DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus and method for controlling power of a refrigeration and refrigeration system according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a power control apparatus for a refrigeration and refrigeration system according to an embodiment of the present invention.

The power control apparatus for a refrigeration and refrigeration system according to an embodiment of the present invention includes a power supply unit 110, a switch unit 120, a control unit 130, an operation unit 140, and a power management unit 150, And may further include a display unit 160.

The power supply unit 110 supplies power to operate the refrigeration and refrigeration system.

The switch unit 120 is located between the power supply unit 110 and the control unit 130 and applies or cuts off the power of the power supply unit 110 to the control unit 130 by a switch on /

The controller 130 controls the operation of the refrigeration and refrigeration system by receiving power from the power supply 110. The controller 130 controls the overall operation of the refrigerating and refrigeration system as the power is supplied, Or the like can be used as the control unit 130.

The operation unit 140 is for receiving a user command, and generates an input signal according to a user selection and transmits the generated input signal to the control unit 130.

For example, the operation unit 140 may include a power source menu for selecting power ON / OFF, an UP / DOWN menu for revalidating operation, and the like, A touch menu, or the like.

The display unit 160 displays an operation state using a light emitting diode (LED) or the like based on a user input provided through the operation unit 140. [

The operation unit 140 and the display unit 160 may be implemented as a single unit such as a touch panel to form the display input unit 170. [

When the user inputs a power operation signal (a power-on signal or a power-off signal) through the operation unit 140, the power management unit 150 determines whether the input state of the signal satisfies predetermined input conditions, If the result input condition is satisfied, the switch unit 120 is turned on / off according to the power operation signal input by the user, thereby changing the power application state to the control unit 130 to be applied or blocked.

In one embodiment, the power management unit 150 may set a given delay time as an input condition.

In this case, when the user turns off the power and inputs the power-on signal for a predetermined first delay time (e.g., 3 to 5 seconds) by pressing the power menu of the operation unit 140, the power management unit 150 sets the input condition The switch unit 120 is turned on and power is supplied to the controller 130 to start the operation of the refrigerating and freezing system.

If the power-off signal is generated by pressing the power menu of the operation unit 140 while the user is powered on and the power-off signal is maintained for a second delay time (for example, 3 to 5 seconds) The switching unit 120 is turned off and the power to the control unit 130 is turned off to stop the operation of the refrigerating and freezing system.

Thus, when the user inputs a power menu for power on / off, a certain delay time of, for example, 3 to 5 seconds can be provided to prevent the refrigeration and refrigeration system from suddenly switching to the operation / And can give users the opportunity to make their choices or correct malfunctions.

In another embodiment, the power management unit 150 may set both of the pre-set delay time and the reconfirmation operation as a multiple input condition.

According to this configuration, when the power menu is input, the system is switched to the standby state, and a delay time of about 3 to 5 seconds is provided, so that the user can additionally select Y (yes) / N (no) Reaffirmation procedures may be carried out.

The user can confirm whether or not to confirm / cancel the previously input power on / off signal by selecting one of the Y / N menus, for example, by pressing the up or down menu provided on the operation unit 140. [

Specifically, when a power-on signal is input through the operation unit 140 for a first delay time or more and an acknowledgment signal is additionally input through the operation unit 140, the power management unit 150 determines that the input condition is satisfied, And the operation of the refrigeration and refrigeration system can be started by applying power to the control unit 130. [

If the power-off signal is inputted through the operation unit 140 for the second delay time or more and the confirmation signal is additionally inputted through the reconfirmation operation, the power management unit 150 determines that the input condition is satisfied and turns off the switch unit 120 The operation of the refrigeration and refrigeration system can be stopped by turning off the power to the control unit 130. [

2 is a flowchart illustrating a power control method of a refrigeration and refrigeration system according to an embodiment of the present invention.

First, a power operation signal (a power-on signal or a power-off signal) for turning on or off the power of the refrigeration and refrigeration system is generated and input to the power management unit 150 in accordance with a user input through the operation unit 140 ).

For example, when the user presses the power menu of the operation unit 140 while the power is off, the corresponding power-on signal is transmitted to the power management unit 150 to switch the power management unit 150 to the standby state. When the user presses the power menu of the operation unit 140 while the power is on, the power off signal is transmitted to the power management unit 150 to switch the power management unit 150 to the standby state.

When the user requests power on / off by pressing the power menu of the operation unit 140, the power management unit 150 does not directly perform power on / off in response to the user input, (S120, S150). At this time, the power management unit 150 determines whether the input state of the power operation signal satisfies predetermined input conditions.

If the input condition is satisfied as a result of the determination in S120 or S150, the power management unit 150 performs a switch-on or an off-operation according to the power operation signal input by the user to change the power application state (S130, S160).

In one embodiment, the power management unit 150 may determine that the input condition is satisfied when the power operation signal is input for a predetermined delay time or more (S110 to S120, S110 to S150).

In this case, when the user presses the power menu of the operation unit 140 for a predetermined delay time of about 3 to 5 seconds in the standby state described above and the input of the power on / off signal is maintained for the delay time, On / off < / RTI >

For example, when a power-on signal is input and maintained for a predetermined delay time (S110 to S120), the power management unit 150 turns on the switch unit 120 to apply power to the control unit 130 (S130) The operation of the refrigeration and refrigeration system is started (S140). If the power-off signal is input and maintained for a predetermined delay time (S110 to S150), the power management unit 150 turns off the switch unit 120 to turn off the power to the control unit 130 (S160) The operation of the refrigeration and freezing system is stopped (S170).

In another embodiment, the power management unit 150 may consider whether the power operation signal is input for a predetermined delay time or longer and whether a confirmation signal is additionally input (S120, S150).

For example, if the user presses the power menu of the operation unit 140 for a predetermined delay time or longer, the power on / off signal is input for a predetermined time, and the up / down menu of the operation unit 140 is selected, The power management unit 150 determines that the multiple input condition is satisfied and performs the power on / off operation.

This embodiment will be described in more detail with reference to FIGS. 3 and 4. FIG.

Figure 3 is a flow chart illustrating in more detail some of the steps of Figure 2; 4 is a reference view illustrating an operation state change according to each step of FIG.

In another embodiment described above, step S120 or step S150 in which the power management unit 150 determines whether or not the input condition is satisfied may be subdivided into steps S210 through S250. In FIG. 4, the display input unit 170 integrally embodies the operation unit 140 and the display unit 160 described above.

First, the power management unit 150 monitors whether a power operation signal (power on / off signal) corresponding to a user input is inputted for a predetermined delay time (for example, 3 to 5 seconds) or more (S210).

If the power control signal of the monitoring result in S210 is input for a predetermined delay time or longer, the power management unit 150 switches to the standby state and performs a reconfirmation procedure to inquire whether or not to select confirmation and cancellation subsequently (S220).

For example, as shown in FIG. 4A, when the user presses the power menu D10 of the display input unit 170 for a predetermined delay time, the power menu D10 is turned on to inform the user of switching to the standby state .

When an acknowledgment signal is input by the user (S230), the power management unit 150 proceeds to the next step and monitors whether or not the power operation signal is inputted again over a predetermined delay time (S240).

When the user again presses the power menu D10 to input the power operation signal again for a predetermined delay time or longer, the power management unit 150 determines that the multiple input condition is satisfied (S250), and accordingly, The power supply on / off is performed in accordance with the signal to change the power supply application state.

For example, when the user depresses the power menu D10 for a predetermined delay time of about 3 to 5 seconds (S210) in the state shown in FIG. 4 (a), the power management unit 150 outputs the power- Y or N 'is displayed through the display input unit 170 (S220) to inquire whether to confirm or cancel the operation.

In this state, if the user presses the up-menu D20 to input an acknowledgment signal (S230), a message of Y (yes) (D30) is displayed on the display input unit 170 as shown in Is displayed. If the user inputs a cancellation signal by pressing the down menu D40 (S230), a message of N (no) (D50) is displayed on the display input unit 170 as shown in (c) do.

4 (d), the user again presses the power menu D10 for a predetermined delay time to confirm the input / re-confirmation of the power operation signal When completing the operation (S240), the power management unit 150 determines that the input condition is satisfied (S250), and executes the power on or off operation according to the inputted power operation signal.

The configuration of the power supply control apparatus and method of the refrigeration and refrigeration system according to the present invention is not limited to the above-described embodiments, and various modifications may be made within the scope of the technical idea of the present invention.
