  However, according to the telescopic connection drain pipe provided with the bellows of the elevator of such a conventional example, the telescopic drain pipe is covered with the bellows pipe in a state where its periphery is sealed, so the bellows pipe and the telescopic type The sealed air between the drain pipe and the bellows pipe may act like a kind of air spring, which may hinder smooth expansion and contraction of the drain pipe, that is, smooth raising and lowering of the toilet.

  And in the structure of the telescopic connection drain pipe provided with the bellows of this conventional example, since a certain volume of air with odor is sealed between the bellows and the telescopic connection drain pipe, By repeatedly raising and lowering the pressure, the pressure in the space repeatedly rises and falls, and the generation of stress in the bellows tube accompanying the pressure rise and the elastic deformation of the bellows tube that repeats along with expansion and contraction combine with the bellows tube. There is a risk of cracks and tearing, and the strange odor in the bellows can spread all at once in the toilet.

  An object of the present invention is to provide a telescopic drainage pipe structure for a lift toilet that raises and lowers the toilet smoothly and does not generate odor in the toilet when the toilet is lifted.

In order to solve the problems described above, the telescopic drainage pipe structure of the lifting toilet according to the present invention is:
A telescopic connecting drain pipe structure of a lifting / lowering toilet comprising a frame attached to a floor or wall of a toilet and a toilet that moves up and down along the frame,
The connection drain pipe is used when connecting the toilet drain pipe and the floor drain pipe,

A part of the area defined by the connection drain pipe and the bellows pipe is provided with an intake / exhaust port from the area to the floor drain pipe.

  The drain pipe structure of the lifting / lowering toilet according to the present invention has such a configuration, so that the periphery of the telescopic drain pipe is sealed like the telescopic connection drain pipe provided with the bellows of the conventional lifting / lowering toilet. It does not have to be covered with a bellows tube. For this reason, the air sealed between the bellows pipe and the telescopic drainage pipe is like a kind of air spring in combination with the bellows pipe like the telescopic connection drainage pipe with the bellows of the conventional elevator. The drain pipe can be smoothly expanded and contracted, that is, the toilet can be lifted and lowered smoothly.

  In addition, by repeatedly raising and lowering the toilet many times like a telescopic connection drain pipe provided with the bellows of a conventional elevator, the pressure in the space is repeatedly increased and decreased, and the stress of the bellows tube accompanying the pressure increase is increased. Combined with the occurrence and the elastic deformation of the bellows tube that is repeated along with expansion and contraction, the bellows tube is cracked and broken, so that it is not necessary to cause a problem that a strange smell in the bellows tube diffuses into the toilet at once.

  According to the present invention, it is possible to provide a telescopic drainage pipe structure for an elevator toilet that raises and lowers the toilet smoothly and does not generate odor in the toilet when the toilet is raised or lowered.

The state in which the motor 61 is driven and controlled so that the toilet 10 is positioned at the lower end of the fixed frame 31 is shown.

  The base plate 20 that supports the fixed frame 31 is made of a steel plate. As shown in FIG. 1, the base plates 21 and 22 face the front of the toilet 10 from the lower ends of the two fixed frames 31 of the toilet fixed frame 30. Each extends slightly beyond the toilet bowl 10. The base plate 20 forms a toilet floor surface in combination with, for example, a panel recess (not shown in FIG. 1) having an elongated notch into which the base plate 20 is fitted.

  The drainage pipe 100 of the lifting / lowering toilet 1 includes a telescopic connection drainage pipe 110 that connects the toilet side drainage pipe 101 fixed to the toilet bowl side and the floor side drainage pipe 90, and is connected to the lower end of the connection drainage pipe 110. A plug socket 200 is provided. The connection drain pipe 110 is a telescope type drain pipe, and includes a bellows pipe 120 that covers the periphery of the connection drain pipe 110 and expands and contracts in accordance with the expansion and contraction of the connection drain pipe 110.

  Further, a plug socket 200 is provided at the floor side end of the connection drain pipe 110. And the clearance gap between the opening part for insertion provided in the toilet floor by the plug socket 200 and the floor side drain pipe 90 mentioned above is covered.

  The toilet-side drain pipe 101 is made of rubber, such as a PVC pipe that has elasticity and has a certain degree of softness and can withstand drainage of cleaning liquid, and has an L-shape when viewed from the side of the toilet bowl. One end is connected to the drain opening on the back of the toilet bowl, and the other end is connected to the upper part of the connection drain pipe 110. Even if the distance between the fixing position of the plug socket and the end of the toilet drain pipe becomes longer or shorter than the specified distance due to the placement error of the plug socket and frame during construction, etc., the toilet drain pipe By having the elasticity of 101 and the toilet drainage pipe 101 having the bellows part 101a, errors can be absorbed by the bellows part 101a, and without connecting the drainage pipes 111 and 112 to be inclined, The center can be arranged in the vertical direction, and the toilet can be raised and lowered smoothly.

  The connection drain pipe 110 is formed of a telescope type drain pipe as described above, and has two cylindrical pipes 111 and 112 connected vertically as shown in FIG. 6, and the outer diameter of the upper cylindrical pipe 111 is a lower cylinder. The upper cylindrical tube 111 protrudes from the lower cylindrical tube 112 when the toilet is raised, and the upper cylindrical tube 111 enters the lower cylindrical tube 112 when the toilet is lowered. The upper cylindrical tube 111 and the lower cylindrical tube 112 are both made of a polyvinyl chloride tube or the like that is hard and has sufficient strength and chemical resistance that can withstand the drainage of the cleaning liquid.

  Further, the upper end portion 111a of the upper cylindrical tube 111 is covered with the end portion of the toilet-side drainage pipe 101, and the periphery of this end portion is firmly fastened by an insulok lock 141. It is designed not to leak outside.

  In addition, a packing 113 is interposed between the upper cylindrical tube 111 and the lower cylindrical tube 112 so as to prevent sewage in the connection drainage pipe from leaking between the upper cylindrical tube 111 and the lower cylindrical tube 112 to the outside as much as possible. ing. Further, the upper end portion 112a of the lower cylindrical tube 112 is a stopper, which prevents the connecting drain tube 112 from coming out of the plug socket 200 when the toilet is lowered. In addition, even when the floor drain pipe (house side drain pipe) has a bent portion directly under the floor and is disposed horizontally under the floor, the connecting drain pipe 112 protrudes under the floor when the toilet is lowered using the stopper 112a. By limiting the dimensions to be performed, it is possible to prevent the connection drain pipe 112 from interfering with the bent part of the floor drain pipe when the toilet is lowered.

  The plug socket 200 is made of hard vinyl chloride or the like having sufficient strength, excellent moldability, and chemical resistance that can withstand the drainage of the cleaning liquid, and is rectangular in plan view as shown in FIGS. The base plate 210 and a cylindrical socket body 220 having an opening projecting upward from the base plate 210 and having a reduced diameter at the upper end. And the attachment hole 211 which lets through fasteners, such as a volt | bolt for attaching the plug socket 200 to the toilet floor F, is formed in the four corners of the base board 210. FIG.

  Further, the periphery of the opening portion of the upper surface 220 a of the socket body 220 protrudes and this portion forms a connection portion 222 with the connection drain pipe 110. The inner diameter of the connecting portion 222 has an inner diameter that is substantially equal to the outer diameter of the lower cylindrical tube 112 of the connecting drainage pipe 110, whereby the lower cylindrical tube 112 of the connecting drainage pipe 110 is connected to the connecting portion 222. It is designed to slide smoothly. The outer diameter of the lower end 112b of the lower cylindrical pipe 112 of the connection drain pipe 110 is slightly larger than the inner diameter of the connection part 222 of the plug socket 200, and this part serves as a stopper. When the lower cylindrical pipe 112 of the connection drain pipe 110 extends upward, the plug socket 200 is prevented from coming off.

  In the present embodiment, eight ribs 225 extend radially from the upper surface 220a of the socket main body 200 at a distance from the connecting portion 222 in the circumferential direction. The rib 225 serves to prevent the bellows tube 120 from closing the intake / exhaust port 223 of the socket body 220, which will be described later, when the bellows tube 120 contracts, but also functions as a reinforcing rib of the plug socket 200. Have.

  In the upper surface 220 a of the socket body 220, a suction pipe that communicates the upper surface of the socket body 220 and the inside of the floor-side drain pipe 90 connected to the inside of the socket body 220 is located at a substantially middle position in the connecting portion circumferential direction of the adjacent rib 225. In the present embodiment, a total of eight exhaust ports 223 are provided.

  The intake / exhaust port 223 draws air into the space defined by the connection drainage pipe 110 and the bellows pipe 120 from the inside of the floor side drainage pipe when the toilet 10 rises and the connection drainage pipe 110 extends. 120 also extends without resistance. In addition, the air intake / exhaust port 223 exhausts the space defined by the connection drain pipe 110 and the bellows pipe 120 into the floor side drain pipe 90 when the elevator 10 descends and the connection drain pipe 110 contracts. Then, the bellows tube 120 is also shrunk without resistance.

  Note that the upper surface of the socket body 220 has an inclined surface 224 that is slightly inclined downward from the outer peripheral edge toward the connection portion. If the lower end portion of the connection drain pipe 110 is clogged with dirt, Is filled with water, and when the sewage leaks from the connection portion of the upper cylindrical pipe 111 and the lower cylindrical pipe 112 of the connection drain pipe 110, the sewage is drained through the inclined surface 224 and the intake / exhaust port 223. It plays the role of returning to the tube 90.

  As shown in the cross-sectional view of FIG. 9, the plug socket 200 is provided with an inner peripheral wall 240 inside the outer peripheral wall 230 of the socket body 220 at a predetermined interval over the entire circumferential direction. The above-described intake / exhaust port 223 is formed between the portion where the inner peripheral wall 240 on the upper surface of the socket body 220 extends and the connection portion 222 protruding upward on the inner side, and is formed on the connection portion 222 side. Yes.

  Since the predetermined gap is thus formed in the circumferential direction between the outer peripheral wall 230 and the inner peripheral wall 240, the large-diameter floor side drain pipe 91 is connected to the plug socket 200 as shown in FIG. If the outer peripheral surface of the floor-side drain pipe 91 is in contact with and connected to the inner peripheral surface of the outer peripheral wall 230, and the small-diameter floor-side drain pipe 92 is connected to the plug socket 200, the inner peripheral wall 240 is used. The outer peripheral surface of the floor side drain pipe 92 is in contact with and connected to the inner peripheral surface of the floor. When connecting the small-diameter floor side drain pipe 92 to the pipe socket, the inlet / outlet port 223 is plugged in such a dimension that the upper end of the floor side drain pipe 92 does not block the inlet / outlet port 223 of the pipe socket 200. It is formed in the socket 200 (refer to the positional relationship between the floor-side drain pipe 92 and the intake / exhaust port 223 indicated by a two-dot chain line in FIG. 9).

  As shown in FIGS. 6 and 9, the outer peripheral wall 230 of the plug socket 200 is covered with the lower end of the bellows tube 120 on the upper portion thereof, and the lower end of the bellows tube 120 and the outer peripheral wall 230 of the plug socket 200 are connected via an insulation lock 144. Both of them are kept in close contact with each other so that odors and sewage are not leaked out.

  The bellows tube 120 is made of a material having excellent elasticity such as soft vinyl chloride, and the upper end portion thereof is connected to the connecting portion between the upper cylindrical body 111 and the toilet-side drain tube 101 via an insulation lock 143. The lower end portion of the plug socket 200 is covered with the socket body 220 of the plug socket 200, and the socket body is secured with the insulation lock 144 as described above. It is designed to be connected in a state where it is firmly attached to the.

  Then, the effect | action of the expansion-contraction type drain pipe structure of the raising / lowering toilet 1 in embodiment mentioned above is demonstrated.

  After installing the wall-mounted toilet 1 in the toilet, the user pushes the lift button 81 of the lift switch 80 shown in FIG. 10 to raise the toilet 10 to above the toilet fixing frame 30. Thus, the user can sit comfortably with a feeling of sitting without excessive bending when sitting on the toilet seat 40.

  When the toilet 10 is raised from the lower limit position in accordance with this toilet raising operation, the air in the floor side drainage pipe 90 passes between the connection drainage pipe 110 and the bellows pipe 120 via the intake / exhaust port 223 of the plug socket 200. Inhaled into space. Thereby, it does not become a state covered with the bellows tube in a state where the periphery is sealed like the telescopic drainage tube in the bellows type drainage tube of the conventional elevator, but the telescopic drainage tube and the bellows tube The air sealed between them does not act like a kind of air spring in combination with the bellows tube, and the telescopic drainage tube 100 can be smoothly extended to realize a smooth ascending operation of the toilet 10. .

  Then, the user presses the lowering button 82 of the elevating switch 80 to lower the toilet 10 to the lower side of the toilet fixing frame 30 shown in FIG. 8, adds the use, and then presses the rising button 81 again to raise the toilet 10 and raise the toilet seat. From 40, you can stand up comfortably without bending your waist.

  When the toilet 10 is lowered from the upper limit position in accordance with the toilet lowering operation, the air in the space between the connection drain pipe 110 and the bellows pipe 120 is sucked into the floor side drain pipe 90 via the intake / exhaust port 223 of the plug socket 200. Exhausted inside. As a result, the telescopic drainage pipe 100 and the bellows pipe are not covered with the bellows pipe 120 in a state in which the periphery thereof is sealed like the telescopic drainage pipe in the bellows type drainage pipe of the conventional elevator. The air sealed with 120 does not act like a kind of air spring in combination with the elastic force of the bellows tube 120, and the telescopic drainage tube 100 is smoothly contracted and the toilet 10 is smoothly lowered. Operation can be realized.

  In addition, if sewage flows when the toilet is raised, the sewage adheres to the inner surface of the connection drainpipe 112. Therefore, when the toilet is lowered, the sewage adhered to the inner surface of the connection drainpipe 111 comes into contact with the outer periphery of the connection drainpipe 111. Next, when the toilet is raised again, the connecting drainpipe 111 having sewage adhered to the outer periphery protrudes from the connecting drainpipe 112, and the telescopic drainpipe 100 and the bellows pipe 120 are connected from the connecting part of the telescopic drainpipe 100. The air in the sealed space between them gives off a strange odor, but when the toilet is lowered, the telescopic drainage pipe 100 and the bellows pipe 120 are contracted together, so that the floor side drainage from the intake / exhaust port 223 of the plug socket 200 is performed. Since it is exhausted to the tube 90, no off-flavor will drift in the toilet.

  Further, since eight ribs 225 are formed on the upper surface 220a of the socket body 220 so as to extend radially from the connection portion 222 at intervals in the circumferential direction, when the bellows tube 120 is completely contracted. In addition, the bellows tube 120 does not block the intake / exhaust port 223 of the socket body 220, and the function of the intake / exhaust port 223 is not impaired.

  Further, since the upper surface 220a of the socket body 220 has an inclined surface 224 that is slightly inclined downward from the outer peripheral edge toward the connection portion, the upper cylindrical tube 111 and the lower cylindrical tube 112 of the connection drain pipe 110 When the sewage leaks from the connecting portion of the socket, it is returned to the floor side drain pipe 90 via the intake / exhaust port 223. Odor can be prevented.

  Also, like the bellows type drainage pipe of a conventional example of a toilet bowl, the bellows pipe that is repeated along with the generation and expansion and contraction of the bellows pipe by repeatedly raising and lowering the pressure in the space by raising and lowering the toilet bowl many times. Combined with the elastic deformation, the bellows tube is cracked and broken, so that it does not cause a problem that a strange odor in the bellows tube diffuses into the toilet at once.

  As described above, the drainage pipe structure of the lifting / lowering toilet according to the present invention does not cover the telescopic drainage pipe with the bellows pipe in a state where its periphery is sealed like the bellows type drainage pipe of the conventional lifting / lowering toilet. As a result, the sealed air between the bellows pipe and the telescopic drain pipe can act like a kind of air spring in combination with the bellows pipe like the bellows drain pipe of the conventional elevator. The drain pipe can be smoothly expanded and contracted, that is, the toilet can be lifted and lowered smoothly.

  In addition, the drainage pipe structure of the lifting / lowering toilet according to the present invention is accompanied by the pressure increase by repeatedly raising and lowering the pressure in the space by raising and lowering the toilet many times like the bellows type drainage pipe of the conventional lifting / lowering toilet. The generation of stress in the bellows tube and the elastic deformation of the bellows tube that repeats with expansion and contraction combined with the cracks in the bellows tube, causing it to break down, causing a strange smell in the bellows tube to diffuse into the toilet at a stretch. You do n’t have to.

  In the embodiment of the present invention, the toilet bowl is provided with a low tank. However, the present invention can be applied to a toilet without a low tank but a water direct pressure toilet or a toilet equipped with a pump.

  Further, the connection drain pipes 111 and 112 introduced as telescope type drain pipes in the embodiment of the present invention may be integrated.

  Further, in the embodiment of the present invention, the toilet bowl having the toilet drainage pipe provided on the wall side has been described. However, the present invention is not limited thereto, and the toilet bowl may include a drainage section from the toilet bowl to the floor side. Further, each toilet described above may be directly connected to the connected drain pipe.
