Embodiment 1

[0020] Embodiment one, such as figure 1 As shown, the present invention’s energy-saving and rapid electric pan heating method and its electric heating pan are that the bottom 10 of the pot body 1 is coated with aluminum 2, and three or more than three open-loop circular electric heating tubes 3 are arranged inside and outside the bottom 10 of the pan. Multi-circle annular heating, the pot body 1 is heated by placing the vertical pipe 4 to heat the liquid in the pot at intervals of the temperature difference between the inside and outside of the vertical pipe 4, the configuration of the pot body 1: when in use, it can be placed in the middle of the bottom 10 of the pot freely The height of the pick-and-place is less than the vertical depth of the pot body, and the diameter of the inner cavity circle (or inner cavity tangent circle) is equal to or greater than the circular straight vertical tube 4 of the diameter of the second electric heating tube 3 from outside to inside. The ...

Embodiment 2

[0021] Embodiment two, such as figure 2 As shown, the difference between the energy-saving and rapid electric pan heating method and the electric heating pan of the present invention and the first embodiment is that the vertical pipe 4 is a vertical pipe with a thinner, lower, and thicker diameter in the middle. The diameter reduction of the standpipe 4 is gradually excessive diameter reduction. The upper thicker and lower thicker are the thin and small bell mouths of the upward section and the large and thick bell mouths of the downward section respectively. The gradual excessive diameter reduction means that at least the vertical tangent line of the side wall of the diameter reduction area of ​​the standpipe is arc-shaped.

Embodiment 3

[0022] Embodiment three, such as image 3 As shown, the difference between the present invention's energy-saving and rapid electric pan heating method and the electric heating pan thereof is that the top of the pan bottom 10 corresponding to the vertical pipe 4 has a conical annular slope shape with a low inside and a high outside. The hole on the end face of the lower opening of the vertical pipe can be in the shape of a conical ring with a corresponding high inner height and outer lower concave upper face. The diameter of the cavity circle or the tangential circle of the cavity at the bottom of the vertical pipe 4 can also be equal to or greater than the diameter of the first electric heating tube 3 from outside to inside.

Abstract

The invention relates to an energy-saving rapid electric cooker heating method and an electric cooker thereof. In order to solve the problems of low efficiency and slow heating in the prior art, threeor more than three open-loop circular electric heating tubes are arranged under a pot body in an aluminum-coated manner to annularly heat the bottom of the pot in a plurality of circles inside and outside, the pot body heats the liquid contained in the pot at intervals through the temperature difference between the inside and the outside of a vertical pipe by placing the vertical pipe, and the temperature difference interval heating is characterized by placing the vertical pipe which can be freely taken and placed, of which the height is smaller than the vertical depth of a lower opening inner cavity circle in the pot, and the inner cavity tangent circle diameter is equal to or larger than that of a second electric heating pipe from outside to inside in the middle of the bottom of the pot. The vertical pipe is circular, and the upper openings of the vertical pipe are waved openings which are alternately distributed in a circumferential concave-convex sequence. The energy-saving rapidelectric cooker heating method and the electric cooker thereof have the advantages of being high in electric heating efficiency, fast in temperature rise and beneficial to improving food quality.

Description

technical field [0001] The invention relates to an electric heating pot, in particular to an energy-saving and fast heating method for an electric heating pot and the electric heating pot. Background technique [0002] Existing commonly used electric heating pot is to cover the bottom of the pot with multiple electric heating tubes to provide heat source to the pot body. However, the inventors have found through long-term research that the bottom-covered electric heating pot with electric heating tubes has the disadvantages of low electric heating efficiency and slow temperature rise when heating liquid. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects of the prior art, and provide an energy-saving and rapid electric pan heating method and an electric heating pan thereof. [0004] In order to achieve the above object, the energy-saving and rapid electric pan heating method of the present invention is that th...
