Abstract

The utility model relates to a water tank of a water heater. The utility model is characterized in that the casing of the water tank is combined by an outer casing and an inner casing forming a plate shape, an interlayer space as a winding pipeline for flowing water is formed between the outer casing and the inner casing, and two ends of the interlayer space are respectively connected with a water inlet pipe and a water outlet pipe. The utility model has the advantages of high heat transferring effect, favorable integrity, simple manufacture procedure, low cost, convenient storage and transportation, etc.

Description

Water-heater water tank

The utility model relates to water heater, specifically is a kind of water-heater water tank.

General common water-heater water tank such as accompanying drawing are shown in Figure 1.Number in the figure 1 is a water tank, the 4th, and heating plate portion, the 3rd, water pipe, the 31, the 32nd, the both ends of water pipe 3.As seen from the figure, water pipe 3 spirals upwards up to heating plate portion 4 around water tank.Existing this class heater water tank mainly has following weak point: the one, because water pipe 3 surfaces are to make by welding to become one with water tank 1, therefore, water pipe 3 is that " line " contacts with 1 in water tank, and its contact area is very narrow and small, so heat-transfer effect is not good.The 2nd, because twining of its pipeline established and to stretch out the water tank root edge very long at water pipe two ends 31,32, so its packing is extremely inconvenient, both accounted for storage and transportation space, the easy again collision deformation in water pipe two ends or the Packaging box body etc. that stabs.

The purpose of this utility model provides a kind of higher heat-transfer effect that has, and can improve the water-heater water tank of above-mentioned packing difficulty.

The utility model of realizing above-mentioned purpose mainly is that tank shell has been done bigger improvement, in the design, this tank shell is combined by shell body that is plate body and inner housing, be formed with between inside and outside housing together as winding pipeline and the mobile mezzanine space that supplies water, the two ends of this road mezzanine space tap into respectively, outlet pipe.

See that by last said water-heater water tank structure because the mezzanine space between the inside and outside housing of composition water tank is the runner of recirculated water, then the most basic advantage of the utility model is the heat transfer efficiency height.Simultaneously, because good integrity of the present utility model can be simplified fabrication schedule, reduce cost.In addition, both do not had being uneven that pipeline etc. causes, do not had the water pipe that protrudes in water tank yet, so the packing of making and accumulating are convenient, safety because of the utility model water tank surface.

Description of drawings:

Fig. 1 is the front view of prior art water-heater water tank.

Fig. 2 is the right side view of the utility model broken section.

Fig. 3 is a front view of the present utility model.

Fig. 4 is a left side view of the present utility model.

Fig. 5 is tank shell and a butt joint schematic diagram thereof in the utility model.

Fig. 6 is the enforcement illustration of another kind of version of the present utility model.

Each label list is shown in the above-mentioned accompanying drawing:

The 1-water tank,

11,13-water pipe,

The 2-shell body,

2A, 2B-plate edge, 2C, 2D-open-work,

The 20-mezzanine space,

The 21-inner housing, 21A, 21B-plate edge.

Embodiment of the present utility model as shown in drawings, the utility model is described in further detail below in conjunction with resistance and embodiment.

Fig. 2, Fig. 3 and Fig. 4 are three-view diagrams of the present utility model, delineate into stereochemical structure of the present utility model.As seen from Figure 2, the utility model tank shell is combined by shell body 2 that is plate body and

inner housing

21, and 21 of shell body 2 and inner housings are formed with the mezzanine space 20 that constitutes water flow passage; The two ends of this flow channel type mezzanine space 20 connect respectively with inlet tube and

outlet tube

11,13.

A kind of version by the utility model tank shell shown in Figure 5 sees that shell body 2 is a frid frame type structure, promptly is formed with the groove of from bottom to top reciprocally advancing continuously together thereon, offers open-

work

2C, 2D at the end of this groove; Inner housing 21 is dull and stereotyped frame type structure; After shell body 2 is fitted on the lateral surface of inner housing 21, then the groove that bloats on the shell body 2 forms the mezzanine space 20 of 21,2 of inside and outside housings, and this mezzanine space 20 (being groove) forms in plate edge 2A, both sides, 2B joint and turns back, and promptly adjacent mezzanine space 20 is that Zigzag type is communicated with.Open-

work

2C, 2D place on the shell body 2 connect with water pipe 11 or 13.One of this

water pipe

11,13 serves as water inlet pipe (as the water pipe 11 above being positioned at), and another then serves as outlet pipe, makes water flow into mezzanine spaces 20 circulations via water pipe 11, after water pipe 13 outflows, or make it mobile in the other direction.20 streams of mezzanine space as water supply.Making of the present utility model is also very convenient, mainly is stamping-out, bending technique, and shell body 2 is bent into identical frame type with inner housing 21, plate edge 21A, the 21B of plate edge 2A, the 2B of shell body 2 and inner housing 21 to after pressing, the cuboid water tank of rule.

Another kind of version by the utility model tank shell shown in Figure 6 sees that its shell body 2 usefulness one straight plate body is bent into, and is formed with together continuous reciprocal groove on inner housing.After shell body 2 was integral with inner housing 21 applyings, this groove promptly constituted the mezzanine space 20 of 21,2 of inside and outside housings, that is constitutes the water flow passage of water tank.Because of shell body in the present embodiment 2 is straight plate faces, so be easier to accumulating.

Claims

1, a kind of water-heater water tank, it is characterized in that tank shell is combined by shell body 2 that is plate body and inner housing 21,21,2 of inside and outside housings are formed with together as winding pipeline and the mobile mezzanine space 20 that supplies water, and the two ends of this road mezzanine space 20 tap into respectively, outlet pipe 11,13.
