  However, in the conventional induction heating cooker, since the left part heating coil 221 and the right part heating coil 222 are arranged in the heating coil accommodation space 231 protruding from the accommodation part 208 to the upper part of the top plate 220, the top plate 201. There is a possibility that a liquid such as water existing on the upper part or the upper part of the top plate 220 may enter the lower part of the top plate 201 and come into contact with the left part heating coil 221 and the right part heating coil 222.

  When the liquid contacts the left heating coil 221 and the right heating coil 222, the left heating coil 221 and the right heating coil 222, which are high potential parts, can cause dielectric breakdown and generate a sufficient magnetic field. Therefore, there is a fear that the object to be heated cannot be heated.

  Further, an inverter disposed in the accommodating portion 208 through which the liquid adhering to the left portion heating coil 221 and the right portion heating coil 222 is transmitted through a wiring electrically connected to the left portion heating coil 221 and the right portion heating coil 222. When reaching the device 205, it causes a breakdown of the electrical components constituting the inverter device 205, insulation deterioration, and a decrease in the life of the electrical components due to corrosion, and depending on the situation, the induction heating cooker may fail. Had.

  The present invention solves the above-mentioned conventional problems, and the heating body including the left part heating coil 221 and the right part heating coil 222 is placed in the heating coil accommodation space 231 protruding from the accommodation part 208 to the top of the top plate 220. It is an object of the present invention to provide a heating cooker that is safe and does not cause insulation deterioration or life reduction without causing the liquid present on the top plate 220 to come into contact with the heating body even if the layout is arranged.

  In order to solve the above-described conventional problems, a heating cooker according to the present invention includes a top plate on which a cooking container is placed, a heating body that is disposed below the top plate and that heats the cooking container, and the heating body electrically A top plate having an area exceeding the opening area of the housing portion is provided above the housing portion, and includes a circuit that is connected and supplies power, and a housing member that is disposed below the heating body and serves as an outline of the housing portion that houses the circuit and the like. When the cooking device is assembled in the cabinet of the kitchen device, at least a part of the heating body is sandwiched between the top plate and the top plate of the cabinet of the kitchen device. And at least two partition walls that do not cross each other are provided on the outer periphery of the heating body located between the top plate and the top plate of the cabinet of the kitchen apparatus. It is.

  As a result, by having the partition wall portion on the outer peripheral portion of the heating body located outside the accommodating portion, the liquid is about to enter the heating body disposed on the top plate of the cabinet of the kitchen apparatus from the peripheral portion of the top plate. Alternatively, the liquid can be blocked by the partition wall so that the liquid does not enter the heating element disposed inside the partition wall.

  Moreover, by having two partition walls, the liquid is passed to the vicinity of the containing member as a flow path of the liquid that has passed through the first partition wall that is further away from the heating body between the two partition walls.

1st invention, The top plate which mounts a cooking container, The heating body which is arrange | positioned under the top plate and heats the cooking container, The circuit which is electrically connected with the heating body and supplies electric power, A top member having an area that exceeds an opening area of the housing portion, and is disposed above the housing portion. When the cooking device is assembled in the cabinet of the kitchen device, at least a part of the heating body is sandwiched between the top plate and the top plate of the cabinet of the kitchen device. The outer peripheral portion of the heating body positioned between the top plate and the top plate of the cabinet of the kitchen apparatus is small and does not cross each other. Both a cooker having two partition walls.

  Thereby, by having a partition part in the outer peripheral part of the heating body located outside the housing part, the liquid tries to infiltrate from the peripheral part of the top plate into the heating body arranged on the top plate of the cabinet of the kitchen apparatus. Alternatively, the liquid can be blocked by the partition wall so that the liquid does not enter the heating element disposed inside the partition wall.

  In addition, by having two partition walls, as a liquid flow path that has passed through the first partition wall that is further away from the heating body between the two partition walls, to the vicinity of the housing member Since the liquid can be guided, the height of the liquid is increased by the accumulation of the liquid, and the liquid that attempts to cross the second partition located inside the heating body can be eliminated. .

  The second invention is a cooking device in which the partition wall portion, which is the position farthest from the heating body in the first invention, is arranged below the peripheral edge portion of the top plate.

  As a result, the area outside the partition wall near the heating body and sandwiched between the top plate and the top plate of the cabinet can be used as a flow path, so that the fluid pressure is reduced due to the large fluid area. The possibility that the height of the liquid existing in the lower portion of the top plate is increased and the partition wall located near the heating body is exceeded can be further reduced.

  In a third aspect of the invention, in particular, in the first or second aspect of the invention, a support member having a surface substantially parallel to the top plate is provided on the upper peripheral edge of the housing member, and at least a part of the heating body is It is a heating cooker which arrange | positions above a support member and formed a part of said support member located in the outer peripheral part of the said heating body in the said partition part.

  Thereby, even if it is the part which protruded from the accommodating part by arrange | positioning a heating body above a support member, a heating body can be hold | maintained with a support member.

  Moreover, there exists the objective made to isolate | separate with the downward direction of the supporting member which has not arrange | positioned a heating body by arrange | positioning a heating body above a supporting member. Thus, even if the liquid blocked by the partition wall passes between the upper part of the top plate of the cabinet of the kitchen apparatus and the lower part of the partition wall, the heating element disposed above the support member is prevented from coming into contact with the liquid. be able to.

  Further, by making the partition wall part integral with the support member, it is possible to simplify the mounting property of the partition wall and enhance the sealing function.

  In particular, the fourth invention is a cooking device according to the third invention, wherein a liquid path is provided on the lower surface of the support member. As a result, there are more options for the flow path of the liquid than simply reflecting the fluid that travels from the peripheral edge of the top plate to the top of the cabinet top of the kitchen apparatus to the outside of the partition wall, so the fluid pressure is reduced. By suppressing the height of the liquid from the top plate, it is possible to increase the function of preventing liquid from entering from the upper part of the partition wall.

5th invention is a heating cooker which has the convex part under the support member in 4th invention especially. Thereby, a space | gap part can be reliably formed between the top plate of the cabinet of a kitchen apparatus, and a supporting member, and the stable flow path can be ensured.

  In a sixth aspect of the present invention, in particular, in any one of the first to fifth aspects of the invention, the end of the partition wall is a heating cooker positioned closer to the housing portion than the upper peripheral edge of the housing member. As a result, the liquid on the top plate is heated even if it reaches the upper peripheral edge of the storage member because the support member has a partition wall no matter which direction the liquid is transmitted from any direction on the top plate of the cabinet of the kitchen device. There can be no flow path that directly hits the body.

  Also, since the liquid reaching the vicinity of the upper peripheral edge of the housing member falls downward from the opening of the cabinet of the kitchen apparatus incorporating the heating cooker, the liquid swirls from the end of the partition wall and enters the liquid. It is possible to prevent the route from coming.

  In a seventh aspect of the invention, in particular, in any one of the third to sixth aspects of the invention, the support member is a heating cooker that is bent downward on the side of the accommodating portion with respect to the upper peripheral edge of the accommodating member. As a result, the liquid flowing on the lower surface of the support member is converted into a downward flow path at the bent portion, so that the possibility that the liquid swirls above the support member can be extremely reduced.

  In addition, since the support member exists below the support surface of the heating body by bending downward, the support member is attached to the storage member forming the storage portion or the storage object stored in the storage portion. The support member can be fixed at a desired position.

  According to an eighth invention, in particular, in any one of the third to seventh inventions, the support member is formed as a member separate from the housing member, and is fitted into the housing member or the housing accommodated in the housing portion. Or it is a heating cooker connected by screwing or an adhesive. This makes it possible to share the heating cooker housing in which all of the heating element is housed in the housing portion and the heating cooker housing in which a part of the heating body protrudes outside the housing portion by simply attaching and detaching the support member. Therefore, two cookers with different configurations can be realized at low cost.

  In a ninth aspect of the invention, in particular, in any one of the third to seventh aspects of the invention, the support member is a heating cooker connected to the heating body by fitting, screwing, or an adhesive. This makes it possible to share the heating cooker housing in which all of the heating body is housed in the housing portion and the heating cooker housing in which a portion of the heating body protrudes outside the housing portion simply by selecting the heating body to be arranged. Therefore, two cookers with different configurations can be realized at low cost.

  In a tenth aspect of the present invention, in particular, in any one of the first to ninth aspects, the cooking member having a liquid passing means for discharging the liquid or the like that has entered the housing portion downward in the housing member located below the housing portion It is a vessel. Thereby, the liquid transmitted through the support member is not accumulated in the housing portion, and damage to the inverter device or the like disposed in the housing portion can be prevented.

  In an eleventh aspect of the invention, in particular, in any one of the third to tenth aspects of the invention, the support member is a heating cooker made of a nonmagnetic material and using the heating element as a heating coil. Thereby, the influence which a support member heats with the magnetic field which generate | occur | produced from the heating coil can be reduced, and the improvement of safety | security and the improvement of thermal efficiency that a housing | casing outer frame does not become hot can be aimed at.

  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.

(Embodiment 1)
FIG. 1A is a plan view of a kitchen apparatus including an induction heating cooker having two partition walls of the heating cooker according to the first embodiment of the present invention. Moreover, FIG.1 (B) is the sectional view on the AA line of FIG. 1 (A) of the heating cooker in the 1st Embodiment of this invention.

  As shown in FIG. 1B, the induction heating cooker in the present embodiment is provided with a flat top plate 201 made of a non-metallic member such as heat-resistant glass, and below the top plate 201. And an accommodating portion 208.

  Also, below the top plate 201, a left heating coil 221, a right heating coil 222, and a middle heating coil 223, which are heating bodies for induction heating of an object to be heated such as a pan placed on the top plate 201, are provided. Has been placed. These left part heating coil 221, right part heating coil 222, and middle part heating coil 223 are arranged so as to be substantially in contact with the back surface of the top plate 201.

  Further, a roaster 206 and an inverter device 205 are arranged in the housing portion 208.

  In the induction cooking device having the above-described configuration, as shown in FIG. 1B, the housing portion 208 is inserted into the opening 212 provided in the top plate 220 of the cabinet 209 of the kitchen apparatus, and the outer peripheral portion of the top plate 201. Is mounted on the top plate 220 to be incorporated into the kitchen apparatus.

  Moreover, the induction heating cooker of this Embodiment is the heating coil accommodation space 231 which can accommodate the left part heating coil 221 and the right part heating coil 222 between the top plate 220 and the top plate 201 of the cabinet 209 of the kitchen apparatus. A part of the left part heating coil 221 and the right part heating coil 222 are arranged in the heating coil housing space 231.

  Further, the outer peripheral portion of the left heating coil 221 and the right heating coil 222 arranged between the top plate 220 and the top plate 201 of the cabinet 209 of the kitchen apparatus is provided with an internal partition wall 303 and an internal partition wall 303. An external partition 309 is provided at a distance.

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

  As shown in FIG. 1B, when a part of the left heating coil 221 protrudes from the housing portion 208, when the induction heating cooker is incorporated in the cabinet 209 of the kitchen apparatus, the left heating coil 221 becomes the kitchen apparatus. The top plate 220 is disposed on the top.

  In the vicinity of the kitchen apparatus, for example, cooking by heating on the top plate 201 may cause spilled liquid during cooking. When there is a large amount of the boiled liquid, it can be expected that the boiled liquid flows from the periphery of the heated object to the peripheral edge of the top plate 201 and then flows out onto the top plate 220.

  In addition, there are many situations in which liquid exists on the top plate 220, for example, the vegetable moisture is transferred onto the top plate 220 by placing the washed and wet vegetables on the top plate 220. Sometimes a large amount of water is present at a stretch, such as a container with a liquid placed on a top board falling down.

  A large amount of liquid spilled on the top plate diffuses to the surroundings, but part of it also penetrates into the lower part of the top plate incorporated in the kitchen device, and this liquid is applied to the left heating coil 221, for example. The left heating coil 221 may be short-circuited or cause electric leakage, which is dangerous.

Therefore, as in the present embodiment, the external partition wall 309 serves as a bank by entering the structure having the external partition wall 309 on the outer peripheral portion of the support member 301 and tries to enter the left heating coil 221. The liquid can be shut off.

  Further, most of the blocked liquid goes around the outside of the external partition wall 309 and diffuses in the direction toward the back or the front of the cross-sectional view. However, since the height of water temporarily increases when the liquid collides with the partition wall, there is a liquid that exceeds the upper part of the external partition wall 309 when the liquid amount exceeds a certain level.

  Normally, as a countermeasure against the liquid that passes over the upper part of the external partition wall 309, a countermeasure is taken to prevent liquid such as packing from entering between the external partition wall 309 and the top plate 201.

  However, if the packing is corroded due to aging, the water stop function is weakened, and it is considered that liquid enters. In order to prevent the liquid that has passed over the external partition wall 309 from entering the heating body, the external partition wall 309 serving as the first partition wall is provided by having the internal partition wall 303 serving as the second partition wall. It is possible to realize a safe cooking device without electric shock or the like so that the liquid that has passed does not enter the heating body.

  Further, by arranging the liquid so as not to cross the external partition wall 309 and the internal partition wall 303 so that the liquid beyond the external partition wall 309 is accumulated and this time does not exceed the internal partition wall 303. By forming the space between the external partition wall portion 309 and the internal partition wall portion 303 as a flow path (in the direction of the arrow in FIG. 1A), the liquid that has passed over the external partition wall portion 309 is removed from the top plate of the cabinet 209 of the kitchen apparatus. In addition, the liquid can be guided to the opening 212 provided at the bottom, and the liquid can be discharged from the opening 212 downward to eliminate the liquid that tends to exceed the internal partition wall 303.

  Here, in a situation where a large amount of water falls instantaneously, such as spilling a container containing liquid on the top plate of the cabinet 209 of the kitchen apparatus, even if the sealing between the external partition wall 309 and the top plate 201 is poor. Since the flow width of the liquid is narrow and it becomes difficult for the fluid to flow under pressure, the flow of liquid exceeding the external partition wall 309 does not have a flow velocity or the like that exceeds the internal partition wall 303 as it is, so the main measure is left This is extremely effective as means for preventing liquid from entering the part heating coil 221 and the right part heating coil 222.

(Embodiment 2)
FIG. 2 (A) is a plan view of a kitchen apparatus provided with an induction heating cooker having two partition walls of the heating cooker according to the second embodiment of the present invention. Moreover, FIG.2 (B) is the sectional view on the AA line of FIG. 2 (A) of the heating cooker in the 2nd Embodiment of this invention.

  2A and 2B, the external partition wall 309 is different from that in FIGS. 1A and 1B in that the external partition wall 309 is disposed below the peripheral edge of the top plate 201.

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

  As shown in FIG. 2B, by arranging the outer partition wall 309 below the peripheral edge of the top plate 201, the lower part of the top plate 201 excluding the upper part of the storage part 208 and the inner side of the inner partition wall 303 is external. It becomes the flow path of the liquid which has exceeded the partition part 309.

  Therefore, since the channel area is larger than that having the external partition wall 309 near the internal partition wall 303 shown in FIG. 1A, the height of the liquid beyond the external partition wall 309 is suppressed low, The function of preventing the liquid from entering the inner partition wall 303 can be further enhanced.

  Further, from the viewpoints of design and care, the top plate 201 often has a wall portion in order to prevent the unevenness as much as possible. Therefore, by sharing the wall portion with the external partition wall portion 309, it is possible to save the trouble of newly forming the external partition wall portion 309 inside the peripheral portion of the top plate.

  At this time, the wall portion of the top plate 201 becomes a downwardly projecting partition wall portion, and the liquid partitioning ability of the external partition wall portion 309 is lower than that of the upward projecting partition wall portion, but the external partition wall portion 309 and the internal partition wall portion are reduced. 303 is wide (in the direction of the arrow in FIG. 2A), the fluid does not flow easily, and the inner partition 303 protects the left heating coil 221 and the right heating coil 222. In view of this, it is sufficient to prevent the liquid from entering the inner partition wall 303.

(Embodiment 3)
FIG. 3: is a perspective view which shows the structure of the heating coil arrange | positioned above the supporting member and supporting member of the heating cooker in the 3rd Embodiment of this invention. FIG. 4 is a partial cross-sectional view of a kitchen apparatus provided with an induction heating cooker having a support member for the heating cooker according to the third embodiment of the present invention.

  In FIG. 3, the support member 301 has a heating body mounting portion 302 on which the left portion heating coil 221 is mounted, and has an internal partition wall portion 303 around the heating body mounting portion 302.

  As shown in FIG. 4, when a part of the left heating coil 221 is configured to protrude from the storage unit 208 to the top of the top plate 220 of the cabinet 209 of the kitchen apparatus, the protruding part of the left heating coil 221 is The supporting member 301 to support is required.

  Therefore, the support member 301 shown in FIG. 3 is arranged in the positional relationship shown in FIG. 4 to support the left heating coil 221.

  As shown in FIG. 4, when a part of the left heating coil 221 protrudes from the storage unit 208, when the induction heating cooker is incorporated in the cabinet 209 of the kitchen apparatus, the left heating coil 221 is the top plate of the kitchen apparatus. 220 will be placed on top.

  In the vicinity of the kitchen apparatus, for example, cooking by heating on the top plate 201 may cause spilled liquid during cooking. When there is a large amount of the boiled liquid, it can be expected that the boiled liquid flows from the periphery of the heated object to the peripheral edge of the top plate 201 and then flows out onto the top plate 220.

  In addition, there are many situations in which liquid exists on the top plate 220, for example, the vegetable moisture is transferred onto the top plate 220 by placing the washed and wet vegetables on the top plate 220. Sometimes a large amount of water is present at a stretch, such as a container with a liquid placed on a top board falling down.

  Although a large amount of liquid spilled on the top plate diffuses to the surroundings, a part of the liquid also penetrates into the lower part of the top plate incorporated in the kitchen apparatus, and when this liquid gets on the left heating coil 221, the left part This may cause a short circuit or electric leakage of the heating coil 221 and is dangerous.

  Therefore, as in the present embodiment, by having the internal partition wall portion 303 on the outer peripheral portion of the support member 301, the internal partition wall portion 303 serves as a bank and tries to enter the left heating coil 221. The liquid can be shut off.

Further, most of the blocked liquid circulates outside the inner partition wall 303 and diffuses in the back or front direction of the cross-sectional view, or passes between the top of the top plate 220 and the support member 301, When reaching the opening 212, it drops downward.

  When the liquid diffuses to the outer periphery of the inner partition wall 303, the liquid reflects in the direction in which the liquid has entered, or travels along the outer periphery of the inner partition wall 303 and falls downward from the opening 212. Considering that if it is short, the end of the partition wall turns and liquid is applied to the left heating coil 221, the end of the internal partition wall 303 must be at least inside the opening 212.

  However, in the case of a heating cooker incorporated in a kitchen apparatus, it is not known at which position of the opening 212 the end portion of the internal partition wall 303 is arranged due to variation in installation. Therefore, by positioning the terminal end portion of the inner partition wall portion 303 on the inner side of the upper peripheral edge portion of the housing member, the installation condition does not deviate from the position where the opening portion 212 and the housing member are in contact with each other. The end portion of the inner partition wall portion 303 can be positioned inside, and the end portion of the inner partition wall portion 303 can be turned to prevent liquid from being applied to the left heating coil 221.

  Here, the upper part of the inner partition wall 303 is in contact with the lower surface of the top plate 201 of the heating cooker, so that the top plate 201 serves as a lid and blocks liquid that enters the inner partition wall 303 and enters. It is desirable to have a configuration.

  Further, since the internal partition wall portion 303 is robust when integrated with the support member 301, a gap is likely to be generated even if it is in direct contact with the top plate 201 that is also robust. Therefore, by attaching a rubber packing, for example, to the upper part of the internal partition wall 303 and press-bonding it to the lower surface of the top plate 201, liquid intrusion can be prevented.

  In addition, the member attached to the upper part of the internal partition part 303 should just be a material with a certain amount of flexibility, and is not restricted to rubber packing.

A magnetic field is also generated in the side region.

  Therefore, in the vicinity of the left heating coil 221 located on the side opposite to the top plate 201, the heating efficiency is improved by increasing the coupling with the placed pan so that the magnetic field does not heat the surrounding members. In order to increase the frequency, a ferromagnetic material such as a ferrite 241 having a small loss is generally disposed.

The ferrite 241 and the holding material 242 for holding the heating coil are combined to form a heating coil unit.
In the case where the support member 301 is a member different from the housing member that forms the housing portion 208, in order to fix the support member 301, it is necessary to connect to any of the casings that constitute the heating cooker.
At that time, since the holding member 242 and the support member 301 can be integrated by connecting to the holding member 242 in the heating coil unit, for example, the top plate 201 is attached to the top plate 201 by a spring arranged in the housing portion 208. In the induction heating cooker in which the distance between the pan and the left portion heating coil 221 is fixed by pressing, the support member 301 can be installed more easily than being fixed to the housing or the accommodation.

  Moreover, since it is not necessary to adhere | attach on the top plate 201, it can make it easy to remove the top plate 201 at the time of the maintenance of a heating cooker, etc.

  Moreover, since the support member 301 for mounting the left part heating coil 221 can be fixed before the left part heating coil 221 is disposed, the left part heating coil 221 can be easily protruded from the housing part 208. It becomes possible to arrange.
