  FIG. 2 shows an internal configuration diagram of the deodorizing means 6 provided in the local cleaning device 1 according to Embodiment 1 of the present invention.

  In FIG. 2, the deodorizing means 6 assembled to the bottom plate (not shown) of the main body 2 is provided with an odor suction port 11 facing the toilet inner space A through the opening of the bottom plate. A duct through which the odor discharge port 12 communicates is provided on the side surface or the back surface of the main body 2, and the odor suction port 11 and the odor discharge port 12 communicate with each other through a passage member 13 to form an air passage 17. A dust filter 14 is detachably provided at the odor suction port 11, and a blower 15 and a deodorizer 16 are provided at the air passage 17.

  FIG. 3 is a functional block diagram of the local cleaning apparatus according to the first embodiment of the present invention. Moreover, FIG. 4 is explanatory drawing of the operation part 25 in the local washing | cleaning apparatus of Embodiment 1 of this invention.

  3 and 4, the main body 2 is provided with a control board 18 (not shown) for controlling the operation of various functions such as toilet seat, opening / closing of the toilet lid, local cleaning, deodorization, and drying. The control unit 19 provided in is provided with an elapsed time calculation unit 20, a power saving unit 21a, and a notification unit control unit 24a. An operation unit 25 provided in a part of the main body is an operation unit for a user to set the temperature of various function units of the main body or to instruct the execution of various functions. The switch 21b, the cleaning switch 22a, the drying switch 22b, and reset means 26 for instructing resetting the accumulated time of the elapsed time calculating means are provided. Furthermore, a notification means (display unit) 24b for performing display based on a notification signal issued from the notification means control unit 24a is also provided.

  The operation and action of the local cleaning apparatus configured as described above will be described below.

  In the above configuration, when the seating detection means 9 detects that a person sits down on the toilet seat 4 at the time of defecation, the blower 15 provided in the deodorizing device 19 automatically operates in response to a signal from the control unit 19, An air flow is generated in the air passage 17 from the odor suction port 11 to the odor discharge port 12. Air containing malodorous components during defecation passes through the deodorizer 16 and is deodorized. At this time, dust is also sucked at the same time as the malodorous component, but the dust is removed by the dustproof filter 14, and only the malodorous component is purified and exhausted from the side surface or the back surface of the main body 2 to the toilet room space. When the user defecates, performs local cleaning, and leaves the toilet seat 4, the seating detection means 9 detects. The air blower 15 is stopped after a certain period of time after the seating detection means 9 detects the separation and it is estimated by the control unit 19 that the deodorizing means 23 operates sufficiently. The elapsed time calculating means 20 installs the local cleaning device in the toilet room and integrates the elapsed use time after the start of use.

  A case where the user sets power saving with the power saving setting switch 21b will be described. When power saving is set by the power saving setting switch 21b, in order to reduce standby power in times when the local cleaning device is not frequently used, such as at night, a local type that keeps the toilet seat warm or stores hot water. If it is a washing | cleaning apparatus, it controls so that the heat retention temperature may be kept warm at the temperature somewhat lower than the preset temperature set by the user who is used in the time zone with high use frequency. Also, for the type that does not hold heat or store hot water, which is said to be instantaneous, the power supply to each functional unit can be stopped, and power can be used only to hold the safety circuit, and operation can be started when use is detected. To wait. Here, the power saving time is set to about 8 hours. In the elapsed time calculation means 20, the elapsed time is not accumulated in the time zone in which the power saving setting switch 21b is pressed and the power saving means 21a is functioning.

Then, in the elapsed time calculation means 20, a notification means for notifying that the cleaning time of the dustproof filter 14 is reached when a predetermined time (the elapsed time that the driving time of the deodorizing means corresponds to the replacement time of the dustproof filter) has elapsed. A signal is sent from the control unit 24a to the notification unit (display unit) 24b, and the notification unit (display unit) 24b notifies the user by blinking the LED. This informs the user that it is time to clean the dust filter 14, so that the user can prevent the user from forgetting to clean the dust filter 14.

  Then, the resetting means 26 resets the accumulated time of the elapsed time calculating means 20, and starts to accumulate the next elapsed time. The reset means 26 in the present embodiment is not provided as an independent separate switch, but is also used as a switch for instructing other functions provided in the operation unit 25. Here, the control unit 19 determines that the reset unit 26 has been pressed by simultaneously pressing the cleaning switch 22a and the drying switch 22b. In this way, the operation unit 25 does not reset by mistake by performing a special operation that cannot be a button operation of the switches of the operation unit in the normal use of the local cleaning device.

  In the conventional local cleaning apparatus, the deodorizing means 6 always operates when the user sits on the toilet seat and uses the toilet, so that the dustproof filter 14 is clogged and the suction force is reduced when used for a long period of time. Affects ability. Since the cleaning time of the dust filter 14 is usually about one month, it is described in an operation manual or the like and relies on the user's voluntary cleaning. In some cases, such as when you forget what you need, cleaning may not take place after a month. There was also concern that the deodorizing function would not function sufficiently. Therefore, as in the present invention, by performing notification so as to prompt the user to clean, the dust filter 14 can be cleaned by the user, and the ability of the deodorizing means 6 can be fully exhibited.

  Further, when the power saving function is set, the elapsed time calculation means 20 does not accumulate the elapsed time on the assumption that the local cleaning device itself is hardly used in the power saving time zone. When the power saving function is not used, the elapsed time calculation means 20 adds up the period of about one month from the installation of the local cleaning device. However, if the power saving function is set, In the embodiment, one-third of the day of 8 hours is in the power saving mode, which is 30% longer than the usable time of the dust filter 14 of the deodorizing means 6 compared to the case where the power saving function is not used. . By setting it as such a structure, the user can extend the use period of the dustproof filter 14, and can perform a maintenance at an appropriate time.

  Moreover, in this Embodiment 1, although the alerting | reporting means (display part) 24b is made to alert | report by blinking or lighting with illumination electrical components, such as LED, it is not restricted to this, As a structure which consists of mechanical means. Also good. Moreover, although this was provided in the operation part provided in a part of main body, you may make it display by the remote operation means provided in the main body separately. In addition, while detecting the user who entered the room by installing the room detection sensor, etc., the seating detection sensor detects the seating or when the seating is confirmed, that is, the user is surely in the toilet room. You may make it alert | report by a sound at a timing. This further increases the effect of preventing forgetting to clean.

  Moreover, although this invention is invention about the maintenance of a deodorizing apparatus, it is applicable also to alerting | reporting the maintenance information of the functional unit which needs another maintenance.

  As described above, the local cleaning device according to the present invention notifies the user of the regular maintenance time of the dust filter that the deodorizing means has, and encourages the user to perform maintenance work. It can also be applied to notification of periodic maintenance times in the apparatus.
