In another embodiment, the coupling 45 may be carried by the drawer 32, and may be fluidly connected to the cartridge 40 when the drawer 32 slides into the cabinet 22.
The rear wall 60 of the cartridge recess 46 may include a support boss 53 which may be used to dock an outlet portion of the cartridge 40 such that the cartridge 40 may be properly positioned in the drawer 32. The support boss 53 is aligned with the coupling 45 within the cabinet 22, such that when the drawer 32 is in the closed position, the outlet portion of the cartridge 40 may be coupled with the coupler 45.
Referring back to FIG. 2, the drawer 32 may have at least one of an offset area 48 and a relief area 50 adjacent the cartridge recess 46 to enable a user to grasp the cartridge 40 for removal. In the illustrated embodiment the drawer 32 is provided with one offset area 48 and one relief area 50. However, it is within the scope of the invention for the drawer 32 to be provided with other numbers and/or combinations of offset and relief areas 48, 50.
The offset area 48 may be formed by an inset or laterally-recessed portion 61 of the first side wall 54. The recessed portion creates a space or gap 56 between the first side wall 54 and the cartridge 40, when the cartridge 40 is recessed by the cartridge recess 46. The offset area 48 may permit a user to insert one or more fingers into the gap 56 between the first side wall and the cartridge 40 to remove the cartridge 40 from the cartridge recess 46.
The relief area 50 may be formed by a reduced-height portion 51 of the second side wall 55. The reduced-height portion 51 may be reduced in height in comparison to the cartridge 40 in the cartridge recess 46. As illustrated, the reduced-height portion 51 may extend substantially along the second side wall 55, and may further be reduced in height as compared with any or all of the front, rear, and first side walls 54. It is noted that the front, rear, and first side walls 54 of the cartridge recess 46 may be configured to have the same or a greater height in comparison to the cartridge 40 in the cartridge recess 46. The relief area 50 may permit a portion of the cartridge 40 to be exposed within the cartridge recess 46 to facilitate gripping of the cartridge 40 when removing the cartridge 40 from the cartridge recess 46.
As is shown in the illustrated embodiment, the offset and relief areas 48, 50 may advantageously be provided on opposing sides of the cartridge recess 46 to facilitate gripping the cartridge 40 on opposite sides with a single hand during removal. According to one potential gripping configuration, a user may wrap a single hand around the cartridge 40, with one or more fingers of the hand engaging the cartridge 40 via insertion into the offset area 48 and the thumb of the hand engaging the cartridge 40 via the reduced height of the relief area 50.
FIG. 4 is a side view of the drawer 32 of the dispensing system 12. As illustrated, the bottom wall 52 of the cartridge recess 46 may be sloped relative to a horizontal plane; phantom line A illustrates the general shape of the angled bottom wall 52 without the aperture 44. When the cartridge 40 (shown in phantom) is received by the drawer 32, the cartridge includes a lower surface B, which also may be sloped relative to the horizontal plane, while an upper surface C of the cartridge may be generally parallel to the horizontal plane. In yet another embodiment, the cartridge 40 may include flat bottom surface, with the cartridge 40 may have an angled bottom portion that is viewable through the aperture 44 in the drawer 32.
The bottom wall 52 may include a lower surface 57 on which a graduated scale 66 may by provided for indicating the presence and/or amount of treating chemistry in the cartridge 40. As illustrated, the graduated scale 66 may be provided adjacent the aperture 44. When used with a translucent or transparent cartridge 40, the present of treating chemistry in the cartridge 40 can be determined, and the graduated scale 66 can be used to determine how much treating chemistry is available. The graduated scale 66 may be formed on the drawer 32 by an engraving or printing process. While shown as being provided on the drawer 32, the graduated scale 66 may be alternatively provided on the cartridge 40 such that the graduated scale 66 may be visible through the aperture 44 when the cartridge 40 is received by the drawer 32.
FIG. 5 is a bottom perspective view of the drawer 32 of the dispensing system 12, with the cartridge 40 of treating chemistry disposed inside the drawer 32. As shown, with the drawer 32 in the open position, a portion of the aperture 44 is exterior of the cabinet 22, such that the cartridge 40 is viewable through the aperture 44 when the drawer 32 is viewed from below. This configuration has the benefit of providing visual confirmation to the user that the cartridge 40 is installed in the drawer 32, and will also provide visual confirmation when a cartridge is not installed. This is especially beneficial when employed with the stacked modular laundry system 10 of FIG. 1. In this case, while it may be relatively easy to view the top side of the dispensing system 12 of the lower laundry treating appliance 14, it is less easy to view the top side of the dispensing system 12 of the upper laundry treating appliance 16. By providing the aperture 44, the user is able to confirm the presence or absence of the cartridge 40 from beneath the dispensing system 12. The cartridge 40 of treating chemistry may have a light transmitting material such that treating chemistry retained in the cartridge 40 may be viewable through the cartridge 40. Furthermore, by providing the graduated scale 66, the user may be able to determine the amount of treating chemistry within the cartridge 40.
The offset and relief areas 48, 50 provide further benefits to the dispensing system 12. Effectively, the offset and relief areas 48, 50 provide increased accessibility to a cartridge within a dispensing system 12, while maintaining a secure fit between the cartridge 40 and the drawer 32. The offset and relief areas 48, 50 permit the user to remove or insert the cartridge 40 with a single hand. Furthermore, when employed with the stacked modular laundry system 10 of FIG. 1, the offset and relief areas 48, 50 may provide tactile feedback to the user when inserting or removing the cartridge 40 into or from the drawer 32.
While the invention has been specifically described in connection with certain specific embodiments thereof, it is to be understood that this is by way of illustration and not of limitation. Reasonable variation and modification are possible within the scope of the forgoing disclosure and drawings without departing from the spirit of the invention which is defined in the appended claims.
