Abstract

The utility model discloses an electric water heater, which comprises an outer housing, a water inlet pipe, and a water outlet pipe. The electric water heater has the characteristics that three inner containers mutually communicated at two ends through a communicating pipe are mounted up and down in rows in the outer housing, one end of the upper inner container is connected with the water inlet pipe, an electrothermal tube is mounted in the lower inner container, one end of the middle inner container is connected with the water outlet pipe and the temperature controlled sensor, and a vacuum structure is formed between the inner container and the outer housing. The electric water heater tackles the problems of the prior electric water heater that the heat efficiency is low and the insulating effect is weak, and suits the installation and use in the places such as family, guesthouse, and the like.

Description

Electric heater

Technical field

The utility model relates to field of household appliances, a kind of specifically utensil that utilizes electrical heating to heat up water.

Background technology

At present, mostly the electric heater that uses in the society is to adopt the simple structure that heating tube is installed in the inner bag, and its shortcoming is that the thermal efficiency is low, heat insulation effect is poor.

Summary of the invention

The present electric heater thermal efficiency is low, the problem of heat insulation effect difference in order to solve for the utility model, invents a kind of electric heater of many inner bags vacuum structure.

The technical solution of the utility model is, a kind of electric heater, comprise shell, water inlet pipe, outlet pipe, its special character is: row is adorning the inner bag that three two ends are communicated with by communicating pipe mutually up and down in the enclosure, one end of upper inner-liner connects water inlet pipe, electrothermal tube is housed in the bottom inner container, and an end of middle inner bag connects outlet pipe, temperature control sensor, leaves vacuum structure between inner bag and the shell.On the sidewall of shell vacuum tube is housed, temperature detect switch (TDS), hot and cold water switching valve are housed on the front of shell.

During use, earlier inner bag is filled with water by water inlet pipe, connecting power supply is again heated by the electrothermal tube in the bottom inner container, when reaching the water temperature of setting, temperature control sensor can be controlled the temperature detect switch (TDS) outage automatically, can hot water be emitted use by the outlet pipe of bottom inner container one end then, can regulate by the hot and cold water switching valve if water temperature is too high; Vacuum tube on the side wall of outer shell is specialized in when making, with the air sucking-off between shell and the inner bag.

Technique effect of the present utility model is, adopts above-mentioned technical scheme, can realize a kind of suitable energy-conservationly more than 60%, and insulation is at the electric heater more than 20 hours.

Description of drawings

Fig. 1 is a structural front view of the present utility model, and the accompanying drawing that makes an abstract.

Fig. 2 is an external view of the present utility model.

In the drawings, 1 water inlet pipe, 2 outlet pipes, 3 temperature control sensors, 4 electrothermal tubes, 5 shells, 6 communicating pipes, 7 inner bags, 8 hot and cold water switching valves, 9 temperature detect switch (TDS)s, 10 vacuum tubes.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further specified.

As shown in the figure, row is adorning the inner bag 7 that three two ends are communicated with by communicating pipe 6 mutually up and down in shell 5, and an end of upper inner-liner 7 connects water inlet pipe 1, and electrothermal tube 4 is housed in the bottom inner container 7, one end of middle inner bag 7 connects outlet pipe 2, temperature control sensor 3, leaves vacuum structure between inner bag 7 and the shell 5.Vacuum tube 10 is housed on the sidewall of shell 5, temperature detect switch (TDS) 9, hot and cold water switching valve 8 are housed on the front of shell 5.

During use, earlier inner bag 7 is filled with water by water inlet pipe 1, connect power supply again by 4 heating of the electrothermal tube in the bottom inner container 7, when reaching the water temperature of setting, temperature control sensor 3 can be controlled temperature detect switch (TDS) 9 outages automatically, outlet pipe 2 that then can be by bottom inner container 7 one ends is emitted use with hot water, can regulate by hot and cold water switching valve 8 if water temperature is too high; Vacuum tube 10 on shell 5 sidewalls is specialized in when making, with the air sucking-off between shell 5 and the inner bag 7.

Claims

1. electric heater, comprise shell, water inlet pipe, outlet pipe, it is characterized in that: row is adorning the inner bag that three two ends are communicated with by communicating pipe mutually up and down in the enclosure, one end of upper inner-liner connects water inlet pipe, electrothermal tube is housed in the bottom inner container, one end of middle inner bag connects outlet pipe, temperature control sensor, leaves vacuum structure between inner bag and the shell.
