  The present invention relates to an air-cooling device and an air-cooling method, and more particularly to an air-cooling device and an air-cooling method for air-cooling a plurality of parts to be cooled arranged along a ventilation direction.

  Generally used gas stoves and IH grills are provided with means for taking in outside air such as fans and openings in order to prevent abnormal temperature rise in the gas stove and grill chambers. A structure that cools the entire interior is adopted. In addition, since this conventional structure is generally well known, patent documents are not particularly shown.

  However, in such a conventional structure, for example, even in the case where a plurality of parts to be cooled that are particularly required to be cooled are arranged along the ventilation direction of the outside air, the inside of the chamber in which the parts to be cooled are arranged is reduced. In particular, it is not cooled sufficiently due to the influence of heat when the part to be cooled arranged on the side far from the ventilation means such as a fan is cooled. There was a problem.

  In recent years, IH inverter heaters have become widespread, but similar problems have also arisen in IH inverter heaters. Furthermore, in such IH equipment, especially from IH pans heated by heating coils, etc. Heat is transferred to the inside of the chamber near the heating coil via the coil base. As a result, the temperature in the chamber becomes high, affecting the current adjustment of the heating coil, or the heating operation is automatically performed by the function of the safety device. There was a problem of being stopped. In addition, the IH inverter heater has a problem that cooling is likely to be insufficient because the distance between heating coils that require cooling cannot be secured because of the inverter characteristics.

Concentration means for concentrating on the cooled part may also be provided.

  According to another aspect of the present invention, air is passed through a plurality of sections in the partitioned chamber in a predetermined direction, and a plurality of parts to be cooled among the plurality of sections are in the predetermined direction. The portion to be cooled is cooled by the air ventilated in at least one section disposed along the portion to be cooled, the portion to be cooled disposed on the side close to the ventilation means, and the plurality of portions to be cooled The at least one section and the at least one section are between a portion to be cooled and a portion to be cooled disposed on the side closer to the ventilation means and a portion to be cooled disposed on the side far from the ventilation means.

It may be possible to prevent a wind blown into a section different from the at least one section blowing out from the air from colliding.

  In addition, the said air cooling apparatus and the air cooling method are applicable to an IH inverter heater, for example.

  Hereinafter, an air cooling device according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings. In addition, although the air cooling apparatus and the air cooling method of this invention can be applied to various apparatuses, the application example to an IH inverter heater is demonstrated as a suitable example here.

  1 is a central cross-sectional view of an air cooling device according to the present invention applied to an IH inverter heater, FIG. 2 is a front cross-sectional view along the AA line of FIG. 1, and FIG. 3 is a top view of the air cooling device of FIG. FIG. 4 is a partially broken perspective view of the air cooling apparatus of FIG. For convenience, FIGS. 3 and 4 show a state in which the upper part is removed from the IH inverter heater.

  The IH inverter heater 10 includes, as its basic configuration, a main body 11, a partition plate 24 that partitions the upper interior of the main body 11, a glass plate 26 that covers the upper portion of the main body 11, and a temperature sensor attached to the bottom side of the glass plate 26. (Not shown) etc., the component storage unit 25, the cooling fan 28 for taking outside air into the chamber 40 and ventilating it, and the current for heating the heating target such as an IH pan (not shown). A heating coil 22 to be generated and a coil base that substantially divides the chamber 40 into two upper and lower sections along the direction of ventilation, that is, an upper section 33 and a different lower section 34 and supports the heating coil 22 20, an IH inverter heater unit 30 for controlling the current applied to the heating coil 22, and preferably an IH inverter To dissipate the heat generated from the heat unit 30 includes a dedicated unit cooling fan 32. The coil base 20 is provided with a plurality of substantially fan-shaped holes 45 along the winding direction of the heating coil 22, and these holes 45 are substantially closed by the heating coil 22. You can think about it.

  The partition plate 24 includes a front plate 42, a bottom plate 44, and left and right side plates 46, and an upper portion thereof is covered with a glass plate 26. The chamber 40 is substantially formed by the partition plate 24 and the glass plate 26. One side surface of the rear side 49 of the chamber 40 is open inside the main body 11. A hole 47 that connects the main body 11 and the chamber 40 is provided in front of the bottom plate 44 (of the chamber 40) of the partition plate 24 that is a part of the chamber 40, and outside air is supplied to the chamber 40 through the hole 47 by the cooling fan 28. It is supposed to be taken in. Here, in order to increase the cooling capacity, two cooling fans 28 are arranged on the left and right (in the direction orthogonal to the ventilation direction). However, the number and arrangement method of the cooling fans 28 are not particularly limited, and it is sufficient that sufficient ventilation can be performed in the chamber 40. For example, the number of cooling fans is one or more than three, or two cooling fans are arranged in the front and rear direction (ventilation direction), and one cooling fan is mainly used to ventilate the upper section 33. The other cooling fan may be used mainly for ventilating the lower section 34. The outside air taken in by these cooling fans 28 is used to cool the inside of the chamber 40 and the heated heating coil 22, and then is discharged from an open portion on the rear side 49 of the chamber 40. Thus, in the chamber 40, the cooling air is substantially ventilated in a direction from the front to the rear of the chamber 40.

  It is particularly in the vicinity of the heating coil 22 </ b> A and the vicinity of the heating coil 22 </ b> B disposed in the upper section 33 that cooling is required by the air in the ventilated chamber 40. The heating coils 22A and 22B that have generated heat are of course subject to cooling, and of course, the heating coils 22A and the heating coils 22A that have been raised by transferring heat from the IH pan heated by the heating coils 22A and 22B through the coil base 20; The internal air in the chamber 40 in the vicinity of 22B can also be a cooling target. It should be noted that the vicinity of the heating coil 22A and the vicinity of the heating coil 22B that require cooling are arranged along the ventilation direction (front and rear) inside the chamber 40. This arrangement necessitates effective cooling particularly in the vicinity of the heating coil 22B disposed on the side far from the cooling fan 28.

  The wind generated by the cooling fan 28 is first divided into two upper and lower directions in the ventilation direction, that is, the upper section 33 and the lower section 34 by the action of the diversion baffle 62 existing in the lower section 34. The shunt baffle 62 extends in a straight plate shape in the left-right direction of the chamber 40 and has a cross-section “<” shape, and its tip 63 is near the center of the cooling fan 28, that is, the rotation axis of the cooling fan 28. The rear end 64 is supported and fixed to the upper part of the edge 21 of the coil base 20. The wind diverted to the upper section 33 by the action of the diverting baffle 62 then flows in the direction of arrow A in FIGS. 1 and 4 by the action of the concentrated baffle 65 and the collision prevention baffle 66 described later, and is closer to the cooling fan 28. It is used to cool the internal air in the chamber 40 in the upper part of the heating coil 22A disposed in the vicinity of the heating coil 22A and in the vicinity of the upper part of the heating coil 22A. On the other hand, the wind diverted to the lower section 34 by the action of the diversion baffle 62 is then flowed along the direction of arrow B in FIGS. 1 and 4 by the action of the windproof baffle 71 and the collision prevention baffle 66 described later, and the heating coil In order to cool the lower part of 22A, the upper part of the heating coil 22B disposed on the side far from the cooling fan 28, the internal air in the chamber 40 near the upper part of the heating coil 22B, and the lower part of the heating coil 22B used.

  In particular, the wind diverted to the upper section 33 by the diversion baffle 62 is applied to the heating coil 22A in the upper section 33 by the action of the concentrated baffle 65 disposed closer to the cooling fan 28 than the heating coil 22A in the ventilation direction. Concentrated to cool the internal air in the chamber 40 in the upper part of the heating coil 22A and in the vicinity of the upper part of the heating coil 22A more effectively. As shown in FIG. 3 and FIG. 4, the concentrated baffle 65 is preferably provided in two left and right 65A, 65B, and “C” shapes. These concentrated baffles 65A and 65B are each of a relatively small straight plate shape, extend from the inner side walls 48A and 48B so as to reduce the distance between the tips 75A and 75B in the ventilation direction of the chamber 40, and In addition, the state is inclined toward the heating coil 22A disposed in the vicinity of the center.

  Similar to the concentrated baffle 65, the collision prevention baffle 66 exists in the upper section 33, and is formed into a plate-like body formed in a “<” shape by being bent in the left-right direction at the central bent portion 68. The crest side of the bent portion 68 is arranged in front of the chamber 40, and the trough side of the bent portion 68 is arranged behind the chamber 40. The used wind which is diverted to the upper section 33 by the diverting baffle 62 and used for cooling the upper portion of the heating coil 22A and the like is used in two directions (left and right in FIG. 4) using the mountain side portion of the anti-collision baffle 66. The gap 76A formed between the end portions 67A and 67B of the collision prevention baffle 66 installed in the chamber 40 and the inner walls 48A and 48B after colliding with the inner walls 48A and 48B after being shunted to the arrows A1 and A2). It is guided along the inner side walls 48A, 48B through 76B and discharged from the rear side 49. By providing such an anti-collision baffle 66, it is possible to prevent the relatively high-temperature used wind used for cooling the heating coil 22A from being sent directly to the heating coil 22B. It is possible to prevent the cooling of the battery from being adversely affected. The anti-collision baffle 66 may be a flat plate (not shown) extending in the left-right direction without being folded into a “<” shape as described above, but is folded into a “<” shape. Thereby, the flow of air can be made smoother.

  On the other hand, the wind diverted to the lower section 34 by the diversion baffle 62 passes under the heating coil 22A along the direction of arrow B in FIGS. 1 and 4 and is heated through the hole 45 (see FIG. 3). After the lower part of the coil 22A is cooled, the direction is changed upward by the action of the windproof baffle 71. The windproof baffle 71 exists in the lower section 34 and is arranged in a straight plate shape in the left-right direction of the chamber 40 in a state of being inclined upward along the ventilation direction, and its tip 73 is formed on the inner wall of the bottom plate 44 of the chamber 40. The rear end 74 is supported and fixed to the lower portion of the edge 23 on the rear side of the hole 69 on the side far from the cooling fan 28 in the ventilation direction. The windproof baffle 71 substantially partitions between the heating coil 22 </ b> A disposed on the side close to the cooling fan 28 and the heating coil 22 </ b> B disposed on the side far from the cooling fan 28 in the lower section 34. By providing such a windproof baffle 71, especially in the lower section 34, the air that has passed through the lower section 34 is disposed on the side farther from the cooling fan 28 than the heating coil 22 </ b> A disposed on the side closer to the cooling fan 28. Ventilation to the heating coil 22B is substantially prevented. However, by providing a plurality of holes 72 in the windproof baffle 71, a part of the wind diverted to the lower section 34 is caused to flow below the heating coil 22B, and the lower part of the heating coil 22B is passed through the hole 45 (see FIG. 3). Can also be cooled.

  The wind whose direction has been changed upward by the action of the windproof baffle 71 is then moved between the heating coil 22A and the heating coil 22B, more specifically, at the internal position of the "<" of the collision prevention baffle 66. It blows out to the upper section 33 through the triangular hole 69 provided in the base 20 for connecting the upper section 33 and the lower section 34. The blown-out air can cool the upper part of the heating coil 22B disposed on the side far from the cooling fan 28 and the internal air in the chamber 40 near the upper part of the heating coil 22B. Since the collision prevention baffle 66 is provided on the side closer to the cooling fan 28 than the hole 69, the air blown from the hole 69 to the upper section 33 (the wind indicated by the arrow B in FIG. 4) and the upper section from the beginning. The wind that has been ventilated to 33 (the wind of the arrow A in FIG. 4) does not mix. Further, since the hole 69 is disposed at a substantially central position of the heating coil 22B, the wind obtained through the hole 69 is to efficiently cool the heating coil 22B near the center thereof. It does not collide with the wind guided backward through the gaps 76A and 76B.

  Although the example which provided the two divisions 33 and 34 up and down was demonstrated, of course, you may provide three or more divisions. If the number of parts to be cooled (in the above example, the vicinity of the heating coils 22A and 22B) increases, the number of sections can be increased and any part can be efficiently cooled by the same method as above.

  It can be applied to various devices that require air cooling.
