The beneficial effects of the invention are as follows：When close, the coffee machine system meeting that by the device detects user of coffee machine system
Energy saver mode is automatically exited from, ready state is returned to immediately；Left when coffee machine system detects user by the device,
And there is no user close within the system default time, coffee machine system can be automatically into energy saver mode.
Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, makes required in being described below to embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for
For those of ordinary skill in the art, on the premise of not paying creative work, it can also obtain other according to these accompanying drawings
Accompanying drawing, wherein：
Fig. 1 show the overall schematic that a kind of coffee machine coffee bean of the invention lacks beans detection means；
Fig. 2 show the infrared distance sensor frame diagram that a kind of coffee machine coffee bean of the invention lacks beans detection means.
Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model that the present invention is protected
Enclose.
Fig. 1-2 is referred to, a kind of coffee machine coffee bean is provided in one particular embodiment of the present invention and lacks beans detection dress
Put, including：Coffee machine beans box 1, coffee bean 2, infrared distance sensor 3 and central processing unit 4, described coffee bean 2 are located at institute
Inside the coffee bean box 1 stated, described infrared distance sensor 3 is located at the described outer wall of coffee machine beans box 1, the center processing
Connection is controlled between device 4 and infrared distance sensor 3.
Described infrared distance sensor includes signal processing circuit, mu balanced circuit, oscillating circuit, output circuit, red
Outer transmitting diode drive circuit, outer reception diode and infrared-emitting diode.Described infrared-emitting diode and driving
It is connected with each other between circuit, and drive circuit persistently drives infrared-emitting diode to launch infrared light, and after reflection, irradiation
Infrared receiving diode on to infrared distance sensor.Connection, institute are controlled between the signal processing circuit and output circuit
The infrared light received by infrared receiving diode is stated to handle by output circuit output voltage values by signal processing circuit.It is described
The magnitude of voltage that central processing unit is exported to infrared distance sensor carries out analog-to-digital conversion, draws barrier and infrared distance sensor
The distance between.The distance between described barrier and infrared distance sensor and infrared distance sensor sensor output voltage
Value is inversely proportional.
In a specific embodiment, by infrared distance sensor device in coffee machine beans cassette bottom portion, between leave it is certain
Gap.
Fig. 2 is infrared distance sensor frame diagram, mainly by infrared receiving diode, signal processing circuit, infrared emission
This 7 module compositions of diode, infrared-emitting diode drive circuit, mu balanced circuit, oscillating circuit, output circuit.When it is complete from
On dynamic coffee machine after electricity, infrared-emitting diode drive circuit persistently drives infrared-emitting diode to launch infrared light, through barrier
Hinder after thing reflects, be irradiated to the infrared receiving diode on infrared distance sensor, then after signal processing circuit is handled by
Output circuit output voltage values, magnitude of voltage that coffee machine system CPU is exported to sensor carries out analog-to-digital conversion, then by algorithm,
Just the distance between barrier and sensor can be drawn；In effective range, the distance between barrier and sensor and sensing
Device output voltage values are inversely proportional i.e., and the distance between barrier and sensor are more remote, and sensor output voltage value is smaller；Obstacle
The distance between thing and sensor are nearer, and sensor output voltage value is bigger；When CPU is detected between barrier and sensor
Distance is more than summation of the diameter plus distance between beans box and sensor of beans box（That is distance between A points and B points in Fig. 1）, coffee
Coffee machine points out to lack beans at once；When CPU detect the distance between barrier and sensor less than beans box diameter plus beans box with
The summation of distance between sensor（That is distance between A points and B points in Fig. 1）, coffee machine do not do the prompting of scarce beans.
Therefore, the present invention has advantages below：
（1）, the present invention scarce beans detection means can coffee machine work during in real time monitoring coffee machine beans box in whether
There is coffee bean；
（2）, the present invention scarce beans detection means compared with detecting scarce beans using tea infuser meter step number in the market, the present invention
Scarce beans detection scheme it is easy to implement, accuracy is high, will not because of the long beans that go down of the oiliness coffee bean used or standing time,
Occur pointing out by mistake；
（3）, the present invention scarce beans detection means compared with detecting scarce beans using tea infuser meter step number in the market, with brewing
Device meter step number detects scarce beans, when prompting lacks beans, and coffee machine system is directly to be discharged to the ground coffee wetting in tea infuser
In slag box, therefore the coffee machine coffee bean of the present invention lacks beans detection means saving coffee bean, saves user time, increase user's body
Test sense.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
