[0002] The evaporator tube of the existing ice-making device is generally inserted into the through hole of the semicircular groove of the double-layer ice-making trough, which requires welding the evaporator tube with an elbow, making the processing difficult and inefficient. At the same time, when the evaporator tube is inserted into the through hole, only half of the surface area of ​​the evaporator tube is in contact with the ice-making trough to conduct cooling, resulting in low cooling efficiency. Summary of the Invention

[0004] In order to solve the above technical problems, the technical solution of the present invention is:

[0006] Furthermore, the upper end surface and / or the lower end surface is an arc surface, the notch cross section of the double-layer ice-making groove is formed by closing two arcs, and the evaporation tube is in close contact with the arc surface of the ice-making groove.

[0007] Furthermore, the evaporator tube is formed by bending a straight tube, and then the formed evaporator tube is flattened. The cross section of the flattened evaporator tube is flattened from a circular shape to an approximately elliptical shape. The flattened evaporator tube is inserted into the notch of the double-layer ice making groove, and the evaporator tube is expanded so that the evaporator tube and the notch are in full and close contact, ensuring that the cold amount transferred during refrigeration is conducted at a higher rate, thereby forming a higher heat transfer efficiency.

[0008] Furthermore, the inlet section and the outlet section of the evaporator tube are arranged at the bottom of the double-layer ice-making trough, and the double-layer ice-making trough is defined as a symmetrically arranged left ice-making trough arc and a right ice-making trough arc along the longitudinal axis of the double-layer ice-making trough. The middle section of the evaporator tube is first arranged on the left ice-making trough arc of the double-layer ice-making trough, and then arranged on the right ice-making trough arc of the double-layer ice-making trough.

[0009] Furthermore, the inlet section of the evaporator tube and the outlet section of the evaporator tube are closely arranged, so that there are more than two sections of evaporator tubes closely arranged in the central area of ​​the bottom of the ice-making trough, ensuring that the temperature in the central area of ​​the bottom of the double-layer ice-making trough is the lowest, thereby enhancing the ice-making capacity of the deepest part of the ice-making trough.

[0010] Furthermore, the ice-making partition divides the double-layer ice-making groove into a plurality of ice-cube-shaped areas; the ice-making partition is formed by two ice-making partitions connected in parallel.

[0012] Furthermore, the panel and base are both integral injection-molded structures, with a hollowed-out area in the middle of the panel exposing the ice-making partition to the air for easy water injection and ice making; fine grooves are provided on the surface around the panel to facilitate the passage of the ice-making partition.

DETAILED DESCRIPTION

[0024] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0025] See Figure 1-Figure 5 As shown, the present invention discloses an ice-making device, including a panel 1, a double-layer ice-making trough 2, an evaporation tube 3, a base 4, and an ice-making partition 5; the cross-section of the double-layer ice-making trough 2 is composed of two parallel closed arcs, the evaporation tube 3 is installed in the notch of the double-layer ice-making trough, the double-layer ice-making trough 2 equipped with the evaporation tube 3 is installed on the base 4, the ice-making partition 5 and the base 4 are connected with screws, and the corresponding arc segment of the ice-making partition 5 clamps the end arc of the double-layer ice-making trough 2. After the double-layer ice-making trough 2 is subjected to force, the bottom arc segment of the double-layer ice-making trough is correspondingly clamped in the notch of the base 4, so that the double-layer ice-making trough 2 and the base 4 are pressed tightly; then the panel 1 is installed on the nut support column of the base 4 and fastened with screws to form the entire ice-making device.

[0026] The evaporator tube 3 is formed by bending a straight tube and then flattening the formed evaporator tube 3. After flattening, the cross-section of the evaporator tube is flattened from a circular shape to a nearly elliptical shape 33. The flattened evaporator tube 3 is inserted into the notch of the double-layer ice making groove 2. The evaporator tube 3 assembled into the notch is then subjected to an expansion treatment to ensure that the evaporator tube 3 is in full and close contact with the inner surface of the notch, thereby more than doubling the cooling area and achieving higher heat transfer efficiency.

[0027] The inlet section 31 of the evaporator tube 3 is arranged at the bottom of the double-layer ice-making groove 2. The evaporator tube is first arranged on a half-arc surface of the double-layer ice-making groove and then on the other half-arc surface of the double-layer ice-making groove 2. The outlet section 32 of the evaporator tube is also arranged at the bottom of the double-layer ice-making groove and is closely arranged with the inlet section 31 of the evaporator tube. This ensures that more than two sections of evaporator tubes are closely arranged in the central area of ​​the bottom of the ice-making groove 2, ensuring that the temperature in the central area of ​​the bottom of the double-layer ice-making groove 2 is the lowest, thereby enhancing the ice-making capacity of the deepest part of the ice-making groove.

[0028] Several ice partitions 5 are arranged within the ice trough 2, dividing the trough 2 into several ice-cube-shaped areas. Each ice partition 5 is composed of two ice partitions 51 connected in parallel. A notch 52 is defined in the center of each ice partition 51 to facilitate the passage of ice water, ensuring a consistent ice water level across the partitions. Screw holes are provided at the junction of the two ice partitions 51, which secure the ice partition 5 to the base 4. The arcs on the ice partitions 5 secure the double-layered ice trough, integrating the double-layered ice trough, ice partitions, and base.

[0029] The panel 1 and the base 4 are both integral injection-molded structures. The middle part of the panel 1 is a hollowed-out area 12, which exposes the ice-making partition to the air and facilitates water injection and ice making. Baffles 13 are provided on both sides of the panel 1 to support and seal the ice-making partitions 51 on both sides. Fine grooves 11 are provided on the surface around the panel to avoid the ice-making partition 5 when assembling the panel 1. The panel 1 is tightly fastened to the base 4, and the two are tightly connected with screws.

[0030] The double-layer ice-making trough 2 is made of extruded profiles, and the ice-making partition 5 is made of metal stamping or integral injection molding. The ice-making partition material uses stainless steel or food-grade plastic with high hardness and toughness, and has the characteristics of corrosion resistance, antibacterial and easy cleaning.

[0031] During compressor cooling, the high-temperature, high-pressure refrigerant from the compressor passes through the expansion valve or capillary tube, then evaporates at low pressure within the evaporator tube, absorbing heat and starting to cool the air. Evaporator tube 3 cools the water within the double-layered ice trough. Because the evaporator tube expands tightly within the notch of the double-layered ice trough, the close contact between the evaporator tube and the arc-shaped surface of the notch ensures high heat transfer efficiency, quickly freezing the water. At this point, the water volume is highest at the bottom centerline of the trough. Therefore, two sections of evaporator tubes run side by side in the center of the bottom of the double-layered ice trough 2, maximizing cooling capacity in this area and ensuring the lowest temperature in the center of the bottom of the double-layered ice trough 2. When ice freezes to a certain degree, meeting the set requirements, the de-icing sensor sends a signal, and the high-temperature, high-pressure steam from the compressor's high-pressure pipeline flows directly through the reversing valve into the evaporator tube 3, heating the walls of the double-layered ice trough 2. After a certain period of heating, ice cubes automatically fall off.

[0032] The double-layer ice-making trough 2 is divided into ice grids evenly arranged by an ice-making partition 5. The ice-making partition 5 is composed of two ice-making partitions 51 connected in parallel. The notch of the ice-making partition 51 is V-shaped. The function of the V-shaped notch is to reduce the resistance of ice cubes to demolding. The shape of the notch makes the contact area between the ice cubes and the trough wall relatively small, which significantly reduces the friction of the ice cubes during the demolding process, guides the direction of demolding, reduces the probability of ice cube breakage, guides water to spread evenly in the double-layer ice-making trough, and reduces the accumulation of bubbles, thereby improving ice making efficiency.

[0033] The double-layer ice-making trough 2 is made of extruded profiles, and the ice-making partition 51 is made of metal stamping or integral injection molding. The material of the ice-making partition 51 is stainless steel or food-grade plastic with relatively high hardness and toughness.

[0034] A method for preparing an ice-making device comprises the following steps:

[0035] S1) Pre-treating the profile blank, and extruding the blank into a double-layer ice making trough 2 through an extrusion die;

[0036] S2) placing the extruded blank into a CNC machine to mill the double-layer ice trough;

[0037] S3) bending the evaporation tube 3 into a shape, and then flattening the evaporation tube into a substantially elliptical shape;

[0038] S4) inserting the evaporation tube 3 into the notch of the double-layer ice making groove 2 and tightening the evaporation tube 3 so that the evaporation tube and the arc surface of the double-layer ice making groove 2 are in close contact;

[0039] S5) processing the ice-making partition 51 into a shape with a notch 52, and then forming it into an ice-making partition 5;

[0040] S6) Place the double-layer ice trough 2 on the base 4, place the ice partition 51 on the double-layer ice trough to lock the double-layer ice trough arc, and fasten the ice partition 51 to the screw holes of the base 4 with screws. Then place the panel 1 on the screw support of the base 4, and fix the panel 1 and the base 4 with screws.

[0041] The above describes the embodiments of the present invention in detail in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments without departing from the principles and spirit of the present invention are still within the scope of protection of the present invention.
