Abstract

A water tank for a solar water heater comprises: an outer shell, an insulating layer in the outer shell, an inner container in the insulating layer, and water inlets and outlets; at least two partitions are arranged in the inner container, the partitions divide the inner container into several parts, and the partitions have The opening that connects two adjacent inner tank cavities. The openings of the two adjacent partitions are preferably arranged in a dislocation up and down, and the openings of the partitions in the same cavity as the water inlet hole of the water tank are preferably arranged at a higher position of the partitions. The temperature of the water entering the next cavity is relatively high in the cavity, which is beneficial to keep the water temperature at the water outlet stable.

Description

solar water heater tank

Technical field:

The utility model relates to the technical field of solar water heaters, in particular to a solar water heater water tank.

Background technique:

At present, in the field of pressurized solar water heater water tank technology, when the hot water in the water heater flows out, the water temperature in the whole water tank drops greatly. Chinese patent No. 99229356.1 has proposed a kind of " solar water heater horizontal water tank " for solving this problem. A partition is arranged in the inner tank to divide the inner tank into left and right parts, and a flow guide device is arranged on one side of the partition. This technical scheme can partly solve the problem that the water temperature drops in a large area, but its effect is not very satisfactory. Furthermore, since the flow guiding device is installed on the dividing plate, the structure is complicated and the manufacture is also inconvenient.

Invention content:

In view of the above defects, the inventor proposes a solar water heater water tank with relatively stable outlet water temperature and reasonable structure during use. It includes: the outer shell, the insulation layer in the outer shell, the liner in the heat preservation layer, and the water inlet and outlet; at least two partitions are arranged in the liner, and the partition divides the liner into several parts. Openings through which the inner cavity communicates. When in use, the added cold water lifts the hot water up and enters the next cavity through the opening. The water entering the next cavity mixes with the hot water in this cavity before entering another cavity. Repeating so many times makes the outlet water temperature stable when the outlet of the water heater is in use. Since the inner tank is provided with a plurality of dividing plates, the pressure bearing strength of the inner tank of the water tank can be greatly improved.

In the utility model, the openings of the two adjacent partitions are preferably set up and down in a dislocation manner, and the openings of the partitions with the same cavity as the water inlet hole of the water tank are preferably arranged at a higher position of the partitions. The temperature of the water entering the next cavity in this cavity is relatively high, which is beneficial to keep the water temperature of the water outlet stable.

In the present utility model, the two adjacent partitions can relatively divide the water tank into a diversion chamber and a water holding chamber. The distance between adjacent partitions is preferably relatively large, which is conducive to the installation of heat collecting tubes, and at the same time is conducive to maintaining a stable water temperature at the water outlet.

Description of drawings:

Fig. 1 is a sectional view of the water tank of the present utility model.

Fig. 2 is a schematic diagram of a partition of the present invention.

Detailed ways:

As shown in Figure 1 and Figure 2, a solar water heater water tank includes: a shell 1, an insulation layer 2 in the shell, an inner tank 3 in the insulation layer, a water inlet 4, and a water outlet 5; the inner tank is provided with six partitions Plate 6, the partition divides the inner tank into seven parts, and the partition has an opening 7 connecting two adjacent inner tank cavities. The upper and lower openings of two adjacent partitions are dislocated, and the opening of the partition with the same chamber as the water inlet hole of the water tank is arranged at a higher position of the partition. Two adjacent partitions can relatively divide the water tank into a diversion chamber 8 and a water holding chamber 9, the distance between two adjacent partitions forming the diversion chamber is relatively small, and the distance between two adjacent partitions forming the water containing chamber is relatively large.

As shown by the dotted line in Figure 1, when in use, the added cold water is mixed with the hot water in the first cavity, and then enters the next cavity through the opening and the diversion cavity, and the water that enters the next cavity is mixed with the hot water in the first cavity. The hot water in the cavity is mixed and then enters another cavity, and this is repeated many times, so that the temperature of the water at the outlet of the water tank is stable. At the same time, the pressure bearing strength of the water tank liner can be improved.

Claims (3)
