[Industrial applications]

 In this invention, while supplying the cleaning liquid to the surface of the carpet or tatami mat, this is brushed with a cleaning brush, and the dirty water (foam) after cleaning is sucked by the nozzle attached to the rear part of the machine and collected in the dirty water tank. The present invention relates to a carpet and tatami washer used in the technical field, and specifically relates to an improvement of a wastewater suction nozzle suitable for use in the carpet and tatami washer. .

[0002]

[Prior art]

 A conventional washing machine used for washing carpets and tatami has a recovery port (nozzle) opened at the rear bottom surface of the machine body as described in, for example, Japanese Patent Application Laid-Open No. 58-61720, and a suction action of a blower at this recovery port. The sewage and bubbles after brushing are sucked up and collected from this collection port by exerting the action.

However, in the washing machine having the above-mentioned structure, even if a strong suction action of the blower is exerted on the recovery port, there is a slight gap between the recovery port and the surface to be cleaned, so that the carpet Since the suction action cannot be sufficiently exerted to the depth of the weave or the tatami mat, there is a problem that the dirty water and bubbles after cleaning remain in these carpets or tatami mats.

Therefore, the applicant has formed the tip with a relatively hard material such as casting or plastic, as seen in the above-mentioned Japanese Patent Application No. 4-137763 and Japanese Patent Application No. 4-36168. By directly pressing the tip of the nozzle against a soft carpet surface or tatami mat surface, a nozzle for a washing machine is devised so that the carpet or tatami mat surface and dirty water and bubbles remaining inside can be surely sucked and collected. developed.

[0005]

[Problems to be solved by the device]

 However, in the case of ordinary carpets, the surface is not always flat like the floor surface made of plastic tiles, etc., but it is often a complicated uneven surface depending on the combination of the underlying tools. On the other hand, since the nozzle is made of a hard material lacking elasticity, there is a problem that the nozzle cannot follow the complicated irregularities on the carpet surface and suction leakage occurs.

[0006] Furthermore, since the carpet has a fur coat, if the fur coats are all aligned in the same direction after washing, the carpet surface looks clean. However, in the above conventional washing machine, the nozzle is pressed directly onto the carpet face for washing work. Due to this, for example, when the washing machine is turned at the edge or corner of the floor, the hard nozzle may turn the hair on the carpet face upside down, and the carpet face after washing becomes ugly. There was a problem.

Furthermore, when the tatami surface is cleaned using the above-mentioned washing machine, the tatami surface has many fine irregularities, and in addition, the edges of the tatami surface are particularly convex as compared with other surfaces. Therefore, there are problems that the above conventional hard nozzle cannot follow these uneven surfaces, resulting in non-uniform suction, and that the tatami surface or the edge is damaged by pressing a hard nozzle.

[0008] Therefore, a technical problem of the present invention is to provide a nozzle for a washing machine that can reliably and appropriately exert a suction action on a carpet surface and a tatami mat surface.

[0009]

[Means for Solving the Problems]

 Means taken in the present invention to solve the above technical problems are as follows.

While supplying the cleaning liquid to the surface of the carpet and tatami with the pressure of the pump, the cleaning liquid is brushed by the cleaning brush, and the dirty water and bubbles generated by this brushing are sucked into the dirty water tank through the nozzle attached to the rear part of the machine body. In a washing machine for carpets and tatami mats configured to
