Technical field

The utility model relates to the electric heater of the quick electrothermal-film heating of vertical type water flow switch control rule.

Background technology

The control method of current countries in the world electric heater has two kinds, and a kind of is adopt type liquid expansion temperature controller to set the temperature in water tank, after energising, electrothermal tube starts to heat up, and stops heating after reaching temperature, when the temperature in water tank declines, heat again, continuous repetition, when exceeding design temperature, cuts off the electricity supply, be called mechanical type control method, liquid expansion type controls, and energising continuously in 24 hours, wastes energy; When temperature control inefficacy meeting laser heating, water heater is exploded; Another kind adopts microcomputer chip and relay and other electron component, and hydrous water flow sensor, when measuring water flow, then start electrothermal tube work by relay, this electronic controller has tens of electrons element, hundreds of contacts, easy generation fault, cost is also higher; The utility model provides a kind of by water flow switch, the control method that Direct driver electrothermal tube is turned on or off and corresponding water heater structure.

Utility model content

The electric heater of the quick electrothermal-film heating of vertical type water flow switch control rule described in the utility model, 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 by main body 1, cover plate 2, promote seal 3 and impeller 4, spring or spring leaf 5 simultaneously, cover plate 6 be installed, the pushing pin 11 of microswitch 7, stationary contact 8, movable contact 9, terminal 10, microswitch forms, in main body 1, the passage of water inlet and water outlet is not directly communicate, but separated by cover plate 2, when there being water flow, water can promote cover plate 2, promote seal 3 simultaneously makes movable contact 9 contact with stationary contact 8 with impeller 4, circuit turn-on; Current are closed, and circuit disconnects; Because electrothermal tube has more than one, different temperature needs one or a few electrothermal tube work, is determined by driving switch 21.

Described electrothermal tube 13 has 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, and connect into the path of current, and what after being configured to an energising, water flow through i.e. heating water stays vertical utensil 22, also has metal electric heat pipe in this outer water tank 12.

The water tank 12 of described quick-heating type electric water heater, is adopt nonmetallic materials injection moulding or blow molding process manufacture, or adopts metal material manufacture, the out-of-date i.e. heating water of current stay vertical utensil 22, be placed in outside water tank 12; Metal electric heat pipe is had in water tank 12; Control electrothermal tube circuit conducting or closedown by water flow switch 20, determine different electrothermal tube work by driving switch 21 or do not work; The water inlet of water flow switch 20 and the passage of water outlet are not directly communicate, but are separated by cover plate 2, and when there being water flow, water can promote cover plate 2, promote seal 3 and impeller 4 simultaneously, and movable contact 9 is contacted with stationary contact 8, circuit turn-on; Current are closed, and circuit disconnects.

Described tank pressure controlling organization 23, by main body 23-1, be contained in the valve 23-2 in main body, and seal 23-3 and spring 23-4 is formed, is contained in inlet channel or water flow switch; During water inlet, spring is subject to pipe-line system pressure, and water inlet is opened, and when delivery port misloading or dead by resistance, in water tank 12, pressure can be increased within 0.2mpa gradually, and water inlet can automatically be closed under valve 23-2 effect, guarantees safety.

The utility model beneficial effect and novelty directly control being turned on or off of electrothermal tube with current, and when having water flow, electrothermal tube is connected, and automatically disconnects when water is closed.

Detailed description of the invention

In accompanying drawing, water flow switch main body 1, cover plate 2, seal 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 chew 18, preheating switch 19, water flow switch 20, driving switch 21 water flow through i.e. heating water stays vertical utensil 22, tank pressure control assembly 23, mechanical water resistance 24.

Fig. 1 to Fig. 5 is water flow switch 20, be made up of main body 1, cover plate 2, seal 3, impeller 4, spring or spring leaf 5, installation cover plate 6, microswitch 7, stationary contact 8, movable contact 9, terminal 10, what Fig. 1 Fig. 2 adopted is microswitch 7, Fig. 4 Fig. 5 be by contact and terminal directly on installation cover plate 6, the two function is identical with use, Fig. 1 Fig. 4 Fig. 5 is water route closed condition, and circuit disconnects; Fig. 2 be water in flow regime, the strength by water forces cover plate 2 to move, also simultaneously hydrodynamic reciprocating sealing part 3 and impeller 4, the pushing pin 11 promoted on microswitch, movable contact and stationary contact is combined, 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, and when discharging water, promote cover plate 2 moves, water flows from hole; On the body 1, inlet channel and water outlet water channel are not straight-through, and cover plate 2 must be made to move water could circulate mutually; Due to water channel close time, the feed water inlet of main body 1 is automatically closed by cover plate 2, and stationary contact and movable contact in Fig. 4 Fig. 5, only illustrate one group in figure, and 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 switch control rule, water flow switch 20, driving switch 21, electrothermal tube 13 cooperating in figure, and driving switch 21, has rotary and button type structure; The function of the two is identical; In figure, water flow switch 20 adopts microswitch 7, and according to the structure that Fig. 4 Fig. 5 makes movable contact be combined with stationary contact, function is identical; Electrothermal tube 13 is housed in water tank 12, and what have the out-of-date i.e. heating water of current outside water tank stays vertical utensil 22; When discharging water, water flow switch 20 makes microswitch pushing pin 11, promotes movable contact 9 and contacts with stationary contact 8, now, and the electrothermal tube work really different by driving switch 21; Guan Shui, circuit disconnects automatically.

Described water tank 12 metal or nonmetallic materials injection moulding or blowing make, and water inlet pipe 14 and outlet pipe 15, make of the non-metallic pipe of length >200mm, for mechanical water resistance 24, after Long-Time Service, even if electrothermal tube punctures, water-band electricity also can be guaranteed, permeate safety.

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