Abstract

PURPOSE:To give stable finish to a food in cooking regardless of the time in which the food is left unattended as by the heater user's forgetting to turn over the grilled food by detecting time during which the food is left unattended after finishing grilling the back face of the food and multiplying a constant to this time to calculate the time required for additional grilling. CONSTITUTION:When the inside of a heating chamber reaches a detection temperature, P point, the time T1 which is required to reach it is set. A certain constant K1 is multiplied to this T1, and K1T1 is taken as the time required for finishing the grilling of the back side. At Q1 point, the time to finish the grilling of the back face a buzzer informs the time to turn over the food, and at the same time heating is stopped. Then the temperature of the heating chamber drops during the time TH in which the food is left unattended, and at R point, the time to start grilling the back face of the food after turning it over the food temperature has considerably dropped. According to the time TH an additional heating time K2TH is set. After the time K2TH has passed the heating chamber temperature at S point returns to a temperature corresponding to Q point, and after S point residual grilling for the surface of the food is made for a time that is determined by multiplying a constant K3 to the detection time T1 as the base which is set according to a food. With this method, regardless of whether the time of leaving food unattended, TH is long or short, a stable cooking performance is thereby given with a constant state of surface finish.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention Industrial Application Field The present invention relates to a heating device equipped with a temperature sensor, which has a heating control function for a heated object that requires turning over during cooking or heating. The present invention relates to a heating device equipped with a heating device.

2. Description of the Related Art In general, heating methods using a heating device equipped with a heater can be roughly divided into two types. One is oven cooking, in which sweets such as cakes and kutskii are baked, and the other is so-called grill cooking, in which baked fish, chicken thighs, etc. are browned.

Oven cooking is cooking in which the temperature inside the oven is raised so that the entire food is enveloped in hot air, and grilling is cooking in which food is quickly browned at high temperatures. For example, when cooking grilled fish, one side is grilled, then once it is properly browned, it is turned over and grilled on the other side.
Generally speaking, if the side on which food is to be served is the front side, the underside is grilled first, the front side is grilled later, and the side that looks freshly grilled and delicious is placed on the plate as the front side.

Conventionally, it has been difficult to automatically cook with heating devices that can perform grill cooking, so you have to manually set the time.
The drawback is that the user must always pay close attention to the cooking process, such as watching the cooking process on the other side and then flipping halfway through the process to cook the other side.

In addition, with a heating device that combines high-frequency heating and heater heating that can automatically cook grilled food, it first performs high-frequency heating, detects steam using a gas sensor or humidity sensor, and then heats the remaining heater. The method used was to calculate the time based on the time required to detect the time.

Problems to be Solved by the Invention However, with this control method, the heater heating time is determined at the moment of detection, and although the heating time for the surface is notified during heating, the baking time for the surface remains set and cannot be changed. Fine adjustment is not possible. In this case, for example, if the user forgets to turn it over due to some carelessness, the temperature in the heating chamber will drop rapidly, and even if he/she turns it over and sears the surface as soon as he/she notices it, it will not be browned enough and it will be half-cooked. It ends up being cooked.

Also, after the baking time for the back side ends, a notification sound will sound and the heating will stop, but there will be no notification after that.
There was a problem that once you missed it, you would not notice it at all and leave it unattended, resulting in no cooking.

The present invention solves these conventional problems, and even if the user forgets to turn the food over due to slight carelessness during grill cooking, it can be used regardless of the length of time the food is left unattended.
The present invention provides an excellent heating device that provides a stable finish.

Means for Solving the Problems The heating device of the present invention detects the length of time the back side is left unused after heating is completed when cooking is turned upside down during heating, and calculates the additional heating time by multiplying that time by a constant. It is configured to do so. Furthermore, in order to notify the user that the food is being left unattended, an alarm is sounded at regular intervals to call for attention, and the heating control is stopped after the maximum cooking time has elapsed.

Effect: The heating device of the present invention detects the time the back side is left unused after heating is completed, and multiplies the left time by a constant to set the additional heating time, thereby adjusting the additional heating time according to the length of the left time. will be set. In other words, the longer the heating chamber is left, the lower the temperature in the heating chamber will be, but the additional heating time will be longer, allowing the temperature in the heating chamber to return to the temperature at the end of heating the back surface. Therefore, the relationship between the temperature and time for baking the surface is approximately constant regardless of the time the food is left, and stable cooking can be achieved.

Additionally, an alarm sounds at regular intervals during the storage time to alert the user, ``Once the back side has finished baking, turn it over and cook the other side.'' This prevents overcooking or overheating due to residual heat. It works to

Furthermore, if the user does not notice the alarm sound and leaves it as it is, the heating control is stopped after a certain period of time to prevent overheating of the food and ensure safety.

EXAMPLE Hereinafter, a heating device according to an example of the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of a heating device according to the present invention.

A door body 2 is pivotally supported on the front surface of the main body 1 so as to be freely openable and closable, and an operation panel 3 is provided. A menu key 4 is arranged on this operation panel a.

FIG. 2 is a detailed view of the main parts of such an operation panel.

Menu key 4 lists various oven and grill dishes, and these are automatically cooked.

Among these dishes, the present invention is applied to dishes such as grilled fish and grilled chicken thighs, which are turned upside down during cooking.

FIG. 3 shows the temperature change over time in the heating chamber during baking of the menu. When heating starts, the temperature of the food increases as well as the temperature inside the heating chamber.

Then, when the inside of the heating chamber reaches the detected temperature point P, the time T1 required until then is set. T1 varies depending on the weight and initial temperature of the food, and as a matter of course, the heavier the food, the longer T1 becomes, and the lower the initial temperature, the longer T1 becomes, and T1 is set according to the condition of the food. Based on this detection time T1, a time Kl'r1 obtained by multiplying a certain constant by 1 is set as the baking time for the back side. If the end point of the baking time for the back side is the Q point, a buzzer etc. will be used to notify that the food has been turned over at the Q point.
At the same time, stop heating. By stopping heating, the heating chamber temperature decreases after the 0 point, that is, during the standing time TH.
At point R, when the food is turned over and the surface begins to bake, the temperature has dropped considerably. The time it takes to restore it is 2TH, and the time it takes to leave the room T) is the constant multiplied by 2.In a heating chamber with the door closed, the relationship between temperature and time is almost linear, and the leaving time T ) (2 TH is set for the additional heating time according to. At 8 points after K2TH has passed, Q
The heating chamber temperature returns to the point equivalent to that point, and after the 8th point, the rest of the surface is baked for a time that is a constant multiplied by 3 based on the detection time T1 set according to the food. Therefore, regardless of the length of the standing time T), the surface finish is almost constant and stable cooking performance can be obtained.

In addition, if you use a buzzer or display intermittently to notify you that the food has been turned over during the leaving time T'H, there is no need to monitor the cooking status near the heating device, and the time can be used effectively for other cooking or preparing the table. can. In addition, the remaining time KI T1 on the back side and 2 TH+ K3 'r1 on the remaining time on the front side are respectively set as points P and R.
It would be more convenient for the user if the values were displayed as points and gradually decreased.

Furthermore, even if the user goes out for urgent business while cooking, or is in a place where the alarm sound cannot be heard, and the user leaves the food unattended,
If heating control is stopped after a certain standing time, overheating after turning over can be prevented and it is safe.

Now, FIG. 4 shows the configuration of such a heating device.

Commands input from the menu key 4 on the operation panel s are terminated by the control section 5. Then, the control unit 5 starts supplying power to the heater, which is the heating means 7, via the driver 6. Inside the heating chamber 8, an object to be heated 9 is placed in a metal grate 10.
This drainboard net 10 functions to cut off oil, broth, etc. coming out of the object 9 to be heated. The temperature inside the heating chamber 8 is detected by a temperature sensor 12 disposed within the exhaust guide 11 at a predetermined temperature, and the signal is inputted to the control section 5 via the detection circuit 13. The control unit 5 is implemented by a microcomputer or the like.

With this configuration, the control shown in FIG. 3 can be performed and stable grill cooking can be performed.

Although an electric heater such as a sheathed heater is used as the heating means 7 in this embodiment, the same effect can be applied even if a heating means such as a sheet heating element or a gas burner is used.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) In grill cooking, even if the grill is left unattended after the back side has been grilled, stable cooking performance can be obtained regardless of the length of time the grill is left, and the grill can be grilled cleanly without failure.

(2) A temperature sensor detects the temperature of the heating chamber, so even if the weight and initial temperature of the object placed in the heating chamber fluctuates, constant baking can be achieved.

(3) Even if the user is located a little far from the heating device,
An alarm sounds to let you know when it's time to turn the food over, so you don't have to constantly monitor the cooking status, and you can use your time more effectively.

4) Even if you leave the appliance unattended while cooking and go out or are unable to cook due to an emergency, it is safe because the heating control will stop after a predetermined time.
