Abstract

An automatically operated soap dispenser and hand dryer are provided in a single housing. The housing encloses a horizontally disposed transparent cylindrical chamber having an open front end and an opening in the upper wall thereof opposite which a self-sealing nipple valve on the end of a tubular member of a disposable liquid soap container resides. A cyclically operated actuating means located in the housing above the cylindrical chamber is controlled to automatically squeeze the tubular member and supply a single quantity of soap through the nipple valve in response to an upturned palm of a hand of the user being inserted into the cylindrical chamber The automatic hand dryer located in the housing below the cylindrical chamber provides for automatically discharging warm air through an outlet thereof in response to the hands of the user being positioned adjacent thereto.

Claims

1. Apparatus for use in washing the hands of a user comprising:

a housing including an upper portion and upper and lower intermediate portions for enclosing an automatic soap dispenser and a lower portion for enclosing an automatic hand dryer;

said automatic soap dispenser comprising;

a disposable container of liquid soap located in the upper portion of the housing;

a resilient tubular member connected at one end thereof to the interior of the container and extending down through the upper intermediate portion of the housing, said tubular member having a self-sealing nipple valve on its opposite end;

actuating means including a motor means and a squeezer means, said squeezer means located in said upper intermediate portion in front of said tubular member; and

a horizontally disposed transparent cylindrical chamber located in the lower intermediate portion of the housing and having an upper wall with an opening therein aligned with the nipple valve; and

a first sensor located in said cylindrical chamber responsive to a hand placed therein to actuate said actuating means to cause said squeezer means to move from a rest position to press said tubular member and supply a dosage of soap from said tubular member into the hand of the user and then return to said rest position;

said automatic hand dryer comprising;

a warm air blower located in said lower portion of said housing beneath said cylindrical chamber;

said warm air blower having an outlet; and

a second sensor located adjacent said outlet and responsive to the hands of a user positioned opposite the outlet to energize the hot air blower to dry the hands.

2. Apparatus for use in washing the hands of a user as defined in claim 1 wherein a common power supply is provided for the automatic soap dispenser and the automatic hand dryer.

3. In a housing for use in washing the hands of a user comprising:

a horizontally disposed cylindrical chamber with an open front end and at least side walls formed of a transparent material and including an upper wall with an opening therein;

an automatic soap dispenser means located in the housing above said cylindrical chamber for automatically supplying a quantity of soap through the opening in the upper wall of the chamber in response to the upturned palm of a hand of the user inserted into the front opening thereof; and

an automatic hand dryer located in said housing below said chamber, said hand dryer including an outlet for discharging warm air when the hands of a user are positioned opposite the outlet.

4. In a housing for use in washing the hands of a user as defined in claim 3 wherein said chamber has a bottom wall and includes a removable drip tray adapted to be positioned in the bottom interior of the chamber, said tray having a well located on its upper surface so as to be vertically aligned with the opening in the upper wall of the chamber.
