Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved configuration of a rotary gasification hot air heater.

In general, a hot air heater using a rotary gasification burner, as shown in the conventional example shown in Fig. 1, has a blower C disposed at the bottom of a board RO which divides the inside of the outer casing into upper and lower halves, and a blower C disposed above the board RO. A combustion device consisting of a rotary gasification burner, a combustion chamber E, a heat exchanger H, etc. is installed, and the accelerated air flow from the blower C is brought into contact with the combustion chamber E and the heat exchanger to generate warm air into the casing. It was being released outside the body.

However, in this conventional warm air heater, the rotary gasification burner is connected to the combustion chamber in the longitudinal direction, and the outer diameter of the rotary gasification burner is determined by the outer diameter of the internal motor and air supply fan. Because of this, it was extremely difficult to make the outer casing thinner, and the width of the outer casing also increased.

The present invention has been improved in view of the above-mentioned points, and includes forming a combustion chamber into a flat hollow shape, and connecting a rotary gasification burner and its driving part orthogonally to the back of the combustion chamber, and By protruding outside the outer casing under the back guard to maintain the distance between the outer casing and the wall of the house (100 mm or more) as determined by JIS standards, the rotary gas generator is thinner and more compact than ever before. This type of hot air heater is provided.

Hereinafter, one embodiment of the present invention will be described based on the drawings from FIG. 2 onwards. Reference numeral 1 denotes an outer casing which has a warm air outlet 2 at the upper part of the front surface and whose interior is divided into upper and lower halves by a board 3, and below the board 3 are a motor 4a and a blower fan 4b for generating an accelerated air flow. A hot air blower 4 comprising a fan case 4c and the like, and an oil leveler 6 connected to a separate fuel tank via a fuel supply pipe 5 are provided.

Reference numeral 7 denotes a rectangular, flat, hollow combustion chamber installed in an upright state in the air supply passage 8 of the blower 4 formed on the upper part of the substrate 3 and along the left-right direction of the outer casing 1; An exhaust gas collection case 10 is provided on the side of the combustion chamber 7 and is connected to the exhaust gas collection case 10 through heat exchange pipes 9, 9, . . . 11 to the outside.

Reference numeral 12 denotes a rotary gasification burner connected to the back wall 7A of the combustion chamber 7 in a manner substantially perpendicular to the back wall 7A. Motor case 16 in which type air supply fans 15, 15 can be installed
, a vaporization case 18 that communicates with the motor case 16 via a rectification case 17, a secondary air supply case 19 that covers the outer circumference of the vaporization case 18, and the vaporization case 18.
The fuel atomizer 20 is composed of a rotary cone 20a, a scattering plate 20b, and a stirring plate 20c, which are fixed to the tip of a motor shaft 14 that is thrust into the fuel atomizer 20, and the vaporizer casing 18 has a heater 2 on its peripheral wall.
1 is embedded, and a vaporizer casing 1 is installed in the opening at the tip.
A burner head 23 that forms flame ports 22, 22, . A large number of slits 24, 24 are formed in the flap-shaped flange 23a so as to open in a fan shape at an angle of about 140° to 220° on the side of the periphery and on the upper part.
. . . and projections 25, 25 . . . are formed alternately, and this burner head 23 is connected to the combustion chamber 7.
The driving portions of the motor case 16 and the like, which house the drive motor 13 for rotating the atomizer 20 and the air supply fan 15, are made to pass through the back wall 1A of the outer casing 1 so as to face inside the back wall 1A. It projects into the space below the back guard 26 mounted on the top.

27 is a liquid fuel supply pipe whose tip opening faces the rotary cone 20a of the atomizer 20;
This supply pipe 27 communicates with the oil leveler 6 via a solenoid valve 28, a piping box 29, and an electromagnetic pump 30, and the liquid fuel pumped up by the electromagnetic pump 30 is dripped from this supply pipe 27 to the rotary cone 20a. Supplied. Further, 31 is a spark plug whose tip is close to the flame port 22.

32 is located on the outside of the front wall of the combustion chamber 7 facing the burner head 23 of the rotary gasification burner 12,
A humidifying container with an upper opening formed integrally with the front wall of the combustion chamber 7, and the humidifying container 32 has its upper opening in the vicinity of the hot air outlet 2 so that water vapor is contained in the hot air. It has been done.

Next, the operation of the present invention will be described. After the vaporizer casing 18 is heated by energizing the heater 21 and reaches a temperature at which kerosene can be vaporized, the drive motor 13 is started to start the atomizer 20. rotate it,
Fuel is supplied to the atomizer 20 from the fuel supply pipe 27. Then, the fuel atomized by the atomizer 20 is vaporized in the vaporization case 18, and this vaporized gas is mixed with the accelerated airflow of the air supply fan 15 to become a gas mixture,
The flame is ejected into the combustion chamber 7 from the flame ports 22, 22, ignited and burned, and at this time, the combustion flame flows into the burner head 23.
The flame spreads in a fan-like manner laterally around the periphery. Furthermore, the combustion exhaust gas in the combustion chamber 7 passes through heat exchange pipes 9, 9, .

When the blower 4 is started as soon as the temperature of the combustion chamber 7 becomes high, the accelerated air flow from the blower 4 is transferred to the combustion chamber 7 and the heat exchange pipes 9 and 9 in the blow passage 8.
The hot air is exchanged with the hot air and is discharged into the room from the hot air outlet 2 as hot air. Further, the water in the humidifying container 32 heated by the hot combustion air in the combustion chamber 7 rises as steam from the upper opening, and then mixes with warm air and is discharged into the room from the hot air outlet 2. Acts as a humidifier.

As described above, according to the present invention, there is provided a back wall having a back guard on the upper part of the back wall, an air supply passage for a hot air blower formed in the outer casing, and an air supply passage extending along the left and right direction of the outer casing. The rotary gasification burner includes a flat hollow combustion chamber provided in an upright state in a passage, and a rotary gasification burner provided on a back wall of the combustion chamber and connected to the back wall substantially orthogonally. , wherein a flame port portion faces into the combustion chamber, and a drive unit having an air supply fan and a drive motor penetrates the back wall of the outer casing and projects into the space below the back guard. Therefore, the space below the back guard can be effectively used, the front and rear dimensions and width of the outer casing can be set small, and a compact rotary gasification hot air heater can be provided.

In addition, since the drive section of the rotary gasification burner, which includes an air supply fan and a drive motor, penetrates the back wall of the outer casing and protrudes to the outside, the cooling effect of the drive motor can be greatly improved, reducing thermal effects. This can reduce motor failures caused by
