[0024] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0025] Example 1

[0026] refer to Figure 1This embodiment provides a water system for a tea bar machine, including a heating module, a water supply module, and a control module. The heating module includes a hot pot assembly and an electric kettle assembly. A cold water inlet is provided at the bottom or lower end of the side wall of the hot pot assembly, a hot water outlet is provided at the top or upper end of the side wall of the hot pot assembly, and a water filling port is provided at the top of the electric kettle assembly. The hot pot assembly is used to heat the water therein and provide the user with hot water for immediate use, while the electric kettle assembly is used to heat the water therein, so that the tea bar machine has two heating methods. The water supply module includes a water inlet assembly and a water outlet assembly. The water inlet assembly is respectively connected to the cold water inlet of the hot pot assembly and the water filling port of the electric kettle assembly to provide the required water to the hot pot assembly and the electric kettle assembly at the same time. The water outlet assembly is connected to the hot water outlet of the hot pot assembly to provide the user with instant hot water.

[0027] The control module is electrically connected to the hot pot assembly, the electric kettle assembly, the water inlet assembly, and the water outlet assembly, respectively. The control module is configured to determine a target flow rate for the water inlet assembly based on the water inlet temperature of the water inlet assembly, the hot water temperature within the hot pot assembly, and the water outlet temperature of the water outlet assembly, and further configured to control the actual flow rate of the water inlet assembly based on the target flow rate. Specifically, the control module is configured to determine a target flow rate for the first water pump 321 in the water inlet assembly based on the water inlet temperature sensor 34 in the water inlet assembly, the hot water sensor 13 in the hot pot assembly, and the water outlet temperature sensor 42 in the water outlet assembly, and further configured to control the current flow rate of the first water pump 321 in the water inlet assembly based on the target flow rate.

[0028] refer to Figure 1 Furthermore, the hot tank assembly includes a hot tank body 11, a heating pipe 12, and a hot water sensor 13. In this embodiment, a cold water inlet is provided at the bottom of the hot tank body 11, and a hot water outlet is provided at the top of the hot tank body 11. The heating pipe 12 is disposed within the hot tank body 11 and electrically connected to the control module, and is used to heat the water within the hot tank body 11. The hot water sensor 13 is disposed within the hot tank body 11 and electrically connected to the control module, and is used to detect the temperature of the hot water within the hot tank body 11. The control module is used to control the operating state of the heating pipe 12 based on the hot water temperature detected by the hot water sensor 13.

[0029] In this embodiment, a hot water sensor 13 is mounted on the top of the hot pot body 11 to detect the water temperature near the top of the hot pot body 11. The heating pipe 12 includes a first vertical section 121, a bent section 122, and a second vertical section 123. The bent section 122 is disposed within the hot pot body 11, and the top of the bent section 122 is arranged near the hot water sensor 13. The first vertical section 121 is vertically disposed at the bottom of the bent section 122, and its upper end is connected to the lower end of the bent section 122. The second vertical section 123 is disposed outside the bent section, and its upper end is connected to the upper end of the bent section 122. This allows the heating pipe 12 to occupy a larger area within the hot pot body 11, thereby improving the heating effect.

[0030] Furthermore, the hot tank assembly further includes at least one hot tank thermostat 14. In this embodiment, there are two hot tank thermostats 14, each of which is disposed on opposite side walls of the upper end of the hot tank thermostat 14 and electrically connected to the control module. Thus, in extreme cases, when there is no water inside the hot tank body 11, the hot water sensor 13 senses a certain temperature within a few seconds and immediately cuts off the power, causing the heating tube 12 to stop working. When the hot water sensor 13 fails, the hot tank thermostat 14 (automatic reset) senses a certain temperature and immediately cuts off the power. When both the hot water sensor 13 and the hot tank thermostat 14 fail, the hot tank thermostat 14 (manual reset) senses a certain temperature and immediately cuts off the power. To resume operation, the entire machine must be disconnected from the water and electricity, disassembled, and the disconnected spring clips of the hot tank thermostat 14 restored to their original state.

[0031] refer to Figure 1 Furthermore, the electric kettle assembly includes a kettle body 21 with a water inlet, a heating tube 23, and a temperature sensor 22. The heating tube 23 is disposed at the bottom of the kettle body 21 and is electrically connected to the control module for heating the water in the kettle body 21. The temperature sensor 22 is disposed on the kettle body 21 and is electrically connected to the control module for detecting the temperature of the water in the kettle body 21. In this embodiment, the electric kettle assembly also includes a kettle thermostat 24, which is disposed at the bottom of the kettle body 21 and is electrically connected to the control module. In this way, if the temperature sensor 22 is damaged and the electric kettle assembly boils dry, the kettle thermostat 24 will be disconnected, so that the heating tube 23 will no longer heat, thereby achieving the anti-dry boil function.

[0032] Furthermore, the electric kettle assembly also includes a water level sensor 25 and / or a timer (not shown). The water level sensor 25 is provided on the kettle body 21 and is electrically connected to the control module for detecting the water level in the kettle body 21. The control module is configured to control the operating state of the heating tube 23 based on the water level information. The timer is electrically connected to the control module for recording the duration of water filling the kettle body 21 and / or the duration of heating the heating tube 23.

[0033] In this embodiment, the water level sensor 25 includes a lower water level probe 252 and an upper water level probe 251. The lower water level probe 252 is used to detect the low water level of the kettle body 21, and the upper water level probe 251 is used to detect the high water level of the kettle body 21. Therefore, when the electric kettle assembly needs to obtain water, after pressing the corresponding button, the electric kettle assembly will detect whether the water level in the electric kettle assembly has reached the lower water level probe 252. If the lower water level probe 252 has sensed it, the heating tube 23 will start heating. After the temperature sensor 22 detects that the water temperature has reached the set temperature, it will control the heating tube 23 to stop heating. If the lower water level probe 252 does not sense the presence of water, water addition will be started first, and the water inlet assembly will inject water into the kettle body 21 of the electric kettle assembly. When the upper water level probe 251 senses the presence of water, water addition will stop and the heating function of the electric kettle assembly will be started at the same time.

[0034] In other embodiments, the upper water level probe 251 can be omitted. In this case, if the lower water level probe 252 does not sense the presence of water, water addition will be initiated first. The water inlet assembly will inject water into the kettle body 21 of the electric kettle assembly. When the timer records that the water filling time of the kettle body 21 has reached the set filling time, water addition will be stopped and the heating function of the electric kettle assembly will be activated. When the heating time of the heating tube 23 reaches the set heating time, heating will automatically stop. At this time, even if the temperature sensor 22 is damaged, regardless of whether the kettle thermostat 24 is damaged or not, the electric kettle assembly will not dry boil.

[0035] refer to Figure 1 Furthermore, the water inlet assembly includes a main water inlet pipe 311, a first water supply pipe 312, a second water supply pipe 313, a first water pump 321, and a second water pump 322. The water inlet of the main water inlet pipe 311 is connected to drinking water. The opposite ends of the first water supply pipe 312 are respectively connected to the water outlet of the main water inlet pipe 311 and the cold water inlet of the hot pot assembly. The opposite ends of the second water supply pipe 313 are respectively connected to the water outlet of the main water inlet pipe 311 and the water filling port of the electric kettle assembly. The first water pump 321 is disposed on the first water supply pipe 312 and is electrically connected to the control module. In this embodiment, the first water pump 321 is preferably a diaphragm pump, which is used to pump cold water into the hot pot body 11 of the hot pot assembly. The second water pump 322 is disposed on the second water supply pipe 313 and is also electrically connected to the control module. In this embodiment, the second water pump 322 is preferably a self-priming pump, which is used to pump cold water into the kettle body 21 of the electric kettle assembly.

[0036] Furthermore, a flow meter 33 electrically connected to the control module is provided on the main water inlet pipe 311. This flow meter 33 is used to measure the water flow rate flowing through the main water inlet pipe 311. A water inlet temperature sensor 34 and / or a water inlet switch are electrically connected to the control module on the first water supply pipe 312. The water inlet temperature sensor 34 and / or the water inlet switch are located on the outlet side of the first water pump 321. The water inlet temperature sensor 34 is used to detect the temperature of the water flowing through the first water supply pipe 312. The water inlet switch is used to open or close the first water supply pipe 312 to control the water supply to the hot pot assembly. A one-way valve 35 is provided on the second water supply pipe 313. Located on the outlet side of the second water pump 322, the one-way valve 35 ensures that cold water flows from the second water supply pipe 313 to the electric kettle assembly in a one-way manner, preventing accidental water inflow.

[0037] refer to Figure 1 Furthermore, the water outlet assembly includes a water outlet pipe 41, the water inlet end of which is connected to the hot water outlet of the hot tank assembly. A water outlet temperature sensor 42 and / or a water outlet switch electrically connected to the control module are provided on the water outlet pipe 41. The water outlet temperature sensor 42 is used to detect the outlet temperature of the water flowing through the water outlet pipe 41. The water outlet switch is used to open or close the water outlet pipe 41 to control the water outlet of the hot tank assembly. Of course, the water outlet switch can also be designed to have a temperature measurement function.

[0038] In other embodiments, a scale sensor electrically connected to the control module can be provided on the hot pot assembly to detect the amount of scale accumulated within the hot pot assembly. Alternatively, a scale sensor electrically connected to the control module can be provided on the electric kettle assembly to detect the amount of scale accumulated within the electric kettle assembly. Thus, the tea bar machine can be descaled based on the amount of scale accumulated to prevent excessive scale from affecting the heating effect and the quality of the drinking water.

[0039] Example 2

[0040] refer to Figure 2 The difference between this embodiment and embodiment 1 is that a three-way control valve 36 electrically connected to the control module is provided on the second water supply pipe 313, and the three-way control valve 36 is located in the water inlet direction of the second water pump 322. A connecting water pipe 37 is provided between the three-way control valve 36 and the water supply port of the hot tank assembly. In this way, the hot water in the hot tank assembly is provided to the electric kettle assembly, which is beneficial to shorten the overall heating time of the electric kettle assembly and reduce energy consumption.

[0041] Example 3

[0042] refer to Figure 3The difference between this embodiment and embodiment 1 is that an instant heating body 38 electrically connected to the control module is provided on the second water supply pipe 313, and the instant heating body 38 is located in the water outlet direction of the second water pump 322. In this way, the water supplied to the electric kettle assembly is preheated, which is beneficial to shorten the overall heating time of the electric kettle assembly and improve the heating efficiency of the electric kettle assembly.

[0043] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
