The utility model relates to home-use article or the lavatory Assisted Facilty in the equipment, is a kind of syringe and auxiliary equipment thereof, specifically, is a kind of shower set; The utility model also relates to the heater that is specially adapted for the immersion heating in the electroheat technology, specifically, relates to fixedly-mounted immersion calandria.

Existing water heater can be divided into gas heater, electric heater.General electric heater power consumption is big, and has safety issue, and therefore, electric heater is welcome not as gas heater at present.

The purpose of this utility model provides a kind of economize on electricity, safety, energy-saving water heater simple in structure, that cost is low.

Technical solution of the present utility model is: a kind of energy-saving water heater, a housing is arranged, and reservoir is arranged in the housing, the PTC heater is housed in the reservoir, reservoir has water inlet pipe and water outlet pipe and housing to be interlinked to the outside, and on the hydraulic pipeline outside the housing water valve is housed.

Reservoir in the utility model is divided into preheating cavity, heating chamber, PTC heater and is contained between two chambers, two heating surfaces of PTC heater are each positioned in the chamber, preheating cavity is connected to water inlet pipe, and heating chamber is connected to outlet pipe, is connected to communicating pipe between preheating cavity and heating chamber.Certainly, reservoir also can adopt other suitable construction, corresponding other the suitable installation forms that also can adopt of PTC heater.

PTC heater in the utility model comprises and is clipped in two PTC sheet groups between metallic plate that first metallic plate outside of PTC sheet group one side is a heating chamber; Second metallic plate of PTC sheet group opposite side is covered with one deck mica sheet outward, and one the 3rd metallic plate is posted in the mica sheet outside, and the 3rd metallic plate outside is a preheating cavity, and first and second metallic plate respectively has a link of power line.Certainly, the PTC heater also can adopt other suitable versions.

Be connected to dial type piezoelectricity change-over switch on the inlet pipeline in the utility model.Certainly, also can not connect or connect other suitable mechanism.

First metallic plate in the utility model is connected to the zero-power line terminals, and second metallic plate is connected to the power firestreak terminals.

Housing in the utility model adopts plastics system.Certainly, also can adopt other suitable materials to make.

Comprise a hollow housing in the dial type piezoelectricity change-over switch in the utility model, a perforate of joining with exterior line is arranged on the housing, the rubber membrane that one one side band metal spring leaf is arranged in the housing, there are two electrode contacts the housing inboard relative with metal spring leaf, and prevention cover is equipped with on housing top.

The utility model has the advantages that: thermal efficiency height, the electrical power of general water heater is more than 1000 watts, and the utility model has only 400-600 watt.5 kilograms of running water were switched on 0.5 hour, and temperature rise can reach more than 50 ℃, and the power consumption expense during use is more much lower than general electrothermal water heater.Security is good, and PTC heater of the present utility model has adopted comparatively reasonable structure form.Security is fine, the phenomenon of can not getting an electric shock.Simple in structure, cost is low, and price is lower than general water heater, easily adopts for domestic consumer.Purposes is wide, is applicable to the haircut hair washing, and family has a bath and washs with occasions such as hot water.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the structural representation of a kind of energy-saving water heater of the present utility model.

A kind of electric circuit diagram of Fig. 2 for being adopted in the utility model.

Fig. 3 is a dial type Piezoelectric switches structural representation.

Fig. 1 has described an embodiment of the present utility model.Constitute a hollow container by plastic casing 1, (also can at other correct positions) be installed with a PTC heater that is made of PTC sheet group 2, metal heater plate (can adopt materials such as aluminium) 3 and 4, rubber spacer 5 and 6, mica sheet 7, aluminium sheet 8 in the middle part of container, and the PTC heater will be divided into two chambers in the housing 1; Superposed heating chamber, be positioned at the preheating cavity of bottom, be connected with cold water inlet 11 on the preheating cavity, heating chamber is connected with hot outlet pipe 10, be connected with communicating pipe 12 between heating chamber and the preheating cavity, on outlet pipe, be connected to outlet valve 13, be connected to water intaking valve 14 on the water inlet pipe, 13 of water intaking valve 14 and outlet valves also have pipeline connection, are connected to delivery port at the mid portion of this pipeline.On water inlet pipe, be connected to dial type piezoelectricity change-over switch 9.

The operation principle of the foregoing description is: constitute heater by a series of PTC ceramic bodies.One side of heater is used for preheating water, and opposite side is used for the water through preheating is further heated.By having the gauge tap (two grades) of piezoelectricity conversion, realize the temperature control of hot water, promptly from the temperature to heat, also play the control of heat time heating time, promptly from growing to weak point.The flow that the actual also available Cold-hot water valve of water temperature that uses is controlled cool hot water is regulated.The effect of piezoelectricity conversion is: have only after running water is full of whole chamber, just can connect with the mains in order to avoid energising heating and scorch plastic casing during lack of water.

The foregoing description has good protection against electric shock measure: the heating plate that is positioned at heating chamber (directly being communicated with an outlet pipe) side of PTC heater only connects zero-power line, and the line of not starting to exchange fire makes water be in zero potential.Starting to exchange fire is lined with one deck mica-sheet insulation layer between the heating plate of line end and preheating cavity, thereby makes the hot water can be not charged.Also utilize wire-mesh screen to do in addition and catch electrical network and ground connection, wire-mesh screen can be contained in the place from the about 10mm of hot water outlet.

Fig. 2 has described the adoptable electric wiring of the utility model.Comprise piezoelectricity change-over switch and PTC heater in the circuit, its operation principle is simpler, no longer narrates at this.

Fig. 3 has described adoptable a kind of dial type Piezoelectric switches in the utility model.Comprise a plastic chamber shell 20, there is a perforate 32 that taps into water lines shell 20 lower ends in chamber, the rubber membrane 31 of the rubber of a band reed 22 is housed in the chamber shell 20, the electrode that inboard, chamber shell 20 upper end has two screws 29 to constitute, rubber membrane 31 relies on screw 24 fixing, two switch stators 25, switch moving plate 26, and bakelite ring 28 etc. are housed outside chamber shell 20 upper ends, and a dial type loam cake 30 relies on screws 27 to be contained on the chamber shell 20.

The utility model also can adopt some other embodiment, as the temperature indicating device (can use for reference prior art) that adds common form on housing.Or add that electric leakage shows or earth leakage protective device (also can use for reference prior art).Certainly, also can add other feasible and suitable mechanism or devices.
