Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to the structure of a unitized deodorizing duct provided in a prefab toilet.

(Prior Art) When assembling a conventional unit toilet, the pipes arranged along the side wall are surrounded by a structure, and the surface of this structure is disguised as a counter part, and the front part of the counter part is contacted. Equipment such as toilet bowls are attached. A deodorizing duct is provided in this structure for deodorizing the toilet room.This deodorizing duct connects the exhaust grill normally installed along the floor below the front of the counter with the exhaust pipe connected to the suction fan. It is connected and sucks the odor in the toilet room from the exhaust grill and exhausts it to the outside through the deodorizing duct and the exhaust pipe. Further, since this exhaust is normally performed at a high place in the building, the height of the exhaust pipe cannot be made too low, and therefore the deodorizing duct is arranged almost vertically in the structure.

(Problems to be solved by the invention) Therefore, the arrangement of the deodorizing duct directly affects the other pipes in the structure, and the deodorizing duct occupies a large proportion of the side passage area of the structure. In such a case, the degree of freedom in arranging the other pipes is pressed, and it is necessary to arrange the pipes so as not to get in the way as much as possible.

(Means for Solving the Problem) In order to solve the problem, the present invention is designed to fit the depth width of the suction duct within the thickness width of the front frame of the structure among the deodorization ducts including the deodorization pipe and the suction duct. Formed into
It was placed side by side with the front frame in front of the structure.

(Operation) Since the side surface passage holes of the structure can be fully utilized, the degree of freedom in arranging other pipes is increased.

(Embodiment) An embodiment of the structure of the deodorizing duct of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a side view showing an assembled state of a unit toilet, and FIG.
The figure is a perspective view showing a state before assembly of the unit toilet,
The figure shows the deodorizing duct of the present invention, (A) is a front view,
(B) is a side view.

As shown in FIGS. 1 and 2, the unit toilet includes a counter portion 3 that rises from the floor surface 1 along the side wall 2,
The counter portion 3 is formed so as to cover the pipes arranged along the side wall 2, and the structure 4 serves as a frame body thereof. This structure 4 is provided with front frames 4a, 4a on the front surface and its rear surface is in contact with the side wall, and a deck 5 is provided on the upper surface.
And the front plate 7 is attached to the front face with the toilet attachment member 6 interposed therebetween. The front plate 7 is provided with an insertion hole 7a for passing a drainage connecting pipe extending rearward from the back of the toilet 8 and its lower end does not reach the floor surface 1,
An opening 10 as an exhaust grill is formed below the front plate 7 and with a skirting board 9 arranged along the floor.

In addition to the deodorizing duct 11 that is a combined body, a water supply pipe 16 for supplying purified water, a drainage ventilation pipe 17, an exhaust pipe (not shown), and the like are housed in the structure 4, which will be described later. So that it is connected to a part of the deodorizing duct 11.

This deodorizing duct 11 is a combination of a deodorizing pipe 12 having a circular cross section and a suction duct 13 having a rectangular cross section.
As shown in FIG. 1, 3 is formed to fit within the width of the frame 4a of the structure 4. Further, the deodorizing pipe 12 of the deodorizing duct 11 is, as shown in FIG.
12a has a large diameter with a step to connect with the above-mentioned exhaust pipe, and the inner diameters of the joint portions 12a, 12a are formed in a taper shape that slightly expands toward the end so that the exhaust pipe can be fitted. I am configuring. Also this deodorizing tube 12
A connecting duct 12b is integrally attached to the central side surface of the, and the connecting duct 12b is attached with a slanting angle (angle β) in the horizontal direction as well as a downward inclination (angle α). The upper end of the suction duct 13 described later can be fitted. These inclination angles (α) and inclination angles (β) are designed so that the air flow will be smooth during suction by the suction fan provided at the extension of the duct in the inclination angle (β) direction. In the case of this embodiment, α
Is set to 16 degrees and β is set to 30 degrees. Also this deodorizing tube 1
The material of No. 2 is hard polyvinyl chloride.

On the other hand, the suction duct 13 includes an upper duct 14 and a lower duct 15.
Connection duct 1 of the deodorizing pipe 12
The upper duct 14 press-fitted into the lower end of 2b is bent at a bent portion 14a by changing its direction in the vertical direction with a predetermined curvature, and is fitted to the upper end of the lower duct 15 below. Therefore, on the peripheral wall of the lower end portion of the upper duct 14, the protruding portion 14 protruding outward is formed.
b is formed, and the protrusion 15a of the lower duct 15 described later is formed.
Engaged with the inner surface. The lower duct 15 is engaged with the lower end of the upper duct 14 by fitting the lower end of the upper duct 14 with the protrusion 15a on the upper peripheral wall.
A lower end portion having a width c and having a reduced thickness is formed so as to project to the side far from the deodorizing pipe 12, and a suction port 15d is provided on the lower surface. Therefore, the suction port 15d approaches the opening 10 serving as an exhaust grill provided in the lower portion of the front surface of the counter portion 3 to enhance the suction effect.

The suction duct 13 including the upper and lower ducts 14 and 15 is made of acrylic resin.

When such a deodorizing duct 11 is incorporated into the structure, the suction duct 13 portion thereof is completely contained within the width of the front frame 4a, which increases the degree of freedom in selecting the arrangement of other pipes.

(Effects of the Invention) Since the present invention is configured as described above, not only is it possible to freely select the arrangement of the piping in the structure, but also the front and rear width of the structure itself can be reduced. It has the effect of being able to effectively utilize the space.
