Description

  The present invention relates to an induction heating cooker.

  Conventionally, this type of induction heating cooker has a configuration that prevents water entering from the exhaust port of cooling air from flowing into the main body.

  FIG. 7 shows an overall configuration diagram of a conventional induction heating cooker. As shown in FIG. 7, the main body 1, the top plate 2 on which the cooking utensils arranged on the top surface of the main body 1 are placed, the frame 3 for holding the top plate 2, and the lower side of the top plate 2 Left and right heating coils 4a and 4b, a control board 5 for controlling heating, a board cover 6 for holding the heating coil 4 installed above the control board 5, the front of the main body 1 and below the heating coil 4a Are provided on the top surface behind the main body 1 and the cooling fan 7 for cooling the heating coil 4 and the control board 5 provided on the front side, the intake port 8 provided in front of the main body 1 for supplying cooling air. A standing wall 10 is provided on the substrate cover 6, which includes left and right exhaust ports 9 a and 9 b that exhaust cooling air from the heating coil 4 and the control substrate 5, and prevents water entering from the exhaust port 9 from flowing into the main body. ing.

  However, in the above configuration, water intrusion into the main body from the exhaust port 9 can be prevented, but efficient exhaust of the cooling air from the heating coil 4a is hindered. As a result, most of the cooling air from the heating coil 4a is prevented. There was a problem in cooling efficiency because the air was exhausted to the exhaust port 9b disposed behind the heating coil 4b.

  Some have both cooling efficiency and prevention of water intrusion from the exhaust port (for example, see Patent Document 1).

  FIG. 8 shows a conventional built-in induction heating cooker described in Patent Document 1. As shown in FIG. As shown in FIG. 8, a main body 1, an exhaust port 9 provided on the main body 1 and positioned on the upper surface of the sink 11, and an upright wall 10 a perpendicular to the lower wall 1 a of the inner position of the outer wall facing the exhaust port 9, Further, a standing wall 10b perpendicular to the top wall 1b provided adjacent to the main body inner side lower wall 1a is provided to constitute a box 12 having a certain volume.

  With the above configuration, even if the user spills the water that has entered the pan or the like in the direction of the back wall 11a of the sink 11, and tries to enter the exhaust port 9 by its splash, the standing wall 10a prevents it, Even when a part of the inundation jumps over the upper end of the standing wall 10a, this is blocked by the standing wall 10b to prevent direct water impingement on the control board 5 provided in the main body, and the invaded water is further boxed. 12 prevents the water from adhering to the back surface of the control board 5 due to inflow, and if it overflows into the main body in a large amount, it is provided in the main body before the allowable value stored in the box portion 12 is exceeded. It is possible to prevent the water from adhering to the back surface of the control board 5 and the like by allowing the opening to escape into the sink.

  However, in the above configuration, the wall for preventing water intrusion is provided on the outer shell of the main body, and the top portion cannot be made thin.

  In addition, there is a type in which the top portion is made thin and water intrusion and cooling efficiency are compatible (for example, see Patent Document 2).

  FIG. 9 shows a conventional built-in heating cooker described in Patent Document 2. As shown in FIG. A top plate 2, a support 14 that supports the top plate 2 from below, a frame 3 that covers an end surface portion of the top plate 2, and a main body shell 1, and an exhaust port 9 </ b> A on the side wall of the support 14. In addition, the structure in which the exhaust port 9B is also provided in the frame 3 at a position corresponding to the exhaust port 9A can achieve both overflow and cooling performance with a thin top configuration and keep the space of the top plate 2 wide. .

  However, even with the above-described configuration, the unevenness between the sink and the top plate is large, and in the case of an induction heating cooker such as a stationary one, installation size restrictions are large and it is difficult to attach an exhaust configuration outside the main body. In addition, when the top surface of the main body has an exhaust port, it is no longer necessary to stand a wall in order to ensure cooling performance.

JP 11-354263 A JP 2005-265209 A

  However, in the conventional configuration, water intrusion into the main body from the exhaust port can be prevented, but cooling efficiency is lowered by hindering efficient exhaust of the cooling air from the heating coil, and the top portion is made thin. Since it cannot be performed, the unevenness between the sink and the top plate becomes large, and there are problems that the installation dimension is large and it is difficult to attach the exhaust structure outside the outer shell of the main body.

  The present invention solves the above-mentioned conventional problems, and in a limited installation state, without impairing the function of preventing failure and tracking due to water wetting of internal parts due to water intrusion into the main body, cooling efficiency performance An object of the present invention is to provide a highly reliable induction heating cooker that ensures both cooling performance and overflowing performance.

  In order to solve the above-described conventional problems, an induction heating cooker according to the present invention has a box-shaped main body having an opening on the upper surface and constituting an outer shell, and covers the upper surface of the main body, and places the cooking container to be heated. A top plate, a frame for holding the top plate, a heating coil that is located below the top plate and heats the heated cooking container, a control board that controls heating, and a heating board that is installed above the control board, A board cover for holding, a cooling fan for cooling the heating coil and the control board provided in front of the main body, an air inlet provided in front of the main body for supplying cooling air, and a rear top surface of the main body The heating coil and the exhaust hole for exhausting the cooling air of the control board, the first wall provided perpendicularly in the left-right direction, and the end of the first wall are provided in the front-rear direction with a predetermined interval. A side wall and from the side wall to the inside of the first wall end. And a submergence barrier comprising a second wall vertically opposed in the left-right direction at a predetermined interval behind the first wall, and the submersion barrier at a position lower than the exhaust port side on the rear side of the substrate cover and the upper surface of the substrate cover. A mounting surface for mounting the water is formed, and a flooded barrier is arranged on the mounting surface in front of the exhaust port.

  Thereby, even when water enters from the exhaust port provided on the top surface of the main body, it is possible to prevent the inflow into the main body by the first wall and the second wall provided on the inundation barrier, In the unlikely event that a large amount of water is poured from the top of the main unit and enters the inundation barrier, the inundation barrier is installed at a position lower than the upper surface of the substrate cover on which the heating coil is placed. It takes a considerable amount of time to overflow and reach the upper surface of the substrate cover.

  Therefore, it is possible to further enhance the effect of preventing water from entering the heating coil side through which a large current flows. In addition, a side wall formed in the front-rear direction with a predetermined distance from the first wall and its end, and a predetermined distance from the side wall to the inner side of the first wall end and behind the first wall. With the construction of the submergence barrier that forms the second wall that is vertically opposed in the left-right direction, it is possible to secure an exhaust induction path for the cooling air of the heating coil.

  The induction heating cooker of the present invention prevents water from flowing into the main body by the inundation barrier even when water enters from the exhaust port provided on the top surface of the main body, and a large amount of water is poured. Even when the water barrier is overcome, water is prevented from entering the large current portion or the main body, so that it is possible to prevent malfunctions, electric shocks, and tracking due to wetness of the internal components and the charging portion. In addition, since the construction of the inundation barrier itself secures the exhaust induction path, it is possible to increase the cooling efficiency and provide a highly reliable induction heating cooker that achieves both cooling performance and overflow performance. .

  A first invention has a box-shaped main body having an opening on the upper surface and constituting an outer shell, a top plate that covers the upper surface of the main body and on which a cooking container to be heated is placed, and for holding the top plate A frame, a heating coil that is positioned below the top plate and that heats the heated cooking container, a control board that controls heating, and a substrate cover that is installed above the control board and holds the heating coil; A cooling fan for cooling the heating coil and the control board provided in front of the main body, an air inlet provided in front of the main body for supplying cooling air, Exhaust port for exhausting cooling air from the heating coil and the control board, a first wall provided vertically in the left-right direction, and a side wall formed in the front-rear direction with a predetermined distance from the end of the first wall And the inner side of the side wall than the first wall end. And a submergence barrier wall comprising a second wall facing the left-right direction at a predetermined interval behind the first wall, and at a position lower than the upper surface of the substrate cover on the exhaust port side behind the substrate cover In addition, an attachment surface for attaching the inundation barrier is formed, and the infiltration wall is disposed on the attachment surface in front of the exhaust port.

  As a result, even when water enters from an exhaust port provided on the top surface of the main body, the first wall and the second wall of the inundation barrier prevent water from flowing into the main body and a large amount of water. Even if it is poured, the water first accumulates in the flooded barrier, and the flooded barrier is attached at a position lower than the upper surface of the substrate cover on which the heating coil is placed. It takes considerable time for the water to overflow and reach the top surface of the substrate cover. Therefore, because it has a configuration that can further enhance the effect of preventing water from entering the large current part such as a heating coil and the main body, it can prevent failure, electric shock, and tracking due to water wetting of internal parts and charging parts. it can.

  In addition, a side wall formed in the front-rear direction with a predetermined distance from the first wall and its end, and a predetermined distance from the side wall to the inner side of the first wall end and behind the first wall. With the construction of the inundation barrier that forms the second wall that is vertically opposed in the left-right direction, the exhaust air guide passage for the cooling air of the heating coil is secured, so that the cooling air exhaust of the heating coil is not hindered Therefore, the cooling efficiency can be increased. Therefore, it is possible to provide a highly reliable induction heating cooker that achieves both cooling performance and overflow performance.

  In particular, the second invention is provided with a water drainage hole provided on the bottom surface of the main body of the first invention for draining water to the outside of the main body, and formed at a position lower than the upper surface of the substrate cover on the rear exhaust port side of the substrate cover. Even when a large amount of water has entered from the exhaust port provided on the top surface of the main body, the main body side is placed on the main body side by the second wall of the inundation barrier because the end of the surface faces downward and the inclined surface is formed. Since water does not enter and does not collect on the bottom of the flood barrier and the board cover, it falls to the bottom of the main unit, and water escapes from the drain hole formed on the bottom of the main unit to the outside of the main unit. Therefore, it is possible to prevent an electric shock or a failure.

  The third aspect of the invention is particularly an inclined surface formed on the substrate cover rear exhaust port side of the second invention, with the end of the infiltration wall mounting surface formed at a position lower than the upper surface of the substrate cover facing downward. By forming at least one groove on the bottom, when water falls on the bottom surface of the main body, it passes through the groove with the vector directed downward. More water can escape.

  According to a fourth aspect of the present invention, in particular, a gap is provided between the inundation barrier according to the first aspect of the invention and the stepped wall of the substrate cover that extends in a vertical direction from the attachment surface of the inundation barrier and forms the step. Due to the installation configuration, if the water overflows the first wall of the inundation barrier and overflows into the inside of the main body, it does not immediately flow out to the upper surface of the substrate cover, but flows into the gap once. For this reason, it takes a considerable amount of water and water injection speed in order to overflow the upper surface of the substrate cover over the step, so that it is possible to obtain a configuration rich in water overflow.

  According to a fifth aspect of the present invention, in particular, a flange is provided on the inundation barrier of the first invention, and a hole for fixing the inundation barrier to the substrate cover with a screw and a hole for positioning are formed in the flange. Since the screw holes and positioning ribs are also formed on the cover, and they are attached to each other, there is positioning for attachment, so that the assembly is good and the screws can be firmly fixed by attaching them with screws. Therefore, it is possible to reduce the floating between the water barrier and the substrate cover, and to prevent water from entering the inside.

  The sixth invention is the fifth invention, in particular, in the fifth invention, provided with a side-falling prevention metal fitting for preventing the side wall of the main body from falling sideways, and the screw holes for attaching each other formed on the water-proofing wall and the substrate cover are Since the screw hole is also used as a screw hole for attaching the side-falling prevention metal fitting, it is possible to realize the fixing of the flood barrier and the substrate cover and the fixing of the board cover and the side-fall prevention metal fitting with a small number of screws.

  In the seventh invention, in particular, at least one fitting convex portion is provided on the inundation barrier or the substrate cover of the first invention, and the fitting concave portion is formed on the other to form a fitting concave portion to be engaged, By adopting a configuration in which the flood barrier and the substrate cover are attached, it is possible to attach without the screws, and the cost can be reduced.

  In the eighth aspect of the invention, in particular, by providing a rib having a height lower than that of the flood barrier opening for exhausting the air that has cooled the heating coil on the upper surface exhaust port side of the substrate cover of the first aspect of the invention. Even when water rides on the upper surface of the substrate cover, the water cannot enter the heating coil side unless it gets over the ribs. Therefore, the effect of preventing the water from entering can be further increased as compared with the case without the ribs. Moreover, since the rib is lower than the height of the flooded barrier opening for exhausting the cooling air, the exhaust is not hindered and the cooling efficiency can be ensured.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

FIG. 1 shows a cross-sectional view of the induction heating cooker in the first embodiment of the present invention, and FIG. 2 is a partially enlarged view of the induction heating cooker in the first embodiment of the present invention. is there.

  The main body 1 bends metal into a box shape, has an opening on the upper side, and installs the top plate 2 on which the cooked utensils arranged so as to cover the upper opening of the main body 1 and the top plate 2 are installed on the main body 1. For this purpose, it is composed of a metal frame 3 having holes for supporting and connecting the top plate 2.

  In addition, the induction heating cooker of the present invention includes a heating coil 4 for heating a cooked utensil provided below the top plate 2, and a control board 5 that controls heating is provided in the main body 1 with a board holding member. 15, a substrate cover 6 is installed above the control substrate 5 and holds the heating coil 4.

  A cooling fan 7 for cooling the heating coil 4 and the control board 5 provided in front of the main body 1 and below the heating coil 4 is provided, and cooling air is sucked from an intake port 8 provided in front of the main body. After the heating coil 4 and the control board 5 are cooled, the structure is exhausted from an exhaust port 9 provided on the top surface behind the main body.

  Further, the exhaust cover 9 side of the substrate cover 6 is made lower than the upper surface 20 of the substrate cover to form a step, forming a step wall 21 and an attachment surface 13, and further attaching the inclined surface 22 with the end of the attachment surface 13 facing downward. The inclined surface 22 is formed with at least one groove 23 (FIG. 2).

  Further, a drain hole 24 is provided on the bottom surface of the main body 1 for allowing water that has entered the main body to escape outside the main body.

  FIG. 3 is a configuration diagram of a flooded barrier of the induction heating cooker according to the first embodiment of the present invention.

  Here, as shown in FIG. 3, the inundation barrier 16 (FIG. 1) is provided perpendicular to the left-right direction, and is a first wall having a height that does not contact the top plate 2 and the frame 3. 17 and the end of the first wall 17 are formed in the front-rear direction at a predetermined interval, and the side wall 18 has the same height as the first wall 17, and the inner side from the side wall 18 to the end of the first wall 17 As a result, a second wall 19 is formed on the rear side of the first wall 17 so as to be vertically opposed in the left-right direction with a predetermined interval.

  Further, an air guide opening 25 is formed so as to guide the exhaust of the cooling air from the heating coil 4 and the like provided so as to face the first wall 17.

  As shown in FIG. 1, the inundation barrier 16 has a step wall 21 and a gap 33 on the mounting surface 13 formed on the substrate cover 6, and a positioning rib 28 a formed on the substrate cover 6 and a bottom surface of the inundation barrier. Positioned by positioning rib holes 28b formed in the provided water-permeable barrier flange 26 and fixed by screws by screw holes 27a formed in the substrate cover 6 and screw holes 27b formed in the water-permeable barrier bottom flange. It is said.

  In addition, the structure which attaches the flooding barrier 16 to the board | substrate cover 6 in the attachment surface 13 may not be sufficient.

  With the above configuration, as shown in FIG. 1, the inundation barrier 16 provided on the substrate cover 6 is disposed in front of the lower side of the exhaust port 9, so that the exhaust port 9 provided on the top surface of the main body can be removed. Even when water enters, the first wall 17 and the second wall 19 of the inundation barrier 16 shown in FIG. 3 can prevent water from flowing into the main body. Even if water gets over and water enters from a predetermined distance between the first wall 17 and the side wall 18 and the water overflows from the wind guide opening 25 formed in the infiltration barrier 16 to the main body side, Since there is a gap 33 between the step wall 21 formed by the step of the substrate cover 6, water once accumulates in the gap 33 before entering the main body.

  Even when the gap 33 overflows, it takes a considerable time for water to enter the upper surface 20 of the substrate cover due to the provision of the step.

  In the meantime, the inclined surface 22 formed behind the substrate cover 6 and the groove 23 formed in the inclined surface 22 are placed on the bottom surface of the main body 1 to form a vector for dropping water downward. Further, the water can be discharged out of the main body through the drain hole 24, and the accumulated water does not enter the upper surface 20 of the substrate cover holding the heating coil 4 through which a large current flows.

  At this time, since the control board 5 is protected from water by the board holding member 15, it is possible to prevent failure, electric shock, and tracking due to wetness of the internal parts of the main body and the charging unit, and a large amount of water is poured into the main body. Even in the case of peeling, it can be made highly safe.

  Further, the side wall 18 formed in the front-rear direction with a predetermined distance from the first wall 17 and its end, and the rear side of the first wall 17 extends from the side wall 18 to the inner side of the end of the first wall 17. A second wall 19 that is vertically opposed to the left and right direction is formed at a predetermined interval, and the construction of the inundation barrier 16 having the air guide opening 25 for exhausting the cooling air completely forms the wall. In addition, since the exhaust air guide path for cooling air is secured, the exhaust air is not hindered, so that the cooling efficiency can be improved.

  Further, a screw hole 27b for fixing the submergence barrier 16 to the board cover 6 with a screw and a rib hole 28b for positioning are formed on the submergence barrier flange 26 formed on the bottom surface of the submergence barrier 16. By forming the screw holes 27a and the positioning ribs 28a and attaching them to each other, there is positioning for attachment, so that the assemblability is improved.

  Moreover, since it can fix firmly by attaching with a bis | screw, the floating of the infiltration barrier 16 and the board | substrate cover 6 can be made small, and the inundation to the inside can be prevented more.

  Note that the positioning rib 28 a may be provided in the flooded barrier 16 and the positioning rib hole may be provided in the substrate cover 6. In addition, the configuration for attaching the inundation barrier 16 and the substrate cover 6 may not be configured on the attachment surface 13. Therefore, the flood barrier flange 26 formed on the bottom surface of the flood barrier 16 may not be the bottom surface.

  As described above, it is possible to provide a highly reliable induction heating cooker that achieves both cooling performance and overflow performance.

(Embodiment 2)
FIG. 4 is a configuration diagram of a flooded barrier of the induction heating cooker according to the second embodiment of the present invention.

  In the present embodiment, the side wall fall prevention metal fitting 29 for preventing the side wall of the main body 1 from falling down is provided, and the screw hole 27a and the screw hole 27b for attaching the flood prevention wall 16 and the substrate cover 6 to each other are provided. The difference is that the screw hole 27c for attaching the side-falling prevention metal fitting 29 is also used. Others are the same as those in the first embodiment, and thus the description thereof is omitted.

  With the above-described configuration, the fixing of the flood barrier 16 and the substrate cover 6 and the fixing of the substrate cover 6 and the side-fall prevention metal fitting 29 can be realized with a small number of screws, so that the number of assembly steps can be reduced and the number of screws can be reduced. Since it can be reduced, it can contribute to cost reduction.

(Embodiment 3)
FIG. 5 is a configuration diagram of a flooded barrier of the induction heating cooker according to the third embodiment of the present invention.

  In the present embodiment, at least one fitting convex portion 30 is provided on the inundation barrier 16 or the substrate cover 6 of the first embodiment, and the fitting concave portion 31 into which the fitting convex portion 30 is inserted and engaged is provided on the other side. It is different in that it is formed and the infiltration barrier 16 and the substrate cover 6 are attached. Others are the same as those in the first embodiment, and thus the description thereof is omitted.

  By adopting the above-described configuration, it is possible to attach without a screw and the attachment becomes easy, so that the number of assembling steps and cost can be reduced. In addition, the fitting convex part 30 and the fitting recessed part 31 may exist in any of the water immersion barrier 16 and the board | substrate cover 6. FIG. Further, the mounting configuration may not be on the mounting surface 13.

(Embodiment 4)
FIG. 6 is a sectional view of an induction heating cooker in the fourth embodiment of the present invention.

  In the present embodiment, ribs having a height lower than the height of the air guide opening 25 provided in the flood barrier 16 for exhausting the wind that has cooled the heating coil 4 on the substrate cover upper surface 20 of the first embodiment. The difference is that 32 is provided. Others are the same as those in the first embodiment, and thus the description thereof is omitted.

  With the above configuration, even if water overflows from the gap 33 between the inundation barrier 16 and the step wall 21 and rides on the upper surface 20 of the substrate cover, if the water does not get over the rib 32, the water will move to the heating coil 4 side. Therefore, the effect of preventing the ingress of water can be further increased as compared with the case where there is no rib.

  Further, since the rib 32 is lower than the height of the air guide opening 25 provided in the inundation barrier 16 for exhausting the cooling air, the exhaust air is not hindered and the cooling efficiency can be ensured. It is possible to provide a highly reliable induction heating cooker that balances performance.

  As described above, the induction heating cooker according to the present invention prevents water from flowing into the main body by the inundation barrier even when water enters from the exhaust port provided on the top surface of the main body. It can prevent malfunctions, electric shocks, and tracking due to water getting wet in the live parts, and the construction of the inundation barrier itself secures the exhaust guiding path, so that the cooling efficiency can be improved, and the cooling performance and overflow performance Since it is possible to achieve both, it is effective for the use of cooking appliances.
