[0044] The technical scheme of the utility model is further illustrated below by specific implementation manners in combination with the drawings.

[0045] Referring to Figures 1 to 11 The embodiment provides an ice making device, which comprises a shell 10, an ice box structure 20 and an ice making structure 30. The shell 10 has a containing cavity 11. The ice box structure 20 comprises an ice box body 21 and a driving assembly 23. The ice box body 21 is arranged in the containing cavity 11 and has an ice making cavity 211 in the form of an open mouth. The driving assembly 23 is used for driving the ice box body 21 to rotate between an ice making position and an ice removing position. The ice making structure 30 comprises an ice making piece 31, a semiconductor refrigerating piece 32 and a heat sink 33. At least part of the ice making piece 31 is located in the ice making cavity 211. One side of the semiconductor refrigerating piece 32 is matched with the ice making piece 31, and the other side of the semiconductor refrigerating piece 32 is matched with the heat sink 33. The semiconductor refrigerating piece 32 can transfer heat or cold to the ice making piece 31 under different power-on states.

[0046] When the ice box body 21 is located at the ice making position, the semiconductor refrigerating piece 32 transfers cold to the ice making piece 31, so that water at low temperature is attached to the ice making piece 31 to form ice. At the same time, the heat sink 33 takes away the heat of the semiconductor refrigerating piece 32, so that the ice making and ice removing processes are realized. When the ice is removed, the driving assembly 23 needs to drive the ice box body 21 to rotate to the ice removing position, and the semiconductor refrigerating piece 32 also needs to be reversely inputted with current, so that the semiconductor refrigerating piece 32 transfers heat to the ice making piece 31, and the heat is conducted to the ice making piece 31 to realize the heating and ice removing process. Since the ice box body 21 can rotate between the ice making position and the ice removing position, the ice box body 21 can avoid interfering with the ice removing process. Since the semiconductor refrigerating piece 32 is adopted, the heat or cold transferred by the semiconductor refrigerating piece 32 to the ice making piece 31 can be changed by changing the power-on state, so that the space occupation is reduced and the cost is lowered.

[0047] Wherein, when deicing, the driving assembly 23 drives the ice box body 21 to rotate to the deicing position, and the current is reversely input to the semiconductor refrigeration piece 32, which can be performed simultaneously or sequentially. The current can be reversely input to the semiconductor refrigeration piece 32 first, and then the driving assembly 23 drives the ice box body 32 to rotate to the deicing position, or the current can be reversely input to the semiconductor refrigeration piece 32 first, and then the driving assembly 23 drives the ice box body 32 to rotate to the deicing position. The execution sequence and time interval are not limited herein, as long as the ice box body 21 does not interfere with deicing.

[0048] In the embodiment, the semiconductor refrigeration piece 32 cooperates with the ice box body 21 to adopt static water ice making, and the ice box structure 20 further comprises a first water supply assembly 22 for injecting water into the ice making cavity 211. Since at least part of the ice making piece 31 is located in the ice making cavity 211, the water injected into the ice making cavity 211 can fully contact the ice making piece 31, increase the contact area, and enable the cold energy to be fully transferred in the static water during ice making, so that the water is condensed into ice on the ice making piece 31, thereby improving the ice making efficiency.

[0049] In other embodiments, the semiconductor refrigeration piece 32 cooperates with the ice box body 21 to adopt dynamic water ice making, and the ice box structure 20 further comprises a first water supply assembly 22 for spraying water to the ice making piece 31. The first water supply assembly 22 can spray water to the ice making piece 31 from one side of the ice making piece 31, or spray water to the ice making piece 31 upward from below the ice making piece 31. Since at least part of the ice making piece 31 is located in the ice making cavity 211, part of the water forms ice on the ice making piece 31, and the water that does not form ice flows along the ice making piece 31 to the ice making cavity 211 and is stored in the ice making cavity 211. The water stored in the ice making cavity 211 can contact the ice making piece 31 to further form ice, thereby improving the ice making efficiency.

[0050] Wherein, the ice making cavity 211 can store water during ice making, and the ice blocks are condensed on the ice making piece 31. Alternatively, part of the ice blocks are stored in the ice making cavity 211 after being separated from the ice making piece 31, and the ice making piece 31 continues to make ice, and the ice making cavity 211 plays a role of ice storage.

[0051] The shell 10 is open at the top of the shell 10, so as to facilitate water and ice collection at the bottom of the shell 10. The shape of the shell 10 can be set according to actual needs. In the embodiment, the shell 10 is cuboid-shaped, which is convenient for processing and production. A cover plate can be arranged at the top opening of the shell 10 to cover the accommodation cavity 11, so as to prevent impurities from entering the inside of the ice box body 21.

[0052] The water receiving box 40 is located below the ice box body 21, and the top of the water receiving box 40 is provided with an ice guide plate 41 to guide the ice cubes to slide to the ice receiving box 50. The ice guide plate 41 is provided with a water leakage hole 42 in communication with the water receiving box 40. When ice needs to be removed, the driving assembly 23 drives the ice box body 21 to rotate to the ice removal position, and the water in the ice box body 21 flows out and flows to the ice guide plate 41 under the action of gravity. Since the ice guide plate 41 is provided with the water leakage hole 42, the water flows into the water receiving box 40. By reversely inputting current to the semiconductor refrigeration element 32, the semiconductor refrigeration element 32 transmits heat to the ice making element 31, and the heat is conducted to the ice making element 31 to achieve heating and ice removal. The ice cubes slide along the ice guide plate 41 to the ice receiving box 50. In other embodiments, the ice receiving box 50 can be slidingly connected with the shell 10. After the water in the ice box body 21 flows into the water receiving box 40, the ice receiving box 50 slides to the top of the water receiving box 40 to facilitate ice receiving.

[0053] In some embodiments, the water receiving box 40 and the ice receiving box 50 are arranged side by side at the bottom of the accommodation cavity 11, the ice box body 21 is located above the water receiving box 40, and the ice guide plate 41 is inclinedly arranged with the low end of the ice guide plate 41 located at one side of the ice receiving box 50. In some embodiments, the water receiving box 40 is arranged in an L shape at the bottom of the accommodation cavity 11, the ice receiving box 50 is located at the step surface of the water receiving box 40, and the ice guide plate 41 is inclinedly arranged with the low end of the ice guide plate 41 located at one side of the ice receiving box 50.

[0054] In some embodiments, the ice receiving box 50 is slidingly connected with the shell 10 to facilitate taking out the ice receiving box 50. For example, the ice receiving box 50 is pullably arranged in the shell 10 to facilitate pulling out the ice receiving box 50 to take ice. In some embodiments, the water receiving box 40 is integrally formed with the shell 10 to facilitate processing and production.

[0055] The ice box body 21 has an ice making cavity 211 in an open shape. The shape of the ice box body 21 can be set according to actual needs, such as a cuboid, a semi-cylindrical shape, or a semi-elliptical cylindrical shape. In this embodiment, the ice box body 21 is in a semi-cylindrical shape to facilitate water flowing out of the ice box body 21.

[0056] When the ice box body 21 is located at the ice making position, the opening of the ice making cavity 211 faces upward. When the driving assembly 23 drives the ice box body 21 to rotate to the ice removal position, the opening of the ice making cavity 211 faces one side or is inclined downward. In this embodiment, the rotation speed angle of the ice box body 21 from the ice making position to the ice removal position is between 80° and 180°. Preferably, the rotation speed angle of the ice box body 21 from the ice making position to the ice removal position is between 90° and 120°.

[0057] In the present embodiment, the ice box body 21 is rotatably connected with the housing 10. In other embodiments, the ice box body 21 is rotatably arranged on a support, which is located in the housing 10. Exemplarily, both ends of the ice box body 21 are provided with rotating shafts 212, one of which is rotatably connected with the housing 10, and the other is connected with the driving assembly 23. In some embodiments, the driving assembly 23 comprises a motor, which is connected with the rotating shaft 212 to drive the ice box body 21 to rotate. In some embodiments, the driving assembly 23 comprises a motor and a transmission mechanism, which is arranged between the motor and the rotating shaft 212, and the motor drives the transmission mechanism to move to drive the rotating shaft 212 to rotate. The transmission mechanism can adopt a gear mechanism. The motor can adopt a stepping motor.

[0058] The first water supply assembly 22 is used to supply water into the ice making cavity 211. Exemplarily, the first water supply assembly 22 comprises a first water pump 221 and a first water supply pipe 222, one end of which is connected with the first water pump 221, and the other end of which is located in the ice making cavity 211. When it is needed to fill water into the ice box body 21, the first water pump 221 is turned on to guide water flow along the first water supply pipe 222 into the ice making cavity 211. Optionally, a flow meter is arranged on the first water supply pipe 222 to monitor the flow of water filled into the ice box body 21, so as to stop filling water in time. Optionally, a liquid level sensor is arranged in the ice box body 21 to monitor the liquid level in the ice box body 21, so as to stop filling water in time. Even if part of the water overflows from the top edge of the ice making cavity 211, the overflowing water can flow into the water receiving box 40, without affecting ice making.

[0059] The ice making piece 31 can adopt a metal piece that is convenient for heat transfer, such as an aluminum piece or a stainless steel piece. In the present embodiment, the ice making piece 31 comprises a plurality of ice making columns 311, one end of which away from the semiconductor refrigeration piece 32 is located in the ice making cavity 211.

[0060] In some embodiments, as shown in Figure 12 The ice making column 311 is in a columnar structure, and the ice is solidified on the outer surface of the ice making column 311 during ice making. The plurality of ice making columns 311 can simultaneously form a plurality of ice blocks, and since the plurality of ice making columns 311 are all in a columnar structure, the ice blocks formed on the plurality of ice making columns 311 are all in a bullet shape. The ice making column 311 can be a solid structure or a hollow structure. When the ice making column 311 is a hollow structure, a medium with good heat conduction performance, such as a graphene liquid or a solid graphite rod, can be filled in the inside of the ice making column 311.

[0061] In some embodiments, as shown in Figures 7 to 9As shown, the inside of the ice making column 311 is hollow to form an ice containing cavity 3111, and the end of the ice making column 311 away from the semiconductor refrigeration piece 32 is provided with an opening in communication with the ice containing cavity 3111. The water in the ice making cavity 211 can enter the ice containing cavity 3111 through the opening, so that the inside and outside of the ice making column 311 have water, and thus the inside and outside of the ice making column 311 can make ice at the same time during ice making, thereby increasing the ice making area and the ice making amount. Since the ice containing cavity 3111 is arranged on the ice making column 311, the ice making column 311 has a ring-shaped cylindrical structure. The ring-shaped wall of the ice making column 311 can be a solid structure or a hollow structure. When the ring-shaped wall of the ice making column 311 is a hollow structure, the inside of the ring-shaped wall of the ice making column 311 can be filled with a medium with good heat conduction performance, such as graphene liquid or a solid graphite rod.

[0062] The outer surface of the ice making column 311 is in a cylindrical shape or a reverse conical shape; and / or, the side wall of the ice containing cavity 3111 is in a cylindrical shape or a reverse conical shape. In some embodiments, the outer surface of the ice making column 311 is in a reverse conical shape, and the side wall of the ice containing cavity 3111 is in a reverse conical shape. The reverse conical surface can guide the ice to be removed quickly.

[0063] The ice making piece 31 further comprises an ice making plate 312, which is attached to the semiconductor refrigeration piece 32 to increase the contact area and improve the heat transfer efficiency. The plurality of ice making columns 311 are arranged on the ice making plate 312 in a spaced manner. The plurality of ice making columns 311 can be arranged in a matrix, or two adjacent rows of ice making columns 311 can be arranged alternately, so as to maximize the number of ice making columns 311 arranged on the ice making plate 312 and improve the ice making efficiency. The ice making plate 312 and the heat sink 33 can be locked by a locking piece. Exemplarily, the locking piece is a bolt.

[0064] Optionally, the semiconductor refrigeration piece 32 comprises a plurality of semiconductor refrigeration pieces, each of which has a first side and a second side arranged oppositely, the first side is attached to the heat sink 33, and the second side is attached to the ice making piece 31. In different power-on states, one of the first side and the second side is a hot end and the other is a cold end. During ice making, the second side is a cold end to transfer cold to the ice making piece 31, and the first side is a hot end to transfer heat away by the heat sink 33. During ice removal, the second side is a hot end to transfer heat to the ice making piece 31 to facilitate ice removal, and the first side is a cold end to transfer cold away by the heat sink 33.

[0065] The heat sink 33 is flat and adheres to the semiconductor refrigeration element 32 to increase the contact area between the heat sink 33 and the semiconductor refrigeration element 32 and improve the heat dissipation efficiency. The heat sink 33 is cooled by water, and the heat sink 33 has a water inlet 331 and a water outlet 332. In a conventional arrangement, a circulating pump is used to drive the water flow into the heat sink 33 from the water inlet 331 and out of the heat sink 33 from the water outlet 332. The water flow out of the water outlet 332 is then driven by the circulating pump into the heat sink 33 from the water inlet 331 to achieve water circulation. Because the water flow is circulated, the heated water is used multiple times, and the heat dissipation effect is reduced.

[0066] In this embodiment, the ice making structure 30 further includes a second water supply assembly 34. The interior of the heat sink 33 forms a water flow channel, and the second water supply assembly 34 can continuously guide the water flow to pass through the water flow channel in a single pass and be discharged. The water flow passes through the water flow channel in a single pass and is not recycled, that is, the water flow enters the heat sink 33 from the water inlet 331 and flows out of the heat sink 33 from the water outlet 332, and the water flow out of the water outlet 332 will not enter the heat sink 33 from the water inlet 331. The water flow is not circulated, and after flowing through the heat sink 33, it is directly discharged. A sufficient water source is needed to continuously supply water to the water inlet 331. During the process of the water flow passing through the water flow channel, the water flow carries away heat so that the heated water is discharged, ensuring the heat dissipation effect.

[0067] Exemplarily, the second water supply assembly 34 includes a water inlet valve and a water outlet valve. The water inlet valve is arranged upstream of the water inlet 331, and the water outlet valve is arranged downstream of the water outlet 332. In use, both the water inlet valve and the water outlet valve are opened, and the water pressure of the water inlet is used to make the water flow into the heat sink 33 from the water inlet 331 and flow out of the heat sink 33 from the water outlet 332. Exemplarily, the second water supply assembly 34 includes a second water pump 341 and a second water supply pipe 342. One end of the second water supply pipe 342 is connected to the second water pump 341, and the other end of the second water supply pipe 342 is in communication with the water inlet 331 of the heat sink 33. When heat dissipation is needed, the second water pump 341 is started to guide the water flow into the heat sink 33 along the second water supply pipe 342.

[0068] The water flow channel in the heat sink 33 is bent and extended to increase the heat dissipation area. Exemplarily, the water flow channel is S-shaped or reciprocatingly bent and extended. In this embodiment, the heat sink 33 includes a first cover plate 333 and a second cover plate 334 that are detachably connected. The first cover plate 333 and the second cover plate 334 enclose a heat dissipation cavity, and a plurality of fins 335 are arranged in the heat dissipation cavity in a spaced manner. The plurality of fins 335 enclose a reciprocatingly bent water flow channel. Through the detachable connection, the heat sink 33 is convenient to install, disassemble and maintain.

[0069] Optionally, as Figure 10As shown, multiple fins 335 are arranged in parallel and spaced apart within the heat dissipation cavity. One end of each fin 335 is sealed to the inner wall of the heat dissipation cavity, while the other end is spaced apart from the inner wall to form flow guides 337. These flow guides 337 are arranged alternately on opposite sides of the heat dissipation cavity. Water entering from the inlet 331 flows along the fins 335 to the flow guides 337, sequentially passing through both sides of each fin 335 and exiting from the outlet 332. The more fins 335 there are, the more tortuous the water flow channel becomes, thus extending the residence time of the water within the channel and improving heat exchange efficiency.

[0070] Optionally, such as Figure 11 As shown, multiple fins 335 are arranged in parallel and spaced apart within the heat dissipation cavity. One end of some fins 335 is sealed to the inner wall of the heat dissipation cavity to form a flow guide fin 3351, and the other end of the flow guide fin 3351 is spaced apart from the inner wall of the heat dissipation cavity to form a flow guide port 337. Multiple flow guide ports 337 are arranged alternately on opposite sides of the heat dissipation cavity. Both ends of some fins 335 are spaced apart from the inner wall of the heat dissipation cavity to form a flow divider fin 3352. A flow divider fin 3352 is provided between two adjacent flow guide fins 3351. By setting the flow divider fin 3352, the water flow is divided into at least two paths when flowing between adjacent flow guide ports 337. The contact between the water flow and the flow divider fin 3352 increases the heat exchange area and improves the heat exchange efficiency.

[0071] The first cover plate 333 and the second cover plate 334 can be locked together by a locking member. Exemplarily, the locking member is a conventional bolt. A sealing ring 336 is provided between the first cover plate 333 and the second cover plate 334 to ensure the airtightness of the heat dissipation cavity. Exemplarily, the second cover plate 334 has a mounting groove, into which the sealing ring 336 is inserted and abuts against the first cover plate 333.

[0072] Exemplarily, the first cover plate 333 is attached to the semiconductor cooling element 32, and the fins 335 are integrally formed with the first cover plate 333. The first cover plate 333 and the fins 335 can be made of metal to improve heat transfer efficiency. For example, aluminum or stainless steel. Exemplarily, the second cover plate 334 is made of plastic to reduce weight.

[0073] The heat sink 33 can also be cooled by a fan. In other embodiments, the heat sink 33 may be a heat pipe type heat sink.

[0074] This embodiment also provides a water purifier, including a body and the aforementioned ice-making device. A filter assembly is disposed within the body, and the outer casing 10 is located within the body. The purified water inlet of the filter assembly can be connected to the first water pump 221 of the first water supply assembly 22, so that the water used for ice making is purified water.

[0075] In some embodiments, the waste water outlet of the filter assembly is used to supply water to the radiator 33 so that the waste water is fully utilized. Exemplarily, the waste water outlet of the filter assembly can supply the waste water that has passed through the radiator 33 once to the radiator 33. The waste water can flow through the radiator 33 by using its own water pressure or gravity, or the second water supply assembly 34 can guide the waste water to pass through the water flow channel of the radiator 33 once and be discharged. Since the waste water is not generated in real time, a waste water tank can be arranged so that the waste water is stored in the waste water tank, and when ice is made, the waste water flows through the radiator 33 under the action of gravity, or the second water supply assembly 34 guides the waste water in the waste water tank to pass through the water flow channel of the radiator 33 once and be discharged.

[0076] The above embodiments only illustrate the basic principles and characteristics of the present application, and the present application is not limited to the above embodiments. Without departing from the spirit and scope of the present application, various changes and modifications can be made to the present application, and these changes and modifications all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
