Problems solved by technology

[0002] At present, the electric heaters used in air conditioners have no state detection feedback mechanism. The main controller of the air conditioner uses two relays to separately control the zero live wire of the electric heater. After the main controller controls the relay, the electric heater enters the working state. It only controls the pull-in of the relay, so it is impossible to know the real working status of the electric heater after the pull-in of the relay
Even if the electric heater fails, the air conditioner operating system will continue to control the electric heater, so when the electric heater fails abnormally, the user continues to use the working mode of turning on the electric heater, which will cause electrical safety problems or even serious accidents. the fire

Embodiment 1

[0019] Embodiment 1: A method for detecting and controlling the state of an electric heater.

[0020] A method for detecting and controlling the state of an electric heater is applied to an air conditioner, and the specific steps are as follows:

[0021] Before starting the electric heater self-inspection process, judge the historical fault state stored in the storage unit. This state defaults to no failure mode. When the user has a problem with the electric heater function, the fault information will be recorded. When the self-inspection process determines that the electric heater has historical fault records, it means that there is a problem with the electric heater body or the control circuit. Then, the self-inspection process is not run, so as to prevent safety problems caused by enabling the faulty electric heater during the self-inspection process. When a historical fault is detected and the user informs the after-sales personnel to replace the electric heater with a ...

Embodiment 2

[0029] Embodiment 2: A method for detecting and controlling the state of an electric heater during the operation of an air conditioner.

[0030] A method for detecting and controlling the state of an electric heater during the operation of an air conditioner, the specific steps are as follows:

[0031] Firstly, the running state information set by the current user is obtained, and then it is judged whether the electric heater function is turned on in the running state set by the air conditioner.

[0032] When the electric heater function does not need to be powered on in the running state set by the air conditioner or the electric heater function is disabled due to a fault, judge whether the electric heater status detection feedback current value is 0, if it is 0, it means that the air conditioner is at this time Normal operation, and then check every 1 minute until the user controls the air conditioner to turn off. If the detected current value of the electric heater is not ...

Embodiment 3

[0036] Embodiment 3: A device for detecting the state of an electric heater.

[0037] A state detection device for an electric heater, comprising a memory, a main controller, a live line control circuit, a zero line control circuit, a state detection feedback circuit and an electric heater, the main controller is used to receive the current data transmitted by the state detection feedback circuit and Send relevant control instructions, the live wire control circuit is used to control the pull-in and disconnection of the live-wire relay, the neutral wire control circuit is used to control the pull-in and disconnection of the neutral wire relay, and the state detection feedback circuit user feedback electric The working current of the heater, and the memory is used to store relevant detection data.

[0038] In this embodiment, compared with the traditional circuit block diagram, a state detection feedback circuit and a memory are added. The state detection feedback circuit pass...

Abstract

The invention provides an electric heater state detection control method, a computer readable storage medium and an air conditioner. A feedback current value when the electric heater works is detected, electric heater control circuit self-inspection and electric heater body self-inspection are carried out sequentially according to the feedback current value, and if any one of the electric heater control circuit and the electric heater body has a fault in the self-inspection process, a signal is sent to remind and stop work of the electric heater. The real working state of the electric heater is accurately judged through the current value, abnormity is found in time, the electrical safety problem caused by faults of the electric heater body and the electric heater control circuit can be prevented, the intelligent control level of the air conditioner is further improved, and influence caused by faults of the electric heater is reduced.
