  The automatic driving prior notification means 14 is incorporated in the remote control device 10 and informs the user that the automatic driving is started for a certain time before the start of the automatic driving by voice, buzzer, LED lighting, flashing, etc. Inform.

  The overall flow of processing by the operation assumption means 11 will be described with reference to FIG. As shown in FIG. 4, statistical data is acquired, and driving assumption processing is performed to predict automatic driving from the acquired data when automatic driving is enabled. In step S001, the hourly data described above in the history information example of FIG. 2 is acquired as statistical data. In step S002, when automatic operation is enabled by the automatic operation setting switch 10j, an operation assumption process in step S003 is performed.

  Next, the driving assumption process will be described with reference to FIG. As shown in FIG. 5, in step S004, if the ratio of the driving mode of the driving estimation result assumed by weighting the statistical data on a daily basis and taking the statistics is 60% or more, it is determined as the life pattern of the user. Then, it is recognized that it matches the user's intention, and the automatic driving process in step S005 is performed. When the ratio of the operation mode of the operation assumed result is less than 60%, it is determined that there is no regularity and the automatic operation process is not performed.

Therefore, if it matches the user's intention, it can be stopped before starting automatic operation or it can be switched to another operation if it is different. Or not understand in advance of, it is possible to correspond the executability, there can be provided an advantage of operation consistent with the user's intention is carried out.

  In addition, the driving assumption means obtains history information in units of one hour, takes statistics by weighting in units of one day, predicts optimum driving, and when driving mode statistics fall below a predetermined ratio Since the automatic operation is not performed, if the statistics do not reach a predetermined ratio, it is highly likely that the user's intention does not match. It is possible to obtain an effect that there is a high possibility of matching.

  Further, when the home detection means detects the absence of the user and the operation mode is a specific operation mode, the automatic operation is performed. Since it can respond to the case where it wants to drive, the effect that the driving | running | working according to a user's intention can be performed can be acquired.

  In addition, when the home detection means detects that the user is absent, the automatic operation is performed when the user is in a specific season and operation mode, so that the user is absent such as preheating in winter, for example. However, since it is possible to cope with the case where it is desired to drive automatically, it is possible to obtain the effect that the driving in accordance with the intention of the user is performed.

  Further, the operation is provided with invalid operation determination means for determining a user's operation mistake or mischief operation as invalid operation, and the operation determined as invalid operation is not included in the history information, so that the user memorizes it. Since the operation that is not desired does not remain in the history information and more appropriate statistics are obtained, it is possible to obtain an effect that the possibility that the predicted driving matches the intention of the user is increased.

  Furthermore, since the user is provided with an automatic driving selection means for selecting whether to enable or disable the automatic driving, the user goes out urgently or is absent for a long time on a trip or business trip. If you do not want automatic driving, you can respond by selecting automatic driving invalidation in advance, so you can also respond when you want to disable automatic driving and the effect that driving that matches the user's intention is performed Can be obtained.

  In addition, although it was judged that it was a user's life pattern with the ratio of the driving mode 60% or more about driving | running assumption process, since a variation degree changes with users, a threshold value is adjusted between 50%-80%. It is desirable.

  In addition, about the driving | running assumption means, it assumed that driving | running was assumed from the statistics for 30 days and weighted for every day unit in the example of the history information of FIG. It is good also as what assumes driving | running | working weighting and outputs the driving | running assumption result of the day.

(Embodiment 2)
In the first embodiment, when the operation assumption process is less than 60%, it is determined that there is no regularity and the automatic operation process is not performed, but a typical operation plan is assumed for each season. Instead of the result, it is proposed. This operation assumption process will be described with reference to FIG. As shown in FIG. 7, in step S014, if the ratio of the driving mode of the driving estimation result assumed by weighting the obtained statistical data on a daily basis and taking the statistics is 60% or more, the life of the user It is determined that the pattern matches the user's intention, and the automatic driving process in step S015 is performed. Since the automatic driving process is the same as that of the first embodiment, the description thereof is omitted. When the ratio of the operation mode of the operation assumption result is less than 60%, it is determined that there is no regularity, and a typical operation plan is proposed for each season in step S016 for the user instead of the operation assumption result. Performs operation plan data acquisition processing.

  The seasonal operation plan data acquisition process will be described with reference to FIG. As shown in FIG. 8, when it is from March to May from the date and time acquired from the clock function of the microcomputer in step S017, it is determined that the season is spring, and the operation for spring in step S018 is performed. A spring operation plan reading process for reading the plan instead of the operation assumption result is performed. In step S019, in the same way as in step S017, when it is from June to August from the date and time, it is determined that the season is summer, and the summer driving plan of step S020 is read instead of the driving assumption result. Read the operation plan. In step S021, if it is from September to November from the date and time as in step S017, it is determined that the season is autumn, and the autumn driving plan in step S022 is read instead of the driving assumption result. When the operation plan reading process is performed, and none of the above is December, January, or February, it is determined that the season is winter, and the winter operation plan in step S023 is used instead of the assumed operation result. Perform the winter operation plan reading process.

  A data example of the seasonal operation plan data is shown in FIG. As a general usage example every spring, summer, autumn, and winter, an hourly operation plan is stored in a ROM area of a microcomputer or a storage means such as an EEPROM.

  According to such a configuration, the driving assumption means obtains history information in units of one hour, takes statistics by weighting in units of one day, predicts optimum driving, and statistics of driving modes are predetermined. If the statistic does not reach the specified ratio by adopting automatic driving based on the automatic driving plan for each season that is stored in advance, it is possible that the day starts to be collected and the day is shallow. Therefore, by putting a typical operation plan in place, it is possible to obtain an effect that the possibility of matching with the user's intention becomes high.

  The bathroom ventilation heating / drying apparatus according to the present invention allows the user to know in advance when and what kind of automatic operation will start, to enable or disable execution, and to enable operation that matches the user's intention. Therefore, it is useful not only for bathrooms but also for applications such as air conditioners.
