Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described more fully below by way of examples in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In one embodiment, referring to fig. 1, a humidity control method for a refrigerator is provided, which includes the following steps:
step S200: and selecting a target humidity gear from preset humidity gears.
Specifically, a control device can be used to select a target humidity gear from preset humidity gears, and the control device can be an original main control unit of the refrigerator or can be an independent controller used to control the humidity of the refrigerator. The preset humidity gears refer to humidity gears which are set in a storage or a control device of the refrigerator, the number of the preset humidity gears is not unique, the more the preset humidity gears are, the thinner the humidity difference is, the richer the types of food suitable for storage are, and generally speaking, when the number of the preset humidity gears is three, the preservation requirement of most fruits and vegetables can be met. It can be understood that in other embodiments, the number of the preset humidity gears can be other values, different preset humidity gears meet the storage requirements of different types of food, and the target humidity gear selected from the preset humidity gears can be more specifically adapted to the storage requirements of the food in the refrigerator.
Step S400: and matching the corresponding humidity standard value according to the target humidity gear.
After the target humidity gear is determined, the corresponding humidity standard values can be matched according to the target humidity gear, the humidity standard values corresponding to different target humidity gears are different, the humidity standard values corresponding to the target humidity gears can be correspondingly stored in the memory, and the corresponding humidity standard values can be directly called after the target humidity gear is determined, so that the use is convenient and fast. Further, when most of the food types stored in the refrigerator are vegetables, the humidity standard values corresponding to different target humidity gears meet the high humidity standard, namely, the humidity standard values are greater than or equal to 70% RH, the values are obtained by verifying the vegetable fresh-keeping effect through a large number of experiments, the vegetable fresh-keeping effect, particularly the leaf vegetable food, is good in the high humidity environment, and for example, the melon and fruit food materials are suitable for being stored under the humidity of 80% RH. Taking the number of the preset humidity gears as three as an example, the value range of the humidity standard value a1 corresponding to the first gear H1 can be 85% RH ≤ a1 ≤ 95% RH, the value range of the humidity standard value a2 corresponding to the second gear H2 can be 75% RH ≤ a2 ≤ 85% RH, the value range of the humidity standard value A3 corresponding to the third gear H3 can be 70% RH ≤ A3 ≤ 75% RH, a1 > a2 > A3, and the three ranges are used to distinguish the optimal fresh-keeping humidity capable of encapsulating most of fruit and vegetable food materials, so that the application range is wide. It is understood that in other embodiments, the humidity standard value may be other values as long as one skilled in the art can realize the humidity standard value.
Step S600: and acquiring real-time humidity in the drawer.
Wherein, the drawer is arranged in the refrigerator and used for storing food. The food stored in the drawer and the drawer form an independent space, so that the environmental parameters in the drawer can be conveniently adjusted. The number of the drawers is not unique, when the refrigerator comprises more than two drawers, different kinds of food can be placed in different drawers, or different storage-adjusted food can be placed in different drawers, so that the internal environmental parameters of the drawers can be adjusted according to the food stored in the drawers, and the quality of the stored food can be improved. The device that obtains real-time humidity in the drawer is not exclusive, can adopt humidity transducer to detect the humidity in the drawer for example, and humidity transducer sets up inside the drawer, and the density of the vapor in the drawer air that will sense converts the signal of telecommunication into after sending to controlling means, controlling means through analytic processing alright obtain the real-time humidity in the drawer. The real-time humidity in the drawer is acquired, so that the storage environment of food in the drawer can be monitored in real time, and the food storage condition can be improved.
