Description

Air conditioner and method for manufacturing mirror for attaching air conditioner Technical Field The present invention relates to an air conditioner and a method for manufacturing a mirror for attaching an air conditioner, and to an air conditioner to which a mirror is attached and a method for manufacturing the mirror. Background An air conditioner is a device that adjusts the temperature of air in a room to a temperature set by a user. In order to cool and heat indoor air, the air conditioner may supply heat-exchanged air to an indoor space. In recent years, various new functions related to the operation of an air conditioner have been added, and concepts such as an intelligent air conditioner and an intelligent air conditioner have been continuously developed. The air conditioner disclosed in korean laid-open patent No. 10-2018-01382270 includes a radar sensor that measures a heart rate of a user within a prescribed distance from the air conditioner. In the conventional air conditioner, the radar sensor is exposed to an external panel of the air conditioner. Since the radar sensor senses a user through electromagnetic waves, there is a problem in that it is difficult to measure a signal of the user without exposing the radar sensor outside the panel. In addition, since the radar sensor is exposed to the outside, there is a problem in that it may be contaminated with dust, foreign matter, or the like, and the accuracy of the sensor is lowered. This problem not only affects the aesthetic appearance of the air conditioner, but may also cause inconvenience in use of the air conditioner. In addition, when a display for displaying operation information of the air conditioner is disposed on the front surface of the air conditioner, there is a problem in that it is difficult to attach a mirror in front of the display. Prior art literature Patent literature Patent document 0001 Korean laid-open patent publication No. 10-2018-01382270A (publication date: 2018.12.31). Disclosure of Invention The invention provides an air conditioner in which a mirror is attached to the front of a casing and a radar sensor and a display device are smoothly operated. Another object of the present invention is to provide an air conditioner in which the reflectance of a mirror is uniform between a region corresponding to a display device and other regions. Another object of the present invention is to provide an air conditioner that can improve the aesthetic feeling by preventing the rear of a mirror other than a display or a sensor for transmitting/receiving signals, which is disposed in the air conditioner. Another object of the present invention is to provide a method for manufacturing an air conditioner attachment mirror capable of achieving the above object. The problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description. In order to achieve the above object, an air conditioner according to an embodiment of the present invention includes a case having a suction port and a discharge port, the case including a front wall, a mirror disposed in front of the front wall, a display device and a radar sensor disposed behind the mirror, the mirror including a glass panel, a first layer formed on a rear surface of the glass panel and including tin, and a second layer formed on a rear surface of the first layer and shielding a rear surface of the glass panel except for a region corresponding to the display device and the radar sensor. An opening may be formed in the front wall, and the display device and the radar sensor may be disposed in the opening. In the mirror, a translucent third layer may be formed in a region corresponding to the display device in a rear surface of the first layer. A fourth layer protecting the display device and the radar sensor may be formed in a region where the second layer is not formed in the rear of the first layer. A synthetic resin film may be formed on the back surface of the second layer. A fifth layer may be formed between the glass panel and the first layer. An adhesive member may be included between the front wall and the mirror. A method for manufacturing a mirror attached to a front wall of an air conditioner provided with a display device and a radar sensor according to an embodiment of the present invention includes a step of forming a glass panel, a step of forming a first layer including tin on a back surface of the glass panel, and a step of forming a second layer shielding a rear surface of the glass panel in a region other than a region corresponding to the display device and the radar sensor on the back surface of the first layer. A step of forming a translucent third layer in a region corresponding to the display device in the back surface of the first layer may be included. The method may further include forming a transparent fourth layer
