Old people safe electric blanket

Abstract

The invention relates to an old people safe electric blanket. The old people safe electric blanket is foldable, convenient to store and safe and portable to use. 220 V alternating current electric supply is reduced to 36 V and 6V through a transformer, the 36 V is used for driving four pieces of independent-heating electric blanket bodies, the 6V is subjected to voltage stabilization to be turned into 5 V and then supplies a controller with power for utilization, humidity and temperature sensors are additionally installed for transmission to the controller, and the electric blanket is controlled to work or be powered off. The old people safe electric blanket can avoid accidents caused by the fact that the electric blanket is affected with damp happen to old people or patients not capable of conducting self-caring, and if the electric blank is affected with the damp, only part of the electric blanket is powered off, the other regions still work normally, so that users are prevented from getting cold. The old people safe electric blanket works under low voltage, the safety is guaranteed, through the partition of the electric blanket, humidity and temperature sensors are installed on the regions where accidents are prone to occurring, when damp reaches a certain degree, the power source in the region is automatically turned off, the other regions continue to work normally, and therefore the occurrence of accidents can be avoided effectively, and the old people continue to enjoy the pleasure brought by heating.

Description

1. Technical field [0001] The invention relates to a household appliance, in particular to a safety electric blanket for the elderly that uses a 36V safety voltage, is equipped with humidity and temperature sensors, and is divided into four pieces to generate heat independently. 2. Background technology [0002] If someone wets the bed, the electric blanket will get wet and accidents will occur. Since the electric blanket will get wet or soaked in water under special circumstances, the circuit must be cut off at the first time to avoid various accidents. Current electric blankets all use 220V power supply, which cannot automatically cut off the power supply when it is damp, which is very dangerous. It is a very happy thing for the elderly to use electric blankets, but due to various reasons, especially the elderly who cannot take care of themselves, it is easy for the working electric blankets to be damp or obviously flooded, causing electric shock or fire. 3.
