[0002] An ice purifier, also known as an ice-making and water-dispensing machine, is an appliance that purifies water, makes ice, and dispenses water and ice. An ice purifier typically contains an ice storage box beneath the ice mold. Ice cubes are poured directly into the box after being made by the ice mold.

The water purification mechanism 100 can purify water to prepare drinkable pure water and can transport the pure water to the cold water tank 300. The ice making mechanism 200 can make pure water into ice cubes and can transport the ice cubes to the ice crushing mechanism 400. The ice crushing mechanism 400 can further crush the ice cubes made by the ice making mechanism 200 into crushed ice and output it to the user for use. A cold water return flow channel 500 is provided between the ice crushing mechanism 400 and the cold water tank 300, and the cold water return flow channel 500 can guide the water in the ice crushing mechanism 400 to the cold water tank 300. A first cold water flow channel 600 and a second cold water flow channel 700 are respectively provided between the cold water tank 300 and the ice making mechanism 200 and the water purification mechanism 100. The first cold water flow channel 600 and the second cold water flow channel 700 can guide the water in the cold water tank 300 to the ice making mechanism 200 and the water purification mechanism 100 respectively; pure water is prepared by the water purification mechanism 100 and the pure water is transported to the ice making mechanism 200, and the pure water is transported to the ice making mechanism 200 by the ice making mechanism 200. The ice cubes are made and transported to the ice crushing mechanism 400, which further shreds the ice cubes into crushed ice and outputs them to the outside for users to use. Since the ice making mechanism 200 contains ice cubes, and the melted water of the ice cubes in the ice making mechanism 200 also enters the ice crushing mechanism 400 along the ice conveying path, in order to prevent the ice water generated by the melted ice cubes from being stored in the ice making mechanism 200 for too long and affecting the water quality and ice quality in the ice purifier, the water in the ice crushing mechanism 400 is guided to the cold water tank 300 through the cold water return flow channel 500, so that the water in the ice crushing mechanism 400 can be cleaned in time to avoid the ice purifier from being damaged. Bacteria are grown in the cold water tank 300, thereby improving the water quality and ice quality in the ice purifier; in addition, the water in the cold water tank 300 can flow along the first cold water flow channel 600 to the ice making mechanism 200 for secondary ice making, and the water in the cold water tank 300 can also flow along the second cold water flow channel 700 to the water purification mechanism 100 for secondary water purification, so that the water in the cold water tank 300 can be reused, which is beneficial to improving water utilization and reducing water resource waste. Moreover, the water quality and ice quality in the ice purifier can be further improved by performing secondary water purification on the water in the cold water tank 300 through the water purification mechanism 100, so as to avoid the quality of the water in the cold water tank 300 from deteriorating due to being left for too long.

[0035] Specifically, such as Figure 1As shown, the water purification mechanism 100 includes a raw water tank 110 arranged in the body, and a filter component 120 connected to the raw water tank 110. The raw water tank 110 can be connected to an external water source and can store raw water. The raw water can be tap water, groundwater, mountain water, etc. The filter component 120 is used to filter the raw water and produce drinkable pure water. A raw water flow channel 130 is provided between the raw water tank 110 and the water inlet end of the filter component 120. The raw water flow channel 130 can guide the raw water in the raw water tank 110 to the filter component 120 for filtration. A pure water flow channel 140 is provided between the pure water output end of the filter component 120 and the cold water tank 300. The pure water flow channel 140 can guide the drinkable pure water formed by filtering the raw water by the filter component 120 to In the cold water tank 300, the ice-making mechanism 200 includes a refrigerator 210 located on the upper side of the ice crushing mechanism 400 and an ice-making assembly 220 connected to the refrigerator 210. The ice-making assembly 220 is used for making ice. The refrigerator 210 is provided with an ice storage chamber 211 that can accommodate ice and is connected to the ice crushing mechanism 400. The first cold water flow channel 600 is connected between the ice-making assembly 220 and the cold water tank 300 to divert the water in the cold water tank 300 to the ice-making assembly 220 for secondary ice making. The second cold water flow channel 700 is connected between the raw water tank 110 and the cold water tank 300 to divert the water in the cold water tank 300 to the raw water tank 110 so that the water can be filtered and purified for secondary use by the filter assembly 120.

[0036] When the ice purifier is running, raw water is input into the filter assembly 120 through the raw water flow channel 130, and the raw water is filtered by the filter assembly 120 to produce drinkable pure water. Then, the pure water can flow into the cold water tank 300 through the pure water flow channel 140, and the water in the cold water tank 300 can be guided to the ice-making assembly 220 through the first cold water flow channel 600 for ice making. The ice cubes made by the pure water in the ice-making assembly 220 can enter the ice crushing mechanism 400 through the ice storage chamber 211, and are further crushed by the ice crushing mechanism 400 to form crushed ice and exported to the user. In addition, when the water in the cold water tank 300 has been left for too long, the water in the cold water tank 300 can be diverted to the raw water tank 110 through the second cold water flow channel 700 and filtered twice by the filter assembly 120 to improve the water quality. The pure water formed by the secondary filtration of the filter assembly 120 enters the cold water tank 300 again through the pure water flow channel 140, thereby realizing water circulation in the ice purifier, thereby improving water utilization, reducing water resource waste, and improving ice quality. The melted ice water generated when the ice crushing mechanism 400 is crushing ice can flow back to the cold water tank 300 along the cold water return flow channel 500, and the melted ice water in the ice crushing mechanism 400 can be cleaned in time, thereby preventing bacteria from growing inside the ice purifier, thereby improving the water quality and ice quality in the ice purifier. It should be noted that the ice storage chamber 211 can be connected to the outside, and the refrigerator 210 is connected to the ice crushing mechanism 400 through the ice storage chamber 211, so that the ice cubes in the ice storage chamber 211 can enter the ice crushing mechanism 400, and the melted water of the ice cubes in the ice storage chamber 211 can also enter the ice crushing mechanism 400. Therefore, the water flowing from the ice crushing mechanism 400 to the cold water return channel 500 also includes the melted water of the ice cubes in the ice storage chamber 211.

[0037] Optionally, corresponding valves and / or pumps may be provided in the raw water channel 130, the pure water channel 140, the first cold water channel 600, and the second cold water channel 700 to facilitate water delivery. For example, a water pump may be provided in each of the raw water channel 130, the first cold water channel 600, and the second cold water channel 700, and a valve capable of controlling the flow of the channel may be provided in the pure water channel 140. The above configuration is only one implementation, and this embodiment does not limit the specific configuration of the valves or pumps in each channel.

[0038] Specifically, such as Figure 2As shown in FIG. 10 , the ice crushing mechanism 400 includes a main shell 410 provided on the lower side of the ice making mechanism 200, and the ice crushing assembly 420 provided in the main shell 410. The main shell 410 is provided with an ice crushing chamber 411 and an ice discharge chamber 412 that are connected to each other, and a partition 413 located between the ice crushing chamber 411 and the ice discharge chamber 412. The partition 413 is provided with a first drain port 4131 that is connected to the ice crushing chamber 411 and the ice discharge chamber 412. A drainage channel that is connected to the cold water return channel 500 is formed between the ice crushing chamber 411, the first drain port 4131 and the ice discharge chamber 412. In this embodiment, the ice crushing chamber 411 is arranged near the top of the main shell 410 and is open upward. When installed, the ice making refrigerator 210 is placed on the upper side of the main shell 410. At least a portion of the ice making refrigerator 210 can extend into the ice crushing chamber 411, and the ice storage chamber 211 is connected to the ice crushing chamber 411 so that the ice cubes in the ice storage chamber 211 can enter the ice crushing chamber 411. The ice discharge chamber 412 is arranged at the lower part of the ice crushing chamber 411. The ice crushing chamber 411 and the ice discharge chamber 412 are separated by the partition 413. The ice crushing chamber 411 can accommodate ice cubes and ice cubes. Melted water. By providing the first drain port 4131 in the partition 413, melted water from the ice in the ice crushing chamber 411 can flow along the first drain port 4131 into the ice discharge chamber 412. The drainage channel is formed by the ice crushing chamber 411, the first drain port 4131, and the ice discharge chamber 412. Therefore, the melted water in the ice crushing chamber 411 is located in the drainage channel and flows sequentially through the first drain port 4131 and the ice discharge chamber 412 into the cold water return channel 500. The cold water return channel 500 then directs the melted water into the cold water tank 300 for secondary use. It should be noted that the drainage channel can be formed by the inner walls of the ice crushing chamber 411, the first drain port 4131, and the ice discharge chamber 412, that is, it can be formed by the inner wall of the main bracket. In addition, optionally, a water pipe may be provided at the lower portion of the first drain port 4131 , and the water pipe may extend into the ice discharge chamber 412 to facilitate drainage; the water pipe and the partition 413 may be an integrated structure or a split structure.

[0039] More specifically, Figure 2As shown in FIG11 , the main shell 410 is provided with an opening 4111 connected to the ice crushing chamber 411, and the ice crushing mechanism 400 also includes an ice discharge chute 430 provided at the opening 4111 and connected to the ice crushing chamber 411, and an ice outlet 431 provided at the end of the ice discharge chute 430.

In this embodiment, the main bracket can be divided into an upper part corresponding to the ice crushing chamber 411 and a lower part corresponding to the ice discharge chamber 412. The partition 413 is arranged between the upper and lower parts of the main bracket. The lower part of the main bracket is provided with an opening 4111 communicating with the ice crushing chamber 411, and the ice discharge chute 430 is provided at the opening 4111. The ice crushing chamber 411 is communicated with the ice discharge chute 430 through the opening 4111, so that the ice in the ice discharge chamber 412 can slide along the ice discharge chute 430 to the outside of the ice crushing mechanism 400, so as to facilitate the user to receive the ice; when the ice in the ice discharge chamber 412 slides out along the ice discharge chute 430, the friction between the ice and the ice discharge chute 430 will accelerate the melting speed of the ice, so that the ice discharge chute 430 Water stains are easy to remain. As the output of ice cubes increases, water stains in the ice discharging chute 430 gradually accumulate and form water flows, and the water flows will also flow out to the outside along the ice discharging chute 430, causing water leakage. In order to prevent the ice discharging chute 430 from leaking, a second drain port 432 connected to the cold water return flow channel 500 is provided in the ice discharging chute 430 along the ice discharging direction of the ice discharging chute 430, and the second drain port 432 is located at the front side of the ice discharging port 431, so that water flows directly into the cold water return flow channel 500 through the second drain port 432 and flows into the cold water tank 300 along the cold water return flow channel 500, so as to prevent the melted water of ice cubes from being output to the user along the ice discharging chute 430, and further realize the recovery of the melted water of ice cubes in the ice crushing mechanism 400, thereby improving the utilization rate of water and reducing the waste of water resources. In this embodiment, the drainage channel can also be formed by the ice crushing chamber 411, the first drain outlet 4131, the ice discharge chamber 412 and the second drain outlet 432, that is, part of the inner wall of the ice discharge chute 430 is also one of the components of the drainage channel. Preferably, a connecting pipe connected to the second drain outlet 432 can also be provided at the lower part of the ice discharge chute 430, which is conducive to connecting the second drain outlet 432 and the cold water tank 300 through a pipeline and forming the cold water return channel 500. Optionally, the connecting pipe and the ice discharge chute 430 can be an integrated structure or a split structure.

[0040] On the other hand, Figure 2As shown in FIG. 11 , the ice crushing assembly 420 includes an ice guide 421 rotatably arranged in the ice crushing chamber 411, a driving device 422 connected to the ice guide 421, and an ice crushing knife 423 arranged in the ice crushing chamber 411. The ice guide 421 is provided with a connecting portion 4211 connected to the driving device 422, an ice guide portion 4212 connected to the connecting portion 4211 and arranged in the ice crushing chamber 411, and the ice guide portion 4212 is opposite to the inner wall of the ice crushing chamber 411 and is shaped The ice guide 421 is driven by the driving device 422 to rotate in the ice crushing chamber 411, and the ice guide portion 4212 is driven to rotate relative to the blade 4231 of the ice crushing knife 423. Specifically, in this embodiment, the ice guide 421 is connected to the driving device 422 through the connecting portion 4211, the connecting portion 4211 can be set as a connecting shaft, and a mounting hole adapted to the connecting shaft can be set in the axial direction of the main bracket. During installation, the connecting portion 4211 can pass through the mounting hole to connect to the driving device 422, and the driving device 422 is placed on the lower side of the main bracket; when the ice crushing mechanism 400 is in operation, the ice cubes in the ice making bin 210 fall into the ice crushing chamber 411, and the ice guide 421 is driven by the driving device 422 to crush the ice. The ice guide 4212 rotates in the ice crushing chamber 411 and drives the ice guide 4212 to rotate in the ice crushing chamber 411 relative to the blade 4231 of the ice crushing knife 423. At this time, the ice cubes in the ice crushing chamber 411 are pushed by the ice guide 4212 to move toward the blade 4231 in the ice crushing chamber 411, and the ice cubes are crushed by the blade 4231 to form crushed ice. The crushed ice can fall into the ice discharge chamber 412 through the ice discharge port 4133 and slide out to the outside along the ice discharge chute 430. It should be noted that the ice crushing knife 423 in this embodiment can be stationary, and ice crushing is achieved by the ice cubes moving toward the ice crushing knife 423. In addition, optionally, the driving device 422 can adopt a common driving motor, which is easy to implement, and the ice guide 421 can be directly connected to the driving motor through the connecting portion 4211, so as to improve the transmission efficiency of the driving device 422 to the ice guide 421; the above is one of the implementation methods of the driving device 422, and this embodiment does not limit the specific connection between the ice guide 421 and the driving device 422; in addition, the driving device 422 can also be connected to the ice guide 421 through a transmission device.

[0041] Optionally, in other embodiments, the ice discharge port 4133 is arranged close to the opening 4111 to reduce the distance between the falling position of the crushed ice in the ice discharge chamber 412 and the ice discharge chute 430, so that the crushed ice can enter the ice discharge chute 430 faster and slide out to the outside, thereby improving the ice discharge efficiency of the ice crushing mechanism 400.

[0042] In other embodiments, as preferred embodiments of the present invention but not limited thereto, Figure 9 and Figure 11 As shown, the ice chute 430 is further provided with a water retaining portion 433 located between the second drain outlet 432 and the ice outlet 431. The water retaining portion 433 extends upward along the height of the ice chute 430. The water retaining portion 433 restricts the meltwater in the ice chute 430 from flowing out through the ice outlet 431 to the outside, further preventing water leakage at the ice outlet 431. This increases the success rate of meltwater in the ice chute 430 flowing through the second drain outlet 432 into the cold water return channel 500, thereby improving the efficiency of meltwater recovery. It should be noted that the water retaining portion 433 only needs to extend upward along the height of the ice chute 430 to a height that can block the water flow in the ice chute 430. Optionally, the water retaining portion 433 and the ice chute 430 are integral structures.

[0044] In addition, optional, such as Figure 11As shown, the ice outlet chute 430 is further provided with a first ice guide wall 435 and a second ice guide wall 436 located on both sides of the inclined bottom wall 434 and arranged opposite to each other. The distance between the first ice guide wall 435 and the second ice guide wall 436 gradually decreases along the ice outlet direction of the ice outlet chute 430. In this embodiment, the first ice guide wall 435 and the second ice guide wall 436 extend upward along both sides of the inclined bottom wall 434 respectively, and the ice discharging chute 430 is connected to the main shell 410 through the first ice guide wall 435 and the second ice guide wall 436, and the connection between the first ice guide wall 435 and the second ice guide wall 436 and the main shell 410 is the opening 4111; by setting the distance between the first ice guide wall 435 and the second ice guide wall 436 to gradually decrease, the ice cubes in the ice discharging chute 430 can be gathered together as the distance between the first ice guide wall 435 and the second ice guide wall 436 is narrowed when the ice is discharged. When the user receives the ice, the ice cubes can be more evenly distributed in the receiving area, avoiding the situation where too much or too little ice cubes are locally accumulated when the ice outlet 431 is discharged, which is more conducive to the user's ice receiving experience when making cold drinks or processing food. In addition, because the inclined bottom wall 434 extends obliquely from the opening 4111 toward the ice outlet 431, that is, the height of the ice outlet chute 430 continuously increases along the extension direction of the inclined bottom wall 434, ice cubes can obtain greater downward momentum under the action of gravity, thereby sliding out more smoothly along the inclined bottom wall 434, which helps to prevent ice cubes from accumulating and clogging in the ice outlet chute 430. It should be noted that the ice outlet direction of the ice outlet chute 430 can be from the direction from the opening 4111 toward the ice outlet 431.

[0045] In some other embodiments, the water retaining portion 433 is disposed at the end of the inclined bottom wall 434 , and the second drain port 432 is disposed between the water retaining portion 433 and the inclined bottom wall 434 .

The first drain port 4131 is disposed near the bottom of the water guide wall 4132. In this embodiment, the water guide wall 4132 can be configured as a funnel-shaped wall. The water guide wall 4132 can form the inner wall of the ice crushing chamber 411 and is part of the drainage channel. With this configuration, the water guide wall 4132 extends downwardly along the height direction of the main housing 410, thereby increasing the speed at which ice cubes and meltwater in the ice crushing chamber 411 slide along the water guide wall 4132 under the action of gravity, thereby improving the drainage and ice discharge efficiency of the ice crushing mechanism 400.

[0047] In other embodiments, as preferred embodiments of the present invention but not limited thereto, Figure 12 and Figure 13 As shown, the main housing 410 includes a first housing 401 and a second housing 402 connected vertically.

At least a portion of the first housing 401 can extend into the ice discharge chamber 412, and the partition 413 is provided in the portion of the first housing 401 that extends into the ice discharge chamber 412. In this embodiment, the first housing 401 and the second housing 402 are arranged vertically and detachably connected inside the ice purifier. The top of the first housing 401 is upwardly open to connect the ice crushing chamber 411 to the outside, and the top of the second housing 402 is upwardly open to connect the ice discharge chamber 412 to the outside. The centers of the first housing 401 and the second housing 402 are provided with corresponding first and second through holes along the axial direction. The first and second through holes are adapted to the connection portion 4211 of the ice guide 421. When installed, at least a portion of the ice maker 210 can extend into the ice crushing chamber 411. The ice guide The ice guide portion 4212 of 421 is placed in the ice crushing chamber 411, and the connecting portion 4211 of the ice guide 421 passes through the first through hole and the second through hole in sequence to be connected to the driving device 422. The driving device 422 is placed on the lower side of the second shell 402. At least a portion of the first shell 401 can extend into the ice discharge chamber 412, and the first shell 401 separates the ice crushing chamber 411 and the ice discharge chamber 412 through the partition 413. The main shell 410 is formed by the detachable connection between the first shell 401 and the second shell 402, so as to facilitate the maintenance and replacement of the ice crushing assembly 420.

[0048] In other embodiments, the ice discharge chute 430 is provided on one side of the second shell 402 . Specifically, the opening 4111 is provided in the second shell 402 , and the ice discharge chute 430 is connected to the opening 4111 .
