Description

[Detailed description of the invention] This invention relates to an underfloor air intake machine that cools the room by taking in cold air from under the floor into the room.

The underfloor air intake machine (underfloor cooling fan) consists of a motor with a fan, a support arm that supports the motor,
It consists of a patch plate that blows and diffuses cold air, and is installed under the floor as shown in Figure 1. In Fig. 1, 1 is a motor with a fan 2, 3 is a support arm,
4 is a mounting board, 5 is a fixed backing plate, 6 is a louver,
7 is the floor surface. Then, by rotating the fan 2, the cooled air under the floor is sucked in from the air passage 8, raised, and applied to the fixed batting plate 5 located above the passageway opening 8a, from between the batting plate 5 and the mounting board 4 into the room. It is blown out like an arrow. In this case, the backing plate 5 is located above the fan 2,
To prevent a person from accidentally putting his or her foot into a fan 2. However, this fixed backing plate 5 becomes a hindrance when the underfloor air intake machine (hereinafter abbreviated as "air intake machine") is not in use.

This invention was developed in view of the above circumstances, and includes a passageway through which air passes from under the floor to above the floor, and a fan facing above the floor. This is an air intake machine that is equipped with a patch plate that allows the air sent through the air to hit and diffuse. The gist is the air intake machine, which is a feature of the system.

That is, when this air intake device is not in use, the backing plate acts as a cover for the passage opening, so it does not get in the way.

Next, this invention will be explained based on examples.

FIG. 2 is a partially cutaway perspective view of an embodiment of this invention. That is, this air intake machine has a backing plate 1
Attach four rod-shaped legs 11 to the mounting board 12 and cut the passage opening edge 13 of the mounting board 12 to match the dimensions of the backing plate 10 to create a storage section, and attach four legs 11 corresponding to the four legs 11 to the mounting board 12. A bottomed hole 14 and four through holes 15 are provided, and when the air intake machine is used, the leg 11 of the backing plate 10 is inserted into the bottomed hole 1 as shown in FIG.
4 and position the backing plate 10 above the passageway opening (standing up state), and when not in use, pull the handle 16 and insert the leg 11 of the backing plate 10 into the bottomed hole 14.
After pulling it out, it is inserted into the through hole 15, and the cover plate 10 is lowered and stored in the storage part as shown in FIG. 3, so that it serves as a cover for the passageway opening. Further, a limit switch 17 is provided on the back side of the passage opening edge 13, and when the cover plate 10 is stored in the storage section, the push button contacts the lower surface of the cover plate 10, and the power to the motor 1 is turned off. It is becoming like this. Moreover, since the bottomed hole 14 is a counterbore hole, when the backing plate 10 is positioned above the passage 8, the legs 11 are prevented from wobbling and moving. A fan 2 is attached to the motor 1. This fan 2 is arranged in a passageway 8, facing under the floor and facing a backing plate 10. In Figure 2, 1
8 is a wire mesh, 19 is a switch, and 20 is a control box. The other parts are the same as those in FIG.

As shown in FIG. 2, in this air intake machine, when the leg 11 of the backing plate 10 is in an upright position and the fan 2 is rotated by the motor 1, the fan 2 is inserted from under the floor. The cold air thus sent hits the patch plate 10, then blows out laterally from between the patch plate 10 and the passageway opening edge 13, and diffuses. Since the fan 2 faces the upper side of the floor and faces the backing plate 10, the cold air blows onto the backing plate 1.
0 is strongly applied, and the cold air is efficiently diffused.

Since this air intake machine is configured as described above, when the patch plate 10 is not in use, the patch plate 10
is stored in the storage section, and its top surface is flush with the floor surface. Therefore, it does not get in the way. Further, when the air intake machine is used, the backing plate 10 stands up from the floor surface, so it can be used as a storage stand.

FIG. 4 is a partially cutaway perspective view of the main part of another embodiment;
FIG. 5 is a sectional view taken along line A-A'. That is,
This air intake machine has a disc 21 attached to the lower end of the leg 11 of the backing plate 10, and a passage opening edge 13.
The top edge is concave and there is a pitfall 2 at the bottom edge.
A long groove 22 having a diameter of 2a is provided, and the disc 21 is loosely fitted into the long groove 22, and the disc 21 and the tapered part 23 at the upper end of the long groove 22 prevent the leg 11 of the backing plate 10 from coming off. When the plate 10 is turned clockwise, the backing plate 10 is held in an upright position, and when the plate 10 is turned in the opposite direction, the disc 21 is held in the pit hole 22 at the bottom of the long groove 22.
a and the cover plate 10 is lowered to cover the passageway opening. The other parts are the same as the embodiment shown in FIG.

As a result of this configuration, the leg 11 of the patch plate 10 may come out of the hole during use of the air intake machine, causing the patch plate 10 to
This will prevent the person from falling over.

FIG. 6 is a block diagram of still another embodiment. That is, in this air intake machine, a water filter device 31 that can create a cylindrical water filter is arranged in the air passage, and air under the floor is taken in from the entire circumference of the cylindrical water filter created by the device. After cooling and removing dust, fan 2 sends it into the room. As shown in FIG. 7, this water filter device 31 consists of a ring-shaped water sprinkling pipe 32 with water sprinkling holes formed on its outer circumferential surface, a cylindrical wire mesh 33 concentrically provided below this, and It consists of a saucer 34, an upper tank 35, a water pipe 36 extending from the water tray 34 to the upper tank 35, and a pump 37 installed between the water pipes 36. A cylindrical water filter is created by sprinkling water on a wire mesh 33, and the used water collected in a water tray 34 is pumped up to an upper tank 35 by a pump 37 for circulation.

This air intake machine is equipped with a water filter in the air passage, so it can send cooled and dust-free air into the room. In FIG. 6, 38 is a water inlet for filling water into the upper tank 35, 39 is an operation switch plate, and 40 is a water filter device fixing frame. In particular, the above water filter is
As in the conventional system (FIG. 8), one end of the long reticulated endless belt 42 is positioned on the water tray 41, water is supplied from the water tank 42a to the water tray 41, and the long reticulated endless belt 42 is rotated in this state. Unlike band-shaped water filters that are created by driving (through which air can only pass from one direction as shown by the arrow), the filter is cylindrical and can draw in air from all around it, which increases the cooling effect.

Note that when a stationary cooling fan as shown in FIG. 9 is constructed using the water filter device 31 that creates the cylindrical water filter and the motor 1 with the fan 2, hot air flows through the louvers as shown by arrow A. 43, is efficiently cooled by a cylindrical water filter, and is blown out as cool air from the louver 44' by the fans 2 and 44 as shown by arrow B, unlike the conventional type shown in FIG. In comparison, cooling efficiency can be significantly increased. In Fig. 10, arrow A indicates the flow of hot air, 45 indicates a suction louver, 42 indicates a long mesh endless belt (Fig. 8), 42a
is a water tank, 41 is a water tray, 45 is water, 46 is a fan, 47 is a ventilation louver, and arrow B is a flow of cooled air.

As described above, the air intake device of this invention has a passage through which air passes from under the floor to above the floor, and is equipped with a fan facing above the floor. This is an air intake machine that is equipped with a patch plate that the sent air hits and diffuses.The patch plate can move up and down and when it descends, it becomes a lid that blocks the passageway opening on the floor, so it is not necessary. The patch plate does not get in the way during use. Therefore, the room can be used more widely.
