Abstract

The utility model relates to an electric heater. The electric heater adopts a spherical surface concave disk on a base. Slot lines by which moderate temperature resistance wires and low temperature resistance wires are placed are arranged on the spherical surface concave disk. A moderate temperature switch and a low temperature switch are connected to the end parts of the moderate temperature resistance wires and the low temperature resistance wires. The utility model has the advantages of simple structure, convenient operation and energy saving, and the heat quantity is concentrated. The utility model is suitable for frying vegetables as well as braising vegetables for a long time.

Description

Electric heater

The utility model relates to a kind of family expenses electric heater field.

The electric furnace of usefulness, the heating chassis of electric frying pan generally are flat or convex types at present, though more suitable, heat is very unconcentrated, only supply with the very little a part of heat in the bottom of a pan as flat electric heater, partly because the chassis is distant apart from pot, spread heat has been wasted a part of electric energy for all the other.If when needing and can not control that it is energy-conservation with little fire.It is first-class that the electric heater of convex type can only be used in electric chafing dish.For overcoming the problems referred to above, the utility model has designed a kind of electric heater with high, medium and low third gear, has solved spread heat, wastes the situation of a part of electric energy.And this electric heater rate of warming is fast, and heat is concentrated, and promptly is applicable to quick cooking, is applicable to the long period stew again, can also be used for little fire.

The purpose of this utility model provides a kind of electric heater with spherical groove, and this device rate of warming is fast, and heat is concentrated, and promptly is applicable to quick cooking, is applicable to the long period stew again.

The utility model is achieved in that electric heater is that the recessed dish of sphere is installed on base, the line of rabbet joint that on the recessed dish of sphere, has warm resistance wire and low-temperature resistance silk in the placement, warm switch and low-temperature switch during the end of middle temperature resistance wire and low-temperature resistance silk is connected with.The recessed dish of the base of electric heater and sphere is made with refractory insulating material, and base also available metal material is made.

During use, when needs high temperature, can with in, low-temperature switch connects simultaneously, in making, the low-temperature resistance silk generates heat simultaneously, as need with in during temperature, low-temperature switch can be disconnected, warm switch gets final product in the connection.During as need low temperature, middle temperature switch can be disconnected, can use low-temperature heat.

The utility model is compared with existing technology, and this is simple in structure, and is easy to use, has heat and concentrates, and can save a part of energy, is applicable to quick cooking, is applicable to the long period stew again.

The concrete structure and the embodiment of electric heater of the present utility model are provided by the following drawings.

Fig. 1 is the general structure schematic diagram of the novel electric heater of this reality.

Fig. 2 is the vertical view of the general structure of the utility model electric heater.

Below in conjunction with accompanying drawing this reality novel concrete structure and embodiment are done with further instruction.

See shown in Fig. 1,2: electric heater is to adopt to have a recessed dish 2 of sphere on base 1, the line of rabbet joint 3 that on the recessed dish 2 of sphere, has warm resistance wire 4 and low-temperature resistance silk 5 in the placement, warm switch 6 and low-temperature switch 7 during the end of middle temperature resistance wire 4 and low-temperature resistance silk 5 is connected with.

The recessed dish 2 usefulness refractory materials of the base 1 of electric heater and sphere are made, and base 1 also available metal material is made.

In warm switch 6 and low-temperature switch 7 be both on base 1.The line of rabbet joint 3 number of turns on the spherical groove 2 in, the high or low power of low-

temperature resistance silk

4,5 decides.And the line of rabbet joint 3 in order in fixing, low-

temperature resistance silk

4,5, make to keep the good insulation distance between the resistance wire and the bottom of a pan.

During use, when need are used high temperature, can with in, low-temperature switch 6,7 connects simultaneously, in making, low-

temperature resistance silk

4,5 generates heat simultaneously.As need with in when temperature, low-temperature switch 7 can be disconnected, warm switch 6 gets final product in the connection.During as need low temperature, middle temperature switch 6 can be disconnected, can use low-temperature heat.

Claims

1, a kind of electric heater, it has flat or convex protrusion formula and resistance wire constitute, it is characterized in that, on base 1, has a recessed dish 2 of sphere, the line of rabbet joint 3 that on the recessed dish 2 of sphere, has warm resistance wire 4 and low-temperature resistance silk 5 in the placement, warm switch 6 and low-temperature switch 7 in the end of middle temperature resistance wire 4 and low-temperature resistance silk 5 is connected with.
