Description

Coffee machine

technical field

The utility model relates to the field of coffee machines, in particular to a coffee machine with a controllable heating module.

Background technique

There are different types of coffee, some of which are famous for their smooth milk foam, such as latte coffee, cappuccino coffee, au lait coffee, etc. The milk foam makes the taste richer and more mellow. However, after heating the coffee, the water outlet is about 92 degrees. If you want to froth the milk, the heating device needs to be heated to about 175 degrees before steam can be generated. Because of the temperature difference, the heating device needs to heat up and cool down. In addition to affecting the quality of coffee and frothing milk, the frequent heating and cooling of the heating device of a domestic coffee machine will also lead to changes in coffee quality and affect the quality of frothing milk, and it is inconvenient to use. Therefore, coffee machines and milk frothers currently on the market are usually two separate products to achieve their respective functions.

If both brewed coffee and frothed milk are added to one product, the heating module needs to switch between brewed coffee (lower temperature) and frothed milk (higher temperature), which is less efficient. If dual heating modules are used, although the efficiency can be improved, the working power of the dual heating modules is too high, which may exceed the maximum power limit of some countries and regions.

Therefore, need a kind of solution that can solve above-mentioned problem badly.

detailed description

Referring to Fig. 1, the utility model provides a coffee machine, which mainly includes: a water tank 100, a first heating module 200, a second heating module 300, a main control module 400, a power supply (not shown in the figure), a first temperature detection module ( not shown in the figure), the second temperature detection module (not shown in the figure), the hot water outlet 500, and the steam outlet 600. The first heating module 200 is used for brewing coffee, its input end is connected to the water tank through the first water pipe 210 , and the output end of the first heating module 200 is connected to the hot water outlet 500 . The second heating module 300 is used to generate steam for frothing milk. The input end of the second heating module 300 is connected to the water tank 100 through the second water pipe 310 , and the output end of the second heating module is connected to the steam outlet 600 .

In order to accurately measure the amount of coffee, a flow meter 700 is also connected between the water tank 100 and the first heating module 200 . A coffee pump 810 is also installed between the flow meter 700 and the first heating module 200 for blowing coffee, and a steam pump 820 is also installed between the water tank 100 and the second heating module 300 for blowing water for generating steam . The first heating module 200 and the steam pump 820 are respectively connected to the waste water basin 900 for discharging waste water.

Referring to FIG. 2 , the main control module 400 is used to control the heating state of the first heating module 200 and the second heating module 300 , specifically, in the start-up phase of the cold machine, alternatively start the first heating module and the second heating module, And disable the first heating module 200 and start the second heating module 300 when the temperature of the first heating module 200 rises to the first preset value; disable when the temperature of the second heating module 300 rises to the second preset value The second heating module 300 and the first heating module 200 are activated. Thus, the temperature of the first heating module 200 and the second heating module 300 can be quickly raised to the working state.

In this embodiment, the first preset value is the working temperature of the first heating module, and the second preset value is the working temperature of the second heating module. The modules are individually warmed up to their own operating temperature. In an alternative embodiment, the first heating module and the second heating module can reach their respective operating temperatures after two or more activation and deactivation cycles, that is, the first heating module 200 is heated up to the first First temporarily disable and enable the second heating module at the preset value, temporarily disable and start the first heating module when the temperature of the second heating module rises to the second preset value, and when the temperature of the first heating module 200 rises to the third preset value Temporarily disable and enable the second heating module first, and repeat this several times until the two heating modules respectively reach their own working temperatures.

The first temperature detection module is used to detect the temperature of the first heating module 200 and feed it back to the main control module 400 , and the second temperature detection module is used to detect the temperature of the second heating module 300 and feed it back to the main control module 400 . The main control module 400 activates/disables the first heating module 200 and the second heating module 300 through a switch circuit. In this embodiment, a relay is used as a switch.

The main control module 400 activates or disables the first heating module 200 and activates or disables the second heating module 300 through the second relay 430 . At the same time, the first relay 420 and the second relay 430 are also connected through the third relay 440, which is used to alternatively connect the first relay 420 and the second relay 430 in series with the first relay 420 and the second relay 430 to prevent the first heating module from 200 and the second heating module are heated simultaneously.

With reference to Fig. 3, a kind of coffee making method provided by the utility model comprises steps:

S101 Start one of the first heating module for heating coffee and the second heating module for frothing milk;

S103 detecting the temperature of the activated heating module;

S105 Disable the first heating module and start the second heating module when the temperature of the first heating module rises to a first preset value, and activate the second heating module when the temperature of the second heating module rises to a second preset value value disables the second heating module and activates the first heating module.

During specific implementation, when the coffee machine is not started, after starting the coffee machine, start the first heating module 200 to brew coffee, when the temperature of the first heating module 200 reaches the first preset value, disable the first heating module 200, and at the same time The second heating module 300 is enabled to generate steam, and when the temperature of the second heating module 300 reaches a second preset value, the second heating module 300 is disabled and the first heating module 200 is enabled. As mentioned above, in this embodiment, step S105 is executed once, and the first heating module and the second heating module respectively reach their working temperatures. In an alternative embodiment, step S105 is performed two or more times before the first heating module and the second heating module respectively reach their working temperatures.

Of course, it should be understood that when the temperature of the first heating module reaches the first preset value, whether the main control module turns on the second relay 430 depends on the type of coffee being brewed. The type of bubble naturally does not need to turn on the second relay when the temperature of the first heating module 200 reaches the first preset value, but only after the temperature of the first heating module 200 reaches the first preset value and the coffee flows out from the hot water outlet 500 ; Similarly, when the temperature of the second heating module reaches the second preset value, the first relay 420 must not be turned on. Whether the first relay 420 is turned on depends on whether it is necessary to brew and heat coffee. If only a cup of coffee is made In this case, when the temperature of the second heating module 300 reaches the second preset value, coffee flows out from the hot water outlet 500 , and steam is ejected from the steam outlet 600 , the power supply can be disconnected. The heating power of the first heating module 200 is smaller than that of the second heating module 300 . In this embodiment, the heating power of the first heating module 200 is 1100W and the heating power of the second heating module 300 is 1400W.

In order to prevent the main control module from sending an erroneous command to heat the first heating module and the second heating module at the same time, the third relay alternatively connects the first relay and the second relay in series, and the third relay controls the first relay and the second relay At least one of them is disconnected.

After the coffee machine has been started, the coffee machine provided by the utility model also has a standby mode. In the standby mode, the temperature of the first heating module and the second heating module is kept at a value that is easy to heat up, so as to start making coffee at any time. Specifically, in the standby mode, when the temperature of the first heating module 200 drops to the third preset value, the second heating module 300 is disabled and the first heating module 200 is activated, and when the temperature of the second heating module 300 drops to the third preset value, the second heating module 300 is disabled. At four preset values, the first heating module 200 is disabled and the second heating module 300 is activated. In this way, both the first heating module and the second heating module can be kept at their standby temperatures, and the total power will not be greater than the maximum power of the power supply circuit.

The preferred embodiment of the utility model has been described above with reference to the accompanying drawings. Those skilled in the art can realize the utility model in various variants without departing from the scope and essence of the utility model. For example, features illustrated or described as part of one embodiment can be used on another embodiment to yield a still further embodiment. The above are only preferred and feasible embodiments of the present utility model, and are not intended to limit the scope of rights of the present utility model.
