Benefits of technology
[0028] The present invention is achieved to solve the above problems. An object of the present invention is to provide a button display apparatus of a refrigerator which allows the user to easily recognize buttons of a controller of the refrigerator, by condensing light emitted by clicking the buttons on the buttons, button printed units for displaying regions corresponding to the buttons, contact units or light emitting slits.
[0029] Another object of the present invention is to provide a button display apparatus of a refrigerator which prevents the user from being confused about buttons of a controller of the refrigerator, by preventing light of lamps emitted by clicking the buttons from being irradiated to light emitting slits of the other buttons.
[0031] According to another aspect of the present invention, there is provided a button display apparatus of a refrigerator, including: a board having switches for recognizing external operations; lamps mounted on the board around the switches, for irradiating light according to the recognition operations of the switches; a cover installed on the front surface of the button display apparatus, and composed of button printed units; contact units for displaying operation ranges of the user on parts of the button printed units; light emitting slits for transmitting the light of the lamps; and condensing members for covering the paths from the lamps to the light emitting slits, so that the light generated by the lamps can be transmitted through the light emitting slits.
[0032] According to yet another aspect of the present invention, there is provided a button display apparatus of a refrigerator, including: a board; switches installed on the front surface of the board, for recognizing external operations; lamps mounted on the board, for irradiating light according to the recognition operations of the switches; a cover installed to cover the front surface of the board, and composed of button printed units; contact units for displaying operation ranges of the user on parts of the button printed units to correspond to the switches; and condensing members for covering the paths from the lamps to the button printed units, so that the light generated by the lamps can reach the button printed units.
Problems solved by technology
As a result, the user cannot easily distinguish the clicked button from the adjacent buttons.
Accordingly, the intensity of the light irradiated through the light emitting slits 33′ is weakened, so that the user cannot easily identify the buttons.

The present invention discloses a button display apparatus of a refrigerator which can improve an illumination effect of operation buttons by condensing light of lamps for illuminating display characters or contours of the operation buttons on the operation buttons. The button display apparatus of the refrigerator includes: a control board; switches installed on the front surface of the control board, for recognizing external operations; lamps mounted on the front surface of the control board around the switches, for irradiating light according to the recognition operations of the switches; a cover installed to cover the front surface of the control board, and composed of button printed units; contact units for displaying operation ranges of the user on parts of the button printed units; and condensing members for covering the paths from the lamps to the contact units, so that the light generated by the lamps can reach the contact units.
Description
TECHNICAL FIELD [0001] The present invention relates to a button display apparatus of a refrigerator, and more particularly, to a button display apparatus of a refrigerator which can improve an illumination effect of operation buttons by condensing light of lamps for illuminating display characters or contours of the operation buttons on the operation buttons. BACKGROUND ART [0002] In general, a refrigerator includes a controller for controlling a temperature, humidity, illumination etc. of storage chambers such as a refrigerating chamber and a freezing chamber. The controller controls the temperature, etc. of the storage chambers according to the manipulation of the user or the default preset in a built-in storage device. [0003] Preferably, the controller is disposed on a front surface of a door installed on the front surface of the refrigerator for easy use. [0004] Referring to FIG. 1, the controller 20′ of the conventional refrigerator 10 is inserted into the front surface of the...
