As a result, the target temperature inside the storage compartment (the freezer compartment and the refrigerator compartment) displayed on the status display window 420 of the refrigerator below the portion where the control icon and the path are displayed is increased.

In order to achieve this target temperature, the operation rate of the compressor (see FIG. 2, 310) is lower than before or its operating frequency is decreased.

As shown in FIG. 6, when the user touches the control icon 400 and drags it in the state to move to the other end of the movement path 410, the refrigerator operates in a direction in which power consumption of the refrigerator increases gradually. The target temperature inside the storage compartment (the freezer compartment and the freezer compartment) displayed on the status display window 420 is lower than before.

To achieve this target temperature, the operating rate or operating frequency of the compressor (see FIG. 2, 310) is increased.

The state display window 420 also shows the current state of the compressor, and also changes in the operation state of the compressor by the operation of the control icon 410 described above.

A power information display window 430 is provided below one side of the status display window 420. The power information display window 430 includes a graph display unit 431 and a color display window 432 for displaying a graph of a change in power rates to be described later. ), And a power consumption display window 433 that displays the power consumption of the entire home and the power consumption of each electric product by numbers.

As shown in FIG. 7, the graph display unit 431 displays a change graph 431a of the actual power consumption (or actual power rate) of the current home safety body. In addition, a graph 431b indicating a change in the average value of the power consumption amount (or power rate) of the homes to which the power company or the power service company supplies power is displayed.

The straight line extending up and down in the graph display unit 431 is a time display line 500 indicating the current time.

Here, the change graph 431b of the average value of power consumption (or power rate) used in each home is provided by a power company or a power service company as described above, and based on this, it is judged that the power consumption of the home safety body is appropriate. It is desirable to.

Therefore, hereinafter, the average value of the strategic consumption amount (or power rate) used in various households will be referred to as the first reference power consumption amount (or first reference power rate).

Here, the first reference power consumption (or first reference power charge) provided by the power company is not fixed, but may vary from day to day, and the average reference consumption (or first reference power charge) may also be changed according to power demand hourly. This is the value that changes.

On the screen by the display module (refer to FIG. 6, 241), the actual power consumption (or power charge) graph 431a and the first reference power consumption (or first reference power charge) graph 431b of the current home safety body. Is preferably overlapped to allow comparison at a glance.

On the other hand, there is a reference line 600 provided in a date form on the left and right on the graph, the reference line 600 is a second reference power amount (or second reference power rate) set by the user or set by the power company. It is desirable to define a higher billing period, that is, a section in which the electricity bill is significantly higher than the baseline.

The comparison between the actual power consumption (or power rate) and the first reference power consumption (or first reference power charge) is a relative comparison with the user's home and other households using the first reference power consumption (or first reference power charge). to be.

It has a feature that makes it easy for users to see how their home's power consumption pattern compares with other homes.

However, the second reference power consumption amount (or second reference power rate) has a function of allowing the user to set a target value of the actual power consumption amount (or actual power rate).

Thus, by comparing the second reference power consumption (or second reference power charge) with the actual power consumption (or actual power charge), the current power usage pattern of the current own home can be viewed and the target value can be observed, or If the set reference value is exceeded, the user can provide a motif to reduce the value exceeded by the user's choice.

Here, the high billing period is defined as a section exceeding the reference line 600. Therefore, the reference line 600 is the lower limit of the high billing section.

That is, the first reference power consumption (or first reference power charge) provides a kind of relative reference value, and the second reference power consumption (or second reference power charge) provides a kind of absolute reference value.

One side of the graph display unit 431 is provided with a color display window 432, which is preferably provided in the form of a traffic light including a red window 432a, a yellow window 432b, and a green window 432c.

Accordingly, the reason why the color display window in the form of a traffic light is provided is that current power consumption (or power charge) in the home exceeds or equals or falls short of the first reference power consumption (or first reference power charge). If so, this status is to inform you.

In addition, a comparison result between the actual power consumption (or power rate) and the second reference power consumption (or second reference power rate) may be displayed using the color display window 432.

Looking at the flow of the refrigerator controlled by the movement of the control icon under the configuration as shown in FIG.

First, power consumption of the refrigerator and state information of components (compressor, ice maker, etc.) are displayed on the display unit provided in the display module (S801).

In this state, it is determined whether there is an input for changing the operation mode of the refrigerator. Here, the input for changing the operation mode means that the user touches and drags the control icon to change the position of the control icon on the movement path and then touches it. It will be a case of dropping the hand (S802).

If it is determined that a change in the position of the control icon for changing the operation mode has occurred, it is determined whether the change in the position of the control icon is related to an increase in the freezing / freezing capacity (or power consumption) of the refrigerator or a decrease (S803). ).

Here, the change of the position of the adjustment icon for increasing the freezing / refrigeration capacity of the refrigerator will occur when the user determines that the freezing / refrigeration capacity of the refrigerator is insufficient or exceeds the standard that he or she thought.

 When it is associated with an increase in the freezing / refrigeration capacity (or power consumption) of the refrigerator, the target temperature of the refrigerating compartment or the freezing compartment is set to be lowered, and the set target temperature is displayed on the status display window in the display unit of the display module (S804).

Then, the compression capacity is increased, such as an increase in the operation rate or operating frequency of the compressor, and information related thereto is displayed on the status display window (S805).

At the same time, the increased estimated power consumption is displayed to allow the user to know this (S806).

Meanwhile, in step S803, when a control command is received in a direction of decreasing freezing / refrigeration capacity, first, a target temperature of the refrigerating compartment or the refrigerating compartment is set to increase, and the set target temperature is displayed on the status display window (S807).

Then, the operation rate or the operating frequency of the compressor is set to be reduced, so that the compression capacity of the compressor is set to be reduced, and the change in the driving capacity of the compressor is displayed on the status display window (S808).

In addition, the expected power consumption to be reduced in the future by the control is displayed so that the user can see the change in power consumption (S809).

Meanwhile, as described above, the display module is provided with a power information display window (refer to FIG. 7 and reference numeral 430). Hereinafter, with reference to FIG. 9, a state according to a change in the actual power consumption (or power rate) used at home is shown. Let's look at how to control the display.

Here, the first reference power consumption amount (or first reference power charge) and the second reference power consumption amount (or second reference power charge) will be described as a reference power consumption amount (or reference power charge).

As shown in Fig. 9, first, the refrigerator operates (S801), and when power starts to be consumed, whether the current actual power consumption (or actual power charge) is less than the reference power consumption (or reference power charge). Or it is determined whether the same range or exceed (S802).

If it is determined to be insufficient, light enters the green window (see FIG. 7 and 432c) provided in the color display window (see FIG. 7 and 432), and green light is displayed outside (S903).

Through this, the user can easily recognize that the current electricity consumption or power bill in his home is lower than other homes.

On the other hand, when the determination result in the step S802 is in the same range, the yellow light (see Fig. 7, 432b) of the color display window (see Fig. 7, 432) is light, the yellow light is remarkably outstanding to the outside. (S904).

Here, the same range is preferably defined as a range of about 95 to 100% of the reference power consumption (or reference power charge), but is not limited thereto, and the range may be changed according to circumstances.

Therefore, if the actual power consumption (or actual power charge) in the home is in the range of 95 to 100% of the reference power consumption (or reference power charge), the yellow window is lighted to display a kind of warning to the user. Serves.

On the other hand, if it is determined in S902 that the actual power consumption (or actual power charge) in the household exceeds the reference power consumption (or reference power charge), the excess state is notified in a noticeable manner to the user. The light enters the red window (see FIG. 7, 432a) of the color display window (see FIG. 7 and 432), and the red light is displayed on the outside (S905).

Thus, the user can easily recognize that the current state of power consumption is outside the normal power consumption pattern of a general household.

On the other hand, when the refrigerator operates in a state in which the power consumption exceeding the red light is displayed on the color display window as described above, a power management program provided by a power company (or a power service company) according to a user's intention or to reduce power bills In operation S906, it is determined whether the power consumption reduction operation is set.

Thus, when it is determined that the power consumption reduction operation is set, the refrigerator is issued a command to reduce the operation rate or the operating frequency of the compressor, or a command to reduce the power consumption during the defrosting operation of the defrost heater (S907).

If the power consumption reduction operation is set for other electric appliances in addition to the refrigerator, each electric appliance will be controlled in a direction that can reduce the current electric power consumption according to the setting.

In this state, the current actual power consumption (or actual power charge) is compared with the reference power consumption (or reference power charge) in real time, and the result is displayed in different colors as described above.
