Electric cooking pot

Abstract

An electric cooking pot has a main body, a pot body, two electric heating elements and two knobs. The pot body is mounted on a top of the main body. Two cooking recesses are formed on the pot body. The two electric heating elements with different heating powers are attached to the two cooking recesses respectively. One of the heating elements is strip-shaped and substantially forms a quadrilateral to avoid underheat near edges of the corresponding cooking recess. The knobs protrude from the main body. The two heating elements are respectively controlled by the two knobs. The two cooking recesses and a center of the knobs are arranged along a straight line for ease of use. A length of a contour of the main body reduces gradually from bottom to top of the main body. Therefore, users can enjoy two freshly prepared dishes at same time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) With reference to FIGS. 1 and 2, an electric cooking pot in accordance with the present invention comprises a main body 10, a pot body 20, a control module 30 and two electric heating elements. In a preferred embodiment, the electric cooking pot further comprises two overheat sensors 50.

(8) With further reference to FIGS. 2, 5 and 6, the main body 10 is a casing with a square cross section, and four lateral surfaces of the main body 10 incline toward a center of the main body 10, such that a length of a contour of the main body 10 reduces gradually from a bottom of the main body 10 to a top of the main body 10. Heat inside the main body 10 can be concentrated on the top of the main body 10, which improves the cooking efficiency. To be precise, the main body 10 has a front wall 11, a rear wall 12, a left side wall 13 and a right side wall 14. The front wall 11 and the rear wall 12 are located on two opposite sides of the main body 10 respectively and incline toward each other. The left side wall 13 and the right side wall 14 are located on the two opposite sides of the main body 10 respectively and incline toward each other. An imaginary line connecting the front wall 11 and the rear wall 12 is perpendicular to an imaginary line connecting the left side wall 13 and the right side wall 14.

(9) With further reference to FIGS. 1, 2 and 5, the pot body 20 is mounted on top of the main body 10. A first cooking recess 21 and a second cooking recess 22 are formed on the pot body 20. In a preferred embodiment, a depth of the first cooking recess 21 is shallower than that of the second cooking recess 22 and is suitable for pan-frying or grilling. The depth of the second cooking recess 22 is relatively deeper, and is suitable for cooking personal fondue or boiling soup.

(10) The control module 30 is mounted in the main body 10, and has a manual operating part 31. The manual operating part 31 protrude from the main body 10, and to be precise, the manual operating part 31 has two knobs. The manual operating part 31, the first cooking recess 21 and the second cooking recess 22 are arranged along a straight operating line L for ease of use. In a preferred embodiment, a center of the two knobs of the manual operating part 31, the first cooking recess 21 and the second cooking recess 22 are arranged along a straight operating line L.

(11) In a preferred embodiment, the first cooking recess 21 and the second cooking recess 22 are oblong recesses extending along a length direction, which is suitable for accommodating strip-shaped food ingredients such as sliced meat. The length direction is perpendicular to the operating line L for ease of use.

(12) With further reference to FIGS. 3 to 5, the electric heating elements are mounted in the main body 10 and attached to the pot body 20. The two electric heating elements are respectively located under the first cooking recess 21 and the second cooking recess 22. Heating powers of the two electric heating elements are different, which allows a user to cook two dishes that require different heating powers at the same time. The electric heating elements are electrically connected to the control module 30 so that the user can control the electric heating elements. To be precise, the two heating elements are respectively controlled by the two knobs of the manual operating part 31. However, the number of the knob can be one.

(13) In a preferred embodiment, the two electric heating elements are respectively a first electric heating element 41 and a second electric heating element 42. The first electric heating element 41 and the second electric heating element 42 are located under the first cooking recess 21 and the second cooking recess 22 respectively. Each electric heating element is an electric heating tube in the shape of a strip. The length of the second electric heating element 42 is greater than the length of the first electric heating element 41, so that the second cooking recess 22 has higher heating power than the first cooking recess 21.

(14) Concerning the specific shape of the first electric heating element 41, in a preferred embodiment, the strip-shaped first electric heating element 41 substantially forms a quadrilateral. The first electric heating element 41 has two first straight sections 411 and two second straight sections 412. The first straight sections 411 extend along the length direction of the first cooking recess 21, and are disposed apart from each other in order to distribute heating power uniformly across the bottom of the first cooking recess 21. The two second straight sections 412 extend along a direction that is perpendicular to the first cooking recess 21, i.e., the operating line L. The two second straight sections 412 are attached to a bottom surface of the first cooking recess 21, and are located adjacent to two opposite edges of said bottom surface respectively, wherein said two opposite edges are arranged along the length direction of the first cooking recess 21. The two second straight sections 412 enhance the heating power near said edges and avoid underheat near said edges.

(15) Concerning the specific shape of the second electric heating element 42, in a preferred embodiment, the strip-shaped second electric heating element 42 substantially forms an S curve. The second electric heating element 42 has three first straight sections 421. The first straight sections 421 extend along the length direction of the second cooking recess 22, and are disposed apart from each other. In a preferred embodiment, a distance between two adjacent first straight sections 421 of the second electric heating elements 42 is shorter than a distance between two adjacent first straight sections 411 of the first electric heating elements 41, so that the heating power of the second cooking recess 22 is larger than the heating power of the cooking recess 21.

(16) In a preferred embodiment, a first engaging recess 23 and a second engaging recess 24 are formed in the bottom of the pot body 20. The first engaging recess 23 and the second engaging recess 24 are located under the first cooking recess 21 and the second cooking recess 22 respectively. The first electric heating element 41 and the second electric heating element 42 are engaged in the first engaging recess 23 and the second engaging recess 24 respectively to enlarge the contact area between the heating elements and the pot body 20, which in turn improves the heating efficiency.

(17) The two overheat sensors 50 are attached to the bottom of the pot body 20 and electrically connected to the control module 30. The overheat sensors 50 forcefully disconnect the power of the heating element when temperature of the first cooking recess 21 or the second cooking recess 22 is too high. Heat-generated damage is prevented by the overheat sensors 50. However, the number of the second cooking recess 22 is not limited to two, and there can be only one overheat sensor 50.

(18) In summary, two cooking recesses are formed on the pot body. The two cooking recesses are heated up by two electric heating elements with different heating powers. Therefore, two different dishes can be cooked using the two cooking recesses respectively at the same time. The two cooking recesses and the manual operating part of the control module are arranged along a straight line for ease of use.

(19) Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
