And a filter 114 made of a metal such as a punched metal is provided so that the ventilation device can be washed and reused.

[0005]

In such a conventional ventilator, since the filter 114 is simply mounted on the suction grill 107, the oil contained in the contaminated air in the room due to the operation of the ventilator. When dust or the like adheres to the filter 114 and becomes clogged, the upper surface side of the filter 114 is in a negative pressure state, the filter 114 is sucked to the negative pressure side and moves upward, and is held by the spring 109, There is a problem that a part of the contaminated air sucked in from the suction grill 107 passes through the outside of the filter 114 and contacts the blower 104 in a state where the air is not purified, and the blower 104 is contaminated.

Further, when the operation is stopped, the negative pressure state on the upper surface side of the filter 114 disappears and the suction grill 10
The filter 114, which has risen above 7, is dropped on the suction grill 107 due to its own weight, and a metallic noise is generated. This causes a problem that the user feels that the filter 114 has failed and gives anxiety. there were.

An object of the present invention is to provide a ventilator that prevents the blower from being contaminated, and at the same time prevents the sound of the filter from falling and does not cause anxiety to the user. And

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is directed to an exhaust port connected to a duct communicating with the outside at the side or upper part in a box shape opened so that a suction port is formed on a lower surface. A main body provided with a blower therein and installed on a ceiling or the like, a suction grill provided to cover a lower surface of the main body, and a pair of spring stoppers provided on the main body, which are detachably attached to the suction grill. A spring in the form of a fork that elastically engages with
A spring mounting bracket formed by forming a curl portion to be embraced at the center portion, and a filter mounting bracket having an engagement groove engaged with the spring mounting bracket in a shape to be placed on the suction grill inner surface, A filter provided detachably, a laterally moving groove communicating with the engaging groove in the filter mounting bracket, and a projection elastically engaging with a curl portion of the spring mounting bracket when the filter is laterally moved. The filter is fixed via the filter mounting bracket even if oil dust in contaminated air adheres to the filter during operation and clogging occurs and the upper surface of the filter is under negative pressure. This prevents the filter from lifting up on the suction grill and contaminated air passing outside of the filter, thus preventing the blower from becoming contaminated. Luther prevents that falls onto the suction grille, an effect that it is unnecessary to give anxiety to occur is prevented users of metallic sound due to dropping of the filter.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIGS. (Embodiment 1) As shown in FIGS. 1 to 5, a box-shaped opening having a suction port 1 formed on a lower surface thereof has an exhaust port 3 connected to a duct 2 communicating with the outside on the side. A pair of spring stoppers provided on the main body 5 are provided on a main body 5 provided with a blower 4 for sucking air from the suction port 1 and exhausting air from the exhaust port 3 and a suction grill 6 provided to cover the lower surface of the main body 5.
