Abstract
A wash liquid inlet nozzle is provided for directing wash liquid against a bottom wall and a side wall of a vertical axis basket of an automatic washer. The inlet nozzle has a body with a rear wall, a front wall and a top wall connecting the rear wall and front wall. An inlet passage extends through the rear wall for directing a flow of wash liquid into the inlet nozzle. The front wall is arranged and configured in a first area to direct wash liquid against the basket bottom wall and a lower region of the basket side wall and in a second area to direct wash liquid against a middle and an upper region of the basket side wall. With such an inlet nozzle, wash liquid is directed in a sheet against the entire height of the basket wall to wet all of the clothes in the basket.
Claims23
A wash liquid inlet nozzle for directing wash liquid against a bottom wall and a side wall of a vertical axis basket of an automatic washer, said inlet nozzle comprising:
- a body having a rear wall, a front wall and a top wall connecting said rear wall and front wall;
- an inlet passage extending through said rear wall for directing a flow of wash liquid into said inlet nozzle;
- said front wall being arranged and configured in a first area to direct wash liquid against said basket bottom wall and a lower region of said basket side wall and in a second area to direct wash liquid against a middle and an upper region of said basket side wall.
A wash liquid inlet nozzle for directing wash liquid into a vertical axis basket, having a sidewall and a bottom wall, of an automatic washer, said inlet nozzle comprising
- a body having a rear wall, two side walls, a front wall and a top wall connecting said rear wall, side walls and front wall, with an open bottom;
- an inlet passage extending through said rear wall for directing a flow of wash liquid into said inlet nozzle;
- said front wall having a first linear segment, a second linear segment and a radius segment;
- said first linear segment being arranged to be perpendicular to a front-to-rear axis of said washer;
- said second linear segment arranged at about a 45 degree angle to said first linear segment;
- said radius segment connecting said first linear segment and said second linear segment;
- said inlet passage defining an inlet axis, said inlet axis being arranged at an angle of about 13 to 17 degrees to said front-to-rear axis,
- said body being positioned to one side of said front-to-rear axis, such that said first linear segment is positioned away from said front-to-rear axis relative to said second linear segment;
- said front wall at said first linear segment being angled downwardly and toward said basket and away from vertical at an angle of approximately 12 to 16 degrees;
- said front wall at said second linear segment being angled downwardly and toward said basket and away from vertical at an angle of approximately 12 to 16 degrees:
- said top wall being arranged at a downward and forward angle of approximately 15 to 19 degrees relative to said inlet axis;
- whereby, said wash liquid entering said body along said inlet axis will impinge on said top wall to fan out laterally towards said side walls as it travels towards said front wall, and as it strikes said front wall, being redirected downwardly and towards said basket wall, with a first portion of said wash liquid which strikes said first linear segment being directed to a bottom of said basket and a lower region of said basket side wall, a second portion of said wash liquid which strikes said second linear segment being directed to a middle and upper region of said basket side wall, and a third portion of said wash liquid which strikes said radius segment connecting said first portion and said second portion into a continuous sheet.
A method for directing wash liquid against a bottom wall and a side wall of a vertical axis basket of an automatic washer, comprising the steps of:
- providing a body having a rear wall, a front wall and a top wall connecting said rear wall and front wall;
- providing an inlet passage extending through said rear wall for directing a flow of wash liquid into said inlet nozzle;
- arranging and configuring a first segment of said front wall to direct wash liquid against said basket bottom wall and a lower region of said basket side wall;
- arranging and configuring a second segment of said front wall to direct wash liquid against a middle and an upper region of said basket side wall;
- directing wash liquid in through said inlet passage against said front wall, such that a portion of said wash liquid striking said first segment of said front wall will be redirected against said basket bottom wall and a lower region of said basket side wall and a portion of said wash liquid striking said second segment of said front wall will be redirected against said middle and said upper region of said basket wall.
