Abstract

PURPOSE:To make a surface temperature uniform by eliminating partial high temperature part of a grill on a front surface of a room heater. CONSTITUTION:A petroleum warm air room heater for discharging high temperature gas generated by combustion together with the air from a blower, from a warm air supply outlet through a grill 13 on a front surface of the heater out of the heater, a high efficiency thermal conductor 15 is secured in close contact to a rear surface of a grill fin 13a at the end of the grill in the entire longitudinal direction of the grill. Since heat of a high temperature part is conveyed to a low temperature part by the conductor, generation of locally high temperature part at the grill is prevented, and its safety is enhanced.

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an oil hot air heater.

2. Description of the Related Art FIG. 2 is a side sectional view showing the main structure of an oil hot air heater. In the figure, 1 is the burner, 1a is the burner head at the tip of the burner 1, 2 is the combustion tube that houses the burner head 1a, 3 is the stand at the bottom of the heater, 4 is the blower installed on the back of the heater, 5 is the air There are two aisles, upper and lower, A.
A wind tunnel surrounding the combustion tube 2 configured in B, 6 a guide plate for adjusting air flow, 7 a main body case, 8 a case celestial body, 9 a front panel, 10 a blower cover, 11 an air intake port, 12 is the hot air outlet at the front of the heater. Further, 13 is a grill provided at a constant interval on the front surface of the heater to cover the hot air outlet 12, and 13a is a grill fin at the tip of the grill.

FIG. 3 is a perspective view showing the external appearance of the oil hot air heater shown in FIG. In the figure, the same reference numerals as in FIG. 2 indicate the same parts. In the figure, the part indicated by the broken line is the location where the hot air outlet 12 is located, and 14 is the operation panel.

[0004] In this oil hot air heater, a gas mixture of vaporized kerosene gas and air that has entered the burner 1 is ejected from the burner head 1a into the combustion tube 2, where it is ignited and burned to generate high-temperature gas. . This high-temperature gas mixes with the cold air pushed in from the blower 4 to become hot air, which is sent through the wind tunnel 5 to the hot air outlet 12 and discharged outside the machine via the grill 13 to heat the room. . Note that the air coming through the upper stage A of the wind tunnel 5 has a higher specific gravity than the warm air coming through the lower stage B of the wind tunnel 5, which prevents the warm air from rising immediately after coming out of the hot air outlet 12. Preventing.

[0005]

[Problems to be Solved by the Invention] However, in the conventional oil hot air heater, since there is a combustion tube 2 behind the hot air outlet 12 in the center thereof, the wind force from the blower 4 is smaller than in other parts. The surface temperature of the grill 13, particularly the grill fins 13a, is high in the center and low in other parts, and the temperature gradient is large, posing the risk of burns in the high temperature parts.

[0006] This invention was made to solve the above-mentioned problem, and it is possible to obtain a highly safe oil hot air heater by eliminating the local high-temperature parts of the grill fins and making the surface temperature uniform. The purpose is to

[0007]

[Means for Solving the Problems] This invention discharges high-temperature gas generated by combustion in a burner section together with air from a blower from a hot air outlet to the outside of the machine through a plurality of grills provided in the front of the heater. In the oil hot air heater, a highly efficient thermal conductor is closely fixed to the back surface of the grill fins at the tip of each grill over the entire longitudinal direction of the grill.

[0008]

[Operation] In this invention, the highly efficient heat conductor transfers heat from the high temperature area to the low temperature area, thereby making the surface temperature of the grill fins uniform over the entire length of the grill.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing an example of the structure of a grill portion of an oil hot air heater according to the present invention. In the figure, 13
13a is a grille, and 13a is a grille fin having a wrap-around end portion of the grille. A heat pipe 15 is a highly efficient heat conductor, and is fixed to the back surface of the grill fin 13a in close contact with the entire length of the grill 13. Further, the heat pipe 15 is installed so that its evaporating portion is located at a portion facing the combustion tube, and its condensing portion is located at a portion away from the portion facing the combustion tube. In this embodiment, five grills 13 are attached to the mounting plate 16, and heat pipes 15 are also attached to each grill. Note that the structure other than this grill portion is the same as that of the conventional example shown in FIGS. 2 and 3.

[0010] When the oil hot air heater having the above configuration is used, even if the temperature of the grill 13 at the hot air outlet and facing the combustion tube rises, the heat is transferred to the heat pipe 1.
5 to a lower temperature area, the surface temperature of the grill fins 13a is kept substantially uniform at any location in the longitudinal direction. Therefore, grill fin 1
This occurs when a specific part of 3a becomes extremely hot.
No more burns etc.

[0011]

[Effects of the Invention] As explained above, according to the oil hot air heater of the present invention, a highly efficient heat conductor is closely fixed to the back surface of the grill fin at the tip of the grill over the entire longitudinal direction of the grill. , the surface temperature of the grill fins is made uniform over the entire surface, preventing the occurrence of extremely high temperature areas, and increasing safety when using the heater.
