In step S103, when the storage space stores an edible material, the humidity of the storage space is controlled to an optimal storage humidity value of the food material.

At this time, since only one food material is stored in the storage space, it is only necessary to consider the optimal storage humidity value of the food material, and the optimal storage humidity value of the food material can be selected from the optimal storage humidity range of the food material, preferably The intermediate value of the optimal storage humidity range.

In step S104, when the storage space stores a plurality of food materials, the humidity of the storage space is controlled according to an optimal storage humidity value of each of the plurality of food materials.

At this time, it is necessary to comprehensively consider the humidity environment to which various ingredients are adapted, in order to determine the humidity which enables the mixed foods to achieve the best fresh-keeping effect as a whole.

2 is a flow chart of a method of controlling the humidity of a storage space of a refrigerator in accordance with another embodiment of the present invention. In FIG. 2, steps S201-S203 are the same as steps S101-S103, respectively, and details are not described herein again.

As shown in FIG. 2, the method may also preferably include the following steps:

In step S204, an optimal stored humidity value of each of the ingredients is determined.

In step S205, the maximum value and the minimum value are determined from the optimal stored humidity values of the plurality of food materials.

In step S206, it is determined whether the maximum value is equal to the minimum value.

In step S207, when the maximum value is equal to the minimum value, the humidity of the storage space is controlled to the maximum value or the minimum value.

If the maximum value is equal to the minimum value, the type of the food in the storage space is different, but the various food materials have the same humidity environment and belong to a similar type of food. Therefore, the humidity of the storage space can be controlled to The maximum or the minimum, thereby providing an optimal humidity storage environment for all of the ingredients.

In step S208, when the maximum value is not equal to the minimum value, the humidity of the storage space is controlled according to the maximum value, the minimum value, and the preset humidity. At this time, the humidity environment adapted to the various food materials stored in the storage space is different, and the maximum value and the minimum value need to be further comprehensively considered, and the preset humidity is introduced to control the humidity in the storage space of the refrigerator.

3 is a flow chart of a method of controlling the humidity of a storage space of a refrigerator in accordance with another embodiment of the present invention. In FIG. 3, steps S301-S307 are the same as steps S201-S207 described above, and therefore will not be described again.

As shown in FIG. 3, the method may preferably include the following steps:

Wherein, in steps S308 and S310, the maximum value and the minimum value are compared with the preset humidity. It is determined in step S308 whether the preset humidity is greater than the maximum value, and if not, it is further determined in step S310 whether the preset humidity is less than the minimum value.

In step S309, when the maximum value is less than the preset humidity, the humidity of the storage space is controlled to a low gear humidity.

In step S311, when the minimum value is greater than the preset humidity, the humidity of the storage space is controlled to a high-grade position humidity.

In step S312, when the preset humidity is between the minimum value and the maximum value, The humidity of the storage space is controlled to the preset humidity.

Assuming that the preset humidity is H, the range of H is 0% RH < H < 100% RH, and the maximum value is assumed to be Hmax, and the minimum value is Hmin. The humidity of the storage space can be divided into three gear positions: high-grade humidity HU, HU value can be between H and 100% RH, suitable for fruits and vegetables, etc.; low-grade humidity HL, HL can be Between 0%RH and H, suitable for dry foods that are easy to absorb moisture and mold; intermediate gear H, when the average humidity in the storage space is controlled in the middle gear position H, it is suitable for some non-volatile water roots and some foods and some Cooked food, etc., and can also take care of wet ingredients or dry ingredients.

In the case of Hmax≠Hmin, it is first determined whether Hmax is less than the preset humidity H. If it is less than, the humidity environment adapted to all the ingredients is in the low-range humidity, and it is determined that the current space humidity is controlled to the low-humidity position HL; If it is less than then, it is judged whether Hmin is greater than the preset humidity H. If it is greater than that, the humidity environment adapted to all the ingredients is in the high-grade humidity HU, and it is determined that the humidity in the current space is controlled as the high-grade humidity HU; if Hmin≤H≤Hmax It means that the ingredients in the current space have wet ingredients and dry ingredients. It can be determined that the current space humidity is controlled in the middle humidity position H to take into account the preservation effect of all ingredients.

The preset humidity H preferably ranges from 60% to 75% RH.

In other embodiments, when the low gear humidity is preferably less than the preset humidity, the high gear humidity is preferably greater than the preset humidity.

Wherein, the optimal storage humidity value of the foodstuff is preferably an intermediate value of the optimal storage humidity range of the foodstuff. To illustrate this, the optimal storage humidity range for some of the ingredients is exemplarily listed in Table 1. For each ingredient, there is an optimal moisture storage range that is conducive to the preservation of the ingredients. For example, the optimal humidity range for nuts is 65-75% RH, and the optimal storage humidity for dry pulp is 50- 60% RH, the median value of the best storage humidity range for each ingredient can be selected as its optimal storage humidity value. For example, the best stored moisture value for nuts is 67.5% RH and the dried pulp is 55% RH.

Table 1:

When a plurality of food materials as shown in Table 1 are mixed in the storage space of the refrigerator, the maximum value is 97.5% RH, and the minimum value is 40% RH, assuming that the preset humidity value is 65% RH at this time, 40% RH<65%RH<97.5%RH, indicating that the humidity environment of the various food materials stored in the storage space is humid and humid, and the humidity of the storage space is preferably controlled to be preset. Humidity 65% RH.

When only dry pulp and milk chocolate are stored in the refrigerator, the maximum value is 55% RH, the minimum value is 40% RH, 55% RH < 65% RH, and the maximum value is less than the preset humidity, so The humidity of the storage space is controlled to a low gear humidity. At this time, the low gear humidity may be an intermediate value between the maximum value and the minimum value, and may also preferably be the minimum value, that is, 40% RH.

When the zucchini, potatoes and canola are stored in the refrigerator, the maximum value is 97.5% RH, the minimum value is 72.5% RH, 65% RH < 72.5% RH, and the minimum value is greater than the preset humidity, so The humidity of the storage space is controlled to a high-grade humidity. At this time, the high-grade humidity may be an intermediate value between the maximum value and the minimum value, and may also preferably be the maximum value, that is, 97.5%.
