Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as specifically described herein and, therefore, the scope of the present invention is not limited by the specific embodiments disclosed below.
The instant heating device, the working state diagnosis method and device thereof, and the water treatment device provided by the embodiments of the present application will be described in detail with reference to fig. 1 to 16 through specific embodiments and application scenarios thereof.
First embodiment, fig. 1 shows one of the flow diagrams of the method for diagnosing the operating state of the instant heating apparatus according to the embodiment of the present invention. The working state diagnosis method comprises the following steps:
step S102, acquiring water temperature data, namely a first operation state of a heat pipe and a second operation state of a water pump;
and step S104, performing combined analysis on the first operation state, the second operation state and the water temperature data so as to diagnose the working state of the instant heating device.
The working state diagnosis method of the instant heating device provided by the embodiment is used for the instant heating device, and the instant heating device is provided with an instant heating pipe, a water pump, a water inlet and outlet pipeline and other components. In the actual application process of the instant heating device, the problem of the water supply end of the instant heating device usually occurs due to the reason that the water inlet and outlet pipelines are connected in a wrong way, namely, the faults of parts such as a heat pipe or a water pump and the like, so that the instant heating device is in an abnormal working state with no water or little water. At this moment, if the instant heating device continues to work, the parts or the internal pipelines of the instant heating device can be damaged, even the safety accident problem can occur, and the operation reliability and the safety of the instant heating device are reduced.
Therefore, in the working state diagnosis method of the instant heating device provided by the embodiment, the first working state of the instant heating device and the second working state of the water pump are acquired, the plurality of water temperature data in the instant heating device are acquired according to the plurality of temperature sensors installed inside the instant heating device, and then the current working state of the entire instant heating device is diagnosed by performing joint analysis on the plurality of acquired water temperature data, the first working state and the second working state, so that the working state of the entire instant heating device is determined to be normal or abnormal. Therefore, the operating state of the instant heating device, the operating state of the water pump and the water temperature data are jointly analyzed, the complete machine state of the instant heating device is quickly and accurately judged, corresponding treatment measures are taken in time when the instant heating device is in an abnormal operating state, the situation that the internal parts or pipelines of the instant heating device are damaged due to the fact that the instant heating device continues to work in the abnormal operating state is avoided, and the operation reliability and safety of the instant heating device are improved.
The first operation state is expressed as the working state of the heat pipe, and the first operation state comprises a heating state and a non-heating state which respectively correspond to a heating working mode and a non-heating working mode of the heat pipe. The second operation state represents the operation state of the water pump, and the second operation state comprises two conditions of an operation state and a non-operation state, which respectively correspond to two operation modes of the water pump, namely operation and stop.
Further, the water temperature data includes temperature data such as the water inlet temperature and the water outlet temperature of the heat pipe. It can be understood that, during the operation of the instant heating device, the operation states of the components (such as the water pump and the heat pipe) of the instant heating device affect the water temperature data in the instant heating device, and the water temperature data in the instant heating device is different according to the operation states of the components of the instant heating device, or there is a certain relationship between the water temperature data of the instant heating device and the operation states of the components of the instant heating device. Therefore, the operation state of the instant heating device can be quickly and accurately diagnosed by jointly analyzing a plurality of data such as the operation state of the instant heating pipe, the operation state of the water pump, the water temperature data and the like in the instant heating device and further combining the corresponding relation among the data in the normal operation state, and the operation reliability and the operation safety of the instant heating device are improved.
In addition, the water temperature data should be acquired later than the first operation state and the second operation state of the water pump. Specifically, after the first operation state of the instant heating pipe and the second preset state of the water pump are acquired for the preset time, the water temperature data of the instant heating device are acquired. Namely, the water temperature data in the heating device is influenced by the operation states of the components of the heating device (such as the water pump and the heat pipe), or there is a certain correlation between the water temperature data of the heating device and the operation states of the components of the heating device. Therefore, the water temperature data is acquired after the first operation state and the second operation state are acquired for the preset time, the current acquired water temperature data can be guaranteed to be the water temperature data influenced by the first operation state and the second operation state, namely, the current acquired water temperature data is guaranteed to have an incidence relation with the first operation state and the second operation state, and on the basis, the first operation state expressing the working state of the instant heat pipe, the second operation state expressing the working state of the water pump and the plurality of water temperature data in the instant heat device can be subjected to combined analysis, so that the whole working state of the instant heat device can be rapidly and accurately diagnosed according to an analysis result.
Wherein, in order to prevent the instant heating device from damaging the parts of the instant heating device or the internal pipeline when the instant heating device works for a long time under the abnormal working state, the preset time is not suitable to be too long. Specifically, the preset time may be shorter than 3 seconds, 4 seconds, 5 seconds, and the like, due to the fast-acting working performance of the instant heating device, and is not particularly limited herein.
In summary, the working state diagnostic method for the instant heating device provided in the embodiment of the present invention performs joint analysis on multiple data of the operation state of the instant heating pipe, the operation state of the water pump, the water temperature data, and the like in the instant heating device, and rapidly and accurately diagnoses the whole working state of the instant heating device through the correlation relationship among the data, so as to take corresponding processing measures in time when the instant heating device is abnormal in operation, avoid damage to internal parts or pipelines of the instant heating device due to continuous operation of the instant heating device in an abnormal working state, and improve the reliability and safety of the operation of the instant heating device.

step S202, acquiring water temperature data, namely a first operation state of the heat pipe and a second operation state of the water pump;
step S204, judging whether the current state is a first operation state which is a heating state, and a second operation state which is an operation state, if so, executing step S206, and if not, ending the process;
step S206, determining that the working state of the instant heating device is normal under the condition that the outlet water temperature of the instant heating device is higher than the inlet water temperature and the heating temperature of the heat pipe is also higher than the inlet water temperature;
step S208, under the condition that the water outlet temperature is less than or equal to the water inlet temperature or the heating temperature of the heat pipe is less than or equal to the water inlet temperature, the working state of the instant heating device is determined to be abnormal.
In the embodiment, under the condition that the instant heating pipe is in the heating state and the water pump is in the running state, the whole working state of the instant heating device is diagnosed according to the comparison result between the water inlet temperature and the water outlet temperature of the instant heating device and the comparison result between the water inlet temperature and the heating temperature of the instant heating pipe. Specifically, under the condition that the outlet water temperature of the instant heating device is greater than the inlet water temperature and the heating temperature of the heat pipe is also greater than the inlet water temperature, it is determined that the instant heating device is currently in the normal working state of the whole machine, and under the condition that the outlet water temperature is less than or equal to the inlet water temperature or the heating temperature of the heat pipe is less than or equal to the inlet water temperature, it is determined that the instant heating device is currently in the abnormal working state of the whole machine. Therefore, under the condition that the instant heating pipe is in a heating state and the water pump is in a running state, the working state of the whole instant heating device is quickly and accurately diagnosed directly according to the comparison result of the water inlet temperature and the water outlet temperature of the instant heating device and the comparison result of the water inlet temperature and the heating temperature of the instant heating pipe, and the running reliability and the running safety of the instant heating device are improved.
Specifically, in this embodiment, when it is determined that the instant heating device is in the complete machine abnormal operation state, the specific abnormal condition of the instant heating device can be diagnosed and processed from four aspects of the reverse installation of the water inlet and outlet pipeline, namely, the damage or wrong connection of the heat pipe, the damage of the water pump, and the damage or wrong connection of the temperature sensor.
In addition, in the embodiment, after the instant heating device is determined to be in the abnormal working state of the whole machine, the instant heating device can be controlled to automatically enter the abnormal processing program. Specifically, modes such as accessible control instant heating device stops out water, control instant heating pipe stop heating of instant heating device, control instant heating device's water pump stall avoid instant heating device to continue to work under unusual operating condition to avoid causing the damage to spare part or internal pipeline in the instant heating device, promoted the reliability and the security of instant heating device operation, guaranteed instant heating device's life.
In a third embodiment, fig. 3 shows a third flowchart of the method for diagnosing the operating state of the instant heating device according to the third embodiment of the present invention. The working state diagnosis method comprises the following steps:
step S302, acquiring water temperature data, namely a first operation state of a heat pipe and a second operation state of a water pump;
step S304, judging whether the current state is a first operation state which is a heating state and a second operation state which is a non-operation state, if so, executing step S306, and if not, ending the process;
step S306, determining that the working state of the instant heating device is normal under the condition that the heating temperature of the instant heating pipe is greater than the water inlet temperature;
step S308, under the condition that the heating temperature of the instant heating pipe is less than or equal to the water inlet temperature, the working state of the instant heating device is determined to be abnormal.
In the embodiment, under the condition that the instant heating pipe is in the heating state and the water pump is in the non-operation state, the diagnosis of the working state of the instant heating device complete machine is completed directly according to the comparison result of the water inlet temperature of the instant heating device and the heating temperature of the instant heating device, so as to judge that the instant heating device complete machine is in the abnormal state or the normal state. Specifically, when the temperature of the instant pipe is greater than the water inlet temperature, the current working state of the instant device is determined to be a complete machine normal state, and when the temperature of the instant pipe is less than or equal to the water inlet temperature, the current working state of the instant device is determined to be a complete machine abnormal state. Therefore, under the condition that the working state of the instant heating pipe is the heating state and the working state of the water pump is the non-running state, the whole working state of the instant heating device is rapidly and accurately diagnosed directly according to the obtained comparison result between the inlet water temperature and the heating temperature of the instant heating pipe, and the running reliability and safety of the instant heating device are improved.
Specifically, in this embodiment, when it is determined that the instant heating device is in the complete machine abnormal operation state, the specific abnormal condition of the instant heating device can be diagnosed and processed from two aspects, namely, the damage or the error connection of the instant heating pipe and the damage or the error connection of the temperature sensor.
In addition, in the embodiment, after the instant heating device is determined to be in the abnormal working state of the whole machine, the instant heating device can be controlled to automatically enter the abnormal processing program. Specifically, the instant heating device can be controlled to stop water outlet, and the instant heating pipe of the instant heating device is controlled to stop heating, so that the instant heating device is prevented from continuously working in an abnormal working state, the damage to parts or internal pipelines in the instant heating device is avoided, the running reliability and safety of the instant heating device are improved, and the service life of the instant heating device is ensured.
In a fourth embodiment, fig. 4 is a fourth flowchart illustrating a method for diagnosing an operating state of an instant heating apparatus according to an embodiment of the present invention. The working state diagnosis method comprises the following steps:
step S402, acquiring water temperature data, namely a first operation state of the heat pipe and a second operation state of the water pump;
step S404, judging whether the first running state is a non-heating state, if so, executing step S406, and if not, ending the flow;
step S406, obtaining a first difference value according to the difference value between the first water outlet temperature and the first water inlet temperature at the first moment;
step S408, obtaining a second difference value according to the difference value between the second water outlet temperature and the second water inlet temperature at the second moment;
step S410, determining the actual temperature rise change rate according to the first difference value, the second difference value and the time interval between the first moment and the second moment;
step S412, diagnosing the operating state of the instant heating device according to the comparison result of the actual temperature rise change rate and the preset temperature rise change rate.
In this embodiment, under the condition that the instant heating pipe is in the non-heating state, the current actual temperature rise change rate of the instant heating device is calculated without considering the working state of the water pump, and then the current complete machine working state of the instant heating device is diagnosed according to the comparison result of the actual temperature rise change rate and the preset temperature rise change rate. Specifically, a first outlet water temperature and a first inlet water temperature of the instant heating device at a first time are obtained, a difference value between the first outlet water temperature and the first inlet water temperature is calculated to obtain a first difference value (namely, a first temperature rise), a second outlet water temperature and a second inlet water temperature of the instant heating device at a second time are further obtained, a difference value between the outlet water temperature and the inlet water temperature of the instant heating device at the time is calculated to obtain a second difference value (namely, a second temperature rise), on the basis, a temperature rise change value of the instant heating device in a time period from the first time to the second time is determined according to the obtained first difference value and the obtained second difference value, an actual temperature rise change rate of the instant heating device in the time period from the first time to the second time is further determined by combining a time interval between the first time and the second time, and then a comparison result of the obtained actual temperature rise change rate to a preset temperature rise change rate is used for diagnosing the working state of the instant heating device. Therefore, under the condition that the instant heating device is determined to be in the non-heating state, the operation state of the water pump does not need to be considered, the actual temperature rise change rate of the instant heating device is directly obtained, and the working state of the whole instant heating device is rapidly and accurately diagnosed according to the comparison result of the actual temperature rise change rate and the preset temperature rise change rate, so that the operation reliability and the operation safety of the instant heating device are improved.
The preset temperature rise change rate is related to the current working power of the instant heating device and the water outlet flow rate. Specifically, when the instant heating device is in a normal heating water outlet state, the normal change speed of the temperature rise of the instant heating device (i.e., the difference between the water outlet temperature and the water inlet temperature of the instant heating device) under different power and different flow rate working condition combinations is obtained, the normal change speed is determined as the standard temperature rise change rate under the current power and flow rate combination, and then the preset temperature rise change rate of the instant heating device when the instant heating device is in a non-heating state is obtained by weighting or superposing one temperature value on the standard temperature rise change rate.
In addition, in the actual application process, as shown in table 1, the preset temperature rise change rates of the instant heating device under different power and flow rate working condition combinations can be obtained according to the above manner, and the matching relationship between the preset temperature rise change rates and the working condition combinations is established, so that the preset temperature rise change rates under all the working conditions are prestored in the memory of the instant heating device in the form of a table or a document. Therefore, under the condition that the instant heating pipe of the instant heating device is determined to be in a non-heating state, the preset temperature rise change rate matched with the current power and the current speed can be searched from the prestored table or document according to the current working power and the current speed of the instant heating device, and the complete machine working state of the instant heating device is diagnosed according to the comparison result of the actual temperature rise change rate and the preset temperature rise change rate.

Fifth embodiment, fig. 5 shows a fifth flowchart of the method for diagnosing the operating state of the instant heating apparatus according to the embodiment of the present invention. The working state diagnosis method comprises the following steps:
step S502, acquiring water temperature data, namely a first operation state of the heat pipe and a second operation state of the water pump;

step S508, obtaining a second difference value according to the difference value between the second water outlet temperature and the second water inlet temperature at the second moment;
step S510, determining the actual temperature rise change rate according to the first difference value, the second difference value and the time interval between the first moment and the second moment;
step S512, under the condition that the preset temperature rise change rate is greater than or equal to the actual temperature rise change rate, judging that the working state of the instant heating device is normal;
and step S514, judging that the working state of the instant heating device is abnormal under the condition that the preset temperature rise change rate is smaller than the actual temperature rise change rate.
In this embodiment, when the instant heating pipe is in the non-heating state, the operating state of the instant heating device is diagnosed according to the comparison result between the actual temperature rise change rate and the preset temperature rise change rate, specifically, when the preset temperature rise change rate is greater than or equal to the actual temperature rise change rate, the operating state of the instant heating device is determined to be normal, and when the preset temperature rise change rate is smaller than the actual temperature rise change rate, the operating state of the instant heating device is determined to be abnormal. Therefore, under the condition that the instant heating device is determined to be in the non-heating state, the running state of the water pump does not need to be considered, the actual temperature rise change rate of the instant heating device is directly obtained according to the change condition of the temperature rise of the instant heating device along with the time, the working state of the whole instant heating device is quickly and accurately diagnosed according to the comparison result between the actual temperature rise change rate and the preset temperature rise change rate, and the running reliability and safety of the instant heating device are improved.
The preset temperature rise change rate is related to the current power of the instant heating device and the water outlet flow rate. In an actual application process, as shown in table 1 above, the preset temperature rise change rates of the instant heating device under different power and flow rate working condition combinations can be obtained, the matching relationship between the preset temperature rise change rates and the working condition combinations is established, and the preset temperature rise change rates under all the working conditions are prestored in the memory of the instant heating device in a form of a table or a document so as to be directly taken and used subsequently.
Illustratively, the instant heating pipe of the instant heating device is in a non-heating state, that is, the current power of the instant heating device is 1200W, the flow rate is 400ml/s, and the preset temperature rise change rate under the current working condition combination is found to be 11 ℃/s through table 1. At this time, if the current outlet water temperature of the instant heating device is detected to be 55 ℃ and the inlet water temperature is 33 ℃, and after 2 seconds, the outlet water temperature of the instant heating device is detected to be 99 ℃ and the inlet water temperature is 33 ℃, the current actual temperature rise change rate of the instant heating device is 22 ℃/s and 22 ℃/s is more than 11 ℃/s through calculation, namely the preset temperature rise change rate is smaller than the current actual temperature rise change rate, and the working state of the whole instant heating device is judged to be abnormal.
In addition, in the embodiment, after the instant heating device is determined to be in the abnormal working state of the whole machine, the instant heating device can be controlled to automatically enter the abnormal processing program. Specifically, the mode that the accessible control is heat device stops out water or the water pump of control heat device stops to operate promptly avoids heat device to continue to work under unusual operating condition promptly to avoid causing the damage to spare part or internal pipeline in the heat device promptly, promoted the reliability and the security of heat device operation promptly, guaranteed the life of heat device promptly.

Ninth embodiment, fig. 9 shows a schematic block diagram of an operating state diagnosing apparatus 900 of an instant heating apparatus according to an embodiment of the present invention. Wherein, this operating condition diagnostic device includes:
an obtaining module 902, configured to obtain water temperature data, that is, a first operating state of the heat pipe and a second operating state of the water pump;
and a processing module 904 for diagnosing the operating state of the instant heating device according to the first operating state, the second operating state and the water temperature data.
The working condition diagnosing apparatus 900 of the instant heating apparatus is used for the instant heating apparatus, and the instant heating apparatus is provided with a heat pipe, a water pump, a water inlet and outlet pipeline, and the like. In the actual application process of the instant heating device, the problem of the water supply end of the instant heating device usually occurs due to the reason that the water inlet and outlet pipelines are connected in a wrong way, namely, the faults of parts such as a heat pipe or a water pump and the like, so that the instant heating device is in an abnormal working state with no water or little water. At this moment, if the instant heating device continues to work, the parts or the internal pipelines of the instant heating device can be damaged, even the safety accident problem can occur, and the operation reliability and the safety of the instant heating device are reduced.
Therefore, in the operating state diagnosing apparatus 900 of the instant heating apparatus proposed in this embodiment, the acquiring module 902 is used to acquire the first operating state of the instant heating pipe, the second operating state of the water pump, and the water temperature data in the instant heating apparatus, and then the processing module 904 is used to perform a joint analysis on the acquired first operating state, second operating state, and water temperature data, so as to diagnose the current overall operating state of the instant heating apparatus, and determine that the overall operating state of the instant heating apparatus is normal or abnormal. Therefore, the operating state of the instant heating device, the operating state of the water pump and the water temperature data are jointly analyzed by the processing module 904, so that the complete machine state of the instant heating device can be quickly and accurately judged, corresponding processing measures can be taken in time when the instant heating device works abnormally, the instant heating device is prevented from continuously working under the abnormal working state to damage internal parts or pipelines of the instant heating device, and the reliability and the safety of the operation of the instant heating device are improved.
The first operation state is expressed as the working state of the heat pipe, and the first operation state comprises a heating state and a non-heating state which respectively correspond to a heating working mode and a non-heating working mode of the heat pipe. The second operation state represents the operation state of the water pump, and the second operation state comprises two conditions of an operation state and a non-operation state, which respectively correspond to two operation modes of the water pump, namely operation and stop.
Further, the water temperature data includes temperature data such as the water inlet temperature and the water outlet temperature of the heat pipe. It can be understood that, during the operation of the instant heating device, the operation states of the components (such as the water pump and the heat pipe) of the instant heating device affect the water temperature data in the instant heating device, and the water temperature data in the instant heating device is different according to the operation states of the components of the instant heating device, or there is a certain relationship between the water temperature data of the instant heating device and the operation states of the components of the instant heating device. Therefore, the operation state of the integral machine of the instant heating device can be quickly and accurately diagnosed by jointly analyzing a plurality of data such as the operation state of the instant heating pipe, the operation state of the water pump, the water temperature data and the like in the instant heating device and further combining the corresponding relation among the data in the normal operation state, and the operation reliability and the operation safety of the instant heating device are improved.
