Description

Technical Field

[0001] This utility model relates to the field of beverage equipment, and in particular to a temperature device for a coffee machine tap. Background Technology

[0002] Coffee machines are now a common beverage appliance in most homes and businesses. As people's living standards improve and their acceptance of coffee culture increases, more and more people are pursuing the taste and aroma of freshly ground coffee. Based on different needs, usage scenarios, and types of coffee, coffee machines have also developed into various types to meet the preferences of different users. For example: American drip coffee makers are the most common type of home coffee machine, suitable for making black coffee or Americano daily. They work by dripping heated water into a filter containing coffee grounds, allowing the coffee to flow naturally into a pot or cup below.

[0003] Italian-style semi-automatic and fully automatic coffee machines are primarily used to make espresso and espresso-based beverages such as lattes and cappuccinos. Semi-automatic models require users to manually tamp the coffee grounds and control the extraction time, making them suitable for those who enjoy hands-on operation and pursue high-quality coffee. Fully automatic models, on the other hand, automate the entire process from grinding to extraction, and can even automatically froth milk, offering convenient operation and making them suitable for users who demand both quality and efficiency.

[0004] Capsule coffee machines use pre-packaged coffee capsules; simply insert the capsule and press a button to quickly brew a cup of coffee. Their advantages include ease of operation, convenient cleaning, and consistent flavor. Disadvantages include higher capsule costs and limited capsule selection.

[0005] Existing American drip coffee machines start dispensing water after heating, but at this time, there will be residual low-temperature water in the hot water pipe that did not flow out of the drip nozzle during the previous drip. This water flows out of the drip nozzle and into the coffee grounds before reaching the ideal extraction temperature, causing the initial extraction temperature to be substandard. This significantly affects the taste and stability of the extracted coffee, easily leading to under-extraction in the early stage and over-extraction in the later stage. In addition, most American drip coffee machines use a single-pipe design, which can easily cause the residual low-temperature water to flow back, contaminating the water source and posing a risk of cross-contamination.

The plug-in part 206 matches the plug-in groove 402 to form a plug-in. After the plug-in is completed, in order to enhance its connection stability, in this embodiment, bolts are preferably used to fix the flow guiding module 2 to the body cover 401. Other suitable fixing structures or methods can also be used, such as snap-fit ​​connection, welding, bonding, riveting, etc.; or according to the actual working conditions, no additional fixing structure can be set, and the connection can be achieved by plug-in cooperation alone.

[0045] In use, when coffee needs to be extracted, the extraction container 405 is placed on the heat insulation pad 404 and aligned with the spray nozzle 101. Then, the ground coffee powder is placed into the filter element 406, and the filter element 406 is placed on the extraction container 405. The hot extraction is then started via the control panel 7. During the extraction process, external water is first transferred to the water storage device 6 through a water circuit, and then from the water storage device 6 to the heating device 5 through a water circuit. The heating device 5 heats the water, and then the hot water is transferred from the heating device 5 to the hot water delivery pipe 202 through the water circuit. The hot water passes through the hot water delivery pipe 202 and then through the temperature sensor 301. At this time, the temperature sensor 301 measures the temperature of the passing hot water in real time. When the temperature meets the set temperature, the temperature sensor 301 transmits a signal to the control valve 302. The control valve 302 connects to the pipe connected to the spray module 1, and the hot water is transferred from the control valve 302 to the shower inlet 144 on the shower cap 143. Finally, the hot water flows from the vortex tank 142... The hot water is delivered to the spray nozzle 101 to spray the coffee powder on the filter element 406. When hot water that does not meet the set temperature passes through the temperature sensor 301, the temperature sensor 301 transmits a signal to the control valve 302.

The fluid delivery pipeline 201 is aligned with the fluid insertion port 421 and then inserted to complete the installation of the flow guiding module 2 and the spray module 1. To enhance the connection stability, bolts can be used to fix the flow guiding module 2 to the machine body cover 401, or other suitable fixing structures or methods can be used, such as snap-fit ​​connection, welding, bonding, riveting, etc.; or according to the actual working conditions, no additional fixing structure can be set, and the connection can be achieved by simply plugging in.
