Abstract
The utility model relates to a water storage type electric water heater. It includes inner bag, heating member, heat preservation and shell, the metal heat conductor and the electric heating tube of heating member package rubbing board form, electric heating tube is wrapped up by the metal heat conductor, and the heating member is installed at outer surface of liner, and the heating member surface is equipped with the insulating layer, and the heat preservation is established at the insulating layer surface, shell parcel heat preservation. The utility model discloses structural design is simple equitable, electric heating tube through the casting in aluminum product or iron material, electric heating tube is not fragile, and is durable, the whole cast comes out, the heating area of heating member can accurately calculate, then according to the power of water heater can be fine the heating member power that sets up unit area, the temperature is controlled well, and is safe in utilization.
Description
Technical field
This utility model relates to a kind of water-storage electric heater.
Background technology
The calandria of existing water-storage electric heater is typically all located in inner lining, easily leaks electricity, and easy fouling of electric heating tube etc., weak point is a lot.The most also occur calandria to be arranged on outside inner lining, as heating wire is wrapped in outer surface of liner, find after using, heats is not all right, dangerous. and also having and film like software heater is located at outer surface of liner, anti-dry etc. is wayward, the most dangerous, cost is the highest.
Summary of the invention
Therefore, the purpose of this utility model is to provide that a kind of heating surface (area) (HS is big, processing is simple, the water-storage electric heater of easy temperature control.
The purpose of this utility model is realized in.
A kind of water-storage electric heater, including inner bag, calandria, heat-insulation layer and shell, described calandria includes metal heat conducting-body and the electric heating tube of tabular, electric heating tube is wrapped up by metal heat conducting-body, calandria is arranged on outer surface of liner, calandria outer surface is provided with thermal insulation layer, and heat-insulation layer is located at thermal insulation layer outer surface, shell parcel heat-insulation layer.
This utility model structure design advantages of simple, electric heating tube is by being cast in aluminium or ferrous material, electric heating tube is hardly damaged, durable, out, the heating area of calandria can accurately calculate in one piece casting, then can well the calandria power of setting unit area according to the power of water heater, temperature controls well, uses safety.
Accompanying drawing explanation
Fig. 1 is embodiment schematic cross-sectional view.
Fig. 2 is calandria exterior surface appearance schematic diagram.
Fig. 3 is calandria inner surface schematic appearance.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Embodiment, in conjunction with Fig. 1 to Fig. 3, a kind of water-storage electric heater, including inner bag 1, calandria 2, heat-insulation layer 3 and shell 4, described calandria 2 includes the metal heat conducting-body 5 of tabular and two groups of electric heating tubes 6, and two groups of electric heating tubes 6 are all wrapped up by metal heat conducting-body 5, calandria 2 is arranged on inner bag 1 outer surface, calandria 2 outer surface is provided with thermal insulation layer 7, and heat-insulation layer 3 is located at thermal insulation layer 7 outer surface, and shell 4 wraps up heat-insulation layer 3.Owing to metal heat-conducting body surface area calculates well, therefore heating surface (area) (HS controls well, all right control of power that per unit heating surface is long-pending.Electric heating tube uses the most highly developed electric heating tube, and electric heating tube is the most highly developed in insulating square surface technology, and electric heating tube is located at again outer surface of liner, and water power is kept completely separate, safety.
