Embodiment 1

[0029] Refer to attached figure 1 , 2 . The present invention includes a housing 101, a motor 102, a centrifugal fan wheel 103 and an air discharge channel 104 thereof. The plane shape of the housing is approximately fan-shaped, and its fan-shaped angle is adapted to the corner of the wall where it is installed. It is also provided with a wall-mounted connector 105 , The wall-mounted connector is provided on the side wall 106 of the housing forming the fan-shaped corner, and the side wall of the housing forming the fan-shaped corner is provided with an air outlet 107 matched with the air exhaust duct. Reference numeral 108 is a panel with an air grid.

[0030] The plane shape of the housing side wall 10 can be arc-shaped as shown in the figure, or a broken-line shape composed of several straight lines, or a mixed line shape composed of several straight lines and arcs, which are all included in In the concept of "the plane shape is approximately fan-shaped".

Embodiment 2

[0032] With reference to accompanying drawing 3,4,5. In addition to the structure of Embodiment 1, this embodiment also has another air outlet 209 , that is, the side wall 206 of the housing forming a fan-shaped corner is provided with two air outlets with different air outlet directions. Reference numeral 201 is a casing, 202 is a motor, 203 is a centrifugal wind wheel, 204 is an exhaust duct, 205 is a wall-mounted connector, 207 is an air outlet, and 208 is a panel with an air grid. No matter the ventilating fan of producing air outlet 209 directions or 207 directions like this, housing can be shared, only need only change to set up corresponding air exhaust device, and make air outlet and air exhaust duct cooperate and get final product.

[0033] As a further structure of this embodiment, the air exhaust channel uses a housing as its top plate, and the bottom plate 210 of the air exhaust channel is detachably connected to the side wall. In this way, the side wall and botto...

Embodiment 3

[0035] Refer to attached Image 6 , 7 . In this embodiment, except the structure of Embodiment 2, the two air outlets 307, 309 both have connecting air ducts 311 connected thereto. Reference numeral 301 is a housing, 302 is a motor, 303 is a centrifugal fan, 304 is an exhaust duct, 305 is a wall-mounted connector, 306 is a side wall of the housing forming a fan-shaped angle, 307 is an air outlet, and 308 is a wind belt. grid panel. Like this, the present invention has possessed the functional base of two-way selection air outlet, and its motor can adopt two-way motor, also can adopt one-way motor and change and the forward and reverse connection method of power supply when reversing, and its wind wheel can adopt two-way wind Wheel, also can adopt unidirectional wind wheel and choose the wind wheel of opposite direction when reversing.

[0036] Both the exhaust duct and the connecting air duct use the housing as the top plate, and the bottom plate 310 of the exhaust duct an...

Abstract

The household centrifugal scavenger fan includes casing, motor, centrifugal wheel and its wind exhaust channel, the casing is fan-shaped plane to suit wall corner and has wall connecting part and wind outlet to match with the wind exhaust channel. The said fan is suitable for suitable for use in household and has low installation cost and suitable for installation in wall corner and this will notaffect the configuration of other household appliance and furniture.

Description

technical field [0001] The invention relates to a centrifugal ventilation fan. Background technique [0002] There are two types of ventilation fans, one is the blade type axial flow ventilation fan, and the other is the centrifugal wind wheel ventilation fan. The former has low ventilation pressure and is not suitable for use in high-floor rooms. The latter has high ventilation pressure and is suitable for use in high-floor living rooms. However, at present, this type of ventilation fan is installed in the ceiling, and the living room must first be equipped with a ceiling before it can be installed. Therefore, the installation cost is high, disassembly and assembly are inconvenient, and it affects the living space of the living room. net height. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a household centrifugal fan that can overcome the above defects. For this ...
