Description

[0001] This application claims the priority of a Chinese patent application titled "Fruit and Vegetable Cultivation Equipment" with the application number 202311864260.9 and filed with the Chinese Patent Office on December 29, 2023. The entire content thereof is incorporated herein by reference. Technical Field

[0002] The embodiments of the present application relate to the technical field of household appliances, and particularly to a fruit and vegetable cultivation equipment. Background Art

[0003] With the improvement of people's living conditions, people pay more and more attention to the quality of life and their own health. Among them, the problem of pesticide residues in fruits and vegetables is a focus that the common people are very concerned about every day. In addition, with the fast-paced operation of work and life in busy metropolises, some fruits and vegetables are difficult to store, which brings difficulties for office workers' families to eat fresh fruits and vegetables. Therefore, having a home garden can improve this situation. One can eat fresh fruits and vegetables all year round without going out, which is cost-saving, convenient, green and pollution-free. It looks green and refreshing, and one can also enjoy the fun of self-planting and self-harvesting, killing multiple birds with one stone.

[0004] In the related art, the fruit and vegetable cultivation equipment includes a box body and a hydroponic component. The box body includes a first chamber and a second chamber that communicate with each other. The hydroponic component is arranged in the second chamber, and the number of the hydroponic components is at least two, and at least two hydroponic components are arranged at intervals. In order to supplement carbon dioxide in the box body, an air inlet and an air outlet are arranged at the bottom of the box body. The air outside the box body sequentially flows through the air inlet, the first chamber, and the air outlet into the second chamber, and the air in the second chamber sequentially flows through the air return port, the first chamber, and the air outlet to the outside. Among them, the number of the air outlets is at least two, and at least two air outlets are arranged at intervals, and the sizes of the air outlets are different to change the air output of each air outlet, so as to meet the growth needs of fruits and vegetables. For example, the varieties of fruits and vegetables cultivated in each hydroponic component are different, or the fruits and vegetables in each hydroponic component are of the same variety but in different growth periods. Therefore, in some cases, the demands for carbon dioxide of the fruits and vegetables in each hydroponic component are different.

[0005] However, during the growth process of fruits and vegetables, the air outlets will be blocked, affecting the accuracy of air output regulation. Summary of the Invention

[0078] [Overall Structure]

[0079] Figure 1 is a schematic structural diagram of the fruit and vegetable cultivation equipment provided by the embodiment of the present application. Figure 2 is a schematic structural diagram of the fruit and vegetable cultivation equipment provided by the embodiment of the present application after removing the door body. Figure 3 is a schematic structural diagram of the fruit and vegetable cultivation equipment provided by the embodiment of the present application after removing the door body and the outer shell.

[0080] See Figures 1 to 3 As shown, the fruit and vegetable cultivation equipment provided by the embodiment of the present application can form an appearance by a box body 100 and a door body 300. 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.

[0081] In this embodiment, a hydroponic component 200 is arranged in the box body 100. Among them, 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 box body 100, so as to improve the space utilization rate of the box body 100. Exemplarily, the number of the hydroponic components 200 can be multiple, and multiple hydroponic components 200 are arranged at intervals along the length direction of the box body 100. For example, the number of the hydroponic components 200 is four. Among them, the length direction of the box body 100 is the direction shown by the Z axis.

[0082] The hydroponic component 200 is configured to hold nutrient solution and fruit and vegetable seedlings. Exemplarily, the hydroponic component 200 can cultivate leafy vegetables such as lettuce and edible gynura, and some fruits such as strawberries, melons, and tomatoes.

[0083] In some embodiments, for the convenience of observing and operating fruits and vegetables, the hydroponic component 200 is slidably connected to the box body 100, so that the hydroponic component 200 can be moved to the outside of the box body 100, facilitating user operation.

[0084] In some embodiments, the fruit and vegetable cultivation device includes a liquid supply system 700, which can be used to circulate and supply nutrient solution to the hydroponic component 200. That is to say, 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 then returns to the liquid supply system 700.

[0085] 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 component 800, which is arranged above the hydroponic component 200. Exemplarily, the amount of light irradiated by the lighting component 800 can be set to be similar to sunlight, and the amount of light and irradiation time most suitable for the cultivated fruits and vegetables can be set.

[0086] In some embodiments, when the number of hydroponic components 200 is at least two, at least two hydroponic components 200 can be arranged at intervals along the length direction of the box body 100, and at least two lighting components 800 are arranged in one-to-one correspondence with at least two hydroponic components 200.

[0087] In some embodiments, the lighting component 800 can be arranged at the bottom of the hydroponic component 200 above the corresponding hydroponic component 200, so that there is no need to additionally set an installation structure for the lighting component 800 in the box body 100, saving space and improving the utilization rate of space.

[0088] In some embodiments, the fruit and vegetable cultivation device includes an air conditioning device, which can include at least one of a temperature adjustment device, a humidity adjustment device, and a carbon dioxide adjustment device, so as to adjust the air condition in the box body to meet the growth requirements of fruits and vegetables. For example, the temperature adjustment device includes a refrigeration system 400 and a heating element. The carbon dioxide adjustment device can include a carbon dioxide generator.

[0089] In some embodiments, a display component is arranged outside the box body 100, and the display component can intuitively display the state of the fruit and vegetable cultivation device. In addition, for the convenience of users to set parameters, the fruit and vegetable cultivation device further includes a control panel, which is electrically connected to the controller. The control panel is a touch panel and can be set on the door body 300 or can be set on the top of the box body 100.

[0090] In some embodiments, the fruit and vegetable cultivation device includes a fan, which is arranged in the box body 100, and the fan drives the air to flow, thereby realizing the circulation of the air in the box body 100.

[0091] In some embodiments, the fruit and vegetable cultivation device includes a blower, which is disposed inside the box body 100. The blower drives the air flow, thereby realizing the circulation of the air between the box body 100 and the external air.

[0114] In some embodiments, to effectively prevent foreign objects from entering the interior of the box body 100 through the air outlet duct, the air outlet structure 1200 further includes a plurality of second partition plates 1230. The second partition plates 1230 are arranged at intervals in the air outlet duct, and the extending direction of the second partition plates 1230 is the same as the extending direction of the air outlet duct.

[0115] In some embodiments, the second partition plates 1230 can be rotatably connected to the air outlet structure body 1210 to adjust the air outlet angle.

[0116] Figure 11 It is a schematic structural diagram of the air duct assembly in the fruit and vegetable cultivation device provided by the embodiment of the present application.

[0117] See Figure 5 , Figure 6 and Figure 11 As shown, in some embodiments, the box body 100 includes a housing 130, a box liner 150, and an air duct assembly 160.

[0118] The housing 130 has a first opening and a second opening that are spaced apart. The inner container 150 is located within the housing 130. The inner container 150 has a first avoidance opening and a second avoidance opening. The first avoidance opening is opposite to the first opening, and the second avoidance opening is opposite to the second opening.

[0119] The air duct assembly 160 is located within the inner container 150. A first chamber 110 is configured within the air duct assembly 160. A part of the outer wall of the air duct assembly 160 and a part of the inner wall of the inner container 150 form a second chamber 120.

[0120] The air duct assembly 160 has a first connection structure 164 and a second connection structure 165 that are spaced apart. The first connection structure 164 is inserted into the first opening through the first avoidance opening. An air inlet 170 is provided on the side of the first connection structure 164 facing away from the second chamber. The first connection portion 1020 is inserted into the first connection structure 164. The second connection structure 165 is inserted into the second opening through the second avoidance opening. An air outlet 180 is provided on the side of the second connection structure 165 facing away from the second chamber. The second connection portion 1220 is inserted into the second connection structure 165. In this way, the reliability of the connection between the air inlet structure 1000 and the air outlet structure 1200 and the box body 100 is relatively high, and the installation efficiency is relatively high.

[0121] Figure 12 It is a schematic structural view of the inner container in the fruit and vegetable cultivation device provided by the embodiment of the present application.

[0122] See Figure 12 As shown, in some embodiments, in order to effectively prevent the foaming material from overflowing to the outside of the box body 100 through the first avoidance opening and the first opening, the inner container 150 is provided with a first blocking portion 151. The first blocking portion 151 includes a first blocking section and a second blocking section that are in communication with each other. The first blocking section is connected to the side of the inner container 150 facing the first rear panel, and the first blocking section is in communication with the first avoidance opening. The inner cavity opening size of the first blocking section is not greater than the opening size of the first avoidance opening. The second blocking section is connected to the side of the first blocking section facing away from the inner container 150 and abuts against the first rear panel. The inner cavity opening size of the second blocking section is smaller than the opening size of the first opening. It should be noted that the inner cavity opening sizes of the first blocking section and the second blocking section are not less than the outer wall size of the first connection structure 164, so that the first connection structure 164 can be smoothly inserted into the first opening.

[0123] In some embodiments, in order to effectively prevent the foaming material from overflowing to the outside of the box body 100 through the second avoidance port and the second opening, the box 150 is provided with a second blocking portion 152, and the second blocking portion 152 includes a third blocking section and a fourth blocking section that are interconnected, the third blocking section is connected to the side of the box 150 facing the first back plate, and the third blocking section is connected to the second avoidance port, and the inner cavity opening size of the third blocking section is not larger than the opening size of the second avoidance port. The fourth blocking section is connected to the side of the third blocking section away from the box 150, and abuts against the first back plate, and the inner cavity opening size of the fourth blocking section is smaller than the opening size of the first opening. It should be noted that the inner cavity opening size of the third blocking section and the inner cavity opening size of the fourth blocking section are not smaller than the outer wall size of the second connecting structure 165, so that the second connecting structure 165 can be smoothly inserted into the second opening.

[0124] In some embodiments, to reduce the impact on the appearance, the first chamber 110 and the second chamber 120 are arranged side by side along the depth direction of the box 100, and the air inlet 170 and the air outlet 180 are located at the back of the box. The depth direction is the direction shown by the Y axis.

[0125] See also Figure 5 As shown, in some embodiments, since heat is generated during the growth of fruits and vegetables, and heat is generated when the illumination assembly 800 is working, the hot air in the second chamber 120 moves upward, and under the action of the fan 600 and the rising of the hot air, the air circulation efficiency is high, which is conducive to energy saving. Therefore, the first area 111 is located above the second area 112. The external air flows into the second chamber 120 through the air inlet 170 and the second area 112 in sequence, and the air in the second chamber 120 flows upward, and flows to the outside through the first area 111 and the exhaust port 180 in sequence.

[0126] In some embodiments, the housing 100 is configured with a first air outlet 1622 and a first air return outlet 1621. The first air outlet 1622 is in communication with both the second area 112 and the second chamber 120, and the first air return outlet 1621 is in communication with both the second chamber 120 and the first area 111. The air inlet 170 is located above the first air outlet 1622, the first air return outlet 1621 is located above the first air outlet 1622, and the air outlet 180 is located above the first air return outlet 1621.

[0127] External air enters the second region 112 through the air inlet 170, moves downward along the second region 112 to the position of the first air outlet 1622, and flows into the second chamber 120 through the first air outlet 1622. The air in the second chamber 120 flows upward and enters the first region 111 through the first air return opening 1621, moves upward along the first region 111 to the position of the air exhaust opening 180, and flows to the outside through the air exhaust opening. In this way, under the action of the fan and the rising hot air, the circulation effect is better, the air circulation efficiency is higher, which is beneficial to energy conservation.

[0128] In some embodiments, in order to improve the air circulation efficiency, the fan 600 is located in the first region 111 and the fan 600 is opposite to the first air return opening 1621.

[0129] In some embodiments, it further includes a temperature adjustment device, and the temperature adjustment device is arranged in the second region 112.

[0130] Specifically, the temperature adjustment device includes a refrigeration system and a heating element. The refrigeration system includes an evaporator 410. The evaporator 410 and the heating element are arranged in the second region 112, so as to adjust the temperature of the externally entering air, which is beneficial to maintaining the stability of the air in the second chamber 120.

[0131] In some embodiments, the air inlet 170 is located above the temperature adjustment device, and the first air outlet 1622 is located below the temperature adjustment device. In this way, it is beneficial for the externally entering air to fully contact the temperature adjustment device, thereby improving the temperature adjustment effect.

[0132] It can be understood 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.

[0133] In some embodiments, the box body 100 includes a compressor compartment 140, and the compressor 420 and the condenser of the refrigeration system are located in the compressor compartment. The compressor compartment 140 is located at the bottom of the box body 100. Therefore, in order to facilitate the pipeline connection between the evaporator 410 and devices such as the compressor 420, the evaporator 410 is located in the second region 112 to shorten the distance from the compressor compartment 140.

[0134] In some embodiments, to save the space of the first chamber 110, the blower 600 is located in the first region 111, and the orthographic projection of the blower 600 and the evaporator 410 onto the ground coincides. It should be noted that the orthographic projection of the blower 600 and the evaporator 410 onto the ground may partially coincide or completely coincide. In this way, compared with the front-to-back arrangement of the blower 600 and the evaporator 410 along the depth direction of the cabinet 100, the size of the first chamber 110 along the depth direction of the cabinet 100 can be reduced, so that the size of the second chamber 120 can be increased.

[0135] It can be understood that the heating element can also accelerate the evaporation of moisture, so as to increase the humidity of the air in the second chamber 120. Exemplarily, the heating element can be a heating wire or a heating sheet.

[0136] In some embodiments, the heating element is arranged at a position close to the evaporator 410, or the heating element abuts against 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 arranged at the bottom of the first chamber 110, so as to drain the defrosting water into the evaporating dish in the compressor compartment.

[0137] In some embodiments, the first chamber 110 and the second chamber 120 are arranged side by side along the depth direction of the cabinet 100, or the first chamber 110 and the second chamber 120 are arranged side by side along the width direction of the cabinet 100. Hereinafter, taking the example that the first chamber 110 and the second chamber 120 are arranged side by side along the depth direction of the cabinet 100, 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 cabinet 100 is smaller. For example, the size of the first chamber 110 along the depth direction of the cabinet 100 is 10 to 30 cm.

[0138] Therefore, when the evaporator 410 or the heating element works, the cold quantity of the evaporator 410 or the heat quantity of the heating element is easily directly transferred into the second chamber 120 through the cabinet, resulting in local overcooling or overheating in the second chamber 120.

[0139] Figure 13 This is a schematic structural diagram of the second cabinet in the fruit and vegetable cultivation equipment provided by the embodiments of the present application.

[0140] To solve the above technical problems, refer to Figure 17As shown, in some embodiments, the cabinet 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 air outlet area 1632 that are separated from each other. That is to say, the return air area 1631 and the air outlet area 1632 are not connected. Both the return air area 1631 and the air outlet area 1632 are connected to the second chamber 120, and the return air area 1631 is connected to the first area 111, and the air outlet area 1632 is connected to the second area 112. The first chamber 110 includes a first area 111 and a second area 112, and the first area 111 and the second area 112 are not connected. The cabinet 100 is configured with an air inlet 170 and an air outlet 180, the air inlet 170 is connected to the second area 112, and the air outlet 180 is connected to the first area 111.

[0141] Under the action of the fan 600, the external air flows through the air inlet 170, the second area 112, and the air outlet area 1632 in sequence and then flows into the second chamber 120. The air in the second chamber 120 flows through the return air area 1631, the first area 111, and the air outlet 180 in sequence and then flows to the outside.

[0142] In some embodiments, the return air area 1631 is located above the air outlet area 1632. The first area 111 is located above the second area 112.

[0143] Under the action of the fan, the external air flows through the air inlet 170, the second area 112, and the air outlet area 1632 in sequence and then flows into the second chamber 120. The air in the second chamber 120 flows upward and flows through the return air area 1631, the first area 111, and the air outlet 180 in sequence and then flows to the outside.

[0144] In some embodiments, the cabinet 100 is configured with a first air outlet 1622 and a first return air inlet 1621. The first air outlet 1622 is connected to both the air outlet area 1632 and the second chamber 120. The first return air inlet 1621 is connected to both the return air area 1631 and the second chamber 120. The cabinet 100 is configured with a second air outlet 1612 and a second return air inlet 1611. The second air outlet 1612 is connected to both the second area 112 and the air outlet area 1632. The second return air inlet 1611 is connected to both the return air area 1631 and the first area 111. The air inlet 170 is located above the second air outlet 1612, the first air outlet 1622 is located above the second air outlet 1612, the first return air inlet 1621 is located above the first air outlet 1622, the second return air inlet 1611 is located below the first return air inlet 1621, and the air outlet 180 is located above the second return air inlet 1611.

[0145] External air enters the second region 112 through the air inlet 170, moves downward along the second region 112 to the position of the second air outlet 1612, enters the air outlet area 1632 through the second air outlet 1612, and moves upward along the air outlet area 1632 to the position of the first air outlet 1622, and flows into the second chamber 120 through the first air outlet 1622. The air in the second chamber 120 flows upward and enters the air return area 1631 through the first air return opening 1621, moves downward along the air return area 1631 to the position of the second air return opening 1611, and flows into the first region 111 through the second air return opening 1611, moves upward along the first region 111 to the position of the air discharge opening 180, and flows to the outside through the air discharge opening 180. In this way, under the action of the fan 600 and the rising hot air, the efficiency of air circulation is relatively high, which is beneficial to energy conservation.

[0146] In some embodiments, the number of the first air outlets 1622 is at least two. The first air return opening 1621 and at least two first air outlets 1622 are arranged at intervals along the length direction of the box body 100, and the first air return opening 1621 is located on one side of at least two first air outlets 1622 along the length direction of the box body 100. For example, the first air return opening 1621 is located above at least two first air outlets 1622 along the length direction of the box body 100. Or, the first air return opening 1621 is located below at least two first air outlets 1622 along the length direction of the box body 100.

[0147] Under the action of the fan 600 in the box body 100, the air in the second chamber 120 flows to the outside of the box body 100 through the first air return opening 1621, the air return area 1631, the first region 111 and the air discharge opening 180 in sequence.

[0148] It can be understood that since the distances from different first air outlets 1622 to the first air return opening 1621 are different, when the air discharge amounts of each first air outlet 1622 are the same, for the first air outlet 1622 close to the first air return opening 1621, the air return path is shorter and the air return speed is faster, while for the first air outlet 1622 far from the first air return opening 1621, the air return path is longer. When the air volume is small, it is not easy to return the air in the distance to the first air return opening 1621, resulting in poor air uniformity in the second chamber 120.

[0149] Therefore, as shown in Figure 4 In this embodiment, in order to improve the air uniformity in the second chamber 120. From the direction far from the first air return opening 1621 to the direction close to the first air return opening 1621, the air discharge amount of the first air outlet 1622 gradually decreases.

[0150] In some embodiments, among two adjacent first air outlets 1622, the air volume of the one farther from the first air return opening 1621 is 1.1 - 3 times that of the other. It can be understood that when the air volume of the one farther from the first air return opening 1621 is less than 1.1 times that of the other, it is easy for the air return of the first air outlet 1622 farther from the first air return opening 1621 to be blocked. When the air volume of the one farther from the first air return opening 1621 is more than 3 times that of the other, under the premise of ensuring smooth air return of the nearest first air outlet 1622, the required total air volume is relatively large, which is not conducive to energy conservation and cost reduction.

[0151] Exemplarily, among two adjacent first air outlets 1622, the air volume of the one farther from the first air return opening 1621 is 1.2 - 2 times that of the other. Or, among two adjacent first air outlets 1622, the air volume of the one farther from the first air return opening 1621 is 1.1 - 2.5 times that of the other. Or, among two adjacent first air outlets 1622, the air volume of the one farther from the first air return opening 1621 is not more than 3 times that of the other. Or, among two adjacent first air outlets 1622, the air volume of the one farther from the first air return opening 1621 is not less than 1.1 times that of the other.

[0152] Exemplarily, when the number of the first air outlets 1622 is three, in the direction from the one farther from the first air return opening 1621 to the one closer to the first air return opening 1621, the ratio of the air volumes of the first air outlets 1622 is 5:3:2.

[0153] In a possible implementation manner, in the direction from the one farther from the first air return opening 1621 to the one closer to the first air return opening 1621, the opening size of the first air outlet 1622 gradually decreases.

[0154] In another possible implementation manner, it further includes an air distribution structure 900. The air distribution structure 900 is located in the second region 112 and is configured to change the air volume of the first air outlet 1622, so that in the direction from the one farther from the first air return opening 1621 to the one closer to the first air return opening 1621, the air volume of the first air outlet 1622 gradually decreases.

[0155] It can be understood that during the growth process of fruits and vegetables, it is easy to block the first air outlet 1622, thereby affecting the opening size of the first air outlet 1622. In this application, the air distribution structure 900 is used to change the air volume of the first air outlet 1622. The air distribution structure 900 is located in the first chamber 110, and the air volume is not easily affected by fruits and vegetables.

[0156] In some embodiments, refer to Figure 5 and Figure 6As shown, the air distribution structure 900 includes a wind shield 910 and a ventilation part 920. Part of the air entering the second area 112 through the air inlet 170 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.

[0157] 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.

[0158] 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.

[0159] The connecting section 911 is connected to the inner wall of the second area 112 on the side facing the second chamber 120 , and the connecting section 911 is located on the side of the first air outlet 1622 away from the air inlet 170 .

[0160] Among them, the side of the arc segment 912 facing away from the air inlet 170 is connected to the connecting segment 911, the extension segment 913 is connected to the side of the arc segment 912 facing away from the connecting segment 911, the extension segment 913 is spaced apart from the inner wall of the second area 112 facing the second chamber 120, the extension segment 913 is opposite to the first air outlet 1622, and extends to the side of the first air outlet 1622 facing the air inlet 170.

[0161] The air flows toward the arc segment 912 through the gap between the extension segment 913 and the inner wall of the air outlet area 1632 toward 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 .

[0162] 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, and the ventilation portion 920 includes a vent, and the extension section 913 and the inner wall of the second area 112 form the vent. In this way, the structure is simpler and occupies less space.

[0163] 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 .

[0164] In some embodiments, along the length direction of the box body 100, the opening size of the air duct in the air outlet area 1632 gradually decreases in the air flow direction.

[0165] In some embodiments, as shown Figure 13 in the figure, the box body 100 is configured with a first chamber 110, a second chamber 120, and a third chamber 163. The first chamber 110 includes a first area 111 and a second area 112, and the first area 111 is not communicated with the second area 112. The third chamber 163 includes a return air area 1631 and an air outlet area 1632, and the return air area 1631 is not communicated with the air outlet area 1632.

[0166] The box body 100 is configured with a first return air inlet 1621 and at least two first air outlets 1622. The first return air inlet 1621 and the at least two first air outlets 1622 are arranged at intervals along the length direction of the box body 100. The first return air inlet 1621 is located on one side of the at least two first air outlets 1622 along the length direction of the box body 100. The first return air inlet 1621 is communicated with the return air area 1631 and is also communicated with the second chamber 120. The first air outlet 1622 is communicated with the air outlet area 1632 and is also communicated with the second chamber 120.

[0167] The box body 100 is configured with a second return air inlet 1611 and a second air outlet 1612. The second return air inlet 1611 is communicated with both the first area 111 and the return air area 1631. The second air outlet 1612 is communicated with both the second area 112 and the air outlet area 1632.

[0168] The box body 100 is configured with an air inlet 170 and an air outlet 180. The air inlet 170 is communicated with both the outside of the box body 100 and the second area 112. The air outlet 180 is communicated with both the outside of the box body 100 and the first area 111.

[0169] The fan 600 is arranged inside the box body 100. The hydroponic component 200 is arranged inside the second chamber 120.

[0170] From the direction far from the first return air inlet 1621 to the direction close to the first return air inlet 1621, the air volume of the first air outlet 1622 gradually decreases.

[0171] It can be understood that by providing the third chamber 163, the uniformity of the distribution of the first air outlets 1622 can be improved. Hereinafter, an example will be described in which the first air return opening 1621 is located above at least two first air outlets 1622 in the length direction of the cabinet 100. When the third chamber 163 is provided, the external air enters the second region 112 through the air inlet 170, moves downward along the second region 112 to the position of the second air outlet 1612, enters the air outlet area 1632 through the second air outlet 1612, and moves upward along the air outlet area 1632 to the position of the first air outlet 1622, and flows into the second chamber 120 through the first air outlet 1622. When the third chamber 163 is not provided, the external air enters the second region 112 through the air inlet 170, moves downward along the second region 112 to the position of the first air outlet 1622, and flows into the second chamber 120 through the first air outlet 1622. That is to say, the first air outlets 1622 can only be provided at the lower part of the second region 112, and a temperature adjustment device is provided at the upper part of the second region 112. Therefore, by providing the third chamber 163, the uniformity of the distribution of the first air outlets 1622 can be improved, and when the size of the second chamber 120 in the length direction of the cabinet 100 is fixed, the number of the first air outlets 1622 that can be provided can be increased.

[0172] In some embodiments, a air distribution structure 900 is further included. The air distribution structure 900 is located in the air outlet area 1632 and is configured to change the air output of the first air outlets 1622 such that the air output of the first air outlets 1622 gradually decreases in the direction from away from the first air return opening 1621 to close to the first air return opening 1621. In this way, by providing the air distribution structure 900 in the air outlet area 1632, it can effectively prevent the air output of the first air outlets 1622 from being affected by the shielding of fruits and vegetables, thus affecting the accuracy of the air output regulation.

[0173] Figure 14 FIG. is a schematic structural view of the air distribution structure in the fruit and vegetable cultivation device provided by the embodiment of the present application. Figure 15 FIG. is a cross-sectional view of the air distribution structure in the fruit and vegetable cultivation device provided by the embodiment of the present application.

[0174] In some embodiments, referring to Figure 14 and Figure 15 as shown, the air distribution structure 900 includes a wind blocking portion 910 and a ventilation portion 920. Part of the air entering the air outlet area 1632 through the second air outlet 1612 is diverted by the wind blocking portion 910 and flows through the opposite first air outlets 1622 into the second chamber 120, and part of the air flows toward the adjacent first air outlets 1622 through the ventilation portion 920. In this way, the structure of the air distribution structure 900 is relatively simple and occupies a small space, which is conducive to reducing the occupied space of the third chamber 163.

[0175] In some embodiments, to ensure smooth air flow, the wind deflector 910 includes a connecting section 911, an arc section 912, and an extension section 913 that are connected in sequence. The connecting section 911 is connected to the inner wall of the air outlet area 1632 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. There is a gap between the extension section 913 and the inner wall of the air outlet area 1632 facing the second chamber 120. 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 air inlet 170.

[0176] In some embodiments, the ventilation part 920 is located on the side of the wind deflector 910 away from the first air outlet 1622. The ventilation part 920 includes a ventilation opening, and a ventilation opening is formed between the extension section 913 and the inner wall of the first chamber 110.

[0177] It can be understood that, in a cross-section perpendicular to the length direction of the box body 100, the ratio of the opening size of the ventilation opening to the opening size of the air duct in the air outlet area 1632 affects the air volume output from the first air outlet 1622 corresponding to the air distribution structure 900.

[0178] In some embodiments, along the length direction of the box body 100, the opening size of the air duct in the air outlet area 1632 gradually decreases in the air flow direction.

[0179] In some embodiments, to adjust the air volume output from the first air outlet 1622 as needed, the ventilation part 920 further includes a moving member. The moving member is movably connected to the wind deflector 910, and the moving member moves relative to the wind deflector 910 to block at least part of the ventilation opening or open the ventilation opening. Exemplarily, the moving member can be rotatably connected or slidably connected to the wind deflector 910.

[0180] It can be understood that, in some embodiments, the box body 100 is configured 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 the at least two first air outlets 1622 are arranged in one-to-one correspondence with the 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 in each hydroponic component 200 are of the same variety but in different growth stages. That is to say, in some cases, the demands of the fruits and vegetables in each hydroponic component 200 for heat, humidity, or carbon dioxide are different. Therefore, an air distribution structure 900 can be arranged in the air outlet area 1632, and the air distribution structure 900 is configured to change the air volume output from the first air outlet 1622. In this way, the air distribution structure 900 is arranged in the air outlet area 1632, which can effectively prevent the air volume output from the first air outlet 1622 from being affected by the obstruction of fruits and vegetables, thus affecting the accuracy of air volume regulation.

[0181] In some embodiments, in order to improve the conditioning efficiency and effect of the air in the second chamber 120, the fan 600 is located in the first area 111 and opposite to the second return air outlet 1611, and the second air outlet 1612 is located below the temperature adjustment device.

[0182] 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 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.
