Description
Technical field
The present invention relates to a kind of electric heater, specifically a kind of open type electric water heater.
Background technology
The electric heater that existing family or hotel guest-room are used mainly is a closed electrical water heater, closed electrical water heater mainly by inner bag, temperature control element, relief valve, stretch into the heating in the inner bag, the water inlet pipe that communicates with inner bag and outlet pipe, inner bag is an obturator that only communicates with inlet tube and outlet tube, water inlet pipe communicates for a long time with running water pipe, the hot water inlet port of outlet pipe and mixed water valve joins, and the cold water inlet port and the running water pipe that wherein mix water valve join.Open mixed water valve during use, in the inner bag under the hydraulic pressure effect of hot water in running water pipe the mixed water valve through correspondence discharge.When not using, because the mixed water valve of its configuration is the unidirectional delivery port of cutting out, and makes it be in closed state, so its inner bag is under the closed state of HTHP for a long time, so just brought great shortcoming to closed electrical water heater: there is great hidden danger in short, poor stability of life-span; Because inner bag is under the closed state of HTHP for a long time, metal inner tube and heating under the HTHP effect very easily by corrosion, thereby shortened its life-span, in case and pressure-reducing valve is malfunctioning will blast, cause danger.So people's panesthesia is dangerous to electric heater, hope can solve the problem that existing product exists.And owing to want pressure-bearing, so inner bag all must be columned spherical structure, the profile of product is also single.
Summary of the invention

The specific embodiment
Below in conjunction with accompanying drawing open type electric water heater of the present invention is described in further detail.
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, open type electric water heater of the present invention mainly mixes water valve 7 by water tank 1, electric heating tube 2, delivery port pipe 3, water inlet pipe 4, water dropping openings pipe 5, gondola water faucet 6 with ganged switch and forms.Electric heating tube and delivery port pipe are positioned at water tank, delivery port pipe, water inlet pipe, gondola water faucet mix water valve with ganged switch and are connected, the water dropping openings pipe top mouth of pipe is positioned at the top of the high liquid level (HLL) of water tank, and delivery port pipe height is lower than the height of water dropping openings pipe, is higher than the height of electric heating tube.The water dropping openings of water dropping openings pipe connects a mozzle 8.Ganged switch mixes water valve and comprises fixed valve plate 9 and moving valve plate 10, moving valve plate can move up and down along the surface of fixed valve plate, moving valve plate is provided with cold water transition region 101 and hot and cold water mixed transition district 102, and fixed valve plate is provided with hot and cold water and blends oral region 91, hydrothermal area 92, running water time zone 93 and cold water area 94.Cold water area and hydrothermal area, running water time zone are adjacent, and are positioned at the below of hydrothermal area and running water time zone.
First kind of embodiment of open type electric water heater of the present invention as shown in Figure 1, water tank is installed a water intaking valve 11 first, water intaking valve links to each other with running water pipe 12 first.Water intaking valve and ganged switch mix the use of water valve divided function first, and water intaking valve is just just opened when feed-tank is intake in the first time first, and when normally using afterwards, it all is in closed condition always.When first time water filling, open water intaking valve first, close ganged switch and mix water valve, begin water inlet this moment in the water tank, when the water outlet of water dropping openings place, proves that this water tank filled with water, close water intaking valve first this moment, in the future when normal the use, this first water intaking valve all must be in closed condition always.When electric heating tube begins to heat, have water droplet and flow out from water dropping openings, until being heated to design temperature, the external mozzle in water dropping openings place can drain in the drainage pipeline dripping, but must keep unimpeded with atmosphere always.When water, to open ganged switch and mix water valve, the entery and delivery port of the mixed water valve of ganged switch this moment all is in open mode.After using up water, close ganged switch and mix water valve, the entery and delivery port of the mixed water valve of ganged switch this moment all is in closed condition.At this moment, can be the same by the enclosed type electric heater, by the pressure water supply of running water.Fig. 2 is second kind of embodiment of open type electric water heater of the present invention, and this embodiment adopts mechanical integral type valve body structure.When first time water filling, open ganged switch and mix water valve, this valve is in water inlet and opens and the delivery port closing state, begin water filling in the water tank this moment, when the water outlet of water dropping openings place, prove that this water tank filled with water, close ganged switch and mix water valve this moment, and this is closed entery and delivery port that ganged switch mixes water valve and all is in closed condition.In the operation principle of water tank heating and use as first kind of embodiment.Fig. 3 is the third embodiment of open type electric water heater of the present invention, this embodiment adopts electromagnetic type valve body computer control structure, form the ganged switch magnetic valve of synchro switch by water inlet magnetic valve 13 and delivery port magnetic valve 14, control its switch by the computer plate again.During user's water filling for the first time, select " state of water filling for the first time ", this moment, the water inlet magnetic valve of ganged switch magnetic valve was opened and the delivery port closed electromagnetic valve, begin water filling in the water tank this moment, when the water outlet of water dropping openings place, prove that this water tank filled with water, this moment, the user closed " state of water filling for the first time ", when normal the use, all can not use " state of water filling for the first time " function in the future.When electric heating tube begins to heat, have water droplet and flow out from water dropping openings, until being heated to design temperature, the external mozzle in water dropping openings place can drain in the drainage pipeline dripping, but must keep unimpeded with atmosphere always.When water, the user selects " user mode ", promptly opens the ganged switch magnetic valve, and the magnetic valve of the entery and delivery port of ganged switch magnetic valve all is in open mode at this moment.When water not, the user selects " closed condition ", promptly closes the ganged switch magnetic valve, and this moment, the magnetic valve of entery and delivery port of ganged switch magnetic valve all was in closed condition.When user mode, the user can regulate " water temperature adjusting " knob, and the mixed proportion by hot and cold water is adjusted to suitable user mode with water temperature.So, the user selects different functions and user mode, can be the same by the enclosed type electric heater, and by the pressure water supply of running water.
Because electric heater of the present invention is a unenclosed construction, water tank does not bear pressure, so its structure is not subjected to the traditional spheroidal structural limitations yet, can make polymorphic structures such as various ellipses, and its shape and material also can be more extensive.
