[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0037] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0038] In the related technology, the oxygen reduction capacity is poor, which makes food easy to age and rot. The refrigerators in the industry can only reduce the oxygen concentration to about 15%, which cannot meet the needs of preserving food. The oxygen concentration must be reduced to at least 10% to have a fresh-keeping effect on food. At present, the industry has not been able to reduce the oxygen concentration to 10%.

[0039] In order to solve the above technical problems, the present application provides a refrigerator drawer, which uses an oxygen reduction and pressure reduction device to achieve oxygen reduction and pressure reduction functions, thereby reducing the oxygen concentration in the drawer assembly to 8%, delaying food spoilage and maintaining the freshness of food. The oxygen reduction and pressure reduction device is driven by a driving mechanism to achieve automatic and intelligent driving.

[0040] In some exemplary embodiments, Figure 1-Figure 4 As shown, a refrigerator drawer is installed in a refrigerator. For example, the refrigerator may have a refrigerator compartment, a freezer compartment, etc. The refrigerator drawer can be placed in the refrigerator compartment and the freezer compartment to store food. Among them, the refrigerator drawer in the refrigerator compartment can provide a fresh-keeping function for food, delaying its aging and corruption, and the food is, for example, fruits and vegetables. The refrigerator has a box body, and a storage space is provided in the box body for placing the refrigerator drawer.

[0041] In this embodiment, if Figure 1-Figure 4 As shown, the refrigerator drawer includes a drawer assembly 1, an oxygen reduction and pressure reduction device 2, a driving mechanism 3 and a detection assembly 4. The oxygen reduction and pressure reduction device 2 is installed on the drawer assembly 1 to realize the oxygen reduction and pressure reduction functions in the drawer assembly 1, thereby reducing the oxygen concentration in the drawer assembly 1. The driving mechanism 3 is connected to the oxygen reduction and pressure reduction device 21 to drive the oxygen reduction and pressure reduction device 2 to work.

[0042] The drawer assembly 1 is provided with a storage space 13 for storing food. The drawer assembly 1 includes, for example, a drawer box 11 and a drawer cover 12. The drawer box 11 is used to store food for storage, and the opening of the drawer box 11 can be set at the upper side, for example, to facilitate users to take and place food. The storage space 13 is formed in the drawer cover 12, and the opening of the storage space 13 is located at the side of the drawer cover 12, so as to facilitate pushing and pulling the drawer box 11. When the drawer box 11 is placed in the drawer cover 12, a closed storage space 13 can be formed.

[0043] It should be noted that the above-mentioned drawer 11 may also be provided with some auxiliary components to facilitate pushing, pulling or installing the drawer 11. For example, a handle 111 is provided on the front side of the drawer 11 to provide a force application position for the user to facilitate pushing and pulling the drawer 11. Alternatively, an auxiliary component such as a roller is provided on the lower side of the drawer 11 to reduce resistance and improve smoothness. The drawer cover 12 may also be provided with a track that cooperates with the roller to limit the roller to ensure that the drawer 11 can move along a preset direction, which is subject to actual conditions.

[0044] In this embodiment, if Figure 1-Figure 4 As shown, the oxygen reduction and pressure reduction device 2 is installed to the drawer assembly 1 to improve the reliability of the oxygen reduction and pressure reduction device 2. The oxygen reduction and pressure reduction device 2 is connected to the accommodating space 13 to facilitate the extraction of gas inside the accommodating space 13. The gas is, for example, oxygen or air, thereby achieving the purpose of oxygen reduction and pressure reduction.

[0045] The driving mechanism 3 is connected to the oxygen reduction and pressure reduction device 2, and is used to drive the gas in the accommodating space 13 to flow into the oxygen reduction and pressure reduction device 2, so that the oxygen or air inside the accommodating space 13 is extracted to achieve automatic operation.

[0046] The driving mechanism 3 includes, for example, a vacuum pump 31, a first main pipeline 32 and a connecting valve 33. The vacuum pump 31 is connected to the first main pipeline 32, and the first main pipeline 32 is connected to the oxygen reduction and pressure reduction device 2 through the connecting valve 33. The vacuum pump 31 can quickly extract the gas in the accommodating space 13 to achieve the required vacuum level, and can also operate stably even in harsh environments such as low temperature, with strong corrosion resistance and anti-interference ability, without obvious noise and vibration, so as to improve the user's comfort during operation and avoid interference to the user.

[0047] In this embodiment, if Figure 1-Figure 4 As shown, the detection component 4 is, for example, disposed in the accommodating space 13 to detect the parameters in the accommodating space 13. The detection component 4 is, for example, an integrated sensor, and the environmental parameters detected by the detection component 4 may include, for example, at least one of humidity, temperature, vacuum degree, and gas content, so as to monitor the changes in the accommodating space 13 in real time and adjust the internal environment of the accommodating space 13 in time so that the purpose of preservation or freshness can be achieved. The detection component 4 is, for example, disposed on the inner side wall of the drawer cover 12, and is disposed close to the lower side and away from the oxygen reduction and pressure reduction device 2 to improve the accuracy of the measurement.

[0048] In this embodiment, if Figure 1-Figure 4 As shown, the oxygen reduction and pressure reduction device 2 includes an oxygen reduction component 21 and a pressure reduction component 22. The oxygen reduction component 21 is connected to the accommodating space 13 and the driving mechanism 3 respectively to achieve the purpose of extracting oxygen.

[0049] Exemplarily, the deoxygenation component 21 includes a deoxygenation part 211, a first pipe 212 and a first valve 213, and the deoxygenation part 211 is connected to the accommodating space 13, so that the gas in the accommodating space 13 can flow through the deoxygenation part 211 to achieve gas separation. Among them, the deoxygenation part 211 includes a shell 2111 and a gas separation part 2112, and the gas separation part 2112 is arranged in the shell 2111. Among them, the gas separation part 2112 is used to separate hydrogen and oxygen in the air, so that hydrogen is left in the accommodating space 13, and oxygen is extracted to reduce the oxygen concentration in the accommodating space 13. The gas separation part 2112 is, for example, a hollow fiber membrane, which has efficient separation performance, good mechanical strength and pressure resistance, is not easy to break or deform, is suitable for high-pressure operating environments, is easy to clean and maintain, and extends its service life. It can be used repeatedly and reduces costs.

[0050] The deoxygenation part 211 is fixed on the top of the drawer outer cover 12, for example. The drawer outer cover 12 can support the deoxygenation part 211, and the deoxygenation part 211 can be fixed on the drawer outer cover 12 by bonding or screwing, so as to improve the reliability of the connection of the deoxygenation part 211 and avoid its deviation, which affects the patency of its gas flow channel.

[0051] One end of the first pipeline 212 is connected to the oxygen reduction part 211, and the other end of the first pipeline 212 is connected to the connecting valve 33 to ensure the patency of the oxygen reduction flow channel. The first valve 213 is arranged on the first pipeline 212, and the first valve 213 is, for example, a solenoid valve, which can control the opening and closing of the first pipeline 212, and the solenoid valve can achieve precise control.

[0052] The first pipeline 212 includes a first section 2121 and a second section 2122. The first section 2121 is extended along the top of the drawer assembly 1, one end of which is connected to the oxygen reduction unit 211, and the other end is connected to the second section 2122. The second section 2122 is extended along the side of the drawer assembly 1 and is connected to the connecting valve 33 of the driving mechanism 3. The first section 2121 and the second section 2122 can be connected to each other by a first two-way valve 2123, which has a simple structure and stable performance, and can also realize the connection and disconnection of the first section 2121 and the second section 2122.

[0053] The decompression assembly 22 is respectively connected with the accommodating space 13 and the driving mechanism 3. The decompression assembly 22 includes a second two-way valve 221, a second pipe 222 and a second valve 223. The second two-way valve 221 is buckled on the top of the drawer assembly 1 and is connected with the accommodating space 13. One end of the second pipe 222 is connected with the second two-way valve 221. The second valve 223 is, for example, an electronic valve, which is arranged on the second pipe 222 to control the on and off of the second pipe 222. The other end of the second pipe 222 is connected with the connecting valve 33 of the driving mechanism 3. The connecting valve 33 is, for example, a three-way valve, which realizes multiple flow channels, so that the decompression assembly 22 and the oxygen reduction assembly 21 are connected respectively without interfering with each other, and has multifunctionality and flexibility, meeting the needs of air extraction in the change flow channel.

[0054] The second pipeline 222 includes, for example, a third section 2221 and a fourth section 2222. The third section 2221 is extended along the top of the drawer assembly 1, one end of which is connected to the second two-way valve 221, and the other end is connected to the fourth section 2222. The fourth section 2222 is extended along the side of the drawer assembly 1 and is connected to the connecting valve 33 of the driving mechanism 3. The third section 2221 and the fourth section 2222 can be connected to each other by, for example, the third two-way valve 2223, which has a simple structure and stable performance, and can also realize the connection and disconnection of the third section 2221 and the fourth section 2222.

[0055] In this embodiment, if Figure 1-Figure 4As shown, the deoxygenation component 21 includes, for example, a blowing member 214, which is disposed in the accommodating space 13, and is used to blow the gas in the accommodating space 13 to improve the air extraction efficiency. The blowing member 214 is, for example, a fan, and the fan can be one or more, and the multiple fans can be arranged in sequence along the horizontal direction of the side, or can be arranged in sequence along the vertical direction of the side. The blowing member 214 can increase the flow rate of the airflow, speed up the deoxygenation efficiency, and can also blow away the nitrogen trapped on the surface of the deoxygenation part 211 to prevent the nitrogen from adhering to the deoxygenation part 211 and affecting the deoxygenation effect of the air.

[0056] In this embodiment, if Figure 1-Figure 4 As shown, a partition plate 14 is disposed in the accommodating space 13. The partition plate 14 is placed vertically and fixedly connected to the inner wall of the drawer cover 12 to improve the stability and reliability of the partition plate 14. The partition plate 14 divides the accommodating space 13 into a first accommodating space 131 and a second accommodating space 132. The partition plate 14 is provided with a plurality of through holes 141 to connect the first accommodating space 131 and the second accommodating space 132.

[0057] The oxygen reduction part 211 is connected to the first accommodation space 131, and the blowing member 214 is disposed in the second accommodation space 132 and fixedly connected to the inner wall of the drawer cover 12. The fan blades of the blowing member 214 face the through hole 141, so as to blow the airflow in the second accommodation space 132 to flow to the first accommodation space 131, and the gas in the first accommodation space 131 is continuously extracted.

[0058] The drawer assembly 1 equipped with the oxygen reduction function has good sealing performance, which makes the humidity inside the drawer assembly 1 high, which is very likely to cause condensation and cause the stored food to spoil. Therefore, the drawer assembly 1 is provided with an air inlet 121 and an air outlet 122, and the air inlet 121 and the air outlet 122 are respectively connected to the second accommodating space 132 to balance the temperature and humidity of the second accommodating space 132. The air inlet 121 is, for example, arranged on the rear side wall of the drawer cover 12, and is arranged close to the upper side. The air outlet 122 is arranged on the rear side wall of the drawer cover 12, and is arranged close to the lower side. Since condensation of wet air will gather at the bottom if it is generated inside, therefore, the air outlet 122 is arranged at the bottom, which can quickly alleviate the problem of high humidity caused by low temperature.

[0059] When the humidity of the accommodating space 13 is high, the air inlet 121 is opened to reduce the temperature in the second accommodating space 132 to reach the dew point temperature. The humid air in the second accommodating space 132 condenses and collects at the bottom, thereby reducing the temperature of the accommodating space 13 .

[0060] In this embodiment, if Figure 1-Figure 4As shown, a temperature detection element 133 is provided in the second accommodation space 132 to monitor the temperature of the second accommodation space 132 in real time. Whether to open the air inlet 121 and the air outlet 122 is determined based on the temperature of the second accommodation space 132.

[0061] The present application also provides a refrigerator, including a refrigerator drawer as in the above embodiment. The refrigerator may have a refrigerator compartment, a freezer compartment, etc., and the refrigerator drawer may be placed in the refrigerator compartment and the freezer compartment to store food. Among them, the refrigerator drawer in the refrigerator compartment can provide a fresh-keeping function for food, delaying its aging and corruption, and the food is, for example, fruits and vegetables. The refrigerator has a box body, and a storage space is provided in the box body for placing the refrigerator drawer.

[0062] By using an oxygen reduction and pressure reduction device to first reduce oxygen, the oxygen content in the accommodating space is reduced to 10%, and then the pressure is reduced and vacuumed to 80% vacuum degree, which can effectively reduce the oxygen concentration in the accommodating space to 8%, achieving technological progress.

[0063] A partition is provided to separate the accommodating space into a first accommodating space and a second accommodating space, and the humidity of the accommodating space is controlled by utilizing the temperature difference to avoid condensation evaporation and food corruption due to excessive humidity.

[0064] In some exemplary embodiments, the present application also provides a control method, which is applied to a refrigerator drawer as in the above embodiments. The control method can be installed in a control module of the refrigerator to control the refrigerator drawer.

[0065] like Figure 5 As shown, the control method includes:

[0066] S110: Obtain environmental parameters in the accommodation space.

[0067] In step S110, the interior of the accommodation space is inspected by using a detection component to determine the environmental parameters in the accommodation space, wherein the environmental parameters include at least one of humidity, temperature, vacuum degree and gas content. The detection component is, for example, an integrated sensor, which can monitor the temperature, humidity, vacuum degree and gas content in the accommodation space in real time, and the gas content is, for example, oxygen content.

[0068] The control module can obtain the environmental parameters collected by the detection component and analyze and process them.

[0069] S120: Based on environmental parameters, turn on or off the oxygen reduction and pressure reduction device.

[0070] In step S120, the control module determines whether to turn on or off the oxygen reduction and pressure reduction device based on the environmental parameters to achieve automated and intelligent oxygen reduction and pressure reduction to improve the accuracy of the oxygen reduction and pressure reduction process.

[0071] Some examples include Figure 1-Figure 4 As shown, the environmental parameter is, for example, the gas content, and the gas is, for example, oxygen. If the oxygen concentration is, for example, greater than 10%, the oxygen reduction component 21 and the driving mechanism 3 are turned on, and the decompression component 22 remains closed. The oxygen reduction component 21 is turned on, for example, by opening the first valve 213 to ensure the patency of the first pipeline 212, and by turning on the blowing member 214 to blow the gas in the accommodating space 13 to improve the oxygen reduction efficiency.

[0072] The driving mechanism 3 extracts gas outward, and the oxygen reduction unit 211 separates oxygen and nitrogen in the air, so that oxygen is extracted and hydrogen is retained in the accommodating space 13. Nitrogen will not accelerate the aging and decay of food, and effectively slows down oxidation and the growth of microorganisms, thereby extending the shelf life of food. Nitrogen is an inert gas and will not react chemically with food, so it can achieve the purpose of food preservation, allowing food to maintain its original flavor and taste, and enhance the user experience. At the same time, by utilizing the nitrogen separated from the air in the accommodating space, there is no need to charge nitrogen separately, which realizes the utilization of resources and reduces costs.

[0073] In other examples, such as Figure 1-Figure 4 As shown, the environmental parameters include oxygen content and vacuum degree, and if the oxygen concentration is less than or equal to 10%, the oxygen reduction component 21 is closed and the decompression component 22 is opened. Closing the oxygen reduction component 21 is, for example, closing the first valve 213 to disconnect the first pipeline 212, and closing the blowing member 214.

[0074] Opening the decompression component 22, for example, is opening the second valve 223, and using the driving mechanism 3 to extract gas so that the gas enters the decompression component 22 to achieve the purpose of vacuuming. When the vacuum degree reaches 80%, the vacuuming is stopped.

[0075] It should be noted that when vacuuming, if the oxygen content is greater than or equal to 10%, the decompression component 22 is closed and the oxygen reduction component 21 is opened to achieve the purpose of reducing oxygen first and then reducing pressure. Reducing oxygen first and then reducing pressure can reduce the oxygen concentration to 8%, thereby improving the oxygen reduction effect.

[0076] In other examples, such as Figure 1-Figure 4 As shown, the environmental parameters include temperature, humidity, vacuum degree and oxygen content. If the vacuum degree is less than or equal to 80%, and the oxygen concentration is less than or equal to 8%, the decompression component 22 and the oxygen reduction component 21 are closed.

[0077] The humidity of the accommodation space 13 is obtained. If the humidity of the accommodation space 13 is greater than 95%, the air inlet 121 and the air outlet 122 are opened to quickly dissipate heat, so that the temperature in the accommodation space 13 is reduced to 3° C. For air at 5° C., when the relative humidity is 95%, the dew point is 4° C.; when the relative humidity is 90%, the dew point is 3° C.

[0078] The detection component 4 in the first accommodating space 131 and the temperature detection component 133 in the second accommodating space 132 can both detect the temperature to improve the accuracy of monitoring.

[0079] It should be noted that when cooling and dehumidifying, the oxygen content and vacuum degree must be monitored at all times. If the oxygen content is greater than or equal to 10%, the oxygen reduction component 21 is turned on. If the vacuum degree is greater than 80%, the pressure reduction component 22 is turned on. The execution method is the same as that in the above example, and will not be repeated here.

[0080] In this application, the opening and closing of the first valve and the second valve can effectively reduce the oxygen concentration in the accommodation space to 8% by "first reducing oxygen and then reducing pressure", and the oxygen concentration in the accommodation space is controlled not to rise by the control module. The second accommodation space is separated, and the temperature of the small-area second accommodation space is quickly adjusted to the dew point temperature by opening and closing the air inlet and the air outlet, thereby reducing the temperature of the accommodation space and avoiding food spoilage caused by condensation.
