[0043] Combination Figure 1-5 As shown, in some embodiments, the refrigerator includes: an air supply component 400 and an air outlet nozzle 500. The air supply component 400 is arranged on the side wall of the refrigerator body 200 or the door body 300; the air outlet nozzle 500 is arranged on one side of the air supply component 400, and the air inlet end of the air outlet nozzle 500 is connected with the air outlet end of the air supply component 400; wherein, the air outlet end of the air outlet nozzle 500 can extend into the bag opening of the fresh-keeping bag 600 to blow air into the fresh-keeping bag 600, so that the fresh-keeping bag 600 is stretched open.

[0044] The refrigerator provided by the embodiment of the present disclosure is provided with an air supply component 400, and the air supply component 400 is used to supply air to the air outlet 500. When the fresh-keeping bag 600 needs to be opened, the air outlet 500 is extended into the bag opening of the fresh-keeping bag 600, and air is blown into the fresh-keeping bag 600 through the air outlet 500, so that the fresh-keeping bag 600 is opened, so that the user can put food into the fresh-keeping bag 600 for packaging and storage. The form of opening the fresh-keeping bag 600 by blowing air through the air outlet 500 reduces the difficulty of opening the fresh-keeping bag 600, improves the efficiency of food storage, and meets the diverse needs of users.

[0045] Optionally, the side wall of the box body 200 or the door body 300 is provided with a mounting groove 700, and the air supply assembly 400 is embedded in the mounting groove 700. In this way, the air supply assembly 400 is embedded in the mounting groove 700, and the air supply assembly 400 is hidden to prevent the air supply assembly 400 from protruding from the side wall of the box body 200 or the door body 300.

[0046] Optionally, the air outlet nozzle 500 is movably arranged on one side of the air supply component 400, and the air outlet nozzle 500 can be moved to hide in the mounting groove 700, or extend along the notch of the mounting groove 700 to blow air into the fresh-keeping bag 600. In this way, the air outlet nozzle 500 can be moved relative to the air supply component 400, which is convenient for users to use. When the air outlet nozzle 500 is not needed, the air outlet nozzle 500 is moved to hide in the mounting groove 700. When the air outlet nozzle 500 is needed to blow air to open the fresh-keeping bag 600, the user takes the air outlet nozzle 500 out of the mounting groove 700.

[0047] Optionally, the air inlet end of the air outlet nozzle 500 is connected to the air outlet end of the air supply assembly 400 through a corrugated hose. In this way, the air outlet nozzle 500 is connected to the air supply assembly 400 through the corrugated hose, so that the air outlet nozzle 500 can be movably taken and placed, and the airflow in the air supply assembly 400 can be smoothly flowed into the air outlet nozzle 500.

[0048] Optionally, a sealing cover is provided at the notch of the installation slot 700, and the sealing cover is used to open or close the notch of the installation slot 700. In this way, when the air outlet nozzle 500 is not needed, the air outlet nozzle 500 is placed in the installation slot 700, and then the notch of the installation slot 700 is sealed by the sealing cover. When the air outlet nozzle 500 needs to be used, the sealing cover is opened and the air outlet nozzle 500 is taken out of the installation slot 700.

[0049] Combination Figure 1 As shown, in one embodiment, the air supply component 400 includes: a fan 410. The fan 410 is embedded in the side wall of the box body 200 or the door body 300, and the air outlet end of the fan 410 is connected to the air inlet end of the air outlet nozzle 500. In this way, by setting the fan 410 to supply air to the air outlet nozzle 500, when it is necessary to blow air to the bag opening of the fresh-keeping bag 600 through the air outlet nozzle 500 to open the fresh-keeping bag 600, the fan 410 is started to supply air to the air outlet nozzle 500. The air supply stability of the fan 410 is high, and it can continuously supply air to the air outlet nozzle 500, and the size of the air output can be adjusted according to demand to better meet the diverse needs of users.

[0050] Optionally, the side wall of the door body 300 is provided with a mounting groove 700, and the fan 410 is embedded in the mounting groove 700. In this way, the fan 410 is embedded in the mounting groove 700 of the side wall of the door body 300, and the user can operate the air outlet 500 to blow air to open the fresh-keeping bag 600 when standing in the area facing the door body 300, which is convenient for the user's operation.

[0051] Optionally, the air inlet end of the fan 410 is connected to the refrigerator compartment 210 or the freezer compartment 220 of the refrigerator. In this way, the cold air flow in the refrigerator compartment 210 or the freezer compartment 220 of the refrigerator is drawn by the fan 410 and supplied to the air outlet 500, and then the cold air flow is blown out by the air outlet 500 to open the fresh-keeping bag 600. The blown cold air flow can pre-cool the fresh-keeping bag 600 while opening the fresh-keeping bag 600, so that the temperature inside the fresh-keeping bag 600 is reduced, and then the food is put into the fresh-keeping bag 600 for packaging, thereby further improving the fresh-keeping effect of the food.

[0052] Specifically, the air inlet end of the fan 410 is connected to the refrigerating chamber 210. In this way, the temperature inside the refrigerating chamber 210 is higher than the temperature inside the freezing chamber 220. To prevent the air flow from being blown out of the air outlet 500 from being too low in temperature, the air inlet end of the fan 410 is connected to the refrigerating chamber 210, and the cold air flow in the refrigerating chamber 210 is introduced by the fan 410 and blown out from the air outlet 500 to open the fresh-keeping bag 600.

[0053] Optionally, an air inlet channel is provided on one side of the mounting groove 700 at a position corresponding to the air inlet end of the fan 410, one end of the air inlet channel is connected to the air inlet end of the fan 410, and the other end is connected to the refrigerating chamber 210. In this way, the fan 410 generates negative pressure at its air inlet end during operation, and the cold air in the refrigerating chamber 210 flows out through the air inlet channel under the action of the negative pressure.

[0054] Combination Figure 2 and Figure 3 As shown, in another embodiment, the air supply component 400 includes: an air pump 420 and an oxygen absorption pipe 430. The exhaust end of the air pump 420 is connected to the air inlet end of the air outlet nozzle 500; one end of the oxygen absorption pipe 430 is connected to the air intake end of the air pump 420, and the other end is connected to the refrigerator compartment 210 of the refrigerator; wherein, a first oxygen permeable membrane 431 is arranged inside the oxygen absorption pipe 430. In this way, the air pump 420 is arranged to provide the air outlet airflow for the air outlet nozzle 500, and the air pump 420 is connected to the refrigerator compartment 210 through the oxygen absorption pipe 430. Since the first oxygen permeable membrane 431 is arranged inside the oxygen absorption pipe 430, the airflow sucked out by the air pump 420 is oxygen, and the oxygen in the refrigerator compartment 210 is absorbed by the cooperation of the air pump 420 and the oxygen absorption pipe 430, and the oxygen content in the refrigerator compartment 210 is reduced, thereby extending the preservation effect of the food stored in the refrigerator compartment 210. The oxygen in the refrigerating chamber 210 is sucked out by the suction pump 420 and supplied to the air outlet 500. The air outlet 500 blows the sucked oxygen toward the fresh-keeping bag 600 to open the fresh-keeping bag 600, thereby improving the opening efficiency of the fresh-keeping bag 600 and the fresh-keeping effect in the refrigerating chamber 210.

[0055] Optionally, a mounting groove 700 is provided on the side wall of the box body 200, and the air pump 420 is embedded in the mounting groove 700. One end of the oxygen absorption tube 430 extends into the mounting groove 700 and communicates with the air suction end of the air pump 420, and the other end extends into the refrigerating chamber 210. In this way,

[0056] Optionally, an oxygen-controlled storage drawer 211 is provided inside the refrigerator 210, and the other end of the oxygen absorption tube 430 is connected to the oxygen-controlled storage drawer 211. In this way, by providing the oxygen-controlled storage drawer 211, an oxygen-controlled fresh-keeping area is formed inside the refrigerator 210, and the oxygen in the oxygen-controlled storage drawer 211 is absorbed by the oxygen absorption tube 430, so that the food stored in the oxygen-controlled storage drawer 211 can be kept fresh for a longer time.

[0057] Optionally, a tube hole is formed on the side wall of the oxygen-controlled storage drawer 211 , and the other end of the oxygen absorption tube 430 extends into the tube hole and communicates with the oxygen-controlled storage drawer 211 .

[0058] Optionally, the air supply component 400 also includes: an air tank 440. The air tank 440 is connected between the exhaust end of the air pump 420 and the air inlet end of the air outlet nozzle 500, and a one-way valve 441 is set at the position where the air tank 440 is connected to the exhaust end of the air pump 420, so that the air discharged from the exhaust end of the air pump 420 can only flow into the air tank 440 in one direction. In this way, since the oxygen-controlled storage drawer 211 needs to extract oxygen for oxygen control and preservation when the food is placed, it is impossible to adapt to the air supply demand of the air outlet nozzle 500 at any time. Therefore, the air tank 440 is set to store the extracted oxygen, and when the air outlet nozzle 500 needs to blow out air flow to open the fresh-keeping bag 600, the high-pressure oxygen in the air tank 440 can be blown out through the air outlet nozzle 500. The setting of the air tank 440 ensures the air supply of the air outlet nozzle 500 and improves the stability of the fresh-keeping bag 600. Furthermore, due to the provision of the one-way valve 441 , the oxygen discharged from the air pump 420 can only enter the gas storage tank 440 in one direction, thereby improving the stability of the gas pressure in the gas storage tank 440 .

[0059] Optionally, the gas storage tank 440 is connected to the air inlet end of the air outlet nozzle 500 through a connecting pipe, and the connecting pipe is connected to a solenoid valve 442. In this way, the opening and closing of the connecting pipe is controlled by the solenoid valve 442, thereby controlling the timing of the high-pressure oxygen stored in the gas storage tank 440 flowing into the air outlet nozzle 500. When it is necessary to blow air through the air outlet nozzle 500 to the fresh-keeping bag 600, the solenoid valve 442 is controlled to open, and the high-pressure oxygen in the gas storage tank 440 flows into the air outlet nozzle 500 and is blown out. When it is not necessary to blow air through the air outlet nozzle 500, the solenoid valve 442 is controlled to close, and the connecting pipe is closed at this time.

[0060] Combination Figure 4As shown, in one embodiment, the refrigerator further includes: an exhaust component 800. The exhaust component 800 is disposed on the side wall of the housing 200 or the door 300, and is used to extract the air in the fresh-keeping bag 600 after the food is packaged. In this way, after the food is packaged in the fresh-keeping bag 600, since the interior of the fresh-keeping bag 600 is filled with gas, the fresh-keeping bag 600 cannot be closely attached to the surface of the food, and the fresh-keeping effect of the food is still poor. Therefore, the exhaust component 800 is provided to extract the air in the fresh-keeping bag 600 after the food is packaged, reduce the oxygen content in the fresh-keeping bag 600, and form a state close to vacuum inside the fresh-keeping bag 600, thereby further improving the fresh-keeping effect of the food.

[0061] Optionally, when the air supply assembly 400 is disposed on the side wall of the door body 300, the air extraction assembly 800 is disposed on the side wall of the door body 300; when the air supply assembly 400 is disposed on the side wall of the box body 200, the air extraction assembly 800 is disposed on the side wall of the box body 200. In this way, the air extraction assembly 800 and the air supply assembly 400 are disposed together on the side wall of the door body 300 or the side wall of the box body 200. After the fresh-keeping bag 600 is opened by the air outlet nozzle 500, the air extraction assembly 800 can be efficiently operated to absorb the air in the fresh-keeping bag 600, and the user does not need to move the position, thereby improving the user experience.

[0062] Optionally, the air extraction component 800 includes: an air extraction pump 810 and an air extraction pipe 820. One end of the air extraction pipe 820 is connected to the air extraction end of the air extraction pump 810, and the other end can be extended into the fresh-keeping bag 600 after the food is packaged; wherein, a second oxygen permeable membrane is arranged in the air extraction pipe 820. In this way, the air extraction negative pressure is provided by the air extraction pump 810, and the end of the air extraction pipe 820 is extended into the fresh-keeping bag 600 to absorb the air in the fresh-keeping bag 600. In the process of air extraction, it is inevitable that there will be a small amount of air in the fresh-keeping bag 600 for buffering. Therefore, a second oxygen permeable membrane is arranged in the air extraction pipe 820, so that the air extracted by the air extraction pump 810 is all oxygen, and most of the buffer air retained in the fresh-keeping bag 600 is nitrogen or carbon dioxide, which further reduces the oxygen content in the fresh-keeping bag 600 and improves the fresh-keeping effect of the food in the fresh-keeping bag 600.

[0063] Optionally, the exhaust end of the air pump 810 is communicated with the external environment, so that the extracted air can be discharged into the external environment.

[0064] Optionally, when the air extraction component 800 is disposed on the side wall of the box body 200, an embedded groove is disposed on the side wall of the box body 200, the air extraction pump 810 is disposed in the embedded groove, and the air extraction pipe 820 is an elastic hose. In this way, when the air extraction component 800 is not needed, the air extraction component 800 can be hidden in the embedded groove.

[0065] Exemplarily, when the air supply component 400 includes an air suction pump 420 and an oxygen absorption tube 430, the absorbed oxygen is blown out through the air outlet nozzle 500 to expand the fresh-keeping bag 600. At this time, most of the air in the fresh-keeping bag 600 is oxygen, and there is a very small amount of other gases. When the air in the fresh-keeping bag 600 is absorbed by the vacuum component 800, since a second oxygen-permeable membrane is provided in the vacuum tube 820, the oxygen in the fresh-keeping bag 600 can be efficiently extracted, so that the fresh-keeping bag 600 is more closely attached to the surface of the food, and a very small amount of other gases remain in the fresh-keeping bag 600, thereby further improving the preservation effect of the food in the fresh-keeping bag 600.

[0066] Combination Figure 5 As shown, in some embodiments, the refrigerator further includes: a storage box 900. The storage box 900 is arranged on the side wall of the door body 300, and is used to place the fresh-keeping bag 600. In this way, the storage box 900 is arranged on the side wall of the door body 300 to place the fresh-keeping bag 600, so that the user can tear off the fresh-keeping bag 600 at any time to pack the food.

[0067] Optionally, a side wall of the storage box 900 is provided with a take-in and take-out opening 910, and a cutting blade 920 is provided in the take-in and take-out opening 910, and the fresh-keeping bag 600 is drawn out of the storage box 900 along the take-in and take-out opening 910. In this way, when the user needs to tear off the fresh-keeping bag 600, he pulls one end of the fresh-keeping bag 600, so that the fresh-keeping bag 600 extending out of the drawing gap moves toward the blade of the cutting blade 920, and the fresh-keeping bag 600 at the drawing gap is cut and broken by the blade, thereby completing the tearing of the fresh-keeping bag 600. When tearing off the fresh-keeping bag 600, the user does not need to cooperate with both hands to operate, and can complete the tearing of the fresh-keeping bag 600 with one hand, thereby improving the tearing efficiency of the fresh-keeping bag 600 and improving the user experience.

[0068] Optionally, the refrigerator further includes: an acquisition module. The acquisition module is disposed on the side wall of the cabinet 200 or the door 300, and is used to acquire identification information of the fresh-keeping bag 600 and / or identification information of the food. In this way, the identification information of the fresh-keeping bag 600 and / or the food is acquired through the acquisition module, so that the refrigerator controls the air supply component 400 and the exhaust component 800 according to the identification information of the fresh-keeping bag 600 and / or the food.

[0069] Optionally, the acquisition module is a camera.

[0074] An embodiment of the present disclosure provides a refrigerator, comprising the above-mentioned control device for a refrigerator.

[0075] Combination Figure 7 As shown, in some embodiments, a control method for a refrigerator includes:

[0076] S01, the processor obtains identification information of the fresh-keeping bag;

[0077] S02, the processor controls the air volume of the air outlet according to the identification information of the fresh-keeping bag.

[0078] According to the control method for a refrigerator provided by the embodiment of the present disclosure, since there are differences in the types and sizes of fresh-keeping bags, different fresh-keeping bags also require different amounts of airflow when they are opened. Therefore, the processor controls the air outlet of the air outlet according to the obtained identification information of the fresh-keeping bag, so that the air outlet of the air outlet is better adapted to the opening of the fresh-keeping bag, thereby reducing energy consumption while ensuring the opening efficiency of the fresh-keeping bag.

[0079] Optionally, the processor obtains the identification information of the fresh-keeping bag, including: the processor obtains the identification information of the fresh-keeping bag sent by the camera. In this way, the identification information of the fresh-keeping bag is collected by the camera, which simplifies the acquisition process of the identification information of the fresh-keeping bag and improves the acquisition accuracy.

[0080] Optionally, the processor controls the air volume of the air outlet according to the identification information of the fresh-keeping bag, including: the processor controls the operating state of the air supply component according to the identification information of the fresh-keeping bag, thereby controlling the air volume of the air outlet. In this way, since the air flow of the air outlet is provided by the air supply component, the air volume of the air outlet can be accurately controlled by controlling the operating state of the air supply component.

[0081] Optionally, the identification information of the fresh-keeping bag includes: the range of the volume of the fresh-keeping bag. In this way, fresh-keeping bags of different volumes require different airflows when they are opened, and the volumes of fresh-keeping bags vary, so the processor controls the air volume of the air outlet according to the range of the volume of the fresh-keeping bag, so that the air volume of the air outlet is adapted to the volume of the fresh-keeping bag.

[0082] In one embodiment, when the air supply component is a fan, the processor controls the operating state of the air supply component according to the identification information of the fresh-keeping bag, including: the processor controls the operating time of the fan and / or the rotation speed of the fan according to the identification information of the fresh-keeping bag. In this way, the operating time of the fan and / or the rotation speed of the fan can affect the air volume of the air outlet, so the processor controls the operating time of the fan and / or the rotation speed of the fan according to the identification information of the fresh-keeping bag, so that the air volume of the air outlet is adapted to the air volume required for the fresh-keeping bag to be opened.

[0083] Specifically, the processor controls the running time of the fan according to the identification information of the fresh-keeping bag.

[0084] Exemplarily, the volume range of the fresh-keeping bag is divided into: a first range, a second range and a third range, wherein the maximum value in the first range is less than the minimum value in the second range, and the maximum value in the second range is less than the minimum value in the third range. The fan operation time corresponding to the first range is 3 seconds, the fan operation time corresponding to the second range is 6 seconds, and the fan operation time corresponding to the third range is 8 seconds. When the processor determines that the identification information of the fresh-keeping bag is within the first range, the fan is controlled to operate for 3 seconds. When the processor determines that the identification information of the fresh-keeping bag is within the second range, the fan is controlled to operate for 6 seconds. When the processor determines that the identification information of the fresh-keeping bag is within the third range, the fan is controlled to operate for 8 seconds.

[0085] It can be understood that the camera has a computing unit inside, and the camera collects the volume of the fresh-keeping bag and calculates the range of the volume of the fresh-keeping bag.

[0086] In another embodiment, when the air supply component is an air suction pump, an oxygen absorption tube and an air storage tank, the processor controls the operation state of the air supply component according to the identification information of the fresh-keeping bag, including: the processor controls the opening time of the electromagnetic valve connected between the air storage tank and the air outlet nozzle according to the identification information of the fresh-keeping bag. In this way, when the air supply component is an air suction pump, an oxygen absorption tube and an air storage tank, the oxygen in the refrigerated room is sucked into the air storage tank by the air suction pump for storage, and then the air supply of the air outlet nozzle is controlled by the on-off of the electromagnetic valve connected between the air storage tank and the air outlet nozzle. Therefore, the processor controls the opening time of the electromagnetic valve according to the identification information of the fresh-keeping bag, so that the air volume of the air outlet nozzle is adapted to the air volume required for the fresh-keeping bag to be opened.

[0087] Exemplarily, the first range corresponds to a solenoid valve opening time of 2 seconds, the second range corresponds to a solenoid valve opening time of 4 seconds, and the third range corresponds to a solenoid valve opening time of 7 seconds. When the processor determines that the identification information of the fresh-keeping bag is in the first range, the solenoid valve is controlled to be closed after 2 seconds of opening; when the processor determines that the identification information of the fresh-keeping bag is in the second range, the solenoid valve is controlled to be closed after 4 seconds of opening; when the processor determines that the identification information of the fresh-keeping bag is in the third range, the solenoid valve is controlled to be closed after 7 seconds of opening.

[0088] Combination Figure 8 As shown, in some other implementations, a control method for a refrigerator includes:

[0089] S01, the processor obtains identification information of the fresh-keeping bag;

[0090] S02, the processor controls the air volume of the air outlet according to the identification information of the fresh-keeping bag;

[0091] S03, the processor obtains identification information of the food to be packaged;

[0092] S04, the processor controls the air extraction amount of the air extraction component according to the identification information of the food to be packaged and the identification information of the fresh-keeping bag.

[0093] According to the control method for refrigerators provided by the embodiment of the present disclosure, after the food is packaged in a fresh-keeping bag, the air in the fresh-keeping bag needs to be extracted by the air extraction component to improve the preservation effect of the food in the fresh-keeping bag. During the air extraction process, as the air in the fresh-keeping bag is extracted, the food is squeezed in the fresh-keeping bag. Since the amount of air in fresh-keeping bags of different sizes is different, and the squeezing tolerance of different types of food is also different, the air extraction amount of the air extraction component is controlled according to the identification information of the food to be packaged and the identification information of the fresh-keeping bag, so that the air extraction amount is adapted to the identification information of the fresh-keeping bag, and the air extraction amount is also adapted to the squeezing tolerance of the food, thereby improving the preservation and storage effect of the food.

[0094] Optionally, the processor obtains identification information of the food to be packaged, including: the processor obtains identification information of the food to be packaged sent by a camera.

[0095] Optionally, the identification information of the food to be packaged includes: the type of the food to be packaged.

[0096] Optionally, the processor controls the air extraction amount of the air extraction component according to the identification information of the food to be packaged and the identification information of the fresh-keeping bag, including: the processor controls the air extraction time of the air extraction pump according to the identification information of the food to be packaged and the identification information of the fresh-keeping bag. In this way, the air extraction amount of the air extraction component depends on the air extraction time of the air extraction pump, so the air extraction time of the air extraction pump is controlled according to the identification information of the food to be packaged and the identification information of the fresh-keeping bag, so that the air extraction amount is adapted to the identification information of the fresh-keeping bag and the food to be packaged, further improving the preservation and storage effect of the food and reducing energy consumption.

[0097] Exemplarily, the types of food to be packaged are divided into pressure-resistant type and non-pressure-resistant type; among them, the corresponding air extraction time of the pressure-resistant type and the first range is 5 seconds, the corresponding air extraction time of the pressure-resistant type and the second range is 9 seconds, and the corresponding air extraction time of the pressure-resistant type and the third range is 15 seconds; the corresponding air extraction time of the non-pressure-resistant type and the first range is 3 seconds, the corresponding air extraction time of the non-pressure-resistant type and the second range is 6 seconds, and the corresponding air extraction time of the non-pressure-resistant type and the third range is 9 seconds. The pressure-resistant type has a higher tolerance to extrusion, so when the identification information of the food is the pressure-resistant type, and the identification information of the fresh-keeping bag is in the first range, the volume of the fresh-keeping bag is relatively small at this time, but the tolerance of the food to extrusion is relatively high, so the air extraction time is controlled to 5 seconds, and the air in the fresh-keeping bag is extracted to the maximum extent, so that the preservation effect of the food is improved. The non-pressure-resistant type has a lower tolerance to extrusion. Therefore, when the identification information of the food is non-pressure-resistant and the identification information of the fresh-keeping bag is in the first range, the volume of the fresh-keeping bag is relatively small and the tolerance of the food to extrusion is relatively low. Therefore, the vacuum time is controlled to be 3 seconds. While extracting the air in the fresh-keeping bag, the degree of extrusion of the food is reduced to avoid the food being squeezed, deformed and damaged.

[0098] Exemplarily, meat and fruit ingredients are pressure-resistant, while vegetable and pastry ingredients are not pressure-resistant.
