[0027] Reference Figures 1 to 10 A constant temperature and humidity storage cabinet comprises a cabinet body 1, wherein an air duct plate 2 is installed in the cabinet body 1, wherein the air duct plate 2 divides the cabinet body 1 into a storage cavity 3 and a refrigeration cavity, wherein an evaporator 4 and an exhaust device are installed in the refrigeration cavity, wherein an air inlet area 6 is formed at the lower side of the evaporator 4, and a mixing area 7 and an air outlet area 8 connected to the mixing area 7 are formed at the upper side; the air duct plate 2 is provided with a first air inlet 61 corresponding to the air inlet area 6, the air duct plate 2 is provided with a second air inlet 71 corresponding to the mixing area 7, and the air duct plate 2 is provided with an air outlet 81 corresponding to the air outlet area 8. In this embodiment, a mixing zone 7 is provided in the refrigeration chamber. In the mixing zone 7, the cold air that has passed through the evaporator 4 to complete cooling and dehumidification is mixed with part of the original air in the storage chamber, so that the temperature and humidity of the cold air are close to the temperature and humidity of the storage chamber, effectively avoiding the drastic changes in the temperature and humidity of the storage chamber caused by the large difference in the temperature and humidity of the cold air, so that the temperature and humidity of the storage chamber are maintained in a stable state.

[0028] In the utility model, after the exhaust device is started, an upward flowing wind is formed. A part of the air in the storage cavity 3 enters the air inlet area 6 from the first air inlet 61, and then blows through the evaporator 4 to complete cooling and dehumidification to form cold air. Another part of the air enters from the second air inlet 71 and mixes with the cold air to appropriately increase the temperature and humidity of the cold air. The mixed air continues to flow upward into the air outlet area 8 and is blown out from the air outlet 81, forming a complete air cycle.

In this embodiment, not only a fan assembly 5 but also a fan 51 is provided, and the fan 51 can improve the air intake efficiency, so that part of the original air in the storage cavity can be effectively mixed with the cooling and dehumidifying cold air, so that the temperature and humidity in the storage cavity are maintained in a stable state.

[0032] Figure 5 and Figure 6 In the third embodiment, the exhaust device includes a fan 51, a circular second air inlet 71 is provided on the side of the air duct plate 2 facing the mixing zone 7, and the fan 51 is installed at the opening of the second air inlet 71, and a circular first air inlet 61 is provided on the side of the air duct plate 2 facing the air inlet zone 6, and the fan 51 is installed at the opening of the first air inlet 61. In this embodiment, the exhaust device omits the fan assembly 5, so that the mixing zone 7 and the air outlet zone 8 form an integrated space, which reduces the difficulty of assembly and facilitates assembly on the one hand, and increases the mixing space of the air on the other hand, so that the mixed air is closer to the temperature and humidity of the storage cavity, effectively avoiding the drastic changes in the temperature and humidity of the storage cavity caused by the large difference in the temperature and humidity of the cold air.

[0033] Figure 7 and Figure 8 This is the fourth embodiment, the exhaust device includes a fan assembly 5 and two fans 51, the side of the air duct plate 2 facing the mixing area 7 is provided with a circular second air inlet 71 and one of the fans 51 is installed at the opening of the second air inlet 71, the side of the air duct plate 2 facing the air inlet area 6 is provided with a circular first air inlet 61 and another of the fans 51 is installed at the opening of the first air inlet 61. The air circulation effect is better. The installation structure adopts the above method.

[0034] Fig. 9 and Fig.10This is the fifth embodiment, the air extraction device includes a fan 51, a circular air outlet 81 is provided on one side of the air duct plate 2 facing the air outlet area 8, and the fan 51 is installed at the opening of the air outlet 81. In this embodiment, the air extraction device is directly installed at the opening of the air outlet 81, so that the mixing area 7 and the air outlet area 8 form an integrated space, so that the mixed air is closer to the temperature and humidity of the storage cavity, and effectively avoids the drastic change of the temperature and humidity of the storage cavity caused by the large difference in the temperature and humidity of the cold air.
