Description

[0002] With the improvement of living standards, people's demand for multifunctional refrigerators has gradually increased. At present, many refrigerators on the market are equipped with automatic ice makers to meet the needs of users to drink cold drinks at any time during the hot summer.

[0003] The automatic ice maker in a refrigerator requires water to be drawn in through an inlet pipe to make ice. Because the water in the inlet pipe is exposed to low temperatures, it easily freezes, causing ice blockage. This inlet pipe blockage not only affects ice-making efficiency but can also cause refrigeration system failure. Existing technologies use external electric heating wires to heat the inlet pipe to prevent ice blockage. However, due to the limited heating effect of the electric heating wires and the hysteresis in their control, these methods are less effective in preventing blockage. Summary of the Invention

Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0049] The present application provides a control method for an ice-making device, which may be an independent ice-making machine or a refrigeration module in a refrigeration device such as a refrigerator. Figure 1 , Figure 1 This is a flow chart of a control method provided in an embodiment of the present application. The ice-making device includes a water inlet pipe and a heating component. The heating component is disposed on the water inlet pipe and is suitable for heating the water inlet pipe. The control method includes the following steps S101-S104:

[0050] Step S101: obtaining the current ambient temperature;

[0051] The ambient temperature is acquired by an environmental sensor, such as a temperature and humidity sensor or an independent temperature sensor. The environmental sensor collects data periodically at a preset sampling frequency (e.g., once per minute), or is triggered by a control module to collect data in real time.

[0052] Step S102: If the ambient temperature is lower than the first preset temperature, obtaining the first temperature of the current water inlet pipe, and obtaining the first duration information of the current ice-making cycle and the second duration information of the previous ice-making cycle;

[0053] It should be noted that each ice-making cycle of an ice-making device includes the following stages: water filling, freezing, de-icing, ice storage, and reset. During the water filling stage, the ice-making device uses a water pump to pump water from the water tank into the ice tray through the water inlet pipe. During the freezing stage, the ice-making device's compressor turns on, radiating cooling energy to the ice tray through the evaporator, causing the water in the ice tray to gradually freeze into ice cubes. During the de-icing stage, the ice-making device removes the ice cubes from the ice tray through heating, mechanical de-icing, or other methods. During the ice storage stage, the ice-making device transfers the removed ice cubes into the ice storage bin. Finally, during the reset stage, the various modules of the refrigeration device automatically reset and prepare for the next ice-making cycle.

[0054] The current ice-making cycle indicates the ice-making cycle that the ice-making device is currently in. If the ice-making device is not currently in an ice-making cycle, the current ice-making cycle indicates the ice-making cycle that the ice-making device is about to enter. The last ice-making cycle indicates the ice-making cycle before the current ice-making cycle if the ice-making device is currently in an ice-making cycle. If the ice-making device is not currently in an ice-making cycle, the last ice-making cycle indicates the most recently completed ice-making cycle of the ice-making device.

[0055] It should be noted that the first duration information may include the total duration of the current ice-making cycle, and may also include the duration of each ice-making stage of the ice-making device in the current ice-making cycle, such as the duration of water filling the ice-making device in the current ice-making cycle. The second duration information may include the total duration of the previous ice-making cycle, and may also include the duration of each ice-making stage of the ice-making device in the previous ice-making cycle, such as the duration of water filling the ice-making device in the previous ice-making cycle.

[0056] If the current ambient temperature is detected to be lower than a first preset temperature, it indicates that the current ambient temperature is too low, making the water inlet pipe susceptible to ice blockage. Therefore, it is necessary to monitor the temperature of the water inlet pipe and the duration of the current ice-making cycle to promptly determine whether the water inlet pipe is ice-blocked. For example, the first preset temperature may be 12°C.

[0057] Step S103: determining whether the current water inlet pipe is blocked by ice based on the first temperature, the first duration information, and the second duration information;

[0058] It is understandable that when the water inlet pipe is blocked by ice, the heat exchange of the water inlet pipe will be unbalanced, and the water inlet pipe will show a temperature lower than normal. Therefore, by obtaining the first temperature, the current ice blockage situation of the water inlet pipe can be determined. On the other hand, when the water inlet pipe is blocked by ice, the diameter of the water inlet pipe at the blocked point will be reduced, which will in turn reduce the water flow rate of the water inlet pipe when it is entering the water, making it take more time for the water inlet pipe to inject the target amount of water into the ice tray; at the same time, the ice blockage of the water inlet pipe may also affect the heat exchange efficiency of the refrigeration system, thereby affecting the freezing time of the water. For some types of ice-making devices, it may also affect the defrosting time and reset time. Therefore, the first time information and the second time information can also reflect the freezing situation of the water inlet pipe, which can be used to determine whether the water inlet pipe is blocked by ice.

[0059] Step S104: If it is determined that the water inlet pipe is currently blocked by ice, the heating component is controlled to turn on.

[0060] The heating component is suitable for heating the water inlet pipe to eliminate ice in the water inlet pipe and ensure that the ice making device can perform the water inlet operation normally.

[0061] The control method of the ice-making device provided in the embodiment of the present application monitors the internal temperature of the water inlet pipe and the duration information of the ice-making cycle in a low-temperature environment, so as to timely understand the ice blockage situation of the water inlet pipe, and then eliminate the ice blockage in time when it occurs, thereby ensuring the normal and stable water inlet operation of the ice-making device.

[0062] Regarding how to determine whether the water inlet pipe is blocked by ice, the present application provides the following implementation method. Determining whether the water inlet pipe is blocked by ice based on the first temperature, the first duration information, and the second duration information includes:

[0063] Extracting the first total duration of the current ice-making cycle from the first duration information, and extracting the second total duration of the previous ice-making cycle from the second duration information;

[0064] It is determined whether the current water inlet pipe is blocked by ice according to the relationship between the first temperature, the first total time and the second total time.

[0065] It is understandable that if the water inlet pipe is blocked by ice, it will cause slow water inflow to the ice-making device and abnormal cooling of the refrigeration system, resulting in an abnormal total duration of the current ice-making cycle. Therefore, by comparing the first total duration with the second total duration, it is possible to determine whether there is any abnormality in the current ice-making cycle compared to the previous ice-making cycle, and thus serve as a basis for determining whether the current water inlet pipe is blocked by ice.

[0066] Illustratively, judging whether the current water inlet pipe is blocked by ice based on the relationship between the first temperature, the first total time, and the second total time includes:

[0067] Obtaining a second preset temperature and a first preset coefficient;

[0068] If the first temperature is lower than the second preset temperature, and / or the first total time is greater than the product of the second total time and the first preset coefficient, it is determined that ice blockage exists in the current water inlet pipe;

[0069] The first preset coefficient is greater than 1.

[0070] It can be understood that if the first preset coefficient is greater than 1, the product of the second total time and the first preset coefficient is greater than the second total time. When the first total time is greater than the product of the second total time and the first preset coefficient, it means that the current first total time is large, and the water injection time may be prolonged due to ice blockage. The first preset coefficient is, for example, 1.2. Preferably, when the first temperature is lower than the second preset temperature, and the first total time is greater than the product of the second total time and the first preset coefficient, it is determined that there is ice blockage in the current water inlet pipe. In this way, the accuracy of the ice blockage state judgment can be improved. The second preset temperature is, for example, 3°C. Taking into account the instability of the water pump pressure of the ice-making device, the first preset coefficient can be appropriately set to be slightly larger according to the actual situation to reduce the probability of misjudgment of the ice blockage state.

[0071] Regarding how to determine whether the water inlet pipe is blocked by ice, the present application also provides a parallel implementation method, which includes: determining whether the water inlet pipe is blocked by ice based on the first temperature, the first duration information, and the second duration information.

[0072] Extracting the first water inflow duration of the current ice-making cycle from the first duration information, and extracting the second water inflow duration of the previous ice-making cycle from the second duration information;

[0073] It is determined whether the water inlet pipe is currently blocked by ice according to the relationship between the first temperature, the first water inlet time and the second water inlet time.

[0074] It's understandable that the first water inlet duration reflects the water inlet efficiency of the water inlet pipe during the current ice-making cycle. If the first water inlet duration is longer than the second water inlet duration, it indicates a decrease in the water flow rate per unit time in the current water inlet pipe, possibly due to ice blockage. Therefore, by comparing the first and second water inlet durations, it's possible to determine whether the water inlet efficiency has decreased during the current ice-making cycle compared to the previous one, and thus, whether the current water inlet pipe is blocked by ice.

[0075] Exemplarily, judging whether the water inlet pipe is currently blocked by ice based on the relationship between the first temperature, the first water inlet time, and the second water inlet time includes:

[0076] Obtaining a second preset temperature and a first preset coefficient;

[0077] If the first temperature is lower than the second preset temperature, and / or the first water inlet time exceeds the product of the second water inlet time and the first preset coefficient, it is determined that ice blockage exists in the current water inlet pipe.

[0078] Preferably, if the first temperature is lower than the second preset temperature and the first water inlet duration is greater than the product of the second water inlet duration and the first preset coefficient, then it is determined that the water inlet pipe is currently blocked by ice. This improves the accuracy of ice blockage determination. The first preset coefficient is, for example, 1.2. The second preset temperature is, for example, 3°C. Considering the instability of the water pump pressure in the ice-making device, the first preset coefficient can be appropriately set slightly higher based on actual conditions to reduce the probability of misjudging the ice blockage.

[0079] In some embodiments, after controlling the heating component to turn on, the method further includes:

[0080] Obtain the second temperature of the current water inlet pipe and the water flow rate during water inlet;

[0081] If the second temperature is greater than the third preset temperature, or the water flow rate reaches the target flow rate, the heating component is controlled to be turned off.

[0082] As will be appreciated, after the heating assembly is activated, the ice in the water inlet pipe gradually disappears, and the water inlet pipe temperature gradually rises. When the second water inlet pipe temperature rises above a third preset temperature, it indicates that the ice blockage is about to disappear or has completely disappeared. Alternatively, when the water flow rate reaches the target flow rate, it indicates that the diameter of the water flow channel in the water inlet pipe has returned to a normal range, indicating that the ice blockage is about to disappear or has completely disappeared. The third preset temperature is, for example, 5°C.

[0083] After the heating component is turned off, there is usually residual heat left, and the residual heat of the heating component can continue to melt the ice in the water inlet pipe. In order to achieve the effect of energy saving, the third preset temperature can be set slightly lower to achieve the effect of turning off the heating component in advance. In addition, the target flow rate can also be set to the product of the reference flow rate when the water inlet pipe is normally flowing with water and the second preset coefficient, where the second preset coefficient is less than 1. The reference flow rate when the water inlet pipe is normally flowing with water represents the water flow rate when there is no ice blockage in the water inlet pipe. In this way, when it is detected that the water flow rate reaches the target flow rate, it means that the ice blockage is about to disappear. At this time, the heating component is turned off in advance, and the residual heat is used to melt the remaining ice, which can achieve the effect of energy saving. The second preset coefficient is, for example, 0.95.

[0084] In some embodiments, after obtaining the current ambient temperature, the method for controlling the ice-making device further includes:

[0085] When the ambient temperature is higher than or equal to the first preset temperature, in response to an ice-making instruction of the ice-making device, obtaining a third temperature of the water inlet pipe within a preset time period;

[0086] If the third temperature is lower than the fourth preset temperature, the heating component is controlled to turn on.

[0087] It should be noted that, in response to an ice-making instruction from the ice-making device, the ice-making device controls the opening of the water inlet valve to allow the water inlet pipe to fill the ice tray. Exemplarily, the preset time period includes the period from a first preset moment before the water inlet solenoid valve opens to a second preset moment when the water inlet solenoid valve opens, for example, 30 seconds before and 30 seconds after the water inlet solenoid valve opens. Obtaining a third temperature of the water inlet pipe during the preset time period means obtaining the water inlet pipe temperature during the preset time period before and after the water inlet solenoid valve opens to determine whether there is ice blockage in the water inlet pipe. If the third temperature is lower than a fourth preset temperature, the water inlet pipe temperature was too low during the preset time period before and after the water inlet solenoid valve opened, potentially causing ice blockage and impacting normal water supply to the ice-making device. Controlling the heating assembly to activate when the third temperature is lower than the fourth preset temperature can eliminate any ice blockage that may have occurred before and after the water inlet solenoid valve opened, ensuring normal water supply to the ice-making device. The fourth preset temperature is, for example, greater than or equal to the second preset temperature.

[0088] Optionally, after controlling the heating component to turn on, the control method also includes obtaining the fourth temperature of the current water inlet pipe and the water flow rate during water inlet; if the fourth temperature is greater than the fifth preset temperature, or the water flow rate reaches the target flow rate, the heating component is controlled to turn off.

[0089] The control method of the ice-making device provided in the embodiment of the present application monitors the internal temperature of the water inlet pipe and the duration information of the ice-making cycle in a low-temperature environment, so as to timely understand the ice blockage situation of the water inlet pipe, and then eliminate the ice blockage in time when it occurs, thereby ensuring the normal and stable water inlet operation of the ice-making device.

[0090] The present application also provides a control device for an ice making device. For example, see Figure 2 , Figure 2 This is a schematic diagram of the structure of the control device provided in an embodiment of the present application. The ice-making device includes a water inlet pipe and a heating assembly. The heating assembly is disposed on the water inlet pipe and is suitable for heating the water inlet pipe. The control device 200 includes an acquisition module 210, a determination module 220, and a control module 230.

[0091] Among them, the acquisition module 210 is used to obtain the current ambient temperature. If the ambient temperature is lower than the first preset temperature, the first temperature of the current water inlet pipe is obtained, and the first duration information of the current ice-making cycle and the second duration information of the last ice-making cycle are obtained; the judgment module 220 is used to judge whether the current water inlet pipe is blocked by ice based on the first temperature, the first duration information and the second duration information; the control module 230 is used to control the heating component to turn on after determining that the current water inlet pipe is blocked by ice.

[0092] The control device of the ice-making device provided in the embodiment of the present application monitors the internal temperature of the water inlet pipe and the duration information of the ice-making cycle in a low-temperature environment, so as to timely understand the ice blockage situation of the water inlet pipe, and then eliminate the ice blockage in time when it occurs, thereby ensuring the normal and stable water inlet operation of the ice-making device.

[0093] The present application also provides a refrigerator, for example, see Figure 3-Figure 5 , Figure 3 This is a schematic diagram of the structure of the refrigerator provided in the embodiment of the present application. Figure 4 This is another structural schematic diagram of a refrigerator provided in an embodiment of the present application. Figure 5 This is another structural diagram of a refrigerator provided in an embodiment of the present application.

Refrigerator 300 includes an ice-making device 310 and a controller 320 .

[0094] The ice-making device 310 includes a water inlet pipe 311 and a heating component 312. The heating component 312 is arranged on the water inlet pipe 311 and is suitable for heating the water inlet pipe 311. The controller 320 is connected to the heating component 312 and is used to: obtain the current ambient temperature.

[0095] To improve the heating efficiency of the water inlet pipe 311 by the heating assembly 312, the heating unit of the heating assembly 312 is preferably embedded in the body of the water inlet pipe 311. The heating unit is, for example, a heating wire with a diameter of 0.2 mm and a single helical structure. Preferably, the temperature sensor of the ice making device 310 for detecting the temperature of the water inlet pipe 311 is also embedded in the water inlet pipe 311 to improve the accuracy of temperature detection.

[0096] In the refrigerator 300 provided in the embodiment of the present application, the controller 320 monitors the internal temperature of the water inlet pipe 311 of the ice-making device 310 and the duration information of the ice-making cycle in a low-temperature environment, so as to timely understand the ice blockage situation of the water inlet pipe 311, and then eliminate the ice blockage in time when it occurs, thereby ensuring the normal and stable water inlet operation of the ice-making device 310.
