Abstract: A rear panel assembly includes a rear panel body provided with a vent and a motor bracket arranged at a side of the rear panel body and connected to the rear panel body. The motor bracket is at least partially opposite to the vent, and the motor bracket is provided with an air hole to allow air to flow into the vent through the air hole.

Abstract: A heat exchanger includes a fin set formed by a plurality of fins stacked together and a refrigerant pipe set passing through the fin set. The fin set includes a connection member, and a first fin member and a second fin member connected to each other via the connection member. An included angle between the first fin member and the second fin member is larger than zero. The first fin member and the second fin member are arranged at two sides, respectively, of a notch of the fin set. The notch is located at an air input side and/or an air output side of the connection member.

Abstract: A method for controlling an air conditioner includes, after the air conditioner is turned on, controlling an indoor ambient temperature sensor, an indoor heat exchanger temperature sensor, an outdoor heat exchanger temperature sensor, an outdoor ambient temperature sensor, and an exhaust gas temperature sensor to determine an indoor ambient temperature, an indoor heat exchanger temperature, an outdoor heat exchanger temperature, an outdoor ambient temperature, and an exhaust gas temperature, respectively, determining a first, second, third, fourth, and fifth compressor frequencies based on the indoor ambient temperature, the indoor heat exchanger temperature, the outdoor heat exchanger temperature, the outdoor ambient temperature, and the exhaust gas temperature, respectively, determining a minimum compressor frequency based on the first, second, third, fourth, and fifth compressor frequencies, and controlling a compressor of the air conditioner to operate at the minimum compressor frequency.

Abstract: A panel assembly for an air conditioner includes a face frame and an air inlet panel. The face frame includes an air inlet and an air outlet located above the air inlet. An air outlet surface of the air outlet extends obliquely backward in a direction from bottom to top. The air outlet surface is a plane on which an end surface of the air outlet is located. The air inlet panel is provided at the air inlet.

Abstract: A window air conditioner includes a casing including a receiving groove formed at an outer peripheral wall of the casing. The receiving groove has an open top, an open left side, and an open right side. The casing is divided into an indoor part and an outdoor part by the receiving groove. The window air conditioner further includes an indoor heat exchanger and an indoor fan arranged in the indoor part, and an outdoor heat exchanger and an outdoor fan arranged in the outdoor part.

Abstract: A window air conditioner includes a casing including a cabinet. The cabinet includes a receiving groove formed at an outer peripheral wall of the cabinet. The receiving groove is recessed downwards to separate the cabinet into an indoor part and an outdoor part. The window air conditioner further includes an indoor heat exchanger and an indoor fan arranged in the indoor part, and an outdoor heat exchanger and a compressor arranged in the outdoor part.

Abstract: A window air conditioner includes a casing including an indoor portion and an outdoor portion, an indoor fan wheel arranged in the indoor portion, and an indoor heat exchanger arranged in the indoor portion. The indoor portion includes an air inlet and an air outlet. The indoor heat exchanger includes a first heat exchange portion extending vertically and a second heat exchange portion connected to the first heat exchange portion and extending obliquely towards the indoor fan wheel.

Abstract: A window air conditioner includes a casing and a positioning device. The casing includes a cabinet including an outdoor part and an indoor part spaced apart from each other to form a receiving groove. The positioning device has a locked state and an unlocked state, and is configured to extend further into the receiving groove in the locked state than in the unlocked state.

Abstract: A window air conditioner includes a casing and a positioning member provided at the casing and configured to be switchable between a storage state and a working state. In the storage state, the positioning member is stored at the casing. In the working state, the positioning member is at least partially outside the casing for connecting and positioning the casing with a window frame.

Abstract: A chassis for a window air conditioner includes an indoor part and an outdoor part arranged along a length direction of the chassis. The indoor part includes an air inlet hole at a bottom wall of the indoor part. The air inlet hole penetrates the chassis in a thickness direction of the indoor part.

Abstract: A water receiving tray for a window air conditioner includes a tray body and a wiring body. The tray body includes a water tank. The wiring body is provided at a side of the tray body proximal to an outdoor part of the window air conditioner. The wiring body includes a wiring groove.

Abstract: A window air conditioner includes a housing including a separation groove dividing the housing into two parts, a mounting base movably mounted in the separation groove, and a sealing member connected with the mounting base. The sealing member is fitted with the mounting base by deformation, and the sealing member is configured to be driven by the mounting base to switch between a storage state and a working state. In the storage state, the sealing member is received in the separation groove. In the working state, the sealing member is at least partially outside the separation groove.

Abstract: A window air conditioner includes a housing including an outdoor portion and an indoor portion spaced apart from each other to form an accommodation groove, and a seal assembly including a rotary mounting base fixed at the housing, a fixation member rotatably connected with the rotary mounting base and configured to rotate out of the accommodation groove, and a seal mating member coupled to the fixation member and configured to rotate out of the accommodation groove when the fixation member rotates out of the accommodation groove.
