Description

Water tank of household vacuum pipe solar water heater

The present invention relates to a kind of tank box of household vacuum pipe solar water heater.

In existing household vacuum pipe solar water heater, the tank box shape is very nonstandard, and the casing that has is rule or irregular hexagonal shape, as Fig. 1 or shown in Figure 2.In addition, the passage 1 on the casing and the setting of intake-outlet 2 are also irregular, and passage 1 that has or intake-outlet 2 resemble the product of Lipu, Guangxi solar water heater factory, as shown in Figure 3 and Figure 4 on the casing circumferential location; Do not have a kind of correspondence or symmetric relation, not only influenced the overall appearance of water heater, to all many-sided harmful effects that produces such as technical performance, production I﹠M yet.Above-described being not only at one-pipe Inlet and outlet water casing, the casing of the twin flue Inlet and outlet water of often seeing for us also are so, i.e. the not corresponding relation of water inlet, delivery port 2 and passage 1, as shown in Figure 5 and Figure 6.Lipu, Guangxi solar energy factory produces a kind of casing of twin flue Inlet and outlet water, a little inlet water tank is settled on casing top, built-in ball float, little inlet water tank water inlet 6 and delivery port 2 are all in a side, and the setting of the water inlet 6 on its cylindrical box top and delivery port 2 and passage 1 does not have regularity, be delivery port 2 below the water inlet 6 that has, as shown in Figure 6; Be water inlet 6 below the passage 1 that has, as shown in Figure 7.Above-mentioned casing lacks uniformity, causes some adverse consequences: production technology disunity, drawback such as the materials blanking is lack of standardization, and waste material causes installation procedure loaded down with trivial details easily, and productivity ratio is low.Resemble Fig. 6 and product shown in Figure 7, the system of must overlapping on passage 1 is bent upwards the breather line that height should surpass little water inlet casing, to satisfy the balance needs of casing water level and little inlet water tank retaining peak level.To casing in-built electrical heater how, accomplish how electrical heating performance and water tank Inlet and outlet water performance coordinate the also design of neither one standard in addition.

The purpose of this invention is to provide a kind of design specification, elegant in appearance, and solar water heater casing easy for installation.

Water tank of the present invention is the cylinder type casing, it is characterized in that: the water inlet of described water tank has different pipelines respectively with water outlet, and passage and delivery port are in the same side of water tank, and passage is at water tank upper, delivery port is in the water tank bottom, and water inlet is at the opposite side of casing; The casing water inlet is by being installed in the little inlet water tank control water inlet of casing one side.

Certainly, the water inlet of described water tank and water outlet also can realize by one-pipe, and its passage is in a side of casing, and passage is at the casing topmost, and intake-outlet is at the casing opposite side and in the water tank bottom; The built-in ball float of water tank, intake-outlet have two check valves, and described ball float is connected the common on-off action that rises with check valve.

The present invention can also be further perfect by following scheme:

For twin flue Inlet and outlet water casing, it is characterized in that: described little inlet water tank oneself height is equal to or less than boiler box height (diameter), and in the 2-10cm scope of casing top a ball-cock assembly is housed in little inlet water tank inwall one side, and is connected with water inlet pipe; Its bottom centre position has a delivery port, and the water inlet of this delivery port by bend pipe and heater box links to each other.

For one-pipe Inlet and outlet water casing, it is characterized in that: two check valves that intake-outlet is installed are to adopt to be installed in parallel at casing topmost and foot method arranged side by side, the valve port of two check valves, an end is linked together by inlet and outlet pipe lines, and the other end all is connected on the casing.

No matter twin flue or one-pipe Inlet and outlet water casing, the passage on the casing leads to the outer tube connector of casing and all is being bent upwards from casing 2-10cm place, and it highly is 3-20cm.An electric heater unit can also be installed in water tank in addition, the horizontal level low 2-10cm of the horizontal level at this electric heater unit center than the delivery port that is installed in casing opposite one side (or intake-outlet) center is installed.

Now provide preferred embodiment of the present invention in conjunction with the accompanying drawings:

Fig. 1-Fig. 7 is existing solar water heater casing schematic diagram;

Fig. 8 and Fig. 9 are twin flue Inlet and outlet water box body schematic diagrames of the present invention;

Figure 10 and Figure 11 are one-pipe Inlet and outlet water casing schematic diagrames of the present invention.

Embodiment 1: as Fig. 8, design the cylinder solar water heater water tank of a kind of twin flue (i.e. water inlet and water outlet respectively is independent tubes), passage 1 and delivery port 2 are in the same side of casing, and passage 1 in the above, and water inlet 2 and electric heater unit 3 are at the opposite side of casing; The horizontal level of a little higher than electric heater unit 3 of the horizontal level of delivery port 2 (can certainly not be provided with electric heater unit 3, as shown in Figure 9); During the casing water inlet, by little inlet water tank 4 controls that are installed in casing one side, little inlet water tank 4 inwalls one upper lateral part is equipped with a ball-cock assembly 5; There is a delivery port in little inlet water tank 4 bottom centre, and are connected by the water inlet of bend pipe 6 and casing; The tube connector of passage 1 is bent upwards and highly is 5cm.

Embodiment 2: as shown in figure 10, design the cylinder solar water heater water tank of a kind of one-pipe (promptly water inlet and water outlet are same pipeline), passage 1 is arranged on a side of casing, opposite side at water tank is installed in parallel two check valves, and and intake-outlet 2 connections (can certainly be provided with electric heater unit 3, as shown in figure 11) in water tank; A kind of floater controlled valve device 8 is set in the water tank, when water is full, closes automatically because of ball float 8 risings drive check valve 7; When water, as long as the hot-water switch on the opening conduits relies on the cylinder of pipeline to inhale principle, ball float 8 sinks, and check valve 7 is opened automatically.

Adopt casing of the present invention, have rational in infrastructure, except that the vacuum tube jack, do not open any duct on the casing circumferential location, whole uniformity is good, be convenient to produce, particularly mold is produced two end caps of casing, enhances productivity, and reduces greatly workman's set-up time simultaneously, reduce labour intensity, and for guaranteeing that the user uses hot water performance and convenient maintenance in the future etc. that positive effect is all arranged.
