2. Description of the Related Art Conventionally, this type of induction heating cooker has a structure as shown in FIGS. 5 and 6. That is, the upper housing 2 has an upper housing 2 which holds a top plate 1 which is a pot mounting surface, and a lower housing 4 which holds main body components 3 such as circuit parts inside, and the top surface of the upper housing 2 and the top It is made up of adhesive to the back side of board 1,
The outer circumferential dimension of the upper housing 4 is configured to form a substantially vertical surface having approximately the same shape as the outer shape of the top plate 1 in order to avoid direct contact with a high-temperature object such as a pot heated on the top plate 1. Ta. In addition, in order to make the induction heating cooker body more compact, the outer peripheral surface 6 of the lower housing 4 is formed to be approximately perpendicular to the bottom surface 5 that holds the main body components 3, and is continuous with the lower surface of the upper housing 2. It consisted of Furthermore, a recess 7 that serves as a handle for carrying the main body was formed near the center of the left and right outer peripheral surfaces 6 of the lower casing 4 located on the side surfaces of the main body.

0003

[Problem to be Solved by the Invention] However, with this type of structure, when carrying the main body, the handle position is limited to near the center of both sides of the main body. If the device was placed against a wall, the handle on one side would be blocked, making it difficult to move the device. In addition, since the approximately vertical outer circumferential surface of the upper casing that forms the side surface of the main body and the outer circumference of the top plate 1 are almost the same, a pot placed on the top plate may be placed shifted near the outer periphery within the range of the top plate. In such cases, the hands of the person using the main unit could accidentally touch the pot, creating a risk of danger.

[0004] Therefore, the present invention allows the main body to be held from any position without limiting the position of the handle of the main body.
At the same time, the primary objective is to improve the safety of the main unit by making it difficult for the hands of the person using the main unit to accidentally touch the pot even if the pot is placed on the top plate and is placed off-center near the outer periphery of the top plate. It is said that

The second purpose is to ensure a ventilation path for cooling the inside of the main body even when the main body is used in close contact with a wall or the like.

The third purpose is to make it difficult for moisture that has fallen from the upper part of the main body to the floor surface due to boiling over to reach the air inlet for cooling the inside of the main body.

[0007]

[Means for Solving the Problems] In order to achieve the first object, the present invention includes an upper casing whose upper surface is a pot-mounting surface, and a lower casing, the upper casing having a pot-mounting surface. The outer periphery of the mounting surface forms a slope that slopes downward, the outer periphery of the bottom surface of the lower casing forms a slope that slopes upward, and the outer periphery of the upper casing and the outer periphery of the lower casing are continuous. be.

[0008] In order to achieve the second objective, the outer periphery of the upper casing, whose upper surface is a pot-resting surface, forms a slope in which the outer periphery of the pot-mounting surface is inclined downward, and the lower casing has a bottom surface that is slanted downward. The outer periphery forms an upwardly sloping slope, and the outer periphery of the upper casing and the outer periphery of the lower casing are continuous, and the lower casing has legs formed on its bottom surface and a ventilation hole provided on the bottom surface or the slope. It is something.

Furthermore, in order to achieve the third objective, the outer periphery of the upper casing, on which the pot is placed, forms a slope in which the outer periphery of the pot mount surface is inclined downward, and the outer periphery of the lower casing has a bottom surface. forms an upwardly sloping slope, and the lower end surface of the upper case is located outside the upper end surface of the lower case, so that the upper case and the lower case are continuous, and the lower case is connected to the bottom surface of the upper case. It has legs, an intake port on the bottom, and an exhaust port on the bottom or slope.

0010

[Function] Due to the above structure of the induction heating cooker of the present invention, the outer circumferential surface of the main body has a convex shape on the outside of the pot placement surface, and the lower casing forms this convex portion in any part of the main body. You can hold the main body between the slope of the upper casing by inserting your fingertips into the gap between the slope and the floor, so you can hold the main body from any position without limiting the position where you hold the main body, and at the same time Even if a pot placed on the pot placement surface is shifted near the outer periphery of the pot placement surface, there is a slope of the upper casing and a slope of the lower casing between the periphery of the pot placement surface and the outer periphery of the main body. Since the convex portion formed by the above protrudes beyond the outer periphery of the pot, it is difficult for the person using the main body to accidentally touch the pot with his/her hand, thereby improving the safety of the main body.

[0011] Furthermore, in a case where legs are formed on the bottom surface of the lower casing and ventilation holes are provided on the bottom surface or slope, even if the main body is used in close contact with a wall surface, the sloping surface of the lower casing and the wall surface Alternatively, a space is formed between the main body and the floor to ensure a ventilation path for cooling the inside of the main body.

Furthermore, the lower end surface of the upper case is located outside the upper end surface of the lower case, so that the upper case and the lower case are continuous, and the lower case has legs formed on its bottom surface. For models with an intake port on the bottom or an exhaust port on the slope, ensure a distance between the lower part of the outer periphery of the main unit and the intake port, which is the location of spilled boiled water on the floor. This makes it difficult for moisture that falls on the surface to reach the air inlet for internal cooling.

[0013]

[Embodiment] (Embodiment 1) An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 11 is a top plate made of ceramic and is a pot-mounting surface, 12 is an upper casing that holds the top plate 11 on its upper surface, and 13 is a main body with circuit components inside. This is a lower casing that holds component parts 14. The outer periphery 15 of the upper casing 12 forms a slope where the outer periphery of the top plate 11 slopes downward, and the outer periphery 16 of the lower casing 13 forms a slope in which the outside of the mounting surface for components held inside is oriented upward. The outer peripheral part 15 of the upper housing 12 and the outer peripheral part 16 of the lower housing 13 form an inclined slope, and a first boss 17 provided inside the upper housing 12 and a first boss 17 provided inside the lower housing 13 form an inclined surface. It is continuously fixed by a second boss 18.

Next, the operation of the configuration of this embodiment will be explained. With the above configuration, the shape of the outer circumferential surface of the main body is such that the outer side of the top plate 11 is formed by the downwardly inclined outer circumferential part 15 of the upper housing 12 and the upwardly inclined outer circumferential part 16 of the lower housing 13. It has a convex shape, and a gap a is formed between the floor surface and the slope of the lower casing that forms this convex part in any part of the main body, so the position in which the main body can be held is limited. This makes it possible to hold the main body from any position. Furthermore, even if the pot that is the object to be heated is placed off-center near the outer periphery of the top plate 11, the top plate 11
Since the lower end of the outer periphery 15 of the upper housing 12, which is the outer periphery of the main body, is located further outward by an amount b than the outer periphery of the top plate 11,
The outer periphery of the main body can be made to protrude more than the pot placed in the pot.
The safety of the main body can be improved because the hands of the person using the main body are less likely to accidentally touch the pot.

[0016] In this embodiment, the pot-resting surface is a top plate made of ceramic, but it is not limited to this. It may also be configured by

(Embodiment 2) A second embodiment of the present invention will be described below with reference to the drawings.

In FIG. 3, an upper casing 22 that holds a top plate 21, which is a pot-resting surface, has an outer peripheral portion 23 of the top plate 21 forming a downwardly inclined slope, and a main body such as circuit components inside. The lower casing 25 that holds the component 24 has an outer circumference 26 on which the component 24 is placed forming an upwardly inclined slope, and the upper casing 22
The outer periphery 23 of the lower casing 25 and the outer periphery 26 of the lower casing 25 are connected to the upper casing 22.
A first boss 27 provided inside and a second boss 28 provided inside the lower casing 25 are fixed and connected, and the lower casing 25 has legs 29 formed on its lower surface and slopes. Ventilation holes 30 and 31 are provided at the sides.

The operation of the induction heating cooker constructed as described above will be explained below. When using the main body, even if the main body is exposed to an unfavorable condition such as being used in close contact with a wall surface 32, there is no possibility that there will be a gap between the inclined outer circumference 26 surface of the lower casing 25 and the wall surface 32 or the floor surface 33. This is to prevent breakdown of the induction heating cooker main body by forming a space c and ensuring a ventilation path for cooling the inside of the main body.

(Embodiment 3) A third embodiment of the present invention will be described below with reference to the drawings.

In FIG. 4, an upper casing 42 that holds a top plate 41 serving as a pot-resting surface has an outer peripheral portion 43 of the top plate 41 forming a downwardly inclined slope, and a main body such as circuit components inside. The lower casing 45 that holds the component 44 has an outer circumference 46 on which the component 44 is placed forming an upwardly inclined slope, and the upper casing 42
The outer periphery 43 of the lower casing 45 and the outer periphery 46 of the lower casing 45 are connected to the upper casing 42
A first boss 47 provided inside and a second boss 48 provided inside the lower casing 45 are fixed and connected, and the lower casing 45 has legs 49 formed on its bottom surface. Ventilation holes 50 and 51 are provided on the bottom surface and the slope of the outer peripheral portion 46, and the above structure is similar to that of FIG. 3. The difference from the configuration in FIG. 3 is that the lower end surface of the upper casing 42 is
The upper casing 42 and the lower casing 45 are positioned outside the upper end surface of 5.
The second point is that the vent hole 50 on the bottom surface of the lower casing 45 is used as an intake port, and the vent port 51 on the slope of the outer peripheral portion 46 is used as an exhaust port.

[0022] With the above configuration, the position of boiling water that drips from the top plate 41 through the upper casing 42 onto the floor is located directly below the lower end face of the outer circumference 43 of the upper casing 42 and the intake port 50. By ensuring a distance d between them, it is possible to prevent moisture that has fallen from the upper part of the main body to the floor surface, such as boiled water, from reaching the air inlet for cooling the inside of the main body and further intruding into the inside of the main body. Furthermore, since the lower end surface of the upper casing 42 is located outside the upper end surface of the lower casing 45 and the upper casing 42 and the lower casing 45 are connected to each other, the flow of light transmitted from the top plate 41 to the upper casing 42 is made continuous. It is possible to prevent spilled boiled water from entering the inside of the lower casing 45, that is, the inside of the main body.

[0023]

As described above, in the present invention, the outer periphery of the pot mounting surface of the upper casing forms a downwardly inclined slope, and the lower casing forms an upwardly inclined outer periphery of the bottom surface, Since the outer periphery of the upper casing and the outer periphery of the lower casing are continuous, the main body can be held from any position without limiting the position where the main body is held. Even if the placed pot is placed off-center near the outer periphery of the pot placement surface, the hands of the person using the main body are less likely to accidentally touch the pot, thereby improving the safety of the main body.

[0024] Furthermore, in the present invention, the lower casing has legs formed on its bottom surface and a ventilation hole provided on the bottom surface or slope. A space is formed between the inclined surface of the main body and the wall or floor to ensure a ventilation path for cooling the inside of the main body.

Furthermore, in the present invention, the lower end surface of the upper housing is located outside the upper end surface of the lower housing so that the upper housing and the lower housing are continuous, and the lower housing has legs on its bottom surface. It has an air intake port on the bottom and an exhaust port on the bottom or slope, so a distance is ensured between the lower outer periphery of the main unit and the intake port, and moisture that has fallen from the top of the main unit to the floor, such as boiled water, is removed. This makes it difficult for air to reach the air inlet for internal cooling of the main unit.
