A helically wound hollow membrane module having a core with a plurality of helically wound layers of semi-permeable hollow fibers wound on the core. The fiber wind angle with respect to any one layer of fibers may be essentially constant along the axial length of the module, except in one or both end or tubesheet regions, where the wind angle may be increased, in at least some of the layers relative to the essentially constant wind angle, to produce an area of decreasing diameter.

The invention discloses an electric fan and an air outlet structure. The air outlet structure comprises a drive device, a plurality of wind shields and a linkage mechanism connected with the drive device and the wind shields. The wind shields are driven by the drive device to sequentially move through the linkage mechanism. As the structure is adopted, the wind shields can be made to move in sequence through the linkage mechanism, accordingly the air outlet angle is adjusted through the opening degree of the wind shields, and the air outlet angle is increased. The defect that when a conventional electric fan in the prior art steers, a wind field is instable is overcome, the electric fan can output air stably and conveniently with a large angle, and people feel comfortable. The beneficial effects of being simple in structure and low in cost are achieved.

The invention provides an air conditioner indoor unit. The air conditioner indoor unit comprises a shell, a first air guide plate and a second air guide plate. An air outlet facing the front downwardsis formed in the shell. The first air guide plate and the second air guide plate are installed on the front side and the lower side of the air outlet in a rotating mode respectively to cooperativelyopen and close the air outlet, and the second air guide plate is configured into a front air guide state when the second air guide plate can rotate to the lower side of the air outlet and make the airguide surface of the second air guide plate face upwards so as to lead the air feeding flow forwards or front upwards or front downwards; and a lower air guide state when the second air guide plate can rotate to the rear side of the first air guide plate and make the air guide surface face backwards so as to lead the air feeding low downwards. The air conditioner indoor unit can achieve cold airrising blowing and hot air sinking blowing.

The invention discloses an air conditioner indoor unit. The air-conditioning indoor unit of the present invention includes fan blades, a vortex and a tongue, an air outlet formed between the vortex and the tongue, the air outlet includes a first outlet section and a second outlet section, the An air guiding device is arranged in the second outlet section. The invention increases the area of ​​the air outlet of the air conditioner, expands the air outlet angle of the air conditioner at the same time, and improves the use comfort of the air conditioner.

An air guide structure and a fan having same. The air guide structure comprises a frame (1) and multiple air guide plates (2) disposed in the frame (1). The two ends of each air guide plate (2) in the length direction thereof are connected to the frame (1). The end of at least one air guide plate (2) in the width direction thereof is provided with a bent portion (3) bent in the air incoming direction.

The invention discloses a wall-mounted type air conditioner indoor unit. The wall-mounted type air conditioner indoor unit comprises a shell; an air outlet is formed in the front lower portion of the shell; side air inlets are formed in the side faces of the shell; heat exchangers corresponding to the side air inlets are formed inside the shell; a rear air inlet is formed in the rear lower portion of the shell; an air supplying device is formed inside the shell; a volute and a centrifugal fan located inside the volute are formed inside the shell and above the air supplying device; the air outlet portion of the volute faces towards hot exchange air flues in the air supplying device and is provided with an annular surrounding part extending towards the air supplying device and annularly surrounding the hot exchange air flues; mixed air cavities are formed between the annular surrounding part and the hot exchange air flues; a diversion assembly used for adjusting the air outlet angle of the air outlet portion is formed between the air outlet portion of the volute and the air supplying device. By the application of the wall-mounted type air conditioner indoor unit, adjustment of the air supplying angle of the wall-mounted type indoor unit used for supplying soft mixed air with the proper temperature can be achieved.

The present invention provides an air-conditioning indoor unit, which includes a shell, which is provided with an air outlet facing forward and downward; and the deflector includes a deflector body and a diverter, the diverter is arranged on the deflector surface of the deflector body, and is configured to guide the air supply flow passing through it gradually away from the deflector body Flow; the wind deflector includes the wind deflector body and the wind-raising part, the wind-lifting part is arranged on the wind-guiding surface of the wind-deflecting plate body, and is configured as a front guide where the wind-deflecting plate is on the lower side of the air outlet and the wind-guiding surface faces upwards. When the wind is in the state, the air supply air flowing through it is guided to flow away from the main body of the air deflector gradually. The air-conditioning indoor unit of the present invention can realize better effects of upward blowing of cold wind and downward blowing of hot air.

The invention relates to the technical field of fans, in particular to an air guide structure and a fan. The air guide structure comprises a frame body, the frame body is arranged below an air outlet grille, and an air outlet flow channel is formed in the frame body; in the radial direction of the air outlet flow channel, a plurality of flow deflectors are rotatably arranged in the frame body at intervals; and the flow deflector has a first state of closing the air outlet flow channel and a second state of opening the air outlet flow channel under the driving of external force. According to the air guide structure and the fan, the flow deflectors are arranged below the air outlet grille and can rotate in an air outlet duct, when the fan does not work, the flow deflectors rotate, the multiple flow deflectors are spliced, an annular air duct is closed, and therefore dust is prevented from entering the air outlet duct through an air outlet of the air outlet grille, and use of the fan and the like is prevented from being affected.

The present invention provides an air conditioner indoor unit and an air conditioner. The air conditioner indoor unit is suspended and installed at a corner of the room, and the air conditioner indoor unit includes a panel (2) and an air outlet (20). The panel (2) is In the structure of the arc surface, the air outlet (20) is arranged on the panel and is formed as an arc air outlet. According to the present invention, a large wide-angle air outlet can be effectively formed, the air outlet area is larger than the existing plane structure, the air outlet range is effectively increased, the air outlet coverage is effectively increased, and the indoor comfort is effectively improved, which is both beautiful and user-friendly Bring a good experience, adopt the wall-mounted corner installation method, which saves space and is beautiful.
