Description

  The present invention relates to a bathtub unit including a bath in which hot water for bathing is stored and a water receiving unit that receives low-temperature liquid such as low-temperature water that is lower in temperature than the hot water in the bath. The present invention relates to a head water shield used for (covering).

  For example, as a hot spring facility, a bath where a person takes a bath and a discharge port such as a faucet adjacent to the bath and separate from the hot water stored in the bath are cooler than the hot water in the bath The bathtub unit including a water receiving portion from which water is released and receives low-temperature water has a configuration that allows low-temperature water to be received by the head, such as the face, while the entire body is immersed in the bathtub. . Receiving cold water on the face is considered to have an effect of encouraging bathing for a long time because there is a temperature difference from the hot water in the bath.

  However, since the low-temperature water outlet is above the water receiving part, when the body is placed in the bathtub and the head is placed on the water receiving part and the low-temperature water is received by the head, a part of the low-temperature water is received. Is reflected on the head including the face, and cannot be received in the water receiving portion, and it is inevitable that low-temperature water enters the bathtub. The flow of low-temperature water into the bathtub will lower the temperature of the hot water in the bathtub, and dirt on the head will also enter the bathtub. Absent.

  However, since there are not many such hot spring facilities equipped with facilities for discharging low-temperature water in addition to bathing baths, the reflected water generated when bathing low-temperature water on the head is kept in the water receiving section. No dedicated equipment is currently available or developed.

  In addition to the bathtub, there is a bathtub unit equipped with a hair tub for washing the head adjacent to the bathtub (see Patent Documents 1 and 2). Although it is similar to a bathtub unit with a water part, this unit does not include a dedicated part for preventing the washing water whose head has been washed in the hair tub from flowing into the bathtub or scattering.

  In Patent Document 1, since a dedicated drain hole is not formed in the hair tub, the washing water accumulated in the hair tub must be scraped off. In Patent Document 2, a drainage hole (drainage pipe) for discharging washing water is connected to the hair washing tub separately from the bathtub. There is no function to prevent scattering.

  Several hat-shaped equipments (shampoo hats) for blocking washing water that allow the bather to wash the hair while bathing in the bathtub have been proposed (see Patent Documents 3 to 5).

JP 2001-299615 A (Claim 1, paragraphs 0006 to 0016, FIGS. 1 to 7) JP 2007-222415 A (Claim 1, paragraphs 0012 to 0022, FIGS. 1, 3, and 4) JP 2000-354511 A (Claim 1, paragraphs 0005 to 0019, FIGS. 1 to 3) JP 2001-353019 A (Claim 1, paragraphs 0006 to 0011, FIGS. 1 to 6) JP 2012-81226 A (Claim 1, paragraphs 0008, 0009, FIG. 1, FIG. 2)

  However, since the shampoo hats in Patent Documents 3 to 5 are in the form of covering around the head, as described above, the shampoo hat is not a form suitable for bathing the entire head above the neck including the face. Even if these hats can be applied around the neck, the water received on the upper surface of the shampoo hat is in a state of running down from the upper surface. The function of guiding the cleaning water to the drain hole connected (communication) to the cleaning tank is not performed.

  From the above background, when the present invention is applied to a bathtub unit similar to the bathtub of Patent Document 2 having the above-described water receiving portion (hair washing tub), for example, a cold liquid such as cold water is bathed on the head, It proposes a head water shield for improving the certainty of draining water into the discharge hole of the water receiving part without flowing into the bathtub.

According to the first aspect of the present invention, there is provided a headwater impervious device, wherein a hot tub for bathing is stored, a tub adjacent to the tub, and discharged separately from the hot water in the tub. A water receiving portion that receives a cryogenic liquid having a temperature lower than that of the hot water in the entry bathtub, and the water receiving portion is used in a bathtub unit having a discharge hole for discharging the cryogenic liquid independently of the bath.
Wearing around the neck of the bather, having an area larger than the head , having an insertion hole through which the head is inserted and arranged around the neck, maintaining the form when receiving the cryogenic liquid An inner peripheral portion around the insertion hole of the main body portion is extendable in the circumferential direction, and at least part of the outer peripheral portion of the main body portion in the water receiving portion. It is a constituent requirement to have a fixing portion that is inserted and prevented from coming off in the water receiving portion.

  The bathtub unit is basically composed of a bathtub and a water receiving part, and a discharge hole for discharging the low temperature liquid is formed or connected to the inner peripheral surface of the water receiving part. “Draining the cryogenic liquid independently of the bathtub” in claim 1 means that a drain hole for cryogenic liquid different from the drain hole formed in the bathtub is formed (connected) in the water receiving portion, This means that the cryogenic liquid received at the water receiving section is drained directly from the water receiving section, and when there is no human head in the water receiving section, the cryogenic liquid crosses the hot water in the bathtub in the water receiving section. It is discharged from the water receiving part. The position and shape of the discharge hole of the water receiving portion are not limited. As described above, the low-temperature liquid is discharged from the discharge port such as a faucet, and the low-temperature water lower in temperature than the hot water in the bathtub. A cleaning liquid or a cosmetic liquid that is applied (released) directly to the entire head is included.

  The water receiving part 3 has a shape that allows the bather to put his head on when taking a bath in the bath 2, and the bather places his head on the water receiving part 3 as shown in FIG. In the state, it is possible to take a posture in which the body below the neck is immersed in the bathtub 2. The water shield 6 is used in a state of being worn around the neck of the bather, and is fixed when the bather puts his head on the water receiving part 3 and takes a body soaking in the bath 2. The part 65 is housed in the water receiving part 3 including the discharge hole 4 and is in a stable state, and the water receiving part 3 and the bathtub 2 are partitioned in the used state. Since the water shield 6 has the ability to maintain its form when it receives a low temperature liquid, it is prevented from slipping out in the water receiving part 3 in a part of the fixing part 65 of the outer peripheral part 64, so that the low temperature liquid discharge side The state which partitions the discharge hole 4 and the bathtub 2 of the water-receiving part 3 is maintained, receiving low-temperature liquid on the surface.

  The “main body portion of the water shield” in claim 1 mainly refers to the entire water shield 6, but refers to a portion excluding the inner peripheral portion 63 and the outer peripheral portion 64 around the insertion hole 62, In some cases, the peripheral portion 63 and the outer peripheral portion 64 are included. “Surface” means that the main body 61 has a planar or plate-like shape as a whole, and may be planar or curved. In the case of a curved surface, in order to fulfill the function of blocking the low temperature liquid, it is appropriate that the discharge port 5 or the like side (discharge side) is concave.

  “The main body has a larger area than the head” means that the main body of the head in a direction perpendicular to the plane including the insertion hole 62 of the main body 61 with the water shield 6 attached to the head. It means that the main body 61 has a larger area than the projected area on the part 61. As shown in FIG. 1- (a), when the water shield 6 is attached to the head, the area on the face side of the main body portion 61 enters the bathtub 2 of the cryogenic liquid discharged from the discharge port 5 or the like. In order to influence the effect of preventing the inflow, the area on the face side with respect to the center of the insertion hole 62 is larger than the area on the back of the head as shown in FIG. Is more effective.

  Since the main body 61 has a larger area than the head, as shown in FIG. 1- (a), the inner periphery 63 is attached around the neck of the bather, and the bather puts his head on the water receiving part 3 When the body is immersed in the bathtub 2, the water receiving part 3 (the discharge hole 4) is partitioned from the bathtub 2, and the low temperature liquid discharged from the discharge port 5 and the like is separated from the water receiving part 3 and the bathtub. It works to dam at the boundary of 2 and prevents the low temperature liquid from flowing into the bath tub 2, including the amount reflected and scattered by the bather's head. The water shield 6 is used to drain the cryogenic liquid to the discharge hole 4 of the water receiving section 3 without bathing the cryogenic liquid on the head when bathing into the bathtub and letting the cryogenic liquid flow out to the bathtub 2. The inner peripheral portion 63 and the outer peripheral portion 64 of the main body portion 61 indicate edge portions that are continuous in the circumferential direction with a certain width at the inner peripheral portion and the outer peripheral portion of the main body portion 61, respectively. It is formed into an arbitrary shape such as a polygonal shape or an elliptical shape.

  By blocking the low temperature liquid discharged from the discharge port 5 or the like at the boundary between the water receiving portion 3 and the bathtub 2 and preventing the low temperature liquid from flowing into the bathtub 2 or scattering. The bath 2 when the temperature of the hot water in the bath 2 is lowered due to the low-temperature liquid flowing into the bath 2 and the dirt of the head is diffused into the bath 2 or the low-temperature liquid is a cleaning liquid or the like. It becomes possible to avoid mixing with the warm water inside.

  The inner peripheral part 63 which is located around the neck of the bather in the state of use of the water shield 6 and circulates around the insertion hole 62 extends when the head passes, and contracts after passing through the neck. For example, a synthetic resin such as polyurethane, a synthetic fiber such as polyester, and a synthetic / natural rubber material having an appropriate stretchability. In addition, the body 61 of the water shield 6 needs to be elastically deformed when the bather is worn on the neck and detached, and when the fixing unit 65 is inserted into the discharge hole 4 or the like, and at least a low-temperature liquid is applied. Since the receiving side needs to have water repellency or water impermeability, it is made of a material such as a synthetic resin such as soft polyvinyl chloride having flexibility and water impermeability.

  Wearing the water shield 6 around the neck is, for example, making a radial cut between the inner periphery 63 and the outer periphery 64, and the water shield 6 itself sandwiches the cut in the circumferential direction. Or it is also possible by making it the form which can be separated in the thickness direction, but in that case, there is a high possibility that the low temperature liquid leaks from the cut during use and enters the bathtub 2. On the other hand, in the present invention, the inner peripheral portion 63 around the insertion hole 62 is continuous in the circumferential direction and is closed, so that leakage of the low-temperature liquid into the bathtub 2 when making a break is avoided.

  “The main body portion can maintain its form when it receives a low-temperature liquid” means that the main body portion 61 has an out-of-plane rigidity that can maintain the state where the main body portion 61 stands up from the neck as shown in FIG. In addition, it means that the planar shape can be maintained without bending deformation even with the pressure of the low temperature liquid. The fact that the main body portion 61 has an out-of-plane rigidity that can resist water pressure specifically gives the main body portion 61 an out-of-plane rigidity that can withstand the pressure of the low-temperature liquid, or the main body portion 61 has an out-of-plane rigidity. The outer peripheral portion 64 is made of a material having a rigidity higher than that of the main body portion 61. When the material of the main body part 61 and the outer peripheral part 64 are different, or when the cross-sectional shapes of the main body part 61 and the outer peripheral part 64 are different (the main body part 61 and the outer peripheral part 64 are separate), the outer peripheral part 64 is connected to the main body part 61. Are integrated by bonding, welding, stitching or the like.

  As shown in FIG. 5A, the main body 61 itself has an out-of-plane rigidity because a detachable outer peripheral portion 64, which is a separate frame from the main body portion 61, is formed on the outer peripheral portion of the main body portion 61. When connected (adhered) and integrated, the main body 61 is tensioned in the in-plane direction, or the main body 61 is made hollow like a floating ring as shown in FIG. It is also possible to inject air into the main body 61 during use and expand it. The out-of-plane rigidity can be imparted to the outer peripheral portion 64 by leaving the outer peripheral portion 64 hollow as shown in FIG. 3C and injecting air into the outer peripheral portion 64 during use.

  As in the example shown in FIG. 5A, the outer peripheral portion 64 that is detachable from the main body 61 is a rod-like component that is connected to each other of a regular polygon by a pin so as to be foldable, for example, like a folding scale. When the rods located on both sides in the longitudinal direction of the rod-shaped part are connected to each other with pins while being connected to the outer peripheral portion of the body portion 61, the regular polygonal shape is maintained, and at the same time, The form is also maintained. In this case, the outer peripheral portion 64 is detachably connected (adhered) to the outer peripheral portion of the main body portion 61 by a hook-and-loop fastener 7 or the like.

  For example, as shown in FIGS. 1 and 2, the fixing unit 65 is inserted into the water receiving unit 3 and is prevented from coming off in the water receiving unit 3. To the inner peripheral surface of the drainage hole 4 (invention 2), or as shown in FIG. It becomes possible by inscribed such as engaging at two points (corner portions 66, 66) in the circumferential direction of the water shield 6. In addition, a suction cup or an adhesive sheet connected to the water shield 6 is attached to the inner peripheral surface of the water receiving part 3 or the drain hole 4 by suspending a weight inserted into the drain hole 4 from the fixing part 65. This can be achieved by temporarily bonding them.

  When the fixing unit 65 is inserted into the discharge hole 4 of the water receiving unit 3 and is prevented from coming off (Claim 2), the fixing unit 65 is connected to the water receiving unit 3 as shown in FIGS. When engaged in the circumferential direction and the thickness direction of the water shield 6 (outer peripheral part 64) in the state inserted into the drainage hole 4 entering from the inner peripheral surface, or when contacting on the peripheral surface The insertion state is maintained by generating a frictional force. As a result, in a state where the water shield 6 is mounted around the neck, the main body portion 61 comes out of the discharge hole 4 due to the water pressure and bather movement when receiving the low temperature liquid, or in the out-of-plane direction. Stability is secured against behavior such as movement, rotation around the insertion hole 62 (in-plane direction), and vibration.

  In the state shown in FIG. 3A, the fixing unit 65 is engaged in any direction of rotation in the circumferential direction of the water shield 6. The fixing unit 65 is fixed in the thickness direction of the water shield 6 even if it is not sandwiched in the discharge hole 4 in the thickness direction of the water shield 6 as shown in FIG. The surface on one side and the surface on the other side of the portion 65 are in contact with the inner peripheral surface facing the discharge hole 4, or the portion near the fixing portion 65 of the outer peripheral portion 64 is on the inner peripheral surface facing the discharge hole 4. Stable by touching. When the water shield 6 is viewed in the in-plane direction, the point (line) or the line (surface) on both sides in the thickness direction of the lower end of the fixing unit 65 is the inner periphery of the water receiving unit 3 or the discharge hole 4. If the surface is in the state of being engaged in the out-of-plane direction of the water shield 6, the water shield 6 will ensure stability against movement in the out-of-plane direction.

  3- (a) and 4- (b), the inner peripheral surface of the water receiving portion 3 has a funnel shape from the upper side to the drain hole 4, and the drain hole 4 When the shape is such that the cross-sectional area gradually decreases, for example, as shown in FIG. 3A, the fixing portion 65 simply has a shape along the inner peripheral surface of the drain hole 4, or FIG. 4- (a) and (b), the portions (corner portions 66, 66) on both sides in the length direction of the fixing portion 65 formed in a straight line form the inner peripheral surface of the water receiving portion 3 and the drain holes 4. By coming into contact with the inner peripheral surface, it is easy to stabilize against slipping when inserted into the water receiving part 3 or the discharge hole 4. Further, as shown in FIGS. 1B and 2, the flow force at the time of discharging the low temperature liquid is relaxed on the inner peripheral surface of the water receiving portion 3, on a part of the discharge hole 4 or in the vicinity of the discharge hole 4. In the case where the buffer groove 3a is formed (to suppress the bounce at the time of reflection) or for other purposes, the fixing portion 65 is placed in the buffer groove 3a and stabilized as shown in FIG. You can also.

  However, due to insufficient rigidity of the fixing unit 65 in a state where the fixing unit 65 is inserted into the inner peripheral surface of the water receiving unit 3 or the inner peripheral surface of the drainage hole 4, If sufficient stability against slipping out in the drain hole 4 cannot be obtained, the fixing unit 65 is given rigidity sufficient to be stable against slipping out in the inner peripheral surface of the water receiving part 3 or in the drain hole 4. (Claim 3). The fixing portion 65 may be a part of the outer peripheral portion 64 as shown in FIG. 3, or may be the entire outer peripheral portion 64 as shown in FIG. In the latter case, any side (section) of the polygonal outer peripheral portion 64 is selectively used as the fixing portion 65. Since the fixing portion 65 is at least a part of the outer peripheral portion 64, when the out-of-plane rigidity is given to the outer peripheral portion 64 as described above, it is not necessary to give the fixing portion 65 special rigidity. When the main body portion 61 has out-of-plane rigidity and the outer peripheral portion 64 does not have out-of-plane rigidity, the fixing portion 65 is given rigidity.

  The fact that the rigidity of the fixing portion 65 is higher than the rigidity of the main body portion 61 is different from that of the main body portion 61 in the outer peripheral portion 64 as the fixing portion 65 as shown in FIG. This is possible by using a hard material and integrating the outer peripheral portion 64 to the main body portion 61 by bonding, welding, stitching, or the like, or by detachably bonding (connecting). Alternatively, as in the case of increasing the rigidity of the outer peripheral portion 64, it is also possible to leave only the fixing portion 65 hollow and inject air into the fixing portion 65 during use. The outer peripheral part 64 shown to Fig.5- (a) has shown the example in the case of being connected to the outer peripheral part of the main-body part 61 so that attachment or detachment is possible.

  Since the fixing unit 65 has rigidity sufficient to be stable against slipping out in the inner peripheral surface of the water receiving unit 3 or the drain hole 4, the fixing unit 65 is disposed in the inner peripheral surface of the water receiving unit 3 or discharged. Since it becomes difficult to be deformed in the hole 4, for example, when the body of the bather changes its posture, when the force in the in-plane direction and the out-of-plane direction of the main body 61 acts on the fixing unit 65, the water receiving unit 3 or the inner peripheral surface of the drainage hole 4 can be easily maintained, and the stability against slipping out of the water receiving portion 3 and the drainage hole 4 is improved.

  In particular, when the fixing portions 65 are formed in a straight line as shown in FIG. 5 or the like, corner portions 66, 66 are formed on both sides in the circumferential direction (length direction) of the fixing portion 65 (Claim 4). As shown in FIG. 4, at two points on both sides in the circumferential direction of the fixing portion 65, the inner peripheral surface of the water receiving portion 3, the inner peripheral surface of the discharge hole 4, or the inner peripheral surface of the buffer groove 3a is contacted. Therefore, it is possible to obtain a state in which it is difficult to rotate in the in-plane direction in a state where the main body portion 61 itself is mounted around the neck, and stability in a mounted state on the neck is improved. The “corner portion 66” referred to here is a corner that is formed on both sides of one side of the fixing portion 65 and is convex toward the outer peripheral side of the main body 61 when the fixing portion 65 is one side of the polygon. Since it refers to a corner and refers to a portion that directly contacts the inner peripheral surface of the water receiving portion 3 or the like, it is not necessarily a portion having a clear angle.

  In this case, when the fixing portion 65 is in contact with the inner peripheral surface of the water receiving portion 3 at two points (corner portions 66 and 66) on both sides in the circumferential direction as shown in FIG. Since the fixing portion 65 can receive reaction force from the inner peripheral surface and the like of the water receiving portion 3 at two points when trying to rotate around the center of the insertion hole 62, the water shield 6 rotates in the circumferential direction ( It becomes difficult to swing. When the corner portion 66 of the fixing portion 65 is in contact with the inner peripheral surface of the water receiving portion 3 or the discharge hole 4, the corner portion 66 is the water receiving portion 3 or the drain hole 4 unless there is a particular vertical movement. When rotating in any direction around the center, the inner peripheral surface can be engaged and cannot be pulled out, so that it is difficult to rotate.

  Further, when the outline of the main body 61 is formed in a polygonal shape and the fixing unit 65 is a portion corresponding to one of the sides of the outer peripheral part 64 of the main body 61 (Claim 5), the outer periphery of the main body 61 Since the fixing portions 65 corresponding to the number of sides are formed in the portion 64, for example, by changing the lengths of the sides of the polygon as shown in FIGS. ) In the water receiving part 3 or the discharge hole 4 according to the width of the inner peripheral surface of the water receiving part 3 in the horizontal direction of the water shield 6 or the depth of the discharge hole 4 as shown in FIG. It is possible to give freedom to select the fixing unit 65 for stabilization. In this case, the fixing portion 65 is a portion corresponding to any one side of the outer peripheral portion 64 formed continuously in the circumferential direction along the polygonal side. “A portion corresponding to any side of the outer peripheral portion 64” means that the outer peripheral portion 64 includes a polygonal side that is the outline of the main body portion 61, and is a portion having a certain width in the radial direction. The part including any side of the polygonal shape is the fixing unit 65.

  When the outline of the main body 61 is an unequal side polygonal shape as shown in FIGS. 5B and 5C, the outer periphery 64 of the main body 61 has a plurality of sides with different lengths. Since the fixing portions 65 having a plurality of lengths are formed, for example, when the water receiving portion 3 or the discharge hole 4 has a funnel shape, as shown in FIG. The fixing portion 65 is brought into contact with the inner peripheral surface of the water receiving portion 3 or the discharge hole 4 at two points (corner portion 66) corresponding to the difference in the distance between the inner peripheral surfaces of the water receiving portion 3 or the discharge hole 4. Is possible. When the water receiving part 3 or the discharge hole 4 is funnel-shaped, the distance between the inner peripheral surfaces in the horizontal direction of the water receiving part 3 or the discharge hole 4 changes according to the depth from the bottom surface of the water receiving part 3. Since the lengths of the plurality of fixing portions 65 are different, fixing to the water receiving portion 3 or the discharge hole 4 according to the depth of the water receiving portion 3 or the discharge hole 4 or according to the shape of the discharge hole 4. It is possible to select (change) the fixing unit 65 to be made. When the fixing portions 65 having a plurality of lengths are formed, and when the buffer groove 3a is formed in the water receiving portion 3, it is possible to cope with a difference in the length of the buffer groove 3a.

  In the case where rigidity is imparted by injecting air into the outer peripheral portion 64, there is a possibility that the corner portion 66 of the fixing portion 65 does not appear clearly due to the injection of air, but the fixing portion is injectable by injecting air into the outer peripheral portion 64. Since 65 expands, it is possible to insert the fixing unit 65 in a contracted state between the inner peripheral surfaces facing the horizontal direction of the water receiving unit 3 or between the opposing end surfaces of the buffer groove 3a. As a result, the fixing portion 65 can be brought into close contact with the inner peripheral surface of the water receiving portion 3 or the like by the restoring force to expand at the time of contraction, so that the stability against coming out in the inserted state can be obtained.

  Further, when the outer shape of the main body 61 is a polygonal shape, the water shield 6 is in the water receiving portion 3 or the center of the drainage hole 4 is eccentric with respect to the center of the main body 61 (Claim 6). It is possible to cope with a difference in the height of the user or the height of the neck, that is, a difference in the distance from the position of the fixing part 65 in the water receiving part 3 or the discharge hole 4 to the neck. For example, when the outline of the main body 61 is a line-symmetrical hexagon as shown in FIG. 5B, three sides having different lengths are formed, and the insertion hole 3a is formed from these three sides. Since the distance to the center of the head is different, this different distance is the distance from the fixing unit 65 to the center of the neck. As shown in FIG. 5- (c), when the outline of the main body 61 is axisymmetric with respect to a straight line passing through the midpoint of any side of the hexagon and the center of the insertion hole 62, the lengths are different. Four sides are formed.

  When the body part of the water shield has an area larger than the head and has the ability to maintain the form when it receives low-temperature liquid, it is attached to the head of the bather who took a bath in the bath In order to divide the water receiving part and the bath tub and to dampen the low temperature liquid released from the discharge port etc. at the boundary between the water receiving part and the bath tub, It can prevent flowing into the bathtub. As a result, it is possible to avoid a decrease in the temperature of hot water in the bathtub and diffusion of dirt on the head into the bathtub due to the low temperature liquid flowing into the bathtub.

  FIG. 1- (a) shows a bath 2 in which hot water for bathing is stored, and a low-temperature liquid adjacent to the bath 2 and discharged separately from the hot water in the bath 2 and lower in temperature than the hot water in the bath 2 The water-impervious tool 6 used with the bathtub unit 1 provided with the water-receiving part 3 which receives is shown when the bather's neck is mounted | worn around the neck of a bather. The water shield 6 is used for the purpose of draining the low temperature liquid to the discharge hole 4 of the water receiving section 3 without bathing the low temperature liquid into the bathtub 2 when the bather bathes in the bathtub 2. . The low-temperature liquid is discharged from the discharge port 5 or the like installed above the water receiver 3, or is discharged from the dedicated container or the like in the water receiver 3 or on the water receiver 3. FIG. 2 shows a situation when the relation between the water shielding tool 6 and the water receiving part 3 in the state of FIG. The low-temperature liquid is mainly discharged from the discharge port 5 or the like, and may be low-temperature water having the same component as hot water, cleaning liquid discharged from a container, or cosmetic liquid.

  The water shield 6 has an area larger than the bather's head, has an insertion hole 62 through which the head is inserted and arranged around the neck, and has a form when receiving a low temperature liquid from the discharge port 5 or the like. It consists of a planar main body 61 that can be maintained. The inner peripheral portion 63 around the insertion hole 62 of the main body 61 is formed of a material that can expand and contract in the circumferential direction so that the head can be inserted when being attached to the neck and detached from the neck. At least a part of the outer peripheral portion 64 in the circumferential direction has a fixing portion 65 that is inserted into the water receiving portion 3 and is prevented from coming off within the water receiving portion 3.

  The main body 61 of the water shield 6 should have at least an area larger than the area when the head is projected in a direction perpendicular to the surface of the main body 61, but receives the low-temperature liquid reflected on the face and enters the bathtub 2. As shown in FIG. 3- (a), it is more effective to have a larger area on the face side with respect to the center of the insertion hole 62 as shown in FIG. However, the larger the area of the main body 61, the easier it is to bend and deform due to the water pressure of the low temperature liquid, so the area of the main body 61 is determined by adjusting the prevention of low temperature liquid scattering and bending rigidity.

  A specific example of the water shield 6 shown in FIGS. 1 and 2 is shown in FIG. In FIG. 3A, the main body 61 has a circular shape, and the fixing portion 65 is inserted into the discharge hole 4 of the water receiving portion 3 so as to be prevented from coming off into the discharge hole 4. An example of the water shield 6 having a form in which the inner peripheral portion 63 has a hollow cross-sectional shape and ensures rigidity by injecting air into each of the inner peripheral portions 63 is shown. FIG. 3- (c) shows a cross section taken along line yy of (a). In this example, in order to increase the effect of preventing the low temperature liquid from flowing into the bathtub 2 as described above, the center of the insertion hole 62 is positioned lower than the center of the main body 61 and the face side with respect to the center of the insertion hole 62 is placed. Is larger than the area on the occipital side.

  In the example shown in FIG. 3A, the outer peripheral portion 64 is the entrance of the drainage hole 4 and the inner peripheral surface of the water receiving portion 3 as shown in FIG. A part of the outer peripheral portion 64 that is expanded by injecting air while the fixing portion 65 can be engaged in the in-plane direction and the out-of-plane direction of the main body portion 61 in the discharge hole 4. By closely contacting the inner peripheral surface of the portion that transitions from the water receiving portion 3 to the discharge hole 4, the water shield 6 is maintained in the inserted state into the water receiving portion 3 and is stable against coming out.

  In FIG. 1-(b), a buffer groove 3 a is formed on the inner peripheral surface of the water receiving unit 3 to suppress the splash at the time of reflection of the low temperature liquid that is discharged from the discharge port 5 and reflected on the inner peripheral surface of the water receiving unit 3. The longitudinal section of the water receiving part 3 when formed is shown. FIG. 2 shows a plan view of the water receiving section 3 in FIG. 6 shows a state in which the fixing portion 65 of the water shield 6 shown in FIGS. 5A to 5C is inserted into the buffer groove 3a and fixed when the buffer groove 3a is formed in the water receiving portion 3. FIG. Show.

  FIG. 4- (a) receives the corner portions 66, 66 on both sides in the circumferential direction (length direction) of the fixing portion 65 of the water shield 6 formed in the polygonal shape shown in FIGS. 5- (a) to (c). (B) shows the inner peripheral surface of the water receiving unit 3 according to the length of the fixing unit 65, in which the fixing unit 65 is prevented from coming off in the water receiving unit 3 by contacting the inner peripheral surface of the water unit 3. The corners 66 and 66 on both sides of the fixing unit 65 are brought into contact with any position in the section from the drainage hole 4 to the drainage hole 4 to prevent it from coming off in the water receiving unit 3.

  In the example shown in FIG. 4, the corners 66, 66 on both sides of the fixing unit 65 face the horizontal direction in the inner peripheral surface of the water receiving unit 3 and in the surface of the water shield 6, and are inclined with respect to the horizontal. , The fixing unit 65 is engaged with the inner circumferential surface of the water receiving unit 3 in the length direction (horizontal direction) of the fixing unit 65. When the corner portion 66 of the fixing portion 65 comes into contact with the surface inclined with respect to the horizontal, it is in a state of being restrained against movement in the horizontal direction, and at the same time, the water shield 6 around one of the corner portions 66. The other corner portion 66 is unlikely to lift even when trying to rotate, and the water shield 6 is less likely to rotate.

  FIG. 5- (a) shows a case where the water shield 6 is completed by detachably connecting an outer peripheral portion 64 separate from the main body portion 61 to the outer peripheral portion of the main body portion 61 formed in a regular hexagonal shape. An example is shown. In this case, the outer peripheral portion 64 is formed of a material having sufficient out-of-plane rigidity that can give rigidity to the main body portion 61 such as hard plastic, and is bonded to the outer peripheral portion of the main body portion 61 by, for example, a hook-and-loop fastener 7 or the like. The The outer peripheral portion 64 has a shape in which the outer peripheral portion of the main body portion 61 is sandwiched from both sides in the thickness direction, and the hook-and-loop fastener 7 is provided in advance on both the thickness direction both sides of the outer peripheral portion of the main body portion 61 and the inner peripheral surface in the thickness direction of the outer peripheral portion 64. Be joined.

  The outer peripheral portion 64 in this case is combined with the main body portion 61 when the main body portion 61 does not have sufficient rigidity to maintain a planar shape. In the drawing, the rod-shaped parts connected to each side of the hexagon are connected while being wound around the outer peripheral portion of the main body portion 61 by folding the outer peripheral portion 64 having a bent shape connected to each other by pins or the like at both ends in the length direction. The form of the outer peripheral part 64 itself and the connection method of the outer peripheral part 64 to the main body part 61 are not questioned at all. The bar-shaped part not connected to the main body 61 in the state shown in FIG. 5A is coupled to the connected bar-shaped part when the shaft of the pin of the connected bar-shaped part enters when connecting to the main body 61. .

  FIGS. 5B and 5C show an example in which the main body 61 of the water shield 6 is formed in a hexagonal shape with unequal sides. (B) is a case where the main body portion 61 is formed in a line-symmetric shape with respect to a straight line passing through any vertex of the hexagon and the center of the insertion hole 62, and the outer peripheral portion 64 has three sides having different lengths. (C) is a case where the main body portion 61 is formed in a line-symmetric shape with respect to a straight line passing through the midpoint of any side of the hexagon and the center of the insertion hole 62, and the outer peripheral portion 64 has four different lengths. It is.

  In the example shown in FIGS. 5B and 5C, the distance from the center of the insertion hole 62 to the center of each side (fixing portion 65) is different for each side having a different length. From the fixing unit 65, the position of the bather's neck (height from the inner peripheral surface of the water receiving unit 3), the inner peripheral surface of the water receiving unit 3 in which the fixing unit 65 is accommodated, or the depth of the drain hole 4. There is an advantage that the fixing portion 65 to be fixed to the inner peripheral surface of the water receiving portion 3 or the drain hole 4 can be selected according to the difference.

  FIG. 6 shows the fixing portion 65 of any one of the water shields 6 shown in FIGS. 5A to 5C inserted into the buffer groove 3a formed on the inner peripheral surface of the water receiving portion 3 and fixed. The situation when Whether one of the plurality of fixing portions 65 of the water shield 6 shown in FIGS. 5A to 5C having the fixing portions 65 having a plurality of lengths is used as the fixing portion 65 is the length of the buffer groove 3a. It is selected according to the size.

  7 divides the main body 61 of the water shield 6 into a radial direction (radial direction) into a region near the inner peripheral portion 63 (inner peripheral region 61a) and a region closer to the outer peripheral portion 64 (outer peripheral region 61b). The inner peripheral region 61a near the peripheral portion 63 is formed in a solid thin plate shape, the outer peripheral region 61b close to the outer peripheral portion 64 is formed in a hollow cross-sectional shape, and air is injected into the inside, thereby maintaining the form. The example at the time of forming the water shield 6 in the form which ensures (rigidity) is shown.

  In this example, the main body 61 is radially divided into a thin inner peripheral region 61a and a hollow outer peripheral region 61b, and an inner peripheral region 61a in which air is not injected is formed in a region near the inner peripheral portion 63 around the insertion hole 62. Thus, there is an advantage that the inner peripheral portion 63 is easily expanded and contracted when the neck is passed through the insertion hole 62.

  For example, when the entire main body 61 on the outer peripheral side of the inner peripheral portion 63 has a hollow cross section and expands by injecting air, the main body 61 expands in the state of injecting air into the main body 61 and the inner periphery It is assumed that the inner peripheral portion 63 is less likely to expand and contract when the portion 63 is pressed and the neck is passed through the insertion hole 62. On the other hand, in FIG. 7, a thin inner peripheral region 61a as a buffer region is formed near the inner peripheral portion 63 of the main body 61, and the inner peripheral region 61a is solid, so that a hollow cross section into which air is injected is formed. Therefore, even when air is injected into the outer peripheral region 61b and inflated, the outer peripheral region 61b is less likely to press the inner peripheral portion 63 from the outer peripheral side, and the neck is inserted into the insertion hole 62. It is avoided that the inner peripheral part 63 becomes difficult to expand and contract when passing.

  In FIG. 7, the outer peripheral portion of the outer peripheral region 61b having a hollow cross section in the hexagonal main body 61 is made thinner than the outer peripheral region 61b, and a thin outer peripheral portion 64 is formed in the outer peripheral portion of the outer peripheral region 61b. ing. Here, the outer peripheral portion of the hollow body section 61 (outer peripheral area 61b) is made thinner than the outer peripheral area 61b, thereby forming a hollow outer peripheral section 64 that is thinner than the outer peripheral area 61b around the main body section 61. It has become a shape.

  In this example, since the outer peripheral portion 64 has a hexagonal shape, a section on any side of the outer peripheral portion 64 that hits the hexagonal side serves as the fixing portion 65, the inner peripheral surface of the water receiving portion 3, the drain hole 4, or the buffer. It is inserted into the groove 3a and fixed. In this case, the outer peripheral portion 64 is hollow, but is thin, so that the discharge hole 4 or the like into which the fixing portion 65 is inserted has a narrow shape.

  In the production example shown in FIG. 7, clear corners 66 are not formed on both sides in the length direction of the fixing unit 65 that hits the hexagonal side, but the hollow cross section is continuous with the main body 61 (outer peripheral region 61 b). Due to the expansion due to the injection of air into the interior, the drain hole 4, the buffer groove 3 a, and the boundary between the inner peripheral surface of the water receiving portion 3 and the drain hole 4 can be brought into close contact with each other. Secured.
