Abstract

An electric water pot comprises a cover, a hull, an electric heater and a base; the cover and hull are made of at least two or more than two pieces of interlayer and a cavity between the two pieces of interlayer is designed in a state of heat insulation; the cover and hull contact each other closely; the electric heater is arranged in the hull and the hull bottom is covered with a motherboard. The utility model can effectively prevent the dispersion of heat to realize the function of energy saving and heat insulation; the utility model is equipped with an anti-radiation aluminum film which can prevent heat from radiating to the outside of the hull and enhance the heat insulation effect; in this way, boiled water can be directly left in the hull for heat insulation.

Description

The insulation electric water heater

The utility model belongs to a kind of electric kettle (pot), particularly a kind of electric kettle that is incubated (pot).

At present, general electric hot water container generally is made of kettle body, electric heating assembly, base, and the kettle body is made of the housing of individual layer, does not possess heat insulation function.In the process of heating up water,, and can prolong the time of heating up water from housing, water must be poured in other cool-bag after water is boiled and just can be incubated because heat energy constantly distributes.

The purpose of this utility model provides a kind of electric kettle that is made of multilayer shell, to realize the heat insulation function of electric kettle.

The utility model comprises lid, housing, electric heater, base, lid, housing constitute by two-layer at least or two-layer above interlayer, inner chamber between the interlayer is state of thermal isolation, lid, housing are tight contact shape, electric heater places in the housing, and housing bottom is covered by base and is the sealing shape.

The utlity model has following advantage:

1. the utility model is multilayer (more than a two-layer or two-layer) housing, vacuumizes between housing and the housing or fills heat-barrier material such as polyurethane and carry out heat insulationly, can stop distributing of heat energy effectively, thereby reach effect energy-conservation, insulation.

2. radiation proof aluminium film is housed between the utility model housing and the housing, can stops heat energy, thereby strengthen heat insulation effect to the housing external radiation.

3. because the utility model possesses heat insulation function is arranged, boiling water can directly be stayed in the housing and be incubated.

4. the utility model is the same with other cool-bag, slowly cooling in the insulating process, and directly energising can make water boiling more rapidly.

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is the utility model embodiment device schematic diagram;

Accompanying drawing 3 is accompanying drawing 1 a local X enlarged diagram;

Accompanying drawing 4 is accompanying drawing 1 a local Y enlarged diagram;

As shown in Figure 1, the utility model comprises lid (1,2,3), housing 4, electric heater 6, base (5,9), lid (1,2,3), housing 4 constitutes by two-layer at least or two-layer above interlayer, the inner chamber between the interlayer is state of thermal isolation, lid (1,2,3), housing 4 is tight contact shape, electric heater 6 places in the housing 4, housing 4 bottoms are covered by base (5,9) and are the sealing shape.

As Fig. 1, shown in Figure 2, lid (1,2,3) by lid handle 1, handle connector 2, lid body 3 is assembled, lid body 3 is made of double-deck interlayer (inwall 30 and outer wall 31), the bottom is provided with the rim of projection, the cavity that is sealed to form between lid inwall 30 and the outer wall 31, be pumped into vacuum or with heat-barrier material fillings such as polyurethanes, outer wall 31 tops have connecting hole, be connected with handle connector 2, handle connector 2 is connected with lid handle 1 in addition, and will cover handle 1 and be fixed on outer wall 31 tops, housing 4 is the waist drum shape, also constitute by double-deck interlayer (inner and outer wall), the cavity that is sealed to form between inner walls 40 and the outer wall 41 also is pumped into vacuum or with heat-barrier material fillings such as poly-peace fat, the rim of housing 4 tops and lid (1,2,3) coincide and joins, electric heater 6 is placed in the intracavity bottom of housing 4, the outside is filled up thermal insulation board 7 again, then base plate 8 is contained in housing bottom, and closes with housing 4 and to combine, base plate 8 also can be made the plate body that two-layer interlayer (inwall 80 and outer wall 81) constitutes, also can be pumped into vacuum between plate inner wall 80 and the outer wall 81 or with heat-barrier material fillings such as polyurethanes, base plate (80,81) also can be one-body molded with housing 4.During use, the housing 4 that electric heater 6 is housed is placed on the base (5,9), base (5,9) is made of face-piece 5 and drain pan 9.

As shown in Figure 3, Figure 4, lid inwall (30), inner walls (40), plate inner wall (80) inner surface are coated with radiation proof aluminium film 10.
