Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioners, and particularly relates to an air conditioner. Background Art

[0002] Due to its strong oxidizing property, hydroxyl radicals are widely used in the fields of water treatment, air purification, degradation of organic pollutants, surface modification of materials, etc. In the field of air purification, an air conditioner is provided with a hydroxyl generator inside its housing to generate hydroxyl radicals.

[0003] In related technologies, the generation mechanism of the hydroxyl generator is to collect moisture first, and then ionize the collected moisture by using direct current high voltage to generate hydroxyls. Exemplarily, a semiconductor refrigeration sheet connected to the bottom of a metal needle-shaped emission electrode operates to cool the emission electrode. When the temperature is lower than the dew point temperature, condensed water will form on the electrode. After connecting high-voltage direct current electricity, a strong electric field is formed around the emission electrode, and the moisture attached to the emission electrode is ionized to form hydroxyl radicals. However, the number of hydroxyl radicals generated in this way is relatively small, and the energy consumption is large, resulting in a high cost.

[0004] In view of this, the present application is proposed. Summary of the Invention

[0005] In the hydroxyl generator of the present application, a discharge electrode and a water absorption component are arranged along the air flow direction. First, the discharge electrode is used to ionize oxygen to generate oxygen ions, and the oxygen ions and water generate hydroxyl radicals. The air flow enters the housing through the return air inlet and carries the oxygen ions generated by the ionization of the discharge electrode and flows out of the housing through the air supply outlet, realizing the long-distance and large-range diffusion of hydroxyl radicals and improving the purification effect.

[0006] An embodiment of the present application provides an air conditioner, which includes:

[0007] An indoor housing, which is used to form the external contour of the indoor unit, and the indoor housing is formed with an indoor air inlet and an indoor air outlet;

[0008] An indoor heat exchanger, which is arranged inside the indoor housing. Indoor air enters the indoor housing through the indoor air inlet, exchanges heat with the indoor heat exchanger, and then flows out of the indoor housing through the indoor air outlet;

[0009] A hydroxyl generation device, which is arranged on the indoor heat exchanger. The hydroxyl generation device further includes:

[0010] A housing, on which a return air inlet and an air supply outlet are formed;

[0011] An internal air duct, which is formed inside the external part. The internal air duct is communicated with the return air inlet and the air supply outlet;

[0012] A drive power supply, which is arranged inside the housing and is used to provide power;

[0013] A discharge electrode, which is arranged inside the internal air duct, and the discharge electrode is connected to a driving electrode to ionize oxygen to generate oxygen ions;

[0014] An internal fan, which is arranged inside the internal air duct, and the internal fan is driven to let air flow into the internal air duct from the air return opening, carry oxygen ions and flow out of the housing through the air supply opening;

[0015] A water absorption component, which is arranged near the air supply opening, and the moisture of the water absorption component reacts with the oxygen ions flowing through the air supply opening to generate hydroxyl radicals;

[0016] The indoor air enters the internal air duct through the air return opening, flows through the discharge electrode and the water absorption component, then carries the generated hydroxyl radicals and flows out of the internal air duct along the air supply opening, and diffuses along the length direction of the indoor heat exchanger.

[0017] The indoor air first enters the housing through the air return opening, and then flows through the discharge electrode. The discharge electrode ionizes to generate oxygen ions. Then, the air carrying oxygen ions flows through the water absorption component, and the moisture combines with the oxygen ions to generate hydroxyl radicals. The generated hydroxyl radicals then diffuse along the length direction of the indoor heat exchanger, purify the air flowing through the heat exchanger, effectively remove pollutants such as particulate matter, bacteria and viruses in the air, and improve the indoor air quality.

[0018] In some embodiments, the hydroxyl radical generating device further includes a diversion platform, which is arranged inside the internal air duct. The diversion platform is arranged opposite to the air return opening. The air flow blows towards the diversion platform after flowing through the air return opening, and carries oxygen ions through the air supply opening and flows out of the housing when flowing through the discharge electrode.

[0019] When the indoor air enters the internal air duct through the air return opening, it will first blow towards the diversion platform. During this process, the air flow velocity increases, and at the same time, it carries the oxygen ions generated by the discharge electrode. These oxygen ions are decomposed into oxygen ions due to the ionization effect when flowing through the discharge electrode. Subsequently, the fast air flow carrying oxygen ions passes through the internal air duct and finally flows out of the housing through the air supply opening. This process not only improves the carrying efficiency of oxygen ions, but also ensures that the air has fully contacted the discharge electrode before flowing out of the housing, thereby enhancing the air purification effect.

[0020] Through the design and layout of the diversion platform, the hydroxyl radical generating device can introduce oxygen ions into the indoor air more efficiently, thus playing an important role in the air purification process.

[0021] At the same time, the diversion platform is thicker than other positions of the internal air duct, which directly results in less influence by the external temperature difference, thereby reducing the risk of condensation.

[0022] In some embodiments, the hydroxyl radical generating device further includes a first mounting seat, which is arranged on the inner side wall of the housing. The first mounting seat is used to mount the discharge electrode so that there is a certain gap between the discharge electrode and the inner side wall of the housing.

[0023] By providing the first mounting seat, the discharge electrode can be accurately positioned and installed, while maintaining an appropriate distance from the inner wall of the housing, thus ensuring the efficient operation and safe operation of the device.

[0024] In some embodiments, the hydroxyl generating device includes a plurality of drain holes provided on the housing for draining the condensed water inside the housing. Its main function is to effectively drain the condensed water generated inside the housing.

[0025] In some embodiments, the hydroxyl generating device further includes a flow guiding member provided at the air supply opening and located outside the housing. The airflow at the air supply opening diffuses along the end face of the flow guiding member. When there is airflow passing through the air supply opening, the airflow will diffuse along the end face of the flow guiding member, thereby achieving a specific airflow distribution effect. It can also expand the diffusion range.

[0026] In some embodiments, the air conditioner includes an electric control box provided on one side of the indoor housing; it also includes an external power supply provided inside the electric control box. The external power supply is connected to the drive power supply and the internal blower. The external power supply is respectively connected to the drive power supply and the internal blower to provide them with the required power support to ensure the normal operation of the air conditioner.

[0027] Such a design and configuration enable the hydroxyl generating device and the air conditioner to more efficiently and stably perform their respective functions, bringing a better user experience to the users.

[0028] In some embodiments, the housing includes a first housing and a second housing. The first housing is installed on the indoor heat exchanger, and the second housing is detachably connected to the first housing. The second housing is provided with a return air opening and an air supply opening.

[0029] The first housing is firmly installed on the indoor heat exchanger to serve as the support and protection for the entire housing.

[0030] The second housing is designed to be detachably connected to the first housing, which is convenient for maintenance and replacement. The second housing is particularly provided with a return air opening and an air supply opening. These air openings are important components in the air conditioning system, responsible for sucking in the indoor air and then sending it out after being processed to achieve the circulation and adjustment of the indoor air.

[0031] In some embodiments, the hydroxyl generating device includes a second mounting seat provided on the first housing, and the housing is installed on the indoor heat exchanger through the second mounting seat.

[0032] This mounting seat is accurately set at an appropriate position on the first housing. Through this second mounting seat, the housing can be stably installed on the indoor heat exchanger to ensure the stability and safety of the entire system.

[0033] In some embodiments, the water absorption components are provided as at least two, and the water absorption components are arranged at intervals.

[0034] This arrangement at intervals helps to improve the reaction efficiency and ensure that water can participate in the reaction process evenly. Such a design not only improves the working efficiency of the device but also enhances the reliability and durability of the system.

[0035] An embodiment of the present application also provides an air conditioner, which includes:

[0036] An indoor housing, which is used to form the external contour of the indoor unit, and the indoor housing is formed with an indoor air inlet and an indoor air outlet;

[0037] An indoor heat exchanger, which is arranged inside the indoor housing. Indoor air enters the indoor housing through the indoor air inlet, exchanges heat with the indoor heat exchanger, and then flows out of the indoor housing through the indoor air outlet;

[0038] A hydroxyl generating device, which is arranged on the indoor heat exchanger. The hydroxyl generating device further includes:

[0039] A housing, on which an air return opening and an air supply opening are formed;

[0040] An internal air duct, which is formed inside the housing. The internal air duct is communicated with the air return opening and the air supply opening;

[0041] A guide platform, which is arranged inside the internal air duct. The guide platform is arranged opposite to the air return opening, and the guide platform forms an arc surface along the internal air duct;

[0042] The distance between the guide end surface of the guide platform and the end surface of the housing away from the air return opening decreases from the side away from the air supply opening to the side close to the air supply opening.

[0043] In the above embodiments, the internal air duct is used to connect the air return opening and the air supply opening to form a channel for air circulation. The guide platform is arranged inside the internal air duct and corresponds to the air return opening. The guide platform forms an arc surface along the internal air duct, and the design of this arc surface is intended to guide the flow direction of air.

[0044] The distance between the guide end surface of the guide platform and the end surface of the housing away from the air return opening gradually decreases from the side away from the air supply opening to the side close to the air supply opening. The purpose of this design is to increase the flow velocity of air inside the internal air duct, reduce the influence of the external temperature on the temperature of the air flow inside the internal air duct, and reduce the risk of condensation.

[0071] An embodiment of the present application provides an air conditioner 100. Refer to Figure 1 , the air conditioner 100 includes an indoor unit.

[0072] The air conditioner 100 further includes an outdoor unit.

[0073] The outdoor unit is installed outdoors. The indoor unit and the outdoor unit are connected by pipelines for the refrigerant to flow.

[0074] The indoor unit includes an indoor housing 1. The indoor housing 1 is used to form the outer contour of the indoor unit and accommodate the internal components of the indoor unit.

[0075] An indoor air inlet 2 is formed on the indoor housing 1. The indoor air inlet 2 is used for indoor air to enter the indoor housing 1. An air inlet grille is provided at the indoor air inlet 2 for filtering air to prevent larger impurities from entering the heat exchange air duct 5.

[0076] An indoor air outlet 3 is formed on the indoor housing 1. The indoor air outlet 3 is used for the air inside the indoor housing 1 to be discharged. The indoor air enters the indoor housing 1 through the indoor air inlet 2 and then blows out from the indoor air outlet 3.

[0077] The indoor air outlet 3 can be arranged to extend along the length direction of the indoor unit, improving the aesthetics of the indoor unit of the air conditioner 100 and making the overall integrity of the indoor unit of the air conditioner 100 better. Of course, in other embodiments of the present application, the positions of the indoor air inlet 2 and the indoor air outlet 3 can also be set at other positions as long as the air inlet and outlet requirements can be met.

[0078] A wind deflector 4 is provided at the indoor air outlet 3. The wind deflector 4 is movably arranged at the indoor air outlet 3 for opening and closing the indoor air outlet 3. When the wind deflector 4 opens the indoor air outlet 3, the wind deflector 4 can also be configured to direct the heat-exchanged air discharged from the indoor unit through the indoor air outlet 3.

[0079] A plurality of components constituting a refrigeration cycle or a heating cycle are installed inside the indoor housing 1.

[0080] In this application, the indoor unit includes but is not limited to a wall-mounted air conditioner 100, a cabinet air conditioner 100, and a duct machine.

[0081] In the embodiments of the present application, the wall-mounted air conditioner 100 is taken as an example for illustration. Other types of air conditioners 100 can adjust the installation position of the hydroxyl generating device 9 on the basis of the technical solutions of the embodiments of the present application.

[0082] In some embodiments, the indoor housing 1 is generally rectangular in shape.

[0083] It should be noted that the directions described in the text are based on the direction in which the user faces the indoor unit of the air conditioner 100. Among them, the side facing the user when the indoor unit of the air conditioner 100 is in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished according to the direction in which the user faces the indoor unit of the air conditioner 100. The upper and lower sides are distinguished by defining the upper and lower sides when the indoor unit of the air conditioner 100 is generally operating normally.

[0084] The indoor unit includes an indoor heat exchanger 7. The indoor heat exchanger 7 is installed in the indoor housing 1. The indoor heat exchanger 7 is used to exchange heat with the air flow entering the indoor housing 1. The indoor air enters the indoor housing 1 through the indoor air inlet 2, exchanges heat with the indoor heat exchanger 7, and then flows out of the indoor housing 1 through the indoor air outlet 3.

[0085] The indoor unit includes an indoor fan 8. The indoor fan 8 is installed in the indoor housing 1. The indoor fan 8 rotates to make the indoor air enter the indoor housing 1, and the indoor air exchanges heat with the indoor heat exchanger 7 and then flows out of the indoor housing 1.

[0086] In some embodiments, the indoor fan 8 is set as a cross-flow fan. The indoor heat exchanger 7 is annularly arranged above the indoor fan 8.

[0087] In some embodiments, the indoor unit includes a heat exchange air duct 5. The heat exchange air duct 5 is used to provide a channel for the air flow to circulate. The indoor heat exchanger 7 and the indoor fan 8 are arranged in the heat exchange air duct 5.

[0088] In some embodiments, the air conditioner 100 system in the present application includes a compressor. The compressor can compress the gaseous refrigerant in a high-temperature and high-pressure state and discharge the compressed gaseous refrigerant.

[0089] The compressor includes a suction port. The refrigerant flows into the compressor from the suction port to be compressed.

[0090] The compressor includes an exhaust port. The refrigerant enters the compressor from the suction port, is compressed by the compressor, and then is discharged from the exhaust port.

[0091] The air conditioner 100 system includes an indoor heat exchanger 7 for heat exchange with indoor air.

[0092] The air conditioner 100 system includes an outdoor heat exchanger for heat exchange with outdoor air.

[0093] The air conditioner 100 system further includes a four-way valve. The first port of the four-way valve is connected to the exhaust port of the compressor. The second port of the four-way valve is connected to the suction port of the compressor. The third port of the four-way valve is connected to the indoor heat exchanger 7. The fourth port of the four-way valve is connected to the outdoor heat exchanger.

[0094] The air conditioner 100 system further includes an electronic expansion valve. The electronic expansion valve is arranged between the outdoor heat exchanger and the indoor heat exchanger 7. The electronic expansion valve is used for throttling. The electronic expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0095] The indoor heat exchanger 7 and the outdoor heat exchanger are used as condensers or evaporators. When the indoor heat exchanger 7 is used as a condenser, the air conditioner 100 is used as a heater in the heating mode. When the indoor heat exchanger 7 is used as an evaporator, the air conditioner 100 is used as a cooler in the cooling mode.

[0096] The multi-connected air conditioner 100 blows air-conditioning air that is higher than the indoor temperature, lower than the indoor temperature, or the same as the indoor temperature by means of refrigerant flow to adjust the temperature and humidity of the indoor environment; or adjusts the air flow rate of the indoor environment by means of the rotation speed of the indoor fan 8.

[0097] When the air conditioner 100 operates in the cooling mode, the refrigerant from the compressor condenses through the outdoor heat exchanger. And the condensed refrigerant flows through the electronic expansion valve for expansion. The expanded condensate evaporates through the indoor heat exchanger 7. Then the evaporated refrigerant circulates back to the compressor.

[0098] When the air conditioner 100 operates in the heating mode, the refrigerant from the compressor condenses through the indoor heat exchanger 7, and the condensed refrigerant expands by flowing through the electronic expansion valve. The expanded condensate evaporates through the outdoor heat exchanger. Then the evaporated refrigerant circulates back to the compressor.

[0099] In some embodiments, referring to Figures 2 - 4 , the air conditioner 100 further includes a hydroxyl generating device 9. The hydroxyl generating device 9 is installed on the indoor heat exchanger 7.

[0100] In some embodiments, the hydroxyl generating device 9 is installed in the heat exchange air duct 5. The hydroxyl radicals generated in the hydroxyl generating device 9 can diffuse along with the air flow to the entire heat exchange air duct 5. It can effectively decompose harmful substances in the air, such as bacteria, viruses, formaldehyde, etc., thereby improving the air cleanliness.

[0101] Referring to Figures 3 - 4 , the hydroxyl generating device 9 is installed on the front side of the indoor heat exchanger 7. Installing the hydroxyl generating device 9 on the front side facilitates the installation and maintenance of the hydroxyl generating device 9.

[0102] In some embodiments, the hydroxyl generating device 9 is installed in the heat exchange air duct 5. In some embodiments, the hydroxyl generating device 9 is installed at the upper right position of the indoor heat exchanger 7. Because this position is relatively close to the electric control box, it is convenient to connect the power cord.

[0103] Meanwhile, referring to Figures 6 - 7 , it is convenient to screw on the edge tube plate 912 of the indoor heat exchanger 7, which is suitable for module installation. The edge tube plate 912 and the second mounting seat 911 are connected by screws.

[0104] In some embodiments, referring to Figure 8 , the hydroxyl generating device 9 includes a housing 91. The housing 91 forms the external contour of the hydroxyl generating device 9, and a cavity is formed inside the housing 91 to provide physical protection and support for the internal components and ensure the stable operation of the internal components.

[0105] Referring to Figure 8, an air return opening 913 and an air supply opening 914 are formed on the housing. The air return opening 913 is used to suck in external air, and the air supply opening 914 is used to send out the processed air, forming a continuous air circulation.

[0106] In some embodiments, the hydroxyl generating device 9 includes an internal air duct 92. It is formed inside the exterior, and the internal air duct 92 communicates with the air return opening 913 and the air supply opening 914, constituting a path for air circulation. The design of the internal air duct 92 helps with the uniform distribution and effective flow of air.

[0107] In some embodiments, referring to Figures 9 - 10 , the hydroxyl generating device 9 includes a driving power source 93, which is arranged inside the housing 91 and is used to supply power to the entire hydroxyl generating device 9. Ensure that each component can work properly.

[0108] In some embodiments, the driving power source 93 can be connected to the power cord inside the electric control box to provide voltage for the driving power source 93. Facilitate the standardization of the overall wiring layout of the air conditioner 100.

[0109] In some embodiments, referring to 11-12, the hydroxyl generating device 9 includes a discharge electrode 94, which is arranged inside the internal air duct 92. The discharge electrode 94 is connected to the driving electrode to ionize oxygen to generate oxygen ions. The discharge electrode 94 generates oxygen ions by ionizing oxygen. The use of the discharge electrode 94 is based on the corona discharge principle, and oxygen molecules are decomposed into oxygen ions through a high-voltage electric field to provide raw materials for generating hydroxyl radicals.

[0110] In some embodiments, referring to Figures 10 - 12 , the hydroxyl generating device 9 includes an internal fan 95, and the internal fan 95 is installed inside the internal air duct 92. The internal fan 95 is driven to allow air to flow from the air return opening 913 into the internal air duct 92, carrying oxygen ions and flowing out of the housing 91 through the air supply opening 914. The use of the internal fan 95 ensures the effective circulation of air and the sufficient distribution of oxygen ions.

[0111] In some embodiments, referring to Figures 10 - 12 , the hydroxyl generating device 9 includes a water absorption component 96, and the water absorption component 96 is installed near the air supply opening 914. The moisture of the water absorption component 96 reacts with the oxygen ions flowing through the air supply opening 914 to generate hydroxyl radicals. Through the moisture (usually water mist or water vapor) in contact with the oxygen ions, hydroxyl radicals are generated. This process is based on the chemical reaction for generating hydroxyl radicals, that is, water molecules react with oxygen ions to generate hydroxyl radicals (·OH).

[0112] It should be noted that the above-mentioned water absorption component 96 being installed near the air supply opening 914 means that the water absorption component 96 is installed through the air supply opening 914 and partially protrudes from the surface of the housing 91.

[0113] In some embodiments, the water absorbing component 96 is disposed at the outlet end of the discharge electrode 94 in the airflow direction so that the oxygen ions can flow with the airflow, and the oxygen ions and the water in the water absorbing component 96 generate hydroxyl radicals.

[0114] In some embodiments, reference Figure 10 , the internal fan 95 is set as an axial flow fan. Under the action of the axial flow fan, the airflow enters the internal air duct 92 of the hydroxyl generator 9, and the discharge electrode 94 located in the internal air duct 92 ionizes the passing air to generate oxygen ions. Under the action of the airflow, the oxygen ions react with the water in the water absorbing component 96 to generate hydroxyl free radicals, which are then diffused to the outside of the hydroxyl generator 9 with the airflow.

[0115] In some embodiments, the water absorbing component 96 is configured as a water absorbing carbon rod. The water absorbing carbon rod absorbs water, which can react with oxygen ions flowing through the water absorbing carbon rod to generate hydroxyl radicals.

[0116] When external air enters the hydroxyl generator 9 through the return air port 913, the discharge electrode 94 ionizes oxygen into oxygen ions by connecting a voltage. Subsequently, the airflow, driven by the internal fan 95, passes through the internal air duct 92, carrying the oxygen ions and moves toward the air supply port 914.

[0117] At the air supply port 914, the water in the water absorbing member 96 contacts with the oxygen ions, and a chemical reaction occurs to generate hydroxyl radicals. These hydroxyl radicals have extremely strong oxidizing ability and can effectively decompose harmful substances in the air, thereby achieving the purpose of purifying the air.

[0118] The purified air flows out of the housing 91 through the air supply port 914 , enters the heat exchange air duct 5 , and continues to be circulated, thereby cleaning the components in the indoor housing 1 .

[0119] In some embodiments, the purified air flows out of the housing 91 through the air outlet 914 and enters the heat exchange air duct 5 to continue to be circulated, and finally the clean air carrying hydroxyl radicals is sent back to the room to improve the indoor air quality.

[0120] Hydroxyl free radicals can react with harmful substances in the air, such as formaldehyde, benzene and other organic volatile compounds, and decompose them into harmless small molecules, such as water and carbon dioxide, thereby reducing the pollution of harmful substances to the indoor environment. Hydroxyl free radicals can also react with pollutants in the air, such as PM2.5, bacteria, viruses, etc., destroying their chemical structure, making them inactive or decomposing them into harmless substances. Hydroxyl free radicals can also react with organic substances that produce odors and decompose them, thereby removing bad odors in the room.

[0121] However, it should be noted that although hydroxyl radicals have a positive effect on indoor environmental cleaning, there are also the following problems:

[0122] Safety: The hydroxyl radical has high activity and may damage other substances in the indoor environment (such as furniture, decoration materials, etc.), leading to problems such as material aging and fading.

[0123] Stability: The hydroxyl radical is unstable in the air and easily reacts with other substances, so its existence time is short.

[0124] In summary, the hydroxyl radical can help clean the indoor environment to a certain extent, but there are also some potential problems. In practical applications, it is necessary to comprehensively consider its advantages and disadvantages and take appropriate measures to ensure the cleanliness and safety of the indoor environment.

[0125] In some embodiments, the discharge electrode 94 is set as a dielectric barrier discharge electrode 94. Referring to FIG. 13, after the dielectric barrier discharge electrode 94 is connected to an alternating high voltage, the air can be ionized to generate plasma, in which the oxygen in the air is ionized into oxygen ions. The highly active oxygen ions react with the moisture absorbed in the water absorption component 96 to generate hydroxyl groups.

[0126] Through this series of physical and chemical processes, the hydroxyl generating device 9 effectively generates and utilizes hydroxyl radicals in the heat exchange air duct 5, achieving efficient purification of the air.

[0127] Compared with the hydroxyl generating device 9 in the related art, in the hydroxyl generating device 9 of the present application, the generation mechanism of the hydroxyl generating device 9 in the present application generates oxygen ions by ionizing air, and the oxygen ions react with water to generate hydroxyl groups.

[0128] In some embodiments, the generation of hydroxyl radicals can be qualitatively proven by the EPR (Electron Paramagnetic Resonance) detection method.

[0129] Referring to Figure 2 , the indoor air enters the housing 91 along the return air inlet 913, flows through the discharge electrode 94 and the water absorption component 96, and then carries the generated hydroxyl radicals and leaves the internal air duct 92 through the air supply outlet 914 and diffuses along the length direction of the indoor heat exchanger 7.

[0130] Referring to Figure 10 , the indoor air first enters the housing 91 through the return air inlet 913, and then flows through the discharge electrode 94. The discharge electrode 94 ionizes to generate oxygen ions. Then, the air carrying the oxygen ions flows through the water absorption component 96, and the moisture combines with the oxygen ions to generate hydroxyl radicals. The generated hydroxyl radicals then diffuse along the length direction of the indoor heat exchanger 7, purify the air flowing through the heat exchanger, effectively remove pollutants such as particulate matter, bacteria, and viruses in the air, and improve the indoor air quality.

[0131] In some embodiments, referring to Figures 10 - 12 , the hydroxyl generating device 9 further includes a flow guiding platform 97, which is installed in the internal air duct 92. The flow guiding platform 97 is disposed opposite to the air return opening 913, and the air flow blows towards the flow guiding platform 97 after passing through the air return opening 913, and carries oxygen ions through the air supply opening 914 out of the housing 91 when flowing through the discharge electrode 94.

[0132] When the indoor air enters the internal air duct 92 through the air return opening 913, it will first blow towards the flow guiding platform 97. During this process, the air flow velocity increases, and at the same time, it carries the oxygen ions generated by the discharge electrode 94. These oxygen ions are generated when the oxygen molecules are decomposed into oxygen ions due to the ionization effect when flowing through the discharge electrode 94. Subsequently, the fast air flow carrying oxygen ions passes through the internal air duct 92 and finally flows out of the housing 91 through the air supply opening 914. This process not only improves the carrying efficiency of oxygen ions, but also ensures that the air has fully contacted the discharge electrode 94 before flowing out of the housing 91, thereby enhancing the air purification effect.

[0133] Through the design and layout of the flow guiding platform 97, the hydroxyl generating device 9 can more efficiently introduce oxygen ions into the indoor air, thus playing an important role in the air purification process.

[0134] At the same time, the flow guiding platform 97 is thicker than other positions of the internal air duct 92, which directly results in less influence by the external temperature difference, thereby reducing the risk of condensation.

[0135] In some embodiments, the flow guiding platform 97 is disposed opposite to the air return opening 913, and the flow guiding platform 97 forms an arc surface along the internal air duct 92. In some embodiments, the distance between the flow guiding end surface of the flow guiding platform 97 and the end surface of the housing 91 away from the air return opening 913 decreases from the side away from the air supply opening 914 to the side close to the air supply opening 914.

[0136] In the above embodiments, the internal air duct 92 is used to connect the air return opening 913 and the air supply opening 914 to form an air circulation channel. The flow guiding platform 97 is disposed in the internal air duct 92 and corresponds to the air return opening 913. The flow guiding platform 97 forms an arc surface along the internal air duct 92, and the design of this arc surface is aimed at guiding the air flow direction.

[0137] The distance between the flow guiding end surface of the flow guiding platform 97 and the end surface of the housing 91 away from the air return opening 913 decreases gradually from the side away from the air supply opening 914 to the side close to the air supply opening 914. The purpose of this design is to increase the air flow velocity in the internal air duct 92, reduce the influence of the external temperature on the air flow temperature in the internal air duct 92, and reduce the risk of condensation.

[0138] In the present application, the hydroxyl generating device 9 is applied to the air conditioner 100. When the hydroxyl generating device 9 is installed closely to the indoor heat exchanger 7, since the air conditioner 100 is in the cooling mode, the temperature of the indoor heat exchanger 7 is very low, and the temperature of the housing 91 of the hydroxyl generating device 9 closely attached to the indoor heat exchanger 7 is also affected and reduced, resulting in a decrease in the surface temperature of the internal air duct 92. When the air flow passes through the internal air duct 92 of the hydroxyl generating device 9, there is a risk of condensation in the internal air duct 92 due to the low temperature. The formation of condensation will bring a series of safety risks and is extremely likely to cause a short circuit.

[0139] In some embodiments, since the air flow directly blows the guiding end face of the guiding platform 97 when entering the internal air duct 92 of the hydroxyl generating device 9, because the guiding platform 97 is thicker than other positions of the internal air duct 92, it directly results in that the position of the guiding platform 97 is less affected by the external temperature difference, thereby reducing the condensation risk.

[0140] As mentioned above, when used in some scenarios, there is a risk of condensation in the internal air duct 92 of the hydroxyl generating device 9. The direct safety hazard after condensation is the short circuit of the discharge electrode 94.

[0141] To solve the problem of the short circuit of the discharge electrode 94 due to condensed water. In some embodiments, referring to Figures 11 - 12 , the hydroxyl generating device 9 further includes a first mounting seat 98, which is arranged on the inner side wall of the housing 91. The first mounting seat 98 is used to mount the discharge electrode 94 so that there is a certain gap between the discharge electrode 94 and the inner side wall of the housing 91. So that even if there is some condensed water, it will not cause the discharge electrode 94 to short circuit.

[0142] By setting the first mounting seat 98, the discharge electrode 94 can be accurately positioned and installed, and at the same time, it keeps an appropriate distance from the inner side wall of the housing 91, thereby ensuring the efficient operation and safe operation of the device.

[0143] To solve the problem of the short circuit of the discharge electrode 94 due to condensed water. In some embodiments, referring to Figure 11 , the hydroxyl generating device 9 includes a plurality of drain holes 99. The drain holes 99 are arranged on the housing 91 and are used to drain the condensed water inside the housing 91. Its main function is to effectively drain the condensed water generated inside the housing 91. In some embodiments, the drain holes 99 are arranged at multiple positions on the housing 91 to ensure that the condensed water can be quickly drained under different installation methods of the discharge electrode 94.

[0144] In some embodiments, referring to Figure 11 , the hydroxyl generating device 9 further includes a diversion component 910. Its function is to divert the blown air flow to achieve the effect of sending air over a longer distance, which realizes the transportation of hydroxyl radicals over a longer distance and a larger range.

[0145] In some embodiments, the air guiding component 910 is installed at the air outlet 914 and is located outside the housing 91. The air flow at the air outlet 914 diffuses along the end face of the air guiding component 910. When there is air flow passing through the air outlet 914, the air flow will diffuse along the end face of the air guiding component 910, thereby achieving a specific air flow distribution effect. The diffusion range can also be expanded.

[0146] In some embodiments, the air conditioner 100 includes an electric control box (not shown in the figure), which is provided on one side of the indoor housing 1; it also includes an external power supply, which is provided inside the electric control box, and the external power supply is connected to the drive power supply 93 and the internal blower 95. The external power supply is respectively connected to the drive power supply 93 and the internal blower 95, thereby providing the required power support for them to ensure the normal operation of the air conditioner 100.

[0147] Such a design and configuration enable the hydroxyl generating device 9 and the air conditioner 100 to perform their respective functions more efficiently and stably, bringing a better user experience to the users.

[0148] In some embodiments, referring to Figure 11 , the housing 91 includes a first housing 901 and a second housing 902. The first housing 901 is installed on the indoor heat exchanger 7, and the second housing 902 is detachably connected to the first housing 901. The second housing 902 is provided with an air return opening 913 and an air outlet 914.

[0149] The first housing 901 is firmly installed on the indoor heat exchanger 7 to serve as the support and protection for the entire housing 91.

[0150] The second housing 902 is designed to be detachably connected to the first housing 901, which is convenient for maintenance and replacement. The second housing 902 is particularly provided with an air return opening 913 and an air outlet 914. These air openings are important components in the air conditioning system, responsible for sucking in the indoor air and then sending it out after being processed to achieve the circulation and adjustment of the indoor air.

[0151] In some embodiments, the first housing 901 is provided with a plurality of protrusions. The second housing 902 is provided with grooves corresponding to the protrusions. The cooperation between the grooves and the protrusions enables the first housing 901 and the second housing 902 to be detachably connected.

[0152] In some embodiments, referring to Figure 12 , the hydroxyl generating device 9 includes a second mounting seat 911, which is provided on the first housing 901, and the housing 91 is installed on the indoor heat exchanger 7 through the second mounting seat 911. This second mounting seat 911 is precisely set at an appropriate position on the first housing 901. Through this second mounting seat 911, the housing 91 can be stably installed on the indoor heat exchanger 7 to ensure the stability and safety of the entire system.

[0153] In some embodiments, the second mounting base 911 is mounted on the edge tube sheet 912 by screws to achieve the fixed installation of the hydroxyl generation device 9.

[0154] In some embodiments, referring to Figure 11 , the water absorption components 96 are provided with at least two, and the water absorption components 96 are arranged at intervals. It can ensure that the whole system has efficient and uniform water absorption performance.

[0155] In some embodiments, the water absorption components 96 can be made of sponge, fiber, activated carbon or other materials with high water absorption capacity. The key is that they can effectively absorb water while allowing water to react with oxygen ions.

[0156] A certain distance is maintained between each water absorption component 96, which can ensure the uniform distribution of water in the system and avoid the situation of local over-wetting or drying. This arrangement helps to improve the overall efficiency of the system and ensure that water is fully absorbed and utilized.

[0157] In the embodiments of the present disclosure, by providing the diversion platform 97, the wind resistance and condensation can be reduced, and at the same time, the condensed water can be quickly discharged through the drain hole 99. The efficiency and safety of the use of the hydroxyl generation device 9 are guaranteed. By providing the internal fan 95 and the diversion component 910, it is ensured that the hydroxyl radicals can be transported over a longer distance and in a larger range, and the purification efficiency can be improved.

[0158] On the one hand, the technical solution in this application innovates from the generation mechanism and realizes the generation of hydroxyl different from the existing solutions. On the other hand, in the process of the module structure design, through the optimized design, the wind resistance and condensation risk of the module are reduced, the diffusion distance and range of the hydroxyl radicals are increased, and the purification effect is improved.

[0159] In some embodiments, the air conditioner 100 includes a controller 21. It is used to send instructions to the air conditioner 100 to control the working process of the air conditioner 100.

[0160] The controller 21 is used to coordinate the work of the whole air conditioner 100. It includes receiving user instructions, operating in refrigeration mode, heating mode, blowing mode, shutdown mode, cleaning mode, self-cleaning mode and other modes, as well as uploading the working state of the air conditioner 100 to the cloud.

[0161] The controller 21 includes a memory 212. The memory 212 can include a high-speed random access memory 212 (RAM, Random Access Memory). It can also include a non-volatile memory 212 (NVM, Non-Volatile Memory).

[0162] For example, there is at least one disk memory 212. The memory 212 is used to store programs.

[0163] Referring to Figure 14 , the indoor controller 21 includes a communication interface 214. The communication interface 214 is used to implement communication with related components.

[0164] The communication interface of the controller 21 is used to implement communication with the drive power supply 93, the internal fan 95, and the indoor fan 8. So that after receiving the corresponding electric control signal, different components can be controlled to perform corresponding actions. For example, when receiving the air conditioner self-cleaning signal, the hydroxyl generating device 9 is controlled to act.

[0165] In some embodiments, the controller 21 is disposed in the electric control box.

[0166] The controller 21 includes a processor 213. The processor 213 is used to execute the executable module stored in the memory 212, such as a computer program, and the code of the computer program can be in the form of source code, object code, executable file, or some other forms.

[0167] The controller 21 includes a bus 211. The bus 211 is used to connect the communication interface 214 and the processor 213. The bus 211 can be an lSA bus 211, a PCI bus 211, or an ElSA bus 211, etc.

[0168] The controller 21 includes at least one software function module that can be stored in the memory 212 in the form of software or firmware.

[0169] In this application, after receiving the execution instruction, the processor 213 executes the program to implement Figure 15 the relevant control logic of the hydroxyl generating device 9 shown in

[0170] In some embodiments, the controller 21 is configured to control the drive power supply 93 to output power to the discharge electrode 94, so that the discharge electrode 94 ionizes oxygen in the air to generate oxygen ions, turn on the internal fan 95, the air flow enters the housing 91 through the return air inlet 913 and flows through the discharge electrode 94, and the oxygen ions carried by the air flow flow through the water absorption component 96, and the oxygen ions react with the moisture of the water absorption component 96 to generate hydroxyl free radicals.

[0171] In some embodiments, the ionization process of the discharge electrode 94 can work together with the operation of the internal fan 95. This means that when the internal fan 95 starts to operate, it can not only provide air flow, but also assist the discharge electrode 94 to generate ions. This synergistic effect can improve the ionization efficiency and make the ions more evenly distributed in the air.

[0172] In some embodiments, first, the ionization process of the discharge electrode 94 is carried out. After oxygen ions are generated, then the internal fan 95 is used to promote the flow of oxygen ions. This means that after the ionization process is completed, the internal fan 95 is started to push the oxygen ions to move in the air. This can ensure that the oxygen ions can be more widely distributed, thereby enhancing their impact on the environment.

[0173] In some embodiments, the internal fan 95 can be first used to drive the air flow, and then the discharge electrode 94 is used to generate oxygen ions. This means that after the air flow starts to flow, the discharge electrode 94 is activated to generate oxygen ions. This method can ensure that the oxygen ions are evenly distributed in the air flow, thereby enhancing their impact on the environment.

[0174] In some embodiments, referring to Figure 2 , under the action of the internal fan 95, the hydroxyl radicals diffuse along the length direction of the indoor heat exchanger 7 after leaving the internal air duct 92 through the air supply opening 914 with the air flow.

[0175] In some embodiments, after a period of time, the indoor fan 8 is turned on. Referring to Figure 5 , the indoor fan 8 operates to drive the hydroxyl radicals to diffuse into the interior of the heat exchange air duct 5.

[0176] Through the above steps, referring to Figure 2 、 Figure 5 , under the action of the internal fan 95, the released hydroxyl radicals diffuse horizontally along the air conditioner 100 and can cover all horizontal components and parts. And the indoor fan 8 is used to diffuse the hydroxyl radicals into the interior of the heat exchange air duct 5 and act on the various components in the heat exchange air duct 5 such as the indoor fan 8. The hydroxyl radicals can be quickly and comprehensively diffused inside the air conditioner 100 and can act on all components inside the air conditioner 100.

[0177] In some embodiments, the air conditioner 100 further includes a driving component, and the driving component is connected to the air deflector 4 to open or close the air deflector 4.

[0178] In some embodiments, the controller 21 is configured to drive the driving component to close the air deflector 4 before the discharge electrode 94 ionizes oxygen to generate oxygen ions.

[0179] The purpose of this process is to ensure that a closed or semi-closed space is formed in a specific area where oxygen is ionized to generate oxygen ions. By closing the air deflector 4, the air flow can be controlled, making the ionization process more concentrated and efficient. This can improve the ionization efficiency. The closed or semi-closed space helps to reduce the loss of oxygen, making the ionization process more concentrated, thereby improving the generation efficiency of oxygen ions.

[0180] The ion distribution can also be controlled: By adjusting the position and closed state of the air deflector 4, the distribution range of oxygen ions can be precisely controlled to ensure that they are evenly distributed in the required areas, such as in the indoor housing 1.

[0181] Closing the air deflector 4 can also reduce energy consumption. During the ionization process in an enclosed space, unnecessary energy losses can be reduced because the exchange of external air is reduced, thereby reducing the energy consumption of the system to a certain extent.

[0182] Closing the air deflector 4 can also optimize the system performance. By optimizing the environmental conditions of the ionization process, the performance of the entire system can be improved, such as the air purification efficiency, disinfection effect, etc.

[0183] After the air deflector 4 is closed, the discharge electrode 94 starts to work, ionizing oxygen through discharge to generate a large number of oxygen ions. These oxygen ions then diffuse in a specific area, playing their roles in purification, disinfection, or enhancing air quality. The orderly execution of the whole process ensures the efficient operation of the system and the achievement of the goal.

[0184] In some embodiments, the controller 21 is configured to turn off the indoor fan 8 after the indoor fan 8 has worked for a period of time to allow the hydroxyl radicals and pollutants to react fully.

[0185] After the indoor fan 8 continuously works for a period of time to circulate the air and promote the uniform distribution of hydroxyl radicals, the indoor fan 8 is turned off. This is done to provide a relatively static environment so that the hydroxyl radicals have enough time to react fully with the pollutants in the air.

[0186] The following is a detailed explanation of this step:

[0187] Stage of the indoor fan 8 working: During the period when the indoor fan 8 is turned on, it continuously circulates the air inside the indoor housing 1, enabling the hydroxyl radicals to be evenly distributed throughout the space. Hydroxyl radicals are strong oxidants that can react with various pollutants, such as harmful gases like formaldehyde and benzene, as well as microorganisms like bacteria and viruses.

[0188] Stage of turning off the indoor fan 8: After the indoor fan 8 has run for a period of time, the hydroxyl radicals in the air have been relatively fully mixed with the pollutants. At this time, turning off the indoor fan 8 can stop the air circulation, allowing the hydroxyl radicals and pollutants to undergo a more in-depth chemical reaction in a local area.

[0189] Stage of full reaction: After the indoor fan 8 is turned off, the reaction between the hydroxyl radicals and pollutants will not be interrupted due to air flow, which can ensure a more complete reaction. This full reaction helps to reduce the pollutant concentration and improve the indoor air quality.

[0190] It should be noted that after turning off the indoor fan 8, a certain amount of time needs to be given for the hydroxyl radicals to fully react with the pollutants. This time may vary depending on factors such as the type and concentration of the pollutants, the concentration of the hydroxyl radicals, and the indoor environmental conditions.

[0191] In some embodiments, the controller 21 is configured such that the hydroxyl generation device 9 and the indoor fan 8 work alternately in a cycle to cyclically purify the indoor housing 1.

[0192] The alternate cyclic operation of the hydroxyl generation device 9 and the indoor fan 8 means that within one working cycle, the hydroxyl generation device 9 works alone for a period of time first, then the device is turned off and the indoor fan 8 is turned on for air circulation. Such a cycle can be repeated to achieve the best purification effect.

[0193] According to the type and concentration of indoor pollutants and the generation rate of hydroxyl radicals, a suitable working cycle can be set.

[0194] Through the periodic alternate operation, continuous purification of the indoor air can be ensured, while avoiding possible reduction in efficiency or increase in energy consumption caused by long-term operation of a single device.

[0195] Through the above-described alternate cyclic operation mode, the air in the indoor housing 1 is effectively purified. This cyclic purification can not only remove harmful gases and microorganisms inside the air conditioner 100 and indoors, but also improve the indoor air quality, providing a healthy and comfortable living environment for the occupants.

[0196] Through the synergistic effect of the hydroxyl generation device 9 and the indoor fan 8, the cyclic purification system of the indoor housing 1 can efficiently remove various pollutants.

[0197] Refer to Figure 15 , and illustrate the control logic of the hydroxyl generation device 9 in the embodiments of the present application.

[0198] When the air conditioner 100 is in the shutdown state, the air deflector 4 at the indoor air outlet 3 is closed (S101).

[0199] Start the hydroxyl generation device 9 (S102). Specifically, the discharge electrode 94 ionizes oxygen to generate oxygen ions. Under the action of the internal fan 95, the air flow enters the outer shell 91 through the return air inlet 913, carries the oxygen ions and flows through the air supply outlet 914 and reacts with the water in the water absorption component 96 to generate hydroxyl radicals. And under the action of the internal fan 95, it diffuses outside the outer shell 91.

[0200] Under the action of the internal fan 95, the released hydroxyl radicals leave the internal air duct 92 through the air supply outlet 914 and diffuse horizontally along the indoor heat exchanger 7, covering all horizontal components and parts.

[0201] Determine whether the operating time of the hydroxyl generating device 9 reaches the first operating time T0 (S103);

[0202] In step S103, if the first operating time is reached, then execute step S104 to turn off the hydroxyl generating device 9. It is determined that hydroxyl radicals have been released and accumulated at the indoor heat exchanger 7 at this time.

[0203] In step S103, if the first operating time is not reached, then execute S103;

[0204] After executing step S104, execute step S105, and the indoor fan 8 operates at the first speed; as the indoor fan 8 rotates, the hydroxyl radicals diffuse into the interior of the heat exchange air duct 5 to act on various components in the heat exchange air duct 5 such as the indoor heat exchanger 7 and the indoor fan 8.

[0205] Determine whether the operating time of the indoor fan 8 reaches the second operating time (S106);

[0206] In step S106, if the second operating time is not reached, then execute step S106;

[0207] In step S106, if the second operating time is reached, then execute step S107 to turn off the indoor fan 8.

[0208] After standing for the third operating time (S108), loop and execute S102 to S108. Through the standing process, the hydroxyl radicals and pollutants can fully react to improve the purification efficiency.

[0209] Define S102 to S108 as the purification process. In some embodiments, the purification process loops N times. In some disclosed embodiments, the purification process is executed 2 times.

[0210] In some embodiments, after the air deflector 4 is closed after the air conditioner 100 is shut down, the internal purification mode of the air conditioner 100 can be automatically started or independently selected according to the program setting. Among them, the internal purification mode of the independently selected air conditioner 100 can be that the user sends a cleaning instruction through the remote control, and after the controller 21 receives the electrical signal, it drives the corresponding components to work.

[0211] In some embodiments, the controller 21 is configured to control the driving component to drive the air deflector 4 to close the indoor air outlet 3 when receiving the first signal.

[0212] Control the driving power supply 93 to output power to the discharge electrode 94 so that the discharge electrode 94 ionizes the oxygen in the air to generate oxygen ions, turn on the internal fan 95, the air flow enters the housing 91 through the air return port 913, flows through the discharge electrode 94, and carries the oxygen ions through the water absorption component 96, and the oxygen ions react with the moisture of the water absorption component 96 to generate hydroxyl radicals.

[0213] In some embodiments, when the working duration of the air conditioner 100 reaches a first preset time, the control driving component drives the air deflector 4 to close the indoor air outlet 3.

[0214] The control driving power supply 93 outputs power to the discharge electrode 94, so that the discharge electrode 94 ionizes oxygen in the air to generate oxygen ions, turns on the internal blower 95, the air flow enters the housing 91 through the air return opening 913, flows through the discharge electrode 94, carries the oxygen ions and flows through the water absorption component 96, and the oxygen ions react with the moisture of the water absorption component 96 to generate hydroxyl radicals.

[0215] In summary, the internal purification mode of the air conditioner involved in the present application adopts the purification method after shutdown. On the one hand, this does not affect the user's use of the air conditioner. The purification mode is preferably designed to be an automatic operation mode, that is, the air conditioner automatically runs the internal purification after the user shuts down. On the other hand, from the analysis of the reasons for the formation of internal pollution of the air conditioner, dust, bacteria, molds, odor components, etc. accumulate inside the air conditioner during the operation of the air conditioner. Especially in the cooling mode, there is condensate water inside the air conditioner, which is more likely to cause the accumulation of pollutants and the growth of bacteria and molds. The purification after shutdown can more thoroughly purify the interior comprehensively to ensure that no polluted air flow is blown out when the air conditioner is turned on again.

[0216] The internal purification mode of the air conditioner is designed such that the module first runs for a certain period of time to allow the purification factors to fully diffuse and accumulate horizontally, and then the air conditioner fan is started for vertical diffusion, ensuring that all parts inside the air conditioner can be purified.

[0217] Certainly, the hydroxyl generating device 9 designed in the present application can also be used to clean the indoor environment.

[0218] In some embodiments, the controller 21 is configured to control the driving component to drive the air deflector 4 to open the indoor air outlet 3;

[0219] The control driving power supply 93 outputs power to the discharge electrode 94, so that the discharge electrode 94 ionizes oxygen in the air to generate oxygen ions, turns on the internal blower 95, the air flow enters the housing 91 through the air return opening 913, flows through the discharge electrode 94, carries the oxygen ions and flows through the water absorption component 96, and the oxygen ions react with the moisture of the water absorption component 96 to generate hydroxyl radicals;

[0220] Under the action of the internal blower 95, the hydroxyl radicals diffuse along the length direction of the indoor heat exchanger 7 with the air flow after leaving the internal air duct 92 through the air supply opening 914;

[0221] After a period of time, the indoor blower 8 is turned on, and the indoor air enters the indoor housing 1 from the indoor air inlet 2, and carries the hydroxyl radicals to diffuse into the room through the indoor air outlet 3.

[0222] In the above embodiments, after the indoor fan 8 is turned on, the hydroxyl generating device 9 always remains in operation to ensure an adequate supply of hydroxyl radicals throughout the purification process.

[0223] In some embodiments, the controller 21 is configured to open the air deflector 4, control the drive power supply 93 to output power to the discharge electrode 94, so that the discharge electrode 94 ionizes oxygen in the air to generate oxygen ions, turn on the internal fan 95, the air flow enters the housing 91 through the air return port 913, flows through the discharge electrode 94, and carries the oxygen ions through the water absorption component 96, and the oxygen ions react with the moisture of the water absorption component 96 to generate hydroxyl radicals;

[0224] Under the action of the internal fan 95, the hydroxyl radicals diffuse along the length direction of the indoor heat exchanger 7 with the air flow after leaving the internal air duct 92 through the air supply port 914;

[0225] After a period of time, the drive power supply 93 and the internal fan 95 are turned off, and the indoor fan 8 is turned on to drive the hydroxyl radicals to diffuse into the room.

[0226] Through the periodic alternating operation among the drive power supply 93, the internal fan 95 and the indoor fan 8, the continuous purification of the indoor air can be ensured, and at the same time, the reduction in efficiency or the increase in energy consumption that may be caused by the long-term operation of a single device can be avoided.

[0227] Through the above alternating cycle working mode, the air in the indoor housing 1 is effectively purified. This cyclic purification can not only remove harmful gases and microorganisms inside the air conditioner 100 and in the room, but also improve the indoor air quality, providing a healthy and comfortable living environment for the occupants. Through the synergistic effect of the hydroxyl generating device 9 and the indoor fan 8, the cyclic purification system of the indoor housing 1 can efficiently remove various pollutants.
