Description

Technical Field

[0001] The invention relates to an electric heating dock, in particular to a three-dimensional heat transfer electric heating dock for cooking. Background Art

[0002] Various electric heating cooking utensils, such as electric rice cookers that mainly realize steaming and cooking functions, electric baking pans that are mainly used for baking, microwave ovens that are mainly used for various rapid heating functions, as well as electric frying pans and induction cookers, use electric current for heating. They have the advantages of convenience, speed, multi-purpose, safety and environmental protection. They are cooking utensils that combine modern science and technology with traditional folk customs and are widely used in people's daily lives. 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, in the process of use, induction cookers have problems such as high failure rate, high power consumption, electromagnetic radiation, and flat bottom that is not conducive to stir-frying. Compared with induction cookers, electric frying pans have low failure rate, 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, this heating method mostly uses the flat surface of the pot bottom for heating, which is obviously different from the traditional open flame three-dimensional heating method. In addition, the solution of fixing the heating plate on the bottom of the pot is not convenient for cleaning, disassembly and maintenance, and cooking skills such as flipping and frying cannot be achieved, so its applicability and practicality are limited. Therefore, it is necessary to design an electric heating cooking device with a separate pot and stove, simulated open flame three-dimensional heating, easy to clean, and more able to meet the needs of traditional Chinese cooking skills. Summary of the invention

[0003] In view of the shortcomings of current electric heating cooking devices, the present invention proposes a three-dimensional heat transfer electric heating dock which has a simple structure, is easy to clean, has a separate pot and stove, a replaceable pot body, simulates open flame cooking, and can better meet the needs of traditional Chinese cooking skills.

[0004] The technical solution to achieve the above object is: an electric heating dock, comprising a base, a supporting mechanism and an automatic power on / off mechanism arranged in a cavity of the base, a heating mechanism installed on the supporting mechanism, a spherical pot body placed on the heating mechanism, and a current regulator arranged outside the base shell;

[0005] The support mechanism comprises a heating tube bracket II and a heating tube bracket I, the heating tube bracket I is provided with a support claw, a ball joint is provided at the tip of the support claw, and a tail bracket is installed above the ball joint; an adjustment spring is provided above the heating tube bracket I, the heating tube bracket II is connected to the upper end of the adjustment spring, a support ring is provided on the heating tube bracket II, and a support sleeve is installed on the support ring;

[0006] There are three tail brackets and three supporting claws, and the three supporting claws are evenly distributed on the outer cylindrical surface of the heating tube bracket 1 at an interval of 120°. The heating tube bracket 1 is supported on the base by means of a supporting spring; the three tail brackets are evenly distributed at an interval of 120°.

[0007] The heating mechanism comprises three groups of heating tubes and three groups of heat conducting plates, the heat conducting plates are supported by the tail bracket, and the heating tubes are installed in the grooves of the heat conducting plates;

[0008] The heating tube is formed by bending a single heating tube, the angle between the two bending edges in the horizontal plane is 60°, and the single bending edge is arc-shaped and adapted to the shape of the spherical pot body;

[0009] Each group of heat conducting sheets includes two branches, and the three groups of heat conducting sheets have a total of 6 branches. The angle between the two branches is 60°. The upper surface of each branch is a slender strip spherical surface. The 6 branches of the heat conducting sheets are arranged radially and fit the bottom surface of the spherical pot body.

[0010] The support ring is provided with three spherical protrusions spaced 120° apart and matched with the annular groove in the support sleeve. The installation clearance between the support ring and the support sleeve is 2mm to 3mm to ensure a moderate amount of movement.

[0011] The automatic power on / off mechanism comprises a ceramic support, a ceramic tentacle, a passive elastic copper sheet, a ceramic ring and an active elastic copper sheet are sequentially arranged on the ceramic support, the ceramic tentacle is arranged on the outer side of the heating tube bracket 1, and one end of the passive elastic copper sheet and the active elastic copper sheet are respectively connected to three groups of heating tubes connected in series and a current regulator through wires;

[0012] The inner wall of the base (1) is provided with a heat insulation coating.

[0013] The present invention simulates the characteristics of flame heating, and simulates open flame heating by means of the radial arrangement of heat conductive plates that fit the spherical pot body, thereby fitting the overall heat transfer in space. The closer to the center of the pot bottom, the denser the arrangement of the heat conductive plates, and the higher the temperature during the heating process. The farther from the center of the pot bottom, the looser the arrangement of the heat conductive plates, and the temperature gradually decreases. This scheme is closer to actual open flame heating.

[0014] The upper surface of the heat conductive sheet adopted in the present invention is a slender spherical 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 conductive sheet and the spherical pot body. The heat conductive sheet is in the shape of a slender strip, which effectively reduces the width of the contact heat transfer surface between the heat conductive sheet and the spherical pot body, making the heat transfer surface closer to an arc line, and has strong adaptability to the shape of the pot body. When the size of the pot body changes within a certain range, effective fitting and heat transfer can still be guaranteed.

[0015] The present invention adopts adaptive floating adjustment and anti-overturning technology, and uses the set ball joint, adjustment spring and the reserved gap between the support ring and the support sleeve to adjust the position of the center of the slender strip spherical surface of the heat conductive plate and the spherical pot body, thereby adjusting the fit between the spherical pot body randomly placed in the heating mechanism and the heat conductive plate; the support ring is used to limit the activity of the heat conductive plate to prevent the heat conductive plate from overturning during use.

[0016] When the electric heating dock is working, the spherical pot body is placed on the heating mechanism, and the supporting spring is compressed by the dead weight of the spherical pot body. The ceramic tentacles press down the active elastic copper sheet, and the spherical contacts on the active elastic copper sheet contact the passive elastic copper sheet to connect the power supply. The heating tube of the heating mechanism is energized and heated, and the heat generated by the heating tube is transferred by the heat conductive sheet to the spherical pot body that fits tightly with the heat conductive sheet to complete the heating and cooking of the food in the pot. During the cooking process, the current regulator adjusts the working current and then adjusts the heating power of the heating tube. When the spherical pot body is moved away from the heating mechanism during the cooking process, under the action of the restoring force of the supporting spring, the ceramic tentacles move up to separate the spherical contacts on the active elastic copper sheet from the passive elastic copper sheet, thereby achieving instant power off.

[0017] The present invention adopts spatial stereoscopic heating technology. Compared with the existing plane heating technology in which the heating tube is fixed to the bottom of the pot, the heating surface is larger and the temperature field in the pot is closer to that of open flame heating.

[0018] 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.

[0019] The present invention adopts the pot-stove separation technology, the pot body and the heating mechanism are separated, the pot body can be taken away from the heating mechanism at will, it is more convenient to use traditional Chinese cooking techniques such as stir-frying, and the cooking process is also closer to traditional Chinese open fire cooking; the pot-stove separation also effectively avoids the cleaning water entering the heating mechanism during the cleaning process to corrode the heating mechanism and cause a short circuit in the control circuit, the cleaning is more convenient, and the instant on and off makes the use safer.

[0033] The support sleeve (9) is installed correspondingly to the ball joint (4), and the horizontal line connecting the center of the spherical protrusion of the corresponding support ring (8) and the center of the ball joint (4) passes through the center of the support ring (8);
