Claims

[Claims for Utility Model Registration] 1. A small-diameter inner cylinder is disposed inside the outer cylinder through an air passage that is ventilated by a blower, and a primary air inlet that communicates with the air passage is provided at the rear of the inner cylinder. At the same time, a variable flow rate atomizer for liquid fuel was installed near the rear of the inner cylinder with the spray port facing forward.
On the front side of the spray nozzle, there is a disc-shaped swirler body.
A swivel having a hole in the center, a plurality of circumferential openings around the hole, and a bent piece facing the circumferential opening on one side in the radial direction of the swivel body in the circumferential opening. A swirler made of upright blades is provided, and the inner cylinder on the front side of the swirler has multiple rows of secondary air inlet ports each having a plurality of openings in one row in the inner circumferential direction. In the provided burner, the bent piece of the swirl vane is placed parallel to the circumferential opening in the circumferential direction of the swirler body, and the space between the bent piece and the circumferential opening extends from the hole toward the outer periphery of the swirler body. A variable combustion amount oil burner characterized by being formed to be wider. 2. A water heater comprising the variable combustion amount oil burner according to claim 1. 3. A bathtub with hot water supply equipped with the variable combustion amount oil burner according to claim 1.
