[0038] Embodiment 1

[0039] As Figures 1-9As shown in the figure, this embodiment provides a vending machine, which includes a cabinet 1, a wind guiding device 2, a refrigeration device 3 and a heating device 4. Among them, a storage area is provided in the cabinet 1, and the storage area includes an upper storage area and a lower storage area arranged in the vertical direction; the wind guiding device 2 includes an upper air duct plate 21 and a lower air duct plate 22 that extend and are arranged side by side in the vertical direction. Both the upper air duct plate 21 and the lower air duct plate 22 are opposite to the side wall of the storage area. An upper air duct 25 is formed between the upper air duct plate 21 and the side wall. The upper end of the upper air duct plate 21 and the side wall form a first upper end opening 251, and the lower end of the upper air duct plate 21 and the side wall form a first lower end opening 252. A lower air duct 26 is formed between the lower air duct plate 22 and the side wall. The upper end of the lower air duct plate 22 and the side wall form a second upper end opening 261, and the lower end of the lower air duct plate 22 and the side wall form a second lower end opening 262. The second upper end opening 261 is arranged opposite to the first lower end opening 252; the wind guiding device 2 further includes a wind blocking door 23. An air return opening 216 is provided on the surface of the upper air duct plate 21. The wind blocking door 23 has an open position and a closed position. When the wind blocking door 23 is in the closed position, the wind blocking door 23 closes the air return opening 216, and the upper air duct 25 is communicated with the lower air duct 26. When the wind blocking door 23 is in the open position, the wind blocking door 23 opens the air return opening 216, and the wind blocking door 23 extends into the upper air duct 25 and abuts against the side wall to block the upper air duct 25 from communicating with the lower air duct 26; the refrigeration device 3 is arranged below the lower storage area and communicated with the second lower end opening 262, and the heating device 4 is arranged above the upper storage area and communicated with the first upper end opening 251.

[0040] The vending machine provided in this embodiment has a refrigeration mode and a heating mode. As Figure 2 shown, in the refrigeration mode, the heating device 4 does not work, the refrigeration device 3 works, the wind blocking door 23 is in the closed position, the upper air duct 25 is communicated with the lower air duct 26, and the cold air of the refrigeration device 3 is blown into the lower air duct 26 from the second lower end opening 262 of the lower air duct 26, flows along the lower air duct 26, enters the upper air duct 25 through the second upper end opening 261 of the lower air duct 26 and the first lower end opening 252 of the upper air duct 25, and flows out from the first upper end opening 251 of the upper air duct 25. When flowing along the lower air duct 26 and the upper air duct 25, it enters the lower storage area and the upper storage area through the ventilation openings 28 on the lower air duct plate 22 and the upper air duct plate 21. When the cold air flowing along the upper air duct 25 and the lower air duct 26 blows to the top of the upper storage area, the cold air flows along the top to the other side of the storage area and then flows downward, and returns to the refrigeration device 3, forming a cold air circulation in the entire storage area. As Figure 3As shown, when the heating mode is adopted, the heating device 4 operates, the refrigeration device 3 does not operate, the windshield door 23 is in the open position, the air return opening 216 is opened, and the upper air duct 25 and the lower air duct 26 are blocked. The air in the upper air duct 25 is heated by the heating device 4 along the upper air duct 25 and then flows along the top of the upper storage area. After flowing to the other side of the upper storage area, it flows downward. When it flows to the position opposite to the air return opening 216, it is sucked into the upper air duct 25 by the air return opening 216, forming a hot air circulation in the upper storage area. At the same time, the lower storage area remains at room temperature. The vending machine provided in this embodiment opens the air return opening 216 on the surface of the upper air duct plate 21. When in the heating mode, the windshield door 23 opens the air return opening 216, enabling the air in the upper storage area to quickly enter the upper air duct 25. The hot air circulates rapidly in the upper storage area, and the upper storage area can be quickly heated. At the same time, the windshield door 23 also blocks the upper air duct 25 and the lower air duct 26, preventing the air in the lower storage area and the lower air duct 26 from entering the upper air duct 25 through the first lower end opening 252 of the upper air duct 25, avoiding heat exchange with the lower storage area, and ensuring the heating efficiency of the heating device 4 for the upper storage area.

With the above arrangement, the flow area of the upper air duct 25 is effectively guaranteed, and the air flow velocity in the upper air duct 25 is also guaranteed, thereby ensuring the heating efficiency of the heating device 4 for the upper storage area.

[0045] Optionally, in this embodiment, as Figure 6 and Figure 7 shown, the upper air duct plate 21 further includes a first fixing plate 213, a second fixing plate 214, and a third fixing plate 215. The first fixing plate 213 is connected at an angle to one side of the first plate 211, and the first fixing plate 213 is used to connect to the rear wall 115. The second fixing plate 214 is connected at an angle to one side of the second plate 212, and the second fixing plate 214 is used to connect to the first side wall 111. The third fixing plate 215 is connected at an angle to the other side of the first plate 211, and the third fixing plate 215 is used to connect to the top wall 113. With the above structural design of the upper air duct plate 21, not only the structural strength of the upper air duct plate 21 is guaranteed, but also the stability and reliability of the connection between the upper air duct plate 21 and the cabinet body 11 are guaranteed. In other embodiments, the upper air duct plate 21 can be fixedly connected to the first side wall 111 and the rear wall 115 by means of plugging or welding.

[0046] Optionally, in this embodiment, as Figure 2 、 Figure 8As shown, the lower air duct plate 22 includes a third plate 221 and a fourth plate 222 connected at an angle. The third plate 221 is disposed opposite and spaced apart from the first side wall 111, and the fourth plate 222 is disposed opposite and spaced apart from the rear wall 115. The third plate 221, the fourth plate 222, the first side wall 111, and the rear wall 115 together define a lower air duct 26 extending in the up-down direction; the refrigeration device 3 includes at least two evaporator fans 31, and the at least two evaporator fans 31 are spaced apart in the front-rear direction and are both disposed adjacent to the second lower end opening 262 of the lower air duct 26. The above arrangement effectively ensures the flow area of the lower air duct 26, also ensures the air flow speed in the lower air duct 26, and ensures the refrigeration effect of the refrigeration device 3 on the entire storage area.

[0047] Optionally, in this embodiment, the length of the wind blocking door 23 matches the length of the first plate 211, and the width of the wind blocking door 23 is greater than or equal to the width of the second plate 212.
