Abstract

Automatic swimming pool cleaners (APCs) may include separate chassis and bodies. Such constructions may facilitate assembly and disassembly of certain components of the APCs, with or without using tools. APCs with separate chassis and bodies may enable quick and easy access to motor assemblies of the APC, and bodies of the APCs may be readily interchanged on a common chassis.

First claim

That which is claimed is:

1 . An automatic swimming pool cleaner comprising a housing and a chassis, wherein the housing is removably attached to the chassis.

2 . The automatic swimming pool cleaner of claim 1 , wherein the chassis comprises a chassis cavity, wherein the housing comprises a body and an engagement section extending downwardly from the body, and wherein the engagement section of the housing is positionable within the chassis cavity such that the housing is removably attached to the chassis.

3 . The automatic swimming pool cleaner of claim 2 , wherein the chassis further comprises a first engagement feature within the chassis cavity, wherein the housing comprises a second engagement feature on the engagement section that is complimentary to the first engagement feature, and wherein the engagement section of the housing is positionable within the chassis cavity such that the first engagement feature selectively engages the second engagement feature.

4 . The automatic swimming pool cleaner of claim 3 , wherein one of the first engagement feature or the second engagement feature comprises a recess or a first rib, and wherein the other one of the first engagement feature or the second engagement feature comprises a second rib.

5 . The automatic swimming pool cleaner of claim 1 , wherein the chassis comprises a chassis cavity, wherein the housing comprises a housing cavity, and wherein the automatic swimming pool cleaner further comprises a motor block positioned at least partially within the chassis cavity and extending at least partially into the housing cavity.

6 . The automatic swimming pool cleaner of claim 5 , wherein the housing cavity comprises a bottom surface recessed relative to a top end of the housing, wherein the bottom surface defines an aperture, and wherein the motor block extends at least partially through the aperture and into the housing cavity.

7 . The automatic swimming pool cleaner of claim 1 , further comprising:
a motor block positioned at least partially in the chassis; and a flow outlet configured to attach to the motor block such that at least a portion of the housing is retained between the motor block and the flow outlet.

8 . An automatic swimming pool cleaner comprising:
a chassis; a housing; a motor block positioned at least partially in the chassis; and a flow outlet configured to removably attach to the motor block such that at least a portion of the housing is retained between the motor block and the flow outlet.

9 . The automatic swimming pool cleaner of claim 8 , wherein the housing comprises a housing cavity, wherein the motor block extends at least partially into the housing cavity, and wherein the flow outlet is within the housing cavity.

10 . The automatic swimming pool cleaner of claim 8 , wherein the motor block comprises an engagement portion and at least one stopper, and wherein the flow outlet is configured to attach to the engagement portion of the motor block such that the portion of the housing is retained between the flow outlet and the at least one stopper.

11 . The automatic swimming pool cleaner of claim 8 , wherein the housing comprises a housing cavity with a bottom surface that is recessed relative to a top end of the housing, and wherein the flow outlet is configured to attach to the motor block such that a portion of the bottom surface of the housing cavity is retained between the motor block and the flow outlet.

12 . The automatic swimming pool cleaner of claim 8 , wherein the housing comprises a body and an engagement section extending downwardly from the body, and wherein the engagement section of the housing is positionable within the chassis such that the housing is removably attached to the chassis.

13 . The automatic swimming pool cleaner of claim 12 , wherein the chassis comprises a chassis cavity, wherein the motor block is positioned at least partially within the chassis cavity and the engagement section of the housing is positioned at least partially within the chassis cavity, wherein the chassis further comprises a first engagement feature within the chassis cavity, wherein the housing comprises a second engagement feature on the engagement section that is complimentary to the first engagement feature, and wherein the engagement section of the housing is positionable within the chassis cavity such that the first engagement feature selectively engages the second engagement feature.

14 . An automatic swimming pool cleaner comprising:
a chassis comprising a chassis cavity; a housing comprising a housing cavity; and a motor assembly positioned at least partially in the chassis cavity and extending at least partially into the housing cavity.

15 . The automatic swimming pool cleaner of claim 14 , wherein the housing further comprises a lid movable between a closed position and an open position relative to the housing cavity, wherein the lid in the open position provides access to the motor assembly at least partially in the housing cavity.

16 . The automatic swimming pool cleaner of claim 14 , wherein the housing cavity comprises a bottom surface that is recessed relative to a top end of the housing, wherein the bottom surface defines an aperture, and wherein the motor assembly extends at least partially through the aperture and into the housing cavity.

17 . The automatic swimming pool cleaner of claim 16 , further comprising a flow outlet that is configured to attach to the motor assembly within the housing cavity such that at least a portion of the bottom surface of the housing cavity is retained between the motor assembly and the flow outlet.

18 . The automatic swimming pool cleaner of claim 14 , further comprising a flow outlet within the housing cavity and configured to attach to the motor assembly such that at least a portion of the housing is retained between the motor assembly and the flow outlet.

19 . The automatic swimming pool cleaner of claim 14 , wherein the housing further comprises a body and an engagement section extending downwardly from the body, wherein the body defines the housing cavity, and wherein the engagement section of the housing is positionable within the chassis cavity such that the housing is removably attached to the chassis.

20 . The automatic swimming pool cleaner of claim 19 , wherein the chassis further comprises a first engagement feature within the chassis cavity, wherein the housing comprises a second engagement feature on the engagement section that is complimentary to the first engagement feature, and wherein the engagement section of the housing is positionable within the chassis cavity such that the first engagement feature selectively engages the second engagement feature.
