Abstract
The utility provides a flat compound heating tray, comprising a stainless steel tray, aluminum heat conducting board and aluminum heating tube fixed and connected sequentially. The stainless steel tray is made of stainless steel plate. The flat compound heating tray can be applied in electric heaters. The utility model has the following merits: the fabrication and processing process are simple; less consumption of raw materials; low cost; easy to process; less impact on the equipment during the processing process; and working efficiency of the equipment is elevated.
Description
Technical field
The utility model relates to a kind of heat-generating disc, relates in particular to a kind of plane formula composite heating dish.The utility model also relates to a kind of electric heater that uses this heat-generating disc simultaneously.
Background technology
Along with the people's living standard raising, people are also more and more higher to the requirement of household electrical appliance, occurred the various heaters that have heat-generating disc on the market now.The heat-generating disc of Chu Shouing generally comprises the stainless steel heating plate in the market, aluminium heat transfer plate and heating tube.Normally used stainless steel heating plate has two kinds of recessed formula and protruding formulas, stainless steel heating plate as Chinese patent 200320119101.8 liquid heaters has just adopted a kind of recessed formula stainless steel heating plate, but this design exists some shortcomings: owing to need adopt twice above punch forming to corrosion resistant plate, the stretching vestige can be left in its surface, causes difficulty for the back manufacturing procedure; Its stainless crystal structure also can be destroyed, and leaves residual stress, and then operation can not be eliminated this residual stress, and product the phenomenon of getting rusty can occur in use for some time, and stainless steel is fallen short of the reality.
Therefore, it is simple to be badly in need of a kind of processing technology in the market, and reducing the process of processing is the negative effect that product brings, and makes it the heat-generating disc that is difficult for getting rusty.
Summary of the invention
In order to overcome the above-mentioned defective of prior art, it is a kind of simple in structure, easy to process that the purpose of this utility model is to provide, the heat-generating disc of the phenomenon of avoiding occurring in use getting rusty.Another object of the present invention is to provide a kind of and have simple in structurely, be difficult for the electric heater of the heat-generating disc that gets rusty during use.
The utility model provides a kind of plane formula composite heating dish, comprises the stainless steel disc, aluminium heat transfer plate and the aluminium heat-generating pipe that are fixedly connected sequentially, and described stainless steel disc is the corrosion resistant plate on plane.
As a kind of optimal way of the present utility model, the described aluminium heat transfer plate of welding on the surface of described corrosion resistant plate, the bottom surface of described aluminium heat-generating pipe is welded on the described aluminium heat transfer plate.As a kind of optimal way, be connected to screw at described corrosion resistant plate towards a face down bonding of aluminium heat transfer plate, described screw passes the aluminium heat transfer plate, and the aluminium heat transfer plate is fixed on the described corrosion resistant plate.
The utility model also provides a kind of electric heater, and the bottom of described electric heater is provided with foregoing plane formula composite heating dish.
Because adopt above-mentioned technical scheme, heat-generating disc provided by the utility model has following beneficial effect:
1, owing to adopt the plane stainless steel dish, makes that stainless steel disc is one time punching molded in the course of processing, reduced manufacturing procedure, simplified machining process;
2, owing to adopt the plane stainless steel dish, improve the utilance of stainless steel materials, reduced percent defective, thereby saved material, reduced cost;
3, owing to adopt one time punching moldedly, reduce the residual stress in the stainless crystal structure, avoided in use occurring the phenomenon of getting rusty.
Description of drawings
Fig. 1 is the vertical view of heat-generating disc of the present utility model;
Fig. 2 be heat-generating disc of the present utility model A-A to cutaway view;
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
1, corrosion resistant plate; 2, aluminium heat transfer plate; 3, aluminium heat-generating pipe; 4, screw.
Embodiment
Below in conjunction with accompanying drawing embodiment is illustrated:
As depicted in figs. 1 and 2, Planar Compound heat-generating disc provided by the utility model mainly comprises corrosion resistant plate 1, aluminium heat transfer plate 2 and aluminium heat-generating pipe 3.Aluminium heat transfer plate 2 has been welded on the surface of corrosion resistant plate 1, the bottom surface soldering of aluminium heat-generating pipe 3 is on aluminium heat transfer plate 2, center at corrosion resistant plate 1 is connected to screw 4 towards a face down bonding of aluminium heat transfer plate 3, and screw 4 passes the hole that is provided with on the aluminium heat transfer plate 2, is used for fixing corrosion resistant plate 1 and aluminium heat transfer plate 2.The corrosion resistant plate 1 that adopts in the utility model heat-generating disc is one time punching molded plane stainless steel plate, adopt such structural design, reduced the punching press number of times when stainless steel disc is made moulding, thereby simplified machining process, the while economical with materials, also reduce the residual stress in the stainless steel disc, avoided in use occurring the situation of getting rusty.
Heat-generating disc of the present utility model is applied in the electric heater, and wherein heat-generating disc is arranged on the electric heater bottom, is used for heating object.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
