摘要：
A refrigerator comprising a cabinet (10) forming a storage space, a door (40) opening and closing the cabinet (10) and having an opening (403) communicated with the storage space, and a detection device (82) provided in the door (40) for detecting a user's operation,wherein the refrigerator comprises: a lighting unit (85) turned on or off by a signal of the detection device (82) operated by the user while the door (40) is closed, and illuminating an inside of the refrigerator; and a panel assembly (54) provided to cover the opening (403) and through which light is transmitted to the outside of the refrigerator so as to allow the user to selectively view the inside of the refrigerator by turning on/off of the lighting unit (85).
技术问题语段：
The technical problem addressed in this patent is the inconvenience of checking the contents of a refrigerator without opening the refrigerator door, as this may result in the leakage of cooling air and the need to open the main door. The patent proposes a solution using a front panel with a half mirror and insulation panels to allow for easy access to the refrigerator without opening the entire refrigerator door.
技术功效语段：
The present invention is about a method for controlling a refrigerator that allows the doors to open and close one space by rotating them. This can be applied to different types of refrigerators, such as those with a bottom freezer compartment. The technical effect of this invention is to improve the refrigerator's performance and efficiency.
权利要求：
1. A refrigerator comprising a cabinet (10) forming a storage space, a door (40) opening and closing the cabinet (10) and having an opening (403) communicated with the storage space, and a detection device (82) provided in the door (40) for detecting a user's operation, wherein the refrigerator comprises: a lighting unit (85) turned on or off by a signal of the detection device (82) operated by the user while the door (40) is closed, and illuminating an inside of the refrigerator; and a panel assembly (54) provided to cover the opening (403) and through which light is transmitted to the outside of the refrigerator so as to allow the user to selectively view the inside of the refrigerator by turning on/off of the lighting unit (85); wherein the detection device (82) is a knock detection device provided on a rear surface of the panel assembly (54) and detecting a knocking operation on the panel assembly (54) by the user; wherein the panel assembly (54) comprises a front panel (541) formed of a see-through material, the front panel having a bezel (5411), and wherein the knock detection device (82) is installed at the area of the bezel (5411) of the front panel (541).
2. The refrigerator according to claim 1, wherein the panel assembly (54) comprises: the front panel (541) forming a front surface of a sub-door (50) and being formed of a half mirror reflecting a part of the light and transmitting a part of the light to be selectively transparent; a plurality of insulation panels (542) spaced apart from the front panel (541) and formed of transparent tempered glass; and a spacer bar provided between the front panel (541) and the insulation panel (542) next to the front panel (541) and between the plurality of insulation panels (542), and separating and sealing between the front panel (541) and the insulation panel (542) and between the plurality of insulation panels (542).
3. The refrigerator according to claim 2, wherein the front panel (541) is configured with a glass layer (5413) formed of transparent glass, a vacuum deposition layer (5414) formed on a rear surface of the glass layer (5413) by vacuum deposition of a titanium compound, and a bezel layer (5415) printed on a rear surface of the vacuum deposition layer (5414) along an edge of the glass layer (5413) so as not to transmit light.
4. The refrigerator according to claim 3, wherein the front panel (541) further comprises a transparent print layer (5416) printed on the entire rear surface of the vacuum deposition layer (5414) with a transparent material.
5. The refrigerator according to claim 2, wherein the front panel (541) comprises: a glass layer (5413) formed of transparent glass; a ceramic print layer (5417) formed to be heated on a front surface of the glass layer (5413) after screen printing with a reflective ink including a titanium compound; and a bezel layer (5415) formed along an edge of a rear surface of the glass layer (5413) and printed so as not to transmit light.
6. The refrigerator according to claim 2, wherein the front panel (541) comprises: a glass layer (5413) formed of transparent glass; a hard coating layer (5418) coated on a front surface of the glass layer (5413) with a triple layer of iron, cobalt and chrome; and a bezel layer (5415) formed along an edge of a rear surface of the glass layer (5413) and printed so as not to transmit light.
7. The refrigerator according to claim 5 or claim 6, wherein the bezel layer (5415) is printed with a ceramic pigment including glass powder.
8. The refrigerator according to claim 5 or claim 6, wherein the glass layer (5413) is a gray colored glass.
9. The refrigerator according to claim 5 or claim 6, wherein the ceramic print layer (5417) or hard coating layer (5418) is formed so that the front panel (541) has a 20%-30% of light transmittance.
10. The refrigerator according to any one of claims 2 to 9, wherein a space between panels (541, 542) spaced apart based on the spacer bar is filled with an inert gas or vacuum treated for heat insulation.
11. The refrigerator according to any one of claims 2 to 10, wherein the front panel (541) forms the entire front surface of the door (40), and the next insulation panel (542) is formed to have a further smaller size than the front panel (541) and is disposed in an inner side area of the front panel (541).
12. The refrigerator according to claim 11, wherein a bezel layer (5415) printed not to transmit the light is formed on an edge of the front panel (541) of an outer side of the insulation panel (542) next to the front panel (514).
13. The refrigerator according to claim 11, wherein the detection device (82) is provided on the bezel layer (5415) so as not to be exposed to the outside.
