[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] As mentioned in the background technology, as a household electrical appliance for regulating and controlling indoor temperature and humidity, the scope and frequency of use of air conditioners are gradually increasing, while the use of air conditioners in kitchen spaces has developed relatively slowly. The main reason is that due to the harsh environment of the kitchen with many heat sources, high humidity and heavy oil smoke, it is difficult for traditional air conditioners to operate well for a long time in such an environment. Existing kitchen air conditioners and air conditioning systems have problems such as high noise, poor oil smoke protection or difficulty in cleaning, direct cold air blowing and high cost. Therefore, in the air conditioner of the present application, a first air inlet 130 is provided at one end of the casing 100 close to the mounting panel, and the back air intake method is adopted, which can reduce the direct inhalation of oil smoke into the air conditioner and alleviate the problem of the air conditioner filter being easily dirty and blocked.

[0034] Please refer to Figures 1 to 5 The present application provides an air conditioner, comprising: a casing 100, a mounting panel 110 is provided on the casing 100, the mounting panel 110 is used to connect with a target mounting surface so as to mount the casing 100 on the target mounting surface, a first air duct 120 is provided in the casing 100; a first air inlet 130 is provided on the casing 100 and close to one end of the mounting panel 110, the first air inlet 130 is communicated with the first air duct 120; a first filter component 200 is provided in the first air duct 120, the first filter component 200 is arranged opposite to and spaced from the mounting panel 110, an air inlet channel 140 is provided between the first filter component 200 and the mounting panel 110, the first air inlet 130 is communicated with the air inlet channel 140.

[0035] The air conditioner provided according to the present application includes a casing 100, a first air inlet 130 and a first filter component 200. The casing 100 is provided with a mounting panel 110, and the mounting panel 110 is used to connect with a target mounting surface so as to mount the casing 100 on the target mounting surface. A first air duct 120 is provided in the casing 100. The first air inlet 130 is provided on the casing 100 and close to one end of the mounting panel 110, and the first air inlet 130 is communicated with the first air duct 120; the first filter component 200 is provided in the first air duct 120, and the first filter component 200 is arranged opposite to and spaced from the mounting panel 110, and an air inlet channel 140 is provided between the first filter component 200 and the mounting panel 110, and the first air inlet 130 is communicated with the air inlet channel 140. The air conditioner of the present application is suitable for installation in a kitchen environment. By setting a mounting panel 110 connected to the target mounting surface on the housing 100, and setting a first air inlet 130 at one end close to the mounting panel 110, the design concept of back-side air intake is realized. Since the first air inlet 130 is set close to the wall, the path and opportunity for oil smoke to directly enter the air conditioner can be effectively reduced. At the same time, the air inlet channel 140 is connected to the first air inlet 130, and while ensuring the air intake, oil smoke and impurities are intercepted by the first filter component 200 before entering the air duct, which significantly improves the oil smoke filtration efficiency, reduces the accumulation of oil smoke inside the air conditioner, and reduces maintenance costs.

[0036] Since the amount of oil smoke from the back air intake is reduced, the heat exchanger, cross-flow fan blades and other components of the air conditioner are less susceptible to the impact of oil smoke, and run more smoothly, reducing the extra energy consumed by the air conditioner due to oil smoke blockage, achieving energy-saving effects.

[0037] Specifically, there are multiple first air inlets 130, and each first air inlet 130 is connected to the air inlet channel 140. The setting of multiple first air inlets 130 can significantly increase the air flow of the air inlet channel 140, especially in an environment such as a kitchen with heavy oil smoke and obstructed air circulation, it can more efficiently introduce external fresh air and improve the efficiency of introducing fresh air, thereby effectively reducing the oil smoke concentration of the air inside the kitchen and keeping the kitchen environment fresh. The setting of multiple air inlets can better adapt to the layout and environmental requirements of different kitchens. Even in the case of dense kitchen equipment and diverse sources of oil smoke, it can ensure that the air conditioner has sufficient air intake to maintain the circulation and air quality of the kitchen air.

[0038] By dispersing the air inlet points of the air conditioner, the noise during the air intake process can also be reduced, creating a quieter usage environment for users.

[0039] In the specific implementation process, the air conditioner further includes: an air inlet baffle 131, which is arranged on the housing 100 and located at the first air inlet 130, and the position of the air inlet baffle 131 is movably arranged so that the first air inlet 130 is opened or closed. There are multiple air inlet baffles 131, and the multiple air inlet baffles 131 are arranged one-to-one corresponding to the multiple first air inlets 130. When the air conditioner is not in use, the air inlet baffle 131 can close the first air inlet 130, effectively blocking the oil smoke and dust in the kitchen from entering the interior of the air conditioner, reducing the erosion of the oil smoke on the internal parts of the air conditioner, and reducing the cleaning frequency and maintenance cost of the filter. During the period when the kitchen is not in use or the air conditioner is turned off, the closed state of the air inlet baffle 131 can maintain the clean state of the interior of the air conditioner and extend the service life of the air conditioner.

[0040] The movable design of the air inlet baffle allows the size of the air inlet to be adjusted as needed when the air conditioner is running, which not only helps to control the amount of air entering the air conditioner, but also reduces the noise generated when the air is entering to a certain extent.

[0041] Preferably, the air inlet baffle 131 is rotatably arranged around a predetermined axis, and the air inlet flow rate is adjusted by controlling the rotation angle of the air inlet baffle 131.

[0042] In this application, if Figure 2 As shown, the width of the air inlet channel 140 is M, wherein 40 mm < M < 80 mm. Preferably, M is 60 mm. Compared with the conventional wall-mounted air conditioner, in the present application, the wall-mounted structure of the air conditioner is extended so that there is a spacing between the mounting panel 110 and the first filter component 200, and the value of M is adjusted so that when it is between 40 mm and 80 mm, the air inlet attenuation effect is optimal.

[0043] In addition, the optimized design of the air inlet channel width M ensures that the air conditioner can obtain sufficient air intake while filtering the oil smoke. Sufficient air intake is a necessary condition for the efficient operation of the air conditioner, especially when operating at high power. The appropriate M value can ensure that the air conditioner can still maintain good cooling or heating performance in the special environment of the kitchen.

[0044] like Figure 3As shown, the air conditioner further includes: a second air duct 310, which is arranged in the housing 100 and is located on the side of the first air duct 120; a second air inlet 320, which is arranged on the housing 100 and is connected to the outdoor air; and a second air outlet 330, which is arranged on the housing 100, and the two ends of the second air duct 310 are respectively connected to the second air inlet 320 and the second air outlet 330. Among them, the second air duct 310 is a fresh air passage. Due to the long-term operation of the cooking equipment in the kitchen, the air pressure and oxygen concentration are reduced. Combined with the oxygen-enriched fresh air function, the kitchen air conditioner of the present invention can automatically adjust the oxygen concentration in the kitchen when the range hood is working, avoid the reduction of air pressure and oxygen deficiency in the kitchen, thereby reducing the risk of carbon monoxide and other toxic gases produced by incomplete combustion of the gas stove, and improving the safety of the kitchen environment.

[0045] The fresh air introduced through the second air duct 310 can reduce the impact of high-temperature fresh air on the kitchen environment temperature after oxygen enrichment treatment, providing an effective solution for controlling indoor temperature fluctuations in the kitchen and avoiding a sudden increase in indoor temperature when the fresh air is turned on, thereby improving the user's comfort in the kitchen environment.

[0046] The second air duct 310 is designed as an independent fresh air processing channel, which reduces the interference between fresh air processing and indoor circulating air processing, allowing the air conditioner to adjust temperature and humidity more efficiently, while also reducing energy consumption during fresh air processing, thereby achieving the goal of energy conservation and emission reduction. The design of the second air duct 310 allows the air conditioner to intelligently control the amount of fresh air according to actual needs in the kitchen, and automatically adjust the opening and closing of the second air inlet 320 and the air volume of the second air duct 310 by monitoring the state of the kitchen range hood and the oxygen concentration, so as to achieve the best kitchen environment adjustment effect.

[0047] In a specific implementation, the air conditioner further includes: an air outlet channel 340, which is arranged on the housing 100, and the two ends of the air outlet channel 340 are respectively connected to the second air duct 310 and the second air outlet 330; a second filter component 400, which is arranged in the air outlet channel 340, and the airflow flowing into the second air inlet 320 is filtered by the second filter component 400 and blown out through the second air outlet 330. Among them, the second filter component 400 is a permeable membrane, and the permeable membrane uses a polymer membrane material with selective permeability, so that oxygen molecules are easier to pass through the membrane than nitrogen molecules, that is, membrane oxygen production, which can separate the outdoor fresh air into oxygen-rich gas with an oxygen concentration of 25% to 30%, which can play a role in regulating the indoor oxygen concentration. During the cooking process in the kitchen, the strong exhaust of the range hood may cause the indoor oxygen concentration to decrease. The second filter component 400 can maintain a suitable oxygen concentration in the kitchen by increasing the oxygen ratio to avoid the generation of toxic gases due to insufficient combustion of the gas stove.

[0048] Furthermore, the air conditioner further comprises: an exhaust passage 500, which is arranged in the housing 100, and the air inlet of the exhaust passage 500 is arranged opposite to the second filter component 400, and a part of the airflow flowing into the second air inlet 320 is blown out after being filtered by the second filter component 400, and the other part of the airflow is discharged to the outside through the exhaust passage 500. When the outdoor fresh air passes through the second filter component 400, the oxygen-rich gas passes through the permeable membrane and is discharged into the room, and the filtered nitrogen-rich gas is discharged to the outside through the exhaust passage 500.

[0049] Oxygen is filtered through the second filter component 400, part of the oxygen-enriched air is introduced into the kitchen, and the other part of the non-oxygen-enriched air is discharged through the exhaust channel 500. This can not only maintain a suitable level of oxygen concentration in the kitchen, but also avoid safety hazards caused by excessive oxygen concentration.

[0050] In the present application, the second filter component 400 is arranged at an angle in the air outlet channel 340, and a confluence groove 341 is arranged on the inner wall surface of the air outlet channel 340. The confluence groove 341 is recessed relative to the inner wall surface, and the confluence groove 341 is arranged opposite to the second filter component 400; wherein, the confluence groove 341 is connected to the exhaust channel 500.

[0051] The inclined setting of the second filter component 400 can optimize the path of the airflow, make the air flow through the permeable membrane more evenly, improve the permeation efficiency, ensure that the oxygen in the airflow is fully extracted, and reduce the fluid resistance to improve the smoothness of the airflow. The inclined second filter component 400 cooperates with the confluence groove 341 so that the non-permeable gases such as nitrogen in the air are effectively separated and guided into the confluence groove 341. Since the confluence groove 341 is concave relative to the inner wall surface, it can accumulate the separated nitrogen-rich gas to prevent this part of the gas from being re-mixed into the oxygen-rich air, thereby improving the purity of the oxygen-rich air.

[0052] The optimized airflow path and efficient gas separation effect help reduce the energy consumption of the air conditioner when the oxygen-enriched fresh air function is running. By reducing the resistance of gas flow and improving the penetration efficiency, the air conditioner can run at a lower power, achieving the goal of energy saving and emission reduction.

[0053] In specific implementation, Figure 5As shown, the air conditioner further includes: a second air outlet baffle 600, which is arranged on the housing 100 and located at the second air outlet 330, and the position of the second air outlet baffle 600 is movably arranged so that the second air outlet 330 is opened or closed. The movable design of the second air outlet baffle 600 allows the air conditioner to intelligently adjust the opening and closing of the second air outlet 330 according to the air quality, oxygen concentration and working state of the range hood in the kitchen. When the oxygen concentration in the kitchen reaches a preset threshold or the range hood is turned off, the second air outlet baffle 600 can automatically close the second air outlet 330, reduce unnecessary introduction of fresh air, and save energy. Conversely, when the amount of fresh air needs to be increased, the second air outlet baffle 600 can automatically adjust its position to open the second air outlet 330, ensure air circulation in the kitchen, and improve air quality.

[0054] By controlling the opening degree of the second air outlet 330, the amount of fresh air introduced into the kitchen can be accurately controlled, thereby avoiding large fluctuations in indoor temperature due to the introduction of fresh air. Especially in the hot summer, it prevents the high-temperature fresh air outside from directly entering the kitchen, causing the indoor temperature to rise, affecting the air conditioning cooling effect and user comfort. The setting of the second air outlet baffle 600 also plays a role in preventing dust and oil smoke. When the air conditioner does not use the fresh air function, the second air outlet baffle 600 can close the second air outlet 330 to reduce the intrusion of oil smoke and dust, which helps to keep the inside of the air conditioner clean and extend the service life of the equipment.

[0055] Preferably, the second air outlet 330 is arranged on the top panel 150 of the housing 100, and the air conditioner further comprises: a first air outlet 160, which is arranged on the side panel 170 of the housing 100, the first air outlet 160 is connected to the first air duct 120, and the side panel 170 is arranged opposite to the mounting panel 110. The second air outlet 330 on the top panel 150 is mainly responsible for conveying fresh air to the space above the kitchen. At the same time, the first air outlet 160 is located at one end of the side panel 170 close to the top panel 150, which can better achieve the sinking of cold air and avoid direct blowing of cold air. A first air outlet baffle 161 is arranged at the first air outlet 160, and the position of the first air outlet baffle 161 is movably arranged to open or close the first air outlet 160.

[0056] When the air conditioner is started, the air inlet damper 131 is opened and the first fan 700 is started. Hot air is sucked from the upper and lower sides of the air conditioner to the back of the air conditioner, and after heat exchange in the condenser, it is blown out to the upper part through the cross-flow duct, realizing the function of not blowing cold air directly.

[0057] The cross-flow air duct of the air conditioner adopts the working mode of back air intake and upper air outlet. Since the kitchen environment requires more air conditioning cooling mode, the upper air outlet can better achieve the sinking of cold air and avoid direct cold air blowing. The back air intake can reduce the direct inhalation of oil smoke into the air conditioner and alleviate the problem of the air conditioner filter being easily dirty and blocked. At the same time, since the back of the wall-mounted air conditioner is close to the wall, the back air intake needs to be designed with a special shell to ensure the air intake.

[0058] The inner wall surface of the mounting panel 110 is provided with reinforcing ribs, which protrude from the inner wall surface by 2 mm to 5 mm, and extend from the top panel 150 to the bottom panel of the housing 100 .

[0059] Refer to the attached Figure 4 With attached Figure 5 According to the top view and the bottom view of the air conditioner, it can be seen that a grille-shaped bottom shell structure is designed, and air inlet baffles are provided at the upper and lower air inlets, which can ensure dust and smoke prevention when the air conditioner is turned off, and ensure smooth air inlet to the crossflow duct when the air conditioner is turned on. In order to ensure the structural strength of the bottom shell, the wall-mounted mechanism of the bottom shell, which is subjected to greater force, is reinforced to ensure the structural strength of the bottom shell. Due to the back air intake form, the air conditioner filter assembly is arranged on the back of the air conditioner, and the dust removal device is difficult to clean the oil stains. A quick-release straight plate filter is used to facilitate users to quickly clean or replace the filter assembly.

[0060] An oxygen-enriched fresh air centrifugal duct is arranged on the left side of the air conditioner, wherein the fresh air duct is divided into an air intake duct and an exhaust duct. When the oxygen-enriched mode is started, the fresh air vent baffle is opened, the centrifugal fan blades are started, and the outside air enters the centrifugal duct (i.e., the second air duct 310) from the air intake duct and is discharged to the flat permeable membrane. The flat permeable membrane uses a polymer membrane material with selective permeability characteristics, so that oxygen molecules are easier to pass through the membrane than nitrogen molecules. This method can separate oxygen-enriched gas with an oxygen concentration of 25% to 30%. The oxygen-enriched gas passes through the membrane and is discharged into the room from the oxygen-enriched pipe, while the nitrogen-enriched gas is discharged from the exhaust duct 500 to the outside through the exhaust pipe.

[0061] See also Figure 6 and Figure 7 The present application also provides a control method for an air conditioner, the air conditioner is the air conditioner of the above embodiment, the air conditioner is connected to the range hood by signal, and the control method includes:

[0062] Get the operating status of the range hood;

[0063] When the range hood is in the on state, the second air duct 310 is controlled to be opened;

[0064] When the range hood is in a turned-off state, obtaining a first actual oxygen content in the environment where the air conditioner is located;

[0065] comparing a first actual oxygen content with a first preset oxygen content;

[0066] According to the comparison result, the second air duct 310 is controlled to be opened or closed.

[0067] When the range hood is turned on, the second air duct 310 automatically opens to introduce fresh air and increase the oxygen content, which helps to keep the oxygen concentration in the kitchen within a safe range and avoid the decrease in the oxygen concentration in the kitchen due to the long-term operation of the range hood. When the range hood is turned off, the air conditioner will detect the first actual oxygen content of the current environment and compare it with the preset first preset oxygen content. If the actual oxygen content meets the preset standard, the second air duct 310 can be closed, which reduces the unnecessary introduction of fresh air and reduces the energy consumption of the air conditioner when adjusting the indoor temperature. The control method of the present application not only solves the special needs in the kitchen environment, such as oxygen concentration adjustment, energy saving, noise control and oil fume odor management, but also improves the intelligence level of the system, simplifies user operation, realizes all-round intelligent management of kitchen air conditioners, and provides users with a healthier, more comfortable, safe and convenient kitchen environment.

[0068] Further, in the first embodiment provided in the present application, when the range hood is in the on state, after controlling the second air duct 310 to open, the control method further includes:

[0069] Obtaining a second actual oxygen content of the current environment of the air conditioner;

[0070] comparing a second actual oxygen content with a second preset oxygen content;

[0071] According to the comparison result, the flow rate of the airflow in the second air duct 310 is controlled.

[0072] By obtaining the second actual oxygen content of the current environment of the air conditioner in real time and comparing it with the second preset oxygen content, the present application can dynamically manage the oxygen concentration in the kitchen. When the range hood is turned on and the oxygen concentration in the kitchen decreases, the intelligent controller can respond quickly, automatically increase the airflow in the second air duct 310, introduce more fresh air rich in oxygen, and quickly restore the oxygen concentration in the kitchen to a safe level, avoiding the incomplete combustion of the gas stove to produce harmful gases such as carbon monoxide. While introducing fresh air, by controlling the airflow, the indoor temperature fluctuation problem caused by the introduction of a large amount of fresh air can be effectively avoided. The intelligent control algorithm can adjust the amount of oxygen-rich fresh air introduced according to the current condition of the kitchen (such as the heat generated by cooking, the sealing degree of the kitchen, etc.), ensure the stability of the kitchen environment temperature, and provide a more comfortable cooking experience. The intelligent control method automatically adjusts the airflow of the second air duct 310 according to the real-time changes in the oxygen concentration in the kitchen, avoids unnecessary over-ventilation, reduces the energy consumption of the centrifugal fan, and realizes an efficient and energy-saving fresh air introduction mechanism.

[0073] Further, the second preset oxygen content includes a first oxygen threshold, a second oxygen threshold and a third oxygen threshold which increase in sequence;

[0074] When the second actual oxygen content is within the first oxygen threshold range, the air flow rate in the second air duct 310 is controlled to be at the first gear;

[0075] When the second actual oxygen content is within the second oxygen threshold range, the air flow rate in the second air duct 310 is controlled to be at the second gear position;

[0076] When the second actual oxygen content is within the third oxygen threshold range, the air flow rate in the second air duct 310 is controlled to be at the third gear;

[0077] The air flow rate at the first gear is greater than the air flow rate at the second gear, which is greater than the air flow rate at the third gear.

[0078] According to different levels of the second actual oxygen content, the present invention can intelligently adjust the airflow in the second air duct 310, and set it to the first gear, the second gear, and the third gear respectively. This hierarchical control strategy ensures that the oxygen concentration in the kitchen environment can be maintained within an appropriate range, avoiding health risks caused by too low oxygen concentration, and also preventing fire hazards that may be caused by too high oxygen concentration.

[0079] The airflow rate in the first gear is set to a larger value, which is suitable for situations where the oxygen concentration in the kitchen drops significantly, and quickly increases the oxygen concentration to a safe level. When the oxygen concentration gradually recovers, the airflow rate decreases successively. This adaptive control method avoids unnecessary energy waste and improves the efficiency and economy of the system. By intelligently adjusting the airflow rate, the present application can reduce indoor temperature fluctuations caused by the introduction of fresh air, avoid the user's experience of hot and cold temperatures when cooking, and improve the comfort and stability of the kitchen environment.

[0080] The graded oxygen threshold setting enables the air conditioner to respond quickly to changes in oxygen concentration in the kitchen and quickly adjust to the most appropriate working state. This instant response capability is crucial to ensuring the stability of air quality in the kitchen, especially during peak cooking periods, when oxygen can be quickly replenished to maintain the normal combustion efficiency of cooking equipment.

[0081] In the second embodiment provided in the present application, when the range hood is in the on state, after controlling the second air duct 310 to open, the control method further includes:

[0082] Get the air volume level of the range hood;

[0083] The flow rate of the airflow in the second air duct 310 is adjusted according to the air volume level of the range hood.

[0084] When the range hood is turned on, its air volume level reflects the emission speed of oil smoke and moisture in the kitchen, as well as the changing trend of the kitchen air pressure and oxygen concentration. Automatically adjusting the air flow rate of the second air duct 310 according to the air volume level of the range hood can ensure the stability of the oxygen concentration in the kitchen, avoid the air pressure imbalance and oxygen concentration drop caused by the range hood being turned on, and thus ensure the sufficiency and safety of gas combustion.

[0085] Specifically, the air volume gears of the range hood include a high air volume gear, a medium air volume gear and a low air volume gear. When the range hood is in the high air volume gear, the air flow rate in the second air duct 310 is controlled to be at the first gear; when the range hood is in the medium air volume gear, the air flow rate in the second air duct 310 is controlled to be at the second gear; when the range hood is in the low air volume gear, the air flow rate in the second air duct 310 is controlled to be at the third gear.

[0086] In a third embodiment provided in the present application, a method for comparing a first actual oxygen content with a first preset oxygen content includes:

[0087] The first preset oxygen content includes a first oxygen threshold, a second oxygen threshold, and a third oxygen threshold that increase in sequence;

[0088] When the first actual oxygen content is within the first oxygen threshold range, the air flow rate in the second air duct 310 is controlled to be at the first gear;

[0089] When the first actual oxygen content is within the second oxygen threshold range, the air flow rate in the second air duct 310 is controlled to be at the second gear position;

[0090] When the first actual oxygen content is within the third oxygen threshold range, the air flow rate in the second air duct 310 is controlled to be at the third gear;

[0091] The air flow rate at the first gear is greater than the air flow rate at the second gear, which is greater than the air flow rate at the third gear.

[0092] Since the airflow rate of the first gear is greater than that of the second gear, and the airflow rate of the second gear is greater than that of the third gear, when the oxygen concentration in the kitchen approaches or reaches a higher threshold, the air conditioner will automatically reduce the airflow rate to avoid unnecessary introduction of fresh air, thereby significantly reducing energy consumption and improving the overall energy efficiency of the system. This control strategy eliminates the need for users to manually adjust the airflow rate. The system can automatically adjust according to the real-time detected oxygen concentration, simplifying the operation process and improving the user experience, especially for users who are not familiar with air conditioner operation. Such intelligent design improves the ease of use of the device.

[0093] In the present application, a second fan 800 is arranged in the second air duct 310, and the rotation speed of the second fan 800 corresponding to the first gear is 1100rpm~1300rpm; the rotation speed of the second fan 800 corresponding to the second gear is 900rpm~1100rpm; the rotation speed of the second fan 800 corresponding to the third gear is 700rpm~900rpm.

[0094] In the oxygen-enriched fresh air function control method, when the oxygen concentration is between 18% and 22%, it is considered to be a safe working environment standard, suitable for users to live and work for a long time. An oxygen concentration below 16% will cause obvious discomfort, and above 24% will increase the fire risk level of kitchen fires. Therefore, intelligent control requirements are put forward for the oxygen content in the kitchen. In this control method, the oxygen concentration in the kitchen air is set to ρ, the first / second preset oxygen content is 21%, the first oxygen threshold is ρ<19%, the second oxygen threshold is 19%≤ρ<20%, and the third oxygen threshold is 20%≤ρ<21%.

[0095] The oxygen-enriched fresh air function controller consists of an oxygen content probe and a range hood IoT. The oxygen content probe is used to monitor the oxygen content in the kitchen air. The range hood IoT is connected through wireless signal transmission to monitor the working status of the range hood. When it is detected that the oxygen content in the kitchen does not reach the start threshold or the range hood is turned off, the oxygen-enriched fresh air function is turned off. During operation, the controller data is continuously monitored and fed back. When the oxygen content in the kitchen or the working status of the range hood changes, the working position of the oxygen-enriched fresh air function is adjusted until the air conditioner is turned off.

[0096] The air conditioner of the present application adopts a wall-mounted split air conditioner with back air intake and upper air outlet, which reduces the environmental noise of multiple kitchen equipment, avoids the discomfort caused by direct cold wind, and the back air intake can reduce the amount of oil smoke directly inhaled into the air conditioner. In order to ensure the air intake of the air conditioner, the housing 100 is designed so that the distance between the filter screen and the mounting panel 110 is 60mm. An oxygen-enriched fresh air structure is designed, and fresh air is inhaled by a centrifugal fan, and oxygen is filtered and produced by a permeable membrane method, thereby reducing the impact of fresh air on indoor temperature and achieving the purpose of balancing the kitchen air pressure and oxygen concentration. A controller and a control method for the oxygen-enriched fresh air function are designed, and the working state of the oxygen-enriched fresh air function is continuously feedback-controlled and adjusted by monitoring the state of the kitchen range hood and the oxygen concentration, so that the kitchen maintains a stable, comfortable and safe atmospheric environment. The problem of high noise in the kitchen and poor comfort caused by air conditioning refrigeration is solved, and the problem of poor oil smoke prevention effect of the air conditioner is solved; the problem of unbalanced air pressure between the enclosed kitchen environment and the outside world and the reduction of oxygen concentration caused by the long-term operation of the gas stove range hood is solved; the problem of automatically adjusting the oxygen content for the kitchen environment is solved.

[0097] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0098] The air conditioner provided according to the present application includes a casing 100, a first air inlet 130 and a first filter component 200. The casing 100 is provided with a mounting panel 110, and the mounting panel 110 is used to connect with a target mounting surface so as to mount the casing 100 on the target mounting surface. A first air duct 120 is provided in the casing 100. The first air inlet 130 is provided on the casing 100 and close to one end of the mounting panel 110, and the first air inlet 130 is communicated with the first air duct 120; the first filter component 200 is provided in the first air duct 120, and the first filter component 200 is arranged opposite to and spaced from the mounting panel 110, and an air inlet channel 140 is provided between the first filter component 200 and the mounting panel 110, and the first air inlet 130 is communicated with the air inlet channel 140. The air conditioner of the present application is suitable for installation in a kitchen environment. By setting a mounting panel 110 connected to the target mounting surface on the housing 100, and setting a first air inlet 130 at one end close to the mounting panel 110, the design concept of back-side air intake is realized. Since the first air inlet 130 is set close to the wall, the path and opportunity for oil smoke to directly enter the air conditioner can be effectively reduced. At the same time, the air inlet channel 140 is connected to the first air inlet 130, and while ensuring the air intake, oil smoke and impurities are intercepted by the first filter component 200 before entering the air duct, which significantly improves the oil smoke filtration efficiency, reduces the accumulation of oil smoke inside the air conditioner, and reduces maintenance costs.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
