Abstract
The utility model relates to a multi-function and multi-purpose electric heating pot. Ceramic electric heating membranes are sintered outside the bottom surface of a burning pot. A bimetallic sheet switch which fixed outside the bottom surface of the burning pot serves as a heating-sensitive element; the different combination of the electric heating membranes is matched with a transfer switch and the double metal sheets switch, and consequently, a simple and sensitive electric circuit which is used for controlling temperature and regulating power can be formed. Even if the water in the electric-heating pot is dried, or the electric-heating pot without water is burned, the danger to damage a pot body can not happen. The utility model is provided with a manual control temperature shift, and realizes the multiple functions and multi purposes in different cooking methods of stewing, boiling, swilling, roasting, etc. in the electric-heating pot.
Description
The utility model relates to a kind of cooking apparatus, and it belongs to a kind of electric food warmer (international Patent classificating number: A47J217/086).
At present existing is the electric food warmer of heater with the Electric radiant Heating Film, generally all is that employing PTC is a temperature-sensing element, cooperates bidirectional triode thyristor, diac and several resistance, electric capacity to realize multi-functional and protective effect.Adopt this structure that electric food warmer is worked in each predetermined temperature range, easy to use, reliable, for electric food warmer provides a comparatively practical structure to superior, automation, intelligent development.But yet there is some deficiency in this structure, and promptly the bidirectional triode thyristor cost is higher, and auxiliary element is more, makes to be unfavorable for complex manufacturing using on simpler, popular electric food warmer.
The purpose of this utility model is: a kind of new temperature-sensing element is provided---bimetal release is beneficial to use on the popular electric food warmer simpler, and making with the Electric radiant Heating Film is the electric food warmer cost reduction of heater, the integrated artistic raising; The temperature control holding circuit is simple, can realize the multi-functional and protective effect of electric food warmer equally.
The purpose of this utility model is to realize like this; bimetal release closely contacts with the pot external body; be serially connected in the circuit by change-over switch and Electric radiant Heating Film; bimetal release has a pair of normally closed interlock that is driven by bimetal leaf; when pot surface temperature rises to the operating temperature of bimetal leaf; the bimetal leaf upset; and normally closed interlock is disconnected; cut off the electricity supply; when temperature of boiler drops to the recovery temperature of bimetal leaf; bimetal leaf is made war and is returned to normally off, and power supply recloses, thereby realizes protection and temperature control function; in addition; to make two or more sets as the Electric radiant Heating Film of electric heating body, be implemented in series connection in the circuit by change-over switch; in parallel or logical; disconnected state, and be aided with the bimetal release of different operating temperatures; thereby realize multi-functional; multipurpose.
Description of drawings.
Fig. 1 is a main cutaway view of the present utility model.
Fig. 2 is the utility model Electric radiant Heating Film shape and electrical schematic diagram.
1, pot cover, 2, the pot body, 3, base, 4, Electric radiant Heating Film, 5, bimetal release, 6, change-over switch, 7, electrode.
Below with reference to the accompanying drawings, in conjunction with the embodiments the utility model is described further.
Electric radiant Heating Film 4 is sintered into one with a pot body 2 in pot body 2 outsides, utilizes electrode 7 to make Electric radiant Heating Film 4 be divided into three groups, and bimetal release 5 utilizes binding agent to be bonded in pot body 2 bottoms, and change-over switch 6 connects bimetal release 5 and electrode 7 respectively, is connected in power supply.The connecting point position of conversion change-over switch 6, make Electric radiant Heating Film 4 realize the switching of interior ring respectively, the string of outer shroud and etc. four kinds of states, when electric food warmer is worked under the state of setting up in advance, bimetal release 5 cuts off with the variation of pot body 2 surface temperatures or connects power supply, electric food warmer is cooked, according to the difference of culinary art object and method in certain temperature range to food, the position of conversion change-over switch 6 is to satisfy different culinary art requirements.In the present embodiment bimetal release 5, if use the bimetal release 5 of two or more different operating temperatures and, electric food warmer is worked in different temperature ranges by change-over switch 6.Because bimetal release 5 has limited the temperature on pot body 2 surfaces,, pot body 2 and Electric radiant Heating Film 4 damaged because of temperature is too high when occurring dryouting, when dry combustion method or crust pot phenomenon, entering the protected by temperature limitation state automatically.Pot body 2 can be the shape of the material electric heating film 4 that can be sintered into one and have insulating properties with Electric radiant Heating Film 4 such as enamel, pottery, glass except that the described arc combination of present embodiment, also can do the combination of squarely, annular or multiple geometry according to form of pot bottom.In addition, in parallel as in the temperature control holding circuit, increasing a diode with bimetal release 5, can make electric food warmer power decay 50% automatically after reaching the control temperature; Be serially connected in the circuit as cooperating, can increase selective power rating with change-over switch 6.
The utility model is owing to adopted bimetal release 5 to be temperature-sensing element, and the temperature control holding circuit is simple, bimetal release 5 prices are low, and the manufacturability of electric food warmer is improved, and has reduced cost simultaneously.The various combination of Electric radiant Heating Film 4 matches with change-over switch 6 and bimetal release 5 and has constituted temperature control adjusting power circuit, has realized the stewing of electric food warmer, boils in a covered pot over a slow fire, rinses, difference such as stewing cooks multi-functional, the multipurpose of appointing method.Help on simpler, popular electric food warmer, using.
