Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a high-frequency heating device with a heater using a microcomputer.

Among the cooking menus of conventional high-frequency heating devices with heaters, there are cooking menus that use output data from humidity measuring means, but if the cooking using the heater is finished, the inside of the refrigerator will be in a high temperature state. Since there is a risk of erroneously measuring the humidity inside the refrigerator, in most cases, the temperature inside the refrigerator at the time of setting is measured, and if the temperature inside the refrigerator is high, the output signal from the cooking start instruction means is A method is used in which the cooking does not start even if an input is received, and the output signal from the cooking start instruction means is received when the temperature inside the refrigerator becomes low.

Problems to be Solved by the Invention However, if there is no temperature detection element to measure the temperature inside the refrigerator, it is difficult to directly measure whether or not the temperature inside the refrigerator is high, so cooking may continue even when the temperature is high. There are problems such as deterioration of cooking performance due to The present invention
This problem is solved by providing an excellent high-frequency heating device that can improve cooking performance without using a temperature detection element and reduce costs.

Means for Solving the Problems In order to achieve the above object, the high-frequency heating device of the present invention has a cooking end determination means, an internal temperature determination means, and a mask time setting means, which allow the high-frequency heating device to determine when the cooking is completed according to the state of use of the heater cooking. The temperature inside the refrigerator is determined, and if the temperature is high,
The time for masking the output signal from the cooking start instruction means is set by the mask time setting means.

Function The high-frequency heating device of the present invention uses calculations to determine the internal temperature at the end of heater cooking or when the heater is plugged in. Therefore, the start of cooking in a high temperature state can be masked for a certain period of time, and the high-frequency heating device always Since cooking can be started at a low temperature, there will be no erroneous measurement of internal humidity, which can greatly contribute to improving cooking performance. At the same time, since there is no need to use a temperature detection element to measure the temperature inside the refrigerator, it is also useful for reducing costs.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 2 is a perspective view of the main body of a high-frequency heating device according to an embodiment of the present invention. A door 202, a display tube 11, and a key operation section 204 are provided on the front surface of the main body 201.

203 is a heating chamber in which food is placed.

FIG. 1 shows a configuration diagram of an embodiment. The cooking setting means 3 in the microcomputer 15 includes a cooking key 1 which is an input means for setting cooking in the key device section 204 shown in FIG.
By operating , the cooking mode is written, and then by operating the cooking time setting key 2, which is also a cooking setting input means in the key operation section 204, an appropriate cooking time is set. Once the cooking mode and cooking time have been set, the control means 6 turns on and off the relay 12, which is the load control means, in response to a signal from the start key 4, which is the cooking start instruction means in the key operation unit 204, thereby starting the high-frequency heating. The magnetron 13, which is the means, or the heater 14, which is the heater heating means, oscillates, and the object to be heated is heated. At the same time, the cooking time set by the cooking setting means 3 is counted based on the signal from the start key 4, and the cooking completion determining means 7 determines whether or not cooking is complete.

As a result, when it is determined that cooking is completed, the internal temperature determining means 8 calculates the internal temperature according to the usage state in the case of heater cooking. Also, even when plugging in,
The internal temperature of the refrigerator is determined by the above-mentioned internal temperature determining means 8 based on the signal from the circuit vicinity temperature measuring means 10. Thereby, if the temperature inside the refrigerator is high, a certain fixed time is set by the mask time setting means 9. This mask time is constantly counted down from the end of heater cooking or after plug-in, and when cooking is set using the output data from the humidity measuring means 5 with mask time remaining, the start key is pressed. The signal from 4 is masked for the remaining mask time, and at the same time, the display tube 11, which is the display means, shows the following:
A hot sign is displayed indicating that the temperature inside the refrigerator is high. The display tube 11 also displays cooking mode, cooking time, etc., which are controlled by the control means 6 described above.
It will be held at The above mask time setting method is shown in Figures 3 to 4.
It is shown as a flowchart in the figure.

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

(1) Depending on the temperature inside the refrigerator, if the temperature inside the refrigerator is high, the start of cooking can be masked, so deterioration of cooking can be prevented and cooking performance can be improved.

(2) Since the temperature inside the refrigerator is determined by calculation or the like within the microcomputer, there is no need to measure it using a temperature detection element, and costs can be reduced.
