Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a range hood, control method, control device, and storage medium. Background Technology

[0002] Common kitchen appliances such as range hoods and integrated stoves have smoke extraction functions. Their smoke extraction principle is based on aerodynamics. The motor drives the impeller to rotate, which expels the air inside the volute and creates negative pressure. Atmospheric pressure then draws the air in the kitchen space, carrying the fumes, into the air inlet, and then exhausts the fumes outdoors through the duct and exhaust pipe.

[0003] The kitchen is a place for cooking food. Due to its small space, relatively poor air circulation, and the need for high temperatures from flames, the temperature inside the kitchen can be very high in the summer. Therefore, many modern families install air conditioners or cooling fans in their kitchens. They use range hoods to filter cooking fumes while cooking, and air conditioners or cooling fans help to cool down the kitchen environment during cooking, thus improving the user's cooking experience.

[0004] However, the problem is that when users feel the kitchen is too hot during cooking and want to turn on the air conditioner, cooling fan, or other cooling devices to cool it down, their hands are often wet, oily, or covered in cooking utensils, making it difficult for them to find and operate the air conditioner or cooling fan remote control, which causes inconvenience to users. Summary of the Invention

[0084] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0086] Figure 1 This is a front view showing the positional relationship between the first and second detection components. Figure 2 yes Figure 1 The shown is a side view of the structure in standby mode. Figure 3 This is a flowchart of a control method for a range hood provided in an embodiment of the present invention, such as... Figures 1-3 As shown, the range hood is used in conjunction with the cooling equipment;

[0087] The range hood includes an air guide plate 12, a first detection component 20, a second detection component 30, and a radar component (not shown in the figure); the first detection component 20 and the second detection component 30 are respectively located in the spaces on opposite sides of the air guide plate 12.

[0088] When the air guide plate 12 is in the closed state, the air guide plate 12 blocks the space between the second detection component 30 and the stove 200; when the air guide plate 12 is in the open state, the air guide plate 12 blocks the space between the first detection component 20 and the stove 200.

[0089] The control method includes:

[0090] In standby mode, the first detection component detects the first temperature of the stove, and the radar component detects the presence of people near the range hood.

[0091] Based on the initial temperature of the cooktop and the presence of people near the range hood, the system controls whether the range hood switches from standby to on and whether an alarm is triggered. In standby mode, the air guide plate is closed; in on mode, the air guide plate is open.

[0092] When the appliance is powered on, the second detection component 30 is used to detect the second temperature of the stove, the radar component is used to detect the presence of people near the range hood, and the first detection component is used to detect the ambient temperature of the range hood.

[0093] Based on the second temperature of the stove, control the working level of the range hood and whether the range hood switches from the on state to the standby state;

[0094] The operating status of the cooling equipment is controlled according to the number of people near the range hood and the ambient temperature.

[0095] like Figure 1 and Figure 2 As shown, the range hood also includes a smoke collection assembly 10; the air guide plate 12 is connected to the smoke collection assembly 10 and can switch between a closed state and an open state;

[0096] The first detection component 20 and the second detection component 30 are both disposed on the air guide plate 12 and are respectively located on the two opposite sides of the air guide plate 12; the detection area of ​​the first detection component 20 faces the outside of the air guide plate 12, and the detection area of ​​the second detection component 30 faces the inside of the air guide plate 12.

[0097] In the closed state, the air guide plate 12 is in the closed position, and the first detection component 20 can detect whether the stove 200 in the detection area is ignited; in the open state, the air guide plate 12 flips forward, and the second detection component 30 can detect whether the stove 200 in the detection area is turned off.

[0098] Specifically, in the closed state, since the detection area of ​​the first detection component 20 faces the outside of the guide vane 12, the guide vane 12 will not obstruct the first detection component 20 from detecting the stove 200. The first detection component 20 can detect whether the stove 200 is ignited. In the open state, the guide vane 12 flips forward so that the inner surface of the guide vane 12 faces the stove 200. Since the detection area of ​​the second detection component 30 faces the inside of the guide vane 12, the second detection component 30 can obtain whether the stove 200 in the detection area is turned off. Therefore, by the cooperation of the first detection component 20 and the second detection component 30, the state of the stove 200 in the detection area can be obtained in both the closed and open states, regardless of the flip angle of the guide vane 12, which improves the accuracy of temperature detection and takes into account both intelligent detection and a larger smoke collection chamber 101.

[0099] The first and second detection components can detect either the cooktop 200 or the cookware on the cooktop 200. When the air guide plate 12 is in the closed position, its outer surface faces the cooktop 200, thus facilitating the first detection component 20 to obtain the state of the cooktop 200 within the detection area. When the air guide plate 12 is in the open position, its inner surface faces the cooktop 200, thus facilitating the second detection component 20 to obtain the state of the cooktop 200 within the detection area. It should be noted that when the air guide plate 12 is in the open position, since its outer surface faces away from the cooktop 200, it can measure the temperature of the space where the range hood is located within the detection area, i.e., obtain the temperature of the environment where the range hood is located.

[0100] Specifically, based on the above structure, refer to Figures 1-3 The control method of this range hood includes:

[0101] S110. In standby mode, the first temperature of the stove is detected by the first detection component, and the situation of people near the range hood is detected by the radar component.

[0102] The first temperature refers to the temperature of the cooktop 200 detected by the first detection component 20 when the range hood is in standby mode. It can be understood that by detecting the temperature of the cooktop 200, the first detection component 20 can determine whether the user is cooking. Since the temperature near the cooktop 200 rises during cooking, and cooking inevitably produces fumes, temperature detection can determine the presence of fumes, thus further controlling the state of the range hood.

[0103] Specifically, in standby mode, when the air guide plate 12 is closed, the air guide plate 12 blocks the space between the second detection component 30 and the cooktop 200. At this time, the first detection component 20 detects the first temperature T1 of the cooktop 200, and the radar component detects whether there is anyone nearby, and then makes a further judgment on how to operate the range hood.

[0104] S120. Based on the first temperature of the stove and the situation of people near the range hood, control whether the range hood switches from standby mode to on mode and whether to issue an alarm.

[0105] Specifically, if the first temperature T1 of the cooktop 200 is equal to or higher than the preset temperature, and there are people present, the range hood will be switched from standby mode to on mode; if no one is detected, the range hood will remain in standby mode and start alarming, or switch to on mode and start alarming; if the detected temperature is lower than the preset temperature, the range hood will remain in standby mode.

[0106] For example, if the first detection component 20 detects a temperature below 50°C, the range hood will remain in standby mode; if the temperature is equal to or higher than 50°C, it will switch to the on-state. At this time, if the first detection component 20 detects a first temperature T1 of 60°C for the cooktop 200, which is higher than the preset temperature, and detects that no one is nearby, the range hood will switch from standby mode to on-state, begin absorbing cooking fumes, and issue an alarm.

[0107] S130. When the machine is powered on, the second detection component is used to detect the second temperature of the stove, the radar component is used to detect the situation of people near the range hood, and the first detection component is used to detect the ambient temperature of the range hood.

[0108] The second temperature is the temperature of the cooktop 200 detected by the second detection component 30 when the range hood is turned on.

[0109] Specifically, when the range hood is turned on and the air guide plate 12 is in the open state, the air guide plate 12 blocks the space between the first detection component 20 and the cooktop 200. At this time, the second detection component 30 starts to detect the second temperature T2 of the cooktop 200, the first detection component 20 starts to detect the ambient temperature T near the range hood, and the radar component detects whether there are people nearby, and then makes further judgments on how to operate the range hood.

[0110] S140. Based on the second temperature of the stove, control the working level of the range hood and whether the range hood switches from the on state to the standby state.

[0111] As those skilled in the art will know, a range hood can be set to multiple operating states to meet the user's needs for exhausting fumes generated in different cooking situations. For example, it can be set to multiple operating levels such as stir-fry, high, and low. It is understood that the operating power of the range hood is different under these three operating levels. The second detection component 30 detects the second temperature T2 of the stove 200 and compares it with the set temperature to determine the degree of fumes generated, and then controls the operating level and state of the range hood accordingly.

[0112] For example, if the second detection component 30 detects a temperature equal to or higher than 50°C, the range hood will remain on; if the temperature is below 50°C, it will switch to standby mode. However, if the second detection component 30 detects a second temperature T1 of 100°C for the cooktop 200, which is far higher than the set temperature, indicating that the user is cooking and producing a large amount of fumes, then the range hood will remain on and its operating mode will be adjusted to the high-power setting to increase the static pressure and filter a large amount of fumes.

[0113] S150: Control the working status of the cooling equipment according to the number of people near the range hood and the ambient temperature.

[0114] Specifically, a corresponding preset ambient temperature can be set for the ambient temperature T. The measured ambient temperature T is compared with the preset ambient temperature. If it is equal to or higher than the preset ambient temperature and someone is detected nearby, the cooling device will start cooling. If no one is detected nearby, the cooling device can start cooling or not cool and will start an alarm. If the ambient temperature T is lower than the preset ambient temperature, the cooling device will not work.

[0115] This invention provides a control method for a range hood, wherein the range hood is used in conjunction with a cooling device; the range hood includes an air guide plate, a first detection component, a second detection component, and a radar component; the first and second detection components are respectively located in opposite spaces on both sides of the air guide plate; when the air guide plate is in a closed state, it blocks the space between the second detection component and the cooktop; when the air guide plate is in an open state, it blocks the space between the first detection component and the cooktop; the control method includes: in a standby state, using the first detection component to detect a first temperature of the cooktop, and using the radar component to detect the temperature near the range hood. The system monitors the number of people near the range hood; based on the first temperature of the stove and the number of people near the range hood, it controls whether the range hood switches from standby mode to on mode and whether an alarm is triggered; when on mode, it uses a second detection component to detect the second temperature of the stove, a radar component to detect the number of people near the range hood, and a first detection component to detect the ambient temperature of the range hood; based on the second temperature of the stove, it controls the operating level of the range hood and whether it switches from on mode to standby mode; based on the number of people near the range hood and the ambient temperature, it controls the operating status of the cooling equipment. This control method uses a first and a second detection component to detect the stove temperature to determine if cooking is taking place, thereby controlling the range hood's on / off and standby states to filter cooking fumes and intelligently switching the range hood's operating status. The first detection component detects the stove temperature when the range hood is in standby mode, controlling whether to switch the range hood to on mode; the second detection component detects the stove temperature when the range hood is on, controlling whether to switch the range hood to standby mode without affecting the fume extraction effect. A radar component detects the presence of people nearby, controlling the range hood's status and issuing alarms based on the detected stove temperature to prevent accidents caused by user forgetfulness, thus protecting user safety. Combined with ambient temperature detection, it intelligently controls the cooling equipment's operation, freeing up the user's hands and providing a technologically convenient and comfortable kitchen experience, improving the user's quality of life.

[0116] Figure 4This is a flowchart of another control method for a range hood provided by an embodiment of the present invention. The present invention refines the above embodiment. For step S120, which controls whether the range hood switches from standby mode to on mode and whether to issue an alarm based on the first temperature of the stove and the situation of people near the range hood, it can be refined into the following steps:

[0117] When the cooktop is in the first temperature range, the range hood is kept in standby mode.

[0118] When the first temperature of the stove is in the second temperature range and there are people near the range hood, control the range hood to switch from standby mode to on mode;

[0119] The temperature values ​​in the first temperature range are lower than those in the second temperature range.

[0120] Furthermore, the second temperature range includes a first temperature sub-range and a second temperature sub-range, wherein the temperature value in the first temperature sub-range is lower than the temperature value in the second temperature sub-range.

[0121] The above step S120, which controls whether the range hood switches from standby mode to on mode and whether an alarm is triggered based on the first temperature of the stove and the number of people near the range hood, also includes:

[0122] When the first temperature of the stove is in the first temperature sub-range and there is no one near the range hood, control the range hood to keep it in standby mode;

[0123] An alarm will be triggered when the first temperature of the stove is in the second temperature sub-range and no one is near the range hood.

[0124] Furthermore, the second detection component 30 includes a first infrared temperature sensor and a second infrared temperature sensor, and the stove 200 includes a first burner 201 and a second burner 202; the first infrared temperature sensor faces the first burner 201, and the second infrared temperature sensor faces the second burner 202; the second temperature includes the first burner temperature and the second burner temperature.

[0125] The above steps, when the appliance is powered on, involving the detection of the second temperature of the stove using the second detection component, can be broken down into the following steps:

[0126] When the machine is powered on, the temperature of the first burner head is detected by the first infrared temperature sensor, and the temperature of the second burner head 202 is detected by the second infrared temperature sensor.

[0127] The above step S140, which controls the operating level of the range hood and whether the range hood switches from the on state to the standby state based on the second temperature of the stove, can be further broken down into the following steps:

[0128] Based on the highest temperature between the first and second burner heads, control the operating level of the range hood and whether the range hood switches from the on state to the standby state.

[0129] For details not covered in this embodiment, please refer to the previous embodiment.

[0130] refer to Figures 1-2 and Figure 4 The control method for a range hood provided in this embodiment of the invention includes the following specific steps:

[0131] S210. In standby mode, the first temperature of the stove is detected by the first detection component, and the situation of people near the range hood is detected by the radar component.

[0132] S221. When the first temperature of the stove is in the first temperature range, control the range hood to remain in standby mode.

[0133] Among them, the first temperature range t1 is the range of values ​​of the first temperature T1 of the cooktop 200 that the range hood can maintain in standby mode.

[0134] Specifically, if the first temperature T1 of the stove detected by the first detection component 20 is within the first temperature range t1, it proves that the stove 200 is not in working condition and no oil fumes are generated, so the range hood can continue to remain in standby mode.

[0135] S222. When the first temperature of the stove is in the second temperature range and there are people near the range hood, control the range hood to switch from standby mode to on mode.

[0136] Among them, the temperature value in the first temperature range t1 is less than the temperature value in the second temperature range t2. The second temperature range t2 is the range of values ​​of the first temperature T1 of the stove 200 that needs to be switched from standby to on state when the range hood is in standby state.

[0137] Specifically, if the first temperature T1 of the stove detected by the first detection component 20 is in the second temperature range t2, and the temperature has increased, it proves that the stove 200 is in working condition, producing oil fumes, and if someone is detected nearby, then the range hood will switch to the on state.

[0138] For example, the first temperature range t1 can be a left-open range, and the second temperature range t2 can be a right-open range. The right endpoint value of the first temperature range t1 is the same as the left endpoint value of the second temperature range t2, which is essentially a threshold. The threshold can be set according to the experiment. For example, the threshold can be 50℃, that is, t1 is (0℃, 50℃) and t2 is [50℃, +∞). When the measured first temperature T1 is within the first temperature range t1, the range hood remains in standby mode; when the measured first temperature T1 is within the second temperature range t2, the range hood switches to the on mode.

[0139] S223. When the first temperature of the stove is in the first temperature sub-range and there is no one near the range hood, control the range hood to remain in standby mode.

[0140] The second temperature interval t2 includes the first temperature sub-interval t. 21 The first temperature sub-interval t 21 This refers to the temperature range reached by the cooktop when the range hood is in standby mode and the user is cooking and producing relatively little smoke.

[0141] Specifically, when the range hood is in standby mode, the first temperature T1 of the cooktop 200 is within the first temperature sub-range t. 21 When the system detects that no one is nearby, the range hood remains in standby mode.

[0142] S224. When the first temperature of the stove is in the second temperature sub-range and there is no one near the range hood, an alarm will be triggered.

[0143] The second temperature interval t2 includes the second temperature sub-interval t 22 The second temperature sub-interval t 22 This refers to the temperature range reached by the cooktop when the range hood is in standby mode and the user is cooking and producing a large amount of oil fumes.

[0144] Specifically, when the range hood is in standby mode, the first temperature T1 of the cooktop 200 is within the second temperature sub-range t. 22 When the system detects that no one is nearby, it will issue an alarm.

[0145] For example, the first temperature sub-interval t 21 The right endpoint value and the second temperature sub-interval t 22 The left endpoint values ​​are the same, which is essentially a threshold. The threshold can be set according to the experiment. For example, the threshold can be 200℃, that is, the first temperature sub-interval t. 21 The first temperature is [50℃, 200℃), and the second temperature sub-interval is [200℃, +∞). When the measured first temperature T1 is within the first temperature sub-interval t... 21When no one is nearby, the range hood remains in standby mode; when the measured first temperature T1 is within the second temperature sub-range t 22 At that time, and if no one is nearby, an alarm will be triggered.

[0146] S230. When the machine is powered on, the temperature of the first burner head of the first burner head is detected by the first infrared temperature sensor, and the temperature of the second burner head of the second burner head 202 is detected by the second infrared temperature sensor; the radar component is used to detect the situation of people near the range hood, and the first detection component is used to detect the ambient temperature of the range hood.

[0147] Specifically, the second detection component 30 includes a first infrared temperature sensor (not shown in the figure) and a second infrared temperature sensor (not shown in the figure), and the stove 200 includes a first burner 201 and a second burner 202; the first infrared temperature sensor faces the first burner 201, and the second infrared temperature sensor faces the second burner 202; the second temperature T2 includes the first burner temperature T 21 Second furnace head temperature T 22 That is, the temperature of the first furnace head 201 detected by the first infrared temperature sensor of the second detection component 30 is T. 21 The second infrared temperature sensor of the second detection component 30 detects the second furnace head temperature of the second furnace head 202 as T. 22 The first detection component 20 detects the ambient temperature T of the range hood.

[0148] S240. Based on the highest temperature between the first burner temperature and the second burner temperature, control the operating level of the range hood and whether the range hood switches from the on state to the standby state.

[0149] For example, when the threshold for the range hood's on / off state and standby state is set to 50°C, the detected temperature T of the first burner head... 21 The temperature is 30℃, while the temperature of the second furnace head is T. 22 The temperature is 60℃, and the highest temperature at this point is the second furnace head temperature T. 22 If the detected temperature of the first burner head T is higher than the threshold, the range hood will remain on. 21 The temperature is 40℃, while the temperature of the second furnace head is T. 22 The temperature is 30℃, and the highest temperature at this point is the temperature T of the first furnace head. 21 If the value is below the threshold, the range hood will switch from being on to being in standby mode.

[0150] S250: Control the working status of the cooling equipment according to the number of people near the range hood and the ambient temperature.

[0151] The control method for a range hood provided in this embodiment of the invention includes: in a standby state, detecting a first temperature of the cooktop using a first detection component and detecting the presence of people near the range hood using a radar component; when the first temperature of the cooktop is within a first temperature range, controlling the range hood to remain in standby mode; when the first temperature of the cooktop is within a second temperature range and there are people near the range hood, controlling the range hood to switch from standby mode to on mode; when the first temperature of the cooktop is within a first temperature sub-range and there are no people near the range hood, controlling the range hood to remain in standby mode; when the first temperature of the cooktop is within a second temperature sub-range and there are no people near the range hood, issuing an alarm notification; and in the on mode... The system utilizes a first infrared temperature sensor to detect the temperature of the first burner head and a second infrared temperature sensor to detect the temperature of the second burner head. It also uses a radar component to detect the presence of people near the range hood and a first detection component to detect the ambient temperature of the range hood. Based on the higher of the first and second burner head temperatures, it controls the operating level of the range hood and whether to switch it from on to standby mode. When the ambient temperature of the range hood is in the fifth temperature range, it maintains the range hood in standby mode. When the ambient temperature of the range hood is in the sixth temperature range, it controls the operation of the cooling equipment in real time based on the presence of people near the range hood. This method improves the conditions for a range hood to switch from standby to on, enabling it to intelligently detect when the user is cooking and automatically turn on to filter fumes, thus enhancing user satisfaction. It also improves the conditions for switching from on to standby by separately monitoring the temperature of each burner on the stove, improving detection accuracy. This allows the range hood to detect when the user has finished cooking and intelligently switch to standby mode, eliminating the need for the user to turn it off manually. It ensures that all remaining fumes are filtered before switching back to standby, preventing users from forgetting to turn it off, protecting user health, saving electricity, and improving user experience. Furthermore, the method adds the ability to detect nearby people, improving the range hood's operating status, and provides alarm prompts for dangerous situations, increasing kitchen safety.

[0152] Furthermore, the temperature range includes a third temperature range and a fourth temperature range, where the temperature value in the third temperature range is lower than the temperature value in the fourth temperature range.

[0153] The above step S240, which controls the operating level of the range hood and whether the range hood switches from the on state to the standby state based on the higher temperature between the first burner temperature and the second burner temperature, can be further broken down into the following steps:

[0154] S241. When both the first burner temperature and the second burner temperature are in the third temperature range, control the range hood to switch from the on state to the standby state.

[0155] Among them, the third temperature range t3 is the first burner temperature T that the range hood needs to switch to standby mode when it is turned on. 21 Second furnace head temperature T 22 The range of values ​​for .

[0156] Specifically, if the first infrared temperature sensor detects the temperature T of the first furnace head... 21 It is in the third temperature range t3, and the second infrared temperature sensor detects the second furnace head temperature T. 22 If the temperature is also within the third temperature range t3, it proves that the stove 200 is not in working condition and no oil fumes are produced, so the range hood switches to standby mode.

[0157] For example, the third temperature range t3 is set to (0, 45°C), and the first infrared temperature sensor detects the temperature T of the first furnace head. 21 The second infrared temperature sensor detects the temperature T of the second furnace head at 35℃. 22 The temperature is 40℃, which is within the third temperature range t3, indicating that the user is not cooking and the fumes have been completely filtered. Therefore, the range hood is switched from the on state to the standby state.

[0158] S242. When the temperature of the first burner head and / or the temperature of the second burner head reach the fourth temperature range, control the working level of the range hood according to the temperature of the first burner head and / or the temperature of the second burner head that have reached the fourth temperature range.

[0159] Among them, the temperature value in the third temperature range t3 is lower than the temperature value in the fourth temperature range t4. The fourth temperature range t4 is the pre-set first burner temperature T that the range hood maintains when it is turned on. 21 Second furnace head temperature T 22 The range of values ​​for is important to note. It can be either one temperature is within this range and the other is below it, or both are within this range.

[0160] Specifically, if the temperature of the first furnace head is T 21 Second furnace head temperature T 22 If at least one temperature reaches the fourth temperature range t4, it proves that the stove 200 is in working condition and produces oil fumes. The range hood is controlled to operate in different states according to the temperature.

[0161] For example, the fourth temperature range t4 is set to [45℃, +∞), and the first infrared temperature sensor detects the temperature T of the first furnace head. 21The second infrared temperature sensor detects the temperature T of the second furnace head at 35℃. 22 If the temperature is 50℃, indicating that there is a fourth temperature range t4, it means that the user is cooking. Therefore, the range hood will remain on and the amount of oil fumes will be determined based on the highest temperature. The corresponding range hood working level will then be selected to completely filter the oil fumes.

[0162] The control method provided by this invention can divide the measured temperature range of the first burner and the second burner when the range hood is turned on, and specify the state of the range hood for different situations, which is more in line with the actual situation and improves the user's quality of life.

[0163] Optionally, the first temperature range and the third temperature range are the same, and the second temperature range and the fourth temperature range are the same.

[0164] For example, the first temperature range t1 and the third temperature range t3 are the same, which is (0, 50℃), and the second temperature range t2 and the fourth temperature range t4 are the same, which is [50℃, +∞). That is, the switching temperature threshold for the standby state and the on state of the range hood is the same.

[0165] Furthermore, regarding the above step S242, when the temperature of the first burner and / or the temperature of the second burner reach the fourth temperature range, controlling the operating level of the range hood based on the temperature of the first burner and / or the temperature of the second burner reaching the fourth temperature range can be refined into the following steps:

[0166] When the temperature of the first burner head and / or the temperature of the second burner head reach the fourth temperature range, the range hood is controlled to operate at the range hood speed corresponding to the temperature sub-range where the temperature of the first burner head and / or the temperature of the second burner head that reaches the fourth temperature range is located.

[0167] Among them, the temperature sub-interval is a further division of the fourth temperature interval t4 to classify the range of the first burner temperature and the second burner temperature, determine the amount of oil fumes generated during the user's cooking process, and then determine the range hood setting.

[0168] Figure 5 This is a flowchart of another control method for a range hood provided by an embodiment of the present invention. The embodiments of the present invention further refine the above embodiments. The range hood has three speed settings: a first speed setting, a second speed setting, and a third speed setting. The operating power of the first speed setting, the second speed setting, and the third speed setting increases sequentially.

[0169] The fourth temperature range includes the third temperature sub-range, the fourth temperature sub-range, and the fifth temperature sub-range; the temperature values ​​of the third temperature sub-range, the fourth temperature sub-range, and the fifth temperature sub-range increase sequentially.

[0170] Based on the temperature sub-range where the first burner temperature and / or the second burner temperature fall within the fourth temperature range, the above steps control the range hood to operate at the corresponding range hood setting for that temperature sub-range. Specifically, this can be broken down as follows:

[0171] When the temperature of the first burner head and / or the temperature of the second burner head reach the third temperature sub-range, control the range hood to operate at the first setting;

[0172] When the temperature of the first burner head and / or the temperature of the second burner head reach the fourth temperature sub-range, control the range hood to operate at the second setting;

[0173] When the temperature of the first burner head and / or the temperature of the second burner head reach the fifth temperature sub-range, control the range hood to operate at the third setting.

[0174] For details not covered in this embodiment, please refer to the previous embodiment.

[0175] refer to Figures 1-2 and Figure 5 The control method for a range hood provided in this embodiment of the invention includes the following specific steps:

[0176] S310. In standby mode, the first detection component detects the first temperature of the stove, and the radar component detects the presence of people near the range hood.

[0177] S321. When the first temperature of the stove is in the first temperature range, control the range hood to remain in standby mode.

[0178] S322. When the first temperature of the stove is in the second temperature range and there are people near the range hood, control the range hood to switch from standby mode to on mode.

[0179] S323. When the first temperature of the stove is in the first temperature sub-range and there is no one near the range hood, control the range hood to remain in standby mode.

[0180] S324. When the first temperature of the stove is in the second temperature sub-range and there is no one near the range hood, an alarm will be triggered.

[0181] S330: When the machine is powered on, the first infrared temperature sensor is used to detect the temperature of the first burner head, and the second infrared temperature sensor is used to detect the temperature of the second burner head; the radar component is used to detect the presence of people near the range hood, and the first detection component is used to detect the ambient temperature of the range hood.

[0182] S341. When both the first burner temperature and the second burner temperature are in the third temperature range, control the range hood to switch from the on state to the standby state.

[0183] S342. When the temperature of the first burner head and / or the temperature of the second burner head reach the third temperature sub-range, control the range hood to operate at the first setting.

[0184] Among them, the third temperature sub-interval t 43 This refers to the temperature range reached by the first burner and / or the second burner when the range hood produces relatively little smoke during operation. The first setting corresponds to the operating setting of the range hood when producing less smoke under different cooking conditions.

[0185] Specifically, when the temperature T of the first furnace head is detected... 21 Second furnace head temperature T 22 In the middle, at least one temperature reaches the third temperature sub-interval t 43 At that time, control the range hood to run at the first speed setting.

[0186] For example, the range hood can be set to three operating levels: low, high, and high-power, with the operating power increasing sequentially. The first level corresponds to the low level, and the third temperature sub-range t is set accordingly. 43 It is [50℃, 100℃), at which point the temperature T of the first furnace head was measured. 21 The temperature is 30℃, while the temperature of the second furnace head is T. 22 The temperature is 60℃, and the highest temperature at this point is the second furnace head temperature T. 22 And reach the third temperature sub-interval t 43 If so, the range hood will be controlled to operate at the lowest setting, i.e., the first setting.

[0187] S343. When the temperature of the first burner head and / or the temperature of the second burner head reach the fourth temperature sub-range, control the range hood to operate at the second setting.

[0188] Among them, the fourth temperature sub-interval t 44 The first setting refers to the temperature range reached by the first burner and / or the second burner when the range hood produces a moderate amount of cooking fumes. The second setting refers to the operating setting of the range hood when producing a moderate amount of cooking fumes under different cooking conditions.

[0189] Specifically, when the temperature T of the first furnace head is detected... 21 Second furnace head temperature T 22 In the middle, at least one temperature reaches the fourth temperature sub-interval t 44 At that time, control the range hood to run at the second speed.

[0190] For example, the range hood can be set to a low, high, and high-power setting, with the operating power increasing sequentially. The second setting corresponds to the high setting, and the fourth temperature sub-range t is set accordingly. 44 It is [100℃, 200℃), at which point the temperature T of the first furnace head was measured. 21 The temperature is 60℃, while the temperature of the second furnace head is T.22 The temperature is 110℃, and the highest temperature at this point is the second furnace head temperature T. 22 And reaches the fourth temperature sub-interval t 44 If so, the range hood will be controlled to operate at the highest setting, i.e., the second setting.

[0191] S344. When the temperature of the first burner head and / or the temperature of the second burner head reach the fifth temperature sub-range, control the range hood to operate at the third gear.

[0192] Among them, the fifth temperature sub-interval t 45 The first setting refers to the temperature range reached by the first burner and / or the second burner when the range hood produces a large amount of cooking fumes. The third setting corresponds to the operating level of the range hood when producing a large amount of cooking fumes under different cooking conditions.

[0193] Specifically, when the temperature T of the first furnace head is detected... 21 Second furnace head temperature T 22 In the middle, at least one temperature reaches the fifth temperature sub-interval t. 45 At that time, control the range hood to run at the third speed setting.

[0194] For example, the range hood can be set to a low, high, and high-power setting, with the operating power increasing sequentially. The third setting corresponds to the high-power setting, and the fifth temperature sub-range t is set accordingly. 45 It is [200℃, +∞), at which point the temperature T of the first furnace head was measured. 21 The temperature is 60℃, while the temperature of the second furnace head is T. 22 The temperature is 210℃, and the highest temperature at this point is the second furnace head temperature T. 22 And reach the fifth temperature sub-interval t 45 If you select the desired setting, the range hood will be set to the stir-fry setting, which is the third setting.

[0195] The control method provided in this embodiment of the invention, when the range hood is turned on, refines the range hood's power settings into a first power setting, a second power setting, and a third power setting, with the operating power of the first, second, and third power settings increasing sequentially; it also refines the fourth temperature range into a third temperature sub-range, a fourth temperature sub-range, and a fifth temperature sub-range, with the temperature values ​​of the third, fourth, and fifth temperature sub-ranges increasing sequentially. The method also addresses the measurement of the first burner temperature T. 21 and / or the second furnace head temperature T 22 The system determines the temperature range reached and then controls the range hood to operate at the corresponding setting. This control method assesses the amount of oil fumes generated based on different burner temperatures and then intelligently controls the range hood to operate at the corresponding setting. This ensures that the appropriate range hood setting is selected for the cooking situation, which not only filters the oil fumes completely but also saves electricity and improves the practicality of the range hood.

[0196] Figure 6 This is a flowchart of another control method for a range hood provided by an embodiment of the present invention. The present invention further refines the above embodiment. For step S150, which controls the working state of the cooling device based on the situation of people near the range hood and the ambient temperature, it can be refined into the following steps:

[0197] When the ambient temperature of the range hood is in the fifth temperature range, control the range hood to keep it in standby mode;

[0198] When the ambient temperature of the range hood is in the sixth temperature range, the working status of the cooling equipment is controlled in real time according to the situation of people near the range hood.

[0199] The temperature values ​​in the fifth temperature range are lower than those in the sixth temperature range.

[0200] For details not covered in this embodiment, please refer to the previous embodiment.

[0201] refer to Figures 1-2 and Figure 6 The control method for this range hood includes the following steps:

[0202] S410. In standby mode, the first detection component detects the first temperature of the stove, and the radar component detects the presence of people near the range hood.

[0203] S421. When the first temperature of the stove is in the first temperature range, control the range hood to remain in standby mode.

[0204] S422. When the first temperature of the stove is in the second temperature range and there are people near the range hood, control the range hood to switch from standby mode to on mode.

[0205] S430. When the appliance is powered on, the second detection component is used to detect the second temperature of the stove.

[0206] S440: Based on the second temperature of the stove, control the working level of the range hood and whether the range hood switches from the on state to the standby state.

[0207] S451. When the ambient temperature of the range hood is in the fifth temperature range, control the range hood to remain in standby mode.

[0208] Among them, the fifth temperature range t5 is the range of ambient temperature T that the range hood needs to maintain in standby mode.

[0209] Specifically, when the range hood is in standby mode, the first detection component 20 detects that the ambient temperature T is in the fifth temperature range t5, and controls the range hood to remain in standby mode.

[0210] S452. When the ambient temperature of the range hood is in the sixth temperature range, the working status of the cooling equipment shall be controlled in real time according to the situation of people near the range hood.

[0211] Among them, the temperature value in the fifth temperature range t5 is lower than the temperature value in the sixth temperature range t6. The sixth temperature range t6 is the range of ambient temperature T that needs to be reached when the range hood is in standby mode and the cooling equipment needs to be operated depending on whether there are people nearby.

[0212] Specifically, when the range hood is in standby mode, if the first detection component 20 detects that the ambient temperature T is in the sixth temperature range t6 and detects that someone is nearby, it will control the cooling device to start cooling. If no one is detected nearby, it can start cooling or not cool and trigger an alarm.

[0213] For example, the fifth temperature range t5 can be a left-open range, and the sixth temperature range t6 can be a right-open range. The right endpoint value of the fifth temperature range t5 and the left endpoint value of the sixth temperature range t6 are the same, which is essentially a threshold. The threshold can be set according to the experiment. For example, the threshold can be 40℃, that is, t5 is (0℃, 40℃) and t6 is [40℃, +∞). When the ambient temperature T measured by the first detection component 20 is in the fifth temperature range t5, the range hood maintains a standby state; when the measured ambient temperature T is in the sixth temperature range t6, if someone is detected nearby, the cooling device is controlled to start cooling; if no one is detected nearby, the cooling can start, or the cooling can be stopped and an alarm or other actions can be performed.

[0214] This invention provides a control method for a range hood. By dividing the detected ambient temperature into a fifth temperature range and a sixth temperature range, the method improves the control of the range hood and cooling equipment based on the specific range of the detected ambient temperature. Furthermore, it intelligently controls the working status of the cooling equipment based on whether anyone is nearby, preventing the kitchen temperature from becoming too high, improving user comfort, and saving electricity.

[0215] Optionally, step S252 above can be further refined by controlling the working status of the cooling equipment in real time based on the number of people near the range hood.

[0216] S4521. When there are people near the range hood, control the cooling equipment to turn on.

[0217] Specifically, when the range hood is in standby mode, if the first detection component 20 detects that the ambient temperature T is in the sixth temperature range t6 and detects that someone is nearby, it will control the cooling device to start cooling.

[0218] S4522. When no one is near the range hood for a preset time, control the cooling equipment to turn off.

[0219] The preset time is the duration during which the range hood is in standby mode, the ambient temperature is in the sixth temperature range, and no one is present.

[0220] Specifically, when the range hood is in standby mode, if the first detection component 20 detects that the ambient temperature T is in the sixth temperature range t6 and the duration of the detection that no one is nearby exceeds a preset time, then the cooling device will be turned off.

[0221] For example, if the preset time is set to 2 minutes, when the range hood is in standby mode, if the first detection component 20 detects that the ambient temperature T is in the sixth temperature range t6 and detects that someone is nearby, then the cooling device will start cooling. If no one is detected near the range hood and the duration exceeds 2 minutes, then the cooling device will stop running; or if the first detection component 20 detects that the ambient temperature T is in the sixth temperature range t6 and detects that no one is nearby, then the cooling device will remain off.

[0222] The range hood control method provided in this embodiment improves upon the ambient temperature detection results in the above embodiments. When someone is present, the cooling device is activated; otherwise, it is deactivated. This method improves detection accuracy, enabling the system to detect whether the user has finished cooking and control the cooling device's operation accordingly. This eliminates the need for the user to manually turn off the cooling device, ensuring that the kitchen temperature is lowered after cooking, providing a comfortable cooking space. Furthermore, the intelligent deactivation of the cooling device prevents the user from forgetting to turn it off, thus providing a comfortable space, saving electricity, and enhancing the user experience.

[0223] Optionally, both the first temperature range and the fifth temperature range are left infinite ranges, with the right endpoint of the first temperature range being a1 and the right endpoint of the fifth temperature range being a2.

[0224] Both the second and sixth temperature ranges are right infinity ranges. The left endpoint of the second temperature range is a1, and the left endpoint of the sixth temperature range is a2.

[0225] Where a1 > a2.

[0226] Specifically, the first temperature range is (0, a1), the fifth temperature range is (0, a2), the second temperature range is (a1, +∞), and the sixth temperature range is (a2, +∞).

[0227] It is understandable that a1 and a2 are the thresholds for state switching.

[0265] The range hood control method provided in this embodiment of the invention controls the range hood's operating level, alarm status, and the working status of various cooling devices by detecting the stove temperature and whether anyone is nearby, in order to meet the user's different needs in various situations.

[0266] Figure 8 This is a schematic diagram of the structure of a control device for a range hood provided in an embodiment of the present invention. (Refer to...) Figures 1-2 and Figure 8 The range hood is used in conjunction with cooling equipment;

[0267] The range hood includes an air guide plate 12, a first detection component 20, a second detection component 30, and a radar component; the first detection component 20 and the second detection component 30 are respectively located in the spaces on opposite sides of the air guide plate 12.

[0268] When the air guide plate 12 is in the closed state, it blocks the space between the second detection component 30 and the cooktop 200; when the air guide plate 12 is in the open state, it blocks the space between the first detection component 20 and the cooktop 200. The specific structure of the range hood and the installation positions of the first detection component 20 and the second detection component 30 can be found in the above embodiment, and will not be repeated here.

[0269] The control device includes:

[0270] The first detection module 101 is used to detect the first temperature of the stove 200 using the first detection component 20 and to detect the presence of people near the range hood using the radar component in standby mode.

[0271] Specifically, in standby mode, when the air guide plate 12 is closed, the air guide plate 12 blocks the space between the second detection component 30 and the stove 200. At this time, the first detection module 101 uses the first detection component 20 to detect the first temperature T1 of the stove 200, and the first detection module 101 uses the radar component to detect the situation of people near the range hood.

[0272] The control module 102 is used to control whether the range hood switches from standby mode to on mode and whether to issue an alarm prompt based on the first temperature of the stove 200 and the number of people near the range hood; wherein, in standby mode, the air guide plate 12 is closed; in on mode, the air guide plate 12 is open.

[0273] Specifically, if the first temperature T1 of the cooktop 200 is equal to or higher than the preset temperature, and there are people nearby, the control module 102 controls the range hood to switch from standby mode to on mode; if there are no people nearby, an alarm is triggered; if the first temperature T1 of the cooktop 200 is lower than the preset temperature, the range hood is kept in standby mode.

[0274] When powered on, the second detection module 103 uses the second detection component 30 to detect the second temperature of the stove 200, uses the radar component to detect the presence of people near the range hood, and uses the first detection component 20 to detect the ambient temperature of the range hood.

[0275] Specifically, when the first temperature detected by the first detection component 20 is higher than the set temperature, and there are people nearby, and the range hood is turned on, the air guide plate 12 is in the open state, and the air guide plate 12 blocks the first temperature measuring component 20 and the stove 200. At this time, the second detection module 103 uses the second detection component 30 to start detecting the second temperature T2 of the stove 200, and the second temperature measuring module 103 uses the radar component to detect the situation of people near the range hood, and at the same time uses the first detection component 20 to detect the ambient temperature of the range hood.

[0276] The control module 102 is also used to control the working level of the range hood and whether the range hood switches from the on state to the standby state based on the second temperature of the cooktop 200.

[0277] Specifically, when the second temperature T2 of the cooktop 200 is compared with the preset temperature, if the second temperature T2 is lower than the preset temperature, the state control module 102 controls the range hood to switch from the on state to the standby state; if the second temperature T2 is equal to or higher than the preset temperature, the range hood is kept on.

[0278] The control module 102 is also used to control the working status of the cooling equipment based on the number of people near the range hood and the ambient temperature.

[0279] Specifically, the control module 102 compares the measured ambient temperature T with the preset ambient temperature. If the ambient temperature T is equal to or higher than the preset ambient temperature and someone is detected nearby, the control module 102 controls the cooling device to start cooling. If no one is detected nearby, the cooling device can start cooling or not cool and will start an alarm. If the ambient temperature T is lower than the preset ambient temperature, the control module 102 controls the cooling device to stop working.

[0280] The control device for a range hood provided in this embodiment of the invention uses a first detection module to detect the first temperature of the stove using a first detection component and a radar component to detect the presence of people near the range hood when the range hood is in standby mode. Then, a control module controls whether the range hood switches from standby mode to on mode and whether to issue an alarm based on the first temperature of the stove and the presence of people near the range hood. Next, a second detection module, when the range hood is on, uses a second detection component to detect the second temperature of the stove, a radar component to detect the presence of people near the range hood, and a first detection component to detect the ambient temperature of the range hood. Based on the second temperature of the stove, the control module controls the operating level of the range hood and whether it switches from on mode to standby mode. The control module also controls the operating status of the cooling equipment based on the presence of people near the range hood and the ambient temperature. The above technical solution utilizes the first and second detection modules to detect the stove temperature to determine whether cooking is taking place. It also detects whether there are people nearby and the ambient temperature. Subsequently, the control module intelligently controls the switching of the range hood's working state, as well as the working state of the alarm and cooling devices. This allows the range hood, alarm devices, and cooling devices to respond intelligently to different states, making it more convenient for users, protecting their health, and improving their quality of life.
