Abstract
A wet-dry vacuum device assembly comprises a housing and a motor-fan assembly mounted in the housing. The motor-fan assembly is arranged to generate an air flow along an airflow path between a dirty air inlet and a clean air exhaust. The wet-dry vacuum device comprises a tank positioned along the airflow path and arranged to capture liquid entrained in the dirty air flow. The wet-dry vacuum device further comprises a removable pump accessory mountable to the housing. The removable pump accessory comprises pump and a fluid inlet in fluid communication with the tank and the pump. A fluid outlet is in fluid communication with the pump and connectable to an exterior hose. The pump is arranged to move captured liquid in the tank from the fluid inlet to the fluid outlet.
Claims20
A wet-dry vacuum device assembly comprising:
- a housing comprising a tank and a lid mountable on the tank via a latch mechanism;
- a motor-fan assembly mounted in the housing and arranged to generate an air flow along an airflow path between a dirty air inlet and a clean air exhaust;
- the tank positioned along the airflow path and arranged to capture liquid entrained in the dirty air flow;
- and
- a removable pump accessory mountable to the housing, the removable pump accessory comprising:
- a frame mountable to the housing;
- a pump;
- a fluid inlet in fluid communication with the tank and the pump;
- and
- a fluid outlet in fluid communication with the pump and connectable to an exterior hose;
- wherein the pump is arranged to move captured liquid in the tank from the fluid inlet to the fluid outlet;
- wherein when the removable pump accessory is not mounted to the housing, the latch mechanism couples the lid to the tank, and when the removable pump accessory is mounted to the housing, the latch mechanism couples the tank to the frame such that at least a portion of the frame is sandwiched between the tank and the lid.
A pump accessory for a wet-dry vacuum device, the pump accessory being removably mountable to a housing of the wet-dry vacuum device, the pump accessory comprising:
- a frame mountable to the housing of the wet-dry vacuum device;
- a pump;
- a fluid inlet in fluid communication with a tank of the wet-dry vacuum device arranged to capture liquid entrained in a dirty air flow and the pump;
- a fluid outlet in fluid communication with the pump and connectable to an exterior hose;
- wherein the pump is arranged to move captured liquid in the tank from the fluid inlet to the fluid outlet;
- and
- wherein the frame includes a third latch member that is configured to be latched by at least one of a first latch member on the tank and a second latch member on the lid that otherwise directly engage each other to couple the tank and the lid when the frame is removed from the wet-dry vacuum device.
A wet-dry vacuum device assembly comprising:
- a housing comprising a tank and a lid mountable on the tank via a latch mechanism that includes a first latch member coupled to the tank and a second latch member coupled to the lid;
- a motor-fan assembly mounted in the housing and arranged to generate an air flow along an airflow path between a dirty air inlet and a clean air exhaust;
- the tank positioned along the airflow path and arranged to capture liquid entrained in the dirty air flow;
- and
- a removable pump accessory mountable to the housing, the removable pump accessory comprising:
- a frame mountable to the housing;
- a third latch member coupled to the frame;
- a pump;
- a fluid inlet in fluid communication with the tank and the pump;
- a fluid outlet in fluid communication with the pump and connectable to an exterior hose;
- wherein the pump is arranged to move captured liquid in the tank along a liquid flow path from the fluid inlet to the fluid outlet;
- and
- wherein when the removable pump accessory is not mounted to the housing, the first latch member engages the second latch member to couple the lid to the tank, and when the removable pump accessory is mounted to the housing, at least one of the first latch member or the second latch member engages the third latch member such that at least a portion of the frame is mounted between the tank and the lid.
