Abstract

(57) [Summary] [Purpose] To obtain an air conditioner equipped with a drain hose connection part that is easy to attach and detach. [Structure] A base 1 on which a fan 3 and a heat exchanger 4 are attached is covered with a cover 2, and a dew pan 5 is provided below the heat exchanger 4. The drain hose 6 connected to the rear of the bottom is
A cylindrical body 8 having a spiral flange 8a on its outer periphery is provided at its tip, and is inserted through a narrow part 7a provided in a notch 7 at the bottom of the base 1.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an air conditioner, and more particularly to a drain hose holding structure.

0002

[Conventional technology]

In conventional air conditioners, the base on which the fan and heat exchanger are mounted is covered with a cover. , connect the drain hose to the dew pan placed below the heat exchanger, and use a locking device such as a band. After preventing it from coming off, it was guided to the rear of the aircraft through the notch at the bottom of the base.

0003

[Problem that the idea aims to solve]

However, if it is necessary to remove the drain hose for maintenance, inspection, or repair, etc. To do so, first remove the cover, then remove the screws securing it to the base and remove the condensation pan. This is because the drain hose cannot be removed unless it is removed and the locking device is loosened. The drawback was that these tasks were time consuming.

0004

[Means to solve the problem]

In order to solve the above problems, in this invention we installed a fan and a heat exchanger. Cover the base with a cover, place a dew pan below the heat exchanger, and connect it to the dew pan. In an air conditioner where the drain hose is led out from the notch at the bottom of the base. , a spiral flange is provided on the outer periphery of the drain hose, and a dowel is provided in the notch of the base. A narrow part is provided that is approximately equal to the outer diameter of the drain hose, and the drain hose between the collar parts is installed in the narrow part. An air conditioner characterized by being locked.

[0005]

[Effect]

It can be attached and detached by rotating the tip of the drain hose and prevents it from falling off. has been done.

[0006]

【Example】 Embodiments of the air conditioner according to the present invention will be described below with reference to FIGS. 1 to 3. Figure 1 is a cross-sectional view of this air conditioner, showing the base 1 with the fan 3 and heat exchanger 4 attached. The heat exchanger 4 is covered with a bar 2, and a dew pan 5 is disposed below the heat exchanger 4, and a door is placed behind the bottom of the tray 5. The Len hose 6 is connected and guided from the notch 7 at the bottom of the base 1 to the rear of the aircraft. Ru. FIG. 2 is a side view of the connection part, and the lower half shows a cross section. Also, FIG. 3 shows A- in FIG. It is a view from arrow A. As shown in both figures, the drain hose 6 has a cylindrical body 8 at its tip. and is connected to the drain pipe 5a of the dew pan 5. This cylindrical body 8 is made of synthetic wood, for example. The side connected to the drain hose 6 is formed into a double cylinder with a shortened outer side. A hose is inserted in between and fixed with adhesive, or it is pressed and fixed to the inner cylinder with a band, etc. . In addition, the side connected to the drain pipe 5a has an inner cylinder with a slot to give it elasticity and a spiral. It is formed into a double cylinder with an outer cylinder having a shaped flange 8a on the outer periphery. On the other hand, below base 1 A pair of protruding pieces 1a are provided on the left and right sides of the notch 7 provided in the part to form a narrow part 7a. ing. The width of this narrow part 7a is smaller than the diameter of the collar part 8a and larger than the outer diameter of the outer cylinder. .

[0007] Therefore, when assembling, the cylindrical body 8 is fixed to the drain hose 6, and the drain pipe is attached to this. 5a and then move the cylindrical body 8 between the flanges 8a within the notch 7 to remove the condensation pan 5. Push up to secure it to base 1, and cover with cover 2. When performing maintenance or inspection, When the shaped body 8 is rotated counterclockwise when viewed from the back, the flange 8a has a narrow part that serves to prevent it from falling off. The inner cylinder comes off from the drain pipe 5a at the same time as it comes off from the neck 7a. Installation is done in reverse order. That's fine.

In the above embodiment, the cylindrical body 8 is provided and the drain hose 6 is connected to it. However, it is also possible to mold these into one piece.

[0009]

[Effect of the idea]

A spiral flange is provided on the drain hose, and a narrow portion is provided in the notch in the base. Therefore, it is possible to achieve the effect of facilitating attachment and detachment after installation.
