Description

Technical Field

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

[0002] Coffee is a popular beverage among consumers. The preparation of coffee involves at least grinding and extraction steps, and some specialty coffees also require milk frothing. To meet diverse consumer needs, various coffee machines with grinding, extraction, and steaming functions have emerged. In most coffee machines on the market, the grinding component responsible for grinding coffee beans is often directly installed inside the main casing. This not only makes installation and maintenance of the grinding component inconvenient, but also occupies a significant amount of space, resulting in a large overall size for the multi-functional coffee machine. Consumers need to reserve ample space for the machine, while manufacturers incur higher packaging and transportation costs. For example, Chinese patent document CN216060268U discloses a novel coffee grinder, specifically comprising a coffee machine casing, a base on the bottom side of the casing, an opening at the top of the casing, a grinding component for grinding coffee beans housed within the casing, and four connecting bolts on the bottom side of the base, all of which are connected to the coffee machine casing. In this existing coffee machine, the grinding component is located inside the coffee machine casing, and the base is fixedly connected to the bottom of the coffee machine casing. This structure is not conducive to the installation and later maintenance of the grinding component, and the overall size is relatively large.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a coffee machine with a grinding component that is easy to install and maintain, compact in size, and modular in design, in order to overcome the shortcomings of the prior art.

[0005] A coffee machine designed for this purpose includes a base and a grinding device. The base is equipped with a support, and the grinding device is independently set and connected to the support on its side, so that the grinding device is suspended in the air. A powder receiving space for placing a coffee powder container is provided between the powder outlet end at the bottom of the grinding device and the base.

[0006] It also includes a mounting shell, a water tank, and a liquid delivery assembly. The mounting shell is mounted on a base. The mounting shell is equipped with an extraction assembly and / or a steam assembly. The liquid delivery assembly is connected to the water tank and the extraction assembly and / or the steam assembly via water passages.

[0007] The mounting housing has an integrally formed first mounting position and / or second mounting position. The extraction component is fixedly mounted on the first mounting position, and the steam component is fixedly mounted on the second mounting position. When the first mounting position and the second mounting position are set at the same time, the first mounting position and the second mounting position are connected to each other through a connecting part. One side of the connecting part is in contact with the extraction component, and the other side of the connecting part is in contact with the steam component.

[0008] The mounting housing has an integrally formed container positioning part for mounting a coffee powder container. The container positioning part is located in the powder receiving space between the powder outlet end at the bottom of the grinder and the base. The powder outlet end at the bottom of the grinder corresponds vertically to the coffee powder container on the container positioning part. The container positioning part is integrally connected to the first mounting position or the second mounting position.

[0009] The support is provided with a slot, and the grinding device is provided with an outwardly protruding insertion part. The insertion part and the slot are inserted into each other, so that the grinding device is fixedly installed on the support.

[0010] The groove wall of the insertion slot is provided with several inwardly protruding positioning ribs, and the insertion part is locked between the positioning ribs.

[0011] It also includes a detachable water tank that is mounted on the base. The water tank has an installation groove, and the bracket is installed on the installation groove. The insertion groove protrudes outward relative to the side wall of the water tank.

[0012] The top of the mounting slot is provided with a positioning rib, and the top of the bracket is provided with a positioning groove. The positioning rib is inserted into the positioning groove to position the bracket on the mounting slot.

[0013] The base is provided with a support boss, the water tank is detachably installed on the support boss, and the bracket is fixedly installed on the support boss; the liquid conveying assembly is installed inside the support boss.

[0014] The top of the support boss is provided with a plug-in protrusion, and the bottom of the water tank is provided with a plug-in groove. The plug-in protrusion and the plug-in groove are detachably positioned and plugged into each other, so that the water tank can be detachably installed on the support boss.

[0015] The grinding device in this invention is set independently and suspended above the base by a bracket. The grinding device is set independently on the outside, which facilitates installation and later maintenance. The independent setting makes it smaller in size, which is better for combining with other functional devices. The overall size of the coffee machine is smaller, which reduces the space occupied and reduces packaging and transportation costs.

[0016] In this invention, the extraction component and / or steam component are integrated and mounted on the mounting housing, making the various functional components integrated together. This results in a more compact overall structure for the coffee machine, allowing it to be made smaller and suitable for miniaturized design. Attached Figure Description
