Description of the Related Art When a ventilator is installed, it is necessary to perform a ventilation test to measure the amount of ventilation by the ventilator while the ventilator is installed in order to check whether a predetermined amount of ventilation is obtained. There is. The measurement of the ventilation volume, for example,
The measurement is performed by measuring the wind speed of the ventilation air or by measuring the air volume of the ventilation air. As described above, examples of the ventilation amount detecting means for detecting the ventilation amount include an anemometer and an anemometer.

[0003] Conventionally, the ventilation amount inspection is performed by measuring the air flow or the wind speed in front of the suction unit to measure the ventilation amount. In this case, since it is necessary to define the flow range of the air to be ventilated, a cylindrical body for inspection is arranged in front of the suction part so as to surround the entire periphery of the opening, and the inspection part for the inspection is provided. This has been done by arranging the detection unit of the ventilation amount detection means inside the cylindrical body. Alternatively, the detection unit of the ventilation amount detecting means is disposed in front of the exit of the ventilation air passage.

[0004]

However, conventionally, when a ventilation volume test is performed by arranging a tubular body for inspection in front of the suction unit, the tubular body for inspection is placed at a place where the ventilator is installed. In addition to bringing it, it is necessary to appropriately arrange a cylindrical body for the inspection at a predetermined position, and it is troublesome, and thus an improvement has been desired. In addition, when the ventilation volume inspection is performed in front of the exit of the ventilation air passage, depending on the installation location of the ventilation device such as a high-rise house, the outdoor exit of the ventilation air passage will be located at a high place, In some cases, ventilation volume tests could not be performed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to perform a ventilation amount inspection in a state where a ventilation device is installed simply and at the position of an outlet of a ventilation air passage to the outside. The point is to be able to do it.

According to the fourth aspect of the present invention, the air in the room to be ventilated sucked from the suction portion flows through the circulation air passage and the ventilation air passage and is discharged by the ventilation action of the ventilation blower. The room to be ventilated is ventilated. In addition, the ventilation target room can be heated by circulating the air in the ventilation target room by the heating means while circulating the air in the ventilation target room through the circulation air passage. In addition, while circulating the air in the room to be ventilated through the circulation air passage, in parallel with heating the ventilation air in the circulation air passage by the heating means, a part of the ventilation air in the circulation air passage is removed by the ventilation blower. The ventilation target room can be dried by ventilating and discharging the ventilation air passage. In other words, the suction unit for sucking the air in the room to be ventilated to circulate the air in the room to be ventilated and the suction port to suck the air in the room to be ventilated to ventilate the room to be ventilated are also used. Thus, the configuration is simplified. Therefore, according to the characteristic configuration of the fourth aspect, in implementing the present invention in a ventilator having a function of heating and drying in addition to the function of ventilating the room to be ventilated, the implementation cost can be reduced. .
