Abstract

The utility model relates to a water tank for a storage water heater, comprising an inner bag of the water tank, wherein a cold water intake pipe and a hot water discharge pipe are arranged on the inner bag of the water tank; a water outlet of the cold water intake pipe is arranged on the bottom of the inner bag of the water tank; a water inlet of the hot water discharge pipe is arranged on the top of the inner bag of the water tank; more than a watertight board which are devided into more than two areas are arranged inside the inner bag of the water tank; the watertight boards are arranged between the cold water outlet and the hot water inlet; a water through pipe is arranged on the upper part of each watertight board; a water inlet of the water through pipe is communicated with the front area of the watertight board; and a water outlet of the water through pipe is arranged at the bottom of the rear area of the watertight board, thereby hot water in the front level can be propelled to the next level. In the case that the volume of the water tank and that of the prior water tank are same, the utility model has the advantages of increased water reserve in the inner bag, simple structure, lower cost, improvement of hot water utilization rate, and guarantee that the water temperature in the water tank is unable to drop quickly due to the entrance of cold water.

Description

Storage water heater's water tank

(1) technical field

The utility model relates to a kind of storage water heater's water tank.

(2) background technology

In order to solve the water temperature decline that pressure-bearing water heater causes because of cold water heads into, the existing structure that the water-heater water tank inner bag is made two inner bags, but because the pressure-bearing type inner bag must adopt the sphere end cap, the volume of the single inner-tube structure of volumetric ratio of the two inner-tube structures of the staving of equal length will be little like this, pondage is reduced, the quantity that vacuum tube is installed simultaneously also will reduce, and structure is complicated, relatively waste material.

(3) summary of the invention

It is big that the purpose of this utility model provides a kind of pondage, simple in structure, storage water heater's water tank of material saving.

In order to achieve the above object, the utility model is achieved in that and comprises inner water tank, be provided with cold water inlet and hot water outlet pipe on inner water tank; The delivery port of cold water inlet is positioned at the bottom of inner water tank, and hot water outlet pipe's water inlet is positioned at the top of inner water tank; It is characterized in that: in inner water tank, be provided with the water fender that is divided into zone more than two more than, water fender is between cold water delivery port and hot water water inlet, top at every water fender was provided with water pipe, the water inlet of crossing water pipe communicates with front region, delivery port be positioned at back region below, the hot water of front region can be advanced to back region like this and flow out again.

Of the present utility modelly further be improved to, to outer lug, corresponding inner water tank wall is also outwards recessed in water fender and inner water tank wall junction, and they are by the roll extrusion grooved seal.In inner water tank, be provided with a water fender.The place is provided with the dash box at the cold water delivery port.

The utility model compared with prior art has following advantage:

1, in the identical situation of water tank staving volume, the inner bag pondage increases;

2, simple in structure, cost reduces;

3, improved rate of thermal water utilization, guaranteed that the water temperature in the water tank can not descend because of entering of cold water is fast.

(4) description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A partial enlarged drawing of Fig. 1.

(5) specific embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description:

As shown in Figure 1, it is a kind of storage water heater's water tank, comprises tank shell 5, is located at the heat-insulation layer 4 in the shell 5, is located at the inner water tank 3 in the heat-insulation layer 4.On inner water tank 3, be provided with cold water inlet 6 and hot water outlet pipe 8; The delivery port of cold water inlet 6 is positioned at the bottom of inner water tank 3, is provided with dash box 7 at the delivery port place of cold water inlet 6; Hot water outlet pipe 8 water inlet is positioned at the top of inner water tank 3; In inner water tank 3, be provided with a water fender 1 that is divided into two zones 31,32, water fender 1 is between cold water delivery port and hot water water inlet, be provided with water pipe 2 on the top of water fender 1, the water inlet of crossing water pipe 2 communicates with front region 31, delivery port be positioned at back region 32 below; The cold water delivery port is positioned at front region 31, and the hot water water inlet is positioned at back region 32.During use, enter under the effect of cold water in the inner water tank 3 owing to dash box 7 and hot and cold water difference in specific gravity, cold water can only enter the bottom of water tank front region 31, hot water that then should zone 31 is advanced to back region 32, hot water with 32 upper stratas of back region in the inner water tank flows out through hot water outlet pipe 8 water inlet at last, and the water temperature of outflow is consistent substantially.Water fender 1 and inner water tank 3 wall junctions are to outer lug 11, and corresponding inner water tank 3 walls also concave 33, and they are by the roll extrusion grooved seal.It can do the inner bag of electric heater water tank, also can do the inner bag of solar water heater water tank.
