Description

Technical Field

[0001] The invention relates to the field of refrigeration equipment, and in particular to a control method for an ice-making mechanism. Background Art

[0002] For existing refrigeration equipment with ice-making function, the ice-making machine is usually arranged in a freezing door or a box to make ice according to user needs. An ice storage box is arranged at the bottom of the ice-making machine to store ice cubes, which can be taken at any time when the user needs to take them.

[0003] For ice makers in existing refrigeration equipment, an ice detection plate is used to detect whether the ice storage box is full of ice before each ice turning. When the ice detection plate detects that the ice is not full, the ice cubes in the ice mold need to be discharged. When discharging, the ice detection plate needs to be retracted to the bottom of the ice maker to prevent the discharged ice cubes from falling onto the ice detection plate and causing quality problems.

[0004] In the prior art, ice can only be detected when the ice detection plate rotates toward the front side of the ice tray. When the ice maker is deicing, the ice detection plate cannot detect ice when it is recovered to the bottom of the ice maker. Summary of the invention

[0005] The object of the present invention is to provide a control method for an ice-making mechanism to solve the above-mentioned problem.

[0006] To achieve one of the above-mentioned objects, the present invention provides a control method for an ice-making mechanism, the ice-making mechanism comprising an ice tray, an ice storage box located at the lower side of the ice tray, an ice detection assembly for detecting whether the ice storage box is full of ice, and an ice pushing assembly for pushing ice cubes in the ice tray into the ice storage box, the ice detection assembly comprising an ice detection plate located in the ice storage box, and a driving assembly for driving the ice detection plate to rotate, the control method comprising the following steps: before the ice pushing assembly pushes ice, the ice detection plate rotates from an initial position toward the lower side of the ice tray, and if the ice detection plate encounters an obstacle during the process of rotating toward the lower side of the ice tray, it is determined that the ice storage box is full of ice.

[0007] As a further improvement of the present invention, after the ice detecting plate encounters an obstacle during the process of rotating toward the lower side of the ice making tray, the ice detecting plate is reset to an initial position.

[0008] As a further improvement of the present invention, after the ice detecting plate rotates toward the lower side of the ice making tray to a first preset position located at the lower side of the ice making tray, the ice pushing assembly pushes the ice.

[0009] As a further improvement of the present invention, after pushing the ice, the ice detection plate rotates from the first preset position to the initial position to detect ice. If the ice detection plate encounters an obstacle during the ice detection process, it is determined that the ice storage box is full of ice.

[0010] As a further improvement of the present invention, the ice detection assembly also includes a transmission rod connected to the drive assembly and extending downward, the transmission rod includes an upper transmission rod connected to the drive assembly, a lower transmission rod circumferentially movably connected to the upper transmission rod, and an elastic member located between the upper transmission rod and the lower transmission rod.

[0011] As a further improvement of the present invention, the driving assembly includes a horizontally arranged rotating shaft, a driving member for driving the rotating shaft to rotate, and a conversion component connected to the transmission rod, wherein the conversion component is used to convert the horizontal axial rotation of the rotating shaft into the vertical axial rotation of the transmission rod; the ice pushing assembly includes a horizontally arranged ice pushing rod, and the ice pushing rod is fixedly connected to the rotating shaft.

[0012] As a further improvement of the present invention, the ice pushing assembly also includes a plurality of ice pushing parts arranged at intervals along the axial direction of the ice pushing rod; the ice making tray has ice discharge ports arranged one by one corresponding to the ice pushing parts; when the ice detecting plate is in the initial position, the ice pushing assembly is in a starting position where the ice pushing part and the ice discharge port form a preset angle.

[0013] As a further improvement of the present invention, the preset angle is specifically that the ice pushing portion and the ice discharge port form an angle of 80°.

[0014] As a further improvement of the present invention, after the ice detecting plate encounters an obstacle during the process of rotating toward the lower side of the ice making tray, the ice detecting plate is reset to an initial position, and at the same time, the ice pushing assembly is also reset to a starting position.

[0015] As a further improvement of the present invention, the ice-making mechanism is further provided with an ice-pushing assembly detector, and the ice-pushing assembly detector is used to determine the state of the ice-pushing assembly.

[0016] In the ice-making mechanism of the present invention, before the ice pushing assembly pushes ice, the ice detecting plate rotates from an initial position toward the lower side of the ice making tray. If the ice detecting plate encounters an obstacle during the process of rotating toward the lower side of the ice making tray, it is determined that the ice storage box is full of ice, thereby realizing ice detection in the direction of rotation of the ice detecting plate in the ice detecting assembly toward the lower side of the ice making tray, thereby improving the accuracy of ice detection.

[0024] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0025] It should be understood that the terms used herein, such as "upper", "lower", "inner", "front", etc., indicating spatial relative positions are used for the purpose of convenience to describe the relationship of one component or feature relative to another component or feature as shown in the drawings. The terms of spatial relative positions may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0026] See also Figures 1 to 6 As shown, the present invention provides an ice-making mechanism 100, comprising an ice tray 1, an ice storage box located at the lower side of the ice tray 1, and an ice detection assembly for detecting whether the ice storage box is full of ice, wherein the ice detection assembly comprises a driving assembly fixed to the ice tray 1, a transmission rod 3 connected to the driving assembly and extending downward, and an ice detection plate 4 connected to the lower end of the transmission rod 3 and used to detect the amount of ice in the ice storage box, wherein the transmission rod 3 comprises an upper transmission rod 31 connected to the driving assembly, a lower transmission rod 32 circumferentially movably connected to the upper transmission rod 31, and an elastic member 33 located between the upper transmission rod 31 and the lower transmission rod 32. When the ice detection plate 4 encounters interference from ice cubes or other obstacles during the process of being recovered to the bottom of the ice tray 1, since the elastic member 33 is arranged between the upper transmission rod 31 and the lower transmission rod 32 that drive the ice detection plate 4 to rotate, the elastic member 33 buffers the resistance applied to the ice detection plate 4 by the obstacles, thereby avoiding the problem of interference fracture of the ice detection plate 4.

[0027] It can be understood that the ice detection plate 4 can be fixedly connected to the lower transmission rod 32, and the driving assembly can drive the transmission rod 3 to drive the ice detection plate 4 to reciprocate horizontally. When the ice detection assembly is in the process of detecting ice, the ice detection plate 4 rotates away from the ice tray 1; when the ice tray 1 is detached, the ice detection assembly is in the process of recovering ice, and the ice detection plate 4 rotates toward the lower side of the ice tray 1.

[0028] In the present invention, due to the structural setting of the transmission rod 3, the ice tray 1 can shed ice while the ice detection plate 4 rotates toward the lower side of the ice tray 1. When the ice detection plate 4 touches an obstacle, the ice detection plate 4 stops rotating and the ice tray 1 continues to shed ice. The ice-making mechanism 100 in the present invention can ensure that the ice detection plate 4 will not break when encountering an obstacle in the recovery state, and at the same time will not affect the de-icing process of the ice tray 1.

[0029] Further, one of the lower end of the upper transmission rod 31 and the upper end of the lower transmission rod 32 is recessed with a matching groove 34, and the other is located in the matching groove 34. The elastic member 33 is located in the matching groove 34, and the elastic member 33 is a first torsion spring sleeved on the upper transmission rod 31 or the lower transmission rod 32 located in the matching groove 34, and one end of the first torsion spring is connected to the upper transmission rod 31, and the other end is connected to the lower transmission rod 32. When the ice-making mechanism 100 is de-icing, when the ice-detecting plate 4 encounters ice cubes or other obstacles during the process of being recovered to the bottom of the ice tray 1, a first torsion spring is arranged between the upper transmission rod 31 and the lower transmission rod 32, and the first torsion spring is used to buffer the resistance applied to the ice-detecting plate 4 by the obstacles, and the upper transmission rod 31 and the lower transmission rod 32 are rotated separately, thereby avoiding the problem of interference and fracture of the ice-detecting plate 4.

[0030] In a specific embodiment, a matching groove 34 is provided at the lower end of the upper transmission rod 31, and correspondingly, the upper end of the lower transmission rod 32 is located in the matching groove 34, and a first torsion spring is sleeved on the upper end of the lower transmission rod 32, and one end of the first torsion spring is connected to the upper transmission rod 31, and the other end is connected to the lower transmission rod 32. The axial limit between the upper transmission rod 31 and the lower transmission rod 32 is achieved by the matching of the matching groove 34 and the upper end of the lower transmission rod 32, and the circumferential connection between the upper transmission rod and the lower transmission rod 32 is achieved by the first torsion spring, so that when the driving assembly drives the upper transmission rod 31 to rotate, the upper transmission rod 31 can drive the lower transmission rod 32 to rotate, and the ice detection plate 4 is fixedly connected to the lower transmission rod 32, and finally the driving assembly drives the ice detection plate 4 to rotate horizontally. It is understandable that when the ice tray 1 is detached from ice, the driving assembly drives the upper transmission rod 31 to rotate, so that the ice detection plate 4 rotates toward the lower side of the ice tray 1. During the rotation of the ice detection plate 4, if the ice detection plate 4 encounters an obstacle and is subjected to resistance, the resistance will be transmitted to the lower transmission rod 32. The present invention buffers the resistance of the lower transmission rod 32 and the ice detection plate 4 by providing a first torsion spring simultaneously with the upper transmission rod 31 and the lower transmission rod 32, and when the driving assembly drives the upper transmission rod 31 to rotate and the ice detection plate 4 encounters an obstacle, the upper transmission rod 31 and the lower transmission rod 32 are rotated separately, thereby avoiding the problem of interference fracture of the ice detection plate 4.

[0031] For further information, see Figure 4 As shown, one of the lower end of the upper transmission rod 31 and the upper end of the lower transmission rod 32 is recessed with a matching groove 34, and the other is convexly provided with a positioning column 35 located in the matching groove 34. The first torsion spring is sleeved on the positioning column 35 and is arranged between the positioning column 35 and the matching groove 34. The axial limitation between the upper transmission rod 31 and the lower transmission rod 32 is better guaranteed by the cooperation between the matching groove 34 and the positioning column 35. When the transmission rod 3 is assembled, it is convenient to position the upper transmission rod 31 and the lower transmission rod 32, thereby simplifying the installation process of the transmission rod 3.

[0032] Furthermore, the ice-making mechanism 100 also includes a first annular wall 36 arranged on the outside of the matching groove 34, and a second annular wall 37 arranged on the outside of the positioning column 35. The diameter of the first annular wall 36 is smaller than the diameter of the second annular wall 37. An accommodating portion is formed between the second annular wall 37 and the positioning column 35. The first annular wall 36 is located in the accommodating portion to achieve circumferential limitation of the upper transmission rod 31 and the lower transmission rod 32.

[0033] For further information, see Figure 5 and Figure 6As shown, a protruding portion 38 is convexly provided on the end surface of the matching groove 34; a stopper 39 is convexly provided on the outer peripheral surface of the positioning column 35, and the stopper 39 is located on the rotation side of the protruding portion 38. When the protruding portion 38 rotates to abut against the stopper 39, the stopper 39 plays a limiting role. Of course, it can be understood that the number of the protruding portions 38 can be set to multiple, and the number of the stopper 39 is the same as the number of the protruding portions 38, and they are set one by one.

[0034] Furthermore, the ice tray 1 includes an ice tray body 11 and a support frame 12, and the transmission rod 3 is rotatably connected to the support frame 12; the ice-making mechanism 100 also includes a second torsion spring 5 sleeved on the lower transmission rod 32, one end of the second torsion spring 5 is connected to the support frame 12, and the other end is connected to the ice detection plate 4, and the second torsion spring 5 can quickly drive the ice detection plate 4 to rotate in a direction away from the ice tray 1.

[0035] It is understandable that, in the present invention, the ice detection plate 4 has an initial position, which is a preset position of the ice detection plate 4 located in front of the ice tray 1. The present invention can quickly return the ice detection plate 4 to the initial position after the ice tray 1 is detached by providing the second torsion spring 5.

[0036] Furthermore, the distance between two adjacent coils of the first torsion spring is smaller than the distance between two adjacent coils of the second torsion spring 5, so that the torsion of the first torsion spring is greater than the torsion of the second torsion spring 5, ensuring that when the ice tray 1 is detached from ice, the first torsion spring can overcome the torsion of the second torsion spring 5, drive the lower transmission rod 32 and the ice detection plate 4 to rotate, and realize the rotation of the ice detection plate 4 toward the lower side of the ice tray 1. Of course, it can be understood that the setting mode in which the torsion of the first torsion spring is greater than the torsion of the second torsion spring 5 is not limited to this.

[0037] In a specific embodiment of the present invention, the driving assembly includes a horizontally arranged rotating shaft, a driving member for driving the rotating shaft to rotate, and a conversion component connected to the transmission rod 3, wherein the conversion component is used to convert the horizontal axial rotation of the rotating shaft into the vertical axial rotation of the transmission rod 3.

[0038] For further information, see Figure 2 As shown, Figure 2Part of the ice tray body 11 is hidden, and the ice making mechanism 100 also includes an ice pushing assembly 6 arranged on the upper side of the ice tray 1, and the ice pushing assembly 6 includes a horizontally arranged ice pushing rod 61, and the ice pushing rod 61 is fixedly connected to the rotating shaft, so that the driving assembly drives the ice detection plate 4 to rotate while driving the ice pushing rod 61 to rotate, thereby realizing the linkage between the ice pushing assembly 6 and the ice detection assembly, ensuring that when the ice pushing rod 61 pushes ice, the ice detection plate 4 rotates toward the lower side of the ice tray 1 to realize ice detachment of the ice tray 1; at the same time, when the ice pushing rod 61 pushes ice and the ice detection plate 4 encounters an obstacle during the rotation process, the ice detection plate 4 can stop rotating, and the ice pushing rod 61 continues to push ice to avoid the ice detection plate 4 from breaking, and at the same time, it can ensure that the ice tray 1 detaches normally.

[0039] Furthermore, the ice detection plate 4 is in the shape of an elongated rod. When the ice detection plate 4 stops rotating and the ice pushing rod 61 continues to push ice, ice cubes falling off the ice tray 1 will not fall onto the ice detection plate 4, further ensuring normal deicing of the ice tray 1.

[0040] Another aspect of the present invention further provides a control method for an ice-making machine. The specific structure of the ice-making mechanism is as described above and will not be described in detail herein.

[0041] See also Figure 7 As shown, the control method comprises the following steps:

[0042] S1: Before the ice pushing assembly pushes ice, the ice detecting plate rotates from an initial position toward the lower side of the ice making tray. If the ice detecting plate encounters an obstacle during the rotation toward the lower side of the ice making tray, it is determined that the ice storage box is full of ice.

[0043] In the present invention, the ice detection plate has an initial position, which is a preset position of the ice detection plate in front of the ice tray. Before the ice pushing assembly pushes ice, if the ice detection plate encounters an obstacle during the rotation process toward the lower side of the ice tray, it is determined that the ice storage box is full of ice, thereby realizing ice detection in the direction of rotation of the ice detection plate in the ice detection assembly toward the lower side of the ice tray, thereby improving ice detection accuracy.

[0044] Of course, it is understandable that the ice-making mechanism is provided with an ice-detecting plate detector for detecting whether the ice-detecting plate encounters an obstacle during the rotation process. Specifically, when the ice-detecting plate encounters an obstacle during the rotation process, the ice-detecting plate detector senses that the ice-detecting plate stops, and then feeds back the result to the controller in the ice-making mechanism, and the controller controls the ice-pushing assembly not to push ice, thereby avoiding the problem that too much ice cubes in the ice storage box cannot be stored.

[0045] Furthermore, the ice-making mechanism is also provided with an ice-pushing assembly detector, and the ice-pushing assembly detector is used to determine the state of the ice-pushing assembly. It is understandable that the ice-pushing assembly includes a horizontally arranged ice-pushing rod, and the ice-pushing assembly detector can determine the state of the ice-pushing assembly by the actual number of revolutions of the ice-pushing rod. Specifically, the ice-pushing assembly includes a variety of states, such as before pushing ice, during pushing ice, and completed pushing ice, and each state corresponds to a different rotation range of the ice-pushing rod. By detecting the actual number of revolutions of the ice-pushing rod, the state of the ice-pushing assembly can be determined according to the corresponding rotation range.

[0046] In the present invention, the ice detection assembly further includes a transmission rod connected to the driving assembly and extending downward, and the transmission rod includes an upper transmission rod connected to the driving assembly, a lower transmission rod circumferentially movably connected to the upper transmission rod, and an elastic member located between the upper transmission rod and the lower transmission rod. When the ice detection plate encounters interference from ice cubes or other obstacles during the process of being recovered to the bottom of the ice tray, since an elastic member is provided between the upper transmission rod and the lower transmission rod that drive the ice detection plate to rotate, the elastic member buffers the resistance applied to the ice detection plate by the obstacle, thereby avoiding the problem of interference fracture of the ice detection plate.

[0047] Furthermore, the control method further includes:

[0048] S2: When the ice detection plate encounters an obstacle during the process of rotating toward the lower side of the ice tray, the ice detection plate is reset to the initial position.

[0049] The ice detection plate is reset to its initial position after encountering an obstacle, so as to avoid the ice detection plate being in a stress state of being against the obstacle all the time.

[0050] Furthermore, the control method further includes:

[0051] S3: After the ice detecting plate rotates toward the lower side of the ice tray to a first preset position located at the lower side of the ice tray, the ice pushing assembly pushes ice.

[0052] It can be understood that the first preset position of the ice detecting plate at the lower side of the ice tray represents that the ice detecting plate encounters no obstacles during the rotation toward the lower side of the ice tray, and then it can be determined that the ice storage box is not full of ice, and then the ice pushing assembly is controlled to push the ice to store the ice cubes in the ice tray into the ice storage box.

[0053] Furthermore, after step S3, the control method further includes:

[0054] S4: After pushing the ice, the ice detection plate rotates from the first preset position to the initial position to detect ice. If the ice detection plate encounters an obstacle during the ice detection process, it is determined that the ice storage box is full of ice.

[0055] The present invention detects ice after pushing ice. If the ice detection plate detects that the ice storage box is full of ice, the next ice making or ice turning is suspended, thereby avoiding the problem of ice overflowing or sticking due to too much ice in the ice storage box. In addition, the present invention can detect ice when the ice detection plate rotates toward the lower side of the ice tray and when the ice detection plate rotates from the first preset position to the initial position, thereby realizing two-way ice detection of the ice detection component, avoiding the problem of ice overflowing or sticking due to too much ice in the ice storage box.

[0056] In a specific embodiment of the present invention, the driving assembly includes a horizontally arranged rotating shaft, a driving member driving the rotating shaft to rotate, and a conversion component connected to the transmission rod, wherein the conversion component is used to convert the horizontal axial rotation of the rotating shaft into the vertical axial rotation of the transmission rod; the ice-pushing assembly includes a horizontally arranged ice-pushing rod, and the ice-pushing rod is fixedly connected to the rotating shaft, so that the driving assembly simultaneously drives the ice-pushing rod to rotate along the horizontal axis and the ice-detecting plate to rotate along the vertical axis, thereby realizing the linkage of the ice-pushing assembly and the ice-detecting assembly. It is ensured that when the ice-pushing rod pushes ice, the ice-detecting plate rotates toward the lower side of the ice tray to realize ice removal of the ice tray.

[0057] Furthermore, the ice pushing assembly also includes a plurality of ice pushing parts arranged at intervals along the axial direction of the ice pushing rod; the ice making tray has ice discharge ports arranged one-to-one corresponding to the ice pushing parts; when the ice detecting plate is in the initial position, the ice pushing assembly is in a starting position where the ice pushing part and the ice discharge port form a preset angle.

[0058] The control method comprises:

[0059] S5: After the ice pushing is completed, the ice pushing assembly is reset to the starting position.

[0060] It is understandable that when the ice pushing assembly and the ice detecting assembly are linked, after pushing ice, the ice detecting plate rotates from the first preset position to the initial position to detect ice, and the ice pushing assembly resets to the starting position. Specifically, if the direction of rotation of the ice pushing rod when pushing ice is forward, the ice pushing assembly resets to the starting position when the ice pushing rod rotates in the reverse direction to the starting position.

[0061] In a specific embodiment, the preset angle is specifically an angle of 80° between the ice pushing portion and the ice discharge port. The ice detection plate is rotated from the initial position to the lower side of the ice tray. When the ice detection plate encounters an obstacle during the rotation to the lower side of the ice tray, the ice pushing assembly has not yet rotated to the ice pushing position, thereby preventing the ice pushing assembly from pushing ice when the ice storage box is full.

[0062] Furthermore, the control method comprises:

[0063] S6: When the ice detection plate encounters an obstacle during the rotation toward the lower side of the ice tray, the ice detection plate is reset to the initial position, and the ice pushing assembly is also reset to the starting position.

[0064] When the ice pushing assembly and the ice detecting assembly are linked, when the ice pushing rod pushes ice and the ice detecting plate encounters an obstacle during rotation, the ice detecting plate resets to its initial position and the ice pushing assembly also resets to its starting position, to avoid the ice detecting plate being under stress all the time and to prepare for the ice pushing assembly on the next side to push ice after the full ice state of the ice storage box is released.

[0065] In the ice-making mechanism of the present invention, when the ice-detecting plate encounters interference from ice cubes or other obstacles during the process of being recovered to the bottom of the ice tray, an elastic member is provided between the upper transmission rod and the lower transmission rod that drive the ice-detecting plate to rotate, and the elastic member buffers the resistance applied to the ice-detecting plate by the obstacle, thereby avoiding the problem of interference and fracture of the ice-detecting plate. Before the ice-pushing assembly pushes ice, the ice-detecting plate rotates from the initial position toward the lower side of the ice tray. If the ice-detecting plate encounters an obstacle during the process of rotating toward the lower side of the ice tray, it is determined that the ice storage box is full of ice, thereby realizing ice detection in the direction of rotation of the ice-detecting plate in the ice-detecting assembly toward the lower side of the ice tray, thereby improving the accuracy of ice detection.

[0066] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0067] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
