Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to air conditioners, and more specifically to the maintenance of the bell mouth of ceiling-mounted air conditioners. Regarding the holding structure.

0002

[Conventional technology]

Referring to Fig. 5 together with Fig. 1, the conventional ceiling-embedded air conditioner is open at the bottom. A fan 2 and a heat exchanger 3 surrounding the fan 2 are arranged inside the box-shaped main body 1, and the same heat exchange is performed. The open surface in contact with the lower surface of the container 3 is covered with a shielding member 4, and the fan 2 is attached to the shielding member 4. An inlet 5 is provided facing the main body 1, and an outlet 6 is provided between the inlet and the main body 1. 5 is covered with a bell mouth 7, one end is fixed to the lower end of the main body 1, and the other end is supported on a support rod 8. While pressing the shielding member 4 against the heat exchanger 3 by the four supported plates 9, The bell mouth 7 is fixed to the support plate 9 from below with screws.

0003

[Problem that the idea aims to solve]

However, when removing the bell mouth for maintenance, inspection, or repair, the last The bell mouth will fall the moment you remove the screw, so two people are required to do the work. If you are doing this alone, hold the bell mouth with one hand and remove the screw with the other hand. Therefore, it is easy to lose the rabbit-angle screws, and it takes extra time to find them, which increases the work time. This had the disadvantage of increasing construction costs.

0004

[Means to solve the problem]

In order to solve the above problem, this invention has a box-like main body with an open bottom. A fan and a heat exchanger surrounding it are installed in the is covered with a shielding member, and the shielding member is provided with an inlet facing the fan, and An air conditioner in which a discharge port is provided between the main body and the inlet port is covered with a bell mouth. Then, a support member is provided to hold the shielding member from below, and a bell mouth is fixed to this support member. and a clamping part for clamping the peripheral edge of the bell mouth on the support body. It is characterized by.

[0005]

[Effect]

Even if all the screws are removed, one end of the bell mouth will be held by the support plate and will not fall.

[0006]

【Example】

Embodiments of the air conditioner according to the present invention will be described below with reference to FIGS. 1 to 4. Figure 1 is a cross-sectional view of this air conditioner, Figure 2 is its bottom view, and Figure 1 shows the A-A cross section in Figure 2. represents. As shown in the figure, there is a fan in the center of the box-shaped main body 1 that is open at the bottom. A heat exchanger 3 is also suspended surrounding it. isothermal exchange A shielding member 4 that is in contact with the lower surface of the container 3 and also serves as a condensation pan faces the fan 2 and opens an inlet 5. A discharge port 6 is provided between the main body 1 and the open surface thereof. And this suction The entrance 5 is covered with a bell mouth 7. Figure 3 is an enlarged bottom view of the main parts, and Referring to FIG. 4, which is a B-B arrow view of FIG. The support rod 8 is fixed to the main body 1 and the other end is fixed to the main body 1 and is provided at the lower end of the hanging support rod 8. The heat exchanger 3 is pressed from below by four support plates 9 fixed to the screws with nuts. Ru. One of the support plates 9 is provided with a clamping part that clamps the peripheral edge of the bell mouth 7. ing. That is, as shown in FIG. 3, the tip is divided into two parts, a flat plate 9a and a bent plate 9b, and A screw hole for fixing the bell mouth 7 is drilled in the plate 9a, and a bent plate 9b is inserted. is bent downward once, and then the flat plate 9a is placed again with a gap greater than the thickness of the bell mouth 7. It is bent so that it is parallel to the

[0007] Therefore, when removing the bell mouth 7, the screws on the support plate 9, which do not have the shape shown in FIG. After removing the book and finally removing the screws on the support plate 9 shown in Figure 3, the area around the bell mouth can be seen. The edge is supported at the back of the lower surface of the flat plate 9a and the tip of the bent plate 9b, as shown by the two-dot chain line in Fig. 4. It is held tilted without falling off. Now remove the screw and use the bell mouth. Remove. When installing in the opposite direction, align the periphery of the bell mouth 7 with the above flat plate 9a. If it is inserted into the clamping part formed by the bending plate 9b, it will be held at an angle, so it can be secured with screws. Then fix the remaining three.

[0008] In the above embodiment, the holding part is composed of one flat plate and one bent plate. However, if bent plates are provided on both sides of the flat plate, the bell mouth will be held more securely. or, The support plate uses multiple strips, but these are connected to form a ring. A clamping portion may be provided inside. In addition, the part where the bell mouth is held is a recess. However, it can be omitted by design.

[0009]

[Effect of the idea]

A clamping part is provided on the support plate to clamp the bell mouth, so when removing it, remove the last screw. The bell mouth will not fall even if the bell mouth is removed, so it can be easily worked by one person. Therefore, it is possible to have the effect of reducing construction costs. At the same time when installing It also has the effect of shortening the installation time since there is no need to hold it with one hand.
