Description

  The present invention relates to a cooking device that detects a user's motion and performs various controls in a non-contact manner, and is not intended by the user by limiting the conditions for detecting the user's motion, particularly in a non-contact operation. The present invention relates to a heating cooker that prevents cooking failure due to operation.

  Conventionally, when operating a cooking device during preparation for cooking, it has been necessary to wash dirty hands or to know that the operation section is dirty. If you operate the control unit with your hands dirty, you may have slipped and pressed the buttons incorrectly, or you could not turn the dial as you thought, and it was difficult to operate as intended by the user.

  Further, it is necessary to take care of the dirty operation section after the operation, and there are problems such as leaving the dirt unattended, and if it is poorly maintained, it may be hygienic and cause a failure.

  In addition, in recent years, a cooking device with a touch panel on the operation unit has been released, but operations with dirty hands are particularly noticeable for poor visibility and misrecognition. In order to prevent erroneous operation, it was necessary to take further steps such as unplugging the main body and turning off the power.

  On the other hand, there is one that can be operated by voice recognition as one that can be operated without contact (for example, Patent Document 1).

Japanese Patent No. 3951705

  However, the conventional configuration has a problem that it cannot be operated unless the voice is accurately recognized. In addition to noise related to other cooking appliances such as a range hood in the kitchen, in recent years, an increasing number of users cook while listening to music and TV, and there are many factors that lower the speech recognition rate. If the voice is not recognized, the user must generate words many times, and when trying to eliminate noise in order to increase the voice recognition rate, the operation part of each device will be dirty. It becomes necessary to operate, and the problem that the operation section becomes dirty spreads to other devices. In addition, there is a possibility of erroneous operation due to misrecognition, and in particular, when an operation unintended by the user regarding heating control is performed, cooking failure due to overheating or insufficient heating will be caused, resulting in poor usability. There is a problem of end.

  As another non-contact operation method, it is conceivable to control the operation by detecting the movement of a human body such as a hand or a finger, but this is the same because it is not a direct operation.

  The present invention solves the above-described conventional problems, and improves cooking by non-contact operation, and prevents cooking failure due to operation unintended by the user by limiting conditions for detecting the user's movement. An object of the present invention is to provide a heating cooker.

In order to solve the above-described conventional problems, the heating cooker of the present invention directly selects a heating means for heating an object to be heated, a cooking menu and heating conditions, and controls start and stop of the heating means. Input means; storage means for storing at least cooking method and display data; display means for displaying information stored in the storage means and a heating control state; control for controlling the heating means and the display means And a motion detection means for detecting a motion of a part of the human body in a non-contact manner, the control means accepts an input from the motion detection means only when the heating means is not operating, and the motion controlled based on the input result from the detection means, the control means, which the start control of the heating means is adapted to control only based on input from the direct input means A.

  As a result, the non-contact operation can be used in a state other than during cooking that does not affect cooking failure, and the operability can be improved, and even during the cooking, the motion detection means detects a part of the human body motion. Since it is not accepted as an operation, it is possible to prevent the cooking condition from being changed due to an operation not intended by the user and causing a cooking failure.

  According to the cooking device, the cooking method, and the program of the present invention, the user can operate the cooking device even when the hand is still dirty, and the usability can be improved.

The first invention is a heating means for heating an object to be heated, and a direct input means for selecting, determining and determining the cooking menu and heating conditions (heating mode, time, temperature, etc.) and starting and stopping the heating means. A storage means storing at least a cooking method and display data; a display means for displaying information stored in the storage means and a heating control state; a control means for controlling the heating means and the display means; A motion detecting means for detecting the operation of the part in a non-contact manner, and the control means accepts an input from the motion detecting means only when the heating means is not operating, and controls based on an input result from the motion detecting means. It is comprised so that it may do.

  As a result, it is possible to operate without contact even if the hands are dirty or wet except during cooking, and the operability can be improved.On the other hand, during cooking, the motion detection means operates part of the human body. Even if detected, it is not accepted as an operation input, so that it is possible to prevent a cooking failure such as overheating or insufficient heating due to a change in heating conditions during cooking due to an operation not intended by the user. For example, page turning when the recipe is displayed on the display means during preparation can be performed without polluting the operation unit, and the user just crosses the front of the operation unit after cooking is started There is no need to worry about cooking failure because it does not react to children or pranks of children.

  In particular, according to the second invention, in the first invention, the control means is configured to control the start control of the heating means only based on the input from the direct input means.

  As a result, cooking by the input from the motion detection means does not start, so if the user just stands in front of the operation unit or reacts to a child's mischief, heating cooking starts at a timing unintended by the user It is safe without cooking failure.

  According to a third aspect of the present invention, in particular, in the first or second aspect of the present invention, the control means does not detect an input from the direct input means or the motion detection means for a certain period of time, and the immediately preceding input is an input from the motion detection means. The input from the immediately preceding motion detecting means is invalidated.

  As a result, if the operation detected by the motion detection means is an operation not intended by the user, the operation is automatically canceled, so that the user does not need to correct the operation and prevents erroneous operation / setting. Can do.

  According to a fourth aspect of the invention, in particular, in any one of the first to third aspects of the invention, the control means is configured not to accept the input from the motion detection means for a predetermined time after accepting the input from the direct input means. It is.

  As a result, the non-contact operation becomes invalid in a state where the user can directly operate with the input means, and thus it is possible to prevent an erroneous operation / incorrect setting unintended by the user.

  In particular, the fifth aspect of the present invention, in any one of the first to third aspects, further includes an operation detection start instructing unit, and the control unit receives the start instruction from the operation detection start instructing unit. It is comprised so that the input of may be accepted.

  Accordingly, since the user can prohibit the detection of the non-contact operation when the non-contact operation is unnecessary, it is possible to further prevent the erroneous operation / setting that is not intended by the user.

  In a sixth aspect of the invention, in particular, in the fifth aspect of the invention, the motion detection start instructing means is a second motion detection means different from the motion detection means.

  Thereby, when a non-contact operation becomes necessary during the preparation, it is possible to instruct the start of the non-contact operation detection even if the hand is dirty.

  In a seventh aspect of the invention, in particular, in any one of the first to third aspects of the invention, when the control means detects a predetermined action in the input from the action detection means, the control means determines that it has received an action detection start instruction, and the action detection means It controls so that it may control based on the input result from.

  In an eighth aspect of the invention, in particular, in any one of the first to third aspects of the invention, the notification unit further includes a notification unit, and the control unit notifies the user that the input from the motion detection unit is being received. It is comprised so that it may do.

  Accordingly, the user can determine whether or not a non-contact operation is currently possible, and can be careful of an operation that causes an erroneous operation, or can be prevented from operating wastefully without detecting a non-contact operation.

  The ninth invention is a program that causes a computer to execute at least a part of any one of the first to eighth inventions, and easily implements all or part of the present invention using a general-purpose computer or a server. can do.

  Embodiments of the present invention will be described below with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a schematic configuration diagram of a microwave oven that is a typical cooking device according to Embodiment 1 of the present invention. FIG. 2 is a control block diagram of the cooking device according to Embodiment 1 of the present invention.

  In FIG. 1 and FIG. 2, the heating cooker 100 selects and determines the heating means 201 for heating the object to be heated, the cooking menu and the heating conditions (heating mode, time, temperature, etc.) and the start of the heating means. Direct input means (up / down / left / right button 101 to cancel button 104) for controlling the stop, storage means 203 storing at least a cooking method and display data, information stored in the storage means 203 and a heating control state are displayed. Display means 105 to perform, heating means 201 and control means 202 to control the display means 105, operation detection means 106 to detect a part of the human body in a non-contact manner, and the cooking device 100 is in an operation detection state. It is comprised from the alerting means 107 which notifies.

  The heating unit 201 is a device that heats an unheated object, and includes a magnetron, a heater, a circulation fan, and the like.

  Direct input means (up / down / left / right button 101 to cancel button 104) can be used for cooking, selection of cooking menu and heating conditions (heating mode, time, temperature, etc.), determination / cancellation of operation, and control of starting and stopping of heating means. This is an interface device for operating the device 100, and is composed of buttons, dials, levers, and the like.

  Further, the direct input means may be configured as a single input means for each operation target function, or the display means 105 displays selectable menu items, setting values, etc., and can be used to select items, change setting values, You may comprise as a common input means which performs functions, such as determination and cancellation.

  In the present embodiment, as the latter configuration, up / down / left / right buttons 101 for changing various set values displayed on the display means 105, selecting a menu item, and the like, and determining and heating the set values and items are selected. A start button 102 for instructing the start of control, a return button 103 for returning to the previous operation screen, and a cancel button 104 for instructing to cancel the operation (return to the initial screen) and stop the heating control. To do.

Note that buttons related to other functions such as a voice guidance start button may be provided. Further, the direct input means may be constituted by a touch panel and also used as the display means 105.

  The display unit 105 is a device that displays information stored in the storage unit 203 and the heating control state, and is a dot matrix liquid crystal. FIGS. 5, 6A to 6D, and 6E are examples of a menu screen, a setting screen, and a heating control state screen displayed on the display unit 105, respectively.

  In addition to the display of information necessary for operation of the heating cooker 100 and the control state, in the present embodiment, the heating cooker 100 has an automatic cooking menu function for cooking by automatically controlling the heating means 201. It is assumed that the recipe of the automatic cooking menu can be displayed on the display means 105 (FIG. 7).

  In this embodiment, the above-described screen information is described as an example of information displayed on the display unit 105. However, the information that can be displayed on the display unit 105 is information stored in the storage unit 203. It is not limited to the range. For example, information on usage such as an instruction manual can be displayed.

  Moreover, the heating cooker 100 is provided with a communication function, and information acquired from other devices via communication may be displayed. Further, the display method is not limited to the design exemplified in this embodiment.

  The control unit 202 provides the control function of the heating cooker 100 in addition to the control of the heating unit 201 and the display unit 105. The control unit 202 is formed by a microcomputer or the like, and is a RAM (Random Access Memory) or a ROM (Read Only Memory). Necessary setting information is stored in the storage means 203 such as a memory, and the cooking device 100 is made to function.

  The motion detection means 106 is a device that detects the motion of a part of the human body in a non-contact manner, and is composed of, for example, a thermopile type infrared sensor. A thermopile infrared sensor generates an output voltage that correlates with the temperature difference between the temperature of the sensor's field of view and the temperature of the sensor itself, and the temperature of the sensor's field of view is higher than the temperature of the sensor itself. Generates a positive voltage and generates a negative voltage at low temperatures.

  Considering that the temperature of the sensor itself is equal to the temperature of the space where the cooking device 100 such as a kitchen is installed, if the field of view is a kitchen wall, the temperature of the field of view and the temperature of the sensor itself are approximately equal to the room temperature of the kitchen. No voltage is generated. On the other hand, when a hand enters the field of view of the sensor, a surface voltage of a human body such as a palm is generally about 35 ° C., which is higher than room temperature, and thus a positive voltage is generated. It can be detected from this output voltage that a part of the human body has entered the field of view of the sensor.

  In the present embodiment, the motion detection means 106 is composed of three thermopile infrared sensors (106A, 106B, 106C), and detects the proximity (hand-holding) of a human hand and up / down / left / right motion.

  As shown in FIG. 1, the three infrared sensors are arranged in the order of A, B, and C from the left, and in the order of A, C, and B from the top. With this configuration, when a part of the human body such as a hand moves from left to right in front of the sensor, it moves in the order of A, B, and C, and when it moves from right to left, it becomes a positive output in the order of C, B, and A. The voltage can be detected.

Similarly, a positive output voltage is detected in the order of A, C, and B when moving from the top to the bottom, and a positive output voltage is detected in the order of B, C, and A when moving from the bottom to the top. Thus, the three infrared sensors 106
Depending on the order in which A, 106B, and 106C detect that a part of the human body has entered the field of view, whether the hand movement is left to right, right to left, top to bottom, or bottom to top It is possible to detect which operation is non-contact.

  In addition, with regard to the hand-holding (close proximity state of the hand), a state in which all of the three infrared sensors 106A, 106B, and 106C detect that a part of the human body is in the field of view is a predetermined time (for example, 2 It can be determined by being continuous for a second.

  Note that the present invention is not limited to this as long as it can detect a part of the human body, and a pyroelectric infrared sensor is also possible. Instead of the infrared sensor, a combination of a light emitting element and a light receiving element makes the emitted light close to each other. The operation may be detected from the order of incidence by reflecting the light from a part of the human body and entering the light receiving element. Moreover, you may detect by the imaging of a camera.

  The notification means 107 is a device that notifies the user that the heating cooker 100 is in the motion detection state, and is configured by an LED, for example.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below using the control flowchart of FIG. 3, FIG.

  When receiving the input signal from the direct input means (up / down / left / right button 101 to cancel button 104) (YES in S301), the control means 202 performs input control processing according to each input means (S302). On the other hand, when a detection signal is received from the motion detection means 106 (NO in S301 and YES in S303), the operating state of the heating means 201 is determined (S304). When the heating unit 201 is performing the heating control, the signal from the operation detecting unit 106 is discarded (YES in S304). When the heating unit 201 is not performing the heating control, the detection signal from the motion detection unit 106 is received, and the user's gesture motion is determined (NO in S304, S305).

  In the gesture motion determination process (S305, FIG. 4), if it is determined that the user has moved his / her hand from left to right based on the detection signal from the motion detection means 106 (YES in S401), the up / down / left / right button 101 of the direct input means. It is determined that the input is the same as when the right button is pressed (S402), and the same input control processing is performed (YES in S306, S302).

  Similarly, if it is determined that the user has moved from right to left, the left button (YES in S403, S404), and if it is determined that the user has moved from top to bottom, the down button (YES in S405, S406) is determined to have moved from the bottom to the top. In such a case, the same control as when the up button (YES in S407, S408) is pressed is performed. If it is determined that the operation is a hand-holding operation (YES in S409), it is confirmed whether all heating conditions (heating mode, time, temperature, etc.) are set (S410).

  If there is an unset heating condition (NO in S410), it is determined that the input is the same as when the start button 102 of the direct input means is pressed (S411), and the same input control processing is performed (YES in S306, S302). ).

  If all the heating conditions are set (YES in S410), the signal from the operation detecting means 106 is discarded. If neither operation can be determined (NO in S409, NO in S306), the detection signal from the operation detecting means 106 is discarded.

  Note that the notification means 107 is turned off during heating control that is not in the operation detection state, and is turned on otherwise.

  FIG. 5 shows an example of a menu screen displayed on the display means 105. When the direct input means (up / down / left / right button 101, start button 102) is operated on the menu screen of FIG. 5, the menu frame is selected by moving the cursor frame allocated to the menu item up / down / left / right by pressing the up / down / left / right button 101. Then, the currently selected menu can be determined by pressing the start button 102, and the display can be changed to the next screen.

  5A is an initial screen, FIG. 5B is a screen in which the right button of the up / down / left / right button 101 is pressed from the state of FIG. 5A and the cursor frame is moved to the right, and FIG. FIG. 5A shows a screen in which the down button of the up / down / left / right button 101 is pressed to move the cursor frame downward, and FIG. 5D shows the menu by pressing the start button 102 from the state of FIG. 5B. Is set to the range and the range setting screen is displayed.

  Since the heating control is not yet performed in the state where the menu screens of FIGS. 5A to 5C are displayed, the control unit 202 receives the detection signal from the operation detection unit 106 and the user's operation is performed. And the same input control processing as when the input means is directly pressed according to the operation is performed.

  For example, if the hand is moved from left to right within the detection range of the motion detection means 106 with the screen of FIG. 5A being displayed, it is the same as when the right button of the up / down / left / right button 101 is pressed. The cursor frame can be moved to the right (FIG. 5B).

  FIG. 6 shows an example of a setting screen displayed on the display means 105, which is a setting screen related to the range of the manual menu. In the operation of the direct input means (up / down / left / right button 101, start button 102) on the setting screen of FIG. 6, the cursor frame devoted to the output of the setting item or the time is moved by pressing the left / right button of the up / down / left / right button 101. The target to be set can be selected.

  In addition, by pressing the up / down button of the up / down / left / right button 101, the set value of the setting content (output or time) to which the cursor frame is placed can be set to the upper limit. The set value can be determined by pressing the start button 102 and the display can be changed to the next screen.

  6 (a) (same as FIG. 5 (d)) is the initial screen of the range setting screen, and FIG. 6 (b) is the state shown in FIG. 6 (a). 6 (c) is a screen in which the cursor frame is moved to the right by pressing the right button of the up / down / left / right button 101 from the state of FIG. 6 (b), and FIG. 6 (d) is FIG. 6 (c). FIG. 6E shows a screen in which the time set value is increased by pressing the upper button of the up / down / left / right button 101 from the state shown in FIG. 6E. The set value is determined by pressing the start button 102 from the state shown in FIG. The screen during control is displayed.

  In the state where the setting screens of FIGS. 6A and 6D are displayed, the heating control is not yet performed, and therefore the control unit 202 determines the user's operation when receiving the detection signal from the operation detection unit 106. Then, the same input control processing as when the input means is directly pressed according to the operation is performed.

  For example, in the state where the screen of FIG. 6A is displayed, if the hand is moved from top to bottom within the detection range of the motion detection means 106, it is the same as when the down button of the up / down / left / right button 101 is pressed. The output set value can be reduced (FIG. 6B). However, since all heating conditions are set in the state where FIG. 6D is displayed, the detection signal is discarded when the operation determined by the detection signal from the operation detection means 106 is a holding operation. Input control processing is not performed.

  In addition, since the heating control is performed in the state where the heating control screen of FIG. 6E is displayed, even if a detection signal is received from the operation detecting means 106, the signal is discarded and the input control process is not performed.

  FIG. 7 is an example of a screen displaying a recipe of the automatic cooking menu displayed on the display means 105, which is a screen displaying a hamburger recipe. By operating the direct input means (up / down / left / right button 101, start button 102) on the recipe screen of FIG. 7, the screen display can be sent up and down by pressing the up / down button of the up / down / left / right button 101 (page feed).

  7A is an initial screen (material) of a hamburger recipe screen, and FIG. 7B is a screen of a hamburger recipe screen by pressing the down button of the up / down / left / right button 101 from the state of FIG. 7A. Is displayed.

  In the state where the recipe screens of FIGS. 7A and 7B are displayed, the heating control is not yet performed, so that the control means 202 determines the user's action when receiving the detection signal from the action detection means 106. Then, the same input control processing as when the input means is directly pressed according to the operation is performed.

  For example, if the hand is moved from top to bottom within the detection range of the motion detection means 106 with the screen of FIG. 7A being displayed, it is the same as when the down button of the up / down / left / right button 101 is pressed. The page display of the recipe display screen can be performed. FIG. 7B shows a state in which this operation is repeated twice (a state in which page feed is performed twice).

  FIG. 8A is an example of a screen during heating control of the automatic cooking menu displayed on the display means 105, and is a screen during heating control of Chinese buns. Unlike FIG. 6E, on the screen during the heating control in FIG. 8A, the user can adjust the finish during the heating control. In contrast to FIG. 8A, in the operation of the direct input means (up / down / left / right button 101, start button 102), the strength of the finish can be changed by pressing the left / right button of the up / down / left / right button 101.

  However, since the heating control is performed in the state where the screen during the heating control in FIG. 8A is displayed, the signal is discarded even if the detection signal from the operation detecting means 106 is received, and the input control process is performed. Absent.

  FIG. 8B is an example of a screen after the cooking of the manual menu range is completed. In the operation of direct input means (up / down / left / right button 101, start button 102) with respect to the cooking end screen of FIG. 8 (b), the range setting screen of FIG. The display can be changed to the initial screen, and the heating time can be added thereafter.

  In the state where the cooking end screen of FIG. 8B is displayed, the heating control is finished, so when receiving the detection signal from the action detecting means 106, the control means 202 determines the action of the user and takes action. In response, the same input control processing as when the input means is directly pressed is performed.

  For example, in the state where the screen of FIG. 8B is displayed, if the hand is moved from the bottom to the top within the detection range of the motion detection means 106, it is the same as when the upper button of the up / down / left / right button 101 is pressed. The display can be changed to the initial screen of the range setting screen in FIG.

Note that control that cannot be operated by the direct input means (up / down / left / right button 101, start button 102) cannot be operated by the motion detection means 106. For example, in the state where the screen during the heating control in FIG. 6E is displayed, the operation of the direct input means (up / down / left / right button 101, start button 102) is not accepted. In addition, in the heating cooking end screen of FIG. Similarly,
Even when the detection signal from the motion detection means 106 is received, the signal is discarded and the input control processing is not performed.

  As described above, even when the heating unit 201 is not performing the heating control, if the operation detected and determined by the motion detection unit 106 is equivalent to the input of the direct input unit that does not accept the input control, the input control is performed. Since it is not performed, no operation beyond what the user can directly operate is safe.

  In this way, in a state other than cooking that does not affect cooking failure, even if the hand is dirty or wet, it can be operated in a non-contact manner and the operability can be improved. Even if a part of the human body motion is detected, it is not accepted as an operation, so that it is possible to prevent the cooking condition from being changed due to an operation unintended by the user and causing a cooking failure.

  Since the operation can be performed without directly touching the operation unit, it is not necessary to care for the operation unit that is dirty after the operation, and the contamination does not cause a failure. It is also hygienic because it can be operated in a non-contact manner regardless of whether or not the hand is dirty.

  For example, when a recipe is displayed on the display means for preparation for cooking, unlike a cookbook, all the ingredients and procedures cannot be displayed on one screen, so it is necessary to operate the display means to page through the work. By performing the non-contact operation described in this embodiment, it is possible to turn the page without touching the operation unit, and the usability is improved.

  There is no need to take care of the dirt on the operation unit, and the problem that it is not hygienic can be solved by touching the food again with the hand touching the operation unit.

  In addition, in a cooking device with a touch panel as the operation unit, if the entire hand is dirty, the touch panel keys cannot be pressed even with the back of the finger, so the operation cannot be performed without washing the hand. By performing the non-contact operation described in (1), it can be operated as intended by the user regardless of the amount of dirt on the hand.

  In addition, care is essential because even a small amount of dirt can lead to poor visibility and misrecognition, and since it is operated simply by touching it lightly, unplug the main unit and turn the power off before cleaning the control unit. However, by performing the non-contact operation described in the present embodiment, the operation unit is not contaminated and the maintenance work is unnecessary.

  Also, during cooking, changes in the heating conditions from the direct input means are accepted, but even if the motion detection means detects a part of the user's human body, it is not accepted as an operation input. There is no need to worry about cooking failures, and you can go back and forth in front of the range and work in front of the range. Moreover, there is no need to worry about the effects of mischief of children.

  In addition, in the state where all the heating conditions necessary for starting the heating control are set, the hand-holding operation is not accepted, that is, the heating cooking is not started by the input from the operation detecting means, so that the user is in front of the operation unit. Responding to standing up or mischief of a child, cooking is started at a timing unintended by the user, and the cooking does not fail.

  In addition, when the cooking device is in the motion detection state, the notification means is turned on to notify the user so that the user can determine whether the non-contact operation is currently possible and be careful of the operation that would cause an erroneous operation. Or non-contact operation can be prevented without being detected.

  In the present embodiment, the menu screen, the range setting screen, and the hamburger recipe screen have been described as examples of the screen in which the heating control is not performed. However, it can be controlled similarly.

  Further, in the present embodiment, the motion detection unit 106 has been described as detecting the proximity of a human hand and up / down / left / right motion, but other motions may be detected. For example, when the rotation motion of the hand is detected and it is determined that the hand is rotated to the right, the return button 103 is pressed, and when it is determined that the hand is rotated to the left, the cancel button 104 is pressed. It may be determined that the input is the same as the case.

  As described above, when the number of operations that can be detected increases, the number of functions that can be controlled is increased, and the operability can be improved. Even if the cancel button function can be operated in a non-contact manner, it can be used during cooking, because it accepts heating cancellation input directly from the input means, but does not accept operation input by detection from the motion detection means. It is safe without heating cooking stopping at a timing unintended by the person and cooking failure.

  Note that the configuration of the motion detection means 106 for detecting the rotational motion is not limited to the configuration shown in the present embodiment, and it may be configured by three or more sensors or may be configured by other sensors. Good.

  Further, the operation control content to be assigned to the operation to be detected and the detection result is not limited to the scope of the present embodiment.

  The schematic block diagram of the heating cooker 100 at the time of comprising a direct input means with a dial at Fig.9 (a) is shown.

  The cooking device 100 shown in FIG. 9A includes a dial button 901 that has the same function as the direct input means (up / down / left / right button 101 and start button 102) of the cooking device 100 shown in FIG. The dial button 901 can realize the same function as the up / down / left / right button 101 by rotating to the left / right.

  By rotating to the right, the menu selection (move the cursor in the advancing direction) and the set value can be increased, and by rotating to the left, the menu selection (move the cursor in the reverse direction) and the set value can be decreased.

  Also, by pressing the button, it is possible to instruct the same function as the start button 102, determination of setting values and item selection, and start of heating control. The motion detection means 106 may detect the proximity and left / right motion of a person's hand, and may be assigned to pressing the dial button 901, rotating to the right, or rotating to the left, respectively, The dial button 901 may be pressed, rotated clockwise, or rotated counterclockwise.

  Moreover, the schematic of the heating cooker 100 which comprised the direct input means with the touch panel in FIG. 10 is shown.

  In the cooking device 100 shown in FIG. 10, some direct input means and display means are integrated, and can be operated by directly pressing a key displayed on the display means 105. When the motion detection means 106 detects the proximity of the person's hand and up / down / left / right movement, and the movement of the hand up / down / left / right is detected, the selection of the selected menu (movement of the cursor) and the increase / decrease of the set value are increased. And select items and set values by hand-holding. The start button 102 is used to start the heating control.

  In the case of the motion detection state, the information displayed on the display unit 105 may be changed to information that can be easily operated without contact. For example, the movement of the hand for non-contact operation is displayed as an animation, an arrow is displayed in a direction in which the cursor can move, or the information to be displayed is narrowed down and displayed.

  Thereby, the user can operate more intuitively even if it is non-contact operation.

(Embodiment 2)
Next, a second embodiment of the present invention will be described.

  The difference between the present embodiment and the first embodiment is that the control unit 202 receives the input from the motion detection unit 106 and then receives the input from the direct input unit (up / down / left / right button 101 to cancel button 104) or the motion detection unit 106. Input is not detected for a certain period of time, and the previous input is input from the motion detection means 106, it is determined that the input from the previous motion detection means 106 is not an operation intended by the user, and the previous motion detection is performed. The point is that the input from the means 106 is invalidated.

  The schematic configuration diagram and the control block diagram of the heating cooker in the second embodiment are the same as those in the first embodiment.

  The operation and action will be described below using the control flowcharts of FIGS.

  Upon receiving an input signal from the direct input means (up / down / left / right button 101 to cancel button 104) (YES in S301), the control means 202 registers the direct input means as an operation input means in the storage means 203 (S1201). An input control process corresponding to each input means is performed (S302).

  There are two types of operation input means stored in the storage means 203: “direct input means” and “motion detection means”, which change under the conditions shown in FIG. When the control unit 202 receives an input from the direct input unit (up / down / left / right button 101 to cancel button 104), the control unit 202 measures an elapsed time from the input reception.

  If the elapsed time has already been registered, it is reset and measurement starts again from zero. When a detection signal is received from the motion detection means 106 (NO in S301 and YES in S303), the operating state of the heating means 201 is determined (S304). When the heating unit 201 is performing the heating control, the signal from the operation detecting unit 106 is discarded (YES in S304).

  At this time, the elapsed time during the counting is not reset and remains as it is. When the heating unit 201 is not performing the heating control, the detection signal from the motion detection unit 106 is received, and the user's gesture motion is determined (NO in S304, S305).

  In the gesture motion determination process (S305), the determination of each gesture motion is the same as S401 to 411 in FIG. After detecting the input of each button, the motion detection means 106 is registered as an operation input means in the storage means 203 (S1101), and input control processing is performed in S302.

  When the control unit 202 receives an input from the motion detection unit 106, the control unit 202 measures an elapsed time from the input reception. If the elapsed time has already been registered, it is reset and measurement starts again from zero.

  Here, when an input signal from the direct input means (up / down / left / right button 101 to cancel button 104) or a detection signal from the operation detection means 106 is not detected, the elapsed time during counting has passed a certain time. (YES in S1002), the input unit of the operation immediately before registered in the storage unit 203 is determined (S1003). If the input means of the immediately preceding operation is other than the motion detection means 106 (NO in S1003), nothing is done and the signal reception is awaited again.

  If the input means of the immediately preceding operation is the motion detecting means 106 (YES in S1003), the immediately preceding input operation is canceled (S1004). At this time, the operation input means and the elapsed time stored in the storage means 203 in the cancellation process of the input operation are reset to the initial state, and the measurement of the elapsed time is stopped.

  For example, when a movement of a part of the human body from the left to the right within the detection range of the motion detection means 106 is detected while the screen of FIG. 5A is displayed, the right button of the up / down / left / right button 101 is pressed. As in the case of the case, the cursor frame moves to the right, and the state shown in FIG.

  After this, if input cannot be detected from either the direct input means (up / down / left / right button 101 to cancel button 104) or the action detection means 106 and 10 seconds or more have passed, the human body detected by the action detection means which is the previous input has passed. A part of the left-to-right movement is not an operation intended by the user, that is, an erroneous input is determined, and the input is canceled (returning to the state of FIG. 5A).

  If the heating cooker is operated in a non-contact manner, the next input should be continued until the heating control is started. However, there is no next input even after a certain time (for example, 10 seconds) has passed. This is because it is considered that the user has operated unintentionally, for example, when the user has passed in front of the cooker, and the operation is detected by accident.

  On the other hand, when the right button of the up / down / left / right button 101 is pressed while the screen of FIG. 5 (a) is displayed, the cursor frame moves to the right in the same manner, but the state of FIG. After this, no input can be detected from either the direct input means (up / down / left / right button 101 to cancel button 104) or the action detection means 106, and nothing is done even after 10 seconds or more. This is because the process operated by the direct input means is determined to have been operated based on the user's intention.

  In this manner, the effectiveness of the operation can be determined by determining the type of the immediately preceding operation means and the elapsed time from the operation. As a result, an operation unintended by the user is automatically canceled, so that the user does not need to correct the operation and can prevent an erroneous operation / setting.

  In the present embodiment, when the input unit of the immediately preceding operation is the motion detecting unit 106, it has been described that the immediately preceding input operation is canceled (S1004). However, as shown in S1204 of FIG. The input of the return button 103 for returning to the operation screen may be detected, and the previous input operation may be canceled in the input control process (S302).

  In the present embodiment, when the input from the direct input means or the motion detection means is not detected for a certain period of time and the previous input is the input from the motion detection means, the input from the previous motion detection means is invalidated. However, the set time for determining that there is no input from any means may be changed depending on the state of the cooking device.

For example, in the menu screen shown in FIG. 5 and the setting screen shown in FIG. 6, it takes less time for the user to select the menu and change the setting value, so the setting time is set to 10 seconds, while in the recipe screen shown in FIG. Considering that the user prepares while watching the recipe screen, the set time is set to 5 minutes.

  In this way, by changing the set time depending on the state of the cooking device, the possibility of erroneously canceling the operation in a non-contact operation based on the user's intention can be reduced and the operation can be performed with peace of mind.

  In the present embodiment, it has been described that the elapsed time is measured even after the input is detected from the direct input unit. However, the elapsed time may be measured only after the input is detected from the operation detection unit. Since the elapsed time is always 0 after detection of input from the direct input means, the same control processing is possible without exceeding the set time.

  In addition, when the voice notification means is provided and the input from the immediately preceding motion detection means is invalidated, the user may be notified by the voice notification means. As a result, when the input from the immediately preceding motion detection means is an operation under the user's intention, the user can prevent the cancellation of the operation by performing some operation, and the previous motion detection If the input from the means is an operation unintended by the user, the user can be aware that an erroneous operation has occurred, and can pay attention to the operation thereafter.

(Embodiment 3)
Next, a third embodiment of the present invention will be described.

  The difference between the present embodiment and the first embodiment is that the control means 202 receives the input from the direct input means (up / down / left / right button 101 to cancel button 104), and then keeps the input from the motion detection means 106 constant. The point is that it is configured not to accept time.

  The schematic configuration diagram of the heating cooker and the control block diagram of the heating cooker in the third embodiment are the same as those in the first embodiment.

  The operation and action will be described below with reference to the control flowcharts of FIGS.

  Upon receiving an input signal from the direct input means (up / down / left / right button 101 to cancel button 104) (YES in S301), the control means 202 registers the direct input means as an operation input means in the storage means 203 (S1301). An input control process corresponding to each input means is performed (S302). Here, when the control unit 202 receives an input from the direct input unit (up / down / left / right button 101 to cancel button 104), the control unit 202 measures an elapsed time from the input reception.

  If the elapsed time has already been registered, it is reset and measurement starts again from zero. When the control unit 202 receives the detection signal from the operation detection unit 106 (NO in S301 and YES in S303), the control unit 202 determines the operation state of the heating unit 201 (S304).

  When the heating unit 201 is performing the heating control, the signal from the operation detecting unit 106 is discarded (YES in S304). At this time, the elapsed time during the counting is not reset and remains as it is. When the heating means 201 is not performing the heating control, the input means for the operation immediately before registered in the storage means 203 is determined (S1302).

  If the input means of the immediately preceding operation is a direct input means (up / down / left / right button 101 to cancel button 104) and a certain time has not elapsed since input (YES in S1302 and NO in S1303), the signal from the motion detection means 106 is discarded. To do. At this time, the elapsed time during the counting is not reset and remains as it is.

  On the other hand, if the input means of the immediately preceding operation is a direct input means (up / down / left / right button 101 to cancel button 104) and a certain time has elapsed since the input (YES in S1302 and YES in S1303), or the input of the immediately preceding operation If the means is not a direct input means (up / down / left / right button 101 to cancel button 104) (NO in S1302), the detection signal from the action detecting means 106 is received and the user's gesture action is determined (NO in S304, S305).

  In the gesture motion determination process (S305), the determination of each gesture motion is the same as S401 to 411 in FIG. After detecting the input of each button, the motion detection means 106 is registered as an operation input means in the storage means 203 (S1501), and input control processing is performed in S302.

  When the control unit 202 receives an input from the motion detection unit 106, the control unit 202 resets the elapsed time to an initial state and stops measuring the elapsed time.

  For example, when the right button of the up / down / left / right button 101 is pressed while the screen of FIG. 5 (a) is displayed, the cursor frame moves to the right and enters the state of FIG. 5 (b). Immediately after this, no particular action is taken even if a close stationary state of a part of the human body is detected within the detection range of the motion detection means 106.

  On the other hand, when 20 seconds have elapsed after the transition to FIG. 5B, when a close-up state of a part of the human body is detected within the detection range of the motion detection means 106, the menu is set in the same manner as when the start button 102 is pressed. And the range setting screen can be displayed (FIG. 5D).

  This is because it is judged that the operation by non-contact operation is unnecessary when the operation input can be performed directly by the input means, and the fact that the operation was performed without contact for a certain time (for example, 20 seconds) is used in front of the heating cooker. This is because it is considered that the user has been operated unintentionally, for example, when an operation is detected accidentally when the user passes by.

  On the other hand, when a movement of a part of the human body from the left to the right within the detection range of the motion detection means 106 is detected while the screen of FIG. 5A is displayed, the right button of the up / down / left / right button 101 is pressed. As in the case, the cursor frame moves to the right, and the state shown in FIG.

  Immediately after this, if a close proximity state of a part of the human body is detected within the detection range of the motion detection means 106, the menu is determined as the range in the same manner as when the start button 102 is pressed, and the range setting screen is displayed. (FIG. 5D). This is because it is determined that the continuous non-contact operation is performed based on the user's intention.

  In this manner, the effectiveness of the operation can be determined by determining the type of the immediately preceding operation means and the elapsed time from the operation. As a result, the non-contact operation becomes invalid in a state where the user can directly operate with the input means, and thus it is possible to further prevent an erroneous operation / incorrect setting unintended by the user.

(Embodiment 4)
Next, a fourth embodiment of the present invention will be described.

  The difference between the present embodiment and the first embodiment is further provided with a motion detection start instruction means, and the control means receives an input from the motion detection means when receiving a start instruction from the motion detection start instruction means. It is in the point comprised as follows.

FIG. 16 shows a control block diagram of the heating cooker in the fourth embodiment. FIG. 17A is a schematic configuration diagram of the heating cooker 100 when the operation detection start instruction unit 1601 is configured as a direct input unit having only a function. The operation detection start instructing unit 1601 includes buttons, a dial, a lever, and the like.

  The operation and action will be described below using the control flowchart of FIG.

  In FIG. 18, when the control means 202 receives the detection signal from the action detection start instruction means 1601 (NO in S301 and YES in S1801), it makes a transition to the action detection state (S1802). The motion detection state is a state in which an input from the motion detection means 106 is received. Note that the notification means 107 is turned on only when the operation is detected.

  When a detection signal is received from the motion detection means 106 (NO in S301, NO in 1801, and YES in S303), it is determined whether or not the motion detection state is set (S1803). If it is not in the motion detection state (NO in S1803), the signal from the motion detection means 106 is discarded. If it is in the motion detection state (YES in S1803), the motion state of the heating means 201 is determined (S304), the detection signal from the motion detection means 106 is received, and the user's gesture motion is determined (NO in S304). S305). Since the subsequent description is the same as that of the first embodiment, the description is omitted.

  Thereby, since the user can prohibit the detection of the non-contact operation when the non-contact operation is unnecessary, it is possible to more surely prevent an erroneous operation / incorrect setting which is not intended by the user.

  In addition, the schematic block diagram of the heating cooker 100 when the operation detection start instruction unit 1601 is configured as one of the menu items is the same as FIG. The user can instruct the start of motion detection by directly selecting the menu item corresponding to the motion detection start instruction from the menu items displayed on the display means 105 using the input means (up / down / left / right button 101, start button 102). it can.

  FIG. 17B is a schematic configuration diagram of the heating cooker 100 when the operation detection start instruction unit 1601 is configured by a second operation detection unit different from the operation detection unit 106. The motion detection start instructing unit 1601 is a device that detects a motion of a part of the human body in a non-contact manner, like the motion detection unit 106. In the present embodiment, a single thermopile infrared sensor is used to detect the proximity of a human hand. The motion detection start instruction means 1601 can instruct the start of motion detection by detecting the hand holding (proximity of the hand).

  As a result, when an operation is suddenly required during preparation, even if the hand is dirty, it is possible to instruct the start of non-contact operation detection and perform the operation without contact.

  In addition, not only one thermopile type infrared sensor but a plurality of sensors may be used to detect a complicated operation, or another sensor may be used.

  Further, it is possible to regard a predetermined motion detected from the motion detection means 106 as a motion detection start instruction without providing a special means for motion detection start instruction.

  The control unit 202 determines that an operation detection start instruction has been received when a predetermined operation that cannot be performed by a normal input operation, for example, ten consecutive hand movements or rotational movements, is detected in the input from the movement detection unit 106. (NO in S301 and YES in S1801), the state transitions to the operation detection state (S1802).

  Thereby, the start instruction | indication of non-contact operation can be received, without providing the special means for an operation | movement detection start instruction | indication, and the structure of the heating cooker 100 can be simplified.

  The operation detection state can be canceled by providing an operation detection cancellation instruction means or a menu item for instructing the operation detection cancellation, and allowing the user to directly cancel the operation, or at the start of heating control, or It may be automatically canceled when the door is opened and closed after cooking.

  In addition, in the description of the above Embodiments 1-4, although the heating cooker demonstrated as a microwave oven, a rice cooker, an electromagnetic induction heating cooker, etc. may be sufficient.

  As described above, the cooking device according to the present invention, the heating cooker operating method, and the program can improve the usability because the user can operate the cooking device even when the hand remains dirty. Therefore, it is effective for cooking appliances.
