Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower limb bath apparatus that is useful not only for elderly people and disabled persons with disabilities in the lower limbs, but also for general people, and in particular, a shower nozzle apparatus that includes a plurality of shower nozzles that spray relatively hot liquid such as hot water onto the legs About.

JP 2004-298558 A

  However, when hot water is sprayed from the spray nozzles of the sole shower nozzle, the upper shower nozzle, and the calf shower nozzle, the hot water is applied to areas other than the injection target areas of the instep, sole, and calf. Is injected, the hot water injected from one shower nozzle and the hot water injected from another shower nozzle may interfere with each other when the axis of injection extending from the injection port intersects. . And it is assumed that the kinetic energy of warm water falls by interference of this warm water, and sufficient collision impact cannot be given to a jetting target site | part. In this regard, the lower limb bath device described in Patent Document 1 does not particularly show the prevention of the problem that the hot water jetted from one shower nozzle and the hot water jetted from another shower nozzle interfere with each other.

  Also, a relatively large impact (striking force) is required on the sole of the foot, and a relatively small impact is required on the shin facing the foot. The increase / decrease of this impact can be achieved by adjusting the injection amount per area of the injection target area. Although it is conceivable to perform, the configuration for adjusting the injection amount is not particularly shown in the lower limb bath device described in Patent Document 1.

  Accordingly, the present invention provides a lower limb bath device that is improved so as to prevent mutual interference when liquid is ejected from a plurality of shower nozzles, and in which the ejection area is varied depending on the area to be ejected. With the goal.

  The lower limb bath device according to the present invention is a lower limb bath device for bathing the lower limbs of a human body by taking a shower on the foot, a bathtub unit in which the foot is put, and a support body that supports the put foot. A shower nozzle device capable of spraying liquid from a plurality of directions toward the foot supported by the support, and the shower nozzle of the shower nozzle device is provided on the back side of the foot supported by the support. A foot shower nozzle that sprays the liquid toward the back, a foot shower nozzle that sprays the liquid toward the back side of the foot supported by the support, and the foot supported by the support. A shin shower nozzle for spraying the liquid toward the shin side, and a shower nozzle for foot shin that sprays the liquid toward the shin side of the foot supported by the support, The shape of the distribution area of the liquid from the shower nozzle for the sole and the shower nozzle for the instep is a perfect circle shape or a shape similar to this, and the liquid from the shower nozzle for the shin for the foot and the shower nozzle for the foot shin The shape of the injection distribution area is an ellipse or a shape close to this (Claim 1). Here, a sole shower nozzle, an instep shower nozzle, an inflatable shin shower nozzle, and an inflatable shin shower nozzle are provided for each of, for example, a right foot and a left foot.

  It is preferable that the liquid is a liquid having a relatively high temperature and a temperature that does not cause a problem to the human body (Claim 2). Here, for example, warm water having a temperature that does not cause burns on the human skin is used as the liquid having a relatively high temperature and no problem with the human body.

  In the lower limb bathing apparatus according to the present invention, the range of the spray distribution area of the liquid sprayed from each shower nozzle is the spray for the shin of the human body that is the target for the shin shower nozzle and the foot shin shower nozzle. It is adjusted so that it does not exceed the range seen from the mouth side, and the shower nozzle for soles and the shower nozzle for soles does not exceed the range seen from the injection port side for the instep and sole of the human body. It is also characterized by being adjusted (claim 3).

  In this way, by setting the range of the spray distribution area of the liquid ejected from each shower nozzle to be equal to or less than the range of each ejection target part, the liquid ejected from the shower nozzle is ejected wastefully other than the ejection target part. This can prevent the liquid ejected from one shower nozzle and the liquid ejected from another shower nozzle from interfering with each other. For this reason, the fall of the kinetic energy of the liquid injected from each shower nozzle can be prevented.

  Furthermore, in the lower limb bath device according to the present invention, the dimension from the ejection port of each shower nozzle to the site to be ejected is set according to the use of each shower nozzle (claim 4). As a result, in the shower nozzle for the sole, the size range from the injection port to the sole is made the smallest compared to the case of the other shower nozzle, so that the range of the spray distribution area sprayed from the other shower nozzle is relatively set. By making it narrow, it becomes possible to increase the amount of liquid ejected per predetermined area (liquid striking force), and thus it is possible to obtain a high massage effect on the sole. In addition, in the shower shin for the shin for the foot, the dimensional value from the spray port to the sole is maximized as compared to the other shower nozzles, so that the liquid ejection amount per predetermined area (liquid striking force) Therefore, the liquid can be sprayed evenly on the shin facing away so as to give a soft touch with a low impact, and the user feels uncomfortable such as painful spraying. It becomes possible to prevent giving.

  The lower limb bath device according to the present invention includes liquid supply means for supplying liquid to each shower nozzle of the shower nozzle device, and the liquid supply means includes a drain discharge mechanism. It is possible to discharge a liquid having a temperature other than that having no problem. Thereby, liquids other than the liquid having a relatively high temperature and no problem with the human body can be discharged out of the lower limb bath device from the drain discharge mechanism.

A specific configuration of each shower nozzle of the lower limb bath device according to the present invention is as follows: the foot shower nozzle, the foot shower nozzle, the foot shin shower nozzle, and the foot shin shower nozzle are adapters. And the nozzle body of the shower nozzle for the sole is relatively larger in diameter than the shower nozzle for the instep, and the nozzle body of the shower nozzle for the foot calf is with diameter of the injection port is larger relatively than the injection port of the shower nozzle the foot toward shin, the foot shin shower nozzle及beauty before Kiashi calf shower nozzle nozzle body, the nozzle A slit that opens toward the front end side of the main body is formed, and an injection port that opens toward the front end side of the nozzle main body is formed in the slit. The mouth is formed so that the inner diameter dimension along the longitudinal direction of the slit is longer than the inner diameter dimension along the short direction of the slit, and the nozzle body of the sole shower nozzle and the foot shower nozzle Is smaller as the shape of the portion in the vicinity of the opening of the ejection port advances in the direction in which the liquid is ejected (claim 1 ).

  As described above, according to the present invention, by setting the range of the spray distribution area of the liquid ejected from each shower nozzle to be equal to or less than the range of each ejection target part, the liquid ejected from the shower nozzle is ejected. It is possible to prevent the liquid ejected from one shower nozzle and the liquid ejected from another shower nozzle from interfering with each other. Therefore, it is possible to prevent a decrease in kinetic energy of the liquid ejected from each shower nozzle.

  In particular, according to the fourth aspect of the present invention, in the shower nozzle for the sole, the dimensional value from the injection port to the sole is made the smallest as compared with the case of the other shower nozzle, thereby injecting from the other shower nozzle. By making the range of the spray distribution area to be relatively narrow, it is possible to increase the amount of liquid sprayed per predetermined area (liquid striking force), and thus to obtain a high massage effect on the sole Is possible. In addition, in the shower shin for the shin for the foot, the dimensional value from the spray port to the sole is maximized as compared to the other shower nozzles, so that the liquid ejection amount per predetermined area (liquid striking force) Therefore, the liquid can be sprayed evenly on the shin facing away so as to give a soft touch with a low impact, and the user feels uncomfortable such as painful spraying. It becomes possible to prevent giving.

  In particular, according to the invention described in claim 2 and claim 5, the liquid other than the liquid having a relatively high temperature and no problem with the human body is discharged from the drainage mechanism out of the lower limb bath device, By reliably eliminating the possibility of being ejected from the shower nozzle, it is possible to avoid a dangerous state and an unpleasant state for the human body.

Further, what is indicated by reference numeral 33 is a pressure reducer disposed between the mixer 23 and the pressure pump 24.

  A procedure for using the lower limb bath apparatus constituted by the bathtub unit 1 and the hot water supply unit 20 will be described below.

  First, as shown by the imaginary line in FIG. 2, after the lid 3 is rotated upward to be in an open state, the user (bathtaker) borrows the help of himself or a caregiver and is shown in FIG. The foot is put into the bathtub unit 1 through the opening 6 while sitting on the chair. In this case, it is necessary to put the foot into the bathtub unit 1 until the footpad hits the support body 13 in the bathtub unit 1. When the operation of inserting the foot into the bathtub unit 1 is completed, the lid 3 is rotated downward and closed as shown by the solid line in FIG. This completes preparation for the user's lower limb bath.

Next, an ON / OFF switch (not shown) is pressed to turn on the hot water supply unit 20 to operate the water supply pumps 21 and 22 and the pressure pump 24. In this case, the electromagnetic valve 25 is closed, the electromagnetic valve 26 is opened, and a temperature adjustment operation is performed in advance to confirm that the temperature has reached an appropriate temperature, and then the electromagnetic valve 25 is opened and the electromagnetic valve 26 is closed. It is preferable to supply hot water to the shower nozzles 16 to 19 of the shower nozzle device 15 in a state.

  Here, the appropriate temperature of the hot water is a temperature that does not cause a problem in the human body, that is, a temperature that does not cause burns (including low-temperature burns) on the skin. A relatively low temperature that is between 43 ° C. and lower than this temperature should be avoided, and the hot water or cold water determined to be outside the range of 35 ° C. to 43 ° C. as described above is drained water. It is possible to avoid a dangerous state or an unpleasant state with respect to the human body by reliably eliminating the risk of being discharged from the shower nozzle.

  In this embodiment, the bathtub unit 1 and the hot water supply unit 20 are shown as separate and independent units. However, the present invention is not limited to this, and the units 1 and 20 are integrated into an integrated unit. The integrated unit is also included in the category of the bathtub unit 1 described in the claims.

By the way, each shower nozzle 16 thru | or 19 which comprises the shower nozzle apparatus 15 is comprised by the combination of the adapter part 35 and each nozzle main body 16a thru | or 19a , as FIG.4, FIG.6, FIG.9 and FIG.11 shows. The adapter part 35 is made common.

Among these, the adapter part 35 is a well-known thing, the holder 37 which the hole part 36 in which the base 40 mentioned below of the nozzle main bodies 16a thru | or 19a is accommodated is formed, and the engagement protruded from the side of the base 40 further An engagement hole 38 that can be engaged with the protrusion 42 is formed in a direction intersecting the hole 37 with respect to the holder 37.

  On the other hand, the nozzle body 16a and the nozzle body 17a of the shower nozzle for the sole function and function as a full cone spray nozzle (Full Cone Spray Nozzle) with respect to the shower nozzle 16 for the sole and the shower nozzle 17 for the instep. It is for giving, and is comprised from the substantially cylindrical base 40 and the front-end | tip part 41 provided in the front-end | tip of this base 40.

  The base 40 is formed with an engaging projection 42 that can be engaged with the engaging hole 38 of the adapter part 35, so that the adapter part 35 and the nozzle bodies 16a and 17a can be moved in the opposite direction or only one of them. By rotating, the engagement protrusions 42 of the nozzle bodies 16a and 17a enter the engagement holes 38 of the adapter part 35, and the adapter part 35 and the nozzle bodies 16a and 17a can be reliably fixed and connected.

  As shown in FIGS. 4, 5 (b), 6, and 7 (b), the distal end portion 41 extends from the base 40 side on the inner peripheral side of the substantially circular outer peripheral portion 43 cut out at two locations. A substantially conical (cone-shaped) ejection protrusion 44 is formed which squeezes as it advances to the opposite side of the base 40, and an ejection port 45 is opened at the tip thereof.

  As shown in FIGS. 5B and 7B, the shape of the injection port 45 is a circular shape or a shape approximating a circle, and accordingly, the injection port 45 is injected from the injection port 45. As shown in FIG. 8A, the hot water shower pattern has a circular shape centered on the X point indicating the position of the injection port 45, and the injection port 45 has a substantially conical injection projection 44. When the hot water injection distribution area is viewed from the radial direction of the injection port 45, it expands like a trapezoid with a hem extending.

  Furthermore, the inner diameter W1 of the nozzle 45 of the nozzle body 16a is larger than the inner diameter W2 of the nozzle 45 of the nozzle body 17a. The warm water particles ejected from the spray nozzle 45 of the foot shower nozzle 16 are, for example, about 500 μm, whereas the warm water particles ejected from the spray nozzle 45 of the foot shower nozzle 17 are, for example, approximately The foot shower nozzle 16 is larger than the foot shower nozzle 17.

  Also, the nozzle body 18a of the shin shower nozzle and the nozzle body 19a of the shin shower nozzle are one-touch nozzles (Standard Flat Spray Nozzle) with respect to the shin shower nozzle 18 and the shin shower nozzle 19. It is configured by a substantially cylindrical base 47 and a tip 48 provided at the tip of the base 47.

  The base 47 has substantially the same configuration as the base 40 of the foot shower nozzle 16 and the foot shower nozzle 17, and an engagement protrusion 49 that can be engaged with the engagement hole 38 of the adapter 35 is formed. By appropriately rotating the adapter part 35 and the like, the engaging projection 49 enters the engaging hole 38 of the adapter part 35, so that the adapter part 35 and the nozzle bodies 18a and 19a can be securely fixed and connected. It is possible.

  As shown in FIGS. 9, 10 (b), 11, and 12 (b), the distal end portion 48 extends from the base 47 side on the inner peripheral side of the substantially circular outer peripheral portion 50 cut out at two locations. A substantially columnar injection projection 51 extending on the opposite side to the base 47 is formed. The injection protrusion 51 has a notch 52 that extends linearly from end to end so as to pass through the center of the injection protrusion 51 and has a predetermined depth along the axial direction of the injection protrusion 51. Is formed. A substantially hemispherical pedestal 53 is formed on the bottom surface of the notch 52, and an injection port 54 is opened in the pedestal 53.

  Further, as shown in FIGS. 10B and 12B, the shape of the injection port 54 has an elliptical shape or a shape that approximates an ellipse such as a rugby ball. As shown in FIG. 13A, the shower pattern of the hot water sprayed from 54 has an elliptical shape centered on the X point indicating the position of the spray port 54, and the shape of the spray protrusion 53 is also present. When the injection distribution area of the hot water is viewed from the longitudinal direction in the radial direction of the injection port 54, the opening is widened like a substantially bowl shape with a large bottom and a shallow bottom.

  Further, the inner diameter dimension W3 in the short direction of the injection port 54 of the nozzle body 18a is smaller than the inner diameter dimension W4 in the short direction of the injection port 54 of the nozzle body 19a. The particle size of the hot water particles to be sprayed is, for example, about 200 to 300 μm for the warm water particles sprayed from the spray nozzle 54 of the shin shower nozzle 18, whereas the spray of the foot shin shower nozzle 19 is used. The fine particles of hot water sprayed from the mouth 54 are, for example, about 400 micrometers, and the shower nozzle 18 for the foot shin is smaller than the shower nozzle 19 for the foot shin.

  Thus, according to this lower limb bath device, the shower pattern of the hot water by the sole shower nozzle 16 and the instep shower nozzle 17 is circular as shown in FIG. It is possible to adjust so that hot water is not jetted over the soles and insteps that have a relatively large area when viewed from the top and within the range that almost satisfies the range, and beyond the outer edges of the soles and insteps It has become. Moreover, the shower pattern of warm water by the shower nozzle 18 for the shin for the shin and the shower nozzle 19 for the shin for the shin is elliptical as shown in FIG. 13A, and is relatively narrow and vertically long when viewed from the injection port 45 side. It is possible to adjust so that warm water is not jetted beyond the range of the part of the shin facing the foot or the shin of the foot. Therefore, in this lower limb bath device, it is avoided that the hot water sprayed from the spray ports 45 and 54 of the shower nozzles 16 to 19 interfere with each other.

  In addition, according to this lower limb bath device, the particle size of the fine particles of hot water sprayed from the spray port 45 of the foot shower nozzle 16 is applied to the sole of the foot where a thick and relatively strong impact is required. Because it is made the largest, it is possible to maximize the hitting force against the sole of the foot, and it can be set to give the necessary and sufficient hitting force as a massage on the sole of the foot, and it is injected thinly Hot water particles are not applied at all to the shin of the foot where the impact of warm water is easily transmitted to the bone, but instead of the hot water particles sprayed from the injection port 54 of the shower nozzle 18 for the shin. Since the particle diameter is made the smallest, it is possible to set so that the hitting force against the shin facing the foot is given in the smallest form. Furthermore, it is possible to set the particle size of the fine particles of hot water so as to give a suitable striking force to the instep and the shin of the foot according to conditions such as the thickness of the target part. Yes.

  And in this lower limb bath apparatus, the dimension from the object part of each shower nozzle 16 thru | or 19 can also be changed according to an object part. Thereby, in the shower nozzle 16 for soles, the dimension from the sole of the foot to the injection port 45 is made relatively short, and the hot water sprayed from the other shower nozzles 17 to 19 in the spray area of the warm water to the sole of the foot It is possible to increase the amount of hot water injection (impact or striking force) per predetermined area by making it narrower than the injection region, thereby giving a high massage effect. Moreover, in the shower nozzle 18 for foot shins, the dimension from the facing shin to the injection port 54 is made relatively long, so that the hot water spraying area toward the facing shin is made to the other shower nozzles 16, 17 and 19. Since it is larger than the hot water injection area injected from the area and the hot water injection amount per predetermined area is also reduced, it has an impact on the facing shin that has a height in the vertical direction compared to other parts. A liquid with a soft hitting force can be sprayed evenly.
