The invention provides a cold tank.

Referring to fig. 1 and 2, in an embodiment of the present invention, the cold tank 1 is used for a water dispenser, and is provided with a water inlet 13, and the cold tank 1 is further provided with:

the speed reducing plate 10 is arranged at the upper end of the cooling tank 1; and

the flow guide pipe 2 is provided with a water inlet end and a water outlet end; wherein, honeycomb duct 2 intake end with water inlet 13 intercommunication, honeycomb duct 2's play water end neighbour locates the downside of air brake 10, and separates out the injection slit with the downside of air brake 10.

Without loss of generality, the water inlet 13 of the cold tank 1 is externally connected with a water inlet pipe 3 for introducing normal temperature water. Optionally, the water inlet 13 department of cold jar 1 is equipped with outer joint 111, and inlet tube 3 cup joints in this outer joint 111, so, can be convenient for realize inlet tube 3 with intercommunication between the water inlet 13.

According to the technical scheme, through the arrangement of the flow guide pipe 2 and the speed reducing plate 10, the normal-temperature water entering the cold tank 1 can be sprayed out to the periphery in a water film mode through the spraying slit, the sprayed water film can rub with the speed reducing plate 10 to reduce the speed, and the water film is reduced to zero speed and then freely falls to the upper end of cold water of the cold tank 1, so that the impact of the initial water inlet speed on the cold water in the cold tank 1 is eliminated, the normal-temperature water is prevented from being mixed with the cold water in the cold tank 1 too fast, and further the low-temperature cold water can be taken out as much as possible.

In the present invention, in order to make the water flowing out of the water outlet end of the flow guide tube 2 be jetted from the jet slit and form a decelerating water film attached to the decelerating plate 10, the width of the jet slit should not be too large under the condition that the water inflow rate and the pipe diameter (circumference) of the water outlet end of the flow guide tube 2 are both fixed. In an alternative embodiment, when the water inlet flow rate of the cooling tank 1 is 1.85L/min and the perimeter of the water outlet end of the draft tube 2 is 25.4mm, the width of the injection slit is 1.5mm, and at this time, the inlet water can be sprayed out from the injection slit and forms a deceleration water film attached to the deceleration plate 10.

Without loss of generality, in the present embodiment, the cold tank 1 includes a tank body 12 and a tank cover 11 covering the upper end of the tank body 12. Further, the speed reduction plate 10 is a cover plate of the can lid 11, so that the structure of the cold can 1 is simpler. However, the design is not limited thereto, and in other embodiments, the speed reduction plate 10 may be an additional component, and is located below the cover plate of the tank cover 11, and may be fixed to the tank cover 11 or the tank body 12.

Furthermore, the water outlet end of the flow guide pipe 2 is adjacent to the center of the cover plate of the tank cover 11, so that the water film sprayed from the spray slit can have a longer deceleration stroke in each direction of the water outlet end of the flow guide pipe 2, and the water film part in each direction can freely fall to the upper end of the cold water of the cold tank 1 after being fully decelerated.

Further, the water inlet 13 is provided in the cover plate of the tank cover 11. However, the design is not limited thereto, and in other embodiments, the water inlet 13 may be disposed at the upper end of the tank 12. Of course, in this embodiment, the water inlet 13 is disposed on the cover plate of the tank cover 11, so that the cold tank 1 can obtain a higher water level; in addition, the structure of the can body 12 can 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 flow guide pipe 2 is sleeved on the inner joint 112, so that the communication between the water inlet end of the flow guide pipe 2 and the water inlet 13 can be conveniently realized.

Furthermore, the guide pipe 2 is a U-shaped pipe, so that the guide pipe 2 is simple in structure and can well guide the inflow water to the lower side surface of the speed reducing plate 10; however, the design is not limited thereto, and in other embodiments, the draft tube 2 may be configured in other shapes, such as but not limited to a spiral shape, as long as the inlet water can be guided to the lower side surface of the speed reduction plate 10.

Further, the lower side surface of the speed reduction plate 10 is provided with a rough surface which is fully distributed with protrusions and/or pits, so that the speed reduction effect of the lower side surface of the speed reduction plate 10 on the water film can be enhanced, and the water film is prevented from still having higher impact speed when impacting the edge of the speed reduction plate 10. Alternatively, when the speed reduction plate 10 is a metal plate (typically, a stainless steel plate), the lower side surface of the metal plate may be treated by pickling to become a rough surface. In addition, alternatively, when the speed reduction plate 10 is a plastic plate, the speed reduction plate 10 with the rough surface on the lower side can be directly injection-molded through an injection mold which is fully distributed with protrusions and/or pits. However, the design is not limited thereto, and in other embodiments, a material with viscous damping property, such as but not limited to a food-grade silicon membrane, may be attached to the lower side of the speed reduction plate 10 to increase the friction force of the lower side of the speed reduction plate 10 facing the water membrane, thereby enhancing the speed reduction effect.

In the present invention, when the speed of the water film ejected from the ejection slit and the diameter of the speed reduction plate 10 are determined, the lower side surface of the speed reduction plate 10 with a suitable speed reduction effect can be selected so that the radius of the final water film is greater than or equal to half of the radius of the speed reduction plate 10 and the distance between the edge of the final water film and the edge of the speed reduction plate 10 is 10mm to 15mm, so that the water intake can obtain a long speed reduction stroke after being ejected, thereby sufficiently consuming the kinetic energy thereof and avoiding the water intake from directly impacting the side wall (usually the cover edge of the can cover 11) of the cold-storage can 1 after being ejected.

Furthermore, a water diversion structure 101 is arranged at the position of the speed reducing plate 10 opposite to the water outlet end of the draft tube 2, and a plurality of water diversion grooves distributed along the circumferential direction are formed in the water diversion structure 101. It can be understood that the plurality of water diversion grooves are respectively oriented to different directions so as to guide the water dispersed from the spray slit to different directions through the plurality of water diversion grooves, thereby making the water film in each direction more uniform.

In this embodiment, the water diversion structure 101 is provided only on the speed reduction plate 10. However, the design is not limited thereto, and in other embodiments, the water diversion structure 101 may be disposed only in the water outlet end of the flow guide tube 2. In other embodiments, the water diversion structure 101 may be disposed on the speed-reducing plate 10, and the water diversion structure 101 may be disposed at the water outlet end of the flow guiding pipe 2.

In this embodiment, further, the water diversion structure 101 includes a plurality of water diversion ribs 102 protruding from the lower side surface of the speed reduction plate 10, and the plurality of water diversion ribs 102 intersect with each other on the same axis to define a water diversion trench between any two adjacent water diversion ribs 102; therefore, the formed water diversion groove has a deeper water diversion stroke, thereby having a better water diversion effect. However, the design is not limited thereto, and in other embodiments, the diversion grooves facing different directions may be directly dug on the lower side surface of the speed reduction plate 10. In this embodiment, generally, four diversion ribs 102 are provided to form diversion grooves facing four different directions, so as to guide the water dispersed from the spray slit to four different directions; of course, in other embodiments, three diversion ribs 102 may be provided to form diversion trenches facing three different directions. In this embodiment, optionally, the plurality of water diversion ribs 102 and the speed reduction plate 10 are integrally formed, so as to improve the production efficiency of the product.

Furthermore, the water diversion structure 101 partially extends into the water outlet end of the flow guide pipe 2, so that the function of dispersing and guiding the discharged water can be better realized.
