Description

  The present invention relates to a heating cooker having a heating chamber for cooking an object to be cooked such as fish on a grill.

  Conventional heating cookers use a heating chamber alone, or in addition to the heating chamber, a stove such as an induction heating cooking device is provided on the top surface and incorporated into a counter of a system kitchen.

  The roaster part of the latter cooking device has an upper heater for cooking the front side (upper side) of the food to be cooked from above the grille, and a back side (bottom side) of the cooked food from the bottom of the grille. A lower heater for cooking the side) is built in, and the grill is placed on a saucer installed in a heating chamber. The water and fat coming out of the cooked food are stored in a tray and are not leaked to the bottom of the heating cabinet.

  Further, smoke and water vapor generated during cooking are exhausted out of the heating chamber through an exhaust pipe communicating to the outside. The saucer and the heating cabinet are configured in consideration of heat resistance. However, they are easily soiled by fish fat or the like, and are often subjected to enamel treatment so that the soil is easily removed. In some cases, a material having heat resistance and corrosion resistance such as stainless steel is used as it is.

  In the above configuration, the tray is configured to be in sliding contact with the bottom surface of the heating chamber via a metal arm on the lower side of the flange portion (see, for example, Patent Document 1), or a rail and a pulley on the inner wall of the heating chamber. There is one that is provided and directly slides the tray (for example, see Patent Document 2). Furthermore, as for the simple thing, a saucer is directly mounted in the heating-chamber bottom face.

  However, in such a configuration, when pulling out the door connected to the saucer, the saucer and the arm slide on the convex portions provided on the bottom surface and the side surface of the heating chamber. Not only is the slidability between the chambers and between the metal arm and the heating chamber worse, but there are no lateral restrictions, so the horoes collide and in some cases the horo may be missing.

  In addition, even when sliding through a metal arm, the slidability is poor, the hollow side may be chipped, or the metal surface-treated portion may be worn out, resulting in a decrease in corrosion resistance and corrosion. Further, when the rail is provided in the heating chamber, there is a possibility that the lubricating oil volatilizes and burns at a high temperature, or the salt or sulfur content from the fish corrodes the metal constituting the rail.

  In order to solve such a problem, a configuration has been proposed in which the fixed side of the rail is fixed to the heat shield case, and the fixed side and the movable side of the rail are provided between the heat shield case and the heating chamber ( For example, see Patent Document 3.)

  In this cooking device, the rail is provided outside the heating chamber, thereby eliminating problems caused by high temperatures and dirt. In addition, the tray and the holding body for holding the tray can be detachably attached to the door, and the handle can be pulled out horizontally, so that the tray can be pulled out of the heating chamber by sliding the rail. A stopper for preventing the tray from popping out is provided in front of the rail, and the tray can be taken out from the heating chamber by lifting the door upward and getting over the stopper.

  In the cooking device according to the present invention having the above-described configuration, when a cooking object such as fish is inserted into the heating chamber 5 and cooked, when the handle 50 of the door 19 is gripped and pulled to the front side, the rail unit 16a, The movable rail 16b slides with respect to the fixed rail, and the heating chamber 5 is opened. Moreover, since the engaging part 76 of the tray holding body 64 is fitted in the holding body support groove 44a formed in the holding body support section 44, the tray holding body 64 and the tray held by the tray holding body 64 are provided. 66 and the grill 68 placed on the tray 66 are pulled out together with the door 19 and the movable rail. At this time, the sliding contact portion 72 of the tray holder 64 is in sliding contact with the sliding contact member 70 projecting from the bottom surface of the heating chamber 5, and the sliding contact member 70 is formed of a material having a very low coefficient of friction such as fluororesin. Therefore, the heating chamber 5 is opened smoothly.

  Next, water is poured into the saucer 66 using the height of the convex portions 84 and 86 formed on the bottom surface of the saucer 66 as a guide, and then the object to be cooked is placed on the grill net 68. When the door 19 is pulled out from the heating chamber 5 most, the rear end of the sliding contact portion 72 of the tray holding body 64 is supported by the inside of the opening surface of the heating chamber 5 (sliding contact member 70). Since the dimensions of the tray positioning portions 74 and 78 of the rail units 16a and 16b, the tray 66, and the tray holder 64 are set so that the rear end is positioned on the near side of the opening surface, the tray 66 is lifted and taken out. On the contrary, it is extremely easy to place the tray 66 on the tray holder 64. Furthermore, it is very easy to pour water or place the food to be cooked on the grill 68.

  Thereafter, when the door 19 is pressed toward the heating chamber 19, the cooking object placed on the grill 68 is accommodated in the heating chamber 5, and as shown in FIG. 2, the upper heater is placed above the cooking object. 6 is disposed, and the lower heater 7 is disposed between the tray 66 and the grill 68. Therefore, when a predetermined operation is performed by operating the operation unit 26, the upper heater 6 and the lower heater 7 are energized, and both sides of the object to be cooked are heated and cooked by the upper heater 6 and the lower heater 7.

  During cooking, the cooling fan 25 is activated, and outside air enters from an air inlet 34 provided behind the top plate 11, and a part of the cooling fan 25 faces the lowermost circuit board 24. The air discharged from 36 is blown toward the circuit board 24 to cool the heat generating components such as the switching element and the diode bridge. Further, the air that flows into the opening 29 of the middle partition plate 22 through the opening 30 of the substrate holding plate 28 and the air that flows from the periphery of the middle partition plate 22 are caused by the rail units 16 a and 16 b and the heat shield plate 23. After being guided to the space with the lower casing 2 and passing through the space with the lower casing 2 of the heat shield 23 to cool the rail units 16a and 16b and the casing 2, the exhaust port 35 is discharged to the outside.

  It is to be noted that a gap is easily generated in the heating chamber 5 due to attachment of a component such as a heater, and the air whose pressure is increased by the cooling fan 25 enters the chamber from the outside of the heating chamber 5 through the clearance, Although it is easy to leak from the gap between the front panel 38, the packing 43 provided on the heating chamber 5 abuts against the door 19 and the packing 62 provided on the door 19 contacts the front panel 38 during cooking. The smoke generated in the heating chamber 5 is prevented from leaking to the outside by the two packings 43 and 62.

  In addition, the air that has cooled the rail unit 16b is blown toward the door 19 from a plurality of slits 39 formed in the lower portion of the front panel 38 around the opening of the heating chamber 5, thereby acting as if it were an air curtain. The smoke generated in the heating chamber 5 is prevented from leaking to the outside. A part of the air blown toward the door 19 is blown toward the openings 52 and 54 formed in the door cover 46, and the pressure in the space between the door 19 and the door cover 46 is increased. Prevents smoke from leaking outside.

  In addition, air from the upper and lower outlets 36 and 36 of the cooling fan 25 is blown toward the circuit board 24 of the substrate holding plate 28 and is divided into multiple layers from the first floor to the third floor. Cools heat-generating parts such as diode bridges. Thereafter, the air passing through the circuit board 24 from the opening formed on the upper surface of the heating coil support 27 provided on the uppermost floor is directed to the opening of the board holding plate 28 on the side opposite to the cooling fan 25. The air is blown upward from the heating coil support 27, and cooling air flows from the heating coil 13 b to the heating coil 13 a and the housing 2, and is then discharged to the outside through the exhaust port 35.

  When the cooking of the object to be cooked is completed, when the handle 50 of the door 19 is gripped and pulled toward the front side, the movable rails of the rail units 16a and 16b slide with respect to the fixed rail, and the tray holder 64 and the tray 66. Since the grill net 68 is pulled out integrally, the object to be cooked can be easily taken out. In addition, by adopting the rail units 16a and 16b, even if the handle 50 is provided at the upper end portion of the door 19, the cooking object can be smoothly put in and out, and the upper end portion of the door 19 is made of the resin handle 50. By covering with, the safety or operability for the user is improved.

  As described above, the door 19 locked to the connection fitting 18 by the lock piece 56 is unlocked by pressing the pin 58 provided on the door 19, and after unlocking, the door 19 is lifted upward. Since the door 19 can be removed from the connection fitting 18, when the door 19 becomes dirty, the door 19 can be removed from the connection fitting 18 and cleaned appropriately. Further, when the door 19 is pulled out most from the heating chamber 5, the dimensions are set so that the rear end of the tray 66 is positioned on the near side of the opening surface. The attachment / detachment of the net 68, the attachment / detachment of the tray 66 to / from the tray holder 64, or the attachment / detachment of the tray holder 64 to / from the connection fitting 18 can be performed very easily, and each member can be appropriately cleaned as necessary.

  In addition, the structure which attaches the door 19 to the connection metal fitting 18 detachably is not necessarily required, and the door 19 may be fixed to the connection metal fitting 18. Moreover, although the connection metal fitting 18 demonstrated as what connects the front-end part of the movable rail of rail unit 16a, 16b mutually, the door 19 can also be attached to the front-end part of a movable rail, without providing the connection metal fitting 18. FIG. In this case, the tray holder 64 may be engaged with each of the pair of movable rails.
