Abstract

The utility model discloses a multipurpose electric heating range. In the multipurpose electric heating range, on the basis of an electronic rice cooker, a casing is divided into a casing rack and an insulating sleeve which can be movably assembled, and an original thermostat is additionally provided with a manual switch and a calorstat whose contact can be automatically disconnected when the temperature is well above 98+-2DEG. C; so the multipurpose electric heating range keeps the functions and advantages of the original electronic rice cooker; the multipurpose electric heating range can be matched with various kitchen utensils, so the effect of one range with various functions is obtained; also, the multipurpose electric heating range has the temperature self-control function under the condition of multiple uses.

Description

Multipurpose electric heating range

The utility model is a kind of electric range of using more, and it belongs to stove or kitchen range with the electric energy heating, the configuration that particularly relates to the direct radiant heating of heating element heater and have temperature control equipment.It comprises that electric hot tray is fixed in the shell frame, be equipped with temperature controller under the dish, be serially connected with between 220V civil power and electric hot tray after the bimetal thermostat that the magnetic steel temperature limiter of said temperature controller loss of excitation during by 103 ℃ contact when being higher than 70 ℃ disconnects voluntarily is in parallel and is connected and constitute.

Along with the development of China's electric utility and improving constantly of people's living standard, various household electrical appliance, particularly various cooking electrical equipment enters people's family in large quantities, and electric cooker is convenient and practical, durable in use and gain great popularity with it.Its formation is to cooperate use automatically rice is boiled and is incubated electric hot tray and the temperature controller of being made up of temperature limiter and thermostat.Weak point be electric cooker only boil the special cooker of meal dry under normal conditions as family and can not or be not easy to boil water, soup, gruel etc., if purchase the cooker investment that other electric-heating cooking utensil then not only increases family kitchen again, and because of its specificity all can take more kitchen area than the good general, and their security reliability owes poor.In addition, owing to the structure of electric cooker make its thermal source need with special-purpose in the supporting use of pot make its can not with the past or at present cooking utensils such as the pot purchased when main by coal or liquefied petroleum gas or coal gas of the most residents' of China cooking thermal source, kettle be used, thereby can not give full play to the health, convenience of electric cooker electricity consumption, to the free of contamination advantage of air, can not further improve their comprehensive utilization ratio, it is made the best use of everything.

The purpose of this utility model be to avoid above-mentioned the deficiencies in the prior art part and provide a kind of suitable face width, can be temperature automatically controlled use electric range more.

The purpose of this utility model can reach by following measure: the electric cooker shell of existing built-in electric hot tray and temperature controller is resolved into the shell frame and the muff that can assemble movingly, to adapt to the needs that various types of pot, kettle all can use the electric cooker thermal source.In the temperature controller be higher than 70 ℃ the time contact bimetal thermostat that disconnects voluntarily two ends be connected in parallel to hand switch, and be serially connected with the thermostat that the contact disconnects voluntarily when being higher than 98 ± 2 ℃ between they and the electric hot tray, use the thermal source of electric cooker to boil water or the phenomenon of overflowing that neither can occur boiling when soup or gruel can be incubated again with box lunch.

The purpose of this utility model can also reach by following measure: the bottom of muff can be the concave station of contraction, also can be the boss of expansion, so just can easily it directly be fastened on the shell frame.The card of electric hot tray can be made plane to match with the bottom of various cookers better and to improve the efficient that heat is transmitted.The thermostat that the contact disconnects voluntarily when being higher than 98 ± 2 ℃ can select for use double-metal sheet type or PTC formula all can.

The utility model has following advantage compared to existing technology:

1, the function and the advantage that had both kept former electric cooker, again can be easily match and use and obtained the effect of multi-purpose cooker with various types of cookers, thereby improved the comprehensive utilization ratio of kitchen range, cooker, the investment that has correspondingly reduced the family kitchen apparatus with reduce taking of kitchen area.

2, realized that the temperature under the multiple use situation controls automatically, improved family kitchen apparatus automation of operation degree.

Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of basic structure schematic diagram of the present utility model.

Fig. 2 is the electrical schematic diagram of temperature controller in the utility model.

With reference to Fig. 1 and Fig. 2, be equipped with electric hot tray 2 and temperature controller 3 in the shell frame 1 of annular; The temperature actuated panel 5 and supporting leg 6 which is provided with supply socket 4, hand switch K3, magnetic steel temperature limiter button K1, indicator lamp L is equipped with in shell frame 1 outside.On the muff 7 of annular handle 8 is housed, cover 7 can assemble mutually movingly with interior pot 9.The bottom of cover 7 also can be the boss platform 11 of expansion for the round concave table 10(that shrinks), it is of a size of and can assembles movingly mutually with the top of shell frame 1.The bimetal leaf K22 that the contact disconnected voluntarily when serial connection was higher than 98 ± 2 ℃ again after the bimetal leaf K21 that temperature controller 3 contact when being higher than 70 ℃ disconnects voluntarily and hand switch K3 were in parallel and are connected; Being connected in series the parallel circuit that electric hot tray 2 and indicator lamp L formed after the magnetic steel temperature limiter K1 that the contact disconnected when afterwards, they were with 103 ℃ is connected in parallel again constitutes.

When dryouting meal, press (connection) K1, and disconnect hand switch K3.After treating that the meal boiled water is done, because of the temperature of sensing magnet steel temperature limiter K1 has reached curie point, promptly 103 ℃ of losss of excitation and voluntarily end open, this moment, the temperature of electric hot tray 2 also was about 103 ℃, K21, K22 all disconnect voluntarily.When the meal temperature is lower than 103 ℃ and when being higher than 70 ℃, K22 connects and K21 still disconnects, and K21 connects the back 220V civil power electric hot tray 2 of just can flowing through voluntarily its intensification is heated meal when the meal temperature is lower than 70 ℃.

When boiling water or when soup or gruel, only needing hand switch K3 closed gets final product.In water or soup or gruel boiled when pot,, K22 disconnects voluntarily; When the temperature of heating object was lower than 98 ± 2 ℃, K22 connected again voluntarily, made the 220V civil power flow through electric hot tray 2 to its heating that heats up.
