There is one disclosed in Japanese Patent Publication No. 160617 and one disclosed in Japanese Unexamined Patent Application Publication No. 161913/1983. This one has an upper frame that removably accommodates a rice cooker, and a rice cooking function unit that is connected to the lower part of the upper frame. It consists of a lower frame part housed therein, and these parts can be pulled out as a unit from the cabinet.

Therefore, the rice cooker, which was conventionally left on the top of the sink, etc., can be stored inside the sink (cabinet) when not in use, making it easier to organize the kitchen, and the top of the sink, etc. It can be organized beautifully.

However, when this type of rice cooker is used as a gas rice cooker, it is troublesome to install gas piping to the rice cooker.

This is because piping inside the cabinet must be carried out with the cabinet installed. Moreover, the piping from this piping to the rice cooker needs to be expandable and contractible or bendable. That is, this is because the rice cooker must be in the gas connection state both when it is in the pulled-out state and when it is in the pushed-in state.

As a piping structure for realizing this latter requirement, the piping configuration disclosed in Japanese Utility Model Publication No. 62-34488 can be adopted. In the case of this piping configuration, the rice cooker can be taken in and out without applying excessive external force to the flexible tube that connects the fixed piping end and the hose end of the rice cooker.

However, in the conventional system, sufficient consideration is not given to the piping inside the cabinet and the connection between the piping and the flexible tube.

The present invention has been made based on such requirements, and is based on the following: ``A rice cooking chamber 10 for accommodating a rice cooker and a drawer stand equipped with the rice cooker is formed in a cabinet, and the rice cooking chamber 10 is disposed in a fixed part of the cabinet. The purpose of this invention is to simplify the connection work between the connecting pipe 41 and a piping terminal disposed in the cabinet installation part in the pull-out rice cooker in which the connecting pipe 41 connected to the rice cooker is connected to the rice cooker. do.

[Technical Means] The technical means of the present invention taken to solve the above problems is as follows: A drawer stand equipped with a rice cooker is removably provided in the cabinet, and a connecting pipe 41 is provided below the moving area of the drawer stand. A second piping chamber 40 is formed to accommodate the piping from the rice cooker to the rice cooker, and a first piping chamber 45 is formed below the bottom wall of the rice cooking chamber 10 to accommodate the piping to the connecting pipe 41. A connecting pipe 41 is provided in the ceiling of the piping room so as to penetrate into the second piping room 40, and the inlet side of the connecting pipe 41 and the end of the pipe introduced into the first piping room 45 are connected by screws. In addition, a relatively large working opening 47 is provided in the ceiling of the first piping room 45 over a certain range from the upper part of the screw connection part to the rear part thereof.
is provided, the working opening 47 is removably closed by a cover plate 48, and the working opening 47 is set to a size that allows a piping tool such as a spanner to be swung up and down, The swinging range of the tool corresponding to the threaded connection portion is included in the working opening 47.

[Operation] The above technical means of the present invention operates as follows.

Prior to installation of the cabinet, the piping to the lever cabinet is placed in place. The cabinet is installed so that this piping is located in the first piping chamber 45, and with the cover plate 48 removed, a tool is inserted through the working opening 47 to connect the end of the piping and the connecting pipe 41 with screws. do. At this time, the drawer stand has been removed from the rice cooking chamber 10.

Next, after the connection is completed, the drawer is inserted into the rice cooking chamber 10 and the rice cooker provided therein is connected to the connecting pipe 41, so that the entire piping is connected.

Further, when repairing the piping after installing the equipment, the drawer stand is removed contrary to the above, and the piping in the first piping chamber 45 is inspected and repaired with the cover plate 48 removed.

[Effects] Since the present invention has the above configuration, it has the following unique effects.

With the pull-out stand equipped with the rice cooker removed, the piping in the first piping chamber 45 can be connected or disconnected through the work opening 47, making it easy to connect or disconnect the piping in the cabinet to pre-installed piping.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5.

As a whole, the embodiment shown in the drawings is of the first type.
With the configuration shown in the figure, a normal rice cooker that is placed on a table or the like can be directly attached to a drawer stand. The underframe 31 and

The upper frame part 12 is removably mounted on the lower frame part 11 which is attached and fixed as described above. This upper frame part 12 is equipped with a heat retention function, and its power cord is wound around a cord reel 15 as shown in FIG. It is removably connected to the

As mentioned above, a front plate 37 is connected to the front edge of the frame 31 for mounting and supporting the rice cooker, and this front plate 37 is set to a size that just closes the open end of the rice cooking chamber 10. , this front plate 37 and the underframe 31 are integrated.

Next, a sufficient space is formed below the bottom plate of the rice cooking chamber 10, and this space serves as a first piping chamber 45.

A gas pipe from the outside is introduced and connected into this first piping chamber 45 , and a connecting pipe 41 having an inlet side connection part is connected to the first piping chamber 45 .
It penetrates the bottom plate of the rice cooking chamber 10, which is the top wall of the rice cooker 5, and its exit side is surrounded by the underframe 31.
It protrudes into the piping chamber 40. This second piping chamber 4
Inside the cooking chamber 1, gas piping and a power supply connection device for the entire device are installed, and an electromagnetic connector 21 provided at the rear end of the top surface of the frame 31 connects the rice cooker 1.
It faces the electromagnetic connected device 22 attached to the rear wall of the vehicle.

The combination of the electromagnetic connecting device 21 and the electromagnetic connected device 22 is a normal magnetic power source connecting device, and in this embodiment, the electromagnetic connected device 2

Then, when the mounting position of the electromagnetic connecting device 21 is set to a predetermined value and the underframe 31 is pushed into the final position, the connecting end of this and that of the electromagnetic connected device 22 are brought into contact with each other and electrically connected. Become. Further, this electrical connection state is maintained by the attraction force of the magnets of the electromagnetic connecting tool 21 and the electromagnetic connected tool 22.

Therefore, rice cooking and warming operations are possible with the drawer pushed in, and the rice cooker is automatically set to a stopped state with the drawer pulled out.

Next, in order to supply gas to the gas rice cooker, a combination of flexible piping and fixed piping was adopted, and the rice cooking chamber 10
A first piping chamber 45 is formed below the bottom wall, and a second piping chamber 40 surrounded by the underframe 31 is formed above the bottom wall. A connecting pipe 41 is provided in the ceiling of the first piping chamber so as to penetrate into the second piping chamber 40, and the outlet side of the connecting pipe 41 and the hose end 14 provided on the lower frame portion 11 are compared with each other. They are connected by an elastic rubber tube 42 with high rigidity.

The outlet side of the connecting pipe 41 is located within the second piping chamber 40, and the other hose end 14 is located within the box body 33. As shown in FIG. 4, these hose ends 14 and the outlet of the connecting pipe 41 are located on the opposite side to the center line of the movement locus of the underframe 31, and the elastic rubber pipe 42 is connected to the hose end 14. Both directions are set to face backwards. moreover,
The elastic rubber tube 4 is set to be sufficiently longer than the straight line distance between these hose ends 14 and the elastic rubber tube 42.
2 is connected between the outlet of the connecting pipe 41 and the hose end 14. Therefore, when the elastic rubber tube 42 having the above-mentioned predetermined rigidity is connected between the connecting tube 41 and the hose end 14, the elastic rubber tube 42 has an arc shape as shown in FIGS. 2 and 4. In the bent state, it rises obliquely from the outlet of the connecting pipe 41 toward the hose end 14.

In this embodiment, a rectangular notch 35 as shown in the figure is formed at the rear end of the top surface of the second piping chamber 40 configured in the underframe 31. The section rises obliquely from the second piping chamber 40 toward the hose end 14 through a space sufficiently distant from the rear wall of the rice cooking chamber 10 and the periphery of the notch 35 . Incidentally, here, the connection pipe 41
is located near the front edge of the rice cooking chamber 10, as shown in FIG.

On the other hand, inside the first piping chamber 45, as shown in FIG. 43 and the bag nut and the entrance portion 43
It is connected by a piping connector H that is made of a chiseled male threaded portion. This piping connector H connects an end piping 46 that has been piped indoors in advance and the connecting pipe 4 that is provided in a cabinet as a device.
This is to enable connection with 1.

In this embodiment, the end pipe 46 is connected to the first pipe chamber 4
It is arranged in the left and right direction at the bottom of 5.
The end of this end pipe 46 is located at a position shifted rearward from the lower end of the connecting pipe 41.

Furthermore, a rectangular working opening 47 is provided in the ceiling of the first piping chamber 45 over a certain range from the rear upper part of the piping connector H.
removably closed by.

The size of this working opening 47 is set to a size that allows piping tools such as spanners to be swung up and down, and the connection between the piping fitting H and the end of the end piping 46 is made using a screw connection method. We are hiring. Therefore, with the cover plate 48 removed, the screw joint between the pipe connector H and the end pipe 46 can be connected or removed by inserting a tool through the working opening 47 as described above.

Note that this connection work or removal work is performed on the underframe 31.
This will be done separately outside the cabinet.

In the case of the above piping structure, when the equipment is installed,
Gas is supplied from the end pipe 46 to the rice cooker via the pipe connector H, the connecting pipe 41 and the elastic rubber pipe 42. When the frame 31 is pushed into the final position, the rear end of the bent portion of the elastic rubber tube 42 is located near the rear wall of the cooking chamber 10, as shown by the solid line in FIGS. 2 and 4. When the underframe 31 is pulled out, it is bent into a flat elliptical arc shape, as shown by the imaginary line in FIG.

Thereafter, when the underframe 31 is pushed from the pulled-out position to the pushed-in position, the elastic rubber tube 42 as a whole remains bent in the same direction, and the curvature of the bent portion and the position of the bent portion in the elastic rubber tube 42 are changed. It deforms in a manner that changes and returns to its initial state.

In this way, the drawer position of the underframe 31 and the underframe 3
1, the elastic rubber tube 4
2 are bent in the same direction to connect the hose end 14 and the connecting pipe 41. Therefore, the elastic rubber tube 42 does not have excessive bending, and is always suspended in the air between the hose end 14 and the connecting tube 4.
1 will be connected.

In this bending deformation of the elastic rubber tube 42, since the outlet portion of the connecting tube 41 is configured to be swingable, the deformation of the elastic rubber tube 42 is also smooth. However, if the elastic rubber tube 42 has a sufficient degree of bending elasticity, the outlet portion of the connecting tube 41 does not need to be swingable.

Further, in this embodiment, the front opening of the rice cooking chamber 10 is closed by the front plate 37 when the frame 31 is pushed in, but as shown in FIG. 2, the upper end of the front plate 37 An exhaust duct 5 formed inside the rice cooking chamber 10 with an exhaust port 51 formed on one side.
The combustion exhaust gas and generated steam sucked by the fan 50 are discharged from the fan 51 via the fan 50 .
