Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an automatic tray feeding device for a cooking range.

[Prior Art] Conventionally, this type of oven consists of a hollow oven section with an open front, a door that opens and closes the open front of the oven section, and a tray that is slidably housed in the oven section. It was pivotally attached to the open front edge of the oven section with a hinge so as to open parallel to the bottom surface of the oven section.

[Problems to be solved by the invention] However, conventional microwave ovens have problems in that it is inconvenient to take the tray in and out, and the tray cannot be pulled out sufficiently.

That is, when using the tray, open the door, insert the handle inside from the open front of the oven section, hook the handle on the edge of the tray, and pull it out from the back. The bottom of the tray was supported from below by the inside of the door. When pulling out the tray, it is more convenient to use it if it is completely pulled out, but if it is pulled out too much, the state of the tray becomes unstable, which is very dangerous if the tray is heated. For this reason, the amount by which the tray can be pulled out is determined by the width of the door, but in a thin microwave oven, there is a drawback that the tray cannot be fully pulled out because the top and bottom width of the door cannot be secured sufficiently. Further, the handle must be used to push the tray in, and the handle is also used to take it in and take it out, making it troublesome to take it in and out. Therefore, the present invention was devised in view of the above-mentioned problems of the conventional microwave oven, and its purpose is to automatically feed out the tray toward the front.

[Means for Solving the Problems] Therefore, the present invention is intended to achieve the above object, and the contents thereof will be explained below using embodiments shown in the drawings.

The feeding device according to claim 1 has an oven section 2.
A slider 4 is slidably installed inside the oven section to enter and exit from the open front surface of the oven section while holding the tray 3, and a door 5 is provided on the front edge of this slider in a substantially upright state. a biasing means 6 for biasing the slider in the direction of drawing out from the open front surface of the oven section; a releasable locking means 7 for locking the slider in the stored position in the oven section against the biasing force of the biasing means; It is characterized by comprising a braking means 8 for attenuating the urging force of the urging means.

The feeding device according to the second aspect is characterized in that a door 5 is pivotally supported on the front edge of the slider 4 so as to fall forward and open.

Claim 3: A sub-slider 47 that slides along the lower surface of the slider 4 is provided, and a door 5 is pivotally supported on the front edge of the sub-slider so as to fall forward and open, and when the door is opened toward the front, the sub-slider 47 is slidable. By retracting the slider integrally with the slider, the opened door can be stored along the lower surface of the slider in the extended state.

The feeding device according to claim 4 has an oven section 2.
A slider 4 enters and exits from the open front of the oven section while holding the tray 3, and a sub-slider 47 slides along the lower surface of this slider.
a first biasing means 6 for pivotally supporting the door 5 on the front edge of the sub-slider so that it will fall forward and open, and for feeding out the slider from the open front surface of the oven section; The first to attenuate the biasing force of
a braking means 8, and a second braking means 8 for biasing the door in the opening direction.
a releasable stopper means 53 for locking the door in the closed position against the urging force of the urging means and the sliding force of the first urging means; and the sub-slider. a third urging means 61 for urging the slider in the backward direction, and a second braking means 62 for attenuating the urging force of this urging means, so that the slider is not affected by the urging force of the first urging means. When protruding, the door is opened by the urging force of the second urging means, and after the door opens substantially parallel to the slider,
The present invention is characterized in that the sub-slider is moved backward relative to the slider by the third biasing means, and is automatically retracted along the lower surface of the slider with the door extended.

[Function] In the feeding device according to the first aspect, in order to pull out the tray 3 from the state where the tray 3 is stored in the hollow interior of the oven section 2, the locking means 7 is used.
All you have to do is release the locked state.

As a result, while the slider 4 is holding the tray, it is drawn out from the open front surface of the oven section by the urging force of the urging means 6, and at this time, the damping force of the braking means 8 acts, and the slider is moved quietly and slowly. Pay out (see No. 2, Figures 11-13). When the tray is in the extended state, food for cooking can be placed on the tray from above, or food after cooking can be taken out.

On the other hand, in order to store the tray that has been extended to the front, it is sufficient to push the slider toward the back through the door, and in this case, it is necessary to push the slider against the biasing force of the biasing means. .

In this way, when the slider is pushed in, the slider retreats while holding the tray, and when it is pushed into the storage position inside the oven section, it is locked by the locking means against the urging force of the urging means, and the tray is moved inside the oven section. (Figures 3 and 4).

In the feeding device according to the second aspect, the front side of the tray 3 can be opened by manually opening the door 5 toward the front (FIGS. 2 and 11).

In the feeding device according to claim 3, by manually pushing the door 5 after opening, the sub-slider 47 is retracted, and the door is retracted along the lower surface of the slider 4 (see FIGS. 19 and 21). .

In the feeding device according to claim 4, when the stopper means 53 is released, the door 5 in the closed state falls forward and opens due to its own weight and the urging force of the second urging means 48, and at the same time, the slider 4 is opened in the first position. The slider is fed out by the urging force of the urging means 6, and at this time, the first braking means 8 works, and the slider is quietly and slowly fed out together with the tray 3 (see FIGS. 19 and 20).

Then, when the door opens almost parallel to the slider (FIG. 22), the sliding direction of the sub-slider 47 coincides with the sliding direction of the sub-slider 47, so the sub-slider
The door is moved back relative to the slider by the biasing force of , whereby the door is automatically retracted substantially parallel to and below the lower surface of the slider (FIGS. 19 and 21). At this time, the second braking means 62 operates, the sub-slider retreats quietly and slowly, and the door is similarly retracted quietly and slowly.

On the other hand, in order to store the tray, the door stored under the slider is pulled out in parallel against the urging force of the third urging means, and then the door is pulled out by its own weight and the second
The door may be pushed up against the biasing force of the biasing means until it stands upright, and in this state, the door may be pushed in toward the back.

As a result, the slider is pushed in and retreats while holding the tray, and when the open front of the oven section is closed with the upright door, the stopper is activated and the tray is stored inside the hollow interior of the oven section. (Figures 15 and 16).

[Example] The present invention will be described below based on an example shown in the drawings.

Figures 1 to 13 show the first embodiment of the present invention. In Figure 2, 1 indicates a relatively small cooking gas range for general household use, with fish etc. A hollow oven part 2 with an open front for baking is provided, and a tray 3 is slidably accommodated in the hollow interior of the oven part 2.

As shown in FIG. 1, the feeding device for the tray 3 is slidably held in the hollow interior of the oven section 2, and a slider 4 that enters and exits from the open front surface of the oven section 2 while holding the tray 3. ,
A door 5 is provided on the front edge of the slider 4 so as to maintain a substantially upright state and opens and closes the open front surface of the oven section 2, and a door 5 is provided in the direction in which the slider 4 is drawn out from the open front surface of the oven section 2. a releasable locking means 7 that locks the slider 4 in the stored position in the oven section 2 against the urging force of the urging means 6; It is provided with a braking means 8 for damping.

The slider 4 is slidably held on a base plate 9 fixed to the bottom of the hollow interior of the oven section 2, and bearing devices 10 are arranged at various locations between the two to reduce sliding resistance. do. Note that the base plate 9 is omitted and the slider 4 is installed in the oven section 2.
may be slidably retained at the bottom of the

Each of the bearing devices 10 includes a roller 11,
A holding frame 12 that rotatably holds this roller 11
The roller 11 and the holding frame 12 are each made of plastic and assembled in advance.
Note that a ball bearing or the like may be used instead of the roller 11.

First, two types of bearing devices 10a and 10b are attached to the base plate 9, and a pair of left and right bearing devices 10a and 10a each holding two rollers 11 are attached to the bottom of the base plate 9 on the left and right sides of the front edge.
Fix the roller 11 upward (3rd and 5th
figure). Further, both left and right ends of the base plate 9 are folded upward, and the upper ends of both folded side pieces 13, 13 are further folded inward to face each other to form a total of four tongue pieces 14. A total of four bearing devices 10b each holding one roller 11 are fixed with the rollers 11 facing downward. The upper and lower bearing devices 10a and 10b are staggered in the front-rear direction, and the upper end of the roller 11 of the lower bearing device 10a and the roller 11 of the upper bearing device 10b are aligned.
The bottom edges of are slightly apart vertically when considered on the same plane.

On the other hand, two types of bearing devices 10c and 10d are attached to the slider 4, and a pair of left and right bearing devices 10c and 10c each hold two rollers 11 on the left and right sides of the rear edge at the bottom of the slider 4.
are fixed with their rollers 11 facing downward, and each roller 11 comes into sliding contact with the upper surface of the base plate 9 (FIG. 6).
In addition, both left and right ends of the slider 4 are folded back to the left and right outward to have an L-shaped cross section, and a pair of left and right bearing devices 10d, 10d holding one roller 11 is attached to the outer surface of both folded pieces 15, 15. is fixed horizontally, and each roller 11 comes into sliding contact with the inner surface of the left and right side pieces 13 of the base plate 9 (FIGS. 4 and 6).
Further, the left and right folded pieces 15 of the slider 4 are inserted into the space between the upper and lower bearing devices 10a, 10b of the base plate 9 and are held from above and below (FIG. 5).

Next, as shown in FIG. 1, a constant pressure spring 16 (Conston spring) is used as the biasing means 6 described above. Note that the spring 16 is not limited to the constant pressure spring 16, and a coil spring may be used.

The constant pressure spring 16 is always wound around the drum 17 by its spring force, and the drum 17 is rotatably held by the holder 18 at both ends. Then, the holder 18 is embedded and fixed to the rear end of the slider 4, and the free end of the constant pressure spring 16 is pulled out from under the slider 4, and fixed to the front edge of the base plate 9 along the upper surface thereof. Due to the restoring force of the constant pressure spring 16 wound around the drum 17, the slider 4 is always urged with respect to the base plate 9 in the direction of protruding from the open front surface of the oven section 2 (FIGS. 3 to 5).

The locking means 7 is provided between the inner surface of the open front edge of the oven section 2 and one side of the door 5, and a locking groove 19 is provided on the side edge of the door 5, as shown in FIG. At the same time, inside the inner surface of the open front edge of the oven section 2, as shown in FIGS. 7 to 9, a locking piece 20 that projects into the locking groove 19 is provided so as to be movable in the lateral direction. 20 is always urged in the projecting direction by the urging force of the coil spring 21. The above locking piece 20
is retracted against the biasing force of the spring 21 by pressing the push button 22 provided on the front of the range 1,
It is disengaged from the locking groove 19. In the figure, reference numeral 23 designates a unit case in which the locking piece 20, spring 21, and push button 22 are housed, each of which, except for the spring 21, is a molded plastic product, and each part is assembled to the unit case 23 in advance. Incidentally, a latch or the like may be used as the locking means 7.

As the braking means 8, as shown in FIG. 1, a piston-cylinder type air damper 24 is used. Note that the damper 24 is not limited to air, but may also be an oil or gas-injected damper.
In addition to the cylinder type, a rotary damper or governor filled with oil or the like may be used.

As shown in FIGS. 3 and 4, the damper 24 is fixed to the rear upper surface of the base plate 9 with the open end of the cylinder 25 facing forward and parallel to the sliding direction of the slider 4, and the piston 26 and the slider 4 are interconnected via a pantograph-like transmission device 27. The transmission device 27 is made up of a number of sets of equal length links 28, both large and small, which are pivotally connected by pins 29, respectively. The pin 29a at the tip is pivoted to the rear upper surface of the slider 4, here the rear end of the holder 18 of the constant pressure spring 16, and the pin 29b at the rear end is attached to the rear upper surface of the base plate 9, here the cylinder 25. At the same time, one end of the connecting rod 30 is pivotally supported on the intermediate pin 29c next to the rear end pin 29b,
The other end of the connecting rod 30 is pivoted to the piston 26 (FIGS. 3, 4, and 6).

Therefore, when the slider 4 is moved out by the restoring force of the constant pressure spring 16, the equal length link 28 extends linearly, and the distance between the front and rear pins 29 is increased, so that the piston 26 is moved through the connecting rod 30. is cylinder 2
5, and the braking force is applied at that time (10th
Figure c and Figures 11 and 12).

On the other hand, when the slider 4 is pushed in against the restoring force of the constant pressure spring 16, the equal length link 28 buckles and the distance between the front and rear pins 29 becomes shorter, so that the The piston 26 is pushed into the cylinder 25 (see Figures 3 and 4 and 10).
Figure d). In that case, the fitting groove 31 of the piston 26
Since the fitting groove 31 is wider in the front and back than the O-ring 32, the fitting groove 32 fits into the fitting groove 31.
A pair of recesses 3 provided in the fitting groove 31
3, 33, the recess 33
The air inside the cylinder 25 escapes through the damper 25, and the braking force does not work, thereby preventing the pushing force of the slider 4 from increasing due to the braking force of the damper 24 (FIGS. 10a, b, d).

The door 5, as shown in FIG. It allows you to look into it from the outside.

Next, the mounting structure of the door 5 will be explained. Although the door 5 may be fixedly installed on the front edge of the slider 4 in a substantially upright state, in this embodiment, the lower part of the door 5 is mounted in front of the slider 4. It is pivoted on the edge (Figure 2).

That is, on the inner surface of the lower frame 35 of the door 5, a pair of tongue-shaped left and right bearing pieces 37, 37 that protrude rearward are provided. , 38 are passed through the rotating shafts 39, 39 horizontally in series, so that the door 5 falls forward and opens with respect to the slider 4 (first, third, first
Figure 1).

Further, a pair of left and right cylinders 40, 40 are fixed to the front edge of the slider 4, and compression springs 41, 41 are respectively housed from the open end of each cylinder 50, and the compression springs 41 are used to close the piston 42 and the cylinder 40. Compress between the ends. Each piston 26 is then connected to the inner surface of the lower frame 35 of the door 5 via a joint 43. The joint 43 is pivotally supported at one end on the inner surface of the lower frame 35 of the door 5 and on the piston 26 at the other end. It is made to move up and down across the imaginary line l connecting the fixed shaft 43b at the end.

Therefore, due to the restoring force of the compression spring 41, the floating shaft 43a becomes stable at a lower position than the virtual line 1, and holds the door 5 in an upright position (FIG. 3).
Also, when opening the door 5, the floating shaft 43a is aligned with the virtual line l.
When it goes up too far, a clicking sensation occurs (Fig. 11).

On the other hand, in FIG. 1, 44 is a cover attached to the slider 4, on which the tray 3 is placed (FIG. 3). Further, 45 is a guide frame 45 that holds the tray 3, and this guide frame 45 holds the slider 4.
The folded edge 3' of the tray 3 is placed on the upper surface of the front edge of the tray 3 with mounting pieces 46, 46, so that the tray 3 slides together with the slider 4, and when the tray 3 hits the guide frame 45, (Figures 1, 3, and 5).

Next, the operation of the feeding device having the above configuration will be explained.

First, as shown in FIGS. 3 and 4, the oven section 2
To pull out the tray 3 stored in the microwave oven 1, the push button 22 on the front of the microwave oven 1 can be pushed. As a result, the locking piece 20 that had protruded into the locking groove 19 of the door 5 is retracted against the biasing force of the spring 21 and is disengaged from the locking groove 19 (FIG. 9). As a result, the slider 4 protrudes from the open front surface of the oven section 2 due to the restoring force of the constant pressure spring 16 that has been drawn out and trying to wrap around the drum 17 (FIG. 11).

At this time, the pantograph-shaped transmission device 27 is extended and in order to pull the piston 26 out of the cylinder 25, outside air is taken into the cylinder 25 through the orifice 25' and the movement of the piston 26 is braked (FIGS. 11 and 12). Therefore, the movement of the slider 4 by the constant pressure spring 16 is braked, and the slider 4 moves forward quietly and slowly.

Then, when the constant pressure spring 16 is almost wrapped around the drum 17, the slider 4 stops moving forward, and this position becomes the most advanced position of the slider 4, and the tray 3 is also moved forward together with the slider 4. Stand still (see Figures 2 and 11).

Next, to open the door 5, all you have to do is hold the door 5 and push it forward, and the door 5 opens to a nearly horizontal position, and also gives the user a clicking sensation when opening (second, first
1, 13).

On the other hand, in order to store the tray 3, it is sufficient to close the door 5 and then push the front side of the door 5 into the oven section 2.

First, to close the door 5, just pull the door 5 up from the bottom, and when you do so, you will feel a click just like when you open it, and if you feel this click, you can remove your hand from the door 5. , the door 5 is held upright by the movement of the floating shaft 43a of the joint 43 (see FIG. 3).

Next, when the front surface of the door 5 is pushed toward the hollow interior of the oven section 2, the slider 4 retreats together with the tray 3, and at this time, the constant pressure spring 16 wrapped around the drum 17 resists the spring force. It is then gradually fed out (Figure 3). Therefore, it is necessary to push in against the spring force of the constant pressure spring 16, and eventually the side edge of the door 5 engages with the locking piece 20, and the locking piece 20 is pushed by the side edge of the door 5. When the locking piece 20 is positioned in the locking groove 19 of the door 5, it protrudes again due to the restoring force of the spring 21, and its tip enters the locking groove 19. It plunges in and receives the restoring force of the constant pressure spring 16 (Fig. 7).

As a result, the open front surface of the oven section 2 is closed by the door 5, and the slider 4 and tray 3
is held in the storage position within the oven section 2 (FIGS. 3 and 5).

Incidentally, when the slider 4 retreats, the pantograph-shaped transmission device 27 is folded and shortened, and the piston 26 is pushed into the cylinder 25 via the connecting rod 30. The braking force doesn't work like that.

On the other hand, FIGS. 14 to 22 show other embodiments of the present invention. In this embodiment, when the tray 3 is fed out, the door 5 is automatically opened, and the door 5 is automatically placed under the slider 4. It is now stored.

In this embodiment, in addition to the slider 4, there is also a sub-slider 4 that slides along the lower surface of the slider 4.
7, and the door 5 is pivotally supported on the front edge of the sub-slider 47 so as to fall forward and open.

Note that this embodiment includes a biasing means 6 and a braking means 8 that are substantially the same as those described in the previous embodiment, and for convenience, in the description of this embodiment, the biasing means 6 described in the previous embodiment is not used. is referred to as a first biasing means 6, and the braking means 8 is referred to as a first braking means 8.

A second biasing means 48 for biasing the door 5 in the opening direction is provided between the sub-slider 47 and the door 5.
has. The biasing means 48 is composed of a compression spring 49, as shown in FIG.
9 is housed in a pair of left and right cylinders 50 and 50 fixed to the upper surface of the front edge of the sub-slider 47, respectively, and compressed between the piston 51 and the closed end of the cylinder 50 (FIGS. 17 and 22). Then, the pistons 51 are respectively connected to the inner surface of the lower frame 35 of the door 5 via pusher bars 52. The push bar 52 has one end attached to the inner surface of the lower frame 35 of the door 5, and the other end attached to the piston 2.
6, and the restoring force of the compression spring 49 always urges the door 5 in the opening direction via the push bar 52. Note that the door 5 is held in a horizontal state by the movement of the push bar 52, and the relationship is similar to the movement of the floating shaft 43a of the joint 43 described in the previous embodiment.

Further, between the door 5 and the oven section 2, there is a mechanism that locks the door 5 in the closed position against the urging force of the second urging means 48 and the force of feeding out the slider 4 by the first urging means 6. A releasable stopper means 53 is provided.
This stopper means 53 includes a stopper plate 55 having a through hole 54 inside the oven section 2.
In addition, the lower frame 35 of the door 5 has a claw 56 that fits into the through hole 54 and hooks on the rear edge.
A slide piece 57 having one side thereof is provided to be movable laterally, and the slide piece 57 is always biased laterally in the direction in which the claw 56 projects by a coil spring 58. A window portion 59 is provided on the front side of the lower frame 35 of the door 5.
Open the slide switch 6 from this window 59.
0 and slide the switch 60 sideways, the claw 5 protruding from one side of the slide piece 57
6 engages and disengages laterally from the rear edge of the through hole 54, so the door 5
When the slider 4 opens or the slider 4 moves forward, the pawl 56 comes out of the through hole 54.
Note that a latch or the like may be used as the stopper means 53.

Further, between the slider 4 and the sub-slider 47, a third urging means 61 for urging the sub-slider 47 in the backward direction with respect to the slider 4, and a second urging means 61 for attenuating the urging force of this urging means 61 are provided. A braking means 62 is provided.

The third urging means 61 is the first urging means 6
Similarly, a constant pressure spring 63 is used. Note that the spring 63 is not limited to the constant pressure spring 63, and a coil spring may be used.

The constant pressure spring 63 is always wound around the sub-drum 64 by its spring force, and the drum 64 is rotatably held by the sub-holder 65 at both ends. The sub-holder 65 is installed within the space between the lower surface of the slider 4 and the upper surface of the sub-slider 47, and is embedded in the rear end of the sub-slider 47 (FIG. 15).
Then, pull out the free end of the constant pressure spring 16 from above,
The rear end of the slider 4 is fixed along the lower surface of the slider 4, in this case just in front of the holder 18 of the first biasing means 6, and the restoring force of the constant pressure spring 63 wrapping around the sub-drum 64 causes the sub-slider 47 to be moved towards the slider 4. energized in the direction of retreating against the

As shown in FIG. 14, the left and right side pieces of the slider 4 are provided with a pair of left and right guide grooves 66, 66 extending along the sliding direction of the sub-slider 47. has a pair of left and right guide pins 6 that fit into the guide grooves 66.
7 and 67 are provided, and the guide pin 67 is in the guide groove 66.
By moving along the slider 4, the sub-slider 47 is guided to slide parallel to the lower surface of the slider 4. Moreover, the holder 18 and the sub-holder 65
By hitting the front and back, the first urging means 6 restricts the most advanced position of the slider 4, and the third urging means 61 restricts the most retracted position of the sub-slider 47 (FIG. 19).

As shown in FIG. 14, the second braking means 62 uses a piston-cylinder type sub-damper 68 similarly to the first braking means 8. Note that this damper 68 is not limited to air, but may also be an oil or gas-injected damper, or may be not only a cylinder type, but also a rotary damper or governor filled with oil or the like. .

The sub-damper 68 is fixed downward to the front lower surface of the slider 4 parallel to the sliding direction of the sub-slider 47 with the open end of its cylinder 69 facing rearward, and its sub-piston 70 is connected to a pantograph-shaped transmission device 71. It is connected to the sub-slider 47 via the slider (FIG. 16). The sub damper 68 is
Like the damper 24 of the first braking means 8, it is unidirectional, and its braking direction is made to coincide with the backward direction of the sub-slider 47.

Furthermore, the bearing device 10 does not include the bearing device 10c on the slider 4 side described in the previous embodiment, and instead includes a pair of left and right bearing devices 10e on the left and right inner surfaces of the base plate 9 with rollers 11 facing inward. , 10e are added.

Incidentally, the same components as those in the previous embodiment are given the same reference numerals, and the explanation thereof will be omitted.

Next, to explain the operation of this embodiment, when the switch 60 on the front side of the door 5 is slid sideways, the claw 56
is spaced from the rear edge of the through hole 54. Therefore, the slider 4 moves forward with the restoring force of the constant pressure spring 16, and at this time, the braking force of the damper 24 acts, causing the slider 4 to move forward.
moves forward quietly and slowly (19th and 20th)
figure).

At the same time, the closed door 5 falls forward and opens due to its own weight and the restoring force of the compression spring 49 (FIG. 22).
Then, when the door 5 opens almost parallel to the slider 4,
Since this coincides with the sliding direction of the sub-slider 47, the sub-slider 47 retreats with respect to the slider 4 by the restoring force of the constant pressure spring 63 (FIGS. 19 and 21).
Along with this, the opened door 5 is retracted parallel to and below the lower surface of the slider 4. At that time, the braking force of the sub-damper 68 works, and the sub-slider 47
slides quietly and slowly, and the door 5 is also retracted quietly and slowly.

On the other hand, in order to store the tray 3, the door 5 stored under the slider 4 is pulled out parallel to the slider 4, and then the door 5 is pushed upward against its own weight and the biasing force of the compression spring 49. The door 5 may be pulled up to an upright state, and in this state, the front surface of the door 5 may be pushed toward the oven section 2.

As a result, the slider 4 is pushed in and retreats while holding the tray 3, and the claw 56 of the slide piece 57 is placed in front of the through hole 54 in the position where the open front surface of the oven section 2 is closed with the door 5 in the upright state. The pawl 56 engages with the edge, is pushed by the front edge, and pushes back a little against the biasing force of the spring 58 into the through hole 54. When the pawl 56 passes through the through hole 54, the restoring force of the spring 58 forces the pawl 56 to push back into the through hole 54. moves forward, and the claw 56 catches the rear edge of the through hole 54, thereby receiving the restoring force of the compression spring 49 and the constant pressure spring 16.

As a result, the open front surface of the oven section 2 is closed by the door 5, and the slider 4 and the tray 3 are held in the storage position in the oven section 2 (fifteenth
Figure 16).

In this embodiment, the door 5 is automatically stored under the slider 4 when the door 5 is extended, but by omitting the second and third back movement means 48 and 61, it is possible to manually store the door 5 under the slider 4. Door 5 can also be retracted.

[Effects of the invention] Since the present invention is configured as described above,
This produces the following effects.

According to the feeding device according to the first aspect, the slider automatically feeds out the tray while holding the tray due to the releasing operation of the locking means and the urging force of the urging means, so that the tray can be taken out easily. Not only is this easy, but the urging force of the urging means can be attenuated by the braking means, so the tray can be fed out quietly and slowly, and a high-quality feeding device can be provided.

According to the feeding device according to the second aspect, the front side of the tray can be opened by opening the door toward this side, so that the usability of the tray can be further improved.

According to the feeding device according to claim 3, since the door can be manually stored under the slider,
The open door does not get in the way, and the usability of the tray can be further improved.

According to the feeding device according to the fourth aspect, the door is automatically stored under the slider when the slider is fed out, so that the trouble of opening the door can be saved.
