Description
Technical field
The present invention relates to a kind of electromagnetic heating technique, especially a kind of coil disk structure of electromagnetic induction heating.
Background technique
Electromagnetic heating has begun a large amount of uses, leaks electricity in order to prevent, is heated to be isolation heating cookware, and cookware becomes very
Safety, but become difficult but also detecting temperature in control, it is usually all to be carried out across very thick insulator (such as micro-crystal plate)
Measurement indirectly, while being influenced again by coil panel magnetic field, temperature detection error is very big, is usually arranged at the center of coil panel
One temperature sensor, and the magnetic line of force of coil panel is strongest in central area, so error further increases (such as Fig. 1),
Temperature detection inaccuracy causes to control failure and damage, and is not damaged by pressure by cookware stress to solve temperature sensor, meeting in design
Cookware bottom is not contacted with micro-crystal plate, thus can not can correctly detect the true temperature of cookware completely, culinary art effect is deteriorated,
Failure rate is also high.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides the coil disk structure that a kind of failure rate is low, temperature measurement accuracy is high.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of coil disk structure that temperature measurement accuracy is high, including coil panel seat and the coil card slot that is arranged on the coil panel seat,
It is provided with temperature sensor bracket on the coil panel seat, is provided with temperature sensor on the temperature sensor bracket, with institute
The center for stating coil panel seat is the center of circle, using 0.2 times of radius of the coil panel seat as inner circle radius, with the coil panel seat
0.8 times of radius is that exradius is a circle ring area, and the temperature sensor is located in the circle ring area.
The coil card slot includes the spaced multistage coil card slot of circumferential direction along the coil panel seat.
The multistage coil card slot is arranged in a straight line in the radial direction along the coil panel seat, and the temperature sensor is located at
Between the coil card slot of two column radial directions arrangement.
Fixation hole is provided at the outer ledge of the coil panel seat.
The beneficial effects of the present invention are: coil disk structure of the invention is by being arranged temperature sensor in coil panel seat
0.2 times of radius solves the problems, such as that the magnetic line of force is intensive at center, while also solving cookware to the region between 0.8 times of radius
The problem of not reaching bottom substantially increases the precision of control temperature, reduces the failure rate of equipment operation.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is coil disk structure schematic diagram in the prior art；
Fig. 2 is structural schematic diagram of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
In the description of the present invention, it is to be understood that, term " on ", "lower", "front", "rear", "left", "right", "top",
