Abstract

A hand hygiene on board of a vehicle includes a washing device including a water supply device, a basin device with a hand receiving device and a water collecting region with a discharge opening, and a drying device including an air discharge device for generating an air stream in the hand receiving region The air discharge device is connected to the hand receiving region and a negative pressure device connected to the air discharge device. The stream of air for the hand drying process is generatable by the negative pressure device. The air discharge device is connected to the discharge opening of the basin device such that air and fluids are discharged via the discharge opening, which forms a common disposal opening. The negative pressure device is additionally designed for suctioning solids thrown into the water collecting region, besides fluids, for disposal over the common disposal opening.

First claim

The invention claimed is:

1. A hand hygiene arrangement for the use on board of a vehicle, comprising:
a washing device;
a basin device; and
a drying device;
wherein the washing device comprises a water supply device for a hand washing process and a spray nozzle;
wherein the drying device comprises an air discharge device for a hand drying process for generating a stream of air for the hand drying process;
wherein the arrangement comprises a hand receiving region, wherein the stream of air is generatable in the hand receiving region;
wherein the air discharge device is connected to the hand receiving region and wherein the arrangement comprises a negative pressure device, which is connected to the air discharge device, wherein the stream of air for the hand drying process is generatable by the negative pressure device;
wherein the basin device comprises the hand receiving region and a water collecting region comprising a discharge opening in communication with the negative pressure device;
wherein the discharge opening is configured to permit an unobstructed passage between the basin device and the negative pressure device;
wherein the spray nozzle is arranged above the basin device and the hand receiving region;
wherein the air discharge device is connected to the discharge opening of the basin device such that air and fluids are discharged via the discharge opening, which forms a common disposal opening; and
wherein the negative pressure device is configured for suctioning solids thrown into the water collecting region, besides fluids, for disposal over the common disposal opening.

2. The hand hygiene arrangement according to claim 1 , wherein the negative pressure device is configured for suctioning paper towels thrown into the basin device for a disposal over the common disposal opening.

3. The hand hygiene arrangement according to claim 1 , wherein downstream of the common disposal opening a separator device for separating solids and fluids is provided.

4. The hand hygiene arrangement according to claim 3 , wherein the separator device is a double-walled pipe line,
wherein an intermediate space is defined between an inner pipe, which is connected to the common disposal opening, and an outer pipe, and
wherein the inner pipe comprises a plurality of holes and an inner space created by the inner pipe is connected to the intermediate space through the plurality of holes.

5. The hand hygiene arrangement according to claim 4 , wherein the separator device comprises at least one directional change along the flow direction in form of a curvature, in order to exert a centrifugal force on the mixture that flows through, with which fluid contained in the mixture enters the intermediate space through the openings in order to be dischargeable separately.

6. The hand hygiene arrangement according to claim 1 , wherein the hand receiving region comprises a hand receiving opening, which is configured as an air supply device, and
wherein a negative pressure is generatable at the negative pressure device, such that ambient air is suctionable and that the stream of air is generatable in the hand receiving region for drying hands.

7. The hand hygiene device according to claim 1 , wherein the washing device comprises a water discharge device, and
wherein the discharged water is configured to be conducted through the basin device and the common disposal opening to the water discharge device.

8. The hand hygiene arrangement according to claim 1 , wherein the negative pressure device is connected to the common disposal opening to dispose of the collected water and solids and to generate the stream of air.

9. The hand hygiene arrangement according to claim 1 , wherein the basin device is has a circumferential water spray device at least partially in an upper edge region of the basin device as a secondary water supply for spraying water from the edge region into the center of the basin device in form of a plurality of spray jets.

10. A sanitary module for a vehicle, the sanitary module comprising:
at least one sanitary function element selected from the group consisting of: toilet, bidet, shower, washbasin and diaper changing table; and
a hand hygiene arrangement comprising:
a washing device;
a basin device; and
a drying device;
wherein the washing device comprises a water supply device for a hand washing process and a spray nozzle,
wherein the drying device comprises an air discharge device for a hand drying process for generating a stream of air for the hand drying process,
wherein the arrangement comprises a hand receiving region, wherein the stream of air is generatable in the hand receiving region,
wherein the air discharge device is connected to the hand receiving region and wherein the arrangement comprises a negative pressure device, which is connected to the air discharge device, wherein the stream of air for the hand drying process is generatable by the negative pressure device,
wherein the basin device comprises the hand receiving region and a water collecting region comprising a discharge opening in communication with the negative pressure device,
wherein the discharge opening is configured to permit an unobstructed passage between the basin device and the negative pressure device;
wherein the spray nozzle is arranged above the basin device and the hand receiving region;
wherein the air discharge device is connected to the discharge opening of the basin device such that air and fluids are discharged via the discharge opening, which forms a common disposal opening, and
wherein the negative pressure device is configured for suctioning solids thrown into the water collecting region, besides fluids, for disposal over the common disposal opening.

11. The sanitary module according to claim 10 , wherein the negative pressure device is configured for suctioning paper towels thrown into the basin device for a disposal over the common disposal opening.

12. The sanitary module according to claim 10 , wherein downstream of the common disposal opening a separator device for separating solids and fluids is provided.

13. The sanitary module according to claim 12 , wherein the separator device is a double-walled pipe line,
wherein an intermediate space is defined between an inner pipe, which is connected to the common disposal opening, and an outer pipe, and
wherein the inner pipe comprises a plurality of holes and an inner space created by the inner pipe is connected to the intermediate space through the plurality of holes.

14. The sanitary module according to claim 13 , wherein the separator device comprises at least one directional change along the flow direction in form of a curvature, in order to exert a centrifugal force on the mixture that flows through, with which fluid contained in the mixture enters the intermediate space through the openings in order to be dischargeable separately.
