FIG. 5 is a side sectional view showing a detailed configuration of the outlet of the oil fan heater 51. The petroleum fan heater 51 includes a fuel tank 52, a fuel pump electromagnetic pump 54, an oil feed pipe 55, a carburetor 56, a combustion chamber 57, and a burner 58 inside the main body. The kerosene 53 stored in the fuel tank 52 is pressure-fed to the vaporizer 55 heated by the vaporizer heater via the oil feed pipe 55 by the fuel pressure feeding electromagnetic pump 54, and the burner disposed in the combustion chamber 57. Burned at 58.

The high-temperature combustion gas generated by the burning of the kerosene 53 in the burner 58 is supplied to a blower fan 60 directly connected to a blower motor 59 provided on the back side of the combustion chamber 57.
Is mixed with the indoor air sucked from the suction port by
The hot air is discharged into the room from an outlet 61 formed on the front side. After the combustion in the burner 58 starts, the blower motor 59 is energized when the flame detection sensor detects a combustion flame having a flame current value equal to or greater than a preset flame current value. Rotate 60.

The outlet 61 is provided with a plurality of louvers 61a. As shown in FIG. 5, the louver 61a is formed of a flat plate whose front side is curved downward, and a plurality of louvers 61a are arranged at equal intervals in the vertical direction of the outlet 61. The plurality of louvers 61a are attached to the main body 51 to form an air outlet 61, regulate the direction of warm air blown out from the air outlet 61, and prevent foreign matter from entering from outside. The lower edge of the outlet 61 is formed by a partition plate 62 that supports the combustion chamber 57.
In order to prevent that the warm air blown out from the outlet 61 rises to the upper part of the room and cannot heat the air in the lower part of the room, the outlet 61 is formed relatively below the front surface, and a plurality of louvers are formed. 61a is fixed to the outlet 61 in a state of being inclined horizontally or downward.

[0005]

However, in a conventional heating device such as a petroleum fan heater in which a plurality of louvers having the same shape are fixed to the outlet, the direction of hot air blowing from the outlet can be changed. Did not. For this reason, warm air is blown out horizontally or downward from the outlet in accordance with the fixing direction of the plurality of louvers, and as shown in FIG. Therefore, there is a problem that the temperature difference between the upper part and the lower part of the room becomes large.

[0006] Further, in the conventional heating apparatus, there is no sufficient consideration for extending the reach of the warm air blown out from the outlet, and in particular, a movable louver is provided due to cost and space problems. In a relatively inexpensive heating device such as an oil fan heater that cannot perform heating, the temperature difference between the upper and lower portions of the room cannot be reduced, and a wide range of the entire room cannot be brought into a comfortable temperature state.

Wind is released. Therefore, the warm air emitted from the upper part of the outlet goes obliquely upward.

(6) The inclined surface of the upper louver is inclined at an inclination angle of 4 to 6 degrees with respect to the horizontal direction.

In this configuration, the upper louver disposed above the outlet has an inclined surface inclined at 4 to 6 degrees with respect to the horizontal direction, and the upper part of the outlet is heated along the inclined surface of the louver from above the outlet. Wind is released. Therefore, the warm air discharged from the upper part of the air outlet goes obliquely upward at an angle of 4 to 6 degrees from the horizontal direction.

(7) The space between the upper louver and the lower louver is characterized in that the width in the vertical direction on the downstream side in the discharge direction of the warm air is smaller than the width in the vertical direction on the upstream side. . In this configuration, a hot air discharge path having a throttle portion is configured between the arrangement position of the upper louver and the arrangement position of the lower louver at the outlet. Therefore, the discharge speed of the hot air between the upper louver and the lower louver at the outlet is increased, and the distance over which the warm air discharged from the intermediate portion of the outlet reaches.

(8) The front end of the upper louver is located forward of the main body than the front end of the lower louver.

In this configuration, the amount of protrusion of the upper louver from the discharge port is made larger than that of the lower louver, and the warm air flows from the outlet to the position corresponding to the amount of protrusion of the louver forward in the prescribed discharge direction. Is released. Therefore, the discharge direction of the warm air discharged from the upper part of the outlet is defined to a position farther than the warm air discharged from the lower part.

1A and 1B are a front view and a side view showing the appearance of an oil fan heater which is a heating device according to an embodiment of the present invention. An oil fan heater 1 according to the embodiment of the present invention has a front surface of a main body formed by a front plate 2. In the front plate 2, an outlet 3 is opened near the center of the front surface, and an operation unit 4 is arranged at the upper part. A plurality of louvers 10 are arranged in the outlet 3 in the up-down direction. The operation unit 4 includes a switch that receives an operation operation of the oil fan heater 1, a display that displays an operation state, and the like. The top, side, and bottom surfaces of the oil fan heater 1 are constituted by an upper plate 6, a side plate 7, and a placing plate 5. A part of the outlet 3 is provided with a water supply window 19 for displaying the amount of kerosene stored in a fuel tank disposed inside the main body.

The internal structure and operation of the oil fan heater 1 according to this embodiment are the same as those of the conventional oil fan heater 51 shown in FIG.

FIG. 2 is a side sectional view of a main part showing the sectional shape and arrangement of the louver at the outlet of the oil fan heater. Five louvers 11 to 15 are arranged vertically in an outlet 3 formed in the front plate 2 of the oil fan heater 1. The two louvers 11 and 12 arranged above the outlet 3 are the upper louvers 10a of the present invention, and the three louvers 13 to 1 arranged below the outlet 3 are provided.
5 is a lower louver 10b of the present invention. Louver 11
Reference numeral 15 is attached via a louver frame 16 to the peripheral portion of the outlet 3 formed in the front plate 2. In addition, outlet 3
The lower edge portion substantially coincides with the upper surface of the partition plate 17 arranged inside the oil fan heater 1.

The louvers 13 constituting the lower louver 10b
15 have substantially the same cross-sectional shape. On the other hand, the louvers 11 and 1 constituting the upper louver 10a
Reference numeral 2 denotes shapes different from each other, and the louvers 13 to 15 also have different cross-sectional shapes.

That is, the louvers 13 to 15 constituting the lower louver 10b are, as an example,
The upstream side in the direction of discharge of hot air in the direction is a curved portion 13a that is convex downward, the downstream side is a substantially horizontal plane portion 13b, and the front end 13c that is the downstream end is bent in an arc shape. ing.

On the other hand, the louvers 11 and 12 constituting the upper louver 10a are composed of curved portions 11a, 12a and an intermediate portion 11a.
b, 12b, flat plate portions 11c, 12c, and front end portion 11
d, 12d. Curved portions 11a, 1
2a has a larger curvature than the curved portion 13a of the louver 13. The middle portions 11b, 12b are
It is constituted by a partial arc connecting the 12a and the flat plate portions 11c, 12c. The flat plate portions 11c and 12c correspond to the inclined surfaces of the present invention, and are inclined at an inclination angle of 4 to 6 degrees with respect to the horizontal direction, with the downstream side in the direction of discharging the hot air in the direction of arrow A upward. . The front ends 11d and 12d are bent in an arc shape. Portions downstream of the flat plate portions 11c and 12c and continuing to the front end portions 11d and 12d are curved upward.

In the upper louver 10a, the flat plate portion 11c of the upper louver 11 is longer than the flat plate portion 12c of the lower louver 12. Therefore, the front end 11 d of the upper louver 11 projects forward from the front end 12 d of the lower louver 12. In addition, the louver 12
Of the lower louver 10c projects forward from the front end of the lower louver 10c.

Since the louvers 11 to 15 are arranged at the outlet 3, the direction of discharge of the warm air passing through the outlet 3 passes through the discharge paths formed between the louvers 11 to 15, respectively. In the meantime, the flow is divided along the shapes of the louvers 11 to 15. In the upper louver 10a, the outlet 3 is not open above the louver 11 arranged at the uppermost part of the outlet 3, and the discharge path 21 between the louver 11 and the louver 12 extends from the upstream end to the downstream end. It has a substantially constant vertical width. In the lower louver 10b, the outlet 3 is not open below the louver 15 arranged at the lowermost part of the outlet 3, and the discharge path 23 between the louver 13 and the louver 14
The discharge path 24 between the louver 14 and the louver 15 also has a substantially constant vertical width from the upstream end to the downstream end. On the other hand, the discharge path 22 between the louver 12 of the upper louver 10a and the louver 13 of the lower louver 10b has a smaller vertical width at an intermediate portion. Note that the vertical width of the release path 21 is wider than the vertical widths of the release paths 22 to 24.

With the above configuration, the warm air heated inside the main body is supplied to the louvers 11 to 15 disposed in the outlet 3.
Are discharged into the room through the discharge paths 21 to 24 configured between them. Therefore, the hot air blown to the upper part of the outlet 3 is discharged to the front surface of the main body along the lower surface of the louver 11 and the upper surface of the louver 12 while passing through the discharge path 21. At this time, the discharge direction of the warm air is the flat plate portion 1 of the louver 11.
After being turned upward at 1c and the flat plate portion 12c of the louver 12, it is further turned upward by the front end portion 12d of the louver 12. However, since the front end 11d of the louver 11 located above the louver 12 is located ahead of the front end 12d of the louver 12, the emission direction turned upward by the front end 12a is suppressed by the front end 11d. . As a result, the warm air that has passed through the discharge path 21
The louver 11 reaches a far position in the emission direction defined by the cross-sectional shape of the louver 11.

The warm air blown to the intermediate portion of the outlet 3 is discharged to the front of the main body along the lower surface of the louver 12 and the upper surface of the louver 12 while passing through the discharge path 22.
As described above, the vertical width of the discharge path 22 is narrowed at the intermediate portion, and the vertical width on the downstream side in the discharge direction is smaller than the vertical width on the upstream side. Therefore, the warm air blown to the intermediate portion of the outlet 3 has a high flow velocity while passing through the discharge path 22, and the obliquely upper portion defined by the lower surface of the horizontal portion 12 c and the front end portion 12 d of the louver 12 and the louver 13 reaches a position far from the horizontal direction defined by the upper surface of the horizontal portion 13b.

Further, the warm air blown to the lower part of the outlet 3 passes through the discharge passages 23 and 24 while the louver 13
Along the upper and lower surfaces of the louver 14 and the upper surface of the louver 15 to the front surface of the main body. At this time, in the discharge path 23, the hot air discharged along the lower surface of the louver 13 is directed obliquely downward by the bent portion of the front end 13c, and the hot air discharged along the upper surface of the louver 14 is The light is emitted substantially horizontally by the flat portion 14b. In the discharge path 24, the hot air discharged along the lower surface of the louver 14 is directed obliquely downward at the bent portion of the front end portion 14 c, and the hot air discharged along the upper surface of the louver 15 is flat. It is emitted substantially horizontally by the part 15b. further,
In the middle of the discharge path 24, the vertical width on the downstream side in the discharge direction is wider than the vertical width on the upstream side.
The flow velocity of the warm air passing through 4 becomes slow. From these facts, the warm air blown to the lower part of the outlet 3 is discharged from the discharge path 23
And 24 are emitted slightly downward with respect to the horizontal direction. In addition, since the flow velocity of the warm air is lowered in the discharge path 24 located below, the reach of the warm air passing through the discharge path 24 is shortened.

The range occupied by the transport path 21 and the transport path 22 in the vertical range of the outlet 3 is wider than the range occupied by the transport path 23 and the transport path 24. Therefore, a larger amount of warm air passes through the transport paths 23 and 24 than the transport paths 21 and 22.

As described above, by arranging the louvers 11 to 15 in the vertical direction of the outlet 3 with different cross-sectional shapes and arrangements, the louvers 11 to 15 are provided at the outlet 3.
The warm air can be discharged in different discharge states in the discharge paths 21 to 24 formed between the louvers 11 to 15 without moving the louvers 11 to 15.

FIG. 3 is a diagram showing a temperature distribution in a room when the oil fan heater is used. As described above,
The warm air blown to the outlet 3 passes through the transport paths 21 to 24, so that the room temperature can be raised over a wide range of the room. When FIG. 3 is compared with FIG. 6 which shows the temperature distribution in the room when the conventional oil fan heater is used, the room temperature at a position farther obliquely above and in front of the oil fan heater 1 has risen. In the height range near the floor in front of the oil fan heater 1, the position where the room temperature becomes high is short. Therefore, in the oil fan heater 1 according to this embodiment, the room temperature can be more uniformly raised in a wider range of the room than in the conventional case, and a more comfortable temperature matching the needs of the user can be obtained. You can create an environment.

In the oil fan heater 1 according to the above embodiment, five louvers 11 to 15 are arranged at the outlet 3, but the number of louvers arranged at the outlet 3 is not limited to five. In the above embodiment, the lower louver 10b
Although the three louvers 13 to 15 forming the lower louver 10b have substantially the same cross-sectional shape, the plural louvers forming the lower louver 10b may have different cross-sectional shapes.

[0039]

The present invention has the following effects.

(1) An upper louver and a lower louver having different cross-sectional shapes are vertically arranged at an outlet for discharging warm air forward, and discharge is performed from the outlet according to the cross-sectional shapes of the upper louver and the lower louver. By discharging the warm air in the direction, the warm air can be discharged in different discharge states from the upper part of the outlet in which the upper louver is disposed and the lower part of the outlet in which the lower louver is disposed. Thereby, by taking into account the shape and the position of each of the plurality of louvers arranged at the outlet, the reach of the warm air can be extended without operating the louvers, and the temperature difference between the upper part and the lower part in the room can be increased. Can be reduced, and a wide range of the entire room can be brought into a comfortable temperature state.

(2) A plurality of louvers whose forward louvers have a larger forward protrusion amount are arranged vertically in the upper part of the outlet, from the upper part of the outlet to a position corresponding to the forward protrusion of the louver. By discharging the warm air in the discharging direction according to the cross-sectional shape of the louver, the discharging direction of the warm air discharged from the upper part of the outlet can be specified to a position farther upward.

(3) A single or a plurality of upper louvers having a slope inclined with the front end side upward are arranged above the outlet, and warm air is discharged from the upper part of the outlet along the slope of the louver. By doing so, warm air can be discharged obliquely upward from the upper part of the outlet.

(4) The upper louver disposed above the outlet has an inclined surface inclined at 4 to 6 degrees with respect to the horizontal direction.
By discharging the warm air from the upper portion of the outlet along the inclined surface of the louver, it is possible to discharge the warm air obliquely upward from the upper portion of the outlet by 4 to 6 degrees from the horizontal direction.

(5) By forming a hot air discharge path having a throttle portion between the position of the upper louver and the position of the lower louver at the outlet, the upper louver and the lower louver can be connected at the outlet. During the warm-up period, the distance over which the warm air discharged from the middle of the outlet reaches can be increased, and the room temperature at a farther position can be raised.

(6) The amount of protrusion of the upper louver from the discharge port is made larger than that of the lower louver, and warm air is discharged in a prescribed discharge direction from the outlet to a position corresponding to the amount of protrusion of the louver forward. Thus, the direction in which warm air is released from the upper portion of the outlet can be defined to a position farther than the direction in which warm air is released from the lower portion.
