Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to move a moving table on which an object to be heated is placed in and out of a heating chamber, and to equip the driving device outside the heating chamber to enhance the 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. 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 inside or outside of the heating chamber, a turntable rotating means is provided, the turntable is rotated by the rotating means, and a door opening / closing detecting means and a weight detecting means are provided, so that the door is heated when the door is opened. Japanese Patent Laid-Open No. 61-119921 proposes a device that can detect the weight of an object and perform heating and cooking based on the weight detected 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.

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.

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 worn so severely that the gears come into strong contact with each other when the door is suddenly closed. However, there are various problems such as breakage of the gear and deformation of the shaft.

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. Since there is no means to move the heated object to and from it, it is inconvenient to take in and out the object to be heated, and when the object to be heated is spilled into the heating chamber, the turntable and its receiving are not taken into consideration even if the door is opened. The rear part of the table remained in the heating chamber, and 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. A moving table on which an object to be heated in the heating chamber is placed and which can be freely moved in and out of the heating chamber; a moving device provided with a driving device outside the heating chamber to move the moving table into and out of the heating chamber; In a heating cooker equipped with a rotating means for rotating the table in the heating chamber, the movable table is located on the rotating means, the drive device is located outside the heating chamber, and an opening / closing detection means for detecting opening / closing of the door, and a heating means, A control device for controlling the moving means, the rotating means, the opening / closing detecting means, etc. is provided, and the moving means and the rotating means arranged inside the moving table and the heating chamber are configured to be detachably mounted from the heating chamber and placed on the moving table. The weight of the heated object Those having a weight detecting means.

[0010]

With the above construction, the exclusive moving means provided in the heating cooker having the rotating means of the moving table determines the moving speed of the object to be heated placed on the moving table depending on the door opening / closing speed. It is possible to determine arbitrarily without needing to do so, it is possible to obtain a smooth operation without falling even in an unstable container, and it is possible to eliminate various adverse effects due to changes in the door opening / closing speed.

Further, the moving table is placed on the rotating means, the driving device for moving the moving table is installed outside the heating chamber, and the opening and closing detecting means and the weight detecting means are provided. The opening and closing detecting means opens and closes the door. When the door is opened, the drive unit of the mobile stand is operated, and the drive unit is operated or stopped at any door opening / closing angle, and when the door is closed, the weight detection means detects the weight of the object to be heated placed on the mobile stand. After detecting, the moving table is rotated and heated evenly based on the weight information, and after cooking is completed, the removable moving table and rotating means can be removed from the heating chamber for cleaning, and the system and size of the device, etc. The degree of freedom of is large.

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 is a heating chamber for accommodating an object to be heated, and a door 2 which can be opened and closed is provided on the front surface of the heating chamber 1. 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. Reference numeral 4 denotes a heating chamber 1 on which the object to be heated is placed.
It is a movable table that is movably provided inside and outside of. Reference numeral 5 is a drive device that allows the moving table 4 to be moved 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 detection means for detecting the open / closed 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 control device 9, 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, and the 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.

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 of food, the control device 9 first confirms that the opening / closing detection means 8 (for example, a micro switch) of the door 2 indicates that the door 2 is in the open state. After the confirmation, the driving device 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 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.

When the cooking is completed and the door 2 is opened, the opening / closing detection means 8 for detecting the open / closed state of the door 2 detects that the door 2 is fully opened, and the control device 9 controls the drive device 5 to be heated. The movable table 4 on which the object is placed is sent out to the outside of the heating chamber 1.

The above is the description of the operation example 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.

Since the opening / closing detecting means 8 for detecting the open / closed state of the door 2 can arbitrarily detect the opening / closing angle of the door 2, if 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 reach an angle that hinders the moving operation of the moving table 4, the controller 9 drives and controls the driving device 5 to move. It is possible to easily cope with a practically possible state such as stopping the table 4 or re-driving it when the angle does not hinder again and continuing the operation of sending the moving table 4 out of the heating chamber 1.

In the above description, the moving means 6 is adapted to automatically move the moving table 4 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, the moving table 4 and the rotating means 7 can be removed, and the moving means can be removed. 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 structure for rotating the moving table 4 and moving the heating table 1 in and out of the heating chamber 1 may be, for example, as follows. The rotating means 7 may be a drive motor shaft provided outside the heating chamber 1 to which a turntable is detachably mounted,
By placing the movable table 4 on this turntable, the movable table 4 becomes rotatable. The moving means 6 is provided with a plurality of rollers on a part of the moving table 4 so that the moving table 4 can move smoothly on the turntable, and is provided outside the heating chamber 1 when the moving table 4 needs to be moved. A part of a certain driving device 5 is moved in and out of the heating chamber 1 (for example, only a push rod is driven in and out of the heating chamber 1 as a driving device in which a motor, a crank, and a push rod are combined), and a movable table is used. The movable table 4 may be moved in and out of the heating chamber 1 by pushing and pulling the table 4. The movable table 4 may be manually movable into or out of the heating chamber 1 as needed.

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.

The heating means 3 may be provided with an electrothermal heater above or below the heating chamber 1 as a configuration for electrothermal heating, but when an electrothermal heater is provided below the heating chamber 1, convection or radiation heating is performed. However, even if the movable table 4 is made of a metal material, it is deformed or discolored by the heat of the electric heater. In order to avoid this, the distance between the electric heater and the movable table 4 must be appropriately separated, and the effective vertical dimension of the heating chamber 1 tends to be small.
As a means of not reducing the vertical effective size of the heating chamber 1,
A hot air heating method using an electric heater and a fan motor may be used. Since the hot air blowing temperature is almost the same as the cooking temperature, the heater temperature is lower than that of the convection or radiation heating method. Not only can the temperature distribution be made substantially even, but the hot air outlet also has the advantage of increasing the degree of freedom in the arrangement positions such as the side surface and the rear surface of the heating chamber 1, and these can be used as necessary.

[0026]

As described above, according to the present invention, the dedicated moving means is provided, and the object to be heated placed on the moving table comes out of the heating chamber as needed, so that the heating chamber such as oven cooking becomes hot. The object to be heated can be easily taken out even when it is heated, and the risk of burns can be avoided. 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 comes out of the heating chamber, making it easy to take and very convenient. , The moving speed of the object to be heated placed on the moving table can be arbitrarily determined without being influenced by the door opening / closing speed, and smooth operation can be obtained without falling even in an unstable container, the door opening / closing speed It is effective in eliminating various adverse effects caused by changes in

Further, the movable table is located on the rotating means, the drive device for the movable table is installed outside the heating chamber, and the movable table is provided with the open / close detecting means and the weight detecting means to operate or stop the drive apparatus at any door opening / closing angle. Since the weight detection means detects the weight of the object to be heated placed on the moving table, even in the case of high frequency heating, there is no problem with sparking, abnormal heating, radio wave leakage in the drive device, and cleaning At this time, the heating chamber can be easily cleaned and the potential for injury or failure during cleaning can be eliminated, which has a high degree of practicality, and there is a large degree of freedom in terms of equipment type and equipment size. Since there are few restrictions on the distance and it can be arbitrarily determined, it is possible to improve the practicality and safety as a cooking device. Furthermore, the rotation operation to prevent uneven heating, the movement operation of the heated object to the inside and outside of the heating room, the weight detection of the heated object, the door opening / closing speed and the impact of the opening / closing, etc. 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 without a problem.
