[0022] 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.

[0023] Example 1

[0024] refer to Figure 1 The present embodiment provides a heating device for a tea bar machine, comprising a hot pot assembly, a water inlet assembly, a water outlet assembly and a control module (not shown in the figure). The hot pot assembly comprises a hot pot body 11, a heating tube 12 and a hot water sensor 13. A cold water inlet is provided at the bottom or lower end of the side wall of the hot pot body 11, and a hot water outlet is provided at the top or upper end of the side wall of the hot pot body 11. In the present embodiment, the cold water inlet and the hot water outlet are respectively provided at the bottom and top of the hot pot body 11. The heating tube 12 is provided in the hot pot body 11 and is electrically connected to the control module for heating the water in the hot pot body 11. The hot water sensor 13 is provided in the hot pot body 11 and is electrically connected to the control module for detecting the temperature of the hot water in the hot pot body 11. The control module is used to control the working state of the heating tube 12 according to the hot water temperature detected by the hot water sensor 13, so that the tea bar machine can achieve instant hot water, effectively meeting the user's need for hot water on demand.

[0025] The water outlet end of the water inlet assembly is connected to the cold water inlet of the hot pot body 11, and the water inlet end of the water outlet assembly is connected to the hot water outlet of the hot pot body 11. The control module is electrically connected to the heating pipe 12, the hot water sensor 13, the water inlet assembly, and the water outlet assembly, respectively. The control module is also used to obtain a target flow value of the water inlet assembly based on the water inlet temperature of the water inlet assembly, the hot water temperature detected by the hot water sensor 13, and the water outlet temperature of the water outlet assembly, and control the actual flow value of the water inlet assembly based on the target flow value, thereby automatically controlling the water inlet amount of the hot pot body 11 to maintain a balance between the water inlet and water outlet of the hot pot body 11, thereby ensuring that the tea bar machine can produce hot water instantly.

[0026] 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.

[0027] Furthermore, the hot tank assembly also includes at least one hot tank thermostat 14. In this embodiment, there are two hot tank thermostats 14, which are respectively arranged on opposite side walls of the upper end of the hot tank thermostat 14 and are respectively electrically connected to the control module. Therefore, in extreme cases, when there is no water in the hot tank body 11, the hot water sensor 13 will immediately cut off the power after sensing a certain temperature in a few seconds, so that the heating tube 12 stops working; when the hot water sensor 13 fails, the hot tank thermostat 14 (automatic reset) will immediately cut off the power after sensing a certain temperature; when both the hot water sensor 13 and the hot tank thermostat 14 fail, the hot tank thermostat 14 (manual reset) will immediately cut off the power after sensing a certain temperature. When the whole machine needs to resume operation, it is necessary to cut off the water and electricity, disassemble the whole machine, and restore the disconnected spring clip of the hot tank thermostat 14 to the connected state.

[0028] refer to Figure 1 Furthermore, the water inlet assembly includes a main water inlet pipe 31 and a first water pump 321. The water inlet end of the main water inlet pipe 31 is connected to drinking water, while the water outlet end of the main water inlet pipe 31 is connected to the cold water inlet of the hot tank assembly. The first water pump 321 is installed on the main water inlet pipe 31 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 tank body 11 of the hot tank assembly.

[0029] Furthermore, a flow meter 33 electrically connected to the control module is provided on the main water inlet pipe 31. This flow meter 33 is used to measure the water flow rate flowing through the main water inlet pipe 31. Furthermore, a water inlet temperature sensor 34 and / or a water inlet switch are electrically connected to the control module. In this embodiment, 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 main water inlet pipe 31. The water inlet switch is used to open or close the main water inlet pipe 31 to control the water inflow to the hot tank body 11. The control module is used to obtain a target flow rate value 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 tank assembly, and the water outlet temperature sensor 42 in the water outlet assembly. Furthermore, the control module is used to control the current flow rate value of the first water pump 321 based on the target flow rate value.

[0030] refer to Figure 1 Furthermore, an inner water pipe 311 is provided within the hot tank body 11 and is connected to the outlet end of the main water inlet pipe 31 of the water inlet assembly. A transversely arranged water outlet is provided on the inner water pipe 311. In this embodiment, the inner water pipe 311 is in the shape of an inverted "L" or "T." The lower end of the vertical section of the inner water pipe 311 is connected to the outlet end of the main water inlet pipe 31 of the water inlet assembly, while the free end of the transverse section of the inner water pipe 311 is open to form the outlet. Compared to conventional vertical outlets, this prevents cold water flowing into the hot tank body 11 from flowing directly upward through the inner water pipe 311, thereby preventing the hot water in the entire hot tank body 11 from being immediately diluted by the newly introduced cold water. This reduces the interference of the newly introduced cold water on the hot water in the hot tank body 11, thereby reducing the impact of the newly introduced cold water on the efficiency of hot water output.

[0031] 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. The water outlet pipe 41 is provided with a water outlet temperature sensor 42 and / or a water outlet switch electrically connected to the control module. 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.

[0032] After the water and electricity are connected, the drinking water passes through the flow meter, the first water pump, the water inlet temperature sensor, and finally reaches the hot tank body 11 through the water inlet pipe. At this time, the heating tube 12 heats the incoming water and senses the temperature required by the user through the hot water sensor 13. At the same time, drinking water is continuously added to the hot tank body 11 through the first water pump 32. The hot water to be discharged is discharged through the water outlet pipe 41 and the water outlet temperature sensor 42 and reaches the user's container. The discharged hot water is sensed by the water outlet temperature sensor 42 to see if it is the temperature required by the user.

[0033] In particular, in other embodiments, a scale sensor electrically connected to the control module can be provided on the hot tank body 11 of the hot tank assembly. The scale sensor is used to obtain the amount of scale accumulation in the hot tank assembly. According to the amount of scale accumulation, the control assembly can control the descaling of the tea bar machine to avoid excessive scale affecting the heating effect and the water quality of drinking water.

[0034] Example 2

[0035] refer to Figure 2 The difference between this embodiment and embodiment 1 is that an instant heating body 43 electrically connected to the control module is provided in the water outlet pipe 41. The instant heating body 43 can be located in the water outlet direction or the water inlet direction of the water outlet temperature sensor 42. The control module is used to control the switch of the instant heating body 43 according to the hot water sensor 13, the water outlet temperature sensor 42 and the hot water temperature required by the user. In this way, when the hot water temperature required by the user is higher than the hot water temperature detected by the hot water sensor 13, the control module can control the instant heating body 43 to start, so that the temperature of the hot water flowing out of the water outlet pipe 41 reaches the hot water temperature required by the user, thereby achieving instant hot water while effectively meeting the user's water temperature requirements.

[0036] 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.
