Description

Cross waterpipe type domestic electric heating water heater fast

The utility model relates to a kind of quick waterpipe type domestic electric heating water heater of crossing.

What the domestic electric heating water heater was general in existing technology is divided into two kinds: the instant water heater that a kind of PTC of being ceramic material is made, this water heater complex process, the cost height made from the PTC ceramics material.Must give heat during use just had hot water in 20 seconds, and returning to normal temperature by the high temperature that cuts off the power supply when this water heater is stopped using needed 3 minutes just can add cold water more later on.And owing to easily scale, this kind water heater hard water areas service life seldom; Another kind is an electric heating film water heater, and the shortcoming of this water heater is that the flow of water is little, volume is big, and flow is little can't to be used, and volume is big, is not easy to move.And the operating performance complexity, boiling water soruce is switched on then in advance when using.The Hou Guan water source will cut off the power supply earlier when inactive.Unique safety measure is an earth connection, but a lot of family does not have ground wire.The shortcoming of the maximum of this water heater is that hydraulic pressure hour can't be worked.

The purpose of this utility model is a kind of safe in utilization, easy to operate, quick waterpipe type domestic electric heating water heater of crossing of opening that valve is short to the time that goes out hot water, discharge can be controlled, hour also can working at hydraulic pressure of design.

Scheme of the present utility model is as follows: the centre of crossing water pipe 4 of circular pipe type penetrates electrothermal tube 3, and the two ends of electrothermal tube are that electric heating binding post 17,18 stretches out in the outside of crossing water pipe 4.Cross the helical form that is shaped as of water pipe 4, the shape of electrothermal tube 3 also is a helical form.An end and the water inlet 16 of crossing water pipe 4 communicate, and the other end and delivery port 2 communicate.Water inlet 16 and hydraulic pressure gauge tap 14 communicate.The structure of hydraulic pressure gauge tap is as follows, and the shell that polywater rifle 15 made of copper is positioned at the hydraulic pressure gauge tap is fixedlyed connected with shell 14.The top of polywater rifle 15 has a rectangular water jet 12, and circular copper pressure mandril 13 is enclosed within the top of polywater rifle 15, and the external diameter of the internal diameter of polywater rifle 15 and pressure mandril 13 is movable to be cooperated.Limit collar 20 is fixedlyed connected with pressure mandril 13, and is stuck in the termination of polywater rifle 15.One end of compression spring 11 is fixed on limit collar 20, and the other end is fixed on the magnet ring 10 that is positioned at pressure mandril 13 tops.One control nut 9 is arranged at the top of magnet ring 10, and control nut 9 and magnet ring have the distance about an about 3mm, and control nut 9 is connected with the shell of hydraulic pressure gauge tap 14 by being threaded.The center fixation of control nut 9 has tongue tube stationary pipes 8, and the center fixation of tongue tube stationary pipes 8 has tongue tube 7.

The utility model novel structure, cost is low, the thermal efficiency is high.Have only 5 seconds kinds from the valve of fetching boiling water to the time that goes out hot water, the temperature of water can be adjustable in 35 ℃-85 ℃ the scope, and the flow of water is a per minute kind 1-4 liter, and no matter the flow size of water can be worked.As long as water is arranged, move on the pressure mandril, move on the magnet ring, the tongue tube attraction circuit is connected.Pressure mandril moves down rapidly when anhydrous, and magnet ring leaves reed switch circuit and disconnects.In control circuit, designed the electric leakage automatic protection circuit, will outage automatically in 0.1 second time when the leakage current less than 15mA exists.When surpassing water temperature, there is thermal protector to cut off circuit again and cuts off the power supply automatically.Reach the purpose of design that safe in utilization, easy to operate, hydraulic pressure hour also can be worked, discharge can be controlled fully.

Below in conjunction with drawings and Examples the utility model is illustrated:

Fig. 1-Fig. 3 is embodiment of the present utility model.

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is a circuit diagram of the present utility model.

As shown in Figure 1 and Figure 2, the centre of crossing water pipe 4 of circular pipe type penetrates electrothermal tube 3, crosses water pipe 4 usefulness red coppers and makes.The two ends of electrothermal tube are that electric heating binding post 17,18 stretches out in the outside of crossing water pipe 4.Cross the helical form that is shaped as of water pipe 4, the shape of electrothermal tube 3 also is a helical form.The length of electrothermal tube 3 is about about 1 meter.Cross the two ends soldering and sealing of water pipe 4, binding post 17,18 extends.An end and the water inlet 16 of crossing water pipe 4 communicate, and the other end and delivery port 2 communicate.Water inlet 16 and hydraulic pressure gauge tap 14 communicate.The structure of hydraulic pressure gauge tap is as follows, and the shell that purple polywater rifle 15 made of copper is positioned at the hydraulic pressure gauge tap is fixedlyed connected with shell 14.The purposes of polywater rifle 15 is in order to make water heater adapt to high water level and low water level, high water temperature and low water temperature.The top of polywater rifle 15 has a rectangular water jet 12, and circular red copper pressing pressure push rod 13 is enclosed within the top of polywater rifle 15, and the external diameter of the internal diameter of polywater rifle 15 and pressure mandril 13 is movable to be cooperated.Limit collar 20 is fixedlyed connected with pressure mandril 13, and is stuck in the termination of polywater rifle 15.One end of compression spring 11 is fixed on limit collar 20, and the other end is fixed on the magnet ring 10 that is positioned at pressure mandril 13 tops.One control nut 9 is arranged at the top of magnet ring 10, and control nut 9 and magnet ring have the distance about an about 3mm, and control nut 9 is connected with the shell of hydraulic pressure gauge tap 14 by being threaded.The center fixation of control nut 9 has tongue tube stationary pipes 8, and the center fixation of tongue tube stationary pipes 8 has tongue tube 7.When water process polywater rifle 15, the pressure of water backs down the pressure mandril 13 that is pressed in the water jet top, moves on the pressure mandril 13 to promote to move on the compression spring 11, drives to move on the magnet ring 10 to make tongue tube 7 adhesives, and control circuit is started working.Under anhydrous situation, pressure mandril moves down, and compression spring 11 moves down, and magnet ring leaves tongue tube, and circuit disconnects.With delivery port 2 water pipe connecting 1 with shower nozzle joins and polywater rifle 15 water pipe connecting 19 and running water pipe join.The outside of crossing water pipe 4 also is fixed with the temperature sensor 15 that joins with overheat protector WDJ.

The operation principle of control circuit is as shown in Figure 3: electric leakage Automatic Protection Switching DZ, when the leakage current less than 15mA existed, this holding circuit will outage automatically in 0.1 second time.R1, D1, indicator lamp LD form power indicating circuit, and R2, D3, HD form working indicating, an end of relay K J1 control full load, an end of relay K J2 control half load.The other end of electrothermal tube DR and relay K J3 serial connection control load.Overheat protector WDJ and tongue tube KS (7), power change switch K are connected in series, and are connected across the two ends of working power.
