Abstract

PROBLEM TO BE SOLVED: To provide a house where the harmful compounds which adversely affect the human bealth are detected and a warning is given to the dwellers against a high airtight structure of the house. SOLUTION: A sensor 10 and a warning device 11 are placed at least a part of a high airtight house A. Thus, the sensor 10 detects the harmful chemical materials contained in the air are detected and the device 11 outputs a warning based on the signal received from the sensor 10. As a result, the warning is quickly given to the dwellers of the house A when a harmful chemical material contained in the air exceeds fixed level. Then ventilation is urged and a necessary level of ventilation is shown. Thus, it's possible to consider the health of dwellers of the house A while saving the house energy.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a highly airtight house.
The present invention relates to a house that can detect harmful compounds that have an adverse effect on the human body, such as formaldehyde, VOC, pesticide-based preservatives, insect repellents, and termite pesticides contained in the air, and can promptly warn and alert residents.

[0002]

2. Description of the Related Art At present, when energy saving is called for, an airtight layer and a heat insulating layer are arranged on an outer wall and a roof, an opening is made of aluminum or resin, and a sash made of glass is used. Insulated and airtight houses are becoming common, and energy-saving houses with low heat loss rates are becoming more common.
When a house with high heat insulation and high airtightness is used as described above, the outside air and the inside air inside the house are shut off by the airtight layer, so that ventilation between the outside air and the inside air must be performed systematically. However, only insulation and air-tightness were considered important, and unbalanced houses were being constructed without regard to ventilation.

[0003]

Under these circumstances, indoor air pollution in houses has become a social problem in recent years. That is, various adhesives used for building components of houses, preservatives pretreated on wood,
Hazardous compounds released over time from insect repellents, termite repellents, etc. stagnate in the airtight indoor air, leaving the resident's brain, nervous system, respiratory system, and immune system without ventilation. The problem of causing damage has arisen.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a sensor for detecting a harmful chemical substance contained in air at least at one place in a house, and a warning by a signal from the sensor. By providing a house equipped with a warning alarm device that gives an alarm, when harmful chemical substances in the air exceed a certain value, the resident is immediately warned and alerted to that effect, urges ventilation and encourages ventilation. Teaches the standard of a good ventilation,
It proposes a house that considers the health of residents while maintaining energy saving.
