[0055] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

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

[0057] A steam oven is a kitchen appliance that combines steaming, cooking and baking functions. It mainly relies on a built-in steam generator and heating element to cook food. A steam oven combines multiple cooking methods such as steaming, baking, stewing and boiling. One machine can meet different cooking needs, save kitchen space and make the kitchen tidier. Cooking with high-temperature steam can better retain the nutrients of food and make 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 so as to share them on various short video platforms or WeChat Moments. However, when using the steaming mode of an existing steam oven to cook food, condensed liquid water droplets will form on the visible window of the steam oven, blocking the camera, causing the photos or videos to be blurry.

[0059] Based on this, Figure 1 As shown, the present application provides a steam oven, comprising: a cooking shell 10, a heating component 20, a temperature sensing component 30, a steam generator 40, a fan 50, and a controller 60; the controller 60 is connected to the heating component 20, the temperature sensing component 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 component 20, the temperature sensing component 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 component 20 is used to heat the air in the cooking cavity 11; the temperature sensing component 30 is used to detect the cavity temperature of the cooking cavity 11; the controller 60 is used to control the steam generator 40 to generate steam when the cavity temperature reaches the vaporization temperature of water; the controller 60 is also used to control the fan 50 to output airflow 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 wraps, covers or protects food or cooking utensils during the cooking process. Specifically, the cooking shell 10 refers to the external structure of the cooking utensil (such as a rice cooker, oven, microwave oven, etc.), which is usually made of metal, plastic or other heat-resistant materials to protect the internal mechanism and components, while providing an aesthetic appearance and an easy-to-clean surface. The heating component 20, also known as an electric heating element or a heating component, is a device that converts electrical energy into thermal energy. In the present application, the heating component 20 can be, for example, a heating tube, which is used to dissipate heat to heat the air in the cooking cavity 11. The heating tube, also known as an electric heating tube or an electric heating tube, is an electric heating element that converts electrical energy into thermal energy based on the principle that Joule heat is generated when current passes through a conductor. The temperature sensing component 30, also known as a temperature sensitive element or a temperature sensor, is a device that can sense temperature and convert it into a measurable or identifiable signal. Specifically, the temperature sensing component 30 can convert the temperature signal into an electrical signal or other identifiable signal by using the principles of the material's thermoelectric effect, resistance effect, thermistor effect, thermal resistor effect, thermocouple effect, etc. For example, the temperature sensing component 30 can be a temperature sensing package or a temperature sensor.

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

[0062] The fan 50 is a mechanical device for sucking, discharging or compressing gas, and is a machine that converts the mechanical energy of the prime mover into gas energy. It is a device that relies on the input mechanical energy to increase the gas pressure and discharge the gas. The working principle of the fan 50 is mainly to use the rotation of the blades on the wind wheel to promote the flow of air. When the fan 50 starts working, the blades will suck the surrounding air into the fan 50, and then increase the speed of the wind wheel through the coordinated action of the bearings, motors and reducers, so as to blow the air out of the fan 50. The driving force of the fan 50 comes from the horizontal thrust and vertical thrust on the blades. The controller 60 refers to a master command device that can receive and process signals. It is a "decision-making body" that issues commands and can coordinate and command the operation of the entire system or equipment. The working principle of the controller 60 is to receive signals from sensors or other input devices, judge and process them according to a predetermined program or logic, and then output corresponding control signals to achieve control of the equipment or system.

[0063] The cooking cavity 11 is a key component of the cooking device, which provides a closed or semi-closed space for accommodating food and performing the cooking process. The cooking cavity 11 is a space inside the cooking device (such as an oven, a steam oven, a microwave oven, etc.), and its main function is to accommodate food and cook the food thoroughly by heating, steaming or other cooking methods. In the present application, the cooking shell 10 has a cooking cavity 11 for placing the food to be processed, that is, the cooking shell 10 contains the cooking cavity 11, and the inner wall of the cooking shell 10 and the cooking cavity 11 can be fitted or there can be a gap. The visual window 12 refers to a window that can be seen from one side of the window to the other side. For example, the visual window 12 can be made of transparent glass, and the user who cooks food can clearly see the cooking status of the food inside the steam oven through the visual window 12. The vaporization temperature of water, also known as the saturation temperature or boiling point, is the temperature when water changes from liquid to gas (i.e. vaporizes or boils). This temperature is directly related to the external pressure of the 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. Take water as an example. Under standard atmospheric pressure (101.325kPa), the vaporization temperature of water is 100°C.

[0064] Specifically, after the user places food in the steam oven and turns on the steam-bake mode, the air in the cooking cavity 11 needs to be heated by the heating component 20 first, and the cavity temperature of the cooking cavity 11 needs to be detected by the temperature sensing component 30. When the cavity temperature reaches the vaporization temperature of water, it can be ensured that the temperature of the steam will not drop when it is cold, thereby ensuring that the steam will not condense into liquid water when it is cold, thereby avoiding the appearance of liquid on the visible window 12. Therefore, the controller 60 can control the steam generator 40 to generate steam, thereby avoiding the steam from encountering the inner wall of the cooking cavity 11 with a lower temperature and condensing into liquid water droplets. In order to provide a secondary guarantee for the shooting clarity, when liquid appears on the visible window 12, the fan 50 can be controlled to output airflow to the visible window 12 to aggregate smaller liquids into larger liquids and blow them to the bottom of the cooking cavity 11. Exemplarily, there are two ways to determine whether liquid appears on the visible window 12: First, a plurality of detection areas 121 may be set in the visible window 12, and a corresponding infrared detection component 70 may be set in each detection area 121, and each infrared detection component 70 is connected to the controller 60, and the controller 60 controls the infrared detection component 70 to emit infrared rays, and the infrared detection signal of the corresponding detection area 121 of the visible window 12 is determined by infrared rays, and whether liquid appears in the detection area 121 is determined by the infrared detection signal. Second, a shooting component may be set, and based on the photos taken by the shooting component of the visible window 12, it is directly determined whether liquid appears in the visible window 12 in the photo.

[0065] The steam oven is provided with a cooking shell 10, a cavity air heating component 20 for heating a cooking cavity 11, a cavity temperature sensing component 30 for detecting the cavity temperature of the cooking cavity 11, a steam generator 40, a fan 50, and a controller 60 for controlling the steam generator 40 to generate steam when the cavity temperature reaches the vaporization temperature of water, and for controlling the fan 50 to output airflow to the visual window 12 when liquid appears on the visual window 12; wherein the controller 60 is connected to the heating component 20, the temperature sensing component 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 component 20, the temperature sensing component 30, the steam generator 40 and the fan 50 are all arranged in the cooking cavity 11; the cooking shell 10 includes a visual window 12. When cooking food with the steam oven, the temperature in the cooking cavity 11 can be heated to the vaporization temperature of water before the steam generator 40 in the steam oven generates steam, so that the temperature of the steam will not be lowered when it is cooled, thereby ensuring that the steam will not condense into liquid water when it is cooled, and avoiding the appearance of liquid on the visual window 12. In addition, a fan 50 can be provided, and even if liquid appears on the visual window 12, the fan 50 can be controlled to output airflow to the visual window 12. Therefore, with the steam oven, the clarity of the cooked food can be double-protected from the two aspects of ensuring the steam temperature and the airflow 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 respectively provided with a corresponding infrared detection component 70; each infrared detection component 70 is connected to the controller 60;

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

[0068] Among them, the detection area 121 refers to the area used to detect whether liquid is present. In this embodiment, a plurality of detection areas 121 are provided in the visual window 12. The detection areas 121 can be of various shapes. For example, the detection areas 121 can be rectangles of the same size. The length of the detection area 121 can be set to the same length as the bottom edge of the visual window 12. The plurality of detection areas 121 are arranged from top to bottom. The infrared detection component 70 is a sensor component based on the infrared detection principle. Since the emitted infrared rays are blocked to different degrees after passing through different objects, the infrared detection signals finally obtained are also different. Therefore, different objects can be detected through the infrared emission and reception process. The infrared detection signal refers to the signal received when non-contact detection is performed using the infrared radiation emitted by the object or the reflected infrared signal.

[0069] Specifically, the controller 60 can control the infrared detection components 70 of each detection area 121 to emit infrared rays, and determine whether liquid appears in the detection area 121 based on the obtained infrared detection signal, thereby ensuring that the liquid appearing on the visible window 12 can be promptly processed in the future.

[0070] In one embodiment, the infrared detection component 70 includes an infrared emitting unit 71 and an infrared receiving unit 722; the infrared emitting unit 71 is disposed on one side of the detection area 121; the infrared receiving unit 72 is disposed on the other side of the detection area 121; the infrared emitting unit 71 and the infrared receiving unit 72 are both connected to the controller 60;

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

[0072] The controller 60 is used 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 visible window 12 based on the infrared detection signal.

[0073] Among them, the infrared emitting unit 71 can be used to emit infrared rays, and the infrared receiving unit 72 can be used to receive infrared rays. The infrared emitting 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 emitting unit 71 pass through the corresponding detection area 121 and reach the infrared receiving unit 72, so as to detect the presence of liquid in the corresponding detection area 121. It can be understood that the transmission path of the infrared rays is parallel to the corresponding detection area 121 of the visual window, and the distance between the transmission path and the corresponding detection area 121 is less than or equal to the preset 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 emitting unit 71 to emit infrared rays, and the emitted infrared rays pass through the corresponding detection area 121 of the visible window 12, and then reach the infrared receiving unit 72, and are received by the infrared receiving unit 72. The controller 60 obtains the infrared detection signal received by the infrared receiving unit 72, and based on the infrared detection signal, it can determine whether liquid appears in the corresponding detection area 121 of the visible window 12. For example, the infrared detection signal obtained by the controller 60 meets the standard of the standard detection signal, which means that when the infrared rays pass through the corresponding detection area 121 of the visible window 12, they do not pass through the liquid, that is, no liquid appears in the corresponding detection area 121 of the visible window 12.

[0075] In this embodiment, the infrared detection component 70 includes an infrared emitting unit 71 and an infrared receiving unit 72 , which can better detect the presence of liquid in the visible window 12 based on the process of emitting and receiving infrared rays.

[0076] In one embodiment, the steam oven further includes a driving assembly 80; the driving assembly 80 is connected to 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 to change the output direction of the airflow.

[0078] The drive component 80 refers to a component that can drive other components and modules to move. The air outlet of the fan 50 is where the fan 50 outputs the air volume. It is the outlet where the airflow inside the fan 50 is compressed or accelerated and discharged to the external environment or a designated 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 also includes a driving component 80, which is connected to the controller 60 and the fan 50. The controller 60 can control the movement of the driving component 80 to drive the air outlet of the fan 50 to move. When the air outlet moves, the output direction of the airflow will change accordingly.

[0080] In this embodiment, the controller 60 controls the movement of the air outlet of the fan 50 based on the driving component 80, thereby changing the output direction of the airflow, which can improve the flexibility of the airflow output by the fan 50.

[0081] Based on the same inventive concept, Figure 5 As shown, the embodiment of the present application also provides a filter dust removal method applied to the above steam oven, and the method is described by taking the controller in the above filter dust removal device as an example. The method includes the following steps:

[0082] Step S502, controlling the heating component 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 components are all arranged in the cooking cavity.

[0084] Specifically, after the user places food into the steam oven and turns on the steaming mode, the heating component can be controlled to work and emit heat, thereby heating the air in the cooking cavity.

[0085] Step S504, obtaining the cavity temperature of the cooking cavity detected by the temperature sensing component.

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

[0087] Specifically, after the heating component heats the air in the cooking cavity, the cavity temperature of the cooking cavity will increase accordingly. The controller needs to obtain the cavity temperature of the cooking cavity detected by the temperature sensing component to determine the temperature condition in the cooking cavity.

[0088] Step S506, when the temperature in the cavity reaches the vaporization temperature of water, controlling the steam generator to generate steam.

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

[0090] Specifically, if the temperature in the cavity reaches the vaporization temperature of water, it indicates that water exists in the cooking cavity, and the water will be vaporized into gas. Therefore, the steam generator can be controlled to generate steam.

[0091] Step S508: When liquid appears on the visible window of the cooking shell, the fan is controlled to output airflow to the visible window.

[0092] Wherein, the fan is arranged in the cooking cavity.

[0093] Specifically, in order to provide a secondary guarantee for the clarity of the shooting, when liquid appears on the visible window, the fan can be controlled to output airflow to the visible window, so as to aggregate smaller liquids into larger liquids and blow them to the bottom of the cooking cavity.

[0094] Exemplarily, there are two ways to determine whether liquid appears on the visible window: first, multiple detection areas can be set in the visible window, and each detection area is respectively provided with a corresponding infrared detection component, and each infrared detection component is connected to a controller, and the controller controls the infrared detection component to emit infrared rays, and the infrared detection signal of the corresponding detection area of ​​the visible window is determined by infrared rays, and whether liquid appears in the detection area is determined by the infrared detection signal. Second, a shooting component can be set, and based on the photos taken by the shooting component of the visible window, it can be directly determined whether liquid appears in the visible window in the photo.

[0095] In a specific embodiment, when liquid appears in the detection area, the fan speed that matches the infrared detection signal can be determined, and the direction of the fan outlet can be determined according to the position of the detection area on the visible window. According to the fan speed and the direction of the air outlet, the fan is controlled to output airflow to the detection area.

[0096] In another specific embodiment, when there are liquids in at least two target detection areas in each detection area, the priority of each target detection area is determined according to the infrared detection signal of each target detection area, and the direction of the air outlet of the fan corresponding to each target detection area is determined according to the position of each target detection area on the visual window. The direction of the air outlet of the fan is adjusted in the order represented by the priority to output airflow to each target detection area in turn.

[0097] In the above steam oven control method, before the steam generator in the steam oven generates steam, the temperature in the cooking cavity can be heated to the vaporization temperature of water to ensure that the temperature of the steam will not drop when it is cooled, thereby ensuring that the steam will not condense into liquid water when it is cooled, thereby avoiding the appearance of liquid on the visual window, and the fan can also output airflow to the visual window to blow the liquid off. Therefore, by adopting the above steam oven control method, the clarity of shooting cooking food can be doubly guaranteed from the two 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 respectively provided with a corresponding infrared transmitting unit and an infrared receiving unit. Figure 6 As shown, the steam oven control method also includes:

[0099] Step S602, controlling the infrared emitting unit set in the detection area to emit infrared rays.

[0100] Step S604, acquiring 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] Among them, the infrared transmitting unit can be used to transmit infrared rays, and the infrared receiving unit can be used to receive infrared rays. The infrared transmitting unit is set on one side of the detection area, and the infrared receiving unit is set on the other side of the detection area. The infrared rays emitted by the infrared transmitting unit pass through the corresponding detection area and reach the infrared receiving unit, so as to detect the presence of liquid in the corresponding detection area.

[0102] Specifically, the controller controls the infrared emitting unit to emit infrared rays, and the emitted infrared rays pass through the corresponding detection area of ​​the visible window, and then reach the infrared receiving unit, and are received by 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, the infrared detection signal obtained by the controller meets the standard of the standard detection signal, which means that when the infrared rays pass through the corresponding detection area of ​​the visible window, they do not pass through the liquid, that is, no liquid appears in the corresponding detection area of ​​the visible window.

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

[0104] In one embodiment, Figure 7 As shown, when liquid appears on the visible window of the cooking housing, the fan is controlled to output airflow to the visible window, including:

[0105] Step S702: when liquid appears in the detection area, determine the fan speed that matches the infrared detection signal.

[0106] Step S704, determining the direction 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 airflow to the detection area according to the fan speed and the air outlet direction.

[0108] Among them, the fan speed refers to the number of times the fan rotates per minute. The greater the fan speed, the stronger the airflow output by the fan.

[0109] Specifically, the strength of the infrared detection signal will be different for different objects on the infrared emission path. If there is liquid in the infrared emission path, the infrared detection signal will be weaker than the infrared detection signal when there is no liquid on the infrared emission path. Therefore, if liquid appears in one of the detection areas of the visual window, the corresponding fan speed can be determined based on the infrared detection signal of the detection area, and the direction of the fan outlet can be determined based on the position of the detection area on the visual window. According to the fan speed and the direction of the outlet, the fan is controlled to output airflow to the detection area. It can be understood that if the infrared detection signal on the detection area is relatively weak, the fan speed matching the infrared detection signal is relatively strong.

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

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

[0112] Step S802, when there are at least two target detection areas in each detection area with liquid present, determining the priority of each target detection area according to the infrared detection signals of each target detection area;

[0113] Step S804, determining the directions of the air outlets of the fans corresponding to the respective target detection areas according to the respective positions of the target detection areas on the visual window;

[0114] Step S806, adjusting the direction of the air outlet of the fan in the order represented by the priority, and outputting airflow to each target detection area in turn.

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

[0116] Specifically, if there are multiple detection areas in each detection area where liquid appears, the fan can be controlled according to the amount of liquid appearing, and airflow can be output to the detection areas with more liquid appearing preferentially. That is, when there are at least two target detection areas in each detection area where liquid appears, the priority of each target detection area can be determined according to the infrared detection signal of each target detection area, thereby determining the amount of liquid appearing in each target detection area, and then determining the direction of the fan's air outlet corresponding to each target detection area according to the position of each target detection area on the visible window, and finally adjusting the direction of the fan's air outlet in the order represented by the priority to output airflow to each target detection area in turn.

[0117] Optionally, the fan may output airflow to each target detection area in sequence according to the order represented by the priority, and after removing the liquid in the target detection area with the highest priority, output airflow to the target detection area with the next highest priority.

[0118] Optionally, the fan can output airflow to each target detection area in sequence according to a preset output duration of each output airflow and in an order represented by the priority, and output airflow to each target detection area in multiple cycles until all the liquid in each target detection area is blown away.

[0119] In this embodiment, when liquid appears in multiple detection areas, the priority of the fan output airflow is determined based on the infrared detection signal, and the airflow is output according to the priority. The airflow can be output to the detection area with more liquid first to ensure that the visible window has a higher clarity.

[0120] In a specific embodiment, Fig. 9 As shown, a steam oven is also provided, comprising: a cooking shell, a heating component, a temperature sensing component, a fan, a cooking cavity, a visual window, an infrared transmitting 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 inner side of the visual window.

[0121] When the user uses the steaming mode, the steam generator will not be turned on immediately to generate steam. Instead, the heating tube will be turned on first to raise the temperature inside the oven cavity to the temperature required for water vaporization. Then the steam generator will be turned on to start generating steam into the oven cavity. At this time, the temperature inside the cavity has reached the vaporization temperature of water, and the steam generated by the steam generator into the cavity will not condense into liquid water.

[0122] The function of the fan located at the top of the steam oven cavity: 1. The fan is located above the visual window. If some condensation water is generated due to external environmental interference, the wind force of the fan from top to bottom can blow the water droplets on the inner wall of the visual window down to the chassis to ensure that there is no water mist blocking it. 2. The fan can blow the heat from the top of the steam oven cavity to the inner wall of the visual window to prevent condensation water from appearing on the inner wall. At the same time, it can heat and dry the inner wall of the glass to remove the water mist, keep the visual window dry and free of water mist, and ensure clear visibility, so as to ensure that cooking video recording, photo shooting and other operations can be performed in steaming mode, and improve user experience.

[0123] The steam oven control method includes: N groups of infrared emitting units and infrared receiving units (denoted as A1~An) are arranged on the left and right sides of the visible window, and the respective infrared detection components are arranged in sequence from top to bottom, and the distance between each group of infrared detection components is d, and the appearance of condensed water in different detection areas of the visible window is detected by multiple groups of infrared detection components, so as to control the fan to adjust the angle accurately toward different areas. The positions of the two are located on the same horizontal line as the inner side of the transparent visible window glass. The function is: when the steam generator starts to generate steam, the infrared emitting unit and the infrared receiving unit are turned on. If condensed water appears on the inner side of the visible window, the refraction of light by liquid water will affect the infrared light receiving rate Y, so as to judge whether condensed water appears on the inner wall of the glass, so as to control the speed S of the top fan, and the speed is adaptively adjusted according to the detected water mist, and the relationship between the two is: S=kY+B, where k<0, B>0, 0<Y<1 (that is, when the infrared light receiving rate Y is close to 100%, the fan speed S approaches 0; when the infrared light receiving rate Y is close to 0%, the fan speed S approaches the maximum value Smax).

[0124] The angle α (0°<α<90°) at which the fan blows toward the visible window depends on the reception rate Y detected by the infrared detection components in different areas. The priority of the fan's automatic angle adjustment is A1>A2>A3>....>An (i.e., the fan preferentially blows toward the area above the visible window glass, from top to bottom).
