Abstract

An air supply hood that eliminates various risks due to insufficient air supply in winter and is easy to install. An air supply hood 1 incorporating a heater 2 and a thermo switch 3 is installed on an external wall surface at the top of the ceiling, and the outside air controlled by the heater and the thermo switch is taken into the ceiling, and is supplied from an indoor air supply port. It is a structure that supplies air, and is useful as a measure against drafts and internal condensation, and as a countermeasure against sick house. Furthermore, it can be easily installed by integrating the hood, heater and thermo switch. [Selection] Figure 1

Description

The present invention relates to an air supply hood that can be easily attached by heating the outside air temperature inside the main body.

The 2003 amendment to the Building Standards Law mandates 24-hour ventilation. In order to exhaust the air by always operating the ventilation fan, it is necessary to take in a corresponding amount of fresh air.

For the purpose of providing sufficient ventilation and preventing sick house, 24 hour ventilation is indispensable.

However, in kitchens and kitchens, a fan with a large air flow or a fan with consideration for oil smoke and moisture is required. The air supply is natural, and the third type ventilation is forcibly exhausted using an exhaust fan. However, sufficient ventilation cannot be achieved unless a supply amount equal to the exhaust amount is taken in.只 In winter, the supply air may be closed to dislike the intrusion of cold air, and the supply air does not enter, so the exhaust efficiency is lowered and the indoor air may be stagnant. Furthermore, when the outside air temperature is low and the room temperature is high, condensation may occur on the surface or inside of the main body. In order to eliminate the difference from the outside air temperature, there is a configuration in which a heater is provided in the outside air intake electric shutter and the heater is energized when the outside air intake electric shutter is opened.

The problem to be solved is to easily solve various risks due to lack of air supply in winter.

The present invention is characterized in that a heater 2 and a thermo switch 3 are built in an air supply hood 1 corresponding to an outside air intake, and a problem caused by insufficient air supply is solved only by mounting the air supply hood 1.

In the present invention, an air supply hood 1 including a heater 2 and a thermo switch 3 is installed on an external wall surface at the top of the ceiling, and air is supplied into the room from the ceiling through an indoor air supply port. The outside air controlled to an appropriate temperature by the heater 2 and the thermo switch 3 is taken in, and it serves as one of the countermeasures for drafts due to insufficient supply, internal condensation prevention, and sick house measures. Furthermore, since the air supply hood 1, the heater 2, and the thermo switch 3 are integrated, a means for heating the outside air is easy, and the body receiving plate 8 of the air supply hood 1 integrated with the opening of the wall surface is combined, Just install it to make an effect.
