Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables a movable table on which an object to be heated is placed to be moved in and out of a heating chamber, and its driving means is provided outside the heating chamber to enhance cleaning performance. The present invention relates to a heating cooker with improved practicality and safety as a cooker.

[0002]

2. Description of the Related Art As a conventional heating cooker, for example, a door for opening and closing a heating chamber is provided at a lower part of a front surface of a main body, and a movable table movable in the front-rear direction is installed in the heating chamber by a connecting member fixed to the door. , A rotatable turntable is placed on a moving table, and equipped with a turntable rotating means. The rotating means rotates the turntable, and it can be moved inside and outside the heating room in conjunction with the door. The connection with the rotating means is disengaged so that the movable table is prevented from rotating so that the object to be heated can be easily installed and taken out by the operation of the Japanese Utility Model Laid-Open No. 4-57108, and only by the operation button for moving only when the door is open. The table can move the door surface horizontally and put it in and out of the heating chamber, put food on the turntable,
It can be taken out after cooking, and the door is locked while the moving table is moving or outside the heating room, and the turntable rotates only when the door is closed.
No. 315 is proposed.

On the other hand, there is no means for moving the heating chamber into and out of the heating chamber, but it is provided with a turntable rotating means, and the turntable is rotated by the rotating means. In addition, a door open / close detecting means and a weight detecting means are provided so that the door is opened. Japanese Patent Application Laid-Open No. 61-119921 proposes 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-described heating cooker, since the load of the object to be heated placed on the former turntable is received by the bottom surface of the heating chamber, the weight of the object to be heated is detected. Cannot be done, which is a disadvantage for automation of cooking. Also, because it is linked to the door, the speed at which the turntable appears and disappears inside and outside the heating room depends on the opening and closing speed of the door, and the appearing and disappearing speed is not constant. If the object to be heated is hot, for example, if the object to be heated falls down due to the impact when the door is opened, or if the object to be heated is a liquid, there is a risk of burns. There was a nature.

Moreover, since the object to be heated always comes out when the door is opened, even if it is not necessary to take out the object to be heated such as checking the finish, the temperature of the object to be heated is lowered by coming out, and the taking-out / removing option is selected. There was a problem that there was no freedom. Each time the door is opened and closed, the gear for rotation of the turntable and the gear of the drive means are attached and detached.Therefore, the gears are severely worn, and when the doors are suddenly closed, the gears hit each other strongly. There were various problems such as breakage and deformation of the shaft.

In addition, as a practical problem, when an object to be heated is spilled into the heating chamber, the turntable is connected by the connecting member for connecting the door, so that even if the door is opened, the turntable and its cradle are connected. Since the rear part remains in the heating chamber, it is extremely difficult to clean not only the turntable and its cradle but also the back side and the bottom of the heating chamber. Moreover, the moving distance of the turntable is determined by the length of the connecting member, and if you try to put out a lot of it, you need to lengthen the connecting member. In this case, the connecting member becomes an obstacle when putting in and out the object to be heated, and for opening and closing the door. The turntable connecting part of the connecting member draws an arc locus corresponding to the opening and closing of the door, so the turntable moves back and forth while moving up and down, so try to reduce the vertical movement of the turntable. In that case, there is a problem in that the connecting member cannot be made very long and the front-back movement distance of the turntable is limited.

Even when the moving table is used to move the moving table horizontally to move the door surface into and out of the heating chamber only in the next door open state, it is convenient to move the object to be heated in and out of the heating chamber, and it is also possible to select it. There is freedom, but the weight of the object to be heated cannot be detected, which is a disadvantage for automation of cooking. In addition, the former two having means for moving these heated objects into and out of the heating chamber have different rotation stop positions before and after heating and cooking of the heated objects placed on the turntable, so that the movement before heating and cooking is different. Even if the time was stable, it stopped at an unstable position after cooking, and if it moved after cooking, the object to be heated might fall down.

The latter one provided with the rotating means of the turntable, the door opening / closing detecting means and the weight detecting means can detect the weight of the object to be heated and is advantageous for the automation of cooking. It is inconvenient to put in and take out the object to be heated because there is no means to move it to. Also, since the latter two do not consider attaching and detaching the turntable when the object to be heated is spilled into the heating chamber, the rear part of the turntable and its cradle remains in the heating chamber even if the door is opened. It was extremely difficult to clean not only the turntable and its cradle but also the back side and the bottom of the heating chamber.

[0009]

The present invention has been made to solve the above-mentioned problems, and includes a heating chamber, a door for opening and closing the heating chamber, and heating means for heating an object to be heated in the heating chamber.

Is a control device composed of a microcomputer,
The heating means 3 and the rotating means 7 are controlled according to the type of cooking,
The heating means 3 is stopped or the movement of the moving table 4 is controlled by the driving means 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 cooker main body accommodates the driving means 5, the moving means 6, the rotating means 7, and the open / close detecting means 8. Reference numeral 11 is a weight detecting means for detecting the weight of the object to be heated placed on the moving table 4. Reference numeral 12 is a rotational position detecting means for detecting the rotational position of the movable table 4. Reference numeral 13 is a lock detecting means for fixing the door while it is open. Reference numeral 14 is an abnormality notifying means for notifying a movement defect of the movable table 4.

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

When the heating means 1 (high frequency or electric heat energy) is used to start heating and cooking food, the control device 9 first opens / closes the door 2 by means of the opening / closing detection means 8 (for example, a micro switch or a position sensor). After confirming that there is, the drive means 5 (for example, a motor and a link cam mechanism) is drive-controlled to move the moving table 4 to the outside 1 of the constant size heating chamber. After the object to be heated to be cooked is placed on the moving table 4, the control device 9 again controls the driving means 5 to store the moving table 4 in the heating chamber 1.

Subsequently, when the door 2 is closed, the control device 9 controls the weight of the object to be heated placed on the moving table 4 by the weight detecting means 11 (for example, a strain gauge for converting strain of load change into an electric signal). , And the heating means 3 and the rotating means 7 are drive-controlled based on the weight information, and heating is performed while rotating the object to be heated so as to prevent uneven heating.

Upon completion of heating and cooking, the movable table 4 is stopped by the rotational position detection means 12 at the same rotational position (movable position) as before the cooking with the door 2 side as the moving direction. When the door 2 is opened, the open / close detection means 8 for detecting the open / closed state of the door 2 detects that the door 2 is fully open, and the control device 9 controls the drive means 5 to drive the movable table 4 on which the object to be heated is placed. Are sent to the outside of the heating chamber 1.

Further, in the movement operation of the movable table 4, if there is a gap between the heating and cooking end time and the time when the movable table 4 stops rotating at a movable position facing the door, the same time as the heating and cooking end time. At the movable position, the moving table 4
In order to stop the rotation of the movable table 4, the movable table 4 is smoothly deployed and the time difference is determined and the movable table 4 is rotated. Alternatively, after the heating and cooking is completed, the movable table 4 is stopped at the movable position, and then the cooking completion is notified. Good. The control device 9 counts the time for the moving table 4 to move in and out of the heating chamber 1, so that the abnormality notifying means 14 can be used when the moving table 4 does not come out or return in a predetermined time.
It is also possible to let you know about malfunctions or misuse.

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

The open / close detecting means 8 for detecting the open / closed state of the door 2 can arbitrarily detect the open / close angle of the door 2. Therefore, when the door 2 is opened during cooking, the heating means 3 is used.
To ensure safety or to open door 2 fully,
When the moving table 4 is moving toward the outside of the heating chamber 1 and the door 2 is slightly lifted to an angle that hinders the moving operation of the moving table 4, the control device 9 drives and controls the driving means 5 to move. Practical use such as stopping the table 4 and notifying the failure or misuse by the abnormality notifying means 14 or re-driving the moving table 4 to the outside of the heating chamber 1 when the angle does not hinder again. Can easily cope with the above possible states. Moreover, it is practical if the movable table 4 can be manually put in and taken out of the heating chamber 1 at the time of power failure or when the power of the heating cooker is turned off.

In the above description, the moving means 6 is automatically moved in and out of the heating chamber 1 in response to the opening and closing of the door 2. However, the dedicated moving means 6 is unrelated to the opening and closing of the door 2.
The moving table 4 may be manually movable into or out of the heating chamber 1 as necessary, or may be manually movable in and out. In the case of manual operation, 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 even in an unstable container. It is possible to eliminate various adverse effects due to changes in the opening and closing speed of the door, and when the object to be heated does not need to be taken out such as when confirming the finish, it can be left as it is and can be freely selected.

Further, when the heating chamber 1 is cleaned, the moving table 4 and the rotating means 7 are detachable from the heating chamber 1. Therefore, it is sufficient to remove the moving table 4 and the rotating means 7 and the moving means. Since the driving means 5 of 6 is provided outside the heating chamber 1, there is nothing left in the heating chamber 1, and the cleaning property is very good.

The moving table 4 is controlled so that it is not moved during cooking but only when the door is opened, and when the moving table 6 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 means 5 so as not to start, for example, if the weight detecting means 11 is made to detect the weight of the moving table 4 and the turntable, the presence / absence of these is discriminated and the weight information is determined. If there is not, it is determined that the moving table 4 and the turntable have been removed, and the drive of the drive means 5 is controlled to be locked. If the drive means 5 is erroneously operated during cleaning, a part of the drive means 5 is heated. It is possible to prevent a situation in which the drive portion of the drive means 5 touches the hand when it protrudes inward, which may cause a failure or cause an injury. Further, when the weight of the food is too heavy to hinder the movement of the moving table 4, it is practical to control the driving means 5 so as not to drive it. As described above, the driving means 5 is driven within the predetermined weight range, and when there is no overweight or weight information, the driving means 5 is controlled so as not to be driven, so that safe operation and smooth operation can be prevented. I can.

Further, when the movable table 4 is not in the front position facing the door 2 and the movement is hindered, or when the movable table or the turntable is removed or the weight of food is over, the movement is hindered or the door is moved. In the case where 2 is closed and there is a hindrance to movement, etc., the rotational position detection means 12, the weight detection means 11, the open / closed detection means 8, etc. are used to determine whether there is any hindrance, and control is performed so that the driving means 5 is not driven. At the same time, if necessary, the abnormality notification unit 14 notifies the abnormality information of the relevant part by distinguishing it by sound, light, characters, etc., so that it can be restored to a normal state or a failure notification, etc. The sound, light, and letters may be appropriately notified individually or in combination. In particular, when the movable table 4 is moving or protrudes out of the heating chamber 1, by controlling the lock means 13 so that the door 2 is not closed, the door 2 is inadvertently closed and the movable table 4 is closed. It is possible to prevent the food from spilling or causing a malfunction.

Regarding the heating means 3, high-frequency heating and / or electric heating may be added individually or simultaneously at the same time according to the menu for cooking, and particularly in the case of oven cooking using electric heating, the heating chamber 1 is heated hot. For this reason, there is a risk of burns by touching the wall of the heating chamber 1 when putting the hand in the heating chamber 1 after cooking and taking out the object to be heated. The functions of the present invention appearing outside are significant in that the above danger can be prevented.

[0026]

As described above, according to the present invention, since the object to be heated placed on the movable table comes out of the heating chamber as needed, the object to be heated is heated even when the heating chamber is heated hot such as in oven cooking. The heated material can be easily taken out, the risk of burns can be avoided, the heating chamber can be easily cleaned when cleaning after cooking is completed, and the potential for injury or failure during cleaning can be eliminated.
In addition, regardless of the cooking menu, when the object to be heated is heavy or the heating cooker is installed at a high position, the object to be heated can be taken in and out of the heating room, which is very convenient and practical. Highly effective.

Further, the drive means for moving the movable table, the rotating means of the movable table, the rotational position detecting means of the movable table, the weight detecting means of the object to be heated, the door open / close detecting means, these control devices, and the trouble of the movement. Since it is provided with an abnormality notifying means for informing, the movement of the heated object to the inside or outside of the heating room, the rotation operation to prevent uneven heating, the rotation stop position of the moving table, the weight of the heated object, while interlocking with the opening and closing of the door, It enables a series of automation in cooking operations such as heating and cooking and moving the heated object inside and outside the heating room.The moving table is not in front of the door, the moving table or turntable is removed, If there is an obstacle such as over-weighting or the door is closing, it will notify each abnormality and stop the movement, so it is safe and it can be corrected to normal. It can provide the coming heating cooker.
