The size of an air opening formed by the poke piece assembly 15 and the side wall of the first air channel 14 is adjusted by controlling the opening angle of the poke piece assembly 15, and the temperature of different gears of the refrigerating chamber 13 is controlled by controlling the work of the compressor 11 and the fan 12, so that the synchronous adjustment of the set gear of the refrigerating chamber 13 and the size of an air inlet can be realized.

The refrigerator 1 further includes a refrigeration sensor 132, the refrigeration sensor 132 is disposed in the refrigerating chamber 13, the refrigeration sensor 132 collects a first temperature in the refrigerating chamber 13, and the refrigeration sensor 132 is connected to the controller 18, so that the controller 18 determines whether the refrigerating chamber 13 has a refrigeration requirement or not and determines a set gear of the refrigerating chamber 13 according to the first temperature.

Referring to fig. 5, fig. 5 is a schematic view illustrating a third structure of a dial assembly in the refrigerator shown in fig. 1. The controller 18 is further configured to: when the set gear is a third gear, the compressor 11 and the fan 12 are controlled to work, the poke sheet assembly 15 is controlled to be opened to a third angle so as to form a third air opening 146 with the side wall of the first air duct 14 and keep the third angle for a third time, and the fan 12 sends cold air generated by the compressor 11 to the refrigerating chamber 13 through the third air opening 146; the third angle is greater than the second angle, and the third time is less than the second time. It is understood that the refrigerated compartment 13 may include a plurality of set gear positions, such as a first gear position corresponding to a first set temperature, a second gear position corresponding to a second set temperature, and a third gear position corresponding to a third set temperature. It should be noted that the first gear may be a strong gear, the second gear may be a medium gear, and the third gear may be a weak gear, the first set temperature is less than the second set temperature, and the second set temperature is less than the third set temperature.

When it is determined that there is a cooling demand for the refrigerating compartment 13, it is necessary to further determine the set gear position of the refrigerating compartment 13. Determining the set gear of the refrigerating compartment 13 can be considered from two aspects.

On the first hand, when the difference value between the first temperature and the first set temperature is greater than the first difference threshold value, the set gear of the refrigerating chamber 13 is determined to be the first gear; and when the difference value between the first temperature and the second set temperature is greater than a second difference threshold value, determining the set gear of the refrigerating chamber 13 as a second gear. Accordingly, when the difference between the first temperature and the third set temperature is greater than the third difference threshold, the set gear of the refrigerating compartment 13 is determined to be the third gear.

In a second aspect, the refrigerator 1 further includes a display control panel 19, and the display control panel 19 may include a display panel 192 and a plurality of control buttons 194. The display control board 19 may be electrically connected to the controller 18. The display panel 192 is used to display the first temperature of the refrigerator compartment 13, and various control buttons 194 may be used to determine the set gear position of the refrigerator compartment 13.

After the set gear of the refrigerating compartment 13 is determined, various operations may be performed by the controller 18.

In the first case, for example, when it is determined that the set gear of the refrigerating compartment 13 is the first gear, the compressor 11 and the fan 12 are controlled to operate, and the dial assembly 15 is controlled to be opened to the first angle to form the first air opening 142 with the side wall of the first air duct 14 and to be maintained for the first time, the fan 12 sends the cold air generated by the compressor 11 to the refrigerating compartment 13 through the first air opening 142.

In the second case, when the set gear of the refrigerating chamber 13 is determined to be the second gear, the compressor 11 and the fan 12 are controlled to work, and the poke piece assembly 15 is controlled to be opened to the second angle to form the second air opening 144 with the side wall of the first air duct 14 and keep the second time; the fan 12 sends the cold air generated by the compressor 11 to the refrigerating chamber 13 through the second air opening 144; the first angle is less than the second angle and the first time is greater than the second time.

In the third case, please continue to refer to FIG. 5. When the set gear of the refrigerating chamber 13 is a third gear, the compressor 11 and the fan 12 are controlled to work, the dial plate assembly 15 is controlled to be opened to a third angle to form a third air opening 146 with the side wall of the first air duct 14 and keep for a third time, and the fan 12 sends cold air generated by the compressor 11 to the refrigerating chamber 13 through the third air opening 146; the second angle is less than the third angle, and the second time is greater than the third time.

Further, when it is determined that there is no cooling demand in the refrigerating chamber 13, the compressor 11 and the fan 12 are controlled to be stopped, and the paddle assembly 15 is controlled to be closed. Referring to fig. 6, the state of the dial assembly 15 at this time can be seen, and fig. 6 is a fourth structural schematic diagram of the dial assembly in the refrigerator shown in fig. 1.

Illustratively, with continued reference to fig. 3-5, paddle assembly 15 includes a motor 152, a linkage 154, and a paddle 156. The connecting rod 154 is connected with the motor 152, and the shifting piece 156 is fixedly connected with the connecting rod 154. The motor 152 controls the rotation of the poking piece 156 through the connecting rod 154 to adjust the size of the air opening formed by the poking piece assembly 15 and the side wall of the first air duct 14, so as to adjust the temperature corresponding to different set gears of the refrigerating chamber 13. When the poking piece 156 is opened to the first angle, the poking piece assembly 15 and the side wall of the first air duct 14 form the first air opening 142, and the air passes through the first air opening 142 and keeps the first time, so that the air volume entering the refrigerating chamber 13 in the first time can make the temperature of the refrigerating chamber 13 reach the first set temperature. When the poking piece 156 is opened to the second angle, the poking piece assembly 15 and the side wall of the first air duct 14 form the second air opening 144, and the air passes through the second air opening 144 and is kept for the second time, so that the air volume entering the refrigerating chamber 13 in the second time can make the temperature of the refrigerating chamber 13 reach the second set temperature. When the poking piece 156 is opened to a third angle, at this time, the poking piece assembly 15 and the side wall of the first air duct 14 form a third air opening 146, and the air passes through the third air opening 146 and is kept for a third time, so that the air volume entering the refrigerating chamber 13 in the third time can make the temperature of the refrigerating chamber 13 reach a third set temperature. Illustratively, the first angle may be 30 °, the second angle may be 60 °, and the third angle may be 90 °.

In addition, the refrigerator 1 may further include a freezing chamber 16 and a second duct 17, the second duct 17 communicating with the freezing chamber. The first air duct 14 and the second air duct 17 may be connected to an air inlet, that is, the air inlet is divided into two branches, and the air sent by the fan 12 passes through the air inlet and then is respectively sent to the refrigerating chamber 13 through the first air duct 14 and sent to the freezing chamber 16 through the second air duct 17. The cross-sectional areas of the first air duct 14 and the second air duct 17 may be equal, and of course, the cross-sectional areas of the first air duct 14 and the second air duct 17 may also be unequal, and are not limited herein. A frost sensor 162 may also be disposed within the freezer compartment 16, and the frost sensor 162 may sense a second temperature within the freezer compartment 16 and determine whether there is a need for cooling the freezer compartment 16 based on the second temperature. When there is a refrigerating demand in the freezing chamber 16, the operation of the compressor 11 and the fan 12 is controlled so that the cool air generated by the compressor 11 is supplied to the freezing chamber 16 by the fan 12. In addition, when refrigerating room 13 is in a different setting range, freezing room 16 defaults to the same range as refrigerating room 13, and therefore, the controller 18 may control the different setting range of refrigerating room 13. For example, when the refrigerating compartment 13 is in the first gear position and the refrigerating compartment 13 is in the strong gear position, the freezing compartment 16 defaults to the strong gear position, the controller 18 controls the compressor 11 and the fan 12 to operate, controls the paddle assembly 15 to open to the first angle to form the first air opening 142 with the side wall of the first air duct 14 and keeps the first angle for the first time, and the fan 12 sends the cold air generated by the compressor 11 to the refrigerating compartment 13 through the first air opening 142.

In order to more clearly describe the control method of the embodiment of the present application for different set gears of the refrigerating chamber, the following description will be made from the perspective of the control method of the refrigerator.

Exemplarily, please refer to fig. 7, and fig. 7 is a first flowchart of a control method of a refrigerator according to an embodiment of the present application. The structure of the refrigerator 1 can be described with reference to fig. 1 to 6 and the above description, and will not be described again. The control method of the refrigerator comprises the following steps:

101. it is detected whether a refrigeration demand of the refrigerating compartment is received.

A first temperature of the refrigerated compartment 13 is obtained, and a determination is made as to whether there is a refrigeration demand on the refrigerated compartment 13 based on the first temperature. Illustratively, if the temperature of the refrigeration compartment 13 needs to be controlled, a first temperature of the refrigeration compartment 13 needs to be obtained first. The first temperature of the refrigerating compartment 13 may be sensed by a refrigerating sensor 132 provided at the refrigerating compartment 13. The refrigeration sensor 132 may employ a temperature sensor.

After the first temperature of the refrigerating chamber 13 is obtained, whether the refrigerating chamber 13 has a refrigerating requirement can be judged according to the first temperature. For example, when the first temperature is greater than the first threshold value, it may be determined that the refrigerating compartment 13 has a cooling demand.

102. When a refrigerating demand of the refrigerating chamber is received, a set gear of the refrigerating chamber is obtained.

For example, the refrigerating compartment 13 may include a plurality of set gears, such as a first gear corresponding to a first set temperature, a second gear corresponding to a second set temperature, and a third gear corresponding to a third set temperature. It should be noted that the first gear may be a strong gear, the second gear may be a medium gear, and the third gear may be a weak gear, the first set temperature is less than the second set temperature, and the second set temperature is less than the third set temperature.

Obtaining the set gear of the refrigerating compartment 13 can be considered from two aspects. On the first hand, when the difference value between the first temperature and the first set temperature is greater than the first difference threshold value, the set gear of the refrigerating chamber 13 is determined to be the first gear; and when the difference value between the first temperature and the second set temperature is greater than a second difference threshold value, determining the set gear of the refrigerating chamber 13 as a second gear. Accordingly, when the difference between the first temperature and the third set temperature is greater than the third difference threshold, the set gear of the refrigerating compartment 13 is determined to be the third gear.

In a second aspect, the set gear of the refrigerating compartment 13 may be determined by acquiring a first control command, a second control command, and a third control command for externally controlling the refrigerating compartment 13. For example, the first control command may correspond to a first gear, the second control command may correspond to a second gear, and the third control command may correspond to a third gear, and the user may operate a control button on the refrigerator 1, such as the refrigerator 1, to send the control command to control the set gear of the refrigerating chamber 13.

103. When the set gear is the first gear, the compressor and the fan are controlled to work, and the poking piece assembly is controlled to be opened to the first angle to form a first air opening with the side wall of the first air channel and keep the first angle for the first time, so that the fan sends cold air generated by the compressor to the refrigerating chamber through the first air opening.

104. When the set gear is a second gear, the compressor and the fan are controlled to work, and the poking piece assembly is controlled to be opened to a second angle so as to form a second air port with the side wall of the first air channel and keep the second air port for a second time; the fan sends cold air generated by the compressor to the refrigerating chamber through the second air port; the size of the second tuyere is larger than that of the first tuyere, and the second time is smaller than the first time.

With respect to steps 103 and 104:

when the refrigerating chamber 13 is determined as the first gear, the first air opening 142 is formed by the dial component 15 and the side wall of the first air duct 14, and the air passes through the first air opening 142 and is kept for the first time, so that the air volume entering the refrigerating chamber 13 in the first time can enable the temperature of the refrigerating chamber 13 to reach the first set temperature. When the set gear of the refrigerating chamber 13 is the second gear, the second air opening 144 is formed by the dial component 15 and the side wall of the first air duct 14, and the air passes through the second air opening 144 and is kept for the second time, so that the air volume entering the refrigerating chamber 13 in the second time can enable the temperature of the refrigerating chamber 13 to reach the second set temperature. Illustratively, the first angle may be 30 ° and the second angle may be 60 °. The set gear and the size of the air opening of the refrigerating chamber 13 can be synchronously adjusted by controlling the size of the air opening formed by the poking piece assembly 15 and the side wall of the first air duct 14.

It should be noted that the control method of the refrigerator provided in the embodiments of the present application is not limited to the above steps. Exemplarily, please refer to fig. 8, and fig. 8 is a second flowchart of the control method for the refrigerator according to the embodiment of the present application. The control method of the refrigerator comprises the following steps:

201. it is detected whether a refrigeration demand of the refrigerating compartment is received.

202. When a refrigerating demand of the refrigerating chamber is received, a set gear of the refrigerating chamber is obtained.

203. When the set gear is the first gear, the compressor and the fan are controlled to work, and the poking piece assembly is controlled to be opened to the first angle to form a first air opening with the side wall of the first air channel and keep the first angle for the first time, so that the fan sends cold air generated by the compressor to the refrigerating chamber through the first air opening.

steps

204. The temperature of the refrigerating chamber is controlled to reach the first set temperature.

205. When the set gear is a second gear, the compressor and the fan are controlled to work, and the poking piece assembly is controlled to be opened to a second angle so as to form a second air port with the side wall of the first air channel and keep the second air port for a second time; the fan sends cold air generated by the compressor to the refrigerating chamber through the second air port; the size of the second tuyere is larger than that of the first tuyere, and the second time is smaller than the first time.

Step 205 may refer to the description of step 104, which is not described herein.

206. And controlling the temperature of the refrigerating chamber to reach a second set temperature, wherein the first set temperature is less than the second set temperature.

The setting temperatures corresponding to different gears are different, for example, a first setting temperature of the first gear may be set to a second setting temperature that is lower than the second gear. The first gear may correspond to a strong gear and the second gear may correspond to a medium gear. When the refrigerating chamber 13 is determined to be in the second gear, the compressor 11 and the fan 12 are controlled to work, the poke sheet assembly 15 is controlled to be opened to a second angle to form a second air opening 144 with the side wall of the first air duct 14, and air passes through the second air opening 144 and is kept for a second time, so that the air volume entering the refrigerating chamber 13 in the second time can enable the temperature of the refrigerating chamber 13 to reach a second set temperature.

207. When the set gear is a third gear, the compressor and the fan are controlled to work, the poking piece assembly is controlled to be opened to a third angle so as to form a third air port with the side wall of the first air channel and keep the third time, and the fan sends cold air generated by the compressor to the refrigerating chamber through the third air port; the second angle is less than the third angle, and the second time is greater than the third time.

When the refrigerating chamber 13 is determined to be in the third gear, the compressor 11 and the fan 12 are controlled to work, the poke sheet assembly 15 is controlled to be opened to a third angle to form a third air opening 146 with the side wall of the first air duct 14, and air passes through the third air opening 146 and is kept for a third time, so that the air volume entering the refrigerating chamber 13 in the third time can enable the temperature of the refrigerating chamber 13 to reach a third set temperature. The third tuyere 146 is larger than the second tuyere 144 and the third time is smaller than the second time, for example, the third angle may be 90 °. The set gear and the size of the air opening of the refrigerating chamber 13 can be synchronously adjusted by controlling the size of the air opening formed by the poking piece assembly 15 and the side wall of the first air duct 14.
