Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator for ventilating a bathroom or other rooms, for example, and more particularly, to a ventilating fan provided in a fan casing having an intake opening and an exhaust opening. Related to ventilation equipment.

[0002]

2. Description of the Related Art Such a ventilating device is often installed in a limited space such as a space above a ceiling, and after the device is installed, inspection and repair of the ventilation fan for dirt or failure are performed. When performing maintenance work, it is necessary to work by leaning out the upper body from the inspection hole provided in the ceiling, for example,
If the mounting structure of the ventilation fan in the ventilation device is complicated, there is a possibility that such a maintenance operation may be difficult to perform. Therefore, a configuration is adopted in which a member to which the ventilation fan is mounted is detachably inserted.

Therefore, conventionally, for example, Japanese Unexamined Patent Application Publication No.
As disclosed in JP-A-63607, there has been a configuration in which a frame to which a ventilation fan is attached is housed so as to be freely inserted and removed along the inside of a substantially square cylindrical outer cylinder constituting a fan casing. . That is, a pair of sliding contact portions that slidably contact the left and right side walls of the outer cylinder with the plate member to which the ventilation fan is attached, and an engagement formed on the ceiling of the outer cylinder. An engagement portion for inserting and removing while engaging with the guide portion is provided, and an engagement guide portion formed on a ceiling portion of the outer cylindrical body regulates a vertical movement of the plate member; The engagement portion is guided to engage in a state in which the slide movement in the insertion / removal direction is permitted. The sliding contact portion and the engaging portion may be formed by bending a plate member into a U-shape, or by attaching a separate member to the plate member so as to have a substantially U-shape in the insertion / removal direction. Had to be composed. When the frame is stored while sliding along the inside of the outer cylinder, the frame is slid until the frame comes into contact with the end face on the rear side, and the opening on the entrance side of the outer cylinder is closed with the lid. The cover was closed with screws and the lid and the frame were fixed with screws.

[0004]

According to the above-mentioned conventional structure, when the frame is removed and then re-mounted in the maintenance work, the frame is slid until the contact is restricted so that the frame can be properly mounted. Although it can be positioned at the position, the work of inserting and removing the frame body can be easily performed. However, the above-described conventional configuration has the following disadvantages and has room for improvement.

That is, in the above-described conventional configuration, a member (frame) to which the ventilation fan is attached is inserted and removed along the inside of the substantially rectangular outer cylindrical body constituting the fan casing. A configuration for guiding the sliding movement of the frame body inside the outer cylinder body is required, and the external dimensions of the apparatus are increased. Then, for example, when the entire device is installed in a limited narrow space such as a space above the ceiling, or when an operation such as connecting a ventilation duct for intake and exhaust to a fan casing is performed, the space on the outer peripheral side of the device is narrow, There is a disadvantage that such work is difficult to perform.

The present invention has been made in view of such a point, and an object of the present invention is to adopt a rational configuration in the ventilation device having the above-described configuration, and to insert and remove a member for supporting a ventilation fan. This makes it possible to make the external dimensions of the apparatus compact while making it possible to easily perform the operation.

[0007]

According to the characteristic structure of the present invention, the fan casing has a ceiling wall to which the ventilation fan is attached and which can be inserted and removed in the horizontal direction, and a fan casing which is substantially in the insertion and removal direction. And a U-shaped case main body. The ceiling wall is supported on a pair of side walls facing the insertion / removal direction in the case main body, while supporting the load and restricting movement in the lateral width direction. A sliding guide portion that is slidably guided in the insertion / removal direction is provided, and as the ceiling wall slides to an appropriate mounting position, an engaged portion provided on the ceiling wall is attached to the case body. It is configured to restrict the movement of the ceiling wall in the insertion / removal direction by being fitted and engaged downward with the provided engagement portion,
In addition, a switching operation between an operation state in which the movement in the insertion / removal direction is restricted and an upward state by contacting the upper surface of the ceiling wall to restrict the movement, and a release state in which the movement restriction is released. A free switching operation tool is provided.

Therefore, since the ventilation fan is configured to be mounted on the ceiling wall of the fan casing, for example, a member having a ventilation fan mounted on the inner side of a casing that is previously formed in a cylindrical shape as in the conventional configuration is provided. In comparison with the configuration in which the fan is inserted and removed, the entire interior of the fan casing can be used as a ventilation space for ventilation, and there is no extra space for providing a support structure for detachably supporting a member to which the ventilation fan is attached. No space is required, and the external dimensions of the device can be reduced.

When the ceiling wall to which the ventilation fan is attached is inserted into and removed from the case body in the horizontal direction, the ceiling wall is subjected to the load by the sliding guides provided on the pair of side walls of the case body. It is configured to be slid and guided in the insertion / removal direction while being supported and restricted from moving in the lateral width direction. Then, as the ceiling wall slides to the proper mounting position, the engaged portion is engaged with the engagement portion provided on the case body downward, thereby engaging and disengaging the ceiling wall. Will be restricted. In the state where the movement is restricted in this way, the switching operation tool is switched from the release state to the operating state, thereby contacting the upper surface of the ceiling wall and restricting the upward movement. At the attachment position, the position is held in a state where the movement in the insertion / removal direction and the vertical direction is restricted.

Therefore, when the ceiling wall is inserted and removed for maintenance work or the like, if the ceiling wall is moved to the proper mounting position while being slid and guided by the sliding guide portion, the positioning engagement state is established by its own weight in the vertical direction. Therefore, the positioning can be easily performed, and thereafter, the switching operation tool can be maintained at the proper mounting position only by performing the switching operation, so that the insertion / removal operation can be easily performed.

As a result, it has become possible to provide a ventilator which can make the external dimensions of the device smaller while making it easier to insert and remove the ceiling wall as described above.

According to a second aspect of the present invention, in the first aspect, the engaged portion is provided on a flange provided on the ceiling wall so as to face the sliding guide portion. It is formed so as to protrude below the lower edge, and when the ceiling wall is inserted and removed, the flange is slid and guided in a state where movement in the width direction is restricted by the slidable guide, and The projecting lower end portion of the engaged portion is configured to be slid and guided in a state where a load is supported by the sliding guide portion.

Therefore, when the ceiling wall is inserted and removed, the flange portion is slidably guided by the sliding guide portion so that it can be inserted and removed in a state where the movement in the lateral width direction is reliably restricted. Only the protruding lower end of the slide guide is slid while the load is supported by the slide guide, so that, for example, the slide is performed with a smaller contact area compared to the case where the entire flange is slid in contact. As a result, the sliding contact resistance is so small that the sliding operation can be performed easily.

According to a third aspect of the present invention, the switching operation tool is brought into the operation state by switching the contact operation portion to an operation position located on the upper surface side of the ceiling wall, and the switching operation tool is brought into the operation state. The operating portion is configured to be rotatable so as to be in the released state by switching to a non-operating position retracted from the upper surface side of the ceiling wall, and to be in a predetermined rotating range extending between the operating position and the non-operating position. There is provided a rotation restricting tool for restricting a rotation operation range of the switching operation tool.

The switching operation tool can be switched between the operation state and the release state by rotating the contact operation portion between the operation position and the non-operation position. Since the rotation is restricted by the restricting tool to a predetermined rotation range, for example, even when working in a narrow and dim place such as behind a ceiling, the rotation is restricted so that the switching state can be easily checked with a manual feeling. be able to.

According to a fourth aspect of the present invention, in the third aspect, the switching operation tool is provided so as to be freely rotatable around a vertical axis, and when the operating device is operated in the operating state, The formed engaged portion is configured to be held in the operating state by engaging with an engaging portion formed on the upper surface of the ceiling wall.

When the switching operation tool is turned to the operating state, the engaged portion formed thereon engages with the engaging portion formed on the upper surface of the ceiling wall. Even when working in a dimly lit place, it is possible to easily confirm that the working state has been achieved with a manual feeling.

According to the fifth aspect of the present invention, air in the bathroom is taken in through the bathroom intake passage and the intake opening, and air in the other room except the bathroom is taken in through the other room intake passage. Is configured to exhaust the air taken in from each room to the outside through the exhaust opening from the exhaust opening, and simultaneously inhales the air in the bathroom and other rooms other than the bathroom to remove the air taken in from each room. Since the air is exhausted to the outside through the exhaust path, a plurality of rooms can be simultaneously ventilated.
