Abstract

PURPOSE:To provide a microwave heating device in which the demonstration mode is protected from being unintentionally set or released by incorporating a key-entry number memory means and a demonstration mode setting means. CONSTITUTION:A key entries memory means 8 in a micro computer 14 counts and memorized the number of entries as certain key entries are made to set the demonstration mode. Upon completing the key entries to set the demonstration mode, it outputs a signal to a demonstration mode setting means 7, which sets the demonstration mode based on such input. By this constitution, there is little risk in which the demonstration mode is set by the consumer. Further, such risk can also be avoided as the demonstration mode is released at dealership, etc., and a fire is caused due to performing the heating without the foodstuff being set.

Description

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

Conventional technology demonstration mode can be set by inputting two specific keys alternately multiple times, or only when a specific key is input a specific number of times, and then another specific key is input a specific number of times. There is a way to set it.

Problem to be Solved by the Invention However, in the former case, since the setting is easy, the demonstration mode is set by the consumer.
There is a problem in that when cooking is performed, no output signal is sent to the heating means, so the cooking cannot be done at all. In addition, in the latter case, if the demonstration mode has been set at a store etc., the demonstration mode will be canceled by inputting the second specific key. There is also the problem that even though an output signal is sent and there is no food in the container, there is a danger that it will heat up and burn.

The present invention solves these conventional problems, reduces the risk of consumers setting the demonstration mode, and what is more, it reduces the risk of consumers setting the demonstration mode. The present invention provides an excellent high-frequency heating device with improved quality that will not be released.

Means for Solving the Problems In order to achieve the above object, the high frequency heating device of the present invention has a key input number storage means and a demonstration mode setting means, whereby a specific key is input a specific number of times, After that, the demonstration mode is set only when another specific key is entered a specific number of times, and if a specific key is entered more than a specific number of times, and during the setting. If a key other than a specific key is input, the key input count storage means returns to the initial state, but if the second specific key is input multiple times or more, the once set demonstration mode is canceled. This means that it will not be done.

Operation The high-frequency heating device of the present invention is set only when a specific key is input a specific number of times and then another specific key is entered a specific number of times when setting the demonstration mode. If a specific key is entered more than a specific number of times or if a key other than the specific key is entered, demonstration mode will not be set, so demonstration mode will not be set by the consumer. In addition, if the second specific key is pressed more than a certain number of times, the demonstration mode that has been set will not be canceled, so the demonstration mode that has been set at a dealer etc. This will greatly help improve the quality of the high-frequency heating device, since the mode will not be canceled and there is no risk of erroneous heating and combustion.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing the configuration of a high-frequency heating device according to an embodiment of the present invention. The key input number storage means 8 in the microcomputer 14 counts and stores the number of inputs when a specific key input is made to set the demonstration mode, and when the key input for setting the demonstration mode is completed, the key input number storage means 8 stores the number of inputs. The demonstration mode setting means receives the output signal and sets the demonstration mode.

FIG. 2 is a flowchart diagram illustrating a method for setting demonstration mode. When a key is entered (
In step 16), it is determined whether the key is a specific key for setting the demonstration mode.
), if it is a key input other than the key for setting the demonstration mode, the key input number storage means is returned to the initial state (step 17). If a specific key input is used to set the demonstration mode, the key input number storage means is counted up by one (step 18), and it is determined whether the specific number of inputs has been reached (step 19). When the number of keystrokes is reached, the demonstration mode is set (step 20), and when the number of keystrokes is exceeded, the keystroke number storage means is returned to its initial state (step 21). These are performed by the control means.

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

(1) Demonstration mode is set only when a specific key is entered a specific number of times and another specific key is entered a specific number of times, so the demonstration mode is set by the consumer. There is almost no danger.

(2) Even if the second specific key is pressed more than a certain number of times, the demonstration mode that was set at the store etc. will be canceled so that the demonstration mode that has been set will not be canceled. There is no danger of combustion due to heating even though there is no food in it.

As a result of the above, the present invention is greatly useful for improving the quality of high-frequency heating devices.
