  By the way, in the warm air drying apparatus of patent document 1, by blowing warm air at the time of washing | cleaning, it is preventing that washing water splashes or adheres to an inner crotch part along skin, but it is not necessarily effective. It was. Because the warm air is directed from the front to the rear of the toilet, the washing water does not adhere to the inner crotch on the windward side, but the possibility of adhering to other parts of the buttocks has not been eliminated and needs to be dried. It was hard to say that the scope was localized. Moreover, although the sanitary washing apparatus of patent document 2 has shortened the switching time from washing water injection to air injection, the effect of shortening drying required time itself was small.

  The present invention has been made in view of the above background, and limits the range wetted by washing water, and by performing drying in parallel during washing, a human body local washing device that shortens the drying time than before provide.

The washing water jetting means and the air jetting means include the washing water. A washing water ejection hole for ejecting air and an air ejection hole for ejecting the air are formed, and are movable between a standby position on the base side and an operation position advanced from the standby position to the inside of the toilet by a predetermined distance. The nozzle is shared, and the control means performs control to simultaneously eject the washing water and the air for a predetermined time.

  The human body local cleaning device of the present invention comprises a base, cleaning water jetting means, air jetting means, nozzles, and control means, and simultaneously jets cleaning water and air from the nozzles so that they are wet and dry. In addition to limiting the required range, air is intensively ejected to a wet area of the human body part. Hereinafter, it demonstrates in order. The base is a member constituting the housing of the human body local cleaning device, and can be mounted on the rear part of the toilet bowl, usually on the upper surface thereof.

  The washing water jetting means is a means for jetting washing water for washing the human body local part. The washing water jetting means opens, closes, or switches the piping member, for example, a water tank for storing washing water, a nozzle described later, a piping member such as a tube or a cylinder for transferring the cleaning water from the water tank to the nozzle, and the like. And a valve member. Furthermore, a heater and a temperature sensor for maintaining the temperature of the cleaning water at an appropriate level, a flow rate sensor for checking the flow rate, and the like may be appropriately provided.

  The air ejecting means is means for ejecting air that dries the human body part. The air for drying the human body part is preferably compressed compressed air or heated hot air. Of course, it may be compressed and heated compressed air. The air ejection means includes, for example, a compressor that takes in and compresses outside air, an air tank that stores compressed air, a heater that heats the compressed air, a nozzle that will be described later, and a piping member that transfers the compressed air from the air tank to the nozzle. And a valve member that opens / closes or switches the middle of the piping member.

  The nozzle can be formed with a washing water ejection hole for ejecting washing water and an air ejection hole for ejecting air, and can be shared by the washing water ejection means and the air ejection means. The washing water ejection hole and the air ejection hole can be formed, for example, on the upper end of the nozzle. And it can be made to eject by making a washing water ejection hole connect with the above-mentioned water tank, and making an air ejection hole communicate with the above-mentioned air tank. Further, the nozzle can be formed so as to be movable between a standby position on the base side and an operation position advanced from the standby position by a predetermined distance toward the inside of the toilet. The forward and backward movement of the nozzle can be performed, for example, by an electric operation using a motor or a water pressure operation using the water pressure of the washing water.

  There is no limitation on the number, size, and shape of the washing water ejection holes and air ejection holes formed in the nozzle, but it is preferable to form them as described below, for example. That is, the air ejection hole may be formed in an annular shape around the washing water ejection hole. Alternatively, a plurality of the air ejection holes may be formed around the washing water ejection hole. In these configurations, the air ejected from the air ejection hole can be formed so as to surround the cleaning water ejected from the cleaning water ejection hole.

  The control means performs control to eject the washing water and air simultaneously for a predetermined time. The control means may perform not only cleaning water and air ejection, but also movement control of the nozzle forward and backward, temperature management of cleaning water, pressure management of compressed air, and the like. For example, a microcomputer may be used as the control means, and an operation panel may be attached, and control may be performed in accordance with a user operation command. Alternatively, control may be performed according to a preset time chart, or control may be performed based on state detection using sensors.

  It is preferable that the control means performs control to start to simultaneously eject the cleaning water and the air, stop the cleaning water first, and stop the air later. That is, it is preferable to shift to a control in which the cleaning water and air are ejected at the beginning and only air is ejected later.

  Next, the operation and action of the human body local cleaning device of the present invention configured as described above will be described. When a cleaning start command is detected by a user operating the operation panel or the like, first, the nozzle advances from the standby position to the operating position.

Next, washing water and air begin to be ejected simultaneously toward the human body part. At this time, even if the water droplet spreads over a wide area and wets the skin, the drying proceeds in parallel with the cleaning except for the part of the human body. Furthermore, in the aspect formed so as to surround the cleaning water with air, the cleaning water can be guided to the human body part in a concentrated manner, and water droplets that are to spread to other parts of the human body can be blown off. Next, when the cleaning end command is detected, the ejection of the washing water is stopped, and the wet local part of the human body is dried by the ejection of only air. At this time, the wide area around the local human body has already been dried in addition to the low wetness. In addition, air is intensively ejected to the wet human body part. Therefore, the drying time can be shortened.

  According to the human body local cleaning device of the present invention described above, the air ejected simultaneously with the cleaning water dries water droplets other than the human body local area in parallel with the cleaning, so that the drying time can be shortened. Furthermore, in the embodiment formed so as to surround the washing water with air, the washing water is intensively guided to the human body part, and the water droplets that are to spread to other parts of the human body part are blown away, and the drying time is further shortened. The In addition, since air is intensively ejected to the wet human body part, the effect of shortening the drying time becomes more conspicuous with the effect of using compressed air or warm air.
