Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As illustrated in fig. 1 and 2, structure of the present invention is made up of inner bag 01, combustion chamber 02 and burner 03 3 part, wherein, it is a cylindrical shell 011 in the periphery of inner bag 01, the two ends up and down of cylindrical shell 011 are equipped with salient mounting end socket 012 and recessed dress end socket 013 respectively, and a smoke pipe 014 is housed between salient mounting end socket 012 and recessed dress end socket 013.Combustion chamber 02 is placed in below recessed dress end socket 013, and the lower surface of recessed dress end socket 013 is welded with some welding screws 0131 (as shown in Figure 2), and burner 03 is installed in combustion chamber 02.
Further, the lower surface concavely curved surface of recessed dress end socket 013, can increase the area of heat-exchange surface like this.
Further, inner bag 01 is in cylindric.
Preferably, combustion chamber 02 can be closed by coaming plate, water-collecting tray, fire door and recessed dress end socket and form, and water-collecting tray is in the form of annular discs, and is positioned at the bottom of combustion chamber 02, and combustion chamber 02 is divided into upper and lower two parts space; Wherein, the bottom of coaming plate along the circumferential direction has some coaming plate passages; The side of coaming plate is provided with a combustion chamber openings, and fire door is arranged in combustion chamber openings; Water-collecting tray has the water-collecting tray passage of some rounded distributions; Burner 02 is arranged on water-collecting tray, and the inlet end of burner 02 comprises an induction tunnel, and its ejecting port successively through combustion chamber openings and fire door, and is put the outside stayed in combustion chamber 02 by induction tunnel.
Composition graphs 3 operation principle of the present invention is as follows:
After combustion gas is lighted by the burner 03 in combustion chamber 02, the high-temperature flue gas that burning produces and recessed dress end socket 013, after smoke pipe 014 contacts, upwards discharge from smoke pipe outlet, as shown in flue gas circuit 04, flue gas to transfer heat in inner bag while water storage, temperature also declines gradually, also reduce gradually with the temperature difference of water storage in inner bag, the heat-transfer surface place heat exchange efficiency that the temperature difference is less is lower, therefore, for the volumetric gas water heater of described structure, below the recessed dress end socket 013 in the place that heat exchange efficiency is the highest, lower surface due to recessed dress end socket 013 is welded with multiple welding screw 0131, except the lower surface of recessed dress end socket 013 and the inner surface of smoke pipe 014, the thread surface of welding screw 0131 also becomes heat exchange surface, the water storage that its heat accepted also can will be passed to by recessed dress end socket 013 in inner bag, and thread surface is much bigger compared with smooth surface area, add the quantity increasing welding screw 0131, this is just equivalent to considerably increase heating surface area to recessed dress end socket 013 place that heat exchange efficiency is the highest, thus better can improve exchange capability of heat, in addition, welding screw 0131 is all welded on the lower surface of recessed dress end socket 013, this does not just need on recessed dress end socket 013, to increase perforate welding as Multi exhaust design.Compared with promoting the scheme of exchange capability of heat with increase smoke pipe quantity, this programme decreases weld seam quantity, also reduces the risk of inner bag weld leakage, is also more convenient to weld joint air-tight inspection.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
