A window-type ventilation device is disclosed. A window-type ventilation device according to the present invention enables: polluted indoor air and outdoor air to be introduced into a housing; the introduced polluted indoor air and outdoor air to undergo heat exchange so that a part of air after the heat exchange is introduced into a room and the other part of the air after the heat exchange is discharged to the outside of the room; and even when moisture such as rain water, etc. is introduced into the housing, the introduced moisture to be easily discharged to the outside of the ventilation device by a moisture permeation-proof member.

A purpose of the present invention is to provide a flow guide for noise reduction and a device for reducing noise, wherein noise can be reduced effectively without disturbing the air flow, thereby saving the volume and cost. A flow guide for noise reduction of the present invention is a flow guide installed inside a flow channel formed to allow air to flow from one side to the other side thereof, and comprises: a center part extending from one side to the other side thereof; and a guide part protruding from the outer circumference of the center part in the direction of diameter. The guide part extends along the longitudinal direction of the center part, and the other end of the guide part is formed at a position where same is rotated from one end of the guide part by a set angle. A device for reducing noise of the present invention comprises: the above-described flow guide; an upper case assembled on one end of the flow guide; and a lower case assembled on the other end of the flow guide, and a flow channel is formed by the upper case and the lower case.

The present invention relates to a household ventilation apparatus capable of adjusting air velocity in multiple stages and, particularly, to a household ventilation apparatus capable of adjusting air velocity in multiple stages, which is installed in a bathroom and the like of a building such as an apartment so as to adjust the ventilation speed and to change the ventilation speed such that noise is reduced or rapid ventilation is performed depending on a user's preference and the like. A household ventilation apparatus capable of adjusting air volume in multiple stages of the present invention comprises: a housing; a motor mounted in the housing; a fan member mounted on the motor so as to rotate; an air volume adjusting unit for setting the magnitude of the air volume of the fan member by means of external input; and a control unit for controlling the rotational speed of the motor in accordance with a set value of the air volume of the air volume adjusting unit. The control unit performs control such that, when the same air volume is set by the air volume adjusting unit, the rotational speed of the motor at a place having a high vent pressure is set to be higher than the rotational speed of the motor at a place having a low vent pressure.
