Description: FOOT MASSAGE APPARATUS TECHNICAL FIELD The present invention relates to a foot massage apparatus, and in particular to a foot massage apparatus which is capable of performing various massages such as an acupressure massage, a cold-water massage, a hot- water massage, a massage with medicine added, etc. efficiently by including a bottom surface jet means installed inside a main body, an intermittent jet head for intermittently jetting water toward the upper surface and bottom surface of a user's feet, an upper casing and a lower casing angle-adjustably coupled to each other, an acupressure roller installed at a center portion of a footstool, an aromatic agent jet means and a hot-air drying means, a heater installed between a detachable water vessel and a pump, and an input tube for depositing ice, salt, various medicines, etc. into the detachable water vessel installed at a lower casing of the main body. BACKGROUND ART Generally, a foot massage apparatus using air bubbles in an underwater state or a vibrator is widely known. A foot massage apparatus using an air-bubble generator is convenient for using a liquid medicine but has little massage effect, and a foot massage apparatus using an electric vibrator is difficult to use for administering a liquid medicine and simply vibrates the feet of a user, and accordingly both foot massage apparatus can not have a massage effect by pressure such as a momentary impact or continuous impact. DISCLOSURE OF THE INVENTION Accordingly, it is an object of the present invention to provide a foot massage apparatus which is capable of improving a massage effect by impacting continuously or intermittently on the sole as well as the top side of the feet of a user by using water pressure, and selecting a liquid medicine massage or a cold-hot water massage as occasion demands. It is another object of the present invention to provide a foot massage apparatus which is capable of adjusting a combining angle of an upper casing coupled to a lower casing, and performing acupressure with water currents while also performing acupressure with an acupressure roller. It is still another object of the present invention to provide a foot massage apparatus which is capable of jetting an aromatic agent during a massage by including an aromatic agent jetting means, and of drying the wet feet of the user efficiently after a massage by hot air from a hot-air drying means. It is yet another object of the present invention to provide a foot massage apparatus which is capable of performing various massages such as an acupressure massage with an acupressure roller, a cold-hot water massage, a salt massage, a liquid medicine massage, etc. efficiently by means of a heater installed between a detachable water vessel and a pump and an input tube installed at a certain side of a main body in order to inject ice, salt and various liquid medicines into the detachable water vessel installed at the lower casing of the main body. It is further another object of the present invention to provide a foot massage apparatus which is capable of improving an acupressure effect by performing acupressure with a plurality of acupressure rods intermittently by using air pressure. In order to achieve the above-mentioned objects of the present invention, there is provided a foot massage apparatus including an upper casing, a lower casing and an openable casing cover. Accordingly it is possible to clean every nook and corner of the foot massage apparatus by opening the casing cover. A fixation contact rubber for fixing an ankle of a user is installed at the casing cover in order to dam up jets of water. The fixation contact rubber has a flexibility and elasticity, is soft to the touch by utilizing a contact portion and a pleat portion in design and is suitable for all sizes of ankle. A limit switch operated by a movable contact rubber is installed at the casing cover so as to prevent the water from leaking outwardly due to a wrong operation. In addition, because a pair of rubber lids shutting a pair of foot insertion holes of the casing cover is included in the foot massage apparatus, it is possible to shut the pair of foot insertion holes in cleaning of the foot massage apparatus using jet-water, and it is also possible to protect the foot massage apparatus from dust penetrating into the main body by putting a pair of rubber lids on the foot massage apparatus when the foot massage apparatus is in safekeeping or not in use for a long time. The foot massage apparatus includes jet heads each having a jet nozzle and separately installed at the front side, the rear side and the lower side of a main body. The jet nozzle of each jet head is formed not as a shower type but with three holes in order to jet water very strongly. Water currents jetted from the three jet nozzles jetting water are shut and opened by turns in accordance with the rotation of an impeller installed inside the jet head in an intermittent effect, whereby the intermitted water currents are jetted to the feet, and accordingly a massage effect can be maximized by beating and stimulating the feet. The jet heads are installed at about 40 spots in order to jet the strongest water current with the same water pressure. Three nozzles are formed at each jet head, and the total of 120 water currents massage the feet efficiently by beating the whole feet strongly and intermittently. Accordingly the massage effect can be maximized in a very short time. A plurality of cylinder-shaped recesses are formed within a pair of virtual foot installation regions at the bottom surface of the upper casing. An intermittent jet head is separately installed at each recess, and a pressure water supply pipe is connected to a pressure water chamber. The intermittent jet head installed at each recess is placed along acupressure points of the feet (i.e., a passage for circulating energy and blood up and down and branches divided from the passage in a network, in order to circulate energy and blood to every nook and corner of a body) as in oriental medicine, and accordingly an acupressure massage effect can be added. An intermittent acupressure means including an acupressure rod can be installed as occasion demands in order to perform acupressure with the acupressure rod being protruded intermittently. When a plurality of acupressure rods are protruded intermittently by air pressure, the acupressure effect can be doubled. A footstool fabricated with a metal net for putting the feet thereon comfortably is installed at a position at a distance of 100 ~ 150mm from the jet nozzle of the front jet means where the effect of the water pressure is maximized, and an acupressure roller is installed at the center of the footstool. An input tube is installed at the side of the main body, and ice, salt, various medicines, etc. injected into the input tube dissolve in the water of the detachable water vessel installed at the lower casing of the main body. Accordingly, acupressure with the acupressure roller, various massages such as a cool/hot water massage, a salt massage, a medicine massage, etc. can be performed. Because the inner bottom surface of the upper casing of the main body slopes upward, the strongly jetted water flows into the detachable water vessel at the lower casing of the main body through a drain outlet installed at the rear of the bottom surface, and then flows into the detachable water vessel after being filtered through a mesh screen combined with the drain outlet. Herein, because the mesh screen is removable, it is easy to clean the mesh screen. As for the mesh screen, a carbon filter may be used to clean the used water. In addition, because the detachable water vessel can be easily separated from the main body, it is easy to clean and there is no need to move the main body near to a water supplier. And as there are graduations on the water vessel, water can be easily and accurately filled into the detachable water vessel. An ultraviolet lamp is installed at the upper portion of the detachable water vessel in order to sterilize the water inside the water vessel. Accordingly it is possible to perform a sanitary massage. When the user inserts the detachable water vessel into the lower portion of the main body, a discharge pipe of the detachable water vessel is connected with a water supply pipe of a pump, and a valve installed at the discharge pipe of the detachable water vessel is opened. When the user pulls the water vessel outwardly, the valve is shut. Because a mesh screen is connected with the discharge pipe of the detachable water vessel, it is possible to perform a massage with clean water. When a double filtering arrangement is adopted by installing a mesh screen between the discharge pipe of the detachable water vessel and the water supply pipe of the pump, it is possible to perform a massage with cleaner water by which can be prevented more surely impurities from penetrating into a pump motor. A heater is installed at the center portion of the pump in order to heat the water to a certain degree. The water temperature is adjusted by a precise temperature sensor sensing the water temperature and an electronic circuit. The heating means can be used safely by increasing a life span and decreasing a hazard such as an electric leakage, etc. by embedding the heater into a circular pipe (i.e., a cylinderical pipe is made of aluminum), and because the inner circumferential portion of the circular pipe which forms a passage for the water is formed with a concave-convex shape, the heating efficiency can be maximized. The water supplied from the detachable water vessel flows into a pump after passing through the heating means, is directly delivered into the jet heads placed at the bottom surface, the front surface and the rear surface of the main body by a pumping force of the pump, flows into an inlet hole formed so as to be symmetric with respect to the peripheral wall of the cylinder unit and rotates an impeller combined with each jet head. As the impeller of each jet head rotates by the pressure of the water, a shutter plate of the impeller periodically shuts/opens a nozzle hole formed in the nozzle cover of each jet head. Accordingly, the feet can be massaged by the water jetted intermittently and strongly. The water does not flow through small pipes individually but flows a minimum quantity through a pressure water chamber with only passage of water divided into a bottom jet means, a front jet means and a rear jet means, whereby a water current is jetted stronger by increasing a pressure of the water and maintains the same water pressure in each nozzle by directly connecting each nozzle to the minimum quantity of the pressure water chambers. Because the rear portion of the lower casing is hinge-combined with the upper casing, the front portion of the upper casing can be lifted by being separated from the lower casing, whereby the user can use the foot massage apparatus at the easiest angle by adjusting the angle of the upper casing at a certain degree for the convenience of the user. An aromatic agent jet means is combined with the casing cover. Accordingly it is possible to jet an aromatic agent inside the main body during the massage. A hot air drying means is installed inside the main body. Accordingly, it is possible to dry the feet easily after the massage. And, in order to perform the above-mentioned functions, an operation panel controlling various functions and including switches such as a power switch, a water pressure switch adjusting a water pressure as a high pressure or a low pressure, a temperature adjusting switch adjusting a water temperature as a low, a medium or a high temperature, an ultraviolet sterilization lamp switch turning on/off an ultraviolet sterilization lamp and a dryer switch operating a dryer, etc. is installed at the front upper surface of the main body in the easiest position to operate the foot massage apparatus for a user, and all the above-mentioned functions are controlled by an electronic circuit.

The operation of the foot massage apparatus in accordance with the present invention will now be described. In order to use the foot massage apparatus in accordance with the present invention, water is filled into the detachable water vessel 130 to a certain level, and the detachable water vessel 130 is inserted into the lower casing 20 through the opening 21 formed in the lower casing 20. The discharge pipe 131 of the detachable water vessel 130 is inserted into the water supply pipe 210 of the pump 200 and the switch valve 140 connected with the discharge pipe 131 is opened by being pushed by the protrusion pin 211 of the water supply pipe 210. In addition, the angle of the upper casing 10 can be adjusted in accordance with a user's desire with the angle adjusting means 40 installed at the middle portion of the main body. After that, the user opens the pair of rubber lids 17, inserts the feet through the pair of foot insertion holes 13 formed at the casing cover 18, puts the feet on the footstool 70 installed inside the upper casing 10, and slide- moves the movable contact rubber 82 of each foot insertion hole sealing means 80 with the handle 82f until each movable contact rubber 82 contacts to the foot. Accordingly, the limit switch is turned on by the movable contact rubber 82, and thus the foot massage apparatus operates. After that, the water from the detachable water vessel 130 is filtered by passing through the mesh screen 136 of the discharge pipe 131 of the detachable water vessel 130 by a pumping force of the pump 200, is sterilized by the ultraviolet sterilization lamp 225, flows into the water supply pipe 210 of the pump 200, is pumped into the pressure water chamber 12 of the lower jet means 100 installed inside the upper casing 10 and the jet pipes 111 , 121 of the front and rear jet means 110, 120 through the pressurized water supply pipe 220, and is jetted from the intermittent jet heads 150 of the bottom, front and rear jet means 100, 110, 120 with a strong jet pressure in accordance with the operation of the power switch 91 , the timer switch 92, the water pressure switch 93 and the ultraviolet sterilization lamp switch 95 of the operation panel 90. When the water flows through the inlet hole 158 formed at the circumferences of the cylinder unit 151 , because the shutter plate 154 periodically opens and shuts the nozzles 156 of the nozzle cover 157 while 5 the impeller 155 installed at the cylinder unit 151 rotates by the influx of the water, the intermittent jet head 150 jets water currents intermittently, and accordingly a massage effect can be maximized by stimulating generally and evenly the soles of the feet, the top sides of the feet and the ankles, etc. with the water currents jetted with the strong jet pressure. o And, the user can add salt or various medicines through the input tube 170 as occasion demands in use of the foot massage apparatus, can use hot water by heating the water to a certain temperature, can use cool water by inserting ice into the input tube 170, and accordingly it is possible to perform efficiently various massages such as a cool or hot water massage, a salt 5 massage, a liquid medicine massage, etc., and have an acupressure effect by using the acupressure roller 60. As described above, the water currents jetted from the intermittent jet heads 150 of the bottom, front and rear jet means 100, 110, 120 generally and evenly beat the feet, then the water drip down the lower portion of the o upper casing 10, gather together at the drain-outlet 14 along the inner bottom surface of the upper casing 10, is filtered by the mesh screen 15, flows into the detachable water vessel 130, and circulates and is jetted repeatedly. And, when pressurized air is provided from the intermittent pressure means 240 to the plurality of intermittent acupressure means 230 combined with the bottom and front jet means 110, 120 while a massage is performed by jetting water through the intermittent jet heads 150 of the bottom, front and rear jet means 100, 110, 120, the multistage telescoping tube 232 and the acupressure rod 233 combined with the cylinder open portion of the pressure passage 231 which are pressed as depicted in Figure 13b are extended out by the elasticity of the elasticity restoring means 236 as depicted in Figure 13a. As the acupressure rod 233 is repeatedly pressed and extended in accordance with the periodic opening and shutting of the pressure air by the intermittent valve 241 of the intermittent pressure means 240, the rubber cap 234 installed at the upper end of each acupressure rod 233 lightly beats the soles and tops of the feet, and accordingly, the user can have the acupressure effect by the plurality of acupressure rods 233. When the feet massage ends in accordance with the above-mentioned operation, the operation of the pump 200 and the ultraviolet sterilization lamp 225, etc. is stopped, and the hot air is generated by operating the blower 191 and the ceramic heater 192 of the hot-air drying means 190 in order to dry the wet feet, and thereafter the user pulls out the feet after the feet are dried and cuts off the power by pressing the power switch 91. In order to clean the inside of the main body after using the foot massage apparatus, the user fills clean water into the detachable water vessel 130, covers the pair of foot insertion holes 13 with the pair of rubber lids 17 and operates the foot massage apparatus. In addition, since the main body is divided into the upper casing 10 and the lower casing 20, and the casing cover 18 combined with the upper casing 10 is removable, the user can clean every nook and corner of the main body by opening the casing cover 18. INDUSTRIAL APPLICABILITY As described above, a foot massage apparatus in accordance with the present invention is sanitary because a user can clean every nook and corner of the foot massage apparatus. In addition, the foot massage apparatus can perfectly shut off strongly jetted water by installing a contact rubber for fixing an ankle, because the contact rubber has a characteristic of rubber and adopts a slide method or a fastening method fixing a foot according to the size of the ankle by including a contact portion and a pleated portion, the contact rubber is smooth to the touch and is adjustable for all different sizes of ankle, because a limit switch operating by a movable contact rubber is installed to a upper casing, the foot massage apparatus can prevent the water from leaking outwardly due to a wrong operation. In addition, because a pair of rubber lids for covering a pair of foot insertion holes of the casing cover is combined, in cleaning of the foot massage apparatus with clean water there is no need to worry about leakage of the water and it is possible to prevent impurities from entering into the main body in long safekeeping by covering with the rubber covers. The foot massage apparatus includes a jet head having a jet nozzle separately installed at the front surface, the rear surface and the bottom surface. The nozzle of each jet head is formed as not a shower type but with three holes in order to jet the water very strongly, the water currents jetted from the three jet nozzles are shut and opened by turns in accordance with a rotation of an impeller installed inside the jet head in an intermittent effect. The intermitted water currents are jetted to the feet, and accordingly a massage effect can be maximized by beating and stimulating the feet. The jet head is installed at 40 portions in order to jet the strongest water currents with the same water pressure, and three nozzle holes are formed at each jet head, so a total of 120 water currents massage the feet by beating the whole feet strongly and intermittently, and accordingly the massage effect can be maximized in a very short time. The water supplied from the detachable water vessel and passed through a heating unit flows into a pump, the pumped water directly flows into the jet heads placed evenly at the bottom surface, the front surface and the rear surface of the main body. The impeller of each jet head rotates by a jet pressure of the water. The water is jetted intermittently and massages by beating the whole feet while a shutter plate of the impeller periodically opens and shuts the nozzle hole formed at the nozzle cover. Herein, because the water is jetted through a minimum volume of a pressure water chamber formed with only a passage of the water through a bottom jet means, a front jet means and a rear jet means in order to have a more strong and a constant pressure, the water current is stronger as a pressure of the water increases, and the same water current can be maintained by directly connecting each nozzle to the same minimum volume of the pressure water chamber. A footstool is installed at a portion where the water pressure is maximized from the nozzles, and an acupessure roller is installed at the center portion of the footstool. And, because an input tube is installed at a certain side of the main body, ice, salt, and various medicines filled in the input tube dissolve in water contained in the water vessel installed at the lower casing of the main body, and accordingly it is possible to perform acupressure with the acupressure roller and perform various massagess such as a cool-hot water massage, a salt massage, a medicine massage, etc. When the jet heads are placed along acupressure points of feet (i.e., a passage for circulating energy and blood up and down and branches divided from the passage in a network in order to circulate energy and blood every nook and corner) as in oriental medicine, an acupressure massage effect is added. Because an intermittent acupressure means having a plurality of acupressure rods is separately installed at the bottom, the front and the rear surface jet means, it is possible to perform acupressure by using each acupressure rod intermittently, and accordingly the acupresure effect is increased double. Because the inner bottom surface of the main body slopes upward, the strongly jetted water flows into the detachable water vessel at the lower casing of the main body through a drain-outlet installed at the rear of the bottom surface, and flows into the detachable water vessel after being filtered through a mesh screen combined with the drain-outlet. Herein, because the mesh screen is removable, it is easy to clean. In addition, because the detachable water vessel can be easily separated from the main body, it is easy to clean and there is no need to move the main body near to a water supply, and because there are graduations on the detachable water vessel, the water can be easily and accurately filled into the detachable water vessel. An ultraviolet lamp is installed at the upper portion of the detachable water vessel in order to sterilize the water inside the detachable water vessel, and accordingly it is possible to perform a sanitary massage. When the user inserts the detachable water vessel inside the lower portion of the main body, when a discharge pipe of the detachable water vessel is connected with a water supply pipe of a pump, a valve installed at the discharge pipe of the detachable water vessel is opened, When the user pulls the detachable water vessel outwardly, the valve is shut, and accordingly it is easy to handle. Because the mesh screen is combined with the discharge pipe of the detachable water vessel, it is possible to perform a massage with clean water. When a double filtering method is adopted such as installing a mesh screen also between the discharge pipe of the detachable water vessel and the water supply pipe of the pump, it is possible to perform a massage with cleaner water and can prevent more surely impurities from penetrating into a pump motor. A heater of a heating means is installed at the center portion of the pump in order to heat the water to a certain degree. The heating means can be used safely by increasing a life span and decreasing a hazard such as an electric leakage, etc. due to the water by building the heater inside a circular pipe (i.e., a cylindrical pipe made of aluminum), and because the inner circumference portion of the circular pipe which is a passage for the water is formed with an uneven shape, the heating efficiency can be maximized. Because the rear portion of the lower casing is hinge-combined with the upper casing, the front portion of the upper casing can be lifted by being separated from the lower casing, so the user can use the foot massage apparatus at the easiest angle for the convenience of the user by adjusting the angle of the upper casing at a certain degree. An aromatic agent jet means is combined with the casing cover, accordingly it is possible to jet an aromatic agent inside the main body during a massage. A hot-air drying means is installed inside the main body. Accordingly it is possible to dry the wet feet easily after the massage.
