Technical Field

[0002] The present invention relates to the technical field of instant heating, and in particular to an instant heating device, a method and device for diagnosing its working status, and a water treatment device. Background Art

[0003] During the actual use of instant heating devices, problems with the water supply often occur due to incorrect connections in the inlet and outlet pipes, component failures, etc., resulting in insufficient water supply, which causes the device to operate abnormally with no or insufficient water. If the instant heating device continues to operate in this abnormal state, it will usually cause damage to the components or internal pipes of the device, and may even cause safety accidents, posing a threat to the user's personal safety and reducing the reliability and safety of the device. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, a first aspect of the present invention is to provide a method for diagnosing the working status of an instant heating device.

[0006] A second aspect of the present invention is to provide a device for diagnosing the working status of an instant heating device.

[0007] The third aspect of the present invention is to provide an instant heating device.

[0008] A fourth aspect of the present invention is to provide an instant heating device.

[0009] A fifth aspect of the present invention is to provide a water treatment device.

[0010] A sixth aspect of the present invention is to provide a readable storage medium.

[0011] In view of this, according to one aspect of the present invention, a method for diagnosing the working status of an instant heating device is proposed. The instant heating device includes a water pump and an instant heating pipe. The working status diagnosis method includes: obtaining a first operating status of the instant heating pipe and a second operating status of the water pump; obtaining water temperature data; and diagnosing the working status of the instant heating device based on the first operating status, the second operating status, and the water temperature data.

[0012] The present invention proposes a method for diagnosing the operating status of an instant heating device, which is used in an instant heating device equipped with components such as an instant heating pipe, a water pump, and inlet and outlet pipes. In actual use, problems with the water supply of the instant heating device can often occur due to incorrect connections in the inlet and outlet pipes, or failure of components such as the instant heating pipe or water pump, causing the device to operate abnormally with or without water. Continuing to operate in this situation can damage the components or internal pipes, and may even lead to safety issues, reducing the reliability and safety of the device.

[0013] Therefore, in the method for diagnosing the working state of an instant heating device proposed in the present invention, 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 device are obtained, and then the obtained first operating state, second operating state, and water temperature data are jointly analyzed to diagnose the current working state of the entire instant heating device and determine whether the working state of the entire instant heating device is normal or abnormal. In this way, by jointly analyzing the operating state of the instant heating pipe, the operating state of the water pump, and the water temperature data in the instant heating device, a rapid and accurate judgment of the entire state of the instant heating device is achieved, so that corresponding treatment measures can be taken in a timely manner when the working state of the instant heating device is abnormal, avoiding damage to the internal parts or pipelines of the instant heating device caused by the instant heating device continuing to operate in an abnormal working state, thereby improving the reliability and safety of the operation of the instant heating device.

[0014] The method for diagnosing the working status of the instant heating device according to the present invention may also have the following additional technical features:

[0015] In the above technical solution, based on the first operating state being the heating state and the second operating state being the operating state, the water temperature data includes the inlet water temperature and the outlet water temperature, the working state of the instant heating device is diagnosed according to the first operating state, the second operating state and the water temperature data, including: based on the inlet water temperature being lower than the outlet water temperature, and the inlet water temperature being lower than the heating temperature of the instant heating pipe, determining that the working state of the instant heating device is normal; based on the inlet water temperature being greater than or equal to the outlet water temperature, or the inlet water temperature being greater than or equal to the heating temperature, determining that the working state of the instant heating device is abnormal.

[0016] In this technical solution, a first operating state of a heat pipe in an instant heating device, a second operating state of a water pump, and water temperature data in the instant heating device are obtained. When the heat pipe is in a heating state and the water pump is in an operating state, the operating state of the entire instant heating device is diagnosed based on the comparison results of the water inlet and outlet temperatures of the instant heating device, as well as the comparison results of the water inlet temperature and the heating temperature of the heat pipe. Specifically, if the water outlet temperature of the instant heating device is greater than the water inlet temperature and the heating temperature of the heat pipe is also greater than the water inlet temperature, the instant heating device is determined to be in a normal operating state. If 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 instant heating device is determined to be in an abnormal operating state. In this way, when the heat pipe is in a heating state and the water pump is in an operating state, the operating state of the entire instant heating device can be quickly and accurately diagnosed based on the comparison results of the water inlet and outlet temperatures of the instant heating device, as well as the comparison results of the water inlet temperature and the heating temperature of the heat pipe, thereby improving the reliability and safety of the operation of the instant heating device.

[0017] Specifically, in this technical solution, when it is determined that the instant heating device is in an abnormal working state, the specific abnormal condition of the instant heating device can be diagnosed and handled from four aspects: the inlet and outlet water pipes are installed upside down, the instant heating pipes are damaged or connected incorrectly, the water pump is damaged, and the temperature sensor is damaged or connected incorrectly.

[0018] In any of the above technical solutions, based on the first operating state being the heating state and the second operating state being the non-operating state, the water temperature data includes the inlet water temperature, and the working state of the instant heating device is diagnosed based on the first operating state, the second operating state, and the water temperature data, including: based on the inlet water temperature being less than the heating temperature of the instant heating pipe, determining that the working state of the instant heating device is normal; based on the inlet water temperature being greater than or equal to the heating temperature, determining that the working state of the instant heating device is abnormal.

[0019] In this technical solution, the first operating state of the instant heating pipe in the instant heating device, the second operating state of the water pump, and the water temperature data in the instant heating device are obtained. When the instant heating pipe is in a heating state and the water pump is in a non-operating state, the overall operating state of the instant heating device is diagnosed directly based on the comparison result between the water inlet temperature of the instant heating device and the heating temperature of the instant heating pipe. Specifically, when the heating temperature of the instant heating pipe is greater than the water inlet temperature, it is determined that the instant heating device is currently in a normal operating state of the entire device, and when the heating temperature of the instant heating pipe is less than or equal to the water inlet temperature, it is determined that the instant heating device is currently in an abnormal operating state of the entire device. In this way, when the instant heating pipe is in a heating state and the water pump is in a non-operating state, the overall operating state of the instant heating device is quickly and accurately diagnosed directly based on the comparison result between the water inlet temperature of the instant heating device and the heating temperature of the instant heating pipe, thereby improving the reliability and safety of the operation of the instant heating device.

[0020] In any of the above technical solutions, based on the first operating state being a non-heating state, the water temperature data includes the outlet water temperature, and the working state of the instant heating device is diagnosed according to the first operating state, the second operating state, and the water temperature data, including: obtaining a first difference between the first outlet water temperature and the first inlet water temperature at a first moment; obtaining a second difference between the second outlet water temperature and the second inlet water temperature at a second moment; determining the actual temperature rise rate of change according to the first difference, the second difference, and the time interval between the first moment and the second moment; and diagnosing the working state of the instant heating device according to a comparison result of the actual temperature rise rate of change and the preset temperature rise rate of change.

[0021] In this technical solution, the first operating state of the instant heating pipe in the instant heating device, the second operating state of the water pump and the water temperature data in the instant heating device are obtained. When the instant heating pipe is in a non-heating state (there is no need to consider the operating state of the water pump at this time), the actual temperature rise rate of the instant heating device is determined, and then the working state of the entire instant heating device is diagnosed based on the comparison result between the actual temperature rise rate and the preset temperature rise rate.

[0022] Specifically, when it is determined that the heating pipe is in a non-heating state, a first outlet water temperature and a first inlet water temperature of the heating device at a first moment are obtained, a first difference between the two (i.e., a first temperature rise) is calculated, and then a second outlet water temperature and a second inlet water temperature of the heating device at a second moment are obtained, and the difference between the outlet water temperature and the inlet water temperature of the heating device at this time is calculated to obtain a second difference (i.e., a second temperature rise). On this basis, based on the obtained first difference, second difference, and the time interval between the first moment and the second moment, the actual temperature rise change rate of the heating device during the time period from the first moment to the second moment is determined, and then the operating state of the heating device is diagnosed based on the comparison result between the obtained actual temperature rise change rate and the preset temperature rise change rate. In this way, when it is determined that the heating pipe is in a non-heating state, the actual temperature rise change rate of the heating device is directly obtained without considering the operating state of the water pump, and then the operating state of the heating device is quickly and accurately diagnosed based on the comparison result between the actual temperature rise change rate and the preset temperature rise change rate, thereby improving the reliability and safety of the operation of the heating device.

[0023] In any of the above technical solutions, the working state of the instant heating device is diagnosed based on the comparison result of the actual temperature rise change rate and the preset temperature rise change rate, including: determining that the working state of the instant heating device is normal based on the actual temperature rise change rate being less than or equal to the preset temperature rise change rate; determining that the working state of the instant heating device is abnormal based on the actual temperature rise change rate being greater than the preset temperature rise change rate.

[0024] In this technical solution, when diagnosing the operating status of the instantaneous heating device based on the comparison result between the actual temperature rise rate of change and the preset temperature rise rate of change, specifically, if the preset temperature rise rate of change is greater than the actual temperature rise rate of change, the operating status of the instantaneous heating device is determined to be normal, and if the preset temperature rise rate of change is less than or equal to the actual temperature rise rate of change, the operating status of the instantaneous heating device is determined to be abnormal. In this way, when it is determined that the instantaneous heating pipe is in a non-heating state, there is no need to consider the operating status of the water pump. The actual temperature rise rate of the instantaneous heating device is directly obtained based on the change in the temperature rise of the instantaneous heating device over time. Then, based on the comparison result between the actual temperature rise rate of change and the preset temperature rise rate of change, the operating status of the instantaneous heating device can be quickly and accurately diagnosed, thereby improving the reliability and safety of the operation of the instantaneous heating device.

[0025] In any of the above technical solutions, the preset temperature rise change rate is related to the power and water outlet flow rate of the instant heating device, and the working status diagnosis method also includes: according to the current power and current water outlet flow rate of the instant heating device, searching for the preset temperature rise change rate corresponding to the current power and current water outlet flow rate.

[0026] In this technical solution, the preset temperature rise rate of change is related to the current power and water outlet flow rate of the instant heating device. Specifically, when the instant heating device is in a normal heating and water outlet state, the normal rate of change of the temperature rise of the instant heating device (the difference between the outlet water temperature and the inlet water temperature of the instant heating device) under different power and flow rate operating conditions is obtained. This normal rate of change is determined as the standard temperature rise rate of change under the current power and flow rate combination. Then, by weighting the standard temperature rise rate of change or superimposing a temperature value, the preset temperature rise rate of change of the instant heating device is obtained for the current power and flow rate operating condition combination when the instant heating pipe is in a non-heating state.

[0027] In this technical solution, after obtaining the preset temperature rise change rates of the instant heating device under different power and flow rate operating condition combinations according to the above method, a matching relationship between the preset temperature rise change rates and the operating condition combinations can be established, and the preset temperature rise change rates under all operating conditions can be pre-stored in the memory of the instant heating device in the form of a table or document. In this way, if it is determined that the instant heating pipe of the instant heating device is in a non-heating state, the preset temperature rise change rate that matches the current power and water flow rate can be directly searched from the pre-stored table or document based on the current power and water flow rate of the instant heating device. The operating status of the entire instant heating device can then be diagnosed based on the comparison result between the actual temperature rise change rate and the preset temperature rise change rate.

[0028] In any of the above technical solutions, the working status diagnosis method further includes: after obtaining the first operating state of the heating pipe and the second operating state of the water pump, obtaining water temperature data at a preset time interval.

[0029] In this technical solution, the water temperature data is obtained later than the first operating state of the instant heating pipe and the second operating state of the water pump. Specifically, the water temperature data of the instant heating device is obtained after the first operating state of the instant heating pipe and the second preset state of the water pump are obtained for a preset time. The water temperature data in the instant heating device is affected by the operating state of each component of the instant heating device (such as the water pump and the instant heating pipe), or in other words, there is a certain correlation between the water temperature data of the instant heating device and the operating state of each component of the instant heating device. Therefore, by obtaining the water temperature data after the first operating state and the second operating state are obtained for a preset time, it can be ensured that the currently obtained water temperature data is the water temperature data after being affected by the first operating state and the second operating state, that is, it is ensured that the currently obtained water temperature data is associated with the first operating state and the second operating state. Based on this, 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 device can be jointly analyzed, so as to quickly and accurately diagnose the working state of the entire device according to the analysis results.

[0030] To prevent damage to the components or internal piping of the instant heating device caused by prolonged operation of the device under abnormal operating conditions, the preset time should not be too long. Specifically, due to the rapid operating performance of the instant heating device, the preset time can be a shorter time such as 3 seconds, 4 seconds, or 5 seconds, without specific limitation.

[0031] In any of the above technical solutions, after determining that the working state of the instant heating device is abnormal, the working state diagnosis method further includes: controlling the instant heating device to enter an abnormality handling program.

[0032] In this technical solution, upon determining that the instantaneous heating device is currently in an abnormal operating state, the device can be controlled to automatically enter an abnormality handling procedure. Specifically, the device can be controlled to stop discharging water, stopping heating of the heating pipes, or stopping the water pump to prevent the device from continuing to operate in an abnormal operating state. This prevents damage to the device's components or internal piping, improves the reliability and safety of the device's operation, and ensures its service life.

[0033] According to a second aspect of the present invention, a working status diagnostic device for an instant heating device is proposed. The instant heating device includes a water pump and an instant heating pipe. The working status diagnostic device includes: an acquisition module for acquiring water temperature data, a first operating state of the instant heating pipe and a second operating state of the water pump; and a processing module for diagnosing the working state of the instant heating device based on the first operating state, the second operating state and the water temperature data.

[0034] The present invention provides a device for diagnosing the operating status of an instant heating device, which is used in an instant heating device equipped with a heating pipe, a water pump, inlet and outlet pipes, and other components. In actual use, problems with the water supply of the instant heating device can often occur due to misconnections in the inlet and outlet pipes, or failure of components such as the heating pipe or water pump, causing the device to enter an abnormal operating state with no or insufficient water. Continuing to operate the instant heating device in this situation can damage its components or internal pipes, and may even lead to safety issues, reducing its operational reliability and safety.

[0035] Therefore, in the operating state diagnosis device for an instant heating device proposed in the present invention, an acquisition module 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 device. Furthermore, a processing module is used to jointly analyze the acquired first operating state, second operating state, and water temperature data to diagnose the current operating state of the entire instant heating device and determine whether the operating state of the entire instant heating device is normal or abnormal. In this way, the processing module's joint analysis of the operating state of the instant heating pipe, the operating state of the water pump, and the water temperature data in the instant heating device allows for a rapid and accurate judgment of the entire state of the instant heating device. This allows for timely implementation of appropriate treatment measures when the operating state of the instant heating device is abnormal, preventing the instant heating device from continuing to operate in an abnormal operating state and causing damage to internal parts or piping of the instant heating device, thereby improving the reliability and safety of the operation of the instant heating device.

[0036] According to a third aspect of the present invention, an instant heating device is provided, comprising a memory and a processor. The memory stores a program or instructions that, when executed by the processor, implement the steps of the method for diagnosing the operating status of an instant heating device as described in any of the aforementioned technical solutions. Therefore, this instant heating device possesses all the beneficial effects of the method for diagnosing the operating status of an instant heating device as described in any of the aforementioned technical solutions, and further description thereof is omitted.

[0037] According to a fourth aspect of the present invention, an instant heating device is proposed, comprising: a working status diagnostic device of the instant heating device in the above technical solution; an instant heat pipe electrically connected to the working status diagnostic device; and a water pump electrically connected to the working status diagnostic device.

[0038] The instant heating device provided in the fourth aspect of the present invention includes the working state diagnosis device of the instant heating device in the above technical solution. Therefore, the instant heating device has all the beneficial effects of the working state diagnosis device of the instant heating device in the above technical solution, which will not be repeated here.

[0039] Furthermore, the instant heating device also includes an instant heating pipe and a water pump, and the instant heating pipe and the water pump are electrically connected to the above-mentioned working status diagnostic device so that the working status diagnostic device can obtain the operating status of the water pump and the instant heating pipe, and then realize the diagnosis of the entire status of the instant heating device by analyzing the operating status of the instant heating pipe and the water pump.

[0040] The instant heating device according to the fourth aspect of the present invention may also have the following additional technical features:

[0041] In the above technical solution, the instant heating device also includes: a water inlet pipe, connected to the water pump; a water outlet pipe, connected to the instant heating pipe; an inlet water temperature detection component, arranged on the water inlet pipe, for detecting the inlet water temperature of the instant heating device; an outlet water temperature detection component, arranged on the outlet pipe, for detecting the outlet water temperature of the instant heating device; an instant heating pipe temperature detection component, arranged on the instant heating pipe, for detecting the instant heating pipe temperature of the instant heating device.

[0042] In this technical solution, the instant heating device further includes a water outlet pipe, a water outlet temperature detector, a water inlet pipe, a water inlet temperature detector, and a heating pipe temperature detector. The water outlet temperature detector, the water inlet temperature detector, and the heating pipe temperature detector are all electrically connected to the aforementioned working status diagnostic device. The water outlet temperature detector is disposed on the water outlet pipe to detect the outlet water temperature of the instant heating device. The water inlet temperature detector is disposed on the water inlet pipe to obtain the inlet water temperature of the instant heating device. The heating pipe temperature detector is disposed on the heating pipe to obtain the heating temperature of the heating pipe (i.e., the heat pipe temperature).

[0043] In the actual use of instant heating devices, problems with the water supply often occur due to incorrect connections of the inlet and outlet pipes, failure of components such as the heating pipe or water pump, etc., causing the device to operate abnormally with no or insufficient water. If the instant heating device continues to operate in this situation, it will cause damage to the components or internal pipes of the device, and may even cause safety accidents, reducing the reliability and safety of the device.

[0044] In this technical solution, the first operating state of the instant heating pipe and the second operating state of the water pump are obtained, and then the water inlet temperature of the instant heating device is obtained through the water inlet temperature detection component, the water outlet temperature of the instant heating device is obtained through the water outlet temperature detection component, and the temperature of the instant heating pipe is obtained through the instant heating pipe temperature detection component. On this basis, by jointly analyzing the first operating state, the second operating state, the water inlet temperature, the water outlet temperature and the instant heating pipe temperature obtained above, the current working state of the instant heating device is diagnosed, and the working state of the instant heating device is determined to be normal or abnormal. In this way, by jointly analyzing the operating state of the instant heating pipe, the operating state of the water pump and multiple water temperature data in the instant heating device, a rapid and accurate judgment of the state of the instant heating device is achieved, so that corresponding treatment measures can be taken in time when the working state of the instant heating device is abnormal, to avoid the instant heating device continuing to operate in an abnormal working state and causing damage to the internal parts or pipelines of the instant heating device, thereby improving the reliability and safety of the operation of the instant heating device.

[0067] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0068] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0069] The following combination Figures 1 to 16 , through specific embodiments and their application scenarios, the instant heating device and its working status diagnosis method and device, and the water treatment device provided in the embodiments of the present application are described in detail.

[0070] In some embodiments of the present invention, a method for diagnosing the working status of an instant heating device is proposed, such as Figure 1 As shown, the working status diagnosis method includes:

[0071] S102, acquiring water temperature data, i.e., a first operating state of the heat pipe and a second operating state of the water pump;

[0072] S104: jointly analyzing the first operating state, the second operating state, and the water temperature data to diagnose the operating state of the instant heating device.

[0073] The method for diagnosing the operating status of an instant heating device proposed in this embodiment is applicable to instant heating devices equipped with components such as an instant heating pipe, a water pump, and inlet and outlet water lines. In actual use, problems with the water supply of an instant heating device can often occur due to incorrect connections in the inlet and outlet water lines, or failure of components such as the instant heating pipe or water pump, causing the device to operate abnormally with or without water. Continuing to operate in this situation can damage the components or internal piping, and may even lead to safety issues, reducing the reliability and safety of the device.

[0074] Therefore, in the operating status diagnosis method of the instant heating device proposed in this embodiment, a first operating status of the instant heating pipe and a second operating status of the water pump are obtained. At the same time, multiple water temperature data in the instant heating device are obtained based on multiple temperature sensors installed inside the instant heating device. Then, by jointly analyzing the multiple water temperature data, the first operating status, and the second operating status, the current operating status of the entire instant heating device is diagnosed, and the operating status of the entire instant heating device is determined to be normal or abnormal. In this way, by jointly analyzing the operating status of the instant heating pipe, the operating status of the water pump, and the water temperature data in the instant heating device, a rapid and accurate judgment of the entire state of the instant heating device is achieved, so that corresponding treatment measures can be taken in a timely manner when the instant heating device is in an abnormal operating state, avoiding damage to the internal parts or pipelines of the instant heating device caused by the instant heating device continuing to operate in an abnormal operating state, thereby improving the reliability and safety of the operation of the instant heating device.

[0075] The first operating state represents the operating state of the heat pipe, and includes a heating state and a non-heating state, corresponding to the heating and non-heating operating modes of the heat pipe, respectively. The second operating state represents the operating state of the water pump, and includes an operating state and a non-operating state, corresponding to the running and stopping operating modes of the water pump, respectively.

[0076] Furthermore, the above-mentioned water temperature data includes temperature data such as the water inlet temperature and the water outlet temperature of the heating pipe. It is understandable that during the operation of the heating device, the operating status of the various components of the heating device (such as the water pump and the heating pipe) affects the water temperature data in the heating device. Depending on the different operating status of the various components of the heating device, the water temperature data in the heating device is also different, or in other words, there is a certain correlation between the water temperature data of the heating device and the operating status of the various components of the heating device. Therefore, by jointly analyzing multiple data such as the operating status of the heating pipe, the operating status of the water pump and the water temperature data in the heating device, and then combining the corresponding relationship between the various data under normal working conditions, the working status of the entire heating device can be quickly and accurately diagnosed, thereby improving the reliability and safety of the operation of the heating device.

[0077] In addition, it should be noted that the above-mentioned water temperature data should be obtained later than the above-mentioned first operating state and the second operating state of the water pump. Specifically, the water temperature data of the instant heating device is obtained after the first operating state of the instant heating pipe and the second preset state of the water pump are obtained for a preset time. The water temperature data in the instant heating device is affected by the operating state of each component of the instant heating device (such as the water pump and the instant heating pipe), or in other words, there is a certain correlation between the water temperature data of the instant heating device and the operating state of each component of the instant heating device. Therefore, obtaining the water temperature data after the first operating state and the second operating state are obtained for a preset time can ensure that the currently obtained water temperature data is the water temperature data after being affected by the first operating state and the second operating state, that is, it is ensured that the currently obtained water temperature data is associated with the first operating state and the second operating state. Based on this, the first operating state representing the working state of the instant heating pipe, the second operating state representing the working state of the water pump, and multiple water temperature data can be jointly analyzed in the instant heating device, so as to quickly and accurately diagnose the working state of the entire device according to the analysis results.

[0078] To prevent damage to the components or internal piping of the instant heating device caused by prolonged operation of the device under abnormal operating conditions, the preset time should not be too long. Specifically, due to the rapid operating performance of the instant heating device, the preset time can be a shorter time such as 3 seconds, 4 seconds, or 5 seconds, without specific limitation.

[0079] In summary, the working status diagnosis method of the instant heating device proposed in the embodiment of the present invention jointly analyzes multiple data such as the operating status of the instant heating pipe, the operating status of the water pump, and the water temperature data in the instant heating device, and quickly and accurately diagnoses the working status of the entire instant heating device through the correlation between the various data, so as to take corresponding treatment measures in time when the instant heating device is working abnormally, avoiding the instant heating device continuing to work in an abnormal working state and causing damage to the internal parts or pipelines of the instant heating device, thereby improving the reliability and safety of the operation of the instant heating device.

[0080] In some embodiments of the present invention, Figure 2 As shown, the working status diagnosis method includes:

[0081] S202, acquiring water temperature data, i.e., a first operating state of the heat pipe and a second operating state of the water pump;

[0082] S204, determining whether the current state is the first operating state is the heating state and the second operating state is the running state. If the determination result is yes, executing S206; if the determination result is no, ending the process;

[0083] S206, when the outlet water temperature of the instant heating device is greater than the inlet water temperature, and the heating temperature of the instant heating pipe is also greater than the inlet water temperature, it is determined that the instant heating device is operating normally;

[0084] S208: When the outlet water temperature is less than or equal to the inlet water temperature, or the heating temperature of the instant heating pipe is less than or equal to the inlet water temperature, it is determined that the working state of the instant heating device is abnormal.

[0085] In this embodiment, when the heating pipe is in a heating state and the water pump is in operation, the operating state of the entire heating device is diagnosed based on the comparison results between the inlet and outlet water temperatures of the heating device, as well as the comparison results between the inlet water temperature and the heating temperature of the heating pipe. Specifically, if the outlet water temperature of the heating device is greater than the inlet water temperature, and the heating temperature of the heating pipe is also greater than the inlet water temperature, the heating device is determined to be in a normal operating state. If the outlet water temperature is less than or equal to the inlet water temperature, or the heating temperature of the heating pipe is less than or equal to the inlet water temperature, the heating device is determined to be in an abnormal operating state. In this way, when the heating pipe is in a heating state and the water pump is in operation, the operating state of the entire heating device can be quickly and accurately diagnosed based on the comparison results between the inlet and outlet water temperatures of the heating device, as well as the comparison results between the inlet water temperature and the heating temperature of the heating pipe, thereby improving the reliability and safety of the heating device.

[0086] Specifically, in this embodiment, when it is determined that the instant heating device is in an abnormal working state, the specific abnormal condition of the instant heating device can be diagnosed and processed from four aspects: the inlet and outlet water pipes are installed upside down, the instant heating pipes are damaged or connected incorrectly, the water pump is damaged, and the temperature sensor is damaged or connected incorrectly.

[0087] Furthermore, in this embodiment, upon determining that the instant heating device is currently in an abnormal operating state, the device can be controlled to automatically enter an abnormality handling procedure. Specifically, the device can be prevented from continuing to operate in an abnormal operating state by controlling the device to stop discharging water, controlling the heating pipes of the device to stop heating, or controlling the water pump of the device to stop running. This prevents damage to the components or internal piping of the device, thereby improving the reliability and safety of the device and ensuring its service life.

[0088] In some embodiments of the present invention, Figure 3 As shown, the working status diagnosis method includes:

[0089] S302, acquiring water temperature data, i.e., a first operating state of the heat pipe and a second operating state of the water pump;

[0090] S304, determining whether the current state is the first operating state being the heating state and the second operating state being the non-operating state; if the determination result is yes, executing S306; if the determination result is no, ending the process;

[0091] S306, when the heating temperature of the instant heating pipe is greater than the inlet water temperature, it is determined that the instant heating device is operating normally;

[0092] S308: When the heating temperature of the instant heating pipe is less than or equal to the inlet water temperature, it is determined that the working state of the instant heating device is abnormal.

[0093] In this embodiment, when the instant heating pipe is in a heating state and the water pump is in a non-operating state, the working state of the instant heating device is diagnosed directly based on the comparison result between the water inlet temperature of the instant heating device and the heating temperature of the instant heating pipe, so as to determine whether the instant heating device is in an abnormal state or a normal state. The heating temperature of the instant heating pipe is the instant heating pipe temperature. Specifically, when the instant heating pipe temperature is greater than the above-mentioned water inlet temperature, the current working state of the instant heating device is determined to be a normal state of the entire device, and when the above-mentioned instant heating pipe temperature is less than or equal to the above-mentioned water inlet temperature, the current working state of the instant heating device is determined to be an abnormal state of the entire device. In this way, when the working state of the instant heating pipe is a heating state and the working state of the water pump is in a non-operating state, the working state of the entire device is quickly and accurately diagnosed directly based on the comparison result between the obtained water inlet temperature and the heating temperature of the instant heating pipe, thereby improving the reliability and safety of the operation of the instant heating device.

[0094] Specifically, in this embodiment, when it is determined that the instant heating device is in an abnormal working state, the specific abnormal condition of the instant heating device can be diagnosed and processed from two aspects: the instant heating pipe is damaged or connected incorrectly, and the temperature sensor is damaged or connected incorrectly.

[0095] Furthermore, in this embodiment, upon determining that the instant heating device is currently in an abnormal operating state, the device can be controlled to automatically enter an abnormality handling procedure. Specifically, the device can be controlled to stop discharging water and to stop heating the heating pipes thereof, thereby preventing the device from continuing to operate in an abnormal operating state. This prevents damage to the components or internal piping of the device, thereby improving the reliability and safety of the device and ensuring its service life.

[0096] In some embodiments of the present invention, Figure 4 As shown, the working status diagnosis method includes:

[0097] S402, acquiring water temperature data, i.e., a first operating state of the heat pipe and a second operating state of the water pump;

[0098] S404, determining whether the first operating state is a non-heating state, if the determination result is yes, executing S406, if the determination result is no, ending the process;

[0099] S406, obtaining a first difference value based on the difference between the first outlet water temperature and the first inlet water temperature at the first moment;

[0100] S408, obtaining a second difference value based on the difference between the second outlet water temperature and the second inlet water temperature at the second moment;

[0101] S410, determining an actual temperature rise rate of change according to the first difference, the second difference, and the time interval between the first moment and the second moment;

[0102] S412: Diagnose the working state of the instant heating device according to a comparison result between the actual temperature rise change rate and the preset temperature rise change rate.

[0103] In this embodiment, when the instant heating pipe is in a non-heating state, the actual temperature rise rate of the instant heating device is calculated without considering the operating state of the water pump. The current operating state of the instant heating device is then diagnosed based on a comparison of the actual temperature rise rate with a preset temperature rise rate. Specifically, a first outlet water temperature and a first inlet water temperature of the instant heating device at a first moment are obtained, and the difference between the two is calculated to obtain a first difference (i.e., a first temperature rise). A second outlet water temperature and a second inlet water temperature of the instant heating device at a second moment are obtained, and the difference between the outlet water temperature and the inlet water temperature of the instant heating device at this moment is calculated to obtain a second difference (i.e., a second temperature rise). Based on this, the temperature rise value of the instant heating device from the first moment to the second moment is determined based on the obtained first and second differences. Furthermore, the actual temperature rise rate of the instant heating device from the first moment to the second moment is determined based on the time interval between the first and second moments. Based on the comparison of the obtained actual temperature rise rate with the preset temperature rise rate, the operating state of the instant heating device is diagnosed. In this way, when it is determined that the instant heating pipe is in a non-heating state, there is no need to consider the operating state of the water pump, and the actual temperature rise rate of the instant heating device can be directly obtained. Then, based on the comparison result of the actual temperature rise rate compared with the preset temperature rise rate, the working state of the entire instant heating device can be quickly and accurately diagnosed, thereby improving the reliability and safety of the operation of the instant heating device.

[0104] The preset temperature rise change rate is related to the current operating power and water outlet flow rate of the instant heating device. Specifically, when the instant heating device is in a normal heating and water outlet state, the normal change rate of the temperature rise of the instant heating device (the difference between the outlet water temperature and the inlet water temperature of the instant heating device) under different power and flow rate operating conditions is obtained, and this normal change rate is determined as the standard temperature rise change rate under the current power and flow rate combination. Then, by weighting the standard temperature rise change rate or superimposing a temperature value, the preset temperature rise change rate of the instant heating device under the current power and flow rate operating condition combination when the instant heating pipe is in a non-heating state is obtained.

[0105] In addition, in actual application, as shown in Table 1, the preset temperature rise change rates of the instant heating device under different power and flow rate operating condition combinations can be obtained according to the above method, and a matching relationship between the preset temperature rise change rates and the operating condition combinations can be established. Then, the preset temperature rise change rates under all operating conditions can be pre-stored in the memory of the instant heating device in the form of a table or document. In this way, if it is determined that the instant heating pipe of the instant heating device is in a non-heating state, the preset temperature rise change rate that matches the current power and water flow rate can be directly searched from the pre-stored table or document based on the current operating power and water flow rate of the instant heating device. Then, the operating status of the entire instant heating device can be diagnosed based on the comparison result of the actual temperature rise change rate with the preset temperature rise change rate.

[0106] Table 1: Summary of preset temperature rise rates

[0107] Power\flow rate 300ml / second 400ml / second 500ml / second 1000W 10℃ / second 9℃ / second 8℃ / second 1200W 12℃ / second 11℃ / second 9℃ / second 1400W 14℃ / second 13℃ / second 10℃ / second 1800W 17℃ / second 15℃ / second 11℃ / second

[0108] In some embodiments of the present invention, Figure 5 As shown, the working status diagnosis method includes:

[0109] S502, acquiring water temperature data, i.e., a first operating state of the heat pipe and a second operating state of the water pump;

[0110] S504, determining whether the first operating state is a non-heating state, if the determination result is yes, executing S506, if the determination result is no, ending the process;

[0111] S506, obtaining a first difference value based on the difference between the first outlet water temperature and the first inlet water temperature at the first moment;

[0112] S508, obtaining a second difference value based on the difference between the second outlet water temperature and the second inlet water temperature at the second moment;

[0113] S510, determining an actual temperature rise rate of change according to the first difference, the second difference, and the time interval between the first moment and the second moment;

[0114] S512, when the preset temperature rise change rate is greater than or equal to the actual temperature rise change rate, it is determined that the working state of the instant heating device is normal;

[0115] S514: When the preset temperature rise rate of change is less than the actual temperature rise rate of change, it is determined that the working state of the instant heating device is abnormal.

[0116] In this embodiment, when the instant heating pipe is in a non-heating state, the operating state of the instant heating device is diagnosed based on the comparison result of the actual temperature rise rate of change with the preset temperature rise rate of change. Specifically, if the preset temperature rise rate of change is greater than or equal to the actual temperature rise rate of change, the operating state of the instant heating device is determined to be normal, and if the preset temperature rise rate of change is less than the actual temperature rise rate of change, the operating state of the instant heating device is determined to be abnormal. In this way, when determining that the instant heating pipe is in a non-heating state, the actual temperature rise rate of change of the instant heating device is directly obtained based on the change in the temperature rise of the instant heating device over time, without considering the operating state of the water pump. The operating state of the entire instant heating device can then be quickly and accurately diagnosed based on the comparison result between the actual temperature rise rate of change and the preset temperature rise rate of change, thereby improving the reliability and safety of the operation of the instant heating device.

[0117] The preset temperature rise rate of change is related to the current power and water outlet flow rate of the instant heating device. In actual application, as shown in Table 1 above, the preset temperature rise rate of change for the instant heating device under different power and flow rate operating conditions can be obtained, and a matching relationship between the preset temperature rise rate of change and the operating condition combination can be established. The preset temperature rise rate of change for all operating conditions can then be pre-stored in the memory of the instant heating device in the form of a table or document for direct subsequent retrieval and use.

[0118] For example, the instant heating pipe of the instant heating device is in a non-heating state, the current power of the instant heating device is 1200W, and the flow rate is 400ml / s. The preset temperature rise rate under the current operating condition combination is found in Table 1 to be 11°C / s. At this time, if the current outlet water temperature of the instant heating device is detected to be 55°C and the inlet water temperature is 33°C, and 2 seconds later, the outlet water temperature of the instant heating device is detected to be 99°C and the inlet water temperature is 33°C, then the actual temperature rise rate of the instant heating device can be calculated to be 22°C / s. 22°C / s>11°C / s, that is, the preset temperature rise rate is less than the current actual temperature rise rate. At this time, it is determined that the entire operating state of the instant heating device is abnormal.

[0119] Furthermore, in this embodiment, upon determining that the instantaneous heating device is currently in an abnormal operating state, the device can be controlled to automatically enter an abnormality handling procedure. Specifically, the device can be controlled to stop discharging water or to stop the water pump of the instantaneous heating device to prevent continued operation of the device in an abnormal operating state, thereby preventing damage to components or internal piping within the device. This improves the reliability and safety of the device's operation and ensures the device's service life.

[0120] In some embodiments of the present invention, Figure 6 As shown, the working status diagnosis method includes:

[0121] S602, obtaining a first operating state of the heating pipe and a second operating state of the water pump, and obtaining water temperature data after a preset time;

[0122] S604, determining whether the current state is the first operating state is the heating state and the second operating state is the running state, if the determination result is yes, executing S606, if the determination result is no, executing S608;

[0123] S606: Determine whether the water temperature data satisfies the conditions that the outlet water temperature is greater than the inlet water temperature, and the heating temperature of the instant heating pipe is greater than the inlet water temperature. If so, the instant heating device is determined to be operating normally, and the process ends. If not, the instant heating device is determined to be operating abnormally, and S622 is executed.

[0124] S608, determining whether the current state is the first operating state being the heating state and the second operating state being the non-operating state; if the determination result is yes, executing S610; if the determination result is no, executing S612;

[0125] S610, determining whether the heating temperature of the instant heating pipe is greater than the inlet water temperature. If so, the instant heating device is determined to be operating normally, and the process ends. If not, the instant heating device is determined to be operating abnormally, and S622 is executed.

[0126] S612, obtaining a first difference value based on a difference between a first outlet water temperature and a first inlet water temperature at a first moment;

[0127] S614, obtaining a second difference value based on the difference between the second outlet water temperature and the second inlet water temperature at the second moment;

[0128] S616, determining an actual temperature rise rate of change based on the first difference, the second difference, and the time interval between the first moment and the second moment;

[0129] S618, searching for a preset temperature rise change rate corresponding to the current power and the current water outlet flow rate of the instant heating device;

[0130] S620, determining whether the actual temperature rise rate of change is greater than a preset temperature rise rate of change. If so, it is determined that the operating state of the instant heating device is abnormal, and S622 is executed. If not, it is determined that the operating state of the instant heating device is normal, and the process ends.

[0131] S622, controlling the instant heating device to enter an abnormality handling procedure.

[0132] In this embodiment, a first operating state of the heating pipe and a second operating state of the water pump are obtained, and after a preset time interval, water temperature data in the heating device is obtained. Then, by jointly analyzing the obtained first operating state, second operating state, and water temperature data, the current operating state of the heating device is diagnosed, and the operating state of the heating device is determined to be normal or abnormal. The first operating state includes a heating state and a non-heating state, the second operating state includes an operating state and a non-operating state, and the water temperature data includes the inlet water temperature and outlet water temperature of the heating pipe, as well as the water temperature of the heating pipe (i.e., the heating temperature of the heating pipe). In this way, by jointly analyzing the operating state of the heating pipe, the operating state of the water pump, and multiple water temperature data in the heating device, a rapid and accurate judgment of the overall state of the heating device is achieved, so that corresponding treatment measures can be taken in a timely manner when the operating state of the heating device is abnormal, thereby preventing the heating device from continuing to operate in an abnormal operating state and causing damage to internal parts or pipelines of the heating device, thereby ensuring the service life of the heating device and improving the reliability and safety of the heating device.

[0133] In this embodiment, specifically, when it is determined that the instant heating pipe is in a heating state and the water pump is in an operating state, it is determined whether the water temperature data of the instant heating device meets the preset conditions that the outlet water temperature is greater than the inlet water temperature and the heating temperature of the instant heating pipe is greater than the inlet water temperature. If the conditions are met, it is determined that the working state of the instant heating device is normal; if the conditions are not met, it is determined that the working state of the instant heating device is abnormal.

[0134] Furthermore, when it is determined that the instant heating pipe is in a heating state and the water pump is in a non-operating state, it is further determined whether the heating temperature of the instant heating pipe is greater than the water inlet temperature. If the heating temperature of the instant heating pipe is greater than the water inlet temperature, it is determined that the working state of the instant heating device is normal. If the heating temperature of the instant heating pipe is less than or equal to the water inlet temperature, it is determined that the working state of the instant heating device is abnormal.

[0135] Furthermore, when it is determined that the operating status of the instant heating pipe and the water pump does not satisfy the above two combinations, that is, when the instant heating pipe is in a non-heating state and the water pump is in an operating state or a non-operating state, the current actual temperature rise change rate of the instant heating device is determined, and based on the current power and water outlet flow rate of the instant heating device, the preset temperature rise change rate under the current working conditions is found, and then the above actual temperature rise change rate is compared with the preset temperature rise change rate. When the preset temperature rise change rate is less than the actual temperature rise change rate, the working status of the instant heating device is determined to be abnormal. When the preset temperature rise change rate is greater than or equal to the actual temperature rise change rate, the working status of the instant heating device is determined to be normal.

[0136] Furthermore, upon determining that the instantaneous heating device is currently in an abnormal operating state, the device can be controlled to automatically enter an abnormality handling procedure. Specifically, the device can be controlled to stop discharging water, stop heating the heating pipes, or stop the water pump from running to prevent the device from continuing to operate in an abnormal operating state. This prevents damage to the device's components or internal piping, improves the reliability and safety of the device's operation, and ensures the device's service life.

[0137] In some embodiments of the present invention, Figure 7 As shown, the working status diagnosis method includes:

[0138] S702, obtaining a first operating state of the instant heating pipe and a second operating state of the water pump, and after a preset time, obtaining the water inlet temperature, water outlet temperature, and temperature of the instant heating pipe of the instant heating device;

[0139] S704, determining whether the current state is the first operating state is the heating state and the second operating state is the running state. If the determination result is yes, execute S706; if the determination result is no, execute S708;

[0140] S706, comparing the outlet water temperature, inlet water temperature, and instant heating pipe temperature in pairs, and diagnosing the working status of the instant heating device based on the comparison results;

[0141] S708, determining whether the current state is the first operating state being the heating state and the second operating state being the non-operating state; if the determination result is yes, executing S706; if the determination result is no, executing S710;

[0142] S710: Diagnose the working state of the instant heating device according to a comparison result of the actual temperature rise change rate of the instant heating device and the preset temperature rise change rate.

[0143] In this embodiment, the first operating state of the instant heating pipe and the second operating state of the water pump are obtained. After a preset time, the current water inlet temperature, water outlet temperature and instant heating pipe temperature of the instant heating device are obtained, and then the specific operating states of the instant heating pipe and the water pump are judged and analyzed, and the working state of the entire instant heating device is diagnosed step by step according to different situations.

[0144] In the first case, the heat pipe is in the heating state and the water pump is in the running state. The working state of the instant heating device is diagnosed based on the comparison results among the outlet water temperature, inlet water temperature and the instant heating pipe temperature of the instant heating device.

[0145] Specifically, when the outlet water temperature is lower than the inlet water temperature, and the inlet water temperature is higher than the instant heating pipe temperature, and the instant heating pipe temperature is lower than the outlet water temperature; when the outlet water temperature is lower than the inlet water temperature, and the inlet water temperature is higher than the instant heating pipe temperature, and the instant heating pipe temperature is higher than the outlet water temperature; when the outlet water temperature is lower than the inlet water temperature, and the inlet water temperature is lower than the instant heating pipe temperature, and the outlet water temperature is lower than the instant heating pipe temperature; and when the outlet water temperature is higher than the inlet water temperature, and the inlet water temperature is higher than the instant heating pipe temperature, and the outlet water temperature is higher than the instant heating pipe temperature, the above four temperature comparison results all determine that the working state of the entire instant heating device is abnormal.

[0146] Furthermore, when the outlet water temperature is greater than the inlet water temperature, and the instant heat pipe temperature is greater than the inlet water temperature, and the outlet water temperature is greater than the instant heat pipe temperature; and when the outlet water temperature is greater than the inlet water temperature, and the instant heat pipe temperature is greater than the inlet water temperature, and the outlet water temperature is less than the instant heat pipe temperature, the above two temperature comparison results both determine that the working state of the instant heat device is normal.

[0147] Furthermore, when the outlet water temperature is lower than the inlet water temperature, and the inlet water temperature is lower than the instant heating pipe temperature, and the outlet water temperature is higher than the instant heating pipe temperature; and when the outlet water temperature is higher than the inlet water temperature, and the inlet water temperature is higher than the instant heating pipe temperature, and the outlet water temperature is lower than the instant heating pipe temperature, the temperature comparison results of the above two situations do not exist in the actual application process, so no judgment is made.

[0148] The second situation: the heat pipe is in the heating state and the water pump is in the non-operating state. The working state of the instant heating device is diagnosed based on the comparison results among the outlet water temperature, inlet water temperature and the instant heating pipe temperature of the instant heating device.

[0149] Specifically, when the outlet water temperature is lower than the inlet water temperature, and the inlet water temperature is higher than the instant heating pipe temperature, and the instant heating pipe temperature is lower than the outlet water temperature; when the outlet water temperature is lower than the inlet water temperature, and the inlet water temperature is higher than the instant heating pipe temperature, and the outlet water temperature is lower than the instant heating pipe temperature; and when the outlet water temperature is higher than the inlet water temperature, and the inlet water temperature is higher than the instant heating pipe temperature, and the outlet water temperature is higher than the instant heating pipe temperature, the above three temperature comparison results all determine that the working state of the entire instant heating device is abnormal.

[0150] Furthermore, when the outlet water temperature is lower than the inlet water temperature, and the instant heat pipe temperature is higher than the inlet water temperature, and the outlet water temperature is lower than the instant heat pipe temperature; when the outlet water temperature is higher than the inlet water temperature, and the instant heat pipe temperature is higher than the inlet water temperature, and the outlet water temperature is higher than the instant heat pipe temperature; and when the outlet water temperature is higher than the inlet water temperature, and the instant heat pipe temperature is higher than the inlet water temperature, and the outlet water temperature is lower than the instant heat pipe temperature, the above three temperature comparison results all determine that the working state of the instant heat device is normal.

[0151] Furthermore, when the outlet water temperature is lower than the inlet water temperature, and the inlet water temperature is lower than the instant heating pipe temperature, and the outlet water temperature is higher than the instant heating pipe temperature; and when the outlet water temperature is higher than the inlet water temperature, and the inlet water temperature is higher than the instant heating pipe temperature, and the outlet water temperature is lower than the instant heating pipe temperature, the temperature comparison results of the above two situations do not exist in the actual application process, so no judgment is made.

[0152] The third situation: the heat pipe is in a non-heating state and the water pump is in a running state. The working state of the instant heating device is diagnosed based on the comparison result of the actual temperature rise change rate of the instant heating device with the preset temperature rise change rate, where the above-mentioned temperature rise refers to the difference between the outlet water temperature and the inlet water temperature of the instant heating device.

[0153] Specifically, in this case, the six actual temperature comparison results between the outlet water temperature, inlet water temperature, and the temperature of the heating pipe of the instant heating device are further used to diagnose the operating status of the entire instant heating device by comparing the actual temperature rise rate of the instant heating device with the preset temperature rise rate of change. Specifically, in the case of the six actual temperature comparison results, if the preset temperature rise rate of change of the instant heating device is less than the actual temperature rise rate of change, the operating status of the entire instant heating device is determined to be abnormal. If the preset temperature rise rate of change of the instant heating device is greater than or equal to the actual temperature rise rate of change, the operating status of the entire instant heating device is determined to be normal.

[0154] Furthermore, when the outlet water temperature is lower than the inlet water temperature, and the inlet water temperature is lower than the instant heating pipe temperature, and the outlet water temperature is higher than the instant heating pipe temperature; and when the outlet water temperature is higher than the inlet water temperature, and the inlet water temperature is higher than the instant heating pipe temperature, and the outlet water temperature is lower than the instant heating pipe temperature, the temperature comparison results of the above two situations do not exist in the actual application process, so no judgment is made.

[0155] The fourth situation: the heat pipe is in a non-heating state and the water pump is in a non-operating state. The working state of the instant heating device is diagnosed based on the comparison result of the actual temperature rise change rate of the instant heating device and the preset temperature rise change rate, wherein the above-mentioned temperature rise refers to the difference between the outlet water temperature and the inlet water temperature of the instant heating device.

[0156] Specifically, in this case, the six actual temperature comparison results between the outlet water temperature, inlet water temperature, and the temperature of the heating pipe of the instant heating device are further used to diagnose the operating status of the entire instant heating device by comparing the actual temperature rise rate of the instant heating device with the preset temperature rise rate of change. Specifically, in the case of the six actual temperature comparison results, if the preset temperature rise rate of change of the instant heating device is less than the actual temperature rise rate of change, the operating status of the entire instant heating device is determined to be abnormal. If the preset temperature rise rate of change of the instant heating device is greater than or equal to the actual temperature rise rate of change, the operating status of the entire instant heating device is determined to be normal.

[0157] Furthermore, when the outlet water temperature is lower than the inlet water temperature, and the inlet water temperature is lower than the instant heating pipe temperature, and the outlet water temperature is higher than the instant heating pipe temperature; and when the outlet water temperature is higher than the inlet water temperature, and the inlet water temperature is higher than the instant heating pipe temperature, and the outlet water temperature is lower than the instant heating pipe temperature, the temperature comparison results of the above two situations do not exist in the actual application process, so no judgment is made.

[0234] Table 2: Instantaneous heating device working status diagnosis table

[0235]

[0236]

[0237]

[0238] In some embodiments of the present invention, Figure 9 As shown, a device 900 for diagnosing the working state of an instant heating device is proposed, and the device 900 includes:

[0239] An acquisition module 902 is used to acquire water temperature data, namely, a first operating state of the heat pipe and a second operating state of the water pump;

[0240] The processing module 904 is configured to diagnose the working state of the instant heating device according to the first operating state, the second operating state and the water temperature data.

[0241] The instant heating device operating status diagnostic device 900 proposed in this embodiment is used in an instant heating device equipped with components such as an instant heating pipe, a water pump, and inlet and outlet water lines. In actual use, problems with the water supply of the instant heating device can often occur due to incorrect connections in the inlet and outlet water lines, or failure of components such as the instant heating pipe or water pump, causing the device to enter an abnormal operating state with no or insufficient water. Continuing to operate in this situation can damage the components or internal piping of the instant heating device, and may even lead to safety issues, reducing the reliability and safety of the device.

[0242] Therefore, in the operating state diagnosis device 900 for an instant heating device proposed in this embodiment, the first operating state of the heating pipe, the second operating state of the water pump, and the water temperature data in the instant heating device are acquired by the acquisition module 902. The acquired first operating state, second operating state, and water temperature data are then jointly analyzed by the processing module 904 to diagnose the current operating state of the entire instant heating device and determine whether the operating state of the entire instant heating device is normal or abnormal. Thus, by jointly analyzing the operating state of the heating pipe, the operating state of the water pump, and the water temperature data in the instant heating device by the processing module 904, a rapid and accurate judgment of the entire state of the instant heating device is achieved, so that corresponding treatment measures can be taken in a timely manner when the instant heating device operates abnormally, thereby preventing the instant heating device from continuing to operate in an abnormal operating state and causing damage to internal parts or pipelines of the instant heating device, thereby improving the reliability and safety of the operation of the instant heating device.

[0243] The first operating state represents the operating state of the heat pipe, and includes a heating state and a non-heating state, corresponding to the heating and non-heating operating modes of the heat pipe, respectively. The second operating state represents the operating state of the water pump, and includes an operating state and a non-operating state, corresponding to the running and stopping operating modes of the water pump, respectively.

[0244] Furthermore, the above-mentioned water temperature data includes temperature data such as the water inlet temperature and the water outlet temperature of the heating pipe. It is understandable that during the operation of the heating device, the operating status of the various components of the heating device (such as the water pump and the heating pipe) affects the water temperature data in the heating device. Depending on the different operating status of the various components of the heating device, the water temperature data in the heating device is also different, or in other words, there is a certain correlation between the water temperature data of the heating device and the operating status of the various components of the heating device. Therefore, by jointly analyzing multiple data such as the operating status of the heating pipe, the operating status of the water pump and the water temperature data in the heating device, and then combining the corresponding relationship between the various data under normal working conditions, the working status of the entire heating device can be quickly and accurately diagnosed, thereby improving the reliability and safety of the operation of the heating device.

[0245] In addition, it should be noted that the water temperature data is obtained later than the first operating state of the instant heating pipe and the second operating state of the water pump. Specifically, after obtaining the first operating state of the instant heating pipe and the second preset state of the water pump for a preset time, the water temperature data of the instant heating device is obtained. The water temperature data in the instant heating device is affected by the operating state of each component of the instant heating device (such as the water pump and the instant heating pipe), or in other words, there is a certain correlation between the water temperature data of the instant heating device and the operating state of each component of the instant heating device. Therefore, obtaining the water temperature data after obtaining the first operating state and the second operating state for a preset time can ensure that the currently obtained water temperature data is the water temperature data after being affected by the first operating state and the second operating state, that is, it ensures that the currently obtained water temperature data is associated with the first operating state and the second operating state. Based on this, 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 device can be jointly analyzed, so as to quickly and accurately diagnose the working state of the entire device according to the analysis results.

[0246] To prevent damage to the components or internal piping of the instant heating device caused by prolonged operation of the device under abnormal operating conditions, the preset time should not be too long. Specifically, due to the rapid operating performance of the instant heating device, the preset time can be a shorter time such as 3 seconds, 4 seconds, or 5 seconds, without specific limitation.

[0247] In summary, the working status diagnosis device 900 of the instant heating device proposed in the embodiment of the present invention, through the processing module 904 therein, jointly analyzes multiple data such as the operating status of the instant heating pipe, the operating status of the water pump and the water temperature data in the instant heating device, and quickly and accurately diagnoses the working status of the entire instant heating device through the correlation between the various data, so as to take corresponding processing measures in time when the instant heating device is working abnormally, avoiding the instant heating device continuing to work in an abnormal working state and causing damage to the internal parts or pipelines of the instant heating device, thereby improving the reliability and safety of the operation of the instant heating device.

[0248] In this embodiment, when the first operating state is the heating state and the second operating state is the running state, the water temperature data includes the inlet water temperature and the outlet water temperature. The processing module 904 can be specifically used to: when the outlet water temperature is greater than the inlet water temperature and the heating temperature of the instant heat pipe is greater than the inlet water temperature, determine that the working state of the entire instant heat device is normal; when the outlet water temperature is less than or equal to the inlet water temperature, or the heating temperature is less than or equal to the inlet water temperature, determine that the working state of the entire instant heat device is abnormal.

[0249] In this embodiment, when the first operating state is the heating state and the second operating state is the non-operating state, the water temperature data includes the inlet water temperature, and the processing module 904 can be specifically used to: when the heating temperature of the instant heating pipe is greater than the inlet water temperature, determine that the operating state of the instant heating device is normal; when the heating temperature is less than or equal to the inlet water temperature, determine that the operating state of the instant heating device is abnormal.

[0250] In this embodiment, when the first operating state is a non-heating state, the water temperature data includes the outlet water temperature, and the acquisition module 902 can also be used to: obtain a first difference based on the difference between the first outlet water temperature and the first inlet water temperature at the first moment; obtain a second difference based on the difference between the second outlet water temperature and the second inlet water temperature at the second moment; the processing module 904 can specifically be used to: determine the actual temperature rise change rate based on the first difference, the second difference and the time interval between the first moment and the second moment; and diagnose the working state of the instant heating device based on the comparison result of the actual temperature rise change rate and the preset temperature rise change rate.

[0251] In this embodiment, the processing module 904 can be specifically used to: when the preset temperature rise rate of change is greater than or equal to the actual temperature rise rate of change, determine that the working state of the instant heating device is normal; when the preset temperature rise rate of change is less than the actual temperature rise rate of change, determine that the working state of the instant heating device is abnormal.

[0252] In this embodiment, the preset temperature rise change rate is related to the power and water outlet flow rate of the instant heating device, and the processing module 904 is also used to: based on the current power and current water outlet flow rate of the instant heating device, find the preset temperature rise change rate that matches the current power and current water outlet flow rate.

[0253] In this embodiment, the acquisition module 902 is specifically used to obtain water temperature data of the instant heating device after obtaining the first operating state of the instant heating pipe and the second operating state of the water pump for a preset time.

[0254] In this embodiment, the working state diagnosis device further includes a control module for controlling the instant heating device to enter an abnormality handling program after determining that the working state of the instant heating device is abnormal.

[0255] The instant heating product having the working status diagnosis device 900 of the instant heating device in each embodiment of the present invention has the following advantages: 1. Energy saving. Heating is performed as needed, and there is no need for long-term hot water storage work such as heating and insulation inside the machine, which reduces energy loss. 2. The product volume is reduced and the spatial adaptability is high. Since there is no need for hot water storage inside the machine, the structural design can reduce the product volume. 3. Low cost. Since there is no need for water storage and hot filling and related heating detection components inside the machine, the product cost can be reduced. 4. Improved user experience. The user can set the target water outlet temperature as needed, and the temperature control module and processing module 904 inside the machine can quickly and accurately reach the target water outlet temperature by heating and adjusting the working parameters to meet the user's water outlet needs. 5. Reliable and safe operation. By jointly analyzing the operating status of the internal components of the processing module 904 and the water temperature data, a rapid and accurate diagnosis of the working status of the entire instant heating device can be achieved.

[0257] Memory 1002 , where programs or instructions are stored;

[0259] The instant heating device 1000 provided in this embodiment includes a memory 1002 and a processor 1004. When the program or instructions in the memory 1002 are executed by the processor 1004, the steps of the working status diagnosis method of the instant heating device in any of the above embodiments are implemented. Therefore, the instant heating device 1000 has all the beneficial effects of the working status diagnosis method of the instant heating device in any of the above embodiments, which will not be repeated here.

[0260] Specifically, the memory 1002 and the processor 1004 may be connected via a bus or other means. The processor 1004 may include one or more processing units, and the processor 1004 may be a central processing unit (CPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other chips.

[0261] In some embodiments of the present invention, Figure 11As shown, an instant heating device 1100 is proposed, wherein the instant heating device 1100 includes the working state diagnosis device 900 of the instant heating device in the above embodiment.

[0262] The instant heating device 1100 provided in the embodiment of the present invention includes the working status diagnosis device 900 of the instant heating device in the above embodiment. Therefore, the instant heating device 1100 has all the beneficial effects of the working status diagnosis device 900 of the instant heating device in any of the above embodiments, which will not be repeated here.

[0263] Furthermore, in this embodiment, Figure 11 、 Figure 12 、 Figure 13 as well as Figure 14 As shown, the instant heating device 1100 further includes an instant heating pipe 1102, a water pump 1104, a water outlet pipe 1106, an outlet water temperature detector 1108, a water inlet pipe 1110, an inlet water temperature detector (not shown), and an instant heating pipe temperature detector (not shown). The instant heating pipe 1102, the water pump 1104, the outlet water temperature detector 1108, the inlet water temperature detector, and the instant heating pipe temperature detector are all electrically connected to the above-mentioned working status diagnostic device. The outlet water temperature detector 1108 is provided on the outlet water pipe 1106 for detecting the outlet water temperature of the instant heating device 1100. The inlet water temperature detector is provided on the inlet water pipe 1110 for obtaining the inlet water temperature of the instant heating device 1100. The instant heating pipe temperature detector is provided on the instant heating pipe 1102 for obtaining the heating temperature of the instant heating pipe 1102 (i.e., the heat pipe temperature).

[0264] During the actual use of the instant heating device 1100, problems with the water supply of the instant heating device 1100 may often occur due to incorrect connections of the water inlet and outlet pipes, failure of components such as the instant heating pipe 1102 or the water pump 1104, etc., causing the instant heating device 1100 to enter an abnormal operating state with no or insufficient water. In this case, if the instant heating device 1100 continues to operate, it may damage the components or internal pipes of the instant heating device 1100, or even cause safety accidents, thereby reducing the operational reliability and safety of the instant heating device 1100.
