Abstract

PURPOSE:To change automatically an alarm set time on a rainy day by providing an alarm set time changing circuit which is operated by an output of a rainfall sensor. CONSTITUTION:An output of a rainfall sensor 1 is converted to a digital signal by a processing circuit 2, and inputted to an alarm set time changing circuit 3. An alarm setting part 4 can set the time of two kinds of a fine weather use set time and a rainy weather use set time, and the alarm set time changing circuit 3 switches both the set time in accordance with a signal from the rainfall sensor 1, and an alarm sound generating circuit 6 generates an alarm sound by a loudspeaker 7. In this way, a change scheduled time can be set in advance, therefore, a quiet sleep can be executed without minding the weather.

Description

[Detailed description of the invention] [Technical field] The present invention relates to an alarm clock.

[Background technology] In general, it is often necessary to change one's activity schedule depending on the next day's weather. For example, if the commuting time is longer on a rainy day than on a normal day, it is necessary to change one's schedule on a day when it is likely to rain. It is necessary to set the alarm setting time early. However, with conventional alarm clocks, there was a problem with people forgetting to set it early, or sometimes it wasn't raining even after midnight, making it impossible to get a restful night's sleep.

[Object of the Invention] The present invention has been made in view of the above problems, and its purpose is to provide an alarm clock whose alarm setting time is automatically changed on rainy days. be.

[Disclosure 1 of the Invention The alarm clock of the present invention is characterized in that it includes a rain sensor that detects rain and an alarm setting time changing circuit that is activated by the output of the rain sensor. When changing the time, read the status of the rain sensor at the scheduled change time, and if it is raining, change the set time and immediately generate an alarm sound, and if it is not raining, do not change the set time. In addition, when changing the time later, if it is raining at set a or 'y time, the set time is changed, and if it is not raining, an alarm sound is generated.

FIG. 1 shows an embodiment of the circuit of the present invention. In the same figure, a rain sensor 1 is installed outdoors, and for example, raindrops are held between electrodes by capillary action to detect changes in immunity between the electrodes.The output of this rain sensor 1 is is converted into a gage digital signal by the processing circuit 2 and inputted to the alarm setting time changing circuit 3. The alarm setting section 4 is capable of setting two different times, a set time for clear weather and a set time for rainy weather, and the alarm setting time changing circuit 3 is configured to switch the preset time in response to a signal from the rain sensor 1. It has become. The configurations of the clock circuit 5 and the alarm sound generation circuit 6 are the same as those of the prior art.

The embodiment shown in FIG. 2 is an application of the present invention to a lifestyle information board. In the figure, A is the main body of the lifestyle information board, including a speaker 7, an intercom handset 8, an indicator lamp 9, a visitor notification set switch 10, and a rain notification t! ! Life information signboard boss equipped with a single-function set switch 11, a manual nameplate light off switch 12, an alarm sound stop button 13, a clock part 14, a space 15 with a built-in time setting switch, a nameplate light 16, a doorbell 17, a mailbox 18, etc. )B, a bath sensor C1, an additional alarm speaker D having an alarm sound stop button 19, etc. are provided as a terminal device. The speaker 7 of the information board body A is used to generate various notification sounds in addition to the alarm sound, and the additional speaker D is installed in the bedroom. On the lifestyle information board body A above,
It has a built-in circuit shown by the broken line in Fig. 1, and a rain sensor 1 is installed on the top surface of the living information sign boss (B).According to this NIT precept, using the outdoor living information sign boss (B), The rain sensor 1 can be installed on the WR desk.

[Effects of the Invention] As described above, the alarm clock of the present invention detects rain and automatically changes the alarm setting time.
If you have to leave early in case of rain, or if you have to cancel your departure if it rains, you can set a new scheduled time in advance, so you can get a good night's sleep without worrying about the weather. There are advantages.
