Description
Technical field
The utility model relates to electric heater, the instant electric water heater that particularly a kind of employing thermal sensitive ceramics (PTC) is made.
Background technology
Existing electric heater is divided into two kinds of storage type electric heater and instant electric water heaters.The characteristics of storage type electric heater maximum are can store heat, and it can utilize the electric energy in night to heat at leisure, and its electrical power designs lessly, but its volume is bigger, and the thermal efficiency is not high.
The instant electric water heater generally adopts heating wire as heater element, and its heater element is divided into two kinds of naked formula heating and flush type heatings by structure, at present with flush type heating in the majority as heating element heater.Adopt in the fast water heater of naked formula heating, electric current flow through not with the water insulation, directly be immersed in heater element in the water, have that thermal inertia is little, heating rapidly, can guarantee to open the characteristics that hot water is provided behind the water valve at short notice.Adopt the fast water heater of flush type heating, its heater element is generally tubular electrothermal element, its structure is the heating made from a copper pipe or stainless steel tube, the in-built electrical heated filament, embedding magnesia or quartz sand again, form through draw moulding, heating wire and water insulation have safety, well-set characteristics.
Above-mentioned two kinds of heating structures are used for the instant electric water heater at present in a large number, but exist following shortcoming simultaneously:
1. owing to be the common electrical thermal element, do not have temp autocontrolled function, therefore do not allow empty the burning, have in water under the situation of air pocket, cause the heating wire dehydration easily, heating wire can blow, and causes heater to damage.In addition, to burn easily also be the problem of a long-term puzzlement to electrothermal tube.
2. for the water heater of flush type heating, behind the heating wire heating power, heat is delivered in the water through stainless steel tube through the peromag insulating barrier again, because of there are certain thermal resistance in magnesia and stainless steel, so that heat is transmitted is slower, has influenced electrothermal calefactive rate.
3. adopt the water heater of naked formula heating, its water route and circuit are indiscrete, when water heater working, most of electric current generates heat through heating wire, because water is not insulator, there is certain distributed resistance in water, therefore has certain distributed current in water.When water flows, electric current in the water will be taken out of, form the leakage of electricity, so general being equipped with in the cross section of water heater delivery port with what wire netting was made caught electrical network, but after long-term the use, incrustation scale or other foreign material can be adsorbed on the wire netting surface, and easy like this making caught the electrical network inefficacy, its reliability is relatively poor, exists potential safety hazard in the use.
4. adopt the instant electric water heater, certain restriction is arranged on structural design.For reducing the length of air pocket, structurally certain aisle spare to be arranged.For preventing to produce leakage current, enough non-thermals treatment zone to be arranged also.Therefore its volume is bigger, and inconvenience is installed, and the thermal efficiency is not high yet.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, problems such as task of the present utility model provides a kind of new Instant heating type thermal sensitive ceramics (PTC) electric heater, and it has solved, and the existing heating of existing instant electric water heater is perishable, volume is big, electrothermal calefactive rate is slow, the thermal efficiency is not high.
The technical solution of the utility model is as follows:
A kind of Instant heating type thermal sensitive ceramics electric heater; it comprises water pipe body and the electric heating element that has water inlet and delivery port; described electric heating element comprises the thermal sensitive ceramics element; parallel metal sheet in the installing of two sides of thermal sensitive ceramics element; and the heat conductive insulating potsherd of installing respectively in the outside of two parallel metal sheets; electric heating element is placed in the water pipe body; the thermal sensitive ceramics element is connected to and leads to the external lead-in wire of water pipe; this lead-in wire both was connected with the terminals of parallel metal sheet, and power supply is inserted as power line in the back of connecting with thermal protector again.
The utility model is that a kind of water flows through the Instant heating type thermal sensitive ceramics electric heater that is promptly heated rapidly, have temp autocontrolled, heating rapidly, the thermal efficiency is high, safe and reliable, volume is little, advantage such as easy to install, be mainly used in shower and provide flushing with hot water and the various occasion that needs liquid to heat.
The utility model adopts novel PTC thermal sensitive ceramics as heater element.Thermal sensitive ceramics element heating rapidly and reach after the curie point can automatic constant-temperature, in use need not install thermostat additional, can not be damaged under long-time empty burning state, also can not be damaged under the long-time overvoltage of power supply, undervoltage condition.Because the power of thermal sensitive ceramics element depends on radiating condition, when low or flow was big in water temperature, power can become big automatically, and at water temperature height or flow hour, power is corresponding to be reduced, so it has the automatic regulatory function of certain water temperature.The thermal sensitive ceramics element is low-resistance at normal temperatures, is switching on moment, and its percussion power is bigger, therefore can make the heater transient heating, can produce hot water in the shortest time.
The surface temperature of the utility model under in working order is lower, approaches water temperature, and She Ji volume is also less simultaneously, makes thermal losses reduce to minimum.Because water route and circuit separately structurally do not need the so-called aisle spare and the non-thermal treatment zone, and be more convenient in the design, safer on the performance.
