Description

Technical Field

[0001] This utility model relates to the field of beverage machine technology, specifically a beverage machine capable of producing hot coffee and cold-extracted coffee. Background Technology

[0002] Currently, beverages such as coffee and fruit juice have become popular daily drinks for many people due to their healthy and low-calorie properties. Among them, cold-brewed coffee, compared to hot-brewed coffee, has less acidity and causes less caffeine loss, resulting in a rich and unique taste that is gradually gaining popularity. However, most coffee machines on the market are currently designed for hot extraction, lacking machines capable of performing both hot and cold extraction simultaneously.

[0003] CN201922489977.5 discloses a coffee machine capable of making hot and cold brew coffee, including a water tank, a funnel, a coffee cup, a heating element, and a water pump. The water tank outlet is connected to one end of the water pump via a pipe, and the other end of the water pump is connected to the water inlet of the heating element. The water outlet of the heating element is connected to the shower head on the funnel via a water inlet pipe, and the water outlet below the funnel corresponds to the coffee cup. This technical solution uses the same piping to provide hot water for hot brewing and drinking water for cold brewing. If cold brewing is performed immediately after hot brewing, the residual heat in the piping will heat the cold water to lukewarm, affecting the effect and taste of the cold brew. Conversely, if the piping is allowed to cool completely after hot brewing, the waiting time will be too long, affecting usability. Utility Model Content

[0004] The purpose of this invention is to provide a beverage machine that can produce both hot and cold brew coffee, thereby solving the problem that when current coffee machines that can produce both hot and cold brew coffee switch from hot to cold brew operation, the water temperature is affected by the temperature of the first pipe circuit, resulting in poor flavor of the cold brew coffee, thus overcoming the shortcomings of the prior art.

[0005] This utility model provides a beverage machine capable of producing hot and cold-extracted coffee through the following technical solution, comprising a heater, a first tube, and a second tube. The heater provides heat to the first tube, which is then heated. The first and second tubes are connected in parallel, with their ends respectively connected to the water tank and the extraction device of the beverage machine. Hot water for hot extraction is provided through a water channel inside the first tube, and drinking water for cold extraction is provided through the second tube. An inner channel is provided through the first tube, and the second tube is inserted into the inner channel.

[0006] Furthermore, the heater is a cylindrical thick-film heater wrapped around the outer wall.

[0007] Furthermore, the first pipe fitting also includes a spiral water channel formed on the outer wall of the first pipe fitting, an inlet pipe and an outlet pipe provided on both ends of the first layer of the first pipe fitting, and a water channel through hole provided connecting the inlet pipe and the spiral water channel, and connecting the outlet pipe and the spiral water channel.

[0008] Furthermore, the thick film heater is a polyimide heating film or a polyester heating film.

[0009] Furthermore, the thick film heater is also equipped with a temperature controller.

[0010] Furthermore, the outer wall of the second pipe fitting is covered with a heat insulation layer.

[0011] This invention has the following advantages: It uses a spiral water channel with a continuous hollow structure as the first pipe, and inserts a second pipe into the inner hole of the first pipe. The outer wall of the second pipe is covered with a heat insulation layer, so that the second pipe and the first pipe can be set up independently. That is, the water of the second pipe is used for cold extraction, and the water of the first pipe is used for hot extraction. This allows for instant switching between hot and cold extraction without water temperature cross-contamination, ensuring the effect and taste of cold-extracted coffee liquid and improving the usage effect.

[0023] The following reference Figures 1-4 This application describes a beverage machine capable of producing hot coffee and cold-brewed coffee according to some embodiments.

[0024] A beverage machine capable of producing hot and cold brew coffee includes a thick-film heater 1, a first pipe 2, and a second pipe 3. The first pipe 2 includes an inner channel penetrating the entire first pipe, a spiral water channel 5 formed on the outer wall of the first pipe, and an inlet pipe 7 and an outlet pipe 8 disposed on both ends of the first pipe. At both ends of the first pipe, water channel through holes 4 are provided connecting the inlet pipe 7 and the spiral water channel 5. Similarly, water channel through holes 4 are also provided connecting the outlet pipe 8 and the spiral water channel 5. The second pipe 3 is inserted into the inner channel of the first pipe. The thick-film heater 1 surrounds the outer wall of the first pipe. The inlet pipe 7 of the first pipe 2 and the inlet side of the second pipe 3 are both connected to the water tank of the beverage machine. The outlet pipe 8 of the first pipe 2 and the outlet side of the second pipe 3 are both connected to the extraction device of the beverage machine.

[0025] The second pipe 2 is inserted through the inner channel of the first pipe 2, and the outer wall of the second pipe 3 can also be covered with a heat insulation layer 6.

[0026] The first fitting 2 and the second fitting 3 are connected in parallel. Taking a coffee machine as an example, the water inlets of the first fitting 2 and the second fitting 3 are connected to the water tank of the coffee machine. For example, the water tank is connected to the inlet of the first fitting 2 and the inlet of the second fitting 3 via a three-way solenoid valve. The outlets of the two fittings are connected to the extraction device of the coffee machine. The second fitting 3 provides room temperature water from the water tank. The water in the spiral channel 5 of the first fitting 2 is heated into hot water by a thick film heater, providing hot water for hot extraction. The separate second fitting avoids the passive heating of cold water caused by residual heat when sharing the first fitting's circuit. The insulation layer 6 also prevents the second fitting from being radiated by heat from the water inside the first fitting, ensuring that the water temperature during cold extraction is room temperature. The first fitting 2 and the second fitting 3 can provide hot water for extraction and room temperature water respectively in a coffee machine, and can provide hot water for drinking and room temperature water respectively in a water dispenser.

[0027] The thick-film heater 1 is a cylindrical, flexible thick-film heater wrapped around the outer wall of the spiral water channel 5. The flexible thick-film heater is made of polyimide or polyester heating film. Using a thick-film heater allows for better adhesion to the spiral water channel 5, fully heating the water within it. Simultaneously, the spiral water channel increases the water flow distance and the contact area with the pipe wall, resulting in more uniform and effective water heating. The use of the flexible thick-film heater and the heating method of 5 also significantly reduces the space occupied by the water heating device in beverage machines such as coffee machines.

[0028] In this implementation, the spiral waterway adopts an external thread structure.

[0029] A temperature controller 9 is also provided on the thick film heater 1, which can realize the regulation of the thick film heater 1.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
