Definitions
- the present invention relates to the field of power tools, and particularly, to a dust collection system for use with a portable planer.
- Portable planers are useful tools for any workshop. However, like many power tools, portable planers can generate significant amounts of dust and debris, such as wood chips or shavings, during use. Therefore, a number of systems have been developed for use with portable planers for collecting said dust and debris.
- Currently available dust collection systems may include a dust hood, which a user couples with the portable planer, for capturing dust and debris.
- the dust hood will typically include a vacuum attachment, such as for connecting a vacuum hose of a central vacuum system. These systems rely on suction force provided by the vacuum to draw dust and debris from the dust hood into a receptacle of the vacuum system.
- a drawback to this system is that the dust hood and vacuum system may not be included with the portable planer and thus, may have to be purchased as separate accessories and connected with the portable planer by the user. Further, such vacuum systems may take up a lot of space and may be relatively expensive.
- a number of portable planers include built-in dust collection systems.
- the built-in systems include a dust hood coupled to the planer for capturing dust and debris generated during use of the planer.
- the dust hood typically includes a blower, which is powered by the planer's motor, for directing dust/debris into an attached bag or receptacle.
- these systems no longer require a user to purchase separate components, such as a vacuum unit, to direct dust/debris from the dust hood, they are not without problems. For instance, because they implement a blower that is powered by the planer motor, these built-in systems may experience problems with power draw.
- planer motors include a thermal overload for detecting when the motor becomes overheated. Upon detection of overheating, the thermal overload will trip the circuit breaker, thereby causing the portable planer to shut down.
- the planer motor has to power both the portable planer and the blower of the dust hood, it may be vulnerable to overload. This may be especially true if, for example, the portable planer is set to a relatively large depth of cut. Therefore, a user may have to limit the planer's depth of cut in order to avoid overloading the planer motor and causing shut down. The end result is that the user is not getting optimal performance from his/her portable planer because the capabilities (ex.-the depth of cut) of the portable planer must be limited to avoid overloading the planer motor.
- the integrated dust collection system included a power source, independent from the planer motor, thereby improving performance over current systems by allowing a user to operate the portable planer without limiting its functionality.

Further, the motor is sized and dedicated for powering the blower assembly and is also capable of electrically coupling to a standard electrical supply.

Description
- The present application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 60/612,201 entitled: Dust Collection System filed Sep. 22, 2004, which is hereby incorporated by reference in its entirety.
- The present invention relates to the field of power tools, and particularly, to a dust collection system for use with a portable planer.
- Portable planers are useful tools for any workshop. However, like many power tools, portable planers can generate significant amounts of dust and debris, such as wood chips or shavings, during use. Therefore, a number of systems have been developed for use with portable planers for collecting said dust and debris. Currently available dust collection systems may include a dust hood, which a user couples with the portable planer, for capturing dust and debris. The dust hood will typically include a vacuum attachment, such as for connecting a vacuum hose of a central vacuum system. These systems rely on suction force provided by the vacuum to draw dust and debris from the dust hood into a receptacle of the vacuum system. A drawback to this system is that the dust hood and vacuum system may not be included with the portable planer and thus, may have to be purchased as separate accessories and connected with the portable planer by the user. Further, such vacuum systems may take up a lot of space and may be relatively expensive.
- In attempting to address the problems associated with the dust collection systems described above, a number of portable planers include built-in dust collection systems. The built-in systems include a dust hood coupled to the planer for capturing dust and debris generated during use of the planer. The dust hood typically includes a blower, which is powered by the planer's motor, for directing dust/debris into an attached bag or receptacle. Although these systems no longer require a user to purchase separate components, such as a vacuum unit, to direct dust/debris from the dust hood, they are not without problems. For instance, because they implement a blower that is powered by the planer motor, these built-in systems may experience problems with power draw. More specifically, many planer motors include a thermal overload for detecting when the motor becomes overheated. Upon detection of overheating, the thermal overload will trip the circuit breaker, thereby causing the portable planer to shut down. With the built-in dust collection systems, because the planer motor has to power both the portable planer and the blower of the dust hood, it may be vulnerable to overload. This may be especially true if, for example, the portable planer is set to a relatively large depth of cut. Therefore, a user may have to limit the planer's depth of cut in order to avoid overloading the planer motor and causing shut down. The end result is that the user is not getting optimal performance from his/her portable planer because the capabilities (ex.-the depth of cut) of the portable planer must be limited to avoid overloading the planer motor.
- Therefore, it would be advantageous to have a dust collection system integrated with a portable planer. It would be further advantageous if the integrated dust collection system included a power source, independent from the planer motor, thereby improving performance over current systems by allowing a user to operate the portable planer without limiting its functionality.
- Accordingly, a first aspect of the present invention is directed to an auxiliary dust collection system including a housing, a blower assembly, and a motor. The housing is configured for substantially directly coupling to a dust hood of a dust and debris-generating power tool. The blower assembly is contained within the housing. Further, the blower assembly is configured to both draw dust and debris generated by the power tool into the housing and to vent the dust and debris from the housing. The motor is contained within the housing and is operably coupled with the blower assembly. Further, the motor is sized and dedicated for powering the blower assembly and is also capable of electrically coupling to a standard electrical supply. The auxiliary dust collection system is configured for venting solely the dust and debris-generating power tool.
- An additional aspect of the present invention is directed to an auxiliary dust collection system including a dust hood, a housing, a blower assembly, and a motor. The dust hood is configured for substantially directly coupling to a dust and debris-generating power tool. The housing is configured for substantially directly coupling to the dust hood. The blower assembly is contained within the housing. Further, the blower assembly is configured for venting solely the dust and debris-generating power tool by both drawing dust and debris generated by the power tool into the housing and venting the dust and debris from the housing. The motor is contained within the housing and is operably coupled with the blower assembly. Further, the motor is sized and dedicated for powering the blower assembly and is also capable of electrically coupling to a standard electrical supply. Additionally, the blower assembly is coupled to a drive shaft of the motor.
- A further aspect of the present invention is directed to an auxiliary dust collection system for a portable planer, the system including a dust hood, a housing, a blower assembly, and a motor. The dust hood includes an inlet and an outlet formed therein. The inlet of the dust hood is configured for substantially directly coupling to the portable planer.
