Abstract

The utility model relates to an electrothermal film type electric boiler for heating water, a heat preservation sandwich layer 2 is inlaid between a housing 1 and a water contain cavity body 3, wherein, the water contain cavity body is composed of a steel plate inner container 6, an insulating layer 8, and an electrothermal film 9; the inner and the outer surfaces of the steel plate inner container are sintered with glass enamel layers 7, the insulating layer is solidified on the outer surface of the steel plate inner container, the electrothermal film which adopts a one-way heating structure is fixed on the outer surface of the insulating layer, and a heat-generating surface is fixedly arranged on the insulating layer. The utility model has the advantages of high thermal efficiency, long service life, good reliability and safety, small size, and less water consumption.

Description

Electrothermal membrane type electrical heating water boiler stove

The utility model belongs to the improvement of electrical heating water boiler stove.

Existing electrical heating water boiler stove generally all adopts electrothermal tube as heating element heater, and it has the thermal efficiency and service life is low, the shortcoming of reliability and safe differential.

The purpose of this utility model is a kind of electrothermal membrane type electrical heating water boiler stove of development, and this boiler has the good characteristics of thermal efficiency height, long service life, reliability and security.

The utility model comprises housing 1, insulation interlayer 2, water containing chamber body 3, water inlet pipe 4, outlet pipe 5, insulation interlayer 2 is set between housing 1 and the water containing chamber body 3, water inlet pipe 4 is fixed on the bottom of housing 1, and be connected with the bottom of water containing chamber body 3, outlet pipe 5 is fixed on the top of housing 1, and is connected with the top of water containing chamber body 3.Water containing chamber body 3 is made up of steel plate inner bag 6, insulating barrier 8, Electric radiant Heating Film 9.Sintering has glass enamel layer 7 on the surfaces externally and internally of steel plate inner bag 6, and insulating barrier 8 is solidificated on the outer surface of steel plate inner bag 6, and Electric radiant Heating Film 9 is fixed on the outer surface of insulating barrier 8, and Electric radiant Heating Film 9 adopts unidirectional heat radiating structure, and heating face is affixed on the insulating barrier 8.

The utility model has adopted the Electric radiant Heating Film of unidirectional heating to make heater element, so the flames of anger, odorlessness, the thermal efficiency can reach 98%, because the optimization of water containing chamber body structure, its conduction heat and radiant heat energy are fully absorbed by water, economize on electricity more than 30% than common electrical heat pipe, heating wire, working life can reach 100,000 hours, is 50-100 times of other heating.Also because steel plate glass enamel inner bag non-scaling, easy cleaning, corrosion-resistant improve the water containing chamber body life time, again since water in water containing chamber, electrical heating elements makes water power not contact outside water containing chamber, makes its security better.It also has advantages such as volume is little, water consumption is little, the interior water circulation of oblate box body heating chamber heating is effective.

Fig. 1 is an overall structure schematic diagram of the present utility model, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the structural representation of embodiment four.

Embodiment one: present embodiment is made up of housing 1, insulation interlayer 2, water containing chamber body 3, water inlet pipe 4, outlet pipe 5, insulation interlayer 2 is set between housing 1 and the water containing chamber body 3, water inlet pipe 4 is fixed on the bottom of housing 1, and be connected with the bottom of water containing chamber body 3, outlet pipe 5 is fixed on the top of housing 1, and is connected with the top of water containing chamber body 3.Water containing chamber body 3 is made up of steel plate inner bag 6, insulating barrier 8, Electric radiant Heating Film 9.Sintering has glass enamel layer 7 on the surfaces externally and internally of steel plate inner bag 6, and insulating barrier 8 is solidificated on the outer surface of steel plate inner bag 6, and Electric radiant Heating Film 9 is fixed on the outer surface of insulating barrier 8, and Electric radiant Heating Film 9 adopts unidirectional heat radiating structure, and heating face is affixed on the insulating barrier 8.

Embodiment two: present embodiment is made oblate box body for improving the thermal efficiency with steel plate inner bag 6, and the heating face of two Electric radiant Heating Film 9 is affixed on the insulating barrier 8 of round box body front-back 10,11 opposite to each other.Other composition is identical with embodiment one with annexation.

Embodiment three: present embodiment is added with temperature probe 12 on Electric radiant Heating Film 9, and temperature probe 12 is connected with temperature controller 13, gives when putting temperature when water is heated to, and temperature controller 13 can cut off the power supply automatically, is lower than to give when putting temperature temperature controller 13 and can switch on automatically again.

Embodiment four: for strengthening heating power and speed, adopt a plurality of water containing chamber bodies 3 to be composed in series large power, electrically hot diaphragm type electrical heating water boiler stove in housing 1.
