Specifically, when the operation of the warm air blower is safely prevented and controlled, the characteristic that heat in the warm air blower is rapidly accumulated to the top of the shell of the warm air blower in a short time under the condition that the fan stops operating is fully considered, the fan and the heater of the warm air blower are controlled to be closed by acquiring the first temperature close to the top of the shell in real time under the condition that the first temperature is larger than the preset temperature value, and the heater can be controlled to be closed in advance before the electric protection temperature value of the heater is triggered. Therefore, the control method disclosed by the embodiment can timely and effectively control the fan and the heater under the condition that the fan fails, avoids deformation of machine parts and fire disasters caused by high temperature in the fan heater for a short time, and ensures the use safety of the fan heater.
In one embodiment, the fan heater shown in this embodiment may be a floor type fan heater. For a floor type air heater, the air inlet of the air heater is usually disposed at the middle or lower part of the side wall of the housing, and the air outlet of the air heater is usually disposed at the upper part of the side wall of the housing. When the fan heater works normally, the temperature of the air inlet is equal to the indoor temperature of a room where the fan heater is located; when the fan of this electric fan heater broke down, because the fan can not in time follow the air outlet with the produced heat of heater in the electric fan heater and discharge to the heat can rise in the short time, and gather in the top of casing, at this moment, the first temperature that is close to the casing top is gathered to first temperature sensor of accessible, and obviously, the temperature value of casing headspace is not the same with the temperature value of electric fan heater air intake.
In another embodiment, the fan heater of this embodiment may be a wall-mounted fan heater. For a wall-mounted fan heater, an air inlet of the fan heater is usually disposed at a top of a sidewall of a housing of the fan heater, and an air outlet of the fan heater is usually disposed at a lower portion of the sidewall of the housing of the fan heater. When the fan heater works normally, the temperature of the air inlet is equal to the indoor temperature of a room where the fan heater is located; when the fan of the fan heater breaks down, the fan cannot discharge heat generated by the heater in the fan heater from the air outlet in time, so that the heat can rise in a short time and is accumulated at the top of the shell, at the moment, the first temperature close to the top of the shell can be collected by the first temperature sensor, and obviously, the temperature value of the top space of the shell is the same as or similar to that of the air inlet of the fan heater. Here, in order to accurately collect the temperature, the first temperature sensor may be specifically disposed in the middle of the air inlet of the warm air blower in the embodiment.

As shown in fig. 1, in order to further perform safety control on the operation of the warm air blower, in this embodiment, after the step 110 of collecting the first temperature near the top of the casing in the warm air blower, a step 130 of collecting the second temperature of the air outlet of the warm air blower is further provided, and when the second temperature is lower than the first temperature, the fan and the heater of the warm air blower are controlled to be turned off, and an early warning is performed.
Specifically, under the condition that the warm air blower normally operates to supply warm air to the indoor space, the first temperature close to the top of the casing in the warm air blower is the same as the temperature of the air inlet of the warm air blower, namely equal to the indoor temperature. The fan continuously discharges the heat generated by the heater out of the shell from the air outlet when in operation, so that the second temperature of the air outlet during normal air outlet is higher than the first temperature. When the fan in the warm air blower breaks down, the fan can not discharge the heat generated by the heater in the warm air blower from the air outlet in time, so that the heat can rise in a short time and is accumulated on the top of the shell, and the second temperature of the air outlet is lower than the first temperature. Therefore, the fan can be judged to be out of order under the condition that the second temperature is lower than the first temperature, so that the fan and the heater of the warm air blower can be controlled to be turned off in real time, deformation of machine parts and fire disasters caused by short-time high temperature in the warm air blower are avoided, and the use safety of the warm air blower is ensured.

Specifically, when the operation of the warm air blower is safely prevented and controlled, the characteristic that heat in the warm air blower is rapidly accumulated to the top of the shell of the warm air blower in a short time under the condition that the fan stops operating is fully considered, the fan and the heater of the warm air blower are controlled to be closed by acquiring the first temperature close to the top of the shell in real time under the condition that the first temperature is larger than the preset temperature value, and the heater can be controlled to be closed in advance before the electric protection temperature value of the heater is triggered. Therefore, the fan and the heater can be timely and effectively controlled under the condition that the fan breaks down, deformation of machine parts and fire disasters caused by high temperature in the fan heater for a short time are avoided, and the use safety of the fan heater is ensured.
Further, the safety protection control device of the fan heater shown in this embodiment further includes: and the second control module 230 is used for acquiring a second temperature of the air outlet of the warm air blower, controlling to close the fan and the heater of the warm air blower under the condition that the second temperature is less than the first temperature, and performing early warning.
Specifically, under the condition that the warm air blower normally operates to supply warm air to the indoor space, the first temperature close to the top of the casing in the warm air blower is the same as the temperature of the air inlet of the warm air blower, namely equal to the indoor temperature. Because the fan continuously discharges the heat generated by the heater out of the casing from the air outlet when the fan is running, the second temperature of the air outlet when the fan is in normal air outlet should be higher than the first temperature. And when the fan in the fan heater breaks down, the fan can not in time follow the air outlet with the produced heat of heater in the fan heater and discharge to the heat can rise in the short time, and gather in the top of casing, thereby makes the second temperature of air outlet be less than first temperature. Therefore, the fan can be judged to be out of order under the condition that the second temperature is lower than the first temperature, so that the fan and the heater of the warm air blower can be controlled to be turned off in real time, deformation of machine parts and fire disasters caused by short-time high temperature in the warm air blower are avoided, and the use safety of the warm air blower is ensured.
