[0020] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0021] like Figures 1 to 3 As shown in the figure, this utility model embodiment provides a cold water tank, which includes a tank body 1, an isolation cover 2, a cooling component 3, and a water pump 4.

[0022] The tank 1 has a circulating water inlet 11, a circulating water outlet 12, a tank inlet 13, and a tank outlet 14.

[0023] An isolation cover 2 is installed inside the housing 1, dividing the interior of the housing 1 into an inner cavity 15 and an outer cavity 16 surrounding the inner cavity 15. The circulating water inlet 11, the circulating water outlet 12, and the housing outlet 14 are all connected to the inner cavity 15. Water within the inner cavity 15 can be discharged through the housing outlet 14.

[0024] The cooling component 3 is located inside the inner cavity 15. The cooling component 3 is used to exchange heat with the water in the inner cavity 15, thereby cooling the water in the inner cavity 15.

[0025] The cooling component 3 is spiral-shaped. The circulating water outlet 12 on the housing 1 is opposite to the axis of the cooling component 3, and the circulating water inlet 11 and the area between the cooling component 3 and the isolation cover 2 are opposite.

[0026] Water pump 4 is connected to housing 1. The inlet 41 of water pump 4 is connected to the circulating water inlet 11, and the outlet 42 of water pump 4 is connected to the circulating water outlet 12. Water pumped by water pump 4 flows upwards from the bottom of the cooling element 3, and flows into the area between the cooling element 3 and the isolation cover 2 under the obstruction of the isolation cover 2. Then, it is drawn in and pumped out by water pump 4, realizing the flow of water between the inner and outer sides of the cooling element 3 for heat exchange. (See...) Figure 2 The direction of the middle arrow indicates the direction of the water's circulating flow.

[0027] The inner side of the cooling component 3 can be understood as the area enclosed by the cooling component 3, and the outer side of the cooling component 3 can be understood as the area outside the area enclosed by the cooling component 3.

[0028] In this embodiment, the cold water tank cools the water in the inner cavity 15 through the cooling component 3, and the water pump 4 circulates the water inside and outside the cooling component 3 to form strong convection heat exchange and rapid cooling. At the same time, the outer cavity 16 is arranged around the inner cavity 15 to isolate the inner cavity 15 from the outside world, thereby preventing the loss of cold energy in the inner cavity 15 and greatly improving the cooling efficiency.

[0029] like Figure 3 and Figure 5 As shown, in some embodiments, the water inlet 13 of the tank can be connected to the outer cavity 16, and the isolation cover 2 is provided with an exchange port 22 that connects the outer cavity 16 and the inner cavity 15.

[0030] As the cooled water in the inner cavity 15 is discharged through the outlet 14, water can be replenished into the outer cavity 16 through the inlet 13. The cooled water entering the outer cavity 16 then flows back into the inner cavity 15 through the exchange port 22 to participate in cooling. This allows for simultaneous drainage and replenishment of water. Figure 3 The direction of the middle arrow indicates the direction of water flow.

[0031] In this embodiment, a high water level probe 5 and a low water level probe 6 can be fixed inside the inner cavity 15. The high water level probe 5 is located above the low water level probe 6. The high water level probe 5 and the low water level probe 6 are used to detect the height of the water level in the inner cavity 15, respectively.

[0032] The water inlet 13 on the housing 1 can be connected to a water supply system. The water supply system can be connected to the high water level probe 5 and the low water level probe 6 respectively. When the cold water in the inner cavity 15 overflows the high water level probe 5, a full water signal will be generated, and the water supply system will stop supplying water to the housing 1. When the cold water in the inner cavity 15 no longer overflows the low water level probe 6, a water shortage signal will be generated, and the water supply system will start injecting water into the housing 1.

[0033] like Figure 5 As shown, in some embodiments, the number of exchange ports 22 on the isolation cover 2 can be multiple, and the multiple exchange ports 22 are arranged around the bottom periphery of the isolation cover 2. In this way, the cold water entering the outer cavity 16 flows directly into the inner cavity 15 through the exchange ports 22 at the bottom of the isolation cover 2, is drawn in by the water pump 4, and then pumped into the inner side of the cooling component 3 to participate in rapid flow.

[0034] The shape of the exchange port 22 is not specifically limited in this application; it can be square or round, etc.

[0035] In some embodiments, the water inlet of the tank 1 is located at the top of the tank 1, and the circulating water inlet 11 and the circulating water outlet 12 are both located at the bottom of the tank 1.

[0036] like Figure 4 As shown, in some embodiments, the cooling element 3 can be a spiral tube. The cooling tube of the cooling element 3 has a tube inlet and a tube outlet, and a cooling medium can flow through the cooling tube. The cooling medium inside the tube can exchange cooling with the water in the inner cavity 15, thereby reducing the temperature of the water in the inner cavity 15. At the same time, constructing the cooling element 3 as a spiral tube can increase the contact area, thereby improving the cooling efficiency.

[0037] like Figure 5 As shown, in some embodiments, the shape of the isolation cover 2 can be a cylindrical body with an open bottom. The isolation cover 2 covers the entire cooling component 3. The inner side of the isolation cover 2 is the inner cavity 15. The area between the isolation cover 2 and the inner wall of the box 1 forms the outer cavity 16. The bottom of the isolation cover 2 abuts against the lower cover of the box 1, thereby separating the inner cavity 15 and the outer cavity 16.

[0038] The top of the isolation cover 2 is directly opposite the top of the cooling component 3. When the water pump 4 pumps out cold water, it flows from bottom to top and is blocked by the top of the isolation cover 2 before spreading outwards. Then, it is blocked by the wall of the isolation cover 2 and flows downwards to exchange heat with the cooling component 3 for the second time, thereby accelerating the cooling.

[0039] The top of the isolation cover 2 may be provided with a fixing part 21, which can be connected to the top cover of the box 1 to fix the isolation cover 2. The connection method between the fixing part 21 and the top cover of the box 1 is not specifically limited, for example, it can be connected by a screw.

[0040] Of course, the isolation cover 2 can also be connected to the lower cover of the housing 1 to fix the entire isolation cover 2.

[0041] The isolation cover 2 can be cylindrical or rectangular, etc. The inner diameter of the isolation cover 2 must be much larger than the radial distance between it and the inner peripheral wall of the box 1.

[0042] like Figure 1 As shown, in some embodiments, the axis of the isolation cover 2 can be coaxial with the axis of the cooling element 3, thereby ensuring that the water flow inside the cooling element 3 can be evenly distributed around the cooling element 3 after being dispersed by the top of the isolation cover 2.

[0043] This utility model embodiment also provides a water dispenser, which may include a cold water tank as described in any of the above embodiments, thereby improving the efficiency of cold water preparation in the water dispenser.

[0044] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
