Abstract
Abstract A hand sanitizing wash station including a sink, a soap dispenser located above the sink for supplying soap, a water dispensing faucet located above the sink operated by a solenoid valve, a hot-air dryer located above the sink for supplying hot-air, a first infrared sensor for detecting the proximity of a user, the first sensor being operatively connected to the soap dispenser and the solenoid valve to activate the soap dispenser and the solenoid valve upon detecting the presence of a user, and a second infrared sensor for detecting the presence of a user, the second sensor being operatively connected to the solenoid valve and the hot-air dryer such that the second sensor will deactivate the solenoid valve and will activate the hot-air dryer.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
145 words
A sanitizing device comprising a housing including means for dispensing soap; means for dispensing water; first sensor means for detecting the proximity of a user, said first sensor means being operatively connected to said soap dispensing means and to said water dispensing means such that upon sensing the proximity of a user said first sensor means activates said soap dispensing means and activates said water dispensing means; dryer means for dispensing heated air; and second sensor means for detecting the proximity of a user, said second sensor means being operatively connected to said dryer means such that upon sensing the proximity of a user said second sensor means activates said dryer means and wherein said second sensor means is additionally operatively connected to said water dispensing means such that upon sensing the proximity of a user said second sensor means deactivates said water dispensing means.
Claim 2
Dependent Claim
145 words
A sanitizing device comprising a housing including means for dispensing soap; means for dispensing water; first sensor means for detecting the proximity of a user, said first sensor means being operatively connected to said soap dispensing means and to said water dispensing means such that upon sensing the proximity of a user said first sensor means activates said soap dispensing means and activates said water dispensing means; dryer means for dispensing heated air; and second sensor means for detecting the proximity of a user, said second sensor means being operatively connected to said dryer means such that upon sensing the proximity of a user said second sensor means activates said dryer means and wherein said second sensor means is additionally operatively connected to said water dispensing means such that upon sensing the proximity of a user said second sensor means deactivates said water dispensing means.
Claim 3
Dependent Claim
50 words
The sanitizing device of claim 1 additionally including means operatively connected to said first sensor and to said water dispensing means for delaying the deactivation of said water dispensing means by said second sensor means until said water dispensing means has been operative for a minimum predetermined length of time.
Claim 4
Dependent Claim
27 words
The sanitizing device of claim 2 wherein said delay means is adjustable to provide various minimum time periods of operation of said water dispensing means as desired.
Claim 5
Dependent Claim
42 words
The sanitizing device of claim 1 additionally including means operatively connected to said first sensor means and to said water dispensing means for deactivating said water dispensing means after said water dispensing means has been operative for a predetermined length of time.
Claim 6
Dependent Claim
32 words
The sanitizing device of claim 4 wherein said deactivation means is adjustable to deactivate said water dispensing means after said water dispensing means has been operative for any desired length of time.
Claim 7
Dependent Claim
48 words
The sanitizing device of claim 1 additionally including means operatively connected to said first sensor means and to said water dispensing means for delaying the activation of said water dispensing means for a predetermined length of time after said first sensing means has activated said soap dispensing means.
Claim 8
Dependent Claim
36 words
The sanitizing device of claim 6 wherein said delay means is adjustable to provide various periods of delay as desired between the activation of said soap dispensing means and the activation of said water dispensing means.
Claim 9
Dependent Claim
42 words
The sanitizing device of claim 1 additionally including means operatively connected to said first sensor means and to said soap dispenser means for deactivating said soap dispenser means after said soap dispenser means has been operative for a predetermined length of time.
Claim 10
Dependent Claim
32 words
The sanitizing device of claim 8 wherein said deactivation means is adjustable to deactivate said soap dispenser means after said soap dispenser means has been operative for any desired length of time.
Claim 11
Dependent Claim
39 words
The sanitizing device of claim 1 additionally including means operatively connected to said second sensor means and to said dryer means for deactivating said dryer means after said dryer means has been operative for a predetermined length of time.
Claim 12
Dependent Claim
29 words
The sanitizing device of claim 10 wherein said deactivation means is adjustable to deactivate said dryer means after said dryer means has been operative any desired length of time.
Claim 13
Dependent Claim
16 words
The sanitizing device of claim 1 additionally including means for disabling said first and second sensors.
Claim 14
Dependent Claim
20 words
The sanitizing device of claim 1 additionally including means for providing manual activation and deactivation of said water dispensing means.
Claim 15
Independent Claim
98 words
A method of dispensing soap, water and heated air for sanitizing hands comprising the steps of: connecting a first proximity sensor to a soap pump motor; connecting said first proximity sensor to a solenoid valve; activating said soap pump motor and said solenoid valve by placing at least one hand in the proximity detection range of said first proximity sensor; connecting a second proximity sensor to a dryer and to said solenoid valve; and activating said dryer and deactivating said solenoid valve by placing at least one hand in the proximity detection range of said second proximity sensor.
Claim 16
Independent Claim
98 words
