     DETAILED DESCRIPTION 
     Hereinafter, the present disclosure will be described with reference to the accompanying drawings to explain a washstand cabinet including a blower or a drying module according to embodiments of the present disclosure. 
     As shown in  FIGS. 1 to 4 , a blower  1  according to one embodiment may include a blower main body  100  and a variable nozzle. The blower main body may move air from a main body suction port  120  formed in the lower end thereof to a main body discharge port  180  formed in the upper end thereof using an air-conditioning module (or dryer module)  160  provided therein. The variable nozzle  200 , may be connected to the upper end of the blower main body  100  (e.g., adjacent to the main body discharge port  180 ) so as to discharge the air from the blower main body  100  through a nozzle discharge port  210 , and the variable nozzle  200  may be configured to adjust the partial pressure of the air flow discharged through the nozzle discharge port  210  using a nozzle guide  230  provided therein. 
     The blower  1  according to the present embodiment may move air to the variable nozzle  200  through the blower main body  100 . The nozzle guide  230  provided inside the variable nozzle  200  may be moved to change position within the nozzle so that the outputted air may be discharged at different pressures at the left and right sides and/or the center of the nozzle discharge port  210 . 
     The blower main body  100  may suction air from the main body suction port  120  formed in the lower end thereof (e.g., opposite the nozzle  200 ) and may discharge the air through the main body discharge port  180  formed in the upper end thereof (e.g., adjacent to the nozzle  200 ). The blower main body  100  may include a case  110  having an elongated cylindrical shape to define the external shape of the blower main body  100 , and the air-conditioning module (or dryer module)  160  may be provided inside the case  110  to move the air inside the case  110 . The blower main body  100  may further include a rechargeable battery  140  that supplies power to the air-conditioning module  160 , and a charge terminal  130  that charges the rechargeable battery  140  from an external power source, such as a commercial power receptacle. 
     The case  110  may be provided with the main body suction port  120  in the peripheral direction of the lower end thereof. The case  110  may be provided with the main body discharge port  180  in the upper surface thereof to discharge air. The case  110  has an elongated cylindrical shape. The cylindrical case  110  may have a diameter that allows the user to grip the case  110  with his/her hand. 
     In the main body suction port  120 , a pre-filter  125  may be provided to primarily filter foreign substances in the air. The pre-filter  125  may have a perforated structure with holes or openings that are sized to primarily or initially filter foreign substances in the air that may be suctioned through the main body suction port  120 . An inner filter  150  may further be provided inside the case  110  to secondarily additional filter foreign substances in the air to be introduced into the air-conditioning module  160  (e.g., the air that has been initially filtered by the pre-filter  125 ). The inner filter  150  may have a perforated structure with holes or openings that are relatively smaller than the openings in the pre-filter  125 . 
     The air-conditioning module  160  may include a fan  163  that moves air via rotation thereof, and a motor  166  that drives the rotation of the fan  163 . The air-conditioning module  160  may be provided inside the case  110 , such as in the cavity formed within the cylindrical body. The air-conditioning module  160  may suction air through the main body suction port  120  formed at a distal end of the case  110  away from the nozzle  200 , such as the lower end of the case  110 . The air-conditioning module  160  may then discharge the air to the main body discharge port  180  formed in the upper end of the case  110  and adjacent to the nozzle  200 . 
     The rechargeable battery  140  may be provided inside the case  110 . The charge terminal  130  may be provided on the lower surface of the case  110 . The charge terminal  130  according to one embodiment may charge the rechargeable battery  140  when receiving power from the external power source. When the charge terminal  130  may be mounted to a washstand cabinet  10 , which will be described below, the charge terminal  130  may serve as a control terminal that controls the air-conditioning module  160  inside the blower main body  100  in response to a command input via an input unit of the washstand cabinet  10 . 
     The blower main body  100  may further include a control switch  170 , which selectively operates the motor  166  and the fan  163  inside the case  110 . The control switch  170  may be provided on the upper portion of the case  110 . The control switch  170  may control power of the blower  1 . In another example, the control switch  170  may change a position of the nozzle guide  230  inside the variable nozzle  200 , as will be described below. In addition, the control switch  170  may perform control to adjust the flow rate of air in the air-conditioning module  160 . 
     The variable nozzle  200  may discharge the air introduced from the blower main body  100  through the nozzle discharge port  210 . The nozzle discharge port  210  of the variable nozzle  200  may be shaped like an oblong slit that is relatively narrow in a first direction (e.g., along a minor axis) and is relatively long in a transverse, second direction (e.g., along a major axis). When the nozzle discharge port  210  has the slit shape, air may be injected in a wide range toward, for example, the bathroom floor or wall. In addition, when the nozzle discharge port  210  has the slit shape, water present on, for example, the bathroom floor or wall may be removed via, for example, forced convection by an air flow through the discharge port. 
     Referring to  FIG. 1 , in the description of the variable nozzle  200  according to the present embodiment, the direction in which the nozzle discharge port  210  and the nozzle suction port  220  may be aligned may be referred to as the front-and-rear direction, the direction in which the nozzle discharge port  210  gradually increases in width may be referred to as the left-and-right direction, and the direction orthogonal to both the front-and-rear direction and the left-and-right direction may be referred to as the vertical direction. The above-identified front-and-rear direction, the left-and-right direction and the vertical direction are given as examples to explain attributes of the variable nozzle of the present embodiment, and these directions are not intended to limit the scope of the present disclosure. For example, the nozzle discharge port  210  may have a differently shaped opening and/or the opening may be positioned in a different orientation. 
     In order to allow the variable nozzle  200  to discharge air within a wide range, the nozzle discharge port  210  may extend relatively longer in the left-and-right direction and may be relatively shorter in the vertical direction. 
     The nozzle suction port  220  of the variable nozzle  200  may have a shape corresponding to the blower main body  100 . For example, the nozzle suction port  220  may have a circular shape so as to correspond to opening of the cylindrical blower main body  100 . A flow path defined in the variable nozzle  200  may become narrower in the vertical direction and may become relatively wider in the left-and-right direction with increasing distance from the nozzle suction port  220  or decreasing distance to the nozzle discharge port  210 . 
     Inside the variable nozzle  200  according to the present embodiment, the nozzle guide  230  may be provided to adjust the partial pressure of the air discharged through the nozzle discharge port  210 . In one example, a pair of nozzle guides  230  may be provided symmetrically about a virtual left-and-right center axis  240  formed in the center of the longitudinal direction of the variable nozzle  200 . The two nozzle guides  230  may be configured so that the more that the two nozzle guides  230  are farther away from the from the nozzle suction port  220  and closer to the nozzle discharge port  210 , the farther the two nozzle guides  230  are positioned away from the left-and-right center axis  240 . 
     The nozzle guides  230  may be provided inside the variable nozzle  200 . The nozzle guides  230  may guide the air moving inside the variable nozzle  200 . The partial pressure of the air to be discharged may be changed depending on the orientation of the nozzle guides  230 . As the orientation of the nozzle guides  230  is changed, the air discharged through the nozzle discharge port  210  may exert high pressure in the left and right sides of the nozzle discharge port  210  as illustrated in section (a) of  FIG. 3 , may exert high pressure in the center of the nozzle discharge port  210  as illustrated in section (c) of  FIG. 3 , or may exert even pressure throughout the nozzle discharge port  210  as illustrated in section (b) of  FIG. 3 . 
     Each of the nozzle guides  230  may include a fixed guide  232 , which extends from the nozzle discharge port  210  and may be provided at a fixed position, and a movable guide  234 , which extends from the nozzle suction port  220  and may be movably provided, and a hinge point  236 , which causes change in the orientation of the movable guide  234 . The hinge point  236  may be the reference position about which the orientation of the movable guide  234  is changed. 
     In one example, the pair of nozzle guides  230  may include a pair of fixed guides  232 , a pair of hinge points  236 , and a pair of movable guides  234 . The pair of fixed guides  232  may extend from the hinge points  236  and toward the nozzle discharge port  210 . The pair of fixed guides  232  may be provided so as to be positioned farther away from the left-and-right center axis  240  with decreasing distance to the nozzle discharge port  210 . 
     When the pair of movable guides  234  extends from the hinge points  236  to the nozzle suction port  220 , the movable guides  234  may be changed in orientation about the respective hinge points  236  so as to rotate relative to the left-and-right center axis  240 . The adjacent ends of the pair of movable guides  234  that are close to the nozzle suction port  220  may be moved so as to gather to or be farther away from the left-and-right center axis  240 . 
     When the blower  1  according to the present embodiment is used to gather and push water, as illustrated in section (a) of  FIG. 3 , the ends of the pair of movable guides  234  may be provided so as to converge close to the left-and-right center axis  240 . Once the ends of the pair of movable guides  234  have converged close to the left-and-right center axis  240 , relatively high-pressure air may be discharged from the left and right sides of the nozzle discharge port  210 . 
     When the blower  1  according to the present embodiment is used to spread water, as illustrated in section (c) of  FIG. 3 , the ends of the pair of movable guides  234  may be provided so as to be farther away from the left-and-right center axis  240 . Once the ends of the pair of movable guides  234  have been moved to be located farther away from the left-and-right center axis  240 , relatively high-pressure air may be discharged from the center of the nozzle discharge port  210 . 
     In addition, when the blower  1  according to the present embodiment is used to push water like a broom, as illustrated in section (b) of  FIG. 3 , the ends of the movable guides  234  may be located between the positions of the ends of the movable guides  234  in section (a) of  FIG. 3  and the positions of the ends of the movable guides  234  in section (c) of  FIG. 3  so that even pressure is applied throughout the nozzle discharge port  210 . The positions of the ends of the movable guides  234  in section (b) of  FIG. 3  may be set through, for example, experimentations to optimize air flow, water movement, noise levels, etc. 
     The positions of the movable guides  234  illustrated in sections (a) to (c) of  FIG. 3  are provided merely as examples according to certain embodiment. In other examples, the movable guides  234  may be provided within the range between the examples shown in sections (a) and (b) of  FIG. 3  or within the range between the examples shown in sections (b) and (c) of  FIG. 3 .
