[0049] Figure 1 This is a schematic diagram of a refrigerator according to one embodiment of the present invention;
[0050] Figure 2 This is a schematic diagram of a storage box according to an embodiment of the present invention;
[0051] Figure 3 This is a schematic diagram of a food ingredient management module according to an embodiment of the present invention. Specific Implementation
[0052] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.
[0053] See Figure 1 A refrigerator 100 provided in one embodiment of the present invention includes a cabinet and a door 101 for opening and closing the cabinet. A display screen 102 may be installed on the door 101. Specifically, a refrigerator compartment and a freezer compartment may be provided inside the cabinet, and the door 101 may include a refrigerator door for opening and closing the refrigerator compartment and a freezer door for opening and closing the freezer compartment. A food management module may be provided inside the refrigerator 100 to manage food information inside the refrigerator 100.
[0054] See Figure 2 , Figure 3 The food management module provided in the first embodiment of the present invention includes a preset identification device access position 110, an identification device 120 that can be accessed at the preset identification device access position 110, a color sensor 130, and an access status detection module 190. The color sensor 130 can be configured to collect the identification color information of the identification device 120, and the access status detection module 190 can be configured to detect the access status information of the identification device 120.
[0055] The food ingredient management module may further include a storage module 150 and a processing module 160. The storage module 150 is configured to store food ingredient information associated with the identification color information. The processing module 160 is connected to a color sensor 130, an access status detection module 190, and the storage module 150, and is configured to acquire the access status information. When the access status information changes, the processing module 160 acquires the identification color information and the food ingredient information associated with the identification color, and manages the food ingredient information associated with the identification color information according to the access status information, generating food ingredient storage data.
[0056] In this embodiment, the food management module can be an independent module separate from the refrigerator 100, and the food management module can communicate with the internal system of the refrigerator 100. Alternatively, it can be a module built into the system of the refrigerator 100, such as the food management module sharing the storage module 150 and the processing module 160 with the refrigerator 100.
[0057] Multiple preset labeling device access positions 110 and labeling devices 120 can be provided. Each preset labeling device access position 110 can be equipped with a color sensor 130 and an access status detection module 190. Each labeling device 120 can be placed in any preset labeling device access position 110. Users can remove the labeling device 120 from the preset labeling device access position 110 and attach it to the food before storing it in the refrigerator 100. When taking out the food, the user can remove the labeling device 120 attached to the food and put it back in any preset labeling device access position 110.
[0058] The preset identification device access position 110 can be set on the door 101 of the refrigerator 100, and the identification device 120 can be set as a pipe clamp. Specifically, a storage box 140 for storing pipe clamps can be set on the door 101 of the refrigerator 100. Several preset identification device access positions 110 can be set inside the storage box 140, and a color sensor 130 can be set on one inner wall of the storage box 140 at a position corresponding to the preset identification device access position 110.
[0059] The color information collected by the color sensor 130 can be the RGB values of the color. The marking device 120 can have color blocks, the color of which is the marking color of the marking device 120. Alternatively, the marking device 120 itself can be set as the marking color. The preset marking device access position 110 can be set with a preset background color, such as the color of the inner wall of the storage box 140 opposite to the color sensor 130. The marking color of the marking device 120 can be different from the preset background color. When the marking device 120 is stored in the preset marking device access position 110, the color sensor 130 can directly collect the marking color information of the marking device 120. When the preset marking device access position 110 is not occupied by the marking device 120, the color sensor 130 can directly collect the background color information.
[0060] The labeling device 120 can also be equipped with images or text representing food items, such as labels for apples or bananas. In this case, the storage module 150 can directly store the food item information represented by the labeling device 120. When a user stores food items in the refrigerator 100, they can directly access the corresponding labeling device 120. Of course, users can also change the food item information associated with the label color information stored in the storage module 150 according to their own needs.
[0061] The storage and retrieval status information can include storage and retrieval status. Storage status indicates that an identification device 120 is stored at the preset identification device storage / retrieval position 110, while retrieval status indicates that no identification device 120 is stored at the preset identification device storage / retrieval position 110. An indicator light 141 can also be provided at each preset identification device storage / retrieval position 110. The indicator light 141 can communicate with the storage and retrieval status detection module 190. The indicator light 141 emits a corresponding light according to the storage and retrieval status of the identification device 120; for example, it emits green light when stored and red light when retrieved. If the indicator light 141 does not change color when the user stores or retrieves the identification device 120, the user can preliminarily determine that the identification device 120 is not properly stored or that the identification device is malfunctioning. The user can then adjust the position of the identification device 120 or report a malfunction, thereby improving the accuracy of the identification.
[0062] When the access status information changes, it can be determined that the user has taken out the identification device 120 from the preset identification device access position 110 or put the identification device 120 into the preset identification device access position 110. This indicates that the user has put food into the refrigerator 100 or taken food out of the refrigerator 100. At this time, the identification color information of the identification device 120 can be obtained. The identification color information can be the color information collected by the color sensor 130 when the access status information changes, or it can be the color information collected by the color sensor 130 before and after the access status information changes. The color information that is different from the background color information is marked as the identification color information.
[0063] After obtaining the identification color information of the identification device 120, the food information associated with the identification color information can be queried in the storage module 150. If the access status information changes from the stored state to the retrieved state, that is, the user takes the identification device 120 out of the preset identification device access position 110, it can be determined that the user attaches the identification device 120 to the food and puts it into the refrigerator 100 for storage. At this time, the food information associated with the identification color information of the identification device 120 is the food information placed in the refrigerator 100. If the access status information changes from the retrieved state to the stored state, that is, the user puts the identification device 120 into the preset identification device access position 110, it can be determined that the user takes out the food from the refrigerator 100 and puts the identification device 120 attached to the food back into the preset identification device access position 110. At this time, the food information associated with the identification color information of the identification device 120 is the food information of the food taken out from the refrigerator 100.
[0064] Furthermore, in one embodiment of the present invention, the access status detection module 190 includes a pressure sensor disposed at the access position 110 of the preset identification device, and the access status detection module 190 is specifically configured as follows:
[0065] The access status information is determined based on the pressure value collected by the pressure sensor.
[0066] In this embodiment, the pressure sensor can be installed on the preset identification device access position 110, specifically on the bottom wall inside the storage box 140. When the identification device 120 is stored in the preset identification device access position 110, the pressure sensor can be triggered. Specifically, when the identification device 120 is stored in the preset identification device access position 110, the pressure value collected by the pressure sensor can be greater than 0. When no identification device 120 is stored in the preset identification access position, the pressure value collected by the pressure sensor can be 0. Thus, the access status detection module 190 can determine the access status information based on the pressure value collected by the pressure sensor.
[0067] Furthermore, a standard pressure value can be stored in the storage module 150. When the pressure value detected by the pressure sensor equals the standard pressure value, the marking device 120 is determined to be in a stored state. For example, if the standard pressure value is 1, then when the pressure sensor detects a pressure value of 1, the storage status information is in a stored state; when the pressure sensor detects a pressure value of 0, the storage status information is in a retrieved state. In this way, it is possible to avoid misjudgment caused by the user placing other items of the same color as the marking device 120 into the preset marking device storage position 110 during use.
[0068] In this way, the access status of the marker device 120 at the preset marker device access position 110 can be quickly determined by the pressure sensor. It is simple, fast, low-cost, and easy to maintain later.
[0069] In another embodiment of the present invention, the access status detection module 190 includes a proximity light sensor disposed at the access position 110 of the preset identification device, and the access status detection module 190 is specifically configured as follows:
[0070] The access status information is determined based on the light information detected by the proximity sensor.
[0071] In this embodiment, when the identification device 120 is stored in the preset identification device access position 110, the proximity light sensor can be blocked by the identification device 120. When the identification device 120 is not stored in the preset identification device access position 110, the proximity light sensor will not be blocked. Therefore, the light signal collected by the proximity light sensor will change.
[0072] In this way, the access status of the identification device 120 can be determined based on the light signal detected by the proximity light sensor. The overall structure is simple and the cost is low.
[0073] Furthermore, in one embodiment of the present invention, the processing module 160 is specifically configured as follows:
[0074] When the access status information changes from stored to retrieved, the food information associated with the identifier color information is added to the food storage list; and
[0075] When the access status information changes from the retrieved state to the stored state, the food information associated with the identification color information is deleted from the food storage list.
[0076] In this embodiment, a food storage list of the ingredients stored in the refrigerator 100 can be displayed on the display screen 102 of the refrigerator 100, or the food storage list can be sent to a mobile device such as a user-linked mobile phone via a wireless communication module, so that the user can obtain information about the ingredients stored in the refrigerator 100 without opening the refrigerator door 101. The food storage list may include information such as the name of the ingredients, shelf life, and quantity of the ingredients.
[0077] When the storage status changes from "stored" to "removed," it can be determined that the user has attached the identification device 120 to the food and placed it inside the refrigerator 100 along with the food. This means the user has stored new food inside the refrigerator 100. At this time, the storage module 150 can be queried using the identification color information of the identification device 120 to obtain the associated food information, i.e., the food information stored in the refrigerator 100, and this food information is added to the food storage list. Simultaneously, the removal time of the identification device 120 can be recorded, and the storage time of the corresponding food can be calculated from this removal time. Furthermore, based on the shelf life stored in the storage module 150 or the shelf life entered by the user, it can be determined whether to issue a warning to the user, reminding them to consume the food as soon as possible to avoid waste.
[0078] When the storage status changes from "removed" to "stored," it can be determined that the user has removed food from the refrigerator 100 and removed the attached labeling device 120, placing it back into the preset labeling device storage position 110. At this time, the food information associated with the label color information of the labeling device 120 is the food information removed from the refrigerator 100, and this food information can be deleted from the food storage list. Simultaneously, the time of return of the labeling device 120 can be obtained. Based on the removal and return times, the food storage duration can be determined, and this data is recorded in the historical storage database for user behavior analysis.
[0079] In this way, the food storage list can be managed automatically, making it convenient for users to manage the food in the refrigerator 100.
[0080] Furthermore, the food ingredient management module also includes:
[0081] The door status detection module 170 is configured to detect the opening and closing status of the refrigerator door 101;
[0082] The control module 180 is configured to increase the sampling frequency of the color sensor 130 when the door status detection module 170 detects that the refrigerator 100 door 101 changes from a closed state to an open state, and to decrease the sampling frequency of the color sensor 130 when the door status detection module 170 detects that the refrigerator 100 door 101 changes from an open state to a closed state.
[0083] In this embodiment, the door status detection module 170 can be a magnetic sensor, pressure sensor, or the like installed on the door 101. When the refrigerator door 101 is open, the user may put or take food into the refrigerator 100. Therefore, at this time, the sampling frequency of the color sensor 130 can be increased, or the color sensor 130 can be controlled to collect color information at the preset identification device access position 110 in real time, thereby ensuring timely acquisition of changes in food information inside the refrigerator 100. When the refrigerator door 101 is closed, the possibility of changes in food inside the refrigerator 100 is small. At this time, the sampling frequency of the color sensor 130 can be reduced to reduce energy consumption. Specifically, the color sensor can be controlled to operate at a lower frequency than when the door is open. In this way, if the refrigerator 100 loses power during use, and the user puts or takes food into the refrigerator 100 during the power outage, the food information inside the refrigerator 100 can be acquired in time when the refrigerator is powered on, even if the refrigerator 100 is in the closed state.
[0084] In another embodiment of the present invention, the food ingredient management module further includes:
[0085] The door status detection module 170 is configured to detect the opening and closing status of the refrigerator door 101;
[0086] The control module 180 is configured to control the color sensor 130 to turn on when the door status detection module 170 detects that the refrigerator 100 door 101 changes from a closed state to an open state, and to control the color sensor 130 to turn off when the door status detection module 170 detects that the refrigerator 100 door 101 changes from an open state to a closed state.
[0087] In this embodiment, when the refrigerator door 101 is closed during use, the user cannot retrieve food from the refrigerator 100. Therefore, when the refrigerator door 101 is closed, the color sensor 130 is turned off to reduce energy consumption.
[0088] For a specific example, when a user opens the door 101 of the refrigerator 100, if the user wants to store an egg in the refrigerator 100, they can directly take the identification device 120 with an egg identification mark from the preset identification device access position 110, attach the identification device 120 to the egg, and place it inside the refrigerator 100. If the identification color of the identification device 120 with the egg identification mark is green, when the user takes the identification device 120 with the egg identification mark from the preset identification device access position 110, the pressure value collected by the pressure sensor changes from 1 to 0. At this time, it can be determined that the access state of the identification device 120 changes from the storage state to the retrieval state. When the storage state is obtained, the color information collected by the color sensor 130 is green, that is, the identification color of the identification device 120 is green.
[0089] The processing module 160 automatically queries the food information corresponding to the labeling device 120 based on the labeling color information of the labeling device 120. For example, based on the collected green RGB value, it can find the corresponding food name as eggs, with a shelf life of 15 days, and directly add the egg's food information to the food storage list and display it on the display screen 102. After the user completely removes the eggs from the refrigerator 100, the user will return the labeling device 120 attached to the eggs to the preset labeling device access position 110. If the access status of the labeling device 120 changes from the removed state to the stored state, and the color of the labeling device 120 is green, the processing module 160 queries the storage module 150 to find that the food associated with the green labeling device 120 is eggs, and then deletes the egg's food information from the food storage list.
[0090] The second embodiment of the present invention also provides a food ingredient management module, the food ingredient management module comprising:
[0091] The preset identification device access point 110 has a preset background color;
[0092] The marking device 120 is accessible at the preset marking device access position 110 and has a marking color different from the background color;
[0093] Color sensor 130 is configured to collect color information at the preset identification device access position 110. When the identification device 120 is in the storage state, color sensor 130 collects the identification color information of the identification device 120 stored at the preset identification device access position 110. When the identification device 120 is in the retrieval state, color sensor 130 collects the background color information at the preset identification device access position 110.
[0094] Access status detection module 190 is configured to detect access status information of the identification device 120;
[0095] Storage module 150 is configured to store food information associated with the identification device 120;
[0096] Processing module 160, connected to color sensor 130, access status detection module 190, and storage module 150, is configured to receive access status information and color information collected by color sensor 130; and
[0097] When both the access status information and the color information change, the identification color information and the food information associated with the identification color information are obtained, and the food information associated with the identification color information is managed according to the access status information to generate food storage data.
[0098] In this embodiment, when the access status information changes from the stored state to the retrieved state, and the color information collected by the color sensor 130 changes from the background color information to the identifier color information, it is determined that the identifier device 120 is retrieved from the preset identifier device access position 110. At this time, the food information associated with the identifier color information is the food information placed in the refrigerator 100, and this food information can be added to the food storage list. When the access status information changes from the retrieved state to the stored state, and the color information collected by the color sensor 130 changes from the identifier color information to the background color information, it is determined that the identifier device 120 is placed in the preset identifier device access position 110. At this time, the food information associated with the identifier color information of the identifier device 120 is the food information retrieved from the refrigerator 100, and this food information can be deleted from the food storage list.
[0099] The difference between the food management module of this embodiment and the food management module of the first embodiment of the present invention is that, in this embodiment, by detecting changes in access status information and color information, when changes in access status information and color information are detected simultaneously, it is determined that the identification device 120 is taken out from the preset identification device access position 110 or the identification device 120 is put into the preset identification device access position 110, thereby avoiding identification errors caused by judging from only a single dimension.
[0100] Furthermore, in one embodiment of the present invention, the processing module is configured as follows:
[0101] Obtain the first color information before the color information transformation and the second color information after the color information transformation, and mark the first color information and the second color information that are different from the background color information as the identification color information.
[0102] In this embodiment, when the color information collected by the color sensor 130 changes, the color information that differs from the background color information before and after the change is marked as the identifier color information. Of course, the color information detected by the color sensor 130 when the access status information is in the storage state can also be directly obtained and marked as the identifier color information.
[0103] Furthermore, the food management module can be configured with reference to the first embodiment, such as configuring the storage and retrieval status detection module 190, the processing module 160, the door status detection module 170, the control module 180, etc., which will not be described in detail here.
