Abstract

A quick-heating horizontal external luminous-energy-heated electric water heater controlled by a water switch comprises a shell, a water tank, electric heating tubes, a water inlet tube, a water outlet tube, the water switch, a gear switch, a button switch and the like. The water switch is of a water-pushed structure and comprises a main body, a cover plate, a sealing piece, a pushing piece, a spring or spring piece, a mounting cover plate, a microswitch, a stationary contact, a movable contact, a terminal and a push pin of the microswitch. Water inlet and outlet channels are not directly communicated but separated by the cover plate, a circuit is switched on when water flows, and the circuit is switched off when the water does not flow; the water switch cooperates with the gear switch, and a preheating switch is pressed down when water in the water tank needs to be preheated.

Description

The electric heater of the horizontal external luminous energy heating of the fast heat that water flow switch controls

Technical field

The present invention relates to the electric heater of the horizontal external luminous energy heating of fast heat 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 horizontal external luminous energy heating of the fast heat that water flow switch of the present invention controls, 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 is the carbon fiber pipe or the halide torch that produce light and heat after energising, the carbon element of heating or halide torch are contained in the air 26 in metal or non-metallic casing 16, and be configured to the out-of-date i.e. heating water of current stay vertical utensil 23, be arranged on outside water tank 12, realize water proof heating, water tank 12 also can preheating simultaneously.

Described instantaneous water heater refers to that water tank capacity is very little, water flows through namely by the electric heater heated, feature is: many electrothermal tubes 13 are housed in water tank and control 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.

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, water flow switch 20, driving switch 21, preheating button 22, the out-of-date i.e. heating water of current stay vertical utensil 23, air 26.

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 horizontal external luminous energy heating of fast heat that water flow switch controls, water flow switch 20, driving switch 21, preheating button 22, 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, determine different electrothermal tube work by driving switch 21; Guan Shui, circuit disconnects automatically.

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