Description

  The present invention relates to a chimney for a heating device attached to the heating device.

  Conventionally, as disclosed in Patent Document 1, an endothermic chimney that uses a blower to heat up the residual heat of the chimney is known by using a blower for a chimney that is attached to a heating device that uses soot, gas, oil, or the like as fuel. It has been. This endothermic chimney has a chimney guard cover that has been distorted to fit an existing chimney, and a siroco fan (an air fan used in a wall-mounted cooler) is installed as a blower, which is attached to the chimney. Let Then, this device is utilized in a place before the heat generated by the combustion of the fuel is exhausted to the outside simultaneously with the exhaust gas, and the heating effect is increased by removing the residual heat of the chimney.

However, the conventional endothermic chimney needs to secure a power source because the power of the white fan that fans up the residual heat of the chimney is electric. Moreover, since the said air blower itself will enlarge in response to the thing with a large size of a heating apparatus or a chimney, it cannot be avoided that it becomes expensive. Furthermore, there is a drawback that noise is generated by rotation of a white fan during driving or driving of a motor.
JP 2002-39629 A

  An object of the present invention is to provide a chimney for a heating device that improves the effect of absorption and heat dissipation of the chimney and the heat inside the chimney without using a blower or the like, thereby increasing the heating efficiency of the heating device.

Means for solving the problems and effects of the device

The present invention is a heating device chimney having a cylindrical chimney that is attached in communication with the heating device and exhausts smoke from an opening provided at a predetermined position.
A plurality of pipe chimneys are provided in parallel with each other at predetermined intervals along the longitudinal direction of the inner surface of the chimney, and are provided so as to protrude inwardly to absorb heat inside the chimney with the chimney. Endothermic fins,
A plurality of cylinder chimneys are provided at predetermined intervals in parallel along the longitudinal direction of the outer surface of the cylindrical chimney, and each is provided so as to protrude outward, and the heat of the cylindrical chimney is radiated to the outside together with the cylindrical chimney. Radiating fins,
It is characterized by providing.

  In this way, the surface area of the chimney is as much as the heat absorption fins and the heat radiation fins provided on the inner and outer surfaces of the chimney compared to a conventional cylindrical chimney without fins (hereinafter referred to as a chimney). Expanding. As a result, it is possible to promote the effect that heat inside the chimney generated by combustion and heat from the heating device are transmitted to the chimney (heat transfer), that is, the effect of heat absorption in the chimney. Moreover, the effect of so-called heat radiation to the outside, which radiates the absorbed heat, can be promoted. In addition, if the effect of heat absorption / radiation is improved, heating efficiency is improved, and accordingly, fuel consumption is reduced and the life of the heating device is extended.

  Also, the inside of the chimney tends to adhere impurities (smoke, tar, etc.) contained in the smoke generated by combustion, and they accumulate, narrowing the flue, or igniting because the entire chimney becomes hot, and the flue There is a risk of fire. Therefore, it is necessary to regularly clean the chimney to maintain a good state with few impurities. Therefore, cleaning is difficult if fins are provided in parallel along the circumferential direction of the chimney inner and outer surfaces, but cleaning is performed by providing them in parallel along the longitudinal direction of the chimney inner and outer surfaces as in the present invention. And the above danger is avoided.

  In the present invention, the heat-absorbing fins and the heat-dissipating fins are provided over the entire circumference of the cross-section of the cylindrical chimney at predetermined intervals alternately.

  In this case, when the heat-absorbing fins and the heat-radiating fins are provided only at predetermined positions, for example, compared to the case where the heat-absorbing fins and the heat-radiating fins are provided only on the half circumference of the chimney cross section, they are provided over the entire circumference of the chimney cross section. Thus, the effect of heat absorption and heat dissipation in the chimney can be improved.

  Moreover, this invention is comprised from the several chimney piece divided | segmented and formed in the circumferential direction by setting at least one of a heat absorption fin and a heat radiation fin as a separation position, and the heat absorption fin or heat radiation fin used as a separation position connects each chimney piece. The connection part for forming is formed.

  In this way, in terms of metal formation, it is easier than forming a cylindrical shape by drawing or the like, and there is no waste because the connecting portion becomes a heat absorbing fin or a heat radiating fin at the time of connection.

In the present invention, the heat absorption fin and the heat radiation fin of the chimney piece are formed by bending a plate member along a fold line parallel to the longitudinal direction,
The connecting part formed at both ends in the circumferential direction of the chimney piece is a male fin part projecting inwardly or outwardly at one end side, and a female type that accepts and consolidates the male fin part at the other end side. A fin portion,
It is assembled by inserting the male fin part of any chimney piece into the female fin part of another adjacent chimney piece.

  Further, according to the present invention, the female fin portion forms a direction changing portion that is bent in the protruding direction of the male fin portion and then returns to the original direction.

  If it does in this way, while being able to improve the integrity of the chimney pieces at the time of connection, positioning with respect to the peripheral direction is made. In addition, since the chimney piece is formed by bending a plate-like member, it is easier to form the chimney piece than in a drawing process or the like.

  In the present invention, the male fin portion and the female fin portion are connected and integrated by fixing means such as welding after the male fin portion is inserted into the female fin portion.

  Thereby, a male fin part and a female fin part can maintain a connected state.

  The heat absorbing fins and the heat radiating fins are provided over the entire circumference of the cross section of the cylindrical chimney in a form protruding inward and outward from a common position in the circumferential direction.

  In this way, the same effect as when the fins are alternately provided at predetermined intervals can be obtained, and in the cross section of the chimney, the fin protrudes inward and outward from a common position in the circumferential direction. The fins can be easily formed in the manufacturing process, and as a result, the manufacturing cost can be reduced.

  Embodiments of the present invention will be described below with reference to the drawings.

Example 1
FIG. 1 shows a state in which a chimney 1 for a heating device according to the present invention is attached to a heating device 2. The chimney 1 for a heating device is attached in communication with a heating device 2 such as a wood stove, and has an opening portion. 3 has a main body portion 4 of a cylindrical chimney for exhausting smoke from 3.

  FIG. 2 is a perspective view showing an embodiment of the chimney 1 for the heating device of FIG. 1, and FIG. 3 is a plan view of FIG. The heating device chimney 1 includes a cylindrical main body 4, heat-absorbing fins 5, and heat-radiating fins 6. Specifically, eight endothermic fins 5 are provided in parallel to the cylindrical main body 4 along the longitudinal direction of the inner surface of the main body 4 at equal intervals of 45 degrees, The tip protrudes inward of the main body 4. The eight heat dissipating fins 6 are provided in parallel along the longitudinal direction of the outer surface of the main body portion 4 at intervals of 45 degrees, and the tips protrude outward in the main body portion 4. Moreover, as for the heat absorption fin 5 and the heat radiation fin 6, each fin is provided alternately.

  As described above, eight heat-absorbing fins 5 and eight heat-radiating fins 6 are provided on the inner and outer surfaces of the main body 4. Thereby, the heat | fever inside the main body 4 which generate | occur | produced by combustion, and the heat | fever stored in the main body 4 itself can be absorbed and thermally radiated by the main-body part 4 and both fins. In short, the surface area of the inner and outer surfaces of the main body portion 4 is increased by the amount of the fins provided, compared to the chimney of the same size without the conventional fins. As a result, the effect of heat absorption / dissipation is promoted, and the heating efficiency can be improved.

  Further, as shown in FIGS. 2 and 3, in this embodiment, the length and thickness of each fin are the same. However, it is not necessary to make the dimensions the same. For example, it is possible to lengthen the heat-radiating fins 6 and shorten the heat-absorbing fins 5. In this way, the effect of heat absorption and heat dissipation can be improved without hindering smoke emission by the short heat absorption fins. Moreover, although both the fins are comprised by 8 pieces, you may be comprised by the number of more or less than that. For example, both the fins can be composed of 10 or 6 fins. When both fins are increased, as described above, the surface area of the chimney 1 for the heating device is also increased, and the effects of heat absorption and heat dissipation are improved. However, if both the fins comprised are reduced, the surface area of the chimney 1 for heating devices will also reduce, and the effect of heat absorption / radiation will fall. In that case, the decrease in surface area can be compensated by adjusting the length and thickness of both fins.

  The heating device chimney 1 according to the present invention is manufactured by, for example, a metal forming drawing process. Generally, the heating device chimney 1, the heat absorbing fins 5, and the heat radiating fins 6 are made of, for example, a steel plate having high heat resistance. Used. In addition, stainless steel or the like may be used, and an appropriate material is selected depending on the usage environment and cost of the heating device. Further, when each fin is formed separately from the main body portion 4 and the fins are attached by welding or the like, the same material may be used for the main body portion 4, the heat absorbing fin 5, and the heat radiating fin 6. However, other materials may be used.

Moreover, it has the heat absorption fin 5 similarly to FIG. 1 thru | or FIG.

  And as shown in FIG. 5, the chimney 1 for heating devices is comprised by uniting the two chimney pieces 7 formed by division | segmentation. Specifically, the divided radiating fins 6a and 6b are respectively connected by means such as screwing or welding, and the chimney pieces 7 are combined. In this way, it is only necessary to form an arbitrary number of the same chimney pieces 7 and combine them, so that the metal is formed rather than forming the chimney 1 for a heating device in a cylindrical shape as shown in FIG. It is easy in terms of

  Moreover, although the example comprised from two chimney pieces 7 was shown in FIG.4 and FIG.5, it is not limited to two, For example, you may divide | segment and form into four or eight. Similarly, in this case, the radiating fins 6 serving as the separation positions respectively form the divided radiating fins 6a and 6b, and by connecting them, the chimney piece 7 is united, and the chimney for a heating device as shown in FIG. 1 is configured. In addition, it is also possible to make the heat absorption fin 5 into a separation position.

  FIG. 6 shows another example of positions where both fins are provided in the chimney 1 for a heating device shown in FIG. The heat absorbing fins 5 and the heat radiating fins 6 are provided over the entire circumference of the cross section of the main body 4 in a form that protrudes inward and outward from a common position in the circumferential direction in the cross section of the main body 4. Specifically, eight heat-absorbing fins 5 are provided in the inner direction and eight heat-radiating fins 6 are provided in the outer direction at an angle of 45 degrees in the circumferential direction. In this way, the same heat absorption / radiation effect as in the example shown in FIG. 3 can be obtained, and both fins are formed at the same position in the cross section of the main body 4. 3 and the example shown in FIG.

  FIG. 7 shows an example of division formation in which the chimney 1 for the heating device of FIG. 6 is composed of two chimney pieces 7. Similarly to the examples shown in FIGS. 4 and 5, the heat absorbing fins 5 and the heat radiating fins are shown. 6, and the divided heat radiation fins 6 a and 6 b are formed as connecting portions for connecting the chimney pieces 7. Further, divided endothermic fins 5a and 5b are formed. The divided heat-absorbing fins 5a and 5b and the divided heat-radiating fins 6a and 6b are connected by means such as screwing and welding, and the chimney pieces 7 are combined.

  Hereinafter, another embodiment of the present invention will be described with reference to the drawings.

(Example 2)
8 is a perspective view showing a folded chimney piece 17 as a chimney piece, FIG. 9 is a plan view showing a state in which two folded chimney pieces 17 are combined, and FIG. 10 is a heating device constituted by the folded chimney piece 17. 1 is a plan view of a chimney 1 for use. In this embodiment, the heating device chimney 1 is divided and formed by eight bent chimney pieces 17.

  As shown in FIG. 8, the bent chimney piece 17 is a first heat-absorbing fin (male type) formed by bending a single plate-like member, such as a steel plate, by a pressing process or the like along a fold line parallel to the longitudinal direction. (Fin part) 15a, the 2nd heat absorption fin (female-type fin part) 15b, and the bending radiation fin 16 are each provided. Specifically, on the left end side in the circumferential direction of the bent chimney piece 17, the first endothermic fin (male fin) is bent so that the left end of the bent chimney piece 17 is bent inward along a fold line parallel to the longitudinal direction. Part) 15a is formed. Then, on the right end side in the circumferential direction of the folded chimney piece 17, first, the right end of the folded chimney piece 17 is bent inward along a fold line parallel to the longitudinal direction, and then is bent at a right angle toward the right end direction to form the linear portion 24. To do. Furthermore, the direction change part 22 is formed by turning at a right angle so that the direction is changed to be parallel to the straight part 24, and the second heat absorbing fin (female fin part) 15b is formed. By forming the second heat absorbing fin (female fin portion) 15b, an insertion portion 23 for receiving and integrating the first heat absorbing fin (male fin portion) 15a is formed. Further, the bent heat radiating fins 16 are formed by bending outward at a right angle with the intermediate position of the bent chimney piece 17 as a base point, and then changing the direction to form the outer surface direction changing portion 20 and being bent back. The At this time, the bent heat radiating fin hollow portion 21 is formed in the inward direction of the bent heat radiating fin 16, and the effect of increasing the surface area can be obtained.

  And as shown in FIG. 9, the 1st heat absorption fin (male type fin part) 15a of the bending chimney piece 17 is formed by the 2nd heat absorption fin (female type fin part) 15b of another bending chimney piece 17. By inserting into the inserted insertion portion 23, positioning in the circumferential direction is performed, and the bent chimney pieces 17 are connected to each other. The other parts are the same as those in FIG.

  Furthermore, as shown in FIG. 10, the eight bent chimney pieces 17 are combined as described above, and the spot welded portion 25 is fixed by spot welding or the like (or may be screwed, riveted, etc.) as a fixing means for each other.

However, in this example, since the chimney piece 17 and each fin are formed by bending a single plate-like member (for example, a steel plate), the first heat-absorbing fin (male fin portion) 15a is thickened. It is possible to make it thinner. Therefore, the bent heat absorbing fins 15 and the bent heat radiating fins 16 do not have to be formed with the same thickness, and two or more bent heat radiating fins 16 may be formed on the bent chimney piece 17. Further, in this embodiment, the first heat absorbing fin (male fin portion) 15a and the second heat absorbing fin (female fin portion) 15b are formed by using the bent heat absorbing fin 15 as a connecting portion. Similarly, you may form a male type fin part and a female type fin part as a connection part.
