ある。2. Description of the Related Art Conventionally, this type of oil hot water heater has a configuration as shown in FIG. As shown in the drawing, the periphery of the burner 1 is covered by a substantially U-shaped burner case 2 and a vaporizing cylinder 3 having a heater on the substantially U-shaped opposite surface. The vaporizing cylinder lid 4 is attached to the vaporizing cylinder 3 to seal a vaporized gas. A nozzle 5 having an opening and ejecting fuel to the vaporizing cylinder 3 is provided above the vaporizing cylinder lid 4. The nozzle 5 is fixed to a case shell 6 that covers the burner case 2, and ejects oil sent from an electromagnetic pump 7 for oil supply to an evaporating cylinder 3 through an oil feed pipe 8. The blower 9 has a spiral casing for supplying combustion air, and is attached to the case shell 6. The mixing chamber 10 supplies the vaporized gas in the vaporizing cylinder 3 to the burner 1 and is formed below the burner 1. In the figure, reference numeral 11 denotes a heat exchanger provided above the case shell 6, and reference numeral 12 denotes an exterior of the main body of the device.

市場でのサービス性が悪いという問題があった。However, in the above-mentioned conventional construction, the blower 9 having the spiral casing has a large wind speed on the outer periphery of the casing and a small wind speed on the inner periphery, so that the blower 9 is directly connected to the casing 6. , The speed distribution at the outlet of the blower 9 is such that the outer circumference of the blower 9 is strong and the inner circumference is weak.
As a result, the combustion air distribution is largely deviated before and after the burner 1, and there is a shortage of combustion air in front of the burner 1, soot is generated. Combustion performance was poor.
Also, since the blower 9 is fixed to the side of the case shell 6, only the blower 9 cannot be removed from the exterior,
There was a problem that serviceability in the market was poor.

In this embodiment, the same components as those shown in the above-described conventional example are denoted by the same reference numerals, and the description thereof will be omitted. The characteristic configuration of the present embodiment is that a box-shaped case is provided on the outer case of the case described in the conventional example and communicates with the outlet of the blower. That is, a box-shaped case 13 having an open top is attached to the side surface of the case shell 6, and an L-shaped attachment member 15 is provided at a part of the discharge tip of the blower 14. The discharge end of the blower 14 is tilted rearward with respect to the opening of the box-shaped case 13 via the mounting member 15 and fixed to form a ventilation passage.

することができる。In the above configuration, the combustion air sent from the blower 14 is supplied to the case shell 6 through the box-shaped case 13, and therefore, even if there is a velocity distribution at the outlet of the blower 14, the combustion air is generated by the box-shaped case 13. The burner 1 is supplied to the burner 1 in a uniform and near static pressure state, and stable and constant combustion air is obtained in the entire area of the burner 1, and the combustion state is also stabilized. Also, the tip of the outlet of the blower 14 is
And the entire blower 14 is tilted rearward with respect to the box-shaped case 13 so that the L-bent mounting member 15 and the box-shaped case 13 can be fixed from the front, and the blower 14 is fixed. Even before the blower 14 is temporarily placed in the box-shaped case 13, the blower 14 does not fall down, so it is possible to work without supporting with the hand, and maintenance of the blower 14 in the market is performed.
Sex is better. In addition, the spiral casing of the blower 14
Tilt the communicating air passage to the box case 13
So that the spiral casing is approximately centered.
It can be installed in the
You. Further, by inserting the outlet end of the blower 14 into the box-shaped case 13, the passage area of the blower passage is changed, and the noise level can be reduced because the blower also serves as a hollow silencer.
