Some embodiments according to the present utility model are described below with reference to fig. 1 to 7.

As shown in fig. 1, the temperature measuring assembly 100 provided in this embodiment mainly includes a carrying plate 102, a heat conducting sheet 104, a heating coil 202 and a temperature sensing member 106, where the carrying plate 102 is used for carrying a cooking appliance, and the heat conducting sheet 104 is disposed on one side of the carrying plate 102, specifically, the side far away from the cooking appliance, i.e. the outer surface of the carrying plate 102 is used for carrying the cooking appliance, and the heat conducting sheet 104 is disposed on one side of the inner surface, so that heat can be transferred to the temperature sensing member 106 through the heat conducting sheet 104, and finally, the Wen Ganjian is convenient for detecting the temperatures of the heat conducting sheets 104 at different positions, i.e. detecting the temperatures in specific areas on the first side of the carrying plate 102. In particular, in the present utility model, the temperature sensing element 106 is disposed below the heat conducting plate 104, and the Wen Ganjian is abutted against the heat conducting plate 104, so that the temperature on the carrying area 1022 is detected. It should be emphasized that, according to the present utility model, the heat conducting sheet 104 is used to transfer the heat on the carrier plate 102 to the temperature sensing element 106, so as to facilitate the temperature detection, and the heat conducting sheet 104 is used to attach to the carrier plate 102, so as to improve the accuracy of the temperature detection.

It should be emphasized that a heating coil 202 is further disposed on the lower side of the heat conducting plate 104, and the heating coil 202 can heat the cooking appliance placed on the carrier plate 102, so as to complete cooking of the food material in the cooking appliance. The projection of the heating coil on the bearing plate forms a first area, it can be understood that the heating effect of the heating coil 202 on different positions will be different, a certain heating range exists, in order to ensure more good heat conduction effect, the relative position between the heating coil 202 and the heat conducting sheet 104 is limited, namely, the heat conducting sheet 104 at least covers the efficient heating range of the heating coil 202, the efficient heating range is limited, an annular area exists on the bearing plate, the center of the annular area is the center point of the first area, the inner diameter of the annular area is 1/6 of the size of the first area in the first radial direction, the outer diameter of the annular area is 5/6 of the size of the first area in the second radial direction, the annular area formed under the range is the efficient heating range, the heating value of the cooking appliance in the position range is higher, and higher-power cooking can be realized.

Meanwhile, as the heating value of the position is higher, stress can be generated in the bearing plate due to temperature difference, so that the internal structure is broken, and the temperature can be measured in time through the arrangement of the heat conducting fin and the temperature sensing piece.

It should be noted that the first radial direction and the second radial direction may be the same direction or may be different directions.

Wherein the heat conducting sheet can be in a solid round sheet shape, the outermost end of the heat conducting sheet at the outermost end can exceed the outer ring of the wire coil or not,

the heat conductive sheet may also have an annular sheet shape, and the innermost end of the heat conductive sheet may be spaced apart from the center position or may extend to the center position.

It should be added that the annular region is concentric with the first region of the heating coil 202, and on this basis, by limiting the projection of the heat conducting strip 104, the overlap with the heating coil 202 is limited, so that the cooking effect of the heating coil 202 with higher power can be fully utilized, and the use experience can be improved.

Further, the bearing plate 102 is disposed at the uppermost part of the whole temperature measuring assembly 100, the first side is used for bearing a cooking appliance, and when the cooking appliance is in operation, local dry heating may occur, at this time, heat is transferred to the temperature sensing piece 106 through the heat conducting sheet 104 located at the second side of the bearing plate 102, and the temperature at a specific position can be detected by using the offset position relationship between Wen Ganjian and the heat conducting sheet 104, so that the temperature of each part of the bottom of the pot is accurately measured, the cooking experience is ensured, and further, the operation of a product can be controlled according to specific temperature change, and the effect of effectively protecting the panel is achieved.

It can be appreciated that by using a plurality of temperature sensing members 106, the temperature of a specific area on the carrier plate 102 can be accurately and rapidly measured, so that the temperature in different temperature measuring areas can be detected by the subsequent control panel, and thus the temperature control can be realized.

In this embodiment, the first side of the carrying plate 102 is formed with a carrying area 1022, generally an upper surface, that is, the cooking appliance can only be placed on the designated carrying area 1022, so as to achieve a better cooking effect.

Further, on the basis of any of the above embodiments, the heat conducting fin is flexibly assembled, for example, the heat conducting fin is installed on a heating wire coil, and the heat conducting fin can also be installed on an upper cover bracket, or assembled on a surface cover, or assembled on a temperature sensing piece.

The heat conducting fin and the heat insulating member may be integrally formed, and the heat conducting fin may extend beyond the outer ring of the heating coil.

As shown in fig. 5, a plurality of identical heat conducting areas are connected into a ring-shaped heat conducting sheet through distal ends, and the heat conducting sheet has an opening at the edge and may not have an opening, and when the material of the heat conducting sheet can be electromagnetically heated, the heat conducting ring formed by the heat conducting sheet needs to be opened, and when the material of the heat conducting sheet cannot be electromagnetically heated, the heat conducting ring formed by the heat conducting sheet may or may not be opened.

It should be noted that, when the heat conducting strip 104 is made of a magnetizable material, for example, iron, cobalt, nickel, or an alloy thereof, if the plurality of heat conducting areas 1044 are connected with each other, the heat conducting strip 104 generates heat, so that the temperature detected by the temperature sensing element 106 is the heat common to the heat conducting strip 104 and the carrier plate, the heat on the carrier plate 102 cannot be accurately detected, and the shape of the magnetizable heat conducting strip 104 is limited to an incomplete ring structure, so that the temperature detected by the temperature sensing element 106 only corresponds to the temperature of the carrier plate 102, thereby reducing the influence of self-heating of the heat conducting strip 104.

As shown in fig. 1, for electromagnetic heating, the area where the heating value of the pot is optimal is usually within the diameter D of the outer ring of the coil, so that 1/6 of the diameter D is defined as the inner ring of the temperature measuring area, 5/6 of the diameter D is defined as the outer ring of the temperature measuring area, and the heat conducting fins are distributed in the annular area 110 between the inner ring and the outer ring.

In this embodiment, as shown in fig. 6, the distribution characteristics of the heat conductive sheet are as follows: the center of the minimum thermometric circle 112 with the diameter of 30mm can intersect with the vertical projection of the thermally conductive sheet structure on the panel at any point in the annular region 110. Based on the above, the heat conductive sheet may be distributed as in fig. 2 and 3.

In a specific embodiment, the diameter of the smallest thermometric circle may be selected between 1mm and 80mm, for example, 30mm.

The thickness of the heat conductive sheet may be selected from 0.01mm to 100mm, and may be different for different materials, but is within the range. The position of the minimum temperature measuring circle is limited, the circle center of any position is located in the annular area, meanwhile, the circle center of the minimum temperature measuring circle is intersected with the projection of the heat conducting fin on the bearing plate, and the heat conducting fin is mainly made of a material with the heat transfer rate being greater than that of the supporting plate. For example: when the supporting plate is a microcrystal plate or toughened glass, metal materials such as aluminum, iron, ag and the like can be selected. The heat conducting fin can also be in other three-dimensional shapes, but the vertical projection of the heat conducting fin on the panel can always intersect with the minimum temperature measuring circle (the center of the minimum temperature measuring circle is in the temperature measuring annular area S). When the wire coil is square, the maximum circumcircle of the square wire coil is taken as the diameter D of the outer ring. The outermost end of the heat conducting fin can exceed the outer ring of the coil, or can not exceed the outer ring of the coil, the innermost end of the heat conducting fin can also extend to the central position to assist the central temperature sensor in measuring the temperature, and the diameter of a size limit circle of the heat conducting fin in the temperature sensor measuring device is 2D (D is the size of the coil), and the heat conducting fin is distributed in the size limit circle).

By limiting the shape of the heating coil 202 and the shape of the heat conducting fin 104, heat generated by cooking appliances such as cookware and the like can be effectively transferred by the heat conducting fin 104 when the heating coil 202 heats, and then the temperature sensing piece 106 can sense in time, so that the subsequent processing is facilitated. Specifically, on the carrier plate 102, the projection of the heating coil 202 is larger, which covers the projection of the heat conducting sheet 104, or the projection of the heat conducting sheet 104 is larger, which covers the projection of the heating coil 202, but no matter how the specific positional relationship between the heat conducting sheet 104 and the heating coil 202 is, there is an overlapping portion, and the overlapping portion is located in the annular region, so that the efficient heating power of the heating coil 202 can be fully utilized for cooking.

In one embodiment, the heating coil 202 is annular and the thermally conductive sheet 104 is annular.

In another embodiment, the heating coil 202 is annular and the thermally conductive sheet 104 is circular.

For the heat conducting strip 104, the plurality of heat conducting areas 1044 are formed, the plurality of heat conducting areas 1044 are circumferentially arranged, and the annular areas can be fully filled, so that after heat generated by the heating coil 202 is transferred to the cooking utensil, the situation of abnormal heating in which area can be rapidly and accurately judged through detection of the heat conducting areas 1044 at different circumferential positions, and normal cooking is ensured through timely processing.

It should be added that, a detection position 1046 is provided in each heat conducting area 1044, and a heat conducting strip 1042 extending to the periphery is provided at the detection position 1046, so that when abnormal heat generation exists at any position in the heat conducting areas 1044, heat can be transferred to the detection position 1046 through the heat conducting strip 1042, and temperature detection is completed.

It can be appreciated that the shape of the heat conducting strip 1042 can be radial dispersion shape or petal dispersion shape, so long as the function of measuring temperature in different areas can be realized.

The plurality of heat conduction areas 1044 are limited, and the plurality of heat conduction areas 1044 are limited to be arranged in a circumferential array, namely are uniformly arranged at intervals along the circumferential direction, so that the heating and heat conduction of most cooking appliances are more satisfied, and the temperature measurement effect is improved.

In an aspect, in a case where the heat conductive sheet 104 cannot be magnetized by the heating coil 202, the plurality of heat conductive areas 1044 may be connected to each other so as to form a whole, and it may be defined that some two heat conductive areas 1044 are not connected to each other, and an opening exists.

In another aspect, in the case where the heat conductive sheet 104 may be magnetized by the heating coil 202, at least two heat conductive sections among the plurality of heat conductive areas 1044 are not connected.

By limiting the material of the heat conducting strip 104 and the carrier plate 102, the material of the heat conducting strip 104 is limited to conduct heat more easily, that is, the heat transfer rate of the material of the heat conducting strip 104 is greater than that of the material of the carrier plate 102, so that heat on the carrier plate 102 can be conducted preferentially through the heat conducting strip 104, and therefore, the Wen Ganjian 106 can detect the temperature through the detection position 1046 on the heat conducting strip 104, and the detection speed of the temperature on the carrier plate 102 is improved.
