摘要： PURPOSE:To blow blowing air not providing any uncomfortable feeling to a human body while reducing noise by a method wherein the blowing area of an indoor blowing port is set to be larger than the opening area of a blowing duct and a striking wall for dispersing a blown flow from the blowing duct is provided. CONSTITUTION:As an indoor air circulation fan not shown is driven, indoor air is sucked from each of indoor air suction ports 22 set at an upper part and a lower part of an indoor panel 11. The indoor air passes through a suction passage 25 and a suction side duct 10a, the air is guided to an indoor heat exchanger not shown placed outside a room and is heat exchanged. The heat exchanged indoor air passes through a blowing duct 10b and is guided to an indoor panel 11. At this time, the indoor air strikes against a belt-like plate 27 acting as a striking wall disposed in a blowing passage 26. Due to this arrangement, the indoor air is dispersed upwardly, downwardly, rightwardly and leftwardly and then blown from an indoor air blowing port 23 into a room. Since the area of the blowing port of the indoor air blowing port 23 is set to be larger than the opening area of the blowing side duct 10b, the blown air is blown at a lower speed.

摘要： PURPOSE:To assure a desired cooling or heating performance with a small duct passing-through part by a method wherein the upstream side and the downstream side of an air passage passing through an indoor side heat exchanger within a casing is provided with two indoor fans for circulating indoor air to the indoor heat exchanger through a duct. CONSTITUTION:As a fan motor 9 having two shafts in a casing 1 installed at an outer surface of a wall part B of an indoor part A is driven, two indoor air circulation fans 7 and 8 are concurrently operated. Then, air in the indoor area A is sucked from a suction grill 12a of an indoor panel 11. The indoor air becomes an injection flow, passes through a duct 10a on the suction side, flows from a suction port 2 of the casing 1 into an air passage 6, the air is guided to an indoor heat exchanger 5 placed on the outdoor side C and is heat exchanged there. After this operation, the heat exchanged indoor air becomes a rapid flow, passes from a blowing port 3 of the casing 1 through a blowing duct 10b, flows to a blowing grill 12b of an indoor panel 11 and this air is guided into an indoor area A. As a result, either cooling or heating of the indoor area A is carried out.

摘要： PURPOSE:To reduce the amount of CO to be generated at the time of a low combustion rate by a method wherein a second air injecting means for injecting secondary combustion air from the central part of a combustion chamber into the interior of the combustion chamber is provided in the combustion chamber. CONSTITUTION:Air for combustion, which flows through the inside of an outer cylinder 1, is partly sent to a secondary air introducing pipe 18 and to a secondary air feed passageway 8 as secondary combustion air. The secondary combustion air introduced into the secondary air introducing pipe 18 passes through the inside of a hollow body 16 and is injected toward the central part of a combustion chamber 15 through secondary air injection ports 17. On the other hand, the secondary combustion air introduced into the secondary air feed passageway 8 is injected to the peripheral side of the combustion chamber 15 through secondary air injection ports 14. In the case of a low combustion rate, the secondary combustion air is injected from the secondary air injection ports 14 on the combustion chamber 15 side to the peripheral portions of flames formed at a group of burner ports 13b of a burner port plate 13, and the secondary combustion air is also injected from the secondary air injection ports 17 on the hollow body 16 side to the central part of the flames where the shortage of air occurs. Accordingly, the amount of CO to be generated at the time of a low combustion rate can be reduced.

摘要： PURPOSE:To attempt to extend the range of combustion with a stable state of combustion maintained by providing means to make the combustion quantity variable and a controller which controls the rotational speed of a motor used for atomization by rotation and the rotational speed of the motor of a blower fan according to the combustion quantity. CONSTITUTION:A control section 21 brings to a high rotational speed the rotational speed of a motor 9 used for atomization by rotation at the initial stage of ignition, and at the same time it controls a flow rate adjust valve 16 so as to make the flow rate of the fuel minimum. When a certain time has passed after ignition it is set up that the rotational speed of the motor 9 and the degree of opening of the flow rate adjust valve 16 are returned to the rotational speed and the degree of opening in accordance of the state of combustion. Therefore, at the initial stage of ignition the atomization of the fuel is promoted and fuel particles become smaller to make the contact of the air with the fuel good and the fuel easy to burn. On the other hand a rotary cup 11 is gradually heated from the surrounding by the flames that are formed in the neighborhood around a combustion chamber 2 so that the flow rate adjust valve 16 opens up to the degree of opening of the combustion quantity that is set. Then, the flow rate of the fuel increases and the combustion quantity increases, and at the same time a motor for supplying combustion air is controlled to a rotational speed at which the combustion air required for combustion quaintly is obtained and the air to fuel ratio is brought to a value which is suitable for combustion.

摘要： PURPOSE:To improve the degree of the mixing of fuel and air and facilitate the supply of secondary air by providing a flame stabilizer with an opening only in the direction of the whirl of the air and at the same time piercing secondary air discharge holes in a large number and in many stages and providing a fuel evaporation plate at a position close to the secondary air discharge holes in the first stage inside the stabilizer. CONSTITUTION:A flame stabilizer 7 is formed as a box only one side face of which is cut off and three other side faces of which are closed, and all the air that goes through this flame stabilizer 7 flows only in one direction of this opening. The air passing through this opening gains sufficient swirling force to improve the state of mixture of fuel and air. Secondary air discharge openings 12 in a large number are pierced in many stages through the circumferential wall of a cylinder 9 in a combustion chamber. A fuel evaporation plate 14 that is made of ceramics and installed near the air discharge ports 12 which are positioned in the first stage performs moisture absorption for the fuel at the beginning of its ignition and when the temperature of the evaporation plate 14 is raised, it performs its role as an evaporator, and at the same time it catches the atomized fuel which has a large diameter or atomized fuel droplets which are not uniform to evaporate the fuel smoothly. Further, the secondary air discharge ports 12 replenish the air which is not sufficient in the mixture of the fuel that was evaporated by the fuel evaporation plate 14 and the air so that the combustion is maintained in multiple stages.
