[0002] In the prior art, an ice-making mold for making solid ice cubes has a plurality of mold cavities with the same opening direction, and the evaporator of the ice-making machine is attached to the outer bottom wall of the mold cavity of the ice-making mold. When the mold cavity is deeper, the copper tube of the evaporator transfers the cold energy through the outer bottom wall of the mold cavity to the water in the mold cavity at a slower rate, resulting in a long ice-making time.

[0003] In addition, when making solid ice cubes, considering the need for ice removal, the ice-making mold is placed vertically with the opening of the mold cavity facing horizontally, and then water circulates up and down through the mold cavity of the ice-making mold and maintains it for a certain period of time, so that multiple ice cubes can be formed on the ice-making mold.

[0031] Reference Figures 1 to 4 The utility model provides an ice-making device, comprising: an ice-making mold 100 and an air-conditioning system 200, wherein the ice-making mold 100 is provided with a plurality of mold cavities 110 with the same opening direction, the bottom wall of the mold cavity 110 constitutes a part of the bottom wall of the ice-making mold 100, and the outer peripheral wall of the mold cavity 110 constitutes a part of the outer peripheral wall of the ice-making mold 100, and the air-conditioning system 200 comprises a heat exchange tube group 210, and the heat exchange tube group 210 comprises a first tube section 211 abutting against the outer bottom wall of the ice-making mold 100 and a second tube section 212 abutting against the outer peripheral wall of the ice-making mold 100.

[0032] The ice-making device of the above structure utilizes the first pipe section 211 of the heat exchange tube group 210 to contact the outer bottom wall of the ice-making mold 100 to directly exchange heat with the bottom wall of the mold cavity 110, and utilizes the second pipe section 212 of the heat exchange tube group 210 to contact the outer peripheral wall of the ice-making mold 100 to directly exchange heat with the side wall of the mold cavity 110, thereby efficiently transferring cold energy to the water in the mold cavity 110 to quickly form ice cubes, thereby improving energy utilization efficiency, reducing electricity consumption, and improving ice-making efficiency.

[0033] See also Figure 3 and Figure 4In some embodiments of the utility model, the bottom wall of the ice-making mold 100 is a rectangular plate 101, and the contour edge of the rectangular plate 101 is provided with a surrounding plate 102 perpendicular to the rectangular plate 101, and the surrounding plate 102 is provided with a first partition 103 and a plurality of second partitions 104 spaced and orthogonal to the first partition 103, extending along its length direction, and the mold cavity 110 is defined between the first partition 103, the second partition 104 and the surrounding plate 102, and the plate thickness of the first partition 103, the second partition 104 and the surrounding plate 102 is substantially equal. The wall thickness of the ice-making mold 100 of the above structure is relatively thin, which is conducive to heat exchange, and the bottom and periphery of each mold cavity 110 can contact the heat exchange tube group 210, and the heat exchange efficiency is high.

[0034] See also Figure 3 and Figure 4 In some embodiments of the utility model, the first tube section 211 is a U-shaped tube, the side wall of the U-shaped tube is against the outer bottom surface of the rectangular plate 101, the length dimension of the U-shaped tube matches the length dimension of the rectangular plate 101, and the width dimension of the U-shaped tube matches the width dimension of the rectangular plate 101, that is, the U-shaped tube can be in contact with most of the area of ​​the entire rectangular plate 101, thereby improving the heat exchange uniformity of each mold cavity 110. The second tube section 212 includes a first side tube and a second side tube respectively connected to the two ends of the U-shaped tube through a curved tube section 213, the first side tube and the second side tube are clamped on the two long side plates of the enclosure 102, the first side tube is provided with a first bending section 214 at one end away from the curved tube section 213, and the second side tube is provided with a second bending section 215 at one end away from the curved tube section 213, the first bending section 214 and the second bending section 215 are close to each other, the first bending section 214, the second bending section 215 and the two curved tube sections 213 surround the four corners of the ice-making mold 100 to limit the movement of the ice-making mold 100. It can be understood that the first side tube and the second side tube are located above the U-shaped tube, and the curved tube section 213 surrounds two corner positions of the ice-making mold 100 from bottom to top, and the first bent section 214 and the second bent section 215 are close to each other to surround the other two corner positions of the ice-making mold 100, so that the first side tube and the second side tube can be tightly attached to the two long side panels of the enclosure 102, thereby improving the heat exchange performance, and also being able to limit the ice-making mold 100 to ensure that the ice-making mold 100 is not easily displaced when subjected to force.

[0035] See also Figure 1 and Figure 5In some embodiments of the present invention, the ice-making mold 100 is rotatably disposed on the ice-making machine body 400 via a horizontally placed pivot 300. The ice-making mold 100 can be rotated relative to the ice-making machine body 400 until the opening of the mold cavity 110 is upward, or rotated relative to the ice-making machine body 400 until the opening of the mold cavity 110 is facing in a direction for ice cubes to fall off. The heat exchange tube group 210 is connected to the pipeline of the air-conditioning system 200 via a hose 500, so that the heat exchange tube group 210 and the ice-making mold 100 can rotate around the pivot 300 together. Figure 1 When making ice, first rotate the ice-making mold 100 relative to the ice-making machine body 400 until the opening of the mold cavity 110 faces upward, and then fill the mold cavity 110 with water. Figure 5 After the heat exchange tube group 210 of the air conditioning system 200 cools the water in the mold cavity 110 into ice cubes, the ice-making mold 100 is rotated relative to the ice-making machine body 400 until the opening of the mold cavity 110 is horizontal, tilted downward, or facing downward so that the ice cubes can fall off. Since the heat exchange tube group 210 and the air conditioning system 200 are connected by a hose 500, the heat exchange tube group 210 and the ice-making mold 100 can rotate directly together, avoiding the use of circulating water to achieve ice making, and the produced ice cubes have a higher density, high ice making efficiency, and stable ice quality.

[0036] Specifically, see Figure 1 The air conditioning system 200 includes a compressor 220, a heat exchange assembly 230 and a throttling assembly 240. The output end of the compressor 220 is connected to an electric valve body capable of switching the refrigerant to first pass through the heat exchange tube group 210 or the heat exchange assembly 230. Generally speaking, in the ice-making working mode, the compressor 220, the heat exchange assembly 230, the throttling assembly 240 and the heat exchange tube group 210 are connected in sequence, and the heat exchange tube group 210 acts as an evaporator to transfer cold to water, thereby forming ice cubes; in the de-icing working mode, the compressor 220, the heat exchange tube group 210, the throttling assembly 240 and the heat exchange assembly 230 are connected in sequence, and the heat exchange tube group 210 acts as a condenser to transfer heat to ice cubes, thereby helping ice cubes to fall off from the opening of the mold cavity 110. Among them, the electric valve body adopts a four-way valve commonly used in the air conditioning system 200, which will not be further described here. The cooling and heating functions are integrated in the air conditioning system 200, and there is no need to configure a heater separately, which is very convenient to use. Furthermore, since the hose 500 is used to connect the heat exchange tube group 210 and the air conditioning system 200, the heat exchange tube group 210 keeps in contact with the ice making mold 100 when the ice making mold 100 rotates around the pivot 300, so that the heat exchange tube group 210 and the ice making mold 100 can exchange heat instantly.

[0037] See also Figure 2 and Figure 3In some embodiments of the present invention, a first shell 610 and a second shell 620 are further included. The first shell 610 has an open cavity. The ice-making mold 100 is installed in the cavity by bolts to drive the first pipe section 211 to press against the bottom wall of the cavity, that is, the first pipe section 211 is clamped and fixed by the ice-making mold 100 and the first shell 610, which is conducive to the full contact between the first pipe section 211 and the ice-making mold 100. The second shell 620 is provided with a through hole portion 621 connected to the opening of the mold cavity 110, and water can enter the mold cavity 110 from the through hole portion 621. 0, ice cubes can also be separated from the ice-making mold 100 from the through hole portion 621, the second shell 620 is installed on the first shell 610 to close the opening of the cavity, and the end of the whole composed of the first shell 610 and the second shell 620 is provided with a cylindrical tube portion, and the cylindrical tube portion constitutes the pivot 300. The input pipe end and the output pipe end of the heat exchange tube group 210 are respectively extended from the cylindrical tube portion to connect the hose 500. The above-mentioned cylindrical tube portion not only serves as the pivot 300, but also can be used for output at both ends of the heat exchange tube group 210. The structure is very simple and ingenious, and it plays the effect of one object serving two purposes.

[0038] See also Figure 1 , Figure 2 and Figure 5 In some embodiments of the utility model, a first semicircular tube sleeve 310 is formed at one end of the first shell 610, and a second semicircular tube sleeve 320 matched with the first semicircular tube sleeve 310 is provided at one end of the second shell 620. The first semicircular tube sleeve 310 and the second semicircular tube sleeve 320 are spliced ​​into the cylindrical tube portion. The ice-making mold 100 is provided with a first travel switch 710 and a second travel switch 720 arranged at intervals around the axial direction of the pivot 300. The first shell 610 and the second shell 620 are integrally connected to a driver 730 for driving the first travel switch 710 and the second travel switch 720 to rotate axially around the pivot 300. The driver 730, the first travel switch 710 and the second travel switch 720 are all connected to a control unit. An eccentric convex portion 330 capable of triggering the first travel switch 710 and the second travel switch 720 in sequence is formed on the first semicircular tube sleeve 310 or the second semicircular tube sleeve 320. It can be understood that when the driver 730 drives the cylindrical tube portion to rotate so that the opening of the mold cavity 110 is upward, the eccentric convex portion 330 triggers the first stroke switch 710, and the driver 730 stops immediately, thereby keeping the opening of the mold cavity 110 upward, and then the control unit calculates a certain period of time and drives the driver 730 to drive the cylindrical tube portion to rotate so that the opening direction of the mold cavity 110 can achieve ice removal. At this time, the eccentric convex portion 330 triggers the second stroke switch 720, and the driver 730 stops immediately to maintain the angular position of the ice-making mold 100; the above structure realizes the functions of automatic ice making and ice removal.

[0039] See also Figure 2 and Figure 3 In some embodiments of the present invention, a transmission sleeve 611 is formed at the other end of the first housing 610, the transmission sleeve 611 has a non-circular transmission hole 612, and the driver 730 has a non-circular transmission shaft 731 passing through the transmission hole 612. With the above structure, the driver 730 can be arranged at one end of the first housing 610, and the first travel switch 710 and the second travel switch 720 can be arranged at the other end of the first housing 610, which is conducive to structural design and reasonable layout, and convenient for production and manufacturing.

[0040] In some embodiments of the utility model, the hose 500 is a nylon tube, and the two ends of the nylon tube are respectively sealed and connected to the ends of the heat exchange tube group 210 and the pipeline of the air conditioning system 200. The nylon tube has good toughness and high strength, can meet the bending requirements, and has a long service life. Of course, in other embodiments, the hose 500 can also be a rubber tube.

[0041] See also Figure 6 In some embodiments of the utility model, a metal joint 810 is inserted into the end of the nylon tube, and a riveted tube 820 is provided on the outer sleeve of the nylon tube. The riveted tube 820 presses the tube wall of the nylon tube against the metal joint 810. The end of the metal joint 810 away from the nylon tube is welded to the end of the heat exchange tube group 210 or the pipeline of the air conditioning system 200, or the end of the metal joint 810 away from the nylon tube is threadedly connected to the end of the heat exchange tube group 210 or the pipeline of the air conditioning system 200. It should be noted that the metal joint 810 has a connecting channel inside, and the riveted tube 820 is composed of a thin-walled metal sleeve. The tube wall of the nylon tube can be clamped between the metal joint 810 and the riveted tube 820 by applying force to the riveted tube 820 with a clamp. In addition, the pipes of the heat exchange tube group 210 and the air conditioning system 200 are copper pipes. In order to achieve a sealed connection between the copper pipe and the metal joint 810, the copper pipe and the metal joint 810 can be connected by welding or threading.
