This application claims priority to U.S. Provisional Patent Application No. 63/222,528, filed Jul. 16, 2021, the entire contents of which are hereby incorporated by reference herein.
BACKGROUNDThe present invention relates to surface cleaners, and more particularly, a recovery tank of a wet surface cleaner.
SUMMARYIn one embodiment a surface cleaner is disclosed including a body, a handle positioned on the body, a suction source, and a recovery tank. The suction source is configured to generate a suction airflow along an airpath between a suction inlet and an air exhaust. The recovery tank is along the airpath in communication with the suction inlet and the suction source. The recovery tank has an upper portion including a cover removably connected to the upper portion, a lower portion, and sidewalls connecting the upper portion and the lower portion. The recovery tank has a tank inlet in communication with the suction inlet and an outlet duct within the recovery tank and in communication with the air exhaust. The outlet duct extends from the lower portion toward the upper portion. The cover forms an outlet chamber adjacent the outlet duct when the cover is connected to the recovery tank.
Other aspects of the invention will become apparent by consideration of the detailed description and accompanying drawings.
Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways.
DETAILED DESCRIPTIONThe present disclosure relates to a surface cleaner, specifically a surface cleaner configured to recover and/or distribute cleaning liquid. The surface cleaner includes a recovery tank configured to collect dirt water and debris from a surface to be cleaned. The recovery tank has a cover that is removably connected to an upper portion of the recovery tank. The recovery tank also has an outlet duct that extends form a lower portion of the recovery tank, where the cover forms an outlet chamber over the outlet duct. This arrangement forces air to travel along a path through the recovery tank in order to reach the outlet duct, thus inhibiting liquid entering the outlet duct.
The surface cleaner 10 (
The recovery tank 30 has an upper portion 32, a lower portion 34, and side walls 36 connecting the upper portion 32 and the lower portion 34. The recovery tank 30 has a cover 50 removably connected to the upper portion 32. The outlet duct 42 is in communication with the air exhaust 24 and the outlet duct 42 extends from the lower portion 34 toward the upper portion 32. The tank outlet 40 is positioned in the upper portion 32. The tank outlet 40 is in the airpath between the recovery tank 30 and the outlet duct 42. The cover 50 forms an outlet chamber 44 adjacent the tank outlet 40 and adjacent at least a portion of the outlet duct 42 when the cover 50 is connected to the recovery tank 36. As illustrated in
In the embodiment illustrated in
In operation, air and fluid enter the recovery tank 30 through the tank inlet 38. The air and fluid travel along the inlet duct 58 and out the tank inlet 38 into the recovery tank 30. The tank inlet 38 is in communication with the suction inlet 18. In the embodiment illustrated in
In the illustrated embodiment, the recovery tank 36 further includes a baffle wall 52 extending from the lower portion 34. The baffle wall 52 is positioned between the tank inlet 38 and the tank outlet 40. The baffle wall 52 creates another barrier between the tank inlet 38 and the tank outlet 40 and helps reduces waves and splashing in the recover tank 30.
In the embodiment illustrated in
In the embodiment illustrated in
In one embodiment, the recovery tank 30 further comprises a front portion 54 and a back portion 56. Where the surface cleaner is an upright cleaner, the front portion 54 is in the direction of forward movement, and the back portion 56 is opposite the direction of forward movement. In the embodiment illustrated in
Various features and advantages of the invention are set forth in the following claims.
Claims
1. A surface cleaner comprising:
