Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular provides a control method for an air conditioner. Background Art

[0002] As people's living standards improve, air conditioners are becoming increasingly common in their daily lives and work. This leads to increasing demands for air conditioners' sterilization and anti-virus capabilities. To address this, air conditioners are often equipped with sterilization devices that remove bacteria, viruses, and other substances from the air flowing through them.

[0003] The above-mentioned sterilization devices usually include ultraviolet devices, high-pressure ion sterilization devices, ozone sterilization devices, and silver ion sterilization devices. Among them, ultraviolet devices achieve the purpose of sterilization by irradiating the air or the surface of an object with ultraviolet rays, but their functions are relatively simple. High-pressure ion sterilization devices use high-voltage ionization of air to produce positive and negative ions that can kill bacteria. However, the lifespan of positive and negative ions is short and they are consumed not long after being blown out of the air conditioner. Ozone sterilization devices achieve the purpose of sterilization through the ozone they produce, but ozone itself is a harmful substance. While sterilizing, it is also necessary to treat excess ozone. For this reason, ozone sterilization devices require additional functional modules to treat ozone, resulting in a very complex structure. Silver ion sterilization devices achieve the purpose of sterilization through silver ions, but their initiative is poor and usually require air to pass through the silver ion sterilization device before it can be sterilized. In addition, the above-mentioned types of sterilization devices can usually only achieve the purpose of sterilization and have relatively simple functions. When the air conditioner is running, the doors and windows are usually closed. After running for a long time, a more obvious odor will usually be generated in the indoor space. The above-mentioned sterilization device cannot remove these odors, which seriously reduces the user experience.

[0016] In the technical solution of the present invention, an air conditioner is equipped with an air conditioning device, which includes a photocatalyst and an ultraviolet unit. The photocatalyst is configured to remove odors from the air after being activated. The ultraviolet unit includes a second ultraviolet module and a first ultraviolet module. The second ultraviolet module includes a second lamp board and a second lamp bead arranged on the second lamp board. The first ultraviolet module includes a first lamp board and a first lamp bead arranged on the first lamp board. The second lamp board and the first lamp board are configured to power the first lamp bead and the second lamp bead, thereby ensuring the stable operation of the second ultraviolet module and the first ultraviolet module. The second lamp bead is configured to emit ultraviolet rays that can activate the photocatalyst after being powered on, and the first lamp bead is configured to emit ultraviolet rays that can sterilize the air after being powered on. In this way, on the one hand, the ultraviolet rays emitted by the first lamp bead can remove bacteria, viruses, etc. inside the air conditioner and in the air inside the air conditioner. On the other hand, the ultraviolet rays emitted by the second lamp bead can activate the photocatalyst, and the activated photocatalyst can remove odors from the air. Through this setting, the air can be sterilized and odor removed at the same time, which can better improve the air conditions in the space where the air conditioner is located and enhance the user experience.

[0017] The control method of the present invention includes: obtaining an air quality index of an outdoor environment, determining the range of the air quality index, obtaining the number of people in the space where the air conditioner is located, and controlling the operating mode of a first ultraviolet module and / or a second ultraviolet module based on the range of the air quality index and the number of people. Through this control method, the operating mode of the first ultraviolet module and the second ultraviolet module is controlled according to the range of the air quality index and the number of people, thereby enabling the operating mode of the air conditioning device to be controlled in real time based on the air quality of the outdoor environment and the number of people in the indoor space, so that the sterilization and odor removal intensity can be different according to different actual conditions, thereby better improving the air conditions in the indoor space and saving electricity.

[0018] If the air quality index is greater than the first preset index and the number of people is greater than or equal to the first preset number of people, it means that the air quality of the outdoor environment is very poor, which will cause the air quality of the indoor space to be poor, and there are users active in the indoor space. At this time, the first ultraviolet module is controlled to run the third sterilization mode, and the second ultraviolet module is controlled to run the third deodorization mode. By making the first ultraviolet module and the second ultraviolet module run at a higher power, the sterilization and deodorization treatment are carried out more vigorously, thereby better improving the conditions of the indoor space.

[0019] If the air quality index is less than or equal to a first preset index and the number of people is greater than or equal to the first preset number, it indicates that the air quality of the outdoor environment is not very poor and there are users active in the indoor space. In this case, it is further determined whether the air quality index is greater than a second preset index, and based on the first determination result, the number of people, and the comparison result between the number of males and the number of females, the first UV module is selectively controlled to operate in the first sterilization mode, the second sterilization mode, or the third sterilization mode, and the second UV module is selectively controlled to operate in the first deodorization mode, the second deodorization mode, or the third deodorization mode. In this way, by selectively controlling the operating mode of the first UV module and the second UV module based on the air quality index interval, the number of people, and gender, that is, controlling the operating power of the first UV module and the second UV module, it is possible to better adapt to the actual air quality and the number of people in the indoor space to achieve different sterilization and deodorization levels, ensure that the indoor space conditions can be better improved when there are users active indoors, ensure sterilization and deodorization effects while saving electricity.

[0020] Furthermore, if the air quality index is greater than the second preset index, it means that the air quality of the outdoor environment is not very good. At this time, based on the number of people and the comparison results of the number of males and the number of females, the first ultraviolet module is controlled to operate in the second sterilization mode or the third sterilization mode, and the second ultraviolet module is controlled to operate in the second deodorization mode or the third deodorization mode. When the number of people is greater than the second preset number of people, it means that there are more people in the indoor space. At this time, the first ultraviolet module and the second ultraviolet module are controlled to operate at the maximum power. When the number of people is less than or equal to the second preset number of people, it means that there are fewer people in the indoor space. At this time, when there are more men, the second ultraviolet module is controlled to operate at a higher power, and when there are fewer men, the second ultraviolet module is controlled to operate at a lower power. In this way, the operating mode of the first ultraviolet module and the second ultraviolet module can be controlled based on the comparison results of the number of males and the number of females to achieve different sterilization and deodorization strengths, while ensuring the sterilization and deodorization effects to meet the needs of users and saving electricity. Through the above-mentioned control method, when the air quality index is greater than the second preset index, the operation mode of the first ultraviolet module and the second ultraviolet module is controlled based on the comparison results of the number of people and the number of males and females, so that when the air quality of the outdoor environment is poor, appropriate sterilization and deodorization efforts can be adopted, while ensuring the sterilization and deodorization effects and saving electricity.

[0021] Furthermore, if the air quality is less than or equal to the second preset index, it means that the air quality of the outdoor environment is okay and not very bad. At this time, based on the number of people and the comparison results of the number of males and the number of females, the first ultraviolet module is selectively controlled to operate the first sterilization mode, the second sterilization mode or the third sterilization mode, and the second ultraviolet module is controlled to operate the first odor removal mode, the second odor removal mode or the third odor removal mode.

[0022] If the number of people is less than or equal to the third preset number, it means that there are very few people in the indoor space, so the first ultraviolet module and the second ultraviolet module are controlled not to operate, and there is no need to perform sterilization and deodorization through the air conditioning device. The current air conditions can meet the needs of users.

[0023] If the number of people is greater than the fourth preset number, it means that there are many people in the indoor space. The increase in the number of people will bring bacteria, viruses, etc. to the indoor space, and the body odor of each person will also affect the air conditions of the indoor space. At this time, the first UV module is controlled to run the third sterilization mode, and the second UV module is controlled to run the third deodorization mode, that is, the first UV module and the second UV module are controlled to run at the maximum power, and the sterilization and deodorization treatment are performed with the greatest intensity, reducing the impact of a large number of people on the air conditions, better improving the conditions of the indoor space, and meeting the needs of users.

[0024] If the number of people is less than or equal to the fourth preset number and greater than the third preset number, it indicates that there are a large number of people in the indoor space. However, the number of people and gender differences will affect the air conditions in the indoor space. In this case, it is further determined whether the number of people is greater than or equal to the fifth preset number. Based on the second determination result and the comparison result of the number of males and females, the first UV module is controlled to operate in the first, second, or third sterilization mode, and the second UV module is controlled to operate in the first, second, or third odor removal mode. If the number of people is less than or equal to the fifth preset number, it indicates that there are not many people in the indoor space. In this case, based on the comparison result of the number of males and females, the first UV module is controlled to operate in the first sterilization mode or the second sterilization mode with relatively low power, and the second UV module is controlled to operate in the first or second odor removal mode with relatively low power. If the number of people is greater than the fifth preset number, it indicates that there are still a large number of people in the indoor space. In this case, based on the comparison result of the number of males and females, the first UV module is controlled to operate in the second or third sterilization mode with relatively high power, and the second UV module is controlled to operate in the second or third odor removal mode with relatively high power. This will make it possible to better tailor the number of people and gender ratio in the indoor space to achieve different sterilization and deodorization efforts, while ensuring that the sterilization and deodorization effects meet user needs while also saving electricity.

[0025] Through the above-mentioned control method, when the air quality index is less than or equal to the second preset index, the operation mode of the first ultraviolet module and the second ultraviolet module is controlled based on the number of people and the comparison results of the number of males and the number of females, so that when the air quality of the outdoor environment is relatively good, appropriate sterilization and deodorization efforts can be adopted, while ensuring the sterilization and deodorization effects and saving electricity.

[0043] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely intended to illustrate the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Although this embodiment is described using a wall-mounted air conditioner as an example, it is also applicable to other types of air conditioners, such as ceiling-mounted air conditioners and cabinet air conditioners.

[0044] It should be noted that, in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the two elements. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0045] Current sterilization devices typically only have a sterilization function and are relatively simple. When the air conditioner is operated with doors and windows closed for extended periods, a noticeable odor develops in the indoor space. Current sterilization devices are unable to remove this odor, severely reducing the user experience. To address this, the air conditioner of the present invention controls the operating modes of the first and second UV modules based on the air quality index range and the number of people. This allows for different sterilization and odor removal levels tailored to specific circumstances, thereby improving indoor air conditions while also saving energy.

[0046] In the present invention, a wall-mounted air conditioner is equipped with an air conditioning device, which includes a photocatalyst and an ultraviolet unit. The photocatalyst is configured to remove odors from the air when activated. The ultraviolet unit includes a first ultraviolet module and a second ultraviolet module. The first ultraviolet module includes a first lamp board and a first lamp bead mounted on the first lamp board. The second ultraviolet module includes a second lamp board and a second lamp bead mounted on the second lamp board. The first and second lamp boards are configured to power the first and second lamp bead, thereby ensuring stable operation of the first and second ultraviolet modules. The first lamp bead is configured to emit ultraviolet light to sterilize the air when powered on, and the second lamp bead is configured to emit ultraviolet light to activate the photocatalyst when powered on. In this way, on the one hand, the ultraviolet light emitted by the first lamp bead removes bacteria, viruses, etc. from the interior of the wall-mounted air conditioner and the air inside the wall-mounted air conditioner. On the other hand, the ultraviolet light emitted by the second lamp bead can activate the photocatalyst, and the activated photocatalyst can remove odors from the air. Through such a setting, the air can be sterilized and odor removed at the same time, thereby better improving the air conditions in the space where the wall-mounted air conditioner is located and enhancing the user experience.

[0047] In one possible embodiment, the first lamp bead is a UVC LED lamp bead, and the second lamp bead is a UVA LED lamp bead. The brightness of the UVC LED lamp bead is relatively weak and cannot fully activate the photocatalyst component, but the sterilization effect is very good. The brightness of the UVA LED lamp bead is relatively strong and can fully activate the photocatalyst component, but the penetration is relatively poor and the sterilization effect is average. In this way, by using UVA LED lamp beads and UVC LED lamp beads in combination, it is possible to take into account both sterilization and odor removal, obtain better sterilization and odor removal effects, and better improve the air conditions in the indoor space. Obviously, it is also possible that the second lamp bead is a UVC LED lamp bead and the first lamp bead is a UVA LED lamp bead. Of course, the second lamp bead and the first lamp bead can also be other possible types of lamp beads such as UVB LED lamp beads. However, these methods have the problem of poor sterilization effect or poor odor removal effect.

[0048] It should be noted that the power of the first and second lamp beads can be controlled by controlling the magnitude of the current flowing through them, thereby controlling the operating power of the first and second UV modules. Taking the control of the second UV module as an example, when the external power supply voltage is 12V, the maximum current flowing through the second lamp bead is 900mA, at which point the second UV module operates at its maximum power. When the current flowing through the second lamp bead is 600mA, i.e., two-thirds of the maximum current, the second UV module operates at approximately two-thirds of the maximum power. When the current flowing through the second lamp bead is 300mA, i.e., one-third of the maximum current, the second UV module operates at approximately one-third of the maximum power. The greater the operating power of the first and second lamp beads, the higher the brightness of the first and second lamp beads. The greater the operating power of the first and second lamp beads, the better the sterilization effect of the ultraviolet light emitted by the first lamp bead, and the better the deodorization effect of the photocatalyst activated by the ultraviolet light emitted by the second lamp bead. The lower the brightness of the first and second lamp beads, the lower the operating power of the first and second lamp beads, and the less electrical energy they consume. Obviously, the operating power of the first and second UV modules can also be controlled by controlling the voltage supplying the first and second lamp beads. However, adjusting the voltage is more complicated and requires the addition of an additional voltage regulator.

[0049] In the present invention, the wall-mounted air conditioner is further provided with a detection module, which can detect the number of people in the indoor space and determine the number of males and females in the indoor space.

[0050] It should be noted that the detection module can be an image acquisition module. First, the image acquisition module acquires an image of all human bodies in the indoor space. Then, the human bodies in the image are analyzed using an image recognition method to determine the number of people in the indoor space. The image is then input into a pre-built image gender recognition network model to determine the number of males and females in the indoor space. The image recognition method for determining the number of people in an image based on an image, as well as the construction of an image gender recognition module and the determination of the gender of a human body based on this module are relatively mature technical means and will not be elaborated here. It should be noted that the image acquisition module can be, but is not limited to, a camera, etc.

[0051] Obviously, the detection module may also include an infrared detector and an image acquisition module. The infrared detector includes an infrared transmitter and an infrared receiver. The infrared transmitter emits infrared rays, and the infrared receiver receives infrared rays reflected by the human body, thereby being able to determine the number of people in the indoor space. The image of the indoor space is acquired through the image acquisition module, and then the number of males and females is determined through a pre-built image gender recognition network model. Without departing from the principles of the present application, those skilled in the art can flexibly select specific means for determining the number of people and the gender of the human body according to the specific application scenario, as long as the number of people, the number of males, and the number of females in the indoor space can be determined.

[0052] It should be noted that the wall-mounted air conditioner may not be equipped with a detection module, but instead the user may manually input the number of people, the number of men, and the number of women in the current indoor space. However, the manual input method is not smart enough, is cumbersome, and is easy to forget when starting the air conditioning device.

[0053] Because indoor doors and windows are often not tightly closed, the outdoor air quality can affect the indoor air quality. That is, when the outdoor air quality is poor, the indoor air quality is naturally poor, and when the outdoor air quality is good, the indoor air quality is also good. Therefore, in the present invention, a wall-mounted air conditioner is provided with a communication module that is connected to the internet and can obtain the Air Quality Index (AQI) published online in real time.

[0054] It should be noted that the communication module can be connected to the Internet through wide area network, local area network, WiFi, "WiFi + router with Internet access", Bluetooth, ZIGBEE, NFC, GPRS, 2G / 3G / 4G / 5G, etc.

[0055] Of course, the wall-mounted air conditioner may not be provided with a communication module. Instead, the outdoor air quality index may be obtained through a mobile terminal connected to the wall-mounted air conditioner, and the mobile terminal then transmits the data to the wall-mounted air conditioner. The mobile terminal may be, but is not limited to, a smartphone, a tablet computer, an e-book reader, an MP3 player, an MP4 player, a portable computer, etc. Without departing from the principles of the present application, those skilled in the art may flexibly select a specific method for obtaining the air quality index based on the specific application scenario, as long as the air quality index published on the internet can be obtained in real time.

[0056] It should be noted that the air quality index is typically calculated based on the content of PM2.5, PM10, and pollutants such as SO2, NO2, O3, and CO in the air, in accordance with the national standard GB3095 "Ambient Air Quality Standards." This accurately represents the degree of air pollution. This "Ambient Air Quality Standards" were developed by my country based on the "Air Quality Guidelines" issued by the World Health Organization. Of course, other air quality standards, such as those in the United States, can also be used for calculations, depending on the specific location and environment of the wall-mounted air conditioner.

[0057] In order to realize all the functions of the following control method, in the present invention, the wall-mounted air conditioner further includes a control module, which is respectively connected to the detection module, the communication module, the first ultraviolet module, and the second ultraviolet module, and can determine the interval in which the air quality index is located based on the air quality index queried by the communication module, and can control the operating mode of the first ultraviolet module and the second ultraviolet module based on the interval in which the air quality index is located and the number of people, the number of males, and the number of females detected by the detection module. It should be noted that this control module can physically be a control chip of the wall-mounted air conditioner itself, or a controller specifically used to execute the control method of the present application, or a functional module or functional unit of a general controller.

[0058] Refer to the following Figures 1 to 6 To illustrate possible implementations of the control method for the wall-mounted air conditioner of the present invention.

[0059] like Figure 1 As shown, in a possible implementation manner, the control method of the present invention includes:

[0060] S100: Obtain the air quality index of the outdoor environment;

[0061] S101: Determine the range of the air quality index;

[0062] S102: Obtain the number of people in the space where the wall-mounted air conditioner is located;

[0063] S103: Based on the air quality index interval and the number of people, the operation modes of the first ultraviolet module and the second ultraviolet module are controlled.

[0064] In S100, the air quality of the outdoor environment is obtained through the above-mentioned communication module.

[0065] In S101 , based on the air quality index obtained in S100 , the range of the air quality index is determined.

[0066] Generally, the air quality index calculated according to my country's "Ambient Air Quality Standards" can be divided into 6 levels. Each level corresponds to different air quality, has different impacts on people's health, and requires different precautions. The details are shown in Table 1:

[0067] Table 1

[0068] AQI index grade Precautions 0-50 Level 1 (Excellent) Participate in outdoor activities and breathe fresh air 51-100 Level 2 (Good) Outdoor activities can be carried out normally 101-150 Grade 3 (mild) Sensitive people should reduce outdoor activities that require a lot of physical exertion 151-200 Level 4 (moderate) Greater impact on sensitive groups 201-300 Level 5 (severe) Everyone should reduce outdoor activities appropriately >300 Level 6 (severe) Try not to stay outdoors

[0069] Of course, the various levels listed in Table 1 are merely exemplary descriptions, and those skilled in the art can flexibly select an appropriate grading method according to specific application scenarios, as long as it can fully reflect the actual air pollution level of the outdoor environment.

[0070] In S102, the number of people in the indoor space is obtained through the above detection module.

[0071] In S103 , based on the range of the air quality index determined in S101 and the number of people acquired in S102 , the operation modes of the first ultraviolet module and the second ultraviolet module are controlled.

[0072] Through the above-mentioned control method, the operating mode of the first ultraviolet module and the second ultraviolet module is controlled according to the range of the air quality index and the number of people, so that the operating mode of the air conditioning device can be controlled in real time according to the air quality of the outdoor environment and the number of people in the indoor space, so that it can operate according to different actual conditions to achieve different sterilization and deodorization strengths, thereby better improving the air conditions in the indoor space and saving electricity.

[0073] It should be noted that the above S100 and S102 may be executed simultaneously, or S100 may be executed first and then S102, or S102 may be executed first and then S100.

[0074] It should be noted that, it is also possible to control only the operating mode of the first UV module or the operating mode of the second UV module according to the range of the air quality index and the number of people. For the sake of convenience, this embodiment is described by taking the operating mode of the first UV module and the second UV module as an example.

[0075] In one possible implementation, if the air quality index is greater than a first preset index and the number of people is greater than or equal to the first preset number, for example, the air quality index obtained in S100 is 350, the first preset index is 300, and the first preset number of people is 1. This indicates that the air quality of the outdoor environment is very poor, which will lead to poor air quality in the indoor space, and there are users in the indoor space. In this case, the first UV module is controlled to operate in the third sterilization mode, and the second UV module is controlled to operate in the third deodorization mode. By operating the first and second UV modules at the highest power, sterilization and deodorization are performed with maximum intensity, thereby improving the air conditions in the indoor space.

[0076] In one possible embodiment, if the air quality index is less than or equal to a first preset index and the number of people is greater than or equal to the first preset number, for example, the air quality index obtained in S100 is 250, the first preset index is 300, and the first preset number of people is 1. This indicates that the air quality of the outdoor environment is not extremely poor, the air quality of the indoor space is not very poor, and there are users active in the indoor space. In this case, a further determination is made as to whether the air quality index is greater than a second preset index. Because men and women have different personality traits such as physique and body odor, the degree to which men and women affect the air conditions in indoor spaces and their requirements for air conditions are also different. To improve the air conditions in indoor spaces while saving energy, the first UV module is selectively controlled to operate in the first, second, or third sterilization mode, and the second UV module is controlled to operate in the first, second, or third odor removal mode based on the first determination result, the number of people, and the comparison result between the number of men and women. In this way, the operating modes of the first ultraviolet module and the second ultraviolet module can be selectively controlled based on the air quality index range, the number of people and gender, that is, the operating power of the first ultraviolet module and the second ultraviolet module can be controlled. This can better suit the actual air quality and personnel situation in the indoor space to achieve different sterilization and deodorization intensities, ensuring that the air conditions in the indoor space can be better improved when users are indoors, ensuring the sterilization and deodorization effects while saving electricity.

[0077] It should be noted that, in the present invention, the operating modes of the first UV module include a first sterilization mode, a second sterilization mode, and a third sterilization mode. The first sterilization mode is for the first UV module to operate at a first power, the second sterilization mode is for the first UV module to operate at a second power, and the third sterilization mode is for the first UV module to operate at a third power, wherein the first power is less than the second power, and the second power is less than the third power. The operating modes of the second UV module include a first deodorization mode, a second deodorization mode, and a third deodorization mode. The first deodorization mode is for the second UV module to operate at a fourth power, the second deodorization mode is for the second UV module to operate at a fifth power, and the third deodorization mode is for the second UV module to operate at a sixth power, wherein the fourth power is less than the fifth power, and the fifth power is less than the sixth power. According to the above description of the power control of the first UV module and the second UV module, controlling the first UV module and the second UV module to operate at different powers is to control different currents to flow to the first lamp bead and the second lamp bead. Taking the first UV module as an example, in the first sterilization mode, the current flowing to the first lamp bead is a first current, in the second sterilization mode, the current flowing to the first lamp bead is a second current, and in the third sterilization mode, the current flowing to the first lamp bead is a third current. For example, the first current is 300mA, the second current is 600mA, and the third current is 900mA, with the first current, the second current, and the third current increasing in sequence. Obviously, the first UV module and the second UV module can also include more than three operating modes, and can include two, four, five, or more operating modes.

[0078] It should be noted that when the air quality index is less than or equal to the first preset index, it is not necessary to further determine whether the air quality index is greater than the second preset index. Instead, the first ultraviolet module is directly controlled to operate the first sterilization mode, the second sterilization mode or the third sterilization mode based on the number of people and the comparison result of the number of males and the number of females, or only based on the number of people, or only based on the comparison result of the number of males and the number of females, and the second ultraviolet module is controlled to operate the first odor removal mode, the second odor removal mode or the third odor removal mode. However, this will result in the following problems: when the air quality index is high, the operating power of the first ultraviolet module and the second ultraviolet module is low, the sterilization and odor removal efforts are insufficient, resulting in poor air quality in the indoor space; when the air quality index is low, the operating power of the first ultraviolet module and the second ultraviolet module is high, wasting electricity.

[0079] If the air quality index is greater than the second preset index, that is, the air quality index is greater than the second preset index and less than or equal to the first preset index, for example, the air quality index obtained in S100 is 250, the second preset index is 200, and the first preset index is 300. This indicates that the air quality of the outdoor environment is not very good. At this time, based on the number of people and the comparison result of the number of males and females, the first ultraviolet module is controlled to operate in the second sterilization mode or the third sterilization mode, and the second ultraviolet module is controlled to operate in the second deodorization mode or the third deodorization mode. Figure 2 and Figure 3 The following describes possible control methods of the first ultraviolet module and the second ultraviolet module when the air quality index is greater than the second preset index and less than or equal to the first preset index.

[0080] like Figure 2 As shown, in a possible implementation manner, the control method of the present invention further includes:

[0081] S200: Obtain the number of people in the space where the wall-mounted air conditioner is located;

[0082] S201: Determine whether the number of people is greater than a second preset number. If so, execute S202; if not, execute S203;

[0083] S202: Controlling the first UV module to operate in the third sterilization mode and controlling the second UV module to operate in the third odor removal mode;

[0084] S203: Further based on the comparison result of the number of males and the number of females, the first ultraviolet module is controlled to operate in the second sterilization mode or the third sterilization mode, and the second ultraviolet module is controlled to operate in the second deodorization mode or the third deodorization mode.

[0085] In S200 , similar to S102 , the number of people in the indoor space is obtained through the above-mentioned detection module.

[0086] In S201 , based on the number of people acquired in S200 , it is determined whether the number of people is greater than a second preset number of people.

[0087] If the number of people is greater than the second preset number, for example, if the number of people is 4 and the second preset number is 3, it indicates that there are a large number of people in the indoor space. When people enter and exit the indoor space, air from the outdoor space will enter the indoor space, and people will also carry bacteria, viruses, etc. into the indoor space. The body odor emitted by more people will also be heavier. At this time, the air quality index is greater than the second preset index, and the air quality of the outdoor environment is not very good. At this time, the first UV module is controlled to operate in the third sterilization mode and the second UV module is controlled to operate in the third deodorization mode, that is, executing S202. The first UV module and the second UV module are controlled to operate at maximum power to perform sterilization and deodorization with maximum intensity, reducing the impact of the large number of people and the poor outdoor air quality on the air conditions in the indoor space, improving the conditions in the indoor space, and meeting the needs of the user.

[0088] If the number of people is less than or equal to the second preset number, for example, if the number of people is two and the second preset number is three, it indicates that the number of people in the indoor space is relatively small. With fewer people in the indoor space, fewer bacteria, viruses, and body odor will enter the indoor space. However, the air quality in the outdoor environment is not very good. In this case, based on the comparison result of the number of males and females, the first UV module is controlled to operate in the second sterilization mode or the third sterilization mode, and the second UV module is controlled to operate in the second deodorization mode or the third deodorization mode, i.e., S203 is executed. Further controlling the operating modes of the first and second UV modules based on the gender of the person ensures sterilization and deodorization effects that meet user needs while also saving energy.

[0089] Through the above-mentioned control method, when the air quality index is greater than the second preset index, the operation mode of the first ultraviolet module and the second ultraviolet module is controlled based on the comparison results of the number of people and the number of males and females, so that when the air quality of the outdoor environment is not very good, appropriate sterilization and deodorization efforts can be adopted, while ensuring the sterilization and deodorization effects and saving electricity.

[0090] It should be noted that when the number of people is less than or equal to the second preset number of people, the operating mode of the first ultraviolet module and the second ultraviolet module may not be further controlled based on the comparison results of the number of males and the number of females. However, such a control method may have the problem of poor odor removal effect when there are more males and poor sterilization effect when there are more females.

[0091] like Figure 3 As shown, in a possible implementation manner, S203 further includes:

[0092] S300: Obtain the number of males and females;

[0093] S301: Determine whether the number of males is equal to the number of females. If so, execute S302; if not, execute S303;

[0094] S302: Controlling the first UV module to operate in a second sterilization mode and controlling the second UV module to operate in a second odor removal mode;

[0095] S303: further determine whether the number of males is greater than the number of females. If so, execute S304; if not, execute S305;

[0096] S304: Controlling the first UV module to operate in the second sterilization mode and controlling the second UV module to operate in the third odor removal mode;

[0097] S305: Control the first ultraviolet module to operate in the third sterilization mode, and control the second ultraviolet module to operate in the second odor removal mode.

[0098] In S300, the number of males and females in the indoor space is obtained based on the above detection module.

[0099] In S301, based on the number of males and females obtained in S300, a determination is made as to whether the number of males equals the number of females. If the number of males equals the number of females, for example, if both the number of males and the number of females are 1, and since the outdoor air quality is not very good at this time, the first UV module is controlled to operate in the second sterilization mode and the second UV module is controlled to operate in the second deodorization mode, i.e., S302 is executed. Both the first and second UV modules are controlled to operate at medium power to perform sterilization and deodorization, thereby improving indoor air conditions.

[0100] If the number of males is not equal to the number of females, it is further determined whether the number of males is greater than the number of females, that is, S303 is executed.

[0101] If the number of males exceeds the number of females, for example, if there are 2 males and 0 females, the body odor emitted by males is stronger, requiring increased odor removal efforts. Furthermore, the outdoor air quality is not very good. In this case, the first UV module is controlled to operate in the second sterilization mode, and the second UV module is controlled to operate in the third odor removal mode, executing S304. The first UV module is controlled to operate at medium power to sterilize the indoor space, while the second UV module is controlled to operate at maximum power to fully remove odors from the indoor space, thereby improving indoor air conditions.

[0102] If the number of males is less than the number of females, for example, if there are 0 males and 2 females, since women are generally weaker, the fewer bacteria and viruses in their environment, the better. Furthermore, the outdoor air quality is also not very good. In this case, the first UV module is controlled to operate in the third sterilization mode and the second UV module is controlled to operate in the second deodorization mode, i.e., S305 is executed. The first UV module is controlled to operate at maximum power to fully kill bacteria and viruses in the indoor space, while the second UV module is controlled to operate at medium power to remove odors from the indoor space, thereby improving the indoor air quality.

[0103] Through the above-mentioned control method, when the air quality index is greater than the second preset index and the number of people is less than or equal to the second preset number, the operation mode of the first ultraviolet module and the second ultraviolet module is controlled based on the comparison result of the number of males and the number of females, so that when the air quality in the outdoor environment is poor and the number of people is small, appropriate sterilization and deodorization efforts can be adopted, ensuring the sterilization and deodorization effects while saving electricity.

[0104] If the air quality index is less than or equal to the second preset index, for example, the air quality index is 150 and the second preset index is 200. It means that the air quality of the outdoor environment is OK, not very bad. At this time, based on the number of people and the comparison result of the number of males and females, the first UV module is selectively controlled to operate in the first sterilization mode, the second sterilization mode or the third sterilization mode, and the second UV module is selectively controlled to operate in the first deodorization mode, the second deodorization mode or the third deodorization mode. Figures 4 to 6 To illustrate possible control methods of the first ultraviolet module and the second ultraviolet module when the air quality index is less than or equal to the second preset index.

[0105] like Figure 4 As shown, in a possible implementation manner, the control method of the present invention further includes:

[0106] S400: Obtaining the number of people in the space where the wall-mounted air conditioner is located;

[0107] S401: Determine whether the number of people is less than or equal to a third preset number. If so, execute S402; if not, execute S403;

[0108] S402: Control the first UV module and the second UV module to not operate;

[0109] S403: further determining whether the number of people is greater than a fourth preset number, if so, executing S404; if not, executing S405;

[0110] S404: Controlling the first UV module to operate in the third sterilization mode and controlling the second UV module to operate in the third odor removal mode;

[0111] S405: further determining whether the number of people is greater than the fifth preset number, if so, executing S406; if not, executing S407;

[0112] S406: further controlling the first UV module to operate in the second sterilization mode or the third sterilization mode, and controlling the second UV module to operate in the second deodorization mode or the third deodorization mode based on the comparison result of the number of males and the number of females;

[0113] S407: Further based on the comparison result of the number of males and the number of females, the first UV module is controlled to operate in the first sterilization mode or the second sterilization mode, and the second UV module is controlled to operate in the first deodorization mode or the second deodorization mode.

[0114] The third preset number of people is smaller than the fourth preset number of people, and the fifth preset number of people is smaller than the fourth preset number of people and larger than the third preset number of people.

[0115] In S400 , similar to S102 and S200 , the number of people in the space where the wall-mounted air conditioner is located is obtained through the above-mentioned detection module.

[0116] In S401, based on the number of people obtained in S400, it is determined whether the number of people is less than or equal to a third preset number. If the number of people is less than or equal to the third preset number, for example, if the number of people obtained in S400 is 1 and the third preset number is 2, this indicates that the number of people indoors is small and the outdoor air quality is acceptable. In this case, the first and second UV modules are controlled to be inoperative, i.e., S402 is executed. Sterilization and odor removal by the air conditioning device are not required; the current air conditions meet the user's needs and no power consumption is required.

[0117] If the number of people is greater than the third preset number, for example, the number of people obtained in S400 is 3 and the third preset number is 2, then it is further determined whether the number of people is greater than the fourth preset number, i.e., S403 is executed.

[0118] If the number of people exceeds the fourth preset number, for example, the number of people obtained in S400 is 7 and the fourth preset number is 6, this indicates that there are many people in the indoor space. This increase in the number of people can introduce bacteria, viruses, and other substances into the indoor space, and the body odor of each person can also affect the indoor air conditions. In this case, the first UV module is controlled to operate in the third sterilization mode, and the second UV module is controlled to operate in the third odor removal mode, that is, executing S404. Both the first and second UV modules are controlled to operate at maximum power, performing sterilization and odor removal with maximum effectiveness, reducing the impact of a large number of people on air conditions, better improving the indoor air conditions, and meeting user needs.

[0119] If the number of people is less than or equal to the fourth preset number, that is, the number of people is greater than the third preset number and less than or equal to the fourth preset number, for example, the number of people obtained in S400 is 4, the third preset number is 2, and the fourth preset number is 6. In this case, it is further determined whether the number of people is greater than the fifth preset number, that is, S405 is executed.

[0120] If the number of people is greater than the fifth preset number, that is, the number of people is greater than the fifth preset number and less than or equal to the fourth preset number, for example, the number of people obtained in S400 is 4, the fourth preset number is 6, and the fifth preset number is 3. This indicates that there are still a large number of people in the indoor space, and different genders will emit different body odors, which will also have different impacts on the air conditions in the indoor space. At this time, based on the comparison result of the number of males and the number of females, the first UV module is controlled to operate in the second sterilization mode or the third sterilization mode, and the second UV module is controlled to operate in the second deodorization mode or the third deodorization mode, that is, S406 is executed. The first UV module and the second UV module are controlled to operate at relatively high power, so that the indoor space can be better sterilized and deodorized to meet the needs of users.

[0121] If the number of people is less than or equal to the fifth preset number, that is, the number of people is greater than the third preset number and less than or equal to the fifth preset number, for example, the number of people obtained in S400 is 3, the third preset number is 2, and the fifth preset number is 3. This indicates that there are still a lot of people in the indoor space, and different genders will emit different body odors, which will also have different effects on the air conditions in the indoor space. At this time, based on the comparison result of the number of males and the number of females, the first UV module is controlled to operate in the first sterilization mode or the second sterilization mode, and the second UV module is controlled to operate in the first deodorization mode or the second deodorization mode, that is, S407 is executed. The first UV module and the second UV module are controlled to operate at relatively low power, so that the indoor space can be better sterilized and deodorized to meet the needs of users.

[0122] Through the above-mentioned control method, when the air quality index is less than or equal to the second preset index, the operation mode of the first ultraviolet module and the second ultraviolet module is controlled based on the number of people and the comparison results of the number of males and the number of females, so that when the air quality of the outdoor environment is relatively good, appropriate sterilization and deodorization efforts can be adopted, while ensuring the sterilization and deodorization effects and saving electricity.

[0123] It should be noted that when the number of people is less than or equal to the fourth preset number and greater than the third preset number, it is not necessary to further determine whether the number of people is greater than or equal to the fifth preset number, but to directly control the operation mode of the first ultraviolet module and the second ultraviolet module based on the comparison results of the number of males and the number of females. However, such a control method may have the problem of poor sterilization and deodorization effect when the number of people is large, and excessive sterilization and deodorization when the number of people is small.

[0124] like Figure 5 As shown, in a possible implementation manner, S406 further includes:

[0125] S500: Get the number of males and females;

[0126] S501: Determine whether the number of males is equal to the number of females. If so, execute S502; if not, execute S503;

[0127] S502: Controlling the first UV module to operate in a second sterilization mode and controlling the second UV module to operate in a second deodorization mode;

[0128] S503: further determine whether the number of males is greater than the number of females. If so, execute S504; if not, execute S505;

[0129] S504: Controlling the first UV module to operate in the second sterilization mode and controlling the second UV module to operate in the third odor removal mode;

[0130] S505: Control the first UV module to operate in the third sterilization mode, and control the second UV module to operate in the second odor removal mode.

[0131] In S500 , similar to S300 , the number of males and females in the indoor space is obtained based on the above detection module.

[0132] In S501, based on the number of males and females obtained in S500, a determination is made as to whether the number of males equals the number of females. If the number of males equals the number of females, for example, if the number of males and females is 2, then although the outdoor air quality is acceptable, the total number of people indoors is high. Therefore, the first UV module is controlled to operate in the second sterilization mode, and the second UV module is controlled to operate in the second deodorization mode, executing S502. Both the first and second UV modules are controlled to operate at medium power to perform sterilization and deodorization, meeting user needs.

[0133] If the number of males is not equal to the number of females, it is further determined whether the number of males is greater than the number of females, that is, S503 is executed.

[0134] If there are more men than women, for example, 3 men and 1 woman, and men emit stronger body odor, increased odor removal is required. In this case, the first UV module is controlled to operate in the second sterilization mode and the second UV module is controlled to operate in the third odor removal mode, executing S504. The first UV module is controlled to operate at medium power to sterilize the indoor space, while the second UV module is controlled to operate at maximum power to fully remove odors from the indoor space, meeting user needs.

[0135] If the number of males is smaller than the number of females, for example, there is 1 male and 3 females, since women are generally weaker and therefore prefer an environment with fewer bacteria and viruses, the fewer the better. Furthermore, the total number of people is relatively large. In this case, the first UV module is controlled to operate in the third sterilization mode and the second UV module is controlled to operate in the second deodorization mode, i.e., S505 is executed. The first UV module is controlled to operate at maximum power to fully kill bacteria and viruses in the indoor space, while the second UV module is controlled to operate at medium power to remove odors from the indoor space, thus meeting user needs.

[0136] Through the above-mentioned control method, when the air quality index is less than or equal to the second preset index and the number of people is greater than the fifth preset number, the first ultraviolet module and the second ultraviolet module are further controlled to operate at a relatively high power based on the comparison results of the number of males and the number of females, so that when the air quality in the outdoor environment is okay but the number of people is large, appropriate sterilization and deodorization efforts can be adopted to ensure the sterilization and deodorization effects while saving electricity.

[0137] It should be noted that when the number of people is greater than the fifth preset number and less than or equal to the fourth preset number, the operating mode of the first ultraviolet module and the second ultraviolet module may not be further controlled based on the comparison results of the number of males and the number of females. However, such a control method may have the problem of poor odor removal effect when there are more males and poor sterilization effect when there are more females.

[0138] like Figure 6 As shown, in a possible implementation manner, S407 further includes:

[0139] S600: Obtain the number of males and the number of females;

[0140] S601: Determine whether the number of males is equal to the number of females. If so, execute S602; if not, execute S603;

[0141] S602: Controlling the first UV module to operate in a first sterilization mode and controlling the second UV module to operate in a first odor removal mode;

[0142] S603: further determine whether the number of males is greater than the number of females. If so, execute S604; if not, execute S605;

[0143] S604: Controlling the first UV module to operate in a first sterilization mode and controlling the second UV module to operate in a second odor removal mode;

[0144] S605: Control the first UV module to operate in the second sterilization mode, and control the second UV module to operate in the first odor removal mode.

[0145] In S600 , similar to S300 and S500 , the number of males and females in the indoor space is obtained based on the above detection module.

[0146] In S601, based on the number of males and females obtained in S600, a determination is made as to whether the number of males equals the number of females. If the number of males equals the number of females, for example, if the number of males and females is 1, then since the total number of people is relatively small, the first UV module is controlled to operate in the first sterilization mode and the second UV module is controlled to operate in the first deodorization mode, thus executing S602. Controlling both the first and second UV modules to operate at lower power levels for sterilization and deodorization can meet user needs while also saving energy.

[0147] If the number of males is not equal to the number of females, it is further determined whether the number of males is greater than the number of females, that is, S603 is executed.

[0148] If there are more males than females, for example, two males and one female, the males emit a stronger body odor, requiring increased odor removal. In this case, the first UV module is controlled to operate in the first sterilization mode and the second UV module is controlled to operate in the second odor removal mode, executing S604. The first UV module is controlled to operate at a lower power level to sterilize the indoor space, while the second UV module is controlled to operate at a medium power level to fully remove odors from the indoor space, meeting user needs.

[0149] If the number of males is smaller than the number of females, for example, there is one male and two females, since women are generally weaker, the fewer bacteria and viruses in their environment, the better. In this case, the first UV module is controlled to operate in the second sterilization mode, and the second UV module is controlled to operate in the first deodorization mode, that is, S605 is executed. The first UV module is controlled to operate at a medium power to fully kill bacteria and viruses in the indoor space, while the second UV module is controlled to operate at a lower power to remove odors in the indoor space, meeting user needs.

[0150] Through the above-mentioned control method, when the air quality index is less than or equal to the second preset index and the number of people is less than or equal to the fifth preset number, the first ultraviolet module and the second ultraviolet module are further controlled to operate at a relatively low power based on the comparison result of the number of males and the number of females, so that when the air quality in the outdoor environment is good but the number of people is small, appropriate sterilization and deodorization efforts can be adopted, ensuring the sterilization and deodorization effects while saving electricity.

[0151] It should be noted that when the number of people is less than or equal to the fifth preset number and greater than the third preset number, the operating mode of the first ultraviolet module and the second ultraviolet module may not be further controlled based on the comparison results of the number of males and the number of females. However, such a control method may have the problem of poor odor removal effect when there are more males and poor sterilization effect when there are more females.

[0152] In one possible embodiment, the specific values ​​of the third preset number of people, the fourth preset number of people, and the fifth preset number of people are related to the air quality index, and the specific values ​​of the third preset number of people, the fourth preset number of people, and the fifth preset number of people decrease as the air quality index increases. For example, when the air quality index is less than 50, the third preset number of people is 5, the fourth preset number of people is 8, and the fifth preset number of people is 6; when the air quality index is greater than 50 and less than or equal to 100, the third preset number of people is 4, the fourth preset number of people is 7, and the fifth preset number of people is 5; when the air quality index is greater than 100 and less than or equal to 150, the third preset number of people is 3, the fourth preset number of people is 6, and the fifth preset number of people is 4; when the air quality index is greater than 150 and less than or equal to 200, the third preset number of people is 2, the fourth preset number of people is 5, and the fifth preset number of people is 3. Obviously, the specific values ​​of the third preset number of people, the fourth preset number of people, and the fifth preset number of people may not be related to the air quality index, but there may be a problem that the operating power of the first ultraviolet module and the second ultraviolet module is not appropriate.

[0153] It should be noted that the specific parameters such as the air quality index, the first preset index, the second preset index, the first current, the second current, the third current, the number of people, the first preset number of people, the second preset number of people, the third preset number of people, the fourth preset number of people, the fifth preset number of people, the number of males, and the number of females are merely illustrative descriptions and are not restrictive. Without departing from the principles of the present application, those skilled in the art can flexibly select the specific values ​​of the above parameters according to the specific application scenario, as long as the operation of the first UV module and the second UV module is controlled based on the above parameters to ensure the sterilization and deodorization effects.

[0154] In summary, in the preferred technical solution of the present invention, the operating modes of the first and second UV modules are controlled based on the number of people in the space where the wall-mounted air conditioner is located and the range of the air quality index. This allows the operating mode of the air conditioning device to be controlled in real time based on the air quality of the outdoor environment and the number of people in the indoor space, enabling it to achieve different sterilization and deodorization levels based on different actual conditions, thereby better improving the air conditions in the indoor space while also saving electricity. If the air quality index is greater than a first preset index and the number of people is greater than or equal to the first preset number of people, the first UV module is controlled to operate in the third sterilization mode, and the second UV module is controlled to operate in the third deodorization mode. If the air quality index is less than or equal to the first preset index and greater than the second preset index, then when the number of people is greater than the second preset number, the first ultraviolet module is controlled to run the third sterilization mode and the second ultraviolet module is controlled to run the third odor removal mode; when the number of people is less than or equal to the second preset number, when the number of males is equal to the number of females, the first ultraviolet module is controlled to run the second sterilization mode and the second ultraviolet module is controlled to run the second odor removal mode; when the number of males is greater than the number of females, the first ultraviolet module is controlled to run the second sterilization mode and the second ultraviolet module is controlled to run the third odor removal mode; when the number of males is less than the number of females, the first ultraviolet module is controlled to run the third sterilization mode and the second ultraviolet module is controlled to run the second odor removal mode. If the air quality is less than or equal to the second preset index, then when the number of people is less than or equal to the third preset number of people, the first ultraviolet module and the second ultraviolet module are controlled not to operate; when the number of people is greater than the fourth preset number of people, the first ultraviolet module is controlled to operate in the third sterilization mode, and the second ultraviolet module is controlled to operate in the third deodorization mode; when the number of people is greater than the third preset number of people and less than or equal to the fifth preset number of people, based on the number of males and the number of females, the first ultraviolet module is controlled to operate in the first sterilization mode or the second sterilization mode, and the second ultraviolet module is controlled to operate in the first deodorization mode or the second deodorization mode; when the number of people is greater than the fifth preset number of people and less than or equal to the fourth preset number of people, based on the number of males and the number of females, the first ultraviolet module is controlled to operate in the second sterilization mode or the third sterilization mode, and the second ultraviolet module is controlled to operate in the second deodorization mode or the third deodorization mode. Through the above control method, different sterilization and deodorization strengths can be achieved in accordance with the actual air quality and personnel situation, ensuring the sterilization and deodorization effects while saving electricity.

[0155] Although the various steps in the above embodiment are described in the above-mentioned order, those skilled in the art will understand that in order to achieve the effect of this embodiment, different steps do not have to be executed in such an order. They can be executed simultaneously (in parallel) or in a reverse order. These simple changes are within the scope of protection of this application.

[0156] Refer to 7 to Figure 14To illustrate possible implementations of the sterilization device of the present invention.

[0157] like Figures 7 to 9 As shown, the wall-mounted air conditioner includes a housing 1 and an evaporator 13 disposed within the housing 1. The housing 1 has an air inlet 11 and an air outlet 12. Air from the indoor space enters the housing 1 through the air inlet 11, exchanges heat with the evaporator 13, and then returns to the indoor space through the air outlet 12, thereby achieving the purpose of regulating the temperature of the indoor space. The wall-mounted air conditioner is equipped with an air conditioning device 2, which is disposed within the housing 1 near the air inlet 11 and near the right end of the housing 1. In this way, most of the air entering the housing 1 through the air inlet 11 will flow through the air conditioning device 2, thereby better regulating the air conditions in the indoor space through the air conditioning device 2. The air conditioning device 2 of the present invention includes a mounting bracket 21, a photocatalyst component 22 and an ultraviolet unit 23. The photocatalyst component 22 and the ultraviolet unit 23 are arranged on the mounting bracket 21. The air conditioning device 2 can be installed on the air conditioner through the mounting bracket 21. In this way, the air condition of the space where the air conditioner is located can be adjusted by the air conditioning device 2, thereby improving the user experience. The photocatalyst component 22 is configured to remove odors in the air after being activated. The ultraviolet rays emitted by the ultraviolet unit 23 can irradiate the photocatalyst component 22 and activate the photocatalyst component 22. Among them, the photocatalyst component 22 is roughly a plate-like structure. The photocatalyst component 22 can be made of an aluminum plate as a substrate and a photocatalyst such as titanium dioxide is loaded on the substrate. A plurality of ventilation holes 221 as a first ventilation structure are provided on the aluminum plate. The ventilation holes 221 are hexagonal holes. These multiple ventilation holes 221 are arranged along the thickness direction of the photocatalyst component 22 (roughly Figure 8 ) passes through the photocatalyst member 22 so as to allow the air flowing through the air conditioning device 2 to pass through the photocatalyst member 22. In this way, the air flowing through the air conditioning device 2 can be fully in contact with the photocatalyst member 22, so that the odor in the air can be better removed. In this way, on the one hand, the bacteria, viruses, etc. in the interior of the casing 1 and the air flowing through the casing 1 can be removed by the irradiation of ultraviolet rays emitted by the ultraviolet unit 23. On the other hand, the photocatalyst member 22 can be activated by the irradiation of ultraviolet rays emitted by the ultraviolet unit 23. The activated photocatalyst member 22 is in full contact with the air, so that the odor in the air can be effectively removed. Through such a setting method, the odor in the air can be fully removed while the air is being sterilized, so that the air conditions in the space where the wall-mounted air conditioner is located can be better improved, and the user experience can be enhanced.

[0158] It should be noted that the ventilation holes 221 may also be holes of other possible shapes such as circular holes, elliptical holes, triangular holes, rectangular holes, etc. Those skilled in the art may flexibly select them according to the specific application scenario, as long as they can allow air to pass through.

[0159] It should be noted that the photocatalyst component 22 can also be made of an aluminum mesh or honeycomb ceramic as a substrate, and a photocatalyst such as titanium dioxide is loaded on the substrate. Without departing from the principles of the present application, those skilled in the art can flexibly select the specific setting form of the photocatalyst component 22 according to the specific application scenario, as long as the activated photocatalyst component 22 can remove odors in the air and the photocatalyst component 22 is provided with a first ventilation structure that allows air to pass through.

[0160] It is understandable that photocatalyst, also known as photocatalyst, is a general term for semiconductor materials with photocatalytic functions, represented by nano-scale titanium dioxide. It can produce strong oxidizing substances such as hydroxyl free radicals and active oxygen under light irradiation. It has a strong photoredox function, can oxidize and decompose various organic compounds and some inorganic substances, can destroy bacterial cell membranes and solidify viral proteins, can kill bacteria and decompose organic pollutants, and decompose organic pollutants into pollution-free water (H2O) and carbon dioxide (CO2). It has extremely strong sterilization, deodorization, mildew prevention, anti-fouling self-cleaning and air purification functions.

[0161] It should be noted that the air conditioning device 2 can also be set near the left end of the casing 1. Of course, the air conditioning device 2 can also be set at other locations on the wall-mounted air conditioner, for example, at the air inlet 11 or on the inner side of the front panel of the wall-mounted air conditioner, or in the air duct formed between the air inlet 11 and the air outlet 12, etc. Without departing from the principles of the present application, those skilled in the art can flexibly select the specific location of the air conditioning device 2 in the wall-mounted air conditioner according to the specific application scenario, as long as the air conditioning device 2 can sterilize the air and remove odors in the air.

[0162] It should be noted that the length direction of the wall-mounted air conditioner is approximately Figure 7 Left and right direction in .

[0163] like Figures 7 to 9 、 Figures 12 to 14 As shown, the UV unit 23 includes a first UV module 231 and a second UV module 232. The first UV module 231 and the second UV module 232 are both disposed on the same side of the photocatalyst component 22 (ie, Figure 8 The first UV module 231 and the second UV module 232 are arranged along the width direction of the mounting bracket 21 (ie, the right side shown in FIG). Figure 8 Thus, by arranging the first UV module 231 and the second UV module 232 on the same side of the photocatalyst 22, the UV rays emitted by the first UV module 231 and the second UV module 232 are distributed along the length direction of the air conditioner (i.e. Figure 7), the ultraviolet rays emitted by the two ultraviolet modules can irradiate a larger area of ​​the photocatalyst member 22, thereby better activating the photocatalyst member 22 and achieving a better deodorization effect. Moreover, in this case, the ultraviolet rays emitted by the first ultraviolet module 231 and the second ultraviolet module 232 can irradiate a larger area within the housing 1, thereby achieving a better sterilization effect. In addition, arranging the first ultraviolet module 231 and the second ultraviolet module 232 on the same side of the photocatalyst member 22 can also make the overall air conditioning device 2 more regular and beautiful. Through this arrangement, better sterilization and deodorization effects can be achieved.

[0164] It should be noted that according to Figure 8 As shown in the orientation, the above-mentioned arrangement of the first ultraviolet module 231 and the second ultraviolet module 232 on the right side of the photocatalyst component 22 is merely an exemplary description. Obviously, the first ultraviolet module 231 and the second ultraviolet module 232 can also be arranged at other possible positions such as the left side, front side, and rear side of the photocatalyst component 22, as long as the first ultraviolet module 231 and the second ultraviolet module 232 can be arranged on the same side of the photocatalyst component 22. Obviously, the first ultraviolet module 231 and the second ultraviolet module 232 may not be arranged on the same side of the photocatalyst component 22. For example, one of the two ultraviolet modules is arranged on the right side of the photocatalyst component 22, and the other is arranged on the rear side of the photocatalyst component 22. In this case, the ultraviolet rays emitted by the ultraviolet module arranged on the right side of the photocatalyst component 22 are transmitted along the length direction of the air conditioner (i.e. Figure 7 The ultraviolet light emitted by the ultraviolet module arranged at the rear side of the photocatalyst 22 is roughly along the height direction of the air conditioner (roughly Figure 7 ) irradiation. Obviously, the ultraviolet unit 23 may also include only one ultraviolet module. However, in this case, there will be a problem that the ultraviolet unit 23 cannot take into account both the sterilization and deodorization effects. Because the short-wave ultraviolet rays have a stronger sterilization ability and the long-wave ultraviolet rays can better excite the photocatalyst part 22, no matter which band of ultraviolet rays is selected, it will affect the sterilization or deodorization effect of the ultraviolet unit 23. Without departing from the principles of the present application, those skilled in the art can flexibly select the specific setting form of the ultraviolet unit 23 according to the specific application scenario, as long as the ultraviolet rays emitted by the ultraviolet unit 23 can activate the photocatalyst part 22.

[0165] like Figures 12 to 14As shown, the first ultraviolet module 231 includes a first lamp board 2311 and a first lamp bead 2312, and the second ultraviolet module 232 includes a second lamp board 2321 and a second lamp bead 2322. The first lamp bead 2312 is arranged on the first lamp board 2311, and the second lamp bead 2322 is arranged on the second lamp board 2321. The first lamp board 2311 and the second lamp board 2321 are respectively connected to the external power supply through a first electrical conductor (not shown) and a second electrical conductor (not shown). In this way, the first lamp board 2311 and the second lamp board 2321 can be powered by an external power supply, thereby ensuring the stable operation of the first ultraviolet module 231 and the second ultraviolet module 232.

[0166] In another possible embodiment, Figures 12 to 14 As shown, the first ultraviolet module 231 includes a first lamp board 2311 and a first lamp bead 2312, and the second ultraviolet module 232 includes a second lamp board 2321 and a second lamp bead 2322. The first lamp bead 2312 is arranged on the first lamp board 2311, and the second lamp bead 2322 is arranged on the second lamp board 2321. The first lamp board 2311 and the second lamp board 2321 are connected. One of the first lamp board 2311 and the second lamp board 2321 is connected to an external power supply through a third electrical conductor (not shown). In this way, by connecting one of the two lamp boards to an external power supply, power can be supplied to the two lamp boards, thereby ensuring stable operation of the first ultraviolet module 231 and the second ultraviolet module 232.

[0167] Without departing from the principles of the present application, those skilled in the art can flexibly select the specific setting form of the first ultraviolet module 231 and the second ultraviolet module 232 according to the specific application scenario, as long as the ultraviolet rays emitted by the first ultraviolet module 231 and the second ultraviolet module 232 can perform sterilization and activate the photocatalyst component 22.

[0168] In one possible embodiment, the first lamp bead 2312 is a UVC LED lamp bead, and the second lamp bead 2322 is a UVA LED lamp bead. The brightness of the UVC LED lamp bead is relatively weak, and the ultraviolet rays emitted are short-wave ultraviolet rays with a wavelength of 190 to 280 nm. The ultraviolet rays in this wavelength band cannot fully activate the photocatalyst component 22, but they have strong penetration and a good sterilization effect. The brightness of the UVA LED lamp bead is relatively strong, and the ultraviolet rays emitted are long-wave ultraviolet rays with a wavelength of 320 to 420 nm. The ultraviolet rays in this wavelength band can fully activate the photocatalyst component 22, but their penetration is relatively poor and the sterilization effect is average. In this way, by using UVC LED lamp beads in conjunction with UVA LED lamp beads, it is possible to take into account both sterilization and deodorization, obtain better sterilization and deodorization effects, and better improve the air conditions in the indoor space.

[0169] It should be noted that the first lamp bead 2312 and the second lamp bead 2322 can also be configured as UVC LED lamp beads or UVA LED lamp beads. Obviously, the first lamp bead 2312 and / or the second lamp bead 2322 can also be configured as UVB LED lamp beads. Without departing from the principles of the present application, those skilled in the art can flexibly select the specific configuration of the first lamp bead 2312 and the second lamp bead 2322 according to the specific application scenario, as long as they can achieve good sterilization and deodorization effects.

[0170] like Figures 7 to 11 、 Figure 13 and Figure 14 As shown, the UV unit 23 further includes a cover 233, which is generally an inverted cover-shaped structure. The cover 233 has two sides along the length direction of the mounting bracket 21 (approximately Figure 8 A second clip 2331 extends downward from the side of the front and rear sides (shown in the figure). Two clip holes 211 are correspondingly provided on the mounting bracket 21, and the two second clips 2331 are respectively engaged with the two clip holes 211, thereby setting the cover 233 on the mounting bracket 21. The first ultraviolet module 231 and the second ultraviolet module 232 are arranged in the cover 233, and the cover 233 is provided with a first light-transmitting hole 2332 and a second light-transmitting hole 2333. In the assembled state, the cover 233 covers the first lamp board 2311 and the second lamp board 2321, and the first lamp bead 2312 and the second lamp bead 2322 pass through the first light-transmitting hole 2332 and the second light-transmitting hole 2333 respectively. In this way, when the first lamp bead 2312 and the second lamp bead 2322 are energized, the ultraviolet rays emitted by the first lamp bead 2312 and the second lamp bead 2322 can be emitted outward along the length direction of the wall-mounted air conditioner (i.e. Figure 7 The first and second light-transmitting holes 2332 and 2333 gradually increase in radial dimension along the direction of illumination of the first and second lamp beads 2312 and 2322, so that the first and second light-transmitting holes 2332 and 2333 form a trapezoidal hole with a trapezoidal interface. This expands the angle of illumination of the ultraviolet rays emitted by the first and second lamp beads 2312 and 2322, increasing the range of illumination. With this arrangement, the ultraviolet rays emitted by the first and second lamp beads 2312 and 2322 can illuminate a larger area of ​​the photocatalyst component 22, better activating the photocatalyst component 22 and achieving a better deodorizing effect. At the same time, they can also illuminate a larger area within the wall-mounted air conditioner along the length of the wall-mounted air conditioner, achieving a better sterilization effect.

[0171] It should be noted that the cover 233 can also be set on the mounting bracket 21 by other possible means such as screwing or bonding. Obviously, a separate housing can also be provided for the first UV module 231 and the second UV module 232, and the two housings are respectively provided on the outside of the first UV module 231 and the second UV module 232. Of course, the UV unit 23 may also not include the cover 233. Without departing from the principles of the present application, those skilled in the art can flexibly select the specific configuration of the cover 233 according to the specific application scenario, as long as it can ensure the stable operation of the air conditioning device 2.

[0172] It should be noted that the length direction of the mounting bracket 21 is approximately Figure 7 The left and right direction in the diagram is roughly consistent with the length direction of the air conditioner.

[0173] like Figures 8 to 14 As shown and in accordance with Figure 8 In the illustrated position, the mounting bracket 21 is a generally plate-like structure, provided with a through-hole 212 serving as a second ventilation structure. The through-hole 212 is generally rectangular and extends through the mounting bracket 21 along its thickness. The through-hole 212 is slightly smaller than the photocatalyst 22. When the photocatalyst 22 is mounted on the mounting bracket 21, the plurality of ventilation holes 221 align with the through-hole 212. This allows air flowing through the air conditioning device 2 to pass from the upper side of the photocatalyst 22 to the lower side, through the photocatalyst 22, and then out through the through-hole 212. This prolongs the contact time between the air and the photocatalyst 22, increases the contact area between the air and the photocatalyst 22, and ensures more complete contact between the air and the photocatalyst 22, thereby effectively removing odors from the air. Furthermore, the air flow direction is substantially perpendicular to the direction of the ultraviolet rays emitted by the first ultraviolet module 231 and the second ultraviolet module 232. Thus, the ultraviolet rays emitted by the two ultraviolet modules can better irradiate the air and remove bacteria, viruses, etc. in the air. It should be noted that only some of the ventilation holes 221 may be aligned with the through holes 212.

[0174] It should be noted that the through hole 212 can also be set to other possible shapes such as circular, elliptical, square, polygonal, and irregular. Obviously, the second ventilation structure can also be formed by a plurality of hole arrays, and the shapes of these holes can be, but are not limited to, rectangular, circular, elliptical, square, polygonal, and irregular shapes. Without departing from the principles of this application, those skilled in the art can flexibly select the specific setting form of the second ventilation structure according to the specific application scenario, as long as it can allow air to pass through,

[0175] like Figures 8 to 14 As shown and in accordance with Figure 9In the orientation shown, the mounting bracket 21 is provided with a recessed area 213, which is arranged along the circumference of the through hole 212. The mounting bracket 21 is also provided with three first clips 214, which are divided into two groups, one group including two first clips 214 and the other group including one first clip 214. The two groups of clips are respectively provided on the upper side and the lower side of the recessed area 213. The two first clips 214 located on the upper side of the recessed area 213 are arranged along the length direction of the upper side of the recessed area 213 (i.e. Figure 9 The photocatalyst 22 is arranged in the left-right direction (shown in FIG). A first latch 214 located on the lower side of the recessed area 213 is approximately located in the middle of the lower side of the recessed area 213. A latching position is formed between the three first latches 214 and the recessed area 213, and the photocatalyst 22 can be latched in this latching position. When the photocatalyst 22 is installed, the lower portion of the photocatalyst 22 is located within the recessed area 213. This arrangement allows the photocatalyst 22 to be better secured to the mounting bracket 21. Obviously, the mounting bracket 21 does not need to be provided with a recessed area 213.

[0176] It should be noted that the number and distribution of the first clips 214 described above are merely exemplary and not restrictive. Clearly, two, four, five, or even more first clips 214 may be provided on the mounting bracket 21. Without departing from the principles of the present application, those skilled in the art may flexibly select the number and arrangement of the first clips 214 based on specific application scenarios, as long as a securing position for securing the photocatalyst component 22 is formed between the first clips 214 and the mounting bracket 21.

[0177] Obviously, the photocatalyst 22 can also be mounted on the mounting bracket 21 by screwing, bonding, or other possible methods.

[0178] like Figures 7 to 10 、 Figure 12 and Figure 14 As shown and in accordance with Figure 8In the orientation shown, the UV unit 23 also includes a mounting plate 234. The mounting plate 234 is generally L-shaped and includes a vertical portion 2341 and a horizontal portion 2342. The horizontal portion 2342 is provided with two first mounting holes 23421. Two second mounting holes 215 are provided at corresponding positions on the mounting bracket 21 as mounting structures. Fasteners (such as screws, bolts, etc.) are sequentially passed through the first mounting holes 23421 and the second mounting holes 215 and connected to the tube sheet of the evaporator 13. In this way, the mounting plate 234 can be set on the mounting bracket 21, and the mounting bracket 21 can be set on the evaporator 13. The evaporator 13 of the present application is a fin-type evaporator 13. The mounting bracket 21 extends toward the evaporator 13 with an insert 216 as a positioning member. The insert 216 is generally wide at the top and narrow at the bottom. In the assembled state, the insert 216 is inserted between the two fins of the evaporator 13 to prevent the mounting bracket 21 from shaking. Thus, the mounting bracket 21 can be fixed to the evaporator 13 via the insert 216 and the mounting structure. In the assembled state, at least a portion of the ultraviolet light emitted by the first and second lamp beads 2312, 2322 will illuminate the surface of the evaporator 13, thereby removing bacteria, viruses, and other substances from the surface of the evaporator 13. Air entering the housing 1 through the air inlet 11 will first exchange heat with the evaporator 13 before returning to the indoor space. In other words, the air in the housing 1 will flow over the surface of the evaporator 13, thereby effectively removing bacteria, viruses, and other substances from the air in the housing 1.

[0179] It should be noted that the mounting structure may also be in other possible forms such as claws, magnetic adsorption parts, adhesive layers, etc., that is, the mounting bracket 21 may also be set on the tube plate of the evaporator 13 by means of clamping, magnetic adsorption, bonding, etc.

[0180] like Figures 8 to 10 、 Figure 12 and Figure 14 As shown and in accordance with Figure 8 In the orientation shown, the first lamp board 2311 and the second lamp board 2321 are disposed on the left side of the vertical portion 2341. After the cover 233 is assembled with the mounting bracket 21, the inner wall of the top plate of the cover 233 mates with the top end of the vertical portion 2341, thereby placing the first lamp board 2311 and the second lamp board 2321 on the mounting bracket 21 and within the cover 233. When assembled, a gap exists between the cover 233 and the two ends of the vertical portion 2341 along the width direction of the mounting bracket 21. In this way, heat generated by the first lamp board 2311 and the second lamp board 2321 during operation can be dissipated to the environment through the gap, thereby ensuring stable operation of the UV unit 23.

[0181] It should be noted that the UV unit 23 may not include the mounting plate 234. The first lamp board 2311 and the second lamp board 2321 may be arranged on the mounting bracket 21 in other ways. For example, two card block groups are provided on the mounting bracket 21. Each card block group includes two oppositely arranged card blocks with a gap between the two card blocks. The two card block groups are arranged along the width direction of the mounting bracket 21 (approximately Figure 8 The first light board 2311 and the second light board 2321 are respectively clamped in the gap between the two clamping block groups, so that the first light board 2311 and the second light board 2321 are clamped on the mounting bracket 21. Obviously, the first light board 2311 and the second light board 2321 can also be set on the mounting bracket 21 by screwing, bonding, etc. Without departing from the principles of the present application, those skilled in the art can flexibly select the fixing method of the first light board 2311 and the second light board 2321 on the mounting bracket 21 according to the specific application scenario, as long as the first light board 2311 and the second light board 2321 can be fixed on the mounting bracket 21.

[0182] like Figures 8 to 10 、 Figure 12 and Figure 14 As shown and in accordance with Figure 8 In the orientation shown, three reinforcing ribs 23411 are provided on the right side of the vertical portion 2341. The three reinforcing ribs 23411 are substantially along the width direction of the mounting plate 234 (approximately Figure 8 The mounting plate 234 is provided with a long strip-shaped structure extending in a direction perpendicular to the paper (in the figure). The reinforcing ribs 23411 can enhance the strength of the mounting plate 234. Obviously, those skilled in the art can flexibly adjust the number, extension direction, and specific shape of the reinforcing ribs 23411, as long as the strength of the mounting plate 234 is enhanced. For example, the mounting plate 234 may be provided with four reinforcing ribs 23411, two of which extend along the length of the mounting plate 234, and the other two reinforcing ribs 23411 are arranged perpendicular to and intersect with the aforementioned two reinforcing ribs 23411, etc.

[0183] In summary, in the preferred technical solution of the present invention, the photocatalyst member 22 is irradiated and activated by the ultraviolet rays emitted by the ultraviolet unit 23, and a first ventilation structure is provided on the photocatalyst member 22, so that the air can be more fully in contact with the activated photocatalyst member 22, thereby better removing odors from the air. At the same time, the ultraviolet rays emitted by the ultraviolet unit 23 can also sterilize the air, thereby effectively removing odors from the air while sterilizing the air, and better improving the air conditions in the indoor space. The ultraviolet unit 23 includes a first ultraviolet module 231 and a second ultraviolet module 232, and the first ultraviolet module 231 and the second ultraviolet module 232 are arranged on the same side of the photocatalyst member 22, so that the ultraviolet rays emitted by the first ultraviolet module 231 and the second ultraviolet module 232 are irradiated in the same direction, thereby achieving better sterilization and deodorization effects. By configuring the first lamp 2312 of the first UV module 231 as a UVC LED lamp and the second lamp 2322 of the second UV module 232 as a UVA LED lamp, both sterilization and deodorization effects are achieved. By disposing the first and second UV modules 231, 232 within the housing 233, with the first and second lamps 2312, 2322 respectively passing through first and second light-transmitting holes 2332, 2333 provided in the housing 233, and with the radial dimensions of the first and second light-transmitting holes 2332, 2333 gradually increasing along the direction of ultraviolet light emitted by the first and second lamps 2312, 2322, better deodorization and sterilization effects are achieved. By providing a second ventilation structure on the mounting bracket 21, with at least a portion of the first ventilation structure aligned with the second ventilation structure when installed, air is better contacted with the photocatalyst element 22, achieving a better deodorization effect.

[0184] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-functional manner to combine new implementations to suit more specific application scenarios.
