Description

A kind of instant electric water heater

Technical field

The utility model relates to electric heater technical field, specially a kind of instant electric water heater.

Background technique

Electric heater refers to the water heater heated using electricity as the energy.It is and gas heater, solar water heater One of big water heater of mutually arranged side by side three.Electric heater can be divided into storage-type (also known as positive displacement or heat accumulation by heating power size Formula), three kinds of instant heating type, fast heating type (also known as half storage-type).

Although common quick-heating electric water heater and double-mode electric water heater volume are similar, internal structure is far from each other, Quick-heating electric water heater and storage-type electric water heater are more powerful than being only small volume, so in heating speed really Faster than storage-type electric water heater, but it is in spring, autumn cannot all reach i.e. hot, also to preheat, that is, need to wait, and bimodulus Electric heater is in spring, summer, three seasons of autumn available i.e. heat pattern, instant-heating.

But there are some drawbacks in use in traditional instant electric water heater, such as:

Traditional instant electric water heater directly heats cooler chilled water flow, therefore is easy when heating So that the temperature of electric heater is slowly difficult to rise, it is easy to make the power increase of electric heater, electric heater is caused to be easily damaged, it is both unfavorable In energy conservation, it is also easy to lead to equipment damage.

Utility model content

The purpose of this utility model is to provide a kind of instant electric water heaters, mentioned above in the background art to solve Problem.

To achieve the above object, the utility model provides the following technical solutions: a kind of instant electric water heater, including electric heating Pipe fixing seat, screw shell, return pipe and electrothermal tube, fixing sleeve is connected to electrothermal tube seat respectively at the screw shell both ends, described Electrothermal tube is fixedly installed between electric heating tube socket, the electrothermal tube is fixed inside screw shell, and the electric heating tube socket is remote Fixed from electrothermal tube side to be connected with binding post, the binding post and electrothermal tube are electrically connected, and the binding post is far from electrothermal tube Seat threaded one end is equipped with wiring nut；

The screw shell one end side is fixedly welded with water inlet pipe, and the water inlet pipe is far from the fixed weldering in screw shell one end It is connected to water inlet connection, screw shell other end side is fixedly welded with outlet pipe, and the outlet pipe is far from screw shell One end is fixedly welded with water outlet joint, and the water inlet pipe and outlet pipe side are welded with return pipe jointly, in the outlet pipe Portion is fixedly welded with weather board.

Further, the wiring nut is manufactured using insulating materials.
