Table saw having airflow apparatus

A table saw comprising:

• a table structure having a work surface;
• a motor assembly configured to rotate a saw blade, the motor assembly being adjustable relative to the work surface;
• a fan member coupled to the motor assembly and configured to generate an airflow during rotation of the saw blade;
• a blade case covering at least a portion of the saw blade, the blade case defining a blade case outlet and an access opening;
• and
• a guide structure extending through the access opening and having a guide input and a guide output, the guide input being positioned to receive the airflow, and the guide output being positioned within the blade case, wherein the guide structure further includes a channel extending between the guide input with a flange extending outwardly from the channel, wherein adjustment of the motor assembly in relation to the work surface causes adjustment of the guide structure in relation to the blade case, and further wherein the flange is positioned to cover the access opening during adjustment of the guide structure in relation to the blade case.

A cutting apparatus comprising:

• a table structure including a work surface;
• a blade case positioned under the work surface, the blade case including an airflow opening;
• an electrical motor assembly moveable relative to the blade case;
• a fan member connected to the electrical motor assembly;
• a duct member connected to the electrical motor assembly and positioned in the airflow opening, the duct member providing an airflow channel from the fan member to the blade case;
• and
• a cover member connected to the duct member, the cover member covering the airflow opening when the electrical motor assembly and the duct member are moved relative to the blade case,
• wherein the duct member includes an input port and an outlet port with a tube member extending between the input port and the outlet port, wherein the input port is positioned on an outer side of the first sidewall of the blade case and the outlet port is positioned on an inner side of the first sidewall of the blade case, and
• wherein the cover member extends radially outward from the tube member.

A power tool comprising:

• a table structure including a work surface;
• a motor assembly including an output drive positioned under the work surface, the motor assembly is adjustable relative to the work surface between a first position that is close to the work surface and a second position that is further from the work surface;
• a fan member coupled to the motor assembly and configured to generate an airflow;
• a blade case positioned under the work surface, the blade case including a first sidewall and an opposing second sidewall;
• and
• an air guide configured to channel the airflow into the blade case through an opening in the first sidewall, and the air guide further configured to move with the motor assembly between the first position and the second position, wherein the air guide covers the opening in both the first position and the second position,
• wherein the air guide includes a tube member positioned in the opening, the tube member having an input port and an outlet port, the input port being positioned on an outer side of the first sidewall of the blade case and the outlet port being positioned on an inner side of the first sidewall of the blade case, the tube member being movable with the motor assembly between the first position and the second position, and
• wherein the opening in the first sidewall is sized to permit the tube member to move with respect to the blade case such that the tube member extends through a first portion of the opening when the motor assembly is in the first position and extends through a second portion of the opening when the motor assembly is in the second position.
