Abstract

The utility model discloses an energy saving electric furnace which is suitable for industries, laboratories, and families. The utility model comprises a concave furnace plate, a furnace frame, and a heating wire wound in the furnace plate. The utility model is characterized in that a base plate is arranged on the furnace frame, the furnace plate is arranged on the base plate, a heat insulating layer is arranged on the furnace plate, and the heat is prevented from conducting outwards through the base plate. The utility model has the advantages of high heat efficiency, adjustable power, simple fabrication process, firmness, durability, and low cost.

Description

Energy saving electric furnace

The utility model belongs to a kind of electric calorifie installation, particularly a kind of miniature energy-saving electric furnace that is applicable to that industry, laboratory and family use.

Along with the raising with living standards of the people of developing rapidly of China's electric utility, various electric-heating cooking utensils are progressively come into average family.Although electromagnetic oven, cooking in microwave oven are totally quick, taste can not show a candle to the taste that the dish of frying out with strockle or iron pan is more suitable for people.Therefore, the electric furnace of direct-heating type remains the kitchen range of modernized family indispensability.

Now popular on the market a kind of electric furnace still be constant old patterns of what years, and owing to structural reason, the heat energy utilization rate is low, the secondary energy sources that make preciousness slatterning in vain.Also have a kind of electric furnace, heating wire is to be placed directly on the insulation material, and isolation is bonded on the metal chassis with little magnetic tube and finishes between the heating wire.Because the binding agent resistance to elevated temperatures is bad, little magnetic tube often comes off, and its service life is extremely short.

At the Chinese patent notification number is in " Concave electric stove " of CN2030297U, provide a kind of and can improve the civilian electric furnace that heat is imitated, it is made of concave surface stone or metal plate for standing a stove on as a precaution against fire, heating wire and grate, its advantage is a Concave electric stove heating circular bottom pot, can prevent that heat scatters and disappears and kettle temperature is evenly distributed, but its stone or metal plate for standing a stove on as a precaution against fire contacts with grate directly, therebetween heat leakage, influence it and add thermal effect, cause the thermal efficiency not high enough.

The purpose of this utility model is to provide a kind of convenient clean characteristics of traditional electric furnace that promptly keep, relative again energy savings, and the Energy-saving electric stove of long service life.

The utility model is achieved in that it has concave surface stone or metal plate for standing a stove on as a precaution against fire, grate and a dish to be placed on the interior heating wire of stone or metal plate for standing a stove on as a precaution against fire, its special character is that a chassis is installed on grate, said stone or metal plate for standing a stove on as a precaution against fire is installed on the chassis and a heat insulation layer is arranged therebetween, outwards conducts by the chassis to stop heat.

According to above-mentioned Energy-saving electric stove, be coated with the far ultrared paint layer at the stone or metal plate for standing a stove on as a precaution against fire upper surface, so that make a part of heat that heating wire conducts to stone or metal plate for standing a stove on as a precaution against fire excite far ultrared paint to produce far infrared, pass to calandria in the mode of radiation.

According to above-mentioned Energy-saving electric stove, said heating wire constitutes by two sections, and connects power end by power combination switch or semiconductor pressure regulator, regulates to realize different capacity.

Advantage of the present utility model is: thermal efficiency height, and adjustable power, and separate type is made on stone or metal plate for standing a stove on as a precaution against fire and chassis, it is convenient to change; Manufacture craft is simple, and is sturdy and durable, and cost is lower.

The drawing explanation:

Fig. 1 is the structural representation of this Energy-saving electric stove;

Fig. 2 is the vertical view of this Energy-saving electric stove;

Fig. 3-1,3-2 are the electrical schematic diagrams of this Energy-saving electric stove.

Below in conjunction with drawings and Examples the utility model is elaborated:

As shown in drawings, this Energy-saving electric stove has a grate 5, the chassis 4 that ceramic material is made is installed on grate 5, the stone or metal plate for standing a stove on as a precaution against fire 2 that heat-stable ceramic is made is installed on chassis 4, be placed with the heat insulation layer 3 that constitutes by heat-barrier material (can adopt ultra-fine fibre glass or rare earth heat-insulating material) between said chassis 4 and the stone or metal plate for standing a stove on as a precaution against fire 2, upper surface at stone or metal plate for standing a stove on as a precaution against fire 2 is coated with far ultrared paint layer 2a, heating wire 1 is installed on stone or metal plate for standing a stove on as a precaution against fire 2, said heating wire 1 is by two sections 1a, 1b constitutes, heating wire 1a, 1b alternately is coiled in the groove of heating plate 2, and connect power end by power regulating switch 6, as shown in Figure 3, said heating wire 1a, 1b can connect power supply by power combination switch 6a, to realize total power, half-power, 1/4 power ... regulate, said heating wire 1 also can pass through by controllable silicon 8, the semiconductor pressure regulator 6b that thyristor gating circuit 9 constitutes realizes that total power is to step-less adjustment between the zero energy.

Claims
