Abstract

PURPOSE: A device for controlling a clock of a refrigerator is provided to control the time for various clocks with a central communication system by transmitting and receiving time data into many clocks using a time circuit of the refrigerator. CONSTITUTION: During a common operation of a refrigerator(step100), time is displayed in a display unit of the refrigerator through a driving circuit of display by counting the present time with an oscillation circuit for clock. When a user establishes an operating routine of time through an operating unit(step200) in on state, a radio frequency module is "enable" by feeding time data into a microcomputer(step300). When the user inputs time data through an operating unit of refrigerator and pushes a transmitting key, time data converted through an interface circuit is transmitted to the radio frequency module through a transmitting unit(step400). The transmitted data is converted through a converting unit by feeding to a receiving unit stuck to a certain position of the clock. When the time data is received, the microcomputer checks if the operating routine of clock is finished after establishing the time for many clocks through a driving unit of time(step500). When the operating routine of clock is finished(step700), the time of clock is displayed with a central communication system by disabling the radio frequency module(step600).

Description

Clock control of the refrigerator.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clock control apparatus of a refrigerator, and more particularly, to a clock control apparatus of a refrigerator that enables centralized time control by transmitting and receiving time data of a clock circuit of a refrigerator to a plurality of clocks.

Generally, a clock is attached to each home or various places to represent time, and usually one or more clocks are provided.

However, when trying to adjust the time for these multiple clocks, the user has to manually adjust the time manually.

In addition, there is a problem that it is not easy to adjust the time of the clock which is usually located in a high place.

The present invention was created in order to solve the above problems, the clock control of the refrigerator to control the time for a plurality of clocks centrally by transmitting and receiving time data using the clock circuit of the refrigerator to a plurality of clocks The purpose is to provide a device.

The clock control apparatus of the refrigerator according to the present invention is a device for centrally controlling time by transmitting time data of the refrigerator to a plurality of clocks by using a radio frequency, and a transmitter for transmitting data about time to a radio frequency module. Wow; A receiving unit attached to a predetermined clock and receiving time data transmitted from the transmitting unit and converting the received time data; And a time driver configured to display the time on the clock in the same manner as the time converted by the receiver.

According to one aspect of the present invention, there is provided a clock control apparatus of a refrigerator, the refrigerator comprising: a transmitter configured to transmit data about a time to a radio frequency module; A receiving unit attached to a predetermined clock and receiving time data transmitted from the transmitting unit and converting the received time data; And a time driver configured to display the time on the clock in the same manner as the time converted by the receiver.

According to a feature of the present invention configured as described above, the clock control apparatus of the refrigerator according to the present invention to provide a convenience to the user by centrally controlling the time for a plurality of clocks using the clock circuit of the refrigerator.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The clock control apparatus of the refrigerator of the present invention, referring to FIG. 1, includes: a transmitter 5 for transmitting data on time controlled by the clock circuit of the refrigerator to a radio frequency module; A receiving unit 8 attached to the plurality of watches 11 and receiving time data transmitted from the transmitting unit 5 and converting the received time data; And a time driver 10 for displaying the time on the clock 11 in the same manner as the time converted by the receiver 8.

In more detail, the clock control apparatus of the refrigerator of the present invention includes an operation unit 1 that enables the clock control apparatus to be turned on / off by the user's selection.

Then, the time is counted by a clock oscillation circuit 2 of the refrigerator, and data about the time is applied to the microcomputer 3.

When the user operates the clock control device by the operation unit 1, the high frequency signal of the transmitter 5, that is, the R / F module (Radio Frequency Module) is transmitted through the interface circuit (4). Enabled.

During normal operation of the refrigerator, the time is displayed on the refrigerator display unit 88 segment 7 through the display driving circuit 6.

On the other hand, the R / F module (Radio Frequency Module) receiving unit 8 is attached to a predetermined position of the plurality of clocks 11 to receive data about time from the transmitting unit 5.

The receiver 8 receives the unique transmission signal from the transmitter 5 described above and applies the signal to the converter 9, which amplifies and decodes the received signal.

The converter 9 is amplified by the RF amplifier when the RF signal (radio frequency signal) is applied, detected and demodulated and output.

The data converted through the converter 9 is applied to the time driver 10, and displays the time of the clock 11 in the same manner as the time received from the transmitter 5.

Next, the control process of the clock control apparatus of the refrigerator according to the preferred embodiment of the present invention including the above-described component will be described in detail with reference to the flowchart of FIG. 2.

First, during normal operation of the refrigerator (step 100), the current time is counted by the clock oscillation circuit and the time is displayed on the display unit of the refrigerator through the display driving circuit.

When the user sets the clock operating routine on through the operation unit (step 200), the clock data is applied to the microcomputer and the radio frequency module is enabled. (Step 300)

At this time, when the user inputs the time data through the operation unit of the refrigerator and presses the transmit key, the time data converted through the interface circuit is transmitted to the radio frequency module through the transmitter.

The transmitted data is applied to a receiving unit attached to a predetermined position of the watch to change the data through the converting unit.

When the time data is transmitted, after the time for the plurality of clocks is set through the time driver, the microcomputer determines whether the clock operation routine is completed (step 500).

When the clock operating routine is completed, the radio frequency module is disabled (step 600), and the time of the clock is displayed centrally (step 700).

The clock control apparatus of the refrigerator according to the present invention enables the centralized control of a plurality of clocks simply by transmitting and receiving data through the clock circuit of the refrigerator.

And, when adjusting the time for a plurality of clocks, the user can easily control the clocks by turning on the operation unit of the clock control device of the refrigerator without manually operating the clocks respectively.

In addition, even when changing the time of the clock located in a high place it is possible to conveniently control the clock through the clock control device of the refrigerator without the user using the chair or the base.
