Abstract

Abstract A hygienic unit is provided for delivering water at a controlled temperature to a nozzle which provides a jet or stream of water which can be applied by a person for cleansing or sanitary purposes to any part, organ, or cavity of the body. The unit includes a manual adjusting knob for initially setting a thermostatic motor which cooperates with a valve assembly for controlling a flow of hot water for mixing with a flow of cold water such as to provide a mixed flow of water having a selected temperature. The thermostatic motor then provides for repositioning the valve assembly as required to maintain the selected temperature of the mixed water being delivered by the hygienic unit.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 302 words
A personal hygenic unit for providing a jet of water at a controlled temperature for use by a person for cleansing purposes comprising a housing having a front panel, said housing having a mixing chamber therein, a cold water inlet, a hot water inlet, and a mixed water outlet, a valve assembly in said housing for controlling the flow of hot water from said hot water inlet to said mixing chamber, a means on said valve assembly for manually adjusting the setting of said valve assembly such that the temperature of the water in said mixiNg chamber is at a desired temperature, said means having an adjustment knob on said panel, a thermostatic motor responsive to the water in said mixing chamber for automatically adjusting the setting of said valve assembly to maintain the temperature of the water in said mixing chamber at the desired temperature, a liquid line in the housing for mixed water, said liquid line being connected at one end to the mixed water outlet, a length of flexible hose in the housing connected to the liquid line at the other end for receiving the water from the mixed water outlet, a nozzle on the end of said flexible hose having attachment means at the outflow end for providing the jet of water to be used for cleansing purposes, and support means on the panel releasably holding said nozzle, a check valve in said liquid line and located in said housing, said check valve having means within the housing and remote from the panel for adjusting the check valve, a thermal sensor in said liquid line, a temperature gauge on said panel in communication with said sensor, and an assortment of attachments releasably held on said panel, said attachments being engageable alternatively with the attachment means of said nozzle.
Claim 2
Dependent Claim 302 words
A personal hygenic unit for providing a jet of water at a controlled temperature for use by a person for cleansing purposes comprising a housing having a front panel, said housing having a mixing chamber therein, a cold water inlet, a hot water inlet, and a mixed water outlet, a valve assembly in said housing for controlling the flow of hot water from said hot water inlet to said mixing chamber, a means on said valve assembly for manually adjusting the setting of said valve assembly such that the temperature of the water in said mixiNg chamber is at a desired temperature, said means having an adjustment knob on said panel, a thermostatic motor responsive to the water in said mixing chamber for automatically adjusting the setting of said valve assembly to maintain the temperature of the water in said mixing chamber at the desired temperature, a liquid line in the housing for mixed water, said liquid line being connected at one end to the mixed water outlet, a length of flexible hose in the housing connected to the liquid line at the other end for receiving the water from the mixed water outlet, a nozzle on the end of said flexible hose having attachment means at the outflow end for providing the jet of water to be used for cleansing purposes, and support means on the panel releasably holding said nozzle, a check valve in said liquid line and located in said housing, said check valve having means within the housing and remote from the panel for adjusting the check valve, a thermal sensor in said liquid line, a temperature gauge on said panel in communication with said sensor, and an assortment of attachments releasably held on said panel, said attachments being engageable alternatively with the attachment means of said nozzle.
Claim 3
Dependent Claim 28 words
A personal hygenic unit as in claim 1 wherein there is a vacuum breaker in the liquid line at a location intermediate the nozzle and the check valve.
