Abstract

The utility model relates to an external heating device for a hot water drum of a drinking water apparatus, which is made of thinner metal shapes. A heating pipe is arranged in a hole of a heating ring, a nichrome wire is arranged in the heating pipe, both ends of the heating ring are bent into elbows for positioning, and each elbow is provided with at least one positioning hole. The heating device better reserves the use functions and the advantages of the prior art and simultaneously has the advantages of simple structure, tight application of the internal surface of the heating ring and the external surface of the hot water drum, favorable heat transferring effect, easy manufacturing, easy assembly, material saving, low manufacturing cost, etc. The utility model better overcomes the defects of the prior art.

Description

A kind of novel water dispenser hot water barrel uses outer heater

The utility model relates to a kind of special feature of water dispenser, refers to that specifically a kind of novel water dispenser hot water barrel uses outer heater.

No matter existing water dispenser is single hot type or ice hot type, is provided with the hot water barrel all essentially, and produces hot water by Electric heating.The Electric heating that existing water dispenser hot water barrel is adopted, heating and two kinds of forms of outer heating in generally can being divided into.In external heating mode, traditional water dispenser hot water barrel all adopts the outer heater of jacket type, should outer heater be that shape processes, two heating wire devices are in the pore of heating collar, adopt this mode, because the heating collar that adopted is thicker and adopt two heat-generating pipes, be difficult to man-hour make itself and hot water barrel's outer surface to reach to fit tightly adding, thereby cause its heat-transfer effect relatively poor, and it is comparatively complicated to exist locate mode and assembly structure, simultaneously owing to adopted two heat-generating pipes, thereby also cause the waste of material, increased the manufacturing cost of water dispenser.

The purpose of this utility model just is to provide a kind of novel water dispenser hot water barrel to use outer heater, with the heating collar that approaches by its single-shot heat pipe structure and wall thickness, make it in function of use that keeps prior art preferably and advantage, have also that simple in structure, heating collar inner surface and hot water barrel's outer surface are fitted closely, heat-transfer effect is good, be easy to processing and assembling and save material, reduce manufacture cost and other advantages, overcome the deficiencies in the prior art preferably.

The purpose of this utility model realizes in the following manner: a kind of novel water dispenser hot water barrel uses outer heater, mainly form by heating collar and heat-generating pipe, it is characterized in that above-mentioned heating collar is to adopt the thin shape of wall thickness to process, in the hole of this heating collar heat-generating pipe is arranged, nickel filament is contained in this heat-generating pipe, be bent to the elbow that is used to locate at the two ends of above-mentioned heating collar, at least correspondingly have a locating hole on each elbow.

Adopt a kind of novel water dispenser hot water barrel of the present utility model to use outer heater, owing to adopted the thin heating collar of single-shot heat pipe structure and wall thickness, thereby make it in function of use that keeps prior art preferably and advantage, have also that simple in structure, heating collar inner surface and hot water barrel's outer surface are fitted closely, heat-transfer effect is good, be easy to processing and assembling and save material, reduce manufacture cost and other advantages, overcome the deficiencies in the prior art preferably.

Description of drawings:

Accompanying drawing is a kind of example structure schematic diagram of the present utility model.

Wherein: 1-heating collar, 2-heat-generating pipe, 3-nickel filament, 4-elbow, 5-locating hole.

Below in conjunction with drawings and Examples the utility model is further described.

As shown in the figure, a kind of novel water dispenser hot water barrel uses outer heater, mainly form by heating collar 1 and heat-generating pipe 2, it is characterized in that above-mentioned heating collar 1 is to adopt the thin shape of wall thickness to process, heat-generating pipe 2 is housed in the hole of this heating collar 1, nickel filament 3 devices are bent to the elbow 4 that is used to locate at the two ends of above-mentioned heating collar 1 in this heat-generating pipe 2, at least correspondingly have a locating hole 5 on each elbow 4.

In an embodiment, the shape that above-mentioned heating collar 1 is adopted, be to bend by the sheet metal processing that has single pore to form, shape that it bends and hot water barrel's appearance match, heat-generating pipe 2 is in the single hole of heating collar 1, have two locating holes 5 on the elbow 4 at its two ends, heating collar closely is fixed on hot water barrel's outer surface by set screw.Because the shape that above-mentioned heating collar adopted is thinner, thereby when bending, processing is easier to moulding, thereby guarantee fitting tightly between itself and the hot water barrel preferably, its two ends also can process the location elbow easily simultaneously, and needn't set the position device in addition, thus simplify the structure preferably, reduced the consumption of metal material, reduce manufacturing cost, reached the purpose of this utility model.
