Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-5, the dry-heating preventing water purifying drinking machine comprises a shell 1 and a raw water tank 2, wherein a filter element 3, a pure water tank 4 and an electric heater 5 are arranged in the shell 1, and a water-vapor separator 6 is arranged on the shell 1. In the embodiment, the shell 1 is internally provided with the protective shell 7, and the filter element 3 is positioned in the protective shell 7, so that the filter element 3 serving as a core component is better protected. In this embodiment, the bottom surface of the housing 1 simultaneously forms the bottom surface of the raw water tank 2, so that the structure is more compact.
The raw water tank 2 is communicated with the water inlet of the filter element 3 through a water inlet pipeline 8, the raw water tank 2 is communicated with the waste water outlet of the filter element 3 through a water return pipeline 9, the pure water outlet of the filter element 3 is communicated with the pure water tank 4 through a water outlet pipeline 10, the pure water tank 4 is communicated with the electric heater 5 through a pure water pipeline 11, the electric heater 5 is communicated with the water-vapor separator 6, and hot water finally flows out after being subjected to water-vapor separation in the water-vapor separator 6.
The water inlet pipeline 8 is provided with a first water pump 12, and the pure water pipeline 11 is provided with a second water pump 13.
The shell is also internally provided with an MCU controller connected with the electric heater 5, the water inlet pipeline 8 is also provided with a flow meter 14, the electric heater 5 is provided with a temperature probe, the flow meter 14 and the temperature probe are both in signal connection with the MCU controller, and the MCU controller controls whether the electric heater works or not according to signals provided by the flow meter 14 and the temperature probe.
The working principle of the utility model is as follows: the flow meter 14 and the temperature probe are in signal connection with the MCU controller, wherein the flow meter 14 detects water flow, when the water flow of inlet water is small to a certain extent, the water inlet flow is very small, the water provided by the raw water tank 2 is very little, and at the moment, if the heating is continued, the dry burning phenomenon is likely to occur, so that the flow meter 14 can find the time when the dry burning is likely to occur in time, further send a signal to the MCU controller, and the MCU controller instructs the electric heater to stop heating, thereby effectively preventing the dry burning phenomenon; meanwhile, if the temperature probe detects abnormal high temperature, the dry burning phenomenon can be judged to occur, and then a signal is sent to the MCU controller, and the MCU controller instructs the electric heater to stop heating.
In this embodiment, the temperature probes include a first temperature probe 15 and a second temperature probe 16, the first temperature probe 15 is located at the upper end of the electric heater 5, the second temperature probe 16 is located at the lower portion of the electric heater 5, and two temperature probes are arranged to detect the temperature more accurately.
