An air conditioner of the present disclosure includes a base case configured to include a suction port through which air is sucked and accommodate a filter therein, a tower case configured to be disposed above the base case and to include a discharge port through which the air sucked from the suction port is discharged, and a heater configured to be disposed inside the tower case to heat the air.

The subject matter relates to filtered fan hoods and related systems. In one example, a filtered fan hood is provided. The filtered fan hood includes a housing including at least an ambient side and two lateral sides having opposing faces; and a series of staggered baffles secured about the opposing faces such that each baffle in the series of staggered baffles is seated against, alternately, an enclosure side and an ambient side of the housing; whereby an airflow circuit is established by the series of staggered baffles.

The present invention is a transfer or drainage pump, comprising an engine, usually electric, contained in a sealed body, that powers a turbine; said turbine sucks liquid that is close to the suction nozzle, and said liquid is expelled through an outlet duct. The pump includes an external casing with a top lid, a bottom lid and a wall that surrounds the pump, and includes a set of small holes extending over the inferior area of its surface, near the suction nozzle, and a set of bigger holes extending over the superior area of the casing. The present invention also includes a set of space maintainer appliances for the detachment of textile products, sanitary towels, towels, rags that are objects that produce the greater damage to submersible pumps due to the obstruction they can provoke.

A self-propelling watercraft system is provided. The watercraft has a base with a plurality of sidewalls extending from the base to form a cockpit. The base also has a recess, where a pump can detachably connect to the hull within the recess. The pump has an intake valve on a first end and a nozzle on a second end that is opposite the first end. The intake valve can intake water. The nozzle can jettison water received in the pump from the intake valve and agitate water surrounding the nozzle.

A multiport pump and adapter kit for use with a water circulation system for a body of water includes a centrifugal pump assembly having a plurality of outlet ports oriented in different directions and at least one adapter having a first open end configured and dimensioned to be removably connectable to one of said outlet ports, a second open end configured and dimensioned to be removably connectable to a water circulation system, and a hollow body connecting the first open end and the second open end.

First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.

A blower includes a fan and a motor, wherein the motor includes a shaft, a bearing that supports the shaft, and a motor case that covers at least a part of the bearing, the fan includes a main plate having a first surface facing the motor case and a second surface opposite to the first surface, and connected to the shaft, and a plurality of blades erected on the second surface of the main plate, and arranged radially with respect to an axis of the shaft, at least one of the fan and the motor case includes blocking members, and each of the blocking members is located apart from the shaft between the first surface of the main plate and the motor case, and surrounds the shaft.

Provided is a fan, which comprises a body, the body comprises a first air inlet, a second air inletan air outlet, and a fan motor for generating an air flow passing through the body, wherein the first air inlet and the second air inlet are arranged at interval in a first direction; a nozzle, which is connected with the air outlet and used for receiving the air flow from the body and ejecting the air flow; and a filter, which is arranged in a region between the first air inlet and the second air inlet, in the body, and disposed downstream of the air inlet. The fan makes the air pass through the filter more evenly, prolongs the life of the filter, reduces filter replacements, reduces the cost of the air purifier, and is more conducive to the improvement of the indoor environment and provides a cleaner living environment.

The present invention relates to a fruit or vegetable shaped fan for dispersing airborne eye irritants that are released during cutting fruits or vegetables. The fan includes a base that is wedge-shaped, an air inflow collimator that is fruit or vegetable shaped having an open front end, an internal frame that is configured to provide minimal abatement to airflow through the air inflow collimator, a motor mount that secures a motor, a fan blade that attaches to the motor, and a grill that attaches to the open front end of the air inflow collimator. The fan is configured to disperse airborne eye irritants away from a user's eyes. Airborne eye irritants are released when certain fruits and vegetables are chopped or otherwise cut. Such fruits and vegetables that can release airborne eye irritants when cut include onions, peppers, and certain other fruits and vegetables.

An attachable air filter medium for attachment to a conventional circulation fan is disclosed comprising a netting fabric filter medium being adapted to fit over the rear half of the conventional circulation fan's housing for filtering dust particles in air coming into the circulation fan preventing dust buildup on the fan blade thus eliminate the need to periodically clean the fan.
