Description

  The present invention relates to an air element cleaning device for an automobile engine that can be cleaned and reused, and more particularly to an air element cleaning device for an engine that reduces the burden of cleaning work by automatic operation. .

  Conventionally, an automobile engine has taken in air from outside the vehicle through an air element. Therefore, it was necessary for the air element to clean the accumulated dirt in accordance with the travel distance of the car or the years of use. Therefore, in this cleaning, an operator sprays compressed air from the tip of the air gun to blow away the dirt adhering to the air element. At this time, the air element is cleaned in the box to prevent an operator from inhaling air containing dust, and dust collected in the box is collected and exhausted.

  An idea of using a waste air element instead of a conventionally used bag filter as a collection filter for dust or the like has been proposed (for example, see Patent Document 1). Thereby, not only the replacement cost of the filter is reduced, but also the disposal cost of the used air element to which dust or the like is attached is suppressed.

Utility Model Registration No. 3136411

  However, the engine air element cleaning device utilizing the above-described conventional concept does not reduce the burden of the air element cleaning operation itself. That is, it is the cleaning operator who thrusts the hand holding the air gun inside the air element in the box and injects the compressed air. Therefore, the dirt accumulated on the back side cannot be removed unless the arm is inserted deep inside the air element. Further, the dirt on the back side of the removed air element may flutter and adhere to the near side again, and the dirt cannot be removed unless the arm is repeatedly put in and out several times.

  In view of environmental problems, resource reuse, and reduction of replacement costs, it is desirable to use the engine air element as many times as possible. Therefore, there is a demand for not only a structure that is free from dirt dust and the like, but also a structure that is safe for the human body, as well as a function that improves the efficiency of cleaning.

  Therefore, an object of the present invention is to provide an air element cleaning device for an engine that automates the air element cleaning operation and reduces the human burden.

  That is, the engine air element cleaning device according to the present invention includes an air injection arm portion in which each of a pair of arm members having air injection ports is provided at a predetermined interval, and a slide portion that slides the air injection arm portion. When the dirty cylindrical air element is cleaned, one of the pair of arm members is positioned inside the air element, and the slide part moves the air injection arm part in the cylinder direction of the air element. It is characterized by sliding.

  Further, it is desirable that each of the pair of arm members is arranged in the vertical direction, and the upper arm member is located inside the air element.

  Further, it is preferable that the slide portion has a rail material and an actuator, and the air jet arm portion slides on the rail material in conjunction with the actuator.

  The actuator is a pneumatic cylinder, and the cylinder body of the pneumatic cylinder is connected to the rail material and the piston is connected to the air injection arm portion, and the air injection arm portion slides on the rail material in conjunction with the piston. It is desirable to do.

  Moreover, it is desirable that the air injection arm portion has an adjuster capable of adjusting a distance between the pair of arm members.

  Each of the pair of arm members is preferably composed of a plurality of arm members having different lengths.

  In addition, it is desirable that the time or order of air injection from the air injection ports of the pair of arm members can be changed.

  Also, an air element cleaning unit having the air injection arm unit, the slide unit, and a roller unit for rotating the air element, and a filtration filter unit for collecting the dirt of the air element removed in the air element cleaning unit An air cleaner having a blower for sucking air mixed with the dirt, an air distributor for distributing air to the air injection arm, a motor for driving the roller, the air distributor, It is desirable to include a control unit having a motor and a control unit that controls driving of the blower.

  In the air element cleaning device for an engine according to the present invention, when the air element is cleaned, the slide portion slides the air injection arm portion, and one of the pair of arm members provided at a predetermined interval is positioned inside the air element. By doing this, not only can the operator automatically perform the same work as cleaning the inside of the air element with an air gun, but the other of the pair of arm members can simultaneously clean the outside of the air element. Can do. Therefore, the air element can be cleaned at low cost and high efficiency.

  Further, among the pair of arm members arranged in the vertical direction, the upper arm member is positioned inside the air element, so that the air element can be cleaned in a stably placed state in the lateral direction. it can.

  Further, the automatic operation of the apparatus can be realized with a simple structure by the air injection arm portion sliding on the rail member in conjunction with the actuator of the slide portion.

  Further, the cylinder body of the pneumatic cylinder as the actuator is connected to the rail material, the piston is connected to the air injection arm part, and the air injection arm part slides on the rail material in conjunction with the piston. Compressed air for cleaning the air element can be used as a drive source for the slide portion.

  In addition, since the distance between the pair of arm members can be adjusted by an adjuster, the air element can be appropriately cleaned according to the size of the air element.

  Each of the pair of arm members is composed of a plurality of arm members having different lengths, so that air can be injected to the air element at a desired pressure.

  In addition, since the time or order of air injection from the air injection ports of the pair of arm members can be changed, the cleaning efficiency can be increased without wastefully injecting compressed air.

  It is also divided into an air element cleaning part with a structure for cleaning the air element, an air cleaner part for sucking dirt of the air element removed by cleaning, and an air element cleaning part and a control device part for controlling the driving of the air cleaner part. Thus, a desired automatic air element cleaning device can be provided.
