Abstract

PURPOSE:To maintain the inside of the device in a state that dew condensation does not occur by measuring atmospheric pressure which is scarcely influenced by the land form by an atmospheric pressure sensor and predicting the weather, and operating a dehumidifying device, based on its result. CONSTITUTION:In the lower part of a box body 2, and the upper part, space heaters 4a, 4b, and an atmospheric sensor 19 are provided, respectively, and at the time of operating a heater, power is supplied from a space heater control power source 16 by closing manually a section breaker 17. An output of the sensor 19 is converted to a digital value by an atmospheric pressure A/D converting circuit 21, and corrected to sea surface atmospheric pressure by using a sea surface correcting circuit 22. Also, the atmospheric pressure upper limit reference value and the lower limit reference value set in advance are compared by a first weather deciding circuit 23, and when the value exceeds the upper limit, it is decided to be fine weather, and unless it satisfies the lower limit, it is decided to be rainy weather. Moreover, in a second weather deciding circuit 25, when a differential value of a differentiating circuit 24 is positive, it is decided that atmospheric pressure rises and the weather becomes better, and when the differential value is negative, it is decided to become rainy weather. Simultaneously, humidity converted by a humidity A/D converting circuit 28 is compared with reference humidity determined by a humidity deciding circuit 31, and the heater is controlled thereby.

2), the pressure is corrected to sea level, and the first weather judgment circuit (
23) is compared with the preset upper limit reference value (b) and lower limit reference value (C), and the upper limit reference value (C) is determined.
When the lower limit of atmospheric pressure (C) is exceeded, the weather is determined to be clear, and when the lower limit reference value (C) of atmospheric pressure is not met, the weather is determined to be rainy. For example, at point F, the atmospheric pressure upper limit standard 1 (b) is exceeded, so the weather judgment is clear. At point D, the atmospheric pressure lower limit reference value (C) is not satisfied, so the weather is determined to be rainy. That is, the atmospheric pressure upper limit reference value (b) is a value that determines the weather to be sunny, and the atmospheric pressure lower limit reference value (C) is a value that determines the weather to be rainy. Atmospheric pressure upper limit reference value (b) and atmospheric pressure lower limit reference value (
The atmospheric pressure during C1 is differentiated by a differentiation circuit (24), and the amount of change in atmospheric pressure per predetermined time is also determined. The second weather judgment circuit (25) operates when the differential value of the differential circuit (24) is positive.
The atmospheric pressure is rising and the weather is improving, so the weather judgment is clear skies. On the other hand, when the differential value is negative, the atmospheric pressure is decreasing and the weather is worsening, so the weather judgment is rainy. For example, at point E, the differential value becomes positive and the weather judgment is clear. At point G, the differential value becomes negative and the weather judgment is rainy.
