DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cooking liquid heating apparatus according to the present invention will be described below with reference to the drawings.

The embodiment is applied to an industrial fryer using a pulse burner. A is a pulse burner, which sucks air and gas by utilizing a high pressure rise caused by combustion. At the same time, the combustion gas is discharged, and the combustion cycle of the combustion → exhaust → supply air is repeated about 80 times per second automatically by stopping the supply / exhaust by the fan motor and the ignition operation by the ignition plug except at the start of combustion. This is a burner of a system in which oil in the oil tank 5 is heated by a combustion chamber 6 and a tail pipe 7 installed in the oil tank 5.

Reference numeral V denotes an oil drain valve provided on an oil drain pipe 8 connected to the bottom of the oil tank 5. The oil drain valve can be opened and closed by reciprocating the operation handle 1 by approximately 90 degrees, for example, using a ball valve or the like. .

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 capable of performing the ignition try operation. The embodiment shown in FIGS. The sliding operation knob 2 and the blocking plate 3 are provided integrally, and the blocking plate 3 moves forward and backward in conjunction with the ON / OFF operation of the operation knob 2, and moves the operation knob 2 rightward in the figure to turn ON.
When operated, the blocking plate 3 moves forward and the operating handle 1 of the drain valve V
, The operation handle 1 is prevented from turning in the opening direction (see FIG. 3), and the operation knob 2 is moved to the left in the figure to turn off the OF.
When the F operation is performed, the blocking plate 3 is retracted to release the rotation of the operation handle 1 in the opening direction (see FIG. 2).

4 and 5 show an oil discharge valve V
The operating handle 1 is provided with a blocking hole 9, and the tip of the movable iron core 4 of the solenoid M is inserted into and removed from the blocking hole 9. The solenoid M is connected to a power switch to turn on and off the power switch. Solenoid M turns ON and OF in conjunction
When the power is turned on, the solenoid M is turned on, and the movable core 4 rises upward in the drawing and protrudes, and its tip is inserted into the blocking hole 9 of the operation handle 1. When the power switch is turned off, the solenoid M is turned off, the movable iron core 4 descends and sinks, and the tip of the operation handle 1 is turned off. The control handle 1 escapes from the blocking hole 9 to prevent the operation handle 1 from rotating in the opening direction (see FIG. 4).

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

In the above-described embodiment, the oil drain valve V is of the type that is manually opened and closed by the operation handle 1 because the oil drain is at a high temperature. However, a solenoid valve that automatically opens and closes electrically is applied to the oil drain valve. Thus, when the power switch is ON, it can also be a blocking means having a structure for electrically blocking the opening.

In the above configuration, when the power switch is turned on and the pulse burner A is ready to perform the ignition try operation, the blocking plate 3 or the power switch or the gas solenoid valve which moves forward and backward in conjunction with the operation knob 2 of the power switch is operated. ON, OF
Oil can not be drained because the movable iron core 4 of the solenoid M which turns on and off in conjunction with F prevents the operation handle 1 of the oil drain valve V from rotating in the opening direction.

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 the set temperature, and lowers the oil temperature below the set temperature. If it does, it will start burning. 11 is an air chamber, 12 is an air supply fan, 13 is an exhaust muffler,
14 is a gas supply pipe.

In the above embodiment, the present invention is applied to an industrial frying machine, but it is needless to say that the present invention can also be applied to a boiled noodle machine and other cooking liquid heating devices.

[0018]

According to the cooking liquid heating apparatus of the present invention, for example, when the power supply switch is turned on and the cooking liquid heating means is in an ignitable state, the operation of opening the cooking liquid discharge valve cannot be performed. As described above, there is no danger of empty firing due to the descent of the oil level due to oil drainage.

In order to prevent the operation handle from turning in the opening direction, in addition to mechanical blocking means performed by a blocking plate interlocked with the operation knob of the power switch, the power switch or gas valve O
If any of the electrical blocking means performed by the movable iron core of the solenoid that turns ON and OFF in conjunction with N and OFF is applied,
Combined with the simple structure, it is easy to assemble to an existing device, and the cost is low.
