Description

Technical Field

[0001] This application belongs to the field of ice-making technology, and in particular relates to an ice-making component and an ice maker having the ice-making component. Background Technology

[0002] As people's living standards improve, the demand for ice from individuals and families is also increasing. Ice makers can meet the demand for large-scale ice production, so various types of ice makers have appeared on the market. However, existing ice makers that can directly drop ice can only produce bullet-shaped ice, which cannot meet consumers' desire for other preferred ice shapes. Moreover, bullet ice melts easily and cannot maintain its shape for long. Most existing square ice blocks are made using a continuous, stacked method, meaning the entire block drops together. Users need to break the ice with tools before use, and these tools are often exposed and unsanitary, potentially contaminating the ice. Furthermore, the breaking process is time-consuming and laborious, causing inconvenience for users. Utility Model Content

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of this application is to provide an ice-making component and an ice maker. The ice-making component can make ice blocks of various shapes, and the ice blocks are all independent individuals after being made and can be dropped directly.

[0004] The technical solution adopted in this application embodiment is an ice-making assembly, including a refrigeration component, and further comprising:

[0005] An ice-making container, used to hold water for making ice;

[0006] An ice-making mold is disposed inside the ice-making box and includes multiple independent ice-making compartments. The bottom of each ice-making compartment faces upward and is in contact with the refrigeration component so that the cold energy of the refrigeration component is conducted to the ice-making compartment. The opening of each ice-making compartment faces downward and is open.

[0007] Anti-icing sleeves are respectively fitted over the outside of multiple ice-making chambers to allow the water inside the ice-making chambers to gradually freeze from the inner surface to the center of the chamber.

[0008] In an optional embodiment, the ice-making chamber has a vent at or near its bottom. The vent allows the ice-making chamber to communicate with the outside atmosphere, making it easier for water from the ice-making box to enter the chamber, ensuring the water level in the ice-making chamber is essentially the same as the water level in the ice-making box, and guaranteeing sufficient water for ice production.

[0009] In an optional embodiment, the ice-making mold further includes a top plate, with the refrigeration component attached to the upper surface of the top plate; the ice-making chamber is disposed on the lower surface of the top plate, and the lower surface of the top plate forms the inner surface of the bottom of the ice-making chamber. This allows the cooling energy of the refrigeration component to be effectively and quickly transferred to the ice-making chamber through the top plate.

[0010] In an optional embodiment, the refrigeration component includes a base plate and an evaporator. The evaporator is a bent tubular shape and is mounted on the base plate with its tube wall attached to the upper surface of the base plate. The lower surface of the base plate is in close contact with the upper surface of the top plate. This ensures reliable contact between the ice mold and the evaporator, with a large contact area and good heat transfer effect, allowing the cooling capacity of the evaporator to be quickly and effectively transferred to the ice-making chamber.

[0011] In an optional embodiment, the anti-icing sleeve includes a base and multiple sleeve bodies protruding from the same side of the base. The inner cavities of the multiple sleeve bodies penetrate the base to form multiple openings. The multiple sleeve bodies are fitted onto the outside of the multiple ice-making chambers one-to-one through the multiple openings, and the upper surface of the base is attached to the lower surface of the top plate. This anti-icing sleeve has a simple and reasonable structure and can effectively prevent the cold energy of the refrigeration components from being conducted to the water outside the ice-making chambers; or

[0012] The anti-icing sleeve is composed of a coating formed of a non-thermal-conducting material on the outer surface of the ice-making chamber and the lower surface of the top plate.

[0013] In an optional embodiment, the lower end face of the anti-icing sleeve is flush with or protrudes from the lower end face of the ice-making chamber. This prevents water outside the ice-making chamber from easily freezing, ensuring that ice blocks do not stick together at the opening.

[0014] In an optional embodiment, the ice-making assembly includes a plurality of ice-making molds, the ice-making chambers of the plurality of ice-making molds having the same or different shapes, and the plurality of ice-making molds being interchangeably mounted on the refrigeration component. This allows for the fulfillment of users' needs for ice cubes of different shapes.

[0015] In optional embodiments, the ice-making chambers of the multiple ice-making molds may have shapes including, but not limited to, square, cylindrical, heart-shaped, or polygonal prisms. Various shapes of ice blocks can be produced according to user needs, resulting in diverse ice block shapes and a wider range of products.

[0016] In an optional embodiment, the ice-making mold is made of a thermally conductive material, which includes, but is not limited to, stainless steel, nickel-plated copper, or aluminum alloy.

[0017] The anti-icing sleeve is made of a non-thermal-conducting material, including but not limited to silicone, rubber, or plastic. This ensures that the water inside the ice-making chamber freezes into ice, while the water outside the chamber does not freeze.

[0018] An ice maker includes a raw water tank, a purified water jug, and a refrigeration system, and further includes the ice-making component from any of the above embodiments. The refrigeration system is connected to the refrigeration part of the ice-making component. The ice cubes produced by this ice maker are independent and do not stick together, and can fall directly, eliminating the need for breaking the ice during use and improving the convenience of using ice cubes.

[0019] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: the ice-making mold of the ice-making component of this application has multiple independent ice-making chambers that are formed independently without interfering with each other, resulting in more stable ice block shapes and better forming effects. By changing the ice-making molds with different ice-making chamber shapes, ice blocks of different shapes can be made, which is suitable for making ice blocks of various shapes and meets the needs of different users for ice blocks of different shapes. Moreover, the outer surface of the ice-making chamber is protected by an anti-icing sleeve that does not conduct heat well. The finished ice blocks are all independent individuals that do not stick together and can be dropped directly from the ice-making mold. Consumers can use the ice blocks directly without having to knock them.

[0020] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this application.

[0042] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0043] This application provides an ice-making component 100, which can be applied to an ice maker to make ice cubes 6 by direct drop.

[0044] like Figures 1 to 5 As shown, the ice-making module of this embodiment includes a refrigeration component 1, an ice-making box 2, an ice-making mold 3, and an anti-icing sleeve 4. The ice-making box 2 is used to hold water for ice making. The ice-making mold 3 is disposed inside the ice-making box 2 and includes multiple independent ice-making compartments 32. The bottom of the ice-making compartment 32 faces upward and is in contact with the refrigeration component 1 so that the cold energy of the refrigeration component 1 is conducted to the ice-making compartment 32. The opening of the ice-making compartment 32 faces downward and is open. The anti-icing sleeve 4 is respectively fitted over the multiple ice-making compartments 32 so that the water in the ice-making compartment 32 gradually freezes from the lower temperature inner surface of the compartment (including the inner surface of the bottom of the ice-making compartment 32) towards the center of the compartment. The outer surface of the compartment will not freeze because of the anti-icing sleeve 4, so that the water outside the ice-making compartment 32 will not freeze. In this way, each ice-making compartment 32 forms an independent ice block, and the ice blocks in different ice-making compartments 32 are not connected to each other. The ice-making mold 3 of the ice-making component 100 in this embodiment of the application is provided with multiple independent ice-making chambers 32, and an anti-icing sleeve 4 is provided on the outer sleeve of the ice-making chambers 32. This allows the cold energy of the refrigeration component 1 to be conducted from the bottom of the refrigeration chamber to the ice-making chamber 32. The water in each ice-making chamber 32 freezes gradually from the inner surface to the center of the chamber, and the water outside the ice-making chamber 32 is prevented from freezing. This ensures that the ice blocks 6 made in the multiple independent ice-making chambers 32 do not stick together and can fall directly from the ice-making chamber 32 as individual pieces, without the user having to break the ice blocks 6 to separate them before use.

[0045] In some embodiments, such as Figures 3 to 7As shown, the ice-making chamber 32 has an exhaust vent 321 at or near the bottom. During the ice-making process, when the ice mold 3 is placed into the ice box 2, the water level 21 in the ice box 2 should be lower than the position of the exhaust vent 321, keeping the exhaust vent 321 exposed so that the ice-making chamber 32 is connected to the outside atmosphere, allowing water from the ice box 2 to enter the interior of the ice-making chamber 32 more easily. This ensures that the water level in the ice-making chamber 32 is basically the same as the water level in the ice box 2, and that there is enough water in the ice-making chamber 32 to make ice cubes 6.

[0046] In some embodiments, such as Figures 3 to 5 As shown, the ice-making mold 3 also includes a top plate 31, and the refrigeration component 1 is mounted on the top plate 31 in a manner that fits against the upper surface of the top plate 31. The ice-making chamber 32 is located on the lower surface of the top plate 31, and the lower surface of the top plate 31 forms the inner surface of the bottom of the ice-making chamber 32. In this way, the cold energy of the refrigeration component 1 can be effectively and quickly conducted through the top plate 31 to the ice-making chamber 32, and then to the water in the ice-making chamber 32, causing the water to freeze into ice cubes 6. In addition, since the refrigeration component 1 is located at the bottom of the ice-making chamber 32, the cold energy of the refrigeration component 1 is first conducted to the bottom of the ice-making chamber 32, and then conducted downwards along the side wall of the ice-making chamber 32. In this way, the water in the ice-making chamber 32 freezes into ice cubes 6 from top to bottom and from the inner surface of the chamber to the center. The water in the ice-making box 2 located below the ice-making chamber 32 will not freeze, thus preventing the ice cubes 6 in multiple ice-making chambers 32 from sticking together and keeping them independent.

[0047] For example, the top plate 31 is provided with vents 321 that communicate with the ice chamber 32 for each ice chamber 32. Specifically, the vents 321 can be located near the periphery of the bottom of the ice chamber 32, that is, the edge of the top plate 31. This not only makes the position of the vents 321 higher, ensuring the water level in the ice chamber 32, but also prevents the vents 321 from being blocked by the bottom plate 11 of the refrigeration component 1 and affecting the exhaust.

[0048] Continue to combine Figures 3 to 5 The refrigeration component 1 includes a base plate 11 and an evaporator 12. The evaporator 12 is a bent tubular shape, and its tube wall is attached to the upper surface of the base plate 11. For example, the evaporator 12 can be bent into a U-shape or an S-shape to provide a longer evaporator 12 on the limited upper surface of the base plate 11, thus providing sufficient cooling capacity to quickly freeze the water in the ice-making chamber 32. The lower surface of the base plate 11 is in close contact with the upper surface of the top plate 31, so that the ice-making mold 3 can achieve reliable contact and connection with the evaporator 12 through the base plate 11 and the top plate 31 (such as welding or wire connection). The larger the contact area, the better the heat transfer effect, and the cooling capacity of the evaporator 12 can be quickly and effectively transferred to the ice-making chamber 32.

[0049] In some embodiments, such as Figures 3 to 5As shown, the anti-icing sleeve 4 includes a base 41 and multiple sleeves 42 protruding from the same side of the base 41. The inner cavities of the multiple sleeves 42 penetrate the base 41 to form multiple openings 43. The multiple sleeves 42 are fitted onto the multiple ice-making chambers 32 one-to-one through the multiple openings 43, and the upper surface of the base 41 is attached to the lower surface of the top plate 31. That is, the lower surface of the top plate 31 where no ice-making chamber 32 is installed is completely covered by the base 41. This anti-icing sleeve 4 has a simple and reasonable structure, is easy and quick to install on the ice-making chambers 32, and can effectively isolate the cold energy of the refrigeration component 1 from the water outside the ice-making chambers 32, ensuring that only the water in the ice-making chambers 32 can freeze into ice blocks 6, achieving independent and non-sticky ice blocks 6.

[0050] The base 41 and the sleeve 42 can be an integral structure. The shape of the sleeve 42 is adapted to the shape of the ice maker 32 and tightly wraps around the outside of the ice maker 32 to prevent water from the ice maker 2 from entering between the sleeve 42 and the ice maker 32.

[0051] It is understandable that the way the anti-icing sleeve 4 is set on the ice-making mold 3 is not limited to Figures 3 to 5 The ice-making chamber 32 is fitted with a sleeve 42. For example, the ice-making chamber 32 can also be formed by coating a non-thermal-conducting material on the outer surface of the ice-making chamber 32 to form an anti-icing sleeve 4.

[0052] For example, the lower end face of the sleeve 42 of the anti-icing sleeve 4 is flush with or protrudes from the lower end face of the ice-making chamber 32. In this way, the water inside the ice-making chamber 32 near the opening can freeze, while the water outside the opening is not easy to freeze, ensuring that the ice blocks 6 will not stick together at the opening.

[0053] In some embodiments, the ice-making mold 3 and the cooling component 1 are detachably connected. For example, the ice-making mold 3 and the cooling component 1 can be detachably connected via a connector 5, which can be a bolt or screw, etc. Specifically, such as... Figure 3 and Figure 6 As shown, the bottom plate 11 of the refrigeration component 1 is provided with a plurality of first connecting holes 111, and the top plate 31 of the ice-making mold 3 is provided with a plurality of second connecting holes 311. The plurality of second connecting holes 311 correspond one-to-one with the plurality of first connecting holes 111 and are respectively fitted with screws to fix the top plate 31 to the bottom plate 11 and make the two fit tightly together.

[0054] Furthermore, continue to combine Figure 3 and Figure 6 The base 41 of the anti-icing sleeve 4 is provided with a plurality of third connecting holes 411 corresponding one-to-one with the plurality of second connecting holes 311 on the top plate 31 of the ice-making mold 3. Screws pass through the third connecting holes 411 to fix the base 41 to the top plate 31 and make the two fit tightly together.

[0055] The ice-making assembly 100 may include a plurality of ice molds 3, which are interchangeably mounted on the refrigeration component 1. In this way, by designing ice molds 3 with different shapes and / or sizes of ice chambers 32, the purpose of producing ice blocks 6 of different shapes and / or sizes can be achieved.

[0056] The ice-making chambers 32 of multiple ice-making molds 3 can have the same or different shapes, and the ice-making chambers 32 on the same ice-making mold 3 can also have the same or different shapes. The shapes of the ice-making chambers 32 include, but are not limited to, square, cylindrical, heart-shaped or triangular prism shapes.

[0057] Figure 3 The ice mold 3 of the illustrated embodiment 1 has multiple ice chambers 32 with the same shape and all of them are square, and the ice blocks 6 produced by it are also square in shape.

[0058] Figure 4 The ice mold 3 of the illustrated embodiment 2 has multiple ice chambers 32 with the same shape and all of them are cylindrical, and the ice blocks 6 produced by it are also cylindrical.

[0059] Figure 5 The ice mold 3 shown in Embodiment 3 has multiple ice chambers 32 with the same shape and all of them are heart-shaped, and the ice blocks 6 produced by it are also heart-shaped.

[0060] Understandably, the ice-making chamber 32 can also be triangular prism, pentagonal prism, etc., and the ice blocks 6 produced from it can also be triangular prism, pentagonal prism, etc. Furthermore, multiple ice-making chambers 32 on the same ice-making mold 3 can have different shapes; for example, some ice-making chambers 32 can be square, while others can be cylindrical. Thus, using the same ice-making mold 3, two or more different shapes of ice blocks 6 can be produced simultaneously.

[0061] The top plate 31 and ice-making chamber 32 of the ice-making mold 3 should both be made of thermally conductive material so that the cooling capacity of the refrigeration component 1 can be effectively and quickly transferred into the ice-making chamber 32. The bottom plate 11 and evaporator 12 of the refrigeration component 1 are also made of thermally conductive material. Thermally conductive materials include, but are not limited to, stainless steel, nickel-plated copper, or aluminum alloy.

[0062] The anti-icing sleeve 4 should be made of a non-thermal conductive material to prevent cold energy from being conducted to the water outside the ice-making chamber 32. Non-thermal conductive materials include, but are not limited to, silicone, rubber, or plastic materials.

[0063] The ice-making component 100 of this application designs multiple independent ice-making chambers 32 on the ice-making mold 3. The multiple ice-making chambers 32 are formed independently without interfering with each other, resulting in a more stable shape of ice cubes 6, better forming effect, and less tendency to melt.

[0064] The outer surface of the ice chamber 32 is protected by an anti-icing sleeve 4 made of a non-thermal conductive material. This allows ice to form only inside the ice chamber 32. After the ice is made, the ice cubes 6 are all independent and will not stick together. The ice cubes 6 can fall directly from the ice mold 3 without the user having to break them before use.

[0065] The ice-making component 100 can be replaced with ice molds 3 with ice chambers 32 of different shapes, so that the ice cubes 6 produced can have more diverse shapes and the variety of products can be increased.

[0066] This application also provides an ice maker, which includes a raw water tank 10, a pure water jug ​​20, a refrigeration system, and an ice-making component 100 as described in any of the above embodiments. The refrigeration system is connected to the refrigeration component 1 of the ice-making component 100 and is used to provide refrigerant to the evaporator 12 of the refrigeration component 1. The ice cubes 6 produced by the ice maker of this application are independent and do not stick together, and can fall directly, eliminating the need for breaking the ice during use and improving the convenience of using the ice cubes 6.

[0067] like Figure 8 As shown, the refrigeration system includes a compressor 30 and a condenser 40. After the compressor 30 starts, it draws in low-pressure, low-temperature gaseous refrigerant and transforms it into a high-pressure, high-temperature gas through compression. This high-temperature, high-pressure gas flows to the condenser 40, where it exchanges heat with external air or water, cooling the refrigerant and turning it into a liquid state. The liquid refrigerant then enters the evaporator 12 through an expansion valve or capillary tube 50. At this point, due to the rapid drop in pressure and temperature of the liquid refrigerant, it begins to change from a liquid to a gaseous state and absorbs heat from the water in the ice-making chamber 32 within the evaporator 12, causing the water in the ice-making chamber 32 to freeze rapidly and form ice blocks 6. At this point, the refrigerant has been transformed into a low-pressure, low-temperature gaseous state and re-enters the compressor 30 for the next cycle.

[0068] The working principle of the ice maker: Water in the raw water tank 10 is continuously fed into the pure water jug ​​20 after being filtered by the filter element 80 under the action of the booster pump 70. The pure water jug ​​20 and the connector allow water to flow into the ice maker 2 through the overflow pipe. The water in the ice maker 2 enters the ice-making chamber 32 of the ice mold 3. At the same time, the compressor 30 and the condenser 40 work, and the evaporator 12 begins to cool. When the temperature of the evaporator 12 is below 0 degrees Celsius, the temperature of the ice mold 3, which is installed with the evaporator 12, also drops. When the temperature of the independent ice-making chamber 32 on the ice mold 3 is also below 0 degrees Celsius, water begins to freeze inside the ice-making chamber 32. The compressor 30 continues to work, and the temperature of the evaporator 12 continues to decrease. When the temperature reaches -8 degrees Celsius or lower, a complete ice block 6 is formed inside each ice-making chamber 32. At this time, the ice block 6 inside the ice-making chamber 32 has been made. Then the compressor 30 stops cooling, the de-icing valve 60 closes, and the evaporator 12 begins to heat up rapidly, draining the unfrozen water from the ice-making box 2. When the temperature of the evaporator 12 is above 0 degrees Celsius, the surface where the ice cube 6 and the ice-making chamber 32 are in contact melts rapidly into a water layer, and the ice cube 6 detaches and falls directly down (it can fall directly into the ice-making box 2, and then be poured from the ice-making box 2 into the ice-receiving box 90, or the ice-making box 2 can be moved away from the bottom of the ice-making chamber 32, so that the ice cube 6 in the ice-making chamber 32 falls directly into the ice-receiving box 90 below). At this time, ice making is completed.

[0069] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
