Abstract

The utility model discloses a heating device for electric water heaters, which is characterized in that a plurality of external spiral rewinding rings of a high efficiency heat source pipe (2) are provided with heating ducts (3); the design of spiral rewinding increases the contact area of the high efficiency heat source pipe (2) and the heating ducts (3), prolongs the flow time of water which flows through the heating ducts (3), and makes the discharging water have an equivalent temperature; one ends of the heating ducts (3) are water inlets (31), and the other ends of the heating ducts (3) are water outlets (32); the outer sides of the high efficiency heat source pipe (2) and heating ducts (3) are provided with insulating outer covers (4), so the utility model has the advantages of centralized heat covering, high heating efficiency, and electricity saving.

Description

A kind of heater of electric heater

The utility model relates to the household electrical appliance class, particularly a kind of heater of electric heater.

As Fig. 4, shown in Figure 5, the heater of general common electric heater includes the water tank (5) and a traditional type Heat source device (6) of a ccontaining water, be provided with a water inlet (51) in water tank (5) top, be provided with delivery port (52) in water tank (5) below, and establish a traditional type Heat source device (6) from water tank (5) top opening (53) group, during use, cold water is imported in the water tank (5) by water inlet (51), heat via Heat source device (6), water after temperature improves is flowed out by delivery port (52), for use, its shortcoming is as follows:

(1), when it is used for general small electrical water heater, its warm current must be continuously to provide, and therefore, if be heated at short notice after desiring to make cold water to enter in the water tank (5), then need use high-power Heat source device to realize, so, power consumption is big.

(2), because the efficiency of heating surface is not good, and mostly can't provide required hot water immediately in season in severe winter.

(3), because of using high-power Heat source device, so the volume of electric heater is big and Heavy Weight, use big electric current to improve relatively to use dangerous.

The purpose of this utility model provides the heater of the electric heater of a kind of efficiency of heating surface height and power saving.

For reaching above-mentioned purpose, the utility model by the following technical solutions:

The utility model mainly includes a high-efficiency thermal source capsule, an one spiral heating conduit and an insulation cover, the spiral heating sheathed catheter is located at high-efficiency thermal source capsule body, significantly increased the heating surface (area) (HS of high-efficiency thermal source capsule to heating duct, and prolonged heat time heating time of the cold water in the heating duct of flowing through relatively, and being entered by the water inlet of heating duct, cold water had suitable temperature when flowing out by delivery port more, and can effectively improve the temperature of water at short notice, in addition, outside high-efficiency thermal source capsule and heating duct, be provided with the good insulation cover of an insulating properties, concentrated so that heat energy is coated effectively, to improve the thermal efficiency.

The utility model will be further described below in conjunction with the embodiment accompanying drawing:

Fig. 1 is the utility model perspective exploded view.

Fig. 2 is the utility model combination cross-sectional schematic.

Fig. 3 is a use illustration intention of the present utility model.

Fig. 4 is the perspective exploded view of common heater.

Fig. 5 is the combination cross-sectional schematic of common heater.

(1) be that electric heater, (2) are that insulation cover, (5) for water tank, (53) for opening, (6) be traditional type Heat source device for water inlet, (32), (52) for delivery port, (4) for heating duct, (31), (51) for high-efficiency thermal source capsule, (3).

As Fig. 1, Fig. 2, shown in Figure 3, the utility model is located in the electric heater (1) and is used, the utility model includes a high-efficiency thermal source capsule (2), one heating duct (3) and an insulation cover (4), wherein, heating duct (3) spiral unrolls, and a few are located at outside the high-efficiency thermal source capsule (2), one end of heating duct (3) is water inlet (31), the other end is delivery port (32), cold water enters heating duct (3) by water inlet (31), because heating duct (3) unrolls outside high-efficiency thermal source capsule (2) with spiral, increased contact area, prolonged the heat time heating time of cold water relatively, when water is flowed out by delivery port (32), had suitable temperature, thereby can effectively improve the temperature of water at short notice; In addition, outside the high-efficiency thermal source capsule (2) and heating duct (3) after combination, be arranged with the good insulation cover of insulating properties (4), concentrate,, thereby realize the high efficiency of heating surface and purpose of power saving with the raising efficiency of heating surface so that heat is effectively coated.

Claims

1, a kind of heater of electric heater, it is characterized in that: include a high-efficiency thermal source capsule (2), a heating duct (3) and an insulation cover (4), wherein, heating duct (3) spiral unrolls, and a few are located at outside the high-efficiency thermal source capsule (2), the one end is water inlet (31), and the other end is delivery port (32); Insulation cover (4) is coated on outside high efficiency thermal source device (2) and the heating duct (3).
