Description

Technical Field

[0001] The utility model relates to the technical field of solar water heaters, in particular to a solar water heater water tank with a water distribution device. Background Art

[0002] Solar water heaters convert sunlight into heat energy, heating water from low temperature to high temperature to meet people's hot water needs in life and production. Solar water heaters are mainly composed of heat collecting tubes, insulated water tanks, brackets and other related accessories. Solar insulated water tanks are generally divided into vertical water tanks and horizontal water tanks. Horizontal water tanks are small in size and occupy little space, and are generally used in households. Vertical water tanks are large in size and have a large hot water storage capacity. They are generally used in places with large water consumption such as hotels or schools.

[0003] The cold water inlet of the currently used vertical insulated water tank is generally set at the lower part of the tank. When replenishing water, a large amount of cold water directly rushes into the tank. The impact force generated will stir the water in the tank. When stirring, the high-temperature hot water on the upper layer will mix with the cold water just added, lowering the temperature of the hot water in the insulated water tank and affecting the user experience. Summary of the invention

[0004] In order to solve the above problems, the utility model provides a solar water heater tank with a water distribution device which can decompose water replenishment pressure and reduce heat loss.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a solar water heater water tank with a water distribution device, comprising a tank body and a water distribution assembly, the top surface of the tank body is provided with an inlet hole, a top cover is provided on the hole, an overflow port is provided on the upper part of the tank body, a circulation inlet is provided on the upper middle part, a circulation outlet is provided below the circulation inlet, a hot water outlet is provided on the tank body opposite to the circulation inlet, a cold water inlet is provided below the hot water outlet, and a sewage outlet is provided at the midpoint of the bottom surface of the tank body.

[0006] The water distribution device includes a main pipe, a branch pipe, an inner water distribution pipe and an outer water distribution pipe. The main pipe is connected to the cold water inlet of the box body. The inner diameter of the branch pipe is smaller than the inner diameter of the main pipe. The branch pipe intersects the main pipe vertically and is connected with the main pipe. The intersection of the main pipe and the branch pipe is located above the center of the bottom surface of the box body.

[0007] The inner water distribution pipe is a circular ring pipe structure, and the inner diameter of its pipe mouth is the same as the inner diameter of the pipe mouth of the branch pipe. A plurality of water distribution holes are opened on the bottom pipe wall of the inner water distribution pipe. The water distribution holes are arranged in a circular array on the bottom surface of the inner water distribution pipe. The center of the circle of the inner water distribution pipe coincides with the intersection of the main pipe and the branch pipe. The pipe body is at the same horizontal position as the main pipe and the branch pipe, and is connected to the two. The inner diameter, structure and installation method of the outer water distribution pipe are the same as those of the inner water distribution pipe, except that its diameter is larger than the diameter of the inner water distribution pipe, and the outer water distribution pipe is sleeved outside the inner water distribution pipe, and is also connected to the main pipe and the branch pipe.

[0008] As an optimization solution for this case, in order to prevent the cold water from directly contacting the hot water at the mouth of the heat collecting tube, causing the heat collecting tube to vibrate or even burst, a guide plate is provided above the water distribution device. The guide plate is a circular plate, and a number of equidistant guide holes are opened on the end face of the guide plate. The outer wall is connected to the inner wall of the box body, and the distance between the bottom surface and the water distribution device is 20-30cm.

[0009] As an optimization solution for this case, in order to improve the stability of the water distribution device in the bottom of the box and reduce the displacement caused by water flow impact, a plurality of clamping support assemblies are arranged under the water distribution device, and the clamping support assemblies include a support seat and a clamping rod. The support seat is connected and fixed to the bottom of the box body, the bottom surface of the clamping rod is fixedly connected to the top surface of the support seat, and a jacket is installed on the top surface, and the various tubes of the water distribution device are clamped and limited by the jacket.

[0010] Beneficial effects: 1. The utility model installs a water distribution device at the cold water inlet of the water tank. When replenishing water, the cold water flows through the main pipe and the branch pipe to buffer the water pressure and then flows out from the water distribution holes of the inner water distribution pipe and the outer water distribution pipe. The water distribution holes are opposite to the bottom of the tank. The replenished cold water will first mix with the warm water on the bottom of the tank, and then flow into the heat collecting tube for heating. It will not spray upward to mix with the hot water in the upper middle part of the tank to lower the hot water temperature, which greatly improves the user experience and reduces the heat loss of hot water.

[0011] ②. By setting a guide plate above the water distribution device, the speed of the supplementary water can be reduced, the mixing time of cold water and warm water can be prolonged, and then the water rises through the guide hole and enters the heat collecting tube through the circulation outlet for heating, so that the cold water will not directly contact the hot water at the mouth of the heat collecting tube. It can effectively prevent the water temperature in the water tank from being high due to the water heater not being used for many days or the light intensity is high. When the water temperature in the heat collecting tube reaches a boiling state, it is easy to cause vibration or even bursting when the cold water directly enters the heat collecting tube, thereby reducing safety hazards and increasing the service life of the heat collecting tube.

[0019] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. The drawings are all in a very simplified form and use inaccurate ratios, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. Example 1

[0020] like Figure 1-2 As shown, this embodiment discloses a solar water heater tank with a water distribution device, which specifically includes a tank body 1 and a water distribution component. Figure 1 It can be seen that an inlet hole 2 is provided on the top surface of the box body 1, a top cover is provided on the hole, an overflow port 3 is provided on the upper part of the box body 1, a circulation inlet 4 is provided on the upper middle part, a circulation outlet 5 is provided below the circulation inlet 4, a hot water outlet 6 is provided on the box body 1 opposite to the circulation inlet 4, a cold water inlet 7 is provided below the hot water outlet 6, and a sewage outlet is provided at the midpoint of the bottom surface of the box body 1.

[0021] See also Figure 1 and Figure 2 The water distribution device includes a main pipe 8, a branch pipe 9, an inner water distribution pipe 10 and an outer water distribution pipe 11. The main pipe 8 is connected to the cold water inlet 7 of the box body 1. The inner diameter of the pipe mouth of the branch pipe 9 is smaller than the inner diameter of the pipe mouth of the main pipe 8. The branch pipe 9 intersects the main pipe 8 vertically and is connected thereto, and the intersection of the main pipe 8 and the branch pipe 9 is located above the center of the bottom surface of the box body 1.

[0022] For specific structure, see Figure 2 The inner water distribution pipe 10 is a circular tube structure, and the inner diameter of its pipe mouth is the same as the inner diameter of the pipe mouth of the branch pipe 9. A plurality of water distribution holes 12 are opened on the bottom pipe wall of the inner water distribution pipe 10. The water distribution holes 12 are arranged in a circular array on the bottom surface of the inner water distribution pipe 10. The center of the circle of the inner water distribution pipe 10 coincides with the intersection of the main pipe 8 and the branch pipe 9. Its pipe body is at the same horizontal position as the main pipe 8 and the branch pipe 9, and is connected to the two. The inner diameter, structure and installation method of the outer water distribution pipe 11 are the same as those of the inner water distribution pipe 10, except that its diameter is larger than the diameter of the inner water distribution pipe 10. The outer water distribution pipe 11 is sleeved outside the inner water distribution pipe 10 and is also connected to the main pipe 8 and the branch pipe 9. Example 2

[0023] like Figure 2-5 The specific structure and implementation method are as shown in Example 1, except that: Figure 3 It can be seen that a guide plate 13 is provided above the water distribution device, see Figure 4, the guide plate 13 is a circular plate, and a plurality of equidistantly arranged guide holes 14 are opened on the end face of the guide plate 13, and its outer wall is connected to the inner wall of the box body 1, and the distance between the bottom surface and the water distribution device is 20-30cm.

[0024] A plurality of clamping support components 15 are arranged below the water distribution device. Figure 5 The clamping support assembly 15 includes a support seat and a clamping rod. The support seat is fixedly connected to the bottom of the box body 1, the bottom surface of the clamping rod is fixedly connected to the top surface of the support seat, and a jacket is installed on the top surface, and the jacket is used to clamp and limit the various pipes of the water distribution device.

[0025] During use, the supplementary water flows into the main pipe 8 from the cold water inlet 7, flows through the branch pipe 9 for buffering and pressure relief, and then flows into the external water distribution pipe 11 and the internal water distribution pipe 10, and then flows out through the water distribution hole 12. Since the water outlet direction of the water distribution hole 12 is opposite to the bottom surface of the box body 1, the water flow pressure is first released downward. At this time, the warm water at the bottom of the cold water fish box body 1 is mixed, and will not come into contact with the hot water floating in the upper middle part of the box body 1, and will not reduce the temperature of the hot water.

[0026] When cold water and warm water are mixed, the guide plate 13 is provided on the top, which reduces the speed of the supplementary water flowing up and prolongs the mixing time. After the mixing is completed, the water flows up through the guide holes 14 of the guide plate 13 to the circulation outlet 5 and enters the heat collecting tube for further heating. At this time, after the cold water is mixed with the warm water, its temperature is increased so that the cold water will not directly contact the hot water at the mouth of the heat collecting tube. This can effectively prevent the water temperature in the water tank from being high due to the water heater not being used for many days or the high light intensity. When the water temperature in the heat collecting tube reaches a boiling state, the cold water is prone to vibration when it directly enters the heat collecting tube, and even causes the tube to burst.

[0027] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
