[0029] The main body 2 includes a storage cavity 1. Cavity 1 is open relative to the front of the main body 2 and may include several internal panels and hooks. A door panel 3 is rotatably connected to the main body 2 and can be movably sealed within cavity 1, providing a sealed and protective seal. An ice-making device 4 is located within the main body 2 and may include an evaporator, a compressor, a condenser, an ice outlet 6, a water inlet, and other components. It cools purified water into ice cubes, thereby producing ice cubes. An ice box 5 is located within the main body 2, corresponding to the ice outlet 6 of the ice-making device 4, and serves to receive ice cubes. The ice box 5 communicates with the interior of cavity 1 and may include an ice dropout 24 at the top of cavity 1, which communicates with the ice box 5. A switch mechanism is located between the ice box 5 and cavity 1 and can be operated to control the opening and closing of ice dropout 24. This allows ice cubes within the ice box 5 to enter the cavity 1 through ice dropout 24, thereby controlling ice discharge.

[0030] The ice outlet 6 is located on the front side of the ice making device 4 and can be tilted downward. It is connected to the inside of the ice box 5. After the ice making device 4 completes ice making, the ice cubes fall from the ice outlet 6 into the inside of the ice box 5, serving as ice storage. The water inlet is located on the rear side of the ice making device 4 and is connected to the water supply system to play a water injection role, wherein: the water storage tank 7 is located on the top of the fuselage 2, is detachably connected to the fuselage 2, and is connected to the water inlet, providing a water injection method for the water storage tank 7, which is suitable for use in ordinary scenes.

Purified water can be added to the water storage tank 7, bottled water 10 can be plugged into the insertion port 8, or a water purifier 11 can be connected to the external interface 9 to meet the needs of different scenarios. When ice making is required, water is supplied through the water storage tank 7, the insertion port 8, and the external interface 9.

The opening of the water tank cavity 12 faces upward, allowing the water tank 7 to be installed downward. The drain hole 13 is located at the bottom of the water tank cavity 12, extends vertically downward, and is connected to the water inlet. The drain pipe 14 is located at the bottom of the water tank 7, extends vertically downward, and matches the shape and position of the drain hole 13. When the water tank 7 is downwardly installed in the water tank cavity 12, the drain pipe 14 is plugged into the drain hole 13, and the bottom of the water tank 7 abuts the bottom of the water tank cavity 12. Pure water enters the drain hole 13 through the drain pipe 14, thereby connecting the water tank 7 with the water inlet.

When the water storage tank 7 is embedded downward in the water tank cavity 12, the drain pipe 14 is plugged into the drain hole 13, and the flow-limiting column 15 extends into the drain pipe 14 until the bottom of the water storage tank 7 abuts the bottom of the water tank cavity 12. The top of the flow-limiting column 15 is telescopically connected to the flow-limiting ball 16, and the flow-limiting column 15 squeezes the flow-limiting ball 16 upward, and the flow-limiting ball 16 is separated from the top of the drain pipe 14. Pure water enters the drain hole 13 through the drain pipe 14, achieving a movable sealing effect.

[0036] In this embodiment, preferably, a flow limiting cover 17 for accommodating a flow limiting ball 16 is provided above the drain pipe 14, a return spring 18 is connected between the flow limiting ball 16 and the flow limiting cover 17, and a plurality of water flow grooves 19 are provided on the side wall of the flow limiting cover 17.

[0037] The flow limiting cover 17 is located above the drain pipe 14. A space is provided inside to accommodate the flow limiting ball 16. It is a cylindrical structure with a closed top and an open bottom. The bottom end of the flow limiting cover 17 is connected to the bottom of the water tank 7. The flow limiting ball 16 is placed inside the flow limiting cover 17 and is connected to the flow limiting cover 17 by sliding up and down. The reset spring 18 is located between the flow limiting ball 16 and the flow limiting cover 17.

One side of the water flow trough 19 is connected to the inside of the water tank 7, and the other side of the water flow trough 19 is connected to the inside of the flow limiting cover 17. Under normal conditions, the reset spring 18 is in a relaxed state, pushing the flow limiting ball 16 downward. The flow limiting ball 16 abuts against the top of the drain pipe 14, sealing the drain pipe 14, and preventing pure water from entering the drain pipe 14. When the bottom of the water tank 7 abuts the bottom of the water tank cavity 12, the flow limiting column 15 squeezes the flow limiting ball 16 upward, the return spring 18 is in a compressed state, the flow limiting ball 16 detaches from the top of the drain pipe 14, and the pure water enters the drain hole 13 through the drain pipe 14.

[0038] In this embodiment, as a preference, an electromagnetically controllable control valve is provided between the water supply system and the water inlet, the water supply end of the control valve is respectively connected to the water tank 7, the plug-in port 8, and the external interface 9, the water delivery end of the control valve is connected to the water inlet, and the control valve is connected to a controller.

[0039] The control valve is located inside the body 2, between the water supply system and the water inlet. It is connected to the controller and has electromagnetic control capabilities. The control valve has a four-way joint structure, including three water supply ends and one water delivery end. The water supply ends are respectively connected to the water storage tank 7, the plug-in port 8, and the external interface 9, while the water delivery end is connected to the water inlet. A water inlet pump can be connected between the water delivery end and the water inlet. Under the action of the water inlet pump, pure water is drawn from the water storage tank 7, the plug-in port 8, and the external interface 9, increasing the water supply pressure. Under the control of the controller, the control valve realizes electromagnetic switching, opening or closing each water supply end, allowing users to select the water supply method as needed.

The flow sensor is located between the water delivery end and the water inlet, and provides feedback on whether pure water is flowing in. The water level sensor, contact sensor, and flow sensor are respectively connected to the controller, and the controller is connected to the control valve.

The return channel 22 is located at the end of the guide groove 21 and is connected to the interior of the water storage tank 7. A return pump can be connected between the return channel 22 and the water storage tank 7. The return pump draws ice melt water from the return channel 22 to increase the water supply pressure. After the ice-making device 4 completes ice making, the ice cubes fall from the ice outlet 6 into the ice box 5 and move downward along the guide surface 20 to the bottom of the ice box 5. While the ice cubes are stored in the ice box 5, they melt and produce a certain amount of ice melt water. This ice melt water flows along the guide groove 21 and converges in the return channel 22. Through the return channel 22, it enters the water storage tank 7 and is recycled.

[0044] In this embodiment, as a preference, the switch mechanism includes an ice pushing plate provided at the bottom of the ice box 5, an ice pushing groove 23 connected to the bottom of the ice box 5, and an ice drop port 24 connected to the interior of the cavity 1.

[0045] The ice push plate is located at the bottom of the ice box 5 and is arranged to extend horizontally. It can be a groove structure arranged horizontally at the bottom of the ice box 5. The ice push plate is embedded in the bottom of the ice box 5 and is connected to the bottom of the ice box 5 in a horizontal sliding manner. The ice push groove 23 is located inside the fuselage 2 and is connected to the bottom of the ice box 5. The ice push groove 23 and the bottom of the ice box 5 can match each other in shape and position, and the two are connected to each other. The ice push plate is slidably connected to the ice push groove 23. The ice push plate can slide from the bottom of the ice box 5 to the inside of the ice push groove 23.

When ice needs to be taken, the cup is placed inside the cavity 1, corresponding to the bottom of the ice drop port 24. The ice pushing plate slides along the bottom of the ice box 5, pushing the ice cubes at the bottom of the ice box 5 into the ice pushing groove 23. The ice cubes enter the ice drop port 24 from the ice pushing groove 23 and fall into the cup from the ice drop port 24, realizing the ice taking function.

[0046] In this embodiment, as a preference, the ice pushing plate includes an ice holding hole 25 provided in the middle, and guide blocks 26 provided at both ends.

The ice drop port 24 is matched with the ice hole 25. After the ice-making device 4 completes ice making, the ice cubes fall into the interior of the ice box 5 from the ice outlet 6 and slide into the ice hole 25. The ice hole 25 can limit the number of ice cubes that can be taken out at one time. When ice is needed, the ice pusher slides along the bottom of the ice box 5, driving the ice cubes inside the ice hole 25 into the ice pusher groove 23 until the ice drop port 24 is aligned with the ice hole 25. The ice cubes then enter the ice drop port 24 from the ice pusher groove 23 and fall into the cup. In addition, after the ice pusher enters the ice pusher groove 23, the guide block 26 seals the bottom space of the ice box 5 to prevent ice cubes from getting stuck at the bottom of the ice box 5 and affecting the return of the ice pusher.
