Description
Technical field
The present invention relates to a kind of electric heater of the instant electric water heater's of having water-pressure starter, belong to the quick-heating type electric water heater technical field.
Background technology
The advantage of quick-heating type electric water heater is exactly water flowing energising, cut the supply of water and electricity, and what realize this function is exactly water-pressure starter.the water-pressure starter of existing most instant electric water heaters and electric hot water tap is just installed a hydraulic pressure switch, hydraulic pressure switch bears tap water pressure by single face and carrys out conducting, if hydraulic pressure switch is arranged on to water valve water inlet front, after water valve cuts out, hydraulic pressure switch still bears hydraulic pressure, and the pressure that bears is larger, can't realize the function of cutting the supply of water and electricity, therefore the heating part of existing most instant electric water heaters and electric hot water tap can only be arranged on water valve delivery port back, after water valve cuts out like this, not there are flowing out, hydraulic pressure switch does not just bear hydraulic pressure yet, automatic disconnection.
Also just because of this, for easy for installation, attractive in appearance and easy to use, existing instant electric tap is all that tap and electric heater are become one, and during installation, needs former mounted tap is removed, and causes unnecessary waste; And at cold district, when electric hot water tap does not use, because the remaining water in its water heating chamber and the water in tap water supply system cut off, the remaining easy freezing and expansion of water, cause the heating chamber deformed damaged, in serious situation, can explode, Product Safety and service life reduce greatly.
Existingly can be arranged on the water-pressure starter that the water valve water inlet uses previously and have following three kinds: pressure reduction disc type, gravity type and vane type also have the only a few quick-heating type electric water heater that these water-pressure starters are installed.
as shown in Figure 1 as Figure of description, existing pressure reduction disc type water-pressure starter is that water enters from the middle part of pressure differential disc high pressure chest, after water (flow) direction folding turnback, from upper hole, flow out, then flow to Venturi tube, on the aditus laryngis of Venturi tube, have a pressure port and communicate with the low-pressure cavity of pressure differential disc by pressure pipe, due to Venturi tube aditus laryngis place sectional area minimum, according to bernoulli principle, current accelerate herein, pressure drop, make the pressure of pressure differential disc right side high pressure chest apparently higher than the left side low-pressure cavity, so push rod drives microswitch work, when closing water valve, because water does not flow, the pressure of pressure differential disc both sides is identical, microswitch cuts out under the effect of the reset force of push rod.This apparatus structure is complicated, volume is large.
When the operation principle of existing gravity type water-pressure starter is anhydrous, magnetic patch falls down and drops on bottom surface under Action of Gravity Field, this moment, magnetic patch was away from sensor, the not conducting of magnetic switch sensor, in the situation that water flow is arranged, the current that up flow produce a climbing power to magnetic patch, when climbing power greater than magnetic patch weight magnetic patch be lifted, this moment, magnetic patch made sensor conducts near sensor.The gravity type water-pressure starter divides piston type and two kinds of structures of turnover plate type, and is as shown in Figure 2 as Figure of description.Piston type easily is subjected to the impact of impurity in water the stuck phenomenon that causes anhydrous dry combustion method to occur, and the deficiency of turnover plate type is that pendulum angle is too large.
The vane type water-pressure starter is that impeller, just by red switch, is equipped with little magnetic control on each blade when there being current out-of-date, Hall element conducting during the close Hall element of magnetic patch, and while leaving, Hall element disconnects.According to the umber of pulse that Hall element produces, can measure water velocity, according to water velocity, judge whether machine works and should export much power.This kind device also is divided into two kinds, and a kind of is axial type, and a kind of is tangential, as shown in Figure 3 as Figure of description.Axial type easily is detained impurity between support and impeller shaft, affect the rotation of impeller.
