Abstract

PURPOSE:To reduce noises and achieve cost-reduction at the same time by forming as one body a recessed section at a suitable position in the tank wall, providing a through-hole which communicates with the inside of the tank at the recessed section, and constituting an odor absorption device by closing the recessed section with a lid and installing a fan and motor on a plate body which has an exhaust opening at a suitable position of a plate body and forming the wall of the recessed section as part of the fan case. CONSTITUTION:The recessed section 17 provided in the upper face of a tank 11 is formed as one body so as to project to the inside of the tank, and in its bottom face a through-hole 18 is formed which communicates with the inside of the tank 11. A plate body 19 is installed on the circumferential stepped pressing section 17a of the recessed section with a packing 20 placed between, and the fan 21 of an odor absorption device 16 and a motor 22 are installed on the plate body. The plate body 19 forms at a suitable position in the circumferential section of the plate body an exhaust opening 23 which is tilted downwards toward the center, and the fan 21 is fixed to the upper wall face of the tank 11 by small screws in order to set the fan in the recessed section 17. The fan 21 of the odor absorption device 16 is surrounded dually by the wall of the tank 11 and the wall of the recessed section 17 so that the sound of rotation of the fan 21 is shielded. The recessed section 17 of the tank 11 becomes a part of the fan case which surrounds the fan 21, making a resin case surrounding the lower section of the fan 21 unnecessary, and the cost for the resin case is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a wick type oil burner such as an oil stove.

Conventional technology In general, wick-type oil combustors have the problem that when the wick is lowered to extinguish the fire, the oil vapor that continues to evaporate from the wick enters the high-temperature combustion cylinder, where it is thermally decomposed and generates a strong odor. Ta.

Recently, in order to reduce the odor caused by extinguishing a fire, a system has been developed that operates an odor absorbing device such as a fan at the same time the fire is extinguished, sucking the petroleum vapor that continues to evaporate from the wick into the tank and then releasing it to the outside. . Anne 3 starts rotating, wick 1
Petroleum vapor continues to evaporate from the top to tank 4 as shown by the arrow.
It is sucked inward and discharged to the outside through the discharge port 5.

According to this wick-type oil combustor with an odor absorbing device, the petroleum gas that continues to be produced after extinguishing the fire does not flow into the high-temperature combustion tube 6, but is released into the atmosphere through the tank 4, so that the petroleum vapor is thermally decomposed. The irritating odor caused by this process is eliminated, and the odor can be significantly reduced.

Problems to be Solved by the Invention However, when such an odor absorbing device is provided, a problem arises in that the rotational sound of the fan 3 leaks outside during the odor absorbing operation and generates a U sound. Furthermore, the provision of the odor absorbing device 2 also created the problem of significantly increasing costs. In particular, the case 2a of the odor absorbing device 2 must be made of oil-resistant and expensive resin, which is one of the causes of increased costs.

The present invention is intended to solve these problems, and its purpose is to reduce noise and cost at the same time.

Means for Solving the Problems In order to achieve the above object, the present invention includes a tank having a lamp wick that can be moved up and down, and an odor absorbing device that sucks vaporized gas from the upper part of the lamp wick through the inside of the tank. The tank has a recess projecting inward from the tank integrally formed in a suitable position on the tank wall above the oil level in the tank, and a through hole communicating with the inside of the tank is provided in a part of this recess, and the odor absorption device is installed in the recess. A fan and a motor for driving the fan are attached to a plate body that is closed and has an exhaust opening in a proper place, and the fan is installed so as to be located in the recess, and the wall of the recess is made into a part of the fan case. This is the configuration.

Function The present invention has the above-described configuration so that the fan is located inside the tank, so the rotation sound of the fan is doubly insulated by the wall of the tank, reducing the noise, and also making it possible to reduce the noise from the fan case. Since the part is formed by using the wall of the recess formed in the tank, a corresponding resin funky song is not required, and costs can be reduced.

Embodiment Below, one embodiment will be explained with reference to the drawings.
In Fig. 2, 1] is a tank, 12.13 is an inner and outer wick guide tube provided at the upper part of this tank 11, 14 is a wick whose lower part is immersed in oil in the tank 11, and the upper part is a wick. It is provided so as to be movable up and down so that it can freely move in and out of the combustion tube 15 through the guide tubes 12 and 13.

16 is an odor absorbing device attached to the upper surface of the tank 11;
This odor absorbing IT part will be explained in detail below using FIG.

In FIG. 1, reference numeral 17 denotes a recess provided on the top surface of the tank 11, which is integrally formed by press molding so as to protrude inside the tank, and a through hole 18 communicating with the inside of the tank 11 is formed in the bottom surface of the recess. be. Reference numeral 19 denotes a plate body placed on the peripheral stepped portion 17a of the recessed portion via a gasket 20, to which a fan 21 forming the main body of the odor absorbing device 16 and a motor 22 for driving the fan 21 are attached. This plate body 19 has an exhaust opening 23 at a suitable position on its peripheral edge and is formed to be inclined downward toward the center.The plate body 19 is screwed to the upper wall of the tank so that the fan 21 is located in the recess 17. It is.

In the above configuration, the fan 21 of the odor absorbing device 16 is located inside the tank 11 and is surrounded by the wall of the tank 11 and the wall of the recess 17. Therefore, the sound of the fan 210 rotating is insulated by this double wall. Further, the recess 17 of the tank 11 becomes a part of the fan case surrounding the fan 21, and the conventional resin case surrounding the lower part of the fan 21 is no longer necessary, resulting in cost reduction. In other words, since the recess 17 surrounding the lower part of the fan 21 is formed by press-molding the tank 1, no new material is required, and the only expensive resin required is the upper plate 19 that covers the fan 21. Since this plate body 19 is a simple plate, a complicated molding die is not required, and a large cost reduction can be achieved.

In addition, in this odor absorbing device 16, when the lamp wick 14 is lowered to extinguish the fire, the motor 22 starts rotating, and the motor 22 starts rotating for a predetermined period of time, e.g.
After a few seconds, it will stop rotating. During this time, the fan 21 rotates, sucking the petroleum vapor that continues to vaporize from the top of the wick through the through hole 18 through the tank 11 as shown by the broken line arrow, and exits it from the opening 23 provided in the plate 19 to the outside outside the combustion tube. Exhaust air will greatly reduce odors. At this time, the petroleum vapor sucked into the fan 21 touches the inner surface of the plate 19, which has a relatively low temperature, and a portion of it condenses, but this condenses along the slope of the plate 19 and collects in the center and continues downward. Flowing down. Therefore, the gasket 20 on the periphery of the plate body 19
This makes it possible to prevent problems such as particles gathering in certain areas and seeping out from these areas.

Effects of the Invention As is clear from the description of the embodiments, according to the present invention, it is possible to achieve a significant reduction in noise by doubly insulating the rotational sound of the fan, and at the same time, it is possible to reduce costs by saving materials for the fan case. We offer inexpensive and high quality wick type oil combustors! Ru.
