Abstract
Description
Technical Field
[0001] This invention relates to the field of ice maker technology, and in particular to an ice maker that can automatically make cube-shaped ice blocks. Background Technology
[0002] Currently, ice produced by ice makers is mainly in the form of block ice and crescent-shaped ice. The ice boxes of ice makers for block ice are mostly made of plastic. The ice cubes are released by heating wires and twisting the ice box. This has the following disadvantages: 1. Because heating wires are required, the ice making speed is relatively slow; 2. Because block ice needs to be released from the ice maker by gravity, a large draft angle is required, resulting in uneven sizes at both ends, and it is not a true cube shape. Summary of the Invention
[0003] The purpose of this invention is to provide an ice maker that can automatically produce cube-shaped ice blocks, which can produce ice blocks in a true cube shape and can be quickly demolded, thereby improving ice-making efficiency.
[0004] To achieve the above objectives, the technical solution of the present invention is as follows: An ice maker capable of automatically producing cube-shaped ice blocks includes an ice-making box body rotatably mounted on a frame. The ice-making box body contains several compartments of the same size. A flipping device for driving the ice-making box body to rotate and an ejection device for ejecting ice blocks from the compartments are connected to the ice-making box body. The ejection device includes a movable plate vertically mounted on the bottom of the ice-making box body and a push plate slidably mounted on the inner wall of the compartments. Several push rods are mounted on the movable plate, and the push rods are inserted into the compartments and fixed to the bottom of the push plate. The push plate is in sealed contact with the inner wall of the compartments. A first driving device is provided on the ice-making box body to drive the movable plate closer to or further away from the bottom of the ice-making box body.
[0005] The flipping device includes a motor that is drivenly connected to the main body of the ice maker.
[0006] The ice-making box body has turntables fixedly installed at both ends by connecting rods. The turntables are rotatably installed within the frame, and the output shaft of the motor is fixedly connected to the axis of the turntables.
[0007] Each end of the ice-making box body is fixedly connected to a turntable via two connecting rods, and the first driving device is fixedly installed on the turntable.
[0008] The first driving device includes an electromagnet fixed on the moving plate and a permanent magnet fixed on the ice-making box body. By changing the energization of the electromagnet, the moving plate can slide up and down.
[0009] A sealing box is fixedly installed on the turntable, and a slider is slidably installed inside the sealing box. The slider is fixedly installed on the ice-making box body, the electromagnet is fixedly installed on the slider, and the permanent magnet is fixedly installed at the bottom of the sealing box.
[0010] The grid has a through hole at the bottom, through which the push rod passes to connect the moving plate and the push plate. The bottom of the push plate has a trapezoidal platform, and the inner wall of the through hole has an inclined wall that matches the inclined surface of the trapezoidal platform.
[0011] There are gaps between adjacent grids.
[0012] A pressure sensor is also provided between the electromagnet and the permanent magnet, and the pressure sensor and the electromagnet are electrically connected to the control board respectively.
[0013] After adopting the above technical solution, the beneficial effects of the present invention are: This invention discloses an ice maker capable of automatically producing cubic ice cubes. It includes an ice-making box body rotatably mounted on a frame. The ice-making box body contains several compartments of the same size. A flipping device for driving the ice-making box to rotate and an ejection device for ejecting ice cubes from the compartments are connected to the ice-making box body. The ejection device includes a movable plate vertically mounted on the bottom of the ice-making box body and a push plate slidably mounted on the inner wall of the compartments. Several push rods are mounted on the movable plate, inserted into the compartments and fixed to the bottom of the push plate. The push plate is in contact with and sealed against the inner wall of the compartments. A first driving device is provided on the ice-making box body to drive the movable plate closer to or further away from its bottom. By incorporating the flipping and ejection devices, after the ice cubes are frozen, they are flipped by the flipping device and then ejected by the ejection device. This achieves demolding of the ice cubes without the need for heating wires or creating a draft angle within the compartments, improving ice-making efficiency. Furthermore, the ice cubes are cubic in shape, resulting in a more aesthetically pleasing appearance.
[0014] The flipping device includes a motor that is connected to the main body of the ice container. The motor drives the rotation, which reduces the space required for movement and thus makes the overall size of the device smaller. At the same time, using a motor can minimize noise.
[0015] Turntables are fixedly installed at both ends of the ice maker body via connecting rods. The turntables are rotatably installed within the frame, and the output shaft of the motor is fixedly connected to the axis of the turntables. The turntables are fixed at each end of the ice maker body via two connecting rods. The first drive device is fixedly installed on the turntables, thereby improving its balance and making it less likely to tilt due to an unstable center of gravity, which would cause the ice cubes inside the ice maker to have irregular shapes.
[0016] The first driving device includes an electromagnet fixed on the moving plate and a permanent magnet fixed on the ice maker body. By changing the energization of the electromagnet, the moving plate can slide up and down. The electromagnetic control is more stable and will not be affected by the low temperature inside the ice maker body. It is more controllable and occupies less space.
[0017] By setting up a sealed box, the electromagnet and permanent magnet are protected, ensuring that the power supply is maintained.
[0018] The grid has a through hole at the bottom, through which a push rod passes to connect a moving plate and a push plate. The bottom of the push plate has a trapezoidal platform, and the inner wall of the through hole has an inclined wall that matches the inclined surface of the trapezoidal platform. This makes the push plate and the grid more airtight and prevents water leakage at the bottom of the grid.
[0019] By creating gaps between adjacent cells, the amount of water in each cell is kept consistent, ensuring that the ice blocks are the same size.
[0020] A pressure sensor is positioned between the electromagnet and the permanent magnet. The pressure sensor signal is connected to the control board, and the control board signal is connected to the electromagnet. If individual ice blocks adhere to the inner wall of the grid, preventing them from detaching, the electromagnet and permanent magnet will not be in contact. In this case, the pressure sensor will not detect pressure and will send a signal back to the control board. The control board will then provide a reverse current to the electromagnet, generating a repulsive force that pushes the electromagnet and permanent magnet upwards. The control board then controls the electromagnet to generate an attractive force. Under the combined effects of gravity and attraction, the electromagnet drives a pusher plate downwards, impacting the remaining ice blocks. This process repeats until all the ice blocks are detached.
[0021] This invention provides an ice maker that can automatically produce cube-shaped ice blocks, solving the technical problems of low ice-making efficiency and inability to produce perfectly cube-shaped ice blocks in the prior art. By setting up a flipping device and an ejection device, the ice blocks are flipped by the flipping device after freezing and then ejected by the ejection device. This achieves ice block demolding without the need for heating wires or creating a demolding slope in the grid, improving ice-making efficiency and producing cube-shaped ice blocks with a more aesthetically pleasing appearance.

Detailed Implementation
[0024] The invention will now be further described with reference to the accompanying drawings.
[0025] The orientations mentioned in this specification are based on the orientation of the ice maker that can automatically make cube ice blocks during normal operation, and do not limit the orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.
[0026] like Figure 1 As shown, an ice maker capable of automatically making cube-shaped ice blocks includes an ice-making container body 2 rotatably mounted on a frame 1. The ice-making container body 2 has several identically sized compartments 20, with gaps 201 between adjacent compartments 20. A flipping device 3 for driving its rotation and an ejection device 4 for ejecting ice blocks from the compartments 20 are connected to the ice-making container body 2. The ice-making container body 2 is made of metal, such as stainless steel, which has good heat conduction properties, improving ice-making efficiency.
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, rotating shafts 21 are fixed at both ends of the ice maker body 2. The rotating shafts 21 are rotatably mounted on the frame 1, thus enabling the ice maker body 2 to be rotatably mounted on the frame 1. The flipping device 3 drives the ice maker body 2 to flip 180°, so that the upper opening of the compartment 20 faces downward, allowing the frozen ice cubes in the compartment 20 to fall out. The flipping device 3 can adopt various structural forms. For example, the flipping device 3 can adopt a gear and rack structure, such as a gear fixed on the rotating shaft 21 and a rack slidably mounted on the frame 1. The rack is pushed back and forth by a cylinder or electric push rod, thereby controlling the gear to rotate forward or backward, thus realizing the flipping of the flipping device 3. In this embodiment, the flipping device 3 includes a motor 31 fixed on the outside of the frame 1. The output shaft of the motor 31 is connected to the rotating shaft 21. By rotating the motor 31 180°, the rotating shaft 21 is rotated 180°, thereby realizing the flipping of the ice maker body 2 180°.
[0028] To improve the stability of the ice maker body 2, turntables 211 are fixedly mounted at both ends of the ice maker body 2 via connecting rods 22, and a rotating shaft 21 is fixedly mounted on the axis of the turntables 211. Two connecting rods 22 are provided at each end, located on both sides of the ice maker body 2 respectively.
[0029] like Figure 2 As shown, the ejector device 4 includes a movable plate 41 that is vertically mounted on the bottom of the ice-making container body 2 and a push plate 42 that is slidably mounted on the inner wall of the grid 20. The push plate 42 is in sealed contact with the inner wall of the grid 20 and can slide up and down along the inner wall of the grid 20. The movable plate 41 is provided with several push rods 43. The bottom of the grid 20 is provided with a through hole 202. The push rods 43 are inserted into the grid 20 through the bottom through hole 202 and fixed to the bottom of the push plate 42. The bottom of the push plate 42 is provided with a trapezoidal platform 421. The inner wall of the through hole 202 is provided with an inclined wall that matches the inclined surface of the trapezoidal platform 421. By matching the inclined surface of the trapezoidal platform 421 with the inclined wall, the through hole 202 is sealed more tightly, preventing leakage.
[0030] The ice box body 2 is provided with a first driving device that drives the moving plate 41 to approach or move away from its bottom. The first driving device is fixedly installed on the turntable 211.
[0031] A sealing box 44 is fixedly installed on the turntable 211. A slide rail 441 is provided on the inner wall of the sealing box 44, and a slider is slidably installed within the slide rail 441. The two ends of the movable plate 41 are fixedly connected to the slider via support rods 45. To achieve obstacle avoidance, a slotted hole is provided at the front end of the sealing box 44, allowing the support rods 45 to slide up and down through the slotted hole. By setting up the slider and the slide rail 441, the movable plate 41 is slidably and limitedly installed at the bottom of the ice-making container body 2.
[0032] The first driving device includes an electromagnet 46 mounted on the slider and a permanent magnet 47 fixed to the bottom of the sealed box 44. By changing the energization of the electromagnet 46, such as energizing or de-energizing or changing the direction of the current, the electromagnet 46 and the permanent magnet 47 can be attracted or repelled, thereby controlling the slider to slide up and down, and thus controlling the moving plate 41 to move closer to or away from the bottom of the ice box body 2.
[0033] A pressure sensor 48 is installed between the electromagnet 46 and the permanent magnet 47. The pressure sensor 48 is connected to the control board, and the control board is connected to the electromagnet 46. If individual ice blocks stick to the inner wall of the grid 20, preventing them from being removed, the electromagnet 46 and the permanent magnet 47 will not be in contact. In this case, the pressure sensor 48 will not detect pressure and will send a signal back to the control board. The control board will then supply a reverse current to the electromagnet 46 to generate a repulsive force, pushing the electromagnet 46 and the permanent magnet 47 upward. At this point, the control board will then control the electromagnet 46 to supply current again to generate an attractive force. Under the action of gravity and attractive force, the electromagnet 46 will drive the push plate 42 to move downward, thereby impacting the ice blocks that have not yet been removed. This process will continue until all the ice blocks are removed.
[0034] like Figure 1 , Figure 2 and Figure 3 As shown in the diagram, the workflow of an ice maker that can automatically produce cube-shaped ice blocks is as follows: Initially, the opening of grid 20 faces upwards. Electromagnet 46 is energized and repels permanent magnet 47, or is de-energized. Under the action of gravity or repulsive force, push plate 42 is located at the bottom of grid 20 and contacts and seals with the inner wall of grid 20. A certain amount of water is injected into grid 20. Under the influence of notch 201, the amount of water in all grids is the same, and then freezing is performed. After freezing, motor 31 rotates 180°, realizing that rotating shaft 21 rotates 180°, thereby realizing that the ice box body 2 flips 180°. At this time, electromagnet 46 is energized and attracts permanent magnet 47, realizing that moving plate 41 moves downwards, and push plate 42 moves towards the opening of grid 20, thereby pushing out the ice block in grid 20 and realizing demolding. After pushing out, electromagnet 46 is de-energized or energized and repels permanent magnet 47. Push plate 42 returns to the bottom of grid 20, and motor continues to rotate or rotates 180° in the opposite direction, so that the opening of grid 20 continues to face upwards, and the ice-making process starts again.
[0035] This invention provides an ice maker that can automatically produce cube-shaped ice blocks, solving the technical problems of low ice-making efficiency and inability to produce perfectly cube-shaped ice blocks in the prior art. By setting up a flipping device and an ejection device, the ice blocks are flipped by the flipping device after freezing and then ejected by the ejection device. The ejection device removes the ice blocks, thus eliminating the need for heating wires and improving ice-making efficiency. The ejection device also enables the demolding of cube-shaped ice blocks without the need for a demolding slope, resulting in a more aesthetically pleasing appearance.
[0036] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
