Therefore, in particular, as shown in FIG. 4, the gas pipes are connected in a so-called drop-in installation form in which the gas stove 62 is dropped into the opening 61 provided in the counter top 60 of the system kitchen unit. In this case, since the gas stove 62 was set in the opening 61 and the relay pipe and the connecting pipe were connected, the work space in the front-rear direction (arrow A in the figure) was limited, and workability was poor.
[0006]
Specifically, the installation operator of the gas stove 62 holds the connection pipe 55 (see FIG. 3) and puts the hand inside the gas stove 62, and connects the connection pipe 55 to the connection port 57 of the relay pipe 54 and the gas stove. The connection to the connection port 58 of the filter pipe 56 is performed, but the connection port 57 of the relay pipe 55 and the connection port 58 of the gas stove pipe 56 are opened laterally inside the gas stove 62. It is difficult for the installation worker to visually recognize, and these openings may be hidden by the operator's hand.
[0007]
Further, since there is a structure such as a gas conduit of a stove burner in the gas stove 62, the connecting pipe 55 gripped by the operator is slid in the lateral direction to connect the connecting port 57 of the relay pipe 54 with the connecting port 57. It was difficult to connect to the connection port 58 of the gas stove pipe 56.
[0008]

In addition, when the inlet member is fixed to the bottom plate of the gas stove, the gas oven is installed even if the upward opening of the gas stove connection port is located at a low height near the bottom plate. In this case, since the connection work between the upward opening of the gas stove connection port and the relay pipe is performed from above the upward opening, the workability of pipe connection does not deteriorate.
[0020]
DETAILED DESCRIPTION OF THE INVENTION
An example of an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an explanatory diagram of an installed state of a gas stove, and FIG. 2 is a diagram showing a mode in which the gas stove and a relay pipe are connected via a connecting pipe.
[0021]
Referring to FIG. 1 (a), gas stove 6 (see FIG. 1 (b)) in the present embodiment is a drop that is dropped into opening 2 provided in countertop 1 of the system kitchen unit. In the in-type installation form, the countertop 1 is suspended and installed above the gas oven 3 installed in the lower part of the system kitchen unit.
[0022]
A connecting port 5 of the relay pipe 4 for leading the fuel gas supplied from a gas main pipe (not shown) to the installation position is opened at the installation position of the gas stove 6. Here, since the relay pipe 4 is fixed at a predetermined position on the back surface of the gas oven 3, the connection port 5 of the relay pipe 4 is positioned at a fixed position with respect to the installation position of the gas oven 3.
[0023]
Next, as shown in FIG. 1 (b), the installation operator of the gas stove 6 drops the gas stove 6 from the opening 2 and forms flanges 9 formed on the upper four sides of the gas stove 6. At this time, the gas stove 6 is positioned to some extent by the opening 2 and is relayed via a notch 8 formed from the bottom plate of the gas stove 6 to the side plate. The connection port 5 of the tube 4 is exposed near the side plate inside the gas stove 6. Then, the operator aligns the positioning holes provided in advance on the bottom plate of the gas stove 6 with the fixing holes (not shown) provided in advance on the top plate of the gas oven 3, and the bottom plate of the gas stove 6 and the gas oven 3. The top plate is screwed with a connecting screw (not shown).
[0024]
Thereby, the gas stove 6 and the gas oven 3 are positioned while maintaining a predetermined positional relationship. In addition, after the piping work of the gas stove 6 is completed, the top plate exposing only the burner portion and the exhaust port is placed on the counter top 1 so as to cover the upper side of the gas stove 6.
[0025]
On the other hand, the member in which the connection port 7 of the gas stove 6 is formed is screwed into a mounting hole (not shown) provided in advance in the bottom plate of the gas stove 6 by a fixing screw (not shown). The connection port 7 of the stove 6 is positioned at a predetermined position on the bottom plate.
[0026]
Therefore, when the bottom plate of the gas stove 6 and the top plate of the gas oven 3 are connected by the connecting screw while maintaining a predetermined positional relationship, the connection port 5 of the relay pipe 4 and the connection port 7 of the gas stove 6 are also connected. It will be positioned in a predetermined positional relationship. The connection port 5 of the relay pipe 4 and the connection port 7 of the gas stove 6 are both open upward in the same direction toward the opening 2.
[0027]
2 (a) and 2 (b) are diagrams showing the installation state of the connection port 7 and the relay pipe 4 of the gas stove 6 of FIG. 1 (b) as viewed from the right side. And the connection port 5 of the relay pipe 4 opens in the same upward direction. Therefore, the installation operator of the gas stove 6 can connect the gas stove 6 with the gap between the connection ports at both ends so that it can be inserted into the connection port 7 of the gas stove 6 and the connection port 5 of the relay pipe 4 in advance. A connection pipe 18 formed in accordance with the distance between the port 7 and the connection port 5 of the relay pipe 4 can be inserted into the connection port 7 of the gas stove 6 and the connection port 5 of the relay pipe 4 from above.
[0028]
In this case, the operator visually confirms the positions of the connection port 7 of the gas stove 6 and the connection port 5 of the relay pipe 4 from above the gas stove 6 with no restrictions on the work space, and connects the connection pipe 18 to the gas. By simultaneously inserting the connecting port 7 of the stove 6 and the connecting port 5 of the relay pipe 4 and applying a downward force, the connecting pipe 18 is connected to the connecting port 7 of the gas stove 6 and the connecting port 5 of the relay pipe 4. Can be connected easily.
[0029]
Further, since the position of the connection port 5 of the relay pipe 4 is higher than that of the connection port 7 of the gas stove 6, the operator can easily see the connection port 5 of the relay pipe 4 and is close to the side plate. The connection between the relay pipe 4 and the connection pipe 18 in the vicinity of the connection port 5 of the narrow relay pipe 4 can be easily performed.
[0030]
Here, retaining plates 19a and 19b (corresponding to the retaining members of the present invention) are mounted in the vicinity of both connection ports of the connecting pipe 18 so as to be rotatable and movable in the vertical direction, respectively. , 19b are kept from coming off by the cording portions 16a, 16b at both ends of the connecting pipe 18, respectively. The retaining plate 19a has a through hole 20a, and the retaining plate 19b has a through hole 20b.
[0031]
Then, O-rings 17a and 17b are attached to the cording portion 16a, and O-rings 17c and 17d are also attached to the cording portion 16b. For this reason, when the connecting pipe 18 is inserted into the connecting port 7 of the gas stove 6 and the connecting port 5 of the relay pipe 4, the connection points of the connecting pipe 18 and the gas stove 6 and the connecting pipe 18 are connected by these O-rings 17a to 17d. And the airtightness of the connection location of the relay pipe 4 is maintained.
[0032]
Further, the flange portion 10 in which the connection port 5 of the relay pipe 4 is formed is provided with a screw hole 11, and the connection port 7 of the gas stove 6 is formed and the flange of the inlet member 25 fixed to the bottom plate 14. The part 12 is also provided with a screw hole 13.
[0033]
Then, as shown in FIG. 2B, the operator inserts the connection pipe 18 into the connection port 5 of the relay pipe 4 and the connection port 7 of the gas stove 6, and then attaches the retaining plate 19 a to the relay pipe 4. The bolt 30a is slid to the collar portion 10 and screwed into the screw hole 11 of the collar portion 10 through the through hole 20a of the retaining plate 19a. As a result, the connection pipe 18 and the connection port 5 of the relay pipe 4 are screwed together, and the connection pipe 18 can be prevented from coming off from the connection port 5 of the relay pipe 4.
[0034]
Similarly, the operator slides the retaining plate 19b to the collar portion 12 of the inlet member 25, and screws the bolt 30b into the screw hole 13 of the collar portion 12 through the through hole 20b of the retaining plate 19b. Thereby, the connection pipe 18 and the connection port 7 of the gas stove 6 are screwed together, and the connection pipe 18 is prevented from coming out of the connection port 7 of the gas stove 6.
[0035]
In addition, the inlet member 25 is provided with connection ports on the side surface and the bottom surface, and a gas pipe 15 communicating with a burner (not shown) of the gas stove 6 is connected to the connection port 26 on the side surface. On the other hand, the connection port 21 provided on the bottom surface is closed with a seal plug 22. The connection port 21 (corresponding to the opening on the bottom plate side of the present invention) provided on the bottom surface uses the gas stove 6 alone without using the gas oven 3, and the gas main pipe serves as the gas stove. This is for use when connecting the main pipe and the gas stove 6 when the base pipe 6 is extended to the vicinity of the bottom surface.
[0036]
Thus, by providing the connection port 7 on the upper surface of the inlet member 25 and also providing the connection port 21 on the lower surface, the fuel gas is supplied to the gas stove 6 from above and below the gas stove 6. Both can be handled with a single member.
