TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sanitary washing device having a detachable external pump unit.
[0002]
[Prior art]
Heretofore, this type of sanitary washing device has been generally described in JP-A-61-2557547. As shown in FIG. 9, this device is a water circuit diagram dedicated to a pump water supply type that can be used in a non-flush toilet or a flush toilet (low water pressure area). A hot water tank 4 for heating the washing water by a pump 2 and a hot water heater 3 for pressurization, an electromagnetic valve 5 for switching a flow path of the washing water, and a hose 7 for leading the washing water to a nozzle 6 for washing a human body or And a hose 9 for guiding washing water to a nozzle 8 for washing a human body.
[0003]
With the above configuration, the wash water from the water supply tank 10 is pressurized by the pump 2 and enters the hot water tank 4. Further, the washing water is heated by the hot water heater 3 of the hot water tank 4 and enters the solenoid valve 5. Since the electromagnetic valve 5 is opened at the same time as the operation of the pump 2, hot water is ejected from the nozzle 6 through the hose 7 from the outlet of the electromagnetic valve 5. Further, when the electromagnetic valve 5 is switched, it is configured to be ejected from the nozzle 8 through the hose 9 to clean the human body.
[0004]
[Problems to be solved by the invention]
However, there are two types of conventional sanitary washing devices: a water supply system that can be used in flush toilets (high and medium water pressure areas) and a pump water supply method that can be used in non-flush toilets and flush toilets (low water pressure areas). This is necessary and has a problem that production management and distribution management become complicated.
[0005]
In addition, when a household using a sanitary washing device is currently moving, there is a problem that a part of the sanitary washing device cannot be used and must be replaced.
[0006]
Further, when the pump breaks down, there is a problem that much time is required for repair and replacement.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is configured such that a sanitary washing device main body to be mounted on a toilet and used, and an external pump unit having a pump inside and supplying water are detachably attached. .
[0008]
According to the above invention, since the sanitary washing device main body can be easily converted from a water supply system directly connected to a water supply system to a pump water supply system, production management and distribution management are facilitated, and households currently using the sanitary washing device are used. When the pump is moved, it is no longer unusable, and repair and replacement can be easily performed when the pump breaks down.
