Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a drawer assembly and a refrigeration device. Background Art

[0002] Refrigeration equipment is a mechanical device used for refrigeration, which stores food or other items by maintaining a constant low temperature and cold state. Common refrigeration equipment includes refrigerators, freezers, etc. As user needs increase, refrigeration equipment usually also has an ice-making function. In the related art, a refrigeration equipment with an ice-making function is provided with an ice maker and a water storage box that provides water for the ice maker. At the same time, a fresh-keeping room is also provided in the refrigeration equipment, and the water storage box can also be used to humidify the fresh-keeping room to meet the environmental humidity requirements of the items stored in the fresh-keeping room.

[0003] However, in the related art, the water storage box and the fresh-keeping room installed in the refrigeration equipment will occupy more storage space of the refrigeration equipment, thereby causing the storage space to be reduced and affecting the user experience. Utility Model Content

[0004] The present application provides a drawer assembly and a refrigeration device, which can enable the drawer assembly to form an integrated structure, thereby reducing the occupation of storage space in the refrigeration device and improving the user experience.

[0005] The technical solutions adopted in this application are as follows:

[0006] According to the first aspect disclosed in the present application, a drawer assembly is provided. The drawer assembly includes a water storage box, a drawer body, a humidity sensor and a humidity adjustment device. The water storage box is provided with a liquid storage cavity. The drawer body is provided with a storage cavity. The drawer body is at least partially engaged with the water storage box, so that the drawer body can slide relative to the water storage box, so that the drawer body has a storage state and a pull-out state. In the process of switching the drawer body from the storage state to the pull-out state, the drawer body slides along the water storage box and protrudes from the water storage box to open the storage cavity, which is convenient for the user to take and put items in the storage cavity. The humidity sensor is arranged in the storage cavity, which is used to detect the humidity in the storage cavity. The humidity adjustment device is connected between the water storage box and the drawer body to adjust the humidity in the storage cavity according to the humidity signal in the storage cavity obtained by the humidity sensor.

[0007] The drawer assembly provided by the present application has the following beneficial effects:

[0008] When the drawer assembly provided by the present application is used, the drawer assembly can be installed in a refrigeration device. At this time, the drawer body and the water storage box are interlocked with each other to be in a storage state. When the user opens the door of the refrigeration device and needs to place items in the storage cavity of the drawer body, the user can slide the drawer body along the water storage box so that the drawer body protrudes from the water storage box, thereby facilitating the opening of the storage cavity and placing the items in the storage cavity. After the user completes the taking and placing of items, the user can slide the drawer body along the water storage box to reset it and close the door of the refrigeration device. At the same time, in the process of storing items in the drawer body, the humidity sensor can detect the humidity in the storage cavity in real time, and the humidity sensor transmits the humidity signal in the storage cavity obtained to the humidity regulating device. A humidity threshold is preset in the humidity regulating device. When the humidity signal received by the humidity regulating device is lower than the humidity threshold, the humidity regulating device transmits the moisture in the liquid storage cavity in the water storage box to the storage cavity to humidify the storage cavity and increase the environmental humidity of the storage cavity.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of this embodiment, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] In this application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0041] Refrigeration equipment is a mechanical device for refrigeration, which stores food or other items by maintaining a constant low-temperature cold state. Common refrigeration equipment includes refrigerators, freezers, etc. With the increase in user demand, refrigeration equipment usually also has an ice-making function. In the relevant technology, taking a refrigerator as an example, a refrigerator with an ice-making function is provided with an ice maker and a water box that provides water for the ice maker. The water box is usually arranged in the cold storage area of ​​the refrigerator to prevent the water source in the water box from freezing. However, the space in the cold storage area of ​​the refrigerator is limited, and placing the water box in the cold storage area will undoubtedly occupy part of the space in the cold storage area, reducing the storage space in the cold storage area. In addition, in the relevant technology, a fresh-keeping area can also be set in the cold storage area of ​​the refrigerator, and the humidity of the fresh-keeping area can be adjusted according to the needs of storing items, but this also requires the installation of a humidity regulator in the cold storage area, resulting in further reduction of the storage space in the cold storage area, affecting the user experience.

[0042] like Figure 1 and Figure 2 As shown, the present application provides a refrigeration device 1, including a housing 10, a compressor 20, a condenser 30, an evaporator 40 and an expansion valve 50. The housing 10 includes a shell assembly 11, a freezing chamber 13, a refrigerating chamber 14 and a door assembly 12. The freezing chamber 13 and the refrigerating chamber 14 are respectively arranged in the shell assembly 11. The door assembly 12 includes a first door 12a and a second door 12b. The first door 12a is rotatably connected to the housing assembly 11 to open or close the freezing chamber 13. The second door 12b is rotatably connected to the housing assembly 11 to open or close the refrigerating chamber 14. The compressor 20, the condenser 30, the evaporator 40 and the expansion valve 50 are respectively arranged in the housing assembly 11, and at least part of the evaporator 40 is arranged in the freezing chamber 13.

[0043] Combination Figure 3 As shown, when the refrigeration device 1 is in operation, the compressor 20 outputs a high-temperature and high-pressure gaseous refrigerant to the condenser 30, and the high-temperature and high-pressure gaseous refrigerant is condensed into a medium-temperature and high-pressure refrigerant through the condenser 30. The medium-temperature and high-pressure refrigerant passes through the expansion throttling effect of the expansion valve 50, so that the pressure and temperature of the refrigerant are further reduced, and the low-temperature and low-pressure liquid refrigerant flows out of the expansion valve 50 to the evaporator 40. The low-temperature and low-pressure liquid refrigerant evaporates into a gaseous refrigerant in the evaporator 40. At least part of the evaporator 40 is arranged in the freezing chamber 13, so that the refrigerant absorbs a large amount of heat in the freezing chamber 13 during the evaporation process, thereby reducing the temperature in the freezing chamber 13, making it easier to use the freezing chamber 13 to freeze items and realize the refrigeration of the refrigeration device 1. The refrigerant coming out of the evaporator 40 is replenished back to the compressor 20 to form a refrigerant circuit. In this way, the refrigerant circulates continuously in the refrigerant circuit to maintain the freezing environment of the freezing chamber 13 (for example, less than -1°C).

[0044] See you later Figure 2As shown, a temperature control air duct 15 is provided between the refrigerating chamber 14 and the freezing chamber 13, so as to transport part of the cold air from the freezing chamber 13 to the refrigerating chamber 14 through the temperature control air duct 15, so as to reduce or maintain the low temperature environment of the refrigerating chamber 14 (for example, 2°C to 8°C).

[0045] like Figure 2 As shown, in some embodiments, along the height direction (Z-axis direction) of the refrigeration device 1, the freezing chamber 13 is arranged below the refrigerating chamber 14. The refrigeration device 1 also includes a temperature control fan (not marked) arranged in the housing assembly 11. The air inlet end or the air outlet end of the temperature control fan is connected to the temperature control air duct 15, which is used to transport part of the cold air in the freezing chamber 13 to the refrigerating chamber 14.

[0046] In some embodiments, the outer wall of the freezing chamber 13 is covered with an insulation layer (not shown) to separate the evaporator 40 from the compressor 20 and the condenser 30. The refrigeration device 1 also includes an air-cooling heat dissipation component (not shown) disposed in the housing component 11, and the air-cooling heat dissipation component can at least dissipate heat for the condenser 30.

[0047] In some embodiments, the housing assembly 11 further includes a fresh-keeping room 16 disposed in the housing assembly 11. Along the height direction of the refrigeration device 1, the fresh-keeping room 16 can be disposed between the refrigerator compartment 14 and the freezer compartment 13. In addition, in other embodiments, the fresh-keeping room 16 can also be disposed in the refrigerator compartment 14. For example, a drawer that can be pulled out and moved is disposed in the refrigerator compartment 14. The humidity and temperature of this part of the drawer are individually controlled, and this part of the drawer can be used as the fresh-keeping room 16.

[0048] Further, in order to meet the needs of users for using ice cubes, such as Figure 4 As shown, in some embodiments, the refrigeration device 1 further includes an ice-making device 60 for making ice cubes. The ice-making device 60 includes an ice-making machine 61 and a liquid injection component 62. Usually, the ice-making machine 61 is arranged in the freezing chamber 13, and the liquid injection component 62 is used to inject liquid required for making ice cubes into the ice mold device of the ice-making machine 61. In one example, a water storage box is arranged in the cold storage chamber 14 of the refrigeration device 1, and the liquid injection component 62 includes a liquid injection pipe, one end of which is connected to the water storage box, and the other end of the liquid injection pipe is connected to the ice-making machine 61 along the height direction of the refrigeration device 1.

[0049] Optionally, the liquid injection component 62 further includes a switch valve (not shown), which may also be disposed in the water storage box, for opening the liquid injection component 62 to inject liquid into the ice maker 61, or closing the liquid injection component 62. In addition, in some embodiments, the liquid injection component 62 may further include a water receiving assembly for connecting to an external liquid injection pipe.

[0050] See also Figures 5 to 8As shown, in order to increase the storage space in the refrigeration device 1, this embodiment also provides a drawer assembly 100. The drawer assembly 100 includes a water storage box 110, a drawer body 120, a humidity sensor 130 and a humidity adjustment device 140. Among them, the water storage box 110 is provided with a liquid storage cavity 111. The drawer body 120 is provided with a storage cavity 121. The drawer body 120 and the water storage box 110 are at least partially embedded, so that the drawer body 120 can slide relative to the water storage box 110, so that the drawer body 120 has a storage state and a withdrawal state. In the process of switching the drawer body 120 from the storage state to the withdrawal state, the drawer body 120 slides along the water storage box 110 and protrudes from the water storage box 110, so as to open the storage cavity 121, which is convenient for users to take and put items in the storage cavity 121. The humidity sensor 130 is arranged in the storage cavity 121, and is used to detect the humidity in the storage cavity 121. The humidity adjustment device 140 is connected between the water storage box 110 and the drawer body 120 to adjust the humidity in the storage cavity 121 according to the humidity signal in the storage cavity 121 obtained by the humidity sensor 130 .

[0051] When the drawer assembly 100 provided by the present application is used, the drawer assembly 100 can be installed in the refrigeration device 1. At this time, the drawer body 120 and the water storage box 110 are interlocked with each other to be in a storage state. When the user opens the door of the refrigeration device 1 and needs to place items in the storage cavity 121 of the drawer body 120, the user can slide the drawer body 120 along the water storage box 110 so that the drawer body 120 protrudes from the water storage box 110, thereby facilitating the opening of the storage cavity 121 and placing the items in the storage cavity 121. After the user completes the taking and placing of items, the user can slide the drawer body 120 along the water storage box 110 to reset it and close the door of the refrigeration device 1. At the same time, in the process of storing items in the drawer body 120, the humidity sensor 130 can detect the humidity in the storage cavity 121 in real time, and the humidity sensor 130 transmits the humidity signal in the storage cavity 121 obtained to the humidity adjustment device 140. A humidity threshold is preset in the humidity regulating device 140. When the humidity signal received by the humidity regulating device 140 is lower than the humidity threshold, the humidity regulating device 140 transfers the moisture in the liquid storage chamber 111 in the water storage box 110 to the storage chamber 121 to humidify the storage chamber 121 and increase the ambient humidity of the storage chamber 121.

[0052] It should be noted that the drawer assembly 100 can be installed in the refrigeration device 1 as a fresh-keeping room 16. Among them, the drawer assembly 100 can be arranged in the refrigerator compartment 14 of the refrigeration device 1, or when the refrigeration device 1 is provided with a variable temperature room, the drawer assembly 100 can also be arranged in the variable temperature room. The drawer assembly 100 can form an environmental humidity that is the same as that of the refrigerator compartment 14, the same as that of the variable temperature room, or an environmental humidity between the refrigerator compartment 14 and the freezer compartment 13, etc., which is not limited in this application. In addition, a high humidity area or a dry area can also be formed in the drawer assembly 100, which is not limited in this application.

[0053] The storage chamber 121 of the drawer body 120 can be used to store items that have high requirements for environmental humidity, and can also store other items according to user needs, which is not limited in this application. The water storage box 110 is provided with a water injection port 115, and the water storage box 110 is used to store liquid. The liquid stored in the water storage box 110 can be used to humidify the gas in the liquid storage chamber 111, so that the moisture in the liquid storage chamber 111 is transported to the storage chamber 121 of the drawer body 120 through the humidity adjustment device 140 to increase the environmental humidity in the storage chamber 121. In addition, the water storage box 110 is equipped with a water pump 114 and a liquid suction pipe 116, one end of the liquid suction pipe 116 extends into the liquid storage chamber 111 of the water storage box 110, and the other end of the liquid suction pipe 116 is connected to the liquid injection pipe of the ice maker 61. The water pump 114 acts on the liquid suction pipe 116 to supply the water source in the liquid storage chamber 111 of the water storage box 110 to the ice maker 61 for making ice, etc. Thus, the water storage box 110 can humidify the environment in the drawer body 120 and provide water for the ice maker 61. By using one water storage box 110 to realize two functions, the number of water storage boxes 110 arranged in the refrigeration device 1 can be reduced to save functional space in the refrigeration device 1.

[0054] At the same time, the drawer body 120 and the water storage box 110 are at least partially embedded, so that the drawer body 120 can slide relative to the water storage box 110. In this way, when the drawer body 120 and the water storage box 110 are installed, there is a mutually embedded part between the two. The embedded part can not only realize the relative sliding of the two, but also make the layout of the drawer body 120 and the water storage box 110 integrated. Compared with the separate installation of the drawer body 120 and the water storage box 110, on the one hand, the present application does not need to install an additional base for the drawer body 120 to slide, which simplifies the installation structure of the drawer assembly 100 and reduces the required installation space. On the other hand, the present application integrates the drawer body 120 and the water storage box 110, reducing the assembly gap between the two. Therefore, in this way, the space occupied by the drawer assembly 100 in the cold storage chamber 14 is reduced, and the storage space in the cold storage chamber 14 is increased, and the installation efficiency of the drawer assembly 100 is also improved.

[0055] It should also be noted that the humidity sensor 130 is a device for measuring the humidity in the air. The humidity sensor 130 may include a resistive humidity sensor 130, a capacitive humidity sensor 130, an infrared humidity sensor 130, a micromechanical humidity sensor 130, an optical humidity sensor 130, and other humidity sensors 130. This application does not limit this.

[0056] Therefore, compared with the related art, when the refrigeration equipment is provided with an ice maker and a fresh-keeping bin, the water storage box and the drawer body in the related art are usually set as independent structures, and the two are installed side by side from left to right, which not only has a large installation gap, but also requires an additional base for the drawer body to slide, resulting in more storage space in the refrigeration equipment being occupied, and the user's experience is poor. However, when the drawer assembly 100 provided in the present application is installed in the refrigeration equipment 1, the drawer body 120 can not only use the water storage box 110 to humidify the storage cavity 121 to extend the storage time of the items. The drawer body 120 can also form an integrated structure by partially fitting with the water storage box 110, so that the drawer body 120 can slide relative to the water storage box 110, and there is no need to install an additional base for the drawer body 120 to slide on the drawer body 120, thereby reducing the occupation of the storage space in the refrigeration equipment 1, which is conducive to improving the user experience.

[0057] In some embodiments, in order to facilitate the water storage box 110 and the drawer body 120 to form an integrated structure, the water storage box 110 is provided with a groove 112 that is recessed into the liquid storage cavity 111, and the groove 112 has at least one opening that communicates the inside and outside of the groove 112. The drawer body 120 is disposed in the groove 112 and is slidably connected to the inner wall of the groove 112. In the storage state, the drawer body 120 is disposed in the groove 112. In the withdrawn state, the drawer body 120 slides out of the groove 112 through the opening.

[0058] It should be noted that when the water storage box 110 is provided with a groove 112, the drawer body 120 can be directly placed in the groove 112 to complete the assembly of the drawer body 120 and the water storage box 110. In addition, the drawer body 120 can limit its own sliding direction by using the extension direction of the groove 112 to improve the sliding stability of the drawer body 120. Thus, the integrated structure of the water storage box 110 and the drawer body 120 is realized.

[0059] In addition, when the groove 112 is provided with an opening connecting the inside and the outside of the groove 112, when the drawer body 120 is in the storage state, the drawer body 120 is disposed in the groove 112, and the inner wall of the groove 112 can also be used to shield the storage cavity 121 of the drawer body 120 to reduce moisture loss or temperature fluctuation in the storage cavity 121. When the drawer body 120 is in the withdrawn state, the drawer body 120 extends from the groove 112 to open the storage cavity 121, so that the user can take items from the storage cavity 121.

[0060] Of course, in other embodiments, the groove 112 may also be provided with a plurality of openings, which is not limited in the present application. For example, the groove 112 is provided with two openings, which are respectively arranged on two sides of the groove 112 that are relatively spaced along the width direction 110b of the water storage box, and the drawer body 120 can slide relative to the water storage box 110 along the width direction 110b of the water storage box. Alternatively, the groove 112 may also be provided with three openings, wherein two openings are respectively arranged on two sides of the groove 112 that are relatively spaced along the width direction 110b of the water storage box, and one opening is arranged at the top of the water storage box 110. In this case, the drawer body 120 may also be provided with a separate cover 122, which is used to cover the storage cavity 121 of the drawer body 120 to reduce moisture loss or temperature fluctuation in the storage cavity 121.

[0061] See also Figure 6 and Figure 7 In some embodiments, in order to make the drawer body 120 move smoothly, the inner wall of the groove 112 is provided with a first connection part 117, and the outer wall of the drawer body 120 is provided with a second connection part 125, and the first connection part 117 is slidably connected with the second connection part 125. When the drawer body 120 slides relative to the water storage box 110, the first connection part 117 and the second connection part 125 can be used as a guide rail to guide the movement of the drawer body 120 relative to the water storage box 110, thereby improving the movement accuracy and stability of the drawer body 120. Optionally, one of the first connection part 117 and the second connection part 125 is set as a protrusion, and the other is set as a groove 112, and the protrusion is embedded in the groove 112 to form a guide rail. The structure of the first connection part 117 and the second connection part 125 is not limited to the cooperation between the groove 112 and the protrusion, as long as it can meet the use requirements, the present application will not repeat it.

[0062] In some embodiments, to meet the user's usage requirements, the drawer assembly 100 is provided with at least two drawer bodies 120, and the water storage box 110 is provided with at least two grooves 112, each groove 112 is arranged at intervals along the length direction 110a of the water storage box, and each drawer body 120 is respectively arranged in each groove 112, and the drawer body 120 can slide along the width direction 110b of the water storage box to switch between the storage state and the extraction state.

[0063] It should be noted that Figure 7 The X direction is set as the length direction 110a of the water storage box, Figure 7The Y direction is set as the width direction 110b of the water storage box. When there are multiple drawer bodies 120, there is usually a gap between two adjacent drawer bodies 120, and this part of the gap space is usually wasted. In the present application, when the water storage box 110 and the drawer body 120 are installed in coordination, the water storage box 110 forms at least two grooves 112, and a protruding space is formed between the side walls 112a of the two adjacent grooves, which can just fill the gap between the two drawer bodies 120. As a result, the water storage box 110 and the drawer body 120 can not only form an integrated layout, but also can use the gap space between the two drawer bodies 120 to increase the liquid storage cavity 111 space of the water storage box 110, so as to store more water sources or form more moisture storage space.

[0064] In addition, the groove 112 of the water storage box 110 extends along the length direction 110a of the water storage box, and the drawer body 120 slides along the width direction 110b of the water storage box, which can avoid movement interference between the drawer bodies 120, so that the user can flexibly open or close each drawer body 120.

[0065] See also Figure 7 and Figure 8 In some embodiments, in order to facilitate adaptation to drawer bodies 120 of different sizes, part of the wall surface of the water storage box 110 is recessed toward the inside of the liquid storage cavity 111 along the depth direction 110c of the water storage box to form a groove 112.

[0066] As an example, part of the top wall of the water storage box 110 is recessed into the liquid storage cavity 111 to form a U-shaped groove, and the two ends of the U-shaped groove spaced apart along the width direction 110b of the water storage box are open ends. Thus, when drawer bodies 120 of different heights can be placed in the U-shaped groove, the water storage box 110 can be installed with drawer bodies 120 of different heights, thereby improving the versatility of the water storage box 110.

[0067] See also Figure 8 and Fig. 9 In some embodiments, in order to facilitate the adjustment of the humidity in the storage cavity 121 in the drawer body 120, the liquid storage cavity 111 includes a first cavity 111a and a second cavity 111b that are connected to each other. The first cavity 111a is disposed between the inner wall of the water storage box 110 and the bottom wall 112b of the groove, and the first cavity 111a is used to store liquid. The second cavity 111b is disposed between the inner wall of the water storage box 110 and the side wall 112a of the groove, and the side wall 112a of the groove is provided with a first air vent 113 that is connected to the second cavity 111b. The drawer body 120 is provided with a second air vent 123 that is connected to the storage cavity 121, and the second air vent 123 is disposed opposite to the first air vent 113. The humidity adjustment device 140 is connected between the first air vent 113 and the second air vent 123.

[0068] It should be noted that the first chamber 111a is used to store water for use by the ice maker 61. At the same time, the water in the first chamber 111a can humidify the air in the second chamber 111b and increase the humidity of the gas in the second chamber 111b. In addition, the first chamber 111a is arranged between the bottom wall 112b of the groove and the inner wall of the water storage box 110. When the drawer body 120 is placed in the groove 112, since there is a water source in the first chamber 111a, the water in the first chamber 111a can absorb part of the heat. Therefore, after the drawer body 120 and the water storage box 110 are assembled, the water in the water storage box 110 can absorb the heat of the storage cavity 121 of the drawer body 120, so that the storage cavity 121 can be cooled down and the external heat can be isolated from entering the storage cavity 121, so as to reduce the temperature change in the storage cavity 121 and improve the storage effect of the storage cavity 121 on the items.

[0069] The second chamber 111b is used to transfer moisture to the storage chamber 121 to increase the humidity in the storage chamber 121. When there are multiple drawer bodies 120, the second chamber 111b can be arranged between the side walls 112a of two adjacent grooves. When there is only one drawer body 120, the second chamber 111b can be arranged between the side wall 112a of the groove and the side wall of the water storage box 110. This arrangement can separate the first chamber 111a from the second chamber 111b to prevent the liquid in the first chamber 111a from entering the second chamber 111b and affecting the humidification effect of the storage chamber 121.

[0070] The number of the first air vent 113 and the second air vent 123 can be set to one or more, respectively, and this application does not limit it. At the same time, the first air vent 113 and the second air vent 123 can be set to a variety of shapes such as round, square, triangular, and special shapes, respectively, and this application does not limit it. In addition, the first air vent 113 and the second air vent 123 can be aligned when the drawer body 120 is in the storage state, so there is no need to connect an additional pipe between the first air vent 113 and the second air vent 123, simplifying the installation structure of the drawer assembly 100.

[0071] In some embodiments, the humidity regulating device 140 is disposed in the second chamber 111b to save space occupied by the drawer assembly 100. Of course, in other embodiments, the humidity regulating device 140 may also be disposed in the storage cavity 121 of the drawer body 120, or in other installation locations, which is not limited in this application.

[0072] As an example, the humidity regulating device 140 includes a first fan 141, a first damper 142, a first flow guide 143 and a humidity controller, the first fan 141 is fixed to the inner wall of the second chamber 111b, the first damper 142 is arranged at the first air outlet 113, the first flow guide 143 is arranged between the first fan 141 and the first damper 142, and the first fan 141 and the first damper 142 are electrically connected to the humidity controller respectively.

[0073] When adjusting the humidity in the storage cavity 121 of the drawer body 120, the humidity in the storage cavity 121 is detected in real time by the humidity sensor 130, and the humidity sensor 130 transmits the humidity signal in the storage cavity 121 obtained to the humidity controller. A humidity threshold is preset in the humidity controller. When the humidity signal received by the humidity controller is lower than the humidity threshold, the humidity controller opens the first damper 142, so that the first air outlet 113 is connected with the second air outlet 123, thereby connecting the liquid storage cavity 111 with the storage cavity 121. At the same time, the humidity controller starts the first fan 141, and the first fan 141 blows the moisture in the second chamber 111b to flow. The flowing moisture passes through the first guide member 143 and is guided to the first damper 142, so that the moisture in the second chamber 111b can flow through the first air outlet 113 and the second air outlet 123 in sequence, and finally transmitted to the storage cavity 121. Thereby, the storage cavity 121 is humidified and the environmental humidity of the storage cavity 121 is increased.

[0074] It should be noted that see Figures 7 to 10 When the drawer body 120 is provided with one, the first damper 142 may include an air outlet to connect the storage cavity 121 with the liquid storage cavity 111 by controlling the switch of the air outlet. When the drawer body 120 is provided with multiple air outlets, the first damper 142 may include two air outlets. For example, when the drawer body 120 is provided with multiple air outlets, the first damper 142 is arranged between the side walls 112a of two adjacent grooves. The two air outlets of the first damper 142 respectively control a second chamber 111b of the water storage box 110 to be connected with the storage cavity 121 of two adjacent drawer bodies 120. That is, as Fig.10 The first damper 142 is shown, and the first damper 142 includes a first air outlet 142a and a second air outlet 142b. The first air outlet 142a controls the communication between the second chamber 111b and the left drawer body 120, and the second air outlet 142b controls the communication between the second chamber 111b and the right drawer body 120. The first air outlet 142a and the second air outlet 142b operate independently without interfering with each other, so that the humidity of each drawer body 120 can be adjusted independently.

[0075] In some embodiments, in order to facilitate the drainage of moisture blown by the first fan 141 into the storage cavity 121, the first guide member 143 includes a first baffle 143a and a second baffle 143b, and the first baffle 143a and the second baffle 143b are spaced apart on both sides of the first air outlet 113, the first baffle 143a is arranged opposite to the first fan 141, and the second baffle 143b is arranged between the first fan 141 and the first baffle 143a, so that the gas blown by the first fan 141 flows to the first air outlet 113 through the first baffle 143a and the second baffle 143b in sequence.

[0076] It should be noted that the first baffle 143a and the second baffle 143b are respectively connected between the side walls 112a of two adjacent grooves. Since the second baffle 143b is arranged between the first baffle 143a and the first fan 141, in order to facilitate the drainage of the moisture blown out by the first fan 141 into the storage chamber 121, the length of the second baffle 143b can be shorter than the first baffle 143a. Specifically, the distance between the bottom wall of the second baffle 143b and the bottom wall of the liquid storage chamber 111 is greater than the distance between the bottom wall of the first baffle 143a and the bottom wall of the liquid storage chamber 111, that is, a is greater than b. At this time, the moisture blown out by the first fan 141 first contacts the first baffle 143a and flows along the first baffle 143a. Since the first baffle 143a is connected between the side walls 112a of two adjacent grooves, after the moisture is blocked by the first baffle 143a, part of the moisture will flow back in the opposite direction. At this time, the second baffle 143b can block this part of the moisture that flows back and guide this part of the moisture that flows back to the first damper 142. Therefore, through the guidance of the moisture by the first baffle 143a and the second baffle 143b, the moisture blown by the first fan 141 can flow smoothly into the storage chamber 121, so as to improve the humidification efficiency of the storage chamber 121. Moreover, the second baffle 143b is arranged between the first fan 141 and the first baffle 143a, so that the first fan 141 is arranged outside the first baffle 143a and the second baffle 143b, so that the first fan 141 can blow more moisture in the second chamber 111b to flow, thereby improving the humidification effect of the storage chamber 121.

[0077] In addition, in other embodiments, the lengths of the first baffle 143a and the second baffle 143b can be set to be the same, but a gap can be opened in the second baffle 143b facing the first fan 141, so that the moisture blown out by the first fan 141 can flow through the gap through the first baffle 143a and the second baffle 143b in sequence, and finally flow into the storage cavity 121.

[0078] Of course, in other embodiments, the first fan 141 may also be disposed between the first baffle 143a and the second baffle 143b, which is not limited in the present application.

[0079] In some embodiments, in order to facilitate the adjustment of the temperature in the storage cavity 121 of the drawer body 120, the drawer body 120 is provided with a third air outlet 124 connected to the storage cavity 121, and the drawer assembly 100 further includes a temperature sensor and a temperature adjustment device. The temperature sensor is arranged in the storage cavity 121 to detect the temperature in the storage cavity 121. The temperature adjustment device is arranged at the third air outlet 124 to adjust the temperature in the storage cavity 121 according to the temperature signal in the storage cavity 121 obtained by the temperature sensor.

[0080] It should be noted that when the drawer assembly 100 is installed in the refrigeration equipment 1, the third air outlet 124 can be used to communicate with the temperature control air duct 15, so as to guide part of the cold air transported from the freezer chamber 13 to the refrigerator chamber 14 through the temperature control air duct 15 to the storage cavity 121 of the drawer body 120, so as to reduce or maintain the low temperature environment in the storage cavity 121, and extend the shelf life and preservation effect of the items in the storage cavity 121.

[0081] The temperature sensor includes a digital thermometer, an infrared temperature sensor, and the like, which are not limited in this application. In addition, the temperature sensor and the humidity sensor 130 can also be integrated into a temperature and humidity sensor 130, which is not described in detail in this application. The temperature sensor can be arranged on the inner wall of the storage cavity 121, or, when the drawer body 120 is provided with a cover 122 for shielding the storage cavity 121, the temperature sensor can also be arranged on the inner wall of the cover 122 facing the storage cavity 121 to avoid the items in the storage cavity 121 from damaging the temperature sensor.

[0082] As an example, the temperature adjustment device includes a second fan, a second air door, a second air guide and a temperature controller, the second fan is arranged outside the storage cavity 121, the second air door is arranged at the third air outlet 124, the second air guide is arranged between the second fan and the second air door, and the second fan and the second air door are electrically connected to the temperature controller respectively.

[0083] When adjusting the temperature in the storage cavity 121 of the drawer body 120, the temperature in the storage cavity 121 is detected in real time by using a temperature sensor, and the temperature sensor transmits the acquired temperature signal in the storage cavity 121 to the temperature controller. A temperature threshold is preset in the temperature controller. When the temperature signal received by the temperature controller is lower than the temperature threshold, the temperature controller opens the second air door, so that the third air outlet 124 is connected to the temperature control air duct 15, thereby connecting the temperature control air duct 15 and the storage cavity 121. At the same time, the temperature controller starts the second fan, and the second fan guides part of the cold air transported from the freezer compartment 13 to the refrigerator compartment 14 into the storage cavity 121 of the drawer body 120, thereby cooling the storage cavity 121 or maintaining a low temperature environment.

[0084] It should be understood that the present application is not limited to the precise structures that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present application is limited only by the appended claims.

[0085] In addition, the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.
