Description

[Detailed Description of the Invention] The present invention relates to a retractable ventilation hood, and particularly to improvements in its side ventilation structure.

Conventionally used ventilation hoods are disposed directly above gas appliances, for example, so they have a ventilation opening that opens at the bottom. Therefore, the ventilation area is fixed, and any hot air that exceeds the ventilation capacity even slightly will escape from the surrounding area to the ceiling.

Therefore, in recent years, ventilation hoods have come to be used that include a movable hood portion, which is formed by a rotatable door on one side of the hood body and a side plate that slides into contact with the hood body. According to this kind of hood, by opening the movable hood part, the ventilation capacity can be increased compared to the conventional one. In addition, since the ventilation hood is usually arranged side by side with the hanging cupboard in the kitchen room, the movable hood part is rotated to the front side (front side) to be in the open state.

However, even with this type of structure, there is a limit to the amount of opening, so a certain amount of hot air is not captured and accumulates near the ceiling. Also, hot air tends to accumulate near the ceiling due to hot air from another heat source or ambient temperature. When the movable hood section is opened, the side plates thereof extend from both side surfaces of the hood body, and instead become a hindrance to ventilating hot air near the ceiling.

The present invention was developed in view of the above circumstances, and its purpose is to provide a ventilation hood that has a relatively simple structure but can increase ventilation capacity when the movable hood part is open. This is what I am trying to do.

An embodiment of the present invention will be described below based on the drawings. 1 in the figure is the hood body. This hood main body 1 has all metal plates formed into a box shape, and the front and bottom surfaces are open. A duct 3 that accommodates a ventilation blower 2 inside is provided protruding from the back side and fits into a hole b provided in an attached wall a. The opening on the bottom side is formed as a ventilation port 4, and the opening 5 on the front side is opened and closed by a movable hood part 6, which will be described later.

This movable hood part 6 consists of a door body 7a and a movable hood body 7 to which the door body 7a is attached and which has side plates 8, 8, and the upper end thereof is rotatable to the hood body 1 via a hinge 9. It is pivoted to. To explain, the door body 7a is, for example, what is called a particle board, and the opening 5 is
It has an area that closes the area. It will look good if you select one with the same color or pattern as the hanging cabinets (not shown) installed on both sides of the ventilation hood. The side plates 8, 8 are each made of a metal plate formed into a substantially triangular shape, and one side edge thereof protrudes rearward from the movable hood main body 7 on the back surface of the door body 7a. Moreover, it is provided at a position very close to the side surface of the hood main body 1. At the top of each of these side plates 8, 8, there is a triangular auxiliary ventilation opening 1 that is approximately similar to the side plates 8, 8.
0 and 10 are open. As shown in Figure 4, the door body 7
The auxiliary ventilation ports 10, 10 must be provided so that they completely protrude from the hood body 1 when the hood a is rotated. Note that one side plate 8 and the hood main body 1 are connected by a stay (not shown), and when the door body 7a is rotated to open the opening 5, this state can be maintained reliably. Further, if the door body 7a is pulled toward the front side from this state, the fixed state of the stay is released, and the door body 7a can close the opening 5.

By driving the ventilation blower 2, ventilation with the outside can be achieved through the ventilation opening 4 and the duct 3.
If the door body 7a is rotated to open the opening 5 as necessary, the ventilation area can be expanded and effective ventilation can be performed. At this time, the auxiliary ventilation ports 10, 10 protrude from the hood body 1. That is, auxiliary ventilation ports 10, 10
is opened, allowing ventilation to escape through the enlarged ventilation opening 4 or to efficiently draw in hot air accumulated near the ceiling c from the side.

In the above embodiment, the auxiliary ventilation ports 10, 1
Although 0 is assumed to be triangular, the shape is of course not limited.

Further, although the door body 7a and the side plates 8, 8 are constructed as separate parts, they may be integrated.

As explained above, according to the present invention, in a hood that is composed of a hood main body having a ventilation port and a movable hood part that expands the ventilation area by providing a side plate on the door body, the door body can be opened on the side plate. Because we installed an auxiliary ventilation opening to ventilate from the side when
It can efficiently ventilate hot air that escapes from the ventilation openings or accumulates near the ceiling, has a very simple structure, and has a great practical effect in that it can improve ventilation capacity without having a negative impact on cost.
