Description

Technical Field

[0001] This utility model relates to the field of machine technology, specifically to a coffee machine with temperature control function. Background Technology

[0002] With the fast pace of work and improved living standards, people often brew a cup of coffee to relieve work pressure and eliminate fatigue. Currently, coffee machines have gradually entered modern households as a common home appliance, making it more convenient for people to brew their own coffee. Furthermore, because coffee machines use boiling water to brew the coffee, it dissolves evenly, resulting in a purer taste and better flavor.

[0003] The coffee-making process is easily affected by external environmental factors (such as voltage fluctuations and room temperature changes), leading to significant fluctuations in water temperature. This results in unstable water temperature during extraction, affecting the taste and quality of the coffee. For example, the heating effect of a coffee machine can vary in different seasons or under different usage conditions, making it difficult to guarantee a consistent taste for every brew.

[0004] Therefore, a method was designed that uses steam to heat the brewed coffee liquid, and at the same time uses steam to warm the cup. The steam from the warmed cup is then used to froth milk and other mixed liquids. The frothing process is controlled by a solenoid valve to extract the appropriate proportion of the mixture into a temperature-regulating tank for heating and temperature adjustment, so that coffee can be enjoyed at the appropriate temperature in different environments. Utility Model Content

[0005] The purpose of this invention is to provide a coffee machine with temperature control function to solve the problems mentioned in the background art. The steam inside the water tank can not only brew coffee at the same time, but also controllably reheat the brewed coffee liquid, so as to achieve a suitable temperature for drinking coffee in different environments and improve the coffee drinking experience.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A coffee machine with temperature control function, comprising a coffee machine body and a water cup B. A water jet head is installed at the output end of the coffee machine body, and an extraction head adapted to the water jet head is installed at one end of the water jet head. A water storage tank is provided inside the coffee machine body, and a gas valve is installed at one end of the water storage tank. One side of the gas valve is connected to a pipe A, and the other end of pipe A is fixedly connected to a solenoid valve A that controls the steam flow direction. One side of the solenoid valve A is connected to a pipe B, and the other end of pipe B is connected through a temperature control tank. One end of the solenoid valve A is fixedly connected to a pipe C, and the pipe C... The other end of the pipe is connected to a spiral heating tube, and the other end of the heating tube is connected to a pipe D. A solenoid valve B is installed on the pipe D to control the flow of steam. The other end of the pipe D is connected to a steam pipe. A water cup A is placed below the steam pipe. A solenoid valve C is installed above the water cup A to control the steam pipe to draw liquid from inside the water cup A. One end of the solenoid valve C is connected to a pipe E. The other end of the pipe E is connected to a temperature control tank. The liquid drawn by the steam pipe flows into the temperature control tank through the pipe E and mixes. The solenoid valve B controls the steam in the pipe D to be discharged through the steam pipe. The steam discharged from the steam pipe then agitates the liquid inside the water cup A.

[0007] Optionally, the extraction head is snapped between the flushing head and the temperature control tank, and the temperature control tank is equipped with a temperature display.

[0008] Optionally, pipe E and pipe B are respectively connected to the interior of the temperature control tank, with pipe B located at the lower end of the temperature control tank and pipe E located at the upper end of the temperature control tank.

[0009] Optionally, the water cup B is placed horizontally and centered with the outlet of the temperature control tank, and the outlet of the temperature control tank is equipped with a control valve.

[0010] Optionally, the steam pipe is connected to both pipe D and pipe E.

[0011] Optionally, the heating element is wrapped around the outside of the water cup B.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The ground coffee powder is placed inside the extraction head, which is then engaged between the water inlet and the thermostat. When the coffee machine is turned on, water discharged from the machine flows through the water inlet, squeezing the coffee powder inside the extraction head, and then flows into the thermostat, thus achieving temperature control and enhancing the user experience. During temperature control, the steam pressure generated inside the water tank is controlled by a valve. One side of the valve is connected to pipe A, and the other end of pipe A is fixedly connected to a solenoid valve A that controls the steam flow. Solenoid valve A controls the steam flow, and then steam is delivered through pipe B connected to one side of solenoid valve A to heat the inside of the thermostat. This ensures that the steam inside the water tank not only brews the coffee but also provides controllable secondary heating to the brewed coffee, allowing for a suitable temperature to be enjoyed in different environments, thus improving the coffee-drinking experience.

[0014] 2. During the blending and heating of coffee, the temperature of the liquid inside cup A is unstable. At this time, the solenoid valve C controls the switch, and the steam pipe draws the liquid from inside cup A. The liquid then flows into the temperature control tank through pipe E for heating and temperature control. When the liquid inside the temperature control tank reaches the regulated temperature, it is discharged from the bottom of the temperature control tank into cup A for the consumer to enjoy. This avoids lowering the coffee temperature when adding liquid from cup A, thus preventing unstable temperature after blending from affecting the coffee's taste. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 6 This utility model provides a coffee machine with temperature control function. The coffee machine body 1 has a water jet head 2 installed at its output end. An extraction head 3, adapted to the water jet head 2, is installed at one end of the water jet head 2. The coffee machine body 1 has a water tank 4 inside. A gas valve 5 is installed at one end of the water tank 4. A pipe A7 is connected to one side of the gas valve 5. A solenoid valve A8, controlling the steam flow, is fixedly connected to the other end of the pipe A7. A pipe B9 is connected to one side of the solenoid valve A8. A temperature control tank 10 is connected to the other end of the pipe B9. A pipe C11 is fixedly connected to one end of the solenoid valve A8. A spiral heating element 6 is connected to the other end of the heating element 6. Pipe D12 is equipped with a solenoid valve B13 that controls the flow of steam. The other end of pipe D12 is connected to a steam pipe 14. A water cup A15 is placed below the steam pipe 14. A solenoid valve C16 is installed above the water cup A15 to control the steam pipe 14 to draw liquid from the inside of the water cup A15. One end of the solenoid valve C16 is connected to pipe E17. The other end of pipe E17 is connected to the temperature control tank 10. The liquid drawn through the steam pipe 14 flows into the temperature control tank 10 through pipe E17 and mixes. The solenoid valve B13 controls the steam in pipe D12 to be discharged through the steam pipe 14. The steam discharged from the steam pipe 14 then agitates the liquid inside the water cup A15.

[0024] Place the ground coffee powder inside the extraction head 3, and engage it between the water inlet head 2 and the temperature control tank 10. Start the coffee machine 1. At this time, the water discharged from the coffee machine 1 flows out through the water inlet head 2, squeezing the coffee powder inside the extraction head 3, and then flows into the temperature control tank 10, thereby achieving temperature controllability and enhancing the user's experience.

[0025] When controlling the temperature of coffee, the steam pressure generated inside the water tank 4 is controlled by the steam valve 5 to control the steam output. One side of the steam valve 5 is connected to the pipe A7, and the other end of the pipe A7 is fixedly connected to the solenoid valve A8 to control the steam flow direction. At this time, the solenoid valve A8 controls the steam flow direction, and then the steam is delivered to the interior of the temperature regulating tank 10 through the pipe B9 connected to one side of the solenoid valve A8. Thus, the steam inside the water tank 4 can not only brew coffee at the same time, but also controllably reheat the brewed coffee liquid, so as to achieve a suitable temperature for drinking in different environments and improve the coffee drinking experience.

[0026] When warming the coffee cup, the flow of steam is controlled by solenoid valve A8 and then flows into the interior of heating tube 6 through pipe C11. The temperature generated inside heating tube 6 then warms the cup B18, thus achieving the effect of warming the cup while controlling the temperature of the coffee, thereby reducing the impact of weather on the coffee cooling down and improving the taste of the coffee.

[0027] When steaming the liquid inside the water cup A15, the other end of the heating tube 6 is connected to the pipe D12. The pipe D12 is equipped with a solenoid valve B13 to control the flow direction. At this time, the solenoid valve B13 controls the steam flow direction to steam the liquid inside the water cup A15 through the steam pipe 14. This achieves the effect of controlling the steam to warm the cup and controlling the steam to steam the liquid inside the water cup A15, thereby achieving the effect of secondary energy utilization.

[0028] During the mixing and heating of coffee, the liquid temperature inside cup A15 is unstable. At this time, the solenoid valve C16 controls the switch, and the steam pipe 14 draws the liquid from inside cup A15. The liquid then flows into the temperature regulating tank 10 through pipe E17 for heating and temperature control. When the liquid inside the temperature regulating tank 10 is mixed to the regulated temperature, it is discharged into cup A15 through the bottom of the temperature regulating tank 10 for the consumer to enjoy. This avoids lowering the coffee temperature when adding liquid to cup A15, thus improving the consumer's coffee experience.

[0029] Working principle: Ground coffee powder is placed inside the extraction head 3. The coffee machine body 1 is started. Water discharged from the machine body 1 flows out through the water jet head 2, squeezing the coffee powder inside the extraction head 3, and then flows into the temperature control tank 10. During coffee temperature control, the steam pressure generated inside the water tank 4 is controlled by the steam valve 5. At the same time, the solenoid valve A8 controls the steam flow direction, and steam is then delivered through pipe B9 connected to one side of the solenoid valve A8 to heat the interior of the temperature control tank 10. When warming the coffee cup, the solenoid valve A8 controls the steam flow direction, and steam flows through pipe C11 into the heating element 6. Inside, the temperature generated inside the heating element 6 warms the water cup B18. While frothing the liquid inside the water cup A15, the solenoid valve B13 controls the steam flow through the steam pipe 14 to froth the liquid inside the water cup A15. When mixing and heating the coffee, since the temperature of the liquid inside the water cup A15 is unstable, the solenoid valve C16 controls the switch, and the steam pipe 14 draws the liquid from the water cup A15, which then flows into the temperature regulating tank 10 through the pipe E17 for heating and temperature control. When the liquid inside the temperature regulating tank 10 is mixed to the regulated temperature, it is discharged into the water cup A15 through the bottom of the temperature regulating tank 10 for the consumer to enjoy.
