Abstract

PURPOSE:To prevent the damage to a gas pipe and the defective gas supply by connecting a flexible body between the rear part of a placing base which can be drawn out and a main body frame, and allowing the gas pipe to go along with this flexible body in a longitudinal direction, and also, holding it. CONSTITUTION:Between the rear part of a placing base 53 and a main body frame 82, a flexible body 72 which extends and contracts in connection with the forward/backward motion of the placing base 53 is connected, and a gas pipe 76 connected to a rice cooker main body device 42 is allowed to go along with the flexible body 72 in the longitudinal direction, and simultaneously held. When the rice cooker main body device 42 is placed and the placing base 53 is pushed in from a drawn-out state, the flexible body 72 is bent between the placing base 53 and the main body frame 82, and the gas pipe 76 is also bent along it, but it is guided by the flexible body 72 and bent large and suitably, held between the placing base 53 and the main body frame 82 and a gas flow is not obstructed. Also, a gas ignition electric cord 77 is not held therebetween in the same manner as the gas pipe 76, and since no bend like an acute angle is present thereon, damage is also small.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic rice cooking device for commercial use that automatically performs everything from measuring to cooking rice.

0002

[Prior art] This type of prior art includes Japanese Unexamined Patent Publication No. 59
- There is a device disclosed in Publication No. 181113, which includes a rice storage section for storing rice, a measuring section for weighing and discharging the rice in the rice storage section, a rice washing section for washing the rice discharged from the measuring section, and a rice washing section for washing the rice discharged from the measuring section. The rice cooker includes a rice cooking section that cooks the rice discharged from the rice washing section, and a rice cooker main unit is housed in the rice cooking section.

0003

[Problems to be Solved by the Invention] In the prior art, the rice cooker main unit is housed within the main body frame, making it difficult to take out the rice cooker main unit. This problem can be easily solved by making the mounting table that is in place removable. However, if the main unit of the rice cooker is a gas combustion type, the gas pipe and electric cord for gas ignition must be connected, and if the mounting stand is a pull-out type, these will connect to the main body frame when the mounting stand is pushed in. It may get caught between the two, causing damage or gas supply failure.

[0004] A first object of the present invention is to connect a bending body between the rear part of a drawable mounting table and the main body frame, and to hold a gas pipe along the longitudinal direction of the bending body. To provide an automatic rice cooking device that prevents damage to gas pipes and gas supply failure. A second object of the present invention is to strengthen the gas pipe by fitting a spiral body therein, and also to prevent damage to the electric cord by holding the gas ignition electric cord together with the gas pipe in a bendable body. An object of the present invention is to provide an automatic rice cooking device.

[0005]

[Means for Solving the Problems] A first specific means for solving the problems in the present invention is to provide a rice storage section 3 for storing rice;
It includes a measuring section 4 that measures and discharges the rice in the rice storage section 3, a rice washing section 5 that washes the rice discharged from the measuring section 4, and a rice cooking section 7 that cooks the rice discharged from the rice washing section 5. The rice cooker main unit 42 of the rice cooking section 7 is an automatic rice cooker placed on a mounting table 53 that is removably provided on a main body frame 82.
A bending body 72 that bends and stretches as the mounting table 53 moves back and forth is connected between the two, and a gas pipe 76 connected to the rice cooker main unit 42 is held along the bending body 72 in the longitudinal direction. That's true.

In addition to the first specific means, a second specific means for solving the problems of the present invention is to fit a spiral body 75 into the gas pipe 76 and to connect the gas pipe 76 to the rice cooker main unit 42. The ignition electric cord 77 is held along the bending body 72 along with the gas pipe 76 in the longitudinal direction.

[0007]

[Operation] When the placing table 53 on which the rice cooker main unit 42 is placed is pushed in from the pulled out state, the bending body 72 is bent between the placing table 53 and the main body frame 82, and the gas pipe 76 is also bent along it. However, it is guided by the bending body 72 and bent largely and appropriately, so that it will not be pinched between the mounting table 53 and the main body frame 82 and the gas flow will not be blocked. Furthermore, like the gas pipe 76, the gas ignition electric cord 77 is not pinched and is not bent at an acute angle, so it is less likely to be damaged. Helix 75 protects gas tube 76 and prevents sharp bends.
