Abstract
Description
Technical Field
[0001] The utility model relates to the field of coffee machines, in particular to a hot and cold coffee machine. Background Art
[0002] The working principle of a coffee machine can be simply summarized as heating a fluid and spraying it at high pressure, mixing it with coffee grounds to produce a rich cup of coffee. The coffee machine's structure primarily consists of a water reservoir, a boiler, a filter, and a water outlet. The water reservoir stores the fluid and heats it to the desired temperature via the boiler. The boiler heats the fluid until it reaches the desired temperature for coffee. The filter holds the coffee grounds in place, preserving their purity and flavor. The water outlet uses a high-pressure pump to spray the heated fluid onto the coffee grounds, thoroughly mixing them.
[0003] However, the water pipes of traditional coffee machines pass through the water storage unit, boiler, filter and water outlet unit in sequence. The fluid transported from the water storage unit must pass through the boiler to reach the water outlet unit. When the coffee machine needs to make cold brew coffee, the fluid passing through the boiler is easily affected by the residual heat of the heating mechanism and heats up, affecting the production effect of the cold brew coffee and the use effect of the coffee machine, which needs to be improved.
