DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention enhances safety by providing the distance between the user and the object to be heated, that is, the position of the heating portion, at the back of the top plate, and at the same time, improves the safety of the top plate. The purpose is to make it possible to easily provide the operation unit on the top.

An embodiment of the present invention will be described below with reference to the drawings. In this example, an induction heating cooker having a so-called three-port stove section having three heating sections will be described as the heating cooker of the present invention.

FIG. 1 is an external perspective view of a heating cooker according to an embodiment of the present invention, and FIG. 2 is an external perspective view of another example of the heating cooker. In FIG. 1, 11 is a main body that forms the outer shell, 12 is a top plate provided on the top of the main body 11, 13 is a top frame provided on the outer periphery of the main body 1,
Reference numerals 4 and 15 denote induction heating units provided on the upper surface of the top plate 12 for placing and heating an object to be heated, such as a pan, which generates heat by induction heating, and 16 denotes an object to be heated, such as a pot, which cannot be used in induction heating. This is a radiant heating unit for heating by heating. As shown in the figure, induction heating units 14 and 15 are provided on the front side of the top plate 12, that is, the user side, and a radiation heating unit 16 is provided on the back side. Also, the top plate 1
An induction heating unit (not shown) corresponding to the induction heating units 14 and 15 is provided in the lower part of 2, and a radiation heating unit 16 is also provided.
Corresponding to the above, a radiant heating means (not shown) is provided.

Further, an intake port cover 17 (not shown) for covering the intake port and an exhaust port cover 18 for covering the exhaust port (not shown) are provided on both sides of the top plate 12 in the upper part of the main body 11. The intake port cover 17 and the exhaust port cover 18 are each surrounded by the top frame 13. Further, in FIG. 1, an operation unit 19 on the surface and a display unit 20 for displaying the contents of the operation are provided on the front side of the top plate 12.

On the side surface of the main body 11, a roaster portion 21 for grilling fish and the like, an operation portion 22 having all keys necessary for cooking and a display portion 2 for displaying key inputs.
3 is provided.

The function of the heating cooker configured as described above will be described below. The feature of this embodiment is that the intake port cover 17 and the exhaust port cover 1 are provided on both sides of the top plate 12 at the back of the main body 11, that is, at both corners at the back of the main body 11.
8 is provided. At this time, since the intake port and the exhaust port are provided at both corners of the main body 11, the cross-sectional area can be made the same as the conventional cross-sectional area without affecting the object to be heated placed on the radiant heating section 16. . Therefore,
The position can be changed while maintaining the same air supply and exhaust capacity.

By doing so, the depth of the top plate 12, that is, the distance from the front side to the top side of the top plate 12 can be increased. This allows
The distance D from the center O of the radiant heating section 16 to the outer periphery of the main body 11 becomes longer, which allows for room. That is, even if the object to be heated is placed on the radiant heating section 16, a space is created between the object to be heated and the outer circumference of the main body 11. Therefore, in order to reduce this space, the present embodiment is characterized in that each heating unit is moved to the inner side while maintaining the relative positional relationship of each heating unit. As a result, the distance between the induction heating units 14 and 15 and the front top frame 13 is increased.

From the center of the radiant heating section 16 to the main body 11
In order to obtain a practically appropriate distance to the outer circumference, an object to be heated was placed on the radiant heating part 16 and a practical study was conducted. As a result, it was practical that the distance D from the center O of the radiant heating section 16 to the outer circumference of the main body 11 was 90 mm or more and 140 mm or less. This is because if the length is shorter than 90 mm, there is a greater risk that the object to be heated will stick out of the outer periphery of the main body 11 and come into contact with installations other than the cooking device, making it difficult to handle.

On the other hand, if it exceeds 120 mm, the distance between the above-mentioned induction heating parts 14 and 15 and the front top frame 13 becomes short, and it becomes difficult to provide an operating part on the top plate 12.

As described above, according to the present embodiment, the position of the radiant heating portion 16 is provided in the depth of the top plate 12 relative to the position of the radiant heating portion of the conventional cooking device. Therefore, the user is less likely to be affected by the radiant heat of the radiant heating unit 6, and the safety can be further improved. In particular, when the front heating part is a radiant heating part, the effect becomes large.

Further, since the heating part is provided at the rear, there is a margin in the area up to the top frame 13 in front of the heating part.
The operation part and the display part can be arranged in this part.

FIG. 1 shows a case where frequently used keys are selected and arranged on the operation unit 19 on the surface. This is because by reducing the number of keys of the operation unit 19, the area of the operation unit 19 is reduced and the operation unit is separated from the heating unit, so that the operation unit 19 is less susceptible to the thermal influence, and the operation is afforded. Is. This configuration is particularly effective when the front heating unit is a radiant heating unit.

However, when the distance between the heating portion and the top frame 13 is sufficient as in the present embodiment and the heating portion in front is an induction heating portion, the induction heating does not directly generate high temperature heat. As shown in FIG. 2, a display unit 25 for displaying all keys and key inputs required for cooking on the operation unit 24 on the surface.
And can be provided.

By using a liquid crystal display as the display unit, it is possible to display information related to cooking such as thermal power display, cooking timer display, fried food temperature control display, and abnormality display. Furthermore, by providing the operation unit 24 and the display unit 25 on the surface, the operation unit 22 and the display unit 23 on the side surface can be omitted. This makes it possible to increase the size of the roaster unit or to provide its position in the center.

Further, in this embodiment, the intake cover 7 and the exhaust cover 8 are separately provided, so that they are easy to wash.
Further, since the intake port and the exhaust port are separated from each other, there is an effect that the exhaust gas is hardly sucked.

In the present embodiment, the case where the top frame is provided has been described. However, the construction may be examined according to the model and the top plate may be omitted if the purpose of the present embodiment is met.

Further, the positional relationship between the intake port and the exhaust port is not limited to this embodiment, and the exhaust port may be provided on the side where the roaster section is located.

As an induction cooker, two induction heating units are used.
Although the case where one mouth and one radiant heating unit are used has been described, it is not limited to this combination, and it goes without saying that another three-comb stove may be used.

Further, in this embodiment, one side is the intake port and the other side is the exhaust port, but both are intake ports (exhaust is performed on the front face of the main body) or both are exhaust ports (intake is performed from inside the cabinet etc.). Also, the same effect can be obtained.

[0036]

As described above, according to the invention described in claims 1 to 6, the distance between the front surface of the top plate and the induction heating portion is increased while maintaining the conventional external dimensions, thereby further increasing safety. Can be improved. Further, the operation unit and / or the display unit can be provided without difficulty.
