Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a device for managing refrigerator food ingredients and a refrigerator. Background Art

[0002] At present, centralized purchasing has become a new lifestyle for people, and refrigerators have become a necessity for people at home as food safes. However, refrigerators have difficulty identifying the types and quantities of food in the refrigerator, making it difficult to manage food, which can easily lead to users forgetting that food has expired, and refrigerators have difficulty controlling the cooling capacity according to the types and quantities of food, and the degree of intelligence is low.

[0003] The related technology discloses a refrigerator with food management function. The refrigerator uses the principle of infrared thermal imaging. Its essence is to measure the temperature of the food through infrared thermal sensing to see if it is higher than the set temperature of the refrigerator. If it is higher than the set temperature of the refrigerator, the compressor is started for refrigeration.

[0004] The so-called food type recognition is only the recognition of the two-dimensional outline of the food. When the food is stacked or bagged, it will not be able to display the exact outline of the food, let alone accurately identify the type and quantity of the food.

[0005] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0006] Infrared radar technology mainly identifies food types through food contours and infrared spectra. In addition to being unable to accurately distinguish between foods of similar shapes such as apples, pears, oranges, and tangerines, the recognition accuracy and precision will also be greatly reduced when the temperatures of the foods are similar or the foods are stacked, and this problem cannot be solved through algorithms.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0011] In some embodiments, the refrigerator includes the device for managing refrigerator food.

[0012] The device for managing refrigerator food and the refrigerator provided by the embodiments of the present disclosure can achieve the following technical effects:

[0013] By moving the first millimeter-wave radar detection system on the first side of the refrigerator compartment and the second millimeter-wave radar detection system on the second side of the refrigerator compartment opposite to the first side, detection of all refrigerator compartments of the refrigerator can be achieved. Moreover, since the first millimeter-wave radar detection system and the second millimeter-wave radar detection system move along the first numerically controlled slide rail system and the second numerically controlled slide rail system, millimeter-wave signals are transmitted to foods at different positions in the refrigerator compartment and millimeter-wave signals reflected by foods in the refrigerator compartment are received, which is equivalent to transmitting and receiving millimeter-wave signals from a large-aperture antenna, and can be equivalent to a synthetic large-aperture antenna, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0041] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0043] Combination Figures 1 to 4 As shown, the embodiment of the present disclosure provides a device for managing refrigerator food, including a first millimeter wave radar detection system 1, a first numerical control slide rail system 2, a second millimeter wave radar detection system 3 and a second numerical control slide rail system 4. The first millimeter wave radar detection system 1 is arranged on the first side of the refrigerating chamber, and is used to transmit millimeter wave signals to the food in the refrigerating chamber and receive millimeter wave signals reflected by the food in the refrigerating chamber. The first numerical control slide rail system 2 is arranged on the first side of the refrigerating chamber, connected to the first millimeter wave radar detection system 1, and is used to carry the first millimeter wave radar detection system 1 and move on the first side of the refrigerating chamber. The second millimeter wave radar detection system 3 is arranged on the second side of the refrigerating chamber, and is used to transmit millimeter wave signals to the food in the refrigerating chamber and receive millimeter wave signals reflected by the food in the refrigerating chamber. The second numerical control slide rail system 4 is arranged on the second side of the refrigerating chamber, connected to the first millimeter wave radar detection system 1, and is used to carry the second millimeter wave radar detection system 3 and move on the second side of the refrigerating chamber. Wherein, the first side is opposite to the second side.

[0044] By adopting the device for refrigerator food management provided by the embodiment of the present disclosure, the first numerical control slide system 2 carries the first millimeter-wave radar detection system 1 and moves on the first side of the refrigerator chamber, and the second numerical control slide system 4 carries the second millimeter-wave radar detection system 3 and moves on the second side of the refrigerator chamber opposite to the first side, so as to realize detection of all refrigeration compartments of the refrigerator, and since the first millimeter-wave radar detection system 1 and the second millimeter-wave radar detection system 3 move along the first numerical control slide system 2 and the second numerical control slide system 4, millimeter-wave signals are transmitted to food at different positions in the refrigerator chamber, and millimeter-wave signals reflected by food in the refrigerator chamber are received, which is equivalent to transmitting and receiving millimeter-wave signals from a large-aperture antenna, and can be equivalent to a synthetic large-aperture antenna, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0045] It can be understood that the first millimeter-wave radar detection system 1 and the second millimeter-wave radar detection system 3 are relatively arranged on opposite sides of the refrigerating chamber and move synchronously, so that the detection ends of the two are relatively arranged on opposite sides of the refrigerating chamber and move synchronously.

[0046] Optionally, the moving direction of the first millimeter wave radar detection system 1 and the second millimeter wave radar detection system 3 is the vertical direction of the refrigerating chamber. In this way, it is beneficial to detect the food in each separated storage area of ​​the refrigerating chamber having multiple layers of separated storage areas in the vertical direction.

[0047] Of course, in the scenario of being applied to a refrigerated room having a plurality of partitioned storage areas in a lateral direction, the moving direction of the first millimeter-wave radar detection system 1 and the second millimeter-wave radar detection system 3 is the lateral direction of the refrigerated room.

[0048] This is conducive to detecting the food in each transversely divided storage area.

[0049] Optionally, the first millimeter wave radar detection system and / or the second millimeter wave radar detection system include: a millimeter wave antenna module and a radar chip cascade module. The millimeter wave antenna module is used to transmit millimeter wave signals to the food in the refrigerated compartment and receive millimeter wave signals reflected by the food in the refrigerated compartment. The radar chip cascade module is electrically connected to the millimeter wave antenna module and is used to transmit millimeter wave signals to the millimeter wave antenna module and receive millimeter wave signals transmitted by the millimeter wave antenna module.

[0050] In this way, the first millimeter wave radar detection system 1 and / or the second millimeter wave radar detection system 3, including a millimeter wave antenna module and a radar chip cascade module, can transmit millimeter wave signals to food at different positions in the refrigerator and receive millimeter wave signals reflected by food in the refrigerator, which is equivalent to transmitting / receiving millimeter wave signals from a large aperture antenna on the first side and / or the second side of the refrigerator, and can be equivalent to a synthetic large aperture antenna on the first side and / or the second side of the refrigerator, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0051] Optionally, the length of the millimeter wave antenna module is smaller than the width of the first side and the second side of the inner wall of the refrigerating chamber.

[0052] This helps the millimeter wave antenna module to slide more smoothly laterally on the first side and the second side of the cold storage chamber, thereby improving the detection accuracy and data accuracy of food management.

[0053] Optionally, combined Figure 3As shown, the first millimeter wave radar detection system 1 includes: a first millimeter wave antenna module 11 and a first radar chip cascade module 12. The first millimeter wave antenna module 11 is used to transmit millimeter wave signals to the food in the refrigerator and receive millimeter wave signals reflected by the food in the refrigerator. The first radar chip cascade module 12 is electrically connected to the first millimeter wave antenna module 11, and is used to transmit millimeter wave signals to the first millimeter wave antenna module 11 and receive millimeter wave signals sent by the first millimeter wave antenna module 11.

[0054] In this way, transmitting millimeter wave signals to foods at different positions in the refrigerator and receiving millimeter wave signals reflected by foods in the refrigerator are equivalent to transmitting and receiving millimeter wave signals from a large-aperture antenna, which can be equivalent to a synthetic large-aperture antenna, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0055] Specifically, the first millimeter-wave radar chip cascade module is electrically connected to the power supply 6 and the processor 5 , and the first slide rail system is electrically connected to the power supply 6 and the processor 5 .

[0056] In this way, the first millimeter-wave radar detection system 1 includes a first millimeter-wave antenna module 11 and a first radar chip cascade module 12, which can transmit millimeter-wave signals to foods at different positions in the cold storage room and receive millimeter-wave signals reflected by foods in the cold storage room, which is equivalent to transmitting / receiving millimeter-wave signals from a large-aperture antenna on the first side of the cold storage room, and can be equivalent to a synthetic large-aperture antenna on the first side of the cold storage room, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0059] In this way, multiple radar chips are cascaded and connected to the millimeter-wave antenna arrays respectively, which is beneficial to increase the number of transmitting channels and receiving channels and greatly simplifies the control of the first millimeter-wave radar detection system 1.

[0060] Optionally, the first millimeter wave antenna array 111 includes: a first transmitting antenna, a first receiving antenna and a first isolation antenna.

The first receiving antenna is connected to the transmitting channel of the first radar chip 121, and is used to receive the millimeter wave signals reflected by the food in the refrigerator. The first isolation antenna is connected to the first radar chip 121.

[0061] In this way, the first radar chip 121 is advantageously enabled to better transmit millimeter wave signals to food at different positions in the refrigerating chamber and receive millimeter wave signals reflected by food in the refrigerating chamber.

[0062] Optionally, the second millimeter wave antenna array 112 includes: a second transmitting antenna, a second receiving antenna, and a second isolation antenna.

The second isolation antenna is connected to the second radar chip 122.

[0063] This helps the second radar chip 122 to better transmit millimeter wave signals to food at different locations in the refrigerated room and receive millimeter wave signals reflected by food in the refrigerated room.

[0064] Optionally, the third millimeter wave antenna array 113 includes: a third transmitting antenna, a third receiving antenna and a third isolation antenna. The third transmitting antenna is connected to the receiving channel of the third radar chip 123, and is used to transmit millimeter wave signals to the food in the refrigerator. The third receiving antenna is connected to the transmitting channel of the third radar chip 123, and is used to receive the millimeter wave signals reflected by the food in the refrigerator. The third isolation antenna is connected to the third radar chip 123.

[0065] This helps the third radar chip 123 to better transmit millimeter wave signals to food at different locations in the refrigerated room and receive millimeter wave signals reflected by food in the refrigerated room.

[0066] Optionally, the fourth millimeter wave antenna array 114 includes: a fourth transmitting antenna, a fourth receiving antenna and a fourth isolation antenna. The fourth transmitting antenna is connected to the receiving channel of the fourth radar chip 124 and is used to transmit millimeter wave signals to the food in the refrigerator. The fourth receiving antenna is connected to the transmitting channel of the fourth radar chip 124 and is used to receive the millimeter wave signals reflected by the food in the refrigerator. The fourth isolation antenna is connected to the fourth radar chip 124.

[0067] In this way, the fourth radar chip 124 is advantageously enabled to better transmit millimeter wave signals to food at different positions in the refrigerated room and receive millimeter wave signals reflected by food in the refrigerated room.

[0068] Specifically, the first radar chip 121, the second radar chip 122, the third radar chip 123, and the fourth radar chip 124 can all be AWR2243 radar chips. The AWR2243 radar chip is an integrated single-chip FMCW (Frequency Modulated Continuous Wave) transceiver capable of operating in the 76 GHz to 81 GHz frequency band, with 3 transmit channels and 4 receive channels. The first radar chip cascade module 12 includes 12 transmit channels and 16 receive channels. The receive channel of the first radar chip 121 is connected to the first receive antenna, and the transmit channel is connected to the first transmit antenna.

The receive channel of the fourth radar chip 124 is connected to the fourth receive antenna, and the transmit channel is connected to the fourth transmit antenna.

[0069] In this way, four AWR2243 radar chips are cascaded, so that the first radar chip cascade module 12 includes 12 transmitting channels and 16 receiving channels. The 12 transmitting channels and 16 receiving channels are respectively connected to the millimeter wave antenna array, which is beneficial to increase the number of transmitting channels and receiving channels and greatly simplifies the control of the first millimeter wave radar detection system 1.

[0070] Optionally, the first CNC slide rail system 2 includes: a first CNC slide rail 21 and a first CNC slider 22. The first CNC slide rail 21 is arranged on the first side of the cold storage chamber. The first CNC slider 22 is slidably connected to the first CNC slide rail 21, and the first millimeter-wave radar detection system 1 is fixed on the first CNC slider 22 and can be controlled to move along the first CNC slide rail 21. Specifically, the first radar chip cascade module 12 is fixed on the first CNC slider 22, and the first end of the first millimeter-wave antenna module 11 is fixed on the first CNC slider 22.

[0071] In this way, it is beneficial to move the first millimeter-wave radar detection system 1 on the first side of the cold storage room to transmit millimeter-wave signals to food at different positions in the cold storage room and receive millimeter-wave signals reflected by the food in the cold storage room, which is equivalent to transmitting and receiving millimeter-wave signals from a large-aperture antenna on the first side of the cold storage room. It can be equivalent to a synthetic large-aperture antenna on the first side of the cold storage room, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0072] Optionally, the length of the first numerically controlled slide rail 21 is smaller than the height of the first side of the inner wall of the refrigerating chamber.

[0073] In this way, it is beneficial to better arrange the first numerically controlled slide rail 21 on the first side of the refrigerator refrigerating chamber.

[0074] Optionally, each time the first numerically controlled sliding block moves a set distance along the first numerically controlled sliding rail 21, the first millimeter wave radar detection system 1 transmits a millimeter wave signal to the food in the refrigerator once and receives a millimeter wave signal reflected by the food in the refrigerator once. Specifically, the value of the set distance may be 1 mm.

[0075] This is conducive to more accurately moving the first millimeter-wave radar detection system 1 on the first side of the cold storage room, so that millimeter-wave signals can be more evenly transmitted to foods at different positions in the cold storage room and millimeter-wave signals reflected by foods in the cold storage room can be received, which is equivalent to transmitting and receiving millimeter-wave signals from a large-aperture antenna on the first side of the cold storage room. A synthetic large-aperture antenna can be more accurately realized on the first side of the cold storage room, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0076] Optionally, the first CNC slide rail system 2 further includes: a first auxiliary slide rail 24 and a first slide rail bracket 23. The first auxiliary slide rail 24 is arranged on the first side of the cold storage chamber and opposite to the first CNC slide rail 21, and the first millimeter wave radar detection system 1 is slidably connected to the first auxiliary slide rail 24. The first slide rail bracket 23 is used to fix and support the first auxiliary slide rail 24. Specifically, the second end of the first millimeter wave antenna module 11 is slidably connected to the first auxiliary slide rail 24.

[0077] In this way, it is helpful to support the first millimeter wave radar detection system 1 so that the first millimeter wave radar detection system 1 is in the same plane when sliding, thereby improving the detection accuracy and data accuracy of food management. Optionally, the length of the first auxiliary slide rail 24 is the same as the length of the first CNC slide rail 21.

[0078] This is conducive to better supporting the first millimeter-wave radar detection system 1, so that the first millimeter-wave radar detection system 1 is in the same plane when sliding, thereby improving the detection accuracy and data accuracy of food management.

[0080] Specifically, the second millimeter-wave radar chip cascade module is electrically connected to the power supply 6 and the processor 5 , and the second slide rail system is electrically connected to the power supply 6 and the processor 5 .

[0090] This helps the seventh radar chip 323 to better transmit millimeter wave signals to food at different locations in the refrigerated room and receive millimeter wave signals reflected by food in the refrigerated room.

[0091] Optionally, the eighth millimeter wave antenna array 314 includes: an eighth transmitting antenna, an eighth receiving antenna and an eighth isolation antenna. The eighth transmitting antenna is connected to the receiving channel of the eighth radar chip 324, and is used to transmit millimeter wave signals to the food in the refrigerator. The eighth receiving antenna is connected to the transmitting channel of the eighth radar chip 324, and is used to receive the millimeter wave signals reflected by the food in the refrigerator. The eighth isolation antenna is connected to the eighth radar chip 324.

[0092] This helps the eighth radar chip 324 to better transmit millimeter wave signals to food at different locations in the refrigerated room and receive millimeter wave signals reflected by food in the refrigerated room.

[0093] Specifically, the fifth radar chip 321, the sixth radar chip 322, the seventh radar chip 323, and the eighth radar chip 324 can all be AWR2243 radar chips. The second radar chip cascade module 32 includes 12 transmit channels and 16 receive channels. The receive channel of the fifth radar chip 321 is connected to the fifth receive antenna, and the transmit channel is connected to the fifth transmit antenna. The receive channel of the sixth radar chip 322 is connected to the sixth receive antenna, and the transmit channel is connected to the sixth transmit antenna. The receive channel of the seventh radar chip 323 is connected to the seventh receive antenna, and the transmit channel is connected to the seventh transmit antenna. The receive channel of the eighth radar chip 324 is connected to the eighth receive antenna, and the transmit channel is connected to the eighth transmit antenna.

[0094] In this way, four AWR2243 radar chips are cascaded, so that the second radar chip cascade module 32 includes 12 transmitting channels and 16 receiving channels, so that the 12 transmitting channels and 16 receiving channels are respectively connected to the millimeter wave antenna array, which is beneficial to increase the number of transmitting channels and receiving channels and greatly simplifies the control of the second millimeter wave radar detection system 3.

[0095] Optionally, the second CNC slide rail system 4 includes: a second CNC slide rail 41 and a second CNC slider 42. The first CNC slide rail 41 is arranged on the second side of the cold storage chamber. The second CNC slider 42 is slidably connected to the second CNC slide rail 42, and the second millimeter wave radar detection system 3 is fixed on the second CNC slider 42 and can be controlled to move along the second CNC slide rail 41. Specifically, the second radar chip cascade module 32 is fixed on the second CNC slider 42, and the first end of the second millimeter wave antenna module 31 is fixed on the second CNC slider 42.

[0096] In this way, it is beneficial to move the second millimeter-wave radar detection system 3 on the second side of the cold storage room to transmit millimeter-wave signals to food at different positions in the cold storage room and receive millimeter-wave signals reflected by the food in the cold storage room, which is equivalent to transmitting and receiving millimeter-wave signals from a large-aperture antenna on the second side of the cold storage room. It can be equivalent to a synthetic large-aperture antenna on the second side of the cold storage room, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0097] Optionally, the length of the second numerically controlled slide rail 41 is smaller than the height of the second side of the inner wall of the refrigerating chamber.

[0098] This is conducive to better arranging the second numerically controlled slide rail 21 on the second side of the refrigerator refrigerating chamber.

[0099] Optionally, each time the second numerical control slider 42 moves a set distance along the second numerical control rail 41, the second millimeter wave radar detection system 3 transmits a millimeter wave signal to the food in the refrigerator once and receives a millimeter wave signal reflected by the food in the refrigerator once. Specifically, the value of the set distance may be 1 mm.

[0100] This is conducive to more accurately moving the second millimeter-wave radar detection system 3 on the second side of the cold storage room, so that millimeter-wave signals can be more evenly transmitted to foods at different positions in the cold storage room and millimeter-wave signals reflected by foods in the cold storage room can be received. This is equivalent to transmitting and receiving millimeter-wave signals from a large-aperture antenna on the second side of the cold storage room, and can more accurately be equivalent to a synthetic large-aperture antenna on the second side of the cold storage room, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0101] Optionally, the second CNC slide rail system 4 further includes: a second auxiliary slide rail 44 and a second slide rail bracket 43. The second auxiliary slide rail 44 is arranged on the second side of the cold storage chamber and opposite to the second CNC slide rail 41, and the second millimeter wave radar detection system 3 is slidably connected to the second auxiliary slide rail 44. The second slide rail bracket 43 is used to fix and support the second auxiliary slide rail 44. Specifically, the second end of the second millimeter wave antenna module 31 is slidably connected to the second auxiliary slide rail 44.

[0102] This is conducive to supporting the second millimeter-wave radar detection system 3 so that the second millimeter-wave radar detection system 3 is in the same plane when sliding, thereby improving the detection accuracy and data accuracy of food management.

[0103] Optionally, the length of the second auxiliary slide rail 44 is the same as the length of the second CNC slide rail 41 .

[0104] This is conducive to better supporting the second millimeter-wave radar detection system 3, so that the second millimeter-wave radar detection system 3 is in the same plane when sliding, thereby improving the detection accuracy and data accuracy of food management.

[0105] Combination Figure 7 As shown, an embodiment of the present disclosure provides a refrigerator 7, including a device 8 for managing refrigerator food.

[0106] With the refrigerator provided by the embodiment of the present disclosure, detection of all refrigerated compartments of the refrigerator is achieved by moving the first millimeter-wave radar detection system 1 equipped with the first numerically controlled slide rail system 2 on the first side of the refrigerated chamber and the second millimeter-wave radar detection system 3 equipped with the second numerically controlled slide rail system 4 on the second side of the refrigerated chamber opposite to the first side. Moreover, since the first millimeter-wave radar detection system 1 and the second millimeter-wave radar detection system 3 move along the first numerically controlled slide rail system 2 and the second numerically controlled slide rail system 4, millimeter-wave signals are transmitted to food at different positions in the refrigerated chamber and millimeter-wave signals reflected by the food in the refrigerated chamber are received, which is equivalent to transmitting and receiving millimeter-wave signals from a large-aperture antenna, and can be equivalent to a synthetic large-aperture antenna, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.
