Abstract
An electric water heater comprises an outer shell, a water tank, a water inlet pipe, a water outlet pipe, and an electric water heater with an electric heater inside. The electric water heater is characterized in that a heat exchanger is arranged on the upper portion in the water tank, one end of the heat exchanger is communicated with the water inlet pipe, the other end is communicated with the water outlet pipe, an atmosphere communication pipe which is communicated with environment is further arranged in the water tank, a water feeding branch pipe is connected on the water inlet pipe, a water level sensing controller is arranged on the upper end portion of the water feeding branch pipe, the water level sensing controller controls a magnetic valve arranged on the lower end of the water feeding branch pipe, and the heat exchanger is composed of heat conducting pipelines with enough water path length.
Description
Technical field
The utility model relates to electric heater, is specifically related to a kind of domestic, electric water heater.
Background technology
In the existing electric heater, storage water heater more commonly, open-type water heater is owing to being subjected to structural limitations, and market demand is very limited.With present technical merit, there is an insoluble problem in the storage water heater, is exactly the seepy question of inner bag, though inner bag is being updated, owing to its specific working environment, makes it be difficult to reach people's expected service life.
Summary of the invention
For solving the above-mentioned deficiency of prior art, the purpose of this utility model provides a kind of electric water heater, can solve the inner bag seepy question.
For achieving the above object, technical solution of the present utility model is: comprise the electric heater of shell, water tank, water inlet pipe and water outlet pipe, electric heater, it is characterized in that, be provided with heat exchanger at the water tank internal upper part, one end of heat exchanger is communicated with water inlet pipe, and the other end is communicated with outlet pipe; In water tank, also be provided with one with the atmospheric communicating pipe of external communications; Be connected to water arm on the water inlet pipe, the upper end of water arm is provided with the level sensor controller on this, is located at the magnetic valve of water arm lower end by this level sensor controller control; Described heat exchanger is made of the heat conduction pipeline of enough water routes path.
As shown from the above technical solution, electric heater of the present utility model because water tank can not be subjected to very big pressure, is just worked under normal pressure, therefore, can reach desirable service life, has thoroughly solved the life problems of water heater liner.
Description of drawings
Accompanying drawing is a kind of structural representation of the utility model embodiment
(1) is that water inlet pipe (11) is that upward water arm (2) is that hot water outlet pipe (3) is that atmospheric communicating pipe (4) is that level sensor controller (5) is that magnetic valve (6) is that water tank (7) is that heat exchanger (8) is that shell (9) is a heat-insulation layer among the figure
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Accompanying drawing is the structural representation of a kind of embodiment of the utility model, in the present embodiment, heat exchanger (7) is positioned at water tank (6) top, its two ends are communicated with water inlet pipe (1) and outlet pipe (2) respectively, atmospheric communicating pipe (3) makes water tank inside and outside atmosphere keep being communicated with, on water inlet pipe (1), also be provided with into water arm (11), upper end at water inlet arm (11) is provided with level sensor controller (4), be located at the into magnetic valve of water arm lower end (5) work by the control of level sensor controller, to guarantee that the water level in the water tank is in normal water level, its height of water level is lower than the height of atmospheric communicating pipe (3), is provided with heat-insulation layer (9) between water tank (6) and the shell (8).In the present embodiment, heat exchanger system is made of the copper pipe of sufficient length.
Working method of the present utility model is, level sensor controller control magnetic valve injects certain water in water tank, its height of water level is lower than the height of atmospheric communicating pipe, is higher than the height of heat exchanger, utilizes electric heater that the water in the water tank is heated to uniform temperature then.During use, when cold water passes through heat exchanger, absorb the heat of water storage in the water tank, promote temperature, finish heat exchange, and from outlet pipe, flow out, for using.
Claims (3)
1. electric heater, comprise shell, water tank, water inlet pipe and water outlet pipe, atmospheric communicating pipe, heat exchanger, it is characterized in that: the top in water tank is provided with heat exchanger, one end of heat exchanger is communicated with water inlet pipe, the other end is communicated with outlet pipe, also is provided with one and leads to atmosphere outside communicating pipe in water tank.
2. electric heater according to claim 1, it is characterized in that: be connected with water arm on the water inlet pipe, be provided with the level sensor controller in the upper end of last water arm, be provided with magnetic valve, control this magnetic valve work by the level sensor controller in the lower end of last water arm.
