Description
Technical field
The present invention relates to the electric heater of the quick-heating type aluminium bag electrothermal tube heating that water flow switch controls.
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 invention 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.
Summary of the invention
The electric heater of the quick-heating type aluminium bag electrothermal tube heating that water flow switch of the present invention controls, is made up of water flow switch 20, water tank 12, electric heating element 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 electric heating element 13 has heating wire in metal tube, with magnesia powder, heating wire and metal pipe-wall are kept apart, magnesia powder is formed as insulating barrier, and with aluminium alloy by metal electric heat pipe 13 and metal water circulation road, is integrated by the technique of welding or casting.
Described instantaneous water heater refers to that water tank capacity is very little, and water flows through namely by the electric heater heated, and many electrothermal tubes 13 is housed in water tank and controls electrothermal tube circuit conducting or closedown by water flow switch 20, determines different electrothermal tube work or do not work by driving switch 21; 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.
Beneficial effect of the present invention 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.
Accompanying drawing explanation
Fig. 1 Fig. 2 is the Water flow switch structure figure of water jet propulsion formula by microswitch break-make, and Fig. 1 is closed condition, and Fig. 2 makes microswitch on-state for there being water flow;
Fig. 3 is microswitch structure schematic diagram
Fig. 4 Fig. 5 is the structural representation that water flow switch directly promotes contact
Fig. 6 Fig. 7 Fig. 8 is the electric heater structural representation of the quick-heating type aluminium bag electrothermal tube heating that water flow switch controls
Detailed description of the invention
In accompanying drawing, the main body 1 of water flow switch, cover plate 2, seal 3, impeller 4, spring or spring leaf 5, install cover plate 6, microswitch 7, stationary contact 8, movable contact 9, terminal 10, the pushing pin 11 of microswitch, water tank 12, electric heating element 13, water inlet pipe 14, outlet pipe 15, shell 17, water flow switch 20, driving switch 21, the out-of-date i.e. heating water of current stay vertical utensil 22.
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. 6 Fig. 7 Fig. 8 is the electric heater structural representation of the quick-heating type aluminium bag electrothermal tube heating that water flow switch controls, 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 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.
The water stream channel that electric heating element 13 described in Fig. 6 Fig. 7 Fig. 8 is made by 13-1 heating wire, 13-2 magnesia powder, 13-3 metal tube, 13-4 aluminium alloy, 13-5 metal material, 13-7 binding post, 13-8 Inlet and outlet water interface are formed; And be formed as the out-of-date i.e. heating water of current stay vertical utensil 22; Described being integrated is integrated with the Combination of Methods of aluminum alloy by metal electric heat pipe and water stream channel welding or casting.
Product in accompanying drawing, water temperature display can adopt digital-scroll technique or fuzzy display, and in figure, arrow is water (flow) direction.
