Description

  The present invention relates to a grill device provided in, for example, a gas stove, an IH stove, or the like.

  As a conventional grill device, for example, as shown in FIG. 11, there is one in which a grill door 633 is installed in a drawer type (Patent Document 1). In this case, the front end portion of the grill pan 603 (mounting body) is connected to the rear surface of the grill door 633 disposed in the front opening 611 of the grill cabinet 612, and the grill door 633 is manually moved by grasping the handle 632 of the grill door by hand. The grill pan 603 is pulled out from the inside of the grill cabinet 612 together with being opened so as to be pulled out, and the grill pan 603 is accommodated in the grill cabinet 612 when the grill door 633 is pushed in and closed. The grill pan 603 may be provided with a grid on which a food such as fish is placed.

In addition, as a grill device that automatically feeds the grill pan forward, an urging means that urges a slider (mounting body) that holds the grill pan in the direction of feeding out from the front opening of the grill cabinet, and the slider in the grill cabinet And a braking means for damping the urging force of the urging means. When the lock means is unlocked, the slider holding the grill pan by the urging force of the urging means opens the front opening of the grill cabinet. In some cases, the slider is drawn out silently and slowly due to the damping force of the braking means acting at that time (Patent Document 2).
JP-A-6-105749 (FIG. 1) Japanese Utility Model Publication No. 2-62306

  However, the latter grill device that automatically and slowly unwinds the slider that holds the grill pan is not a big problem, but in the former grill device, the grill pan 603 can be put in and out by manually opening and closing the grill door 633. For this reason, when the grill door 633 is opened and closed, the food 630 may move violently on the grid or roll. That is, the inertia acts on the food 630 on the grid when the grill door 633 starts and ends, and when the grill door 633 starts and closes.

  For this reason, if the door is opened and closed vigorously, the cooked food 630 falls from the grid when the grill pan 603 is pulled out, or the cooked food 630 arranged in an orderly manner on the grid moves when the grill pan 603 is pushed in. For this reason, it was necessary to pay close attention to opening and closing the grill door 633.

  The present invention has been made in view of the above circumstances, and when opening and closing the grill door by manually opening and closing the grill door, by reducing the concern when opening and closing the door, the convenience of use in opening and closing the grill door is improved. An improved grill apparatus is realized.

(1) A grill device according to the present invention is a grill device provided with a grill door that can open and close a front opening of a grill cabinet in which a mounting body is accommodated, and the grill door is manually rotated to the front opening of the grill cabinet. In addition to providing a mounting body loading / unloading means for moving the above-mentioned mounting body in and out of the grill warehouse in conjunction with the rotation of the door at the time of opening and closing the grill door, In the opening and closing areas of the grill door when the grill door is opened and closed, there is provided a speed reduction means for slowly moving the above-mentioned mounting body in and out of these intermediate areas.

  Thereby, the moving speed of a mounting body becomes slow at the time of the movement start of a mounting body to which the food etc. which were mounted on the grid of a mounting body receive the largest inertial force, and a movement end. Therefore, it is possible to suppress a large inertia from acting on the food on the grid when the grill door is opened and closed, and when the grill door is opened and closed, and the grid door can be opened and closed without much concern. The above dish does not move violently.

(2) The speed reduction means is a gear mechanism comprising a large gear that rotates as the door of the grill door rotates, and a small gear that meshes with the large gear, and the radius of the large gear and the small gear is has a magnitude relationship of the pinion between the rotational range of the gear wheel is rotated 180 degrees range, the small gear, one end of the connecting arm for connecting to the operating point in the mounting body and out means mounting the other end When the grille door is pivotally attached and the grill door is opened and closed, the small gear is rotated in the range of 180 degrees during the rotation of the large gear, and one end of the connecting arm is 180 in parallel with the moving direction of the mounting body. It may be configured such that the operating point of the mounting body entry / exit means is moved in the moving direction of the mounting body by the other end of the connecting arm .

  According to this, when the large gear rotates within a certain range by rotating the door of the grill door, the small gear rotates within the 180 degree range, and at the same time, the connecting arm draws a 180 degree arc parallel to the moving direction of the mounting body. To be moved. For this reason, when the connecting arm is operated so as to draw a circular arc of 180 degrees, the moving distance (cos component) of the moving direction component of the mounting body is intermediate for the rotation angle. It is shorter than the moving distance. Therefore, even if the door rotation of the grill door is rotated at a constant speed, the above described placement body can be moved in and out more slowly in the movement start area and the movement end area than in the intermediate area. As a result, the moving speed of the mounting body can be slowed when the grill door is opened or closed, and when the grill door is opened or closed.

(3) The speed reducing means is a link mechanism including a long rod that rotates as the door of the grill door rotates, and a short rod that is directly or indirectly connected to the long rod, the short rod, having a relationship in which the tip of the short rod is rotated 180 degrees range between rotational range of the long rods, short rods are in a horizontal position in both closed and open state of Gurirudoa, short rod One end of a connecting arm that connects the other end to the operating point of the mounting body entry / exit means is pivotally attached to the tip of the mounting rod, and when the grill door is opened and closed, the short rod rotates while the long rod rotates. The tip of the arm is rotated in the range of 180 degrees so that one end of the connecting arm is moved so as to draw a 180-degree arc parallel to the moving direction of the mounting body, and the other end of the connecting arm The operating point is the moving direction of the mounting body It may be one that the mobile Configurations.

  Also with the speed reducing means by this link mechanism, the short rod acts in the same manner as the small gear of the gear mechanism, and the moving speed of the mounting body is reduced at the beginning and end of opening of the grill door and at the beginning and end of closing of the grill door. can do.

(4) Further, the grill door may be attached so as to open and close by rotating forwardly or horizontally.
Thus, in a state where the grill door is fully opened and the mounting body is extended, the grill door is disposed at the lower surface position of the mounting body in the forward-facing type, and the grill door is positioned at the lateral side of the mounting body in the lateral opening type. Are evacuated and arranged. Therefore, the grill door hardly goes on a business trip at the front position of the placed mounting body, and the grill door does not get in the way and the cooked food can be handled easily.

  As described above, according to the grill device according to the present invention, when the grill door is manually opened and closed and the placing body is taken in and out, the grill door is placed at the beginning and end of opening of the grill door, and at the beginning and end of closing. The moving speed of the body can be slowed, and therefore the concern when opening and closing the grill door is reduced, and the convenience of use in the opening and closing operation of the grill door can be improved.

  In addition, in the case where the grill door is mounted so as to be pivoted forward or backward and to be opened and closed, in addition, when the grill door is fully opened and the mounting body is extended, the front position of the extended mounting body In addition, since the grill door hardly goes on a business trip, the grill door does not get in the way and the cooked food can be handled easily.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
1 to 6 show a grill device 1 according to an embodiment of the present invention. As shown in FIG. 1, the grill device 1 is installed in the center of the front surface of the gas stove 100. When the grill door 4 is opened and closed forward, the grill pan 2 (mounting body) is taken in and out in conjunction with the door rotation. In this case, the moving speed of the grill pan 2 is slowed down in the movement start area (opening start / closing start) and the movement end area (opening / closing end) of the grill door 4.

Below, the structure of this grill apparatus 1 is demonstrated.
The grill device 1 has a front grille 3 having a front opening 31 for accommodating the grill pan 2, a forward-facing grill door 4 for opening and closing the front grille 3, and a door rotation when opening and closing the grill door 4. Grill pan loading / unloading means 200 (mounting body loading / unloading means, see FIGS. 2 to 6) for moving the grill pan 2 in and out of the grill cabinet 3 in conjunction with each other is provided. The grill pan 2 may have a grid g on which a food such as fish is placed.

  The grill pan entry / exit means 200 includes a pantograph mechanism 5 as a stroke expansion function unit that extends the feeding of the grill pan 2, a connecting arm 8 that transmits the rotation of the grill door 4 to the pantograph mechanism 5, and the pantograph mechanism 5. An extrusion arm 7 for connecting the grill pan 2 and a gear mechanism 6 as a speed reduction means that operates more slowly than the intermediate section in the movement start area and the movement end area of the grill door 4 (see FIGS. 2 to 6). ).

  The grill cabinet 3 is made of heat-resistant sheet metal and is formed in a rectangular shape having a front opening 31 as a whole as shown in FIG. Inside the grill cabinet 3, an inner wall plate 33 is erected in the vicinity of the left and right side plates 32, and a bottom plate 34 on which the grill pan 2 is placed is a raised bottom. The pantograph mechanism 5 is installed at the rear and the gear mechanism 6 is installed at the front between the inner wall plate 33 and the side plate 32 on the left and right sides of the grill cabinet 3. In addition, the grill pan 2 is placed in a horizontally long state on the bottom plate 34 that is the raised bottom of the grill warehouse 3 so that the short side faces the front-rear direction. A grill burner (not shown) as a heat source (not shown) is installed near the ceiling of the grill cabinet 3.

  As shown in FIG. 2, the grill pan 2 includes a rectangular container part 20 in which water is stored and a flange 21 that is provided around the outer periphery of the upper end of the container part 20. The rear flange 210 is formed in a hook shape with a hanging portion 211 extending so that the pushing arm 7 attached to the pantograph mechanism 5 is hooked. In addition, the grill pan 2 is provided with leg portions 22 </ b> F protruding downward at the four corners of the container portion 20, and provided with protrusions 22 protruding downward at the lower rear portion of the container portion 20. A protrusion 342 that protrudes upward is provided at the front portion of the bottom plate 34 of the grill cabinet 3 so as to engage with the protrusion 22 of the grill pan 2. Therefore, the grill pan 2 that slides forward on the bottom plate 34 and is fed forward is regulated so that no further extension is provided when the protrusion 22 on the lower surface is locked to the protrusion 342 on the front portion of the bottom plate 34 (FIG. 6).

  As shown in FIGS. 3 to 6, the grill door 4 is formed in a cross-sectional shape so as to protrude forward. In the grill door 4, a glass window 44 is fitted into the inclined door upper portion 43 so that the inside of the grill cabinet 3 can be seen, and a handle 45 is attached to the upper end portion thereof. In addition, the grill door 4 has shaft portions 41 provided at both ends of the door lower portion 42 pivotally supported by the lower portion of the side plate 32, and the door is pivoted forwardly in a range of 90 degrees to open and close the front opening 31 of the grill cabinet 3. I am doing so. That is, the grill door 4 fully closes the front opening 31 of the grill 3 in a vertical posture (see FIG. 3), and fully opens the front opening 31 in a horizontal posture rotated 90 degrees from this vertical posture. When the grill door 4 is fully opened, the projecting front end 4F of the grill door 4 is set to have substantially the same length as the projecting front end 2F of the extended grill pan 2 (see FIG. 6). Thereby, since the grill door 4 hardly makes a business trip to the front position of the extended grill pan 2, the grill door 4 does not get in the way and the cooked food can be handled easily.

  As shown in FIGS. 3 to 6, the pantograph mechanism 5 has first to fourth four intersections 51 to 54, and the first intersection 51 at the rearmost portion is the side plate 32 and the inner wall plate 33 of the grill 3. It is arranged so that it becomes a fixed point fixed to the front and rear and expands and contracts in the front-rear direction of the grill 3. An extrusion arm 7 (see FIG. 2) that is installed on the left and right pantograph mechanisms 5 is attached to the foremost fourth intersection 54. The push arm 7 is inserted into a guide hole 331 that is horizontally long in the left and right inner wall plates 33 and is hooked on a rear flange 210 of the grill pan 2 placed on the bottom plate 34. In addition, the other end of the connecting arm 8 connected to the gear mechanism 6 is rotatably attached to a second intersection 52 adjacent to the first intersection 51 that is a fixed point. Is an operating point that is moved by the rotation of the door when the grill door 4 is opened and closed.

  In the pantograph mechanism 5, when the second intersection 52 of the operating point is pulled and moved by the door rotation, the third intersection 53 and the fourth intersection 54 also move synchronously, so the first intersection 51 of the fixed point. With the same movement amount x as the movement amount x of the second intersection 52 with respect to, the distance between the second intersection 52 and the third intersection 53 and between the third intersection 53 and the fourth intersection 54 are also expanded simultaneously (see FIG. 6). reference.). As a result, when the pantograph mechanism 5 is viewed from the first intersection 51 of the fixed point at the foremost fourth intersection 54 to which the pushing arm 7 is attached, the movement amount is three times the movement amount x by the door rotation. Will be obtained. Therefore, according to the pantograph mechanism 5, the grill pan 2 is given a movement amount three times the movement amount x in the horizontal component of the connecting arm 8 due to the door rotation by moving the second intersection 52 as the operating point. Therefore, a sufficient feeding stroke of the grill pan 2 can be ensured. Therefore, the grill pan entrance / exit means 200 is provided with a stroke expansion function section by the pantograph mechanism 5.

  As shown in FIGS. 3 to 6, the gear mechanism 6 includes a large gear 61 that is slightly larger than a ¼ arc provided at the lower portion on the back side of the grill door 4 with the center of rotation coincident with the shaft portion 41. A half-arc small gear 62 that meshes with the large gear 61 and fixes the rotation center point 63 by the side plate 32 and the inner wall plate 33 is provided. Since the large gear 61 is fixed to the grill door 4, it is rotated at the same angle as the grill door 4.

  The radius R of the large gear 61 and the radius r of the small gear 62 have a magnitude relationship in which the small gear 62 rotates in the 180 degree range while the large gear 61 rotates in the 90 degree range (FIG. 3, See FIG. That is, the small gear 62 is rotated at a rotation angle that is twice the rotation angle of the large gear 61. The small gear 62 only needs to be rotated in the range of 180 degrees during the entire rotation of the grill door 4, and the rotation angle of the large gear 61 in the meantime may not be limited to the range of 90 degrees.

  Further, one end of a connecting arm 8 connected to the pantograph mechanism 5 is rotatably attached to the small gear 62 on a straight line that is parallel to the moving direction of the grill pan 2 and includes the rotation center point 63 of the small gear 62. It is done. Note that one end of the connecting arm 8 may not be strictly attached on a straight line including the rotation center point 63 of the small gear 62 but may be attached on a linear band in a certain range. The point is that, as will be described later, it is only necessary to drive one end of the connecting arm 8 so as to draw a 180-degree arc substantially parallel to the moving direction of the grill pan 2.

  In the gear mechanism 6, when the grill door 4 is opened and closed, the large gear 61 is rotated in the range of 90 degrees as the door is rotated, and the small gear is rotated while the large gear 61 is rotated 90 degrees. 62 is rotated in the range of 180 degrees.

  Then, one end of the connecting arm 8 connected to the small gear 62 moves so as to draw an arc 64 of 180 degrees parallel to the moving direction of the grill pan 2 (see FIG. 6), and the other end of the connecting arm 8 is Since it is rotatably attached to the pantograph mechanism 5 that is guided straight by the guide hole 331, it moves straight according to the moving direction of the grill pan 2. For this reason, in the first and last areas where one end of the connecting arm 8 moves so as to draw a 180-degree arc 64, the moving distance of the moving direction component of the grill pan 2 relative to the rotation angle relative to the intermediate area. (Cosine component of the circle) becomes shorter.

  Therefore, at the other end of the connecting arm 8 connected to the second intersection 52 which is the operating point of the pantograph mechanism 5, the movement start area (opening start / closing start) and the movement end area (opening end / closing end) when the grill door 4 is opened / closed. ), The movement amounts x1 and x3 are reduced relative to the door rotation θ (see FIGS. 3 and 6), so that the pantograph mechanism 6 in the grill pan entrance / exit means 200 is operated slowly. As a result, the grill pan 2 can be fed out more slowly in the opening start area and the opening end area of the grill door 4 than in the intermediate area. Similarly, in the closing start area and the closing end area of the grill door 4, As a result, the grill pan 2 can be pulled in more slowly.

Next, the operation of the grill device 1 will be described.
3 shows a fully closed state of the grill door 4, FIG. 4 shows a state where the grill door 4 is opened 30 degrees from the fully closed state, FIG. 5 shows a state where the grill door 4 is further opened 30 degrees from the state of FIG. FIG. 6 shows a fully open state in which the grill door 4 is further opened 30 degrees from the state of FIG. 5 and the door is rotated 90 degrees from the fully closed state.

  First, as shown in FIG. 3, the grill door 4 closes the front opening 31 of the grill cabinet 3 and the grill pan 2 is accommodated in the grill cabinet 3. Rotate 4 to open.

  As shown in FIG. 4, when the grill door 4 is opened, the large gear 61 rotates as the door rotates, and at the same time, the small gear 62 that meshes with the large gear 61 rotates. Then, the connecting arm 8 connected to the small gear 62 pulls the second intersection 52 which is the operating point of the pantograph mechanism 5 to extend the pantograph mechanism 5. When the pantograph mechanism 5 is stretched, the pusher arm 7 installed on the front thereof is moved forward along the guide hole 331 of the inner wall plate 33, and at the same time, the grill pan 2 hooked on the pusher arm 7 is moved on the bottom plate 34. Slide forward to feed forward.

  In the area where the grill door starts to open (transition from FIG. 3 to FIG. 4), the lateral movement amount x1 of the connecting arm 8 is small for the door rotation θ (= 30 degrees). Therefore, when the grill door 4 starts to open, the pantograph mechanism 5 is gradually extended little by little, so that the grill pan 2 is slowly fed out.

  Since the grill door 4 is formed in a cross-sectional shape projecting forward to secure a space on the back side, the front end portion of the grill pan 2 fed out by this space collides with the back surface of the grill door 4. The grill pan 2 can be smoothly fed out. In addition, since the grill pan 2 is placed on the bottom plate 34 of the raised bottom and is disposed higher than the shaft portion 41 that is the rotation center of the grill door 4, the protruding front end 2F of the grill pan 2 being fed out and the grill door are also provided. 4 is suppressed, and this also makes it possible to avoid a collision between the projecting front end 2F of the grill pan 2 and the rear surface of the grill door 4.

  Subsequently, as shown in FIG. 5, when the grill door 4 is further opened, the large gear 61 and the small gear 62 are rotated in conjunction with the rotation of the door, and the pantograph mechanism 5 is further extended by the connecting arm 8 so that the grill pan 2 is paid out.

  In the middle area (transition from FIG. 4 to FIG. 5) when the grill door 4 is opened / closed, the connecting arm is more for the door rotation θ (= 30 degrees) than the previous opening start area (FIG. 3 → FIG. 4). The amount of horizontal movement x2 of 8 is large. Accordingly, in this intermediate section, the pantograph mechanism 5 is stretched much, so that the grill pan 2 is fed out faster than the first opening area.

  Then, as shown in FIG. 6, when the grill door 4 is rotated 90 degrees to be in a horizontal state and completely opened, the pantograph mechanism 5 feeds almost the entire grill pan 2 out of the grill cabinet 3.

  During the opening end area of the grill door (transition from FIG. 5 to FIG. 6), the lateral direction of the connecting arm 8 is equal to the door rotation θ (= 30 degrees) as in the opening opening area (FIG. 3 to FIG. 4). The amount of movement x3 is small. Therefore, when the grill door 4 is opened, the pantograph mechanism 5 is gradually extended little by little, so that the grill pan 2 is slowly fed out.

  Then, almost the entire grill pan 2 is arranged on the grill door 4 in a horizontally opened state. As described above, this is because the movement amount x of the horizontal component of the door rotation that the pantograph mechanism 5 acts on the second intersection point 52 that is the operating point is expanded at the foremost fourth intersection point, and the stroke amount of the grill pan 2 is extended. This is because it is ensured. Therefore, since the vertical width is narrow as in a gas stove or the like, the pantograph mechanism 5 is used even when the grilling door 4 is opened and closed in a forward-facing manner, even when the feeding stroke of the grill pan 2 cannot be obtained sufficiently only by rotating the door. By this, a sufficient feeding stroke can be obtained.

  Further, the rectangular grill pan 2 is housed in the grill cabinet 3 in a horizontally long state so that the short side faces in the front-rear direction. Therefore, as long as the feeding stroke of the short side length of the grill pan 2 is secured, the grill pan 2 Almost the whole can be drawn out of the grill 3. Then, the grill pan 2 is placed in the grill box 3 in a horizontally long state, so that when the grill pan 2 is drawn out of the grill box 3, the grill pan 2 is opened forward and is arranged substantially in alignment with the horizontally long grill door 4. Can do. When the grill door 4 is fully opened, the pushing arm 7 is brought into contact with the tip of the guide hole 331, whereby the grill door 4 is held in a horizontal posture.

  When the grill pan 2 is extended, the protrusion 22 on the lower surface is locked to the protrusion 342 of the bottom plate 34, so that the grill pan 2 cannot be pulled straight any more. Since the stop is released, the grill pan 2 is removed from the grill warehouse 3 when pulled out in this inclined state.

  On the other hand, in order to accommodate the grill pan 2 in the grill cabinet 3, the grill door 4 opened in a horizontal posture is grasped by the handle 45 and lifted and rotated upward. Then, as the grill door 4 is closed, the pantograph mechanism 5 is contracted in reverse to the above, and the pushing arm 7 pulls the rear flange 210 of the grill pan 2 to accommodate the grill pan 2 in the grill cabinet 3 (FIG. 6 → FIG. 5 → FIG. 4 → FIG. 3). When the grill door 4 is closed, the closing start area (FIG. 6 → FIG. 5) and the closing end area (FIG. 4 → FIG. 3) are the opening start area of the grill door 4 (FIG. 3 → FIG. 4) and As in the open end area (FIGS. 5 to 6), the grill pan 2 is slowly pulled in for the door rotation θ.

  As described above, according to the grill device 1 of the present embodiment, the operation of the pantograph mechanism 5 in the grill pan entrance / exit means 200 is performed in the area where the grill door 4 starts moving (beginning opening / closing) and the movement end area (opening end / closing). At the end, the gear mechanism 6 including the large gear 61 and the small gear 62 is provided as a speed reduction means that operates slowly. Therefore, the movement of the grill pan 2 in which the food placed on the grid g receives the greatest inertial force. The moving speed of the grill pan 2 becomes slow at the beginning and at the end of movement.

  As a result, it is possible to suppress a large inertia from acting on the food on the grid g when the grill door 4 starts and ends, closes and closes, and opens and closes the grill door 4 without much concern. Even so, the food on the grid g does not move violently. Therefore, the concern when the door is opened and closed when the grill door 4 is manually opened and closed to put in and out the grill pan 2 is reduced, and the convenience of use in the opening and closing operation of the grill door 4 can be improved.

  Further, since the entire grill pan 2 is fed out to a position above the fully opened grill door 4 that is opened forward and held in a horizontal position, the grill door 4 may be almost on a business trip in front of the fed grill pan 2. Absent. Therefore, when the grill pan 2 is extended, the grill door 4 does not get in the way and the food on the grid g can be easily handled, and the upper end of the hot grill door 4 may be accidentally touched to cause burns. Can also be prevented.

  The present invention is not limited to the above-described embodiment, and can be appropriately changed in design without changing the scope of the invention.

(1) For example, as shown in FIG. 7, the grill door 4 may be installed in a side-opening manner. In this case, the shaft portion 41 of the grill door 4 is pivotally supported on one front portion of the side plate 32, and the gear mechanism 6 (deceleration means) and the connecting arm 8 are installed on the lower surface of the bottom plate 34 that is the raised bottom. The pantograph mechanism 5 is installed on the top. The bottom plate 34 is provided with a guide hole 341 extending straight in the moving direction of the grill pan 2, and the other end of the connecting arm 8 connected to the small gear 62 of the gear mechanism 6 through the guide hole 341 is an operating point of the pantograph mechanism 5. What is necessary is just to connect with a certain 2nd intersection 2. In this case, the inner wall plate 33 shown in FIG.

(2) The stroke expansion function part of the grill pan entrance / exit means 200 employs the above pantograph mechanism 5, but various other known means such as the link mechanism 5A shown in FIG. 8 and the rack and pinion mechanism 5B shown in FIG. It may be adopted.

  In the link mechanism 5A shown in FIG. 8, a link arm A is connected to the small gear 62 of the gear mechanism 6 instead of the connecting arm 8, and the other end of the link arm A is hooked on the rear flange 210 of the grill pan 2. A link arm B provided with an extrusion arm 7 is connected. The inner wall plate 33 is provided with an inclined second guide hole 332 that guides the coupling point between the link arm A and the link arm B. The length of the second guide hole 332 itself is set equal to the length of the guide hole 331 for guiding the push-out arm 7, that is, the feed amount of the grill pan 2. The inclination angle of the second guide hole 332 is set so that the length of the horizontal component of the second guide hole 332 is equal to the amount of movement of the horizontal component of the link arm A caused by the 180 ° rotation of the small gear 62. The Thus, according to this link mechanism 5A, the movement amount of the length of the horizontal component of the second guide hole 332 is expanded by the link arm B to the movement amount of the length of the second guide hole 332 itself, so that the grill pan 2 Therefore, it is possible to ensure a sufficient feeding stroke of the grill pan 2.

  Therefore, when the grill door 4 is opened forward, the connecting point of the link arm A and the link arm B is moved along the second guide hole 332 by rotating the door, and at the same time, the pushing arm 7 at the tip of the link arm B is moved. The grill pan 2 is moved forward along the guide hole 331, and the grill pan 2 is pushed forward by the amount of movement of the push arm 7 (FIGS. 8A and 8B). Even in this case, the grill pan 2 is moved slowly in the movement start area and the movement end area of the grill door 4 by the gear mechanism 6.

  Further, in the rack and pinion mechanism 5B shown in FIG. 9, a connecting rod C is connected to the small gear 62 of the gear mechanism 6 instead of the connecting arm 8, and two upper and lower racks 55a, 55a are connected to the other end of the connecting rod C. A pinion 56 that is engaged with and pinched by 55b is rotatably connected. The upper short rack 55 a is fixed to the inner wall plate 33 or the side plate 32. The lower long rack 55b is attached so as to be movable back and forth by the rotation of the pinion 56, and a standing bar 71 for installing the push-out arm 7 is provided at the front part.

  As a result, the lower long rack 55 b is engaged with the pinion 56, so that the lower long rack 55 b is moved equal to the amount of movement of the horizontal component of the pinion 56. Moved the same distance. That is, according to the rack and pinion mechanism 5B, the movement amount of the horizontal component of the pinion 56 is applied to the grill pan 2 by adding the rotational distance of the pinion 56 to the movement amount by the lower long rack 55b. And a sufficient stroke of the grill pan 2 can be secured.

  Accordingly, when the grill door 4 is opened forward, the pinion 56 moves while rotating by the door rotation, so that the lower long rack 55b moves by adding the rotation distance of the pinion 56 to the movement amount of the pinion 56. Then, the grill pan 2 is pushed forward through the pushing arm 7 by the amount of movement of the long rack 55b (FIGS. 9A and 9B). Even in this case, the grill pan 2 is moved slowly in the movement start area and the movement end area of the grill door 4 by the gear mechanism 6.

(3) The speed reducing means may employ other known means instead of the gear mechanism 6, and may be a link mechanism 6a shown in FIG. 10, for example. The link mechanism 6 a is composed of a long rod 61 a that rotates as the door of the grill door 4 rotates, and a short rod 62 a that is connected by the long rod 6 a and the telescopic rod 65. The short rod 62a is in a horizontal posture in both the closed state and the open state of the grill door 4, and one end of a connecting arm 8 connected to the operating point 52 of the pantograph mechanism 5 is rotatably attached to the tip thereof. Further, the short rod 62a has a relationship of rotating in a 180 degree range during the rotation range of the long rod 61a.

  According to the link mechanism 6a as the speed reducing means, when the long rod 61a is rotated within a certain range by the rotation of the grill door 4, the short rod 62a connected by the telescopic rod 65 is rotated within the 180 degree range, and at the same time. The connecting arm 8 is moved so as to draw an arc 64 of 180 degrees parallel to the moving direction of the grill pan 2 (see FIGS. 10A and 10B). Therefore, when the connecting arm 8 is operated so as to draw a 180-degree arc 64, the moving distance (cos component) of the moving direction component of the grill pan 2 is intermediate for the rotation angle. Shorter than the distance traveled. Therefore, even if the door rotation of the grill door 4 is rotated at a constant speed, the pantograph mechanism 5 can be operated more slowly in the movement start area and the movement end area than in the intermediate area. The moving speed of the grill pan 2 can be slowed when the grill door 4 starts and ends, and when the grill door 4 starts and ends.

(4) In addition, as the mounting body in the present invention, in addition to the grill pan 2, a holder for storing and mounting the various containers and the like, a base material for storing and mounting the grill pan 2 and the like may be used.
