The trap body has a substantially cylindrical shape with a bottom, is provided with an opening on the upper side, and is provided with a discharge port for connecting a drain pipe on the sewage side on a side surface. Further, the upper end portion inner peripheral surface is provided with a female screw and a convex portion protruding from the upper end portion in the outer peripheral direction along the peripheral edge.
The flange member has a substantially cylindrical shape, and has an outer surface provided with a male screw threadedly engaged with a female screw, and a flange portion protruding along the peripheral edge in the outer peripheral direction at the upper end portion. The flange member configured as described above forms a drain outlet inside when the construction is completed.
The sealed water bottle has a bottomed cylindrical shape and is provided with openings on the upper upper surface and the upper side surface. Moreover, this sealing water tank is comprised so that an upper part may be suspended inside a flange member at the time of construction.
The deodorizing cylinder is a substantially cylindrical member, and the upper portion has a mortar shape that increases in diameter as it goes upward. In addition, when the construction is completed, the upper end portion is connected to the drain port in a watertight manner, and the lower end portion is disposed inside the sealing tub and is disposed below the lower end of the opening on the side surface of the sealing tub.
The connecting pipe for the washing machine has an upper end connected to a washing machine drain hose that discharges waste water from the washing machine, and a lower end that is disposed inside the deodorizing cylinder, and discharges the waste water from the washing machine into the deodorizing cylinder.
The eye plate member is a member that is disposed at the drain outlet, and has an opening through which the connecting pipe for the washing machine is passed in the central part, and a plurality of holes are provided in the peripheral part to drain on the waterproof pan for the washing machine. It is configured to separate and collect hair and large garbage in the drainage when water is generated.
Of these members, the trap body and the flange member are connected and fixed to the waterproof pan for the washing machine, but other sealing bottles, deodorant tubes, connecting pipes for the washing machine, and the eye plate members are connected to the trap body. It is configured to be detachable.
The washing machine disposed on the waterproof pan for a washing machine is a drainage device (a device that generates drainage by use) that has a substantially box shape, and has an inlet for laundry on the side surface and 4 on the bottom surface. And a drain hose for a washing machine for discharging drainage containing detergent and dirt components generated by using the washing machine.

The washing machine waterproof pan and the drain trap configured as described above are constructed as follows. Although not particularly described, in the following construction, a portion requiring watertight connection is watertightly connected by screw connection using adhesion or packing as necessary.
First, an opening for arranging the trap body in the underfloor space is provided on the floor surface. Next, the outlet of the trap body is connected to the sewage side pipe through this opening. Further, the male screw portion of the flange portion is inserted into the opening of the waterproof pan for a washing machine, and then screwed into the female screw of the trap body. Thus, the trap body and the flange member are attached to the washing machine waterproof pan so that the flange lower surface of the flange member and the upper surface of the convex portion of the trap body sandwich the periphery of the opening of the waterproof pan for washing machine. Fixed.
Furthermore, a waterproof pan for a washing machine is fixed on the floor using screws or the like.
In addition, the water bottle is arranged so as to hang inside the flange member, and the deodorizing cylinder in which the washing machine connection pipe is housed is arranged so that the lower end is housed in the water bottle. The upper end is watertightly connected to the inner surface of the flange member. In this state, the opening inside the flange member functions as a drain outlet. Furthermore, after setting the eye plate member at the drain outlet and connecting the washing machine drain hose to the washing machine connection pipe, place the leg of the washing machine on the footrest, and the washing machine waterproof pan and drain The trap and the washing machine are completed.

The washing machine waterproof pan and drain trap configured as described above are used as follows.
When wastewater is generated from the washing machine using the washing machine, the wastewater from the washing machine flows into the inside of the sealed water bottle from the washing machine drain hose through the washing machine connection pipe, and accumulates sufficiently. It overflows from the opening provided on the side surface of the water seal. The waste water that has flowed out from the sealed water tank is discharged from the inside of the trap body to the sewage side through the discharge port.
In addition, if drainage occurs on the bottom surface of the waterproof pan for the washing machine due to damage to the washing machine itself or the drainage hose for the washing machine, the drainage passes through the eye plate member of the drainage port, inside the deodorizing cylinder, It passes in the order of the inside, the opening above the water bottle, the inside of the trap body, and the discharge port, and is finally discharged to the sewage side.
Further, in the drain trap configured as described above, when drainage is performed on the drain trap, the drainage collects up to the height of the lower end of the opening on the side surface inside the sealed water trough. Thereby, the part filled with the waste_water | drain is formed in the flow path from a drain outlet or a connecting pipe for washing machines to the lower end of the opening part of the side surface of a water bottle. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

By the way, the drainage from the washing machine is a drainage after washing, and various dirt components such as oil stains, hair, yarn waste, sand and the like are separated from the laundry such as clothes and removed. The detergent components used for the purpose are mixed. For this reason, these dirt adheres to the drain trap member through which such drainage passes, and each member of the drain trap becomes dirty, miscellaneous germs grow to produce a strange odor, and dirt substances accumulate, etc. This causes a problem that the drainage flow path of the water is clogged. In order to solve such a problem, the drain trap, the sealing bottle, the deodorizing cylinder, the connecting pipe for the washing machine, the eye plate member, and the like are configured to be removable from the trap body and cleaned. Yes. However, in reality, the washing machine is disposed above the waterproof pan for the washing machine, and the upper portion of the drain trap is covered with the washing machine, so that the gap between the waterproof pan for the washing machine and the washing machine becomes narrow, and the trap There was a problem that it was difficult to insert a hand to perform the removal work of the member, or it was not possible to take it out of the peripheral wall of the washing machine.
Therefore, in the waterproof pan for a washing machine and the drain trap described in Patent Document 1, the peripheral wall between the footrests has an arc shape when viewed from the side, the lower end of the washing machine placed on the footrests, The outside of the peripheral wall of the washing machine is secured by allowing a relatively large drainage trap member such as a deodorizing cylinder to lie down while ensuring a gap between the top and bottom surfaces of the peripheral wall of the machine waterproof pan. It can be taken out.
Although not specified in Patent Document 1, a screw connection is generally used to connect the trap body of the drain trap and the flange member to the waterproof pan for a washing machine. For this reason, the upper openings of the trap body and the flange member are also often formed in a circular shape in plan view in accordance with the shape of the screw. Often has a circular shape in plan view. In the case of the waterproof pan for a washing machine and the drain trap described in Patent Document 1, the peripheral wall of the portion between the footrests has an arc shape when viewed from the side, so that the sealed water bottle and the deodorizing cylinder that form a circular shape when viewed from above It is configured so that it is easy to take it down and take it out.

JP 2008-88630 A

In the case of the waterproof pan for a washing machine and the drain trap described in Patent Document 1 as described above, there are problems as described below.
In ordinary washing machine waterproof pans including the washing machine waterproof pan described in Patent Document 1, there is virtually no drainage inside the washing machine waterproof pan, such as on the inner surface or bottom surface of the peripheral wall.
This is because in a situation where the washing machine is used without any trouble, the wastewater from the washing machine flows directly into the drain trap, and the drainage does not flow inside the waterproof pan for the washing machine, particularly on the bottom surface.
If drainage flows inside the waterproof pan for washing machines, it is extremely rare that the washing machine or washing machine hose breaks down or breaks down and the drainage leaks into the waterproof pan for washing machines, or as described in paragraph 0005 As described above, when taking out the sealing water bottle at the time of cleaning, it is limited to any case where the sealing water tank is laid down and the internal drainage flows out.
The waterproof pan for washing machines is a component premised on the treatment of wastewater, and it is molded with a resin material. Unlike the case where the wastewater overflows on the normal floor surface, even if the wastewater flows into the interior, it cannot be repaired. It is possible to discharge the waste water to the sewage side without causing a problem such as a stain or damage. However, if the wastewater flows down inside the waterproof pan for a washing machine and is left as it is, a part of the wastewater stays on the passage of the wastewater, and remains so that the dirt component sticks to dryness. The nature of the dirt changes depending on the contents of the drainage, but it often contains ingredients such as hair and dirt, oil, detergent ingredients, etc., and germs grow on these dirt parts and are unsanitary, There is a problem that a strange odor is generated. As described above, the wastewater rarely flows inside the waterproof pan for a washing machine, and the wastewater hardly flows repeatedly. Therefore, the wastewater that flows later does not wash away the dirt of the previous wastewater. Accordingly, when drainage occurs inside the waterproof pan for the washing machine, it is necessary to clean the inside of the waterproof pan for the washing machine.
Of these, if the washing machine or washing machine hose breaks down or breaks down and drainage leaks into the waterproof pan for washing machine, it will be necessary to move the washing machine for repair. There is no problem in cleaning the inside of the waterproof pan for a washing machine with no obstacles above.
On the other hand, in the waterproof pan and drain trap for a washing machine described in Patent Document 1, when a drain trap member such as a sealing tub is taken out for cleaning, the washing machine is placed on the waterproof pan for the washing machine. (Originally, the invention of Patent Document 1 is an invention for taking out and cleaning the drain trap member while the washing machine is disposed above the waterproof pan for washing machine).
Normally, the inside of a waterproof pan for a washing machine is graded so that it goes down toward the opening where the drain trap is installed, but since this slope is extremely gentle, the direction of drainage flows more than the slope. Strongly influenced by how to kill. Since the method of depressing the sealing jar varies depending on the situation at that time, it depends on how the drainage inside the washing pan for the washing machine flows, and the spreading of the drainage is not stable. The inside of the waterproof pan for the washing machine is placed at a position where the floor surface is extremely low, and it is also difficult to see the inside because it is covered with the washing machine, so check the dirty part where drainage has flowed, and select only the dirty part It is difficult to clean. Therefore, in order to perform reliable cleaning, it is necessary to take a method such as cleaning the entire interior of the waterproof pan for a washing machine, regardless of whether it is dirty or not. However, the space between the lower end of the washing machine and the inside of the waterproof pan for the washing machine is narrow, and in this narrow space, insert your hand through the narrow gap between the lower end of the washing machine and the upper peripheral wall of the waterproof pan for the washing machine. Cleaning the entire inside of the waterproof pan for a washing machine is an extremely difficult task.
You can also use a hose to drain tap water, etc., inside the waterproof pan for the washing machine to wash away dirt from the drainage, but this also causes the tap water to overflow over the peripheral wall depending on the direction of the hose, etc. A suitable method because it may cause damage such as stains or damage to the floor surface outside the peripheral wall of the waterproof pan for washing machines, or it may cause tap water on the lower surface of the washing machine and cause malfunction of the washing machine. It can not be said.

When drainage occurs on the top, it is configured to separate and collect hair and large garbage in the drainage. The eye plate member 11 is formed with a notch that opens from the peripheral edge to the central opening. By utilizing the elasticity of the eye plate member 11 and expanding the notch, the connecting pipe 16 for the washing machine and the washing machine are formed. The eye plate member 11 can be taken out without releasing the connection with the water drain hose.
Of the above members, the lower end portions of the water seal 12, the deodorizing cylinder 13, and the connecting pipe 16 for the washing machine are configured to be substantially horizontal when viewed from the side. As described above, the term “horizontal” as used herein is an expression indicating that it is formed in a shape that is parallel to the side view horizontal plane in a state where construction and attachment of each member are completed. It does not indicate a “flat surface”. Strictly speaking, the lower end portion of the deodorizing cylinder 13 has a cylindrical shape and is not a “surface”, but this is a virtual flat surface formed by continuing the cylindrical lower end portion. This indicates that the surface is parallel to the side view horizontal plane in the state where the attachment of the member is completed.
Further, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, and the vertical width of the deodorizing cylinder 13 is configured to be shorter than the horizontal width of the sealed water jar 12.
The washing machine L disposed on the waterproof pan 1 for a washing machine is a drainage device (a device that generates drainage by use) that has a substantially box shape, and has a loading port for laundry on the side surface, With four legs and a washing machine drain hose (only the elbow pipe E is shown) for discharging waste water containing detergent and dirt components generated by using the washing machine L It becomes.

The washing machine waterproof pan and the drain trap configured as described above are constructed as follows. Although not particularly described, in the following construction, a portion requiring watertight connection is watertightly connected by screw connection using adhesion or packing as necessary.
First, an opening for arranging the trap body 9 is provided on the floor surface F. Next, the discharge port 9a of the trap body 9 is connected to the sewage side pipe through this opening. Further, the tubular portion 13a of the flange member 10 is inserted into the opening 2a, and the flange portion 10a of the flange member 10 is accommodated on the upper surface of the stepped portion 2b. Screw onto the female screw. Accordingly, the lower surface of the opening 2a of the waterproof pan 1 for a washing machine, that is, the bottom surface 2 of the stepped portion 2b is sandwiched between the lower surface of the flange portion 10a of the flange member 10 and the upper surface of the convex portion 9b of the trap body 9. Thus, the trap body 9 and the flange member 10 are fixed to the waterproof pan 1 for a washing machine.
Further, the waterproof pan 1 for a washing machine is fixed on the floor surface F using screws or the like.
At this time, in this embodiment, as described above, regarding the vertical positional relationship between the lower end of the back surface of the step pressing portion 2b and the lower end of the outer peripheral wall 3, the lower end of the back surface of the step pressing portion 2b is The opening provided for disposing the drainage trap T on the floor F has a width equal to or greater than the thickness of the convex portion 9b of the trap body 9 in the vertical direction. It becomes a thing which only needs to open according to the side shape except the convex part 9b of the main body 9.
Briefly, if there is a wide gap between the opening of the floor surface F and the peripheral edge of the convex portion 9b, or if the floor surface F does not exist below the convex portion 9b, ventilation in the underfloor space, etc. Leaks from the gap between the convex portions 9b, causing unnecessary ventilation on the indoor side and causing the occupant to feel uncomfortable. In order to prevent this, in the case of the conventional example, the opening of the floor surface F must be formed in a two-stage shape in which a step is provided in accordance with the opening on the side surface of the trap body 9 and the opening on the peripheral edge of the convex portion 9b. It was. However, in the first embodiment, since the convex portion 9b does not bite into the floor surface F, it is only necessary to open the floor surface F according to the side surface shape of the trap body 9, and the operation is simplified. Therefore, workability can be improved (in order to correspond to the discharge port provided on the side surface, it may be partially enlarged and expanded, and after installing the trap body, the extra opening may be blocked with a plate material. , Omitted in FIG. 1).

Next, the sealing tub 12 is disposed inside the trap body 9 so as to hang inside the flange member 10 and the mortar-shaped portion of the upper end of the deodorizing cylinder 13 housing the washing machine connection pipe 16 therein. The outer peripheral portion is watertightly connected to the inner surface of the flange member 10.
As a result, the connecting pipe 16 for the washing machine is in a state in which the T-shape is turned upside down, and the ends of the horizontal tube part are slightly outside the outer surface of the cylinder part 13a of the deodorizing cylinder 13 at both ends. Can be attached to the inside of the drain trap T.
In this state, the opening inside the flange member 10 functions as the drain port 10b. Further, the eye plate member 11 is set in the drain port 10b, and the washing machine drain hose is connected to the washing machine connection pipe 16 by using the elbow pipe E or the like. Place. Finally, the wall member 8 is watertightly attached to the recess 5 to complete the construction of the waterproof pan for the washing machine, the drain trap, and the washing machine.

The washing machine waterproof pan and drain trap configured as described above are used as follows.
When the washing machine L is used and drainage is generated from the washing machine L, the drainage from the washing machine L flows from the washing machine drain hose through the washing machine connection pipe 16 into the sealed water bottle 12 and accumulates. When it is sufficiently collected, it overflows from the opening provided on the side surface of the sealing tub 12. The waste water that has flowed out of the sealing tub 12 is discharged from the inside of the trap body 9 to the sewage side through the discharge port 9a. At this time, since the ends of the horizontal tube portion of the connecting pipe 16 for the washing machine are configured so that both ends protrude slightly outward from the outer surface of the tube portion 13a of the deodorizing tube 13, the washing machine The bubble-mixed waste water from L is first discharged only to the outside of the cylindrical portion 13 a of the deodorizing cylinder 13 and is not discharged to the inside of the deodorizing cylinder 13. Since the bubbles in the drainage are lifted with respect to the drainage by the buoyancy, the bubbles in the drainage discharged to the outside of the cylindrical portion 13a of the deodorizing cylinder 13 are directly between the outer surface of the deodorizing cylinder 13 and the inner surface of the sealing tub 12. And is discharged downstream from the opening on the side surface of the sealing tub 12 and does not flow backward from the inner surface of the deodorizing cylinder 13 to the drain port 10b.
Further, if drainage occurs on the bottom surface 2 of the washing machine waterproof pan 1 due to damage to the washing machine L itself or the washing machine drain hose, etc., the drainage is at least the bottom surface 2 of the step portion 6 of the washing machine waterproof pan 1. After passing through the top, it passes through the eye plate member 11 of the drainage port 10b, and in the order of the inside of the deodorizing cylinder 13, the inside of the sealing tub 12, the opening above the sealing tub 12, the inside of the trap body 9, and the discharge port 9a. Passes through and is finally discharged to the sewage side.
In addition, since the wall member 8 is watertightly attached to the recess 5 of the peripheral wall 3, even if drainage occurs inside the waterproof pan 1 for a washing machine, as long as the drainage does not accumulate at the upper end of the peripheral wall 3, Does not overflow from the inside of the waterproof pan 1 for a washing machine.
Further, in the drain trap T configured as described above, when drainage is performed in the drain trap T via the washing machine connection pipe 16 or the drain port 10b, the bottom end of the side opening is placed inside the sealing tub 12. Drainage collects up to the height. Thus, a portion filled with drainage is formed in the flow path from the drain outlet 10b or the connecting pipe 16 for the washing machine to the lower end of the opening 2a on the side surface of the sealing tub 12. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

In the waterproof pan and drainage trap for the washing machine of the first embodiment configured as described above, due to long-term use, dirt adheres to the inside of the drainage trap T, and a strange odor is produced, such as accumulated hair and lint. When pipe clogging occurs due to dust, dirt components, etc., and it becomes necessary to clean the inside of the drain trap T, the member of the drain trap T can be taken out and cleaned by the following method.
First, the wall member 8 is removed from the recess 5 to secure a clearance space in which the operator's hand can be inserted into the peripheral wall 3.
Next, the diameter of the notch is expanded, the eye plate member 11 is removed from the washing machine connecting pipe 16 or the washing machine drain hose, and taken out to the outside of the peripheral wall 3 through the step 6 and the recess 5.
Next, the connection between the washing machine connection pipe 16 and the washing machine drain hose is released, and then the connection between the deodorizing cylinder 13 and the flange member 10 is released.
Thereafter, the deodorizing cylinder 13, the washing machine connection pipe 16, and the water seal 12 are taken out of the peripheral wall 3.
When the member of the drain trap T is taken out, the cleaning operator takes the following reasons when taking out the members such as the deodorizing cylinder 13 and the water seal 12. To reason 3 For this reason, the deodorizing cylinder 13 and the water seal 12 are taken out from the opening 2a at the bottom (in the case of this embodiment, the drain port 10b inside the flange member 10) and moved horizontally without being inclined. Thus, as shown in FIG. Therefore, it is almost certainly eliminated that the sealed water (drainage) in the sealed water bottle 12 is spilled on the bottom surface 2 other than the step portion 6.
Reason 1. In this embodiment, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, and the vertical width of the deodorizing cylinder 13 is configured to be shorter than the horizontal width of the sealed water jar 12, As in the conventional example, there is no merit in inclining the sealed water bottle 12 or the deodorizing cylinder 13 (especially the sealed water bottle 12), and it is preferable to move it horizontally without being inclined and take it out from the peripheral wall 3. Consists of.
Reason 2 In the cleaning operation, the step portion 6 functions as a guide, and has an effect of preventing members such as the deodorizing cylinder 13 and the water seal 12 from being inclined in the lateral direction.
Reason 3. The bottom ends of the water seal 12, the deodorizing cylinder 13, and the recess 5 are configured to be substantially horizontal when viewed from the side. Thereby, when taking out the sealing water bottle 12 and the deodorizing cylinder 13 from the recessed part 5, it functions as a guide which takes out the sealing water bottle 12 and the deodorizing cylinder 13 without inclining, and members, such as the deodorizing cylinder 13 and the sealing water bottle 12, are sideways. There is an effect of preventing tilting in the direction.

  Furthermore, in this embodiment, the bottom surface 2 other than the step portion 6 is made smaller by making the height width from the bottom surface 2 other than the step portion 6 to the upper end of the footrest 4 smaller than the height width of the sealing jar 12 and the deodorizing cylinder 13. It is impossible to move the water seal 12 and the deodorizing cylinder 13 upward. Thereby, it is surely prevented that the sealed water (drainage) in the sealed water bottle 12 is spilled on the bottom surface 2 other than the step portion 6. Even if the spilled water is spilled, the sealed water is spilled only on the stepped portion 6 communicating with the recessed portion 5, so that the portion that needs to be cleaned is easily visible and the operator can easily insert the hand into the recessed portion 5. And it is limited only to the step part 6, and cleaning is very easy.

After removing the member from the drain trap T and cleaning it in this way, in some cases, cleaning the inside of the trap body 9 or cleaning the pipe downstream from the discharge port 9a / resolving clogging of the equipment, etc. After carrying out the work through the recess 5 and the drain port 10b to perform the cleaning work / clogging of the tube, the work other than placing the washing machine L on the waterproof pan 1 for the washing machine described in paragraph 0021 is performed. By repeating, the attachment operation | work of the member of the drain trap T is completed, and the cleaning operation | work of the drain trap T is completed.

When it is sufficiently collected, it overflows from the opening provided on the side surface of the sealing tub 12. The waste water that has flowed out of the sealing tub 12 is discharged from the inside of the trap body 9 to the sewage side through the discharge port 9a. At this time, since the ends of the horizontal tube portion of the connecting pipe 16 for the washing machine are configured so that both ends protrude slightly outward from the outer surface of the tube portion 13a of the deodorizing tube 13, the washing machine The bubble-mixed waste water from L is first discharged only to the outside of the cylindrical portion 13 a of the deodorizing cylinder 13 and is not discharged to the inside of the deodorizing cylinder 13. Since the bubbles in the drainage are lifted with respect to the drainage by the buoyancy, the bubbles in the drainage discharged to the outside of the cylindrical portion 13a of the deodorizing cylinder 13 are directly between the outer surface of the deodorizing cylinder 13 and the inner surface of the sealing tub 12. And is discharged downstream from the opening on the side surface of the sealing tub 12 and does not flow backward from the inner surface of the deodorizing cylinder 13 to the drain port 10b.
Further, when drainage occurs on the bottom surface 2 of the washing machine waterproof pan 1 due to damage to the washing machine L itself or the washing machine drain hose, the drainage passes over the bottom surface 2 of the washing machine waterproof pan 1. Then, it passes through the eye plate member 11 of the drain port 10b, passes in the order of the inside of the deodorizing cylinder 13, the inside of the sealed water bottle 12, the opening above the sealed water bottle 12, the inside of the trap body 9 and the discharge port 9a. Discharged to the sewage side.
In addition, since the wall member 8 is watertightly attached to the recess 5 of the peripheral wall 3, even if drainage occurs inside the waterproof pan 1 for a washing machine, as long as the drainage does not accumulate at the upper end of the peripheral wall 3, Does not overflow from the inside of the waterproof pan 1 for a washing machine.
Further, in the drain trap T configured as described above, when drainage is performed in the drain trap T via the washing machine connection pipe 16 or the drain port 10b, the bottom end of the side opening is placed inside the sealing tub 12. Drainage collects up to the height. Thus, a portion filled with drainage is formed in the flow path from the drain outlet 10b or the connecting pipe 16 for the washing machine to the lower end of the opening 2a on the side surface of the sealing tub 12. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

In the waterproof pan and drainage trap for the washing machine of the second embodiment configured as described above, due to long-term use, dirt adheres to the inside of the drainage trap T, and a strange odor is produced, such as accumulated hair and lint. When pipe clogging occurs due to dust, dirt components, etc., and it becomes necessary to clean the inside of the drain trap T, the member of the drain trap T can be taken out and cleaned by the following method.
First, the wall member 8 is removed from the recess 5 to secure a clearance space in which the operator's hand can be inserted into the peripheral wall 3.
Next, the diameter of the notch is expanded, the eye plate member 11 is removed from the washing machine connecting pipe 16 or the washing machine drain hose, and taken out to the outside of the peripheral wall 3 through the step 6 and the recess 5.
Next, the connection between the washing machine connection pipe 16 and the washing machine drain hose is released, and then the connection between the deodorizing cylinder 13 and the flange member 10 is released.
Thereafter, the sealing unit with connection pipe 15 is taken out of the peripheral wall 3.
When the member of the drain trap T is taken out, the cleaning operator takes the reason described below when taking out the sealing unit 15 with a connecting pipe. To reason 6 For this reason, the sealing unit with connection pipe 15 is taken out from the opening 2a at the bottom (in the case of the present embodiment, the drain port 10b inside the flange member 10), and is tilted as it is as shown in FIG. It is moved horizontally without taking out from the recess 5. Therefore, the sealed water (drainage) in the sealed water tub 12 is almost certainly not spilled on the bottom surface 2.
Reason 4 In the present embodiment, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, the vertical width of the deodorizing cylinder 13 is shorter than the horizontal width of the sealed water jar 12, and the sealed water unit 14 is also drained. The vertical width of the unit is configured to be shorter than the horizontal width of the drainage unit (in the state of the sealing unit 15 with connecting pipe, the vertical width and the horizontal width are substantially the same, and the vertical width is slightly shorter).
For this reason, there is no merit in inclining the sealed water bottle 12 or the deodorizing cylinder 13 (especially the sealed water bottle 12) as in the conventional example, and it is preferable to move it horizontally without taking it out and to take it out from the peripheral wall 3. It is comprised so that.
Reason 5. The bottom end of each of the water seal 12, the deodorizing cylinder 13, and the recess 5, particularly the bottom end of the water seal 12 that is the lower end of the water seal unit 15 with a connecting pipe is configured to be substantially horizontal when viewed from the side. Become. Thus, when the sealing unit with connection pipe 15 is taken out from the recess 5, it functions as a guide for taking out the sealing unit with connection pipe 15 without tilting, and the deodorizing cylinder 13 constituting the sealing unit with connection pipe 15, sealing There exists an effect which prevents that members, such as the water tank 12, incline to a horizontal direction.
Reason 6 In the sealing unit 15 with connecting pipe, when the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and pulled up as it is, the deodorizing cylinders are attached to both ends of the horizontal pipe portion of the connecting pipe 16 for the washing machine. Since the deodorizing cylinder 13 and the sealing tub 12 are engaged by the claw portion 13b, the members of the sealing unit with a connecting pipe 15 are maintained in a horizontal state. Can be pulled up easily. At this time, the connection of the deodorizing cylinder 13, the water seal 12 and the connecting pipe 16 for the washing machine is not fixed and is merely an engagement degree with mounting and play. Even if the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and tilted, the sealing water of the sealing tub 12 acts like a weight and cannot be tilted as desired by the operator.
As a result, when the cleaning operator moves the sealing unit 14, the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and maintained in a horizontal state without tilting the sealing unit 14. Will be moved.

After removing the member from the drain trap T and cleaning it in this way, in some cases, cleaning the inside of the trap body 9 or cleaning the pipe downstream from the discharge port 9a / resolving clogging of the equipment, etc. After performing the work through the recess 5 and the drain port 10b to perform cleaning work / clogging of the pipe, work other than placing the washing machine L on the waterproof pan 1 for the washing machine described in paragraph 0028 is performed. By repeating, the attachment operation | work of the member of the drain trap T is completed, and the cleaning operation | work of the drain trap T is completed.

The embodiments of the present invention are as described above. However, the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention.
For example, in the second embodiment, the drainage trap T that becomes the sealing unit 14 by engaging the sealing jar 12 and the deodorizing cylinder 13 with the waterproof pan 1 for a washing machine that does not have the stepped portion 6 is adopted. However, the present invention is not limited to the above embodiment, and the drain trap T in which the sealing tub 12 and the deodorizing cylinder 13 are not engaged with the waterproof pan 1 for a washing machine not having the stepped portion 6. May be adopted. Even in this case, Reason 1. Reason 2 (Or Reason 4. and Reason 5.), when the member of the drain trap T is taken out, the worker of the cleaning work takes out the deodorizing cylinder 13 from the opening 2a at the bottom when taking out the sealing unit 15 with the connecting pipe. Then, the member of the drain trap T such as the sealing tub 12 is taken out upward, moved as it is without being inclined, and taken out from the recess 5. Therefore, the sealed water (drainage) in the sealed water tub 12 is almost certainly not spilled on the bottom surface 2.

  The present invention relates to a drain trap and a waterproof pan for a washing machine, and more particularly, a washing machine having good cleaning properties for a waterproof pan for a washing machine and a drain trap member attached to the waterproof pan for the washing machine. The present invention relates to a waterproof pan and a drain trap.

Conventionally, a waterproof pan for a washing machine on which the washing machine is placed, and a wastewater generated on the waterproof pan for the washing machine and a drain on the washing machine placed on the washing machine are attached to the waterproof pan for the washing machine. Drain traps are well known. As an example, a waterproof pan for a washing machine and a drain trap described in Patent Document 1 will be described.
The conventional waterproof pan for a washing machine described in Patent Document 1 and the drain trap attached to the waterproof pan for the washing machine are composed of the waterproof pan for a washing machine described below and a drain trap. It is used for the washing machine described in 1.
A waterproof pan for a washing machine has a square shape in plan view, and includes a bottom surface having an opening, a footrest provided at four corners of the bottom surface, and a peripheral wall erected upward from the periphery of the bottom surface. It becomes. A part of the peripheral wall is formed integrally with the footrest.
Furthermore, the wall surface of the peripheral wall between the footrests is configured to form an arc that is convex downward in a side view.
The drain trap is composed of a trap body, a flange member, a water seal, a deodorizing cylinder, a connecting pipe for a washing machine, and an eye plate member described below.
The trap body has a substantially cylindrical shape with a bottom, is provided with an opening on the upper side, and is provided with a discharge port for connecting a drain pipe on the sewage side on a side surface. Further, the upper end portion inner peripheral surface is provided with a female screw and a convex portion protruding from the upper end portion in the outer peripheral direction along the peripheral edge.
The flange member has a substantially cylindrical shape, and has an outer surface provided with a male screw threadedly engaged with a female screw, and a flange portion protruding along the peripheral edge in the outer peripheral direction at the upper end portion. The flange member configured as described above forms a drain outlet inside when the construction is completed.
The sealed water bottle has a bottomed cylindrical shape and is provided with openings on the upper upper surface and the upper side surface. Moreover, this sealing water tank is comprised so that an upper part may be suspended inside a flange member at the time of construction.
The deodorizing cylinder is a substantially cylindrical member, and the upper portion has a mortar shape that increases in diameter as it goes upward. In addition, when the construction is completed, the upper end portion is connected to the drain port in a watertight manner, and the lower end portion is disposed inside the sealing tub and is disposed below the lower end of the opening on the side surface of the sealing tub.
The connecting pipe for the washing machine has an upper end connected to a washing machine drain hose that discharges waste water from the washing machine, and a lower end that is disposed inside the deodorizing cylinder, and discharges the waste water from the washing machine into the deodorizing cylinder.
The eye plate member is a member that is disposed at the drain outlet, and has an opening through which the connecting pipe for the washing machine is passed in the central part, and a plurality of holes are provided in the peripheral part to drain on the waterproof pan for the washing machine. It is configured to separate and collect hair and large garbage in the drainage when water is generated.
Of these members, the trap body and the flange member are connected and fixed to the waterproof pan for the washing machine, but other sealing bottles, deodorant tubes, connecting pipes for the washing machine, and the eye plate members are connected to the trap body. It is configured to be detachable.
The washing machine disposed on the waterproof pan for a washing machine is a drainage device (a device that generates drainage by use) that has a substantially box shape, and has an inlet for laundry on the side surface and 4 on the bottom surface. And a drain hose for a washing machine for discharging drainage containing detergent and dirt components generated by using the washing machine.

The washing machine waterproof pan and the drain trap configured as described above are constructed as follows. Although not particularly described, in the following construction, a portion requiring watertight connection is watertightly connected by screw connection using adhesion or packing as necessary.
First, an opening for arranging the trap body in the underfloor space is provided on the floor surface. Next, the outlet of the trap body is connected to the sewage side pipe through this opening. Further, the male screw portion of the flange portion is inserted into the opening of the waterproof pan for a washing machine, and then screwed into the female screw of the trap body. Thus, the trap body and the flange member are attached to the washing machine waterproof pan so that the flange lower surface of the flange member and the upper surface of the convex portion of the trap body sandwich the periphery of the opening of the waterproof pan for washing machine. Fixed.
Furthermore, a waterproof pan for a washing machine is fixed on the floor using screws or the like.
In addition, the water bottle is arranged so as to hang inside the flange member, and the deodorizing cylinder in which the washing machine connection pipe is housed is arranged so that the lower end is housed in the water bottle. The upper end is watertightly connected to the inner surface of the flange member. In this state, the opening inside the flange member functions as a drain outlet. Furthermore, after setting the eye plate member at the drain outlet and connecting the washing machine drain hose to the washing machine connection pipe, place the leg of the washing machine on the footrest, and the washing machine waterproof pan and drain The trap and the washing machine are completed.

The washing machine waterproof pan and drain trap configured as described above are used as follows.
When wastewater is generated from the washing machine using the washing machine, the wastewater from the washing machine flows into the inside of the sealed water bottle from the washing machine drain hose through the washing machine connection pipe, and accumulates sufficiently. It overflows from the opening provided on the side surface of the water seal. The waste water that has flowed out from the sealed water tank is discharged from the inside of the trap body to the sewage side through the discharge port.
In addition, if drainage occurs on the bottom surface of the waterproof pan for the washing machine due to damage to the washing machine itself or the drainage hose for the washing machine, the drainage passes through the eye plate member of the drainage port, inside the deodorizing cylinder, It passes in the order of the inside, the opening above the water bottle, the inside of the trap body, and the discharge port, and is finally discharged to the sewage side.
Further, in the drain trap configured as described above, when drainage is performed on the drain trap, the drainage collects up to the height of the lower end of the opening on the side surface inside the sealed water trough. Thereby, the part filled with the waste_water | drain is formed in the flow path from a drain outlet or a connecting pipe for washing machines to the lower end of the opening part of the side surface of a water bottle. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

By the way, the drainage from the washing machine is a drainage after washing, and various dirt components such as oil stains, hair, yarn waste, sand and the like are separated from the laundry such as clothes and removed. The detergent components used for the purpose are mixed. For this reason, these dirt adheres to the drain trap member through which such drainage passes, and each member of the drain trap becomes dirty, miscellaneous germs grow to produce a strange odor, and dirt substances accumulate, etc. This causes a problem that the drainage flow path of the water is clogged. In order to solve such a problem, the drain trap, the sealing bottle, the deodorizing cylinder, the connecting pipe for the washing machine, the eye plate member, and the like are configured to be removable from the trap body and cleaned. Yes. However, in reality, the washing machine is disposed above the waterproof pan for the washing machine, and the upper portion of the drain trap is covered with the washing machine, so that the gap between the waterproof pan for the washing machine and the washing machine becomes narrow, and the trap There was a problem that it was difficult to insert a hand to perform the removal work of the member, or it was not possible to take it out of the peripheral wall of the washing machine.
Therefore, in the waterproof pan for a washing machine and the drain trap described in Patent Document 1, the peripheral wall between the footrests has an arc shape when viewed from the side, the lower end of the washing machine placed on the footrests, The outside of the peripheral wall of the washing machine is secured by allowing a relatively large drainage trap member such as a deodorizing cylinder to lie down while ensuring a gap between the top and bottom surfaces of the peripheral wall of the machine waterproof pan. It can be taken out.
Although not specified in Patent Document 1, a screw connection is generally used to connect the trap body of the drain trap and the flange member to the waterproof pan for a washing machine. For this reason, the upper openings of the trap body and the flange member are also often formed in a circular shape in plan view in accordance with the shape of the screw. Often has a circular shape in plan view. In the case of the waterproof pan for a washing machine and the drain trap described in Patent Document 1, the peripheral wall of the portion between the footrests has an arc shape when viewed from the side, so that the sealed water bottle and the deodorizing cylinder that form a circular shape when viewed from above It is configured so that it is easy to take it down and take it out.

JP 2008-88630 A

In the case of the waterproof pan for a washing machine and the drain trap described in Patent Document 1 as described above, there are problems as described below.
In ordinary washing machine waterproof pans including the washing machine waterproof pan described in Patent Document 1, there is virtually no drainage inside the washing machine waterproof pan, such as on the inner surface or bottom surface of the peripheral wall.
This is because in a situation where the washing machine is used without any trouble, the wastewater from the washing machine flows directly into the drain trap, and the drainage does not flow inside the waterproof pan for the washing machine, particularly on the bottom surface.
If drainage flows inside the waterproof pan for washing machines, it is extremely rare that the washing machine or washing machine hose breaks down or breaks down and the drainage leaks into the waterproof pan for washing machines, or as described in paragraph 0005 As described above, when taking out the sealing water bottle at the time of cleaning, it is limited to any case where the sealing water tank is laid down and the internal drainage flows out.
The waterproof pan for washing machines is a component premised on the treatment of wastewater, and it is molded with a resin material. Unlike the case where the wastewater overflows on the normal floor surface, even if the wastewater flows into the interior, it cannot be repaired. It is possible to discharge the waste water to the sewage side without causing a problem such as a stain or damage. However, if the wastewater flows down inside the waterproof pan for a washing machine and is left as it is, a part of the wastewater stays on the passage of the wastewater, and remains so that the dirt component sticks to dryness. The nature of the dirt changes depending on the contents of the drainage, but it often contains ingredients such as hair and dirt, oil, detergent ingredients, etc., and germs grow on these dirt parts and are unsanitary, There is a problem that a strange odor is generated. As described above, the wastewater rarely flows inside the waterproof pan for a washing machine, and the wastewater hardly flows repeatedly. Therefore, the wastewater that flows later does not wash away the dirt of the previous wastewater. Accordingly, when drainage occurs inside the waterproof pan for the washing machine, it is necessary to clean the inside of the waterproof pan for the washing machine.
Of these, if the washing machine or washing machine hose breaks down or breaks down and drainage leaks into the waterproof pan for washing machine, it will be necessary to move the washing machine for repair. There is no problem in cleaning the inside of the waterproof pan for a washing machine with no obstacles above.
On the other hand, in the waterproof pan and drain trap for a washing machine described in Patent Document 1, when a drain trap member such as a sealing tub is taken out for cleaning, the washing machine is placed on the waterproof pan for the washing machine. (Originally, the invention of Patent Document 1 is an invention for taking out and cleaning the drain trap member while the washing machine is disposed above the waterproof pan for washing machine).
Normally, the inside of a waterproof pan for a washing machine is graded so that it goes down toward the opening where the drain trap is installed, but since this slope is extremely gentle, the direction of drainage flows more than the slope. Strongly influenced by how to kill. Since the method of depressing the sealing jar varies depending on the situation at that time, it depends on how the drainage inside the washing pan for the washing machine flows, and the spreading of the drainage is not stable. The inside of the waterproof pan for the washing machine is placed at a position where the floor surface is extremely low, and it is also difficult to see the inside because it is covered with the washing machine, so check the dirty part where drainage has flowed, and select only the dirty part It is difficult to clean. Therefore, in order to perform reliable cleaning, it is necessary to take a method such as cleaning the entire interior of the waterproof pan for a washing machine, regardless of whether it is dirty or not. However, the space between the lower end of the washing machine and the inside of the waterproof pan for the washing machine is narrow, and in this narrow space, insert your hand through the narrow gap between the lower end of the washing machine and the upper peripheral wall of the waterproof pan for the washing machine. Cleaning the entire inside of the waterproof pan for a washing machine is an extremely difficult task.
You can also use a hose to drain tap water, etc., inside the waterproof pan for the washing machine to wash away dirt from the drainage, but this also causes the tap water to overflow over the peripheral wall depending on the direction of the hose, etc. A suitable method because it may cause damage such as stains or damage to the floor surface outside the peripheral wall of the waterproof pan for washing machines, or it may cause tap water on the lower surface of the washing machine and cause malfunction of the washing machine. It can not be said.

Moreover, the height width from the bottom face 2 of the recessed part 5 and the bottom face 2 of the step part 6 to the upper end of the footrest 4 is wider than the vertical width of the sealing tub 12 and the deodorizing cylinder 13 of the drain trap T described later. In addition, the height width H2 from the bottom surface 2 other than the step portion 6 to the upper end of the footrest 4 is configured so as to be narrower than the vertical width of the sealing jar 12 and the deodorizing cylinder 13.
Further, the bottom surface 2 other than the step portion 6 and the bottom surface 2 of the step portion 6 are connected to each other by a side wall of the step portion 6 that is substantially suspended, and the side wall of the step portion 6 is connected to the wall surface of the side surface of the recess 5. While forming the return portion 7 which is a wall surface slightly inward from the side surface, the connection is made continuously.
The wall member 8 is a substantially plate-like member that is attached to the recess 5 of the waterproof pan 1 for a washing machine in a watertight and detachable manner. The outer side surface and the upper end of the peripheral wall 3 around the recess 5 are the peripheral wall 3. It is attached so as to be continuous.
Except for the wall member 8 (and a fixing screw member and a packing for watertight connection), the waterproof pan 1 for a washing machine is molded as an integral member with a resin material such as FRP.
The drainage trap T includes the trap body 9, the flange member 10, the water seal 12, the deodorizing cylinder 13, the washing machine connection pipe 16, and the eye plate member 11 described below.
The trap body 9 has a substantially cylindrical shape with a bottom, is provided with an opening at the top, and a discharge port 9a for connecting a drain pipe on the sewage side to the side surface. The upper end portion inner peripheral surface is provided with a female screw and a convex portion 9b protruding from the upper end portion in the outer peripheral direction along the peripheral edge.
The flange member 10 has a substantially cylindrical shape, and has an outer surface provided with a male screw threadedly engaged with a female screw of the trap body 9 and a flange portion 10a protruding along the peripheral edge in the outer peripheral direction at the upper end portion. . The flange member 10 configured as described above forms a drain port 10b when the construction is completed.
The water seal 12 has a bottomed cylindrical shape and is provided with openings on the upper upper surface and the upper side surface. Moreover, this sealing water tank 12 is comprised so that an upper part may be suspended inside the flange member 10 at the time of construction.
The deodorizing cylinder 13 is a substantially cylindrical member, and the upper portion is configured to have a mortar shape that increases in diameter as it goes upward. Further, when the construction is completed, the upper end portion is connected to the drain port 10b in a watertight manner, and the lower end portion is disposed inside the sealing tub 12 and below the lower end of the opening on the side surface of the sealing tub 12. .
The connecting pipe 16 for the washing machine is a tubular body branched into a substantially T-shape, and the vertical tubular body portion is placed inside the tubular body portion 13a of the deodorizing cylinder 13 with the T-shape turned upside down during construction. The horizontal tube portion is disposed between the lower end of the deodorizing cylinder 13 and the upper surface of the lower wall of the sealing tub 12 (the horizontal tube portion is shaped flat). Moreover, the end part of a horizontal pipe part is comprised so that it may protrude a little outside rather than the outer surface of the cylinder part 13a of the deodorizing cylinder 13 in both ends. At the time of construction, the upper end of the central vertical pipe body of the connecting pipe 16 for the washing machine configured as described above is connected to a drain hose for the washing machine that discharges drainage from the washing machine, and drains from the washing machine. Is discharged to the outside of the deodorizing cylinder 13 and inside the sealed water bottle 12.
The eye plate member 11 is a member disposed in the drainage port 10b, and has an opening through which the washing machine connection pipe 16 is passed in the central portion and a plurality of holes in the peripheral portion so that the waterproof pan 1 for the washing machine is provided. When drainage occurs on the top, it is configured to separate and collect hair and large garbage in the drainage. The eye plate member 11 is formed with a notch that opens from the peripheral edge to the central opening. By utilizing the elasticity of the eye plate member 11 and expanding the notch, the connecting pipe 16 for the washing machine and the washing machine are formed. The eye plate member 11 can be taken out without releasing the connection with the water drain hose.
Of the above members, the lower end portions of the water seal 12, the deodorizing cylinder 13, and the connecting pipe 16 for the washing machine are configured to be substantially horizontal when viewed from the side. As described above, the term “horizontal” as used herein is an expression indicating that it is formed in a shape that is parallel to the side view horizontal plane in a state where construction and attachment of each member are completed. It does not indicate a “flat surface”. Strictly speaking, the lower end portion of the deodorizing cylinder 13 has a cylindrical shape and is not a “surface”, but this is a virtual flat surface formed by continuing the cylindrical lower end portion. This indicates that the surface is parallel to the side view horizontal plane in the state where the attachment of the member is completed.
Further, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, and the vertical width of the deodorizing cylinder 13 is configured to be shorter than the horizontal width of the sealed water jar 12.
The washing machine L disposed on the waterproof pan 1 for a washing machine is a drainage device (a device that generates drainage by use) that has a substantially box shape, and has a loading port for laundry on the side surface, With four legs and a washing machine drain hose (only the elbow pipe E is shown) for discharging waste water containing detergent and dirt components generated by using the washing machine L It becomes.

The washing machine waterproof pan and the drain trap configured as described above are constructed as follows. Although not particularly described, in the following construction, a portion requiring watertight connection is watertightly connected by screw connection using adhesion or packing as necessary.
First, an opening for arranging the trap body 9 is provided on the floor surface F. Next, the discharge port 9a of the trap body 9 is connected to the sewage side pipe through this opening. Further, the tubular portion 13a of the flange member 10 is inserted into the opening 2a, and the flange portion 10a of the flange member 10 is accommodated on the upper surface of the stepped portion 2b. Screw onto the female screw. Accordingly, the lower surface of the opening 2a of the waterproof pan 1 for a washing machine, that is, the bottom surface 2 of the stepped portion 2b is sandwiched between the lower surface of the flange portion 10a of the flange member 10 and the upper surface of the convex portion 9b of the trap body 9. Thus, the trap body 9 and the flange member 10 are fixed to the waterproof pan 1 for a washing machine.
Further, the waterproof pan 1 for a washing machine is fixed on the floor surface F using screws or the like.
At this time, in this embodiment, as described above, regarding the vertical positional relationship between the lower end of the back surface of the step pressing portion 2b and the lower end of the outer peripheral wall 3, the lower end of the back surface of the step pressing portion 2b is The opening provided for disposing the drainage trap T on the floor F has a width equal to or greater than the thickness of the convex portion 9b of the trap body 9 in the vertical direction. It becomes a thing which only needs to open according to the side shape except the convex part 9b of the main body 9.
Briefly, if there is a wide gap between the opening of the floor surface F and the peripheral edge of the convex portion 9b, or if the floor surface F does not exist below the convex portion 9b, ventilation in the underfloor space, etc. Leaks from the gap between the convex portions 9b, causing unnecessary ventilation on the indoor side and causing the occupant to feel uncomfortable. In order to prevent this, in the case of the conventional example, the opening of the floor surface F must be formed in a two-stage shape in which a step is provided in accordance with the opening on the side surface of the trap body 9 and the opening on the peripheral edge of the convex portion 9b. It was. However, in the first embodiment, since the convex portion 9b does not bite into the floor surface F, it is only necessary to open the floor surface F according to the side surface shape of the trap body 9, and the operation is simplified. Therefore, workability can be improved (in order to correspond to the discharge port provided on the side surface, it may be partially enlarged and expanded, and after installing the trap body, the extra opening may be blocked with a plate material. , Omitted in FIG. 1).

Next, the sealing tub 12 is disposed inside the trap body 9 so as to hang inside the flange member 10 and the mortar-shaped portion of the upper end of the deodorizing cylinder 13 housing the washing machine connection pipe 16 therein. The outer peripheral portion is watertightly connected to the inner surface of the flange member 10.
As a result, the connecting pipe 16 for the washing machine is in a state in which the T-shape is turned upside down, and the ends of the horizontal tube part are slightly outside the outer surface of the cylinder part 13a of the deodorizing cylinder 13 at both ends. Can be attached to the inside of the drain trap T.
In this state, the opening inside the flange member 10 functions as the drain port 10b. Further, the eye plate member 11 is set in the drain port 10b, and the washing machine drain hose is connected to the washing machine connection pipe 16 by using the elbow pipe E or the like. Place. Finally, the wall member 8 is watertightly attached to the recess 5 to complete the construction of the waterproof pan for the washing machine, the drain trap, and the washing machine.

The washing machine waterproof pan and drain trap configured as described above are used as follows.
When the washing machine L is used and drainage is generated from the washing machine L, the drainage from the washing machine L flows from the washing machine drain hose through the washing machine connection pipe 16 into the sealed water bottle 12 and accumulates. When it is sufficiently collected, it overflows from the opening provided on the side surface of the sealing tub 12. The waste water that has flowed out of the sealing tub 12 is discharged from the inside of the trap body 9 to the sewage side through the discharge port 9a. At this time, since the ends of the horizontal tube portion of the connecting pipe 16 for the washing machine are configured so that both ends protrude slightly outward from the outer surface of the tube portion 13a of the deodorizing tube 13, the washing machine The bubble-mixed waste water from L is first discharged only to the outside of the cylindrical portion 13 a of the deodorizing cylinder 13 and is not discharged to the inside of the deodorizing cylinder 13. Since the bubbles in the drainage are lifted with respect to the drainage by the buoyancy, the bubbles in the drainage discharged to the outside of the cylindrical portion 13a of the deodorizing cylinder 13 are directly between the outer surface of the deodorizing cylinder 13 and the inner surface of the sealing tub 12. And is discharged downstream from the opening on the side surface of the sealing tub 12 and does not flow backward from the inner surface of the deodorizing cylinder 13 to the drain port 10b.
Further, if drainage occurs on the bottom surface 2 of the washing machine waterproof pan 1 due to damage to the washing machine L itself or the washing machine drain hose, etc., the drainage is at least the bottom surface 2 of the step portion 6 of the washing machine waterproof pan 1. After passing through the top, it passes through the eye plate member 11 of the drainage port 10b, and in the order of the inside of the deodorizing cylinder 13, the inside of the sealing tub 12, the opening above the sealing tub 12, the inside of the trap body 9, and the discharge port 9a. Passes through and is finally discharged to the sewage side.
In addition, since the wall member 8 is watertightly attached to the recess 5 of the peripheral wall 3, even if drainage occurs inside the waterproof pan 1 for a washing machine, as long as the drainage does not accumulate at the upper end of the peripheral wall 3, Does not overflow from the inside of the waterproof pan 1 for a washing machine.
Further, in the drain trap T configured as described above, when drainage is performed in the drain trap T via the washing machine connection pipe 16 or the drain port 10b, the bottom end of the side opening is placed inside the sealing tub 12. Drainage collects up to the height. Thus, a portion filled with drainage is formed in the flow path from the drain outlet 10b or the connecting pipe 16 for the washing machine to the lower end of the opening 2a on the side surface of the sealing tub 12. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

In the waterproof pan and drainage trap for the washing machine of the first embodiment configured as described above, due to long-term use, dirt adheres to the inside of the drainage trap T, and a strange odor is produced, such as accumulated hair and lint. When pipe clogging occurs due to dust, dirt components, etc., and it becomes necessary to clean the inside of the drain trap T, the member of the drain trap T can be taken out and cleaned by the following method.
First, the wall member 8 is removed from the recess 5 to secure a clearance space in which the operator's hand can be inserted into the peripheral wall 3.
Next, the diameter of the notch is expanded, the eye plate member 11 is removed from the washing machine connecting pipe 16 or the washing machine drain hose, and taken out to the outside of the peripheral wall 3 through the step 6 and the recess 5.
Next, the connection between the washing machine connection pipe 16 and the washing machine drain hose is released, and then the connection between the deodorizing cylinder 13 and the flange member 10 is released.
Thereafter, the deodorizing cylinder 13, the washing machine connection pipe 16, and the water seal 12 are taken out of the peripheral wall 3.
When the member of the drain trap T is taken out, the cleaning operator takes the following reasons when taking out the members such as the deodorizing cylinder 13 and the water seal 12. To reason 3 For this reason, the deodorizing cylinder 13 and the water seal 12 are taken out from the opening 2a at the bottom (in the case of this embodiment, the drain port 10b inside the flange member 10) and moved horizontally without being inclined. Thus, as shown in FIG. Therefore, it is almost certainly eliminated that the sealed water (drainage) in the sealed water bottle 12 is spilled on the bottom surface 2 other than the step portion 6.
Reason 1. In this embodiment, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, and the vertical width of the deodorizing cylinder 13 is configured to be shorter than the horizontal width of the sealed water jar 12, As in the conventional example, there is no merit in inclining the sealed water bottle 12 or the deodorizing cylinder 13 (especially the sealed water bottle 12), and it is preferable to move it horizontally without being inclined and take it out from the peripheral wall 3. Consists of.
Reason 2 In the cleaning operation, the step portion 6 functions as a guide, and has an effect of preventing members such as the deodorizing cylinder 13 and the water seal 12 from being inclined in the lateral direction.
Reason 3. The bottom ends of the water seal 12, the deodorizing cylinder 13, and the recess 5 are configured to be substantially horizontal when viewed from the side. Thereby, when taking out the sealing water bottle 12 and the deodorizing cylinder 13 from the recessed part 5, it functions as a guide which takes out the sealing water bottle 12 and the deodorizing cylinder 13 without inclining, and members, such as the deodorizing cylinder 13 and the sealing water bottle 12, are sideways. There is an effect of preventing tilting in the direction.

Furthermore, in this embodiment, the height width H2 from the bottom surface 2 other than the step portion 6 to the upper end of the footrest 4 is made narrower than the height width of the sealing jar 12 and the deodorizing cylinder 13, so It is impossible to move the water seal 12 and the deodorizing cylinder 13 on the bottom surface 2. Thereby, it is surely prevented that the sealed water (drainage) in the sealed water bottle 12 is spilled on the bottom surface 2 other than the step portion 6. Even if the spilled water is spilled, the sealed water is spilled only on the stepped portion 6 communicating with the recessed portion 5, so that the portion that needs to be cleaned is easily visible and the operator can easily insert the hand into the recessed portion 5. And it is limited only to the step part 6, and cleaning is very easy.

After removing the member from the drain trap T and cleaning it in this way, in some cases, cleaning the inside of the trap body 9 or cleaning the pipe downstream from the discharge port 9a / resolving clogging of the equipment, etc. After carrying out the work through the recess 5 and the drain port 10b to perform the cleaning work / clogging of the tube, the work other than placing the washing machine L on the waterproof pan 1 for the washing machine described in paragraph 0021 is performed. By repeating, the attachment operation | work of the member of the drain trap T is completed, and the cleaning operation | work of the drain trap T is completed.

The eye plate member 11 can be taken out without releasing the connection with the water drain hose.
Of the above members, the lower end portions of the water seal 12, the deodorizing cylinder 13, and the connecting pipe 16 for the washing machine are configured to be substantially horizontal when viewed from the side. As described above, the term “horizontal” as used herein is an expression indicating that it is formed in a shape that is parallel to the side view horizontal plane in a state where construction and attachment of each member are completed. It does not indicate a “flat surface”. Strictly speaking, the lower end portion of the deodorizing cylinder 13 has a cylindrical shape and is not a “surface”, but this is a virtual flat surface formed by continuing the cylindrical lower end portion. This indicates that the surface is parallel to the side view horizontal plane in the state where the attachment of the member is completed.
Further, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, and the vertical width of the deodorizing cylinder 13 is configured to be shorter than the horizontal width of the sealed water jar 12.
Further, in this embodiment, the deodorizing cylinder 13 and the sealing water bottle 12 are engaged with each other at the claw portion 13b as described above, so that the water is sealed between the deodorizing cylinder 13 and the sealing water bottle 12 as shown in FIG. The unit 14 is configured. In the state of the sealing water unit 14, the deodorizing cylinder 13 is arranged at a position that covers the sealing water bottle 12, so that the sealing water (drainage) inside the sealing water bottle 12 is more reliably prevented from spilling out. can do.
Even in the state of the sealed water unit 14, the vertical width of the sealed water unit 14 is configured to be shorter than the horizontal width of the sealed water unit 14.
Furthermore, in the state of the sealing unit 15 with the connecting pipe, the drain connecting pipe for the washing machine is configured to protrude slightly above the deodorizing cylinder 13. The vertical width from the upper end of the drainage connection pipe for washing machine to the lower end of the sealing tub 12 in the state where the drainage connection pipe for washing machine is combined with the sealing water unit 14 is from the lower end of the recess 5 to the upper end of the footrest 4. The height is configured to be narrower than the width H1 .
Further, as described above, the washing machine connecting pipe 16 is housed inside the deodorizing cylinder 13 and the water seal 12, and the end of the horizontal tube portion of the washing machine connecting pipe 16 is deodorized at both ends. The cylinder 13 is configured to protrude slightly outward from the outer surface of the cylindrical portion 13a. Therefore, when the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked up and pulled up as it is, the deodorizing cylinder 13 is mounted on both ends of the horizontal pipe portion of the connecting pipe 16 for the washing machine. (Since the horizontal tube portion is flattened, the top surface is flat, and the deodorizing cylinder 13 is stable at both ends of the horizontal tube portion of the connecting pipe 16 for the washing machine. In addition, since the deodorizing cylinder 13 and the sealing water bottle 12 are engaged by the claw portion 13b, the sealing unit with a connecting pipe 15 is maintained in a horizontal state. It can be easily pulled up.
The washing machine L disposed on the waterproof pan 1 for a washing machine is a drainage device (a device that generates drainage by use) that has a substantially box shape, and has a loading port for laundry on the side surface, With four legs and a washing machine drain hose (only the elbow pipe E is shown) for discharging waste water containing detergent and dirt components generated by using the washing machine L It becomes.

The washing machine waterproof pan and the drain trap configured as described above are constructed as follows. Although not particularly described, in the following construction, a portion requiring watertight connection is watertightly connected by screw connection using adhesion or packing as necessary.
First, an opening for arranging the trap body 9 is provided on the floor surface F. Next, the discharge port 9a of the trap body 9 is connected to the sewage side pipe through this opening. Further, the tubular portion 13a of the flange member 10 is inserted into the opening 2a, and the flange portion 10a of the flange member 10 is accommodated on the upper surface of the stepped portion 2b. Screw onto the female screw. Accordingly, the lower surface of the opening 2a of the waterproof pan 1 for a washing machine, that is, the bottom surface 2 of the stepped portion 2b is sandwiched between the lower surface of the flange portion 10a of the flange member 10 and the upper surface of the convex portion 9b of the trap body 9. Thus, the trap body 9 and the flange member 10 are fixed to the waterproof pan 1 for a washing machine.
Further, the waterproof pan 1 for a washing machine is fixed on the floor surface F using screws or the like.
At this time, in this embodiment, as described above, regarding the vertical positional relationship between the lower end of the back surface of the step pressing portion 2b and the lower end of the outer peripheral wall 3, the lower end of the back surface of the step pressing portion 2b is The opening provided for disposing the drainage trap T on the floor F has a width equal to or greater than the thickness of the convex portion 9b of the trap body 9 in the vertical direction. It is sufficient to open only in accordance with the side shape of the main body 9.
Briefly, if there is a wide gap between the opening of the floor surface F and the peripheral edge of the convex portion 9b, or if the floor surface F does not exist below the convex portion 9b, ventilation in the underfloor space, etc. Leaks from the gap between the convex portions 9b, causing unnecessary ventilation on the indoor side and causing the occupant to feel uncomfortable. In order to prevent this, in the case of the conventional example, the opening of the floor surface F has to be formed in a two-stage shape in which a step is provided on the side surface of the trap body 9 in accordance with the opening on the periphery of the convex portion 9b. However, in the second embodiment, since the convex portion 9b does not bite into the floor surface F, it is only necessary to open the floor surface F according to only the side surface shape excluding the convex portion 9b of the trap body 9, Since the work is simplified, workability can be improved (to accommodate the discharge port provided on the side surface, it is partially enlarged, and after installing the trap body, an extra opening is made with a plate. (It is not shown in FIG.

Next, the connection configured by engaging the deodorizing cylinder 13 and the sealing water bottle 12 with the claw portion 13b in a state where the washing machine connection pipe 16 is housed inside the deodorizing cylinder 13 and the sealing water bottle 12. The sealed water unit 15 with a pipe is inserted through the opening 2 a of the flange member 10. Thereafter, the sealing tub 12 is suspended inside the flange member 10 so as to be disposed inside the trap body 9 and the mortar-shaped portion at the upper end of the deodorizing cylinder 13 housing the connecting pipe 16 for the washing machine inside. The outer peripheral portion is watertightly connected to the inner surface of the flange member 10.
As a result, the connecting pipe 16 for the washing machine is in a state in which the T-shape is turned upside down, and the ends of the horizontal tube part are slightly outside the outer surface of the cylinder part 13a of the deodorizing cylinder 13 at both ends. Can be attached to the inside of the drain trap T.
In this state, the opening inside the flange member 10 functions as the drain port 10b. Further, the eye plate member 11 is set in the drain port 10b, and the washing machine drain hose is connected to the washing machine connection pipe 16 using the elbow pipe E or the like, and the leg of the washing machine L is placed on the footrest 4. Is placed. Finally, the wall member 8 is watertightly attached to the recess 5 to complete the construction of the waterproof pan for the washing machine, the drain trap, and the washing machine.

The washing machine waterproof pan and drain trap configured as described above are used as follows.
When the washing machine L is used and drainage is generated from the washing machine L, the drainage from the washing machine L flows from the washing machine drain hose through the washing machine connection pipe 16 into the sealed water bottle 12 and accumulates. When it is sufficiently collected, it overflows from the opening provided on the side surface of the sealing tub 12. The waste water that has flowed out of the sealing tub 12 is discharged from the inside of the trap body 9 to the sewage side through the discharge port 9a. At this time, since the ends of the horizontal tube portion of the connecting pipe 16 for the washing machine are configured so that both ends protrude slightly outward from the outer surface of the tube portion 13a of the deodorizing tube 13, the washing machine The bubble-mixed waste water from L is first discharged only to the outside of the cylindrical portion 13 a of the deodorizing cylinder 13 and is not discharged to the inside of the deodorizing cylinder 13. Since the bubbles in the drainage are lifted with respect to the drainage by the buoyancy, the bubbles in the drainage discharged to the outside of the cylindrical portion 13a of the deodorizing cylinder 13 are directly between the outer surface of the deodorizing cylinder 13 and the inner surface of the sealing tub 12. And is discharged downstream from the opening on the side surface of the sealing tub 12 and does not flow backward from the inner surface of the deodorizing cylinder 13 to the drain port 10b.
Further, when drainage occurs on the bottom surface 2 of the washing machine waterproof pan 1 due to damage to the washing machine L itself or the washing machine drain hose, the drainage passes over the bottom surface 2 of the washing machine waterproof pan 1. Then, it passes through the eye plate member 11 of the drain port 10b, passes in the order of the inside of the deodorizing cylinder 13, the inside of the sealed water bottle 12, the opening above the sealed water bottle 12, the inside of the trap body 9 and the discharge port 9a. Discharged to the sewage side.
In addition, since the wall member 8 is watertightly attached to the recess 5 of the peripheral wall 3, even if drainage occurs inside the waterproof pan 1 for a washing machine, as long as the drainage does not accumulate at the upper end of the peripheral wall 3, Does not overflow from the inside of the waterproof pan 1 for a washing machine.
Further, in the drain trap T configured as described above, when drainage is performed in the drain trap T via the washing machine connection pipe 16 or the drain port 10b, the bottom end of the side opening is placed inside the sealing tub 12. Drainage collects up to the height. Thus, a portion filled with drainage is formed in the flow path from the drain outlet 10b or the connecting pipe 16 for the washing machine to the lower end of the opening 2a on the side surface of the sealing tub 12. This accumulated drainage is called sealed water, and even if odors and pests try to enter the indoor side from the sewage side, the sealed water can prevent further intrusion into the indoor side. Thus, the function of preventing odors and pests from entering the indoor side from the sewage side is called a trap function.

In the waterproof pan and drainage trap for the washing machine of the second embodiment configured as described above, due to long-term use, dirt adheres to the inside of the drainage trap T, and a strange odor is produced, such as accumulated hair and lint. When pipe clogging occurs due to dust, dirt components, etc., and it becomes necessary to clean the inside of the drain trap T, the member of the drain trap T can be taken out and cleaned by the following method.
First, the wall member 8 is removed from the recess 5 to secure a clearance space in which the operator's hand can be inserted into the peripheral wall 3.
Next, the diameter of the notch is expanded, the eye plate member 11 is removed from the washing machine connecting pipe 16 or the washing machine drain hose, and taken out to the outside of the peripheral wall 3 through the step 6 and the recess 5.
Next, the connection between the washing machine connection pipe 16 and the washing machine drain hose is released, and then the connection between the deodorizing cylinder 13 and the flange member 10 is released.
Thereafter, the sealing unit with connection pipe 15 is taken out of the peripheral wall 3.
When the member of the drain trap T is taken out, the cleaning operator takes the reason described below when taking out the sealing unit 15 with a connecting pipe. To reason 6 For this reason, the sealing unit with connection pipe 15 is taken out from the opening 2a at the bottom (in the case of the present embodiment, the drain port 10b inside the flange member 10), and is tilted as it is as shown in FIG. It is moved horizontally without taking out from the recess 5. Therefore, the sealed water (drainage) in the sealed water tub 12 is almost certainly not spilled on the bottom surface 2.
Reason 4 In the present embodiment, the vertical width of the sealed water jar 12 is shorter than the horizontal width of the sealed water jar 12, the vertical width of the deodorizing cylinder 13 is shorter than the horizontal width of the sealed water jar 12, and the sealed water unit 14 is also drained. The vertical width of the unit is configured to be shorter than the horizontal width of the drainage unit (in the state of the sealing unit 15 with connecting pipe, the vertical width and the horizontal width are substantially the same, and the vertical width is slightly shorter).
For this reason, there is no merit in inclining the sealed water bottle 12 or the deodorizing cylinder 13 (especially the sealed water bottle 12) as in the conventional example, and it is preferable to move it horizontally without taking it out and to take it out from the peripheral wall 3. It is comprised so that.
Reason 5. The bottom end of each of the water seal 12, the deodorizing cylinder 13, and the recess 5, particularly the bottom end of the water seal 12 that is the lower end of the water seal unit 15 with a connecting pipe is configured to be substantially horizontal when viewed from the side. Become. Thus, when the sealing unit with connection pipe 15 is taken out from the recess 5, it functions as a guide for taking out the sealing unit with connection pipe 15 without tilting, and the deodorizing cylinder 13 constituting the sealing unit with connection pipe 15, sealing There exists an effect which prevents that members, such as the water tank 12, incline to a horizontal direction.
Reason 6 In the sealing unit 15 with connecting pipe, when the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and pulled up as it is, the deodorizing cylinders are attached to both ends of the horizontal pipe portion of the connecting pipe 16 for the washing machine. Since the deodorizing cylinder 13 and the sealing tub 12 are engaged by the claw portion 13b, the members of the sealing unit with a connecting pipe 15 are maintained in a horizontal state. Can be pulled up easily. At this time, the connection of the deodorizing cylinder 13, the water seal 12 and the connecting pipe 16 for the washing machine is not fixed and is merely an engagement degree with mounting and play. Even if the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and tilted, the sealing water of the sealing tub 12 acts like a weight and cannot be tilted as desired by the operator.
As a result, when the cleaning operator moves the sealing unit 14, the vertical pipe body at the center of the connecting pipe 16 for the washing machine is picked and maintained in a horizontal state without tilting the sealing unit 14. Will be moved.

After removing the member from the drain trap T and cleaning it in this way, in some cases, cleaning the inside of the trap body 9 or cleaning the pipe downstream from the discharge port 9a / resolving clogging of the equipment, etc. After performing the work through the recess 5 and the drain port 10b to perform cleaning work / clogging of the pipe, work other than placing the washing machine L on the waterproof pan 1 for the washing machine described in paragraph 0028 is performed. By repeating, the attachment operation | work of the member of the drain trap T is completed, and the cleaning operation | work of the drain trap T is completed.

The embodiments of the present invention are as described above. However, the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention.
For example, in the second embodiment, the drainage trap T that becomes the sealing unit 14 by engaging the sealing jar 12 and the deodorizing cylinder 13 with the waterproof pan 1 for a washing machine that does not have the stepped portion 6 is adopted. However, the present invention is not limited to the above embodiment, and the drain trap T in which the sealing tub 12 and the deodorizing cylinder 13 are not engaged with the waterproof pan 1 for a washing machine not having the stepped portion 6. May be adopted. Even in this case, Reason 1. Reason 2 (Or Reason 4. and Reason 5.), when the member of the drain trap T is taken out, the worker of the cleaning work takes out the deodorizing cylinder 13 from the opening 2a at the bottom when taking out the sealing unit 15 with the connecting pipe. Then, the member of the drain trap T such as the sealing tub 12 is taken out upward, moved as it is without being inclined, and taken out from the recess 5. Therefore, the sealed water (drainage) in the sealed water tub 12 is almost certainly not spilled on the bottom surface 2.
