  The bathroom door structure 100 according to the present embodiment is provided at an entrance between the bathroom and a dressing room. The bathroom door structure 100 includes a frame 110, a door body 120, a hinge 130, a ventilation part 140, a tight material 150, and a holder 160. In the bathroom door structure 100 illustrated in FIG. 2, the number of the holders 160 is two, but is not limited thereto.

  The frame 110 is provided around the entrance / exit between the bathroom and the dressing room. Specifically, the frame 110 includes a first frame member 111 provided at the right end of the entrance, a second frame member 113 provided at the left end of the entrance, and a third frame provided at the upper end of the entrance. It has the frame material 115 and the 4th frame material 117 provided in the lower end part of an entrance / exit.

The door main body 120 is attached to the frame 110 through a hinge 130 so as to be opened and closed. The door main body 120 has a face material formed of any one of tempered glass, polycarbonate, and acrylic resin, and exhibits transparency or translucency. In addition, the door main body 120 does not have a ridge, and a face material formed of any one of tempered glass, polycarbonate, and acrylic resin is exposed at the end of the door main body 120.
In the present specification, the term “tempered glass” refers to a glass in which a compressive stress layer is formed on the surface of the glass and the strength against the action of external force and temperature change is increased compared to a glass having no compressive stress layer. It shall be said.
In the specification of the present application, “transparency or translucency” is not limited to the property that the transmittance is 100 percent (%), and the transmittance is not zero at least for light having a wavelength of visible light. It shall be a property.

  The hinge 130 attaches the door main body 120 to the frame 110 so that it can be opened and closed. The hinge 130 is called a gravity hinge, for example, and supports the door main body 120 so that the door main body 120 rotates in a closing direction due to its own weight.

  The ventilation unit 140 is provided on the frame 110. Specifically, as illustrated in FIG. 2, the ventilation unit 140 is provided inside the third frame member 115. The ventilation unit 140 allows air to flow from the dressing room to the bathroom, while suppressing air flow from the bathroom to the dressing room. Specifically, as illustrated in FIG. 4, the ventilation unit 140 includes a ventilation unit main body 141 and a damper unit 143. In the ventilation unit main body 141, a gap between the third frame member 115 and a third inner frame member 175, which will be described later, serves as an air passage 142 that connects the dressing room and the bathroom. The damper part 143 is pivotally supported by the shaft part 145 so as to be rotatable with respect to the ventilation part main body 141. As indicated by arrows A1 and A2 illustrated in FIG. 4, the damper portion 143 can rotate about the shaft portion 145 to open and close the air passage 142.

  When the pressure in the bathroom and the pressure in the dressing room are substantially the same, the damper portion 143 is lowered by its own weight in the direction of the arrow A1 shown in FIG. In addition, when the mist sauna is used in the bathroom and hot water is discharged in the form of a mist, the damper portion 143 tends to rotate in the direction of the arrow A1 shown in FIG. Then, the tip of the damper portion 143 comes into contact with the third inner frame member 175 (the wall of the air passage 142). Therefore, the damper part 143 does not open the ventilation path 142. Thereby, the ventilation part 140 suppresses the flow of the air from a bathroom to a dressing room.

On the other hand, for example, when a ventilation fan in the bathroom is driven and the atmospheric pressure in the bathroom becomes negative, the damper portion 143 has an arrow A2 shown in FIG. Rotate in the direction to open the air passage 142. Thereby, the ventilation part 140 accept | permits the flow of the air from a dressing room to a bathroom.
In addition, the ventilation part 140 is replaced with the 3rd frame material 115 instead of using the clearance gap between the 3rd frame material 115 and the 3rd inner frame material 175 as a ventilation path like this embodiment. In addition, a ventilation unit with a built-in air passage and a damper portion may be incorporated.

  As shown in FIG. 2, an inner frame 170 is provided on the inner surface of the frame body 110 (the door body 120 side). Specifically, as illustrated in FIG. 2 and FIG. 3, the inner frame 170 includes a first inner frame member 171 provided inside the first frame member 111 and an inner side of the second frame member 113. A second inner frame member 173 provided on the inner side of the third frame member 115 and a third inner frame member 175 provided on the inner side of the third frame member 115. The first inner frame material 171 overlaps the dressing room side at the right end of the door body 120 in a closed state. The second inner frame member 173 overlaps the undressing room side at the left end of the door body 120 in a closed state. The third inner frame member 175 overlaps the dressing room side of the upper end portion of the door body 120 in the closed state.

  As shown in FIGS. 3 and 4, a tight material receiving portion 180 is provided inside each of the first inner frame material 171 and the second inner frame material 173. As shown in FIG. 4, a tight material receiving portion 180 is provided inside each of the third inner frame material 175 and the fourth frame material 117.

  The tight material receiving portion 180 holds the tight material 150. In other words, the tight material 150 is held by the tight material receiving portion 180. The tight material 150 is made of, for example, rubber and has elasticity. The tight material 150 maintains airtightness between the door body 120 and the frame body 110 in a state where the door body 120 is closed. The holding structure for the tight material 150 will be described in detail later.

  As shown in FIG. 3, the holder 160 is provided on the frame 110 (the first frame member 111 in the present embodiment). The holder 160 maintains the posture of the door body 120 in a state where the tight material 150 keeps the airtightness between the door body 120 and the frame body 110 by the closing operation of the door body 120. Specifically, as illustrated in FIG. 3, the holder 160 includes a first holder main body 161, a second holder main body 162, and a spring 165. The spring 165 is a space inside the holder 160 and is provided so that the first holder body 161 can swing with respect to the second holder body 162.

  When the door main body 120 performs the closing operation as indicated by an arrow A <b> 3 illustrated in FIG. 3, the distal end portion 121 of the door main body 120 comes into contact with the first holder main body 161. Then, the first holder main body 161 receives a force from the distal end portion 121 of the door main body 120 and moves in the direction of the arrow A4 shown in FIG. 3 while resisting the biasing force of the spring 165. Then, the front end portion 121 of the door main body 120 moves over the first holder main body 161 toward the tight material 150 and comes into contact with the tight material 150.

  When the distal end portion 121 of the door main body 120 gets over the first retainer main body 161, the first retainer main body 161 is released from the force received from the distal end portion 121 of the door main body 120 and receives the biasing force of the spring 165. It moves in the direction of arrow A5 shown in FIG. On the other hand, since the tight material 150 has elasticity, when it abuts on the door main body 120, the door main body 120 is urged toward the first holder main body 161 (the side on which the door main body 120 opens). Therefore, as shown in FIG. 3, the distal end portion 121 of the door body 120 is sandwiched between the first holder body 161 and the tight material 150. Thereby, the holder 160 maintains the posture of the door body 120 in a state where the tight material 150 holds the airtightness between the door body 120 and the frame body 110 by the closing operation of the door body 120. The mounting structure of the holder 160 will be described in detail later.

  As shown in FIGS. 2 and 3, the door main body 120 is provided with a grip 191. As shown in FIG. 4, a water return 193 is provided at the lower end of the door body 120. The water return 193 can suppress the flow of water from the bathroom to the dressing room. In the present specification, “water” includes not only cold water but also heated hot water.

  According to the present embodiment, when the door main body 120 is closed, the tight material 150 maintains the airtightness between the door main body 120 and the frame body 110. Moreover, the ventilation part 140 which permits the flow of the air from a dressing room to a bathroom suppresses the flow of the air from a bathroom to a dressing room. Therefore, when the door body 120 is closed, air does not leak from the bathroom to the dressing room, and the airtightness in the bathroom is maintained.

  The holder 160 maintains the posture of the door main body 120 in a state where the tight material 150 holds the airtightness between the door main body 120 and the frame body 110 by the closing operation of the door main body 120. Therefore, the door main body 120 only closes. Can create an airtight condition in the bathroom. Further, since the holder 160 is provided not on the door body 120 but on the frame body 110, it is not necessary to provide accessories other than the hinge 130 and the grip portion 191 on the door body 120. Therefore, it is not necessary to provide a skirt around the face material formed of any one of tempered glass, polycarbonate, and acrylic resin, and the end face of the face material can be used as the end face of the door body 120. Therefore, it is possible to provide a luxury bathroom door structure 100 in which the entire door body 120 exhibits transparency or translucency. And it can suppress that air leaks from a bathroom to a dressing room by closing the door main body 120, using the door main body 120 which exhibits transparency or semi-transparency as a whole. Therefore, a mist sauna can be used in the bathroom.

  Further, the hinge 130 is a gravity hinge that closes the door body 120 with its own weight when a person releases the hand from the door body 120. Therefore, it is possible to prevent the door body 120 from being completely closed and from losing airtightness in the bathroom. For this reason, the inside of the bathroom can be kept airtight except when a person goes in and out.
