[0039] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0040] A refrigerator is a refrigeration device that maintains a constant low temperature. It is mainly used to refrigerate and freeze food and other items. Due to the limitation of the refrigeration effect of direct cooling refrigerators, air-cooled refrigerators have gradually replaced direct cooling refrigerators and become the mainstream. However, the long-term contact of the ingredients in the air-cooled refrigerators with circulating air accelerates the loss of moisture on the surface of the ingredients. The greater the wind speed, the more serious the surface water loss. Therefore, the relative humidity of air-cooled refrigerators is low, which can easily cause the stored ingredients to dry out, affecting the taste and nutritional value, which is a major pain point for consumers.

[0041] In addition, existing refrigerator cabinets mainly focus on the humidity control of the refrigerator compartment, providing different storage humidity environments for different foods, while the moisture retention scheme of the freezer area is less studied. Different types of food have different optimal storage humidity. In addition to the refrigerator compartment, the high humidity demand of the freezer compartment must also be considered to prevent frozen meat from shrinking and becoming woody, and frozen pasta from cracking on the surface. Therefore, how to adjust the relative humidity of the internal space of the refrigerator refrigerator compartment, ice room and freezer compartment is an urgent problem to be solved.

[0042] The moisturizing refrigerator provided in the present application adopts two methods, namely drawer sealing and fan adjustment, to control the relative humidity of the drawer, which helps to maintain humidity stability and reduce relative humidity fluctuations. It can meet the appropriate storage humidity requirements of different foods, effectively adjust the relative humidity of the internal space of the refrigerator's refrigerator compartment, ice room and freezer compartment, further enhance the preservation effect, and realize dry and wet graded storage.

[0043] The specific structure of the moisturizing refrigerator and refrigerator control method provided by the present application is described in detail below in conjunction with the accompanying drawings.

[0044] Reference Figure 1-Figure 2 As shown, the embodiment of the present application provides a moisturizing refrigerator, comprising a box body 100, a moisturizing drawer assembly 200 disposed in the compartment, and a fan 300 disposed in the compartment, the fan 300 cooperates with the moisturizing drawer assembly 200;

[0045] The box body 100 may be a conventional refrigerator, and a plurality of compartments are arranged inside the box body 100. The box body 100 is provided with a control system, and the control system may be a conventional electric control system;

[0046] The moisturizing drawer assembly 200 may be a sealed drawer, and a through hole 211 and a damper 221 are respectively provided on both sides of the moisturizing drawer assembly 200. The through hole 211 is a conventional through hole, and a plurality of through holes 211 are provided;

[0047] The damper 221 is a conventional electric damper, and the control system controls the opening and closing of the damper 221;

[0048] The fan 300 corresponds to the damper 221, and the fan 300 is a conventional micro fan. When the control system controls the damper 221 and the damper 300 to open, the fan 300 draws out the relatively humid air in the moisturizing drawer assembly 200 through the damper 221, so that the relatively drier air in the cabin enters the moisturizing drawer assembly 200 through the through hole 211, and the air humidity in the moisturizing drawer assembly 200 is reduced, thereby adjusting the humidity of the food storage environment.

[0049] In one embodiment, the control system is electrically connected to the monitoring system and the memory. The monitoring system is arranged in the moisturizing drawer assembly 200. The monitoring system is used to photograph the food in the moisturizing drawer assembly 200, generate image information, and transmit it to the control system; the memory stores a variety of food picture information and the corresponding optimal storage humidity; the control system determines the food information in the moisturizing drawer assembly 200 based on the image information and the food picture information stored in the memory; determines the optimal air humidity in the moisturizing drawer assembly 200 based on the food information in the moisturizing drawer assembly 200 and the optimal storage humidity information of the food stored in the memory; and controls the switch of the fan 300 and the damper 221 according to the optimal air humidity.

[0050] Among them, determining the type of food by picture information and then determining the optimal storage humidity for each food is a conventional identification technology and will not be elaborated here; after determining the optimal storage humidity for each food, the control system can determine the optimal storage humidity with the highest humidity as the optimal air humidity in the moisturizing drawer assembly 200, and the control system can also determine the average optimal storage humidity of multiple foods as the optimal air humidity in the moisturizing drawer assembly 200 according to the type of food.

[0052] Furthermore, the user may also directly input the optimal air humidity in the moisturizing drawer assembly 200 to the control system through the input module, and the control system controls the switch of the fan 300 and the damper 221 according to the optimal air humidity in the moisturizing drawer assembly 200.

[0053] When the optimal air humidity in the moisturizing drawer assembly 200 is greater than or equal to the first threshold humidity, it is judged that the suitable humidity environment of the moisturizing drawer assembly 200 is a high humidity environment. At this time, the control system controls the damper 221 to be closed, and only the through hole 221 is opened, and the moisturizing drawer assembly 200 is in a relatively sealed state, thereby ensuring the humidity in the moisturizing drawer assembly 200; conversely, when the optimal air humidity in the moisturizing drawer assembly 200 is less than the first threshold humidity, it is judged that the suitable humidity environment of the moisturizing drawer assembly 200 is a low humidity environment. At this time, the control system controls the damper 221 and the fan 300 to be opened, and the fan 300 draws out the relatively humid air in the moisturizing drawer assembly 200 through the damper 221, so that the drier air in the cabin enters the moisturizing drawer assembly 200 through the through hole 211, thereby reducing the air humidity in the moisturizing drawer assembly 200.
