Drawings
Fig. 1 is a block diagram illustrating a drainage system of a fully automatic coffee maker according to the present invention.
In the figure: 1 water tank, 2 external water sources, 3 preparation units, 4 water discharge pipes, 5 coffee output ports, 6 by-pass valve pipes, 7 outlets, 8 controllable valves, 9 delivery pumps, 10 flow meters and 11 anti-backflow valves.
Detailed Description
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings to fully understand the objects, the features and the effects of the present invention.
Example (b):
as shown in fig. 1, the drainage system of the full automatic coffee machine of the present invention includes a control unit, a water tank 1, a preparation unit 3, and a drainage pipe 4, wherein the water tank 1 is communicated with an external water source 2, and supplies water for preparing coffee beverage to the water tank 1; the water tank 1 communicates with a preparation unit 3 for preparing a coffee water supply.
The waste water generated by the preparation unit 3 is discharged through a drain pipe 4; the preparation unit 3 is provided with a coffee outlet 5 for outputting a coffee beverage which can be accessed for consumption by a suitable beverage container cup.
Downstream of the water tank 1 and upstream of the preparation unit 3, a controllable valve 8 is provided; a bypass valve pipe 6 is communicated with the controllable valve 8, an outlet 7 of the bypass valve pipe 6 is communicated with the drain pipe 4, and the outlet 7 is as close to the preparation unit 3 as possible so as to capture the maximum residual water pollution part of the drain pipe 4; the bypass valve pipe 6 is provided with a delivery pump 9.
The drain pipe 4 is provided with a flow meter 10.
The drain pipe 4 is provided with an anti-return valve 11.
The control unit is used for controlling the preparation unit 3, the controllable valve 8, the delivery pump 9, the flow meter 10 and the anti-reflux valve 11.
The operation method of the drainage system of the full-automatic coffee machine comprises the following steps:
in a normal state, the controllable valve 8 is in a state of communicating the water tank 1 with the preparation unit 3, and the water tank 1 is connected with purified water through the external water source 2 and sent to the preparation unit 3; the residual water of the preparation unit 3 is discharged through a drain pipe 4;
when the residual water falls below the threshold value within a fully defined period of time, the flow meter 10 sends a signal to the control unit which switches the controllable valve 8 into a state in which it communicates the water tank 1 with the bypass valve pipe 6;
thereby flushing the water discharge pipe 4 with the purified water of the water tank 1; after the flushing is completed, the control unit controls the controllable valve 8 to switch to a state in which the water tank 1 and the preparation unit 3 are communicated.
The time period, the threshold value and the time parameter for the flushing are preset in the control unit, which closes the bypass valve duct 6 via the controllable valve 8 (i.e. the controllable valve 8 is switched to a state in which the water reservoir 1 and the preparation unit 3 are in communication) as soon as a sufficient volume flow is detected by the flow meter 10, so that the preparation unit 3 can be used again for preparing a coffee beverage. Thus, the monitoring and cleaning of the sewage discharge inside the discharge pipe 4 can be handled completely automatically and without any intervention by the user of the fully automatic coffee machine, providing a high degree of convenience.
When the drain pipe 4 is flushed with clean water from the water tank 1, the feed pump 9 is activated by the control unit to increase the pressure additionally, so that stubborn deposits can be reliably removed; the anti-return valve 12 ensures that the waste water does not return during water flushing, in particular during use of the delivery pump 9, unintentionally into the preparation unit 3.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
