Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the 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. Wherein the compartment 110 is formed with a chamber 1101 for placing articles, and also formed with a storage port 111, an air inlet 112, and a water outlet 113 communicating with the chamber 1101. The end plate 120 is movably disposed with respect to the compartment 110 to open or seal the storage opening 111, and when the end plate 120 is sealed at the storage opening 111, the chamber 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 chamber 1101 with the outside for the insertion or removal of articles. 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 charge air and pressurize the chamber 1101 through the air inlet 112, the water outlet 113 can discharge the condensed water in the chamber 1101, and the humidity of the chamber 1101 is reduced.

Because the sealed state cannot be maintained in the chamber 1101 at any time, when an article needs to be taken out or put in through the storage port 111, air invasion outside the chamber 1101 may cause an increase in relative humidity in the chamber 1101; alternatively, the moisture content in the chamber 1101 increases due to the phenomenon of transpiration of high-moisture foods such as fruits and vegetables stored in the chamber 1101. In the refrigerator 100 of the present application, when the end plate 120 is sealed and arranged 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 unchanged, the air pump 130 inflates the chamber 1101 through the air inlet 112, the pressure in the chamber 1101 is increased, so that excessive moisture on the articles and condensation on the surfaces of the articles are dispersed into the air, the relative humidity of the air is increased, when the pressure is increased to a certain degree, the relative humidity reaches 100%, the moisture is separated from the air in the chamber 1101 and condensed, the water after condensation can be pumped out by the water outlet 113 of the air pump 130, the humidity in the chamber 1101 is reduced, and the food in the chamber 1101 is prevented 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 drain port 113, the condensed water is easy to be diffused into the air again, and the condensed water can be rapidly pumped out through the air pump 130, so that the water vapor in the air is reduced to be diffused again, and the humidity of the chamber 1101 is reduced to the greatest extent. When the air pump 130 pumps out the condensed water, the condensed water can be continuously pumped out and decompressed through the water outlet 113, so that the pressure in the chamber 1101 is restored to the normal air pressure value, and the drawer 140 is convenient for a user to open.

As shown in fig. 1, the compartment 110 may be provided in a refrigerating chamber of the refrigerator 100, and when the refrigerator 100 is normally refrigerating, the compartment 110 is sealed, and wind of 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 opened to place or take an item, air from the refrigerated compartment enters chamber 1101, which is typically at a higher humidity, so that air that enters chamber 1101 will cause the relative humidity within chamber 1101 to increase. In addition, the chamber 1101 is a relatively sealed space, and the relative humidity in the chamber 1101 is increased due to the fact that the placed articles continuously emit water vapor under the action of transpiration, and if the placed articles are fruits and vegetables, the relative humidity may reach 100% under the action of transpiration, and the air pump 130 is required to operate to regulate the humidity.

Alternatively, compartment 110 may be a separate refrigerator compartment. Both the intrusion of air outside the chamber 1101 and the transpiration of the items stored within the chamber 1101 can result in an increased 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 pulled out of the compartment 110 from the storage opening 111. The drawer 140 is movably arranged in the compartment 110, and when articles are required to be placed in the compartment 110 or taken out, the drawer 140 can be taken out of the compartment 110, so that articles can be conveniently arranged and put in, and the articles can be conveniently turned over and taken out. 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 separated and condensed, 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, and the articles are protected, so that the 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 damped or spoiled.

In order to enhance the sealing of the end plate 120 with the compartment 110, as shown in fig. 2 to 4, a first sealing ring 121 is provided between the end plate 120 and the compartment 110, and the first sealing ring 121 forms a seal between the end plate 120 and the top, side and bottom walls 117, 116 of the compartment 110, thereby maintaining the sealing of the chamber 1101 and reducing the ingress of external moisture. Specifically, the first seal ring 121 may be disposed on the side of the end plate 120 facing the chamber 110, or on the side of the chamber 110 facing the end plate 120, although the first seal ring 121 may be disposed on opposite sides of both the end plate 120 and the chamber 110.

It should be noted that, a gap is left between the top opening of the drawer 140 and the top wall of the compartment 110, so that the air inside the drawer 140 is conveniently conducted with the chamber 1101 of the compartment 110, and the vapor evaporated from the articles in the drawer 140 can be quickly emitted into the chamber 1101, so that the vapor can be conveniently separated out and condensed during pressurization.

In order to enhance the air communication between the drawer 140 and the chamber 1101, as shown in fig. 3, a through hole 141 is provided in the drawer 140, and the drawer 140 is in communication with the chamber 1101 through the through hole 141. The through holes 141 may enhance the air communication of the drawer 140 with the chamber 1101, and in particular, the through holes 141 may be located on the side wall 117 of the drawer 140 opposite to the end plate 120, or on both side walls 117 adjacent to the end plate 120 side, or even the through holes 141 may be located on the bottom wall 116 of the drawer 140. The through holes 141 in the bottom wall 116 of the drawer 140 cannot be oversized to prevent items from falling out. The number of the through holes 141 may be one, two, three, or more. Specifically, the method can be set according to practical situations, and is not limited herein.

In an embodiment, as shown in fig. 2 to 4, the chamber 110 includes an upper cover 115 and a chamber body, the upper cover 115 is a top wall, the chamber body includes a bottom wall 116, a side wall 117 and a back wall 118 connected to the bottom wall 116, the upper cover 115 and the chamber body enclose the chamber 110, the upper cover 115, the bottom wall 116 and the side wall 117 enclose the storage opening 111, and the back wall 118 is a side wall 117 far away from one side of the storage opening 111. The upper cover plate 115 is in sealing contact 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 closing the upper cover plate 115 and the compartment main body, the upper cover plate 115 is easy to detach, the cleaning work on the inner wall of the compartment 110 is convenient, and the split structure is beneficial to production and manufacture.

Specifically, as shown in fig. 2 and 3, in order to enhance the sealing of the upper cover plate 115 with the chamber body, a second sealing ring 1151 is provided 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 side wall 117 and the top of the back wall 118 of the chamber body, thereby maintaining the sealing of the chamber 1101 and reducing the entry of external moisture. Specifically, the second seal 1151 may be disposed on the side of the upper cover plate 115 facing the chamber body, or on the side of the chamber body facing the upper cover plate 115, although the second seal 1151 may be disposed on opposite sides of the end plate 120 and the chamber 110.

The inner wall of the refrigerator 100 is further provided with a guide rail 1152, and the guide rail 1152 supports the upper cover plate 115 so that the upper cover plate 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 along the inclined upper cover plate 115 to the side of the upper cover plate 115 toward the bottom wall 116, and avoid dropping to the surface of the article. In addition, when the refrigerator 100 further includes the drawer 140, since the upper cover plate 115 is inclined toward the bottom wall 116, the distance between the drawer 140 and the upper cover plate 115 becomes greater when the drawer 140 is drawn out, so that the drawer 140 is easily drawn out. Preferably, the upper cover plate 115 forms an angle of 1.5 ° with the horizontal plane, and in other embodiments, the upper cover plate 115 may also form an angle of 1 °, 2 °, 2.5 ° with the horizontal plane, and the like, which is not limited herein.

Because the upper cover plate 115 is inclined, the plane of the upper edge of the drawer 140 is parallel to the side surface 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 when the drawer 140 extends into the compartment 110 from the storage opening 111, the locking member 150 is locked and connected to the locking portion 160 when the end plate 120 seals the storage opening 111. Therefore, the drawer 140 can be determined to be placed in place in the compartment 110 through the locking connection locking part 160, and the locking piece 150 is in locking connection with the locking part 160, so that the drawer 140 and the compartment 110 can be completely sealed, and the drawer 140 is prevented from being flushed 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 one side in the chamber 1101, and a strip-shaped hole 1611 is formed in the extension plate. The locking member 150 includes a connecting post 151 and a clamping block 152, the connecting post 151 is rotatably disposed on the upper cover plate 115 of the chamber 110, and the connecting post 151 can slide along a direction close to or far away from the extending plate 161, the clamping block 152 is connected to one end of the connecting post 151 facing the extending plate 161, the length of the clamping block 152 is smaller than or equal to the length of the bar-shaped hole 1611, and is larger than the width of the bar-shaped hole 1611, and the width of the clamping block 152 is smaller than or equal to the width of the bar-shaped hole 1611. Thus, after the 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 so that the clamping blocks 152 are aligned with the strip-shaped holes 1611 of the extension plate 161, the width direction of the clamping blocks 152 are aligned with the width direction of the strip-shaped holes 1611, the clamping blocks 152 are corresponding to the strip-shaped holes 1611 without interference, the connecting column 51 is moved downwards, the clamping blocks 152 are clamped into the strip-shaped holes 1611, then the connecting column 151 is rotated by 90 degrees so that the lengths of the clamping blocks 152 are aligned with the width of the strip-shaped holes 1611, the clamping blocks 152 are locked with the extension plate 161, the locking pieces 150 are locked with the locking parts 160, and the drawer 140 is in sealing connection with the compartment 110.

Further, as shown in fig. 5, an elastic member 153 is sleeved on the connection post 151, one end of the elastic member 153 abuts against a step surface 1511 of the connection post 151 far away from one end of the clamping block 152, and the other end of the elastic member 153 abuts against the upper surface of the upper cover plate 115, so that when the drawer 140 needs to be opened, the locking part 160 and the locking member 150 need to be unlocked, the connection post 151 is rotated by 90 ° to align the width of the clamping block 152 with the width of the bar-shaped hole 1611, the elastic member 153 enables the clamping block 152 to move upwards to be separated from the bar-shaped hole 1611, and then the locking member 150 is unlocked and separated from the locking part 160, and the drawer 140 is normally pulled out.

In one embodiment, as shown in fig. 3, in order to make the drawer 140 easily pushed and pulled, a sliding rail 1102 is provided in the compartment 110, and the drawer 140 is correspondingly provided with a pulley 142, and the pulley 142 slides along the sliding rail 1102, so that the drawer 140 can be pushed and pulled out conveniently.

In one embodiment, the inner surface of the chamber 110 is metallic and is coated with a hydrophobic coating. The water vapor in the air with higher relative humidity can be pre-condensed at the inner surface of the metal with lower temperature, and the hydrophobic coating can make the connection force between the condensed water and the inner surface of the metal weaker, so that the condensed water is favorably discharged from the water outlet 113.

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

In order to collect and drain the condensed water conveniently, in an embodiment, as shown in fig. 3, in the direction from the storage opening 111 to the back wall 118, the bottom wall 116 of the chamber 110 is inclined towards the direction away from the upper cover plate 115, so that the condensed water dropped to the bottom wall 116 of the chamber 110 is collected on 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 convenient to drain. The bottom wall 116 is formed with a water guide groove 119 near the back wall 118, the condensed water of the bottom wall 116 is converged in the water guide groove 119, and the water guide groove 119 can be used for receiving more condensed water, so that the condensed water is prevented from being accumulated in a large area of the bottom wall 116. In other embodiments, the bottom wall 116 is formed with a water guiding groove 119 near the side wall 117, and the water droplets condensed on the side wall 117 drop into the water guiding groove 119 and flow along the water guiding groove 119 to the side of the bottom wall 116 near the back wall 118. Of course, the bottom wall 116 may be formed with a water guide groove 119 near both the side wall 117 and the back wall 118.

Since the condensed water is collected at the bottom wall 116 near the back wall 118, the drain port 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 119, and may rapidly drain the condensed water collected in the water guide 119.

The air inlet 112 is disposed on the back wall 118 proximate the upper cover plate 115 such that the air inlet 112 is disposed away from the accumulated condensate water to facilitate pressurization of the air pump 130 into the chamber 1101 through the air inlet 112.

The air pump 130 is communicated with the air inlet 112 through the air inlet pipe 1121, and the air pump 130 introduces 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 is communicated with the drain port 113 through a drain pipe 1131, the air pump 130 pumps out condensed water accumulated in the chamber 1101 through the drain pipe 1131 and the drain port 113, and the air pump 130 can also drain out air in the chamber 1101 through the drain pipe 1131 and the drain port 113 to restore the air pressure in the chamber 1101 to a normal value.

Specifically, the air pump 130 may be placed in the press cabin, and the air inlet pipe 1121 has one end connected to the air outlet of the air pump 130 and the other end connected to the air inlet 112 of the compartment 110 after passing through the back foaming layer of the refrigerator 100. The drain pipe 1131 has one end connected to the suction port of the air pump 130, and the other end connected to the drain port 113 of the compartment 110 after passing through the back foaming layer of the refrigerator 100. The air pump 130 is further provided with a water outlet pipe 131 to discharge condensed water drawn out from the chamber 1101.

In one embodiment, as shown in fig. 4, a pressure sensor 170 and a humidity sensor 180 are provided in the chamber 110, the pressure sensor 170 detects the pressure in the chamber 110, and the humidity sensor 180 detects the humidity in the chamber 110.

Different articles are stored in the compartments 110, and the humidity of the compartments 110 to be controlled is different, i.e. each article corresponds to a preset humidity. The preset humidity is a humidity critical value for proper storage of the article, and when the current humidity is higher than the preset humidity, the article is easy to damage. The preset air pressure is a critical air pressure value at which water vapor begins to precipitate 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%, water is separated from air in the chamber 1101 and 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 a normal air pressure value before pressurization, and food in the chamber 1101 is prevented from being wetted or rotten due to condensation, so that the aim of dehumidifying and drying is fulfilled.

Referring to fig. 7, a humidity control method according to another embodiment of the present application includes 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 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 refrigerator compartment for a preset time.

The preset humidity is a humidity critical value for proper storage of the article, and when the current humidity is higher than the preset humidity, the article is easy to damage. The preset air pressure is a critical air pressure value at which water vapor begins to precipitate and condense.

And responding to the fact that the current humidity is greater than the preset humidity, indicating that the humidity critical value of the articles which are easy to be condensed is reached, pressurizing the refrigerator compartment to the preset air pressure through the air pump, and rising the relative humidity of air in the compartment until the relative humidity is 100%, wherein water vapor contained in the air begins to be separated out and condensed. The vapor in the air needs to be continuously separated out, and the preset pressure needs to be maintained for a preset time, or the pressurization can be continuously performed, so that the pressure of the chamber is higher than the preset pressure and the preset time is maintained, and the preset time can be set according to practical experience values, such as 3min, 5min and the like. After continuing to pressurize for a preset time, the water vapor is basically separated out and condensed.

The types of articles stored in the refrigerator compartment correspond to different preset humidity and preset air pressure, and the preset air pressure is related to the preset humidity. In order to facilitate control of the refrigerator compartments, it is preferable that a refrigerator compartment requiring humidity control stores articles having the same or similar preset humidity.

In an 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 preset air pressure currently set in the refrigerator compartment may be automatically generated after a user selects a storage type on the control panel; or the user refers to a preset index list and then manually inputs the index list, wherein the manual input can be that the preset humidity is selected through keys on a control panel of the refrigerator, or the preset humidity can be input through remote control such as a mobile phone APP; of course, the refrigerator compartment can also automatically detect and identify stored articles, and automatically adjust according to the identified articles.

If the placed articles are dried fruits/tea leaves and the like, the preset humidity value can be 45%, the apple/orange peel fruits and the like, the preset humidity value can be 75%, the spinach/celery leafy vegetables and the like, and the preset humidity value can be 95%. In addition, the preset humidity value is required to be below 98%, and as the preset humidity higher than 98% is close to the 100% condensation point, the control difficulty is high, the phenomenon that condensation is generated and dehumidification is not performed easily occurs, and the articles are easy to damage, so that the preset humidity value is set below 98%, and the humidity control can be facilitated.

The range of the preset pressure can be calculated according to the formula d=0.622×a1×p/(X1-a 1×p), where (d is the moisture content calculated in the initial state of the drawer, P is the saturated vapor pressure, and can be obtained by querying a saturated wet air meter, A1 is the preset humidity, and X1 is the preset pressure).

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

When the preset pressure X1 corresponding to the preset humidity A1 is calculated later, 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 (because the change between the temperature in the drawer and the temperature in the initial state is smaller and negligible, the temperature in the initial state can be directly used for inquiring, and the temperature can be obtained again), so that the preset pressure X1 can be calculated and obtained.

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

S103: condensed water in the refrigerator compartment is drawn out.

After the water vapor is separated out and condensed, the condensed water can be pumped out, so that the humidity in the cavity is reduced, and the food in the cavity is prevented from being wetted or rotted due to condensation. Because the air pressure in the cavity is also being reduced through the in-process of outlet drainage in the cavity, the condensate water is easy to give off to the air again, and can be taken out fast through the air pump, reduce and give off the steam in the air once more, the maximum humidity that will be in the room reduces.

S104: the refrigerator compartment was depressurized to normal pressure.

When the air pump pumps out the condensed water, the condensed water can be continuously pumped out and decompressed through the refrigerator compartment, so that the pressure in the cavity is restored to the normal air pressure value, and the drawer can be conveniently opened by a user.

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