Description

Technical Field

[0001] This invention relates to the field of air conditioning humidification technology, specifically providing an air conditioner with humidification function and its control method. Background Technology

[0002] With the improvement of living standards and air conditioning technology, existing air conditioners can not only cool or heat indoor air, but also combine with the air conditioner by setting up a humidification module, so that the air conditioner can humidify the indoor air at the same time as cooling or heating.

[0003] Specifically, the existing humidification module installed on air conditioners is a wet curtain. This wet curtain is placed on the air inlet or outlet of the air conditioner to humidify the indoor air in conjunction with the air conditioner's blowing function. However, when an air conditioner using a wet curtain as a humidification module humidifies the room, it simply combines the air conditioner's blowing function with the wet curtain without setting precise control parameters to humidify the indoor air, resulting in unstable indoor humidity.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that when the existing method of setting up a wet curtain on an air conditioner to humidify the room, it simply combines the air blowing function of the air conditioner with the wet curtain without setting precise control parameters to humidify the indoor air, resulting in unstable indoor humidity.

[0008] The initial indoor air humidity and the fan speed of the air conditioner are obtained;

[0009] The target moisture content of the wet curtain medium is determined based on the initial air humidity, the target air humidity, and the fan speed.

[0010] The current moisture content of the evaporative cooling pad medium is adjusted to the target moisture content, so that the evaporative cooling pad assembly humidifies the indoor air at the target moisture content.

[0011] In the preferred embodiment of the control method for the air conditioner with humidification function described above, the step of determining the target moisture content of the wet curtain medium based on the initial air humidity, the target air humidity, and the fan speed includes:

[0012] When the target air humidity is greater than the initial air humidity, the current indoor air humidity is obtained;

[0013] When the current air humidity is less than the target air humidity, a preset first mapping table that stores the correspondence between the fan speed and the first moisture content of the wet curtain medium is invoked;

[0014] The target moisture content is determined based on the fan speed and the first mapping relationship, so that the wet curtain assembly can humidify the indoor air at the fastest humidification rate based on the fan speed.

[0015] In the preferred embodiment of the control method for the air conditioner with humidification function described above, the control method further includes the following steps:

[0016] After the current air humidity equals the target air humidity, the humidification time of the wet curtain assembly is obtained when the current indoor air humidity reaches the target air humidity from the initial air humidity.

[0017] Obtain the first indoor air temperature and the indoor space dimensions;

[0018] Calculate the humidity difference between the target air humidity and the initial air humidity;

[0019] The target moisture content is determined as the second moisture content based on the humidity difference, the humidification time, the first air temperature, the space size, and the fan speed, so that when the wet curtain assembly humidifies the indoor air with the second moisture content, the indoor air humidity can be maintained at the target air humidity.

[0020] In a preferred embodiment of the control method for the aforementioned air conditioner with humidification function, the step of determining the target moisture content as a second moisture content based on the humidity difference, the humidification time, the air temperature, the space dimensions, and the fan speed, so as to maintain the indoor air humidity at the target air humidity, includes:

[0021] Call the preset second mapping table that stores the corresponding relationships between the humidity difference, the humidification time, the first air temperature, the space size, the fan speed and the second moisture content;

[0022] The second moisture content is determined based on the humidity difference, the air temperature, the space dimensions, the fan speed, and the second mapping table.

[0023] In the preferred embodiment of the control method for the air conditioner with humidification function described above, the step of determining the target moisture content of the wet curtain medium based on the initial air humidity, the target air humidity, and the fan speed further includes:

[0024] When the target air humidity is less than or equal to the initial air humidity, the target moisture content is determined to be zero.

[0025] The control unit issues a reminder that the room needs to be dehumidified.

[0026] In a preferred embodiment of the control method for the aforementioned air conditioner with humidification function, the evaporative cooling pad assembly further includes a weight sensor disposed between the evaporative cooling pad medium and the evaporative cooling pad frame. The step of adjusting the current moisture content of the evaporative cooling pad medium to the target moisture content includes:

[0027] Obtain the initial weight of the evaporative cooling pad medium;

[0028] The first weight of the liquid water adhering to the wet curtain medium is determined based on the initial weight and the target moisture content;

[0029] Adjust the current weight of the liquid water on the wet curtain medium so that the current weight is equal to the first weight.

[0030] In a preferred embodiment of the control method for the aforementioned air conditioner with humidification function, the evaporative cooling pad assembly further includes a filter sponge and a water distribution pipe. The filter sponge is disposed on top of the evaporative cooling pad medium and is used to uniformly supply liquid water to the evaporative cooling pad medium. The water distribution pipe is uniformly distributed inside the filter sponge so that the water distribution pipe can uniformly increase or decrease the second weight of the liquid water in the filter sponge. The step of adjusting the current weight of the liquid water on the evaporative cooling pad medium so that the current weight is equal to the first weight includes:

[0031] When the current weight is greater than the first weight, the water distribution pipe is controlled to absorb liquid water from the filter sponge to reduce the rate at which the filter sponge replenishes water to the evaporative cooling pad medium, thereby reducing the current weight of liquid water in the evaporative cooling pad medium. When the weight of liquid water in the evaporative cooling pad medium reaches the first weight, the water supply rate of the water distribution pipe to the filter sponge is controlled to maintain the weight of liquid water in the evaporative cooling pad medium at the first weight; and / or

[0032] When the current weight is less than the first weight, the water distribution pipe is controlled to increase the rate at which liquid water is supplied to the filter sponge, thereby increasing the weight of liquid water in the evaporative cooling pad medium. When the weight of liquid water in the evaporative cooling pad medium reaches the first weight, the water supply rate of the water distribution pipe to the filter sponge is controlled so that the weight of liquid water in the evaporative cooling pad medium remains at the first weight; and / or

[0033] When the current weight is equal to the first weight, the water supply rate from the water distribution pipe to the filter sponge is controlled so that the weight of the liquid water in the wet curtain medium is maintained at the first weight.

[0034] In a preferred embodiment of the control method for the aforementioned air conditioner with humidification function, the step of controlling the water supply rate of the water distribution pipe to the filter sponge when the weight of the liquid water in the evaporative cooling pad reaches the first weight, so that the weight of the liquid water in the evaporative cooling pad remains at the first weight, includes:

[0035] Obtain the second air temperature inside the room;

[0036] The water supply rate is determined based on the second air temperature, the fan speed, and the target moisture content.

[0037] The water distribution pipeline is controlled to supply water to the filter sponge at the specified water supply rate.

[0038] In the preferred embodiment of the control method for the air conditioner with humidification function described above, the step of determining the water supply rate based on the second air temperature, the fan speed, and the target moisture content includes:

[0039] Call the preset third mapping table that stores the correspondence between the second air temperature, the fan speed, the target moisture content, and the water supply speed;

[0040] The water supply rate is determined based on the second air temperature, the fan speed, the target moisture content, and the third mapping table.

[0041] In a second aspect, the present invention also provides an air conditioner with a humidification function, the air conditioner including a controller configured to perform the control method described above.

[0042] By adopting the above technical solution, the present invention can adjust the moisture content of the wet curtain medium based on the target air humidity, the initial indoor air humidity and the fan speed, so that the air conditioner can humidify the indoor air more specifically, so that the indoor air humidity is more stable.

[0061] To address the issue that existing methods of using evaporative cooling pads on air conditioners to humidify indoor air simply combine the air conditioner's airflow function with the evaporative cooling pad without setting precise control parameters to humidify the indoor air, resulting in unstable indoor humidity.

Figure 12 This is a flowchart of another embodiment of the control method for an air conditioner with humidification function according to the present invention.

[0063] like Figure 1 As shown, see also Figure 2 and Figure 3 The present invention provides a control method for an air conditioner 100 with humidification function. The air conditioner 100 with humidification function includes an air conditioning body 1 and a wet curtain assembly 2. The wet curtain assembly 2 is located at the air inlet 11 of the air conditioning body 1. The wet curtain assembly 2 includes a wet curtain frame 21 and a wet curtain medium 22. The wet curtain medium 22 is located inside the wet curtain frame 21 and is configured to allow liquid water to be evenly distributed inside and on its surface.

[0064] It should be noted that, although the above combination Figure 1 The described evaporative cooling pad assembly 2 is installed at the air inlet 11 of the air conditioning unit 1, but this is not limiting. Those skilled in the art can also install the evaporative cooling pad assembly 2 at the air outlet of the air conditioning unit 1 as needed, but this is also not limiting. Those skilled in the art can also install the evaporative cooling pad assembly 2 at both the air inlet 11 of the air conditioning unit 1 and the air outlet of the unit as needed. Such adjustments do not deviate from the principle of the present invention and therefore will also fall within the protection scope of the present invention.

[0065] In this application, the upper end of the wet curtain medium 22 is connected to a connecting shaft (not shown) that extends in a horizontal direction. Both ends of the connecting shaft are connected to the wet curtain frame 21, so that the wet curtain medium 22 can be suspended inside the wet curtain frame 21.

[0066] In this application, the wet curtain assembly 2 also includes a gravity sensor (not shown), which is disposed between the connecting shaft and the wet curtain frame 21 to detect the weight change of the wet curtain medium 22, so that the weight sensor can detect the weight change of the liquid water on the wet curtain medium 22.

[0067] like Figure 1 As shown, see also Figure 3 In this application, the evaporative cooling pad assembly 2 further includes a filter sponge 26 and a water distribution pipe 23. The filter sponge 26 is disposed on top of the evaporative cooling pad medium 22 and is in contact with the evaporative cooling pad medium 22, so that the liquid water in the filter sponge 26 can enter the evaporative cooling pad medium 22 under the action of gravity and the surface tension of the liquid water itself. The water distribution pipe 23 is connected to the filter sponge 26 and is configured to uniformly increase or decrease the weight of the liquid water in the filter sponge 26. Specifically, the first end of the water distribution pipe 23 is provided with a first opening, which is connected to a water pump 24. The water pump 24 is connected to a water source or a water storage tank 25 through a pipe. The second end of the water distribution pipe 23 has multiple second openings, which are evenly distributed inside the filter sponge 26, so that the water distribution pipe 23 can uniformly increase or decrease the weight of the liquid water in the filter sponge 26 through the multiple openings under the action of the water pump 24.

[0068] It should be noted that, in other embodiments of the present invention, the filter sponge 26 is configured to be disposed on top of the wet curtain medium 22, and the sidewall of the filter sponge 26 abuts against the sidewall of the wet curtain medium 22, thereby increasing the contact area between the filter sponge 26 and the wet curtain medium 22. Moreover, since the filter sponge 26 and the sidewall of the wet curtain medium 22 can form a surface contact, the liquid water inside the filter sponge can enter the wet curtain medium 22 uniformly and quickly through the contact surface.

[0069] Furthermore, despite the above combination Figure 3 The described evaporative cooling pad assembly 2 includes a water storage tank 25, but this is not limiting. In specific implementations of the present invention, the evaporative cooling pad assembly 2 may not include the water storage tank 25. In this case, the evaporative cooling pad assembly 2 can be connected to an external water source pipe through the water distribution pipe 23 or connected to a water tank installed inside the air conditioner 100.

[0070] In this application, the air conditioner 100 also includes a speed sensor (not shown), which is located inside the air conditioner body 1 and is used to detect the fan speed inside the air conditioner body 1.

[0071] In this application, the air conditioner 100 also includes a temperature sensor (not shown), which is disposed on the air conditioner body 1 and is used to detect the indoor air temperature.

[0072] In this application, the air conditioner 100 also includes a humidity sensor (not shown), which is disposed on the air conditioner body 1 and is used to detect the indoor air humidity.

[0073] In this invention, the air conditioner 100 also includes a controller (not shown), which is connected to a fan, a water pump 24, a temperature sensor, a humidity sensor, and a weight sensor. In this way, the controller can humidify the indoor air based on the control commands input by the user and the current air humidity and air temperature. It should be noted that the controller can be a control chip that is already present in the air conditioner 100, or it can be a control module specifically used to execute the control method of this application, or it can be a functional unit of the control module.

[0074] Below, refer to Figures 4 to 12 This paper describes possible implementations of the control method for an air conditioner with humidification function according to the present invention.

[0075] like Figure 4 As shown, in one possible implementation, the control method of the air conditioner with humidification function of the present invention includes the following steps:

[0076] S101: Receives control commands, including the target air humidity;

[0077] S102: Obtain the initial indoor air humidity and the air conditioner fan speed;

[0078] S103: Determine the target moisture content of the wet curtain medium based on the initial air humidity, target air humidity, and fan speed;

[0079] S104: Adjust the current moisture content of the evaporative cooling pad medium to the target moisture content, so that the evaporative cooling pad assembly humidifies the indoor air at the target moisture content.

[0080] In S101, the control command can be input by the user through a control panel (not shown) set on the air conditioner body of the air conditioner, but this is not limiting. In specific implementation of the present invention, the control command can also be input through a remote control and / or a mobile terminal. Furthermore, the control command includes the target air humidity.

[0081] In S102, a humidity sensor installed on the air conditioner unit detects the initial indoor air humidity and transmits the initial air humidity information to the controller. A speed sensor detects the speed of the fan installed inside the air conditioner unit and transmits the fan speed information to the controller.

[0082] In S103, the air conditioner can determine the target moisture content of the wet curtain medium based on the initial air humidity, the target air humidity, and the fan speed. This allows the air conditioner to determine the target moisture content of the wet curtain medium based on the user's needs, the initial indoor air humidity, and the fan speed inside the air conditioner unit. This enables the air conditioner to humidify the indoor air more effectively, resulting in more stable indoor air humidity.

[0083] It should be noted that in the specific implementation of this invention, the user can simultaneously cool or heat the room using an air conditioner and humidify it. In this case, the indoor air temperature will gradually change towards the user's set target temperature during the air conditioner's operation. During this gradual change in indoor air temperature towards the user's set target temperature, the fan speed inside the air conditioner can be fixed. Therefore, when the fan speed remains constant, the target moisture content also remains constant. For example, if the fan inside the air conditioner is a fixed-frequency fan, the fan speed will remain constant when the air conditioner cools the indoor air. However, this is not limiting. In the specific implementation of this invention, the fan inside the air conditioner can also be a variable-frequency fan. In this case, if the user inputs a control command to keep the fan speed constant, the target moisture content can also remain constant. For example, when the indoor air temperature reaches the user's set target temperature, the fan speed inside the air conditioner can remain constant. Alternatively, before the user goes to sleep, the user can input a control command to keep the fan speed constant, in which case the fan speed will also remain constant. Conversely, in this embodiment of the invention, the fan speed inside the air conditioner unit can also be varied. In this case, the target moisture content will change according to the fan speed, as long as the moisture content of the wet curtain medium can be adjusted according to the fan speed.

[0084] In S104, after the target moisture content is determined, the controller adjusts the speed at which the water pump replenishes liquid water to the filter sponge through the water distribution pipeline, thereby adjusting the water supply speed from the filter sponge to the evaporative cooling pad. When the water supply speed is increased, the filter sponge can directly increase the moisture content of the evaporative cooling pad. When the water supply speed is decreased, due to the operation of the fan, the liquid water on the evaporative cooling pad will continuously be converted into gaseous water. In this way, after the water supply speed is reduced to a certain value, the moisture content of the evaporative cooling pad gradually decreases. The moisture content of the evaporative cooling pad is regulated through the above settings.

[0085] It should be noted that although the above method of adjusting the speed at which the water pump replenishes the filter sponge with liquid water is controlled to regulate the evaporative cooling pad medium, this is not a limitation. In other embodiments of the present invention, the lower end of the evaporative cooling pad medium can be immersed in a water box containing liquid water, so that the evaporative cooling pad medium absorbs the liquid water in the water box through the principle of capillary action. Based on this, when it is necessary to adjust the moisture content of the evaporative cooling pad medium, the moisture content of the evaporative cooling pad medium can be adjusted by adjusting the amount of liquid water in the water box.

[0086] like Figure 5 As shown, in one possible implementation, the control method for an air conditioner with humidification function according to the present invention further includes the following steps:

[0087] S201: When the target air humidity is greater than the initial air humidity, obtain the current indoor air humidity;

[0088] S202: When the current air humidity is less than the target air humidity, call the preset first mapping table that stores the correspondence between the fan speed and the first moisture content of the wet curtain medium;

[0089] S203: The target moisture content is determined as the first moisture content based on the fan speed and the first mapping relationship.

[0090] In S201, when the controller detects that the target air humidity is greater than the initial air humidity, the humidity sensor detects the current indoor air humidity.

[0091] In step S202, if the current air humidity is lower than the target air humidity, it indicates that the indoor air humidity needs to be increased. At this time, a pre-set mapping table stored inside the controller, which contains the correspondence between fan speed and the first moisture content of the evaporative cooling pad medium, is invoked. It should be noted that although the mapping table described above is pre-stored inside the controller, this is not a limitation. The controller can also be configured to match the corresponding first mapping table in a local database, cloud database, or network database based on the received control commands and clothing characteristics.

[0092] In S203, when the controller receives the fan speed, it can call a preset first mapping table stored inside the controller and compare the called first mapping table with the fan speed. This allows the controller to determine the target moisture content as a first moisture content based on the fan speed and the first mapping table. Furthermore, since the first moisture content is the moisture content that allows the liquid water on the evaporative cooling pad to vaporize most quickly at that fan speed, even when the current indoor air humidity has not reached the target humidity, the evaporative cooling pad assembly can humidify the indoor air at the fastest speed without adjusting the fan speed inside the air conditioner unit. This increases the rate of increase in indoor air humidity and improves the user experience.

[0093] like Figure 6 As shown, in one possible implementation, the control method for an air conditioner with humidification function according to the present invention further includes the following steps:

[0094] S301: After the current air humidity equals the target air humidity, obtain the humidification time of the wet curtain assembly when the current indoor air humidity reaches the target air humidity from the initial air humidity.

[0095] S302: Obtain the initial indoor air temperature and indoor space dimensions;

[0096] S303: Calculate the humidity difference between the target air humidity and the initial air humidity;

[0097] S304: The target moisture content is determined as the second moisture content based on the humidity difference, humidification time, first air temperature, space size, and fan speed.

[0098] In S301, after the humidity sensor detects that the current indoor air humidity has reached the target air humidity, the controller obtains and records the humidification time taken by the wet curtain assembly to humidify the indoor air from the initial air humidity to the target air humidity.

[0099] In S302, the initial indoor air temperature is obtained through a temperature sensor. The space dimensions can be input by the user via a control button on the air conditioner; alternatively, they can be input via a mobile terminal. It should be noted that the space dimensions can also be measured using at least one of the following sensors with distance measurement capabilities: laser rangefinders, ultrasonic rangefinders, and structured light sensors deployed indoors. Specific measurement processes and details are not elaborated here; the key is that the sensors can detect the outline information of the indoor space, including length, width, height, wall positions, and furniture layout.

[0100] In S303, the controller calculates the humidity difference between the target air humidity and the initial air humidity, and records the humidity difference.

[0101] In S304, the target moisture content is determined as the second moisture content based on the humidity difference, humidification time, first air temperature, space size, and fan speed, so that when the air conditioner humidifies the indoor air with the second moisture content through the wet curtain assembly, the indoor air humidity can be maintained at the target air humidity, thus ensuring the stability of the indoor air humidity.

[0102] It should be noted that the aforementioned fan speed is obtained by a speed sensor. Specifically, the fan can be a fixed-frequency fan or a variable-frequency fan. When the fan is a fixed-frequency fan, the speed sensor only needs to detect the fan speed once. When the fan is a variable-frequency fan, the speed can be obtained in real time by the speed sensor. In this case, the fan speed can be fixed or variable. For example, if the indoor air temperature has reached the target air temperature, the air conditioner only needs to maintain the indoor air temperature at the target air temperature. In this case, the fan speed can remain constant. However, this is not limiting. In the specific implementation of this invention, even after the indoor air temperature reaches the target air temperature, the fan speed can still change. In this case, the second moisture content can change according to the change in fan speed, as long as the indoor air humidity is maintained at the target air humidity.

[0103] Furthermore, in a specific implementation of this invention, a preset humidity difference threshold can be set. By setting the humidity difference threshold, when the wet curtain medium is used for humidification indoors at a second moisture content, the difference between the current air humidity and the target air humidity can be controlled to be less than the preset humidity difference threshold. Or, if the difference between the current air humidity and the target air humidity is greater than the preset humidity difference threshold when the wet curtain medium is used for humidification indoors at a second moisture content, the second moisture content needs to be adjusted according to the difference between the current air humidity and the target air humidity. For example, if the current air humidity is greater than the target air humidity, the controller adjusts the power of the water pump to gradually reduce the value of the second moisture content. Conversely, if the current air humidity is less than the target air humidity, the controller adjusts the power of the water pump to gradually increase the value of the second moisture content. This configuration ensures that the difference between the current indoor air humidity and the target air humidity is less than a preset humidity difference threshold. The controller then obtains a newly determined second moisture content that ensures the difference between the current and target air humidity is less than the preset threshold. The second moisture content, previously determined based on the humidity difference, humidification time, first air temperature, room dimensions, and fan speed, is adjusted to this newly determined second moisture content. This ensures that, under the same indoor conditions, the difference between the current and target air humidity is less than the preset threshold based on the newly determined second moisture content. This configuration allows the air conditioner of this invention to humidify the room more intelligently.

[0104] Furthermore, although the second moisture content described above is determined based on the humidity difference, humidification time, first air temperature, space size, fan speed, and second moisture content, this is not limiting. In specific implementations of the present invention, the second moisture content can also be determined based on the current indoor air pressure, humidity difference, humidification time, first air temperature, space size, and fan speed. However, this is also not limiting. In other embodiments of the present invention, the second mapping table can also be determined based on other parameters affecting the vaporization rate of liquid water, such as the current indoor air pressure, humidity difference, humidification time, first air temperature, space size, fan speed, and second moisture content.

[0105] like Figure 7 As shown, in one possible implementation, the control method for an air conditioner with humidification function according to the present invention further includes the following steps:

[0106] S401: Call the preset second mapping table that stores the corresponding relationships between humidity difference, humidification time, first air temperature, space size, fan speed and second moisture content;

[0107] S402: Determine the second moisture content based on the humidity difference, air temperature, space dimensions, fan speed, and the second mapping table.

[0108] In S401, the controller stores a second mapping table containing preset correspondences between humidity difference, humidification time, first air temperature, space dimensions, fan speed, and second moisture content. It should be noted that the correspondences between humidity difference, humidification time, first air temperature, space dimensions, fan speed, and second moisture content in the second mapping table can be obtained by the designer through experiments.

[0109] In S402, the air conditioner can determine the second moisture content of the wet curtain medium based on different indoor temperatures, space dimensions, humidification time, fan speed, and a second mapping table, so as to maintain the indoor air humidity at the target air humidity. For example, when a user installs the air conditioner of this invention indoors and uses it to adjust the temperature and humidity, if the parameters of the indoor space size, the first indoor air temperature, the fan speed, and the humidity difference remain unchanged, and the humidification time required for the air conditioner to reach the target air humidity from the initial air humidity through the wet curtain assembly changes, it indicates that other variables have appeared indoors. These other variables affect the rate at which the indoor humidity rises, thus leading to an extension of the humidification time. In this case, to eliminate the influence of other variables on the rise of indoor air humidity, it is necessary to correspondingly increase the second moisture content of the wet curtain medium. Moreover, since the rate at which the indoor air humidity rises is directly linked to the humidification time, the value of the second moisture content should be changed accordingly while keeping the parameters of the space size, the first indoor air temperature, the fan speed, and the humidity difference unchanged, so that the indoor air humidity can be maintained at the target air humidity by adjusting the second moisture content.

[0110] Those skilled in the art will understand that, since the second mapping relationship table of the present invention is derived by the designers based on experimental training, the parameters of humidity difference, humidification time, first air temperature, space size, fan speed, and second moisture content in the second mapping relationship table have a corresponding relationship. Therefore, in other embodiments of the present invention, when at least one of the parameters of humidity difference, first air temperature, space size, and fan speed changes, the present invention can also determine the second moisture content based on the obtained humidity difference, humidification time, first air temperature, space size, and fan speed, so that after the indoor air humidity reaches the target air humidity, the second moisture content of the wet curtain medium can be adjusted to maintain the indoor air humidity at the target air humidity, thereby ensuring the stability of the indoor air humidity. It should be noted that although the second moisture content described above is confirmed based on the correspondence between the parameters of humidity difference, humidification time, first air temperature, space size, fan speed and second moisture content stored in the second mapping table, this is not limiting. In specific implementations of the present invention, the second mapping table may also store the correspondence between the parameters of current indoor air pressure, humidity difference, humidification time, first air temperature, space size, fan speed and second moisture content, but this is also not limiting. In other embodiments of the present invention, the second mapping table may also store other parameters that affect the vaporization rate of liquid water, such as current indoor air pressure, humidity difference, humidification time, first air temperature, space size, fan speed and second moisture content.

[0111] like Figure 8 As shown, in one possible implementation, the control method for an air conditioner with humidification function according to the present invention further includes the following steps:

[0112] S501: When the target air humidity is less than or equal to the initial air humidity, the target moisture content is determined to be zero;

[0113] S502: The control prompt unit issues a reminder that indoor dehumidification is required.

[0114] In step S501, when the target air humidity is less than or equal to the initial air humidity, it indicates that the current indoor air humidity is greater than the target air humidity input by the user. In this case, the air conditioner does not need to humidify the room. In this situation, the target moisture content of the evaporative cooling pad is set to zero. This allows the invention to adjust the moisture content of the evaporative cooling pad to zero based on the target moisture content, thus preventing further increases in indoor air humidity caused by humidifying the room through the evaporative cooling pad during air conditioner operation. Specifically, when the target air humidity is less than or equal to the initial air humidity, the controller controls a water pump to draw water from the filter sponge through the water distribution pipe, rapidly reducing the liquid water content in the filter sponge. This quickly reduces the water supply rate from the filter sponge to the evaporative cooling pad. Under these conditions, since the air conditioner's fan is continuously running, the liquid water content on the evaporative cooling pad gradually decreases to zero, thereby adjusting the current moisture content of the evaporative cooling pad to zero.

[0115] In S502, after detecting that the initial indoor air humidity is greater than the target air humidity, the controller controls the prompting unit installed on the air conditioner to remind the user that dehumidification is needed, so that the user can determine whether dehumidification is required based on the reminder. It should be noted that this prompting unit can be an audible prompter installed on the air conditioner, such as a buzzer, alarm, voice announcer, music player, etc., so that the prompter can remind the user by emitting a specific sound. However, this is not a limitation; the prompting unit can also be a visual prompter, such as an indicator light, LED display, LCD screen, projector, etc., so that the prompter can convey prompts by displaying text, graphics, animation, or video information.

[0116] like Figure 9 As shown, in one possible implementation, the control method for an air conditioner with humidification function according to the present invention further includes the following steps:

[0117] S601: Obtain the initial weight of the evaporative cooling pad medium;

[0118] S602: Determine the first weight of liquid water adhering to the wet curtain medium based on the initial weight and target moisture content;

[0119] S603: Adjust the current weight of the liquid water on the wet curtain medium so that the current weight is equal to the first weight.

[0120] In S601, the initial weight of the wet curtain medium without liquid water is detected by a weight sensor, and the weight sensor sends the initial weight information to the controller, which then obtains the initial weight of the wet curtain medium.

[0121] In S602, the first weight of liquid water adhering to the wet curtain medium is determined based on the initial weight and target moisture content obtained by the controller, wherein the target moisture content = first weight / initial weight.

[0122] In S603, the current weight of the liquid water on the evaporative cooling pad is adjusted so that the current weight of the liquid water on the evaporative cooling pad is equal to the first weight. This allows the air conditioner to adjust the moisture content of the evaporative cooling pad according to changes in indoor air humidity when humidifying the room through the evaporative cooling pad assembly. This ensures that the indoor air humidity changes according to preset conditions. For example, when the current indoor air humidity is less than the target air humidity, adjusting the moisture content of the evaporative cooling pad allows the air conditioner operating at the current fan speed to achieve maximum humidification efficiency when humidifying the indoor air. Alternatively, when the current indoor air humidity is equal to the target air humidity, adjusting the moisture content of the evaporative cooling pad allows the air conditioner operating at the current fan speed to maintain the indoor air humidity at the target air humidity when humidifying the indoor air. Alternatively, when the current indoor air humidity is higher than the target air humidity, the system can remind the user through a prompt unit on the air conditioner that the indoor air humidity is higher than the target air humidity, allowing the user to decide whether to turn on the dehumidifier to dehumidify the room.

[0123] like Figure 10 As shown, in one possible implementation, the control method for an air conditioner with humidification function according to the present invention further includes the following steps:

[0124] S701: Compare the current weight of liquid water in the wet curtain medium with the first weight;

[0125] S702: When the current weight is greater than the first weight, control the water distribution pipe to absorb the liquid water in the filter sponge to reduce the water replenishment speed of the filter sponge to the wet curtain medium, thereby reducing the current weight of the liquid water in the wet curtain medium. When the weight of the liquid water in the wet curtain medium reaches the first weight, control the water supply speed of the water distribution pipe to the filter sponge so that the weight of the liquid water in the wet curtain medium is kept at the first weight.

[0126] S703: When the current weight is less than the first weight, control the water distribution pipe to increase the speed of supplying liquid water to the filter sponge, thereby increasing the first weight of liquid water in the wet curtain medium. When the weight of liquid water in the wet curtain medium reaches the first weight, control the water supply speed of the water distribution pipe to the filter sponge so that the weight of liquid water in the wet curtain medium is kept at the first weight.

[0127] S704: When the current weight equals the first weight, control the water supply speed of the water distribution pipe to the filter sponge so that the weight of the liquid water in the wet curtain medium is kept at the first weight.

[0128] In S702, when the current weight of the liquid water in the evaporative cooling pad medium is greater than the first weight, the controller controls the water pump to absorb the liquid water from the filter sponge through the water distribution pipe. This reduces the rate at which the filter sponge replenishes water to the evaporative cooling pad medium. At the same time, due to the operation of the air conditioner fan, the liquid water in the evaporative cooling pad medium is vaporized, which reduces the current weight of the liquid water in the evaporative cooling pad medium accordingly. When the weight of the liquid water in the evaporative cooling pad medium reaches the first weight, the water supply rate of the water distribution pipe to the filter sponge is controlled so that the weight of the liquid water in the evaporative cooling pad medium remains at the first weight.

[0129] It should be noted that, in the specific implementation of this invention, the first end of the water distribution pipe is connected to the water pump, the second end of the water distribution pipe is embedded in the filter sponge, and the second end of the water distribution pipe is connected to multiple pipes of different lengths so that when the water pump draws water from the filter sponge through the water distribution pipe, it can quickly and evenly draw water from the filter sponge, thereby quickly reducing the water supply speed from the filter sponge to the wet curtain medium.

[0130] In S702, when the current weight of the liquid water in the evaporative cooling pad medium is less than a first weight, the controller controls the water pump to increase the speed at which liquid water is supplied to the filter sponge through the water distribution pipe, so that the current weight of the liquid water in the filter sponge can be increased. This increases the water replenishment speed of the filter sponge to the evaporative cooling pad medium, which in turn increases the current weight of the liquid water in the evaporative cooling pad medium. When the weight of the liquid water in the evaporative cooling pad medium reaches the first weight, the water supply speed of the water distribution pipe to the filter sponge is controlled so that the weight of the liquid water in the evaporative cooling pad medium is maintained at the first weight.

[0131] It should be noted that, in the specific implementation of this invention, since the second end of the water distribution pipe is embedded in the filter sponge, and the second end of the water distribution pipe is connected to multiple pipes of different lengths, when the water pump supplies water to the filter sponge through the water distribution pipe, the weight of the liquid water in the filter sponge can be increased quickly and evenly, thus rapidly increasing the water supply speed of the filter sponge to the wet curtain medium.

[0132] In S703, when the current weight of the liquid water in the wet curtain medium is equal to the first weight, the controller controls the water pump to increase the speed of supplying liquid water to the filter sponge through the water distribution pipeline, so that the weight of the liquid water in the wet curtain medium is maintained at the first weight.

[0133] like Figure 11 As shown, in one possible implementation, the control method for an air conditioner with humidification function according to the present invention further includes the following steps:

[0134] S801: Obtain the second indoor air temperature;

[0135] S802: Determine the water supply rate based on the second air temperature and the fan speed;

[0136] S803: Controls the water distribution pipeline to supply water to the filter sponge at the water supply rate.

[0137] In S801, when the current weight of the liquid water in the wet curtain medium is equal to the first weight mentioned above, the second air temperature in the room is obtained by the temperature sensor.

[0138] In S802, the water supply speed of the water distribution pipe to the filter sponge is determined based on the second temperature and the fan speed. The second temperature and the fan speed are parameters that directly affect the vaporization rate of liquid water on the wet curtain assembly. Therefore, in a specific implementation of the present invention, the water supply speed can be determined based on the second temperature and the fan speed. However, this is not a limitation. In a specific implementation of the present invention, the water supply speed of the water distribution pipe to the filter sponge can also be determined based on the current indoor air pressure, the current air humidity, the second temperature, and the fan speed. The current air pressure can be detected by a barometer installed on the air conditioner. However, this is not a limitation either. The current air pressure can also be detected by the user's mobile terminal.

[0139] It should be noted that although the water supply speed described above is determined by the second temperature, fan speed, current air pressure, and current air humidity, this is not limiting. In specific implementations of this invention, the water supply speed can also be determined by other parameters that affect the vaporization rate of liquid water on the wet curtain medium. As long as the water distribution pipe can indirectly maintain the liquid water in the wet curtain medium at the first weight when supplying liquid water to the filter sponge at this water supply speed, such adjustment does not deviate from the principle of this invention and therefore will also fall within the protection scope of this invention.

[0140] like Figure 12 As shown, in one possible implementation, the control method for an air conditioner with humidification function according to the present invention further includes the following steps:

[0141] S901: Call the preset third mapping table that stores the correspondence between the second air temperature, fan speed and water supply speed;

[0142] S902: Determine the water supply rate based on the second air temperature, fan speed, and the third mapping table.

[0143] In S901, the controller stores a third mapping table showing the preset correspondence between the second air temperature, fan speed, and water supply speed. It should be noted that the correspondence between the second air temperature, fan speed, and water supply speed in the third mapping table can be obtained by the designer through experiments.

[0144] It should be noted that although the third mapping table described above stores the correspondence between the second air temperature, the fan speed and the water supply speed, this is not limiting. Those skilled in the art can also make the third mapping table store the correspondence between the current air pressure, the current air humidity, the second temperature and the fan speed as needed. Such adjustments do not deviate from the principle of the present invention and therefore will also fall within the protection scope of the present invention.

[0145] In S902, the water supply speed is determined based on the second air temperature, the fan speed, and the third mapping table, so that the weight of the liquid water in the wet curtain medium is maintained at the first weight.

Such modified technical solutions do not change the basic concept of this application and therefore fall within the protection scope of this application.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
