Abstract

The utility model relates to easy-mounted and simple anticreeper for an electric water heater, which comprises an upper cover and a lower cover and is characterized in that an involute water inlet channel and an involute water outlet channel involuted synchronistically are arranged on an opposite end face on the upper cover and the lower cover, a film with a through hole is clamped between the two opposite end faces on the upper cover and the lower cover, an internal end of the involute water outlet channel of the lower cover is communicated with the water inlet and an external end is communicated with the through hole on the film; the utility model adopts the principle that a water way is disposed long enough in the upper cover and the lower cover to reach the largest resistance.

Description

The electric heater anticreeper

Technical field

The utility model relates to a kind of electric heater anticreeper, particularly a kind of electric heater anticreeper that utilizes the resistance of water as electrocution-proof protection.

Background technology

Among the disclosed Chinese patent bulletin CN2289174Y a kind of " the anticreep spacer assembly of electric heater " disclosed on August 26th, 1998; be that a kind of being applied in prevents the electric heating device electric leakage on the electric heater; the device of protection personal safety; form by the long insulation tube not only having made water service pipe but also made anticreeper; the one root connects the water inlet of heating inner bag; another root connects the delivery port of heating inner bag; utilize the water resistance of running water to make isolated material; the length L of long insulation tube greater than 2125.5 times of endoporus radius r square; even the 220V alternating current of electric heater part directly contacts with heated water; the electric current of delivery port position is guaranteed safety also less than 0.25mA.This anticreeper is because the necessary long enough of insulation tube water pipe so its occupation space is long, is installed inconvenient.

Summary of the invention

The purpose of this utility model is in order to solve existing electric heater with the problem of anticreeper in the installation inconvenience that exists, and a kind of electric heater anticreeper of easy for installation, compact conformation is provided.

The purpose of this utility model is achieved in that a kind of electric heater anticreeper, comprise loam cake and lower cover, it is characterized in that on loam cake and lower cover opposing end faces, being respectively equipped with involute intake chamber and the involute effluent trough of gradually opening synchronously, between the loam cake both ends of the surface relative, accompany the film of band through hole with lower cover, the involute intake chamber of loam cake is inner to communicate with water inlet, the outer end communicates with through hole on the described film, and involute effluent trough the inner of lower cover communicates with delivery port, the outer end communicates with through hole on the described film.Current flow into the through hole of film, enter the outer end of the involute effluent trough of lower cover, the involute effluent trough of flowing through after its inner delivery port that flows into lower cover then in the outer end of involute intake chamber after the water inlet of loam cake enters involute intake chamber the inner of loam cake, the involute intake chamber of flowing through, thus between the delivery port of the water inlet of loam cake and lower cover the sufficiently long protection against electric shock of formation water route; Because the involute intake chamber in loam cake and the lower cover and the gradually degree of driving into of effluent trough are synchronous, so, film can be clamped between loam cake and the lower cover preferably, make the port of involute intake chamber, involute effluent trough sealed.

Owing to adopted technical scheme described in the utility model, to be installed with in loam cake and the lower cover than long water route, its compact conformation, during use, only need this electric heater being installed on the water route respectively and getting final product at electric heater with anticreeper, and long water pipe need be installed, use the utmost point convenient.

Description of drawings

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

Fig. 1 be electric heater described in the utility model with an embodiment of anticreeper three-dimensional exploded view.

Fig. 2 is the stereo amplification figure of the axle side of loam cake among Fig. 1.

Fig. 3 be among Fig. 1 loam cake along the orthographic projection enlarged drawing of the inner.

Fig. 4 be among Fig. 1 lower cover along the orthographic projection enlarged drawing of the inner.

Among the figure 301, water inlet, 31, water inlet pipe, 3, loam cake, 11, outlet pipe, 1, loam cake, 6, right shell, 7, film, 2, lower cover, 21, water inlet pipe, 41, outlet pipe, 401, delivery port, 4, lower cover, 42, involute effluent trough, 40, counterbore, 81, through hole, 8, film, 5, left shell, 30, boss, 32, involute effluent trough, 320, the outer end, 420, the outer end.

The specific embodiment:

See shown in Figure 1, described electric heater anticreeper, comprise loam cake 3 and lower cover 4, present embodiment touches running water pipe when preventing that the user from using electric heater and one group of anticreeper respectively is set on the water-in and water-out passage of electric heater respectively, wherein loam cake 1, film 7 and lower cover 2 constitute one group, loam cake 3, film 8 and lower cover 4 constitute another group, and two groups of anticreepers are installed in left shell 5 and the right shell 6.

Be that example elaborates now with a group of constituting by loam cake 3, film 8 and lower cover 4, see Fig. 1, on the end face of lower cover 4 inboards, have a counterbore 40, be provided with an involute effluent trough 42 in the bottom of counterbore 40, film 8 is put into counterbore 40, the internal diameter of the external diameter of film 8 and counterbore 40 is suitable, and the inner of involute effluent trough 42 and delivery port 401 join, outer end (referring to the outer end among Fig. 4 420) connects the through hole 801 of film 8; The stereogram of loam cake 3 another angles among Fig. 1 is seen Fig. 2, as can be seen from Fig. 2, the end face of loam cake 3 inboards is provided with boss 30, on the plane of boss 30, be provided with involute intake chamber 32, the inner of involute intake chamber 32 taps into the through hole 801 on the film 8 in water 301, outer end 320 map interlinkings 1, also be the both sides that involute intake chamber 32 on loam cake 3 and the lower cover 4 and involute effluent trough 42 lay respectively at film 8, and the internal diameter of the counterbore 40 of the external diameter of the boss 30 of loam cake 3 and lower cover 4 is suitable, and loam cake and lower cover are clamped in the film among Fig. 18 in the counterbore 40 of lower cover.

In conjunction with Fig. 3 and Fig. 4 as seen, involute intake chamber 32 on loam cake 3 and the lower cover 4 and involute effluent trough 42 are gradually opened synchronously, loam cake among Fig. 33 is fastened on the lower cover 4 of Fig. 4, after making boss 30 among Fig. 3 put into the counterbore 40 of Fig. 4, the involute intake chamber 32 of loam cake 3 overlaps with the track of the involute effluent trough 42 of lower cover 4.

The principle of another group anticreeper that is made of loam cake 1, lower cover 2 and film 7 among Fig. 1 no longer describes in detail, on the lower cover 2 is water inlet pipe 21 just, and on the loam cake 1 is outlet pipe 11; The water inlet process of electric heater is as follows: the water on the running water pipe enters between the film 7 of lower cover 2 and then enters between film 7 and the loam cake 1 through water inlet pipe 21, enter inner container of electric water heater through outlet pipe 11 then, hot water in the inner container of electric water heater through involute intake chamber the inner, outer end that the water inlet on the water inlet pipe 31 301 enters loam cake 3 then the through hole on film 8 801 flows into involute effluent trough 42 outer ends that cover down again, enter outlet pipe 41 outflows through involute effluent trough 42 the inners, water outlet 401 again.
