Abstract

PURPOSE:To shorten the distance between hot air blow-off ports and a space to be warmed, rapidly warm the entire part of the room, spare space energy and improve comfortableness by providing hot air blow-off ports around the entire periphery of the lower part of the space heater main body. CONSTITUTION:Cool air within the room is sucked up into a main body 11 by the rotation of a fan 13 from the upper part thereof and flows downward of the main body 11. Cold air is warmed at a combustion cylinder 15 by heat generated in a combustion burner 14 and a high temperature exhaust gas, and converted into a hot air flow and further flows downwardly. How air flowing downward changes its direction toward the horizontal direction in its entirety by a hot air flow guide 16 and is discharged within the room through hot air blow-off ports 17 provided around the entire periphery of the lower part of the main body 11 to warm the interior of the room.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a convection type heater.

BACKGROUND OF THE INVENTION In recent years, convection type heaters equipped with fans are rapidly becoming popular, and various energies such as oil, gas, and electricity are used as heat sources.

Hereinafter, an example of the conventional heater mentioned above will be explained with reference to the drawings.

Figure 2 shows a conventional convection heater;
In the figure, 1 is a combustion burner where gas, oil, etc. are burned. Reference numeral 2 denotes a combustion cylinder for mixing high-temperature exhaust discharged from the combustion burner 1 with air. 3 is a fan, and as the fan 3 rotates, it sucks in indoor air as combustion air and mixing air from the rear of the appliance (right side in Figure 2), and transfers it as warm air to the front of the appliance (Figure 2). (left side). 4 is a hot air outlet,
Reference numeral 5 designates an instrument main body case, 6 a filter attached to a static electricity suction lower provided on the rear surface of the instrument main body case 5, and 8 a fan case.

The operation of the heater configured as above will be described below.

Gas or oil is supplied to the combustion burner IIC, which is ignited with an igniter or the like to start combustion and continue to generate high-temperature heat. The generated high-temperature air mixes with the indoor air sucked in from the air suction port 5a by the rotation of the fan 3 while passing through the inside of the combustion tube 2, and then passes through the fan 3. The hot air is then released as warm air from the hot air outlet 4.

Problems to be Solved by the Invention However, in the above conventional configuration, the hot air outlet 4
is fixed in one direction at one location on the lower side of the device body case 75. Therefore, in order to heat the entire room, the device must be placed near the wall. Because it takes time to create a uniform and comfortable space, it consumes a lot of energy.The present invention solves these conventional problems, and aims to To provide a heater capable of quickly creating a comfortable space by blowing hot air in a direction, thereby saving energy and improving comfort.

Means for Solving the Problems In order to solve the above-mentioned problems, the heater of the present invention is provided with hot air outlets all around the lower part of the main body.

Function According to the above configuration, the hot air outlet is provided all around the lower part of the main body, so if this heater is installed in the center of the room and hot air is blown out in the lower part of the main body all around, the warm air will be Since the distance between the air outlet and the space to be heated is shortened, the entire room can be quickly heated.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In FIG. 1, reference numeral 11 denotes the main body of the heater, and a drive motor 12 and a fan 13 rotated by the drive motor 12 are mounted downward on the lower surface of the top plate 11a of the main body 11.

Further, below the drive motor 12 and fan 13, a combustion burner 14 and a cylindrical combustion cylinder 15 covering the combustion burner 14 are fixedly fixed. Further, this combustion tube 15 is provided with a cut-and-raised portion 15a extending outward all around the circumference. Further, at the lower part of the combustion tube 15, a warm air guide 16 is provided over the entire circumference to change the direction of the hot air generated by the cold air from the fan 13 above being heated by the combustion tube 15 in a horizontal direction all around the circumference. There is. Further, the main body 11 is provided with a hot air outlet 17 that blows out hot air all around the lower part.

The operation of the above configuration will now be described.

Cold indoor air is sucked into the main body 11 from the upper part of the main body 11 by the rotation of the fan 13, and flows below the main body 11. The cold air is then sent to the combustion burner 14.
The combustion tube 15 is heated by the heat generated by the combustion chamber 15 and the high-temperature exhaust gas, and becomes warm air that flows further downward. The hot air flowing downward changes its direction in the horizontal direction around the entire circumference by a hot air guide 6 provided at the bottom of the main body 11, and then is directed through a hot air outlet 17 provided at the entire bottom of the main body 11. It is released into the room and warms the room.

Effects of the Invention As described above, according to the present invention, since the hot air outlet is provided all around the lower part of the main body, this heater is installed in the center of the room, and hot air is directed all around the lower part of the main body. When hot air is blown out, the distance between the hot air outlet and the space to be heated becomes shorter.
It is possible to quickly heat the entire room, thereby saving energy and improving comfort.
