2. Description of the Related Art It is generally known that an aluminum horizontal blade is used as a horizontal blade provided at an air outlet of an air conditioner body for changing a wind direction. When this type of aluminum horizontal blade is used, secondary processing such as flocking is required on the surface of the horizontal blade in order to prevent dew condensation, so that there is a problem that the manufacturing cost of the horizontal blade increases. In order to solve this problem, it has been proposed to use a resin horizontal blade manufactured by injection molding as a horizontal direction blade provided at an air outlet of an air conditioner body.

[0003]

However, when resin horizontal blades are used for the air outlet of the air conditioner main body, since these horizontal blades are conventionally manufactured integrally by injection molding, they are connected to the air outlet of the air conditioner main body. If several types of horizontal blades having a desired desired length are manufactured, there is a problem in that the die manufacturing cost corresponding to several types increases and the manufacturing cost of the horizontal blades increases.

An object of the present invention is to provide a wind direction changing device for an air conditioner and a method for manufacturing the same, which solves the above-mentioned problems of the prior art and reduces costs.

It is characterized by being welded by ultrasonic welding.

According to a second aspect of the present invention, in the first aspect, a positioning groove extending in a longitudinal direction is provided on a support surface of the horizontal blade main body, and a positioning protrusion fitted to the positioning groove is provided on the support member. It is characterized by having.

According to a third aspect of the present invention, a resin-made horizontal blade material is formed by extrusion molding, and this resin-made horizontal blade material is cut into a desired length that fits into an air outlet of an air conditioner body. A manufacturing method characterized in that a horizontal blade main body is formed, and a support member is welded to the support surface of the horizontal blade main body by ultrasonic welding.

According to the invention, first, a resin horizontal blade material is manufactured by extrusion molding, and then the horizontal blade material is cut into a desired length suitable for the air outlet of the air conditioner body. According to this, it is not necessary to prepare in advance a plurality of types of horizontal blades having a length suitable for the air outlet of the air conditioner body, so that the manufacturing control of the horizontal blades becomes easy, and the manufacturing of the horizontal blades is performed by injection molding. Therefore, a plurality of types of molds are not required as in the related art, and the mold manufacturing cost is greatly reduced. Next, since the support member is welded to the support surface of the horizontal blade body by ultrasonic welding, the support member is firmly fixed and can be fixed at an arbitrary position, so that the degree of freedom in horizontal blade design is improved. For example, if a positioning groove is formed in the horizontal blade main body, the support member can be fixed at an accurate position of the horizontal blade main body only by fitting the projection of the support member into the positioning groove.
