Description

Technical Field

[0001] The utility model belongs to the technical field of ice making machines, in particular to a spray system for ice making machines. Background Art

[0002] Ice makers are a common type of ice-making equipment that can convert water or other liquids into solid ice cubes through a refrigeration system. Ice makers are widely used in many industries, including but not limited to food processing, frozen food processing, ice cream manufacturing, beverage production, etc. The spray system is a crucial component of the ice maker, which can spray liquid evenly toward the ice box.

[0003] In the Chinese utility model patent with publication number CN216432186U, an energy-saving water circulation spray device for an ice maker is disclosed. The water in the water tank is transported to the spray pipe through the water delivery component, and sprayed to the ice box through the spray hole to make ice. The excess water in the ice box falls into the water storage tank under the action of gravity. When the amount of water in the water storage tank is too much, the floating ball is pushed upward by the buoyancy. The floating ball pushes the sealing component to seal the delivery component, thereby automatically adjusting the water delivery amount of the water delivery component. It is not necessary to use a controller and a valve to control the water amount, which is more energy-saving, easy to operate, and has a long service life.

[0004] However, in the actual use of the ice maker, the spray head in the ice maker needs to be regularly disassembled and cleaned to remove impurities contained therein, and it needs to be replaced in time when damaged. However, the above technical solution still lacks a positioning structure that facilitates the quick disassembly and assembly of the spray head, resulting in inconvenience and slow speed in the process of disassembly, cleaning or replacement of the spray head, which affects the maintenance of the machine. Therefore, it is urgent to improve the existing spray system for ice makers and provide a spray system for ice makers with easy disassembly and assembly of the spray head. Utility Model Content

[0025] The embodiments described below are only some of the embodiments of the present invention and do not represent all the embodiments consistent with the present invention. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:

[0026] like Figure 1-5 As shown, the utility model ice maker spray system comprises an ice maker inner wall 1 and an ice box 2, the ice box 2 and a water dividing plate 3 are fixedly connected to the ice maker inner wall 1, the water dividing plate 3 is located above the ice box 2, a water supply pipe 4 is fixedly connected to the water inlet at the right end of the water dividing plate 3, the left and right ends of the water dividing plate 3 are internally connected with mounting pipes 5 with bearings, the top outer sides of the two mounting pipes 5 are fixedly sleeved with worm gears 9, a lifting and positioning assembly 6 is provided between the ice box 2 and the water dividing plate 3, and a plurality of spraying groups are equidistantly installed on the inner side of the lifting and positioning assembly 6 in the horizontal direction.

[0027] Based on the above structure, the lifting and positioning assembly 6 includes a bracket 61, a screw 62, a groove 63 and a fixing column 64. Screws 62 are fixed above the left and right ends of the bracket 61. A plurality of grooves 63 are provided on the inner side of the front end of the bracket 61 at equal intervals along its length direction. Fixing columns 64 are symmetrically provided on the left and right sides of each groove 63. The fixing columns 64 are fixedly connected to the upper end surface of the bracket 61.

[0028] In this embodiment, since the screw 62 is threadedly connected to the mounting tube 5, when the two mounting tubes 5 rotate synchronously in the same direction, the two screws 62 can be controlled to drive the bracket 61 and multiple groups of spray assemblies 7 to move vertically downward, so that the spray assemblies 7 can be disassembled, cleaned or replaced.

[0029] On the basis of the above structure, the two screw rods 62 are respectively threadedly connected to the two mounting pipes 5 , and the plurality of grooves 63 are arranged in a one-to-one correspondence with the plurality of spray components 7 .

[0030] In this embodiment, the groove 63 is provided to facilitate the clamping installation of the spray assembly 7 on the inner side of the bracket 61 .

[0031] On the basis of the above structure, the spray assembly 7 includes a spray head 71, a hose 72, a sealing ring 73 and a ejector pin 74. The spray head 71 is snap-fitted on the inner side of the groove 63. The bottom end of the spray head 71 is bonded with the hose 72, the top inner wall of the spray head 71 is bonded with the sealing ring 73, and the middle inner wall of the spray head 71 is fixedly connected with an ejector pin 74 with an "L"-shaped longitudinal section.

[0032] In this embodiment, water is conveniently transported to the ice-making box 2 for spraying and making ice through one end of the hose 72, and the sealing ring 73 is provided to improve the sealing between the spray head 71 and the water outlet 81.

[0033] On the basis of the above structure, hole structures compatible with the fixing column 64 are opened at the bottom of the left and right ends of the spray head 71, the intersection surface of the spray head 71 and the water outlet 81 is inclined, and a through hole compatible with the hose 72 is opened inside the top of the ice box 2.

[0034] In this embodiment, the hole structure at the bottom of the spray head 71 facilitates the insertion and positioning of the spray head 71 and the fixing column 64, and facilitates the bracket 61 to drive the spray head 71 to rise and fall stably, thereby achieving stable docking between the spray head 71 and the water outlet 81.

[0035] On the basis of the above structure, the ball head rod 82 forms an elastic structure through the spring 84. After the spray assembly 7 is disassembled, the bottom of the ball head rod 82 can contact and seal with the water outlet 81.

[0036] In this embodiment, when the spray head 71 is separated from the water outlet 81, the ball head rod 82 that loses the extrusion can be moved downward by the spring 84, which can achieve the resistance seal of the water outlet 81, avoid water leakage after the spray head 71 is disassembled, and make the water outlet 81 have the function of automatic closing.

[0037] The working principle of the utility model is as follows:

[0038] When in use, water is supplied to the water distribution plate 3 through the water supply pipe 4 connected to the external water source, and the water can enter the ice making box 2 through the multiple water outlets 81 at the bottom of the water distribution plate 3, the spray head 71 and the hose 72, and the spray ice making work begins. When the spray head 71 needs to be cleaned or replaced, the working state of the ice maker is first turned off, and then the servo motor 10 is started to control the rotation of the worm 11, and the two worm gears 9 are used to drive the left and right mounting tubes 5 to rotate synchronously in the same direction. Since the mounting tubes 5 are threadedly connected to the screw 62, when the two mounting tubes 5 rotate, the two screws 62 can be controlled to drive the bracket 61 and The multiple groups of spray assemblies 7 are synchronously moved downward, so that the multiple spray heads 71 ​​can be moved downward and separated from the corresponding water outlets 81. Then, the spray heads 71 ​​can be removed from the bracket 61 and cleaned or replaced. The disassembly is quick and the operation is convenient. When the spray heads 71 ​​are installed, the fixing columns 64 above the bracket 61 are used to facilitate the preliminary positioning of the spray heads 71. When the bracket 61 pushes the spray heads 71 ​​upward, the inclined interface between the spray heads 71 ​​and the water outlets 81 can strongly squeeze the sealing rings 73, thereby improving the sealing between the spray heads 71 ​​and the water outlets 81 when they are installed, and avoiding liquid leakage.

[0039] When the sprinkler head 71 is controlled to move downward and separate from the water outlet 81 for disassembly, the ball head rod 82 that has lost the squeezing of the ejector pin 74 can be stably moved downward by the spring 84 under the limiting action of the sleeve 83, and the ball head part at the bottom end of the ball head rod 82 can achieve a resistance seal on the water outlet 81, which is convenient for automatically closing the water outlet 81 and avoiding water leakage at the water outlet 81 after the sprinkler head 71 is disassembled. When the sprinkler head 71 is subsequently installed, the ejector pin 74 can push the ball head rod 82 upward again to ensure that the water flow path is unobstructed.
