The interval length setting of the temperature variation value range may be obtained by averaging the maximum temperature variation value range of the refrigerating compartment 120 of the refrigerator 100. Similarly, the interval length setting of the humidity variation range may be evenly divided according to the maximum humidity variation range of the refrigerating compartment 120 of the refrigerator 100. For example, the temperature of the storage compartment ranges from 1 ℃ to 9 ℃ and the humidity ranges from 30% RH to 80% RH. Correspondingly, the temperature change value range of the storage chamber is-8 ℃, and the humidity change value range of the storage chamber is-50% RH-50% RH. The temperature variation numerical range is divided into 10 equal parts, and n is 10; the humidity change value range is divided into 10 equal parts, and m is 10. For another example, the temperature variation value range is divided into 20 equal parts, and n is 20; the humidity change value range is divided into 10 equal parts, and m is 10.
The reference coefficient Xnm may be determined by ensuring air inside the test chamber to be clean, adjusting different humidity change values, and measuring changes in the odor detection value of the odor sensor 300 before and after each change in the test chamber in which the temperature change value is maintained. Or in a test chamber in which the humidity change value is kept unchanged, the air inside the test chamber is ensured to be clean, different temperature change values are adjusted, and the change of the odor detection value of the odor sensor 300 before and after each change is measured, so as to confirm the reference coefficient. For example, the temperature variation value is always 1 ℃, and the humidity variation values are respectively controlled to be 5% RH, 10% RH, and 50% RH, so as to obtain different reference coefficients Xnm. Then, the temperature change value is set to be 5 ℃ all the time, and the humidity change values are controlled to be 5% RH, 10% RH, and 50% RH respectively, so as to obtain different reference coefficients Xnm.
In other embodiments, in the method for compensating for the smell parameter of the refrigerator 100 of the present invention, the step of acquiring the pre-stored reference coefficient includes:

Generally, the temperature of the refrigerating compartment 120 in the previous test cycle is taken as the second temperature, and the humidity of the refrigerating compartment 120 in the previous test cycle is taken as the second humidity, so that the data are kept coherent before and after. In the method for compensating the odor parameter of the refrigerator 100 according to the embodiment, the reference coefficient is determined by using the preset second mapping relationship based on the temperature and humidity of the refrigerating compartment 120 in the current detection period and the change values of the temperature and humidity of the refrigerating compartment 120 in the two detection periods, the influence of the temperature, humidity and temperature and humidity of the refrigerating compartment 120 on the odor sensor 300 is fully considered, and the reference coefficient is determined by using the preset second mapping relationship, so that the processing efficiency of the controller 401 of the refrigerator 100 can be improved, and the reference coefficient can be determined timely, quickly and accurately. This embodiment also takes into account the current state of the cold storage compartment 120, as compared to the previous embodiment where the reference coefficient is determined based on the change values of temperature and humidity. For example, the temperature is changed by 1 ℃ and the humidity is changed by 10% RH. The compensation method of this embodiment distinguishes between the reference coefficient corresponding to the first temperature of 5 ℃, the first humidity of 40% RH, the second temperature of 4 ℃, and the second humidity of 30% RH, and the reference coefficient corresponding to the first temperature of 9 ℃, the first humidity of 70% RH, the second temperature of 8 ℃, and the second humidity of 60% RH.

Similarly, the interval length setting of the humidity variation range may be evenly divided according to the maximum humidity variation range of the refrigerating compartment 120 of the refrigerator 100. For example, the first temperature value of the storage compartment ranges from 1 ℃ to 9 ℃ and the first humidity value ranges from 30% RH to 80% RH. Correspondingly, the temperature change value range of the storage chamber is-8 ℃, and the humidity change value range of the storage chamber is-50% RH-50% RH.
