[0003] Since the light-shielding body, the panel, and the infrared temperature measurement module are in close contact with each other, a sealed cavity is formed, causing the temperature inside the cavity to rise. To reduce the temperature inside the cavity, a number of symmetric heat dissipation holes are usually provided on both sides of the housing. However, the setting of the heat dissipation holes allows external interfering light to pass through the heat dissipation holes and enter the interior of the housing, interfering with the infrared temperature measurement module and affecting the accuracy of its detection.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

It is only for the convenience of describing the present utility model, rather than indicating that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0021] The present utility model will be described in detail below with reference to the drawings and embodiments.
[0022] An induction cooking appliance, as Figure 1 shown, includes a housing 1, a heating wire coil 3, and an infrared temperature measurement module 2. The heating wire coil 3 and the infrared temperature measurement module 2 are both arranged inside the housing 1. The housing 1 can provide physical protection to prevent the intrusion of dust, moisture, and other pollutants, and extend the service life of the device. Specifically, the housing 1 includes a lower cover 4 and a glass panel assembly 5. The glass panel assembly 5 includes a glass plate and a plastic ring arranged along the outer edge of the glass plate. The plastic ring is bonded to the glass plate. At the same time, the plastic ring is detachably connected to the lower cover 4. The glass plate is a microcrystalline panel, which has the characteristics of high temperature resistance and wear resistance, enabling it to remain stable in a high-temperature environment and also being able to resist scratches and impacts during daily use, extending the service life of the product.
[0023] Heat dissipation holes are provided on the side wall of the lower cover 4. A rib 6 is provided on the lower cover 4. The rib 6 encloses a closed or semi-closed area. Specifically, the opening of the semi-closed area enclosed by the rib 6 faces away from the heat dissipation holes. The infrared temperature measurement module 2 is located in the light-shielding area formed by the rib 6 and the height of the rib 6 is greater than or equal to the height of the infrared temperature measurement module 2 after installation. At the same time, the material of the rib 6 is a light-impermeable material. The heat dissipation holes on the side wall of the lower cover 4 can effectively dissipate the heat inside the housing 1, prevent the internal components from overheating, and maintain the normal operation of the device. By setting the rib 6 and arranging the infrared temperature measurement module 2 in the light-shielding area formed by the rib 6, it is possible to block the interference light from the heat dissipation holes on the side from directly irradiating the detector, reducing interference and ensuring the detection accuracy of the detector. At the same time, since the height of the rib 6 is greater than or equal to the height of the infrared temperature measurement module 2 after installation, while achieving the light-shielding effect, it also provides additional physical protection for the infrared temperature measurement module 2. Since the rib 6 is made of a light-impermeable material, it further ensures that the infrared temperature measurement module 2 is not interfered by external light sources, guaranteeing the accuracy of the measurement.
[0024] A number of positioning posts 7 are fixedly connected to the lower cover 4. The infrared temperature measurement module 2 is provided with mounting holes. The infrared temperature measurement module 2 and the positioning posts 7 are detachably connected. Specifically, the infrared temperature measurement module 2 includes an indium gallium arsenide infrared detector head. The photosensitive surface of the indium gallium arsenide infrared detector head faces the glass panel assembly. The infrared light emitted by the cookware passes through the panel and irradiates onto the infrared detector head. The retaining rib 6 and the positioning posts 7 are integrally formed on the lower cover 4. The integrally formed design provides the connection strength between the retaining rib 6 and the positioning posts 7 and the lower cover 4, and also reduces the additional steps and materials in the assembly process, thereby reducing the production cost. Compared with the pyroelectric infrared detector, the indium gallium arsenide infrared detector has the characteristics of being able to measure temperature through glass and having strong resistance to water, water vapor, soft tissues and other objects. The detachable connection design between the infrared temperature measurement module 2 and the positioning posts 7 makes the installation and maintenance more convenient, and the infrared temperature measurement module 2 can be quickly replaced or upgraded. Of course, the implementation mode of the present invention is not limited to this. The positioning posts 7 and the retaining rib 6 can be separate accessories. By adding some bumps on the positioning posts 7 and the retaining rib 6 and opening some grooves on the lower cover 4 to accommodate the bumps, the positioning posts 7 and the retaining rib 6 can also be snapped onto the lower cover 4 to enhance the connection strength between them and ensure their stability during use.
[0025] Furthermore, a number of screws and threaded holes matching the screws are provided on the positioning posts. The infrared temperature measurement module and the positioning posts are fixed by passing the screws through the mounting holes and screwing them into the threaded holes. Through the cooperation of the screws and the threaded holes, it can be ensured that the position of the infrared temperature measurement module in the cooking appliance is very stable, preventing the infrared temperature measurement module from shifting, ensuring the stability of the infrared temperature measurement module during the temperature measurement process, and the design of using screws and threaded holes simplifies the installation process, making the installation and disassembly of the infrared temperature measurement module easy and facilitating maintenance and replacement. Of course, the implementation mode of the present invention is not limited to this. In other embodiments, a limiting post and a limiting block can also be provided on the top surface of the positioning post. The limiting post can pass through the mounting hole, and at the same time, the width of the limiting block is greater than the width of the mounting hole. When installing, the operator can install the infrared temperature measurement module onto the lower cover by pressing, so that the two are in interference fit, thereby ensuring the stability of the infrared temperature measurement module during temperature measurement and preventing loosening caused by vibration or impact, improving the use safety.
[0026] When the infrared temperature measurement module 2 is fixed to the positioning posts 7, there is a gap between the infrared temperature measurement module 2 and the heating wire coil 3. The gap can be used as a thermal insulation measure to prevent the high temperature of the heating wire coil 3 from directly affecting the infrared temperature measurement module 2, thereby protecting the infrared temperature measurement module 2 from overheating damage. By preventing the high temperature from directly acting on the infrared temperature measurement module 2, the service life of the infrared temperature measurement module 2 can be extended. At the same time, the gap can be used as a channel for air circulation, which helps to achieve a heat dissipation effect.
[0027] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
