Description

Technical Field

[0001] This invention relates to the field of cooking equipment technology, and in particular to an electric heating cooking appliance with a dedicated connection structure between a heating plate temperature measuring element and an electric heating plate. Background Technology

[0002] Commonly known electric cooking appliances control the cooking process entirely based on the container temperature detected by sensors, without knowing the temperature of the heating plate. This is achieved by adjusting the heating plate's power or switching the power on / off. The dedicated device for detecting and controlling the heating plate temperature is a snap-action thermostat located on the bottom of the heating plate. Because snap-action thermostats only have the characteristic of switching on at low temperatures and off at high temperatures, they do not provide the appliance with the heating plate's temperature data. Therefore, snap-action thermostats are mostly used for heat preservation or overheat protection, and do not participate in the appliance's control of the cooking process. Summary of the Invention

[0003] This invention aims to provide a heating plate temperature measuring device with a thermoelectric electrode as the temperature-sensitive element. Through the thrust generated by the push plate assembly, it reliably connects with the heating plate and uses a dedicated temperature detection structure for the heating plate to ensure that the appliance obtains stable and consistent heating plate temperature data. This data serves as an important parameter for the appliance's cooking control. Combined with different container materials, cooking ingredients, and cooking conditions, it enables targeted adjustment of the heating plate power or power supply on / off for cooking control, thereby solving the problems existing in known electric heating cooking appliances and expanding the appliance's application scenarios.

[0004] The technical solution of the present invention is a temperature measuring structure for an electric heating plate, characterized in that it includes:

[0005] The heating plate has a recessed hole in the middle, the main body has a sensor with a flip-up buckle inserted from the recessed end, a protruding edge placed in the recessed stage, a heating plate temperature measuring element set between the protruding edge and the recessed stage, and a push plate assembly that combines the sensor, the heating plate temperature measuring element and the heating plate together.

[0006] A heating plate temperature measuring device, comprising: a heat-conducting sheet, a working end fixed on the heat-conducting sheet, and a thermoelectric electrode for collecting temperature data of the electric heating plate using the Seebeck effect;

[0007] A push plate assembly, comprising: a push plate having screw holes and a central hole, and screws disposed on the push plate that abut against the heating plate.

[0008] Furthermore, the heating plate is flat or concave-convex, and is a resistance wire or heating film type heating device.

[0009] Furthermore, the aforementioned hot plate temperature measuring element and sensor are either independent devices or combined components.

[0010] Furthermore, the hot plate temperature measuring element is provided with a protective component and / or an electromagnetic shield between the working end and the free end. The working end of the S, R, B, N, E, T, J, K type thermoelectric electrode is connected to the annular or sheet-shaped heat-conducting plate by welding, riveting, screws, or clamping.

[0011] Furthermore, the aforementioned buckles are two or more protruding edges set on the top of the sensor body, or two or more buckles with three sides suspended in the middle of the sensor body.

[0012] The beneficial effects of this invention are that, since the thermistor fixed on the heat-conducting plate is a thermoelectric electrode, and the heat-conducting plate is stably and reliably clamped to the sink of the heating plate by the thrust generated by the push plate assembly through the convex edge of the sensor; therefore, the heating plate temperature measuring element can not only improve the operating temperature of the heating plate, but also continuously acquire the heating plate temperature during the cooking process, providing accurate and stable heat source temperature control basis for the appliance, and rationally adjusting the heating plate power or power supply on / off according to different functions, containers, temperatures, and ingredients, thereby effectively solving the problem of existing electric heating cooking appliances that only adjust the heating plate power or power supply on / off based on the container temperature. Other effects will be set forth in part in the description which follows, and in part will become apparent from the following description, or may be learned from practice of the invention.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Examples of the embodiments are shown in the drawings. The described embodiments are exemplary, wherein similar reference numerals denote the same or similar devices, or devices having the same or similar functions. The terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the drawings and are merely for the convenience of describing the present invention and simplifying the description. They are not intended to 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 the present invention.

[0022] This invention involves the explanation of concepts. "Abutting": "Abutting" refers to squeezing, pushing, pressing, or pressing with force; "connecting" means linking. "Abutting" refers to a connection method where two or more devices are squeezed, pushed, pressed, or pressed together by forces generated in different ways to form a fixed or movable connection. "Clamping": This is a verb meaning to fix or control an object in a certain position by "clamping". "Snap-on": This refers to the mechanical feature on a known magnetic steel thermostat where the thermostat is pried out on three sides and abuts against the heating plate, thus mounting the magnetic steel thermostat on the heating plate. Terms such as "sunken hole," "sunken platform," and "protruding edge" should be interpreted broadly based on known technology and the description herein, unless otherwise explicitly specified and limited. Therefore, those skilled in the art can understand the meaning of the above terms in this invention according to the specific circumstances.

[0023] The following is for reference. Figures 1 to 7 The present invention describes a temperature measuring structure for an electric heating plate.

[0024] The technical solution of the present invention is a temperature measuring structure for an electric heating plate, characterized in that it comprises:

[0025] The device features a central recessed platform, which can be flat or concave-convex, housing a resistance wire or heating film type heating plate. The main body has a snap-fit ​​mechanism that inserts from the recessed platform end. A raised edge is positioned within the platform, either below or flush with the upper surface of the heating plate. A sensor for detecting container temperature is located between the raised edge and the platform. A pusher assembly uses thrust to securely and reliably clamp and fix the heated plate temperature sensor onto the platform of the heating plate, thus combining the sensor, heated plate temperature sensor, and heating plate together. Since the container rests on the upper surface of the heating plate, the temperature data detected by the heated plate temperature sensor changes rapidly with variations in the heating plate's power or power supply switching, as well as changes in the container temperature. This allows the device to combine the detected container temperature with the power... The device allows for targeted control of the heating plate's power or power supply. Furthermore, the heating plate temperature sensor and the sensor in the described technical solution are independent devices or combined components, having no impact on the heating plate's temperature detection. Even when only the heating plate's temperature needs to be controlled, the technical solution can simplify the sensor into a pressure plate with a screw in the middle, and the push plate assembly into a clamping plate with a screw hole. An independent heating plate temperature sensor or thermoelectric electrode is used, and the working end of the heating plate temperature sensor or thermoelectric electrode is clamped onto the heating plate's recess using the pressure plate and clamping plate fitted on both sides of the heating plate's recessed hole. Since the simplified solution is easily understood by those skilled in the art, it is not illustrated in the accompanying drawings.

[0026] Furthermore, the heating plate temperature measuring element includes: an annular or sheet-shaped heat-conducting sheet, the working end of which is welded, riveted, screwed, or clamped and fixed to the heat-conducting sheet, and the heating plate temperature data is collected using the Seebeck effect. A protective component and / or an electromagnetic shield is provided between the working end and the free end. It also includes S, R, B, N, E, T, J, and K type thermoelectric electrodes. Furthermore, if appearance is not a concern and economy is the priority, the working end of the thermoelectric electrode can be directly set between the sensor protrusion and the heating plate recess.

[0027] Furthermore, the push plate assembly includes: a push plate with two or more screw holes and a central hole larger than the outer dimension of the sensor body, which abuts against two or more protruding edges on the top of the sensor body after being bent outwards to form flip-out buckles; or a push plate abutting against two or more clips on the middle of the sensor body after being pried outwards to form flip-out buckles; and two or more screws on the push plate that abut against the heating plate. When the adjusting screw increases the distance between the push plate and the bottom surface of the heating plate, the push plate will gradually abut against the bent protruding edges or the pried-out clips. As the screw adjustment depth increases, the push plate will increase the clamping force of the heat-conducting sheet through the protruding edge and the countersunk platform, so that the heating plate temperature measuring component can be clamped between the protruding edge and the countersunk platform for a long time, reliably and stably. Therefore, the above technical solution not only prevents the rotation of the sensor, but also avoids the inconsistency of the known magnetic steel temperature controller clips when pried out, as well as the impact of high and low temperature cross-changes on the clamping and fixing life of the heating plate temperature measuring component after use.

[0028] Therefore, the aforementioned electric heating appliance is suitable for household or commercial use: electric rice cooker, electric pressure cooker, electric slow cooker, electric steamer, electric multi-purpose cooker, air fryer, health pot, multi-purpose electric stove and other cooking appliances.
