For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] Reference Figures 1 to 3 , or see Figure 4 and Figure 5The utility model discloses an ice-making device with a flip-type ice-removing function, comprising: a body 100; an ice-making mold 200, which is rotatably arranged on the body 100 via a horizontally arranged pivot 214, the ice-making mold 200 having a plurality of mold cavities 230 with the same opening direction, the ice-making mold 200 can be rotated relative to the body 100 until the opening of the mold cavity 230 is upward, or rotated relative to the body 100 until the opening of the mold cavity 230 is facing in a direction for ice cubes to fall off; a refrigeration system 300, which is arranged on the body 100, the refrigeration system 300 comprises a heat exchange coil 310 fixedly connected to the ice-making mold 200, and both ends of the heat exchange coil 310 are connected to the pipeline of the refrigeration system 300 via a hose 400, so that the heat exchange coil 310 and the ice-making mold 200 can rotate around the pivot 214 together.
[0031] When the ice making equipment with the above structure is making ice, refer to Figure 1 or Figure 4 First, the ice-making mold 200 is rotated relative to the machine body 100 until the opening of the mold cavity 230 is upward, and then the mold cavity 230 is filled with water. After the heat exchange coil 310 of the refrigeration system 300 cools the water in the mold cavity 230 into ice cubes, the ice-making mold 200 is rotated relative to the machine body 100 to Figure 2 The opening of the mold cavity 230 shown is oriented horizontally so that ice cubes can fall out. In this case, the mold cavity 230 is provided with an inclined surface that is conducive to the detachment of ice cubes, or the ice-making mold 200 is rotated relative to the machine body 100 to Figure 5 The opening of the mold cavity 230 is shown facing downward, and the ice cubes can fall off under the action of gravity. Since the heat exchange coil 310 and the refrigeration system 300 are connected by a hose 400, the heat exchange coil 310 and the ice-making mold 200 can rotate directly together. Compared with using circulating water to make ice, the ice-making equipment with a flip-type ice-breaking method of the utility model has a higher utilization rate of cold energy, a higher ice-making efficiency, and the quality of the ice cubes produced is more stable.
[0032] See also Figure 1 Or see Figure 4Specifically, the refrigeration system 300 further includes a compressor 320, a heat exchange assembly 330 and a throttling assembly 340, and the output end of the compressor 320 is connected to an electric valve body capable of switching the refrigerant to first pass through the heat exchange coil 310 or the heat exchange assembly 330. Generally speaking, in the ice-making working mode, the compressor 320, the heat exchange assembly 330, the throttling assembly 340 and the heat exchange coil 310 are connected in sequence, and the heat exchange coil 310 acts as an evaporator to transfer cold to water, thereby forming ice cubes; in the de-icing working mode, the compressor 320, the heat exchange coil 310, the throttling assembly 340 and the heat exchange assembly 330 are connected in sequence, and the heat exchange coil 310 acts as a condenser to transfer heat to ice cubes, thereby helping ice cubes to fall off from the opening of the mold cavity 230. Among them, the electric valve body adopts a four-way valve commonly used in the refrigeration system 300, which will not be further described here. The cooling and heating functions are integrated in the refrigeration system 300, and there is no need to configure a heater separately, which is very convenient to use. Furthermore, since the heat exchange coil 310 is connected to the refrigeration system 300 by the hose 400, the heat exchange coil 310 keeps contacting the ice making mold 200 when the ice making mold 200 rotates around the pivot 214, so that the heat exchange coil 310 and the ice making mold 200 can exchange heat instantly.
[0033] See also Figure 3 In some embodiments of the utility model, the ice-making mold 200 includes a shell assembly 210 and a heat exchange template, the pivot 214 is provided on the shell assembly 210, a plurality of the mold cavities 230 are formed on the heat exchange template, the shell assembly 210 has an installation cavity for accommodating the heat exchange coil 310 and the heat exchange template, and the shell assembly 210 is provided with a through hole portion 213 connected to the opening of the mold cavity 230. The installation cavity of the shell assembly 210 realizes the functions of installation, positioning and protection for the heat exchange coil 310 and the heat exchange template, and prevents the heat exchange coil 310 from accumulating dust. When the mold cavity 230 of the heat exchange template opens upward, the water injection mechanism of the ice-making device can inject water into the mold cavity 230 through the through hole portion 213. After ice making is completed, the ice cubes can also be separated from the heat exchange template from the position of the through hole portion 213.
[0034] See also Figures 1 to 3In some embodiments of the utility model, the pivot 214 is fixedly connected to the housing assembly 210, and a driver 800 for driving the pivot 214 to rotate is provided on the body 100. The body 100 is provided with a first travel switch 710 and a second travel switch 720 axially spaced around the pivot 214, and an eccentric protrusion 215 capable of triggering the first travel switch 710 and the second travel switch 720 in sequence is provided at the end of the pivot 214. The first travel switch 710, the second travel switch 720 and the driver 800 are all connected to a control unit. It can be understood that when the driver 800 drives the pivot 214 to rotate so that the opening of the mold cavity 230 is upward, the eccentric protrusion 215 triggers the first stroke switch 710, and the driver 800 stops immediately, thereby keeping the opening of the mold cavity 230 upward, and then the control unit calculates a certain period of time and drives the driver 800 to rotate the pivot 214 so that the opening direction of the mold cavity 230 can be de-iced. At this time, the eccentric protrusion 215 triggers the second stroke switch 720, and the driver 800 stops immediately to maintain the angular position of the heat exchange template; the above structure is used to achieve the functions of automatic ice making and de-icing.
[0035] See also Figure 1 and Figure 2 In some embodiments of the present invention, the hose 400 extends out along the side of the housing assembly 210 and is arranged around the pivot 214. It should be noted that the hose 400 bends during the rotation of the ice-making mold 200 around the pivot 214. The arrangement of the hose 400 extending out along the side of the housing assembly 210 and surrounding the pivot 214 is conducive to preventing the hose 400 from bending or twisting too much, and ensuring that the hose 400 can smoothly recover elastically.
[0036] See also Figure 3 In some embodiments of the utility model, the heat exchange template includes a rectangular bottom plate 221, and the rectangular bottom plate 221 is provided with a plurality of ice-making shells 222 extending upward along the surface of the rectangular bottom plate 221 at intervals along its length direction. The ice-making shell 222 includes at least one mold cavity 230, and a pipe-through passage 223 is defined between adjacent ice-making shells 222. The heat exchange coil 310 has a serpentine curved section sequentially penetrated through each of the pipe-through passages 223. In this embodiment, one ice-making shell 222 includes two mold cavities 230, and the diameter of the serpentine curved section is adapted to the width of the pipe-through passage 223, that is, the heat exchange coil 310 maintains contact with two adjacent ice-making shells 222 when penetrated through the pipe-through passage 223, thereby ensuring the heat conduction efficiency, which is conducive to accelerating the cooling of water into ice cubes.
[0037] See also Figure 3In some embodiments of the present utility model, in order to facilitate the installation and positioning of the heat exchange coil 310 and the heat exchange template, the shell assembly 210 includes a first shell 211 and a second shell 212, the first shell 211 has a sink with an opening, the heat exchange template is placed on the bottom wall of the sink, the through hole portion 213 is formed on the second shell 212, the second shell 212 covers the opening of the sink and the through hole portion 213 is sleeved on the contour edge of the ice-making shell 222, and the serpentine bending section is sandwiched between the first shell 211 and the second shell 212, so that the serpentine bending section restricts the heat exchange template from being separated from the shell assembly 210. In this embodiment, the first shell 211 and the second shell 212 are fastened by bolts, and the second shell 212 can enclose the above-mentioned installation cavity when covering the opening of the sink, and the second shell 212 can limit and fix the heat exchange template while pressing the serpentine bending section to the first shell 211, without the need to use an additional fixing structure to position the heat exchange template.
[0038] In some embodiments of the present invention, the hose 400 is a nylon tube, and the two ends of the nylon tube are respectively sealed and connected to the ends of the heat exchange coil 310 and the pipeline of the refrigeration system 300. 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 400 can also be a rubber tube.
[0039] See also Figure 6 In some embodiments of the utility model, a metal joint 500 is inserted into the end of the nylon tube, and a riveted tube 600 is provided on the outer sleeve of the nylon tube. The riveted tube 600 presses the tube wall of the nylon tube against the metal joint 500. The end of the metal joint 500 away from the nylon tube is welded to the end of the heat exchange coil 310 or the pipeline of the refrigeration system 300, or the end of the metal joint 500 away from the nylon tube is threadedly connected to the end of the heat exchange coil 310 or the pipeline of the refrigeration system 300. It should be noted that the metal joint 500 has a connecting channel inside, and the riveted tube 600 is composed of a thin-walled metal sleeve. The tube wall of the nylon tube can be clamped between the metal joint 500 and the riveted tube 600 by applying force to the riveted tube 600 with a clamp. In addition, the heat exchange coil 310 and the pipes of the refrigeration system 300 are copper pipes. In order to achieve a sealed connection between the copper pipe and the metal joint 500, the copper pipe and the metal joint 500 can be connected by welding or threading.
[0040] In some embodiments of the utility model, since the nylon tube is used to transmit the refrigerant, in order to ensure the heat insulation performance, the outer periphery of the nylon tube is provided with a heat insulation coating layer.
