Abstract

The present invention relates to a sanitary equipment which is provided in a toilet attached to a clean room. The side surface of the body of the sanitary equipment is made almost vertical, and fixation elements for fastening the body of the equipment onto the wall of the toilet do not protrude into the toilet. As a result, air is circulated through the toilet in such a manner that the air flowing down in the toilet is not disturbed.

Claims

1. Sanitary equipment used for hand washing and being disposed for use in a sanitary equipment installation composed of a chamber having sides including at least one wall and a floor, said sanitary equipment comprising:

(a) an equipment body having a substantially vertical front portion and a rear portion;

(b) means for attaching said equipment body to a wall of said chamber so that said rear portion is embedded in said wall, said means for attaching not projecting into said chamber;

(c) means for forming an open portion in an upper part of said equipment body about said front portion of said equipment body, said open portion having an opening which opens into said chamber, and which provides access to a pot-shaped portion in a lower part of said equipment body, said means for forming an open portion extending towards said rear portion and said pot-shaped portion;

(d) said means for forming an open portion including a first engaging portion and said front portion including a second engaging portion, said first engaging portion and second engaging portion enganging the side of said wall facing said chamber when said rear portion of said equipment body is embedded in said wall, wherein only said substantially vertical front portion said open portion and said first and second engaging portions are housed in the chamber, thereby allowing laminar flow of air in the chamber relative to the sanitary equipment to substantially prevent dust from adhering to the sanitary equipment.

2. The sanitary equipment according to claim 1, wherein said equipment body comprises a washstand.

3. The sanitary equipment according to claim 1, wherein said equipment body further comprises:

(i) a water feeder for supplying water to said equipment body; and

(ii) a sensor for automatically opening and closing said water feeder at appropriate times responsive to actions of a user of said sanitary equipment.

4. The sanitary equipment according to claim 3 wherein said sensor comprises an infrared sensor.

5. The sanitary equipment according to claim 3 wherein said equipment body is a washstand, said washstand further comprising:

(i) said water feeder supplying water to said washstand through a water ejector;

(ii) an air discharge fan for sucking air out of said chamber;

(iii) a blowoff port for ejecting warm air to dry the hands of said user;

(iv) a heater for heating said warm air;

(v) an air feed fan for blowing said warm air through said blowoff port; and

(vi) a controller electrically connected to said water feeder, said air discharge fan, said sensor, said heater and said air feed fan, for controlling said water feeder, said air discharge fan, said heater and said air feed fan in response to said sensor.

6. The sanitary equipment according to claim 3, said pot-shaped portion including a brim at the upper portion thereof, and a water passage being located at said brim.

7. The sanitary equipment according to claim 1, wherein said means for forming an open portion is a cover extending over said pot-shaped portion.

8. The sanitary equipment according to claim 1, said open portion including an upper edge, said upper edge being substantially flush with the surface of said wall.
