[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] (1) The water dispenser can use an external water source to supply water to the ice-making device, and can also add water into the water supply tank for water supply. It uses two water supply methods to supply water, which has more water supply methods, relies on gravity to supply water, has a simple structure and low cost;

[0023] (2) The pumping device pumps the water in the chamber into the water storage chamber, and the ice making device can make ice from the water in the water storage chamber. During the ice making process, the pumping device keeps supplying water to the water storage chamber, and the water in the water storage chamber flows back into the chamber. During this process, the water level is kept full, ensuring that the water in the water storage chamber keeps flowing during the ice making process, taking away the air dissolved in the water, thereby avoiding gaps in the made ice. The pumping device can also pump the water in the chamber to the outside for use by users.

[0024] (3) Since the air dissolved in water is generally on the water surface, the upper water outlet, in addition to draining water, is mainly used to take away the air dissolved in the water. The lower water outlet is used to drain water so that the water can circulate. When defrosting, the water in the ice box needs to be drained through the lower water outlet. When defrosting, the ice box rotates to prevent water from pouring into the ice basket.

[0025] (4) The rotating device drives the ice box to rotate, so that the ice box rotates to the side of the ice making component. At this time, the ice box is in an ice-removing state, and the ice box will not affect the ice cubes from falling off the ice making component;

[0026] (5) The water inlet and the upper water outlet are located at the two ends of the water storage cavity, and the lower water outlet and the upper water outlet are located at the same end, so that water can enter from one end of the ice box and exit from the other end, so that the water can circulate better;

[0027] (6) During the defrosting process, the compressor, fan, and defrosting solenoid valve work. When the ice making time is reached, the centrifugal pump stops working, and the ice making box moves to the defrosting state. At the same time, the defrosting solenoid valve works and stops working after working for T (preset 10S) seconds. The defrosting solenoid valve can increase the temperature of the evaporator, thereby facilitating the ice cubes to fall off the evaporator.

[0028] (7) When the ice is full, the machine stops making ice, and the compressor and fan stop working. The compressor and fan are started at a fixed time to keep the ice warm. During the warming process, the ice box moves to the de-icing state, and the centrifugal pump does not work;

[0029] (8) When the ice-making step reaches the maximum ice time, the compressor stops working, and the fan and pumping device on the condenser continue to work. At the same time, the cold water temperature at the bottom of the box is detected. When the cold water temperature at the bottom of the box no longer continues to drop, the compressor starts and enters the next maximum ice working time. This cycle continues until the refrigeration stop temperature is reached. It has both ice-making and cooling water functions, and the two functions are integrated;

[0030] (9) When the ice-making step reaches the maximum ice time, the compressor stops working, and the fan and pumping device on the condenser continue to work. At the same time, the cold water temperature at the bottom of the box is detected. When the cold water temperature at the bottom of the box no longer continues to drop, the compressor starts and enters the next maximum ice working time. This cycle continues until the refrigeration stop temperature is reached. It has both ice-making and cooling water functions, and the two functions are integrated together.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] See also Figure 1-Figure 8 The utility model provides a technical solution for a water dispenser.

[0042] A water dispenser, comprising:

[0043] A water supply device, the water supply device includes a water supply pump 28, a water supply tank 25 and a water supply inlet valve 24, the water supply pump 28 includes a water supply pump inlet 29 and a water supply pump outlet 30, the water supply pump inlet 29 is connected to an external water source, the water supply pump outlet 30 is connected to the water supply tank 25, the water supply inlet valve 24 includes a water supply inlet valve inlet 10 and a water supply inlet valve outlet 11, the water supply inlet valve inlet 10 is connected to the water supply tank 25, and the height of the water supply inlet valve 24 is lower than the water supply tank 25;

[0044] The ice-making device comprises an ice-making water inlet 26 , which is connected to the water supply inlet valve outlet 11 , and the ice-making water inlet 26 is not higher than the water supply inlet valve outlet 11 .

[0045] By adopting the above method, the ice-making device can be supplied with water from an external water source, and water can be added to the water supply tank 25 for water supply. Two water supply methods are used for water supply, and more water supply methods are provided. When external water supply is adopted, a pipeline can be connected to the water supply pump inlet 29 of the water supply pump 28, and then the pipeline is connected to an external mineral water barrel. The water supply pump 28 can pump water in the external mineral water barrel into the water supply tank 25, so that the water supply tank 25 is filled with water. When water needs to be added to the ice-making device, the water supply inlet valve 24 is opened, and the water in the water supply tank 25 flows into the ice-making device after passing through the water supply inlet valve 24 and the ice-making water inlet 26 due to the action of gravity, thereby supplying water to the ice-making device. Closing the water supply inlet valve 24 will stop the water inlet, which is easy to control, relies on gravity to inlet water, has a simple structure, and is low in cost.

[0046] Ice making device, comprising:

[0047] A box body 1, wherein a cavity 2 is provided in the box body 1;

[0048] An ice-making structure, the ice-making structure comprises an ice-making component, and the ice-making component is installed in the chamber 2;

[0049] An ice box 3 is provided with a water-containing cavity 4, and an ice-making component is located on the water-containing cavity 4;

[0050] A water delivery device, which delivers water into the chamber 2;

[0051] The pumping device pumps the water in the cavity 2 into the water-containing cavity 4 and pumps the water in the cavity 2 to the outside.

[0052] The water delivery device delivers water to the chamber 2, and the water pumping device pumps the water in the chamber 2 into the water holding chamber 4. The ice making device can make ice from the water in the water holding chamber 4. During the ice making process, the water pumping device keeps supplying water to the water holding chamber 4. After the water in the water holding chamber 4 is full, it flows back into the chamber 2. During this process, the water level is kept full, ensuring that the water in the water holding chamber 4 keeps flowing during the ice making process, taking away the air dissolved in the water, thereby avoiding gaps in the made ice.

[0053] A water level sensor 27 is installed in the chamber 2. The water level sensor 27 is used to measure the water level in the chamber 2. The high water level signal and the low water level signal of the lower water level of the chamber 2 can be obtained to control water replenishment. When the water level is low, water is preferentially replenished into the box body 1.

[0054] like Figure 5 As shown, the ice box 3 is rotatably connected to the box body 1, and a rotating device 5 is fixed on the box body 1 to drive the ice box 3 to rotate, and also includes an ice basket 6, which is arranged below the ice box 3, and is provided with an ice storage groove 7 with an opening facing the ice box 3, and an opening is also provided on the side wall of the ice basket 6. The ice basket 6 can receive ice cubes that fall off from the ice making component.

[0055] The ice box 3 is in the ice making state position (such as Figure 5 When ice making is completed and ice needs to be taken out, the rotating device 5 drives the ice box 3 to rotate, so that the ice box 3 rotates to the side of the ice making component. At this time, the ice box 3 is in the ice-shedding state, and the ice box 3 will not affect the ice cubes from falling off the ice making component. The side wall of the ice basket 6 is also provided with an opening. The ice basket 6 can receive the ice cubes falling off the ice making component.

[0056] like Figure 5-Figure 7 As shown, an upper water outlet 8 is provided on the side wall of the ice making box 3, and the upper water outlet 8 is located outside the ice basket 6. Since the air dissolved in the water is generally on the water surface, the upper water outlet 8, in addition to drainage, mainly serves to take away the air dissolved in the water.

[0057] Furthermore, a lower water outlet 9 is provided on the side wall of the ice box 3, and the lower water outlet 9 is located outside the ice basket 6. The lower water outlet 9 is used to drain water so that water can circulate, including when defrosting, the water in the ice box 3 needs to be drained through the lower water outlet 9, and when defrosting, the ice box 3 rotates so that water will not be poured into the ice basket 6.

[0058] like Figure 5-Figure 7As shown, since the upper water outlet 8 is located on the outside of the ice basket 6 and the lower water outlet 9 is located on the outside of the ice basket 6, the water flowing out from the upper water outlet 8 and the lower water outlet 9 will directly flow to the lower part of the cavity 2, preventing the water from flowing into the ice basket 6 and affecting the ice cubes in the ice basket 6, thereby preventing the ice cubes from sticking together.

[0059] like Figure 5-Figure 7 As shown, a water inlet hole 23 is provided on the upper side of the box body 1, and the water pumping device pumps water into the water holding cavity 4 through the water inlet hole 23. The water inlet hole 23 and the upper water outlet 8 are respectively located at the two ends of the water holding cavity 4, and the lower water outlet 9 and the upper water outlet 8 are located at the same end. Thus, water can enter from one end of the ice box 3 and exit from the other end, so that the water can circulate better. The water inlet hole 23 is connected to a water inlet pipeline 31, and water is transported to the water holding cavity 4 through the water inlet pipeline 31.

[0060] like Figure 1 As shown, the ice-making component is configured as an evaporator 12, and the ice-making structure also includes a compressor 13, a condenser 14, a capillary tube 15 and a liquid reservoir 16. The compression outlet of the compressor 13 is connected to the condensation inlet of the condenser 14, the condensation outlet of the condenser 14 is connected to the capillary inlet of the capillary tube 15, the capillary outlet of the capillary tube 15 is connected to the evaporation inlet of the evaporator 12, the evaporation outlet of the evaporator 12 is connected to the liquid storage inlet of the liquid reservoir 16, and the liquid storage outlet of the liquid reservoir 16 is connected to the compression inlet of the compressor 13; a drying filter 21 is connected between the condenser 14 and the capillary tube 15, and a fan 20 is installed on the condenser 14.

[0061] like Figure 1 As shown, the ice-making structure further includes an ice-defrosting electromagnetic valve 17 , the compression outlet of the compressor 13 is connected to the ice-defrosting inlet of the ice-defrosting electromagnetic valve 17 , and the ice-defrosting outlet of the ice-defrosting electromagnetic valve 17 is connected to the evaporation inlet of the evaporator 12 .

[0062] Defrosting: During the defrosting process, the compressor 13, the fan 20 and the defrosting solenoid valve 17 work. After the ice making time is reached, the centrifugal pump 18 stops working, and the ice making box 3 moves to the defrosting state position. At the same time, the defrosting solenoid valve 17 works and stops working after working for T (preset 10S) seconds. When the defrosting solenoid valve 17 works, the temperature of the evaporator 12 can be increased, thereby facilitating the ice cubes to fall off the evaporator 12.

[0063] like Figure 1 As shown, the pumping device includes a centrifugal pump 18 and a three-way valve 19. One end of the centrifugal pump 18 is connected to the bottom of the box body 1, and the other end is connected to the three-way first interface of the three-way valve 19. The three-way second interface of the three-way valve 19 is connected to the water inlet hole 23 on the upper side of the box body 1. The third interface of the three-way valve 19 discharges cold water, thereby pumping the cold water to the outside for users to use.

[0064] The centrifugal pump 18 can pump water in the box 1 into the water storage cavity 4, and then the water returns to the chamber 2 of the box 1 through the water storage cavity 4, and can also take out the ice water produced in the box 1 from the third interface. A water level sensor 27 and a temperature sensor are installed in the box 1 to detect the water level and the temperature.

[0065] Furthermore, if Figure 6 As shown, a slot 22 is provided on the side wall of the box body 1, and the ice basket 6 is plugged into the slot 22. The ice basket 6 can be taken out by pulling, which is very convenient.

[0066] An ice making method based on the above water dispenser comprises the following steps:

[0067] Reset waiting, before ice making starts, the ice box 3 runs to the ice-removing state position, then the compressor 13 and the fan 20 on the condenser 14 are started, and at the same time the ice box 3 starts to run to the ice making state position;

[0068] Inject water, the centrifugal pump 18 starts to work, injecting water into the ice box 3 for circulation;

[0069] Ice making, the ice making process keeps the compressor 13, the fan 20 and the circulation pump working;

[0070] Deicing: During the deicing process, the compressor 13, the fan 20, and the deicing solenoid valve 17 work. When the ice making time is reached, the centrifugal pump 18 stops working, and the ice making box 3 moves to the deicing state position. At the same time, the deicing solenoid valve 17 works and stops working after working for T seconds;

[0071] In the next ice making cycle, the ice-removing solenoid valve 17 stops working after ice-removing is completed, and when the ice-making box 3 runs to the ice-making state position, the centrifugal pump 18 starts working and enters the next ice making cycle until the ice storage box is full of ice and stops refrigeration, and the ice-making box 3 is reset to the ice-removing state position.

[0072] It also includes an ice-full insulation state. When the ice is full, the machine stops making ice, and the compressor 13 and the fan 20 stop working. The compressor 13 and the fan 20 are started at a fixed time to keep the ice warm. During the insulation process, the ice box 3 runs to the ice-removing state position, and the centrifugal pump 18 is not working.

[0073] A refrigeration method based on the above water dispenser comprises the following steps:

[0074] Ice making step: in the ice making state, the compressor 13, the fan 20 on the condenser 14, and the water pumping device keep working;

[0075] Refrigeration step, ice making step takes precedence over refrigeration step, when ice making step reaches the maximum ice time, compressor 13 stops working, fan 20 and pumping device on condenser 14 continue to work, and detects the cold water temperature at the bottom of cabinet 1 at the same time, when the cold water temperature at the bottom of cabinet 1 no longer continues to drop, compressor 13 starts and enters the next maximum ice working time, and repeats this cycle until the refrigeration stop temperature is reached.
