A ventilation fan with humidification function for winter

Abstract

The invention discloses a ventilation fan with a humidifying function for winter. The ventilation fan comprises a ventilation fan body, a control circuit, a humidifying device, a ventilation switch and a humidifying switch; the temperature is measured through a temperature sensor, the temperature value is sent to the control circuit, the control circuit carries out contrastive analysis on the temperature value and outputs a command, if the temperature surpasses the set upper limit value, the ventilation switch can be triggered automatically to exchange air for the inside; the humidity is measured through a humidity sensor, the humidity value is sent to the control circuit, the control circuit carries out contrastive analysis on the humidity value and outputs a command, if the humidity is lower than the set lower limit value, the humidifying switch can be triggered automatically to humidify the inside so as to control the indoor temperature and humidity in a range which makes people feel comfortable. In general, the ventilation is performed before humidifying. The water level in a water tank is monitored through a liquid level sensor, if the water level in the water tank is lower than the lowest water line, a main power of the ventilation fan is cut off automatically to protect the equipment.

Description

technical field [0001] The invention relates to the field of ventilating fans, in particular to a ventilating fan with humidification function for winter use. Background technique [0002] Now, common university student dormitories are equipped with heating, which facilitates the life of students on the one hand, but also brings some problems. Heating is supplied 24 hours a day, which sometimes causes the indoor temperature to be too high, and the indoor air is not fresh due to lack of timely ventilation. During the day, people need to manually open the windows for ventilation, but after opening the windows for ventilation, the indoor temperature is as cold as the outside temperature, causing inconvenience; At night, people close the doors and windows when they sleep, but the indoor air is dry and hot due to lack of ventilation for a long time, people feel irritable, and the quality of sleep is not good. Adverse reactions. The current ventilation fan needs to be turned on ...

Problems solved by technology

Heating is supplied 24 hours a day, which sometimes causes the indoor temperature to be too high, and the indoor air is not fresh due to lack of timely ventilation. During the day, people need to manually open the windows for ventilation, but after opening the windows for ventilation, the indoor temperature is as cold as the outside temperature, causing inconvenience; At night, people close the doors and windows when they sleep, but the indoor air is dry and hot due to lack of ventilation for a long time, people feel irritable, and the quality of sleep is not good. Adverse reactions

The current ventilation fan needs to be turned on actively by a person, and has no humidification function
