Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 The shown delay shutdown control device for range hoods includes a controller 4 for controlling fan gears, a smoke sensor 1, a temperature sensor 2 and a humidity sensor 3 connected to the controller 4, wherein the smoke sensor 1 is used for Collect smoke particle data in the kitchen, temperature sensor 2 is used to collect the temperature data of the stove head area under the range hood, and humidity sensor 3 is used to collect humidity data in the kitchen. When the range hood chooses to delay shutdown, the controller During the preset shutdown delay time, as time goes by, the fan gear is gradually reduced according to the data collected by the smoke sensor, temperature sensor, and humidity sensor. When the preset delay shutdown time expires, it will be turned off fan.

[0022] Specifically, the gear position of the ...

Abstract

The invention relates to a delayed shutdown control device, a control method and a range hood. The delayed shutdown control device is characterized by comprising a controller used for controlling the gear of a fan; after the range hood selects delayed shutdown, the controller gradually reduces the gear of the fan as time goes on within a preset delayed shutdown time; and after the preset delayed shutdown time expires, the fan is turned off. Compared with the prior art, the control method has the advantages that the gear of the fan can be gradually reduced as time goes on within the preset delayed shutdown time, and the fan is turned off after the preset delayed shutdown time expires, so that unnecessary resource waste is avoided, and meanwhile, the cleanness of a kitchen environment is guaranteed.

Description

technical field [0001] The invention relates to a delay shutdown control device of a range hood and a control method thereof, and a range hood with a delay shutdown function. Background technique [0002] There is a range hood with a delay shutdown function on the market. After the user finishes cooking, many users will choose the delay shutdown function. When the delay shutdown mode is selected, the range hood will not adjust the gear, but with Fixed gear to run for a period of time. When the delay shutdown time is set too large, it will cause a certain waste of resources. When the delay shutdown time is set too small, it will cause incomplete extraction of oil fume. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide a delay shutdown control device capable of adjusting the fan gear as time goes by in view of the above-mentioned prior art. [0004] The second technical problem to be solved by the present in...
