For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood on a case-by-case basis.

As shown in Figures 1 to 6, the present invention provides a washing machine connecting hose 1. The connecting hose 1 can be used to connect the outer drum 2 of the washing machine and the water box 3 of the washing machine, and water can be fed into the outer drum 2 through the water box 3 and the connecting hose 1; or the connecting hose 1 One end is connected to the outer cylinder 2, and the outer cylinder 2 is connected to the inner cylinder. The other end of the connecting hose 1 is connected to the atmosphere outside the washing machine to maintain the balance of the internal and external air pressure of the washing machine.

The connecting hose 1 includes a first connecting pipe section 11, a corrugated pipe section 12 and a second connecting pipe section 13 connected in sequence.

The outer peripheral wall of the first connecting pipe section 11 is provided with an annular boss 14 that protrudes and extends outward. The outer peripheral wall of the annular boss 14 is provided with a clamping groove 141 that is recessed inward for use. It is detachably connected to the outer drum 2 of the washing machine.

An annular boss 14 is provided on the outer peripheral wall of one end of the connecting hose 1 of the present invention. A clamping groove 141 is provided on the outer peripheral wall of the annular boss 14 and is recessed inward. The connecting hose 1 is installed with the outer cylinder 2 When connecting, it can be extended into the installation opening 21 and directly clamped on the inner and outer sides of the installation opening 21 of the outer cylinder 2 without the need for Adding other matching installation structures at the installation opening 21 of the outer cylinder 2 can also prevent the washing foam in the outer cylinder 2 from overflowing to the outside. The structure is simple, easy to install, and low in cost.

Preferably, the annular boss 14 is an elastic member.

During installation, the first connecting pipe section 11 of the connecting hose 1 needs to be inserted into the installation port 21 of the outer cylinder 2. Since the annular boss 14 has a certain elasticity, the annular boss 14 can be slightly pinched inward during insertion. , extend part of the annular boss 14 and the end of the first connecting pipe section 11 into the interior of the outer cylinder 2, and then release the annular boss 14, so that the two side walls of the clamping groove 141 are clamped in the installation opening 21 on the inner and outer side walls of the outer cylinder 2 on the outer periphery.
