Description

Technical Field

[0001] This invention belongs to the field of air conditioner technology, specifically relating to a humidification control method, device, air conditioner and storage medium for an air conditioner, and particularly to a smart and fast humidification control method, device, air conditioner and storage medium for an air conditioner. Background Technology

[0002] As living standards continue to improve, people have higher and higher requirements for the comfort of indoor environments; air conditioners, as smart home appliances that can regulate indoor air temperature and humidity, are now widely used.

[0003] When summer nights are hot or winter nights are cold, users need to run the air conditioner all night to ensure a comfortable indoor temperature. However, prolonged air conditioning use, whether cooling or heating, leads to a drop in indoor humidity, causing users to experience discomfort such as dry mouth and throat the next day. Furthermore, in the dry winter climate, even if the ambient temperature reaches a comfortable level, the humidity may not be high enough for human comfort, resulting in overall less comfortable air conditioning use. Therefore, it is necessary to intelligently adjust the room's humidity based on the indoor temperature and humidity levels.

[0004] In the current technology of air conditioner humidification mode, on the one hand, users often do not set the humidity value in advance, and only choose to turn on the humidification mode when the humidity has already caused discomfort to the human body; on the other hand, the humidification mode of the air conditioner generally only starts working after the user selects to turn it on, and at this time the user often needs humidification urgently, but the mist output speed of the humidification device is slow at the beginning, thus affecting the actual user experience.

[0005] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

When the air conditioner enters humidification mode, it is determined that the user is already feeling uncomfortable and needs humidification.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0045] In existing solutions, users often don't pre-set humidity levels when using air conditioners; they only activate the humidification mode when the humidity becomes uncomfortable. Furthermore, the humidification mode typically only starts working after the user selects it, which is often when humidification is urgently needed, but the initial mist output is slow, impacting the user experience. To address this, the present invention provides a humidification control method for air conditioners to improve the overall comfort of the human environment. Specifically, by incorporating a steam generator and a steam storage device into the humidification unit of the air conditioner, the steam generator activates when it detects insufficient indoor humidity or receives a user command. The generated steam does not directly enter the room through the air conditioner but first enters the steam storage device. Only when the steam density in the storage device reaches a preset value is the storage device activated, allowing steam to enter the room. This allows the indoor humidity to rise rapidly under the influence of a large amount of steam, avoiding the slow mist output problem and significantly improving the user experience.

[0046] According to embodiments of the present invention, a humidification control method for an air conditioner is provided, such as... Figure 1 The diagram shows a flow chart of an embodiment of the method of the present invention. The air conditioner includes a humidification device, which includes: a steam generator 3 for generating steam; and a steam storage device 4, the steam storage device 4 having its air inlet side connected to the steam output side of the steam generator 3, for receiving and storing the steam generated and output by the steam generator 3.

[0047] It is worth noting that the steam generating device mentioned above can be any device that can convert water into water vapor, including ultrasonic atomizing humidifiers, evaporative humidifiers, etc.

[0048] like Figure 1 As shown, the humidification control method of the air conditioner includes steps S110 to S140.

[0049] Step S110: Confirm whether the current ambient humidity is lower than the first preset humidity;

[0050] Step S120: Confirm whether a command to enter humidification mode has been received;

[0051] Step S130: Confirm whether the steam density in the steam storage device is greater than the preset density value;

[0052] Step S140: If it is confirmed that the current ambient humidity is lower than the first preset humidity, the instruction to enter the humidification mode is received, and the steam density in the steam storage device is greater than the preset density value, then the steam storage device is turned on to deliver the steam stored in the steam storage device to the room.

[0053] In step S110, the first preset humidity is generally a preset value for the air conditioner. Since different users have different requirements for suitable humidity levels, this first preset humidity value is generally a suitable humidity level. At this humidity level, most users will not feel uncomfortable. Simultaneously, the air conditioner needs to monitor the current ambient humidity in real time to compare the current ambient humidity with the first preset humidity. When the current ambient humidity is lower than the first preset humidity, the current ambient humidity is not particularly high, meaning some users may feel the humidity is insufficient and may need to activate the humidification mode of the air conditioner to humidify the indoor environment. When the current ambient humidity is higher than the first preset humidity, it is assumed that no user will feel insufficient humidity. In this case, the air conditioner defaults to turning off the humidification device to avoid excessive energy waste.

[0054] Simultaneously, step S120: confirm whether a command to enter humidification mode has been received; this command can be a direct command from the user to enter humidification mode, i.e., the user feels uncomfortable when the humidity is insufficient and thus sends a command to enter humidification mode; in addition, to avoid the user not sending a command to enter humidification mode in time when the humidity is too low due to rest or other states, the controller can also give a command to enter humidification mode by further judging the current ambient humidity to ensure the user's comfort experience.

[0055] Meanwhile, in different implementations, the steam stored in the steam storage device in step S140 can be steam generated by controlling the operation of the steam generator at any time after the air conditioner starts running, or it can be humid steam that has been stored in advance before the air conditioner starts running. For example, if the steam generated by the air conditioner after the previous humidification mode is not discharged in time and is directly stored in the steam storage device, then when the humidification mode command is received this time, and the current ambient humidity is lower than the first preset humidity and the steam density in the steam storage device is greater than the preset density value, since the steam storage device already contains stored steam, it is not necessary to turn on the steam generator again. Only the steam storage device needs to be turned on to deliver steam into the room and increase the indoor ambient humidity.

[0056] The above solution involves installing a steam generator for producing humidified steam and a steam storage device for storing steam within the humidification unit of the air conditioner. The steam storage device is located at the steam outlet of the steam generator, and its inlet is connected to the outlet of the steam generator, allowing the steam generated by the steam generator to enter the steam storage device through a pipeline and be stored in advance. When the current ambient humidity is confirmed to be lower than a first preset humidity, the air conditioner enters humidification mode, and the current steam density in the steam storage device is greater than a preset density value, it can be determined that the user is feeling unwell and has issued a humidification command. Therefore, humidification is necessary to adjust the indoor humidity. Furthermore, the fact that the current steam density in the steam storage device is greater than the preset density value ensures that the humidification unit can quickly and abundantly release steam to increase indoor humidity. Therefore, when all the above conditions are met, the steam storage device is turned on, and the humidification device of the air conditioner begins to produce mist, delivering a large amount of pre-generated and stored steam to the room, thereby rapidly increasing the indoor humidity in a short period of time, thus achieving the technical effect of quickly improving the indoor environmental humidity and user comfort.

[0057] In some implementations, such as Figure 2 As shown, in conjunction with the current operating mode of the air conditioner, particularly the cooling mode or heating mode, the humidification control method of the air conditioner includes steps S210 and S220.

[0058] Before confirming that the current ambient humidity is lower than the first preset humidity, the method further includes:

[0059] Step S210: Determine the current operating mode of the air conditioner; confirm that the operating mode is either cooling mode or heating mode;

[0060] And, after confirming that the current ambient humidity is lower than the first preset humidity, and before confirming whether an instruction to enter humidification mode has been received, the method further includes;

[0061] Step S220: If it is confirmed that the current ambient humidity is lower than the first preset humidity, then: control the steam generator to turn on, so that the steam generator can generate steam, so that the steam can be generated in advance and stored in the steam storage device; then, perform an operation to confirm whether the steam density in the steam storage device is greater than the preset density value.

[0062] If it is confirmed that the steam density in the steam storage device is greater than the preset density value, then an operation is performed to confirm whether a command to enter the humidification mode has been received.

[0063] In either cooling or heating mode, prolonged operation of an air conditioner inevitably leads to a decrease in indoor humidity. Users are highly likely to activate the humidification mode due to this drop. Therefore, to ensure the air conditioner can deliver a large amount of steam promptly when humidification is activated, a steam generator is activated when the current ambient humidity is confirmed to be below a first preset humidity level. This generates steam and stores it in a steam storage device before the humidification mode is activated. By generating and storing steam in advance, when a humidification signal is received, the steam storage device will already contain a sufficient density of steam, allowing a large amount of steam to quickly enter the room and rapidly increase indoor humidity, thus significantly improving user comfort.

[0064] In some implementations, such as Figure 2 As shown, in either cooling or heating mode, the humidification device further includes a water tank 2, which is connected to the water inlet side of the steam generator 3, and a heat exchange device is installed inside the water tank 2; the control method further includes step S230.

[0065] Before the steam generator is turned on...

[0066] Step S230: Control the heat exchange device in the water tank to start, so that the water temperature in the water tank decreases or increases.

[0067] The water tank in the humidifier is used to store water. The water in the tank flows through the pipe from the outlet of the tank to the steam generator, where it is agitated or evaporated to become steam used to humidify the indoor environment. Therefore, by adjusting the water temperature in the tank, the temperature of the steam output by the humidifier can be kept consistent with the current ambient temperature, thereby achieving a temperature and humidity balance in the indoor environment and allowing the indoor temperature and humidity to quickly reach a comfortable state for the human body.

[0068] The heat exchange device in the humidification device can be one or both of a refrigeration device and a heating device, or a semiconductor heat exchanger can be used, so that the same heat exchanger can both cool and heat.

[0069] Specifically, when the air conditioner is in cooling mode, the current indoor environment requires low-temperature steam. The cooling unit in the water tank is activated, lowering the water temperature. The resulting humidifier then produces low-temperature steam which is delivered to the room. Conversely, when the air conditioner is in heating mode, the current indoor environment requires high-temperature steam. The heating unit in the water tank is activated, raising the water temperature. The humidifier then produces high-temperature steam which is delivered to the room. Thus, when the air conditioner is in either cooling or heating mode, the simultaneous activation of humidifiers achieves a balanced regulation of temperature and humidity, ensuring optimal temperature and humidity levels for the user, regardless of whether the air conditioner is cooling or heating.

[0070] In some implementations, such as Figure 3 As shown, in conjunction with the current operating mode of the air conditioner, especially in the air supply mode, the humidification control method of the air conditioner includes: steps S310 and S320.

[0071] Before confirming that the current ambient humidity is lower than the first preset humidity,

[0072] Step S310: Determine the current operating mode of the air conditioner; confirm that the operating mode is the air supply mode;

[0073] And, after confirming whether an instruction to enter humidification mode has been received, and before confirming whether the steam density in the steam storage device is greater than a preset density value,

[0074] Step S320: If it is confirmed that the current ambient humidity is lower than the first preset humidity and the instruction to enter the humidification mode is received, then: control the steam generator to turn on, so that the steam generator can generate steam, so that the steam can be generated in advance and stored in the steam storage device; then, perform the operation of confirming whether the steam density in the steam storage device is greater than the preset density value.

[0075] When the air conditioner is in fan mode, it cannot predict the possibility of insufficient humidity in the indoor environment as it can in cooling and heating modes. Therefore, to avoid wasting energy by turning on the steam generator prematurely, the air conditioner only considers the indoor environment to need humidification when it confirms that it has entered humidification mode. As a result, it controls the steam generator to turn on, generates steam, and stores the generated steam in the steam storage device. This can minimize unnecessary energy waste and consumption, and save energy.

[0076] In some implementations, such as Figure 4 As shown, the humidification control method of the air conditioner includes steps S410 and S420.

[0077] The step of confirming that the steam density in the steam storage device is greater than a preset density value includes:

[0078] Step S410: Determine the relationship between the steam density in the steam storage device and the preset density value;

[0079] When the steam density in the steam storage device is less than the preset density value;

[0080] Step S420: Control the steam generator to start until the steam density in the steam storage device is greater than the preset density value.

[0081] Most current air conditioner humidifiers automatically activate when the air conditioner receives a humidification command, releasing the generated steam into the room. However, at this point, the humidifier has just started, producing very little steam, which is barely perceptible to the user. This results in low overall humidification efficiency and no noticeable feedback from the user. Therefore, to ensure humidification efficiency, this invention ensures that the steam density in the steam storage device is greater than a preset value before the steam is released into the room. Specifically, in the case of a fan-operated humidifier that only starts operating and generating steam upon receiving a humidification command, the steam generator is activated, but the steam storage device remains closed. The steam generated by the generator is continuously stored in the storage device until the steam density exceeds the preset value, at which point the storage device is activated, allowing steam to enter the room. Because the volume of the steam storage device is significantly smaller than the volume of the room, steam can fill the steam storage device in a short time. When the steam storage device is activated, a large amount of steam enters the room at the same time. The humidification effect on the local area of ​​the room is more significant than that of a small amount of humid steam delivered over a long period of time. This achieves a rapid increase in indoor humidity and improves the user's comfort experience.

[0082] In some implementations, such as Figure 5 As shown, the humidification control method of the air conditioner includes steps S510 and S520.

[0083] The control of the steam storage device to open includes:

[0084] Step S510: Control the mist output speed of the steam storage device to be high when it is turned on;

[0085] and,

[0086] Step S520: Control the amount of mist output when the steam storage device is turned on to be large.

[0087] Therefore, when a humidification mode command is received and the humidification mode is activated, the wet steam in the steam storage device can be delivered to the room at the fastest speed, thereby rapidly improving the indoor humidity environment and enhancing the user's comfort experience.

[0088] In some implementations, such as Figure 6 As shown, the humidification control method of the air conditioner includes steps S610 and S620.

[0089] After the control unit for the steam storage device is turned on.

[0090] Step S610: Determine the ratio of the current ambient humidity to the second preset humidity.

[0091] Step S620: Adjust the humidification rate of the steam generator, the mist output rate of the steam storage device, and the mist output of the steam storage device according to the ratio.

[0092] The second preset humidity can be a humidity value set by the user. To avoid some users being unfamiliar with the use of the humidifier, the second preset humidity can also be a humidity value automatically set by the humidifier based on the local environment and the human comfort range.

[0093] In order to more intelligently adjust the humidity level of the current indoor environment and maintain it within the comfortable range for the human body, so as not to cause discomfort due to excessive humidity, the second preset humidity value can be either lower or higher than the first preset humidity value. In short, it is a humidity value that will make the human body feel comfortable, and the air conditioner will eventually reach this humidity value.

[0094] In some embodiments, adjusting the humidification rate of the steam generator, the mist output rate of the steam storage device, and the mist output of the steam storage device according to the ratio includes the following three adjustment modes:

[0095] The first adjustment mode: when the ratio is less than the first threshold, the humidification speed of the steam generator is controlled to be high speed, the mist output speed of the steam storage device is high speed, and the mist output of the steam storage device is large.

[0096] When the ratio is less than the first threshold, it is generally considered that the humidity of the indoor environment is far from the suitable humidity. At this time, it is necessary to quickly increase the indoor humidity by rapidly increasing a large amount of humidification, thereby improving the user's comfort. Therefore, at this time, the humidification speed of the steam generator is high speed, the mist output speed of the steam storage device is high speed, and the mist output of the steam storage device is large.

[0097] The second adjustment mode: when the ratio is greater than or equal to the first threshold and less than the second threshold, the humidification speed of the steam generator is controlled to be medium speed, the mist output speed of the steam storage device is controlled to be medium speed, and the mist output of the steam storage device is controlled to be medium.

[0098] When the ratio is between the first threshold and the second threshold, it is considered that the humidity of the indoor environment is about half away from the suitable humidity. At this time, it is not necessary to humidify rapidly and in large quantities as in the above situation. If humidification is carried out rapidly and in large quantities at this time, it is easy to cause excessive indoor humidity due to poor control, which will affect the user experience. Therefore, the humidification speed will be slowed down. At this time, the humidification speed of the steam generator is medium speed, the mist output speed of the steam storage device is medium speed, and the mist output of the steam storage device is medium.

[0099] The third adjustment mode: When the ratio is greater than or equal to the second threshold, the humidification speed of the steam generator is controlled to be low, the mist output speed of the steam storage device is controlled to be low, and the mist output of the steam storage device is controlled to be small.

[0100] When the ratio is greater than the second threshold, the humidity of the indoor environment is very close to the suitable humidity. At this time, only a small amount of humidification is needed to achieve the appropriate humidity value. Therefore, the humidification speed will be further slowed down. That is, the humidification speed of the steam generator is low, the mist output speed of the steam storage device is low, and the mist output of the steam storage device is small.

[0101] Therefore, in the early stage of humidification, when the ratio between the current ambient humidity and the second preset humidity is low, humidification is accelerated to provide a large amount of humidified steam, so that the room humidity can be increased quickly. In the later stage of humidification, when the ambient humidity is close to the second preset humidity, humidification is slowed down to reduce the output of humidified steam, prevent over-adjustment, and avoid excessive humidity affecting comfort. This plays a buffering role, thereby achieving intelligent regulation of indoor ambient humidity.

[0102] Specifically, the first threshold can be 0.8, and the second threshold is 0.9. The mist output speed of the steam storage device is achieved by installing a motor in the steam storage device and adjusting the motor speed. The mist output of the steam storage device is achieved by adjusting the size of the mist outlet of the steam storage device.

[0103] When the ratio of the current ambient humidity to the second preset humidity is less than 0.8, the humidification rate of the steam generator is high, the motor speed in the steam storage device is high, and the mist outlet size is large. When the ratio of the current ambient humidity to the second preset humidity is greater than or equal to 0.8 and less than 0.9, the humidification rate of the steam generator is medium, the motor speed in the steam storage device is medium, and the mist outlet size is medium. When the ratio of the current ambient humidity to the second preset humidity is greater than or equal to 0.9, the humidification rate of the steam generator is low, the motor speed in the steam storage device is low, and the mist outlet size is small.

[0104] According to an embodiment of the present invention, a humidification control device for an air conditioner corresponding to the humidification control method for an air conditioner is also provided, see [link to relevant documentation]. Figure 7 The diagram shows a structural schematic of an embodiment of the device of the present invention. The air conditioner includes a humidification device, which includes: a steam generator 3 for generating steam; and a steam storage device 4, the air inlet side of which is connected to the steam generator 3 for storing the steam generated by the steam generator 3.

[0105] In the solution of the present invention, such as Figure 7 As shown, the control device of the air conditioner includes: an acquisition unit 102 and a control unit 104.

[0106] The acquisition unit 102 is used to acquire the current ambient humidity of the room where the air conditioner is located; acquire the control command received by the air conditioner to enter the humidification mode; and acquire the steam density value in the steam storage device. The specific functions and processing of the acquisition unit 102 are described in steps S110 to S130.

[0107] The control unit 104 is used to control the steam storage device to open and deliver the steam stored in the steam storage device to the room when it confirms that the current ambient humidity is lower than the first preset humidity, receives an instruction to enter the humidification mode, and the steam density in the steam storage device is greater than the preset density value. The specific functions and processing of the control unit 104 are described in step S140.

[0108] The above solution involves installing a steam generator for producing humidified steam and a steam storage device for storing steam within the humidification unit of the air conditioner. The steam storage device is located at the steam outlet of the steam generator, and its inlet is connected to the outlet of the steam generator, allowing the steam generated by the steam generator to enter the steam storage device through a pipeline and be stored in advance. When the current ambient humidity is confirmed to be lower than a first preset humidity, the air conditioner enters humidification mode, and the current steam density in the steam storage device is greater than a preset density value, it can be determined that the user is feeling unwell and has issued a humidification command. Therefore, humidification is necessary to adjust the indoor humidity. Furthermore, the fact that the current steam density in the steam storage device is greater than the preset density value ensures that the humidification unit can quickly and abundantly release steam to increase indoor humidity. Therefore, when all the above conditions are met, the steam storage device is turned on, and the humidification device of the air conditioner begins to produce mist, delivering a large amount of pre-generated and stored steam to the room, thereby rapidly increasing the indoor humidity in a short period of time, thus achieving the technical effect of quickly improving the indoor environmental humidity and user comfort.

[0109] In other embodiments, the humidification control device of the air conditioner further includes: the acquisition unit 102, which acquires the current operating mode of the air conditioner before confirming that the current ambient humidity is lower than a first preset humidity; when the operating mode is confirmed to be a cooling mode or a heating mode; and, after confirming that the current ambient humidity is lower than the first preset humidity, and before confirming whether an instruction to enter the humidification mode has been received, the control unit 104, if confirming that the current ambient humidity is lower than the first preset humidity, controls the steam generator to turn on, so that the steam generator can generate steam in advance and store it in the steam storage device; then, performs an operation to confirm whether the steam density in the steam storage device is greater than a preset density value; if the steam density in the steam storage device is confirmed to be greater than the preset density value, performs an operation to confirm whether an instruction to enter the humidification mode has been received. The specific functions and processing of the acquisition unit 102 and the control unit 104 are described in steps S210 and S220.

[0110] In either cooling or heating mode, prolonged operation of an air conditioner inevitably leads to a decrease in indoor humidity. Users are highly likely to activate the humidification mode due to this drop. Therefore, to ensure the air conditioner can deliver a large amount of steam promptly when humidification is activated, a steam generator is activated when the current ambient humidity is confirmed to be below a first preset humidity level. This generates steam and stores it in a steam storage device before the humidification mode is activated. By generating and storing steam in advance, when a humidification signal is received, the steam storage device will already contain a sufficient density of steam, allowing a large amount of steam to quickly enter the room and rapidly increase indoor humidity, thus significantly improving user comfort.

[0111] In some embodiments, the humidification device further includes a water tank 2, which is connected to the water inlet side of the steam generator 3, and a heat exchange device is provided in the water tank; the control device of the air conditioner further includes: before the steam generator is turned on, the control unit 104 controls the heat exchange device in the water tank to start, so that the water temperature in the water tank decreases or increases; the specific functions and processing of the control unit 104 are described in step S230.

[0112] In this way, when the air conditioner is in cooling or heating mode, the simultaneous activation of humidification can achieve a balanced regulation of temperature and humidity, ensuring that the air conditioner maintains optimal temperature and humidity levels whether cooling or heating, providing users with the most comfortable experience.

[0113] In some embodiments, the humidification control device of the air conditioner further includes: the acquisition unit 102, which acquires the current operating mode of the air conditioner before confirming that the current ambient humidity is lower than a first preset humidity; when the operating mode is confirmed to be a fan-operated mode; and, after confirming whether an instruction to enter the humidification mode has been received, and before confirming whether the steam density in the steam storage device is greater than a preset density value, the control unit, if confirming that the current ambient humidity is lower than the first preset humidity and confirming that an instruction to enter the humidification mode has been received, controls the steam generator to turn on, so that the steam generator can generate steam in advance and store it in the steam storage device; then, performs the operation of confirming whether the steam density in the steam storage device is greater than the preset density value. The specific functions and processing of the acquisition unit 102 and the control unit 104 are described in steps S310 and S320.

[0114] When the air conditioner is in fan mode, it cannot predict the possibility of insufficient humidity in the indoor environment as it can in cooling and heating modes. Therefore, to avoid wasting energy by turning on the steam generator prematurely, the air conditioner only considers the indoor environment to need humidification when it confirms that it has entered humidification mode. As a result, it controls the steam generator to turn on, generates steam, and stores the generated steam in the steam storage device. This can minimize unnecessary energy waste and consumption, and save energy.

[0115] In some embodiments, the humidification control device of the air conditioner further includes: the acquisition unit 102, used to acquire the relationship between the steam density in the steam storage device and the preset density value; when the steam density in the steam storage device is less than the preset density value; the control unit 104, used to control the steam generator to turn on until the steam density in the steam storage device is greater than the preset density value; the specific functions and processing of the acquisition unit 102 and the control unit 104 are described in steps S410 and S420.

[0116] Most current air conditioner humidifiers automatically activate when the air conditioner receives a humidification command, releasing the generated steam into the room. However, at this point, the humidifier has just started, producing very little steam, which is barely perceptible to the user. This results in low overall humidification efficiency and no noticeable feedback from the user. Therefore, to ensure humidification efficiency, this invention ensures that the steam density in the steam storage device is greater than a preset value before the steam is released into the room. Specifically, in the case of a fan-operated humidifier that only starts operating and generating steam upon receiving a humidification command, the steam generator is activated, but the steam storage device remains closed. The steam generated by the generator is continuously stored in the storage device until the steam density exceeds the preset value, at which point the storage device is activated, allowing steam to enter the room. Because the volume of the steam storage device is significantly smaller than the volume of the room, steam can fill the steam storage device in a short time. When the steam storage device is activated, a large amount of steam enters the room at the same time. The humidification effect on the local area of ​​the room is more significant than that of a small amount of humid steam delivered over a long period of time. This achieves a rapid increase in indoor humidity and improves the user's comfort experience.

[0117] In some embodiments, the humidification control device of the air conditioner further includes: the control unit 104, which controls the steam storage device to open by: controlling the mist output speed of the steam storage device to be high when it is opened; and controlling the mist output amount of the steam storage device to be large when it is opened; the specific functions and processing of the control unit 104 are described in steps S510 and S520.

[0118] Therefore, when a humidification mode command is received and the humidification mode is activated, the wet steam in the steam storage device can be delivered to the room at the fastest speed, thereby rapidly improving the indoor humidity environment and enhancing the user's comfort experience.

[0119] In some embodiments, the humidification control device of the air conditioner further includes: the acquisition unit 102, which acquires the ratio of the current ambient humidity to the second preset humidity after controlling the steam storage device to turn on; and the control unit 104, which adjusts the humidification speed of the steam generator, the mist output speed of the steam storage device, and the mist output of the steam storage device according to the ratio; the specific functions and processing of the acquisition unit 102 and the control unit 104 are described in steps S610 and S620.

[0120] In some embodiments, the control unit 104 further includes adjusting the humidification speed of the steam generator, the mist exit speed of the steam storage device, and the mist output of the steam storage device according to the ratio as follows: when the ratio is less than a first threshold, the humidification speed of the steam generator is controlled to be high, the mist exit speed of the steam storage device is controlled to be high, and the mist output of the steam storage device is controlled to be large; when the ratio is greater than or equal to the first threshold and less than a second threshold, the humidification speed of the steam generator is controlled to be medium, the mist exit speed of the steam storage device is controlled to be medium, and the mist output of the steam storage device is controlled to be medium; when the ratio is greater than or equal to the second threshold, the humidification speed of the steam generator is controlled to be low, the mist exit speed of the steam storage device is controlled to be low, and the mist output of the steam storage device is controlled to be small.

[0121] Therefore, in the early stage of humidification, when the ratio between the current ambient humidity and the second preset humidity is low, humidification is accelerated to provide a large amount of humidified steam, so that the room humidity can be increased quickly. In the later stage of humidification, when the ambient humidity is close to the second preset humidity, humidification is slowed down to reduce the output of humidified steam, prevent over-adjustment, and avoid excessive humidity affecting comfort. This plays a buffering role, thereby achieving intelligent regulation of indoor ambient humidity.

[0122] According to embodiments of the present invention, an air conditioner is also provided, including a humidification control device as described in the foregoing embodiments. See also... Figure 8 Specifically, in some embodiments, the indoor unit of the air conditioner includes a base shell 1, a water tank 2, a steam generator 3, a steam storage device 4, a steam storage device motor 5, an indoor fan motor 6, a hose 7, and a cross-flow fan blade 8.

[0123] Water tank 2, steam generator 3, and steam storage device 4 are sequentially installed on the bottom casing 1 of the indoor unit of the air conditioner. Water tank 2 has an opening at its bottom near the steam generator, and its top provides a water inlet for users to add water when needed. The steam generator has an opening near the water tank, connected to the outlet at the bottom of the water tank, serving as the steam inlet. An opening on the other side of the steam generator serves as the steam outlet, connected to the steam storage device. Thus, the wet steam generated by the steam generator 3 is transported through a pipe from the outlet to the steam storage device 4 and stored there. A mist outlet is located at the bottom of the steam storage device 4, and it is connected to a flexible hose 7, which leads to the cross-flow fan blade 8 and ultimately into the room.

[0124] Therefore, when the indoor unit of the air conditioner is running, the humidification device, consisting of water tank 2, steam generator 3, and steam storage device 4, is activated and stores the generated steam in the steam storage device 4. When a command to enter humidification mode is received, and the humidity and steam density conditions in the above embodiment are met, the mist outlet of the steam storage device opens. At the same time, the steam generator 3 continues to work, continuously generating steam, and the motor 5 of the steam storage device also runs, accelerating the flow and transportation of the humid steam in the steam storage device. Thus, the humid steam stored in the steam storage device is transmitted to the cross-flow fan blades 8 via the hose 7. As the indoor unit of the air conditioner operates, the indoor fan motor 6 drives the cross-flow fan blades 8 to rotate continuously, and the humid steam transmitted to the cross-flow fan blades 8 is also transported into the room with the rotation of the fan blades. In this way, the indoor humidity can be rapidly increased after entering humidification mode. At the same time, the continuous operation of the steam generator ensures a continuous supply of steam, avoiding interruption of humidification.

[0125] In other embodiments, the water tank also includes a level detector, which can be installed at the bottom of the water tank. The level detector can monitor the water level inside the water tank in real time. When it detects that the water level in the water tank is insufficient, it can send a reminder to the user that the water is low, so that the user can add water as soon as possible to avoid running the tank empty.

[0126] In other embodiments, the steam storage device also includes a steam density sensor, which can detect the current steam density value in the steam storage device. When the detected humid steam in the steam storage device reaches a certain density value, it can send a signal to remind the user or processor that the steam storage device has accumulated enough humid steam. At this time, the steam generator can be controlled to stop working to save energy; or the user or processor can be notified that entering the humidification mode can achieve the effect of rapid humidification.

[0127] In some embodiments, the humidification control logic of the air conditioner is described in [reference needed]. Figures 9-11The following will explain in detail the humidification control method and operation mode of the air conditioner under different operating modes.

[0128] like Figure 9 This describes the humidification control method for air conditioners in cooling mode. Specifically,

[0129] When it is determined that the air conditioner has entered the cooling mode, the air conditioner is equipped with a module to obtain the current ambient humidity. It obtains the current ambient humidity and determines the relationship between the current ambient humidity h and the first preset humidity h1.

[0130] When the current ambient humidity h is less than the first preset humidity h1, the humidity in the environment is considered to be a suitable humidity. At this time, for energy saving, the humidification device in the air conditioner is turned off.

[0131] When the current ambient humidity h is greater than the first preset humidity h1, it is assumed that the humidity in the environment may further decrease under the continuous operation of the air conditioner, causing user discomfort. Therefore, to ensure rapid humidification when the user activates the humidification mode, the humidification device in the air conditioner is activated after determining that the current ambient humidity h is greater than the first preset humidity h1, even though the user has not yet issued a humidification command. At this time, the steam generated in the humidification device is not directly delivered to the room, but is transported through pipes from the steam generator and stored in the steam storage device, awaiting further instructions from the air conditioner.

[0132] During the operation of the steam generator, the heat exchange device inside the water tank—specifically, the cooling device (heat exchange device for cooling) when the air conditioner is in cooling mode—will be activated to cool the water in the tank. This ensures that the water temperature in the tank matches the current cooling temperature of the air conditioner. Consequently, when the water in the tank is transformed into humid steam by the steam generator, it is also low-temperature steam. When this steam is discharged into the room, it ensures consistent indoor temperature and humidity, maintains a balanced indoor environment, and improves human comfort.

[0133] At the same time, the steam density sensor in the steam storage device detects the current steam density value in the steam storage device in real time. When the detected wet steam in the steam storage device reaches a certain density value, it can send a signal to remind the user or processor that the steam storage device has accumulated enough wet steam. At this time, it can control the steam generator to stop working to save energy; or it can notify the user or processor that entering the humidification mode can achieve the effect of rapid humidification.

[0134] When a command to enter humidification mode is received from the user or the air conditioner, the air conditioner is confirmed to enter humidification mode. At this time, it is necessary to determine whether the wet steam in the current steam storage device has reached a certain density value. If the wet steam in the current steam storage device is lower than the preset density value, it is considered that there is not enough wet steam. At this time, the steam storage device will not be turned on, but the humidification device will continue to run, continuously generating wet steam and storing it in the steam storage device until the wet steam in the current steam storage device is higher than the preset density value.

[0135] When the humid steam in the current steam storage device is higher than the preset density value, the steam storage device is turned on. At this time, the ratio of the current ambient humidity to the second preset humidity is obtained; and the humidification speed of the steam generator, the mist output speed of the steam storage device, and the mist output of the steam storage device are adjusted according to the ratio, thereby achieving precise control of humidification efficiency.

[0136] like Figure 10 This describes the humidification control method for air conditioners in heating mode. Specifically,

[0137] When it is determined that the air conditioner has entered the heating mode, the air conditioner is equipped with a module to obtain the current ambient humidity. It obtains the current ambient humidity and determines the relationship between the current ambient humidity h and the first preset humidity h2.

[0138] When the current ambient humidity h is less than the first preset humidity h2, the humidity in the environment is considered to be a suitable humidity. At this time, for energy saving, the humidification device in the air conditioner is turned off.

[0139] When the current ambient humidity h is greater than the first preset humidity h2, it is assumed that the humidity in the environment may further decrease under the continuous operation of the air conditioner, causing user discomfort. Therefore, to ensure rapid humidification when the user activates the humidification mode, the humidification device in the air conditioner is activated after determining that the current ambient humidity h is greater than the first preset humidity h1, even though the user has not yet issued a humidification command. At this time, the steam generated in the humidification device is not directly delivered to the room, but is transported through pipes from the steam generator and stored in the steam storage device, awaiting further instructions from the air conditioner.

[0140] During the operation of the steam generator, the heat exchange device inside the water tank—specifically, the heating device when the air conditioner is in heating mode—will be activated to heat the water in the tank. This ensures that the water temperature matches the current heating temperature of the air conditioner. Consequently, when the water in the tank is transformed into humid steam by the steam generator, it becomes high-temperature steam and is discharged into the room. This ensures consistent indoor temperature and humidity, maintains a balanced indoor environment, and improves human comfort.

[0141] At the same time, the steam density sensor in the steam storage device detects the current steam density value in the steam storage device in real time. When the detected wet steam in the steam storage device reaches a certain density value, it can send a signal to remind the user or processor that the steam storage device has accumulated enough wet steam. At this time, it can control the steam generator to stop working to save energy; or it can notify the user or processor that entering the humidification mode can achieve the effect of rapid humidification.

[0142] When a command to enter humidification mode is received from the user or the air conditioner, the air conditioner is confirmed to enter humidification mode. At this time, it is necessary to determine whether the wet steam in the current steam storage device has reached a certain density value. If the wet steam in the current steam storage device is lower than the preset density value, it is considered that there is not enough wet steam. At this time, the steam storage device will not be turned on, but the humidification device will continue to run, continuously generating wet steam and storing it in the steam storage device until the wet steam in the current steam storage device is higher than the preset density value.

[0143] When the humid steam in the current steam storage device is higher than the preset density value, the steam storage device is turned on. At this time, the ratio of the current ambient humidity to the second preset humidity is obtained; and the humidification speed of the steam generator, the mist output speed of the steam storage device, and the mist output of the steam storage device are adjusted according to the ratio, thereby achieving precise control of humidification efficiency.

[0144] like Figure 11 This describes the humidification control method for air conditioners in fan mode. Specifically,

[0145] When it is determined that the air conditioner has entered the air supply mode, the air conditioner is equipped with a module to obtain the current ambient humidity. It obtains the current ambient humidity and determines the relationship between the current ambient humidity h and the first preset humidity h3.

[0146] When the current ambient humidity h is less than the first preset humidity h3, the humidity in the environment is considered to be a suitable humidity. At this time, for energy saving, the humidification device in the air conditioner is turned off.

[0147] When the current ambient humidity h is greater than the first preset humidity h3, the air conditioner will not turn on the heat exchange device in the air supply mode, so it is not easy to change the humidity of the current indoor environment. Therefore, for energy saving, the humidification device of the air conditioner will not turn on automatically, but will wait for further instructions from the air conditioner.

[0148] When a command to enter humidification mode is received from the user or the air conditioner, it is determined that the air conditioner needs to enter humidification mode. At this time, the steam generator is turned on to generate steam and the steam density value in the steam storage device is monitored.

[0149] When the amount of wet steam in the current steam storage device is lower than the preset density value, it is considered that there is not enough wet steam. At this time, the steam storage device will not be turned on, but the humidification device will continue to run, continuously generating wet steam and storing it in the steam storage device until the amount of wet steam in the current steam storage device is higher than the preset density value.

[0150] When the humid steam in the current steam storage device is higher than the preset density value, the steam storage device is turned on. At this time, the ratio of the current ambient humidity to the second preset humidity is obtained; and the humidification speed of the steam generator, the mist output speed of the steam storage device, and the mist output of the steam storage device are adjusted according to the ratio, thereby achieving precise control of humidification efficiency.

[0151] The preset humidity value can be the same or different in cooling mode, heating mode, and air supply mode.
