[0055] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0056] It should be noted that the user information (including but not limited to user equipment information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data authorized by the user or authorized by all parties, and the collection, use and processing of related data need to comply with relevant regulations; and the acquisition, storage, processing, transmission, etc. of data comply with the relevant regulations of laws and regulations. In the embodiments of the present application, some industry existing solutions such as software, components, models, etc. may be mentioned, which should be considered as exemplary, and the purpose is only to illustrate the feasibility in the implementation of the technical solutions of the present application, but it does not mean that the applicant has or will necessarily use the solution.

[0057] The steam oven is a kitchen appliance that combines cooking and baking functions. It mainly relies on the built-in steam generator and heating element to cook food. The steam oven combines steaming, baking, stewing, and boiling, and a machine can meet different cooking needs, save kitchen space, and make the kitchen more tidy. High-temperature steam cooking can better preserve the nutritional ingredients of food, making the food taste more delicious and full. At the same time, high-temperature steam can effectively kill bacteria and ensure food hygiene.

[0058] In daily life, people hope to record videos or photos when cooking food to share on short video platforms or friend circles, but when using the existing steam mode of the steam oven to cook food, the condensation liquid water droplets on the visible window of the steam oven block the camera, causing the photo or video recording to be blurred and unclear.

[0059] Based on this, as shown in the Figure 1 The present application provides a steam oven, which comprises a cooking shell 10, a heating assembly 20, a temperature sensing assembly 30, a steam generator 40, a fan 50, and a controller 60; the controller 60 is connected to the heating assembly 20, the temperature sensing assembly 30, the steam generator 40, and the fan 50; the cooking shell 10 has a cooking cavity 11 for placing food to be processed; the heating assembly 20, the temperature sensing assembly 30, the steam generator 40, and the fan 50 are all arranged in the cooking cavity 11; the cooking shell 10 includes a visible window 12; the heating assembly 20 is used to heat the air in the cooking cavity 11; the temperature sensing assembly 30 is used to detect the temperature in the cooking cavity 11; the controller 60 is used to control the steam generator 40 to generate steam when the temperature in the cavity reaches the vaporization temperature of water; the controller 60 is also used to control the fan 50 to output air flow to the visible window 12 when liquid appears on the visible window 12.

[0060] The cooking shell 10 refers to a structure or device that covers, covers or protects food or cooking utensils during cooking. Specifically, the cooking shell 10 refers to the external structure of a cooking utensil (such as an electric rice cooker, oven, microwave oven, etc.), which is usually made of metal, plastic or other heat-resistant materials, used to protect internal mechanisms and components, while providing an attractive appearance and easy-to-clean surface. The heating assembly 20, also known as an electric heating element or heating assembly, is a device that converts electrical energy into heat energy. In this application, the heating assembly 20 may, for example, be a heating tube for emitting heat to heat the air in the cooking cavity 11. The heating tube, also known as an electric heating tube or electric heating tube, is an electric heating element that converts electrical energy into heat energy using the principle that electric current passing through a conductor generates Joule heat. The temperature sensing assembly 30, also known as a temperature sensitive element or temperature sensor, is a device that can sense temperature and convert it into a measurable or identifiable signal. Specifically, the temperature sensing assembly 30 can use the principles of thermoelectric effect, resistance effect, thermistor effect, thermal resistance effect, thermocouple effect, etc. to convert temperature signals into electrical signals or other identifiable signals. For example, the temperature sensing assembly 30 can be a temperature sensing bag or temperature sensor, etc.

[0061] The steam generator 40 is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. It mainly consists of a water tank, an electric heating element, a control device and a safety device. The working principle of the steam generator 40 is to use fuel or other energy sources to generate heat energy inside the device, thereby heating water to obtain steam. Inside the steam generator 40, there is a circulation system that when the temperature decreases, the steam will become water again and enter the system to be heated, thereby ensuring the full use of resources. Specifically, the working process of the steam generator 40 is: through heat transfer and water vaporization, high-temperature and high-pressure steam is generated. The steam generator 40 may, for example, be an electromagnetic steam generator 40, an electric steam generator 40, a fuel oil steam generator 40, a gas steam generator 40, etc.

[0062] The blower 50 is a mechanical device used for sucking, discharging or compressing gas, and is a machine that converts the mechanical energy of a prime mover into gas energy. It is a device that relies on input mechanical energy to increase gas pressure and discharge gas. The working principle of the blower 50 is mainly to use the rotation of the blades on the wind wheel to push the air flow. When the blower 50 starts to work, the blades will suck the surrounding air into the inside of the blower 50, and then through the coordinated action of the bearing, motor and reducer to increase the rotating speed of the wind wheel, so as to blow the air out of the blower 50. The driving force of the blower 50 comes from the horizontal and vertical thrust on the blades. The controller 60 refers to a master device that can receive and process signals. It is the "decision-making mechanism" that issues commands, and can coordinate and command the operation of the entire system or device. The working principle of the controller 60 is to receive signals from sensors or other input devices, make judgments and processing according to predetermined programs or logic, and then output corresponding control signals to realize the control of the device or system.

[0063] The cooking cavity 11 is a key component in the cooking device, which provides a closed or semi-closed space for containing food and conducting the cooking process. The cooking cavity 11 is a space inside the cooking device (such as oven, steam oven, microwave oven, etc.), which mainly functions to contain food and make it fully cooked through heating, steam or other cooking methods. In this application, the cooking shell 10 has a cooking cavity 11 for placing food to be processed, that is, the cooking shell 10 contains the cooking cavity 11, and the inner wall of the cooking shell 10 can be attached to the cooking cavity 11 or have a gap. The viewing window 12 refers to a window through which one side can be seen from the other side, for example, the viewing window 12 can be made of transparent glass, and the user cooking food can clearly see the food cooking situation inside the steam oven through the viewing window 12. The vaporization temperature of water, also known as saturation temperature or boiling point, is the temperature at which water changes from liquid to gas (i.e. vaporization or boiling). This temperature is directly related to the external pressure of water. Under a certain pressure, water will only vaporize at this fixed temperature, and as the external pressure changes, the vaporization temperature of water will also change accordingly. For example, under standard atmospheric pressure (101.325 kPa), the vaporization temperature of water is 100°C.

[0064] Specifically, after the user places food into the steaming oven and turns on the steaming mode, the cavity air in the cooking cavity 11 needs to be heated by the heating assembly 20 first, and the cavity temperature in the cooking cavity 11 is detected by the temperature sensing assembly 30. In the case that the cavity temperature reaches the water vaporization temperature, it can be ensured that the temperature of the steam will not decrease when it encounters cold, so that the steam will not condense into liquid water when it encounters cold, and the liquid on the visual window 12 is avoided. Therefore, the controller 60 can control the steam generator 40 to generate steam, so as to avoid the steam encountering the inner wall of the cooking cavity 11 with lower temperature and condensing into liquid water. In order to ensure the clarity of the shooting, the controller 60 can also control the fan 50 to output air flow to the visual window 12 when liquid appears on the visual window 12, so as to aggregate small liquid into large liquid and blow it to the bottom of the cooking cavity 11. For example, the way to determine whether liquid appears on the visual window 12 can include two ways: one is that the visual window 12 is divided into multiple detection areas 121, each detection area 121 is provided with a corresponding infrared detection assembly 70, and each infrared detection assembly 70 is connected to the controller 60. The controller 60 controls the infrared detection assembly 70 to emit infrared rays, determines the infrared detection signal of the corresponding detection area 121 of the visual window 12 through the infrared rays, and judges whether liquid appears in the detection area 121 through the infrared detection signal. The second way is to set a shooting assembly, and directly judge whether liquid appears in the visual window 12 in the photo based on the photo of the visual window 12 taken by the shooting assembly.

[0065] In the above-mentioned steaming oven, the cooking shell 10, the heating assembly 20 for heating the cavity air in the cooking cavity 11, the temperature sensing assembly 30 for detecting the cavity temperature in the cooking cavity 11, the steam generator 40, the fan 50, and the controller 60 for controlling the steam generator 40 to generate steam when the cavity temperature reaches the water vaporization temperature, and for controlling the fan 50 to output air flow to the visual window 12 when liquid appears on the visual window 12 are arranged. The controller 60 is connected to the heating assembly 20, the temperature sensing assembly 30, the steam generator 40, and the fan 50. The cooking shell 10 has a cooking cavity 11 for placing food to be processed. The heating assembly 20, the temperature sensing assembly 30, the steam generator 40, and the fan 50 are arranged in the cooking cavity 11. The cooking shell 10 includes a visual window 12. Using the above-mentioned steaming oven to cook food, the cavity temperature in the cooking cavity 11 can be heated to the water vaporization temperature before the steam generator 40 in the steaming oven generates steam, which can ensure that the temperature of the steam will not decrease when it encounters cold, so that the steam will not condense into liquid water when it encounters cold, and the liquid on the visual window 12 is avoided. In addition, the fan 50 can be arranged, and the fan 50 can be controlled to output air flow to the visual window 12 even if liquid appears on the visual window 12. Therefore, using the above-mentioned steaming oven can double-protect the clarity of the shooting of the cooked food from two aspects of the steam temperature and the air flow output of the fan 50.

[0066] In one embodiment, the visual window 12 is divided into a plurality of detection areas 121, and each detection area 121 is provided with a corresponding infrared detection assembly 70; each infrared detection assembly 70 is connected to the controller 60.

[0067] The controller 60 is configured to control the infrared detection assembly 70 to emit infrared rays; the infrared rays are used to determine the infrared detection signal of the corresponding detection area 121 of the visual window 12; and the infrared detection signal is used to determine whether liquid appears in the detection area 121.

[0068] In this embodiment, the visual window 12 is divided into a plurality of detection areas 121, and the detection area 121 can be of various shapes, for example, the detection area 121 can be a rectangle of the same size, the length of the detection area 121 can be the same as the length of the bottom edge of the visual window 12, and the plurality of detection areas 121 are arranged from top to bottom. The infrared detection assembly 70 is a sensor assembly based on the principle of infrared detection. Because the emitted infrared rays are affected differently after passing through different objects, the final infrared detection signal is also different, so different objects can be detected through the emission and reception process of infrared rays. The infrared detection signal refers to the signal received when non-contact detection is performed using the infrared radiation or reflected infrared signal emitted by an object.

[0069] Specifically, the controller 60 can control the infrared detection assembly 70 of each detection area 121 to emit infrared rays, determine whether liquid appears in the detection area 121 according to the obtained infrared detection signal, and thus ensure that the liquid appearing on the visual window 12 can be processed in time.

[0070] In one embodiment, the infrared detection assembly 70 includes an infrared emission unit 71 and an infrared receiving unit 72; the infrared emission unit 71 is arranged on one side of the detection area 121; the infrared receiving unit 72 is arranged on the other side of the detection area 121; and the infrared emission unit 71 and the infrared receiving unit 72 are both connected to the controller 60.

[0071] The controller 60 is configured to control the infrared emission unit 71 to emit infrared rays; the infrared rays pass through the corresponding detection area 121 of the visual window 12 and reach the infrared receiving unit 72.

[0072] The controller 60 is configured to obtain the infrared detection signal received by the infrared receiving unit 72, and determine whether liquid appears in the corresponding detection area 121 of the visual window 12 based on the infrared detection signal.

[0073] The infrared emission unit 71 can be used to emit infrared rays, and the infrared receiving unit 72 can be used to receive infrared rays. The infrared emission unit 71 is arranged on one side of the detection area 121, and the infrared receiving unit 72 is arranged on the other side of the detection area 121. The infrared rays emitted by the infrared emission unit 71 sweep through the corresponding detection area 121 of the visible window and reach the infrared receiving unit 72, so that the presence of liquid in the corresponding detection area 121 can be detected. It can be understood that the transmission path of the infrared rays is parallel to the corresponding detection area 121 of the visible window, and the distance between the transmission path and the corresponding detection area 121 is less than or equal to a predetermined distance threshold, so as to ensure that when liquid appears in the corresponding monitoring area 121, the transmission path of the infrared rays will pass through the liquid.

[0074] Specifically, the controller 60 controls the infrared emission unit 71 to emit infrared rays, and the emitted infrared rays sweep through the corresponding detection area 121 of the visible window 12 and then reach the infrared receiving unit 72. The infrared receiving unit 72 receives the infrared rays, and the controller 60 obtains the infrared detection signal received by the infrared receiving unit 72. Based on the infrared detection signal, it can be determined whether liquid appears in the corresponding detection area 121 of the visible window 12. For example, if the infrared detection signal obtained by the controller 60 meets the standard of the standard detection signal, it means that the infrared rays do not pass through the liquid when they sweep through the corresponding detection area 121 of the visible window 12, that is, no liquid appears in the corresponding detection area 121 of the visible window 12.

[0075] In this embodiment, the infrared detection assembly 70 includes the infrared emission unit 71 and the infrared receiving unit 72. Based on the emission and reception of infrared rays, the presence of liquid in the visible window 12 can be better detected.

[0076] In one embodiment, the steam oven further includes a driving assembly 80; the driving assembly 80 is connected with the controller 60 and the fan 50.

[0077] The driving assembly 80 is used to drive the air outlet of the fan 50 to move under the control of the controller 60, so as to change the output direction of the airflow.

[0078] The driving assembly 80 refers to a component that can drive other components or modules to move. The air outlet of the fan 50 is the place where the fan 50 outputs air volume. After the airflow in the fan 50 is compressed or accelerated, it is discharged to the outside environment or a specified area through a specific channel. The output direction of the airflow can change with the change of the air outlet.

[0079] Specifically, the steam oven further includes a driving assembly 80, which is connected with the controller 60 and the fan 50. The controller 60 can control the driving assembly 80 to move, so as to drive the air outlet of the fan 50 to move. When the air outlet moves, the output direction of the airflow will change.

[0080] In this embodiment, the controller 60 controls the outlet of the fan 50 to move based on the driving assembly 80, so as to change the output direction of the air flow, thereby improving the flexibility of the air flow output by the fan 50.

[0081] Based on the same inventive concept, as Figure 5 As shown in the figure, the application also provides a filter screen dust removal method applied to the above-mentioned steam oven, which is taken as an example to illustrate the controller applied to the above-mentioned filter screen dust removal device, and the method comprises the following steps:

[0082] Step S502: controlling the heating assembly to heat the air in the cooking cavity.

[0083] The cooking cavity is used for placing food and is located in the cooking shell of the steam oven. The heating assembly is arranged in the cooking cavity.

[0084] Specifically, after the user places food in the steam oven and turns on the steam baking mode, the heating assembly can be controlled to work first to release heat, so as to heat the air in the cooking cavity.

[0085] Step S504: acquiring the temperature in the cooking cavity detected by the temperature sensing assembly.

[0086] The temperature in the cavity is the temperature in the cooking cavity. The temperature sensing assembly is arranged in the cooking cavity.

[0087] Specifically, after the heating assembly heats the air in the cooking cavity, the temperature in the cooking cavity will rise, and the controller needs to acquire the temperature in the cooking cavity detected by the temperature sensing assembly to determine the temperature in the cooking cavity.

[0088] Step S506: controlling the steam generator to generate steam in the case that the temperature in the cavity reaches the vaporization temperature of water.

[0089] The steam generator is arranged in the cooking cavity.

[0090] Specifically, if the temperature in the cavity reaches the vaporization temperature of water, the water in the cooking cavity will vaporize into gas, and therefore, the steam generator can be controlled to generate steam.

[0091] Step S508: controlling the fan to output air flow to the visible window of the cooking shell when liquid appears on the visible window.

[0092] The fan is arranged in the cooking cavity.

[0093] Specifically, in order to ensure the shooting clarity again, the fan can also be controlled to output air flow to the visible window when liquid appears on the visible window, so as to aggregate small liquid into large liquid and blow it to the bottom of the cooking cavity.

[0094] For example, the manner of determining the presence of liquid on the visual window can include two kinds: one is that a plurality of detection areas can be arranged on the visual window, and each detection area is provided with a corresponding infrared detection assembly. Each infrared detection assembly is connected to the controller, and the infrared detection assembly is controlled by the controller to emit infrared rays. The infrared detection signal of the corresponding detection area of the visual window is determined by the infrared rays, and it is determined whether liquid appears in the detection area by the infrared detection signal. The second is that a shooting assembly can be arranged. Based on the photo taken by the shooting assembly on the visual window, it is directly determined whether liquid appears in the visual window in the photo.

[0095] In a specific embodiment, in the case that liquid appears in the detection area, the fan speed matched with the infrared detection signal can be determined. According to the position of the detection area on the visual window, the outlet orientation of the fan is determined. According to the fan speed and the outlet orientation, the fan is controlled to output airflow to the detection area.

[0096] In another specific embodiment, in the case that at least two target detection areas appear liquid in each detection area, the priority of each target detection area is determined according to the infrared detection signal of each target detection area. According to the position of each target detection area on the visual window, the outlet orientation of the fan corresponding to each target detection area is determined. According to the order represented by the priority, the outlet orientation of the fan is adjusted, and the airflow is output to each target detection area in turn.

[0097] In the above-mentioned steam oven control method, the temperature in the cavity in the cooking cavity can be heated to the vaporization temperature of water before the steam generator in the steam oven generates steam. It is ensured that the temperature of the steam will not be lowered when it encounters cold, so as to ensure that the steam will not condense into liquid water when it encounters cold, avoid the appearance of liquid on the visual window, and also output airflow to the visual window through the fan to blow off the liquid. Therefore, by using the above-mentioned steam oven control method, the clarity of the photographed cooking food can be double-protected from the aspects of ensuring the steam temperature and the fan airflow output.

[0098] In one embodiment, the visual window is divided into a plurality of detection areas, and each detection area is provided with a corresponding infrared emission unit and an infrared receiving unit. In the case of this embodiment, as shown in Figure 6 The steam oven control method further includes:

[0099] Step S602: controlling the infrared emission unit arranged in the detection area to emit infrared rays.

[0100] Step S604: obtaining the infrared detection signal received by the infrared receiving unit, and determining whether liquid appears in the detection area based on the infrared detection signal.

[0101] The infrared emission unit can be configured to emit infrared rays, and the infrared receiving unit can be configured to receive infrared rays. The infrared emission unit is arranged on one side of the detection area, and the infrared receiving unit is arranged on the other side of the detection area. The infrared rays emitted by the infrared emission unit sweep through the corresponding detection area of the visible window and reach the infrared receiving unit, so that the presence of liquid in the corresponding detection area can be detected.

[0102] Specifically, the controller controls the infrared emission unit to emit infrared rays, and the emitted infrared rays sweep through the corresponding detection area of the visible window and reach the infrared receiving unit. The controller obtains the infrared detection signal received by the infrared receiving unit, and determines whether liquid appears in the corresponding detection area of the visible window based on the infrared detection signal. For example, if the infrared detection signal obtained by the controller meets the standard of the standard detection signal, it means that the infrared rays do not pass through the liquid when they sweep through the corresponding detection area of the visible window, i.e., no liquid appears in the corresponding detection area of the visible window.

[0103] In this embodiment, the infrared detection assembly includes an infrared emission unit and an infrared receiving unit, which can better detect the presence of liquid in the visible window based on the emission and reception of infrared rays.

[0104] In one embodiment, as shown in Figure 7 When liquid appears on the visible window of the cooking shell, the controller controls the fan to output air flow to the visible window, including:

[0105] Step S702, determining the fan speed matched with the infrared detection signal when liquid appears in the detection area.

[0106] Step S704, determining the orientation of the air outlet of the fan according to the position of the detection area on the visible window.

[0107] Step S706, controlling the fan to output air flow to the detection area according to the fan speed and the orientation of the air outlet.

[0108] The fan speed refers to the number of rotations per minute of the fan. The greater the fan speed, the stronger the air flow output by the fan.

[0109] Specifically, the strength of the infrared detection signal varies depending on the object in the infrared emission path. The presence of liquid in the path results in a weaker signal than when no liquid is present. Therefore, if liquid is present in one of the detection areas of the viewing window, the corresponding fan speed can be determined based on the infrared detection signal for that area. Furthermore, the fan's outlet orientation can be determined based on the location of the detection area within the viewing window. The fan is then controlled to output airflow to the detection area according to both the fan speed and the outlet orientation. In other words, a weaker infrared detection signal in the detection area corresponds to a stronger fan speed.

[0110] In this embodiment, if liquid appears in the detection area, the corresponding fan speed can be matched according to the infrared detection signal to output airflow to the detection area, which can remove the liquid in the detection area in time and ensure the clarity of the viewing window.

[0111] In one embodiment, such as Figure 8 As shown, when liquid appears on the viewing window of the cooking shell, the fan is controlled to output airflow to the viewing window, including:

[0112] Step S802: When liquid is present in at least two target detection areas in each detection area, the priority of each target detection area is determined based on the infrared detection signal of each target detection area.

[0113] Step S804: Determine the direction of the air outlet of the fan corresponding to each target detection area based on the position of each target detection area on the viewing window.

[0114] Step S806: Adjust the direction of the fan outlet according to the priority order, and output airflow to each target detection area in sequence.

[0115] The target detection area refers to the detection area that meets specific conditions. Priority is essentially a convention or rule used to determine the order in which different tasks, activities, or requirements are processed.

[0116] Specifically, if liquid appears in multiple detection areas, the fan can be controlled to output air flow to the detection areas with more liquid first, that is, if liquid appears in at least two target detection areas, the priority of each target detection area can be determined according to the infrared detection signal of each target detection area, so as to determine the amount of liquid in each target detection area, then the position of each target detection area on the visible window is determined, the outlet orientation of the fan corresponding to each target detection area is determined, and finally the outlet orientation of the fan is adjusted according to the order represented by the priority, and air flow is output to each target detection area in turn.

[0117] Optionally, the fan can output air flow to each target detection area in turn according to the order represented by the priority, and after the liquid in the target detection area with the highest priority is removed, air flow is output to the target detection area with the next highest priority.

[0118] Optionally, the fan can output air flow to each target detection area in turn according to the order represented by the priority, and after the liquid in the target detection area with the highest priority is removed, air flow is output to the target detection area with the next highest priority.

[0119] In this embodiment, when liquid appears in multiple detection areas, the priority of the fan outputting air flow is determined according to the infrared detection signal, and air flow is output according to the priority, so that air flow can be output to the detection area with more liquid first, ensuring that the visible window has high clarity.

[0120] In one specific embodiment, as shown in Figure 9 A steam oven is also provided, which includes a cooking shell, a heating assembly, a temperature sensing assembly, a fan, a cooking cavity, a visible window, an infrared emitting unit and an infrared receiving unit, wherein the fan is located at the top of the inner cavity of the steam oven, near the upper side of the visible window.

[0121] When the user uses the steam mode, the steam generator is not immediately started to generate steam, but the heating tube is first started to raise the temperature in the cavity of the steam oven to the temperature required for water vaporization, and then the steam generator is started to generate steam into the cavity of the steam oven. At this time, the temperature in the cavity has reached the vaporization temperature of water, and the steam generated by the steam generator in the cavity will not condense into liquid water.

[0122] The function of the fan located at the top of the inner cavity of the steaming oven: 1. The fan is located above the viewing window. If some condensate water is generated due to external environmental interference, the fan can blow the water droplets on the inner wall of the viewing window down to the bottom plate from top to bottom, ensuring that there is no water mist blocking. 2. The fan can blow the heat at the top of the inner cavity of the steaming oven to the inner wall of the viewing window, preventing condensate water from appearing on the inner wall, and at the same time, heating and drying the glass inner wall to remove water mist, keeping the viewing window dry, free of water mist, and having high visibility, ensuring that cooking video recording, photo shooting, and other operations can be performed in the steaming mode, and improving user experience.

[0123] The steaming oven control method includes: N groups of infrared emission units and infrared receiving units (denoted as A1-An) are arranged on the left and right sides of the viewing window, the respective infrared detection assemblies are arranged in order from top to bottom, and the distance between each group of infrared detection assemblies is d. The condensate water occurrence in different detection areas of the viewing window is detected by multiple groups of infrared detection assemblies, and then the angle of the fan is adjusted to accurately point to different areas. The positions of the two are on the same horizontal line as the inside of the transparent viewing window glass. The function is: when the steam generator starts to generate steam, the infrared emission unit and the infrared receiving unit are turned on. If condensate water appears on the inside of the viewing window, the refraction of liquid water to light will affect the infrared light reception rate Y. In this way, it is judged whether condensate water appears on the glass inner wall, so as to control the speed S of the top fan. The speed is adaptively adjusted according to the detected water mist. The relationship between the two is: S=kY+B, where k<0, B>0, and 0Y<1 (i.e. when the infrared light reception rate Y approaches 100%, the fan speed S approaches 0; when the infrared light reception rate Y approaches 0%, the fan speed S approaches the maximum value Smax).

[0124] The angle α (0°<α<90°) of the fan blowing towards the viewing window depends on the reception rate Y detected by the infrared detection assemblies in different areas. The priority of the fan automatically adjusting the angle is A1>A2>A3>....>An (i.e. the fan blows towards the area above the viewing glass first, from top to bottom).

[0142] Step S1107, control the fan to output airflow to the detection area according to the rotation speed of the fan and the orientation of the air outlet.
