Description

Technical Field

[0001] This application relates to the field of range hood technology, and more specifically, to a range hood and a heating control method. Background Technology

[0002] Currently, when an induction cooktop is used below a range hood for cooking, condensation forms on the surface of the air intake grille or air deflector. As the condensation accumulates, it drips onto the cooking utensils below. Related technologies incorporate deflectors to divert the condensation, but some dripping still occurs onto the cooktop. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0004] In view of the above, an embodiment of the first aspect of this application provides a range hood.

[0005] An embodiment of the second aspect of this application provides a heating control method.

[0006] To achieve the above objectives, an embodiment of the first aspect of this application provides a range hood, comprising: a housing with an air duct inside; a condenser plate disposed on the air inlet side of the air duct; a heating device disposed on the condenser plate, wherein the heating device and the condenser plate conduct heat; a sensor for detecting sensing parameters of water mist on the condenser plate; and a controller electrically connected to the sensor and the heating device, wherein the controller is used to control the opening and closing of the heating device according to the sensing parameters of the sensor.

[0007] The range hood provided according to the embodiments of this application includes a housing and a condenser plate, a heating device, and a sensor located within the housing. The housing primarily provides protection for the internal structure. An air duct is installed within the housing to facilitate the exhaust of cooking fumes from the air inlet. Furthermore, a condenser plate is installed on the air inlet side of the air duct. During cooking, water vapor rises to the air inlet and condenses on the condenser plate when it comes into contact with the range hood's air guide plate or filter, as the water vapor still has a certain temperature. It is important to emphasize that by installing a heating device on the condenser plate, the heating device can be controlled to operate when condensation is present on the condenser plate. Through heat conduction with the condenser plate, the temperature of the condenser plate is increased, thereby reducing the formation of condensation and decreasing the possibility of dripping into the cooking pot below the range hood, thus improving the user experience.

[0008] In the present application, the heating device is turned on and off during the cooking process based on the sensing parameters determined by the sensor, and is not turned on throughout the entire cooking process. This reduces the requirements for energy consumption and the heat resistance of the fixed heating device, and is more energy-efficient while solving the problem of condensation.

[0009] It is understood that this application mainly utilizes the combined function of sensors and controllers. The sensor only needs to be located inside the housing to detect the sensing parameters of water mist on the condenser plate. It can be directly installed on the condenser plate, or on the heating device, or on any structure inside the housing.

[0010] The air duct is equipped with a fan that drives air to flow from the air inlet to the air outlet. A guide plate or filter is installed at the air inlet.

[0011] In the above technical solution, the heating device specifically includes: a heating plate that is attached to the condensing plate, and a sensor located on the side of the heating plate facing the condensing plate.

[0012] In this technical solution, the heating device mainly includes a heating plate that is attached to the condenser plate, thereby enabling heat conduction between the heating device and the condenser plate. That is, the heat generated by the heating device will be transferred to the condenser plate, thereby reducing the possibility of condensation on the condenser plate.

[0013] The sensor is located on the side of the heating plate facing the condenser plate, which improves the accuracy of obtaining the sensing parameters of water mist on the condenser plate.

[0014] In the above technical solution, there are multiple sensors, which are arranged in a matrix array on the heating plate.

[0015] In this technical solution, multiple sensors are arranged in a matrix array on the heating plate. Each sensor can acquire sensing parameters at its corresponding location. By comprehensively judging multiple sensing parameters, the accuracy of determining whether condensation exists on the condenser plate can be improved. Furthermore, because of the matrix array of multiple sensors, when condensation occurs at a certain local location on the condenser plate, at least one sensor in the heating plate array will detect it. Therefore, it can also determine the location of condensation and further control the heating plate to heat that area.

[0016] In the above technical solution, the heating plate is located on the side of the condenser plate facing the air duct, and the sensor is located between the condenser plate and the heating device.

[0017] In this technical solution, the heating plate is placed on the side of the condenser plate facing the air duct, and the sensor is located between the condenser plate and the heating device so that the sensor can properly detect the water mist level on the condenser plate.

[0018] In the above technical solution, the sensor specifically includes at least one water mist sensor, and the controller is used to control the heating device to turn on when the sensing parameters of the water mist sensor are within the defogging range, and otherwise control the heating device to turn off.

[0019] In this technical solution, a water mist sensor can be selected. The water mist sensor can acquire sensing parameters and send them to the controller. The controller can determine the presence of water mist on the condenser plate based on the specific sensing parameters, and a defogging range is preset. When the sensing parameters are within the defogging range, it is assumed that water mist exists on the condenser plate and defogging is required. At this time, the heating device is turned on to defog the surface of the condenser plate. After the water mist is removed, defogging is considered unnecessary when the sensing parameters exceed the defogging range, and the heating device can be turned off. This allows the heating device to be turned on only when defogging is needed, saving energy while still achieving the desired defogging effect.

[0020] In the above technical solution, the sensor specifically includes at least one temperature sensor, and the controller is used to control the heating device to turn on when the temperature parameter of the temperature sensor is not greater than a first temperature threshold, and to control the heating device to turn off when the temperature parameter is not less than a second temperature threshold.

[0021] In this technical solution, a temperature sensor can be used as the sensor. The temperature sensor can acquire temperature parameters and send them to the controller. The controller can make judgments based on the specific temperature parameters, and a first temperature threshold and a second temperature threshold are preset. When the temperature parameter is not greater than the first temperature threshold, it is considered that water vapor exists on the condenser plate and a defogging operation is required. At this time, the heating device is turned on to defog the surface of the condenser plate. After the water vapor is removed, the temperature rises to a level not lower than the second temperature threshold, at which point it is considered that defogging is no longer necessary, and the heating device can be turned off. Thus, the heating device is only turned on when defogging is needed, which saves energy while achieving the defogging effect.

[0022] In the above technical solution, the condenser plate is made of glass, and the sensing parameters include temperature, humidity, dryness, and reflectivity.

[0023] In this technical solution, by limiting the material of the condenser plate to glass, the sensor can accurately determine whether there is water mist on the glass surface by acquiring temperature, humidity, dryness, and reflectivity.

[0024] An embodiment of the second aspect of this application provides a heating control method, including determining sensing parameters through a sensor; determining whether water mist has formed on the condenser plate of the range hood based on the sensing parameters, and generating a judgment result; when the judgment result is yes, controlling the heating device to turn on and heat the condenser plate, until the judgment result is no, controlling the heating device to turn off.

[0025] According to the heating control method provided in this application, the sensing parameters are first determined by the sensor, and the formation of water mist on the condenser plate is judged by the sensing parameters. When there is condensation on the condenser plate, the heating device can be controlled to operate. Under the action of heat conduction with the condenser plate, the temperature of the condenser plate is increased, thereby reducing the generation of condensation on the condenser plate and reducing the possibility of dripping into the cooking pot below the range hood, thus improving the user experience.

[0026] In the present application, the heating device is turned on and off during the cooking process based on the sensing parameters determined by the sensor, and is not turned on throughout the entire cooking process. This reduces the requirements for energy consumption and the heat resistance of the fixed heating device, and is more energy-efficient while solving the problem of condensation.

[0027] In the above technical solution, the sensor is a water mist sensor; the determination of whether water mist has formed on the condenser plate of the range hood is based on the sensing parameters, and the generation of the determination result, specifically includes: determining the sensing parameters of the water mist sensor, and if the sensing parameters are within the demisting range, the determination result is yes, otherwise the determination result is no.

[0028] In this technical solution, a water mist sensor can be selected. The water mist sensor can acquire sensing parameters and send them to the controller. The controller can determine the presence of water mist on the condenser plate based on the specific sensing parameters, and a defogging range is preset. When the sensing parameters are within the defogging range, it is assumed that water mist exists on the condenser plate and defogging is required. At this time, the heating device is turned on to defog the surface of the condenser plate. After the water mist is removed, defogging is considered unnecessary when the sensing parameters exceed the defogging range, and the heating device can be turned off. This allows the heating device to be turned on only when defogging is needed, saving energy while still achieving the desired defogging effect.

[0029] In the above technical solution, the sensor is a temperature sensor; the determination of whether water mist is formed on the condenser plate of the range hood based on the sensing parameters and the generation of the determination result specifically includes: determining the temperature parameters of the temperature sensor; when the temperature parameters are not greater than a first temperature threshold, the determination result is yes; when the temperature parameters are not less than a second temperature threshold, the determination result is no; wherein, the first temperature threshold is less than the second temperature threshold.

[0030] In this technical solution, a temperature sensor can be used as the sensor. The temperature sensor can acquire temperature parameters and send them to the controller. The controller can make judgments based on the specific temperature parameters, and a first temperature threshold and a second temperature threshold are preset. When the temperature parameter is not greater than the first temperature threshold, it is considered that water vapor exists on the condenser plate and a defogging operation is required. At this time, the heating device is turned on to defog the surface of the condenser plate. After the water vapor is removed, the temperature rises to a level not lower than the second temperature threshold, at which point it is considered that defogging is no longer necessary, and the heating device can be turned off. Thus, the heating device is only turned on when defogging is needed, which saves energy while achieving the defogging effect.

[0039] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this application, the embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific implementation methods. It should be noted that, unless otherwise specified, the embodiments of this application and the features within them can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0041] The following reference Figures 1 to 5 Some embodiments according to this application are described.

[0042] Example 1

[0043] like Figure 1 and Figure 3 As shown, the range hood 100 proposed in this embodiment includes a housing 102 and a condenser plate 104, a heating device 106, and a sensor 108 located within the housing 102. The housing 102 mainly provides protection for the internal structure. By setting an air duct 1022 inside the housing 102, the cooking fumes at the air inlet are discharged to the outside. In addition, a condenser plate 104 is provided on the air inlet side of the air duct 1022 so that when the water vapor generated during cooking rises to the air inlet and comes into contact with the air guide plate or filter of the range hood, the water vapor will condense on the condenser plate 104 because it still has a certain temperature. It should be emphasized that by setting a heating device 106 on the condenser plate 104, the heating device 106 can be controlled to operate when there is condensation on the condenser plate 104. Under the effect of heat conduction with the condenser plate 104, the temperature of the condenser plate 104 is increased, thereby reducing the generation of condensation on the condenser plate 104 and reducing the possibility of dripping into the cooking pot below the range hood 100, thus improving the user experience.

[0044] In the present application, the heating device 106 is turned on and off during the cooking process based on the sensing parameters determined by the sensor 108, and is not turned on throughout the entire cooking process. This reduces the requirements for energy consumption and the heat resistance of the fixed heating device 106, and is more energy-efficient while solving the problem of condensation.

[0045] It is understood that this application mainly utilizes the combined function of sensor 108 and controller 110. The sensor 108 only needs to be located inside the housing 102 to detect the sensing parameters of water mist on the condenser plate 104. It can be directly set on the condenser plate 104, or it can be set on the heating device 106, or it can be set on any structure inside the housing 102.

[0046] The air duct 1022 is equipped with a fan that can drive air from the air inlet to the air outlet. A guide plate or filter will be installed at the air inlet.

[0047] Furthermore, the heating device 106 mainly includes a heating plate 1062 that is attached to the condenser plate 104, thereby enabling heat conduction between the heating device 106 and the condenser plate 104. That is, the heat generated by the heating device 106 will be transferred to the condenser plate 104, thereby reducing the possibility of condensation on the condenser plate 104.

[0048] The sensor 108 is located on the side of the heating plate 1062 facing the condenser plate 104, thereby improving the accuracy of obtaining the sensing parameters of water mist on the condenser plate 104.

[0049] Furthermore, multiple sensors 108 are arranged in a matrix array on the heating plate 1062. Each sensor 108 can acquire sensing parameters at its corresponding location. By comprehensively judging multiple sensing parameters, the accuracy of determining whether condensation exists on the condenser plate 104 can be improved. Simultaneously, because the multiple sensors 108 are arranged in a matrix array, when condensation occurs at a certain local location on the condenser plate 104, at least one sensor 108 in the array on the heating plate 1062 will be able to detect it. Therefore, it can also determine the location of condensation, and further control the heating plate 1062 to heat the area at that location.

[0050] Example 2

[0051] like Figure 1 As shown, the range hood 100 proposed in this embodiment includes a housing 102 and a condenser plate 104, a heating device 106, and a sensor 108 located within the housing 102. The housing 102 mainly provides protection for the internal structure. By setting an air duct 1022 inside the housing 102, the cooking fumes at the air inlet are discharged to the outside. In addition, a condenser plate 104 is provided on the air inlet side of the air duct 1022 so that when the water vapor generated during cooking rises to the air inlet and comes into contact with the air guide plate or filter of the range hood, the water vapor will condense on the condenser plate 104 because it still has a certain temperature. It should be emphasized that by setting a heating device 106 on the condenser plate 104, the heating device 106 can be controlled to operate when there is condensation on the condenser plate 104. Under the effect of heat conduction with the condenser plate 104, the temperature of the condenser plate 104 is increased, thereby reducing the generation of condensation on the condenser plate 104 and reducing the possibility of dripping into the cooking pot below the range hood 100, thus improving the user experience.

[0052] In the present application, the heating device 106 is turned on and off during the cooking process based on the sensing parameters determined by the sensor 108, and is not turned on throughout the entire cooking process. This reduces the requirements for energy consumption and the heat resistance of the fixed heating device 106, and is more energy-efficient while solving the problem of condensation.

[0053] The sensor 108 can be a water mist sensor 1082. The water mist sensor 1082 can acquire sensing parameters and send them to the controller 110. The controller 110 can determine the defogging range based on the specific sensing parameters. When the sensing parameters are within the defogging range, it is considered that there is water mist on the condenser plate 104 and a defogging operation is required. At this time, the heating device 106 is turned on to defog the surface of the condenser plate 104. After the water mist is removed, the heating device 106 is turned off when the sensing parameters exceed the defogging range. This allows the heating device 106 to be turned on only when defogging is needed, saving energy while still achieving the defogging effect.

[0054] It is understood that this application mainly utilizes the combined function of sensor 108 and controller 110. The sensor 108 only needs to be located inside the housing 102 to detect the sensing parameters of water mist on the condenser plate 104. It can be directly set on the condenser plate 104, or it can be set on the heating device 106, or it can be set on any structure inside the housing 102.

[0055] The air duct 1022 is equipped with a fan that can drive air from the air inlet to the air outlet. A guide plate or filter will be installed at the air inlet.

[0056] Example 3

[0057] like Figure 2 As shown, the range hood 100 proposed in this embodiment includes a housing 102 and a condenser plate 104, a heating device 106, and a sensor 108 located within the housing 102. The housing 102 mainly provides protection for the internal structure. By setting an air duct 1022 inside the housing 102, the cooking fumes at the air inlet are discharged to the outside. In addition, a condenser plate 104 is provided on the air inlet side of the air duct 1022 so that when the water vapor generated during cooking rises to the air inlet and comes into contact with the air guide plate or filter of the range hood, the water vapor will condense on the condenser plate 104 because it still has a certain temperature. It should be emphasized that by setting a heating device 106 on the condenser plate 104, the heating device 106 can be controlled to operate when there is condensation on the condenser plate 104. Under the effect of heat conduction with the condenser plate 104, the temperature of the condenser plate 104 is increased, thereby reducing the generation of condensation on the condenser plate 104 and reducing the possibility of dripping into the cooking pot below the range hood 100, thus improving the user experience.

[0058] In the present application, the heating device 106 is turned on and off during the cooking process based on the sensing parameters determined by the sensor 108, and is not turned on throughout the entire cooking process. This reduces the requirements for energy consumption and the heat resistance of the fixed heating device 106, and is more energy-efficient while solving the problem of condensation.

[0059] The sensor 108 can be a temperature sensor 1084. The temperature sensor 1084 can acquire temperature parameters and send them to the controller 110. The controller 110 can make judgments based on the specific temperature parameters, and has a first temperature threshold and a second temperature threshold set in advance. When the temperature parameter is not greater than the first temperature threshold, it is considered that there is water mist on the condenser plate 104, and a defogging operation is required. At this time, the heating device 106 is turned on to perform a defogging effect on the surface of the condenser plate 104. After the water mist is removed, until the temperature rises to not less than the second temperature threshold, it is considered that defogging is not required, and the heating device 106 can be turned off. Thus, the heating device 106 is only turned on when defogging is needed, which saves energy while achieving the defogging effect.

[0060] It is understood that this application mainly utilizes the combined function of sensor 108 and controller 110. The sensor 108 only needs to be located inside the housing 102 to detect the sensing parameters of water mist on the condenser plate 104. It can be directly set on the condenser plate 104, or it can be set on the heating device 106, or it can be set on any structure inside the housing 102.

[0061] The air duct 1022 is equipped with a fan that can drive air from the air inlet to the air outlet. A guide plate or filter will be installed at the air inlet.

[0062] Based on any of the above embodiments, the condenser plate 104 is made of glass, and the sensor 108 can accurately determine whether there is water mist on the glass surface by acquiring temperature, humidity, dryness and reflectivity.

[0063] Example 4

[0064] like Figure 4 As shown, the heating control method proposed in this embodiment includes step S102: determining sensing parameters through a sensor; step S104: determining whether water mist is formed on the condenser plate of the range hood 100 according to the sensing parameters, and generating a judgment result; step S106: when the judgment result is yes, controlling the heating device 106 to turn on and heat the condenser plate until the judgment result is no, controlling the heating device to turn off.

[0065] First, the sensor determines the sensing parameters. The sensor determines whether water mist is formed on the condenser plate. When there is condensation on the condenser plate, the heating device can be controlled to operate. Through heat conduction with the condenser plate, the temperature of the condenser plate is increased, thereby reducing the generation of condensation on the condenser plate and reducing the possibility of dripping into the cooking pots below the range hood, thus improving the user experience.

[0066] In the present application, the heating device is turned on and off during the cooking process based on the sensing parameters determined by the sensor, and is not turned on throughout the entire cooking process. This reduces the requirements for energy consumption and the heat resistance of the fixed heating device, and is more energy-efficient while solving the problem of condensation.

[0067] Furthermore, sensor 108 can be a water mist sensor 1082. The water mist sensor 1082 can acquire sensing parameters and send them to controller 110. Controller 110 can determine the defogging range in advance based on the specific sensing parameters. When the sensing parameters are within the defogging range, it is considered that there is water mist on the condenser plate 104 and defogging is required. At this time, the heating device 106 is turned on to defog the surface of the condenser plate 104. After the water mist is removed, defogging is considered unnecessary when the sensing parameters exceed the defogging range. At this time, the heating device 106 can be turned off, so that the heating device 106 is only turned on when defogging is needed, thus saving energy while achieving the defogging effect.

[0068] Example 4

[0069] like Figure 5 As shown, the heating control method proposed in this embodiment includes step S202: determining sensing parameters through a sensor; step S204: determining the temperature parameters of the temperature sensor, and determining the result as yes when the temperature parameters are not greater than a first temperature threshold, and determining the result as no when the temperature parameters are not less than a second temperature threshold; step S206: controlling the heating device to turn on when the determination result is yes, heating the condenser plate until the determination result is no, and controlling the heating device to turn off.

[0070] A temperature sensor can be used to acquire temperature parameters and send them to the controller. The controller can then make judgments based on the specific temperature parameters, with a first temperature threshold and a second temperature threshold pre-set. When the temperature parameter is not greater than the first temperature threshold, it is considered that water vapor exists on the condenser plate and a defogging operation is required. At this time, the heating device is turned on to defog the surface of the condenser plate. After the water vapor is removed, the temperature rises to a level not lower than the second temperature threshold, at which point defogging is considered unnecessary, and the heating device can be turned off. This allows the heating device to be turned on only when defogging is needed, saving energy while still achieving the desired defogging effect.

[0071] This application provides a specific embodiment of a range hood, including: an air inlet, a guide plate, a filter, a smoke collection hood, a fan system, a smoke exhaust outlet, a condenser plate assembly, and a heating module. The fan system includes a volute and an impeller. The heating module is mounted above and attached to the condenser plate assembly. A check valve is also provided, connecting the air outlet of the fan system to the air inlet of the check valve, with the air outlet of the check valve serving as the smoke exhaust outlet of the entire range hood.

[0072] The heating module includes heating material (i.e., heating plate 1062), water mist sensor, and temperature sensor.

[0073] In one specific embodiment, a water mist sensor is integrated into the heating module. When the range hood is started, high-temperature water vapor liquefies on the room-temperature condenser glass, forming small water droplets. During the range hood's operation, the fan carries away some of the water vapor, but not all of it, leaving most of the vapor liquefied on the condenser glass surface, forming small water droplets. This application uses the water mist sensor to detect the presence of water mist (but not water droplets) on the condenser glass surface, then powers on the heating unit to defog the surface. When the sensor detects no water mist, the defogging process stops. After cooking, the power is turned off, ending the entire process. By controlling the time difference between powering on and off, energy savings are achieved, reducing user costs and increasing user satisfaction.

[0074] In another specific embodiment, a temperature sensor is placed within the heating module. When the range hood is started, high-temperature water vapor liquefies on the room-temperature condenser glass, forming small water droplets. During the range hood's operation, the fan carries away some of the water vapor, but not all of it, leaving most of the vapor liquefied on the condenser glass surface, forming small water droplets. When the water mist sensor detects water mist on the condenser glass surface (without forming water droplets), the temperature detected by the temperature sensor is set as the initial temperature T0. When the temperature detected by the temperature sensor reaches the initial temperature T0, the heating unit on the glass surface is energized to defog the condenser glass surface. After the water mist sensor determines that there is no water mist on the condenser glass surface, the temperature detected by the temperature sensor is set as the final temperature T1. When the temperature reaches the final temperature T1, the dehumidification process on the condenser glass surface is stopped. This prevents damage to electronic components due to excessively high temperatures, improving safety. By controlling the time difference between on and off, energy savings are achieved, reducing user operating costs and increasing user satisfaction.

[0075] According to the range hood and heating control method provided in this application, by setting up a heating device and a sensor, the start-up and shutdown of the heating device during the cooking process are determined by the sensing parameters determined by the sensor, and it is not turned on throughout the entire cooking process. This reduces the requirements for energy consumption and the heat resistance of the fixed heating device, and is more energy-efficient while solving the problem of condensation.
