[0016] In some embodiments of the present application, a connection end between the connecting tube and the water storage chamber is spaced from a bottom wall of the water storage chamber.

[0017] In some embodiments of the present application, the connecting end of the connecting tube and the water storage chamber is arranged higher than the bottom wall of the water storage chamber, so that there is still water storage space below the connecting end of the connecting tube and the water storage chamber, which is convenient for storing condensed water entering the water collection chamber.

[0018] In some embodiments of the present application, the dehumidification device includes an air duct shell, a semiconductor refrigeration structure and a water collecting box, the air duct shell is constructed to form an air flow channel, the cold end and the hot end of the semiconductor refrigeration structure are respectively in contact with the air duct shell, and in the air flow direction of the air flow channel, the contact position between the cold end of the semiconductor refrigeration structure and the air duct shell is located downstream of the contact position between the hot end of the semiconductor refrigeration structure and the air duct shell; a first fan is arranged in the air flow channel; the water collecting box forms a water collecting chamber connected to the air flow channel.

[0050] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0051] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and common meanings.

[0052] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0053] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0054] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0055] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0056] In the related art, refrigerators are usually equipped with two independent spaces, a dry area and a wet area. The dry area is used to store items with low humidity requirements, such as dry goods; the wet area is used to store items with high humidity requirements, such as vegetables and fruits. The dry area and the wet area are set up independently and unrelated, and the storage environment is single, which affects the low space utilization rate.

[0057] When the user only uses the wet area to store fruits and vegetables, the storage space in the dry area is wasted, and sometimes there is even a shortage of space in the wet area; when the user only uses the dry area to store dry goods, the storage space in the wet area is wasted, and sometimes there is a shortage of space in the dry area.

[0058] In some refrigerator products, a humidifier and a dryer are arranged in the same storage space, so that the storage space can be converted between a wet storage space and a dry storage space. However, users cannot use the dry storage and the wet storage at the same time, and the installation of the humidifier and the dryer takes up a lot of space, affecting the storage space.

[0059] In view of this, the embodiment of the present application respectively sets a humidifying device and a dehumidifying device in the two chambers, so that the two chambers can form a dry storage environment and a wet storage environment respectively; and a damper is set between the two chambers to separate the two chambers, so that the two chambers form different storage environments; the damper is also configured to connect the two chambers, so that the two chambers form the same storage environment, and expand the storage space of the same storage environment. This can not only improve the diversity and flexibility of the storage environment, but also facilitate users to set the storage environment of the two chambers according to actual conditions, thereby improving the utilization rate of the storage space.

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0061] First of all, it should be noted that in the embodiment of the present application, the width direction of the door body corresponds to the X-axis direction in the accompanying drawings; the thickness direction of the door body corresponds to the Y-axis direction in the accompanying drawings; the height direction of the door body, that is, the up-down direction, corresponds to the Z-axis direction in the accompanying drawings. In addition, in the description of the embodiment of the present application, the directional word "rear" refers to the side close to the door body, and the directional word "front" refers to the side away from the door body.

[0062] like Figure 1 As shown, the refrigerator of the embodiment of the present application includes a box body 100, and the box body 100 is structured to form a storage compartment 101 with a front opening for storing food and other items. One or more storage compartments 101 can be provided. The storage compartments 101 can be divided into a freezing compartment, a refrigerating compartment, and a temperature-changing compartment according to different storage temperatures.

[0063] Among them, shelves 110 can be set in the refrigerator to increase the placement of items; drawers 120 can be set in the refrigerator to store food in a relatively closed manner; they can be pulled out in the depth direction of the refrigerator to facilitate the classification, storage and retrieval of items.

[0064] The refrigerator of the embodiment of the present application includes a door body 200, which is connected to the box body 100 to open or close the storage compartment. When there are multiple storage compartments 101, there can be one door body 200, and multiple storage compartments 101 share one door body 200; or, there can be multiple door bodies 200, and they are arranged corresponding to different storage compartments 101. In some embodiments of the present application, two door bodies 200 are arranged corresponding to the refrigerating compartment, and one door body 200 is arranged corresponding to the freezing compartment.

[0065] In some embodiments, the door body 200 is rotatably mounted on the box body 100 via a hinge assembly, and the door body 200 rotates relative to the box body 100 to open or close the storage compartment 101 .

[0066] In other embodiments, a drawer 120 is installed in the storage compartment 101. The drawer 120 is installed in the box body 100 through a sliding structure, and the outer end structure of the drawer 120 forms a door body.

[0067] To increase storage space, combine Figure 1 Some refrigeration compartments are usually provided with shelves 210 on the door bodies 200 corresponding to the refrigeration compartments, and the opening of the shelves 210 is upward for storing articles. Usually, a plurality of shelves 210 are provided, and the plurality of shelves 210 are arranged at intervals along the height direction of the door body 200.

[0068] Reference Figures 2 to 4 In some embodiments, the refrigerator further includes a storage shell 300, and the storage shell 300 is installed in the storage compartment 101, and the installation method includes but is not limited to snap-on, bonding, etc.

[0069] The storage housing 300 is structured to form a storage space 310 for storing articles. The front side of the storage space 310 is open to facilitate the taking and placing of articles.

[0070] In some embodiments, items can be placed directly in the storage space 310, which has a larger space.

[0071] In other embodiments, a drawer 120 is provided in the storage space 310, and items are placed in the drawer 120, which facilitates the taking and placing of items; and the stored items can also be separated from the functional components in the storage space 310 to improve safety.

[0072] In some embodiments, the storage shell 300 is constructed to form two chambers, one of which is equipped with a humidifier 500, and the other is equipped with a dehumidifier 400, so as to form different storage environments, such as a high-humidity storage environment and a relatively dry storage environment, thereby improving the diversity of the storage environment of the storage space.

[0073] In some embodiments, the storage housing 300 is configured to form a first chamber 311 and a second chamber 312 .

[0074] In some embodiments, a partition plate 320 is disposed in the storage space 310 to divide the storage space 310 into a first chamber 311 and a second chamber 312 . The structure is simple and the subsequent installation of the damper 330 is facilitated.

[0075] In some possible implementations, the first chamber 311 and the second chamber 312 are arranged side by side along the length direction of the box body (corresponding to the X-axis direction in the drawings). Such an arrangement can include that the depth and height of the first chamber 311 and the second chamber 312 are not affected by the partition plate 320, thereby reducing the impact of the partition plate 320 on the storage space.

[0076] Of course, in some embodiments, the first chamber 311 and the second chamber 312 can be arranged side by side along the height direction of the box (corresponding to the Z-axis direction in the figure). In this way, the height of the first chamber 311 and the second chamber 312 is smaller, which is suitable for placing flatter objects.

[0077] In some embodiments of the present application, Figure 3 As shown, the partition plate 320 is arranged perpendicular to the bottom wall of the storage space 310, so that the first chamber 311 and the second chamber 312 are arranged side by side along the length direction of the box body, and the shapes of the first chamber 311 and the second chamber 312 are regular, which is convenient for the placement of items; and it is convenient to arrange the drawer 120 in the first chamber 311 and the second chamber 312 to improve the convenience of taking and placing items.

[0078] Of course, this is not a limitation on the arrangement angle of the partition plate 320 , and the partition plate 320 may also be inclined toward the first chamber 311 or the second chamber 312 .

[0079] In some embodiments, in combination Figure 1 and Figure 2 The refrigerator further includes two drawers 120, which are respectively installed in the first chamber 311 and the second chamber 312. The two drawers 120 can be pulled out along the depth direction of the refrigerator (corresponding to the Y-axis direction in the figure) to facilitate the taking and placing of items.

[0080] Reference Figure 3 and Figure 4 In some embodiments, an air inlet 301 is provided on the rear side wall of the storage housing 300 to discharge cold air into the storage space 310 to reduce the temperature of the storage space 310 .

[0081] Among them, the air inlet 301 is located at the top of the rear side wall, which is convenient for cold air to flow downward into the drawer 120, which is beneficial to increasing the cooling rate of the storage space 310.

[0082] In some embodiments, two air inlets 301 are provided, which are connected to the first chamber 311 and the second chamber 312 respectively, so as to provide cold air to the first chamber 311 and the second chamber 312 respectively.

[0083] Combination Figure 2 and Figure 3 In some embodiments, a humidifying device 500 is installed in the first chamber 311 to increase the humidity of the first chamber 311 so that the storage environment of the first chamber 311 is conducive to the preservation of food such as fruits and vegetables.

[0084] The humidifying device 500 may be an ultrasonic humidifying device with high humidification efficiency and low noise.

[0085] The humidifying device 500 may also be a pressure atomizing device for humidification, such as a spray nozzle, a centrifugal atomizing device, and the like.

[0086] The humidifying device 500 may also be a humidifying fiber, which cooperates with a blower to blow high-humidity air into the first chamber 311 .

[0087] In some embodiments, a dehumidification device 400 is installed in the second chamber 312 to reduce the humidity of the second chamber 312 so that the storage environment of the second chamber 312 is conducive to the storage of dry goods and other food materials.

[0088] The dehumidification device 400 may be a condensation dehumidification device, an adsorption dehumidification device, or the like.

[0089] In some embodiments of the present application, the refrigerator further includes a damper 330 , and the damper 330 is configured to separate the first chamber 311 and the second chamber 312 , or to connect the first chamber 311 and the second chamber 312 .

[0090] When the damper 330 separates the first chamber 311 and the second chamber 312, the first chamber 311 uses the humidifier 500 to increase the humidity, and the second chamber 312 uses the dehumidifier 400 to reduce the humidity, so that the first chamber 311 and the second chamber 312 form different storage environments suitable for the storage of different types of items.

[0091] When the damper 330 connects the first chamber 311 and the second chamber 312, the humidifying device 500 can be used to simultaneously increase the humidity of the first chamber 311 and the second chamber 312, or the dehumidifying device 400 can be used to simultaneously reduce the humidity of the first chamber 311 and the second chamber 312, so that the first chamber 311 and the second chamber 312 have the same storage environment, thereby expanding the storage space.

[0092] In some embodiments of the present application, a damper 330 is installed on the partition plate 320, which occupies a small installation space and has a compact structure.

[0093] In some embodiments of the present application, the damper 330 is an electric damper, and the opening and closing of the damper 330 is controlled by a control device of the refrigerator without manual operation.

[0094] In some embodiments, the damper 330 is located on the top of the partition plate 320, which reduces the possibility of the damper 330 being blocked by foreign objects when it is opened, and can also avoid interference between the drawer's pull-out structure and the damper 330.

[0095] In some embodiments, the damper 330 is located at the rear of the partition plate 320. This arrangement can hide the damper 330, reduce the possibility of being seen by the user, and benefit the appearance of the refrigerator; and facilitate the cable arrangement of the damper 330.

[0096] When the damper 330 is configured to be opened, the first chamber 311 and the second chamber 312 are communicated, the humidifying device 500 is configured to be activated or the dehumidifying device 400 is configured to be activated, so that the first chamber 311 and the second chamber 312 have a high humidity storage environment or a low humidity dry storage environment.

[0097] When the damper 330 is configured to be closed, the first chamber 311 and the second chamber 312 are partitioned, and the first chamber 311 and the second chamber 312 form different storage environments.

[0098] It should be noted that the humidity of a high-humidity storage environment is greater than that of a low-humidity dry storage environment. For example, when the humidifying device 500 is started, the humidity of the space can reach 75% to 95% and 70% to 90%; when the dehumidifying device 400 is started, the humidity of the space can be reduced to 40% to 50%. The embodiment of the present application does not limit the humidity range of high humidity and low humidity, and the user can set it according to storage requirements.

[0099] In other embodiments of the present application, the refrigerator further comprises a connecting pipe, which may be located outside the storage housing 300, for example, the connecting pipe is located at the rear side or the top side of the storage housing 300; the connecting pipe connects the first chamber 311 and the second chamber 312. A damper 330 may be provided in the connecting pipe to achieve the connection or isolation of the first chamber 311 and the second chamber 312. In this arrangement, the damper 330 is located outside the storage housing 300, so as to avoid the damper 330 from affecting the drawer pulling operation in the storage housing 300.

[0100] Continue to refer to Figure 2 and Figure 3In some possible implementations, the humidifying device 500 is installed on the rear wall of the storage shell 300. With this arrangement, the humidifying device 500 can be hidden at the rear side of the drawer, reducing the possibility of being seen by the user; moreover, it is convenient to arrange the cables of the humidifying device 500 to achieve electrical connection with the refrigerator control device, without the need to additionally set up a detachable electrical connection structure.

[0101] In some embodiments, the dehumidification device 400 is installed on the rear side wall of the storage shell 300. Such a configuration can not only hide the dehumidification device 400 at the rear side of the drawer, but also facilitate the electrical connection of the dehumidification device 400 and reduce the impact of the dehumidification device 400 on the drawer pulling.

[0102] In some possible implementations, the humidifying device 500 and the dehumidifying device 400 are symmetrically arranged about the partition plate 320. Such an arrangement facilitates the installation and fixing structure on the storage housing 300 and facilitates the routing of cables.

[0103] Through the above-mentioned configuration, some embodiments of the present application divide the storage space 310 into a first chamber 311 and a second chamber 312 by setting a partition plate 320 in the storage shell 300, and a humidifying device 500 is provided in the first chamber 311 to increase the humidity of the space and provide a high-humidity storage environment; and a dehumidifying device 400 is provided in the second chamber 312 to reduce the humidity of the space and provide a dry storage environment. Furthermore, by arranging a damper 330 on the partition plate 320, the first chamber 311 and the second chamber 312 are connected or isolated. Thus, when the damper 330 is opened, the first chamber 311 and the second chamber 312 are connected. At this time, the humidifying device 500 can be used to humidify the first chamber 311 and the second chamber 312 at the same time to provide a high-humidity storage environment. When the dehumidifying device 400 is used, the first chamber 311 and the second chamber 312 can be dehumidified at the same time to provide a dry storage environment, so that the storage space for both dry and high humidity is larger. When the damper 330 is closed, the first chamber 311 and the second chamber 312 are isolated. At this time, the humidifying device 500 can form a high-humidity storage environment in the first chamber 311. When the dehumidifying device 400 is used, a low-humidity dry storage environment can be formed in the second chamber 312. In this way, the storage space 310 of the embodiment of the present application can form a dry and high-humidity storage environment at the same time, or it can separately form a high-humidity storage environment with a larger storage space and a dry storage environment. The diverse storage environments are convenient for users to set the storage environment according to actual conditions, thereby improving the space utilization of the storage space 310.

[0104] It can be known from the above description that the humidifying device 500 needs to blow water toward the space to increase the humidity of the space. Therefore, in some possible embodiments of the present application, the humidifying device 500 has a water injection pipe 540 for injecting water toward the chamber in the humidifying device 500.

[0105] like Figure 3 and Figure 4 As shown, in some embodiments, a water injection port 302 is provided on the storage housing 300 , and the water injection port 302 is connected to the water injection pipe 540 , so that the user can inject water into the chamber in the humidifying device 500 through the water injection port 302 and the water injection pipe 540 .

[0106] In some embodiments, the water filling port 302 is disposed at the top of the storage housing 300 , providing ample space for water filling operations and making the operation simple.

[0107] As can be seen from the above description, the dehumidifier 400 needs to remove moisture in the space to reduce the humidity of the space. To this end, in some embodiments, the accumulated moisture of the dehumidifier 400 is provided to the humidifier 500, and water can be supplied to the humidifier 500 without additionally cleaning the moisture in the dehumidifier 400.

[0108] Combination Figure 3 and Figure 5 In some embodiments, the dehumidification device 400 has a water collecting chamber 431, which is used to collect the dehumidified water of the dehumidification device 400; the humidification device 500 has a water storage chamber 511, which is used to increase the water supply for the humidification device 500. The water storage chamber 511 is connected to the water injection pipe 540, and the water storage chamber 511 is injected with water by using the water injection port 302 and the water injection pipe 540.

[0109] In some embodiments, the water collecting chamber 431 and the water storage chamber 511 are connected via a connecting tube 600 , so that the water in the water collecting chamber 431 can enter the water storage chamber 511 for humidification, which helps reduce the frequency of manual water replenishment of the water storage chamber 511 by the user.

[0110] In some embodiments of the present application, the connecting pipe 600 passes through the partition plate 320. When the humidifying device 500 and the dehumidifying device 400 are both installed on the rear side wall of the storage housing 300, the setting of the connecting pipe 600 has little effect on the storage and the drawer pulling operation.

[0111] There is usually a large amount of water in the water storage chamber 511. In order to prevent the water in the water storage chamber 511 from flowing back into the water collecting chamber 431, a control valve 610 is provided on the connecting pipe 600. The control valve 610 is constructed to allow the water in the water collecting chamber 431 to flow to the water storage chamber 511 in one direction, and the water in the water storage chamber 511 cannot flow back into the water collecting chamber 431.

[0112] Exemplarily, the control valve 610 is a one-way valve, and no additional cables are required for control.

[0113] The control valve 610 may be located in the first chamber 311 , or may be located in the second chamber 312 .

[0114] In some embodiments, along the height direction of the box body, the connection end of the connecting tube 600 and the water collecting chamber 431 is higher than the connection end of the connecting tube 600 and the water storage chamber 511 .

[0115] Exemplarily, the connecting pipe 600 is an inclined pipe, the higher end of the connecting pipe 600 is connected to the water collecting chamber 431 , and the lower end of the connecting pipe 600 is connected to the water storage chamber 511 .

[0116] In this way, the connecting end of the connecting tube 600 and the water collecting chamber 431 is higher, while the connecting end of the connecting tube 600 and the water storage chamber 511 is lower. Under the action of gravity, the water in the water collecting chamber 431 flows into the water storage chamber 511 through the connecting tube 600, reducing the possibility of water staying in the connecting tube 600.

[0117] Usually, since the water injection pipe 540 injects water into the water storage chamber 511, the water level in the water storage chamber 511 is higher than the water level in the water collecting chamber 431, resulting in that the water in the water collecting chamber 431 cannot enter the water storage chamber 511. Therefore, when the water level in the water storage chamber 511 is lower than the water level in the water collecting chamber 431, the water in the water collecting chamber 431 can enter the water storage chamber 511 for water replenishment.

[0118] In some embodiments, there is a gap between the connecting end of the connecting tube 600 and the water storage chamber 511 and the bottom wall of the water storage chamber 511. In this way, there is still a water storage space between the connecting end of the connecting tube 600 and the water storage chamber 511 and the bottom wall of the water storage chamber 511. When the water level in the water storage chamber 511 is lower than the connecting end of the connecting tube 600 and the water storage chamber 511, the water in the water collecting chamber 431 enters the water storage chamber 511.

[0119] In some embodiments, a water flow gathering area is provided on the bottom wall of the water collecting chamber 431. The water flow gathering area is the lowest point of the water collecting chamber 431, which facilitates the water flow to gather here. The connecting pipe 600 is connected to the water flow gathering area of ​​the water collecting chamber 431, which is conducive to draining the water in the water collecting chamber 431.

[0120] Among them, the water flow gathering area can be a recessed area set on the bottom wall of the water collecting chamber 431; or, the bottom wall of the water collecting chamber 431 is an inclined bottom wall, and the connecting pipe 600 is connected to the lowest point of the inclined bottom wall, which is conducive to draining the water in the water collecting chamber 431.

[0121] The specific structures and functions of the dehumidification device 400 and the humidification device 500 are described below in conjunction with the accompanying drawings.

[0122] Combination Figure 6 and Figure 7 In some embodiments, the dehumidification device 400 includes an air duct housing 410 , and the air duct housing 410 is configured to form an air flow channel 411 so that gas flows through the air flow channel 411 .

[0123] like Figure 8 and Fig. 9 As shown, in some embodiments, two ends of the air flow channel 411 are an air inlet port 401 and an air outlet port 402 , respectively.

[0124] The air inlet direction of the air inlet port 401 and the air outlet direction of the air outlet port 402 can be the same, which is conducive to improving the compactness of the structure of the air duct housing 410. For example, in some embodiments of the present application, the air inlet direction of the air inlet port 401 and the air outlet direction of the air outlet port 402 are both upward.

[0125] The air inlet direction of the air inlet port 401 and the air outlet direction of the air outlet port 402 may be different, so as to reduce the possibility that the gas from the air outlet port 402 directly enters the air inlet port 401 again.

[0126] The air inlet port 401 and the air outlet port 402 are spaced apart from each other, so as to reduce the possibility that the gas from the air outlet port 402 directly enters the air inlet port 401 .

[0127] In some embodiments, the dehumidification device 400 further includes a semiconductor refrigeration structure 420, which has a cold end and a hot end. The hot end of the semiconductor refrigeration structure 420 is used to heat the gas, and the cold end of the semiconductor refrigeration structure 420 is used to reduce the gas temperature so that the moisture in the air condenses and precipitates.

[0128] The semiconductor refrigeration structure 420 uses the thermoelectric effect of semiconductor materials to achieve refrigeration. When direct current passes through a thermocouple composed of two different semiconductor materials connected in series, heat can be absorbed (cold end) and heat can be released (hot end) at both ends of the thermocouple, thereby achieving the purpose of refrigeration.

[0129] In some embodiments, the semiconductor refrigeration structure 420 includes a plurality of semiconductor refrigeration sheets, and the plurality of semiconductor refrigeration sheets are spaced apart along a set direction.

[0130] In some embodiments, the cold end and the hot end of the semiconductor refrigeration structure 420 are respectively in contact with the air duct housing 410 to transfer heat to the air flow channel 411. Exemplarily, the cold end and the hot end of the semiconductor refrigeration structure 420 are respectively connected to the air duct housing 410, and the connection method is simple and reliable.

[0131] In some embodiments, the cold end and the hot end of the semiconductor refrigeration structure 420 extend into the air flow channel 411 respectively, so that the air can directly contact the cold end and the hot end of the semiconductor refrigeration structure 420, and the heat transfer effect is better.

[0132] In the embodiment of the present application, in the airflow direction of the airflow channel 411, the contact position between the cold end of the semiconductor refrigeration structure 420 and the air duct shell 410 is located downstream of the contact position between the hot end of the semiconductor refrigeration structure 420 and the air duct shell 410. In this way, after the air enters the airflow channel 411 through the air inlet port 401, it first passes through the hot end of the semiconductor refrigeration structure 420, then passes through the cold end of the semiconductor refrigeration structure 420, and is finally discharged through the air outlet port 402.

[0133] With such arrangement, the temperature of the air rises after passing through the hot end of the semiconductor refrigeration structure 420; when passing through the cold end of the semiconductor refrigeration structure 420, the temperature difference between the two is large, which is conducive to the condensation of moisture in the air and improves the dehumidification efficiency.

[0134] The humid hot air contacts the air flow channel 411 at the cold end to avoid heat and moisture exchange. When the humid air temperature drops to the dew point temperature corresponding to its relative humidity, the gaseous water vapor in the humid air will gradually turn into liquid and precipitate to form small water droplets.

[0135] In some embodiments, the dehumidification device 400 further includes a first fan 440 , which is disposed in the air flow channel 411 to provide power for the air flow through the air flow channel 411 .

[0136] In some embodiments, the first fan 440 is installed at the port of the air flow channel 411, and the installation structure is simple.

[0137] In some embodiments, the first fan 440 is installed at the air inlet port 401 of the air flow channel 411 to form a negative pressure in the air flow channel 411 , and the first fan 440 draws air into the air flow channel 411 .

[0138] In some embodiments, the first fan 440 is installed at the air outlet port 402 of the airflow channel 411 to form a positive pressure in the airflow channel 411 and discharge the air from the airflow channel 411, which is beneficial to maintaining the airflow stability in the airflow channel 411, reducing airflow fluctuations, and reducing noise.

[0139] In some embodiments, the dehumidification device 400 further includes a water collecting box 430 , which forms a water collecting chamber 431 communicating with the air flow channel 411 .

[0140] In some embodiments, the water collection box 430 is located at the bottom of the air duct housing 410 , so that the condensed water in the air flow channel 411 can easily enter the water collection chamber 431 .

[0141] In some embodiments of the present application, the water collecting box 430 and the air flow channel 411 are connected via a connecting pipe 460 . Such a configuration is conducive to adjusting the height relationship between the water collecting box 430 and the water storage chamber 511 .

[0142] The dehumidification device 400 of the embodiment of the present application forms an air flow channel 411 by setting an air duct shell 410 to provide a channel for gas flow; and provides a first fan 440 in the air flow channel 411 to provide power for gas flow; and provides a semiconductor refrigeration structure 420, the cold end and the hot end of the semiconductor refrigeration structure 420 are respectively in contact with the air duct shell 410, and the cold end of the semiconductor refrigeration structure 420 is used to condense and precipitate moisture in the air, thereby reducing the humidity in the air; and a water collection box 430 is provided to form a water collection chamber 431 to temporarily store condensed water. The embodiment of the present application uses the semiconductor refrigeration structure 420 to form condensed water, and the structure is simple and reliable.

[0143] Combination Figure 8 and Fig. 9 In some embodiments, the air flow channel 411 includes a first connecting segment 4111 , and a port of the first connecting segment 4111 forms an air inlet port 401 .

[0144] In some embodiments, the air flow channel 411 includes a second connecting segment 4112 , and a port of the second connecting segment 4112 forms an air outlet port 402 .

[0145] In some embodiments, the second connecting section 4112 and the first connecting section 4111 are opposite to each other along a preset direction and have a gap. For example, the second connecting section 4112 and the first connecting section 4111 are opposite to each other along the width direction of the refrigerator and have a gap. In this way, the semiconductor refrigeration structure 420 can use the straight semiconductor refrigeration sheet in the related art. The structure of the semiconductor refrigeration structure 420 is simple, and there is no need to set up special-shaped semiconductor refrigeration sheets, which is conducive to reducing processing costs.

[0146] In some embodiments, the air duct shell 410 forming the first connection section 4111 is connected to the hot end of the semiconductor refrigeration structure 420 , and the air duct shell 410 forming the second connection section 4112 is connected to the cold end of the semiconductor refrigeration structure 420 .

[0147] In some embodiments, the first connecting section 4111 is a straight pipe section, which facilitates the connection between the hot end of the semiconductor refrigeration structure 420 and the part of the air duct shell 410 that forms the first connecting section 4111 .

[0148] In some embodiments, the second connecting section 4112 is a straight pipe section, which facilitates the connection between the cold end of the semiconductor refrigeration structure 420 and the part of the air duct shell 410 that forms the second connecting section 4112 .

[0149] In some embodiments, the second connecting segment 4112 is connected to the first connecting segment 4111. For example, the second connecting segment 4112 is directly connected to the first connecting segment 4111.

[0150] For another example, in some embodiments, the gas flow channel 411 further includes a middle section 4113, and the second connection section 4112 and the first connection section 4111 are connected through the middle section 4113. In this way, the first connection section 4111 and the second connection section 4112 have the same interval along their extension direction, which facilitates the installation of the semiconductor refrigeration structure 420. Moreover, by providing the middle section 4113, a buffer path is provided between the heating part and the condensation part of the gas flow channel 411, so as to avoid the distance between the two being too close to affect the condensation effect.

[0151] In some embodiments, the middle section 4113 may be an arc-shaped pipe section, for example, a semicircular pipe section, so that the air duct shell 410 forms a U-shaped structure, thereby improving the aesthetics of the dehumidification device 400.

[0152] In addition, the middle section 4113 is located below the second connecting section 4112, and the middle section 4113 is connected to the water collecting box 430, so as to facilitate the condensed water to gather downward.

[0153] When the middle section 4113 is an arc-shaped pipe section, the lowest point of the middle section 4113 is connected to the water collecting box 430, so as to drain the condensed water in the air duct shell 410 into the water collecting box 430.

[0154] In the embodiment of the present application, the air flow channel 411 is divided into three parts, and the first connecting section 4111 and the second connecting section 4112 are opposite to each other in a preset direction and have a gap therebetween, so that the hot end of the semiconductor refrigeration structure 420 is connected to the first connecting section 4111, and the cold end of the semiconductor refrigeration structure 420 is connected to the second connecting section 4112; by setting the middle section 4113 between the first connecting section 4111 and the second connecting section 4112, the first connecting section 4111 and the second connecting section 4112 can have the same gap along their extension direction, which is convenient for the installation of the semiconductor refrigeration structure 420; and a buffer path can be provided between the heating point and the condensation point of the gas in the air flow channel 411 to avoid the condensation effect being affected by the close distance between the two.

[0155] In some embodiments, condensing fins 450 are provided in the air flow channel 411. The condensing fins 450 are located in the second connecting section 4112, which is beneficial to increase the heat exchange area between the gas and the cooling end of the semiconductor refrigeration structure 420, thereby improving the condensation efficiency.

[0156] In some embodiments, a plurality of condensing fins 450 are provided, and the plurality of condensing fins 450 are arranged at intervals along the extension direction of the second connecting section 4112, so as to further increase the heat exchange area.

[0157] In some embodiments, the condensing fins 450 are inclined toward the middle section 4113, so that the condensing fins 450 are inclined downward. Such a configuration not only facilitates the condensed water to drip downward along the condensing fins 450, but also helps to increase the flow resistance of the airflow in the second connecting section 4112, thereby increasing the residence time of the airflow in the second connecting section 4112, and thus improving the heat exchange efficiency.

[0158] In some embodiments, the angle between the condensing fins 450 and the horizontal plane is greater than 45°, which is beneficial to increase the flow resistance of the air and facilitate the water droplets to drip downward.

[0159] In some embodiments, the angle between the condensing fins 450 and the horizontal plane is less than 70°, or 75°, so that the condensing fins 450 are close to a vertical state, further promoting the condensed water droplets to drip downward; avoiding the angle between the condensing fins 450 and the horizontal plane being too large, reducing the flow resistance of the air, and thereby reducing the residence time of the air in the second connecting section 4112.

[0160] In some embodiments, a heat exchange layer is provided on the condensing fin 450, and the heat exchange layer may be heat dissipating silicone grease, etc., to improve the heat exchange efficiency.

[0161] In some embodiments, the air duct shell 410 includes two second parts 413, which are respectively connected to the cold end and the hot end of the semiconductor refrigeration structure 420. One of the second parts 413 is located on the side of the first connecting section 4111 facing the second connecting section 4112, and is connected to the hot end of the semiconductor refrigeration structure 420; the other second part 413 is located on the side of the second connecting section 4112 facing the first connecting section 4111, and is connected to the cold end of the semiconductor refrigeration structure 420.

[0162] In some embodiments, the air duct housing 410 further includes a first portion 412 , and the rest of the air duct housing 410 except the second portion 413 is the first portion 412 .

[0163] In some embodiments, the heat transfer coefficients of the two second parts 413 are greater than the heat transfer coefficient of the first part 412 . For example, the second parts 413 may be made of metal, and the first part 412 may be made of plastic.

[0164] Such an arrangement can transfer the heat at the hot end and the cold end of the semiconductor refrigeration structure 420 to the inside of the air flow channel 411 through the second part 413, with high heat transfer efficiency; and the heat transfer coefficient of the first part 412 of the air duct shell 410 is small, reducing the heat exchange between the gas in the air flow channel 411 and the storage space through the first part 412.

[0165] Combination Fig.10In some embodiments, the humidifying device 500 includes a humidifying housing 510 , and the humidifying housing 510 forms a water storage chamber 511 .

[0166] In some embodiments, a plurality of air outlet holes 501 are disposed on the front side of the humidifying housing 510 , so that high-humidity air can enter the storage space through the air outlet holes 501 .

[0167] The multiple air outlet holes 501 can be arranged in many ways, for example, the multiple air outlet holes 501 are arranged in a rectangular matrix, a circular matrix, etc.; for another example, the multiple air outlet holes 501 are arranged to form various shapes and patterns, which is beneficial to improving the aesthetics of the appearance of the humidification device 500.

[0168] In some embodiments, the top of the humidification shell 510 is connected to the water injection pipe 540 to achieve communication between the water injection pipe 540 and the water storage chamber 511. Such a configuration allows a shorter water injection pipe 540 to be configured, which can not only reduce material costs, but also avoid the problem of poor stability caused by an excessively long water injection pipe 540.

[0169] Combination Fig.11 and Fig.12 In some embodiments, the humidifying device 500 includes an atomizer 520, which can be disposed on the bottom wall of the humidifying housing 510, so as to use up the water in the water storage chamber 511 and avoid the water in the water storage chamber 511 from remaining for many times, which may easily breed bacteria.

[0170] In some embodiments, the atomizer 520 can also be installed at other positions of the humidification shell 510, and there is a gap between the atomizer 520 and the bottom wall of the humidification shell 510. At this time, water on the bottom wall of the humidification shell 510 can be guided to the atomizer 520 by setting water-absorbing components such as absorbent cotton.

[0171] In some embodiments, the humidification device 500 may include a humidification fiber, at least part of which is immersed in the water in the water storage chamber 511, and at least part of which is located above the water surface of the water storage chamber 511. In this way, humidification is achieved by blowing air through the part of the humidification fiber above the water surface with the help of a fan.

[0172] In some embodiments, the humidification device 500 includes a second fan 530, which is installed inside the humidification housing 510 and located at the top of the water storage chamber 511. The second fan 530 is configured to blow the water mist generated by the atomizer 520 into the storage space.

[0173] In some embodiments, the second fan 530 and the air outlet 501 are arranged relative to each other along the thickness direction of the humidification shell 510 (corresponding to the Y-axis direction in the accompanying drawings), so that the second fan 530 can blow high-humidity air into the storage space through the air outlet 501, thereby improving the humidification efficiency.

[0174] In some embodiments, the humidifying device 500 also includes a liquid level sensor 550, which is disposed on the bottom wall of the water storage chamber 511. The liquid level sensor 550 is configured to detect the water level of the water storage chamber 511. When the water level of the water storage chamber 511 detected by the liquid level sensor 550 is lower than a set value, the control device of the refrigerator controls the prompt component to send a prompt message to prompt the user to replenish water in time.

[0175] Among them, the prompt components of the refrigerator include but are not limited to speakers, light prompters, display screens, etc.
