The specific embodiment
See also Fig. 1 to Fig. 4, the utility model provides a kind of heating apparatus of electric water heater, comprises an inner bag 1, a heating tube group 2 and a cover body 3; Wherein inner bag 1 is a hollow container; Can be upright cylinder, its inside can hold the water of desire heating, inner bag 1 can metal material or non-metallic material process; The material of inner bag 1, shape and structure do not limit, can suitable as required variation.
Inner bag 1 is connected with a water inlet pipe 4 and an outlet pipe 5; Water inlet pipe 4 and outlet pipe 5 can be connected in positions such as inner bag 1 sidewall or bottom; Water inlet pipe 4 and outlet pipe 5 are connected in inner bag 1 sidewall in the present embodiment; And water inlet pipe 4 is positioned at the below of outlet pipe 5, but the position that water inlet pipe 4 and outlet pipe 5 is provided with do not limit, can suitable as required variation.Water inlet pipe 4 and outlet pipe 5 stretch into inner bag 1, and water inlet pipe 4 can be connected in water pipe, so that via in water inlet pipe 4 input cold water to the inner bags 1, and via heating the hot water of accomplishing in the outlet pipe 5 output inner bags 1.The end that water inlet pipe 4 stretches into inner bag 1 is preferably the position that is positioned at inner bag 1 nearly bottom, and the end (upper end) that outlet pipe 5 stretches into inner bag 1 is preferably the position that is positioned at inner bag 1 nearly top.
In addition; Also can further be equipped with heat conduction fin (figure slightly) on heating tube 21 surfaces, pass area, concentrate on heating tube 21 surfaces to avoid high temperature in order to increase heat; Under the prerequisite that does not influence hot transfer efficiency; Through reducing heating tube 21 surface temperatures, reduce the purpose that incrustation scale produces to reach, the efficiency of heating surface is promoted.
In the present embodiment, a horizontal cylinder is roughly formed at cover body 3 bottoms, and heating tube group 2 is located in cover body 3 bottoms; One upright cylinder is formed at cover body 3 tops; Cover body 3 is provided with a guidance part 33 in addition, and guidance part 33 is between cover body 3 bottoms and top, that is guidance part 33 is the upwards taper of convergent; In order to connect the bottom and the top of cover body 3 different sections; Guidance part 33 is between these water inlets 31 and delivery port 32, and guidance part 33 has the function of guiding current, but also can omit as required and in addition.
See also Fig. 5; In water inlet pipe 4 input cold water to the inner bags 1 capable of using; Water in the inner bag 1 can be got in the cover body 3 by the water inlet 31 of cover body 3, so that utilize the water in the heating tube group 2 heating cover bodies 3, the water after 2 heating of heating tube group can flow out to the delivery port 32 that rises by cover body 3 tops.Be the hot water that heating is accomplished in the outlet pipe 5 output inner bags 1 capable of using this moment.
The setting of the utility model through cover body 3 utilizes the principle of natural cooling and heating convection circulation, makes that the delivery ports 32 that rise to waterborne after 2 heating of heating tube group flow out in the cover body 3, makes the output hot water that outlet pipe 5 can be certain.Secondly, the setting of cover body 3 can form the current that nature is stirred, and forced circulation makes whole courage water uniform temperature preferable, and can promote heats.Simultaneously, utilize cold water, heating tube 21 surface temperatures are reduced, reduce the generation of incrustation scale via water inlet 31 IMPULSIVE HEATING pipes 21.
Moreover the utility model cover body 3 can further be provided with and be the upwards guidance part 33 of convergent taper, can be in order to connecting the bottom and the top of cover body 3 different sections, and have the function of guiding current.
Yet the above is merely the preferred embodiment of the utility model; It is not the scope of patent protection that is intended to limit to the utility model; So the equivalence that all utilization the utility model specifications and accompanying drawing content are done changes, and all in like manner all is contained in the rights protection scope of the utility model.
