Description

The heat pipe-type quick electric water heater

The utility model belongs to water heater, is specifically related to a kind of electric heater that adopts the electrothermal tube heating.

Electric heater is a kind of low-pressure electronic equipment product that converts electrical energy into heat energy.The electric heater of Xiao Shouing is of a great variety in the market, and comparatively simple and inexpensive electric heater generally adopts the battery lead plate heating, and the life-span is short, and it is convenient inadequately to install, and needs special earth connection, even so still electric shock accidents can take place because of ground connection is unreliable.In addition, the electric heater that also has utilizes all-metal to be the main body natural grounding, can avoid electric shock accidents to take place, but owing to metal can get rusty in oxidation, will cause the ostium excurrens obstruction and electric heater is scrapped.

The purpose of this utility model is to provide a kind of employing electrothermal tube heating, natural grounding and electric heater safe and reliable, that the life-span is long.

Heat pipe-type quick electric water heater of the present utility model, comprise a water heater main body with inside and outside shell, inner chamber in main body is installed electrothermal tube, inserts joint that is connected with tap and the water inlet band pipe that is connected with the inserts joint are installed on the main body, have one to be connected lead with band between the pipe at electrothermal tube, the main body inner chamber is sealed by bottom end cover, between shell and the inner casing for walking the hydrospace, fountain head is installed in its lower end, and there is apopore the upper end of inner chamber.

Electric heater volume of the present utility model is little, easy for installation.When electrothermal tube when fatigue limit is used, or when meeting special circumstances fusing, electric current will be along the connection lead between electrothermal tube and the band pipe by water pipe and the earth connection, moment is with the tubular type fuse melting and cut off the electricity supply.Therefore, use is as safe as a house reliable.Main body of the present utility model adopts engineering plastics to make, and is difficult for getting rusty, and be 5-6 times of metal master water heater service life.

The utility model is described in further detail below by accompanying drawing.

The heat pipe-type quick electric water heater structural representation that Fig. 1 the utility model proposes for basis.

Fig. 2 is Fig. 1 electric heater control chart.

1 is the water heater main body among the figure, the 2nd, and electrothermal tube, the 3rd, connect lead, the 4th, lead, the 5th, copper nut, the 6th, apopore, the 7th, loam cake, the 8th, " O " shape sealing ring, the 9th, band pipe, the 10th, bottom end cover, the 11st, fountain head, the 12nd, inserts joint, the 13rd, the pullswitch box, the 14th, fuse, the 15th, pullswitch, the 16th, indicator lamp.

As shown in the figure, this electric heater has a main body 1 with inside and outside shell, and electrothermal tube 2 is installed in the main body inner chamber, and there is apopore 6 its upper end, and the inserts joint 12 that is connected with tap is installed on the main body, and water inlet band pipe 9 is installed in the joint 12.Electrothermal tube 2 tightens together through pack into main body inner chamber and be connected with main body by two bolts at top of main body 1 end opening, and an end that connects lead 3 is welded on the appointment live wire pile crown of electrothermal tube 2, and the other end is welded on the internal head of band pipe 9.Be glued closed inner chamber bottom end cover 10, then " O " RunddichtringO packed into and tighten fountain head 11, the no plug wires end of switch enclosure 13 is fastened on the top external part of electrothermal tube 2 respectively with copper nut, note phase line simultaneously, loads onto and covers 7.Inserts joint 12 with water heater during use directly is connected on the water pipe, and presses wiring diagram and connect power supply, should be in the use by switching on after the first water flowing, and the order of afterwards cutting off the water of cutting off the power supply earlier when closing is carried out.During use, the tap of fetching boiling water, cold water will flow into the main body inner chamber along the band pipe 9 of joint 12, and the heating back goes out through the orifice flow of inside and outside cavity gap to fountain head 11 from top apopore 6, realizes the purpose of its fast electric heating water.Leaving water temperature can be regulated control by the water valve switch.In the use, in case meet the phenomenon of cutting off the water, cut off the electricity supply with pullswitch immediately, the water in the main body can guarantee that electrothermal tube is not burnt out.

The parts of the utility model electric heater all can be bought from the market or obtain through simple processing, and the Specifeca tion speeification of prepared electric heater is as follows:

A. power: 960～1500W

B. rated voltage: 210～250V

C. temperature: 38～45 ℃ (inflow temperature is measured in the time of 20 ℃)

D. heat time heating time:＜60S

E. flow: 35～58L/H
