Description

The electric heater of the quick electrothermal-film heating of vertical type water flow on-off control

Technical field

The present invention relates to the electric heater of the quick electrothermal-film heating of vertical type water flow on-off control.

Background technology

At present the control method of countries in the world electric heater has two kinds, a kind of be use type liquid expansion temperature controller to the temperature setting in water tank, after energising, electrothermal tube starts to warm up, and stops heating after reaching temperature, when the temperature in water tank declines, heat again, constantly repeat, when exceeding design temperature, cut off the electricity supply, it is referred to as mechanical type control method, liquid expansion type controls, and energising continuously in 24 hours, wastes the energy；When temperature control inefficacy meeting laser heating, water heater is made to explode；Another kind is to use microcomputer chip and relay and other electron component, hydrous water flow sensor, when measuring water flowing, then starting electrothermal tube by relay to work, this electronic controller has tens of electrons element, hundreds of contacts, easily producing fault, cost is the highest；The present invention provides a kind of by water flow switch, the direct control method driving electrothermal tube to be turned on or off and corresponding water heater structure.

Summary of the invention

The electric heater of the quick electrothermal-film heating of vertical type water flow on-off control of the present invention, is made up of water flow switch 20, water tank 12, electrothermal tube 13, water inlet pipe 14, outlet pipe 15, shell 17 etc.；Described water flow switch 20 is made up of main body 1, cover plate 2, simultaneously promotion sealing member 3 and impeller 4, spring or spring leaf 5, installation cover plate 6, microswitch 7, stationary contact 8, movable contact 9, terminal 10, the pushing pin 11 of microswitch, in main body 1, the passage of water inlet and water outlet is not directly to communicate, but separated by cover plate 2, when there being water to flow, water can promote cover plate 2, simultaneously promotion sealing member 3 and impeller 4 and make movable contact 9 contact with stationary contact 8, circuit turn-on；Current are closed, and circuit disconnects；Owing to electrothermal tube has more than one, different temperature need one or a few electrothermal tube to work, driving switch 21 determine.

Described electrothermal tube 13 is to have Electric radiant Heating Film outside nonmetal quartz ampoule, plates the outer water flowing of electric heating membrane pipe in pipe in water flowing or pipe；Two ends seal, connect into the path of current, be configured to one energising after water flow through i.e. add hot water in vertical utensil 22, in this outer water tank 12 also have metal electric heating pipe.

The water tank 12 of described quick-heating type electric water heater, is to use nonmetallic materials injection or blow molding process manufacture, or uses metal material manufacture, current are out-of-date i.e. add hot water in vertical utensil 22, be placed in outside water tank 12；Water tank 12 has metal electric heating pipe；Controlled electrothermal tube circuit on and off by water flow switch 20, driving switch 21 determine different electrothermal tube work or do not work；The water inlet of water flow switch 20 and the passage of water outlet are not directly to communicate, but are separated by cover plate 2, and when there being water to flow, water can promote cover plate 2, simultaneously promotion sealing member 3 and impeller 4, and makes movable contact 9 contact with stationary contact 8, circuit turn-on；Current are closed, and circuit disconnects.

Described tank pressure controlling organization 23, is made up of main body 23-1, the valve 23-2 being contained in main body, and sealing member 23-3 and spring 23-4, is contained in inlet channel or water flow switch；During water inlet, spring is opened by pipe-line system pressure, water inlet, and when outlet misloading or dead by resistance, in water tank 12, pressure is within progressively increasing to 0.2mpa, and water inlet can be automatically switched off under valve 23-2 effect, it is ensured that safety.

Beneficial effect of the present invention and novelty are directly to control being turned on or off of electrothermal tube with current, and when having water to flow, electrothermal tube is connected, and water disconnects when closing automatically.

Detailed description of the invention

In accompanying drawing, water flow switch main body 1, cover plate 2, sealing member 3, impeller 4, spring or spring leaf 5, cover plate 6 is installed, microswitch 7, stationary contact 8, movable contact 9, terminal 10, the pushing pin 11 of microswitch, water tank 12, electrothermal tube 13, water inlet pipe 14, outlet pipe 15, shell 17, water nozzle 18, preheating switch 19, water flow switch 20, driving switch 21 water flow through i.e. add hot water control parts 23, mechanical water resistance 24 in vertical utensil 22, tank pressure.

Fig. 1 to Fig. 5 is water flow switch 20, it is made up of main body 1, cover plate 2, sealing member 3, impeller 4, spring or spring leaf 5, installation cover plate 6, microswitch 7, stationary contact 8, movable contact 9, terminal 10, Fig. 1 Fig. 2 uses microswitch 7, Fig. 4 Fig. 5 is directly to make contact and terminal installing on cover plate 6, the two function is identical with use, Fig. 1 Fig. 4 Fig. 5 is water route closed mode, and circuit disconnects；Fig. 2 is that water forces cover plate 2 to move in flow regime, the strength by water, moves sealing member 3 and impeller 4 the most simultaneously, promotes the pushing pin 11 in microswitch, makes movable contact and stationary contact combine, circuit turn-on；If closedown water route, then circuit disconnects；The shape of Fig. 4 cover plate 2 is different, and cover plate 2 has multiple hole, when discharging water, promotes and moves on cover plate 2, and water flows from hole；On the body 1, inlet channel and water outlet water channel are not straight-through, it is necessary to making cover plate 2 move water could circulate mutually；When closing due to water channel, the feed water inlet of main body 1 is closed by cover plate 2 automatically, and stationary contact and movable contact in Fig. 4 Fig. 5 only illustrate one group in figure, actual product can make many groups.

Fig. 8 is the electric heater structural representation of the quick electrothermal-film heating of vertical type water flow on-off control, and in figure, water flow switch 20, driving switch 21, electrothermal tube 13 cooperating, driving switch 21, have rotary and button type structure；The function of the two is identical；In figure, water flow switch 20 uses microswitch 7, makes, according to Fig. 4 Fig. 5, the structure that movable contact is combined with stationary contact, and function is identical；Equipped with electrothermal tube 13 in water tank 12, have outside water tank current out-of-date i.e. add hot water in vertical utensil 22；When discharging water, water flow switch 20 makes microswitch pushing pin 11, promotes movable contact 9 to contact with stationary contact 8, now, and the electrothermal tube work the most different by driving switch 21；Guan Shui, circuit disconnects automatically.

Described water tank 12 is molded by metal or nonmetallic materials or blowing makes, and water inlet pipe 14 and outlet pipe 15, by length > non-metallic pipe of 200mm makes, and for mechanical water resistance 24, after life-time service, even if electrothermal tube punctures, make that water is charged to be also ensured that, go out water security.

Product in accompanying drawing, water temperature shows can use digital-scroll technique or fuzzy display, and in figure, arrow is water (flow) direction.
