[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention sprays the condensing agent onto the outer shell of the oven body through the arrangement of the nozzle assembly. The spraying of the condensing agent cools the outer shell of the oven body, thereby cooling the internal driving structure of the oven body to a certain extent, thereby maintaining the high efficiency of the device after long-term use.

[0025] 2. The present invention uses the movement of the blocking block to clamp and position the connected grid frame after rotation adjustment.

When the oven body is baking, the control panel and the switch assembly are used to control and regulate the baking operation of the oven body. The upper limit plate on the fixed plate inside the oven body is connected to the limit plate through the limit slide at the bottom thereof. The placement rack and the limit grid rack are used to place the baked items. When the oven body is baking, the connection grid rack is rotated and closed with the placement rack through the setting of the rotating shaft assembly. At the same time, the rotation and closure of the connection grid rack can hinder the baked items on the placement rack to a certain extent. S3. After the device has been baking for a certain period of time, the driving motor on the box body is powered on, and the output end thereof drives the driving rod to rotate, thereby driving the stirring blade to rotate to stir the condensing agent inside the box body. The box body is provided with a water injection pipe for injecting the condensing agent, and the box body is provided with a glass observation panel for observing the capacity of the condensing agent in the box body. S4. When the device is in use and placed, the support plate and the mounting plate structure separate the four groups of oven bodies. At the same time, the mounting plate is provided with an anti-slip plate, and the surface of the anti-slip plate is provided with anti-slip grooves. The anti-slip grooves on the surface of the anti-slip plate contact the oven body and cooperate with the two groups of positioning plates to clamp the oven body.
