Description

The present invention relates to an apparatus for ventilating indoor air by exhausting or sucking outdoor air, and particularly relates to an apparatus for easily ventilating and cooling indoor hot air that has become hot in summer or the like at low cost.

The conventional technology is as follows. For example, Patent Document 1 proposes an outside air introduction blower in which a blower having a blower support means attached to a window is formed integrally with a screen door. Patent Document 2 proposes a screen door with a ventilation fan in which an electric ventilation fan is provided on a reinforcing bar of the screen door. Further, Patent Document 3 and Patent Document 4 propose a planar fastener as a method of attaching an article to a net.

Registered Utility Model No. 3014306 Japanese Unexamined Patent Publication No. 55-122987 Japanese Utility Model Publication No.57-106994 microfilm Japanese Utility Model No. 63-54799 microfilm

As described above, problems still remain in each technology. For example, in Patent Documents 1 and 2, since the blower support means is attached to the window or window frame in advance, even if you want to attach it immediately after the installation position is fixed, you must have appropriate tools and skills. . And if you attach it to a window, you can't do it right away if you want to remove it. Of course, the work for restoring the original state after removal is also required. In addition, since the blower support means is directly attached to the window or the window frame, there is a problem that secondary pollution such as noise due to vibration may occur.

Next, the difference between the attachment of articles to the net and the technique of the adhering material to the net using a woven fabric having a large number of ridges and loops such as planar fasteners as in Patent Documents 3 and 4 is also examined. saw. In conclusion, these planar fasteners can be used for thin, light-weight ones such as emblems, but they are somewhat unhealthy for ventilating devices that are somewhat heavy and vibrate. It was found that this problem remains unsuitable for practical use. In other words, when a large number of scissors and loops are in contact with each other through a mesh, a large number of scissors are pressed from both sides of the hook-and-loop fastener by a human hand, and what percentage of the scissors actually pass through the mesh. , And what percentage of the loop reaches the opponent's eyes at the passing position, and the loop direction and angle are appropriate, and what percentage entangles with the heel, and finally effectively demonstrates the supporting force It must be said that it is very uncertain what percentage of that will be done.

Although it was a simple in-house test, it was less than 25% that the test surface fastener with 100 heels was 10 times, and the heel and loop were surely able to exert the entanglement force. Moreover, there remains a problem that it is not known whether the holding power can be exhibited without any problem after all the hooks and loops are entangled. Furthermore, the diameter of the wrinkles that pass through the mesh is naturally much smaller than that of the mesh, and there remains anxiety in terms of strength. Also, if you carefully observe the situation of falling off, the heels entangled in the loop stretches out and stretches, and the heels finally come off and drop out. This means that all the heels will fall out as they grow without permission when the entire heel and loop are supported to support the entire weight. And it repeats sequentially to the next entangled bag and loop. Although it depends on the design method, this planar fastener is considered to be suitable for the purpose of sticking a lighter one than the purpose of supporting the load, and is considered to be less practical as a fixture used in this case.
Accordingly, an object of the present invention is to provide a screen door ventilator for suctioning outside air or for indoor air exhaust that can be easily removed at a low cost without remodeling the screen door and is not used.

In order to solve the above-described problems, the present invention provides a screen door ventilator to be attached to an arbitrary mesh in a screen door, the housing having planar openings for intake and exhaust, and the housing.

Further, the contact means has a fixture that faces the opening of the housing across the screen door, and the opening and fixture of the opposing housing are made of a magnetic material. by the action of attractive force of the magnet during, opening is configured to secure the housing so as to be in close contact along the network. (Claims Claim 3)
In addition, the contact means has a fixing member that opposes the opening of the casing across the screen door, and the fixing member locks the projecting member inserted through the reduced diameter portion. comprises a hole, so that the reduced diameter portion of the protruding member extending through the meshes, by being locked by the locking hole of the fastener, the opening to secure the housing so as to be in close contact along the network It is configured. (Claims 4)
Further, at least one of the porous material and the heat absorbing member is attached to the casing so that the porous material having the plurality of ventilation holes or the heat absorbing member having the plurality of ventilation holes is positioned on the flow path of the ventilation. It has a configuration. (Claim 5)

Moreover, it is a ventilator attached to an arbitrary position in a screen door, and has a bowl-shaped lid (housing) having a flat opening surface, and a part of the lid (housing) is opened to open the lid (housing). The fan includes a fan fitted so as to penetrate the inside and the outside, and a fixture that closes the screen (opening) of the lid (housing) to the screen door.
Moreover, it is a ventilator attached to an arbitrary position in the screen door, and has a bowl-shaped lid (housing) having a flat opening surface, and a part of the lid (housing) is opened to open the lid (housing). A fan fitted so as to penetrate the inside and outside, a fixing tool that closes the screen (case) close to the screen door, and a part of the lid (case) that is open. A structure having a plurality of projecting members arranged in the vicinity and passing through the mesh of the screen door, and a plurality of receiving terminals which are part of the fixture and are electrically connected to the projecting member from the opposite side of the screen door It is said.

Moreover, it is a ventilator attached to an arbitrary position in the screen door, and has a bowl-shaped lid (housing) having a flat opening surface, and a part of the lid (housing) is opened to open the lid (housing). A fan fitted so as to penetrate the inside and outside, a fixture that closes the screen (opening) of the lid (casing) close to the screen door, and the lid (housing) and the fixture for preventing the fall. A connecting band having a flat shape that crosses over one edge of the screen door and minimizes a gap generated when the screen door is opened and closed so as not to interfere with the power cord or to pass the power cord.

The screen doors in this screen door ventilator include those with various nets, including those for insect protection installed so as to cover openings such as windows and doorways. In general, screen doors, screen doors and screens in homes are the main targets. In other words, the ventilator in this screen door ventilator does not replace this screen door with a new ventilator, but tries to obtain a new ventilation function by adding new technology while using the conventional screen door. In addition to air blowing and air cooling, adding a filter or the like to expand application examples such as deodorization, sterilization or aromatherapy is also included.

The lid (housing) in the screen door ventilator can cover the net surface with a flat opening in a certain range, and includes a plate-like member in addition to a container. Furthermore, the shape of the cross section is not limited to a circle or a rectangle. Also, various sizes of the opening surface can be applied, and the opening surface of the fan is in the middle of the depth of the lid (housing), that is, arranged so as to float between the opening surface of the fan and the screen door screen. Accordingly, the air passing through the screen door can be decelerated to reduce the resistance. The lid (housing) of the screen door ventilator can be combined with the opening of the fan with a design on the surface. For example, it can be configured such that a breeze comes out of the forest with a forehead motif depicting the forest. Furthermore, in order to reduce the weight of the lid (housing), it is possible to include foaming materials such as foamed resin as well as resin. Moreover, the cover part (housing) and the cover cover on the surface can be separated, and a cover cover suitable for various applications can be attached to the cover part (housing) made into a common part.

The fan in the screen door ventilator is installed in a narrow space close to the screen door, imparts kinetic energy to the air, and transfers air from one side of the screen door to the other. Various fans including axial fans can be applied. For example, general DC fans, AC fans, fan motors and the like are also included. Of course, it is important that it is lightweight, thin, and quiet. In addition to the household power supply, the fan power supply includes a battery, a transformer, solar power generation, etc., and can be integrated with the timer device for automatic operation. Further, regarding the arrangement of the fans, not only the position but also a combination of a plurality of units, large and small sizes, or an integrated combination type of discharge and suction can be freely used, which helps to widen the range of applications. In addition, the sensor unit is placed on the ventilation flow path together with a temperature / humidity meter, etc. to automatically operate when the temperature difference between the inside and outside exceeds a certain level, or to automatically start and stop when the specified temperature or humidity is reached. Etc. are also possible. Although partly described, the route from the power source to the fan should be appropriately selected for each device. In addition to connecting directly from the main unit to a household outlet with a cable, it is also possible to connect from the middle of the connecting band or from the opposite side with a screen door in between. Also, a control box including a switch may be installed in the vicinity of the window frame to make a thin cable that does not stand out from the main body. Control includes temperature control and time control as well as environmental control.

The projecting member in the screen door ventilator has a function of handing over the load to the screen door screen in response to vibrations caused by rotation of the fan as well as the total weight of the device. Therefore, the protruding member has a protruding portion that penetrates the mesh of the mesh or blocks the mesh wire even in a direction parallel to the mesh surface. For example, FIG. 6 schematically shows a cross section of a net, but as long as the net and the projecting member are in close contact, both the projecting members 25a and 25b are resistant to displacement parallel to the net surface. It shows that it has.
Further, by utilizing the fact that the screen door mesh is usually tensioned, the protruding member is positioned on the distal end portion having an outer diameter larger than the opening width of the mesh and on the proximal end portion side relative to the distal end portion. By using a plurality of these in the shape of having a reduced diameter portion having a diameter smaller than that of the tip portion, these are adjacent to each other or removed from one mesh, and the meshes in the vertical and horizontal directions are more strained. It also includes making it difficult to come off. On the other hand, if the outer diameter of the tip portion is too large, it may be difficult to remove depending on the diameter and shape of the reduced diameter portion, and the net may be damaged. Further, since the protruding member acts integrally with the contact means described later, depending on the contact means, it may be a simple pin or a protrusion. Further, there are included means for preventing the tip of the pin from being divided and opening the mesh after it is inserted, or preventing the needle from extending from the tip of the pin and separating the opening from the mesh.

The close contact means in this screen door ventilator is a mechanism for the opening surface of the lid (casing) to be in close contact with the screen door screen. It is easy to attach and detach, is lightweight and inexpensive, and does not fall off easily. It is an important factor not to hurt. The contact means can be broadly classified into two types: one integrated with the above-described protruding member (referred to as an integral type) and one requiring a fixing tool separated from the protruding member (referred to as a separate type). . The diameter-reduced portion of the projecting member according to claim 2, that is, the contact means by the constriction or the step is an integral type. As an example of a close contact means that sandwiches a screen door with a fixing tool from the opposite side of the mesh surface, a flexible fixing tool that uses a magnetic force of a magnet or a locking hole that locks with a reduced diameter portion of a protruding member Etc. are separate types. In the case of a magnet, the case where the magnet is a magnet and a magnet is also included. Furthermore, it includes having an iron magnet holder that wraps the magnet in order to increase the attractive force of the magnet. In addition, in the case of a flexible fixture, in addition to a locking hole adapted to be held by a protruding member, it is possible to have a deformed hole, a hole with a slit, or a number of pin holes, such as a rain cover or a blindfold. Can also be used. Further, a close contact means for fixing by inserting a pin with a head passing through the mesh of the screen door like a pin type of a tie pin and fixing it is also included.

In addition, a plurality of conductive projecting members as described above (this item has elements different from the projecting member described above in addition to the item (0009), so that this item and (0009) A plurality of receiving terminals with respect to the projecting member only) are included in the so-called separation type in this contact means in a broad sense. In this case, non-conduction is applied as the material of the mesh. Further, these close contact means have no problem as to which side of the screen door the lid (housing) is attached. Furthermore, even if it is a one-way fan, it is also included that it is a double-sided netting type in which both sides of the fan can be fixed to the screen door when used. Further, it includes the formation of a slight step on the net surface as a whole or part of the lid portion (housing) and the net surface being brought into close contact with each other by a fixture, thereby increasing the resistance to slippage.

The porous material in the screen door ventilator mainly cools the air to be ventilated by absorbing and holding water and the heat of vaporization caused by evaporation. Accordingly, it is desired that this porous material has excellent hydrophilicity and high water retention capacity. It is also effective to use a water supply type that is frozen in advance or replenished as needed. The heat absorbing member in the screen door ventilator is similar to the one described above, which cools the air to be ventilated or assists the cooling, and has a heat insulating material sealed in a package or heat for facilitating heat exchange. It includes a conductive plate. For example, it is also effective to facilitate heat transfer with fins of an aluminum plate.

The connecting band in the screen ventilator is effective in a so-called separation-type fixture, in addition to the purpose of preventing the fall when the main body and the fixture are separated from each other, as well as passing the cable wiring to the opposite side of the screen door. Specifically, thin fiber cloths, strings, tapes, flat cables, film cables, and the like are possible. Furthermore, the use of this connection band is also included. In addition, these connecting bands include making them transparent so as not to stand out.

Since the present invention has a configuration as described above, the present invention is a simple ventilation device that can be used after being attached to an existing screen door, and exhausts indoor air or sucks outside air without requiring a new place. Or even cooler the outside air to supply and make the room more comfortable. In Japan, which is hot and humid in summer, for example, ventilation and ventilation are possible from the north side to the south side in the summer and from the south side to the north side in the winter, which can easily improve the housing environment. In addition, it can contribute to power saving by sucking inexhaustible outdoor cold air in the summer night and living without an air conditioner. Furthermore, the effect can be very great, such as the introduction of aesthetic and artistic sensations into a screened screen.
