Abstract

A water-conducting household machine, specifically a dishwasher, includes a compartment having a closable compartment opening, and at least one washing device for generating at least one water jet in the compartment. At least one baffle plate is disposed on an inner side of the compartment in at least one area of impact of the water jet and in such a way as to be vibration-free for noise reduction, particularly for noise damping and/or sound insulation.

Claims (19)

1. A water-conducting household appliance, comprising:

a compartment having a closable compartment opening;

at least one washing device for generating at least one water jet in the compartment, and

at least one baffle plate disposed on an inner side of the compartment in at least one area of impact of the water jet so that the baffle plate does not vibrate when impacted by the water jet, and

a spring damper system that connects the baffle to compartment.

2. The water-conducting household appliance of claim 1 , constructed in the form of a dishwasher.

3. The water-conducting household appliance of claim 1 , wherein the baffle plate is constructed for noise damping and/or sound insulation.

4. The water-conducting household appliance of claim 1 , further comprising a spring damper system to realize a disposition of the at least one baffle plate in a vibration-free manner.

5. The water-conducting household appliance of claim 4 , wherein the spring damper system includes an intermediate piece made of a vibration-decoupling and/or vibration-damping material.

6. The water-conducting household appliance of claim 1 , wherein the baffle plate is disposed on at least one member of the compartment selected from the group consisting of a side wall, a roof, and floor.

7. The water-conducting household appliance of claim 1 , further comprising a plurality of said at least one baffle plate for disposition on at least one member of the compartment selected from the group consisting of a side wall, a roof, and floor.

8. The water-conducting household appliance of claim 1 , further comprising a plurality of water jets and a plurality of baffle plates, wherein the baffle plates extend over an entire area that the water jets impact.

9. The water-conducting household appliance of claim 1 , wherein the baffle plate is made of a material with a damping property higher than a damping property of a material used to form the compartment.

10. The water-conducting household appliance of claim 1 , wherein the spring damper system comprises an intermediate piece made of a vibration-decoupling and/or vibration-damping material.

11. The water-conducting household appliance of claim 1 , wherein the baffle plate comprises a surface structure adapted to insulate and/or dampen sound.

12. The water-conducting household appliance of claim 11 , wherein the surface structure comprises ribs.

13. The water-conducting household appliance of claim 11 , wherein the surface structure is adapted such that the water jet strikes the surface structure at an angle less than 90°.

14. The water-conducting household appliance of claim 11 , wherein the surface structure is adapted such that the water jet strikes the surface structure at an angle less than 90°.

15. The water-conducting household appliance of claim 1 , further comprising a plurality of said at least one baffle plate disposed on at least one member of the compartment selected from the group consisting of a side wall, a roof, and floor.
