Description

Sit-down toilet with foot health controller attached

The present invention relates to a toilet seat to which a foot health care device is attached.

A sitting toilet, which is used as if sitting on a chair, is also called a toilet or a toilet seat, and is one of the necessities that are used frequently and play an important role in daily life.

The toilet seat takes the form of sitting, and since it is mainly placed in the bathroom at home, it can be used in relation to rest or washing even when not toileting. Until now, it is difficult to find an example in which additional functions are commercialized and used other than toilet-related functions such as local washing.

On the other hand, an important and frequent act performed in a bathroom in daily life is foot washing. Feet are prone to dryness or roughness because they secrete three times more sweat than other body parts and have almost no sebaceous glands. If you do not take proper care of your feet, you may be at risk of getting various foot diseases such as athlete's foot.

In particular, when a pandemic virus is prevalent or air pollution is severe due to fine dust, you must keep your feet clean after going out to protect your health.

In general, when washing the feet, bend the back so that the hands can reach the feet and wipe every corner of the feet with the hands, but patients with herniated discs, pregnant women, or the elderly who have difficulty in this movement may have great difficulty washing their feet on their own because the movement itself is inconvenient, and they are not free from safety issues such as slipping.

Accordingly, conventional foot washing products may be placed around a toilet seat that serves as a chair so that users can safely wash their feet, or may be attached to and used in a toilet seat, but various unnecessary problems including drainage treatment remain.

For example, since a general sitting toilet is installed in close contact with the floor and has a structure that seals the installation portion to block odor, it is difficult to install a sewage pipe when attaching a foot washing product to the sitting toilet.

The present invention has been proposed to solve the above problems, and in order to secure an installation space for a foot health care device, the skirt portion located at the lower end of the existing toilet bowl is removed, and the lower part of the body (main body) is inserted into the lower part of the main body (main body) to secure the safety of the weak support. The purpose is to provide a toilet seat having a structure including a frame.

In particular, in order for the foot health care device to be stored under the toilet, the rear of the foot washing tank must be composed of a variable wall, and the present invention provides a method of configuring the variable wall by combining a waterproof wall having a waterproof function and a support wall supporting the waterproof wall.

In addition, when the foot health care device is stored or deployed, a method of preventing the variable wall from sagging or deforming due to the weight of the water contained in the washing tank is also provided by coupling a part of the variable wall with an electromagnet.

The problem to be solved by the present invention is not limited to the above-mentioned problems, and other problems not mentioned herein will be clearly understood by those skilled in the art from the following description.

A toilet seat according to an embodiment of the present invention includes a body including a toilet seat and a toilet bowl, a frame supporting a lower portion of the body, and a foot washing tank that is accommodated in the front lower portion of the body and the frame and can be unfolded and adjusted according to a separate operation. It includes a foot health care device.

The frame is detachable from the lower end of the main body and has a center of gravity at the rear.

The frame includes: a toilet seat support portion over which the toilet seat rim of the main body is crossed; and a plurality of support walls each extending downward from the side end of the toilet seat support unit.

The frame has sliding rails on the sliding movement section of the foot washing tank on the floor, and casters movable on the sliding rail are provided in some sections of the upper and lower sections of the foot washing tank.

Side covers may be disposed at both ends of the frame to airtightly protect the sliding movement section of the foot washing tub and to support the front of the main body.

The foot health care device includes a spray unit for spraying a predetermined amount of washing water toward the inner space of the foot washing tank; Washing water supply unit for supplying washing water to the spraying unit; a user input unit provided outside the foot washing tank to display the operating state of the foot health care device and to provide buttons for each function; and a control unit controlling the injection unit and the washing water supply unit according to the command of the user input unit.

The foot washing tank includes a variable wall that is folded inwardly of the foot washing tank when a rear wall facing the toilet bowl comes into contact with a lower end of the toilet bowl.

The variable wall may be formed by combining a support wall forming part or all of the wall of the foot washing tank and a waterproof wall that is combined with the support wall to waterproof the foot washing tank.

The support wall includes a plurality of support filler members positioned at both ends of the rear end of the upper end of the foot washing tub; and a support folding plate that is folded or unfolded between the plurality of support pillar members and maintains a flat structure when there is no external force due to an elastic action.

The waterproof wall is generally preferably made of an elastic material, and the support wall is preferably made of an inelastic material.

The waterproof wall is preferably airtight by surrounding the support filler member and the support folding plate inside the foot washing tank.

The waterproof wall is a waterproof filler member bonded to the inside of the supporting filler member; Waterproof folding plate bonded to the inside of the support folding plate; and a folding member connecting between the waterproof filler member and the waterproof folding plate and capable of radially folding.

The folding member may be made of a folding method in which a plurality of rubber plates are folded.

The folding member is made of a folding method in which a plurality of rubber plates are folded, and includes a magnetic body disposed at each folded portion.

At this time, power may be applied to the magnetic body such that the folding member is folded when the foot washing tank is deployed and unfolded when the foot washing tank is accommodated in the storage space of the main body.

The foot washing tank includes a sewage inlet pipe connected to the sewage pipe of the toilet; It is disposed on the sewage inlet pipe and includes an odor blocker composed of a U-shape or a motorized valve to block odors flowing from the sewage pipe of the toilet.

The foot washing tank of the foot health care device may further include a toe washing unit for washing between the user's toes in the inner space.

The toe washing unit includes a toe spray nozzle for spraying washing water toward between the user's toes, and a cleaning member attached to the outside of the toe spray nozzle to remove contaminants caught between the user's toes.

According to the present invention, it is possible to solve the problem of space limitations by storing the foot health care device in the storage space located at the lower front.

In particular, through the frame installed on the lower part of the main body (main body), the support safety can be secured even if the skirt part of the existing toilet bowl is removed, and the installation space for the foot health care device can be secured.

In particular, by placing the foot health care device at the lower end of the wall-attached toilet seat, there is an extra space at the bottom of the toilet tank, so that the foot washing tank can be installed more easily.

In addition, in order for the foot health care device to be stored under the toilet, the rear of the foot washing tank must be composed of a variable wall. The present invention provides a method in which a waterproof wall having a waterproof function and a support wall supporting the waterproof wall are combined and configured, thereby greatly increasing the durability of the variable wall, strengthening the waterproof function, and making maintenance easy.

In addition, it is possible to wash the toes in the foot washing tank of the foot health care device added to the sitting toilet in a comfortable sitting position, and the sewage in the foot washing tank can be discharged through the sewage outlet on the toilet floor without inflow of smell.

Therefore, with the foot health care device attached to the toilet seat according to the present invention, the user can conveniently discharge sewage without worrying about inflow of odor while washing cleanly between the toes, enabling foot washing and foot bathing in a very comfortable environment.

In addition, the present invention can provide convenience and practicality by configuring the seat toilet cover to be used by the user as a chair.

In addition, the present invention has a structure that can evenly wash the soles of the feet and between the toes without bending the waist and without using hands, so that even people with limited mobility can comfortably wash their feet and take a foot bath.

However, the present invention is not limited to the embodiments disclosed below, but will be implemented in a variety of different forms, and only these embodiments make the disclosure of the present invention complete, and those skilled in the art are provided to fully inform the scope of the invention, and the present invention is defined by the description of the claims. Meanwhile, terms used in this specification are for describing the embodiments and are not intended to limit the present invention. In this specification, singular forms also include plural forms unless specifically stated otherwise in a phrase. As used herein, "comprises" or "comprising" does not exclude the presence or addition of one or more other components, steps, operations and/or elements other than the recited components, steps, operations and/or elements.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 6 schematically show a toilet seat according to an embodiment of the present invention.

1 to 6, the toilet seat 10 includes a foot health management device 100, a main body 200 and a frame 300.

Basically, the main body 200 in the form of a toilet seat 10 has a storage space at the lower front portion, and the foot health management device 100 is attached to the storage space so that it is deployed to the outside or stored inside.

The main body 200 constituting the frame of the toilet seat 10 has a toilet tank 220 formed from a front upper end to a rear lower end, and a seat toilet sewage pipe (not shown) is installed at the lower end.

The frame 300 is a skeleton made of iron supporting the lower portion of the main body 200 . The frame 300 is detachable from the lower end of the main body 200 and has a center of gravity at the rear to prevent the toilet seat 10 from leaning forward even when the user is sitting on the toilet seat.

Outer walls 211 for airtightly protecting the sliding movement section of the foot washing tank 110 and supporting the main body 200 may be disposed in some sections of both ends of the main body 200 except for the front side. The outer wall 211 may be integrally formed with the main body 200 in a state of being disposed outside the foot washing tub 110 or may be formed as a separate type.

Here, the outer wall 211 surrounds both ends of the foot washing tank 110 to support the front end of the main body 200 on the floor, and distributes the load received by the front end of the main body 200 when the user sits on the toilet seat 10.

Accordingly, the outer wall 211 can block the possibility of being damaged by the load applied to the front end of the toilet seat 10 in advance.

Conventional toilet seats (not shown) have a skirt at the lower front to prevent the main body from leaning forward even when the user is sitting on the toilet seat, but due to the skirt, a separate device is stored at the lower front, such as the foot health care device 100. There was a structural limitation inevitably being constrained on the installation space.

In order to solve this, the present invention, instead of eliminating the conventional skirt portion, puts a frame 300 made of iron at the bottom of the main body 200 constituting the main body to secure the installation space of the foot health care device 100 in the front storage space. It is possible to prevent the phenomenon of leaning forward.

The frame 300 may be structurally formed integrally through welding or fastening a separate bracket (not shown). The frame 300 includes a toilet seat support 310, a plurality of support shafts 320, and a floor panel 330.

The toilet seat support part 310 is a part where the toilet seat rim of the main body 200 spans.

As shown in FIGS. 3 and 5, the toilet seat support part 310 has a stepped structure with first and

second support parts

311 and 312, but since it essentially functions as supporting the body 200 of the toilet seat 10 from the lower part, the shape of the toilet seat support part 310 does not need to be limited thereto. For example, the toilet seat support 310 has a flat or inclined structure rather than a stepped structure, so that the main body 200 can be firmly supported.

The plurality of support shafts 320 are formed to extend downward from the side ends of the toilet seat support part 310 to form the frame 300 and form a plurality of shafts to effectively support the main body 200 .

The bottom panel 330 is connected to lower ends of the plurality of support shafts 320 and forms the bottom of the frame 300 . A sliding rail 331 and a drainage hole 332 are formed on the bottom panel 330 .

The sliding rail 331 provides a moving section of the foot washing tub 110. Here, the foot washing tub 110 may include casters (not shown) movable on the sliding rail 331 in some sections of the upper and lower sections.

A stopper (not shown) may be provided on the sliding rail so that the foot washing tub 110 can be stably stopped at every unit length.

The foot washing tub 110 may have a structure that slides and moves electrically through an electric linear actuator (not shown) provided in the main body 200, and of course may have a structure that slides manually as another embodiment.

As another example, an elastic member (not shown) such as a spring is connected to the connection between the upper and lower ends of the foot washing tub 110 and the inside of the main body 200 so that the user can manually open and close the foot washing tub 110 from the main body 200 with less effort, like opening a drawer in a chest of drawers. At this time, the foot washing tub 110 has a structure that is returned to its initial position by an elastic member, but when a user performs foot washing or foot bath, the foot washing tub 110 needs to be fixed at the corresponding position.

In this case, stoppers disposed for each unit length of the sliding rail may fix the foot washing tub 110 to a corresponding position. For example, fixing holes (not shown) are formed for each unit length of the sliding rails disposed at both ends of the upper and lower ends of the main body 200, and the stoppers pass through the left and right sides of the sliding rails with the fixing holes interposed therebetween.

When the foot washing tub 110 of the foot health care device 100 is repeatedly slid from the storage space of the main body 200, an impact is applied to the contact portion and there is a risk of abrasion to the corresponding portion.

Meanwhile, the lower end of the toilet cistern 220 formed in the body 200 affects the height of the foot washing cistern 110 .

When the height of the foot washing tank 110 is low, the lower end of the toilet tank 220 does not affect the storage of the foot washing tank 110, but a problem may occur when the foot washing tank 110 needs to be raised (for example, when the toilet tank is a siphon type, the toilet tank sag downwards and the foot washing tank needs to be raised).

That is, when the foot washing tank 110 is accommodated in the front lower end of the main body 200, the foot washing tank 110 may be caught on the lower end of the toilet bowl 220. In order to avoid this, the main body 200 has to secure more front space to accommodate the foot washing tank 110 or the foot washing tank 110 cannot be accommodated in the main body 200 and protrudes. To solve this problem, the variable wall 112 is required. When the foot washing tank 110 of the foot health care device 100 is stored at the lower end of the main body 200, the variable wall 112 is folded inward as much as it comes into contact with the toilet tank 220, so it can be stored at the lower end of the main body 200 without any problems.

As shown in FIG. 4, the variable wall 112 includes a support wall 113 and a waterproof wall 114.

The support wall 113 forms a wall at the rear of the foot washing tub 110 and is made of an inelastic material such as aluminum and/or reinforced plastic.

The support wall 113 includes a support pillar member 113a and a support folding plate 113b.

The support filler members 113a are located at both ends of the rear end of the upper end of the foot washing tub 110, respectively.

The support folding plate 113b is folded or unfolded between the plurality of support filler members 113a, but maintains a flat structure when there is no external force due to an elastic action.

To this end, the hinge member 113c, the spring wire 113d, and the fixing clip 113e may be connected to the folding support plate 113b.

For example, the hinge member 113c is located at the lower end of the folding support plate 113b, and a spring wire 113d is connected therebetween so that the folding support plate 113b can have a flat structure by an elastic action.

The fixing clip 113e serves to fix the spring wire 113d to the folding support plate 113b.

The waterproof wall 114 has a function of enclosing the support filler member 113a and the support folding plate 113b inside the foot washing tub 110 to make them airtight, and may be made of a rubber material capable of elasticity.

Here, the rubber material includes natural rubber and synthetic rubber, and among them, it may be made in the form of one of silicone, urethane, and latex.

In particular, since latex is a material in which fine polymer particles are dispersed in an aqueous solution and is one of the widely used materials, it may be more usable depending on the use and environment.

The waterproof wall 114 includes a waterproof filler member 114a, a waterproof folding plate 114b and a folding member 114c.

The waterproof filler member 114a is bonded to the inside of the support filler member 113a.

The waterproof folded plate 114b is bonded to the inside of the support folded plate 113b.

The folding member 114c connects between the waterproof filler member 114a and the waterproof folding plate 114b, and a radial folding operation is possible.

The sewage inlet pipe (not shown, the horizontal pipe at the front end of the U-pipe) is connected to the sewage outlet of the foot washing tank 110, and has the main body 200 and each drain pipe and penetrates the wall.

The odor blocker (not shown) is disposed between the sewage inlet pipe and the sewage pipe to block odor from flowing in from the sewage outlet on the bathroom floor. That is, the odor blocking unit can be implemented as a U-shaped pipe or a dedicated valve to block odor flowing from the sewage outlet on the bathroom floor.

The sewer pipe (not shown, vertical pipe at the rear end of the U-pipe) may have a front end connected to the odor blocking unit and a rear end connected to a sewage outlet on the toilet floor or a trap in the toilet tank.

The foot health care device (FIG. 1 100) periodically discharges clear water to fill the odor blocking unit. This is also part of preventing water from pooling in the U-shaped odor blocking part. Therefore, the periphery of the odor blocking unit must be sealed.

7 to 9 schematically show an example in which the inner wall of the foot-washing tank 110 is elastically deformed through a magnetic material, and detailed configurations of the foot-washing tank 110 (shown through the drawings to be described later) are not shown.

Therefore, FIGS. 7 to 9 are only views showing that the variable wall 112 of the foot washing tank 110 is made of an elastically deformable material, and the shape of the foot washing tank 110 is not limited due to the illustrated form.

As described above, the variable wall 112 shown in FIGS. 7 to 9 has a structure in which a support wall (113 in FIG. 4 ) and a waterproof wall 114 are combined. The waterproof wall 114 is made of, for example, a latex rubber material and can be elastically deformed. At this time, the portion where the waterproof wall 114 is connected is airtight so that water does not leak even when the user performs foot washing and foot bath using the foot washing tub 110 .

To this end, a folding member 114c is provided between the waterproof filler member 114a of the waterproof wall 114 and the waterproof folding plate 114b. The folding member 114c is made of a folding method in which a plurality of rubber plates are folded, and airtightly connects between the waterproof filler member 114a and the waterproof folding plate 114b bonded to the inside of the support filler member 113a and the support folding plate 113b.

Here, the plurality of rubber plates include the first rubber plate 114c_1, the second rubber plate 114c_2, and the third rubber plate 114c_3. As shown in the figure, the folding member 114c has a form in which the first, second, and third rubber plates 114c_1, 114c_2, and 114c_3 are connected to each other, but this is only one example. may be done In this specification, the first, second, and third rubber plates 114c_1, 114c_2, and 114c_3 will be specifically described in order to help understand a structure in which a plurality of rubber plates overlap each other.

The folding member 114c may include a magnetic body 115 embedded in the first, second, and third rubber plates 114c_1, 114c_2, and 114c_3. The magnetic material 115 may be an electromagnet that is magnetic only when power is applied from the outside. The magnetic material 115 may be embedded in the first, second, and third rubber plates 114c_1, 114c_2, and 114c_3 so that attractive force and/or repulsive force act on each region where the rubber plates 114c_1, 114c_2, and 114c_3 face each other.

For example, after the foot washing tank 110 is fully deployed, the control unit 140 may output a signal for controlling the power of the power supply unit 180 (the seat toilet may have a separate sensor (not shown) for detecting the opening and closing of the foot washing tank.).

The magnetic material 115 in FIG. 7 can function only as a form in which attraction is applied by being supplied with power by the power supply unit 180 . At this time, the magnetic body 115 embedded in each of the first, second, and third rubber plates 114c_1, 114c_2, and 114c_3 may be disposed in such a way that N poles and S poles are in contact so that attractive force acts at positions facing each other.

As another example, the magnetic material 115 in FIG. 8 may be embedded in the first, second, and third rubber plates 114c_1, 114c_2, and 114c_3 while being spaced apart along the vertical length direction of the waterproof wall 114.

Here, for convenience of description, the magnetic body 115 is described in the same way as 1 row from the top of the waterproof wall 114 in FIG. 8, the next lower row is 2 rows, and the next lower row is 3 rows.

In the magnetic body 115, for example, the N pole and the S pole are alternated in the forward and backward directions along the vertical length direction of the waterproof wall 114, so that only the first and third rows of magnetic bodies 115 generate attraction or repulsive force according to the selective operation of the user input unit 130, or, conversely, only the magnetic bodies 115 in the second and fourth rows generate attraction or repulsion, so that the foot washing tank 110 is deployed or stored selectively. Allows you to adjust that function.

For example, when the foot washing tank 110 is deployed, since the waterproof wall 114 must have a closed structure as the rear wall of the foot washing tank 110, the folding member 114c has a hard form by the attraction of the magnetic body 115 embedded in the first, second, and third rubber plates 114c_1, 114c_2, and 114c_3. to function as a wall.

On the other hand, when the foot washing tank 110 is accommodated in the front storage space of the main body (200 in FIG. 1), the folding member 114c makes the waterproof wall 114 variable according to the shape of the lower end of the toilet tank 220 by the repulsive action of the magnetic body 115, thereby facilitating the storage of the foot washing tank 110.

The magnetic material 115' in FIG. 9 is formed long along a partial vertical section of the top of the waterproof wall 114 to further improve adhesion between the first, second, and third rubber plates 114c_1, 114c_2, and 114c_3.

On the other hand, the rear lower end of the foot washing tank 110 may be connected to a lower part of the rear wall of the foot washing tank 110 so that the variable wall 112 rotates and inclines into the inner space when the foot washing tank 110 is stored or deployed. Here, the lower rear portion of the foot washing tub 110 has a closed structure so that water does not leak to the outside when the user uses the foot washing tub 110 and performs foot washing or foot bathing.

After all, the height of the variable wall 112 should be adjusted so that the foot washing tank 110 is inserted into the front lower end of the toilet seat (10 in FIG. 1), and the height of the variable wall 112 should be adjusted so that the height of the variable wall 112 increases when the user slides it forward from the toilet seat (10 in FIG.

10 and 11 are cross-sectional views schematically showing an example of operation of the foot health management device according to an embodiment of the present invention from the front and rear.

Referring to FIGS. 10 and 11, the foot washing tank 110 can contain an electronic circuit board capable of driving the foot health management device 100 and related parts in a confidential manner. Parts such as various cables, sensors, actuators, switches, and LEDs are also included, and various parts connected thereto are included.

The foot washing tub 110 has a structure in which the user's feet are accommodated, and a washing plate 111 on which the user's feet are placed is provided on the bottom plate.

The washing plate 111 is based on a flat surface, but may be modified to have a central portion protruding upward (a portion where the arch of the foot is located).

A plurality of protrusions 111a protruding upward may be disposed at intervals on the washing plate 111 .

The protrusion 111a effectively helps to wash the soles of the feet and serves to maintain a certain distance between the foot and a nozzle (upward spray nozzle 124) formed on the floor or the floor. It is preferable that the protrusion 111a has a shape in which the feet can be rubbed and wiped while providing an acupressure effect by feeling a rough touch when touching the sole of the foot.

On the other hand, the protrusion 111a may be elastically deformed or depressed at the bottom where the foot is placed to serve as a frame to hold the shape of the foot, so that the foot may be stably seated on the washing plate 111.

The washing plate 111 has a detachable structure from the foot washing tank 110 and can be configured to be used interchangeably. Alternatively, it may be an area where a protrusion is formed on the bottom surface of the foot washing tank 110 and the foot is placed, that is, a part or all of the bottom surface of the foot washing tank 110.

The cover (not shown) of the foot washing tank may cover a section (front part) of the upper surface of the foot washing tank 110 to prevent water from splashing out, and may provide an area where a downward spray nozzle 122 to be described later is installed.

The cover of the foot washing tank may have a structure that is detachable from the foot washing tank 110, or may have a structure that is rotatable by connecting a hinge shaft (not shown) to one side of the front end of the foot washing tank 110.

The spraying unit 120 sprays washing water toward the inner space of the foot washing tub 110 . The wash water is essentially water, but may include a wash liquid.

The spraying unit 120 includes a side spray nozzle 123 and an upward spray nozzle 124, and may optionally include a downward spray nozzle 122 formed on the lower surface of the foot washing tank cover.

One or more side spray nozzles 123 are disposed on the inner circumferential surface of the foot washing tub 110 to spray water to the side. The side spray nozzle 123 sprays water from a position installed on the inner wall of the foot washing tank 110 to a position lower than the horizontal direction.

Since the washing water is sprayed from left and right inside the foot washing tank 110, the soles of the feet may be wiped by twisting the ankle.

Meanwhile, the front end of the bottom of the foot washing tub 110 may be formed higher than the height of the rear end, and the position of the side spray nozzle 123 toward the toes may be formed higher. In this way, the direction of the sprayed washing water becomes more vertical, so that the instep and toe washing can be performed more effectively.

The upward spray nozzles 124 are disposed on the bottom surface of the washing plate 111 at intervals to spray water upward to wash the soles of the feet.

At this time, the spray pressure of the upward spray nozzle 124 is preferably configured such that the height of the sprayed washing water is maintained within the height of the foot washing tub 110 to prevent the washing water from splashing out of the foot washing tub 110 . Alternatively, when washing the soles of the feet, the spray pressure of the upward spray nozzle 124 may be increased, and the spray pressure may be adjusted to be weak immediately upon sensing that foot is removed from the washing plate 111 .

One or more downward spray nozzles 122 are disposed inside the cover of the foot washing tank to spray washing water downward. When the downward spray nozzle 122 is additionally provided, it is effective in washing the instep and toes.

An external washing water supply unit (160 in FIG. 13) and/or a cleaning liquid supply unit (not shown) are connected to the spray unit 120. Although the washing water is supplied through an external water supply pipe, a water tank (not shown) may be provided to store the washing water inside the foot washing tank 110 in order to adjust the spray pressure. For example, when the water pressure in the water supply pipe is higher than necessary, the water tank part acts as a buffer to maintain the proper injection pressure, and when the washing water injection pressure needs to be greater than the water pressure in the water supply pipe, a piston (not shown) connected to the water tank part operates to increase the injection pressure.

The cleaning solution supply unit may receive the cleaning solution from an external cleaning solution supply device (not shown) or may be of a cartridge replacement type. The washing liquid supply unit is connected to the washing liquid nozzle 125 . As another embodiment, the washing liquid supply unit may be connected to each nozzle of the spraying unit 120 so that each nozzle of the spraying unit 120 sprays the washing liquid alternately with the washing water or mixed with the washing water to spray the washing liquid.

That is, the downward spray nozzle 122, the side spray nozzle 123, the upward spray nozzle 124, and the washing liquid nozzle 125 are connected by one pipe, and a spray valve (not shown) is provided at each branched part, so that washing water and / or washing liquid can be selectively sprayed.

Alternatively, for structural convenience, only the downward spray nozzle 122 and the washer liquid nozzle 125 are connected by a single pipe, and a spray valve is disposed between them to selectively spray the washing water and/or the washing liquid.

The operation of the injection unit 120 is controlled by the controller (140 in FIGS. 6 to 8 and 12) according to a user input through the user input unit (130 in FIGS. 6 to 8 and 12) or according to a predetermined control logic.

At this time, in order to prevent water from splashing to the outside of the foot washing tank 110, the injection unit 120 is preferably sprayed while a predetermined amount of water disposed inside the foot washing tank 110 is filled. Here, the preset predetermined amount can be measured by the height at which the washing water inside the foot washing tub 110 is filled in advance, which can be changed according to the environment.

The spray pressure, spray pattern, and spray angle of the washing water and/or cleaning liquid sprayed by the spray unit 120 may be variously combined or controlled, which will be described later.

The injection unit 120 may be displayed as ON/OFF of power by an LED (not shown) electrically connected to the user input unit (130 in FIGS. 6 to 8 and 12).

12 is a view schematically showing an example of an operation of a bubble generating unit in a wall-mounted toilet seat with foot health management attached according to an embodiment of the present invention.

Referring to FIG. 12, the foot health care device (100 in FIGS. 9 and 10) is disposed on the bottom (bottom of the washing plate) of the foot washing tank (110 in FIGS. 9 and 10) to generate bubbles toward the soles of the user's feet. It may further include a bubble generator 190.

If washing water is sprayed into the corresponding section while bubbles are generated, the resistance of the water is weakened, so the washing power can be increased, and the user can feel a sense of refreshment due to the bubbles.

The bubble generating unit 190 adjusts the flow rate and bubble shape of the blown gas so as to obtain optimal contact efficiency when gas is absorbed or reacted by contacting a solid or liquid.

13 is a view schematically showing a toe spray nozzle in a wall-mounted toilet seat with foot health management attached according to an embodiment of the present invention.

Referring to FIG. 13, a toe injection nozzle 171 may be further disposed in the foot health care device.

The toe spray nozzles 171 are disposed at intervals in the width direction of the washing plate 111 so as to be located between the toes of the feet seated on the washing plate (111 in FIGS. 10 and 11) in the longitudinal direction, and spray water toward the toes.

The toe spray nozzle 171 is located between the toes, and may be formed in a form in which the width is adjusted left and right or the length is adjusted vertically based on the toe shown in FIG. 15 .

The toe injection nozzle 171 is formed in a cylindrical shape and has a plurality of injection ports 171a on the outer surface. The toe spray nozzle 171 is connected to the washing water supply unit 160 and has a function of spraying washing water to the outside. Washing water supplied from the washing water supply unit 160 is sprayed to the outside (between the user's toes) through the plurality of spray holes 171a.

As shown, the toe injection nozzle 171 is made of a column shape, but the toe injection nozzle 171 is made of a tapered shape in which a part of the upper end becomes wider from the top to the bottom, so that the toe is easily inserted. It may be made of a structure.

The toe spray nozzle 171 may be raised and lowered, and may be configured to spray water while rotating.

Since each person using the foot health care device 100 according to the present invention has a different shape and size of toes, the toe spray nozzle 171 is the width (and/or length) of the washing plate 111 according to the shape of the toe of the user so that it can be applied to an unspecified number of people. It is possible to move the position by a predetermined length (installation interval) in the direction.

The position movement of the toe spray nozzle 171 for each user is stored in a storage device (not shown), and later moved to the stored position for each user by simple manipulation of the user input unit (130 in FIGS. 6 to 8 and 12). Can be configured. For example, when two people A and B with different toe sizes and shapes use the foot health care device 100, A manipulates the user input unit (e.g., button 1 is pressed) to automatically move the toe spray nozzle 171 to a position suitable for A's toe, and B manipulates the user input unit (e.g., presses button 2) so that the toe spray nozzle 171 can automatically move to a position suitable for B's toe.

Hereinafter, the operation and control of the foot health management device (100 in FIGS. 1, 4 and 5 and 10 to 11) according to the present invention will be described. All electrical/electronic devices of the foot health management device 100 according to the present invention, including the above-described injection unit 120, the washer nozzle 125, and the user input unit (130 in FIGS. 6 to 8 and 12) are controlled by a control unit (not shown).

First, injection pressure and injection operation control will be described in detail.

The foot health care device 100 according to the present invention can be controlled so that each injection nozzle is sequentially injected in order to maintain the injection pressure of each injection nozzle at a certain level or higher. For example, the upward injection nozzle 124 - the side injection nozzle 123 - the toe injection nozzle 171 are operated in order to maintain the injection pressure above a certain level. If necessary, a pressurizing pump (not shown) may be used to increase the injection pressure, and if an appropriate injection pressure can be maintained, it can be controlled to be sprayed simultaneously from two or more nozzles.

On the other hand, in order to increase the washing and massage effect, each nozzle may be controlled to spray with a spray pressure that varies according to time.

Various combinations of spraying methods of washing water and washing liquid are possible. For example, when the spraying unit 120 sprays the washing water, the water and the washing liquid may be sprayed from the same nozzle alternately or according to a predetermined spray pattern, and the washing water mixed with the water and the washing liquid may be sprayed, or only water may be sprayed. Alternatively, the washing liquid may be controlled to be sprayed only from a dedicated nozzle (washing liquid nozzle) 125 .

In order to increase the washing effect and massage effect, each nozzle of the spraying unit 120 can adjust the spraying angle left/right or up/down, and the side spray nozzle 123 and the upward spray nozzle 124 are preferably limited within a predetermined range so that water does not splash out of the foot washing tank 110.

Control of the injection pressure, injection method, and injection angle is performed by a user operation through a user input unit (130 in FIGS. 6 to 8 and 12) or a control unit (140 in FIGS. 6 to 8 and 12) according to a preset control logic.

14 is a view schematically showing an example of an operation of a toe washing unit in a wall-mounted toilet seat with foot health management attached according to an embodiment of the present invention.

Referring to FIG. 14, the toe washing unit 170 includes a toe spray nozzle 171, a cleaning member 172, and a rotating piece 173.

A cleaning member 172 may be rotatably mounted on an upper portion of the toe spray nozzle 171 . The cleaning member 172 has a cylindrical shape with an open lower surface. The rotating piece 173 is positioned on top of the cleaning member 172 and can rotate coaxially with the cleaning member 172 .

In the toe washing unit 170, the cleaning member 172 coupled with the rotating piece 173 covers an upper portion of the toe spray nozzle 171 and rotates in the axial direction to wash between the toes. That is, the cleaning member 172 has a structure that rotates in conjunction with the rotating piece 173 when the rotating piece 173 is rotated by the washing water sprayed from the spraying unit 120 .

Since the cleaning member 172 is a part that directly touches the skin to remove foreign substances including various dead skin cells between the toes, it may be made of a rubber type made by foaming an undiluted solution of natural rubber or a hard sponge made of urethane type made of synthetic resin. A plurality of protrusions may be formed on the outer circumferential surface of the cleaning member 172 at intervals.

Here, a bearing (not shown) may be provided between the inner circumferential surface of the cleaning member 172 and the outer circumferential surface of the toe spray nozzle 171 to assist rotation of the cleaning member 172 .

15 to 18 are diagrams schematically illustrating a modified example of operation of a toe washing unit in a wall-mounted toilet seat with foot health management attached according to an embodiment of the present invention.

The cleaning member 172' shown in FIGS. 15 to 18 has a cylindrical shape with an open lower surface, and is axially rotatable while covering the outside of the toe spray nozzle 171'. However, the cleaning member 172' in FIGS. 15 to 18 has a rotation method different from that of the above-described embodiment.

Before explaining this rotation method, the structure of the toe spray nozzle 171' and the cleaning member 172' will be described.

As shown in FIG. 16, the toe spray nozzle 171' has a structure capable of rotating in the inserted state of the cleaning member 172'.

To this end, the toe spray nozzle 171' has a washing water guide groove 171b', a spray hole 171a', and a rotating shaft 171c'. The washing water guide grooves 171b' are recessed at intervals along the longitudinal direction on the outer circumferential surface of the toe spray nozzle 171'. The spray holes 171a' are formed through the washing water guide grooves 171b' at intervals. The rotating shaft 171c' is connected to the rotating shaft connecting groove 172b' formed on the inner surface of the cleaning member 172'.

The cleaning member 172' has a plurality of injection ports 172a communicating with the injection ports 171a' of the toe injection nozzle 171'.

17(a) is a view showing a BB′ cross section of FIG. 15, and (b) is an example in which the cleaning member cover 174′ is added in (a). Referring to (a) and (b) of FIG. 17 , the injection hole 172a' has a structure passing obliquely with respect to the axial center of the cleaning member 172'.

The spray hole 172a' of the cleaning member 172' has a structure connected to the washing water guide groove 171b' of the toe spray nozzle 171'.

Here, the washing water guide groove 171b' is a space through which water flows, and has a function of continuously spraying the washing water flowing into the washing member 172' through the toe spray nozzle 171' to the outside without interruption.

As shown in FIG. 18, when the washing water supplied from the washing water supply unit 160 is sprayed to the spray hole 172a' through the spray hole 171a' of the toe spray nozzle 171', the spray hole 172a' induces the rotation of the cleaning member 172' by the spray pressure.

Since the washing member 172' has a structure in which washing water is rotated by the force ejected through the injection hole 172a', if it is made of soft material, it may not rotate between the user's toes. Therefore, the cleaning member 172' is made of hard material within a rotatable range, and a plurality of protrusions may be formed on the outer surface to assist in cleaning.

The cleaning member cover 174' can be replaced in a form fitted to the outer circumferential surface of the cleaning member 172'. That is, the cleaning member cover 174' is made of a replacement type to maintain cleanliness because the contact surface may be contaminated when removing contaminants between the user's toes. At this time, it is preferable that the cover hole 174a' of the cleaning member cover 174' communicates with the spray hole 172a'.

In the toe washing unit 170', one or more toe washing nozzles 171' are disposed between each user's toes, extending vertically upward, and washing and massaging between the toes through rotation.

It is preferable to place one or more protrusions on the outer circumferential surface of the cleaning member 172' surrounding the toe washing nozzle 171' to increase the washing power and massage effect, and the body of the cleaning member 172' itself is hard, but the protrusions are soft.

Hereinafter, a preferred embodiment of the automatic washing operation of the foot health care device 100 according to the present invention will be described.

The automatic washing function may include a step of detecting foot placement, a step of spraying washing liquid, and a step of washing feet. The step of detecting foot placement is a step of detecting that the foot is placed on the washing plate 111 . The washer spraying step is a step in which the control unit receives the position information value of the foot detected by the foot detection sensor (not shown) and sprays the washer liquid by driving the washer nozzle 125 of the spraying unit 120 . The foot washing step is a step of washing the feet by spraying water from a water spray nozzle unit when a first waiting time elapses after the washing liquid is sprayed.

Optionally, a foot separation detection step in which the foot detection sensor detects that the foot has fallen from the washing plate 111, and an internal washing step in which washing water is sprayed from the injection unit 120 to clean the inner space of the foot washing tank 110 after the second waiting time has elapsed may be added.

Here, the first and second waiting times mean preset times in the corresponding process, and the corresponding times can be changed by the user.

The user may make various preset settings using the user input unit ( 130 of FIGS. 6 to 8 and 12 ). Basic values such as the spray pressure of the spraying unit 120, the first waiting time and the second waiting time of the automatic washing function, and the washing liquid spray amount may be set.

The step of detecting foot placement is performed by a foot detection sensor.

The foot detection sensor may be implemented by installing a light receiving unit (not shown) and a light emitting unit (not shown) on the left and right inner walls of the foot washing tub 110 or by placing a pressure sensor on the bottom of the washing plate 111.

The foot detection sensor detects a position where the foot approaches the washing plate 111 or a pressure value at which the foot is seated, and transmits the information value to the control unit. The control unit is electrically connected to the foot detection sensor, compares the information value transmitted from the foot detection sensor with a preset reference value, and controls driving of the injection unit 120 when the result value meets the reference value.

In the foot washing step, the control unit controls the injection unit 120 to automatically clean the inner receiving space of the foot washing tub 110 for a preset time. Here, the preset time is a time calculated based on statistical values accumulated from various data, and the initial set value may be different according to each function, and the set value may be determined by the user. In order to increase the effect of foot washing, the spraying method, spraying pressure, and spraying angle of the washing water and washing liquid may be automatically varied according to a user input or preset logic.

The internal washing step proceeds when the user who has finished washing his feet removes his feet. When it detects that the feet fall from the washing plate 111, the spraying unit 120 is stopped being driven by the control unit, and the control unit controls the spraying unit 120 to clean the inside of the foot washing tub 110 using the automatic washing function.

To wash the inside of the foot health care device 100, the control unit sprays the washing water toward the washing plate 111 for a preset time by adjusting the spray angle. The setting time can be arbitrarily changed by the user. Alternatively, the washing time of the washing plate may be changed until an appropriate level of washing is achieved by detecting the degree of washing of the washing plate by using a contamination sensor (not shown).

The washing water sprayed in the internal washing step may be a mixture of washing liquid having stronger washing power than washing water when washing the feet. To this end, the washing liquid storage unit may be configured to store the washing liquid for washing the washing plate separately from the washing liquid for washing the feet.

Above, the configuration of the present invention was examined in detail through several preferred embodiments. The present invention is composed of a structure that can evenly wash the soles of the feet and between the toes without bending the waist and without using hands, so that even people with limited mobility can wash their feet comfortably.

In addition, the foot health management device can solve the conventional management problem by being equipped with a function of automatically washing the device after foot washing and foot bathing. At this time, the foot health care device in which the user's feet are washed and foot bathed may eradicate bacteria or remove moisture by configuring an ultraviolet lamp (not shown) or a drying device (not shown) inside the cover of the body part.

Of course, the present invention is not limited to the above-described embodiments, and can be practiced with various modifications within the permitted scope of the technical spirit of the present invention.

As described above, the embodiments of the present invention, in addition to functioning as a toilet seat in a small space, can also serve as foot washing and massage by attaching a foot health care device.
