[0002] As living standards improve, residents are paying more and more attention to the air quality in their kitchens. The fumes produced by Chinese cooking have always been a problem for users. Some manufacturers are developing ventilation equipment such as range hoods that can automatically adjust their speed to remove these fumes. These devices typically use infrared dust sensors to detect dust particles in the ventilation channels, thereby determining the amount of fumes and automatically adjusting the speed accordingly.

[0003] However, by the time the dust sensor detects dust particles, the kitchen space is already filled with some cooking fumes, which affects the fume extraction effect of the kitchen appliances. Furthermore, the dust sensor has difficulty distinguishing between water vapor and cooking fumes. Summary of the Invention

These embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0047] In the description of the embodiments of the present invention, it should be noted that the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to detachable connections or integral connections; they can refer to mechanical connections, electrical connections, or connections that allow for mutual communication; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0048] Please see Figure 1 This invention provides a control method for a kitchen appliance 100. The control method includes the following steps:

[0049] Step S10: Obtain the temperature information and gas composition information of the kitchen;

[0050] Step S20: Based on the temperature information and gas composition information, determine whether to turn on the fan assembly 60 of the kitchen appliance 100;

[0051] Step S30: Obtain humidity information and dust information of the kitchen;

[0052] Step S40: Based on the humidity and dust information, determine whether to adjust the operating parameters of the fan assembly 60.

[0053] The control method of the kitchen appliance 100 according to the present invention first determines whether the user has started cooking based on temperature information and gas composition information, thereby controlling the operation of the fan assembly 60 in a timely manner to avoid turning on the fan assembly 60 only after the oil fumes have already dissipated in the kitchen. Then, by acquiring the humidity information and dust information of the kitchen, the operating parameters of the fan assembly 60 are adjusted or kept unchanged, so that the air volume of the fan assembly 60 matches the content of oil fumes and water vapor in the kitchen.

[0054] Specifically, the temperature information is used to represent the temperature of the kitchen. This temperature information can represent the temperature of the cooking appliance because the temperature of the environment around the cooking appliance will also increase during the cooking process. Therefore, this temperature information can also represent the temperature of the environment around the cooking appliance, such as the temperature of a certain place inside the kitchen appliance 100.

[0055] Gas composition information is used to indicate the gas composition in the kitchen. This gas composition information is related to the fumes produced during cooking. During the cooking process, specific gases, such as polycyclic aromatic hydrocarbons, are produced. Therefore, based on the gas composition information, it can be determined whether the user has started cooking.

[0056] Based on temperature information indicating a rise in the current kitchen temperature and gas composition information indicating the presence of cooking gases in the kitchen, the system can assume that the user is cooking and promptly activate the fan assembly 60. Compared to existing kitchen appliances that rely solely on dust information to determine whether to activate the fan assembly, this invention enables faster activation of the fan assembly 60, effectively preventing situations where cooking fumes have already dissipated in the kitchen before the fan assembly 60 has even started to turn on.

[0057] It is worth noting that after the fan assembly 60 is turned on, its initial operating parameters can be adjusted based on actual use, simulation results, etc. In some embodiments, since the amount of oil fumes is usually small at the beginning of cooking, the initial operating parameters of the fan assembly 60 can be set relatively low. As cooking progresses and the amount of oil fumes gradually increases, humidity and dust information are also collected, so the operating parameters can be increased based on the humidity and dust information.

[0058] Humidity information is used to indicate the humidity in the kitchen. During cooking, water vapor is generated, which increases the humidity. The fan assembly 60 can also be used to draw in and discharge water vapor to prevent the kitchen from becoming too humid. Therefore, the operating parameters of the fan assembly 60 can be adjusted according to the humidity information so that the fan assembly 60 can discharge water vapor from the kitchen in a timely manner.

[0059] Dust information is used to represent particles in the kitchen, which can include oil fume particles, water vapor, etc. The greater the amount of dust represented by the dust information, the greater the required operating parameters of the fan assembly 60, thus adjusting the operating parameters of the fan assembly 60 according to the dust information. It is worth noting that, under the same dust information, if there is more water vapor and fewer oil fume particles, the operating parameters of the fan assembly 60 can be smaller, while if there is less water vapor and more oil fume particles, the operating parameters of the fan assembly 60 can be larger.

[0060] It should be noted that the operating parameters of the fan assembly 60 can be adjusted based solely on humidity or dust information. For example, if the humidity information indicates that the kitchen environment has reached a certain level of humidity, then it can be determined that the operating parameters of the fan assembly 60 should be adjusted and the airflow of the fan assembly 60 should be increased. Similarly, if the dust information indicates that the kitchen environment has a certain dust content, then it can be determined that the operating parameters of the fan assembly 60 should be adjusted and the airflow of the fan assembly 60 should be increased. Because this invention determines whether to turn on the fan assembly 60 based on temperature and gas composition information, and adjusts the operating parameters based on humidity and dust information, it can effectively avoid the situation of accidentally turning on the fan assembly 60. For example, during the rainy season when the kitchen humidity is very high, the fan assembly 60 will not be turned on incorrectly due to humidity information; similarly, when the user is using flour in the kitchen, the fan assembly 60 will not be turned on incorrectly due to dust information.

[0061] It's worth noting that, after determining whether to turn on the fan assembly 60 based on temperature and gas composition information, the operating parameters of the fan assembly 60 can be adjusted based on humidity and dust information. This is because, typically, if the kitchen temperature doesn't rise and no gases produced along with cooking fumes are detected, it can be inferred that the user is not cooking, thus eliminating the need to adjust the fan assembly 60's operating parameters. However, if the temperature and gas composition information indicate that the user is not cooking, but the humidity or dust information exceeds a threshold, an alert can be issued to the user, allowing them to adjust the thresholds or perform sensor maintenance.

[0062] The operating parameters of the fan assembly 60 may include data such as air volume, voltage, and current, without specific limitations.

[0063] It is worth adding that the kitchen appliance 100 can also be equipped with components such as lights and air conditioners. It can determine to turn on the lights at the same time as the fan assembly 60 based on temperature and gas composition information; it can also determine to turn on the air conditioner based on temperature information, and adjust the operating parameters of the air conditioner based on temperature information.

[0064] In some implementations, please refer to Figure 2 Step S20 includes:

[0065] Step S21: If the temperature information is greater than the first temperature threshold and the gas composition information is greater than the first composition threshold, determine to turn on the fan assembly 60.

[0066] Step S23: If the temperature information is less than the first temperature threshold and / or the gas composition information is less than the first composition threshold, determine that the fan assembly 60 will not be turned on.

[0067] This configuration avoids the situation where the fan assembly 60 is turned on incorrectly due to errors in temperature or gas composition measurements. The temperature and gas composition information corroborate each other, ensuring that the fan assembly 60 is turned on when the user starts cooking.

[0068] Specifically, the speed of acquiring temperature and gas composition information is faster than the speed of acquiring humidity and dust information. Therefore, determining whether to turn on the fan component 60 based on the temperature and gas composition information can quickly respond to the cooking fumes.

[0069] There are many possible values ​​for the first temperature threshold, which can be set according to actual usage requirements, simulation results, etc., and no specific restrictions are imposed here.

[0070] There are many possible values ​​for the first component threshold, which can be set according to actual usage requirements, simulation results, etc., and no specific restrictions are imposed here.

[0071] In some implementations, please refer to Figure 3 The operating parameters of the fan assembly 60 include air volume. Step S40 includes:

[0072] Step S41: If the humidity information is greater than the first humidity threshold, increase the air volume of the fan assembly 60.

[0073] Step S42: When the humidity information is less than the first humidity threshold and greater than the second humidity threshold, keep the air volume of the fan assembly 60 unchanged, and the second humidity threshold is less than the first humidity threshold.

[0074] Step S43: If the humidity information is less than the second humidity threshold, reduce the air volume of the fan assembly 60.

[0075] This setting allows the airflow of the fan assembly 60 to be adjusted according to humidity information, so that the airflow of the fan assembly 60 matches the humidity environment of the kitchen.

[0076] Specifically, there are many possible values ​​for the first and second humidity thresholds, which can be set according to actual usage requirements, simulation results, etc., and no specific restrictions are imposed here. The value of the increase or decrease in air volume by the fan component 60 can be set by the manufacturer during production or by the user according to usage needs, and no specific restrictions are imposed here.

[0077] In some implementations, please refer to Figure 4 The operating parameters of the fan assembly 60 include air volume. Step S40 includes:

[0078] Step S45: If the dust information is greater than the first dust threshold, increase the air volume of the fan assembly 60;

[0079] Step S46: When the dust information is less than the first dust threshold and greater than the second dust threshold, keep the air volume of the fan assembly 60 unchanged, and the second dust threshold is less than the first dust threshold.

[0080] Step S47: If the dust information is less than the second dust threshold, reduce the air volume of the fan assembly 60.

[0081] This configuration allows the airflow of the fan assembly 60 to be adjusted based on dust information, ensuring that the airflow of the fan assembly 60 matches the dust environment of the kitchen.

[0082] Specifically, there are many possible values ​​for the first and second dust thresholds, which can be set according to actual usage requirements, simulation results, etc., and no specific restrictions are imposed here. The value of the increased or decreased airflow of the fan component 60 can be set by the manufacturer during production or by the user according to usage needs, and no specific restrictions are imposed here.

[0083] It is worth noting that the operating parameters of the fan assembly 60 can be adjusted based on both humidity and dust information.

[0084] For example, if the humidity information is greater than a first humidity threshold and the dust information is greater than a first dust threshold, the air volume of the fan assembly 60 is increased; if the humidity information is greater than a first humidity threshold and the dust information is less than a second dust threshold, the air volume of the fan assembly 60 is kept constant; if the humidity information is less than a second humidity threshold and the dust information is less than a second dust threshold, the air volume of the fan assembly 60 is decreased.

[0085] At this point, the specific reduction or increase in air volume can be calculated by adding or subtracting the air volume value obtained from humidity information and the air volume value obtained from dust information, and no specific restrictions are imposed here.

[0086] The operating parameters of the fan assembly 60 can also be adjusted based on humidity and dust information.

[0087] For example, if humidity information is obtained first, then step S41, step S42 or step S43 is performed based on the humidity information. If dust information is obtained, then step S45, step S46 or step S47 is performed based on the dust information.

[0088] Specifically, in one embodiment, if the humidity information is greater than a first humidity threshold, the air volume of the fan assembly 60 is increased according to the humidity information. If the dust information is less than a second dust threshold, the air volume of the fan assembly 60 is decreased according to the dust information.

[0089] It is worth noting that the increase or decrease in airflow based on humidity information can be the same as or different from the increase or decrease in airflow based on dust information. In one embodiment, if the increase in airflow based on dust information is greater than the increase in airflow based on humidity information, then when the dust information is greater than a first dust threshold and the humidity information is less than a second humidity threshold, the airflow of the fan assembly 60 is increased, and the increase in airflow of the fan assembly 60 is the difference between the increase in airflow based on dust information and the increase in airflow based on humidity information.

[0090] In some embodiments, the control method for the kitchen appliance 100 further includes:

[0091] If the temperature information is less than the second temperature threshold, the gas composition information is less than the second composition threshold, the humidity information is less than the third humidity threshold, and the dust information is less than the third dust threshold, then the fan assembly 60 of the kitchen appliance 100 is turned off.

[0092] This setup allows the fan component 60 to be turned off when the user stops cooking, saving energy.

[0093] Specifically, the second temperature threshold is lower than the first temperature threshold, the second component threshold is lower than the second component threshold, the third humidity threshold is lower than the second humidity threshold, and the third dust threshold is lower than the second dust threshold.

[0094] In some embodiments, the control method for the kitchen appliance 100 further includes:

[0095] Based on temperature, gas composition, humidity, and dust information, determine cooking habits.

[0096] In this way, based on established cooking habits, the kitchen appliance system can promptly remind users of information, providing them with a good experience. In addition, it can also provide health reminders and recipe recommendations based on cooking habits.

[0097] Please see Figure 5 and Figure 6 This invention provides a kitchen appliance 100, including a temperature sensor 10, a gas composition sensor 20, a humidity sensor 30, a dust sensor 40, a controller 50, and a fan assembly 60. The temperature sensor 10 acquires temperature information of the kitchen. The gas composition sensor 20 acquires gas composition information of the kitchen. The humidity sensor 30 acquires humidity information of the kitchen. The dust sensor 40 acquires dust information of the kitchen. The controller 50 is connected to the temperature sensor 10, gas composition sensor 20, humidity sensor 30, and dust sensor 40 respectively, and is used to determine whether to turn on the fan assembly 60 of the kitchen appliance 100 based on the temperature information and the gas composition information, and to determine whether to adjust the operating parameters of the fan assembly 60 based on the humidity information and the dust information. The fan assembly 60 operates according to the operating parameters.

[0098] The kitchen appliance 100 of this invention first determines whether the user has started cooking based on temperature and gas composition information, thereby controlling the operation of the fan assembly 60 in a timely manner to avoid turning on the fan assembly 60 only after the oil fumes have already dissipated in the kitchen. Then, by acquiring the humidity and dust information of the kitchen, the operating parameters of the fan assembly 60 are adjusted or kept unchanged, so that the air volume of the fan assembly 60 matches the content of oil fumes and water vapor in the kitchen.

[0099] Specifically, kitchen appliance 100 is a top-draft kitchen appliance 100. It is understood that in other embodiments, kitchen appliance 100 can be a bottom-draft kitchen appliance 100 or a side-draft kitchen appliance 100, etc., and is not specifically limited here. The following description uses the example of a top-draft kitchen appliance 100 for detailed explanation. Specifically, kitchen appliance 100 includes, but is not limited to, range hoods, integrated cooktops, and other appliances with fume extraction functions. The following explanation uses a range hood as an example. The range hood can be a variable frequency range hood.

[0100] The kitchen appliance 100 of this application includes, but is not limited to, a detection device 70, a housing, a baffle assembly, and a check valve. A temperature sensor 10, a gas composition sensor 20, a humidity sensor 30, and a dust sensor 40 are installed inside the detection device 70. The housing is mounted on the baffle assembly. The baffle assembly has a smoke collection chamber and multiple function buttons. The smoke collection chamber has an oil filter and a top plate. The multiple function buttons allow users to input operating commands. A fan assembly 60 is installed inside the housing. The fan assembly 60 includes a volute, a fan, an air inlet, and an air outlet. The fan is located inside the volute, and a volute duct is formed inside the volute. The air inlet allows oil fumes to enter the fan assembly 60, and the air outlet connects to the volute duct to exhaust the oil fumes from the fan assembly 60. A check valve is connected to the top of the housing, and a check valve duct is formed inside the check valve. It is understood that a check valve is a valve whose opening and closing element is a circular valve disc that relies on its own weight and the pressure of the medium to prevent backflow of the medium. The check valve can be a lift check valve or a swing check valve. The detection device 70 should be installed at a location in the kitchen appliance 100 where the oily gas will pass through, such as the center of the deflector plate or the air inlet of the fan assembly 60, so that the oily gas can enter the detection device 70 for detection.

[0101] Temperature sensor 10 can be a resistance temperature detector (RTD) sensor, thermocouple sensor, etc., without specific limitations. Gas composition sensor 20 can be an integrated TVOC (Volatile Organic Compounds) sensor, infrared gas sensor, etc., without specific limitations. Humidity sensor 30 can be a resistive sensor, capacitive sensor, etc., without specific limitations. It is worth noting that humidity sensor 30 and temperature sensor 10 can be the same sensor, that is, this sensor is an integrated temperature and humidity sensor 30. Dust sensor 40 can be an infrared detection sensor or laser detection sensor, etc., without specific limitations. The following embodiment uses dust sensor 40 as an infrared detection sensor for detailed explanation.

[0102] The dust sensor 40 may include a light emitting component and a light receiving component. The light emitting component emits light, and the light receiving component receives the light emitted by the light emitting component. The light receiving component can also output an electrical signal based on the received light, so that the controller 50 can obtain dust information. In one embodiment, when dust particles pass through the optical path of the infrared light emitted by the light emitting component, they can block, scatter, and diffract the infrared light. That is, dust particles can affect the intensity of the light emitted by the light emitting component received by the light receiving component, causing a change in the light received by the light receiving component, and the concentration of dust particles can be determined based on this change.

[0103] In some implementations, the controller 50 may be equipped with a communication module that can connect to mobile terminals such as mobile phones, tablets, and computers, allowing users to control other components of the kitchen appliance 100 through the controller 50. In addition, the controller 50 can also upload humidity information, gas composition information, temperature information, dust information, etc. to the mobile terminal, enabling the mobile terminal to determine the user's eating habits based on various information, and thus provide services such as cleaning reminders and recipe recommendations based on the user's eating habits.

[0104] In some implementations, please refer to Figure 7 The detection device 70 also includes a housing 71, which includes an upper housing 71a and a lower housing 71b. The upper housing 71a and the lower housing 71b surround and form a receiving cavity 75. The housing 71 also includes an air inlet (not marked) and an air outlet 76, which are respectively connected to the receiving cavity 75. The humidity sensor 30, the gas composition sensor 20, the dust sensor 40, and the controller 50 are all installed in the receiving cavity 75.

[0105] With this configuration, the housing 71 can protect the humidity sensor 30, gas composition sensor 20, dust sensor 40, and controller 50, and facilitate their installation.

[0106] Specifically, after the user starts cooking, the airflow moves under the action of the fan assembly 60 and enters the receiving cavity 75 through the air inlet. The humidity sensor 30, gas composition sensor 20, and dust sensor 40 detect the gas in the receiving cavity 75. The detected gas is discharged from the detection device 70 through the air outlet 76.

[0107] The shell 71 can have many shapes, such as cuboid, sphere, cone, etc., and no specific limitation is made here. In one embodiment, the shell 71 is spindle-shaped, that is, the outer diameter of the shell 71 gradually increases from top to bottom and then gradually decreases from top to bottom. In this way, the oil droplets condensed on the outer wall of the shell 71 can drip off naturally under the action of gravity, reducing the speed at which the outer wall of the shell 71 is contaminated by oil.

[0108] The shape of the receiving cavity 75 can be various, such as cuboid, sphere, or cone. The shape of the receiving cavity 75 can be adapted to the shape of the shell 71, and no specific limitation is made here.

[0109] The air inlet is used for airflow to enter the receiving cavity 75. The air outlet 76 is used for airflow to exit the receiving cavity 75. There are many possible relative positions of the air inlet and the air outlet 76. For example, the air inlet and the air outlet 76 can be located at the left and right ends of the receiving cavity 75, with the air inlet and the air outlet 76 positioned at the same height; or the air inlet and the air outlet 76 can be located at one end of the receiving cavity 75, with the air inlet positioned lower than the air outlet 76. These are just a few examples.

[0110] In some embodiments, the air inlet and air outlet 76 can be located at opposite ends of the receiving cavity 75. The gas discharged into the receiving cavity 75 through the air inlet moves away from the air inlet, thereby allowing the gas to move away from the air inlet while simultaneously approaching the air outlet 76. This increases the probability that the oil fume particles entering the receiving cavity 75 through the air inlet can be discharged through the air outlet 76 more quickly, reducing the probability that the oil fume particles will escape from the receiving cavity 75 and pollute the receiving cavity 75.

[0111] Furthermore, the air inlet and outlet 76 can be located at the upper and lower ends of the receiving cavity 75, with the air inlet located directly below the outlet 76. Since gas usually moves upward, the gas entering the receiving cavity 75 from the air inlet can naturally move to the outlet 76 for discharge, further reducing the probability of oil fume particles escaping within the receiving cavity 75. In addition, this arrangement makes the movement of gas relatively concentrated, which is more conducive to gas detection.

[0112] In some implementations, please refer to Figure 7 The housing 71 includes multiple fins 73, each fin 73 is provided with a vent 74, the multiple fins 73 are spaced apart, and a space is formed between adjacent fins 73 for mounting the humidity sensor 30 and / or the gas composition sensor 20 and / or the humidity sensor 30 and / or the dust sensor 40.

[0113] With this configuration, multiple fins 73 can limit the humidity sensor 30 and / or gas composition sensor 20 and / or humidity sensor 30 and / or dust sensor 40, thereby enabling the installation of the humidity sensor 30 and / or gas composition sensor 20 and / or humidity sensor 30 and / or dust sensor 40.

[0114] Specifically, the detection device 70 may include a mounting section, which, together with the housing 71, forms a receiving cavity. Multiple fins 73 are respectively mounted within the receiving cavity. A humidity sensor 30 and / or a gas composition sensor 20 and / or a dust sensor 40 detect the gas within the receiving cavity 75 through a vent 74. Thus, the multiple fins 73 cause the inner diameter of the receiving cavity to continuously change, ensuring that oil fume particles entering the receiving cavity are adsorbed onto the multiple fins 73, reducing the probability of oil fume particles contacting the humidity sensor 30 and / or the gas composition sensor 20 and / or the dust sensor 40.

[0115] The vent 74 of the fin 73 can be circular, which can shape the light when the dust sensor 40 is an infrared detection sensor. All fins 73 can be connected to the mounting part, all fins 73 can be connected to the upper shell 71a, all fins 73 can be connected to the lower shell 71b, or some fins 73 can be connected to the upper shell 71a and some to the lower shell 71b. In this way, the multiple fins 73 can cooperate with each other as the upper shell 71a and the lower shell 71b are assembled.

[0116] For further details, please refer to Figure 7 The fin 73 includes an upper fin 731 and a lower fin 732. One end of the upper fin 731 is connected to the upper shell 71a, and the other end of the upper fin 731 is recessed with a first ventilation groove 7311. One end of the lower fin 732 is connected to the lower shell 71b, and the other end of the lower fin 732 is recessed with a second ventilation groove 7321. The first ventilation groove 7311 and the second ventilation groove 7321 are combined to form a ventilation hole 74.

[0117] With this configuration, the upper piece 731 and the lower piece 732 are joined together to form a ventilation hole. During production, the upper piece 731 with the first ventilation groove 7311 and the lower piece 732 with the second ventilation groove 7321 are produced separately to facilitate demolding.
