As a result, as shown in FIGS. It is moved to the direction.
[0035]
Next, FIG. 7 shows the above-described auto lift bar 21 attached to the second horizontal wire 44 of the grill net 4 configured as described above, for example, as shown in FIGS. 3, 4 and 7. Is shown.
[0036]
That is, the auto lift bar 21 has a U-shaped cross section as a whole, for example, as shown in FIG. 7, and is made of a linear member having a wire diameter substantially the same as that of the frame portion 41 of the grill 4. Is slightly smaller than the width of the grill 4 in the left-right direction (slightly larger than twice the diameter of the frame portion) and can be fitted inside. The base ends 21a, 21a of the respective arms on the left and right sides are located at the rear from the intermediate portion OO '(see FIG. 6) in the front-rear direction of the grill 4 described above by a distance Δa. The second wire member 44 in the left-right direction is wound around and attached to both ends of the wire member 44 in the front-rear direction.
[0037]
On the other hand, at the front end side left and right frame portions, at predetermined intervals in the left and right direction, as shown in the figure, in the direction orthogonal to the left and right arm portions (the lower side in the state of being tilted forward). A pair of left and right bent portions 21b, 21b each having a U-shape slightly smaller than the width in the left-right direction of each mesh 4a projecting a predetermined size (in the state of being tilted rearward) are formed. The toaster when the door 5 is opened as described above by the pair of bent portions 21b, 21b sliding between the meshes 4a, 4a and abutting against the ribs 19, 19 on the back surface of the frame of the door 5 as described above. Of the object M to be heated.
[0038]
The length of the auto-lift bar 21 in the front-rear direction corresponds to the length between the second left-right direction wire rod 44 and the first heated object fall prevention wall 4b, for example, as is apparent from FIG. Thus, it is formed smaller by a predetermined dimension Δa than a dimension 1a / 2 which is の of the length a in the front-rear direction of the grill 4 shown in FIG.
[0039]
Then, as a result, the auto-lift bar 21 is heated and cooked in a cooking state in which the auto-lift bar 21 is tilted forward (using the auto-lift bar), for example, during toast pan heating cooking as shown by the solid line in FIG. 3 and FIG. While being moved upward in conjunction with the opening and closing operation of the opening and closing door 5 after completion, the object to be heated M placed on the grill 4 is lifted upward, while, as shown by a virtual line in FIG. In a state in which the object to be heated M on the grill 4 is in a rear end position where the object to be heated M is not hindered in a state where the object is heated rearward (when the automatic lift bar is not used).
[0040]
According to such a configuration, when the auto-lift bar 21 is tilted to the front side, and the heating cooking in which the object to be heated M is placed on the grill 4 is completed, the opening / closing door 5 is opened and the object to be heated is opened. The heating object M is taken out. At this time, the grill 4 moves forward and interlocks with the opening operation of the opening / closing door 5 to protrude from the front opening 2 a of the cooking chamber 2. The object to be heated M placed thereon is reliably lifted by ΔH above the upper surface of the grill 4 by the lift-up action of the object to be heated by the auto-lift bar 21 which is tilted forward. Therefore, only the object to be heated M can be easily and safely taken out without touching the grill 4 in a high temperature state (see FIG. 2).
[0041]
Moreover, in that case, the auto lift bar 21 pivotally supports the second left-right direction wire 44 constituting the meshes 4a, 4a,. In the state where the heating target M placed on the grill 4 is lifted upward in conjunction with the opening / closing operation of the opening / closing door 5 as described above in the state where it is tilted forward, In the state where the object to be heated M on the grill 4 is in the rearward position, it is stored and set at a rear end position which does not interfere with the object M to be heated.
[0042]
Therefore, the configuration is extremely simple, the cost is low, and the heating cooking space on the grill 4 at the time of heating cooking is not restricted at all. Therefore, the degree of freedom of the cooking menu is not hindered unlike the related art.
[0043]
In addition, the auto lift bar 21 that performs such an operation is provided with the bent portions 21b and 21b in which the rotation-side end opposite to the pivot portion is bent in a convex shape as described above, and is tilted forward. In this state, the ends of the bent portions 21b, 21b abut only on the ribs 19, 19 on the back surface of the frame of the lower opening / closing door 5, and smoothly slide in the front-rear direction. While the lift is performed smoothly upward, the tip of the bent portions 21a, 21a is directed upward in a state where the heated object M on the grill 4 is prevented from dropping rearward in a state where the bent portion 21a is tilted rearward. It is configured to function as a fall prevention wall.
[0044]
For this reason, with a very simple configuration in which only the convex bent portions 21a, 21a are provided at the rotation-side end portion, an auto-lifting action when the heated object M is taken out and a rear side of the heated object M when the heated object is cooked. It is possible to simultaneously realize two effective functions, that is, an effect of preventing the camera from dropping into the camera, and it is very convenient and easy to use.
[0045]
In this case, the second horizontal wire 44 on which the auto lift bar 21 is pivotally supported is a predetermined distance Δa behind the front-rear intermediate portion OO ′ of the grill 4 as shown in FIG. Wire.
[0046]
As described above, the left and right wire rod on which the auto lift bar 21 is pivotally supported is the second left and right wire rod 44 located a predetermined distance Δa behind the front and rear middle part OO ′ of the grill 4. In some cases, the front end of the auto lift bar 21 comes to a position suitable for lifting the front end of the heated object M, such as a toast pan, at the same time, and the length in the front-rear direction becomes compact, It is stored and set in a state where it is smoothly placed on the rear end side of the grill 4 and above the first drop-preventing wall 4b bent particularly above the grill 4 by a predetermined dimension.
[0047]
According to such a configuration, since the bent portions 21b, 21b as the second fall prevention walls are laminated on the first fall prevention wall 4b on the grill 4 side, the rotation of the auto lift bar 21 is performed. The height of the convex bent portions 21a, 21a functioning as side end portions, particularly, the final falling prevention wall of the object to be heated M becomes higher, and the function of preventing the object to be heated M from dropping during heating cooking becomes large. improves.
[0048]
Of course, in order to obtain such an effect, the winding portion serving as the rotation fulcrum may be at the intermediate portion OO 'position, but more preferably, as described above, the intermediate portion OO' position. Preferably, it is slightly behind.
[0049]
As described above, in the configuration of the present invention, since the auto-lift bar 21 for the object to be heated M can be stored without restricting the heating and cooking space of the grill 4, the usability is extremely improved. The range of menus that can be cooked is also expanded compared to conventional ones. Further, the structure is simple, no special parts are required, and it is only necessary to process one wire, so that the cost is very low.
