Referring to fig. 2, in order to reduce the size of the temperature measuring circuit board 10, the temperature measuring assembly in the cooking device includes the temperature measuring circuit board 10 and a plurality of temperature measuring elements 20, wherein a first end of each temperature measuring element 20 is electrically connected with the temperature measuring circuit board 10 through a common trace 30, a second end of each temperature measuring element 20 is electrically connected with the temperature measuring circuit board 10 through a third trace 40, and one end of the third trace 40, which is close to the second end of the temperature measuring element 20, is located inside an area surrounded by the temperature measuring elements 20, and the common trace 30 is located at an edge of the area surrounded by the temperature measuring elements 20.

When the temperature of the common wire 30 and the third wire 40 is higher than the temperature of the panel, the temperature measured by the temperature measuring element 20 is the temperature of the common wire 30 and the third wire 40, that is, the temperature received by the temperature measuring circuit board 10 is higher than the actual temperature of the panel, which is easy to cause the incorrect start of the dry-heating preventing function of the cooking device, and the cooking device cannot be used normally. And the service lives of the common wire 30 and the third wire 40 are affected by the large heat generated by the common wire 30 and the third wire 40, and the common wire 30 and the third wire 40 are damaged and broken easily, so that the installation stability of the temperature measuring assembly is poor.

Referring to fig. 3 to 12, the cooker provided in the present application includes a bottom case 100, a panel 200, a temperature measuring assembly 300 and a heating element 400, wherein the panel 200 is covered on the bottom case 100 and encloses a containing cavity 500 with the bottom case 100, and the temperature measuring assembly 300 and the heating element 400 are both located in the containing cavity 500. The temperature measuring assembly 300 includes a temperature measuring circuit board 310 and a plurality of temperature measuring elements 320, wherein the plurality of temperature measuring elements 320 are disposed on the temperature measuring circuit board 310 at intervals.

The temperature measuring circuit board 310 is provided with a wire 330, the temperature measuring element 320 comprises a first pole 321 and a second pole 322, the wire 330 connected with the same temperature measuring element 320 comprises a first wire 331 and a second wire 332, the first wire 331 is connected with the first pole 321, the second wire 332 is connected with the second pole 322, and the first wire 331 and the second wire 332 are all in non-annular arrangement.

Wherein the panel 200 may be a high boron silicon panel.

It should be noted that the first wires 331 and the second wires 332 may be located in an area surrounded by the plurality of temperature measuring elements 320, or the first wires 331 and the second wires 332 may be partially located outside an area surrounded by the plurality of temperature measuring elements 320, which is not particularly limited herein.

Specifically, referring to fig. 11 and 12, the temperature measuring circuit board 310 is provided with a trace 330, the temperature measuring element 320 includes a first pole 321 and a second pole 322, the trace 330 connected to the same temperature measuring element 320 includes a first trace 331 and a second trace 332, the first trace 331 is connected to the first pole 321, and the second trace 332 is connected to the second pole 322 without setting a common trace. Because the first wire 331 and the second wire 332 are all non-annular, when the heating element 400 works, the magnetic lines of force of the heating element 400 cut the first wire 331 and the second wire 332, the heat generated by the first wire 331 and the second wire 332 is smaller, the temperature measured by the temperature measuring element 320 is the temperature of the panel 200, and the temperature measuring accuracy is higher. The heat that first line 331 and second line 332 produced is less, can improve the life-span of first line 331 and second line 332, and first line 331 and second line 332 are not fragile fracture, and the installation stability of temperature measurement subassembly 300 is better.

In some embodiments, referring to fig. 11 and 12, the first trace 331 and the second trace 332 near the temperature measurement element 320 are both located within an area surrounded by a plurality of temperature measurement elements 320.

Specifically, the polarities of the first pole 321 and the second pole 322 are opposite.

It can be understood that when the magnetic lines of force of the heating element 400 cut the first trace 331 and the second trace 332, the area enclosed by the first trace 331 and the second trace 332 connected to the same temperature measuring element 320 affects the heat generated by the first trace 331 and the second trace 332. Therefore, the first wires 331 and the second wires 332 close to the temperature measuring elements 320 are located in the area surrounded by the plurality of temperature measuring elements 320, which is beneficial to reducing the area surrounded by the first wires 331 and the second wires 332, thereby reducing the heat generation and improving the temperature measuring accuracy of the corresponding temperature measuring elements 320. Moreover, the first trace 331 and the second trace 332 that are close to the temperature measuring element 320 are both located in an area surrounded by the plurality of temperature measuring elements 320, which is beneficial to reducing the size of the temperature measuring circuit board 310.

In some embodiments, the first pole 321 and the second pole 322 are respectively located on two opposite sides of the temperature measuring element 320, and the first trace 331 and the second trace 332 near one side of the temperature measuring element 320 are respectively connected to two opposite sides of the temperature measuring element 320. The first wires 331 and the second wires 332 connected to the same temperature measuring element 320 are parallel to each other and are spaced apart from each other between the temperature measuring circuit board 310 and the temperature measuring element 320. In this way, the wiring arrangement of the first wires 331 and the second wires 332 is facilitated, the signal interference of the first wires 331 and the second wires 332 is reduced, and the area enclosed by the first wires 331 and the second wires 332 is further reduced.

Specifically, referring to fig. 11 and 12, the first trace 331 and the second trace 332 connected to the same temperature measuring element 320 are disposed in parallel and spaced apart from each other from a side far from the temperature measuring element 320 to a position close to the temperature measuring element 320.

In one possible implementation, the routing path of the routing 330 includes a plurality of straight sections 333, and an included angle a between two adjacent straight sections 333 is an obtuse angle.

Illustratively, the routing path of the routing 330 may include one straight segment 333, two straight segments 333, or a plurality of straight segments 333.

It can be appreciated that the included angle a between two adjacent straight sections 333 is an obtuse angle, which is convenient for manufacturing the trace 330 and transmitting signals.

Specifically, the included angle a between two adjacent straight line segments 333 is not smaller than 135 °.

It can be appreciated that when the included angle a between two adjacent straight-line segments 333 is smaller than 135 °, the signal transmission in the wire 330 is not facilitated, and the processing of the wire 330 is not facilitated.

Specifically, the width b of the first trace 331 and the width c of the second trace 332 are both 0.15-1mm.

When the width b of the first trace 331 and the width c of the second trace 332 are smaller than 0.15mm, the first trace 331 and the second trace 332 are not easy to process, have low reliability, and are easy to be damaged by heating by the heating member 400.

When the width b of the first trace 331 and the width c of the second trace 332 are greater than 1mm, the magnetic lines of force of the heating element 400 cut the first trace 331 and the second trace 332 when the heating element 400 works, and the heat generated by the first trace 331 and the second trace 332 is relatively large, so that the installation stability and the temperature measurement accuracy of the temperature measuring component 300 are affected.

In one possible implementation, the spacing e between the first trace 331 and the second trace 332 connected to the same temperature sensing element 320 is 0.2-1mm.

When the distance e between the first wire 331 and the second wire 332 connected to the same temperature measuring element 320 is smaller than 0.2mm, the first wire 331 and the second wire 332 are not easy to process and signal interference is easy to occur.

When the distance e between the first wire 331 and the second wire 332 connected to the same temperature measuring element 320 is greater than 1mm, the area enclosed by the first wire 331 and the second wire 332 is larger, which is easy to affect the installation stability and the temperature measuring accuracy of the corresponding temperature measuring assembly 300.

In one possible implementation, the area surrounded by the plurality of temperature measuring elements 320 is a circular area, and at least a part of the temperature measuring elements 320 are distributed at intervals along the circumference of the circular area, and the center of the orthographic projection of the heating element 400 on the plane of the temperature measuring circuit board 310 coincides with the center of the circular area.

Because the temperature of the panel 200 corresponding to the center of the heating element 400 is higher, the center of the orthographic projection of the heating element 400 on the plane of the temperature measuring circuit board 310 coincides with the center of the circular area, so that the accuracy of temperature detection of the panel 200 by the temperature measuring assembly 300 can be improved, and damage to the panel 200 and the cookware caused by the too high heating temperature of the heating element 400 can be effectively avoided.

Illustratively, the heating element 400 may be circular or rectangular.

In one possible implementation, the plurality of temperature sensing elements 320 includes a first temperature sensing element 323 and a plurality of second temperature sensing elements 324, the plurality of second temperature sensing elements 324 enclosing a circular area, the first temperature sensing element 323 being located within the circular area.

It can be appreciated that by providing the first temperature measuring element 323 and the plurality of second temperature measuring elements 324 to measure the temperature of the plurality of positions of the panel 200, the accuracy of the temperature control of the panel 200 can be improved.

In one possible implementation, the first temperature measuring element 323 is one, and the first temperature measuring element 323 is located at the center of the circular area.

Thus, the number of the first temperature measuring elements 323 is one, the number of the first temperature measuring elements 323 is small, and the production cost of the cooking device can be reduced.

In another possible implementation, the first temperature measuring elements 323 are plural, wherein one first temperature measuring element 323 is located at the center of the circular area, and the rest of the first temperature measuring elements 323 are distributed at intervals along the radial direction of the circular area.

In this way, the number of the first temperature measuring elements 323 is larger, the measuring points are larger, and the accuracy of temperature control of the panel 200 can be improved.

In some embodiments, the orthographic projection of the second temperature sensing element 324 on the plane of the heating element 400 is near the midpoint of the radius of the heating element 400.
