Description
Technical Field
[0001] The utility model relates to the technical field of coffee machines, in particular to a coffee machine with a milk foam mixing and heating system. Background Art
[0002] People have applied electronic technology to coffee machines, realizing automatic control of the entire process of brewing coffee, including grinding, pressing, filling, brewing, and removing residues. They have created coffee machines that can brew coffee more conveniently, making it easier for people to drink coffee.
[0003] At present, traditional semi-automatic coffee machines only have steam rods, and milk foam needs to be frothed manually. The operation requires a professional barista, which is not only time-consuming but also has relatively high labor costs. Fully automatic coffee machines have automatic milk frothing systems, but the milk froth is heated by steam or electricity. The temperature of the steam-heated milk froth is unstable due to the influence of steam temperature and steam volume, air temperature and milk temperature. The milk froth produced by electric heating is relatively dry and has poor fluidity because there is no steam injection during the production process. Utility Model Content
[0004] The utility model aims to provide a coffee machine with a milk froth mixing and heating system, so as to solve the problem that old-fashioned coffee machines require manual milk frothing, which avoids the need for professional baristas to operate the machine, which is not only time-consuming but also has relatively high labor costs. In addition, although existing fully automatic coffee machines have automatic milk frothing systems, the milk froth is heated by steam or electricity. Due to the influence of steam temperature and steam volume, air temperature and milk temperature, the temperature of the milk froth produced is unstable. In addition, the milk froth produced by electric heating is relatively dry and has poor fluidity because no steam is injected during the production process.
[0005] To achieve the above objectives, a coffee machine with a milk froth mixing and heating system is provided, comprising a base, four rubber blocks for support fixedly connected to the bottom end of the base, a coffee machine body fixedly connected to the top end of the base, and a coffee buffer outlet, a milk buffer outlet, and a water outlet fixedly connected to the outside of the coffee machine body. A cavity is defined inside the coffee machine body through a partition, and a milk froth heating system is formed inside the cavity, which is sequentially provided with a liquid inlet joint, a mixing joint, a milk pump, a one-way valve, a milk froth steam mixer, a heating plate, and a liquid outflow head.
[0006] As a further improvement of the present technical solution, all components in the milk froth heating system are interconnected through connecting pipes, and all components in the milk froth heating system are fixed to the partition by screws.
[0007] As a further improvement of the present technical solution, three inlets and outlets are provided on the outside of the liquid inlet joint and the liquid outlet head, and the three inlets and outlets are arranged as a clean water inlet and outlet, a connecting port and a milk inlet and outlet from top to bottom.
[0008] As a further improvement of the present technical solution, the clean water outlet in the liquid outflow head is connected to the water outlet, and the milk outlet in the liquid outflow head is connected to the milk buffer outlet.
[0009] As a further improvement of the present technical solution, a temperature detection head is provided inside the heating plate.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] This coffee machine with a milk froth mixing and heating system heats the milk evenly by passing the whipped milk into the milk froth mixer together with the steam, while reducing the pulse effect caused by unstable steam. The mixed milk froth reaches an approximate temperature and enters the heating plate for secondary heating. Since the heating plate uses a built-in temperature sensor, the power of the heating plate can be accurately controlled according to the algorithm, so that the milk froth finally reaches the precise required temperature. At the same time, due to the injection of steam, the smoothness of the milk froth is the same as that made by traditional baristas manually. In the end, high-quality milk froth with precise temperature and high smoothness is obtained, making coffee containing milk froth simpler and more standardized. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.
[0022] See also Figures 1-6 As shown, the embodiment of the present invention provides a coffee machine with a milk foam mixing and heating system, which includes the following solutions:
[0023] Specifically, it includes a base 1, the bottom end of which is fixedly connected to four rubber blocks for support, the top end of which is fixedly connected to a coffee machine body 2, and also includes a coffee buffer outlet 3, a milk buffer outlet 4 and a water outlet 5 fixedly connected to the outside of the coffee machine body 2. A cavity 7 is opened inside the coffee machine body 2 through a partition 6. The milk froth heating system formed inside the cavity 7 is sequentially provided with a liquid inlet joint 8, a mixing joint 9, a milk pump 10, a one-way valve 11, a milk froth steam mixer 12, a heating plate 13 and a liquid outflow head 14; all components in the milk froth heating system are interconnected through connecting pipes, and all components in the milk froth heating system are fixed to the partition 6 by screws.
[0024] In the above technical solution, before starting, milk is first introduced into the milk inlet of the liquid inlet joint 8 through the connection of the pipe, and then transported from the connection port 16 of the liquid inlet joint 8 to the mixing joint 9 containing air inside. At this time, the milk containing air is transported to the milk pump 10 located above the mixing joint 9. The milk pump 10 pressurizes the milk containing air and transports it to the milk frothing steam mixer 12 through the one-way valve 11. Then, the steam solenoid valve controls an appropriate amount of steam to enter the milk frothing steam mixer 12, so that the milk can be heated evenly. At the same time, the air inside the milk is pressurized by the high-temperature steam and finally forms milk foam with the milk. The mixed milk foam reaches an approximate temperature and enters the heating plate 13 for secondary heating. Finally, the formed milk foam is transported from the heating plate 13 to the liquid outflow head 14 and flows into the milk buffer outlet 4 from the milk outlet of the liquid outflow head 14. At this time, the milk can be opened through the control screen on the coffee machine body 2 to open the milk buffer outlet 4 and be poured into the cup.
[0025] Specifically, three inlets and outlets are provided on the outside of the liquid inlet joint 8 and the liquid outlet head 14, which are arranged from top to bottom as a clean water inlet and outlet 15, a connecting port 16 and a milk inlet and outlet 17; the clean water outlet in the liquid outlet head 14 is connected to the water outlet 5, and the milk outlet in the liquid outlet head 14 is connected to the milk buffer outlet 4.
[0026] The above technical solution separates the entrance and exit of the milk channel and the clean water channel, which can avoid the mixing of clean water and milk, thereby affecting the quality of milk foam and the taste of milk coffee.
[0027] Specifically, a temperature detection head 18 is provided inside the heating plate 13 .
[0028] The above technical solution uses a built-in temperature sensor in the heating plate 13 to accurately control the power of the heating plate 13 according to an algorithm, so that the milk foam finally reaches the precisely required temperature.
[0029] Working principle: First, connect the various components in the milk foam heating system through pipes to form a semi-closed connection channel, then let the milk enter from the milk inlet of the liquid inlet joint 8 through the connection of the pipe, and then transport it to the mixing joint 9 equipped with an air component from the connection port 16 of the liquid inlet joint 8. At this time, some air is mixed in the milk and transported together to the milk pump 10 located above the mixing joint 9. The milk pump 10 pressurizes the milk containing air and transports it to the milk foam steam mixer 12 through the one-way valve 11. Then, the steam solenoid valve controls the appropriate amount of steam to enter the milk foam steam mixer 12, so that the milk can be heated evenly. At the same time, the air inside the milk is pressurized by the high-temperature steam and finally forms milk foam with the milk. The combined milk foam reaches an approximate temperature and enters the heating plate 13 for secondary heating. Since the heating plate 13 uses a built-in temperature sensor, the power of the heating plate 13 can be accurately controlled according to the algorithm, so that the milk foam finally reaches the precise required temperature. At the same time, due to the injection of steam, the smoothness of the milk foam is the same as that made by traditional baristas manually. In this way, high-quality milk foam with precise temperature and high smoothness is finally obtained, making the preparation of coffee containing milk foam simpler and more standard. The finally formed milk foam is transported from the heating plate 13 to the liquid outflow head 14, and flows into the milk buffer outlet 4 from the milk outlet of the liquid outflow head 14. At this time, the milk can be opened through the milk buffer outlet 4 through the control screen on the coffee machine body 2 and connected to the cup.
