Description

Technical Field

[0001] This invention relates to the field of ice makers, specifically a portable ice maker. Background Technology

[0002] With the development of technology, refrigeration equipment has developed an ice maker with automatic ice-making function based on the working principle of a refrigerator. The existing technology disclosed in the existing ice maker, such as the "Ice Making Device and Refrigeration Equipment" in Chinese Patent Application No. CN202223452497.X, discloses in paragraph 0050 that the ice making device includes a water injection box, an isolation box, and an ice making mechanism. The ice making mechanism has an ice making column that passes through the water injection box. The isolation box is located on one side of the ice making column, and the isolation box and the water injection box are arranged sequentially along the direction of the ice making column. In this structure, the water injection box and the ice making column are set separately. The ice making column can pass through the water injection box through the assembly connection. Therefore, a sealing structure must be set between the ice making column and the water injection box to seal the gap between the two and prevent water leakage.

[0003] However, with prolonged use and aging, as well as frequent thermal expansion and contraction, it is difficult to ensure its sealing effect, and leakage may still occur. Furthermore, setting up a sealing structure requires additional installation steps, reducing the production efficiency of the ice maker and increasing production costs. In addition, the distance between the two connected ice columns is relatively short, and the drinking water between the two adjacent ice columns absorbs heat from both sides simultaneously, thus freezing faster than in other areas. This eventually causes adjacent ice blocks on the ice column to condense into one piece. After the user removes the ice block from the ice column using the ice box, they still need to break up the condensed ice blocks before they can be used. This is time-consuming, and during the breaking up process, the ice blocks may come into contact with the user's hands, becoming contaminated with dirt or bacteria, affecting hygiene. Therefore, the applicant provides a new solution that can replace the above-mentioned existing technology through structural improvements and refinements, for consumers to choose from. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned existing problems and provide a portable ice maker with a simple and reasonable structure. Its main function is to make the connection between the water injection box and the ice mold column more firm and reliable, eliminate the need for a sealing structure between the two, and separate adjacent ice particles through a partition structure to prevent adjacent ice particles from condensing into one.

[0005] A portable ice maker includes a casing. Inside the casing are a control device, a refrigeration device, and an ice-removing device. The refrigeration device includes a compressor electrically connected to the control device. A condenser, a dryer, a capillary tube, and an ice-making evaporator are sequentially connected to the compressor along a main refrigerant pipe. The ice-making evaporator includes at least a water-filling box made of metal. The water-filling box contains a water storage chamber. Several spaced-apart ice-making molds are integrally connected to the water-filling box via sheet metal. An ice tray is detachably fitted into the water storage chamber. The tray body has several partition structures for separating the inner cavity of the ice tray, with adjacent partition structures defining independent ice-making zones. The ice-making molds extend into the corresponding ice-making zones, and a flow channel component is connected to the bottom surface of the water-filling box. A cavity is provided between the flow channel component and the ice-making mold column. The flow channel component has a recessed groove on its end face facing the water injection box. The flow channel component defines a refrigerant flow channel connecting the cavities of each mold column through the component groove and the water injection box.

[0009] As a further embodiment, the ice-making mold column is integrally stretched upward from the bottom wall of the water injection box to form an upper chamber with an open bottom; the component groove includes several recessed cavities and several connecting grooves, the several recessed cavities correspond one-to-one with the upper chamber and together enclose the inner cavity of the mold column, and adjacent two recessed cavities are connected by connecting grooves.

[0010] As a further embodiment, the flow channel component includes a metal base plate, which is formed into a component groove by sheet metal processing, and the metal base plate is welded to the bottom surface of the water injection box.

[0011] As a further embodiment, the control device includes a rechargeable battery pack, a control box, and a control circuit board.

In addition, the rotary compressor is driven by DC power and has low energy consumption. Therefore, the power supply needs can be met by a battery pack built into the ice maker. Furthermore, the various refrigeration components are arranged in different positions on the periphery of the rotary compressor, which can make reasonable use of the internal space of the ice maker, making the ice maker more compact and small, and obviously possessing the characteristics of portability.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 13 As shown, a portable ice maker includes a housing 1. The housing 1 is equipped with a control device, a refrigeration device, and an ice removal device. The refrigeration device includes a compressor 2 electrically connected to the control device. The compressor 2 is connected in sequence along the main refrigerant pipe 21 to a condenser 3, a dryer 4, a capillary tube 5, and an ice-making evaporator 6.

[0033] The ice-making evaporator 6 includes at least a water injection box 61 made of metal, the water injection box 61 having a water storage cavity 601 inside, and a plurality of spaced ice-making mold columns 62 integrally connected to the water injection box 61 by sheet metal;

[0034] Furthermore, an ice tray 7 is detachably installed inside the water storage cavity 601. The ice tray 7 is provided with several partition structures for separating the inner cavity of the ice tray 7. An independent ice-making zone 701 is defined between two adjacent partition structures. The ice-making mold column 62 extends into the corresponding ice-making zone 701.

[0035] The bottom surface of the water injection box 61 is connected to a flow channel component. A mold column cavity 63 is provided between the flow channel component and the ice-making mold column 62. The end face of the flow channel component facing the water injection box 61 is recessed with a component groove 64. The flow channel component defines a refrigerant flow channel 65 connecting each mold column cavity 63 between the component groove 64 and the water injection box 61.

[0036] A liquid receiver 8 is also connected in series on the main refrigerant pipe 21 between the ice evaporator 6 and the compressor 2. The liquid receiver 8 has a refrigerant accommodating cavity 801 inside.

[0037] This ice maker uses a refrigerant containment cavity 801 to buffer the liquid refrigerant just discharged from the ice evaporator 6, thus expanding the capacity of the original compressor 2 compartment. This allows the refrigerant to circulate for a longer time in the main refrigerant pipe 21, increasing the heat exchange time between the liquid refrigerant and the ice evaporator 6, thereby improving ice-making efficiency.

[0038] The receiver 8 is provided with a refrigerant inlet 802 and a refrigerant outlet 803 communicating with the refrigerant accommodating cavity 801; wherein the refrigerant inlet 802 is arranged facing upward relative to the receiver 8, and the refrigerant outlet 803 is arranged facing downward relative to the receiver 8. The upper and lower parts of the compressor 2 are respectively provided with a refrigerant exhaust port 201 and a refrigerant return port 202; the receiver 8 is located within the height range between the refrigerant exhaust port 201 and the refrigerant return port 202; the height of the receiver 8 is level with that of the compressor 2, which can provide the most suitable buffer speed.

[0039] The liquid reservoir 8 includes a tank body 81 and a tank cover 82 sealed to the opening of the tank body 81. The refrigerant outlet 803 is located at the bottom of the tank body 81, and the refrigerant inlet 802 is located at the center of the tank cover 82. The refrigerant inlet 802, the refrigerant accommodating cavity 801, and the refrigerant outlet 803 are coaxially arranged on the liquid reservoir 8. This structure of the liquid reservoir 8 can form a large refrigerant accommodating cavity 801, making the buffer space for expansion and capacity increase larger.

[0040] In this embodiment, the can lid 82 is flared, and the diameter of the end of the can lid 82 near the refrigerant inlet 802 is smaller than the diameter of the end away from the refrigerant inlet 802. The end of the can lid 82 away from the refrigerant inlet 802 extends with a can lid edge 821. When the can lid 82 is placed on the can opening, the can lid edge 821 is nested on the outer wall of the can body 81. During production, the can lid 82 is welded to the can body 81 through the can lid edge 821, which can improve the connection strength and the sealing performance.

[0041] The partition structure includes a partition plate 71 vertically arranged inside the ice holder 7; the ice holder 7 has a concave plate structure, and the partition plates 71 extend upward from the bottom of the plate. One side of the partition plates 71 is connected to the side wall of the ice holder 7, and the other side forms an intermediate partition 702. The ice-making partitions 701 are interconnected through the intermediate partition 702. The intermediate partition 702 can evenly distribute drinking water into each ice-making partition 701, and based on the principle of communicating vessels, the remaining water level of each ice-making partition 701 is kept the same during the ice-making process.

[0042] Furthermore, the ice tray 7 is provided with a water inlet / outlet structure that connects to the inner cavity of the ice tray 7; specifically, the water inlet / outlet structure includes a water inlet / outlet 703 provided on the bottom of the tray, the water inlet / outlet 703 is correspondingly provided with the middle partition 702, and a ring convex ring 72 that separates the ice-making partition 701 and the middle partition 702 extends from the outer periphery of the water inlet / outlet 703;

[0043] This structure allows drinking water in the water storage chamber 601 to enter the inner cavity of the ice tray 7 through the inlet / outlet 703 and condense upon contact with the ice-making mold column 62 after the ice tray 7 is placed in the water storage chamber 601. When the ice particles are removed, the remaining drinking water in the inner cavity of the ice tray 7 can flow into the water storage chamber 601 through the inlet / outlet 703 to drain the ice particles.

[0044] The ice tray 7 is formed into a square, elliptical, circular, polygonal, or a combination thereof through the plate wall; the intermediate partition 702 is located at the center of the inner cavity of the ice tray 7, and several partition plates 71 are distributed radially along the outer periphery of the intermediate partition 702.

[0045] The plate wall is provided with a handle structure for taking out and putting in the ice tray 7; in this embodiment, the top edge of the side wall of the ice tray 7 extends outward with an outward flange 73, and a convex flange 74 extends on the opposite side of the outward flange 73. The two convex flanges 74 form a handle structure, which makes it convenient for the user to pick up the ice tray 7 by hand.

[0046] The bottom of the ice tray 7 is provided with several mold column through holes 704 for the ice-making mold column 62 to pass through. Each ice-making section 701 is provided with at least one mold column through hole 704. The ice-making mold column 62 is inserted into the inner cavity of the ice tray 7 through the mold column through hole 704.

[0047] The diameter of the through hole 704 is close to the diameter of the ice-making mold 62. When the drinking water in the inner cavity of the ice holder 7 comes into contact with the ice-making mold 62, it will condense into bullet-shaped ice particles. The diameter of the ice particles is larger than the diameter of the through hole 704. When the ice holder 7 is removed, the ice particles on each ice-making mold 62 can be lifted and removed from the ice-making mold 62, while ensuring that the ice particles will not fall from the through hole 704.

[0048] The ice-making mold column 62 is integrally stretched from the bottom wall of the water injection box 61 to form an open upper chamber 621. The component groove 64 includes several recessed cavities 641 and several connecting grooves 642. The recessed cavities 641 correspond one-to-one with the upper chamber 621 and together form the inner cavity 63 of the mold column. Adjacent recessed cavities 641 are connected by connecting grooves 642. The refrigerant enters the inner cavity 63 of the mold column through the main refrigerant pipe 21 and absorbs heat. The drinking water in the water injection box 61 contacts the surface of the ice-making mold column 62 and condenses into ice particles.

[0049] The flow channel component includes a metal base plate 66. The metal base plate 66 is formed with a component groove 64 by sheet metal process. Specifically, a circular protrusion 661 and a strip-shaped protrusion 662 protruding from the bottom surface of the metal base plate 66 are stamped out. The circular protrusion 661 defines a recessed cavity 641, and the strip-shaped protrusion 662 defines a through groove 642. The metal base plate 66 is welded to the bottom surface of the water injection box 61. The welding makes the metal base plate 66 firmly and reliably connected, and the sealing between the two is better.

[0050] Several ice-making mold columns 62 are arranged at equal intervals around the center periphery of the bottom wall of the water injection box 61. Correspondingly, several recessed cavities 641 and several interconnected grooves 642 are interlocked to form a closed-loop component groove 64. A refrigerant inlet pipe 67 and a refrigerant outlet pipe 68 extend from the flow channel component. The refrigerant inlet pipe 67 and the refrigerant outlet pipe 68 are respectively connected to the bottom of two adjacent recessed cavities 641.

[0051] The control device includes a rechargeable battery pack 91, a control box 92, and a control circuit board 93. A battery frame 94 is also connected to the housing 1 and is mounted on the outside. The battery frame 94 has a partition cavity 941 that separates it from the refrigeration unit. The rechargeable battery pack 91 is disposed within the partition cavity 941. The control box 92 is mounted and connected to the lower part of the battery frame 94 and is electrically connected to the compressor. The control circuit board 93 is mounted and connected to the back side of the battery frame 94. The battery frame 94 separates the rechargeable battery pack 91 from the refrigeration unit, providing insulation against heat and moisture. The addition of the rechargeable battery pack 91 allows the ice maker to be used outdoors. The rechargeable battery pack 91 provides DC power to meet the operating requirements of the rotary compressor 2.

[0052] The ice-making evaporator 6 is provided with a reinforcing support on the side facing the battery frame 94, and the battery frame 94 is provided with a corresponding reinforcing mating part that connects to the reinforcing support on the back side.

[0053] In this embodiment, the reinforcing support part includes a positioning clamp 601; the reinforcing mating part includes a positioning protrusion 942 that mates with the positioning clamp 601. The positioning protrusion 942 is inserted into the positioning clamp 601, so that the ice evaporator 6 and the battery frame 94 support and position each other.

[0054] The compressor 2 is connected to a compressor bracket 10, which has several circumferentially distributed support legs 111. The compressor 2 is securely connected to the housing 1 via these support legs 111, and elastic damping pads 11 are connected between the support legs 111 and the housing 1. The elastic damping pads 11 reduce the transmission of vibrations generated by the rotor compressor 2 during operation to the housing 1.

[0055] The compressor 2 is a rotary compressor 2; and the control device, condenser 3, dryer 4, capillary tube 5 and ice-making evaporator 6 are each arranged on the sides of the rotary compressor 2 in different directions. Specifically, the control device is arranged on the right side of the rotary compressor 2, the condenser 3 is arranged on the rear side of the rotary compressor 2, the dryer 4 and capillary tube 5 are arranged on the front side of the rotary compressor 2, the ice-making evaporator 6 is arranged directly above the rotary compressor 2, and the liquid receiver 8 is arranged on the left side of the rotary compressor 2.

[0056] Compared to existing technologies, this portable ice maker uses a rotary compressor 2, which has advantages such as small size. This reduces the space occupied by the compressor 2 inside the ice maker, thus reducing the size of the ice maker and making it easier to carry around. In addition, the rotary compressor 2 is driven by DC and has low energy consumption. Therefore, the power supply needs can be met by the built-in battery pack in the ice maker. Furthermore, the various refrigeration components are arranged in different positions around the rotary compressor 2, which can make reasonable use of the internal space of the ice maker, making the ice maker more compact and portable.

[0057] The condenser 3 is connected to the back side of the compressor 2 by a cooling fan 12, and the housing 1 has a cooling vent 101 at the air outlet of the cooling fan 12. The cooling fan 12 dissipates heat from the condenser 3, causing the gaseous refrigerant to cool down and be converted into liquid refrigerant. Since the condenser 3 is located on the rear side of the rotary compressor 2, it can also absorb the heat from the operation of the rotary compressor 2 and dissipate heat from the rotary compressor 2.

[0058] The dryer 4 is coaxially provided with an air inlet port 401 and an air outlet port 402. The air inlet port 401 is vertically downward relative to the dryer 4, and the air outlet port 402 is vertically upward relative to the dryer 4. The inner diameter of the capillary tube 5 is smaller than the inner diameter of the main refrigerant pipe 21, and the capillary tube 5 is spirally coiled next to the front side of the rotor compressor 2. The capillary tube 5 is mainly used for flow interception, replacing the large pipe of the original main refrigerant pipe 21 with a small pipe, and can extend the length of the capillary tube 5 in a narrow space, which helps to extend the refrigerant circulation time.

[0059] In addition, a handle 102 is rotatably connected to the housing 1, which facilitates the movement of the ice maker and improves its portability.

[0060] The de-icing device includes a hot refrigerant pipe 22 and a solenoid valve 13, the solenoid valve 13 being electrically connected to a control device; the two ends of the hot refrigerant pipe 22 are connected to the main refrigerant pipe 21 between the compressor 2 and the ice-making evaporator 6, and the solenoid valve 13 is connected in series with the hot refrigerant pipe 22 and controls the opening and closing of the hot refrigerant pipe 22; the de-icing device heats the ice particles, causing them to detach from the ice-making evaporator 6, making it easier to remove the ice.

[0061] During defrosting, solenoid valve 13 opens hot refrigerant pipe 22, and refrigerant discharged from rotor compressor 2 flows along main refrigerant pipe 21 and hot refrigerant pipe 22. The high-temperature and high-pressure refrigerant from rotor compressor 2 flows directly to ice evaporator 6 without passing through condenser 3 and capillary tube 5, thereby raising the temperature of ice evaporator 6. The surface of ice particles in contact with ice evaporator 6 melts, thus defrosting, and finally the ice particles are removed from ice evaporator 6.

[0062] The ice-making evaporator 6 also includes an evaporator shell 69, and the water injection box 61 is assembled and connected to the evaporator shell 69. The water injection box 61 is also provided with a heat-insulating material 610 covering the bottom surface of the water injection box 61 inside the shell. The heat-insulating material 610 keeps the water injection box 61 cold and can improve the ice-making efficiency.

[0063] The water injection box 61 and the ice-making mold column 62 are integrally made of the same metal material, which includes but is not limited to pure aluminum or aluminum alloy. The water injection box 61 and the ice-making mold column 62 are mainly made of pure aluminum or aluminum alloy material. Aluminum has excellent thermal conductivity and is suitable for heat conduction structures such as refrigeration and cooling.

[0064] The height of the water injection box 611 is H1, and the height of the ice-making mold column 62 is H2, where 1 / 2H1≤H2

[0065] The ice-making mold column 62 is bullet-shaped, and the diameter of the ice-making mold column 62 increases linearly from the top to the bottom. The bullet-shaped structure of the ice-making mold column 62 helps ice particles to detach from the ice-making mold column 62 when it thaws.

[0066] This embodiment is not limited thereto. The above describes the preferred embodiments of the present invention, illustrating and describing the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as defined by the appended claims and their equivalents.​
