Example 1
Referring to fig. 1 to 4, the present invention provides an ice cubes transferring apparatus, which includes an ice bank 1, a lifting driving unit, and a skating unit 6 disposed outside the ice bank 1; an ice feeding port is formed on the side wall of the ice storage box 1; the top surface of the ice sliding unit 6 is used for bearing ice cubes, and the top surface of the ice sliding unit 6 is downwards inclined and extends to the ice storage box 1 from one end, far away from the ice storage box 1, of the top surface; the lifting drive unit is connected to the ice skating unit 6, and is configured to drive the ice skating unit 6 to move up and down so that the ice skating unit 6 located below the ice conveying opening conveys the ice cubes carried by the ice skating unit up to the ice conveying opening. Further, the device also comprises a turnover door 2, a driving rod 3 and a movable shaft seat 5, wherein the turnover door 2 is used for opening and closing an ice feeding port, and the turnover door 2 is rotatably connected to the ice storage box 1 through a rotating shaft; the lifting driving unit is connected with the skating unit 6 through a movable shaft seat 5, the top surface of the movable shaft seat 5 is an inclined surface from top to bottom, the top end of the driving rod 3 is connected with the rotating shaft, and the bottom end of the driving rod abuts against the top surface of the movable shaft seat 5.
When ice is taken out, the lifting driving unit is started to drive the movable shaft seat 5 to move upwards. Since the skating unit 6 is connected to the movable shaft seat 5, the skating unit 6 and the movable shaft seat 5 move synchronously, and the skating unit 6 moves together when the movable shaft seat 5 moves upwards. In addition, in the process of moving the movable shaft seat 5 upwards, the bottom end of the driving rod 3 slides downwards along the top surface of the movable shaft seat 5, that is, the bottom end of the driving rod 3 rotates around the top end thereof under the pushing of the top surface of the movable shaft seat 5, and then the turnover door 2 is driven to be opened gradually. Specifically, if the top surface of the movable shaft seat 5 is inclined downward, the driving rod 3 rotates clockwise and the turnover door 2 is gradually opened inward as the movable shaft seat 5 continuously rises; if the top surface of the movable shaft seat 5 inclines upwards, the driving rod 3 rotates anticlockwise and the turnover door 2 is gradually opened outwards along with the continuous rising of the movable shaft seat 5. Since the top surface of the ice skating unit 6 is downwardly inclined from one end thereof, which is far away from the ice bank 1, to the ice bank 1, when the ice skating unit 6 is raised to the ice feeding port, the ice cubes on the ice skating unit 6 slide into the ice bank 1 through the ice feeding port along the top surface of the ice skating unit 6 by its own weight.
And when the ice is taken out, the lifting driving unit is started to drive the movable shaft seat 5 to move downwards. At this time, the skating unit 6 moves downward together therewith. And, in the process of moving the moving shaft seat 5 downward, the bottom end of the driving rod 3 will slide upward along the top surface of the moving shaft seat 5. Specifically, if the top surface of the movable shaft seat 5 is inclined downward, the driving rod 3 rotates counterclockwise and the turnover door 2 is gradually closed outward as the movable shaft seat 5 is continuously lowered; if the top surface of the movable shaft seat 5 inclines upwards, the driving rod 3 rotates clockwise and the turnover door 2 is gradually closed inwards along with the continuous rising of the movable shaft seat 5.
Therefore, the device has a simple structure and is convenient to operate, the moving shaft seat 5 and the skating unit 6 move synchronously, and when the lifting driving unit drives the moving shaft seat 5 to move upwards or downwards, the skating unit 6 moves together with the moving shaft seat. Because the top end of the driving rod 3 is connected with the rotating shaft of the turnover door 2, the bottom end of the driving rod abuts against the top surface of the movable shaft seat 5, and the top surface of the movable shaft seat 5 is an inclined surface from top to bottom, the linear movement of the movable shaft seat 5 can drive the driving rod 3 to rotate under the action of the top surface of the movable shaft seat, and the driving rod 3 can drive the turnover door 2 to gradually open or close the ice feeding port in the rotating process. Along with the turning door 2 gradually opens the ice feeding port, the ice sliding unit 6 gradually approaches the ice feeding port, and then when the ice sliding unit 6 moves to the ice feeding port, ice cubes carried on the ice sliding unit 6 slide into the ice storage box 1 through the ice feeding port by means of self gravity. Therefore, the device can not only transfer ice blocks from a low point to a high point in a limited space, but also has the advantages of large quantity of ice blocks output at a single time, low noise, high transportation efficiency and high reliability. In addition, the ice maker can transfer ice blocks from a low point to a high point in a limited space by using the ice block conveying device, so that ice making cells in the ice maker are not required to be arranged above the ice storage box 1, namely, the relative positions of the ice making cells and the ice storage box 1 in the ice maker are not limited, and the ice blocks falling down from the ice making cells can fall onto the ice sliding unit 6, so that the arrangement positions of the ice making cells in the ice maker are more flexible. In addition, because the ice cube tray in the ice maker is not required to be arranged above the ice storage box 1, the height of the ice maker comprising the ice cube tray and the ice storage box 1 in the vertical direction is greatly reduced, and the installation of the whole ice maker in refrigeration equipment such as a refrigerator is more flexible.
Further, in order to ensure that the skating unit 6 is always kept balanced and prevented from shaking during the up-and-down movement process, a sliding rail extending along the height direction of the ice storage box 1 is arranged on the outer wall of the ice storage box 1, one end of the skating unit 6 is connected with the lifting driving unit, and a sliding block in sliding fit with the sliding rail is arranged at the other end of the skating unit 6.
In one embodiment, as shown in fig. 5, the skating unit 6 includes an ice-skating panel 6-1, left and right side panels 6-3, the ice-skating panel 6-1 being extended to the ice bank 1 to be inclined downward from one end thereof away from the ice bank 1; the left side plate and the right side plate 6-3 are respectively arranged at two sides of the ice skating plate 6-1. Further, in order to improve the bearing capacity of the ice skating board 6-1, the ice skating unit 6 further comprises a front side board 6-2, wherein the top end of the front side board 6-2 is connected with one end of the ice skating board 6-1 far away from the ice storage box 1, and the bottom end of the front side board extends downwards. More preferably, a plurality of protrusions 6-1-1 are provided on the surface of the ice sheet 6-1 to reduce the contact area of ice cubes with the ice sheet 6-1 and prevent the ice cubes from being adhered to the ice sheet 6-1. Wherein, the shape of the bulge 6-1-1 can be but not limited to a burr shape, a long strip shape or a semispherical shape. When the bulges 6-1-1 are in the shapes of burs or hemispheres, all the bulges 6-1-1 are uniformly distributed on the surface of the skating board 6-1; when the protrusions 6-1-1 are in a strip shape, all the protrusions 6-1-1 are sequentially arranged along the length direction of the skating board 6-1.
In one embodiment, the ice bank 1 includes: the U-shaped groove 1-1 is used for storing ice blocks, and an ice feeding port is formed in the side wall of the U-shaped groove 1-1; and the guide plate 1-2 extends downwards from the lower end of the ice feeding port, and the top surface of the ice sliding unit 6 and the guide plate 1-2 jointly define a bearing space of ice blocks. Therefore, when the lifting driving unit drives the movable shaft seat 5 to move up and down, the ice skating unit 6 can move close to the guide plate 1-2. When the ice skating unit 6 moves to the top end of the guide plate 1-2, the ice feeding port is just opened, and ice cubes carried on the ice skating unit 6 can slide into the U-shaped groove 1-1 through the ice feeding port by means of self gravity.
In one embodiment, the side of the guide plate 1-2 facing the skating unit 6 is provided with ribs 1-3. Due to the existence of the ribs 1-3, in the process that the ice-skating unit 6 moves upwards along the guide plate 1-2 in a clinging mode, ice blocks carried on the ice-skating unit 6 are extruded by the ribs 1-3 when passing through the ribs 1-3, and adjacent ice blocks move relatively, so that the ice blocks are prevented from being bonded together in the conveying process. Furthermore, the number of the convex edges 1-3 is multiple, and the convex edges 1-3 are sequentially arranged along the height direction of the guide plate 1-2. In addition, in order to extend the contact time of the ribs 1-3 with the ice cubes, the ribs 1-3 are preferably arranged to be inclined downward.
In one embodiment, a reset member is provided on the rotating shaft of the turnover door 2, and the reset member is used for providing a driving force for driving the turnover door 2 to close the ice conveying port. Wherein, the piece that resets includes torsion spring 7, and torsion spring 7 cover is established on the axis of rotation of upset door 2. The advantage of this is that the torsion spring 7 is continuously tightened as the turnover door 2 is gradually opened during the upward movement of the moving shaft seat 5 driven by the lifting drive unit. Therefore, when the lifting driving unit drives the moving shaft seat 5 to move downwards, the turnover door 2 can rapidly close the ice conveying opening under the dual driving of the restoring force of the torsion spring 7 and the driving rod 3. In one embodiment, as shown in fig. 6, the movable shaft seat 5 includes a vertical plate 5-1, horizontal plates 5-2 extending outward are disposed on both left and right sides of the vertical plate 5-1, the two horizontal plates 5-2 are respectively connected with the skating unit 6 and the lifting driving unit, and the top surface of the vertical plate 5-1 is an inclined surface from top to bottom. Further, the top surface of the vertical plate 5-1 is inclined downwards to avoid the influence on the sliding of ice blocks when the turnover plate is opened.
In one embodiment, the bottom end of the driving rod 3 is attached to the top surface of the moving shaft seat 5, that is, the side of the bottom end of the driving rod 3 facing the moving shaft seat 5 is an inclined plane, and the inclined angle of the inclined plane is the same as the inclined angle of the top surface of the moving shaft seat 5. Further, the side wall of the bottom end of the driving rod 3 protrudes outward to increase the contact area of the driving rod 3 and the movable shaft seat 5.
In one embodiment, the lifting driving unit comprises a screw 4-2, a motor support 4-3 and a driving motor 4-1 arranged on the top of the motor support 4-3; the movable shaft seat 5 is provided with a threaded hole 5-2-1, the top end of the screw rod 4-2 is connected with the driving motor 4-1, and the bottom end of the screw rod is in threaded fit with the threaded hole 5-2-1.
Therefore, after the driving motor 4-1 is started, the screw 4-2 can rotate continuously under the driving of the driving motor 4-1, and then the movable shaft seat 5 can be driven to move along the axial direction of the screw 4-2. Specifically, the method comprises the following steps: when the screw rod 4-2 rotates forward, the movable shaft seat 5 screwed at the bottom of the screw rod 4-2 moves upwards along the axial direction of the screw rod 4-2. When the screw 4-2 is reversely rotated, the movable shaft seat 5 screwed on the top of the screw 4-2 is moved downward along the axial direction of the screw 4-2.
In one embodiment, the lifting drive unit comprises a cylinder arranged above the mobile shaft seat, and a piston rod of the cylinder is connected with the mobile shaft seat 5. After the cylinder is started, when the piston of the cylinder reciprocates along the cylinder, the movable shaft seat 5 can move up and down together under the driving of the piston rod of the cylinder.
Example 2
Referring to fig. 7 to 10, the structure and principle of the ice conveying device in this embodiment are the same as those in embodiment 1, and the description of this embodiment is omitted.
The difference is that, considering that all ice cubes on the ice making cells 8 may not fall off together at the same time in the ice shedding process, that is, after most of the ice cubes on the ice making cells 8 slide on the top surface of the ice skating unit 6, in the process that the lifting driving unit drives the ice skating unit 6 to transport the ice cubes upwards, the remaining ice cubes on the ice making cells 8 may slowly slide out of the ice shedding port 8-1 of the ice making cells 8, so that, in order to avoid that the ice units 6 transport the ice to the ice storage box 1, the ice cube transporting device in this embodiment further includes:
the ice cube tray 8 is arranged at one end of the ice sliding unit 6 far away from the ice storage box 1;
the ice blocking plate 9 is used for opening and closing the ice removing opening 8-1 of the ice making grid 8, and the ice blocking plate 9 is rotationally connected to the ice making grid 8 through a rotating shaft; the ice shutter 9 is configured to: under the condition that the skating unit 6 is positioned at the ice-shedding port 8-1, the ice baffle 9 opens the ice-shedding port 8-1 under the interference of the skating unit 6;
and the driving piece is connected with the ice blocking plate 9 and is used for providing a driving force for closing the ice shedding opening 8-1 of the ice making grid 8 by the ice blocking plate 9.
Therefore, in the process that the lifting driving unit drives the ice sliding unit 6 to move downwards, after the bottom surface of the ice sliding unit 6 is contacted with the ice blocking plate 9, the ice blocking plate 9 rotates downwards under the pressing action of the ice sliding unit 6 along with the continuous downward movement of the ice sliding unit 6 until the ice blocking plate 9 opens the ice shedding port 8-1 of the ice making grid 8. At this time, the top surface of the ice-skating unit 6 is just aligned with the ice-release opening 8-1 of the ice-making housing 8, so that the ice cubes slid out from the ice-release opening 8-1 can be slid to the top surface of the ice-skating unit 6 by inertia.
In the process that the lifting drive unit drives the skating unit 6 to move upwards, when the skating unit 6 is separated from the ice blocking plate 9, the downward pressure is not applied to the ice blocking plate 9 by the skating unit 6, at the moment, the ice blocking plate 9 is only driven by the driving element to rotate upwards by the driving element, and the ice blocking plate 9 is driven by the driving element to rotate upwards until the ice shedding port 8-1 of the ice making grid 8 is closed. Therefore, during the process of conveying the ice blocks to the ice storage box 1 by the ice skating unit 6, the ice blocks remaining in the ice making cells 8 cannot slip out of the ice release openings 8-1 of the ice making cells 8.
Therefore, when the lifting driving unit drives the ice sliding unit 6 to move up and down, the ice blocking plate 9 can be indirectly controlled to open or close the ice shedding port 8-1 of the ice making grid 8, so that the phenomenon that residual ice in the ice making grid 8 falls off in the process of conveying ice blocks to the ice storage box 1 by the ice sliding unit 6 is avoided.
In one embodiment, in order to increase the contact area with the ice shutter 9 during the downward movement of the skating unit 6, the bottom surface of the ice shutter 9 has a plurality of ribs 9-1 extending downward, and the plurality of ribs 9-1 are sequentially arranged along the length direction of the ice shutter 9. Therefore, when the ice blocking plate 9 is in a closed state, namely the top surface of the ice blocking plate 9 is covered on the ice shedding port 8-1 of the ice making grid 8, the raised strips 9-1 arranged on the bottom surface of the ice blocking plate 9 just turn over to the position right below the ice skating unit 6 along with the ice blocking plate 9. Therefore, when the skating unit 6 moves downward by a set distance, the skating unit 6 presses the protrusion strips 9-1, and the ice blocking plate 9 is driven to rotate downward.
In one embodiment, the driving member is a tension spring 10, and one end of the tension spring 10 is connected to the ice cube tray 8 and the other end thereof is connected to the rotation shaft. The two sides of the ice baffle 9 are both provided with tension springs 10, and the ice baffle 9 is provided with a convex column 9-2 for hanging the tension springs 10. Therefore, when the ice skating unit 6 presses the ice blocking plate 9 to rotate downwards, the tension spring 10 is continuously stretched along with the gradual opening of the ice removing opening 8-1 of the ice making grid 8. Thus, when the skating unit 6 moves upward and is separated from the ice blocking plate 9, the ice blocking plate 9 rapidly closes the ice-releasing port 8-1 by being driven by the restoring force of the tension spring 10.
It should be noted that the driving member may be a pair of magnets or a torsion spring sleeved on the rotating shaft, besides the tension spring 10. When the driving element is a pair of magnets, one of the magnets is arranged on the bottom surface of the ice baffle plate 9, the other magnet is attached to the ice making grid 8 and positioned below the ice baffle plate 9, and the two magnets have the same polarity. Therefore, when the ice skating unit 6 presses the ice blocking plate 9 to rotate downwards, the magnets on the ice blocking plate 9 gradually approach the magnets on the ice making grid 8 along with the gradual opening of the ice shedding port 8-1 of the ice making grid 8, and the repulsive force between the two magnets gradually increases. Thus, when the skating unit 6 moves upward and is separated from the ice blocking plate 9, the ice blocking plate 9 rapidly closes the ice discharge opening 8-1 by the repulsive force and the inertia.
Example 3
The invention also provides an ice maker, which comprises the ice conveying device. The structure and principle of the ice conveying device in this embodiment are the same as those in embodiment 1, and the description of this embodiment is omitted. By arranging the ice conveying device in the ice maker, ice can be transferred from a low point to a high point in a limited space, and the ice output at a single time is large in quantity, low in noise, high in transportation efficiency and high in reliability.
