BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table for placing (installing) an object to be heated in a heating chamber, which can be moved into and out of the heating chamber in conjunction with opening and closing of a door (a so-called vertical opening type door). The present invention relates to such a heating cooking device.

[0002]

2. Description of the Related Art When food is heavy or liquid, it is sometimes difficult to install the food in a heating room such as an oven or a microwave oven. In addition, when the heating chamber is at a high temperature, inserting the hand into the heating chamber itself may be dangerous.

In order to reduce such troubles and dangers, for example, as disclosed in Japanese Patent Application Laid-Open No. 2-161214, a table driven by an electric motor is placed inside and outside a heating chamber in accordance with opening and closing of a door. One that moves in and out has been proposed.

Another proposal of this type is to pull out or push in a movable table placed at the bottom of a heating chamber by opening and closing a door as in the invention of Japanese Utility Model Laid-Open No. 4-57108. Has also been proposed.

An embodiment of the present invention will be described below with reference to the drawings.

In each of the figures, a door 2 is provided at an opening 1a at the front of a heating chamber 1 for storing a food to be heated (not shown).

Here, the moving table 4 and the moving table 4
The pot 6 on the periphery of the above, the fixed link 8 for driving, and the roller 11 at the distal end of the fixed link 8 constitute a pot hanging link mechanism 5a.

Reference numerals 12 and 13 denote rollers as sliding support means for realizing the movement of the movable table 4 in the front-rear direction, respectively, and are provided at a position slightly deeper and deeper than the center of the movable table 4 in the front-rear direction. These rollers are provided on both left and right sides when the heating chamber 1 is viewed from the door 2 installation side. Reference numeral 14 denotes the bottom of the heating chamber 1.

Reference numeral 16 denotes an essential component for ensuring smooth operation of the pot-hanging link mechanism 5a according to the present invention, which is provided between the inner wall surface of the door 2 and the tip of the movable base 4 when the door 2 is closed. Is an initial gap to be provided in advance.

FIG. 3 is a model diagram for modeling the basic configuration of the pot-hanging link mechanism 5a and for enabling the operation analysis. 1 and 2 have the same functions. In FIG. 3, the symbol a of the alphabet indicates the length of the fixed link 8,
b is the vertical height of the tip bent in the shape of "F" from the axis center of the fixed link 8, D is the depth of the movable base 4, Lf is the height of the heating chamber 1, and Hy is the center of the door hinge 2a. The distance to the mounting portion of the fixed link 8 (hereinafter abbreviated as the fixed link mounting height), L is the depth dimension of the heating chamber 1, S is the amount of movement of the movable base 4 in the front-back direction, and the Greek letter β
Indicates the bending angle of the fixed link 8 bent in the shape of
ε0 is the size of a gap provided beforehand between the inner wall surface of the door and the tip of the movable table when the door is closed (hereinafter, abbreviated as the initial gap), and θ is the door hinge based on when the door 2 is closed. 2a shows the opening angle. Also, in this model diagram, the state when the door is opened by θ is overwritten based on the time when the door is closed, and the part symbol in this open state is prefixed with “'”. ing.

An operation analysis is performed based on this model diagram, and the movement amount S of the movable base 4 that changes with the change in the opening angle of the door 2 and the door gap ε between the inner wall surface of the door 2 and the tip end of the movable base 4 are analyzed. Is shown in FIG. However, the movement amount S on the vertical axis represents the depth dimension L of the heating chamber 1 as 1 and expressed as a percentage (%), and the horizontal axis represents the change in the vertical opening angle θ of the door 2. . In FIG. 4, a value of + larger than 0 indicates that there is a door gap ε between the inner wall surface of the door and the tip of the moving table, and that normal operation of the pot-hanging link mechanism 5a can be performed. However, a value of “−” smaller than 0 indicates a state in which the piercing link mechanism 5a has penetrated the inner wall surface of the door 2 and cannot operate. In addition, ε0 in FIG. 4 is the amount of an initial gap previously provided between the inner wall surface of the door and the tip of the moving table when the door is closed, and is shown by being added to the + side of the door gap ε.

Thus, the gap ε is equal to the amount of the initial gap ε0 provided in advance between the inner wall surface of the door 2 and the front end of the movable base 4 when the door 2 is closed. The positive door gap ε gradually approaches 0 with the increase of the value, and becomes the smallest (closes to 0) when the opening angle θ of the door 2 is around 45 degrees. Then, thereafter, the gap ε on the + side increases, and after the opening angle of the door 2 becomes about 60 degrees, a large door gap ε on the + side occurs without any problem.

On the other hand, the moving amount S of the moving table 4 changes on a gentle curve until the opening angle θ of the door 2 becomes 90 degrees. When the opening angle θ of the door 2 is 90 degrees, the maximum movement amount is indicated.

The characteristic of this curve is that the opening angle θ of the door 2 is 4
When the angle is 5 degrees or less, the increase of the movement amount is relatively small. Thus, if the physical condition of the components of each part, for example, the door 2 gap ε is always secured on the + side and a large moving amount can be secured, it can be understood that the pot-hanging link mechanism 5a operates smoothly.

Here, the amount of movement of the movable table 4 required during the cooking operation will be discussed. The required minimum moving amount of the moving table 4 is the moving amount 3 in which the food placed on the square plate 7 comes out of the heating chamber.
0% is the lower limit. However, it is preferable that the moving amount exceeds 40% that the cook can tolerate, and it is more preferable that the moving table 4 and the square plate 7 out of the heating chamber 1 exceed 50% of the moving amount in which the face is almost half or more. is there. Therefore, the specification of the potted link mechanism 5a that achieves the required movement amount will be described.

FIG. 5 shows the relationship between the fixed link mounting height Hy and the movement amount S. Here, the movement amount S on the vertical axis is the depth dimension L of the heating chamber 1 normalized to 1 and expressed as a percentage (%), and the horizontal axis is the height dimension Ly of the heating chamber 1 normalized to 1 and fixed. The height Hy attached to the door of the link 8 is expressed as a percentage (%).

However, when the length a of the fixed link 8 is zero, the pot 6 cannot be formed on the movable table 4 and cannot be hooked on the fixed link 8. Therefore, the fixed link 8
Must be at least 5% of the depth of the heating chamber 1. Thereby, the movement amount itself becomes possible. By setting the length a of the fixed link 8 to 5% or more, a larger movement amount, that is, at least a lower limit movement amount of 30%, but a desirable movement amount 40
%, More preferably 50% or more of the more desirable movement amount.

Next, the appropriate length a of the fixed link 8 in the pot link mechanism 5a will be described. Fixed link 8
FIG. 6 shows the relationship between the length a and the movement amount S. However, the movement amount S on the vertical axis and the fixed link length a on the horizontal axis are obtained by normalizing the depth dimension L of the heating chamber 1 to 1 and expressing it in percentage (%). In addition, a plurality of change curves indicate the door installation length Hy.
Are changed to 10, 16, 21, 26, 32, and 40%. However, when the fixed link mounting height Hy is 10%, since the dimension from the center of the door hinge 2a to the floor of the heating chamber 1 is shorter than 15% and cannot be physically formed, it is excluded from the following examination.

From the above, the lower limit value 3 of the required minimum moving amount is obtained.
When the fixed link mounting height Hy is 16%, the fixed link length a required to be 0% is 15%. When the fixed link mounting height Hy is 21%, the fixed link length a is 11%.
When the fixed link mounting height Hy is 26%, the fixed link length a requires 8%, and when the fixed link mounting height Hy is 32%, the fixed link length a is 6% by extrapolation. It turns out that it is necessary.

A fixed link length a which can secure a desired moving amount of 40% when the fixed link mounting height Hy is 16% requires 24%, and the fixed link mounting height Hy is 21%.
%, The fixed link length a requires 21%, and when the fixed link mounting height Hy is 26%, the fixed link length a
Requires 18% and the fixed height Hy is 32%
It can be seen that the fixed link length a requires 15% at the time of (1).

Further, a fixed link length a which can secure a more desirable moving amount of 50% or more when the fixed link mounting height Hy is 16% requires 33%, and is fixed when the fixed link mounting height Hy is 21%. The link length a requires 31%, and when the fixed link mounting height Hy is 26%, the fixed link length a requires 28%, and the fixed link mounting height H is required.
It can be seen that when y is 32%, the fixed link length a requires 25%.

From this result, when the fixed link mounting height Hy is small, the fixed link length a needs to be long to secure the target moving amount, that is, the more desirable moving amount of 50% or more. It can be seen that when Hy is large, the fixed link length a may be short.

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 is expressed as a percentage (%) based on the depth of the heating chamber. Now, the fixed link length a must be at most 50% or less. Because the fixed link length a is 5
If it is 0% or more, the fixed link 8 will not move due to the height of the opening of the heating chamber 1 during the arc movement of the fixed link 8. Further, when the fixed link length a is 50% or more, the fixed link 8 becomes an obstacle when taking out the object to be heated after the movable table is moved out of the heating chamber after cooking is completed.
For this reason, 50% is set as the upper limit. That is, a desirable upper limit of the fixed link 8 length a is not more than 45% and not more than 50%. On the other hand, the lower limit of the length a of the fixed link 8 is determined from the moving amount. The amount of movement is determined by a combination of the length of the fixed link 8 and the height of the fixed link 8. The lower limit of the length of the fixed link 8 is at least 5% of the length at which the amount of movement secures 30% of the depth L of the heating chamber. is necessary.

Thus, the desired length of the fixed link 8 is 5% to 45%. A more desirable length of the fixed link is 24% to 33% that can easily secure the moving amount of 50% and does not hinder the removal of the object to be heated.

Next, the upper limit value and the lower limit value of the mounting height Hy of the fixed link 8 will be described in detail. However, the mounting height Hy is expressed as a percentage (%) based on the height Lf of the heating chamber 1.

It is necessary that the upper limit of the mounting height Hy of the fixed link 8 is lower than the height at which the tip of the fixed link 8 does not hit the ceiling wall of the opening of the heating chamber. At this time, the fixed link mounting height Hy corresponds to 50%, and this value is set as the upper limit.
The lower limit of the mounting height Hy of the fixed link 8 is determined by the distance between the center of the door hinge 2 a and the bottom of the heating chamber 1.
In addition to the dimensions of the part where the bracket cannot be attached, the half width of the fixed link 8 and the space between the fixed link 8 and the bottom of the heating chamber 1 to prevent sparking or abnormal heating during high frequency heating. 15 with required dimensions of 5 mm or more
% Must be secured in advance. A more desirable fixed link mounting height Hy is a position where the object to be heated is not hindered temporarily while the door 2 is opened at 90 degrees, and the moving amount can secure 50% or more of the depth of the heating chamber. Of 16
% To 32%.

Next, the relationship between the fixed link length a and the door gap ε is shown in FIG. However, the door gap ε on the ordinate and the fixed link length a on the abscissa are expressed in percentage (%) by standardizing the depth dimension L of the heating chamber 1 to 1. Further, the plurality of change curves show that the fixed link mounting height Hy is 16%, 21
%, 26%, and 32%. Further, in FIG. 7, a + value larger than zero indicates that there is a gap ε between the inner wall surface of the door and the tip of the moving table, and a − value smaller than zero penetrates the inner wall surface of the door and hangs the pot. This shows a state where the link mechanism 5a cannot operate. In FIG. 7, the initial gap amount ε0 provided in advance is set to 5.
6% is set. From this, the relationship between the fixed link length a and the fixed link mounting height Hy at which the gap ε can be secured to + within the previously provided initial gap ε0 can be understood. That is, when the fixed link mounting height Hy is 16%, the positive gap ε
Is a little more than 50%, and the fixed link length a which can secure the + gap ε when the fixed link mounting height Hy is 21% is 37%, and the fixed link mounting height is 37%. The fixed link length a that can secure the + gap ε when Hy is 26% is 31%, and the fixed link length a that can secure the + gap ε when the fixed link mounting height Hy is 32%.
Is found to be 24%.

Here, a desired set amount of the initial gap ε0 provided in advance will be described. The amount of the initial gap ε0 provided in advance between the inner wall surface of the door 2 and the tip of the moving table 4 when the door is closed can be determined from the relationship between the depth L of the heating chamber, the depth D of the moving table 4 and the moving amount S. As described above, the lower limit of the moving amount S is 30%, the desirable moving amount is 40% or more, and the more desirable moving amount is 50% or more. From this,
The lower limit of the depth D of the movable table 4 is at least the size of the movable table 4 or the tip of the square plate 7 protruding outside the heating chamber 1 when the door is opened and closed, ie, 50% of the heating chamber depth dimension L. . The initial gap ε0 provided in advance at this time is 2%. However, the initial gap ε0 needs to be 25% or less. This is because the smaller depth D of the movable base 4 secures a size that allows a space on which food is to be loaded, and 60% to 84% that can satisfy the function of the pot hanging link mechanism 5a and secure a desired moving amount S. The initial gap ε0 provided in advance at this time can be secured at 2% to 20%.
The depth D of the square plate 7 is increased from 84% to 95%, which can secure a sufficient amount of space for placing food, and the depth of the square plate 7 can secure a more desirable movement amount S by satisfying the function of the pot-mounting link mechanism 5a. The initial gap ε0 provided in advance at this time is 2% to 8%.

From the above results, the initial gap ε0 provided between the inner wall surface of the door 2 and the tip of the movable base 4 when the door 2 is closed.
Is at least 25 with respect to the depth L of the heating chamber.
%, Preferably from 2% to 20%, more preferably from 2% to 8%.

Next, the details of one embodiment according to the specific structure of the present invention will be described with reference to FIGS.
Note that the same reference numerals as those in FIGS. 1 to 3 denote parts that perform the same functions and are parts.

One of the features of the embodiment shown in FIGS. 8 to 10 is that the door 2 is provided with a vertically open door 2 which opens and closes by rotating about a hinge 2 a provided at a lower portion outside the opening of the heating chamber 1. The second is that the pot-hanging link mechanism 5a of the moving means 5 is provided vertically on at least one side of the heating chamber 1 (in the figure, a state of being provided vertically on both sides is shown). That is. Third, the movable table 4 has a symmetrical shape that is resistant to thermal deformation during high-temperature heating by the heating means 3, and has an annular shape whose outer shape is cut out in a square shape.
The size of the square frame whose center is cut out may be 50% to 98% of the depth dimension of the movable base 4 so that the stability when the square plate 7 is placed is not impaired. desirable.

Next, the main operation of the above embodiment will be described with reference to FIGS. Now, when the heating means 3 is operated to start heating cooking, the door 2 is opened (here, the moving table 4 moves out of the heating chamber in conjunction therewith), and the food to be cooked is placed on the square plate 7. 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 detecting means 9, confirms that the start of heating is not dangerous, and then controls the heating means 3 for the set heating time to execute the heating cooking.

Next, when the set heating time has elapsed,
The main control means 10 stops the heating means 3. When the door 2 is opened, the fixed link connected to the pot 6 performs an arc motion, and applies a force directed to the outside of the heating chamber to the pot 6. Then, the movable table 4 responds with a linear motion. That is, with the circular motion of the door 2, the fixed link 8 fixed to the door 2 performs circular motion integrally with the door 2,
The moving table 4 connected to the fixed link 8 and the jar 6 is connected to the heating chamber 1.
Of the door 2 side.

Note that, with the movement of the movable table 4, the forward and backward movement guide device 5b that supports the movable table 4 also operates, and the movable table 4 is smoothly moved in the longitudinal direction. That is, as the moving table 4 moves, the four rows attached to both side edges of the moving table 4
The rails 12, 12, 13, and 13 slide in the guide groove 15 and move forward. At this time, an initial gap 16 (which is also ε0, which will be described hereinafter using this symbol) provided between the distal end of the movable base 4 and the inner wall surface of the door 2 and the door 2
In accordance with the opening operation, the tip of the movable base 4 moves forward while reducing the door gap ε.

After that, the four rollers 12 and 13 run smoothly in the guide groove 15, and the movable table 4 appears outside the heating chamber 1 with the square plate 7 placed thereon. At this time, the door gap ε generated between the distal end portion of the movable base 4 and the inner wall surface of the door 2 continues to decrease until the opening angle of the door 2 reaches 45 degrees.

Next, as shown in FIG. 9, when the door 2 is opened to 45.degree.
Explaining the operation with b, the connection between the fixed link 8 and the pot 6 is the deepest in this state. At this time, the door gap ε between the front end of the moving table 4 and the inner wall surface of the door 2 is the smallest, but since the initial gap ε0 is provided in advance, the gap ε does not become zero. Does not contact the inner wall surface of the door 2. Thereafter, when the opening angle of the door 2 becomes 45 degrees or more, the door gap ε starts to increase, and there is no danger that the front end of the moving table 4 will contact the inner wall surface of the door 2 thereafter. Fully open door 2 (90
), The result is as shown in FIG.

The operation of the pot link mechanism 5a and the forward / backward motion guide device 5b will now be described.

The fixed link 8 fixed to the door 2 makes an arc movement of 90 degrees and becomes perpendicular to the bottom 14 of the heating chamber 1. At this time, the roller 11 at the tip of the fixed link 8 is located at the lowermost edge of the pot 6. This state is the maximum projecting position of the movable base 4. Thus, the most protruding square plate 7 outside the heating chamber 1
Can be safely taken out without touching the hot wall surface of the heating chamber 1 by the cook. Here, after the food is taken out, another food may be newly placed on the moving table 4.

Next, the operations of the pot link mechanism 5a and the forward / backward movement guide device 5b when the door 2 is closed and the moving table 4 is stored in the heating chamber 1 will be described in reverse to the above operation procedure. This operation is the reverse of the operation from FIG. 8 to FIG. 10 already described. That is, door 2
When the closing is started, the fixed link 8 of the pot hanging link mechanism 5a starts the circular motion in the clockwise direction, and pushes the movable table 4 back into the heating chamber 1 via the pot 6.

At this time, as the door 2 rises, the door gap ε gradually decreases. When the opening angle of the door 2 is around 45 degrees, the door gap ε becomes the smallest, but since the initial gap ε0 is provided in advance, the door gap ε remains without colliding with the door.

When the opening angle of the door 2 exceeds 45 degrees and the door 2 is further closed, the door gap ε, which has been decreasing until now, gradually increases, and when the door 2 is completely closed, the door gap ε0 is reduced to the initial gap ε0. Return. During this time, the tip of the moving table 4 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, the center roller 12 and the innermost roller 13 of the forward and backward movement guide device 5b move smoothly in the guide groove 15 with the movement of the movable table 4. When the door 2 is fully closed, the roller 11 at the end of the fixed link 8 of the pot-hanging link mechanism 5a stops at the opening edge at the lower part of the pot 6, and the longitudinal movement guide device 5b
Rollers 12 and 13 stop at the center and the innermost part of the guide groove 15. That is, the state returns to the state of FIG.

At this point, the main control means 1
A value of 0 confirms that the door 2 is completely closed through the door open / close detecting means 9, and thereafter waits for a cooking start operation by the cook.

As described above, the tip of the fixed link 8 attached to the inner wall surface of the door 2 is inserted into the pot 6 provided downward on at least one of the left and right sides of the moving table 4 in the moving direction. In this case, the moving table 4 can be moved in and out of the heating chamber 1 in conjunction with the opening and closing operation of the door 2. The cooked food can be safely and easily taken out, and the chance of putting a hand in the heating chamber 1 where the temperature is high and there is a danger of burns is reduced, and the safety during cooking is improved.

In the above description, the case where the system between the pot 6 and the fixed link 8 is made detachable is not taken up, but even in such a case, the same effect as described above can be obtained.

[0053]

As described above, according to the cooking device of the present invention, food can be set on the moving table and taken out without putting a hand in the high-temperature heating chamber. It is now possible to safely cook with the prevention of cooking.
