Detailed ways

The present invention first provides a control method for a refrigerator having a food material management module for managing food materials placed therein. That is to say, the control method of the present invention is suitable for smart refrigerators with food management functions.

Figure 1 is a schematic flow chart of a control method for a refrigerator according to an embodiment of the present invention. Referring to Figure 1, the control method of the present invention includes:

Step S10, when new food is put into the refrigerator, a pesticide residue detection prompt message is sent; the pesticide residue detection prompt message is used to remind the user to perform a pesticide residue test on the newly placed food;

Step S20, obtain the pesticide residue detection result of the newly put food; the pesticide residue detection result is the result of the refrigerator or the pesticide residue detection equipment associated with the refrigerator responding to the pesticide residue detection start instruction triggered by the user according to the pesticide residue detection prompt information. The test results obtained after the food ingredients are tested for pesticide residues; and

Step S30: Record the pesticide residue detection results in the food material information of the newly added food.

That is to say, every time it detects that new food is put into the refrigerator, the refrigerator will automatically send out a pesticide residue detection prompt message to automatically remind the user to conduct a pesticide residue test on the newly added food, which is conducive to timely and comprehensive collection of pesticide residues. Pesticide residue information on all ingredients placed in the refrigerator. When the user starts pesticide residue detection through a refrigerator with pesticide residue detection function or other pesticide residue detection equipment associated with the refrigerator, the refrigerator or other detection equipment outputs the pesticide residue detection results, and the refrigerator obtains the pesticide residue detection results of the newly placed ingredients. Record it into the ingredient information of the newly added ingredients, so that the ingredient management module can conduct more reasonable ingredient management based on the pesticide residues of each ingredient and other ingredient information, which can not only make the user's diet healthier, but also improve the efficiency of the refrigerator. The degree of intelligence improves the user experience.

In some embodiments, the refrigerator also has a pesticide residue detection module for detecting pesticide residues on samples. In these embodiments, the pesticide residue detection prompt information is used to remind the user to sample the newly placed food ingredients and put them into the sample cup of the pesticide residue detection module so that the newly added food ingredients can be tested for pesticide residues through the pesticide residue detection module. In other words, when the refrigerator itself is integrated with a pesticide residue detection module, it can directly remind the user to put the newly added food samples into the sample cup of the pesticide residue detection module, which is more direct and clear, and can be done in one step.

Further, the pesticide residue detection start instruction is triggered and generated after detecting that a sample is placed in the sample cup of the pesticide residue detection module. That is to say, when the user puts the sample into the sample cup, the pesticide residue detection start command is triggered.

Further, the pesticide residue detection result is the detection result obtained after the pesticide residue detection module automatically detects the sample in the sample cup according to the pesticide residue detection start instruction. That is to say, the pesticide residue detection result can automatically start the detection program in response to the pesticide residue detection start instruction.

The refrigerator in a further embodiment of the present invention is integrated with a pesticide residue detection module. When new food ingredients are put into the refrigerator, the pesticide residue prompt information sent by the refrigerator can remind the user to sample the newly placed food ingredients and put them into the sample cup of the pesticide residue detection module. In order to detect pesticide residues in newly added food through the refrigerator's own pesticide detection module. When the user puts the newly added food sample into the sample cup, it can directly trigger the pesticide residue detection start command. The pesticide residue detection module can automatically detect pesticide residues on the sample in the sample cup. After the detection is completed, the pesticide residue detection result obtained Test results can be recorded and saved directly. During the entire process, users only need to take samples and participate in very few operations, which improves the user's convenience in using the refrigerator and further improves the automation and intelligence of the refrigerator.

Specifically, FIG. 2 is a schematic flow chart of a control method of a refrigerator according to another embodiment of the present invention. Referring to Figure 2, the control method of the present invention includes:

Step S10, when new food is put into the refrigerator, a pesticide residue detection prompt message is issued; the pesticide residue detection prompt message is used to remind the user to sample the newly placed food and put it into the sample cup of the pesticide residue detection module so that it can be passed through the pesticide residue detection module. The residue detection module detects pesticide residues in newly added food materials;

Step S21, determine whether there is a sample placed in the sample cup of the pesticide residue detection module; if so, go to step S22; if not, return to continue the judgment;

Step S22, automatically detect pesticide residues on the sample in the sample cup through the pesticide residue detection module;

Step S23, when the pesticide residue detection module completes the detection, the pesticide residue detection result is output; and

That is to say, the step S20 of obtaining the pesticide residue detection result of the newly added food may specifically include the above-mentioned steps S21 to S23. Specifically, step S21 can be implemented by changing the weight in the sample cup before and after placing the sample. When the weight in the sample cup increases, it can be determined that a sample is placed in the sample cup.

Figure 3 is a schematic flow chart of automatically detecting pesticide residues on samples in a sample cup through a pesticide residue detection module according to an embodiment of the present invention. In some embodiments, the step S22 of automatically detecting pesticide residues on the sample in the sample cup through the pesticide residue detection module may specifically include:

Step S221: Weigh the sample cup in response to the pesticide residue detection start command to obtain the weight of the sample in the sample cup;

Step S222, input a corresponding amount of buffer into the sample cup according to the weight of the sample in the sample cup;

Step S223, suspend the sample cup and then oscillate the sample cup to obtain the sample liquid; and

Step S224, use the enzyme inhibition method to detect the obtained sample liquid, thereby obtaining the pesticide residue detection result of the newly added food.

Specifically, the weight of the sample in the sample cup can be obtained through the weighing unit of the pesticide residue detection module. After obtaining the weight of the sample, the amount of buffer required can be calculated and injected into the sample cup. That is to say, the amount of buffer corresponds to the weight of the sample to obtain a sample solution of appropriate concentration. After injecting the sample solution into the sample cup, the sample cup needs to be shaken appropriately to fully mix the pesticide residues on the sample with the buffer, thereby improving the accuracy of the test results. In order to prevent the oscillation of the sample cup from adversely affecting the performance of the weighing unit, in step S223, the sample cup is suspended in the air to separate from the weighing unit before oscillating, thereby avoiding the oscillation force acting on the weighing unit, thereby effectively avoiding oscillation. Effects of operation on the weighing unit. In step S224, the principle that pesticides inhibit the activity of enzymes can first be used to react the residual pesticides in the sample solution with the enzyme reagents, and then a light transmission test is performed on the reacted solution, which facilitates the determination of absorbance through the light intensity signal received by the photosensitive element. changes, and then obtain the pesticide residue detection results. Since the detection of pesticide residues using the enzyme inhibition method is a technology relatively easily available to those skilled in the art, it will not be described in detail here.

In some embodiments, before obtaining the pesticide residue detection results of newly added food materials, the control method of the present invention further includes:

The ingredient information of the newly placed ingredients is obtained through the ingredient management module and saved; the ingredient information at least includes the names of the ingredients of the newly added ingredients.

In other words, the ingredient information of the ingredients newly placed in the refrigerator can be automatically obtained through the ingredient management module of the refrigerator, without the need for manual input by the user, and the level of intelligence is high.

Specifically, there are many ways for the ingredient management module to obtain ingredient information of newly added ingredients. For example, QR code recognition and image recognition that are commonly used in the prior art, as well as the cooperation between the antenna board and the food management clip previously proposed by the applicant, etc., will not be described in detail here.

In other embodiments, before obtaining the pesticide residue detection results of newly added food materials, the control method of the present invention further includes:

Receive and save the ingredient information of the newly added ingredients input by the user; the ingredient information at least includes the names of the ingredients of the newly added ingredients.

In other words, the ingredient information of the ingredients newly put into the refrigerator can be manually input by the user. The manually input ingredient information is more accurate, ensuring that the correspondence between the ingredient information and the newly added ingredients is highly consistent.

Specifically, the above-mentioned food material information may further include information closely related to the food materials such as the purchase time of the newly added food materials and shelf life information.

It can be understood that the step of obtaining the ingredient information of the newly added ingredients or receiving and saving the ingredient information of the newly added ingredients can be performed before the pesticide residue detection prompt information is issued, or after the pesticide residue detection prompt information is issued. Preferably, when the refrigerator detects that new ingredients are put in, it first automatically obtains the ingredient information of the newly put ingredients, and then issues a pesticide residue detection prompt message.

In some embodiments, after recording the pesticide residue detection results into the food material information of the newly placed food materials, the control method of the present invention further includes:

Display the pesticide residue test results to the user through the display screen of the refrigerator; and/or

The pesticide residue detection results are broadcast through the voice broadcast module of the refrigerator.

That is to say, the present invention also outputs the pesticide residue detection results to the user through display screen display and/or voice broadcast, so that the user can clearly know the pesticide residue status of the newly added food.

In some embodiments, after outputting the pesticide residue detection results to the user, the control method of the present invention further includes:

Issue a test result correction prompt message; the test result correction prompt message is used to remind the user whether the correspondence between the currently displayed pesticide residue test results and the newly added food ingredient information recorded in the refrigerator needs to be corrected;

If the confirmation correction instruction input by the user is received within the preset time period; receive the corrected ingredient information input by the user; store the corrected ingredient information corresponding to the pesticide residue test results;

If no confirmation correction instruction input by the user is received within the preset time period or a denial correction instruction input by the user is received, the pesticide residue detection results will be stored in correspondence with the ingredient information of the newly added ingredients recorded in the refrigerator.

It is understandable that information about newly added ingredients is usually automatically identified and obtained through the ingredient management module of the refrigerator, and the results may have certain deviations or even errors. At the same time, the object of pesticide residue testing is the sample that the user manually takes and puts into the sample cup. There may also be uncertainty as to whether the sample is taken from the food material again. Therefore, after the present invention outputs the pesticide residue detection results to the user, it sends a detection result correction prompt message to remind the user to confirm whether the pesticide residue detection results output by the pesticide residue detection module correspond to the food material information of the sample. The user can confirm again. Ensure the accurate correspondence between pesticide residue test results and food ingredient information, making it easier to make more accurate and reasonable food material management plans.

Specifically, if the user needs to correct the correspondence between the pesticide residue test results and the food ingredient information, feedback will be given within a preset time after the test result correction prompt message is sent to form a confirmation correction instruction. After that, the corrected information input by the user can be accepted. of food ingredients information, and then save the corrected food ingredients information in correspondence with the pesticide residue test results. If the user does not need to correct the correspondence between pesticide residue test results and food ingredient information, the user may not feedback any information within the preset time period after the test result correction prompt message is sent, or may enter a denial of correction instruction, then directly Just save the pesticide residue test results in correspondence with the food information of the newly added food recorded in the refrigerator.

Specifically, FIG. 4 is a schematic flow chart of a control method of a refrigerator according to yet another embodiment of the present invention. Referring to Figure 4, the control method of the present invention includes:

Step S10, when new ingredients are put into the refrigerator, a pesticide residue detection prompt message is sent;

Step S20, obtain the pesticide residue detection results of the newly added food materials;

Step S30, record the pesticide residue detection results into the food material information of the newly added food materials;

Step S40, display the pesticide residue detection results to the user through the display screen of the refrigerator and/or broadcast the pesticide residue detection results through the voice broadcast module of the refrigerator;

Step S50: Send a detection result correction prompt message;

Step S60: Whether the confirmation correction instruction input by the user is received within the preset time period; if so, go to step S70; if not, go to step S90;

Step S70: Receive the corrected ingredient information input by the user;

Step S80, save the corrected food material information and the pesticide residue detection results in correspondence;

Step S90: Correspondingly store the pesticide residue detection results and the food material information of the newly added food recorded in the refrigerator.

Consumption recommendation information is generated and output based on the pesticide residue detection results; the consumption recommendation information may include information for recommending users to eat directly, information for recommending users to eat after removing pesticide residues, and information for recommending users to avoid eating.

Specifically, the pesticide residue detection results accurately reflect the pesticide residues of the food. When the pesticide residues are serious, the user can be reminded to avoid eating them; when the pesticide residues are average, the user can be reminded to remove the pesticide residues before eating; when the pesticide residues meet the When required for consumption, users can be reminded to eat directly without removing pesticide residues. There are many ways to express pesticide residue test results, and users may not be able to accurately identify them, or the way that allows users to accurately identify pesticide residue test results is complicated. Therefore, the present invention outputs consumption suggestions based on the pesticide residue detection results, which facilitates users to more intuitively understand the pesticide residues of food materials, and determines the consumption method based on the suggestions, thereby improving the user experience.

In some embodiments, the control method of the present invention further includes: detecting whether new food ingredients are put into the refrigerator.

Specifically, there are many ways to detect whether new ingredients have been put into the refrigerator. For example, after detecting the door closing signal of the refrigerator, the radio frequency identification REID tag corresponding to each food item in each room of the refrigerator can be detected to obtain the first food identification set; according to the first food identification set and the second food identification set The comparison results determine whether there are new ingredients in the refrigerator. The second ingredient identification set is a set of ingredient identifications obtained when the refrigerator door was closed last time. For another example, you can directly compare the images of each room taken before and after the refrigerator door is opened to determine whether there are new ingredients put into the refrigerator. For another example, when the refrigerator door is opened, the antenna board scans the food folders with specific chips at the predetermined position to obtain the first information set. After the door is closed, the antenna board scans the food folders at the predetermined position to obtain the second information set. Comparison of the first information set and the second information set determines whether new ingredients are put into the refrigerator.

Since there are many ways to detect whether new food ingredients are put into the refrigerator, and the techniques are easily available to those skilled in the art, they will not be described in detail here.

After the residue detection results are recorded, they will be recorded into the ingredient information of the newly added ingredients, so that the ingredient management module can conduct more reasonable ingredient management based on the pesticide residue status of each ingredient and other ingredient information, which can not only make the user's diet healthier, but also The degree of intelligence of the refrigerator 1 is improved and the user experience is improved.

Furthermore, the refrigerator 1 also has a pesticide residue detection module 30 for detecting pesticide residues on samples. When new food ingredients are put into the refrigerator 1, the pesticide residue prompt message sent by the refrigerator 1 can remind the user to take a sample of the newly added food ingredients and put them into the sample cup of the pesticide residue detection module 30, so that they can be passed through the pesticide residue detection module 30 of the refrigerator 1 itself. Conduct pesticide residue testing on newly added food. When the user puts the newly added food sample into the sample cup, the pesticide residue detection module can automatically detect pesticide residues on the sample in the sample cup.
