[0002] An oven is a device that uses hot air to bake and cook food; it is generally a closed or semi-closed structure.

[0003] Among them, the microcrystalline glass oven is one of the more novel ovens. It uses a graphene coating on the surface of the microcrystalline glass to release far-infrared rays by passing electricity through the graphene, so that food can be baked.

[0004] The shortcomings of existing microcrystalline glass ovens are that microcrystalline glass has limited heat resistance, and continuous energization of graphene will cause the temperature of microcrystalline glass to rise continuously, resulting in overheating and damage. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a heating plate and oven with precise temperature control that uses an elastic element to stably press a temperature sensor onto a microcrystalline glass surface for real-time temperature monitoring.

[0020] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model should all be considered within the scope of protection claimed by this utility model.

[0021] Example 1: like Figures 1-5As shown, this utility model discloses a heating plate with precise temperature control, comprising: The base 1 includes a base plate 11; Microcrystalline glass 2 is disposed on the base 1 and located above the base plate 11. Graphene coating 21 is disposed on the microcrystalline glass 2. Temperature sensor 3, the temperature measuring part of temperature sensor 3 is attached to the lower surface of microcrystalline glass 2; Elastic element 4 is used to press the temperature sensor 3 upward onto the microcrystalline glass 2; The control center, temperature sensor 3, and graphene coating 21 are all electrically connected to the control center.

[0022] Therefore, 1. By energizing the graphene coating 21 to release far-infrared rays of 8-15μm, since the far-infrared wavelength is similar to that of meat radiation, a better heating effect is achieved, and it can be absorbed by the deep tissues of the meat; 2. Under the elastic restoring force of the elastic element 4, the temperature sensor 3 is effectively pressed to the bottom of the microcrystalline glass 2, enabling the temperature sensor 3 to monitor the temperature of the microcrystalline glass 2 in real time. Thus, when the graphene coating 21 heats up and the microcrystalline glass 2 reaches the preset maximum temperature, the temperature sensor 3 can send a signal to the control center, which then controls the power supply to the graphene coating 21 to cut off the heating, thereby stopping the graphene coating 21 from heating up and preventing the microcrystalline glass 2 from overheating and being damaged. After the microcrystalline glass 2 cools down and falls below the preset maximum temperature, the temperature sensor 3 can send a signal to the control center, which then controls the power supply to the graphene coating 21 to resume heating. This reciprocating control keeps the temperature of the heating plate basically stable at the preset maximum temperature, making the heating more stable.

[0023] Preferably, the graphene coating 21 is disposed on the lower surface of the microcrystalline glass 2.

[0024] Specifically, the elastic element 4 is a compression spring.

[0025] In addition, the temperature sensor 3 in this embodiment is provided with a downwardly extending guide post 31, and the base plate 11 is provided with a through hole 121. The guide post 31 passes through the through hole 121 downwardly, and the elastic member 4 is sleeved on the outer periphery of the guide post 31. The upper end of the elastic member 4 abuts against the temperature sensor 3 and the lower end abuts against the base plate 11.

[0026] Therefore, the cooperation between the guide post 31 and the transmission hole enables the temperature sensor 3 to float vertically, and the temperature sensor 3 is pressed more stably to the bottom of the microcrystalline glass 2 under the stable state of the elastic element 4 sleeved on the guide post 31.

[0027] In addition, the base plate 11 in this embodiment is provided with an assembly hole 111, which allows the temperature sensor 3 and the elastic element 4 to pass through from below the base plate 11 to above the base plate 11; correspondingly, the base plate 11 includes a spring pressure plate 12, with a through hole 121 provided on the spring pressure plate 12. The spring pressure plate 12 is detachably provided below the base plate 11 by means of bolts and nuts, and covers the assembly hole 111; the lower end of the elastic element 4 abuts against the spring pressure plate 12.

[0028] Therefore, with the spring pressure plate 12 disassembled, the temperature sensor 3 and the elastic element 4 are assembled with the assembly hole 111 facing upwards. After assembly, the spring pressure plate 12 supports the elastic element 4 while the assembly hole 111 is sealed, making assembly more convenient.

[0029] In addition, the base plate 11 includes two fittings 13, which are disposed at both ends of the base plate 11. Each fitting 13 is provided with an assembly slot 131, and each assembly slot 131 is provided with an assembly opening 132. The two assembly openings 132 are arranged opposite to each other, and the two ends of the microcrystalline glass 2 are respectively inserted into the assembly openings 132.

[0030] Preferably, the assembly 13 is a metal part, and the assembly 13 is formed by bending, which makes the processing more convenient. The assembly 13 and the base plate 11 are detachably connected by bolts and nuts.

[0031] Furthermore, heat insulation sleeves 5 are respectively fitted at both ends of the microcrystalline glass 2. Each heat insulation sleeve 5 includes a heat-insulating top 51, a heat-insulating side 52, and a heat-insulating bottom 53. The heat-insulating top 51 separates the microcrystalline glass 2 from the upper surface of the mounting slot 131; the heat-insulating side 52 separates the surface of the microcrystalline glass 2 and the mounting slot 131 away from the mounting opening 132; and the heat-insulating bottom 53 separates the microcrystalline glass 2 from the lower surface of the mounting slot 131. This design of the heat insulation sleeves 5 reduces heat loss caused by the microcrystalline glass 2 transferring heat to the mounting slot 13 via thermal conduction.

[0032] Preferably, the upper surface of the base plate 11 is covered with a thermal insulation layer, which reduces heat loss.

[0033] Specifically, temperature sensor 3 uses PT1000.

[0034] Example 2: An oven, comprising a heating plate with precise temperature control as described in Embodiment 1.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
