Abstract

PURPOSE:To contemplate facilitated lever actuation for up and down adjustment of wick in fuel oil combustion apparatus, by removing, upon ignition operation, a pressure resistance applied by a pressure member which prevents falling of wick due to the tare. CONSTITUTION:A lever unit comprises a centrally bored bearing 12, fire ceasing plate 13 fixedly attached on the bearing 12, a pressure member 14 compressed by and behind the plate 13, a lever 15 rotatable around the bearing 12 under appropriate pressure resistance applied by the pressure member 14 for an up and down movement of wick, and an ignition lever 16 which is freely rotatable around the bearing 12. The lever unit is supported by a base member 17 which comprises a shock-proof automatic fire ceasing mechanism and a shaft on which the bearing 12 is rotatably mounted. Upon depressing the ignition lever 16, the lever unit 11 rotates, together with the bearing, around the shaft 21 of the base member 17 without influence of the pressure member 14, to thereby accomplish facilitated actuation thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an oil combustor having a wick that is movable up and down.

Conventional Technology Generally, this type of oil burner uses a wick to burn kerosene for heating, etc., but recently, as shown in Figures 6 and 7, the upper and lower ends of the wick are connected to the wick up/down lever 1. You can see a lot of things going on.゛In this type, a pressurizing body 3 is installed to provide resistance between the wick lever 1 and the fire extinguishing board 2 so that the wick containing kerosene does not fall due to its own weight during combustion. It is designed to prevent

Problems to be Solved by the Invention However, in this type, the core up/down lever 1, the pressurizing body 3, the fire extinguishing plate 2, as well as the base plate 6 and stop plate 6 are set on one shaft part 4. Since the pressure of the pressurizing body 3 is applied to the parts, more force than necessary is required for the fire extinguishing spring 7 that is biased against the fire extinguishing board 2, and the force to set the wick to the combustion position is twice as much as the applied pressure. There was a problem with it being heavy.

The present invention solves such conventional problems by making the pressurizing force (resistance) by the pressurizing body act only when the lamp wick falls under its own weight, reducing the load on the fire extinguishing spring, and reducing the load on the lamp wick set. The purpose of this is to reduce the amount of operating force required.

Means for Solving the Problems In order to solve the above problems, the oil combustor of the present invention unitizes only the wick up/down lever, the pressurizing body, and the fire extinguishing plate into a bearing part, and this lever unit is attached to the shaft of the base plate part. Department KI! ! This is a two-axis support configuration in which the two shafts are supported together.

Effects of the present invention With the above configuration, the pressurizing body prevents the weight of the wick from falling during combustion, and the two-piece shaft reduces the operating force, resulting in a safe and comfortable operation. Allows you to obtain an oil burner.

EXAMPLES Below, examples of the present invention will be explained with reference to the attached FIGS. 1 to 4. Fig. 1 is a sectional view of the main parts of the present invention, Figs. 2 to 4 are state diagrams of the core vertical mechanism, Fig. 2 is a side view before combustion starts, and Fig. 3 is a side view in the combustion state. Figure, 4th
The figure is its back view. In the figure, 11 is a lever unit, which includes a bearing part 12 with a hole in the center, and a lever unit 12.
A fire extinguishing plate 13 fixed to one side of the extinguishing plate 13, a pressurizing body 14 compressed by the extinguishing plate 13, and a pressurizing body 14 that is pressurized by the pressurizing body 14 and can freely rotate around the outer periphery of the bearing part 12 with an appropriate feeling of resistance. It consists of a moving core up/down lever 16 and an ignition lever 16 that rotates around the outer periphery of a bearing part 12 without resistance. Reference numeral 17 denotes a base plate supporting the lever unit 11, which includes a weight 18 and a sensing lever 19.
, a seismic automatic fire extinguishing device consisting of a chain 20, etc., and a shaft portion 21 that rotatably supports a hole in a bearing portion 12 of the lever unit 11. A fire extinguishing spring 22 is installed between the fire extinguishing plate 13 and the base plate 17.

23 is a fire extinguishing bottle that is attached to the fire extinguishing plate 13, and is held by the hook portion 19a of the sensing lever 19 during combustion, and is held by a fire extinguishing spring 22.
It is designed to receive the power of U is a return spring for returning the ignition lever 16, and 26 is a spring that can be moved up and down inside the tank.
The lamp wick has upper and lower pins 26. Reference numeral 27 denotes a wick up/down axis, to which a wick up/down arm 28 is fixed, and the lamp wick 25 is moved up and down from the wick up/down arm 28 via a wick up/down pin 26. The core vertical shaft 27 is supported by a shaft metal fitting 29 on one side and a bearing metal fitting 30 on the other side, and has an arm portion 31 and a pin portion 32 on the side of the core vertical lever 16, and the pin portion 32 allows the core vertical lever 16 to be supported. It is connected to. Reference numeral 33 denotes a lever guide plate that guides the vertical rotation of the core vertical lever 16 and the ignition lever 16 of the lever unit 11.
K is designed to restrict lateral movement so that it does not come off.

In the above configuration, the operation of the present oil combustor will be explained. First, by pushing down the tip of the ignition lever 16, the core upper and lower levers 15 simultaneously rotate, and the lower end of the core upper and lower levers 15 presses the lower protrusion (not shown) of the fire extinguishing board 130, causing the fire extinguishing board 13 to rotate at the same time. .

That is, the lever unit 11 is connected to the base plate 1 together with the bearing 12.
It rotates around the negative part 21 of 7. Therefore, the pressurizing body 14
The pressing force does not act on the lead up/down lever 15 at all, and the lead up/down operation can be performed easily. - Rotation of the square vertically moving bar 150 causes the core vertical shaft 27 connected to the end of the core vertical lever 16 via the pin portion 32 and the core vertical arm 28 fixed to the core vertical shaft 27 to rotate; Push up the wick upper and lower pins 26 to raise the lamp wick 26. When the lamp wick 26 rises to the ignition position, the ignition lever 16 activates an ignition device (not shown) to ignite the lamp, and the extinguishing board bottle 23 is locked to the hook portion 19a of the sensing lever 19. At this time, fire extinguishing spring 2
2 is in a state where sufficient force is generated to lower the lamp wick 26 to the extinguishing position.

The wick 25 in the casing becomes heavy due to the kerosene contained therein, and the wick 25 itself always tries to fall downward, so the pressurizing body 1 is used to prevent this.
4 provides resistance to the wick up/down lever 16 and keeps the wick 26 in a constant position at all times.

When extinguishing a fire due to an earthquake, fall, etc., the weight 18 falls down and the chain 20 pulls up the sensing lever 19 and hook part 19a.
By removing the fire extinguishing pin 23 from the fire extinguishing spring 22
The wick 25 is lowered through each part with zero force to extinguish the fire.

According to the present invention, as is clear from the description of the embodiments above,
The lever part is made into a unit and supported by the base plate, so it is easy to use when operating the ignition.

Since the parts rotate as one and are not subject to resistance from the pressurizing body, it can be operated with less force than before, and when extinguishing a fire, the force of the fire extinguishing spring can be effectively transmitted to the wick without loss. can. Furthermore, the present invention has the advantage that it is not necessary to arrange the lever guide plate and the arm part of the core vertical axis on the side opposite to the base plate part of the lever unit to provide a lever, and the ease of assembly can be improved.
