Detailed Description

For a better understanding of the objects, structure and function of the invention, reference should be made to the drawings, FIGS. 1-3, which are included to illustrate the invention.

As shown in fig. 1-2, a sealing connection assembly is designed, which comprises a tapered tube 6 communicated with the end of a first pipeline and a sleeve 8 communicated with the end of a second pipeline, wherein an elastic sealing ring 7 is sleeved on the tapered tube 6, the tapered tube 6 is inserted into the sleeve 8, and the sealing ring 7 is fixedly connected with the side wall of the sleeve 8. Will the utility model provides a sealing connection group is used in prior art's dish washer, explains as the embodiment, and its dish washer's structure mainly includes dish washer's shell 4, and installs inner bag 2, interior door 3 and connecting pipe 5 in the shell 4, realizes connecting through foretell sealing connection subassembly between connecting pipe 5 and the interior water pipe 1, and wherein, interior water pipe 1 is first pipeline, and connecting pipe 5 is the second pipeline.

Inner tube 1 is fixed at the inner bag wall of dish washer, and 6 fixed connection of toper pipe are in inner tube 1, and the cooperation of pegging graft each other of the toper pipe 6 of protrusion structure and the sleeve 8 of protrusion structure, sleeve 8 are fixed in connecting pipe 5, and connecting pipe 5 is fixed at the bowl basket. When the door body of the existing dish washing machine is in a closed state, the front end of the dish basket is contacted with the inner door 3. Therefore, by closing the door of the dishwasher and holding the basket, the sleeve 8 can be fitted with the tapered tube 6, as shown in fig. 2 where the sleeve 8 is fitted with the tapered tube 6.

Wherein the structure has a certain taper, the taper formed by the tapered tube 6 is 5 degrees to 60 degrees, preferably, the taper is 30 degrees. The taper formed by the tapered tube 6 has a guiding effect, which facilitates a structural sliding fit with the sleeve 8. And under the state of closing the door, the door is in sliding fit with the inner side wall structure of the fixed sleeve 8.

In order to realize installation and matching, the sealing ring 7 adopted by the design is a type that the cross section is bent in a shape like a Chinese character '7' and the inner ring and the outer ring are integrally formed, the sealing ring 7 is a section as shown in figure 2, the front surface of the sealing ring 7 belongs to a circular ring structure as shown in figure 3 and consists of the inner ring and the outer ring, an annular flange formed by the inner ring is extruded on the outer side wall of the conical tube 6 in a butting mode, and an annular flange formed by the outer ring is embedded in a groove formed in the side wall. The end of the sleeve 8 is wrapped by a bending corner formed by the preferred sealing ring 7, and then an annular flange formed by the outer ring of the sealing ring 7 is embedded into a groove formed on the outer side wall of the sleeve 8. Further, the groove is a ring of annular grooves around the circumference of the sleeve 8, and at least one ring of annular grooves is arranged. The number of the annular grooves is the same as that of the annular flanges formed on the outer ring of the sealing ring 7, and more annular grooves and annular flanges can be arranged in a matching way, so that the stability and the sealing performance of the sealing ring 7 arranged on the sleeve 8 are enhanced.

Because the sealing ring 7 is fixed on the sleeve 8, the whole connecting assembly can play a role in sealing, and when the dishwasher is in a working state, the water leakage between the conical pipe 6 and the sleeve 8 is prevented, so that the water flows to the spray arm. The sealing material of the gasket 7 is preferably rubber, and has a certain elasticity. This effectively secures the sleeve 8. The annular flange formed by the inner ring of the sealing ring 7 is provided with inclination, and the inclined annular flange is bent and inclined towards the inner side of the sleeve 8, wherein the inclined surface formed by the annular flange formed by the inner ring of the sealing ring 7 and the sleeve 8 form an included angle of 20-60 degrees.

The sealing principle of concrete realization: as shown in fig. 2, after water enters from the water flow direction b, the sealing ring 7 is extruded outwards by the water pressure direction c of the water, the sealing ring 7 is blocked by the taper of the tapered pipe 6, and the flange of the sealing ring 7 is tightly attached to the taper of the sleeve 8, so that the water leakage is effectively prevented, the sealing effect is achieved, the sealing ring 7 has both the sealing effect and the guiding effect, and the sealing matching with the sleeve 8 is facilitated.
