DESCRIPTION:
BRIEF SUMMARY
Known washstands have, among other things, a basin with water faucets and drainage, and a device for drying the hands. Much has been said in the past about the hygiene of such washstands.
It has also been explained, for example, that the water faucet should not be operated manually, since touching it with the unwashed hand, as is generally done, may have the effect of transmitting germs from user to user.
Many discussions of known devices for drying the hands have been published. The hygiene of the many different types of hand towel has also been argued. After a sufficiently long wait, the automatic hand towel always supplies a clean section of the cloth roll. Also known are devices for providing paper or cloth napkins for drying the hands. Aside from careless handling of the napkins, pulling them away incorrectly and/or wasting them, bits of them scatter through the air in the room, thus spreading the germs with which they are covered.
The hot-air hand dryer was then developed as an alternative, in which the air drawn from the room or the fresh air drawn into it is blown downward after flowing through an air heater in one stream or in two intersecting streams. But here again hygienic considerations are somewhat neglected since the germs may eddy around the room by means of the relatively strong air stream from the hot-air hand dryer.
It can therefore be considered that no washstand that can be used to wash and dry the hands under completely hygienic conditions is now available.
The purpose of the invention is to improve the precarious relationships described above with a washstand design having a basin, water supply, and drainage, with a hot-air hand dryer, in accordance with the introductory paragraphs of the independent patent claim.
This purpose is accomplished by the features of the independent patent claim of the invention.
A prototype of the invention is described below with the aid of the drawing, in which:
FIG. 1 shows a cutaway profile view of the washstand invention, and
FIG. 2 shows a front view of the washstand of FIG. 1 with a cutaway view of the lower section.
No special indications of the wall thicknesses for the housing are given in the drawing; they are merely sketched in.
The housing 10 includes a wash basin 11 with a water supply pipe 21 and a drainpipe 27 with an odor remover, as well as a hot-air hand dryer 12 with a ventilator section 20, an air heater section 19, and an air vent 18. Running near the water supply pipe 21 is a second pipe 23, carrying a fluid cleanser--liquid soap, for example--which is pumped upward from its supply source 24 by a dosage pump 29. The water supply nozzle 22, the nozzle 30 of the pipe 23, and the air vent 18 are all in the same area.
The housing 10 is built with a double wall, and consists of a front wall 13 with an outer wall 130 and an inner wall 131, two side walls 14 and 15, each with an outer wall 140 and 150 and an inner wall 141 and 151, as well as a rear wall 16 with an outer wall 160 and inner wall 161. There are also a cover 31 and an outer wall 310 and an inner wall 311, as well as a floor 32 with an outer wall 320 and an inner wall 321. The inner wall 321 of the floor 32 forms the inner contour of the wash basin 11, and the inner wall 311 of the cover 31 contains the apertures for the air vent and the water and soap supplies 21 and 23. The inner wall 161 of the rear wall 16 has an air exhaust opening 17.
All the inner walls 131, 141, 151, 161, 311, and 321, surround a wash chamber 40 with an opening 41 in the front wall 13, which permits both hands 50 to enter comfortably.
Along with the feed pipes 21 and 23 for water and soap, mentioned above, another container for the care of the head can be installed in the wash chamber 40 with another feed pipe. To keep the diagram simplified, this equipment is not shown; this additional device may take the same form as the soap-dispensing system, with its supply source 24, the dosage pump 29, feed pipe 23, and nozzle 30.
The nozzle of the water pipe could be made in the form of a shower head. Supply for
