A control circuit for controlling a power supply including a first switch and a second switch coupled in series between a first potential and a second potential. The control circuit includes a detection circuit that detects a magnitude relation of a voltage value at a node between the first and second switches and a reference value during a period in which the first switch and the second switch are inactivated. The detection circuit generates a control signal corresponding to the magnitude relation. A regulation circuit regulates a switching timing of the second switch in response to the control signal to decrease a difference between the voltage value at the node and the reference value.

An indoor unit of an air-conditioning apparatus is provided, in which an air-conditioning condition changed based on a gesture corresponds to an air-conditioning condition displayed on a display device of a remote controller. With an indoor unit 100, when a user U1 performs a predetermined motion (S1-1), a controller 70 determines the motion of the user U1 (S1-2), recognizes that a gesture instruction condition is instructed (S1-3), controls a heat exchanger 4 and other devices based on the gesture instruction signal (S1-4), and causes the gesture instruction signal to be sent to a remote-controller communication device 85 (S1-5). When a remote controller 80 receives the gesture instruction signal (S1-6), the gesture instruction condition is displayed on a remote-controller display device 82 (S1-7), and buzzer sound (electronic beeper sound) is output from a remote-controller sound output device 83 (S1-8).

When a user thinks “Is it a malfunction?” and wants to relieve this doubt and worry, the user first pushes a menu button 83b on the remote control 80 and further pushes a minus button 83c or a plus button 83a to set the cursor on the “In a case such as . . . (inquiry menu)”. Here, when the set button 83e is pushed, two menu items, namely, “During heating operation . . . ” and “From the outdoor unit . . . ” are displayed. Further, when the set button 83e is pushed while the cursor is set to the “During heating operation . . . ”, “The horizontal flaps will be in a horizontal state at the start of operation, during defrosting, and when temperature has become above the set temperature. It is not a malfunction” is displayed on the display unit 82.

An indoor unit includes a casing having a suction port formed on an upper portion and a blow-out port on a lower side of a front surface portion, an axial-flow or mixed-flow fan provided on the downstream side of the suction port in the casing, and a heat exchanger provided in the casing at a position on the downstream side of the fan and on the upstream side of the blow-out port. The heat exchanger includes a plurality of fins arranged side by side with predetermined gaps therebetween and a plurality of heat-transfer tubes penetrating through the plurality of fins. The heat exchanger is configured in such a manner that the air-flow resistance of an area facing the outer peripheral side of the fan is larger than the air-flow resistance of an area facing a center portion of the fan.

To provide an input device with improved operability. The input device includes: a display panel that displays a plurality of icons; a trajectory calculating unit that extracts a trajectory of movement of a finger for selecting an icon; a direction estimating unit that estimates a direction in which the finger is going to move, from the trajectory; an image processing unit that rearranges the plurality of icons based on the estimated direction; and a selection detecting unit that detects that an icon is selected by the finger.
摘要:
When user face information and user air-conditioning information are stored in advance via a portable information terminal and a face of a user is located within a face recognition range of an indoor imaging device, an indoor unit of an air-conditioning apparatus recognizes the face. In addition, when it is determined that the face of the user corresponds to the face of a first user represented by first user information stored in advance, the indoor unit of the air-conditioning apparatus blows conditioned air that satisfies a first user air-conditioning environment represented by first user air-conditioning information set for the first user toward the first user.
摘要:
Disclosed is an air conditioner with spatial recognition and detection functions for deciding room shape by determining, based on temperature difference information between the floor and walls occurring during air conditioning operation, a human body detection position log, and a capacity zone of the air conditioner. In an embodiment, an infrared sensor detects a temperature of an area of the room by scanning the area and a control unit acquires thermal image data of the area scanned by the infrared sensor and then calculates a temperature of a wall of the room from the acquired thermal image data. The control unit detects a human body in the room from the thermal image data, calculates a distance between the body and the wall, and calculates a radiation temperature from the wall for the body based on the calculated temperature of the wall and the distance between the body and the wall.
摘要:
Disclosed is an air conditioner with functions for deciding room shape by determining, based on a temperature difference, information between the room's floor and walls occurring during operation, a human body detection position log, and a capacity zone of the air conditioner. In an embodiment, an infrared sensor detects a temperature of an area of the room by scanning the area and a control unit acquires thermal image data of the area scanned by the sensor and then controls the air conditioner based on the thermal image data. The control unit sets a boundary line between a wall and floor of the room at a position on the thermal image data, calculates a temperature difference between vertically adjacent pixels located above and below the boundary, corrects a position of the boundary based on temperature difference, and determines that areas parted by the boundary correspond to the wall and floor, respectively.
