Embodiment Construction

[0031] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Such as figure 1 As shown, a method for controlling a frequency conversion range hood according to an embodiment of the present invention includes:

[0033] S10 collects the operation information of the frequency conversion AC motor of the range hood;

[0034] S20 compares the operation information with the stored setting information of the variable frequency AC motor;

[0035] S30 regulates the operating data of the variable frequency AC motor according to the comparison result.

[0036] In this embodiment, by collecting the operating information of the variable frequency AC motor of the range hood, such as the current or power of the variable frequency AC motor, the collected operating information is compared with the stored setting information, and then the operating data of the variable frequency AC motor is adjusted. The embod...

Abstract

The invention discloses a control method and a control system of a variable-frequency extractor hood and the variable-frequency extractor hood. The control method and the control system of the variable-frequency extractor hood aim at achieving high air volume, high total-pressure efficiency and high maximum static pressure, and the rotating speed of fan can be adjusted in a wide range. The controlmethod of the variable-frequency extractor hood in the embodiment comprises the steps of acquiring running information of a variable-frequency AC motor of the extractor hood; comparing the running information and stored set information of the variable-frequency AC motor; and adjusting and controlling the variable-frequency AC motor running data based on the comparing result.

Description

technical field [0001] The invention belongs to the field of range hoods, and specifically relates to a control method, a control system and a frequency conversion range hood for a range hood. Background technique [0002] At present, the range hood AC motor cannot achieve greater effective air volume and air pressure due to the high resistance of the public flue environment. In view of the above-mentioned defect that the frequency conversion of the AC motor cannot be performed, a frequency conversion range hood that uses a frequency conversion motor to adjust the speed of the motor has been disclosed in the prior art. For example, the invention name is an intelligent frequency conversion range hood, the patent number is ZL201420826305.3, and the authorized announcement number is CN 204373022 U. The intelligent frequency conversion range hood disclosed in the Chinese utility model patent includes a smoke collection hood, control components and fans The control component inc...
