BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a kitchen air supply device for supplying the outdoor air into the kitchen when the kitchen is ventilated during heating and cooking.

[0002]

2. Description of the Related Art Generally,
In the kitchen, an exhaust device such as a range hood is provided above a heating table having a heating device such as a gas stove, and the air in the kitchen is exhausted to the outside while heating and cooking. However, if the structure is such that the air in the kitchen is only exhausted by the exhaust device, when the exhaust device is driven to ventilate, the air supply necessary for the exhaust is also passed to other rooms such as the living room. Retracted,
In addition to exhausting a large amount of air-conditioned air in the living room and the like, which impairs the air-conditioning effect, there is a problem in recent years in highly airtight homes that the negative pressure in the room also increases because air is drawn from a small gap.

In recent years, a range hood having a supply / exhaust function has been provided so that both supply and exhaust can be performed.
This is to exhaust the air in the kitchen to the outside through the exhaust path of the range hood and to supply the outside air into the kitchen through the air supply path of the range hood, reducing the amount of air drawn from other rooms. Although the air conditioning effect of the living room, etc. can be maintained, air is supplied from a small area, so the blowing speed becomes faster, and the air turbulence disturbs the collection rate of air to be exhausted in the range hood, and the temperature environment of the kitchen itself. However, there is a problem that the improvement effect of the above is small.

As another conventional example, Japanese Patent Laid-Open No. 2001-21
5035, JP-A-11-132519, JP-A5-1
Although the one disclosed in No. 80483 is also provided, it has the following problems.

The device disclosed in Japanese Unexamined Patent Publication No. 2001-215035 provides a space between the wall surface of the kitchen and the hanging cabinet, and blows out the outdoor air from the entire space so as to gently supply air into the kitchen room. It has become. However, in order to provide an air supply port over a wide area as described above, there is a gap between the wall of the kitchen and the back of the hanging cabinet, or a gap between the ceiling and the top of the hanging cabinet. There is a problem that the internal volume of the kitchen or the hanging cabinet becomes smaller.

The one disclosed in Japanese Unexamined Patent Publication No. 11-132519 has an air supply box provided between the range hood and the hanging cabinet when the hanging cabinet or the range hood is provided along the wall surface of the kitchen. Outdoor air is blown into the kitchen from the bottom to supply air. With such a device, air can be supplied from the vicinity of the range hood, but there is a problem that the storage capacity of the hanging cabinet becomes small because the air supply box is originally provided in the place where the hanging cabinet is originally provided.

In the one disclosed in Japanese Patent Laid-Open No. 5-180483, an air supply box is provided on the outer periphery of the range hood so as to be integrated with the range hood, and air can be supplied and exhausted at the same time. In such a case, the amount of conditioned air discharged from the range hood is suppressed even when air-conditioned in the kitchen, but it is difficult to take a large air supply area because it is integrated with the range hood. Similarly, the storage capacity of the hanging cabinet is sacrificed.

The present invention has been made in view of the above points, and a wide air supply blowout area can be obtained without narrowing the storage capacity of the hanging cabinet, and the air supply speed can be reduced to exhaust the air by the wind. An object of the present invention is to provide a kitchen air supply device that can reduce negative pressure while suppressing adverse effects on the collection rate of air that should be collected.
