Apparatus, systems and methods of using 70 CFM ventilation fans with heaters for bathrooms having depressibly engageable and depressibly releaseable light covers. The novel ventilation fans and heaters can be mounted to structure in ceilings and inside walls with telescoping suspension brackets that are affixed directly to separate sides of the housing to support the housing against joists and structural supports behind the ceiling. Adjustable louvers on the grill cover allow for outgoing heated air to travel in a different direction into a space from the incoming air travelling into the housing. Plastic type housings around blower wheels reduce undesirable noise effects. Light covers can be easily opened and closed by using depressible engageable fasteners, and depressible release fasteners.

An electric heating device may heat an air flow through a duct of a ventilation, heating and/or air-conditioning installation of an automotive vehicle. The heating device may include at least one heating module that is contained in a heating body. The heating body may include a housing for controlling and supplying electrical power to the at least one heating module. The housing may include, in its interior, a printed circuit board from which a power supply connector and a control connector protrude. The housing may also include a power supply opening such that the power supply connector emerges from the housing and a control opening such that the control connector emerges from the housing. The housing may include a skirt that protrudes in parallel to the control connector on the periphery of the control opening. The skirt may be formed as a single part with the housing.

The invention is directed to a nozzle for a hot air device used in the electronic assembly industry to melt solder or heat shrink-wrap insulators. The nozzle provides a uniform temperature environment and suppresses the occurrence of local excess heating.

A system and apparatus for precision temperature control of thermal bead baths used in biological laboratories to heat biological samples is disclosed. The system has an insulated outer shell and an inner shell sealed together to form a recirculation pathway. The inner shell has an air extraction port opening into the recirculation pathway and at least one air injection port opening into the recirculation pathway. A fan is in the recirculation pathway and is positioned to draw air through the air extraction port. At least one thermal sensor is connected to a control and is disposed in close proximity to one of the air injection ports. Beads used in thermal bead baths are placed in a mesh basket inside the inner shell. The fan draws air from the inner shell through the beads and into the recirculation pathway, where the air is heated by a thermal element. The air flows past the thermal element and through the air injection ports back into the inner shell.

A heating system including at least one louver coupled with the housing of a heater including a blade and end caps on the blade for holding each louver in a fixed position during operation of the heater assembly, but also releasing the louver for adjustment in positioning relative to the axis of rotation of the louver to change air flow direction or other characteristics as desired.

A combination assembly or apparatus of a ceiling fan and heater. The combination assembly or apparatus includes a ceiling fan, a heater, a fan to blow air across the heater, a translucent band, motor driven rotating reflective foils each having mounted therein a light source (e.g. an LED) to shine through the translucent band to give a motion effect like a flickering.

A dryer includes a centrifugal impeller, a motor configured to rotate the impeller about a rotation axis which crosses a plane including a blowing axis, and a heater. The impeller is accommodated in a portion including a pair of side surfaces, each of which crosses the rotation axis, and an air inlet defined in at least one of the side surfaces. The impeller includes blades that are annular with the rotation axis as a center. The heater is supported on plate-shaped portions extending in a plurality of directions from the blowing axis in a cross-section perpendicular or substantially perpendicular to the blowing axis. A rear edge of each of the plate-shaped portions with respect to the blowing axis extends in a direction which crosses radially outer edges of the blades with respect to the rotation axis when viewed along the blowing axis.

A portable hand held hair dryer operable in a mode of operation to draw air through hair into the hair dryer. The hair dryer having at least one cyclone operable to separate water from the air flowing therethrough and an exterior separated water storage tank.

A heater assembly or dryer appliance, as provided herein, may include a housing, a heating element, and a thermostat. The housing may have an outer surface and an inner surface. The inner surface may define a chamber, an inlet, and an outlet. The housing may further include an embossing mount extending radially outward along the outer surface. The heating element may be disposed within the chamber to selectively heat air in a flow of heated air from the inlet to the outlet. The thermostat may be mounted on the outer surface of the housing. The thermostat may include a probe, a first mounting tab, and a second mounting tab. The probe may be positioned in thermal communication with the chamber. The first mounting tab may be secured to the embossing mount. The second mounting tab may be held against the outer surface.
