Abstract

(57) [Summary] [Purpose] The purpose is to guide the stench generated when the oil fan heater is extinguished to the deodorizer so that it will not be blown to the front, and to make it comfortable air to be discharged from the rear outlet. [Composition] At the same time as extinguishing the fire, the combustion blower motor, which has a forward and reverse rotation function, is reversed for several seconds. As a result, the incompletely combusted gas with a bad smell is guided to the deodorizer installed near the rear air supply port so that it does not blow out to the front panel of the oil fan heater, and passes through the deodorizer to create a comfortable air flow. And then released.

Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a deodorizing device of an oil fan heater for extinguishing an odor generated when extinguishing a fire.

 (Prior Art) Generally, the structure of the combustion part of an oil fan heater is a blower motor A for combustion, a fan B, a pump D for pumping kerosene, a pipe needle E, a combustion heater F, an ignition plug G for ignition, and a combustion engine. It is composed of an air supply port H that takes in the air, a combustion ring I, a cap J, a flame lot K, and a preheating thermistor L.

 The operating principle is to press the operation switch to perform ignition operation. First, the preheater F is energized. When the heater reaches 250 degrees after energization, the preheat thermistor L detects it and energizes the blower motor A. An air flow is generated by the blower fan B, the indoor air is taken in from the air supply port H, enters the combustion heater unit F through C, and is discharged outside together with residual gas that may be generated by being heated to 250 degrees. It This operation is called prepurge. After the pre-purge, the electromagnetic pump D, the ignition plug G, and the blower motor M are also energized. The fuel (kerosene) pumped up from the electromagnetic pump D is mixed with the air from C through the pipe and the needle E and enters the heater section F.

 The gaseous fuel starts to burn by the spark plug. The burned heat is released into the room by the blower fan M. By the way, the principle of operation during extinguishing is to turn off the power switch. At the same time, the electromagnetic pump D stops and the heater F also stops energizing. However, the blower motor M and the combustion motor A are energized even when the power is off. The reason is that the blower fan M operates due to the cooling effect of the combustion section and effective utilization of heat. On the other hand, the blower motor A is forcibly operated because the fuel (kerosene) left in the tip of the heated needle E drips into the heater F to release incomplete combustion gas outside the oil fan heater body. I am letting you. This is called post-page. The weak point of the conventional structure is that the post-purging required for this safety causes an unpleasant odor. By the way, in order to solve this problem, each manufacturer (1) made a large ring and greatly improved the contact surface. (2) A catalyst is installed at the bottom of the heater to make the residual gas close to complete combustion. But it's not perfect yet. Because, as long as the post-purge is blown out in front of the oil fan heater, the complete deodorizing effect cannot be expected.

 (Problems to be solved by the invention) The present invention does not prevent dropping of the residual kerosene in the needle at the time of extinguishing the fire itself, but also provides a mechanism for completely burning the dropped incomplete combustion gas. Instead, before the incomplete combustion gas generated after dropping is discharged to the outside of the combustion cylinder, the flow direction of the post-purge is directed to the air supply port H direction and before the air supply port exits the air supply port H 1, The purpose of this device is to pass the deodorizing device provided nearby to discharge the deodorized air to the rear part of the main body. By the way, there are two situations where the post-purge works. One is when the room temperature reaches the optimum temperature set by the user, and the other is when the user extinguishes the fire by himself without the need to keep warm.

It is in the second situation that it is especially uncomfortable when extinguishing a fire. In other words, if the person who extinguished the fire can jump out to the doorway like Paru and the door at the same time as the fire extinguishing, there is no problem. As a result, the user pushes the fire extinguishing switch, and at the same time, an unpleasant odor is emitted to the front.

Therefore, the conventional oil fan heater directly gives people uncomfortable feeling.

On the other hand, the mechanism provided by the present invention is intended to be processed behind the machine rather than being blown out to the front, and therefore depends on the performance of the deodorizer. The point that the nose of the robot faces away from the machine is different from the direct discomfort of conventional mechanisms.

 (Means for solving the problem) 1. In order to direct the post-purge toward the air supply port H, the blower motor A needs to be reversely rotated for several seconds when extinguishing the fire. In other words, the combustion blower motor A of the present invention is equipped with one having a forward and reverse rotation function.

 2. Install a deodorizer near the air supply port.

 3. The electricity deodorizer is energized only during post-purge. Therefore, it should be installed in the air supply port.

 4. However, an odor filter or a deodorizer that deodorizes by a chemical reaction must have an exhaust port separately from the air supply port. That is, guide plates (1) and (2) that slide between (3) and (4) with O as a fulcrum are provided. An odor filter is installed inside the exhaust port.

 (Operation) Turn off the power switch artificially. Alternatively, when the room temperature reaches the temperature set by the user, the power is turned off and the electromagnetic pump is de-energized. At the same time, the combustion blower motor A rotates in the reverse direction. The fan B fixed to the shaft of the motor also starts reverse rotation.

The air in C and the air in the combustion heater move in the H direction through C. If you use electricity to deodorize, the deodorizer is energized at the same time. As shown in Fig. 2, the air supply port changes to an exhaust port. The deodorized air is discharged indoors through the exhaust port.

On the other hand, filters and deodorizers that cause chemical reactions cannot be installed inside the air supply port. This is because the deodorizing function is not necessary for air supply. Therefore, as shown in Fig. 3, when the oil fan heater is burning, the guide plate (1) at the fulcrum O moves to the position of the stopper (3), but when post-purging occurs, the guide plate (1) becomes ( It moves to the stopper of 4) and stops, and the air supply port is closed. On the contrary, the guide plate (2) moves to the stopper of (3). In other words, it will be in an open state and will serve as an exhaust port. The incomplete combustion gas that has moved by the reverse rotation of the blower motor A fan B absorbs the component that is the source of the unpleasant odor in the deodorizer in (B) and is released to the outside.

 (Examples) Various examples of the present invention will be described with reference to the drawings.

First Embodiment As shown in FIG. 4, this is a deodorizing device mounted on the machine body.

Second Embodiment As shown in FIG. 5, this allows the device of the first embodiment to be installed as an option.

Third Embodiment A deodorizer using electricity is attached to the inside of the air supply port and energized only during post-purge.

Fourth Embodiment The apparatus of the third embodiment can be installed in the machine body as an option.

Fifth Embodiment Although the structure is the same as that of the first embodiment, the difference is that the deodorizer is equipped with an electric deodorizer.

 (Effect of the device) Since the post-purge after extinguishing the fire is not blown out to the front panel, the effect of removing an unpleasant odor is great. Moreover, the mechanism of the present invention is inexpensive.
