[0045] Unless otherwise stated, singular expressions described in this disclosure may include a plural meaning, and this applies likewise to singular expressions described in the claims.

[0046] Hereinafter, a preferred embodiment of the smart foot washing device according to the present invention will be described in detail with reference to the attached drawings.

[0047]

[0048] The present invention relates to a smart foot washing device (50) that is easy to store by reducing its volume when not in use, and can automatically wash feet by unfolding it when in use.

[0049] First, the configuration of the smart foot washing device (50) according to the first embodiment of the present invention may include, as shown in FIGS. 1 to 5, a main body (100) equipped with a water supply pipe (110) connected to a water supply device such as a washbasin or shower and a cleaning agent cartridge (120) in which a cleaning agent is stored; and a foot washing unit (200) installed to be extendable toward the ground from the main body (100).

[0050] To explain in more detail, the main body (100) can be installed near a water supply device such as a washbasin or shower, and it goes without saying that it can be installed in various locations without restriction when using a separate water bottle or water tank for water supply.

[0051] Therefore, the above water supply pipe (110) can be connected to branch off from a water pipe such as a washbasin or shower, or a water bottle can be directly connected and installed, or a water tank can be connected and used with a hose.

[0052] Of course, it is most desirable to connect it to water pipes such as those for a washbasin or shower to supply both hot and cold water.

[0053] In addition, the main body (100) may be provided with a power supply unit (130) for supplying power to the control configuration and driving devices to be described later. The power supply unit (130) may receive power by connecting directly to a power supply means, or it may be composed of a rechargeable power source such as a battery.

[0054] Meanwhile, the cleaning agent cartridge (120) can be detachably installed inside the main body (100).

[0055] Therefore, when all the cleaning agent stored in the cleaning agent cartridge (120) is used, the cleaning agent cartridge (120) can be refilled or replaced for use.

[0056] In addition, the cleaning agent cartridge (120) can store various types of cleaning agents such as cleaning power, deodorizing power, and fragrance, so that the user can easily replace and install the cleaning agent cartridge (120) that stores the cleaning agent preferred by the user, thereby increasing the user's satisfaction.

[0057] Here, the cleaning agent cartridge (120) may store not only a cleaning agent but also a chemical solution.

[0058] Meanwhile, the main body (100) may have a space (102) formed therein in which the foot washing part (200) can be stored when folded.

[0059] The above space (102) is formed with a sufficient size so that the above foot washing unit (200) can be fully accommodated in the above space (102) in a folded state.

[0060] Therefore, when storing the foot washing unit (200), the foot washing unit (200) is not protruded to the outside of the main body (100), thereby improving waterproofing and aesthetics, and the volume occupied by the smart foot washing device (50) of the present invention in the installation space is minimized, thereby increasing the utilization of the installation space.

[0061]

[0062] Meanwhile, the foot washing unit (200) may include a pad body (210), a washing water spray nozzle (220) and a cleaning agent spray nozzle (230) that spray washing water and cleaning agent supplied from a washing water transfer pipe (310) and a cleaning agent transfer pipe (320) to the pad body (210), and a brush (240) installed on the pad body (210) and corresponding to each part of the foot.

[0063] At this time, the pad body (210) is connected to the space (102) of the main body part (100) so as to be rotatable by means of a hinge at the bottom and is installed so as to be deployed toward the ground.

[0064] The above pad body (210) may be unfolded by the user manually operating it, or it may be unfolded by driving a motor connected to the hinge through the control unit (140).

[0065] In addition, the pad body (210; 210a, 210b) may be configured to be folded in two stages.

[0066] Therefore, the length of the pad body (210) can be further shortened when folded, and as a result, the height of the space (102) required to accommodate the foot washing part (200) is lowered, so the height of the main body part (100) can be minimized.

[0067] In addition, the pad body (210) can be set so that the angle with the ground when unfolded is 0° to 45° depending on the position of the end fixed to the main body part (100) or the installation of a separately provided support stand (not shown). Due to the above configuration, it has the effect of being able to be used comfortably in various postures, such as standing directly on the pad body (210) or sitting on a chair.

[0068] In addition, the pad body (210) has a plurality of drainage grooves (not shown) formed therein so that the sprayed cleaning water and cleaning agent can be smoothly discharged downward along with the contaminants.

[0069] In addition, a protective pad (not shown) that prevents slipping and prevents damage to the pad body (210) may be further provided at a position supported on the ground of the pad body (210).

[0070] In addition, the washing water spray nozzle (220) and the cleaning agent spray nozzle (230) may be provided not only on the pad body (210) but also on the frame (244a, 246a) where the brush (240) is installed, so that the washing water and cleaning agent can be evenly sprayed on each part of the foot.

[0071] In addition, a vibrator (350) may be further provided in the cleaning agent transfer pipe (320) adjacent to the cleaning agent spray nozzle (230).

[0072] The cleaning agent supplied in foam form through the cleaning agent transfer pipe (320) can be vibrated once more by the vibrator (350) just before spraying to make the cleaning agent foam denser and softer.

[0073] In addition, the brush (240) is installed at a position corresponding to each part of the foot so that it can rub each part of the three-dimensional foot.

[0074] That is, the brush (240) may include a first brush (242) corresponding to the sole of the foot, a second brush (244) corresponding to the instep and toes, and a third brush (246) corresponding to the heel.

[0075] At this time, the brushes (240) may be installed in a fixed manner, or may be installed to be driven electrically by installing a driving means such as a motor.

[0076] More specifically, the first brush (242) is installed at a position where the sole of the foot is supported on the upper surface of the pad body (210a) in the unfolded state of the pad body (210), and can be configured to be fixed, rotate in place, or vibrate.

[0077] Additionally, the second brush (244) may be provided to be able to stand up or be withdrawn upward from the pad body (210a) in the unfolded state of the pad body (210).

[0078] That is, the second brush (244) is rotatably installed on the frame (244a), and the frame (244a) is formed in a "U" shape, with both bent ends installed on the pad body (210), and the front part of the foot is positioned in the space between the pad body (210a) and the second brush (244).

[0079] At this time, the frame (244a) is manually raised or lowered by the user, or raised or lowered relative to the pad body (210a) by a driving means such as a motor built into the pad body (210a), so that the second brush (244) comes into contact with the user's instep and toes, etc.

[0080] Afterwards, as the user moves back and forth with respect to the second brush (244), the second brush (244) can wash the upper part of the foot, such as the instep and toes.

[0081] In particular, the second brush (244) may be further equipped with a relatively long bristles (245) in the middle, and the bristles (245) serve to enter between the toes and clean.

[0082] In addition, the frame (244a) can be installed to be movable in the longitudinal direction of the pad body (210).

[0083] Therefore, when the frame (244a) moves in the longitudinal direction of the pad body (210) while standing or pulled out, the second brush (244) rubs the upper part of the foot, such as the instep and toes, so that the foot can be washed more comfortably.

[0084] At this time, the height of the frame (244a) is continuously adjusted to correspond to the height from the top of the user's foot to the toes, so that the second brush (244) can be maintained in contact with the upper part of the foot.

[0085] In particular, the end of the frame (244a) coupled to the pad body (210a) may be supported by an elastic member (not shown).

[0086] Therefore, when the foot is positioned in the space between the pad body (210a) and the second brush (244), as the elastic member (not shown) of the frame (244a) is extended, the height of the frame (244a) is finely adjusted to match the height of the instep, thereby allowing the second brush (244) to effectively maintain contact with the user's instep.

[0087] Additionally, the third brush (246) may be provided to be able to stand up or be withdrawn upward relative to the pad body (210b).

[0088] That is, the third brush (246) is rotatably installed on the frame (246a), and the frame (246a) is formed in a straight or "U" shape, with both bent ends installed on the pad body (210b).

[0089] At this time, the user manually raises or lowers the frame (246a), or raises or lowers it relative to the pad body (210) by a driving means such as a motor built into the pad body (210b), so that the third brush (246) comes into contact with the heel.

[0090] Afterwards, the frame (246a) is repeatedly driven to stand up or extend by the driving means, allowing the third brush (246) to wash the heel.

[0091] In addition, as illustrated in FIG. 6, according to the second embodiment of the present invention, a fourth brush (248) corresponding to the toe may be further provided so as to clean the toe more effectively.

[0092] The above-mentioned fourth brush (248) is installed on a frame (248a) installed on the main body (100), and the frame (248a) is formed in a straight shape or a "U" shape and is configured to be able to stand up or be withdrawn from the main body (100).

[0093] Of course, the configuration for standing up or pulling out the above frame (248a) from the main body (100) can be performed manually or electrically, as with the other brushes described above.

[0094] In particular, the fourth brush (248) may be further provided with a relatively long bristles (not shown) in the middle, similar to the second brush (244), so that the bristles (not shown) of the fourth brush (248) can enter between the toes to clean, or may be formed concavely in a shape corresponding to the outer shape of the toes so that not only the upper part of the toes but also the side part between them can be effectively cleaned.

[0095] Here, the first brush (242), second brush (244), brush head (245), third brush (246), and fourth brush (248) may be formed with a brush head equipped with a bristles or a sponge, and in particular, the third brush (246) may be made of a rough material such as having micro-protrusions or micro-grooves formed therein to remove dead skin cells from the heel.

[0096] In addition, it is desirable to ensure that the second brush (244) and the third brush (246) are completely stored in the pad body (210) when not in use, and that the fourth brush (248) is completely stored in the main body part (100), so that the volume can be reduced when folded.

[0097] Meanwhile, it is preferable that the brushes (240) are detachably installed on the pad body (210) or the frame (244a, 246a, 248a) so that they can be replaced in case of contamination or damage, thereby allowing for more hygienic maintenance.

[0098] In addition, the control unit (140) can further clean the brush (240) by spraying additional cleaning water when the cleaning of the foot is finished, thereby allowing the brush (240) to be cleaned more cleanly.

[0099] Meanwhile, the smart foot washing device (50) according to the present invention may be in a form in which at least one of the first brush (242), the second brush (244), the third brush (246), and the fourth brush (248) is installed, and it is obvious that it can be formed in various combinations.

[0100] Additionally, the first brush (242), second brush (244), third brush (246), and fourth brush (248) may be fixed to the pad body (210) or frame (244a, 246a, 248a) so that the user can clean by moving their foot forward, backward, or sideways, or the brush head may be electric so that the brush head rotates by a motor, etc. so that cleaning is performed by electric power.

[0101]

[0102] Meanwhile, as illustrated in FIGS. 7 to 9, the smart foot washing device (50') according to the third embodiment of the present invention may have a main body (1000) in which the foot washing unit (2000) is accommodated, and a water tank (1020) in which washing water and a cleaning agent to be described later are stored in the lower part in which the foot washing unit (2000) is accommodated.

[0103] The above main body (1000) is formed with a sufficient size to be fully accommodated in the basic state where the length of the above foot washing part (2000) is shortened.

[0104] Therefore, when storing the foot washing unit (2000), the foot washing unit (2000) is not protruded to the outside of the main body (1000), thereby improving waterproofing and aesthetics, and the volume occupied by the smart foot washing device (50) of the present invention in the installation space is minimized, thereby increasing the utilization of the installation space.

[0105] In addition, the inner bottom surface of the above-mentioned reservoir (1020) is formed to be inclined toward the drain hole (1040), and a drain pipe is connected to the drain hole (1040) so that the washing water and cleaning agent can be drained through the drain pipe, thereby preventing leakage to the surroundings.

[0106] In addition, the main body (1000) may be provided with legs (10) at the bottom, and the legs (10) are structured to be height-adjustable, thereby having the effect of adjusting the height of the smart foot washing device (50').

[0107]

[0108] Meanwhile, the above foot washing unit (2000) may form a receiving unit (2020) in which a foot is received by including a first body (2100) and a second body (2200) installed to be extendable forward in the longitudinal direction of the first body (2100).

[0109] Additionally, the first body (2100) and the second body (2200) are equipped with a washing water spray nozzle (2410) and a cleaning agent spray nozzle (2420) that spray washing water or cleaning agent supplied from the washing water transfer pipe (310) and the cleaning agent transfer pipe (320) into the space, and may be equipped with a brush (2500) corresponding to each part of the foot.

[0110] In addition, the first body (2100) and the second body (2200) are formed with a plurality of drainage holes (not shown) so that the washing water and cleaning agent sprayed from the washing water spray nozzle (2410) and the cleaning agent spray nozzle (2420) can be smoothly discharged downward along with contaminants.

[0111] Therefore, with the feet placed in the receiving portion (2020) of the first body (2100) and the second body (2200), washing water and a cleaning agent can be sprayed from the washing water spray nozzle (2410) and the cleaning agent spray nozzle (2420), and the feet can be cleaned using a brush (2500).

[0112] To explain in more detail, when a foot is received in the receiving portion (2020), the heel of the foot rests on the first body (2100), and the forefoot rests on the second body (2200).

[0113] At this time, as the second body (2200) is pulled out in front of the first body (2100) relative to the first body (2100), the length of the foot washing unit (2000) is adjusted, and can be adjusted to an appropriate length according to the user's foot size.

[0114] The configuration for adjusting the length between the first body (2100) and the second body (2200) can be made in various ways using known structures such as mechanical, electric, or hydraulic structures, and can be adjusted by a user manually operating it, or can be adjusted by driving a motor, etc. through the control unit (140).

[0115] Additionally, the main body (100) may further be provided with a pivot member (170) having one end rotatably installed on the main body (100) and the other end rotatably installed on the second body (2200).

[0116] At this time, the rotating member (170) is formed with an adjustable antenna structure, etc., and when the second body (2200) is pulled out to the front of the first body (2100), its length increases and it serves to support the load of the second body (2200).

[0117] In addition, the rotating member (170) has the effect of guiding the washing water and cleaning agent drained through the drain hole (not shown in the drawing) of the second body (2200) by the rotating member (170) so that they are drained into the reservoir (1020) of the main body (100).

[0118] Meanwhile, the first body (2100) can be installed to be elastically supported by a spring (2300) and to be movable up and down, and the spring (2300) is installed on a support plate (2320) provided in the main body (100).

[0119] Thus, the first body (2100) is elastically supported by the spring (2300), and while the user's foot is received in the receiving portion (2020) of the first body (2100) and the second body (2200), the external force applied to the first body (2100) and the second body (2200) is supported by the spring (2300), and the user may also adjust the tilt of the first body (2100) and the second body (2200) to a comfortable angle.

[0120] At this time, the support force acting on the longitudinal front and rear of the first body (2100) can be varied to allow for adjustment to a more comfortable angle. This difference in support force can be achieved by varying the placement density of the springs (2300) at different locations or by arranging springs (2300) with different elastic forces.

[0121] In addition, the support plate (2320) is formed with a plurality of drainage holes (not shown in the drawing) so that the washing water and cleaning agent can be smoothly discharged downward along with the contaminants.

[0122] In addition, the washing water spray nozzle (2410) and the cleaning agent spray nozzle (2420) may be provided not only on the inner surface of the first body (2100) and the second body (2200) but also on the frame (2500a) on which the brush (2500) described later is installed, thereby allowing the washing water and cleaning agent to be evenly sprayed onto each part of the foot.

[0123] Meanwhile, the brush (2500) is installed at a position corresponding to each part of the foot so as to be able to rub each part of the three-dimensional foot.

[0124] That is, the brush (2500) may include a first brush (2520) corresponding to the sole of the foot, a second brush (2540) corresponding to the instep and toes, and a third brush (2560) corresponding to the heel.

[0125] At this time, the brushes (2500) may be installed in a fixed manner, or may be installed to be driven electrically by a driving means such as a motor, so that the user can manually rub them by moving their foot or clean them automatically.

[0126] More specifically, the first brush (2502) is installed at a position where the sole of the foot is supported on the bottom surface of the first body (2100) and the second body (2200), and may be installed in a fixed manner or configured to be electric so as to rotate in place or vibrate.

[0127] Additionally, the second brush (2540) is provided on the inner side of the second body (2200) and can be installed so as to be erected or withdrawn from the upper side.

[0128] That is, the second brush (2504) is rotatably installed on the frame (2540a), and the frame (2540a) is formed in a "U" shape, with both bent ends installed on the second body (2200), and the front part of the foot is positioned in the space between the second body (2200) and the second brush (2540).

[0129] At this time, the frame (2540a) may be manually raised or lowered by the user, or raised or lowered relative to the second body (2200) by a driving means such as a motor built into the second body (2200), so that the second brush (2540) may come into contact with the user's instep and toes, etc.

[0130] Afterwards, as the user moves back and forth with respect to the second brush (2540), the second brush (2540) can wash the upper part of the foot, such as the instep and toes.

[0131] In particular, as illustrated in FIG. 9(a), the second brush (2540) may be further equipped with a relatively long bristle (2550) in the middle, which enters between the toes to clean.

[0132] Additionally, although not illustrated, the frame (2540a) may be installed to be movable in the longitudinal direction of the second body (2200).

[0133] Therefore, when the frame (2540a) moves in the longitudinal direction of the second body (2200) while standing or pulled out, the second brush (2540) rubs the upper part of the foot, such as the instep and toes, so that the foot can be washed more comfortably.

[0134] At this time, the height of the frame (2540a) is continuously adjusted to correspond to the height from the top of the user's foot to the toes, so that the second brush (2540) can be maintained in contact with the upper part of the foot.

[0135] In particular, the end of the frame (2540a) coupled to the second body (2200) may be supported by an elastic member (not shown).

[0136] Therefore, when the foot is positioned in the space between the first body (2100) and the second brush (2540), as the elastic member (not shown) of the frame (2540a) extends, the height of the frame (2540a) is finely adjusted to match the height of the instep, thereby allowing the second brush (2540) to effectively maintain contact with the user's instep.

[0137] Additionally, the third brush (2560) is provided on the first body (2100) and can be provided to be able to stand up or be withdrawn upward relative to the first body (2100).

[0138] That is, as illustrated in FIG. 9(b), the third brush (2560) is rotatably installed on a frame (2560a), and the frame (2560a) is formed in a straight or "U" shape, with both bent ends installed on the first body (2100).

[0139] Of course, the configuration for standing up or pulling out the above frame (2560a) from the first body (2100) can be performed manually or electrically, as with the second brush (2540) described above.

[0140] Afterwards, the frame (2560a) can be repeatedly driven to stand up or extend by the driving means, or the user can wash the heel with the third brush (2560) by moving their foot directly.

[0141] In addition, the brush (2500) may further include a fourth brush (2580) corresponding to the toes to clean the toes more effectively.

[0142] The fourth brush (2580) is installed on the second body (2200), and the frame (2580a) may be formed in a straight line or a "U" shape, like the frame (2560a) of the third brush (2560), and may be provided to be able to stand up or be pulled out from the inner upper side of the second body (2200).

[0143] It goes without saying that the configuration for standing up or pulling out the frame (2580a) from the second body (2200) can be performed manually or electrically, as with the second brush (2540) described above.

[0144] In particular, the fourth brush (2580) may be further provided with a relatively long bristles (not shown) in the middle, similar to the second brush (2540), so that the bristles (not shown) of the fourth brush (2580) can enter between the toes to clean, or may be formed concavely in a shape corresponding to the outer shape of the toes so that not only the upper part of the toes but also the side part between them can be effectively cleaned.

[0145] Here, the first brush (2520), second brush (2540), brush head (2550), third brush (2560), and fourth brush (2580) may be formed in a form in which a brush head is equipped with a bristles or a sponge, and in particular, the third brush (2560) may be made of a rough material such as having micro-protrusions or micro-grooves formed therein to remove dead skin cells from the heel.

[0146] Meanwhile, it is preferable that the brushes (2500) are detachably installed on the first body (2100), the second body (2200), or the frame (2540a, 2560a, 2580a) so that they can be replaced in case of contamination or damage, thereby enabling more hygienic maintenance.

[0147] In addition, the control unit (140) can further clean the brush (2500) by spraying additional cleaning water when the cleaning of the foot is finished, thereby allowing the brush (2500) to be cleaned more cleanly.

[0148] Meanwhile, the smart foot washing device (50') according to the present invention may be in a form in which at least one of the first brush (2520), the second brush (2540), the third brush (2560), and the fourth brush (2580) is installed, and it is obvious that it can be formed in various combinations.

[0149] Additionally, the first brush (2520), second brush (2540), third brush (2560), and fourth brush (2580) may be fixed to the pad body (2100) or frame (2540a, 2560a, 2580a) so that the user can clean by moving their foot forward, backward, or sideways, or the brush head may be electric so that it rotates by a motor, etc., so that cleaning is performed by electric power.

[0150]

[0151] Meanwhile, as illustrated in FIGS. 10 to 12, the main body (100, 1000) and foot washing unit (200, 2000) of the smart foot washing device (50, 50') of the present invention may be equipped with a washing water moving pipe (310) and a washing agent moving pipe (320) through which washing water and washing agent supplied from the water supply pipe (110) and washing agent cartridge (120) of the main body (100, 1000) travel.

[0152] At this time, the washing water transfer pipe (310) and the cleaning agent transfer pipe (320) are formed of a flexible material so as not to be damaged when the foot washing unit (200, 2000) is folded or its length adjusted.

[0153] In addition, the washing water transfer pipe (310) and the cleaning agent transfer pipe (320) may be equipped with a valve or a small pump to control the supply of washing water and cleaning agent.

[0154] That is, the operation of the valve or small pump, etc. is controlled from the control unit (140) provided in the main body (100), and the supply status and amount of cleaning water and cleaning agent are controlled.

[0155] At this time, the main body (100) may further be provided with a sensor unit (150), and the sensor unit (150) may include a temperature sensor (152) and a flow rate monitoring sensor (154) for monitoring the temperature and flow rate of the washing water supplied to the washing water transfer pipe (310).

[0156] Therefore, the control unit (140) controls the operation of the valve or small pump of the washing water transfer pipe (310) based on the temperature and flow rate set according to the temperature and flow rate measurements of the temperature sensor (152) and the flow rate monitoring sensor (154).

[0157] In addition, as shown in FIG. 11, the cleaning agent cartridge (120) may be installed in combination of two or more types, and the mixing ratio of two or more cleaning agents supplied to the cleaning agent transfer pipe (320) can be controlled by adjusting the degree of opening and closing of the valve of each cleaning agent cartridge (120) and the output of the small pump by the control unit (140).

[0158] The above-mentioned washing water temperature, flow rate, and mixing ratio of the cleaning agent may be values ​​initially set during the manufacturing stage of the control unit (140), but it goes without saying that they may also be set by the user.

[0159] At this time, the main body (100) may be provided with a separate display and control unit for operating the power supply unit (130), control unit (140), and sensor unit (150).

[0160] In addition, the sensor unit (150) may further include a motion monitoring sensor (156) that monitors the user's movement. The control unit (140) determines that the smart foot washing device (50, 50') of the present invention is not in use when the user's movement is not detected by the motion monitoring sensor (156), and controls each component to a low-power standby mode to reduce the power consumption of the power supply unit (130). When the user's movement is detected by the motion monitoring sensor (156), the control unit (140) activates each component to automatically perform washing.

[0161] Meanwhile, the above-mentioned cleaning agent transfer pipe (320) is further provided with an air intake section (330), and a vibration mixing section (340) is provided to mix the air sucked in through the air intake section (330) with the cleaning agent so that the cleaning agent can be made into a foam form.

[0162] When the cleaning agent is discharged in the form of foam to the foot cleaning unit (200, 2000) described later, the abundant foam allows for gentler cleaning and rinsing with a small amount of water, thereby reducing water usage.

[0163] And, the above-mentioned cleaning agent transfer pipe (320) may further be provided with a vibrator (350) on a path adjacent to the cleaning agent spray nozzle (230, 2420).

[0164] The cleaning agent supplied in foam form through the cleaning agent transfer pipe (320) can be vibrated once more by the vibrator (350) just before spraying to make the cleaning agent foam denser and softer.

[0165]

[0166] Accordingly, the smart foot washing device (50, 50') according to the present invention as described above has various advantages, such as being foldable so that it is easy to store with a small volume when not in use, being unfolded to automatically wash the feet when in use, being configured as a two-stage foldable so that the volume can be further reduced when stored, being adjustable in length to correspond to foot size so that users with various physical conditions can wash their feet, being automatically supplied with washing water and a cleaning agent, being equipped with a brush corresponding to each part of the foot so that the feet can be washed automatically, being equipped with a replaceable brush so that it can be managed more hygienically, and being easy to replace the cartridge in which the cleaning agent is stored so that the cleaning agent can be used according to the user's preference or by changing the mixing ratio of the cleaning agent to suit the user's characteristics.
