Description

[Detailed description of the invention] The present invention fixes the base of an electric heater submerged in the oil tank to the upper edge of the opening of the oil tank, and detects the oil temperature in the oil tank to activate the electric heater. A support structure for a capillary tube in a portion where the capillary tube that communicates the main body of the thermostat and the oil temperature sensing section penetrates the wall of the control box, in a control box that houses the main body of a gas-filled thermostat that controls energization. To provide a structure suitable for attaching a thermostat to a control box, easily removing the thermostat from the control box, and suitable as a special frying machine.

Next, embodiments of the present invention will be described in detail based on the drawings.

Reference numeral 1 denotes a special frying machine, in which a control box 4 whose both ends are supported by struts 3 at the upper edge of the upper opening of an oil tank 2 is supported by a handle 5 so as to be rotatable upward.

6 is an oil tank 2 whose base is fixed to the control box 4.
The main body of the gas-filled thermostat consists of an electric heater submerged in oil, and a large-diameter temperature-sensing part 9 that senses the amount of oil in the oil tank 2, which is communicated with a small-diameter capillary tube 8. Detects the increased oil temperature and expands the bellows inside the main body 7 through the capillary tube 8 by the action of the gas sealed therein, thereby operating the switch and controlling the energization to the electric heater 6. do.

10 is a knob for adjusting the operating point of the thermostat.

A hole 11 with a slightly larger diameter than the temperature sensing part 9 is bored in the front wall of the control box 4 so that the temperature sensing part 9 can pass through.
An insertion columnar part 12A having a screw thread formed on the outer surface and a diameter slightly smaller than that of the hole 11 is inserted into this hole 11, and a support body 12 having a collar 12B located on the front side of the front wall of the control box 4 is inserted at the front end. A groove 13 opening downward and outward is formed in the support 12, and the width t of the groove 13 is slightly larger than the capilano tube 8.

Numeral 14 is a nut having a threaded hole 15 located on the back side of the front wall of the control box 4 and threaded into the insertion columnar part 12A. It is slightly large.

For the thermostat I, with the back cover 16 of the control box 4 removed, move the nut 14 from the temperature sensing part 9 to the base of the character tube 8, and extend the temperature sensing part 9 from the hole 11 into the oil tank 2. The main body 7 is fixed to the inner surface of the control box 4, while the support 12 is passed through the opening of the groove 13 into the capillary tube 8 from outside the control box 4.
The capillary tube 8 is supported on the front wall of the control box 4 by screwing the nut 1-14 onto the insertion column 12A with the insertion column 12A inserted into the hole 11.

Since the groove 13 opens downward, oil adhering to the front wall of the control box 4 passes through the outer surface of the collar 12B and flows into the groove 13.
However, in order to completely prevent oil from entering the groove 13, fill the groove 13 with an oil-resistant sealing material so that the capillary tube 8 can be inserted into the center of the columnar part 12A. It also allows for positioning.

Due to this structure, when the thermostat is to be removed for repair or conversion, the removal work can be easily done by removing the Narrow I.14.

The present invention, configured as described above, is effective in closing the through hole when the temperature sensing part of the thermostat and the capillary tube are passed through the middle part of the front wall of the control box. If the control box was blocked, oil would enter the control box through the through hole due to deterioration of the rubber bushing, but this drawback can also be overcome with the present invention.

Moreover, the easily deformable capillary tube can be supported reliably, and the structure is effective in allowing easy removal and installation in the case of replacing or repairing the thermostat.
