[0014] 发热管2设在热水腔内下端的中部,出热水管13设在发热管附近,在发热管的中间设有一个由电机带动的搅拌叶片41,可以防止加热时发热管2的表面因为温度过高而产生水垢,加热过程中产生的空气由自动排气阀14自动排出,在发热管2外围可安装一个使加热均勻的导流筒,在搅拌叶片的驱动轴上端设有一个能限制定位筒下端位置的安全限位8。 [0014] The heat pipe 2 is provided in the central cavity of the lower end of the hot water, the hot water pipe 13 provided in the vicinity of the heat pipe, the heat pipe is provided in the middle of a stirring blade 41 driven by the motor, it is possible to prevent the heating tube 2 heating the surface temperature is too high because of scale formation, the heating process air generated automatically by the automatic exhaust discharge valve 14, the periphery of the heating tube 2 may be mounted a uniform heating of the draft tube, it is provided at the upper end of the drive shaft of the stirring blade a safe positioning cylinder can restrict the lower end position of the stop 8.

[0015] 在进水管上设有定位夹36,在储水桶上面的进水管上设有下限位32。 [0015] The retaining clip 36 is provided on the inlet pipe, the lower limit is provided in the outer tank 32 above the inlet pipe.

[0016] 定位筒上部的进水管处设有一个水量指示件9 ;水量指示件9由套在进水管段31 上的单向调节器91、外磁铁93和固定在定位筒上端部的定位内磁铁92组成,水量指示件9 能紧随定位筒6上下移动。 [0016] positioned at an upper water inlet pipe provided with a water indicator barrel 9; 9 indicated by a water jacket on the inlet pipe section 31 of the one-way actuator 91, the inner and outer magnets 93 fixed to the upper end portion of the positioning tubular positioning 92 magnet composition, the amount of water indicating member 9 immediately 6 can move up and down positioning cylinder.

[0017] 调节单向调节器91使水量指示件9只能够向下方向单向运动,在进水管3进水时,平衡孔M在平衡活门52的重力及进水压力的作用下处于关闭状态,隔热活塞5的中央孔51也被定位筒下端面62关闭,隔热活塞5在进水压力的作用下往下移动,定位筒6和水量指示件9同时向下方向移动一段距离后,即使停止进水,定位筒6不会上浮,实现隔热活塞5保位隔热作用。 [0017] The regulator actuator 91 so that the one-way water indicator 9 can be unidirectional downward motion, when the water inlet pipe 3, M equalizing hole is closed under the action of gravity and the water pressure balance valve 52 , insulative piston central aperture 515 is also positioned at the barrel end 62 is closed, the piston 5 moves downward under action of the water pressure, water and positioning cylinder 6 while indicating member 9 moves downward a distance insulation, even if the water is stopped, positioning cylinder 6 does not float, to achieve heat insulating effect of the piston 5 to secure his position. 当进水管3继续进水,热水腔11容积最小时,安全限位8顶住定位筒下端部62,使隔热活塞5与定位筒分离,冷水通过中央孔51流入出水管13。 When the water inlet pipe 3 continues, the volume of the hot water chamber 11 is minimum, safety stop 8 against the lower cylindrical portion 62 is positioned so that the piston 5 is separated from the heat positioning cylinder, cold water flows into the outlet pipe 51 through the central aperture 13. 当水量指示件9上的调节器91碰触下限位32后,改变为失去单向运动的功能,进水管3停止进水后,定位筒6向上浮起,中央孔51处于开启状态,使冷水腔12的水流入热水腔11,这样隔热活塞5 顺利上浮,实现自动回位的功能。 When the actuator 9 on the water indicating member 91 touches the lower limit 32, changes to the loss of function of unidirectional movement, after stopping the water inlet pipe 3, floats upward positioning cylinder 6, the central aperture 51 is turned on, cold water water chamber 12 flows into the hot water chamber 11, so that the smooth heat floating piston 5, the automatic return function. 当定位筒6和水量指示件9上浮到定位夹36位置时,由于隔热活塞5和定位筒6的浮力小于水量指示件9的吸合力,从而使定位筒6的上端停留在定位夹36处,中央孔51随后被关闭。 When the clip 36 is positioned at the positioning cylinder member 6 and 9 indicate the amount of water to the float position of the positioning clamp 36, since the heat of the piston 5 and the buoyancy positioning cylinder 6 is less than the water suction force indicating member 9, so that the upper end of the positioning cylinder 6 visit the central aperture 51 is then closed. 当水量指示件9碰触定位夹36的同时,单向调节器91又改变到单向运动的控制位置,为下次运行做准备。 While the indicator 9 when water touches the retaining clip 36, and the one-way actuator 91 is changed to control the position of the one-way movement, in preparation for the next run.

[0018] 通过手动改变定位夹36在进水管段31上的位置,从而可以改变隔热活塞5的位置,实现热水器的变容功能,节约能源。 [0018] 36 positions on the inlet pipe section 31 by manually changing the retaining clip, so that heat can be changed position of the piston 5, the water heater to achieve the varactor function, energy saving.

[0019] 本发明在安装好未使用之前,先使定位夹36远离下限位32,而水量指示件9靠近下限位32,使定位筒6伸入冷水腔12内的部分最多。 [0019] Before the present invention is installed is not used, the positioning clamp 36 away from the first limit position 32, indicating the amount of water close to the lower limit 32 member 9, the positioning cylindrical portion 6 extends into a cavity within a maximum of 12 cold. 在第一次储水时,无需打开出水管,隔热活塞5位于储水桶1的最低部,定位筒6压在安全限位8上,冷水通过中央孔51流入储水桶1,储水桶中的空气通过自动排气阀33排出。 In the first reservoir, without opening the outlet pipe, heat storage tank 1 is located in the lowest portion of the piston 5, 6 pressed against the positioning cylinder safety limit 8, flows into a storage tank, the cold water storage tank 51 through the central bore air 33 is discharged through the automatic vent valve. 当水注满后,定位筒6和隔热活塞5先后上浮,直至水量指示件9与定位夹36接触。 When full water column, positioning cylinder 6 and the piston 5 has insulation float until the water indicating member 9 in contact with the retaining clip 36.

[0020] 当需减少加热水量时,只需往下边同时移动水量指示件9与定位夹36,此时中央孔51被关闭,由于热水腔11的压力大于冷水腔12,平衡活门52克服自身重力开启,热水腔11的水通过平衡孔M流入冷水腔12,从而实现热水腔11容量减小的目的。 [0020] When it is desired to reduce the heating water, water simply moves down side while indicating member 9 and the retaining clip 36, the central bore 51 is closed at this time, since the pressure chamber 11 is greater than the cold water chamber 12, the shutter 52 to overcome its own balance open gravity, hot water chamber 11 through the balance hole 12 M flows into the cold chamber, hot chamber 11 in order to achieve the purpose of reduced capacity.

[0021 ] 本发明的电热水器在环境温度较高或对热水温度要求不高的情况下,可以使用即热式。 [0021] The electric water heater of the present invention under ambient or high temperature hot water in less demanding situations, may be used tankless. 使定位夹36和水量指示件9靠近下限位32,此时定位筒下部62与安全限位8刚好接触。 Clip 36 and the positioning member 9 indicating the amount of water close to the lower limit 32, a lower case 62 and the positioning cylinder just touches the stopper 8. 启动电热水器后,进水压力能在很短的时间内把中央孔51开启,冷水流经发热管2 被快速加热后,由发热管2附近的出水管13流出。 After starting the water heater, the water pressure in the central hole 51 can be opened in a very short period of time, the cold water flowing through the heating pipe 2 is rapidly heated, flowing out from the heating tube 2 near the outlet pipe 13. [0022] 实施例2 : [0022] Example 2:

本实施例只需将实施例1旋转180°安装,进水管位于贮水桶的下方,隔热活塞将储水桶内腔分隔成下面为冷水腔,上面为热水腔;定位筒和隔热活塞的综合比重大于水,平衡活门的综合比重小于水,同时自动排气阀可省去不用。 Example 1 of the present embodiment is mounted rotated by 180 ° Just embodiment, the reservoir is located below the inlet pipe of the water tub, heat piston cavity into storage bins following a cold water chamber, to above the water chamber; positioning cylinder piston and insulation comprehensive specific gravity than water, the comprehensive balance of the shutter is less than the specific gravity of water, while the automatic vent valve can be omitted without.
