[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-90958 Summary of the Invention [Problem to be solved by the invention]
[0004] Microwave ovens mounted on vehicles are subject to the effects of vibrations while the vehicle is running and sudden braking, for example, and therefore require different safety measures than microwave ovens installed indoors.

[0010] Hereinafter, embodiments of the present disclosure will be described in detail with appropriate reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed descriptions of well-known matters and redundant descriptions of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.
[0011] (Embodiment 1) <Vehicle and microwave configuration> FIG. 1 is a block diagram showing an example of the configuration of a vehicle 1 and a microwave oven 30 according to the first embodiment.
[0012] 1, the vehicle 1 includes an ECU 11, an engine 12, an accelerator sensor 13, a brake sensor 14, a vehicle speed sensor 15, a shift lever 16, brake lights 17, a display device 18, and a microwave oven 30. If the vehicle 1 is an electric vehicle or a hybrid vehicle, a motor may be provided in place of or in addition to the engine 12.
[0013] The ECU 11 transmits and receives vehicle information to and from an engine 12, an accelerator sensor 13, a brake sensor 14, a vehicle speed sensor 15, a shift lever 16, brake lights 17, a display device 18, and a microwave oven 30 via an in-vehicle network 19. Examples of the in-vehicle network 19 include a Controller Area Network (CAN), a Local Interconnect Network (LIN), and FlexRay.
[0014] The vehicle information may include the rotation speed of the engine 12. The vehicle information may include the accelerator opening amount measured by the accelerator sensor 13. The vehicle information may include the brake depression amount measured by the brake sensor 14. The vehicle information may include information indicating the state of the shift lever 16. The information indicating the state of the shift lever indicates, for example, whether the shift lever is in park, drive, reverse (back), or neutral. The vehicle information may include information indicating the state of the brake lamps 17. The information indicating the state of the brake lamps indicates, for example, whether the brake lamps are off, on, or flashing. The vehicle information may include information indicating the speed of the vehicle measured by the vehicle speed sensor 15.
[0015] Based on the acquired vehicle information, the ECU 11 performs various controls on the vehicle 1. Based on the acquired vehicle information, the ECU 11 also displays various information on the display device 18. For example, the ECU 11 displays the speed, engine RPM, the state of the shift lever, etc. on the display device 18.
[0016] As shown in FIG. 1, microwave oven 30 includes magnetron 31, door 32, door lock unit 33, temperature sensor 34, acceleration sensor 35, operation unit 36, display unit 37, speaker 38, communication unit 39, and control unit 40.
[0017] Magnetron 31 emits microwaves into the interior of microwave oven 30, and heats at least a portion of an object placed inside the oven (i.e., an object that can be heated by microwaves). Hereinafter, an object that can be heated by microwaves placed inside the oven will be referred to as a heating target.
[0018] Door 32 is configured to close the interior of microwave oven 30 and can be opened and closed by a user (for example, a passenger).
[0019] The door lock unit 33 has a mechanism for locking or unlocking the door 32. When the door 32 is locked by the door lock unit 33, the door 32 cannot be opened. When the door 32 is unlocked (i.e., released from the lock) by the door lock unit 33, the door 32 can be opened.
[0020] The temperature sensor 34 measures the temperature of the object to be heated inside the refrigerator or the temperature of the entire refrigerator.
[0021] Acceleration sensor 35 measures the acceleration occurring in microwave oven 30. Because microwave oven 30 is mounted on vehicle 1, acceleration may occur in microwave oven 30 due to tilt or vibration, sudden braking, sudden acceleration, etc. of vehicle 1. Therefore, the occurrence of tilt or vibration, etc. of vehicle 1 can be detected from the acceleration measured by acceleration sensor 35.
[0022] The operation unit 36 accepts user operations for the microwave oven 30. Examples of components of the operation unit 36 include buttons and dials.
[0023] Display unit 37 displays information relating to the operation, behavior, status, etc. of microwave oven 30.
[0024] The speaker 38 outputs sounds related to the operation, behavior, status, etc. of the microwave oven 30.
[0025] The communication unit 39 receives vehicle information and the like from the ECU 11 and the like mounted on the vehicle 1 via the in-vehicle network 19 .
[0026] Control unit 40 controls the behavior of microwave oven 30 based on operations input to operation unit 36. For example, control unit 40 operates magnetron 31 based on various setting values (e.g., wattage, heating time, heating temperature, etc.) input by the user through operation unit 36.
[0027] Furthermore, control unit 40 controls the behavior of microwave oven 30 based on the vehicle information received by communication unit 39. For example, control unit 40 controls door lock unit 33 to lock or unlock the door based on the vehicle information. Further processing performed by control unit 40 will be described as appropriate.
[0028] A microwave oven 30 mounted on a vehicle 1 is subject to vibrations and sudden braking while the vehicle 1 is traveling, and therefore requires different safety measures than a microwave oven installed indoors. For example, if the driver suddenly brakes while the microwave oven 30 is heating an object with the magnetron 31 operating, causing the door 32 of the microwave oven 30 to open and the object to be heated to fly out of the microwave oven 30, this poses a danger to the driver and passengers of the vehicle 1. On the other hand, if the microwave oven 30 were completely unusable while the vehicle 1 is traveling, the convenience of the microwave oven 30 for passengers would be greatly reduced. For example, in camper vans and future autonomous driving vehicles, it is expected that there will be a need to use the microwave oven 30 to heat an object to be heated even while the vehicle 1 is traveling. Therefore, this embodiment discloses a technology that can achieve both safety and convenience for the microwave oven 30 mounted on the vehicle 1. This will be described in detail below.
[0029] <Total microwave oven processing> FIG. 2 is a flowchart showing an example of the overall process of microwave oven 30 according to the first embodiment.
[0030] The control unit 40 acquires vehicle information and determines whether the shift lever 16 is in the parking position based on information indicating the state of the shift lever 16 included in the vehicle information (S101). In other words, the control unit 40 determines whether the vehicle 1 is stopped.
[0031] When the control unit 40 determines that the shift lever 16 is in the parking position (S101: YES), it displays the liquid mode and other modes (e.g., solid mode, defrost mode, etc.) on the display unit 37 as heating mode options, and allows the user to select one (S102). Note that when the shift lever 16 is not in the parking position (S101: NO), the control unit 40 may not allow the liquid mode to be selected as a heating mode option. In this case, the user cannot select the liquid mode.
[0032] If the user selects the liquid mode (S102: YES), the control unit 40 operates the magnetron 31 to start heating the heating target in the liquid mode (S103).
[0033] The control unit 40 acquires the vehicle information and determines whether the shift lever 16 is in the parking position based on the information indicating the state of the shift lever included in the vehicle information (S104).
[0034] If the shift lever 16 is not in the park position (S104: NO), the control unit 40 stops the operation of the magnetron 31, forcibly stops heating (S105), and ends this process. For example, the control unit 40 forcibly stops heating when the shift lever 16 is in drive or reverse (back). This is because the object to be heated contains liquid, and when the vehicle 1 starts moving, vibrations or sudden braking while moving can cause the heated liquid to splash or spill inside the compartment, which is dangerous.
[0035] When the control unit 40 determines that the shift lever 16 is in the parking position (S104: YES), the control unit 40 determines whether the heating is complete (S106). For example, when the heating time set by the user has expired or when the temperature of the object to be heated has reached the temperature set by the user, the control unit 40 determines that the heating is complete.
[0036] If the control unit 40 determines that the heating is not completed (S106: NO), the process returns to step S104, and if the control unit 40 determines that the heating is completed (S106: YES), the process ends.
[0037] As described above, microwave oven 30 mounted on vehicle 1 does not heat an object to be heated, including a liquid, when shift lever 16 is not in the park position or when shift lever 16 is no longer in the park position, since vehicle 1 may be moving. This allows the object to be heated, including a liquid, to be heated safely.
[0038] Microwave oven 30 may have a function to automatically detect whether the object to be heated contains liquid. In this case, when control unit 40 detects that the object to be heated contains liquid, it determines whether shift lever 16 is in the parking position, and starts heating if it determines that shift lever 16 is in the parking position, but does not start heating if it determines that shift lever 16 is not in the parking position.
[0039] Next, a process will be described for when it is determined in step S101 that the shift lever 16 is not in the parking position (S101: NO), or when the user selects another mode in step S102 (S102: NO).
[0040] The control unit 40 operates the magnetron 31 to start heating the heating target in the other mode (S111).
[0041] The control unit 40 executes a sudden stop detection process (S112). Details of the sudden stop detection process will be described later (see FIG. 3), but in the sudden stop detection process, if a sudden stop is detected, the first detection flag is set to ON, and if a sudden stop is not detected, the first detection flag is set to OFF.
[0042] The control unit determines whether or not the first detection flag for the sudden stop detection process is ON (S113).
[0043] If the first detection flag of the sudden stop detection process is ON (S113: YES), control unit 40 controls door lock unit 33 to lock microwave oven door 32 (S151), and the process proceeds to step S112.
[0044] If the first detection flag of the sudden stop detection process is OFF (S113: NO), the control unit 40 executes the auto-cruise detection process (S114). Details of the auto-cruise detection process will be described later (see FIG. 3), but in this auto-cruise detection process, if auto-cruise is set, the second detection flag is set ON, and if auto-cruise is not set, the second detection flag is set OFF.
[0045] The control unit 40 determines whether or not the second detection flag for the auto-cruise determination process is ON (S115).
[0046] If the second detection flag of the auto-cruise determination process is OFF (S115: NO), control unit 40 executes temperature and speed detection process (S116). Details of the temperature and speed detection process will be described later (see FIG. 5), but in the temperature and speed detection process, if the temperature of the heating object inside microwave oven 30 is equal to or higher than a predetermined threshold and the speed of vehicle 1 is equal to or higher than the predetermined threshold, a fourth detection flag is set ON, and if not, the fourth detection flag is set OFF.
[0047] The control unit 40 determines whether the fourth detection flag for the temperature and speed detection process is ON (S117).
[0048] If the fourth detection flag of the temperature and speed detection process is ON (S117: YES), control unit 40 controls door lock unit 33 to lock door 32 of microwave oven 30 (S151), and the process proceeds to step S112.
[0049] If the second detection flag of the auto-cruise detection process is ON (S115: YES), or if the fourth detection flag of the temperature and speed detection process is OFF (S117: NO), control unit 40 executes microwave oven tilt detection process (S121). Details of the microwave oven tilt detection process will be described later (see FIG. 6), but in this microwave oven tilt detection process, if microwave oven 30 is tilted or if microwave oven 30 is vibrating greatly, a third detection flag is set ON, and if not, the third detection flag is set OFF.
[0050] Control unit 40 determines whether or not the third detection flag for the microwave oven tilt detection process is ON (S122).
[0051] If the third detection flag for the microwave oven tilt detection process is ON (S122: YES), control unit 40 controls door lock unit 33 to lock door 32 of microwave oven 30 (S151), and the process proceeds to step S112.
[0052] If the third detection flag for the microwave oven tilt detection process is OFF (S122: NO), control unit 40 controls door lock unit 33 to unlock door 32 of microwave oven 30 (S152), and the process proceeds to step S153.
[0053] In step S153, the control unit 40 determines whether or not heating of the heating target has been completed (S153).
[0054] If the heating is not completed (S153: NO), the control unit 40 returns the process to step S112, and if the heating is completed (S153: YES), the control unit 40 stops the operation of the magnetron 31 and ends this process.
[0055] When the control unit 40 locks the door 32 in step S151, it is not necessary for the control unit 40 to unlock the door 32 until a predetermined period of time has elapsed, even if a situation arises in which unlocking of the door 32 in step S152 can be executed.
[0056] Furthermore, the order of the processes shown in Fig. 2 is an example, and the control unit 40 may perform the processes in an order different from the order shown in Fig. 2. The control unit 40 is not required to implement all of the processes shown in Fig. 2, and may implement some of the processes shown in Fig. 2.
[0057] <Sudden stop detection processing> 3 is a flowchart showing an example of the sudden stop detection process according to Embodiment 1. Next, the process of step S112 will be described in detail with reference to FIG.
[0058] The control unit 40 acquires the vehicle information, and determines whether the traveling speed of the vehicle 1 is equal to or greater than a predetermined threshold (for example, 60 km / h) based on information indicating the speed of the vehicle 1 included in the vehicle information (S201).
[0059] If the driving speed is equal to or greater than a predetermined threshold (S201: YES), the control unit 40 acquires vehicle information and determines whether the brake lights are on or not based on information indicating the state of the brake lights of the vehicle 1 contained in the vehicle information (S202).
[0060] If the brake lights are on (S202: YES), control unit 40 turns on the first detection flag (S203), and returns to the processing of step S112 and subsequent steps in FIG. 2. That is, control unit 40 turns on the first detection flag when the brakes are applied suddenly while vehicle 1 is traveling at a high speed. In this case, door 32 of microwave oven 30 is locked in step S151 in FIG. 2. This prevents door 32 of microwave oven 30 from opening and the object to be heated from flying out when vehicle 1 suddenly stops.
[0061] If the traveling speed is less than the predetermined threshold (S201: NO) or if the brake lights are not on (S202: NO), the control unit 40 turns off the first detection flag (S204) and returns to the processing from step S112 onwards in FIG. 2.
[0062] Note that microwave oven 30 may implement only the sudden stop detection process (S112), and not implement the auto-cruise detection process (S114), the temperature and speed detection process (S116), and the microwave oven tilt detection process (S121). In this case, control unit 40 may control door lock unit 33 to lock door 32 instead of turning the first detection flag ON in step S203, and may control door lock unit 33 to unlock door 32 instead of turning the first detection flag OFF in step S204.
[0063] <Auto-cruise detection processing> 4 is a flowchart showing an example of the auto-cruise detection process according to Embodiment 1. Next, the process of step S114 will be described in detail with reference to FIG.
[0064] The control unit 40 acquires vehicle information, and determines whether the auto-cruise mode of the vehicle 1 is ON based on information indicating the state of the auto-cruise mode of the vehicle 1 included in the vehicle information (S301).
[0065] If the auto-cruise mode is ON (S301: YES), the control unit 40 turns ON the second detection flag for the auto-cruise detection process (S302), and returns to the process from step S114 onwards in Fig. 2. In this case, as shown in Fig. 2, the temperature and speed detection process of step S116 is not executed, and the process proceeds to the microwave oven tilt detection process of step S121.
[0066] If the auto-cruise mode is OFF (S301: NO), the control unit 40 turns OFF the second detection flag for the auto-cruise detection process (S303), and returns to the process from step S114 onwards in Fig. 2. In this case, as shown in Fig. 2, the temperature and speed detection process of step S116 is executed.
[0067] <Temperature and speed detection processing> 5 is a flowchart showing an example of the temperature and speed detection process according to Embodiment 1. Next, the process of step S116 will be described in detail with reference to FIG.
[0068] Control unit 40 acquires a measurement value from temperature sensor 34 installed in microwave oven 30, and determines whether the temperature of the heating object inside the oven is equal to or higher than a predetermined threshold value (for example, 70° C.) (S401).
[0069] If the temperature of the object to be heated inside the storage compartment is equal to or higher than a predetermined threshold (S401: YES), the control unit 40 acquires vehicle information and determines whether the traveling speed is equal to or higher than a predetermined threshold (e.g., 60 km / h) based on information indicating the speed of the vehicle 1 contained in the vehicle information (S402).
[0070] If the traveling speed of the vehicle 1 is equal to or greater than the predetermined threshold (S402: YES), the control unit 40 turns on the fourth detection flag for the temperature and speed detection process (S403), and proceeds to the process of step S116 and subsequent steps in FIG.
[0071] If the temperature of the object to be heated inside the cabinet is below a predetermined threshold (S401: NO), or if the traveling speed of the vehicle 1 is below a predetermined threshold (S402: NO), the control unit 40 turns OFF the fourth detection flag for the temperature and speed detection process (S404), and proceeds to the process from step S116 onwards in Figure 2.
[0072] That is, when vehicle 1 is traveling at a high speed and the temperature of the object to be heated inside the microwave oven is high, control unit 40 turns on the fourth detection flag. In this case, door 32 of microwave oven 30 is locked in step S151 of FIG. 2. This prevents door 32 of microwave oven 30 from opening while vehicle 1 is traveling at a high speed, and prevents the high-temperature object from flying out of the microwave oven.
[0073] Note that microwave oven 30 may implement only the temperature and speed detection process (S116), and not implement the sudden stop detection process (S112), the auto-cruise detection process (S114), and the microwave oven tilt detection process (S121). In this case, control unit 40 may control door lock unit 33 to unlock door 32 instead of turning the fourth detection flag OFF in step S403, and may control door lock unit 33 to lock door 32 instead of turning the fourth detection flag ON in step S404.
[0074] Furthermore, the control unit 40 may perform the temperature and speed detection process even after the heating is completed in step S153. In this case, even after the heating is completed, the door 32 remains locked until the temperature of the heated object falls below a predetermined threshold or the traveling speed of the vehicle 1 falls below a predetermined threshold. This prevents the user (passenger) from opening the door 32 and touching the high-temperature heated object while the vehicle 1 is traveling at high speed.
[0075] <Microwave oven tilt detection processing> 6 is a flowchart showing an example of the microwave oven tilt detection process according to Embodiment 1. Next, the process of step S121 will be described in detail with reference to FIG.
[0076] Control unit 40 acquires a measurement value of acceleration sensor 35 installed in microwave oven 30, and determines whether or not the inclination of microwave oven 30 is equal to or greater than a predetermined threshold (for example, a road gradient of 10% or greater) (S501).
[0077] If the tilt of microwave oven 30 is less than the predetermined threshold (S501: NO), control unit 40 determines whether the amount of change in the measurement value of the acceleration sensor over a predetermined period of time (for example, several tens to several hundreds of milliseconds) is equal to or greater than a predetermined threshold (S502). In other words, control unit 40 determines whether microwave oven 30 has experienced a large vibration.
[0078] If the change in the measurement value of acceleration sensor 35 over a predetermined time period is less than a predetermined threshold (S502: NO), control unit 40 turns OFF the third detection flag for the microwave oven tilt detection process (S503), and proceeds to the process from step S121 onwards in Figure 2.
[0079] If the tilt of microwave oven 30 is equal to or greater than a predetermined threshold (S501: YES), or if the change in the measurement value of acceleration sensor 35 over a predetermined period of time is equal to or greater than a predetermined threshold (S502: YES), control unit 40 turns ON the third detection flag for the microwave oven tilt detection process (S504), and proceeds to the process from step S121 onwards in Figure 2.
[0080] That is, when microwave oven 30 is tilted significantly or when microwave oven 30 experiences large vibrations, control unit 40 turns on the third detection flag. In this case, door 32 of microwave oven 30 is locked in step S151 of FIG. 2. This prevents microwave oven 30 from tilting, opening door 32, and causing the object to be heated to fly out of the oven. It also prevents microwave oven 30 from experiencing large vibrations, opening door 32, and causing the object to be heated to fly out of the oven.
[0081] Note that microwave oven 30 may implement only the microwave oven tilt detection process (S121), and not implement the sudden stop detection process (S112), the auto-cruise detection process (S114), and the temperature and speed detection process (S111). In this case, control unit 40 may control door lock unit 33 to unlock door 32 instead of turning the third detection flag OFF in step S503, and may control door lock unit 33 to lock door 32 instead of turning the third detection flag ON in step S504.
[0082] <To unlock the microwave door> As shown in step S152 of FIG. 2, when the driving state of vehicle 1 is relatively safe even if door 32 of microwave oven 30 can be opened, control unit 40 unlocks door 32 of microwave oven 30.
[0083] For example, in the process shown in FIG. 2, even if the vehicle 1 is traveling, if no sudden stop is detected (the first detection flag is OFF), the auto-cruise mode is ON (the second detection flag is ON), and no tilt or the like of the microwave oven 30 is detected (the third detection flag is OFF), the control unit 40 controls the door lock unit 33 to unlock the door 32 of the microwave oven 30.
[0084] Alternatively, even if the vehicle 1 is traveling, the control unit 40 controls the door lock unit 33 to unlock the door 32 of the microwave oven 30 if no sudden stop is detected (the first detection flag is OFF), the auto-cruise mode is OFF (the second detection flag is OFF), the temperature of the object to be heated is not very high or the traveling speed is not very fast (the fourth detection flag is OFF), and no tilt or the like of the microwave oven 30 is detected (the third detection flag is OFF).
[0085] This allows the user (passenger) to open door 32 of microwave oven 30 when it is relatively safe even while vehicle 1 is traveling, improving convenience.
[0086] The reason why the temperature and speed detection process (S116) is omitted when the auto-cruise mode is ON is as follows: In the auto-cruise mode, the driver does not operate the accelerator, so even if the conditions for unlocking door 32 of microwave oven 30 are relaxed, the impact on the driver (for example, the possibility of a driving error) is small.
[0087] (Summary of the first embodiment) The above description of the first embodiment discloses the following techniques.
[0088] <Technology 1> A microwave oven (30) mounted on a vehicle (1) includes an openable / closable door (32), a door lock unit (33) that locks or unlocks the door, a communication unit (39) that receives vehicle information related to the vehicle, and a control unit (40) that controls the door lock unit and locks or unlocks the door based on the vehicle information. This allows the door to be locked and unlocked depending on the vehicle's situation, improving the safety of the microwave oven.
[0089] <Technology 2> In the microwave oven described in Technology 1, the vehicle information includes information indicating the state of the brake lights of the vehicle and information indicating the speed of the vehicle, and the control unit controls the door lock unit to lock the door when the speed of the vehicle is equal to or greater than a predetermined threshold and the brake lights of the vehicle are on. As a result, if the vehicle 1 brakes suddenly, the door is locked, so that it is possible to prevent the door from opening and the object to be heated from flying out of the interior of the refrigerator.
[0090] <Technology 3> The microwave oven according to Technology 1 or 2 further includes a temperature sensor (34) that measures the temperature of an object to be heated inside the microwave oven, and the vehicle information includes information indicating the speed of the vehicle. When the temperature of the object to be heated measured by the temperature sensor is equal to or higher than a predetermined threshold and when the speed of the vehicle is equal to or higher than a predetermined threshold, the control unit controls the door lock unit to lock the door. As a result, if the object to be heated is at a high temperature and the vehicle is traveling at high speed, the door is locked, which prevents the door from opening and the object to be heated (for example, at a high temperature) from flying out from the interior of the compartment.
[0091] <Technology 4> The microwave oven according to any one of Techniques 1 to 3 further includes an acceleration sensor (35) that measures acceleration, and the control unit controls the door lock unit to lock the door when the tilt of the microwave oven obtained based on the measurement value by the acceleration sensor is equal to or greater than a predetermined threshold, or when the amount of change in the measurement value by the acceleration sensor over a predetermined period of time is equal to or greater than a predetermined threshold. This locks the door when the microwave oven is tilted significantly or when the microwave oven is subjected to significant vibration, thereby preventing the door from opening and the object to be heated from flying out of the oven.
[0092] <Technology 5> The microwave oven according to any one of techniques 1 to 4 further includes a temperature sensor (34) that measures the temperature of an object to be heated inside the microwave oven, wherein the vehicle information includes information indicating an auto-cruise state of the vehicle, and wherein, when the auto-cruise is off, if the temperature of the object to be heated measured by the temperature sensor is equal to or higher than a predetermined threshold and if the speed of the vehicle is equal to or higher than a predetermined threshold, the control unit controls the door lock unit to lock the door. This means that when auto-cruise is off, i.e., when the driver is driving, if the object to be heated is hot, and the vehicle is traveling at high speed, the door is locked, preventing the door from opening and the (e.g., hot) object to be heated from flying out of the compartment.
[0093] <Technology 6> The microwave oven according to claim 1 further comprises an acceleration sensor for measuring acceleration. The vehicle information includes information indicating the state of the brake lights of the vehicle, information indicating the speed of the vehicle, and information indicating the state of the auto-cruise of the vehicle, and the control unit turns off a first flag (e.g., a first detection flag) if the speed of the vehicle is less than a predetermined threshold or if the brake lights of the vehicle are not on, turns on a second flag (e.g., a second detection flag) if the auto-cruise is on, turns off a third flag (e.g., a third detection flag) if the tilt of the microwave oven obtained based on the measurement value by the acceleration sensor is less than a predetermined threshold and the amount of change in the measurement value by the acceleration sensor over a predetermined time period is less than a predetermined threshold, and controls the door lock unit to unlock the door if the first flag is off, the second flag is on, and the third flag is off. This improves the convenience of using the microwave oven while the vehicle is moving, as the door will be unlocked if the vehicle is not braking suddenly, auto-cruise is on, and the microwave oven is not tilted or vibrating significantly.
[0094] <Technology 7> The microwave oven described in Technology 6 further includes a temperature sensor that measures the temperature of an object to be heated inside the oven, and the control unit turns off the second flag when the auto-cruise is off, turns off a fourth flag (e.g., a fourth detection flag) when the temperature of the object to be heated measured by the temperature sensor is below a predetermined threshold or the speed of the vehicle is below a predetermined threshold, and controls the door lock unit to unlock the door when the first flag is off, the second flag is off, the fourth flag is off, and the third flag is off. This allows the door to be unlocked if the vehicle is not braking suddenly, the auto-cruise is off, the object to be heated is not hot, the vehicle is not traveling at high speed, and the microwave oven is not tilted or vibrating significantly, thereby improving the convenience of the microwave oven when the vehicle is traveling.
[0095] <Technology 8> In the microwave oven described in Technology 7, the control unit turns on the first flag when the speed of the vehicle is equal to or greater than a predetermined threshold and the brake lights of the vehicle are on, turns on the fourth flag when the temperature of the object to be heated is equal to or greater than a predetermined threshold and the speed of the vehicle is equal to or greater than a predetermined threshold, turns on the fourth flag when the tilt of the microwave oven is equal to or greater than a predetermined threshold or when the amount of change in the measurement value measured by the acceleration sensor over a predetermined period of time is equal to or greater than a predetermined threshold, and controls the door lock unit to lock the door when the first flag is on, the fourth flag is on, or the third flag is on. This allows the door to be locked when the vehicle brakes suddenly, when the object to be heated is hot, when the vehicle is traveling at high speed, or when the microwave oven is tilted or vibrated significantly, thereby improving the safety of the microwave oven when the vehicle is traveling.
[0096] <Technology 9> In the microwave oven described in any one of Techniques 1 to 7, the vehicle information includes information indicating the state of a shift lever, and the control unit does not start heating the object to be heated if the object to be heated inside the oven contains liquid or if the shift lever is not in park. This prevents the microwave oven from starting to heat the heating object including the liquid when there is a possibility that the vehicle is moving, thereby improving the safety of the microwave oven when the vehicle is moving.
[0097] <Technology 10> In the microwave oven described in Technical 9, the control unit stops the operation of the magnetron when the shift lever is no longer in the parking position while the magnetron is operating. This allows the microwave oven to stop heating the heating object including the liquid when there is a possibility that the vehicle is moving, thereby improving the safety of the microwave oven when the vehicle is moving.
