Description

  The present invention relates to an induction heating cooker having an induction heating coil for heating a cooking pan or the like.

  In the conventional induction heating cooker, the main heating means is an induction heating coil, and the eddy current is generated in the cooking pan placed on the top plate made of heat-resistant glass by the magnetic flux generated thereby, and the cooking pan is heated. Is. This induction heating cooker has less heat radiation to a portion other than the cooking pan and has good thermal efficiency as compared with a cooker such as gas.

  A top plate on which the cooking pan is placed is provided on the upper surface of the main body. Below this top plate, an induction heating coil is disposed on the upper left and right of the main body, and a heating source such as an induction heating coil and a resistance heater is disposed in the central portion on the rear side. A structure in which a control board such as an output board and a grill part for cooking in a cooking chamber are provided on the lower left and right of these heating sources is generally used.

  Since the induction heating cooker having such a configuration generates heat not only from the pan but also from the induction heating coil and the control board when the cooking pan is heated, air cooling is performed using a cooling fan.

  As an example of the air cooling, there are those described in Patent Document 1 and Patent Document 2, for example.

JP 2003-77637 A JP 2003-86339 A

  The one shown in Patent Document 1 has an intake port on one side of the upper rear of the main body, an exhaust port on the other side, and a blower fan at the rear of the main body below the intake port. Between the blower outlet of the blower fan and the induction heating coil disposed on the upper left and right sides of the main body, a dedicated air passage that is inclined upward is provided on the coil side, and is directed obliquely upward from the blower fan to the induction heating coil through the dedicated air passage. Air is blown to cool the induction heating coil.

  Further, the one shown in Patent Document 2 is not provided with the dedicated air passage shown in Patent Document 1, and is cooled on the upper surface of the storage case containing the control board so as to face the induction heating coils arranged on the upper left and right sides in the main body. After opening the air outlet and cooling the control board by blowing cool air from the blower fan into the storage case, the air is blown from the cooling air outlet to the lower surface of the induction heating coil to cool the induction heating coil. is there.

  In these conventional cooling structures, the one shown in Patent Document 1 is due to a structural limitation that a control board, a roaster section, a plurality of induction heating coils, etc. must be accommodated in a limited space in the main body. In addition, it is not possible to make a structure in which air is blown perpendicularly to the whole induction heating coil from directly under the induction heating coil. Instead, as described above, a dedicated air passage is provided between the blower outlet of the blower fan and the induction heating coil, and the induction heating coil is blown from the blower fan through the dedicated air passage to cool the induction heating coil. Yes.

  However, with this structure, the cooling air cannot be uniformly applied to the entire surface of the induction heating coil, and the cooling air is concentrated on a part of the induction heating coil, that is, the farthest part where the cooling air ends.

  For this reason, a temperature difference becomes large with the difference of the cooling effect of the site | part which does not hit with cooling air, and the site | part which hits, ie, the site | part of an induction heating coil. Therefore, in order to suppress the temperature rise in the portion where the cooling air of the induction heating coil is not directly applied, there is a problem that a larger amount of air is required.

  In addition, even if a dedicated air path is provided from the induction heating coil on the side closer to the blower fan to the induction heating coil on the far side, the induction heating on the far side after passing through the induction heating coil on the side closer to the blower fan. Since it reaches the coil, the temperature of the cooling air rises in the meantime, and the rear part of the far-side induction heating coil cannot be sufficiently cooled, and the temperature difference increases depending on each part of the induction heating coil. In order to eliminate this temperature difference, there was the same problem as described above that a larger amount of air flow was required.

  Further, in the cooling structure that blows the induction heating coil obliquely upward to the induction heating coil shown in Patent Document 1, since the air is not blown in the vertical direction with respect to the portion that requires cooling of the induction heating coil, a sufficient cooling effect can be obtained. There was also a problem of not being.

  Moreover, what is shown in Patent Document 2 is that only the cooling air jet opening is opened on the upper surface of the storage case storing the control board so as to face the induction heating coils arranged on the upper left and right sides in the main body. The cooling air blown from the cooling air outlet is diffused to the periphery of the cooling air outlet, and the induction heating coil cannot be efficiently cooled.

  Moreover, since the thing shown to patent document 2 is not blowing in the orthogonal | vertical direction with respect to the cooling-required surface of an induction heating coil like patent document 1, there existed a subject that sufficient cooling effect was not acquired.

  An object of the present invention is to solve at least one of the above-described problems and increase the cooling efficiency of the induction heating coil in the induction heating cooker.

In order to solve the above conventional problems, an induction heating cooker according to claim 1 of the present invention includes a top plate provided on the upper surface of the main body, and an induction heating coil disposed in the main body below the top plate. A board case including an electronic control board provided in the main body for controlling the drive of the induction heating coil, a blower fan for cooling the heating coil and the electronic control board, and the induction heating coil from the blower fan. A cooling air passage for guiding the cooling air; a cooling air blowing inlet provided in the cooling air passage; a blower outlet pipe provided on the opposite side so as to open to the lower surface of the induction heating coil; and the blower outlet pipe internal to have a plurality of baffle plates for guiding the cooling air to the induction heating coil disposed radially outside wall surface of the plurality of baffle plates, the upper surface substantially the same height of the blow outlet tube Have The center side wall of the air guide plate is obtained by reducing the height from the outer wall surface.

  In claim 2, the cooling air passage is provided with a reflection guide cylinder at a position facing the peripheral edge of the induction heating coil before reaching the blower outlet cylinder, and the cooling air blown from the upper opening is applied to the peripheral edge of the induction heating coil. So that it is cooled.

According to a third aspect of the present invention, in the cooling air passage, a plurality of reflectors are arranged at a lower depth in the flow direction of the cooling air so as to block the flow of the cooling air in the blower outlet tube opened on the lower surface of the induction heating coil. Are arranged side by side so that they become deeper in order.

  According to the present invention, the cooling air can be efficiently applied toward the induction heating coil, and the induction heating cooker can be efficiently cooled.

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

  1 to 5 show an embodiment of the induction heating cooker of the present invention. The cooking device shown in FIG. 1 is a built-in induction heating cooking device provided with pan mounting portions 6a, 6b, and 6c at three locations on the top plate 3, as will be described in detail below.

  Note that the present embodiment may be applied to a stationary heating cooker that is placed in the kitchen instead of the built-in type that fits in the kitchen.

  The induction heating cooker is incorporated into the system kitchen 1 by installing the main body 2 by dropping it into the opening of the system kitchen 1 from above. After the installation, the roaster unit 4 and the operation unit panel 5 having a grill function to be described later can be operated from the front part of the system kitchen 1.

  A cooking pan (not shown) for cooking is placed on a top plate 3 made of heat-resistant glass or a metal frame provided on the upper surface of the main body 2.

  The cooking pan can be cooked by being placed on the placing portion 6 drawn on the top plate 3. The placement unit 6 is provided with a placement unit right 6 a and a placement unit left 6 b on the front surface side of the top plate 3. A placement portion center 6c is disposed in the back intermediate portion between the placement portions 6a and 6b.

  In the upper part of the main body 2 corresponding to the pan placement portions 6a, 6b, 6c of the top plate 3, an induction heating coil 13 consisting of an induction heating coil right 13a and an induction heating coil left 13b for heating the cooking pan, resistance Each heater center 13c is installed. The resistance heater center 13c may be an induction heating coil.

  The placement center 6c is a place where it is difficult to reach the user's hand. For this reason, when a cooking pan is placed on the mounting unit right 6a and the mounting unit left 6b in front, if the hand is extended to the mounting unit center 6c, the cooking unit is placed on the mounting unit right 6a and the mounting unit left 6b. It is difficult to perform cooking by moving the hand at the placing portion center 6c due to steam generated during cooking from the cooking pot.

  Accordingly, the type of cooking performed at the placing portion center 6c is suitable for cooking that does not require the chef to move much, mainly cooking such as stew or heat retention.

  In addition, since stew and heat retention require only a small heating power, and there is a limit on the maximum power consumption when using an induction heating cooker, the heating power of the resistance heater center 13c installed in the mounting section center 6c is changed to the mounting section. It is set to be weaker than the induction heating coil right 13a and the induction heating coil left 13b installed corresponding to the right 6a and the placement portion left 6b, and to reduce the power consumption of the resistance heater center 13c.

  In this embodiment, the induction heating coil right 13a and the induction heating coil left 13b are approximately 3 kW, and the resistance heater center 13c installed in the placement portion center 6c is approximately 1.6 kW.

  Although not shown, a voltage of several tens of kHz and several hundreds of volts is applied from the inverter means to the induction heating coil right 13a and the induction heating coil left 13b to heat the cooking pan.

  Moreover, it is not necessary to attach to the four sides of the plate 3, and only the front side of the plate 3, only the rear side, only the two front and rear sides, or only the two left and right sides may be used.

  As shown in FIGS. 2 and 3, the inside of the main body 2 is partitioned into upper and lower two stages by a partition plate 17. On the upper side, an induction heating coil right 13a, an induction heating coil left 13b, and a resistance heater center 13c are provided. On the lower side, there are provided a substrate case 16 containing various electronic control boards (not shown) for controlling these heat generating portions and a cooling fan 15 described later.

  On the right side of the rear upper surface of the main body 2, an air inlet 7 for sucking air from the outside is provided so as to face the blower fan 16. The intake port 7 is also located on the right side of the exhaust port 8 provided on the left side of the rear upper surface of the main body 2.

The blower fan 15 is disposed below the partition plate 17 in the main body 2 and between the air inlet 7 and the rear portion of the substrate case 16.

  The air sucked from the air inlet 7 by the blower fan 15 cools the electronic control board in the board case 16, then flows out to the upper surface side of the partition plate 17, the induction heating coil right 13 a on the upper surface, and cooling described later. After cooling the induction heating coil left 13 b through the air passage 19, it is discharged out of the main body 2 from the exhaust port 8. Further, waste heat of the roaster section 4 described later is also discharged from the exhaust port 8 along with the exhaust.

  In FIG. 1, the roaster portion 4 is for baking fish, pizza, etc., and is disposed on the left or right side of the front surface of the main body 2 (left side in the present embodiment), so that the degree of burnt inside can be seen on the front surface. A roaster door 32 having a handle 11 is provided. Note that the roaster section 4 is not dedicated to grilled fish and may be called a grill or an oven.

Even if the operation panel 5 on the front surface of the main body 2 is not operated, the operation can be easily performed on the upper surface of the main body 2.

  The upper surface display unit 10 is provided on the front side of the top plate 3 along with the upper surface operation unit 9. The thermal power setting, cooking menu, timer value, cooking temperature, etc. set by the upper surface operation unit 9 are displayed in an easy-to-understand manner for the user.

  Next, the details of the cooling air passage 19 for cooling the induction heating coil left 13b will be described with reference to FIGS.

  The cooling air passage 19 is a substantially rectangular tubular passage that communicates the blower fan 15 and the induction heating coil left 13 b on the upper surface of the roaster section 4. One opening of the cooling air passage 19 is a blower inlet 20 through which the cooling air after cooling the electronic control board and the induction heating coil right 13a in the board case 16 by the blower fan 15 flows.

  On the opposite side of the air inlet 20, the cooling air passage 19 is connected to a substantially cylindrical air outlet tube 21 that has a smaller diameter than the induction heating coil left 13b and that opens with an appropriate gap on the lower surface thereof. In the blower outlet cylinder 21, a substantially radial reflecting plate 22 including a right reflecting plate 22a, a left reflecting plate 22b, and a central reflecting plate 22c is provided. Each of the reflection plates 22 is a wind guide plate having a role of changing the direction of the cooling air.

  The right reflecting plate 22 a, the left reflecting plate 22 b, and the central reflecting plate 22 c each have an outer wall surface that is increased outward and a lower wall surface that is lower than the outer wall surface extending to the center of the blower outlet tube 21.

  The right reflection plate 22a and the left reflection plate 22b face the cooling air outflow side of the cooling air passage 19 so as to block the cooling air flowing out into the blower outlet tube 21. Before the wind flowing under the air reaches the substantially central part of the blower outlet cylinder 21, it is caused to collide with the lower side wall surfaces of the right reflector 22a and the left reflector 22b and rise upward.

  The central reflecting plate 22c reaches the far side while dispersing the cooling air after passing through the right reflecting plate 22a and the left reflecting plate 22b to the left and right, and rises upward along the inner wall surface of the blower outlet tube 21. .

  Therefore, the right reflecting plate 22a, the left reflecting plate 22b, and the central reflecting plate 22c have their outer wall surfaces raised so as to be substantially the same as the upper surface of the blower outlet tube 21 to raise almost all of the cooling air upward. In addition, the height of the wall surface (lower wall surface) on the center side is made low so that the cooling air flowing through the upper part reaches the farthest wall surface of the blower outlet cylinder 21 and rises upward. It is said.

  As a result, the cooling air that has flowed into the blower outlet cylinder 21 uniformly strikes the entire surface of the induction heating coil 13b disposed on the upper surface thereof, thereby efficiently cooling the induction heating coil 13b.

  In the cooling air passage 19, a plurality of reflection guide cylinders 23 (two in the drawing) are provided on the upper surface before reaching the air outlet cylinder 21. These reflection guide tubes 23 a and 23 b have a wall 23 d that blocks the cooling air flowing in the cooling air passage 19 at the lower portion and allows the cooling air to flow into the reflection guide tube 23.

  On the other hand, the upper opening of the reflection guide cylinder 23 opens along the peripheral edge of the induction heating coil left 13b before reaching the blower outlet cylinder 21. As a result, cooling air blown from the upper opening of the reflection guide tube 23 is applied to the peripheral edge of the induction heating coil left 13b before reaching the blower outlet tube 21 to be cooled.

  Next, a case where a cooking pan is placed on the placement portion left 6b of the top plate 3 and heated by the induction heating coil left 13b will be described.

  First, after putting a cooking pot on the placement part left 6b of the top plate 3, the power on / off switch of the operation panel 5 is turned ON.

  Next, the heating output of the induction heating coil left 13b is set, and the heating power adjustment, the setting of the cooking timer, and the cooking menu are called by the upper surface operation unit 9 provided on the front side of the top plate 3 according to the contents to be cooked. Settings such as heat insulation, boiled food, automatic rice cooking, fried food cooking, setting of cooking temperature, start of heating, etc. are performed.

  At this time, the heating power setting, cooking menu, timer value, cooking temperature, and the like set by the upper surface operation unit 9 are displayed on the upper surface display unit 10 so as to be easily understood by the user.

  When cooking starts, the user puts seasonings and the like in the cooking pan while watching the progress according to the cooking contents, and finishes the seasoning as desired. Cooking is completed by the above operation.

  Next, the cooling of the induction heating coil left 13b during this operation will be described in detail.

  As shown in FIGS. 2 and 3, when the overheating at the induction heating coil left 13 b is started, the cooling air flows into the main body 2 from the intake port 7 as indicated by the arrow by driving the blower fan 15. The cooling air flowing into the board case 16 from the blower fan 15 cools the control board and then flows out to the upper surface of the board case 16. Then, after the cooling air that has flowed out cools the induction heating coil right 13a that is arranged directly or directly above it, it flows out from the air inlet 20 of the cooling air passage 19 into the cooling air passage 19, and part of it. The cooling air hits the reflection wall 23d of the reflection guide tube 23 before reaching the air outlet tube 21, flows into the reflection guide tube 23, and flows out to the peripheral edge of the induction heating coil left 13b before reaching the air discharge tube 21. The peripheral edge is cooled.

  On the other hand, the cooling air that has flowed into the blower outlet tube 21 hits the lower wall surface and the outer wall surface of the right reflection plate 22a and the left reflection plate 22b on the center side of the right reflection plate 22a and the left reflection plate 22b, and reaches the substantially central portion of the blower outlet tube 21. The wind rising upward and passing the upper side of the right reflector 22a and the left reflector 22b reaches far while being dispersed left and right by the central reflector 22c, and along the inner wall surface of the air outlet cylinder 21 Ascend upward.

  As a result, the cooling air that has flowed into the blower outlet cylinder 21 rises substantially vertically on the entire surface of the induction heating coil 13b disposed on the upper surface thereof, and uniformly strikes the cooling coil 13b.

  That is, the cooling air that has flowed into the blower outlet cylinder 21 is reflected on the respective wall surfaces by the right reflector 22a, the left reflector 22b, and the center reflector 22c, becomes a dispersed flow, rises, and rises to the induction heating coil left 13b. The air is blown to the center and periphery of the slab and cooled.

  In addition, other cooling air that does not hit the right reflector 22a, the left reflector 22b, and the center reflector 22c also rises upward along the inner wall of the blower outlet cylinder 21, and blows to the center and the left side of the left heating device for cooling. To do. As a result, the entire surface of the induction heating coil left 13b is cooled uniformly.

  In the above-described embodiment, the two reflection guide cylinders 23 are provided in the cooling air passage 19, and the right reflection plate 22a, the left reflection plate 22b, the central reflection plate 22c, and the three reflection plates are provided in the blower outlet tube 21. However, these are not limited to two or three, and the entire surface of the induction heating coil left 13b can be accurately cooled by changing the number and position of the arrangement.

  Further, by changing the inner diameter of the reflection guide cylinder 23 and the height of the reflection plate 22, that is, the wall surfaces of the right reflection plate 22a, the left reflection plate 22b, and the central reflection plate 22c, the amount of cooling air and the range of cooling air can be easily distributed. , And the cooling air can be raised uniformly and substantially vertically to uniformly cool the entire surface of the induction heating coil left 13b.

  A second embodiment will be described with reference to FIGS.

  In the same cooling air passage 19 as described above, three reflection guide tubes 23a, 23b, and 23c are provided along the peripheral edge of the induction heating coil left 13b on the upper surface left, center, and right before reaching the air outlet tube 21. It has been. Similar to the first embodiment, these reflection guide cylinders 23 are provided with a reflection wall 23d that blocks cooling air flowing in the cooling air passage 19 and flows into the reflection guide cylinder 23 in the lower part, and the upper opening is formed in the blower outlet cylinder. The induction heating coil is opened at the peripheral edge of the left coil 13 b before reaching 21, and the cooling air blown from the upper surface opening of the blower outlet tube 21 is applied to the peripheral edge for cooling.

  In addition, a plurality of (5 in the figure) along the flow direction of the cooling air in the substantially cylindrical air outlet tube 21 having a smaller diameter than the induction heating coil left 13b and opened on the lower surface thereof so as to block the flow of the cooling air. ) Reflectors 24a to 24e are arranged side by side so that the depth of the lower portion becomes deeper in order.

According to this configuration, as shown in FIG. 7, a part of the cooling air that has flowed into the cooling air passage 19 from the air inlet 20 of the cooling air passage 19 is reflected to the reflection guide cylinder 23 a before reaching the air outlet cylinder 21. 23b,
It hits the reflection wall 23d of 23c and flows almost vertically into the reflection guide tube 23, and flows out to the peripheral portion of the induction heating coil left 13b before reaching the blower outlet tube 21 to cool the peripheral portion.

  On the other hand, most of the cooling air that has flowed into the air outlet tube 21 from the cooling air passage 19 sequentially hits the reflectors 24a to 24e that are arranged so that the depths of the lower portions are sequentially increased, and is reflected upward. To rise. As a result, the cooling air that has flowed into the blower outlet cylinder 21 uniformly hits the entire surface of the induction heating coil 13b disposed on the upper surface thereof, thereby cooling the induction heating coil 13b.

  The reflection guide cylinder 23 has an inner diameter, and the reflection plates 24a to 24e have different heights and heights, that is, height differences between the reflection plates 24a to 24e, for example, the reflection plates 24c and 24a. By changing the gap ΔWc and the height ΔHc, the amount of cooling air can be easily distributed and adjusted, and the cooling air blowing range can be adjusted, and the cooling air is reflected and dispersed on the induction heating coil left 13b. It can be raised almost vertically and applied evenly.

  In the first and second embodiments described above, the example in which the cooling air passage 19 is provided in the induction heating coil left 13b has been described. However, the cooling air passage 19 may also be implemented in the induction heating coil right 13a. it can.

  That is, in FIG. 2 and FIG. 3, the cooling air that has flowed into the main body 2 from the air inlet 7 by driving the blower fan 15 is caused to flow into the substrate case 16 and the control board therein is cooled. Cooling air is sent through the path 19 to the induction heating coil right 13a side.

  However, the cooling air from the blower fan 15 may be divided into the inside of the substrate case 16 and the upper surface side of the substrate case 16, and the induction heating coil right 13a may be cooled by the cooling air on the upper surface side. If the cooling air passage 19 is arranged on the upper surface of the case 16 and the blower fan 15 and the induction heating coil right 13a are connected, the same operation and effect as the above embodiment can be obtained. Further, when the resistance heater center 13c is replaced with an induction heating coil, this can be implemented.

  As described above, according to the present embodiment, the cooling air that has flowed into the blower outlet tube through the cooling air passage is reflected on the respective wall surfaces by the respective reflecting plates, becomes a dispersed flow, rises substantially vertically, and is guided. The air is blown to the center and the periphery of the heating coil and cooled. Further, the other cooling air that does not hit the reflecting plate rises upward along the inner wall of the blower outlet tube, and cools by hitting the induction heating coil substantially vertically. As a result, the entire surface of the induction heating coil is cooled uniformly and efficiently.

  Further, a part of the cooling air flowing into the cooling air passage from the air inlet of the cooling air passage hits the reflecting wall of the reflecting guide tube provided on the upper surface before reaching the air outlet tube, and is substantially perpendicular to the reflecting guide tube. It flows in and flows out to the peripheral edge of the induction heating coil before reaching the blower outlet tube to cool the peripheral edge, and the induction heating coil is further uniformly and efficiently cooled.

  Therefore, unlike the conventional case, there is no problem that the cooling air is concentrated on one side of the induction heating coil and the temperature difference becomes large, and the required amount of cooling air can be minimized, and the cooling structure including the cooling fan is compact. And noise reduction at a low rotation speed of the cooling fan can be realized.
