Description

The electric heater of the quick-heating type alumina ceramic heating body heating that water flow switch controls

Technical field

The utility model relates to the electric heater of the quick-heating type alumina ceramic heating body heating that water flow switch controls.

Background technology

Patent application publication CN104236106A discloses " electric heater that water flow switch controls ", although relate generally to storage-type electric water heater also relate to instantaneous water heater, statement imperfection, still have outside deficiency, present patent application provides a kind of new structure.

Utility model content

The utility model improves on the basis of CN104236106A, the electric heater that the quick-heating type alumina ceramic heating body controlled for water flow switch after improving heats, by water flow switch 20, water tank 12, aluminium oxide heater 13, water inlet pipe 14, outlet pipe 15, shell 17, mechanical water resistance 22, formation such as tank pressure control assembly 23 grade; Described water flow switch 20 is made up of the pushing pin 11 of main body 1, cover plate 2, seal 3 and impeller 4, spring or spring leaf 5, installation cover plate 6, microswitch 7, stationary contact 8, movable contact 9, terminal 10, microswitch, 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 water tank 12 metal material or nonmetallic materials injection moulding or blowing make;

Aluminium oxide heater 13 is that heating wire aluminium oxide ceramics wraps up completely, and makes hollow circle or flat through high temperature sintering, is arranged in water tank, heats the water flow through;

Described mechanical water resistance 22 refers to water inlet pipe 14, outlet pipe 15, makes of the non-metallic pipe of length >200mm;

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.

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.

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, and adopt aluminium oxide ceramics calandria when water is closed, safe especially.

Accompanying drawing explanation

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, cover plate 6 is installed, microswitch 7, stationary contact 8, movable contact 9, terminal 10, the pushing pin 11 of microswitch, water tank 12, alumina ceramic heating body also claim electrothermal tube 13, water inlet pipe 14, outlet pipe 15, shell 17, water to chew 18, water flow switch 20, driving switch 21, mechanical water resistance 22, tank pressure control assembly 23, preheating switch 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-heating type alumina ceramic heating body 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, and 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, and when discharging water, water flow switch 20 makes microswitch pushing pin 11, promotes movable contact 9 and contacts with stationary contact 8, now, determine that different electrothermal tubes is worked by driving switch 21; Guan Shui, circuit disconnects automatically.

Described water tank 12 metal or nonmetallic materials injection moulding or blowing make;

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