[0003] This application provides an ice-making method for an ice-making device, which reduces the power consumption of the heating device at the liquid injection pipe.

[0004] Specifically, this application is implemented through the following technical solutions:

[0005] One aspect of this application provides an ice-making method for an ice-making device. A heating device is provided on the liquid injection pipe of the ice-making device. The method includes:

[0006] In the working process of the ice-making device, controlling the heating device to perform a heating operation.

[0007] The ice-making device includes an initial turn-on rate and a reference temperature value. When the internal temperature of the ice-making device is at the reference temperature value, the turn-on rate is the initial turn-on rate; when the internal temperature of the ice-making device decreases by a first temperature based on the reference temperature value, the turn-on rate increases by a first set value based on the initial turn-on rate.

Control the liquid injection pipe to always maintain a specific temperature range, avoiding that when the temperature is too low, the startup rate is not enough to freeze the liquid injection pipe; and the startup rate is too high, which does not match the current temperature, resulting in an increase in power consumption. Therefore, the present application can reduce the power consumption of the heating device and ensure normal water injection of the liquid injection pipe. Description of the Drawings

For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0032] The present application provides an ice-making method for an ice-making device. A heating device is provided on the liquid injection pipe of the ice-making device. For example, it can be a heating wire wound around the end of the liquid injection pipe facing the water inlet inside the ice-making device. The heating device in the following text refers to the heating device provided at the liquid injection pipe. After the ice-making device finishes water injection, it enters the ice-making process. During the ice-making work process, controlling the heating device to perform a heating operation is to ensure that the liquid injection pipe is not blocked by freezing, thereby affecting water injection. The heating operation includes at least one heating process. The heating process includes: continuously turning on for a first duration within a fixed cycle duration, and the first duration is less than the fixed cycle duration. That is, the percentage of the ratio of the first duration to the fixed cycle duration is the turn-on rate. The turn-on rate can be less than 1. For example, the cycle duration is 60 seconds, and the first duration is less than 60 seconds. Here, any liquid can be injected into the liquid injection pipe, and in this text, the injected liquid is water for illustration. Among them, the cold air in the ice-making process can be the ice-making device's own refrigeration, or when the ice-making device is installed in a refrigerator, the cold air required for ice-making can be provided by the refrigerator's compressor. Specifically, along the height direction of the refrigerator, the liquid outlet end of the liquid injection pipe is arranged above the ice tray. The ice tray can be directly or indirectly arranged in the freezer of the refrigerator. The cold air provided by the compressor is blown into the freezer of the refrigerator, which can directly or indirectly cool the ice tray. At this time, when there is liquid at the liquid outlet end of the liquid injection pipe located above the ice tray, it is very easy to be blocked by freezing.

[0033] In order to ensure that the liquid injection pipe is not blocked by freezing, it is only necessary to ensure that the water injection port of the liquid injection pipe is within a specific temperature range, such as 5°-10°. It is not necessary to keep the heating device on all the time to heat the liquid injection pipe. The present application sets the heating device to heat for the first duration within one heating process and continuously cycles the heating process, which not only meets the temperature of the liquid injection pipe and prevents the liquid injection pipe from being frozen.

[0034] Furthermore, the ice-making device includes an initial turn-on rate and a reference temperature value. When the internal temperature of the ice-making device is at the reference temperature value, the turn-on rate is the initial turn-on rate. When the internal temperature of the ice-making device decreases by the first temperature based on the reference temperature value, the turn-on rate increases by the first set value based on the initial turn-on rate. The temperature can be measured by a temperature sensor provided inside the ice-making device. The lower the temperature inside the ice-making device, the easier it is for the liquid injection pipe to be frozen. Therefore, when the internal temperature change of the ice-making device is detected, the turn-on rate can be dynamically adjusted. Control the liquid injection pipe to always remain within a specific temperature range, avoiding that when the temperature is too low, the turn-on rate is not enough to freeze the liquid injection pipe; and when the turn-on rate is too high, it does not match the current temperature, resulting in an increase in power consumption. Therefore, the present application can reduce the power consumption of the heating device and ensure normal water injection of the liquid injection pipe.

[0035] Among them, the reference temperature value can be -18°C, the set startup rate can be N%, and the relationship between the first temperature and the first set value is set differently according to different models of ice-making devices, which is related to factors such as the refrigeration wind speed, compressor frequency, fan speed, air outlet position, and water outlet position of the ice-making device. Different ice-making devices can be measured through experiments. In all the following embodiments, the heating process of the heating device can be to use the scheme of dynamically adjusting the startup rate in this embodiment. The heating process of this embodiment can be used in any usage state of the heating device. For example, during the preheating process, the injection pipe opens the heating device to heat the injection pipe, or during the water injection process of the injection pipe, the heating device is opened to heat the injection pipe, etc. Here, the proportion of the usage time of the heating device in the entire heating process, as well as the startup timing of the heating device, etc. are not limited.

[0036] In one embodiment, the first set value is proportional to the diameter of the injection pipe of the ice-making device. When the diameter of the injection pipe is large, the thermal conductivity is low, so the time required to heat the injection pipe is relatively long. Therefore, for a larger-diameter injection pipe, a larger first set value can be set to ensure the temperature of the injection pipe with a larger diameter.

[0037] In one embodiment, please refer to Figure 1 and Figure 2 , the working process of the ice-making device includes an ice-making working process S3. The ice-making working process S3 includes an S31 injection process and an S32 ice-making process. Controlling the heating device to perform a heating operation includes: controlling the heating device to perform a heating operation in the S31 injection process. In the S31 injection process, there is flowing water in the injection pipe, and the heating device is required to heat. After the S31 injection process ends, it enters the S32 ice-making process. The injection pipe does not need to be filled with water, and at this time, the injection pipe can also be allowed to freeze, which will not affect the water inlet. Therefore, the heating device can be turned off. Wait until the next water injection to turn on the heating device to heat the injection pipe. In this embodiment, turning off the heating device after the injection process ends can reduce the startup time of the heating device and further reduce the power consumption of the ice-making device. This embodiment can be used as an energy-saving mode of the ice-making device.

[0038] In one embodiment, the workflow of the ice-making device includes an ice-making workflow S3, and the ice-making workflow S3 includes an S31 liquid injection process and an S32 ice-making process. Controlling the heating device to perform a heating operation includes: controlling the heating device to perform a heating operation in both the S31 liquid injection process and the S32 ice-making process. The heating device is controlled to perform heating in both the S31 liquid injection process and the S32 ice-making process, and the use of a liquid injection pipe with poor thermal conductivity can be allowed. Even if the thermal conductivity of the liquid injection pipe is poor, this embodiment can ensure that the liquid injection pipe is not frozen. And energy consumption is saved to the maximum extent. For example, the ice-making device is installed in the freezer compartment of the refrigerator, and the liquid injection pipe includes a water connection assembly for connecting with an external water pipe. In order to solve the problem of the ice-making device liquid injection pipe passing through the back of the refrigerator body, the commonly used aluminum tube with good thermal conductivity can be replaced with a plastic hose with general thermal conductivity. The solution of this embodiment can ensure the temperature of the plastic hose and prevent the plastic hose from being frozen. The working process of the ice making device is a cycle of S31 liquid injection process and S32 ice making process. Since the heating operation is performed in each cycle, it can be avoided that frozen ice remains in the liquid injection pipe before the water injection process, thereby affecting the ice making effect.

[0039] In another embodiment, the heating device is controlled to perform the heating operation throughout the S31 injection process, and the heating device is controlled to perform the heating operation in the S32 ice making process within the set duration. The heating operation is performed in the S32 ice making process in order to reserve the time for the injection pipe to be back-pumped after the S31 injection process is completed, to extract the water in the injection pipe, to minimize the water in the injection pipe, and to prevent the water from freezing in a large area in the injection pipe. In addition, it may be because the heating device was not turned on in the previous round of the S32 refrigeration process, and the heating device did not completely melt the ice in the injection pipe during the water injection process. Some ice is still left in the injection pipe, which will slow down the water injection process, resulting in the water injection not being completed after the set injection process is completed. Therefore, after the set injection process is completed, it is also possible to reserve time to detect whether the water injection is completed, and to inject all the required water into the ice tray, which is carried out simultaneously with the ice making process. The duration set here can be about 30s.

[0040] In one embodiment, please refer to Figure 1 and Figure 3 In the scheme of turning off the heating device after the injection of water into the injection pipe is completed, before the S31 injection process, it also includes: S30 controlling the heating device to preheat the injection pipe. The injection pipe that is frozen during the S31 ice-making process can be thawed here to ensure smooth water injection. The preheating time can be 8 to 10 minutes. The heating process of the heating device can be 100% continuously turned on, or it can be controlled to turn on the first time within a fixed cycle time, which is not limited here. In this embodiment, the entire S3 ice-making workflow includes S30 controlling the heating device to preheat the injection pipe, S31 injection process, and S32 ice-making process, which are cyclically performed.

[0041] In one embodiment, when the ice making device needs to be turned on, before the ice making workflow of the first round S3, the liquid injection pipe needs to be preheated by a heating device. The preheating can be about 10 minutes to thaw the ice formed in the liquid injection pipe when the ice making device is in the closed state. This is applicable to the ice making method of any of the above ice making devices. After the preheating is completed, the cycle of the S3 ice making workflow is entered. In this embodiment, the ice making device can be arranged in the freezer compartment of the refrigerator, and the refrigerator provides the cold air required for ice making. When the ice making device is in the closed state, the liquid injection pipe may freeze the remaining water into ice. Therefore, it is necessary to preheat before the S3 ice making workflow after the ice making device is turned on. Different from the preheating of the liquid injection pipe by controlling the heating device in S30 in the ice making workflow above, the preheating in this embodiment is only carried out after the ice making device is turned on, and then the ice making device enters the S3 ice making workflow.

[0042] In one embodiment, please refer to Figure 1 and 4 , the ice making device process further includes an ice making device closing process, and the ice making device closing process includes:

[0043] Receiving a user signal to close the ice making device, and judging whether the ice making device is in the liquid injection process;

[0044] When the ice making device is in the liquid injection process, control the heating device to close after waiting for a second duration;

[0045] Wherein the second duration is greater than the duration required for the liquid injection process.

[0046] The user can close the ice making device on the large screen or manually. When the ice making device to be closed is in the liquid injection process, since the ice making device needs to be initialized in S1 before being restarted, that is, shaken to judge whether the position of the ice tray is appropriate. If there is remaining water in the ice tray, it may splash in the ice making device during the shaking of the S1 ice making device initialization, affecting the use of the ice making device. Therefore, when closing the ice making device, it is necessary to wait until a new round of ice making is completed before closing the ice making device. For the control of the liquid injection pipe heating device, only the liquid injection process in the last round of ice making needs to be waited for to end the heating operation. The second duration can be about 10s.

[0047] Therefore, the solution of this embodiment can wait for the second duration after receiving the signal to close the ice making device, so that the ice making device to be closed completes the water injection in the last round of ice making, preventing the ice making device from leaving liquid residues in the ice tray due to the incomplete last round of ice making, which affects the use of the ice making device later.

[0048] In one embodiment, the ice-making device includes at least two sub-ice-making devices, which can make ice of different sizes. When one of the ice-making devices needs to be turned off, the ice-making device shutdown process includes:

[0049] Receiving a signal from the user to turn off one of the sub-ice-making devices, and determining whether any sub-ice-making device is in the liquid injection process;

[0050] When a sub-ice-making device is in the liquid injection process, control the heating device to turn off after waiting for a third time period;

[0051] Wherein the third time period is greater than the sum of the liquid injection process required time periods of all sub-ice-making devices.

[0052] When multiple sub-ice-making devices inject water simultaneously, it will cause a large deviation in the water injection amounts of multiple sub-ice-making devices. Therefore, multiple sub-ice-making devices cannot inject water simultaneously. When one of the sub-ice-making devices needs to be turned off, it is necessary to wait for the sub-ice-making device to be turned off to complete the last round of ice making. If there are other sub-ice-making devices injecting water at this time, the sub-ice-making device to be turned off first waits for the other ice-making devices to complete water injection, and then the sub-ice-making device to be turned off injects water. After the sub-ice-making device to be turned off completes water injection, the heating device on the liquid injection pipe is turned off. Therefore, the third time period is the longest reserved water injection time for the ice-making device. After waiting for all other sub-ice-making devices to complete water injection, it is the turn of the sub-ice-making device to be turned off to inject water. Therefore, the third time period is set to be greater than the sum of the liquid injection process required time periods of the sub-ice-making devices. This embodiment can ensure that turning off one of the sub-ice-making devices does not affect the use of other sub-ice-making devices, and the third time period can be about 30s.

[0053] In one embodiment, there are two sub-ice-making devices, namely a first sub-ice-making device and a second sub-ice-making device. First, control the liquid injection pipe to inject water into the ice-making tray. Among them, when the first sub-ice-making device and the second sub-ice-making device are making ice simultaneously in the tray type, when the second sub-ice-making device needs to inject water, if the liquid injection pipe injects water into the first sub-ice-making device, then control the liquid injection pipe not to inject water into the second sub-ice-making device, and control the second sub-ice-making device to wait. If the liquid injection pipe does not inject water into the first sub-ice-making device, then control the liquid injection pipe to inject water into the second sub-ice-making device.

[0054] After that, control the ice-making device after water injection to make ice. In this way, under the module where the first sub-ice-making device and the second sub-ice-making device make ice simultaneously, when the second sub-ice-making device needs water injection, if the liquid injection pipe is injecting water into the first sub-ice-making device at this time, control the liquid injection pipe not to inject water into the second sub-ice-making device, and control the second sub-ice-making device to wait. If the liquid injection pipe is not injecting water into the first sub-ice-making device at this time, then control the liquid injection pipe to inject water into the second sub-ice-making device. And make ice for the ice-making tray block after water injection. Thus, the water injection of the first sub-ice-making device and the second sub-ice-making device is staggered, avoiding a large deviation in the water injection volume between the first sub-ice-making device and the second sub-ice-making device when injecting water simultaneously, improving the quality of ice making, and thus improving the user experience.

[0055] Understandably, in some other embodiments, when the first sub-ice-making device and the second sub-ice-making device are making ice in a tray type simultaneously, when the first sub-ice-making device needs water injection, if the liquid injection pipe is injecting water into the second sub-ice-making device, control the liquid injection pipe not to inject water into the first sub-ice-making device, and control the first sub-ice-making device to wait. If the liquid injection pipe is not injecting water into the second sub-ice-making device, then control the liquid injection pipe to inject water into the first sub-ice-making device.

[0056] In one embodiment, each sub-ice-making device is provided with a liquid injection pipe and a heating device; when a sub-ice-making device is in the liquid injection process, control the heating device to wait for a third duration and then turn off, including controlling the heating device of the sub-ice-making device that receives the turn-off signal to turn off. When the ice-making device includes multiple sub-ice-making devices, any sub-ice-making device can be turned off separately. Here, control the heating device of the sub-ice-making device that needs to be turned off, and turn off the heating device after ensuring that the water injection of the sub-ice-making device that needs to be turned off is completed. It does not affect the water injection and ice-making processes of other sub-ice-making devices, and other sub-ice-making devices can continue to make ice.

[0057] In one embodiment, the first temperature is 1°C, and the first set value is 5%-10%. That is, for every degree decrease in the temperature inside the ice-making device based on the reference temperature value, the startup rate of the heating device increases by 5%-10% based on the initial startup rate, which can be 5%, 6%, 7%, 8%, 10%, etc. Taking 5% as an example, set the reference temperature value to -18°C and the initial startup rate to N%. When the temperature inside the ice-making device is -19°C, the startup rate of the heating device increases by 5%. That is, the startup rate is (N - (T + 18) * 5)%, and the current temperature is T.

[0058] In one embodiment, the ice-making device may include two sub-ice-making devices, namely, a first ice-making device for making larger-sized ice cubes and a second ice-making device for making smaller-sized ice cubes. The first ice-making device needs to be configured with a liquid injection pipe having a smaller diameter, and the second ice-making device needs to be configured with a liquid injection pipe having a larger diameter. This is because the ice tray of the second ice-making device is smaller and it is prone to splashing water during the water injection process. Therefore, by designing the diameter of the liquid injection pipe to be larger, the flow rate of the water injection can be slowed down and the splashing of water can be reduced. Relatively speaking, the splashing phenomenon of the first ice-making device is not as serious as that of the second ice-making device. Therefore, the diameter of the first ice-making device can be designed to be relatively smaller. For example, the diameter of the first ice-making device is designed to be about 4 mm, and the startup rate of the first ice-making device can be 5%-8%; the diameter of the second ice-making device is designed to be about 6 mm, and the startup rate of the second ice-making device can be 8%-10%.

[0059] Taking an ice-making device including a first ice-making device and a second ice-making device as an example, after the ice-making device is turned on, the heating device preheats the liquid injection pipe for 10 minutes, sets the reference temperature value to -18°C, the initial startup rate is N%, the first temperature is 1°C, the first set value is 5%, the second duration is 10 s, and the third duration is 30 s. The working process of the entire ice-making device can be the following process.

[0060] Please refer to Figure 1 and Figure 2 , after the ice-making device is turned on, first perform the S1 ice-making device initialization operation, and then in step S2, the heating device preheats the liquid injection pipe for 10 minutes. At the same time, the startup rate of the heating device is dynamically adjusted according to the temperature, and the startup rate always satisfies (N - (T + 18) * 5)%. After the preheating of the liquid injection pipe is completed, the ice-making device enters the S3 ice-making working process. The S3 ice-making working process includes a cycle of S31 liquid injection process and S32 ice-making process. During the entire ice-making working process, the heating device is always turned on to heat the liquid injection pipe and at the same time dynamically adjust the startup rate.

[0061] In the energy-saving mode of the ice-making device, in the S1 ice-making working process, the heating device of the liquid injection pipe is turned on throughout the water injection process, and after the water injection is completed, the heating device is turned on for another 30 s and then turned off. These 30 s are carried out simultaneously with the ice-making process. And before the next water injection, control the heating device of the liquid injection pipe to preheat the liquid injection pipe for 10 minutes. Therefore, in the energy-saving mode, the ice-making working process refers to Figure 3 , which is a cycle of S30 controlling the heating device to preheat the liquid injection pipe, S31 liquid injection process, and S32 ice-making process.

[0062] Please refer to Figure 4, when it is necessary to turn off the ice-making device, the ice-making device enters the heat input ice-making device shutdown process S4. Assuming that it is necessary to turn off the first ice-making device, the ice-making device shutdown process includes: step 401 to turn off the first ice-making device, and then it is necessary to determine in step 402 whether there is an ice-making device in the water injection process. When there is an ice-making device in the water injection process, enter step 403 and wait for 30s. These 30s include 20s for waiting for the second ice-making device to complete water injection and a second duration of 10s for waiting for the first ice-making device to complete water injection. Then enter step 404 to turn off the liquid injection pipe heating device of the first ice-making device to ensure that the liquid injection process in the last round of ice-making work process ends, and then the heating device can be turned off. The same applies when turning off the second ice-making device. In the energy-saving mode of the ice-making device, the shutdown process of the ice-making device is the same as the above process.

[0063] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
