In this embodiment, the temperature detector 3, the temperature fuse 4 and the temperature controlled switch 5 are all used for controlling the safe use of the heater 2. The temperature detector 3 and the temperature control switch 5 are electrically connected with the control circuit board, and the temperature fuse 4 is electrically connected in the power supply circuit of the heater 2.
The temperature detector 3 may be a temperature sensor of the prior art, such as a thermocouple. When the high-temperature catalytic deodorization is carried out, the heating temperature in the pipe body 1 needs to reach 500 ℃. The temperature detector 3, the temperature fuse 4, and the temperature controlled switch 5, which can withstand such high temperatures, are not only expensive but also have a short service life. The controllable temperature ranges of the existing temperature detection device, the temperature fuse 4 and the temperature control switch 5 are usually below 300 ℃, although the thermocouple used as the temperature detection device can measure the temperature of 500 ℃, the service life of the thermocouple at the temperature is greatly reduced, and meanwhile, the thermocouple cannot be installed at the center of the pipe body 1.
In order to realize high-temperature detection by using a common temperature detector 3, a temperature fuse 4 and a temperature controlled switch 5, and prolong the service life of the components. In this embodiment, the temperature detector 3 is connected to the pipe body 1 via the heat transfer member 6, and the temperature detector 3 is fitted to the heat transfer member 6. Specifically, the heat transfer member 6 is a column-shaped body matched with the pipe body 1, and the heat transfer member 6 is fixedly connected to the end cover 13 at the upper end of the pipe body 1 by being connected to a flange plate (61). In this operation, the heat in the pipe body 1 is transferred through the heat transfer member 6, but the temperature of the heat transfer member 6 is much lower than that of the central portion of the pipe body 1, and the temperature of the heat transfer member 6 has a fixed relationship with the temperature of the central portion of the pipe body 1. That is, if the turn-off temperature of the heater 2 is set to 500 c, the temperature on the corresponding heat transfer member 6 is generally 300 c, so that the control circuit board controls the heater 2 to be turned off when the temperature detected by the temperature detecting means reaches 300 c.

When the central temperature of the tube body 1 is controlled to be about 500 ℃, the temperature of the temperature control switch 5 is about 150 ℃ and the temperature of the temperature fuse 4 is about 170 ℃ during normal work. Therefore, a temperature control switch 5 at 160 ℃ and a temperature fuse 4 at 180 ℃ can be selected. When the temperature control of the temperature detection device is invalid or delayed, the heating pipe can continue to heat, the temperature rises, the temperature at the temperature control switch 5 rises, when the temperature rises to 160 ℃, the temperature control switch 5 is switched off, and the control circuit board controls the heater 2 to be switched off to stop heating. After cooling, when the temperature at the temperature control switch 5 is reduced to below 150 ℃, the temperature control switch 5 is closed, and the control circuit board controls the heater 2 to perform heating operation again.
When the temperature control switch 5 is also failed, the temperature continuously rises, and when the temperature of the temperature fuse 4 reaches 180 ℃, the fuse is fused, and the heating pipe is powered off to stop heating.
The high-temperature protection realized by the temperature detection device and the temperature control switch 5 is recoverable protection, and the temperature fuse 4 is unrecoverable protection. When the temperature fuse 4 is fused, the fault can be reported under control to remind a user.
The thermal catalytic device of the garbage disposer can realize multiple high-temperature protection when working at high temperature, not only can realize software high-temperature protection, but also can realize hardware high-temperature protection, and further adopts two different working mechanisms to realize high-temperature protection, so that the reliability of the high-temperature protection of the thermal catalytic work of the garbage disposer is higher.
And when carrying out temperature measurement in body 1, need not directly detect the temperature in high temperature region through the setting to detecting the temperature part position, improved detection device's life-span for detection device's job stabilization nature is more reliable.
