In such a ventilator, for the convenience of the user, the state quantity such as the outside air temperature, the room temperature, the humidity or the pollution degree of the room air is detected by various detecting means and is displayed by the displaying means. There is something. For example, regarding the outside air temperature, outside air temperature detecting means is provided near the outdoor side end of the air supply path for taking in outside air, and the outside air temperature based on the output detected by the outside air temperature detecting means is displayed by the display means. Has become.

That is, the outside air temperature detecting means continuously detects the temperature in the vicinity of the outdoor side end of the air supply passage of the ventilation device regardless of the operation stop of the ventilation device, and the outside air temperature is displayed by the display output formed based on this detection output. The display means operates to display. The outside air temperature displayed by the outside air temperature display means is associated with the detection value of the outside air temperature and soil detection means, and normally, as shown in FIG. 5, at the start of the ventilation operation, the temperature decreases below the display temperature up to that point. It will be.

FIG. 1 is a sectional view showing the structure of a ventilation device, and FIG. 2 is a circuit diagram showing the structure of an electric circuit. 3 is an explanatory diagram showing an example of a sampling and display algorithm of the state quantity, and FIG. 4 is an explanatory diagram showing an operation sequence and a display quantity of the state quantity display device. First, the ventilator will be described with reference to FIG. 1. This ventilator is a wall-mounted type that is mounted in a mounting opening formed in a wall 1 that separates the inside and the outside of a room. Two systems of air passages are formed: an exhaust passage 4 provided with an exhaust blower 3 for exhausting air to the outside of the room, and an air supply passage 6 provided with an air supply blower 5 for supplying outside air to the room. A grill 9 having a supply air outlet 7 and an exhaust suction port 8 is detachably mounted on the front surface of the main body outer casing 2 on the indoor side, and the supply air outlet 7 is provided at the end of the supply passage 6 of the main body outer casing 2. The exhaust suction port 8 is connected to the end of the exhaust passage 4 of the outer casing 2 in an independent state. The air supply passage 6 and the exhaust passage 4 are partially formed by the two working fluid passages of the heat exchanger 10 incorporated in the main body outer casing 2. The exhaust port 11 that is the outlet end of the exhaust passage 4 and the outside air intake 1 that is the inlet end of the air supply passage 6
2 are individually opened at the rear end of the main body outer casing 2 on the indoor side so as to face the outside. The grill 9 is provided with a display means 13 for notifying the user of the amount of state such as the room temperature, the humidity, the outside air temperature, and the pollution degree of the room air as ventilation operation information. The display means 13 displays the state quantity based on the detection output by the detection means provided in the air passage of the ventilation device. For example, with respect to the outside air temperature, the outside air temperature detecting means 1 mounted near the outside air intake 12 in the air supply passage 6
The outside air temperature detected by 4 is displayed. As for the electric circuit, for example, as shown in FIG. 2, a control circuit 15 including a microcomputer is connected to a motor 16 for driving the air supply blower 5 and the exhaust air blower 3, a display means 13, a detection means and the like. The control circuit 15 causes the forced ventilation operation for a constant interval, for example, about 5 minutes at an interval of 30 minutes regardless of the operating state of the ventilation device, and outputs the detection output from the detection means for, for example, 1 minute at the end of the forced ventilation operation. A value obtained by sampling and averaging this is displayed by the display means 13 (see FIG. 3). Even when the ventilator is not operating, the forced ventilation operation is performed by the sampling instruction, and the detection output from the detection means is sampled for, for example, 1 minute at the end of the forced ventilation operation, and the averaged value is stored. , Used as display output for the next 30 minutes.

者にとっては適切な換気情報が得られることになる。In the ventilator having the above-mentioned structure, as shown in FIG. 4, for example, the outside air temperature does not always correspond to the detected value of the outside air temperature detecting means 14, and the outside air temperature is displayed on the display means 13. That is, the display of the outside air temperature by the display means 13 is a value obtained by averaging the detection output from the outside air temperature detection means 14 for one minute at the end of the forced ventilation operation of about 5 minutes executed at 30 minute intervals. This value is
The detected value by the detection means after removing the disturbance element received by the structure of the ventilation system itself and the accessory parts at the place where the detection means for detecting the state quantity such as the outside air temperature and the room temperature is attached by the ventilation to prepare the detection environment Since it is based on this, accurate information can be obtained and appropriate ventilation information can be obtained for the user.

分あれば十分であるが、3〜4分程度でもよい。The interval of the forced ventilation operation for adjusting the detection environment may be about 1 hour, and the ventilation time is 5 hours.
It suffices if it is enough, but it may be about 3 to 4 minutes.
