Description

Technical Field

[0001] This application relates to the field of hot water system technology, specifically to a heating water tank and its control method. Background Technology

[0002] Currently, some water tanks on the market with heating functions default to stopping heating when the water temperature reaches 100℃, ignoring the fact that the boiling point of water is affected by altitude and water quality. This causes the tank to continue heating after the water boils, resulting in a large amount of hot water steam and the heating device operating for extended periods, affecting the machine's lifespan. Other water tanks are set to stop heating at a temperature below 100℃, leading to incomplete heating that may not meet user needs and fails to sterilize the water. Therefore, designing a device that can intelligently determine the boiling point and automatically stop heating is a pressing technical problem that needs to be solved. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, this application provides a heating water tank and its control method. The specific technical solution is as follows:

The detection circuit is used to transmit electrical signal data to the control device. The electrical signal data is used to indicate the conductivity between the first detection element and the second detection element. The conductivity indicated by the electrical signal data is positively correlated with the humidity of the interval area between the first detection element and the second detection element.

[0006] In a possible implementation, both the first detection element and the second detection element are spaced apart from the water surface of the tank.

[0007] In a possible implementation, if the humidity in the interval region between the first detection element and the second detection element is lower than a preset humidity, the detection circuit forms an open circuit in the interval region between the first detection element and the second detection element.

[0009] In a possible implementation, the water tank is provided with at least two sets of the detection circuits, with the first detection element and the second detection element in any of the detection circuits spaced apart at the top of the water tank.

[0010] In a possible implementation, a plurality of temperature detection devices are also included, which are distributed in the inner cavity of the water tank and electrically connected to the control device respectively, for detecting the water temperature at different locations in the water tank.

[0011] In a possible implementation, at least some of the plurality of temperature detection devices are respectively disposed at the top and bottom of the water tank.

[0012] In a possible implementation, the water tank is equipped with a water level detection device, which is electrically connected to the control device.

[0013] In a possible implementation, the control device is configured to control the heating device to perform an operation that reduces heating efficiency when the received electrical signal data indicates that the conductivity has reached a first preset value.

[0014] On the other hand, this application provides a control method for a heating water tank, applied to the heating water tank described above, the control method comprising:

[0015] When the heating device is in heating mode, electrical signal data of the detection circuit is acquired, and the electrical signal data is used to indicate the conductivity between the first detection element and the second detection element;

[0016] If the conductivity indicated by the electrical signal data reaches a second preset value, the heating device is controlled to shut down.

[0017] Based on the above technical solution, this application has the following beneficial effects:

The detection circuit includes a first detection element and a second detection element, used to transmit electrical signal data to the control device. The electrical signal data is used to indicate the conductivity between the first and second detection elements. The conductivity indicated by the electrical signal data is positively correlated with the humidity of the interval area between the first and second detection elements. Thus, it is possible to determine whether the water in the tank has reached boiling point based on the humidity of the interval area, which helps to improve the accuracy of boiling point determination in different scenarios and enables automatic stopping of heating when the water boils, thereby improving the safety and versatility of the heated water tank.

[0031] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed description. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0032] Figure 1 This is a schematic diagram of the structure of a heated water tank provided in an embodiment of this application. The following is in conjunction with... Figure 1This application provides a heating water tank, comprising a water tank 1, a heating device 2 for heating water in the water tank 1, a detection circuit 3, and a control device. The heating device 2 and the detection circuit 3 are electrically connected to the control device. The detection circuit 3 includes a first detection element 31 and a second detection element 32, which are spaced apart and disposed on the top of the water tank 1. The detection circuit 3 transmits electrical signal data to the control device. The electrical signal data indicates the conductivity between the first detection element 31 and the second detection element 32. The conductivity indicated by the electrical signal data is positively correlated with the humidity of the interval area between the first detection element 31 and the second detection element 32. Understandably, during the heating process of the water in water tank 1, some water evaporates, increasing the humidity in the interval area between the first detection element 31 and the second detection element 32. This, in turn, increases the conductivity between the first detection element 31 and the second detection element 32. Thus, the humidity in the interval area can be determined based on the conductivity indicated by the electrical signal data, thereby determining whether the water in water tank 1 has reached boiling point. This enables real-time detection of the heating status of the water in water tank 1, allowing the heating water tank to automatically stop heating after heating water to boiling point at different altitudes. This improves the accuracy of boiling point determination and enhances the versatility of the heating water tank.

[0033] Specifically, the detection circuit 3 also includes a power supply. In one example, the output terminal of the power supply is connected to the first detection element 31, and the input terminal of the power supply is connected to the second detection element 32; in another example, the output terminal of the power supply is connected to the second detection element 32, and the input terminal of the power supply is connected to the first detection element 31. The power supply can provide a stable voltage or current to the detection circuit 3, so that the voltage or current between the first detection element 31 and the second detection element 32 can increase with the increase of humidity in the interval area, thereby accurately detecting the humidity change in the water tank 1.

[0034] Specifically, the detection circuit 3 is configured to transmit electrical signal data to the control device in real time during the heating process of the heating device 2. This enables real-time monitoring of humidity changes in the interval area between the first detection element 31 and the second detection element 32, which helps to improve the timeliness of humidity detection and thus improve the accuracy of judging the heating status of the water in the water tank 1.

[0035] In some embodiments, electrical signal data can indicate the resistivity between the first detection element 31 and the second detection element 32, which is negatively correlated with the humidity of the interval region between the first detection element 31 and the second detection element 32. It is understood that electrical signal data can be used to indicate any data that can characterize the conductivity between the first detection element 31 and the second detection element 32.

[0036] In a possible implementation, both the first detection element 31 and the second detection element 32 are spaced apart from the water surface of the water tank 1. Understandably, the conductivity of liquid water is much higher than that of water vapor. If the detection element is in contact with the water surface, the electrical signal data will be affected by the liquid water, causing the detection element to be unable to effectively detect changes in the conductivity of water vapor. Therefore, by spaced apart from the water surface, the influence of liquid water on the conductivity between the first detection element 31 and the second detection element 32 can be avoided, which helps improve the accuracy of determining the boiling state of water.

[0037] In a possible implementation, if the humidity in the interval region between the first detection element 31 and the second detection element 32 is lower than a preset humidity, the detection circuit 3 forms an open circuit in the interval region between the first detection element 31 and the second detection element 32. When the detection circuit 3 is open, it does not need to transmit electrical signal data to the control device, reducing unnecessary operation steps, which helps to reduce ineffective energy consumption and thus extend the device's lifespan. In one example, the preset humidity can be the humidity in the water tank 1 when the heating device 2 is not turned on.

[0038] Specifically, when the humidity in the interval between the first detection element 31 and the second detection element 32 reaches a preset humidity, the detection circuit 3 forms a path in the interval between the first detection element 31 and the second detection element 32. With the detection circuit 3 forming a path, it transmits electrical signal data to the control device. As the heating device 2 continuously heats the water in the water tank 1, the humidity in the interval between the first detection element 31 and the second detection element 32 increases, and the conductivity indicated by the electrical signal data increases. Therefore, the control device can determine whether the water has reached a boiling state based on the magnitude of the conductivity.

[0039] In a possible implementation, the first detection element 31 has a first fixed end and a first detection end, and the second detection element 32 has a second fixed end and a second detection end. The first fixed end and the second fixed end are spaced apart at the top of the water tank 1 to avoid contact between the first fixed end and the second fixed end, which could cause detection errors. There is a first distance between the first detection end and the water surface of the water tank 1, and the distance between the second detection end and the water surface is less than the first distance. When the first detection end and the second detection end are in contact with the water surface at the same time, the detection circuit 3 forms a closed loop with the water body, making it impossible for the detection circuit 3 to accurately detect the humidity change between the first detection end and the second detection end, and causing abnormal current in the detection circuit 3, increasing the risk of leakage.

[0040] In a possible implementation, the water tank 1 is equipped with at least two sets of detection circuits 3, both of which are electrically connected to the control device. The first detection element 31 and the second detection element 32 in any detection circuit 3 are spaced apart and positioned at the top of the water tank 1. This allows for the simultaneous detection of humidity at multiple locations within the water tank 1 and the transmission of multiple electrical signal data to the control device. This improves the accuracy of determining the heating status of the water in the water tank 1 and prevents malfunctions of the control device caused by uneven water vapor distribution.

[0041] Specifically, at least two sets of detection circuits 3 are distributed on the top of the water tank 1, and there is a preset interval between the first detection element 31 and the second detection element 32. The interval between at least two sets of detection circuits 3 is greater than the preset interval, so as to avoid the electrical signals of different detection circuits 3 from affecting each other and causing detection errors.

[0042] In a possible implementation, the first detection element 31 is a first probe, and the second detection element 32 is a second probe. The first probe and the second probe are spaced apart and arranged on the top of the water tank 1. In this way, setting the detection element as a probe can realize direct contact detection, reduce response time, improve the accuracy of humidity detection, and the probe structure is simple, which helps to reduce the manufacturing cost of the device.

[0043] In a possible implementation, multiple temperature detection devices 4 are also included. These devices are distributed within the inner cavity of the water tank 1 and are electrically connected to a control device to detect the water temperature at different locations within the water tank 1. In this way, the multiple temperature detection devices 4 can transmit the water temperature at different locations within the water tank 1 to the control device. The control device can then determine whether the water temperature distribution in the water tank 1 is uniform based on the water temperature at different locations, and further adjust the heating device 2 according to the water temperature distribution to avoid uneven water temperature distribution causing the outlet water temperature to fail to reach the actual detected temperature, thus affecting the user experience.

[0044] In a possible implementation, at least some of the multiple temperature detection devices 4 are respectively disposed at the top and bottom of the water tank 1. In this way, the multiple temperature detection devices 4 can detect the water temperature at different depths in the water tank 1, and the control device adjusts the heating device 2 according to the water temperature distribution in the depth direction to avoid large temperature differences between the top and bottom of the water tank 1.

[0045] Preferably, the heating device 2 is located at the bottom of the water tank 1, which can heat the water in the water tank 1 from bottom to top. Specifically, the multiple temperature detection devices 4 include a first temperature detection device, a second temperature detection device, and a third temperature detection device. The first temperature detection device is located at the top of the inner cavity of the water tank 1, and the second and third temperature detection devices are spaced apart at the bottom of the water tank 1. The first, second, and third temperature detection devices are electrically connected to the control device. In this way, the water temperature at different positions in the height direction in the water tank 1 can be detected, and the water temperature at different positions in the same plane can also be detected, which is beneficial for accurately detecting and analyzing the water temperature distribution in the water tank 1.

[0046] In a possible implementation, a water level detection device 5 is installed in the water tank 1. The water level detection device 5 is electrically connected to the control device and is used to detect changes in the water level in the water tank 1. It can transmit the water level data to the control device, and the control device can determine whether the heating water tank needs to be filled with water and whether the water level in the water tank 1 meets the heating conditions based on the water level data.

[0047] Specifically, the control device is configured to turn on the heating device 2 when the water level reaches the preset water level, so as to prevent the water tank 1 from drying out due to heating when the water level is too low.

[0048] In a possible implementation, a third detection element is disposed on the side of the second detection element 32 away from the first detection element 31. The second and third detection elements are connected through a water level detection circuit to form a water level detection device 5. The water level detection circuit is electrically connected to a control device and is used to transmit a water level signal to the control device. Thus, by providing a third detection element and connecting it to the second detection element 32 through a water level detection circuit, water level detection can be achieved, simplifying the device structure, while not affecting the detection circuit 3's detection of humidity in the interval area.

[0049] Specifically, the second detection element 32 has a second fixed end and a second detection end, and the third detection element has a third fixed end and a third detection end. The second fixed end and the third fixed end are spaced apart at the top of the water tank 1. The second detection end is at a preset distance from the bottom of the water tank 1, and the distance between the third detection end and the bottom of the water tank 1 is less than the preset distance. Specifically, when the water level in the water tank 1 is lower than the third detection end, both the second and third detection ends in the water level detection circuit are open circuits, and the water level information indicates that the water level in the water tank 1 is low, requiring water filling. When the water level in the water tank 1 is higher than the third detection end but lower than the second detection end, the third detection end is closed and the second detection end is open circuit, and the water level information indicates that the water level in the water tank 1 has reached the preset water level range, meeting the water level requirements for heating. When the water level is higher than the second detection end, both the second and third detection ends are closed circuits, and the water level information indicates that the water level in the water tank 1 exceeds the preset water level range, requiring drainage to meet the water level requirements.

[0050] In a possible implementation, the control device is configured to control the heating device 2 to reduce heating efficiency when the received electrical signal data indicates that the conductivity has reached a first preset value. Reducing heating efficiency during the heating process of the water tank 1 extends the heating time, preventing a rapid increase in local water temperature in the water tank 1 and causing uneven water temperature distribution; and also preventing rapid accumulation of water vapor due to high-efficiency heating, which could affect the accuracy of humidity detection.

[0051] In a possible implementation, the control device is configured to stop heating the heating device 2 when the received electrical signal data indicates that the conductivity has reached a second preset value. Understandably, the second preset value can indicate the conductivity between the first detection element 31 and the second detection element 32 when the water in the water tank 1 reaches a boiling state. The control device can determine whether the water in the water tank 1 has reached a boiling state based on the conductivity indicated by the detection circuit 3, and automatically shut off the heating device 2 when the water boils, thus achieving accurate determination of the boiling point.

[0052] In a possible implementation, the heating device 2 includes a heating plate and an AC controller. The heating plate is located at the bottom of the water tank 1 and is electrically connected to the AC controller. The AC controller is electrically connected to a control device and can control the heating efficiency of the heating device 2 by controlling the voltage.

[0053] In a possible implementation, the heating water tank also includes an inlet pipe 6 and an inlet valve 7. The inlet pipe 6 is connected to the water tank 1 and is used to introduce room temperature water into the water tank 1. The inlet valve 7 is located between the inlet pipe 6 and the water tank 1 and is used to control the connection and disconnection between the inlet pipe 6 and the water tank 1.

[0054] Specifically, the inlet valve 7 is electrically connected to the control device, which is configured to open the inlet valve 7 when the received water level data is lower than the preset water level, and close the inlet valve 7 when the water level data reaches the preset water level. The control device can control the opening and closing of the inlet valve 7 based on the water level information, ensuring timely replenishment of water to the water tank 1, preventing the heating tank from drying out, and preventing excessive water intake from causing boiling water overflow. It is understood that the preset water level is the minimum water level at which heating can be performed.

[0055] In a possible implementation, the heating water tank also includes an exhaust pipe 8 and an exhaust valve 9. The exhaust pipe 8 is connected to the water tank 1 and is used to discharge water vapor in the water tank 1 to prevent excessive air pressure in the water tank 1. The exhaust valve 9 is located between the exhaust pipe 8 and the water tank 1 and is used to control the connection and disconnection between the exhaust pipe 8 and the water tank 1.

[0056] Specifically, the exhaust valve 9 is electrically connected to the control device, which is configured to open the exhaust valve 9 when the heating device 2 stops heating, so that the exhaust pipe 8 is connected to the water tank 1. This allows water vapor in the water tank 1 to be discharged through the exhaust pipe 8 when the water in the water tank 1 reaches boiling point and when the heating device 2 stops heating, thus preventing excessive pressure in the water tank 1 from causing an explosion or rupture of the water tank 1.

[0057] Specifically, the control device is configured to close the exhaust valve 9 when the heating device 2 is turned on, thereby disconnecting the exhaust pipe 8 from the water tank 1. This prevents water vapor from affecting the accuracy of the detection circuit 3 during the heating process of the water in the water tank 1.

[0058] In a possible implementation, the heating water tank also includes a water outlet, which is connected to the water tank 1. Preferably, the water outlet is located near the bottom of the water tank 1 for easy access by the user. A water outlet valve is provided between the water outlet and the water tank 1, and the water outlet valve is electrically connected to the control device.

[0059] Please refer to Figure 2 The diagram illustrates a flow chart of a control method for a heated water tank according to an embodiment of this application. This specification provides the method operation steps as shown in the embodiments, but based on conventional or non-inventive labor, more or fewer operation steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many steps and does not represent the only possible execution order. In actual preparation method execution, the method can be executed in the order shown in the embodiments or the accompanying drawings, or in parallel. The following, in conjunction with... Figure 2 This application introduces a control method provided by an embodiment of the invention. The control method is applied to a heating water tank and includes steps S100-S200:

[0060] S100: When the heating device 2 is in a heating state, acquire the electrical signal data of the detection circuit 3. The electrical signal data is used to indicate the conductivity between the first detection element 31 and the second detection element 32.

[0061] S200: If the conductivity indicated by the electrical signal data reaches the second preset value, control the heating device 2 to shut down.

[0062] Understandably, the second preset value can be indicated as the conductivity between the first detection element 31 and the second detection element 32 when the water in the water tank 1 reaches the boiling state; the control device can determine whether the water in the water tank 1 has reached the boiling state according to the conductivity indicated by the detection circuit 3, and automatically turn off the heating device 2 when the water boils, thus achieving accurate determination of the boiling point.

[0064] S300: If the conductivity indicated by the electrical signal data reaches the first preset value, control the heating device 2 to reduce the heating efficiency.

[0065] Specifically, if the first preset value is less than the second preset value, it can be understood that when the water in the water tank 1 has not reached the boiling state, the heating efficiency of the heating device 2 is reduced, the heating time is extended, and the movement time of water molecules is extended, thereby improving the uniformity of water temperature distribution.

[0066] In possible implementations, the control method further includes:

[0068] S400: If the temperature difference between multiple temperature data is less than or equal to the preset temperature difference, and the conductivity indicated by the electrical signal data reaches the second preset value, control the heating device 2 to shut down.

[0075] In possible implementations, the control method further includes:

[0076] S900: After the heating device 2 is turned off, control the exhaust valve 9 to open.

[0077] The following combination Figure 3 In introducing a control method in an application scenario, it should be understood that, although Figure 3 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 3 At least some of the steps in the process may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the steps or stages in other steps.
