Description

Technical Field

[0001] This utility model relates to an ice drip coffee machine, and more particularly to an ice drip coffee machine that controls water flow, water level and temperature. Background Technology

[0002] In traditional cold drip coffee makers, the water flow rate is typically controlled by manually rotating a valve. To maintain a low temperature, ice is usually used as the water source. However, the dripping speed slows down or even stops completely while waiting for the ice to melt. This requires the user to constantly monitor and fine-tune the dripping speed, which is labor-intensive and can lead to uneven coffee extraction, affecting the overall flavor and quality of the coffee. Furthermore, traditional cold drip coffee makers lack water level control, making it easy for too much or too little water to be added during the coffee extraction process, ultimately affecting the extraction results. Moreover, the reliance on manual operation increases the risk of human error, resulting in inconsistent coffee quality each time.

[0003] Furthermore, the manual brewing process of cold drip coffee often lacks refrigeration facilities, and is mostly simply carried out at room temperature. During the long extraction process, the coffee liquid may deteriorate or lose its flavor due to the increased temperature, making it difficult to produce high-quality cold drip coffee. The cost and time involved also increase the price of cold drip coffee. The high price may make cold drip coffee a relatively niche beverage, limiting its market penetration and making it unaffordable for some consumers. This reduces the potential customer base and market demand, affecting its competitiveness in the coffee market. Utility Model Content

[0004] Based on the aforementioned deficiencies, the purpose of this invention is to provide an iced drip coffee machine that replaces traditional manual iced drip coffee making, effectively controlling the flow rate, volume, and temperature to stabilize the quality of the iced drip coffee. According to this invention, an iced drip coffee machine is provided, comprising a housing and a water supply device. The water supply device is disposed on the outer surface of the housing. The interior of the housing includes: at least one water outlet disposed on the inner top surface of the housing; a cold water container; at least one coffee container with its opening corresponding to the at least one water outlet; and at least one liquid level sensor disposed adjacent to the at least one coffee container and / or the cold water container and connected to the water supply device. The water supply device includes a pipe and a rotor pump. One end of the pipe is connected to the cold water container, and the other end of the pipe passes through the rotor pump and is connected to the at least one water outlet. A control device is also included, disposed below the housing and connected to the water supply device. The control device is a weight controller or a time controller. The at least one liquid level sensor is capacitive, probe-type, or ultrasonic. The cabinet is a refrigerator or insulated box, and the internal temperature of the cabinet is below 15°C. The water supply device supplies 1-10 ml of water per minute. Attached Figure Description

[0023] To explain in detail the technical content, structural features, objectives, and effects of the technical solution, the following description is provided in conjunction with specific embodiments and accompanying drawings.

[0024] To make the description of this disclosure detailed and complete, specific embodiments and implementations of this invention are described, but these are not the only forms of implementation or application. Other specific embodiments can be used to achieve the same or equivalent functions.

[0025] Please see Figures 1 to 5 The illustration depicts an ice drip coffee machine, comprising a housing 10 and a water supply device 40. The housing 10 has a door 11 and at least one water outlet 12. The housing 10 has an ice-keeping function to keep the internal temperature below 15°C, preventing excessively high temperatures from affecting the ice drip coffee extraction process. The housing 10 can be, but is not limited to, a refrigerator or a warming box. The water outlet 12 is located on the inner top surface of the housing 10. The interior of the housing 10 has a cold water container 20 and at least one coffee container 30. The opening of the coffee container 30 is connected to the water outlet 12. Correspondingly, the cold water container 20 is located adjacent to the coffee container 30 and is used to hold ice water. In this embodiment, the opening of the coffee container 30 is provided with a filter screen 31 for placing coffee powder. The number of at least one water outlet 12 is the same as the number of at least one coffee container 30, but it is not limited thereto. Multiple water outlets 12 and / or multiple coffee containers 30 can be set according to the adjustment, thereby achieving the function of extracting multiple cups of coffee at one time. In addition, these water outlets 12 can also be evenly arranged in the opening of a coffee container 30 so that the water evenly wets the coffee powder.

[0026] The housing 10 also contains at least one liquid level sensor 60 located adjacent to the coffee container 30 and / or the cold water container 20. The liquid level sensor 60 is electrically connected to the water supply device 40. When the liquid level of the coffee in the coffee container 30 and / or the cold water in the cold water container 20 reaches the user's set value, the water supply from the water supply device 40 will be stopped. The at least one liquid level sensor 60 can be, but is not limited to, capacitive, probe-type, or ultrasonic type. Figure 3 If the at least one liquid level sensor 60 is capacitive, the at least one liquid level sensor 60 is connected to the outer surface of the coffee container 30 and / or the cold water container 20; Figure 4If the at least one liquid level sensor 60 is a probe type, the at least one liquid level sensor 60 is disposed on the inner top surface of the housing 10, extending towards the interior of the coffee container 30 and / or the cold water container 20, so that the probe of the at least one liquid level sensor 60 touches the liquid; Figure 5 If the at least one liquid level sensor 60 is ultrasonic, the at least one liquid level sensor 60 is disposed on the inner top surface of the housing 10 and is disposed corresponding to the opening of the coffee container 30 and / or the cold water container 20.

[0027] The water supply device 40 is located on the outer surface of the housing 10. The water supply device 40 has a rotor pump 41 and a pipe 42. One end of the pipe 42 is connected to the cold water container 20, and the other end of the pipe 42 passes through the rotor pump 41 and is connected to the outlet 12. The rotor pump 41 has a roller shaft inside that compresses the pipe 42 and pushes the water flow so that the cold water flows from the cold water container 20 through the pipe 42 to the outlet 12. Since the rotor pump 41 is less affected by water pressure, the water flow rate can be maintained at 1-10 ml per minute, thereby maintaining the efficiency of iced drip coffee extraction.

[0028] To further explain, the iced drip coffee machine also includes a control device 50 located below the housing 10 and electrically connected to the water supply device 40. When the control device 50 is a weight controller, an electronic scale 51 is located below the coffee container 30 and electrically connected to the control device 50 to detect the weight of the coffee in the coffee container 30. During the coffee extraction process, when the weight reaches the value set by the user, the control device 50 will stop the water supply device 40. In other embodiments, the control device 50 can also be a time controller, which stabilizes the iced drip coffee extraction process by fixing the water supply time of the water supply device 40.

[0029] Accordingly, this new type of iced drip coffee machine provides users with a stable supply of iced drip coffee. Through the housing 10 and the liquid level sensor 60, the temperature and water volume during the extraction process can be stabilized without human operation and supervision. In addition, the rotor pump 41 of the water supply device 40 stabilizes the water flow rate, solving the error effects of traditional manual water supply, bringing a more consistent flavor profile and taste, making the quality of iced drip coffee more stable, and thus improving the consumer's drinking experience.
