- the flow direction of the air blown by the blowing motor may be selectively manipulated to be internally directed toward a flow of suctioned liquid to prevent the suctioned liquid from flowing into the suction motor. Therefore, the redirected air flow can help prevent the suction motor unit 240 from being damaged due to introduction of the suctioned liquid.

- the present disclosure may additionally provide a remaining water suction device having an air blowing function which can eliminate a risk of damaging a suction motor in suctioning remaining water by jetting air to guide the suctioned liquid to a drain tank rather than to the suction motor and thus can be used safely for a long time.
- the present disclosure may include an air blowing module and a suction and blowing integrated nozzle. That is, in the present disclosure, air flow may be generated through the air blowing module, and the air flow may be sprayed to the wall surface through the suction and blowing integrated nozzle.

Abstract
Description
- This application claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2016-0134924, filed on Oct. 18, 2016, whose entire disclosure is hereby incorporated by reference.
- The present disclosure relates to a remaining water suction device having an air blowing function for sucking and removing water remaining on the surface of a window or a wall, and more specifically, the present disclosure relates to a remaining water suction device that functions to suction and remove remaining water and to blow strongly jetted air.
- In cleaning a surface of a window or a wall of a building, detergents and a large amount of washing water may be used. If some of the washing water remains on the surface of the window and is not wiped off, then dust (or the like) may adhere to the remaining washing water, and thus, re-contamination may occur easily.
- In addition, after cleaning a surface of a window or a wall, showering near the surface, or otherwise performing an activity that may cause water to be positioned on the surface, some water may remain on the surface. If the water remaining on the surface (hereinafter, referred to as “remaining water”) is not removed, bacteria and/or mold may reproduce on the surface to cause unsanitary conditions.
- Therefore, a remaining water suction device for removing the remaining water on a surface of a wall or a floor may be used.
FIG. 1 is a view of a conventional remaining water suction device, and other arrangements may also be provided. - As shown in
FIG. 1 , a conventional remainingwater suction device 10 may include asuction nozzle 12 having ansuction port 12 a, a water-air separation chamber 14 for separating water and air suctioned through thesuction nozzle 12, awater tank 15 for storing the water separated in the water-air separation chamber 14, asuction fan 17 for providing a suction force to the water-air separation chamber 14, and asuction motor 16 for driving thesuction fan 17. - Water may be suctioned through the
suction port 12 a using the suction force of thesuction fan 17, and the suctioned water may be stored in thewater tank 15. Further, the air, which may be suctioned together with the water through thesuction port 12 a, may be discharged through a discharge or exhaust port (not shown). - However, since the conventional remaining
water suction device 10 may suction portions of the remaining water by applying a suction force at thesuction port 12 a, as described above, the conventional remainingwater suction device 10 may be ineffective for removing other portions of the remaining water positioned away from thesuction port 12 a, such as remaining water on another surface. Furthermore, the conventional remainingwater suction device 10 may be ineffective at removing remaining water that is scattered to be distributed over a large surface area. - In addition, since the conventional remaining
water suction device 10 may only function to suction water, the conventional remainingwater suction device 10 cannot cause a portion of the remaining water near a drain hole of the bathroom or the toilet to be moved to and discharged through the drain hole. - Furthermore, if some liquid flows into the
suction motor 16 in the conventional remaining water suction device 10 (e.g., some of the suctioned water bypasses the water/air separation chamber 14), thesuction motor 16 may be damaged. A separate absorption filter may be provided in the air flow path to thesuction motor 16 to block water from reaching thesuction motor 16, but the positioning of the absorption filter at this location may result in a decrease in the efficiency of thesuction motor 16 and/or an increase in production costs. - Embodiments will be described in detail with reference to the following drawings in which like reference numerals refer to like elements and wherein:

FIG. 2 is a schematic block diagram illustrating a remainingwater suction device 20 having an air blowing function according to the present disclosure. The remainingwater suction device 20 may include both a remaining water suction function for suctioning remaining water and an air blowing function for moving the remaining water, and may selectively implement the remaining water suctioning function, the air blowing function, or a combination of the two functions. Other embodiments and configurations may also be provided. - The remaining water suction device (or water removal device) 20 may include a remaining
water suction module 21, anair blowing module 22, and acontroller 23. The user may select either the remaining water suctioning mode or the air blowing mode. The controller may selectively transmit a corresponding signal to the remainingwater suction module 21 or theair blowing module 22 to implement, respectively, the remaining water suctioning function or the air jetting (or blowing) function. Hereinafter, a detailed configuration, an organic coupling, and an operating relationship of the remaining water suctioning mode and the air blowing mode in the remainingwater suction device 20 according to the present disclosure will be described in more detail with reference toFIGS. 3 to 8 . -
FIG. 3 is a schematic view illustrating a configuration of a remainingwater suction device 100 having an air blowing function according to a first embodiment of the present disclosure. As shown inFIG. 3 , the remainingwater suction device 100 may includemain bodies drain tank 130, asuction motor unit 140, and an air blowing module 22 (seeFIG. 2 ). - The air blowing
module 22, which may serve to supply pressurized air to the suction and blowing integratednozzle 120, may include a blowingmotor 150 and a blowing duct portion (corresponding to a blowingduct 116 b described later) for moving air blown by the blowingmotor 150. The technical structure of theair blowing module 22 and the integration of theair blowing module 22 with the water suction function will be described later. - More specifically, the
main body 110 may include a firstmain body 110 a and a secondmain body 110 b. Asuction motor unit 140 and a blowingmotor 150 may be installed in the firstmain body 110 a, and thedrain tank 130 may be detachably coupled to the firstmain body 110 a. The secondmain body 110 b may be implemented as a fluid flow guide body for guiding suctioned remaining water and blown air. The firstmain body 110 a may be coupled to one end of the secondmain body 110 b, and the suction and blowing integratednozzle 120 may be mounted to the opposite end of the secondmain body 110 b. - As shown in detail in
FIGS. 3 and 4 , the secondmain body 110 b may include a suction portion (or suction chamber) 111 b, a partition portion (or partition plate) 112 b, an air discharge portion (or air discharge path) 113 b, a liquid discharge portion (or liquid discharge path) 114 b, anair flow chamber 115 b and a blowingduct 116 b. Thesuction portion 111 b may be formed in the shape of a through-hole, and remaining water and air may be simultaneously introduced thereinto from the suction and blowing integratednozzle 120. - The
partition portion 112 b may serve to move the remaining water introduced through thesuction portion 111 b to theliquid discharge portion 114 b. To this end, thepartition portion 112 b may be formed to face thesuction portion 111 b, and may be provided to be inclined downward toward theliquid discharge portion 114 b. Accordingly, the remaining water introduced through thesuction portion 111 b may first collides with thepartition portion 112 b, may then flow down thepartition portion 112 b, and may then flow to theliquid discharge portion 114 b. - The
liquid discharge portion 114 b may be formed to face thedrain tank 130 mounted on thefirst body 110 a. Meanwhile, the air introduced through thesuction portion 111 b may be guided by thepartition portion 112 b and may flow to theair discharge portion 113 b. Theair discharge portion 113 b may be formed to face thesuction motor unit 140, which may be mounted on the firstmain body 110 a. - The
air flow chamber 115 b may serve to cause the air flowing toward theliquid discharge portion 114 b to flow to theair discharge portion 113 b. Theair flow chamber 115 b may be positioned on the back of thepartition portion 112 b and may communicate with theair discharge portion 113 b. Here, thesuction portion 111 b may be positioned in front of thepartition portion 112 b. - The blowing
duct 116 b may be a component of a blowing duct portion in one embodiment of theair blowing module 23. The blowingduct 116 b may be formed to face the blowingmotor 150, which may be mounted in thefirst body 110 a. The blowingduct 116 b may have a cross-sectional area which gradually decreases from one end thereof facing the blowingmotor 150 to the opposite end such that the flow rate of the air blown by the blowingmotor 150 may be increased when the air blown by the blowingmotor 150 is jetted from the suction and blowing integratednozzle 120. The air pressurized by the shape of the blowingduct 116 b may be supplied to the suction and blowingintegrated nozzle 120. - The
main bodies main body 110 a and the secondmain body 110 b by the functions thereof. In one example, the firstmain body 110 a and the secondmain body 110 b may be integrally formed. - Next, as shown in detail in
FIG. 6 , the suction and blowingintegrated nozzle 120 may be provided with a suction portion (or suction head) 121 and a blowing portion (or blowing head) 122 to simultaneously perform suction of remaining water and jetting of air. Thesuction portion 121, which serves to suction remaining water, may be provided with a penetrated portion (or suction port) 121 a that may be penetrated from the outside of themain body 110 toward thesuction portion 111 b of the secondmain body 110 b. The penetratedportion 121 a may be formed as a substantially straight slit to improve suction efficiency by concentrating a suction air flow through the slit. - In addition, contact plate members (or contact blades) 121 b′ and 121 b″ may be mounted in or near the penetrated
portion 121 a. Thecontact plate members 121 b′ and 121 b″ may be provided to prevent damage to thesuction portion 121 or the wall surface (or the floor surface) upon contact with the wall surface (or the floor surface) and may be formed, for example, of a deformable elastic material. - The blowing
portion 122 may serve to discharge the pressurized air flowing from the blowingmotor 150 to the outside. To this end, the blowingportion 122 may include a penetrated portion (or blowing port) 122 a allowing the outside of themain body 110 to communicate (or provide an air flow path) with the blowingduct 116 b of the secondmain body 110 b. The penetratedportion 122 a may be formed to have a cross-sectional area that is gradually reduced in cross section area between an exterior opening and the blowingduct 116 b such that a nozzle is formed. For example, the cross-sectional area may be gradually reduced from the blowingduct 116 b to the penetratedportion 122 a such that the air blown by the blowingmotor 150 may be rapidly jetted through the blowingportion 122 of the suction and blowing integrated nozzle. - In addition, any liquid suctioned through the suction and blowing
integrated nozzle 120 may be stored in thedrain tank 130. As shown inFIG. 3 , thedrain tank 130 may be positioned in the secondmain body 110 a. - The
suction motor unit 140 may include asuction motor 141, asuction duct 142, and asuction fan 143. One end of thesuction duct 142 may be coupled to thesuction motor 141, and a second, opposite end thereof may be connected to theair discharge portion 113 b of the secondmain body 110 b. - Further, the blowing
motor 150 may be positioned to face the blowingduct 116 b of the secondmain body 110 b. For example, the blowingmotor 150 may be implemented as a fan motor or other component to generate an outward air flow through the blowingduct 116 b. Afilter 111 a may be mounted to the firstmain body 110 a, in which the blowingmotor 150 may be mounted. That is, thefilter 111 a may be mounted so as to face the blowingmotor 150. - The remaining
water suction device 100 having the air blowing function according to the first embodiment of the present disclosure may be constructed as described above with respect toFIGS. 3-6 . Hereinafter, the remaining water suction and air blowing in the first implementation will be described in more detail with reference toFIGS. 7 and 8 .FIG. 7 is a schematic view illustrating operation in a remaining water absorption mode of the remaining water suction device shown inFIG. 3 . - When the user selects the remaining water absorption mode to suck in water, the
suction motor 141 may be operated to drive thesuction fan 143 to generate a suction force. The suction force may cause remaining water and air to be introduced into thesuction portion 121 of the suction and blowingintegrated nozzle 120. Then, the liquid and the air introduced into thesuction portion 121 may flow into thesuction portion 111 b of the secondmain body 110 b. - First, flow of the liquid will be described. The liquid that has flowed into the
suction portion 111 b may collide with thepartition portion 112 b and then flow down thepartition portion 111 b. The liquid may be introduced into thedrain tank 130 through theliquid discharge portion 114 b. That is, the flow path of the liquid extends from thesuction portion 121 of the suction and blowingintegrated nozzle 120 to thesuction portion 111 b of the secondmain body 110 b, and then to thepartition portion 112 b to theliquid discharge portion 114 b to thedrain tank 130 as indicated by a leftward dotted line inFIG. 7 . - Next, the air flow will be described. The air that has flowed into the
suction portion 111 b may collide with or may be guided by thepartition portion 112 b and may be then introduced into thesuction duct 142 of thesuction motor unit 140 through theair discharge portion 113 b. Any air initially flowing toward theliquid discharge portion 114 b rather than toward theair discharge portion 113 b at thesuction portion 111 b may then flow toward theair discharge portion 113 b through theair flow chamber 115 b formed at the backside of thesuction portion 111 b and may be then introduced into thesuction duct 142. The air introduced into thesuction duct 142 may be discharged from the firstmain body 110 a via an outlet (now shown). In other words, as indicated by an alternated long and short dash line inFIG. 7 , the flow path of the air the flow path of the liquid extends from thesuction portion 121 of the suction and blowingintegrated nozzle 120 to thesuction portion 111 b of the secondmain body 110 b to thepartition portion 112 b to theair discharge portion 113 b to thesuction motor unit 140. -
FIG. 8 is a schematic view illustrating operation in an air blowing mode of the remainingwater suction device 100 shown inFIG. 3 . When the user selects the air blowing mode, the blowingmotor 150 may be operated. The air blown by the blowingmotor 150 flows to the blowingportion 122 of the suction and blowingintegrated nozzle 120 via the blowingduct 116 b of the secondmain body 110 b and may be then discharged to the outside via the penetratedportion 122 a. The blown air may be pressurized while passing through the blowingduct 116 b and the penetratedportion 122 a of the blowingportion 122, due to the gradually reduced cross-sectional area of the penetratedportion 122 a, such that the air can be jetted from the penetratedportion 122 a in a pressurized state. That is, as indicated by a dotted line inFIG. 8 , the flow path of the air blown by the blowingmotor 150 extends from the blowingduct 116 b to the penetratedportion 122 a of the blowing portion. - As described above, according to the first embodiment of the present disclosure, in the remaining
water suction device 100 having the air blowing function, the remaining water suction mode and the air blowing mode can be selectively activated according to an input or other control operation by the user. -
FIG. 9 is a schematic view illustrating a configuration of a remainingwater suction device 200 having an air blowing function according to a second embodiment of the present disclosure, andFIG. 10 is a schematic cross-sectional view of a fluid flow guide body in the remaining water suction device shown inFIG. 9 . As shown inFIGS. 9 and 10 , a difference between the remainingwater suction device 200 according to the second embodiment and the remainingwater suction device 100 according to the first embodiment shown inFIG. 2 includes a configuration of the secondmain body 210 a and theblower motor 250. - More specifically, the remaining
water suction device 200 may include first and secondmain bodies integrated nozzle 220, adrain tank 230, asuction motor unit 240, and a blowingmotor 250. As described above, the firstmain body 210 a, the suction and blowingintegrated nozzle 220, thedrain tank 230, and thesuction motor unit 240 may be similar to the corresponding elements of the remainingwater suction device 100 in the first embodiment depicted inFIG. 3 , and thus a detailed description thereof will be omitted. - In addition to blowing air out of the suction and blowing
integrated nozzle 220, the remainingwater suction device 200 according to the second embodiment of the present disclosure may selectively jet air blown by theair blowing motor 250 toward theliquid discharge portion 214 b. This functionality may help to prevent the liquid suctioned through the suction and blowingintegrated nozzle 220 from flowing into thesuction motor unit 240 and to further improve suction efficiency. - To this end, the second
main body 210 b, which may be a fluid guide body that may function to guide air and liquids sucked in through the suction and blowingintegrated nozzle 220, may include asuction portion 211 b, apartition portion 212 b, anair discharge portion 213 b, aliquid discharge portion 214 b, anair flow chamber 215 b, and a blowingduct 216 b. - The blowing
duct 216 b may be arranged to face the blowingmotor 250 mounted on the firstmain body 210 a. In the second embodiment depicted inFIG. 9 , the blowingduct 216 b may be provided with a throughhole 216 b′ facing the front part (or surface) of thepartition portion 212 b, that is, an area between thesuction portion 211 b and thepartition portion 212 b. - As described below, the through
hole 216 b′ may be provided to selectively jet the air blown by the blowingmotor 250 toward theliquid discharge portion 214 b. For example, in order to selectively open and close the throughhole 216 b′, an opening/closingcontrol lever unit 217 b may be mounted on the secondmain body 210 b. For example, when suctioning the remaining water through the suction and blowingintegrated nozzle 220, air should not be jetted through the suction and blowing integrated nozzle. Therefore, the air blown by the blowingmotor 250 may not flow to the blowingportion 222 of the suction and blowingintegrated nozzle 220 but may flow toward theliquid discharge portion 114 b through the throughhole 216 b′ when thesuction motor unit 240 is activated. - To implement this configuration, the opening/closing control lever unit may be adopted in various ways.
FIGS. 10 and 11 illustrate an example of an opening/closingcontrol lever unit 217 b that may include alever 217 b′ and a blockingplate 217 b″ as an embodiment. More specifically, thelever 217 b′ may be exposed to the outside of the secondmain body 210 b (e.g., through an opening in the secondmain body 210 b) and may be coupled to one side or both sides of the blockingplate 217 b″. The blockingplate 217 b″ may be moved by operation of thelever 217 b′. - The blocking
plate 217 b″ may be located inside the blowingduct 216 b and may be provided to cover the throughhole 216 b′. The blockingplate 217 b″ may be mounted on the second main body so as to be rotatable or otherwise moveable from the throughhole 216 b′ by operation of thelever 217 b′. The blockingplate 217 b″ may be formed as a plate from of an elastic material (or other material) to selectively open and close the throughhole 216 b′ while moving inside the blowingduct 216 b. For example, the blockingplate 217 b″ may be hingedly connected within the blowingduct 216 b such that the blockingplate 217 b″ can be flipped, rotated, or otherwise moved between a first position that blocks the throughhole 216 b′ but does not impede the blowingduct 216 b to a second position that exposes the throughhole 216 b′ and blocks the blowingduct 216 b. In another example, the blockingplate 217 b″ correspond to a baffle that directs air flow from the blowingmotor 250 to one of the blowingduct 216 b or the through hole 216″. In yet another example, the blockingplate 217 b″ may direct a first portion of the air flow from the blowingmotor 250 to the blowingduct 216 b and a second portion of the air flow from the blowingmotor 250 to or the through hole 216″. - The
air blowing motor 250 may have an adjustable air flow speed. For example, theair blowing motor 250 may provide air at a relatively high air flow speed (or ranges of air flow speeds) in the air blowing mode (e.g., when the blockingplate 217 b″ blocks the throughhole 216 b′) such that high velocity (or high pressure) air is directed through the blowingportion 222 of the suction and blowing integrated nozzle 220). However, when air from theair blowing motor 250 is directed through the throughhole 216 b′ (e.g., when the blockingplate 217 b″ is moved to expose the throughhole 216 b′), the air may be provided by theair blowing motor 250 at a lower air flow speed (or lower air pressure) than in the air blowing mode. The air flow speed in the blowingmotor 250 may be adjusting using a conventional technology that may be easily implemented by those skilled in the art, and thus a detailed description thereof will be omitted. For example, the air flow speed from the blowingmotor 250 may be adjusted by modifying a current and/or voltage driving the blowingmotor 250 and/or by selectively positioning one or more other components (e.g., a blocking surface) one or more of an inlet or an outlet of the blowingmotor 250. - The remaining
water suction device 200 according to the second embodiment of the present disclosure may be configured as described above to provide the air blowing function. Hereinafter, the respective technical implementation processes of the remaining water suction and air blowing will be described in more detail with reference toFIGS. 11 and 12 . -
FIG. 12 is a schematic view illustrating an operation in a remaining water absorption mode of the remainingwater suction device 200 shown inFIG. 9 . For example, when a liquid (e.g., remaining water) is to be suctioned through the suction and blowingintegrated nozzle 220, the user may use or otherwise activate thelever 217 b′ to move the blockingplate 217 b″ to open the throughhole 216 b′ and close the side of the blowingduct 216 b connected to the penetratedportion 222 a of the suction and blowingintegrated nozzle 220. For example, the blockingplate 217 b″ may be rotatably mounted within the blowingduct 216 b such that the blockingplate 217 b″ may by moved by thelever 217 b′ between a first position blocking the throughhole 216 b′ while exposing the blowingduct 216 b and a second position exposing the throughhole 216 b′ while blocking the blowingduct 216 b. - When the remaining water absorption mode is selected, the
suction motor 241 may be operated to drive thesuction fan 243, and the remaining water and air may be introduced into (i.e., sucked through) the suction portion 221 of the suction and blowingintegrated nozzle 220 by a suction force generated by thesuction fan 243. The liquid and the air introduced through the suction portion 221 may flow to thesuction portion 211 b of the secondmain body 210 b. - When the blowing
motor 250 is operated and the liquid flowing into thesuction portion 211 b collides with thepartition portion 212 b, the air blown by the blowingmotor 250 may be jetted toward theliquid discharge portion 214 b through the throughhole 216 b′. As a result of the air flow though the throughhole 216 b′, the liquid present in thesuction portion 211 b may be guided to theliquid discharge portion 214 b at thepartition portion 212 b and may, thus, be prevented from flowing to thesuction motor unit 240. That is, air flow through the throughhole 216 b′ may forcibly guide the flow of the liquid toward theliquid discharging portion 214 b and away from theair discharge portion 213 b. As previously described, the liquid in theliquid discharging portion 214 b may be introduced into thedrain tank 230, and the air flow in theair discharge portion 213 b may be introduced into thesuction duct 242 of thesuction motor unit 240 through theair flow chamber 215 b and may be discharged to an outside of the remainingwater suction device 200. -
FIG. 13 is a schematic view illustrating operation in an air blowing mode of the remaining water suction device shown inFIG. 9 . In the an air blowing mode, the user may use thelever 217 b′ to move the blockingplate 217 b″ to close the throughhole 216 b′ and open the side of the blowingduct 116 b connected to the penetratedportion 222 a of the suction and blowingintegrated nozzle 220. In another example, thelever 217 b′ may be automatically moved (e.g., without an input from the user) when the blowingmotor 250 is activated while thesuction motor unit 240 is inactivate. For example, thelever 217 b may be selectively driven by an actuating motor (not shown) based on the status of at least one of thesuction motor unit 240 or the blowingmotor 250. - When the air blowing mode is selected, the air blown by the blowing
motor 250 may flow into the blowingduct 216 b of the secondmain body 210 b, and may be jetted outward through the blowingportion 222 of the suction and blowingintegrated nozzle 220. In the air blowing mode, the throughhole 216 b′ may be closed and the blowingduct 216 b is not impeded by the blockingplate 217 b″ such air from the blowingmotor 250 can be jetted outward through the suction and blowingintegrated nozzle 220 without loss. - Consequently, in the remaining
water suction device 200 having the air blowing function according to the second embodiment configured as above, when the remaining water is suctioned, the flow direction of the air blown by the blowing motor may be selectively manipulated to be internally directed toward a flow of suctioned liquid to prevent the suctioned liquid from flowing into the suction motor. Therefore, the redirected air flow can help prevent thesuction motor unit 240 from being damaged due to introduction of the suctioned liquid. - The present disclosure may provide a remaining water suction device having an air blowing function which is capable of effectively removing water from a wall surface by separating remaining water stuck to the wall surface from the wall surface by blowing air to the remaining water. The present disclosure may also provide a remaining water suction device having an air blowing function which is capable of effectively removing remaining water sporadically distributed on the floor by collecting the remaining water at one place and suctioning the collected remaining water at one time.
- The present disclosure may further provide a remaining water suction device having an air blowing function which is capable of effectively removing remaining water by jetting air onto the remaining water near a drain hole and discharging the remaining water through the drain hole. The present disclosure may additionally provide a remaining water suction device having an air blowing function which can eliminate a risk of damaging a suction motor in suctioning remaining water by jetting air to guide the suctioned liquid to a drain tank rather than to the suction motor and thus can be used safely for a long time.
- The present disclosure may include an air blowing module and a suction and blowing integrated nozzle. That is, in the present disclosure, air flow may be generated through the air blowing module, and the air flow may be sprayed to the wall surface through the suction and blowing integrated nozzle. Thereby, the remaining water may be effectively removed from the wall surface. Accordingly, bacteria and fungi may be prevented from growing due to the remaining water to create an unsanitary condition or corrode the wall surface.
- As described above, the conventional remaining water suction device cannot effectively remove remaining water which may be not gathered at one place but may be scattered sporadically on the floor surface. To address this concern, a remaining water suction device according to the present disclosure may include a suction and blowing integrated nozzle, a suction motor unit, a drain tank, and an air blowing module. Specifically, in the remaining water suction device according to the present disclosure, air flow may be generated through the air blowing module and jetted onto the sporadically scattered remaining water through the suction and blowing integrated nozzle, thereby collecting the remaining water at one place. Further, the collected remaining water may be suctioned at once and stored in the drain tank using the suction motor and the suction and blowing integrated nozzle. Thus, the scattered remaining water may be effectively removed, thereby addressing the problem of incomplete suctioning of the remaining water.
- In addition, as described above, in the case of the conventional remaining water suction device, even the remaining water near the drain hole of the bathroom or toilet must be suctioned and removed. To address this issue, the remaining water suction device according to the present disclosure may include an air blowing module and a suction and blowing integrated nozzle. More specifically, in the present disclosure, air flow may be generated through the air blowing module and jetted onto the remaining water near the drain hole through the suction and blowing integrated nozzle such that the remaining water may be moved to and discharged through the drain hole. Thus, the remaining water suction device according to the present disclosure may neatly remove the remaining water near the drain hole without separate suctioning of the remaining water.
- Further, as described above, according to the conventional remaining water suction device, when the suctioned liquid may be introduced into the suction motor, there may be a risk of damaging the suction motor. To address this issue, the remaining water suction device according to the present disclosure may include an opening/closing control lever unit for selectively directing the air flow generated from the blowing motor toward the suction and blowing integrated nozzle or the main body.
- That is, in the present disclosure, when the remaining water is suctioned, the air blowing duct directed to the suction and blowing integrated nozzle may be blocked, and the air flow generated from the blowing motor may be jetted toward the drain tank through a through hole. Therefore, the internal air flow may direct the suctioned liquid away from the suction motor and may prevented the suctioned liquid from flowing into the suction motor such that a service life of the product may be enhanced.
- According to the present disclosure, the user can select a remaining water suction mode or an air blowing mode according to, for example, the type and state of remaining water. Thus, remaining water may be more effectively removed. In other words, remaining water stuck to the surface of a wall, which can be removed by suctioning, may be removed from the surface of the wall by selecting the air blowing mode according to the condition of the wall surface or the degree of distribution of the remaining water and jetting air onto the remaining water. Conversely, if the remaining water scattered sporadically in a large area of a wall surface or out of a reach of the user (e.g., on a ceiling surface), it takes a long time to remove the remaining water using a suctioning function, whereas an outward air flow function may allow the distributed remaining water to be removed in a relatively short time.
- In addition, the present disclosure may eliminate the need for laborious suctioning of remaining water scattered sporadically around the bathroom floor and shorten the time needed to remove the remaining water by jetting air onto the remaining water to collect the remaining water at one place and suction the collected remaining water at once. Further, as the air is blown, a bathroom floor or other surface may be quickly dried. Further, according to the present disclosure, by jetting air to discharge the remaining water near the drain hole through the drain hole without suctioning the remaining water, the remaining water may be effectively removed through the drain hole, and the work time for removing the remaining water may also be shortened.
- According to the present disclosure, when the remaining water is suctioned, an air flow may be used to prevent the suctioned liquid from flowing into the suction motor by selectively adjusting the flow direction of the air flow generated from the air blowing motor. Therefore, the suction motor may be protected from damages caused by an introduced liquid. Further, the adjustable air flow may avoid a need for installation of a separate filter for blocking introduction of the liquid into the suction motor. Therefore, manufacturing costs may be reduced.
- It is to be understood that the above-described embodiments may be to be considered in all respects as illustrative and not restrictive, and the scope of the disclosure should be defined by the appended claims rather than by the foregoing description. It is intended that all changes and modifications that come within the meaning and range of equivalency of the claims, as well as any equivalents thereof, be within the scope of the present disclosure.
