Problems solved by technology

[0002] Existing electric heating cooking devices such as electric pressure cookers and electric rice cookers generally use electric heating plates or electric heating tubes for heating. Both methods have certain defects. The plate heats up the inner pot; due to the contact heat transfer between the separate inner pot and the electric plate, its thermal efficiency is not high, and the electric heating device has the problem of heat upshoot after power failure, it is difficult to achieve precise control in control, which affects cooking Effect; electric heating tube heating type: it welds the heating tube at the bottom of the ordinary pot body, and it relies on the electrode switch to realize electrical connection with the bottom to realize the self-heating electric heating plate heating type of the pot body. Since the electric heating tube and the pot body are welded together, the electric heating tube If it is exposed outside, the pot body cannot be immersed in water for cleaning, causing inconvenience to consumers

Embodiment 1

[0023] refer to Figure 1 to Figure 3 , an electric heating cooking device, including a base 1, an upper cover 2 fastened on the base 1 and an inner pot 3 placed in the base 1, the outer surface of the inner pot 3 is covered with a heat preservation cover 4, and the electric heating element 5 is fixedly connected to the The bottom of the inner pot 3 outer surface is fixed by welding in this embodiment.

[0024] Different from general electric heating cooking devices, the controller and the pot body of this embodiment are set separately, and the outer wall of the base 1 is detachably connected with the mobile controller 6 . The specific connection method is: a plug-in unit is set between the outer wall of the base 1 and the mobile controller 6 , a split electrical connector 7 is set at the contact position, and the mobile controller 6 is electrically connected to the base 1 through the split electrical connector 7 . The base 1 is provided with a handle 1-1, and the mobile cont...

Embodiment 2

[0029] The difference between this embodiment and Embodiment 1 is that the electrical connector 7 is a magnetic suction type electrical connector, the base 1 is provided with an upper electrode seat 7-1, and the upper electrode seat 7-1 is provided with an upper electrode 7-1. 2. The mobile controller 6 is equipped with a lower electrode holder 7-3 and a movable lower electrode 7-4, and the upper electrode holder 7-1 and the lower electrode holder 7-3 are respectively equipped with magnets with opposite polarities. (7-8, 7-9), when the upper electrode holder and the lower electrode holder are sucked together, the lower electrode 7-4 is in contact with the upper electrode 7-2. The lower electrode seat 7-3 is also provided with an electrode baffle 7-7 that exposes the lower electrode under the action of plugging movement, and the electrode baffle 7-7 is provided with an elastic reset mechanism that closes the lower electrode 7-4 in a natural state .

Abstract

An electric heating cooking device comprises a base, an upper cover buckled on the base as well as an inner pot arranged in the base, wherein a heat-insulating cover coats an outer surface of the inner pot; an electric heating element is fixedly connected to the bottom of the outer surface of the inner pot; a movable controller is detachably connected to the outer wall of the base; an inserting unit is arranged between the outer wall of the base and the movable controller; a split electric connector is arranged at the contacting position of the inserting unit; the movable controller is electrically connected with the base through the split electric connector; the electric connector is a magnetic suction type electric connector; an upper electrode holder is arranged on the base; an upper electrode is arranged in the upper electrode holder; a lower electrode holder and a movable lower electrode are arranged in the movable controller; magnets which are opposite and have opposite polarities are respectively arranged in the upper electrode holder and the lower electrode holder; and when the upper electrode holder is sucked with the lower electrode holder, the lower electrode is contacted and conducted with the upper electrode. The electric heating cooking device disclosed by the invention is favorable in heat-transferring and heat-insulating effect; the electric heating element is not exposed and can be integrally and quickly cooled; the service life of the controller is long; and the electric connector is simple in structure and reliable in action.

Description

technical field [0001] The invention relates to a small kitchen appliance, in particular to an electric heating cooking device in which a heating unit and an inner pot are integrated. This application is a divisional application of the electric heating cooking device with the patent application number 201110112477.5 submitted on April 30, 2011. Background technique [0002] Existing electric heating cooking devices such as electric pressure cookers and electric rice cookers generally use electric heating plates or electric heating tubes for heating. Both methods have certain defects. The plate heats up the inner pot; due to the contact heat transfer between the separate inner pot and the electric plate, its thermal efficiency is not high, and the electric heating device has the problem of heat upshoot after power failure, it is difficult to achieve precise control in control, which affects cooking Effect; electric heating tube heating type: it welds the heating tube at the ...
