Abstract

The utility model relates to the electric water heater technology field, providing an electric water heater having warm air function, comprising a casing, an electric water heater and a power supply and control circuit. The casing is divided into a heating chamber and an electronic apparatus chamber by a separator. A pipe heater is placed in the heating chamber. On an edge of the heating chamber, a wind inlet and a wind outlet are arranged and are mounted and electrically connected with a radiator fan. The pipe heater is a multi-pipe structure. At least one pipe is provided to place a heating unit. At least one pipe is used as a fluid passage pipe. The heating pipe can be a multi-pipe structure and more than one heating units are mounted on each pipe. The advantages of the utility model are that: (1) the pipe heater is not only a heater of the water heater, but also a heating unit of a warm air heater. Only a radiator fan is added in the electric water heater, which realizes the warm air function. A tractor serves several purposes and parts, mounting wirings and space are saved; (2) the utility model improves utilization ratio of the heater of the electric water heater; (3) in process that the heater is used or after the heater is used, heat air in the unit is dropped away in time, which protects the electric element and prolongs the use life.

Description

Electric heater with warm braw function

Technical field

The utility model relates to the electric heater technical field.

Background technology

In the prior art, the shower heating of house adopts warm-air drier or heater more, because high humidity in the bathroom, heating system damages easily, and takies bathroom space, installs and uses inconvenience, and existing electric heater only provides water heating function, function singleness.

The utility model content

The purpose of this utility model is a kind of electric heater with warm braw function of design, and it has water heater function and warm-air drier function, and dual-use is simple in structure.

The utility model can be realized by following approach:

Electric heater with warm braw function, include housing, electric heater, power supply and control circuit, it is characterized in that: the housing inner-use clapboard is divided into two chambers, one is heating clamber, one is electric apparatus room, settles tube heater in the heating clamber, and the heating clamber limit is provided with air inlet and air outlet, install near the air outlet in the heating clamber and and be electrically connected a radiator fan, place electric elements in the electric apparatus room.

Air outlet and air inlet are located at the below and the top of heating clamber respectively.

The scheme of optimizing is that the air inlet of heating clamber is located at dividing plate by the upper end, and this air inlet is communicated with heating clamber and electric apparatus room, and the electric apparatus room limit is provided with second air inlet.

Further design is that described tube heater includes heat exchange body and heater, the heat exchange body is disjunctor multitube structure side by side, with the good material manufacturing of heat conductivility, wherein at least one pipe is as the heating tube of placing heater, at least one pipe is as fluid channel tube, and pipe joint is established at the two ends of fluid channel tube.

As optimization, described heating tube can be multi-segment structure, and installs more than 1 heater at each section.

Aspect the circuit design scheme, tube heater is the heater of water heater, is again the heater of warm-air drier,

During as the instant electric water heater, open user's tap, current are passed through in heater, connect all or part of heater simultaneously, be heated through the fluid in the heater, radiator fan starts simultaneously, and the heat on heater and electric elements surface is left.

During as warm-air drier, start radiator fan, connect all or part of heater that is positioned at the heater side simultaneously, because the heater inner fluid does not flow, heter temperature improves rapidly, and room air is heated by convection type through the heater outside in the effect current downflow of radiator fan.

Be compared with the prior art, the utlity model has following characteristics and progress:

1. only in electric heater, increase a radiator fan and promptly realize the warm-air drier function, save parts, save wiring and space are installed.

2. improved the utilization rate of electric heater heater.

3. water heater uses in back or the use, can as early as possible the hot-gas drive in the machine be gone, and to the protection electric elements, it is helpful to increase the service life.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a K-K face cutaway view among Fig. 1.

The specific embodiment

Embodiment one

With reference to figure 1, the utility model proposes a kind of electric heater with warm braw function, it includes housing 5, electric heater 10, power supply and control circuit 6, it is characterized in that: housing 5 inner-use clapboards 7 are divided into two chambers, and one is heating chamber A, and one is electric apparatus room B, settle tube heater 10 in the heating chamber A, the heating chamber A limit is provided with air inlet A1 and air outlet A2, install near the air outlet A2 in the heating chamber A and and be electrically connected a radiator fan 4, place electric elements in the electric apparatus room B.

Air outlet A2 in the present embodiment and air inlet A1 are located at the below and the top of heating clamber respectively.

Aspect the circuit design scheme, tube heater 10 is the heater of water heater, is again the heater of warm-air drier,

During as the instant electric water heater, connect all or part of heater when current pass through in the heater 10, be heated through the fluids in the heater 10, radiator fan 4 starts simultaneously, and the heat on heater 10 surfaces is left.

During as warm-air drier, start radiator fan, connect all or part of heater that is positioned at heater 10 sides simultaneously, heater 10 temperature improve rapidly, and room air is heated with convection type through heater 10 outsides in the effect current downflow of radiator fan 4.

Embodiment two

Again with reference to figure 1, be that the air inlet of heating chamber A is located at the B2 place of dividing plate 7 by the upper end to the prioritization scheme of embodiment one, this air inlet B2 is with heating clamber and electric apparatus room connection, and electric apparatus room B side is provided with air inlet B1.
