[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1:

[0027] See Figures 1 to 3 As shown, the temperature equalization structure of the cold storage and melting water cooler includes a body 1, a control system 2 and a refrigeration system 3 on the body 1, a cold storage water tank 5 inside the body 1, and a cold water chamber 501 formed inside the cold storage water tank 5 for storing cold liquid. The refrigeration system 3 is connected to the cold storage water tank 5, and a fluid disturbance device is provided on the body 1 or the cold storage water tank 5. The fluid disturbance device is connected to a disturbance structure that causes the cold liquid to flow.

[0028] The fluid disturbance device is a stirring motor 10, which is installed on either side of the cold water storage tank 5, and its output shaft extends into the cold water chamber 501 and is connected to a stirring paddle 1001. The stirring paddle 1001 constitutes a disturbance structure.

[0029] When the stirring motor 10 is working, this temperature equalization structure drives the stirring paddle 1001 to rotate in the cold storage liquid, so that the cold storage liquid in the cold storage tank is in motion, maintaining the water temperature uniformity in all parts of the cold storage tank, improving the cooling efficiency of drinking water, and preventing freezing.

[0030] It also includes a first temperature sensor 13 and a second temperature sensor 14 that are electrically connected to the control system 2. The first temperature sensor 13 and the second temperature sensor 14 are disposed inside the cold water storage tank 5 and are positioned far apart from each other.

[0031] At least two temperature sensors are installed in the cold water storage tank 5, namely the first temperature sensor 13 and the second temperature sensor 14. The first temperature sensor 13 and the second temperature sensor 14 can be arranged at different heights, left and right, or opposite sides. When the temperature difference between the two temperature sensors exceeds the set range, the control system 2 drives the stirring motor 10 in this embodiment or the circulating water pump 9 in embodiment 2 to work until the temperature difference reaches the preset range, thereby achieving water temperature balance.

[0032] The opening of the cold water storage tank 5 is connected to a mounting support plate 53. The stirring motor 10 is fixedly connected to the mounting support plate 53, and the stirring paddle 1001 on the output shaft is positioned in the middle of the cold water chamber 501. The mounting support plate 53 allows the stirring paddle 1001 to be positioned in the middle of the cold water chamber 501, so that the cold liquid in the entire cold water chamber 501 can be evenly disturbed. In this embodiment, the first temperature sensor 13 and the second temperature sensor 14 are simultaneously mounted on the mounting support plate 53 for easy installation and removal.

[0033] The cold water storage tank 5 is equipped with a repeatedly wound evaporator coil 6 and a cold water coil 7. The evaporator coil 6 and the cold water coil 7 exchange heat in the cold water chamber 501. The evaporator coil 6 is connected in series to the refrigeration system 3. The body 1 is equipped with a water outlet 4 connected to one end of the cold water coil 7. The other end of the cold water coil 7 is connected to the water source W. The cooperation between the evaporator coil 6 and the cold water coil 7 enables the body 1 to output cold water.

[0034] Moreover, in this embodiment, see Figure 2 As shown, the evaporator coil 6 and the cold water coil 7 are both spiraled along the horizontal plane to form one or more planar spiral structures arranged vertically. The evaporator coil 6 is located in the upper part of the cold water cavity 501, and the cold water coil 7 is located in the lower part of the cold water cavity 501.

[0035] For more embodiments, see Figure 5 and Figure 6 As shown, the cold water coil 7 is replaced by a water-carbonate mixing tank 15. The water-carbonate mixing tank 15 is used to mix purified water and carbon dioxide. Through the cooperation of the evaporator coil 6 and the water-carbonate mixing tank 15, the machine body 1 can produce cold bubble water. In this embodiment, the evaporator coil 6 is spirally wound along the height direction to form one or more sleeve-shaped cage structures arranged inside and outside, and the evaporator coil 6 is sleeved on the outer periphery of the water-carbonate mixing tank 15. In addition, an atomizing nozzle 16 is connected to the water inlet of the water-carbonate mixing tank 15 and placed inside the water-carbonate mixing tank. The purified water is sprayed into the water-carbonate mixing tank 15 in the form of water mist through the atomizing nozzle 16, which can better mix with carbon dioxide.

[0036] This structure utilizes the evaporator coil 6 to lower the water temperature in the cold water storage tank 5. By immersing the entire cold water coil 7 in cold water, the cooling efficiency of drinking water can be improved, thereby increasing the amount of cold water produced per unit time and improving the uniformity of cooling.

[0037] The machine body 1 is also equipped with a water supply valve 8 that is electrically connected to the control system 2. The water inlet of the water supply valve 8 is connected to the water source W, and the water outlet of the water supply valve 8 is connected to a water supply pipe 81 that extends into the cold water chamber 501.

[0038] When the water level detector detects that the water level in the cold water tank 5 is too low, it then activates the water supply valve 8, which opens the water source and replenishes the cold water chamber 501 with water, ensuring that the evaporator coil 6 and the cold water coil 7 are completely immersed in water.

[0039] The cold water storage tank 5 includes a box-shaped inner liner 51, which defines a cold water chamber 501. Insulation cotton 52 is connected to the outer side walls and bottom wall of the inner liner 51. The cold water storage tank 5 with this structure can improve the heat preservation capacity and reduce the absorption of external heat by the water in the cold water storage tank 5.

[0040] The machine body 1 is also equipped with a sterilizer 11 and a water intake solenoid valve 12 electrically connected to the control system 2. The water intake solenoid valve 12 and the sterilizer 11 are connected in series between the outlet end of the cold water coil 7 and the water nozzle 4. When the user needs to dispense cooled drinking water, the user activates the water intake solenoid valve 12, and the cooled drinking water flows out from the water nozzle 4. During the flow, the water passes through the sterilizer 11 to disinfect and sterilize the cooled drinking water, ensuring the safety of the cooled drinking water and improving its hygiene.

[0041] In addition, the outlet end of the carbonated water mixing tank 15 is connected to the water nozzle 4 by a throttling pipe 17. The flow rate of the carbonated water is adjusted by the length of the throttling pipe 17, so that the flow rate of the water is proportional to the flow rate of the booster pump entering the carbonated water mixing tank 17, thereby ensuring continuous water output without producing air jets and improving the aeration effect of the carbonated water.

[0042] The body 1 includes a sheet metal outer shell 101, and a partition plate 102 is provided inside the sheet metal outer shell 101. The partition plate 102 divides the inner cavity of the sheet metal outer shell 101 into an upper chamber 103 and a lower chamber 104. The control system 2 and the refrigeration system 3 are located in the lower chamber 104, and the cold water storage tank 5 is located in the upper chamber 103. The water storage tank 5 and the electric refrigeration system 3 are arranged separately to ensure electrical safety and prevent electric leakage in the event of a water leakage accident in the cold water storage tank 5.

[0043] The refrigeration system 3 also includes a compressor 31, a condenser 32 and a throttling device. A cooling fan 33 is provided on one side of the condenser 32. One end of the evaporator coil 66 is connected to the compressor 31 and the other end is connected to the condenser 32. The structure of the refrigeration system 3 is a conventional technology, and its structure and principle will not be described in detail here.

[0044] The front side of the sheet metal housing 101 is connected to a control box 24. The disinfection and sterilization device 11 and the water intake solenoid valve 12 are housed in the control box 24. The water intake nozzle 4 is fixed to the bottom surface of the control box 24.

[0045] Among them, see Figure 7 and Figure 8 As shown, the control box 24 includes a box body 25 fixedly connected to the sheet metal shell 101. The box body 25 is provided with a semi-open opening 241. An L-shaped box cover 26 that can open or close the opening 241 is connected to the box body 25. The control box 24 that can be opened facilitates the inspection and maintenance of structures such as the disinfection and sterilization device 11 and the water intake solenoid valve 12.

[0046] The bottom of the box body 25 is provided with a hinge seat 251, and the hinge seat 251 is provided with a hinge shaft groove 252 extending along the front and rear direction of the machine body. The hinge shaft groove 252 includes an open position at the front end and a closed position at the rear end. The bottom of the front wall 26a of the L-shaped box cover 26 is fixedly provided with an L-shaped connecting plate 261, and the L-shaped connecting plate 261 is provided with a hinge shaft 262 that slides with the hinge shaft groove 252. The rear of the top wall 26b of the L-shaped box cover 26 is fixedly provided with a latch 263, and a latch is formed between the latch 263 and the top wall 26b.

[0047] In addition, a connection hole 253 is provided on the left side wall and / or right side wall of the box body 25, and a locking plate 264 is connected to the L-shaped box cover 26. The locking plate 264 has a threaded hole 265 corresponding to the connection hole 253. By passing a bolt through the connection hole 253 and the threaded hole 265, the L-shaped box cover 26 is fastened to the box body 25 to close the opening 241.

[0048] The control box 24 with the above structure has the following method for opening or closing its L-shaped cover 26:

[0049] When opening, first loosen the bolts to release the locking connection between the L-shaped box cover 26 and the box body 25, then pull the L-shaped box cover 26 forward to slide the hinge pin 262 from the closed position of the hinge pin groove 252 to the open position, and finally flip the L-shaped box cover 26 forward with the hinge pin 262 as the central axis to open the opening 241.

[0050] Similarly, when closed, the L-shaped cover 26 flips backward with the hinge pin 262 as the central axis. The top wall 26b of the L-shaped cover 26 covers the open opening 241, but the front wall 26a is spaced apart from the open opening 241 (e.g., Figure 9 (As shown), then push the L-shaped cover 26 backward to slide it, so that the hinge 262 slides backward from the open position of the hinge groove 252 to the closed position. At this time, the L-shaped cover 26 completely closes the open opening 241. At the same time, the threaded hole 265 on the L-shaped cover 26 is aligned with the connecting through hole 253. Finally, screw in the bolt through the connecting through hole 253 and the threaded hole 265 to complete the closing of the L-shaped cover 26.

[0051] Furthermore, the front wall 26a of the L-shaped box cover 26 is also provided with a display screen 106. Example 2:

[0052] Example 2 differs from Example 1 in that: See Figure 4 As shown, the fluid disturbance device is a circulating water pump 9, and the impeller 91 inside the circulating water pump 9 constitutes a disturbance structure; the cold water storage tank 5 is provided with an outlet 502 and an inlet 503 that connect to the cold water chamber 501; the pumping end of the circulating water pump 9 is connected to the outlet 502, and its outlet end is connected to the inlet 503; after the circulating water pump 9 pumps away the cold water stored liquid in the cold water chamber 501, it is discharged back into the cold water chamber 501, so that the cold water stored liquid can flow, thereby achieving water temperature balance.

[0053] The aforementioned outlet 502 and inlet 503 can be opened vertically or horizontally on the same wall of the cold water storage tank 5, or respectively on the opposite wall of the cold water storage tank 5, thereby maximizing the flow effect of the cold storage liquid.
