Description

Technical Field

[0001] This invention relates to the technical field of water pump output, specifically to a method for controlling the smooth water output of a water heating device and its tea extractor. Background Technology

[0002] This tea infuser includes a heating container (i.e., a teapot) for holding liquid, which uses an inlet pump to draw cold, potable bottled water into the teapot. Once the liquid in the heating container is heated to boiling, a outlet pump delivers the hot water to the cup. However, the high temperature and the large amount of steam in boiling liquid can affect the smoothness of the water flow from the outlet pump. Therefore, further improvements are needed. Summary of the Invention

[0003] This invention proposes a method for controlling the smooth water output of a water heating device and its tea extractor, which mainly solves the technical problem of uneven water output caused by the water pump directly drawing the boiling liquid after the liquid in the heating container is heated to boiling.

[0004] A method for controlling the smooth water flow of a water heating device designed for this purpose includes the following steps:

[0005] The water heating device heats the liquid in the heating container to a boiling point;

[0006] Before starting the water pump of the water heating device to output water, start the water inlet structure of the water heating device and add cold water into the heating container to reduce the temperature of the liquid in the heating container.

[0007] After the temperature of the liquid in the heating container decreases, the impact on the operation of the water outlet pump of the water heating device is reduced. The water outlet pump of the water heating device is then started to output water, so as to achieve smooth water output from the water heating device.

[0008] The water inlet structure of the water heating device includes an inlet pump, which starts at different times and does not work simultaneously. During the cooling and water replenishment process, the start and stop of the inlet pump is controlled manually or automatically by a program.

[0009] During the process of adding cold water to the heating container in step two, a detection threshold is set, and the water pump stops running when the detection value reaches the preset detection threshold.

[0010] The detection values ​​are one or more combinations of liquid temperature, liquid position height, continuous water replenishment duration, or cumulative water inflow.

[0011] During the process of adding cold water to the heating container in step two, the temperature of the liquid inside the heating container is detected by a temperature sensor. When the temperature of the liquid inside the heating container drops to a preset temperature threshold, the water inlet pump stops running.

[0012] Alternatively, during the process of adding cold water to the heating container in step two, the liquid level in the heating container is detected by a water level sensor. When the liquid level in the heating container reaches the detection threshold, the water pump stops running.

[0013] During the process of adding cold water to the heating container in step two, the duration of continuous water replenishment by the water inlet pump is detected by a timer. When the duration of continuous water replenishment by the water inlet pump reaches a preset time threshold, the water inlet pump stops running.

[0014] During the process of adding cold water to the heating container in step two, the inlet water flow rate is monitored in real time by a flow meter; when the cumulative inlet water flow rate reaches the preset flow rate threshold, the inlet water pump stops running.

[0015] During the process of adding cold water to the heating container in step two, the cumulative replenishment volume of the water inlet pump is monitored in real time by a flow meter, or the continuous replenishment duration of the water inlet pump is monitored in real time by a timer; when the monitored cumulative replenishment volume or continuous replenishment duration is lower than a preset lower threshold or higher than a preset upper threshold, the alarm device is controlled to issue an alarm by sound and / or light.

[0016] A tea extractor using the smooth water outlet control method of the water heating device described above includes a base with a water outlet, a heating container detachably mounted on the base, a water pump installed inside the base, the output end of the water pump being connected to the water outlet through a pipe, and the input end of the water pump being connected to the water outlet of the heating container.

[0017] The base is also equipped with a water inlet pump for replenishing cold water to the heating container. The output end of the water inlet pump is connected to the water inlet of the heating container through a pipe, and the input end of the water inlet pump is connected to a water supply device.

[0018] An electrical coupling structure is provided between the base and the heating container, and a heating element is provided at the bottom of the heating container.

[0019] The electrical coupling structure includes a first coupler disposed on the bottom of the heating container and a second coupler disposed on the base. A water channel insertion coupling part is provided between the first coupler and the second coupler. The water channel insertion coupling part includes a water channel disposed on the first coupler and a plug-in end disposed on the second coupler. The water inlet and outlet of the heating container are disposed on the same water channel. A spring and a ball valve are disposed on the water channel, and a push rod is disposed on the plug-in end. When the heating container is installed on the base, the push rod pushes open the ball valve to open the water channel.

[0020] When water is introduced, the water inlet pump starts, and the liquid enters the heating container through the water inlet pump and water passage.

[0021] When water is discharged, the discharge pump starts, and the liquid is output to the target location through the water passage and the discharge pump.

[0022] The beneficial technical effects of the present invention are as follows:

[0023] By adding cold water to the heating container after the liquid in the heating container has been heated to boiling and before starting the water pump, the temperature of the boiling liquid is reduced. This avoids the problem of uneven water flow caused by the boiling hot water directly entering the water pump, ensuring smooth water flow after the water pump is started. This solves the technical problem of uneven water flow caused by directly sucking boiling liquid in the prior art. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In order to make the above-mentioned objects, features and advantages of this application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] See Figures 1-5 A method for controlling the smooth water flow of a water heating device includes the following steps:

[0031] (a) The water heating device heats the liquid in the heating container 1 to a boiling state;

[0032] (ii) Before starting the water pump 2 of the water heating device to output water, start the water inlet structure of the water heating device and add cold water into the heating container 1 to reduce the temperature of the liquid in the heating container 1;

[0033] (iii) After the temperature of the liquid in the heating container 1 decreases, the impact on the operation of the water outlet pump 2 of the water heating device is reduced. The water outlet pump 2 of the water heating device is started to output water, so as to realize the smooth water output of the water heating device.

[0034] By adding cold water to the heating container 1 after the liquid in the heating container 1 has been heated to boiling and before the water pump 2 is started, the temperature of the boiling liquid is reduced. This avoids the phenomenon of uneven water flow caused by the boiling hot water directly entering the water pump, and ensures smooth water flow after the water pump 2 is started. This solves the technical problem of uneven water flow caused by directly sucking boiling liquid in the prior art.

[0035] The water inlet structure of the water heating device includes an inlet pump 3, which starts at the same time as the outlet pump 2, and the two do not work at the same time. In the cooling and water replenishment process, the start and stop of the inlet pump 3 is controlled manually or automatically by the program.

[0036] The program automatically controls the start and stop of the inlet pump 3, improving the user experience. By setting the inlet and outlet pumps to start at different times and not operate simultaneously, the independence and stability of the water replenishment and outlet processes are ensured, which simplifies system control and improves operational reliability.

[0037] During the process of adding cold water to the heating container 1 in step two, the water inlet pump 3 stops running when the detection value reaches the preset detection threshold by setting a detection threshold.

[0038] By setting a detection threshold, the water pump 3 will automatically stop running when the detection value reaches the preset threshold, thus realizing the automated control of the cooling and water replenishment process, avoiding excessive or insufficient water replenishment, and improving the control accuracy of water replenishment.

[0039] The detection values ​​are one or more combinations of liquid temperature, liquid position height, continuous water replenishment duration, or cumulative water inflow.

[0040] By setting the detection threshold to one or more combinations of liquid temperature, liquid position height, continuous water replenishment duration, or cumulative water inflow, a variety of control parameters are available, making it easy to flexibly configure the control logic of the cooling and water replenishment process according to different application scenarios and accuracy requirements.

[0041] During the process of adding cold water to the heating container 1 in step two, the temperature of the liquid in the heating container 1 is detected by a temperature sensor. When the temperature of the liquid in the heating container 1 drops to a preset temperature threshold, the water pump 3 stops running; for example, the preset temperature threshold is set to 80 degrees Celsius or 85 degrees Celsius.

[0042] Alternatively, during the process of adding cold water to the heating container 1 in step two, the liquid level in the heating container 1 is detected by a water level sensor. When the liquid level in the heating container 1 reaches the detection threshold, the water inlet pump 3 stops operating. The water level sensor is set at the high water level position.

[0043] The water pump can be stopped by using a temperature sensor or a water level sensor: a temperature sensor can automatically stop water replenishment when the liquid temperature drops to a preset threshold, directly ensuring the cooling effect; a water level sensor can stop water replenishment when the liquid level reaches a detection threshold, effectively preventing the heating container from overflowing due to excessive water replenishment, thus improving safety.

[0044] During the process of adding cold water to the heating container 1 in step two, the duration of continuous water replenishment by the water inlet pump 3 is detected by a timer. When the duration of continuous water replenishment by the water inlet pump 3 reaches a preset time threshold, the water inlet pump 3 stops running.

[0045] The system uses a timer to monitor the continuous water supply duration of the inlet pump. Water supply automatically stops when a preset time threshold is reached. This control method is simple and low-cost, requiring no additional temperature or water level sensors to achieve basic water supply control. The continuous water supply duration can be set to 30 seconds or more.

[0046] During the process of adding cold water to the heating container 1 in step two, the inlet water flow rate is monitored in real time by a flow meter; when the monitored cumulative inlet water flow rate reaches the preset flow rate threshold, the inlet water pump 3 stops running.

[0047] The system monitors the cumulative influent flow rate in real time using a flow meter. When the preset flow threshold is reached, the influent pump automatically stops, precisely controlling the water supply. This prevents insufficient water supply leading to inadequate cooling or excessive water supply causing overflow, thus improving the accuracy and reliability of water supply control. The preset flow threshold is 100ml.

[0048] During the process of adding cold water to the heating container 1 in step two, the cumulative replenishment volume of the water inlet pump 3 is monitored in real time by a flow meter, or the continuous replenishment duration of the water inlet pump 3 is monitored in real time by a timer; when the monitored cumulative replenishment volume or continuous replenishment duration is lower than the preset lower threshold or higher than the preset upper threshold, the alarm device is controlled to issue an alarm in the form of sound and / or light.

[0049] The cumulative replenishment volume or continuous water replenishment duration is monitored in real time by a flow meter or timer, and upper and lower limit thresholds are set. When the monitored value exceeds the normal range, the alarm device is triggered to issue an alarm in the form of sound and / or light. This can promptly remind the user of abnormalities in the water replenishment process (such as insufficient water supply, pipeline blockage, or equipment failure), making it easier for the user to stop the machine in time to troubleshoot the problem, thus improving the safety of the equipment and the diagnosability of the fault.

[0050] A tea extractor using the above-described water heating device and smooth water output control method includes a base 4 with a water outlet, a heating container 1 detachably mounted on the base 4, a water pump 2 mounted inside the base 4, the output end of the water pump 2 connected to the water outlet through a pipe, and the input end of the water pump 2 connected to the water outlet of the heating container 1.

[0051] The base 4 is also equipped with a water inlet pump 3 for replenishing cold water to the heating container 1. The output end of the water inlet pump 3 is connected to the water inlet of the heating container 1 through a pipe, and the input end of the water inlet pump 3 is connected to a water supply device.

[0052] An electrical coupling structure is provided between the base 4 and the heating container 1, and a heating element 5 is provided at the bottom of the heating container 1.

[0053] The electrical coupling structure includes a first coupler disposed on the bottom of the heating container 1 and a second coupler disposed on the base 4. A water channel insertion coupling part is provided between the first coupler and the second coupler. The water channel insertion coupling part includes a water channel 6 disposed on the first coupler and a plug-in end disposed on the second coupler. The water inlet and water outlet of the heating container 1 are disposed on the same water channel 6. A spring 7 and a ball valve 8 are disposed on the water channel 6, and a push rod 9 is disposed on the plug-in end. When the heating container 1 is installed on the base 4, the push rod 9 pushes open the ball valve 8 to open the water channel 6.

[0054] When water is introduced, the water inlet pump 3 starts, and the liquid enters the heating container 1 through the water inlet pump 3 and the water passage 6;

[0055] When water is discharged, the water pump 2 starts, and the liquid is output to the target position through the water channel 6 and the water pump 2.

[0056] The inlet pump 3 and the outlet pump 2 are pressure unidirectional water pumps; the liquid can only flow in one direction, and a certain water pressure is required for water to flow, that is, the water pump can only flow when it is started.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
