TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pipe cover device, in which an insertion passage such as electric wires and pipes for connecting an indoor unit and an outdoor unit of an air conditioner and an air flow passage for circulating air inside and outside the room are provided, and an electric wire and a pipe are provided. It is intended to cover and protect the bent portion, and to easily and surely clean the insect net or the like from the outside.
[0002]
[Prior art]
Conventionally, in order to store and protect drainage drain pipes from indoor units of air conditioners, refrigerant pipes connecting indoor units and outdoor units, electric wires, and the like, various types of synthetic resin are used. There was a pipe cover of the shape.
Conventionally, the pipe cover has an insertion passage for wires and pipes connecting the indoor unit and the outdoor unit of the air conditioner and an air flow passage for circulating air inside and outside the room, and a through hole provided in the wall. A pipe cover body that covers and protects a bent portion of an electric wire or a pipe that connects one end to an opening of the pipe and connects the other end to another pipe cover along the wall from the opening to connect. There is a piping cover device (for example, see Patent Document 1).
[0003]
[Patent Document 1]
Japanese Patent No. 3280579
[Problems to be solved by the invention]
However, the conventional pipe cover device described in Patent Literature 1 has a pipe cover main body that includes an insertion passage such as an electric wire or a pipe connecting an indoor unit and an outdoor unit and the like and an air flow passage that circulates indoor and outdoor air. For supplying and discharging air from the air flow passage to the outside of the pipe cover, at a position opposite to the opening of the pipe cover body, one end of which is communicated and connected to the opening of the through hole provided in the wall. A vent provided with an insect screen for preventing insects from entering is provided, and a corner of the pipe cover is covered by a hood-shaped weather cover.
[0005]
Therefore, when the insect screen provided with the ventilation hole provided in the pipe cover body is clogged with dirt or the like or is dirty, when the insect screen is cleaned, the insect screen is cleaned by directly washing with water from the outside. There is a structural limitation that the insect screen cannot be cleaned unless the weather cover is removed from the pipe cover body. Therefore, cleaning the insect screen takes a lot of time and effort, and is troublesome. In addition, when the insect screen breaks, it is necessary to remove the weather cover from the pipe cover body for maintenance and management such as replacing it with a new one or repairing it. And it took a lot of time and effort to work.
[0006]
In addition, when the conventional pipe cover device described in Patent Literature 1 is connected to a pipe cover that extends horizontally or diagonally due to the arrangement of the outdoor unit, the opening of the weather cover opens laterally, so that rain or snow falls. In this case, there is a disadvantage that rain and snow easily enter the room through an air flow passage communicating with the inside of the pipe cover through the air vent portion.
[0007]
The present invention solves the above-mentioned conventional drawbacks, and can easily and reliably perform cleaning when the insect repellent net is clogged or soiled from the outside while being attached without removing the vent cover from the pipe cover body, In addition, it can be performed without much time and effort, and maintenance and management such as replacement with a new insect repellent net can be performed easily and reliably, and rain and snow can be passed through the air flow passage provided in the pipe cover body. An object of the present invention is to provide a pipe cover device which is hard to enter a room, has sufficient waterproof performance, is excellent in soundproofing, and is simple in structure and inexpensive in manufacturing cost.
[0008]
[Means for Solving the Problems]
The present invention solves the above-mentioned conventional inconvenience, and the invention described in claim 1 is directed to an air passage that allows indoor and outdoor air to flow through insertion passages such as electric wires and pipes that connect an indoor unit and an outdoor unit of an air conditioner. A flow passage is provided inside, and one end is connected to and connected to an opening of a through hole provided in a wall, and the other end is connected to another pipe cover along the wall from the opening to connect thereto. In a pipe cover device provided with a pipe cover main body that covers and protects a bent portion, a ventilation port that supplies and exhausts air in the air flow passage to the outside is provided at a position corresponding to the opening, and the ventilation port is covered. Means was adopted in which a vent cover extending in the vertical direction was provided, and an insect net was provided at the lower end of the vent cover to prevent insects from entering.
[0009]
According to a second aspect of the present invention, in the first aspect, a plurality of attachment portions are provided on an inner peripheral edge of the opening facing the opening of the pipe cover main body, and the vent cover covers the opening. A mounting portion that is removably mounted on the mounted portion so that a mounting position can be changed in accordance with an installation direction of the pipe cover body in which electric wires and pipes are routed on an inner circumference of the mounting tube portion. Is adopted.
