Disclosed herein is an air conditioner comprising, a housing in which an outlet is formed, a heat exchanger positioned inside the housing, and a fan positioned behind the heat exchanger. The fan configured to blow air to the heat exchanger. And a filter assembly coupled to the housing. The filter assembly configured to filter air entering the fan. The filter assembly covering a rear portion of the fan.

A grille for ventilation apparatus arranged downstream of insufflation elements of a ventilation apparatus, the grille including a grid portion arranged upstream of a stator portion. The insufflation elements may include a fan. The grid portion may include fins which form concentric rings.

A full front blowing type air conditioner is disclosed. The disclosed full front blowing type air conditioner includes a case of which a heat exchanger is disposed in an inner side; and a blower module disposed in rear of the heat exchanger in the case, and configured to discharge a pulse jet for blowing through a front face of the case. The blowing module changes air pressure of a cavity formed between at least one pair of piezoelectric diaphragms and discharges the pulse jet to a side of the heat exchanger according to periodic deformation of the pair of piezoelectric diaphragms to opposite phases to each other.

A power conversion device includes an inverter configured by arms including phase upper-arm switching elements and phase lower-arm switching elements, a power-supply shunt resistor, lower-arm shunt resistors, and a control unit that generates drive signals corresponding to the phase upper-arm switching elements and the phase lower-arm switching elements from detection values of the voltage detectors. The power conversion device changes a ratio of time in which all of the upper-arm switching elements are in an ON state and time in which all of the lower-arm switching elements are in the ON state in one cycle of switching of the inverter according to a modulation ratio.

In an air-conditioning device, back flow is less likely to occur at an outlet port in relation to an inlet resistance, and the air-conditioning device includes: a main body having an inlet port and an outlet port; a cross-flow fan provided inside the main body; and a heat exchanger provided inside the main body, wherein the main body includes at least a front surface, a rear surface, an upper surface and a lower surface, the inlet port is formed in the upper surface, a ratio H/Df between the main body height dimension H and the fan outer diameter Df is 2.2 to 2.7, and an angle of inclination between a rear part of an front upward inclination section of the heat exchanger and a vertical direction is 30° to 45°.

Disclosed are a motor support (1) and a dehumidifier (100) having the same. The motor support (1) includes: a support body (11); and a mounting rack (12) hung below the support body (11) by a connection member (13) and configured to mount a motor.

An air conditioner includes an indoor fan motor driven according to a signal to control the indoor fan motor by a controller, and a controller that resets a reference value of a rated air flow rate according to the pre-set conditions by checking an indoor fan motor driving voltage when an indoor fan motor RPM reaches a reference value of a strong wind mode while the air conditioner operates in strong wind mode. The controller compares the checked indoor fan motor driving voltage with a reference indoor fan motor driving voltage of the rated air flow rate, and resets the reference value when the checked indoor fan motor driving voltage is different from the reference indoor fan motor driving voltage of the rated air flow rate.

A motor assembly includes a motor and sealing member fixed to a frame. The motor includes a stator and a rotor. The stator includes a coil holding portion and a first portion with an annular shape and extending radially outward from the coil holding portion. The rotor includes a magnet and a magnet holding portion located in a first space. The first portion has a first surface in contact with the first space, and a second surface on a side opposite to the first surface. A through hole penetrates from the first surface to the second surface in the first portion. The sealing member is disposed on a side of the stator opposite to the rotor, and is fixed to the frame so a second space between the sealing member and the stator does not communicate with an external space other than the first space.
