Abstract
The invention discloses a coffee grinding machine which comprises a machine body, an automatic grinding device and a funnel; the automatic grinding device is provided with a grinding room and a powder feed trough, and a powder outlet of the powder feed trough is positioned above the funnel. The coffee grinding machine is characterized in that a rotatable valve block positioned in the powder feed trough is provided with a gap which can contain coffee powder and the powder outlet and the grinding room are always insulated mutually whatever the valve block is rotated to any position. After the structure is adopted, the powder outlet and the grinding room are always insulated mutually whatever the valve block in the powder feed trough of the coffee grinding machine is rotated to any position, thereby effectively preventing the automatic grinding device of the coffee grinding machine from working irregularly because water vapor in the funnel enters the grinding room during the process of brewing coffee; compared with the prior art, the coffee grinding machine of the invention has the advantages of small occupying area and compact structure.
Description
Technical field
The present invention relates to a kind of coffee machine, particularly a kind of coffee machine with bean-grinding function.
Background technology
Existing coffee machine with bean-grinding function, be after the coffee powder that coffee bean is made is transported to funnel, hot water enters funnel the coffee powder in the funnel is brewed then, when preventing to infuse coffee, water vapour enters the bean milling machine structure and makes the bean milling machine structure cisco unity malfunction of coffee machine, U.S. patent of invention US5615601 has disclosed a kind of coffee machine that has bean-grinding function, the funnel of this coffee machine can move between mill beans position and coffee brewing position, funnel moves to mill beans position and receives coffee powder during the mill beans, funnel moves to the coffee brewing position and receives hot water the coffee powder in the funnel is brewed when infusing coffee, there is coffee machine in above-mentioned funnel moving structure and takes up room greatly, and structure is owed compact shortcoming.
Summary of the invention
In order to overcome the above-mentioned defective of prior art, the invention provides a kind of bean-grinding coffee machine of compact conformation.
The technical solution adopted in the present invention is: a kind of bean-grinding coffee machine comprises body, automatic grinding device and funnel; Automatic grinding device is provided with grinding chamber and powder feeding groove, the meal outlet of powder feeding groove is positioned at the top of funnel, a rotatable valve piece that it is characterized in that being positioned at the powder feeding groove has a breach that can hold coffee powder, and the valve piece rotates to any position makes meal outlet and grinding chamber isolate mutually all the time.
Described valve piece is positioned at the top of meal outlet; During the rotation of valve piece, its breach staggers, partially overlaps or overlap fully with meal outlet.
When described breach and meal outlet partially overlapped, the part coffee powder in the breach fell under gravity in the funnel; When described breach overlapped fully with meal outlet, the whole coffee powders in the breach fell under gravity in the funnel.
Described valve piece is connected with helical gear by pin, and a motor is provided with a worm screw and is connected with helical gear.
After adopting above structure, valve piece in the powder feeding groove of the present invention rotates to any position makes meal outlet and grinding chamber isolate mutually all the time, thereby makes the water vapour that effectively prevents when infusing coffee in the funnel enter the automatic grinding device cisco unity malfunction that grinding chamber causes coffee machine; Compared with prior art, bean-grinding coffee machine of the present invention have take up room little, the advantage of compact conformation.
Description of drawings
Fig. 1 is the partial sectional view of coffee machine of the present invention;
Fig. 2 is the three-dimensional exploded view of mill of the present invention;
Fig. 3 to Fig. 7 is valve piece of the present invention rotates to diverse location in the powder feeding groove a schematic diagram.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of bean-grinding coffee machine of the present invention comprises body 1, automatic grinding device 2 and funnel 3; Automatic grinding device 2 is provided with grinding chamber 21 and powder feeding groove 22, and the meal outlet 221 of powder feeding groove 22 is positioned at the top of funnel 3; Be provided with a rotatable valve piece 23 in the powder feeding groove 22, valve piece 23 has a breach 231 that can hold coffee powder, and valve piece 23 is positioned at the top of meal outlet 221.
Reference 3 is to shown in Figure 7, and valve piece 23 is in rotary course, and its breach 231 staggers, partially overlaps or overlap fully with meal outlet 221; As shown in Figure 3, when valve piece 23 rotates to when breach 231 and grinding chamber 3 are interconnected, coffee powder will enter breach 231; As shown in Figure 4, when valve piece 23 was rotated further, the coffee powder in the breach 231 was also along with rotation; As shown in Figure 5, when valve piece 23 turns to when allowing breach 231 and meal outlet 221 partially overlap, the part coffee powders in the breach 231 fall under gravity in the funnel 3; As shown in Figure 6, when valve piece 23 turns to when allowing breach 231 overlap fully with meal outlet 221, the whole coffee powders in the breach 231 fall under gravity in the funnel 3; As shown in Figure 7, valve piece 23 can be rotated further, and just finishes a powder feeding cycle when breach 231 is back to position shown in Figure 3.In mill beans process, valve piece 23 can constantly rotate, and breach 231 is constantly delivered to coffee powder in the funnel 3.In a powder feeding cycle, no matter valve piece 23 rotates to any position makes meal outlet 231 and grinding chamber 21 isolate mutually all the time; When therefore infusing coffee, rotate on any position when no matter valve piece 23 quits work, meal outlet 231 is total isolates mutually with grinding chamber 21, prevents effectively when infusing coffee that funnel 3 interior water vapours from entering automatic grinding device 2 cisco unity malfunctions that grinding chamber 21 causes coffee machine thereby make.
Certainly, the invention is not restricted to the embodiments described, can carry out many modifications under the prerequisite that does not deviate from protection domain of the present invention, drives spur gear as the worm drive helical gear being replaced with spur gear.
Claims (2)
