Description

  The present invention relates to a small blower for a car wash machine or the like provided for car wash, factory use, or the like.

  A blower installed in a conventional car wash machine, factory, etc., changes the direction of air sucked into the casing from a suction port provided in a spiral casing in a direction of approximately 90 degrees, and then impellers (blade blades). The high-pressure air generated in (1) is discharged (pressed) from the outlet. In this structure, noise often becomes a problem due to various situations such as today's life, environment such as factories, housing conditions, and local circumstances, so it is urgent to solve this noise problem. In addition, due to various circumstances such as today's economic situation, housing situation, or regional situation, the installation area is required to be reduced.

  However, there is a conventional blower of this type, for example, “Low noise blower in a car wash machine” disclosed in Japanese Utility Model Publication No. 62-52066 (referred to as reference (1)). This apparatus has a configuration in which a centrifugal blower is arranged in a casing, the suction port is provided on one surface, and a discharge port for connecting a branch pipe is provided on the other surface (the other surface in a substantially perpendicular direction). Therefore, the air (high-pressure air) exhausted from the blower is suddenly guided to the branch pipe and converged in the branch pipe, which may cause noise generation or cause pressure loss. This causes problems such as a reduction in car wash efficiency. A configuration similar to this is also disclosed in “Car Wash Machine” of JP-A-2004-237932 (referred to as Document (2)).

  And, as a car wash machine that the present invention intends next, it is intended to reduce the size of the moving car wash machine body, reduce the installation area of this type of car wash machine, or save resources such as power consumption. However, there was no car wash machine that could meet these demands in the market. Therefore, the present invention devisees the positional relationship between the air inlet and the air outlet of the blower to reduce the size of the car wash machine body. Prior art that can reduce the size of a blower related to the intent of the present invention is an “air conditioner” disclosed in Japanese Patent Laid-Open No. 7-190415 (referred to as reference (3)). This invention is a configuration in which the blower of the indoor unit is horizontally arranged, and the duct is correspondingly formed in a rectangular shape and integrally formed with foam heat insulating material, and by adopting the horizontal arrangement of this blower and the rectangularization of the duct, It is possible to provide a whole-building air conditioning system that is superior in size, thickness, installation, and workability.

Japanese Utility Model Sho 62-52066 JP 2004-237932 A JP 7-190415 A
