[0029] The utility model provides a constant temperature and humidity box.

[0030] Please refer to Figures 1 to 4 In an embodiment of the utility model, the constant temperature and humidity box comprises:

[0031] The box body 100 has the constant temperature and humidity cavity 11, and the cavity 11 is used to place materials;

[0032] The anti-rain plate 200 is arranged close to the cavity top wall 111 of the cavity 11, and the anti-rain plate 200 comprises a receiving plate 21, which can receive water droplets condensed from the cavity top wall 111 to avoid the water droplets condensed on the cavity top wall 111 from dropping on the materials.

[0033] In the technical scheme of the utility model, the anti-rain plate 200 receives water droplets condensed from the cavity top wall 111, when the temperature in the cavity 11 is higher than that outside the cavity 11, and the humidity in the cavity 11 is greater than that outside the cavity 11, the water vapor close to the cavity 11 wall exchanges heat with the outside of the cavity 11, and the water vapor in the cavity 11 condenses on the cavity 11 wall, when water droplets condense on the cavity top wall 111, the receiving plate 21 can receive the water droplets dropped from the cavity top wall 111, avoiding the water droplets on the cavity top wall 111 from dropping on the products or materials placed in the cavity 11, and preventing the water droplets from polluting or the products or materials placed in the cavity 11.

[0034] In an embodiment, the anti-dripping plate 200 further comprises two flow guide plates 22 arranged on opposite sides of the receiving plate 21. The flow guide plate 22 comprises a first plate segment 221 connected to the receiving plate 21 and arranged to be inclined downward in a direction close to the cavity side wall 112, so as to roll the water droplets falling on the receiving plate 21 towards the direction close to the cavity side wall 112. The flow guide plate 22 can guide the liquid received on the receiving plate 21 to the position close to the cavity side wall 112, so as to cause the liquid to flow along the cavity side wall 112 or to drip in the cavity 11 at the position close to the cavity side wall 112, thereby avoiding the liquid from dripping in the middle of the cavity 11 and preventing the liquid from excessively accumulating on the receiving plate 21. In other embodiments, the anti-dripping plate 200 can not be provided with the flow guide plate 22.

[0035] In an embodiment, the flow guide plate 22 further comprises a second plate segment 222 connected to the first plate segment 221 and arranged on a side of the first plate segment 221 close to the cavity side wall 112. The extension direction of the second plate segment 222 is parallel to the extension direction of the receiving plate 21. The first plate segment 221 guides the liquid on the receiving plate 21 to the second plate segment 222 and accumulates the liquid on the second plate segment 222. When the liquid accumulated on the second plate segment 222 can spread to the side edge of the second plate segment 222 close to the cavity side wall 112, the liquid can flow along the cavity side wall 112 out of the anti-dripping plate 200 or drip from the side edge of the second plate segment 222 close to the cavity side wall 112. The accumulation of the liquid on the second plate segment 222 can help to reduce the liquid accumulated on the cavity bottom wall 114. In other embodiments, the anti-dripping plate 200 can not be provided with the second plate segment 222.

[0036] In an embodiment, the anti-dripping plate 200 further comprises a first mounting plate 23, and the cavity top wall 111 of the cavity 11 is provided with a second mounting plate 12. The cavity 11 is provided with a cavity front side wall 113 in the thickness direction of the cavity 11. The first mounting plate 23 and the second mounting plate 12 are slidingly connected in the thickness direction of the cavity 11, so as to move the anti-dripping plate 200 close to or away from the cavity front side wall 113. When the anti-dripping plate 200 is moved close to the cavity front side wall 113, the anti-dripping plate 200 is mounted in the cavity 11. When the anti-dripping plate 200 is moved away from the cavity front side wall 113, the anti-dripping plate 200 can be detached from the second mounting plate 12, so as to clean the liquid accumulated on the anti-dripping plate 200. In other embodiments, the anti-dripping plate 200 and the wall of the cavity 11 can be connected by screws.

[0037] In an embodiment, the deflector 22 is provided with a mounting flange 223 at an end close to the cavity side wall 112, the mounting flange 223 is folded towards the cavity top wall 111 and extends towards the direction close to the receiving plate 21, the first mounting plate 23 comprises a mounting plate segment 231 and a sliding plate segment 232 connected together, the extending direction of the mounting plate segment 231 is arranged to be intersected with the extending direction of the sliding plate segment 232, the extending direction of the mounting plate segment 231 is consistent with the extending direction of the mounting flange 223, and the mounting plate segment 231 is connected with the mounting flange 223, the sliding plate segment 232 is in abutment with the second mounting plate 12 and slides on the second mounting plate 12. In production, in order to make the cavity 11 wall be shaped and smoothly demoulded, and to improve the yield, the connecting part between the adjacent cavity 11 walls is provided with a rounded corner or a beveled corner. And since the rainproof plate 200 is arranged close to the cavity top wall 111, in the case that the side edge of the deflector 22 close to the cavity side wall 112 is relatively close to the cavity side wall 112, the mounting flange 223 is folded towards the cavity top wall 111 and extends towards the direction close to the receiving plate 21, so as to make the second mounting plate 12 avoid the connecting part between the cavity top wall 111 and the cavity side wall 112, which is helpful for the shaping of the second mounting plate 12 and is helpful for improving the installation convenience and the installation firmness of the second mounting plate 12 on the cavity top wall 111. Specifically, the mounting flange 223 is folded from the side edge of the second plate segment 222 close to the cavity side wall 112. Further, the mounting flange 223 is connected with the mounting plate segment 231 by screws. In other embodiments, the deflector 22 can not be provided with the mounting flange 223, the first mounting plate 23 is provided with the sliding plate segment 232, a connecting plate segment and the mounting plate segment 231 in abutment with the lower side of the second plate segment 222, the connecting plate segment extends towards the direction close to the receiving plate 21 in the direction close to the cavity top wall 111.

[0038] In an embodiment, the mounting flange 223 and the folded part of the deflector 22 are provided with water outlets 224, and a plurality of water outlets 224 are arranged along the thickness direction of the cavity 11, so as to make the liquid accumulated on the second plate segment 222 flow out. In other embodiments, the second plate segment 222 can not be provided with the water outlets 224, and the liquid accumulated on the second plate segment 222 can also flow out along the cavity front side wall 113 from the side edge of the second plate segment 222 close to the cavity front side wall 113.

[0039] In an embodiment, the second mounting plate 12 comprises a fixed plate segment 121, an inclined plate segment 122 and a sliding plate segment 123 connected in sequence, the fixed plate segment 121 and the sliding plate segment 123 both extend along the extending direction of the receiving plate 21, and the fixed plate segment 121 is connected with the cavity front side wall 113, the inclined plate segment 122 is arranged downwardly from the fixed plate segment 121 to the direction away from the cavity top wall 111, the inclined plate segment 122 can make the sliding plate segment 123 have a sliding gap with the cavity top wall 111, and the sliding plate segment 232 slides and abuts against the sliding plate segment in the sliding gap, so as to make the rainproof plate 200 slide in the thickness direction of the cavity 11. Further, the fixed plate segment 121 and the sliding plate segment extend in opposite directions from the opposite ends of the inclined plate segment 122, so as to facilitate the screw connection of the fixed plate segment 121 and the cavity top wall 111. In other embodiments, the fixed plate segment 121 and the sliding plate segment can also extend in the direction close to the nearest cavity side wall 112 from the opposite ends of the inclined plate segment 122, and the connection mode of the fixed plate segment 121 and the cavity top wall 111 can be glue bonding or welding.

[0040] In an embodiment, the upper end of the cavity 11 is provided with an air inlet 13, the cavity 11 is provided with a cavity front side wall 113 in the thickness direction of the cavity 11, the air inlet 13 is arranged on the cavity front side wall 113, the rainproof plate 200 and the cavity top wall 111 are provided with a steam passage 14, the rainproof plate 200 and the cavity bottom wall 114 of the cavity 11 are provided with a containing space 15, and the material is arranged in the containing space 15. Part of the structure of the air inlet 13 is directed to the steam passage 14, and the other part of the structure of the air inlet 13 is directed to the containing space 15. Steam can enter the cavity 11 through the air inlet 13 to supplement the humidity and temperature in the cavity 11. Part of the steam can pass into the steam passage 14 from the air inlet 13, and part of the steam in the steam passage 14 will exchange heat on the cavity top wall 111, condense into liquid and then drop into the receiving plate 21. Since heat is released during the condensation of steam, the temperature in the steam passage 14 and the containing space 15 tends to be equal, and the water outlet 224 can avoid the accumulation of a large amount of liquid on the rainproof plate 200, and the steam in the containing space 15 can be condensed on the bottom side of the rainproof plate 200. In other embodiments, a heating element can also be arranged in the steam passage 14 to make the temperature in the steam passage 14 greater than or equal to the temperature in the containing space 15.
