Commonly used infrared remote controls are not remote operation, because the user of the infrared remote controls is at the working site of the appliance, and can view the reaction and working status of the appliance after the infrared remote controls is operated in real time. If the infrared remote controls is part of a communication system, a sound control system or a bus system, in this case, the initiator of control mainly completes the control through the communication system, the sound control system or the bus system. Generally speaking, the initiator of control sends instructions to a separate infrared controller through the communication system, the sound control system or the bus system, and then the infrared controller transmits infrared remote control information to the appliance to complete the operation; in this case, this set of control systems can be considered as remote operation. Example: The infrared remote controller used for ordinary air conditioners is not remote operation; there is a centralized controller on the market currently that can be placed in the core position of a building. Users can control it to transmit infrared signals through WIFI. The transmitted infrared signals can control any electrical products in the room. This is a remote operation.

electronic circuit: circuit incorporating at least one electronic component. The standard references electronic circuits in clause 19.11, clause 19.11.1, and clause 22.5. These requirements are additional to those for electronic circuits. The standard recognizes that electronic circuits alone cannot provide adequate protection. Electronic circuits may be susceptible to interference and malfunction, or they may be…
portable appliance: appliance that is intended to be moved while in operation or an appliance, other than a fixed appliance, having a mass less than 18 kg. This item is relatively easy to understand. Products that are less than 18kg are relatively light, so they are easy to move during operation, including humidifiers, fans, air…
all-pole disconnection: disconnection of both supply conductors by a single initiating action or, for multi-phase appliances, disconnection of all supply conductors by a single initiating actionNOTE For multi-phase appliances, the neutral conductor is not considered to be a supply conductor. Single-phase power: An AC power system composed of one live wire and one neutral wire.Three-phase…
self-resetting thermal cut-out: thermal cut-out that automatically restores the current after the relevant part of the appliance has cooled down sufficiently In the definition there is a clear mention, when the temperature is cooled to a certain degree, in fact, its intention is to control the temperature is not too high, when the temperature is…
