In order to solve the problem that the performance of a spray head of a washing machine is poor in the prior art, the application provides the spray head for the washing machine and the washing machine.
In the following embodiments of the present application, the washing machine is referred to as a drum washing machine. Of course, the spray head for the washing machine in the present application is also applicable to a pulsator-type washing machine.
As shown in fig. 3 to 11, the shower head for a washing machine in the present application includes a coupling pipe section 10 and a shower pipe section 30. The connecting pipe section 10 is used for connecting with a water supply pipeline 20; the spray pipe section 30 is connected with the connecting pipe section 10, the spray pipe section 30 and the connecting pipe section 10 are provided with communicated spray channels 40, the spray channel 40 at one end of the spray pipe section 30 far away from the connecting pipe section 10 is provided with a channel-variable section 41, the channel-variable section 41 is gradually enlarged along the direction far away from the connecting pipe section 10 in the first direction, the wall thickness of each part of the spray pipe section 30 is completely different or partially different, so that the outer surface of the spray pipe section 30 is provided with a scratch-resistant section 31, the scratch-resistant section 31 is composed of an arc-shaped section and/or a plane section, and a spray opening 42 communicated with the spray channels 40 is arranged at the scratch-resistant section 31.
When the spray header for the washing machine in the application is used, the spray header for the washing machine comprises the connecting pipe section 10 and the spray pipe section 30, so that the spray header can be connected with the water supply pipeline 20 of the washing machine through the connecting pipe section 10 and can stretch into the washing cavity of the washing machine through the spray pipe section 30, the spray coverage range of the spray header can be enlarged, all clothes in the inner barrel can be covered, and the washing effect of the washing machine can be guaranteed. Moreover, since the wall thicknesses of the spray pipe sections 30 are completely or partially different, the wall thicknesses of the corresponding positions of the spray pipe sections 30 can be changed according to the shapes or positions of the spray channels 40, so that the outer contours of the spray pipe sections 30 can be smoother or the shapes can be more regular, and the outer bulges or edges of the spray pipe sections 30 are reduced. That is to say, the scraping-preventing surface section 31 composed of the arc-shaped surface section and the plane section can be formed on the outer surface of the shower pipe section 30 by arranging different wall thicknesses at various positions of the shower pipe section 30, so that the scraping of clothes in the washing machine caused by the irregular shape of the shower head can be effectively avoided. Therefore, the spray header for the washing machine effectively solves the problem that the use performance of the spray header of the washing machine in the prior art is poor.
It should be noted that the spray head for the washing machine in the application is mainly used for canceling a rinsing link of the washing machine after washing, directly entering a dehydration program, continuously or intermittently spraying clothes through the spray head for the washing machine in the application while dehydrating, and making water flow penetrate through the clothes and take away detergent residues by utilizing centrifugal force of high-speed rotation to achieve the same rinsing effect as that of conventional rinsing. And, after the shower head used for washing machine is installed to the washing machine, there is included angle between the axis of the variable channel section 41 and the vertical direction, thus can guarantee the shower angle of the shower head used for washing machine is greater, can cover all clothes of inner tube. And because the spray header for the washing machine in the application also has the scraping-preventing surface section 31 without obvious edges and corners, the clothes can be prevented from being scraped in the washing process.
