Description

[Detailed description of the invention] In this invention, a control box that supports a heater, which is normally located in the oil tank, is rotatably attached to a pair of pillars fixed to the top surface of the main body having an oil tank, and is also placed inside the oil tank. The present invention relates to an electric fryer equipped with a manual reset type temperature sensing switch that cuts off power to the heater in response to a dangerous oil temperature being detected by the temperature sensing part.

A typical fryer of this type uses a thermostat to control the power supply to the heater to maintain the oil temperature within a certain range.

However, if the heater is continuously energized due to a malfunction of the thermostat, etc., the oil temperature will rise abnormally, which is dangerous, so a manual protection device is used to detect this abnormal oil temperature and forcibly cut off the power to the heater. A reset type temperature sensitive switch is provided.

This temperature-sensitive switch is designed so that once the energizing circuit to the heater is cut off, it will not turn on the energizing circuit to the heater again unless it is manually restored.

Conventionally, the operation part for manually resetting the temperature-sensitive switch was located in a visible location on the main body or control box, so there was a risk of the user operating it incorrectly. Even if the heater is started, the power supply to the heater is cut off again and the operation is repeated.

Therefore, the temperature-sensitive switch should be restored by a service person who has repaired it, and there is no need for any operation by the user.

In view of this, the present invention has been developed to prevent the user from erroneously operating a manual reset type temperature-sensitive switch that cuts off power to the heater when a dangerous oil temperature is detected, and to allow the user to reset the switch after repair. The purpose is to make it easy.

An embodiment of the present invention will be described below based on the drawings.

The main body 1 is provided with an oil tank 2 having an open top surface.
A sheathed heater 4 extending from the control box 3 is arranged in a meandering manner along the bottom surface.

The control box 3 is rotatably supported on the upper part of a pair of pillars 5 fixed to the upper surface 1A of the main body.

The oil tank 2 is also provided with a temperature-sensing section 6 that detects oil temperature, and a temperature-sensitive switch 7 that opens and closes contacts in response to the temperature-sensing state of the temperature-sensing section 6 is housed in the control box 3. .

This temperature-sensitive switch 7 controls the energization of the heater 4 so that the oil temperature is maintained at the temperature set by the adjustment dial 8 on the front surface 3A of the control box.

Furthermore, another temperature sensing part 9 for sensing the oil temperature is arranged in the oil tank 2,
a manual reset type temperature-sensitive switch that forcibly cuts off the power supply to the heater 4 in response to the temperature-sensing section 9 detecting a dangerous oil temperature higher than the highest temperature that can be set by the adjustment dial 8; 10 is housed in the control box 3.

This manual reset type temperature-sensitive switch 10 is activated when the temperature-sensitive switch 7 fails and the power to the heater 4 cannot be cut off and the oil temperature rises to an extremely dangerous temperature. If the power is cut off, the contacts will self-maintain in an open state even if the oil temperature drops, unless it is manually reset.

Then, point the return button IOA of the temperature-sensitive switch 10 housed in the control box 3 toward the bottom surface 3B of the control box, which normally faces the top surface 1A of the main body, and press the return button IOA on the bottom surface 3B of the box to remove the temperature-sensitive switch. A manual return operation section 11 for returning the switch 10 is provided.

The operating portion 11 is formed of, for example, a rubber material having elasticity.

As described above, in the normal use state of the present invention, as shown in FIG.
This prevents misuse, and after repairing a malfunction, holding the handle 12 and rotating the control box 3 as shown in FIG. can be restored and normal operation can be resumed.

As described above, the present invention houses a manual reset type temperature-sensitive switch that cuts off power to the heater when the oil temperature reaches a dangerous temperature in a rotatable control box, and also allows manual reset operation of the temperature-sensitive switch. Since this is an electric fryer, the control box is located on the bottom of the control box, which faces the top of the main unit and is not visible to the user.This prevents misuse by the user, and after repairs are made, the control box can be rotated to detect temperature. This provides a practical advantage in that the return operation of the switch can be easily performed.
