DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following detailed description is of the best presently contemplated modes of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating general principles of embodiments of the invention. The scope of the invention is best defined by the appended claims.
FIGS. 1-3 illustrate one embodiment of a heater assembly 20 according to the present invention. The heater assembly 20 has a base portion 22, a blower portion 24 and a humidifier portion 26. The base portion 22 houses the circuit board, power system, and other electronics for the heater assembly 20. The circuit board, power system and electronics can be the same as for any of the conventional heater assemblies that are currently available in the marketplace, and will not be described in further detail. A power cord 28 extends from the base portion 22 to provide power from an external power source. A control panel 29 can be provided on a side wall 34 of the blower portion 24 for controlling the operation of the assembly 20.
The blower portion 24 has a heater 30 that is housed inside a housing that is made up of two side walls 32, 34 and a front wall 36 that are attached together to form a hollow interior space that receives and holds the heater 30. Air inlets 38 are provided in the side walls 32, 34 through which air can be drawn for use by the heater 30. Air outlets 40 are provided in the front wall 36 through which heated air can be ejected. In addition, water outlets 44 are provided in the front wall 36 through which water can be ejected.
Referring to FIGS. 2-3, the humidifier portion 26 can be any conventional humidifier that is provided at the top of the walls 32, 34, 36. The humidifier portion 26 includes the components of a conventional humidifier, including a housing 261 that houses a filter 262, a water tank 263, a motor (not shown) and a blower or fan 264. A mist section 265 is provided above the housing 261, and has mist outlets 266 through which cool or warm mist can be introduced into the environment. The motor can be retained in either the mist section 265 or the housing 261. A control panel 267 can be provided on either the mist section 265 or the housing 261 to allow for control of the humidifier separate from control for the heater 30. In addition, a power cord 268 extends from the housing 261 to allow power to be provided separately to the humidifier and the heater 30. Alternatively, wiring (not shown) can extend through the blower portion 24 to couple the circuit board and electronics in the base portion 22 to the motor in the humidifier portion 26.
A pump 42 is provided in the housing 261 of the humidifier portion 26. The pump 42 can be embodied in the form of any conventional negative-pressure pump, and functions to deliver water from the water tank 263 to at least one water tube 46 which extends from the humidifier portion 26 into the interior of the blower portion 24. Each water tube 46 is fluidly coupled to a corresponding water conduit 48 that is located at a position that is adjacent to the front wall 36. Water outlets 50 are provided on the conduit(s) 48 at locations adjacent to the water outlets 44.
In use, a user can turn on the heater 30 by controlling the control panel 29, such as by turning on one or more switches. The heater 30 emits warm air through the air and water outlets 40. In one embodiment, the blower portion 24 rotates in a reciprocal manner about the fixed base portion 22 to disperse the heat. If the user desires to provide a less dry (i.e., slightly more humid) environment, the user can turn on the humidifier by controlling the control panel 267 on the mist section 265. The user can additionally (and optionally) actuate the pump 42 (by pressing) to cause water to be pumped from the water tank 50 via the tube(s) 46 and conduit(s) 48, and ejected through the water outlets 50 and 44. Thus, the user can operate the heater 30 and the humidifier portion 26 separately and independently from each other. In other words, the user can operate the humidifier portion 26 alone, the heater 30 alone, or both the heater 30 and the humidifier portion 26.
Even though FIGS. 1-3 illustrate a heater assembly 20, the heater 30 can be a conventional cooling fan, in which case the blower portion 24 would be blowing cool air as opposed to warm air. The construction, structure and features of conventional blower portions used for fan assemblies are well-known to those skilled in the art.
In addition, although the humidifier portion 26 is illustrated as being provided above the blower portion 24, it is also possible to position the humidifier portion 26 below the blower portion 24, or to one side of either of the side walls 32 or 34.
FIGS. 4-6 illustrate one embodiment of a hair dryer assembly 100 according to the present invention. The hair dryer assembly 100 has a handle portion 102, a blower portion 104 and a water tank 106.
The handle portion 102 houses the electronics 108 for a conventional hair dryer. A power cord 110 extends from the handle portion 102 to supply external power to the hair dryer assembly 100. Switches 112 are provided on the handle portion 102 for controlling the hair dryer 100, including turning the hair dryer 100 on and off.
The blower portion 104 has a generally cylindrical housing 120 having an open rear end 122 and an open front end 124. A fan system 126, a heater 136 and a pump system are housed inside the housing 120. The fan system 126 is positioned adjacent the opening in the rear end 122, and includes a fan 130 carried on a shaft 132 extending from a motor 134 in a conventional manner well-known in the art. A heater 136 is positioned in front of the fan 130. The water tank 106 is positioned above the heater 136 through an opening 138 cut out of the housing 120. The water tank 106 has a water inlet 140 through which water can be introduced. A cover 128 blocks and secures the inlet 140. The pump system includes a sprayer 142 which is fluidly connected with the interior of the water tank 106 by a first tubing 144. The sprayer 142 is positioned between the heater 136 and the fan 130 adjacent the handle portion 102, and is coupled to a pump 146 that has a pump button 147 extending through the housing 120 for actuation and control by the user. The pump system further includes a spray mount 150 positioned adjacent the front end 124 and in front of the heater 136. A second tubing 148 extends below the heater 136 and fluidly connects the sprayer 142 and an internal conduit 152 provided in the spray mount 150. The internal conduit 152 is fluidly connected to a plurality of nozzles 154 through which water can be ejected. The pump 146 can be embodied in the form of any conventional negative-pressure pump, and functions to deliver water from the water tank 106 (via the tubings 144 and 148) to the spray mount 150.
The hair dryer assembly 100 can be used in the following manner. First, a switch 112 can be actuated to turn on the fan system 126 and the heater 136. The fan system 126 draws air through the opened rear end 122 and the fan 130 generates a flow of air that is directed towards the heater 136 and the front end 124 of the housing 120. The heater 136 generates heat to warm up the air that passes through the heater 136 from the fan 130 to the front end 124. The warmed air is blown out through the open front end 124. When the user desires to wet his or her hair, the user presses on the pump button 147, which creates negative pressure to draw water from the water tank 106 through the first tubing 144 to the sprayer 142 and pump 146, where the negative pressure further delivers the water through the second tubing 148 to the nozzles 154 (via the internal conduit 152 in the spray mount 150), where the water is ejected and sprayed. The water in the water tank 106 can be replenished by removing the cover 128 at the inlet 140 of the water tank 106.
FIGS. 7-10 illustrate one embodiment of a brush assembly 200 according to the present invention. The brush assembly 200 can be used as a conventional brush. The brush assembly 200 has a handle portion 202, a water tank 204, a water spray portion 206, and a brush portion BP1.
