Description

  The present invention relates to a drain trap provided at a drain outlet of a bathroom or the like.

  In order to prevent odors (sewage gas) and small insects from the sewage pipes from entering the room, a water-sealed drain trap is installed at the drainage outlet of the bathroom washroom or the bathroom. Usually it is provided. Many of these water-sealed traps are broadly divided into tube traps and traps with caps (caps) with movable parts. Under the entrance), there is a sealed water part where the drained water always passes and a part of it is collected. It is structured to block sewage gas.

  Of these, trapezoidal traps (hereinafter also simply referred to as traps) usually have a bottomed cylindrical (container-shaped) trap body with an open top, usually a cylindrical drainage tube in the center of the bottom, and its drainage. In addition to accumulating water around the cylinder, the drain cylinder is covered with a cap-shaped cap (cap) so that water can pass through it (water passage), and the water and the dredged water cover the indoor space and drain pipe. It is set as the structure which interrupts | blocks the downstream side space. In such a drain trap, if the state where water does not flow is continued for a long time, the water stored as sealed water evaporates and decreases, eventually depleting, and the trap function is lost. is there. On the other hand, a float having a size capable of closing the upper end opening is placed on the upper end opening of the drain tube, and when the drainage is not being performed, the upper end opening is opened by the weight of the float. There is a float-type drainage trap that is closed and drained by buoyancy caused by the drainage to open the top opening and allow drainage.

As an example, a guide rod is vertically supported at the center of a drain tube (outflow tube) provided at the bottom of the trap body (hereinafter also simply referred to as a main body). There is one in which a float having a large diameter and an annular body having a required height connected to the lower surface of the outer peripheral portion is attached so as to be movable up and down (Patent Document 1). The purpose of this is to raise the float along the guide rod in response to the water level rising in the main body during drainage, thereby simplifying the flow path when drainage flows and smoothing the drainage. In addition to this, even if the water in the trap is depleted, the lower surface of the float is in close contact with the upper end of the drainage cylinder due to its own weight. Intrusion is prevented. For this reason, when the drainage is not performed, the upper end opening of the drain tube is closed by the weight of the float, and when the drainage is performed, the upper end opening is opened by the buoyancy caused by the drainage to drain the water. It can also be used as a float drain trap.

  However, in the structure described in Patent Document 1, due to its structure, separately from the float, a guide rod for moving the float up and down (moving up and down) and another member (part) for supporting (fixing) the guide rod. Or a special structure is required. For this reason, the number of parts constituting the trap increases, and the structure becomes complicated. Therefore, there is a problem that malfunction tends to occur and stable drainage cannot be performed.

  In addition, in the conventional trap-shaped drainage trap, the trap is damaged or lost after the removal, and the trap function is unknown by the user. It is often used for. For example, in the case of a detached house, an appropriately-sized cocoon suitable for a trap that has been provided since the new construction is often not distributed to general stores and is difficult to obtain. This is especially true for detached houses that are old. Also, in a detached house, the bathroom washroom is tiled, and the drainage trap provided at the drainage outlet of such a floor part can not be easily replaced because it requires tile work, etc. In many cases, it is used without being covered with cocoons.

  The present invention has been made in view of these points, and provides a float-type drainage trap having a simple structure, and in a bowl-shaped drainage trap provided in, for example, a bathroom washing place of an existing detached house. It is an object of the present invention to provide a float for a drain trap that can be easily realized as a float drain trap by being attached as an alternative to the kite.

In the first aspect of the present invention, a float having a size capable of closing the upper end opening is disposed in a mounting manner with respect to the upper end opening of the drainage pipe standing upright at the bottom of the trap body having an upper opening. When the drainage is not performed, the upper end opening is closed by the weight of the float, and when the drainage is performed, the upper end opening is moved up by the buoyancy caused by the drainage so that the drainage is performed. In the structure drain trap,
The float is formed so that its outer peripheral surface moves up and down while being guided by the inner peripheral surface of the trap body, and the float is located above the float in a portion located outside the upper end opening in plan view. A water passage is formed in which the space and the space outside the drain tube are connected.

  According to a second aspect of the present invention, in the first aspect of the invention, instead of forming the float so that the outer peripheral surface thereof is guided by the inner peripheral surface of the trap body and moves up and down, the float includes the float. The drainage trap is formed so that the outer circumferential surface is guided by the inner circumferential surface of a connecting tube provided concentrically at the upper part in the trap body so as to move up and down.

According to the third aspect of the present invention, a float having a size capable of closing the upper end opening is arranged in a mounting manner with respect to the upper end opening of the drainage pipe standing upright at the bottom of the trap body whose upper part is opened. When the drainage is not performed, the upper end opening is closed by the weight of the float, and when the drainage is performed, the upper end opening is moved up by the buoyancy caused by the drainage so that the drainage is performed. In the structure drain trap,
The float is characterized in that a guide portion that is inserted into the drainage cylinder and serves as a guide when the float moves up and down is integrally formed at a lower portion of the float.

In the lower part of the float itself, a guide portion that is inserted into the drain tube and serves as a guide when the float moves up and down is integrally formed.

  The drain trap according to the present invention is of a float type, but since a separate member (part) is not required as a guide for moving the float up and down, the number of parts constituting the trap may also increase. There is no complication. For this reason, since there is little danger that the malfunction will generate | occur | produce in the operation | movement, there exists an effect that the stable drainage can be performed.

  The drain trap float according to the present invention is very convenient because it can be easily used in place of a damaged soot in an existing drain trap. That is, the drain trap float according to the present invention does not require a separate part for the guide, because it can be mounted just by placing it on the drain tube of the existing trap body, In the case where it is used without any wrinkles, a float drain trap can be easily obtained.

  An embodiment of the drain trap according to claim 1 of the present invention will be described with reference to FIGS. In FIG. 1, F is a floor of a bathroom washroom where a drain trap (floor drain trap) 1 of this example is constructed. The drain trap 1 of the present embodiment has a main body 1a having a bottomed cylindrical container shape that opens upward, and a cylindrical drain tube 4 is concentrically provided at the center of the bottom portion 3 so as to stand upright. ing. The drainage cylinder 4 is also a place where the upper end opening 5 is originally sealed with a not-shown gutter (cap) through a supporting rib so as to cover a water passage portion. In the lower end of the main body 1 a, a portion corresponding to the drainage cylinder 4 is provided with a drainage pipe connection port 7, and a drainage pipe 8 extending downward is connected to the connection port 7. On the other hand, a flange that protrudes outward is formed in a stepped shape on the upper end of the main body 1a, and an eye plate receiving portion 11 having a predetermined width is provided around the inside, and a drainage eye plate 13 is provided here. It is set and supported in a mounting form. The main body 1a itself is not different from the main body of the conventional trapezoidal trap.

  On the other hand, with respect to the upper end 5a of the drain tube 4 standing at the center of the bottom 3 of the main body 1a, a drain trap float having a size capable of closing the upper end opening 5 (hereinafter simply referred to as a float). 21) is arranged in a mounting manner. The float 21 is made of, for example, a resin and is hollow. When the drainage is not performed, the float 21 closes the upper end opening 5 by its own weight, and when the drainage is performed, the float 21 is lifted by buoyancy due to the drainage. And the upper end opening 5 is opened to allow drainage. However, in this embodiment, the float 21 has a circular short cylindrical shape in plan view whose outer diameter is slightly smaller than the inner diameter of the main body 1a, and its outer peripheral surface 23 is the trap main body (hereinafter also referred to as main body) 1a. It is formed so as to hold a slight gap in the radial direction so as to move up and down while being guided by the inner peripheral surface 9. This gap may be set to an appropriate size so that the float 21 is guided by the inner peripheral surface 9 and smoothly moves up and down.

  In addition, the float 21 has an appropriate number of through-holes 25 penetrating vertically as a water passage in a portion located outside the upper end opening 5 of the drain tube 4 in a plan view (see FIG. 2) along the circumferential direction ( 12 are opened), and the space K1 above the float 21 and the space K2 outside the drain tube 4 are formed to be continuous. The float 21 has a lower surface 26 formed as a flat surface and an upper surface 27 formed into a spherical shape. In addition, when the float 21 is placed on the upper end 5a of the drain tube 4 in the main body 1a, an appropriate space (height) is provided between the upper surface 27 of the float 21 and the lower surface of the eye plate 13. Is set to be secured. In other words, even when the drainage is performed and the float 21 is lifted by buoyancy, the height dimension is set so that the float 21 does not rise too much and pushes up the eye plate 13. In order to prevent such push-up, the drain pan 13 may be fixed to the trap body 1a side by screwing or the like on the outer periphery thereof.

  Thus, when drainage flows from the floor F through the drainage pan 13 into the drainage trap 1 of the present embodiment, the drainage from the upper space K1 of the float 21 mainly through the through hole 25 of the float 21 and the drainage cylinder. 4 to the outer space K2. However, the waste water accepted at the time of previous drainage remains in this space K2. Therefore, as shown in FIG. 3, the float 21 is floated (moved upward) by the drainage that continuously flows from the floor F, and the drainage of the drainage cylinder 4 overflows at the upper end 5 a of the drainage cylinder 4. It flows into the drain tube 4 from the upper end opening 5 and is discharged to the outside through the drain pipe 8. The broken line arrows in FIG. 3 indicate the flow of drainage. When the float 21 is floated, the outer peripheral surface 23 of the float 21 is guided by the inner peripheral surface 9 of the main body 1a. At the end of drainage, the float 21 is similarly guided by its own weight, and is placed on the upper end 5 a of the drainage cylinder 4 to close the upper end opening 5. That is, the float 21 does not require any special member or configuration, and can move stably without greatly changing the planar position or posture in its vertical movement.

  As described above, the drain trap 1 according to the present embodiment is a float trap. However, since a separate member (part) is not required as a guide when the float 21 is moved up and down, the number of parts constituting the trap 1 is increased. Neither does it complicate the structure. Therefore, since there is little risk of malfunction occurring in the operation, there is an effect that stable drainage is performed.

  Moreover, in the float 21 of the said form, although the case where the several independent through-hole 25 was provided as a water flow path where the space K above it and the space K2 outside the drain tube 4 continue was illustrated, this water flow path is As shown in FIG. 4, a plurality of cut-out concave portions 29 may be provided on the outer peripheral surface 23 of the float 21 so as to extend vertically. Furthermore, the float 21 may have a polygonal shape such as a quadrangle in a plan view as shown by a two-dot chain line in FIG. In this case, each corner 30 on the outer peripheral surface of the polygon in plan view is formed so as to move up and down while being guided by the inner peripheral surface of the trap body 1a, and between the corners 30 of the float 21 in plan view. A water passage that connects the space above the float 21 and the space outside the drainage cylinder 5 is formed in the outer part of the side portion. Thus, the planar shape of the float 21 can be set appropriately. The same applies to the shape of the inner peripheral surface of the trap body 1a. In other words, in the present invention, the float 21 is formed such that its outer peripheral surface 23 moves up and down while being guided by the inner peripheral surface 9 of the trap body 1a, and the float 21 is formed outside the upper end opening 5 in plan view. What is necessary is just to form the water passage which connects the space K1 above the float 21 and the space K2 outside the drainage cylinder 4 in the site | part which is located, and it is not restrict | limited to the shape of the main body 1a and the float 21.

  Next, the drain trap according to claim 2 will be described. The drain trap 1 described above is embodied in a type in which the drain pan 13 is set directly in the upper opening of the main body 1a. However, as shown in FIG. 13 is supported by a ring-shaped eye plate receiving frame 31, and the eye plate receiving frame 31 and the main body 1a are connected to each other by a connecting pipe (pipe) 35 provided concentrically at the upper part in the trap main body 1a. There is a trap 1 configured to be connected so that the height of the tray receiving frame 31 can be adjusted. Since the trap 1 shown in FIG. 5 has the same configuration as that of FIG. 1 except for such a configuration, the same portions are denoted by the same reference numerals, and the description thereof is omitted. That is, in this case, while a screw is formed on the outer peripheral surface of the connecting pipe 35, a screw corresponding to the screw is provided on the lower inner periphery of the eyepiece receiving frame 31 and the upper inner periphery of the main body 1a. It is formed and the construction height of the eye plate receiving frame 31 is adjusted by screwing with the screw. In the drain trap 1 having such a structure, when the connecting pipe body 35 is located on the outer periphery of the float 21, the float 21 moves up and down with its outer peripheral surface 23 guided by the inner peripheral surface 9 of the trap body 1a. If the outer peripheral surface 23 of the float 21 is formed so as to move up and down by being guided by the inner periphery 39 of the connecting tube 35 provided concentrically at the upper part in the trap body 1a. Good. In the trap shown in FIG. 5, the present invention can be embodied in the same manner even when the connecting pipe body (pipe) 35 is integrally provided with the eyepiece receiving frame 31 on the upper part thereof.

  Further, as is apparent from the above, the float 21 described above is extremely convenient because it can be used in place of the damaged ridge in the existing drain trap. That is, the float 21 does not require a separate part for guide, and can be mounted simply by placing it on the drain tube of the existing trap body. It is extremely effective as a countermeasure against the usage pattern that is used in the absence of wrinkles. Note that the planar shape of the float 21 used as such a trap can also be set appropriately.

  Next, an embodiment of the trap according to claim 3 of the present invention will be described with reference to FIGS. However, this embodiment is different from the embodiment shown in FIG. 1 only in the float 21, and therefore, the same portions are only given the same reference numerals, and the difference will be mainly described. That is, in this embodiment, the float 21 has a smaller outer diameter than that of the above-described embodiment. That is, the outer diameter is only slightly larger than the outer diameter of the upper end 5a of the drain tube 4 on which it is placed, and is between the outer peripheral surface 23 of the float 21 and the inner peripheral surface 9 of the main body 1a. Has a sufficient drainage channel (cross-sectional area). On the other hand, a guide portion 28 is integrally formed at the lower center of the float 21 so as to be inserted into the drainage cylinder 4 and serve as a guide when the float 21 moves up and down. As shown in FIG. 7, for example, the guide portion 28 has a cross shape as shown in FIG. 7, and a water passage in the drain tube 4 is secured. The guide portion 28 can be embodied as an appropriate shape and structure as long as a water passage in the drain tube 4 is secured.

  Also in this embodiment, as shown in FIG. 8, the float 21 is floated (moved up) by the drainage that continuously flows from the floor F, and overflows at the upper end 5 a of the drainage tube 4. It flows from the upper end opening 5 into the drain tube 4, passes through the drain pipe 8, and is discharged to the outside. The broken line arrow in FIG. 8 shows the flow of drainage. When the float 21 is floated, the lower guide portion 28 of the float 21 is guided to the inner peripheral surface 9 of the drain tube 4. At the end of drainage, the float 21 is similarly guided by its own weight, and is placed on the upper end 5 a of the drainage cylinder 4 to close the upper end opening 5.

  As described above, the drain trap 1 of the present embodiment is also of a floating type open / close type, but the number of parts constituting the trap 1 is not increased and the structure thereof is not complicated. Also, such a float 21 is very convenient because it can be used in place of a broken ridge in an existing drain trap. Moreover, since the inner diameter of the drain tube 4 in the trap body 1a is generally the same as the inner diameter of the drain pipe 8, the outer diameter dimension of the guide portion 28 is set slightly smaller than this dimension. Can be shared with many traps.

  As shown in FIG. 9, in the trap 1 of the form shown in FIG. 1, a guide that is inserted into the drain tube 4 at the lower center of the float 21 and serves as a guide when the float 21 moves up and down. The part 28 may be integrally formed. In this way, the float 21 can move more stably up and down. Further, the float 21 shown in FIG.

  The drain trap and float of the present invention are not limited to the above-described forms, and can be embodied with various design changes without departing from the gist thereof. For example, the float is not hollow and may be made of polystyrene foam, and the material thereof can be embodied as appropriate. The trap is not limited to a floor drain trap.
