Separately opening dust containers
First Claim
1. A home cleaning appliance comprising:
- a housing comprising a nozzle, including a main suction opening and a brush;
an air stream suction source, mounted to said housing and including a suction airstream inlet and a suction airstream outlet, said suction source selectively establishing and maintaining a suction airstream from said nozzle main suction opening to said airstream outlet;
a cyclone main body, mounted to said housing and in communication with said nozzle main suction opening, said cyclone main body including;
an upstream, first, cyclonic separator for separating dust from dust-laden air, andat least one downstream, second, cyclonic separator for separating remaining dust particles from the air; and
a dirt cup connected to said cyclone main body, said dirt cup including;
a first particle collector communicating with said first separator for collecting dust particles separated by said first separator, anda second particle collector communicating with said at least one second separator for collecting dust particles separated by said at least one second separator, wherein said first particle collector and said second particle collector are configured to empty independently of each other, and a first closure member operably secured to said cyclone main body for emptying of said first particle collector, and a second closure member operably secured to said cyclone main body for emptying of said second particle collector.

Abstract
The present invention relates to a home cleaning appliance including a housing including a nozzle having a main suction opening and a brush. An air stream suction source, mounted to the housing, includes a suction airstream inlet and a suction airstream outlet. The suction source selectively establishes and maintains a suction airstream from the nozzle main suction opening to the airstream outlet. A cyclone main body is mounted to the housing and is in communication with the nozzle main suction opening. The cyclone main body includes an upstream, first, cyclonic separator for separating dust from dust-laden air, and at least one downstream, second, cyclonic separator for separating remaining dust particles from the air. A dirt cup is connected to the cyclone main body. The dirt cup includes a first particle collector communicating with the first separator for collecting dust particles separated by the first separator, and a second particle collector communicating with the at least one second separator for collecting dust particles separated by the at least one second separator. The first particle collector and the second particle collector are configured to empty independently of each other.
