Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a heat control device for an oil burning appliance that has good operability and can easily perform delicate heat control.

<Prior Art> In recent years, for the purpose of finely adjusting the heat power and improving the operability, the fuel core is moved up and down by one pitch of the rack teeth using a rack and an engaging element to adjust the heat power. Is provided.

<Problems to be solved by the invention> By the way, in this conventional device, the rotating body is rotated by one pitch of the teeth of the rack by the movement of the engaging element on the rack, and the rotating shaft is simultaneously rotated by this rotation. By moving the fuel core, the fuel core can be moved up and down to be finely adjusted. However, since the weight of the fuel core is always acting on the rotating shaft, the fuel core 1 is engaged by the meshing of the rack and the engaging element. Even if it is attempted to move by pitch, the own weight of the fuel wick acts on the rotary shaft, and in the adjustment in the wicking direction, the rack does not move forward one pitch by one pitch movement, that is, the rack does not advance, and fine adjustment becomes impossible, In addition, in the adjustment in the core lowering direction, if the meshing of the rack and the engaging element is released, the rack will automatically descend, and in any case it will not be possible to make a reliable adjustment and cause malfunction. It was

<Means for Solving Problems> In order to solve the above-mentioned drawbacks by focusing on this point, the present invention has a structure, in particular, a fuel core 5 vertically movable in the core guide tube 1 at one end. A rotary body 6 having a rotary shaft 7 fixed thereto and a rack portion 13 at the other end, and the rotary body 6 meshes with the rack portion 13 to rotate the rotary body 6 by one pitch. In the case of adjusting the heat power by moving it up and down by the engaging elements 32 and 43, the rotating shaft 7 is provided with a balancing means 49 which does not always apply the own weight of the fuel wick 5.

<Action> Button 21 for lowering the core and button 3 for raising the core are used to adjust the heating power.
4 is lightly pressed so that the core lowering button 21 is pressed once when the core is lowered, so that the engaging element 32 moves the core lowering rack 11
The rotating body 6 meshed with the tooth portion 9 of the core lowering rack 11 and the rack 11 fixed thereto is rotated by one pitch in the core lowering direction.
Will also be moved down by one pitch, and at this time, the balancing means 49 consisting of a spring always acts on the rotary shaft 7,
Since the pulling force of the rotary shaft 7 in the core lowering direction is made equal to the own weight of the fuel core 5 so that the own weight of the fuel core 5 is not substantially applied to the rotary shaft 7, the core lowering action is performed smoothly and the subtle heat power is generated. Adjustment is performed, and conversely, when the centering-up button 34 is pressed, the engaging element 43 causes the centering-up rack 12 to move.
The rack 12 and the rotating body 6 are rotated one pitch at a time by engaging with the tooth portion 10 of the above, and the fuel core 5 is moved upward to adjust in the direction of the large heating power. Since the acting force of the balancing means 49 is applied to the shaft 7, the weight of the fuel wick 5 is not applied to the rotating shaft 7, and the rack 12 advanced by one pitch is returned again as in the conventional case, and the top of the fuel wick 5 is returned. There are no problems such as inability to move, and it is possible to control the firepower reliably.

Reference numeral 49 is a balancing means composed of a spring for constantly pulling the rotary shaft 7 in the center-up direction, and its tension or moment is always balanced with the own weight of the fuel core 5 so that the own weight of the fuel core 5 does not act on the rotary shaft 7. . Reference numeral 50 is an insertion port into which a fuel supply port of a fuel supply tank (not shown) is inserted to supply fuel oil to the fuel oil tank 3. Next, the operation of this embodiment will be described.

First, the ignition operation will be described. If the tip end of the ignition lever 14 is held down and pushed down, the tip end of the thermal power adjustment lever part 8 is also pushed down via the pressing part 15, whereby the rotary shaft 7 is rotated. Is rotated in the counterclockwise direction to operate the wick up-down device to move the fuel wick 5 upward to perform the wicking operation, and the rotation of the fire power adjusting lever portion 8 causes the rotator 6 integrated with the wick 5. Also rotates to move the racks 11 and 12 at the upper end to positions facing the engaging elements 32 and 43, and when both levers 8 and 14 reach the lowermost position, the fuel core 5 Is at the highest position and the ignition device 17 is operated by the push-up portion 19 of the ignition lever 14 to bring the ignition heater 18 close to the elevated fuel wick 5 to complete the ignition.
By further releasing the hand, the ignition lever 14 moves to the spring 2
With the restoring force of 0, the original state is restored, and combustion is continued.

Next, when adjusting the heat power from this state, the operation plate 2
2 The center lowering button 21 and the center raising button 34 protruding to the front are operated, but since the fuel core 5 is at the highest position now, the center raising rack 12 is disengaged from the engaging element 43. Therefore, in this state, only the core lowering button 21 can be operated, and when the core lowering button 21 is pressed there, the core lowering button 21 rotates about the shaft 23 as a fulcrum and moves to the lower end. The actuator 26 with the spring 2
By pushing against 5 and moving inward, the cam groove 27
The engaging element 32, which is inserted into and connected to the shaft 28, first moves downward in the cam groove 27 by the cam, so that the engaging member 32 is rotated by the acting force of the spring 31 and the claw 33 at the tip is moved to the core. If it engages with one of the tooth portions 9 of the lowering rack 11, and further presses the core lowering button 21 in this state,
Since the support shaft 30 slides in the sliding groove 29 and the entire engaging element 32 moves inward, the rotating body 6 in which the engaging element 32 meshes guides the upper rack portion 13 to the guide portion 45. Therefore, the core 11 is rotated by one pitch and the rotary shaft 7 is also rotated clockwise to move the fuel core 5 downward by one pitch. When the press button 21 is pressed, the above operation is repeated again and the fuel core 5 is moved by another pitch of the tooth portion 9 of the core lowering rack 11.
To gradually lower the wick 5 to adjust the heat power to the small heat power side, and at this time, the rotary shaft 7
Since the weight of the fuel wick 5 does not act on the rack 11 due to the action of the balancing means 49, there is no problem that the rack 11 lowers several pitches at a time due to the weight of the fuel wick 5, and the rack 11 can be moved one pitch at a time. This allows good control of firepower.

Further, the downward movement of the fuel core 5 by the core lowering button 21 is designed to prevent the fuel core 5 from descending to the fire extinguishing position within the range of the projected size of 2 mm and the heat generation amount of 50%.

Next, after adjusting the fuel core 5 to the small heat side, when moving the fuel core 5 up this time to adjust to the large heat side, the core raising button 34 is pressed to press the core. The raising button 34 rotates about a shaft 35 as a fulcrum, so that the movable body 39 connected to the center raising button 34 via a connecting rod 40 rotates about a support shaft 37 as a fulcrum against the acting force of the spring 38. Then, the claws 44 of the engaging element 43 provided at the tip end thereof are engaged with the tooth portions 10 of the centering rack 12 facing each other, and the centering button 34 is further pressed in this state, whereby the engaging element 4
3 rotates upward with the shaft 41 as a fulcrum against the acting force of the spring 42. Therefore, the rotary body 6 in which the engaging element 43 meshes rotates by one pitch of the centering rack 12 and As a result, the rotary shaft 7 also rotates in the counterclockwise direction to move the fuel wick 5 upward by one pitch, and if the wick-up button 34 is pressed again, the above operation is repeated and the wick is repeated. The fuel core 5 is moved up by another pitch of the tooth portion 10 of the lifting rack 12, and the fuel core 5 is sequentially moved up little by little to adjust the heating power to the large heating power side. Since the balance means 49 acts on the rotating shaft 7, the rack 12 moved by one pitch does not return due to the weight of the fuel wick 5 and the heating power cannot be adjusted in the upward direction, and the heating power is always smooth. It can be adjusted, and the operation is light and easy. Than it is.

<Effect of the Invention> In short, according to the present invention, the fuel wick 5 vertically movably provided in the wick guide cylinder 1, the rotating body 6 having the rotating shaft 7 fixed to one end and the rack portion 13 at the other end is provided. And the engaging elements 32 and 43 that mesh with the rack portion 13 of the rotating body 6 and rotate the rotating body 6 by one pitch of the rack portion 13 to adjust the heating power. Since the rotating shaft 7 is provided with the balancing means 49 that does not always act on the own weight of the fuel core 5, delicate heat power adjustment is extremely easy and reliable, and the own weight of the fuel core rotates as in the conventional case. It is certainly prevented that the heat power cannot be adjusted due to being applied to the shaft, and accurate operation can always be performed, and the operation is light and the operability is extremely good, and its practical value is great. .
