Description

  The present invention relates to a control panel air filter cleaning device.

  When a fan for cooling storage components is attached to the control panel, an intake opening for taking in outside air is required, and a filter must be provided to prevent intrusion of dust from the opening. When the control panel is in operation, the air filter is clogged with dust, which lowers the intake efficiency. Therefore, it is necessary to remove the dust by regular maintenance. As a maintenance, the cleaned air filter can be continuously used by washing with water or sucking out dust with a vacuum cleaner and removing the clogged dust.

However, since the air filter is handled as a consumable part, it is cleaned several times during maintenance and inspection by the manufacturer, and finally discarded by replacement. The customer rarely cleans the filter frequently, and the situation is that dirt is accumulated in the filter until the maintenance and inspection by the manufacturer.
However, if the air filter is not cleaned for a long period of time, the amount of air intake by the cooling fan will be reduced and the cooling effect will be reduced, so the electrical / electronic parts and mechanical parts in the control panel will generate heat and cause malfunction. The service life of parts is shortened.

  As an example of conventional technology related to maintenance of an air filter for a control panel, Patent Document 1 discloses a panel for ventilation by preventing rainwater from entering a cabinet such as a switchboard or control panel installed outdoors. A ventilation device is disclosed.

Japanese Patent No. 4730870

  The panel ventilation device described in Patent Document 1 describes the filter replacement operation, but does not mention prevention of contamination of the filter itself.

  An object of the present invention is to remove and clean dust adhering to an air filter of a control panel.

  The present invention is a control panel air filter cleaning device, which is installed in a control panel and operates in accordance with opening and closing of the door of the control panel, and is disposed in the vicinity of the air filter, and is one end of the link mechanism. And a cleaning device for the control panel air filter, wherein the dust is adhered to the surface of the air filter by the cleaning brush in conjunction with the opening / closing operation of the door. be able to.

  According to the present invention, since the control panel air filter cleaning device uses the force of opening and closing the door, it does not require a power source for operation and can be realized with an inexpensive structure. In addition, frequent cleaning improves the cooling performance in the control panel, reduces malfunctions due to heat generation, and extends the life of components.

It is the front view and side view which show the external appearance of the control panel which concerns on one Example. It is a perspective view which shows the cleaning apparatus of the control panel air filter which concerns on one Example. It is a figure which shows the components structure of the cleaning apparatus of the control panel air filter which concerns on one Example.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an external view of a control panel 10 according to the present embodiment. Reference numeral 15 denotes a handle of the control panel, 17 denotes a slit group for intake, and 20 denotes a cooling fan. The cooling air sucked from the slit group 17 is exhausted from the ceiling.

  FIG. 2 is a perspective view of the cleaning device for the control panel air filter according to the present embodiment, and FIG. 3 is a diagram showing a component configuration of the cleaning device. Based on FIG. 2 and FIG. 3, the structure of this cleaning apparatus is first demonstrated below. In FIG. 2, 13 is a door of the control panel 10, 13a is the back surface of the door 13, 110 is attached to the back surface 13a of the door 13, and has a slide frame (details will be described later) having a long guide groove 150 in the horizontal direction. Reference numeral 100 denotes an air filter, and reference numeral 90 denotes a presser net that holds the air filter 100. Reference numeral 60 denotes a guide portion having a horizontally long groove that guides the movement of the first link 40 and the second link 70, and 30 denotes a first guide that is installed on the bottom surface of the control panel 10 and can rotate around its own axis. One rotation pin.

  Reference numeral 50 denotes a slide pin that can rotate about its own axis and slides in a loosely fitted state in the long groove of the guide portion 60, and connects and supports one end of the first link 40 and one end of the second link 70. Yes. Reference numeral 80 denotes a fulcrum of the second link that can rotate around its own axis installed on the back surface 13 a of the door 13. Reference numeral 140 denotes a second rotating pin that can rotate about its own axis, and loosely fits into the elongated hole 84 of the second link to slide in the elongated hole. Reference numeral 40 denotes a first link having one end supported by the first rotation pin 30 and the other end supported by the slide pin 50. Reference numeral 70 denotes a second link having one end supported by the slide pin 50 and the other end supported by the second rotation pin 140.

  Reference numeral 120 denotes a cleaning brush that removes dust from the air filter 100, and reference numeral 130 denotes a slide piece that slides left and right in the guide groove 150 of the slide frame 110. The slide piece 130 is loosely fitted to the second rotation pin 140 with the cleaning brush 120 mounted. The second link 70, the second rotation pin 140, the slide piece 130, and the cleaning brush 120 are positioned between the air filter 100 and the slide frame 110 in the assembled state.

  Next, the operation of the cleaning device will be described below. As the door 13 is opened and closed, the slide pin 50 is pushed or pulled by the first link 40, and thus moves to the left and right in the guide portion 60 as indicated by the arrow 55. In a state where the door 13 is closed, the slide pin 50 is located at the rightmost position in the guide portion 60. As the door 13 is opened, the slide pin 50 is pulled to the left by the first link 40. However, when the door 13 is in the most open state, it is located on the leftmost side. In conjunction with the movement of the first link 40, the second link 70 rotates around the fulcrum 80, and accordingly, the slide piece 130 moves in the guide groove 150 left and right. Along with this, the cleaning brush 120 moves left and right, and the dust can be removed by rubbing the surface of the air filter 100 left and right.

  According to the present embodiment, since the door is manually opened and closed, an operation power source is not required, and an inexpensive structure can be realized. In addition, frequent cleaning of the filter improves the cooling performance in the control panel, reduces malfunction due to heat generation, and extends the life of parts.
