Description

Bathroom structure

Technical Field

The present invention relates to bathroom construction.

The present application claims priority based on japanese application No. 2021-155124, 9-24 of application date 2021, the contents of which are incorporated herein by reference.

Background

In recent years, various devices for nursing a person to be nursed such as a handicapped person and an elderly person are provided in houses, various facilities, and the like. As one of them, a bathroom configured to be capable of changing the position of a bathtub according to the physical characteristics of a care-receiver and the bathing operation is known.

For example, patent documents 1 and 2 disclose a bathroom unit including: a bath area table top; a bathtub carrying table board which falls one layer from the bath area table board; a movable bathtub capable of moving on a bathtub carrying table.

As in patent documents 1 and 2, when the bath tub placement table is lower than the bath area table, there is a risk that a portion of the bath tub placement table where the bath tub is not placed is directly exposed. Therefore, a side plate for making the height of the bath area table be identical is provided at the portion where the bathtub is not placed.

The side plate needs to be removed when the bathtub is moved, and needs to be reset at the exposed part of the bathtub carrying table surface after the bathtub is moved. The removal and repositioning of the side panels is required each time the bathtub is moved, which is a burden to the caregivers.

In addition, in the bathroom unit of patent document 1, since the difference in height between the bath area surface and the bathtub placement surface is large, there is also a problem in that the bath area surface and the bathtub surface have a large difference in height, and a care-giver easily loses his body balance when riding over the bathtub.

Accordingly, patent document 3 proposes a bathroom structure in which the height of a bathtub placement table is set to be equal to that of a bath area table, and the bathtub is placed in direct contact with the bathtub placement table.

According to the bathroom structure of patent document 3, the side plates do not need to be removed and replaced when the bathtub is moved, and since the difference in height between the bath area table and the bathtub table is small, the body balance is not easily lost when the caretaker straddles the bathtub.

On the other hand, in order to reduce the burden on caregivers, a bathtub provided with an automatic cleaning device has been proposed. For example, patent document 4 discloses a washing device in which a nozzle for injecting a detergent into a tub is mounted above the tub.

Patent document 5 discloses a washing device in which a nozzle for injecting washing water into a tub is installed at the center of the bottom of the tub. The manner of spraying the washing water from the bottom center of the tub to the periphery as in patent document 5 is suitable for washing the entire tub without omission.

Detailed Description

The bathtub structure of the present embodiment is provided with a bathtub unit and a waterproof tray provided with the bathtub unit. The tub unit is movable on the waterproof tray with a length direction of a tub in the tub unit as a moving direction.

The upper surface of the waterproof tray forms a bathtub tray table top, a bath area tray table top and a drainage longitudinal groove between the bathtub tray table top and the bath area tray table top which are respectively extended along the moving direction M.

Fig. 1 and 2 show an example of a bathtub unit 1 according to the present embodiment. Fig. 1 is a perspective view of the bathtub unit 1 as seen from the bath area side (bath area tray table side).

Fig. 2 is a sectional view II-II of fig. 1, which is a sectional view taken along the width direction N of the tub at the center of the moving direction M of the tub 10.

As shown in fig. 1, the bathtub unit 1 includes a bathtub 10, a nozzle 2 provided at the center of the bottom surface (bathtub bottom surface 20) of the bathtub 10, and a nozzle pipe 3 for supplying cleaning liquid to the nozzle 2. The nozzle pipe 3 is connected to the relay box 4. The relay box 4 is connected to a detergent supply pipe 6 for supplying detergent from a detergent container 5, and is connected to a flexible pipe 8 for supplying water from a tap water pipe 7.

The peripheral surface of the tub 10 is covered by the tub skirt 9.

The ratio (width (short diameter)/length (long diameter)) of the width (short diameter) to the length (long diameter) of the opening of the bathtub 10 is preferably 0.2/1.0 to 0.8/1.0, more preferably 0.3/1.0 to 0.7/1.0.

The nozzle pipe 3 is fixed to the tub bottom 20, the relay box 4 is fixed to the tub back 24, and the detergent container 5 is accommodated between the tub back 24 and the tub skirt 9. These transfer box 4, detergent container 5, nozzle pipe 3 and detergent supply pipe 6 move integrally with the tub 10 as the tub unit 1 moves.

Since the tap water pipe 7 is fixed to the wall surface of the bath room, the distance between the tap water pipe 7 and the relay box 4 varies with the movement of the bathtub unit 1. In order to cope with this distance change, the length of the flexible pipe 8 is set to a length having a margin.

The nozzle pipe 3 is connected to the nozzle 2 from the tub back 24 side via the lower side of the tub 10.

The nozzle pipe 3 is appropriately supplied with detergent or water via the relay box 4, and can discharge the detergent or water from the nozzle 2 into the tub 10.

As shown in fig. 3, the nozzle body 2a of the nozzle 2 protrudes to the lower side of the outer surface of the tub bottom 20 (tub bottom outer side 21). That is, there is a protruding portion protruding from the lower surface of the tub 10. The discharge port 2b of the nozzle 2 protrudes slightly upward from the inner side surface of the tub bottom 20 (the tub bottom inner side 22). The nozzle pipe 3 is disposed along the tub bottom outside 21 from the tub back 24 side (the bathroom wall side, the side opposite to the bath surface) and connected to the nozzle 2.

As shown in fig. 2, a slope G is provided on the tub bottom 20 so as to descend from the tub back 24 toward the tub front 23.

The gradient of the slope G is preferably 25/1000 to 30/1000. If the fractional gradient of the inclination G is equal to or greater than the lower limit value, the water in the tub 10 can be rapidly discharged from the tub drain 14. In addition, if the score gradient of the inclination G is equal to or less than the upper limit value, the safety of the care-receiver is improved.

As shown in fig. 1, 2 and 4, the bathtub drain plug 14 is provided so as to be long in the moving direction M in a position where the peripheral surface (bathtub front surface 23) of the bathtub 10 on the bathing area side intersects with the bathtub bottom surface 20 (position on the drainage longitudinal groove 50 side of the bathtub bottom surface 20). Since the inclination G exists in the tub bottom 20, this position becomes the lowest position of the tub bottom inner side 22.

The bathtub drain cock 14 is opened and closed by moving an elliptical cock cover 16 with respect to an elliptical drain outlet 15.

The angle θ of the axial direction of the drain outlet 15 with respect to the height direction T is preferably 55 to 65 °. By setting the angle θ to the lower limit value or more of the preferable range, the length of the drain outlet 15 protruding downward from the tub bottom outside 21 can be reduced. For example, if the angle θ is set to 62.5 °, the length of the drain outlet 15 protruding downward from the tub bottom outside 21 can also be suppressed to 10mm. Moreover, when the caregivers step over the tub front 23, the stepping on the tub drain plug 14 is easily avoided.

When the angle θ is equal to or smaller than the upper limit value of the preferable range, water is less likely to remain when water is drained from the bathtub 10.

The specific structure of the bathtub drain cock 14 is not limited, and for example, a drain cock device described in japanese patent application laid-open publication 2020-183648 can be used.

Next, the shape of the upper surface of the waterproof tray will be described with reference to fig. 5. The upper surfaces of the waterproof trays constitute a tub tray deck 30, a bath area tray deck 40, and a drain longitudinal groove 50 between the tub tray deck 30 and the bath area tray deck 40, which extend along the moving direction M, respectively.

A horizontal drainage groove 31 is formed in the tub tray table 30 so as to intersect the center of the movement direction M, and a first tub tray table 35 and a second tub tray table 36 are provided on both sides of the movement direction M of the horizontal drainage groove 31.

The portion of the vertical drain groove 50 adjacent to the horizontal drain groove 31 is a drain merging portion 56. The portion of the bath area tray table 40 adjacent to the drain merging portion 56 is a drain recess 60, and a drain port 61 is formed.

The drainage transverse grooves 31 and the drainage merging portions 56 form a continuous plane. The plane formed by the horizontal drain groove 31 and the drain merging portion 56 is provided with an inclination a that decreases from the horizontal drain groove 31 toward the drain recess 60. The drainage concave portion 60 is formed in a slightly stepped shape downward from the plane formed by the drainage transverse groove 31 and the drainage merging portion 56.

The inclination a is preferably set to 1 to 15 °, more preferably 1 to 10 °. If the inclination a is equal to or greater than the lower limit value of the preferable angle, the drain reaching the drain lateral groove 31 or the drain merging portion 56 can be easily guided to the drain port 61. If the inclination a is equal to or smaller than the upper limit value of the preferable angle, the drain recess 60 does not need to be deep enough.

The first and second bathtub tray decks 35, 36 have valley-like depressions. The valley-shaped depressions are formed such that the valleys 32 continuously increase in depth in the diagonal direction from the opposite sides (bathroom wall surface sides) of the drainage vertical grooves 50 at both ends in the moving direction M toward the boundary (merging portion) of the drainage merging portion 56 in the drainage horizontal grooves 31 and the drainage vertical grooves 50. According to this structure, water on the bath surface easily flows into the drainage vertical groove, and water can be efficiently drained.

More specifically, on the first bathtub tray deck 35 and the second bathtub tray deck 36, the valley lines 32 of the boundary (junction) between the drainage cross grooves 31 and the drainage junction 56 in the drainage longitudinal grooves 50 are formed diagonally from the opposite sides (bathroom wall surface side) of the both ends in the moving direction M from the drainage longitudinal grooves 50.

The drain longitudinal groove 50 side of the first bathtub tray deck 35 is a planar area 35a, and the drain longitudinal groove 50 side of the second bathtub tray deck 36 is a planar area 36a.

The height of the region 35a and the region 36a is set to be inclined B which decreases from the drainage groove 50 side toward the valley line 32 in the width direction N. In the moving direction M, an inclination D is provided which becomes lower from both end sides of the moving direction M toward the valley line 32.

The side of the first bathtub tray deck 35 opposite the drain longitudinal groove 50 is a planar area 35b, and the side of the second bathtub tray deck 36 opposite the drain longitudinal groove 50 is a planar area 36b.

The height of the region 35b and the region 36b is set to be inclined C that decreases from the opposite side of the drainage groove 50 toward the valley line 32 in the width direction N.

The inclination B is preferably set to 1 to 15 °, more preferably 1 to 10 °. If the inclination B is equal to or greater than the lower limit value of the preferable angle, a gap for accommodating the nozzle is easily formed between the bathtub 10 and the nozzle. In addition, if the inclination B is equal to or less than the upper limit value of the preferable angle, it is easy to ensure the flatness of the first bathtub tray deck 35 and the second bathtub tray deck 36.

The inclination C is preferably set to 3 to 10 °, more preferably set to 4 to 7 °. If the inclination C is equal to or greater than the lower limit value of the preferable angle, a gap for accommodating the nozzle is easily formed between the bathtub 10 and the nozzle. Further, if the inclination C is equal to or less than the upper limit value of the preferable angle, it is easy to ensure the flatness of the first bathtub tray deck 35 and the second bathtub tray deck 36.

The inclination D is preferably set to 1 to 5 °, more preferably 1 to 3 °. If the inclination D is equal to or greater than the lower limit value of the preferred angle, the drain reaching the first bathtub tray deck 35 or the second bathtub tray deck 36 can be quickly guided to the drain cross groove 31 or the drain merging portion 56. In addition, if the inclination D is equal to or less than the upper limit value of the preferable angle, it is easy to ensure the flatness of the first bathtub tray deck 35 and the second bathtub tray deck 36.

Screen-shaped groove covers 71 are respectively placed on both sides of the drainage merging portion 56 in the drainage vertical groove 50. Further, decorative groove covers 72 are respectively placed on both outer sides thereof.

The screen-like trough cover 71 receives the drain from the bathtub drain cock 14 and directs it to the drain pod 50. The upper surface of the screen-shaped groove cover 71 is concavely curved so as not to contact the drain outlet 15 of the bathtub drain cock 14.

The bottom surface of the vertical drain tank 50 is also provided with an inclination J which descends in the direction of the drainage merging portion 56 at the portions where the screen-like tank cover 71 and the decorative tank cover 72 are provided.

The inclination J is preferably set to 1 to 10 °. If the inclination J is equal to or greater than the lower limit value of the preferable angle, the drain reaching the drain vertical groove 50 can be easily guided to the drain merging portion 56. If the inclination J is equal to or smaller than the upper limit value of the preferred angle, the drain merging portion 56 and the drain concave portion 60 do not need to be deep enough.

The bath area tray deck 40 is configured to continuously descend from its peripheral edge portion toward the drain vertical groove 50. According to the structure, water on the table surface of the tray in the bathing area easily flows into the water draining longitudinal groove, and water can be effectively drained.

More specifically, two valleys 42 are formed on the bath area tray table 40 from both ends in the movement direction M at the boundary with the drainage vertical groove 50 toward the boundary with the drainage concave portion 60.

An inclination E is provided between both ends of the movement direction M at the boundary with the drainage groove 50, and is lowered toward the two valleys 42 along the width direction N.

In addition to this, the trough and ridge are formed appropriately on the bath area tray table 40 so as to incline downward toward the boundary with the drain recess 60.

Next, as a bathroom structure of the present embodiment, a bathroom structure in which the bathtub unit 1 is disposed on the upper surface of the waterproof tray shown in fig. 5 will be described.

Fig. 6 and 7 show a state in which the bathtub unit 1 is disposed at the end (left side as viewed from the bath area) of the waterproof tray in the movement direction M in the bathroom structure of the present embodiment. In the bathtub unit 1 of fig. 6, the bathtub skirt 9 and the like are omitted for the sake of clarity of the arrangement position of the bathtub 10, and only the bathtub 10, the nozzle 2, and the bathtub drain cock 14 are shown.

As shown in fig. 6, the bathtub 10 is disposed above the bathtub tray deck 30 and the sieve-like trough cover 71 placed on the drain vertical trough 50, and the center of the movement direction M of the bathtub 10 is located at substantially the center of the movement direction M of the sieve-like trough cover 71.

Fig. 7 is a view showing the positional relationship between the bottom surface of the bathtub and the waterproof tray in the section VII-VII in this state, and the vicinity of the bottom surface 20 of the bathtub. The section VII-VII is a section taken along the width direction N at the center of the movement direction M of the bathtub 10, in which the nozzle 2 and the bathtub drain cock 14 are present. That is, the VII-VII profile is a profile of one end of the "both ends of the range of movement of the nozzle with movement of the tub unit" in the present invention.

As shown in fig. 7, the waterproof tray of the present embodiment is configured by fitting the bathtub tray 17 and the bath area tray 18 at the fitting portion 19.

The upper surface of the bathtub tray 17 forms part of the bathtub tray deck 30 (first bathtub tray deck 35 in section VII-VII) and the drain chute 50, and the upper surface of the bathing zone tray 18 forms the remainder of the bathing zone tray deck 40 and the drain chute 50.

The bathtub tray 17 is supported by a plurality of support feet 70.

In section VII-VII, the portion of the valley line 32 of the primary bathtub tray deck 35 is at a height H2. The drain groove 50 side of the valley line 32 is inclined B low on the valley line 32 side, and a slightly flat surface is formed at the front end of the height H3. The valley line 32 side of the valley line 32 on the bathroom wall 75 side is set to a low inclination C, and the height of the first bathtub tray deck 35 on the bathroom wall 75 side (the side opposite to the drain longitudinal groove) is set to a height H1.

The heights H1, H2, H3 are in the following relationship.

H1＞H3＞H2

Since the height H3 is higher than the height H2, water on the tub tray deck 30 flows toward the drainage pod 50 even though there is a lowest point of the height H3 therebetween.

In the following description, the height H0 of the bath area tray table 40 at the boundary with the drain vertical groove 50 (except for the portion where the drain concave portion 60 is formed, the same applies hereinafter) is defined as the reference surface.

In the section VII-VII of the present embodiment, the height H1 is substantially equal to the height H0, but the height H1 is preferably slightly higher than the height H0. For example, the height H1 is preferably set to be 10mm higher than the height H0. By making the height H1 slightly higher than the height H0, even if the gradient of the valley line 32 is gentle, the height H2 can be easily set at a sufficiently low position, and a gap for accommodating the nozzle 2 and the nozzle pipe 3 can be easily formed.

In the drainage vertical groove 50, a first drainage groove 51 and portions of a first cover placement area 53 (bathtub tray deck 30 side) and a second cover placement area 54 (bathtub tray deck 40 side) on both sides thereof are formed on the upper surface of the bathtub tray 17. Further, on the bath area tray table 40 side of the second cover placement area 54, a middle section 55 and a second drain groove 52 are formed on the upper surface of the bath area tray 18. The engaging portion 19 of the tub tray 17 and the bath area tray 18 is formed from the second cover placement area 54 at the interface of the second cover placement area 54 and the middle portion 55.

The first drain groove 51 is larger and deeper than the second drain groove 52. Ribs on both ends of the screen-shaped groove cover 71 in the moving direction M are placed in the first cover placement area 53 and the second cover placement area 54, thereby supporting the screen-shaped groove cover 71. The screen-shaped gutter cover 71 covers the upper sides of the first and second drain gutters 51 and 52.

The drain water flowing out from the bathtub drain cock 14 enters the second drain tank 52 through the screen-like tank cover 71, and then flows into the first drain tank 51 or the drain merging portion 56.

The bathing area tray deck 40 is adjacent to the second drain trough 52. The portion of the bath area tray deck 40 adjacent to the second drain groove 52 (the portion adjacent to the drain longitudinal groove 50) is the height H0 of the reference surface. The smaller the difference between the height H0 and the height H1, the more the height reference surface of the entire waterproof tray can be made the same, and thus the construction becomes easy.

The smaller the difference between the height H0 and the height H3 of the reference surface of the portion of the bath area tray deck 40 adjacent to the second drain groove 52 (the portion adjacent to the drain longitudinal groove 50), the smaller the difference between the heights of the interfaces of the tub tray deck and the bath area tray deck, and thus the safety of the caregivers can be easily ensured.

A plurality of ribs protruding downward are provided on the tub bottom outside 21 of the tub 10 at positions not interfering with the nozzle piping 3 and the like, for example, at positions near four corners of the tub bottom outside 21.

These ribs contact the bathtub tray deck 30, the sifter-like trough cover 71, and the decorative trough cover 72 to support the bathtub 10, whereby the bathtub floor outside 21 in section VII-VII is in a position separated from the bathtub tray deck 30.

The bathtub unit 1 is pressed in either direction of the moving direction M, and these ribs slide on the bathtub tray deck 30 or the like and can move in the moving direction M.

As described above, the bottom surface 20 of the bathtub is provided with the slope G which is lowered from the bathroom wall 75 side toward the bathtub drain cock 14. The tub bottom 20 is formed in a uniform thickness as a whole. Therefore, the same inclination G is provided on the tub bottom outside 21 and the tub bottom inside 22.

In the present embodiment, the bathtub drain plug 14 is provided at the lowest position on the side of the drain vertical groove 50, and the entire width direction N of the bathtub bottom surface 20 is inclined in the same direction. Therefore, the height of the bath wall surface 75 side of the bath bottom outside 21 can be increased as compared with the case where the drain plug is provided at the center in the width direction N, and a gap can be easily provided between the bath bottom outside 21 and the bath tray table 30.

In section VII-VII, the nozzle 2 is located on the valley 32 of the bathtub tray deck 30. That is, since the portion of the nozzle 2 protruding from the tub bottom outside 21 and the nozzle pipe 3 connected to the nozzle 2 are located at the portion that becomes the lowest point (height H2) of the tub tray deck 30, they are accommodated in the space between the tub bottom outside 21 and the tub tray deck 30 and do not contact the tub tray deck 30.

When the bathtub unit 1 is moved from the position shown in fig. 6 toward the center of the movement direction M on the waterproof tray, the passing position of the nozzle 2 gradually moves away from the valley line 32. However, since the area 35b is the same height along the moving direction M, the first bathtub tray deck 35 does not contact the nozzles 2 and the nozzle piping 3 when the nozzles 2 pass through the area 35 b.

Next, in the bathroom structure of the present embodiment, the bathtub unit 1 is moved to the center in the movement direction M on the waterproof tray as shown in fig. 8 and 9. In fig. 8, only the tub 10, the nozzle 2 and the tub drain 14 are also shown for the tub unit 1.

As shown in fig. 8, the bathtub 10 is disposed above the bathtub tray deck 30 and the screen-shaped trough cover 71 placed on the drain vertical trough 50, and the center of the movement direction M of the bathtub 10 is located at the drain merging portion 56 at the center of the movement direction M of the drain vertical trough 50.

Fig. 9 is a view showing the positional relationship between the bottom surface of the bathtub and the waterproof tray in the section IX-IX in this state, and the vicinity of the bottom surface 20 of the bathtub. The section IX-IX is a section taken along the width direction N at the center of the movement direction M of the bathtub 10, in which the nozzle 2 and the bathtub drain cock 14 are present. That is, the IX-IX profile is a profile in the middle of the "both ends of the range in which the nozzle moves with the movement of the bathtub unit" in the present invention.

The bathtub tray 17 is supported by a plurality of support feet 70. In the cross section of fig. 9, the upper surface of the bathtub tray 17 constitutes a drainage merging portion 56 of the drainage cross grooves 31 and the drainage vertical grooves 50 of the bathtub tray deck 30. As described above, in the section IX-IX, the drainage cross-groove 31 continues at the inclination a with the drainage merging point 56.

In the section IX-IX, the height H6 of the drain chute 31 along the bathroom wall 75 is significantly lower than the height H0 of the reference surface.

By the difference between the height H6 and the height H0, the first and second bathtub tray decks 35 and 36 are higher than the horizontal drain grooves 31, so that water can be quickly drained to the horizontal drain grooves 31, and a space capable of accommodating the nozzles 2 and the nozzle pipes 3 is easily formed between the first and second bathtub tray decks 35 and 36 and the tub bottom outside 21.

A plane continuous with the drainage merging portion 56 is formed on the upper surface of the bath area tray 18 adjacent to the fitting portion 19. The drain recess 60 is formed slightly lower than the plane. The side of the drainage concave portion 60 opposite to the fitting portion 19 in the width direction N is a bath area tray table 40. The bath area tray table 40 is inclined so as to descend in the width direction N toward the drain recess 60 while maintaining a height substantially equal to the height H0 of the reference surface.

A drain port 61 is provided in the drain recess 60, and a drain pipe 62 for guiding the drain to the outside of the bathroom is connected to the drain port 61. The drain 62 passes under the bath tray deck 40 of the bath tray 18 to the outside of the bath.

In section IX-IX, as can be seen from fig. 9, a sufficient space for accommodating the nozzle 2 and the nozzle pipe 3 exists between the tub bottom outside 21 and the tub tray table 30.

In a state where the bathtub unit 1 is further moved and arranged at the end (right side as viewed from the bath area) of the movement direction M on the waterproof tray, a cross section taken along the width direction N at the center of the movement direction M of the bathtub 10 is the same as the VII-VII cross section shown in fig. 7. The cross section is a cross section at the other end of the "both ends of the range in which the nozzle moves with the movement of the bathtub unit" in the present invention.

In this section, as in the case described with reference to fig. 7, the nozzle 2 is also located on the valley line 32 of the bathtub tray deck 30. That is, since the portion of the nozzle 2 protruding from the tub bottom outside 21 and the nozzle pipe 3 connected to the nozzle 2 are located at the portion that becomes the lowest point (height H2) of the tub tray deck 30, they are accommodated in the space between the tub bottom outside 21 and the tub tray deck 30 and do not contact the tub tray deck 30.

In addition, in moving the bathtub unit 1 from the position of fig. 8 to the other terminal end along the moving direction M on the waterproof tray, the passing position of the nozzle 2 is separated from the valley line 32. However, since the area 36b is the same height along the moving direction M, the second bathtub tray deck 36 does not contact the nozzles 2 and the nozzle piping 3 until the nozzles 2 pass through the area 36b and reach the valley line 32.

As described above, according to the bathtub unit 1 of the present embodiment, the height of the bath area tray deck 40 is easily made the same as the height of the tub bottom inner side 22, so that the safety of the care-giver is easily ensured, the work load when the bathtub unit 1 (including the bathtub 10) is moved is small, and the efficient automatic cleaning of the bathtub 10 can be performed.

In the above embodiment, the specific structure of the bathtub tray deck 30 has been specified, but the structure is not particularly limited as long as a space is created between the bathtub 10 and the portion of the nozzle 2 protruding downward from the bathtub bottom surface outside 21 and the nozzle pipe 3 can be accommodated.

For example, in the above embodiment, the heights of the regions 35b and 36b are constant in the moving direction M, but an inclination that becomes lower toward the drainage transverse groove 31 may be provided. In the above embodiment, the first bathtub tray deck 35 and the second bathtub tray deck 36 have the planar areas 35a and 35b, and the areas 36a and 36b, respectively, but some or all of them may be curved. Thus, each distinct valley 32 may not be present.

In order to facilitate the movement on the bathtub tray deck 30, a rib protruding downward from the tub bottom surface 20 toward the lower side of the tub bottom surface outside 21 may be provided, or a wheel may be provided instead of the rib. In the above embodiment, the nozzle 2 is arranged at the center of the tub bottom 20, but the position of the nozzle 2 may be located at the bottom of the tub bottom 20 or may be deviated from the center.

Further, various modifications can be made within the scope not departing from the gist of the present invention.
