The user can open and close the open / close door 9 with the handle 9b.

  As shown in FIG. 3, the tray support portion 10 includes a pair of arms 13 that support the tray 8 and a rod 14. The pair of arms 13 are provided at a predetermined distance on the left and right sides of the open / close door 9. Each arm 13 extends in the front-rear direction, and the pair of arms 13 are arranged in parallel to each other. The pair of arms 13 support the tray 8 on two opposing sides (right side and left side) of the rectangle that is the planar shape of the tray 8. The tray 8 is only placed on the pair of arms 13 and is not fixed to the pair of arms 13. The front end of each arm 13 is connected to the open / close door 9 separately from the slide mechanism 4. Each arm 13 is configured to be extendable and retractable in the drawer 3 and retracting direction (front-rear direction) of the drawer body 3.

  As shown in FIGS. 4 and 6, the arm 13 includes an inner arm 17, an outer arm 18, and an adjustment member 15. The inner arm 17 and the outer arm 18 are long members each having a groove-shaped opening. The inner arm 17 and the outer arm 18 are combined in such a direction that their openings face each other. The inner arm 17 can be pulled out and stored with respect to the outer arm 18 by sliding inside the outer arm 18. With this configuration, the arm 13 expands and contracts in the front-rear direction. First, the front end of the arm 13 has been described as being connected to the open / close door 9. Specifically, as shown in FIG. 4, the front end of the inner arm 17 is connected to the open / close door 9.

  As shown in FIG. 6, the inner arm 17 has a protruding portion 17 a that protrudes outside the opening of the outer arm 18. The inner arm 17 is covered with the outer arm 18 except for the protruding portion 17a. Accordingly, the opening of the inner arm 17 is closed by the outer arm 18. As a result, the inner arm 17 and the outer arm 18 have a minute gap for allowing them to slide with each other, but the inner space of the arm 13 surrounded by the inner arm 17 and the outer arm 18 is a substantially sealed space. It has become. When the inner arm 17 is viewed in cross-section, the upper edge of the protrusion 17a forms a right angle, and the lower edge of the protrusion 17a forms an acute angle.

  As shown in FIGS. 5A and 5B, two engagement holes 18c and 18d are provided at a predetermined interval on the front side of the bottom surface of the outer arm 18 (on the side close to the open / close door). . Similarly, two engagement holes 17c and 17d are provided at a predetermined interval on the front side of the bottom surface of the inner arm 17. The distance S1 between the two engagement holes 18c, 18d of the outer arm 18 and the distance S2 between the two engagement holes 17c, 17d of the inner arm 17 are the same (S1 = S2). The adjustment member 15 engages with the engagement holes 17 c and 17 d of the inner arm 17 and the engagement holes 18 c and 18 d of the outer arm 18.

  The adjustment member 15 includes a flat plate portion 15a and two claw portions 15c and 15d that are substantially vertically raised from the flat plate portion 15a. The two claw portions 15c and 15d are provided at a predetermined interval, and the interval S3 between the two claw portions 15c and 15d is the interval S1 between the two engagement holes 18c and 18d of the outer arm 18 and the inner arm. 17 is equal to the distance S2 between the two engagement holes 17c and 17d (S3 = S1 = S2). Therefore, the adjustment member 15 is attached so that the claw portions 15 c and 15 d are inserted into the engagement holes 18 c and 18 d of the outer arm 18 or the engagement holes 17 c and 17 d of the inner arm 17.

  As shown in FIG. 4, the flat plate portion 15 a has an overhang portion 15 e that projects outward from the edge of the arm 13 in a state where the adjustment member 15 is attached to the arm 13. As will be described later, the overhanging portion 15e is a portion on which the user puts his / her finger when adjusting the pull-out amount of the arm 13. The overhanging portion 15 e may be slightly overhanging from the edge of the arm 13. In that case, the hooking width of the finger can be increased by providing the arm 13 with the meat stealing portion. The adjustment member 15 is preferably made of an elastic material such as metal that can be elastically deformed by a predetermined amount.

  Hereinafter, for convenience of explanation, in both the inner arm 17 and the outer arm 18, the engagement holes located on the front end side (side closer to the opening / closing door 9) of each arm 13 are referred to as first engagement holes 17 c and 18 c. The engagement holes positioned on the rear side (the side farther from the opening / closing door 9) than the first engagement holes 17c and 18c are referred to as second engagement holes 17d and 18d. Further, in the adjustment member 15, the claw portion located on the front end side of the arm 13 (the side close to the open / close door 9) is referred to as a first claw portion 15c, and is located behind the first claw portion 15c (from the open / close door 9). The claw portion located on the far side) is referred to as a second claw portion 15d.

The user can adjust the pull-out amount of the inner arm 17 from the outer arm 18 in stages using the adjusting member 15. Hereinafter, the adjustment method will be described.
(1) When the arm 13 is not extended As shown in FIG. 5 (A), the first engagement hole 18c of the outer arm 18 and the first engagement hole 17c of the inner arm 17 are aligned with each other at the same time. The second engagement hole 18d of the arm 18 and the second engagement hole 17d of the inner arm 17 are aligned.

  In this state, the first claw portion 15c is inserted into the engagement hole where the first engagement holes 17c, 18c of the inner arm 17 and the outer arm 18 overlap each other, and the second claw portion 15d is inserted into the inner arm 17 and The adjustment member 15 is attached to the arm 13 so that the second engagement holes 17d, 18d of the outer arm 18 are inserted into the overlapped engagement holes. Thereby, the positional relationship between the inner arm 17 and the outer arm 18 is fixed by the adjusting member 15, and the state where the arm 13 is not extended is maintained. When heating the object to be heated, the drawer body 3 is accommodated in the heating chamber 5 without extending the arm 13 as described above.

(2) When the arm 13 is extended after the drawer body 3 is pulled out from the heating chamber 5, the user hooks a finger on the overhanging portion 15 e of the adjustment member 15 and removes the adjustment member 15 once. Thereafter, as shown in FIG. 5B, the inner arm 17 is pulled out until the position of the second engagement hole 17 d of the inner arm 17 coincides with the position of the first engagement hole 18 c of the outer arm 18.

  In this state, the first claw portion 15 c is inserted into the first engagement hole 17 c of the inner arm 17, and the second claw portion 15 d is inserted into the second engagement hole 17 d of the inner arm 17 and the first engagement hole 17 c of the outer arm 18. The adjustment member 15 is attached to the arm 13 so as to be inserted into the engagement hole overlapped with the first engagement hole 18c. Thereby, the positional relationship between the inner arm 17 and the outer arm 18 is fixed by the adjustment member 15, and the state where the arm 13 is extended is maintained.

(3) When removing the inner arm 17 When the user completely removes the adjustment member 15 and releases the engagement of the adjustment member 15 to the arm 13, the user can pull out the inner arm 17 from the outer arm 18. it can. At this time, since the inner arm 17 is fixed to the opening / closing door 9, the inner arm 17 and the opening / closing door 9 can be removed together from the outer arm 18. In addition, illustration of the opening / closing door 9 is abbreviate | omitted in FIG. 5 (A), (B).

  As shown in FIG. 3, the rod 14 connects the rear ends of the pair of arms 13 (outer arms 18). At the center of the rod 14, four corners bent at substantially right angles are provided with bent portions 14 c. The bent portion 14c has a shape located obliquely below and rearward from the portion other than the bent portion 14c in a state where the rod 14 is fixed to the arm 13 (see FIGS. 1 and 2). In addition, the arm 13 includes a roller 20 that is rotatable around an axis orthogonal to the longitudinal direction of the arm 13 at the rear end of the bottom surface of the outer arm 18. When the drawer body 3 is pulled out from the cooker body 2, the arm 13 advances while the roller 20 rolls on the bottom surface of the heating chamber 5.

  As shown in FIG. 1, the cooker body 2 includes a convex portion 5 f that protrudes upward from the bottom surface 5 b of the heating chamber 5 on the front side of the bottom surface 5 b of the heating chamber 5. In addition, a roller 22 that is rotatable about an axis extending in the horizontal direction is provided above the convex portion 5f. The roller 22 is disposed at a position in contact with the upper surface of the edge 8 b of the tray 8. When the drawer body 3 is pulled out from the cooker body 2, the tray 8 is stably held on the pair of arms 13 by being pressed by the roller 22 from above. When the drawer body 3 is pulled out from the heating chamber 5, the rod 14 moves forward with the arm 13, and reaches a position where the bent portion 14c of the rod 14 engages with the convex portion 5f. At this time, since the outer arm 18 connected to the rod 14 cannot advance any further, the arm 13 is restricted from coming out of the cooker body 2.

  As shown in FIG. 7, the inner arm 17 includes a protruding portion 17g that protrudes rearward from the rear end 17e of the inner arm main body 17h. The protruding portion 17g is formed integrally with the inner arm body 17h, and has a shape in which the outer side of each fold line is bent along two fold lines that are substantially parallel to the longitudinal direction of the inner arm 17. On the other hand, the outer arm 18 includes a rear end plate 18e with which the end face of the protruding portion 17g of the inner arm 17 abuts in a state where the arm 13 is contracted to the shortest. By providing the rear end plate 18 e on the outer arm 18, the inner arm 17 is restricted from moving rearward than the outer arm 18.

  In the heating cooker 1 of the present embodiment, as shown by a solid line in FIG. 1, the front portion of the tray 8 is in the heating chamber 5 in a state where the drawer body 3 is pulled out from the heating chamber 5 without extending the arm 13. , But the rear part of the tray 8 still remains in the heating chamber 5. In this state, even if only the object to be heated can be taken out, for example, when it is desired to take out the object to be heated together with the tray 8, it is very difficult to take out. This is because if the tray 8 is to be taken out from a state where the rear portion of the tray 8 is located in the heating chamber 5, the tray 8 on which the object to be heated is placed must be tilted. Further, for example, even if an external handle for gripping the high-temperature tray 8 is to be attached, there is almost no clearance between the open / close door 9 and the tray 8, so the handle cannot be inserted.

  At this time, according to the heating cooker 1 of this embodiment, the user can extend the pair of arms 13 by one step as described in the adjustment method (2). Therefore, the open / close door 9 and the inner arm 17 can be pulled out to the position indicated by the two-dot chain line in FIG. 1 without changing the position of the outer arm 18. Specifically, the open / close door 9 and the inner arm 17 can be pulled forward by a distance L corresponding to the distance between the two engagement holes of the arm 13 (the distance between the two claw portions of the adjustment member 15) ( L = S1 = S2 = S3). In this state, since all of the tray 8 can be taken out of the heating chamber 5, the tray 8 can be lifted upward and taken out without being inclined. Alternatively, when using a handle for gripping the tray 8, a clearance is provided between the open / close door 9 and the tray 8, and the handle can be inserted. Thus, the heating cooker 1 of this embodiment can take out the tray 8 easily and becomes convenient.

  Furthermore, according to the heating cooker 1 of this embodiment, the user can remove the inner arm 17 and the open / close door 9 together from the outer arm 18 as described in the adjustment method (3) above. . Therefore, for example, even when the inner surface of the open / close door 9 is dirty, the open / close door 9 can be removed from the cooker body 2 and cleaned. Therefore, even if it is a case where the heating cooker 1 is used for a use with high use frequency, for example, the heating cooker 1 can be used cleanly.

  In the heating cooker 1 of the present embodiment, when the drawer body 3 is pulled out from the heating chamber 5, the rod 14 at the rear of the arm 13 engages with the convex portion 5 f of the heating chamber 5, and the outer arm 18 is in the cooking device body 2. It is regulated to get out of it. In this state, since the inner arm 17 and the open / close door 9 can be detached from the outer arm 18, the inner arm 17 and the open / close door 9 can be safely removed.

  The arm 13 of the present embodiment has a configuration in which the inner arm 17 is covered with the outer arm 18, and the inside of the arm 13 is a hollow sealed space. Therefore, even if the arm 13 is located inside the heating chamber 5, it is difficult for food waste and moisture to enter the internal space of the arm 13. Therefore, the smooth movement of the arm 13 is rarely hindered by these food waste and moisture. More specifically, as shown in FIG. 6, the lower end of the protruding portion 17a of the inner arm 17 forms an acute angle. With this structure, even if moisture is attached to the inner wall surface of the projecting portion 17a, the moisture flows toward the lower end of the projecting portion 17a and hardly flows to the sliding surface side between the inner arm 17 and the outer arm 18. Thereby, the malfunction resulting from the water | moisture content inside the arm 13 does not arise easily.

  Further, as described above, when the arm 13 is contracted to the shortest, the protruding portion 17g of the inner arm 17 abuts against the rear end plate 18e of the outer arm 18, and the inner arm 17 is prevented from moving further rearward. Is done. In this case, if the inner arm 17 is not provided with the projecting portion 17g, the end surface of the inner arm body 17h directly hits the rear end plate 18e of the outer arm 18 and receives an impact. As a result, the inner arm 17 is plastically deformed and friction with the outer arm 18 is increased, and the arm 13 may not be able to smoothly expand and contract. In this regard, in the present embodiment, a protruding portion 17g is provided at the rear end of the inner arm 17 so that the rear end 17e of the inner arm body 17h does not hit the rear end plate 18e of the outer arm 18. Therefore, even if the projecting portion 17g is slightly deformed by receiving an impact, the inner arm main body 17h hardly deforms. Thereby, the arm 13 can be extended and contracted smoothly.

[Second Embodiment]
In the first embodiment, an example in which the arm is expanded and contracted stepwise using the adjustment member is shown. However, it is not always necessary to use the adjustment member. For example, a gap is provided between the sliding surfaces of the inner arm and the outer arm. The arm may be expanded and contracted stepwise by changing the combination of the convex portion and the concave portion that are provided with a plurality of convex portions and a plurality of concave portions and are engaged with each other. Or it is good also as a structure which expands / contracts an arm continuously. That is, it is good also as a structure which a user can set freely the expansion-contraction amount of an arm.

[Third Embodiment]
In the first embodiment, the adjustment member can be removed, but the front end of the outer arm is made shorter than the front end of the inner arm, and the inner arm and the front end of the adjustment member are fixed, so that the arm can be removed without removing the adjustment member. May be stretched.
The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  In addition, the specific configurations such as the number, arrangement, and shape of various components constituting the heating cooker are not limited to the above embodiment, and can be changed as appropriate.
