Description

Technical Field

[0001] This invention relates to the field of ice-making technology, and in particular to an ice maker and its control method and apparatus. Background Technology

[0002] With the improvement of living standards, household ice makers have become an important piece of equipment in modern family kitchens to enhance convenience. Ice makers typically use a single-layer plastic or metal ice storage box, relying on physical insulation materials (such as polyurethane foam) for passive insulation, which cannot effectively block the transfer of heat from the environment. In addition, the ice cubes have low bulk density and rough surfaces that make them easy to stick together, resulting in a high rate of ice breakage when taking out the ice.

[0003] Current technology uses a continuous cooling mode to maintain the ice storage temperature, which leads to excessive power consumption and generates a large amount of condensation on the outside of the ice maker, resulting in a poor user experience. Therefore, how to provide an ice maker with intelligent control has become an urgent technical problem to be solved. Summary of the Invention

[0004] This invention provides an ice maker and its control method and apparatus, which can reduce the power consumption of the ice maker and improve the user experience.

[0005] In a first aspect, the present invention provides a control method for an ice maker, the ice maker including a compressor, an ice dispensing motor, an ice dispensing screw, and an ice storage tank, the ice dispensing motor being mechanically connected to the ice dispensing screw, the ice dispensing screw being located inside the ice dispensing tank, and the ice dispensing screw being used to convey ice blocks to the ice outlet; The control method for the ice maker includes: When the ice maker receives an ice-making command, it acquires the amount of ice stored in the ice storage tank and the working status of the compressor in real time. When the ice maker is in ice-keeping mode, the cumulative ice-collecting time is acquired in real time within a preset time period; the ice-keeping mode is a mode in which the ice storage capacity is greater than the preset full ice capacity and the compressor is in a non-ice-making state. The operating status of the compressor is controlled based on the cumulative ice extraction time and the ice storage volume.

[0006] Optionally, the operating state of the compressor is controlled based on the cumulative ice harvesting time and the ice storage capacity, including: Determine whether the cumulative ice-collecting time is greater than a preset time; If so, the operating state of the compressor is controlled according to the ice storage capacity.

[0007] Optionally, if the cumulative ice-making time is less than or equal to the preset time, the compressor is controlled to remain in a non-ice-making state.

[0008] Optionally, after the ice maker receives an ice-making command and acquires the amount of ice stored in the ice storage tank and the operating status of the compressor in real time, the method further includes: Determine whether the ice storage amount is less than or equal to the preset full ice amount; If so, the compressor is controlled to be in ice-making mode until the ice storage amount is greater than the preset full ice amount.

[0009] Optionally, the control methods for the ice maker also include: Obtain the ice-keeping duration of the ice maker in ice-keeping mode; Determine whether the ice-keeping duration is greater than the preset time period, and whether the ice storage duration when the ice storage amount is less than or equal to the preset full ice amount is greater than the set duration; If so, the compressor is controlled to be in the ice-making state.

[0010] Optionally, if the ice-keeping duration is longer than the preset time period, and the ice storage amount is less than or equal to the ice storage duration of the full ice preset amount is less than or equal to the set duration, then the compressor is controlled to be in the non-ice-making state.

[0011] Optionally, the control methods for the ice maker also include: Starting from the moment the ice maker enters the ice-keeping mode, a stirring operation is performed once at preset intervals; The stirring operation involves controlling the ice-discharging motor to first drive the ice-discharging screw to rotate forward for a first preset time, and then controlling the ice-discharging screw to rotate in reverse for a second preset time after a first interval.

[0012] Optionally, the first preset duration is t1, and the second preset duration is t2; | t1-t2| / t1≤1%.

[0013] Secondly, the present invention provides a control device for an ice maker, the ice maker including a compressor, an ice dispensing motor, an ice dispensing screw and an ice storage tank, the ice dispensing motor being mechanically connected to the ice dispensing screw, the ice dispensing screw being located inside the ice dispensing tank, and the ice dispensing screw being used to convey ice blocks to the ice outlet; The control device for the ice maker includes: The parameter acquisition module is used to acquire the amount of ice stored in the ice storage tank and the working status of the compressor in real time when the ice maker receives the ice making command; The duration acquisition module is used to acquire the cumulative ice extraction time in real time within a preset time period when the ice maker is in ice-keeping mode; the ice-keeping mode is a state in which the ice storage amount is greater than the preset full ice amount and the compressor is in a non-ice-making state. The status control module is used to control the working status of the compressor based on the cumulative ice extraction time and the ice storage amount.

[0014] Thirdly, the present invention provides an ice maker, comprising: a compressor, an ice-discharging motor, an ice-discharging screw, an ice storage tank, an ice storage quantity detection device, and a controller; The ice-discharging motor is mechanically connected to the ice-discharging screw, which is located inside the ice-discharging bucket and is used to transport ice blocks to the ice outlet. The controller is electrically connected to the compressor, the ice-discharging motor and the ice storage detection device, respectively, and the controller is used to execute the control method of the ice maker described in the first aspect.

[0015] The technical solution provided by this invention obtains the amount of ice stored in the ice storage tank and the working status of the compressor in real time when the ice maker receives the ice-making command. When the ice maker is in ice-keeping mode, it obtains the cumulative ice-taking time in real time within a preset time period. Based on the cumulative ice-taking time and the amount of ice stored, the working status of the compressor is controlled to avoid the compressor working in ice-making mode for a long time, thereby reducing the power consumption of the ice maker and improving the user experience. Attached Figure Description

[0016] Figure 1 A flowchart illustrating a control method for an ice maker provided in an embodiment of the present invention; Figure 2 A flowchart illustrating another control method for an ice maker provided in an embodiment of the present invention; Figure 3 This is a schematic diagram of the structure of a control device for an ice maker provided in an embodiment of the present invention. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0018] The ice maker provided by the present invention includes a compressor, an ice dispensing motor, an ice dispensing screw, and an ice storage tank. The ice dispensing motor is mechanically connected to the ice dispensing screw, which is located inside the ice dispensing tank and is used to transport ice blocks to the ice outlet.

[0019] When the compressor is in ice-making mode, it allows the low-temperature, low-pressure refrigerant gas to absorb a large amount of heat from the ice tray or ice mold, compressing the gas into a high-temperature, high-pressure gas, causing the water in the tray or mold to freeze into ice. When the compressor is not in ice-making mode, it stops running or operates at low power, unable to absorb heat from the ice tray or mold, and therefore cannot make ice.

[0020] The ice-discharging motor can drive the ice-discharging screw to rotate forward or backward. When the ice-discharging screw rotates forward, it moves the ice block toward the ice outlet, and when it rotates backward, it moves the ice block away from the ice outlet. Alternatively, it can rotate forward to move the ice block away from the ice outlet and rotate backward to move the ice block toward the ice outlet. There are no restrictions here, as long as the direction of rotation of the ice-discharging screw is different.

[0021] Figure 1 This is a flowchart illustrating a control method for an ice maker according to an embodiment of the present invention, applicable to scenarios where the compressor's operating state is adjusted when the ice maker is in ice-keeping mode. Figure 1 As shown, the control method of the ice maker includes: S101. When the ice maker receives an ice-making command, it acquires the amount of ice stored in the ice storage tank and the working status of the compressor in real time.

[0022] Here, ice storage capacity refers to the proportion of the current amount of ice stored in the ice storage tank (which can be the ice level height) to the maximum amount of ice the ice storage tank can hold (which can be the total internal height of the ice storage tank). The ice maker includes a control panel and other ports that can input ice-making commands. The ice storage tank includes a detection device for detecting the amount of ice stored. The detection device includes, but is not limited to, infrared photoelectric sensors, mechanical ice probes, and capacitive sensors, which can be set according to actual needs and are not specifically limited here.

[0023] Specifically, when the ice maker receives an ice-making command, it means the user needs to control the ice maker to make ice. At this time, the controller inside the ice maker will control the compressor to enter ice-making mode. During the ice-making process, the amount of ice stored in the ice storage tank can be obtained through a detection device located in the ice storage tank. The operating status of the compressor can be obtained by monitoring the on / off state of the compressor's power supply circuit. If the power supply circuit is in a conducting state, it means the compressor is in ice-making mode; if the power supply circuit is in a disconnected state, it means the compressor is not in ice-making mode. Other methods can also be used to obtain the compressor's operating status, which are not specifically limited here.

[0024] S102. When the ice maker is in ice-keeping mode, the cumulative ice-collecting time is obtained in real time within a preset time period.

[0025] The ice-keeping mode is characterized by an ice storage capacity exceeding the preset full ice level and the compressor being in non-ice-making mode. The preset full ice level can be a fixed or variable value, optionally ranging from 95% to 99%. In one exemplary embodiment, the preset full ice level is 96%, but other values ​​are also possible. The ice maker is equipped with a timer that tracks the duration of each ice extraction, and the cumulative ice extraction time is calculated by adding up the durations of each extraction.

[0026] Specifically, when the ice storage tank contains more ice than the preset full ice capacity, it indicates that the ice storage tank is full and is in a full ice state. The compressor being in non-ice-making mode means that the compressor has stopped making ice.

[0027] It should be noted that before the ice maker is in ice-keeping mode, the amount of ice stored in the ice storage tank is less than or equal to the preset full ice capacity. The compressor needs to work continuously to make ice. If the user needs to use the ice during the ice-making process, the user can control the compressor to be in non-ice-making mode through the control panel of the ice maker to remove the ice. After removing the ice, the user can then control the ice maker to start making ice, and the compressor will enter the ice-making mode to make ice.

[0028] S103. Control the operating status of the compressor based on the cumulative ice extraction time and ice storage volume.

[0029] The compressor's operating states include ice-making and non-ice-making states.

[0030] Specifically, if the cumulative ice-collecting time exceeds the preset time and the ice storage volume is less than or equal to the preset full ice volume, it indicates that the ice storage volume in the ice tank is low and may not meet the user's ice-collecting needs. In this case, the compressor needs to be switched to ice-making mode to increase the ice storage volume in the ice tank to meet the user's ice-collecting needs. If the cumulative ice-collecting time is less than the preset time, it means that the user has taken out relatively little ice from the ice tank within the cumulative ice-collecting time, and the ice tank still stores a large amount of ice, which can meet the user's ice-collecting needs. In this case, the compressor can be switched to non-ice-making mode to reduce the power consumption of the ice maker while ensuring that the ice storage volume in the ice tank meets the user's needs and improves the user experience.

[0031] The technical solution of this invention obtains the amount of ice stored in the ice storage tank and the working status of the compressor in real time when the ice maker receives the ice-making command. When the ice maker is in ice-keeping mode, it obtains the cumulative ice-taking time in real time within a preset time period. Based on the cumulative ice-taking time and the amount of ice stored, the working status of the compressor is controlled to avoid the compressor working in ice-making mode for a long time, reduce the power consumption of the ice maker, and improve the user experience.

[0032] Based on the above embodiments, this embodiment of the invention describes how to control the working state of the compressor according to the cumulative ice extraction time and the ice storage amount. Figure 2 A flowchart of another control method for an ice maker provided in an embodiment of the present invention is shown below. Figure 2 As shown, the control method of the ice maker includes: S201. When the ice maker receives an ice-making command, it acquires the amount of ice stored in the ice storage tank and the working status of the compressor in real time.

[0033] S202. When the ice maker is in ice-keeping mode, the cumulative ice-collecting time is obtained in real time within a preset time period.

[0034] The ice-keeping mode is a state where the ice storage capacity is greater than the preset full ice capacity and the compressor is in a non-ice-making state.

[0035] S203. Determine whether the cumulative ice-collecting time is greater than the preset time; if yes, execute S204; if no, execute S205.

[0036] The preset duration can be a fixed value or a non-fixed value, and can be set according to actual needs. Optionally, the preset duration ranges from 10s to 20s. In an exemplary embodiment, the preset duration is 10s, but it can also be other values, which are not specifically limited here.

[0037] S204. Control the compressor's operating status according to the ice storage capacity.

[0038] Specifically, if the cumulative ice removal time exceeds the preset time, it indicates that the user has removed a large amount of ice from the ice storage tank during the current ice-keeping mode, potentially resulting in a low ice level in the tank. In this case, the compressor will be controlled to operate in ice-making mode based on the current ice level. If the current ice level is less than or equal to the preset full ice level, the compressor will operate in ice-making mode; if the current ice level is greater than the preset full ice level, the compressor will operate in non-ice-making mode.

[0039] S205, Control the compressor to remain in non-ice-making state.

[0040] Specifically, if the cumulative ice-taking time is less than or equal to the preset time, it means that during the current ice-keeping mode, the amount of ice taken out by the user from the ice storage tank is small, and the remaining ice storage in the ice storage tank can meet the user's ice-taking needs. At this time, the compressor is kept in non-ice-making state, which can still enable the ice maker to meet the user's ice-taking needs, improve the user experience, and reduce the power consumption of the ice maker.

[0041] It should be noted that when the cumulative ice-collecting time is less than or equal to the preset time, the amount of ice stored in the ice storage tank may be less than or equal to the preset full ice capacity. However, because the cumulative ice-collecting time is short, the amount of ice taken out by the user from the ice storage tank is small, resulting in a large amount of ice remaining in the ice storage tank, possibly greater than 75%, which can still meet the user's ice-collecting needs for a certain period of time. Therefore, in this case, it is not necessary to obtain the amount of ice stored in the ice storage tank, and the compressor can be directly controlled to be in non-ice-making mode, which can significantly reduce the power consumption of the ice maker.

[0042] In another optional embodiment, the control method for the ice maker further includes obtaining the ice-keeping duration when the ice maker is in the ice-keeping mode; determining whether the ice-keeping duration is greater than a preset time period, and whether the ice-keeping duration when the ice storage amount is less than or equal to the preset full ice amount is greater than the set duration; if so, controlling the compressor to be in the ice-making state.

[0043] The ice-keeping duration refers to the duration the ice maker maintains its ice-keeping function from the start of the ice-keeping mode. Both the preset time period and the set duration can be fixed or variable values, and can be set according to actual needs. Optionally, the preset time period can range from 2 hours to 4 hours, and the set duration can range from 1 hour to 1.5 hours. In an exemplary embodiment, the preset time period is 2 hours and the set duration is 1 hour; other values ​​are also possible and are not specifically limited here.

[0044] Specifically, during the ice-keeping period, the compressor is in non-ice-making mode. The ice stored in the ice storage tank relies on the physical insulation layer of the tank for insulation. However, the physical insulation layer has limited effectiveness in blocking ambient heat and cannot guarantee that the ice will not melt for an extended period. Therefore, if the ice-keeping period exceeds the preset time period, and the ice storage time is less than or equal to the preset full ice capacity, it indicates that at least some of the ice in the ice storage tank has melted. If the compressor is not operated at this time, the melted water will further melt the remaining ice, further reducing the ice storage capacity in the tank. Therefore, it is necessary to control the compressor to start ice-making mode to increase the ice storage capacity in the tank until it exceeds the preset full ice capacity to meet the user's ice-taking needs.

[0045] Optionally, if the ice-keeping time is longer than the preset time period, and the ice storage time is less than or equal to the preset full ice quantity and less than or equal to the set time, the compressor is controlled to be in non-ice-making state.

[0046] Specifically, if the ice-keeping time is longer than the preset time period, and the ice storage time is less than or equal to the preset full ice quantity, it means that the amount of ice that has melted in the ice storage tank is small and will not cause a sudden drop in the ice storage tank in a short period of time. Therefore, the compressor is controlled to be in non-ice-making state at this time, which can still ensure that the ice storage in the ice storage tank meets the user's ice-taking needs and improve the user experience.

[0047] In an optional embodiment, after the ice maker receives an ice-making command and obtains the amount of ice stored in the ice storage tank and the working status of the compressor in real time, the method further includes: determining whether the amount of ice stored is less than or equal to the preset amount of full ice; if so, controlling the compressor to be in ice-making state until the amount of ice stored is greater than the preset amount of full ice.

[0048] Specifically, upon receiving an ice-making command, if the ice storage amount is less than or equal to the preset full ice amount, it indicates that the ice storage tank is not full. In this case, the compressor is controlled to enter ice-making mode to increase the ice storage amount in the ice storage tank, so that the ice storage amount in the ice storage tank is greater than the preset full ice amount, thereby meeting the user's ice-taking needs.

[0049] In an optional embodiment, the control method for the ice maker further includes: starting from the moment the homemade ice maker enters the ice-keeping mode, performing a stirring operation once at preset intervals.

[0050] The stirring operation involves controlling the ice-discharging motor to first drive the ice-discharging screw to rotate forward for a first preset time, and then controlling the ice-discharging screw to rotate in reverse for a second preset time after a first interval.

[0051] The preset time, the first interval duration, the first preset duration, and the second preset duration can be fixed or non-fixed values, and can be set according to implementation needs. Optionally, the preset time ranges from 10 min to 30 min, the first interval duration ranges from 0.5 s to 1 s, and the first and second preset durations range from 2 s to 5 s. In an exemplary embodiment, the preset time is 10 min, the first interval duration is 0.5 s, and both the first and second preset durations are 2 s. Other values ​​are also possible, and no specific limitation is made here.

[0052] Specifically, after a preset time interval, the ice cubes in the ice storage tank may stick together, affecting user experience. Therefore, after a preset time interval, the ice dispensing screw is controlled to rotate forward for a first preset time, and then reverse for a second preset time after the first interval. This effectively agitates the ice cubes in the storage tank and prevents them from being conveyed in one direction when not dispensing ice, thus avoiding ice cubes falling into the dispensing port. In this way, from the start of the ice-keeping mode, the homemade ice maker performs an agitation operation at preset time intervals, effectively agitating the ice cubes in the storage tank, reducing ice cube sticking, and improving the smoothness and stability of ice dispensing. Furthermore, using the forward and reverse rotation of the ice dispensing screw for agitation effectively avoids the need for additional ice-stirring structures, simplifying the internal structure of the ice maker.

[0053] Optionally, the first preset duration is t1, and the second preset duration is t2; |t1-t2| / t1≤1%.

[0054] Specifically, by setting the absolute value of the difference between the first preset duration t1 and the second preset duration t2 to be less than or equal to 1%, the first preset duration t1 and the second preset duration t2 are equal or have a small difference, so that the ice blocks can return to their original positions after each reversal, and the ice blocks are prevented from accumulating in the direction of the ice outlet or away from the ice outlet.

[0055] Based on the same inventive concept, the present invention also provides a control device for an ice maker. Figure 3 This is a schematic diagram of the structure of a control device for an ice maker provided in an embodiment of the present invention, as shown below.

The duration acquisition module 20 is used to acquire the cumulative ice extraction time in real time within a preset time period when the ice maker is in ice-keeping mode; the ice-keeping mode is the state where the ice storage is greater than the preset full ice amount and the compressor is in non-ice-making state. The status control module 30 is used to control the working status of the compressor based on the cumulative ice extraction time and ice storage amount.
