Abstract

The utility model relates to an electric heating device, which comprises a water tube, a bottom joint, a top joint, a water sealing cap and an upper terminal box, wherein, the bottom joint, the water tube, the top joint and the water sealing cap are orderly connected to form a heating chamber in which a heating tube is arranged, and the heating tube is fixed to the water sealing cap box. The utility model has the advantages of safety, easy installation, easy use, easy regulation of water temperature, low cost and easy maintenance without occupation area or water pressure requirement, and the utility model can be used so long as water flows and is hard to be damaged.

Description

Tubular type instant heating adjustable electric shower

Commercially available shower can be divided into two big classes now: gas heater and electric heater, the latter can be divided into storage-type and Instant heating type two groups again.They mainly contain following some shortcomings part:

1, feels unwell entirely.Gas heater unavoidably can produce toxic gases such as CO when using, although taked many measures in design and installation, it is reported, the whole nation is annual deadly still hundreds of because of using the gas heater shower to poison.

2, volume is big, installs inconvenient.Storage-type electric water heater weight is big, and volume is also big, and is fixing quite difficult on the wall.Gas water heater except that must be fixing on the wall, also many places perforating on the wall is with by hot and cold water and liquefied gas pipeline; What have also must adorn smoke discharging pipe.In addition, the fixing not only side of occupation of land but also not attractive in appearance on the wall.

3, the now auto-controls that adopt of the firepower of gas heater, discharge, water temperature, the many meticulous parts in the inside in case be out of order, overhaul very difficult more.

4, require certain hydraulic pressure.Present commercially available gas heater and instant electric water heater all require hydraulic pressure at 0.2kg/cm ²More than could start use.

5, instant electric water heater's power only 2,4,6KW third gear altogether, under normal water consumption, every 2KW can improve 14.4 ℃ of water temperatures, such gear design obviously is extremely irrational, it also is extremely inconvenient using.The gear of 6KW in addition, electric current surpass 27 peaces, also are that the most of families of China ammeter can not bear at present.

6, price height.Existing commercially available all kinds of various water heaters, the most cheap every also reaches 700-800 unit, and storage-type electric water heater is also like this.Particularly Instant heating type electric heater, every of price the lowest is also above 1500 yuan.

The purpose of this utility model is to provide a kind of electric shower-bath simple in structure, easy for installation.

The purpose of this utility model is achieved in that it comprises water pipe, bottom fitting, top sub, water seal cap, last terminal box, bottom fitting wherein, water pipe, top sub, the water seal cap connects successively, constitutes heating chamber, is provided with heating tube in heating chamber, and heating tube is fixed on the water seal cap.

Above-mentioned heating tube is by copper pipe, resistance wire, and insulated porcelain sleeve is formed, and be contained in the copper pipe behind the insulated porcelain sleeve on the resistance wire string, and the two ends of resistance wire is all drawn from an end of copper pipe and entered terminal box.

The utility model has following advantage:

1, safety.It uses electric energy, does not produce so there is toxic gas.And adopted the totally enclosed insulation measures of part of to switch on.

2, easy for installation, the side of occupation of land not.Between present most of domestic hygiene the running water shower bath is arranged all, mostly be four distributive pipes that are about a meter; This product also is the water pipe that is about a meter, and the bottom can directly link to each other with four distributive pipes; Therefore, when this product is installed, only need former four distributive pipes are backed out, this product is screwed on, plug in again, can use.

3, be difficult to damage, very easily maintenance.This product does not have other moving component except the water power switch, so be difficult to be out of order in using, unique defect that may go out is that resistance wire blows; Because this product has been taked bigger safety coefficient when selecting resistance wire for use, and its condition of work is also better, does not contact water vapour and flow air, so extremely difficult oxidized corrosion and blowing; Even resistance wire has broken, also be very easy to find (every resistance wire all connects an indicator lamp) and replacing.And resistance wire has broken one or two, and is also little to normal use influence, because all the other resistance wires still can operate as normal.

4, other water heater all needs certain hydraulic pressure (0.2kg/cm ²) just can start to work, this product does not then require hydraulic pressure, can use as long as just there are flowing out.

5, easy to use, water temperature is regulated easily.

6, price is low.

Below in conjunction with accompanying drawing structure of the present utility model is done detailed explanation

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the utility model section structure schematic diagram

Fig. 3 is the utility model heating tube 7 structural representations

The utility model comprises water pipe 1, bottom fitting 2, top sub 3, water seal cap 4, last terminal box 5, wherein bottom fitting 2, water pipe 1, top sub 3, water seal cap 4 connects successively, constitutes heating chamber 6, is provided with heating tube 7 in heating chamber 6, and heating tube 7 is fixed on the water seal cap 5.

Heating tube 7 is by copper pipe 8, resistance wire 8, and insulated porcelain sleeve 10 and 11 is formed, and be contained in the copper pipe 8 after resistance wire 9 strings are gone up insulated porcelain sleeve 10 and 11, and the two ends of resistance wire 9 is all drawn from an end of copper pipe and entered terminal box 5.
