Electric water heater and tumble prompting method and device based on electric water heater in bathroom

Abstract

The invention discloses an electric water heater and a tumble prompting method and device based on the electric water heater in a bathroom. The method comprises the following steps that a radar modulearranged on the electric water heater is started to detect human body motions in the bathroom, and obtains a detection result of whether there is a human body motion in the bathroom; continuous timewhen there is no human body motion in the bathroom is obtained according to the detection result; whether the continuous time is greater than a first time threshold is determined; and if YES, the electric water heater emits a tumble alarm prompt. Via the method, tumble of a user in the bathroom can be detected timely and accurately via radar detection, the reliability and comfortableness are higher, alarm prompt is emitted timely when the user tumbles, and the personal safety of the user is guaranteed effectively.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a fall warning method based on an electric water heater in a bathroom, a fall warning device based on an electric water heater in a bathroom, and an electric water heater. Background technique [0002] In people's daily life, the environment in the bathroom is relatively humid compared with other indoor environments, and it is very easy for the user to fall, and the user is not easy to be found by his family after the user falls. As a common household appliance in the bathroom, the water heater can be well applied in the bathroom and can detect whether the user has fallen. [0003] Currently, a user usually uses a wearable fall detection device to detect whether the user falls during the bathing process. The device uses a multi-axis acceleration sensor to detect whether the user has fallen, and transmits the signal through a wireless communication module ...

AI Technical Summary

Problems solved by technology

The device uses a multi-axis acceleration sensor to detect whether the user has fallen, and transmits the signal through a wireless communication module (such as Bluetooth). This wearable fall detection device has some problems, for example, the waterproof level is not enough to easily cause short circuit of the device, Insufficient comfort and low detection accuracy

In addition, light sensors (such as laser and infrared) can also be installed in the bathroom to detect whether a user has fallen in the bathroom. However, these devices have some problems, such as low fall detection accuracy, large equipment, and large dead angles.
