Description
Technical field
The utility model relates to gas heater, and specifically, the utility model relates to a kind of fan of gas water heater spiral case.
Background technology
Currently available technology, fan of gas water heater spiral case adopts welding manner to be fixedly connected with, solder joint is many, affects attractive in appearance, and the perishable damage of weld, publication number is the blower fan that patent discloses a kind of gas heater of 202937475U, patent refer to a kind of non-solder spiral case, but the mode of being fixedly connected with that this utility model patent adopts, and product processing technique is complicated, moulds of industrial equipment cost is higher, and production efficiency is lower.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of fan of gas water heater spiral case, and this kind of fan of gas water heater is simple with spiral case Product processing, can reduce moulds of industrial equipment cost, enhance productivity.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of fan of gas water heater spiral case, comprise spiral case header board, spiral case air duct board, plate after spiral case, outlet flue connecting plate and smoke outlet flue, described spiral case header board is provided with into mouth, spiral case header board, spiral case air duct board, after spiral case, plate surrounds outlet flue, outlet flue connecting plate and smoke outlet flue are positioned at above outlet flue, described spiral case air duct board and spiral case header board, after spiral case, the both sides of plate contact are arranged at intervals with some spiral case air duct board extensions respectively, described spiral case header board is provided with the spiral case header board elongated hole that to adapt with spiral case air duct board extension, after described spiral case, plate is provided with plate elongated hole after the spiral case that to adapt with spiral case air duct board extension, described spiral case air duct board extension tightens up through the bending of spiral case header board elongated hole, described spiral case air duct board extension tightens up through plate elongated hole bending after spiral case.
Described spiral case header board periphery is provided with three uniform mounting ears, and each mounting ear all has Bolt through holes, and described spiral case header board is also provided with an installing hole with screw fastening.
The curve of described spiral case air duct board is spiral of Archimedes.It is very smooth that flue gas operates in spiral case.
The utility model fan of gas water heater spiral case adopts technique scheme, not only overcomes pad defect, and resistance to oil smoke corrosion, extend service life, and Product processing is simple, can reduce moulds of industrial equipment cost, enhance productivity effectively.
Accompanying drawing explanation
Fig. 1 is the graphics of the utility model fan of gas water heater spiral case;
Fig. 2 is the three-dimensional, exploded view before the utility model fan of gas water heater spiral case combination forming;
Mark in above-mentioned figure is: 1, spiral case header board; 2, plate after spiral case; 3, spiral case air duct board; 4, outlet flue connecting plate; 5, smoke outlet flue; 6, mouth is entered; 7, outlet flue; 11, spiral case header board elongated hole; 12, mounting ear; 13, Bolt through holes; 14, installing hole; 21, plate elongated hole after spiral case; 31, spiral case air duct board extension.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As Fig. 1, shown in Fig. 2, a kind of fan of gas water heater spiral case of the utility model, comprise spiral case header board 1, plate 2 after spiral case, spiral case air duct board 3, outlet flue connecting plate 4, smoke outlet flue 5, described spiral case header board is provided with into mouth 6, the upper end of spiral case header board 1, plate 2 after spiral case, the upper end of spiral case air duct board 3 surrounds outlet flue 7, outlet flue connecting plate fills 4 at outlet flue 7 place, smoke outlet flue 5 is contained on outlet flue connecting plate 4, described spiral case air duct board 3 and spiral case header board 1, the both sides that after spiral case, plate 2 contacts are arranged at intervals with some spiral case air duct board extensions 31, described spiral case header board 1 and spiral case air duct board extension 31 correspondence position arrange the spiral case header board elongated hole 11 being used for extension and passing, after described spiral case, plate 2 and spiral case air duct board extension 31 correspondence position arrange plate elongated hole 21 after spiral case, spiral case air duct board extension 31 is through spiral case header board elongated hole 11, bending after plate elongated hole 21 after spiral case, by spiral case air duct board 3, spiral case header board 1, after spiral case, plate 2 is affixed integral.
Described spiral case header board 1 is provided with three mounting ears 12, each mounting ear 12 all there is Bolt through holes 13, described spiral case header board 1 is also provided with an installing hole 14 with screw fastening, during use, each Bolt through holes 13 and installing hole 14 all have a screw to pass, thus are fixed on by spiral case on collection cigarette air channel.The curve of spiral case air duct board 3 is spiral of Archimedes, and it is very smooth that flue gas operates in spiral case.
The utility model fan of gas water heater spiral case adopts such structure, overcome the deficiency of weld perishable damage when welding manner makes, resistance to oil smoke corrosion effectively, extend service life, blanking and assembling moulds of industrial equipment used make simple and quality and easily control, product quality is ensured, can reduce moulds of industrial equipment cost, enhance productivity.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out, all within protection domain of the present utility model.
