A storage apparatus according to an embodiment of the present invention will be described below with reference to fig. 1 to 6.

In the embodiment of the utility model, the storage device can be a refrigerator, a refrigerated cabinet, a retail cabinet, a vending machine or the like.

The relative humidity required for storing different kinds of articles is different, for example, the relative humidity required for storing dry goods, tea leaves and nuts is below 45%, the relative humidity required for storing cosmetics or medicines is between 50% and 60%, and the relative humidity required for storing high-moisture-content food materials such as fruits and vegetables is above 80%.

The embodiment of the utility model provides a storage device, which can carry out accurate humidity control by adding an air duct structure and sending cold air to a chamber of the storage device, and can effectively ensure the storage time of food materials or other articles.

As shown in fig. 1, the cabinet of the storage apparatus defines a refrigerating compartment 100, an evaporator compartment, and a humidity control compartment 200.

The refrigerating chamber 100 is a compartment for storing food materials or other items in the storage apparatus, and the temperature of the refrigerating chamber 100 may be controlled between 1 ℃ and 8 ℃.

The evaporator chamber is a chamber used for preparing circulating cold air in the storage equipment, and when high-temperature air flows through the evaporator arranged in the evaporator chamber, the high-temperature air and the low-temperature air directly exchange heat, so that the temperature of the air is reduced.

The cold air prepared by the evaporator is circularly blown into the storage compartments of the storage equipment, so that the temperature of the storage compartments such as the refrigerating compartment 100 or the humidity control compartment 200 is reduced to reach the temperature for storing articles.

The humidity control chamber 200 belongs to a storage chamber of a storage device, the humidity in the humidity control chamber 200 can be adjusted and controlled, a humidity sensor 210 is arranged in the humidity control chamber 200, and the humidity sensor 210 can acquire humidity data in the humidity control chamber 200.

The humidity control chamber 200 is communicated with the evaporator chamber through a cooling air duct 300, and an air door is arranged in the cooling air duct 300, and the opening and closing state of the air door is controllable.

When the air door in the refrigeration air duct 300 is opened, cold air in the evaporator chamber blows into the humidity control chamber 200, and the humidity in the humidity control chamber 200 is reduced; when the damper in the cooling air duct 300 is closed, the cold air in the evaporator chamber does not blow into the humidity control compartment 200.

The humidity control chamber 200 is communicated with the refrigerating chamber 100 through a humidity control air duct, and a humidity control fan is arranged in the humidity control air duct, and the on-off state of the humidity control fan is controllable.

When the humidity control fan in the humidity control air duct is opened, the air in the refrigerating chamber 100 is blown into the humidity control compartment 200; when the humidity control fan in the humidity control duct is turned off, the air in the refrigerating chamber 100 is not blown into the humidity control compartment 200.

In this embodiment, the user opens the humidity control chamber 200, and closes the humidity control chamber 200 after completing the operation of taking or putting articles, and the humidity or stored articles in the humidity control chamber 200 are changed.

The controller is located the casing of storing equipment, and the controller is connected with air door, wet fan of accuse and humidity transducer 210 electricity, and the controller can be used for acquireing the humidity data that humidity transducer 210 gathered to and control air door and wet fan of accuse and carry out different actions.

Under the condition that the controller is closed after the humidity control chamber 200 is opened, the air door in the refrigeration air duct 300 is controlled to be opened, cold air in the evaporator chamber is blown into the humidity control chamber 200, and the temperature in the humidity control chamber 200 is quickly reduced.

In a practical implementation, the humidity control compartment 200 may be a separate compartment located in the refrigerating compartment 100, and the temperature of the humidity control compartment 200 may be controlled between 1 ℃ and 8 ℃.

The controller controls the opening of the air door in the refrigeration air duct 300 for a first target duration, ensures that the temperature of the humidity control chamber 200 reaches the temperature of the stored articles, and acquires a first humidity value of the humidity control chamber 200 after refrigeration through the humidity sensor 210.

In actual practice, the first target time period may range from 5min to 10min, and the first target time period may be adjusted according to the size of the humidity control chamber 200 or the size of the damper.

It can be understood that the operation of taking or putting articles is not performed every time the humidity control chamber 200 is opened or closed, and whether the air door in the refrigeration air duct 300 needs to be opened or not can be judged by detecting the duration of opening the humidity control chamber 200 and taking the duration of opening the humidity control chamber 200 as a judgment standard, so as to control the humidity control chamber 200 to refrigerate.

For example, when the opening time of the humidity control chamber 200 is detected to be greater than or equal to 3S, the humidity control chamber 200 is closed, which indicates that the humidity or the stored goods in the humidity control chamber 200 may change, the damper in the cooling air duct 300 is controlled to be opened, the humidity control chamber 200 is controlled to be cooled, and the first humidity value is obtained.

In this embodiment, after the damper in the cooling air duct 300 is opened for the first target period of time, the controller controls the damper to be closed, and the cool air prepared in the evaporator chamber is not blown into the humidity control compartment 200 any more.

The humidity control compartment 200 is no longer in gas exchange with the evaporator chamber and the controller obtains a second humidity value for the humidity control compartment 200 after stopping the gas exchange for a second target period of time.

In a practical implementation, the second target time period may be 20min, and the second target time period may be adjusted according to the size of the humidity control chamber 200 or the number of stored items.

In this embodiment, cold air prepared in the evaporator chamber is blown into the humidity control compartment 200 to take away moisture in the humidity control compartment 200, and when the humidity control compartment 200 is brought into a relatively sealed state, moisture in the articles stored in the humidity control compartment 200 is volatilized, so that the humidity of the humidity control compartment 200 is increased.

It will be appreciated that a first humidity value of humidity control compartment 200 after the damper is opened for a first target period of time in refrigerated duct 300 is less than a second humidity value after the damper is closed for a second target period of time.

In this embodiment, the controller may determine the storage humidity required for storing items in the humidity control compartment 200 according to a first humidity value of the humidity control compartment 200 after the damper in the cooling duct 300 is opened for a first target period of time and a second humidity value of the humidity control compartment 200 after the damper is closed for a second target period of time.

The first humidity value of the humidity control chamber 200 is much smaller than the second humidity value, which indicates that the humidity control chamber 200 enters a relatively sealed state, and more moisture of the articles stored in the humidity control chamber 200 volatilizes, so that the articles stored in the humidity control chamber 200 need to be stored in an environment with higher humidity.

For example, when fruits and vegetables are stored in the humidity control compartment 200, the first humidity value obtained through the steps 110 and 120 is much smaller than the second humidity value, and the fruits and vegetables need to be stored in an environment with higher humidity.

The difference between the first humidity value and the second humidity value of the humidity control chamber 200 is not great, which indicates that the humidity control chamber 200 enters a relatively sealed state, and the moisture of the articles stored in the humidity control chamber 200 is less volatilized, so that the articles stored in the humidity control chamber 200 need to be stored in an environment with lower humidity.

For example, when tea leaves or nuts are stored in the humidity control chamber 200, the first humidity value obtained through the steps 110 and 120 is not much different from the second humidity value, and the tea leaves or nuts need to be stored in an environment with higher humidity.

In this embodiment, the controller determines the storage humidity required for the articles stored in the humidity control compartment 200 according to the difference between the first humidity value and the second humidity value of the humidity control compartment 200, and adjusts the air circulation state between the humidity control compartment 200 and the refrigerating compartment 100 by controlling the on-off state of the humidity control fan in the humidity control duct, so that the humidity of the humidity control compartment 200 is within the storage humidity range required for the articles.

It is understood that the items such as fruits and vegetables having a large moisture content are mostly stored in the refrigerating compartment 100, and the air in the refrigerating compartment 100 is air having a high humidity.

When the controller controls the humidity control fan in the humidity control air duct to be opened, the air in the refrigerating chamber 100 is blown into the humidity control chamber 200, the air with higher humidity contacts with the air in the humidity control chamber 200, and the humidity of the humidity control chamber 200 is improved.

When the controller controls the humidity control fan in the humidity control air duct to be closed, the air in the refrigerating chamber 100 is not blown into the humidity control chamber 200 any more, the humidity control chamber 200 is in a relatively sealed state, and the humidity fluctuation degree of the humidity control chamber 200 is not large.

In the related art, some storage devices which realize humidity control by adding a fan appear, the fan is controlled to be turned on or off according to a selection key of a user, and the condition that a wrong key is forgotten or selected easily occurs, so that the articles are deteriorated, excessively air-dried or remoistened.

The controller of the embodiment of the utility model judges the storage humidity required by the articles stored in the humidity control chamber 200 according to the difference degree between the first humidity value and the second humidity value of the humidity control chamber 200, and accurately controls the humidity of the humidity control chamber 200 by controlling the on-off state of the humidity control fan in the humidity control air duct, so that the humidity of the humidity control chamber 200 is in the storage humidity range required by the articles, the phenomenon of deterioration, excessive air drying or moisture regain of the articles is avoided, and the storage time of the articles is prolonged.

According to the storage equipment provided by the embodiment of the utility model, the independent refrigerating air duct 300 and the independent humidity control air duct are added, and the humidity state of the stored articles in the storage equipment is judged according to the humidity data of the humidity control chamber 200, so that the humidity of the humidity control chamber 200 is in the storage humidity range required by the articles, the articles are prevented from being deteriorated, excessively air-dried or remoistened, and the storage time of the articles is prolonged.
