind direction of the second air outlet is not return, adjusting the wind direction of the second air outlet to return. This allows the wind direction of the first and second air outlets to be adjusted in conjunction with the activation of the humidifier, achieving a mode of humidification of the upper air outlet and dust removal of the lower return air.

This device can be implemented using software and / or hardware and can generally be integrated into the controller of the air supply equipment.

[0066] Optionally, the detection module 21 is further used to: after turning on the humidifying device, detect the specified parameter once every second preset time period; accordingly, the first control module 22 is further used to: turn off the humidifying device if the specified parameter does not meet the preset condition.

[0070] The above device can execute the method provided by the embodiment of the present invention, and has the functional modules and beneficial effects corresponding to the execution method. For technical details not fully described in this embodiment, please refer to the method provided by the embodiment of the present invention.

[0071] Example 3

[0072] This embodiment provides an air supply device, characterized in that the air supply device includes at least two air outlets, the at least two air outlets include an air outlet and an air return outlet, and the air supply device also includes: a humidifying device, a dust filtering device and the dust reduction control device described in the above embodiment.

[0073] The air supply equipment of this embodiment is based on the air outlets set up above and below. When the specified parameters meet the preset conditions, the humidification device is turned on and the wind direction of the relevant air outlet is controlled, so that the water mist sprayed from the first air outlet is evenly distributed to the air in the target area. During the humidification process, the dust particles in the air are effectively attached and sunk, and then the return air is filtered and dust removed through the second air outlet. It can quickly and effectively filter the dust in the air, reduce air impurities, improve air quality, enhance the dust filtering effect, and give users a more comfortable experience.

[0074] The air supply device further includes: a humidity detection device disposed at the first air outlet; and / or a dust content detection device disposed at the first air outlet. The humidity detection device and the dust content detection device can effectively detect the ambient humidity and the dust content in the air, serving as a basis for intelligent automatic control of humidification and dust removal, thereby providing a comfortable environment for the user.

[0075] In an optional embodiment, the humidifying device comprises:

[0076] The atomizing nozzle is set at the first air outlet, spraying the pressurized water flow into the target area and scattering it in the form of mist;

[0077] a water reservoir connected to the atomizing nozzle via a pipeline, and used to provide water to the atomizing nozzle;

[0078] An atomizing switch is connected to the atomizing nozzle and the controller of the air supply device, and is used to turn on or off the humidifying device according to the instruction of the controller.

[0079] Optionally, the water reservoir is arranged at the bottom of the air duct where the second air outlet is located, so as to facilitate replacement and cleaning by the user.

[0080] Optionally, the water reservoir is positioned below the dust filter at the second air outlet to recover water droplets condensed from the air mist passing through the dust filter. When air enters the second air outlet, the mist encounters the dust filter, condenses into water droplets that fall into the water reservoir, achieving the effects of cleaning, humidification, and recovery.

[0081] Optionally, the air supply device may further include an interactive device connected to the dust reduction control device for receiving user-set commands, wherein the user-set commands are used to turn the humidifier on or off and control the first and second air outlets accordingly. Specifically, the interactive device may be a touch screen or button provided on the air supply device, or a remote control.

[0082] The dust control scheme described above is described below with reference to a specific example. However, it should be noted that this specific example is only intended to better illustrate the present application and does not constitute an undue limitation on the present application. Explanations of terms that are identical or corresponding to those in the above examples will not be repeated in this example.

[0083] refer to Figure 3 Taking the air conditioner as an example, after the air conditioner is turned on and runs stably, the dust content detection device and humidity detection device at the upper air outlet start working, regularly detecting the dust content P and the current humidity coefficient Q in the air, and sending the detection information to the air conditioner control system.

[0084] The control system combines the preset dust content threshold N and the preset optimal humidity coefficient M, and conducts a comparative analysis with the current detection information. When P≥N or Q<M is satisfied, the humidifying device is controlled to start. After a period of time T (this time can be customized and adjusted), the dust content and humidity coefficient in the air are detected again. When it is detected that the dust content has dropped below the threshold N and the current humidity reaches the optimal humidity M, the humidifying device is turned off; when it is detected that the dust content has dropped below the threshold N but the current humidity does not reach the optimal humidity M, humidification continues, and detection and judgment are carried out again after a period of time T; when it is detected that the dust content is still at or above the threshold N, humidification continues, and detection and judgment are carried out again after a period of time T. In practical applications, the detection and judgment of the dust content and environmental humidity do not distinguish between the order and can also be executed simultaneously. In Figure 3 When the air conditioner starts to operate stably, it first detects the dust content. If the dust content is below the threshold N, it then detects the humidity coefficient. If the current humidity is less than the optimal humidity, the humidifying device is turned on. If the current humidity is greater than or equal to the optimal humidity, the humidity can continue to be detected, or it can return to S302 to detect the dust content.

[0085] Through such a cyclic process of upper-air outlet humidification and lower-air return filtration, the dust in the air can be effectively cleaned and the air can be purified. At the same time, through humidification, the problem of air dryness caused by the long-term operation of the air conditioner can be solved, the environmental humidity balance can be improved, and a more comfortable living environment can be provided for users.
