[0002] A pellet oven is an oven that uses wood pellets as fuel. The main fuel for a pellet oven is wood pellets, which are compressed from wood or other plant waste. They usually do not contain chemical additives, making them more environmentally friendly. Pellet ovens are commonly used for home grilling. They provide a uniform heat source, ensuring that food is grilled evenly and adding a unique smoky flavor. They can grill a variety of meats, vegetables, and pizzas, etc. They are also widely used in commercial kitchens, especially in situations that require large-volume cooking and precise temperature control, such as restaurants and barbecue shops.

[0003] During the use of an oven, a controller is needed to control the oven's heat and temperature. However, current oven controllers are directly exposed, making them susceptible to electromagnetic interference, which can reduce the accuracy of adjustments and cause damage and waste of the food inside.

[0028] Example 1

[0029] Reference Figures 1 to 3 This is the first embodiment of the present invention, which provides an electromagnetic shielding structure for a pellet oven controller, comprising:

[0030] Control panel 100, with a knob 101 on one side for adjusting the size, and a display screen 103 on the other side;

[0031] The shielding mechanism 200 is used to shield electromagnetic interference. The shielding mechanism 200 includes a first shielding box 201 and a shielding box assembly 202. Both the first shielding box 201 and the shielding box assembly 202 are provided with a metal shielding mesh 203. The first shielding box 201 is provided with a filter 204 for filtering high-frequency noise on the power line.

[0032] The first shielding box 201 is made of metal materials such as aluminum, copper, and steel. It can not only reflect electromagnetic waves, but also guide external electromagnetic interference out, reducing the impact on the internal circuit. The metal shielding mesh 203 is a mesh structure made of metal wires, which can effectively block electromagnetic waves of different frequencies, especially when high-frequency electromagnetic wave shielding is required. The filter 204 includes, but is not limited to, low-pass filters or common-mode filters, which can effectively reduce high-frequency noise on the power line, thereby protecting the electromagnetic compatibility of the controller.

[0033] In use, the first shielding box 201 and the shielding box assembly 202 are fixed to the outer surface of the control panel 100. With the help of the metal shielding mesh 203, the interference of external electromagnetic waves can be reduced. The components inside the control panel 100 can reduce the electromagnetic waves generated during the transmission of current or signals through the filter 204, thereby reducing electromagnetic wave interference.

[0034] Example 2

[0035] Reference Figure 2This is the second embodiment of the present invention. Unlike the previous embodiment, the lower end of the knob 101 is provided with a light-emitting platform 102, and the control panel 100 is provided with a central processing unit 104. The central processing unit 104 is connected to the display screen 103, the knob 101 and the light-emitting platform 102 via cables, and the cables are shielded to reduce electromagnetic interference.

[0036] The central processing unit 104 can receive the adjustment signal transmitted by the knob 101 and make corresponding adjustments according to the signal. At the same time, it inputs the signal data into the display screen 103 for display. The cable uses shielded cable, such as a signal cable with a metal braided layer or a conductive plastic layer, to reduce electromagnetic interference. The light-emitting platform 102 can distinguish the size of the light source by color, such as the higher the temperature, the redder the color.

[0037] The filter 204 is connected to the central processing unit 104, the knob 101, and the light-emitting platform 102. One end of the filter 204 passes through the first shielding box 201 and is connected to the power line.

[0038] Filter 204 can handle electromagnetic waves generated by the power of internal components, reducing them to a minimum and improving the protection effect.

[0039] When in use, the device can be turned on and adjusted by rotating the knob 101. During adjustment, the size is distinguished by the color of the light source 102, and the display screen 103 can display the data during adjustment for convenient and precise adjustment.

[0040] Example 3

[0041] Reference Figure 1 and Figure 3 This is the third embodiment of the present invention. Unlike the previous embodiment, the shielding box assembly 202 includes a second shielding box 2021. An observation window 2022 is provided on the outer surface of the second shielding box 2021. A transparent shielding film 2023 is fixedly connected inside the observation window 2022. A through hole 2024 is provided on the other side of the outer surface of the second shielding box 2021. The observation window 2022 is located on the outer surface of the display screen 103. A knob 101 passes through the through hole 2024. A sealing gasket 2025 is fixedly connected inside the through hole 2024 and is attached to the outer surface of the light-emitting platform 102. A protrusion 2026 is fixedly connected to the rear outer edge of the second shielding box 2021. A groove 206 is provided on one outer edge of the first shielding box 201, and the outer surface of the protrusion 2026 is attached to the inside of the groove 206. Both ends of the first shielding box 201 and the second shielding box 2021 are fixedly connected to a connecting plate 205. The connecting plate 205 and the outer surface of the control panel 100 are provided with mounting holes 105. The adjacent sides of the connecting plate 205 are attached to the outer surface of the control panel 100.

[0042] The second shielding box 2021, like the first shielding box 201, is made of metal materials such as aluminum, copper, and steel. It can not only reflect electromagnetic waves but also guide external electromagnetic interference out, reducing its impact on internal circuits. The transparent shielding film 2023 can use ITO film or indium tin oxide film to provide electromagnetic shielding. This transparent film can not only block electromagnetic waves but also allow sufficient light to pass through, thereby ensuring the clarity of the display screen 103. The sealing gasket 2025 is sealed with conductive rubber strips or conductive silicone sealing strips, which can not only ensure mechanical sealing but also help reduce electromagnetic wave leakage.

[0043] Furthermore, the metal shielding mesh 203 is symmetrically arranged on the side adjacent to the control panel 100 and the first shielding box 201 and the second shielding box 2021, and the outer surface of the control panel 100 is coated with conductive paint.

[0044] Conductive coatings include, but are not limited to, carbon black coatings and graphite coatings. Applying these coatings to the surface of the controller can form a conductive shielding layer, reducing the propagation of electromagnetic waves.

[0045] During use, the second shielding box 2021 and the first shielding box 201 can reflect external electromagnetic waves and reduce the entry of electromagnetic waves. At the same time, the metal shielding mesh 203 can effectively block electromagnetic waves of different frequencies, thereby reducing a portion of the electromagnetic waves a second time. When the remaining electromagnetic waves approach the control panel 100, the conductive coating can block them again, thereby minimizing electromagnetic interference, reducing interference to the use of the device and improving the effect of use.

[0046] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
