Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a range hood and stove. Background Technology

[0002] Range hoods are responsible for quickly removing waste from stove combustion and harmful fumes produced during cooking, expelling them outdoors. Since the amount of fumes varies constantly during cooking, and different cooking methods produce different amounts of fumes, users need to manually adjust the range hood's power according to the amount of fumes produced.

[0003] In response, some range hood systems use image acquisition to determine the working status of the cooktop. Specifically, infrared and color cameras are respectively set on the side of the range hood. The infrared and color cameras work together to identify the working status of the cooktop and control the start or stop of the fan drive motor accordingly, as well as adjust the speed of the fan, to achieve the effect of automatically adjusting the power of the range hood.

[0004] However, in practice, it has been found that the installation distance and angle between the infrared camera and the color camera can affect the accuracy of the image acquisition. Installing the infrared camera and the color camera separately can lead to inconvenience in the production and installation of the whole machine, difficulty in adjusting the consistency of product performance, and thus directly affect the analysis results.

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown 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 this utility model, and should not be construed as limiting this utility model.

[0035] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] In the description of this utility model, "multiple" means two or more, and "greater than," "less than," "exceeding," etc., are understood to exclude the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] The following is for reference. Figure 1 and Figure 3 This invention describes a range hood according to an embodiment of the present invention.

[0039] like Figure 1 and Figure 3 As shown, the range hood according to an embodiment of the present utility model includes a housing 110 and a camera module 130.

[0040] The housing 110 has a built-in motor 200 that can drive the range hood 210 to rotate. A control panel 120 is provided at the bottom of the front side wall of the housing 110. The camera module 130 is located on the control panel 120 and is located at the center of the front side wall of the housing 110. The camera module 130 includes a module body 131, and a number of infrared cameras 132 and image cameras 133 are fixedly connected to the module body 131. The infrared cameras 132 are distributed on the left and right sides of the image cameras 133.

[0041] For example, taking the intelligent range hood of this utility model as an example, such as Figure 1 and Figure 3 As shown, the housing 110 houses a motor and a control module. A control panel 120 is located at the bottom of the front sidewall of the housing 110. A camera module 130 is mounted on the control panel 120, positioned at the center of the front sidewall of the housing 110. This allows the camera module 130 to acquire image information from at least two stove burners within the detection range using only one camera module structure. The control module is electrically connected to the camera module 130, the control panel 120, and the motor. (Refer to...) Figure 2 The camera module 130 includes a main body 131, on which several infrared cameras 132 and image cameras 133 are fixedly connected. The infrared cameras 132 are distributed on the left and right sides of the image cameras 133. That is, the camera module 130 integrates infrared cameras 132 and image cameras 133. The infrared cameras 132, distributed on both sides, ensure accurate acquisition of infrared radiation within the detection range and output infrared thermal images to the control module. The image cameras 133 are used to acquire smoke within the detection range and output images to the control module.

[0042] The control module uses a camera module 130 to collect real-time images of the stove area and related image data such as infrared thermal imaging. It identifies the gradient distribution of smoke concentration and dynamically adjusts the power of the motor 200 based on the smoke diffusion pattern, thereby adjusting the speed of the range hood driven by the motor 200. This enables the range hood to achieve intelligent automatic control functions, with stronger airflow for heavy smoke and weaker airflow for light smoke.

[0043] Since the camera module 130 integrates an infrared camera 132 and an image camera 133, installing the camera module 130 is sufficient to install the infrared camera 132 and the image camera 133. Furthermore, the infrared camera 132 and the image camera 133 are fixed to the module body 131, ensuring that the distance and angle between them remain precise and constant. This eliminates the need for additional camera debugging steps and guarantees the detection accuracy of the infrared camera 132 and the image camera 133, ensuring the stability of the entire range hood in judging the stove's working status and correspondingly controlling the operation of the range hood fan 210. In other words, it ensures that the range hood fan 210 can perform consistent operations under specific working conditions.

[0044] In some embodiments of this utility model, the motor is a three-phase brushless DC motor.

[0045] In some embodiments of this utility model, at least a portion of the outer surface of the control panel 120 is a light-transmitting part 140, and the camera module 130 is disposed within the light-transmitting part 140. The light-transmitting part 140, in conjunction with its blocking function, ensures that the user will not come into contact with the camera module 130 body. This reduces the risk of malfunction due to accidental contact with the camera module 130 during use, and also facilitates cleaning of oil stains from the camera module 130.

[0046] In this embodiment, the light-transmitting part 140 is transparent glass.

[0047] In this embodiment, at least a portion of the outer surface of the control panel 120 is a light-transmitting part 140, and the camera module 130 is embedded in the control panel 120 and disposed on the light-transmitting part 140 of the control panel 120.

[0048] In some embodiments of this utility model, the image camera 133 is a color camera, and generating a color image can improve recognition accuracy.

[0049] In this embodiment, the camera module 130 is an image acquisition module that integrates a color camera and an infrared camera 132. It can acquire color and infrared images of the stove. After processing by the control module, it can sense the amount of smoke, the type of cookware used in the stove, the temperature of the burner, and the cooking method.

[0050] Please refer to Figure 4 In a further embodiment of this utility model, a range hood control module and a cooktop control module are also provided. The range hood control module is electrically connected to the camera module 130, the control panel 120, and the motor 200, respectively. The cooktop control module is electrically connected to the range hood control module. The cooktop control module includes a main cooktop control module and a switch detection module. The switch detection module is electrically connected to the main cooktop control module, and the main cooktop control module is electrically connected to the range hood control module. The switch detection module is a device or component used to detect the circuit switch of the cooktop. The switch detection module is electrically connected to the cooktop, so the cooktop control module can detect the working status of the cooktop through the switch detection module.

[0051] In some embodiments of this utility model, a first communication module is also provided, which is electrically connected to the control panel 120. The stove control module is further provided with a second communication module, which is electrically connected to the stove main control module. The wireless communication module composed of the first and second communication modules allows for wireless communication between the first and second communication modules. This enables timely reception of the stove's operating status. Simultaneously, the range hood can transmit stove burner image information, including but not limited to the type of stove used, cooking method and status, and burner temperature, to the stove control module, ensuring the immediacy of automatic control.

[0052] In this embodiment, a stove control module is provided. The stove control module detects the working status of the stove through a switch detection module. The switch detection module detects the working status of the stove by detecting the status of the solenoid valve, so as to realize the stove's precise monitoring of the combustion system. When the range hood detects that the solenoid valve of any burner is open, it can automatically turn on the fan for ventilation.

[0053] In some embodiments of this utility model, the module body 131 includes an upper controller panel 1311 and a lower camera panel 1312. The controller panel 1311 and the camera panel 1312 are connected by a connecting post 1313. The infrared camera 132 and the image camera 133 are connected to the lower side of the camera panel 1312. This is equivalent to the controller panel 1311 and the camera panel 1312 being relatively separate. The controller panel 1311 is used to install circuits and control chips, while the camera panel 1312 is used to fix the infrared camera 132 and the image camera 133, ensuring that the infrared camera 132 and the image camera 133 are fixed reliably, and also leaving enough installation space for the circuits and control chips.

[0054] In some embodiments of this utility model, the camera module 130 also integrates an image processing module. The image processing module is used to identify the temperature of the location corresponding to the detection range in the infrared thermal imaging and output a temperature parameter signal, and to identify the smoke situation image in the image and output a smoke parameter signal.

[0055] The stove according to the second aspect embodiment of this utility model is electrically connected to the range hood of the first aspect embodiment of this utility model. It includes several burners and a stove control module. Each burner has a solenoid valve installed on its gas pipe. The stove control module includes a main control module and a switch detection module.

The switch detection module is a device or component responsible for detecting the circuit switch of the stove. The switch detection module is electrically connected to the stove, allowing the stove control module to detect the stove's operating status.

[0056] According to the embodiments of this utility model, the cooktop uses the above-mentioned range hood, and in conjunction with the cooktop control module, detects and controls the working status of the cooktop, so that the range hood can be turned on simultaneously when the cooktop is working, thereby improving the user experience.

[0057] In some embodiments of this utility model, the switch detection module may be a switch monitoring device.

[0058] In some embodiments of this invention, the switch detection module is a solenoid valve switch detection module, matched with a solenoid valve switch. Each burner gas pipe is equipped with a solenoid valve, connected to the main control module of the stove. The switch detection module detects the status of the solenoid valve and transmits this status to the control module via the main control module.

[0059] In some embodiments of this utility model, the stove control module is also equipped with an anti-dry-burning probe. Each burner is equipped with an anti-dry-burning probe, and several anti-dry-burning probes are electrically connected to the stove main control module.

[0060] In this embodiment, each burner is equipped with an anti-dry-burning probe, which is connected to the main control module of the stove. The control module transmits the data, including the type of cookware used, the burner temperature, and the cooking method, to the main control module of the stove via the camera module 130. The main control module of the stove combines these three signals with the temperature signal from the anti-dry-burning probe to achieve a precise and intelligent anti-dry-burning function.
