Surface treating appliance |
摘要 |
A surface treating appliance, such as a vacuum cleaner, includes a device generating a flow of fluid in the form of a motor and fan, housed in a main body. A hose and wand assembly, a surface treating head and a rotary change over valve are also provided. The valve is selectively rotatable so as to allow fluid flow from either the surface-treating head or the hose. A support assembly is moveable between a supporting position, in which it supports the main body, and a retracted position. The change over valve and support assembly are arranged so that motion of the support assembly between the supporting and retracted positions induces rotary motion of the change over valve. |

1. A surface treating appliance comprising a device for generating a flow of fluid, a main body, a hose, a surface treating head and a change over valve, the valve being selectively moveable so as to allow fluid flow from either the surface-treating head or the hose, and a support assembly moveable between a supporting position, in which the support assembly supports the main body, and a retracted position, the support assembly comprising a stand arranged to engage a floor surface in the supporting position and to move pivotably with respect to the main body as the support assembly moves between the supporting and retracted positions, whereby pivoting motion of the stand is converted into motion of the change over valve. |
