In this embodiment, filtering component 4 sets up in the water inlet position department of inlet tube 2, and first turbidity sensor 5 is located the inlet tube and keeps away from the position department in the water inlet to do benefit to the outside water supply after filtering and carry out water quality testing, and then effectively improve water quality testing's precision. In this embodiment, the communication module is at least one of a wireless communication module and/or a wired communication module, where the wireless communication module may be a WIFI module, a bluetooth module, or an infrared module, but is not limited to the above wireless communication module, and other more suitable wireless communication modules may be selected according to actual needs.
Example two:
as shown in fig. 2, the present embodiment provides a control method for monitoring water quality of a water heater, which is characterized in that the control method for monitoring water quality of a water heater includes the first embodiment, the first turbidity sensor is used for detecting the turbidity of the water quality of the water inlet pipe to obtain the water quality of the external water supply and the use condition of the filter assembly, so as to send an alarm message to remind a user of treating the water quality problem at the water inlet pipe, i.e., to remind the user of whether the water quality of the external water supply is qualified and whether the filter assembly needs cleaning and maintenance, in order to further confirm whether the current water quality is qualified or not, the second turbidity sensor is used for detecting the turbidity of the water quality of the water outlet pipe to obtain the scale condition of the heat exchange system, so as to send an alarm message to remind the user of treating the scale problem on the heat exchange system, i., therefore, the source points of the water heater, which mainly influence the water quality problem, can be quickly obtained, so that a user can perform corresponding treatment work according to the detected source points of the water heater, the design is reasonable, whether the current water quality is qualified or not is visually shown to the user through real-time monitoring of the turbidity of the water quality, and the user is prompted to maintain the water heater if the current water quality is unqualified.
The control method for monitoring the water quality of the water heater comprises the following steps:
and step S101, starting the water heater to operate for a certain time.
In this embodiment, start the water heater and carry out the back of working and count down according to the operation time of predetermineeing, detect the current quality of water condition of water heater again after through making the water heater operation certain time to guarantee the stable circulation of rivers, and then effectively reduce water quality testing's error. The preset operation time in this embodiment is preferably 3 minutes, but may be set to other more suitable time values according to actual requirements.
And S102, detecting the current water quality condition at the water inlet pipe to obtain a water inlet turbidity value.
In this embodiment, the water heater operates after the definite time, start first turbidity sensor and carry out the first detection to the current quality of water condition of inlet tube department promptly after the countdown finishes to interval preset time detects the current quality of water condition of inlet tube department in order to obtain a plurality of actual turbidity values respectively, reject minimum and maximum value in a plurality of actual turbidity values, then calculate the average value of remaining a plurality of actual turbidity values in order to obtain into water turbidity value, thereby effectively reduce water quality testing's error, and then can further improve water quality testing's precision. The preset time is preferably 5S in this embodiment, but is not limited to the above time value, and may be selected as another more suitable time value according to the market demand. In this embodiment, the plurality of actual turbidity values are preferably 5 actual turbidity values, but are not limited to the above values, and other more suitable values may be selected according to actual requirements.
Step S103, judging whether the turbidity value of the inlet water is greater than or equal to a first preset turbidity value or not;
if so, sending alarm information to remind a user to treat the water quality problem at the water inlet pipe;
if not, detecting the current water quality condition at the water pipe to obtain an effluent turbidity value.
In this embodiment, if the incoming water turbidity value is smaller than the first preset turbidity value, the second turbidity sensor is started to detect the current water quality condition at the water outlet pipe, and in this embodiment, the first preset turbidity value is preferably 3NTU, but is not limited to the above-mentioned set value, and may also be selected as another more suitable set value according to actual requirements.
Step S104, judging whether the difference value between the inlet water turbidity value and the outlet water turbidity value is less than or equal to a second preset turbidity value;
if so, judging whether the effluent turbidity value is greater than or equal to a third preset turbidity value;
if not, alarm information is sent out to remind a user to treat the scale problem on the heat exchange system.
In this embodiment, if the difference of the turbidity value of intaking and the turbidity value of leaving water is greater than the preset turbidity value of second, then conclude that heat exchange system inner wall scale deposit is serious and great to the influence of quality of water condition, consequently send alarm information in order to remind the user to carry out the scale of clean maintenance in order to get rid of heat exchange system water tank inner wall to the water heater heat exchanger. The second preset turbidity value in this embodiment is preferably 0.2NTU, but is not limited to the above setting value, and may be selected as another more suitable setting value according to actual requirements. The third preset turbidity value is preferably 3NTU, but is not limited to the above setting value, and may be selected as other more suitable setting values according to actual requirements.
Step S105, judging whether the effluent turbidity value is greater than or equal to a third preset turbidity value;
if so, sending alarm information to remind a user to treat the water quality problem at the water inlet pipe;
if not, judging whether the effluent turbidity value is greater than or equal to a fourth preset turbidity value and less than or equal to a fifth preset turbidity value.
In this embodiment, if the turbidity value of the outlet water is greater than or equal to the third preset turbidity value, the water quality at the inlet pipe is considered to be unqualified, and the main problem affecting the unqualified water quality is that the quality of the externally supplied water is unqualified or the filter assembly needs to be cleaned and replaced due to too long service time. The fourth preset turbidity value in this embodiment is preferably 1NTU, but is not limited to the above setting value, and may be selected as another more suitable setting value according to actual requirements. The fifth preset turbidity value is preferably 3NTU, but is not limited to the above setting value, and may be selected as other more suitable setting values according to actual requirements.
Step S106, judging whether the effluent turbidity value is greater than or equal to a fourth preset turbidity value and less than or equal to a fifth preset turbidity value;
if so, judging that the current water quality of the water heater is excellent and informing a user;
if not, the current water quality condition of the water heater is judged to be qualified, and a user is informed.
In this embodiment, the water heater passes through communication module with the current quality of water condition and transmits to outside intelligent terminal on or directly inform the user through the control panel of water heater to make whether the current quality of water of user's intuitional perception is qualified, and then improved user's use and experienced.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
