Abstract
The utility model provides an internal lining structure for an electric water heater, which belongs to the technical field of a water heater and is designed in order to reduce wastage, brings convenience to the replacement of the electric heating components and enable the container of the electric water heater to be used again. The internal lining structure comprises a container 1 comprising a water inlet 11 and a water outlet 12. An electric heating component is fixedly connected with a container 1, and the electric heating tube 21 of the electric heating component is arranged inside the container, and a connector 22 thereof is arranged outside the container. The internal lining structure is characterized in that one end of the container 1 is open, and the end of the container is fixedly connected with a flange 19; a threaded connecting piece fastens the flange 19 and the terminal board 29 of the electric heating component. In addition, a sealer is arranged between the terminal board 29 and the flange 19.
Description
Technical field
The utility model belongs to technical field of water heaters, relates in particular to the inner bag of electric heater.
Background technology
The inner bag of electric heater comprises a container that contains water inlet and delivery port, have electrothermal device and container to install and the electrothermal tube of electrothermal device be positioned at container simultaneously its binding post outside container.On existing product, by welding electrothermal device is packed on the container, so be difficult to dismounting; After electrothermal device damaged, the inner bag of whole electric heater can be formed waste by integral replacing.
Summary of the invention
The purpose of this utility model provides a kind of inner-tube structure that can be convenient for changing the electric heater of electrothermal device, makes the container of inner container of electric water heater can continue to continue to employ, thereby reaches the purpose of saving resource and work.
The technical solution of the utility model is: between the wiring end plate of electrothermal device and container joint, acquire sealing gasket, and with threaded connector locking, sealed wiring end plate and container joint.That is:
A kind of inner-tube structure of electric heater comprises a container that contains water inlet and delivery port, has electrothermal device and container to install, and the electrothermal tube of electrothermal device is positioned at its binding post of container while outside container; It is characterized in that: an end of described container is opened wide and its end is fixed with flange, has threaded connector to lock the wiring end plate of this flange and electrothermal device, and has the sealing gasket pad to put between wiring end plate and flange.
The beneficial effects of the utility model: by said structure as can be known, in needs, can change electrothermal device of the present utility model and continue simultaneously to continue to employ its container, thereby reach the purpose of saving resource and work.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the master under the embodiment decomposing state looks schematic diagram.
Fig. 2 is the schematic perspective view under the embodiment decomposing state.
Fig. 3 is the schematic diagram of electrothermal device.
The specific embodiment
As shown in the figure, a kind of inner-tube structure of electric heater comprises a container 1 that contains water inlet 11 and delivery port 12, has electrothermal device 2 and container 1 to install, and the electrothermal tube 21 of electrothermal device is positioned at its binding post 22 of container while outside container; It is characterized in that: an end of container 1 is opened wide and its end is fixed with flange 19, and the wiring end plate 29 of threaded connector locking flange 19 and electrothermal device is arranged, and has sealing gasket 3 pads to put between wiring end plate 29 and flange 19.
As shown in the figure, the basic structure of container 1 is the cylindrical shell that its upper end closed, a lower end open wide and have in the bottom flange; Water inlet pipe 110 continues at the sidewall of cylindrical shell near lower end part; Outlet pipe 120 continues at the sidewall (as shown) of cylindrical shell near the position, upper end; In addition, outlet pipe 120 also can continue at the upper end face part of container.
As shown in the figure, electrothermal device 2 comprises a wiring end plate 29; Electrothermal tube 21 and binding post 22 are distributed in the both sides of wiring end plate 29, and the heating wire in binding post 22 and the electrothermal tube 21 is connected with electric conductor.
As shown in the figure, (whole four) electrothermal tube 21 can be divided into two groups, and wherein the space configuration of one group of electrothermal tube (being illustrated as) is U-shaped, space configuration of another group electrothermal tube (being illustrated as three) approximate " the vertical section profile of flask "; On spatial arrangement, the installed surface of two groups of electrothermal tubes is vertical mutually, and one group of electrothermal tube is surrounded by another group electrothermal tube.This structure make the heating position of electrothermal device 2 more concentrate on its position away from wiring end plate 29, relatively near the water outlet position, the leaving water temperature that helps the maintaining heat hydrophone is at optimum range.
In addition, for the heating position that makes electrothermal tube 21 rationally distributes, two kinds of different heating wire have been adopted in the electrothermal tube inside of embodiment, and its resistivity near the unit length of the heating wire of wiring end plate 29 is lower.
