Abstract

The device includes a vessel to be filled with a mixture of water and a component producing foam, where the vessel comprises a device for blowing air into the mixture to produce foam. It is provided according to the disclosure that the device comprises at least two vessels to be filled with the mixture arranged one above the other in a vertical direction in tiers, where the vessels comprise the device for blowing air into the mixture to produce foam, where the vessels are open towards an outlet region such that the foam produced in the vessels is merged in the outlet region.

Claims (34)

1. A device for producing foam for wellness and/or hygiene applications with a vessel to be filled with a mixture of water and a component producing foam, where said vessel comprises:

a plurality of devices for blowing air into said mixture to produce foam,

wherein said device comprises at least two vessels to be filled with said mixture arranged one above the other in a vertical direction in tiers,

where each of said at least two vessels comprises one of said plurality of devices for blowing air into said mixture to produce foam,

where said at least two vessels are open towards an outlet region such that the foam produced in said at least two vessels is merged in said outlet region,

wherein said plurality of devices for blowing air are configured such that the air is introduced from a base of a respective one of said at least two vessels over an area of at least 40% of the base of the respective one of said at least two vessels, and

wherein a tube is connected to said foam outlet opening, where a shower head with a controllable foam outlet is connected to said tube.

2. The device according to claim 1 , wherein said at least two vessels have openings facing said outlet region and a height between the bases of said at least two vessels and upper sides of said at least two vessels increases towards said openings, where said upper sides are formed to be curved.

3. The device according to claim 1 , wherein said blower devices for blowing air in include bubble membranes selected from a group that consists of bubble plates, membranes, or films.

4. The device according to claim 3 , wherein said bubble plates, membranes, or films are configured such that substantially no water and component producing foam can flow back through said bubble plates, membranes, or films when no air is blown in.

5. The device according to claim 1 , wherein said devices for blowing air in comprise a controllable ventilation unit which controls the amount of air introduced into said at least two vessels, where a separate ventilation unit is connected to each vessel.

6. The device according to claim 1 , wherein said at least two vessels are enclosed in a housing which comprises a foam outlet opening from said outlet region.

7. A device for producing foam for wellness and/or hygiene applications with a vessel to be filled with a mixture of water and a component producing foam, wherein said vessel comprises:

a device for blowing air into said mixture to produce foam,

wherein said device comprises at least two vessels to be filled with said mixture arranged one above the other in a vertical direction in tiers,

wherein said at least two vessels comprise said device for blowing air into said mixture to produce foam,

wherein said at least two vessels are open towards an outlet region such that the foam produced in said at least two vessels is merged in said outlet region, and

wherein said at least two vessels are arranged and configured in relation to one another such that water and said component producing foam, which deposit from the foam produced within said device, can flow back into at least one of said at least two vessels so that foam can be produced again with this water.

8. A device for producing foam for wellness and/or hygiene applications with a vessel to be filled with a mixture of water and a component producing foam, where said vessel comprises:

a device for blowing air into said mixture to produce foam,

wherein said device comprises at least two vessels to be filled with said mixture arranged one above the other in a vertical direction in tiers,

where said at least two vessels comprise said device for blowing air into said mixture to produce foam,

where said at least two vessels are open towards an outlet region such that the foam produced in said at least two vessels is merged in said outlet region, and

wherein said the device comprises a water level adjustment system in said at least two vessels.

9. The device according to claim 8 , wherein said water level adjustment system in said at least two vessels is connected to an external water supply and/or a water tank.

10. The device according to claim 9 , wherein said water tank comprises a water temperature control unit and/or a cold pack.

11. The device according to claim 8 , wherein said device comprises a component addition producing foam which is connected to said water level adjustment system.

12. The device according to claim 8 , wherein said device comprises a disinfectant addition which is connected to said water level adjustment system.

13. A device for producing foam for wellness and/or hygiene applications with a vessel to be filled with a mixture of water and a component producing foam, where said vessel comprises:

a device for blowing air into said mixture to produce foam,

wherein said device comprises at least two vessels to be filled with said mixture arranged one above the other in a vertical direction in tiers,

where said at least two vessels comprise said device for blowing air into said mixture to produce foam,

where said at least two vessels are open towards an outlet region such that the foam produced in said at least two vessels is merged in said outlet region, and

wherein said device comprises a battery for operating said device.
