[0035] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] First refer to Figure 1-3 , Figure 1 It is a three-dimensional structural schematic diagram of a modular and adjustable vegetable cabinet in an embodiment of the utility model (cabinet door omitted); Figure 2 This is a front view of a modular and adjustable vegetable cabinet in an embodiment of the utility model (the cabinet door is omitted); Figure 3 It is a cross-sectional view of a modular and adjustable vegetable cabinet in an embodiment of the utility model.

[0037] like Figure 1-3As shown, the vegetable cabinet in this embodiment includes a cabinet body 1, and a plurality of independent storage chambers 11 are arranged in the cabinet body 1, and a first air supply port 111 and a first air return port 112 are respectively arranged on the rear panel 110 of each storage chamber 11. The cabinet body 1 also includes a partition 12 arranged in each storage chamber, and the upper side wall, lower side wall, left side wall and right side wall of the partition 12 are respectively against the upper inner wall, lower inner wall, left inner wall and right inner wall of the storage chamber 11, and the partition 12 is provided with a second air supply port 121 opposite to the first air supply port 111, and a second air return port 122 opposite to the first air return port 112. A first elastic pipe 13 for covering the first air supply port 111 and the second air supply port 121, and a second elastic pipe 14 for covering the first air return port 112 and the second air return port 122 are arranged between the partition 12 and the rear panel 110 of the storage chamber 11. The first elastic tube 13 and the second elastic tube 14 can extend / contract to drive the partition 12 to move forward and backward, thereby compressing / expanding the available space of the storage chamber 11 .

[0038] Specifically, a partition 12 is provided in the independent storage chamber 11 of the cabinet 1 of the present embodiment, and the outer dimensions of the partition 12 are adapted to the inner dimensions of the storage chamber, and then a first elastic pipe 13 and a second elastic pipe 14 are provided between the partition 12 and the rear panel 110, so that when a large number of fruits and vegetables are placed in the storage chamber 11, the partition 12 is pushed to compress the first elastic pipe 13 and the second elastic pipe 14 backward, and then the fruits and vegetables (for example, packaged tomatoes, potatoes, cucumbers, etc.) are pressed against the front wall of the partition 12, and the partition 12 is fixed at the current position by the resistance of the fruits and vegetables themselves, so that the available space in the storage chamber 11 can meet the storage needs of the fruits and vegetables. Further, when the storage chamber 11 has a small amount of fruits and vegetables, for example, after taking away the fruits and vegetables pressed against the front wall of the partition 12, the partition 12 can move forward under the thrust of the first elastic pipe 13 and the second elastic pipe 14, thereby reducing the available space of the storage chamber 11 to meet the storage needs of less fruits and vegetables. Those skilled in the art can understand that the elasticity of the first elastic tube 13 and the second elastic tube 14 can be set with a reasonable elastic coefficient according to actual conditions, so that after generally packaged fruits and vegetables are placed on the front wall of the partition 12, the partition 12 can be blocked from moving forward under the elastic force of the first elastic tube 13 and the second elastic tube 14. At the same time, after the fruits and vegetables on the front wall of the partition 12 are taken away, the partition 12 can move forward under the elastic force of the first elastic tube 13 and the second elastic tube 14 until it encounters the next resistance (such as other fruits and vegetables in the storage chamber 11) and then stops moving.

[0039] The above design can save energy consumption in the refrigeration system. In this embodiment, the refrigeration system may include a compressor, a condenser, an evaporator and connecting pipes. The compressor, condenser and evaporator are connected through connecting pipes to realize a refrigeration cycle. The working principles of the compressor, condenser and evaporator are not described here. Among them, the compressor and the condenser are arranged on the top of the cabinet 1. Specifically, a protective cover 15 is provided on the top of the vegetable cabinet. The compressor and the condenser are located in the protective cover 15. The compressor and the condenser in the protective cover 15 are not shown in the figure. More specifically, see Figure 4 , Figure 4 1 is a schematic diagram of the rear perspective structure of a modular adjustable vegetable cabinet in the embodiment of the utility model. The refrigeration system of the embodiment also includes a refrigeration compartment arranged at the bottom of the cabinet body 1, such as Figure 4 As shown, the back of the cabinet 1 is provided with an air supply channel 31 connected to the refrigeration compartment, and a return air channel 32, the air supply channel 32 is connected to the first air supply port 111 of each storage chamber 11, and the return air channel 32 is connected to the first return air port 112 of each storage chamber 11. The evaporator is located in the refrigeration compartment, so that when the outside air enters the refrigeration compartment, the evaporator absorbs the heat of the air and converts it into cold air, and then enters the first elastic duct 13 through the air supply channel 31, and then enters the storage chamber 11 through the second air supply port 121; the air in the storage chamber 11 enters the second elastic duct 14 through the second return air port 122, and then enters the return air channel 32 through the first return air port 112 to flow out. This embodiment does not describe the specific refrigeration system in detail, but only describes the layout of the air supply channel 31 and the return air channel 32 on the cabinet. In this embodiment, the storage chambers 11 in the cabinet 1 are arranged in at least two rows in a horizontal row and at least three rows in a vertical row. Those skilled in the art can arrange more storage chambers 11 in a horizontal row and / or a vertical row according to actual needs.

[0040] In this embodiment, due to the provision of the first elastic duct 13 and the second elastic duct 14, cold air can directly enter the available space of the storage chamber 11 through the first air supply port 111, and will not enter the space between the partition 12 and the rear panel 110. In this way, when the available space of the storage chamber 11 is small, less cold air is required, and when the available space of the storage chamber 11 becomes larger, the cold air is increased accordingly. In this way, the size of the storage chamber 11 can be adjusted according to the amount of fruits and vegetables placed in the storage chamber 11, thereby effectively reducing the cold air consumption of the refrigeration equipment.

[0041] Optionally, the first air supply port 111 and the second air supply port 121 are respectively provided with a first one-way air inlet door and a second one-way air inlet door, which are used to allow the air in the air supply channel 31 to pass through the first one-way air inlet door and the second one-way air inlet door in sequence and enter the storage chamber 11; the first return air port 112 and the second return air port 122 are respectively provided with a first one-way return air door and a second one-way return air door, which are used to allow the air in the storage chamber 11 to pass through the second one-way air inlet door and the first one-way return air door in sequence and flow into the return air channel 32. This embodiment does not describe the structures of the one-way air inlet door and the one-way return air door in detail, and those skilled in the art can design a reasonable structure to achieve the corresponding one-way air inlet or one-way air outlet function.

[0042] In a specific embodiment, referring to Figure 5-6 ,like Figure 5 and Figure 6 As shown, the partition 12 is provided with an annular edge extending backwards around it, which is used to guide the partition 12 to move forward and backward, and prevent the partition 12 from being skewed during the movement due to its thinness. Specifically, the upper side wall of the partition 12 extends backwards to form an upper supporting edge 123, the lower side wall of the partition 12 extends backwards to form a lower supporting edge 124, the left side wall of the partition 12 extends backwards to form a left supporting edge 125, and the right side wall of the partition 12 extends backwards to form a right supporting edge 126, so that the upper supporting edge 123 abuts against the upper inner wall of the storage chamber 11, the lower supporting edge 124 abuts against the lower inner wall of the storage chamber 11, the left supporting edge 125 abuts against the left inner wall of the storage chamber 11, and the right supporting edge 126 abuts against the right inner wall of the storage chamber 11, thereby guiding the partition 12 to move forward and backward, and preventing the partition 12 from being skewed during the movement forward and backward. As an example, the first elastic pipe 13 and the second elastic pipe 14 can be set as elastic bellows with a threaded spring built in the elastic bellows. The elastic bellows are used to cover the two relative return air ports and air inlet ports, which can effectively prevent cold air from entering the space between the partition 12 and the rear panel 110.

[0043] In a more specific embodiment, referring to Figure 6 The partition 12 is also provided with an air pressure balance valve 127, which is used to balance the air pressure of the first space and the external space; wherein the first space is the space between the partition 12 and the rear panel 110 of the storage chamber 11. As an example, refer to Figure 7 and Figure 8 ,like Figure 7 and Figure 8As shown, the air pressure balance valve 127 includes a first valve body 1271, a second valve body 1272, and a first diaphragm 1273 and a second diaphragm 1274 disposed between the first valve body 1271 and the second valve body 1272. A first through hole 1275 is disposed on the first valve body 1271, and a second through hole 1276 is disposed on the second valve body. The first diaphragm 1273 and the second diaphragm 1274 are attached to each other to isolate the first space from the external space. In this way, when the air pressure in the first space is higher than the air pressure in the external space, the air in the first space will push the first diaphragm 1273 and the second diaphragm 1274 open under the action of pressure, so that the first space and the external space are connected to balance the air pressure; when the air pressure in the first space is lower than the air pressure in the external space, the air in the external space will push the first diaphragm 1273 and the second diaphragm 1274 open under the action of pressure, so that the first space and the external space are connected to balance the air pressure.

[0044] Optionally, a support seat 16 is respectively provided at the four corners of the bottom of the cabinet 1 for supporting the cabinet.

[0045] In summary, a partition 12 that can move forward and backward is provided in the independent storage chamber 11 of the cabinet 1 of the present embodiment, and a first elastic pipe 13 and a second elastic pipe 14 are provided between the partition 12 and the rear panel 110. In this way, when a large number of fruits and vegetables are placed in the storage chamber 11, the partition 12 is pushed to compress the first elastic pipe 13 and the second elastic pipe 14 backward, and then the fruits and vegetables (for example, packaged tomatoes, potatoes, cucumbers, etc.) are pressed against the front wall of the partition 12, and the partition 12 is fixed at the current position by using the resistance of the fruits and vegetables themselves, so that the available space in the storage chamber 11 can meet the storage needs of the fruits and vegetables. Further, when the storage chamber 11 has a small amount of fruits and vegetables, for example, after taking away the fruits and vegetables against the front wall of the partition 12, the partition 12 can move forward under the thrust of the first elastic pipe 13 and the second elastic pipe 14, thereby reducing the available space of the storage chamber 11 to meet the storage needs of less fruits and vegetables. Those skilled in the art can understand that the elasticity of the first elastic tube 13 and the second elastic tube 14 can be set with a reasonable elastic coefficient according to actual conditions, so that after generally packaged fruits and vegetables are placed on the front wall of the partition 12, the partition 12 can be blocked from moving forward under the elastic force of the first elastic tube 13 and the second elastic tube 14. At the same time, after the fruits and vegetables on the front wall of the partition 12 are taken away, the partition 12 can move forward under the elastic force of the first elastic tube 13 and the second elastic tube 14 until it encounters the next resistance (such as other fruits and vegetables in the storage chamber 11) and then stops moving.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
