[0044] At present, most air conditioners such as the duct machine at the heat exchange end of fluorine machines and the fan coil unit at the heat exchange end of water machines do not have a humidification function, resulting in the inability to meet some application scenarios that require adjusting air humidity. And some existing air conditioner indoor units with a humidification function have their humidification modules embedded inside the air conditioner indoor unit, resulting in a larger volume of the air conditioner indoor unit.

[0045] In view of this, the present invention provides an air conditioner indoor unit, aiming to solve the problem that the volume of the air conditioner indoor unit is relatively large because the humidification module is embedded inside it. Among them, Figures 1 to 2A structural schematic diagram of an embodiment of the air conditioner indoor unit provided by the present invention. Figure 3 A structural schematic diagram of a control device for a hardware operating environment involved in the embodiment solution of the present invention; Figure 4 A flowchart of the provided humidification control method.

[0046] Please refer to Figure 1 and Figure 2 As shown in FIGS. and, the air conditioner indoor unit 100 includes a housing 1, a humidifier, and a humidifying pipe 3. The housing 1 forms an air duct. The humidifier is disposed in the housing 1 to form humidifying water mist. The humidifying pipe 3 communicates with the spray port of the humidifier. The humidifying pipe 3 includes a humidifying pipe section 3 disposed in the air duct. The humidifying pipe section 3 is provided with a humidifying port 31 for spraying the humidifying water mist into the air duct.

[0047] In the technical solution of the present invention, the housing 1 forms an air duct for heat exchange with indoor air. The humidifier is disposed outside the housing 1 to avoid occupying the space inside the housing 1, which helps to reduce the volume of the housing 1. The humidifying pipe 3 communicates with the spray port of the humidifier to introduce the humidifying water mist formed by the humidifier to a preset position. The humidifying pipe 3 includes a humidifying pipe section 3 disposed in the air duct. The humidifying pipe section 3 is provided with a humidifying port 31 for spraying the humidifying water mist into the air duct so that the humidifying water mist in the humidifying pipe section 3 can be promptly carried out of the housing 1 by the air in the air duct. In this way, by disposing the humidifier outside the housing 1, the humidifier 2 does not occupy the space inside the housing 1, which helps to reduce the volume of the housing 1. By providing the humidifying pipe 3, the humidifying water mist formed by the humidifier can be introduced into the air duct, and through the humidifying port 31 disposed in the air duct, the humidifying water mist can be sprayed into the air duct, so that the humidifying water mist can be blown out of the housing 1 by the air in the air duct, enabling the user to observe the humidifying water mist, thereby enabling the air conditioner indoor unit 100 to achieve humidification visualization.

[0048] It should be noted that, in order to control the humidifier to humidify, the air conditioner indoor unit 100 further includes a control device. Please refer to Figure 3, the control device may include: a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display) and an input unit such as a keyboard (Keyboard). Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a WI-FI interface). The memory 1005 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0049] In some embodiments of the present invention, the humidifier includes an ultrasonic vibration sheet. Since the ultrasonic humidifier has high humidification efficiency and low energy consumption, the ultrasonic vibration sheet is adopted, which can not only quickly generate humidification water mist but also reduce the power consumption of the humidifier, which is beneficial to reducing the use cost of the air conditioner indoor unit 100. Of course, in other embodiments, the humidifier may also be a direct evaporation type humidifier or a thermal evaporation type humidifier, etc., and the present invention does not limit this.

[0050] There are various connection methods between the humidifier and the housing 1. The humidifier may be welded to the housing 1, adhered to the housing 1, or screwed to the housing 1, etc. The present invention does not limit this. Specifically, in this embodiment, the humidifier is detachably installed on the housing 1. In this way, a detachable connection structure is adopted to facilitate the loading and unloading of the humidifier, thereby facilitating subsequent maintenance or replacement. Further, there are various detachable connection methods. For example, it may be a screw connection structure or a snap connection structure, etc. The present invention does not limit this.

[0051] In some embodiments of the present invention, the air conditioner indoor unit 100 further includes a heat exchanger 4 and a fan 5 provided in the air duct. The humidifying pipe 3 is provided between the heat exchanger 4 and the fan 5. In this way, a part of the humidification water mist will be blown onto the fins of the heat exchanger 4 to increase the evaporation efficiency of the water mist, and another part of the humidification water temperature will be directly blown into the room by the fan 5 from the gaps between the fins of the heat exchanger 4 to increase the humidity in the room.

[0052] The number of the humidifying openings 31 can be one or multiple, and the present invention does not limit this. Specifically, in this embodiment, multiple humidifying openings 31 are provided, and the multiple humidifying openings 31 are arranged at intervals along the axial direction of the humidifying pipe 3. In this way, by providing the multiple humidifying openings 31, the humidifying water mist in the humidifying pipe 3 can be quickly discharged. Compared with using a larger single humidifying opening 31, providing multiple humidifying openings 31 not only helps to quickly discharge the humidifying water mist in the humidifying pipe 3 to increase the supply amount of the humidifying water mist, but also can effectively reduce the influence of the opening on the strength of the humidifying pipe 3, thereby helping to improve the service life of the humidifying pipe 3.

[0053] In some embodiments of the present invention, the air conditioner indoor unit 100 further includes a water inlet pipe 6 and a drain pipe 7 that communicate with the humidifier. In this way, by providing the water inlet pipe 6, water can be supplied to the humidifier, and by providing the drain pipe 7, the water in the humidifier can be discharged for subsequent maintenance or replacement.

[0054] The present invention also provides an air conditioner, and the air conditioner includes the above-mentioned air conditioner indoor unit 100. It should be noted that the structure of the air conditioner indoor unit 100 in the air conditioner can refer to the embodiment of the above-mentioned air conditioner indoor unit 100, and will not be elaborated here; since the above-mentioned air conditioner indoor unit 100 is used in the air conditioner provided by the present invention, therefore, the embodiments of the air conditioner provided by the present invention include all the technical solutions of all the embodiments of the above-mentioned air conditioner indoor unit 100, and the achieved technical effects are also exactly the same, and will not be elaborated here.

[0055] Those skilled in the art can understand that Figure 3 the structure shown in

[0056] does not constitute a limitation on the control device, and may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements. Figure 3 As shown in

[0057] In Figure 3 the control device shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the control device of the present invention can be arranged in the control device. The control device calls the humidifying control program stored in the memory 1005 through the processor 1001 and executes the humidifying control method provided by the embodiment of the present invention.

[0058] In Figure 3In the control device shown, the control program of the air conditioner stored in the memory 1005 is called by the processor 1001. The humidification control program includes the following steps:

[0059] After obtaining the humidification instruction, control the compressor to operate at a frequency not exceeding the first preset frequency, and obtain the current indoor temperature;

[0060] Based on the current temperature, determine the humidification strategy of the air conditioner indoor unit 100, and control the ultrasonic vibration sheet of the humidifier and the fan 5 to operate according to the humidification strategy;

[0061] After operating for a preset duration, adjust the fan 5 to operate at the user-set speed, and adjust the compressor to operate at the user-set frequency.

[0062] Further, the determining the humidification strategy of the air conditioner indoor unit 100 based on the current temperature and controlling the ultrasonic vibration sheet of the humidifier and the fan 5 to operate according to the humidification strategy includes:

[0063] When the current temperature is less than the first preset temperature, control all the ultrasonic vibration sheets in the humidifier to work at the maximum oscillation frequency, and control the fan 5 to work at the first speed;

[0064] When the current temperature is greater than or equal to the first preset temperature, control all the ultrasonic vibration sheets in the humidifier to work at the maximum oscillation frequency, and control the fan 5 to work at the second speed, where the first speed is greater than the second speed.

[0065] Further, the information in the humidification instruction includes the target temperature and the target relative humidity;

[0066] After the adjusting the fan 5 to operate at the user-set speed and adjusting the compressor to operate at the user-set frequency after operating for a preset duration, it further includes:

[0067] Obtain the current indoor relative humidity;

[0068] Determine the current absolute humidity according to the current temperature and the current relative humidity;

[0069] Determine the target absolute humidity according to the target temperature and the target relative humidity;

[0070] Determine the humidity difference according to the current absolute humidity and the target absolute humidity;

[0071] Determine the adjustment strategy of the humidifier according to the humidity difference.

[0072] Further, the determining the adjustment strategy of the humidifier according to the humidity difference includes:

[0073] When the humidity difference is greater than or equal to a first preset humidity difference, adjust all ultrasonic vibrating plates in the humidifier to operate at a first oscillation frequency;

[0074] When the humidity difference is less than the first preset humidity difference and greater than a second preset humidity difference, select a first specified number of ultrasonic vibrating plates in the humidifier to operate at a second oscillation frequency, where the first preset humidity difference is greater than the second preset humidity difference, and the first oscillation frequency is greater than the second oscillation frequency;

[0075] When the humidity difference is less than the second preset humidity difference, select a second specified number of ultrasonic vibrating plates in the humidifier to operate at the second oscillation frequency, where the second specified number is less than the first specified number.

[0076] Based on the above hardware structure, the present invention proposes a humidification control method. The humidification control method operates through the ultrasonic vibrating plates and the air conditioner of the humidifier to introduce the humidification water mist formed by the humidifier into the air duct, so as to blow the humidification water mist in the air duct out of the housing 1, enabling the user to observe the humidification water mist, thereby enabling the air conditioner indoor unit 100 to achieve visual humidification.

[0077] Please refer to Figure 4 , the first process schematic diagram of the humidification control method provided by the present invention.

[0078] The humidification control method includes;

[0079] S10: After obtaining a humidification instruction, control the compressor to operate at a frequency not exceeding a first preset frequency, and obtain the current temperature indoors;

[0080] It should be noted that there are various ways to obtain a humidification instruction, which can be obtained through a power switch or a remote control, etc. The present invention does not limit this. In addition, humidification is usually required only in winter. However, in winter, the air conditioner generally needs to perform heating to meet the heating needs of users. Therefore, humidification is usually carried out when the air conditioner is heating. When the air conditioner is heating, the exhaust port of the compressor is connected to the indoor heat exchanger 4 so that the indoor heat exchanger 4 can heat the indoor air. Since the higher the compressor frequency, the higher the temperature of the refrigerant discharged by the compressor and the higher the temperature of the indoor heat exchanger 4, and too high a temperature will cause the humidification water mist to be evaporated before flowing out of the housing 1, making the user unable to see the humidification water mist and affecting the user experience. Therefore, the frequency of the compressor needs to be limited before humidification to prevent the humidification water mist from being evaporated. Further, the first preset frequency can be a fixed value or a value range, and the present invention does not limit this.

[0081] S20: Determine the humidification strategy of the air conditioner indoor unit 100 based on the current temperature, and control the ultrasonic vibrating sheet of the humidifier and the blower 5 to operate according to the humidification strategy;

[0082] It should be noted that generally, the higher the rotation speed of the blower 5, the faster the evaporation rate of the humidification water mist, and vice versa, the lower the evaporation rate of the humidification water mist.

[0083] S30: After running for a preset duration, adjust the blower 5 to operate at the user-set rotation speed, and adjust the compressor to operate at the user-set frequency.

[0084] It should be noted that the preset duration can be half an hour, one hour, etc., and can be specifically set according to needs. The present invention does not limit this.

[0085] In this embodiment, after obtaining the humidification instruction, control the compressor to operate at a frequency not exceeding the first preset frequency to prevent the temperature of the indoor heat exchanger 4 from being too high. Then, obtain the first current temperature, determine the humidification strategy according to the first current temperature, and then control the ultrasonic vibrating sheet of the humidifier and the blower 5 according to the humidification strategy, so that the humidification water mist can quickly flow out of the housing 1, so that the user can observe that the air conditioner indoor unit 100 starts to perform humidification work. After the air conditioner indoor unit 100 humidifies for the preset duration, then adjust the blower 5 to operate at the user-set rotation speed, and at the same time adjust the compressor to operate at the user-set frequency, so as to meet the user's humidification requirements. In this way, by controlling the ultrasonic vibrating sheet, the compressor and the blower 5 to work, when humidification starts, the air conditioner indoor unit 100 can spray water mist into the room, so that the user can observe that the air conditioner indoor unit 100 starts to perform humidification work, and after the air conditioner indoor unit 100 humidifies for the preset duration, the blower 5 and the compressor can respectively operate at the user-set rotation speed and set frequency, so as to meet the user's customized needs, thereby helping to improve the user experience.

[0086] Further, step S20 includes:

[0087] S21: When the first current temperature is less than the first preset temperature, control all the ultrasonic vibrating sheets in the humidifier to work at the maximum oscillation frequency, and control the blower 5 to work at the first rotation speed;

[0088] It should be noted that the first rotation speed can be set according to needs. The present invention does not limit this. Further, the first rotation speed is not higher than 800 rpm.

[0089] S22: When the first current temperature is greater than or equal to the first preset temperature, control all the ultrasonic vibrating plates in the humidifier to work at the maximum oscillation frequency, and control the blower 5 to work at the second rotation speed, where the first rotation speed is greater than the second rotation speed.

[0090] It should be noted that the second rotation speed can be set as needed, and the present invention does not limit this. Further, the first rotation speed is not higher than 200 rpm.

[0091] In this embodiment, in order to facilitate the user to observe the humidifying water mist, it is necessary to increase the supply amount of the water mist. Therefore, the ultrasonic vibrating plates need to work at the maximum oscillation frequency to ensure the formation of enough humidifying water mist. When the first current temperature is less than the first preset temperature, it indicates that the indoor temperature is relatively low and the humidifying water mist is not easily vaporized. Therefore, it is necessary to increase the rotation speed of the blower 5 so that the humidifying water mist can flow out of the housing 1 in time. At this time, control the blower 5 to work at the first rotation speed to increase the wind speed in the air duct, so as to prevent the humidifying water mist from accumulating in the housing 1 and enable the humidifying water mist to flow out of the housing 1 in time so that the user can observe the humidifying water mist; when the first current temperature is greater than or equal to the first preset temperature, it indicates that the indoor temperature is relatively high and the humidifying water mist is easily vaporized and becomes invisible. Therefore, it is necessary to reduce the rotation speed of the blower 5. At this time, control the blower 5 to work at the second rotation speed to reduce the vaporization rate of the humidifying water mist in the air duct, so that the humidifying water mist can flow out of the housing 1 so that the user can observe the humidifying water mist.

[0092] It should be noted that the first preset temperature can be a fixed value or a value range, and the present invention does not limit this.

[0093] In some embodiments of the present invention, the information in the humidifying instruction includes the target temperature and the target relative humidity;

[0094] After step S30, it further includes:

[0095] S41: Obtain the current relative humidity and the second current temperature in the room;

[0096] S42: Determine the current absolute humidity according to the second current temperature and the current relative humidity;

[0097] S43: Determine the target absolute humidity according to the target temperature and the target relative humidity;

[0098] S44: Determine the humidity difference according to the current absolute humidity and the target absolute humidity;

[0099] S45: Determine the adjustment strategy of the humidifier according to the humidity difference.

[0100] In this embodiment, since the service life of the air conditioner indoor unit 100 is relatively long, and the service life of the humidifier is related to its oscillating sheet. Generally speaking, the higher the oscillation frequency of the ultrasonic oscillating sheet and the longer the oscillation duration, the shorter its service life. Therefore, by obtaining the second current temperature and the current relative humidity to determine the current absolute humidity, then determining the target absolute humidity according to the target temperature and the target relative humidity, calculating the humidity difference according to the current absolute humidity and the target absolute humidity, and controlling the oscillation number and oscillation frequency of the ultrasonic oscillating sheet of the humidifier according to the humidity difference. In this way, the oscillation number and oscillation frequency of the ultrasonic oscillating sheet are controlled by the humidity difference to extend the service life of the ultrasonic oscillating sheet, thereby helping to extend the service life of the humidifier.

[0101] Further, step S45 includes:

[0102] S451: When the humidity difference is greater than or equal to the first preset humidity difference, adjust all the ultrasonic oscillating sheets in the humidifier to work at the first oscillation frequency;

[0103] It should be noted that the first preset humidity difference can be a fixed value or a value range, and the present invention does not limit this.

[0104] S452: When the humidity difference is less than the first preset humidity difference and greater than the second preset humidity difference, select the first specified number of ultrasonic oscillating sheets in the humidifier to work at the second oscillation frequency, where the first preset humidity difference is greater than the second preset humidity difference, and the first oscillation frequency is greater than the second oscillation frequency;

[0105] S453: When the humidity difference is less than the second preset humidity difference, select the second specified number of ultrasonic oscillating sheets in the humidifier to work at the second oscillation frequency, where the second specified number is less than the first specified number.

[0106] In this embodiment, when the humidity difference is greater than or equal to the first preset humidity difference, it indicates that the gap between the current absolute humidity and the target absolute humidity is large, and it is necessary to increase the supply of humidifying water mist to quickly increase the indoor humidity. At this time, all the ultrasonic vibrating plates in the humidifier are controlled to work at the first oscillation frequency to accelerate the generation rate of the humidifying water mist and increase the supply of the humidifying water mist, which is beneficial to quickly increase the indoor humidity. When the humidity difference is less than the first preset humidity difference and greater than the second preset humidity difference, it indicates that the gap between the current absolute humidity and the target absolute humidity is medium, and it is necessary to control the number and frequency of the ultrasonic vibrating plates in the humidifier. At this time, the first specified number of ultrasonic vibrating plates in the humidifier is selected to work at the second oscillation frequency to reduce the oscillation number and oscillation frequency of the ultrasonic vibrating plates in the humidifier, which is beneficial to extend the service life of the humidifier. When the humidity difference is less than the second preset humidity difference, it indicates that the gap between the current absolute humidity and the target absolute humidity is small, and it is necessary to reduce the number of ultrasonic vibrating plates in the humidifier. At this time, the second specified number of ultrasonic vibrating plates in the humidifier is selected to work at the second oscillation frequency to further reduce the oscillation number of the ultrasonic vibrating plates in the humidifier. In this way, through the humidity difference, the oscillation number and oscillation frequency of the ultrasonic vibrating plates in the humidifier can be adapted to the humidity difference. The larger the humidity difference, the larger the oscillation number and the oscillation frequency of the ultrasonic vibrating plates, which helps to extend the service life of the ultrasonic vibrating plates in the humidifier.
