Description
The utility model relates to a kind of electric heating shower, particularly water-storage electric heater.
Existing water-storage electric heater structure includes water tank, electrothermal tube, automatically controlled part, water inlet portion and outlet part grades, and automatically controlled part is made up of attaching plug, temperature adjustment thermostat, water level demonstration electronic control circuit, indicator lamp etc.Water level shows that electronic control circuit controls indicator lamp by some water level informations that electrode transmitted of differing heights that are opposite in the water tank, to show the height of water level.Particularly place the pair of electrodes of about 1/3 height in water tank lower end, its information is controlled the break-make of electric current on the electrothermal tube to relay again through electronic control circuit, also promptly reached for 1/3 when height when water level, electrode touches the water conducting, makes the conducting of electronic control circuit master triode, relay changes state, its contact closure is connected electrothermal tube main circuit, makes electrothermal tube energising heating, and water level electrothermal tube no power during less than 1/3 height, purpose is to prevent dry combustion method, is unlikely the generation that makes electric heater damage and fire.In addition, temperature controller circuit idol when water temperature reaches institute's temperature adjustment and spends in the water tank, ends electronic control circuit master triode in electronic control circuit, and relay changes state, cuts off the electrothermal tube main circuit, in case overheated and dry combustion method.But, because electronic control circuit is at high tide wet for a long time and higher temperature work down, the electronic component performance instability, even occur damaging, make runaway electric circuit,, be in anhydrous dry-fire condition in case the control of electrothermal tube anti-dry is malfunctioning, the lighter's electrothermal tube blows, the water tank distortion, and weight person causes fire.
The purpose of this utility model provides a kind of water-storage electric heater that can effectively prevent dry combustion method.
The utility model structure includes water tank (1), electrothermal tube (5), automatically controlled part (2), water inlet portion (4) and water part (3), the thermoregulator electrical contact (K in the automatically controlled part (2)
2) and electrothermal tube (5) coupled in series, its key problem in technology is that automatically controlled part (2) includes ultralow pressure hydraulic pressure switch (23), its automatically controlled contact (K
1) and electrothermal tube (5) coupled in series, its hydraulic pressure controlling organization places water tank (1) inner underside.
For further strengthening anti-dry insurance degree, in automatically controlled part (2), set up temperature controller (24), its electrical contact (K
3) and electrothermal tube (5) coupled in series, its temperature-sensitive position adheres on the metal installing plate (51) of electrothermal tube (5).
The ultralow pressure hydraulic pressure switch of the utility model has only when water level to reach a certain height, and when the water tank inner underside had certain pressure intensity, the displacement that hydrostatic pressure promotes the hydraulic pressure controlling organization acquired a certain degree, and just makes automatically controlled contact closure.As because of improper use, just when not adding water, plug plug, and open thermoregulator, because the ultralow pressure hydraulic pressure switch is in opening, electrothermal tube does not have electricity, has prevented dry combustion method.Simultaneously, the temperature-sensitive position of temperature controller places on the metal installing plate of electrothermal tube, is in the electrothermal tube and the very fast intensification of installing plate of anhydrous heating, and the temperature controller action is cut off the electricity supply, and has increased the insurance degree of anti-dry.Go out in the use of hot water in the limit heating edge, water level progressively descends, and water temperature progressively rises so, and water temperature is raised to institute's temperature adjustment when spending, and the thermoregulator action is cut off the electricity supply; When water level was lower than certain altitude, the ultralow pressure hydraulic pressure switch was opened inadequately because of pressure, cuts off the electricity supply; If temperature continues to rise, the temperature controller action is also cut off the electricity supply.Can prevent the generation of dry combustion method so effectively.
