Description

The present invention relates to a heating cooker, a heating cooking system, and a display control method for a heating cooker.

A heating cooker is a device that heats and cooks an object by placing it in a heating chamber, and is equipped with a door that can be opened and closed at the front of the main body housing in order to store the object to be heated in the main body. The door is provided with a viewing window for checking the state of the food to be cooked in the heating chamber, and an operating section with a liquid crystal display is provided on the front of the main body or on the door.

However, in the cooking devices described in Patent Document 1 and Patent Document 3, it is difficult to intuitively understand the positional relationship between the food placed in the heating chamber and the image displayed on the liquid crystal display section. Especially when multiple foods are placed in the heating chamber, the determination becomes difficult. Further, since the measurement results are obtained from a direction different from the user's viewpoint, the relationship between the temperature distribution information and the placement position becomes even more difficult to understand.

Further, the heating cooker described in Patent Document 2 displays a visible light image and can notify which food is in which place, but cannot notify the user of food temperature information. Furthermore, the viewing window provided in the door becomes smaller, resulting in poor visibility of the heating chamber.

Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the respective figures.
FIG. 1 is a configuration diagram of a heating cooker 5 of this embodiment.
The heating cooker 5 includes a control means 51, a magnetron 52, a motor 53, an antenna 54, a touch panel display 55, a thermoviewer 56, a storage section 57, and a heating chamber 58. A program 571 is stored in the storage unit 57.

The heating chamber 58 is a part that accommodates and heats food.
The control means 51 is, for example, a combination of a CPU (Central Processing Unit) and a RAM (Random Access Memory), and receives an input signal from a touch panel display 55, an input signal from a start switch (not shown), a detection signal from a thermoviewer 56, etc. be done. By executing a program 571, the control means 51 controls the magnetron 52, controls the angle of the antenna 54 by the motor 53, controls the touch panel display 55, etc. based on the input signal and the detection signal.

The magnetron 52 supplies microwaves to the inside of the heating chamber 58 via an antenna 54. The motor 53 rotates a rotatably provided antenna 54 to a desired angle. The touch panel display 55 has a transparent touch panel superimposed on the display, and functions as an operation display unit that receives operation input and displays the current process.

As shown in FIG. 2, which will be described later, a thermoviewer 56 for detecting the temperature distribution of the heating chamber is provided at the upper end of the heating chamber 58 on the back side. This thermoviewer 56 can simultaneously detect the temperature of a predetermined area on which the object to be heated is placed, and in this embodiment, the temperature of four areas is simultaneously detected separately. The storage unit 57 is configured of, for example, a flash memory or a ROM (Read Only Memory), and stores a program 571.

FIG. 2 is a perspective view of a cut model of the cooking device 5. As shown in FIG.
A thermoviewer 56 that detects the surface temperature of the object to be heated is provided at the upper end of the heating chamber 58 on the back side. This thermoviewer 56 simultaneously detects the temperature of the area 581 where the object to be heated is placed. The control means 51 generates an infrared image 4 of the food as shown in FIG. 3 based on the detection information of the thermoviewer 56. Note that the visible light image 3 in FIG. 4 is a reference image when the food in the infrared image 4 in FIG. 3 is photographed using visible light.

The heating chamber 58 is a space surrounded by a housing 501 and a door 502, and stores food and heats the food.

In cooking appliances, a non-contact temperature measuring device such as a thermoviewer is most commonly installed at the upper part of the inside wall of the refrigerator. As a result, the design advantage is that the distance to the center of the refrigerator can be increased, and most of the bottom surface of the heating chamber can be detected. On the other hand, when measuring from the upper part of the side wall, there is a problem in that if a tall food or container is placed on the measuring device side, the area ahead becomes a blind spot. In this embodiment, the thermoviewer 56 is installed at the rear of the upper surface inside the cooking device 5 to solve the problem of setting most of the bottom surface of the heating chamber as a detection range from above.

As shown in FIG. 2, when the thermoviewer 56 is installed at the rear of the upper surface of the refrigerator, the measurement range at the rear of the refrigerator, which is close to the thermoviewer 56, is narrow, and the measurement range at the front of the refrigerator is wide. Moreover, the color map showing the temperature distribution becomes an infrared image 4 as shown in FIG. 3, and it is difficult to understand the positional relationship even if it is displayed as is.

Therefore, in the present invention, an image including the side and back surfaces of the heating chamber 58 and imagining the heating chamber 58 and a temperature distribution image converted into a perspective image according to this image are combined and displayed on the touch panel display 55. The temperature distribution image displayed superimposed on the image illustrating the heating chamber 58 is a perspective image. This makes it easier to understand the relationship between food and its temperature.

FIG. 5 is a mode transition diagram of the cooking device 5. As shown in FIG.
When the heating cooker 5 starts operating, it transitions to an initial state 10. In the initial state 10, the initial setting screen 20 of FIG. 7 is displayed on the touch panel display 55 of the cooking device 5. In the initial state 10, when the control means 51 detects that a start button (not shown) is pressed, the process transitions to an initial measurement step 11.

The initial measurement step 11 is a step in which the control means 51 measures the weight, center of gravity, temperature distribution, etc. of the food to determine the food area. In the initial measurement step 11, the initial measurement screen 21 of FIG. 8 is displayed on the touch panel display 55 of the cooking device 5. When the control means 51 determines the food area by measuring the weight, center of gravity, temperature distribution, etc. of the food, the control means 51 shifts to the search step 13.

The search step 13 is a step of searching for the optimal angle of the antenna 54. In the search step 13, the search screen 23 of FIG. 10 is displayed on the touch panel display 55 of the cooking device 5. In the search step 13, when the control means 51 detects the optimum angle of the antenna 54 and succeeds in the search, the process shifts to the control step 15. In the initial measurement step 11 and the search step 13, when the change tab is tapped (operation input), the process transitions to the overall target temperature change step 12.
In the overall target temperature changing step 12, the overall target temperature changing screen 22 of FIG. 9 is displayed on the touch panel display 55 of the cooking device 5. In the overall target temperature changing step 12, when the decision button is pressed, the process returns to the original step.

In the search step 13, when any region of the temperature distribution image 212 displayed on the search screen 23 in FIG. 10 is pressed, the process transitions to the individual target temperature change step 14.
In the individual target temperature changing step 14, the individual target temperature changing screen 24 of FIG. 11 is displayed on the touch panel display 55 of the cooking device 5. When the determination button is pressed in the individual target temperature change step 14, the process returns to the original search step 13.

Control step 15 is a step of heating food. In the control step 15, the control screen 25 of FIG. 12 is displayed on the touch panel display 55 of the cooking device 5. In the control step 15, when the food reaches the target temperature, the control means 51 transitions to the heating success state 16 and ends the mode transition of FIG. 3. In the heating success state 16, the heating success screen 26 of FIG. 13 is displayed on the touch panel display 55 of the heating cooker 5.

In the control step 15, if the temperature difference between each region of the food exceeds the threshold value, the control means 51 shifts to the temperature difference reduction step 17.
In the temperature difference reducing step 17, the temperature difference reducing screen 27 of FIG. 14 is displayed on the touch panel display 55 of the cooking device 5. In the temperature difference reduction step 17, the control means 51 determines whether the reduction of the temperature difference has failed or succeeded while heating relatively low temperature areas of the food more strongly than high temperature areas. . If the control means 51 succeeds in reducing the temperature difference, it returns to the control step 15. If the control means 51 fails to reduce the temperature difference, it transits to the heating failure state 18 and ends the mode transition of FIG. 3. In the heating failure state 18, the heating failure screen 28 of FIG. 15 is displayed on the touch panel display 55 of the cooking device 5.

6A and 6B are flowcharts of the heat treatment.
By pressing the start button, a series of heat treatments shown in FIGS. 6A and 6B start.
First, the control means 51 estimates the amount of food using a weight sensor (not shown) (step S10). The process in step S10 corresponds to the initial measurement step 11 in FIG.
Then, the control means 51 starts sensing by the thermoviewer 56 (step S11). The control means 51 determines the food area, labels the maximum temperature (step S12), and starts displaying the maximum temperature for each food area (step S13).

The control means 51 starts microwave heating (step S14) and executes control to search for an optimal antenna angle (step S15). The processing from steps S11 to S15 corresponds to the search step 13 in FIG.
After that, the control means 51 measures the temperature increase rate (step S16), calculates the remaining time from the temperature increase rate (step S17), and displays the remaining time (step S18).

In step S19, the control means 51 determines whether the temperature difference between regions is greater than or equal to a threshold value. If the temperature difference between regions is less than the threshold value (No), the control means 51 proceeds to step S20, and if the temperature difference between regions is equal to or greater than the threshold value (Yes), the control means 51 proceeds to step S21.

In step S20, the control means 51 determines whether the target temperature has been reached. If the target temperature has not been reached (No), the control means 51 returns to step S16. If the target temperature is reached (Yes), the control means 51 displays a message to the effect that heating has been successful (step S24), and ends the process of FIG. 6B. The repeated processing from steps S16 to S20 corresponds to control step 15 in FIG.

In step S21, the control means 51 heats so as to reduce the temperature difference. Then, the control means 51 displays that the low temperature region is being intensively heated (step S22), and determines whether or not the reduction of the temperature difference has failed (step S23).
If the control means 51 has not failed in reducing the temperature difference (No), it returns to the process of step S16. If the control means 51 fails to reduce the temperature difference (Yes), it displays the fact that the heating has failed (step S25), and ends the process of FIG. 6B. The processing from steps S16 to S23 corresponds to the temperature difference reduction step 17 in FIG.
