BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary washing device having a local washing function, and particularly when a nozzle for jetting washing water is self-cleaned before or after use, the hygiene is indicated. Cleaning device

[0002]

2. Description of the Related Art A sanitary washing apparatus having a local washing function generally employs a structure in which heated washing water is jetted toward a local portion by a nozzle device.

This nozzle device is disclosed in, for example, Japanese Patent Publication 1-5.
As described in Japanese Patent No. 2532, a nozzle main body that advances from a storage position to a cleaning position by a motor is provided, and cleaning water is sprayed from a jet hole formed at the tip of the nozzle main body at the cleaning position to locally cover the nozzle. Has the function of cleaning.
In addition, instead of the nozzle main body for this advancing operation, there is also one in which a storage position is provided under the toilet seat or the like and the nozzle main body is manually rotated to set the cleaning position.

When the nozzle device of the sanitary washing device is used, it may be covered with dirty water or dirt during washing. Therefore, it is preferable to wash the tip of the nozzle body by washing before or after use. Various types of nozzle bodies are used for cleaning such nozzle bodies depending on the structure for sending cleaning water for cleaning. For example, in the above publication, after returning the nozzle body to its storage position, cleaning water for local cleaning is supplied again, and the supplied cleaning water flows down around the tip of the nozzle body. Is becoming In addition, there is also one in which a cleaning path is provided in addition to a supply path for cleaning water for local cleaning, and cleaning is performed for a certain time by operating an opening / closing valve such as a solenoid valve.

As described above, the mainstream of the method is to clean the nozzle body automatically before or after the local cleaning, or by a switch operation by a person before use.

Recently, the sanitary washing device having a local washing function has been widely used not only in general households but also in hotels, department stores, hospitals and other facilities. Therefore, with the specifications for home use,
Some aspects are not suitable for public use, and various improvements have been made as necessary.

In the conventional specifications for household use, no indicator lamp or the like for informing a user of cleaning the nozzle body is incorporated. This is partly due to the design concept that it is not necessary to inform the user because it is for home use and cleaning is performed in a hidden position before or after local cleaning.

In the case of public use, however, a large number of people use it, so that cleanliness is strongly desired. For this reason, even though the nozzle body is actually cleaned to clean the nozzle body, the user does not know that the cleaning process is performed, and the anxiety remains. This is true not only for public use but also for general household use.

As described above, since the nozzle cleaning is not positively displayed, the discomfort of the user who uses the nozzle cannot be eliminated, and this tendency becomes remarkable especially in the case of public use. And, although the cleaning water is actually obtained from the clean nozzle after cleaning, if this is not appealed, it will impair the user's sense of security, and the function of breakage will not be fully understood. Ends with.

The problem to be solved in the present invention is to inform the user of the cleaning of the nozzle positively to let the user know that the nozzle is kept clean, and to remove the discomfort and anxiety from those who use it for comfortable cleaning. Is to be able to do.

The present invention relates to a sanitary washing device provided with a nozzle device for local washing and a mechanism for cleaning at least the washing water jet end of the nozzle device with washing water for cleaning. Is provided with an informing means for informing the process.

Further, the cleaning device is provided with a display unit for displaying the jetting of the cleaning water from the nozzle device, and the display state of the display unit is made different between the jetting of the cleaning water and the process of the nozzle cleaning so that the cleaning process is performed. It can also be used as an informing means for informing.

[0013]

When the cleaning water jetting end of the nozzle device is cleaned, the user can be informed that the cleaning process is in progress by the notifying means. Therefore, for example, when the cleaning is performed before the local cleaning, the user can recognize that the ejection end portion of the nozzle device is cleaned to be in a clean state and used for the local cleaning. Therefore, the user can rest assured that he / she can rely on the cleaning by the nozzle device, and the comfortable cleaning can be performed including the mood.

Further, if the display means for displaying the fact that the cleaning water is being jetted by operating the nozzle device is made to display a different display indicating that it is in the process of nozzle cleaning, it is possible to use for nozzle cleaning. There is no need to provide a separate display.

Make the sound output repeatedly. If such a speaker 28 is provided, the user can easily know that the nozzle head 4 is cleaned without looking at the operation panel 20 one by one.

As described above, by utilizing the blinking of the indicator lights 22a and 23a, the display on the liquid crystal screen 27 and the sound from the speaker 28, the nozzle body 3 is used before and after use.
It is possible to easily inform the user that the nozzle head 4 has been cleaned. Therefore, for the user, the nozzle body 3 that is about to be used for cleaning now
Can recognize that it has been cleaned and is in a clean state, and can be used comfortably without feeling unclean or uncomfortable.

In the embodiment, the cleaning is performed twice before the nozzle body 3 is advanced to the cleaning position and when it is returned to the storage position after use, but only before or after use. It can also be cleaned. Further, in addition to providing the cleaning chamber 2b for cleaning, a cleaning mechanism may be used in which cleaning water is flown over the peripheral surface of the nozzle head 4 to wash it off, as described in the publications cited in the section of the prior art.

The indicator lights 22a and 23a of the operation panel 20 are also provided.
The blinking time indicating the nozzle cleaning can be arbitrarily set such as longer than the cleaning time of the nozzle head 4 regardless of before or after using the nozzle device. Further, although the operation panel 20 is provided on the casing 1 fixed to the toilet body 50, it may be replaced with a remote controller which can be used by being hung on a wall in the toilet.
