複雑となる為、非常に高価な金型費となる。There are few fans that have a boss, hub, blade, and shroud, and the conventional technology with the basic shape is the Utility Model 52-1362.
As described in No. 07, the outer diameter of the hub is the same as the outer diameter of the shroud, and the blade height usually decreases as the outer diameter increases. When producing a molded fan with this shape, the boss, hub, and blade are integrally molded, and the shroud is molded separately and joined using solvent bonding, etc., in order to manufacture the fan with low mold costs. A shroud part was attached to the side of the unit to be matched, and it was used as an alternative to an integrated fan. Alternatively, individual parts are press-formed from sheet metal and assembled using spot welding or the like. However, for all assembly work such as solvent bonding, procedures, tools, materials, and inspections are determined in detail, and even if workers adhere to these standards, there will naturally be variations in the finished product. occurs. In addition, when joining a shroudless fan with an integrally molded boss, hub, and blades to a shroud that is molded separately, there is a drawback that it is difficult to obtain the required dimensional accuracy of the joint surface due to shrinkage due to molding, so the strength of the assembled finished product is reliability is reduced. To prevent this, it is necessary to finish it to the required dimensions by machining. It is a matter of course that this tendency occurs more noticeably as the diameter of the fan becomes larger. If the basic shape was to be integrally molded, the blades would be radially oriented toward the outer diameter from the center, so the mold between multiple blades would be divided into multiple parts for each part, and the molds would be molded sequentially from the outer diameter side. It is necessary to pull it out while moving up and down toward the outer diameter, which results in a complicated mold shape, resulting in very expensive mold costs.
本発明の目的は作業のバラツキによる性能および強度の
バラツキを防止し、性能および強度を低下することなし
に、コストの安いファンを提供することにある。An object of the present invention is to prevent variations in performance and strength due to variations in work, and to provide a fan at low cost without deteriorating performance and strength.

価にできる。By integrally molding the fan, there is no variation in work, and a fan with stable performance and strength can be provided. Additionally, by integrally molding the fan parts, such as the boss, hub, blade, and shroud, joining work is completely eliminated, resulting in lower costs. In addition, by making the outer diameter of the hub smaller than the inner diameter of the shroud and providing a mating surface for the mold in the center of the blade between them, the mold can be the simplest pair of fixed and movable molds, which reduces the mold cost. It can also be done cheaply.

る。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
explain. It has a boss part 1 at the center of rotation that transmits the rotational force from the fan motor, and has a convex cross-sectional shape on the boss 8111 side in order to suppress deformation due to centrifugal force due to rotation, and has an outer diameter smaller than the inner diameter D4 of the Cine Loud 4. It has a structure and dimensional relationship in which a hub 2 having a diameter D2 and a shroud 4 having the outermost diameter of the fan are connected by a plurality of blades 3. The plurality of blades 3 have a line 5 that serves as a mating surface of the mold, and the minimum diameter D4 and maximum diameter D3 of this mating surface, the hub outer diameter D2,
The shroud inner diameter D1 is manufactured according to the following relational expression.

Also, in Figure 1, the movable mold is on the shroud side and the fixed mold is on the hub! The shape of each part is determined so that the shroud part is set in a fixed mold and the hub side is a movable mold, but the above relational expression is the same. be.
