[0002] At present, the refrigerator preservation effect test adopts the long-term storage method, among which fruits and vegetables are stored for 10-15 days, and meat products are stored for several months. The refrigerator preservation test indicators include water loss rate, vitamin C, volatile basic nitrogen and juice loss rate. The refrigerator preservation effect test standard mainly involves the test of food nutritional components. The test indicators do not change obviously during the food storage process and cannot truly reflect the food preservation effect. At the same time, since the refrigerator preservation effect test takes a long time, some uncontrollable factors cannot be avoided, and repeatability cannot be guaranteed, resulting in a low accuracy rate of the refrigerator preservation effect test.
[0003] Related art discloses a refrigerator preservation test method, the method comprising: selecting a sample to be tested; the sample to be tested includes multiple food types; measuring a first preservation parameter and a second preservation parameter of the sample to be tested, the first preservation parameter being a parameter when the sample to be tested is stored for a first preset time, and the second preservation parameter being a parameter when the sample to be tested is stored for a second preset time; the first preservation parameter and the second preservation parameter both include at least one of weight, respiration intensity, color characteristic value, and elasticity value; generating freshness data according to the first preservation parameter and the second preservation parameter, the freshness data including at least one of weight loss rate, respiration intensity change rate, color change rate, and elasticity change rate.

[0004] 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:
[0005] Weight loss rate is one of the indicators to measure the preservation effect of fruits and vegetables. Another important indicator related to it and having an important impact on the storage of fruits and vegetables is the amount of condensation. Using relevant technologies based on weight loss rate as an evaluation indicator of the refrigerator's preservation effect cannot cover the scope of fruit and vegetable preservation.

[0045] At present, the refrigerator preservation effect test adopts the long-term storage method, among which fruits and vegetables are stored for 10-15 days, and meat products are stored for several months. The refrigerator preservation test indicators include water loss rate, vitamin C, volatile basic nitrogen and juice loss rate. The refrigerator preservation effect test standard mainly involves the test of food nutritional components. The test indicators do not change obviously during the food storage process and cannot truly reflect the food preservation effect. At the same time, since the refrigerator preservation effect test takes a long time, some uncontrollable factors cannot be avoided, and repeatability cannot be guaranteed, resulting in a low accuracy rate of the refrigerator preservation effect test. The related art discloses a refrigerator preservation test method, the method comprising: selecting a sample to be tested; the sample to be tested includes multiple food types; measuring a first preservation parameter and a second preservation parameter of the sample to be tested, the first preservation parameter being a parameter when the sample to be tested is stored for a first preset time, and the second preservation parameter being a parameter when the sample to be tested is stored for a second preset time; the first preservation parameter and the second preservation parameter both include at least one of weight, respiration intensity, color characteristic value, and elasticity value; generating freshness data according to the first preservation parameter and the second preservation parameter, the freshness data including at least one of weight loss rate, respiration intensity change rate, color change rate, and elasticity change rate. By measuring the first preservation parameter and the second preservation parameter of the sample to be tested, the freshness data of the sample to be tested is obtained to solve the problem of low accuracy of freshness effect detection. Weight loss rate is one of the indicators for measuring the freshness effect of fruits and vegetables, and the important indicator of condensation amount is also related to it and has an important impact on the storage of fruits and vegetables. The use of the related art based on weight loss rate as an evaluation indicator of refrigerator freshness effect cannot cover the scope of fruit and vegetable preservation. However, if the condensation index is included in the scope of the preservation effect test in order to increase the accuracy of the test results, the cost of the test samples may increase.
[0046] The embodiment of the present disclosure discloses a refrigerator, including a processor. The processor is electrically connected to various electrical components and is used to control the various electrical components to perform actions.
[0047] Based on the above refrigerator structure, Figure 1 As shown, the embodiment of the present disclosure provides a method for freshness test, comprising:
[0048] S01, a processor uses a non-woven fabric sheet and deionized water to prepare a first test sample for testing a weight loss rate and a second test sample for a condensation test.
[0049] S02, the processor tests the weight loss rate of the refrigerator and the condensation size of the test drawer according to the first test sample and the second test sample respectively.
[0050] S03, the processor determines the preservation effect of the refrigerator according to the weight loss rate of the refrigerator and the condensation size of the test drawer.
[0051] The method for freshness-keeping test provided by the embodiment of the present disclosure is adopted, and a first test sample for testing weight loss rate and a second test sample for condensation test are prepared by using a non-woven fabric sheet and deionized water. The weight loss rate of the refrigerator and the condensation size of the test drawer are tested according to the first test sample and the second test sample, respectively. According to the weight loss rate of the refrigerator and the condensation size of the test drawer, the freshness-keeping effect of the refrigerator is determined. By using a non-woven fabric sheet and deionized water to prepare a sample compatible with the weight loss rate test and the condensation test, the condensation amount index is incorporated into the refrigerator freshness-keeping effect test to test the accuracy of the test results, while reducing the cost of the test.
[0052] Alternatively, if Figure 2 As shown, the processor uses a non-woven fabric sheet and deionized water to prepare a first test sample for testing weight loss rate, including:
[0053] S21, the processor places a first number and a first size of non-woven fabric sheets in a first type of tray.
[0054] S22, the processor injects a third weight of deionized water into the tray to obtain a first test sample.
[0055] In this way, the processor places the non-woven fabric sheets of the first quantity and the first size in the first type of tray, and injects the third weight of deionized water into the tray to obtain a first test sample. The first test sample for weight loss rate test is prepared by using the non-woven fabric sheets and deionized water, which simplifies the preparation of the sample, reduces the cost of the test, and realizes the standardization of the test samples, ensuring the objectivity, repeatability and reproducibility of the data.
[0056] Alternatively, if Figure 3 As shown, the processor uses a non-woven fabric sheet and deionized water to prepare a second test sample for condensation testing, including:
[0057] S31, the processor places a second number and a second size of non-woven fabric sheets in a second type of tray.
[0058] S32, the processor injects a fourth weight of deionized water into the tray and leaves it to stand for a fourth period of time to obtain a second test sample.
[0059] In this way, the processor places the second number and the second size of non-woven fabric sheets in the second type of tray, injects the fourth weight of deionized water into the tray and leaves it for a fourth time to obtain a second test sample. The second test sample for condensation testing is made by using non-woven fabric sheets and deionized water, which simplifies the sample preparation, reduces the test cost, and realizes the standardization of the test samples, ensuring the objectivity, repeatability and reproducibility of the data.
[0060] As an example, 18 non-woven fabric sheets of 75 mm × 125 mm in size can be placed in a test tray, and 600 g ± 50 g of deionized water can be injected into the tray to prepare a first test sample. Six dry non-woven fabric sheets can be placed in a type B test tray, and 200 g ± 50 of deionized water can be injected into the tray and left to stand for 10 minutes to prepare a second test sample.
[0061] Based on the above refrigerator structure, Figure 4 As shown, the embodiment of the present disclosure provides a method for freshness test, comprising:
[0062] S01, a processor uses a non-woven fabric sheet and deionized water to prepare a first test sample for testing a weight loss rate and a second test sample for a condensation test.
[0063] S02, the processor tests the weight loss rate of the refrigerator and the condensation size of the test drawer according to the first test sample and the second test sample respectively.
[0064] S41: The processor determines a weight loss score of the refrigerator according to the weight loss rate of the refrigerator.
[0065] S42: The processor determines a condensation score of the refrigerator according to the condensation size of the test drawer.
[0066] S43: The processor determines the freshness preservation effect of the refrigerator according to the weight loss score and the condensation score.
[0067] Using the method for freshness-keeping test provided by the embodiment of the present disclosure, the processor determines the weight loss score of the refrigerator according to the weight loss rate of the refrigerator, and determines the condensation score of the refrigerator according to the condensation size of the test drawer. Finally, the processor determines the freshness-keeping effect of the refrigerator based on the weight loss score and the condensation score. Based on the weight loss rate of the test sample and the condensation size of the test drawer, the freshness-keeping effect of the refrigerator is comprehensively determined and scored, so that the freshness-keeping test effect is visualized, allowing developers or users to more clearly understand the freshness-keeping performance of the refrigerator. Incorporating the condensation amount index into the refrigerator freshness-keeping effect test fully considers the impact of condensation on the freshness-keeping of fruits and vegetables, covers the freshness-keeping scope of fruits and vegetables, and improves the accuracy of the refrigerator freshness-keeping effect test.
[0068] Optionally, the processor obtains the weight loss rate of the test sample, including: when the first test sample is placed in the fresh-keeping compartment of the refrigerator, the processor obtains the placement time of the first test sample; when the placement time reaches the first time, the processor records the first weight of the test sample; when the placement time reaches the second time, the processor records the second weight of the test sample; the processor calculates W = [(M1-M2) / (t2-t1)]×24; wherein W is the weight loss rate of the test sample, M1 is the first weight, M2 is the second weight, t1 is the time of recording the first weight, and t2 is the time of recording the second weight.
[0069] Among them, the unit of W is g / 24h, the unit of M1 and M2 is g, the unit of t1 and t2 is h, t2-t1≥24h, M1-M2≤200g.
[0070] Among them, the first duration and the second duration can be any time length. Since different test samples may be made of different materials, and the test environment parameters will also affect the stability of the test samples, for example, the materials of some test samples include non-woven fabrics and deionized water, and the materials of some test samples include gelatin and glycerol, etc., and the temperature and / or humidity of the test environment will affect the stability time of the above different test samples. Therefore, the first duration can be specifically determined according to the type of the first test sample and / or the test environment parameters, for example, by table lookup method or experience, so that the first test sample can reach a stable state after being placed for the first time. The second duration is the time length of the weight loss rate test. Similarly, since the test samples of different materials have different weight loss times under different test environment parameters, the second duration can be specifically determined according to the type of the first test sample and / or the test environment parameters, for example, by table lookup method or experience, so that when the second duration is reached, the weight loss phenomenon can be more obvious, so that the weight loss rate test result of the first test sample is more accurate.
[0071] In this way, when the first test sample is placed in the fresh-keeping room of the refrigerator, the processor obtains the placement time of the first test sample. When the placement time reaches the first time, the state of the first test sample in the fresh-keeping room of the refrigerator has stabilized, so the processor records the first weight of the test sample. When the placement time reaches the second time, the deadline for the weight loss rate test has been reached, so the processor records the second weight of the test sample. Finally, the processor substitutes the first weight and the second weight into the calculation formula W = [(M1-M2) / (t2-t1)]×24 for calculation, and obtains the weight loss rate of the first test sample in the fresh-keeping room of the refrigerator for 24 hours.
[0072] Optionally, the processor obtains the condensation size of the test drawer, including: the processor divides each side of the test drawer of the refrigerator into test areas; when a set number of second test samples are placed in the test drawer, the processor obtains the placement time of the second test samples; when the placement time reaches a third time, the processor detects the condensation size of each test area.
[0073] The third duration may be any duration, for example, 48 hours, 72 hours, and 96 hours.
[0074] The processor divides each side of the test drawer of the refrigerator into test areas, and specifically can divide the test drawer into squares according to the size of each side. The size of the square can be determined according to the set test parameters, including the temperature, humidity, volume of the test drawer, fan speed, operating frequency of the compressor and / or the relative position of the test drawer and the fan during the test, etc. The size of the square can be determined by looking up a table or introducing expert experience. For example, if the size of the square is 50mm×50mm, the length of the long side of each side of the test drawer is L1(mm) / 50mm, that is, the number of grids on the long side is m (if there is a remainder, the number of grids is increased by 1), and the length of the wide side is W1(mm) / 50mm, that is, the number of grids on the wide side is n (if there is a remainder, the number of grids is increased by 1), and the product of m and n is the number of grids on each side.
[0075] Among them, since the time when condensation occurs in the test drawer is different for test samples of different materials under different test environment parameters, the third time duration can be determined specifically according to the type of the second test sample and / or the test environment parameters, for example, by table lookup or experience, so that when the third time duration is reached, the condensation phenomenon in the test drawer can be more obvious, thereby making the condensation test result of the second test sample more accurate.
[0076] In this way, the processor divides each surface of the test drawer of the refrigerator into test areas, so that the condensation condition of the entire test drawer can be determined from the condensation size in each test area. When a set number of second test samples are placed in the test drawer, the processor obtains the placement time of the second test samples. When the placement time reaches the third time, the deadline for the condensation test is reached. Therefore, the processor detects the condensation size of each test area to obtain the condensation condition of the refrigerator test drawer.
[0077] Optionally, the processor determines the set number in the following manner: the processor determines the set number according to the volume of the test drawer.
[0078] In this way, the processor determines the set quantity according to the volume of the test drawer, so that the second test sample can match the volume of the test drawer, thereby simulating the actual storage conditions of fresh vegetables and making the results of the preservation test more accurate.
[0079] Optionally, the processor determines the set quantity based on the volume of the test drawer, including: the processor obtains the volume of the test drawer; the processor calculates S1=L / 3; the processor processes the calculation result according to the rounding method to obtain the set quantity; wherein S1 is the theoretical number of the second test samples, and L is the volume of the test drawer.
[0080] In this way, the processor obtains the volume of the test drawer and calculates S1=L / 3. Finally, the calculation result is rounded off to get the set number. By covering one third of the test drawer with the second test sample, the second test sample can be matched with the volume of the test drawer, thereby simulating the actual storage conditions of fresh vegetables and making the results of the preservation test more accurate.
[0081] Optionally, the processor determines the weight loss score of the refrigerator according to the weight loss rate of the refrigerator, including: the processor determines, according to the first relationship, a first score corresponding to the weight loss rate as the weight loss score.
[0082] In this way, the processor determines the first score corresponding to the weight loss rate as the weight loss score according to the first relationship, so that the weight loss score can be matched with the weight loss rate, thereby improving the accuracy of the freshness test.
[0083] Optionally, the processor determines the condensation score of the refrigerator based on the condensation size of the test drawer, including: the processor determines the condensation score corresponding to the condensation size of each test area based on a preset correspondence; the processor calculates the average value of the condensation scores of the test areas; the processor determines a second score corresponding to the average value based on a second relationship.
[0084] Among them, the processor determines the condensation score corresponding to the condensation size of each test area according to a preset corresponding relationship. The preset relationship can be: water mist and no condensation get 0 points; water droplets with condensation size less than 10mm get 1 point; flowing water gets 2 points; accumulated water with condensation size greater than 10mm gets 3 points.
[0085] In this way, the processor can determine the condensation situation of each test area from the condensation scores of each test area, and the processor calculates the average of the condensation scores of the test areas, thereby determining the condensation situation of the entire test drawer. Finally, the processor determines a second score corresponding to the average value based on the second relationship, so that the second score can match the condensation situation of the refrigerator, thereby improving the accuracy of the freshness preservation effect test.
[0086] Optionally, as an example, the first relationship and the second relationship may refer to Table 1.
[0087] Table 1
[0088]
[0089]
[0090] Optionally, the method for freshness-keeping testing further includes: the processor marking the freshness-keeping effect of the refrigerator.
[0091] The processor identifies the freshness-keeping effect of the refrigerator, which may be specifically: the processor controls the refrigerator to display a first score and a second score.
[0092] In this way, by controlling the refrigerator to display the first score of the weight loss rate and the second score of the condensation, users and testers can more clearly determine the preservation effect of the refrigerator in the dual dimensions of weight loss rate and condensation.
[0093] Optionally, the method for freshness testing further includes: the processor determining an improvement strategy based on the first score and the second score.
[0094] In this way, the processor determines the improvement strategy according to the first score and the second score, so that the developer can improve the refrigerator in a targeted manner based on the defects of the refrigerator, thereby further improving the freshness preservation effect of the refrigerator.
[0095] Optionally, the processor determines an improvement strategy based on the first score and the second score, including: the processor determines defects in the refrigerator based on the first score and the second score; the processor proposes an improvement strategy based on the defects in the refrigerator.
[0096] In this way, the processor determines the defects of the refrigerator based on the first score and the second score, and proposes improvement strategies based on the defects of the refrigerator, so that developers can improve the refrigerator in a targeted manner based on the defects of the refrigerator and improve development efficiency. For example, if the first score is 2 points and the second score is 5 points, it means that the weight loss is heavy, but the condensation is very light, and the preservation effect is medium to low, and the sealing or air supply characteristics of the drawer may need to be improved; if the first score is 4 points and the second score is 5 points, it means that the weight loss is light, the condensation is very light, and the preservation effect is good.
[0097] Optionally, the processor determines the freshness preservation effect of the refrigerator according to the first score and the second score, including: the processor calculates S=Y-0.2×e 0.24x ; Wherein, S is the refrigerator's preservation effect score, Y is the first score as the weight loss score, and X is the second score as the condensation score.
[0098] Thus, the processor calculates S = Y - 0.2 × e 0.24x By using the above calculation formula and taking the calculation result as the refrigerator's fresh-keeping effect score, the proportion of weight loss rate and condensation in the refrigerator's fresh-keeping effect test can be more accurately allocated, thereby improving the accuracy of the refrigerator's fresh-keeping effect test.
[0099] Combination Figure 5As shown, an embodiment of the present disclosure provides a device 800 for freshness test, including a processor 801 and a memory 802. Optionally, the device may also include a communication interface 803 and a bus 804. The processor 801, the communication interface 803, and the memory 802 may communicate with each other through the bus 804. The communication interface 803 may be used for information transmission. The processor 801 may call the logic instructions in the memory 802 to execute the method for freshness test of the above embodiment.
[0100] In addition, the logic instructions in the memory 802 described above may be implemented in the form of software functional units and when sold or used as independent products, may be stored in a computer-readable storage medium.
