Illustration 1 of Japanese Industrial Standard S 2120-1992

  In the conventional gas outlet described above, the secondary side connection portion of the branch pipe portion is provided downward. However, the gas equipment connected to the branch pipe portion via the secondary gas pipe is installed above the gas outlet. Therefore, when connecting the branch pipe part and the gas appliance in the kitchen, the vicinity of the branch pipe part of the secondary side gas pipe must be bent in a “U” shape. For this reason, there existed a problem that the length of the secondary side gas pipe became long and the expense increased correspondingly. In addition, when the secondary gas pipe is curved in a “U” shape, there is a problem that the flow resistance in the secondary gas pipe increases.

In order to solve the above-mentioned problem, the present invention has a main body, a plug portion provided in the main body, and a downstream end connected to the plug, and a primary gas pipe is connected to the upstream end. An inlet pipe portion provided with a primary side connection portion to be connected, and a branch pipe provided with a secondary side connection portion branched from the introduction pipe portion and connected to a secondary gas pipe at a downstream end portion The secondary outlet is provided in any direction between the horizontal direction and vertically upward.
In this case, the primary side connecting portion is provided vertically downward, the secondary side connecting portion is provided vertically upward, and the primary side connecting portion and the secondary side connecting portion are vertically arranged. It is desirable that they are arranged in a straight line.
It is desirable that the primary side connection portion and the secondary side connection portion are provided in a horizontal direction, and the primary side connection portion and the secondary side connection portion are arranged side by side.
It is desirable that the primary side connection portion is provided vertically downward, and the secondary side connection portion is provided horizontally.
It is desirable that the secondary side connection part of the branch pipe part is disposed above the primary side connection part of the introduction pipe part.

  According to the present invention having the above-described characteristic configuration, since the secondary side connection portion of the branch pipe portion is provided in any direction between the horizontal direction and the vertically upward direction, the branch pipe portion is connected to the branch pipe portion. The secondary gas pipe does not need to be bent in a “U” shape, and it is sufficient if it is bent at a right angle at the maximum. Therefore, the length of the secondary side gas pipe can be shortened. Moreover, the flow resistance in the secondary side gas pipe can be reduced.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 3 show a first embodiment of the present invention. In this embodiment, a gas outlet 1 according to the present invention is provided on a partition wall W of a face-to-face kitchen, and the height between the kitchen K and the living room L is 1 m as shown in FIG. A partition wall W having a height of about 1 m50 cm is provided on the floor F. The partition wall W includes a first wall plate W1 facing the living room L and a second wall plate W2 facing the kitchen K. A space is formed between the first and second wall plates W1 and W2, and an upper end portion of the space is closed by a table T provided at an upper end portion of the partition wall W.

  At the end of the base 6 on the living room L side, a plug 6a is provided. The plug portion 6a extends in the horizontal direction, and is disposed with its tip end face opposed to the through hole Wa. Inside the base 6, vertical gas holes 6b and horizontal gas holes 6c are formed. The vertical gas hole 6 b extends upward from the lower end surface of the base 6. The horizontal gas hole 6c extends horizontally with its axis line coinciding with the axis line of the plug portion 6a. One end of the horizontal gas hole 6c is open to the end face of the base 6 on the kitchen K side, but the opening is closed by a lid 6d. The other end of the horizontal gas hole 6c is open to the tip surface of the plug 6a. The horizontal gas hole 6c intersects with the upper end of the vertical gas hole 6b at the intermediate part thereof. Therefore, the vertical gas hole 6b and the horizontal gas hole 6c communicate with each other. Gas is supplied to the vertical gas hole 6b via the pipe part 7.

  Inside the vertical gas hole 6b, there is provided an overflow prevention valve 8 that closes the vertical gas hole 6b when the flow rate of the gas flowing through the inside exceeds a predetermined amount. On the other hand, a main valve 9 and a sub valve 10 are provided inside the horizontal gas hole 6c. The main valve 9 and the sub-valve 10 open the horizontal gas hole 6c when a socket (not shown) defined in Japanese Industrial Standard JIS S 2135 is connected to the plug portion 6a. As a result, the gas supplied to the vertical gas holes 6b is supplied to the gas equipment via the horizontal gas holes 6c, the socket, and the gas pipe (secondary gas pipe) connected to the socket. The main valve 9 and the sub valve 10 close the horizontal gas hole 6c when the socket is removed from the plug portion 6a. Since the overflow prevention valve 8, the main valve 9 and the sub valve 10 are well known, detailed description of their structure is omitted.

  The pipe part 7 has an introduction pipe part 11 and a branch pipe part 12 that are integrally formed with each other. The introduction pipe part 11 and the branch pipe part 12 are arranged on one vertical plane including the axis of the plug part 6a. Of course, the introduction pipe part 11 and the branch pipe part 12 may be arranged on different vertical planes. The introduction pipe portion 11 is formed in a substantially “<” shape, and an upper end portion thereof is attached to a lower end portion of the base portion 6. The inside of the introduction pipe portion 11 communicates with the vertical gas hole 6b. The lower end portion of the introduction pipe portion 11 is inclined so as to approach the kitchen K as it goes downward. The branch pipe portion 12 is integrally provided at the upper end portion of the inclined portion of the introduction pipe portion 11 and extends in a direction substantially orthogonal to the inclined portion. That is, the branch pipe portion 12 is inclined so as to approach the kitchen K as it goes upward. As a result, the distal end portion of the branch pipe portion 12 is positioned above the lower end portion of the introduction pipe portion 11. The inside of the branch pipe part 12 is communicated with the inside of the introduction pipe part 11.

  A primary side connection portion 13 is provided at the lower end portion of the introduction pipe portion 11. This primary side connection part 13 is for connecting the primary side gas pipe G1 to the introduction pipe part 11, and the structure is determined according to the kind of primary side gas pipe G1. For example, in this embodiment, since a flexible gas pipe is used as the primary side gas pipe G1, a connection structure for a flexible gas pipe is adopted as the primary side connecting portion 13. In particular, in this embodiment, a one-touch type connection structure that can be connected by simply inserting the flexible gas pipe into the lower end portion of the introduction pipe section 11 is employed. In the case where a rigid gas pipe is used as the primary side gas pipe G1, for example, a tapered female screw is employed as the primary side connection portion 13. In addition, as shown in FIG. 1, the primary side gas pipe G1 is drawn between the system kitchen S and the second wall plate W2 from the through hole Wb formed in the second wall plate W2, and the space between them is downward. Extending through the floor F and connected to a main plug (not shown). Therefore, gas is supplied to the introduction pipe part 11 from the primary side gas pipe G1.

  A secondary side connection portion 14 is provided at the distal end portion of the branch pipe portion 12 positioned above the primary side connection portion 13 of the introduction pipe portion 11. This secondary side connection part 14 is for connecting the secondary side gas pipe G2 to the branch pipe part 12, and its structure is determined corresponding to the type of the secondary side gas pipe G2. In this embodiment, since the flexible gas pipe G2 is adopted as the secondary side gas pipe G2, a one-touch connection structure for the flexible gas pipe is adopted. Of course, when a rigid gas pipe is used as the secondary side gas pipe G2, a taper female thread is adopted as the secondary side connection portion. Note that the secondary gas pipe G2 is drawn out between the system kitchen S and the second wall plate W2 from the through hole Wb, and extends upward between them, and is formed in the housing S1 of the system kitchen S. The gas is introduced into the system kitchen S through the hole S2 and connected to a gas stopper GV for a gas table (gas appliance) GT.

  In the gas outlet 1 having the above-described configuration, the branch pipe portion 12 is provided obliquely upward. As is apparent from FIG. 1, the gas plug GV of the gas table GT disposed above the gas outlet 1 is provided. When connecting the secondary side gas pipe G2, it is not necessary to bend the vicinity of the branch pipe portion 12 of the secondary side gas pipe G2 in a “U” shape, and it is only necessary to bend it slightly by about 45 °. Therefore, the length of the secondary side gas pipe G2 can be shortened, and the flow resistance in the secondary side gas pipe G2 can be reduced.

  Moreover, in the gas outlet 1 of this embodiment, since the secondary side connection part 14 is arrange | positioned upwards with respect to the primary side connection part 13, compared with the conventional thing which arrange | positioned both at the same height. Thus, the length of the secondary gas pipe G2 can be shortened by the difference in arrangement position. Moreover, the primary side and secondary side gas pipes G1, G2 can be easily connected to the primary side and secondary side connection portions 13, 14, respectively. That is, assuming that the primary side and secondary side connection portions 13 and 14 are arranged at the same height, after connecting one of the primary side and secondary side gas pipes G1 and G2, the other is connected. Sometimes, one of the previously connected gas pipes obstructs the connection. In this regard, according to the gas outlet 1 of this embodiment in which the secondary side connection portion 14 is arranged at a position higher than the primary side connection portion 13, any of the primary side and secondary side gas pipes G1, G2 is connected first. Even in this case, when the other is connected, the previously connected one does not get in the way. Therefore, the primary side and secondary side gas pipes G1, G2 can be easily connected.
