Plastic liquor container for a washing machine or a clothes dryer, and method for the production of a liquor container

1. A plastic liquor container for a washing machine, the plastic liquor container comprising:

a rear wall made of at least two plastic components having different strengths, the rear wall having reinforced regions and a bearing receptacle for a shaft journal of a laundry drum, the bearing receptacle being made of a high-strength material; wherein

the rear wall is manufactured as a single piece by injecting the at least two plastic components into an injection molding mold with a time offset;

the reinforced regions of the rear wall are structured as a sandwich component having an inner edge layer and an outer edge layer;

the inner edge layer and the outer edge layer of the sandwich component are made of respective high-strength plastic and enclose a region made of plastic that is less strong than the respective high-strength plastic; and

the plastic that is less strong extends radially away from the bearing receptacle farther than the high-strength plastic.

2. The plastic liquor container of claim 1 , further comprising a drum jacket, wherein, in a region of the bearing receptacle, a proportion of the high-strength plastic is of a predetermined amount, and wherein the proportion decreases outward toward the drum jacket.

3. The plastic liquor container of claim 1 , wherein the inner edge layer forms a front-most outer surface of the rear wall and the outer edge layer forms a rear-most outer surface of the rear wall.

4. The plastic liquor container of claim 1 , wherein the high-strength material includes reinforcement from glass fibers that are injected into the rear wall.

5. The plastic liquor container of claim 1 , wherein the inner edge layer and the outer edge layer decrease in thickness in a radially outward direction.

6. A method for producing a plastic liquor container for a washing machine, the plastic liquor container having a rear wall made of at least two plastic components having different strengths, the rear wall having a bearing receptacle for a shaft journal of a laundry drum, wherein the bearing receptacle is made of a high-strength material, the method comprising:

manufacturing the rear wall as a single piece by injecting, with a time offset, the at least two different plastic components into an injection molding mold for producing the plastic liquor container; wherein

a high-strength plastic component is introduced at a start of injection;

a plastic component that is less strong than the high-strength plastic component is introduced after the high-strength plastic component is introduced and thus forming a sandwich component having an inner edge layer and an outer edge layer where the high-strength plastic encloses the plastic that is less strong; and

the plastic that is less strong is extended radially away from the bearing receptacle farther than the high-strength plastic.

7. The method of claim 6 , wherein respective quantities of the high-strength plastic component and the plastic component that is less strong than the high-strength plastic component that are introduced per unit of time can be controlled.

8. The method of claim 6 , wherein respective quantities of the high-strength plastic component and the plastic component that is less strong than the high-strength plastic component are injected with an even distribution and symmetrically in relation to a drum axis.

9. A plastic liquor container for a washing machine, the plastic liquor container comprising:

a rear wall with reinforced regions; and

a bearing receptacle for a shaft journal of a laundry drum, wherein

the rear wall comprises a rear outer-most layer, a front outer-most layer and an intermediate layer between the rear outer-most layer and the front outer-most layer,

the rear outer-most layer and the front outer-most layer are made from a first plastic injection molded material,

the intermediate layer is made from a second plastic injection molded material,

the first plastic injection molded material is stronger than the second plastic injection molded material, and

the second plastic injection molded material extends radially away from the bearing receptacle farther than the first plastic injection molded material.

10. The plastic liquor container according to claim 9 , wherein the rear outer-most layer, the front outer-most layer and the intermediate layer are unified in a single piece by an injection molding process.

11. The plastic liquor container according to claim 9 , wherein the intermediate layer is injected between the rear outer-most layer and the front outer-most layer.

12. The plastic liquor container of claim 9 , further comprising a drum jacket,

wherein the drum jacket is formed from the second plastic injection molded material and continuously with the intermediate layer.

13. The plastic liquor container of claim 9 , wherein

an axial thickness of the rear wall in a region nearest the bearing receptacle comprises the first plastic injection molded material but not the second plastic injection molded material, and

the axial thickness outside of a predetermined radius from the bearing receptacle comprises the second plastic injection molded material but not the first plastic injection molded material.

14. The plastic liquor container of claim 9 , wherein the first plastic injection molded material includes glass fiber reinforcement.

15. The plastic liquor container of claim 9 , wherein the second plastic injection molded material includes talc reinforcement.

16. The plastic liquor container of claim 9 , wherein the second plastic injection molded material is injected with a time offset with respect to the first plastic injection molded material.

17. The plastic liquor container of claim 9 , wherein the rear outer-most layer and the front outer-most layer decrease in thickness in a radially outward direction.
