Embodiment Construction
[0025] This embodiment first provides a control method for a refrigerator, which can prevent the dehumidification effect from affecting the dehumidification effect when the dehumidification structure is saturated with water, and ensure the dehumidification capability of the dehumidification structure, thereby ensuring that the humidity in the return air duct is low. figure 1 It is a schematic structural diagram of a return air duct 100 of a refrigerator to which a control method for a refrigerator according to an embodiment of the present invention is applicable.
[0026] like figure 1 As shown, the return air duct 100 may be provided with a front damper 110 and communicate with the storage compartment in a controlled manner through the front damper 110 . The return air duct 100 is used to return the air in the storage compartment to the evaporator room. When the refrigerator is in the normal cooling mode, the front damper 110 is opened and closed according to the actual temp...

The invention provides a refrigerator control method and device. Wherein the control method of the refrigerator includes: detecting the current humidity value at the smell sensor place; obtaining the last humidity value at the smell sensor place, wherein the smell sensor is integrated with a humidity sensor configured to periodically obtain the humidity value at the smell sensor place; calculating the current humidity value at the smell sensor place The difference between the humidity value and the previous humidity value; judging whether the difference is greater than or equal to a preset difference threshold; and if so, determining that the dehumidification structure has reached a saturated state, and controlling the refrigerator to enter a recovery mode. The solution of the present invention can control the refrigerator to enter the restoration mode after determining that the dehumidification structure has reached a saturated state, and restore the dehumidification structure to avoid affecting the dehumidification effect when the dehumidification structure is saturated with water, and ensure the dehumidification capacity of the dehumidification structure. The humidity in the tunnel is low.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a control method and device for a refrigerator. Background technique [0002] With the increasing development of society and the continuous improvement of people's living standards, people's life rhythm is getting faster and faster, so they are more and more willing to buy a lot of food and put them in the refrigerator. The refrigerator has become one of the indispensable household appliances in people's daily life. . [0003] However, when a large amount of food is stored in the refrigerator, the following problems often occur: the user may forget that some food is stored in the refrigerator, causing the food to expire and cause waste; the user cannot determine the freshness of the food, and may accidentally eat stale food Affect physical health. In the current prior art, an odor sensor is provided in the refrigerator, so as to determine the freshness of the food ...
