Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to an all-in-one coffee purifier and drinker. Background Art

[0002] At present, there are only independent built-in coffee machines and water purifiers on the market. The water purifier only has the function of purifying water, while the coffee machine usually uses a water tank and needs to add purified water frequently to meet the requirements of coffee making and self-cleaning.

[0003] In order to integrate the functions of water purifiers and coffee machines, people have developed all-in-one water purifiers and coffee machines. For example, the Chinese patent "A composite water purifier" with patent application number CN202021615481.4 uses a combined structural design on the back cover structure, cooperates with the main bracket structure, and integrates a coffee machine, forming a composite water purifier that can be used for both water purification and water purification to meet the multi-functional needs of users.

[0004] However, for existing all-in-one coffee machines, one water pump is used to make coffee and froth milk. The life of a water pump is generally 250 hours. When used by multiple people or in an office, the life is shorter. When the frequency of use is too high, the water pump is prone to overheating or damage, which affects its service life. The current common solution is to directly install two water pumps and turn them on in turn, which increases costs. Utility Model Content

[0039] The working principle of this embodiment is as follows:

[0040] (1) Normal temperature water: The booster pump 113 is started, the solenoid valve a1 is closed, the solenoid valve a2 is opened, and the tap water is filtered through multiple layers and flows out from the direct drinking port 41 of the liquid outlet system 4;

[0041] (2) Hot water: The booster pump 113 is started, the solenoid valve a1 is opened, and the solenoid valve a2 is closed. The tap water is filtered through multiple layers and stored in the pressure buffer 13. The DC pump 1411 is started, the solenoid valve b1 is opened, and the solenoid valve b2 is closed. The water in the pressure buffer 13 enters the heater 14 through the first pipeline 141 and is heated to a specified temperature. The water then flows out from the direct drinking port 41 of the liquid outlet system 4.

[0042] (3) Coffee: The booster pump 113 is started, the solenoid valve a1 is opened, the solenoid valve a2 is closed, the tap water is filtered through multiple layers and stored in the pressure buffer 13; the vibration pump 2111 is started, the solenoid valve b3 is opened, the solenoid valve b4 is closed, the water in the pressure buffer 13 enters the heating block 21 through the second pipeline 211, is heated, and then enters the brewing device 22 to make coffee, and flows out from the coffee port 42 of the liquid outlet system 4;

[0043] (4) Milk froth: the booster pump 113 is started, the solenoid valve a1 is opened, the solenoid valve a2 is closed, the tap water is filtered through multiple layers and stored in the pressure buffer 13; the DC pump 1411 is started, the solenoid valve b1 is closed, the solenoid valve b2 is opened, the solenoid valve b3 is closed, and the solenoid valve b4 is opened. The water in the pressure buffer 13 enters the heating block 21 through the first pipeline 141 and the third pipeline 212 in sequence to be heated and prepared into steam and enter the milk froth system 3. The milk froth system 3 sucks in milk and generates milk froth through the Venturi principle, and flows out from the milk froth port 43 of the liquid outlet system 4;

[0044] (5) Drainage: Wastewater from the water receiving tray 52, concentrated water from the filter module 11, water in the pressure buffer 13 that has not been used for a long time, and cooling water from the heating block 21 are collected in the drain port 51 and flow out from the drain pipe by gravity.

[0045] In the present invention, when making white coffee, the brewing water comes directly from the vibration pump 2111, and when making milk coffee for frothing milk, the water comes from the DC pump 1411. The two water paths are directly separated, thereby extending the life of the water pump (because the brewing pressure requirement for coffee is relatively high and must be stable at 9 bar, the vibration pump 2111 can provide high pressure, but when making milk frothing, the pressure requirement is relatively low, about 4 bar, and the DC pump 1411 is completely sufficient), so the combination of the water purification system 1 and the coffee system 2 can achieve separate control of the coffee pump and the milk frothing pump, thereby extending the life of the water pump.
