Washing machine with spray-rinsing function
ActiveCN108018667AImprove washing effectAvoid entanglementOther washing machinesWashing machine with receptaclesImpellerLaundry washing machine
The invention relates to a washing machine with a spray-rinsing function. A gap between an inner drum and an outer drum is communicated with a water channel in an impeller through a connection water channel with a water pump, rinsing water between the inner drum and the outer drum flows through the connection water channel and the water channel in the impeller and then is sprayed into the inner drum through spraying holes formed in the surface of the impeller, and water columns ejected upwards are formed in the inner drum for rinsing clothes. Through the arrangement above, the water columns flushing upwards can be constantly formed in the inner drum, correspondingly the clothes are scoured, and the phenomenon that the clothes are wound due to reciprocating inverse rotation can be alleviated, so that damage caused by winding to the clothes is avoided. Meanwhile, since the clothes are constantly turned over during clothes washing, the contact areas between the clothes and the rinsing water are increased, friction is generated among the clothes, and the rinsing effect is effectively improved. Furthermore, the washing machine is simple in structure, remarkable in effect and suitable for popularization and application.

Column-beam connection structure
InactiveCN102209817BWeight increaseAvoid embrittlementArc welding apparatusBuilding constructionsEngineeringHot working
Bending moment applied to a beam causes out-of-plane deformation to a panel when the panel zone is hollow, and thereby a load bearing by a web cannot be expected in an elastic region. Since the section modulus of a beam end is limited to the section modulus of only the flange not including the web, the beam end has a low strength. Therefore, a beam larger in size which bears bending moment on the entire section of the beam must be used and an extra beam depth is required, thus causing an increase in the weight of a steel beam. As the result of various studies, it has been found that various problems could be resolved by increasing the plate thickness of a diaphragm, applying a backing plate to the top surface or the bottom surface of a beam flange, increasing the strength of the material of the beam flange, increasing the thickness of the diaphragm or the backing plate, notching a web, or hot working the bottom surface of the beam to impart prestress thereto.
