Description

Technical Field

[0001] The utility model relates to the technical field of drying ovens, in particular to a new type of constant temperature drying oven. Background Technique

[0002] The constant temperature drying oven is an essential test equipment in the fields of aviation, automobiles, household appliances, scientific research, etc., and is used to test and determine the parameters and performance of electrical, electronic and other products and materials after the temperature environment changes during high-temperature tests.

[0003] In the prior art, a Chinese patent with the publication number CN207247750U discloses a remote-controlled electrothermal constant temperature drying oven, which includes a box body and a box door hinged to the side of the box body; a heat preservation layer is arranged in the box body, a drying chamber is arranged in the heat preservation layer, and a plurality of partition boards are slidably installed on the inner wall of the drying chamber. This device can recover and utilize the energy in the hot air discharged from the drying chamber, and can also dry the hot air that is about to be circulated in the hot air dryer to avoid water vapor from entering the drying chamber. Compared with the traditional remote-controlled electrothermal constant temperature drying oven, it not only shortens the drying time but also improves the drying efficiency.

[0004] However, the partition boards in the above device are slidably connected to the inner wall of the drying chamber. When the size of the products placed on the partition boards is relatively large, it is necessary to take out the upper partition boards to provide enough space for the products. In this way, the removed partition boards need to be placed separately, which may lead to the loss of the partition boards. Moreover, the dried objects are at a relatively high temperature after drying, which may cause burns and need to be cooled for a long time before they can be taken out, reducing the work efficiency. Therefore, it does not meet the existing requirements, and for this reason, we propose a new type of constant temperature drying oven. Content of the Utility Model
