Description

  The present invention relates to a ventilator, and more particularly to a ventilator attached to a window or the like of a building.

  Shojis, sliding doors, sashes, etc. (hereinafter referred to as “window members, etc.”) attached to openings such as windows of buildings are provided with ventilators that are openings for indoor ventilation. There is a case. There are also cases where ventilation is attempted by providing an opening in the wall.

  In recent years, instead of natural ventilation due to the presence of an opening, there is a case in which a device that actively ventilates the inside and outside by turning a blower is attached.

  For example, Patent Literature 1 describes a ventilator that is arranged in a wall of a building. Patent Document 2 describes a ventilation device that is mounted in a frame such as a window member. Patent Document 3 describes a ventilator that is integrated with a ventilator.

  When it is going to install the ventilation apparatus described in patent document 1 with respect to the existing building, construction to the wall for attaching a ventilation apparatus is required. In addition, even when installing a ventilator when building a new building, it must be constructed in a housing structure that allows the ventilator to be installed.

  The ventilation device described in Patent Document 2 uses a dedicated window member or the like. For this reason, a special sash may be installed at the time of new construction, or a set or replacement of a window member of an existing building may be required.

  The ventilator described in Patent Document 3 is difficult to supply power because the ventilator and the shoji are integrated with each other, and moves with the opening and closing of the shoji. In addition, when a screen door is arranged on the indoor side of a shoji with a ventilation rod such as a decorative window, the ventilation device interferes with the screen door.

  The present invention has been made in view of the above circumstances, and it is a problem to be solved to provide a ventilator that can be attached regardless of whether a building is newly constructed or existing, and even without the presence or absence of screen doors. To do.

The structural feature of the invention according to claim 1 for solving the above-mentioned problems is that the frame body provided along the opening of the building, the frame body is openable and closable, and can be ventilated indoors and outdoors. A ventilator used for a window member comprising an opening / closing body having a ventilator communicating with
A main body disposed in the frame or the building having a first opening that opens into the building and a second opening that faces and is close to at least a portion of the ventilator;
A blower disposed within the main body and capable of moving air between the first opening and the second opening;
A duct provided in the main body and interposed between the second opening and the blower;
I have a,
A screen door is located between the ventilation tub and the second opening of the main body,
Between the screen door and the ventilation rail, it is to have a supplementary duct which communicates the flow of air between the ventilation rail and said second opening.

  In addition to the opening / closing of the window member, the ventilation rod itself may be either a ventilation rod itself that can be opened / closed so that air can be circulated / blocked or not.

  In addition, the structural feature of the invention according to claim 2 is that, in claim 1, the duct is extended in a horizontal direction from the second opening side toward the blower side, and is located above the blower. Be inclined to.

  The structural feature of the invention according to claim 3 is that, in claim 1 or 2, the on / off of the blower is interlocked with opening / closing of the opening / closing body and / or opening / closing of the ventilation box.

  In the invention according to claim 1, the first opening of the main body portion opens toward the inside of the building, and the second opening portion of the main body portion is close to and opposed to the ventilation rack. A blower is disposed in the main body, and the duct is interposed between the second opening and the blower. When the blower is driven, air moves between the first opening and the second opening. That is, air in the building (indoor) or air outside the building (outdoor) moves in the main body and the duct, and the indoor air is ventilated. In the invention according to claim 1, the second opening portion faces the ventilating bowl, and any one including the second opening section does not need to be coupled, connected or engaged with the ventilating bowl. Moreover, the ventilator of this invention is not couple | bonded, connected or engaged with the opening / closing body. Therefore, in order to attach the invention according to claim 1 to a frame body or a building, it is not necessary to use a dedicated ventilation box or an opening / closing body, and it is not necessary to change to a dedicated window member. If the window member or the like does not have a ventilation rod, the invention according to claim 1 can be installed by replacing it with a window member or the like having a ventilation rod, and it is not necessary to construct the wall of the building. In addition, when a screen door is arranged between the opening / closing body having the ventilator and the invention according to claim 1, ventilation of indoor air can be achieved by making the second opening face the ventilator over the screen door. It can be carried out. Therefore, the invention which concerns on Claim 1 can be attached to a building, without being restrained whether it is a new construction or an existing building, or the presence or absence of a screen door.

  According to the invention which concerns on Claim 2, since the shape of the duct is horizontal from the 2nd opening part side toward the air blower side and has the structure inclined upwards in front of the air blower, it is from the 2nd opening part. Even if rainwater or the like enters with the outside air, it can be blocked at the inclined part.

  In the invention which concerns on Claim 3, ON and OFF of an air blower are interlocked with opening and closing of an opening-and-closing body and / or opening and closing of a ventilation bowl. For example, when the open / close body is closed, the blower is turned on and off in conjunction with opening and closing of the ventilation tub. When the opening / closing body is opened, the blower is turned off. At this time, even if the ventilator is opened / closed, the blower is not turned on / off. This is because when the opening / closing body is opened, the indoor air is ventilated through the opening of the opening / closing body even if the blower is turned off.

Moreover, in the invention which concerns on Claim 1 , when a screen door is located between the ventilation bowl and the 2nd opening part of a main-body part, an auxiliary | assistant duct is arrange | positioned between a ventilation bowl and a screen door. Therefore, according to the fourth aspect of the present invention, a passage capable of moving air communicating with the second opening of the main body is also formed between the ventilation bowl and the screen door. There is no decline. Further, the person who wants to attach the invention according to claim 4 does not need to eliminate the screen door or replace the screen door with a dedicated product.

Representative embodiments and reference embodiments of the present invention will be described with reference to FIGS.

( Reference form 1)
Ventilator of the present reference embodiment 1, as shown in FIG. 1 includes a main body portion 2, a blower 3, a duct (4, 5).

As shown in FIG. 2, the main body 2 is a member that divides a space in which a later-described blower 3 can be installed inside by combining a lid portion 21 and a fixing portion 22. The lid portion 21 has a front surface 211 facing the room and a lower surface 212 that is substantially perpendicular to the front surface 211, and the cross section of the surface orthogonal to the longitudinal direction is an inverted L shape in FIG. 2. . A part of the lower surface 212 is formed with an indoor opening 23 (first opening) that opens in the longitudinal direction. The fixing portion 22 has an upper surface 221 fixed (in FIG. 1) inside a frame 92 on the indoor side of the opening / closing body 91 (see FIG. 1), and an opening 220 that is closed by the lid portion 21 is formed on the indoor side. . The fixing portion 22 has a lower surface 222 that comes into contact with other than the indoor opening 23 of the lower surface 212 of the lid portion 21. The main body 2 in which the lid portion 21 is set so as to close the opening 220 of the fixing portion 22 is installed so that the front surface 211 of the lid portion 21 is flush with the wall surface of the room and fits neatly inside the frame body 92. . Body 2, when ventilation apparatus of the present reference embodiment 1 is shorter than the width direction of the frame body 92 to be attached, apart from the above the fixed portion 22, the side of the fixed portion 22 that faces the frame 92, in FIG. 2 As shown in the figure, a bracket 93 attached so as to protrude downward from above the frame body 92 is fixed by screws or the like.

  Returning to FIG. 1, the main body 2 is further provided with a duct defined therein. The duct has an internal path 5 and an extension 4. The internal path 5 is provided with a blower inside thereof.

  First, the extension 4 is extended from an internal opening 41 that opens to the inside of the main body 2 toward an external opening (second opening) 42 that opens to face the ventilation rod 94 of the opening / closing body 91. ing. The extension portion 4 is extended in a substantially horizontal direction from the outer opening portion 42 toward the fixing portion 22, and the inner opening portion 41 is directed upward toward the center portion of the main body portion 2 before reaching the inner opening portion 41. Since it is located, the middle is inclined. The external opening 42 of the extension portion 4 is opened to face the ventilation rod 94 located above the opening / closing body 91. The external opening 42 is close to the ventilation pole 94. The degree of proximity is such that the necessary amount of air sent out by the blower 3 can enter and exit through the ventilator 94. That is, the greater the degree of proximity (the shorter the distance between the ventilation rod 94 and the external opening 42), the more the air can be ventilated without leaking from the facing portion. And it is the extension part side opening part 51 of the internal path 5 which covers the air blower 3 (for example, which has a crossflow fan) that the internal opening part 41 of the extension part 4 communicates.

  The blower 3 is installed in the fixed portion 22 in a state covered with the installed path 5. As shown in FIG. 2, the blower 3 is long in the width direction of the opening / closing body 91 similarly to the main body 2, and a motor 6 for driving is attached to one end. As shown in FIG. 1, the internal path 5 includes an extension side opening 51 that communicates with the internal opening 41 of the extension 4 and a lid side opening 52 that communicates with the indoor opening 23 of the lid 21. The blower 3 is located between the two. The internal path 5 has a first partition 53 and a second partition 54 so that the air moves between the extension part side opening 51 and the cover part side opening 52 by the rotation of the blower 3. The blower 3 is covered. The first partition 53 covers the upper side of the blower 3 from the extension portion side opening 51. The second partition 54 is located below the blower 3 from the extension part side opening 51 and closer to the extension part side opening 51.

The motor 6 can switch the rotation direction of the blower 3. For example, the blower 3 can be switched by a motor 6 between forward rotation for exhausting indoor air and reverse rotation for intake of outside air into the room. Further, the rotation (on) and the rotation stop (off) of the blower 3 are linked to the opening / closing of the opening / closing body 91 and / or the opening / closing of the ventilation rod 94. For example, the blower 3 is rotated with the ventilator 94 open, and the blower 3 stops rotating when the ventilator 94 is closed. Further, the blower 3 stops rotating when the opening / closing body 91 is in an open state. As the opening / closing body 91, there are a sliding window, an outer opening window, an inward window, a raising / lowering window, a louver window or a non-opening and closing window that can be switched between opening and closing states. Te, it can be installed ventilator of the present reference embodiment 1. Here, the on / off interlock of the blower 3 by opening / closing the opening / closing body 91 is based on the open state when the opening / closing body 91 is a sliding window. This is to avoid being done. However, if the opening / closing body 91 is in the open state, ventilation can be performed without ventilating with the ventilator, so that the specification can be made to stop rotating regardless of whether or not the ventilation pole 94 portion is blocked.

Ventilator of the present reference embodiment 1, for example, the case of exhausting the room air, the blower 3 motor 6 is driven is normally rotated, the indoor air of the inner設路5 from the indoor opening 23 of the main body portion 2 The lid side opening 52 is moved and led to the internal path 5. Then, the air moves from the extension portion side opening portion 51 of the internal path 5 to the internal opening portion 41 of the extension portion 4 and is discharged from the external opening portion 42 of the extension portion 4 to the ventilation rod 94. In addition, when the outside air is sucked into the room, the motor 6 is driven to reversely rotate the blower 3 in the reverse manner of the exhaust. The outside air moves from the external opening 42 of the extension part 4 to the internal opening 41 and the extension side opening 51 of the internal path 5 via the ventilation rod 94, and the lid side opening 52 of the internal path 5. Through the indoor opening 23 of the main body 2.

  In addition, at the opening of the building, it rotates in conjunction with the opening and closing of the ventilation rod 94 on the outdoor side of the ventilation rod 94 (on the opposite side to the surface where the internal opening 41 of the extension 4 is located). A valve member 95 is attached. The valve member 95 is plate-shaped, and the upper part is pivotally supported so that the lower part rotates. The valve member 95 has a shaft-supported position close to the ventilation rod 94, a state substantially parallel to the ventilation rod 94 is a closed state, and a state where the lower part is separated from the ventilation rod 94 is an open state. is there. The valve member 95 is opened in conjunction with the ventilation rod 94 being opened, and the valve member 95 is closed in conjunction with the ventilation rod 94 being closed. The open state of the valve member 95 is regulated to an acute angle. By prescribing the turning angle to some extent, it is possible to prevent rainwater or dust in the air from entering the extension portion 4.

Ventilator of the present reference embodiment 1, the external opening 42 of the extension portion 4 in the ventilation rail 94 above the closing member 91 is to be located, it is placed above the opening and closing member 91. Since the closing member 91 and the ventilator of the present reference embodiment 1 is not integral, the case of the opening and closing member 91 there is no ventilation rail 94 may be changed to the closing body 91 with ventilating rail 94, is a dedicated opening 91 There is no need. Moreover, in order to attach the ventilation apparatus of this reference form 1, the wall of a building is not constructed. Therefore, it is possible to attach the ventilator of this reference form 1 without depending on being a new construction or an existing building. In FIG. 1, a screen door 96 is located under the extension 4. Since the external opening 42 of the extension part 4 is installed so as to be close to the ventilation rod 94, the upper position of the screen door 96 is lower than the ventilation rod 94 of the opening / closing body 91. Here, when the screen door 96 has a height located between the ventilation rod 94 and the external opening 42 of the extension portion 4, the screen door 96 is not changed to the height screen shown in FIG. The external opening 42 of the extension 4 is brought close to the screen door 96 as it is. Outside air is sucked from the external opening 42 of the extension portion 4 through the ventilation rod 94 and the screen door 96, and indoor air is exhausted from the external opening portion 42 of the extension portion 4 to the screen door 96 and the ventilation rod 94. Therefore, even if the screen door 96 is arranged between the closing body 91 and ventilation device of this preferred embodiment 1, the ventilator of the present reference embodiment 1 can be ventilated to 96 over screens.

  Furthermore, since the duct has a shape in which the internal opening 41 of the extension 4 is located above the external opening 42 and is inclined upward in front of the blower 3, the duct has entered from the external opening 42 together with the outside air. Rainwater and garbage can be stopped at the slope, and further entry into the ventilator can be suppressed.

(Embodiment 1 )
Ventilation device of the first embodiment, ventilator and the basic structure and effects of the reference embodiment 1 is the same. Hereinafter, mainly different parts will be described.

As shown in FIG. 4, when the screen door 96 is located between the ventilation rod 94 and the external opening 42 of the extension portion 4, the ventilation device according to the first embodiment is interposed between the ventilation rod 94 and the screen door 96. An auxiliary duct 43 that can be arranged is provided. The auxiliary duct 43 is a member opened in the vicinity of the ventilation pole 94 and the screen door 96. The duct side opening 431 that opens to the screen door 96 is arranged so as to coincide with the external opening 42 of the extension 4 in the vertical and horizontal directions, and communicates with the external opening 42 of the extension 4. The auxiliary duct 43 is fixed to a bracket 921 attached above the frame body 92. Further, the auxiliary duct 43 may be made of, for example, a rubber sponge.

  By arranging the auxiliary duct 43 between the ventilation rod 94 and the screen door 96, the ventilation efficiency is improved as compared with the case where the auxiliary duct 43 is not provided. In addition, a ventilator with better ventilation efficiency than the case of FIG. 3 is installed without removing the screen door 96 located between the ventilation rod 94 and the external opening 42 or changing the shape of the screen door 96. it can. However, the extension 4 and the auxiliary duct 43 are preferably provided with a member (for example, a rubber member) for reducing air leakage and friction at a portion in contact with the screen door 96.

(Other embodiments)
The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, the position of the indoor opening 23 is not necessarily downward due to the positional relationship of the lid-side opening 52 of the internal path 5. Further, the indoor opening 23 may be in a state where a net-like member is attached or nothing is attached.

  In addition, the size of the opening of the external opening 42 may be a size that opens to the whole ventilating rod 94 or a size that opens to a part thereof. In consideration of design, the size of the opening is preferably equal to or less than the size of the ventilation device.

  In addition, the opening and closing of the valve member 95 can be interlocked with the on / off of the blower 3 instead of interlocking with the opening and closing of the ventilation rod 94. This is because the on / off state of the blower 3 itself is linked to the opening / closing of the opening / closing body 91 and the opening / closing of the ventilation bowl 94. Or the structure which does not interlock | cooperate with said opening / closing may be sufficient. When the ventilator performs only exhaust, the valve member 95 is opened by the flow of exhaust, and the valve member 95 is naturally closed when there is no flow of exhaust. Since the valve member 95 opens and closes at an acute angle with the upper side as a rotation axis, the valve member 95 closes if there is no flow from the indoor side to the outdoor side, and is pressed against the ventilation rod 94 side when outside air flows to the valve member 95. . Therefore, the outside air is blocked by the valve member 95 and is unlikely to enter the extension portion 4 from the ventilation rod 94, and rainwater together with the outside air can prevent entry of dust.

Further, the valve member 95 is not necessarily an essential member. In particular, in the modified example of the ventilation device of Reference Embodiment 1 shown in FIG. 3, there is a distance between the valve member 95 and the external opening 42 of the extension 4. There is a high possibility of falling before reaching the external opening 42 of the extension 4 due to its own weight.
