    Abstract: A linear compressor includes: a piston configured to reciprocate along an axial direction of the linear compressor; a resonance spring configured to elastically support the piston along the axial direction; a motor assembly configured to provide a driving force to the piston, the motor assembly including a magnet that is disposed radially outside the piston; and a supporter configured to be coupled to the piston, the magnet, and the resonance spring. The supporter includes: a piston coupler coupled with the piston; a magnet coupler coupled with the magnet; and a spring coupler coupled with the resonance spring. The piston coupler, the magnet coupler, and the spring coupler are integrally formed by aluminum die casting.

    Abstract: A linear compressor includes a shell, a frame in the shell, a cylinder defining a compression space, a piston in the cylinder, a motor assembly configured to drive the piston, a discharge cover unit defining a discharge space, a discharge valve configured to selectively open and close the compression space, and a valve spring assembly configured to provide elastic force that causes the discharge valve to contact the cylinder. The discharge cover unit includes a cover housing that defines an opening configured to communicate with the discharge space, a discharge cover that inserts into the cover housing through the opening, that contacts an inner surface of the cover housing, and that covers the opening, and a fixing ring configured to be positioned at an inner surface of the discharge cover. A thermal expansion coefficient of the fixing ring is greater than that of the discharge cover.

    Abstract: An operating method of a remote control device according to an embodiment of the present invention includes searching at least one of the image display device and external devices, and acquiring device information on at least one of the searched image display device and external devices. The remote control device receives an input first fingerprint for a user preference setting operation of setting at least one of the image display device and external devices to a personalized setting of a user, and acquires user preference setting information including a setting value of the user preference setting operation on the basis of the acquired device information and a first fingerprint image corresponding to the input first fingerprint. The remote control device sets the image display device or external device corresponding to the acquired user preference setting information to the personalized setting of the user corresponding to the first fingerprint on the basis of the user preference setting information.

    Abstract: A linear compressor includes a shell, a discharge pipe coupled to the shell, a compressor main body located inside of the shell, a cover housing that defines a discharge space that discharges refrigerant to the discharge pipe, and a guide pipe coupled to the cover housing and configured to guide refrigerant from the discharge space to the discharge pipe. The cover housing includes a flange portion configured to couple to the compressor main body, a chamber portion that extends from the flange portion and that defines the discharge space, an accommodation groove configured to accommodate the guide pipe, and a communication groove that penetrates an inner wall of the accommodation groove and that extends to the discharge space. The guide pipe is configured to insert into the communication groove in a state in which the guide pipe is accommodated in the accommodation groove.
