As shown in fig. 4 and 5, the humidifying device 600 includes a first container 610, a water absorbing member 620 and a driving assembly 630; first container 610 includes a reservoir 611 and an access port 612 in communication with reservoir 611; the absorbent member 620 can enter and exit the reservoir 611 through the access hole 612 such that the absorbent member 620 has a first state 621 at least partially protruding outside the first container 610 and a second state 622 at least partially protruding into the reservoir 611; the driving assembly 630 is in transmission connection with the water absorbing member 620 to drive the water absorbing member 620 to switch between a first state 621 and a second state 622; when the water absorbing member 620 is in the first state 621, at least a portion of the water absorbing member 620 can extend into the air duct 130 of the refrigeration unit 10.

In this way, when the humidifying device 600 is applied to the refrigeration equipment 10, a suitable liquid is injected into the liquid storage cavity 611, the water absorbing member 620 can extend into the liquid storage cavity 611 to absorb the liquid, and the water absorbing member 620 is in the second state 622; then, the driving assembly 630 acts to drive the water absorbing member 620 to move from the second state 622 to the first state 621, so that at least a portion of the water absorbing member 620 can extend into the air duct 130 of the refrigeration device 10, the liquid on the water absorbing member 620 can be evaporated in the air duct 130, the humidity of the air flow in the air duct 130 is increased, the humidity of the air flow entering the refrigerating chamber 110 can be increased, the water lost from the refrigerating chamber 110 can be supplemented, the humidity environment of the refrigerating chamber 110 can be maintained, and the food preservation effect can be improved.

Specifically, when the refrigeration device 10 is used, the compressor 200 operates to deliver the refrigerant to the inside of the evaporator 300, and the airflow generating assembly 400 generates airflow blowing toward the refrigerating chamber 110, so that the heat exchange chamber 120 forms negative pressure to suck external air into the evaporator 300 for exchange, and the temperature of the airflow blowing toward the refrigerating chamber 110 is low, thereby having the effects of refrigeration and freshness preservation. Meanwhile, the control device 500 can be used for controlling the driving assembly 630 to move, so that the water absorbing member 620 moves to the first state 621, at least part of the water absorbing member 620 can extend into the air duct 130, the liquid on the water absorbing member 620 can be evaporated in the air duct 130, the humidity of the air flow in the air duct 130 is improved, the humidity of the air flow entering the refrigerating chamber 110 can be further improved, the water lost from the refrigerating chamber 110 can be supplemented, the humidity environment of the refrigerating chamber 110 can be maintained, and the food fresh-keeping effect can be improved.

In addition, it can be understood that the humidification device 600 humidifies the air in the air duct 130, so that the condensation of water vapor into water drops in the refrigerating chamber 110, which are in contact with food, can be reduced, and the food decay is easily accelerated, which is not beneficial to improving the fresh-keeping effect.

As shown in fig. 3, in some embodiments, the refrigeration device 10 further includes a humidity detection device 700 for detecting the humidity level of the refrigerating compartment 110, the humidity detection device 700 is disposed on the housing assembly 100; the control device 500 can calculate the humidity value of the refrigerating chamber 110 according to the humidity information detected by the humidity detection device 700; when the humidity value of the refrigerating compartment 110 is less than or equal to the set value, the control device 500 can control the driving assembly 630 to operate so as to move the water absorbing member 620 to the first state 621, and can control the air flow generating assembly 400 to operate so as to generate the air flow blowing toward the refrigerating compartment 110. Thus, the humidity condition of the refrigerating chamber 110 can be known in time through the humidity detection device 700, so that the control device 500 can calculate the humidity value of the refrigerating chamber 110 according to the humidity information detected by the humidity detection device 700; when the humidity value of the refrigerating chamber 110 is less than or equal to the set value, the control device 500 can control the driving assembly 630 to move so as to move the water absorbing member 620 to the first state 621, and can control the airflow generating assembly 400 to move so as to generate the humidified airflow blown to the refrigerating chamber 110, thereby improving the humidity value of the refrigerating chamber 110 and ensuring the fresh-keeping effect of the refrigerating chamber 110.

It should be noted that the specific implementation manner of the "humidity detection device 700" may be various, including but not limited to a wet bulb hygrometer, an electronic humidity sensor, a moisture meter, and the like.

Optionally, in some embodiments, the humidity detecting device 700 includes a temperature and humidity detector, so that the temperature and the humidity of the refrigerating compartment 110 can be synchronously detected, so as to maintain the humidity and the temperature of the refrigerating compartment 110, and improve the preservation effect.

On the basis of any of the humidity detecting devices 700, in some embodiments, the control device 500 can control the compressor 200 to be in the non-activated state when the humidity value of the refrigerating compartment 110 is less than or equal to the set value. That is, when the humidifying function of the refrigerating apparatus 10 is turned on, the compressor 200 is in a stopped state, and the airflow generating assembly 400 is operated to generate a humidifying airflow blown toward the refrigerating compartment 110, so as to enhance the humidifying effect.

In some embodiments, the compressor 200 is also in the inactive state when the temperature of the refrigerating compartment 110 is less than or equal to the preset temperature value, so as to save energy. When the temperature of the refrigerating chamber 110 is higher than the preset temperature value and the humidifying function is not started, the compressor 200 is started, the non-evaporator 300 provides a refrigerant medium to cool the gas in the heat exchange chamber 120, and the airflow generating assembly 400 sends the cooling airflow into the refrigerating chamber 110 to reduce the ambient temperature of the refrigerating chamber 110.

Thus, when humidification is not required, the control device 500 can control the driving assembly 630 to move to drive the water absorbing member 620 to move from the first state 621 to the second state 622, so that the water absorbing member 620 is located in the liquid storage cavity 611 to absorb the liquid in the liquid storage cavity 611, and prepare for humidification again.

Specific examples of the "water absorbing member 620" include, but are not limited to, water absorbing fibers, water absorbing sponges, and other members capable of absorbing water.

It should be noted that the controller generally controls the overall operation of the refrigeration apparatus 10, such as temperature adjustment, humidification, shutdown, startup, and the like. The controller can be a programmable controller, a motion control card, a microcomputer and other control devices.

In some embodiments, the controller may include one or more processors to execute instructions to perform all or a portion of the steps of the methods described above.

In addition, the communication control means between the controller and each of the actuators (such as the driving assembly 630, the compressor 200, the airflow generating assembly 400) and the feedback element humidity detecting device 700 or the temperature detecting device) belongs to the conventional technology, and is not described herein again.

The "communication connection" may be implemented by using a wired communication technology or a wireless communication technology, and is not described herein in detail as belonging to the conventional technology. Further, the communication connection between the above-mentioned devices may be a direct communication connection. Or may be an indirect communication connection.

When the water absorbing member 620 is in the first state 621, the cover plate 640 is disposed against the side wall of the air duct 130; when the absorbent member 620 is in the second state 622, the cover 640 shields the access opening 612. Therefore, the driving assembly 630 is utilized to drive the water absorbing member 620 and the cover plate 640 to rotate synchronously, when the water absorbing member 620 is in the first state 621, the cover plate 640 is arranged by being attached to the side wall of the air duct 130, the gas fluid in the air duct 130 is not affected, and the air in the air duct 130 is conveniently humidified by the water absorbing member 620.

In addition to any of the embodiments described above, as shown in fig. 4 and 5 or fig. 6 and 7, in some embodiments, the driving assembly 630 is disposed on the first container 610 and is disposed adjacent to the access hole 612.
