[0002] The coffee machine uses electronic technology to realize automatic control of the entire process of brewing coffee, including grinding, pressing, filling, brewing, and removing residues.

[0003] There are several types of coffee: traditional coffee (American / Italian) and cold brew. Traditional coffee (American / Italian) requires hot water, so the water entering the coffee brewing module must be hot. Therefore, whether it's a semi-automatic or fully automatic coffee machine, the coffee that comes out of the water outlet is always hot. Cold brew coffee requires ice water, so the water entering the coffee brewing module must be ice cold.

[0004] When iced coffee is needed, additional ice cubes must be added to make it iced coffee. However, ice cubes are water. Adding ice cubes to coffee is actually a disguised way of adding water to dilute the concentration of coffee, affecting the taste.

[0005] Therefore, how to quickly turn hot coffee into iced coffee without adding ice cubes while providing ice water for cold brew coffee is one of the key tasks of those skilled in the art. Summary of the Invention

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] Please refer to Figure 1-Figure 3 , Figure 1A schematic structural diagram of an embodiment of a multi-channel solid-state temperature control module provided by the present invention; Figure 2 A schematic diagram of the flow channel structure of an embodiment of a multi-flow channel solid-state temperature adjustment module provided by the present invention; Figure 3 This is a schematic diagram of the connection structure of an embodiment of the coffee machine provided by the present invention.

[0026] In a specific embodiment, the multi-channel solid-state temperature control module 100 includes a casting body 10 for heat transfer, a first flow channel 20, a second flow channel 30, a third flow channel 40, a heating system 50, a cooling system 60 and a controller arranged in the casting body 10, wherein the first flow channel 20 is a normal temperature water flow channel for passing normal temperature water, the second flow channel 30 is connected to the cooling system 60 for passing a refrigerant, the heating system 50 is used to heat the coffee output by the coffee brewing module 70 to form hot coffee, and pass the hot coffee into the third flow channel 40, wherein the controller is used to control the third flow channel 40 to operate to produce a hot coffee beverage, the controller is also used to control the second flow channel 30 and the third flow channel 40 to operate simultaneously, cooling the hot coffee with the refrigerant to produce an iced coffee beverage, and the controller is also used to control the first flow channel 20, the second flow channel 30 and the third flow channel 40 to operate simultaneously, mixing the cooled normal temperature water with the cooled hot coffee to produce cold brew coffee.

[0027] By arranging a first flow channel 20, a second flow channel 30, and a third flow channel 40 in the cast body 10, the first flow channel 20 is used to pass in normal temperature water, the second flow channel 30 is connected to the refrigeration system 60 for passing in a refrigerant medium, and the third flow channel 40 is connected to the heating system 50. The heating system 50 heats the coffee output by the coffee brewing module 70 to form hot coffee, and passes the hot coffee into the third flow channel 40. The controller only controls the third flow channel 40 to work, which will produce an output hot coffee beverage. The second flow channel 30 and the third flow channel 40 are controlled to work at the same time, and the hot coffee is cooled by the refrigerant medium to produce an output iced coffee beverage. The first flow channel 20, the second flow channel 30 and the third flow channel 40 are controlled to work at the same time, and the cooled normal temperature water is mixed with the cooled hot coffee to generate cold brew coffee. The entire device can heat and cool at the same time without the need for additional hot and cold tanks. More functions can be achieved under the same volume, and the overall structure is simplified.

[0028] Since the present application mainly focuses on the temperature control of coffee, in order to further improve the precise control of the temperature of the output coffee, in one embodiment, the multi-channel solid-state temperature control module 100 also includes temperature sensors arranged at the inlet and outlet of the first flow channel 20, the inlet and outlet of the second flow channel 30, and the inlet and outlet of the third flow channel 40.

[0029] By setting temperature sensors at the input ports of the three flow channels respectively, the temperature information therein and the temperature information of the input and output materials can be obtained in real time, so that users can set subsequent heating power, cooling power and other information as needed, so that users can quickly obtain coffee at the required temperature and improve service efficiency.

[0030] This application does not limit the type, location, quantity, etc. of the temperature sensor.

[0031] In order to further improve management efficiency and enable users to directly obtain operating information of the equipment, in one embodiment, the multi-channel solid-state temperature control module 100 also includes a display connected to the controller, the first channel 20, the second channel 30, the third channel 40, the heating system 50, the cooling system 60 and the temperature sensor, for displaying the current operating mode of the controller, the first channel 20, the second channel 30, the third channel 40, as well as the heating power of the heating system 50, the cooling power of the cooling system 60, and the temperature value obtained by the temperature sensor.

[0032] The display can display the operating data of the equipment in real time, so that in the subsequent use process, the status can be controlled in real time according to its operating data to improve the operating efficiency of the equipment. Even in the subsequent operation process, the subsequent control efficiency can be improved by establishing a model based on the historical operating data.

[0033] This application does not limit the type, structure, and display mode of the display.

[0034] In the present application, a cast body 10 is used to fix and integrate various flow channels, which on the one hand plays a fixing role, and on the other hand can realize temperature transfer and improve cooling efficiency.

[0035] In order to further improve the heat conduction efficiency, in one embodiment, the casting body 10 is an aluminum casting body, a copper casting body or a copper-aluminum alloy casting body.

[0036] The material of the cast body 10 is not limited in this application, and includes but is not limited to the above-mentioned materials.

[0037] In the present application, since it is necessary to pass materials into and out of the first flow channel 20, the second flow channel 30, and the third flow channel 40, and heat conduction, cooling and other operations are required in this process, in order to facilitate the input and output of materials at different angles and meet different needs, in one embodiment, the outlet and inlet of the first flow channel 20, the second flow channel 30, and the third flow channel 40 are located on the same side or different sides of the casting body 10.

[0038] Moreover, the outlets and inlets of different flow channels can be set at different positions.

[0039] In order to facilitate the installation and use process and improve the installation efficiency and ease of use, in one embodiment, the multi-channel solid-state temperature control module 100 also includes channel inlet and outlet markings arranged on the casting body 10 for indicating the inlets and outlets of the first channel 20, the second channel 30, and the third channel 40.

[0040] By providing flow channel inlet and outlet markings on the cast body 10 to indicate the inlet and outlet of the first flow channel 20, the second flow channel 30, and the third flow channel 40, the corresponding material input and output positions can be directly obtained during installation and subsequent use, thereby improving the use effect.

[0041] The present application does not limit the type, structure and setting method of the flow channel entrance and exit markings, and they can also be implemented through numbers, colors, graphics and other markings.

[0042] In this application, there is no limitation on the size, shape, etc. of the first flow channel 20, the second flow channel 30, and the third flow channel 40. In order to improve installation efficiency, the first flow channel 20, the second flow channel 30, and the third flow channel 40 are generally of the same shape and equal size.

[0043] In order to increase the residence time and material capacity of the material per unit length, the first flow channel 20 , the second flow channel 30 , and the third flow channel 40 are spiral flow channels or V-shaped flow channels.

[0044] The spiral flow channel can store more substances, such as more coffee, cooling media, etc., and at the same time, it can make the substances flow continuously and output continuously after the flow is completed, thereby improving the sustainability of the equipment.

[0045] Figure 2 This is a structural diagram of the first flow channel 20 in an embodiment, wherein the outlet and inlet are both located at the lower end. After entering the upper end through the straight flow channel split from the inlet at the lower end, it is connected with the spiral flow channel split of the spiral structure at the upper end, and heat exchange is completed in the spiral flow channel split. By utilizing the structural characteristics of the spiral flow channel split, the storage amount of materials and the heat exchange efficiency can be increased.

[0046] In this application, since the first flow channel 20, the second flow channel 30, and the third flow channel 40 are mainly used to pass food, in order to improve thermal conductivity and safety of use, the first flow channel 20, the second flow channel 30, and the third flow channel 40 are food-grade stainless steel flow channels or copper flow channels, or flow channels made of other materials.

[0047] Since different flow channel structures have different entrance and exit structures, in order to facilitate the output of the prepared coffee to a designated location, in one embodiment, the multi-channel solid-state temperature control module 100 also includes an angle adjustment device provided on the casting body 10, and the angle adjustment device is used to control the angle between the coffee outlet of the casting body 10 and the coffee machine body according to the control instructions of the controller.

[0048] By means of the angle adjustment device, the angle between the coffee outlet of the casting body 10 and the main body of the coffee machine is controlled according to the control instructions of the controller, so that the angular position of the material input and output can be changed. For example, the material is input at the first position and the material is output at the second position, which can realize the automatic output of coffee and improve the convenience of use.

[0049] In one embodiment, the multi-channel solid-state temperature control module 100 includes a first channel 20 , a second channel 30 , a third channel 40 and an aluminum block casting.

[0050] The flow channel is made of stainless steel (food grade, though non-food grade stainless steel is acceptable if not intended for food heating). The coil length is designed to accommodate the required temperature variations. Through a casting process, the three stainless steel flow channels are fused tightly together with the aluminum block to form a single component with built-in piping.

[0051] Among them, the first flow channel 20 is a normal temperature water flow channel, the second flow channel 30 is a refrigerant flow channel, the third flow channel 40 is a coffee flow channel, and the aluminum block is a temperature transfer medium.

[0052] When the refrigeration system 60 is started, the refrigerant passes through the second flow channel 30, and the second flow channel 30 is used for heat transfer, which causes the temperature of the entire aluminum block to drop rapidly, and the entire aluminum block forms an evaporator.

[0053] The iced coffee production process is as follows: after hot water enters through the inlet of the third flow channel 40, it continuously exchanges heat with the low-temperature module while flowing in the flow channel, achieving rapid cooling, and then flows out of the outlet as warm water at a lower temperature (when the refrigeration system 60 is not working, the refrigerant in the second flow channel 30 stops flowing, and what comes out of the third flow channel 40 is hot coffee).

[0054] Therefore, the outlet of the third flow channel 40 can deliver hot coffee or iced coffee.

[0055] The room-temperature water is cooled to ice water, which becomes the source of cold brew coffee. After passing through the inlet of the first flow channel 20, the room-temperature water continuously exchanges heat with the low-temperature module as it flows through the flow channel, achieving rapid cooling and flowing out of the outlet as ice water.

[0056] Through this module, the third flow channel 40 can be realized to produce hot coffee, iced coffee, and cold brew coffee. At the same time, the first flow channel 20 can also provide ice water for making cold brew coffee, achieving functional diversity and simple structure.

[0057] In addition, an embodiment of the present application further provides a coffee machine, comprising the multi-channel solid-state temperature adjustment module 100 as described above.

[0058] Since the coffee machine includes the multi-channel solid-state temperature adjustment module 100 as described above, and has the same beneficial effects as the multi-channel solid-state temperature adjustment module 100 as described above, this application will not elaborate on this.

[0059] In summary, the multi-channel solid-state temperature control module and coffee machine provided by the embodiments of the present invention relate to the field of coffee temperature control technology. By arranging a first channel, a second channel, and a third channel in the cast body, the first channel is used to pass normal temperature water, the second channel is connected to the refrigeration system for passing a refrigerant medium, and the third channel is connected to the heating system. The heating system heats the coffee output by the coffee brewing module to form hot coffee, and passes the hot coffee into the third channel. The controller only controls the third channel to work to produce an output hot coffee beverage. Controlling the second and third channels to work at the same time, the hot coffee is cooled by the refrigerant medium to produce an output iced coffee beverage. Controlling the first, second, and third channels to work at the same time, the cooled normal temperature water and the cooled hot coffee are mixed to produce cold brew coffee. The entire device can heat and cool at the same time without the need for additional hot and cold tanks. Under the same volume, more functions are achieved, and the overall structure is simplified.

[0060] The above describes in detail the multi-channel solid-state temperature control module and coffee machine provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention.
