Abstract

The utility model relates to a water heater, comprising a water sleeve barrel, and the lower part of the outer side of the water sleeve barrel is provided with a water inlet. The utility model is characterized in that a spirally coiled heating pipe is arranged in the heat collecting chamber of the water sleeve barrel, the upper end of the heating pipe is connected with the water storage chamber of the water sleeve barrel, and the lower end of the heating pipe is extended out of the water sleeve barrel. The water heater having short time for heating water and high heat utilization rate is suitable for matching with kitchen ranges having various heat sources in order to provide hot water required by families, units, life, bath, etc.

Description

Water heater

The utility model relates to a kind of water heater.

Use a more general class cooking stove water heater at present, its structure is a cartridge type water jacket, is provided with water inlet and delivery port on water jacket.During use water heater is placed on the cooking stove, the medial surface of a heat accumulating chamber that is enclosed by the cartridge type water jacket is adopted heat, and then the water in the water mantle reservoir is heated.For improving the utilization rate of heat energy, existing a kind of water heater increases to the heat accumulating chamber in the water jacket a plurality of, the heat exchange area when adding hot water with increase.But the increase of heat accumulating chamber number is also given greatly the volume of water jacket reservoir thereupon, because reservoir increase back pondage is bigger, still shows slightly long so add the time of hot water.

The purpose of this utility model is to provide a kind of water heater that the hot water time is short, the heat energy utilization rate is high that adds.

For achieving the above object, the water heater that the utility model provides has a water mantle 2, heat accumulating chamber 9 open at both ends that water mantle 2 is enclosed, one water inlet 1 is arranged at the water mantle 2 outer bottoms of surveying, in the heat accumulating chamber 9 of water mantle 2, be provided with the heating tube 8 of spirality coiling, the reservoir 10 of the upper end of heating tube 8 and water mantle 2 joins, and stretch out outside the water mantle 2 lower end of heating tube 8.

The heating tube 8 of the heat accumulating chamber 9 inside spins coiling of water mantle 2 can increase the heat exchange area when adding hot water greatly, so that the heated time of cold water shortens largely.During use, place this water heater on the cooking stove and make its heat accumulating chamber 9 lower ends uncovered facing to thermal source.Enter to enter in the heating tube 8 after water in the reservoir 10 are heated by water inlet 1 and further be heated again, flow out by the lower end of heating tube 8 then, can be for use.

This water heater is simple and reasonable for structure, and the time that adds hot water is short, heat energy utilization rate height.

Description of drawings:

Fig. 1 is the structure chart of the utility model one embodiment.

Further specify the utility model down in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, water mantle 2 is made by sheet metal.Heating tube 8 is copper pipe or aluminum pipe.Bottom and 2 of water mantles at heating tube 8 are connected with support bar 11, to reinforce heating tube 8.Establish one has to enclose and connects the uncovered chimney 3 in heat accumulating chamber 9 upper ends on the top of water mantle 2, is provided with a reflector 5 that is blocked in heat accumulating chamber 9 uncovered tops in the chimney 3.Reflector 5 adopts sheet metal.Reflector 5 can make by heat accumulating chamber 9 heat energy some return once more, thereby make heat energy obtain utilizing more fully.Be installed with journal stirrup 6 on water mantle 2, chimney 3 connects with journal stirrup 6 by screw 7.Reflector 5 is loaded on the chimney 3 by connecting rod 4.

This water heater is fit to the cooking stove adapted with various thermals source, with required hot water such as provide family, unit life or have a bath.
