[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Reference below Figure 1-Figure 5 A cold tank 10 according to an embodiment of the first aspect of the present invention is described.

[0035] like Figure 1-Figure 5 As shown, the cold tank 10 according to the embodiment of the first aspect of the utility model comprises: a cold tank body 11 and a water outlet pipe 12. The cold tank body 11 has a water storage chamber 101, and the cold tank body 11 is provided with a water inlet 102, a water outlet 103 and an exhaust port 104; the water outlet pipe 12 is arranged in the water storage chamber 101, and the water outlet pipe 12 is connected with the water outlet 103 and the water storage chamber 101.

[0036] In this embodiment, the cold tank 10 is provided with a cold tank body 11, and the cold tank body 11 is provided with a water storage chamber 101 and a water inlet 102 and an exhaust port 104 connected to the water storage chamber 101, so that when the cold tank 10 is in use, the gas in the water storage chamber 101 can be discharged from the exhaust port 104, so that normal temperature water can smoothly flow into the water storage chamber 101 from the water inlet 102 for cooling treatment.

[0037] In this embodiment, a water outlet pipe 12 is provided, and the water outlet pipe 12 is connected with the water storage chamber 101 and the water outlet 103. The cold water formed after the normal temperature water is cooled can flow along the water outlet pipe 12 to the water outlet 103. When the user takes water, the cold water flows out from the water outlet 103 and flows into the user's water container through the water outlet structure of the water dispenser.

[0038] In this embodiment, the water outlet pipe 12 is arranged in the water storage chamber 101, so that the cold water in the water outlet pipe 12 is in the water storage chamber 101 before flowing out, which effectively avoids the influence of the external ambient temperature on the water temperature, so that the temperature of the cold water in the water outlet pipe 12 can remain unchanged. When the user takes water, the first cup of water flowing out of the cold tank 10 can always be kept at a suitable temperature, so that the user can get the cold water needed for drinking in the first cup when taking water, which greatly improves the user experience.

[0039] The water outlet pipe 12 of this embodiment is arranged in the water storage chamber 101, so that the cold tank 10 can always provide cold water to the user during the water outlet process, so that within the same time range, the cold tank 10 can provide more cold water, so that the water dispenser has a stronger cooling water capacity. At present, at an ambient temperature of 25°C, the cooling water capacity of the cold tank 10 of this embodiment can reach three liters of cold water per hour, which is much higher than the industry standard of two liters of cold water per hour.

[0040] According to the cold tank 10 of the embodiment of the utility model, a cold tank body 11 and a water outlet pipe 12 are provided, and the water outlet pipe 12 is provided in the water storage chamber 101 of the cold tank body 11, which effectively avoids the influence of the external ambient temperature on the water temperature in the water outlet pipe 12, so that the first cup of water when the cold tank 10 dispenses water can always be cold water, so that the cooling water capacity of the water dispenser is stronger, the drinking water needs of users are well met, and the user experience is improved.

[0041] In some embodiments of the present invention, Figure 3 As shown, the water outlet pipe 12 can extend vertically, the upper end of the water outlet pipe 12 is connected to the water outlet 103, and the lower end of the water outlet pipe 12 is formed with a liquid inlet, which extends to the bottom of the water storage chamber 101 and is close to the bottom wall of the water storage chamber 101.

[0042] It is understandable that water generally settles at the bottom of the cavity under the action of gravity. In the present embodiment, the cold water in the water storage chamber 101 gradually accumulates upward from the bottom of the water storage chamber 101 as the normal temperature water is injected. The temperature of the newly injected water is relatively high. Therefore, in the process of the cold tank 10 cooling the water in the water storage chamber 101, the temperature of the cold water in the water storage chamber 101 gradually decreases from top to bottom, and the temperature of the cold water at the bottom of the water storage chamber 101 is even lower.

[0043] In this embodiment, the upper end of the water outlet pipe 12 is connected to the water outlet 103, and the lower end of the water outlet pipe 12 extends to the bottom of the water storage chamber 101, so that the bottom cold water with the lowest temperature can be discharged first when the cold tank 10 discharges water, which effectively reduces the impact of the newly injected normal temperature water on the outlet water temperature and avoids the normal temperature water from flowing out directly without sufficient cooling, so that the cold tank 10 can stably discharge cold water when discharging water.

[0044] It can be understood that after the cold water in the water storage chamber 101 flows out, normal temperature water will be replenished into the water storage chamber 101, and the cold tank 10 will cool the water in the water storage chamber 101 again to reach the temperature required for the cold water to flow out. When the cold water at the bottom with the lowest temperature is stored in the water storage chamber 101 for too long, it will be cooled down multiple times, which may cause the temperature to be too low and freeze, thereby increasing the risk of freezing of the cold tank 10 and reducing the cooling efficiency of the water in the cold tank 10. In this embodiment, the lower end of the water outlet pipe 12 is extended to the bottom of the water outlet chamber and close to the bottom wall of the water storage chamber 101, so that the cold water on the bottom wall with the lowest temperature can be discharged in time, so that the operation of the cold tank 10 is more stable and reliable during long-term use.

[0045] In this embodiment, the water outlet pipe 12 extends vertically, has a simple structure and is easy to arrange. The liquid inlet of the water outlet pipe 12 is close to the bottom wall of the water storage chamber 101, which can facilitate the bottom cold water with the lowest temperature to flow out from the liquid inlet, and well meet the water outlet needs of the cold tank 10.

[0046] In one embodiment of the present invention, the distance between the liquid inlet and the bottom wall of the water storage chamber 101 may range from greater than or equal to 2.5 mm to less than or equal to 7.5 mm.

[0047] In this embodiment, the distance between the liquid inlet and the bottom wall of the water storage chamber 101 is set to be less than or equal to 7.5 mm, so that the liquid inlet can be closer to the bottom wall of the water storage chamber 101 so that the cold water at the bottom with the lowest temperature can be discharged in time. The distance is set to be greater than or equal to 2.5 mm, so that there is enough flow space between the liquid inlet and the bottom wall, so that the cold water can be discharged stably and smoothly. Figure 3 As shown in the figure, L represents the distance between the liquid inlet and the bottom wall of the water storage chamber 101, and the distance L can be 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 6mm, 7mm, 7.5mm and so on.

[0048] In one embodiment of the present invention, Figure 3 As shown, the liquid inlet can be arranged inclined relative to the horizontal plane.

[0049] In this embodiment, the liquid inlet is inclined relative to the horizontal plane, which can further increase the space between the liquid inlet and the bottom wall of the water storage chamber 101, thereby increasing the area of ​​the liquid inlet, so that cold water can flow from the liquid inlet into the water outlet pipe 12 more smoothly, and the lower end of the liquid inlet can be closer to the bottom wall of the water storage chamber 101, so that the dimensional accuracy requirement of the water outlet pipe 12 and the bottom wall of the water storage chamber 101 is reduced during assembly, making it more convenient to assemble the water outlet pipe 12 and the cold tank body 11.

[0050] In some examples of the present invention, the angle between the liquid inlet and the horizontal plane may be greater than or equal to 40° and less than or equal to 50°.

[0051] In this way, there can be enough flow space between the liquid inlet and the bottom wall of the water storage chamber 101, so that cold water can flow stably and smoothly from the water storage chamber 101 into the water outlet pipe 12, and the liquid inlet extends within a certain range in the axial direction of the water outlet pipe 12, so that the liquid inlet can be kept close to the bottom wall of the water storage chamber 101, so that the water flowing into the water outlet pipe 12 is all the bottom cold water with a lower temperature, so that the outlet water temperature of the cold tank 10 is relatively stable. For example, refer to Figure 3 As shown in the figure, α is represented by the angle between the liquid inlet and the horizontal plane, and the angle α can be 40°, 41°, 43°, 45°, 48°, 49°, 50°, etc.

[0052] In some embodiments of the present invention, Figure 3 As shown, the water inlet 102 , the water outlet 103 and the air outlet 104 may be disposed on the upper side of the cold tank body 11 .

[0053] In this embodiment, the water inlet 102, the water outlet 103 and the exhaust port 104 are all arranged on the upper side of the cold tank body 11, which has a simple structure and a compact layout. It can conveniently meet the needs of water inlet, water outlet and exhaust of the water storage chamber 101, and can facilitate the assembly and arrangement of the cold tank body 11 and the water inlet and outlet structure and the exhaust structure of the water dispenser. The water inlet 102, the water outlet 103 and the exhaust port 104 are arranged on the same side of the cold tank body 11, so that when the cold tank 10 is assembled, the structural components connected and arranged with the water inlet 102, the water outlet 103 and the exhaust port 104 can all be assembled and arranged on the same side of the cold tank body 11, which makes it easier to perform automated mechanical assembly operations during the assembly and processing of the water dispenser, thereby greatly reducing the physical burden of human labor and improving the production efficiency of the water dispenser.

[0054] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the cold tank body 11 may include: a tank body 111 and a cover body 112, the tank body 111 is formed with a water storage chamber 101, and the upper side of the water storage chamber 101 is open; the cover body 112 is covered on the open side of the water storage chamber 101, and the cover body 112 is provided with a water inlet 102, a water outlet 103 and an exhaust port 104.

[0055] In this embodiment, the cold tank body 11 is provided with a tank body 111 and a cover body 112. The cover body 112 is covered on the open side of the water storage chamber 101 of the tank body 111. The structure is simple and the assembly is convenient. The cover body 112 and the tank body 111 can cooperate to form a closed water storage chamber 101. This can improve the insulation effect of the cold tank body 11 on the cold water in the water storage chamber 101 to a certain extent, so that the temperature of the cold water in the water storage chamber 101 can be better maintained stable after cooling, so that the cold water temperature of the cold tank 10 can be better maintained at a lower temperature state, and the cooling water capacity of the cold tank 10 can be better to a certain extent.

[0056] In this embodiment, the water inlet 102, the water outlet 103 and the exhaust port 104 are all arranged on the cover body 112, which has a simple structure, good integration and is easy to process and manufacture.

[0057] In one embodiment of the present invention, Figure 3 and Figure 5 As shown, the cover body 112 may be provided with a water inlet head 1121 , which is disposed on a side of the water inlet 102 facing the water storage chamber 101 , and the water inlet head 1121 is provided with a grille hole communicating with the water inlet 102 and the water storage chamber 101 .

[0058] In this embodiment, a water inlet head 1121 is arranged at the water inlet 102, and the water inlet head 1121 is provided with a grille hole, so that when the cold tank 10 is filled with water, the normal temperature water is broken up into a shower-like water under the action of the water inlet head 1121, and the water enters the water storage chamber 101 through the grille hole, so that the impact force of the incoming water on the cold water in the water storage chamber 101 is greatly reduced, thereby slowing down the time for the higher temperature normal temperature water and the relatively cold water to mix, and then the time for the cold water temperature to rise is increased, so that the frequency of starting the refrigeration of the cooling equipment used to cool the water is reduced, thereby reducing the energy consumption during the operation of the water dispenser, so that the water outlet temperature of the cold tank 10 during the normal temperature water inlet process can still have a lower water temperature.

[0059] In this embodiment, a water inlet head 1121 with grille holes is provided to disperse the incoming water and mix it with the cold water, so that the incoming water and the cold water can be mixed more evenly and fully, so that the water temperature in the water storage chamber 101 is more uniform and stable. To a certain extent, the cooling efficiency of the cold tank 10 can be higher and the water outlet temperature can be more stable during cooling, so that the cold tank 10 can provide cold water that meets the needs more quickly.

[0060] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the cold tank 10 may further include: a fastening collar 13 , which is sleeved on the radially outer side of the cover body 112 to fix the cover body 112 to the tank body 111 , and a sealing ring 14 , which is arranged between the fastening collar 13 and the cover body 112 .

[0061] In this embodiment, a fastening collar 13 is provided to fix the cover body 112 and the tank body 111 together, which has a simple structure, is convenient to fix, and has a reliable connection. A sealing ring 14 is provided to seal the fastening collar 13 and the cover body 112, so that the water storage cavity 101 formed after the cover body 112 and the tank body 111 are assembled has better sealing properties, thereby allowing the cold tank body 11 to operate more stably.

[0062] In some examples of the present invention, Figure 3 As shown, the cover body 112 may be provided with a fixing groove, which is arranged on the outer peripheral side of the cover body 112 and extends in a ring shape along the circumference of the cover body 112 . The sealing ring 14 is fixed in the sealing groove and abuts against the end edge and inner wall surface of the tank body 111 .

[0063] In this embodiment, a fixing groove is provided on the cover body 112 , which has a simple structure and is convenient for installing and fixing the sealing ring 14 and the cover body 112 .

[0064] In some examples of the present invention, Figure 3As shown, the cover 112 may be provided with a plug-in slot, which extends vertically and one end of which is connected to the water outlet 103, and the upper end of the water outlet pipe 12 is plugged and fixed in the plug-in slot. This can facilitate the connection and fixation of the water outlet pipe 12 and the cover 112, making it easier to assemble the water outlet pipe 12 in the cold tank 10.

[0065] In some embodiments of the present invention, Figure 3 As shown, the cold tank 10 may further include a drain pipe 15, which is disposed at the bottom of the tank body 111 and communicates with the water storage chamber 101. This makes it easy to drain the cold water in the water storage chamber 101 for cleaning and descaling, so that the cold tank 10 can operate stably and well during long-term use.
