Description

Technical Field

[0001] The utility model relates to the technical field of cooking appliances, and more specifically, to an induction cooking appliance. Background Art

[0002] The induction cooking appliance disclosed in the Chinese patent with the publication number CN221099897U includes a cooking main body, an infrared temperature measurement module, and a light-shielding body with a light channel. The cooking main body has a glass panel for placing a cooking pot and a heating wire coil disposed below the glass panel; the infrared temperature measurement module includes an indium gallium arsenide infrared detection head and a circuit board, and the indium gallium arsenide infrared detection head is installed on the circuit board and electrically connected thereto; both ends of the light channel are respectively in close contact with the glass panel and the infrared temperature measurement module, and the light-shielding body has a fixing portion connecting the heating wire coil.

[0003] The above solution increases the light-shielding effect of the induction cooking appliance by providing a light-shielding body with a light channel, and prevents foreign matters such as insects and oil stains from covering the detection head and causing attenuation of the infrared signal. However, 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, resulting in poor heat dissipation inside, the temperature inside the cavity will rise, and a higher temperature inside the cavity will reduce the service life of the infrared temperature measurement module detector.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide an induction cooking appliance.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: an induction cooking appliance includes a glass panel assembly, an infrared temperature measurement module, and a heating wire coil. A light-shielding member is detachably connected to the heating wire coil. The light-shielding member is provided with an upper opening and a lower opening, and a through hole communicating the upper opening and the lower opening is provided on the light-shielding member. The upper opening faces the direction of the glass panel assembly, and the lower opening can accommodate at least part of the infrared temperature measurement module. When the infrared temperature measurement module is located in the lower opening, there is an air flow channel between the infrared temperature measurement module and the inner wall of the lower opening.

[0007] The present utility model is further provided that when the infrared temperature measurement module is located in the lower opening, there is a gap between the infrared temperature measurement module and the inner wall of the lower opening.

[0008] The present utility model is further provided that a groove is recessed on the outer peripheral wall of the light-shielding member, and a convex ring that can be embedded in the groove is provided on the heating wire coil. The light-shielding member and the heating wire coil are fixed by the convex ring being embedded in the groove.

[0009] The present utility model is further configured as follows: The light-shielding member includes a connecting portion, a limiting portion, and a protecting portion. The limiting portion and the protecting portion are respectively arranged at two ends of the connecting portion. The upper opening is formed on the limiting portion, the lower opening is formed on the protecting portion, and the widths of both the limiting portion and the protecting portion are greater than the width of the connecting portion.

[0010] The present utility model is further configured as follows: The light-shielding member has elastic recovery characteristics.

[0011] The present utility model is further configured as follows: The light-shielding member is made of silica gel or rubber.

[0012] The present utility model is further configured as follows: A limiting groove for accommodating the embedding of the limiting portion is formed on the top surface of the heating wire coil, and the cross-section of the limiting portion is circular.

[0013] The present utility model is further configured as follows: When the light-shielding member is fixed to the heating wire coil, there is a gap or a tight fit between the light-shielding member and the glass panel assembly.

[0014] The present utility model is further configured as follows: The infrared temperature measurement module includes an indium gallium arsenide infrared detection head, and the photosensitive surface of the indium gallium arsenide infrared detection head faces the upper opening.

[0015] The present utility model is further configured as follows: A protective shell is provided on the indium gallium arsenide infrared detection head, and the protective shell filters light in a wavelength band of ≤0.94 μm.

[0016] In summary, the present utility model has the following beneficial effects: Since there is a gap between the light-shielding member and the infrared temperature measurement module, the gap can reduce the heat transferred from the heating wire coil to the infrared temperature measurement module. The air circulation is realized through the through holes, which can effectively improve the heat dissipation efficiency in the sealed cavity and reduce the temperature in the cavity. The reduction of the temperature in the cavity helps to reduce the loss of the infrared temperature measurement module caused by overheating, thereby prolonging its service life. By setting the light-shielding member and the upper opening of the light-shielding member facing the direction of the glass panel assembly, the interference of the interfering light on the accuracy of the infrared temperature measurement module can be reduced, and at the same time, foreign matters such as insects and oil stains can be prevented from directly covering the infrared temperature measurement module, reducing the attenuation of the infrared signal. Since the light-shielding member is detachably connected, it is convenient for the operator to clean and maintain, keeping the accuracy of the infrared temperature measurement module. At the same time, the elastic recovery characteristics of the light-shielding member help to maintain the structural stability during the installation and disassembly process, reducing the damage caused by improper installation.

Detailed implementation manners

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 of the present utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application in this specification are only for the purpose of describing specific embodiments, and are not intended to limit this application.

[0026] Next, the present utility model will be described in detail in conjunction with the accompanying drawings and embodiments.

[0027] An induction cooking appliance, as shown in the figure, includes a cooking main body 1, an infrared temperature measurement module 2, and a heating coil 12. Specifically, the cooking main body 1 includes a glass panel assembly and a lower cover. Both the infrared temperature measurement module 2 and the heating coil 12 are arranged inside the cooking main body 1. This integrated design makes the whole device more compact, saves space, and protects the infrared temperature measurement module 2 and the heating coil 12 from the direct influence of the external environment, reducing the interference of external light sources and environmental factors on the accuracy of the infrared temperature measurement module 2.

[0028] A light-shielding member 3 with elastic recovery characteristics is detachably connected to the heating coil 12. Specifically, the light-shielding member 3 is made of silicone or rubber. Both silicone and rubber have good elasticity, good heat resistance, and are light-tight. The elastic characteristics of silicone and rubber make the light-shielding member 3 more convenient to install and disassemble, can adapt to heating coils 12 of different shapes and sizes, and can still maintain its shape after repeated use. At the same time, both of these materials can withstand the high temperatures that may be generated during the cooking process and are not easily aged or damaged due to temperature changes. Further, the light-tightness of silicone and rubber can effectively block external light sources, reduce the interference with the infrared temperature measurement module 2, and improve the accuracy of temperature measurement.

[0029] An upper opening 5 and a lower opening 6 are provided on the light-shielding member 3. A through hole 7 communicating the upper opening 5 and the lower opening 6 is provided on the light-shielding member 3. The upper opening 5 faces the direction of the glass panel assembly. The lower opening 6 can accommodate at least part of the infrared temperature measurement module 2. When the infrared temperature measurement module 2 is located in the lower opening 6, there is an air flow channel between the infrared temperature measurement module 2 and the inner wall of the lower opening 6. Specifically, there is a gap between the infrared temperature measurement module 2 and the inner wall of the lower opening 6. Since there is a gap between the light-shielding member 3 and the infrared temperature measurement module 2, the gap can reduce the heat transferred from the heating coil 12 to the infrared temperature measurement module 2. Air circulation is achieved through the through hole 7, which can effectively improve the heat dissipation efficiency in the sealed cavity, reduce the temperature in the cavity. The reduction of the temperature in the cavity helps to reduce the loss of the infrared temperature measurement module 2 caused by overheating, thereby extending its service life. By setting the light-shielding member 3 and the upper opening 5 of the light-shielding member 3 facing the glass panel direction, the interference of interfering light on the accuracy of the infrared temperature measurement module 2 can be reduced. At the same time, it can also prevent foreign matters such as insects and oil stains from directly covering the infrared temperature measurement module 2, reducing the attenuation of the infrared signal. Further, when the light-shielding member 3 is fixed to the heating coil 12, there is a gap or close fit between the light-shielding member 3 and the glass panel assembly. When there is a gap between the two, the gap can serve as a channel for air circulation to help with heat dissipation and avoid heat accumulation between the light-shielding member 3 and the glass panel assembly. When the two are closely fitted, the infrared light emitted by the cookware can pass through the panel and directly irradiate the infrared detector head, making the infrared temperature measurement module 2 more accurate when measuring temperature.

[0030] Further, an embedding groove 8 is formed by recessing on the outer peripheral wall of the light-shielding member 3. A convex ring 9 that can be embedded in the embedding groove 8 is provided on the heating wire coil 12. The light-shielding member 3 and the heating wire coil 12 are fixed by embedding the convex ring 9 into the embedding groove 8. Specifically, the light-shielding member 3 includes a connecting portion 10, a limiting portion 11, and a protecting portion 4. The limiting portion 11 and the protecting portion 4 are respectively arranged at both ends of the connecting portion 10. An upper opening 5 is formed on the limiting portion 11, and a lower opening 6 is formed on the protecting portion 4. The widths of both the limiting portion 11 and the protecting portion 4 are greater than the width of the connecting portion 10. The design of embedding the convex ring 9 into the embedding groove 8 provides a mechanical locking mechanism, ensuring that the light-shielding member 3 is not easily loosened on the heating wire coil 12. At the same time, through the cooperation of the convex ring 9 and the embedding groove 8, the light-shielding member 3 can be conveniently installed and disassembled, facilitating maintenance and cleaning.

[0031] A limiting groove 13 that can accommodate the embedding of the limiting portion 11 is formed on the top surface of the heating wire coil 12. The cross-section of the limiting portion 11 is circular. By providing the limiting groove 13, the limiting groove 13 can ensure the position of the light-shielding member 3, preventing it from shifting horizontally, ensuring the position of the through hole 7, and preventing the through hole 7 from shifting. Furthermore, it ensures the consistency of the signal intensity of the infrared rays of the cookware irradiating on the indium gallium arsenide infrared detector. At the same time, due to the tight fit between the limiting portion 11 and the limiting groove 13, errors caused by improper installation can be reduced, improving the temperature measurement accuracy.

[0032] The infrared temperature measurement module 2 includes an indium gallium arsenide infrared detection head. Compared with a 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 photosensitive surface of the indium gallium arsenide infrared detection head faces the upper opening 5. The infrared light emitted by the cookware passes through the panel and irradiates on the infrared detection head. A protective shell 14 is provided on the indium gallium arsenide infrared detection head. The protective shell 14 can filter light in the wavelength band ≤0.94μm, which can reduce the interference of visible light and near-infrared light on the infrared detector, further improving the measurement accuracy. At the same time, by reducing unnecessary light interference and providing physical protection, the service life of the indium gallium arsenide infrared detection head can be extended.

[0033] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
