Description

Technical Field

[0001] The invention relates to an electric heating cooking device, in particular to a pot and stove separated electric heating cooking device. Background Art

[0002] Electric heating cooking utensils use electric current for heating. They are convenient, fast, multi-purpose, safe and environmentally friendly. They are cooking utensils that combine modern science and technology with traditional folk customs. Therefore, various electric heating cooking utensils such as rice cookers, electric frying pans, electric baking pans, induction cookers, microwave ovens, etc. are widely used in people's daily lives. Among them, rice cookers mainly realize the steaming function, electric baking pans mainly realize the baking function, and microwave ovens are mainly used for various rapid heating. Induction cookers are a commonly used frying and cooking heating device with the advantages of fast heating, high thermal efficiency, and separation of pots and stoves. However, during use, induction cookers have high failure rates, high power consumption, electromagnetic radiation, and flat bottoms that are not conducive to stir-frying, which also trouble people from time to time. Compared with induction cookers, electric frying pans have low failure rates, low power consumption, and no need to worry about electromagnetic radiation. However, the existing electric frying pan fixes the heating plate on the pot body. The characteristics of this heating device are that the electric frying pan has a simple structure and heats up quickly. Although it can meet the cooking needs of frying to a certain extent, it is not convenient to clean, disassemble and repair, and cooking skills such as flipping cannot be realized, so its applicability and practicality are limited. Therefore, it is necessary to design an electric heating cooking device with a separate pot and stove, which is easy to clean and can better meet the needs of traditional Chinese cooking skills. Summary of the invention

[0003] Aiming at the shortcomings of current electric heating cooking devices, the present invention proposes an electric heating cooking device which is simple to implement, has a separate pot and stove, is easy to clean, and can better meet the needs of traditional Chinese cooking skills.

[0004] The technical scheme for achieving the above object is: a stove-separated electric heating cooking device, comprising a base, a heating dock, an automatic power-on / off mechanism and a current regulator, wherein the heating dock and the automatic power-on / off mechanism are arranged in the base cavity, the current regulator is arranged outside the base shell, the heating dock is supported on the bottom surface of the base cavity by means of a supporting spring, the supporting spring is sleeved on a spring guide and a limit bolt, and the upper end of the supporting spring is connected to a heating tube bracket;

[0005] The heating dock comprises a heating tube bracket, a heating tube support arm, an elastic fixing claw, an annular heating tube and a scaly heat conducting sheet. The outer cylindrical side of the heating tube bracket is provided with an upwardly inclined heating tube support arm, the elastic fixing claw is provided at the upper end of the heating tube support arm, the annular heating tube is clamped by the elastic fixing claw, and the heat conducting sheet is provided on the annular heating tube for heating the spherical pot body.

[0006] The automatic on-off mechanism comprises a connecting rod, a ceramic tentacle, an active elastic copper sheet, a passive elastic copper sheet, a ceramic insulating support and a ceramic insulating ring, wherein the passive elastic copper sheet is arranged on the ceramic insulating support, the passive elastic copper sheet is connected to the active elastic copper sheet through the ceramic insulating ring, the ceramic tentacle installed at one end of the connecting rod is arranged above the active elastic copper sheet, and the other end of the connecting rod is horizontally fixed on the heating tube bracket;

[0007] One end of the active elastic copper sheet and the passive elastic copper sheet are both provided with a raised spherical contact, and the other ends of the active elastic copper sheet and the passive elastic copper sheet are respectively connected to the current regulator through wires, and the outer surface of the connecting wires is covered with a heat-insulating wire tube;

[0008] The heat conducting sheet can move along the axis of the annular heating tube, and gap adjusting sheets are provided between adjacent heat conducting sheets to adjust the installation gap between the heat conducting sheets to ensure a moderate degree of mobility;

[0009] The fan-shaped angle of the scale-shaped heat conducting sheet in the horizontal plane is 20°, the upper surface of the heat conducting sheet is a spherical concave surface and contacts the spherical pot body, and the curvature of the spherical concave surface of the heat conducting sheet is adapted to the curvature of the spherical pot body to ensure the contact area between the heat conducting sheet and the spherical pot body, which is convenient for heat transfer; the inner wall of the base has a heat insulation coating;

[0010] The heating tube bracket has three supporting arms, and the distance between two adjacent supporting arms is 120 degrees to ensure stable support.

[0011] The present invention adopts the pot-stove separation technology. Compared with the existing technology of fixing the heating tube to the bottom of the pot, the pot body can be taken away from the heating dock at will, which is more convenient for using traditional Chinese cooking techniques such as stir-frying, and the cooking process is also closer to traditional Chinese open fire cooking.

[0012] The present invention adopts the pot-stove separation technology, and the pot body and the heating dock are separated. Compared with the existing technology in which the heating tube is fixed to the bottom of the pot, it avoids the cleaning water from entering the heating device to corrode the heating mechanism and cause a short circuit in the control circuit during the cleaning process. It is safer to use and more convenient to clean.

[0013] The present invention adopts a spherical pot body, and may also adopt other pot bodies with pointed bottoms and curved surfaces. Compared with the existing flat-bottomed pot body, stir-frying is more convenient.

[0014] The upper surface of the scaly heat conducting sheet used in the present invention is a spherical concave surface, and the curvature of the spherical concave surface is adapted to the curvature of the spherical pot body, which is more conducive to the fitting of the heat conducting sheet and the spherical pot body.

[0015] The present invention adopts separate multi-point heat transfer to fit the overall heat transfer, has strong adaptability to the shape of the bottom surface of the pot body, and can realize heat transfer to the bottom of the pot with different shapes; by reducing the fan-shaped angle in the horizontal plane of the heat conducting plate, the contact area between a single heat conducting plate and the pot body can be further reduced, and the number of heat conducting plates can be increased, thereby further improving the fitting accuracy of the heat conducting plate to the bottom surface of the pot body.

[0016] When the pot-stove separated electric heating cooking device is working, the spherical pot body is placed on the heating dock, the spherical concave surface on the heat conductive sheet installed on the annular heating tube of the heating dock fits with the spherical pot body, the supporting spring is compressed under the dead weight of the spherical pot body, the connecting rod drives the ceramic tentacles to press down the active elastic copper sheet, the spherical contact on the active elastic copper sheet contacts with the passive elastic copper sheet to connect the power, the annular heating tube generates heat and transmits the heat to the spherical pot body through the scaly heat conductive sheet to achieve heating and cooking of the food in the pot; during the cooking process, the current regulator adjusts the working current and thus adjusts the heating power of the annular heating tube; when the spherical pot body leaves the heating dock, under the action of the restoring force of the supporting spring, the connecting rod drives the ceramic tentacles to move up, the spherical contact on the active elastic copper sheet separates from the passive elastic copper sheet, and instant power off is achieved.

[0017] The present invention adopts instant on-off technology, and realizes mechanical real-time automatic on-off of the heating power supply by means of the dead weight of the pot body, thereby saving energy. No additional sensors and control circuits are required during operation, and the structure is simpler, the operation is more reliable, and it is more practical. BRIEF DESCRIPTION OF THE DRAWINGS
