There is an advantage that can upgrade the merchantability.

As described above, the operation panels and the display apparatuses 101, 102, 121, and 131 are installed in the first to second storage bins and the left to right drawer bins, respectively, so that the operating states of the first to second bins and the left to right drawer bins are changed. It is not only operated through the operation panel but also displayed through the display device, and when the operation state and abnormality of each storage room occur, the buzzer sounds as well.

In this case, the operation panels and display devices 121 and 131 for manipulating the set values of the left and right drawer storages 500 and 600 or displaying the operation status are not exposed to the outside when the doors 120 and 130 are not opened. Only when the doors 120 and 130 are opened as an installed hidden type, the operation state and the displayed operation state can be recognized through the operation panel and the display devices 121 and 131.

However, even in the case of a hidden type operation panel and display device that can operate a set value or recognize an operating state only when the door is opened, the key input state is always detected and displayed, which causes power consumption. In addition, there is a problem that the cap sensing value is changed due to the influence of the external environment when the key input is accepted by the cap sensing method of the programmable system on chip (PSOC) device, thereby changing the sensitivity of the key input.

That is, since the capsense method of the PSoC device made as shown in FIG. 3 has a short time for charging and discharging the capacitor C when there is no key input, the period of the sawtooth wave output from the comparator Comp is shortened. The set value of the timer of the PSoC device is expressed as a small value, and when there is a key input, the sawtooth wave is output from the comparator (Comp) because the inherent capacitance value of the capacitor (C) and the capacitance value by the finger are added to increase the time for charging and discharging. Since the period of is increased, the timer setting value of the PSoC device is represented by a large value.

Therefore, the key input is determined as the key input when a timer setting value having a predetermined difference from the timer setting value in the normal state is input.

At this time, as a factor that may affect the sensitivity of the key input, as the period of the sawtooth wave output from the comparator is changed by adjusting the set value of the charging current Ic charged in the capacitor, the set value of the timer is changed. The sensitivity of the input is changed, and when the speed setting value of the timer of the PSoC device receiving the sawtooth period is adjusted, the timer setting value is changed to change the sensitivity of the key input.

However, when the set value of the timer is changed due to the external environment, that is, external temperature or noise, there is a problem in that it is recognized as a key input and a malfunction occurs even though the key input is not actually made as the sensitivity of the key input is changed. .

The present invention has been made to solve the above problems, an object of the present invention is to provide a door when the operation panel is installed in hidden type, respectively installed to set the operating state of each storage compartment of the food storage having a plurality of storage compartments Key inputs can be enabled only when they are opened, minimizing power consumption, and when a door is opened, the factor affecting the sensitivity of key inputs is corrected so that the sensitivity is not changed according to external factors so that stable key input can be achieved. It is to provide a key input method of food storage.

In order to achieve the above object, the present invention provides a key input method of a food storage using an operating panel by a cap sensing method of a PSoC device installed in a plurality of storage rooms, the method comprising: determining a door opening state of a storage compartment, Detecting an external factor when open, resetting a factor of key input sensitivity according to the detected external factor, detecting a key input on an operation panel according to the reset factor, and detecting a key input Determining the door closed state of the storage compartment while accepting the detected key value when the key input is detected, and stopping the detection of the key input when the door is closed by determining the closed state of the door. .

In the present invention, the external factor is an external temperature change or key input noise.

The factor of the keystroke sensitivity in the present invention is characterized by including the charging current and the timer speed.

In the present invention, the operation panel is characterized in that the hidden type is exposed when the door is opened.

According to the present invention, a key input is always input at a constant sensitivity by initializing by correcting a factor of a key input sensitivity that is changed by an external factor when the door is opened to use a hidden type operation panel that can be used only when the door is opened. In addition to being able to achieve this, it is possible to minimize the power consumption by detecting the key input state only when the door is opened.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings, and the same parts as in the prior art use the same reference numerals and names.

The present invention is a key input method in an operation panel by a cap-sensing method of a PSoC device respectively installed in a plurality of storage compartments, wherein the operation panel is applied to a hidden type that is exposed when the door is opened.

First, the door opening state of the storage compartment is determined for key input in the operation panel made in this way (S41).

At this time, when the door is not opened, the key input through the operation panel is not maintained, and when the door is opened, external factors that may affect the sensitivity of the key input are detected (S42).

In the present embodiment, the external temperature is sensed, but the key input noise may also be detected as the key input sensitivity is changed by the noise of the signal other than the key input signal together with the external temperature change.

In this way, by sensing the external factors and resetting and resetting the charging current Ic and the timer speed setting values, even if the key input sensitivity is changed by the external factors, the key input sensitivity is made constant by changing the set value of the timer. S43).

In this way, whenever the door is opened, the factor of the key input sensitivity is reset so that the key input sensitivity is always constant.

After resetting and resetting the key input sensitivity, the key input is sensed and received from the operation panel, thereby preventing the occurrence of a key input error due to external environmental factors (S44).

By resetting the sensitivity of the key input as described above, the door closed state of the open storage compartment is determined while accepting the key input (S45).

Therefore, while the door is opened, the key is continuously detected, but when the door is closed, the key input is stopped to minimize power consumption (S46).

As described above, the present invention minimizes power consumption by enabling key input only when the door is open when the operation panels respectively installed to set the operating state of each storage compartment of the food storage compartment having a plurality of storage compartments are hidden type. In addition, there is an advantage that a stable key input can be made by correcting a factor that affects the sensitivity of the key input when the door is opened so that the sensitivity is not changed according to external factors.
