Abstract

The invention provides a flaring-shaped spray header and a washing machine, the flaring-shaped spray header comprises a connecting pipe section, a middle pipe section and a contraction pipe section, and the connecting pipe section is used for being connected with a water supply pipeline; the two ends of the middle pipe section are connected with the connecting pipe section and the shrinkage pipe section correspondingly, the shrinkage pipe section expands in the first direction in the direction away from the middle pipe section and shrinks in the second direction, and the first direction is perpendicular to the second direction; wherein the two end points of the contraction pipe section in the first direction are a point B and a point C respectively, and the distance AE from any point A on the middle pipe section to any point on the spraying surface of the contraction pipe section is larger than the vertical distance AD from the point A on the middle pipe section to the connecting line of the point B and the point C. The problems that in the prior art, a spraying system of a washing machine is limited in coverage range, and complete coverage of the front end and the rear end of a whole inner barrel is difficult to achieve are solved.

Description

technical field

[0001] The invention relates to the technical field of household appliances, in particular to a flared spray head and a washing machine. Background technique

[0002] At present, most washing machines will perform rinsing after completing the main washing process, so as to remove residual detergent, and then perform dehydration and drying. However, if there is too much rinsing, time will be wasted, which will undoubtedly increase the total washing time. In addition, the processes of rinsing, rinsing, washing, and draining all take a certain amount of time, and multiple dehydration increases the time for clothes to find a balance, which not only prolongs the total washing time, but also increases energy consumption such as power consumption. At the same time, in the rinsing stage, the drum also needs to be rotated to drive the clothes to be beaten or rubbed, which will increase the wear or deformation of the clothes to a certain extent. On the other hand, at...

Examples

Embodiment 1

[0041] Such as Figure 3 to Figure 6As shown, the flared shower head includes a connecting pipe section 10, an intermediate pipe section 20 and a shrinking pipe section 30. The connecting pipe section 10 is used to connect with the water supply pipeline 1; 30 connection, the shrinkage pipe section 30 expands in the first direction and shrinks in the second direction along the direction away from the middle pipe section 20, and the first direction and the second direction are perpendicular to each other; wherein, the two end points of the shrinkage pipe section 30 in the first direction Points B and C respectively, the distance AE from any point A on the middle pipe section 20 to any point on the spray surface 31 of the shrink pipe section 30 is greater than the vertical distance from point A to point B and point C on the middle pipe section 20 AD.

[0042] Using the flaring spray head in this application can effectively avoid the blind area of ​​the glass bowl through the con...

Embodiment 2

[0057] It should be noted that the difference between this embodiment and Embodiment 1 is that, as Figure 7 As shown, the spray surface 31 includes a BE1 plane segment, an E1E2 straight line segment and a CE2 straight line segment.

Embodiment 3

[0059] It should be noted that the difference between this embodiment and Embodiment 1 is that, as Figure 8 As shown, the spray surface 31 includes a BE1 arc segment, an E1E2 straight line segment, and a CE2 arc segment.
