Abstract

PROBLEM TO BE SOLVED: To prevent adhesion of dust onto a covered port in a removed state and to prevent dust from entering an end connection at reattachment by providing a protective member, to which a cap is removably attached, for protecting the covered part against the end connection of the cap in a attached state. SOLUTION: A protective member 33 is formed to which a removed cap 7 at use of end connections 41 and 42 can be removably attached and which protects protruding parts 71 and 72 of the cap 7 in a attached state is formed on the inner face of a lid 3c. This protective member 33 is formed in the size that an O ring is in close contact with it on both ends in the horizontal direction in the state where the protruding parts 71 and 72 are fitted into. If the cap 7 is attached when the end connections 41 and 42 are not used, the protruding parts 71 and 72 are fitted into the end connections 41 and 42 in the water-tight state, and by this, intrusion of dust into the end connections 41 and 42 can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water outlet, and more particularly, to a hot water outlet which is attached to an indoor side wall so as to cover a wall hole and has a pair of connection ports.

[0002]

2. Description of the Related Art FIG. 10 is an explanatory view when a connection port (93) in a conventional hot water heating apparatus (9) is used, and FIG. 11 is a view when the connection port (93) in FIG. 10 is not used. FIG. As shown in FIG. 10, the hot water heating device (9) includes an outdoor unit (9a) for heating hot water outdoors and an indoor unit (9b) for releasing heat of the heated hot water indoors. , The partition wall between the outside and the room (9
And a hot water outlet (9c) mounted on the indoor side wall so as to cover the wall hole (90a) of (0).

[0003] The hot water outlet (9c)
A pair of connection ports (93) provided at ends of a pair of pipes (91) extending from the outdoor unit (9a) and inserted into the wall hole (90a) and guiding hot water are mounted. A plug (4) provided at the end of a pair of pipes (92) extending from the indoor unit (9b) is detachably connected to these connection ports (93). In this connection state, the connection port (93)
The valve device incorporated in the pipe is opened and the pipe (91) (9
Hot water is circulated between the outdoor unit (9a) and the indoor unit (9b) through 2).

On the other hand, when the plug (94) is removed from the connection port (93) and these connection ports (93) are not used, a cap for covering the connection port (93) as shown in FIG.
(95) is attached. Cap (95) is hot water outlet (9
c) is connected with a string. In this state, since the connection port (93) is covered with the cap (95), dust adheres to the connection port (93) or the connection port (93) is hit by an object hitting the connection port (93). Damage is reduced.

Therefore, when the plug (94) is connected to the connection port (93) again, dust does not enter the pipes (91) and (92) from the connection port (93). Thereby, clogging of the heat exchanger and the like built in the outdoor unit (9a) and the indoor unit (9b) can be suppressed.

[0006]

However, as shown in FIG. 10, when the connection port (93) is used, the above-mentioned cap (9) is used.
The cover (95a) for the connection port (93) of (5) is exposed to the outside. Therefore, dust easily adheres to the covering portion (95a). If dust adheres to the cover (95a), when the cap (95) is attached to the connection port (93), the connection port (9
3) Dust enters inside.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hot water outlet which reliably prevents dust from entering a connection port.

[0008]

Means for solving the problems of the invention according to the first aspect of the invention are as follows: "The end of a pair of pipes which are attached to the indoor side wall surface so as to cover the wall hole and are inserted through the wall hole to guide hot water. A pair of connection ports provided in the portion are mounted, and when the connection ports are not used, a cap for covering each of the connection ports is mounted on the hot water outlet, and the cap removed when the connection ports are used. And a protective member that is detachably attachable and that protects the covering portion of the cap with respect to the connection port in the attached state. ”

When the connection port is used, the cap is removed from the connection port. Then, the cap is attached to the protection member. In this mounting state, the cover of the cap with respect to the connection port is protected by the protection member. Here, as in the invention of claim 2,
"A main body portion to which each of the connection ports is mounted, and each of the connection ports mounted to the main body portion and rotated around the mounting portion to expose each of the mounted connection ports to the outside of the main body portion. Or a lid that is in a non-exposed state, wherein the cap is joined by a linear member having flexibility with respect to the main body, and the protection member is provided on an inner surface of the lid. It may be something.

When the connection port is used, the lid is opened to expose the connection port to the outside of the main body, and the protection member to be exposed to the outside. Then, the cap is removed from the connection port and attached to the protection member. The cap may be connected to the main body by the linear member, or may be installed independently of the main body.

[0011]

As described above, according to the first aspect of the present invention, when the cap removed from the connection port is attached to the protection member when the connection port is used, the protection member causes the cap to be removed. The coating for the connection port is protected. Therefore, adhesion of dust to the coating portion during the use is suppressed. Thus, when the cap is reattached to the connection port, dust does not enter the connection port. That is, it is possible to reliably prevent dust from entering the connection port.

In addition, since the covering portion of the cap is protected during the use, an inconvenience such that the covering portion is damaged by an object hitting the covering portion is suppressed. According to the invention of claim 2, when the connection port is not used, when the cap is attached to the connection port and the lid is closed, the protection member is not exposed to the outside of the hot water outlet. In addition, dust does not adhere to the protection member when not in use. Therefore, when the cap is attached to the protective member when the connection port is used, dust does not adhere to the cover from the protective member.
