Description

Technical Field

[0001] The invention relates to the technical field of coffee machine cleaning, in particular to a water channel system with ultrasonic cleaning and extraction functions. Background Art

[0002] After a period of use, scale will accumulate in the internal pipes and boiler of the coffee machine, and tablets need to be added for descaling and cleaning. However, the effect is not always obvious and the ingredients of the tablets will remain in the water system, affecting user experience and food hygiene. Similarly, the brewing head will become difficult to clean due to erosion by coffee grounds and residual coffee liquid.

[0003] When the existing coffee machines realize the machine cleaning function, they only have a simple program-controlled water pump to perform a series of actions. This only performs a simple flushing on the inside of the pipe, and the effect of cleaning the sediment inside the pipe is limited. In addition, the descaling function only puts specific tablets in the water tank, and then uses the program execution control system to pass the tablet ingredients through the pipe system. This will have a certain cleaning effect, but with the accumulation of sediment, the effect of this cleaning method will become worse and worse, and finally the machine needs to be disassembled for cleaning, which is a large workload.

[0004] The existing patent CN103519685A provides a coffee machine with ultrasonic cleaning function, but it uses an external ultrasonic cleaning device on one side of the coffee machine to clean the detachable parts, and has no cleaning effect on the internal piping system of the coffee machine.

[0005] The existing patent CN221769799U provides a coffee machine with ultrasonic cleaning function, but it uses an external ultrasonic cleaning device on one side of the coffee machine to clean and dry the detachable parts, and has no cleaning effect on the internal piping system of the coffee machine.

[0006] Therefore, those skilled in the art provide a water system with ultrasonic cleaning and extraction functions to solve the problems raised in the above background technology. Summary of the invention

Obviously, the specific embodiments described are only part of the specific embodiments of the present invention, not all of the specific embodiments. Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1 As shown, a specific embodiment of the present invention provides a water system with ultrasonic cleaning and extraction functions, including a water tank 101, a three-way connector 102, a two-way solenoid valve 103, a first ultrasonic generating module 104, a flow meter 105, a water pump 106, a three-way connector 107, a two-way solenoid valve 108, a second ultrasonic generating module 109, a boiler 110, a three-way solenoid valve 111, a brewing head 112 with integrated ultrasonic generating function, a high-pressure funnel 113 and a waste water tray 114;

[0040] The water tank 101 is provided with a water tank outlet 1011, which is connected to the water inlet end 201 on the three-way joint 102 through a pipeline, the water outlet end 202 on the three-way joint 102 is connected to the water inlet 301 of the two-way solenoid valve 103, the water outlet 302 on the two-way solenoid valve 103 is connected to the first ultrasonic generating module 104, the water outlet end 203 on the three-way joint 102 is connected to the flow water inlet end 501 on the flow meter 105 through a pipeline, the flow water outlet end 502 on the flow meter 105 is connected to the water pump inlet 602 on the water pump 106 through a pipeline, and the water pump outlet 601 on the water pump 106 is connected to the water inlet end 701 on the two-way joint 107 through a pipeline. The water outlet end 4 703 on the two-way connector 107 is connected to the water inlet 2 801 on the two-way solenoid valve 108, the water outlet 2 802 on the two-way solenoid valve 108 is connected to the second ultrasonic generating module 109, the water outlet end 3 702 on the two-way connector 107 is connected to the boiler water inlet 1001 on the boiler 110, the boiler water outlet 1002 on the boiler 110 is connected to the three-way valve inlet 1101 on the three-way solenoid valve 111 through a pipeline, the three-way valve outlet 2 1103 on the three-way solenoid valve 111 is connected to the waste water tray 114 through a pipeline, and the three-way valve outlet 1 1102 on the three-way solenoid valve 111 is connected to the brewing head water inlet 1203 on the brewing head 112 with integrated ultrasonic generating function through a pipeline.

[0041] The brewing head 112 with integrated ultrasonic generating function is evenly provided with ultrasonic generator 1 1201 , ultrasonic generator 2 1202 and ultrasonic generator 3 1204 .

[0042] Working principle: When the water system with ultrasonic cleaning and extraction functions is used, when the user performs a cleaning action, the control system starts and executes the cleaning program. At this time, the high-pressure funnel 113 is screwed into the brewing head 112 with an integrated ultrasonic generating function, and at the same time, the water pump 106 starts to operate to extract water from the water tank 101 to fill the entire coffee machine pipeline system. At this time, the two-way solenoid valve 103, the two-way solenoid valve 2 108, and the three-way solenoid valve 111 start to operate, and at the same time, the first ultrasonic generating module 104, the second ultrasonic generating module 109, and the brewing head with an integrated ultrasonic generating function are connected to the coffee machine. Ultrasonic generator 1 1201, ultrasonic generator 2 1202 and ultrasonic generator 3 1204 are evenly distributed on the brewing head 112, which start to operate and provide an ultrasonic source for the entire management, so that the sediment inside the pipeline system is cavitated and falls off, and is discharged along the high-pressure funnel 113 as the water pump 106 works. When the program is executed, the cleaning is completed. Similarly, while performing ultrasonic cleaning, the ultrasonic cavitation effect will also disinfect the microorganisms inside the pipeline that have entered the pipeline with the external water source and have already been at the brewing head, thereby more effectively improving the hygiene quality of the coffee machine.

[0043] When the user performs cold brew coffee operation, the high-pressure funnel 113 is filled with coffee powder and then screwed into the brewing head 112 with integrated ultrasonic generating function. At the same time, the water pump 106 starts to work to pump water from the water tank 101 to the brewing head 112 with integrated ultrasonic generating function to perform coffee cold brewing. At this time, the three ultrasonic generators at the brewing head 112 with integrated ultrasonic generating function start to work to reinforce the user's cold brewing action. After the coffee extraction is completed, the water pump 106 and the ultrasonic generator on the brewing head 112 with integrated ultrasonic generating function stop working.

[0044] Although specific embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the specific embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
