JP 11-354263 A

  However, in the above-described conventional induction heating cooker, an intake / exhaust path required for cooling the main body 1 can be established simply by dropping the main body 1 into the opening 3 of the cabinet 2 and fixing it. Although the construction is unnecessary and the effect that the intake and exhaust leakage inside the cabinet 2 can be easily prevented is described, this is because the inside of the cabinet 2 is used as the intake space of the induction heating cooker body 1 and the exhaust port 8 is used as the cabinet 2. This is because it is provided on the rear rear surface of the main body 1 which is the outside of the cabinet 2 and the exhaust port is not arranged inside the cabinet 2.

  Although various unspecified items are stored inside the cabinet, for example, when a thin and light film-like object such as a plastic bag or a wrap is put inside the cabinet 2, it is easily controlled by the suction pressure of the cooling fan 6. Cooking, such as sticking to the air inlet 7, cooling capacity decreases due to insufficient cooling air volume, the temperature in the induction heating cooker body 1 rises, the protection device operates, heating stops or heating power decreases However, there was a problem that problems such as interruption or lack of thermal power occurred.

  SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and does not block the intake port with a film-like foreign matter such as a plastic bag or a wrap put in a cabinet, thereby reducing the cooling capacity. An induction heating cooker that does not cause problems such as interruption of cooking and lack of thermal power by operating.

  In order to solve the above-described conventional problems, a heating cooker according to the present invention includes a top plate for placing a cooking container, a plurality of heating units for heating the cooking container, and at least one of the heating units by induction heating. An induction heating means, an energization control device for controlling energization to the induction heating means, an outer case that forms a main body housing below the top plate and incorporates the energization control device and a cooling fan, and the top An exhaust port disposed at the rear of the plate, a first intake port provided on a bottom surface of the outer case close to the cooling fan, and a bottom cover that covers a bottom surface of the outer case, A plurality of second air inlets are provided in a position shifted from the first air inlet, and are incorporated into a cabinet provided with a vent. The cooling fan is installed from the vent provided in the cabinet. When sucking cooling air into the cabinet, even if thin items such as plastic bags or wraps in the cabinet are attracted by the suction of the cooling fan, they are placed on the first air inlet on the bottom of the outer case and the bottom cover. Since the position of the second intake port is shifted, the suction pressure of the cooling fan is difficult to be applied directly to the second intake port, and since the second intake port is distributed, all the second intake ports are Since it becomes difficult to be shielded and the cooling capacity can be secured, the temperature protection of the main body does not operate easily, and it is possible to prevent problems such as interruption of cooking or lack of thermal power.

  The induction heating cooker according to the present invention includes a top plate on which a cooking container is placed, a plurality of heating units for heating the cooking container, induction heating means for induction heating at least one of the heating units, An energization control device that controls energization to the induction heating means, an outer case that forms a main body housing below the top plate and incorporates the energization control device and a cooling fan, and is arranged behind the top plate A cooker body having an exhaust port and an intake port provided on the bottom surface of the outer case adjacent to the cooling fan is partitioned between a cooker installation part having a vent hole directly communicating with the outside air and a storage part. It is used by incorporating it into the cooker installation part of the cabinet partitioned by a plate, and the inside of the cabinet is separated into a cooker installation part and a storage part by a partition plate, and the vents directly communicate with the cooker installation part. Because there, the suction force by the cooling fan reaching the cooling fan from the vent does not act on the housing section of the cabinet, those placed in the receiving portion is not able to shield the air inlet provided in the outer casing. Furthermore, since the inside of the cabinet is separated into a cooker installation part and a storage part by a partition plate, the exhaust pressure of the cooling fan passes through a gap such as a joint part of the outer case and becomes negative pressure by the cooling fan suction force. The waste heat leak to the cooker installation section can be blocked by the partition plate, the waste heat of the cooker body does not reach the storage section in the cabinet, and problems such as the temperature of food in the storage section will not rise .

  The induction heating cooker according to the present invention includes a top plate on which a cooking container is placed, a plurality of heating units for heating the cooking container, induction heating means for induction heating at least one of the heating units, An energization control device that controls energization to the induction heating means, an outer case that forms a main body housing below the top plate and incorporates the energization control device and a cooling fan, and is arranged behind the top plate A cooker body having an exhaust port and an intake port provided on the bottom surface of the outer case adjacent to the cooling fan, a partition plate between a storage unit having a vent hole communicating with the outside air and the cooker installation unit When the cooker body is assembled, it is incorporated in the cooker installation part of the cabinet having a ventilation connection path communicating the storage part and the cooker installation part behind the rear surface of the outer case when the cooker body is incorporated. Intended to be used, external air is introduced into the cooker installation portion side space through the vent connection path from the housing section of the cabinet, it is sucked into the cooker body. The hot air from the cooker body leaks into the space where the cooker is installed, but outside air is introduced into the storage space, so it is sucked into the intake port again almost without diffusing into the storage space, and the temperature of the storage space rises. Can be suppressed.

  The induction heating cooker according to the present invention ensures a cooling capacity by preventing all the intake ports for taking in cooling air from being blocked by a thin foreign matter such as a plastic bag or a wrap put in a cabinet incorporating the cooker body. At the same time, it is possible to prevent problems such as the operation of the temperature protection device of the main body to interrupt cooking or the lack of thermal power.

  According to a first aspect of the present invention, there is provided a top plate on which a cooking container is placed, a plurality of heating parts for heating the cooking container, induction heating means for induction heating at least one of the heating parts, and the induction heating means An energization control device that controls energization, an outer case that forms a main body housing below the top plate and incorporates the energization control device and a cooling fan, an exhaust port disposed behind the top plate, and A first air inlet provided on the bottom surface of the outer case close to the cooling fan; and a bottom cover that covers the bottom surface of the outer case; and a plurality of positions at positions shifted from the first air inlet of the bottom cover. When the cooling fan sucks cooling air into the main body from the ventilation holes provided in the cabinet, the second air inlets are distributed and used in the cabinet with ventilation holes. Even if thin items such as plastic bags or wraps are drawn by the suction of the cooling fan, the position of the first air inlet provided on the bottom surface of the outer case and the second air inlet provided on the bottom cover are shifted. Therefore, the suction pressure of the cooling fan is difficult to be applied directly to the second intake port, and since the second intake ports are distributed, all the second intake ports are difficult to be shielded, and the cooling capacity can be secured. Therefore, the temperature protection of the main body does not operate easily, and it is possible to prevent problems such as cooking being interrupted and insufficient thermal power.

  In the second invention, in particular, the bottom cover of the first invention is formed in a container shape having an upper surface opened, a second air inlet is arranged on the vertical wall surface of the bottom cover, and the upper surface opening is formed in the first air intake. Since the second intake ports are dispersed and provided near the outer periphery of the main body, shielding the entire second intake port will cause foreign matter to be adsorbed to the entire bottom surface. The second intake port is hardly shielded, and even if foreign matter is adsorbed on the bottom surface of the main body, a part of the second intake port is shielded. It is possible to reduce the fact that the temperature protection device works and the operation stops.

  According to a third aspect of the present invention, there is provided a top plate on which a cooking container is placed, a plurality of heating units for heating the cooking container, induction heating means for induction heating at least one of the heating parts, and the induction heating means. An energization control device that controls energization, an outer case that forms a main body housing below the top plate and incorporates the energization control device and a cooling fan, an exhaust port disposed behind the top plate, and A cooker body provided with an air inlet provided on the bottom surface of the outer case close to the cooling fan is partitioned by a partition plate between a cooker installation part having a vent hole directly communicating with the outside air and a storage part. The cabinet is used by being incorporated in the cooker installation part, and the cabinet is separated by a partition plate into the cooker installation part and the storage part, and the vent is directly connected to the cooker installation part. Suction force by the cooling fan leading to et the cooling fan does not act on the housing section of the cabinet, those placed in the receiving portion is not able to shield the air inlet provided in the outer casing. Furthermore, since the inside of the cabinet is separated into a cooker installation part and a storage part by a partition plate, the exhaust pressure of the cooling fan passes through a gap such as a joint part of the outer case and becomes negative pressure by the cooling fan suction force. The waste heat leak to the cooker installation section can be blocked by the partition plate, the waste heat of the cooker body does not reach the storage section in the cabinet, and problems such as the temperature of food in the storage section will not rise .

  The fourth aspect of the invention is particularly that the cooker installation part and the storage part space of the third invention are blocked by a partition plate, and a power outlet connected to the cooker body is incorporated in a cabinet stored in the cooker installation part. Because it is used, there is no need for a gap in the code processing on the partition plate, and the suction force from the cooling fan from the ventilation port to the cooling fan does not act on the storage part, but what is put in the storage part uses the suction port of the cooker body Since it does not shield, the storage space in the cabinet is sealed while keeping the induction cooker cooled, and the insect-proof effect of the storage can be enhanced.

  The fifth invention is particularly used by incorporating the partition plate of the third invention into a cabinet in which the depth of the partition plate is substantially the same as the rear surface of the outer case. And the cabinet vent is directly connected to the cooker installation section, so the suction force from the cooling fan from the vent to the cooling fan does not act on the cabinet storage section and is put in the storage section. Is the same as that of the third invention, and the inside of the cabinet is a partition plate whose depth is substantially the same position as the rear surface of the outer case. Therefore, the waste heat that leaks to the cooker installation through the gap of the outer case joint due to the exhaust pressure of the cooling fan becomes negative pressure due to the suction of the cooling fan above the partition plate. The Since sucked into that cooking installation side, the waste heat of fluid leaks from the gap between the outer casing is difficult at the storage unit. In addition, since the partition plate is provided in a range that almost covers the bottom of the cooker body, it is difficult for the cooker body waste heat to reach the storage part in the cabinet, and the temperature of food in the storage part increases. The effect that does not occur can be maintained.

  In addition, since the partition plate is halfway inside the cabinet, the cooker installation part and the storage part communicate with each other at the rear part of the cabinet to create a wide part. Installation is free.

  According to a sixth aspect of the present invention, there is provided a top plate on which the cooking container is placed, a plurality of heating units for heating the cooking container, induction heating means for induction heating at least one of the heating parts, and the induction heating means. An energization control device that controls energization, an outer case that forms a main body housing below the top plate and incorporates the energization control device and a cooling fan, an exhaust port disposed behind the top plate, and A cooker body provided with an air inlet provided near the cooling fan and provided on the bottom surface of the outer case, the storage part having a vent communicating with the outside air and the cooker installation part are partitioned by a partition plate, It is used by being incorporated in the cooker installation part of the cabinet having a ventilation connection path that communicates the storage part and the cooker installation part behind the rear surface of the outer case when the cooker body is incorporated, Air is led to the ventilation connection path cooker installing portion side space through the housing part of the cabinet, it sucked inside the cooker body. The hot air from the cooker body leaks into the space where the cooker is installed, but outside air is introduced into the storage space, so it is sucked into the intake port again almost without diffusing into the storage space, and the temperature of the storage space rises. Can be suppressed.

  In the seventh invention, in particular, the storage space of any one of the third, fifth, and sixth inventions is a single-layer or multi-layer storage, and at least the upper surface of the uppermost storage is covered with a partition plate. It is used by being incorporated in the cabinet, and it is possible to increase the storage efficiency by freeing the storage configuration while suppressing the temperature rise of the storage section under the cooker body.

An operation circuit unit 22 is locked and fixed to the outer shell 17 inside the main body corresponding to the operation portions 19a, 19b, and 19c. Circuit units 23a and 23b, which are energization control devices for the heating coils 20a and 20b, are arranged below the heating coils 20a and 20b, respectively, and in front of the circuit units 23a and 23b, at positions below the operation circuit unit 22, respectively, are cooling fans 24a. , 24b, and on the bottom surface of the outer shell 17 below, there are first intake ports 25a, 25b arranged close to the cooling fans 24a, 24b as intake ports for taking in air.

  In the circuit units 23a and 23b, heat sinks 26a and 26b for radiating switching elements 27a and 27b (not shown), which are components constituting an inverter circuit corresponding to the left and right heating coils 20a and 20b, and a resonance capacitor 28a 28b and other parts are mounted.

  Also, in each of the circuit units 23a and 23b, first temperature detection elements 29a and 29b fixed to the heat sinks 26a and 26b, second temperature detection elements 30a and 30b disposed behind the resonance capacitors 28a and 28b, and Third temperature detecting elements 31a and 31b arranged at the rear of the circuit units 23a and 23b are arranged. The first temperature detection elements 29a and 29b are fixed to the heat sinks 26a and 26b and directly detect the temperature of the switching elements 27a and 27b, but the surface of the circuit units 23a and 23b close to the terminals of the switching elements 27a and 27b.

  The third temperature detection elements 31a and 31b detect the ambient temperature in the air behind the circuit units 23a and 23b, but may be directly attached to the surface of the circuit units 23a and 23b.

  The plate frame 16 surrounds the top plate 15 so that the end surface of the top plate 15 is not exposed, and at the same time, an exhaust port 32 is provided in the vertical wall of the rear side, and the inside of the main body 11 is the back surface of the top plate 15 and the outer shell 17. It communicates through a gap with a flange-like bent portion at the upper end of the. The entire circumference of the top plate 15 is larger than the outer shape of the outer case 17 below the top plate 15.

  The front surface of the cabinet 12 is covered with a surface material upper 33 that covers the outer case 17 of the main body 11 and a surface material lower 35 that covers the front surface of the storage portion 34 that is a drawer at the lower portion of the surface material upper 33. . The gap between the upper face material 33 and the lower face material 35 is often about 3 to 5 mm in order to avoid interference between the two. If the standard width of the cabinet 12 incorporating the cooker body 11 is 60 cm, A gap area of about 15 to 30 square centimeters is secured between the face material upper 33 and the face material lower 35, and this gap area becomes a vent 36 for introducing outside air into the cabinet 12.

The total area of the second intake port 37 is larger than the total area of the first intake ports 25a and 25b.

  In addition, since the bottom surface of the main body 1 is formed in a double bottom shape by the bottom cover 38 and the first intake ports 25a and 25b are closed immediately below, the suction pressure loss of the cooling fans 24a and 24b is reduced. The clearance between the bottom surface of the outer case 17 and the bottom cover 38 is preferably about 10 to 30 mm.

  About the induction heating cooking appliance comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The second intake port 37 is not disposed directly below the first intake ports 25a and 25b, and is shifted from the first intake port 25a and 25b. Therefore, the suction pressure of the first intake ports 25a and 25b is directly applied to the second intake port 37. In addition, since the total area of the second air inlet 37 is larger than the total area of the first air inlets 25a and 25b, the suction pressure of the second air inlet 37 is reduced. Therefore, even if a film-like light foreign matter such as a plastic bag or a food wrap is stored in the storage portion 34 of the cabinet 12, it is difficult for the foreign matter to be adsorbed to the second air inlet 37 and at the same time the second air inlet 37. Are larger than the total area of the first intake ports 25a and 25b, and the air intake speed of the second intake port 37 is the same as that of the first intake ports 25a and 25b. It becomes difficult to adsorb foreign matter. In addition, since the area of the second air inlet 37 is larger than that of the first air inlets 25a and 25b and is arranged in a distributed manner, even if foreign matter is adsorbed on the bottom surface of the bottom cover 38, the second air inlet 37 Even if a part of 37 is shielded, the entire surface is hardly shielded.

  As described above, according to the present embodiment, not all of the second air inlets 37 are shielded, the cooling capacity is ensured, and the temperature rise of the heat generating components such as the switching elements 27a and 27b is suppressed, A plurality of temperature detection elements such as the first temperature detection elements 29a and 29b detect an abnormal temperature rise, and a temperature protection device (not shown) works to reduce the stoppage of the operation, and is easy to use induction heating cooking Can be provided.

(Embodiment 2)
FIG. 5 is a cross-sectional view of the induction heating cooker according to the second embodiment of the present invention, and FIG. 6 is a bottom perspective view of the induction heating cooker. Note that the same portions as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  This embodiment is different from the first embodiment only in the configuration of the bottom cover, and the other configurations are the same.

  5 and 6, the bottom cover 41 is formed in a container shape with an open top surface, and a second air inlet 46 is disposed on each of the vertical wall surfaces 42, 43, 44, 45, and the top surface opening is the bottom surface of the outer case 17. It is attached so as to communicate with the first air inlets 25a, 25b arranged on the outer side of the outer casing 17 and to cover almost the entire bottom surface of the outer case 17.

  About the induction heating cooking appliance comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The second air inlets 46 provided on the vertical wall surfaces 42, 43, 44, 45 of the bottom cover 41 are provided near the outer periphery of the main body 11 and at positions separated from each other. It is almost impossible for the intake port 46 to be completely blocked by foreign matter. That is, the fact that the entire second air inlet 46 is shielded means that foreign matter is adsorbed to the entire bottom cover 41, and it is considered that the cabinet 12 has a standard width dimension of 60 cm and a depth dimension of 60 cm or more. In order to shield all of the second air inlets 46, the vertical wall surface of the bottom cover 41 is covered with a foreign substance corresponding to these sizes, and such a case hardly occurs.

  Therefore, when there is a foreign object on the bottom surface of the main body 11, even if a part of the second air inlet 46 is shielded, the whole is not easily shielded and the temperature rise of the heat generating components such as the switching elements 27a and 27b is surely suppressed. In addition, a plurality of temperature detection elements such as the first temperature detection elements 29a and 29b detect an abnormal temperature rise, the temperature protection device is activated, the operation is stopped, and an easy-to-use induction heating cooker is provided. it can.

  Note that if the total opening area of the second intake port 46 is made larger than that of the first intake ports 25a and 25b, the suction air speed at the second intake port 6 becomes higher than that of the first intake ports 25a and 25b. The foreign matter adsorption prevention effect can be further enhanced.

  In addition, since the bottom surface of the main body 1 has a double bottom shape and the structure directly under the first intake ports 25a and 25b is closed, the bottom surface of the outer case 17 is reduced in order to reduce the suction pressure loss of the cooling fans 24a and 24b. It is desirable to secure a clearance of 10 mm to 30 mm between the bottom cover 38 and the bottom cover 38.

(Embodiment 3)
FIG. 7 is a cross-sectional view showing a state where the induction heating cooker according to the third embodiment of the present invention is incorporated in a cabinet, and FIG. 8 is a bottom perspective view of the induction heating cooker.

  This embodiment differs from the first embodiment only in that the bottom cover is abolished and the cabinet configuration is changed, and the other configurations and functions are the same as the first embodiment, and thus the same. Reference numerals are assigned and explanations thereof are omitted.

  7 and 8, first intake ports 25 a and 25 b are provided on the bottom surface of the outer case 17 of the main body 11. The cabinet 12 is provided with a partition plate 53 that completely partitions the cooker installation unit 51 and the storage unit 52, and the cooker installation unit 51 is provided with a vent 54 that communicates directly with the outside air.

  The vents 54 are formed between the gap between the back surface side of the work top 13 at a position deeper than the front end of the work top 13 of the cabinet 12 and the upper surface material 55 of the cabinet uppermost drawer, and between the upper surface material 55 and the crosspiece 56. Are provided on a crosspiece 56 at the back of the air passage 58 formed by a gap formed by the packing 57.

  The gap between the back side of the work top 13 and the top surface 55 of the cabinet 12 uppermost drawer is often about 3 to 5 mm in view of the cabinet 12, and if the standard width of the cabinet 12 incorporating the main body 11 is 60 cm, A clearance area of about 15 to 30 square centimeters is secured.

  The power outlet 59 connected to the cooker body 11 is fixed in the space of the cooker installation part 51 so that the power plug 60 faces the work top 13 side of the cabinet 12 and when the power plug 60 is inserted, The gap A between the plug 60 and the partition plate 53 is set to be shorter than the length of the plug blade (not shown) of the power plug 60.

  About the induction heating cooking appliance comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The inside of the cabinet 12 is completely separated into the cooking device installation part 51 and the storage part 52 by the partition plate 53, and the ventilation hole 54 of the cabinet 12 communicates directly with the cooking appliance installation part 51. 24b, the suction force by the cooling fans 24a and 24b does not act on the storage section 52 of the cabinet 12, and a thin film-like material such as a plastic bag or food wrap placed in the storage section 52 is sucked. There is no.

  Moreover, since what was put in the accommodating part 52 is hold | suppressed by the partition plate 53 upwards, the inlet ports 25a and 25b of the main body 11 are not shielded. Furthermore, the exhaust heat from the cooling fan 24a, 24b of the main body 11 passes through the gaps such as the joints of the outer case 17, and the waste heat to the cooker installation 51 where the cooling fan 24a, 24b has a negative pressure due to the suction force. Although there is a leak, the waste heat leak is blocked by the partition plate 53 so as not to reach the storage portion 52, so that a problem such as an increase in the temperature of food stored in the storage portion 52 does not occur.

  In addition, since the power plug 60 is connected to the power in the cooker installation unit 51 which is the space above the partition plate 53, the processing of the power cord 61 can be completed in the cooker installation unit 51, and the partition plate 53 is subjected to code processing. No gap is required. As a result, the space of the storage portion 52 in the cabinet 12 is sealed, and the insect repellent effect that prevents cockroaches and the like from entering the storage portion 52 can be enhanced.

  Further, the power outlet 59 is fixed so that the power plug 60 faces the work top 13 side of the cabinet 12, and when the power plug 60 is inserted, the gap A between the power plug 60 and the partition plate 53 is larger than the length of the plug blade. Since the power plug 60 hits the partition plate 53 when the power plug 60 is pulled out, the power plug 60 can be prevented from being pulled out by connecting the power plug 60 even if the power plug 60 is not visible on the partition plate 53. There is no defect.

  In the present embodiment, the depth of the partition plate 71 is set to the same position as the rear surface of the outer case 17. The inside of the cabinet 12 is separated into the cooking device installation part 51 and the storage part 52 by the partition plate 71, but the depth of the partition plate 71 is substantially the same position as the rear surface of the outer case 17, so Between the width B to the rear wall 12a of the cabinet 12, the cooking device installation part 51 and the storage part 52 are in communication.

  Thereby, the inside of the cabinet 12 is largely separated by the partition plate 71 into the cooker installation part 51 and the storage part 52, and the vent 54 of the cabinet 12 communicates directly with the cooker installation part 51. The suction force by the cooling fans 24 a and 24 b reaching 24 a and 24 b is less likely to act on the storage portion 52 of the cabinet 12. Accordingly, it is difficult to block the first intake ports 25a and 25b of the main body 11 from the storage unit 52.

  In addition, since the inside of the cabinet 12 is separated into the cooker installation portion 51 and the storage portion 52 by a partition plate 71 whose depth is substantially the same as the rear surface of the outer case 17, the cooling fan 24a of the main body 11, Due to the exhaust pressure of 24b, the waste heat leaked to the cooker installation part 51 through the gap of the joint portion of the outer case 17 becomes negative pressure by the suction force of the cooling fans 24a, 24b on the upper side of the partition plate 71. It is sucked to the cooker installation part 51 side on the upper side of the partition plate 72.

  Waste heat leaked to the cooker installation part 51 through a gap such as a joint part of the outer case 17 is received by the partition plate 71 because the partition plate 71 is provided in a range almost covering the bottom surface of the cooker body 11. Since the air is sucked into the first suction ports 25a and 25b, it is difficult to reach the storage portion 52 in the cabinet 12, and the effect of not causing a problem such as an increase in the temperature of food stored in the storage portion 52 can be maintained. .

  Further, the partition plate 57 has a length halfway inside the cabinet 12, and a rear portion in the cabinet 12 has a width B portion where the cooker installation portion 51 and the storage portion 52 communicate with each other. The outlet 59 can be installed freely, and the installation property is good.

  In the present embodiment, the vent connection path 82 through which the cooker installation unit 51 and the storage unit 52 communicate with each other between the rear end of the partition plate 81 separating the cooker installation unit 51 and the storage unit 52 from the width C. In addition, the depth of the partition plate 81 is set behind the rear surface of the outer case 17, and a vent 83 that communicates the outside air with the storage portion 52 is provided below the partition plate 81.

  As a result, outside air is guided from the storage unit 52 side of the cabinet 12 to the space on the cooker installation unit 51 side through the ventilation connection path 82 having a width C provided in the back of the partition plate 81, and the cooling fan 24 a in the main body 11. Inhaled by 24b. Since the outside air is introduced into the space of the storage portion 52, the hot air of the main body 11 leaks into the space on the cooker installation portion 51 side, but the air flows upward through the ventilation connection path 82 by the cooling fans 24a and 24b. The hot air is sucked into the first intake ports 25a and 25b again without almost diffusing into the space. As a result, the temperature rise of the storage unit 52 can be suppressed.

FIG. 11: is sectional drawing which shows the state which incorporated the induction heating cooking appliance in the 6th Embodiment of this invention in the cabinet. In addition, about the same part as the said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In this embodiment, the storage unit 93 space partitioned by the cooker installation unit 91 for installing the main body 11 and the partition plate 92 is defined as an upper storage unit 94 and a lower storage unit 95 composed of two drawers, and at least the upper storage unit is stored. A partition plate 92 is provided in a range that covers the upper surface of the warehouse 94, and the other configuration is the same as that of the fourth embodiment.

  With the above-described configuration, the upper surface of the upper storage 94 in the uppermost portion of the storage unit 93 below the main body 11 is blocked by the partition plate 92, so that the temperature rise in the upper storage 94 can be suppressed. In addition, since the lower storage 95 is mostly closed by the upper storage 94 and the upper storage 94 is between the partition plate 92, the hot air is difficult to reach, and the temperature of the entire storage unit 93 is reduced. While suppressing the rise, the storage section 93 can be freely configured to reduce the unused space and increase the storage efficiency.

  In the present embodiment, the storage section 93 has a two-layer drawer structure, but the present invention is not limited to this, and the same is applicable if the upper surface of the uppermost drawer is blocked by the partition plate 92 in three or more layers. The effect of can be obtained. Further, the same effect can be obtained even if the storage portion 93 has a single-layer drawer configuration and the upper surface of the drawer is closed by the partition plate 92.

  Further, in the present embodiment, the vent 54 leading to the inside of the cabinet 12 is configured to communicate with the cooker installation unit 91, but the present invention is not limited to this, and the vent 54 is a storage unit 93 below the partition plate 92. The same effect can be obtained if the uppermost layer of the multi-layered storage constructed as a drawer is configured to close its upper surface with a partition plate.

  As described above, in the induction heating cooker according to the present invention, the first air inlet provided in the bottom surface of the outer case of the cooker body is shielded by foreign matter such as a plastic bag or a wrap placed in the cabinet storage section. Since there is no problem and the cooling capacity can be secured, the temperature protection device of the main body operates to prevent problems such as cooking being interrupted or lack of thermal power, and the outside air is used for cooling and / or drying In addition to having a function of incorporating, it can be widely applied to various devices such as a cooking device and a drying device that are used by being incorporated in a kitchen cabinet or the like.
