Embodiment 1

[0019] Embodiment 1, as shown in Figure 1, a multifunctional coffee machine includes a water tank 1, and an electromagnetic pump 2 with adjustable flow is connected under the water tank 1, and the electromagnetic pump 2 can realize corresponding An electromagnetic pump with two different flow states for producing hot water for making coffee or producing steam. The outlet of the electromagnetic pump 2 is connected to the heating switching assembly 3 that heats the water in the water tank 1 and switches the direction of water flow through a main channel. The outlet of the electromagnetic pump 2 can be connected to one end of the single water pipe electric heating pipe 6a through the main channel, and the other end of the single water pipe electric heating pipe 6a (that is, only one water flow channel, as shown in Figure 4) is connected to a two-position three-way switch that can switch the direction of water flow. Through the solenoid valve 7, one of the channels coming out of t...

Embodiment 2

[0020] Embodiment 2, as shown in FIG. 2 , is different from Embodiment 1 in that a bypass 11 connected to the water tank 1 is provided between the electromagnetic pump 2 and the heating switching assembly 3 , and the bypass 11 and the heating switching assembly 3 There is a one-way valve 8 that restricts the flow of water, and the other end of the one-way valve 8 is connected to the heating switching assembly 3 . Therefore, when the water supply of the electromagnetic pump 2 is greater than the water flow of the one-way valve 8, part of the water from the electromagnetic pump 2 will flow back to the water tank 1 through the bypass 11. The main purpose is to adjust the water flow and control the pressure of the water flow channel. , to overcome the defects of the water flow and the unstable pressure of the water flow channel that can exist in the first embodiment, so that the water flowing out of the one-way valve 8 is very stable.

Embodiment 3

[0021] Embodiment 3, as shown in FIG. 3 , is different from Embodiment 2 in that the heating switching assembly 3 includes a two-position three-way solenoid valve 7 and a double water pipe electric heating tube 6b (that is, there are two water flow channels, as shown in FIG. 5 As shown), the outlet of the electromagnetic pump 2 is connected to the two-position three-way solenoid valve 7 through the main channel, and the water pipe coming out of the two-position three-way solenoid valve 7 is connected to the double water pipe electric heating tube 6b with two water channels, and then The water flowing out from the double water pipe electric heating pipe 6b is respectively connected to the shower head 4 and the steam nozzle 5, the main purpose of which is to independently adjust and control the heating temperature of the two channels and improve the accuracy of temperature control.

Abstract

The invention discloses a multifunctional coffee machine, and in particular relates to a milk frothing coffee machine capable of boiling coffee and generating milk froth, which comprises a water tank (1) with a single water outlet; the lower part of the water tank (1) is connected with an electromagnetic pump (2) with adjustable flow rate; an outlet of the electromagnetic pump (2) with the adjustable flow rate is connected to a heating and switching component (3) capable of heating water in the water tank (1) and switching the water flow direction through a main passage; and one passage out of the heating and switching component (3) is connected to a shower head (4), and the other passage is connected to a steam nozzle (5). The multifunctional coffee machine is applied to markets, households, and the like.

Description

【Technical field】 [0001] The present invention relates to a multifunctional coffee machine, and furthermore, relates to a whipped coffee machine capable of brewing coffee and generating milk froth. 【Background technique】 [0002] At present, the existing milk coffee machine adopts a water tank with double water outlets and a heating system, at least with a first heating pipe. The heating system is connected with the water tank through the first connecting channel and the second connecting channel, the first connecting channel has a check valve (one-way valve), and the second connecting channel has a pump. The shower head is connected to the heating system through the pipeline, and the pipeline is connected to the shower head from the heating system; the steam outlet is connected to the heating system through the steam channel, that is to say, when the pump is in working state, the water tank is connected to the steam channel. The first connecting channel is used for brewing...
