Fume exhaust device and control device thereof

Abstract

The invention discloses a smoke exhaust device and a control method of the smoke exhaust device. The smoke exhaust device includes a cover body, a temperature changing device and a control device. The device is arranged on the body, the temperature changing device includes a temperature changing element, the temperature changing element includes a first temperature changing end that is thermally connected to the smoke collecting cavity, the control device is electrically connected to the temperature changing device, and the When the smoke exhaust device is performing oil fume exhaust work, the control device is used to control the temperature variable element so that the first temperature variable end cools the smoke collection chamber. The control method of the smoke exhaust device includes the steps: the control device receives a smoke exhaust instruction and controls the temperature variable element according to the smoke exhaust instruction so that the first temperature variable end cools the smoke collection cavity; the control The device receives a cleaning instruction and controls the temperature variable element according to the cleaning instruction so that the first temperature variable end heats the smoke collecting cavity.

Description

technical field [0001] The invention relates to the technical field of smoke exhaust, in particular to a smoke exhaust device and a control method for the smoke exhaust device. Background technique [0002] In the related art, the smoke collecting chamber of the range hood condenses the oil fume through direct contact with the oil fume. Since the oil fume has a relatively high temperature, the smoke collecting chamber is not effective in condensing the oil fume, and the oil fume is easy to escape from the smoke collecting chamber, and The uncondensed oily fume is easy to enter into other components (such as volute, impeller, etc.) in the range hood, which will easily have a further negative impact on the use of the range hood and affect user experience. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the related art. Therefore, the present invention needs to provide a smoke exhaust device and a cont...
