Generally, a water inlet pipe 3 is connected to the water inlet 13 of the cold tank 1 to pass water at room temperature. Optionally, the water inlet 13 of the cold tank 1 is provided with an outer joint 111, and the water inlet pipe 3 is sleeved on the outer joint 111. In this way, the communication between the water inlet pipe 3 and the water inlet 13 can be easily realized.

The technical solution of the present application is provided with the guide tube 2 and the speed plate 10, and the normal temperature water entering the cold tank 1 can be sprayed out as a water film around the cooling tank 1 through the spraying slit, and the sprayed water film will be The speed plate 10 reduces speed by friction, and after decelerating to zero speed, it freely falls to the cold water end of the cold tank 1, thereby eliminating the impact of the initial water inlet speed on the cold water in the cold tank 1 and avoiding the room temperature water and the cold water in the cold tank 1 from mixing too fast , And then can take out a large amount of cold water as much as possible.

In this application, in order to make the water flowing out of the water outlet end of the draft tube 2 spray out from the spray slit, and form a deceleration water film that is attached to the speed plate 10, the flow rate of the water inlet and the water outlet end of the draft tube 2 are When the diameter (circumference) is fixed, the width of the injection slit should not be too large. In an optional embodiment, when the water inlet flow rate of the cold tank 1 is 1.85 L/min, and the circumference of the water outlet end of the draft tube 2 is 25.4 mm, the width of the spray slit is 1.5 mm. At this time, The influent water can be sprayed from the spraying slit and form a deceleration water film that is attached to the deceleration plate 10.

In this embodiment, the cold tank 1 usually includes a tank body 12 and a tank cover 11 arranged on the upper end of the tank body 12. Further, the deceleration plate 10 is a cover plate of the tank cover 11, so the structure of the cold tank 1 is simpler. However, the design is not limited to this. In other embodiments, the deceleration plate 10 may be an additional component and located below the cover plate of the tank cover 11, and it may be fixed to the tank cover 11 or the tank body 12.

Further, the water outlet end of the draft tube 2 is adjacent to the center position of the cover plate of the tank cover 11, so that the water film sprayed from the spray slit can be provided in all directions of the water outlet end of the draft tube 2 Longer deceleration stroke, so that the water film in all directions can be fully decelerated, and then fall freely to the cold water end of the cold tank 1.

Further, the water inlet 13 is provided on the cover plate of the tank cover 11. However, the design is not limited to this. In other embodiments, the water inlet 13 may also be provided at the upper end of the tank 12. Of course, in this embodiment, arranging the water inlet 13 on the cover plate of the tank cover 11 can enable the cold tank 1 to obtain a higher water level; in addition, the structure of the tank body 12 can also be simplified. Optionally, the cover plate of the tank cover 11 is provided with an inner joint 112 at the water inlet 13, and the water inlet end of the diversion tube 2 is sleeved on the inner joint 112. In this way, it is convenient to realize the water intake of the diversion tube 2 The connection between the end and the water inlet 13.

Further, the flow guide tube 2 is configured as a U-shaped tube, so that the flow guide tube 2 has a simple structure and can well divert the inlet water to the lower side of the speed plate 10; however, the design is not limited to this, and other In the embodiment, the guide tube 2 can also be arranged in other shapes, such as but not limited to a spiral shape, as long as it can divert the inlet water to the lower side of the speed plate 10.

Further, the lower side surface of the speed brake 10 is configured as a rough surface full of protrusions and/or pits. In this way, the deceleration effect of the lower side of the speed brake 10 on the water film can be enhanced, so as to prevent the water film from impacting the speed brake 10 At the edge, there is still a higher impact velocity. Optionally, when the speed plate 10 is a metal plate (usually a stainless steel plate), the lower side of the metal plate can be treated by pickling, so that the lower side becomes a rough surface. In addition, optionally, when the speed brake 10 is a plastic plate, the speed brake 10 with the rough surface on the lower side can be directly injected through an injection mold full of protrusions and/or pits. However, the design is not limited to this. In other embodiments, a material with viscous damping properties, such as but not limited to food-grade silicone film, can be attached to the lower side of the speed plate 10 to improve the lower side of the speed plate 10 The friction of the water film enhances its deceleration effect.

In this application, when the speed of the water film sprayed by the spray slit and the diameter of the speed plate 10 are fixed, the lower side of the speed plate 10 with a suitable deceleration effect can be selected to make the final water film radius larger than or It is equal to half of the radius of the speed plate 10, and the distance between the final water film edge and the edge of the speed plate 10 is 10mm~15mm, so that the influent water can get a longer deceleration stroke after spraying to fully consume it. Kinetic energy, and at the same time, prevent the influent water from directly impacting the side wall of the cold tank 1 (usually the edge of the tank cover 11) after spraying.

Further, a water diversion structure 101 is provided at a position of the deceleration plate 10 directly opposite to the water outlet end of the guide tube 2, and the water diversion structure 101 is formed with a plurality of water diversion grooves distributed along the circumferential direction. It can be understood that the plurality of water diversion grooves respectively face different directions, so that the water sprayed from the spray slits is dispersed and directed to different directions through the plurality of water diversion grooves, so that the water film in each direction is more uniform.

It should be noted that, in this embodiment, only the water diversion structure 101 is provided on the deceleration plate 10. However, the present design is not limited to this. In some other embodiments, the water diversion structure 101 may be provided only in the water outlet end of the diversion tube 2. In still other embodiments, the water diversion structure 101 can be provided on the speed plate 10 and the water diversion structure 101 can be provided in the water outlet end of the guide tube 2.

In this embodiment, further, the water diversion structure 101 includes a plurality of water diversion ribs 102 protruding from the lower side of the speed plate 10, and the plurality of water diversion ribs 102 intersect on the same axis so as to lie between any two adjacent ones. A water diversion groove is restricted between the water diversion ribs 102; in this way, the water diversion groove formed has a deeper water diversion stroke, thereby having a better water diversion effect. However, the present design is not limited to this. In other embodiments, water diversion grooves facing different directions can also be directly excavated on the lower side of the speed plate 10. In this embodiment, generally, four water diversion ribs 102 are provided to form water diversion grooves facing in four different directions, so as to disperse and guide the water sprayed from the spraying slits to four different directions; Of course, in other embodiments, three water diversion ribs 102 can also be provided to form water diversion grooves facing three different directions. In this embodiment, optionally, the plurality of water-distributing ribs 102 and the speed plate 10 are integrally formed to improve the production efficiency of the product.

Further, the water diversion structure 101 partially extends into the water outlet end of the diversion tube 2, so that the function of dispersing and diversion of the outlet water can be better realized.
