Problems solved by technology

[0006] As mentioned above, since the remote controller is operated, the signal that can be transmitted and received wirelessly is limited to a certain range according to the distance from the home appliance and the angle to the home appliance, so the farther the distance from the home appliance is, the weaker the signal strength is. Even the situation that it cannot be transmitted normally
Therefore, when the home appliance cannot be remotely controlled, there is a problem that the user may mistakenly think that the home appliance is malfunctioning, etc.

Abstract

A domestic appliance control system with remote controller comprises remote controller and domestic appliance control system. It is featured as enabling user to know receiving scope of remote controller and enabling to stop movement exceeding said receiving scope when remote controller is used to control operation of domestic appliance.

Description

technical field [0001] The invention relates to a household appliance control system with a remote controller and a control method thereof, especially when the remote controller is powered on, it can continuously generate a specific signal, judge its receiving range according to whether the specific signal is received, and judge the A household appliance control system with a remote controller and a control method thereof, which output a warning tone or a message to the outside within the receiving range of the remote controller. Background technique [0002] Generally speaking, the remote control is to control the household appliances by generating operation signals to the household appliances fixedly arranged in a certain position and performing remote transmission. At present, the development trend of household appliances makes almost all household appliances have the function of remote control for remote adjustment. [0003] After the above-mentioned remote control is o...
