Thanks to the high thermal conductivity of the metal molds, ice cubes are quickly formed. However, once the ice is formed, the metal ice molds can become difficult to remove.

[0056] The technical solutions in the embodiments (or "implementations") of this application will now be clearly and completely described with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0057] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0058] Please see Figure 1 and Figure 2 This application provides a vehicle refrigerator, including a shell 4, a cooling chamber 2, an ice-making chamber 3, and an ice-making device 1. The cooling chamber 2 and the ice-making chamber 3 are each independently disposed within the shell 4. The ice-making device 1 is disposed within the ice-making chamber 3. The ice-making device 1 includes a rigid ice-making box 10 and a flexible ice cover 11, wherein the thermal conductivity of the rigid ice-making box 10 is greater than that of the flexible ice cover 11. The rigid ice-making box 10 has an opening 101. The flexible ice cover 11 covers the opening 101, and together with the interior of the rigid ice-making box 10, forms an ice-making space.

[0059] Please see Figure 2 and Figure 3 The flexible ice cap 11 has an ice-adhesive surface 111 on the side facing the interior of the rigid ice container 10. This surface is configured to adhere ice when the flexible ice cap 11 is separated from the rigid ice container 10. In other words, when the flexible ice cap 11 covers the opening 101 of the rigid ice container 10, the ice-adhesive surface 111 faces the interior of the rigid ice container 10 to be in contact with the liquid surface.

[0060] Because the thermal conductivity of the rigid ice container 10 is greater than that of the flexible ice cap 11, the rigid ice container 10 can quickly complete the ice-making process, ensuring high ice-making efficiency. During the ice removal process, the rigid ice container 10 has a faster heat transfer process than the flexible ice cap 11, causing the ice in the rigid ice container 10 to melt quickly. However, because the heat transfer process of the flexible ice cap 11 is relatively slow, the ice, even after melting and separating from the rigid ice container 10, has not yet separated from the flexible ice cap 11, allowing the ice to remain firmly attached to the ice-adhesive surface 111 of the flexible ice cap 11. Therefore, the flexible ice cap 11 can carry the ice away from the rigid ice container 10, facilitating subsequent ice removal by deforming the flexible ice cap 11, thus reducing the difficulty of ice removal.

[0061] This application breaks through the traditional design limitation of only being able to use "ice molds for ice removal". By using the ice-adhesive surface 111 of the flexible ice cover 11 to adhere ice blocks, it is easy to remove ice by utilizing the deformation of the flexible ice cover 11. Ice removal can be easily achieved without affecting the original high ice-making efficiency of the rigid ice box 10.

[0062] It should be noted that the rigid ice container 10 can be made of metal materials, such as, but not limited to, aluminum alloy or stainless steel. Of course, the rigid ice container 10 can also be made of non-metallic materials such as ceramic. The flexible ice mold can be made of flexible polymer materials, such as, but not limited to, rubber or plastic.

[0063] In one embodiment, the flexible ice cap 11 is further configured to elastically deform under an external force after being separated from the rigid ice-making box 10, causing the ice to detach. This external force can be provided by a mechanical power source or manually by the user. Thus, ice detachment is achieved by causing the flexible ice cap 11 to elastically deform, and after the force is removed, the flexible ice cap 11 can return to its original shape for use in the next ice-making process. Exemplarily, the external force can be a force capable of causing at least a portion of the flexible ice cap 11 to rotate about an axis, resulting in torsional deformation. Of course, the external force can also be a force acting on different locations of the flexible ice cap 11, causing at least a portion of the flexible ice cap 11 to bend.

[0064] Please continue reading. Figure 1 and Figure 2 In one embodiment, the ice-making chamber 3 includes an ice-making area 31 and an ice-storage area 32; the flexible ice cover 11 is provided with a handle 117. The ice-making device 1 has an ice-making position and an ice-removing position; in the ice-making position, the ice-making device 1 is located in the ice-making area 31 to make ice. In the ice-removing position, the flexible ice cover 11 is moved to the ice-storage area 32 with the ice-adhering surface 111 facing inwards towards the ice-storage area 32. When the handle 117 is subjected to the external force, the flexible ice cover 11 undergoes elastic deformation, causing the ice block B to fall into the ice-storage area 32. Thus, the flexible ice cover 11 can be easily moved using the handle 117, and during the ice removal process, the flexible ice cover 11 can be easily torsional deformed as a force point. Figure 3 As shown, in one embodiment, the handle portion 117 includes two handles 1171, which are symmetrically arranged on both sides of the flexible ice cover 11. This allows for balanced force distribution on both sides of the flexible ice cover 11, facilitating the removal of ice from the flexible ice cover 11 and improving de-icing efficiency.

[0065] Please see Figure 3 and Figure 4In one embodiment, the vehicle-mounted refrigerator further includes a drive assembly 12. The drive assembly 12 is tractively connected to the flexible ice cover 11 and is used to drive the flexible ice cover 11 between an ice-making position and an ice-removing position. Thus, when the drive assembly 12 drives the flexible ice cover 11 to the ice-making position, the flexible ice cover 11 can cover the rigid ice-making box 10 and participate in the ice-making process together with the rigid ice-making box 10. When the drive assembly 12 drives the flexible ice cover 11 to the ice-removing position, it facilitates the removal of ice from the flexible ice cover 11.

[0066] Please see Figure 4 and Figure 5 In one embodiment, the drive assembly 12 includes a drive mechanism 121 and a transmission mechanism 122. The output end of the drive mechanism 121 is driveably connected to the transmission mechanism 122, and the transmission mechanism 122 is also driveably connected to the flexible ice cover 11.

[0067] The power of the drive mechanism 121 is transmitted to the flexible ice cover 11 via the transmission mechanism 122. Under the action of the power transmitted by the transmission mechanism 122, the flexible ice cover 11 can translate along a curve between the ice-making position and the ice-removing position. Thus, during the translation along the curve, the posture of the flexible ice cover 11 can remain basically unchanged, allowing the ice to adhere stably to the ice-adhesive surface 111 of the flexible ice cover 11, minimizing the possibility of the flexible ice cover 11 rotating along its own axis during movement, thereby preventing the ice from accidentally falling off before reaching the ice-removing position.

[0068] Please continue reading. Figure 4 and Figure 5 In one embodiment, the transmission mechanism 122 includes a dual-rocker structure; one rocker in the dual-rocker structure is the master rocker 122a, and the other rocker is the slave rocker 122b; the first end of the master rocker 122a is rotatably connected to the output end of the drive mechanism 121, and the second end is rotatably connected to the flexible ice cover 11; the first end of the slave rocker 122b is rotatably connected to the outer shell 4, and the second end is rotatably connected to the flexible ice cover 11; both the master rocker 122a and the slave rocker 122b reciprocate around their own first-end rotation axis, so that the flexible ice cover 11 translates along a curve between the ice-making position and the ice-removing position. Thus, the dual-rocker structure, the flexible ice cover 11, and the outer shell 4 can form a planar four-bar linkage mechanism, in which the movement of one master rocker 122a can be controlled by one drive mechanism 121, and the slave rocker 122b can follow the master rocker 122a to achieve translation of the flexible ice cover 11. The structure is simple and occupies little space.

[0069] In another example, both rockers in the dual-rocker structure can be active rockers 122a (not shown in the figure). The first ends of both active rockers are rotatably connected to the output end of the drive mechanism 121, and the second ends are rotatably connected to the flexible ice cover 11. Both active rockers reciprocate around their own first-end rotation axis, causing the flexible ice cover 11 to translate along a curve between the ice-making position and the ice-removing position. Thus, the movement of the two active rockers 122a can be controlled one-to-one by the two drive mechanisms 121 to evenly distribute the load and make the ice removal process smoother.

[0070] Of course, based on the process of the drive mechanism 121 (e.g., but not limited to a drive motor) driving the transmission mechanism 122 to drive the flexible ice cover 11 to translate along the curve, it can be understood that in other embodiments, the transmission mechanism 122 may also include a cam structure or other planar multi-link mechanism, as long as it can realize the conversion of the rotational force of the drive mechanism 121 into a swinging force, thereby driving the flexible ice cover 11 to translate along the curve. Those skilled in the art can make specific structural designs as needed, which will not be described in detail here.

[0071] Please continue reading. Figure 4 and Figure 5 In one embodiment, the drive assembly 12 further includes a follower rod 123. The follower rod 123 and the dual rocker structure are located on opposite sides of the flexible ice cover 11. The first end of the follower rod 123 is rotatably connected to the outer shell 4, and the second end is rotatably connected to the flexible ice cover 11. The two rockers in the dual rocker structure are symmetrically distributed relative to the follower rod 123, and the follower rod 123 swings synchronously with the two rockers. Thus, by following the movement of the follower rod 123, the swaying of the flexible ice cover 11 during translation can be minimized, further reducing the risk of ice blocks accidentally falling off.

[0072] Please continue reading. Figure 4 and Figure 5 In one embodiment, the vehicle-mounted refrigerator further includes a torsion stop 14. The ice-making chamber 3 is provided with an ice-making area 31 and an ice-storage area 32. The rigid ice-making box 10 is disposed within the ice-making area 31, and the torsion stop 14 is disposed within the ice-storage area 32.

[0073] The flexible ice sheet 11 has a first motion state and a second motion state. In the first motion state, the flexible ice sheet 11 has a first direction A (e.g., Figure 5 As shown in direction A, the ice is translated along the curve to separate from the rigid ice-making box 10, and from the ice-making area 31 to the ice-storage area 32. Figure 4 The torsion stop 14 shown abuts against each other to reach the de-icing position.

[0074] In the second motion state, the flexible ice sheet 11 continues in the first direction A (e.g., Figure 4 The flexible ice sheet 11 is translated along the curve in direction A (as shown) to cause it to twist and detach. Thus, the torsion stop 14 provides resistance to the moving flexible ice sheet 11, facilitating its twisting.

[0075] It should be noted that the specific structure of the torsion stop 14 is not specifically limited here. It can also be a cylindrical, square column or other symmetrical structure, or other irregular structure.

[0076] Please see Figure 6 In one embodiment, the vehicle refrigerator includes an ice-removing switch 17. After the second end of the follower rod 123 abuts against the ice-removing switch 17, it indicates that the flexible ice cover 11 has been translated along a curve in the first direction A to reach a designated position. It then continues to translate along the curve in the first direction A to its final position, causing the flexible ice cover 11 to twist under the constraint of the torsion stop 14, thus detaching the ice from the flexible ice cover 11 and completing the ice removal process. In other embodiments, the vehicle refrigerator also includes an ice-making switch 18. After the second end of the follower rod or the flexible ice cover 11 abuts against the ice-making switch 18, it indicates that the flexible ice cover 11 has been placed inside the rigid ice-making box 10, and the subsequent ice-making process can be executed.

[0077] It should be noted that both the de-icing switch 17 and the ice-making switch 18 can be located on the outer casing, but the specific design positions of the de-icing switch 17 and the ice-making switch 18 are not limited here.

[0078] Please see Figure 2 and Figure 7 In one embodiment, the rigid ice box 10 has multiple ice trays 103 formed inside; the flexible ice cover 11 has an overflow groove 113 formed on the side opposite to the ice trays 103, and the flexible ice cover 11 is also provided with a through hole 114 for communicating between the ice trays 103 and the overflow groove 113. Thus, during the process of water crystallizing in the rigid ice box 10, water that needs to be drained due to the increasing size of the ice crystals can flow from the through hole 114 into the overflow groove 113, and air bubbles can also escape outward from the through hole 114.

[0079] Please continue reading. Figure 7 In one embodiment, a raised structure 115 is also formed within the overflow trough 113; the flexible ice cover 11 has a plurality of through holes 114; the raised structure 115 is located between two adjacent through holes 114. Therefore, when the flexible ice grid 103 deforms, the portion of the ice layer formed within the overflow trough 113 that contacts the raised structure 115 is more easily broken, reducing the difficulty of cleaning the ice layer within the overflow trough 113 of the flexible ice cover 11.

[0080] It should be noted that the specific shape of the protrusion structure 115 is not specifically limited here. For example, it can be a cylindrical or polygonal symmetrical structure, or a petal-shaped or asymmetrical structure.

[0081] Please see Figure 8 and Figure 9 In one embodiment, the flexible ice sheet 11 has at least two ice block adjusting portions 116 on the ice-adhesive surface 111; each ice block adjusting portion 116 faces a different ice grid 103, and the heights of each ice block adjusting portion 116 extending from the ice-adhesive surface 111 are different, for supporting ice blocks of different sizes. For example, as... Figure 8 As shown, the ice-adjusting part 116 can be a protrusion formed on the ice-sticking surface 111 to create cylindrical structures of varying heights. During the ice-making process, multiple cylindrical structures of different heights can contact different liquid surfaces to produce ice cubes of different sizes. Of course, in other examples, such as... Figure 9 As shown, the ice adjustment section 116 can also be formed by extending the self-adhesive ice surface 111 further into each ice grid 103, creating multiple surfaces of varying heights for contact with different liquid surfaces. It is understood that the specific structural design of the ice adjustment section 116 is not limited to this and can be appropriately adjusted according to actual needs.

[0082] In one embodiment, the inner wall of the rigid ice container 10 is provided with a water filling scale line (not shown in the figure). The flexible ice cover 11 includes an ice cover body 110, and the ice-adhesive surface 111 protrudes from the inner side of the ice cover body 110. When the flexible ice cover 11 covers the rigid ice container 10, the ice-adhesive surface 111 is flush with the water filling scale line. Alternatively, the distance between the ice-adhesive surface 111 and the ice cover body 110 is greater than the distance between the water filling scale line and the ice cover body 110. In other words, in the direction from which the flexible ice cover 11 points to the rigid ice container 10, when the flexible ice cover 11 covers the rigid ice container 10, the height of the ice-adhesive surface 111 is below the water filling scale line, that is, relative to the water filling scale line, the ice-adhesive surface 111 is closer to the bottom wall of the rigid ice container 10. Therefore, when the water in the rigid ice box 10 reaches the water filling mark, the ice-adhesive surface 111 of the flexible ice cover 11 can come into contact with the water. Excess water can be discharged from the through hole 114 into the overflow tank 113, so that the multiple ice compartments 103 are filled with water and the water volume is uniform, so as to make regular ice blocks without obvious defects or protrusions. B

[0083] Please continue reading. Figure 2In one embodiment, the four edges 102 of the rigid ice container 10 form the opening 101; the flexible ice cap 11 has an annular sealing groove (not shown in the figure) on its surface facing the opening 101, and the four edges 102 are embedded in the annular sealing groove. This improves the sealing performance of the rigid ice container 10 and the flexible ice cap 11. In other examples, a sealing ring made of flexible material can be provided within the sealing groove to further improve the sealing performance of the rigid ice container 10 and the flexible ice cap 11.

[0084] Please see Figure 10 and Figure 11 In one embodiment, the vehicle refrigerator further includes a condenser 61, a refrigeration evaporator 62, an ice-making evaporator 63, and a compressor 64. The condenser 61 is disposed within the outer casing 4. The refrigeration evaporator 62 is disposed within or surrounds the refrigeration chamber 2 and communicates with the condenser 61. The ice-making evaporator 63 is disposed within the ice-making chamber 3 and communicates with the condenser 61; the ice-making evaporator 63 is tightly fitted or fixedly connected to the rigid ice-making box 10. The compressor 64 is disposed within the outer casing 4, with its input end communicating with both the refrigeration evaporator 62 and the ice-making evaporator 63, and its output end communicating with the condenser 61. Thus, by arranging the refrigeration evaporator 62 and the ice-making evaporator 63 in parallel and configuring them to communicate with both the condenser 61 and the compressor 64, when the vehicle refrigerator needs to cool the refrigeration chamber 2, the refrigerant enters the refrigeration evaporator 62 via the compressor 64 and the condenser 61 to cool the refrigeration chamber 2. When the vehicle refrigerator needs to cool the ice-making chamber 3, the refrigerant enters the ice-making evaporator 63 via the compressor 64 and the condenser 61 to cool the ice-making chamber 3.

[0085] Please continue reading. Figure 10 In one embodiment, the vehicle refrigerator further includes a three-way valve 65; the input end of the three-way valve 65 is connected to the output end of the compressor 64, the first output end of the three-way valve 65 is connected to the ice-making evaporator 63, and the second output end of the three-way valve 65 is connected to the condenser 61. Thus, when the ice-making device needs to defrost, the refrigerant can directly enter the ice-making evaporator 63 from the output end of the compressor 64 through the three-way valve 65, raising the temperature of the ice-making evaporator 63 and heating the rigid ice-making box 10, facilitating defrosting.

[0086] Please continue reading. Figure 10In one embodiment, the vehicle-mounted refrigerator further includes two capillary tubes 66. One capillary tube 66 is disposed between the refrigeration evaporator 62 and the condenser 61, and is connected to both the refrigeration evaporator 62 and the condenser 61. The other capillary tube 66 is disposed between the ice-making evaporator 63 and the condenser 61, and is connected to both the ice-making evaporator 63 and the condenser 61. Thus, the capillary tubes 66 can be used to achieve throttling and pressure reduction, so that the refrigerant output from the condenser 61 becomes a low-pressure liquid at the capillary tube 66, and then enters the refrigeration evaporator 62 and / or the ice-making evaporator 63 to cool the refrigeration chamber 2 and / or the ice-making chamber 3.

[0087] It should be noted that the refrigerant flow direction can be controlled using the electric valve 67. Furthermore, refrigerants typically contain some moisture and impurities; a dryer filter 68 can be used to dry the moisture in the refrigerant and filter out the impurities.

[0088] In one embodiment, the vehicle-mounted refrigerator further includes a heating device (not shown in the figure); the heating device is disposed within the ice-making chamber 3 and is tightly fitted or fixedly connected to the rigid ice-making box 10. Thus, when the ice-making device 1 needs to remove ice, hot air can be injected into the rigid ice-making box 10 through the heating device, causing the ice to separate from the rigid ice-making box 10 without separating from the flexible ice cover 11, facilitating subsequent twisting and ice removal of the flexible ice cover 11. The heating device includes, but is not limited to, at least one of a heating tube, a heater, and a heating plate.

[0089] Please see Figure 1 In one embodiment, the vehicle refrigerator further includes a support plate 5 movably connected to the side of the outer casing 4. The support plate 5 has an unfolded state and a retracted state; in the unfolded state, the support plate 5 moves to be flush with the horizontal plane; in the retracted state, the support plate 5 moves to abut against the side wall of the outer casing 4. Thus, when the support plate 5 is in the unfolded state, it can serve as a work surface for users to prepare cold drinks while camping. After use, the support plate 5 is rotated to abut against the side wall of the vehicle refrigerator outer casing 4, making the structure more compact.

[0090] For example, the support plate 5 and the housing 4 can be slidably connected by a sliding device. Of course, in other examples, the support plate 5 and the housing 4 can also be rotatably connected by a rotating device. Specific sliding devices include, but are not limited to, slide rails and slide grooves, and rotating devices include, but are not limited to, rotating shafts and bearing seats. Since sliding connections via sliding devices and rotatable connections via rotating devices are common techniques in the mechanical field, they will not be described in detail here.

[0091] In one embodiment, the vehicle refrigerator further includes a cooling compartment cover 7 and an ice-making compartment cover 8, which are movably connected to the outer casing 4 to cover the cooling compartment 2 and the ice-making compartment 3. The movable connection includes, but is not limited to, sliding connections or rotating connections; since these are common technologies in the mechanical field, they will not be elaborated upon here.

[0092] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
