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 this 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. Having a home garden can improve this situation. People can eat fresh fruits and vegetables all year round without going out, which is cost-saving, convenient, green and pollution-free. It looks lush and pleasing to the eye, and people can also enjoy the fun of growing and harvesting by themselves, 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 are interconnected. The hydroponic component is arranged in the second chamber. The number of the hydroponic components is at least two, and at least two hydroponic components are arranged at intervals. The temperature regulating device is arranged in the first chamber. The air in the second chamber enters the first chamber through the air return opening, and after being processed by the temperature regulating device, it enters the second chamber through the air outlet. 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 volume of each air outlet, so as to meet the growth requirements 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 stages. Therefore, in some cases, the requirements of fruits and vegetables in each hydroponic component for heat and humidity are different.

[0005] However, during the growth process of fruits and vegetables, the air outlets will be blocked, affecting the air volume. Moreover, the cold and heat of the temperature regulating device are easily directly transmitted to the second chamber through the box body, resulting in a relatively low or high temperature at some local positions in the second chamber.

Detailed implementation

[0058] As shown in the background art, in some cases, the fruits and vegetables in each hydroponic assembly have different requirements for heat and humidity. Moreover, during the growth process of fruits and vegetables, the air outlet will be blocked, affecting the air volume. In addition, the cold and heat of the temperature regulating device are easily directly transmitted to the second chamber through the cabinet, resulting in a lower or higher temperature at a local position in the second chamber.

[0059] To solve the above technical problems, the fruit and vegetable cultivation equipment provided by this application has a first chamber, a second chamber, and a third chamber in the cabinet structure. The third chamber is located between the first chamber and the second chamber. The temperature regulating device is located in the first chamber, and the hydroponic assembly is arranged in the second chamber. The third chamber can effectively prevent the cold or heat of the temperature regulating device from being directly transmitted to the second chamber. Moreover, by arranging the air distribution structure in the air outlet area of the third chamber for air distribution, it can effectively avoid the influence of the air volume of the first air outlet caused by the blockage of fruits and vegetables.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0067] Figure 1 It is a schematic structural diagram of the fruit and vegetable cultivation device provided for the embodiments of the present application. Figure 2 It is a schematic structural diagram of the fruit and vegetable cultivation device provided for the embodiments of the present application after removing the door body. Figure 3 It is a schematic structural diagram of the fruit and vegetable cultivation device provided for the embodiments of the present application after removing the door body and the outer shell.

[0068] See Figures 1 to 3 As shown, the fruit and vegetable cultivation device provided for the embodiments 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.

[0069] In this embodiment, a hydroponic component 200 is provided inside 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.

[0070] 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. The liquid level of the nutrient solution in the hydroponic component 200 can be set according to the types of fruits and vegetables and the requirements during the growth period.

[0071] In some embodiments, in order to facilitate the observation and operation of 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 for the convenience of user operation.

[0072] In some embodiments, the fruit and vegetable cultivation device includes a liquid supply system 700, and the liquid supply system 700 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 into the hydroponic component 200, it flows back to the liquid supply system 700 after flowing through the flow channel of the hydroponic component 200.

[0073] In some embodiments, in order to provide light required for the growth of fruits and vegetables, the fruit and vegetable cultivation device is provided with a lighting component 800, and the lighting component 800 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 that of sunlight, and the amount of light and irradiation time most suitable for the cultivated fruits and vegetables can be set.

[0074] In some embodiments, 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, and at least two lighting components 800 are arranged in one-to-one correspondence with at least two hydroponic components 200.

[0075] 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 inside the box body 100, saving space and improving the space utilization rate.

[0076] In some embodiments, the fruit and vegetable cultivation device includes an air conditioning device, which may 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 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 may include a carbon dioxide generator.

[0077] In some embodiments, a display component is provided outside the box 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, and the control panel 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 100.

[0078] In some embodiments, the fruit and vegetable cultivation device includes a fan, and the fan is arranged in the box 100. The fan drives the air to flow, so as to realize the air circulation in the box 100.

[0079] In some embodiments, the fruit and vegetable cultivation device includes a fan, and the fan is arranged in the box 100. The fan drives the air to flow, so as to realize the circulation of the air between the box 100 and the external air.

[0080] [Box structure]

[0081] Figure 4 FIG. is a schematic structural diagram of the first box in the fruit and vegetable cultivation device provided by the embodiment of the present application.

[0082] See Figure 4 As shown, in some embodiments, to realize the air circulation in the box 100, the box 100 is constructed with a first chamber 110 and a second chamber 120.

[0083] The box 100 is constructed with a first air return opening 1621 and a first air outlet 1622. The first air return opening 1621 is communicated with the first chamber 110 and is also communicated with the second chamber 120. The first air outlet 1622 is communicated with the first chamber 110 and is also communicated with the second chamber 120.

[0084] The fan 600 is arranged in the first chamber 110 or the second chamber 120. When the fan 600 rotates, it drives the air in the first chamber 110 to flow through the first air outlet 1622 into the second chamber 120, and the air in the second chamber 120 flows through the first air return opening 1621 into the first chamber 110.

[0085] In some embodiments, in order to improve the space utilization rate, the hydroponic component 200 is arranged in the second chamber 120, and the fan 600 is arranged in the first chamber 110.

[0086] 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.

[0087] Specifically, the air conditioning device may include a refrigeration system. The evaporator 410 of the refrigeration system is disposed 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 blower 600.

[0088] 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. The dehumidified air flows into the second chamber 120 under the action of the blower 600.

[0089] In some embodiments, the cabinet 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 cabinet 100. Therefore, in order to facilitate the pipeline connection between the evaporator 410 and devices such as the compressor, the evaporator is located at a position close to the bottom of the first chamber 110 to reduce the distance from the compressor compartment.

[0090] In some embodiments, in order to save the space of the first chamber 110, the blower 600 is located above the evaporator 410, 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 blower 600 and the evaporator 410 being arranged front and back 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.

[0091] 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. The heated air flows into the second chamber 120 under the action of the blower 600.

[0092] It can be understood that the heating element can also accelerate the evaporation of moisture, thereby being used to increase the humidity of the air in the second chamber 120.

[0093] Exemplarily, the heating element can be a heating wire or a heating sheet.

[0094] In some embodiments, the heating element is disposed at a position close to 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 can be provided at the bottom of the first chamber 110 to discharge the defrosting water into the evaporating dish in the compressor compartment.

[0095] In some embodiments, the air conditioning device further includes a carbon dioxide generator located in the first chamber 110, and the carbon dioxide generator is used to generate carbon dioxide to meet the growth requirements of fruits and vegetables.

[0096] In some embodiments, the first air return opening 1621 and the first air outlet 1622 are arranged at intervals along the length direction of the box body, and the first air return opening 1621 is located above the first air outlet 1622. Since heat is generated during the growth of fruits and vegetables and heat is also generated when the lighting component works, the hot air in the second chamber 120 moves upward. In this way, under the action of the fan and the rising hot air, the efficiency of air circulation is relatively high, which is beneficial to energy conservation.

[0097] In some embodiments, the number of the first air outlets 1622 is at least two, the first air return opening 1621 and the 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 the at least two first air outlets 1622 along the length direction of the box body. For example, the first air return opening 1621 is located above the 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 the at least two first air outlets 1622 along the length direction of the box body 100.

[0098] Under the action of the fan 600 in the box body 100, the air in the second chamber 120 returns to the second chamber 120 in sequence through the first air return opening 1621, the first chamber 110, and the first air outlet 1622.

[0099] 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 output of each first air outlet 1622 is 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.

[0100] Therefore, in this embodiment, in order to improve the air uniformity in the second chamber 120. From the direction away from the first air return opening 1621 to the direction close to the first air return opening 1621, the air output of the first air outlet 1622 gradually decreases.

[0101] 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 unsmooth. When the air volume of the one farther from the first air return opening 1621 is greater than 3 times that of the other, on 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.

[0102] 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 greater 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.

[0103] Exemplarily, when the number of first air outlets 1622 is 3, 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.

[0104] 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.

Figure 6 It 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.

[0106] See Figures 4 to 6 As shown, in another possible implementation manner, it further includes an air distribution structure 900. The air distribution structure 900 is located in the first chamber 110, and the air distribution structure 900 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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 .

[0113] 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.

[0114] It can be understood that, in a cross-section along the length direction perpendicular to the cabinet 100, the ratio of the opening size of the ventilation opening to the opening size of the air duct in the first chamber 110 affects the air volume output of the first air outlet 1622 corresponding to the air distribution structure 900.

[0115] In some embodiments, along the length direction of the cabinet 100, the opening size of the air duct in the first chamber 110 gradually decreases along the air flow direction.

[0116] Figure 7 This is a schematic structural diagram of the second type of cabinet in the fruit and vegetable cultivation equipment provided by the embodiments of the present application.

[0117] 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. Here, taking the example where 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 first chamber 110 is smaller along the depth direction of the cabinet 100. For example, the size of the first chamber 110 along the depth direction of the cabinet 100 is 10 to 30 cm.

[0118] Therefore, when the evaporator 410 or the heating element is working, 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 100, resulting in local overcooling or overheating in the second chamber 120.

[0119] To solve the above technical problems, in some embodiments, the cabinet 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 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.

[0120] The cabinet 100 is configured with a first return air opening 1621 and at least two spaced-apart first air outlets 1622. The first return air opening 1621 communicates with the second chamber 120 and the return air area 1631, and the first air outlets 1622 communicate with the second chamber 120 and the air outlet area 1632.

[0121] The cabinet 100 is configured with a second return air opening 1611 and a second air outlet 1612. The second return air opening 1611 communicates with the first chamber 110 and the return air area 1631, and the second air outlet 1612 communicates with the first chamber 110 and the air outlet area 1632.

[0122] The blower 600 is located inside the cabinet 100. Exemplarily, the blower 600 can be located in the first chamber 110, or the return air area 1631, or the air outlet area 1632, etc. Under the action of the blower 600, the air in the second chamber 120 flows back into the second chamber 120 in sequence through the first return air inlet 1621, the return air area 1631, the second return air inlet 1611, the first chamber 110, the second air outlet 1612, the air outlet area 1632, and the first air outlet 1622.

[0123] The hydroponic component 200 is arranged at intervals inside the second chamber 120. The temperature regulating device is arranged inside the first chamber 110.

[0124] It can be understood that by providing the third chamber 163, the uniformity of the distribution of the first air outlet 1622 can be improved. The following takes the example that the first return air inlet 1621 is located above at least two first air outlets 1622 along the length direction of the cabinet 100 for illustration. When the third chamber 163 is provided, the air in the second chamber 120 enters the first chamber 110 through the first return air inlet 1621, the return air area 1631, and the second return air inlet 1611, moves downward along the first chamber 110, then enters the air outlet area 1632 through the second air outlet 1612, 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 inlet 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. That is to say, the first air outlet 1622 can only be provided at a position in the lower part of the first chamber 110, and an air regulating device is provided at a position in 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 the number of the first air outlets 1622 that can be provided can be increased when the size of the second chamber 120 along the length direction of the cabinet is certain.

[0125] It can be understood that, referring to 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.

[0126] 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.

[0127] 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 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. The extension section 913 is spaced from the inner wall of the air outlet area 1632 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.

[0128] 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 air outlet area 1632 form the vent. In this way, the structure is simpler and occupies less space.

[0129] It can be understood that, in a cross-section along the length direction perpendicular to 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 of the first air outlet 1622 corresponding to the air distribution structure 900.

[0130] 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 along the air flow direction.

[0131] 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 part, which is movably connected to the wind blocking part 910. The moving part moves relative to the wind blocking part 910 to block at least part of the ventilation opening or open the ventilation opening. Exemplarily, the moving part can be rotatably connected or slidably connected to the wind blocking part 910.

[0132] In some embodiments, in order to improve the air conditioning efficiency and effect of the air in the second chamber 120, the fan 600 is located in the first chamber 110 and is opposite to the second air return opening 1611. The air conditioning device is located below the fan 600, and the second air outlet 1612 is located below the air conditioning device.

[0133] In some embodiments, an arc-shaped guiding part 1613 is provided at the bottom of the second air outlet 1612. The arc-shaped guiding part 1613 is used to guide the air to flow obliquely upward to enter the air outlet area 1632. Among them, the projection length of the arc-shaped guiding part 1613 in the vertical direction should not be less than the projection length of the second air outlet 1612 in the vertical direction. In this way, the direction of the air flow can be guided efficiently, and the air supply efficiency can be improved.

[0134] In some embodiments, in order to effectively prevent the first air outlet 1622 from directly blowing on the roots of fruits and vegetables and affecting the growth of fruits and vegetables. At least two first air outlets 1622 are provided in one-to-one correspondence with at least two hydroponic components 200. At least two first air outlets 1622 are respectively located above the corresponding hydroponic components 200, and the distance from the corresponding hydroponic components 200 is greater than one-third of the distance between adjacent two hydroponic components 200. Exemplarily, it is greater than half of the distance between adjacent two hydroponic components 200.

[0135] In some embodiments, at least three hydroponic components 200 are arranged at intervals along the length direction of the box body 100. 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. 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.

[0136] The number of the hydroponic components 200 is the same as the sum of the numbers of the first air return openings 1621 and the first air outlet openings 1622. The first air return openings 1621 and at least two first air outlet openings 1622 are arranged in one-to-one correspondence with at least three hydroponic components 200. The first air return openings 1621 and at least two first air outlet openings 1622 are respectively located above the corresponding hydroponic components 200, and the distance from them to the corresponding hydroponic components 200 is greater than one-third of the distance between two adjacent hydroponic components 200. Exemplarily, it can be greater than half of the distance between two adjacent hydroponic components 200.

[0137] In some embodiments, the cabinet 100 includes: a housing, an inner tank, and an air duct assembly 160. The inner tank is located inside the housing. The air duct assembly 160 is located inside the inner tank.

[0139] See Figures 8 to 12 As shown in

[0140] The air duct assembly 160 includes a first partition 161 and a second partition 162. The first partition 161 and the second partition 162 are arranged in sequence along the depth direction of the cabinet 100. The space between the first partition 161 and the inner bottom wall of the inner tank is the first chamber 110. The space between the second partition 162 and the first partition 161 is the third chamber 163. The space on the side of the second partition 162 away from the first partition 161 is the second chamber 120.
