Hateful. In addition, because the air intake is arranged on an inclined surface that is inclined deeper than the vertical surface formed by the front cover decorative plate, the air intake is not easily blocked by objects placed in front of the user or the main body, and the air intake is It is shielded to reduce problems such as insufficient cooling of the main body and the operation of the main body being stopped.

  In a third aspect of the invention, in particular, in the first or second aspect of the invention, the front surface of the main body bottom on the front cover side is a first bottom plane that is one step higher than the outer periphery of the bottom surface, and the inside of the outer periphery of the bottom surface includes the lower grille. The second bottom plane is one step lower than the bottom outer peripheral portion, and the bottom surface intake port is disposed on the first plane, and the handle portion is disposed below the grille decoration plate.

  As a result, the bottom intake is one step higher than the adjacent bottom, and the other bottoms inside the bottom perimeter are one step lower, so there is a gap between the bottom of the main unit and the bottom of the grille at the back of the bottom intake and the bottom of the grille handle. It becomes narrower, and it is difficult for air to be sucked into the bottom intake port from the rear of the bottom surface of the main body, and the front direction of the main body becomes the intake introduction direction, and intake air is guided from the space under the grille handle to the intake port and the bottom intake port. As a result, the intake flow is strengthened under the handle, the cooling of the handle and the lower surface of the handle is enhanced, and the effect of suppressing the temperature rise is enhanced.

  In addition, since the first bottom plane is one step higher than the surroundings, the intake resistance of the bottom surface intake port is reduced, and the intake port of either the inclined surface or the bottom surface intake port of the first bottom plane is blocked. Even in the case of an accident, the intake opening is secured, and the occurrence of an unexpected malfunction such as the cooling of the inside of the body becomes insufficient and the operation of the body stops.

  In a fourth aspect of the invention, in particular, in any one of the first to third aspects of the invention, a heating coil power supply circuit is arranged behind the cooling fan in the main body inside the front cover, and is provided on the front side of the front cover base. It is a closed plane that does not have an opening in the front vertical plane part of the front cover decorative board. There is no hole in the metal plane that is the front cover decorative board, and the entire front vertical plane part can be covered with metal. Secures the target and thermal strength, making it less likely to cause dents and thermal deformation when hit by objects or hot pots. Furthermore, since the outer surface of the main body in front of the heating coil power supply circuit is covered with a metal front cover decorative board, the effect of reducing electromagnetic wave leakage from the heating coil power supply circuit can be enhanced.

In a fifth aspect of the invention, in particular, in any one of the first to fourth aspects of the invention, a through hole is disposed in the side cover base constituting the side cover, and a side cover decorative plate is provided on the surface side of the side cover base. In this way, air can be applied from the back to the side cover, which is a metal plate, through the through hole, taking away the conduction heat transmitted from the surrounding high-temperature part such as the grill, and reducing the temperature of the outer surface of the main body that the side cover constitutes .

  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)
1, 2, and 3 show a top perspective view, a bottom perspective view, and a longitudinal sectional view of a stationary induction heating cooker according to the first embodiment of the present invention.

  1 to 3, the cooker body 21 is placed on a kitchen table 22. The upper surface of the main body 21 is covered with a stainless steel top frame 24 that surrounds a top plate 23 made of crystallized glass. On the top plate 23, heating portions 25a and 25b are printed. A ventilation panel 26 that covers the external ventilation holes is disposed at the rear of the main body 21 behind the top plate 24. Heating coils 27a and 27b (not shown) constituting induction heating means are arranged inside the main body corresponding to the heating units 25a and 25b.

  FIG. 3 is a vertical cross-sectional view passing through AA near the center of the right heating unit 25a in FIG.

  A grill 28, which is a heating chamber for heating fish and the like, is disposed below the left heating coil 27b. Heating coil power supply circuits 29a and 29b for electrically operating the heating coils 27a and 27b and a cooling fan 30 for sucking air outside the main body 21 are arranged on the side of the grill 28 and below the right heating coil 27a. ing.

  The front surface of the main body 21 includes a grill door portion 31, a front cover 32 that covers the front surface of the main body 21 on the side of the grill door portion 31, and a side cover 33 that is opposite to the front cover 32 on the side of the grill door portion 31. Is done. The cooling fan 30 is disposed inside the front cover 32.

  The front surface of the grill door 31 includes a handle portion 34 and a grill decoration plate 35. The front cover 32 includes a front cover base 36 attached to the main body 21 and a front cover decorative plate 37 provided on the front side of the front cover base 36. The side cover 33 includes a side cover base 38 attached to the main body 21 and a side cover decorative plate 39 provided on the surface side of the side cover base 38. The handle portion 34, the front cover base 36, and the side cover base 38 are all made of heat resistant resin. The material may be a thermosetting resin such as a phenol resin or an unsaturated polyester resin, or a thermoplastic resin such as a polyethylene terephthalate resin or a polybutylene terephthalate resin as long as the temperature rise can withstand.

  The front cover 32 has an inclined surface 40 with a lower portion inclined to the back side. When viewed from the side, the lower portion of the grill door 31 and the side cover 33 has a projection shape substantially the same as the front cover 32, and the lower portion is an inclined surface having the same position and shape as the inclined surface 40 of the front cover 32. .

  The grill decorative plate 35, the front cover decorative plate 37, and the side cover decorative plate 39 are all made of metal, and are made of magnetic stainless steel for the purpose of appearance design, on the front cover base 36, the side cover base 38, and the grill door 31. It is attached and covers most of the vertical plane.

  Further, the inclined surface 40 at the lower part of the front cover base 36 is provided with an air inlet 41, and the cooling fan 30 serves as an inlet for air to be blown inside the main body 21.

  The stationary induction heating cooker main body 21 is usually placed on the kitchen table 22 for use. In other words, in the built-in type, the front side of the kitchen top is the front of the cooker, and the cooker itself is less likely to touch the user directly. Since there is no plate, the front surface of the main body 21 is directly exposed from the front corner ridge line of the top frame 24 on the front of the main body 21, and when using the main body 21, the user's hand and body, hard objects such as pans and pans, There is a high frequency of touching or hitting a hot object, causing the surface of the cooker main body 21 to be damaged or thermally deformed. On the other hand, according to the configuration of the present embodiment, the top frame 24 on the front of the main body 21 is made of stainless steel, and the grill decorative plate 35, the front cover decorative plate 37, and the side cover decorative plate 39 are all made of metal. Since it is made of magnetic stainless steel, the front surface of the main body 21 is harder than that made of resin, so that scratches, dents, thermal deformation, and the like are less likely to occur. At the same time, most of the front vertical plane portion of the main body 21 is covered with metal, and electromagnetic wave leakage of the heating coil 27a can be reduced. The cooling fan 30 is disposed inside the front cover 32 and is located near the front surface of the main body 21, and the lower end of the cooling fan 30 is lower than the motor 65 against the magnetic leakage generated by the motor 65 that drives the cooling fan 30. The grill decorative plate 35, the front cover decorative plate 37, and the side cover decorative plate 39 are made of magnetic metal and have a shielding effect, so that magnetic leakage can be reduced.

  The detailed structure of the grill door 31 includes a handle portion 34 below the grill decoration plate 35, a protective surface 42 at the upper end, a handle 43 disposed below the protective surface 42, and a handle inclined surface 44 below the handle 43. The handle inclined surface 44 is an inclined surface having substantially the same position and shape as the inclined surface 40.

  The intake port 41 disposed on the inclined surface 40 at the lower part of the front cover 32 sucks in outside air from the surroundings. However, the suction from the grill door 31 side becomes a protrusion that forms a partition of the sucked airflow, and the protrusion of the handle 43 Intake airflow flows as shown by arrows in FIGS. 1 and 2 along the longitudinal direction of the shape. For this reason, the protective surface 42 on the handle 43 that is easy to touch when opening and closing the grill door portion 31 and the handle 43 and the handle inclined surface 44 below the handle 43 are cooled, and the temperature is unlikely to rise. In addition, since the air intake 41 is arranged on the inclined surface 40 inclined to the back from the vertical plane formed by the front cover decorative plate 37, the air intake 41 is located behind the front cover decorative plate 37 that is the front surface of the main body 21. It is difficult to be blocked by a user touching the main body 21 or an object placed in front of the main body 21, and the intake 41 is shielded, cooling inside the main body becomes insufficient, and the operation of the main body stops. Defects can be reduced.

  The bottom surface shape of the main body 21 is a first bottom flat surface 46 in which the front surface of the main body bottom surface on the front cover 32 side is one step higher than the other bottom surface outer peripheral portions 45. The second bottom plane 47 is one step lower. The first bottom plane 46 facing the front cover 32 and being one step higher than the bottom surface outer peripheral portion 45 is provided with a bottom suction port 48, and the space before the cooling fan 30 is inclined in the main body 21 inside the bottom suction port 48. It is common with the space inside the intake port 41 arranged on the surface 40. The lower surface position of the handle portion 34 below the grill decoration plate 35 is a surface that is substantially the same height as the bottom peripheral portion 45.

  The first bottom plane 46 in which the bottom suction port 48 is disposed is one step higher than the bottom peripheral portion 45 that is the adjacent bottom surface, and the second bottom plane 47 that is the bottom surface inside the bottom peripheral portion 45 is the bottom peripheral portion 45. Therefore, the back surface of the bottom surface intake port 48 and the back surface of the handle inclined surface 44 of the handle portion 34 are the second bottom plane 47, and the gap with the floor surface is the bottom surface outer peripheral portion 45 or the first bottom surface. It becomes narrower than the portion of the plane 46. Accordingly, since the ventilation gap is narrow from the rear of the bottom surface of the main body 21 to the bottom air intake port 48, it is difficult to inhale, and the intake direction from the front direction of the main body 21 is the intake direction, and the handle 43 and the handle inclination constituting the handle portion 34 The intake air is also guided from the space below the surface 44 to the intake port 41 and the bottom intake port 48. Thereby, the intake flow under the handle 43 is strengthened. As a result, cooling of the handle 43 and the handle inclined surface 44 which is the lower surface of the handle is enhanced, and the effect of suppressing the temperature rise is enhanced, and the handle 43 and the handle inclined surface 44 that are touched when the grill 28 is used can be easily operated. Can be handled easily.

  Further, since the first bottom plane 46 is one step higher than the surrounding bottom surface outer peripheral portion 45, the intake resistance of the bottom surface intake port 48 is reduced, and the intake port 41 disposed on the inclined surface 40 and the bottom surface of the first bottom plane 46. Even when one of the intake ports 48 is blocked, an unexpected opening such as securing the intake opening of the main body 21 and insufficiently cooling the main body 21 to stop the operation of the main body may occur.
