Description

The present invention relates to a support member and a blower attached to a ceiling material having an opening.

As disclosed in Patent Document 1, there is a blower device including a main body provided above the ceiling material in which an opening is formed, so-called attic, and a decorative panel covering the opening. In such a blower, a blower provided in the main body generates an air supply from the outside to the room and an exhaust flow from the room to the outside. The air supply generated by the main body supplies the outdoor air to the room through the air supply port formed in the decorative panel. Due to the exhaust flow generated by the main body, indoor air is sucked in from the return air port formed in the decorative panel and exhausted to the outside.

When the blower is a heat exchange ventilation device that exchanges heat between the air supply and the exhaust flow, a heat exchange element is provided inside the main body.

Japanese Patent No. 5174949

The main body of the heat exchange ventilator is provided with a blower, a heat exchanger, and a control board. Therefore, the projected area in the vertical direction may be larger than that of the decorative panel. In this case, the main body cannot be pulled out from the ceiling with an opening formed so large that it can be covered with a decorative panel. Therefore, when replacing the main body provided behind the ceiling, it is necessary to enlarge the opening formed in the ceiling material to move the main body in and out. If the opening is enlarged, it will be necessary to perform troublesome restoration work to close the opening after replacing the main body, or the ceiling material used for the widened opening will be scrapped and it will be necessary to dispose of it. The cost of replacement work tends to increase.

A blower device such as a heat exchange ventilation device has a problem that the cost of the above-mentioned replacement work is avoided and it is difficult to update the device as compared with other facilities. Therefore, the use of the blower having low energy saving performance is continued, or the blower is left in a broken state.

The present invention has been made in view of the above, and it is possible to facilitate the restoration of the opening widened when the main body of the blower provided in the ceiling is renewed and to suppress the generation of waste materials. The purpose is to obtain a support member.

In order to solve the above-mentioned problems and achieve the object, the present invention includes a first portion that comes into contact with the ceiling material, a second portion that extends from one end of the first portion, and a first portion. A first member having a third portion protruding from the boundary of the second portion, a fourth portion sandwiching the ceiling material between the first portion, and a fourth portion are the first. A second member having a fifth portion into which the third portion is inserted with the ceiling material sandwiched between the portions is provided. The second portion has a mounting surface on which a ceiling material different from the ceiling material sandwiched between the first portion and the fourth portion can be placed.

According to the support member according to the present invention, it is possible to facilitate the restoration of the widened opening when the main body of the blower device provided in the ceiling is renewed and to suppress the generation of waste materials.

The heat exchange ventilator 20 described above is assumed to be in a state after the existing heat exchange ventilator is replaced. Next, the procedure for replacing the existing heat exchange ventilator with the heat exchange ventilator 20 will be described above. FIG. 5 is a flowchart illustrating a procedure for replacing the heat exchange ventilator according to the first embodiment. FIG. 6 is a cross-sectional view showing the installation state of the existing heat exchange ventilation device. FIG. 7 is an arrow view taken along the arrow VII shown in FIG. FIG. 8 is a cross-sectional view showing a process of replacing an existing heat exchange ventilation device. FIG. 9 is a cross-sectional view taken along the line IX-IX shown in FIG.

The existing heat exchange ventilator 120 includes a main body 121 and a decorative panel 122, similarly to the heat exchange ventilator 20. Note that in FIG. 6, hatching to the main body 121 and the decorative panel 122 is omitted. Since the configurations of the main body 121 and the decorative panel 122 are almost the same as those of the main body 1 and the decorative panel 2, detailed description thereof will be omitted. In the existing heat exchange ventilation device 120, the main body 121 is installed before the ceiling material 8 is provided. As shown in FIGS. 6 and 7, the ceiling material 8 is formed with a third opening 16 having a size that can be closed by the decorative panel 122. Therefore, the size of the third opening 16 is insufficient, and the main body 121 cannot be pulled out from the ceiling as it is.

Therefore, as shown in FIGS. 8 and 9, the ceiling material 8 around the third opening 16 is cut off to form a second opening 15 from which the main body 121 can be pulled out (step S1). The ceiling material 8 cut off at this time becomes the second ceiling material 8b and the third ceiling material 8c. Further, the ceiling material 8 that remains without being cut off becomes the first ceiling material 8a.

Next, the main body 121 is pulled out from the ceiling through the second opening 15 (step S2). Next, the main body 1 of the heat exchange ventilation device 20 is installed behind the ceiling through the second opening 15 (step S3). Next, the support member 21 is fixed to the opening edge of the second opening 15 (step S4). Next, as shown in FIGS. 1 and 3, the second ceiling material 8b and the third ceiling material 8c are placed on the mounting surface 42a of the support member 21 (step S5). As a result, a first opening 14 having a size that can be closed by the decorative panel 2 is formed.

Next, the first opening 14 is closed by the decorative panel 2, and the decorative panel 2 and the main body 1 are connected by the connecting member 9, and the replacement with the heat exchange ventilation device 20 is completed (step S6). When the first opening 14 is closed by the decorative panel 2, the portion of the second ceiling material 8b and the third ceiling material 8c along the opening edge of the first opening 14 becomes the decorative panel 2. Be supported.

As described above, according to the heat exchange ventilator 20 according to the first embodiment, the third opening 16 formed in the ceiling material 8 is widened in order to replace the existing heat exchange ventilator 120. Even if the second opening 15 is formed, the restoration work can be completed by fixing the support member 21 and mounting the second ceiling material 8b and the third ceiling material 8c on the mounting surface 42a. Therefore, the restoration of the second opening 15 can be facilitated. Further, the second ceiling material 8b and the third ceiling material 8c that close the second opening 15 are ceiling materials 8 that are cut off when the third opening 16 is widened and become waste material. In the first embodiment, since the second ceiling material 8b and the third ceiling material 8c, which are waste materials, are reused to close the second opening 15, it is possible to suppress the generation of waste materials.

Therefore, the cost of the replacement work of the heat exchange ventilation device 20 can be suppressed. If the cost of the replacement work of the heat exchange ventilator 20 is suppressed, it will be easier to replace the heat exchange ventilator 20 with a heat exchange ventilator having excellent energy saving performance. In addition, since the heat exchange ventilation device is less likely to be left in a broken state, it is possible to prevent the living environment from being deteriorated due to insufficient ventilation.

Further, if the support member 21 is cut and the length is adjusted, the support member 21 can be fixed to the first ceiling material 8a according to the size of the second opening 15 at the site where the replacement work is performed. .. Therefore, since it is not necessary to prepare the support members 21 having different lengths in advance, the cost of the replacement work can be suppressed from the viewpoint of inventory.

Although the heat exchange ventilation device has been described as an example of the blower, the present invention is not limited to this. If the main body arranged behind the ceiling is a blower device larger than the opening closed by the decorative panel, it may be a blower device that only exhausts air or a blower device that only supplies air. .. Further, a blower device that supplies and exhausts air but does not exchange heat may be used. Further, the blower may be an air conditioner.

The configuration shown in the above-described embodiment shows an example of the content of the present invention, can be combined with another known technique, and is one of the configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
