DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-frequency heating apparatus in which a movable table on which an object to be heated is placed can be moved into and out of a heating chamber, and the practicality and safety of a cooking appliance are improved. It relates to a cooker.

[0002]

2. Description of the Related Art As a conventional high frequency heating cooker, for example, a door for opening and closing a heating chamber is provided at a lower portion of a front surface of a main body, and a movable table movable in a front-rear direction by a connecting member fixed to the door is installed in the heating chamber. Then, a rotatable turntable is placed on a moving table, and a turntable rotating means is provided.In addition to rotating the turntable by the rotating means, it can be moved in and out of the heating chamber in conjunction with the door, and when the door is opened. Has been disclosed in Japanese Unexamined Utility Model Publication No. 4-571, in which the connection with the rotating means is disengaged, and the movable table is prevented from rotating.
No. 08, and only with the door open,
With the operation button for movement, the carriage can move horizontally on the door surface and can be taken in and out of the heating chamber, food can be placed on the turntable, can be taken out after cooking, and can be moved while the carriage is moving or out of the heating chamber While the door is locked, the turntable rotates only when the door is closed.
No. 37315.

[0003] On the other hand, there is no means for moving the heating chamber into and out of the heating chamber. However, in addition to the means for rotating the turntable, the means for rotating the turntable, the means for detecting the opening and closing of the door and the means for detecting the weight are provided. Japanese Patent Application Laid-Open No. 61-119921 and the like have proposed a device capable of detecting the weight of a heated object and performing heating cooking based on the detected weight after the door is closed.

[0004]

However, in the above-mentioned high-frequency heating cooker, the movement of the object to be heated placed on the former turntable is linked to the door, so that the turntable is moved by the opening and closing speed of the door. The speed of in and out of the heating room depends on the speed of in and out, and the speed of in and out of the room is not constant. When the object to be heated is a liquid, there is a danger of burns when the object to be heated is heated to a high temperature.

In addition, since the object to be heated always comes out when the door is opened, even when it is not necessary to take out the object to be heated, such as when confirming the finish, it comes out and the temperature of the object to be heated is lowered. There was no freedom. Each time the door is opened and closed, the rotation gear of the turntable and the gear of the driving means are attached and detached, and the gears are also severely worn, and when the door is suddenly closed, the gears come into strong contact with each other. There have been various problems such as breakage and deformation of the shaft.

Also, as a practical problem, when an object to be heated is spilled into the heating chamber, the turntable is connected to the connecting member for connecting the door. Since the rear portion remains in the heating chamber, it is extremely difficult to clean not only the turntable and its cradle but also the backside and the bottom of the heating chamber. In addition, the moving distance of the turntable is determined by the length of the connecting member, and if it is necessary to extend the turntable, it is necessary to lengthen the connecting member. The turntable connecting part of the connecting member corresponding to the shaft part draws an arc locus according to the opening and closing of the door, so the turntable will move back and forth while moving up and down, so reduce the vertical movement of the turntable In this case, the connecting member cannot be made too long, and there is a problem that the forward and backward movement distance of the turntable is limited.

[0007] The movable table can be moved horizontally on the door surface by the moving operation button only in the next door opened state, and the moving table can be moved in and out of the heating chamber. There is freedom.

[0008] The latter device having the turntable rotating means, the door opening / closing detecting means and the weight detecting means has no means for moving the object to be heated into and out of the heating chamber, so that it is inconvenient to take in and out the object to be heated. In addition, when the object to be heated is spilled into the heating chamber, the last two persons do not consider the attachment and detachment of the turntable, so even if the door is opened, the rear part of the turntable and its cradle remain in the heating chamber, It was extremely difficult to clean not only the turntable and its cradle, but also its backside and the bottom of the heating chamber.

[0009]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a heating chamber, a door for opening and closing the heating chamber, and a heating means for heating an object to be heated in the heating chamber. A moving table that freely moves inside and outside the heating chamber by placing an object to be heated in the heating chamber; a driving unit that moves the moving table into and out of the heating chamber; and a rotating unit that rotates the moving table in the heating chamber. In a high-frequency heating cooker, a control device for controlling a heating means, a driving means, a rotating means, and the like, and a movement key for inputting movement information of a moving table to the control device, wherein the control device operated the movement key before starting heating. If the door is opened
Move the moving table in conjunction with it and operate the move key before starting heating.
If not done, it will not be linked with door opening,
When the door is opened and the move key is operated after
It should be moved .

[0010]

With the above-mentioned structure, the control device allows the object to be heated placed on the moving table to be moved into and out of the heating chamber by the moving table driving means provided in the high-frequency heating cooker having the moving table rotating means. By changing the operation procedure of the moving key for inputting the moving information of the moving table, the moving table is controlled so that the timing can be freely selected.
Specifically, if the move key is operated before the start of heating, the moving table is moved in conjunction with the opening of the door, and if the move key is not operated before the start of heating, the move is not linked with the opening of the door. When the door is opened during or after the end and the moving key is operated, the moving table is controlled to be moved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of a high-frequency heating cooker according to an embodiment of the present invention, and FIG. 2 is a display example of a panel display unit of the high-frequency heating cooker.

In FIG. 1, reference numeral 1 denotes a heating chamber for storing an object to be heated. Reference numeral 3 denotes a heating means (for example, a high-frequency generator or an electric heater) for generating energy for heating the object to be heated in the heating chamber 1;
It is a movable table provided so as to be able to move inside and outside. Reference numeral 5 denotes a driving means for moving the moving table 4 into and out of the heating chamber 1, and 6 denotes a moving means including the driving means 5.
Reference numeral 7 denotes rotating means for rotating the moving table 4 in the heating chamber 1 and is located below the moving table 4. The moving table 4 and the rotating means 7 are both detachably mounted on the heating chamber 1.

Reference numeral 8 denotes an open / close detecting means for detecting the open / closed state of the door 2, which can arbitrarily detect the open / close angle of the door 2. 9
Is a control device composed of a microcomputer,
The heating means 3 and the rotation means 7 are controlled according to the type of cooking,
The heating unit 3 is stopped or the movement of the movable table 4 is controlled by the driving unit 5 according to the opening / closing angle of the door 2. Reference numeral 10 denotes the control device 9, the heating chamber 1, the door 2, the heating means 3, the moving table 4,
The cooking device main body houses the driving unit 5, the moving unit 6, the rotating unit 7, and the opening / closing detecting unit 8.

Numeral 11 denotes a weight detecting means for detecting the weight of the object to be heated placed on the moving table 4. Numeral 12 denotes a rotational position detecting means for detecting the rotational position of the moving table 4. Reference numeral 13 denotes a movement key for inputting movement information of the moving table 4 to the control device 9. The control device 9 automatically presses the moving key 13 before the start of heating and opens the door 2 to automatically move the moving table 4 to the heating chamber 1. When the moving key 13 is pressed after the door 2 is opened after the heating is completed and the door 2 is opened, the moving table 4 is controlled to be moved out of the heating chamber 1.

The present invention is configured as described above. Next, the operation will be described.

When the heating of the food is started by the heating means 1 (high-frequency or electric heat energy), the control device 9 first detects the open / close state of the door 2 by means of the open / close detecting means 8 (for example, a microswitch or a position sensor) while the door 2 is open. After confirming that there is, the driving unit 5 (for example, a motor, a link cam mechanism) is drive-controlled to move the movable table 4 to the outside 1 of the heating chamber of a fixed size. After placing the object to be cooked on the moving table 4, the control device 9 controls the driving of the driving means 5 again and stores the moving table 4 in the heating chamber 1.

Subsequently, when the door 2 is closed, the control device 9 determines the weight of the object to be heated placed on the moving table 4 by a weight detecting means 11 (for example, a strain gauge for converting a distortion of a load change into an electric signal). , A piezoelectric element, etc.), and based on the weight information, drives the heating means 3 and the rotation means 7 to perform heating cooking while rotating the object to be heated to prevent uneven heating.

When the heating cooking is completed, the movable table 4 is stopped by the rotational position detecting means 12 at the same rotational position (movable position) as before the start of cooking with the door 2 as the moving direction. Next, when the door 2 is opened, the opening / closing detecting means 8 for detecting the open / closed state of the door 2 detects that the door 2 is fully opened, and if the moving key 13 is pressed before the start of heating, the control device 9 drives the driving means 5. The movable table 4 on which the object to be heated is placed under control is sent out of the heating chamber 1.

If the moving key 13 is not pressed before the heating is started, the moving table 4 does not move even if the door 2 is opened.
The moving speed of the object to be heated placed on the moving table 4 can be arbitrarily determined without being influenced by the opening / closing speed of the door 2, and a smooth operation can be obtained without falling down even in an unstable container. Various adverse effects due to the change of the opening / closing speed can be eliminated, and when the heating condition is to be checked during cooking, the moving key 13 can be removed by pressing the moving key 13 when finished. 4 can be performed. That is, by pressing the moving key 13 before or after heating or by changing the moving key 13, it is possible to select whether the moving table automatically exits or not in conjunction with the opening of the door 2, and these operations are performed by heating. Not only the operations before and after, but also the order of key operations during and during the heating and cooking operations may be changed so that the order can be freely selected.

In the moving operation of the movable table 4, the movable table 4 is moved to the movable cooking end time and the movable position relative to the door.
In the case where there is a shift in the time when the rotation of the mobile table 4 is stopped, at the same time as the end time of the heating and cooking, the shift of the mobile table 4 is determined so as to stop the rotation of the mobile table 4 at the movable position. After completion of the heating operation, or after the movable table 4 is stopped at the movable position after the completion of the heating cooking, the completion of the cooking may be notified. Note that the control device 9 counts the time during which the moving table 4 moves into and out of the heating chamber 1 and can notify a failure or an erroneous use when the moving table 4 does not return or return in a predetermined time. is there.

As shown in FIG. 2, this notification may be displayed by using a normal cooking information display unit. When the mobile base 4 is moved, an output display (for example, a bar display such as a display tube, a liquid crystal display, or a numeral) is displayed. The size of the display unit can be reduced by using the normal cooking display and the failure display or the moving display, etc., related to the movement of the moving base 4 as necessary, such as notifying the movement amount using an illustration indicating the amount. And cost reduction. At the same time, it is easier to use if information about movement information (for example, an alarm sound indicating movement failure during movement) is added.

The above is a description of an operation example in the case where an object to be heated is placed on the moving table 4 in a state where the moving table 4 is sent out of the heating chamber 1. Even when the object to be heated is placed on the moving table 4 in a state where the object to be heated is placed in the chamber 1, the moving table 4 on which the object to be heated is
It can also be sent out.

The open / close detecting means 8 for detecting the open / closed state of the door 2 can detect the open / close angle of the door 2 arbitrarily.
After stopping to ensure safety or fully opening door 2,
If the door 2 is slightly lifted up to an angle that hinders the moving operation of the moving table 4 while the moving table 4 is moving out of the heating chamber 1, the control unit 9 drives and controls the driving means 5 to move. When the table 4 is stopped or when the angle becomes a hindrance again, it is possible to easily cope with a practically possible state such as continuing the operation of re-driving the movable table 4 to the outside of the heating chamber 1. In addition, when the power is cut off or the high-frequency heating cooker is turned off, it is practical if the movable table 4 can be manually put in and out of the heating chamber 1.

When the heating chamber 1 is to be cleaned, the moving table 4 and the rotating means 7 are detachable from the heating chamber 1 so that the moving table 4 and the rotating means 7 may be removed. Since the driving means 6 of 6 is provided outside the heating chamber 1, nothing remains in the heating chamber 1 and the cleaning property is very good.

The moving table 4 is controlled not to be moved during cooking, but only when the door is opened. When the moving table 4 and the moving means 6 such as the turntable are removed from the heating chamber 1, As a configuration for controlling the driving of the driving unit 5 so as not to start, for example, if the weight detecting unit 11 is configured to detect the weight of the moving table 4 and the turntable, the presence or absence of these is determined, and the weight information is determined. If there is no such condition, it is determined that the moving table 4 or the turntable has been removed, and a control for locking the driving of the driving means 5 may be performed. When it protrudes inward, it is possible to prevent a situation in which the driving section of the driving means 5 touches a hand to cause a failure or cause an injury. If the weight of the food is too heavy and the movement of the movable table 4 is hindered, it is practical to control the driving means 5 not to be driven. As described above, the driving means 5 is driven within the predetermined weight range, and when there is no excess weight or weight information, the driving means 5 is controlled so as not to be driven, so that the operation can be performed safely, smoothly, and without failure. I can do it.

Also, when the moving table 4 is not located at the front position facing the door 2 and hinders movement, when the moving table or the turntable is removed, or when the weight of the food exceeds the hindrance, In the case where the movement is hindered due to the closing of the motor 2, the presence / absence of the hindrance is determined by the rotation position detecting means 12, the weight detecting means 11, the opening / closing detecting means 8, etc., and the driving means 5 is controlled not to be driven. At the same time, if necessary, the abnormal information of the relevant part is distinguished and notified by sound, light, letters, etc.
The characters may be reported individually or in combination as appropriate.

The heating means 3 may be cooked by adding high-frequency heating or electric heating alone or at the same time according to the menu. Particularly, in the case of oven cooking using electric heating, the heating chamber 1 is heated hot. Therefore, there is a risk of burns when touching the wall of the heating chamber 1 when taking out the object to be heated by putting a hand in the heating chamber 1 after cooking. The function of the present invention that comes out is significant in preventing the above danger.

[0028]

As described above, according to the present invention, the object to be heated placed on the movable table comes out of the heating chamber as needed, so that the object to be heated can be heated even when the heating chamber is heated to a high temperature such as oven cooking. The heating object can be easily taken out, the danger of burns can be avoided, and the heating chamber can be easily cleaned at the time of cleaning after the completion of cooking, and the potential for injury or failure during cleaning can be eliminated.
Regardless of the cooking menu, when the object to be heated is heavy or when the high-frequency heating cooker is installed at a high position, the object to be heated can be taken in and out of the heating chamber, so it is easy to take and very convenient and practical. The effect is high.

Further, since the apparatus is provided with driving means for moving the moving table, rotating means for the moving table, these control devices, and moving keys for inputting the moving information of the moving table to the control device, it is possible to move the moving object into and out of the heating chamber. In conjunction with the moving operation and the rotating operation to prevent uneven heating, a series of automation in the cooking operation such as the heating operation and the moving operation of the object to be heated to and from the heating room can be performed. By simply changing the procedure, you can select the manual operation by operating the movement key by interlocking or not interlocking with the door opening and selecting it as necessary, so the moving speed of the heated object does not depend on the opening and closing speed of the door It can be determined arbitrarily, smooth operation can be obtained without falling even in unstable containers, and various adverse effects due to changes in door opening and closing speed can be eliminated. The high-frequency heating cooker is safe, practical, and convenient, as it can be used to check the heating condition during cooking, etc. Can be provided.
