DETAILED DESCRIPTION

[0059] As shown in the background technology, since the distances from different air outlets to the return air outlet are different, when the air volumes of each air outlet are the same, the air outlet close to the return air outlet has a shorter return air path and a faster return air speed, while the air outlet far from the return air outlet has a longer return air path and a smaller air volume. It is not easy to return the air far away to the return air outlet, resulting in poor air uniformity in the second chamber.

[0060] In order to solve the above technical problems, the fruit and vegetable cultivation equipment in the present application distributes the air volume according to the return air distance, which is conducive to the smooth return of air at various positions and improves the uniformity of the air in the second chamber.

[0067] 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.

[0068] Figure 1 This is a schematic diagram of the structure of the fruit and vegetable cultivation equipment provided in the embodiment of the present application. Figure 2This is a schematic diagram of the structure of the fruit and vegetable cultivation equipment provided in the embodiment of the present application after the door body is removed. Figure 3 This is a schematic diagram of the structure of the fruit and vegetable cultivation equipment provided in an embodiment of the present application after removing the door body and the outer shell.

[0069] See also Figures 1 to 3 As shown, the fruit and vegetable cultivation device provided in the embodiment of the present application can be formed of a box body 100 and a door body 300 to form an appearance. The box body 100 has an inner cavity, and the inner cavity has an opening. The door body 300 is used to open or close the opening.

[0070] In this embodiment, a hydroponic component 200 is disposed in the housing 100. The number of the hydroponic components 200 is at least one. When the number of the hydroponic components 200 is at least two, at least two hydroponic components 200 can be arranged at intervals along the length direction of the housing 100, thereby improving the space utilization of the housing 100. Exemplarily, the number of the hydroponic components 200 can be multiple, and the multiple hydroponic components 200 are arranged at intervals along the length direction of the housing 100. For example, the number of the hydroponic components 200 is four. The length direction of the housing 100 is the direction shown by the Z axis.

[0071] The hydroponic assembly 200 is configured to hold nutrient solution and fruit and vegetable seedlings. For example, the hydroponic assembly 200 can cultivate leafy vegetables such as lettuce and edible fungus and some fruits such as strawberries, melons, and tomatoes. The liquid level of the nutrient solution in the hydroponic assembly 200 can be set according to the type of fruit and vegetable and the requirements of the growth period.

[0072] In some embodiments, in order to facilitate observation and operation of fruits and vegetables, the hydroponic component 200 is slidably connected to the box 100, so that the hydroponic component 200 can be moved to the outside of the box 100 for user operation.

[0073] In some embodiments, the fruit and vegetable cultivation equipment includes a liquid supply system 700, which can be used to circulate nutrient solution for the hydroponic component 200. That is, after the nutrient solution of the liquid supply system 700 flows to the hydroponic component 200, it flows through the flow channel of the hydroponic component 200 and returns to the liquid supply system 700.

[0074] In some embodiments, in order to provide the light required for the growth of fruits and vegetables, the fruit and vegetable cultivation device is provided with a lighting assembly 800, and the lighting assembly 800 is arranged above the hydroponic assembly 200. Exemplarily, the amount of light irradiated by the lighting assembly 800 can be set to be similar to sunlight, and the light amount and irradiation time that are most suitable for the cultivated fruits and vegetables can be set.

[0075] In some embodiments, when the number of the hydroponic components 200 is at least two, the at least two hydroponic components 200 can be spaced apart along the length direction of the housing 100 , and the at least two lighting components 800 are disposed in one-to-one correspondence with the at least two hydroponic components 200 .

[0076] In some embodiments, the lighting assembly 800 can be disposed at the bottom of the hydroponic assembly 200 above the corresponding hydroponic assembly 200, thereby eliminating the need to additionally provide a mounting structure for the lighting assembly 800 in the housing 100, thereby saving space and improving space utilization.

[0077] In some embodiments, the fruit and vegetable cultivation equipment includes an air conditioning device, which may include at least one of a temperature regulating device, a humidity regulating device, and a carbon dioxide regulating device, so as to regulate the air condition in the box to meet the growth requirements of fruits and vegetables. For example, the temperature regulating device includes a refrigeration system 400 and a heating element. The carbon dioxide regulating device may include a carbon dioxide generator.

[0078] In some embodiments, a display component is disposed outside the box 100, and the display component can intuitively display the status of the fruit and vegetable cultivation device. In addition, in order to facilitate the user to set parameters, the fruit and vegetable cultivation device also includes a control panel, and the control panel is electrically connected to the controller. The control panel is a touch panel, which can be disposed on the door 300, or can be disposed on the top of the box 100.

[0079] In some embodiments, the fruit and vegetable cultivation equipment includes a fan, which is disposed in the box 100 . The fan drives air flow, thereby realizing air circulation in the box 100 .

[0080] In some embodiments, the fruit and vegetable cultivation equipment includes a fan, which is disposed in the box 100. The fan drives air flow, thereby realizing circulation between the box 100 and external air.

[0081] [Box structure]

[0082] Figure 4 This is a schematic diagram of the structure of the first type of box in the fruit and vegetable cultivation equipment provided in an embodiment of the present application.

[0083] See also Figure 4 As shown, in some embodiments, air circulation is achieved in the box 100 , and the box 100 is configured with a first chamber 110 and a second chamber 120 .

[0084] The housing 100 is configured with a first return air port 1621 and a first air outlet 1622. The first return air port 1621 is in communication with the first chamber 110 and the second chamber 120. The first air outlet 1622 is in communication with the first chamber 110 and the second chamber 120.

[0085] The fan 600 is disposed in the first chamber 110 or the second chamber 120 . The fan 600 rotates, thereby driving the air in the first chamber 110 to flow into the second chamber 120 through the first air outlet 1622 , and the air in the second chamber 120 to flow into the first chamber 110 through the first return air outlet 1621 .

[0086] In some embodiments, in order to improve space utilization, the hydroponic component 200 is disposed in the second chamber 120 , and the fan 600 is disposed in the first chamber 110 .

[0087] In some embodiments, in order to adjust the air in the second chamber 120 to meet the needs of fruit and vegetable growth, an air conditioning device is provided in the first chamber 110 .

[0088] Specifically, the air conditioning device may include a refrigeration system, and the evaporator 410 of the refrigeration system is arranged in the first chamber 110 to cool the air in the first chamber 110. The cooled air flows into the second chamber 120 under the action of the fan 600.

[0089] It is understandable that the evaporator 410 of the refrigeration system can also be used to reduce the humidity of the air in the first chamber 110 , and the dehumidified air flows into the second chamber 120 under the action of the fan 600 .

[0090] In some embodiments, the housing 100 includes a compressor compartment, and the compressor and condenser of the refrigeration system are located in the compressor compartment. The compressor compartment is located at the bottom of the housing 100. Therefore, in order to facilitate the connection of the evaporator 410 with the pipelines of the compressor and other devices, the evaporator is located near the bottom of the first chamber 110 to reduce the distance from the compressor compartment.

[0091] In some embodiments, in order to save space in the first chamber 110, the fan 600 is located above the evaporator 410, and the fan 600 overlaps with the orthographic projection of the evaporator 410 toward the ground. It should be noted that the orthographic projection of the fan 600 and the evaporator 410 toward the ground can partially overlap or completely overlap. In this way, compared with the fan 600 and the evaporator 410 being arranged front and back along the depth direction of the box 100, the size of the first chamber 110 along the depth direction of the box 100 can be reduced, thereby increasing the size of the second chamber 120.

[0092] In some embodiments, the air conditioning device may include a heating element, which is disposed in the first chamber 110 to heat the air in the first chamber 110 , and the heated air flows into the second chamber 120 under the action of the fan 600 .

[0093] It is understandable that the heating element can also accelerate the evaporation of water, thereby being used to increase the humidity of the air in the second chamber 120 .

[0094] Exemplarily, the heating element may be a heating wire or a heating plate.

[0095] In some embodiments, the heating element is disposed near the evaporator 410, or the heating element is in contact with the evaporator 410. In this way, the frost generated during the refrigeration process of the evaporator 410 can be defrosted by the heating element. A drain pipe 500 can be disposed at the bottom of the first chamber 110 to discharge the defrosted water into the evaporation dish in the press chamber.

[0096] In some embodiments, the air conditioning device further includes a carbon dioxide generator, which is located in the first chamber 110 and is used to generate carbon dioxide to meet the growth requirements of fruits and vegetables.

[0097] In some embodiments, the first air return port 1621 and the first air outlet 1622 are arranged at intervals along the length direction of the box, and the first air return port 1621 is located above the first air outlet 1622. Since heat is generated during the growth of fruits and vegetables, and heat is generated when the lighting assembly is working, the hot air in the second chamber 120 moves upward, so that under the action of the fan and the rising of the hot air, the air circulation efficiency is high, which is conducive to energy saving.

[0098] In some embodiments, the number of the first air outlets 1622 is at least two, the first return air outlet 1621 and the at least two first air outlets 1622 are arranged at intervals along the length direction of the cabinet 100, and the first return air outlet 1621 is located on one side of the at least two first air outlets 1622 along the length direction of the cabinet. For example, the first return air outlet 1621 is located above the at least two first air outlets 1622 along the length direction of the cabinet 100. Alternatively, the first return air outlet 1621 is located below the at least two first air outlets 1622 along the length direction of the cabinet 100.

[0099] Under the action of the fan 600 in the housing 100 , the air in the second chamber 120 returns to the second chamber 120 via the first return air port 1621 , the first chamber 110 and the first air outlet 1622 in sequence.

[0100] It can be understood that since the distances from different first air outlets 1622 to the first return air outlet 1621 are different, when the air outlets of each first air outlet 1622 are the same, the first air outlet 1622 that is close to the first return air outlet 1621 has a shorter return air path and a faster return air speed, while the first air outlet 1622 that is far from the first return air outlet 1621 has a longer return air path and a smaller air volume, and it is not easy to return the air from far away to the first return air outlet 1621, resulting in poor air uniformity in the second chamber 120.

[0101] Therefore, in this embodiment, in order to improve the uniformity of the air in the second chamber 120 , the air volume of the first air outlet 1622 gradually decreases from a direction away from the first return air outlet 1621 to a direction close to the first return air outlet 1621 .

[0102] In some embodiments, of two adjacent first air outlets 1622, the air volume of the one away from the first return air outlet 1621 is 1.1-3 times that of the other. It is understandable that when the air volume of the one away from the first return air outlet 1621 is less than 1.1 times that of the other, the first air outlet 1622 away from the first return air outlet 1621 is prone to poor return air flow. When the air volume of the one away from the first return air outlet 1621 is greater than 3 times that of the other, under the premise of ensuring smooth return air flow at the nearest first air outlet 1622, the required overall air volume is relatively large, which is not conducive to energy saving and cost reduction.

[0103] Exemplarily, of the two adjacent first air outlets 1622, the air volume of the one away from the first return air outlet 1621 is 1.2-2 times that of the other. Alternatively, of the two adjacent first air outlets 1622, the air volume of the one away from the first return air outlet 1621 is 1.1-2.5 times that of the other. Alternatively, of the two adjacent first air outlets 1622, the air volume of the one away from the first return air outlet 1621 is not more than 3 times the air volume of the other. Alternatively, of the two adjacent first air outlets 1622, the air volume of the one away from the first return air outlet 1621 is not less than 1.1 times the air volume of the other.

[0104] Exemplarily, when the number of the first air outlets 1622 is three, the ratio of the air volumes of the first air outlets 1622 from the direction away from the first return air outlet 1621 to the direction close to the first return air outlet 1621 is 5:3:2.

[0105] In a possible implementation, the opening size of the first air outlet 1622 gradually decreases from a direction away from the first return air outlet 1621 to a direction close to the first return air outlet 1621 .

[0106] Figure 5 This is a structural schematic diagram of the air distribution structure in the fruit and vegetable cultivation equipment provided in the embodiment of the present application. Figure 6 This is a cross-sectional view of the air distribution structure in the fruit and vegetable cultivation equipment provided in an embodiment of the present application.

[0107] See also Figures 4 to 6 As shown, in another possible implementation, it also includes an air distribution structure 900, which is located in the first chamber 110. The air distribution structure 900 is configured to change the air outlet volume of the first air outlet 1622 so that the air outlet volume of the first air outlet 1622 gradually decreases from the direction away from the first return air outlet 1621 to the direction close to the first return air outlet 1621.

[0108] It is understandable that during the growth of fruits and vegetables, the first air outlet 1622 is easily blocked, thereby affecting the opening size of the first air outlet 1622. In the present application, the air distribution structure 900 is used to change the air output of the first air outlet 1622. The air distribution structure 900 is located in the first chamber 110, and the air output is not easily affected by fruits and vegetables.

[0109] In some embodiments, the air distribution structure 900 includes a wind shield 910 and a ventilation part 920. Part of the air entering the first chamber 110 through the first return air port 1621 is guided by the wind shield 910 and flows to the second chamber 120 through the opposite first air outlet 1622, and part of the air flows toward the adjacent first air outlet 1622 through the ventilation part 920. In this way, the air distribution structure 900 has a simpler structure, lower cost, and occupies less space.

[0110] It is understandable that the number of the air splitting structures 900 may be equal to the number of the first air outlets 1622, and the air splitting structures 900 are arranged in a one-to-one correspondence with the first air outlets 1622. Alternatively, the number of the air splitting structures 900 may be one less than the number of the first air outlets 1622, and the first air outlet 1622 closest to the first return air outlet 1621 is not provided with an air splitting structure 900.

[0111] In some embodiments, in order to improve the smoothness of air flow, the wind shielding portion 910 includes a connecting segment 911, an arc segment 912, and an extending segment 913 which are connected in sequence.

[0112] The connecting section 911 is connected to the inner wall of the first chamber 110 facing the second chamber 120, and the connecting section 911 is located on the side of the first air outlet 1622 away from the first return air outlet 1621. The side of the arc section 912 away from the first return air outlet 1621 is connected to the connecting section 911, and the extension section 913 is connected to the side of the arc section 912 away from the connecting section 911. The extension section 913 is spaced from the inner wall of the first chamber 110 facing the second chamber 120, and the extension section 913 is opposite to the first air outlet 1622 and extends to the side of the first air outlet 1622 facing the first return air outlet 1621.

[0113] The air flows toward the arc segment 912 through the gap between the extension segment 913 and the inner wall of the first chamber 110 facing the second chamber 120 , and moves to the second chamber 120 through the first air outlet 1622 opposite to the extension segment 913 under the guiding effect of the arc segment 912 .

[0114] In some embodiments, the ventilation portion 920 is located on a side of the wind shielding portion 910 away from the first air outlet 1622. The ventilation portion 920 includes a ventilation opening, and the extension section 913 and the inner wall of the first chamber 110 form the ventilation opening. In this way, the occupied space is small.

[0115] It is understandable that, along a cross section perpendicular to the length direction of the box body 100 , the ratio of the opening size of the vent to the opening size of the air duct of the first chamber 110 affects the air output of the first air outlet 1622 corresponding to the air distribution structure 900 .

[0116] In some embodiments, along the length direction of the box body 100 , the opening size of the air duct of the first chamber 110 gradually decreases along the air flow direction.

[0117] Figure 7 This is a schematic diagram of the structure of the second type of box in the fruit and vegetable cultivation equipment provided in an embodiment of the present application.

[0118] In some embodiments, the first chamber 110 and the second chamber 120 are arranged side by side along the depth direction of the box 100, or the first chamber 110 and the second chamber 120 are arranged side by side along the width direction of the box 100. The following description is made by taking the first chamber 110 and the second chamber 120 arranged side by side along the depth direction of the box 100 as an example. In order to make the size of the second chamber 120 larger, the size of the first chamber 110 along the depth direction of the box 100 is smaller. For example, the size of the first chamber 110 along the depth direction of the box 100 is 10 to 30 cm.

[0119] Therefore, when the evaporator 410 or the heating element is working, the cooling capacity of the evaporator 410 or the heat of the heating element is easily transferred directly to the second chamber 120 through the cabinet 100, causing local overcooling or overheating in the second chamber 120.

[0120] In order to solve the above technical problems, in some embodiments, the box 100 is configured with a first chamber 110, a second chamber 120 and a third chamber 163. The third chamber 163 is located between the first chamber 110 and the second chamber 120, and the third chamber 163 includes a return air area 1631 and an outlet air area 1632 separated from each other. In other words, the return air area 1631 and the outlet air area 1632 are not connected.

[0121] The housing 100 is configured with a first return air port 1621 and at least two first air outlets 1622 spaced apart from each other. The first return air port 1621 communicates with the second chamber 120 and the return air area 1631 , and the first air outlet 1622 communicates with the second chamber 120 and the air outlet area 1632 .

[0122] The housing 100 is configured with a second return air port 1611 and a second air outlet 1612 . The second return air port 1611 is connected to the first chamber 110 and the return air area 1631 , and the second air outlet 1612 is connected to the first chamber 110 and the air outlet area 1632 .

[0123] The fan 600 is located in the housing 100. For example, the fan 600 may be located in the first chamber 110 or the return air zone 1631 or the outlet air zone 1632, etc. Under the action of the fan 600, the air in the second chamber 120 flows back to the second chamber 120 through the first return air port 1621, the return air zone 1631, the second return air port 1611, the first chamber 110, the second outlet air port 1612, the outlet air zone 1632 and the first outlet air port 1622 in sequence.

[0124] The hydroponic assembly 200 is disposed in the second chamber 120 at intervals. The temperature regulating device is disposed in the first chamber 110.

[0125] It is understandable that by providing the third chamber 163, the uniformity of the distribution of the first air outlets 1622 can be improved. The following is an example in which the first return air outlet 1621 is located above at least two first air outlets 1622 along the length direction of the box body 100. When the third chamber 163 is provided, the air of the second chamber 120 enters the first chamber 110 through the first return air outlet 1621, the return air area 1631, and the second return air outlet 1611, moves downward along the first chamber 110, and then enters the air outlet area 1632 through the second air outlet 1612, and then moves upward along the air outlet area 1632, and enters the second chamber 120 through the first air outlet 1622. When the third chamber 163 is not provided, the air in the second chamber 120 enters the first chamber 110 through the first return air port 1621, moves downward along the first chamber 110, moves to the position of the first air outlet 1622, and enters the second chamber 120 through the first air outlet 1622. In other words, the first air outlet 1622 can only be provided at the lower part of the first chamber 110, and the air conditioning device is provided at the upper part of the first chamber 110. Therefore, by providing the third chamber 163, the uniformity of the distribution of the first air outlet 1622 can be improved, and when the size of the second chamber 120 along the length direction of the box body is constant, the number of the first air outlet 1622 can be increased.

[0126] Understandably, see Figure 7As shown, in some embodiments, the housing 100 is constructed with at least two first air outlets 1622 arranged at intervals. At least two hydroponic components 200 are arranged in the second chamber 120, and at least two first air outlets 1622 are arranged in a one-to-one correspondence with at least two hydroponic components 200. The varieties of fruits and vegetables cultivated in each hydroponic component 200 are different, or the fruits and vegetables of the same variety in different growth periods are cultivated in each hydroponic component. That is to say, in some cases, the fruits and vegetables in each hydroponic component 200 have different requirements for heat, humidity or carbon dioxide. Therefore, a wind distribution structure 900 can be set in the air outlet area 1632, and the wind distribution structure 900 is configured to change the air outlet volume of the first air outlet 1622. In this way, the wind distribution structure 900 is arranged in the air outlet area 1632, which can effectively avoid affecting the air outlet volume of the first air outlet 1622 due to the obstruction of fruits and vegetables, and affecting the accuracy of air outlet volume control.

[0127] In some embodiments, the wind splitting structure 900 includes a wind shielding portion 910 and a ventilation portion 920. Part of the air entering the wind outlet area 1632 through the second air outlet 1612 is guided by the wind shielding portion 910 and flows to the second chamber 120 through the opposite first air outlet 1622, and part of the air flows toward the adjacent first air outlet 1622 through the ventilation portion 920. In this way, the wind splitting structure 900 has a simpler structure and occupies a smaller space, which is conducive to reducing the occupied space of the third chamber 163.

[0128] In some embodiments, see Figure 5 and Figure 6 As shown, in order to make the air flow smooth, the wind shield 910 includes a connecting section 911, an arc section 912 and an extension section 913 connected in sequence. The connecting section 911 is connected to the inner wall of the third chamber 163 facing the second chamber 120, and the connecting section 911 is located on the side of the first air outlet 1622 away from the second air outlet 1612. The side of the arc section 912 away from the second air outlet 1612 is connected to the connecting section 911, and the extension section 913 is connected to the side of the arc section 912 away from the connecting section 911. The extension section 913 is spaced from the inner wall of the third chamber 163 facing the second chamber 120, and the extension section 913 is opposite to the first air outlet 1622 and extends to the side of the first air outlet 1622 facing the second air outlet 1612.

[0129] In some embodiments, the ventilation portion 920 is located on a side of the wind shielding portion 910 away from the first air outlet 1622. The ventilation portion 920 includes a vent, and the extension section 913 and the inner wall of the third chamber 163 form the vent. In this way, the structure is simpler and occupies less space.

[0130] It is understandable that, along a cross section perpendicular to the length direction of the box body 100 , the ratio of the opening size of the vent to the opening size of the air duct in the air outlet area 1632 affects the air volume of the first air outlet 1622 corresponding to the air distribution structure 900 .

[0131] In some embodiments, along the length direction of the box body 100, the opening size of the air duct of the air outlet area 1632 gradually decreases along the air flow direction.

[0132] In some embodiments, in order to adjust the air volume of the first air outlet 1622 as needed, the ventilation part 920 further includes a moving member, which is movably connected to the wind shield 910, and the moving member moves relative to the wind shield 910 to cover at least part of the vent or open the vent. Exemplarily, the moving member can be rotatably connected to the wind shield 910, or slidably connected.

[0133] In some embodiments, in order to improve the conditioning efficiency and conditioning effect of the air in the second chamber 120, the fan 600 is located in the first chamber 110 and opposite to the second return air outlet 1611, the air conditioning device is located below the fan 600, and the second air outlet 1612 is located below the air conditioning device.

[0134] In some embodiments, an arc-shaped guide portion 1613 is provided at the bottom of the second air outlet 1612, and the arc-shaped guide portion 1613 is used to guide the air to flow obliquely upward to enter the air outlet area 1632. The vertical projection length of the arc-shaped guide portion 1613 is not less than the vertical projection length of the second air outlet 1612. In this way, the direction of the airflow can be efficiently guided to improve the air supply efficiency.

[0135] In some embodiments, in order to effectively prevent the first air outlet 1622 from blowing directly to the roots of fruits and vegetables and affecting their growth, at least two first air outlets 1622 are arranged in one-to-one correspondence with at least two hydroponic assemblies 200, and at least two first air outlets 1622 are respectively located above the corresponding hydroponic assemblies 200, and the spacing between the first air outlets 1622 and the corresponding hydroponic assemblies 200 is greater than one-third of the spacing between two adjacent hydroponic assemblies 200. Exemplarily, it is greater than half of the spacing between two adjacent hydroponic assemblies 200.

[0136] In some embodiments, at least three hydroponic assemblies 200 are spaced apart along the length direction of the housing 100. The first air return port 1621 and at least two first air outlets 1622 are spaced apart along the length direction of the housing, and the first air return port 1621 is located on one side of the at least two first air outlets 1622 along the length direction of the housing 100.

[0137] The number of hydroponic components 200 is consistent with the sum of the number of first air return ports 1621 and first air outlets 1622. The first air return ports 1621 and at least two first air outlets 1622 are arranged in one-to-one correspondence with at least three hydroponic components 200. The first air return ports 1621 and at least two first air outlets 1622 are respectively located above the corresponding hydroponic components 200, and the spacing between the first air return ports 1621 and the at least two first air outlets 1622 and the corresponding hydroponic components 200 is greater than one-third of the spacing between two adjacent hydroponic components 200. For example, it may be greater than half of the spacing between two adjacent hydroponic components 200.

[0138] In some embodiments, the box body 100 includes: an outer shell, a box liner, and an air duct assembly 160. The box liner is located inside the outer shell. The air duct assembly 160 is located inside the box liner.

[0140] See also Figures 8 to 12 As shown, the air duct assembly 160 includes a first partition 161 and a second partition 162, which are sequentially arranged along the depth direction of the box body 100, and the space between the first partition 161 and the inner bottom wall of the box liner is the first chamber 110. The space between the second partition 162 and the first partition 161 is the third chamber 163, and the space on the side of the second partition 162 away from the first partition 161 is the second chamber 120.

[0141] In other embodiments, the air duct assembly 160 includes a first partition 161, a second partition 162, and a third partition. The third partition is close to the inner bottom wall of the box along the depth direction of the box body 100, and the third partition, the first partition 161, and the second partition 162 are arranged in sequence along the depth direction. The space between the first partition 161 and the third partition is the first chamber 110. The space between the second partition 162 and the first partition 161 is the third chamber 163, and the space on the side of the second partition 162 away from the first partition 161 is the second chamber 120.

[0142] The second partition 162 is provided with a first return air port 1621 and at least two first air outlets 1622 spaced apart from each other. The first partition 161 is provided with a second return air port 1611 and a second air outlet 1612 .
