Description

Technical Field

[0001] This utility model belongs to the field of solar hot water tank technology, and in particular relates to a water outlet device at the heating end of a solar heating storage hot water tank. Background Technology

[0002] Solar water heaters primarily rely on collector tubes to convert solar energy into heat energy, heating water from a low temperature to a high temperature. They utilize the principle of hot water rising and cold water sinking to create a micro-circulation, thus achieving the desired hot water temperature for daily life and production. However, in the water tank, cold water is located at the bottom, and hot water at the top. Currently, the outlet pipe is typically located at the bottom of the tank. When hot water is needed, most of the cold water in the bottom of the tank must be drained before hot water can flow out, resulting in water waste. Utility Model Content

[0003] To address the above problems, this utility model provides a water outlet device for the heating end of a solar-powered hot water storage tank.

[0004] This utility model is implemented as follows: A solar-powered hot water storage tank heating end water outlet device is applied to the water tank, which stores water. Multiple water outlets are evenly distributed on the lower part of one side of the water tank, and multiple water inlets are evenly distributed on the side wall of the water tank above the water outlets. Multiple heat collection tubes are evenly arranged inclined upwards on one side of the water tank. The positions of the water outlets, inlets, and heat collection tubes correspond one-to-one. The upper end of each heat collection tube is connected to the water tank, and the water outlets and inlets are located inside the connection between the heat collection tube and the water tank. The water in the heat collection tube absorbs heat, its temperature rises, its specific gravity decreases, and it rises, forming an upward force, thus constituting a thermosiphon system. As the hot water continuously rises and is stored in the upper part of the water tank along the inlets, the cooler water in the water tank flows along the outlets to the heat collection tubes for replenishment. This cycle repeats continuously. A water outlet pipe is provided in the lower middle part of the side, and a water outlet valve is provided on the water outlet pipe. When the water outlet valve is opened, hot water in the water tank flows out along the water outlet pipe. A shell is provided in the water tank. The shell is hollow inside to ensure that the shell floats on the water surface. A block is provided in the middle of the lower end of the shell to limit the position of the water supply branch pipe. Multiple through holes are evenly opened horizontally on the block. The water supply branch pipe is installed through the through holes. The outer diameter of the water supply branch pipe is the same as the inner diameter of the through hole, which ensures a reliable connection between the block and the water supply branch pipe, ensures the stability of the position of the water supply branch pipe, and facilitates disassembly and assembly. One end of the multiple water supply branch pipes is connected to the main water supply pipe at the same time. The other end of the main water supply pipe is connected to the water outlet pipe. When the block is located below the water surface, hot water flows into the water outlet pipe along the water supply branch pipe and the main water supply pipe. When the water outlet valve is opened, hot water flows out along the water outlet pipe.

[0005] Preferably, a water supply pipe is provided on the lower part of the side wall of the water tank to supply water to the water tank. The height of the connection between the water supply pipe and the water tank is lower than the height of the connection between the outlet pipe and the water tank. Cold water enters the water tank from the bottom, avoiding direct disturbance to the hot water in the upper layer, thereby preventing the hot water in the upper layer from cooling down rapidly.

[0006] Preferably, the shell is made of aluminum, which has low density, high strength, corrosion resistance, and can reliably float on the water surface.

[0007] Preferably, the main water supply pipe is made of silicone rubber, which is resistant to high temperature, aging, and corrosion, and has good elasticity, and can be used in the water tank for a long time.

[0008] Preferably, the block and the water supply branch pipe are made of stainless steel, which ensures that the block and the water supply branch pipe can be connected easily and quickly, and that the open end of the water supply branch pipe is underwater. At the same time, it is not easy to rust and has a long service life.

[0009] The beneficial effects of this utility model are: the shell floats on the water surface, and a block is set at the lower end of the shell to limit the position of the water supply branch pipe. One end of the water supply branch pipe is connected to the water outlet pipe through the main water supply pipe. The block is located below the water surface, so hot water flows out along the water supply branch pipe, the main water supply pipe and the water outlet pipe. People can use hot water without draining the cold water at the bottom of the water tank, thus avoiding the waste of water resources. Attached Figure Description

[0013] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0014] like Figure 1 and Figure 2The diagram illustrates a solar-powered hot water storage tank's heating end water outlet device, applied to a water tank 1. The water tank stores water. Multiple water outlets 2 are evenly distributed on the lower part of one side of the water tank 1, and multiple water inlets 3 are evenly distributed on the side wall of the water tank 1 above the water outlets 2. Multiple heat collection tubes 4 are evenly arranged inclined upwards on one side of the water tank 1. The positions of the water outlets 2, water inlets 3, and heat collection tubes 4 correspond one-to-one. The upper end of each heat collection tube 4 is connected to the water tank 1, and the water outlets 2 and water inlets 3 are located inside the connection point between the heat collection tube 4 and the water tank 1. The water inside the heat collection tube 4 absorbs heat, causing its temperature to rise. As the specific gravity decreases and the water rises, it creates an upward force, forming a thermosiphon system. As the hot water continuously rises, it is stored in the upper part of the water tank 1 along the inlet 3. At the same time, the cooler water in the water tank 1 flows along the outlet 2 to the collector pipe 4 for replenishment. This cycle repeats continuously. A water outlet pipe 5 is provided in the lower middle part of one side of the water tank 1. A water outlet valve 6 is provided on the water outlet pipe 5. When the water outlet valve 6 is opened, the hot water in the water tank 1 flows out along the water outlet pipe 5. A shell 7 is provided in the water tank 1. The shell 7 is made of aluminum, which has low density, high strength, and corrosion resistance, and can reliably float on the water surface. The interior of the shell 7 is hollow, ensuring that the shell 7 floats on the water surface. A block 8 is provided at the middle of the lower end of the shell 7 to limit the position of the water supply branch pipe 10. Multiple through holes 9 are evenly opened horizontally on the block 8, and the water supply branch pipe 10 is installed through the through holes 9. The block 8 and the water supply branch pipe 10 are made of stainless steel, which ensures that the block 8 and the water supply branch pipe 10 can be connected easily and quickly, and also ensures that the open end of the water supply branch pipe 10 is below the water surface. At the same time, it is not easy to rust and has a long service life. The outer diameter of the water supply branch pipe 10 is the same as the inner diameter of the through hole 9, which ensures a reliable connection between the block 8 and the water supply branch pipe 10, ensures the stability of the position of the water supply branch pipe 10, and facilitates disassembly and assembly. One end of multiple water supply branch pipes 10 is simultaneously connected to the main water supply pipe 11, and the other end of the main water supply pipe 11 is connected to the outlet pipe 5. The main water supply pipe 11 is made of silicone rubber, which is resistant to high temperature, aging, and corrosion, and has good elasticity, and can be used for a long time in the water tank 1. When the block 8 is below the water surface, hot water flows into the outlet pipe 5 along the water supply branch pipe 10 and the main water supply pipe 11. When the outlet valve 6 is opened, hot water flows out along the outlet pipe 5. A water supply pipe 12 is provided on the lower part of the side wall of the water tank 1. Water is supplied to the water tank 1 through the water supply pipe 12. The height of the connection between the water supply pipe 12 and the water tank 1 is lower than the height of the connection between the outlet pipe 5 and the water tank 1. Cold water enters the water tank 1 from the lower part, avoiding direct disturbance to the hot water in the upper layer, thereby preventing the hot water in the upper layer from cooling down rapidly.

[0015] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
