Description

Humidity control system and humidity control method for refrigeration equipment

Technical Field

The invention relates to the field of refrigeration equipment, in particular to a humidity control system and a humidity control method for refrigeration equipment.

Background

In order to ensure that the user can obtain the best and most diversified use experience through the simplest operation, the existing refrigeration equipment, such as a refrigerator, a freezer and the like, needs to fully consider the appropriate storage humidity of the stored objects while realizing the refrigeration effect so as to prolong the preservation period of the stored objects.

Taking a refrigerating chamber of a refrigerator as an example, the refrigerating chamber of the existing refrigerator is generally provided with two storage drawers, wherein one storage drawer is a moisturizing drawer and is used for storing fresh vegetables, melons and fruits and other stored objects which are suitable for storing higher humidity; the other storage drawer is a dry object drawer and is used for storing dry goods such as dry fruits, dry vegetables, seasonings, coarse cereals and the like which are suitable for storing the dry goods with lower humidity.

In practical applications, the moisture preservation drawer generally adopts a sealing structure to prevent humidity loss. However, when the moisture preservation drawer is opened, if the moisture preservation drawer is opened by a user to take and place the stored object, the humidity in the moisture preservation drawer may be changed due to the humidity of the external environment and the humidity of the stored object to be newly put in, and even the humidity in the moisture preservation drawer is higher or lower than the default humidity level.

On the other hand, the dry drawer reduces the humidity in the drawer by blowing cold air into the evaporator, thereby creating a low-humidity storage environment. However, after the evaporator stops operating, the humidity in the dry goods drawer will still rise, causing the humidity in the dry goods drawer to be higher than the default humidity level, shortening the storage life of the stored dry goods. In addition, once the dry substance drawer is set, it is no longer able to store fresh vegetables and fruits and other stored substances with high humidity, so that the user may not be able to fully utilize all the space of the refrigerating chamber of the refrigerator.

In addition, the existing refrigerator cannot really automatically control the temperature and the humidity of the refrigerating chamber according to the characteristics of food, for example, the existing refrigerator still needs a user to manually adjust the humidity of the refrigerating chamber. However, a user cannot accurately grasp the preservation requirements of all foods, and the adjustment amount cannot be well controlled during adjustment, so that the existing refrigerator cannot really achieve the effect of prolonging the preservation time.

At present stage, under most of the circumstances, can't provide an effectual scheme for the humidity level in refrigeration plant can be according to the characteristic of the food of depositing in time, nimble regulation storage drawer, more can't maintain the humidity in the storage drawer in the humidity range of relatively stable effectively, thereby influence the fresh-keeping term of the interior storage of storage drawer.

Compared with the prior art, the technical scheme of the invention has the following advantages:

an aspect of an embodiment of the present invention provides a humidity control system for a refrigeration apparatus, the refrigeration apparatus including a first space and a second space, the humidity control system including: a connection passage for communicating the first space and the second space; and the humidity control module responds to a humidity adjusting instruction and controls the connection passage to be conducted so as to control the humidity of the first space and the second space. Compared with the technical scheme that once the dry and wet drawers of the existing refrigeration equipment are set, the dry and wet drawers cannot be mutually converted, so that the existing refrigeration equipment cannot flexibly adjust the humidity in different spaces (such as different drawers), the humidity control system provided by the embodiment of the invention controls the conduction of the connecting passage to control the humidity of the first space and the second space of the refrigeration equipment, so that the humidity in each space of the refrigeration equipment can meet the indication of the humidity adjusting instruction, and intelligent and high-flexibility humidity adjustment is realized among different spaces of the refrigeration equipment.

Further, a humidity difference exists between the first space and the second space, so that during the operation of the refrigeration equipment, after the connection passage is conducted, humidity control can be realized between the first space and the second space.

Further, the humidity control system further comprises: and the connecting air channel is communicated with the first space and the dehumidifying device so as to reduce the humidity in the first space through the dehumidifying device.

Further, the dehumidifying apparatus includes: and the refrigerating unit is used for reducing the humidity of the first space by conveying cold air to the first space according to the principle that the humidity of the gas is correspondingly reduced along with the increase of the temperature of the gas in the closed space.

Further, when the humidity adjusting instruction is received, the humidity control module controls the connection channel to be conducted, and the humidity adjusting instruction is generated in response to that the actual humidity in the first space is lower than a first preset standard humidity or in response to that the actual humidity in the second space is higher than a second preset standard humidity. As understood by those skilled in the art, when the humidity adjustment command is used to instruct to increase the humidity of the space (e.g., the first space) having a lower humidity among the first space and the second space or when the humidity adjustment command is used to instruct to decrease the humidity of the space (e.g., the second space) having a higher humidity among the first space and the second space, due to the humidity difference between the first space and the second space, the humidity control module may control the connection path to be conducted so as to naturally realize the effect instructed by the humidity adjustment command by using the humidity difference between the first space and the second space.

Further, when the humidity adjusting instruction is generated in response to that the actual humidity in the first space is lower than a first preset standard humidity, the humidity control module further controls the humidifier in the second space to be opened and controls the connecting air channel to be closed. It is understood by those skilled in the art that when the humidity adjustment command is used to instruct to increase the humidity of a space (e.g., a first space) having a lower humidity among the first space and the second space, the humidity in the second space is transferred to the first space due to the conduction of the connection path. At this time, in order to prevent the humidity in the second space from being excessively reduced and to increase the humidity rising speed in the first space, the humidity control module may further control the humidifier to be turned on to maintain or raise the humidity in the second space.

Further, when the humidity adjustment instruction is generated in response to that the actual humidity in the second space is higher than a second preset standard humidity, the humidity control module further controls the humidifier arranged in the second space to be turned off and controls the connection air channel to be turned on. It is understood by those skilled in the art that when the humidity adjustment command is used to instruct to decrease the humidity of the space (e.g., the second space) with higher humidity in the first space and the second space, the dry gas in the first space can flow to the second space due to the conduction of the connection path, and at the same time, the moisture in the second space can also flow reversely to the first space. At this time, in order to prevent the humidity in the first space from being excessively increased and to accelerate the humidity reduction speed in the second space, the humidity control module may control the humidifier to be turned off and control the connection duct to be turned on to transmit cool air to the first space, so as to maintain or reduce the humidity in the first space.

Further, a fan is arranged in the connecting passage; when the humidity adjusting instruction is generated in response to the actual humidity in the first space being lower than a first preset standard humidity or in response to the actual humidity in the second space being higher than a second preset standard humidity, the humidity control module further controls the fan to be turned on forward or backward to increase the humidity in the first space or decrease the humidity in the second space. The skilled person is connected to accelerate the humidity control between the first space and the second space by arranging said fan. For example, the fan may be a bi-directional fan, and moisture in the second space may be more rapidly transferred into the first space by a forward operation of the fan; for another example, the dry gas in the first space can be more quickly transferred to the second space by the reverse operation of the fan.

Further, when the humidity of the first space reaches a first preset standard humidity and/or the humidity of the second space reaches a second preset standard humidity, the humidity control module controls the connection passage to be switched off. It will be appreciated by those skilled in the art that when the connection path is closed, the first and second spaces are each returned to a relatively sealed state to prevent loss of internal humidity, and to ensure that the humidity within the first and second spaces can be maintained within the respective desired humidity ranges.

Further, when the humidity adjusting instruction is received, the humidity control module controls the connection channel to be turned off, and the humidity adjusting instruction is generated in response to that the actual humidity in the first space is higher than a first preset standard humidity or in response to that the actual humidity in the second space is lower than a second preset standard humidity. It is understood by those skilled in the art that, when the humidity adjustment command is used to instruct to decrease the humidity of a space (e.g., a first space) having a lower humidity among the first and second spaces or when the humidity adjustment command is used to instruct to increase the humidity of a space (e.g., a second space) having a higher humidity among the first and second spaces, the humidity control module may control the connection path to be turned off so as not to have an opposite effect to the instruction of the humidity adjustment command due to the humidity control between the first and second spaces.

Further, when the humidity adjustment instruction is generated in response to that the actual humidity in the first space is higher than a first preset standard humidity, the humidity control module further controls the connection air duct to be conducted. It is understood by those skilled in the art that when the humidity adjustment instruction is used to instruct to decrease the humidity of the space (e.g., the first space) with lower humidity among the first space and the second space, the cold air may be delivered into the first space by opening the connecting duct to decrease the humidity in the first space.

Further, when the humidity adjustment instruction is generated in response to that the actual humidity in the second space is lower than a second preset standard humidity, the humidity control module further controls a humidifier arranged in the second space to be turned on. It is understood by those skilled in the art that when the humidity adjustment command is used to instruct to increase the humidity of a space (e.g., the second space) having a higher humidity among the first space and the second space, the humidity in the second space may be increased by turning on the humidifier.

Further, the humidity adjusting instruction is generated based on user input, so that the refrigeration equipment can flexibly adjust the humidity in different spaces according to the instruction of a user.

Further, the humidity adjusting instruction is generated according to a comparison result of the actual humidity in the first space and the first preset standard humidity and/or a comparison result of the actual humidity in the second space and the second preset standard humidity, so that when the refrigerating equipment does not receive the instruction of the user, the humidity in different spaces can be intelligently adjusted.

Further, the first preset standard humidity is determined according to the stored materials in the first space; the second preset standard humidity is determined according to the stored objects in the second space, so that the standard humidity in each space is determined more accurately, and the effect of prolonging the fresh-keeping time of the stored objects is achieved. For example, for each space, the standard humidity for the space may be determined based on a respective longest shelf life tradeoff for all storage in the space.

Further, the humidity control system further comprises: shooting equipment which is respectively arranged in the first space and the second space or arranged in a room where the first space and the second space are located; and the image identification module is used for identifying the image acquired by the shooting equipment so as to determine the storage object in the first space or the second space. Those skilled in the art will understand that, through the combination of the photographing apparatus and the image recognition module, the storage objects stored in the first space and the second space can be precisely recognized, so that the humidity control system can accurately determine the standard humidity (i.e., the first preset humidity standard and the second preset humidity standard) in each space.

Further, the humidity control system further comprises: the prompt module first predetermine standard humidity with difference between the actual humidity in the first space exceeds first predetermined threshold value, and/or the second predetermine standard humidity with when difference between the actual humidity in the second space exceeds the second predetermined threshold value, send tip information to when the wrong space of storage thing mistake proofing (if dry object is by wrong wet drawer of placing, perhaps fresh melon and fruit is by wrong dry drawer of placing), can in time send the suggestion to the user, remind this unusual phenomenon of user.

Further, the humidity control system further comprises: and the humidity detection devices are respectively arranged in the first space and the second space so as to collect the humidity in the first space and the second space. As understood by those skilled in the art, the actual humidity in the first space and the actual humidity in the second space are fed back to the outside in real time through the humidity detection device, so that a user can know the actual humidity level in the first space and the actual humidity level in the second space conveniently, and the user can adjust the humidity in the first space and/or the second space timely as required. Or, through humidity detection device real-time to the actual humidity in first space and the second space is fed back to humidity control module, humidity control module also can automatically regulated humidity in first space and/or the second space, in order to ensure actual humidity in the first space can satisfy first predetermined standard humidity, and actual humidity in the second space can satisfy the second predetermined standard humidity.

Further, the first space and the second space are horizontally and/or vertically disposed. Those skilled in the art will understand that the relative placement positions of the first space and the second space can be adaptively adjusted according to the structural design of the refrigeration equipment, so as to save the space occupancy rate.

An embodiment of the present invention further provides a humidity control method for a refrigeration apparatus, where the refrigeration apparatus includes a first space and a second space, and the humidity control method includes: determining a humidity adjustment instruction; and responding to the humidity adjusting instruction, controlling the connection passage between the first space and the second space to be conducted so as to enable the first space and the second space to carry out humidity control. As understood by those skilled in the art, compared with the existing technical solution that the humidity level of a specific space can only be adjusted individually and unidirectionally, the method according to the embodiment of the present invention can adjust the humidity levels in multiple spaces of the refrigeration apparatus simultaneously and bidirectionally through the connection path, so that the refrigeration apparatus can adjust the humidity of each space more flexibly, and meet the diversified needs of users.

Further, the humidity control method further includes: when the actual humidity in the first space reaches a first preset standard humidity, and/or the humidity in the second space reaches a second preset standard humidity, the connection channel is controlled to be cut off to stop the humidity control between the first space and the second space, so that the first space and the second space respectively return to a relatively sealed state, the loss of internal humidity is prevented, and the humidity in the first space and the humidity in the second space can be maintained in respective required humidity ranges.

Detailed Description

As will be understood by those skilled in the art, as mentioned in the background, once the dry and wet drawers of the existing refrigeration equipment are set, they cannot be switched with each other, so that the existing refrigeration equipment cannot flexibly adjust the humidity in different spaces (such as different drawers); moreover, the existing refrigeration equipment can only adjust the humidity level of a specific space independently and unidirectionally.

In order to solve the above technical problem, an embodiment of the present invention provides a humidity control system for a refrigeration apparatus, the refrigeration apparatus including a first space and a second space, the humidity control system including: a connection passage for communicating the first space and the second space; and the humidity control module responds to a humidity adjusting instruction and controls the connection passage to be conducted so as to control the humidity of the first space and the second space.

As will be understood by those skilled in the art, the humidity control system according to the embodiment of the present invention controls the connection of the connection path to perform humidity control on the first space and the second space of the refrigeration device, so that the humidity in each space of the refrigeration device can meet the indication of the humidity adjustment instruction, and intelligent and highly flexible humidity adjustment between different spaces of the refrigeration device is achieved.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 1 is a schematic structural diagram of a humidity control system a1 for a refrigeration device 1 according to an embodiment of the present invention. Wherein, the partial structure of the refrigeration equipment 1 can be referred to fig. 2; in this embodiment, the humidity can be understood as relative humidity, so as to measure and characterize the humidity level in different compartments or storage spaces of the refrigeration apparatus 1 more accurately.

In particular, with reference to fig. 1 and 2, the refrigeration device 1 may comprise a first space 2 and a second space 3.

More specifically, the humidity control system a1 may include: a connection passage 4 for communicating the first space 2 and the second space 3; humidity control module a2, in response to the humidity control instruction, control connecting channel 4 switches on so that first space 2 and second space 3 carry out humidity control, ensure humidity in each space of refrigeration plant 1 can satisfy the instruction of humidity control instruction to realize intelligent, the humidity control of high flexibility between refrigeration plant 1's different spaces.

Further, under normal conditions, the first space 2 and the second space 3 may be in a relatively sealed state, respectively, to keep the humidity inside relatively stable.

As a non-limiting example, a door assembly may be provided on the first space 2 and the second space 3, and a user may open the door assembly to take stored articles from the first space 2 or the second space 3, and may close the door assembly to bring the first space 2 or the second space 3 into a relatively sealed state.

As a variation, referring to fig. 2, a drawer 21 may be provided in each of the first space 2 and the second space 3, and the drawer 21 may be used to store a storage. For example, the drawers 21 in the first space 2 and the second space 3 may be both dry drawers and both wet drawers, or one drawer may be dry and the other drawer may be wet, so as to better meet the diversified needs of users.

Further, the first space 2 and the second space 3 may be in the same compartment (not shown). For example, when the refrigeration apparatus 1 is a refrigerator, the compartment may be a refrigerating compartment of the refrigerator or the like where humidity adjustment may be required.

Further, besides the first space 2 and the second space 3, the compartment may further include other spaces, which may be kept relatively independent from the first space 2 and the second space 3, or the other spaces may also be communicated with the second space 2 and/or the third space 3 through the connecting passage 4, so as to implement the humidity adjustment scheme of the embodiment.

It should be noted that, besides the first space 2 and the second space 3 shown in fig. 2, the refrigeration device 1 may further include a compartment such as a freezing chamber that does not need to be subjected to humidity adjustment frequently, which is not shown in fig. 2 and will not be described herein again because it is not a focus of the embodiment of the present invention.

Further, referring to fig. 2 and 3, a first switch component 41 may be disposed in the connection path 4, and the humidity control module a2 may turn on or off the connection path 4 by controlling the first switch component 41 to act.

Further, during the operation of the refrigeration device 1 (also referred to as the use period, or the power-on period of the refrigeration device 1), there may be a humidity difference between the first space 2 and the second space 3, so that after the connection passage 4 is conducted, humidity exchange can be realized between the first space 2 and the second space 3. During the non-operating state of the refrigeration device 1, for example when it is not powered, there may be no humidity difference between the first and

second housings

2, 3.

Further, the humidity control system a1 may further include: a connecting air duct 5, wherein the connecting air duct 5 can connect the first space 2 with a dehumidifying device (not shown) to reduce the humidity in the first space 2 through the dehumidifying device.

Further, referring to fig. 2 and 4, a second switch component 51 may be disposed in the connecting duct 5, and the humidity control module a2 may control the second switch component 51 to turn on or off the connecting duct 5, so as to reduce or maintain the humidity in the first space 2.

In a preferred embodiment, the dehumidifying apparatus may include: and a refrigerating unit 6 for reducing the humidity of the first space 2 by supplying cold air to the first space 2 according to the principle that the humidity of the gas is reduced in the closed space according to the increase of the temperature of the gas.

Preferably, the refrigeration unit 6 may be an evaporator, and the evaporator may transmit cool air to the first space 2 through the connecting duct 5 to reduce the humidity of the first space 2.

Further, the refrigeration apparatus 1 may further include: a humidifier 7 to humidify the inside of the second space 3.

In a preferred example, referring to fig. 2, the humidifier 7 may be disposed in the second space 3 to rapidly raise the humidity in the second space 3.

Alternatively, the humidifier 7 may be disposed in a compartment where the first space 2 and the second space 3 are located, and is communicated with the second space 3, so as to reserve more storage space for the second space 3 and increase the humidity of the second space 3.

Further, when receiving the humidity adjustment instruction, the humidity control module a2 controls the connection path 4 to be conducted, and the humidity adjustment instruction is generated in response to that the actual humidity in the first space 2 is lower than a first preset standard humidity, or is generated in response to that the actual humidity in the second space 3 is higher than a second preset standard humidity. It is understood by those skilled in the art that, when the humidity adjustment command is used to instruct to increase the humidity of the space (e.g., the first space 2) having the lower humidity among the first space 2 and the second space 3 or when the humidity adjustment command is used to instruct to decrease the humidity of the space (e.g., the second space 3) having the higher humidity among the first space 2 and the second space 3, due to the humidity difference between the first space 2 and the second space 3, the humidity control module a2 may control the connection path 4 to be conducted so as to naturally realize the effect instructed by the humidity adjustment command using the humidity difference between the first space 3 and the second space 3.

Further, a fan 42 may be provided in the connection passage 4; when the humidity adjustment command is generated in response to the actual humidity in the first space 2 being lower than the first predetermined standard humidity, or in response to the actual humidity in the second space 3 being higher than the second predetermined standard humidity, the humidity control module a2 may further control the fan 42 to be turned on in a forward or reverse direction, so as to increase the humidity in the first space 2 or decrease the humidity in the second space 3. The skilled person will be connected to accelerate the humidity control between the first space 2 and the second space 3 by arranging said fan 42. For example, the fan 42 may be a bidirectional fan, and moisture in the second space 3 may be more rapidly transferred into the first space 2 by the forward operation of the fan 42; for another example, the drying gas in the first space 2 may be more quickly transferred to the second space 3 by the reverse operation of the fan 42.

In a typical application scenario, the drawer 21 in the first space 2 may be set as a dry drawer by default to store dry materials, and the drawer 21 in the second space 3 may be set as a wet drawer by default to store fresh food, and accordingly, the humidity inside the first space 2 is lower than that inside the second space 3.

Further, the first space 2 and the second space 3 may be two relatively sealed spaces, respectively, in a normal condition, so as to maintain the internal humidity stable within a desired humidity range.

Further, when the humidity adjustment command is generated in response to the actual humidity in the first space 2 being lower than the first predetermined standard humidity, that is, the humidity inside the first space 2 needs to be increased, the humidity control module a2 may control the first switch component 41 to operate to conduct the connection path 4, so that the moisture in the second space 3 can flow into the first space 2 through the connection path 4, thereby increasing the humidity inside the first space 2.

For example, when the actual humidity inside said first space 2 is lower than said first preset standard humidity; for another example, the application scenario may be applicable when the drawer 21 in the first space 2 needs to be changed from a dry drawer to a wet drawer.

In this application scenario, when the actual humidity inside the first space 2 is lower than the minimum value of the numerical range, the humidity adjustment instruction may be triggered.

Further, when the humidity in the first space 2 reaches the first preset standard humidity, the humidity control module a2 may control the first switch component 41 to act to close the connection path 4. At this time, the first space 2 and the second space 3 are respectively restored to a relatively sealed state to prevent the internal humidity from being lost, and the humidity inside the first space 2 and the second space 3 can be maintained within the respective required humidity ranges.

Further, when the humidity adjustment command is generated in response to the actual humidity in the first space 2 being lower than a first predetermined standard humidity, that is, the humidity in the first space 2 needs to be increased, the humidity control module a2 may further control the humidifier 7 in the second space 3 to be turned on and control the connecting air duct 5 to be turned off. It is understood by those skilled in the art that when the humidity adjustment command is used to instruct to increase the humidity of the space (e.g., the first space 2) having the lower humidity among the first space 2 and the second space 3, the moisture in the second space 3 is transferred to the first space 2 due to the conduction of the connection path 4. At this time, in order to prevent the humidity in the second space 3 from being excessively decreased and to increase the humidity rising speed in the first space 2, the humidity control module a2 may control the humidifier 7 to be turned on to maintain or raise the humidity in the second space 3. Wherein, the humidifier 7 can be intermittently opened to save the electricity consumption.

Further, while the connection path 4 is conducted to transmit the moisture to the first space 2, the fan 42 may be turned on to operate in a forward direction to transfer the moisture in the second space 3 to the first space 2.

In another exemplary application scenario, when the humidity adjustment command is generated in response to the actual humidity in the second space 3 being higher than a second predetermined standard humidity, that is, the humidity inside the second space 3 needs to be reduced, the humidity control module a2 may also control the first switch component 41 to act to conduct the connection path 4, so that the dry gas in the first space 2 can naturally sink into the second space 3 through the connection path 4, thereby reducing the humidity inside the second space 3. Furthermore, in order to accelerate the circulation speed of the dry gas from the first space 2 to the second space 3, the connecting air duct 5 may be conducted at the same time to increase the pressure in the first space 2, so as to promote the dry gas in the first space 2 to flow to the second space 3 more quickly.

For example, when the actual humidity inside the second space 3 exceeds the second preset standard humidity; for another example, the application scenario may be applicable when the drawer 21 in the second space 3 needs to be changed from a wet drawer to a dry drawer.

In this application scenario, when the actual humidity inside the second space 3 is higher than the maximum value of the numerical range, the humidity adjustment instruction may be triggered.

Further, when the humidity in the second space 3 reaches the second preset standard humidity, the humidity control module a2 may control the first switch component 41 to act to close the connection path 4. At this time, the first space 2 and the second space 3 are respectively restored to a relatively sealed state to prevent the internal humidity from being lost, and the humidity inside the first space 2 and the second space 3 can be maintained within the respective required humidity ranges.

Further, in this application scenario, while the connection passage 4 is turned on to transmit the dry gas to the second space 3, the humidity control module a2 may also control the humidifier disposed in the second space 3 to be turned off and control the connection duct 5 to be turned on. It is understood by those skilled in the art that when the humidity adjustment command is used to instruct to decrease the humidity of the space (e.g. the second space 3) with higher humidity in the first space 2 and the second space 3, the dry gas in the first space 2 can flow to the second space 3 due to the conduction of the connection path 4, and at the same time, the moisture in the second space 3 can also flow to the first space 2 reversely. At this time, in order to prevent the humidity in the first space 2 from being excessively increased and to increase the humidity decreasing speed in the second space 3, the humidity control module a2 may control the humidifier 7 to be turned off and control the connection duct 5 to be turned on to transmit the cold air to the first space 2, so as to maintain or decrease the humidity in the first space 2, and ensure that the humidity in the first space 2 is not affected by the moisture in the second space 3 while the dry air is transmitted to the second space 3.

Further, while the connecting passage 4 is conducted to transmit the dry gas to the second space 3, the fan 42 may be turned on to operate in a reverse direction to accelerate the air circulation from the first space 2 to the second space 3.

In another typical application scenario, when the humidity adjustment command is generated in response to the actual humidity in the first space 2 being higher than a first predetermined standard humidity, that is, the humidity inside the first space 2 needs to be reduced, the humidity control module a2 may control the first switch component 41 to act to close the connection path 4. Meanwhile, the humidity control module a2 may also control the second switch component 51 to operate to conduct the connecting duct 5, so that the cold air of the refrigeration unit 6 can enter the first space 2, thereby reducing the humidity inside the first space 2. It is understood by those skilled in the art that when the humidity adjustment instruction is used to instruct to decrease the humidity of the lower-humidity space (e.g. the first space 2 in the present application scenario) of the first space 2 and the second space 3, the cold air can be delivered into the first space 2 by turning on the connecting duct 5 to decrease the humidity in the first space 2.

This application scenario may apply, for example, when the actual humidity inside the first space 2 is higher than the first preset standard humidity.

Further, when the humidity in the first space 2 is reduced to the first preset standard humidity, the humidity control module a2 may control the second switch component 51 to act to turn off the connecting air duct 5. At this time, the first space 2 is restored to a relatively sealed state to prevent the internal humidity from being lost, and to ensure that the humidity inside the first space 2 can be maintained stable.

In another exemplary application scenario, when the humidity adjustment command is generated in response to the actual humidity in the second space being lower than a second predetermined standard humidity, that is, the humidity inside the second space 3 needs to be increased, the humidity control module a2 may control the first switch component 41 to act to close the connection path 4. Meanwhile, the humidity control module a2 may also control the humidifier 7 disposed in the second space 3 to be turned on, so as to raise the humidity inside the second space 3. It is understood by those skilled in the art that when the humidity adjustment instruction is used to instruct to increase the humidity of the space with higher humidity (such as the second space 3 in the present application scenario) of the first space 2 and the second space 3, the humidity in the second space 3 can be increased by turning on the humidifier 7.

For example, the present application scenario may be applied when the actual humidity inside the second space 3 is lower than the second preset standard humidity. Wherein, the humidifier 7 can be intermittently opened to save electricity.

It is understood by those skilled in the art that, when the humidity adjustment instruction is used to instruct to decrease the humidity of the space (e.g., the first space 2) having the lower humidity among the first and

second spaces

2 and 3, or when the humidity adjustment instruction is used to instruct to increase the humidity of the space (e.g., the second space 3) having the higher humidity among the first and

second spaces

2 and 3, the humidity control module a2 may control the connection path 4 to be turned off so as not to have an opposite effect to the instruction of the humidity adjustment instruction due to the humidity control between the first and

second spaces

2 and 3.

It should be noted that, in practical applications, a person skilled in the art may change the default humidity of the drawer 21 in the first space 2 and the default humidity of the drawer 21 in the second space 3 according to requirements. For example, the drawer 21 in the first space 2 may default to a wet drawer, and the drawer 21 in the second space 3 may default to a dry drawer; for another example, the drawer 21 in the first space 2 and the drawer 21 in the second space 3 may be both set as a wet drawer by default, or both set as a dry drawer by default. The skilled person understands that no matter how the default humidity of the two drawers is set, the on/off of the connection path 4 can be controlled by the humidity control module a2 according to the example in the above application scenario to realize the adjustment of the humidity in the two drawers, and stabilize the respective humidity of the two drawers when the humidity adjustment is not needed.

As a non-limiting example, the humidity adjustment command may be generated based on user input, so that the refrigeration apparatus 1 can flexibly adjust the humidity in different spaces according to the user's instruction. For example, the humidity control module a2 may show the humidity in the first space 2 and the second space 3 to a user in real time and adjust the humidity inside the first space 2 and/or the second space 3 in response to an instruction input by the user.

As a variation, the humidity adjustment instruction may also be generated according to a comparison result between the actual humidity in the first space 2 and a first preset standard humidity, and/or a comparison result between the actual humidity in the second space 3 and a second preset standard humidity, so that the refrigeration apparatus 1 can still intelligently adjust the humidity in different spaces without receiving a user instruction.

Wherein the first and second preset standard humidities may be determined according to storage characteristics of the first and

second spaces

2 and 3, respectively. For example, when the first space 2 is used for storing dry materials, the first preset standard humidity may be set to be low; when the second space 3 is used for storing fresh vegetables and fruits, the second predetermined standard humidity can be set higher.

In a preferred embodiment, the first preset standard humidity may be determined according to the stored contents in the first space 2; the second preset standard humidity can be determined according to the stored objects in the second space 3, so that the standard humidity in each space can be determined more accurately, and the effect of prolonging the fresh-keeping time of the stored objects is achieved. For example, for each space, the standard humidity for the space may be determined based on a respective longest shelf life compromise for all stored items in the space.

Further, the humidity control system a1 may further include: a photographing apparatus 15 respectively provided in the first space 2 and the second space 3, or provided in a room where the first space 2 and the second space 3 are located; and the image recognition module a3 is used for recognizing the image acquired by the shooting device 15 so as to determine the stored objects in the first space 2 or the second space 3. Those skilled in the art will understand that, through the combination of the photographing device 15 and the image recognition module a3, the storage objects stored in the first space 2 and the second space 3 can be precisely recognized, so that the humidity control system a1 can accurately determine the standard humidity (i.e. the first preset humidity standard and the second preset humidity standard) in each space.

For example, referring to fig. 2, the photographing apparatus 15 may be respectively disposed at upper surfaces inside the first and

second spaces

2 and 3, such as positions near the humidity sensor 8, to precisely photograph all corners inside the first and

second spaces

2 and 3.

For another example, the photographing device 15 may be installed at the top of a compartment where the first space 2 and the second space 3 are located, so that when the first space 2 or the second space 3 is opened, the stored objects in the first space 2 and the second space 3 can be photographed by the same photographing device 15. Alternatively, a plurality of shooting devices 15 may be provided in the room, so as to shoot the stored objects in the first space 2 and the second space 3 from different angles, thereby improving the image recognition accuracy of the image recognition module a 3.

As a non-limiting example, the image recognition module a3 may be independent of the refrigeration device 1 and communicate with the humidity control module a2 and the camera device 15 to transmit the recognition result of the image captured by the camera device 15 to the humidity control module a 2.

For example, the image recognition module a3 may compare the image of the first space 2 or the second space 3 collected by the photographing apparatus 15 with a preset database, in which the image and the suitable storage humidity of at least one food are stored, to determine the suitable storage humidity of each storage object stored in the first space 2 or the second space 3.

As a variant, the image recognition module a3 can also be integrated in the refrigeration device 1 together with the humidity control module a 1.

Further, taking the determination of the first preset standard humidity of the first space 2 as an example, after the recognition result of all the stored objects stored in the first space 2 by the image recognition module a3 is obtained, the humidity control module a2 may perform fitting calculation on the suitable stored humidity of each of the stored objects to determine a compromise humidity value as the first preset standard humidity, so as to enable the preservation time of all the stored objects in the first space 2 under the first preset standard humidity to be prolonged as much as possible.

Wherein the photographing device 15 and the image recognition module a3 may be operated periodically. Alternatively, in a normal state, the photographing device 15 and the image recognition module a3 may be in a sleep state, and each time the first space 2 or the second space 3 is opened (i.e., changed from the relatively sealed state to the open state), the photographing device 15 and the image recognition module a3 are woken up to perform the image capturing and recognition operation in the present embodiment.

Further, the humidity control system a1 may further include: prompt module a4 first preset standard humidity with difference between the actual humidity in the first space 2 exceeds first preset threshold value, and/or the second preset standard humidity with when difference between the actual humidity in the second space 3 exceeds the second preset threshold value, send tip information to in the wrong space of storage thing mistake proofing (if dry object is placed wet drawer by the mistake, perhaps fresh melon and fruit is placed by the mistake and is taken out the dry drawer) the time, can in time send the suggestion to the user, remind this unusual phenomenon of user.

Preferably, the first preset threshold and the second preset threshold may be preset by a user, or may also be set by the humidity control module a3 by default.

Those skilled in the art understand that, the actual humidity in the first space 2 and the second space 3 is fed back to the outside in real time through the humidity detection device 8, which is beneficial for the user to know the actual humidity level in the first space 2 and the second space 3, so that the user can adjust the humidity in the first space 2 and/or the second space 3 as required in time. Or, through humidity detection device 8 real-time to the actual humidity in first space 2 and the second space 3 is fed back to humidity control module a2, humidity control module a2 also can automatically regulated humidity in first space 2 and/or the second space 3, in order to ensure actual humidity in first space 2 can satisfy first preset standard humidity, and actual humidity in the second space 3 can satisfy the second preset standard humidity.

As a non-limiting example, referring to fig. 2, the humidity detection device 8 may be disposed on the upper surfaces (which may be around the photographing apparatus 15) inside the first space 2 and the second space 3, respectively, so as to detect the humidity change inside the first space 2 and the second space 3 more conveniently and quickly. In practical applications, the humidity detection device 8 may be disposed at any position in the first space 2 and the second space 3, as long as it can quickly and accurately detect the humidity change in the drawer, which is not limited in this embodiment.

Preferably, the humidity detection device 8 may be a humidity sensor.

Further, the refrigeration apparatus 1 may further include: a temperature detection device 9, said temperature detection device 9 being arrangeable in a compartment in which said first space 2 and second space 3 are located, to detect a temperature in said compartment. Those skilled in the art understand that the actual temperatures of the compartments where the first space 2 and the second space 3 are located are fed back outwards in real time through the temperature monitoring device 9, which is beneficial for a user or the humidity control module a2 to adjust the temperature of the compartments timely as required, and ensures that the compartments obtain a good refrigeration effect. Further, the temperature of the compartment may be regulated by the refrigeration unit.
