Abstract

In both horizontal posture and vertical posture of an on/off valve body, the centroidal position of the on/off valve is set to be located on one side of a vertical line passing a supporting axis at all times. Consequently, in both horizontal posture and vertical posture, torque acts constantly in the valve closing direction, thus closing the on/off valve by its own weight. Since the fixing direction of the on/off valve can be set not only in the horizontal direction but also in the vertical direction, workability of piping work is improved. As another embodiment, a lattice inside an exhaust pipe including outlet cover, for protecting against insects, is removed, an on/off valve capable of being switched between horizontal posture and vertical posture is fixed in the opening left by the removal, and the rear end of the exhaust pipe is brought into tight contact therewith. Since the on/off valve is installed in a relatively large space section within an outlet cover, workability of fixing work is improved.

Disclosure of the invention

Problems to be solved by the invention

[0003] By the way, the ventilation hose as described above is drawn out together with the refrigerant pipe connecting the heat exchange between the indoor unit and the outdoor unit to the outside, so that it is led out to the outside depending on the position of the outdoor unit. Pipes and ventilation hoses that have been removed may be pulled out horizontally as well as vertically.

[0004] In such a case, the on-off valve device connected to the rear end of the ventilation hose is closed by its own weight when the operation is stopped, and the on-off valve corresponds to either a vertical posture or a horizontal posture. It is necessary to make the valve open by air pressure during operation.

[0005] However, the on-off valve device described in Patent Document 1 is disclosed only when the device main body is used in a horizontal posture, and is considered when used in a vertical posture. Therefore, when using the device body in a vertical position, the on-off valve is always open, It may not function as an on-off valve device for insect repellent.

[0006] In view of the above, an object of the present invention is to provide an on-off valve device having an on-off valve that can be opened and closed in accordance with whether the device main body is used in either a horizontal posture or a vertical posture. Another object of the present invention is to provide an air conditioning apparatus and an exhaust pipe on / off valve mounting method that can improve the on / off valve mounting workability.

Means for solving the problem

[0007] In order to achieve the above object, the present invention provides an on-off valve device in which an on-off valve is supported by an apparatus body having a valve hole so as to be capable of opening and closing about a support shaft. While maintaining the horizontal direction, the device body can be switched between a horizontal posture in which the valve hole is opened in the horizontal direction around the support shaft and a vertical posture in which the valve hole is opened in the vertical direction. The valve is closed by its own weight when the operation is stopped, and is opened by the pressure of the fluid passing through the valve hole in the operation state.

[0008] According to the above configuration, the on-off valve can cope with both the horizontal posture and the vertical posture. At that time, the on-off valve is closed by its own weight when the operation is stopped, and is opened by the pressure of the fluid passing through the valve hole in the operation state, which is useful as an on-off valve device.

[0009] Further, the on-off valve includes a valve body arranged to open and close the valve hole on one side around the support shaft, and a balance weight arranged on the other side, and the horizontal posture of the apparatus main body In both the vertical posture and the vertical posture, the center of gravity position of the on-off valve is set so as to be always on one side with respect to the vertical line passing through the support shaft.

[0010] According to the above configuration, the on-off valve is set so that the center of gravity is always located on one side with respect to the vertical line passing through the support shaft in both the horizontal posture and the vertical posture of the apparatus main body. Therefore, in both the horizontal posture and the vertical posture of the device main body, the rotation moment in the valve closing direction always acts, and the on-off valve is closed by its own weight. Therefore, when the operation is stopped, the on-off valve switches to the valve opening posture force closed state, and the mounting direction of the on-off valve device can be set not only in the horizontal but also in the vertical direction. It becomes.

At this time, the support shaft maintains the horizontal direction in both the horizontal posture and the vertical posture of the apparatus main body. Therefore, in the region where the device body is rotated 90 degrees between the horizontal posture and the vertical posture around the support shaft, the center of gravity position of the on-off valve is relative to the vertical line passing through the support shaft. It will always be located on one side and the piping workability will be good.

[0012] The on-off valve can also be used for a variety of applications such as insect repellent installed at the end of a pipe led out of the room to the outside. Furthermore, an on-off valve device may be connected to the exhaust pipe of the filter cleaning device that sucks and exhausts dust adhering to the filter of the air conditioner with a suction fan.

[0013] Furthermore, the filter cleaning device includes a suction fan for removing dust attached to the air purification filter by using air suction force, and an exhaust pipe for exhausting air containing the sucked dust. In the air conditioner equipped with a device, since the air exhausted from the exhaust pipe contains dust, there is a lattice part formed with many insect repellent slits formed in the outlet cover. There is a risk that dust in the exhaust will adhere to the grid and block the grid. Therefore, an opening / closing valve device for repelling insects is required instead of the lattice portion or on the upstream side of the lattice portion.

[0014] In order to dispose this on-off valve device in the lattice portion that is no longer necessary as a part of the outlet cover, it is necessary to insert a cutter around the lattice portion to cut the lattice portion, or to strike the lattice portion with a screwdriver or the like. And an on-off valve device is attached to the removed opening.

[0015] Then, there is no need to newly provide a branch box as in the prior art, and the on-off valve device is also installed in a relatively large space in the outlet cover, so that the mounting workability is good. Become.

[0016] In this case, an opening is formed in the cover body of the outlet cover, and the exhaust force bar is detachably attached so as to cover the opening. As a result, the grid portion can be removed with the exhaust cover removed, and then the on-off valve device can also be attached with an external force, so that the mounting workability can be improved.

[0017] Further, the present invention is provided with an outlet cover that includes a refrigerant pipe and an exhaust pipe that connect the indoor unit and the outdoor unit by pipes and is attached to the outdoor wall, and exhausts exhaust from the exhaust pipe to the outside. For this purpose, an on-off valve device for opening and closing an opening formed in the outlet cover is provided. The on-off valve device is closed by its own weight when the operation is stopped, and is opened by the exhaust pressure generated in the exhaust pipe during operation. In close contact with the rear end of the exhaust pipe.

[0018] According to the above configuration, the on-off valve device is directly attached to the outlet cover. Such a branch box becomes unnecessary, and the on-off valve device is installed in a relatively large space in the outlet cover, so that the installation workability is improved.

[0019] Here, the outlet cover includes a cover main body including the refrigerant pipe and the exhaust pipe, and an exhaust cover that covers an opening formed in the cover body and forms an exhaust passage therein, and the exhaust force The bar is detachably attached to the cover body.

[0020] According to this configuration, the exhaust cover is detachably attached to the cover body, so that the opening / closing device can be easily attached.

[0021] Further, the outlet cover is set so that it can be attached in either a vertical posture in which the cover body is attached to the outdoor wall in a vertical state or a horizontal posture in which the cover body is attached in a horizontal state. However, it can be mounted by rotating 90 degrees around the center of the exhaust pipe so that its support shaft is always horizontal.

[0022] According to the above configuration, the outlet cover can be set to be either vertically or horizontally depending on the installation status of the outdoor unit of the air conditioner. At this time, in order to close the on-off valve device by its own weight, the on-off valve device must always keep its support shaft in a horizontal position. In order to satisfy this, it is set so that the on-off valve device can be attached to the opening even if it rotates 90 degrees. If it does so, the on-off valve apparatus can respond to both vertical installation and horizontal installation of an outlet cover.

[0023] The exhaust pipe may be connected to a ventilation device as shown in Patent Document 1, but is preferably connected to a suction fan of a filter cleaning device of an indoor unit. According to this configuration, the filter force that removes dust in the air When the dust is removed using the air suction I force, even if dust is contained in the air, the opening / closing valve does not clog the dust. Can be issued.

The invention's effect

[0024] As described above, according to the present invention, the center of gravity position of the on-off valve is always set to one side with respect to the vertical line passing through the support shaft in both the horizontal posture and the vertical posture of the apparatus main body. Therefore, in both horizontal and vertical postures, the rotational moment in the valve closing direction always acts and the on-off valve closes with its own weight. For this reason, the mounting direction of the on-off valve device can be set not only in the horizontal direction but also in the vertical direction, which improves piping workability. [0025] Further, the grid portion formed in the cover body of the outlet cover is removed, and an opening / closing valve device that can be switched between the horizontal posture and the vertical posture is attached to the opening formed there, Is closed by its own weight when the operation is stopped and close to the rear end of the exhaust pipe so that the valve is opened by the exhaust pressure generated in the exhaust pipe during operation. Become.

BEST MODE FOR CARRYING OUT THE INVENTION

[0028] <First embodiment>

In the present embodiment, an example in which a filter cleaning device is mounted in an indoor unit of a separate type air conditioner having a main function of an air conditioning function as an air conditioning device, and an opening / closing valve device is provided in an exhaust passage thereof. explain.

[0029] As shown in Figs. 1 and 2, the air conditioner of the present embodiment has an interior of the indoor unit 1 between a suction port 2 formed at the upper portion and an outlet port 3 formed at the lower portion. In the ventilation path, the filter 4, the indoor heat exchanger and the blower fan (both not shown) are arranged in this order with the suction port 2 side as the upstream side, and a filter cleaning device 5 for cleaning the filter 4 is provided. .

[0030] The filter cleaning device 5 includes a dust removal box 10 and 11 on both sides sandwiching the filter 4, a suction fan 12 as a suction means, and a suction unit that sucks dust-containing air from the dust removal boxes 10 and 11 into the suction fan. A path 14 and moving means 15 for moving the filter 4 back and forth in the vertical direction perpendicular to the length direction of the dust removal box are provided. The filter cleaning device 5 removes dust adhering to the filter 4 by sucking the air in the dust removal boxes 10 and 11 across the filter with the suction fan 12 while reciprocating the filter 4 in the vertical direction. Then, the air is discharged from the suction fan 12 through the exhaust pipe 16 to the outside through the partition wall 17. An opening / closing valve device 26 shown in FIGS. 3 to 7 is provided at the outlet side end of the exhaust pipe 16.

The on-off valve device 26 includes a cylindrical device body 27, an opening / closing valve 29 that opens and closes the valve hole 28 of the device body 27, and a protective cover 30 that covers the opening / closing valve 29, as shown in FIG. Like vertical posture, figure It can be used in two postures, the horizontal posture as shown in Fig. 5.

[0032] As shown in FIGS. 6 and 7, the apparatus main body 27 includes a cylindrical portion 27a that fits an end portion of the exhaust pipe 16, and a flange 27b that is formed at the outer peripheral portion of the intermediate position. The cylindrical portion 27a is formed with a step portion 27c that restricts the entry of the end of the exhaust pipe 16 at the flange 27b portion. The rear end surface of the cylindrical portion 27a is an inclined surface cut obliquely, and this inclined portion functions as the valve hole 28.

[0033] The on-off valve 29 is supported on the outer peripheral portion of the cylindrical portion 27a by a support shaft 31 so as to be capable of opening and closing, and is arranged so as to open and close the valve hole 28 on one side of the support shaft 31. A body 29a and a balance weight 29b arranged on the other side are provided.

[0034] The on-off valve 29 is supported by the center of gravity G of the on-off valve 29 in any of the horizontal posture (see FIGS. 5 and 7) and the vertical posture (see FIGS. 4 and 6) of the device body 27. It is set so that it is always located on one side with respect to the vertical line N passing through the shaft 31. The valve is closed by its own weight when the operation is stopped, and the valve opens through the valve hole 28 in the operation state (exhaust). It is supposed to do.

Here, the “horizontal posture” of the apparatus main body 27 refers to a posture in which the tube center of the tube portion 27a is in the horizontal direction, and refers to the state shown in FIG. Further, the “vertical posture” of the apparatus main body 27 means a posture in which the cylinder center of the cylinder part 27a is in the vertical direction !, the state shown in FIG.

The center of gravity G is “always located on one side with respect to the vertical line N” means the following region. As shown in FIG. 4, two straight lines that are orthogonal to each other through the support shaft 31 are denoted as E and F, and the straight line E is aligned with the vertical line N in FIG. In FIG. 4, the four regions defined by the two straight lines E and F are referred to as A, B, C, and D in the counterclockwise direction of the upper left force.

In the present embodiment, the center of gravity G of the on-off valve 29 is located in the B region. In Fig. 4, when the center of gravity position G of the on-off valve 29 is set in the B region, a counterclockwise rotational moment is generated in the on-off valve 29 in the vertical posture of the device body 27, and the on-off valve 29 is moved in the closing direction by its own weight. Rotate

[0038] If the center of gravity position G of the on-off valve 29 is set to the C and D regions in the vertical posture of the apparatus body, a clockwise rotational moment is generated in the on-off valve 29, and the on-off valve 29 opens due to its own weight. Rotate in the direction of [0039] When the center-of-gravity position G of the on-off valve 29 is set to the A region, the on-off valve 29 generates a counterclockwise rotational moment in the vertical posture of the device body 27, and the on-off valve 29 moves in the closing direction by its own weight Although it rotates, in the horizontal posture of the device body 27 (see FIG. 5), the A region is located on the opposite side across the vertical line E. Therefore, a clockwise rotational moment is generated in the on-off valve 29, and the weight of the on-off valve acts in the valve opening direction. Accordingly, the center of gravity of the on-off valve 29 is correspondingly U, and the region is the B region.

[0040] When the center of gravity G of the on-off valve 29 is located in this B region, the filter cleaning device 5 is closed by its own weight when the operation of the filter cleaning device 5 is stopped, and opened by the pressure of the fluid (exhaust gas) passing through the valve hole 28 in the operation state. It comes to speak. Since the center of gravity G of the on-off valve 29 is set in the B region, the valve body 29a constituting the on-off valve has a relatively long and thin cross-sectional shape, and the balance weight 29b located on the opposite side across the support shaft 31 is short and It is an aspect in which the wall thickness is increased. The support shaft 31 has a horizontal direction in both the horizontal posture and the vertical posture of the apparatus main body 27.

The protective cover 30 is disposed so as to cover the entire periphery of the on-off valve 29, and its end is engaged with the flange 27b and integrated with the apparatus main body 27. The on-off valve device 26 is bundled on the outdoor wall side of the partition wall 17 together with a refrigerant pipe and a signal line wiring connecting the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit. It is wound, and the tip force of the protective cover 30 can also release the exhaust gas that has passed through the on-off valve 29.

[0042] In addition to the use example described above, the on-off valve device 26 may be configured to engage and fix the device main body 27 in a cosmetic outlet cover attached to the outdoor wall.

[0043] In the above configuration, when the on-off valve device 26 is used in a vertical posture as shown in FIGS. 4 and 6, the position of the center of gravity G is always one side of the vertical line N passing through the support shaft 31. Since it is located in the region, the rotation moment in the valve closing direction always acts in the vertical posture of the device body 27, and the valve 29 is closed by its own weight.

On the other hand, when the on-off valve device 26 is used in a horizontal posture as shown in FIGS. 3, 5, and 7, the position of the center of gravity G is always equal to the vertical line N passing through the support shaft 31. Located in side B area. Therefore, the rotation moment in the valve closing direction is always applied in the horizontal posture of the device main body 27, and acts to close the on-off valve 29 with its own weight. In this way, the on-off valve device 26 is located in the B region where the center of gravity G of the on-off valve 29 is on one side with respect to the vertical line N in both the vertical and horizontal postures. Therefore, the rotational moment around the support shaft 31 of the on-off valve 29 acts in the valve closing direction. Therefore, the on-off valve 29 is closed due to its own weight when the filter cleaning device 5 is stopped, and is opened due to the exhaust pressure S generated in the exhaust pipe 16 during operation, and insects enter the room through the exhaust pipe 16 as well. Can be prevented.

In the above-described embodiment, a grid-like filter that removes large dust may be provided on the upstream side of the suction fan 12, whereby large dust is removed and only the fine dust is opened and closed. You may make it discharge | emit to the outdoor from. In the above-described embodiment, an example in which the opening / closing valve device 26 is attached to the end of the exhaust pipe 16 of the filter cleaning device 5 is shown, but it can also be attached to the end of the ventilation pipe of the ventilation device.

As shown in FIGS. 8 to 13, the air conditioner of the present embodiment is configured to remove the dust removed by the filter cleaning device 5 from the suction fan 12 through the exhaust pipe 16 and from the partition wall 17 through the outdoor outlet cover 18. To release.

[0048] The outlet cover 118 includes a refrigerant pipe 20 that pipe-connects the indoor heat exchanger of the indoor unit 1 and the outdoor heat exchange of the outdoor unit, the exhaust pipe 16, the wiring and drain of the filter cleaning device 5. It is attached so as to cover the outside of the through hole 22 formed in the partition wall 17 so as to pass a hose or the like.

[0049] The outlet cover 18 is a cover body 123 that is semi-cylindrical and includes an L-shape in a side view including the refrigerant pipe 20, the exhaust pipe 16, and the like, and is disposed closer to the outdoor wall than the cover body. Front cover 124 for attaching the main body 123 to the outdoor wall, an opening / closing valve device 126 detachably attached to the opening 125 formed on the extended line of the exhaust pipe 16 at the corner of the cover main body 123, and the opening An exhaust cover 128 that covers 125 and includes an exhaust path 27 is provided, and the exhaust cover 128 is detachably attached to the cover body 123 with screws.

[0050] As shown in FIG. 9, the opening 125 is formed with a lattice portion 130 in which a large number of insect repellent slits 129 are formed. The rear end of the exhaust pipe 16 is brought into contact with the grid portion 130. Then, dust in the exhaust may adhere and block the lattice portion 130. Therefore, an opening / closing valve device 126 for repelling insects is required instead of the lattice portion 130.

[0051] This on-off valve device 126 inserts a cutter around the lattice portion 130 to cut out the lattice portion 130, or beats it with a screwdriver or the like to remove the lattice portion 130, and opens and closes the opening portion 125 to the removed opening portion 125. Install device 126. In FIG. 10, a concave cut groove 131 may be formed around the lattice portion 130 to facilitate removal of the lattice portion 130.

[0052] The on-off valve device 126 has a support frame 133 as a device main body fitted and screwed to the peripheral wall of the opening 125, and an upper end of the support frame 133 is opened and closed around the support shaft 134. It consists of an open / close valve 135 that is freely supported.

[0053] The opening 125 is formed in a substantially square shape, and a screw hole 136 is formed at the center of each side. The on-off valve device 126 is screwed and fixed together with the exhaust cover 128 using the screw hole 136.

[0054] The support frame 133 is formed in a square frame shape, and a central portion of each side thereof is formed with a cut recess 137 so as to be able to pass through the screw. I am able to do it. Therefore, as shown in Fig. 13, even when the outlet cover 118 is rotated 90 degrees and used in the horizontal position, the on-off valve device 126 is rotated 90 degrees so that the support shaft 134 is always in a horizontal state. can do. The support frame 133 is provided with a mark 141 indicating the mounting direction of the on-off valve device.

The on-off valve 135 is pivotally supported at its upper end so as to be rotatable around the support shaft 134, and closes due to its own weight when the filter cleaning device 5 is stopped, and is generated in the exhaust pipe 16 when the filter cleaning device 5 is in operation. It is supported by the support frame 133 so as to be opened by the exhaust pressure. The rear end of the exhaust pipe 16 is in contact with the indoor side of the on-off valve 135.

[0056] In the above configuration, when the exhaust pipe 16 of the filter cleaning device 5 is enclosed in the outlet cover 118, since the air exhausted from the exhaust pipe 16 contains dust, as shown in FIG. When there is a lattice portion 130 formed with a number of insect repellent slits 129 formed in 118, dust in the exhaust gas may adhere to the lattice portion 130 and block the lattice portion 130. Therefore, put a cutter around the grid part 130 to The on-off valve device 126 is attached to the removed opening 125 by excising. As a result, the on-off valve device 26 can also be installed in a relatively large space in the outlet cover 18, so that the mounting workability is improved.

[0057] In this case, the exhaust cover 128 force covering the opening 125 is attached to the cover body 123 of the outlet cover 118 so as to be detachably attached to the S cover body 123. Therefore, the grid portion is removed with the exhaust cover 128 removed. 130 is removed, and then the on-off valve device 126 is also fitted with an external force. If the exhaust cover 128 is fixed to the cover main body 123 with screws or the like, its mounting workability is greatly improved.

[0058] At this time, the on-off valve device 126 is set so that the on-off valve 135 is closed by its own weight when the filter cleaning device 5 is not operating, and is opened by the exhaust pressure generated in the exhaust pipe 16 during operation. Therefore, the outdoor force can also prevent insects from entering the room through the exhaust pipe 16.

Further, as shown in FIG. 13, when the cover body 123 is placed in a horizontal position with respect to the outdoor wall, the on-off valve device 126 is arranged with respect to the opening 125 so that the support shaft 134 is always in a horizontal state. It can be installed by rotating 90 degrees.

[0060] For this reason, the outlet cover 118 can be set either vertically or horizontally depending on the installation status of the outdoor unit. At this time, the on-off valve device 126 can be installed vertically or horizontally. Both can be accommodated.

[0061] In the above embodiment, a grid-like filter that removes large dust may be provided on the upstream side of the suction fan 12, so that large dust can be removed and only fine dust can be removed. Let ’s drain it out of the room.
