Embodiment 1.
The cooking cooker according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 6.

In FIG. 1, the heating cooker main body 1 has a heating chamber 2 in which a food object or an object to be heated 3 including a container on which food is placed is housed, and a top surface heating heater 5 provided behind the ceiling surface of the heating chamber 2. The object to be heated 3 stored in the heating chamber 2 is heated by the upper surface heating heater 5. Further, the cooking machine main body 1 includes a door 4 provided so that the heating chamber 2 can be opened and closed in the vertical direction, a convection heater 6 provided on the back surface of the heating chamber 2, and an operation display panel 7.

The portion to be cleaned is a portion that can be cleaned by the user, for example, a side wall surface, a ceiling surface, or a bottom surface in the heating chamber 2. In the present embodiment, the ceiling surface of the heating chamber 2 corresponds to the part to be cleaned.

The top surface heating heater 5 corresponds to the heating means in the present invention. The top surface heating heater 5 is formed by a so-called flat heater in which a nichrome wire is wound around a mica plate and is in close contact with an iron plate, whereby the inside of the heating chamber 2 can be uniformly heated and the cleaning property is also good. There is.

The convection heater 6 is composed of a convection fan 6a and a blower air heating heater 6b attached in the vicinity of the convection fan 6a and composed of a glass tube heater. The convection heater 6 sucks and heats the air in the heating chamber 2 and discharges the heated air into the heating chamber 2 to heat the object to be heated 3 stored in the heating chamber 2.

The operation display panel 7 has a power on / off switch, a cancel button, an automatic menu selection button, a temperature or heating mode selection switch, a temperature in the heating chamber 2 during cooking, selected heating settings, a menu, and the like. It has a display unit that allows the high temperature caution display after cooking to be visually recognized. The user can operate the cooking cooker on the operation display panel 7.

As shown in FIG. 2, the heating cooker main body 1 includes an infrared sensor 8 provided on a side wall in the heating chamber 2 and a motor 9 for rotating the infrared sensor 8 up and down. The infrared sensor 8 corresponds to the temperature measuring means in the present invention. As the infrared sensor 8, an infrared detecting means which is a non-contact type temperature detecting means, for example, a thermopile type infrared sensor or the like is used. Reference numeral 8a in FIG. 2 indicates a detection field of view which is a region where the infrared sensor 8 can receive infrared rays when heating is performed by the upper surface heating heater 5. The infrared sensor 8 faces the direction in which the object to be heated 3 is housed, and detects the amount of infrared rays in the detection field of view 8a.

Reference numeral 8b in FIG. 3 indicates a detection field of view which is a region where the infrared sensor 8 can receive infrared rays after the heating by the upper surface heating heater 5 is stopped. The infrared sensor 8 has a top heating heater 5 facing the ceiling surface of the heating chamber 2 provided on the back surface, and detects the amount of infrared rays in the detection field of view 8b.

The amount of infrared rays detected by the infrared sensor 8 is converted into temperature by the control unit 10 described later, and is used to estimate the temperature of the object to be detected. The infrared sensor 8 has a built-in element that detects the ambient temperature in addition to the element that receives infrared rays, and can correct an increase in the amount of infrared rays due to the atmospheric temperature and a difference in the temperature of the object to be detected. There is.

In order to stabilize the temperature of the infrared sensor 8 itself, it is preferable to sufficiently cool the infrared sensor 8 with a cooling fan (not shown) even when the inside of the heating chamber 2 is heated. By causing the infrared sensor 8 to detect the temperature of the object to be heated 3 while cooling the infrared sensor 8, the output fluctuation of the element that detects the ambient temperature of the infrared sensor 8 is reduced, and the deterioration of the temperature detection accuracy is suppressed. be able to.

As shown in FIG. 4, the cooking cooker main body 1 includes a control unit 10 and a sound source device 11 inside. The control unit 10 controls the top surface heating heater 5, the convection fan 6a, the blown air heating heater 6b, and the sound source device 11 based on the information from the operation display panel 7 and the infrared sensor 8.

The sound source device 11 corresponds to the notification means in the present invention. The sound source device 11 is controlled by the control unit 10 to generate sound or voice.

Next, the operation of notifying the cleaning timing in the cooking cooker configured in this way will be described with reference to FIG.

(S1)
First, the user opens the door 4 to cook the object to be heated 3, stores the object to be heated 3 in the heating chamber 2, closes the door 4, selects a menu on the operation display panel 7, and starts. Press the button to start cooking. Then, the process proceeds to step S2.

(S2)
The control unit 10 causes the infrared sensor 8 to detect the temperature T_food of the object to be heated 3. Then, the process proceeds to step S3.

(S3)
The control unit 10 determines the timing at which the cooking is finished in consideration of the time for the change in T_food or the change in T_food detected by the infrared sensor 8. As a result of the determination, if the condition for ending the cooking is reached, the process proceeds to step S4. On the other hand, if the condition for ending the cooking is not reached, the process returns to step S2 and the cooking is continued.

(S4)
The control unit 10 changes the infrared sensor 8 upward, that is, the direction in which the upper surface heating heater 5 looks at the ceiling surface in the heating chamber 2 mounted on the back surface. Then, the process proceeds to step S5.

(S5)
The control unit 10 causes the infrared sensor 8 to detect the ceiling surface temperature T_ceiling in the heating chamber 2. Then, the process proceeds to step S6.

(S6)
The control unit 10 determines whether or not the T_ceiling detected by the infrared sensor 8 has reached the first temperature T_1 stored in advance. As a result of the determination, if T_ceiling has reached the first temperature T_1, the process proceeds to step S7. On the other hand, if T_ceiling has not reached the first temperature T_1, the process returns to step S5 and the detection of T_ceiling is continued. At this time, the first temperature T_1 is set within a temperature range in which there is a low risk of burns even if a person touches it for cleaning. At 70 ° C. or higher, burns occur in 1 second, and since it is 60 ° C. or higher that the heat stimulates a person's pain sensation, the temperature is set lower than that. For example, it is in the range of 50 ° C to 55 ° C.

(S7)
The control unit 10 causes the sound source device 11 to execute the first notification consisting of one beep sound. Then, the process proceeds to step S8.

(S8)
The control unit 10 determines whether or not the cancel button on the operation display panel 7 has been pressed. When the pressing of the cancel button is detected, it is considered that the user intends to start cleaning, and the process proceeds to step S11. On the other hand, if the pressing of the cancel button is not detected, the process proceeds to step S9.

(S9)
The control unit 10 determines whether or not the T_ceiling detected by the infrared sensor 8 has reached the second temperature T_2 stored in advance. As a result of the determination, if T_ceiling has reached the second temperature T_2, the process proceeds to step S10. On the other hand, if T_ceiling has not reached the second temperature T_2, the process returns to step S8, and it is determined that the cancel button is pressed. At this time, the second temperature T_2 is set within a temperature range in which dirt can be easily removed. It is known that oil and fat stains are easy to remove because they form a liquid crystal with a surfactant under a temperature condition of 40 ° C. or higher. Based on this, the second temperature T_2 is, for example, a temperature of 40 ° C. or higher at which oil and fat stains are less likely to become liquid crystal and solidification starts, and is in the range of 40 ° C. to 45 ° C.

(S10)
The control unit 10 causes the sound source device 11 to execute a second notification different from the first notification, for example, a notification consisting of a beep sound longer than the first notification. Then, the process proceeds to step S11.

(S11)
Since it is not necessary to detect T_ceiling by the infrared sensor 8 after the second notification is completed, that is, after all the notifications are completed, the control unit 10 faces the infrared sensor 8 downward, that is, the object to be heated 3 is housed. Return to the direction.

Next, the control timing in the cooking cooker configured as described above will be described with reference to FIG. In step S1, the control unit 10 operates the top surface heating heater 5, the convection fan 6a, and the blown air heating heater 6b to start cooking the object 3 to be heated. At this time, the infrared sensor 8 faces downward, that is, toward the object to be heated 3. In step S4, the control unit 10 stops the upper surface heating heater 5 and the blown air heating heater 6b to end the cooking. At this time, the operating state of the convection fan 6a is maintained in order to promote cooling in the heating chamber 2. In step S7, the control unit 10 stops the operation of the convection fan 6a to stop the cooling in the heating chamber 2.

As described above, according to the first embodiment, when the temperature detected by the infrared sensor 8 reaches the first temperature T_1, which has a low risk of burns even if touched, the first notification is performed by the notification means. Will be. When the dirt reaches the second temperature T_2, which is still warm and easy to remove, the notification means gives a second notification, which reduces the risk of burns to the user and cleans the dirt in a state where it is easy to remove. It produces the effect that can be done.

Further, in the above-described first embodiment, the temperature of the part to be cleaned is set to the ceiling surface temperature which is the highest temperature in the heating chamber 2, and the execution of notification is determined based on the temperature, so that the user is burned during cleaning. The risk can be effectively reduced.

Further, in the above-described first embodiment, since the infrared sensor 8 is rotatably provided, it is not necessary to provide a plurality of temperature sensors for each object for detecting the temperature, and there is an effect that the cost is low.

Further, in the first embodiment described above, the operation of the convection fan 6a is stopped when the temperature of the part to be cleaned reaches the first temperature, so that the temperature of the part to be cleaned may drop sharply thereafter. There is also an effect that sufficient cleaning time can be secured.

Further, in the first embodiment described above, since it is determined whether or not the second notification needs to be performed based on the pressing of the cancel button on the operation display panel 7, the user starts cleaning with the first notification as a trigger. In some cases, there is also an effect of reducing the feeling of annoyance due to the second notification being performed during cleaning.

In the first embodiment described above, an example in which the top surface heating heater 5 is formed of a flat heater has been described, but a glass tube heater may be used. When a glass tube heater is used, the radiant component at the time of heating is increased to increase the heating rate on the surface of the object to be heated 3, and the surface of the meat is baked and hardened so that the deliciousness contained in the gravy can be cooked without escaping. Moreover, you may use a sheathed heater as a cheaper heating means.

Further, in the first embodiment described above, an example in which the first notification by the sound source device 11 is a beep sound once and the second notification is a beep sound longer than the first notification has been described. The length and frequency of the beep sound to be notified for the notification and the second notification are not limited. Further, the beep sound may be composed of a plurality of short sounds. The notification by the sound source device 11 may be voice, and the first notification and the second notification may be different. For example, the first notification may consist of a voice saying "the temperature has reached the point where cleaning can be started", and the second notification may consist of a voice saying "It is easy to remove dirt, please clean it".

Further, in the above-described first embodiment, the example in which the sound source device 11 is used as the notification means has been described, but light or a display may be used. Further, the mobile terminal may be notified. By using the portable terminal as the notification means, the user can recognize that the cooking cooker is in a state suitable for cleaning even if the cooking cooker is away from the cooking cooker.

Further, in the first embodiment described above, an example in which the temperature of the portion to be cleaned is set to the ceiling surface temperature which is the highest temperature in the heating chamber 2 has been described, but the bottom surface temperature which is the lowest temperature may be used. At this time, the control unit 10 causes the infrared sensor 8 to detect the bottom surface temperature in the heating chamber 2, and determines the execution of notification based on the temperature. Therefore, the user can clean the temperature of all the parts in the heating chamber 2 while the oil stains are still soft and easy to remove.

Further, the operation display panel 7 may be provided with a setting unit in which a portion desired to be cleaned by the user, that is, a portion to be cleaned can be set, and the execution of notification may be determined based on the temperature of the set portion. For example, when the user wants to clean the bottom surface in the heating chamber 2, it is assumed that the "bottom surface" is set as the part to be cleaned in the setting unit. At this time, the control unit 10 causes the infrared sensor 8 to detect the bottom surface temperature in the heating chamber 2, and determines the execution of notification based on the temperature. As a result, notification is sent when the temperature of the part desired by the user reaches a temperature suitable for cleaning, so that the risk of burns to the user is reduced and the desired part can be easily removed. Can be cleaned.

In the first embodiment described above, an example in which the first temperature is in the range of 50 ° C. to 55 ° C. and the second temperature is in the range of 40 ° C. to 45 ° C. has been described. It may be within a temperature range where there is a low risk of burns even if it is touched for cleaning. Further, the second temperature may be 40 ° C. or higher at which oil and fat stains can be easily removed, and may be in a temperature range lower than the first temperature.

Embodiment 2.
The cooking cooker according to the second embodiment of the present invention will be described with reference to FIGS. 7 to 9. In the figure, the same reference numerals as those in FIGS. 4, 5 and 6 indicate the same or corresponding parts.

The heating cooker of the first embodiment uses a sound source device 11 as a notification means, and performs a second notification when the infrared sensor 8 detects a second temperature. On the other hand, the heating cooker of the second embodiment uses the light source device 12 as a notification means, and the third temperature is lower than the second temperature since the infrared sensor 8 detects the second temperature. The second notification is continuously performed during the period until the temperature is detected.

In addition, continuation is to continue what has been done from before. On the other hand, continuity is a continuous continuation, and continuity is a concept that includes continuation. Therefore, the second notification in the heating cooker of the second embodiment repeats the same operation during the notification period.

Since the cleaning timing notification operation of the second embodiment is the same as that of the first embodiment up to step S9, it will be described with reference to FIGS. 8 from step S10a onward.

(S10a)
The control unit 10 causes the light source device 12 to start a second notification different from the first notification. For example, when the first notification in step S7 is such that the light source device 12 blinks the light twice, the second notification in step S10a is to turn on the light by the light source device 12. That is, in step S10a, the control unit 10 causes the light source device 12 to start a second notification for turning on the light. Then, the process proceeds to step S10b.

(S10b)
The control unit 10 determines whether or not the cancel button on the operation display panel 7 has been pressed. When the pressing of the cancel button is detected, it is considered that the user intends to start cleaning, and the process proceeds to step S11. On the other hand, if the pressing of the cancel button is not detected, the process proceeds to step S10c.

(S10c)
The control unit 10 determines whether or not the T_ceiling detected by the infrared sensor 8 has reached the third temperature T_3 stored in advance. As a result of the determination, if T_ceiling has reached the third temperature T_3, the process proceeds to step S10d. On the other hand, if T_ceiling has not reached the third temperature T_3, the process returns to step S10b to determine that the cancel button has been pressed. At this time, the third temperature T_3 is set at a temperature within a temperature range in which dirt can be easily removed and is lower than the second temperature T_2. For example, the temperature is 40 ° C., which makes it difficult for oil and fat stains to become liquid crystal and starts solidification.

(S10d)
The control unit 10 stops the second notification that has been continuously performed from step S10a. That is, by turning off the light that has been continuously lit, the user is made to recognize that the temperature of the part to be cleaned is out of the temperature range suitable for cleaning. Then, the process proceeds to step S11.

Next, since the control timing in the cooking cooker configured as described above is the same as that of the first embodiment up to step S9, it will be described from step S10a onward with reference to FIG. During the period from step S10a to step S10d, the light source device 12 keeps lighting the light. Other configurations are the same as those in the first embodiment.

Even in the heating cooker configured in this way, as in the cooking cooker shown in the first embodiment, there is a low risk of burns even if the temperature detected by the infrared sensor 8 is touched. When the temperature T_1 is reached, the first notification is performed by the notification means. When the dirt reaches the second temperature T_2, which is still warm and easy to remove, the notification means gives a second notification, which reduces the risk of burns to the user and cleans the dirt in a state where it is easy to remove. It produces the effect that can be done.

Further, in the heating cooker shown in the second embodiment, it is continuously notified that the temperature of the part to be cleaned is in a temperature range in which the risk of burns is low and dirt can be easily removed. There is also an effect that the user can effectively recognize the notification.

Further, in the first embodiment described above, since it is determined whether or not the second notification needs to be continued based on the pressing of the cancel button on the operation display panel 7, the user starts cleaning with the second notification as a trigger. In some cases, there is also an effect of reducing the feeling of annoyance due to the second notification being performed during cleaning.

Embodiment 3.
The cooking device according to the third embodiment of the present invention will be described with reference to FIG. In the figure, the same reference numerals as those in FIGS. 5 and 6 indicate the same or corresponding parts.

The heating cooker of the second embodiment continues the second notification by the light source device 12 as the notification means during the period from the time when the infrared sensor 8 detects the second temperature to the time when the third temperature is detected. And do it. On the other hand, in the heating cooker of the third embodiment, the second notification by the light source device 12 is intermittently performed.

As shown in FIG. 10, in the cooking cooker shown in the third embodiment, the second notification started in step S10a is intermittently operated during the period up to step S10d. That is, the light source device 12 keeps blinking the light during the period from step S10a to step S10d. Other configurations are the same as those in the second embodiment.

Even in the heating cooker configured in this way, as in the cooking cooker shown in the first embodiment, there is a low risk of burns even if the temperature detected by the infrared sensor 8 is touched. When the temperature T_1 is reached, the first notification is performed by the notification means. When the dirt reaches the second temperature T_2, which is still warm and easy to remove, the notification means gives a second notification, which reduces the risk of burns to the user and cleans the dirt in a state where it is easy to remove. It produces the effect that can be done.

Further, as in the case of the heating cooker shown in the second embodiment, it is continuously notified that the temperature of the part to be cleaned is in a temperature range in which the risk of burns is low and dirt can be easily removed, which is more effective. There is also an effect that the user can be made to recognize the notification.

Further, in the cooking cooker shown in the third embodiment, since the second notification is intermittently performed, the heating cooking shown in the second embodiment in which the second notification is continuously performed is performed. It also has the effect of saving more energy than a vessel.

In the above-described second and third embodiments, the example in which the light source device 12 is used as the notification means has been described, but the sound source device 11 or the display may be used. In particular, when the sound source device 11 is used, the notification can be recognized even if the user does not visually observe the cooking cooker, and the user can be more effectively alerted. Further, the mobile terminal may be notified. By using the portable terminal as the notification means, the user can recognize that the cooking cooker is in a state suitable for cleaning even if the cooking cooker is away from the cooking cooker.

Embodiment 4.

The heating cooker of the second embodiment uses the light source device 12 as the notification means, and serves as the notification means during the period from the time when the infrared sensor 8 detects the second temperature to the time when the third temperature is detected. The second notification is continuously performed by the light source device 12 of the above. On the other hand, the heating cooker of the fourth embodiment uses the display device 13 as the notification means, and the second notification by the display device 13 is changed according to the change in the temperature measured by the infrared sensor 8. It is something that makes you.

As shown in FIG. 12, in the cooking cooker shown in the fourth embodiment, the second notification performed during the period from step S10a to step S10d accompanies the change in temperature measured by the infrared sensor 8. Change. When the first notification in step S7 indicates on the display unit of the operation display panel 7 that cleaning can be started by the display device 13, the second notification in step S10a is For example, the temperature detected by the infrared sensor 8 or the information about the time estimated from the temperature until the end of the notification is continuously displayed by characters or figures.

FIG. 13 shows a display example in which the second notification in step S10a is to display the temperature information detected by the infrared sensor 8 using characters and figures. FIG. 13A is a display example when the temperature detected by the infrared sensor 8 is 45 ° C. FIG. 13B is a display example when the temperature detected by the infrared sensor 8 is 41 ° C. FIG. 13C is a display example when the temperature detected by the infrared sensor 8 is 40 ° C., that is, when the notification is terminated. In this way, the second notification is changed according to the temperature change of the cooking device. Other configurations are the same as those in the second embodiment.

Even in the heating cooker configured in this way, as in the cooking cooker shown in the first embodiment, there is a low risk of burns even if the temperature detected by the infrared sensor 8 is touched. When the temperature T_1 is reached, the first notification is performed by the notification means. When the dirt reaches the second temperature T_2, which is still warm and easy to remove, the notification means gives a second notification, which reduces the risk of burns to the user and cleans the dirt in a state where it is easy to remove. It produces the effect that can be done.

Further, as in the case of the heating cooker shown in the second embodiment, it is more effective because the temperature of the part to be cleaned is continuously notified that the risk of burns is low and the temperature range is easy to remove stains. There is also an effect that the user can be made to recognize the notification.

Further, in the cooking cooker shown in the fourth embodiment, since the second notification changes according to the temperature change of the cooking cooker, the user can recognize the temperature condition of the cooking cooker. it can. Further, at this time, by displaying the information on the estimated time from the temperature of the cooking device to the end of the notification, the user can recognize the time until the end of the temperature range suitable for cleaning, and the cleaning is started. It also has the effect of being able to adjust the timing of the operation.

Although the example in which the display device 13 is used as the notification means has been described in the above-described fourth embodiment, the sound source device 11 or the light source device 12 may be used. In particular, when the light source device 12 is used, the blinking interval of the light may be shortened as the temperature measured by the infrared sensor 8 decreases to call the user's attention. Further, the mobile terminal may be notified. By using the portable terminal as the notification means, the user can recognize that the cooking cooker is in a state suitable for cleaning even if the cooking cooker is away from the cooking cooker.

Further, the above-described first to fourth embodiments will be described as determining whether or not the subsequent notification needs to be performed based on the pressing of the cancel button on the operation display panel 7 after the notification is performed. However, when the door 4 is closed after cooking, it may be determined whether or not the subsequent notification needs to be performed based on the opening operation of the door 4. Since the user performs the operation of opening the door 4 when starting the cleaning, it is possible to reduce the trouble of pressing the cancel button on the operation display panel 7 before cleaning.

Further, if the pressing of the cancel button on the operation display panel 7 is detected before the first notification is performed, the subsequent notification control may be forcibly terminated. If the user feels annoyed to be notified, or if the user determines that cleaning is not necessary due to a low degree of contamination due to the previous cooking, the user's comfort can be ensured by forcibly terminating the notification control. ..

Further, with respect to the above-described first to fourth embodiments, an example in which one type of notification means is used and the first notification and the second notification are performed by the same notification means has been described, but a plurality of notification means are provided. , The first notification and the second notification may be performed by different notification means. For example, the first notification is a voice saying "the temperature has reached the level at which cleaning can be started" by the sound source device 11, and the second notification is a continuous notification of the temperature change of the heating cooker by the display device 13. There may be.

By the way, in the above-described first to fourth embodiments, the oven with a microwave oven function has been described as a cooking cooker, but an oven having a form of heating inside the box, for example, a grill may be used.
