Abstract

A washing machine having a chemical dispenser for dispensing chemicals into the wash water during a washing operation. The dispenser includes a dispenser body having a water inlet and a cap having a plurality of hose connecting ports to which chemical supply hoses are individually attached for enabling the direction of chemical into the dispenser chamber simultaneous with the introduction of water from the water inlet. The chemical supply hoses are connectable to the cap at a location remote from said body, and the cap is removable and replaceable in said dispenser body without removal of the hose from the connecting ports.

Claims

1. A washing machine comprising:

an outer cabinet,

a wash tub disposed within said cabinet for receiving wash water during a washing operation,

a rotatably driven tumbler for receiving launderable items for washing supported within said wash tub,

a plurality of sources of different laundry chemicals located outside said cabinet for use during washing operations,

a chemical dispenser connected to said plurality of sources of different laundry chemicals by a plurality of respective chemical supply hoses,

said dispenser including a dispenser body mounted within said cabinet that defines a chamber into which laundry chemicals and water are directed and an outlet connected to and communicating with the wash tub, said dispenser body having a chemical inlet hub disposed in an opening of said cabinet and protruding outwardly from said cabinet for directing chemicals into said chamber,

said dispenser including a hose connection cap separate from said dispenser body,

said cap having a base and a plurality of integrally formed hose connecting ports extending outwardly of said base communicating through said cap,

said chemical supply hoses each being connected to a respective one of said connecting ports for permitting selected dispensing of laundry chemicals from said hoses into said chamber for direction through said outlet to said wash tub during a washing operation,

and said cap being mountably supported by an outer end of said hub without protruding into said chamber and being removable and replaceable on said hub without removal of said dispenser body from said cabinet and without removal of said hoses from said connecting ports.

2. The washing machine of claim 1 in which said hoses are connectable to said cap while said cap is removed from said dispenser.

3. The washing machine of claim 1 in which said hose connection cap and dispenser body are made of plastic material, and said hose connection cap is made of a plastic material different from the plastic material of said dispenser body so that they have different durability and corrosion-resistant characteristics.

4. The washing machine of claim 1 in which said cap and dispenser body have a releasable latching mechanism for enabling removable snap action engagement of the cap with said body.

5. The washing machine of claim 4 in which said cap has latch arms that are releasably engageable with said dispenser body.

6. The washing machine of claim 1 in which said cap is removably mountable in recessed relation in said hub.

7. The washing machine of claim 6 in which said cap is mountable in said hub with said hose connecting ports having terminal ends that extend outwardly no greater than an outer perimeter of said hub.

8. The washing machine of claim 6 in which said hub of said dispenser inlet hub extends outwardly of said outer cabinet at an acute angle to the vertical, and said cap is removably mountable in an outer end of said hub.

9. The washing machine of claim 8 in which said dispenser body has a water inlet connectable to a water supply hose for directing water into said body chamber simultaneously with the direction of laundry chemicals from said hose connecting ports.

10. The washing machine of claim 9 in which said water inlet is at an upper end of said dispenser body.

11. The washing machine of claim 10 in which said dispenser body has an upstanding portion that defines said dispensing chamber, and said hub communicates with said chamber through a side opening of said upstanding portion.

12. The washing machine of claim 11 in which said dispenser body has a central downwardly directed diverter wall adjacent an upper portion of said side opening in opposing relation to the water inlet for diverting water about opposite sides of said side opening.

13. The washing machine of claim 1 in which said dispenser body and cap have at least one cooperating key and key way for orienting said cap in predetermined circumferential relation to said hub upon mounting.

14. A washing machine comprising:

an outer cabinet,

a wash tub disposed within said cabinet for receiving wash water during a washing operation,

a rotatably driven tumbler for receiving launderable items for washing supported within said wash tub,

a plurality of sources of different laundry chemicals located outside said cabinet for use during washing operations,

a chemical dispenser connected to said plurality of sources of different laundry chemicals by a plurality of respective chemical supply hoses,

said dispenser including a dispenser body that defines a chamber into which laundry chemicals and water are directed and an outlet connected to and communicating with the wash tub,

said dispenser including a hose connection cap separate from said dispenser body having a plurality of hose connecting ports communicating through the cap,

said chemical supply hoses each being connected to a respective one of said connecting ports for permitting selected dispensing of laundry chemicals from said hoses into said chamber for direction through said outlet to said wash tub during a washing operation,

said dispenser having a cap receiving hub extending outwardly at an acute angle to the vertical, said cap being removably mountable in recessed relation in an outer end of said hub,

said cap being removable and replaceable on said hub without removal of said hoses from said connecting ports,

said dispenser body having a water inlet at an upper end of said dispenser connectable to a water supply hose for directing water into said body chamber simultaneously with the direction of laundry chemicals from said hose connecting ports,

said dispenser body having an upstanding portion that defines said dispensing chamber, said hub communicating with said chamber through a side opening of said upstanding portion, and

a wall extending upwardly from a lower portion of said hub for defining a pocket into which laundry chemicals and water directed into said dispenser may accumulate.

15. A washing machine comprising:

an outer cabinet,

a wash tub disposed within said cabinet for receiving wash water during a washing operation,

a rotatably driven tumbler for receiving launderable items for washing supported within said wash tub,

a plurality of sources of different laundry chemicals located outside said cabinet for use during washing operations,

a chemical dispenser connected to said plurality of sources of different laundry chemicals by a plurality of respective chemical supply hoses,

said dispenser including a dispenser body that defines a chamber into which laundry chemicals and water are directed and an outlet connected to and communicating with the wash tub,

said dispenser including a hose connection cap separate from said dispenser body having a plurality of hose connecting ports communicating through the cap,

said chemical supply hoses each being connected to a respective one of said connecting ports for permitting selected dispensing of laundry chemicals from said hoses into said chamber for direction through said outlet to said wash tub during a washing operation,

said dispenser having a cap receiving hub extending outwardly at an acute angle to the vertical, said cap being removably mountable in recessed relation in an outer end of said hub,

said cap being removable and replaceable on said hub without removal of said hoses from said connecting ports,

said dispenser body having a water inlet at an upper end connectable to a water supply hose for directing water into said body chamber simultaneously with the direction of laundry chemicals from said hose connecting ports,

said dispenser body having an upstanding portion that defines said dispensing chamber, said hub communicating with said chamber through a side opening of said upstanding portion, and

said dispenser body having a V-shaped diverter with an apex in opposed relation to said water inlet for dividing water directed into said chamber toward opposite sides of the chamber.
