[0002] After a tea machine has been used for a long time, tea scale will remain on the inner wall of its pipes. When tea scale appears on the inner wall of the pipes, it will affect the quality of the tea. At the same time, the accumulated tea scale will also affect the normal water output speed. In order to clean the tea scale, cleaning water is generally injected directly into the tea machine, and the tea scale is flushed away by the continuous flow of cleaning water.

[0003] However, this cleaning method has some problems: the cleaning water generally flows out directly from the tea spout after cleaning, which is inconvenient to collect. The operator needs to connect a drain pipe or place a water container at the tea spout to collect the cleaning water when using it, and remove the drain pipe or water container after cleaning, which is very complicated.

[0015] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0016] like Figures 1 to 3 , which is a schematic diagram of the structure of the automatic cleaning system of the instant tea machine provided by the present invention. The automatic cleaning system of the instant tea machine includes a tea barrel assembly 10 and a refrigeration assembly 20 connected in sequence. The automatic cleaning system of the instant tea machine also includes other functional modules, such as a controller connected to the water pump 20 and a distribution box, etc. These are well known to those skilled in the art and will not be described in detail here.

[0017] The tea barrel assembly 10 includes a tea barrel body 11 , a water outlet pipe 12 inserted into the tea barrel body 11 , and a feed solenoid valve 13 provided on the water outlet pipe 12 .

[0018] It should be noted that a cleaning water pipe is provided on one side of the water inlet 111 of the tea barrel body 11 for injecting cleaning water into the tea barrel body 11. Since the injection of cleaning water mainly relies on the pump body and the water pipe, the connection structure of the water pipe and the pumping principle of the pump body are well known to those skilled in the art and will not be described in detail here and are not shown in the figure.

[0019] The tea barrel body 11 is used for hot tea. A water inlet 111 is provided at the top of the tea barrel body 11 to facilitate the entry of hot tea and cleaning water. The water outlet pipe 12 is inserted into the top of the tea barrel body 11, with the end of the water outlet pipe 12 close to the bottom of the tea barrel body 11, thereby maximizing the amount of liquid drawn from the tea barrel body 11. The feed solenoid valve 13 is used to extract liquid from the tea barrel body 11. The feed solenoid valve 13 is controllably connected to the controller 28 described below. The specific control method will be described in detail below.

[0020] The refrigeration assembly 20 includes a shell 21, a refrigeration pipe 22 coiled in the shell 21, a refrigeration body 23 arranged in the shell 21 and located on one side of the refrigeration pipe 22, a metering pump 24 arranged on the refrigeration pipe 22, a tea outlet 25 arranged on the side wall of the shell 21 and connected to the metering pump 24 through a pipe, a three-way solenoid valve 26 arranged between the metering pump 24 and the tea outlet 25, a drain port 27 opened on the side wall of the shell 21, and a controller 28 arranged in the shell 21 and controlled and connected to the feed solenoid valve 13 and the three-way solenoid valve 26.

[0021] The housing 21 includes a main housing 211 and a secondary housing 212 disposed on one side of the main housing 211. The main housing 211 is used to accommodate the refrigeration pipe 22 and the refrigeration body 23. The secondary housing 212 is used to install the tea outlet 25 and the controller 28.

[0022] The refrigeration pipe 22 is a copper pipe, and the refrigeration pipe 22 is in close contact with the refrigeration main body 23. It should be noted that the refrigeration main body 23 includes a refrigeration compressor 231, a heat dissipation spiral tube 232 connected to the refrigeration compressor 231, and an aluminum ingot 233 connected to the refrigeration compressor 231. The refrigeration pipe 22 is inserted into the aluminum ingot 233 and contacts the aluminum ingot 233, so that the tea in the refrigeration pipe 22 is cooled. The refrigeration main body 23 will continue to refrigerate the aluminum ingot, thereby refrigerating the liquid in the refrigeration pipe 22, and then reducing the temperature of the tea. The principle of the refrigeration main body 23 is the heat exchange principle. Since the specific structure and refrigeration principle of the refrigeration main body 23 are well known to those skilled in the art, they will not be described here.

[0023] The liquid inlet of the metering pump 24 is connected to the refrigeration pipe 22, and the discharge port of the metering pump 24 is connected to a three-way solenoid valve 26. One liquid outlet of the three-way solenoid valve 26 is connected to the tea outlet 25, and the other liquid outlet is connected to the drain port 27.

[0024] The tea outlet 25 is provided at the bottom of the auxiliary shell 212 , and a control panel 213 is provided on the outer wall of the auxiliary shell 212 . The control panel 213 is connected to the controller 28 , and the user can open or close the valve switch by operating the control panel 213 .

[0025] The three-way solenoid valve 26 is used to control the opening and closing of the tea outlet 25 and the liquid drain 27. The liquid drain 27 is located on the side wall of the main housing 211 facing away from the auxiliary housing 212. When in use, the auxiliary housing 212 is generally positioned toward the operator, so that the liquid drain 27 is close to the wall, facilitating the routing of water pipes.

[0026] During use, the operator pre-sets the daily cleaning time. When the cleaning time is up, the controller 28 will count down for a period of time, and then open the valve of the cleaning water pipe to allow the cleaning water to directly enter the tea bucket body 11. By providing a metering component on the cleaning water pipe or a liquid level detection device in the tea bucket body 11, the height of the cleaning water injected into the tea bucket body 11 does not exceed the water injection port 111 of the tea bucket body 11. After the water injection is completed, the controller 28 controls the feed solenoid valve 13 to open, and the cleaning water will flow along the outlet pipe 12 into the refrigeration pipe 22 and clean the refrigeration pipe 22. The metering pump 24 will also open with the opening of the feed solenoid valve 13. The metering pump 24 extracts the cleaning water in the refrigeration pipe 22 and injects it into the three-way solenoid valve 26. The three-way solenoid valve 26 will first open the channel connected to the tea outlet 25 and close the channel connected to the drain port 27, so that the cleaning water cleans the tea outlet 25. After a short cleaning, the three-way solenoid valve 26 will close the channel connected to the tea outlet 25 and open the channel connected to the drain port 27, and discharge the remaining cleaning water directly from the shell 21.

[0027] Compared with the prior art, the automatic cleaning system of the instant tea drinking machine provided by the present invention is provided with the metering pump 24, so that a fixed amount of cleaning water can be discharged from the tea outlet 25 during cleaning, avoiding excessive cleaning water that is inconvenient to collect. By connecting the water outlet end of the metering pump 24 to the three-way solenoid valve 26, the two water outlet ends of the three-way solenoid valve 26 are respectively connected to the tea outlet 25 and the drain port 27, so that after the tea outlet 25 is cleaned, the cleaning water can be introduced into the drain port 27 for discharge. It only takes a water pipe to be fixed at the drain port 27 to directly lead the cleaning water to a preset position, which simplifies the cleaning process and realizes automatic cleaning.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
