Description

Milk foaming machine and corresponding coffee machine

Technical Field

The utility model relates to a milk foaming preparation technical field specifically indicates a milk foaming machine and corresponding full-automatic coffee machine milk bubble function.

Background

The milk frother which is common on the market at present is a steam milk frother device which is attached to an automatic coffee machine. The device directly blows out the milk by using steam and simultaneously sucks the milk by using siphon of the steam. The disadvantage is that the milk foam with uniform and dense bubbles can not be made. The uniform and dense bubbles of the milk foam are the necessary precondition for the coffee maker to flower.

Therefore, there is a need for a milk frother that can produce a uniform, dense milk froth.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a milk foaming machine that can produce even continuous cold, hot milk foam to prior art not enough.

In order to achieve the above purpose, the technical scheme of the milk foaming machine of the utility model is as follows: the milk foaming machine comprises a conveying pump, wherein an inlet end of the conveying pump is respectively connected with an air pipeline, a milk pipeline and a cleaning water pipeline, an outlet end of the conveying pump is sequentially provided with a first electromagnetic valve and a second electromagnetic valve, a cold milk foam pipeline and a hot milk foam pipeline are arranged between the first electromagnetic valve and the second electromagnetic valve, the hot milk foam pipeline is provided with a heater, the second electromagnetic valve is provided with a milk foam outlet leading to a container and a drainage outlet leading to a waste water pipe, and a flow limiting hole is arranged between the outlet end of the conveying pump and the first electromagnetic valve to limit the flow speed of the outlet end of the conveying pump so as to utilize the conveying pump to mix milk and air into milk foam.

Preferably, the air pipeline is provided with a third electromagnetic valve for controlling the time and the flow of air.

Preferably, the milk pipeline is provided with a fourth electromagnetic valve for controlling the time and the flow rate of the milk.

Preferably, the washing water pipeline is provided with a fifth electromagnetic valve for controlling the time and flow rate of the washing water.

Preferably, the second electromagnetic valve is a three-way electromagnetic valve.

Preferably, the diameter of the flow limiting hole is 0.5-1 mm.

Preferably, the delivery pump is a gear pump, so that the milk and the air are mixed into the milk foam by using the gear of the delivery pump.

The utility model also provides a coffee machine, coffee machine in the milk bubble system use the milk foaming machine.

Adopted the utility model discloses a milk foaming machine can control milk foaming machine through the singlechip of intelligence and obtain hot, cold milk bubble, when being applied to the coffee machine, can also control the parcel and milk bubble many with few, milk bubble stability of quality is higher, has the quality and the heating efficiency that can not make out by hand.

Detailed Description

In order to clearly describe the technical content of the present invention, the following further description is made in conjunction with specific embodiments.

As shown in fig. 1, which is a specific embodiment of the milk frother of the present invention, wherein the milk frother comprises a delivery pump 1, the inlet end of the delivery pump is respectively connected with an air pipeline 2, a milk pipeline 3 and a cleaning water pipeline 4, the outlet end of the delivery pump is sequentially provided with a first electromagnetic valve 5 and a second electromagnetic valve 6, a cold milk foam pipeline 7 and a hot milk foam pipeline 8 are arranged between the first electromagnetic valve and the second electromagnetic valve, the first electromagnetic valve 5 is used for switching cold and hot milk foam, the hot milk foam pipeline is provided with a heater 9, the second electromagnetic valve is provided with a milk foam outlet 10 leading to the container and a drainage outlet 11 leading to a waste water pipe, a flow limiting hole is arranged between the outlet end of the delivery pump and the first electromagnetic valve, to limit the flow rate at the outlet end of the delivery pump so that milk and air are mixed into a milk foam by the delivery pump.

The utility model discloses an outlet end of delivery pump installs the current-limiting aperture additional, and the velocity of flow that the current-limiting aperture can greatly reduced delivery pump export will stop a period like this with the air in the delivery pump, and the high rotational speed gear of delivery pump can mix milk and air into milk foam to utilize the pressure that the delivery pump produced to discharge again after evenly sneaking into milk with the air and becoming milk foam. Generally, the diameter of the flow limiting hole is 0.5-1 mm. The heater 9 may use a heater based on a heat exchange principle. The delivery pump is a gear pump, so that milk and air are mixed into milk foam by utilizing the gear of the delivery pump.

Wherein, the heater is opened when hot milk foam needs to be made, and the first solenoid valve 5 controls the cold milk foam that just goes out of the delivery pump to pass through the heater, and what just so come out is hot milk foam.

As shown in fig. 1, the air pipeline is provided with a third electromagnetic valve for controlling the time and flow rate of air entering; the milk pipeline is provided with a fourth electromagnetic valve for controlling the time and flow of milk; the washing water pipeline is provided with a fifth electromagnetic valve for controlling the time and flow of the washing water.

The second solenoid valve be three solenoid valve for control flows out milk foam or washs water, second solenoid valve 6 opens and leads to the milk jar when preparation milk foam, and during the washing pipeline, second solenoid valve 6 closes in order to lead to the drain pipe.

In this specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
