[0031] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] like Figures 1 to 4 As shown, the first embodiment of the present invention provides an ice making machine, comprising:

[0033] The housing 100 includes an ice-making mold 102 therein, and a water outlet 104 is provided on the ice-making mold 102;

[0034] A water supply tank 106 is provided in the housing 100;

[0035] A water collection box 108 is disposed on the housing 100 and is in fluid communication with the water outlet 104 and the water supply tank 106;

[0036] The heating component is disposed in the housing 100 and is used to heat the water flowing into the water supply tank 106 from the water collecting box 108 .

[0037] According to the ice maker provided by the embodiment of the first aspect of the present invention, the fluid connection design between the water collecting box 108 and the water supply tank 106 realizes the recycling of water, which not only reduces the waste of water resources, but also reduces the operating cost of the ice maker. The setting of the heating component allows the water to be preheated when necessary, thereby ensuring that the water temperature is always kept within an appropriate range, which helps to optimize the ice making process, improve ice making efficiency, and reduce the increase in energy consumption caused by too low water temperature. The above-mentioned various components are integrated in the shell 100, making the structure of the ice maker more compact, easy to install and maintain. At the same time, this design also helps to reduce noise and vibration, and improve the user experience. Thus, the ice maker achieves efficient recycling of water and optimization of ice making efficiency through the innovative fluid connection design and the application of the heating component, while maintaining the compactness of the structure and the ease of maintenance.

[0038] Please continue to see Figures 1 to 4 The first embodiment of the present invention is to provide an ice maker with efficient ice making and water recycling functions. The ice maker mainly consists of the following key components:

[0039] The housing 100 serves as the main structure of the ice maker. An ice mold 102 is located within the housing 100 for producing ice cubes during the ice-making process. A water outlet 104 is provided on the ice mold 102. This allows the water in the ice mold 102 to overflow after the ice mold 102 is fully filled, ensuring that the water in the ice mold 102 completely fills the ice mold 102, thereby facilitating the production of complete ice cubes without air holes.

[0040] The water supply tank 106 is provided in the housing 100 for storing and supplying water required for ice making. The water tank is connected to the ice making mold 102 via a water inlet pipe 120 to supply water to the ice making mold 102.

[0041] A water collection box 108 is also disposed within the housing 100, positioned above the ice mold 102 and corresponding to the water outlet 104. The water collection box 108 is used to collect water overflowing from the water outlet 104. The water collection box 108 is connected to the water supply tank 106 via a fluid channel, ensuring that the collected water can flow back into the water supply tank 106.

[0042] The heating assembly, located within housing 100, heats the water flowing from water collection box 108 into water supply tank 106. This heating assembly is designed to elevate the water temperature so that it can be preheated when necessary (e.g., when the water temperature is too low to effectively make ice), thereby optimizing the ice-making process. This prevents the water from freezing and effectively prevents the ice maker from running dry.

[0043] like Figure 3As shown, according to one embodiment of the present invention, in the vertical direction, the water collecting box 108 is arranged above the water supply box 106, the water collecting box 108 is fluidically connected to the water supply box 106 through the guide groove 110, and the heating component is correspondingly arranged to the guide groove 110.

[0044] In one embodiment of the present invention, in the vertical direction, the water collection box 108 is arranged above the water supply tank 106. Such a layout design facilitates the water collected in the water collection box 108 to flow naturally to the water supply tank 106 by gravity without the need for additional power equipment.

[0045] The water collection box 108 and the water supply tank 106 are fluidically connected via a flow channel 110. As a fluid transmission structure, the flow channel 110 ensures that the water in the water collection box 108 flows smoothly and orderly into the water supply tank 106. This design not only improves water transmission efficiency but also avoids water waste and splashing.

[0046] The heating assembly is positioned in correspondence with the guide groove 110, which means that the heating assembly can heat the water flowing through the guide groove 110, thereby meeting the water temperature requirements in specific application scenarios. The location of the heating assembly ensures that the heat can directly act on the water flow, improving heating efficiency.

[0047] By placing the water collection box 108 above the water supply tank 106 and utilizing gravity to facilitate the natural flow of water, this technical solution reduces water waste during transport and improves water utilization efficiency. By eliminating the need for additional power equipment to transport water, this technical solution reduces energy consumption while also enhancing the stability of the entire water supply and heating system. The corresponding arrangement of the heating assembly and the diversion trough 110 allows heat to be directly applied to the water flow, thereby improving heating efficiency, shortening heating time, and reducing energy consumption.

[0048] like Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, an air supply member 112 is further installed on the housing 100 , and the air outlet direction of the air supply member 112 is toward the water collecting box 108 .

[0049] In one embodiment of the present invention, an air supply member 112 is installed on the housing 100 of the ice maker. This design is intended to further optimize the performance and efficiency of the ice maker.

[0050] The air supply member 112 can be a fan or a blower, and is installed at an appropriate position of the housing 100 to ensure that the air it blows directly toward the water collection box 108. This design can utilize the airflow generated by the air supply member 112 to accelerate the circulation of the airflow, so that the heat generated by the heating component can be evenly distributed on the surface of the water collection box 108, thereby achieving uniform heating of the water in the water collection box 108.

[0051] In some other embodiments, the air supply member 112 can also be used to blow air to dry the water collection box 108, especially when there is a lot of water in the water collection box 108 or when quick drying is required. By accelerating the evaporation of water, the air supply member 112 helps reduce the amount of water accumulated in the water collection box 108, thereby keeping the water collection box 108 clean and dry.

[0052] The airflow generated by the air supply element 112 circulates and distributes the heat generated by the heating assembly, evenly heating the water in the water collection box 108 and facilitating a uniform temperature increase. When the water in the water collection box 108 flows back into the water tank, freezing of the water in the water collection box 108 and the water tank can be prevented. By uniformly raising the temperature of the water in the water collection box 108 and the water tank, dry-boiling of the ice maker can be avoided.

[0053] like Figure 2 As shown, according to one embodiment of the present invention, it also includes a temperature detection component 114, which is electrically connected to the heating component. The temperature detection component 114 is used to detect the water temperature of at least one of the water collection box 108 and the water supply tank 106, and the heating component is suitable for starting and stopping based on the detection result of the temperature detection component 114.

[0054] In one embodiment of the present invention, a temperature detection element 114 is added to the ice maker to provide more intelligent temperature control, thereby ensuring that the ice maker can maintain efficient and stable operation under various working conditions.

[0055] Temperature sensor 114 is electrically connected to the heating assembly, forming a closed-loop temperature control system. Temperature sensor 114 is configured to detect the water temperature in at least one of the water collection box 108 and the water supply tank 106. This means that temperature sensor 114 can monitor the water temperature in key areas in real time, ensuring that the water temperature remains within an appropriate range.

[0056] The heating component is controlled to start and stop based on the detection results of the temperature sensor 114. When the temperature sensor 114 detects that the water temperature is lower than the preset value, the heating component automatically starts to heat the water. Once the water temperature reaches or exceeds the preset value, the heating component stops, avoiding energy waste and excessive wear and tear on the equipment.

[0057] By incorporating temperature sensor 114, the ice maker can monitor water temperature in real time and adjust it based on actual needs. This significantly improves temperature control accuracy, ensuring the stability and reliability of the ice-making process. The heating component's start and stop control is based on the detection results of temperature sensor 114, avoiding unnecessary energy waste. When the water temperature is appropriate, the heating component stops operating, thereby reducing the device's energy consumption. Through precise temperature control, the ice maker can avoid damage caused by excessively high or low water temperatures. This helps extend the device's service life and reduces the frequency of repairs and component replacements.

[0058] like Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, a water supply component 116 is further provided in the shell 100, a water inlet 118 is opened on the ice making mold 102, the water supply component 116 is fluidically connected to the water inlet 118 through a water inlet pipe 120, and the water supply component 116 is fluidically connected to the water supply tank 106 through a return pipe 122.

[0059] In one embodiment of the present invention, a water supply component 116 and its related fluid communication structure are newly added to improve the automation level and water supply efficiency of the ice maker, thereby ensuring the stability and reliability of the ice making process.

[0060] A water supply member 116 is disposed within the housing 100 and is used to supply water required for ice making to the ice mold 102. To achieve this, the water supply member 116 is in fluid communication with a water inlet 118 provided in the ice mold 102 via a water inlet pipe 120. Thus, when the water supply member 116 is activated, it can deliver water through the water inlet pipe 120 to the water inlet 118 of the ice mold 102, thereby filling the ice mold 102.

[0061] At the same time, water supply element 116 is also in fluid communication with water supply tank 106 via a return pipe 122. This means that after water supply element 116 supplies water to ice-making mold 102, excess water or water not used for ice making can flow back into water supply tank 106 via return pipe 122. This design not only recycles water but also avoids water waste. More importantly, the provision of return pipe 122 prevents pressure buildup and overload in water supply element 116 due to freezing of the water tank piping.

[0062] Thus, through the water supply component 116 and its associated fluid communication structure, the ice maker can more quickly and accurately provide the required amount of water to the ice mold 102, helping to improve the ice maker's water supply efficiency and thus speed up ice making. The design of the return pipe 122 allows excess water to flow back to the water supply tank 106, achieving water recycling. This not only reduces water waste and lowers the operating costs of the ice maker, but also prevents pressure buildup and overload in the water supply component 116, facilitating the long-term safe use of the ice maker.

[0063] like Figure 3 As shown, according to one embodiment of the present invention, the water outlet 104 is opened at the top of the ice-making mold 102 , and in the vertical direction, the height of the water inlet 118 is lower than the height of the water outlet 104 .

[0064] In one embodiment of the present invention, the water outlet 104 is located at the top of the ice mold 102, while the water inlet 118 is vertically positioned lower than the water outlet 104. This design is intended to improve ice making efficiency and ice quality while ensuring a smooth ice making process.

[0065] In this embodiment, the water outlet 104 is set at the top of the ice-making mold 102. In this way, when water gradually fills the ice-making mold 102, excess water can flow out through the water outlet 104 at the top in the form of overflow, which can ensure that the ice-making mold 102 is completely filled with water, and is also conducive to the complete formation of ice cubes, avoiding the formation of air holes in the ice cubes.

[0066] At the same time, the height of the water inlet 118 is set to be lower than the height of the water outlet 104. This design ensures that water can be evenly distributed in the ice making mold 102 when entering the ice making mold 102, thereby helping to form ice cubes of regular shape and uniform size.

[0067] The water outlet 104 is located at the top of the ice mold 102, facilitating water filling and promoting ice formation. The design of the water inlet 118 being lower than the water outlet 104 ensures that water fills the ice mold 102 evenly and quickly, thereby shortening the ice-making cycle. This design also helps form ice cubes of uniform shape and size.

[0068] like Figure 3 As shown, according to one embodiment of the present invention, a sealing member 124 is provided between the water collecting box 108 and the water outlet 104 .

[0069] In one embodiment of the present invention, in order to ensure the sealing and connection stability between the water collecting box 108 and the ice making mold 102 , a sealing member 124 is provided between the water collecting box 108 and the water outlet 104 .

[0070] Seal 124, a specially designed connection component, primarily prevents water leakage from the connection between water collection box 108 and ice mold 102. In this embodiment, seal 124 is installed at the interface between water collection box 108 and water outlet 104. Its unique elasticity or plasticity allows it to fit tightly against the two connecting surfaces, forming an effective waterproof barrier.

[0071] The seal 124 has sufficient corrosion resistance, wear resistance, and high temperature resistance to ensure a stable sealing effect during long-term use. At the same time, the design of the seal 124 also needs to take into account the convenience of installation and removal so that it can be maintained and replaced when necessary.

[0072] By providing a seal 124 between the water collection box 108 and the water outlet 104, water leakage can be effectively prevented, not only keeping the interior of the ice maker clean and dry, but also avoiding water waste and potential safety hazards. The provision of seal 124 also improves the sealing performance at the connection between the water collection box 108 and the ice mold 102, enhancing the stability of the connection between the water collection box 108 and the water outlet 104, helping to reduce leakage caused by loose connections or vibration, thereby extending the service life of the device.

[0073] like Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the outer side of the water supply tank 106 is coated with a first insulation layer 126; and / or,

[0074] The outer side of the heating assembly is covered with a second thermal insulation layer 128 .

[0075] In one embodiment of the present invention, in order to improve the energy efficiency and stability of the ice maker, the outer side of the water supply tank 106 and / or the heating component is insulated.

[0076] Specifically, the outer side of the water supply tank 106 is covered with a first insulation layer 126, and the outer side of the heating component is covered with a second insulation layer 128 (or both are subjected to insulation treatment).

[0077] First insulation layer 126 tightly wraps around the outside of water supply tank 106, forming an effective thermal barrier. First insulation layer 126 can be made from a variety of materials, such as polyurethane foam or rubber-plastic insulation materials, which offer excellent thermal insulation and insulation properties. This insulation reduces heat exchange between the water inside water supply tank 106 and the surrounding environment, thereby maintaining a stable water temperature.

[0078] Second insulation layer 128 is tightly wrapped around the outside of the heating element, also forming an effective thermal barrier. The material and structure of second insulation layer 128 are similar to those of the insulation layer of water supply tank 106. The insulation effect of second insulation layer 128 can reduce heat loss from the heating element, improve heating efficiency, and reduce energy consumption.

[0079] The insulation of the water supply tank 106 and the heating assembly reduces heat loss, making it easier to maintain a stable water temperature. This helps reduce the number of times the heating assembly needs to be started and the operating time, thereby reducing energy consumption. The provision of these various insulation layers can reduce the impact of the external environment on the water supply tank 106 and the heating assembly, making the water temperature more stable, helping to maintain stable operation of the ice maker and reducing failures and downtime caused by water temperature fluctuations.

[0080] like Figure 1 As shown, according to one embodiment of the present invention, the heating assembly includes:

[0081] A heat conducting member 130 is mounted on the housing 100;

[0082] The heating wire is disposed on the heat conducting member 130 .

[0083] In one embodiment of the present invention, the heating assembly is refined to improve heating efficiency and temperature control accuracy. The heating assembly mainly includes a heat conductor 130 and a heating wire, which together achieve efficient heating.

[0084] Thermal conductor 130 is installed within housing 100 and is typically made of a material with high thermal conductivity, such as metal or alloy, to ensure rapid and uniform heat transfer to the external environment. The shape and size of thermal conductor 130 can be customized based on specific application requirements to accommodate different heating scenarios.

[0085] The heating wire is mounted on the heat conducting member 130 and can be made of a resistance wire. When current flows through the resistance wire, it generates heat, which is then transferred to the external environment through the heat conducting member 130. Parameters such as the resistance value, length, and diameter of the heating wire can be adjusted based on heating needs and power requirements to achieve the optimal heating effect.

[0086] In specific implementation, the heat conducting member 130 and the heating wire can be combined together in a variety of ways. For example, they can be fixed together by welding, pasting or other mechanical connection methods to ensure close contact and good heat transfer effect between them.

[0087] The heat conductor 130 has high thermal conductivity and can quickly transfer the heat generated by the heating wire to the external environment, which helps to reduce heat loss and waste and improve heating efficiency. By adjusting parameters such as the resistance value, length and diameter of the heating wire, the heating power and temperature can be precisely controlled, allowing the heating component to adapt to different heating requirements and temperature ranges and achieve precise temperature control. The close contact between the heat conductor 130 and the heating wire and the good heat transfer effect help reduce problems such as thermal stress and thermal deformation, help enhance the stability and reliability of the heating component, and extend its service life.

[0088] In addition, the structure of the heating component is relatively simple and easy to disassemble and clean, which reduces maintenance costs and time and improves the overall economic benefits of the equipment.

[0089] A second embodiment of the present invention provides a refrigeration device, comprising a refrigeration compartment, in which the above-mentioned ice maker is arranged.

[0090] The refrigeration room is used to provide a low-temperature environment to preserve food, beverages, or other items that need to be refrigerated. The ice maker is installed in the refrigeration room and connected to the refrigeration system of the refrigeration room to use the cold source provided by the refrigeration system to make ice.

[0091] The refrigeration system of the refrigeration equipment and the refrigeration system of the ice maker work together to ensure that ice cubes can be made efficiently while providing sufficient refrigeration space.

[0092] In addition, the refrigeration equipment can also be equipped with a user interface to display status information of the refrigeration compartment and ice maker, such as temperature, ice making progress, etc.

[0093] By integrating the ice maker into the refrigeration unit, the space in the refrigeration compartment is fully utilized, eliminating the additional space required for a separate ice maker. The synergistic operation of the refrigeration unit and ice maker ensures efficient cooling and ice-making, reducing energy consumption and ice-making time. By integrating the ice maker, the refrigeration unit not only has refrigeration functions but also ice-making capabilities, meeting the diverse needs of users.

[0094] Finally, it should be noted that the above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
