Abstract
The utility model relates to an electric water heater using both the electric energy and hot fluid as hot source with convenient assembly and maintenance, which comprises an inner bag, an electric heating tube, a temperature controller, a water inlet pipe and a water outlet pipe and is characterized in that the electric heating tube is positioned on a mounting plate sealed at an opening of the inner bag, a heat exchange water pipe is fixedly arranged on the mounting plate and the inlet and outlet of the heat exchange water pipe are disposed outside the mounting plate. The electric heating tube and the heat exchange water pipe for the heat exchange of the hot fluid and the cold water in the inner bag are positioned on the mounting plate, so that only the mounting plate needs to be disassembled from the inner bag for maintaining the electric heating tube and the heat exchange water pipe, without putting off the whole inner bag. The maintenance is very convenient.
Description
Technical field
The utility model relates to a kind of electric heater, particularly a kind of have simultaneously can electrification heating and utilize hot water to make the electric heater of hot water in the thermal source heating inner bag.
Background technology
Existing electric heater comprises inner bag, electrothermal tube, temperature controller and inlet tube and outlet tube, wherein electrothermal tube is used to heat the cold water in the inner bag, inlet tube and outlet tube is used for supplying cold water and drawing hot water to inner bag respectively, the shortcoming of this electric heater is to use electric energy that the water in the inner bag is heated, and can not realize the heating of multipotency source side formula.
Summary of the invention
The purpose of this utility model is the single problem of heat source way that exists in the existing electric heater in order to solve, and provides a kind of electric energy that both can use also can use hot fluid to make thermal source, and installation and maintenance electric heater easily.
The purpose of this utility model is achieved in that a kind of electric heater, comprise inner bag, electrothermal tube, temperature controller and inlet tube and outlet tube, fix described electrothermal tube on the installing plate that it is characterized in that matching, on this installing plate, also be fixed with the heat exchange water pipe that import and export all is positioned at the installing plate outside with the sealing of the opening part of described inner bag.Because electrothermal tube and be used for hot fluid and heat exchange water pipe that inner bag cold water carries out heat exchange is installed in installing plate, when maintenance electrothermal tube or heat exchange water pipe, only need unload installing plate and get final product from inner bag, and do not need whole inner bag is taken down, and the maintenance utmost point is convenient.
Described electric heater is characterized in that also being fixed with on the described installing plate blind pipe.This blind pipe is used to install thermostat probe.
Owing to adopted technical scheme described in the utility model, having at some can be with the place of hot fluid as thermal source, this electric heater need not use power supply, and the import that only needs hot fluid to be introduced the heat exchange water pipe gets final product, many thermal source heating have been realized, particularly concerning the user who lives in north band central heating, these users can directly use the hot water of central heating as thermal source, the hot water that is about to central heating is introduced in the heat exchange water pipe of electric heater, and the cold water in the inner bag is heated; And, because electrothermal tube and be used for hot fluid and heat exchange water pipe that inner bag cold water carries out heat exchange is installed in installing plate, when maintenance electrothermal tube or heat exchange water pipe, only need installing plate unloaded from inner bag and get final product, and do not need whole inner bag is taken down, the maintenance utmost point is convenient.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
It shown in the accompanying drawing cut-away view of an embodiment of electric heater described in the utility model.
Among the figure 1, inner bag, 12, outlet pipe, 3, installing plate, 5, blind pipe, 4, electrothermal tube, 11, water inlet pipe.
The specific embodiment:
See shown in the accompanying drawing, described electric heater, comprise inner bag 1, electrothermal tube 4, temperature controller (not drawing among the figure) and water inlet pipe 11, outlet pipe 12, electrothermal tube 4, blind pipe 5 and heat exchange water pipe 6 all are fixed on the installing plate 3, the probe of unillustrated temperature controller stretches in the blind pipe 5, the import and export of heat exchange water pipe 6 all is positioned at installing plate 3 outsides, sealing between installing plate 3 and the inner bag 1, and its principle is the same with existing electric heater when using the water heating in 4 pairs of inner bags of electrothermal tube 1; And when using the hot fluid heating, only need hot fluid (as the hot water of central heating) is introduced the heat exchange water pipe 6 of flowing through, tube wall and cold water inner bag in of the heat that makes hot fluid by the heat exchange water pipe carries out heat exchange and gets final product.
When maintenance electrothermal tube or heat exchange water pipe, installing plate 3 is unloaded from inner bag get final product earlier.
Claims (2)
1. electric heater, comprise inner bag, electrothermal tube, temperature controller and inlet tube and outlet tube, fix described electrothermal tube on the installing plate that it is characterized in that matching, on this installing plate, also be fixed with the heat exchange water pipe that import and export all is positioned at the installing plate outside with the sealing of the opening part of described inner bag.
2. according to the described electric heater of claim 1, it is characterized in that also being fixed with on the described installing plate blind pipe.
