The refrigerator liner 19 is arranged in the cabinet 10, and the refrigerator liner 19 is provided with a freezing chamber 11. The air duct mechanism is arranged in the cabinet 10 and located between the inner wall of the cabinet 10 and the refrigerator liner 19. The side wall of the freezing chamber 11 is provided with an air duct communicating with the air duct mechanism and a first air outlet 12 of the freezing chamber 11. The ice making mechanism 20 is arranged in the freezing chamber 11, and the ice making mechanism 20 is arranged close to the first air outlet 12, and the projection of the side wall provided with the first air outlet 12 does not overlap the first air outlet. The temperature detection mechanism 30 is arranged in the freezing chamber and is used to obtain the ice making temperature of the ice making mechanism 20. The controller is connected with the temperature detection mechanism 30 and is used to control the work of the refrigerator based on the ice making temperature.

[0025] The working principle of the controller can be referred to the description below.

[0026] Among them, the temperature detection mechanism 30 can be arranged on the top wall of the freezing chamber and located directly above the ice making mechanism 20, so as to reduce the temperature detection distance of the temperature detection mechanism 30, and can ensure the influence of the liquid in the ice making mechanism 20 on the temperature detection mechanism 30, and can improve the detection accuracy of the ice making temperature.

[0027] In other embodiments, the temperature detection mechanism can also be arranged on the ice making mechanism.

[0028] The temperature detecting mechanism 30 can include a single temperature sensor or multiple temperature sensors to obtain the ice-making temperature of different ice-making areas of the ice-making mechanism 20, and the controller determines the ice-making temperature of the ice-making mechanism 20 based on the ice-making temperatures of the multiple different ice-making areas.

[0029] The refrigerator of the present embodiment is provided with the ice-making mechanism 20 in the freezing chamber 11, the ice-making mechanism 20 is arranged close to the first air outlet 12, and the projection of the ice-making mechanism 20 on the side wall of the freezing chamber 11 where the first air outlet 12 is arranged does not overlap with the first air outlet 12, so that the cold air introduced into the freezing chamber 11 from the first air outlet 12 flows parallel to the surface space of the ice-making mechanism 20, the ice-making mechanism 20 does not hinder the cold air, and does not affect the refrigeration effect of the whole freezing chamber 11, and the cold air flowing parallel to the surface space of the ice-making mechanism 20 can take away the heat of the ice-making mechanism 20, thereby realizing ice-making of the ice-making mechanism.

[0030] Optionally, the side wall of the freezing chamber 11 of the present embodiment is further provided with a second air outlet 13 in communication with the air duct, and the distance between the first air outlet 12 and the ice-making mechanism 20 is less than the distance between the second air outlet 13 and the ice-making mechanism 20. The refrigerator of the present embodiment further comprises a first air door 14, a second air door 115 and a driving mechanism, wherein the first air door 14 is arranged at the first air outlet 12 and is used to open and close the first air outlet 12; the second air door 115 is arranged at the second air outlet 13 and is used to open and close the second air outlet 13; and the driving mechanism is connected with the controller and is used to drive the first air door 14 and the second air door 115 to act under the control of the controller.

[0031] The second air outlet 13 and the first air outlet 12 jointly provide cold air for the freezing chamber. The first air outlet 12 is closer to the ice-making mechanism 20 than the second air outlet 13, and when the ice-making temperature of the ice-making mechanism 20 is higher than the first preset temperature, the controller controls the driving mechanism to drive the first air door 14 to open the first air outlet 12, and controls the driving mechanism to drive the second air door 115 to drive the second air outlet 13 to close, so that the cold air in the air duct is introduced into the freezing chamber from the first air outlet 12, thereby increasing the air outlet amount from the first air outlet 12 to the freezing chamber and improving the ice-making speed of the ice-making mechanism 20; when the ice-making temperature of the ice-making mechanism 20 is lower than or equal to the second preset temperature, it is determined that the ice-making is completed, then the controller controls the driving mechanism to drive the first air outlet 12 to remain open, and controls the driving mechanism to drive the second air door 115 to drive the second air outlet 13 to open, so that the cold air in the air duct is introduced into the freezing chamber from the first air outlet 12 and the second air outlet 13, thereby realizing uniform refrigeration of the freezing chamber.

[0032] When the ice maker needs to make ice quickly, the controller controls the second air outlet 13 to be closed, and when the ice maker does not need to make ice quickly, the controller controls the second air outlet 13 to be opened; in the ice making state and the non-ice making state, the first air outlet 12 is always open, and cold air can be supplied to the freezing chamber 11 through the first air outlet 12; the opening and closing of the second air outlet 13 can adjust the air outlet amount of the first air outlet 12, and the temperature difference fluctuation between the ice making state and the non-ice making state in the freezing chamber 11 can be reduced.

[0033] The second air outlet and the position are not limited in the application, and the second air outlet can be arranged at the upper right, lower left, lower right, and middle of the side wall.

[0034] Optionally, the ice maker 20 of the embodiment includes an ice making box 15, an ice storage box 16, and a support 17; the ice storage box 16 is arranged below the ice making box 15; the support 17 is arranged in the freezing chamber 11 and connected with the inner wall of the freezing chamber 11; and the ice making box 15 and the ice storage box 16 are arranged on the support 17.

[0035] The ice storage box 16 is arranged below the ice making box 15, so that the ice making box 15 can be manually or automatically deiced, and the ice falls into the ice storage box 16 for storage; the arrangement of the ice storage box 16 below the ice making box 15 can reduce the shielding of the ice making box 15, thereby increasing the amount of cold air introduced by the first air outlet 12 for heat exchange with the ice making box 15, increasing the heat exchange area between the ice making box 15 and the cold air near the first air outlet 12, improving the heat exchange efficiency, and further improving the ice making speed of the ice maker 20; the arrangement of the ice storage box 16 below the ice making box 15 can improve the convenience of ice storage when ice making is completed; and further, the design of the support 17 can reduce the shielding of the ice making box 15, increase the heat exchange area between the ice making box 15 and the cold air of the air outlet 12, thereby improving the ice making speed of the ice making box 15 and further improving the ice making speed of the ice maker.

[0036] Of course, in other embodiments, the fixing manner of the ice making box, the ice storage box, and the cavity wall of the freezing chamber of the refrigerator is not limited, for example, a partition plate instead of a support can be used to place the ice storage box and the ice making box.

[0037] Optionally, the refrigerator of the embodiment further includes a refrigeration mechanism 22 for providing cold air to the freezing chamber.

[0038] Optionally, the refrigeration mechanism 22 of the embodiment comprises a compressor, a condenser, an evaporator, a throttling component, the compressor, the condenser, the throttling component, and the evaporator. The compressor is connected to the evaporator and the condenser through pipelines, and is a power source of the refrigerator, used to change the low-temperature and low-pressure dry saturated vapor from the evaporator into high-temperature and high-pressure superheated vapor through adiabatic compression, and then supply the superheated vapor to the condenser; the condenser is also connected to the throttling component, used to condense the high-temperature and high-pressure superheated vapor from the compressor under isobaric conditions, and then dissipate heat to the surrounding medium to become high-pressure subcooled liquid; the throttling component is also connected to the evaporator, and the high-pressure subcooled liquid changes into low-temperature and low-pressure refrigerant vapor after throttling by the throttling component, and then enters the evaporator to evaporate; the low-temperature and low-pressure refrigerant wet vapor after throttling by the throttling component boils in the evaporator under isobaric conditions, absorbs heat from the surrounding medium, and then changes into low-temperature and low-pressure dry saturated vapor to the compressor.

[0039] The controller is connected to the compressor to control the operation of the compressor. Specifically, when the ice-making temperature of the ice-making mechanism 20 is higher than the first preset temperature, the controller controls the rotation speed of the compressor to increase to the first rotation speed, so that the temperature of the cold air in the air duct is reduced, thereby reducing the air outlet temperature of the first air outlet 12 to the freezing chamber, and further reducing the temperature of the cold air flowing through the surface space of the ice-making mechanism 20, and improving the ice-making speed of the ice-making mechanism 20; wherein the first rotation speed can be set according to the fast ice-making time, ice-making amount and other parameters. When the ice-making temperature of the ice-making mechanism 20 is lower than or equal to the second preset temperature, it is determined that the ice-making is completed, and then the rotation speed of the compressor is controlled to decrease to the second rotation speed, which is less than the first rotation speed. Wherein the second rotation speed is the rotation speed of the refrigerator in the non-fast ice-making state and in the normal working state. After the ice-making is completed, the rotation speed of the compressor is adjusted back to the rotation speed in the non-fast ice-making state, which can save energy consumption and reduce the temperature fluctuation in the freezing chamber.

[0040] Optionally, the throttling component of the embodiment comprises an electronic expansion valve connected to the controller, and the controller controls the opening degree of the electronic expansion valve to adjust the air outlet temperature of the first air outlet 12.

[0041] Specifically, the controller controls the opening degree of the electronic expansion valve to increase to a first opening degree when the ice-making temperature of the ice-making mechanism is higher than a first preset temperature, so that the cold air temperature in the air duct is reduced, thereby being able to reduce the air outlet temperature of the first air outlet 12 to the freezing chamber, and further being able to reduce the temperature of the cold air flowing through the surface space of the ice-making mechanism 20, and being able to improve the ice-making speed of the ice-making mechanism 20; wherein the first opening degree can be set according to the fast ice-making time, ice-making amount and other parameters. When the ice-making temperature of the ice-making mechanism 20 is lower than or equal to a second preset temperature, the controller determines that the ice-making is completed, and then controls the opening degree of the electronic expansion valve to decrease to a second opening degree, which is smaller than the first opening degree. Wherein the second opening degree is the opening degree of the refrigerator in the non-fast ice-making state and in the normal working state. After the ice-making is completed, the controller adjusts the opening degree of the electronic expansion valve back to the opening degree in the non-fast ice-making state, which can save energy consumption and reduce the temperature fluctuation in the freezing chamber.

[0042] Optionally, the refrigerator of the embodiment further comprises a display and control module connected with the controller. The user can set whether to enter the fast ice-making function through the display and control module.

[0043] Optionally, the air duct mechanism comprises an air duct plate and a fan 21. The air duct plate has a first air outlet 12 and a second air outlet 13; the fan 21 is arranged in the air duct of the air duct plate and is arranged close to the first air outlet 12, for blowing the cold air in the air duct into the freezing chamber quickly to improve the refrigeration effect of the refrigerator.

[0044] The refrigeration mechanism 22 can provide a heat exchange medium for the ice-making mechanism 20 to ensure the ice-making effect of the ice-making mechanism. The air duct of the air duct mechanism can guide the cold air generated by the refrigeration mechanism 22 to the air outlet 12.

[0045] Optionally, the refrigerator of the embodiment further comprises a display and control module connected with the controller. The fast ice-making instruction is generated to the controller based on the user, i.e. the user demand.

[0046] Optionally, the gap between the projection of the ice-making mechanism 20 on the side wall and the first air outlet 12 is 0-5 cm. For example, the gap can be 0 cm, 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, etc.

[0047] The gap between the projection of the ice-making mechanism 20 on the side wall provided with the first air outlet 12 and the first air outlet 12 can be equivalent to the height difference between the ice-making mechanism 20 and the first air outlet 12. By setting the height difference to 0-5 cm, not only the cold air introduced by the first air outlet 12 can be reduced, but also the heat dissipation effect of the cold air introduced by the first air outlet 12 on the ice-making mechanism 20 can be improved, i.e. the refrigeration effect of the freezing chamber can be ensured, and the ice-making efficiency of the ice-making mechanism 20 can be improved significantly.

[0048] For example, the projection of the ice making mechanism 20 on the side wall provided with the first air outlet 12 can be located below the first air outlet 12, and the distance between the upper surface of the ice making box 15 and the lower edge of the first air outlet 12 is 0-5 cm.

[0049] Optionally, the distance between the upper surface of the ice making box 15 and the lower edge of the first air outlet 12 is in a positive relationship with the length of the ice making box 15. The greater the length of the ice making box 15, the greater the distance between the upper surface of the ice making box 15 and the lower edge of the first air outlet 12, which can solve the problem that the wind is affected by gravity and blows downward, resulting in a reduction in the wind area or a reduction in the wind speed at the rear end of the ice making box 15, and poor ice making effect.

[0050] In the formula, the length of the ice making box 15 is the dimension of the ice making box 15 along the axis of the first air outlet 12, and the ice making surface of the ice making box 15 extends along the length direction.

[0051] In other embodiments, a wind direction adjusting mechanism can also be arranged in the freezing chamber and arranged close to the air outlet and the ice making mechanism. The wind direction adjusting mechanism can be used to adjust the flow direction of the cold air, so that the cold air is guided to the ice making mechanism, thereby further improving the ice making speed of the ice making mechanism.

[0052] Specifically, the wind direction adjusting mechanism can be a baffle or the like. One end of the baffle is connected to the cavity wall of the freezing chamber, and the other end is a free end. The free end rotates relative to the cavity wall to adjust the included angle between the baffle and the axis of the air outlet, thereby adjusting the flow direction of the cold air.

[0053] In other embodiments, a wind direction adjusting mechanism can also be arranged in the freezing chamber and arranged on the air outlet. The wind direction adjusting mechanism can be used to adjust the flow direction of the cold air, so that the cold air is guided to different areas of the ice making mechanism, thereby further improving the ice making uniformity and the ice making speed of the ice making mechanism.

[0054] Specifically, the wind direction adjusting mechanism can be a baffle assembly such as a grid piece or a swing leaf piece. One end of the baffle assembly is connected to the side wall of the freezing chamber, and the other end is a free end. The free end rotates relative to the side wall of the freezing chamber to adjust the included angle between the air duct of the baffle assembly and the axis of the air outlet, thereby adjusting the flow direction of the cold air.

[0055] The application further provides a control method of the refrigerator, as shown in Figure 3 Figure 3 is a flow diagram of an embodiment of the control method of the refrigerator. The control method of the embodiment can be used in the refrigerator described above. The control method of the embodiment specifically includes the following steps:

[0056] Step S31: In response to a fast ice making instruction, the ice making temperature of the ice making mechanism is obtained.

[0057] ​The user can input a quick ice making instruction through the display and control module of the refrigerator, and the controller controls the temperature detection mechanism to obtain the ice making temperature of the ice making mechanism in response to the quick ice making instruction.

[0058] The ice making temperature can be an ice making temperature obtained by a single temperature sensor, or an ice making temperature obtained by multiple temperature sensors after fusion processing of different ice making regions.

[0059] Step S32: In response to the ice making temperature being higher than the first preset temperature, the air outlet parameter of the first air outlet is adjusted to make the ice making mechanism quickly make ice.

[0060] Optionally, the air outlet parameter can include an air outlet amount, and the controller can control the first air outlet to be opened and the second air outlet to be closed to increase the air outlet amount of the first air outlet.

[0061] When the ice making temperature of the ice making mechanism is higher than the first preset temperature, the controller controls the driving mechanism to drive the first air door to open the first air outlet, and controls the driving mechanism to drive the second air door to close the second air outlet, so that the cold air in the air duct is introduced into the freezer compartment from the first air outlet, thereby increasing the air outlet amount of the first air outlet to the freezer compartment, and further increasing the ice making speed of the ice making mechanism.

[0062] Optionally, the air outlet parameter can also include an air outlet temperature, and the controller can also control the rotation speed of the compressor in the refrigeration mechanism to increase to a first rotation speed to reduce the air outlet temperature of the first air outlet.

[0063] Specifically, when the ice making temperature of the ice making mechanism is higher than the first preset temperature, the controller controls the rotation speed of the compressor to increase to the first rotation speed, so that the temperature of the cold air in the air duct is reduced, thereby reducing the air outlet temperature of the first air outlet to the freezer compartment, further reducing the temperature of the cold air flowing through the surface space of the refrigeration mechanism, and increasing the ice making speed of the ice making mechanism; wherein the first rotation speed can be set according to the quick ice making time, ice making amount and other parameters.

[0064] Optionally, the air outlet parameter can also include an air outlet temperature, and the controller can also control the opening degree of the electronic expansion valve in the refrigeration mechanism to increase to a first opening degree to reduce the air outlet temperature of the first air outlet.

[0065] Specifically, when the ice making temperature of the ice making mechanism is higher than the first preset temperature, the controller controls the opening degree of the electronic expansion valve to increase to the first opening degree, so that the temperature of the cold air in the air duct is reduced, thereby reducing the air outlet temperature of the first air outlet to the freezer compartment, further reducing the temperature of the cold air flowing through the surface space of the refrigeration mechanism, and increasing the ice making speed of the ice making mechanism; wherein the first opening degree can be set according to the quick ice making time, ice making amount and other parameters.

[0066] In other embodiments, the above-mentioned air outlet, compressor and electronic expansion valve can be controlled in a combined manner to adjust the air outlet temperature of the first air outlet.

[0067] Step S33: in response to the ice-making temperature being lower than or equal to the second preset temperature, determining that ice making is completed; wherein the first preset temperature is greater than the second preset temperature.

[0068] Optionally, the second preset temperature ranges from -5℃ to -3℃, which can be -5℃, -4.5℃, -4℃, -3.5℃, -3℃, etc. The ice-making temperature in this range is used as the basis for determining that ice making is completed, which not only ensures that the ice cubes in the ice-making mechanism are completely frozen, i.e., improves the ice-making effect, but also improves the ice-making speed.

[0069] In an application scenario, the second preset temperature is -5℃, which can ensure that the ice cubes are completely frozen and the appearance of the ice cubes is guaranteed. At this time, the second air outlet is controlled to be opened, which can quickly achieve uniform cooling of the freezing chamber and reduce temperature fluctuations in the freezing chamber.

[0070] In an application scenario, the second preset temperature is -3℃, which can achieve ice cube freezing and meet the demand for fast ice making, and can save energy consumption.

[0071] The method of this embodiment further includes: in response to ice making being completed, controlling the first air outlet and the second air outlet to be opened. Specifically, when the ice-making temperature of the ice-making mechanism is lower than or equal to the second preset temperature, the controller determines that ice making is completed, then controls the driving mechanism to drive the first air outlet to be opened, and controls the driving mechanism to drive the second air outlet to be opened by driving the second air door, so that the cold air in the air duct is introduced into the freezing chamber from the first air outlet and the second air outlet, achieving uniform cooling of the freezing chamber.

[0072] The method of this embodiment further includes: in response to ice making being completed, controlling the speed of the compressor to be reduced to a second speed, the second speed being less than the first speed. Specifically, when the ice-making temperature of the ice-making mechanism is lower than or equal to the second preset temperature, the controller determines that ice making is completed, then controls the speed of the compressor to be reduced to a second speed, the second speed being less than the first speed. The second speed is the speed of the refrigerator in the non-fast ice-making state and in the normal working state. After ice making is completed, the controller adjusts the speed of the compressor back to the speed in the non-fast ice-making state, which can save energy consumption and reduce temperature fluctuations in the freezing chamber.

[0073] The method of the embodiment further includes: in response to ice making being completed, controlling the opening degree of the electronic expansion valve to decrease to a second opening degree, the second opening degree being smaller than the first opening degree. Specifically, the controller determines that ice making is completed when the ice making temperature of the ice making mechanism is lower than or equal to a second preset temperature, and then controls the opening degree of the electronic expansion valve to decrease to the second opening degree, the second opening degree being smaller than the first opening degree. The second opening degree is the opening degree of the electronic expansion valve when the refrigerator is in the non-fast ice making state and in normal operation. After ice making is completed, the controller adjusts the opening degree of the electronic expansion valve to the opening degree in the non-fast ice making state, thereby saving energy consumption and reducing the fluctuation of the temperature in the freezer.

[0074] The embodiment acquires the ice making temperature of the ice making mechanism after receiving the fast ice making instruction, adjusts the air outlet parameter of the first air outlet arranged close to the ice making mechanism when the ice making temperature is higher than a first preset temperature, and adjusts the ice making speed of the ice making mechanism arranged close to the first air outlet, thereby realizing fast ice making of the refrigerator. The embodiment determines that ice making is completed when the ice making temperature is lower than or equal to a second preset temperature, thereby improving the control accuracy of fast ice making of the refrigerator, saving energy consumption, and reducing the fluctuation of the temperature in the freezer.
