Description

[Technical Field]

[0001] The present invention relates to a bathroom system with a vibration unit. [Background technology]

[0002] Patent Document 1 discloses a bathtub acoustic device that allows bathers to experience music and vibrations. More specifically, Patent Document 1 discloses a water area sound generator that emits vibrations into the water area in the bathtub, and a spatial area sound generator that emits sound into a spatial area above the water area.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-128970 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the bathtub described in Patent Document 1 is a type of bathtub in which there is no wall above the rim formed above the tub. On the other hand, in a modular bath, a wall that defines part of the bathroom must be placed above the rim. Therefore, when installing a device (vibration unit) that allows users to experience vibrations in a modular bath, special care must be taken to prevent the vibrations from propagating to the wall or other part, causing unpleasant noise.

[0005] The present inventor has discovered a suitable installation method for a vibration unit that can effectively suppress the generation of unpleasant noise in a bathroom system in which a wall that partitions off part of the bathroom is placed above the rim portion.

[0006] The present invention (the first aspect) was devised based on the above findings. The first object of the present invention is to provide a bathroom system equipped with a vibration unit that can effectively suppress the generation of unpleasant noise.

[0007] Regarding another objective, the inventors discovered that by adjusting the height from the floor of the tub section to the vibration unit, it is possible to more effectively suppress noise caused by the shaking of the bathtub body toward the floor below, and to ensure that the strength of the vibrations imparted to the water by the vibration unit is sufficient.

[0008] The present invention (its second aspect) was devised based on the above findings. The second object of the present invention is to provide a bathroom system that can more effectively suppress noise caused by the shaking of the bathtub body toward the floor below, and can ensure that the strength of the vibrations imparted to the water by the vibration unit is sufficient.

[0009] Regarding yet another objective, the inventors discovered that the vibrating part of the vibration unit can be easily attached and detached to an opening provided in the wall of the tub portion on the side where the wall is placed, thereby improving the maintainability of the vibrating part of the vibration unit.

[0010] The present invention (the third aspect) was devised based on the above findings. A third object of the present invention is to provide a bathroom system equipped with a vibration unit that is easy to maintain. [Means for solving the problem]

[0011] A first aspect of the present invention is a bathroom system equipped with a bathroom, comprising: a bathtub having a tub portion and a rim portion formed above the tub portion; a vibration unit installed in the tub portion and imparting vibrations to the water stored in the tub portion; and a wall placed above the rim portion and partitioning a part of the bathroom, wherein the vibration unit has a vibrator that imparts vibrations to the water by vibrating relative to the water, and a support member fixed to the bathtub and supporting the vibrator so that it can vibrate, and the support member is fixed at a position offset from directly below the wall toward the inside of the tub portion.

[0012] According to this aspect, the support member of the vibration unit, which is the source of vibration for the bathtub, is fixed at a position offset from directly below the wall placed above the rim of the bathtub toward the inside of the tub.Therefore, when vibrations are generated by the vibrator vibrating, the vibrations transmitted to the bathtub are effectively prevented from being propagated to the wall placed above the rim, and ultimately, noise caused by the shaking of the wall can be effectively suppressed.

[0013] In the first aspect, it is preferable that the propagation direction of the vibrations imparted to the water by the vibrator forms an acute angle with respect to a direction perpendicular to the wall.

[0014] This more effectively prevents vibrations transmitted to the bathtub from being propagated to the wall placed above the rim, thereby more effectively suppressing the generation of noise caused by the shaking of the wall.

[0015] In the first aspect, it is preferable that the tub portion is provided with a hand rest portion, and the vibrator is located above the hand rest portion.

[0016] This suppresses the propagation of vibrations to the bathtub part below the hand rest area (particularly the bottom surface), thereby more effectively suppressing noise caused by the shaking of the bathtub body toward the floor below.

[0017] In this case, it is further preferable that the propagation direction of the vibrations imparted to the water by the vibrator forms an acute angle with respect to a direction perpendicular to the wall surface of the tub portion below the hand rest portion.

[0018] This more effectively suppresses the propagation of vibrations to the bathtub part below the hand rest area (especially the bottom surface), thereby more effectively suppressing noise caused by the shaking of the bathtub body toward the floor below.

[0019] On the other hand, in this case, the propagation direction of the vibrations imparted to the water by the vibrator is generally designed to coincide with the direction perpendicular to the wall surface of the tub portion above the hand rest portion.

[0020] This allows the vibration unit to be configured in a variety of conventionally known types.

[0021] Next, a second aspect of the present invention is a bathroom system equipped with a bathroom, comprising: a bathtub with a tub portion; a vibration unit installed in the tub portion and vibrating the water stored in the tub portion; and a washing area floor located near the tub portion, wherein the floor surface of the tub portion is positioned below the floor surface of the washing area floor, the upper edge of the tub portion is positioned above the floor surface of the washing area floor, the vibration unit is provided on the wall surface of the tub portion facing the washing area floor, the height from the floor surface of the tub portion to the vibration unit is higher than the height from the floor surface of the tub portion to the floor surface of the washing area floor, and the height from the vibration unit to the upper edge of the tub portion is also higher than the height from the floor surface of the tub portion to the floor surface of the washing area floor.

[0022] By making the height from the floor of the tub to the vibration unit higher than the height from the floor of the tub to the floor of the washing area, i.e., by placing the vibration unit at a position higher than the floor of the washing area, it is possible to more effectively suppress noise caused by the shaking of the bathtub body toward the floor below.Furthermore, by making the height from the vibration unit to the upper edge of the tub higher than the height from the floor of the tub to the floor of the washing area, it is possible to minimize the attenuation of the vibration from the vibration unit by the upper edge of the tub, and to ensure that the strength of the vibration imparted to the water by the vibration unit is sufficient.

[0023] In the second aspect, it is preferable that the washing area floor has an extending wall extending upward at the end on the tub portion side, and that the vibration unit is arranged at a position higher than the upper edge of the extending wall.

[0024] In order to prevent leakage of water that has flowed onto the washing area floor, an extension wall (not limited to a flat shape but including a curved shape, and called a "return" or the like) may be installed on the washing area floor. In such cases, the extension wall can act as an element to suppress vibration, but if the vibration unit is installed at a position higher than the upper edge of the extension wall, the strength of the vibration imparted to the water by the vibration unit can be made sufficient.

[0025] In addition, in the second aspect, it is preferable that the vibration unit is provided at a position lower than the standard height of water stored in the tub portion (which can be defined as, for example, 70% of the depth of the tub portion).

[0026] If the vibration unit is provided at a position lower than the standard height of the water stored in the tub portion, it is easy to ensure that the strength of the vibrations imparted to the water by the vibration unit is sufficient.

[0027] Next, a third aspect of the present invention is a bathroom system equipped with a bathroom, comprising: a bathtub having a tub portion and a rim portion formed above the tub portion; a vibration unit installed in the tub portion and vibrating the water stored in the tub portion; and a wall placed above the rim portion and partitioning a portion of the bathroom, wherein the vibration portion of the vibration unit is detachably installed in an opening provided in the wall surface of the tub portion on the side where the wall is placed.

[0028] According to this aspect, the vibration part of the vibration unit is detachably installed in the opening provided in the wall surface of the tub portion on the side where the wall is placed, and therefore the vibration part of the vibration unit is easy to maintain.

[0029] Preferably, the maintenance method comprises the steps of removing the vibration part of the vibration unit from the opening, performing maintenance work on the vibration part of the vibration unit removed from the opening, and reattaching the vibration part of the vibration unit to the opening.

[0030] Furthermore, in the third aspect, it is preferable that the vibration unit has a connection portion that is detachably connected to a power cord extending from the back of the wall of the tub portion, and that the connection portion, while connected to the power cord, can be pulled out from the opening to the inside of the tub portion together with a portion of the power cord.

[0031] This allows the connection part and part of the power cord to be pulled out from the opening to the inside of the tub part, and then the connection part can be removed from the power cord, making the vibration unit even easier to maintain.

[0032] In this case, the maintenance method preferably includes the steps of: pulling the connection part and a portion of the power cord from the opening toward the inside of the tub part in order to remove the vibration part of the vibration unit from the opening; removing the connection part from the power cord and removing the vibration part of the vibration unit from the opening; performing maintenance work on the vibration part of the vibration unit removed from the opening; reattaching the connection part to the power cord; and returning the connection part and the portion of the power cord to the back of the opening and reattaching the vibration part of the vibration unit to the opening.

[0033] Furthermore, in the third aspect, an attachment member is further provided that is installed on the opening or the vibration unit and can be attached and detached freely from the inner side of the tub portion, and when the attachment member is removed from the inner side of the tub portion, the vibration portion of the vibration unit is configured to be attachable and detachable to the opening, and when the attachment member is attached from the inner side of the tub portion, it is preferable that the vibration portion of the vibration unit is exposed when viewed from the inner side of the tub portion.

[0034] This prevents the mounting member from causing the vibrating part to come off the opening, while at the same time preventing the vibrations of the vibrating part from being hindered by the mounting member from being transmitted to the water inside the tub part, since the vibrating part is exposed when the mounting member is installed.

[0035] In this case, the maintenance method preferably includes the steps of removing the mounting member and removing the vibration part of the vibration unit from the opening, performing maintenance work on the vibration part of the vibration unit removed from the opening, and reattaching the vibration part of the vibration unit to the opening and reattaching the mounting member. [Effects of the Invention]

[0036] According to the first aspect of the present invention, the support member of the vibration unit, which is the source of vibration for the bathtub, is fixed at a position offset from directly below the wall placed above the rim of the bathtub to the inward side of the tub.Therefore, when vibrations are generated by the vibrator vibrating, the vibrations transmitted to the bathtub are effectively prevented from being propagated to the wall placed above the rim, and thus the generation of noise caused by the shaking of the wall can be effectively suppressed.

[0037] According to the second aspect of the present invention, by making the height from the floor surface of the tub section to the vibration unit higher than the height from the floor surface of the tub section to the floor surface of the washing area floor, noise generated in the direction of the floor below due to the shaking of the bathtub body can be more effectively suppressed, and further, by making the height from the vibration unit to the upper edge of the tub section higher than the height from the floor surface of the tub section to the floor surface of the washing area floor, the strength of the vibration imparted to the water by the vibration unit can be made sufficient.

[0038] According to the third aspect of the present invention, the vibration part of the vibration unit is detachably installed in the opening provided in the wall surface of the tub part on the side where the wall is placed, so that the vibration unit is easy to maintain.

[0040] (composition) An embodiment of the present invention will be described below with reference to the accompanying drawings. Fig. 1 is a schematic plan view of a bathroom system 100 according to an embodiment of the present invention, Fig. 2 is a schematic cross-sectional view of the bathroom system 100 of Fig. 1, Fig. 3 is a schematic cross-sectional view of a vibration unit 20 of Fig. 1, and Fig. 4 is a schematic exploded view of the vibration unit 20 of Fig. 1.

[0041] 1 and 2, the bathroom system 100 of this embodiment includes a bathroom and a bathtub 30 having a tub portion 32 and a rim portion 34 formed above the tub portion 32.

[0042] The bathtub 30 has a back wall surface to which the bather is expected to turn his / her back, a leg wall surface to which the bather is expected to turn his / her legs, a left wall surface to which the bather is expected to turn his / her left side, and a right wall surface to which the bather is expected to turn his / her right side.

[0043] The size of the bathtub 30 is, for example, a roughly rectangular (approximately oval) shape of 450 mm x 1,100 mm at the floor surface 31, a roughly rectangular (approximately oval) shape of 600 mm x 1,140 mm at the standard height when filling with hot or cold water (for example, 350 mm above the floor surface 31), and a roughly rectangular (approximately oval) shape of 650 mm x 1,350 mm at the upper opening surface (for example, 500 mm above the floor surface).

[0044] The back wall, leg wall, left wall, and right wall of the bathtub 30 all rise at an angle of 110° to the floor 31 (an angle inclined 20° from the vertical).

[0045] The tub section 32 of the bathroom system 100 of this embodiment is provided with four vibration units 20 that vibrate the water stored in the tub section 32. A wall 40 that separates part of the bathroom (on three sides) is placed above a rim section 34 that separates the three sides, and the remaining rim section 34 is located on the side of the washing area floor 50.

[0046] 3 and 4, each vibration unit 20 has a vibrator 7 that vibrates the water stored in the tub portion 32 by vibrating the water itself, and a fixed flange 9 that is a support member that is fixed to the bathtub 30 and supports the vibrator 7 so that it can vibrate. The fixed flange 9 is approximately cylindrical and is fixed to an opening provided in the wall surface of the tub portion 32 via a U-packing 14 and a fixing nut 15, and the vibrator 7 comes into contact with and moves away from the inner side surface (approximately circular) of the fixed flange 9 via a disk-shaped buffer material 8.

[0047] 1 and 2, the fixing flanges 9 of the three vibration units 20 on the three wall 40 sides (more precisely, the center points of the front faces of the disk-shaped buffer materials 8 fixed thereto) are fixed at positions offset (for example, positions offset by 20 mm or more) from directly below (the center of thickness of) the wall 40 toward the inside of the tub portion 32, at a height of 200 mm from the floor surface 31. In other words, the three vibration units 20 are provided at positions lower than the standard height of the water stored in the tub portion 32.

[0048] The fixed flange 9 (more precisely, the center point of the front face of the disk-shaped buffer material 8 fixed thereto) of one vibration unit 20 on the washing area floor 50 side is also fixed at a position symmetrical to the opposite fixed flange 9 (a position offset (for example, 20 mm or more) from directly below (the center of the thickness of) the imaginary wall 40 toward the inside of the tub portion 32, and at a height of 200 mm from the floor surface 31). In other words, the vibration unit 20 is also provided at a position lower than the standard height of the water stored in the tub portion 32.

[0049] Each fixed flange 9 is fixed so that its axis is perpendicular to the wall surface of the corresponding tub section 32. As a result, the vibration direction of each vibrator 7 (defined by the axis direction of the fixed flange 9), i.e., the propagation direction of the vibrations imparted to the water by that vibrator 7, is perpendicular to the wall surface of the tub section 32 on which that vibrator 7 is installed. As described above, each wall surface of the tub section 32 is inclined at 20° with respect to the vertical direction, and therefore the propagation direction of the vibrations imparted to the water by each vibrator 7 is inclined at 20° (forms an acute angle) with respect to the direction perpendicular to the wall 40.

[0050] In addition, the floor surface 31 of the tub portion 32 is positioned 80 mm lower than the floor surface of the washing area floor 50, while the upper edge of the tub portion 32 (the rim portion 34 in this embodiment) is naturally positioned higher than the floor surface of the washing area floor 50. As mentioned above, one vibration unit 20 is provided on the wall surface of the tub portion 32 facing the washing area floor 50, and the height Hb (see Figure 9) from the floor surface 31 of the tub portion 32 to the fixed flange 9 of the vibration unit 20 (more precisely, the center point of the front surface of the disc-shaped cushioning material 8 fixed to it) is higher than the height Hc (see Figure 9) from the floor surface 31 of the tub portion 32 to the floor surface of the washing area floor 50, and the height Ha (see Figure 9) from the fixed flange 9 of the vibration unit 20 (more precisely, the center point of the front surface of the disc-shaped cushioning material 8 fixed to it) to the upper edge of the tub portion 32 is also higher than the height Hc (see Figure 9) from the floor surface 31 of the tub portion 32 to the floor surface of the washing area floor 50.

[0051] Furthermore, referring to FIG. 1, reference numeral 60 denotes a heat insulating material, and reference numeral 70 denotes an insulating pan.

[0052] 3 and 4, the details of the vibration unit 20 will be further explained. A substantially cylindrical vibrator 7, which can vibrate under the action of electromagnetic force, is supported so as to be able to vibrate within a substantially cylindrical fixed flange 9. The vibrator 7 comes into contact with and separates from the inner side surface (substantially circular) of the fixed flange 9 via a disk-shaped cushioning material 8. In addition, cushioning material 8 is also placed below the vibrator 7 so that the vibrator 7 can vibrate smoothly within the fixed flange 9 (see FIG. 3).

[0053] A diaphragm 4 is adhered to the front side of the vibrator 7 with double-sided tape 6, and a vibration plate 3 is fixed to the diaphragm 4 with a washer-head pan head screw 5. These elements 3 to 6 vibrate in accordance with the vibration of the vibrator 7. With a fixing flange 9 fixed to the wall surface of the tub portion 32, the vibrator 7 and elements 3 to 6 (vibration portion) can be attached and detached to an opening provided in the wall surface of the tub portion 32.

[0054] A pair of upper and lower cylindrical pipes are provided on the inner side surface of the fixed flange 9 and extend further toward the inner side, and an elbow 11 is connected to each cylindrical pipe, and a braided hose 13 is further connected to each cylindrical pipe via a drainage joint 12. In Figures 3 and 4, the symbol 10 denotes a clamp.

[0055] A power cord 17 is routed through the upper braided hose 13, and the power cord 17 is connected to the vibrator 7 via a connection part 18 (connector, etc.). The connection part 18 is detachably connected to the power cord 17 extending from the back of the wall of the tub part 32, and while connected to the power cord 17, it can be pulled out from an opening in the wall of the tub part 32 to the inside of the tub part 32, along with a portion of the power cord 17. Meanwhile, the lower braided hose 13 is connected to a drain pipe.

[0056] In addition, the pressure plate 2 is screwed onto the fixed flange 9, and the mounting member 1 is fitted into the fixed flange 9 so as to conceal the pressure plate 2. The mounting member 1 and the pressure plate 2 can also be freely attached and detached to and from the opening provided in the wall surface of the tub portion 32 when the fixed flange 9 is fixed to the wall surface of the tub portion 32.

[0057] FIG. 5 is a schematic diagram illustrating the principle of vibration unit 20. In the format shown in FIG. 5, the magnitude of the vibration force is expressed as the Lorentz force (F=IBL). F is the magnitude of the vibration force, I is the value of the current flowing through the coil, B is the magnetic flux density generated at this time, and L is the length of the iron core. With the arrangement and configuration of vibration unit 20 as described above, diaphragm 3, which is part of the wall surface of bathtub 30, is directly vibrated, and vibrations are effectively imparted to the water contained in bathtub 30.

[0058] Fig. 6 is a diagram showing an image of the operation of vibrator 7. As shown in Fig. 6, a substantially cylindrical fixed flange 9 is fixed to bathtub 30, and vibrating vibrator 7 (and elements 3 to 6) inside fixed flange 9 causes vibrations to be imparted to the water stored in bathtub 30.

[0059] Fig. 7 is a diagram showing an example of the operation of another example of a vibrator. As shown in Fig. 7, when vibrators are directly attached to the walls of bathtub 30, the walls of bathtub 30 themselves are directly vibrated, which causes vibrations to be imparted to the water contained in bathtub 30.

[0060] (Action and effect) According to the bathroom system 100 of this embodiment as described above, the fixed flange 9 (support member) of the vibration unit 20, which is the vibration source for the bathtub 30, is fixed at a position offset toward the inside of the tub portion 32 from directly below the wall 40 placed above the rim portion 34 of the bathtub 30.Therefore, when vibrations are generated by the vibrator 7 vibrating, the vibrations transmitted to the bathtub 30 are effectively prevented from being propagated to the wall 40 placed above the rim portion 34, and thus the generation of noise caused by the shaking of the wall 40 can be effectively suppressed.

[0061] Furthermore, according to bathroom system 100 of this embodiment, the propagation direction of the vibrations imparted to the water by vibrator 7 forms an acute angle with the direction perpendicular to wall 40. This more effectively prevents vibrations transmitted to bathtub 30 from propagating to wall 40 placed above rim 34, thereby more effectively suppressing the generation of noise caused by the shaking of wall 40.

[0062] Furthermore, according to the bathroom system 100 of this embodiment, the height from the floor surface 31 of the tub portion 32 to the vibration unit 20 is higher than the height from the floor surface 31 of the tub portion 32 to the floor surface of the washing area floor 50, so noise generated in the direction of the floor below due to the shaking of the bathtub body can be more effectively suppressed, while the height from the vibration unit 20 to the upper edge of the tub portion 32 is also higher than the height from the floor surface 31 of the tub portion 32 to the floor surface of the washing area floor 50, so the strength of the vibration imparted to the water by the vibration unit 20 can be made sufficient.

[0063] Furthermore, according to the bathroom system 100 of this embodiment, since the vibration unit 20 is located at a position lower than the standard height of the water stored in the bucket portion 32, it is even easier to ensure that the vibration intensity imparted to the water by the vibration unit 20 is sufficient.

[0064] Furthermore, according to the bathroom system 100 of this embodiment, the vibration part (elements 3 to 7) of the vibration unit 20 is detachably installed in the opening provided in the wall surface of the tub section 32, which makes it easy to maintain the vibration part of the vibration unit.

[0065] The maintenance method can be carried out by the steps of removing the vibration part (elements 3 to 7) of the vibration unit 20 from the opening in the wall of the tub part 32, performing maintenance work on the vibration part (elements 3 to 7) removed from the opening, and reattaching the vibration part (elements 3 to 7) to the opening.

[0066] Furthermore, according to the bathroom system 100 of this embodiment, the connection part 18 and a portion of the power cord 17 can be pulled out from the opening toward the inside of the tub part 32, and then the connection part 18 can be removed from the power cord 17, making the vibration unit 20 even easier to maintain.

[0067] In this case, the maintenance method can be carried out by the steps of: pulling out connection part 18 and a portion of power cord 17 from the opening in the wall of tub part 32 toward the inside of tub part 32 in order to remove the vibration part (elements 3 to 7) of vibration unit 20 from the opening; removing connection part 18 from power cord 17 and removing the vibration part (elements 3 to 7) of vibration unit 20 from the opening; performing maintenance work on the vibration part (elements 3 to 7) of the vibration unit removed from the opening; reattaching connection part 18 to power cord 17; and returning connection part 18 and a portion of power cord 17 to the back of the opening and reattaching the vibration part (elements 3 to 7) of vibration unit 20 to the opening.

[0068] (Modification with "hand rest") FIG. 8 is a schematic cross-sectional view showing a modified example of a bathroom system having a "hand rest section."

[0069] As shown in FIG. 8, in the bathroom system of this modified example, hand rest section 33 is provided in tub section 32, and vibration unit 20 (vibrator 7) is located above hand rest section 33.

[0070] For example, the upper surface of the hand rest portion 33 is configured as a horizontal plane, and the height of the horizontal plane is 150 mm from the floor surface 31 of the tub portion 32.

[0071] 8, the wall surface of the tub section 32 below the horizontal plane of the hand rest section 33 is inclined by 5° relative to the vertical (θ2 = 95°), while the wall surface of the tub section 32 above the horizontal plane of the hand rest section 33 is inclined by 20° relative to the vertical (θ1 = 110°), and the fixing flange 9 of the vibration unit 20 (more precisely, the center point of the front face of the disk-shaped buffer material 8 fixed to it) is fixed at a position 50 mm above the horizontal plane of the hand rest section 33. (However, the vibration unit 20 is still installed at a position lower than the standard height of the water stored in the tub section 32.)

[0072] Other configurations of this modified example are substantially the same as those of the previously described embodiment explained using Figures 1 to 6. For example, the propagation direction of the vibrations imparted to the water stored in the tub portion 32 by the vibration unit 20 (vibrator 7) coincides with the direction perpendicular to the wall surface of the tub portion 32 above the hand rest portion 33. In this modified example, the same parts as those in the previously described embodiment are designated by the same reference numerals, and their description will be omitted.

[0073] According to this modified example, the propagation of vibrations to the bathtub part (particularly the bottom surface) below the hand rest portion 33 is suppressed, thereby more effectively suppressing noise caused by the shaking of the bathtub body toward the floor below.

[0074] Furthermore, according to this modification, the propagation direction of the vibrations imparted to the water by the vibration unit 20 (vibrator 7) forms an acute angle with the direction perpendicular to the wall surface of the tub portion 32 below the hand rest portion 33. This more effectively suppresses the propagation of vibrations to the bathtub portion (particularly the bottom surface) below the hand rest portion 33, and more effectively suppresses noise caused by shaking of the bathtub body toward the floor below.

[0075] (Modification with "return") FIG. 9 is a schematic cross-sectional view showing a modified example of a bathroom system having a "return."

[0076] As shown in Figure 9, in the bathroom system of this modified example, an extended wall 55 (not limited to a flat shape but also including a curved shape, and called a "return", etc.) is provided on the washing area floor 50 in order to prevent leakage of water that has flowed onto the washing area floor 50.

[0077] In such a case, the extending wall 55 can be an element that suppresses vibration, and in this modified example, the vibration unit 20 is located at a position higher than the upper edge of the extending wall 55, so the strength of the vibration imparted to the water by the vibration unit 20 can still be sufficient.

[0078] Other configurations of this modified example are substantially the same as those of the embodiment described above with reference to Figures 1 to 6. In this modified example, the same parts as those in the embodiment described above are denoted by the same reference numerals, and their description will be omitted.

[0079] (Attaching and detaching "mounting parts") FIG. 10 is a schematic diagram showing the attachment and detachment process of the "attachment member."

[0080] 10, a mounting member 1 is provided on vibration unit 20 at an opening in the wall of tub portion 32 so as to be detachable from the inside of tub portion 32. When mounting member 1 is removed from the inside of tub portion 32, the vibration section (elements 3 to 7) of vibration unit 20 is configured to be detachable from the opening, and when mounting member 1 is attached from the inside of tub portion 32, the vibration section (elements 3 to 7) of vibration unit 20 is exposed when viewed from the inside of tub portion 32.
