Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a heating cooker that cooks food on a grill.
[0002]
[Prior art]
Conventionally, as this type of cooking device, there are ones that are used alone, or ones that are equipped with a cooking stove on the top surface of an induction heating cooking device or the like and are incorporated into a counter of a system kitchen. In this conventional example, a built-in cooking device incorporated in an induction cooking device will be described below with reference to the drawings.
[0003]
FIG. 9 is a cross-sectional view of an induction heating cooker, and particularly shows a configuration of a roaster unit as a heating cooker according to the present invention. In FIG. 9, the induction heating cooker part is provided so that the induction heating coil 3 is pressed against the top plate 2 by a spring above the roaster unit. In addition, there are a control board 6 that controls heating of the induction heating unit and the roaster 5, a cooling device that cools the control board 6, and an operation part 7 that operates the cooker, all of which are housed inside the outer case 1. .
[0004]
Hereinafter, the roaster unit will be described.
[0005]
The configuration of the roaster unit is as follows. Heaters for heating the cooked product with radiant heat are provided above and below the grill 11 inside the cooking cabinet 8. The grill 11 is placed on a tray 12 and can be taken in and out of the cooking cabinet 8 together. When the fish is cooked on the grill 11, fat drips and is received by the tray 12 so that the cooking chamber 8 is not soiled. In addition, oily smoke and water vapor generated during cooking are exhausted out of the cooking chamber 8 through the exhaust tube 13 leading to the outside of the container.
[0006]
In consideration of heat resistance and corrosion resistance, the tray 12 and the cooking chamber 8 generally use horo in many cases. The advantage of using an enamel is that it is easy to remove fat even if it adheres to the wall surface, and dirt is hardly noticeable. On the other hand, the disadvantages are that the surface is brittle and easy to break, and the horo is poorly slidable.
[0007]
In the configuration as described above, the most general configuration is one in which the bottom surface of the saucer is directly placed on the bottom surface of the cooking cabinet and the saucer is slid along with the door (for example, see Patent Document 1).
[0008]
[Patent Document 1]
Japanese Patent No. 3169862 (FIG. 1)
[0009]
[Problems to be solved by the invention]
However, in such a conventional configuration, when the tray is pulled out of the cooking chamber, the tray moves while rubbing against the bottom and side surfaces of the cooking chamber, so the tray treated with the enamel and the cooking chamber rub, so the slipperiness is poor. If an unpleasant rubbing noise is generated with the “key”, or if it is violently hit against the enamel surface, the enamel may peel off, exposing the dough, and corrosion may occur due to salt from the fish.
[0010]
In addition, in order to reduce the contact surface between the saucer and the cooking chamber, when the configuration is adopted in which the saucer is directly supported by the rail, the rail is provided in the chamber, so that the lubricating oil volatilizes and seizes in a high temperature environment during cooking. There is also the risk of salt and sulfur coming from the fish and corroding the metal parts that make up the rail.
[0011]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a heating cooker according to the present invention is attached to a cooking chamber having a built-in heater, a grill net on which food is placed, a saucer on which the grill net is placed and provided freely from the cooking cabinet, and a saucer. A door that is detachably attached via the supporting member, closes the front opening of the cooking chamber, an exhaust path provided at the upper rear of the cooking chamber, a heat shielding case provided continuously on the outer periphery of the cooking chamber, and a heat shielding case A configuration comprising a pair of rails provided on the left and right side surfaces, a control board for controlling the heater, a cooling device for cooling the control board, an operation unit for operating the cooker, and an outer case constituting the cooker outer shell The rail is provided between the heat shield case and the cooking cabinet and is fixed to the heat shield case, the left and right rail ends are fixed by the connecting arm, and the connecting arm and the support bracket of the saucer are locked. , Leh More can be installed to a place lower temperatures, and by food to rail can avoid adhesion of dirt butter, and the like, permanently capable of loading and unloading of the smooth pan.

[0017]
【Example】
Embodiments of the present invention will be described below with reference to the drawings. In addition, a present Example demonstrates the case where a heating cooker is integrated as a roaster unit of an induction heating cooking appliance.
[0018]
Example 1
FIG. 1 is a schematic view of a built-in induction heating cooker in Embodiment 1 of the present invention. In the case of a built-in heating cooker, the entire cooker is dropped into a rectangular hole opened in the worktop of the kitchen and suspended from the worktop.
[0019]
The top surface of the cooker is composed of a glass top plate 2. Under the top plate 2, two induction heating coils 3 and one radiant heater 4 are pressed against the upper top plate 2 by a spring. It is provided as follows. Below these stovetop units, a roaster unit is provided on the left side, a control board 7 is provided on the right side, and an operation unit 6 for operating the cooking device is provided on the right front side.
[0020]
The roaster unit will be described below. In this embodiment, a description will be given of a double-sided roaster in which heaters are provided above and below the grille, but the same effect according to the present invention can be obtained for a single-sided roaster with heaters only on the grille.
[0021]
FIG. 2 is a cross-sectional view for explaining the arrangement of the components of the roaster unit.
[0022]
The cooking chamber 8 contains an upper heater 9 that heats the surface of the fish from above the grill 11 and a lower heater 10 that heats the back of the fish from below the grill 11. The grill 11 is placed on the tray 12 and receives the fat from the fish. The grill 11 can be moved in and out of the cooking chamber 8 in conjunction with the movement of the rail 16 provided outside the cooking chamber 8. It can be slid.
[0023]
In front of the cooking chamber 8, a door 14 having a glass window is provided so as to block the front surface of the cooking chamber 8. A support fitting 15 provided with a hook-like claw is fixed in front of the saucer 12, a hole for engaging with this claw is provided on the back side of the door 14, and the saucer 12 and the door 14 are detachably attached. Yes. For this reason, the tray 12 and the grill 11 can be pulled out of the cooking cabinet 8 at the same time by one operation of pulling out the door 14, and the tray 12 and the grill 12 can be held with the handle of the door 14 without using another tool. The net 11 can be removed outside the cooking chamber 8.
[0024]
Further, an exhaust pipe 13 is provided at the upper rear part of the cooking chamber 8, and oily smoke and water vapor generated during cooking are exhausted out of the cooking cabinet 8 through the exhaust pipe 13 leading to the outside of the vessel.
[0025]
FIG. 3 is a front view of the roaster unit when the door is removed.
[0026]
Rails 16 that slide with ball bearings are provided on both lower sides of the outside of the cooking chamber 8, and the fixed side of the rail 16 is fixed to a heat shield case 17 that surrounds the outer periphery of the cooking chamber 8. In order to permanently ensure the smooth movement of the rail 16, the rail 16 is attached to the outside of the cooking chamber 8 to prevent dirt from adhering to the rail running surface and to prevent volatilization of lubricating oil due to temperature rise. The heat shield case 17 is fixed to prevent heat conduction to the heat shield.
[0027]
Further, in order to make the space for attaching the rail 16 compact, a step is provided on the lower side of the cooking chamber 8 in a stepped manner so that the rail 16 can be accommodated under the flange portion of the tray 12, thereby providing a roaster unit. The spread in the width direction and the height direction can be suppressed as much as possible. As a result, since the distance between the roaster unit that is at a high temperature during cooking and the outer shell of the cooking device can be increased, there is no risk of burns even if the outer shell is touched. In addition, since a large space for accommodating the control board can be secured, the arrangement of the heat generating components can be dispersed, so that the cooling can be efficiently performed.
[0028]
FIG. 4 is a block diagram of the rail tip, the connecting arm, and the support bracket in front of the tray.
[0029]
The connecting arm 18 is substantially L-shaped, and a claw is formed upward on the upper surface side, and attachment holes for fixing to the tip of the rail 16 are opened at both ends. Since the connecting arm 18 protrudes from the cooker for a long distance, there is a possibility that the user may accidentally hit, and the rigidity of the part itself is required. Therefore, the material is preferably made of metal, and it is simplest to make a round bar and is tough.
[0030]
In the present embodiment, since the space below the support fitting 25 is very narrow when the door 14 is closed, the plate material is bent in an L shape to make the structure as compact and light as possible and also have rigidity. Ensures rigidity. However, after the user removes the door 14, in order to temporarily store the rail 16 protruding from the container in the cooking chamber, the heat in the cooking chamber 8 is transmitted during cooking and the connecting arm 18 in a hot state is connected. Although there is a possibility of touching, there is a possibility of burns if the metal connecting arm 18 is in direct contact with the metal. In order to prevent this, it is conceivable to attach a cover that covers the outer periphery of the metal with resin, or to configure the connecting arm 18 with resin.
[0031]
Further, the support metal fitting 15 in front of the tray 12 is perforated at a position where it engages with the claw of the connecting arm 18, and the movement is restricted in the horizontal direction in the pulling-out direction of the door 14 and is supported only in the upward direction. The metal fitting 15 can be removed from the pawl. For this reason, even when cooking with water on the saucer 12, the saucer 12 in which water and fat are accumulated can be taken out of the cooking chamber horizontally after cooking, and there is a concern that water or oil may be accidentally tilted and spilled. Disappear.
[0032]
FIG. 5 is a configuration diagram of another engagement method of the connecting arm and the support metal fitting.
[0033]
In many cases, the support fitting 15 is fixed to the tray 12 and subjected to engraving. However, in the engraving process, the hole engaging with the pawl may be filled with the engraving. As a countermeasure against such a phenomenon, the engagement with the pawl of the connecting arm 18 is not a hole, but is engaged with the end face of the support bracket 15 or a U-shaped or V-shaped groove to restrict the movement in the horizontal direction. The same effect can be obtained.
[0034]
With the above-described configuration, it is possible to prevent dirt and the like from adhering to the rail 16 provided for smoothly removing the tray 12 from the cooking cabinet 8, and to keep the atmospheric temperature of the rail lower than the volatilization temperature of the lubricating oil. Smooth sliding or sliding can be ensured.
[0035]
In addition, a resin component can be used for the bearing by lowering the temperature, so that sliding noise and rolling noise can be further reduced and vibration can be absorbed. Further, even when the tray 8 and the door 14 are removed from the rail 16 by the connecting arm, the protruding amounts of the left and right rails are the same, so that the tray can be easily placed on the connecting arm and the connecting arm 18 is visually observed. Since the engagement of the support bracket 25 can be confirmed, it is possible to prevent the possibility of dropping the tray 12 by mistake.
[0036]
(Example 2)
FIG. 6 is a configuration diagram of the rail and the connecting arm in the second embodiment of the present invention.
[0037]
In the first embodiment, the connecting arm 18 is directly attached to the tip of the rail 16, whereas a resin rail cover 19 is attached to the tip of the rail 16, and the connecting arm 18 is fixed to the rail cover 19. ing. The cross section of the tip of the rail 16 is substantially U-shaped, and a square hole is opened near the top of the top surface. The rail cover 19 is provided with a flange surface so as to conceal the front end surface of the rail 16, and the base side from the flange surface can be inserted inside the rail 16. Are provided so that the door 14 cannot be pulled out in the pulling direction. A boss that fits into the hole of the connecting arm 18 is provided at the front end of the flange surface of the rail cover 19, and is fixed so that the connecting arm 18 and the rail cover 19 can move freely with screws.
[0038]
FIG. 7 is a cross-sectional view of the rail cover attached.
[0039]
The size of the boss of the rail cover 19 is slightly smaller than the size of the hole so that the fitting with the connecting arm 18 is free of clearance, and the height is higher than the plate thickness of the connecting arm 18. Thus, by securing a certain amount of play (about 1 mm) for attachment of the connecting arm 18, the left and right rails 16 are not attached horizontally (the tip direction is widened, narrowed or twisted). Even in a state in which these are combined, the smooth movement can be ensured without interfering with the back and forth movement of the rail 16 by fixing the connecting arm 18.
[0040]
With the configuration as described above, the resin 16 is fixed between the rail 16 and the connecting arm 18 so that the heat during cooking is transmitted to the rail 16 and the heat is not touched by hand. Since the resin component stops the conduction to the connecting arm 18, the connecting arm 18 that is most easily touched by the user is prevented from being heated to a high temperature, and even if the connecting arm 18 is accidentally touched, there is a risk of being burned. Disappear.
[0041]
Example 3
FIG. 8 is a configuration diagram of the rail and the connecting arm in the third embodiment of the present invention.
[0042]
In Example 1, although the structure which covers metal connection arms 18 with resin was described, in this Example 3, rubber packing 20 was attached to the cooking chamber 8 side of connection arms 18. When the door is closed, the packing 20 is attached so as to close the hole through which the rail 16 of the outer front plate 21 passes. In addition, it is also conceivable that the left and right packings 20 are connected by extending the left and right packings. It is also conceivable that the metal connecting arm 18 is covered with rubber instead of the resin component.
[0043]
With the configuration as described above, the packing 20 is attached around the hole through which the rail 16 of the front plate constituting the outer shell of the container passes, and during cooking, oil smoke passes from the hole through the gap between the front plate and the back surface of the door 14. Intrusion can be prevented, and deterioration of slidability due to corrosion of the rail 16 and adhesion of dirt can be prevented. Further, by covering the entire metal connecting arm 18 with the packing 20, even if the user touches the connecting arm 18 by mistake, there will be no burns. Moreover, since the clearance at the door 14 side can be reduced, smoke leakage from the front surface of the roaster can be prevented.
[0044]
【The invention's effect】
By the invention as described above, the rail for improving the sliding property between the saucer and the cooking chamber can be installed at a lower temperature, and the adhesion of dirt such as fat due to the food to the rail can be avoided, and it is permanent. The tray can be smoothly put in and out, and the tray can be easily attached and detached.
