Description

  The present invention relates to an air outlet of a top nozzle and a side nozzle connected to a blower provided in a car wash machine.

  Conventionally, a top nozzle provided in a car wash machine is received by a blower in a casing that has a substantially triangular shape when the blown air is viewed in cross section, and is substantially directed toward the vehicle from a blowout outlet that is converged below the casing. It is configured to blow out uniformly. Therefore, it is conceivable that the top nozzle itself in this car wash machine generates a considerable amount of noise and also generates noise due to vibrations to the vehicle due to wind pressure. Further, as an actual problem, noise is often a problem from various situations such as the environment of today's life, housing circumstances, and local circumstances, and so improvement is urgent.

  The noise generated by the top nozzle as part of the noise generated by the car washer has been taken up as an immediate problem that requires urgent action. The reason is that these car wash machines have recently been installed in areas such as residences and educational districts, and in addition to this, they are open late at night, which adversely affects the living environment in these areas. It has been pointed out. This noise problem is also an unavoidable problem for parties such as stands, and it is indispensable to solve this noise problem in order to improve work and / or the work environment and ensure efficient work. It is a condition.

  In view of the situation as described above, the present invention is not limited to the top nozzle provided in the car wash machine, and is related to the result of searching for noise problems related to the blower installed in this type of car wash machine. If the prior literature is listed, there are the following documents (1) to (3), and an outline thereof will be described.

  This document (1) is a “car wash” disclosed in Japanese Patent Application Laid-Open No. 2004-98802. In the present invention, an air intake port provided at an end portion of the drying nozzle in the longitudinal direction is coupled to the duct hose side, and the flow direction of the air entering the drying nozzle from the duct hose side is along the nozzle axial direction. This is a configuration oriented in the direction, and has a feature that makes it possible to equalize as much as possible the distribution of the amount of air blown from the air outlet in the longitudinal direction of the drying nozzle.

  Reference (2) is “Car Wash Machine” of JP-A-10-236285. The present invention has a configuration in which an inverted triangular top nozzle is combined with an oscillating auxiliary top nozzle in a conventional side view, and a car wash that is nearly perpendicular to the front and rear surfaces, such as a 1BOX car and a wagon car. Even if the vehicle has a surface, there is a feature that water droplets can be reliably removed.

  Further, Document (3) is “Low Noise Blower in Car Wash Machine” disclosed in Japanese Utility Model Publication No. 62-52066. This device is configured to prevent noise by attaching a perforated plate and a sound absorbing material to the inner wall surface of a spiral casing incorporating a blower. However, in this device, if it is judged by common sense, only a part of noise is prevented, and it cannot be considered as a noise preventing device for the entire casing. Therefore, in car wash stations dedicated to cars or gas stations, etc., there is a tendency that houses are built in the vicinity and / or 24 hours business tends to increase, as well as recent environmental maintenance, housing conditions, life When considering the cycle, etc., it is considered urgent to solve the noise problem.
