Description

[Detailed description of the invention] This invention relates to the improvement of a range ventilation fan that has a blower built into the body of a range hood that covers the top of a gas range, etc. in a kitchen. When the installation width dimension of the main body is regulated and the installation work of the exhaust duct to the range hood main body becomes a later construction work, it is possible to make the installation work of the exhaust duct easy and to connect the exhaust duct and the range hood main body. The purpose of the present invention is to provide a ventilation fan for a microwave oven which prevents the appearance of interior parts from deteriorating and improves ventilation efficiency.

Conventional range ventilation fans of this type first install only the range hood body with the internal motor and fan removed at a predetermined position on the wall of the kitchen above the gas range, etc., and then either one of the range hood bodies is installed. The other end of the exhaust duct, which passes through the wall inside the kitchen and communicates with the outdoors, is connected to the exhaust port formed on the side or back side via a flange, and the motor and fan are housed inside the range hood body. However, since the decorative plate that supports the motor and fan and forms the exhaust passage must be attached to a predetermined position on the range hood body, the assembly process is extremely troublesome and difficult to work with. The problem was that the connection point with the hood itself spoiled the aesthetics of the interior.

This idea was made with attention to these points, and it is extremely easy to assemble, and the connecting point between the exhaust duct and the range hood body does not spoil the aesthetics of the interior, and it also creates a fresh exterior. The purpose of the present invention is to provide a ventilation fan for a range that supplies air into a room and improves ventilation efficiency.

That is, Figs. 1 to 5 all show one embodiment of this invention, and in Figs. 1 to 3, 1 is the ceiling in the kitchen K, 2 is the wall of the kitchen K, and 3 is the kitchen. A hanging cabinet is hung at a predetermined position on the ceiling 1 of , 15 is an exhaust chamber formed at a predetermined position on the upper surface of this range hood main body 5, and a tapered duct connection frame 17 provided at a rear opening 16 of this exhaust chamber 15.
The inner end of an exhaust duct 4 whose free end passes through the wall 2 and communicates with the outside is fitted and connected to the exhaust duct 4 . Reference numeral 22 is removably attached to a predetermined position on the upper surface of the range hood main body 5 with a plurality of mounting screws 19 so as to cover the exhaust chamber 15 from the front thereof, and has a slit-shaped air supply hole 21 on the front surface.
A tapered duct connection frame 25 provided at a predetermined position on the back side of the air supply chamber 22 has a free end communicating with the outside through the wall 2. air supply duct 24
The inner ends of the two are connected by fitting. A plurality of air intake ports 23 are bored on the other back surface and both sides of the air supply chamber 22, and the other air intake ports 23 that are not connected to the air supply duct 24 are as follows.
As shown in FIGS. 3 and 5, a blind lid 23a is provided that can be opened and closed selectively.

Next, in the longitudinal cross-sectional view shown in FIG. 4 and the perspective view shown in FIG. A motor 7 is attached to the rear wall via a mounting base 6, and a centrifugal fan 8 is attached to the rotating shaft of the motor 7 with a nut 9. The air supply port 11 faces the rotational center on the suction side of the centrifugal fan 8, and the exhaust port 12 faces a predetermined position on the outer periphery of the centrifugal fan 8 on the discharge side. It is configured. 14 is a filter that covers the suction port 13 formed at the lower part of the range hood main body 5, and when the range hood main body 5 is installed on the wall 2 in the kitchen K, this filter 1 is
The range hood main body 5 is attached to the suction port 13 from which the cooker 4 has been removed using predetermined wood screws or the like. Further, the work of connecting the exhaust duct 4 and the air supply duct 24 to the exhaust chamber 15 and the air supply chamber 22 is performed after the range hood main body 5 is attached to the wall 2 in the manner described above. This is done by utilizing the space between the upper surface and the ceiling 1, and the inner ends of the exhaust duct 4 and the air supply duct 24 are connected to the exhaust chamber 15 and the air supply chamber 2.
Tapered duct connection frame 17 provided on the back of 2
and 25 are connected by fitting.

As described above, according to this invention, the exhaust duct 4 and the exhaust chamber 15 discharge indoor air to the outside by the fan 8 in the range hood main body 5.
Adjacent to this is air supply chamber 2, which also serves as a cosmetic case.
Since the connection point between the exhaust duct 4 and the exhaust chamber 15 of the range hood body 5 is hidden from the front by the air supply chamber 22, not only will the connection point between the exhaust duct 4 and the exhaust chamber 15 of the range hood body 5 not spoil the aesthetics of the indoor interior, but also This allows fresh outside air to be supplied indoors, which has the effect of significantly improving ventilation efficiency. Further, according to this invention, the connection between the exhaust duct 4 and the air supply duct 24 and the exhaust chamber 15 and the air supply chamber 22 is achieved by using tapered duct connection frames 17 and 25 provided in both chambers.
Since the connection is made through the connection, it has the effect that the connection work is extremely simple and quick compared to the conventional method.
