, 12 in a removable manner.

Further, 22 is an exhaust port of the inner chamber 8, 23 is an exhaust port of the cooking device main body 1, and a lid body 25 having an exhaust hole 24 is provided thereon.

26 is a door body, 27 is a combustion air intake for the lower burners 3, 3, 28 is a protrusion for preventing the movement of the water tray 19, 35 is a packing, and 48 is an inlet for the water tray 19. , 47 arranged on the front side of the cooking device main body 1 is an operating knob for a gas cock 57, 87 is an operating knob for a temperature regulating thermostat (not shown), and 56 is a switching knob.

This switching knob 56 moves the heat equalizing plates 5, 5 disposed in the interior chamber 8 to positions corresponding to the cooking method, thereby changing the width of the central hot air flow passage 53.

That is, the switching knob 56 is connected to the elongated hole 4 on the front surface of the cooking device main body 1.
The rear end of the drive rod 42 is bent downward and then loosely fitted into a drive receiving plate 43 disposed on the outside of the inner chamber wall 7. installed in condition.

The approximate center of the drive rod 42 is loosely inserted into a through hole provided at one end of the horizontal interlocking plate 39.

A rotating rod 36 is attached to one end of a horizontal interlocking plate 39 that passes through the lower part of the inner chamber 8 from side to side, and a rotating rod 37 is attached to the other end of the horizontal interlocking plate 39 in a loosely fitted state. The other ends of the rotation rods 36 and 37 protrude into the interior chamber 8 through through holes 51 and 51 provided on both left and right walls of the interior chamber wall 7, and are provided on the lower surface of the heat equalizing plates 5 and 5. Blind holes 52, 52 rest on the other ends of these pivot rods 36, 37.

Reference numeral 13 denotes a receiving plate which is attached to the outside of the inner chamber wall 7 and supports the vertical portions 38 of the rotating rods 36 and 37 in a loosely fitted state in its through hole, and 40 and 40 are auxiliary rotating rods. 40, one end of the auxiliary rotation rods 40, 40 is loosely fitted into a through hole of a receiving plate 4L41 disposed on the outside of the inner chamber wall 7, and the other end of the auxiliary rotation rods 40, 40 protrudes into the inner chamber 8 through a through hole provided in the inner chamber wall 7, and supports the heat equalizing plates 5, 5 in the same way as the rotating rods 36, 37.

The soaking plates 5, 5 are connected to the rotating rods 36, 37 and the auxiliary rotating rod 40.
, 40 so that it can be easily attached and detached.

However, now the switching knob 56 is in the state shown by the solid line in FIG. 5a.
When the horizontal interlocking plate 39 is moved to the left via the drive rod 42, the left and right rotation rods 36, 37 move to the vertical portion 38. 38 as an axis in opposite directions, that is, toward the center of the inner chamber 8, and accordingly
5 is moved toward the center of the inner chamber 8 as indicated by the arrow, thereby narrowing the width of the central hot air flow passage 53 as shown in the chain diagram.

The auxiliary rotating rods 40, 40 also swing their heads as the heat equalizing plates 5, 5 move, so that the amount of movement at the front and rear ends of the heat equalizing plates 5 is equalized.

Conversely, when the switching knob 56 is moved to the right, the horizontal interlocking plate 3
9 is swung to the right, and accordingly both of the heat equalizing plates 5, 5 are moved toward the inner chamber wall 7 side.

In this manner, by operating the switching knob 56, the left and right heat equalizing plates 5, 5 are brought closer to the center or moved toward the inner chamber wall 7, thereby making the width of the central hot air flow passage 53 variable.

Furthermore, when the switching knob 56 is operated, the drive rod 42 not only moves the horizontal interlocking plate 39, but also moves the upper sliding plate with which the cam plate 61 engages via the lower sliding plate 60, as shown in FIG. 6
2 is moved up and down, and the rotational direction of a spindle 58 of a gas tank 57 that supplies gas to the upper and lower burners 2 and 3 is restricted to one direction in accordance with the operating direction of the switching knob 56.

That is, 63 is a door lock mounting plate, which is disposed and fixed above the switching knob 56, has a spindle insertion hole 170 approximately in the center, and has a first restriction protruding forward at a position deviated diagonally upward and to the right. It has a pin 71.

72 is a mounting piece to the cooking device main body 1.

A lower sliding plate 60 is arranged in front of this door lock mounting plate 63.

This lower sliding plate 60 is vertically long and has a gas tank 57 on its upper part.
A vertically elongated hole 73 into which the spindle 58 is loosely fitted is formed, and a through hole 74 into which the drive rod 42 is loosely fitted is formed at the lower end.

It also has a second regulating pin 75 that protrudes forward at a position offset downward from the right.

The upper sliding plate 62 disposed in front of the lower sliding plate 60 has a vertically elongated hole 7 approximately in the center into which the spindle 58 of the gas stick 57 is loosely fitted.
6, the upper part from the right side is a regulating vertically elongated hole 77 into which the first regulating pin 71 is fitted and slides, and the lower part thereof is a regulating horizontally elongated hole 78 into which the second regulating pin 75 is fitted and slides. have.

Two protrusions 79 and 8 extend forward from this sliding upper plate 62.
0 stands out.

One is a protrusion 80 formed by bending a short piece forward from the lower edge of the vertical hole 76, and the other is the upper edge of the sliding upper plate 62, which is spaced apart from the upper edge of the vertical hole 76. This is a protrusion 79 formed by bending a short piece further forward.

A cam plate 61 is arranged in front of this sliding upper plate 62.

The semicircular cam plate 61 has a rectangular fitting hole 81 bored in the center of the semicircle, which engages the spindle 58 of the gas tank 57 and rotates the cam plate 61 together with the spindle 58 which has a rectangular cross section. The edge of the cam part has protrusions 79, 80
It is located further to the left.

The length of the cam plate 61 as a percentage of the maximum width is 79.8% of the above-mentioned protrusions.
It is made smaller than the width between 0.

64 is a pressing spring arranged in front of the cam plate 61;
The spring portion 65 has an insertion hole 66 into which the spindle 58 of the gas stick 57 is loosely fitted, and presses the cam plate 61, the upper sliding plate 62, and the lower sliding plate 60 backward.

47 is a gas tank 5 attached to the tip of the spindle 58
This is the number 7 operation knob.

As described above, when the switching knob 56 is moved to the right in order to move the heat equalizing plate 5, the lower sliding plate 60 into which the drive rod 42 is loosely fitted moves to the right.

At this time, the lower sliding plate 60 does not interfere with the horizontal movement of the drive rod 42 due to the vertically elongated hole 73 into which the spindle 58 is loosely fitted.

Therefore, the second regulating pin 75 moves to the right and rises.

Due to this movement of the lower sliding plate 60, the upper sliding plate 62, which fits the second regulating pin 75 into the horizontally elongated regulating hole 78, moves upward as the second regulating pin 75 rises.

At this time, the sliding upper plate 62 vertically rises without moving to the right due to the longitudinal hole 76 into which the spindle 58 is loosely fitted and the longitudinal longitudinal hole 77 into which the first regulating pin 71 is fitted.

As a result, the protrusion 80 approaches the spindle 58 while the other protrusion 79 moves away.

In this state, when the operating knob 47 is turned to rotate the spindle 58 to open the gas cock 57, the lower edge 68 of the cam of the cam plate 61, which rotates together with the spindle 58, hits the protrusion 80 against the counterclockwise rotation. contact,
However, since the protrusion 79 is separated from the spindle 58, the upper edge 67 of the cam portion of the cam plate 61 does not come into contact with the protrusion 79, and the rotation of the spindle 58 is prevented. forgive.

Next, return the operating knob 47 to its original position to close the gas cock 57, and conversely move the switching knob 47 to the left to open the drive rod 42,
The upper sliding plate 62 is connected to the second regulating pin 75 via the lower sliding plate 60.
Since it is located below the right side of the elongated hole 73, it moves vertically downward, and as a result, the protrusion 80 moves away from the spindle 58 and the protrusion 79 approaches the spindle 58.

In this way, the protrusion that the cam plate 61 abuts is reversed from the previous one, preventing the spindle 58 from rotating clockwise and allowing it to rotate counterclockwise.

Now, in the gas tank 57 as shown in FIG. 7, when the spindle 58 is rotated clockwise, the gas inlet 82 is brought into communication with the upper burner gas outlet 83 and the lower burner outlet 84. When gas is supplied to the upper and lower burners 2 and 3 and rotated counterclockwise, the inlet 82 and the lower burner gas outlet 84 communicate with each other, so that gas is supplied only to the lower burner 3. .

In this embodiment, when using it as a grill, the switching knob 56 is moved to the right to move the heat equalizing plates 5, 5 to the outermost positions on the inner chamber wall 7 side, respectively, as shown in FIG. The soaking plates 5, 5 are stored below the sub-heating plate 15.

At this time, the upper and lower sliding plates 60 and 62 simultaneously move to position the protrusion 80 to the right of the lower cam edge 68 of the cam plate 61, so the operating knob 47 can only be rotated clockwise. When gas is supplied to the lower burners 2 and 3 and the upper and lower burners 2 and 3 are ignited, the hot air obtained from the lower burner 3 is transferred to the central hot air that is wide open between the heat distribution plates 5 and 5. The grill 21 passes through the flow path 53
The radiant heat from the upper burner 2 is radiated directly onto the upper surface of the grill 21 to grill the food on the grill 21 from above.

In other words, the object to be cooked is grilled from above and below at the same time, and grill cooking can be performed without turning the object over.

The oil and fat generated from the food to be cooked falls onto the water in the water tray 19, and at the same time, the oil and smoke are reburned by the combustion heat of the upper burner 2 and are discharged through the exhaust ports 22 and 23 in a smokeless state.

Furthermore, since the heat equalizing plates 5, 5 are located on the left and right inner chamber walls 7 and close off the side hot air flow passage 6, the lower burner 3 is exposed to oil smoke.
Prevent stains.

When used as an oven, the switching knob 56 is moved to the left to move the soaking plates 5, 5 toward the center, respectively.

As shown in FIGS. 1 and 3, when the heat equalizing plates 5, 5 move to the position where the L-shaped engagement piece 14 and the bent piece part 15 engage, the heat distribution plate 4 hangs down from the heat equalizing plate 5. , 4 are placed in front of the lower burner 3 to narrow the width of the central hot air flow passage 53, and a heat equalizing plate 5, 5 is placed above the lower burner 3.
and the sub-uniforming plate 15 are located, and the inner chamber wall 7 of the sub-uniforming plate 15 is located.
A lateral hot air flow passage 6 opens on the side.

Simultaneously with this movement of the heat equalizing plate 5, the lower sliding plate 60 moves to the left and the upper sliding plate 62 moves downward due to the movement of the drive rod 42, and the protrusion 79 is moved to the upper edge 67 of the cam portion of the cam plate 61. In order to position it to the right, the operating knob 47 can only be rotated counterclockwise.

In this state, when the spindle 58 is rotated using the operation knob 47 and the gas outlet 84 for the lower burner is opened, gas is supplied only to the lower burner 3, and when this gas is ignited and burned, the gas generated by the combustion of the lower burners 3, 3 is supplied. The hot air hits the hanging heat distribution plates 4, 4, and the heat distribution plates 4 and the heat equalizing plates 5, 5
At the same time, the hot air is divided into two streams by the heat distribution plate 4.

A part of the hot air passes under the heat distribution plate 4 as shown by the arrow in FIG. It is directly introduced into the lower center of the inner space, causing the temperature inside the refrigerator to rise rapidly, bypassing the saucer 20 and rising.

In addition, other hot air is guided from the lower surface of the heat equalizing plate 5 to the lower surface of the sub-heat equalizing plate 15 to the side hot air flow passages 6, 6 as shown by the arrow, and when passing through the side of the saucer 20. Central hot air flow passage 5
The hot air that has passed through the interior chamber 8 joins with the hot air and hits the ceiling side wall 31, and the hot air circulated by the ceiling side wall 31 becomes a vortex and stays in the upper space of the interior room 8.

In this way, the food to be cooked on the saucer 20 is exposed to the hot air flow supplied from the lower burners 3, 3 that stays in a swirling state in the upper part of the inner chamber 8, and the lower surface of the saucer 20 introduced through the central hot air passage 53. Baking is carried out simultaneously from the top, bottom, left and right by the hot air flow and the radiant heat from the heated soaking plates 5, 5 and sub-heating plates 15, 15.

The hot airflow after heating the food is discharged from the exhaust ports 22 and 23.

Reference numeral 86 in FIG. 1 denotes an interlocking pin which is disposed on the front surface of the cooking device main body 1 and is freely retractable from the front panel of the cooking device main body 1 by means of the door 26, and is connected to the door lock mounting plate 63 described above.
Stopper engagement hole 85 and spindle 58 provided in
When the door 26 is opened and the interlocking pin 86 is protruded, the spindle 5B of the gas stove 57 for ignition is
When the door 26 is closed and the interlocking pin 86 is pressed, the stopper engages with the spindle 58 and locks it to prevent it from being accidentally ignited by a child or the like.

Of course, once the ignition is ignited, that is, after the spindle 58 is rotated, this stopper is prevented from engaging with the spindle 58 regardless of the state of the door 26.

In the present invention, as described above, by operating the switching knob placed on the outer surface of the cooker body, the heat equalizing plate placed above each lower burner moves to change the width of the central hot air flow passage to adjust the temperature inside the cooker. The path of heat propagation changes, and for this reason, when grilling, the upper and lower burners are used to grill, but the hot air from the combustion of the lower burner is directly introduced into the inner chamber without being obstructed by the heat equalizing plate. In addition, when cooking in the oven, only the lower burner is used, but the heat distribution plate works to ensure even heat distribution, and the heat propagation of the burners is good. Moreover, the rotation direction of the operation knob on the gas cock that selectively supplies gas to both the upper and lower burners is controlled by the interlocking mechanism that moves both heat equalizing plates by operating the switching knob. This means that when you move the switch knob to change the position of the equalizer plate to grill or oven, the upper and lower burners will automatically switch to the corresponding position. This is because even though the heat equalizing plate has been moved to the grill position, the only burner that is lit is the bottom burner, which is used for the oven, resulting in uneven heat distribution to the food being cooked. This eliminates the possibility of erroneous operations, makes it easy to use the grill and oven properly, and allows each to be used with good thermal efficiency, and can be performed reliably without fear of erroneous operations.
