[0049] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0050] With the diversification of life needs, small, multifunctional drinking water products are becoming more popular. They are small in size, take up less space, and are equipped with more functions to meet the beverage mixing needs of different people. In related technologies, some products with ice-making functions can store ice cubes in ice storage bins after they are produced. However, existing ice storage bins are mostly rectangular, which makes it difficult to remove ice cubes, leaving room for improvement. In addition, ice cubes are prone to accumulation, affecting ice production efficiency.

[0051] The ice discharging mechanism 1 according to an embodiment of the present invention will be described below with reference to FIG. 1 to FIG. 8 .

[0052] According to the present invention, the ice-discharging mechanism 1 includes a shell 11, an ice-discharging shell 12, an ice-discharging screw 13 and a driving member 14. The shell 11 is formed with a receiving cavity and an ice-discharging port 1291 connected to the receiving cavity; the ice-discharging shell 12 is accommodated in the receiving cavity and an inclined ice-discharging ramp is formed on the ice-discharging shell 12; one end of the ice-discharging screw 13 is arranged at one end of the ice-discharging shell 12, and the other end of the ice-discharging screw 13 spirally extends to the ice-discharging port 1291, and the ice-discharging screw 13 extends obliquely relative to the ice-discharging port 1291 and has the same inclination direction as the ice-discharging ramp; the driving member 14 is suitable for driving the ice-discharging screw 13 to rotate.

[0053] Specifically, the structure of the ice-discharging mechanism 1 is shown in Figures 1 and 4. A receiving cavity is formed in the shell 11. The ice-discharging shell 12 and the ice-discharging screw 13 are both accommodated in the receiving cavity of the shell 11. An inclined ice-discharging ramp is formed on the ice-discharging shell 12. The ice-discharging screw 13 is arranged on the ice-discharging ramp. One end of the ice-discharging screw 13 is arranged at one end of the ice-discharging shell 12, and the other end of the ice-discharging screw 13 spirally extends to the ice-discharging port 1291. The inclination direction of the ice-discharging screw 13 is consistent with the inclination of the ice-discharging ramp. In the same direction, the ice-discharging screw 13 can rotate under the drive of the driving member 14, thereby driving the ice cubes to move along the ice-discharging ramp to the ice-discharging port 1291; wherein, the driving member 14 can be constructed as a driving motor, and the driving motor can drive the ice-discharging screw 13 to rotate forward and reverse. When the ice cubes enter the accommodating chamber and fall into the ice-discharging shell 12, the rotation of the ice-discharging screw 13 can drive the ice cubes to move to the ice-discharging port 1291 and be discharged from the ice-discharging port 1291, thereby meeting the user's ice demand.

[0054] The ice discharging ramp is inclined from bottom to top and the ice discharging port 1291 is located at the top of the ice discharging ramp, which improves the position of the ice discharging port 1291 and makes the cross-sectional area between the upper surface of the ice discharging shell 12 and the accommodating chamber gradually increase from bottom to top, thereby increasing the volume of ice stored in the shell 11, providing users with a large amount of ice and convenient use.

[0055] According to the ice discharging mechanism 1 of the present invention, an ice discharging shell 12 is provided in the shell 11, and an ice discharging ramp extending obliquely from bottom to top is formed on the ice discharging shell 12. The ice discharging screw 13 is obliquely arranged and has the same inclination direction as the ice discharging ramp to drive the ice cubes to move along the ice discharging ramp to the ice discharging port 1291. The ice discharging port 1291 is arranged at the top of the ice discharging ramp to raise the position of the ice discharging port 1291 to prevent ice cubes from accidentally falling and facilitate users to take ice from the outside of the shell 11. At the same time, the cross-sectional area between the upper surface of the ice discharging shell 12 and the accommodating cavity gradually increases from bottom to top, thereby increasing the volume for storing ice cubes in the shell 11, providing users with a large amount of ice cubes for convenience.

[0056] According to one embodiment of the present invention, the ice discharge shell 12 includes a first mounting plate 121, a base plate 122 and a ramp plate 123. The first mounting plate 121 is suitable for being fixed to one end of the ice discharge screw 13; one end of the base plate 122 is connected to the first mounting plate 121 and is located at the bottom of the first mounting plate 121; the ramp plate 123 is arranged at the other end of the base plate 122, and an ice discharge ramp is formed on the ramp plate 123 and is inclined relative to the base plate 122 to extend to the ice discharge port 1291.

[0057] The ice discharging shell 12 is provided with a first mounting plate 121, a bottom plate 122 and a ramp plate 123. The first mounting plate 121 is provided at one end of the bottom of the ice discharging shell 12, and one end of the ice discharging screw 13 is fixedly mounted on the first mounting plate 121. A mounting inclined surface is formed on the first mounting plate 121, and the mounting inclined surface and the ice discharging ramp are arranged at an angle. One end of the ice discharging screw 13 is fixedly mounted on the first mounting plate 121, and the other end of the ice discharging screw 13 spirally extends to the ice discharging port 1291, so that the ice discharging screw 13 can drive the ice cubes to move along the ice discharging ramp to the ice discharging port 1291. The first mounting plate 121 is connected to one end of the bottom plate 122, and the bottom plate 122 is provided at the bottom of the first mounting plate 121. The ramp plate 123 is provided at the other end of the bottom plate 122, and an ice discharging ramp is formed on the ramp plate 123, and the ramp plate 123 is inclined relative to the bottom plate 122. The ice outlet 1291 is located at a higher position, so that ice cubes in the storage chamber are prevented from accidentally falling due to the low position of the ice outlet 1291, which affects the user's experience. In addition, since the ice outlet 1291 is at a higher position, when the user takes ice cubes from the ice outlet 1291, it is more convenient to place the container containing ice cubes under the ice outlet 1291, which is convenient for the user to take ice cubes. In addition, the cross-sectional area of ​​the space defined by the side surface of the bottom plate 122 facing the ramp plate 123 and the upper surface of the ramp plate 123 gradually increases from bottom to top, that is, the ice storage space between the bottom plate 122 and the ramp plate 123 gradually increases from bottom to top, so that more ice cubes can be stored in the storage chamber, which is more convenient for the user to use ice cubes.

[0058] According to one embodiment of the present invention, the included angle between the ramp plate 123 and the bottom plate 122 is α1, and satisfies 25°≤α1≤35°.

[0059] Specifically, as shown in Figure 5, the angle between the ramp plate 123 and the bottom plate 122 is α1, and satisfies 25°≤α1≤35°, and the angle between the extension direction of the ramp plate 123 and the plane where the bottom plate 122 is located can be set to 25°, 30°, and 35°, etc. Setting the angle α1 between the plane where the bottom plate 122 is located and the extension direction of the ramp plate 123 to satisfy 25°≤α1≤35° can make the process of ice cubes being output to the ice outlet 1291 along the ramp plate 123 more convenient, avoid the ramp plate 123 from being tilted too much, which causes the ice cubes to easily slide along the ramp plate 123 to the bottom of the ramp plate 123, and also avoid the ice cubes on the ramp plate 123 from accidentally falling due to the ramp plate 123 being tilted too little, affecting the user experience.

[0060] According to one embodiment of the present invention, the rotation axis of the ice-discharging screw 13 is arranged parallel to the ramp plate 123 .

[0061] Specifically, the rotating axis of the ice-discharging screw 13 is arranged parallel to the ramp plate 123. Under the drive of the driving member 14, the ice-discharging screw 13 rotates around the rotating axis. The ice-discharging screw 13 can rotate forward around the rotating axis, and the ice-discharging screw 13 can also rotate reversely around the rotating axis. The rotating axis of the ice-discharging screw 13 is arranged parallel to the ramp plate 123 to ensure that the distance between the ice-discharging screw 13 and the ramp plate 123 remains stable during the rotation of the ice-discharging screw 13. During the rotation of the ice-discharging screw 13, the outer peripheral wall of the ice-discharging screw 13 stops against the ice cubes on the ramp plate 123, so as to drive the ice cubes to rise along the ramp plate 123 and be transmitted to the ice outlet 1291. If there is an angle between the extension direction of the rotating axis of the ice-discharging screw 13 and the ramp plate 123, the ice cubes will fall to the bottom of the ramp plate 123, affecting the ice-discharging efficiency.

[0062] According to one embodiment of the present invention, the minimum distance between the outer periphery of the ice-discharging screw 13 and the ice-discharging ramp is d and satisfies 11 mm ≤ d ≤ 15 mm.

[0063] Specifically, the minimum distance d between the outer peripheral wall of the ice-discharging screw 13 and the ice-discharging ramp satisfies: 11mm≤d≤15mm, that is, the minimum distance d between the outer peripheral wall of the ice-discharging screw 13 and the ice-discharging ramp can be 11mm, 13mm and 15mm, etc., to ensure that the outer periphery of the ice-discharging screw 13 always stops at a position above half of the volume of the ice cube, preventing the ice cube from sliding from between the ice-discharging screw 13 and the ice-discharging ramp to the bottom of the ramp plate 123, affecting the ice-discharging efficiency, and facilitating user use.

[0064] According to one embodiment of the present invention, the angle between the bottom plate 122 and the surface of the first mounting plate 121 facing away from the ice-removing screw 13 is α2 and satisfies 55°≤α2≤65°.

[0065] Specifically, as shown in Figure 5, the angle α2 between the plane where the bottom plate 122 is located and the surface of the first mounting plate 121 facing away from the ice-discharging screw 13 satisfies L: 55°≤α2≤65°, that is, the angle between the surface of the first mounting plate 121 facing away from the ice-discharging screw 13 and the plane where the bottom plate 122 is located can be set to 55°, 60°, and 65°, etc. The ice-discharging screw 13 is arranged perpendicular to the first mounting plate 121, and the angle between the surface of the first mounting plate 121 facing away from the ice-discharging screw 13 and the plane where the bottom plate 122 is located is set to Satisfies: 55°≤α2≤65°, so that the angle between the ice-discharging screw 13 and the plane where the bottom plate 122 is located satisfies greater than or equal to 25° and less than or equal to 35°. At the same time, the angle α1 between the extension direction of the ramp plate 123 and the plane where the bottom plate 122 is located satisfies 25°≤α1≤35°, thereby making the ice-discharging screw 13 parallel to the ice-discharging ramp, preventing ice cubes from sliding to the bottom of the ice-discharging ramp, and increasing the ice output of the ice-discharging screw 13 pushing the ice cubes along the ice-discharging ramp to the ice outlet 1291, without guaranteeing the ice-discharging efficiency, and making it convenient for users to use.

[0066] According to one embodiment of the present invention, the ice outlet shell 12 further includes a first side wall 124 and a second side wall 125. The first side wall 124 and the second side wall 125 are respectively located on both sides of the ramp plate 123 in the width direction, and the distance between the first side wall 124 and the second side wall 125 gradually increases in the direction away from the bottom plate 122.

[0067] Specifically, the ice outlet shell 12 further includes a first side wall 124 and a second side wall 125. As shown in Figures 4 and 5, the first side wall 124 and the second side wall 125 are respectively located on both sides of the width direction of the ramp plate 123. The first side wall 124 and the second side wall 125 are respectively connected to both sides of the width direction of the ramp plate 123. The first side wall 124 and the second side wall 125 can limit the movement space of ice cubes in the width direction of the ramp plate 123, and the distance between the first side wall 124 and the second side wall 125 gradually increases in the direction away from the bottom plate 122, that is, the first side wall 124 and the second side wall 125 are both inclined relative to the ramp plate 123, and ice cubes fall into the first side wall 124 and the second side wall After the side wall 125 is moved, the ice cubes can move along the first side wall 124 and the second side wall 125 to the bottom of the ramp plate 123, avoiding the ice cubes from piling up on the ramp plate 123, thereby affecting the efficiency of the ice-discharging screw 13 in driving the ice cubes to move, making it easier for the ice-discharging screw 13 to drive the ice cubes to move from the bottom of the ramp plate 123 to the ice outlet 1291, thereby improving the ice-discharging efficiency. In addition, the distance between the first side wall 124 and the second side wall 125 gradually increases in the direction away from the bottom plate 122, thereby increasing the space for storing ice cubes between the first side wall 124, the second side wall 125, the bottom plate 122 and the ramp plate 123, thereby increasing the storage space for ice cubes, thereby increasing the ice output of the ice-discharging mechanism 1 and facilitating use by users.

[0068] According to one embodiment of the present invention, the ice shell 12 further includes a third side wall 126, which is arranged on one side of the bottom plate 122 and connected to the first side wall 124. The third side wall 126 is inclined relative to the bottom plate 122 and the distance between the third side wall 126 and the second side wall 125 gradually increases in the direction away from the bottom plate 122.

[0069] Specifically, the ice outlet shell 12 further includes a third side wall 126. As shown in FIG4 , the third side wall 126 is arranged on one side of the bottom plate 122 and is connected to the first side wall 124. The first side wall 124 and the third side wall 126 are arranged on the same side of the bottom plate 122. The first side wall 124 is located near the ice outlet port 1291, and the third side wall 126 is located away from the ice outlet port 1291. The third side wall 126 is inclined relative to the bottom plate 122, and an angle is formed between the first side wall 124 and the third side wall 126. The first side wall 124 and the third side wall 126 define a movement trajectory of ice cubes on one side of the ramp plate 123. After the ice cubes fall into the ice outlet shell 12 , flows along the first side wall 124 and the third side wall 126 to the bottom of the ice discharge shell 12, preventing a large amount of ice cubes from accumulating on the top of the ice discharge shell 12 and blocking the ice cubes from being output to the ice discharge port 1291, thereby ensuring the ice discharge efficiency; the third side wall 126 and the second side wall 125 are respectively located on both sides of the width direction of the bottom plate 122, and the distance between the third side wall 126 and the second side wall 125 gradually increases in the direction away from the bottom plate 122, that is, the cross-sectional area of ​​the space defined by the first side wall 124, the second side wall 125, the bottom plate 122, the ramp plate 123 and the third side wall 126 gradually increases in the direction away from the bottom plate 122, thereby increasing the storage area of ​​the ice cubes.

[0070] According to one embodiment of the present invention, a groove that is recessed toward the bottom is formed on the ramp plate 123 , and an ice-discharging ramp is defined in the groove.

[0071] Specifically, a groove is formed on the ramp plate 123 which is concave toward the bottom, and an ice-discharging ramp is defined in the groove, wherein one end of the ice-discharging screw 13 is connected to the first mounting plate 121 and extends perpendicularly to the first mounting plate 121, and the ice-discharging screw 13 extends along the groove to the ice-discharging port 1291. When ice cubes fall into the ice-discharging shell 12, the ice cubes are guided to the bottom of the ramp plate 123 by the first side wall 124, the second side wall 125 and the third side wall 126 to prevent ice cubes from accumulating on the ramp plate 123. The ice-discharging screw 13 is driven by the driving member 1 4, the ice-discharging screw 13 rotates to drive the ice cubes to move, preventing the ice cubes from accumulating and driving the ice cubes to move along the ice-discharging ramp to the ice-discharging port 1291. A groove concave toward the bottom is formed on the ramp plate 123, so that the distance between the outer periphery of the ice-discharging screw 13 and the groove surface remains stable. In the process of the ice cubes moving along the ice-discharging ramp to the ice-discharging port 1291, the surface of the ice cubes always stops against the groove and the ice-discharging screw 13, which can prevent the ice cubes from sliding, ensure the ice-discharging efficiency of the ice-discharging screw 13, and improve the user experience.

[0072] According to one embodiment of the present invention, a cross section of the groove in the extension direction is configured to be arc-shaped.

[0073] Specifically, the cross-section of the groove in the extension direction is constructed as an arc-shaped surface. During the movement of ice cubes in the groove, the resistance of the ice-discharging ramp to the ice cubes can be reduced, making the movement of the ice cubes smoother. Moreover, since the cross-section of the groove in the extension direction is constructed as an arc-shaped surface, the collision of the ice cubes with the connection between the ice-discharging ramp and the first side wall 124, the second side wall 125 and the third side wall 126 can be avoided, thereby extending the service life of the ice-discharging shell 12. At the same time, the cross-section of the groove is constructed as an arc-shaped surface, which can increase the circulation of ice cubes, improve the ice-discharging efficiency, and provide better user experience.

[0074] According to one embodiment of the present invention, a communication hole 127 penetrating in the thickness direction is formed on the ramp plate 123 , and the communication hole 127 connects the ice discharge ramp with the bottom of the ramp plate 123 .

[0075] Specifically, a connecting hole 127 as shown in Figures 5 and 6 is formed on the ramp plate 123. The connecting hole 127 passes through the ramp plate 123 in the thickness direction, and there are multiple connecting holes 127. The multiple connecting holes 127 are arranged at intervals in the extension direction of the ramp plate 123. The connecting holes 127 connect the ice outlet ramp with the bottom of the ramp plate 123. Since the ice cubes entering the ice outlet shell 12 cannot be discharged at one time, the ice cubes stored in the ice outlet shell 12 will melt. The water formed after the ice cubes melt can flow into the bottom of the ramp plate 123 through the connecting holes 127, thereby slowing down the melting speed of the ice cubes. The water flowing into the bottom of the ramp plate 123 can also be provided to users for use, meeting the user's demand for low-temperature water.

[0076] In some embodiments, a cold water tank 16 is provided at the bottom of the ramp plate 123 , and cold water formed after the ice cubes melt flows into the cold water tank 16 through the connecting hole 127 for storage, which is convenient for users to use.

[0077] According to one embodiment of the present invention, the ice outlet shell 12 further includes an ice guide plate 128, which is respectively connected to the first side wall 124 and the third side wall 126 and is located on the top of the first side wall 124 and the third side wall 126. An ice guide surface is formed on the side of the ice guide plate 128 facing away from the ice outlet ramp.

[0078] Specifically, the ice outlet shell 12 also includes an ice guide plate 128 as shown in Figure 4. The ice guide plate 128 is respectively connected to the first side wall 124 and the third side wall 126 and is located at the top of the first side wall 124 and the third side wall 126. An ice guide surface is formed on the side of the ice guide plate 128 away from the ice outlet ramp. The ice guide surface limits the movement of ice cubes. After passing the ice guide surface, the ice cubes fall into the interior of the ice outlet shell 12 and into the ice outlet ramp. By arranging the ice guide plate 128 on the top of the first side wall 124 and the second side wall 125, the ice cubes can accurately fall into the interior of the ice outlet shell 12 and enter the ice outlet channel, preventing the ice cubes from scattering to other locations and colliding with other parts of the ice outlet mechanism 1, thereby ensuring the safety of the parts of the ice outlet mechanism 1.

[0079] According to one embodiment of the present invention, the ice guide surface is configured as an arc-shaped surface convex toward the ice exit ramp.

[0080] Specifically, the ice guide surface is constructed as an arc-shaped surface protruding toward the ice outlet ramp. After the ice cubes enter the ice guide surface, the collision between the ice cubes and the ice guide surface is reduced, thereby extending the service life of the ice guide plate 128. In addition, the ice guide surface is constructed as an arc-shaped surface protruding toward the ice outlet ramp, so that the capacity of the ice guide plate 128 for storing ice cubes is larger, and the ice guide plate 128 can introduce a larger amount of ice cubes at a time, thereby improving the ice cube transportation efficiency and making it more convenient for users to use.

The ice discharging screw 13 rotates under the drive of the driving member 14 and drives the ice cubes to move to the ice outlet 1291, wherein the ice outlet 1291 is open toward the plane where the bottom plate 122 is located. After the ice cubes move to the ice outlet 1291, they automatically fall, which is convenient for users to use the ice cubes. The position of the ice outlet 1291 is located at the top of the ice discharging ramp to prevent ice cubes from accidentally falling from the ice outlet 1291, and it is convenient for users to place containers containing ice cubes under the ice outlet 1291, which is convenient for users to use.

[0083] According to one embodiment of the present invention, a matching hole is formed on the second mounting plate 129, and the driving member 14 is arranged on the side of the second mounting plate 129 away from the ice discharge ramp.

[0084] Specifically, a matching hole is formed on the second mounting plate 129, and the penetration direction of the matching hole is the same as the extension direction of the ramp plate 123, which facilitates the connection of the other end of the ice-discharging screw 13 with the driving member 14. The driving member 14 is arranged on the side of the second mounting plate 129 away from the ice-discharging ramp. The driving member 14 can be constructed as a driving motor. The output shaft of the driving member 14 extends to the matching hole and is connected to the other end of the ice-discharging screw 13 through a connecting sleeve to ensure that the ice-discharging screw 13 and the output shaft of the driving member 14 are stably connected. The driving member 14 drives the other end of the ice-discharging screw 13 to rotate through the output shaft, thereby driving the ice cubes to move from the bottom of the ice-discharging ramp to the ice outlet 1291, and the ice cubes fall from the ice outlet 1291, which is convenient for users to use.

[0085] According to one embodiment of the present invention, the ice discharging mechanism 1 further includes a rotating support 15 rotatably disposed on the first mounting plate 121 and connected to one end of the ice discharging screw 13 to support the rotation of the ice discharging screw 13 .

[0086] Specifically, a rotating support 15 is rotatably provided on the first mounting plate 121. The rotating support 15 can be constructed as a bearing. One end of the ice-out screw 13 is fixedly connected to the rotating support 15, thereby supporting the ice-out screw 13 to rotate under the drive of the driving member 14, avoiding the collision of one end of the ice-out screw 13 with the first mounting plate 121 during the rotation of the ice-out screw 13, causing damage to the first mounting plate 121, extending the service life of the first mounting plate 121, and ensuring that the rotation of the ice-out screw 13 is smoother, thereby improving the ice-out efficiency.

[0087] In some embodiments, the ice discharging mechanism 1 is connected to the ice making module, and the ice making module includes an ice making bin, in which an ice making part and an ice shoveling part 41 are provided. The ice shoveling part 41 is movably provided in the ice making bin, and the ice shoveling part 41 is suitable for shoveling the ice cubes formed in the ice making bin into the ice discharging shell 12 through the ice guide plate 128.

[0088] Among them, the ice making part can produce ice cubes. When the ice cubes are formed, the ice cubes are large in size and can fall from the ice making part. The fallen ice cubes are scooped out by the ice scooping part 41. The ice scooping part 41 moves and shovels the ice cubes along the ice guide plate 128 into the ice outlet shell 12 for storage. When the user needs it, it can be taken out in real time, which is convenient for the user to use.

[0089] To sum up, the ice-discharging mechanism 1 according to the present invention includes a shell 11, an ice-discharging shell 12, an ice-discharging screw 13 and a driving member 14. A accommodating chamber and an ice-discharging port 1291 connected to the accommodating chamber are formed in the shell 11. The ice-discharging shell 12 and the ice-discharging screw 13 are both arranged in the accommodating chamber. One end of the ice-discharging screw 13 is arranged at one end of the ice-discharging shell 12, and the other end of the ice-discharging screw 13 spirally extends to the ice-discharging port 1291. A tilted ice-discharging ramp is formed on the ice-discharging shell 12, and the ice-discharging port 1291 is arranged at the top of the ice-discharging ramp to raise the height of the ice-discharging port 1291 to prevent ice cubes from accidentally falling and to facilitate users to take ice.

[0090] The ice discharging shell 12 includes a first mounting plate 121, a bottom plate 122 and a ramp plate 123. One end of the ice discharging screw 13 is fixedly mounted on the first mounting plate 121. The bottom plate 122 is arranged at the bottom of the first mounting plate 121. One end of the ramp plate 123 is connected to the bottom plate 122. An ice discharging ramp is formed on the ramp plate 123 and extends obliquely relative to the bottom plate 122 to the ice discharging port 1291. The other end of the ice discharging screw 13 spirally extends to the ice discharging port 1291. The ice discharging screw 13 rotates under the drive of the driving member 14 and drives the ice cubes to move along the ice discharging ramp to the ice discharging port 1291. The ice discharging shell 12 also includes a first side wall 124, a second side wall 125 and a third side wall 126. The first side wall 124, the second side wall 125 and the third side wall 126 are respectively inclined relative to the bottom plate 122 to The ice cubes in the ice box are guided to the bottom of the ramp plate 123 to prevent the ice cubes from accumulating on the ramp plate 123 and affecting the ice discharging efficiency. A connecting hole 127 is formed on the ramp plate 123 to return the cold water generated by the melting of the ice cubes to the cold water tank 16 at the bottom of the ramp plate 123, providing cold water for the user and slowing down the melting speed of the ice cubes; the ice discharging shell 12 also includes a second mounting plate 129, and the driving member 14 is arranged on the second mounting plate 129. A matching hole is formed on the second mounting plate 129. The output end of the driving member 14 extends to the matching hole and is matched with the other end of the ice discharging screw 13 to facilitate driving the ice discharging screw 13 to rotate. An ice discharging port 1291 is formed on the second mounting plate 129. The driving member 14 drives the ice discharging screw 13 to rotate, so as to drive the ice cubes to move along the ice discharging ramp to the ice discharging port 1291, making it convenient for users to take ice.

[0091] The following briefly describes the control method for the ice discharging mechanism 1 according to the present invention.

[0092] The control method for the ice discharging mechanism 1 according to the present invention includes: after receiving the ice discharging instruction, controlling the driving member 14 to drive the ice discharging screw 13 to rotate in the ice discharging direction, and after each rotation for a preset time t1, the driving member 14 drives the ice discharging screw 13 to rotate in the ice defrosting direction for a preset time t2.

[0093] Specifically, after the user presses the ice discharging button, the ice discharging mechanism 1 sends an ice discharging instruction. After receiving the ice discharging instruction, the ice discharging mechanism 1 controls the driving member 14 to start, and the driving member 14 electrically drives the ice discharging screw 13 to rotate in the ice discharging direction, wherein the ice discharging direction can be clockwise, and the rotation of the ice discharging screw 13 in the ice discharging direction is positive rotation. After the ice discharging screw 13 rotates in the ice discharging direction for a preset time t1, it drives the ice cubes to move along the ice discharging ramp to the ice discharging port 1291, and then the ice discharging screw 13 rotates in the ice-defrosting direction under the drive of the driving member 14, wherein the ice-defrosting direction can be counterclockwise. , that is, reverse rotation, the ice-discharging screw 13 rotates in the ice-defrosting direction and drives the ice cubes to be discharged from the ice outlet 1291 to provide the ice cubes to the user. The ice-discharging screw 13 rotates in the ice-defrosting direction for a preset time t2 and then rotates in the ice-discharging direction. Driven by the driving member 14, the ice-discharging screw 13 repeats the alternating rotation of forward rotation and reverse rotation to prevent ice cubes from accumulating at the ice outlet 1291. An ice-discharging door can be provided at the ice outlet 1291. When the user needs to use ice cubes, the ice-discharging door is opened for the user to take ice. When the user finishes taking ice, the ice-discharging door is closed to prevent ice cubes from falling.

[0094] According to one embodiment of the present invention, t1 and t2 satisfy: 1 / 8≤t2 / t1≤1 / 4.

[0095] Specifically, the ratio t2 / t1 of the preset time t2 of the ice-discharging screw 13 rotating in the ice-defrosting direction to the preset time t1 of the ice-discharging screw 13 rotating in the ice-discharging direction can be set to 1 / 8, 1 / 6, 1 / 4, etc., wherein the rotation time of the ice-discharging screw 13 in the ice-discharging direction is greater than the rotation time of the ice-discharging screw 13 in the ice-defrosting direction. In the process of rotating in the ice-discharging direction, the ice cubes are driven to move along the ice-discharging ramp to the ice outlet 1291. The rotation of the ice-discharging screw 13 in the ice-defrosting direction drives the ice cubes to be discharged from the ice outlet 1291 and breaks up the ice cubes discharged from the ice outlet 1291 to prevent the ice cubes from accumulating at the ice outlet 1291 and affecting the discharge efficiency of the ice cubes. The ice-discharging screw 13 rotates alternately in the ice-discharging direction and the ice-defrosting direction to ensure that the ice cubes are discharged in an orderly manner, which is convenient for users.

[0096] According to one embodiment of the present invention, after receiving the ice-discharging instruction, the driving member 14 drives the ice-discharging screw 13 to rotate in the ice-removing direction for a preset time t3.

[0097] Specifically, when the user presses the ice-discharging button, an ice-discharging instruction is sent to the ice-discharging mechanism 1. The driving member 14 starts and drives the ice-discharging screw 13 to rotate in the ice-removing direction for a preset time t3, stirring the ice-discharging ramp and the ice-discharging port 1291 to loosen the ice cubes, prevent ice cubes from accumulating, and ensure that the ice cubes can be discharged smoothly from the ice-discharging port 1291, which is convenient for users to use.

[0098] According to one embodiment of the present invention, after receiving the ice discharging end instruction, the driving member 14 drives the ice discharging screw 13 to rotate in the ice-removing direction for a preset time t4.

[0099] Specifically, when the user stops taking ice and issues an ice discharging end instruction to the ice discharging mechanism 1, the driving member 14 receives the ice discharging end instruction and drives the ice discharging screw 13 to rotate in the ice-deflation direction for a preset time t4, thereby breaking up the ice cubes in the ice outlet 1291 and preventing the ice cubes from accumulating in the ice outlet 1291 and affecting the closing of the ice outlet 1291. After the ice discharging screw 13 rotates in the ice-deflation direction for a preset time t4, the ice discharging mechanism 1 stops discharging ice, the driving member 14 is closed, and the ice discharging screw 13 stops rotating.
