Abstract
Provided is a dual venturi. The dual venturi includes a housing including a housing body opened in a reference direction so that a gas or air flows, an inner partition wall through which an inner space of the housing body is divided into a first conduit and a second conduit, and a gas providing part provided with a first gas conduit passing through the first conduit to allow the first conduit to communicate with the outside therein and a second gas conduit configured to allow the second conduit to communicate with the outside, an opening/closing unit disposed in the inner space to open and close the first gas conduit and the second conduit, and a driver connected to the opening/closing unit to provide driving force to the opening/closing unit.
Claims12
A dual venturi comprising:
- a housing comprising a housing body opened in a reference direction, an inner partition wall through which an inner space of the housing body is divided into a first conduit and a second conduit, and a gas providing part provided with a first gas conduit passing through the first conduit to allow the first conduit to communicate with the outside of the housing and a second gas conduit configured to allow the second conduit to communicate with the outside of the housing;
- an opening/closing unit disposed in the inner space of the housing body to open and close the second gas conduit and the second conduit;
- and
- a driver connected to the opening/closing unit to provide driving force to the opening/closing unit,
- wherein the second gas conduit comprises:
- a (second-1)th gas conduit configured to communicate with the outside of the housing and opened and closed by the opening/closing unit;
- and
- a (second-2)th gas conduit configured to allow the (second-1)th gas conduit to communicate with the second conduit,
- wherein the opening/closing unit comprises a damper configured to control a flow of gas flowing through the second gas conduit,
- wherein the damper moves in a longitudinal direction of the (second-1)th gas conduit inside the (second-1)th gas conduit by the driver to control the flow of gas,
- wherein one end of the second gas conduit comprises an opening that is exposed to the outside of the housing,
- the damper moves along the longitudinal direction of the (second-1)th toward the opening by the driver to open the (second-1)th gas conduit, and
- the damper moves in a direction opposite to the direction facing the opening to close the (second-1)th gas conduit.

A dual venturi comprising:
- a housing comprising a housing body opened in a reference direction, an inner partition wall through which an inner space of the housing body is divided into a first conduit and a second conduit, and a gas providing part provided with a first gas conduit passing through the first conduit to allow the first conduit to communicate with the outside of the housing and a second gas conduit configured to allow the second conduit to communicate with the outside of the housing;
- an opening/closing unit disposed in the inner space of the housing body to open and close the second gas conduit and the second conduit;
- and
- a driver connected to the opening/closing unit to provide driving force to the opening/closing unit,
- wherein the second gas conduit comprises:
- a (second-1)th gas conduit configured to communicate with the outside of the housing and opened and closed by the opening/closing unit;
- and
- a (second-2)th gas conduit configured to allow the (second-1)th gas conduit to communicate with the second conduit,
- wherein the opening/closing unit comprises a damper configured to control a flow of gas flowing through the second gas conduit,
- wherein the damper moves in a longitudinal direction of the (second-1)th gas conduit inside the (second-1)th gas conduit by the driver to control the flow of gas,
- wherein one end of the second gas conduit comprises an opening that is exposed to the outside of the housing,
- the damper moves along the longitudinal direction of the (second-1)th toward the opening by the driver to open the (second-1)th gas conduit, and
- the damper moves in a direction opposite to the direction facing the opening to close the (second-1)th gas conduit,
- wherein the opening/closing unit further comprises a cam assembly configured to connect the damper to the driver,
- wherein the cam assembly comprises:
- a cam body disposed inside the second gas conduit and the second conduit;
- and
- a cam guide passing through the cam body to connect the damper to the driver,
- wherein the opening/closing unit further comprises a blade assembly coupled to the cam body,
- wherein the blade assembly rotates inside the second conduit to control a flow of air flowing in the second conduit,
- wherein the blade assembly comprises:
- a blade body connected to the driver and disposed inside the second conduit;
- and
- a wing part disposed on an outer surface of the blade body to open and close the second conduit,
- the cam body comprises:
- a first cam body disposed inside the second gas conduit;
- and
- a second cam body connected to the first cam body and being in contact with the blade assembly of the opening/closing unit,
- the second cam body moves in the direction facing the opening or an opposite direction by allowing the blade body to rotate by the driver so that convex portions of each of the second cam body and the blade body are in contact with each other to correspond to each other or are engaged with each other, and
- the cam guide connected to the second cam body passes through the first cam body to allow the damper to move in the direction facing the opening or the opposite direction.
