Abstract
The utility model provides a heating body of an instantaneous water heater for heating water by adopting bare wire, comprising a cup body, an upper flange, a lower flange, a heating wire, a heat conducting block, a column guiding nut, a water inlet and a water outlet, wherein the upper flange and the lower flange are fixed on the upper surface and the lower surface of the cup body respectively; the heat conducting block is fixed on the upper flange; the column guiding nut is fixed on the lower flange by a washer; the water outlet is fixed on the lower flange; the water inlet is arranged on the side surface of the cup body; and the heating wire is encapsulated in the cup body and is directly contacted with the water. Compared with other heating technologies, the bare wire heating technology is adopted in the utility model, the more precise temperature control can be realized, and the water temperature can be precisely controlled to 0.5 DEG C. As the resistance wire is extremely fine, the contacting surface between the resisting wire and the water is small, the surface has low working temperature, the possibility that the incrustation is attached to the resistance wire is extremely low, and therefore, the heating body can be applied to the areas with hard water quality. The heating body has the advantages that the structure is simple, the heat exchange effect is good, the heating speed is quick, the heat efficiency is high, and almost no problems occur.
Description
Technical field: the utility model relates to a kind of calandria of immediately heating water heater, especially a kind of immediately heating water heater calandria that adopts naked silk heating.
Background technology: the common Electric radiant Heating Film heating technique of the general employing of the calandria of present immediately heating water heater, generally about 97%, firing rate is fast inadequately, and the thermal efficiency is lower for energy conversion efficiency.
Summary of the invention: at above-mentioned the deficiencies in the prior art, the utility model provides the immediately heating water heater calandria of the naked silk heating of employing that a kind of firing rate is fast, the thermal efficiency is high.
For achieving the above object, the technical solution adopted in the utility model is: adopt the immediately heating water heater calandria of naked silk heating, comprise a glass body, and upper flange, lower flange, heating wire, heat-conducting block draws the post nut, water inlet and delivery port.Upper flange and lower flange are separately fixed at the upper and lower surface of glass body.Heat-conducting block is fixed on the upper flange.Drawing the post nut is fixed on the lower flange by packing ring.Delivery port is fixed on the lower flange.The water inlet communicates with heating wire in the side of cup body.Heating wire is packaged in glass body, directly contacts with water.
The utility model adopts naked silk heating technique can realize more accurate temperature control with comparing than other heating techniques, and water temperature control can be as accurate as 0.5 ℃.Because of resistance wire is very thin, little with the contact area of water, surface Working Temperature is low, and incrustation scale is very low attached to the probability on the resistance wire, so the hard area of water quality also can be suitable for.This kind technical pattern is simple, and heat exchange effect is good, and firing rate is fast, and thermal efficiency height any problem can occur hardly.
Description of drawings:
Fig. 1 structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1: adopt the immediately heating water heater calandria of naked silk heating, comprise glass body 1, upper flange 2, lower flange 3, heating wire 4, heat-conducting block 5 draws post nut 7, water inlet 8 and delivery port 9.Upper flange 2 and lower flange 3 are separately fixed at the upper and lower surface of glass body 1.Heat-conducting block 5 is fixed on the upper flange 2.Drawing post nut 7 is fixed on the lower flange 3 by packing ring 6.Delivery port 9 is fixed on the lower flange 3.Water inlet 8 is in the side of glass body 8, communicates with heating wire 4.Heating wire 4 is packaged in glass body 1, directly contacts with water.
Operation principle: naked silk heating technique is to adopt the calandria of nichrome Cr20Ni80 resistance wire as immediately heating water heater, resistance wire is packaged in the heating cup, during water heater working, current enter heating cup from water inlet, flow through to be packaged in the resistance wire in the heating cup and to be heated.The design of the water route of product inside has a lot of bendings, and utilizing water itself is the characteristic of non-conductor, has increased by the design of rational water route that the resistance value of water makes the resistance decomposition voltage in the water pipe, reaches water outlet voltage and reaches safety standard, guarantees the security of using.
