20090004022 | Grille interchanging method and apparatus - According to some embodiments of the invention, an appliance having a removable grille includes: a lip located on the appliance having a hook shape; and a hook shaped end on the grille, the lip and hook shaped end dimensioned to allow the grille to substantially pivot with respect to the appliance when the hook shaped end on the grille and the hook shaped lip are engaged with each other. Other embodiments of the invention include a method of mounting a grille on an appliance including: engaging a hook shaped end of the grille with a lip located on the appliance; moving the grille in a substantially pivoting movement with respect to the appliance; and securing the grille to the appliance. | 01-01-2009 |
20090092499 | Air Inlet Cover - In a first aspect, the present invention provides an air inlet cover ( | 04-09-2009 |
20110236219 | FAN - A portable fan includes a casing having an air inlet and a first connector, and an air outlet having a second connector. A filter unit includes a third connector, which is substantially the same as the second connector, for co-operating with the first connector to removably connect the filter unit to the casing, a filter which is located upstream from the air inlet when the filter unit is connected to the casing, and a fourth connector, which is substantially the same as the first connector, for co-operating with the second connector to removably connect the air outlet to the filter unit. This can allow the air outlet to be connected either directly to the casing, or to an optional filter unit which is connected to the casing. | 09-29-2011 |
20110274558 | Modular windmill - The wind turbine is the best clean energy technology on land. The prior art of the wind powered turbine involves large towers and access to high winds and open land. Those blades require technological maintenance, sometimes of a high order. Large turbines serve well the purpose to provide whole communities of people with electric power. However, he wind turbine here provided needs no tower, high winds nor open acres. The appliance adapts to vertical or horizontal placement. It can be located on or near the ground on any surface stable enough to hold it. Its unique sail design takes advantage of small winds. The maintenance can be done by any competent mechanic. In the long run, the windmill turbine may pay for itself with electric economy and may begin to pay the owner from the grid. | 11-10-2011 |
20120014807 | DUSTPROOF AXIAL-FLOW FAN DEVICE - A dustproof axial-flow fan device includes an axial-flow fan and a mount body. The axial-flow fan has a frame body and a fan propeller rotatably mounted in the frame body. The mount body has an inlet and an outlet. At least one shutter slat is disposed at the inlet. A filter mesh is disposed at the outlet. An opening is formed at a bottom of the mount body. When the fan propeller forward rotates, air flows from the inlet into the mount body and filters through the filter mesh to flow out of the outlet. When the fan propeller reversely rotates, the shutter slat is closed to block the inlet. In this case, the air flows from the outlet into the mount body to blow off the dust from the filter mesh. The shutter slat will stop and make the dust drop out from the opening to remove the dust. | 01-19-2012 |
20130064679 | FAN GRILL FOR A MOSQUITO TRAP - A fan grill for a mosquito trap is a board and has a center, a funnel-shaped shell, multiple air holes and a through hole. The shell is formed downward in the center and is tapered off to a bottom. The air holes are respectively formed through the shell and are arranged radially and spirally. The through hole is formed on the bottom of the shell. The radial and spiral air holes are designed according to direction of airflow created by a fan so allow the airflow to pass smoothly therethrough and to generate steady suction forces. Besides, hole diameters of the air holes are less than sizes of mosquitoes so trapped mosquitoes are prevented from escaping from between fan blades of the fan. Therefore, trapping efficiency is enhanced. | 03-14-2013 |
20140154095 | FAN GUARD FOR AIR CONDITIONING MACHINE - A fan guard for a condenser unit of an air conditioner which supports the fan motor made of wire formed into a plurality of concentric rings or rectangles, or a spiral, secured to a spaced plurality of first radially-oriented elements each having at its peripherally-positioned end an orifice for fastening the guard to the unit and to an interspaced plurality of second radially-oriented elements each having at its end, closest to the fan guard's center, an orifice for fastening the motor to the guard, a third element extending all across the guard, and a sturdy ring affixed to at least the first and second elements proximate to the center. The guard preferably is convex whose wire elements have an elongated cross-sectional shape with lower airflow resistance. The fan guard has low fabrication and materials costs and allows use of motors with lower energy consumption for the same airflow efficiency. | 06-05-2014 |
20140334940 | PROTECTIVE COVER FOR FAN - Protective cover for a fan includes a center pole and two protecting members connected to opposite ends of the center pole. Each protecting member includes an outer frame, a plurality of connecting poles connected to the center pole and the outer frame, and a plurality of protecting bars connected to the connecting poles and arranged between the center pole and the outer frame. Each connecting pole defines a plurality of locking holes. The distance from the locking holes of each connecting pole to the center pole is different. | 11-13-2014 |
