[0080] The upper end of the independent water flow pipe 4 can be arranged at the spout 2 or the pot cover opening 301 or the pot wall through hole on the pot wall, or the upper end of the independent water flow pipe 4 extends out of the spout 2 or the pot cover opening 301 or the pot wall through hole on the pot wall. The independent water flow pipe 4 can be fixed or pluggable.

[0081] Furthermore, the independent water flow pipe 4 can be manually plugged in or automatically plugged in. Manual plugging in and out means manually placing the independent water flow pipe 4 inside the kettle body 1 or taking it out from the kettle body 1 .

[0082] Specific implementation of the decoction method: The heating device is an electromagnetic heating device or an electric ceramic heater, located inside the base of the kettle. The temperature is controlled electronically, including the ability to heat on high or low heat, or at intervals. The kettle body can be equipped with a temperature sensor; the water supply or withdrawal time is automatically set according to the water supply or withdrawal amount; the water storage box 7 has a capacity of 4 liters and is actually filled with 4 liters of water, while the collection box 6 has a capacity of 1 liter and is empty. The working process is shown in Figure 2: the spout 2 is connected to the water inlet and outlet 501 of the base through an external water pipe 12, and the lower end of the spout 2 is located inside the kettle body and communicates with the inside of the kettle body; put an appropriate amount of Chinese medicine into the kettle body, press the decoction function key on the control panel after turning on the machine, and then press the preset time of 5 hours; after 5 hours, the control device automatically starts the water supply pump 9 to supply water from the water storage box 7 to the inside of the kettle body 1, and the water flows into the inside of the kettle body 1 through the water storage box 7, the water supply pump 9, the three-way device 10, the base water inlet and outlet 501, the external water pipe 12 and the spout 2. The control panel measures the water supply time, and the water supply is stopped when the set water supply time of 120 seconds is reached. The expected water supply is 1.5 liters. After soaking the medicine at room temperature for 30 minutes, start the heating device for the first time to heat it at high heat for boiling. Stop heating after starting interval heating for 25 minutes, then start the water pump 8 to collect liquid to the collection box 6, and the medicine juice inside the kettle body flows into the collection box 6 through the spout 2, the external water pipe 12, the water inlet and outlet 501 of the base, the three-way device 10 and the water pump in turn. Stop collecting when the pumping time is 40 seconds; start the second time to add water to the inside of the kettle body 1 for 90 seconds, then stop adding water, and it is expected to supply 1.1 liters of water. Start the heating device for the second time to heat it at high heat. After the heating device heats it to boiling, keep heating it at high heat for 1 minute and then stop heating. Then the heating device heats it at low heat and stops heating after 13 minutes. The second heating is completed, and the buzzer prompts 3 times that the decoction is complete.

[0083] In addition, the heating method of placing the kettle body 1 on the kettle base 5, including electromagnetic heating or electric ceramic heating method and the water inlet and outlet method of the kettle without a spout, is also suitable for a split-type water-adding electric cooker or other heating containers, except that the pot is larger in volume than the kettle, because the split-type water-adding electric cooker includes a pot body and a pot base, the pot body is equal to the kettle body, and the pot base is equal to the kettle base, the pot body includes a pot wall and a pot cover, and an independent water flow pipe can be inserted into the inside of the pot cover opening or the inside of the pot wall opening to supply or pump water. Its working principle is the same as that of the automatic liquid inlet and outlet multifunctional kettle, so it can be extended from the automatic liquid inlet and outlet multifunctional kettle to similar related products.

The external water source device 13 can be a large bucket, water tank, or other container, or the water source connecting pipe can be directly connected to tap water. It should be noted that when the water source connecting pipe is directly connected to tap water, the water supply pump 9 can be replaced with a water supply valve; the other end of the water supply line is connected to the first interface of the three-way device 10. It can be seen that the water source of this embodiment is an external water source. Moreover, another embodiment can be further inferred from the first embodiment, that is, the water storage box 7 is not changed, and the external collection device 14 is set externally.

[0087] The working process is shown in Figure 4: manually set the menu and preset working time on the control panel, and the water supply pump 9 is automatically started to supply water to the inside of the kettle body 1 after the preset time.

The three-way device 10 is a three-way valve. The external water source device 13 and the external collection device 14 are placed independently.

[0091] The operating process is shown in Figure 6: an independent water pipe 4 is positioned within the spout 2, the lower end of which is positioned within the kettle body 1. The upper end of the independent water pipe 4 is directly connected to the base water inlet and outlet 501 via an external water pipe 12. The base water inlet 502 is connected to tap water, a water supply valve is provided, and the base water outlet 503 is connected to an external collection device 14.

[0092] Example 4:

[0093] As shown in Figures 7 and 8, this embodiment provides a multifunctional kettle with automatic liquid inlet and outlet, which uses an auxiliary device 15 and a kettle body. The kettle body includes a kettle body 1 and a kettle base 5. The kettle body 1 can be placed on the kettle base 5. The kettle base 5 or the bottom of the kettle body 1 is provided with a heating device. When the kettle body 1 is placed on the kettle base 5, the kettle body 1 can be heated. The kettle base 5 is fixed on the auxiliary device 15. One or more of the following devices can be set inside the auxiliary device 15, including a collection box 6, a water storage box 7, a water pump 8, a water supply pump 9 (or a water supply valve), a three-way device 10, a power supply device, and a control device, and an auxiliary water inlet and outlet 161 is provided on the auxiliary device 15.

[0094] Among them, the kettle base 5 is fixed to one side of the auxiliary device 15, and the two are an integrated structure, wherein the power supply device and the control device can be fixed in the kettle base 5 or the auxiliary device 15. In this embodiment, the control device is a control panel, and the control panel is fixed on the kettle base 5. The power supply device is connected to the mains, and the power supply device provides power to related electrical components.

[0095] The kettle body 1 can be connected to the auxiliary water inlet and outlet 161 of the auxiliary device 15 through the spout 2 or the independent water flow pipe 4. Specifically, the spout 2 and the auxiliary water inlet and outlet 161 can be directly connected; or the spout 2 and the auxiliary water inlet and outlet 161 can be connected through the external water pipe 12; or the upper end of the spout 2 and the auxiliary water inlet and outlet 161 are respectively provided with auxiliary water pipe joints 17, and the auxiliary water pipe joint 17 at the upper end of the spout 2 can be connected to the auxiliary water pipe joint 17 of the auxiliary water inlet and outlet 161; or the upper end of the spout 2 and one end of the external water pipe 12 are respectively provided with auxiliary water pipe joints 17, and the auxiliary water pipe joint 17 at the upper end of the spout 2 can be connected to the auxiliary water pipe joint 17 at one end of the external water pipe 12, and the other end of the external water pipe 12 is connected to the auxiliary water inlet and outlet 161. The upper end of the independent water pipe 4 and the auxiliary water inlet and outlet 161 are directly connected; or, the independent water pipe 4 and the auxiliary water inlet and outlet 161 are connected through an external water pipe 12; or, auxiliary water pipe joints 17 are respectively provided at the upper end of the independent water pipe 4 and the auxiliary water inlet and outlet 161, and the auxiliary water pipe joint 17 at the upper end of the independent water pipe 4 can be connected to the auxiliary water pipe joint 17 of the auxiliary water inlet and outlet 161; or auxiliary water pipe joints 17 are respectively provided at the upper end of the independent water pipe 4 and one end of the external water pipe 12, and the auxiliary water pipe joint 17 at the upper end of the independent water pipe 4 can be connected to the auxiliary water pipe joint 17 at one end of the external water pipe 12, and the other end of the external water pipe 12 is connected to the auxiliary water inlet and outlet 161; or the upper end of the independent water pipe 4 is connected to one end of the external water pipe 12, and an auxiliary water pipe joint 17 is provided at the other end of the external water pipe 12 to be connected to the auxiliary water inlet and outlet 161.

The independent water pipe 4 passes through a through hole in the kettle wall of the kettle body 1. Furthermore, the water inlet or connector can also be a direct plug-in quick connector.

[0096] Furthermore, for the convenience of operation, the auxiliary water inlet and outlet 161 can be elastically extended and retracted, and the periphery of the auxiliary water inlet and outlet 161 is connected to the auxiliary device 15 through a spring; when the upper end of the spout 2 or the independent water flow pipe 4 contacts the auxiliary water inlet and outlet 161, the spring drives the auxiliary water inlet and outlet 161 to retract inward, and after the two are connected, the spring drives the auxiliary water inlet and outlet 161 to extend outward, which can better connect the water outlet.

[0097] On this basis, another embodiment can be further expanded. Instead of setting the collection box 6, a water inlet and a water inlet switch can be set on the auxiliary device 15. The liquid from the inside of the kettle body passes through the water pump 8 and flows out from the water inlet after passing through the water inlet switch. A water receiving cup is placed at the water inlet.

The water supply flow sensor sends the amount of water to be added to the control device. When the set water supply amount is reached, the water supply is stopped, and the heating device is started to heat the kettle body. The heating automatically stops after the program-set heating time is reached. A water cup is placed under the water inlet. When the water cup touches the water inlet switch, the water pump 8 is started. The water inside the kettle body flows into the water cup through the independent water flow pipe 4, the external water pipe, the auxiliary water inlet and outlet 161, the three-way device 10, the water pump 8, the water inlet switch, and the water inlet. The above process can be repeated, and a completion prompt is issued after all the procedures are completed.

The kettle body includes a kettle body 1 and a kettle base 5, and the bottom of the kettle body 1 is provided with a kettle bottom structure 18. The kettle body 1 does not have a spout 2. Similarly, the kettle body 1 of other embodiments can also be adjusted to have no spout 2. The above-mentioned liquid communication through the spout 2 can be completely replaced by an independent water pipe 4 passing through the pot cover through hole 301 or the pot wall through hole. Various methods can be replaced with each other and flexibly set.

[0101] The kettle body 1 and the kettle base 5 are provided with corresponding hydroelectric couplers 19, and the hydroelectric couplers 19 include a water interface and an electrical interface. The hydroelectric coupler 19 connected to the bottom of the kettle body 1 is an upper hydroelectric coupler 1901, and the coupler connected to the kettle base 5 is a lower hydroelectric coupler 1902. The lower hydroelectric coupler 1902 on the kettle base 5 is docked with the upper hydroelectric coupler 1901 on the kettle body 1 to achieve water and electricity connection. In order to connect the water inside the kettle body 1 with the water interface of the hydroelectric coupler 19, a kettle wall water pipe 20 is required. The kettle wall water pipe 20 has multiple connection methods with the kettle body 1. The kettle wall water pipe 20 passes through the kettle wall through-hole at the lower end, and one end of the kettle wall water pipe 20 is connected to the water interface in the hydroelectric coupler 19 on the kettle body 1, and the other end of the kettle wall water pipe 20 is connected to the inner end of the kettle wall through-hole; or, the kettle wall water pipe 20 passes through the waterless through-hole above the kettle body 1, and one end of the kettle wall water pipe 20 is connected to the kettle The kettle wall water pipe 20 is connected to the water interface in the hydroelectric coupler 19 on the kettle body 1, and the other end of the kettle wall water pipe 20 passes through the water-free hole above the kettle body 1 and extends into the interior of the kettle body. Specifically, the kettle wall water pipe 20 can extend above the bottom of the kettle body; or, the kettle wall water pipe 20 passes through the upper port on the kettle body, one end of the kettle wall water pipe 20 is connected to the water interface in the hydroelectric coupler 19 on the kettle body 1, and the other end of the kettle wall water pipe 20 passes through the upper port on the kettle body and extends into the interior of the kettle body, specifically, it can extend above the bottom of the kettle body.

[0102] The water connection on the lower water electrical coupler 1902 on the kettle base 5 is connected to the first connection of the three-way valve. The second connection of the three-way valve is connected to the external water source device 13 through the water supply device and the base water inlet 502. The third connection of the three-way valve is connected to the collection box 6 through the pumping device. The collection box 6 is arranged inside, on the side of, or on the kettle base 5. The kettle base 5 also includes a pumping pipeline, a water pump 8, a water supply pipeline, and a water supply pump 9. Here, the water pump 8 and the water supply pump 9 both have their own water valves. The three-way valve is an electrically controlled three-way valve. The specific connection relationship is not detailed here.

[0103] When a through hole or a bottom opening is provided at the lower end of the kettle wall, one end of the kettle wall water pipe 20 is connected to the water interface in the upper water-electric coupler 1901 on the kettle body 1, and the other end of the kettle wall water pipe 20 is connected to one end of the kettle body water valve, and the other end of the kettle body water valve is connected to the inner end of the lower kettle wall through hole or the bottom opening.

When water needs to be supplied or pumped into the kettle body 1, the control device supplies power to the kettle body water valve, and the kettle body water valve opens. When the water supply or pumping is completed, the control device de-energizes the kettle body water valve, and the kettle body water valve closes. It should be noted that the other two connection methods between the kettle wall water pipe 20 and the kettle body 1 do not require a kettle body water valve.

[0104] In addition, a power supply device is provided on the base 5 of the kettle, an electric heating plate is provided under the bottom structure 18 of the kettle, and the bottom of the kettle body 1 is made of metal. After the electrical interface on the lower water-electric coupler 1902 on the kettle base 5 is connected with the electrical interface on the upper water-electric coupler 1901 on the kettle body 1, the power supply device can supply power to the electric heating plate.

[0105] In actual use, a menu and preset operating time are manually set. When the preset time expires, the water supply pump 9 automatically starts.

In order to distinguish them from the water supply pipeline or the water extraction pipeline already in the original embodiment, the water supply pipeline or the water extraction pipeline added on the basis of other embodiments is called an additional water supply pipeline or an additional water extraction pipeline. It should be noted that the water supply pipeline or the water extraction pipeline already in the original embodiment are all called water supply pipelines or water extraction pipelines. When two water supply pipelines are set in the kettle body at the same time, any one of them is called water supply pipeline A and the other is called water supply pipeline B. Alternatively, when two water extraction pipelines are set at the same time, any one of them is called water extraction pipeline A and the other is called water extraction pipeline B to distinguish them.

[0113] The following selectively describes the workflow in conjunction with all the above figures;

[0114] Among them, the additional external water source device and the additional external collection device have working processes, the additional external water source device automatically supplies water to the inside of the kettle body 1, and automatically pumps water from the inside of the kettle body 1 to the additional external collection device, and the corresponding working methods include cooking or brewing or making or soaking.

[0115] In the specific implementation of the sea cucumber soaking method, FIG13 shows an external water source device 13 placed inside an external collection device 14. Of course, the external collection device 14 shown in FIG14 can also be placed inside the external water source device 13. The two functions are the same. A kettle body temperature sensor is provided. The water supply pipeline is provided with a water supply flow sensor 11, a water supply pump 9, and an external water source device 13. The water extraction pipeline is provided with a water extraction pump 8, a water extraction flow sensor, and an external collection device 14.

The commonly used pure water barrel can be placed inside the empty water barrel of the collection container.

[0116] 50 grams of dried sea cucumber to be soaked is placed into the kettle body 1. A control panel is provided on the auxiliary device 15. The machine is turned on and the sea cucumber soaking function button on the control panel is pressed to initiate soaking. The control panel issues a soaking command and the water supply is first activated. 1.3 liters of water are added to the kettle body 1. When 1.3 liters are added, the water flow sensor 11 signals a completion signal, and the water supply pump 9 stops supplying water, stopping the water supply from the water supply barrel. The soaking phase then begins. The heating device is activated to heat the water inside the kettle body 1 until the temperature reaches the set temperature of 48 degrees Celsius. When the temperature drops to 40 degrees Celsius, the heating device is activated intermittently, maintaining the temperature within the kettle body 1 within a set range of 40 to 48 degrees Celsius. The sea cucumber is soaked for 12 hours. After the set soaking time of 12 hours, water is pumped from the kettle body 1 through the pumping pipe to the external collection device 14. When the set amount of water is reached, the pumping flow sensor signals a stop, completing the first soaking phase. Then, the water supply is started for the second time and 1.4 liters of water is added to the water barrel. After the water supply is completed, the water supply is stopped and the heating device is started until the water temperature inside the kettle body 1 reaches the set temperature of 48 degrees and then the heating is stopped. When the temperature drops to 40 degrees, the heating device is started to heat and maintain the temperature between 40 and 48 degrees. After 12 hours of soaking, the water is pumped out and the water inside the kettle body 1 is pumped into the collection bucket through the pumping pipe. When the set pumping volume is reached, the pumping flow sensor sends a signal to pump water, and the second soaking is completed. Then, the water supply is started for the third time and 2 liters of water are added before stopping. The constant temperature is controlled for 12 hours as above, and the constant temperature brewing stage is over. Then, the brewing stage begins. The heating device is started for the first time to heat the water inside the kettle body 1 until it boils and then the heating is stopped. After simmering for 20 minutes, the water is pumped out and can be pumped out completely. The water supply is started for the fourth time and then 2 liters of water are added to the water barrel and then stopped. The first brewing is over. Twenty hours later, the heating device is activated a second time to heat the water inside the kettle body 1 until it boils, then stops heating. After 20 minutes of simmering, the control device issues a pumping command, and the water inside the kettle body 1 is pumped through the pumping pipe into the collection bucket. As the water volume in the water supply bucket decreases and the water level in the collection bucket continues to rise, the water in the water supply bucket gradually floats upward due to buoyancy. When the set water volume is reached, the pumping flow sensor issues a signal to stop pumping, completing the second brewing phase. The subsequent brewing phase then begins. The water supply bucket is activated a fifth time, adding 1.8 liters of water for room-temperature soaking. Eight hours later, pumping is resumed, concluding the first room-temperature soaking phase. The seventh water supply is activated a seventh time, supplying 1.8 liters of water, and eight hours later, pumping is resumed, concluding the second room-temperature soaking phase.
