Figure 12 is a structural diagram of a refrigeration system of a refrigerator according to some embodiments.

In some embodiments, as shown in Figure 12, refrigerator 1000 further includes a refrigeration system 600. The refrigeration system 600 includes a compressor 610, a condenser 620, an anti-condensation pipe 630, a filter 640, a capillary tube 650, an evaporator 660, a gas-liquid separator 670, a connecting pipe 680, and a refrigerant flowing in the connecting pipe 680. The working process of the refrigeration system 600 includes a compression process, a condensation process, a throttling process and an evaporation process. The compressor 610, the condenser 620, the anti-condensation pipe 630, the filter 640, the capillary tube 650, the evaporator 660 and the gas-liquid separator 670 are connected through a connecting pipeline 680.

The compression process includes: when the refrigerator 1000 is powered on, the compressor 610 starts to work. The low-temperature, low-pressure refrigerant is sucked into the compressor 610, compressed into a high-temperature, high-pressure superheated gaseous refrigerant in the cylinder of the compressor 610, and then discharged to the condenser 620.

The condensation process includes: the high-temperature and high-pressure superheated gaseous refrigerant dissipates heat in the condenser 620 and is first cooled into normal-temperature and high-pressure saturated steam, and then further cooled into a saturated liquid. The pressure of the refrigerant during the condensation process is almost unchanged.

The throttling process includes: the saturated liquid filters out moisture and impurities through the filter 640 and then flows into the capillary tube 650. The capillary tube 650 performs throttling and decompression, so that the refrigerant becomes wet vapor at normal temperature and low pressure.

The evaporation process includes: normal-temperature, low-pressure wet vapor absorbs heat and vaporizes in the evaporator 660 to lower the temperature of the evaporator 660 and its surrounding environment, and turn the refrigerant into a low-temperature, low-pressure gas. The refrigerant discharged from the evaporator 660 passes through the gas-liquid separator 670 and then returns to the compressor 610 .

It can be understood that by repeatedly performing the above process, the refrigeration system 600 can transfer the heat inside the refrigerator 1000 to the outside of the refrigerator 1000, thereby achieving the purpose of cooling.

Energy conversion is performed through the state change of the refrigerant, and the heat inside the refrigerator 1000 is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator 1000. When the evaporator 660 is disposed on the wall of the refrigeration chamber 101, the refrigerator 1000 is a direct-cooling refrigerator; when the evaporator 660 is disposed in the air duct of the refrigerator 1000, the refrigerator 1000 is an air-cooling refrigerator.

Figure 13 is a block diagram of a refrigerator according to some embodiments.

In some implementations, as shown in FIG. 13 , the refrigerator 1000 further includes a controller 500 , a heating component 700 , a water filling component 800 and a detection component 900 . The controller 500 is configured to send signals to the ice maker assembly 200 to implement a predetermined program. The heating assembly 700 is disposed below the ice making tray 220 and is configured to heat the ice making tray 220 . The water filling assembly 800 is configured to fill water into the ice making tray 220 . The detection component 900 is configured to detect the amount of ice in the ice storage box 400 . The heating component 700, the water filling component 800 and the detection component 900 can respectively execute the predetermined program. The predetermined program includes a water filling program, an ice making program, an ice removing program, etc. (the water filling program, ice making program, ice removing program, etc. will be described below).

In the refrigerator 1000 provided by some embodiments of the present disclosure, the controller 500 is configured to control the operation of the first motor 330 to drive the first ice-turning rod 310 to rotate, and then control the first motor 330 to stop running to cause the first ice-turning rod 310 to rotate. The rod 310 stops rotating, and then controls the second motor 340 to run to drive the second ice turning rod 320 to rotate. The first ice block 11 and the second ice block 12 will be disconnected at the connection point under the action of different forces, thereby reducing the adhesion of the ice blocks.

Some embodiments of the present disclosure also provide a method for controlling a refrigerator. The method for controlling the refrigerator can be applied to the above-mentioned refrigerator 1000 and can be executed by the controller 500 . The controller 500 sends signals to the ice maker assembly 200 to implement a work cycle of the ice maker assembly 200 . The working cycle of the ice making machine assembly 200 includes: initialization and self-test procedures, water filling procedures, ice making procedures, detection procedures, heating procedures and ice turning procedures.

The working cycle of the ice making machine assembly 200 will be described below with reference to FIG. 14 and FIG. 15 as an example.

Figure 14 is a flowchart of steps performed by a controller in accordance with some embodiments.

In some embodiments, as shown in Figure 14, after the refrigerator 1000 is powered on and the ice maker is started After assembly 200, the controller 500 is configured to perform steps 111 to 116.

In step 111, the ice turning component 300 is controlled to perform initialization and self-test procedures.

For example, when the ice machine assembly 200 is powered on, the controller 500 controls the ice turning assembly 300 to perform an initialization self-test procedure.

The initialization self-test procedure includes the ice turning assembly 300 performing an empty ice scraping action, and the empty ice scraping action is performed according to the following ice turning procedure (eg, step 116).

In step 112, the water filling component 800 is controlled to execute the water filling procedure.

For example, when the controller controls the water filling assembly 800 to inject water into the ice making tray 220, the water flows to each ice slot 2200 through the gap 223 until the water fills all the ice slots 2200 in the ice making tray 220, and the water filling assembly 800 completes the water filling. program.

In step 113, the ice making machine assembly 200 is controlled to execute an ice making program.

For example, the controller 500 controls the ice making machine assembly 200 to provide cooling energy to the ice making chamber 102 to cause the water in the ice making tray 220 to freeze into ice cubes, and the ice making machine 200 completes the ice making program.

It should be noted that when the temperature of the ice making tray 220 detected by the temperature sensor reaches a preset temperature and the time for maintaining the preset temperature reaches a preset time, the controller 500 determines that the temperature in the ice making tray 220 is The water has frozen. The preset temperature may be a temperature below zero. For example, the preset temperature is -15° to -12°. The preset time may be the time for the ice making machine assembly 200 to make ice. For example, the preset time is any value within a fourth preset range, for example, the fourth preset range is 30 minutes to 90 minutes. For example, the preset time is 30 minutes, 60 minutes or 90 minutes. The preset time can be set according to the ice making speed and the quality of the ice cubes.

In step 114, the detection component 900 is controlled to execute the detection program.

For example, after completing the water filling program and the ice making program, the controller 500 controls the detection component 900 to detect the amount of ice in the ice storage box 400. When the detection component 900 detects that the ice in the ice storage box 400 is not full, the controller 500 controls the detection component 900 to detect the amount of ice in the ice storage box 400. The ice machine 200 is ready to perform a de-icing operation. The de-icing operation includes a heating procedure and an ice-turning procedure.

It should be noted that when the ice in the ice storage box 400 is not full, it may mean that the height of the ice does not reach the height of the ice storage box 400 . When the ice storage box 400 is full of ice, even if the ice making machine assembly 200 completes ice making, the ice cubes still stay in the ice slot 2200. If the ice turning assembly 300 performs ice turning, the ice cubes will be stuck in the ice outlet channel 251. Therefore, when the ice storage box 400 is full of ice, the ice turning assembly 300 is usually unable to perform the ice removal operation.

In step 115, the heating component 700 is controlled to perform a heating program.

For example, when the ice machine 200 completes ice making and detects that the ice storage box 400 is not full of ice, the controller 500 controls the heating component 700 to perform the heating program, and separates the ice cubes from the ice tray 220 through thawing. After heating to the second preset temperature, the ice turning component 300 is controlled to perform the ice turning program. It should be noted that the second preset temperature is a preset value, and the second preset temperature can be adjusted according to the ice mass, pressure, etc., which is not disclosed in this disclosure.

In step 116, the ice turning assembly 300 is controlled to execute the ice turning procedure.

For example, the controller 500 controls the ice turning assembly 300 to stir the ice cubes in the ice making tray 220 .

Figure 15 is another flowchart of steps performed by a controller in accordance with some embodiments.

In some embodiments, as shown in Figure 15, step 116 includes step 1161 and step 1162.

In step 1161, the first motor 330 is controlled to run to drive the first ice turning rod 310 to rotate the first preset angle F2 in the first direction (target direction), and the second motor 340 is controlled to stop running, so that the second ice turning rod 310 rotates at the first preset angle F2 in the first direction (target direction). The ice rod 320 stops rotating.

For example, the first direction is a clockwise direction (P direction shown in FIG. 17).

In step 1162, the first motor 330 is controlled to drive the first ice-turning rod 310 to continue rotating in the first direction to remove the ice cubes in the first ice slot 221, and the second motor 340 is controlled to drive the second ice-turning rod 310. The rod 320 rotates along the first direction from the first initial position to remove the ice cubes in the second ice slot 222 .

In some embodiments, when the first ice-turning rod 310 rotates to the first preset angle F2, the controller 500 controls the first motor 330 to drive the first ice-turning rod 310 to continue to rotate in the first direction, and The second motor 340 is controlled to drive the second ice turning rod 320 to rotate synchronously with the first ice turning rod 310 .

In some embodiments, when the first ice-turning rod 310 rotates to the first preset angle F2, the controller 500 controls the second ice-turning rod 320 to rotate synchronously with the first ice-turning rod 310 to the second preset angle F3, Continue to control the first ice turning rod 310 and the second ice turning rod 320 to rotate synchronously for at least one turn.

In some embodiments, the first preset angle F2 is any angle within the first preset range. For example, the first preset range is 50° to 70° (50°≤F2≤70°). For example, the first predetermined angle F2 is 50°, 60° or 70°. The second predetermined angle F3 is any angle within the second preset range. For example, the second preset range is 250° to 270° (250°≤F3≤270°). For example, the second predetermined angle F3 is 250°, 260° or 270°.

In some embodiments, when the ice is not turned over, the first dialing part 312 is located above the first ice chute 221 and the second dialing part 322 is located above the second ice chute 222 . For example, as shown in Figure 10, the first dialing part 312 is in a horizontal position, and the initial angle F1 between the first dialing part 312 and the second dialing part 322 is any angle within the third preset range, For example, the third preset range is 150° to 180° (150°≤F1≤180°). For example, the initial included angle F1 is 150°, 155° or 180°.

Taking the initial included angle F1 as 155°, the first predetermined angle F2 as 60°, and the second predetermined angle F3 as 265° as an example, the controller 500 controls the ice turning assembly 300 to execute the ice turning procedure.

When the ice is not turned, the initial position of the first dialing part 312 is set as the second initial position. The initial included angle F1 between the first dialing part 312 and the second dialing part 322 is 155°. The initial position of the second dialing part 322 is set as the third initial position.

Figure 16 is yet another flowchart of steps performed by a controller according to some embodiments.

In some embodiments, as shown in Figure 16, the controller is configured to perform steps 211 to 214.

In step 211, the first motor 330 is controlled to drive the first ice turning rod 310 to rotate 60° along the first direction, and the second ice turning rod 320 is controlled to stop rotating.

For example, the controller 500 controls the first motor 330 to drive the first ice turning rod 310 to rotate 60° along the first direction, and controls the second ice turning rod 320 to stop rotating. For example, the second ice turning rod 320 is controlled to remain still.

Figure 17 is a structural diagram of the first ice turning rod rotating at a first predetermined angle according to some embodiments.

When the ice turning assembly 300 is turning ice, the first ice turning rod 310 rotates 60° in the clockwise direction to drive the first turning part 312 to rotate 60°, and the second ice turning rod 320 remains stationary. In this case, as shown in FIG. 17 , the first target included angle F4 between the first dialing part 312 and the second dialing part 322 is 95°. The position of the first dialing part 312 at this time is set as the target position, and the angle between the target position and the horizontal plane is 60°. The target position is conducive to the first dialing part 312 dialing the first ice cube 11 .

When the first dialing part 312 rotates 60°, the first dialing part 312 acts on the ice cubes in the first ice tank 221, and the second dialing part 322 acts on the ice cubes in the second ice tank 222. The ice cubes in the adjacent first ice slot 221 and the ice cubes in the second ice slot 222 are disconnected at the connection point (notch 223) to form the first ice cube 11 (ie, as shown in Figure 17 An arcuate shape enclosed by a solid line) and the second ice block 12 (ie, an arcuate shape enclosed by a dotted line as shown in Figure 17). During this process, the first ice cube 11 is moved. The first ice cube 11 corresponds to the ice cube in the first ice slot 221 . The second ice cube 12 corresponds to the ice cube in the second ice slot 222 .

In step 212, the first motor 330 is controlled to continue to drive the first ice-turning rod 310 to rotate in the first direction, and the second motor 340 is controlled to drive the second ice-turning rod 320 to synchronize with the first ice-turning rod. Rotate 265° in the first direction.

For example, the controller 500 controls the first motor 330 to continue driving the first ice turning pole 310 along the first Rotate in one direction, and control the second motor 340 to drive the second ice turning rod 320 to synchronize with the first ice turning rod to rotate 265° in the first direction.

Figure 18 is a structural diagram of the second ice turning rod rotating at a second predetermined angle according to some embodiments.

After the second motor 340 drives the second ice-turning rod 320 and the first ice-turning rod 310 to rotate 265° in the first direction synchronously, as shown in Figures 17 and 18, due to the second ice-turning rod 320 and the first ice-turning rod 310, The ice-turning pole 310 rotates synchronously. Therefore, the second target included angle F5 between the first dialing part 312 and the second dialing part 322 is the same as the first target included angle F4, and the second target included angle F5 is the same as the first target included angle F4. The target angle F4 is 95° respectively. In addition, since the second ice turning rod 320 rotates 265° along the first direction, it is equivalent to the second ice turning rod 320 rotating 95° along the second direction. For example, the second direction is a counterclockwise direction (Q direction in Figure 17). In this way, as shown in Figures 17 and 18, after the second ice turning rod 320 rotates 95° along the second direction, the second dialing part 322 rotates to the target position of the first dialing part 312, that is to say , the position of the second dialing part 322 in Figure 18 is the position of the first dialing part 312 in Figure 17, so that it is convenient for the second dialing part 322 to dial the second ice cube 12.

It should be noted that the second ice-turning rod 320 and the first ice-turning rod 310 rotate 265° in the first direction synchronously. This angle is conducive to the first ice-turning rod 310 completely pulling out the first ice cube 11 .

During this process, the first dialing part 312 first pulls the first ice cube 11 out of the first ice slot 221 , and then the first ice cube 11 slides down into the ice storage box 400 through the guide part 250 . After that, the second turning part 322 turns up the second ice cube 12 .

In step 213, the first motor 330 is controlled to drive the first ice turning rod 310, and the second motor 340 drives the second ice turning rod 320 to continue to rotate synchronously in the first direction until the first ice turning rod 310 rotates a total of 720 °.

For example, the controller 500 controls the first motor 330 to drive the first ice-turning rod 310, and the second motor 340 to drive the second ice-turning rod 320 to continue to rotate synchronously in the first direction until the first ice-turning rod 310 rotates a total of 720 °. That is to say, the first ice turning rod 310 rotates twice, and the first dialing part 312 returns to the second initial position.

In step 214, the second motor 340 is controlled to drive the second ice turning rod 320 to rotate another 60° along the first direction.

For example, when the first ice turning rod 310 has rotated a total of 720°, the second ice turning rod 320 has rotated 660°, and the second toggle part 322 has moved the second ice cube 12 to the guide part 250 and then slid down to the ice storage. 400 in box. After that, the controller 500 controls the second motor 340 to drive the second ice turning rod 320 to rotate another 60° along the first direction. At this time, the second ice turning rod 320 has rotated a total of 720°. That is to say, the second ice turning rod 320 has rotated 720° in total. Ice pole 320 After two turns, the second dialing part 322 returns to the third initial position.

In this way, when the second ice turning rod 320 and the first ice turning rod 310 rotate twice respectively, the second ice turning rod 320 and the first ice turning rod 310 respectively complete two ice turning actions, and the second ice chute 222 and The ice cubes in the first ice trough 221 are turned over once to remove the ice cubes in the ice making tray 220 . The first motor 330 drives the first ice-turning rod 310 to rotate twice, and then returns to the second initial position. The second motor 340 drives the second ice-turning rod 320 to rotate two times, and then returns to the third initial position. Wait for the next time to repeat the above ice turning procedure.

It should be noted that the previous article takes as an example that the second ice turning rod 320 and the first ice turning rod 310 rotate twice respectively to meet the ice turning requirements and the duration of the ice turning procedure. Of course, the second ice turning rod 320 The first ice turning rod 310 can also be set to rotate more than two times to completely turn the ice, which is not limited in this disclosure.

In the ice-turning program, the ice-turning action can be controlled through software and a position switch (Travel Switch), and the completion of the ice-turning and the stop positions of the first ice-turning rod 310 and the second ice-turning rod 320 can be determined.

In the control method of the refrigerator provided by some embodiments of the present disclosure, the first ice cube 11 and the second ice cube 12 can be disconnected through the control of the controller 500, and the ice cubes can be de-iced sequentially in two times, which is beneficial to reducing the adhesion of the ice cubes. Phenomenon. In addition, removing ice in sequence can reduce the number of ice blocks passing through the ice outlet channel 251, which is helpful to solve the fault caused by ice blocks getting stuck in the ice outlet channel 251.

Those skilled in the art will understand that the disclosed scope of the present invention is not limited to the specific embodiments described above, and that certain elements of the embodiments may be modified and replaced without departing from the spirit of the application. The scope of the application is limited by the appended claims.
