Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a configuration of an air outlet of an air conditioner used for heating or cooling into a room.

[0002]

2. Description of the Related Art Various types of air blowing configurations of this type have been proposed in the past, some of which are used for hot air heating by burning fuel gas obtained by vaporizing gas or kerosene. Hereinafter, a description will be given of a hot air heater used for hot air heating by burning this liquid fuel gas as an example. Such a hot air heater is shown in FIG.
It is configured as shown in FIGS. 7, 8, and 9.

That is, first, fuel is supplied from a cartridge tank 2 to a tank (not shown), and the fuel in the tank is supplied to a burner section 4 by a pump (not shown) and is burned there. The generated combustion exhaust gas is guided upward by a heat exchanger 5 disposed so as to cover the periphery of the burner section 4.
In a duct 6 covering the heat exchanger 5, the air is mixed with a room air flow from a blower 7 including a propeller fan and a blower motor,
The air is discharged from the outlet 8 as warm air through the louver 9 into the room and used for heating. When the fuel supply amount is adjusted by changing the driving frequency and applied voltage of the pump 3, the primary air amount increases and decreases accordingly, and the combustion amount is changed while the fuel-to-air ratio is kept constant. Is available.

[0004]

However, in the air blowing configuration of the device having such a configuration, parts such as the tank 1, the cartridge tank 2 and the control board are inevitably placed on the side of the main body case, that is, on the side of the duct 6 in terms of parts arrangement. In such a case, the hot air outlet 8 cannot be arranged almost the entire front width of the main body case.
The front side of the side of the main body case where the parts are placed, for example, the side of the duct 6, is substantially closed. Therefore, there is a disadvantage that it is difficult to balance the left and right of the hot air blowout, it is not possible to blow out the entire front surface of the main body case wide, and it is not possible to improve the feeling of heating.

In order to solve such a problem, the characteristic of air flowing along the wall surface due to the viscosity of the air is conventionally used to apply hot air to the side of the outlet of the duct 6 as shown in FIG. A method has been proposed in which a guide 10 is provided in the side direction to guide the flow, or a small room 11 is provided on the side of the duct 6 as shown in FIG.

However, even in such a configuration, the hot air has a low flow velocity, is low in density and low in viscosity due to the hot air, and uses a blower 7 including a propeller fan and a blower motor, so that the hot air is not heated. The flow is not laminar, so the amount of air flowing along the wall is small due to the viscosity of the air flow,
In the above-described method in which the guide 10 is provided in the lateral direction so as to guide the flow of warm air, and in the method in which the small chamber 11 is provided on the side of the duct 6 described later, the effect is not so high, and There was a drawback that it was not possible to blow out wide enough to the entire front area, and it was not possible to improve the heating sensation sufficiently.

[0007] The present invention has been made in view of the above problems,

A box-shaped duct that forms an air passage that mixes the heat exchanged with the heat source with the air flow from the blower and discharges the air from the outlet, and the air flow from the blower near the discharge port of the duct. And a propagation means to spread the
The propagating means is configured to be wider in the lateral direction than the outlet of the duct so that the wind of the airflow from the blower is blown out from the outlet wider than the outlet of the duct.

According to the above invention, the propagation means is provided near the discharge port of the duct to receive the wind and spread in the horizontal direction, so that the air flow discharged from the duct is subjected to heat exchange to generate hot air or cold air. Part is received by the propagating means, the hot air or cold air is conveyed in the lateral direction of the propagating means, and the hot air or cold air is blown out from the propagating means that is wider than the width of the duct. Can be blown out from the air outlet more widely than the discharge port, and with a simple configuration, the hot air or the cold air can be blown out in a wide range, so that the feeling of warming and cooling can be improved.

[0013] As a propagation means, a part of an air flow of hot air or cold air generated by heat exchange flowing forward in the duct in the propagation chamber is dammed and sent laterally, and the hot air or cold air is transmitted to the propagation chamber. Is sent to the propagation side chamber provided in communication with the air, and is blown out as warm air or cold air from the propagation side chamber, and the hot air or cold air is discharged from the outlet of the duct and from the propagation side chamber through the propagation chamber. As the sum of the discharged air, the air is blown out from the air outlet widely in the lateral direction of the propagation side chamber, and the effect of claim 1, that is, the hot air or the cold air can be widely blown out with a simple configuration. As a result, the feeling of heating or the feeling of cooling can be improved.
