Description

Technical Field

[0001] This utility model relates to the technical field of ventilation in household appliances, specifically to a ventilation assembly and an appliance or induction cooker having the assembly. Background Technology

[0002] In the current home appliance market, the core function of devices such as vacuum cleaners and air purifiers is to purify the air through their exhaust assemblies. User experience research shows that allowing users to directly and in real-time understand changes in air cleanliness during the suction process would optimize the user experience.

[0003] On the other hand, as a common kitchen appliance, induction cookers often produce cooking fumes such as oil fumes and steam when heating cookware. Currently, most induction cooker products on the market lack the ability to process these fumes, requiring users to turn on a range hood, which is inconvenient in some compact kitchen environments or simple cooking scenarios.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0025] First embodiment: See Figures 1-4 An exhaust assembly includes an air inlet 101, an air inlet channel 102, and a fan 2 disposed on a body 1. The air inlet 101, the air inlet channel 102, and the air inlet end and the air outlet end of the fan 2 are connected in sequence to allow the fan 2 to draw in external gas from the body 1. Electronic components 3 are disposed in the inner circumference of the body 1 corresponding to the air inlet channel 102.

[0026] When the exhaust assembly is applied to an induction cooker, the electronic component 3 (electromagnetic coil heating plate) is located inside the air intake channel 102, and the heating area of ​​the heating coil is relatively large. The exhaust assembly can quickly draw in the oil fumes and water vapor generated during cooking, filter them, and then discharge them into the outside air. The upper part of the body 1 is equipped with a filter (such as activated carbon) for filtering and purifying the air. When the pot is placed on the heating surface of the induction cooker, since the bottom of the pot does not completely cover the induction cooker, the air intake 101 and the filter are not blocked. Even if they were blocked, the gas can still enter the filter through the corresponding gap and then enter the air intake channel 102 from the air intake 101.

[0027] The main control circuit board inside the machine body 1, electronic components 3, and fan 2 are electrically connected to the main control circuit board. The main control circuit board can dynamically adjust the speed of fan 2 according to the power of the heating coil (corresponding to the cooking heat).

[0028] The electronic component 3 is a heating element, specifically an electromagnetic coil heating plate.

[0029] The furnace body is provided with an electrical compartment 106 for installing circuit board electrical components. A partition 107 is provided between the electrical compartment 106 and the air inlet channel 102. The electrical compartment 106 and the air inlet channel 102 are spaced apart. The partition 107 forms a barrier structure to prevent oil fumes from entering the electrical compartment 106 and to prevent oil fumes from contaminating the electrical components inside the electrical compartment 106.

[0030] The air inlet channel 102 is located above the fan 2 and has an output end that is far away from the electrical components. The output end is connected to the electrical compartment 106. When the fan 2 is running, it can absorb the heat from the electrical components in the electrical compartment 106.

[0031] The upper air intake area of ​​the main body 1 has a ring-shaped structure to form a 360-degree suction structure on the main body. The electronic components 3 are located within the inner perimeter of the ring-shaped air intake area of ​​the main body 1, without affecting the setting of the electromagnetic coil heating plate. The exhaust assembly is integrated into the induction cooker. The 360-degree ring-shaped air intake area can fully cover the upper part of the cooker body, increasing the air intake area. Together with the upper filter, it can quickly capture the oil fumes and water vapor scattered around the pot (even if the bottom of the pot is not completely covered, or partially blocked, the gas can still enter the filter through the gaps).

[0032] The upper part of the body 1 has a number of circumferentially spaced partition blocks 104 in the suction area, and a number of spaced air inlets 101 are provided on the upper part of the body 1.

[0033] The separation block 104 forms three or more air inlets 101, which can make the gas enter the upper filter evenly and avoid insufficient filtration caused by excessive local airflow.

[0034] The air outlet 103 and the fan 2 are respectively located on the bottom of the body 1. The fan 2 and the air outlet are located at the bottom, so that the filtered clean gas is discharged from the bottom, achieving purification and smoke removal.

[0035] The fan 2 can be fixed to the bottom of the body 1 with screws.

[0036] The body 1 has a mounting cavity 105 for mounting electronic components 3. The upper air intake area of ​​the body 1 has a ring-shaped structure, and the mounting cavity 105 is located inside the ring-shaped air intake area and the air intake channel 102 of the body 1.

[0037] The air inlet channel 102 is annular and is located inside the body 1, and the air inlet end of the fan 2 is located below the output end of the air inlet channel 102.

[0038] An induction cooker includes a cooker body, on which the above-mentioned exhaust assembly is provided, and at the bottom of the cooker body is an air outlet 103 connected to the air outlet end of a ventilation fan 2.

[0039] Second embodiment: See Figures 5-9 The electrical appliance differs from the first embodiment in that the main body of the appliance is a vacuum cleaner or an air purifier, and the above-mentioned exhaust assembly is provided on the main body of the appliance.

[0040] The electronic component 3 is a camera 301 and / or a sensor 302 used for monitoring.

[0041] An air filter is installed on the upper part of the unit 1 corresponding to the air inlet 101. Sensors such as a camera 301, infrared sensor, and lidar (laser dust sensor, infrared dust sensor) are used to detect the cleanliness of the target object. The camera 301 can observe whether there is dust or impurities in the filtered air, while the infrared sensor and lidar are used to detect the cleanliness of the gas. The cleanliness level is displayed digitally on the display screen of the unit 1, providing a visual representation to the user. The image from the camera 301 can be transmitted to the user's mobile phone via Bluetooth, also achieving visual representation.

[0042] The probes of the laser dust sensor and the infrared dust sensor extend into the air inlet channel 102, and the shooting area of ​​the camera 301 faces the air inlet channel 102.

[0043] The multi-camera stitching solution works by installing two or more ultra-wide-angle fisheye cameras on the same plane. Each camera is responsible for capturing a field of view exceeding 180 degrees.

[0044] Alternatively, a rotating camera solution can be used. The working principle is as follows: The main body 1 contains only one camera, and a rotating platform is located inside the main body 1, driven by a motor. The camera rotates one revolution.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
