Description

[Technical Field]

[0001] The present invention relates to a cooking system and a cooking appliance used in the cooking system. [Background technology]

[0002] Conventionally, cooking appliances such as gas stoves that can be operated by voice recognition are known, as seen in Patent Document 1. Such cooking appliances allow a user to operate the cooking appliance by non-contact actions even when both hands are unavailable during cooking.

[0003] Furthermore, Patent Document 2 discloses a voice recognition system that eliminates noise during voice recognition in order to prevent erroneous voice recognition. If such technology is used in a cooking appliance such as that disclosed in Patent Document 1, it is thought that the cooking appliance can be operated by voice while reducing erroneous voice recognition even in a noisy environment such as a kitchen. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2020-003076 [Patent Document 2] JP 2015-069063 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, even in a cooking device that combines Patent Document 1 and Patent Document 2, if there are multiple heating means, there is a problem in that it is difficult to reliably determine which heating means a contactless input issued by the user is directed to. In such cases, a malfunction may occur in which a heating means that the user does not intend to use is controlled. Even if the malfunction occurs infrequently, if it occurs even several times while using a cooking device with multiple heating means, it will cause inconvenience and stress for the user, and there is a problem in that it will lack marketability.

[0006] Furthermore, there is a problem that if a heating means that the user does not intend to use is mistakenly operated, items other than cooking utensils (such as pots and kettles) placed near the heating means that the user does not intend to use (such as tableware or dishcloths made of resin or paper) may be heated, which could cause a fire.

[0007] The present invention was developed to solve these problems, and aims to provide a cooking device and cooking system that allows a user to reliably operate multiple heating means even when the user operates the multiple heating means in a non-contact manner. [Means for solving the problem]

[0008] In order to achieve the above object, the cooking system of the present invention has the following invention-specific features.

[0009] The cooking system of the present invention comprises: A plurality of heating means; a non-contact operation input means for accepting a non-contact operation; a non-contact operation control means for recognizing the non-contact operation input to the non-contact operation input means and controlling the heating means in response to the non-contact operation; a use intention determination means for determining whether or not a user intends to use each of the plurality of heating means; a notification means for issuing a predetermined notification when the intended use determination means determines that there is a heating means that is intended to be used, The non-contact operation control means controls the heating means determined to have the intended use in response to the non-contact operation.

[0010] The cooking system is configured to determine whether a user intends to use each of a plurality of heating means, and to accept non-contact operation of a heating means determined to be intended for use by the user among the plurality of heating means. This makes it possible to reliably operate the intended heating means to be controlled, and to prevent the operation of heating means that the user does not intend to use.

[0011] In addition, according to the cooking system, the notification means is configured to issue a predetermined notification when a heating means is determined to be in use, so that the user can reliably recognize the heating means to be controlled and that the intended use of the heating means can be reduced.

[0012] In the cooking system described above, It is preferable that the notification means performs the first notification while the usage intention determination means determines that the user has an intention to use the device.

[0013] According to this cooking system, the notification means is configured to issue a first notification while it is determined that the user intends to use the cooking device. This allows the user to constantly recognize which heating devices are available for receiving input via the non-contact operation input means. Furthermore, if a heating device that is not intended to be used is notified in the first notification mode due to erroneous recognition, the user can quickly recognize that the non-contact operation has been erroneously recognized. Therefore, this cooking system reduces the risk of a heating device that is not intended to be used being erroneously operated due to a non-contact operation, and allows for reliable non-contact operation of a heating device that is intended to be used.

[0014] In any one of the cooking systems described above, It is preferable that the notification means performs a second notification different from the first notification while the usage intention determination means is determining whether or not the user intends to use the device.

[0015] According to this cooking system, the notification means is configured to issue a second notification while determining the user's intended use. In this way, the cooking system has a predetermined determination time to prevent erroneous recognition of intended use. In this case, by issuing a notification different from the first notification during the determination, the user can recognize that the intended use determination means has accepted the intended use. If an unintended heating means is notified in the form of the second notification due to erroneous recognition, the user can recognize the system's erroneous recognition before a non-contact operation is accepted. Therefore, this cooking system reduces the risk of an unintended heating means being erroneously operated due to a non-contact operation, and enables a heating means that is intended to be used to be reliably operated non-contact.

[0016] In any one of the cooking systems described above, The non-contact operation control means preferably controls so as to prohibit a predetermined non-contact operation on the heating means for which it has been determined by the usage intention determination means that there is no intention to use.

[0017] According to this cooking system, a predetermined non-contact operation is prohibited for a heating means determined to be unintended for use. Here, the predetermined non-contact operation includes operations that increase the likelihood of causing a fire, such as heating or increasing the degree of heating. Therefore, this cooking system can reduce malfunction of a heating means that is unintended for use due to a non-contact operation.

[0018] In any one of the cooking systems described above, The intended use determining means is preferably provided separately from the heating means determined to have an intended use by the intended use determining means. Heating and cooking system.

[0019] In this cooking system, the intention-of-use determination means is provided separately from the heating means determined to have an intended use. Therefore, the intention-of-use determination means can detect the user from a bird's-eye view. Therefore, this cooking system can detect the user's intention of use over a wide range of the kitchen space and can directly detect the user's behavior, making it possible to detect the user's intention of use over a wide range and with high accuracy.

[0020] In any one of the cooking systems described above, The usage intention determining means is preferably configured in a form that can be worn by the user.

[0021] According to this cooking system, the intended use determination means is configured to be wearable by the user. Therefore, a single intended use determination means can determine the intended use of each of multiple heating means (e.g., a microwave oven and a gas stove) installed at different locations in the kitchen space. Therefore, this cooking system can detect the intended use of the user over a wide area of ​​the kitchen space.

[0022] In any one of the cooking systems described above, The plurality of heating means preferably comprises a plurality of cooking devices.

[0023] According to this cooking system, contactless operation can be performed for each of a plurality of cookers by indicating the intended use. Therefore, when cooking using a plurality of cookers, the user can reduce the risk of a cooker not intended to be used malfunctioning due to contactless operation, and can reliably operate a cooker intended to be used contactlessly.

[0024] In any one of the cooking systems described above, It is preferable that the plurality of heating means are provided in the same cooking device.

[0025] According to this cooking system, it is possible to perform contactless operation for each of a plurality of heating means arranged in close proximity by indicating the intended use. Therefore, according to this cooking system, it is possible to reduce the malfunction of a heating means that is not intended to be used due to contactless operation for each of a plurality of heating means arranged in close proximity, and to reliably perform contactless operation for a heating means that is intended to be used.

[0026] In order to achieve the above object, the cooking device of the present invention has the following inventive features.

[0027] The cooking device of the present invention comprises: A plurality of heating means; a non-contact operation input means for accepting a non-contact operation; a non-contact operation control means for recognizing the non-contact operation input to the non-contact operation input means and controlling the heating means in response to the non-contact operation; a use intention determination means for determining whether or not a user intends to use each of the plurality of heating means; a notification means for issuing a predetermined notification when the intended use determination means determines that there is a heating means that is intended to be used, The non-contact operation control means controls the heating means determined to have the intended use in response to the non-contact operation.

DETAILED DESCRIPTION OF THE INVENTION

[0029] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0030] Fig. 1 is a schematic diagram of a cooking system 1 according to one embodiment of the present invention. Fig. 2 is a schematic diagram of the internal configuration of a cooking device 10, intended use determination means 20, non-contact operation input means 21, non-contact operation control means 22, and notification means 23 that constitute the cooking system 1. Referring to Fig. 1, the cooking system 1 mainly comprises a cooking device 10 equipped with heating means and the like, and intended use determination means 20.

[0031] In this embodiment, the cooking appliance 10 is, for example, a gas stove, and has a plurality of heating means (heating means 5 to 8). FIG. 1 shows a stove burner and a grill burner as examples of the heating means. In this embodiment, the heating means 8 as a grill burner is provided inside a grill chamber 2a provided inside a grill 2 provided in the center of the front side of the cooking appliance 10. The grill 2 opens and closes the front opening of the grill chamber 2a provided inside the cooking appliance 10 when putting an object to be heated into or taking out of the grill chamber 2a.

[0032] The cooking device 10 of this embodiment is a built-in gas stove that is incorporated into the countertop W of a system kitchen, and is equipped with a box-shaped stove body 3 with an open top. A top plate 4 is provided on top of the stove body 3, and heating means 5 to 7 as stove burners supported by the stove body 3 are exposed upward from the top plate 4.

[0033] In Fig. 1, a cooking vessel P is placed on top of the heating means 7 on the right side. Although a stove burner and a grill burner are shown as examples of the heating means 5 to 8, the present invention is not limited to these, and heating means such as an induction heater, a microwave oven, a rice cooker, a microwave oven, and a pot may also be subject to control as described below as the heating means of the present invention.

[0034] As described in this embodiment, the plurality of heating means 5 to 8 may be provided in the same cooking device 10, or the plurality of heating means 5 to 8 may be configured from the plurality of cooking devices 10. Furthermore, the number of heating means is not particularly limited.

[0035] Furthermore, on both sides of the grill 2 on the front side of the cooking appliance 10, there are provided touch operation input means for receiving touch operations for the respective heating means 5 to 8. As the touch operation input means, Fig. 1 shows on / off buttons 13a to 13d for the respective heating means 5 to 8 and a power switch 13e.

[0036] Each of the extinguishing buttons 13a to 13d is a push-type button, and by pushing it once from the extinguishing position shown in Figure 1 where it is recessed into the front panel and then releasing it, it will protrude to the combustion position in front of the front panel, and in this state it can be rotated to adjust the flame intensity.

[0037] Contact operation signals from the power switch 13e and the operation detection switches (not shown) of the respective on / off buttons 13a to 13d of the heating means 5 to 8 are input to contact operation control means as a control section including a microcomputer, together with signals from the respective flame detection elements of the heating means 5 to 8. The contact operation control means then controls the igniter, main valve, and each gas valve device (not shown).

[0038] 2, in addition to the contact operation input means and the contact operation control means, the cooking system 1 is equipped with a non-contact operation input means 21 that accepts non-contact operations, and a non-contact operation control means 22 as a control unit including a microcomputer that recognizes the non-contact operations input to the non-contact operation input means 21 and controls the heating means 5 to 8 in accordance with the non-contact operations. The non-contact operation input means 21 and the non-contact operation control means 22 are connected to the cooking appliance 10 by wired communication or wireless communication.

[0039] Non-contact operations include, for example, voice, gestures, eye movements, facial expressions, and brain waves. Non-contact operation input means 21 is a device that recognizes the above-mentioned non-contact operations, such as a voice input device, an imaging device, or a brain wave acquisition device. Non-contact operation control means 22 controls the igniter, main valve, and each gas valve device according to the non-contact operations input to non-contact operation input means 21 through controls described below.

[0040] Next, the intended use determination means 20 will be described. The intended use determination means 20 determines whether or not the user intends to use each of the multiple heating means. The intended use determination means 20 is connected to the cooking appliance 10 via wired or wireless communication. The intended use determination means 20 is, for example, a camera unit including a visible light camera or an infrared camera. In the embodiment shown in FIG. 1 , the intended use determination means 20 is attached to the wall between the cooking appliance 10 and the range hood 30. In addition to the above-mentioned attachment position, the intended use determination means 20 may be attached to the range hood, a part of the cooking appliance 10, or worn by the user in the form of goggles or the like. Furthermore, the intended use determination means 20 may be shared with a camera installed in the range hood to monitor the cooking status of the cooking appliance 10. The intended use determination means 20 does not necessarily have to be installed facing the user. In this case, the intended use determination means 20 may be configured to detect the intended use of a user located in another direction by providing a mirror or the like. That is, the usage intention determining means 20 may be provided separately from the heating means 5 to 8, may be configured integrally with the heating means 5 to 8, or may be configured in a form that can be worn by the user (for example, goggles).

[0041] For example, the usage intention determination means 20 recognizes the user's line of sight and then determines the user's intention to use each of the heating means 5 to 8. Alternatively, the usage intention determination means 20 may determine the usage intention by combining multiple sensors (for example, a human presence sensor and a temperature sensor that measures the temperature of the food being cooked). The usage intention may also be determined by machine learning based on data acquired using these sensors.

[0042] Note that a plurality of usage intention determination means 20 may be provided. Furthermore, usage intention determination means 20 attached to one heating means may be configured to determine the usage intention of another heating means. For example, usage intention determination means 20 attached to a microwave oven (one heating means) may be configured to control a stove burner and a microwave oven (another heating means and the one heating means), respectively.

[0043] The cooking system 1 is provided with a notification means 23. The notification means 23 is configured to issue a predetermined notification when there is a heating means determined to be intended for use by the intention-to-use determination means 20. In this embodiment, the notification means 23 is configured integrally with the heating means 5 to 8, but it may be provided separately from the heating means 5 to 8, or may be configured in a form that can be worn by the user (for example, goggles). The notification means 23 may issue a notification by an auditory method (for example, sound), a visual method (for example, light), or a tactile method (for example, vibration), or may issue a notification by a combination of these.

[0044] Next, a method for controlling the cooking appliance 10 by non-contact operation according to the present invention will be described.

[0045] FIG. 3 is a flowchart showing one embodiment of the method for controlling the cooking appliance 10 by non-contact operation of the present invention. Using FIG. 3, a case where the heating means 7 is operated by non-contact will be described as an example. Note that the processing in FIG. 3 is performed independently for each of the plurality of heating means 5 to 8. When the user wishes to operate at least one of the plurality of heating means 5 to 8, the user performs a predetermined operation to turn on (start) the operation of the cooking appliance 10, thereby instructing the execution of the operation (FIG. 3 / START). Here, the predetermined operation to turn on the operation may be a contact operation or a non-contact operation.

[0046] When the operation of the cooking device 10 is started in this manner, in STEP 1, the intention-to-use determination means 20 determines whether or not there is an intention to use one of the heating means 5 to 8 of the cooking device 10 (heating means 7 in this embodiment).

[0047] If the determination result is positive (FIG. 3 / STEP 1 YES), in STEP 2, the notification means 23 issues a first notification. Here, the first notification may be, for example, keeping the display (LED) indicating the heating means 7 lit, repeatedly outputting a sound indicating the heating means 7, or outputting a beep sound indicating the heating means 7 with a different output pattern or tone. Note that the first notification may be issued by the notification means 23 intermittently while there is an intention to use the device, or may be issued over a predetermined period of time from the start of STEP 2, or may be issued a predetermined number of times from the start of STEP 2.

[0048] Next, in STEP 3, it is determined whether or not there is a non-contact operation signal through the non-contact operation input means 21 to the heating means 7. If the determination is negative (FIG. 3 / STEP 3: NO), the process returns to just before STEP 1, and the processes from STEP 1 onwards are executed again.

[0049] If the determination is affirmative (FIG. 3 / STEP 3 YES), in STEP 4, the heating means 7 is controlled in response to the contactless operation signal through the contactless operation control means 22. This ensures that only the heating means that the user intends to use are subject to contactless operation, thereby enabling reliable operation of multiple heating means while reducing malfunctions.

[0050] Next, in STEP 5, it is determined whether or not a predetermined termination operation has been performed. The predetermined termination operation refers to an operation for turning off (terminating) the operation of the cooking appliance 10. The operation may be a contact operation or a non-contact operation.

[0051] If the determination is affirmative (FIG. 3 / STEP 5 YES), the operation of the cooking device 10 is terminated (FIG. 3 / END). On the other hand, if the determination is negative (FIG. 3 / STEP 5 NO), the process proceeds to identifier A, and the processing from STEP 1 onwards is executed again.

[0052] If it is determined in STEP 1 that there is no intention to use the heating means 7 through the intention-to-use determination means 20 (FIG. 3 / STEP 1··NO), it is determined in STEP 6 whether or not there is a contactless operation signal through the contactless operation input means 21 to the heating means 7. If the determination is negative (FIG. 3 / STEP 6··NO), the process proceeds to identifier A, and the processing from STEP 1 onwards is executed again.

[0053] If the determination result is positive (FIG. 3 / STEP 6··YES), it is determined in STEP 7 whether the non-contact operation signal is a predetermined operation from the viewpoint of safety. The predetermined operation in STEP 7 is an operation that increases the probability of causing a fire if not intended by the user, such as heating, increasing the degree of heating of the heating means 7, or extending the heating time of the heating means 7.

[0054] If the determination in STEP 7 is affirmative (FIG. 3 / STEP 7·YES), in STEP 8, the non-contact operation control means 22 prohibits the heating means 7 from being controlled in response to the non-contact operation signal. At this time, the notification means 23 may notify the user that there is no intention to use the heating means. This prohibits the control of the heating means, which can be highly dangerous, when there is no intention to use the heating means, thereby ensuring safety and enabling the control of the multiple heating means 5 to 8. Next, the process proceeds to STEP 5, where the subsequent processes are executed.

[0055] If the determination in STEP 7 is negative (FIG. 3 / STEP 7··NO), in STEP 9, the heating means 7 is controlled in response to the non-contact operation signal via the non-contact operation control means 22. This allows the heating means 7 to be extinguished, the degree of heating reduced, the heating time shortened, the current setting and timer time checked, or other safety measures to be taken to control the multiple heating means 5 to 8, even if the user does not intend to use the heating means 7. Next, the process proceeds to STEP 5, and the subsequent processes are executed.

[0056] The determination in STEP 5 may be made immediately after any of STEPs 1 to 9. This allows the user to perform the shutdown operation of the cooking appliance 10 at any timing. Furthermore, the control by the contact operation may be performed in parallel with any of STEPs 1 to 9, and then the heating means 7 may be controlled. In other words, even if the intention of use is not determined, the heating means 7 may be controlled in parallel with the control by the contact operation.

[0057] Next, an embodiment of the determination method in STEP 1 will be described.

[0058] FIG. 4 is a flowchart showing one embodiment of a method for determining whether there is an intention to use the heating means 7 through the intention-to-use determination means 20 in STEP 1. STEPs 11 to 13 in FIG. 4 correspond to STEP 1 in FIG. 3. In STEP 11, it is determined whether the user's line of sight PV is within the designated range DA. FIG. 5 is a schematic diagram showing the relationship between the line of sight PV and the designated range DA in the cooking system 1. The line of sight PV is the user's line of sight, and is detected by the intention-to-use determination means 20. The designated range DA is the range within which the user's line of sight PV is expected to be present when controlling the heating means 7 during cooking, such as the vicinity of the heating means 7, the vicinity of the cooking container P, or the vicinity of an output device that notifies the user of the heating output of the heating means 7.

[0059] If the determination is affirmative (FIG. 4 / STEP 11: YES), in STEP 12, the notification means 23 issues a second notification. Here, the second notification is a notification in a manner different from the first notification described above, and may include continuously flashing the display (LED) indicating the heating means 7, repeatedly outputting a sound indicating that the intended use of the heating means 7 is being determined, or outputting a beep sound indicating that the intended use of the heating means 7 is being determined with a different output pattern or tone. Note that the second notification may be issued by the notification means 23 intermittently while the intended use is being determined, or may be issued only for a predetermined period from the start of STEP 12, or may be issued a predetermined number of times from the start of STEP 12, or may be issued by the notification means 23 intermittently until a predetermined period of time has elapsed in STEP 13, which will be described later.

[0060] Next, in STEP 13, the time during which the line of sight PV is within the designated range DA is measured, and it is determined whether a predetermined time has elapsed. Note that the timing is preferably started immediately after STEP 11 or immediately before STEP 12.

[0061] If the determination is affirmative (FIG. 4 / STEP 13 YES), it is determined in STEP 14 that the heating means 7 is intended to be used (FIG. 4 / STEP 14), and the processing from STEP 3 onward is executed. On the other hand, if the determination is negative (FIG. 4 / STEP 13 NO), the process returns to STEP 11 and the processing from STEP 11 onward is executed again.

[0062] If the determination in STEP 11 is negative (FIG. 4 / STEP 11·NO), it is determined that there is no intention to use the heating means 7 (FIG. 4 / STEP 15), and the processing from STEP 6 onwards is executed. If it is determined that there is no intention to use the heating means 7, the clock is reset.

[0063] This allows the user to operate the plurality of heating means 5 to 8 reliably while reducing malfunctions, even when the user operates the plurality of heating means 5 to 8 in a non-contact manner.

[0064] In the above embodiment, the eye gaze is used as a means for determining the intended use, but the present invention is not limited to this, and the intended use may be determined by any method obvious to those skilled in the art. For example, the intended use may be determined by whether the user's face is facing the heating means, whether the user has placed a pot on the trivet, whether a human presence sensor has detected the addition of food and there has been a significant temperature change in the food, etc.

[0065] In the above embodiment, the contact operation control means and the non-contact operation control means 22 are configured separately, but this is not limited to this, and they may be configured by the same control means as long as contact operation and non-contact operation are distinguished.

[0066] Although one embodiment of the present invention has been described above, it is clear that the present invention is not limited to the above-described embodiment or example, and that the scope of the present invention can be modified or altered within a range that is obvious to a person skilled in the art. It is also clear that the scope of the present invention is not limited to the above-described embodiment or example, but also includes modifications and alterations thereof.
