Benefits of technology

The present invention is about a coffee machine that has a flow guiding device. This device helps to direct liquid into a brewing chamber for making coffee. The machine also has a detachable first lid body, which makes it easy to clean. The technical effect of this invention is to improve the performance and cleanliness of coffee machines.

Problems solved by technology

Since the first lid body is fixedly connected to the guiding pipe, at least one end of the first lid body is fixed and cannot be completely detached from the main body, which causes the inconvenience in the cleaning of the coffee machine, in particular the cleaning of the first lid body.
There is a gap between the second lid body and the brewing chamber, which causes that small coffee particles in the brewing chamber are escaped with steam from the gap when brewing coffee.
However, the grinding and filtering device of such coffee machines has poor filtering effect.
In addition, since the liquid in the bottom portion of the brewing chamber is mixed with the deposited particles at the bottom portion, and can hardly be discharged from the filter, a part of liquid and coffee particles is remained at the bottom of the brewing chamber, thereby causing waste.

embodiment 1

[0075]As shown in FIG. 1, a coffee machine comprises a main body 1, a grinding and filtering device, a water tank 2 and a heating device 3. The grinding and filtering device, the water tank 2 and the heating device 3 is provided inside the main body 1. A main body opening is provided at a top of the main body 1. The coffee machine further comprises a first lid body 6 for covering the main body opening. The grinding and filtering device comprises a chamber 41 for containing liquid and coffee particles, a grinding assembly for grinding coffee particles, a motor 43 connected to the grinding assembly and for driving the grinding assembly, and a first filter 44 for filtering coffee liquid in the chamber 41. As shown in FIGS. 1 and 4, in the present embodiment, the chamber 41 is placed into the main body 1 through the main body opening and is engaged with the main body 1. The chamber 41 comprises a brewing chamber 412 and a collecting chamber 413. A liquid channel 411 communicated with th...

embodiment 2

[0086]The present embodiment is substantially the same as that of Embodiment 1 except that the structure of the flow guiding device is different. The flow guiding device of the coffee machine in the present embodiment is similar to that shown in FIG. 2. However, the flow guiding device of the coffee machine in the present embodiment does not have a second flow guiding channel 52. The flow guiding device of the coffee machine in the present embodiment comprises a first flow guiding channel 51, and the first end 511 of the first flow guiding channel 51 is connected to the heating device 3. The brewing chamber 412 is provided with a brewing chamber through hole corresponding to a second end 512 of the first flow guiding channel 51. The second end 512 of the first flow guiding channel 51 is inserted into the brewing chamber 412 through the brewing chamber through hole.

embodiment 3

[0087]The present embodiment is substantially the same as that of Embodiment 1 except that the structure of the blocking device is different. The whole structure of the coffee machine in the present embodiment is similar to that shown in FIG. 1 and FIG. 2. As shown in FIG. 10 and FIG. 12, the blocking device is a sheet-like elastic single piece 72 fixed onto the upper opening 211. The elastic single piece 72 has a circular cross section, which corresponds to the shape of the corresponding upper opening 211. A middle portion of the elastic single piece 72 is provided with a cutout 721. The periphery of the elastic single piece 72 is provided with a convex wall 722 which tightly surrounds a flange 213 and is fixed to an outer side wall of the flange 213. When the first pipe portion 521 of the second flow guiding channel 52 is inserted into the upper opening 211, the cutout 721 of the elastic single piece 72 is opened by the first pipe portion 521 and thus the first pipe portion 521 of...
