Abstract
The utility model discloses a heating device of an electric water heater, which comprises an electric heating pipe and a water container. The electric heating pipe is bent to be M-shaped or W-shaped, the water container is a metal pipe wound around an outer surface of the electric heating pipe, and two ends of the water container are respectively provided with a water inlet and a water outlet. The heating device has the advantages of fine heat conducting performance, safe utilization and relatively high heating efficiency.
Description
Technical field
The utility model relates to a kind of heating apparatus of electric water heater, particularly a kind of heating apparatus of electric water heater of Instant heating type and quick-heating type.
Background technology
Along with the development of society and improving constantly of people's living standard, electric heater substitutes the main flow that gas heater becomes water heater just gradually.Existing heating apparatus of electric water heater is made up of electric heating tube and water receptacle mostly, and electric heating tube is placed in the water of water receptacle and heats, and surface and water by electric heating tube carry out heat exchange, thereby realize the heating of water.The defective that this structure exists is: heating apparatus of electric water heater in use electric heating tube adheres to incrustation scale easily, can cause heat-conductive characteristic to descend after having used of a specified duration, even the phenomenon that electric heating tube breaks can take place, the potential safety hazard that has electric leakage simultaneously, heat exchange area is less in addition, and the thermal efficiency is lower.
The utility model content
The purpose of this utility model provides a kind of heating apparatus of electric water heater, has good heat-conductive characteristic, and is safe in utilization and the thermal efficiency is higher.
For achieving the above object, the technical solution of the utility model is:
A kind of heating apparatus of electric water heater comprises electric heating tube and water receptacle, it is characterized in that:
Described electric heating tube bends to M shape or W shape,
Described water receptacle is the metal tube that is spirally wound on the electric heating tube outer surface,
The two ends of described water receptacle are respectively water inlet and delivery port.
As improvement, be filled with heat-conducting metal between electric heating tube described in the utility model and the water receptacle.
The utility model can be done further improvement, and described heat-conducting metal is a metallic aluminium.
Therefore compared with prior art, the utility model has following beneficial effect:
(1) electric heating tube separates with water receptacle in the utility model, so both can avoid fully forming incrustation scale on the surface of electric heating tube, therefore have good heat-conductive characteristic, also can avoid water directly to contact fully and the leaky that produces, use as safe as a house with electric heating tube;
(2) adopt the electric heating tube of M shape or W shape can increase heat transfer area in the utility model, prolong water in the heat time heating time of the thermal treatment zone, make thermal energy to be fully used, the thermal efficiency is higher.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Fig. 1 is the schematic diagram of the utility model embodiment;
Fig. 2 is the cut-away view of the utility model embodiment;
Fig. 3 be among Fig. 1 A-A to cutaway view;
Fig. 4 be among Fig. 1 B-B to cutaway view.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Be the embodiment of a kind of heating apparatus of electric water heater described in the utility model as shown in Figures 1 to 4, comprise electric heating tube 1 and water receptacle 2, electric heating tube 1 bends to M shape or W shape, water receptacle 2 is the metal tube that is spirally wound on the outer surface of electric heating tube 1, and the two ends of water receptacle 2 are respectively water inlet 21 and delivery port 22.
During actual the use, water is heated by electric heating tube 1 in the water receptacle 2 of flowing through, since the moisture in electric heating tube 1 and water receptacle 2 and the water receptacle 2 from, both can avoid fully forming incrustation scale on the surface of electric heating tube 1, has good heat-conductive characteristic, the leaky that can avoid water directly to contact with electric heating tube 1 again fully and produce is used as safe as a house.On the other hand, because electric heating tube 1 is M shape or W shape, so heat transfer area is bigger, heat more evenly, the utilization of heat energy is more abundant, helps the thermal efficiency of energy savings and the whole electric heater 1 of raising.
In order to improve the uniformity that adds thermal effect and guarantee to heat of 1 pair of water receptacle 2 of electric heating tube, can fill heat-conducting metal 3 between electric heating tube 1 and the water receptacle 2, in the present embodiment, heat-conducting metal 3 is a heat conductivility good metal aluminium.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
Claims (3)
1. a heating apparatus of electric water heater comprises electric heating tube and water receptacle, it is characterized in that:
