A coffee extraction apparatus includes: a grinder grinding whole beans into coffee powder having a preset size or less and discharging the coffee powder, a grinder inlet defined at a first side of the grinder to introduce the whole beans to the grinder, a grinder outlet defined at a second side of the grinder and discharging the coffee powder, and a first extractor. The first extractor includes: a receiver inlet that faces the grinder and that receives the discharged coffee powder, a filter part receiving the coffee powder through the receiver inlet and extracting coffee liquid by rotating the coffee powder with water of a first temperature, the first temperature being equal to or lower than 25 degrees Celsius, and a receiver that receives the water of the first temperature and that is configured to store the water of the first temperature or the extracted coffee liquid.

Coffee extraction apparatus

A coffee extraction apparatus includes: a first grinder that includes a first burr configured to rotate, a first burr through-hole defined in the first burr in an axial direction of the first burr, a first burr inlet, a first burr outlet discharging coffee powder, a second burr inserted into the first burr through-hole through the first burr outlet to define a grinding space for grinding the whole beans with the first burr, and a burr coupler that supports the second burr and that couples the second burr to the first grinder. The apparatus further includes an extractor that defines an opening on a first side facing the first burr outlet to receive the coffee powder discharged through the first burr outlet and that mixes the coffee powder with water to extract coffee liquid where the burr coupler is configured to selectively separate the first grinder from the second burr.

A coffee extraction apparatus includes: a first burr grinding supplied whole beans, a first burr through-hole defined in the first burr, a first burr inlet receiving the whole beans, a first burr outlet discharging coffee powder, a second burr inserted into the first burr through-hole through the first burr outlet to define a grinding space for grinding of the whole beans with the first burr, a burr coupler coupled to the second burr to move the second burr, a first rotary part coupled to the first burr to rotate the first burr, a second rotary part connected to the burr coupler and rotating to move the burr coupler in an axial direction of the first burr to adjust a depth of insertion of the second burr into the first burr, an extractor that receives and mixes the coffee powder and water to extract coffee liquid.

Coffee extracting apparatus

An indoor unit of an air conditioner, which when a door cover is inserted in the inner side of a front outlet, a door cover moving module moves the door cover in the front-rear direction by the operation of a door cover motor, and when the door cover is moved to the rear of the front outlet, a door housing moving module moves a door cover housing along with the door cover, and thus the door cover may be moved completely to the outside of the front outlet.

Indoor unit of an air conditioner

An air conditioner including a sliding door, which forms a front surface part thereof and moves in a lateral direction to be opened and closed; a sliding door motor for enabling movement of the sliding door; a sliding door position sensor which may include a first position sensor and second position sensor for detecting the position of the sliding door; and a control part for controlling an opening/closing operation of the sliding door based on sensing data of the sliding door position sensor and a rotational speed of the sliding door motor.

Air conditioner

Disclosed is an indoor unit for an air conditioner. The indoor unit for the air conditioner according to the present invention includes: a cabinet assembly forming an external appearance of the indoor unit and having an air suction port formed in a rear of the cabinet assembly; a filter module disposed at the air suction port to filter dust contained in air being introduced through the air suction port; a filter cleaner configured to move upward and downward in a rear of the filter module to remove foreign substances stuck in the filter module; a guide rail vertically disposed on one side of the filter module and configured to guide upward and downward movement of the filter cleaner, wherein the filter cleaner comprises: a mobile gear configured to rotate while engaged with the guide rail to move the filter cleaner upward and downward with respect to the filter module, a gear motor configured to rotate the mobile gear, an agitator configured to rotate in friction with the filter module, a dust container disposed downward of the agitator and collecting foreign substances separated from the filter module due to the rotation of the agitator, and a guide roller bringing the filter cleaner into close contact with the filter module so that part of the agitator rotates while in contact with the filter module.

Indoor unit for air conditioner

Disclosed is an air-conditioner including a front panel forming an appearance of a front portion, a circulator door disposed at the front panel and moving in an up-down direction so as to be opened and closed, a circulator module moving backward based on a product OFF command and moving forward based on a product ON command, and a controller controlling the circulator door to move in a downward direction so as to be opened and the circulator module to move forward based on the product ON command, whereby the circulator door and the circulator module may be efficiently controlled.
