The connection does not provide sufficient sealing. For this reason, the dirty odor from the drain pipe easily leaks from the gap portion of the cap mounting portion, which causes an unpleasant odor in the kitchen. Moreover, insects and the like also creep out from the gap, which is unsanitary. (B) For example, if the inner wall of the drainage pipe is contaminated with dirt and the inner diameter is thin, or if it is bent immediately from the connection with the connection hose and the hanging portion of the drainage pipe is short in the case of construction, etc. , The water pressure inside the connecting hose and drainage pipe tends to increase when drainage flows. However, as described above, the cap is simply fitted into the drain pipe. For this reason, in the worst case, there is a risk that the cap will come off and sewage will overflow into the kitchen.

【Example】

 The present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 is a perspective view of a kitchen sink according to the present invention, and FIG. 2 is a sectional view of an essential part showing the structure of a connecting portion of a connecting hose. Reference numeral A is a kitchen sink, which includes a sink body 1. Two hinged doors 10 are provided on the front surface of the sink body 1, and drawer storage portions 11 are provided next to it in four stages. A cooking table 12 made of stainless steel is provided on the sink body 1. A sink unit 13 is provided on one side of the cooking table 12. A drainage section 14 is provided in the bottom of the sink section 13 at approximately the center thereof. The drainage device 2 is attached to the drainage unit 14. The sink drainage device 2 includes a drainage device 21 and a connection hose 22. The drainage device 21 is detachably attached to the drainage portion 14 of the sink portion 13 via a mounting tool (not shown). The drainage device 21 includes a bottomed tubular drainage base 210. On the upper part of the drainage base 210, a rubber sealing plate 212 provided with cross cuts is attached. Below the sealing plate 212, a bottomed cylindrical dust separator 214 having a large number of small holes is detachably mounted. Further, a water-sealing type trap device 216 is housed in the inner bottom portion of the drainage base 210, and a connecting hose 22 is connected to a drainage cylinder 218 (shown in FIG. 2) which is a drainage part of the drainage base 210. .. The connection hose 22 has a flexible hose main body 220. The hose main body 220 includes a cylindrical skeleton body 220a formed by spirally forming an elastic plastic wire rod, and an outer peripheral portion of the cylindrical skeleton body 220a is made of a flexible synthetic resin hose sheet. It is covered with 220b. Further, the inner surface of the hose main body 220 is made substantially smooth, and the outer surface of the hose main body 220 is made to be an uneven surface in which the shape of the cylindrical skeleton body 220a is raised. As a result, the hose main body 220 is a bellows tube. A trap socket 223 connected to the drain tube 218 of the drainage device 2 is screwed to the base end of the hose main body 220. In addition, a drain pipe socket 225 connected to a drain pipe 5 described later is screwed to the tip of the hose main body 220. A male screw 224 adapted to the lead angle of the tubular body 220a is formed on the outer peripheral surface of the mounting tubular portion 222 provided on the base side of the trap socket 223. Further, a female screw 227 adapted to the lead angle of the tubular skeleton 220a is also formed on the inner peripheral surface of the mounting tubular portion 226 which is a mounting portion provided on the base side of the drain pipe socket 225. With this structure, the trap socket 223 and the drain pipe socket 225 are screwed to the hose main body 220 only by fitting and twisting them, and the screwed portions are closely attached. In the present embodiment, the means for mounting the trap socket 223 and the drain pipe socket 225 to the hose main body 220 is screwing, but the means is not limited to this, and as long as the degree of adhesion is sufficient, such as insertion bonding. Other known means may be used. The connecting hose 22 is bonded by fitting the trap socket 223 to the drain tube 218. Since the mounting cylinder portion 226 of the drain pipe socket 225 is externally fitted to the hose main body 220, no step portion is formed between the mounting cylinder portion 226 and the hose main body 220 to prevent water flow. The drain pipe socket 225 has an inner cylinder 228 and an outer cylinder 229 which are concentrically formed as a connecting portion. The inner cylinder 228 and the outer cylinder 229 are internally or externally connected to the drain pipes 5a, 5b, 5c having different calibers described later. In the present embodiment, the connection means of the drain pipe socket 225 to the drain pipe 5 (5a, 5b, 5c) is a plug-in type, but the connection means is not limited to this, and the adhesion such as plug-in adhesion or screwing If the above is sufficient, other known means may be used. Further, since the tip of the inner cylinder 228 is formed to project slightly from the tip of the outer cylinder 229, the tip of the inner cylinder 228 can be easily seen when it is attached to the drainage pipe 5, so that the work can be easily performed. (Operation) The operation of this embodiment will be described with reference to FIGS. 1 and 2. When connecting the connecting hose 22 provided in the sink drainage device 2 attached to the kitchen sink A to the drain pipe 5 that is provided upright from the floor of the installation part of the kitchen sink A, drain the drain pipe 5. The pipe socket 225 is connected to connect the drainage device 21 and the drainage pipe 5 in a water-permeable manner. The attachment portion of the hose main body 220 and the drain pipe socket 225 of the connection hose 2 and the connection portion of the drain pipe socket 225 and the drain pipe 5 are attached or connected with sufficient adhesion. Therefore, at the time of use, the inner side and the outer side of the hose main body 220 and the drain pipe 5 are in a hermetically sealed state, and have a watertight and airtight action. Since the connecting hose 22 has flexibility, it can be flexibly dealt with even if the standing position of the drainage pipe 5 and the position of the drainage device 21 are slightly deviated. The way of connecting the drain pipe socket 225 to the drain pipe 5 differs as follows depending on the diameter of the drain pipe 5 (5a, 5b, 5c). First, when the drainage pipe 5 is the drainage pipe 5a having a diameter of 50 mm, the outer peripheral surface of the inner cylinder 228 of the drainage pipe socket 225 is closely connected to the inner peripheral surface of the drainage pipe 5a. When the drainage pipe 5 is the drainage pipe 5b having a diameter of 65 mm, the inner peripheral surface of the outer cylinder 229 is closely attached to the outer peripheral surface of the drainage pipe 5b to be connected. When the drainage pipe 5 is the drainage pipe 5c having a diameter of 75 mm, the outer peripheral surface of the outer cylinder 229 is closely attached to the inner peripheral surface of the drainage pipe 5c to be connected. In this way, the drain pipe socket 225 can accommodate three types of drain pipes 5a, 5b, 5c having different connection pipe diameters. FIG. 3 is a perspective view of an essential part showing another embodiment of the drainage device for sink. The sink drainage device 2a according to the present embodiment is attached to the drainage part of the washbasin. The drainage device 21a of the sink drainage device 2a is a so-called S-trap pipe, a drainage plug 26 is detachably screwed to the bottom, and a connecting hose 22 is connected to the tip by an adhesive. There is. Further, a fitting 29 for fitting to the drain of the washbasin is provided above the drainage device 21a. Reference numeral 27 is a plug and 28 is a chain. Although not shown in FIG. 3, a drain pipe socket 225 is provided at the tip of the connection hose 22 as in the case of the connection hose 22 of the drainage device 2 described above. It has almost the same action as the drainage device 2 such as prevention. Depending on the construction conditions, such as when the drainage direction is horizontal, the P trap pipe can be used as a drainage device. The present invention is not limited to the illustrated embodiment, but various modifications can be made within the scope of the claims for utility model registration.
