Abstract

The utility model relates to a water tank for a water heater. The utility model is characterized in that the housing of the water tank for a water heater is composed of two board bodies, a sandwich layer is formed between the two plate bodies, vertically serpentine space which surrounds the water tank is formed in the sandwich layer, and both ends of the space are respectively connected with a heat absorbing piece in a pipeline and a water inlet pipe, so that higher heat efficiency can be obtained. The utility model has the advantages of simple structure, easy manufacture and low cost.

Description

Water tank for water heater

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

At present, a kind of known water-heater water tank is arranged as shown in Figure 1,3 is water tanks among the figure, and 40 is heating plate, the 5th, water pipe, the 51, the 52nd, the two ends of water pipe 5, water pipe 5 is started around dish and the last heating plate 40 that arrives, because of 3 anchor line (string)s of water pipe 5 and water tank contact, contact-making surface is very narrow and small, causes heat transfer efficiency not good; Pipeline twines and establishes and to stretch out water tank long at water pipe two

ends

51,52 again, influence packing and transportation, and the water pipe termination very easily breaks.The water-heater water tank of application number 91225029.1 is to adopt integrated plate body, have on the tank shell around water tank, the flow heated water road that spirals up, though the thermal efficiency is better, make difficult, cost is high.

The purpose of this utility model is that a kind of water-heater water tank on the flow heated water road of sinuous mezzanine space up and down that is made of the two boards body will be provided, and it is simple in structure, thermal efficiency height.

The purpose of this utility model is achieved in that it is made up of connecting leg, pipeline, water inlet pipe, delivery line, heating plate and housing, tank shell is to constitute with two plate bodys, and the formation interlayer, form in the interlayer together and wriggle up and down around the space of water tank, pipeline and the water inlet pipe in the heat absorbing sheet connected at the two ends, space respectively.Tank shell curves rectangle.A slice plate body is a frid 20, on the frid 20 tongue is arranged; Another sheet plate body is an inner housing 22, and the groove of relative tongue is arranged on the inner housing 22, and frid 20 fits tightly on inner housing 22, forms mezzanine space, and mezzanine space forms flow heated water road 21.

Because adopt such scheme, the stream of water-heater water tank is by the formed mezzanine space of two boards body, and is bigger with the water tank contact area, can obtain heat-transfer effect preferably; On making, can not adopt tube material, save processing curved around etc. technology, so easy to manufacture, reduce cost; The water tank surfacing, the aqueduct length at its two ends is concordant with water tank, and integral body is the cube of a Founder, helps packing and transportation.

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

Fig. 1 is known water-heater water tank reference diagram.

Fig. 2 is known water-heater water tank stereogram.

Fig. 3 is the utility model embodiment structural map.

Fig. 4 is the utility model embodiment schematic diagram.

Fig. 5 is the utility model embodiment side view.

Among the figure: 3. water tank, 31. connecting legs, 32. pipelines, 33. water inlet pipes, 34. delivery lines, 22. inner housings, 5. water pipe, 51,52. water pipe two ends, 40. heating plates, 20. frids, 21. mezzanine spaces.

Referring to Fig. 3～5: the utility model is made of two plate bodys, and a slice plate body is a frid 20, and another sheet is an inner housing 22.Frid 20 and on the mezzanine space that wriggles vertically around water tank be stream 21 and inner housing 22.Frid 20 adopts welding manner to fit tightly on inner housing 22, forms a mezzanine space stream 21 by the tongue on groove on this inner housing or the frid 20, and stream 21 is vertically, wriggles around water tank up and down.Pipe fitting 31 is connected the pipeline 32 of mezzanine spaces 21 upper ends to the heat absorbing sheet 40, and the lower end of mezzanine space 21 is water inlet pipe 33 in succession, the terminal delivery line 34 that forms of the pipeline of heat absorbing sheet 40; The length of water inlet pipe 33 and delivery line 34 is concordant with the bottom surface of tank shell, and making this product design is the rectangular body that does not have thin projections.Two long tubes 33,34 are not outstanding, are easy to packing and transportation.

During use, water inlet pipe 33 is communicated with water supply line, delivery line 34 is connected the hot water supply line, then cold water is imported the mezzanine space 21 of frid 20 by water inlet pipe 33, arrive heat absorbing sheet 40 around water tank inner housing 22, after being heated into hot water, being fed to hot water tube system by delivery line 34 again and using.

Claims

1, a kind of water-heater water tank, it is made up of connecting leg, pipeline, water inlet pipe, delivery line, heating plate and housing, it is characterized in that tank shell is to constitute with two plate bodys, and the formation interlayer, form in the interlayer together and wriggle up and down around the space of water tank, pipeline and the water inlet pipe in the heat absorbing sheet connected at the two ends, space respectively.

2, water-heater water tank according to claim 1 is characterized in that tank shell curves rectangle.

3, water-heater water tank according to claim 1 is characterized in that a slice plate body is frid (20), and frid has tongue on (20); Another sheet plate body is inner housing (22), and the groove of relative tongue is arranged on the inner housing (22), and frid (20) fits tightly on inner housing (22), forms mezzanine space, and mezzanine space forms flow heated water road (21).
