Description

  The present invention relates to a protective member for high pressure cleaning used for high pressure cleaning of a drain pipe using a cleaning hose and a high pressure cleaning method using the same.

  For example, a sink main body is formed in the sink of a kitchen, and a drain pipe is connected to a connection opening that opens to the drain main body, but the rise of odor from the pipe is between the connection opening and the drain pipe. A trap to prevent this is connected.

  Here, the trap is arranged in the cabinet below the sink, and there are belt wraps, S-shaped traps, and the like. When a cylindrical belt wrap is adopted, the belt wrap is placed in the cabinet. Since this occupies a large space, the storage space in the cabinet is limited.

  Therefore, a configuration is adopted in which a flat S-shaped trap is adopted as a deodorizing means, and this S-shaped trap is arranged on the back side of the cabinet to secure a large storage space in the cabinet.

  By the way, in an apartment house such as an apartment, for example, high-pressure cleaning of a drain pipe connected to an S-shaped trap is regularly performed. Conventionally, this high-pressure cleaning is performed by opening a cabinet and performing an S-shaped trap in the cabinet. Since it was necessary to insert a washing hose into the drain pipe after removing the drain pipe, there was a problem that the work was difficult and the efficiency was poor.

  Therefore, a cleaning method that can perform high-pressure cleaning of the drain pipe without removing the trap or the drain pipe has been proposed (see, for example, Patent Document 1).

  Here, an example of a conventional high-pressure cleaning method for a drain pipe will be described with reference to FIG.

  FIG. 8 is a side cross-sectional view of an S-shaped trap portion showing a conventional high-pressure cleaning method. In FIG. 8, reference numeral 113 denotes a concave drain body formed in a sink of a system kitchen (not shown). A circular drainage port 114 and a hose insertion port 115 are opened in the main body 113. An S-shaped trap 118 is connected to the drain port 114 and the hose insertion port 115 via adapters 116 and 117.

  Here, the S-shaped trap 118 has a S-shape when viewed from the front, and the two openings 118a and 118b opened upward are inserted into the drain port 114 and the hose through the adapters 116 and 117, respectively. A drainage pipe 119 is connected to the opening 118 c that is connected to each of the ports 115 and opens downward.

  Further, the S-shaped trap 118 is provided with a U-shaped sealing portion 118d and a bypass portion 118e for bypassing the sealing portion 118d and connecting the hose insertion port 115 to the drain pipe 119. ing. A drain hole 118f is formed in the lower portion of the water sealing portion 118d, and a drain bolt 120 is screwed into the drain hole 118f. Note that the eye plate 121 is screwed into the drain port 114, and a cap (not shown) is attached to the hose insertion port 115 except when the drain pipe 119 is washed at high pressure.

Thus, when high-pressure washing is performed on the drain pipe 119 and the pipe portion beyond the drain pipe 119, a cap (not shown) attached to the hose insertion port 115 is removed to open the hose insertion port 115, and the hose insertion port 115 is opened. Then, the cleaning hose 122 is inserted into the S-shaped trap 118, and the cleaning hose 122 is introduced from the bypass part 118e of the S-shaped trap 118 to the drain pipe 119 as shown in the figure, and from the injection nozzle 124 attached to the tip thereof. The high-pressure water is jetted to clean the drain pipe 119 and the piping part ahead.

  However, as shown in FIG. 8, when the cleaning hose 122 is taken in and out of the drain pipe 119 and the pipe portion ahead thereof through the S-shaped trap 118, the cleaning hose 122 is a part of the bypass portion 118 e (illustrated). There is a problem that the cleaning operation cannot be performed smoothly and efficiently because the frictional resistance increases due to contact and rubbing. In particular, when the diameter of the hose insertion port 115 or the bypass part 118e is small, or the bend of the bypass part 118e is abrupt, the number of parts that come into contact with the cleaning hose 122 increases, and the frictional resistance due to the contact increases, resulting in a cleaning hose. It becomes increasingly difficult to put in and out 122.

  The present invention has been made in view of the above problems, and the object of the present invention is that the washing hose can be smoothly inserted and removed without resistance, and the high pressure washing of the drain pipe can be efficiently performed with good efficiency by the washing hose. An object of the present invention is to provide a protective member for high-pressure cleaning that can be performed and a high-pressure cleaning method for a drain pipe using the same.

  According to a second aspect of the present invention, the high pressure cleaning protection member according to the first aspect can be deformed along the shape of the bypass portion of the S-shaped trap, and the cleaning hose is inserted into the guide to guide the same. It is characterized by comprising a flexible tube.

  According to a third aspect of the present invention, the high pressure cleaning protective member according to the first aspect is constituted by a rigid member having a guide portion formed in a shape along the bypass portion of the S-shaped trap.

  The invention described in claim 4 is characterized in that the high-pressure cleaning protective member according to any one of claims 1 to 3 is provided with a flange having an outer diameter larger than the diameter of the hose insertion port.

  The invention according to claim 5 is connected to a drain opening and a hose insertion opening that are open in the drain opening main body, and includes a sealing portion and a bypass portion that bypasses the sealing portion and connects the hose insertion port to the drain pipe. A drainage pipe connected to an S-shaped trap is equipped with a high-pressure washing method, wherein a washing hose is inserted into the S-shaped trap from the hose insertion port, and the washing hose is introduced into the drainage pipe through the bypass portion. A high-pressure cleaning method for high-pressure cleaning the drain pipe, wherein the high-pressure cleaning protection member according to any one of claims 1 to 4 is attached to the hose insertion port, and the cleaning hose is guided by the high-pressure cleaning protection member. Then, it is introduced into the drain pipe through the bypass portion.

  According to the high-pressure cleaning method according to claim 5, which is carried out using the protective member for high-pressure cleaning according to any one of claims 1 to 4, the high-pressure cleaning is performed in the high-pressure cleaning of the drain pipe and the pipe portion ahead thereof. Since a protective hose is attached to the hose insertion port, the cleaning hose inserted into the S-shaped trap from the hose insertion port is guided by the high pressure cleaning protective member and introduced into the drain pipe through the bypass portion. When the hose is taken in and out, the washing hose does not come into contact with the bypass portion and the like, and the washing hose can be taken in and out smoothly without resistance. As a result, the high-pressure water sprayed from the tip of the cleaning hose can efficiently and efficiently perform high-pressure cleaning of the drain pipe and the pipe portion ahead.

  Also, since the high pressure cleaning protective member is provided with a hook having an outer diameter larger than the diameter of the hose insertion port, the hook functions as a stopper, and the high pressure cleaning protective member falls into the S-shaped trap during the cleaning operation. And other problems do not occur.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

<Embodiment 1>
FIG. 1 is a perspective view of a system kitchen, and FIG. 2 is a side sectional view of an S-shaped trap portion showing a high pressure cleaning protection member and a high pressure cleaning method using the same according to Embodiment 1 of the present invention.

  A top plate 2 made of, for example, artificial marble is installed on the upper surface of a rectangular box-shaped main body 1 of the system kitchen shown in FIG. 1, and the right half of the top plate 2 is made of stainless steel that is long in the lateral direction. The concave sink 3 is embedded, and a gas table 4 is installed on the left side.

  A cabinet 5 (see FIG. 2) as a storage space is formed below the sink 3 and the gas table 4 of the main body 1, and an opening / closing door 6, a drawer 7, 8, 9, 10, 11, and 12 are sequentially provided.

  By the way, a drain port body 13 having a circular recess is formed on the back side in the center of the sink 3 in the width direction. The drain port body 13 has a front side (right side in FIG. 2) and a back side ( On the left side of FIG. 2, a circular drain port 14 and a hose insertion port 15 having large and small diameters are opened. As shown in FIG. 2, an S-shaped trap 18 is connected to the drain port 14 and the hose insertion port 15 through adapters 16 and 17.

  Here, as shown in FIG. 2, the S-shaped trap 18 has a horizontal S-shape as viewed from the front, and the two openings 18 a and 18 b that open upward are formed through the adapters 16 and 17. A drain pipe 19 is connected to an opening 18c that is connected to the drain port 14 and the hose insertion port 15 and opens downward.

  The S-shaped trap 18 has a U-shaped sealing portion 18d and a bypass portion 18e for bypassing the sealing portion 18d and connecting the hose insertion port 15 to the drain pipe 19 on the rear side. It inclines in the diagonally downward direction toward. A drain hole 18f is formed in the lower portion of the water sealing portion 18d, and a drain bolt 20 is screwed into the drain hole 18f. Note that the eye plate 21 is screwed to the drain port 14, and a cap (not shown) is attached to the hose insertion port 15 except during high-pressure washing of the drain pipe 19.

  In the above, in a normal use state in which the drain pipe 19 and the pipe portion ahead thereof are not cleaned, the hose insertion port 15 is sealed with a cap (not shown), and the water used in the sink 3 of the system kitchen is used. Flows from the eye plate 21 to the drain port 14, through the S-shaped trap 18 to the drain pipe 19. At this time, since water is accumulated in the sealed portion 18d of the S-shaped trap 18, the odor rising from the drain pipe 19 is blocked by the water accumulated in the sealed portion 18d, and the odor is transferred from the drain port 14 to the sink 3 side. And there is no leakage. Since the hose insertion port 15 is covered with a cap (not shown) as described above, the odor rising from the drain pipe 19 through the bypass portion 18e is blocked by the cap (not shown), and the odor is blocked by the hose insertion port. No leakage from 15 to the sink 3 side.

  Thus, when high-pressure washing is performed on the drain pipe 19 and the pipe portion beyond the drain pipe 19, the cap (not shown) attached to the hose insertion port 15 is removed to open the hose insertion port 15, and the hose insertion port 15 is opened. The cleaning hose 22 is inserted into the S-shaped trap 18, and a protective tube 30 as a high pressure cleaning protection member according to the present invention is passed through the cleaning hose 22 in advance.

  The protective tube 30 is detachable from the hose insertion port 15 and is composed of a short tube made of metal, resin, or rubber, and a cleaning hose 22 is passed through the inner portion of the protective tube 30. Constitutes a guide part for guiding the cleaning hose 22. A flange 30a having an outer diameter larger than the diameter of the hose insertion port 15 is integrally formed on the outer periphery of the upper portion of the protective tube 30, and the groove formed in the flange 30a includes A packing 23 such as an O-ring made of a soft material is fitted.

The cleaning hose 22 inserted into the inside is guided by the protective pipe 30 and introduced into the drain pipe 19. Since the soft packing 23 is fitted on the flange 30a of the protective tube 30, direct contact between the protective tube 30 and the hose insertion port 15 is avoided by the packing 23, and is formed on the inner periphery of the hose insertion port 15. Damage to the threaded portion is prevented.

  Thus, when the cleaning hose 22 inserted from the hose insertion port 15 as described above is guided by the protective tube 30 and introduced into the drainpipe 19, the drainpipe 19 and the pipe portion ahead thereof are connected to the cleaning hose. The high pressure water is jetted from the jet nozzle 24 attached to the tip of the nozzle 22. In this case, since the flange 30a formed on the protective tube 30 functions as a stopper, the protective tube 30 does not cause problems such as dropping into the S-shaped trap 18.

  When the high-pressure cleaning of the drain pipe 19 and the pipe portion ahead of the drain pipe 19 is completed, the cleaning hose 22 is pulled out from the drain pipe 19 and the pipe portion ahead of the drain pipe and the S-shaped trap 18. If the hand is held by hand, there is no problem that the protective tube 30 comes off together with the cleaning hose 22 from the hose insertion port 15 and comes off.

  As described above, according to the high pressure cleaning method performed using the protective tube 30 according to the present embodiment, the cleaning hose 22 inserted into the S-shaped trap 18 from the hose insertion port 15 is guided by the protective tube 30. Since the cleaning hose 22 is introduced into the drain pipe 19 through the bypass portion 18e, the cleaning hose 22 does not come into contact with the bypass portion 18e and the like when the cleaning hose 22 is put in and out. It can be done smoothly. As a result, the high-pressure water sprayed from the spray nozzle 24 at the end of the cleaning hose 22 can efficiently and efficiently clean the drain pipe 19 and the pipe portion ahead thereof with high workability.
