Description

Technical Field

[0001] This utility model relates to the technical field of beverage machines for brewing beverages, and in particular to a beverage machine that can brew instant iced beverages. Background Technology

[0002] Existing beverage machines capable of making instant powder iced drinks work by passing pre-cooled cold water through an inlet pipe. The cold water and instant powder are mixed in a mixing chamber, then flow out into a stirring chamber to brew a chilled beverage. Instant powders include coffee powder, bean powder, and orange C powder, among others. Ice cubes can also be added to the beverage. In existing beverage machines, the stirring chamber is directly connected to the liquid outlet, and the beverage flows out directly from the outlet after stirring. The disadvantage of this structure is that the resulting chilled beverage is not smooth enough. This is because the powder particles, including sugar particles, dissolve relatively slowly in cold water. The particles do not completely dissolve before flowing out of the outlet. In addition, chilled drinks are usually consumed quickly, resulting in a poor taste. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a beverage machine that can brew instant iced beverages, overcoming the problem that the powder cannot be fully melted when the existing beverage machine makes instant powdered iced beverages, resulting in poor quality.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a beverage machine capable of brewing instant iced beverages, comprising a brewing device, wherein the brewing device has a water-powder mixing chamber and a beverage stirring chamber arranged vertically and connected to each other, the water-powder mixing chamber being connected to a water inlet pipe, the lower part of the beverage stirring chamber being connected to a liquid outlet pipe, the liquid outlet pipe being a vertical pipe, a stirring shaft being provided inside the beverage stirring chamber, the beverage machine having an electronic control device, and a switch valve controlled by the electronic control device being provided on the liquid outlet pipe, the switch valve comprising a valve body integrally formed with the liquid outlet pipe body and a valve core driven to rotate by a switch motor, the switch... The motor is electrically connected to the electronic control device. The upper section of the outlet pipe above the valve core forms an upper drop port on the inner wall of the valve body, and the lower section below the valve core forms a lower drop port on the inner wall of the valve body. The valve core has a through hole that connects the upper drop port and the lower drop port when the valve core is rotated to the open position. The valve core has a sealing element insertion hole perpendicular to the through hole. A silicone seal is inserted into the sealing element insertion hole. The silicone seal has a connecting hole that allows the through hole to pass through. The silicone seal has an upper sealing surface and a lower sealing surface that respectively cover the upper drop port and the lower drop port when the valve core is rotated to the closed position.

[0005] The beverage stirring chamber is formed by a cylinder with a bottom at one end and a cylindrical opening at the other end, the cylindrical opening being sealed. The stirring shaft is coaxially arranged inside the beverage stirring chamber, and a stirring impeller is provided on the stirring shaft. The axis of the stirring shaft is horizontal.

[0006] Specifically, in order to reduce the frictional resistance when the valve core rotates, the interior of both the upper and lower sealing surfaces has a friction-reducing surface that is lower than the sealing surface. This allows the part of the silicone seal that is located on the sealing surface but does not play a sealing role to not rub against the inner wall of the valve body, making the valve core rotate more flexibly.

[0007] Furthermore, the friction-reducing surface is a plane, so that on the cross-section of the valve core, the angle between the sealing surface of the silicone seal and the friction-reducing surface is a large obtuse angle, which is beneficial for the silicone seal to slide in and out of the upper and lower openings.

[0008] Specifically, to prevent the silicone seal from rotating within the seal insertion hole and reduce wear on the sealing surface, both the seal insertion hole and the silicone seal have rectangular cross-sections.

[0009] Specifically, although the silicone seal is an elastic element that can be squeezed into the seal insertion hole, in order to further ensure its reliable positioning, the outer wall of the silicone seal and the inner wall of the seal insertion hole are provided with mutually engaging positioning protrusions and positioning grooves to prevent the silicone seal from falling off.

[0010] Specifically, to further prevent liquid from leaking out of the valve when the switching valve is turned on, the valve core located inside the valve body is a cylindrical switching section, and the part extending out of the valve body is a driving section. The switching section is provided with a circumferential sealing groove, and the sealing groove is filled with a sealing ring.

[0011] Specifically, for ease of installation, the drive section is connected to the output shaft of the switching motor by a slotted coupling.

[0012] Specifically, the stirring impeller is located at the bottom of the beverage stirring chamber.

[0013] Furthermore, the outlet pipe is located outside the bottom of the beverage stirring chamber, which prevents unstirred beverage from flowing out directly.

[0014] Specifically, the water-powder mixing chamber, water inlet pipe, beverage stirring chamber, and liquid outlet pipe are formed by a single component.

[0015] The beneficial effects of this utility model are as follows: This utility model is a beverage machine that can brew instant iced drinks. First, a switch valve controlled by an electronic control device is set on the liquid outlet pipe, which can extend the residence time of the water-powder mixture in the mixing chamber, ensuring that the instant powder and sugar granules are fully dissolved in cold water. Second, an insertable silicone seal is set on the valve core of the switch valve. The two ends of the silicone seal seal block the upper and lower openings. Compared with the common type of valve, the seal will not shift or deform, resulting in better sealing and more flexible rotation of the valve core. Attached Figure Description
