Description

The present invention relates to an attitude holding device that holds the posture of a chamber with respect to the main body of an air conditioner in an air conditioner in which a chamber such as a blowout chamber is attached to the end of the main body of the air conditioner.

Conventionally, an air conditioner installed in a state of being concealed in a ceiling space is known (for example, Patent Document 1). This type of air conditioner includes an air conditioner body supported by a hanging bolt or the like hanging from a ceiling structure such as a ceiling slab, and a blower mounted on one side surface of the air conditioner body. Some are equipped with a chamber. For example, the main body of the air conditioner has an outlet sleeve having a peripheral portion of the outlet protruding, and the outlet chamber is provided with a connection sleeve attached to the outlet sleeve. The blowout chamber is integrally mounted with respect to the side surface of the air conditioner body by fitting the connecting sleeve inside or outside the blowout sleeve.

When the air conditioner starts operation, the fan provided inside the air conditioner main body operates, so that the air-conditioned air is blown out from the outlet to the outlet chamber. Since the wind pressure blown out from the air conditioner body is high, a large number of screws are struck in the circumferential direction at the part where the blowout sleeve and the connection sleeve overlap, and the blowout chamber is fixed so as not to separate from the air conditioner body. To.

However, simply supporting the blowout chamber with a large number of screws struck on the connecting sleeve causes the end of the blowout chamber to hang down due to its weight. In order to prevent this, conventionally, as in the case of the main body of the air conditioner, the end of the blow chamber is supported by attaching a hanging bolt or the like to the side surface or the end of the blow chamber to support the blow chamber in a suspended state. It prevents it from hanging down and maintains an appropriate posture with respect to the main body of the air conditioner.

However, the structure in which the blowout chamber is supported by a hanging bolt or the like has the following problems.

First, when installing the suspension bolts that support the blowout chamber in a ceiling structure such as a ceiling slab, it is necessary to install anchors in the ceiling structure and attach the suspension bolts. At this time, it is necessary to install the anchor at an appropriate position according to the size of the blowout chamber and the installation position of the blowout chamber in the ceiling space, resulting in poor work efficiency. Further, the work of installing the anchor and the work of attaching the hanging bolt to the anchor have a problem that the work efficiency is poor because the work is performed at a high place.

Second, the air conditioner main body may be equipped with an intake chamber in addition to the outlet chamber. The intake chamber is attached to the side surface of the air conditioner body opposite to the side surface to which the outlet chamber is attached. In this case, the intake chamber is also supported in a suspended state by a suspension bolt or the like in the same manner as the blowout chamber in order to prevent the end portion from being in a hanging state. When the blowout chamber and the intake chamber are mounted on the air conditioner main body, it is preferable that both the blowout chamber and the intake chamber are mounted in a substantially horizontal state with respect to the air conditioner main body. However, in order to adapt the postures of the blowout chamber and the intake chamber to the main body of the air conditioner, the postures of the blowout chamber and the intake chamber must be adjusted individually. Therefore, there is a problem that the work efficiency is particularly lowered when the outlet chamber and the intake chamber are attached to the main body of the air conditioner.

Thirdly, when the outlet chamber is supported by the suspension bolts, the suspension bolts are installed between the ceiling structure and the outlet chamber, and the space between the ceiling structure and the outlet chamber can be effectively utilized. Can not. Therefore, there is a problem that various pipes and the like cannot be arranged in the space above the blowout chamber.

Fourth, a duct connection portion for connecting a duct such as a flexible duct is provided on the side surface of the blowout chamber. If a hanging bolt is attached near the duct connection portion, the hanging bolt becomes an obstacle when attaching the duct to the duct connection portion. In order to prevent this, it is regulated to attach the suspension bolt to the position near the duct connection portion, and the position to attach the suspension bolt is restricted. Therefore, when attaching the suspension bolt to the blowout chamber, the suspension bolt must be attached so as to avoid the vicinity of the duct connection portion, and there is a problem that the work efficiency is poor.

The end surface 120b) on the side opposite to the surface attached to the machine body 110 hangs down and is in an inclined state. Similarly, when the intake chamber 130 is cantilevered to the connection portion 114 of the air conditioner main body 110, the end portion of the intake chamber 130 (that is, the side opposite to the surface attached to the air conditioner main body 110) is attached. The end face 130b) hangs down and is in an inclined state. That is, although the blowout chamber 120 and the intake chamber 130 are lightweight, if they are attached to the air conditioner main body 110 in a cantilevered state, they will hang down due to their own weight.

When the ends of the outlet chamber 120 and the intake chamber 130 hang down, stress concentrates on the lower parts P of the connection portions 113 and 114, and at the lower parts P of the connection portions 113 and 114, the air conditioner main body 110, the outlet chamber 120 and the intake chamber There is a possibility of causing damage such as dents and cracks on the wall surface of the 130. In order to prevent such damage, the posture holding device 1 holds the blowout chamber 120 and the intake chamber 130 so that their respective postures are substantially parallel to the air conditioner main body 110.

In the posture holding device 1, first, as shown in FIG. 6A, the first engaging member 2 is attached to the upper portion of the end surface 120b of the blowing chamber 120 by using a screw 6, and the second engaging member 3 is attached to the intake chamber. It is attached to the upper part of the end surface 130b of 130 by using a screw 6. Then, one end 4a of the connecting portion 4 composed of bolts is inserted into the hole 14 of the first engaging member 2 to mount the nut 5 at the tip, and the other end 4b of the connecting portion 4 is attached to the second engaging member 3. A nut 5 is attached to the tip of the hole 24 through the hole 24. When the nuts 5 and 5 attached to both ends of the connecting portion 4 are not tightened, the ends of the blowout chamber 120 and the intake chamber 130 are still in a hanging state as shown in FIG. 6A. be.

As shown in FIG. 6A, when the posture holding device 1 is attached to the air conditioner 100, the operator attaches the blowout chamber 120 and the intake chamber 130 mounted on both ends of the connecting portion 4, and the connecting portion. Tighten the nut 5 in the axial direction of 4. When one of the two nuts 5, 5 is tightened, the distance between the two nuts 5, 5 is gradually reduced. Along with this, the connecting portion 4 pulls the first engaging member 2 and the second engaging member 3 between the first engaging member 2 and the second engaging member 3 attached to both ends. Tension F1 is generated. This tension F1 acts as a force for lifting the end face 120b of the blowout chamber 120 and the end face 130b of the intake chamber 130. Therefore, as shown in FIG. 6B, the operator tightens one of the two nuts 5 and 5 to adjust the postures of both the outlet chamber 120 and the intake chamber 130 to the air conditioner main body. It can be adjusted to be substantially parallel to 110. When the postures of the blowout chamber 120 and the intake chamber 130 are substantially parallel to the air conditioner main body 110, the work is completed by completing the tightening of one of the nuts 5. As a result, the posture holding device 1 holds the postures of the blowout chamber 120 and the intake chamber 130 in a state substantially parallel to the air conditioner main body 110.

When performing the posture adjustment work as described above, the operator adjusts the line-of-sight position to the upper surface position of the air conditioner main body 110 and tightens one of the nuts 5, so that both the blowout chamber 120 and the intake chamber 130 are tightened. It is possible to easily recognize a state in which the upper surface of the air conditioner is substantially parallel to the upper surface of the air conditioner main body 110. Therefore, there is an advantage that the operator can easily visually adjust the postures of both the blowout chamber 120 and the intake chamber 130 so as to be substantially parallel to the air conditioner main body 110.

Further, when adjusting the postures of both the outlet chamber 120 and the intake chamber 130 so as to be substantially parallel to the air conditioner main body 110, the operator does not need to individually adjust the outlet chamber 120 and the intake chamber 130. By tightening one of the two nuts 5 and 5, it is possible to adjust both the outlet chamber 120 and the intake chamber 130 at the same time, which is excellent in work efficiency. Therefore, when the posture adjustment work as described above is performed at a high place in a state where the air conditioner 100 is suspended from the ceiling space by the suspension bolt 101, the work can be efficiently performed.

Further, the posture adjusting work as described above can also be performed as a floor surface work on the floor surface before the air conditioner 100 is suspended by the suspension bolt 101. When the work is performed on the floor, the work efficiency can be further improved as compared with the work at a high place. In particular, on the floor surface, the blowout chamber 120 and the intake chamber 130 are assembled to the air conditioner main body 110, and the postures of the blowout chamber 120 and the intake chamber 130 are adjusted in advance so as to be substantially parallel to the air conditioner main body 110. Therefore, when the air conditioner 100 is installed in the ceiling space, it is not necessary to attach hanging bolts 101 to each of the blowout chamber 120 and the intake chamber 130. That is, if four suspension bolts 101 are connected to the connection pieces 112 and 112 provided on both the left and right sides of the air conditioner main body 110, the air conditioner 100 can be installed in the ceiling space. It is not necessary to attach the suspension bolt 101 to each of the blowout chamber 120 and the intake chamber 130, which are lighter than the air conditioner main body 110. Therefore, it is possible to save labor for installing the suspension bolt 101 in a ceiling structure such as a ceiling slab.

For example, when performing posture adjustment work on the floor surface work, as shown in FIG. 6B, after adjusting the postures of the blowout chamber 120 and the intake chamber 130 with respect to the air conditioner main body 110, the elevator or the like is moved. The air conditioner 100 is lifted to a position near the ceiling structure using the air conditioner 100, and the air conditioner 100 is connected to the connection pieces 112 provided on the left and right sides of the air conditioner main body 110 by connecting the suspension bolts 101 to the ceiling space. Can be installed in.

However, even when the postures of the blowout chamber 120 and the intake chamber 130 are adjusted by using the posture holding device 1 of the present embodiment, the suspension bolts 101 are further attached to each of the blowout chamber 120 and the intake chamber 130. You may adopt the method.

By the way, when the tension F1 generated in the connecting portion 4 excessively pulls the first engaging member 2 and the second engaging member 3 in the posture adjusting work as described above, this time, the upper part of the connecting portions 113 and 114 is subjected to. Stress is concentrated, and there is a possibility that the wall surfaces of the air conditioner main body 110, the blowout chamber 120, and the intake chamber 130 may be damaged such as dents and cracks in the upper part of the connection portions 113 and 114. Therefore, if one of the two nuts 5 and 5 is overtightened, construction failure may occur. In order to prevent the occurrence of such construction defects, it is preferable to arrange the spacer 30 above the connecting portions 113 and 114 as shown in FIG.
