Abstract
Description
Technical Field
[0001] The utility model relates to the field of coffee machines, in particular to a high- and low-pressure relief joint in a coffee machine. Background Art
[0002] When the coffee machine has finished making coffee or steam (for making milk foam), or when the heating stops during the process, the boiler is still hot and the pressure will rise differently. In order to prevent the high pressure from causing the pipe to burst, the pressure reducing valve needs to be activated to safely discharge the internal pressure through the condenser. In a double-pump double-boiler coffee machine, the steam and coffee functions can run at the same time, so the pressure reducing system must also support simultaneous operation. In the prior art, two separate pressure relief pipelines are generally used, and the pressure relief pipelines are controlled by two independent solenoid valves to prevent high-pressure and low-pressure steam and water from interfering with each other, but this makes the pipeline design more complicated and the cost is also higher.
