DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0002]

2. Description of the Related Art In order to design a house having an excellent thermal environment in consideration of comfort and energy saving, it is important to understand the external weather conditions of a planned construction site. When designing such a thermal environment, the standard weather data of the nearest city is often used.However, since the number of cities with standard weather data is limited, such cities exist nearby. Otherwise, it is impossible to use standard weather data.

[0003] For this reason, the actual condition is that the weather conditions are determined by using an automatic observation data (AMeDAS data) of the Meteorological Agency having a relatively large number of observation points and by approximation by linear interpolation between adjacent observation points. is there. However, the weather conditions
Even near the observation point of the automatic observation data, it changes considerably depending on the topography, altitude, and the like. For example, at a point at a distance of about 6 km from the observation point and an elevation difference of 50 m, a temperature difference of about 1 to 3 ° C. occurs with the observation point, and at a point at a distance of about 30 km from the observation point and an elevation difference of 335 m, It is known that a maximum temperature difference of about 6 ° C. occurs with the observation point.

[0004] Accordingly, in order to accurately grasp the weather conditions of the planned construction site, the temperature and temperature must be measured at as many points as possible.
It is necessary to collect weather data such as humidity. Conventionally, such data such as temperature and humidity is collected using, for example, a hundred-leaf box.

[0005]

However, when a hundred-leaf box is used, the installation space tends to be large, and heat tends to be trapped in a state of receiving sunlight.
There is a problem that the temperature rises in the multi-leaf box, the measured temperature becomes higher than the actual outside air temperature, and an error occurs.

[0006]

Further, in a state where there is sunlight, the fan 11 is driven to rotate by the solar cell panel 15, and air flows from the lower side to the upper side in the inner cylinder 7 and the outer cylinder 8, so that the ambient temperature of the sensor 9 is outside air temperature. And the temperature measured by the sensor 9 becomes accurate.

That is, when the fan 11 rotates, air flows in from the lower end of the inner cylinder 7 as shown by the arrow A in FIG. From the gap 35 (see FIG. 6) through the space inside the cylindrical member 12 to the back surface (lower surface) of the flat upper bottom portion of the reflector 13 and collides with the back surface to change its direction.

For example, when the outside temperature and humidity measurement device 1 is installed in a place where popularity is low, only the main body 2 is installed at the observation position, while the recording device 3 is installed.
May be installed in an easily accessible place such as near a building, and the main body 2 may wirelessly transmit measurement data to the recording device 3. In the above embodiment, the recording device 3 is the main body 2
Although the main unit 2 and the recording device 3 can be integrally configured, they are configured as separate units.

[0026]

According to the first aspect of the present invention, there is provided an outside air temperature / humidity measuring device, comprising: a sensor for detecting temperature and humidity; an inner cylinder and an outer cylinder which double surround the periphery of the sensor; Since it is provided with a hat-shaped reflector provided at the upper part of the cylinder, even if the solar radiation hits the outer cylinder and thereby the temperature of the outer cylinder rises, furthermore, there is a further gap between the outer cylinder and the sensor. Since the inner cylinder is located, the problem that the heat of the outer cylinder directly acts on the sensor and the temperature measured by the sensor becomes higher than the actual outside air temperature is less likely to occur. In addition, since the shade-shaped reflection plate is provided on the upper portion of the inner cylinder, there is an advantage that the heat measurement from the sensor is accurately performed without the solar heat from the upper portion acting on the sensor. The reflection plate, the inner cylinder, and the outer cylinder also play a role of preventing rain from entering the inner cylinder (sensor position) and a role of preventing heat radiation.

According to a second aspect of the present invention, in the configuration of the first aspect, since a fan for circulating air in the inner cylinder and the outer cylinder is provided in the configuration of the first aspect, the fan discharges air. As a result, air constantly flows in the inner cylinder and the outer cylinder, so that heat due to solar radiation does not accumulate in the inner cylinder and the outer cylinder, and the temperature measurement by the sensor is performed more accurately.

According to a third aspect of the present invention, there is provided an external temperature and humidity measuring apparatus according to the second aspect of the present invention, wherein a solar cell for driving the fan is provided. There is no need to connect to the power supply, and advantages such as simplification of the configuration and reduction of the power cost are obtained. In a state where there is no sunlight such as at night, the solar cell is not charged and the fan is not driven.However, in a state where there is no sunlight, heat is not originally stored in the outer cylinder and the inner cylinder. There is little need to drive it, and it is sufficient if the fan is driven only when there is solar radiation.

According to a fourth aspect of the present invention, there is provided an external temperature and humidity measuring apparatus according to any one of the first to third aspects, wherein a recording device for recording the temperature and the humidity detected by the sensor is provided as a separate unit. Therefore, by recording the temperature and humidity data continuously or intermittently (periodically) by this recording device, it is possible to use the data for the thermal design when building a house.

According to a fifth aspect of the present invention, in the configuration of the fourth aspect, since the signal indicating the temperature and the humidity detected by the sensor is transmitted to the recording device wirelessly, for example, When installing the outside temperature and humidity measuring device in a place that is less popular, away from buildings such as houses, install only a recording device separately from the measuring device near the building such as a house and measure the data from the measuring device. Is transmitted wirelessly to the recording device, whereby there is an advantage that measurement data can be easily collected.

According to a sixth aspect of the present invention, there is provided an outside temperature and humidity measuring apparatus according to any one of the first to third aspects, wherein a recording device for recording the temperature and humidity detected by the sensor is provided integrally. Since the entire apparatus is integrated, advantages such as easy handling are obtained.
