  The first engagement portion 133 is disposed at a position that does not overlap the opening 151 of the lower frame 15 in a front view. For this reason, the main flow of the exhaust flow that exits from the opening 151 is less likely to contact the first engagement portion 133, so that the inhibition of the flow of the exhaust flow by the first engagement portion 133 can be reduced, and the increase in pressure loss is suppressed. can do. Further, the width between the adjacent first engaging portions 133 is equal to or larger than the width in the left-right direction of each opening 151 of the lower frame 15. For this reason, the reduction | decrease of the airflow cross-sectional area of exhaust flow can be suppressed, and the raise of a pressure loss can be suppressed.

  FIG. 11 is a cross-sectional view of the cooking device 100 according to Embodiment 1 in the front-rear direction. In FIG. 11, the left side of the drawing shows the front side of the cooking device 100, and the right side of the drawing shows the rear side of the cooking device 100. A plurality of air inlets 6 of the main body housing 1 are provided in a portion adjacent to the front wall of the front wall and the bottom surface of the main body housing 1. The air inlet 6 is disposed so as to form a substantially linear flow path between the air inlet 6 of the blower 8 and is connected to the air inlet 6 and the air inlet of the air fan 8 in an airtight manner. Room temperature air outside the main body housing 1 can be sucked into the main body housing 1 while suppressing pressure loss. In the blower 8 of the present embodiment, a suction port is formed on the lower surface of the scroll casing that houses the sirocco fan, and the blower outlet is disposed on the rear side of the suction port. The blower outlet of the blower 8 is disposed on the front side of the heating coil unit 7 in the front-rear direction and on the lower side of the heating coil unit 7.

  FIG. 12 is an enlarged view of the vicinity of the rear frame 13 of FIG. In FIG. 12, the air flow in the vicinity of the rear frame 13 is conceptually indicated by arrows. A first exhaust air passage 20 is formed below the upper wall 131 of the rear frame 13 between the upper surface of the lower frame 15. The first exhaust air passage 20 is an air passage connecting the inside of the main body housing 1 and the first exhaust port 14.

  The upper end portion of the first shielding portion 153 of the lower frame 15 is disposed at a position higher than the lower end portion of the side wall 132 of the rear frame 13, and is substantially slit-like formed below the lower end portion of the side wall 132 when viewed from the back. The inside of the first exhaust port 14 is shielded by the first shielding part 153. For this reason, the designability when the heating cooker 100 is seen from the back side can be improved. Further, by disposing the upper end of the first shielding part 153 at a position higher than the lower end of the side wall 132, tableware and cooking equipment such as a knife and fork are inserted into the main body housing 1 from the first exhaust port. It is possible to prevent damage due to internal damage or contact with a charged part.

  The pair of engaging pieces projecting downward that constitute the first engaging portion 133 of the rear frame 13 detachably holds the first shielding portion 153 of the lower frame 15 by elastic force. Further, the pair of engaging pieces constituting the second engaging portion 134 of the rear frame 13 detachably holds the second shielding portion 154 of the lower frame 15 by an elastic force. Furthermore, in the present embodiment, the upper end portion of the second shielding portion 154 of the lower frame 15 is provided with a bent portion that is bent downward, and this bent portion is the second engaging portion 134. Is inserted between a pair of engaging pieces. For this reason, the bending part of the upper end part of the 2nd shielding part 154 acts as a leaf | plate spring, the 2nd engaging part 134 is urged | biased outside, and it couple | bonds with the stable force while improving attachment / detachment. Thus, by providing a pair of engagement structures on the rear frame 13 and the lower frame 15, even if a cooking utensil such as a pan or a frying pan collides with the rear frame 13, the rear frame 13 is separated from the lower frame 15 by the impact. It can be prevented from coming off.

  The circuit board 16 is not exposed below the opening 151 of the lower frame 15, and a substrate case 17 is interposed between the opening 151 and the circuit board 16. Thus, by covering the circuit board 16 disposed below the opening 151 with the board case 17, liquid such as water or oil dropped through the opening 151 and the draining portion 152 travels down the board case 17. Since it flows to the side and does not contact the circuit board 16, the failure of components mounted on the circuit board 16 is suppressed, and the quality and reliability of the product can be improved.

  A drain port 19 is formed on the bottom surface of the main body housing 1 below the opening 151 of the lower frame 15. Liquid such as water or oil that has flowed into the main body housing 1 from the opening 151 is discharged to the outside of the main body housing 1 through the drain port 19. For this reason, it is possible to suppress the liquid from being accumulated in the lower part in the main body casing 1, and to avoid the failure of the components mounted on the circuit board 16 due to the liquid being immersed in the circuit board 16, thereby improving the quality and reliability of the product. Can be increased.

  Since the 1st shielding part 153 is provided in the back side rather than the opening 151 of the lower frame 15, the penetration | invasion into the main body housing | casing 1 of the liquid etc. which flowed along the kitchen top plate 201 can be suppressed. . Even if the liquid passes over the first shielding part 153 and enters the inside from the opening 151, the liquid that has entered through the opening 151 is not located because the opening 151 is located above the drain outlet 19 of the main body housing 1. Easily discharged from the main body casing 1. For this reason, the failure and damage by the immersion of the liquid of the components accommodated in the main body housing | casing 1 can be suppressed. Further, even if the liquid avoids the opening 151 and travels along the upper surface of the lower frame 15, the second shielding portion 154 is provided in front of the opening 151 of the lower frame 15, so that further inflow of the liquid can be prevented. Can be suppressed. Since the second shielding part 154 of the present embodiment is provided without interruption in a range longer than the width of the main body housing 1, the liquid is applied to the circuit board 16 or the heating coil unit by the bank effect of the second shielding part 154. 7 can be prevented from contacting.

  The dimension (a) in the front-rear direction of the lower frame 15 along the flow direction of the exhaust flow is longer than the dimension (b) in the height direction of the first exhaust air passage 20. Here, the dimension (b) in the height direction of the first exhaust air passage 20 is more specifically the inner dimension between the lower surface of the upper wall 131 of the rear frame 13 and the upper surface of the lower frame 15. By adopting such a dimensional relationship, the flow passage cross-sectional area at the opening 151 that is the inlet of the exhaust flow to the first exhaust air passage 20 is made larger than the flow passage cross-sectional area in the first exhaust air passage 20. It is possible to increase the cooling efficiency by reducing the pressure loss and increasing the exhaust flow rate.

  FIG. 13 is a diagram for explaining a modified example of the heating cooker 100 according to the first embodiment, and is an enlarged view of the same portion as FIG. 12. The example shown in FIG. 13 is different from FIG. 12 in that a flange portion 135 is provided downstream of the side wall 132 of the rear frame 13 in the exhaust flow. The flange 135 is connected to the upper wall 131 and extends to the back side from the side wall 132. By providing such a flange part 135, the first exhaust port 14 is hardly visible from the periphery of the heating cooker 100, and the design of the heating cooker 100 can be improved. In addition, the specific shape of this collar part 135 is an example, and the same effect can be acquired if it is a shape which covers the downstream side of the side wall 132 from the top. Further, in the configuration provided with the flange 135 shown in FIG. 13, the side wall 132 functions as a drainage portion of the liquid transmitted from the upper surface of the rear frame 13, so that liquid from the first exhaust port 14 into the main body housing 1 can be obtained. Can be suppressed.

  In the heating cooker 100 configured as described above, when the user operates the operation unit 4 to set the heating power of the heating port 3 on which the object to be heated is placed and instruct to start heating, the control circuit of the circuit board 16 and When the drive circuit operates, a high frequency current flows through the heating coil unit 7. When the current flows, a line of magnetic force is generated from the heating coil unit 7, an eddy current is generated in a heated object such as a pan or a frying pan placed on the top plate 2, and the heated object itself generates heat.

  When the control circuit and the drive circuit of the circuit board 16 are operated, components such as the choke coil constituting the power supply circuit and the IGBT and the diode bridge constituting the inverter circuit are self-heated and the temperature rises. Further, the coil winding, ferrite, and magnetic shield ring constituting the heating coil unit 7 also self-heat and the temperature rises. In order to maintain the functions of the circuit board 16 and the heating coil unit 7, it is necessary to suppress the temperature rise within a predetermined temperature. For this reason, a temperature sensor is provided in the heat generating part of the circuit board 16 or the heating coil unit 7, and the control circuit operates the blower 8 based on temperature information from the temperature sensor and a thermal power setting in the operation unit 4. .

  When the blower 8 operates, air flows into the storage unit 202 from the gap between the front surface of the kitchen cabinet 200 and the main body housing 1 by the suction force of the blower 8, and the introduced air flows between the kitchen cabinet 200 and the main body housing 1. Flows toward the air inlet 6 provided on the front surface and the bottom surface of the main body housing 1 and flows into the main body housing 1 from the air inlet 6. The air that has flowed into the main body housing 1 is sucked into the blower 8 through a substantially airtight air passage formed between the intake port 6 and the suction port of the blower 8, and enters the substrate case 17 from the blowout port of the blower 8. It is sent out as cooling air.

  The cooling air blown from the blower outlet of the blower 8 flows out from the second outlet 172 provided in the substrate case 17 and the first outlet 171 disposed on the rear side of the second outlet 172. It is divided into the flow that flows out of The electrical component, the electronic component, and the heat dissipation means 161 mounted on the circuit board 16 are disposed between the second outlet 172 and the first outlet 171 in the flow direction of the cooling air in the board case 17. By providing a plurality of first outlets 171 and second outlets 172 in the substrate case 17 and diverting the cooling air, the components arranged at different places such as the heating coil unit 7 and the components on the circuit board 16 It is possible to supply a cooling air having a low temperature of about room temperature with little temperature rise due to the heat generated by other components. Therefore, the cooling efficiency of the parts to be cooled can be increased. In addition, by dividing the flow into the plurality of first outlets 171 and second outlets 172, the flow path can be enlarged and the wind speed can be lowered, which has an effect of suppressing pressure loss.

  Cooling air that is sent out from the blower 8 and exits from the first outlet 171 and the second outlet 172 exits from the main body housing 1 through the opening 151 of the lower frame 15 and is below the upper wall 131 of the rear frame 13. It flows through the first exhaust air passage 20 formed on the side, and is exhausted through the slit-shaped first exhaust port 14 formed on the lower side of the lower end of the side wall 132 of the rear frame 13. By making the flow path of the cooling air from the blower outlet of the blower 8 to the first exhaust port 14 into a substantially linear flow path connecting the lower front part and the upper rear part of the main body housing 1, An increase in pressure loss can be suppressed. Moreover, since a flow path length can be shortened, pressure loss is reduced, the efficiency of the air blower 8 can be improved, and the low-noise heating cooker 100 can be obtained. In addition, the flow path from the intake port 6 to the suction port of the blower 8 is also configured linearly, and both the inflow side and the outflow side of the blower 8 are linear air passages. A low-noise heating cooker 100 can be obtained.

  As described above, the heating cooker 100 according to the present embodiment passes through the top plate opening of the kitchen top plate 201 provided on the upper surface of the kitchen cabinet 200 to the storage unit 202 of the kitchen cabinet 200 to at least one of the main body casing 1. It is a built-in type heating cooker in which the part is stored. The heating cooker 100 includes a main body housing 1, a top plate 2 provided on the upper surface of the main body housing 1, and a rear frame 13 provided on the upper side of the top plate 2 along one side of the top plate 2. Prepare. In the main body casing 1, an air inlet 6 is formed at a position below the kitchen top plate 201 in a state where the main body casing 1 is stored in the storage unit 202. The rear frame 13 includes an upper wall 131 that extends outward from one side of the top plate 2, and a side wall 132 that extends downward from the outer end of the upper wall 131. The side wall 132 has such a length that the lower end of the side wall 132 does not contact the kitchen top plate 201 in a state where the main body housing 1 is stored in the storage unit 202, and the gap between the lower end of the side wall 132 and the kitchen top plate 201 The first exhaust port 14 is formed, and the first exhaust air passage 20 that communicates the first exhaust port and the inside of the main body housing 1 is provided below the upper wall 131 of the rear frame 13.

  Since the gap between the lower end portion of the side wall 132 of the rear frame 13 and the kitchen top plate 201 is the first exhaust port 14, it is more conspicuous than the case where an exhaust hole is provided in the member constituting the outline of the heating cooker 100. Difficult exhaust ports can be provided. For this reason, even if the heating cooker 100 of this Embodiment is installed in an island kitchen etc. and the whole outer periphery of the upper part of the heating cooker 100 is visible, favorable design property can be maintained. In addition, since the formation of the first exhaust port 14 does not require drilling a member constituting the outer shell, edge portions such as burrs and burrs associated with the drilling are not generated, and the first exhaust port exposed to the outside is formed. 14 exterior quality can be improved. Further, the side wall 132 of the rear frame 13 forming the first exhaust port 14 has a structure that can be produced by extrusion molding or pressing. When manufactured by extrusion molding, the side wall 132 does not have an edge, and when manufactured by press working, it is possible to easily take an edge countermeasure, so that it is difficult for the user to feel uncomfortable.

  Moreover, since the side wall 132 of the rear frame 13 that forms the first exhaust port 14 has a shape protruding downward, the side wall 132 can also function as a drainer. For this reason, even if liquid such as boiling juice spilled by cooking on the top plate 2 flows along the rear frame 13, the liquid reaching the side wall 132 of the rear frame 13 flows downward due to gravity. It is possible to prevent the liquid from falling through the inside of the rear frame 13.

  In addition, since the inlet 6 is formed at a position below the kitchen top plate 201 in a state where the main body housing 1 is stored in the storage unit 202, liquids such as oily smoke, steam and boiled juice accompanying heating It is difficult to enter the main body housing 1. When an exhaust flow is blown out from the first exhaust port 14 formed on the upper side of the kitchen top plate 201, liquids such as dust and boiled juice are flown by the air flow exhausted without being sucked from the first exhaust port 14, and are discharged. Since the first exhaust port 14 is moved away from the first exhaust port 14, even when the slit-shaped first exhaust port 14 is provided, it is possible to prevent liquids such as dust and broth from entering the main body housing 1. In addition, by sucking from the kitchen cabinet 200 and exhausting from the top of the kitchen top plate 201, the temperature rise in the kitchen cabinet 200 is suppressed, and deterioration due to the heat of the food stored in the kitchen cabinet 200 is suppressed. In addition, it is possible to reduce the internal odor and to reduce the user's discomfort due to the odor.

  Further, the first exhaust port 14 is provided on a side different from the front side where the operation unit 4 is disposed, and the first exhaust port 14 is opposed to the front side and the rear frame 13 across the heating coil unit 7. It is formed using. Thus, since it does not exhaust to the operation part 4 side, ie, the side where the user who cooks, stands, comfort of the user who cooks can be maintained. The first exhaust port 14 is formed between the lower end of the side wall 132 of the rear frame 13 and the upper surface of the kitchen top plate 201, and the airflow that has passed through the first exhaust air passage 20 is guided to the inner surface of the side wall 132 and generally faces downward. Is exhausted. For this reason, even when there is a user on the back side of the heating cooker 100, the airflow guided downward is difficult to be blown near the user's face, and the discomfort caused by the exhaust coming into contact with the user can be reduced. it can.

  In addition, a lower frame 15 is provided along the rear side of the top plate 2 and opposed to the lower side of the rear frame 13. The lower frame 15 protrudes upward and faces the first exhaust port 14. The 1st shielding part 153 was provided. For this reason, even when liquid such as boiled broth from a cooking utensil such as a pan flows out on the kitchen top plate 201 by cooking on the top plate 2, the liquid is blocked by the first shielding portion 153. Therefore, it is possible to reduce the inflow of the liquid onto the lower frame 15 on the inner side of the first shielding part 153, and there is an effect of suppressing failure and damage due to the penetration of the liquid or the like into the main body housing 1.

  In the present embodiment, the upper end of the first shielding part 153 is located higher than the lower end of the side wall 132 of the rear frame 13. For this reason, the inside of the main body housing 1 is shielded by the side wall 132 and the first shielding portion 153 and the inside of the main body housing 1 is not exposed, and the inside of the main body housing 1 cannot be seen even if the user visually observes the first exhaust port 14 from the outside. For this reason, there is an effect that the design property is enhanced and the appearance quality is improved. Even if a cooking tool such as a knife or fork is mistakenly inserted into the first exhaust port 14, the first shielding portion 153 becomes a wall, so that foreign matter can be prevented from entering the main body casing 1. can do.

  Moreover, the heating cooker 100 of this Embodiment was provided with the circuit board 16 and the board | substrate case 17 in which the 1st outflow port 171 was formed and the circuit board 16 was accommodated in the inside. An opening 151 is formed in the lower frame 15 between the rear side of the top plate 2 and the side wall 132 of the rear frame 13 in a plan view. The opening 151 of the lower frame 15 in the plan view is formed on the substrate case. It is formed at a position where it does not overlap the 17 first outlets 171 or the circuit board 16. For this reason, even if the liquid flows into the first exhaust air passage 20 from the first exhaust port 14 and the liquid drops from the opening 151, the infiltrated liquid or the like hardly enters the substrate case 17, and the circuit It is difficult for the liquid to contact the substrate 16. For this reason, it is possible to suppress failure and damage caused by immersion of liquid or the like in the components mounted on the circuit board 16.

  Moreover, in this Embodiment, it provided along the edge of the opening 151 of the lower frame 15, and was provided with the draining part 152 which protrudes below. The liquid flowing on the upper surface of the lower frame 15 drops along the draining portion 152 and is difficult to be transmitted to the back surface of the lower frame 15. For this reason, it is suppressed that the liquid drops on various places in the main body housing 1 along the back surface of the lower frame 15, and the failure and damage due to the liquid coming into contact with the components mounted in the main body housing 1 are suppressed. And has the effect of improving the quality and reliability of the product. Further, since the liquid is dripped through the draining portion 152, the position where the liquid is dripped into the main body housing 1 can be controlled.

  Further, in the present embodiment, a drain outlet 19 is formed on the bottom surface of the main housing 1, and at least a part of the drain outlet 19 overlaps the opening 151 or the draining portion 152 of the lower frame 15 in plan view. In the position. For this reason, even if a liquid dripped from the opening 151 or the draining part 152, the dripped liquid is easy to be quickly discharged | emitted from the drain outlet 19 arrange | positioned below. For this reason, failure and damage due to the liquid coming into contact with the components mounted in the main body housing 1 are suppressed, and there is an effect of improving the quality and reliability of the product.

For this reason, the rear frame 13 is supported by the lower frame 15 from below, and even if a cooking utensil such as a pan is placed on the rear frame 13, the rear frame 13 is inclined and deformed. The appearance quality can be improved by suppressing the decrease. Further, by suppressing the inclination and deformation of the rear frame 13, the cross-sectional area of the first exhaust air passage 20 formed between the rear frame 13 and the lower frame 15 decreases, the pressure loss increases, and the exhaust flow rate increases. There is an effect of suppressing product failure due to a decrease in the predetermined cooling effect. In the present embodiment, the first engaging portion 133 is engaged with the first shielding portion 153. However, the first engaging portion 133 is detachably engaged separately from the first shielding portion 153. The engaging portion may be provided on the lower frame 15. Further, the pair of engaging portions provided on the rear frame 13 and the lower frame 15 is provided at a position farther from the top plate 2 than the opening 151 of the lower frame 15, so that a load is applied on the rear frame 13. The effect of suppressing the inclination and deformation of the frame 13 can be enhanced.

  Further, in the present embodiment, the second shielding portion 154 is provided at a position facing the first exhaust port 14 across the opening 151 of the lower frame 15, and the second shielding portion 154 is provided on the rear side of the top plate 2. The shape extends along and protrudes upward. For this reason, even if liquid or foreign matter or the like enters the cooking device 100 from the first exhaust port 14, the liquid or foreign matter or the like is blocked by the second shielding portion 154, and the liquid or foreign matter or the like is blocked by the opening 151 of the lower frame 15. It can suppress falling into the main body housing | casing 1 from other than. For this reason, failure and damage due to liquid coming into contact with components mounted in the main body housing 1 are suppressed. In addition, there is an effect of suppressing damage to the top plate 2 due to foreign matter coming into contact with the end of the rear side of the top plate 2. In addition, when providing both the 1st shielding part 153 and the 2nd shielding part 154, by providing the upper end part of the 2nd shielding part 154 in a position higher than the upper end part of the 1st shielding part 153, liquid or The effect of suppressing the entry of foreign matter can be enhanced.

  Further, the rear frame 13 of the present embodiment includes a second engagement portion 134 that is detachably engaged with the second shielding portion 154 of the lower frame 15. For this reason, the tolerance with respect to the inclination and deformation | transformation of the rear frame 13 increases, and the designability and appearance quality can be improved. Further, the cross-sectional area of the first exhaust air passage 20 formed between the rear frame 13 and the lower frame 15 decreases, the pressure loss increases, the exhaust flow rate decreases, and a predetermined cooling effect cannot be obtained. It has the effect of suppressing product failures.

  In the present embodiment, the first engaging portion 133, the second engaging portion 134, the first shielding portion 153, and the second shielding portion 154 extend parallel to each other along the rear side of the top plate 2. It is a configuration. For this reason, by sliding the rear frame 13 along the rear side of the top plate 2, it can be attached to and detached from the lower frame 15, and there is an effect of improving the cleaning performance and the maintenance performance.

  In addition, the heating cooker 100 of the present embodiment includes a heating coil unit 7 in the main body casing 1, and at least a part of the air inlet 6 of the main body casing 1 is more of the top plate 2 than the heating coil unit 7. It was arranged at a position close to the front side, which is the side facing the rear side. For this reason, an air passage extending from the front intake port 6 to the rear first exhaust port 14 of the cooking device 100 is formed in the cooking device 100. Accordingly, the cooling air flows substantially linearly from the lower front side of the main body casing 1 to the first exhaust port 14 on the rear side, and the cooling efficiency is increased because there is little pressure loss due to bending of the cooling air passage. Moreover, since pressure loss is suppressed, the load of the air blower 8 can be reduced and a low-noise heating cooker can be obtained.

  In the present embodiment, the top plate 2 is rectangular in a plan view, and the front frame 10, the left frame 11, and the right frame that integrally surround the front side, the left side, and the right side excluding the rear side of the top plate 2. 12 was provided.

  A collecting channel 22 is provided below the upper wall 111 of the left frame 11 between a first side wall 112 and a second side wall 113 provided in parallel to each other. The collective flow path 22 is a flow path in which the downstream ends of the plurality of flow paths 23 communicate with each other (see FIG. 19), and the exhaust flow flowing through each flow path 23 merges in the collective flow path 22 and the second exhaust port 21. It flows toward.

  Furthermore, in the present embodiment, the third shielding part 156 of the lower frame 15 is disposed in the collecting flow path 22, and the upper end of the third shielding part 156 is at a position lower than the upper end of the collecting flow path 22. . The third shielding part 156 also functions as a wind guide wall that guides the exhaust flow upward, and the exhaust from each flow path 23 merges inside the third shielding part 156 of the collecting flow path 22, and the third shielding part After being guided by 156 and moving upward and exceeding the third shielding part 156, it flows out from the second exhaust port 21 located at a position lower than the upper end of the third shielding part 156.

  The second outlet 172, the flow path 23, and the second exhaust port 21 provided on the upper surface of the substrate case 17 are preferably arranged on substantially the same straight line (arranged on the same cross section) in plan perspective. By doing in this way, when the heating cooker 100 is viewed in plan, a substantially straight exhaust path extending from the second outlet 172 to the second exhaust port 21 is formed, so that pressure loss can be suppressed and exhausted. . For this reason, while being able to reduce the load of the air blower 8 and reducing power consumption, it has the effect of reducing the noise of the heating cooker 100.

  An end portion on the inner side of the flat plate surface of the lower frame 15 is disposed inside the main body housing 1, and a plate-like draining portion 158 protruding downward is provided at this end portion. For this reason, even if the liquid that has entered from the second exhaust port 21 flows through the lower frame 15, the liquid is guided to the draining portion 158 and dripped. For this reason, in the case where a part such as the circuit board 16 that is desired to avoid contact with the liquid is disposed below the draining portion 158, the circuit board 16 or the like is covered with the substrate case 17 or the like so that the liquid is It is possible to suppress contact with 16 or the like. In addition, by providing the drain port 19 below the draining portion 158, the liquid or the like dripped from the draining portion 158 is easily drained from the drain port 19, so that it can be prevented from staying in the main body housing 1. For this reason, the contact of the liquid with the circuit board 16 etc. in the main body housing | casing 1 can be suppressed, and product quality can be improved.

  Further, the first side wall 112 constituting the outer side wall of the left frame 11 also functions as a drainer. The liquid flowing on the left frame 11 flows and drops along the surface of the first side wall 112 and is difficult to be transmitted to the back side of the left frame 11, so that the liquid is prevented from entering the cooking device 100. be able to.

  The cooking device 100 according to the present embodiment is provided with a left frame 11 provided on the top plate 2 along the left side of the top plate 2 and under the top plate 2 along the left side of the top plate 2. The lower frame 15 and a plurality of support portions 157 provided between the lower surface of the top plate 2 and the lower frame 15 and in contact with the lower surface of the top plate 2 were provided. And the 2nd exhaust port 21 is formed in the clearance gap between the lower end part of the 1st side wall 112 of the left frame 11, and the kitchen top plate 201, and one end communicates in the main body housing | casing 1 between the adjacent support parts 157. At the other end, a flow path 23 communicating with the second exhaust port 21 is formed. In addition to the first exhaust port 14 formed under the rear frame 13, the exhaust in the main body housing 1 is also performed from the second exhaust port 21 formed under the left frame 11. The hot air can be exhausted more quickly and smoothly. For this reason, the damage and deterioration of the components due to the temperature rise in the main body housing 1 can be suppressed, and since the load on the blower 8 is reduced, the noise and power consumption of the blower 8 are also reduced.

  Moreover, in this Embodiment, it has the some support part 157 which supports the top plate 2 from the downward direction, and the support part 157 is the kitchen top plate 201 in planar view in the state in which the heating cooker 100 was installed in the kitchen cabinet 200. It is provided in the position which overlaps. With such a configuration, the top plate 2 is supported by the kitchen top plate 201 via the plurality of support portions 157. Since the kitchen top plate 201 indirectly supports the top plate 2 via the plurality of support portions 157, the load applied to the top plate 2 is dispersed, and damage to the top plate 2 due to the load can be reduced. Further, the left and right parts of the top plate 2 are arranged on the kitchen top plate 201, and the width of the left and right of the top plate 2 is larger than the width dimension of the storage portion 202, so that the space for cooking work is expanded. The workability of cooking increases.

  In the present embodiment, the collective flow path 22 that is provided between the second exhaust port 21 and the plurality of flow paths 23 and communicates with the downstream ends of the plurality of flow paths 23 is provided. For this reason, the temperature and the wind speed of the exhaust gas flowing through each of the plurality of flow paths 23 can be made uniform in the collective flow path 22, and then exhausted from the second exhaust port 21. The temperature and wind speed of the exhaust gas flowing through each flow path 23 vary depending on the arrangement of the flow paths 23. For example, when the high-temperature exhaust flow from the flow path 23 through which the exhaust flow that has passed through the vicinity of the high-temperature heat generating component flows directly outside, However, in this embodiment, the high-temperature exhaust flow is mixed with other exhaust flows in the collective flow path 22 to be cooled down, and then flows out through the second exhaust port 21. Can reduce excessive discomfort. The collecting flow path 22 may be disposed at a position that does not overlap the top plate 2 in plan view. By doing in this way, since the capacity | capacitance of the collection flow path 22 can be enlarged, the exhaust flow from each flow path 23 is mixed better, and the effect of equalizing the temperature and wind speed of an exhaust flow increases. In addition, the flow passage cross-sectional area of the collective flow passage 22 is enlarged, which has an effect of reducing pressure loss.

  Further, in the present embodiment, the collective flow path 22 includes a third shielding portion 156 that is a wall extending along the left side of the top plate 2 and extending vertically, and the upper end of the collective flow path 22 is It is at a position higher than the upper end of the support portion 157. For this reason, the 3rd shielding part 156 functions as a baffle plate of the exhaust in the up-and-down direction, and the channel which goes up once and falls is formed in collective channel 22 (refer to Drawing 22). Therefore, the flow path length of the collective flow path 22 is longer than that in the case where the third shielding portion 156 is not provided, and stirring of the exhaust flow from each flow path 23 in the collective flow path 22 is promoted, and the second exhaust port 21. The temperature and wind speed of the exhaust stream from the air are made more uniform. Further, when the collecting channel 22 is viewed in a vertical cross section parallel to the exhaust flow, it has an inverted U-shaped labyrinth shape, and the invasion of pests from the second exhaust port 21 into the main body housing 1 is suppressed.

  The heating cooker 100 according to the present embodiment includes the blower 8 and the substrate case 17 that has the second outlet 172 and forms an air passage through which the wind from the blower 8 flows. At least a part of the outlet 172 and at least a part of the flow path 23 are arranged on the same straight line. Since the substantially straight exhaust path from the second outlet 172 to the flow path 23 is formed in a plan view, exhaust can be performed with little pressure loss. For this reason, while being able to reduce the load of the air blower 8 and reducing power consumption, there exists an effect which reduces the noise of the heating cooker 100.

  The lower frame 15 of the present embodiment includes a draining portion 158 that is disposed inside the main body housing 1 and protrudes downward. For this reason, since the liquid flowing on the lower frame 15 is guided to the draining portion 158 and dripped, the dropping position of the liquid into the main body housing 1 can be controlled, and the circuit into the main body housing 1 can be controlled. Liquid contact with the substrate 16 and the like can be suppressed.

  A drain outlet 19 is provided below the draining portion 158 on the bottom surface of the main body housing 1 of the present embodiment. For this reason, the liquid dripped from the draining part 158 is easily discharged outside from the drain port 19 without staying in the main body housing 1. Therefore, it is possible to suppress the contact of the liquid with the components in the main body housing 1 such as the circuit board 16.

  The heating cooker 100 according to the present embodiment is provided on the front side of the top plate 2 and includes an operation unit 4 that receives an operation input. The second exhaust ports 21 are provided on the left side and the right side of the main body housing 1. .

More specifically, a shield 114 that is longer than the first side wall 112 is provided on the front side of the first side wall 112 of the left frame 11 that forms the second exhaust port 21. The second exhaust port 21 is not formed at a position overlapping the operation unit 4 in a side view. For this reason, it becomes difficult for the user who operates the operation unit 4 to come into contact with the exhaust flow, and the user's discomfort due to the contact with the exhaust flow is reduced, thereby improving the cooking work environment.

  In the heating cooker 100 of the present embodiment, the air inlet 6 is formed on the front wall and the bottom surface of the main body housing 1. A first exhaust port 14 is provided on the rear side of the main body housing 1, and second exhaust ports 21 are provided on the right and left sides of the main body housing 1. For this reason, in the heating cooker 100, a simple air flow with less bending of the air sucked from the front toward the left and right and the back is formed, and the pressure loss can be reduced. Further, by exhausting the air in the left and right and rear sides, the wind speed of the exhaust from the first exhaust port 14 and the second exhaust port 21 is reduced, and the pressure loss is further reduced. Moreover, since the wind speed of exhaust gas falls, the user's discomfort due to the exhaust coming into contact with the user can be reduced, and the cooking work environment is improved.
