DETAILED DESCRIPTION OF THE INVENTION The present invention relates to heating equipment such as oil stoves, and in particular,
This relates to safety devices to prevent accidents such as fires.

For heating equipment such as kerosene heaters, which have one side open and obtain a heating effect mainly through radiant heat from the heat generating part, if the open side that dissipates radiant heat is brought close to a wooden or cloth-covered wall, etc. There is a risk of burning the walls or causing a fire.

Conventional heating equipment of this type is designed with a small distance between the heat generating part and the outer wall of the main body case in order to downsize the equipment and reduce transportation costs. No preventive measures were in place. The present invention has been made in view of the above points, and
A heating device is provided in which a restrictor is projected in front of the device to ensure a safe distance from a combustible wall or the like when the heat generating portion generates heat.

Hereinafter, embodiments will be described in detail with reference to the drawings. Figure 1~
FIG. 9 shows one embodiment of the present invention, in which 1 is a side wall constituting three sides of the main case of a kerosene stove, 2 is a top plate, 3 is a stand, 4 is a front door, and 5 is a guard attached to the opening B, and these constitute a box-shaped main body case A.

An oil tank 6 consisting of a lower tank 6a and an upper tank 6b is housed inside the main body case A, and the lower tank 6a has a wick outer cylinder (burner) that guides the outer circumference of the lamp wick 7 and supplies combustion air. It is equipped with 9. Furthermore, the core guide tube 8 and the core outer tube 9
is equipped with a combustion tube 10. Reference numeral 11 denotes a wick up and down knob for moving the lamp wick 7 up and down, and 12 is a wick holder fixed to the lamp wick 7 and having a rack, which is interlocked with a wick adjustment shaft 13 having a pinion 13a. Reference numeral 14 denotes a wick lowering spring that acts to constantly lower the wick 7.

15 is a sensing weight that operates during earthquakes and falls; 16
Activate the sensing lever.

17 is a gear fixed to the core adjustment shaft 13, and the sensing lever 1
The position of the lamp wick 7 is regulated by the claw 16b of 6.

18 is an extinguishing button that activates the sensing lever 16 and lowers the lamp wick 1. Reference numeral 19 denotes an operating metal fitting, 20 a regulating member that allows the operating metal fitting 19 to slide up and down, 21 a guide fitting that guides the sliding movement of the actuating metal fitting 19, and 22 a constant operating metal fitting 1.
This is a set spring that acts to pull down 9.

Reference numeral 23 denotes a regulation guide fitting that guides the sliding movement of the regulation tool 20, and this regulation guide fitting 23 is fixed to the mounting base 3.

Further, reference numeral 24 denotes a reflector plate provided at the rear of the combustion tube 10 to reflect radiant heat forward. The regulating device 20 is made by processing a wire rod with a circular cross section into the shape shown in FIG.
The part 0b is passed through the inside of the regulation guide fitting 23,
In addition, an operating metal fitting 19 is located at the front of the device continuously.
Regulates vertical sliding.

The portion 20a is connected to the actuating fitting 19 by sliding the actuating fitting 19.
The tip of the sensor lever 16 is positioned above 20b by a distance x necessary to push the sensing lever 16 upward. ing.

Further, the rear end of 20b is bent, and the bent portion 20c and the rear end of the restriction guide fitting 23 serve as a stopper to prevent the restriction tool 20 from moving forward by more than a certain distance. Figures 3 to 6 show the restrictor 20 and operations related to its movement. In normal use, the restrictor 20 is pulled out to the front of the device, as shown in Figures 3 and 6. The actuating metal fitting 19 linked to the part 20b of the regulating device 20 is pulled down by the action of the set spring 22, and the upper tip of the actuating metal fitting 19 is connected to the da sensing lever 16.
It is set at a position with a gap y from the bottom surface of the .
However, as shown in FIGS. 4 and 5, when the restrictor 20 is pushed into the device, the lower end of the actuating fitting 19 is located at a portion 20a that is one step higher than 20b of the restrictor 20 by the dimension x, so that it is activated. The metal fitting 19 moves upward (direction c),
The upper end face lifts the sensing ν bar 16, thereby causing the pawl 16b to separate from the gear 17. As a result, the lamp wick 7 descends and enters a non-burning state, that is, an unusable state.
In addition, the operating metal fitting 19 when the regulating device 20 is pulled out,
Regarding the distance z from the end of the part 20a that is raised by the dimension x of the restrictor 20 (see Figure 6) and the length e of the part 207a, the combustible wall, etc. is restricted due to the influence on the combustible wall, etc. of the equipment. The dimensions are such that even if the tip of the ingredient 20 is approached, it will not burn or catch fire.

In the above configuration, when normally used, as shown in Figure 6, pull out the regulator 20 forward, then pour kerosene into the oil tank 6, turn the wick up/down knob 11 to raise the wick 7, and ignite. Combustion begins when ignited by a device (not shown).

Part of the heat radiated from the combustion tube 10 is directly radiated in the direction of the opening B at the front of the equipment, and the heat radiated backward is reflected by the reflector plate 24 and directed toward the opening B, and is radiated. Heating is done. In addition, in this kerosene stove, even if the opening B side is brought close to the combustible wall, the tip of the restrictor 20 will hit the wall due to the protruding dimension of the restrictor 20 from the front of the device, and the combustion tube 10 and the wall will be separated by a safe distance. It is safe and does not cause the wall to burn or catch fire. On the other hand, when storing this kerosene heater in a packaged reseason, by pushing the restrictor 20 into the equipment,
Becomes compact. In this state again, the restrictor 2 is in use.
When a force is applied toward the device and the distance between the combustible wall and the device becomes less than the safe dimension, the raised part 20a of the restrictor 20 and the actuating metal fitting are removed as shown in Figures 4 and 5. 19
As a result, the sensing lever 16 is pushed up, the pawl 16b of the sensing lever 16 is disengaged from the gear 17, and the lamp wick 7 is lowered. This makes it unusable. When in use, the restrictor 20 must be pulled out by a distance e that does not expose the combustible wall to thermal influence, so the above-mentioned safety can be achieved. FIGS. 10 and 11 show another embodiment of the present invention. In this embodiment, the safety barrier between the equipment and the combustible wall is established by rotating the restrictor 25 and tilting it toward the front of the equipment. This was done to ensure distance.
The restrictor 25 is a wire rod with a circular cross section, and is processed into the shape shown in FIG.
It is rotatably supported on a mounting table 3. This restrictor 25
One end 25a has an upwardly curved shape and is inserted into an elongated hole 27a at the lower end of a movable fitting 27 that is fixedly interlocked with the extinguishing button 18 that operates the sensing lever. During normal use, the restrictor 25 falls down in front of the device under its own weight.
At that time, the movable fitting 27 is moved upward by the movement of the end portion 25a, and the fire extinguishing button 18 is positioned upward. When a safe distance cannot be maintained between the end portions 25a and 25a, the limiter 25 moves in the f direction and the end portion 25a
moves in the g direction, pulls down the moving metal fitting 25, and pulls down the extinguishing button 18 that is linked to the sensing lever 16.
make it unusable. This embodiment not only improves safety, but also makes it more compact when the kerosene heater is packaged or stored in the off-season by rotating the restrictor 25 upward and bringing it closer to the front of the appliance. Although the above description has been made using an example of a kerosene stove, the present invention can be applied to any type of heating equipment, such as gas or electric heating equipment.

As explained above, according to the present invention, since the restrictor protrudes forward from the opening of the main body case, a safe distance between the combustible wall, etc. and the heating equipment can be ensured, and the combustible wall, etc. can be scorched and ignited. It is extremely safe as there is no need to worry about it.

This produces the same effect as increasing the distance between the heat generating part and the wall by increasing the size of the main body case, so if the restrictor according to the present invention is used, there is no need to intentionally enlarge the main body case. This results in a significant cost reduction. Furthermore, when storing the product during the off-season, the regulating device can be folded by sliding or rotating to make it compact. Furthermore, since the control device and the operating section are linked, heat cannot be generated unless the control device is set in a predetermined protruding position, and while the device is generating heat, the device approaches a combustible wall, etc. within a safe distance. When this happens, the restrictor moves and stops the heat generation, which has the advantage of further improving safety.
