Abstract
The invention relates to a cooking utensil with an upper cover cooling device, which comprises a pot body, an inner pot in the pot body, a pot cover above the inner pot, an upper cover hinged with the pot body, a main control circuit and a heater. The invention has the beneficial effects that: because the upper cover is internally provided with the cooling device consisting of the radiating element and the air duct, the cooking utensil can heat and cook food in the inner pot through the heater and can also cool the food in the inner pot through the upper cover cooling device; and if the cooking utensil is an electric pressure cooker, the pressure in the inner pot can be reduced by cooling the food and the gas in the inner pot, so that the cover can be opened quickly. The invention has simple structure, convenient use and high cooling efficiency.
Description
Technical field
The present invention relates to a kind of cooking apparatus, particularly a kind of cooking apparatus that has upper cover cooling apparatus.The renovation technique that belongs to cooking apparatus.
Background technology
The most of cooking apparatus that comprises electric cooker, electric pressure cooking saucepan, slow cooker etc. at present, a having heaters wherein can only be to the food heating and can not be initiatively to food cooling, and therefore, there is following shortcoming in it:
1) food can slowly be lowered the temperature under cooking temp, naturally so food can keep higher temperature in one period long period after heating finishes.When the user thinks at once to enjoy food also the very important person be the attenuating of the temperature of food, operate more loaded down with trivial details.
2) food can keep higher temperature in one long period, and this can make some overdo as food cookings such as fish, rice, gruel, causes the food overdo, influences eating mouth feel, reduces food nourishment composition.
3) for electric pressure cooking saucepan, because after the heating end, kettle temperature surpasses local boiling point, in the pot pressure is arranged still, the buckling state of pot cover and interior pot can't be removed, and enjoys food so the heating end can't be opened pot cover; Must allow kettle temperature descend naturally, but the stand-by period is oversize; Perhaps manual exhaust allows pot inner pressure descend, and such operation danger close is scalded easily.
For solving the problem that prior art exists, a kind of electric pressure cooking appliance is disclosed among the Chinese patent ZL200620060234.6, be provided with cooling device between wherein outer pot bottom and the pot body, the corresponding cooling device of bottom of pot body is provided with air outlet, be provided with wiring board in the pot body, pressure control mechanism is electrically connected with wiring board, and wiring board is electrically connected with cooling device.Though this electric pressure cooking appliance pot bottom and pot outside is provided with cooling device between the body, the corresponding cooling device of bottom of pot body is provided with air outlet, and it does not have the cooling air channel between loam cake and the shell; So wind can only enter from the very little gap between loam cake and the shell, the shortcoming of its existence is as follows: 1) air quantity is very little; 2) can not cool off pot cover; 3) can not be cooled to liquid state contact more steam with pot cover; So cooling effect is limited.
A kind of electric pressure cooking appliance is disclosed among the Chinese patent CN200810028922.8, particularly a kind of cooking apparatus that has cooling air channel, the control circuit that also is equiped with cooling fan and is electrically connected with cooling fan and heater in shell or the loam cake; Wherein be provided with the space between outer pot and the interior pot, be provided with between loam cake and the shell and pass loam cake and space perforation, and pass the cooling air channel of shell, be equiped with at least one fan on the cooling air channel.Though this cooking apparatus can cool off pot cover and interior pot simultaneously, the pot cover surface that wind directly never is provided with cooling device is flow through, so heat dissipation capacity is limited, cooling effect is not good.
Summary of the invention
The objective of the invention is to overcome the problems referred to above of prior art and provide a kind of except can be by heater the heating of the food in the interior pot, can also be the cooking apparatus that has upper cover cooling apparatus of cooling fast of the food in the interior pot.
The technical scheme that realizes the object of the invention is: a kind of cooking apparatus that has upper cover cooling apparatus, include interior pot in the body of a pot body, pot, interior pot top pot cover, with hinged loam cake, governor circuit and the heater of pot body, it is characterized in that being provided with between loam cake and the pot cover and constitute the air channel at interval, the air channel is provided with air inlet and air outlet, pot cover is provided with heat dissipation element, heat dissipation element is between air inlet and air outlet, and heater links to each other with governor circuit.
Above-mentioned heat dissipation element is made up of a plurality of fin, and the air channel is by the space between the fin.
For improving radiating efficiency, be equiped with fan in the above-mentioned air channel, fan links to each other with governor circuit.
For improving the radiating efficiency of fan, said fans is between heat dissipation element and air outlet.
Said fans can be horizontally fixed on the top in air channel, and is positioned at the top of heat dissipation element.
Said fans also can be erect and be fixed in the air channel, is positioned at the side of heat dissipation element.
Said fans can also be located at air inlet or/and the position of air outlet.
For increasing contact area between above-mentioned heat dissipation element and the pot cover to improve the heat transfer efficiency between pot cover and the heat dissipation element.Between heat dissipation element and pot cover, be provided with the soft thing of heat conduction.As: heat conductive silica gel or heat-conducting silicone grease.
Above-mentioned heat dissipation element and pot cover have multiple method of attachment, wherein connect the simplest and firm with screw.
Beneficial effect of the present invention is: the present invention is owing to have heat dissipation element and the cooling device of air channel composition in the loam cake, cooking apparatus can also cool off the food in the interior pot by upper cover cooling apparatus except being undertaken the heating cooking by the food in the internal pot of heater; And if food and gas that cooking apparatus is an electric pressure cooking saucepan then to be cooled off in the interior pot can also make the pressure in the interior pot descend, so that open pot cover fast.The present invention is simple in structure, and is easy to use, the cooling effectiveness height.
