Description

  The present invention relates to a deodorizing device that prevents a bad odor in a downstream pipe from entering a washroom or the like from an inlet of washing waste water from a washing machine.

In the residential building, a drainage port (drainage fitting 71) through which drainage from the washing machine flows is provided on a floor surface F such as a washroom. Then, as shown in FIG. 7, there are many households in which the drainage hose 72 attached to the washing machine is directly inserted into the drainage fitting 71 and the drainage is discharged to the drainage pipe 73 on the downstream side. (FIG. 7A).
By the way, the washing wastewater does not generate an unpleasant odor in itself, and particularly in a house where the building age has passed, the drainage fitting 71 into which the wastewater from the washing machine flows, the drainage pipe 73, etc. include a kitchen sink and Sealing water (water trap) for blocking odor as applied to the toilet drain pipe was not performed. However, the drain pipe 73 connected to the drainage fitting 71 is connected to the drain pipe of other miscellaneous drainage on the downstream side. For this reason, organic matter such as washing wastewater and food wastewater is spoiled at the drainage retention portion on the downstream side of the drainage pipe 73, and the bad odor passes through the drainage pipe 73 from the gap between the drainage hose 72 and the drainage fitting 71. Entering a washroom or the like (FIG. 7 (b)) has been a problem in giving residents discomfort.

  On the other hand, Patent Document 1 and Patent Document 2 are provided with a deodorizing device (Patent Document 1: Drainage Trap, Patent Document 2: Drainage Discharge Unit) having a sealing function in the drainage opening that opens on the floor. It has been proposed to prevent backflow into the living space.

FIG. 1 is a diagram showing an outline of the deodorizing apparatus 1, and FIG. 2 is a front sectional view of a laundry drainage inlet to which the deodorizing apparatus 1 is attached. The upper half of FIG. 1A is a plan view (a view of FIG. 1B viewed from above), and the lower half is a back view (a view of FIG. 1B viewed from below).
The deodorizing device 1 includes a flow path forming unit 2 and a floor surface fixing unit 3.
The flow path forming part 2 is cylindrical as a whole, and the hose connecting part 11, the transition part 12 and the insertion part 13 are successively arranged from one side in the axial direction to the other side.

  The hose connecting portion 11 has an inner diameter that gradually decreases from the opening toward the back. As for the hose connection part 11, the internal diameter of the opening part is slightly larger than the outer diameter of the opening end of the discharge port 81 (refer FIG. 7) of the drainage hose 72 attached to a washing machine. The inner diameter of the end continuous to the transition portion 12 in the hose connecting portion 11 is slightly smaller than the outer diameter of the open end of the discharge port 81 of the drainage hose 72. The discharge port 81 of the drainage hose 72 has a cylindrical shape having the same shape and size regardless of the manufacturer of the washing machine.

The inner diameter of the transition part 12 gradually decreases from the side continuous with the hose connection part 11 toward the side continuous with the insertion part 13.
The insertion portion 13 has a constant cylindrical shape for both the inner diameter and the outer diameter, and is a portion that is inserted into the drainage fitting 71 at the time of construction (when attached to the floor surface F). The outer diameter of the insertion part 13 is smaller than the outer diameters of the hose connection part 11 and the transition part 12.

The floor surface fixing portion 3 includes a main body 20, a first pressing portion 21, and a second pressing portion 22.
The main body 20 is a thick plate-like portion that expands radially outward from the outer periphery of the transition portion 12 and has a circular shape in plan view. The outer end of the main body 20 continues to a cylindrical first pressing portion 21 that protrudes toward the insertion portion 13 with the axial center of the transition portion 12 or the like as the axial center. The degree of protrusion of the first pressing portion 21 toward the insertion portion 13 is smaller than the length of the insertion portion 13 (in the axial direction).

The second pressing portion 22 is a cylindrical portion that protrudes toward the insertion portion 13 in the vicinity of the inside of the first pressing portion 21. The degree of protrusion (length) of the second pressing part 22 is equal to the degree of protrusion of the first pressing part 21. Accordingly, the first pressing portion 21 and the second pressing portion 22 both have end surfaces 23 and 24 belonging to the same plane orthogonal to the axis of the flow path forming portion 2.
The floor surface fixing part 3 connects the first pressing part 21 and the second pressing part 22 in the radial direction, and screw hole installation parts 26, 26 arranged at intervals of 120 degrees with respect to the axis of the flow path forming part 2. , 26. As for the screw hole installation part 26, the screw hole 25 penetrates the center to the axial direction.

The deodorization apparatus 1 has a connection maintaining part 27 that protrudes outward from the outer surfaces of the hose connecting part 11, the transition part 12, and the floor surface fixing part 3 in the middle of the two screw hole installation parts 26, 26 in plan view. The connection maintaining unit 27 includes a fixing hole 28 that penetrates in a direction orthogonal to the axis of the flow path forming unit 2.
The deodorizing device 1 is made of so-called rubber such as nitrile rubber (NBR), styrene butadiene rubber (SBR), ethylene propylene diene rubber (EPDM), natural rubber (NR), or elastic body (elastomer) such as silicon rubber or urethane rubber. Preferably it is manufactured.

Further, the deodorizing device 1 made of these rubbers and elastic bodies to which an antistatic agent is added can reduce the adsorption of dust.
Next, attachment of the deodorizing apparatus 1 to the laundry drainage inlet will be described.
Referring to FIG. 2, a laundry drainage inlet provided in a washroom or the like where a washing machine is often arranged is formed by drainage fittings 71 that open to floor surface F. The drainage fitting 71 is held on the floor surface F by a flat plate-shaped flange portion 74, and a cylindrical portion 75 extending from the flange portion 74 into the floor surface F is connected to the drainage pipe 73.

  First, on the inner side in the radial direction of the second pressing portion 22 in the floor surface fixing portion 3 of the deodorizing device 1, a silicon-based, polyurethane-based or other caulking material CM is formed in an annular shape and slightly more than the end surface 24 of the second pressing portion 22. Highly served. The floor surface fixing portion 3 is formed by combining a cylindrical thick second pressing portion 22 that protrudes with a circular thick main body 20 having an axis center orthogonally crossed from one surface thereof. The caulking material CM can be accommodated inside.

Subsequently, the deodorizing apparatus 1 is configured such that the end surfaces 23 and 24 of the first pressing portion 21 and the second pressing portion 22 of the floor surface fixing portion 3 face the floor surface F, and the insertion portion 13 is located in the drainage fitting 71. Inserted into.
Note that the inner diameter of the second pressing portion 22 in the floor surface fixing portion 3 is sufficiently larger than the outer diameter of the flange portion 74 of the drainage fitting 71, and the outer diameter of the insertion portion 13 is smaller than the inner diameter of the drainage fitting 71.

The first pressing portion 21 and the second pressing portion 22 are pressed against the floor surface F, and the wood screws 76 are inserted into the three screw holes 25, 25, 25 in a state where the end surfaces 23, 24 are in contact with the floor surface F. Screw in to the floor F with a screwdriver. With this operation, the attachment of the deodorizer 1 to the laundry drainage inlet is completed.
As described above, the deodorizer 1 can be easily fixed to the floor F from the top of the drainage fitting 71 with a single screwdriver, even if the resident is not skilled in the work.

  The deodorizing apparatus 1 is configured such that the end surfaces 23 and 24 of the first pressing portion 21 and the second pressing portion 22 are in contact with the floor surface F to eliminate a gap between them, and the caulking material CM accumulated on the floor surface fixing portion 3 is The space between the floor surface fixing portion 3 and the floor surface F and the space between the second pressing portion 22 and the opening of the drainage fitting 71 are filled. After the deodorizing apparatus 1 is attached to the floor F, the space S (for example, the space in the bathroom) where the washing machine is placed and the inside of the drain pipe 73 are the flow paths (cavities) in the flow path forming unit 2. Communicate only.

When the discharge port 81 in the drainage hose 72 of the washing machine is fitted in the hose connection part 11 of the deodorization apparatus 1, the space S in which the deodorization apparatus 1 is attached and the drain pipe 73 are within the drainage hose 72. It is completely blocked except for the route.
The drain hose 72 is generally connected to the lowermost part of the washing machine (washing tub) so that the washing liquid and the rinsing liquid after washing can be discharged from the washing machine only by the head difference. On the other hand, since the hose connecting portion 11 of the deodorization device 1 is opened upward, the drainage hose 72 connected to the deodorization device 1 rises substantially vertically in the vicinity of the discharge port 81 and bends downward thereafter. Extends to the washing machine. That is, since the drainage hose 72 connected to the deodorization device 1 passes through a high position in the vicinity of the deodorization device 1, it is always rinsed between the washing machine and the deodorization device 1 after the washing machine is used once. A water-sealed part is generated.

The deodorization apparatus 1 having the flow path forming portion 2 that opens upward is provided in the drainage hose 72 in addition to preventing bad odors from entering the space S where the drainage fitting 71 opens directly from the drainage fitting 71. Occurrence of bad odors from the drainage hose 72 to the space S via the inside of the washing machine can be prevented by the formation of the sealed water portion.
The fixing hole 28 provided in the deodorization device 1 is connected to a hook 82 provided near the discharge port 81 of the drainage hose 72 by a binding band 83, a wire, etc., and from the hose connection part 11 of the drainage hose 72. This is to prevent the falling off.

The floor surface fixing portion 3B includes a main body 20, a first pressing portion 21B, and a second pressing portion 22. The main body 20 and the second pressing portion 22 are the same as those in the deodorizing device 1.

  The first pressing portion 21B protrudes toward the insertion portion 13 in a cylindrical shape with the axial center of the flow path forming portion 2 as the axial center. In the vicinity of the protruding end, the first pressing portion 21B gradually increases in inner diameter and outer diameter as both the inner peripheral surface and the outer peripheral surface approach the end. The shape of the cross section including the axial center of the first pressing portion 21B on the inner peripheral surface and the outer peripheral surface of the first pressing portion 21B is a curved line that is convex toward the axial center side. The 1st press part 21B protrudes largely in the insertion part 13 side rather than the 2nd press part 22, and the curve in the protrusion end side of the internal peripheral surface and an outer peripheral surface is the protrusion side of the 2nd press part 22 in an axial direction. The position starts from the position of the end face 24 or slightly from the main body 20 side.

The parts of the deodorization apparatus 1B shown in FIG. 3 that are not described have the same configuration as the corresponding parts in the deodorization apparatus 1, and are given the same reference numerals as in the deodorization apparatus 1 in FIG.
The deodorizing device 1B is attached to the laundry drainage inlet in the same manner as the deodorizing device 1. In the deodorization device 1B, when the wood screw penetrating the screw holes 25, 25, 25 is screwed into the floor surface, the first pressing portion 21B is pressed against the floor surface, and the first pressing portion 21B is closer to the protruding end. Since it is easily deformed, any part of its inner peripheral surface (end surface) 23B is in close contact with the floor surface. Since the screw holes 25, 25, 25 are provided at intervals of 120 degrees, even if a distribution (large or small) of the pressing force of the inner peripheral surface (end surface) 23B due to screwing of the wood screw occurs in the circumferential direction, the first pressing portion 21B Since the end surface 23B is curved, a close contact surface between the end surface 23B and the floor surface can be formed without interruption in the circumferential direction.

FIG. 4 is a diagram showing an outline of another deodorizing apparatus 1C. 4A is a plan view, and the lower half is a back view.
The deodorizing device 1 </ b> C includes a flow path forming unit 2 </ b> C and a floor surface fixing unit 3.

In the flow path forming part 2C, the hose connecting part 11C, the transition part 12C and the insertion part 13 are continuous in this order.

  11C of hose connection parts are located away from a main body in the opposite side to the side from which the 1st press part 21 grade | etc., Of the floor surface fixing | fixed part 3 protrudes. The hose connecting portion 11C is cylindrical, and its axis is slightly inclined so that the opening side is far from the main body 20 with respect to the direction (surface) in which the main body 20 in the floor surface fixing portion 3 expands. The inner diameter of the hose connecting portion 11C gradually decreases from the opening toward the back, and the inner diameter of the opening is slightly larger than the outer diameter of the discharge end of the drainage hose 72 of the washing machine.

The transition portion 12C is a cylindrical portion that is bent in an “L” shape from one end continuous to the other end of the hose coupling portion 11C. 12 C of transition parts are orthogonal to the direction (surface) in which the axial center expands at the other end.
The insertion portion 13 has a cylindrical shape with a constant inner diameter.
In the flow path forming part 2C, an internal flow path that is bent in an “L” shape is formed in the transition part 12C between the opening on the hose connecting part 11C side and the opening on the insertion part 13 side.

The attachment of the deodorizing device 1C to the laundry drainage inlet is performed in the same manner as the deodorizing device 1.
The deodorizing device 1C can prevent the odor from entering the living space from the opening of the drainage fitting, similarly to the drainage devices 1 and 1B.
FIG. 5 is a diagram showing an outline of another deodorizing apparatus 1D. The upper half of FIG. 5A is a plan view, and the lower half is a back view.

The deodorizing apparatus 1D includes a flow path forming unit 2 and a floor surface fixing unit 3D.
The flow path forming unit 2 is the same as the flow path forming unit 2 in the deodorization apparatus 1.
The floor surface fixing portion 3D includes a main body 20, a first pressing portion 21, and a plurality of ribs 29D, ..., 29D.
Consists of.
The main body 20 and the first pressing portion 21 are the same as those in the deodorization device 1.

  The rib 29D has a thick plate shape, and is orthogonal to the main body 20 on the line connecting the flow path forming portion 2 and the first pressing portion 21 at the shortest side on the side of the main body 20 where the first pressing portion 21 protrudes. Protruding. The ribs 29 </ b> D are provided at intervals of 60 degrees in the circumferential direction and extend to the vicinity of the first pressing portion 21. The degree of protrusion of the rib 29D is smaller than that of the first pressing part 21, and the difference in the degree of protrusion is larger than the thickness of the flange part 74 in the drainage fitting 71 of the drainage outlet to be attached.

Between the rib 29 </ b> D and the first pressing portion 21, a screw hole installation portion 26 that protrudes in a columnar shape from the main body 20 is provided. A screw hole 25 passes through the center of the screw hole installation portion 26.
Configurations other than the above-described portions in the deodorizing apparatus 1D are the same as those in the deodorizing apparatus 1, and the same reference numerals as those in the deodorizing apparatus 1 are given in FIG.
FIG. 6 is a diagram showing an outline of other deodorizing devices 1E to 1H.

  The deodorizing apparatus 1E shown in FIG. 6A is an inclined plane in which the protruding end surfaces 23E and 24E of the first pressing portion 21E and the second pressing portion 22E have a larger degree of protrusion on the outer side than on the inner side in the radial direction. It has become. By tilting the end surfaces 23E and 24E of the first pressing portion 21E and the second pressing portion 22E in this way, the magnitude of the pressing force to the floor surface of the first pressing portion 21E and the second pressing portion 22E by tightening the wood screws is small. Accordingly, the pressing areas of the end faces 23E and 24E change. Thereby, for example, even if there is a circumferential distribution of macro pressing force due to tightening with wood screws only in three places, even if the pressing area decreases in the weak pressing force portion, a substantial adhesion area can be secured, As a result, the adhesion between the end surfaces 23E and 24E and the floor surface can be enhanced.

  The deodorizing apparatus 1F shown in FIG. 6B has only a cylindrical first pressing portion 21F that protrudes toward the insertion portion 13 from the outer peripheral end of the circular main body 20 in the floor surface fixing portion 3F. The first pressing portion 21F is thicker than the first pressing portions 21, 21B, 21E described above that coexist with the second pressing portions 22, 22E. The end surface 23F on the protruding side of the first pressing portion 21F is an inclined plane in which the degree of protrusion on the radially outer side is larger than that on the inner side. The end face 23F of the first pressing portion 21F thus inclined has the same effect as the end faces 23E and 24E for the same reason as the end faces 23E and 24E that are inclined planes in the deodorizing device 1E.

  The deodorizing apparatus 1G shown in FIG. 6C is more easily deformed by providing an annular groove 31G having a circular cross section on the outer peripheral surface of the cylindrical first pressing portion 21E in the deodorizing apparatus 1E. It has 1 press part 21G. The protruding end surface 23G of the first pressing portion 21G is an inclined flat surface having a larger degree of protrusion on the outer side than the inner side in the radial direction, similarly to the first pressing portion 21E of the deodorizing device 1E.

The deodorizing device 1H shown in FIG. 6 (d) includes a first pressing portion 21H in which an outer circumferential surface of the first pressing portion 21 in the deodorizing device 1 is provided with an annular groove 31H having a “V” cross section, and the deodorizing device. It differs from the deodorizing device 1 only in having the second pressing portion 22H provided with an annular groove 32H having a “V” -shaped cross section on the inner peripheral surface of the second pressing portion 22 in the device 1.
The grooves 31H and 32H, when attaching the deodorization device 1H to the floor surface with a wood screw, facilitate the deformation caused by the pressing of the first pressing portion 21H and the second pressing portion 22H, respectively, and the protruding end surfaces 23 and 24 and the floor surface Promote close contact.

In the deodorizing apparatus 1H, the cross-sectional shapes of the grooves 31H and 32H may be arcuate to avoid the “V” shape where stress concentration tends to occur.

However, if at least the flange 74 of the drainage fitting 71 can be accommodated inside the second pressing part, or inside the first pressing part when it does not have the second pressing part, these planes can be used. The visual shape can be another shape, for example, a polygon or an ellipse.

Moreover, although the 1st press part 21,21B, 21E-21H and the 2nd press part 22,22E, 22H were demonstrated as cylindrical shape, these are the main bodies 20 when the deodorizing apparatus 1,1B-1H is fixed to the floor surface. As long as it surrounds the periphery of the outer end of the main body 20 that can block the insertion portion 13 side and the hose connecting portions 11 and 11C, other shapes can be adopted.
In the deodorizing devices 1 and 1B to 1H, the attachment of the deodorizing device 1 to the laundry drainage inlet is performed by the wood screw 76. In the deodorizing devices 1, 1C and 1D, the end surface 23 of the first pressing portion 21 and the second press The thing which has the part 23 may apply | coat an adhesive agent to the end surface 24, and may fix it to a floor surface.

  About the part which has an original form in each of the deodorizing apparatus 1, 1B-1H, it can employ | adopt as a corresponding part of the other deodorizing apparatuses 1, 1B-1H. For example, the rib 29D in the deodorizing device 1D can be employed in the deodorizing device 1, and the shape of the protruding end (end surface 23B, etc.) of the first pressing portion 21B in the deodorizing device 1B is employed in the first pressing portion 21 of the deodorizing device 1D. can do.

  In addition, each structure of the deodorizing apparatus 1,1B-1H and the deodorizing apparatus 1,1B-1H, or the whole structure, a shape, a dimension, a number, a material, etc. can be suitably changed along the meaning of this invention.
