Abstract
The invention relates to a device for cleaning an immersed surface including a body and members for driving the body over the immersed surface; a filtration chamber which is provided in the body and which has: a liquid inlet; a liquid outlet; a hydraulic circuit for the flow of liquid between the inlet and the outlet through a filtering device, wherein the filtering device includes a filtering casing which is removably mounted in the filtration chamber and which can be inserted into and removed from the filtration chamber in one piece, and the filtering casing has at least a lower end which opens at the base of the body and which constitutes a liquid inlet into the body of the device.
Claims9
A swimming pool cleaner comprising:
- a. a body (i) defining a water inlet and a water outlet and (ii) configured for movement within a swimming pool;
- and
- b. a debris filter defining a debris recovery space and comprising:
- i. a transverse separation wall configured to prevent debris entering the debris recovery space from exiting the water inlet when the swimming pool cleaner is in use;
- ii. an upper filtering wall;
- iii. an inclined lower filtering wall;
- iv. a rear extreme curved portion connecting the upper filtering wall and the inclined lower filtering wall;
- and
- v. first and second lateral walls connecting the upper filtering wall and the inclined lower filtering wall.
A swimming pool cleaner comprising;
- a. a body (i) defining a water inlet and a water outlet and (ii) configured for movement within a swimming pool;
- b. a pumping propeller positioned at least partially within the body;
- and
- c. a debris filter defining a debris recovery space and comprising:
- i. a transverse separation wall configured to prevent debris entering the debris recovery space from exiting the water inlet when the swimming pool cleaner is in use;
- ii. an upper filtering wall;
- iii. an inclined lower filtering wall;
- iv. a rear extreme curved portion connecting the upper filtering wall and the inclined lower filtering wall;
- and
- v. first and second lateral walls connecting the upper filtering wall and the inclined lower filtering wall;
- and
- in which (a) the transverse separation wall is immobile relative to the body when the pumping propeller is operating and (b) the body lacks any water non-return valve.
A swimming pool cleaner comprising:
- a. a body (i) defining a water inlet and a water outlet and (ii) configured for movement within a swimming pool;
- and
- b. a debris filter defining debris recovery space and comprising:
- i. a transverse separation wall configured to prevent debris entering the debris recovery space from exiting the water inlet when the swimming pool cleaner is in use;
- ii. an upper filtering wall;
- iii. an inclined lower filtering wall;
- iv. a rear extreme curved portion connecting the upper filtering wall and the inclined lower filtering wall;
- and
- v. first and second lateral walls connecting the upper filtering wall and the inclined lower filtering wall;
- and
- in which (a) the transverse separation wall forms part of a second shell and (b) the upper filtering wall, inclined lower filtering wall, rear extreme curved portion, and first and second lateral walls form at least part of a first shell configured to attachment to the second shell, the first and second shells being completely separable to expose the debris recovery space.
