Abstract

The utility model relates to a dual-purpose stove which is used to heat and cook. The utility model is composed of a shell, a hearth inside the shell and a directly-fired water jacket arranged on the hearth. The technical proposal is that at least a part of the inner surface of the directly-fired water jacket is designed to be bent. For example, the lower part of the inner surface is designed to be bent and the concave groove on the bent surface forms a smoke guiding groove so that the heat adsorption area and the heat efficiency are increased. The bent surface is easy to be processed. The utility model has simple structure and low cost.

Description

The heating-cooking dual-purpose stove

Technical field:

The utility model is a kind of heating-cooking dual-purpose stove.

Background technology:

For making full use of the heat that coal burning produces, many domestic burners have installed the furnace wall water jacket that is welded by metallic plate and the cover of directly heating up water additional in its body of heater.In order to increase endotherm area, the stove and accessory that has has welded many heat absorbing sheets on the inner surface of its cover of directly heating up water.Because heat absorbing sheet is more, thereby welding is also more, thereby the processing of this stove and accessory trouble and complicated.This has also improved its production cost, causes the price of product higher, and it has thermal effect undesirable.

Summary of the invention:

The purpose of this utility model is: design a kind of simple in structure, handling ease, with low cost, heat is imitated higher heating-cooking dual-purpose stove.

The utility model comprise shell and install in the enclosure burner hearth and the cover of directly heating up water of top, its technical scheme at first is that at least a portion of overlapping inner surface with directly heating up water is designed to the bending surface, for example, the bottom of inner surface is designed to the bending surface, bend lip-deep groove and then form smoke guide trough, thereby increase its endotherm area, improve the thermal efficiency, and this bending surface is convenient to processing, thereby has characteristics simple in structure, with low cost.

For increasing endotherm area as far as possible, and make it easy to processing, bending of the present utility model surface adopts the cross section of ledge and smoke guide trough to be trapezoidal version.And smoke guide trough longitudinally shape longitudinally can be straight trough or S shape groove or V-shaped groove or skewed slot or step groove etc.

For adapting to heating and cooking different requirements, the banking fire lid preferably is set convex is installed directly heating up water to put, and have the banking fire lid to cooperate with it the firepower size.The shape of convex and position are general adopts following several structures and above-mentioned banking fire lid is installed: (1) banking fire lid is installed convex and is directly heat up water the laterally prominent muscle at the minimum place of inner surface radial direction size of cover bending of system.At this moment, the diameter of the surperficial the most close center of the inner surface that can make the cover top of directly heating up water and bending is identical to reach maximum endotherm area.(2) banking fire lid is installed the upper surface of convex for the surperficial ledge of bending, the diameter that at this moment requires the banking fire lid greater than the bending surface the most close center internal diameter, less than its apart from diameter of farthest, center when the banking fire lid is installed, to keep ventilating.(3) if smoke guide trough is the step surface that upper diameter is big, lower diameter is little, its step surface also can be used as the banking fire lid convex is installed.

In addition, the cover of directly heating up water of the present utility model availablely has the cast steel of good welds performance and cast copper to make, thereby improves its service life.And when the furnace wall water jacket is arranged in the body of heater, two water jackets can be welded and are connected as a single entity, its concrete structure can be: the upper port of furnace wall water jacket surfaces externally and internally respectively with the lower port welding of the cover surfaces externally and internally of directly heating up water.

The specific embodiment:

Embodiment one:

As shown in Figure 1, 2, 3, present embodiment comprises shell 9, be installed in burner hearth 11 in the shell 9, the furnace wall water jacket 10 between burner hearth 11 and the shell 9 and be positioned at burner hearth 11 and furnace wall water jacket 10 tops and directly heating up water of being connected with furnace wall water jacket 10 overlaps 4, wherein furnace wall water jacket 10 is welded by steel plate, the cover 4 of directly heating up water is made for cast steel, water jacket 10 upper port in furnace wall link to each other by welding respectively with the inside and outside wall of cover 4 lower port of directly heating up water, and both are communicated.Directly the heat up water bottom of cover 4 inner surfaces of present embodiment is made of the plane that is an angle mutually, and forms to outstanding part of central axis direction and the smoke guide trough between them, and it is trapezoidal that the cross section of smoke guide trough and ledge all is.There is horizontal fire sealing cover that prominent muscle is installed in in-plane, and has circular banking fire lid 3 to cooperate with it to the outstanding radial dimension minimum of central axis direction.Its footpath phase size of cover 4 top of directly heating up water is identical with the minimum diameter of locating of its underpart radial dimension.The fire sealing cover 2 that can cooperate with it in addition at the loam cake mouth of present embodiment burner hearth 11.Present embodiment is suitable for briquet.

Embodiment two:

Present embodiment covers 3 positions except that the shape and the banking fire of cover 4 inner surfaces of directly heating up water, and other is identical with embodiment one, no longer repeats here.Shown in Fig. 4,5, the bottom of the inner surface of the cover 4 of directly heating up water of present embodiment is the bending that is made of the plane, constitutes to central shaft outstanding part and the smoke guide trough between them 12, and the cross section that smoke guide trough 12 reaches ledge everywhere all is trapezoidal.The surface of the smoke guide trough 12 radial dimension maximums of present embodiment is the step surface, and the radial dimension on its top is bigger, and the bottom is less, and the step end face of Xing Chenging is that the banking fire lid is installed convex 14 thus, and banking fire lid 3 is positioned on this convex 14.Directly the heat up water radial dimension on top of cover 4 inner surfaces of present embodiment is identical with smoke guide trough 12 radial dimension maximums.Present embodiment is suitable for briquet.

Embodiment three:

Present embodiment covers 3 positions except that the shape and the banking fire of cover 4 inner surfaces of directly heating up water, and other is identical with embodiment one, no longer repeats here.Shown in Fig. 6,7, the bending that the inner surface of the cover 4 of directly heating up water of present embodiment is made of highly consistent plane constitutes to central shaft outstanding part and the smoke guide trough between them 12, and the cross section that smoke guide trough 12 reaches ledge everywhere all is trapezoidal.The banking fire lid 3 of present embodiment is positioned on the upper surface of the cover 4 of directly heating up water, and its size is less than the maximum radial dimension on bending surface, greater than the smallest radial size that bends the surface.The present embodiment diffusing coal that is suitable for burning.
