Description

Technical Field

[0001] This application relates to the field of waterway systems, for example, to an electric heating tube, an electric heating device, and a waterway system. Background Art

[0002] Devices or environments that require hot water supply are usually equipped with a hot water waterway system. In the current hot water waterway system, the temperature controller protection probe of the electric heating tube is often set at the bottom or the barrel wall of the electric heating tube to protect the electric heating tube.

[0003] However, when a failure occurs in the waterway system or when it is restarted after not being used for a long time, if the water level in the electric heating tube cannot completely cover the electric heating tube and the temperature controller protection probe is located below the water level, it will cause dry burning of the upper part of the electric heating tube, posing a safety hazard. Therefore, the safety degree of use of the electric heating tube in this waterway system is relatively low, and the safety detection accuracy is relatively low.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of this application, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0046] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other.

[0047] In some embodiments, in combination with Figures 1 to 5 As shown, an electric heating tube 1 is provided, including a tube body 100, a thermostat 110, and a water level detection device 120. The tube body 100 includes a heating cavity 102. The temperature sensing probe 112 of the thermostat 110 is located at the water outlet end 104 of the heating cavity 102 and extends from one side wall of the heating cavity 102 of the tube body 100 to the opposite side wall. The water level detection device 120 is arranged on the tube body 100 for detecting the water level in the heating cavity 102.

[0048] In the electric heating tube 1 provided by the embodiments of the present disclosure, the heating cavity 102 is used to cache water so as to heat the water inside the heating cavity 102. The water level detection device 120 is used to detect the water level in the heating cavity 102 to determine whether the water in the heating cavity 102 fills the entire heating cavity 102. When the water does not fill the entire heating cavity 102, it is determined that there is a dry burning phenomenon at a part of the electric heating tube 1 (the water outlet end 104 of the electric heating tube 1). By arranging the temperature sensing probe 112 of the thermostat 110 at the water outlet end 104 of the heating cavity 102 to detect the temperature of the water outlet end 104. When the temperature of the water outlet end 104 exceeds the temperature safety threshold, it is determined that there is overheating and dry burning at the water outlet end 104 of the electric heating tube 1, and there is a safety hazard. At the same time, the temperature sensing probe 112 of the thermostat 110 is extended from one side wall of the heating cavity 102 of the tube body 100 to the opposite side wall to increase the contact area between the temperature sensing probe 112 and the surrounding environment and improve the temperature detection sensitivity of the thermostat 110.

[0049] When the water level detection device 120 detects that the water in the heating cavity 102 does not fill the entire heating cavity 102 and the temperature of the water outlet end 104 of the heating cavity 102 exceeds the temperature safety threshold, it is determined that there is a safety hazard in the current electric heating process of the electric heating tube 1, which improves the safety detection accuracy of the electric heating tube 1, and further improves the use safety degree of the electric heating tube 1. In addition, by improving the temperature detection sensitivity of the thermostat 110, the safety detection accuracy of the electric heating tube 1 in the electric heating process is further improved.

[0050] Optionally, in combination with Figure 1 and Figure 2 As shown, the temperature sensing probe 112 of the thermostat 110 extends in a direction perpendicular to the axis of the tube body 100.

[0051] In this embodiment, the temperature sensing probe 112 is arranged to extend in a direction perpendicular to the axis of the pipe body 100, so as to increase the contact area between the temperature sensing probe 112 and the surrounding environment, improve the temperature detection sensitivity of the thermostat 110, and thus improve the safety detection sensitivity and accuracy of the electric heating tube 1 during the electric heating process.

[0052] In some embodiments, as shown in Figures 1 to 5 the water level detection device 120 includes a water level sensor 122 and / or a flow meter 124. By providing the water level sensor 122 and / or the flow meter 124, the water level inside the heating chamber 102 can be detected to determine whether the water in the heating chamber 102 fills the entire heating chamber 102, so as to determine whether there is a dry burning phenomenon in a part of the electric heating tube 1.

[0053] Optionally, as shown in Figure 1 the water level detection device 120 includes a water level sensor 122. The water level sensor 122 is arranged on the pipe body 100 and is located inside the heating chamber 102.

[0054] In this embodiment, by arranging the water level sensor 122 inside the heating chamber 102, the water level inside the heating chamber 102 can be detected, so as to determine whether the water in the heating chamber 102 fills the entire heating chamber 102, and to determine whether there is a dry burning phenomenon in a part of the electric heating tube 1. Specifically, when the water in the heating chamber 102 fills the entire heating chamber 102, it is determined that there is no dry burning phenomenon in the electric heating tube 1. When the water in the heating chamber 102 does not fill the entire heating chamber 102, it is determined that there is a local dry burning phenomenon in the electric heating tube 1.

[0055] Optionally, as shown in Figure 1 the water level sensor 122 is arranged on the side wall of the heating chamber 102 and extends from the water inlet end 106 to the water outlet end 104 of the heating chamber 102. By arranging the water level sensor 122 to extend from the water inlet end 106 to the water outlet end 104 of the heating chamber 102, the sensitivity and accuracy of water level detection can be improved, and further the sensitivity and accuracy of safety detection of the electric heating tube 1 can be improved.

[0056] It should be noted that according to the different types of the water level sensor 122, its installation method inside the heating chamber 102 is different. For the specific installation method of the water level sensor 122 inside the heating chamber 102, it needs to be specifically set by those skilled in the art according to the actual type of the water level sensor 122, and this application does not make any limitation. Exemplarily, the types of the water level sensor 122 include a float type water level sensor, a capacitance type water level sensor, an ultrasonic type water level sensor, a pressure type water level sensor, etc.

[0057] Optionally, as shown in Figure 3As shown, the water level detection device 120 includes a flow meter 124. The flow meter 124 is disposed at the water inlet end 106 of the pipe body 100.

[0058] In this embodiment, by installing the flow meter 124 at the water inlet end 106 of the pipe body 100, the water flow rate entering the heating chamber 102 is monitored in real time. Then, based on the water capacity of the heating chamber 102 (the volume of water that can be accommodated in the heating chamber 102), the water level change inside the heating chamber 102 is determined to determine whether the water in the heating chamber 102 fills the entire heating chamber 102, so as to determine whether there is a dry burning phenomenon in a part of the electric heating tube 1.

[0059] In practical applications, the flow meter 124 includes an electromagnetic flow meter, an ultrasonic flow meter, or a vortex flow meter.

[0060] Optionally, in combination with Figure 4 and Figure 5 As shown, the water level detection device 120 includes a water level sensor 122 and a flow meter 124. The water level sensor 122 is disposed on the pipe body 100 and is located inside the heating chamber 102. The flow meter 124 is disposed at the water inlet end 106 of the pipe body 100.

[0061] In this embodiment, by installing the water level sensor 122 and the flow meter 124 simultaneously, a comprehensive monitoring of the water level and water flow state inside the heating chamber 102 is achieved, improving the sensitivity and accuracy of the water level detection inside the heating chamber 102, and further improving the sensitivity and accuracy of the safety detection of the electric heating tube 1.

[0062] Specifically, the average value of the water levels obtained by detecting the water level sensor 122 and the flow meter 124 can be calculated as the final water level information to improve the sensitivity and accuracy of the water level detection inside the heating chamber 102.

[0063] Optionally, in combination with Figures 3 to 5 As shown, the electric heating tube 1 further includes a heating element 130. The heating element 130 is disposed inside the heating chamber 102 and is used to heat the water inside the heating chamber 102.

[0064] In this embodiment, the heating element 130 is disposed inside the heating chamber 102 to quickly generate a large amount of heat in a short time. Then, by transferring the heat to the water body flowing through the heating element 130, the heating of the water body inside the heating chamber 102 is achieved.

[0065] Optionally, in combination with Figures 3 to 5 As shown, the heating element 130 extends along the length direction of the pipe body 100.

[0066] In this embodiment, the heating element 130 is arranged to extend along the length direction of the pipe body 100, so as to form a uniform heating area in the heating cavity 102, ensure uniform heating of the water body, avoid the phenomenon of water temperature stratification, and improve the heating efficiency.

[0067] Optionally, the number of the heating elements 130 is multiple, and the multiple heating elements 130 are arranged at intervals in the heating cavity 102. In this embodiment, the heating efficiency of the electric heating pipe 1 is improved by increasing the number of the heating elements 130.

[0068] Optionally, the control output end of the temperature controller 110 is communicatively connected to the power supply end of the heating element 130, so as to control the start or stop of the heating element 130 according to the detected temperature information.

[0069] In this embodiment, by establishing a communication connection between the control output end of the temperature controller 110 and the power supply end of the heating element 130, the temperature controller 110 can not only monitor the temperature of the water outlet end 104 of the heating cavity 102, but also directly control the power supply state of the heating element 130 through this temperature. Since the temperature sensing probe 112 of the temperature controller 110 is arranged at the water outlet end 104 of the heating cavity 102, the outlet water temperature can be obtained more accurately, and the outlet water temperature more directly reflects the heating effect and the user's needs. When the outlet water temperature is lower than the temperature set value, the temperature controller 110 sends a start signal to the power supply end of the heating element 130 to make the heating element 130 start to work. When the outlet water temperature reaches or exceeds the temperature set value, the temperature controller 110 sends a stop signal to the power supply end of the heating element 130 to make the heating element 130 stop working. By establishing a communication connection between the control output end of the temperature controller 110 and the power supply end of the heating element 130, the working state of the electric heating pipe 1 is controlled in real time and accurately, ensuring the high efficiency and stability of the heating process.

[0070] Optionally, as shown in Figures 3 to 5 the electric heating pipe 1 further includes a controller 140. The information input end of the controller 140 is communicatively connected to the temperature controller 110 and the water level detection device 120 respectively, so as to receive the temperature information output by the temperature controller 110 and the water level information of the water level detection device 120 respectively. The control output end of the controller 140 is communicatively connected to the power supply end of the heating element 130, so as to control the conduction or disconnection of the power supply end of the heating element 130 according to the received temperature information and water level information.

[0071] In this embodiment, by setting the controller 140 as the core control unit of the electric heating tube 1, intelligent control of the working state of the electric heating tube 1 is realized, improving the accuracy and safety of the heating process. Specifically, the information input ends of the controller 140 are respectively communicatively connected to the temperature controller 110 and the water level detection device 120. The temperature controller 110 is responsible for monitoring the temperature of the water outlet end 104 of the heating chamber 102 and transmitting the temperature information to the controller 140 in real time. The water level detection device 120 is responsible for monitoring the water level in the heating chamber 102 and transmitting the water level information to the controller 140 in real time. After receiving the temperature information output by the temperature controller 110 and the water level information of the water level detection device 120, the controller 140 determines the working state of the heating element 130 according to the temperature information and the water level information. The control output end of the controller 140 is connected to the power supply end of the heating element 130. The controller 140 controls the conduction or disconnection of the power supply end of the heating element 130 according to the determined working state, realizing intelligent control of the power supply state of the heating element 130 and precise control of the heating process.

[0072] Exemplarily, after the controller 140 receives the temperature information output by the temperature controller 110 and the water level information of the water level detection device 120, if it is determined according to the water level information that the water in the heating chamber 102 does not fill the entire heating chamber 102, and it is determined according to the temperature information that the temperature of the water outlet end 104 exceeds the temperature safety threshold, the working state of the heating element 130 is determined to be stopped, and then the power supply end of the heating element 130 is controlled to disconnect to stop the heating process. If it is determined according to the water level information that the water in the heating chamber 102 does not fill the entire heating chamber 102, and it is determined according to the temperature information that the temperature of the water outlet end 104 does not exceed the temperature safety threshold, the working state of the heating element 130 is determined to be started, and then the power supply end of the heating element 130 is controlled to conduct to continue the heating process. If it is determined according to the water level information that the water in the heating chamber 102 fills the entire heating chamber 102, and it is determined according to the temperature information that the temperature of the water outlet end 104 is lower than the temperature set value, the working state of the heating element 130 is determined to be started, and then the power supply end of the heating element 130 is controlled to conduct to continue the heating process. If it is determined according to the water level information that the water in the heating chamber 102 fills the entire heating chamber 102, and it is determined according to the temperature information that the temperature of the water outlet end 104 reaches or exceeds the temperature set value, the working state of the heating element 130 is determined to be stopped, and then the power supply end of the heating element 130 is controlled to disconnect to stop the heating process.

[0073] In practical applications, the controller 140 includes a microcontroller or a single-chip microcomputer. The microcontroller or the single-chip microcomputer has the advantages of small volume, low power consumption, strong programmability, etc. By writing corresponding control programs, the microcontroller or the single-chip microcomputer can receive and process temperature information and water level information, and control the power supply state of the heating element 130 according to the processing results to meet the control accuracy requirements.

[0074] Optionally, in combination with Figures 3 to 5As shown, the electric heating tube 1 further includes a power supply switch 150. One end of the power supply switch 150 is connected to the power supply end of the heating element 130, and the other end of the power supply switch 150 is communicatively connected to the control output end of the controller 140. The controller 140 controls the conduction or disconnection of the power supply switch 150 according to the received temperature information and water level information.

[0075] In this embodiment, one end of the power supply switch 150 is directly connected to the power supply end of the heating element 130, responsible for supplying electrical energy to the heating element 130. The other end of the power supply switch 150 is communicatively connected to the control output end of the controller 140, responsible for receiving the control signal from the controller 140. According to the control signal, the power supply switch 150 can intelligently switch between the conduction and disconnection states, thereby controlling the heating process of the heating element 130. By introducing the power supply switch 150, the safety protection of the electric heating tube 1 is improved. When the controller 140 detects a safety hazard, it can cut off the power supply switch 150 to quickly turn off the heating element 130 and achieve safety protection. This instant power-off function further improves the safety of the electric heating tube 1.

[0076] In some embodiments, in combination with Figure 4 As shown, an electric heating device 2 is provided, including the electric heating tube 1 as described in the above embodiment.

[0077] The electric heating device 2 provided by the embodiments of the present disclosure includes the electric heating tube 1 as described in the above embodiment. Therefore, the technical effects possessed by the electric heating tube 1 described in the above embodiment are all possessed by this embodiment, and will not be elaborated here.

[0078] Optionally, in combination with Figure 4 As shown, the electric heating device 2 further includes a water storage member 200. The water storage member 200 is connected to the water outlet end 104 of the tube body 100 through a pipeline. The water storage member 200 is used to store the water heated by the tube body 100, or to return the water stored therein to the tube body 100 to fill the heating cavity 102.

[0079] In this embodiment, the water storage member 200 can store the heated water, enabling users to quickly obtain hot water when needed without waiting for the heating process, improving the hot water supply efficiency and usability of the electric heating device 2. The water storage member 200 can return the water stored therein to the tube body 100 to fill the heating cavity 102, avoiding the phenomenon of local dry burning and further improving the usability safety of the electric heating device 2.

[0080] Optionally, in combination with Figure 4 As shown, the installation height of the water storage member 200 is higher than that of the tube body 100.

[0081] In this embodiment, by defining that the installation height of the water storage member 200 is higher than that of the pipe body 100, when the water inside the heating cavity 102 does not fill the entire heating cavity 102, the water in the water storage member 200 can flow back to the heating cavity 102 under the action of the height difference and gravity to fill the entire heating cavity 102, avoiding the phenomenon of local dry burning and further improving the use safety of the electric heating device 2.

[0082] Optionally, as shown in Figure 4 the electric heating device 2 further includes a water pump 210. The water pump 210 is arranged on the pipeline connected to the water storage member 200.

[0083] In this embodiment, by arranging the water pump 210 on the pipeline connected to the water storage member 200, the water flow is driven to flow along a predetermined path to provide power for the water flow circulation. Exemplarily, when the water flow flows from the heating cavity 102 to the water storage member 200, the rotation direction of the water pump 210 is defined as forward rotation, and vice versa, it is reverse rotation.

[0084] By controlling the forward rotation of the water pump 210, the hot water can be driven to flow quickly from the heating cavity 102 to the water storage member 200 and further to the hot water outlet, improving the hot water supply efficiency and the user experience. By controlling the reverse rotation of the water pump 210, the hot water in the water storage member 200 can be re-introduced into the electric heating pipe 1 for reheating to ensure that the water temperature in the water storage member 200 can meet the user's needs.

[0085] At the same time, by controlling the reverse rotation of the water pump 210, when the water inside the heating cavity 102 does not fill the entire heating cavity 102, the water in the water storage member 200 can be quickly guided back to the heating cavity 102 to fill the entire heating cavity 102, further improving the use safety of the electric heating device 2.

[0086] In some embodiments, as shown in Figure 4 the water pump 210 is arranged on the pipeline connected to the water outlet end of the water storage member 200. When the water pump 210 is arranged on the pipeline at the water outlet end of the water storage member 200, when the water pump 210 rotates forward, it can further accelerate the flow rate of driving the hot water to flow from the water storage member 200 to the hot water outlet, improving the hot water supply efficiency and the user experience. When the water pump 210 rotates in reverse, it can drive the external water source to enter the water storage member 200. After the water body fills the water storage member 200, it further flows back to the heating cavity 102 to fill the heating cavity 102. During the reheating process, the temperature of the pipe body 100 is reduced, improving the use safety of the electric heating device 2.

[0087] In some embodiments, the water pump 210 is disposed on the pipeline connected to the water inlet end of the water storage member 200. When the water pump 210 is disposed on the pipeline at the water inlet end of the water storage member 200, when the water pump 210 rotates forward, it can further accelerate the flow rate of driving hot water from the heating chamber 102 to the water storage member 200, so as to quickly fill the water storage member 200 and improve the hot water supply efficiency. When the water pump 210 rotates in reverse, it can directly drive the water in the water storage member 200 to quickly flow back to the heating chamber 102, fill the heating chamber 102, and during the reheating process, reduce the temperature of the pipe body 100 and improve the use safety of the electric heating device 2.

[0088] In some embodiments, as shown in Figure 4 the water pump 210 is communicatively connected to the control output end of the controller 140. By establishing a communication connection between the water pump 210 and the control output end of the controller 140, it is convenient for the controller 140 to intelligently control the working state of the water pump 210 according to the received temperature information and water level information, and improve the accuracy and safety of the heating process.

[0089] In a specific application, when the controller 140 determines according to the water level information that the water in the heating chamber 102 does not fill the entire heating chamber 102, and determines according to the temperature information that the temperature at the water outlet end 104 exceeds the temperature safety threshold, it controls the water pump 210 to rotate in reverse to quickly guide the water in the water storage member 200 back to the heating chamber 102 to fill the entire heating chamber 102, avoid local dry burning, and quickly cool the water outlet end 104 of the pipe body 100 at the same time. When the controller 140 determines according to the water level information that the water in the heating chamber 102 fills the entire heating chamber 102, and determines according to the temperature information that the temperature at the water outlet end 104 reaches or exceeds the temperature set value, it controls the water pump 210 to rotate forward to quickly guide the water in the heating chamber 102 to the water storage member 200 for storage, and improve the hot water heating and supply efficiency.

[0090] In a specific application, a temperature sensor 202 is installed in the water storage member 200, and the temperature sensor 202 is communicatively connected to the controller 140. When the controller 140 receives the temperature information detected by the temperature sensor 202 and determines that the temperature is lower than the temperature set value, it controls the water pump 210 to rotate in reverse to re-introduce the water in the water storage member 200 into the electric heating tube 1 for reheating, ensuring that the hot water temperature in the water storage member 200 can meet the user's needs.

[0091] It should be noted that the specific values of the temperature safety threshold and the temperature set value in this application need to be specifically set by technicians according to the actual product equipment or by users according to the usage requirements. The specific values of the temperature safety threshold and the temperature set value are not limited in this application.

[0092] Exemplarily, the temperature safety threshold is set to 60°C, 70°C, 80°C, or 90°C. The temperature set value is set to 45°C, 60°C, or 75°C.
