Description

Technical Field

[0001] The present application relates to the technical field of ice making control, and in particular to an ice-shedding control method, a controller and an ice-making machine. Background Art

[0002] Ice makers cool water and freeze it, creating the desired ice cubes. In addition to traditional ice cube makers, recent years have seen the emergence of ice makers for making bullet ice. These ice cubes are typically hollow cylindrical or blind-hole cylindrical, and are very popular with users.

[0003] Bullet Ice's ice maker includes a columnar ice coil. The head of the columnar ice coil freezes the water it touches into ice, and then the ice is removed by heating the head of the columnar ice coil, causing the ice cubes to fall off. However, when the water temperature is low, the ice making speed of the ice maker is faster, and it is easy to over-make ice, causing too much and too large ice on the head of the columnar ice coil, or even the ice cubes to be unable to separate from the columnar ice coil. At this time, the ice maker has difficulty pushing the ice cubes into the ice storage bin, resulting in ice jam. The ice maker cannot resolve the fault by itself at this time, causing trouble for users. Summary of the Invention

[0006] In some embodiments, when it is detected that the flip water tank has not been rotated to the correct position, before issuing an ice stuck prompt, the ice removal control method further includes: Controlling the flip water tank to perform a preset number of reset actions; When the reset action of the preset number of times fails to rotate the flip water tank to the correct position, it is confirmed that the flip water tank has a flip abnormal failure.

[0007] In some embodiments, the resetting action includes: Controlling the flip water tank to rotate to the first angle; Controlling the flip water tank to rotate to the second angle and detecting whether it is fully rotated; When it is detected that the flip water tank fails to rotate to the correct position, it is determined that an abnormal flip failure occurs in the reset action.

[0008] In some embodiments, the ice maker includes a flip motor, and the output shaft of the flip motor is connected to the flip water tank; controlling the flip water tank to rotate to the second angle and detecting whether it is rotated to the desired angle includes: sending a rotation instruction to the flip motor to instruct the flip motor to output a rotation action corresponding to the second angle; receiving angle feedback information returned by the flip motor after executing the rotation instruction; Whether the rotation is in place is determined based on the magnitude relationship between the actual rotation angle indicated by the angle feedback information and the second angle.

[0009] In some embodiments, the de-icing control method further includes: In response to an ice-making instruction, controlling the columnar ice-making coil to refrigerate, and recording ice-making time and ice-making power; The step of controlling the columnar ice making tray to melt ice comprises: Determining an ice melting time and / or an ice melting power according to the ice making time and the ice making power; The heating of the columnar ice making tray is controlled according to the ice melting time and / or the ice melting power.

[0011] In some embodiments, the ice maker further includes a compressor, a heat exchanger, and a throttle. When the ice maker is in ice-making operation, the compressor, the heat exchanger, the throttle valve, and the columnar ice-making coil are connected in sequence to form an ice-making circuit. When the ice maker is in ice-defrosting operation, the compressor and the columnar ice-making coil are connected to form a heating circuit.

[0012] In some embodiments, the ice maker further includes an on-off valve, through which the exhaust port of the compressor is connected to the columnar ice-making coil. When the on-off valve is open, the compressor and the columnar ice-making coil form the heating circuit.

When shedding ice, the water tank is turned over and rotated to a first angle to form a cavity for temporarily loading ice cubes, and the columnar ice-making tray pipe is controlled to heat so that the ice cubes on the column head fall off. Then, the water tank is turned over and rotated to a second angle again. When the second angle is fully rotated, the ice cubes can be pushed out smoothly. If the water tank fails to be fully rotated after being rotated to the second angle, it is determined that ice is stuck. In addition to issuing an ice stuck prompt, the columnar ice tray pipe can also be controlled to heat and melt the ice to solve the ice stuck problem by itself. Therefore, the ice maker of the embodiment of the present application can determine the ice stuck problem by turning the water tank over and solve the ice stuck problem by melting the ice when ice stuck occurs, thereby avoiding the ice maker from being stuck and unable to execute subsequent instructions, and also saving the user the trouble of handling ice stuck by themselves.

[0021] Home ice makers are primarily used to quickly produce ice cubes. Compared to traditional refrigerator freezers that produce cubed ice, ice makers can produce a certain amount of ice in just minutes. Depending on the production method, ice cubes can be made in different shapes to meet diverse user needs. Currently, a common home ice maker can produce bullet ice, which has a sleek appearance and is more attractive to consumers than traditional cube ice. Bullet ice machines feature an evaporator with a cylindrical ice coil. During ice making, the coil absorbs heat from the water on the surface to form cylindrical ice cubes. Since ice cubes adhere to the caps of the coils, defrosting is necessary to remove the ice from the caps. This process heats the caps, melting the ice at the contact surface with the ice cubes, creating a mixture of ice and water. The ice then falls due to gravity, completing the defrosting process.

[0022] The ice making and de-icing processes of the current ice maker require controlling the rotation of the flip water tank. When making ice, the flip water tank is rotated so that its opening faces upward, so that the column head of the columnar ice-making coil is located inside the flip water tank, and water required for ice making is introduced into the flip water tank so that the water level covers the column head of the columnar ice-making coil, and then the columnar ice-making coil is refrigerated, so that bullet ice is formed at the column head of the columnar ice-making coil; when de-icing, the flip water tank is rotated so that it is rotated to a certain angle, and the water in the flip water tank is poured out back to the water storage bin. At this time, there is a baffle under the columnar ice-making coil, and the baffle and its adjacent side walls form a cavity for temporarily loading ice cubes. At this time, the bullet ice is heated by the columnar ice-making tray and falls into the cavity for temporarily loading ice cubes. Then, the flip water tank is rotated again so that its opening faces upward, and the baffle pushes out the bullet ice in the cavity for temporarily loading ice cubes, so that the bullet ice slides into the ice storage bin on the side, thereby completing an ice making and de-icing process.

[0023] Therefore, it can be seen that the correct rotation of the flip water tank is one of the key points in ice making and ice removal. When the water temperature is low, the ice making speed of the ice maker is relatively fast, which can easily lead to excessive ice making, resulting in excessive and large ice at the head of the columnar ice making coil, and even the ice cubes cannot be separated from the columnar ice making coil. After ice making is completed, although the flip water tank can rotate correctly to return the water to the water storage tank, during the ice removal process, the excessive and large ice cubes prevent the baffle from pushing the ice cubes, resulting in ice jam. Currently, ice makers have no self-resolving solution for ice jams and can only prompt users to handle it. If users handle it themselves, they need to wait for the ice cubes to melt or manually break the ice cubes, which is obviously inconvenient and troublesome for users.

[0024] Based on this, the embodiment of the present application provides an ice-defrosting control method, a controller and an ice-making machine for an ice maker, which controls the rotation of the flip water tank during the defrosting process, and uses the rotation angle of the flip water tank to determine whether ice is stuck. When ice is stuck, in addition to issuing an ice jam prompt, it can also control the heating of the columnar ice-making coil to melt the ice cubes, solve the ice jam problem by itself, and help users solve ice jam problems.

[0025] The following describes the de-icing control method, controller and ice maker of the ice maker with reference to the accompanying drawings: Reference Figure 1 As shown, Figure 1This is a schematic diagram of the structure of an ice maker provided in an embodiment of the present application. The ice maker includes a flip water tank 100 and a refrigerant circulation system. The refrigerant circulation system includes a compressor 300, a condenser 400, an evaporator 200 and a capillary tube 500. The exhaust port of the compressor 300 is connected to the inlet of the evaporator 200 through the condenser 400 and the capillary tube 500, and the outlet of the evaporator 200 is connected to the air inlet of the compressor 300, forming a refrigeration circuit. The refrigerant absorbs heat when passing through the evaporator 200; the refrigerant circulation system also includes an on-off valve 600. The exhaust port of the compressor 300 is also directly connected to the inlet of the evaporator 200 through another pipeline. The on-off valve 600 is set in this pipeline to control whether the refrigerant passes through this pipeline. When the on-off valve 600 is open, the high-temperature and high-pressure refrigerant of the compressor 300 can directly enter the evaporator 200 through this pipeline, forming a heating circuit, and the refrigerant releases heat when passing through the evaporator 200. The evaporator 200 includes a columnar ice-making coil 210 . The columnar ice-making coil 210 can absorb heat to make ice through a refrigeration circuit, and can release heat to remove ice through a heating circuit.

[0026] The flip water tank 100 is driven by the flip motor 110. The flip water tank 100 rotates substantially around the evaporator 200. A baffle is provided on the edge of the flip water tank 100. The baffle is connected to the rotating shaft of the flip water tank 100. When the flip water tank 100 rotates to the bottom of the evaporator 200, the opening of the flip water tank 100 faces upward and the column head of the columnar ice making coil 210 is immersed below the horizontal plane in the flip water tank 100, and the baffle is pushed upward. When it reaches the side of the evaporator 200, the opening of the flip water tank 100 is located on the side of the evaporator 200, and the baffle moves with the flip water tank 100 and moves to the bottom of the columnar ice-making coil 210. When de-icing is completed, the flip water tank 100 needs to be rotated back to the position with the opening facing upward. During the rotation process, the baffle moves with the flip water tank 100, and the baffle acts as a shovel to push the de-iced ice cubes upward. At this time, the baffle is an inclined surface, which can make the ice cubes roll down to the ice storage bin on the side.

[0027] It is understandable that the output shaft of the flip motor 110 is connected to one side of the flip water tank 100, and the rotation position / rotation angle of the flip motor 110 can be measured by a motor encoder and fed back to the controller of the ice maker.

[0028] The ice maker also includes a water pump and a water storage tank. The water pump's water inlet is connected to the water storage tank. When ice is to be made, the opening of the inverted water tank 100 is facing upward, and the water pump flows water from the water storage tank into the inverted water tank 100. When ice is to be defrosted, the opening of the inverted water tank 100 is located on the side of the evaporator 200, and the water in the inverted water tank 100 is poured out and returned to the water storage tank.

[0029] Reference Figure 2As shown, the embodiment of the present application provides an ice-removing control method for an ice-making machine, including but not limited to the following steps: Step S210, in response to the de-icing instruction, controlling the flip water tank 100 to rotate to a first angle, and controlling the columnar ice-making coil 210 to heat; Step S220, after the columnar ice-making coil 210 heats for a preset time, the flip water tank 100 is controlled to rotate to a second angle and detects whether it is fully rotated; In step S230, when it is detected that the flip water tank 100 fails to rotate to the right position, an ice stuck prompt is issued and the columnar ice making coil 210 is controlled to heat and melt ice.

[0030] As can be seen from the foregoing, when the ice maker receives a de-icing command, the tilting water tank 100 rotates to a position where its opening is located to the side of the evaporator 200. At this point, the corresponding output angle of the tilting motor 110 is a first angle. When the tilting motor 110 determines that the actual rotation angle of the tilting water tank 100 is the same as the output angle, indicating that the tilting water tank 100 has reached its desired position, the ice maker can control the on-off valve 600 to open, allowing the high-temperature, high-pressure refrigerant from the exhaust port of the compressor 300 to directly enter the evaporator 200 to release heat. At this point, a baffle connected to the tilting water tank 100 via a rotating shaft is located below the columnar ice coil 210 and cooperates with a side panel within the ice maker to form a temporary ice storage cavity. The contact surface between the columnar ice coil 210 and the ice melts, forming an ice-water mixture, which then falls by gravity into the temporary ice storage cavity.

[0031] The ice-removing time is the heating time of the columnar ice-making coil 210. After the compressor 300 runs for a preset time (the preset time can be a fixed value or determined based on the actual operation of the ice-making machine), the ice-making machine determines that sufficient heat has been provided to remove the ice cubes from the columnar ice-making coil 210. The tilting water tank 100 rotates to a position where the opening is facing upward. At this time, the output angle of the tilting motor 110 is the second angle. If no ice is stuck, the tilting motor 110 determines that the actual rotation angle of the tilting water tank 100 is the same as the output angle, both being the second angle. If ice is stuck, the actual rotation angle of the tilting motor 110 is different from the output angle. Based on the angle feedback of the tilting motor 110, the controller of the ice-making machine executes the above-mentioned step S230. That is, if it is determined based on the actual angle that the tilting water tank 100 has not rotated to the desired position, it is determined that ice is stuck in the ice-making machine. The refrigerant circulation system is controlled to operate to form a heating circuit, and the ice is melted by heating the columnar ice-making coil 210, thereby resolving the ice stuck problem. In addition to melting ice on its own, the ice maker also issues an ice jam reminder to remind the user that ice is currently stuck and / or that ice is currently melting.

[0032] Through the above method, the ice jam situation can be judged by flipping the rotation angle of the water tank 100, and the ice jam can be solved by melting the ice when it occurs, thereby avoiding the ice maker from being stuck and unable to execute subsequent instructions, and saving users the trouble of handling ice jams by themselves.

[0033] Reference Figure 3 As shown, in some embodiments, when it is detected that the flip tank 100 fails to rotate to the desired position, before issuing an ice stuck prompt, the ice removal control method further includes: Step S310, controlling the flip tank 100 to perform a preset number of reset actions; In step S320 , when the preset number of reset actions fail to rotate the flip water tank 100 to the correct position, it is determined that the flip water tank 100 has a flipping abnormality.

[0034] To reduce false alarms, the ice maker can rotate the tilting tank 100 multiple times to confirm whether ice is stuck. Specifically, the ice maker can confirm whether the tilting tank 100 is fully rotated by performing a reset action multiple times. The reset action involves rotating the tilting tank 100. If ice is indeed stuck, each reset action will inevitably fail to fully rotate the tilting tank 100. In this case, it can be confirmed that the tilting tank 100 has a rotational abnormality, and the columnar ice-making coil 210 can be controlled to heat and melt the ice. It is understood that the preset number of times is a positive integer, and the reset action can be performed once or multiple times.

[0035] Reference Figure 4 As shown, in some embodiments, the reset action includes: Step S410, controlling the flip tank 100 to rotate to a first angle; Step S420, controlling the flip tank 100 to rotate to a second angle and detecting whether it is fully rotated; In step S430, when it is detected that the flip water tank 100 fails to rotate to the desired position, it is determined that a flip abnormality occurs in the current resetting action.

[0036] In this embodiment, the reset action includes a series of actions. If it is determined in step S230 that the flip tank 100 has failed to rotate to its proper position, the flip tank 100 is controlled to rotate to a first angle so that the flip tank 100 returns to a position where the opening is located on the side of the evaporator 200. The flip tank 100 is then controlled to rotate to a second angle again. If the second angle rotation still fails to rotate the flip tank 100 to its proper position, it is considered that this reset action has caused a flip abnormality. At this time, a field can be used to record the number of reset actions performed, and the recorded number of times is compared with a preset number. If the recorded number of times is less than the preset number, the next reset action is initiated. Otherwise, the attempt in step S310 is terminated. During the process of performing the reset action multiple times and checking whether a flip abnormality has occurred, if one or more reset actions do not cause a flip abnormality, the reset action test process in step S310 can be exited, and it is considered that the ice jam has been resolved or that the fault is a false alarm.

[0037] In addition to the above-mentioned steps S410 to S430, in some embodiments, the reset action can also be understood as a control action of controlling the flip tank 100 to rotate to the second angle. Because the state in which the flip tank 100 is rotated to the second angle is the normal position of the flip tank 100, this position is used as the reset position in the early design of the ice maker, and the action of rotating to the reset position is the reset action. Therefore, the reset action of performing the preset number of times in the above-mentioned step S310 can be controlling the flip motor 110 to rotate the second angle a preset number of times.

[0038] It is understandable that although the first angle and the second angle do not mention the rotation direction, according to the above steps, in order to control the flip tank 100 to move back and forth between the two positions, the rotation direction of the first angle is opposite to that of the second angle.

[0039] Reference Figure 5 As shown, in some embodiments, controlling the flip tank 100 to rotate to a second angle and detecting whether it is fully rotated includes: Step S510: sending a rotation instruction to the flip motor 110 to instruct the flip motor 110 to output a rotation action corresponding to the second angle; Step S520, receiving angle feedback information returned by the flip motor 110 after executing the rotation instruction; Step S530 , judging whether the rotation is in place based on the magnitude relationship between the actual rotation angle and the second angle indicated by the angle feedback information.

[0040] The controller of the ice maker sends a rotation instruction including a rotation angle or rotation position to the flip motor 110. The flip motor 110 converts the rotation instruction into a corresponding output parameter to control the rotation of the flip water tank 100. The flip motor 110 feeds back the angle through the motor encoder. In the related art, the motor encoder converts mechanical motion into an electrical signal by measuring the position, speed and direction of the rotor, so that the current position of the motor can be fed back to the control system by measuring the rotation angle or linear displacement of the motor shaft. After the flip motor 110 of the ice maker executes the rotation instruction, it returns angle feedback information through the motor encoder. Then the controller determines the actual rotation angle of the flip water tank 100 based on the angle feedback information, compares the actual rotation angle with the second angle, and determines whether the flip water tank 100 has been rotated to the correct position. If the actual rotation angle is different from the second angle, it is determined that the flip water tank 100 rotates to the second angle and a flip abnormality occurs, or a flip abnormality occurs when the reset action is performed.

[0041] Reference Figure 6 As shown, in some embodiments, in order to reasonably control the degree of heating and ice melting, it is necessary to record the output cooling capacity during the ice making process, so as to reversely heat and melt the ice according to the output cooling capacity. Specifically, in response to the ice making instruction, the columnar ice making coil 210 is controlled to cool, and the ice making time and ice making power are recorded; after ice making is completed, the ice removal operation is turned on. At this time, the control of the columnar ice making coil 210 to heat and melt ice in the above step S230 includes: Step S610, determining the ice melting time and / or ice melting power according to the ice making time and ice making power; Step S620: Control the columnar ice-making coil 210 to generate heat according to the ice-melting time and / or ice-melting power.

[0042] The ice-making time and power recorded during the ice-making process can be used to determine the cooling output of the evaporator 200. If ice jams occur during the de-icing process, heating can be performed based on the cooling output of the evaporator 200. For example, in step S610, the ice-melting time and / or power for heating can be determined based on the ice-making time and power, and then the heating of the evaporator 200 can be controlled based on the ice-melting time and / or power. Specifically, the total cooling capacity can be calculated based on the ice-making time and power. Based on the total cooling capacity, a melt time (which can be a preset time or a user-set time) can be set. The melt power can then be calculated based on the total cooling capacity and the melt time. In this way, the operating state of the compressor 300 can be controlled based on the melt power. The total cooling capacity calculated based on the ice-making time and power can be obtained by multiplying the ice-making time and power, or by performing some numerical processing on the multiplication of the ice-making time and power before being used as the total cooling capacity (because the de-icing process actually has a certain amount of heat output). For another example, the ice-melting time can be determined solely based on the ice-making time. In this case, only the ice-making time can be recorded, and the ice-melting time can be calculated based on the ice-making time. In this case, the compressor 300 can be controlled to operate at a constant power, thereby eliminating the need to record the ice-melting power. The ice-melting time and / or ice-melting power can also be calculated using other methods, which are not described in detail here.

[0043] In some embodiments, the ice maker includes a prompt component, which includes at least one of a display screen, a buzzer, and a prompt light, and is used to issue an ice stuck prompt through at least one of text, sound, and lighting effects. A prompt component can be set on the shell of the ice maker, and the prompt component can have different forms. If the ice stuck prompt needs to be issued through text, the prompt component can include a display screen for displaying text information; if the ice stuck prompt needs to be issued through sound, the prompt component can include a buzzer for issuing a sound reminder; if the ice stuck prompt needs to be issued through lighting effects, the prompt component can include a prompt light for the user to issue a light reminder. In some specific embodiments, the shell of the ice maker is provided with a display and control component, which has a display screen and control buttons, and can display a text ice stuck prompt through the display screen of the display and control component.

[0044] The ice maker 210 is controlled to heat the ice making coil 210 so that the ice cubes on the column head fall off. Then, the ice maker 210 is turned over again to rotate to the second angle. When the ice cubes are rotated to the second angle, the ice cubes can be pushed out smoothly. If the ice maker 210 fails to rotate to the second angle after rotating, it is determined that ice is stuck. In addition to issuing an ice stuck prompt, the ice maker 210 can also be controlled to heat the ice making coil 210 to melt the ice and solve the ice stuck problem by itself. Therefore, the ice maker of the embodiment of the present application can determine the ice stuck situation by the rotation angle of the turning tank 100, and solve the ice stuck problem by melting the ice when ice stuck occurs, thereby avoiding the ice maker from being stuck and unable to execute subsequent commands, and also saving the user the trouble of handling ice stuck by themselves.

[0045] The ice-removal control method of the ice maker of the present application is described in detail below through a specific example.

[0046] The ice maker in this example makes ice by inserting a columnar refrigeration coil into a reversing water tank 100. After ice making is completed, the column head of the columnar refrigeration coil is wrapped with ice cubes. At this time, the reversing water tank 100 is controlled to rotate to a first angle, forming a temporary ice loading cavity below the columnar refrigeration coil. Then, the ice cubes are de-iced by heating so that they fall into the temporary ice loading cavity. After that, the reversing water tank 100 is rotated at a second angle to return to the position when ice making was performed. In the case that ice is not stuck, the ice cubes can be pushed out of the temporary ice loading cavity into the ice storage bin. The specific de-icing control method includes: Step S1, the controller of the ice maker receives an ice removal instruction; Step S2, controlling the flip tank 100 to rotate to a first angle; Step S3, controlling the on-off valve 600 to open so that the high-temperature and high-pressure refrigerant at the exhaust port of the compressor 300 directly passes to the evaporator 200, and keeping the on-off valve 600 open for a preset time; Step S4, controlling the flip tank 100 to rotate to a second angle for resetting; Step S5: If it is detected that the flip tank 100 is rotated to the second angle, it indicates that there is no ice stuck, and the process goes to step Sx; Step S6: If it is detected that the flip tank 100 fails to rotate to the correct position, it indicates that the ice maker may be stuck in ice, and the process goes to step S7; Step S7, repeating the reset action N times (N is greater than or equal to 1), wherein the reset action includes first rotating the first angle and then rotating the second angle. If it is detected that the flip tank 100 fails to rotate to the desired position after N reset actions, it is determined that ice is stuck in the ice maker, and the process goes to step S8; Step S9: The display and control component displays an ice stuck prompt, and the system switches to ice removal mode. The on-off valve 600 is controlled to open, so that the high-temperature and high-pressure refrigerant from the exhaust port of the compressor 300 is directly passed to the evaporator 200, continuously heating the ice to melt it.
