[0023] Figure 4 This is a schematic diagram of the limiting device in this utility model;

[0024] Figure 5 This is a schematic diagram of the structure of the bullet-shaped ice-making head connected to the evaporator in this utility model; Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1 to 5 The ice-making structure of a portable refrigerator shown includes a cabinet 1, an evaporator 2, and a water storage tray 3 rotatably connected to the cabinet 1. The evaporator 2 is connected to a bullet-shaped ice-making head 21 that extends into the water storage tray 3. The cabinet 1 is also provided with a drive 4 that can drive the water storage tray 3 to flip and pour out the ice and water in the tray, and a collection bucket 5 that can collect the ice and water poured out by the water storage tray 3. The collection bucket 5 contains a basket 6 that can drain the ice.

[0027] In this application, the bullet-shaped ice-making head 21 is designed to utilize the cooling capacity provided by the evaporator 2 more effectively because its shape allows for better contact and freezing of the water in the water storage pan 3, thereby accelerating the ice-making process. The automatic flipping function of the water storage pan 3, achieved by the driver 4, allows the ice and remaining water to be automatically poured out after ice making, reducing the need for manual intervention and improving the user experience. The collection bucket 5 not only collects the made ice but also recycles unfrozen water, which can be reused in the ice-making process, achieving effective recycling of water resources and promoting environmental protection and energy conservation. The basket 6 allows the ice to be easily removed after it has been drained, and users can directly pick up the basket 6 to get the ice, reducing the amount of mixed water and making it more convenient to use.

[0028] Specifically, the ice-making structure also includes a controller installed on the refrigerator or cabinet 1 and capable of controlling the operation of the ice-making structure. The controller is electrically connected to the driver 4, the evaporator 2, and the limiting device 8.

[0029] Furthermore, the housing 1 is equipped with a guide ramp 11 that allows ice and water poured from the water storage tray 3 to flow into the collection bucket 5. An opening 12 is provided between the collection bucket 5 and the water storage tray 3 to provide space for removing the basket 6. The guide ramp 11 ensures that the ice and water poured from the water storage tray 3 flow smoothly into the collection bucket 5, reducing the possibility of ice getting stuck or water stagnating. The opening 12 provides sufficient space for removing the basket 6, allowing the user to easily retrieve the drained ice.

[0030] In one embodiment, a support structure 7 is provided between the basket 6 and the collection bucket 5 to support the basket 6, thereby creating a drainage space between the basket 6 and the inner bottom of the collection bucket 5. The support structure 7 ensures that the basket 6 does not directly contact the bottom of the collection bucket 5, thus forming a drainage space between them. This allows the ice to drain thoroughly, preventing it from melting or sticking together due to water accumulation, ensuring the quality and effectiveness of the ice. The existence of the drainage space helps to separate excess water from the ice and retain it at the bottom of the collection bucket 5. Raising the basket 6 by the support structure 7 reduces the chance of the ice coming into contact with dirt or impurities that may be present at the bottom of the collection bucket 5, improving hygiene standards, especially important when used in outdoor environments. Once the basket 6 is stably supported, the user can more easily remove it from the collection bucket 5. The bottom of the basket 6 has a drain hole 61 for drainage.

[0031] Specifically, the support structure 7 includes support feet 71 disposed on the inner side wall of the collection bucket 5. The support structure 7 also includes slots 72 disposed on the outer side wall of the basket 6 for the support feet 71 to be inserted.

[0032] In one embodiment, a limiting device 8 is provided between the water storage tray 3 and the housing 1 to limit the rotation angle of the water storage tray 3. The water storage tray 3 is rotatably connected to the housing 1 via a rotating shaft, and a protrusion 81 that can follow its rotation is connected to the rotating shaft. The limiting device 8 includes two jog switches 82 that can be triggered by the protrusion 81, and the jog switches 82 are located on the rotation path of the protrusion 81.

[0033] The limiting device 8 ensures that the water storage tray 3 can only rotate within a predetermined angle range, preventing excessive or insufficient tilting. This ensures that each pouring of ice and water is completed accurately, improving operational reliability. The jog switch 82 can automatically detect and respond to changes in the position of the water storage tray 3. When the protrusion 81 triggers the jog switch 82, it can send a signal to the controller, thereby automating the tilting process of the water storage tray 3.

[0034] In one embodiment, the bottom of the collection bucket 5 is provided with a drain pipe 9 for draining water. A plug or switch can be connected to the drain pipe 9 to control its opening and closing.

[0035] In one embodiment, water can be pumped back to the water storage pan 3 for ice making via water pipes and pumps, thereby improving water utilization.

[0036] In one embodiment, the housing 1 is further provided with a first protective shell 13 for shielding the driver 4 and a second protective shell 14 for shielding and installing the limiting device 8. This provides physical protection to prevent damage from external impacts or misoperation, ensuring its long-term stable operation. It also limits human contact and prevents mechanical injury.
