Description

Technical Field

[0001] The utility model relates to the technical field of drying ovens, in particular to a drying oven for uniform drying. Background Art

[0002] An oven is an electrical appliance that can dry items. It is usually made of steel plates, and the heater can be installed at the bottom of the oven, or on both sides or the top of the oven. The oven is usually equipped with a temperature controller to control the baking temperature. The working principle of the oven is to use a fan to draw external air into the heating layer of the oven. The air becomes hot through the heating of the heater and enters the oven to heat the items, that is, to dry the items and vaporize the moisture in the items.

[0003] The existing patent (publication number: CN209623243U) discloses an energy-saving oven, including an oven liner, a side end surface of the oven liner is provided with a circular groove 1, an inner wall of the oven liner is fixedly connected with a support bar, an upper end of the support bar is movably connected with a tray, an outer side of the oven liner is fixedly connected with a heat insulation layer, a heating layer is fixedly connected between the oven liner and the heat insulation layer, a heating tube is fixedly connected at the lower end of the heating layer, a fan is fixedly connected at the side end of the heat insulation layer, a support foot is fixedly connected at the lower end of the heat insulation layer, an instrument panel is fixedly connected at the front end of the heat insulation layer, and an air inlet is provided at the lower end of the heat insulation layer. The energy-saving oven is provided with a square groove and a partition in the middle of the oven. When there are fewer items to be dried, the partition 1 can block the square groove 1 and the square groove 2, so that the oven is divided into two, and the wind source is only heat-circulated in the hollow structure inside the heating layer and the partition 1 on one side, thereby improving the drying efficiency and saving energy. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The heating layer of the existing drying oven is arranged on one side of the interior, which results in a slower drying speed for the items on the side away from the heating layer and an uneven drying speed for the items inside, which easily leads to the problem that some items are dried while others are not completely dried; 2. The distance between the trays of the existing drying oven is fixed, but the sizes of the items to be dried in each batch are different, making it inconvenient to adjust the spacing between the trays according to the size of the items.
