Aiming at the problems existing in the prior art, the purpose of the utility model is to provide an electric water heater which can prompt the service life of the filter element.

In order to achieve the above object, the utility model adopts the following technical solutions.

An electric water heater with a service life prompt for a filter element, comprising: an inner tank, a water inlet pipe and an outlet pipe arranged on the inner tank, a filter device arranged on the water inlet pipe, a controller and a display operator; The water outlet end of the filter device is provided with a flow sensor, and the signal detected by the flow sensor is transmitted to the controller and displayed on the display operator after being converted by the controller.

As a further description of the above solution, the controller is a single-chip microcomputer.

As a further description of the above solution, the display operator includes a display and a reset button.

As a further description of the above solution, a prompt light is connected to the controller, and the prompt light is integrated on the display operator.

As a further description of the above solution, a power-off clock running module is connected to the controller.

As a further description of the above solution, the controller and the display operator are integrated together.

As a further description of the above solution, the controller and display operator are installed on the inner shell.

Compared with the prior art, the electric water heater provided by the utility model has the following beneficial effects:

1. By setting a flow sensor at the water outlet of the filter device, and using the controller to convert the flow signal into a service life signal and displaying it on the display operator, the purpose of prompting the user to replace the filter element regularly is achieved to ensure the quality of bathing water.

2. It only needs to add a flow sensor at the water outlet of the filter device to achieve the purpose of life detection of the filter device. The structure is reasonable, the use is convenient, and the detection is accurate.

Figure 2 shows the principle block diagram of the service life prompt of the filter element.

Explanation of reference signs:

1. Inner tank, 2. Water inlet pipe, 3. Water outlet pipe, 4. Filter device, 5. Flow sensor, 6. Controller, 7. Display operator, 8. Warning light, 9. Power-off clock operation module.

Detailed ways

In order to facilitate those skilled in the art to better understand the essence of the utility model, the specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Fig. 1-Fig. 2, an electric water heater with service life reminder of the filter element includes: an inner tank 1, a water inlet pipe 2 and an outlet pipe 3 arranged on the inner tank 1, and a filter device arranged on the water inlet pipe 2 4. Flow sensor 5, controller 6 and display operator 7.

Wherein, the flow sensor 5 is arranged at the water outlet end of the filter device 4, the water flow signal detected by the flow sensor 5 is transmitted to the controller 6, and after being converted by the controller 6, the service life of the filter element is displayed on the display operator 7 . In this way, the user can be informed of the use status of the filter device of the electric water heater, and the user can be prompted to replace the filter element of the filter device in time, so as to ensure that the user can continue to use healthy and clean hot water.

In this embodiment, the controller 6 is preferably a single-chip microcomputer, and the display operator 7 preferably includes a display and a reset button, so that the user can manually reset the display operator after replacing the filter element, which is convenient and practical. In order to simplify the installation structure, it is preferable that the controller 6 and the display operator 7 are integrated and installed on the shell of the inner tank 1 .

Further, in order to facilitate the user's observation and recognition, a prompt light 8 is connected to the controller, and the prompt light 8 is integrated on the display operator 7 .

Furthermore, in order to realize intermittent power failure, the time system can continue to run and be memorized, a power-off clock running module 9 is connected to the controller, and the main core of the power-off clock running module 9 is a clock chip and a large capacity Energy storage capacitor.

Compared with the prior art, the electric water heater provided in this embodiment evaluates the use status of the filter element of the electric water heater according to the parameters of water inflow, digitizes the feedback information, and displays it on the display operator, so that the user can understand the use status of the filter element of the filter device of the electric water heater. It can effectively prevent the filter element from being used for too long and cause secondary pollution, and it is convenient for the user to replace the filter element of the electric water heater regularly to ensure the user's healthy bathing.

The above specific embodiments have described the essence of the utility model in detail, but the protection scope of the utility model cannot be limited by this.
