Description

  The present invention relates to a range hood that is installed above a cooking appliance in a kitchen, sucks and captures oil smoke, odor, steam and the like generated during cooking and exhausts it outdoors or indoors. More specifically, the cooking appliance is installed. The air collected and sucked in the kitchen with a simultaneous supply / exhaust range hood that supplies outside air at the same time as the exhaust, and a kitchen equipped with a heating cooker such as an electromagnetic cooker or electric stove is again exhausted into the room It relates to an indoor circulation type range hood.

Conventionally, general range hoods are installed above cooking utensils (for example, gas ranges) in kitchens, and are used to efficiently capture oily smoke, odors, and steam generated by cooking and exhaust them efficiently outdoors. Has been.
However, in recent years, as a result of energy savings or the rise of high-rise apartments due to the increase in high-rise apartments, the room including the kitchen became negative due to the exhaust operation of the range hood. In addition to causing problems, it has become a factor that creates an unpleasant environment for the user, such as difficulty in opening and closing the door, or air flowing through a narrow gap in the door or the like to generate a beeping sound.

  Therefore, a simultaneous supply / exhaust range hood has been installed in buildings where an increase in negative pressure in the room becomes a problem. This simultaneous supply / exhaust range hood opens an air supply opening to a curtain plate provided at the top of the hood body in order to conceal the exhaust duct and blower connected to the range hood from the user's view. An air supply duct that communicates with the outdoors via an air supply duct connection path is connected to the mouth, whereby fresh outdoor air is supplied to the room (see, for example, Patent Document 1).

  The simultaneous supply / exhaust type range hood has the above-described configuration, with a natural supply type that is naturally supplied by the negative pressure generated by the exhaust operation of the range hood, and the supply duct connection path. There are two types of forced air supply types in which an air supply blower is provided as an auxiliary, and natural air supply by negative pressure and air supply by operation of the air supply blower are provided.

The air supply opening provided on the curtain of the above-mentioned simultaneous supply / exhaust range hood gives an uncomfortable feeling to the user standing in front of the cooking utensil when the air supply directly hits it. The air supply port is provided on the upper side of the curtain so as not to hit.
In addition, if the supplied outside air directly contacts the ceiling or the like, the ceiling portion will become dirty.To prevent this, the air supply port is equipped with a wind direction plate or louver, and the direction of the outside air blown from the air supply port Can be adjusted vertically.

By the way, the installation location of the range hood A ′ in the kitchen has a wall on either the left or right side as shown in FIG. In many cases, there is a wall that divides the kitchen on the back side.
On the other hand, when the exhaust amount of the range hood is large, the supply air flow blown out from the supply port 17 also increases the supply air amount.

The air flow blown into the room at a high speed collides with the front wall as it is.The collided air flow spreads into the partitioned kitchen, and at the same time, the air flow inside the kitchen is greatly disturbed. It does not rise smoothly and has a problem that it cannot be sufficiently captured by the range hood.
In particular, in the case of an electromagnetic heating cooker that has spread rapidly in recent years, an updraft caused by heating is not generated, and thus the airflow is further disturbed.
In addition, a part of the air flow that collides with the wall bounces off, and sometimes hits the back from the user's head, which causes a problem of discomfort to the user.
Recently, in the current situation of high airtightness, high thermal insulation, and high-rise buildings, there are various problems with the conventional range hood that exhausts the air captured and sucked outdoors (for example, changes in indoor air pressure, Contamination, energy loss, etc.) are no longer occurring, and indoor circulation range hoods are being developed as alternatives.
The indoor circulation type range hood can solve the above-mentioned problems, but the exhaust flow (air supply) blown into the room has the same problem as the above-described simultaneous supply / discharge range hood.
