Motor cover for wet/dry vacuum cleaner with vent openings

A vacuum cleaner comprising:

• a canister defining a debris chamber;
• a lid mounted to a top of the canister and enclosing the debris chamber;
• a motor cover connected to the lid and defining a motor cavity;
• a motor connectable to a power source and enclosed within the motor cavity;
• and
• an impeller connected to the motor and operable to generate air flow through the debris chamber upon operation of the motor;
• wherein the motor cover includes a lattice structure defining a plurality of vent openings that provide ventilation of the motor cover, wherein each vent opening of the plurality of vent openings is defined by a first cross member, a second cross member, a first side member, and a second side member of the lattice structure, wherein the second cross member is spaced vertically below the first cross member and the first side member is spaced horizontally forward from the second side member, each of the first and second side members extending from the first cross member to the second cross member, wherein the second cross member extends further outward from a central vertical axis of the motor cover than the first cross member, wherein the first side member extends further outward from the central longitudinal axis than the second side member, and wherein the first cross member and the second cross member slope downward at an oblique angle θs relative to a horizontal plane oriented perpendicular to the central vertical axis of the motor cover.

A power head for a vacuum cleaner, the power head comprising:

• a motor cover defining a motor cavity;
• a motor connectable to a power source and enclosed within the motor cavity;
• and
• an impeller connected to the motor and operable to generate air flow upon operation of the motor;
• wherein the motor cover includes a lattice structure defining a plurality of vent openings that provide ventilation of the motor cover, wherein each vent opening of the plurality of vent openings is defined by a first cross member, a second cross member, a first side member, and a second side member of the lattice structure, wherein the second cross member is spaced vertically below the first cross member and the first side member is spaced horizontally forward from the second side member, each of the first and second side members extending from the first cross member to the second cross member, wherein the second cross member extends further outward from a central vertical axis of the motor cover than the first cross member, wherein the first side member extends further outward from the central longitudinal axis than the second side member, and wherein the first cross member and the second cross member slope downward at an oblique angle θs relative to a horizontal plane oriented perpendicular to the central vertical axis of the motor cover.
