[0028] The utility model is described in detail below in combination with the drawings and examples.

[0029] The utility model provides a kind of ice block adhesion prevention ice making module, as shown in Figures 1-8 Ice water tank 1 is arranged in ice water tank 1, and ice block storage tank 2 is arranged in ice water tank 1, ice water tank 1 is rotatably arranged in ice water tank 1, and ice making tank 3 is arranged in ice water tank 1, ice water tank 1 is provided with ice turning motor 6 for driving ice making tank 3 reciprocating rotation and then ice block is thrown into ice block storage tank 2;Ice block storage tank 2 is provided with ice outlet 21, ice water tank 1 is provided with ice outlet motor 7, and spring ice conveying screw rod 8 for conveying ice block in ice block storage tank 2 to ice outlet 21 is arranged on the output shaft of ice outlet motor 7;Ice water tank 1 is provided with ice outlet channel 14 communicated with ice outlet 21;Ice water tank 1 is provided with ice melting nozzle 17 for spraying hot water to ice block in ice block storage tank 2.

[0030] In this embodiment, the ice water tank 1 has an upper ice water inlet 11 at its upper end, a lower ice water inlet (not shown in the drawings) at its middle end, and an ice water outlet (not shown in the drawings) at its lower end. The ice water outlet is connected to the water inlet of a micro-ice water pump (not shown in the drawings) via one end of a tee and a conduit. The ice water outlet is connected to the ice water outlet of a water dispenser via the other end of the tee and a conduit. The lower ice water inlet is connected to the water outlet of the refrigeration module via a conduit, thereby directing the ice water produced by the refrigeration module into the ice water tank 1. The upper ice water inlet 11 is connected to the water outlet of the micro-ice water pump via a conduit. An ice storage trough 2 is overlapped at a lower position within the ice water tank 1 by a retaining structure. An ice making trough 3 is rotatably disposed above the ice storage trough 2. The ice making trough 3 has a rotating shaft at each end and is mounted on the ice water tank 1 via corresponding pin-hole structures, allowing the ice making trough 3 to rotate within a certain angle range within the ice water tank 1. The ice turning motor 6 is a stepping motor, which is fixed to the side wall of the ice water tank 1 by screws. Its output shaft is relatively fixed with the rotating shaft of the ice making groove 3 through a clamping structure to achieve transmission connection. Of course, the transmission connection can also be achieved according to the existing transmission method.

[0031] The ice storage tank 2 is a tank body with an inclined bottom surface. The horizontal height of its right end (ice outlet 21 end) is higher than that of its left end to facilitate the transportation of ice cubes. The second ice water reflux hole 22 at the bottom is located at the leftmost end of the bottom of the ice storage tank 2. It can transport the ice water generated by the melting of some ice cubes in the ice storage tank 2 to the ice water tank 1, slowing down the heating rate of the ice water in the ice water tank 1 and saving energy consumption to a certain extent.

[0032] The right end of the spring-loaded ice-discharging screw 8 is threadedly fixed to the output shaft of the ice-discharging motor 7, while its left end is inserted into the positioning hole in the ice storage trough 2. The ice-discharging motor 7 is a reduction motor and is screwed to the side wall of the ice water tank 1. The ice-discharging motor 7 drives the spring-loaded ice-discharging screw 8 to rotate, thereby transporting the ice cubes in the ice storage trough 2 to the ice outlet 21, the ice outlet channel 14, and finally, under the action of gravity, into the ice receiving container.

[0033] The water blowing end of the ice melting nozzle 17 is inserted into the pin hole on the ice water tank 1, and the water inlet end is fixed on the ice water tank 1 by screws or interference fit. Figure 8 Hot water (about 50°C-80°C) in the ice storage tank (as shown by the arrow C) is sprayed on the ice cubes in the ice storage tank 2 at regular time intervals, so that the outer edges of the ice cubes that are stuck together are melted, thereby resolving the problem of ice cube adhesion, so that the ice cubes will not be stuck in the ice outlet, and ice cubes can be discharged normally when the user needs them.

[0034] Furthermore, a baffle 12 is hinged in the ice outlet channel 14 for movably preventing pollutants from entering the ice storage tank 2 from the external environment through the ice outlet channel 14 , and a driving member 13 is provided on the ice water tank 1 for driving the baffle 12 to movably block the ice outlet channel 14 .

[0035] like Figure 5 As shown, a baffle 12 is hingedly connected to the ice outlet duct 14 approximately in the middle of the ice outlet duct 14 via a pin-hole structure. A driver 13 is screwed to the outer side of the ice water tank 1, and its output shaft is fixedly connected to the pin on the baffle 12 through an interference fit. Driven by the driver 13, the baffle 12 flexibly blocks the ice outlet duct. When the ice is not being discharged, the baffle 12 blocks the ice outlet duct 14, preventing contaminants from entering the ice outlet duct 14 and contaminating the ice in the water storage tank 2. Furthermore, the baffle 12, which flexibly blocks the ice outlet duct 14, also effectively reduces the melting rate of the ice in the ice storage tank 2.

[0036] Furthermore, an ice discharge ramp 15 is provided between the ice inlet end and the ice discharge end of the ice discharge channel 14 to facilitate ice cubes to slide into the ice receiving container.

[0037] like Figure 5 As shown, the left end of the ice discharging ramp 15 is higher than the right end and is close to the ice outlet 21. When the spring ice discharging screw 8 pushes the ice cubes, the ice cubes will slide directly from the ice discharging ramp 15 to the ice receiving container. The ice discharging ramp 15 makes the ice cubes fall out more smoothly and will not cause some ice cubes to accumulate at the ice inlet end of the ice discharging ramp 15, thereby solving the problem of ice discharging jam.

[0038] Furthermore, a first ice water reflux hole 151 is provided on the ice discharge ramp 15, and an ice water reflux groove 16 is provided at the bottom thereof for accommodating ice water melted from ice cubes in the ice inlet end of the ice discharge ramp 15. The ice water reflux groove 16 is connected to the ice discharge channel 14 through the first ice water reflux hole 151, and the ice water reflux groove 16 is connected to the ice water tank 1.

[0039] like Figure 5 As shown, the first ice water return hole 151 is located on the lower side of the ice discharge ramp 15. When ice cubes accumulate at the ice inlet end of the ice discharge channel 14 for a long time, some of the ice cubes will melt into ice. This part of the ice water flows along the first ice water return hole 151 into the ice water return trough 16 integrally formed with the ice water tank 1. The bottom of the ice water return trough 16 has a water outlet hole, and the ice water in the ice water return trough 16 is returned to the ice water tank 1 through an external conduit, thereby preventing dripping from the ice discharge channel 14 of the water dispenser. In addition, the ice water return trough 16 can also be detachably installed below the ice discharge ramp 15 using a snap-on structure.

[0040] Furthermore, the driving member 13 is any one of a stepping motor, a reduction motor, and a stepping reduction motor, the fixed end of which is mounted on the outer wall of the ice water tank 1 by screws, and the output shaft thereof is fixedly connected to the baffle 12 .

[0041] Furthermore, an ice-making element 4 is provided inside the ice water tank 1 for making ice cubes from the ice water in the ice-making trough 3; a micro ice water pump (not shown in the drawings) is provided on the ice water tank 1 for transporting the ice water in the ice water tank 1 to the ice-making trough 3, and the water inlet of the micro ice water pump is connected to the ice water tank 1, and its water outlet is connected to the ice-making trough 3; a water receiving trough 5 is provided inside the ice water tank 1 and between the ice storage trough 2 and the ice-making trough 3 for accommodating the ice water overflowing from the ice-making trough 3 and transporting the overflowing ice water to the ice water tank 1, and at least one water outlet hole 51 is provided at the bottom of the water receiving trough 5 for transporting the ice water in the water receiving trough 5 to the ice water tank 1.

[0042] like Figures 3-7 As shown, an ice-making element 4 is inserted above the ice-making trough 3, with its ice-making end extending into the ice-making trough 3. The ice-making element 4 is a commonly used ice-making component in the art. Its cooling end is immersed in liquid water, converting the liquid water into solid ice cubes. It also generates a certain degree of heat, causing the ice cubes to fall from the cooling end into the ice-making trough 3. The detailed structure of the ice-making element 4 can be found in patent CN117597560A. Furthermore, to expedite the drop of ice cubes from the ice-making end of the ice-making element 4, another miniature ice-water pump can be used to spray hot water from the hot water tank in the water dispenser onto the ice-making end of the ice-making element 4, partially melting the ice cubes and allowing them to fall into the ice-making trough 3. A water receiving trough 5 is connected above the ice storage trough 2 via a retaining structure.

[0043] The ice cube and ice water making process of the present invention is as follows: tap water is processed by a filter element to obtain pure water at room temperature, part of the pure water enters the heating module to obtain hot water, and the other part of the pure water enters the cooling module to obtain ice water, and the ice water enters the ice water tank 1 through the lower ice water inlet hole for storage, part of the ice water in the ice water tank 1 flows to the ice water outlet nozzle of the drinking water (which can be directly drunk) through the ice water outlet hole, and the other part of the ice water in the ice water tank 1 enters the ice making trough 3 through the ice water outlet hole, the micro ice water pump and the upper ice water inlet hole 11, and then the ice making element 4 makes ice cubes from the ice water.

[0044] When the temperature of the chilled water in ice water tank 1 reaches a temperature midway between two preset thresholds (for example, if the microcompressor starts at 10°C and stops at 4°C, the midway temperature is 7°C), the micro-chilled water pump activates, pumping the chilled water from ice water tank 1 to ice making trough 3 for heat exchange with the ice cubes. The cooled chilled water overflows from ice making trough 1 and flows back into ice water tank 1 through water receiving trough 5, which has a water outlet 51, thereby lowering the temperature of the chilled water in ice water tank 1. This design reduces the need for frequent activation of the microcompressor. The excess cooling capacity generated by refrigeration element 4 is transferred to the chilled water via the ice cubes, thereby reducing energy consumption and noise generation. Furthermore, when making the next batch of ice cubes, the micro-chilled water pump pumps the chilled water from ice water tank 1 to ice making trough 3 for ice making, resulting in higher ice-making efficiency compared to making ice cubes from room-temperature water.

[0045] Furthermore, an ice blocking plate 31 is hinged on the side wall of the ice making trough 3 to block ice cubes from entering the water receiving trough 5 .

[0046] like Figures 4-8 As shown, to prevent some small ice cubes from falling into the water receiving trough 5 during the ice making trough 3's flipping, an ice shield 31 is hingedly connected to the side wall of the ice making trough 3. The ice shield 31 covers the gap between the ice making trough 3 and the water receiving trough 5. This design prevents some ice cubes from falling into the water receiving trough 5 and affecting the normal reciprocating rotation of the ice making trough 3.

[0047] Furthermore, the protective shell 9 is provided, which is mounted on the lower end of the ice water tank 1. The space between the protective shell 9 and the ice water tank 1 is filled with an insulation layer 10, which is made of foamed insulation material. This design can further slow down the temperature rise rate of the ice water in the ice water tank 1.

[0048] like Figure 8 As shown, the utility model also provides a multifunctional water dispenser, which includes a box body (not shown in the drawings), in which a hot water tank ( Figure 8 The invention also includes an ice making module as shown by the arrow C in the figure, an ice making module for preventing ice cubes from sticking together, and a micro hot water pump (not shown in the figure) for transporting hot water in the hot water tank to the ice melting nozzle; the water inlet of the micro hot water pump is connected to the water outlet of the hot water tank through a conduit, and the water outlet is connected to the water inlet of the ice melting nozzle through a conduit.

[0049] The water path of the multifunctional water dispenser is as follows: tap water enters a raw water tank (installed in the tank body) through a conduit, then enters a booster pump, a composite filter element and a pure water tank in sequence; the pure water in the pure water tank enters an ice water tank 1 after being made into ice water by a refrigeration module, and enters a hot water tank after being made into hot water by a heating module. A one-way valve is installed between the connecting pipeline between the composite filter element and the pure water tank, which only allows the pure water to flow from the composite filter element to the pure water tank, and does not allow the pure water to flow from the pure water tank to the composite filter element. The one-way valve can prevent the pure water in the pure water tank from being sucked back into the composite filter element under the siphon effect when the booster pump stops, thereby avoiding the waste of the pure water.

[0050] The preferred embodiments of the present application have been described above, but the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the technical field, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
