It's about how.

In general refrigerators, a compressor is provided on the rear wall of the freezer compartment to perform basic refrigeration and freezing functions, and an evaporator is installed at the rear of the refrigerating compartment or the freezer compartment to form cold air by evaporating the condensed refrigerant sent from the compressor. And a cooling fan for forcibly blowing the cold air cooled by the evaporator into the refrigerating and freezing compartment.

Therefore, a refrigerator compartment and a freezer compartment are respectively formed inside the refrigerator main body, and freezer and refrigerator compartment doors are formed on the front sides of the refrigerator compartment and the freezer compartment so as to store and withdraw food stored therein, and are coupled to be opened and closed. In the refrigerating chamber, a plurality of shelves on which food and the like are seated may be mounted in multiple layers.

In addition to the basic refrigeration function and the dynamic resistance function, refrigerators are generally introduced with a variety of additional functions. Representative examples of these additional features include a dispenser and a foldable home bar. The dispenser is configured to perform the function of supplying filtered water, and the home bar is a space for placing a cup or the like.

It is installed at the front of the door, the user can open the door of the home bar formed on the front of the refrigerator, and can take out the drinks, etc. put in the position, it can also perform a simple bar function to put a cup or the like as described above. Therefore, the power consumption of the refrigerator is also saved by opening and closing the door of the small home bar without opening the door of the refrigerator. A diagram showing such a home bar is shown in FIG. 1.

However, the groove bar structure according to the related art is a manual link type, which is likely to generate an open / close failure or noise. In addition, it is inconvenient for the elderly and people with disabilities to use.

The present invention has been conceived to overcome the disadvantages of the prior art described above, to provide a device and method for automatically opening and closing the home bar by installing a home bar device on the door of the refrigerator and putting a switch for using the same. Has its purpose.

The present invention is a groove bar is formed in the door of the refrigerator to move the groove bar to move up and down in order to achieve the above-mentioned object, and the groove bar to move only a certain distance by the switch to stop automatically as the groove bar moves up and down Provides a device and a method for implementing this home bar device.

To this end, the refrigerator includes a control unit for controlling the refrigerator, a home bar switch for turning on / off the home bar, a first switch and a second switch for stopping the motor driving unit, and a motor driving unit for moving the home bar in the vertical direction. An automatic home bar opening and closing device is provided.

The automatic opening and closing method of the home bar using the refrigerator having such a component may include: checking whether the home bar switch is turned on; driving the home bar motor when the home bar switch is turned on; Checking whether the second switch is turned on; if the second switch is turned on; controlling the motor to stop driving the home bar motor; checking whether the open time of the home bar has exceeded the limit time; If the time limit is exceeded, the control unit drives the home bar motor; if the open time does not exceed the time limit, the control unit determines whether the home bar switch is turned off, and if the home bar switch is turned off, the control unit drives the home bar motor. Verifying whether the first switch is turned on as the home bar motor is driven, and the first switch is If it is turned on, the control unit includes stopping the driving of the home bar motor.

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

2 is a circuit block diagram for automatically opening and closing the home bar of the refrigerator according to the present invention, which includes a control unit 20 for controlling the refrigerator, a home bar switch 21 for turning the home bar on and off, and And switches 22 and 23 for automatically opening and closing the home bar, a motor driving unit 24 and the like. Therefore, when the user presses the home bar switch 21, power is applied to the motor driver 24 to open and close the home bar by driving the motor. The following describes what functions and roles each component of the block diagram having the above structure performs.

The control unit 20 serves to control the function of the refrigerator. When the home bar switch 21 is shorted by the user, the control unit 20 outputs a signal to the motor driving unit 24 so that the home bar motor is driven. In addition, when the first switch 22 and the second switch 23 are short-circuited, a stop signal is output to the motor driver 24 so that the home bar motor is not driven. A diagram showing this structure is shown in FIGS. 4A and 4B. Referring to FIG. 4A, the home bar motor 40 is configured to move the home bar 46 up and down. A gear is attached to this groove bar motor 40 so that the pulley 41 can be rotated by meshing with the opposite gear. The pulleys 41 are disposed in pairs on both sides to provide the rotational force of the motor evenly, thereby stably moving the groove bar 46 up and down.

Since the structure of the pulley 41 is a well-known technique, a description thereof is omitted here. Rings 43 are formed at both ends of the pulley 41, and are connected to the groove bar 46 by a wire 44. Therefore, the groove bar 46 moves up and down as the pulley 41 rotates.

In addition, by installing the first switch 42 and the second switch 45 on the left side to stop the drive of the home bar motor 40 when the ring is touched as the ring 43 moves. That is, it is also possible to configure the switches 42 and 45 in a touch switch structure. Therefore, the home bar 46 is to limit the movement only a certain distance. For example, the first switch 42 may function as an upper limit, and the second switch 45 may function as a lower limit. That is, when the first switch 42 is touched, the home bar 46 is no longer moved upward. Of course, when the second switch 45 is touched, the home bar 46 no longer moves in the downward direction. In order to allow the groove bar 46 to move up and down only a certain distance, a groove 48 is formed in the door, which is illustrated in FIG. 4B. That is, the groove 48 is formed in the door 47.

In addition to the control of only a certain distance described in Figures 4a and 4b, in order to ensure that the home bar is not opened for a certain time, the home bar is automatically closed after a time limit. Because if the home bar is kept open, the cold air in the refrigerator is taken out to prevent the home bar is closed even without the operation of the user's home bar switch 21 after the new limit. The control of the home bar opening and closing is described in detail in the description of FIG. 3.

The home bar switch 21 is installed outside the door of the refrigerator so that a short circuit occurs when the user touches the control unit 20 so as to perform a command to open and close the home bar.

The first switch 22 functions to prevent the home bar 46 from rising upward above the upper limit.

The second switch 23 performs a function of preventing the home bar 46 from descending below the lower limit.

The motor driver 24 drives the home bar motor 40 to move the home bar 46 in the vertical direction. Therefore, the home bar moves in the vertical direction by performing the forward or reverse rotation according to the command of the controller 20.

2 and 4 described above, it is possible to open and close the home bar by moving the home bar 46 up and down. A flowchart showing the opening and closing process of the home bar is shown in FIG. 3. That is, this is a process in which the home bar 46 is automatically opened and closed as the home bar switch 21 is operated, and the home bar motor 40 automatically stops as the home bar 46 moves up and down a certain distance, and also for a predetermined time. The above is the opening and closing control process to automatically close the home bar 46 if the home bar 46 is open. The control process of the home bar opening and closing is as follows.

The control unit 20 is in the standby state until the home bar switch 21 is turned on by the user (step S30).

If it is on, the control unit 20 gives a signal to the motor driving unit 24 to drive the home bar motor 40 (step S31).

As the home bar motor 40 is driven, the home bar 46 descends downward as described with reference to FIG. 4A.

As the home bar 46 descends, the control unit 20 checks whether the second switch 45 is turned on (step S32).

If the second switch 45 is turned on in this step, the control unit 20 stops driving the home bar motor 40 (step S33).

In the state where the home bar 46 is open, the control unit 20 determines whether the home bar opening time exceeds the limit time (step S34). In other words, the control unit 20 checks the time when the home bar is opened and compares the time with the set limit time to check whether the home bar is over.

If the home bar opening time exceeds the limit time in this step, the control unit 20 drives the home bar motor 40 so that the home bar 46 rises upward (step S36).

On the contrary, when the home bar opening time does not exceed the limit time, the controller 20 checks whether the home bar switch 21 is turned off by the user (step S35). As a result of the check, if the home bar switch 21 is turned off, the control unit 20 performs step S36. Otherwise, if the home bar switch 21 is not turned off, the control unit 20 repeatedly performs step S34.

As the home bar 46 rises, the control unit 20 checks whether the first switch 42 is turned on (step S37).

If the second switch 42 is turned on in this step, the control unit 20 stops driving the home bar motor 40 (step S38).
