Description

  The present invention relates to an assembly of a waterproof pan and a drain trap on which a washing machine is placed.

  2. Description of the Related Art Conventionally, there is a waterproof pan provided with a mount on which legs of a washing machine are placed and a mounting hole to which a drain trap is attached (see Patent Document 1).

  In the waterproof pan, the attachment hole is located below the washing machine in a state where the washing machine is installed in the waterproof pan. The height of the gantry is set higher than the height of the drain trap so that the drain trap can be taken out without inclining the deodorizing cylinder and the sealing tank for the purpose of improving the maintainability of the drain trap. .

Japanese Patent No. 5130447

  In a washing machine, the height of the laundry inlet varies depending on the type of washing machine. For example, a washing machine (hereinafter referred to as a vertical washing machine) in which the laundry inlet is directed in the vertical direction rather than a washing machine (hereinafter referred to as a horizontal washing machine) in which the laundry inlet is oriented in the horizontal direction. However, the height of the inlet tends to be higher.

  When a horizontal washing machine is placed on the above-described waterproof pan, workability in taking out the laundry is not significantly reduced even if the height of the insertion opening is increased by the height of the gantry. On the other hand, when the vertical washing machine is placed, the workability in taking out the laundry is lowered by increasing the height of the laundry input by the height of the gantry. In particular, the laundry at the bottom of the laundry tub is very difficult to take out. Therefore, when a short person works, it may be necessary to take out the laundry on a step board. Therefore, depending on the type of washing machine, it is better to place the washing machine directly on the waterproof pan without installing the stand on the waterproof pan. It may be preferable to increase the height.

  However, in the case of the waterproof pan described above, the mounting hole is located below the installed washing machine. Therefore, when the washing machine is placed directly on the waterproof pan, the washing machine installed on the waterproof pan must be moved to remove the drain trap attached to the mounting hole. That is, there is a problem that the maintainability of the drain trap is lowered.

  In order to avoid the problem, it is conceivable to increase the length of the waterproof pan in the width direction and arrange the attachment hole at a position different from the area where the washing machine is installed. In this case, the diameter and arrangement position of the mounting hole in the waterproof pan for a washing machine are set based on the excellent housing part certification standard established by Better Living. Specifically, the mounting hole diameter is set to 119 mm (within ± 1.0 mm), and the center of the mounting hole is set to 123 mm (within ± 2.5 mm) from the short side edge or long side edge of the waterproof pan. Has been. Furthermore, when the washing machine is placed directly on the waterproof pan, there is not enough space between the installed washing machine and the mounting hole. Cannot be placed close to the area. Therefore, in order to arrange the attachment hole at a position different from the area where the washing machine is installed, it is necessary to significantly increase the length of the waterproof pan in the width direction. As a result, there is a problem that the place where the waterproof pan can be installed is limited due to an increase in the installation width of the waterproof pan.

  Therefore, the present invention has been made to solve the above problems, and is installed by attaching a small trap capable of maintaining the maintainability of the drainage trap even when the washing machine is directly placed. An object is to provide a waterproof pan that does not require an increase in width.

  The waterproof pan according to the present invention that achieves the above object is a bottom surface portion formed in a rectangular plate shape on which a washing machine is placed and a vertical wall portion provided on the outer periphery of the bottom surface portion, The bottom surface portion includes an attachment hole for attaching a drain trap, and the center of the attachment hole is located in a range of 50 mm or more and less than 123 mm from the vertical wall portion provided on the short side of the bottom surface portion.

  According to the waterproof pan of the present invention, even if the mounting hole is arranged close to the installation area of the washing machine, the drainage trap can be easily made without increasing the width of the waterproof pan as compared with the conventional waterproof pan. Can be taken out. Therefore, it is possible to provide a waterproof pan that does not need to increase the installation width that can maintain the maintainability of the drain trap even when the washing machine is directly placed.

More specifically, it is provided close to the installation area S where the washing machine is installed. More specifically, the mounting hole 30 partially overlaps the installation area S. The gantry 40 is formed in an installation area S where the washing machine is installed.

<Drain trap>
Next, the configuration of the drain trap 200 according to the present embodiment will be described with reference to FIGS.

  FIG. 7 is an exploded perspective view showing the drain trap 200 disassembled for each component. FIG. 8 is an enlarged view corresponding to a portion surrounded by a broken line portion M2 in FIG. 5A in a state where the drain trap 200 is attached to the waterproof pan 100. FIG. FIG. 9 is a cross-sectional view showing a drain trap 400 of a comparative example.

  Referring to FIG. 8, the drain trap 200 guides the second flow path L2 into which the water F2 in the bottom surface portion 10 of the waterproof pan 100 flows into the first flow path L1 into which the drainage F1 from the washing machine flows. Compared to the case where the first flow path L1 and the second flow path L2 are provided separately (see the comparative example in FIG. 9), the diameter Da of the tub 203 for storing the sealed water is made smaller. Sealed water is drainage stored in a drain trap, and has a role of preventing odors and the like from the drain pipe from entering the indoor side.

  Specifically, the drain trap 200 stores the drainage and overflows the drainage into the drainpipe while overflowing the drainage. The drain trap 200 is immersed in a part of the drainage in the trough 203 to connect the drainage pipe side and the indoor side. It has a sealing tube 204 that partitions, and a casing 201 that supports the flange 203 and the sealing tube 204 in a state in which the sealing tube 204 is housed inside. Further, the drain trap 200 has a pan support 208 that attaches the casing 201 to the mounting hole 30 of the waterproof pan 100 and holds the pan 209, and a drain joint 210 that guides drainage to the sealing tube 204. Hereinafter, each component will be described in detail.

  The casing 201 includes a discharge unit 201a that distributes the drainage discharged from the basket 203 to a drain pipe (sewage pipe).

  The flange 203 includes a plurality of openings 203c at the upper part of the side surface 203b, and an outer edge 203d at the lower end of the opening 203c. The flange 203 is formed by vertically forming the lower portion and the upper portion of the side surface 203b and inclining the central portion of the side surface 203b. The lower part of the side surface 203b has a smaller diameter than the upper part of the side surface 203b.

  The sealing tube 204 is accommodated in the flange 203 with the lower portion 204 a being separated from the bottom surface 203 a of the flange 203. The sealing tube 204 includes a first inclined portion 204c formed on the upper side, a flat portion 204d formed on the lower side, and a second inclined portion 204e that connects the first inclined portion 204c and the flat portion 204d. Including. Further, the water seal tube 204 includes a joint receiving portion 205 connected to the upper portion 204b of the water seal tube 204 through the bridging portion 205b (see FIG. 7). The joint receiving portion 205 is held in a state where the drain joint 210 is accommodated.

  An upper portion 208 a of the eye plate receiver 208 is in contact with the inner peripheral surface 31 and the first step portion 32 of the mounting hole 30 of the waterproof pan 100. The eye plate 209 discharges the drainage or the like accumulated on the bottom surface portion 10 of the waterproof pan 100 to the sealing tube 204. The drainage joint 210 connects a drainage hose of a washing machine, for example, and guides drainage discharged from the drainage hose to the sealing tube 204.

  A space between the housing 201 and the eye plate receiver 208 is sealed with a U-shaped packing 207. The U-shaped packing 207 is attached to the second step portion 33 of the attachment hole 30 of the waterproof pan 100. Further, a space between the sealing tube 204 and the eye plate receptacle 208 is sealed with a flat packing 206. A space between the U-shaped packing 207 and the countersunk tray 208 is sealed with a slip packing 202 (see FIG. 7).

  As shown in FIG. 8, in the drain trap 200, a first flow path L1 into which drainage F1 from the washing machine flows is formed inside the drainage joint 210. In addition, a second flow path L <b> 2 through which water F <b> 2 from the bottom surface portion 10 of the waterproof pan 100 flows is formed between the joint receiving portion 205 and the first inclined portion 204 c of the sealing tube 204. And the 2nd flow path L2 merges with the 1st flow path L1 by the 2nd inclination part 204e of the sealing cylinder 204. FIG. Thereby, compared with the case where the 1st flow path L1 and the 2nd flow path L2 are provided separately, the diameter Da of the collar 203 is made small. The “diameter of the heel” refers to the diameter of the outermost contour when the portion between the bottom surface 203a and the opening 203c in the heel 203 is viewed in plan.

  Referring to FIG. 9, the diameter Da of the rod 203 is smaller than that in the case where the first flow path L1 and the second flow path L2 are provided separately, compared with the configuration of the drain trap 400 of the comparative example. Will be described in detail.

  The drain trap 400 of the comparative example includes a housing 401, a slip packing 402 (not shown), a gutter 403, a sealing tube 404, a defoaming tube 405, a flat packing 406 (not shown), and a U-shape. A packing 407, an eye plate receiver 408, an eye plate 409, and a drainage joint 410 are included. Since the configurations of the casing 401 to the trough 403 are substantially the same as the configurations of the casing 201 to the trough 203 of the drain trap 200, description thereof will be omitted. Further, since the configuration of the flat packing 406 to the drainage joint 410 is substantially the same as the configuration of the flat packing 206 to the drainage joint 210 of the drain trap 200, description thereof will be omitted.

  The sealing cylinder 404 is accommodated in the tub 403 in a state where the lower part 404 a is separated from the lower part 405 a of the defoaming cylinder 405. The defoaming cylinder 405 is accommodated in the ridge 403 in a state where the lower portion 405a is separated from the bottom surface 403a of the ridge 403.

  In the drain trap 400, the first flow path L1 into which the waste water F1 from the washing machine flows is formed inside the drain joint 410. And the 2nd flow path L2 into which the water F2 from the bottom face part of a waterproofing pan flows is formed between the water-sealing cylinder 404 and the defoaming cylinder 405. That is, in the drain trap 400 of the comparative example, the first flow path L1 and the second flow path L2 are provided separately.

  On the other hand, in the drain trap 200, the 2nd flow path L2 is guide | induced to the 1st flow path L1 (refer FIG. 8). Thereby, the space between the sealing cylinder 404 and the defoaming cylinder 405 formed in the drain trap 400 of the comparative example can be omitted. Therefore, in the drainage trap 200, the diameter Da of the rod 203 can be reduced as compared with the drainage trap 400 of the comparative example without impairing the drainage capacity.

  In the present embodiment, the inner diameter Db of the drainage joint 210 is set to be larger than 30 mm and not more than 40 mm. Further, the diameter Da of the flange 203 is set within a range of 60 to 70 mm. Since the outer diameter of the drainage hose attached to (connected to) a general washing machine is 30 mm, the inner diameter Db of the drainage joint 210 is larger than 30 mm and within the range of 40 mm or less. The drainage joint 210 can be connected to a drainage hose of a typical washing machine. Further, when the inner diameter Db of the drainage joint 210 is larger than 30 mm and within the range of 40 mm or less, the drainage from the washing machine can flow into the drainage trap 200 without stagnation in the drainage hose. Further, when the diameter Da of the rod 203 is less than 60 mm, the drainage flow rate per hour of the drainage trap 200 decreases as compared with the comparative example, and even when it exceeds 70 mm, the drainage flow rate per hour particularly increases. No.

  Next, with reference to FIG. 10, an operation when the tub 203 and the sealing tube 204 in the drain trap 200 are taken out from the mounting hole 30 of the waterproof pan 100 will be described.

  FIG. 10 (A) is a schematic view showing a state in which the basket 203 and the sealing tube 204 in the drain trap 200 are taken out from the mounting hole 30 of the waterproof pan 100, and FIG. 10 (B) shows a waterproof pan 600 of a comparative example. It is the schematic which shows a mode that the trough 403, the sealing cylinder 404, and the defoaming cylinder 405 in the drain trap 400 are taken out from the attachment hole 630. FIG. FIGS. 10A and 10B and FIGS. 13A and 13B illustrate an example in which the washing machine 500 is directly placed on the waterproof pan without providing the gantry 40. Even when 40 is provided, there is no substantial difference in the content of the description.

  10A and 10B, the width W0 of the waterproof pan 100 and the width of the waterproof pan 600 are the same. And the center Cp of the attachment hole 30 in the waterproof pan 100 exists in the range whose distance L from the vertical wall part 21 is less than 123 mm. On the other hand, the distance Cc from the vertical wall portion 621 is set to 123 mm at the center Cpc of the mounting hole 630 of the waterproof pan 600. Moreover, the size of the washing machine 500 mounted on the waterproof pan 100 and the waterproof pan 600 is the same.

  As shown in FIG. 10B, when the washing machine 500 is placed on the waterproof pan 600 of the comparative example, when the basket 403, the sealing tube 404, and the defoaming tube 405 in the drain trap 400 are taken out from the mounting hole 630. In addition, the lower part of the washing machine 500 and the sealed water bottle 404 come into contact with each other. The drain trap 400 has a structure in which the bottle 403 and the defoaming cylinder 405 cannot be taken out unless the sealed water pipe 404 is taken out. Therefore, in the state where the washing machine 500 is placed, the bag 403, the water seal tube 404, and the defoaming tube 405 cannot be taken out.

  On the other hand, as shown in FIG. 10A, in the case of the waterproof pan 100 according to the present embodiment, the center Cp of the mounting hole 30 is arranged in a range where the distance L from the vertical wall portion 21 is less than 123 mm. It becomes possible. In other words, even if the attachment hole 30 is arranged close to the installation area S of the washing machine, the bag 203 and the seal in the drain trap 200 are not increased without increasing the width W0 of the waterproof pan 100 compared to the waterproof pan 600. The water bottle 204 can be easily taken out. Specifically, when the basket 203 and the sealing cylinder 204 in the drain trap 200 are taken out from the mounting hole 30, it is possible to prevent the bottom of the washing machine 500 from contacting the casing 203 and the sealing cylinder 204. Therefore, even when the washing machine 500 is directly placed, the basket 203 and the sealed water tube 204 can be easily taken out. As described above, since the width W0 of the waterproof pan 100 and the width of the waterproof pan 600 are the same, the maintainability of the drain trap can be improved without increasing the installation width.

  In the present embodiment, [10 mm (lower limit of thickness U of vertical wall portion 21)] + [80 mm (lower limit of diameter d0 of mounting hole 30) / 2] = 50 mm is set on the short side SS side of bottom surface portion 10. The lower limit of the distance L from the provided vertical wall portion 21 to the center Cp of the mounting hole 30 is set. However, as long as the effect of improving the maintainability of the drain trap without increasing the installation width, it is not particularly necessary to provide a lower limit for the distance L to the center Cp of the mounting hole 30. In addition, when the drainage trap 200 that can be attached to the waterproof pan 100 having a distance L from the vertical wall portion 21 to the center Cp of the attachment hole 30 of 50 mm or more and less than 123 mm is confirmed and confirmed to be attached / detached, there is no problem. It was confirmed.

  Next, the operation of the drain trap 200 according to the present embodiment will be described with reference to FIG. In the following, the operation of the drain trap 200 will be described by taking as an example the case where the drainage F1 from the washing machine and the water F2 from the bottom surface portion 10 of the waterproof pan 100 flow into the drain trap 200 at the same time. However, even when any one of the waste water F1 from the washing machine and the water F2 from the bottom surface portion 10 of the waterproof pan 100 flows into the drain trap 200, there is no substantial difference in the operation of the drain trap 200.

  FIG. 11A is a cross-sectional view showing the operation of the drain trap 200, and FIG. 11B is a cross-sectional view showing the operation of the drain trap 400 of the comparative example. In FIG. 11A and FIG. 11B, a part of the waterproof pan 100 and the drainage joint 210 (410) is omitted.

  First, the operation of the drain trap 400 of the comparative example will be described with reference to FIG.
