As the preferred scheme of one, as shown in Figure 2, for the ease of manufacturing and installing, spiral case 84 comprises spiral case cover 841 and spiral case base plate 842, spiral case cover 841 is formed as becoming large tubular relative to the radius of electrical axis along the sense of rotation of impeller 83, the outer rim having a sidewall for mounted motor 81 and be located at sidewall surrounds the perisporium of impeller, preferred described perisporium and described sidewall one-body molded, spiral case cover 841 is open design at the opposite side relative with the side of mounted motor 81, is conducive to mounted motor 81 and impeller 83 like this.Spiral case base plate 842 is for closing the side opened wide of spiral case cover 841 at opposite side, spiral case base plate 842 is provided with intake grill as aforesaid spiral case intake grill, spiral case cover 841 is connected with spiral case base plate 842 in the side away from motor 81, and making the intake grill of impeller 83 relative with the intake grill of spiral case base plate 842, the concrete structure of impeller 83 is with the blade wheel structure in embodiment two.When spiral case blower fan described in embodiment two is installed on mounting plate (not shown), usually the opposition side of side of being connected with spiral case cover 841 by spiral case base plate 842 is connected with mounting plate, mounting plate is provided with mounting plate intake grill, and the intake grill of spiral case base plate 842 is relative with mounting plate intake grill.When needs overhaul motor or impeller or change, only need by spiral case cover 842 together with motor 81 and impeller 83 one disassemble, do not need to remove spiral case base plate 842, do not need to remove mounting plate 82 yet, improve dismounting convenience and the maintainability of spiral case blower fan.
Because spiral case adopts plastic materials to make usually, bulk strength is not high, directly being installed to by motor 81 on spiral case 84 to cause the strength deficiency of spiral case 84 cause spiral case to be out of shape with the power of support motor or damage, for this reason, preferably, also can supporting disk be set, supporting disk is made up of metallic material, and motor 81 is installed on supporting disk, and supporting disk is connected with spiral case 84 again, the power of motor is directly born by supporting disk, can reduce the load of spiral case.
In embodiment two, also have the first sealing configuration as described in embodiment one, the first vibration damping structure or the second vibration damping structure or its combination, the first half shells 13 of concrete structure in spiral case cover 841 alternative embodiment one, are no longer described in detail.
Below the concrete assembling mode of the mounting structure of the spiral case blower fan of embodiment two is described in detail:
When spiral case blower fan is fixed on mounting plate 82, comprising:
S1, motor 81 to be fixedly connected with spiral case 84;
S2, impeller 83 to be connected with motor 81;
S3, spiral case 84 is installed to mounting plate 82 together with motor 81 and impeller 83 one, wherein, described mounting plate is provided with intake grill, and the intake grill of described spiral case is relative with the intake grill of described mounting plate.
Compare existing spiral case fan installing structure, the motor 81 of the spiral case blower fan in the mounting structure of embodiment two, impeller 83 are all arranged on spiral case 84, and during installation and spiral case 84 integral installation, it is more convenient to install.When needs motor 81 or impeller 83 overhauled, safeguard, the operation such as replacing time, only spiral case 84 need be disassembled from mounting plate 82 together with motor 81, impeller 83 entirety.Do not need to remove and install plate 82, overall maintainability is better.In addition, it should be understood by one skilled in the art that the accompanying drawing provided at this is all for illustrative purposes, and accompanying drawing is not necessarily drawn in proportion.
