Problems solved by technology

[0002] At present, in places such as hotels, guesthouses, catering and leisure, mobile electric water heaters are often used to sterilize and sterilize items such as towels used by guests with high-temperature steam. However, the existing mobile electric water heaters lack Manual observation is still used to add water after watering. The measures are relatively primitive and simple, so there is almost no water shortage protection device. It is prone to the problem of not adding water in time after water shortage, which will cause the water heater to burn out, and the safety is poor.

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] see figure 1 , in this embodiment, the partition 2 of the mobile electric water heater 1 is used to place items such as towels that need to be sterilized, and the electric heating tube 3 is installed at the bottom of the water heater. As can be seen from the figure, the water level sensor 4 is installed in the water tank 5, and the signal Inductor 17 is installed in the position corresponding to water level sensor 4 outside the bottom of water tank 5 . The control circuit 18 is installed outside the bottom of the water heater.

[0016] see image 3 The water level sensor 4 includes a hook 401, a sleeve 402 is fixed in the middle of the hook 401, a sliding link 403 is arranged in the sleeve 402, a magnet 404 is fixed at the bottom of the sliding link 403, and is located between the sleeve 402. Upper and lower sliding links 403 are pro...

Abstract

The invention belongs to the technical field of electric equipment, particularly relating to a no-water protection device of a movable electric water heater. The no-water protection device of a movable electric water heater comprises a water level sensor which is installed in the movable electric water heater; the water level sensor is connected with a signal inductor, the signal inductor is connected with the control circuit, and the control circuit controls the on and off and no-water alarm of the electrical heated tube of the movable electric water heater. When the water level is lower than a set safety line, the signal inductor of the no-water protection device of the invention is switched on the circuit of an alarming part, and a music chip and a loudspeaker work to achieve the purpose of giving an alarm; and meanwhile, the electrical heated tube circuit is in the state of power failure, so that the electrical heated tube stops working and does not heat water in the water tank. The invention has simple structure and is practical, safe and reliable.
