Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment, and more particularly to an ice-making device with an ice-stirring function and a refrigerator having the same. Background Technology

[0002] With the continuous development of society and the improvement of people's living standards, people's needs for refrigerators are no longer limited to refrigerating or freezing food; they also have higher requirements for the user experience.

[0003] Most refrigerators on the market now have an ice storage box inside the door for ice dispensing. When a user needs to dispense ice, they press the ice dispensing button, and the ice-crushing motor drives the ice blades in the ice storage box to rotate, thus delivering whole or crushed ice to the dispenser as needed. Most ice storage boxes also have an ice-stirring mechanism, which agitates the ice cubes while the ice blades are rotating, reducing the stickiness of the ice.

[0004] Temperature fluctuations in the ice-making room, activation of the defrosting heating wire, or the user opening the door can cause the ice in the ice storage box to melt, resulting in the ice sticking together. If the user does not use the ice dispensing function for a long time, the ice stirring mechanism cannot be triggered, thus the problem of ice sticking together in the ice storage box cannot be avoided.

[0005] In view of this, there is an urgent need for a new type of refrigerator to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an ice-making device and a refrigerator having the same, for solving the problem of ice blocks sticking together in the ice storage box.

[0007] To achieve the above-mentioned objective, the present invention provides an ice-making device, including a housing, an ice maker disposed within the housing, and an ice storage box for storing ice blocks. The ice-making device further includes an ice-stirring rod disposed in the ice storage box and a drive assembly for driving the ice-stirring rod to rotate. The drive assembly is configured to drive the ice-stirring rod to rotate when no ice is taken for a preset time.

[0008] As a further improvement of the present invention, if ice is not removed within a preset time, the driving component drives the ice-stirring rod to rotate back and forth between a first preset position and a second preset position.

[0009] As a further improvement of the present invention, the driving assembly includes a power element, a transmission wheel driven by the power element, and a transmission component meshing with the transmission wheel. The ice-stirring rod is fixed on the transmission component. A magnet is fixed on the transmission wheel. A first Hall switch and a second Hall switch are spaced apart on the side wall of the housing corresponding to the transmission wheel. The driving assembly drives the transmission wheel to rotate, causing the magnet to move between the first Hall switch and the second Hall switch. When the transmission wheel rotates to the point where the first Hall switch is turned on, the ice-stirring rod is located at a first preset position. When the transmission wheel rotates to the point where the second Hall switch is turned on, the ice-stirring rod is located at a second preset position.

[0010] As a further improvement of the present invention, the first Hall switch and the second Hall switch are located on the same circumference, and the center of the circumference is located on the shaft of the transmission wheel.

[0011] As a further improvement of the present invention, the distances from the first Hall switch and the second Hall switch to the center of the circumference are the same as the distance from the magnet to the shaft of the transmission wheel.

[0012] As a further improvement of the present invention, the bottom of the ice storage box is provided with an opening and a baffle plate for partially covering the opening. The baffle plate and the bottom of the ice storage box form an opening for ice blocks to fall into the ice storage box. The ice making device also includes an ice crushing assembly fixed to the lower side of the ice storage box. The ice crushing assembly includes an ice bucket communicating with the opening and a moving ice blade located inside the ice bucket and rotating synchronously with the ice stirring rod. When the ice stirring rod is in a first preset position, the angle between the moving ice blade and the edge of the baffle plate is a first preset maximum angle.

[0013] As a further improvement of the present invention, the ice crushing assembly further includes a shell fixed to the bottom of the ice storage box, the ice bucket being movably connected to the shell, and the bottom of the shell having an ice discharge port communicating with the ice bucket;

[0014] The moving ice blades are two sets of moving ice blades arranged vertically inside the ice bucket. When the ice stirring rod is in the second preset position, the angle between the moving ice blade near the ice discharge port and the edge of the ice discharge port is the second preset maximum angle.

[0015] As a further improvement of the present invention, the driving assembly includes a power element and a transmission wheel driven by the power element; the periphery of the ice bucket is evenly distributed with transmission teeth that mesh with the transmission wheel, and the ice churning rod and the moving ice blade are both fixed on the ice bucket.

[0016] As a further improvement of the present invention, when the angle between the moving blade and the edge of the baffle is a first preset maximum angle, the moving blade is located at the first blade position; when the angle between the moving blade near the ice discharge port and the edge of the ice discharge port is a second preset maximum angle, the moving blade is located at the second blade position; the angle between the first blade position and the second blade position is 50°.

[0017] To achieve the above-mentioned objectives, the present invention also provides a refrigerator, including a cabinet and a door, wherein an ice-making chamber is provided on the door, and an ice-making device as described in any of the above technical solutions is provided in the ice-making chamber.

[0018] The ice-making device of the present invention is equipped with an ice-stirring rod in the ice storage box. When no ice is taken out for a preset time, the driving component drives the ice-stirring rod to rotate, thereby stirring the ice blocks in the ice storage box and solving the problem of ice blocks sticking together in the ice storage box due to the user not taking out ice for a long time.

[0026] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0027] It should be understood that terms such as "upper," "lower," "outer," and "inner," used herein to indicate spatial relative position, are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms "spatial relative position" may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0028] The present invention provides an ice-making device and a refrigerator having the same. The refrigerator includes a cabinet and a door. An ice-making compartment is provided on the door. An ice-making device 100 is provided in the ice-making compartment. The ice-making device 100 is placed on the door, which makes it convenient for users to take out ice and does not occupy the storage space inside the refrigerator cabinet.

[0029] Further, please refer to Figures 1 to 6 As shown, the ice-making device 100 includes a housing 10, an ice maker disposed within the housing 10, and an ice storage box 20 for storing ice cubes. The ice-making device 100 also includes an ice-stirring rod 30 disposed in the ice storage box 20, and a drive assembly for driving the ice-stirring rod 30 to rotate. The drive assembly is configured to drive the ice-stirring rod 30 to rotate when no ice is taken out for a preset time. The rotation of the ice-stirring rod 30 causes the ice cubes in the ice storage box 20 to rotate as well, thereby solving the problem of ice cubes sticking together in the ice storage box 20 due to the user not taking out ice for a long time.

[0030] In one specific embodiment, the ice storage box 20 is located directly below the ice maker. After the ice maker finishes making ice, the ice cubes fall into the ice storage box 20 by flipping the ice tray. Specifically, the shape and size of the ice storage box 20 match the ice maker. The ice stirring rod 30 inside the ice storage box 20 is positioned near the bottom of the ice storage box 20, so that when the ice stirring rod 30 rotates, it drives the ice cubes at the bottom of the ice storage box 20 to stir. The rotation of the ice cubes at the bottom of the ice storage box 20 also drives the ice cubes at the top to stir, thereby improving the ice stirring efficiency of the ice stirring rod 30.

[0031] In this invention, the preset time can be selected according to the actual situation of the ice-making device 100. When the preset time is exceeded, the ice in the ice storage box 20 will melt and stick together. For example, the preset time can be set to 24 hours. Of course, the selection of the preset time is not limited to this.

[0032] Furthermore, if ice is not removed within a preset time, the driving component drives the ice stirring rod 30 to reciprocate between a first preset position and a second preset position. The ice stirring rod 30 reciprocates within the ice storage box 20, making the ice blocks in the ice storage box 20 more thoroughly stirred, further preventing the ice in the ice storage box 20 from sticking together.

[0033] Furthermore, the drive assembly includes a power element, a transmission wheel 40 driven by the power element, and a transmission component meshing with the transmission wheel 40. The ice-stirring rod 30 is fixed to the transmission component. By utilizing the meshing of the transmission wheel 40 and the transmission component, the rotation of the power element is ultimately converted into the rotation of the ice-stirring rod 30. The power element can be selected as a motor or an electric motor, but is not limited to these.

[0034] Furthermore, a magnet 50 is fixed on the transmission wheel 40. A first Hall switch 60 and a second Hall switch 70 are spaced apart on the sidewall of the housing 10 corresponding to the transmission wheel 40. The drive assembly drives the transmission wheel 40 to rotate, causing the magnet 50 to move between the first Hall switch 60 and the second Hall switch 70. Specifically, when the transmission wheel 40 rotates to the point where the magnet 50 activates the first Hall switch 60, the ice-stirring rod 30 is located at a first preset position; when the transmission wheel 40 rotates to the point where the magnet 50 activates the second Hall switch 70, the ice-stirring rod 30 is located at a second preset position. By using the magnet 50 to activate either the first Hall switch 60 or the second Hall switch 70, the position of the ice-stirring rod 30 is determined, thereby achieving precise control of the rotational position of the ice-stirring rod 30. Simultaneously, the sensing method of the Hall switches and the magnet 50 does not require winding within the ice-making device 100, thus not occupying space within the ice-making device 100.

[0035] Specifically, the first Hall switch 60 and the second Hall switch 70 are located on the same circumference, and the center of the circumference is located on the shaft of the transmission wheel 40. Preferably, the distance from the first Hall switch 60 and the second Hall switch 70 to the center of the circumference is the same as the distance from the magnet 50 to the shaft of the transmission wheel 40, so that during one rotation of the transmission wheel 40, the magnet 50 on the transmission wheel 40 sequentially turns on the first Hall switch 60 and the second Hall switch 70, thereby determining whether the ice-stirring rod 30 is located at the first preset position or the second preset position.

[0036] In a specific embodiment of the present invention, please refer to Figure 4 , Figure 6 As shown, the bottom of the ice storage box 20 is provided with an opening 90, which is used to cover part of the baffle 805 of the opening 90. The baffle 805 and the bottom of the ice storage box form an opening 8051 for ice blocks inside the ice storage box to fall into.

[0037] The ice-making device 100 further includes an ice-crushing assembly 80 fixed to the lower side of the ice storage box 20. The ice-crushing assembly 80 includes an ice bucket 801 communicating with the opening 8051 and a moving ice blade 804 located inside the ice bucket 801 and rotating synchronously with the ice-stirring rod 30. When the ice-stirring rod 30 is in a first preset position, the angle between the moving ice blade 804 and the edge of the baffle 805 is a first preset maximum angle. It can be understood that the edge of the baffle 805 refers to the edge of the baffle 805 that intersects with the rotation trajectory of the moving ice blade 804, and the first preset maximum angle refers to the maximum angle at which the ice cubes in the ice storage box 20 cannot fall out during the ice-stirring process.

[0038] Furthermore, the ice crushing assembly 80 also includes a housing 806 fixed to the bottom of the ice storage box 20, and the ice bucket 801 is movably connected to the housing 806. The bottom of the housing 806 is provided with an ice discharge port 807 communicating with the ice bucket 801. Specifically, the ice making device 100 also has a through-hole corresponding to the position of the ice discharge port 807. When the ice making device 100 needs to discharge ice, the ice blocks are discharged to the ice dispensing area of ​​the refrigerator through the through-hole.

[0039] Furthermore, the moving ice blades 804 are two sets of moving ice blades 804 arranged vertically inside the ice bucket 801. When the ice stirring rod 30 is in the second preset position, the angle between the moving ice blade 804 near the ice discharge port 807 and the edge of the ice discharge port 807 is the second preset maximum angle. It can be understood that the two sets of moving ice blades 804 include an upper moving ice blade near the baffle plate 805 and a lower moving ice blade near the ice discharge port 807. The projections of the upper and lower moving ice blades in the vertical direction coincide. The edge of the ice discharge port 807 refers to the edge of the ice discharge port 807 that intersects with the rotation trajectory of the lower moving ice blade. Moreover, the second preset maximum angle refers to the maximum angle at which the ice block in the ice storage box 20 cannot fall out during the ice stirring process, thereby preventing the ice block in the ice bucket 801 from falling out of the ice making device 100 through the ice discharge port 807.

[0040] In this embodiment, when the angle between the moving ice blade 804 and the edge of the baffle 805 is a first preset maximum angle, the moving ice blade 804 is located at the first ice blade position; when the angle between the moving ice blade 804 near the ice discharge port 807 and the edge of the ice discharge port 807 is a second preset maximum angle, the moving ice blade is located at the second ice blade position. The angle between the first ice blade position and the second ice blade position is 50°, which ensures that the ice blocks in the ice making device 100 will not fall from the ice discharge port 807, and also allows the ice stirring rod 30 to rotate to the maximum angle, improving the effect of preventing ice blocks from sticking together.

[0041] Furthermore, the transmission component is an ice bucket 801, and transmission teeth 802 that mesh with the transmission wheel 40 are evenly distributed on the periphery of the ice bucket 801. The ice stirring rod 30 and the moving ice blade 804 are both fixed on the ice bucket 801. When the power element drives the transmission wheel 40 to rotate, the transmission wheel 40 drives the ice bucket 801 to rotate through the transmission teeth 802 that mesh with it, thereby driving the ice stirring rod 30 and the moving ice blade 804 to rotate synchronously.

[0042] Furthermore, the ice-crushing assembly 80 is fitted to the bottom surface of the ice storage box 20, making the overall structure of the ice-making device 100 more compact. The ice-crushing assembly 80 also includes a fixed ice blade 808 and a fixed shaft 803 passing through the ice bucket 801. The bottom of the fixed shaft 803 is connected to the outer shell 806 in the ice-crushing assembly 80, and the top of the fixed shaft 803 extends into the ice storage box 20 through the opening 90. The ice-stirring rod 30 and the moving ice blade 804 are movably connected to the fixed shaft 803, and the fixed ice blade is fixedly connected to the fixed shaft 803, making the ice-making device 100 compact in structure, and the ice-making device 100 can stir ice while crushing it.

[0043] The present invention also provides a method for stirring ice based on the ice-making device described above, the structure of which is as described above and will not be repeated here.

[0044] Please see Figure 7 The diagram shows a flowchart of an ice-stirring method according to a specific embodiment of the present invention. The ice-stirring method specifically includes the following steps:

[0045] S100: Determine whether the ice storage box has not been used for ice removal for more than a first preset time. If so, start the drive component to drive the ice churning rod located in the ice storage box to rotate.

[0046] In this invention, the preset time can be selected according to the actual situation of the ice-making device. For example, in this embodiment, the preset time can be set to 24 hours. When the preset time is exceeded, the ice in the ice storage box will melt and stick together. Therefore, by activating the drive component to drive the ice stirring rod to rotate, the ice in the ice storage box will also rotate, thereby solving the problem of ice sticking together in the ice storage box due to the user not removing ice for a long time.

[0047] In this embodiment, step S100 specifically involves driving the ice-stirring rod to reciprocate between a first preset position and a second preset position. The reciprocating rotation of the ice-stirring rod within the ice storage box ensures that the ice blocks are more thoroughly agitated, further preventing the ice from sticking together.

[0048] Specifically, the angle between the first preset position and the second preset position is 50°, which ensures that the ice in the ice-making device will not fall from the ice discharge port, and also allows the ice stirring rod to rotate to the maximum angle, thus improving the effect of preventing ice from sticking together.

[0049] Furthermore, prior to step S100, the ice-stirring method further includes the following steps:

[0050] S200, acquire the ice removal completion signal;

[0051] S300, start the drive assembly, drive the ice churning rod located in the ice storage box to rotate to the first preset position.

[0052] Each time a user finishes taking ice, the ice-stirring rod rotates to the first preset position. This allows the ice-stirring rod to controllably rotate back and forth between the first and second preset positions when ice needs to be stirred, making the ice cubes in the ice storage box more thoroughly stirred and preventing the ice cubes in the ice storage box from sticking together.

[0053] In this embodiment, "driving the ice stirring rod to reciprocate between the first preset position and the second preset position" specifically means: driving the ice stirring rod located in the ice storage box to rotate from the first preset position to the second preset position in a first set direction and staying at the second preset position for a second preset time;

[0054] The drive assembly is activated to drive the ice-stirring rod to rotate in the opposite direction from the second preset position to the first preset position, and then stop at the first preset position for a second preset time.

[0055] In this invention, the ice-stirring rod is rotated in a predetermined direction by changing the direction of the power component. Specifically, the first predetermined direction can be set to forward rotation, that is, the ice-stirring rod rotates forward from a first preset position to a second preset position, stays at the second preset position for a second preset time, then rotates in the opposite direction from the second preset position to the first preset position, and then stays at the first position for a preset time. By controlling the direction of the ice-stirring rod, the range of motion of the ice-stirring rod is controlled.

[0056] Furthermore, in this embodiment, by setting a second preset time, the power component returns to a stable state after the ice-stirring rod reaches the preset position before driving the ice-stirring rod to rotate, thus ensuring the accuracy of the ice-stirring rod's rotation position. Optionally, the second preset time is set to 5 seconds, but it is not limited to this.

[0057] Furthermore, during the process of "driving the ice-stirring rod to reciprocate between the first preset position and the second preset position", the ice-stirring method also includes the following steps:

[0058] S400: Count the number of times the ice throttle rotates and determine whether the number of rotations exceeds a preset number. If yes, turn off the drive component; otherwise, drive the ice throttle to continue rotating until the preset number of rotations is reached.

[0059] The ice stirring rod is counted as one rotation when it rotates from the first preset position to the second preset position and then returns to the first preset position. Preferably, "counting the number of rotations of the ice stirring rod" specifically means counting the number of times the ice stirring rod rotates to the second preset position.

[0060] In this invention, by setting a preset number of reciprocating movements between a first preset position and a second preset position, the problem of ice sticking together in the ice storage box due to prolonged periods without ice removal is solved. The preset number of reciprocating movements can be selected according to actual needs; for example, 5 reciprocating movements can be used, but this is not a limitation.

[0061] In this invention, a first Hall switch is provided in the rotation direction of the drive component. When the drive component rotates, thereby causing the magnet on the drive component to activate the first Hall switch, the ice-stirring rod is located at a first preset position. A second Hall switch is provided in the rotation direction of the drive component, spaced apart from the first Hall switch. When the drive component rotates, thereby causing the magnet on the drive component to activate the second Hall switch, the ice-stirring rod is located at a second preset position. By using the magnet to activate either the first or second Hall switch, the position of the ice-stirring rod is determined, thereby achieving precise control of the rotation position of the ice-stirring rod. Furthermore, the sensing method of the Hall switches and magnets does not require wiring within the ice-making device, thus not occupying space within the ice-making device.

[0062] Furthermore, after the step of "determining whether the ice storage box has not been removed for a longer period than a first preset time" and before the step of "starting the drive component", the ice-stirring method further includes:

[0063] S500 determines whether the ice-making chamber has entered defrosting mode. If so, the drive component is started after defrosting is completed and after a third preset time delay.

[0064] When the ice-making compartment enters defrosting mode, the temperature inside the ice storage box rises. Since the ice in the ice storage box is wet, a third preset time is allowed to refreeze the ice into dry ice before the drive assembly is activated to rotate the ice churning rod, thus saving energy for the refrigerator. Preferably, the third preset time is 20 minutes, but it is not limited to this.

[0065] Furthermore, after the step of "determining whether the ice storage box has not been removed for a longer period than a first preset time" and before the step of "starting the drive component", the ice-stirring method further includes:

[0066] S600, determine whether the door of the ice-making room is open. If so, start the drive component after the door is closed and a fourth preset time is delayed.

[0067] When the door is opened, the temperature inside the ice storage box rises. Since the ice inside is wet, a fourth preset time is allowed to refreeze the ice into dry ice before the drive assembly is activated to rotate the ice churning rod, thus saving energy for the refrigerator. Preferably, the fourth preset time is 40 minutes, but it is not limited to this.

[0068] The ice-making device of the present invention is equipped with an ice-stirring rod in the ice storage box. When no ice is taken out for a preset time, the driving component drives the ice-stirring rod to rotate, thereby stirring the ice blocks in the ice storage box and solving the problem of ice blocks sticking together in the ice storage box due to the user not taking out ice for a long time.

[0069] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0070] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
