Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

An embodiment of the present application discloses a refrigerator 100, as shown in fig. 1, including a compartment 110, an end plate 120, and an air pump 130. The compartment 110 has a chamber 1101 for placing articles therein, and a storage opening 111, an air inlet 112, and a drain opening 113 communicating with the chamber 1101. The end plate 120 is movably arranged relative to the compartment 110 and can open or seal the storage opening 111, when the end plate 120 is sealed and arranged at the storage opening 111, the cavity 1101 of the compartment 110 is sealed, and when the end plate 120 is removed from the storage opening 111, the storage opening 111 communicates the cavity 1101 with the outside for articles to be put in or taken out. The air pump 130 is communicated with the chamber 1101 through the air inlet 112 and the water outlet 113, the air pump 130 can inflate and pressurize the chamber 1101 through the air inlet 112, and the water outlet 113 can discharge water condensed in the chamber 1101 to reduce the humidity of the chamber 1101.

Since the chamber 1101 cannot be constantly sealed, when it is necessary to take out or put in an article through the storage port 111, the relative humidity inside the chamber 1101 may increase due to the intrusion of air outside the chamber 1101; alternatively, the moisture content of the chamber 1101 is increased by transpiration of the high moisture food such as fruit and vegetable stored in the chamber 1101. In the refrigerator 100 of the present application, when the end plate 120 is sealed and disposed at the sealed storage opening 111, the volume of the chamber 1101 is fixed, the relative air volume in the chamber 1101 and the moisture content in the air are determined, when other conditions are not changed, the air pump 130 inflates the chamber 1101 through the air inlet 112, the pressure in the chamber 1101 increases, so that excessive moisture on the articles and condensation on the surfaces of the articles are emitted into the air, the relative humidity of the air increases, when the pressure increases to a certain degree, the relative humidity reaches 100%, the moisture is precipitated and condensed from the air in the chamber 1101, and the water outlet 113 of the air pump 130 can pump out the condensed water, so as to reduce the humidity in the chamber 1101, and prevent the food in the chamber 1101 from being wetted or rotten due to the condensation.

Because the air pressure in the chamber 1101 is also reduced in the process of draining the chamber 1101 through the drainage port 113, the condensed water is easy to be diffused into the air again, and the condensed water can be rapidly pumped out by the air pump 130, so that the moisture in the air is reduced again, and the humidity of the chamber 1101 is reduced to the maximum extent. After the air pump 130 pumps out the condensed water, the air can be continuously pumped out through the water outlet 113 to reduce the pressure, so that the pressure in the chamber 1101 is restored to the normal pressure value, and the user can open the drawer 140 conveniently.

As shown in fig. 1, the compartment 110 may be disposed in a refrigerating chamber of the refrigerator 100, and when the refrigerator 100 is normally cooled, the compartment 110 is sealed, and air in the refrigerating chamber circulates outside the compartment 110 to cool the compartment 110, thereby maintaining a certain temperature in the compartment 110. When compartment 110 is open to place or take items, the air from the fresh food compartment enters chamber 1101, which is typically relatively humid, so that air intruding into chamber 1101 increases the relative humidity within chamber 1101. In addition, the chamber 1101 is a relatively sealed space, and the placed object may continuously emit water vapor under the transpiration to increase the relative humidity in the chamber 1101, and if the placed object is fruit or vegetable, the relative humidity may reach 100% under the transpiration, and at this time, the air pump 130 is required to adjust the humidity.

Alternatively, compartment 110 may be a separate refrigerator compartment. Both the ingress of air outside the chamber 1101 and the transpiration of the items stored within the chamber 1101 result in an increase in the moisture content within the chamber 1101.

In one embodiment, as shown in fig. 2 and 3, the refrigerator 100 further includes a drawer 140 movably disposed in the compartment 110 for placing articles, the end plate 120 is disposed on the drawer 140, the end plate 120 seals the storage opening 111 when the drawer 140 extends into the compartment 110 from the storage opening 111, and the end plate 120 opens the storage opening 111 when the drawer 140 is drawn out of the compartment 110 from the storage opening 111. Through the movable arrangement of drawer 140 in compartment 110, when needing to place articles in compartment 110 or take out articles, drawer 140 can be taken out from compartment 110, be convenient for put in order and put in articles, also be convenient for look over and take out articles. Meanwhile, the drawer 140 can separate the articles from the inner wall of the compartment 110, which is beneficial to keeping the inner wall of the compartment 110 relatively clean and convenient for the user to manage. In addition, the air pump 130 pressurizes the chamber 1101, so that after water in the air is analyzed and condensed, the condensed water flows to the bottom of the compartment 110 under the action of gravity, the drawer 140 separates the articles from the compartment 110, the articles are protected, contact between the articles and the condensed water is reduced as much as possible before the condensed water is discharged, and the articles are prevented from being affected with damp or deteriorated.

In order to enhance the sealing between endplate 120 and compartment 110, as shown in fig. 2-4, a first sealing ring 121 is disposed between endplate 120 and compartment 110, and first sealing ring 121 forms a seal between endplate 120 and top, side, and

bottom walls

117, 116 of compartment 110, thereby maintaining the sealing of chamber 1101 and reducing the ingress of external moisture. Specifically, first seal ring 121 may be disposed on a side of end plate 120 facing compartment 110, or on a side of compartment 110 facing end plate 120, although first seal ring 121 may also be disposed on opposite sides of both end plate 120 and compartment 110.

It should be noted that a gap is left between the open top of the drawer 140 and the top wall of the compartment 110, so that the air inside the drawer 140 is conveniently communicated with the chamber 1101 of the compartment 110, and the water vapor transpired from the articles inside the drawer 140 can be quickly dissipated into the chamber 1101, so as to be conveniently separated and condensed during pressurization.

In order to enhance the air circulation between the drawer 140 and the chamber 1101, as shown in fig. 3, a through hole 141 is provided on the drawer 140, and the drawer 140 is communicated with the chamber 1101 through the through hole 141. The through hole 141 may enhance the air communication between the drawer 140 and the chamber 1101, specifically, the through hole 141 may be located on the side wall 117 of the drawer 140 opposite to the end plate 120, or on the two side walls 117 adjacent to the end plate 120, and even the through hole 141 may be located on the bottom wall 116 of the drawer 140. The through hole 141 in the bottom wall 116 of the drawer 140 may not be oversized to prevent items from falling out. The number of the through holes 141 may be one, two, three, or more. The specific setting can be according to the actual conditions, and is not limited here.

In one embodiment, as shown in fig. 2 to 4, the compartment 110 includes an upper cover plate 115 and a compartment main body, the upper cover plate 115 is a top wall, the compartment main body includes a bottom wall 116, a side wall 117 connected to the bottom wall 116, and a back wall 118, the upper cover plate 115 and the compartment main body are enclosed to form the compartment 110, the upper cover plate 115, the bottom wall 116, and the side wall 117 are enclosed to form the storage opening 111, and the back wall 118 is the side wall 117 away from the side of the storage opening 111. The upper cover plate 115 is in sealing abutment with the side wall 117 and the back wall 118, and is disposed opposite to the bottom wall 116.

Because the compartment 110 is formed by enclosing the upper cover plate 115 and the compartment main body, the upper cover plate 115 is easy to disassemble, the cleaning work of the inner wall of the compartment 110 is convenient, and the split structure is beneficial to production and manufacturing.

Specifically, as shown in fig. 2 and 3, in order to enhance the sealing between the upper cover plate 115 and the chamber body, a second sealing ring 1151 is disposed between the upper cover plate 115 and the chamber body, and the second sealing ring 1151 forms a seal between the upper cover plate 115 and the top of the sidewall 117 and the top of the back wall 118 of the chamber body, so as to maintain the sealing performance of the chamber 1101 and reduce the entrance of external moisture. Specifically, the second sealing ring 1151 may be disposed on a side of the upper cover plate 115 facing the chamber body, or on a side of the chamber body facing the upper cover plate 115, but of course, the second sealing ring 1151 may also be disposed on both opposite sides of the end plate 120 and the chamber 110.

The inner wall of the refrigerator 100 is further provided with a guide 1152, and the guide 1152 supports the upper cover 115 such that the upper cover 115 can be fixed above the drawer 140.

Further, as shown in fig. 2, in the direction from the storage opening 111 to the back wall 118, the upper cover plate 115 is inclined toward the bottom wall 116, so that the condensed water drops at the upper cover plate 115 will slide down along the inclined upper cover plate 115 to the side of the upper cover plate 115 toward the bottom wall 116, and will not drop to the surface of the object. In addition, when the refrigerator 100 further includes the drawer 140, since the upper cover plate 115 is inclined toward the bottom wall 116, when the drawer 140 is outwardly drawn, a distance between the drawer 140 and the upper cover plate 115 is increased, thereby facilitating the drawing of the drawer 140. Preferably, the angle between the upper cover plate 115 and the horizontal plane is 1.5 °, and in other embodiments, the angle between the upper cover plate 115 and the horizontal plane may also be 1 °, 2 °, 2.5 °, and the like, which is not limited herein.

Due to the inclination of the upper cover plate 115, the plane of the upper edge of the drawer 140 is parallel to the side of the upper cover plate 115 facing the drawer 140, so that the upper edge of the drawer 140 is inclined toward the bottom wall 116 in cooperation with the upper cover plate 115.

In one embodiment, as shown in fig. 3, the end plate 120 is provided with a locking portion 160, the compartment 110 is provided with a locking member 150, and the locking member 150 is locked to the locking portion 160 when the drawer 140 extends into the compartment 110 from the storage opening 111 and the end plate 120 seals the storage opening 111. Therefore, the locking part 160 is connected in a locking manner to ensure that the drawer 140 is placed in place in the compartment 110, and the locking part 150 is connected in a locking manner with the locking part 160, so that the drawer 140 and the compartment 110 are completely sealed, and the drawer 140 is prevented from being pushed open when the air pump 130 is pressurized.

Specifically, as shown in fig. 5 and 6, the locking portion 160 includes an extension plate 161 connected to the end plate 120, the extension plate 161 extends toward the inner side of the chamber 1101, and a strip-shaped hole 1611 is formed in the extension plate. The locking member 150 includes a connection post 151 and a locking block 152, the connection post 151 is rotatably disposed on the upper cover plate 115 of the compartment 110, the connection post 151 can slide along a direction close to or away from the extension plate 161, the locking block 152 is connected to one end of the connection post 151 facing the extension plate 161, the length of the locking block 152 is less than or equal to the length of the strip-shaped hole 1611 and is greater than the width of the strip-shaped hole 1611, and the width of the locking block 152 is less than or equal to the width of the strip-shaped hole 1611. Therefore, after articles are placed in the drawer 140, the drawer 140 is pushed into the compartment 110, when the drawer 140 is closed to the compartment 110, the connecting column 151 is rotated, the fixture 152 is aligned with the strip-shaped hole 1611 of the extension plate 161, the width direction of the fixture 152 is aligned with the width direction of the strip-shaped hole 1611, the fixture 152 corresponds to the strip-shaped hole 1611 without interference, the connecting column 51 is moved downwards, the fixture 152 is clamped into the strip-shaped hole 1611, then the connecting column 151 is rotated by 90 degrees, the length of the fixture 152 is aligned with the width of the strip-shaped hole 1611, the fixture 152 is locked with the extension plate 161, the locking member 150 is locked with the locking portion 160, and the drawer 140 is hermetically connected with the compartment 110.

Further, as shown in fig. 5, an elastic member 153 is sleeved on the connecting column 151, one end of the elastic member 153 abuts against a step surface 1511 of the connecting column 151 far from one end of the latch 152, and the other end of the elastic member 153 abuts against an upper surface of the upper cover plate 115, so that when the drawer 140 needs to be opened, the locking portion 160 and the locking member 150 need to be unlocked, the connecting column 151 is rotated by 90 °, the width of the latch 152 is aligned with the width of the strip-shaped hole 1611, the latch 152 is moved upwards by the elastic member 153 to be separated from the strip-shaped hole 1611, the locking member 150 is unlocked and separated from the locking portion 160, and then the drawer 140 is normally pulled out.

In one embodiment, as shown in fig. 3, in order to make the drawer 140 push and pull more easily, a sliding rail 1102 is provided in the compartment 110, the drawer 140 is correspondingly provided with a pulley 142, and the pulley 142 slides along the sliding rail 1102, thereby facilitating the pushing and pulling of the drawer 140.

In one embodiment, the inner surface of the chamber 110 is made of metal and coated with a hydrophobic coating. The water vapor in the air with higher relative humidity can be pre-cooled and condensed on the metal inner surface with lower temperature, and the hydrophobic coating makes the connection force of the condensed water and the metal inner surface weaker, thereby facilitating the condensed water to be discharged from the water outlet 113.

Specifically, the inner surfaces of the side wall 117, the bottom wall 116 and the back wall 118 of the chamber main body are made of metal, so that condensed water can flow downwards along the inner surfaces of the side wall 117 and the back wall 118, or the condensed water is directly condensed on the bottom wall 116 and then discharged to the water outlet 113, and the condensed water is prevented from dripping onto the surface of an article after being condensed on the top wall (i.e., the inner surface of the upper cover plate 115). Preferably, the hydrophobic coating is coated on the surface of the metal material of the chamber, water vapor in the air can be rapidly separated out and condensed on the inner surface of the metal material of the chamber main body, and separated water drops rapidly slide off under the action of the hydrophobic coating.

In order to collect and discharge the condensed water, in one embodiment, as shown in fig. 3, the storage opening 111 is in the direction of the back wall 118, the bottom wall 116 of the compartment 110 is inclined towards the direction away from the upper cover plate 115, so that the condensed water dropping to the bottom wall 116 of the compartment 110 is collected at the side of the bottom wall 116 away from the storage opening 111 along the inclination angle of the bottom wall 116, and the condensed water is collected and is beneficial to discharge. The bottom wall 116 is formed with a water chute 119 near the back wall 118, the condensed water of the bottom wall 116 is gathered in the water chute 119, and the water chute 119 is arranged to receive more condensed water, so as to avoid the large-area accumulation of the condensed water on the bottom wall 116. In other embodiments, the bottom wall 116 is formed with a gutter 119 adjacent to the side wall 117, and water drops condensed on the side wall 117 drop into the gutter 119 and flow along the gutter 119 to the side of the bottom wall 116 adjacent to the back wall 118. Of course, the bottom wall 116 may be formed with a gutter 119 adjacent to both the side wall 117 and the back wall 118.

Since the condensed water collects at the bottom wall 116 near the back wall 118, the drain 113 is provided at the back wall 118 near the bottom wall 116, facilitating rapid drainage of the collected condensed water. Preferably, the drain port 113 may be provided at the water guide groove 119 to rapidly drain the condensed water collected in the water guide groove 119.

The air inlet 112 is disposed at the back wall 118 near the upper cover plate 115 such that the air inlet 112 is disposed away from the condensed water collected, facilitating pressurization of the chamber 1101 by the air pump 130 through the air inlet 112.

The air pump 130 is communicated with the air inlet 112 through an air inlet pipe 1121, and the air pump 130 blows air into the chamber 1101 through the air inlet pipe 1121 and the air inlet 112 to pressurize the chamber 1101; the air pump 130 communicates with the drain 113 through the drain pipe 1131, the air pump 130 pumps out the condensed water collected in the chamber 1101 through the drain pipe 1131 and the drain 113, and the air pump 130 may also discharge the air in the chamber 1101 through the drain pipe 1131 and the drain 113 to restore the air pressure in the chamber 1101 to a normal value.

Specifically, the air pump 130 may be placed in the cabin of the refrigerator, and the air inlet tube 1121 has one end connected to the air outlet of the air pump 130, passes through the foaming layer on the back of the refrigerator 100, and has the other end connected to the air inlet 112 of the compartment 110. One end of the drain pipe 1131 is connected to the air inlet of the air pump 130, passes through the rear foam layer of the refrigerator 100, and the other end is connected to the drain port 113 of the compartment 110. The air pump 130 is further provided with a water outlet pipe 131 for discharging the condensed water pumped out of the chamber 1101.

Different articles are stored in the compartment 110, and the humidity of the compartment 110 to be controlled is different, that is, each article corresponds to a preset humidity. The preset humidity is a critical humidity value suitable for storing the articles, and when the current humidity is higher than the preset humidity, the articles are easy to be damaged. The preset air pressure is a critical air pressure value at which water vapor begins to separate out and condense. When the humidity sensor 180 detects that the current humidity of the chamber 1101 in the compartment 110 reaches the preset humidity, the air pump 130 pressurizes the chamber 1101, the pressure sensor 170 detects that the pressure of the chamber 1101 reaches the preset pressure, the relative humidity in the chamber 1101 reaches 100%, moisture is separated out from the air in the chamber 1101 and is condensed, the water after condensation can be pumped out by the water outlet 113 of the air pump 130, so that the humidity in the chamber 1101 is reduced, the air pressure of the compartment 110 is reduced to the normal air pressure value before pressurization, and food in the chamber 1101 is prevented from being moistened or rotten due to condensation, so that the purposes of dehumidification and drying are achieved.

Referring to fig. 7, another embodiment of the present application provides a humidity control method, including the following steps:

s101: the current humidity in the refrigerator compartment is obtained.

The current humidity of the refrigerator compartment is obtained, and the current humidity of the refrigerator compartment can be detected and obtained by a humidity sensor arranged in the refrigerator compartment.

S102: and in response to the current humidity being greater than the preset humidity, pressurizing the refrigerator compartment to a preset air pressure and maintaining the preset air pressure for a preset time.

The preset humidity is a critical humidity value suitable for storing the articles, and when the current humidity is higher than the preset humidity, the articles are easy to be damaged. The preset air pressure is a critical air pressure value at which water vapor begins to separate out and condense.

Responding to the fact that the current humidity is larger than the preset humidity, the critical value of the humidity of the articles, which is prone to condensation, is reached, the refrigerator chamber is pressurized to the preset air pressure through the air pump, the relative humidity of the air in the chamber rises until 100%, and water vapor contained in the air begins to separate out and condense. Because the water vapor in the air needs to be continuously separated out, the preset pressure needs to be maintained for the preset time, or pressurization can be continuously performed, so that the pressure of the chamber is greater than the preset pressure and the preset time is maintained, and the preset time can be set according to an actual experience value, such as 3min, 5min and the like. And when the pressurization is continued for a preset time, the water vapor is basically separated out and condensed.

The type of the articles stored in the refrigerator compartment corresponds to different preset humidity and preset air pressure, and the preset air pressure is related to the preset humidity. To facilitate control of the refrigerator compartment, it is preferable that an article having the same or similar predetermined humidity be stored in the refrigerator compartment requiring humidity control.

In one embodiment, the humidity control method further comprises: and receiving a modification instruction of the preset humidity, and storing the modified preset humidity.

Specifically, the preset humidity and the preset air pressure currently set in the refrigerator compartment can be automatically generated after a user selects a storage type on the control panel; or the user refers to a pre-provided retrieval catalog and then manually inputs the retrieval catalog, wherein the manual input can be that the preset humidity is selected on a control panel of the refrigerator through a key or can be remotely input through a mobile phone APP and the like; of course, the refrigerator compartment can also automatically detect and identify stored articles and automatically adjust according to the identified articles.

If the placed objects are dry fruits/tea leaves and the like, the value of the preset humidity can be selected to be 45%, the value of the preset humidity of fruits with skins such as apples/oranges and the like can be selected to be 75%, and the value of the preset humidity of leafy vegetables such as spinach/celery and the like can be selected to be 95%. And the value of the preset humidity is required to be below 98%, and the preset humidity higher than 98% is close to the condensation point of 100%, so that the control difficulty is high, the phenomenon that condensation occurs but dehumidification does not occur easily, and the articles are easy to damage, and the value of the preset humidity is set to be below 98%, thereby being beneficial to humidity control.

The range of the preset pressure can be calculated according to the formula d 0.622 a 1P/(X1-a 1P), where (d is the moisture content calculated in the initial state of the drawer, P is the saturated vapor pressure, which can be obtained by querying a saturated humid air table, a1 is the preset humidity, and X1 is the preset pressure).

The value of d is calculated as follows: the humidity value under the initial state of the drawer is measured, namely the A1 value at the moment, P can be obtained by inquiring a saturated humid air meter through the humidity value under the initial state of the drawer and the current temperature value, and the value of X1 is the normal pressure at the moment and can be 0.1MPa, so that the d value can be calculated.

When the preset pressure X1 corresponding to the preset humidity a1 is subsequently calculated, the saturated vapor pressure P can be obtained by looking up a table according to the preset humidity a1 value and the current temperature value (since the change between the temperature in the drawer and the temperature in the initial state is small and negligible, the temperature in the initial state can be directly used for query, and certainly, the temperature can be obtained again), so that the preset pressure X1 can be calculated.

Several specific examples are now given: the preset pressure is 0.22MPa when the preset humidity is 45%, the preset pressure is 0.135MPa when the preset humidity is 75%, and the preset pressure is 0.107MPa when the preset humidity is 95%.

S103: the condensed water in the refrigerator compartment is extracted.

Because the water vapor is separated out and condensed, the condensed water can be pumped out, thereby reducing the humidity in the cavity and avoiding the food in the cavity from being damped or rotten due to condensation. Because the cavity passes through the in-process of outlet drainage, the air pressure in the cavity is also reducing, and the condensate water easily gives off to the air once more, and can take out the condensate water fast through the air pump, reduces the steam in the air of giving off once more, and the at utmost reduces the humidity of room.

S104: the refrigerator compartment was depressurized to atmospheric pressure.

After the air pump pumps out the condensed water, the air pump can continue to pump out and reduce the pressure of the refrigerator chamber, so that the pressure in the chamber is recovered to a normal air pressure value, and a user can open the drawer conveniently.

The humidity control method of the present application can be used for humidity control of the refrigerator of any of the above embodiments.
