Abstract

A partition type ventilator comprises an axial flow impeller, a motor driving the axial flow impeller, and a shell surrounding the axial flow impeller and installed at external wall holes and further comprises a control device for the motor. The control device comprises a switch, a detection circuit and a control circuit, wherein the switch is used for controlling the mode of connecting a motor winding to a power supply, the detection circuit is used for measuring the winding voltage when the motor winding is disconnected from the power supply, and the control circuit is used for driving the switch according to the measurement result of the winding voltage and prescribed process. The partition type ventilator installed on an external wall can adapt to the impact of outdoor wind better when ventilating air toward the outdoor. Compared with a conventional partition type ventilator, the partition type ventilator has the advantages of being more energy-saving and more stable in ventilation.

Description

technical field

[0001] The invention relates to a partition-type ventilating fan, in particular to a control method thereof. In the international patent classification table, the classification may belong to F04D27 / 00. Background technique

[0002] When the traditional partition-type ventilating fan is installed on the exterior wall directly from the indoor to the outdoor exhaust or from the outdoor to the indoor air intake, its working status is greatly affected by the outdoor wind: if the airflow direction driven by the ventilator is the same as the outdoor wind direction, the ventilator will Tends to be light-loaded; if the airflow direction driven by the ventilation fan is opposite to the outdoor wind direction, the ventilation fan tends to be overloaded, causing the ventilation fan to deviate from the set working ventilation state and resulting in energy efficiency loss. Contents of the invention

[0003] The technical problem to be solved by the present invention is ...
