DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a sanitary washing apparatus used for washing the private parts of the human body with comfortably warm water, for example.
BACKGROUND ART
In recent years, sanitary washing apparatus combined with Western style toilet bowls have become widespread. One type of these sanitary washing apparatus employs a single washing nozzle which is used both as a device for washing the anus and as a bidet. However, this type of apparatus are surpassed in function by sanitary washing apparatus which are provided both with a nozzle that is exclusively used for washing the anus and with a bidet nozzle, since the lather apparatus makes it possible to obtain the proper positions and angles for jetting out washing water. Such sanitary washing apparatus having both types of nozzle are disadvantageous however in that the water passage for passing warm water is incoveniently long.
FIGS. 1 and 2 in combination show a conventional sanitary washing apparatus, which is composed of a toilet bowl 1, a toilet seat 2, an anus washing nozzle 3 and a bidet nozzle 4 which are disposed on the toilet seat 2, and a washing apparatus body 5 which is installed on the floor and accommodates therein a hot-water tank, a pressurizing pump, a controller, etc. The anus washing nozzle 3 and the bidet nozzle 4 are supplied with the hot water in the hot-water tank through connecting hoses 3', 4' which respectively provide communication between the washing apparatus body 5 and the nozzles 3, 4. Further, the washing apparatus body 5 is provided with a hot-water temperature adjusting knob 6, a hot-water quantity adjusting knob 7 and a function changeover knob 8.
FIGS. 3, 4 in combination show another conventional sanitary washing apparatus, which includes a toilet bowl 9 provided with an anus washing nozzle 10 and a bidet nozzle 11 which are supplied with hot water through respective connecting hoses 10', 11' from a washing apparatus body 13 which is installed on the floor and accommodates therein a hot-water tank, a pressurizing pump, a controller, etc. In addition, this sanitary washing apparatus is provided with a toilet seat 12, a power switch 14, a hot-water temperature adjusting knob 15, a hot-water quantity adjusting knob 16 and a function changeover knob 17, similarly to the apparatus shown in FIGS. 1, 2.
Both the above-described conventional sanitary washing apparatus have inconveniently long water passages, respectively extending from the hot-water tanks accommodated in the washing apparatus bodies 5, 13 to the anus washing nozzles 3, 10 and the bidet nozzles 4, 11; therefore, the hot water discharged from the hot-water tanks by a washing operation takes a long time to reach the end of each nozzle. More specifically, since the washing water remaining in the connecting hoses 3', 4'; 10', 11' during the suspension of operation has cooled down to become warm water of relatively low temperature, this rather cold water must be jetted out and removed before the hot water is discharged from each of the nozzles 3, 4; 10, 11. It is extremely unpleasant for a person to be sprayed with a jet of cold water, even for a short time, prior to jetting out of hot water by a washing operation, particularly when the room temperature is low in the winter.
According to the arrangement of each of the above-described sanitary washing apparatus, the user sits on the toilet seat 2, 12 and after bowel movement actuates the function changeover knob 8, 17 to wash the anal part with the anus washing nozzle 3, 10. In the case of a woman in her menstrual period, she washes the female genital parts with the bidet nozzle 4, 11. Particularly in the case of a woman, it is common practice to wash the genital parts with the bidet nozzle after washing the anus even in the case of defecation and to wash the anus after washing the genitalia when she is in her menstrual period. In other words, it is frequent practice for women to use both nozzles, one after the other.
The conventional sanitary washing apparatus, however, are extremely dis
