Description

  The present invention relates to a cooking device capable of changing the moving speed of a drawer.

  Conventionally, a cooking device has been proposed in which a drawer body integrated with an opening / closing door can be pulled out to the front side of the cooking device. This type of drawer-type cooking device can be installed in the kitchen under the counter top and can be installed without occupying the counter top, and is suitable for a kitchen configuration in which a plurality of cooking appliances are arranged three-dimensionally. For this reason, the drawer-type heating cooker is positioned as one of the cooking appliances constituting the system kitchen, and in particular in the United States, the spread has been increasing in recent years.

  As an example of a drawer-type heating cooker, the bottom plate interlocking with the front open / close door can be smoothly slid with respect to the device main body by a slide mechanism, and the output of the motor provided on the device main body side can be changed to a pinion rack mechanism, etc. A structure has been proposed in which a bottom plate is opened and closed together with an opening and closing door by a transmission means (see Patent Document 1). The door opening / closing device includes a latch device for closing and holding the opening / closing door, a door opening / closing switch, and a control circuit for driving the motor so as to open / close the door in response to a signal from the door opening / closing switch. When the door open / close switch is pressed, the latch is automatically released, and the open / close door and the bottom plate are interlocked and opened / closed by the driving force of the motor.

  The applicant also cooks a drawer body having a heating chamber, a drawer body movably arranged in the cooking body so that the cooking chamber body can be pulled out from the heating chamber of the cooking body, and a drawer body. By providing a slide rail for moving the inside of the vessel body and providing the slide rail outside the heating chamber, there is no need to construct a slide mechanism with parts or materials having high heat resistance and flame retardancy, and the microwave Has proposed a drawer-type heating chamber cooker that can prevent the occurrence of defective discharge due to (see Patent Document 2).

  In addition, the present applicant sets a limit on the moving speed for moving the drawer body including the heating container with respect to the cooker body, and prevents the heated object from spilling out of the container due to an impact that acts when the movement starts or stops. The drawer-type heating cooker which can keep the inside of a heating container clean is proposed (refer patent document 3). This type of drawer-type heating cooker has a cooker body in which a microwave heating chamber is formed, a storage position in the heating chamber with respect to the cooker body, and a drawing position from the heating chamber to the outside. The drawer body is provided so as to be movable via a slide rail. Since the moving speed of the drawer body is set to 12 cm / s or less, it is possible to prevent the heated object including the liquid from spilling at the start and stop of the movement. Moreover, since the moving speed is set to 8 cm / s or more, the time required to open and close the opening / closing door is not unnecessarily long, and the user is not uncomfortable.

However, the opening / closing speed of the opening / closing door is sufficiently safe to prevent the container from being spilled even if the container is unstable or the heated object is liquid. It is inevitable to set the speed as slow as possible. In other words, although it is possible to open and close the door more quickly, it is set late so that tall containers such as coffee mugs do not fall or liquids such as soup spill from the soup plate Therefore, the automatic opening / closing mechanism is not fully capable.

  Therefore, in the drawer-type heating cooker, the automatic opening / closing speed of the open / close door when taking in and out the food, that is, the moving speed of the drawer body can be made variable, and the user can freely set it from the operation unit, At first glance, it seems to contribute to the convenience of the user, but from the user's point of view, when he / she feels dissatisfied with the moving speed of the heating cooker, It is complicated, and if the user misoperates, it will appear at a moving speed that is unintentional at the time of the next cooking, so the user is expected to have a great dissatisfaction. Therefore, it is an issue to create a change operation that does not make the user feel complicated and changes the moving speed to a moving speed that matches the user's intention.

  The object of the present invention is to solve the above-mentioned problem, and when a user tries to assist opening and closing by applying an operating force to the door, or depending on the operating force from the next time, Thus, it is an object to provide a drawer-type heating cooker that is easy to use with respect to the opening / closing speed of the opening / closing door that does not require the user to change the moving speed of the drawer body with particular attention.

  In order to solve the above-described problems and achieve the object, a drawer-type cooking device according to the present invention includes a cooking device body in which a microwave heating chamber is formed, and the cooking device body into the heating chamber. A drawer body disposed so as to be movable between a storage position of the heating chamber and a drawer position to the outside from the heating chamber, cooking menu selection means for selecting the cooking menu, and a moving speed of the drawer body, The movement speed storage means for storing each selected cooking menu and the operation mode by the cooking menu selected by the cooking menu selection means detect the force applied to the drawer when the drawer is automatically moved. In the force detection means and the movement speed storage means, the movement speed corresponding to the cooking menu is changed to a movement speed according to the content detected by the force detection means. Characterized in that further to and a moving speed controlling means for storing.

  According to this drawer-type heating cooker, when the user operates the automatic opening / closing door to automatically open and close in the automatic operation mode by the cooking menu selected by the cooking menu selection means, When an operation is performed to prevent the opening and closing, the direction and the degree of the operation are detected by the force detection means. The moving speed of the drawer is changed for each cooking menu according to the detected contents and stored in the moving speed storage means. Therefore, when the user selects the cooking menu again, the drawer body reads the changed movement speed stored in the movement speed storage means and drives the drawer body at the movement speed. it can. Therefore, the moving speed of the drawer body (that is, the opening / closing speed of the opening / closing door) can be adjusted according to the user's convenience, and the ability of the automatic opening / closing mechanism can be fully exhibited.

  In the drawer-type heating cooker, the moving speed control means corresponds to the cooking menu stored in the moving speed storage means in the next operation mode by the cooking menu selected by the cooking menu selection means. The moving speed can be read out, and the moving speed of the drawer can be set to the read out moving speed. When the same cooking menu is selected by the cooking menu selection means, the movement speed corresponding to the cooking menu stored in the movement speed storage means is read, and the movement in which the movement speed of the drawer is read Set to speed. Therefore, the moving speed of the drawer is moved at the updated moving speed, and the previous user's usability is reflected in the next operation mode. Also, even if the user is not aware that the setting of the moving speed of the drawer body is adjusted, the moving speed of the drawer body has been changed several times while using the heating cooker, and gradually becomes appropriate. The opening and closing speed will change.

  In this drawer-type heating cooker, the moving speed control means sets a change width of the moving speed to a speed change width that is one step faster or slower than a predetermined speed, and depends on an action direction of the force detected by the force detection means. The moving speed that is changed and stored can be a moving speed that is increased or decreased by the speed change width. By limiting the change speed of the moving speed to a predetermined speed change that is one step faster or one step slower, it is possible to suppress the change width of the moving speed of the drawer and avoid changing the moving speed extremely. it can.

  In this drawer-type heating cooker, it is preferable that the drawer body includes an open / close door that closes the opening of the heating chamber when the drawer body is in the storage position in the heating chamber. The user recognizes the opening / closing speed of the opening / closing door and helps to increase the opening / closing speed of the opening / closing door, or tries to prevent the opening / closing. By providing the opening / closing door on the drawer body, by applying a force to the opening / closing door, the force applied to the drawer body during automatic movement is detected.

  Since the drawer type cooking device according to the present invention is configured as described above, the following special effects can be achieved. That is, the moving speed control means as a microcomputer makes the opening / closing speed of the opening / closing door variable according to the contents stored for each cooking menu, so it is slow when food is likely to spill (liquid etc.), otherwise The user can set the optimum speed for each cooking menu, such as fast. In addition, even if the user is not aware that the settings are being adjusted, the speed will be changed to an appropriate opening / closing speed while using it, so that the ability of the automatic opening / closing mechanism can be maximized. it can.

  FIG. 6 is a block diagram relating to a moving speed control device for controlling the drive mechanism of the drawer-type heating cooker according to the present invention. Around the moving speed control device 60, a cooking menu selection means 61 for the user of the heating cooker to select a specific menu from a plurality of cooking menus prior to cooking, and the user moves the drawer body 2. Force detecting means 62 for detecting the force applied to the opening / closing door 4 in an attempt to change the speed (door opening / closing speed of the opening / closing door 4), display means 63 for displaying information on the moving speed of the drawer body 2, and the drawer body 2 for each menu And a moving speed storage means 64 composed of a non-volatile memory or the like for storing the moving speed.

  The force that the user applies to the opening / closing door 4 in an attempt to change the moving speed of the drawer body 2 appears, for example, as a force that increases or decreases the motor speed in the motor 51 of the drive mechanism 50, so that the force detection means 62. Can be detected as a change in the current value applied to the motor 51 or the like. The cooking menu selection means 61 uses a selection button provided in advance on the front surface of the heating cooker or a display means 63 such as a liquid crystal display to display a cooking menu stored in advance and select from the menu. It can be provided as a function. The moving speed storage means 64 that stores the moving speed of the drawer 2 for each cooking menu can be a non-volatile memory that stores the contents of the door opening / closing speed for each cooking menu, so that it is not erased even when the power is turned off. .

  The moving speed control device 60 includes a CPU 70 as a central processing means for performing internal calculations, a writing means 71 for rewriting the stored contents in the moving speed storage means 64 by a command from the CPU 70, and a moving speed storage by a command from the CPU 70.

And a drive mechanism control means 73 for setting the above.

  According to the moving speed control device 60, in an operation mode in which automatic cooking is performed according to the cooking menu selected by the cooking menu selection means 61, the user applies a force to the opening / closing door 4 when the opening / closing door 4 is automatically opened / closed. When trying to help or to prevent opening and closing, the force applied to the drawer body 2 at that time is detected by the force detection means 62 along with its direction. Adjusting the setting of the moving speed of the drawer body 2 (that is, the door opening / closing speed of the open / close door 4) in the next operation mode when the cooking menu is selected based on the detection information in the force detection means 62. Can do.

  Specifically, in the operation mode of the automatic cooking menu, the opening / closing door 4 at the time of door closing operation of the opening / closing door 4 before starting cooking (door closing operation of the opening / closing door 4 for putting food into the warehouse) or after cooking is finished. When the user tries to assist opening and closing by applying force to the opening and closing door 4 during the door opening operation (door opening operation of the opening and closing door 4 for taking out food), the size and direction of the force detection means 62 The CPU 70, which has detected (the door opening direction) and received the detection information of the force, instructs the writing means 71 to cause the moving speed storage means 64 to move up one step in the cooking menu and speed up the new movement. Remember speed. When the same cooking menu is selected by the cooking menu selection means 61 next time and cooking is performed using the cooking menu, the CPU 70 that has received information from the cooking menu selection means 61 that the cooking menu has been selected reads. The means 72 is instructed to read the updated moving speed one step higher from the moving speed storage means 64. The CPU 70 having received the information on the moving speed instructs the driving mechanism control means 73 to drive the drawer 2 at the moving speed one step higher, and the moving speed control device 60 sets the driving mechanism 50 according to the setting of the moving speed. Control.

  In addition, when the user tries to prevent the door from being opened and closed by opening and closing the door 4, the force detection means 62 detects its size and direction (door closing direction), The CPU 70 causes the moving speed storage means 64 to store a new moving speed that has been lowered by one step in the cooking menu. Then, when cooking is performed on the same cooking menu next time, the CPU 70 reads the updated moving speed one step slower from the moving speed storage means 64 in the same way as when trying to help open and close the door. The means 73 is commanded to drive the drawer 2 at the one-step faster moving speed, and the moving speed control device 60 controls the drive mechanism 50 by setting the moving speed.

  In this way, the latest driving content can be reproduced for the moving speed of the drawer 2 according to the selected cooking menu. In each household, the amount of containers and food used for each cooking menu is often correlated with the most recent use of the same cooking menu. Depending on the soup or solid matter, a cooking device that is easy to use with respect to the moving speed of the drawer 2 can be realized.

  Moreover, the memory heating function 65 which can memorize | store a cooking sequence by the user can be provided, and also about the memory heating, the memory area of the drawer body 2 is secured by providing the moving speed storage means 64 in the same manner. As the moving speed, a moving speed corresponding to a state change such as a change from a liquid to a solid is stored according to the cooking process, and the moving speed of the drawer body 2 can be controlled in the same manner as described above. .

  In the above embodiment, the CPU 70 automatically updates the moving speed storage means 64 to a new moving speed based on the detection information of the force detecting means 62, but displays that fact on the display means 63 before the update. An inquiry may be displayed asking whether the user is to update. Further, even after the movement speed is updated in the movement speed storage unit 64, it is possible to display the movement speed in stages and to take an option of returning to the movement speed before the update.
