[0068] The description should not constitute an unnecessary limitation due to the use of such a prefix. Furthermore, in the description of this embodiment, unless otherwise stated, "multiple" means two or more.

[0069] In this embodiment of the disclosure, the collection, storage, use, processing, transmission, provision, and disclosure of user personal information comply with relevant laws and regulations and do not violate public order and good morals.

[0070] Example 1

[0071] Figure 1 This is a flowchart of a testing method for a water purifier provided in Embodiment 1 of this disclosure, as follows: Figure 2 As shown, the water purifier includes a heating element 11 and at least two probes disposed at the front end of the heating element 11, such as... Figure 1 As shown, the detection method includes:

[0072] Step 101: Obtain at least two water level values ​​detected by at least two probes;

[0073] Step 102: Obtain the maximum water level value from at least two water level values;

[0074] Step 103: Determine whether the maximum water level is greater than the minimum preset water level and less than the maximum preset water level. If not, proceed to step 104.

[0075] In this embodiment, the minimum water level value when the water volume between the probes in the pipeline is insufficient is obtained through experimental testing, and the maximum water level value when the probes in the pipeline are filled with water is obtained through experimental testing, which is the maximum preset water level value Δmax.

[0076] It should be noted that when the water level between the probes in the pipeline is less than the minimum preset water level value Δmin, the heating pipe will dry out and spew steam due to insufficient water supply.

[0077] Step 104: Determine if the water supply to the water purifier is abnormal. Set the abnormal flag at at least two probes to 1, output a water shortage warning message, and control the heating element to shut down.

[0078] In this embodiment, when it is determined that the water supply to the water purifier is abnormal, the abnormal flag bits at at least two probes are set to 1, and a water shortage warning message is output to remind the user that the machine is abnormal and needs to be repaired. The heating element is then turned off, and the water purifier dispenses room temperature water.

[0079] In an optional embodiment, the detection method further includes:

[0080] Step 105: If the maximum water level is determined to be greater than the minimum preset water level but less than the maximum preset water level, then the water supply of the water purifier is determined to be normal. Set the abnormal flags at at least two probes to 0 and control the heating element to turn on.

[0081] In this embodiment, when it is determined that the water supply to the water purifier is normal, the abnormal flag bits at at least two probes are set to 0, and the heating element is turned on. At this time, the water purifier produces hot water.

[0082] In an alternative embodiment, such as Figure 2 As shown, the water purifier also includes a hot water inlet valve 12, a hot water pump 13, a first temperature sensor 14, a second temperature sensor 15, a water outlet valve 16, an ultraviolet sterilizer 17, a wastewater valve 18, a membrane chromatograph 19, a booster pump 20, a pre-filter 2111, a post-filter 2112, and a whole-machine inlet valve 2113. When at least two probes are used, the maximum water level value includes a first maximum water level value. The two probes include a first probe and a second probe. The first probe and the second probe are located between the hot water inlet valve 12 and the hot water pump 13, or between the hot water pump 13 and the heating element 11. Step 101 includes:

[0083] Obtain the first water level value detected by the first probe and the second water level value detected by the second probe;

[0084] Step 102 includes:

[0085] The first maximum water level value is obtained from the first water level value and the second water level value;

[0086] Step 103 includes:

[0087] Determine whether the first maximum water level value is greater than the minimum preset water level value and less than the maximum preset water level value.

[0088] In an alternative embodiment, such as Figure 2 As shown, the water purifier also includes a hot water inlet valve 12 and a hot water pump 13. When there are at least two probes and four probes, the maximum water level value includes a first maximum water level value and a second maximum water level value, for example, such as... Figure 2As shown, the four probes include a first probe A1, a second probe A2, a third probe B1, and a fourth probe B2. The first probe A1 and the second probe A2 are positioned between the hot water inlet valve 12 and the hot water pump 13, and the third probe B1 and the fourth probe B2 are positioned between the hot water pump 13 and the heating element 11. Figure 3 As shown, the detection method also includes:

[0089] Step 201: Obtain the first water level value detected by the first probe and the second water level value detected by the second probe;

[0090] Step 202: Obtain the first maximum water level value between the first water level value and the second water level value;

[0091] Step 203: Determine whether the first maximum water level is greater than the minimum preset water level and less than the maximum preset water level. If not, proceed to step 204; if yes, proceed to step 205.

[0092] Step 204: Determine that the water supply to the water purifier is abnormal, set the abnormal flags at the first and second probes to 1, output a water shortage warning message, and control the heating element to shut down.

[0093] Step 205: Set the abnormality flag bits at both the first and second probes to 0;

[0094] Step 206: Obtain the third water level value detected by the third probe and the fourth water level value detected by the fourth probe;

[0095] Step 207: Obtain the second maximum water level value between the third and fourth water level values;

[0096] Step 208: Determine whether the second maximum water level is greater than the minimum preset water level and less than the maximum preset water level. If not, proceed to step 209; if yes, proceed to step 210.

[0097] Step 209: Determine that the water supply to the water purifier is abnormal, set the abnormal flags at the third and fourth probes to 1, output a water shortage warning message, and control the heating element to shut down.

[0098] Step 210: Determine whether the abnormal flag bits at the first and second probes, as well as the abnormal flag bits at the third and fourth probes, are all set to 0. If yes, proceed to step 211; if no (i.e., if it is determined that at least one of the abnormal flag bits at the first, second, third, and fourth probes is not set to 0), proceed to step 212.

[0099] Step 211: Confirm that the water supply to the water purifier is normal, and turn on the heating element;

[0100] Step 212: Determine if there is an abnormality in the water supply of the water purifier's pipeline, and shut down the heating element.

[0101] In an optional embodiment, prior to step 101, the detection method further includes:

[0102] Determine whether a hot water command has been received. If so, proceed with the step of obtaining at least two water level values ​​detected by at least two probes.

[0103] In the specific implementation process, when water in the pipeline covers the first probe A1 and the second probe A2, the main control board of the water purifier can read the first maximum water level value ΔA between the first probe A1 and the second probe A2. It should be noted that the magnitude of this value (i.e., the first maximum water level value ΔA) is proportional to the area of ​​the water contact probe. When water in the pipeline covers the third probe B1 and the fourth probe B2, the main control board can read the second maximum water level value ΔB between the third probe B1 and the fourth probe B2. It should be noted that the magnitude of this value (i.e., the second maximum water level value ΔB) is proportional to the area of ​​the water contact probe.

[0104] Based on the above data, when a user takes cold water, the water purifier valve is closed and the probe logic detection is not initiated; when a user takes hot water (i.e., a hot water take command is received), it is determined whether the first maximum water level value ΔA and the second maximum water level value ΔB are within the range of Δmin to Δmax. If the first maximum water level value ΔA is not within the range, the abnormal flag bit Aflg at the first probe A1 and the second probe A2 is set to 1, and a water shortage warning is displayed; otherwise, the abnormal flag bit Aflg at the first probe A1 and the second probe A2 is cleared (i.e., the abnormal flag bit Aflg at the first probe A1 and the second probe A2 is set to 0).

[0105] If the second maximum water level value ΔB is not within the range of Δmin to Δmax, the abnormal flag bit Bflg at the third probe B1 and the fourth probe B2 is set to 1, and a water shortage warning is displayed at the same time; otherwise, the abnormal flag bit Bflg at the third probe B1 and the fourth probe B2 is cleared (i.e., the abnormal flag bit Bflg at the third probe B1 and the fourth probe B2 is set to 0).

[0106] Determine whether the abnormal flag bit Aflg at the first probe A1 and the second probe A2 is 0 and whether the abnormal flag bit Bflg at the third probe B1 and the fourth probe B2 is 0. If yes, it means that the water supply in the pipeline is normal, the heating is turned on normally, and the hot water required by the user is produced. If no, it means that the water supply in the pipeline is abnormal, the heating is not turned on, and room temperature water is produced.

[0107] This embodiment ensures that the heating element will not dry-burn under abnormal conditions in the pipeline and provides the user with room temperature water. At the same time, the alarm mechanism can also notify the user of machine malfunctions that require maintenance, ensuring the user's subsequent experience. In addition, this embodiment adopts a design with at least two probes, providing double protection and preventing the risk of single failure, making it more reliable, stable, and low-cost.

[0108] This embodiment uses at least two probes at the front end of the heating element to detect the water level in the water purifier's pipeline. Specifically, the maximum water level value is obtained from at least two water level values ​​detected by the probes. If the maximum water level value is determined to be outside the range of the minimum and maximum preset water level values, an abnormal water supply to the water purifier's pipeline is identified. The abnormality flags at both probes are set to 1, a water shortage warning message is output, and the heating element is shut down. This method, based on at least two probes, enables water shortage detection, preventing the failure of any single probe from affecting the detection and mitigating the risk of the heating element burning out. Furthermore, the use of probes is cost-effective, reliable, and stable.

[0123] The second acquisition module 22 is used to acquire a first maximum water level value from the first water level value and the second water level value;

[0124] The first judgment module 23 is used to determine whether the first maximum water level value is greater than the minimum preset water level value and less than the maximum preset water level value.

[0125] In an alternative embodiment, such as Figure 2 As shown, the water purifier also includes a hot water inlet valve 12 and a hot water pump 13. When there are at least two probes and four probes, the maximum water level value includes a first maximum water level value and a second maximum water level value, for example, such as... Figure 2 As shown, the four probes include a first probe A1, a second probe A2, a third probe B1, and a fourth probe B2. The first probe A1 and the second probe A2 are positioned between the hot water inlet valve 12 and the hot water pump 13, and the third probe B1 and the fourth probe B2 are positioned between the hot water pump 13 and the heating element 11.Figure 4 As shown, the detection device also includes: a third control module 26, a fourth control module 27, a third acquisition module 28, a fourth acquisition module 29, a second judgment module 30, a fifth control module 31, a third judgment module 32, and a sixth control module 33;

[0126] The first acquisition module 21 is used to acquire the first water level value detected by the first probe and the second water level value detected by the second probe.

[0127] The second acquisition module 22 is used to acquire a first maximum water level value from the first water level value and the second water level value;

[0128] The first judgment module 23 is used to determine whether the first maximum water level value is greater than the minimum preset water level value and less than the maximum preset water level value. If not, the third control module 26 is called; if yes, the fourth control module 27 is called.

[0129] The third control module 26 is used to determine the abnormal water supply of the water purifier's pipeline, set the abnormal flag bits at the first and second probes to 1, output a water shortage warning message for the pipeline, and control the heating element to shut down.

[0130] The fourth control module 27 is used to set the abnormal flag bits at both the first and second probes to 0;

[0131] The third acquisition module 28 is used to acquire the third water level value detected by the third probe and the fourth water level value detected by the fourth probe;

[0132] The fourth acquisition module 29 is used to acquire the second maximum water level value between the third water level value and the fourth water level value;

[0133] The second judgment module 30 is used to determine whether the second maximum water level value is greater than the minimum preset water level value and less than the maximum preset water level value. If not, the fifth control module 31 is called; if yes, the third judgment module 32 is called.

[0134] The fifth control module 31 is used to determine the abnormal water supply of the water purifier's pipeline, set the abnormal flag bits at the third and fourth probes to 1, output a water shortage warning message for the pipeline, and control the heating element to shut down;

[0135] The third judgment module 32 is used to determine whether the abnormal flag bits at the first and second probes, as well as the abnormal flag bits at the third and fourth probes, are all set to 0. If so, the sixth control module 33 is called.

[0136] The sixth control module 33 is used to determine that the water supply to the water purifier is normal and to control the heating element to turn on.

[0137] In an alternative embodiment, such as Figure 4As shown, the detection device also includes: a seventh control module 34;

[0138] The seventh control module 34 is used to determine that the water supply of the water purifier is abnormal if it is determined that at least one of the abnormal flag bits of the first probe, the second probe, the third probe and the fourth probe is not set to 0, and to control the heating element to shut down.

[0139] In an alternative embodiment, such as Figure 4 As shown, the detection device also includes: a fourth judgment module 35;

[0140] The fourth judgment module 35 is used to determine whether a hot water retrieving command has been received. If so, the first acquisition module 21 is called.

[0141] The first acquisition module 21 is used to perform the step of acquiring at least two water level values ​​detected by at least two probes.

[0142] In the specific implementation process, when water in the pipeline covers the first probe A1 and the second probe A2, the main control board of the water purifier can read the first maximum water level value ΔA between the first probe A1 and the second probe A2. It should be noted that the magnitude of this value (i.e., the first maximum water level value ΔA) is proportional to the area of ​​the water contact probe. When water in the pipeline covers the third probe B1 and the fourth probe B2, the main control board can read the second maximum water level value ΔB between the third probe B1 and the fourth probe B2. It should be noted that the magnitude of this value (i.e., the second maximum water level value ΔB) is proportional to the area of ​​the water contact probe.

[0143] Based on the above data, when a user takes cold water, the water purifier valve is closed and the probe logic detection is not initiated; when a user takes hot water (i.e., a hot water take command is received), it is determined whether the first maximum water level value ΔA and the second maximum water level value ΔB are within the range of Δmin to Δmax. If the first maximum water level value ΔA is not within the range, the abnormal flag bit Aflg at the first probe A1 and the second probe A2 is set to 1, and a water shortage warning is displayed; otherwise, the abnormal flag bit Aflg at the first probe A1 and the second probe A2 is cleared (i.e., the abnormal flag bit Aflg at the first probe A1 and the second probe A2 is set to 0).

[0144] If the second maximum water level value ΔB is not within the range of Δmin to Δmax, the abnormal flag bit Bflg at the third probe B1 and the fourth probe B2 is set to 1, and a water shortage warning is displayed at the same time; otherwise, the abnormal flag bit Bflg at the third probe B1 and the fourth probe B2 is cleared (i.e., the abnormal flag bit Bflg at the third probe B1 and the fourth probe B2 is set to 0).

[0145] Determine whether the abnormal flag bit Aflg at the first probe A1 and the second probe A2 is 0 and whether the abnormal flag bit Bflg at the third probe B1 and the fourth probe B2 is 0. If yes, it means that the water supply in the pipeline is normal, the heating is turned on normally, and the hot water required by the user is produced. If no, it means that the water supply in the pipeline is abnormal, the heating is not turned on, and room temperature water is produced.

[0146] This embodiment ensures that the heating element will not dry-burn under abnormal conditions in the pipeline and provides the user with room temperature water. At the same time, the alarm mechanism can also notify the user of machine malfunctions that require maintenance, ensuring the user's subsequent experience. In addition, this embodiment adopts a design with at least two probes, providing double protection and preventing the risk of single failure, making it more reliable, stable, and low-cost.

[0147] This embodiment uses at least two probes at the front end of the heating element to detect the water level in the water purifier's pipeline. Specifically, the maximum water level value is obtained from at least two water level values ​​detected by the probes. If the maximum water level value is determined to be outside the range of the minimum and maximum preset water level values, an abnormal water supply to the water purifier's pipeline is identified. The abnormality flags at both probes are set to 1, a water shortage warning message is output, and the heating element is shut down. This method, based on at least two probes, enables water shortage detection, preventing the failure of any single probe from affecting the detection and mitigating the risk of the heating element burning out. Furthermore, the use of probes is cost-effective, reliable, and stable.
