Heat exchange tube: the dishwasher is provided with a pipeline structure for transferring the residual heat of the main washing hot water to be discarded after use to tap water newly entering the dishwasher. The temperature of the inlet water of the tap water is raised through the heat exchange pipe.
Main washing water: the main water used for the washing action of the dish washing machine is pumped by a water pump, and the main washing water in a main washing water tank is sprayed on the tableware to clean the residues and pollutants on the surface of the tableware. The contaminants fall into the main wash tank again with the main wash water, thereby repeating the washing.
In the related art, the main measure for preventing the heat exchange tube from leaking is to check the heat exchange tube before the dish washer leaves the factory, but no means is used for monitoring whether the heat exchange tube leaks or not along with the increase of the service life after the dish washer is put into use.
In order to solve the technical problems mentioned in the background, according to an aspect of embodiments of the present application, an embodiment of a leak detection method is provided.
Alternatively, in the embodiment of the present application, the method described above may be applied to a hardware environment formed by the terminal 101 and the server 103 as shown in fig. 1. As shown in fig. 1, a server 103 is connected to a terminal 101 through a network, which may be used to provide services for the terminal or a client installed on the terminal, and a database 105 may be provided on the server or separately from the server, and is used to provide data storage services for the server 103, and the network includes but is not limited to: wide area network, metropolitan area network, or local area network, the terminal 101 includes but is not limited to a dishwasher, a PC intelligently connected to a dishwasher, a cell phone, a tablet computer, etc.
A leak detection method in this embodiment may be executed by the server 103, may be executed by the terminal 101 alone, or may also be executed by both the server 103 and the terminal 101, as shown in fig. 2, where the method may include the following steps:
step S202, first detection data and second detection data are obtained, the first detection data are obtained by detecting a first fluid at a first end of a pipeline to be detected, the second detection data are obtained by detecting the first fluid at a second end of the pipeline to be detected, the first fluid flows into the pipeline to be detected through the first end, after heat exchange is generated between the first fluid and a second fluid outside the pipeline to be detected in the pipeline to be detected, the second fluid flows out of the pipeline to be detected through the second end, and the second fluid is in contact with the outer wall of the pipeline to be detected.
The embodiment of the present application will be specifically described with respect to the application of the leak detection method to a dishwasher. The first fluid can be clean tap water, the second fluid can be high-temperature main washing water after tableware is washed, the pipeline to be detected can be a heat exchange pipe in the dish washing machine, and the heat exchange pipe is a pipeline structure which is used for transferring residual heat of the main washing hot water which needs to be discarded after being used to tap water newly entering the dish washing machine in the dish washing machine. The temperature of the inlet water of the tap water can be raised through the heat exchange pipe. First and second sensed data of clean tap water (i.e., the first fluid) may be acquired from the heat exchange tube by the sensor device. The first detection data and the second detection data may be electrical signals, the strength of the electrical signals may indicate the concentration of ions, impurities, and the like in the first fluid, and the strength of the electrical signals may be changed due to the difference between the concentration of the heat exchange tubes inside and outside the heat exchange tubes. The inside of the heat exchange tube is clean tap water with low ion and impurity concentrations, and the outside of the heat exchange tube is main washing water and dirty water with high ion and impurity concentrations.
In the embodiment of the application, after entering the heat exchange tube from the water inlet, tap water exchanges heat with high-temperature main washing water outside the heat exchange tube when flowing through the inner pipeline of the bent long path of the heat exchange tube, and the residual temperature of the high-temperature main washing water is absorbed. The alkaline detergent is added into the high-temperature main washing water, so that the high-temperature main washing water contains hydroxide ions with higher concentration than tap water, when the clean tap water in the heat exchange tube exchanges heat with external high-temperature main washing water, if the heat exchange tube leaks due to leakage points and other conditions, the external high-temperature main washing water leaks into the clean tap water, so that the clean tap water is polluted, and the hydroxide ion concentration value in the internal tap water is increased.
Optionally, in order to detect whether the heat exchange tube leaks, the ion concentration in the tap water before and after heat exchange can be obtained through a detection signal of the sensor, specifically, an ion concentration sensor is disposed at a water inlet of the heat exchange tube (i.e., at the first end of the pipeline to be detected), and the hydroxide ion concentration in the tap water is detected through an electrical signal detected by the ion concentration sensor, so that the first detection data can represent the first ion concentration, which represents the concentration value of the hydroxide ion contained in the tap water before flowing into the heat exchange tube. An ion concentration sensor can be arranged at a water outlet of the heat exchange tube (namely, the second end of the pipeline to be detected), and the hydroxide ion concentration in the tap water after heat exchange is detected through an electric signal detected by the ion concentration sensor, so that the second detection data can represent the second ion concentration and represent the concentration value of the hydroxide ions contained in the tap water after flowing out of the heat exchange tube.
Alternatively, other detection devices such as an ammeter and the like may be used in the embodiments of the present application to determine the change in ion concentration in the tap water before and after heat exchange by presetting the correspondence between the detection data and the ion concentration. The embodiment of the application can also judge whether the heat exchange tube leaks or not by detecting other change data in tap water before and after heat exchange, and the detection of the hydroxide ion concentration is only taken as a preferred embodiment for explanation.
And step S204, determining that the second fluid leaks into the pipeline to be detected under the condition that a detection result obtained by utilizing the first detection data and the second detection data meets a preset condition.

step 1, determining a concentration difference value according to a first ion concentration and a second ion concentration;
and 2, determining that the second fluid leaks into the pipeline to be detected under the condition that the concentration difference value meets the preset condition.
Optionally, determining that the second fluid leaks into the to-be-detected pipeline when the concentration difference value meets the preset condition includes: comparing the concentration difference with a target threshold, wherein the target threshold is the maximum value of the self error of the detection device; and determining that the second fluid leaks into the pipeline to be detected under the condition that the concentration difference value is larger than the target threshold value.
In the embodiment of the application, can confirm whether great change takes place for the hydroxyl ion concentration in the running water after carrying out the heat exchange according to first ion concentration and second ion concentration, ion concentration sensor self has the error of certain limit, consequently change around the hydroxyl ion concentration in error range, can confirm that the outside high temperature main wash water of hot exchange pipe does not leak to the inside clean running water of hot exchange pipe internal contamination, and change around the hydroxyl ion concentration and exceed error range, then can confirm that the outside high temperature main wash water of hot exchange pipe leaks to hot exchange inside the pipe, thereby polluted clean running water. The preset condition may be an ion concentration difference threshold set according to actual conditions, or may be an error range of the ion concentration sensor itself.
By adopting the technical scheme, whether the heat exchange tube leaks or not can be determined by detecting the change of the concentration of hydroxide ions contained in the tap water and the high-temperature main washing water before and after heat exchange, the technical problem that whether the heat exchange tube leaks or not is monitored in the using process after a commercial dish washing machine is put into use is solved, and the quality of washing tableware of the dish washing machine is ensured.
The embodiment of the application further provides a method for more accurately detecting whether the heat exchange tube leaks, and particularly, on the basis that the difference of the hydroxide ion concentration detected by the embodiment is larger than the error range, the detection is continued, and when the condition of the duration is also met, the heat exchange tube is determined to leak. The following is a detailed description of the steps in the above examples.
Optionally, in the case that the concentration difference is greater than the target threshold, the method further comprises continuously detecting as follows:
step 1, acquiring a concentration difference value at preset time intervals;
step 2, comparing the concentration difference value obtained each time with a target threshold value;
and 3, determining that the second fluid leaks into the pipeline to be detected under the condition that the concentration difference value is larger than the target threshold value and the duration time is larger than the target time.
In the embodiment of the present application, when it is detected that the hydroxide ion concentration in the tap water before and after heat exchange is greater than the maximum value of the error of the ion concentration sensor itself, the duration of occurrence of the situation is continuously detected, and if the duration is greater than the target time, it can be determined that the main wash water leaks into the heat exchange pipe. And whether the detection results of two adjacent times are consistent or not can be judged, if the concentration difference value exceeds the error range in the previous time and the detection result of the later time is in the normal range, the detection result may still be false detected or the dishwasher is restarted and high-temperature main washing water after use does not exist, so that the condition that the ion concentration difference value exceeds the error range continuously can be judged to be leaked more accurately. The preset time interval may be 5 seconds, or may be other settings, and the target time may be 1 minute, or may be set according to actual needs.
The embodiment of the application also provides a subsequent treatment method for determining leakage of the heat exchange tube.
Optionally, after determining that the second fluid leaks into the interior of the pipeline to be tested, the method further comprises: generating a valve closing signal; sending a valve closing signal to the electromagnetic valve to drive the electromagnetic valve to close the valve; and/or, generating a leak cue signal; and sending the leakage prompt signal to an alarm device so as to drive the alarm device to send a leakage prompt to the target object.
In the embodiment of the application, once the heat exchange pipe is determined to leak, the electromagnetic valve can be controlled to close the valve so as to stop subsequent tableware cleaning work, and meanwhile, the alarm device can be controlled to give out a prompt, for example, the alarm bell is controlled to give out a ring, and after-sales personnel can be informed to go to the door for inspection and maintenance in the modes of mails, short messages and the like.
The method comprises the steps of obtaining first detection data and second detection data, wherein the first detection data are obtained by detecting a first fluid at a first end of a pipeline to be detected, the second detection data are obtained by detecting the first fluid at a second end of the pipeline to be detected, the first fluid flows into the pipeline to be detected through the first end, after heat exchange is generated between the first fluid and a second fluid outside the pipeline to be detected in the pipeline to be detected, the second fluid flows out of the pipeline to be detected through the second end, and the second fluid is in contact with the outer wall of the pipeline to be detected; under the condition that the detection result obtained by utilizing the first detection data and the second detection data meets the preset condition, the second fluid is determined to leak to the interior of the pipeline to be detected, the technical problem that whether the heat exchange tube leaks or not is continuously monitored in the using process after the commercial dish washing machine is put into use is solved, the quality of the dish washing machine for washing tableware is ensured, and the operation risk caused by the leakage of the heat exchange tube is reduced.
