【Example】

 An embodiment of the cooking liquid heating device of the present invention will be described below with reference to the drawings.

The embodiment is applied to an industrial fryer that uses a pulse burner, where A is a pulse burner that inhales air and gas by utilizing a high pressure increase due to combustion, In addition, the combustion gas is discharged, and the supply / exhaust of the fan motor and the ignition operation of the spark plug are stopped except when combustion is started, and the combustion cycle of combustion → exhaust → supply is automatically about 80 times per second. The burner is a repeating combustion type, and the combustion chamber 6 and the tail pipe 7 installed in the oil tank 5 heat the oil in the oil tank 5.

V is an oil drain valve provided in an oil drain pipe 8 connected to the bottom of the oil tank 5, and can be opened and closed by reciprocally rotating the operating handle 1 approximately 90 degrees, for example, a ball valve or the like is used. .

Reference numeral B denotes a blocking means for disabling the opening operation of the oil discharge valve V when the pulse burner A is in a state where the ignition try operation can be performed. In the embodiment of FIGS. 1 to 3, the power switch is used. The slide type operation knob 2 and the blocking plate 3 are integrally provided, and the blocking plate 3 moves forward and backward in conjunction with the ON / OFF operation of the operating knob 2, and the operating knob 2 is moved to the right side in the drawing to perform the ON operation. At this time, the blocking plate 3 moves forward to reach one side of the operating handle 1 of the oil drain valve V, prevents the operating handle 1 from rotating in the opening direction (see FIG. 3), and moves the operating knob 2 to the left in the drawing. When it is moved and turned off, the blocking plate 3 is retracted so as to unlock the rotation of the operating handle 1 in the opening direction (see FIG. 2).

In the embodiment shown in FIGS. 4 and 5, a blocking hole 9 is formed in the operating handle 1 of the oil drain valve V, and the tip of the movable iron core 4 of the solenoid M is inserted into and withdrawn from the blocking hole 9. The movable iron core 4 appears and disappears when the solenoid M is connected to the power switch and the solenoid M is turned on and off in conjunction with the power switch being turned on and off. When the power switch is turned on, the solenoid M is turned on and off. When turned on, the movable iron core 4 projects upward in the drawing, and its tip is inserted into the blocking hole 9 of the operating handle 1 to prevent the operating handle 1 from rotating in the opening direction (see FIG. 5), and the power switch is turned off. At this time, the solenoid M is turned off, the movable iron core 4 is lowered downward in the figure, and the tip of the movable iron core 4 is released from the blocking hole 9 of the operating handle 1 to release the rotation blocking of the operating handle 1 in the opening direction. (See Figure 4).

In this embodiment, instead of the power switch, ON / OFF of a solenoid valve provided in a gas supply path and ON / OFF of a solenoid M are interlocked, and when the solenoid valve is ON, the solenoid M is turned ON, The solenoid M may be turned off when the solenoid valve is turned off.

Further, in the above-mentioned embodiment, since the drain oil is at a high temperature, the drain valve V is manually opened / closed by the operating handle 1. However, a solenoid valve that is electrically and automatically opened / closed is applied to the drain valve. Then, when the power switch is ON, it is possible to electrically prevent the opening.

In the above-mentioned configuration, when the power switch is turned on and the pulse burner A is ready for the ignition trial operation, the blocking plate 3 that interlocks with the operation knob 2 of the power switch or the power switch or the gas solenoid valve is turned on or off. The movable iron core 4 of the solenoid M, which is turned on and off in conjunction with the above, prevents the operation handle 1 of the oil drain valve V from rotating in the opening direction, so that oil cannot be drained.

In FIG. 1, reference numeral 10 denotes an oil temperature sensor, which detects the oil temperature in the oil tank 5 and stops the combustion of the pulse burner A when the oil temperature becomes higher than a set temperature, and lowers the temperature below the set temperature. When it gets worse, it starts burning. Reference numeral 11 is an air chamber, 12 is an air supply fan, 13 is an exhaust muffler, and 14 is a gas supply pipe.

Although the present invention is applied to the industrial frying machine in the above-described embodiments, it goes without saying that the invention can also be applied to a cooking liquid heating device such as a boiled noodle machine.
