DETAILED DESCRIPTION

[0021] It should be understood that the terms used herein, the specific structures and functional details disclosed are only for describing specific embodiments and are representative. However, the present invention can be implemented in many alternative forms and should not be construed as being limited to only the embodiments described herein.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and optional embodiments.

[0023] like Figures 1 to 3 As shown, as one embodiment of the present invention, a fanless electric ceramic stove is disclosed, comprising a base 1 and a heating plate 2. The base 1 is provided with a circuit board 11 for controlling the fanless electric ceramic stove. The heating plate 2 is provided with a heating core 21 for heating. The heating core 21 is electrically connected to the circuit board 11. The heating plate 2 is mounted on the base 1 via a connector 3. The heating plate 2 is separated from the base 1 so that the heating plate 2 and the base 1 do not contact each other.

[0024] The biggest source of noise in ceramic stoves is the fan used for heat dissipation. The fanless stove of the present invention does not include a fan, significantly reducing noise and achieving a silent effect. Furthermore, to ensure that excessive temperatures during use without a cooling fan do not damage components such as the circuit board 11 within the stove, the fanless stove of the present invention separates the heating plate 2 from the base 1, connecting them only via a connector 3. This eliminates contact between the heating plate 2 and the base 1. This significantly reduces the amount of heat transferred from the heating plate 2 to the base 1, preventing damage to components such as the circuit board 11 due to high temperatures. This reduces noise while also improving the stove's heat resistance and ensuring that high temperatures do not easily affect internal components.

[0025] Optionally, a recessed cavity 14 is formed on the base 1, and the bottom of the heating plate 2 at least partially extends into the cavity 14; an air passage 141 is formed between the bottom of the heating plate 2 and the cavity 14 to prevent the heating plate 2 from contacting the base 1. In this embodiment, a cavity 14 is formed on the base 1, and the bottom of the heating plate 2 at least partially extends into the cavity 14. While ensuring that the base 1 and the heating plate 2 do not contact each other, the overall volume of the electric ceramic stove is reduced, which is conducive to miniaturization. The air passage 141 is formed between the bottom of the heating plate 2 and the cavity 14, and the heat from the heating plate in the cavity 14 can be discharged through the air passage 141, ensuring that the temperature in the cavity 14 does not become too high, thereby preventing high temperature from damaging the components of the circuit board 11 in the base 1.

[0026] Optionally, a pressure sensor is provided on the connector 3; when the pressure sensor detects that a heating object is placed on the heating plate 2, the circuit board 11 controls the heating core 21 to heat. In this embodiment, the pressure sensor is provided on the connector 3. When a heating object such as a pot or kettle is placed on the heating plate 2, the pressure sensor detects the pressure change, and the circuit board 11 controls the heating core 21 to heat, making the operation of the electric ceramic stove more intelligent and convenient.

[0027] Optionally, a first mounting cavity 211 is provided on the heating core 21, a heating coil is installed in the first mounting cavity 211, and the heating coil is electrically connected to the circuit board 11. In this solution, the heating coil is installed in the first mounting cavity 211 to achieve heating of the heating plate 2 with a small volume.

[0028] Optionally, the heating plate 2 includes a bottom shell 22, in which a second mounting cavity 221 is defined. The heating core 21 is installed in the second mounting cavity 221, with the bottom of the heating core 21 suspended in the air. A connecting hole 212 is defined at the bottom of the first mounting cavity 211, connecting the first mounting cavity 211 with the second mounting cavity 221. In this embodiment, the connecting hole 212 is defined at the bottom of the first mounting cavity 211. Firstly, the heat within the first mounting cavity 211 can be transferred to the second mounting cavity 221 through the connecting hole 212, and preferably then transferred to the outside through the bottom shell 22 for heat dissipation, thereby accelerating heat dissipation. Secondly, the internal air pressure of the first mounting cavity 211 can be balanced, ensuring that the heating plate 2 is not easily damaged.

[0029] Specifically, the heating plate 2 includes a middle frame 23 and an upper cover 24. The middle frame 23 has an opening 231, the bottom shell 22 is connected to the middle frame 23, and the first mounting cavity 211 is aligned with the opening 231. The upper cover 24 is mounted on the middle frame 23, and the connector 3 is mounted on the middle frame 23. During use, heat from the heating core 21 is transferred to the upper cover 24, and a heating object such as a stove or teapot is placed on the upper cover 24 for heating.

[0030] Regarding the specific connection method between the base 1 and the heating plate 2, in one embodiment, the base 1 has a mounting slot 131 corresponding to the connecting post; the connecting post is inserted into the mounting slot 131 to secure the connection and cannot be removed at any time. Specifically, the connecting post and the mounting slot 131 can be fixed together using glue or screws. The connection method of inserting the connecting post into the mounting slot 131 can make the heating plate 2 more secure. In this case, the wiring in the base 1 can pass through the connecting post into the heating plate 2 to achieve electrical connection with the heating core 21. In another embodiment, the connecting member 3 is connected to the heating plate 2, specifically, the connecting member 3 is provided on the middle frame 23. The base 1 has a mounting slot 131, and the connecting post is inserted into the mounting slot 131 to connect the connection detachably. That is, the heating plate 2 can be removed from the mounting slot 131 at any time, which facilitates storage and cleaning of the interior of the electric ceramic hob, and facilitates repair or replacement if the base 1 or heating plate 2 is damaged. In this embodiment, specifically, a first electrical contact point is provided at the end of the connecting member 3, and the first electrical contact point is electrically connected to the heating core 21; a mounting groove 131 is provided on the base 1, and a second electrical contact point is provided in the mounting groove 131, and the second electrical contact point is electrically connected to the circuit board 11; the connecting member 3 can be detachably inserted into the mounting groove 131, and the first electrical contact point is electrically connected to the second electrical contact point.

[0031] Optionally, the spacing of the air passages 141 is 5 to 18 mm, ensuring a compact ceramic stove while providing good heat dissipation. Optionally, an air inlet 121 is provided in the cavity 14. The provision of the air inlet 121 can further enhance air circulation in the cavity 14 and improve heat dissipation.

[0032] Optionally, the sidewalls of the cavity 14 are tilted so that the cavity 14 is larger at the top and smaller at the bottom, which is beneficial for the hot air in the cavity 14 to flow to the outside and enhance the heat dissipation effect.

[0033] Optionally, the sidewalls of cavity 14 are provided with ridges extending from the bottom of cavity 14 toward opening 231 of cavity 14. In this embodiment, the ridges extending from the bottom toward opening 231 on the sidewalls of cavity 14 facilitate orderly circulation of hot air from cavity 14 to the outside, improving heat dissipation efficiency. This also increases the surface area of ​​cavity 14. When absorbing the same amount of heat, the temperature rise of base 1 is smaller, which helps protect components such as circuit board 11 within base 1.

[0034] Optionally, the bottom of the side wall of the cavity 14 is folded outward to form a vertical wall 142. In this embodiment, the bottom of the side wall of the cavity 14 is folded outward to form the vertical wall 142, so that the air entering from the air inlet 121 forms a certain convection effect with the heated air above at the position of the vertical wall 142, accelerating the mixing of the newly entered air with the original hot air in the cavity 14, ensuring a uniform temperature in the cavity 14, and preventing local excessive temperature.

[0035] Optionally, the base 1 includes a base plate 12 and a main base shell 13. The base plate 12 is positioned over the bottom of the main base shell 13. The main base shell 13 and the base plate 12 together define an inner cavity 15 and a concave cavity 14. The inner cavity 15 surrounds and isolates the concave cavity 14. Components such as the circuit board 11 are mounted in the inner cavity 15, further preventing heat transfer to and damage to the circuit board 11 and other components. An air inlet 121 is provided on the base plate 12. A mounting slot 131 is provided on the main base shell 13.

[0036] The above is a further detailed description of the present invention in conjunction with specific optional embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
