[0002] In the scene of city central heating and boiler hot water supply, in order to stably supply cold and hot water meeting temperature requirements to users, it is necessary to avoid temperature loss of control caused by mixing of cold and hot fluids, and generally two water storage tanks are used, one for storing hot water and one for storing cold water, and a water distributor is generally used to uniformly distribute water to ensure the heating / cooling scene.

[0003] The traditional heating / cooling system generally uses two independent tanks to store cold and hot water respectively to prevent heat mixing. This double-tank design not only occupies a large space, but also generates high energy consumption due to independent operation, which is not conducive to the improvement of space utilization and system economy. At the same time, the water distributor in the single tank is not uniform and easy to produce violent turbulence, which destroys the stratification interface of cold and hot water, causing mixing of cold and hot fluids, resulting in temperature fluctuations of terminal water, and unable to stably maintain the characteristics of low temperature of cold water and high temperature of hot water.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] As attached Figures 1-9 The circular pipe slotted water distributor shown includes a hot water inlet pipe 1 and a cold water inlet pipe 2 for water inlet. A cold water distribution mechanism is provided on the outside of the cold water inlet pipe 2, and a hot water distribution mechanism is provided at the bottom of the hot water inlet pipe 1. The cold water distribution mechanism includes a fixed shell 3, which is fixedly sleeved on the outside of the cold water inlet pipe 2. A diversion plate 4 is fixedly installed on the top of the fixed shell 3. The diversion plate 4 is fixedly sleeved on the outside of the cold water inlet pipe 2. Multiple first diversion pipes 5 are evenly distributed on the outside of the cold water inlet pipe 2. A strip-shaped slit 6 is opened on the bottom surface of each of the multiple first diversion pipes 5. A diversion groove 7 is opened on the top surface of the diversion plate 4. The diversion groove 7 is located between the first diversion pipes 5 and the diversion plate 4. The hot water distribution mechanism includes a rotating inlet pipe 8, which is installed at the bottom of the hot water inlet pipe 1. Multiple second branch pipes 9 are evenly distributed on the outside of the rotating inlet pipe 8. One end of the second branch pipe 9 is fixedly connected to an inclined guide pipe 10. An arc-shaped guide slit 11 is opened on one side surface of the inclined guide pipe 10. A fixed shaft 12 is fixedly connected to the bottom of the inner wall of the inclined guide pipe 10. Multiple spiral guide plates 13 are evenly fixed on the outside of the fixed shaft 12. A spring 14 is fixedly connected to one side of the inner wall of the arc-shaped guide slit 11. An elastic baffle 15 for blocking the flow is fixedly connected to one end of the spring 14. A rotating mechanism is provided between the hot water inlet pipe 1 and the rotating inlet pipe 8.

[0028] As attached Figure 1 , 2 As shown in Figure 8, a first connecting rod 16 is fixedly connected to the top of the cold water inlet pipe 2, and a fixing plate 17 is fixedly connected to the top of the first connecting rod 16. A second connecting rod 18 is fixedly connected to the bottom of the rotating inlet pipe 8. A bearing 19 is fixedly installed between the second connecting rod 18 and the fixing plate 17, so that the cold water distribution mechanism and the hot water distribution mechanism form a whole, ensuring a dual water distribution effect.

[0029] As attached Figure 8 , 9 As shown, the rotating mechanism includes a fixed box 20, which is fixed to the outside of the hot water inlet pipe 1. The bottom of the hot water inlet pipe 1 passes through the fixed box 20 and extends into the fixed box 20. The top of the rotating inlet pipe 8 passes through the fixed box 20 and extends into the fixed box 20. A motor 21 is fixedly installed on the top of the inner wall of the fixed box 20. A rotating shaft 22 is fixedly connected to the output end of the motor 21. A first gear 23 is fixedly connected to the bottom of the rotating shaft 22. A second gear 24 meshes with one side of the first gear 23. The second gear 24 is fixedly connected to the rotating inlet pipe 8. A rotating joint 25 is installed between the hot water inlet pipe 1 and the rotating inlet pipe 8 to facilitate driving through the fixed box 20. Thus, the rotating inlet pipe 8 is rotated through multiple structures to rotate and distribute water, forming a rotating jet that diffuses along the upper area of ​​the water storage tank. Its tilt angle is towards the tank wall, so that the water flows out and naturally approaches the tank wall.

[0030] As attached Figure 7 As shown, the cross-section of the diversion channel 7 is an isosceles trapezoid, and the inclination angle of the diversion channel 7 is set to 55°±2°, which facilitates the water discharged from the strip slit 6 through the diversion channel 7 to be divided into two streams that surge upward, thereby improving the stability of water distribution and avoiding turbulence.

[0031] As attached Figure 1 , 2, 5, 6, the included angle between the spiral guide plate 13 and the axis of the inclined guide pipe 10 is 30-60 degrees, and the helix angle of the spiral guide plate 13 matches the curvature radius of the arc-shaped guide slit 11, when the water flow flows along the spiral path of the spiral guide plate 13, the kinetic energy is dispersed into rotational kinetic energy and along the way Friction energy consumption, further reduce the axial impact speed, ensure that the hot water flows slowly along the tank wall in the form of film, avoid the direct impact of water flow or the direct vertical impact of water flow on the tank, reduce the direct impact of water flow on the cold water layer and the vertical impact of water flow on the tank, resulting in hot water and cold water mixing.

[0032] As shown in the accompanying drawings Figure 1 , 2 , 4, 8, 9, the rotating water inlet pipe 8 is rotatably connected between the fixed box 20, facilitating the rotation of the rotating water inlet pipe 8, and the top of the cold water inlet pipe 2 is sealed to prevent water flow from the top of the cold water inlet pipe 2 to cause hot water and cold water mixing.

[0033] As shown in the accompanying drawings Figure 1 , 2 , 4, 8, the number of the first shunt pipe 5 is multiple, and is distributed at equal angles along the circumference of the cold water inlet pipe 2, further ensuring the uniformity of hot water distribution.

[0034] As shown in the accompanying drawings Figure 6 , the elastic baffle 15 is made of 0.3-0.5mm thick spring steel sheet, and the surface is plasma sprayed with Al2O3 ceramic layer, so that the elastic baffle 15 can be elastically deformed to adjust the size of the water outlet of the arc-shaped guide slit 11 through water flow pressure, ensuring the stability of water distribution.

[0035] The working principle of the present application: in the city building and boiler heating system, in order to supply hot water or cold water meeting the temperature requirement to the user stably, the temperature loss control problem caused by mixing of cold and hot fluid needs to be avoided, the traditional heating system needs to use two independent tanks to store cold and hot water respectively to prevent heat mixing, while the present application can realize the upper and lower layered storage and accurate output of cold and hot water in a single water storage tank, effectively solve the problems of large space occupation and high energy consumption of traditional double tank design, through the synergistic effect of the cold water distribution mechanism and the hot water distribution mechanism, realize the physical isolation and layered distribution of cold and hot water in the water storage tank, ensure that the output hot water always keeps high temperature and the cold water always keeps low temperature, and they do not interfere with each other. In use, cold water enters the distributor through the cold water inlet pipe 2, flows down the lumen and is distributed to the first distribution pipe 5. Because the top of the cold water inlet pipe 2 is sealed, the cold water cannot flow back up, but can only be distributed to the lower area of the water storage tank through the strip-shaped gap 6 at the bottom of the first distribution pipe 5. During the distribution process, the distribution groove 7 at the top of the distribution plate 4 guides the cold water flowing out of the strip-shaped gap 6. The inclined side wall of the distribution groove 7 can evenly disperse the water flow to the lower part of the water storage tank, avoiding turbulent mixing caused by local water flow concentration, so that the water flow is divided into two streams, improving the uniformity of water distribution, and the cold water distribution area is stably concentrated in the lower layer of the water storage tank, forming a physical stratification boundary with the upper hot water. Hot water enters the rotating water inlet pipe 8 through the hot water inlet pipe 1. The first gear 23 at the output end of the rotating water inlet pipe 8 is driven to rotate by the motor 21 and the rotating shaft 22, which in turn drives the rotation of the second gear 24. The rotating water inlet pipe 8 drives the second distribution pipe 9 and the inclined flow guide pipe 10 to rotate synchronously. Hot water enters the inclined flow guide pipe 10 through the second distribution pipe 9. Because the inclined flow guide pipe 10 is designed at an angle, the water flow is guided by the spiral flow guide plate 13 to form a rotating jet at the arc-shaped flow guide gap 11, and spreads along the upper area of the water storage tank. The inclined angle of the inclined flow guide pipe 10 is directed towards the tank wall, so that the water flow naturally adheres to the tank wall after flowing out, rather than being injected towards the center of the tank. When the water flow flows along the spiral path of the spiral flow guide plate 13, the kinetic energy is dispersed into rotational kinetic energy and friction energy along the way, further reducing the axial impact speed, ensuring that the hot water flows slowly along the tank wall in a film-like manner, avoiding direct impact of the water flow, and reducing direct impact on the cold water layer. At this time, the elastic baffle 15 supported by the spring 14 is moderately opened under the pressure of the water flow. When the water flow pressure is large, the elastic baffle 15 and the spring 14 are elastically deformed, increasing the water outlet space of the arc-shaped flow guide gap 11. When the water flow pressure is small, the elastic baffle 15 and the spring 14 rebound, reducing the water outlet space of the arc-shaped flow guide gap 11, improving the applicability and avoiding the influence of water flow pressure on water distribution effect when the water flow pressure is too small. It also avoids the direct impact of water on the lower water when the water flow pressure is too small, ensuring that the cold and hot stratification interface is not damaged. The rotating movement of the rotating water inlet pipe 8 makes the hot water distribution range more uniform, ensuring that the hot water is concentrated in the upper layer of the water storage tank, and the lower layer of cold water forms a thermocline through the density difference, avoiding cold and hot mixing caused by uneven water distribution. The strip-shaped gap 6 of the cold water distribution mechanism distributes water downward, and the arc-shaped flow guide gap 11 of the hot water distribution mechanism distributes water upward and sideways. Combined with the natural density difference of cold and hot fluids in the water storage tank, a stratified thermocline is formed. The trapezoidal structure of the distribution groove 7 allows for gentle water distribution, and the spiral flow guide plate 13 and the rotating mechanism allow for rotational diffusion of hot water. Both distribution methods avoid turbulent flow and reduce disturbance to the stratification interface. The lower layer of cold water is stably output by the cold water distribution mechanism, maintaining low temperature characteristics, and the upper layer of hot water is stably output by the hot water distribution mechanism, maintaining high temperature characteristics. When cold water is discharged, cold water is continuously supplied to the lower layer of the water storage tank through the cold water inlet pipe 2, diffuses gently around through the strip-shaped gap 6 at the bottom of the first shunt pipe 5, and forms a low-temperature static layer with stable thickness under the guide of the isosceles trapezoidal slope of the shunt groove 7. This area forms a thermocline with the upper layer of hot water through the density difference. When the user opens the cold water valve, cold water is only extracted from the lower layer of the static layer. At this time, the flow stabilizing effect of the shunt groove 7 can offset the local pressure fluctuation caused by the change in water extraction volume, avoiding the sinking of the upper layer of hot water into the cold water output path due to negative pressure, and at the same time, the rigid fixing of the first connecting rod 16 and the fixed plate 17 ensures that the cold water distribution mechanism does not change position, maintaining the stability of the cold water layer boundary; When hot water is discharged, hot water enters the rotating inlet pipe 8 after entering the hot water inlet pipe 1, and then forms a diagonal water film layer on the cold water layer through the second shunt pipe 9 and the inclined flow guide pipe 10. The rotating joint 25 ensures that the hot water supply path is always unobstructed and free of cold water infiltration when the rotating inlet pipe 8 rotates 360°, continuously supplying heat to the upper layer of hot water. The hot water in the water storage tank is output through the upper part of the tank body. When the user opens the hot water valve, hot water is only extracted from the upper diagonal layer. At this time, the directional water distribution of the arc-shaped flow guide gap 11 ensures that the supplied hot water continuously covers the output port area, maintaining the stability of the local water temperature. The rotational diffusion of the spiral flow guide plate 13 makes the temperature distribution of the hot water layer uniform, avoiding fluctuations in the output water temperature caused by local cooling. The pressure response of the elastic baffle 15 can quickly adjust the size of the arc-shaped flow guide gap 11 when the output flow changes, maintaining the stability of the hot water layer pressure and preventing the cold water layer from infiltrating in the opposite direction due to pressure difference. When the user suddenly opens the hot water valve, the hot water output volume increases suddenly, which can cause the hot water layer pressure to drop temporarily. At this time, the elastic baffle 15 reduces the opening of the arc-shaped flow guide gap 11 and the elastic baffle 15 under the action of the spring 14, reduces the hot water distribution speed to maintain the layer pressure, reduces the hot water diffusion range, and prioritizes the stability of the water temperature in the output port area. The cold water first fills the lower layer area through the cold water inlet pipe 2, and the trapezoidal structure of the shunt groove 7 guides the cold water to quickly form a uniform low-temperature base. After the cold water layer thickness meets the standard, the hot water distribution mechanism is started, and the wall-hugging water distribution of the inclined flow guide pipe 10 makes the hot water slowly rise along the tank wall, avoiding the impact on the cold water layer and ensuring that the first output of hot water can reach the set temperature; In the heating of residents' homes, when the user opens the bathroom hot water faucet in the morning, the hot water in the upper layer of the water storage tank is directly delivered through the hot water output port, and the water temperature is always stable, without temperature fluctuations caused by mixing of cold and hot water. At the same time, when the kitchen cold water faucet is opened, the cold water in the lower layer of the water storage tank is delivered through the cold water output port. The gentle water distribution of the strip-shaped gap 6 ensures that the cold water layer is continuously supplied and the temperature remains unchanged, completely independent of the hot water output path. The two are physically isolated by the tank layering and water distributor structure, ensuring that the terminal water temperature is output as needed and does not interfere with each other, ensuring that the output water does not have a temperature difference, and the hot water that comes out is still hot water, and the cold water that comes out is still cold water.
