Abstract
The utility model relates to a technology of an electric water heater. The utility model has a structure that a plug with a leakage protector is connected with a hydrodynamic pressure switch which is connected with a heating electrode through an electrode rod. A water pipe is connected with the hydrodynamic pressure switch and the heating electrode. When the utility model is used, a heating power supply is opened and closed by the hydrodynamic pressure switch. The utility model with convenient operation and high safety is a water heater suitable for places, such as households, hotels, offices, etc.
Description
The utility model relates to the electric heater technology.
In recent years, various water heaters flood the market, and enter huge numbers of families, though some small water heaters are wherein also arranged, mostly have following shortcoming:
1. not automatically control: when the user uses, the tap of fetching boiling water earlier, after press the switch that connects power supply, after finishing using, close electricity earlier, close water again, if the order of switch has been made a mistake the easy burn-out water heater when user uses.
2. there is not the earth leakage circuit-breaker device: when leakage current surpasses certain value, electric shock accidents takes place easily.In a word, existing small water heater is not automatic control, and dangerous.
The purpose of this utility model is, provide a kind of have earth leakage protective, safe and practical, microminiature water heater automatically.
The purpose of this utility model is achieved in that one is connected with the hydrodynamic pressure switch with the plug of the band earth leakage protective device of electric power connecting only, and the hydrodynamic pressure switch is connected with heating electrode through electrode stem; Water pipe water receiving dynamic pressure switch and heating electrode.During work, rely on the hydrodynamic pressure switch to open and turn-off heating power supply, water flowing is then switched on, the then outage of cutting off the water supply.And, therefore use safe and reliable because earth leakage protective is arranged.
Below in conjunction with accompanying drawing, the utility model is stated it in detail.
Accompanying drawing 1 is a structure chart of the present utility model;
Among the figure: 1. power supply; 2. switch; 3. fusible link; 4. plug; 5. indicator lamp; 6. button; 7. SR; 8. rubber tube; 9. top cover labyrinth; 10. upper reed plate; 11. following reed; 12. screw; 13. hydrodynamic pressure switch; 14 push rods; 15. pressure sensing diaphragm; 17,18. electrode stems; 19. heating electrode; 20. heating electrode; 21. garden dish type ground line electrode; 22. main support; 23. shell; 24. shower nozzle; 25. tube connector 26. tapses; 27. water inlet pipe; 28. water storage cavity; 29. water storage cavity.
Structure of the present utility model is as shown in Figure 1: the opening part in outer cover of water heater 23 sides is connected to tube connector 25, is water inlet pipe 27 in the middle of it, and water inlet pipe 27 joins with main support 22; Opening part at the top seal of shell 23 lid 9 is equipped with electro-insulating rubber pipe 8, on the top of water inlet pipe 27 are sensor water storage cavities 28, be hydrodynamic pressure switch 13 above it, below water storage cavity 28, be connected with firewire electrode water storage cavity 29, it below water storage cavity 29 live wire heating electrode 19, center line heating electrode 20 live wire heating electrodes 19 receiving electrode bars 16, electrode stem 16 is connected with reed 11 under the switch live wire; Center line heating electrode 20 is connected with center line electrode stem 17 and ground wire electrode stem 18, and taps into respectively in the plug 4 of band earth leakage protective device; Switch live wire upper reed plate 10 on hydrodynamic pressure switch 13 is connected with band earth leakage protective device plug 4; The plug 4 of band earth leakage protective device connects fusible link 3 and connects switch 2 again; Below shell 23, dish type ground, the garden line electrode 21 of band mesh is housed, shower nozzle 24 is equipped with in its below.
The structure of hydrodynamic pressure switch 13 of the present utility model is: in hollow becomes the hydrodynamic pressure switch 13 of shape, shape pressure mandril 14 is housed, pressure sensing diaphragm 15 thereunder is housed; Top left side at hydrodynamic pressure switch 13 is equipped with reed 11 down, and upper reed plate 10 is housed on its right side; Upper and lower reed 10,11 is fastening by screw 12.
On the plug 4 of band earth leakage protective device of the present utility model indicator lamp 5 is housed, button 6, SR 7.
During use; water heater tube connector 25 of the present utility model is connect running water pipe through running water switch 6; to connect with the mains 1 with the plug 4 of earth leakage protective device again; open water tap; water enters sensor water storage cavity 28 through water inlet pipe 27; water pressure pushing pressure sensing diaphragm 15; pressure sensing diaphragm 15 promotes push rod 14; push rod 14 will descend reed 11 upwards extremely to contact with upper reed plate 10 on the top; then circuit is connected, and heating electrode 19,20 is after flowing to the water heating of water storage cavity 29; through dish type ground, the garden of band mesh line electrode 21, at last from shower nozzle 24 ejections.
The utility model volume is little, and low cost of manufacture is easy to use, and safety is regulated water temperature and only need be regulated water tap.Can be widely used in places such as family, hotel, office, wide application prospect is arranged.
