[0049] Currently, small ice makers sometimes encounter the problem of large ice blocks getting stuck in the ice-tumbling mechanism when operating at different ambient temperatures. Existing solutions include lowering the water level in the tank or the evaporator height to reduce the ice height, but this significantly reduces the ice production capacity, failing to meet the claimed standards. Although variable frequency compressors can adjust their speed according to different ambient temperatures (low speed at low temperatures and high speed at high temperatures), the temperature of the water added by the user is unpredictable, making it difficult to effectively control the size of the ice and prevent ice blockage. The method provided in this application does not rely on adjusting the compressor speed based on ambient temperature, but rather adapts to different situations by adjusting the compressor's cooling capacity and the water tank height to achieve both ice blockage prevention and sufficient ice production capacity.

[0050] Figure 1 This application illustrates a control method for an ice maker, designed to improve its efficiency and reliability. The method utilizes intelligent control to address potential ice jamming issues during operation. By automatically detecting and adjusting the ice maker's operating parameters, it ensures smooth ice detachment, thereby avoiding manual intervention, reducing machine malfunctions and downtime, and improving ice-making efficiency. The control method includes:

[0051] Step 101: Determine that the ice maker is in an ice-jammed state during operation, and determine the ice removal parameters based on the current state parameters and initial operating parameters of the ice maker. The initial operating parameters are the operating parameters of the ice maker when it is started.

[0052] Step 102: Control the ice maker to continue making ice according to the de-icing parameters.

[0053] In one possible implementation, in step 101, determining that the ice maker is in an ice-jammed state during operation includes: controlling the water box to flip during the ice removal process to remove ice; detecting whether the water box is reset by a reset switch and a sensor; and determining that the water box cannot be reset after flipping a set number of times consecutively, if the water box cannot be reset, then the ice maker is determined to be in an ice-jammed state.

[0054] The system automatically detects whether the water tank has been reset by using a reset switch and sensors, reducing the need for manual inspection and improving detection efficiency.

[0055] In one possible implementation, step 101, determining the de-icing parameters based on the current state parameters and initial operating parameters of the ice maker, includes:

[0056] Based on the target parameter range and the current state parameters, the target state parameters are determined; the current state parameters include the current water box height and ice block diameter; based on the target state parameters and the initial operating parameters, the de-icing parameters are determined; the initial operating parameters include the compressor initial speed, the evaporator initial height, and the evaporator diameter.

[0057] Based on the ice maker's current status and initial operating parameters, the system automatically calculates and adjusts the ice removal parameters, enabling the ice maker to remove ice more effectively. This automatic detection and adjustment mechanism helps prevent machine damage caused by ice jams, extending the machine's lifespan. It also reduces the number of times users need to manually intervene due to ice jams, improving user satisfaction.

[0058] Suppose an ice maker is operating and the water tank fails to reset successfully during the ice removal process, even after three consecutive flips. The ice maker's built-in sensors and reset switch will detect this and automatically determine that the ice maker is stuck in an ice jam state. The system will determine target state parameters based on the current water tank height and ice cube diameter (current state parameters), as well as the compressor's initial speed, evaporator's initial height, and evaporator diameter (initial operating parameters). Based on the target state parameters, the system will automatically adjust the ice removal parameters, such as increasing the compressor speed or adjusting the evaporator's operating state, to more effectively promote ice removal. According to the new ice removal parameters, the ice maker will continue making ice, the ice cubes will fall off smoothly, the ice jam problem will be avoided, and the ice maker will resume normal operation. In this way, the ice maker can automatically resolve the ice jam problem without human intervention, improving the continuity and reliability of ice making.

[0059] In one possible implementation, in step 101, determining the target state parameter based on the target parameter range and the current state parameter includes: adjusting the water box height to a first target water box height, wherein the current water box height exceeds a set height threshold, and the first target water box height is within the target parameter range.

[0060] By adjusting the current water tank height to the first target water tank height, the water tank is ensured to be within the target parameter range, thus providing suitable conditions for de-icing.

[0061] In one possible implementation, in step 101, determining the de-icing parameters based on the target state parameters and the initial operating parameters includes: obtaining the water box height difference based on the difference between the first target water box height and the current water box height; obtaining the evaporator height difference based on the correspondence between the water box height and the evaporator height change and the water box height difference; calculating the first target compressor speed based on the evaporator height difference, the compressor initial speed, the evaporator initial height, and the evaporator diameter; the de-icing parameters include the first target water box height and the first target compressor speed.

[0062] Based on the correlation between the water box height difference and the evaporator height change, the evaporator height difference is automatically calculated. Combined with the compressor's initial speed, the evaporator's initial height, and the evaporator diameter, the first target compressor speed is calculated, enabling automatic adjustment of the de-icing parameters. The ice-jamming problem is solved by adjusting the water box height, and the ice-making diameter is increased by adjusting the compressor speed to compensate for any reduction in ice volume due to the lowered height, ensuring that the total volume and quality of the ice are not affected.

[0063] Assuming the ice maker detects that the current water tank height exceeds a set height threshold during operation, the system compares the current water tank height with the target parameter range and determines that the water tank height needs to be adjusted to the first target water tank height, which is within the target parameter range. The system calculates the difference between the current water tank height and the first target water tank height, i.e., the water tank height difference. Based on the correspondence between water tank height and evaporator height changes, the system calculates the evaporator height difference. Combining the evaporator height difference, the initial compressor speed, the initial evaporator height, and the evaporator diameter, the system calculates the first target compressor speed. The system sets the de-icing parameters to the first target water tank height and the first target compressor speed, controlling the ice maker to continue making ice according to these parameters. By adjusting the water tank height, the ice jam problem is solved, and by adjusting the compressor speed, the ice diameter is increased to compensate for the possible reduction in ice volume due to the reduced height, ensuring that the total volume and quality of the ice are not affected.

[0064] In one possible implementation, in step 101, determining the target state parameter based on the target parameter range and the current state parameter includes: adjusting the compressor speed to a second target compressor speed, wherein the current ice block diameter exceeds a set diameter threshold, and the second target compressor speed is within the target parameter range.

[0065] Based on the change in ice block diameter, the compressor speed is automatically adjusted to the second target compressor speed to meet the current ice-making needs.

[0066] In one possible implementation, in step 101, determining the de-icing parameters based on the target state parameters and the initial operating parameters includes: calculating the target evaporator height difference based on the second target compressor speed, the initial compressor speed, the initial evaporator height, and the evaporator diameter; obtaining the target water box height difference based on the correspondence between the water box height and the evaporator height change and the target evaporator height difference; obtaining the second target water box height based on the difference between the target water box height difference and the current water box height; the de-icing parameters include the second target water box height and the second target compressor speed.

[0067] By combining the second target compressor speed, the initial compressor speed, the initial evaporator height, and the evaporator diameter, the target evaporator height difference is calculated, and then the target water box height difference is obtained, thus achieving precise control of the de-icing parameters.

[0068] Assuming the ice maker detects that the current ice cube diameter exceeds a set threshold during operation, the system adjusts the compressor speed to a second target compressor speed, which falls within the target parameter range to accommodate changes in ice cube diameter. The system calculates the target evaporator height difference based on the second target compressor speed, the initial compressor speed, the initial evaporator height, and the evaporator diameter. Combining this with the correlation between water box height and evaporator height changes, the system calculates the target water box height difference. Based on the difference between the target water box height difference and the current water box height, the system calculates the second target water box height. The system sets the de-icing parameters to the second target water box height and the second target compressor speed, controlling the ice maker to continue making ice according to these parameters. By adjusting the compressor speed and water box height, the ice maker can effectively perform de-icing, allowing ice cubes to fall smoothly, avoiding ice jamming, and resuming normal operation.

[0069] Figure 2 The diagram shows the structure of an ice maker according to an embodiment of this application. The main components include a variable frequency compressor, a bottom condenser, a fan, a dryer filter, a capillary tube, a bullet-shaped evaporator, a return gas pipe, a three-way reversing valve, and a tilting motor. Specific functions are as follows:

[0070] Variable frequency compressor: The core component of an ice maker, the variable frequency compressor is responsible for compressing the refrigerant to achieve the refrigeration cycle. Variable frequency technology allows the compressor to adjust its operating speed according to actual cooling needs, improving energy efficiency and cooling performance.

[0071] Bottom condenser: Cools the high-temperature, high-pressure refrigerant gas discharged from the compressor into a high-pressure liquid. In small ice makers, the bottom condenser is usually located at the bottom of the machine, which helps to improve space utilization.

[0072] Fans: Fans are used to force airflow and accelerate the heat exchange process. In ice makers, fans may be used to cool the condenser to improve condensation efficiency, or to cool other components to maintain the machine's normal operating temperature.

[0073] Dryer filter: Removes moisture and impurities from the refrigerant, prevents system blockage and corrosion, ensures the purity of the refrigerant, thereby improving refrigeration efficiency and protecting the system.

[0074] Capillary tube: A capillary tube is a long, thin tube used to control the flow and pressure of the refrigerant, thereby controlling the cooling capacity of the evaporator. It acts as a throttling element in the refrigeration system.

[0075] Bullet-shaped evaporator: The evaporator is a key component of the refrigeration system, responsible for absorbing heat to evaporate the refrigerant, thereby achieving a cooling effect. It can effectively contact water, accelerating ice formation.

[0076] Return pipe: The return pipe connects the evaporator and the compressor, and is used to return the evaporated low-pressure refrigerant gas to the compressor to complete the refrigeration cycle.

[0077] A three-way reversing valve is used to control the flow of refrigerant, switching between cooling and heating modes. In ice makers, it may be used to control the flow of refrigerant to different evaporators to achieve different ice-making effects.

[0078] Tilting motor: Used to control the tumbling action in the ice maker, such as flipping the formed ice cubes off the evaporator for collection and removal. The motor drives the ice container to rotate, and the height of the water container can be controlled by adjusting the rotation angle of the motor.

[0079] Sensors: Sensors are responsible for monitoring the reset status of the ice box in real time. These may include ice thickness detectors, water level detectors, and box switches, which work together to ensure the smooth operation of the ice-making process. For example, an ice thickness detector can detect whether the ice has reached the set thickness, while a water level detector monitors whether the water level in the tank is appropriate.

[0080] Reset Switch: The reset switch is used to trigger a reset action manually or automatically if the ice container fails to reset successfully. It is a safety mechanism that ensures that manual intervention can be used to restore the ice maker to normal operation after automatic reset fails.

[0081] The control flow of the ice maker provided in the embodiments of this application is described below:

[0082] Phase 1: Start the ice maker and record the initial operating parameters.

[0083] Start the ice maker; the inverter compressor will begin running at its initial speed (Z0). Record the initial height of the evaporator (h0) and the evaporator diameter (d).

[0084] Phase Two: Ice making, ice removal, and ice jam detection.

[0085] Step 1: After the ice-making process is completed, the motor drives the water box to flip over to facilitate the ice falling off; the mechanism for flipping the water box includes: a motor-driven flipping mechanism; and an upper and lower clearance structure to facilitate the flipping of the water box.

[0086] Step 2: When the water box flips to a specific position, the reset switch will be triggered, indicating that the water box has reached the reset position; when the water box resets, the sensor will detect the presence or position change of the water box and send a signal to the control system.

[0087] Step 3: Record the number of times the water tank flips and resets. If the reset switch and sensor do not detect a reset action after the water tank has flipped a set number of times consecutively, the control system will determine that ice is stuck.

[0088] Third stage: If the system freezes, prompt the user to manually reset it.

[0089] Step 1: Prompt the user to manually reset the ice pack;

[0090] Step 2: If the user manually resets the ice box and resolves the ice jam issue, then no further ice jam adjustment process is required;

[0091] Step 3: If the user chooses not to manually reset, the ice maker will automatically attempt to reset the ice. If the failure occurs more than the set number of times, the ice jam adjustment process will be activated.

[0092] Fourth stage: Adjust the height of the water box.

[0093] The current water tank height is controlled by a motor to change to the set target water tank height, thereby reducing the height required to make ice blocks.

[0094] When the water tank height is reduced, the ice thickness may increase, causing the ice maker to require more energy to maintain the same ice production volume. Therefore, the compressor needs to operate at higher power. Conversely, when the water tank height is increased, the ice thickness may decrease, allowing the compressor to operate at lower power. This can reduce the energy required for the ice maker to make ice, thus saving energy.

[0095] Fifth stage: Determine the height difference of the evaporator.

[0096] Calculate the difference between the current water tank height and the set target water tank height, which is the water tank height difference; based on the correspondence between the water tank height difference and the evaporator height difference, obtain the evaporator height difference.

[0097] Stage 6: Calculate the compressor speed based on the evaporator height difference.

[0098] Calculate the new compressor speed based on the evaporator height difference to ensure sufficient ice production. Specifically, follow the formula below:

[0099]

[0100] Where Z is the new compressor speed, Z0 is the initial compressor speed, d is the evaporator diameter, h0 is the initial evaporator height, and Δh is the evaporator height difference.

[0101] The new compressor speed Z is the initial speed Z0 multiplied by an adjustment factor based on the change in evaporator height. If Δh (the height the evaporator lowers) is 0, then Z equals Z0, meaning the compressor speed remains constant. If Δh increases (evaporator height decreases), the denominator h0 decreases, causing the overall fraction to increase. This means Z increases, i.e., the compressor speed increases to generate more cooling to compensate for the increased ice thickness. If Δh decreases (evaporator height increases), the denominator h0 increases, causing the overall fraction to decrease. This means Z decreases, i.e., the compressor speed decreases to reduce cooling because the ice thickness has decreased. The ice maker automatically adjusts the compressor speed based on changes in evaporator height to optimize the ice-making process and energy efficiency.

[0102] Stage 7: Adjust the speed of the inverter compressor to Z to ensure ice production capacity.

[0103] The ice maker continues to run, constantly monitoring for ice jams, until the predetermined stopping conditions are met.

[0104] To optimize energy efficiency, ice makers can dynamically adjust compressor power based on actual ice-making needs and environmental conditions. For example, in high-temperature environments, the water tank height may need to be lowered to increase ice thickness and improve ice-making efficiency; conversely, in low-temperature environments, the water tank height can be increased to reduce ice thickness and lower compressor power consumption. This intelligent adjustment mechanism helps improve the energy efficiency of ice makers, reduce energy consumption, and ensure stable ice-making under different conditions. By integrating the calculation of compressor speed adjustment factors, ice makers can more accurately adjust compressor speed automatically based on changes in evaporator height, optimizing the ice-making process and energy efficiency. This ensures that ice makers can flexibly adjust to different ice-making conditions, guaranteeing both ice-making efficiency and quality.

[0105] Ice jamming is a complex problem that can be caused by a variety of factors, including evaporator design, refrigerant type, and environmental conditions. Therefore, resolving ice jamming requires a comprehensive approach, with compressor speed control being a crucial element, but it may need to be combined with other design and control strategies. If the ice maker's compressor speed is not calculated based on the evaporator's water tank height, the following alternative methods can be considered to adjust the compressor speed to optimize the ice-making process and energy efficiency:

[0106] 1. Refrigerant flow rate: Monitor the refrigerant flow rate and adjust the compressor speed to match the cooling demand.

[0107] 2. Evaporator temperature: Monitor the evaporator temperature and dynamically adjust the compressor speed to save energy or increase cooling capacity.

[0108] 3. Ambient temperature: Adjust the compressor speed according to changes in ambient temperature to maintain ice-making efficiency.

[0109] 4. Ice thickness sensor: The ice thickness sensor is used to monitor the ice thickness and trigger the adjustment of the compressor speed.

[0110] 5. Refrigerant pressure: Monitor the pressure in the refrigeration system and adjust the compressor speed to adapt to pressure changes.

[0111] 6. Ice production capacity requirements: The compressor speed is automatically adjusted according to the user's ice production capacity requirements to achieve a balance between energy efficiency and ice production capacity.

[0112] 7. Intelligent Control System: The intelligent control system uses algorithms to analyze historical data and current operating status to predict and automatically adjust the compressor speed to adapt to different ice-making conditions.

[0113] These alternative methods allow ice makers to effectively control compressor speed without relying on the height of the evaporator water box, thereby optimizing the ice-making process and improving energy efficiency.

[0114] In summary, this application provides a control method for an ice maker. By determining that the ice maker is in an ice-jammed state during operation, de-icing parameters are determined based on the current state parameters and initial operating parameters of the ice maker. The initial operating parameters are the operating parameters at startup of the ice maker. The ice maker is then controlled to continue making ice according to these de-icing parameters. This improves the operating efficiency and reliability of the ice maker, reducing downtime and ice-making failure rates caused by ice jams. The method also involves real-time monitoring of the ice maker's operating status and automatic adjustment of operating parameters to achieve de-icing when an ice-jammed state is detected.
