Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0073] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments.

It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0074] In order to solve the technical problem in the prior art that the dry area and the wet area are two independent spaces, their humidity adjustment modules are generally independent of each other, the two modules cannot be combined, and resource utilization is not maximized, the present disclosure provides a humidity adjustment device, a refrigerator and a humidity adjustment method.

[0075] Among them, in the present disclosure, a humidity control space is newly added, and the humidity control space is connected to the dry space and the wet space respectively, and a first drying device is arranged in the dry space to diffuse the moisture of the items placed in the dry space to the dry space. In addition, the humidity control space of the present disclosure is provided with a humidity control module. When the dry space has a drying demand, the first drying device diffuses the moisture of the items placed in the dry space to the dry space, and then the humidity control module can absorb the moisture in the dry space, thereby achieving drying of the dry space and better preserving the items placed in the dry space. When the wet space has a humidification demand, the humidity control module can release moisture to the wet space, thereby increasing the humidity of the wet space. In other words, the humidity control module can release the moisture absorbed from the dry space to the wet space, realize the linkage between the dry space and the wet space, maximize resource utilization, and save energy consumption. Moreover, since the present invention can actively humidify the wet space, compared with the gas regulating membrane solution in the related art, the present invention can achieve a better preservation effect even when fewer items are placed in the wet space, and better avoid the phenomenon of wilting and water loss of items placed in the wet space.

[0076] In an exemplary embodiment, a humidity adjustment device and a humidity adjustment method thereof are provided. Figure 1 and Figure 2 As shown, the humidity regulating device includes a wet area space 10, a dry area space 30 and a humidity regulating space 20. The wet area space 10 is used to store items that require higher humidity, such as vegetables, and the dry area space 30 is used to store items that require lower humidity, such as dry goods, and the humidity regulating space 20 plays a role in regulating the humidity of the two areas.

[0077] The humidity-controlled space 20 is connected to the wet space 10 , and the humidity-controlled space 20 is connected to the dry space 30 . The dry space 30 includes a first drying device 31 , which is used to diffuse the moisture of the items placed in the dry space 30 to the dry space 30 .

[0078] The first drying device 31 may include a first far-infrared drying device. The wavelength range of far-infrared rays is 25-1000 μm. When the objects placed in the drying space 30 (such as dried vegetables such as white fungus, black fungus, and bean curd sticks) absorb infrared rays, almost no chemical changes occur. Only the particles are aggravated to move, causing the temperature of the objects to rise. In particular, when the molecules and atoms of the objects encounter radiation with a radiation frequency consistent with their inherent frequency, a similar resonance situation will occur, thereby causing the objects to heat up and dry. In the process of drying by infrared radiation, since infrared rays have a certain degree of penetration, heat accumulation is formed inside the objects. In addition, the moisture on the surface of the dried objects evaporates and absorbs heat continuously, causing the surface temperature of the objects to decrease, resulting in a higher temperature inside the objects than outside, so that the heat diffusion process of the objects is carried out from the inside to the outside. At the same time, since the moisture movement caused by the moisture gradient inside the objects is always from the inside with more moisture to the outside with less moisture, the wet diffusion of the moisture inside the objects is consistent with the heat diffusion direction, which will accelerate the diffusion process of the moisture, that is, accelerate the drying process.

[0079] It should be noted that the first drying device 31 may be not only a far-infrared drying device but also other drying devices, without limitation, as long as it can diffuse the moisture of the items placed in the dry space 30 into the dry space 30 .

[0080] In this embodiment, the humidity control space 20 includes a humidity control module 21, which is configured to absorb moisture from the dry space 30 when the dry space 30 needs to be dried, and release moisture to the wet space 10 when the wet space 10 needs to be humidified.

[0081] The humidity control module 21 may include a water-absorbing material that can absorb and release water. The water-absorbing material may be, for example, a high molecular weight polymer with a relatively large molecular weight, high hydrophilicity, and good water storage performance, such as N-isopropylacrylamide. When its temperature is lower than the critical temperature, the molecule is helical and hydrophilic, that is, it has good hygroscopic performance; when its temperature exceeds the critical temperature, it changes from hydrophilic to hydrophobic, and may be accompanied by structural contraction, and the molecular form becomes a small spherical shape, and the adsorbed water molecules can be released by squeezing to achieve the effect of "automatic water release".

[0082] It should be noted that the water-absorbing material may be, in addition to the above-mentioned materials, other materials that can switch between hydrophilicity and hydrophobicity, and this is not limited.

[0083] In which, the humidity regulating device of this embodiment may include a control device. When the control device determines that the dry space 30 has a drying demand, it can control the first drying device 31 to turn on, and control the humidity regulating space 20 to absorb moisture from the dry space 30; when the control device determines that the wet space 10 has a humidification demand, it can control the humidity regulating space 20 to release moisture to the wet space 10 to humidify the wet space 10.

[0084] Compared with the related art, this embodiment adds a humidity control space 20, and connects the humidity control space 20 with the dry space 30 and the wet space 10, respectively, so as to realize the linkage between the wet space 10 and the dry space 30. In addition, a first drying device 31 is provided in the dry space 30, which is used to diffuse the moisture of the items placed in the dry space 30 to the dry space 30. In addition, the humidity control module 21 is provided in the humidity control space 20 of this embodiment. When the dry space 30 has a drying requirement, the first drying device 31 diffuses the moisture of the items placed in the dry space 30 to the dry space 30, and then the humidity control module 21 can absorb the moisture in the dry space 30, so as to realize the drying of the dry space 30 and better preserve the items placed in the dry space 30. When the wet space 10 has a drying requirement, the humidity control module 21 can release moisture to the wet space 10, so as to increase the humidity of the wet space 10.

[0085] That is to say, the humidity control module 21 can release the moisture absorbed from the dry space 30 to the wet space 10, realize the linkage between the dry space 30 and the wet space 10, realize the maximum resource utilization, and save energy consumption. Moreover, since this embodiment can actively humidify the wet space 10 through the humidity control module 21, compared with the solution of the gas regulating membrane in the related art, even when there are fewer items placed in the wet space 10, the solution of this embodiment can also achieve a better preservation effect, and better avoid the phenomenon of wilting and water loss of the items placed in the wet space 10.

[0086] In an exemplary embodiment, a humidity adjustment device and a humidity adjustment method are provided. Figures 1 to 4 As shown, the humidity conditioning space 20 may include a dehumidification channel, one end of which is connected to the humidity conditioning module 21, and the other end of which is connected to the dry space 30 through a dehumidification hole (not shown in the figure). That is, the humidity conditioning module 21 is connected to the dry space 30 through the dehumidification channel.

[0087] The dehumidification channel may include a first control valve 221 and a first fan 222, and the first control valve 221 is used to control the dehumidification channel to be turned on or off. The first fan 222 is located at the location of the dehumidification hole, and the first fan 222 is used to move the gas in the dehumidification channel from the dehumidification hole toward the humidity control module 21. In addition, the humidity control space 20 also includes an exhaust channel connected to the humidity control module 21, and the exhaust channel includes a second control valve 231, and the second control valve 231 is used to control the exhaust channel to be turned on or off.

[0088] In this embodiment, when it is necessary to control the humidity control space 20 to absorb moisture from the dry space 30, the control device can open the first control valve 221, the second control valve 231 and the first fan 222. The first fan 222 transports the gas in the dry space 30 to the location of the humidity control module 21 through the dehumidification channel. After the humidity control module 21 absorbs the moisture in the gas, it is discharged to the outside of the humidity control device through the exhaust channel, thereby achieving a drying effect on the dry space 30, and the moisture in the dry space 30 can be stored in the humidity control module 21 for later use.

[0089] The dehumidification channel may include a first humidity detection device 223, and the first humidity detection device 223 is located between the first control valve 221 and the dehumidification hole. The first humidity detection device 223 may be, for example, a humidity sensor, which may be used to detect the humidity of the gas on the side of the dehumidification channel close to the dry space 30. It should be noted that since the first humidity detection device 223 is located between the first control valve 221 and the dehumidification hole, that is, the first humidity detection device 223 is located on the side of the first control valve 221 close to the dry space 30, the position of the first humidity detection device 223 is always connected to the dry space 30, and the humidity detected by the first humidity detection device 223 may be considered as the humidity of the dry space 30.

[0090] In this embodiment, the humidity value detected by the first humidity detection device 223 can be transmitted to the control device. When the control device determines that the humidity value detected by the first humidity detection device 223 is greater than the first humidity threshold, it indicates that the dry area space 30 may have a drying requirement. It should be noted that the first humidity threshold can be set according to actual needs, and its specific value may not be limited. For example, the first humidity threshold can be 90%.

[0091] When the humidity of the dry space 30 is high, there is no need to dry the dry space 30 if there is no object placed in the dry space 30. That is, when determining whether the dry space 30 has a drying requirement, this embodiment needs to determine whether there is an object placed in the dry space 30.

[0092] The dry space 30 may further include a distance detection device 32, which may be disposed at the top of the dry space 30. The distance detection device 32 may use technologies such as ultrasonic sensors and laser sensors to detect the distance between it and the bottom of the dry space 30. When the distance value detected by the distance detection device 32 is equal to the distance between the distance detection device 32 and the bottom of the dry space 30, it indicates that no items are placed in the dry space 30. When the distance value detected by the distance detection device 32 is less than the distance between the distance detection device 32 and the bottom of the dry space 30, it indicates that there are items placed in the dry space 30.

[0093] That is to say, in this embodiment, if the control device determines that the humidity value detected by the first humidity detection device 223 is greater than the first humidity threshold, and determines that the distance value detected by the distance detection device 32 is less than the distance between the distance detection device 32 and the bottom of the dry space 30, it means that the dry space 30 has a drying requirement, and the first control valve 221, the second control valve 231 and the first fan 222 can be opened to dry the dry space 30.

[0094] Among them, the first drying device 31 may include a plurality of first far-infrared drying devices evenly distributed along the top surface of the dry area space 30, and the first far-infrared drying devices extend from the entrance of the dry area space 30 toward a direction away from the entrance. Through the above arrangement, the items placed in the dry area space 30 can be evenly heated and dried.

[0095] The first drying device 31 may include a plurality of distance detection devices 32, and the plurality of distance detection devices 32 correspond to the plurality of first far-infrared drying devices one by one. In the mutually corresponding distance detection devices 32 and the first far-infrared drying devices, the distance detection devices 32 are located in the middle of the extension direction of the first far-infrared drying devices, so that the number of items placed in the drying space 30 can be determined more accurately.

[0096] In this embodiment, when determining whether there is an object placed in the dry space 30, if the distance value detected by at least one of the multiple distance detection devices 32 is smaller than the distance between the distance detection device 32 and the bottom of the dry space 30, it indicates that there is an object placed in the dry space 30.

[0097] In this embodiment, the control device can adjust the working intensity and time of the first far-infrared drying device according to the location and quantity of the placed objects to achieve the best drying effect.

[0098] For example, the ratio of the items placed in the dry space 30 to the volume of the dry space 30 can be determined based on the size of the shelf in the dry space 30 and the distance values ​​detected by the multiple distance detection devices 32. Then, the opening time of the first far-infrared drying device is controlled based on the ratio to achieve a better drying effect.

[0099] It should be noted that the first drying device 31 may include a plurality of first far-infrared drying devices evenly distributed along the top surface of the dry space 30, and a distance detection device 32 is arranged in the middle position of each first far-infrared drying device to facilitate more accurate determination of the ratio of the items placed in the dry space 30 to the volume of the dry space 30.

[0100] Among them, the storage rack in each dry space 30 has a fixed length L0 and width W0, and the distance between the storage rack at the bottom and the top of the dry space 30 can be recorded as H0. In this embodiment, the total available volume V0 in the dry space 30 can be calculated based on H0, L0 and W0. When there are items placed in the dry space 30, assuming that the dimension in the depth direction of the placed items is equal to W0, the maximum size Hmax of the placed items is calculated based on the minimum value Hmin of the measured distance of the distance detection device 32 on the first far-infrared drying device distributed at equal intervals, and then the occupied volume V of the placed items can be approximately calculated. If the ratio of the occupied volume V to the total available volume V0 is R∈(0,25%), the first far-infrared drying device is controlled to be turned on for t1; if the ratio is R∈[25,50%), the first far-infrared drying device is controlled to be turned on for t2; if the ratio is R∈[50,75%), the first far-infrared drying device is controlled to be turned on for t3. Wherein t3>t2>t1, the values ​​of L0, H0 and W0 are determined according to actual conditions and are not limited thereto.

[0101] For example, L0=35cm, W0=25cm, H0=30cm, and the total available volume of the dry storage space is 26.25L. According to the height dimension Hmax=10cm of the items placed in the dry space 30 detected by the distance detection device 32, the length of the items is between the second and fifth first far-infrared drying devices, so L=L0*4 / 7=20cm, the width is W0=25cm, and the occupied volume V=5L of the placed items is obtained. Based on this, the proportion R=19% can be calculated. Therefore, the first far-infrared drying devices at the second, third, fourth and fifth positions are turned on, and the opening time is t1.

[0102] In the related art, the dry space is mostly dehumidified and dried by dry air passing through the evaporator of the freezing chamber, which cannot effectively solve the problem of moisture or mold on dry goods. In this embodiment, through the cooperation between the first far-infrared drying device, the distance detection device 32 and the humidity control space 20, the drying effect of the dry space 30 can be better achieved to solve the problem of moisture or mold on the items placed in the dry space 30.

[0103] In an exemplary embodiment, a humidity adjustment device and a humidity adjustment method are provided. Figures 1 to 9 As shown, the humidity control space 20 may include a humidification channel connected to the humidity control module 21, and the humidification channel is connected to the wet area space 10 through the humidification hole 245. In addition, the humidification channel includes a third control valve 241 and a second fan 242, and the third control valve 241 is used to control the humidification channel to be turned on or off. For example, when the wet area space 10 needs to be humidified, the third control valve 241 is opened to turn on the humidification channel; when humidification is not required, the third control valve 241 is closed to cut off the humidification channel.

[0104] The second fan 242 is located at the position of the humidification hole 245 , and is used to move the gas in the humidification channel from the humidity control module 21 toward the humidification hole 245 , thereby transporting the moisture released by the humidity control module 21 to the wet zone space 10 .

[0105] The humidity control space 20 may include a second far-infrared drying device 25, which adjusts the performance of the water-absorbing material by adjusting the temperature of the water-absorbing material. For example, when it is determined that the wet space 10 has a humidification demand, the second far-infrared drying device 25, the third control valve 241 and the second fan 242 may be turned on to increase the temperature of the water-absorbing material, so that the water-absorbing material is in a hydrophobic state, and releases moisture to the humidity control space 20, and the second fan 242 transmits it to the wet space 10 through the humidification channel to humidify the wet space 10.

[0106] In this embodiment, the humidification channel may include a third humidity detection device 243 (e.g., a humidity sensor). The third humidity detection device 243 is located between the humidification hole 245 and the third control valve 241, and can be used to detect the humidity of the gas on the side close to the wet zone space 10 in the humidification channel. It should be noted that since the third humidity detection device 243 is located between the third control valve 241 and the humidification hole 245, that is, the third humidity detection device 243 is located on the side of the third control valve 241 close to the wet zone space 10, the position where the third humidity detection device 243 is located is always connected to the wet zone space 10, and the humidity detected by it can be considered as the humidity of the wet zone space 10.

[0107] Among them, the humidity value detected by the third humidity detection device 243 can be transmitted to the control device. When the control device determines that the above humidity value is less than the first humidity threshold, it can determine that the wet area space 10 has a humidification demand, and can turn on the second far-infrared drying device 25, the third control valve 241 and the second fan 242 to humidify the wet area space 10.

[0108] Among them, the wet space 10 may include a weight detection device, which can detect the weight of the items placed in the wet space 10 and transmit the detected weight to the control device. In this embodiment, after a new item is placed in the wet space 10, the items placed in the wet space 10 can be weighed once, and the detected weight is recorded as the initial weight M0. In addition, the weight detection device can weigh once every set time interval (for example, 12 hours), and the detected weight is recorded as the current weight Mi. The value of (M0-Mi) / M0 is recorded as the weight loss ratio. If the weight loss ratio is greater than the set loss threshold (which can be set according to actual needs, such as 2%), it can be determined that the wet space 10 has a humidification demand.

[0109] In addition, in this embodiment, the humidity control space 20 may include an air inlet channel connected to the humidity control module 21, and the air inlet channel includes a fourth control valve 261, and the fourth control valve 261 is used to control the opening or closing of the air inlet channel. When the objects such as fruits and vegetables that need to be placed in the wet space 10 are just placed in the wet space 10, there may be a situation where the cooling rate becomes faster and the weight loss of the placed objects increases. Therefore, a certain humidity can be prepared for the wet space 10 at the initial stage of placing the placed objects. In this case, the fourth control valve 261 and the second control valve 231 can be opened, and the first control valve 221 and the third control valve 241 can be closed, that is, the air inlet channel and the exhaust channel are connected, the dehumidification channel and the humidification channel are closed, and the gas outside the humidity control device enters the humidity control space 20 through the air inlet channel, and the water absorbing material in the humidity control space 20 absorbs the moisture entering the gas and discharges it to the outside of the humidity control space through the exhaust channel.

[0110] Among them, the exhaust channel may include a second humidity detection device 232, and the second humidity detection device 232 is located between the second control valve 231 and the humidity control module 21. The second humidity detection device 232 can detect the humidity of the gas in the exhaust channel. When the fourth control valve 261 and the second control valve 231 are in an open state, and the first control valve 221 and the third control valve 241 are in a closed state, the humidity value detected by the second humidity detection device 232 can be transmitted to the control device. When the control device determines that the humidity value is greater than the second humidity threshold, it means that the water-absorbing material has absorbed enough moisture, and the fourth control valve 261 and the third control valve 241 can be closed. When the wet zone space 10 has a humidification demand, the third control valve 241, the second far-infrared drying device 25 and the second fan 242 can be opened to humidify the wet zone space 10.

[0111] It should be noted that the second humidity threshold may be smaller than the first humidity threshold, and the size of the second humidity threshold may be set according to actual needs and is not limited thereto.

[0112] In addition, in this embodiment, after the humidification space is humidified using the humidity regulating space 20, it can be determined whether the dry space 30 has a drying demand. When it is determined that the dry space 30 has no drying demand and the wet space 10 has no new humidification demand, the fourth control valve 261 and the second control valve 231 can be opened, and the first control valve 221 and the third control valve 241 can be closed. External gas is used to provide moisture for the humidity regulating space 20 until the humidity value detected by the second humidity detection device 232 is greater than the second humidity threshold value. The fourth control valve 261 and the second control valve 231 are then closed to prepare new moisture for the subsequent humidification demand of the humidified space.

[0113] In this embodiment, the humidity-controlled space 20 can absorb moisture not only from the dry space 30, but also from the outside of the humidity-controlled device, so as to better prepare sufficient moisture for the wet space 10. When the wet space 10 has a humidification demand, the moisture absorbed by the humidity-controlled space 20 can be released to the wet space 10, so as to realize the humidification of the wet space 10.

[0114] In an exemplary embodiment, a humidity adjustment device and a humidity adjustment method are provided. Figures 1 to 9 As shown, the humidity control space 20 may include a buffer subspace 201 and a humidity control subspace 202, and the water absorbing material may be disposed in the humidity control subspace 202. The buffer subspace 201 is located between the humidity control subspace 202 and the wet zone space 10, and the humidification channel includes a moisture permeable hole, which is located in the buffer subspace 201.

[0115] When the wet space 10 has a humidification demand, the water-absorbing material of the humidity-adjusting subspace 202 can release water and transfer it to the wet space 10. In this process, the second far-infrared drying device 25 is required to heat the water-absorbing material. The temperature of the humidity-adjusting subspace 202 is generally higher than the temperature of the wet space 10. Therefore, as the gas is transferred to the wet space 10, the gas may condense into water droplets in the humidification channel, that is, condensation may be generated in the humidification channel. The condensation can be discharged to the outside of the humidification channel through the moisture permeable holes and drip to the bottom of the buffer subspace 201, thereby preventing the condensation from entering the wet space 10.

[0116] The humidification channel may include a third air suction fan, and the third air suction fan may be located at a connecting position between the buffer subspace 201 and the humidity control subspace 202, that is, Figure 6The third suction fan is used to move the gas in the humidification channel from the humidity control subspace 202 to the buffer subspace 201 to better humidify the wet zone space 10.

[0117] The bottom surface of the humidity-conditioning space 20 is inclined downward from the buffer subspace 201 to the humidity-conditioning subspace 202, that is, in the vertical direction, the bottom surface of the buffer subspace 201 is higher than the bottom surface of the humidity-conditioning subspace 202. In addition, the buffer subspace 201 and the humidity-conditioning subspace 202 are separated by a partition 203, and a gate 204 is provided between the partition 203 and the bottom surface. A gravity sensing device is provided in the area where the bottom surface is located in the buffer subspace 201. When the gravity sensing device detects a weight change on the bottom surface, it indicates that condensation exists in the buffer subspace 201, and the gate 204 can be controlled to be in an open state (refer to Fig. 9 As shown in FIG. 2 ), the condensation in the buffer subspace 201 flows into the humidity control subspace 202. The bottom surface of the buffer subspace 201 is higher than the bottom surface of the humidity control subspace 202, which makes it easier for the condensation to flow from the buffer subspace 201 into the humidity control subspace 202. When the gravity sensing device detects that there is no weight change on the bottom surface, it means that there is no condensation in the buffer subspace 201, and the gate 204 can be controlled to be in a closed state (refer to FIG. 2 ). Figure 8 as shown).

[0118] In addition, in this embodiment, when the wet space 10 has a humidification demand, not only the second far-infrared drying device 25, the third control valve 241 and the second fan 242 can be turned on, but also the third suction fan can be turned on synchronously, so as to better transmit the high-humidity gas in the humidity control subspace 202 to the wet space 10. In addition, when the second far-infrared drying device 25 is in the turned-on state, if there is condensation in the humidity control subspace 202, it can not only heat the water-absorbing material, but also heat the condensation, so as to heat the condensation into gas, and transmit it to the wet space 10 through the humidification channel together, so as to achieve reuse.

[0119] The humidity regulating subspace 202 in this embodiment can store water in various forms. It can absorb moisture discharged from the dry space 30 for water storage, or it can absorb moisture in the air outside the humidity regulating device for water storage. It can also collect condensation formed in the buffer subspace 201, and heat and release it when needed to achieve the purpose of humidifying the wet space 10, and can make better and more rational use of resources.

[0120] In an exemplary embodiment, a refrigerator is provided. The refrigerator includes the humidity regulating device in the above embodiment, thereby having the same effect as the above humidity regulating device. Figures 1 to 9As shown, in the refrigerator, the humidity control module 21 can release the moisture absorbed from the dry space 30 to the wet space 10, realize the linkage between the dry space 30 and the wet space 10, maximize the resource utilization, and save energy. Moreover, since the refrigerator can actively humidify the wet space 10, compared with the solution of the gas regulating membrane in the related art, the refrigerator can achieve a better preservation effect even when there are fewer items placed in the wet space 10, and better avoid the phenomenon of wilting and water loss of the items placed in the wet space 10.

[0121] In some embodiments,

[0122] refer to Figures 1 to 9 As shown, the humidity regulating device of the refrigerator may include a detection device, a calculation device, a timing device, a control device, a regulating device and a judgment device, wherein the regulating device includes a first drying device 31 and a humidity regulating space 20, the first drying device 31 may include a plurality of first far-infrared drying devices, the humidity regulating space 20 includes a second far-infrared drying device 25, and the detection device includes a weight detection device, a distance detection device 32, a temperature detection device, a humidity detection device, etc., wherein the distance detection device 32 detects the distance between the placed items placed in the dry space 30 and the drying device. The calculation device can calculate the volume occupied by the placed items placed in the dry space 30 according to the information detected by the distance detection device 32. The timing device can record the opening time of the drying device. Each device is connected to the control device, and the control device performs corresponding control according to the information fed back by the other devices.

[0123] This embodiment may include two racks, which are respectively installed in the wet space 10 and the dry space 30, and the items are placed on the above racks. The rack of the wet space 10 can be recorded as a first rack 51, and the rack of the dry space 30 can be recorded as a second rack 52. The first rack 51 and the second rack 52 can have evenly distributed small holes. For example, the items (such as fruits and vegetables) placed in the wet space 10 are placed on the first rack 51. The small holes on the first rack 51 can facilitate the pre-cooling of fruits and vegetables, and can also prevent the accumulation of moisture from causing the fruits and vegetables to spoil. The items (such as dry goods) placed in the dry space 30 can be placed on the second rack 52. The small holes on the second rack 52 facilitate the uniform drying of the dry goods. In addition, the first rack 51 and the second rack 52 can be arbitrarily extracted, which is convenient for users to clean.

[0124] It should be noted that the small holes on the first rack 51 and the second rack 52 may be different or the same, and this is not limited. When there is a difference between the two, the first rack 51 generally has a larger volume of fruits and vegetables, so the hole diameter may be larger than the hole diameter of the second rack 52. For example, the diameter of the small hole on the first rack 51 can be set to 15 mm, and the diameter of the small hole on the second rack 52 can be set to 7 mm.

[0125] In this embodiment, the first drying device 31 may include a plurality of first far-infrared drying devices evenly distributed along the top surface of the dry space 30, and the first far-infrared drying devices extend from the entrance of the dry space 30 toward a direction away from the entrance. Through the above arrangement, the items placed in the dry space 30 can be evenly heated and dried.

[0126] The first drying device 31 may include a plurality of distance detection devices 32, and the plurality of distance detection devices 32 correspond to the plurality of first far-infrared drying devices one by one. In the mutually corresponding distance detection devices 32 and the first far-infrared drying devices, the distance detection device 32 is located in the middle of the extension direction of the first far-infrared drying device. The distance detection device 32 is used to detect the distance between the placed items placed in the drying space 30 and the first far-infrared drying device. The distance parameter obtained by each distance detection device 32 can control the number of first far-infrared drying devices to be opened, thereby avoiding excessive waste of resources.

[0127] The humidity control space 20 may include a buffer subspace 201 and a humidity control subspace 202. The humidity control subspace 202 is provided with a humidity control module 21. The humidity control module 21 may include a water-absorbing material capable of absorbing water. The water-absorbing material may be, for example, a high molecular polymer with a relatively large molecular weight, high hydrophilicity, and good water storage performance, such as N-isopropylacrylamide. When its temperature is lower than the critical temperature, the molecule is helical and has hydrophilicity, that is, it has good hygroscopic performance; when its temperature exceeds the critical temperature, it changes from hydrophilicity to hydrophobicity, and may be accompanied by structural contraction, and the molecular form becomes a small spherical shape, and the adsorbed water molecules can be released by squeezing to achieve the effect of "automatic water release".

[0128] The bottom surface of the humidity-conditioning space 20 is inclined downward from the buffer subspace 201 to the humidity-conditioning subspace 202, that is, in the vertical direction, the bottom surface of the buffer subspace 201 is higher than the bottom surface of the humidity-conditioning subspace 202. In addition, the buffer subspace 201 and the humidity-conditioning subspace 202 are separated by a partition 203, and a gate 204 is provided between the partition 203 and the bottom surface. A gravity sensing device is provided in the area of ​​the bottom surface located in the buffer subspace 201. When the gravity sensing device detects a weight change on the bottom surface, it indicates that condensation exists in the buffer subspace 201, and the gate 204 can be controlled to be in an open state (refer to Fig. 9 As shown in FIG. 2 ), the condensation in the buffer subspace 201 flows into the humidity control subspace 202. The bottom surface of the buffer subspace 201 is higher than the bottom surface of the humidity control subspace 202, which makes it easier for the condensation to flow from the buffer subspace 201 into the humidity control subspace 202. When the gravity sensing device detects that there is no weight change on the bottom surface, it means that there is no condensation in the buffer subspace 201, and the gate 204 can be controlled to be in a closed state (refer to FIG. 2 ). Figure 8 as shown).

[0129] The humidity control module 21 can absorb moisture from the humid air in the dehumidification channel and the air inlet channel at a relatively low temperature. When the wet area space 10 needs to be humidified, the humidification hole 245 can be controlled to open, and the second far-infrared device can be turned on to heat the water absorbing material of the humidity control module 21, so that the absorbed moisture is released into the wet area space 10.

[0130] Among them, if at least one distance value among the distance values ​​detected by the multiple distance detection devices 32 is less than the distance between the distance detection device 32 and the bottom of the dry space 30, it means that there are items placed in the dry space 30. After the items such as dry goods that need to be placed in the dry space 30 are placed in the dry space 30, if the first humidity detection device 223 detects that the humidity value is greater than the first humidity threshold, it means that the dry space 30 of the refrigerator has a drying demand, and the food placed therein can be detected by the distance detection device 32. If the distance value detected is equal to the distance H0 between the distance detection device 32 and the bottom of the dry space 30 (i.e., the second shelf 52), there is no food placed in the area where it is located, so the second far-infrared drying device 25 at this position can be turned off. At the same time, the second shelf 52 in each dry space 30 has a fixed length L0 and width W0, and the total available volume V0 in the dry space 30 can be calculated based on H0, L0 and W0. After putting the food in, assuming that the depth distance of the food is equal to W0, the occupied volume V of the food can be approximately calculated based on the evenly distributed first far-infrared drying devices and the actual maximum value Hmax of the food height size. If the ratio of the occupied volume V to the available total volume V0 is R∈(0,25%), the first far-infrared drying device is turned on for t1; if the ratio is R∈[25,50%), the first far-infrared drying device is turned on for t2; if the ratio is R∈[50,75%), the first far-infrared drying device is turned on for t3.

[0131] In addition, when the refrigerator has a drying requirement, the fourth control valve 261 and the third control valve 241 can be closed, and the first control valve 221 and the second control valve 231 can be opened, and the dehumidification hole and the first fan 222 can be opened at the same time, and the humid air heated and discharged in the dry area 30 can be discharged from the exhaust channel after moisture adsorption by the humidity control module 21. The moisture adsorbed by the humidity control module 21 can be used when there is a humidification requirement.

[0132] When fruits and vegetables and other items that need to be placed in the wet space 10 are just placed in the wet space 10, there may be a situation where the cooling rate becomes faster and the weight loss of fruits and vegetables increases. Therefore, a certain humidity can be provided to the wet space 10 at the initial stage of placing fruits and vegetables. Before placing fruits and vegetables or when there is no regulation demand in the wet space 10, the inlet of the air inlet pipe 262 of the air inlet channel in the refrigerator can be opened, and the first control valve 221 and the third control valve 241 are closed, the fourth control valve 261 and the second control valve 231 are opened, and the humidity control module 21 adsorbs the moisture in the gas entering from the air inlet pipe 262, and the gas after the moisture is adsorbed is discharged to the outside of the refrigerator through the exhaust channel. In this process, if the humidity value detected by the second humidity detection device 232 is greater than the first humidity threshold, it means that the humidity control module 21 has adsorbed enough moisture, and the second control valve 231 and the fourth control valve 261 can be closed.

[0133] In this embodiment, when the humidity value detected by the second humidity detection device 232 in the refrigerator is less than the second humidity threshold value, it means that the wet zone space 10 has a humidification demand, and the first control valve 221, the second control valve 231, the fourth control valve 261 and the first fan 222 can be closed, and the third control valve 241, the second fan 242, the third suction fan and the humidification hole 245 can be opened, and the second far-infrared drying device 25 is turned on to irradiate the water-absorbing material of the humidity control module 21, so that it is heated to release the adsorbed moisture, and the wet zone space 10 is humidified.

[0134] In addition, in this embodiment, the fruits and vegetables placed in the wet area space 10 can also be weighed and recorded as M0. And then weighed every 12 hours and recorded as Mi. If the value of (M0-Mi) / M0 (i.e., the weight loss ratio) is greater than 2%, it means that the humidity difference in the wet area space 10 is large, which means that the wet area space 10 has a humidification demand. When the wet area space 10 has a humidification demand, the second humidity detection device in the refrigerator detects that the humidity value is less than the first humidity threshold. At this time, the first control valve 221, the second control valve 231, the fourth control valve 261 and the first fan 222 can be closed, and the third control valve 241, the second fan 242, the third suction fan and the humidification hole 245 are opened, and the second far-infrared drying device 25 is opened to irradiate the water-absorbing material of the humidity control module 21, so that it is heated to release the adsorbed moisture, and the wet area space 10 is humidified.

[0135] It should be noted that when the second far-infrared drying device 25 is turned on, it can not only make the water absorbing material release water, but also make the condensation in the humidity control subspace 202 evaporate into gas and enter the wet zone space 10 through the humidification channel for humidification.

[0136] In this embodiment, the dry space 30 may also be provided with a weight detection device. When the weight detected by the weight detection device is zero or the humidity value detected by the second humidity detection device 232 is less than the second humidity threshold, it indicates that the dry space 30 has no drying requirement. If the dry space 30 is not dried at this time, no action is required. If the dry space 30 is being dried at this time, the first far-infrared drying device in the dry space can be closed, and the dehumidification hole, the first control valve 221 and the first fan 222 can be closed. At the same time, if it is necessary to replenish moisture to the humidity control module 21, the third control valve 241 and the second control valve 231 can be opened at the same time, and the humidity control module 21 absorbs moisture in the gas entering from the air inlet channel, and the gas after the moisture is absorbed is discharged to the outside of the refrigerator through the exhaust channel. Until the humidity value detected by the second humidity detection device 232 is greater than the first humidity threshold, it means that the humidity control module 21 has absorbed enough moisture, and the second control valve 231 and the fourth control valve 261 can be closed. When there is a humidification requirement in the wet space 10, moisture is released.

[0137] Among them, t3>t2>t1, the values ​​of L0, H0 and W0 are determined according to the size of the actual built-in shelf of the refrigerator, and the first humidity threshold and the second humidity threshold can be set according to actual needs. For example, the first humidity threshold can be 90% and the second humidity threshold can be 30%.

[0138] Compared with the related art, this embodiment adds a humidity control space 20, and connects the humidity control space 20 with the dry space 30 and the wet space 10, respectively, so as to realize the linkage between the wet space 10 and the dry space 30. In addition, a first drying device 31 is provided in the dry space 30, which is used to diffuse the moisture of the items placed in the dry space 30 to the dry space 30. In addition, the humidity control module 21 is provided in the humidity control space 20 of this embodiment. When the dry space 30 has a drying requirement, the first drying device 31 diffuses the moisture of the items placed in the dry space 30 to the dry space 30, and then the humidity control module 21 can absorb the moisture in the dry space 30, so as to realize the drying of the dry space 30 and better preserve the items placed in the dry space 30. When the wet space 10 has a drying requirement, the humidity control module 21 can release moisture to the wet space 10, so as to increase the humidity of the wet space 10.

[0139] That is to say, the humidity control module 21 can release the moisture absorbed from the dry space 30 to the wet space 10, realize the linkage between the dry space 30 and the wet space 10, realize the maximum resource utilization, and save energy consumption. Moreover, since this embodiment can actively humidify the wet space 10 through the humidity control module 21, compared with the solution of the gas regulating membrane in the related art, even when there are fewer items placed in the wet space 10, the solution of this embodiment can also achieve a better preservation effect, and better avoid the phenomenon of wilting and water loss of the items placed in the wet space 10.
