Description

  The present invention relates to a bathtub installation structure in a unit bath (a bathtub with a washing area) in which a bathtub pan and a washing area pan are integrated and the bathtub is disposed on the bathtub pan.

  In general, a unit bath incorporated in a house, an apartment house, or the like has a structure in which a bathtub pan for placing a bathtub and a washing pan are integrated in order to prevent the bath water from leaking out of the bathroom. Then, wall panels and door panels are erected on the outer four sides of the bathtub pan and the wash basin pan, and a ceiling panel is disposed to constitute a bathroom. In the bathroom configured as described above, in order to make the bathtub one step lower than the washing place as a recent trend, the bathtub pan is formed in a state of being dropped below the washing place pan (for example, Patent Document 1).

  FIG. 11 and FIG. 12 are diagrams showing the construction state of the bathtub 101, the bathtub pan 102, and the wash basin 103 in the unit bath according to such a design policy, and the support device arranged on the building floor B as shown in FIG. The bathtub pan 102 and the washing pan 103 are supported by H, and the bathtub 101 is disposed on the bathtub pan 102. And the caulking agent is filled in the contact part of the flange of the bathtub 101 and the wall panel, and bath water is prevented from leaking out from the side part and the rear part of the bathtub 101.

In the unit bath constructed in this way, a detachable apron 104 is arranged so that the front surface of the bathtub 101 can be opened in order to enable inspection and repair of the piping / hot water supply equipment C to the bathtub 101. .

That is, in the first aspect of the present invention, the bathtub pan and the washing place pan are integrally formed so that no step is formed at the boundary portion, and the bathtub having a plurality of casters at the bottom is disposed on the bathtub pan. To do.

  According to a second aspect of the present invention, in the first aspect of the present invention, in the state in which the bathtub is arranged at a fixed position, a recess is formed on the surface of the bathtub pan corresponding to the fixed position of the caster of the bathtub.

  According to a third aspect of the present invention, in the second aspect of the present invention, the depth of the concave portion facing the washing area is formed shallow, and the horizontal state of the bathtub body is maintained by absorbing the inclination due to the water gradient.

  In the invention of claim 4, the bathtub pan and the washing pan are integrally formed so as not to form a step at the boundary portion, and the bottom of the bathtub is disposed in a state where the bathtub is disposed at a fixed position on the bathtub pan. A recess member is formed on the surface of the bathtub pan corresponding to the fixed position of the caster provided in the case, and the end of the flange of the bathtub body engages when the wheel of the caster is immersed in the recess portion. Is attached to the bathroom wall.

  According to the first aspect of the present invention, no step is formed between the bathtub pan and the washing place pan, and since the plurality of casters are fixed to the bottom of the bathtub, the bathtub body can be moved to the washing place side, Thereby, the surface of the bathtub pan of the part in which the bathtub was arrange | positioned in the home position can be cleaned.

  According to invention of Claim 2, since the recessed part was formed in the surface of the bathtub pan, rolling of the wheel of the caster fixed to the bathtub by this recessed part was blocked | prevented, and the exact positioning of a bathtub became possible, The stable arrangement | positioning of the bathtub main body is attained.

  According to invention of Claim 3, the inclination by a water gradient is absorbed and the horizontal state of a bathtub main body can be maintained by forming the depth of the recessed part which faces the washing place side of a bathtub pan shallowly.

  In invention of Claim 4, when the wheel of a caster immerses in the recessed part of a bathtub pan, since the edge part of the flange of a bathtub main body engages with the locking member attached to the wall surface of a bathroom, the fixed position of a bathtub main body Fixing to is ensured.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the part which is common in the conventional description, and the description is abbreviate | omitted.

  FIG. 1 shows a construction state of a bathtub 1 and a bathtub / washing area pan 2 in a unit bath according to the present invention. The bathtub / washing area pan 2 is configured such that no step is formed at the central boundary. A downwardly inclined water gradient is formed from the outer periphery toward the drain port. And the recessed part 2a * 2b is formed in the position corresponding to the caster 3 fixed to the bottom part of the bathtub 1 in the bathtub pan part of this bathtub / washing area bread | pan 2. As shown in FIG.

  As shown in FIG. 2, the recessed portions 2a and 2b are formed such that the depth of the recessed portion 2b facing the washing area is shallower than the recessed portion 2a on the wall surface side. Thereby, when the wheel 3a of the caster 3 of the bathtub 1 is positioned in the recessed portions 2a and 2b, the diameter of the wheel 3a is the same, so the height position of the wheel 3a facing the washing area is relatively high. Thus, the inclination θ of the bathtub pan portion due to the water gradient is absorbed, and the horizontal level HL2 between the wheels 3a can be matched with the reference horizontal level HL1, and the horizontal state of the bathtub 1 can be maintained.

  FIG. 3 is an enlarged view showing a state in which the bathtub 1 is disposed in the bathtub pan portion of the bathtub / washing area pan 2 configured as described above, and the internal structure of the bathtub 1 is covered with the apron 1a. Even in the case of being placed in a bathroom as shown in FIG. 4, the sense of unity with the room is not impaired.

  When the bathtub 1 is disposed in this way and the wheel 3a of the caster 3 is immersed in the recessed portions 2a and 2b, the upward gradient of the recessed portions 2a and 2b has an effect of becoming a wedge with respect to the wheel 3a of the caster 3. Therefore, rolling of the wheel 3a is prevented, and the bathtub 1 can be stabilized at a fixed position. Furthermore, in the present invention, the height difference before and after the wheels 3a of the casters 3 are immersed in the recessed portions 2a and 2b (FIG. 2, reference symbol h1) is used to ensure the fixed state of the bathtub 1.

  Such a structure fixes the locking member 4 to the wall panel D of the bathroom as shown in FIG. 1, and the end of the flange 1b of the bathtub 1 is formed in the opening formed between the locking member 4 and the wall panel D. To engage. 5 (A) and 5 (B) show a state immediately before the wheels 3a of the casters 3 of the bathtub 1 are immersed in the recessed portions 2a and 2b, that is, the wheels 3a of the casters 3 The state is on the surface of the washing pan 2 and the bathtub 1 is in a high position with respect to the locking member 4.

  When the bathtub 1 is further pushed in the arrangement direction from the state of FIGS. 5A and 5B, the end of the flange 1b faces the opening of the locking member 4 as shown in FIG. The wheel 3a faces the recessed portion 2a. When the bathtub 1 is further pushed in the arrangement direction, the wheel 3a of the caster 3 is immersed in the recessed portion 2a as shown in FIG. 7 (B), and the end of the flange 1b of the bathtub 1 is accordingly moved to FIG. Engage with the locking member 4 as shown in FIG.

  Next, in the bathtub installation structure according to the present invention configured as described above, a case where the bathtub 1 is moved in the bathroom will be described. As shown in FIG. 8A, the wheel 3a of the caster 3 of the bathtub 1 is immersed in the recesses 2a and 2b, and the end of the flange 1b is fixed to a fixed position while being engaged with the locking member 4. First, the bathtub 1 is pulled up slightly, and the engagement between the end of the flange 1b and the locking member 4 is released.

  And since the wheel 3a of the caster 3 rides on the surface of the bathtub / washing area pan 2 from the recessed parts 2a, 2b by pulling the bathtub 1 to the washing area side, it can be moved as it is. FIG. 8B shows a state in which the bathtub 1 is pulled out while the drain pipe P is connected between the drain port 1c of the bathtub 1 and the drain port 2c of the bathtub / washing area pan 2. FIG. These show the state which removed the drainage pipe P from the drain outlet 2c of the bathtub 2 and the washing-room pan 2, and pulled out the bathtub 1 largely.

  FIG. 9 shows an example in which the round-shaped bathtub 1 is employed, and is effective for realizing the present invention when there is no room in the bathroom. That is, as in the above-described example, when the planar shape of the flange of the bathtub 1 is a square, the bathroom must have a width including the diagonal distance. However, by adopting a round-shaped bathtub, the width of the bathroom can be a length including the distance in the longitudinal direction of the bathtub.

  FIG. 10A shows a state in which the bathtub 1 is disposed in the bathtub pan portion of the bathtub / washing area pan 2 based on such conditions, and the wheels 3a of the casters 3 of the bathtub 1 are formed in the recessed portions 2a and 2b. It is immersed and the end of the flange 1b engages with the locking member 4 and is fixed in place. When the bathtub 1 is moved in the bathroom from such a state, the bathtub 1 is first lifted slightly, and the engagement between the end of the flange 1b and the locking member 4 is released.

  And since the wheel 3a of the caster 3 rides on the surface of the bathtub / washing area pan 2 from the recessed parts 2a, 2b by pulling the bathtub 1 to the washing area side, it can be moved as it is. FIG. 10 (B) shows a state in which the bathtub 1 is pulled out while the drain pipe P is connected between the drain port 1c of the bathtub 1 and the drain port 2c of the bathtub / washing area pan 2. FIG. These show the state which removed the drainage pipe P from the drain outlet 2c of the bathtub 2 and the washing-room pan 2, and pulled out the bathtub 1 largely.

  As described above in detail, according to the bathtub installation structure of the present invention, since the bathtub 1 can be moved from the home position to the washing place side, the bathtub pan portion that has been covered by the bathtub 1 until then is placed in the bathroom. It can be exposed, and this portion can be easily cleaned, and the accumulated mold and waste can be removed to keep the hygienic state high.
