Description

Technical Field

[0001] This utility model relates to a pressure relief structure for a coffee machine. Background Technology

[0002] Coffee has become a daily beverage for young people in my country. With the continuous promotion of coffee culture, coffee shops are also increasing. Currently, when coffee machines extract coffee, the extractor needs to be installed on the brewing head. Hot water from the brewing head flows through the extractor to obtain coffee. However, in practice, it has been found that the extractor is difficult to disassemble after each extraction, mainly due to excessive internal pressure, which is not user-friendly, especially for petite women.

[0003] Therefore, it is necessary to improve existing coffee machines. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a pressure relief structure for a coffee machine, which solves the problem of the difficulty in disassembling the extractor by setting up a pressure relief structure.

[0005] To achieve the above objectives, this utility model provides a pressure relief structure for a coffee machine. The coffee machine has a brewing head and a water tray on its front side, with the water tray located below the brewing head. The brewing head is connected to the first end of a three-way solenoid valve. The second end of the three-way solenoid valve is a water inlet, and the third end of the three-way solenoid valve is a pressure relief port. The coffee machine has a pipe connector inside, which has an input end and an output end. The input end is connected to the third end of the three-way solenoid valve through a pressure relief pipe, and the output end is connected to the inside of the water tray.

[0006] In one or more embodiments, the coffee machine has a front panel with an interface on the inside of the front panel, the output end of the pipe connector is inserted into the interface, and the water tray has an opening and is located below the interface.

[0007] In one or more embodiments, the pipe fitting has a fixing part with a mounting hole through which a screw can pass, the screw being connected and fixed to the coffee machine.

[0008] In one or more embodiments, the front side of the front plate is provided with a mounting platform for installing a water receiving tray, the mounting platform is provided with a guide step, the water receiving tray has a guide groove that slides with the guide step, and the guide step extends back and forth.

[0011] In one or more embodiments, the panel is made of stainless steel.

[0012] Compared with the prior art, the advantages of this invention are: the coffee machine has a pressure relief structure. Specifically, after the pressure relief port is opened by the three-way solenoid valve, the pressure is discharged from the pipe joint into the water tray, thereby solving the problem that the extractor is difficult to disassemble due to high pressure. At the same time, the water tray is used to collect the water vapor and condensate discharged from the pressure relief port. Attached Figure Description

[0015] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0016] Please refer to the appendix. Figure 1-2 This utility model provides a pressure relief structure for a coffee machine. The coffee machine has a brewing head 1 and a water tray 2 on the front side. The water tray 2 is located below the brewing head 1. The brewing head 1 is connected to the first end of a three-way solenoid valve. The second end of the three-way solenoid valve is the water inlet, and the third end of the three-way solenoid valve is the pressure relief port. Specifically, the first and second ends of the three-way valve form the water inlet path of the brewing head, and the third end is connected to the water inlet path. When the third end is opened, the pressure in the water inlet path can be released. The coffee machine has a pipe connector 3 inside. The pipe connector 3 has an input end 31 and an output end 32. The input end 31 is connected to the third end of the three-way solenoid valve through the pressure relief pipe. The output end 32 is connected to the inside of the water tray 2. The discharged high-pressure water vapor or water can enter the inside of the water tray through the pipe connector, and the water tray is used to collect condensate.

[0017] The coffee machine has a front panel 4, with an insertion interface on the inner side of the front panel. The output end 32 of the pipe connector 3 is inserted into the insertion interface. The water tray 2 has an opening 5 and is located below the insertion interface. The pipe connector is fixed to the front panel by insertion and can directly discharge water vapor or water into the water tray, reducing the need for transfer structures.
