Abstract

PROBLEM TO BE SOLVED: To enable a heated and cooked food to be safely and easily taken out of a heating and cooking device by a method wherein there are provided a moving table having a turn-table mounted thereon and a rotating table, a slider crank mechanism and a forward or rearward guiding device are cooperatively moved when a door is opened or closed to cause the moving table and the turn table to be easily moved out of or moved into a heating chamber. SOLUTION: As a vertical open type door 2 is opened, a fixing link 12 of a slider crank mechanism fixed to the door 2 pulls a moving table 4 through an inverse moving link 13. As this moving table 4 is moved, a forward or rearward guiding device is operated, and when rollers 16a, 16b at both side surfaces of the moving table 4 are slid up from a bottom part of a slant groove of a guiding groove, the moving table 4 ascends with a turn table 6 being placed thereon so as to cause a fitted part between the turn table 6 and the rotating table 7 to be separated from each other. After this operation, the rollers 16a, 16b are restricted to perform a running only in a forward or rearward direction by a linear moving part in the guiding groove 17, and the moving table 4 is moved out of a heating chamber 1 while the turn table 6 is being placed on it and then the moving table is stopped at the outer-most location.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating / cooking device provided with a mechanism capable of moving a turntable on which an object to be heated and a moving table on which the turntable is placed into and out of a heating room in conjunction with opening and closing of a door. It is a thing.

[0002]

2. Description of the Related Art As a conventional cooking apparatus which can move a turntable into and out of a heating room, for example, FIGS.
There is something like FIG. 17 is an external perspective view, and FIG. 18 is a lateral cross-sectional view of a main part, both of which are described in JP-A-2-161214. That is, this heating and cooking device is provided with a heating chamber 10 for storing foods to be heated.
1, which has a door 1 and which can be opened and closed in front of the heating chamber 101.
02, and the moving means 111 is provided on the bottom of the heating chamber 101.
In addition to rotating the rotary moving base 103 by the drive means 107 dedicated to rotation, another independent drive means 115 moves the move means 111 in and out of the heating chamber in the front-rear direction. is there.

Then, the food is placed on the rotary moving table 103,
The door 102 is closed, and cooking is performed by a high-frequency radio wave or a heating source such as an electric heater (neither is shown). During cooking, the rotary moving table 103 is rotated by the driving means 107, and at the end of cooking, the moving table 103 can be moved into and out of the heating chamber 101 by the moving device 112 together with the moving means 111 so that the object to be heated can be easily taken out. I am doing it.

[0004]

However, in the above-described conventional heating and cooking apparatus, the moving means 111 is provided with the rotary moving table 1.
03 and the moving device 112 are incorporated, and the rotary moving table 10
3 and the moving means 111 had to be provided with a driving means. Therefore, it is necessary to provide a strong lead wire for supplying electric power to the driving means 107.
Special consideration was essential in the production.

Further, in the case of such a structure, when high frequency radio waves are used for heating energy, there is a drawback that sparks, abnormal heat generation and the like cannot be avoided.

In practical use, the moving means 111 incorporates not only the rotary moving table 103 but also the moving device 112, so that the moving means 1 may be damaged by food scraps or spills.
It is easy to interfere with the forward and backward movement of 11, and even if the part is dirty, it cannot be easily removed and washed, so the cleaning performance is poor.
In addition, it is apt to become unsanitary, and since two driving means (107 and 115) are used, the size of the apparatus becomes large and the cost becomes high. In the oven cooking, the heated moving means 111 is placed outside the heating chamber 101. Because it comes out
There were problems such as the number of exposed parts of high temperature increased and the risk of burns increased.

Further, as shown in Japanese Patent Application Laid-Open No. 5-296462, a movable table provided to be movable in and out of the heating chamber, and a movable table composed of a connecting rod, a rotating lever, a roller and the like are provided inside and outside the heating chamber. A moving means for moving in and out, a turntable on which a food is rotatably placed on the moving table, a turntable for turning the turntable at a predetermined position, and a driving means for driving the turntable. A weight detecting means for detecting the weight of the object to be heated placed on the moving table, a door open / close detecting means for detecting the open / closed state of the door, a main control means for controlling the operation of the heating means and the driving means, etc. When cooking, you can prevent uneven heating by rotating the turntable and control the cooking time based on the signal from the weight detection means.The moving table can be moved in and out of the heating chamber in conjunction with the opening and closing of the door. , There is a convenient and safe one that can prevent the occurrence of sparks without locating the lead wire in the heating chamber, but there is no means to regulate the moving direction of the moving table, and the moving table comes into contact with the heating chamber side wall when putting in and out. Fear,
In addition, the tip of the movable table or the turntable may come into contact with the inner wall surface of the door, and the operation is not smooth. Then, there is a problem that the amount of movement of the movable table does not become larger than the distance from the center line passing through the hinge center of the door to the position where the connecting rod is connected to the inner wall surface of the door.

Further, as shown in Japanese Utility Model Laid-Open No. 1-148508, a door that opens and closes the front opening of the heating chamber sideways, a turntable that rotates by placing food in the heating chamber, and this turntable. Is placed at a predetermined position for rotation, a turntable is placed on the turntable so that it can move in and out of the heating chamber, and one end is locked to the mover and the other end is locked to the door. There is a link mechanism that allows the turntable to be placed on and off the heating table in conjunction with the opening and closing of the door, allowing it to be taken in and out of the heating chamber. Similarly, there is a problem that the movement amount of the movable table does not become larger than the distance from the center line passing through the hinge center of the door to the position where the link is connected to the inner wall surface of the door.

[0009]

FIG. 3 is a model diagram for modeling the basic structure of the slider crank mechanism 5a and enabling operation analysis. The same numbers as those in FIGS. 1 and 2 indicate the same functions and the same names. However, the heating chamber 1 has a cross section and only one set of the slider crank mechanism 5a is modeled. The alphabet A indicates the length of the fixed link 12 (hereinafter abbreviated as fixed link length), and B indicates the free link. 13 is the length of C, the moving table 4 from the center of the door hinge 2a.
To the center in the horizontal direction, D is the outer diameter of the moving table 4,

In the dimension of the clearance (corresponding to the movable table initial clearance 18b, hereinafter abbreviated as initial clearance), θ indicates the opening angle with the door hinge 2a as the center, with the door 2 being closed.

Further, this model diagram is based on the time when the door 2 is closed, and the state when the door 2 is opened by θ is overwritten, and the head of the part symbol in the state when the door 2 is opened. "" Is attached. The operation is analyzed based on this model diagram, and the movement amount S that changes with the change in the opening angle of the door 2 and the gap ε between the inner wall surface of the door 2 and the tip of the moving table 4 are set.
Is shown in FIG.

However, the amount of movement on the vertical axis represents the heating chamber depth dimension as 1 and is expressed as a percentage (%), and the horizontal axis indicates the change in the vertical opening angle θ of the door 2. In this figure, + values larger than 0 indicate the inner wall surface of the door 2 and the movable table 4
It is shown that there is a gap between the tip of the slider crank mechanism 5a and the slider crank mechanism 5a.
A smaller-value indicates that the slider crank mechanism 5a is inoperable by penetrating the inner wall surface of the door 2. Also,
In the figure, ε0 is the inner wall surface of the door 2 and the movable table 4 when the door 2 is closed.
It is the amount of the initial clearance provided in advance with the tip of the door and is shown by adding to the + side of the door opening clearance ε.

As a result, when the door is opened, the opening ε is equal to the amount of the initial clearance ε0 provided in advance between the inner wall surface of the door 2 and the tip of the movable table 4 or the turntable 6, but the door 2 is opened. Accordingly, the + door gap ε gradually approaches 0, and approaches 0 most when the door opening angle θ is around 45 degrees. When the door opening angle θ is larger than that, the + side gap gradually increases, and after the door opening angle of about 60 degrees, a large + side door gap without any problem occurs.

On the other hand, the moving amount S of the movable table 4 is a smooth si.
The door opening angle θ changes to 90 degrees on the n-curve. The maximum movement amount is shown when the door opening angle θ is 90 degrees. The characteristic of this curve is that the movement amount increases relatively little when the door opening angle θ is 45 degrees or less. As described above, it is understood that the slider crank mechanism 5a operates smoothly if the physical condition of each component, for example, the door gap ε is always secured on the + side and a large movement amount can be secured.

Here, the required movement amount of the movable table 4 and the turntable 6 will be discussed. The minimum required moving amount of the moving table 4 and the turntable 6 is a lower limit value of 30% of moving amount of the food placed on the turntable 6 outside the heating chamber 1. However, it is preferable that the amount of movement exceeds 40% that the cooker can tolerate, and more desirably, the amount of movement of the movable table 4 and the turntable 6 outside the heating chamber 1 is such that the face is exposed to more than approximately half the depth of the heating chamber 1. It is more than 50%. Therefore, the specifications of the slider crank mechanism 5a that achieves this required movement amount will be described.

The relationship between the door mounting length Hy and the movement amount S is shown in FIG. However, the movement amount S on the vertical axis is the heating chamber depth dimension L standardized to 1 and expressed as a percentage (%), and the horizontal axis is the heating chamber height dimension H standardized to 1 and expressed as a percentage (%). It was done.

However, when the length A of the fixed link is 0, it corresponds to the movement amount in Japanese Utility Model Laid-Open No. 1-148508 or the prior art found in the oven toaster, and the movement amount is secured only for the door mounting length Hy or less. I can't. On the other hand, by securing the fixed link length A of at least 10% or more, it is possible to secure the movement amount in which the fixed link length A is doubled as compared with 0:00. Further, by increasing the fixed link length A by 10% or more, it is possible to easily secure a large movement amount, that is, at least the lower limit movement amount of 30%, a desirable movement amount of 40%, and a more desirable movement amount of 50% or more. it can.

Next, the proper fixed link length A of the slider crank mechanism 5a will be described. FIG. 6 shows the relationship between the fixed link length A and the movement amount S. However, the moving amount S on the vertical axis and the fixed link length A on the horizontal axis are expressed in percentage (%) by standardizing the heating chamber depth dimension L to 1. Also,
A plurality of change curves have door mounting lengths Hy of 0, 16, 32,
It shows the value when changed to 42%.

From this, the lower limit value 3 of the minimum required movement amount is obtained.
The fixed link length A that can secure 0% when the door mounting length Hy is 0 requires 28%, and the door mounting length Hy is 16
%, The fixed link length A requires 21%, and when the door mounting length Hy is 32%, the fixed link length A is 11%.
%, And when the door mounting length Hy is 42%, the fixed link length A requires 5% by extrapolation.

The fixed link length A that can secure a desired movement amount of 40% when the door mounting length Hy is 0 is 38%.
When the door mounting length Hy is 16%, the fixed link length A requires 30%, and the door mounting length Hy is 3%.
When the length is 2%, the fixed link length A requires 22%, and when the door mounting length Hy is 42%, the fixed link length A is 1%.
It turns out that 6% is required.

Further, a fixed link length A that can secure a more desirable movement amount of 50% or more when the door mounting length Hy is 0 requires 44%, and a fixed link length A when the door mounting length Hy is 16%. A requires 38%, the fixed link length A requires 30% when the door mounting length Hy is 32%, and the fixed link length A requires 25% when the door mounting length Hy is 42%. I understand that.

From this result, in order to secure a target movement amount, that is, a desirable movement amount of 50% or more, the fixed link length A needs to be long when the door mounting length Hy is small,
It is understood that the fixed link length A may be short when the door mounting length Hy is large.

Here, the upper limit value and the lower limit value of the fixed link length A will be described in detail. Hereinafter, the fixed link length A will be expressed as a percentage (%) based on the heating chamber depth dimension L. The fixed link length A must be at most 50% or less. Because the fixed link length A is 50%
With the above, the length B of the floating link becomes shorter than the fixed link length A, and the movable table 4 is lifted via the floating link 13 during the arc movement of the fixed link 12. This is because the forward / backward movement guide device 5b is caught and becomes immobile, or the swing angle β of the idle link 13 exceeds 45 degrees, and the movable table 4 cannot be smoothly moved.

When the fixed link length A is 50% or more, cooking of food or food with containers placed on the turntable 6 is completed, and the movable table 4 moves out of the heating chamber 1 to remove the food. The fixed link 12 becomes an obstacle when taking it out. Therefore, the upper limit value of 50% is set. From this, the desirable longer fixed link length A is the upper limit value of 50%.
45% or less, which does not exceed, is suitable. On the other hand, the lower limit of the fixed link length A is determined from the moving amount. The amount of movement is determined by the combination of the fixed link length A and the door mounting length Hy, but the lower limit value of the fixed link length A is at least 10% that secures 30% of the depth L of the heating chamber. is required.

Therefore, the desired fixed link length A is 10% to 45%. The more desirable length A of the fixed link is 20% to 35% which can easily secure the movement amount of 50% and does not interfere with the removal of the object to be heated.

Next, the upper limit value and the lower limit value of the door attachment length Hy of the fixed link will be described in detail. However, the door mounting length Hy is expressed as a percentage (%) based on the height of the heating chamber. The upper limit value of the fixed link door attachment length Hy needs to be equal to or less than the height at which the tip of the fixed link does not collide with the ceiling wall surface of the heating chamber opening. The door mounting length Hy at this time corresponds to 50%, and this value is the upper limit value. The lower limit of the fixed link door installation length Hy is the dimension of the part where the fixed link cannot be attached from the center of the door hinge to the bottom of the heating chamber, the half width of the fixed link, and the distance between the fixed link and the bottom of the heating chamber. Therefore, it is necessary to secure in advance 15% including a dimension of 5 mm or more for preventing sparks and abnormal heating during high frequency heating. More desirable door mounting length Hy
Is not obstructive when the door is opened 90 degrees and the object to be heated is temporarily placed on the side surface of the door heating chamber, and the movement amount can be 50% or more of the depth dimension of the heating chamber, 25% to 40%. .

Next, FIG. 7 shows the relationship between the fixed link length A and the door gap ε. However, the door gap [epsilon] on the vertical axis and the fixed link length A on the horizontal axis are expressed in percentage (%) by standardizing the depth L of the heating chamber to 1. Further, a plurality of change curves show values when the door mounting length Hy is changed to 0, 16, 32, 42%. Further, in this figure, a value of + larger than 0 indicates that there is a gap ε between the inner wall surface of the door and the tip of the moving base, and a value of − smaller than 0 penetrates the inner wall surface of the door and the slider crank mechanism. 5a shows a state in which the operation of 5a is impossible. In this figure, 6.3% is set as the initial clearance amount ε0.

From this, the initial clearance ε0 provided in advance is set.
Fixed link length A that can secure the door opening gap within +
And the door mounting length Hy is understood. That is, when the door mounting length Hy is 0, the fixed link length A that can secure the + door gap ε is a little over 50%, and the door mounting length Hy is 1
The fixed link length A that can secure the + door gap ε at 6% is 42%, and the + when the door mounting length Hy is 32%.
The fixed link length A that can secure the door gap ε is 27%, and the + door gap ε when the door mounting length Hy is 42%.
It can be seen that the fixed link length A capable of ensuring the above is 17%.

Here, a desirable setting amount of the initial clearance ε0 provided in advance will be described. When the door 2 is closed, the initial clearance amount ε0 provided between the inner wall surface of the door 2 and the tip of the moving table 4 or the turntable 6 is the heating chamber depth L, the diameter D of the moving table 4 or the turntable 6 and the moving amount. It can be decided from the relationship of S. As described above, the movement amount S of the lower limit value is 30%, the desirable movement amount is 40% or more, and the more desirable movement amount is 50% or more. From this fact, the diameter D of the movable table 4 or the turntable 6 is such that at least the tip of the movable table 4 or the turntable 6 appears outside the heating chamber 1 when moving in conjunction with opening and closing of the door, that is, the heating chamber depth dimension L.
50% is the lower limit. The initial clearance ε0 provided in advance at this time is 25%. However, this initial gap ε0
Must be 25% or less. Because the diameter D of the moving table 4 or the turntable 6 smaller than this secures a size in which a space for placing food can be secured, and the function of the slider crank mechanism 5a is satisfied, and the desired moving amount S is obtained.
Is set from 60% to 84%,
The initial clearance ε0 that can be secured at this time is 8%.
20% to 20%, and a more desirable diameter D of the moving table 4 or the turntable 6 can ensure a sufficient space for loading food, and can satisfy the function of the slider crank mechanism 5a to secure a more desirable moving amount S. 84% to 9
The initial clearance ε0 that can be secured at this time is 2.5% to 8%.

From the above results, the initial clearance ε0 provided between the inner wall surface of the door 2 and the tip of the movable table 4 or the turntable 6 when the door 2 is closed is at least based on the heating chamber depth dimension L. 25% or less, preferably 2.5% to 20%, more preferably 2.5%
To 8%.

Next, the details of one embodiment according to the specific configuration of the present invention will be described with reference to FIGS. FIG.
The same numbers as in FIG. 3 indicate the same functions and names.

One of the features of the specific configuration of one embodiment of the present invention is the vertically opening door 2 in which the door 2 opens and closes in the vertical direction around the door hinge 2a provided at the lower portion outside the opening of the heating chamber 1. The second is that the slider crank mechanism 5a of the moving means 5 is vertically provided on at least one side of the heating chamber 1 (in the figure, the state of being vertically provided on both sides is shown). The third is that the moving table 4 has a symmetric shape that is strong against thermal deformation during heating with high heat by the heating means 5, and has an annular shape with a square or circular outer shape and a center cut out in a circular shape. The size of the circular shape with the center cut out is preferably 50% to 98% of the depth dimension L of the movable table 4 in order to ensure stability when the turntable 6 is placed.

Next, the structure of the part number which has not been described will be described. Reference numeral 19 is an inclined groove having an inclination of 45 degrees or less at the center and the end of the guide grooves 17a, 17b of the forward and backward movement guide device 5b and provided with a recessed portion of 5 to 20 mm. The left central inclined groove provided at the sliding position, 19b is the left innermost inclined groove provided at the position where the roller 16b slides, and 19c is the right central inclined groove provided at the position where the roller 16c slides down. And 19d is roller 16d
Is a rightmost innermost-side slant groove provided at a position where the slides down. 20 is a side roller that is provided on both sides of the moving table 4 and prevents lateral shake when the moving table 4 moves back and forth. In particular, 20a is a left side roller that is horizontally provided on the left side surface of the moving table 4, Reference numeral 20b is a right side roller horizontally provided on the right side surface of the movable table 4.

Reference numeral 21 denotes a stopper rail which constitutes the upper side of the guide groove 17, in particular 21a denotes a left side wall stopper rail which makes a pair with the guide groove 17a, and 21b denotes a right side wall stopper rail which makes a pair with the guide groove 17b. . And, these stopper rails 21 are used especially in the roller 1 in the roller 16.
The roller running is ensured while suppressing the upward jump of 6b and 16d.

The main operation of one embodiment of the present invention will be described. Now, when the heating means 3, that is, the electric heating 3a or the high frequency heating 3b is started, first, the power button (not shown) is pressed to open the door 2 (where the movable table 4 is interlocked to move the inside and outside of the heating chamber 1). It will be moved, but it will be described in detail later, so it will be omitted.)
Put on top. Subsequently, when the cooking button (not shown) is pressed after closing the door 2, the main control means 10 receives the signal of the door “closed” from the door opening / closing detection means 9, and the main control means 10 drives the driving means 8.
The rotation of the turntable 6 is started via the turntable 7, and the heating means 3 is controlled according to the heating time to perform heating and cooking. Upon completion of heating and cooking, the main control means 10 causes the rotary table 7 to temporarily stop at a predetermined position with reference to the door direction.

Next, when the door 2 is opened, a signal from the door opening / closing detecting means 9 indicating the state of the door being “open” is sent to the main control means 1.
0 is received, and the rotation stop of the turntable 7 is held. Also,
At the same time when the door 2 is opened, the moving means 5 connected to the door 2 operates. One function of the moving means 5 is that the slider crank mechanism 5a bears this function by responding to the circular motion accompanying the opening and closing of the door 2 with a linear motion. The slider crank mechanism 5a operates simultaneously with opening and closing the door 2.

Now, when the door 2 is of the vertical opening type,
Along with the arcuate movement of the door 2 that opens vertically, the fixed link 12 fixed to the door 2 performs an arcuate movement integrally with the door 2, and the floating link 13 connected to the fixed link 12 by the link shaft 15. To the front of the heating chamber 1. at the same time,
The floating link 13 pulls the movable table 4 whose other end is connected via a connecting pin 14.

With the movement of the movable table 4, the forward / backward movement guide device 5b, which is another function of the moving means 5, operates. The forward-backward movement guide device 5b has a function of smoothly sliding the movable table 4 in the front-rear direction and a function of detaching the turntable 6 mounted on the movable table 4 from the rotary table 7. Therefore, as the movable table 4 moves, the 4
One roller 16a, 16b, 16c, 16d is the guide groove 1
7a, 17b inclined grooves 19a, 19b, 19c, 19d
As you slide up from the bottom of the
Is mounted and raised, and the fitting portion between the turntable 6 and the turntable 7 is separated. At this time, an initial gap 18 (ε0, which will be described later with this symbol) provided in advance between the tip of the movable table 4 or the turntable 6 and the inner wall surface of the door 2 and the inner wall surface according to the opening operation of the door 2 The tip of the moving table 4 and the turntable 6 moves forward while shrinking this gap ε, which is the sum of the gap generated at the opening edge of the heating chamber.

After that, the four rollers 16a, 16b, 1
6c and 16d are smoothly slid by being restricted to traveling in the front-rear direction by the linear moving portions of the guide grooves 17a and 17b, and the moving table 4 moves smoothly to the outside of the heating chamber 1 with the turntable 6 placed thereon. To do. At this time, the gap ε formed between the tip of the moving table 4 or the turntable 6 and the inner wall surface of the door 2 is reduced until the opening angle of the door 2 is 45 degrees, and the tip of the moving table 4 and the turntable 6 is reduced. When the door 1 is opened thereafter, the clearance ε is enlarged and the tip ends of the movable table 4 and the turntable 6 are advanced. When the opening of the door 2 is stopped in the state where the door 2 is most opened, the movement stops at the position where the movable table 4 is most outside. At this time, the cook can easily take out the food placed on the turntable 6 without touching the wall surface of the heating chamber 1.

When the operation of closing the door 2 again after the food is taken out, the movable table 4 is interlocked with the door 2 in the direction opposite to the "open" state of the door 2, that is, in the direction toward the inside of the heating chamber 1. Move through the moving means 5, and finally, the guide grooves 17a of the forward-backward movement guide device 5b, the inclined grooves 19a of the 17b,
19b, 19c and 19d respectively have rollers 16a, 16b and 1
6c and 16d fell and stopped. At this time, the movable table 4 is also lowered, and the turntable 6 on which it is placed is placed on the rotary table 7 while it is being lowered. As a result, the turntable 6 is re-fitted with the turntable 7, and the turntable 6 also becomes rotatable as the turntable 7 rotates. The door opening / closing detection means 9 detects that the moving table 4 and the turntable 6 are completely housed in the heating chamber 1, and sends a signal to the main control means 10 to release the rotation stop of the driving means 8. From this, the operation of the main means of the present invention in one cooking is completed.

Next, the operation of the above configuration will be described with reference to FIGS.
It will be explained in detail using 2. Now, when heating is started by electric heat 3a or high frequency radio waves 3b, first, a power button (not shown) is pressed to open the door 2 and the food or cooking container 22 to be cooked is placed on the turntable 6 inside the heating chamber 1. Put it on top. Then, the door 2 is closed and the cooking button (not shown) is pressed. As soon as the door 2 closes,
A micro switch (not shown) of the door opening / closing detection means 9 is turned on, and the main power source is turned on. In addition, a signal is sent from the microswitch to the main control means 10 to apply electric power to the motor 8a of the driving means 8 for rotation. The power of the motor 8a is transmitted to the turntable 7 and the turntable 6 via the motor shaft 8b.

Here, the rotary base 7 and the turntable 6 are fitted together by a conical male base 7a provided on the upper part of the rotary base 7 and a conical female base 6a provided on the lower surface of the turntable 6 to be integrated. Then, the turntable 7 and the turntable 6 rotate. At this time, the turntable 7 mainly receives the weight of the turntable 6 itself and the weight of the food placed on the turntable 6.
Simultaneously with the rotation of the turntable 7, the heating means 3 is operated by the main control means
Controlled by, the cooking is performed. During the heating and cooking, the main control means 10 heats the food with a predetermined heating intensity according to the type, amount, etc. of the food for a predetermined time, and when the predetermined heating time elapses, the cooking is finished.

When the heating is completed, a predetermined stop position is detected by using a reflecting plate (not shown) attached to the turntable 7. The position detection is performed by an optical sensor 21 (not shown) including a light emitting element 21a and a light receiving element 21b, and is detected at a position where the amount of light reflected from the reflector 22 changes. At this time, the optical sensor 21 sends a signal to the main control means 10 that the turntable 6 is at a predetermined position, and the power supply from the main control means 10 to the motor 8a is temporarily stopped. The motor 8a, to which the power supply from the main control means 10 has been stopped, stops rotating, and the rotating table 7 and the turntable 6 also stop rotating. At the same time, the heating means 3 receiving the signal from the main control means 10 also stops the heating of the food. At this time, with the door 2 closed, an initial clearance ε provided in advance between the tip of the movable table 4 or the turntable 6 and the inner wall surface of the door 2 is set.
0 is kept.

Next, when the door 2 is opened very slightly to take out the food from the heating chamber 1, the opening of the door 2 is detected by the micro switch of the door opening / closing detecting means 9,
The detection signal from this micro switch is the main control means 10.
Sent to Main control means 10 receiving this detection signal
Keeps stopping the power supply to the heating means 3 and holds the rotation stopped state of the motor 8a. At this time, the main control means 10 receives a signal from the optical sensor 21 and confirms that the turntable 7 is stopped at a predetermined position. This state is the state shown in FIGS. 8 and 9, and at this time, the roller 16 is stopped in the inclined surface groove 19.

First, the slider crank mechanism 5a at this time
The operation of the front-back motion guide device 5b will be described with reference to FIG.
In FIG. 10, when the door 2 is opened very slightly, the door 2
The fixed link 12 in the slider crank mechanism 5a fixed to the above is slightly moved in an arc, the center line of the fixed link 12 and the floating link 13 is slightly bent into a "F" shape, and the floating link 13 is moved. Is pulled to the door 2 side slightly. As the movable table 4 slightly moves forward, the four rollers 16 attached to the movable table 4 in the forward / backward movement guide device 5b, that is, the left central roller 16a, the left rear roller 16b, and the right central roller 16c. , Right rear roller 1
Reference numeral 6d denotes four inclined surface grooves 19 in the guide groove 17 provided on the lower portions of both inner wall surfaces of the heating chamber 1, that is, the left central side inclined groove 19
a, the leftmost incline groove 19b, the right center incline groove 19
c, the separation from the rightmost deepest side inclined groove 19d is started, and the inclined surface starts to rise. At this time, the gap ε formed between the tip of the movable table 4 or the turntable 6 and the inner wall surface of the door 2 is reduced as the opening angle of the door 2 increases.

When the door 2 is further opened, the deflection due to the arc movement of the fixed link 12 becomes a little larger, and the bending of the fixed link 12 and the floating link 13 into the “F” shape also becomes larger. Along with this, the floating link 13 pulls the movable table 4 and moves it slightly forward. Then, four rollers 16a, 16b, 16c, 16d attached to both side edges of the moving table 4
Restricts the moving direction of the movable table 4 to the front direction, and the four inclined surface grooves 19 of the two guide grooves 17a and 17b, that is, the left central inclined groove 19a, the left innermost inclined groove 19b, and the right central portion. Go up the inclined surfaces of the inclined groove 19c and the rightmost innermost inclined groove 19d. These four rollers 16a, 16b, 1
With the rise of 6c and 16d, the movable table 4 moves upward at an angle corresponding to the inclination angle of the inclined surface of the inclined groove 19.
At this time, the moving table 4 is raised so that the turntable 6 and the moving table 4 move.
When the movable table 4 rises above the clearance provided in advance, the movable table 4 starts to separate the turntable 6 from the rotary table 6. With the rise of the turntable 6
The conical female base 6a and the conical male base 7a to which the rotary base 7 is fitted are separated from each other.

Four rollers 16a, 16b, 16c, 1
4 slanted grooves 19a, 6d, respectively,
Moving up the slopes 9b, 19c and 19d, the moving table 4
Stops rising. Along with this, the turntable 6 is lifted up by a predetermined height, and the turntable 6 has a distance such that the lowermost end of the conical female support 6a of the turntable 6 does not contact the conical male support 7a of the rotary table 7. And the turntable 7 are separated. At this time, the clearance ε formed between the tip of the movable table 4 or the turntable 6 and the inner wall surface of the door 2 is equal to the door 2
The gap ε is further reduced as the opening angle of is increased. This tendency continues until the opening angle of the door 2 reaches around 45 degrees, and the tip of the movable table 4 or the turntable 6 advances.

Next, the operation of the slider crank mechanism 5a and the forward / backward movement guide device 5b when the opening angle of the door 2 is opened up to 45 degrees as shown in FIG. 11 will be described. Door 2
The fixed link 12 fixed to the door 2 makes an arc motion and rotates up to an angle of 45 degrees. Therefore, the connecting portion between the fixed link 12 and the floating link 13 is bent. As a result, the floating link 13 is pulled by the fixed link 12 to move the connected moving table 4 toward the door 2. Four rollers 16a, 16 attached to the moving table 4
b, 16c and 16d slide on the linearly moving portions of the guide grooves 17a and 17b, and the side rollers 20a and 20b act on the both side wall surfaces of the heating chamber to prevent the shake in the left and right directions, and to move the movable table 4 only in the forward direction. Regulate the movement of.

At that time, the movable table 4 or the turntable 6
The gap ε generated between the tip of the door and the inner wall surface of the door 2 is the smallest, but a small gap ε remains due to the initial gap ε0 provided beforehand, and the tip of the moving table 4 or the turntable 6 is located on the inner wall surface of the door 2. Moves forward without touching. Further, when the opening angle of the door 2 becomes 45 degrees or more, this gap ε becomes large conversely, and there is no problem that the tip of the movable table 4 or the turntable 6 contacts the inner wall surface of the door 2. As the movable table 4 moves in the forward direction, the turntable 6 mounted on the movable table 4 and the turntable 6
The food on the board moves smoothly in the direction of the door 2 and advances to a position corresponding to the opening angle of the door 2 of 45 degrees.

Next, the operation of the slider crank mechanism 5a and the forward / backward movement guide device 5b when the opening angle of the door 2 is opened up to 90 degrees as shown in FIG. 12 will be described. Door 2
The fixed link 12 fixed at 90 ° makes an arc motion of 90 degrees and becomes parallel to the bottom 11 of the heating chamber. During this time, the fixed link 12
When the ratio of the lengths of the floating link 13 and the floating link 13 is set to 1: 2, the angle formed by the connecting portion between the fixed link 12 and the floating link 13 changes from an obtuse angle to a right angle to an acute angle. The floating link 13 is pulled by the circular motion of the fixed link 12 to further move the connected moving base 4 forward.
Accordingly, the four rollers 16a, 16b, 16c,
16d and a side roller 20 (not shown) regulate the movement of the movable table 4 to the forward movement, and load the turntable 6 and the weight of the food placed on the turntable 6 into two guide grooves. It slides in 17a and 17b.

In this state, the movable table 4 projects most from the heating chamber 1. As a matter of course, the turntable 6 that has been placed on the moving table 4 and moved forward also projects most, and most of the food items placed on the turntable 6 also projects outside the heating chamber 1. From this, the food placed on the turntable 6 that protrudes the most out of the heating chamber 1 can be heated by the cook.
You can take it out safely without touching the hot wall of. Here, after taking out the food, another food may be newly placed on the moving table 4.

Next, the operation of the slider crank mechanism 5a and the forward / backward movement guide device 5b when the door 2 is closed and the movable table 4 is housed in the heating chamber 1 will be described in the reverse order of the above operation procedure. This operation proceeds in reverse from FIG. 12 to FIG. 8 in the above-mentioned explanatory diagram. That is, when the door 2 is started to be closed, the fixed link 12 of the slider crank mechanism 5a makes a circular arc motion in the clockwise direction to push the floating link 13 connected by the link shaft 15 back to the inside of the heating chamber 1. Along with the movement of the floating link 13 into the heating chamber 1, the moving table 4 connected to the floating link 13 by the connecting pin 14 is pushed by the floating link 13 and moves to the inside of the heating chamber 1 as well.

At this time, the moving table 4 or the turntable 6
The front end of the moving table 4 or the turntable 6 is located in parallel with the inner wall surface of the door 2 and the inner wall surface of the door 2 rises up when the door 2 is closed. The large gap ε between and shrinks as the door 2 closes. When the opening angle of the door 2 is around 45 degrees, these clearances ε become the smallest, and the initial clearance ε0
By providing in advance, a slight gap ε remains. When the opening angle of the door 2 exceeds 45 degrees and is further closed, these clearances ε increase little by little and return to the initial clearance ε0 with the door 2 closed. Therefore, the tip of the moving table 4 or the turntable 6 moves toward the inside of the heating chamber 1 so as to escape without hitting the inner wall surface of the door 2.

At the same time, with the movement of the movable table 4, the four rollers 16a, 16b, 16c,
16d smoothly moves in the horizontal portion of the guide grooves 17a and 17b. The slider crank mechanism 5a and the forward / backward movement guide device 5b perform the opposite operations described above until the door 2 is slightly opened after 90 degrees to 45 degrees.
Is smoothly moved to the inside of the heating chamber 1.

The final operation of closing the door 2 is such that the fixed link 12 of the slider crank mechanism 5a and the free link 13 are aligned with each other, and the four rollers 16 of the forward / backward movement guide device 5b are arranged.
a, 16b, 16c and 16d are provided in the center and the rearmost portions of the guide grooves 17a and 17b, respectively.
It ends in b, 19c and 19d. At this time, the turntable 6 returned to the inside of the heating chamber 1 on the moving table 4
Is mounted on the rotary table 7, and the conical female base 6a and the conical male base 7a are fitted to each other. This state returns to the beginning, and FIG.
This is the state shown in FIG. Here, a signal that the door 2 is completely closed is sent from the door opening / closing detection means 9 to the main control means 10 to return to the initial state of this description, and the cooking operation by the cook is resumed. It will be in a waiting state.

Next, the fixed link 1 according to the embodiment of the present invention.
The details of attaching the second door 2 to the inner wall surface will be described with reference to the drawings.

FIG. 13 is a cross-sectional view showing details of a state in which the fixed link of the heating and cooking apparatus described in the embodiment of the present invention is attached to the inner wall surface of the door. Note that FIG.
In the figure, the parts with the same numbers as those in the previous figures are the same parts. However, 2b is a center line drawn from the door hinge 2a to the center in the wall of the door 2, and 12a is a fixed link 12
12b is the center line 2 of the door hinge 2a.
It is a fixed link center line that stands vertically at a position separated by Hy from b.

Up to now, the fixed link 12 of the heating and cooking device
As shown in FIG. 13, the fixed link 12 is erected vertically on the inner wall surface of the door 2, and the body portion 12a of the fixed link 12 is fixed to the center of the straight plate as shown in FIG. Line 12b overlaps, and this fixed link center line 12
Although the configuration in which the link shaft 15 is provided on the b has been described, the essential configuration for mounting the fixed link 12 is at a position separated by Hy from the door hinge 2a with respect to the center line 2b in the door wall of the door hinge 2a. The link shaft 15 is provided at a position corresponding to the length A on the center line 12b which is vertically set. Therefore, the body portion 12a of the fixed link 12 does not necessarily have the center line 12b. The body portion 12a of the linear plate of the fixed link 12 shown in FIG. 13 is the bottom portion 1 of the heating chamber.
Since it can be sufficiently separated from 1, it is possible to prevent sparking and abnormal heating during high frequency heating, but it occupies a part of the space on the inner wall surface of the door 2 and the object to be heated is opened when the door 2 is opened horizontally. It may get in the way when temporarily placed.

Therefore, FIG. 14 is a transverse sectional view showing another embodiment in which the fixed link of the heating and cooking apparatus is attached to the inner wall surface of the door. However, 12 'is a fixed link having an L-shaped flat plate, and 12a' is a body of the fixed link 12 '. FIG. 14 shows the fixed link 1 attached to the inner wall surface of the door 2.
The shape of 2'is an L-shaped flat plate in which the body portion 12a 'of the fixed link 12' deviates from the fixed link center line 12b, and the center of the door wall of the door hinge 2a is placed on the flat plate at the tip of the fixed link 12 '. For line 2b, Hy from door hinge 2a
Length A on the center line 12b which is vertically set up at a distance
The link shaft 15 is provided at a position where the two overlap.
Therefore, the body portion 12 of the fixed link 12 'is thus
The center line 12b does not necessarily have to be on a '.
With this structure, the fixed link 12 '
However, the occupied space on the inner wall surface of the door is reduced, and it is possible to reduce the obstacle when temporarily placing the object to be heated when the door is opened horizontally.

FIG. 15 is a cross-sectional view showing yet another embodiment in which the fixed link is attached to the inner wall surface of the door. However, 12 "is a fixed link of a flat plate extended diagonally, and 12a" is a body part of the fixed link 12 ".
As can be seen from the fourth embodiment, as shown in FIG. 15, the fixed link 12 ″ is fixed to the inner wall surface of the door 2 with the center line 12 ″.
It is also possible to shift and fix to the door hinge 2a side from b, and to extend the body portion 12a ″ of the fixing link 12 ″ obliquely from here. Therefore, the body portion 12a ″ may also be a circular arc or a curved line.

FIG. 16 is a cross-sectional view showing the structure of the cooking apparatus according to the second embodiment of the present invention. The same parts as those shown in FIGS. 8 to 12 have the same parts. However, 2 "is a door having a shape in which the lower part of the door is bulged outward and the inner wall surface is recessed, and 18" is an initial clearance when the door 2 "is closed, particularly the recessed interior of the door 2". The initial gaps provided between the wall surface and the tip of the turntable 6 or the movable table 4 are 18a "and 18b".

By making the inner wall surface of the door 2 "concave, the initial clearance 18", that is, 18a ", 1
Since 8b ″ can be made large, there is an advantage that it is possible to easily secure a movement amount of 50% or more, which was difficult in the first embodiment.

The operation of the moving means 5 configured as described above is the same as that of the first embodiment in principle because the function and operation of each part are the same as the first embodiment except that the shape of the door is changed.
The description of the operation of is omitted.

[0083]

As described above, according to the heating and cooking apparatus of the present invention, the moving table on which the turntable on which the food to be heated is placed is placed, the moving means connected to the moving table, and the turntable. A slider crank mechanism and a forward-backward movement guide device for moving the moving table in and out of the heating chamber are added by providing a rotating table that fits and rotates integrally and a driving unit that rotationally drives the rotating table. At least one set of moving means is provided inside the heating chamber, and when the door is closed, an initial gap is provided in advance between the inner wall surface of the door and the tip of the moving table or turntable. In conjunction with the forward / backward movement guide device, the moving table and the turntable mounted on the moving table can be moved in and out of the heating chamber without reliably contacting the inner wall surface of the door. During cooking, the turntable and turntable rotate together to prevent food heating unevenness, and when the door is opened and closed after cooking is finished, the moving table moves in the front-back direction in conjunction with the door opening / closing operation by the moving means. The turntable mounted on the moving table can be accurately projected from the heating chamber to the outside of the heating chamber, and the cooked food on the turntable can be safely and easily placed without putting hands in the heating chamber. Since it can be taken out, the chance of touching the heated heating chamber is reduced, and burns during cooking can be prevented and safety is improved.
