Abstract

PROBLEM TO BE SOLVED: To difficultly generate crazing in a drain port even when the oil is mixed in a drain hose, and the load is applied to the drain port by providing a supporting part on a drain pan having the drain port which is integratedly and projectingly formed of the synthetic resin, and supporting the drain hose by the supporting part so as to be connected to the drain port. SOLUTION: A synthetic resin drain pan 2 is arranged on a lower part of a heat exchanger 1, and a cylindrical drain port 3 is integratedly and projectingly formed with a part of the drain pan 2 to project an outer cylinder 4 concentric with the drain port 3 on the outer side of the drain port 3. An outer circumferential part of a drain hose 5 is fitted to the outer cylinder 4, while an inner circumferential part of the drain hose 5 is loosely fitted to the drain port 3, and the drain hose 5 is supported by the outer cylinder 4. That means, the outer cylinder 4 is a supporting part of the drain hose 5. Even when oil, etc., is mixed in the drain hose 5, and the load is applied to the drain port 3, crazing is difficult to generate in the drain port 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

According to a first aspect of the present invention, there is provided a drain hose connecting device, wherein a support is provided in a drain receiver having a drain port integrally formed of synthetic resin, and a drain is provided on the support. The hose is supported and connected to the drain port.

A drain hose connecting device according to a second aspect of the present invention is the drain hose connecting device according to the first aspect, wherein the support portion is an outer cylinder formed concentrically with the drain port, and the outer peripheral portion of the drain hose is fitted into the outer cylinder. And connected to the drain port.

A drain hose connection device according to a third aspect of the present invention is the drainage connection device according to the first aspect, wherein the support portion is formed of a member disposed around the drain port, and the inner peripheral portion of the drain hose is formed on this member. It is fitted and connected to the drain port.

A hose connecting device according to a fourth aspect of the present invention is characterized in that a support portion is provided in a fluid receiver having a fluid passage port integrally formed of synthetic resin and having a fluid passage port. Connected to.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. FIG. 1 is a sectional view of an essential part showing one embodiment of the first and second inventions of the present invention. In the figure, 1 is a heat exchanger of an air conditioner, 2 is a drain receiver made of a synthetic resin arranged at the lower part of the heat exchanger 1, and a cylindrical drain port 3 is formed integrally with the drain receiver 2 at a part thereof. An outer cylinder 4 is formed so as to protrude outside the drain port 3 and concentrically with the drain port 3. Reference numeral 5 denotes a drain hose fitted inside the outer cylinder 4.

In the drain hose connecting device configured as described above, the drain generated from the heat exchanger 1 is stored in the drain receiver 2 by the operation of the air conditioner.
Then, the drain flows down from the drain port 3 to the drain hose 5 and is discharged to the outside. At this time, the outer peripheral part of the drain hose 5 is fitted into the outer cylinder 4, the inner peripheral part of the drain hose 5 is loosely fitted into the drain port 3, and the drain hose 5 is supported by the outer cylinder 4. That is, the outer cylinder 4 serves as a support for the drain hose 5.

Therefore, when the drain flows through the drain hose 5, the load acting via the drain hose 5 is supported by the outer cylinder 4 and does not act on the drain port 3. Therefore, even when oil or the like is mixed in the drain, crazing hardly occurs in the drain port 3, and there is little possibility that the drain is broken.

Embodiment 2 FIG. FIG. 2 is a sectional view of a main part showing an embodiment of the third invention of the present invention. In this embodiment, instead of the outer cylinder 4 of the drain port 3 in FIG.
, A plurality of ridges 8 projecting from the drain receiver 2 are provided as support portions. The inner peripheral portion of the drain hose 5 is fitted into the ridge 8.

For this reason, the load acting via the drain hose 5 is supported by the ridge 8 and does not act on the drain port 3.
There is an effect similar to that of the first embodiment.

Embodiment 3 FIG. 3 is a sectional view of a main part showing another embodiment of the third invention of the present invention. In this embodiment, an outer cylinder 9 similar to the outer cylinder 4 of the drain port 3 in FIG. 1 is provided as a support portion, and the drain hose 5 has an inner peripheral portion fitted into the outer cylinder 9. There is an effect similar to that of the second embodiment.

Embodiment 4 An embodiment of the fourth invention of the present invention is shown. In each of the above embodiments, the form applied to the drain port 3 of the air conditioner has been described. However, the present invention is not limited to this, and the connection portion such as a hose is formed of a synthetic resin.
The present invention is widely applicable to those in which this connection portion contacts oil and a load acts. That is, the outer cylinder 4, the ridge 8 or the outer cylinder 9 is provided in a configuration having a fluid receiver corresponding to the drain receiver 2, a fluid passage port corresponding to the drain port 3, and a hose corresponding to the drain hose 5. By adding the same, the same effects as in the above embodiments can be expected.

[0017]

As described above, according to the first aspect of the present invention, a supporting portion is provided on a drain receiver having a drain port integrally formed of synthetic resin, and a drain hose is supported by the supporting section to form a drain port. Connected, the drain hose is supported by the support section, and even if a load acts on the drain hose,
It does not act on the drain port, and even when oil or the like is mixed in the drain, crazing hardly occurs in the drain port, and the possibility of breakage of the drain port can be reduced.

In the second invention, the supporting portion is an outer cylinder formed concentrically with the drain port, and the outer peripheral portion of the drain hose is fitted into this outer cylinder and connected to the drain port. effective.

In the third aspect, the support portion is formed by a member arranged around the drain port, and the inner peripheral portion of the drain hose is fitted into this member and connected to the drain port. Has the effect.

According to the fourth aspect of the present invention, the fluid receiver having the fluid passage formed integrally with the synthetic resin is provided with the support, and the hose is supported by the support and connected to the passage. It has the same effect as the invention and can be widely applied to hoses that come into contact with oil.
