[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a nozzle 2 protruding into a toilet bowl 1 and jetting washing water to a local part of a human body.
A sanitary washing device including a water supply path 3 for supplying washing water to the nozzle 2 is known. In this case, the water supply path 3 is connected to a water pipe via a water supply solenoid valve 10, and the water supply path 3 has a water supply tank 11 and a water supply pump
Numerals 12 are arranged in this order, and a heater 13 for warming the washing water stored in the water supply tank 11 is provided.

Accordingly, in this case, the cleaning water heated by the heater 13 in the water supply tank 11 is blown out from the nozzle 2 to a local part of the human body by the operation of the water supply pump 12, so that a comfortable anal cleaning or bidet cleaning is performed. It can be performed.

[0004]

However, at present,
As the prevalence of sanitary washing devices has increased and the desire for cleanliness in anal cleaning or bidet cleaning has been increasing, in the above-mentioned conventional technology, dirt (remaining stool) that has adhered to wrinkles (folds) in the anus or in the local area of a woman. Etc.) cannot be completely removed, and in order to solve the problem, it has been expected that more effective cleaning is performed by mixing a cleaning agent with cleaning water. In addition, many people suffer from hemorrhoids, and it has been desired for such patients to mix and disinfect a disinfectant or other chemicals effective for the prevention or treatment of hemorrhoids with washing water.

Therefore, as shown by a two-dot chain line in FIG. 3, it has been proposed to store a chemical such as a detergent or a disinfectant in the chemical tank 7 and mix the chemical into the washing water in the middle of the water supply path 3. It became so. However, in this case, there is a problem that it is difficult to stabilize the washing water mixed with the medicine to a desired concentration of the medicine, and an optimum washing action cannot be obtained. That is, it is necessary to accurately maintain the concentration of the medicine itself stored in the medicine tank 7, and the concentration of the medicine after the medicine is mixed with the washing water varies depending on the amount of the washing water or medicine mixed. It was easy and hard to stabilize.

SUMMARY OF THE INVENTION The present invention has been made in order to solve all the problems in the prior art described above, and an object of the present invention is to easily wash water containing a chemical such as a detergent and a disinfectant with a desired chemical concentration. It is an object of the present invention to provide a sanitary washing apparatus capable of supplying a stable washing water to a nozzle and jetting out washing water having the same chemical concentration from the nozzle to obtain an optimum washing action.
