Description

[Detailed description of the invention] This invention relates to an improvement of a water tray installed in an air conditioner.It prevents condensed water from leaking due to rust on the hose connection pipe, and ensures that condensed water is guided to the drain hose. The purpose of this is to make it easier to understand.

In general, when an air conditioner is built into an electric heater, etc., a steel plate is used for the water tray in consideration of the rise in temperature of the heater. A straight hose connection pipe is fixed to lead the condensed water collected in the saucer to the outside.

In this type of conventional water tray structure, as shown in Fig. 4, a metal hose connection pipe b is fixed to the water tray main body a, but the connection part c is welded in order to prevent condensed water from leaking. are doing. Moreover, the welding is performed to prevent condensed water from leaking outside from the connection part c between the water pan a and the straight pipe b, and to provide sufficient strength for the connection of the drainage connection hose, etc.
The entire circumference is welded. However, it is very difficult to perform welding reliably so that there are no holes in the connection part c that could lead to water leakage. In addition, since the drain port d provided in the water pan body a and the connection part c between the water pan body a and the hose connection pipe b are almost on the same plane, condensed water will not enter the connection part c, which is the welded part. This easily led to rust, which led to corrosion of the connection part c, which caused water leakage, etc.

The present invention solves the above-mentioned conventional drawbacks, and an embodiment thereof will be described below with reference to FIGS. 1 to 3 of the accompanying drawings. Figure 1 shows a schematic configuration of an indoor unit of a separate type air conditioner. 1 is the air conditioner main body, inside of which are a suction port 2, a fan 3, a casing 4 housing the fan 3, and An evaporator 5 that constitutes a well-known refrigeration cycle, and an outlet 6 that blows out cold air from the evaporator 5
A ventilation circuit is provided. Reference numeral 7 denotes a water tray made of iron plate provided at the lower part of the evaporator 4, and a hose connection pipe 8 is attached to the bottom surface of the tray for guiding accumulated condensed water to the outside.

FIGS. 2 and 3 show the structure of the water tray 7. A cylindrical drain port 7c having a drain port 7b and projecting downward is provided on the bottom surface of the water tray main body 7a. Further, a curled portion 7d is provided continuously to this drain port portion 7c. This curl part 7
The tip of d is located above the lower end 7c' of the drain port 7c and outside of the drain port 7c. A hose connection pipe 8 is press-fitted onto the outer periphery of the curled portion 7d so as to wrap around the curled portion 7d.

In the above configuration, the condensed water accumulated in the water tray 7 reaches the hose connection pipe 8 from the drain port 7b via the drain port portion 7c. Here, the water is discharged to an appropriate position via a drain hose (not shown) attached as necessary. At this time, the drain port 7c and the hose connection pipe 8
An appropriate space is formed between the curled portions 7d (the tip of the curled portions 7d is connected to the drain port 7c).
), this condensed water does not enter the contact portion 7e between the inner surface of the hose connection pipe 8 and the curled portion 7d. As a result, the problem of corrosion of the contact portion 7e between the hose connection pipe 8 and the water receiving tray 7 due to the intrusion of condensed water can be solved, and accidents such as water leakage can be prevented. Furthermore, since the contact portion 7e between the water tray 7 and the hose connection pipe 8 does not require airtightness to prevent leakage of condensed water, it is not necessary to ensure secure contact over the entire circumference. It is sufficient to have the strength necessary to attach the holder, and the press-fitting work becomes easy.

Note that the water tray 7 is not limited to an iron plate, and can also be made of aluminum or the like.

As is clear from the above description, the present invention provides a cylindrical drainage port having a drainage port on the bottom surface of the water tray main body, and also provides a curled portion continuous to this drainage port, and the outer circumference of this curled portion. Since the hose connection pipe is press-fitted into the drain port, water from the drain port does not enter the contact area between the water tray and the hose connection pipe, thereby preventing rust from forming. In addition, there is no need to join by welding, making installation and manufacturing easy, and there is no need to paint after welding, making the cost extremely low. Furthermore, synthetic resin can be used for the hose connection pipe, and press-fitting work can be made easier.
