Abstract

The utility model discloses an electrical pressure boiler being able to improve the heat conductivity performance of the earthen inner boiler, which comprises an outer boiler (1), a sandy and earthen inner boiler (2) and a heating plate (3) arranged at the bottom of the inner boiler (2); the bottom of the inner boiler (2) is provided with a heat conductive layer (4), the heat conductive layer (4) is a heater conductive paint coated on the bottom of the inner boiler (2) for preventing the air explosion noises after the bottom of the inner boiler (2) adsorbing water during heating. The utility model can prevent the chemical reaction generating between metal and food being harmful to human body, and can keep the flavor of the food cooked in the Chinese traditional sandy and earthen boiler; at the same time, the utility model can keep the temperature for a long time and the inner boiler is not easy to break with receiving even heat at the bottom of the inner boiler; besides, the heat spreading is quick, the time for cooking food is short, therefore the utility model is a beneficial and healthy kitchen instrument being able to save energy and time.

Description

A kind of electric pressure cooking saucepan that can improve pot heat conductivility in the ceramic
Technical field
The utility model relates to the electric pressure cooking saucepan field, particularly a kind of electric pressure cooking saucepan that can improve the interior pot heat conductivility that ceramic or sand material make.
Background technology
In the prior art, the kind of electric pressure cooking saucepan is of all kinds, but the interior pot of electric pressure cooking saucepan is owing to will bear high temperature and high pressure, pot generally all is that aluminium matter or stainless steel and other metal materials are made in it, this aluminium matter or stainless in the pot heat-transfer effect good, be heated fast, but because metallic article under high-temperature condition, contact the generation chemical reaction with food, can produce harmful chemical substance, be unfavorable for that the people's is healthy; The mouthfeel of the food that pot cooked out in secondly metal material was made is bad, and the taste of food that does not have the pot body of ceramic or chiltern to cook out is pure; The interior pot heat insulation effect made of this metal material is bad at last, and food cooking back well can make the mouthfeel of food better if temperature retention time is long.If but adopt chiltern, ceramic material to make the interior pot of electric pressure cooking saucepan, then because the thermal conductivity ratio metal material of material is low, and its inwall is thicker, so heat conductivility is low than pot in the metal, and cooking food is taken time longer; The interior pot bottom made of chiltern, ceramic easily absorbs water in addition, and when when heat-generating disc heats, the moisture content of absorption discharges steam when being heated, and can produce gasification reaction and produce quick-fried gas noise by the contact-making surface with the bottom of interior pot on the heat-generating disc surface.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of electric pressure cooking saucepan is provided, this electric pressure cooking saucepan both can have been avoided metal to contact with food producing chemical reaction and to the harm of human body, keep the traditional marmite of China or the local flavor of buckpot cooking food, can obviously improve heat conductivility again, the cooking food required time is short, is a kind of kitchen utensils of energy-and time-economizing.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of electric pressure cooking saucepan that can improve pot heat conductivility in the ceramic, comprise interior pot that outer pot, chiltern or ceramic material are made and the heat-generating disc that is located at interior pot bottom, be provided with heat-conducting layer in the bottom of interior pot.
Above-mentioned heat-conducting layer is the heat-conductive coating of pot bottom in being coated in.
The metallic film of pot bottom in above-mentioned heat-conducting layer also can be and directly is plated in.
Above-mentioned heat-conducting layer also can be the tinsel of pot bottom in being bonded in by high temperature adhesive, and in addition, this heat-conducting layer can also be the metal mesh shaped structure of pot bottom in being bonded in by high temperature adhesive.
For the bottom heating surface area that makes in the electric pressure cooking saucepan pot is big, the area of above-mentioned heat-conducting layer is not less than the contact-making surface area that heat-generating disc and interior pot bottom connection touch.
The utility model compared with prior art mainly has the following advantages:
(1) the utility model will be owing to will have the interior pot of the electric pressure cooking saucepan that metal material makes now and be improved to by chiltern or ceramic material and make, can effectively avoid metallic article to contact and produce harmful chemical substance with food, use the interior pot cooking food of chiltern, ceramic simultaneously, can keep the traditional marmite or the local flavor of buckpot cooking food;
(2) the utility model is provided with heat-conducting layer at interior pot bottom, has improved the heat conductivility of pot in the ceramic, and heat-transfer area is big, and it is fast to conduct heat, and the time that cooking food needs is short, is a kind of kitchen utensils of energy-and time-economizing.
(3) the utility model heat-conducting layer is the heat-conductive coating of pot bottom in directly being coated in, and can prevent that the interior pot bottom suction back of chiltern, ceramic from producing quick-fried gas noise when heating.

Fig. 2 is an A place zoomed-in view among Fig. 1;
Fig. 3 is the structural representation of the utility model embodiment two;
Fig. 4 is a B place zoomed-in view among Fig. 3.
The specific embodiment
Embodiment one:
As shown in Figure 1 and Figure 2, the utility model comprises interior pot 2 that outer pot 1, chiltern or ceramic material are made and the heat-generating disc 3 that is located at interior pot 2 bottoms, bottom at interior pot 2 is provided with heat-conducting layer 4, for easy to process, the heat-conductive coating of the bottom of a pan face in this heat-conducting layer 4 can be and is coated in, use this heat-conductive coating, pot bottom suction in can preventing and the quick-fried gas noise that when heating, produces, heat-conducting layer 4 also can be the metallic film of pot 2 bottoms in directly being plated in; Perhaps, heat-conducting layer 4 is the tinsel of pot 2 bottoms in being bonded in by high temperature adhesive, can also be the woven wire that evenly gathers of pot 2 bottoms in being bonded in by high temperature adhesive.For the heat that makes heat-generating disc 3 can be even and whole fast pass through heat-conducting layer 4 pass in pot 2 bottom, the area of heat-conducting layer 4 is not less than the contact-making surface area that the bottom connection of heat-generating disc 3 and interior pot 2 touches.
Embodiment two:
Present embodiment and embodiment one structure are basic identical, its difference is: shown in Fig. 3 and 4, heat-generating disc 3 is the peviform structure, the heat-conducting layer 4 that is located at interior pot 2 bottoms also is provided with heat-conducting layer 4 on the interior pot 2 bottom lateral walls that contact with peviform heat-generating disc 3 sidewalls except pot 2 bottom surfaces in being distributed in, the area of heat-conducting layer 4 distributions is bigger like this, the heat of heat-generating disc 3 will pass on the interior pot 2 faster, it is fast to conduct heat, and the cooking food required time is shorter, be a kind ofly more save time, energy-conservation kitchen utensils.
