[0002] A refrigerator uses a refrigeration system to maintain a low temperature inside it. It can not only store food but also make ice by setting an ice-making device, which greatly facilitates the user's need for ice cubes. As the user's requirements for the size and shape of ice cubes increase, more and more refrigerators are equipped with multiple ice-making devices of different specifications to meet the user's needs for the size and shape of ice cubes.

[0003] In the related art, a water injection device is usually provided inside the refrigerator, and water is injected into multiple ice-making devices through the water injection device, but this may result in insufficient water injection amounts between the multiple ice-making devices. Summary of the Invention

[0057] With the continuous improvement of people's living standards, refrigerators have become a necessity in people's lives. Refrigerators use refrigeration to maintain a low temperature inside, which can not only preserve food, but also make ice by setting up an ice-making device, greatly facilitating the user's need for ice cubes. As the user's requirements for the size and shape of ice cubes increase, more and more refrigerators are equipped with multiple ice-making devices of different specifications to meet the user's needs for the size and shape of ice cubes. Currently, there are a wide variety of refrigerators and brands, giving consumers a lot of choices. How to win the favor of consumers and enhance product competitiveness has become an issue that refrigerator manufacturers increasingly pay attention to.

[0058] In the related art, a liquid injection device is usually provided inside the refrigerator, and water is injected into multiple ice-making devices simultaneously through the liquid injection device. However, the R & D personnel found in the practice of the related art that in a refrigerator with multiple ice trays, the refrigerator usually sets up one water pump to inject liquid for multiple ice trays. And the injection time is set according to the time required for individual ice tray injection. If injected simultaneously, since the flow rate that the water pump can provide per unit time is fixed, simultaneous injection will result in insufficient liquid injection volume for each ice mold.

[0059] Based on this, the present disclosure provides an ice-making method for a refrigerator 1 and the refrigerator 1. This ice-making method can be used when multiple ice trays 110 need to make ice, avoiding insufficient liquid injection between the multiple ice trays 110 and improving the user experience of the refrigerator 1 applying this ice-making method.

[0060] As Figure 1 and Figure 2 shown, the present application provides a refrigerator 1, including a cabinet device 10, a compressor 20, a condenser 30, an evaporator 40, and an expansion valve 50. The cabinet device 10 includes a cabinet assembly 11, a freezer compartment 13, a refrigerating compartment 14, and a door assembly 12. The freezer compartment 13 and the refrigerating compartment 14 are respectively arranged in the cabinet assembly 11. The door assembly 12 includes a first door 12a and a second door 12b. The first door 12a is rotatably connected to the cabinet assembly 11 to open or close the freezer compartment 13. The second door 12b is rotatably connected to the cabinet assembly 11 to open or close the freezer compartment 13. The compressor 20, the condenser 30, the evaporator 40, and the expansion valve 50 are respectively arranged in the cabinet assembly 11, and at least part of the evaporator 40 is arranged in the freezer compartment 13.

[0061] Combined with Figure 3 shown, when the refrigerator 1 operates, the compressor 20 outputs high-temperature and high-pressure gaseous refrigerant and transports it to the condenser 30, where the high-temperature and high-pressure gaseous refrigerant is condensed into medium-temperature and high-pressure refrigerant through the condenser 30. The medium-temperature and high-pressure refrigerant undergoes the expansion throttling effect of the expansion valve 50, causing the pressure and temperature of the refrigerant to further decrease, and flowing out of the expansion valve 50 as low-temperature and low-pressure liquid refrigerant to the evaporator 40. The low-temperature and low-pressure liquid refrigerant evaporates into gaseous refrigerant in the evaporator 40. And at least part of the evaporator 40 is arranged in the freezer compartment 13, enabling the refrigerant to absorb a large amount of heat in the freezer compartment 13 during the evaporation process, thereby reducing the temperature in the freezer compartment 13 and facilitating the use of the freezer compartment 13 to freeze items, achieving the refrigeration of the refrigerator 1. The refrigerant coming out of the evaporator 40 is replenished back to the compressor 20 to form a refrigerant circuit. In this way, the refrigerant continuously circulates in the refrigerant circuit to maintain the freezing environment (e.g., less than -1°C) in the freezer compartment 13.

[0062] Referring back to Figure 2 shown, there is an air duct 15 between the refrigerating compartment 14 and the freezer compartment 13, facilitating the transportation of part of the cold air in the freezer compartment 13 to the refrigerating compartment 14 through the air duct 15 to reduce or maintain the low-temperature environment (e.g., 2°C - 8°C) in the refrigerating compartment 14.

[0063] As Figure 2As shown, in some embodiments, along the height direction of the refrigerator 1, the freezer compartment 13 is arranged below the refrigerating compartment 14. The refrigerator 1 further includes a first blower (not labeled) provided in the cabinet assembly 11. The air inlet end or the air outlet end of the first blower is communicated with the air duct 15 for delivering a part of the cold air in the freezer compartment 13 into the refrigerating compartment 14.

[0064] As Figure 2 shown, the height direction of the refrigerator 1 is the Z-axis direction.

[0065] In some embodiments, the outer sidewall of the freezer compartment 13 is covered with a heat-insulating layer (not shown) to separate the evaporator 40 from the compressor 20 and the condenser 30.

[0066] In some embodiments, the outer sidewall of the freezer compartment 13 is covered with a heat-insulating layer (not shown).

[0067] In some embodiments, the refrigerator 1 further includes an air-cooled heat dissipation assembly (not shown) provided in the cabinet assembly 11, and the air-cooled heat dissipation assembly can at least dissipate heat from the condenser 30.

[0068] In some embodiments, the cabinet assembly 11 further includes a fresh-keeping compartment provided in the cabinet assembly 11. Along the height direction of the refrigerator 1, the fresh-keeping compartment is arranged between the refrigerating compartment 14 and the freezer compartment 13.

[0069] To meet the user's need for using ice cubes, as Figure 4 shown, in some embodiments, the refrigerator 1 further includes an ice-making device 60 for making ice cubes. The ice-making device 60 includes an ice-making component 100 and a liquid-injecting component 200. The ice-making component 100 includes an ice tray 110 provided in the freezer compartment 13. The liquid-injecting component 200 is used to inject the liquid required for making ice cubes into the ice tray 110.

[0070] It should be noted that Figure 4 the first door 12a of the shown refrigerator 1 is open and not shown, and the second door 12b is in the closed state.

[0071] Optionally, in some embodiments, the liquid-injecting component 200 includes a water receiving assembly communicated with an external liquid injection pipe 220.

[0072] As Figure 4 shown, in an example, the liquid-injecting component 200 includes a liquid storage container 210 and a liquid injection pipe 220. The liquid storage container 210 is arranged in the refrigerating compartment 14. One end of the liquid injection pipe 220 is communicated with the liquid storage container 210, and along the height direction of the refrigerator 1, the other end of the liquid injection pipe 220 is arranged above the ice tray 110.

[0073] Optionally, the liquid injection component 200 further includes a switching valve (not shown), which is disposed on at least one of the liquid storage container 210 and the liquid injection pipe 220, and is used to open the liquid injection component 200 to inject liquid into the ice tray 110, or to close the liquid injection component 200.

[0074] As Figure 4 shown, in some embodiments, the ice tray 110 is rotatably disposed in the freezing chamber 13 and has a liquid receiving state and an ice dumping state. The ice making component 100 further includes a driving assembly 120 and an ice storage container 130. The driving assembly 120 is disposed in the freezing chamber 13 and is used to drive the ice tray 110 to switch between the liquid receiving state and the ice dumping state. Along the height direction of the refrigerator 1, the ice storage container 130 is disposed below the ice tray 110. In this way, the ice storage container 130 can receive the ice cubes dumped by the ice tray 110.

[0075] It should be noted that the ice tray 110 and the driving assembly 120 can be directly or indirectly disposed in the freezing chamber 13.

[0076] As Figure 4 shown, in some embodiments, the ice making component 100 further includes a carrying assembly 140, and the carrying assembly 140 is fixed to the freezing chamber 13. The ice tray 110 is rotatably disposed on the carrying assembly 140. The driving assembly 120 is disposed on the carrying assembly 140. In this way, by integrating the ice tray 110 and the driving assembly 120 through the carrying assembly 140, the ice making component 100 can be modularly assembled in the freezing chamber 13, which is beneficial to improving the assembly efficiency of the refrigerator 1.

[0077] In some embodiments, the liquid storage container 210 is disposed on the second door 12b. In this way, the liquid storage container 210 is stored in the refrigerating chamber through the second door 12b, which is convenient for the user to take and place the liquid storage container 210. In some embodiments, ice water can also be provided for the user.

[0078] In order to facilitate the cleaning of the ice making component 100, the ice making component 100 is usually detachably connected to the refrigerator 1, and the ice tray 110 is detachably connected to the ice making component 100, so as to facilitate the removal of the ice making component 100 and the ice tray 110 for cleaning. However, when the ice tray 110 is disassembled and installed on the ice making component 100, and the ice making component 100 is installed on the refrigerator 1, there is a problem of incorrect position installation.

[0079] In order to avoid incorrect installation, in some embodiments, after the ice maker is started, it is first detected whether the started ice making component 100 and the ice tray 110 are installed in place. When the position of the ice making component 100 is incorrectly installed or the ice making component 100 is not installed at the preset position of the refrigerator 1, it will be detected that the ice making component 100 is not installed in place. When the ice tray 110 is incorrectly installed or the ice tray 110 is not installed at the required position as required, it will also be detected that the ice tray 110 is not installed in place.

[0080] Specifically, whether the ice-making component 100 and the ice tray 110 are installed in place can be detected by means of a Hall sensor, an infrared sensor, etc.

[0081] Before ice-making, the ice tray 110 needs to be filled with liquid through the liquid injection pipe 220. Since there will inevitably be residual liquid in the liquid injection pipe 220, it will cause the liquid injection pipe 220 to freeze and block the liquid injection pipe 220. Therefore, in some embodiments, the liquid injection pipe 220 is provided with a heating device, which can be, for example, a heating wire wound around the liquid injection pipe 220. Control the heating device to perform a heating operation, and control the heating device to continuously turn on for a first duration within a fixed cycle duration, and the first duration is less than the fixed cycle duration. For example, the cycle duration is 60 seconds, and the first duration is less than 60 seconds. Thereby preventing the liquid injection pipe 220 from freezing.

[0082] In some embodiments, the ice-making component 100 includes a first ice tray and a second ice tray. The liquid injection component 200 includes a valve and a water pump connected to each other. One end of the liquid injection pipe 220 is connected to the liquid storage container 210 through the valve and the water pump, and the other end of the liquid injection pipe 220 is arranged above the first ice tray and / or the second ice tray. Thereby controlling the injection of liquid into the first ice tray and / or the second ice tray by controlling the opening and closing of the valve and the water pump.

[0083] In some embodiments, the first ice tray is provided with a plurality of first ice cells, and the second ice tray is provided with a plurality of second ice cells, and the volumes between the first ice cells and the second ice cells are not equal. In this way, ice cubes of different sizes can be made through the first ice cells and the second ice cells, so that the user can select an ice tray 110 with a suitable volume according to the actual ice cube size requirement.

[0084] It should be noted that there are various specific implementations of the unequal volumes between the first ice cells and the second ice cells, including that the cross-sectional areas of the first ice cells and the second ice cells on the same plane are equal, but the heights are not equal, resulting in unequal volumes. Or the cross-sectional areas of the first ice cells and the second ice cells on the same plane are not equal, but the heights are equal, resulting in unequal volumes. Or the cross-sectional areas and heights of the first ice cells and the second ice cells on the same plane are not equal, resulting in unequal volumes. Or the shapes of the ice cubes made by the first ice cells and the second ice cells are different, resulting in unequal volumes. As long as the volumes between the first ice cells and the second ice cells can be made unequal, there is no limitation here.

[0085] In some embodiments, the refrigerator 1 further includes a control module 300 for executing the ice-making method of the refrigerator 1. Specifically, the control module 300 includes a memory and a processor. The memory is used to receive and store information. During the process of the processor running the program, it executes the ice-making method applied to the refrigerator 1.

[0086] It should be noted that the processor can be a Micro - controller Unit (MCU), a Central Processing Unit (CPU), a Digital Signal Processor (DSP), etc. In this way, with the processor, the control module 300 can control the overall operation of the ice - making process, such as operations associated with parameter acquisition, display, etc. The control module 300 can include one or more processors to execute instructions to complete the above - mentioned operations. In addition, the control module 300 can also include one or more interaction modules, such as a touch screen, operation input keys, etc., to facilitate interaction with the control device.

[0087] It should be noted that the memory is configured to store various types of data. Examples of these data include, but are not limited to, the ice - making method applied to the refrigerator 1 in the above - mentioned embodiments, and also include other refrigerator 1 control methods, etc. The memory can be implemented by any type of volatile or non - volatile storage device or a combination thereof, such as Static Random Access Memory (SRAM), Electrically Erasable Programmable Read - Only Memory (EEPROM), Erasable Programmable Read - Only Memory (EPROM), Programmable Read - Only Memory (PROM), Read - Only Memory (ROM), magnetic memory, flash memory, etc.

[0088] Figure 5 is a flowchart of the ice - making method shown in an embodiment of the present application, and this method is applied to the above - mentioned refrigerator. As Figure 2 shown, this method can include the following steps 510 to step 520:

[0089] Step 510: Control the liquid injection component to inject liquid into the ice - making component. Among them, in the simultaneous ice - making mode of the first ice tray and the second ice tray, when the second ice tray needs to be injected with liquid, if the liquid injection component injects liquid into the first ice tray, then control the liquid injection component not to inject liquid into the second ice tray and control the second ice tray to wait. If the liquid injection component does not inject liquid into the first ice tray, then control the liquid injection component to inject liquid into the second ice tray.

[0090] Step 520: Control the ice - making component after liquid injection to make ice.

[0091] Thus, when under the module where the first ice tray and the second ice tray make ice simultaneously, when the second ice tray needs to be filled with liquid, if the liquid filling component is filling the first ice tray at this time, control the liquid filling component not to fill the second ice tray, and control the second ice tray to wait. If the liquid filling component is not filling the first ice tray at this time, then control the liquid filling component to fill the second ice tray. And perform ice making on the ice making component after filling with liquid. Thus, the liquid filling of the first ice tray and the second ice tray is staggered, so that the corresponding liquid filling time can be set according to each ice tray, thereby making the liquid filling volume of each ice tray sufficient. The production quality of the ice cubes is improved, thereby enhancing the user experience.

[0092] Understandably, in some other embodiments, in the simultaneous ice making mode of the first ice tray and the second ice tray, when the first ice tray needs to be filled with liquid, if the liquid filling component is filling the second ice tray, then control the liquid filling component not to fill the first ice tray, and control the first ice tray to wait. If the liquid filling component is not filling the second ice tray, then control the liquid filling component to fill the first ice tray.

[0093] As Figure 6 shown, in some embodiments, the ice making mode further includes a single ice making mode of the first ice tray and a single ice making mode of the second ice tray. The ice making method of the refrigerator may further include the following steps 610 to step 620:

[0094] Step 610: When the ice making mode is the single ice making mode of the first ice tray, control the liquid filling component to fill the first ice tray with liquid.

[0095] Step 620: When the ice making mode is the single ice making mode of the second ice tray, control the liquid filling component to fill the second ice tray with liquid.

[0096] Thus, when the ice making mode is the single ice making mode, directly fill the ice making component with liquid through the liquid filling component, thereby improving the ice making efficiency.

[0097] As Figure 7 shown, in some embodiments, when controlling the liquid filling component to fill the ice making component with liquid, the ice making method may further include the following steps 710 to step 740:

[0098] Step 710: Control the valve to open.

[0099] Step 720: After the valve is opened, control the water pump to open and fill the ice making component with liquid.

[0100] Step 730: When the liquid filling is completed, control the water pump to close.

[0101] Step 740: After the water pump is closed, control the valve to close.

[0102] In this way, when the liquid injection component injects liquid into the ice making component, first open the valve, and then turn on the water pump to slowly increase the internal fluid pressure, thus avoiding damage to pipelines, valves, etc. caused by sudden pressure surges. When the liquid injection is completed, first control the water pump to turn off, and then close the valve, which can prevent internal pressure increase and damage to components such as pipelines and valves.

[0103] In the practice of related technologies, the R & D personnel found that the opening and closing sequence of the components in the liquid injection component will affect the overall performance of the liquid injection component and even the ice making reliability of the ice making component.

[0104] Based on this, as Figure 8 shown, in some embodiments, the ice making method may further include the following steps 810 to 870:

[0105] Step 810: Control the valve to open.

[0106] Step 820: If the opening duration of the valve reaches the fourth set duration, control the water pump to open.

[0107] Step 830: Control the water pump to rotate forward.

[0108] Step 840: If the forward rotation duration of the water pump reaches the first set duration, control the water pump to stop rotating for the second set duration.

[0109] Step 850: When the water pump stops rotating for the second set duration, control the water pump to rotate in reverse.

[0110] Step 860: After the reverse rotation duration of the water pump reaches the third set duration, control the water pump to close.

[0111] Step 870: After the closing duration of the water pump reaches the fifth set duration, control the valve to close.

[0112] Specifically, the following is a further detailed description.

[0113] In some embodiments, when controlling the water pump to open, the ice making method includes:

[0114] Control the water pump to rotate forward.

[0115] If the forward rotation duration of the water pump reaches the first set duration, control the water pump to rotate in reverse.

[0116] In this way, when the water pump is opened, control the water pump to rotate forward to inject water into the ice making device. And according to the capacity of the ice making device, set the forward rotation duration of the water pump as the first set duration. When the forward rotation duration of the water pump reaches the first set duration, the liquid injection is completed, and then control the water pump to rotate in reverse to drain the water in components such as pipelines and valves by the water pump, avoiding blockage of the liquid injection component caused by residual water freezing.

[0117] It should be noted that the range of the first set duration is 1 s to 15 s. Optionally, the first set duration is 1 s, 2 s, 3 s, 5 s, 8 s, 9 s, 10 s, 12 s, 15 s, etc.

[0118] It can be understood that the first set duration is affected by the flow rate of the liquid injection component and the capacity of the ice making component. A reasonable first set duration can be selected according to the flow rate of the liquid injection component and the capacity of the ice making component. There is no excessive limitation here.

[0119] In some embodiments, the ice making method may further include:

[0120] If the duration of the forward rotation of the water pump reaches the first set duration, control the water pump to stop rotating for the second set duration.

[0121] When the water pump stops rotating for the second set duration, control the water pump to rotate in reverse.

[0122] In this way, there is a time difference of the second set duration between the forward rotation and the reverse rotation of the water pump, avoiding damage to the water pump caused by too fast switching between the forward rotation and the reverse rotation of the water pump.

[0123] It should be noted that the range of the second set duration is 100 ms to 1000 ms. Optionally, the second set duration is 100 ms, 200 ms, 300 ms, 400 ms, 500 ms, 800 ms, 900 ms, 1000 ms, etc.

[0124] In some embodiments, the ice making method may further include: after the duration of the reverse rotation of the water pump reaches the third set duration, control the water pump to close. In this way, by setting the duration of the reverse rotation of the water pump to the third set duration and closing the water pump after the duration of the reverse rotation of the water pump reaches the third set duration. Thereby further ensuring that the water in components such as pipelines and valves is pumped dry by the water pump, avoiding blockage of the liquid injection component caused by freezing of residual moisture.

[0125] It should be noted that the range of the third set duration is 1 s to 8 s. Optionally, the third set duration is 1 s, 2 s, 3 s, 5 s, 7 s, 8 s, etc.

[0126] In some embodiments, when controlling the valve to open, the ice making method may further include: after the duration of the valve opening reaches the fourth set duration, control the water pump to open. In this way, when the duration of the valve opening reaches the fourth set duration, then control the water pump to open. To ensure that the water pump is opened after the valve is completely opened. Avoiding damage to the components inside the liquid injection component caused by opening the water pump when the valve is not opened.

[0127] It should be noted that the range of the fourth set duration is 100 ms to 500 ms. Optionally, the fourth set duration is 100 ms, 200 ms, 300 ms, 400 ms, 500 ms, and so on.

[0128] In some embodiments, controlling the water pump to close may further include: after the duration of the water pump closing reaches the fifth set duration, controlling the valve to close. In this way, when the duration of the water pump closing reaches the fifth set duration, the invention is then controlled to close. This ensures that the valve is closed only after the water pump is completely closed. It avoids closing the valve when the water pump is not fully closed, which may increase the internal pressure of the liquid injection component and cause damage to components such as pipelines and valves.

[0129] It should be noted that the range of the fifth set duration is 100 ms to 500 ms. Optionally, the fifth set duration is 100 ms, 200 ms, 300 ms, 400 ms, 500 ms, and so on.

[0130] In some embodiments, controlling the ice-making component to make ice after liquid injection may further include:

[0131] After the ice-making component finishes liquid injection, control the ice-making component to wait for a duration reaching the sixth set duration.

[0132] If the waiting duration of the ice-making component reaches the sixth set duration, make ice for the ice-making component.

[0133] In this way, after the ice-making component finishes liquid injection, controlling the ice-making component to wait for the sixth set duration is beneficial to discharging the air in the water of the ice-making component, reducing the bubbles in the water of the ice-making component after liquid injection is completed, improving the firmness of the ice cubes, and effectively improving the user experience.

[0134] Furthermore, in some embodiments, during the process of controlling the waiting duration of the ice-making component to reach the sixth set duration, vibrate the ice-making component. In this way, further discharge the air in the water of the ice-making component, and further reduce the bubbles in the water of the ice-making component.
