Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables an object to be heated placed on a moving table to be moved in and out of a heating chamber, and a driving device thereof 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 and 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. Japanese Utility Model Application Laid-Open No. 4-57108 proposes that the movable table is not connected to the rotating means and the movable table is prevented from rotating so that the object to be heated can be easily installed and taken out.

On the other hand, although there is no means for moving the heating table inside or outside the heating chamber, a turntable rotating means is provided, and in addition to rotating the turntable by the rotating means, a rotating operation means of the rotating means is provided, and the turntable is heated after the heating is completed. The one that can be rotated to a position where it is easy to take out
According to Japanese Patent Laid-Open No. 117818, etc., there is no means for moving into and out of the heating chamber and door opening / closing detecting means, but a turntable rotating means is provided, and the turntable is rotated by the rotating means, and the stop angle of the turntable is determined. Japanese Patent Laid-Open No. 2-276190 proposes a means for providing a means for stopping the rotation of the turntable within 1/4 or at an angle of 3/4 or more with respect to the rotation start position after heating.

[0004]

However, in the above-described heating cooker, the movable table, which is movable in and out of the heating room by interlocking with the former door, interlocks with the door, so that the door can be opened and closed. The speed affects the speed at which the turntable appears and disappears inside and outside the heating room, and the appearance speed is not constant. There is a risk of burns when the object to be heated is hot because the object to be heated falls down or spills if the object to be heated is a liquid.

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.

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, it is necessary to lengthen the connecting member. 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.

Since the rotating gear of the turntable and the gear of the driving device are attached and detached each time the door is opened and closed, the gears are severely worn, and when the door is suddenly closed, the gears hit each other strongly. However, there are various problems such as breakage of the gear and deformation of the shaft.

Further, in the latter one provided with the rotating operation means of the rotating means and the stop angle judging means, the object to be heated cannot be moved in and out of the heating chamber, so that the object to be heated or after heating is not installed. It is not easy to take out the heated object, and when the heated object is spilled into the heating chamber, the turntable and its pedestal remain behind the heating chamber because the turntable is not attached or removed. It was extremely difficult to clean not only the turntable and its cradle but also the backside and the bottom of the heating chamber.

[0009]

It is possible to obtain smooth operation without falling even in an unstable container, and eliminate various adverse effects due to changes in the door opening / closing speed.
It also has good cleanability.

Further, the opening / closing detecting means detects the opening / closing of the door, operates the drive device of the moving table when the door is opened, operates or stops the driving device at an arbitrary door opening / closing angle, and rotates the moving table during cooking and heating. After the cooking is completed, the rotation position detecting means detects the rotation position of the moving table and stops the moving table at a movable position facing the door, thereby improving the practicality and safety of the heating cooker. Is.

In addition, the rotation position detecting means uses the heating and cooking time as a reference in order to match the timing of stopping the rotation of the moving table by the rotating means with the heating and cooking end time and the time of stopping at the movable position relative to the door. In order to determine the deviation of the rotation start time of the moving table and rotate it, or to match the heating cooking end time and the time to stop at the movable position relative to the door, the moving table moves relative to the door after heating. After stopping at the possible position, it is advisable to notify the end of cooking.

In addition, the rotation position detecting means shifts the rotation stop timing of the moving table by the rotating means from the time when the moving table is stopped at the movable position facing the door at the time when the cooking is finished to within about 1/2 rotation. Is stopped before heating,
The heating may be stopped after the heating is completed for about 1/2 rotation or more.

Further, it is preferable that the control device counts the time during which the moving table moves into and out of the heating chamber and informs the user when the moving table does not go in and out within a predetermined time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the heating cooker according to the present invention.

In the figure, reference numeral 1 denotes a heating chamber for accommodating an object to be heated, and a front door of the heating chamber 1 is provided with an openable / closable door 2. Reference numeral 3 denotes a heating means (for example, a high-frequency generator or an electric heater) that generates energy for heating an object to be heated in the heating chamber 1.
It is a movable table that is movably provided inside and outside of. Reference numeral 5 is a drive device that enables the moving table 4 to move in and out of the heating chamber 1, and 6 is a moving means including the drive device 5.
Reference numeral 7 denotes a rotating means for rotating the moving table 4 in the heating chamber 1, which is located below the moving table 4. Both the moving table 4 and the rotating means 7 are detachably attached to the heating chamber 1. 8
Is an opening / closing detecting means for detecting the opening / closing state of the door 2, and can arbitrarily detect the opening / closing angle of the door 2. Reference numeral 9 denotes a control device composed of a microcomputer, which controls the heating means 3 and the rotating means 7 according to the type of cooking, and stops the heating means 3 according to the opening / closing angle of the door 2 or moves it by the drive device 5. The movement of the table 4 is controlled. Reference numeral 10 denotes a cooker main body which houses the heating chamber 1, the door 2, the heating means 3, the moving table 4, the driving device 5, the moving means 6, the rotating means 7, the detecting means 8 and the control device 9. 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.

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

When the heating means 3 (for example, high frequency or electric heat energy) is used to start heating and cooking of food, the control device 9 first confirms that the door 2 is in the open state by the open / close detection means 8 (for example, a micro switch). After that, the drive unit 5 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 device 5 to store the moving table 4 in the heating chamber 1.

Subsequently, when the door 2 is closed, the control device 9 detects the weight of the object to be heated placed on the moving table 4 by the weight detecting means 11, and based on the weight information, the heating means 3 and Heating is performed while rotating the object to be heated so as to prevent uneven heating by controlling the rotating means 7.

When the heating and cooking is completed, the movable table 4 is stopped by the rotational position detecting means 12 at the same rotational 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 is fully opened, and the control device 9 drives and controls the drive device 5 to heat the movable table 4 on which the object to be heated is placed. Send it to the outside of chamber 1.

In addition, in the moving operation of the movable table 4, when there is a gap between the cooking end time and the time when the movable table 4 stops rotating at the movable position relative to the door 2, the same time as the cooking end time. The rotation start time of the movable table 4 is determined so that the movable table 4 is stopped at the movable position relative to the door 2, and the movable table is rotated after the cooking is finished, or the movable table is stopped at the movable position relative to the door 2. It suffices to notify the end of post-cooking.

The timing for stopping the rotation of the moving table 4 is before the end of heating when the difference between the time when the cooking is finished and the time when the moving table 4 is stopped at the movable position relative to the door 2 is within about 1/2 rotation. It is possible to reduce the deviation of the notification time by stopping after 1 hour and stopping after heating for about 1/2 rotation or more. In addition, the control device 9 can also notify the failure or misuse when the moving table 4 does not come out and return within a predetermined time by counting the time when the moving table 4 moves into and out of the heating chamber 1. is there.

The above is an example of the operation when the object to be heated is placed on the movable table 4 while the movable 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.

Since the opening / closing detecting means 8 for detecting the opening / closing state of the door 2 can arbitrarily detect the opening / closing angle of the door 2, when the door 2 is opened during cooking, the heating means 3 is used.
To ensure safety or to open door 2 fully,
While the movable table 4 is moving to the outside of the heating chamber 1, if the door 2 is lifted up a little to an angle that hinders the movement operation of the movable table 4, the controller 9 drives and controls the drive device 5 to move the movable table 4. It is possible to easily cope with a practically possible state such as stopping 4 or re-driving when the angle does not hinder again and continuing the operation of sending the movable table 4 out of the heating chamber 1. 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 corresponds to the opening / closing of the door 2 and the moving table 4 is automatically moved in and out of the heating chamber 1. However, the dedicated moving means 6 irrelevant to the opening / closing of the door 2 is used.
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, since the moving table 4 and the rotating means 7 are detachable from the heating chamber 1, it is sufficient to remove the moving table 4 and the rotating means 7 and the moving means. Since the driving device 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. A configuration in which the drive of the drive device 5 is controlled so as not to start (for example, if the weight detection means 11 is made 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 displayed. If it does not exist, it is determined that the moving table 4 or the turntable has been removed, and the drive of the driving device 5 is controlled to be locked).
It is possible to prevent a situation in which the drive portion of the drive device 5 touches the hand when it protrudes inward, which may cause a failure or cause an injury.

Regarding the heating means 3, high frequency heating and / or electric heating may be added individually or at the same time depending on 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.

[0031]

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 during cleaning, and the practical effects such as handling are high. Further, 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 comes out of the heating chamber, which is easy to take and is very convenient.

Further, the rotation operation for preventing uneven heating, the movement operation of the object to be heated to the inside or outside of the heating room, and the interlocking with the opening / closing of the door are not affected by the door opening / closing speed or the opening / closing shock. It is possible to provide a heating cooker capable of automating a series of cooking operations such as heating and moving an object to be heated into and out of a heating room.

Further, an opening / closing detecting means for detecting the opening / closing of the door and a rotational position detecting means for detecting the rotational position of the moving table are provided, and the driving of the moving table is operated or stopped at an arbitrary door opening / closing angle to finish cooking. After that, since the movable table is stopped at a movable position opposite to the door, an object to be heated is easily taken out when the movable table is stopped, cleaning efficiency of the heating chamber is very good, and a highly practical heating cooker is provided.
