Abstract
A water flow switch-controlled quick-heated PTC-heated electric water heater comprises a housing, a water tank, an electrothermal tube, an inlet pipe, an outlet pipe, a water flow switch, and a shift switch The water flow switch has a water-flow-pushed structure, and the water flow switch is composed of a main body, a cover plate, a seal member, a push member, a spring or spring leaf, a mounting cover plate, a microswitch, a fixed contact, a moving contact, a terminal, a push pin of the microswitch. A channel of the inlet pipe does not directly communicate with a channel of an outlet pipe, the channels are separated by the cover plate, a circuit can be switched on when the water flows, and the circuit is switched off when the water does not flow. The water flow switch cooperates with the shift switch.
Description
Technical field
The present invention relates to the electric heater of the quick-heating type PTC 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 that the quick-heating type PTC that water flow switch of the present invention controls heats, 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.
Positive temperature coefficient PTC thermo-sensitive material is made by described electrothermal tube 13, outside the metal tube that the both sides of ceramic heating assembly are attached to inner water flowing or inner chamber, after energising, tow sides can produce heat, pass through heat transfer, the water flow through in heating tube, what be configured to the out-of-date i.e. heating water of current stays vertical utensil (22).
Electrothermal tube 13 is housed in water tank, controls 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.
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.

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, installation cover plate 6, 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 flow switch 20, driving switch 21.
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 is the electric heater structural representation of the quick-heating type PTC 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; Many electrothermal tubes 13 are housed in water tank 12 discharge 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 electrothermal tube 13 is by positive temperature coefficient PTC thermo-sensitive material ceramic heating assembly, is attached to water stream channel side and forms, the water heating will flow through during energising.
Product in accompanying drawing, water temperature display can adopt digital-scroll technique or fuzzy display, and in figure, arrow is water (flow) direction.
