Description

Technical Field

[0001] The present invention relates to the field of beverage machines, in particular to a beverage machine with a circulation disinfection structure. Background Art

[0002] Currently, beverage machines can make both cold and hot drinks, are easy to operate, and have a fast processing speed, making them popular among the general public. Existing beverage machines include a cold water tank and a hot water tank, the cold water tank being connected to one set of water outlet pipes, and the hot water tank being connected to another set of water outlet pipes. A hot tank exhaust pipe is installed on the hot tank, which is connected to the top of the water tank, and a cold tank exhaust pipe is installed on the cold tank, which is connected to the top of the water tank. When hot steam is discharged from the hot tank exhaust pipe, it increases the air pressure at the top of the water tank. This can easily cause dirt and bacteria in the hot tank and the cold tank exhaust pipe, as well as dirt and bacteria in the upper part of the water tank, to be poured into the circulating water outlet pipe, the cold tank exhaust pipe, and the overflow pipe, causing the dirt and bacteria to be distributed more widely. Summary of the Invention

[0003] In response to the above-mentioned problems, the present invention proposes a beverage machine with a circulating disinfection structure, which solves the problem that the hot steam discharged from the existing hot bile exhaust pipe will increase the air pressure at the top of the water tank, which will easily cause dirt and bacteria in the hot bile and cold bile exhaust pipes, as well as dirt and bacteria on the upper part of the water tank to be poured into the circulating water outlet pipe, cold bile exhaust pipe and overflow pipe, resulting in a more widespread distribution of dirt and bacteria.

[0004] The technical solution adopted by the present invention is as follows: A beverage machine with a circulation disinfection structure comprises: a machine body, wherein a water tank, a hot bile, a cold bile and a circulating water pump are installed in the machine body, the hot bile is connected to the water tank through a hot bile water inlet pipe, the cold bile is connected to the water tank through a cold bile water inlet pipe, the cold bile is connected to the hot bile through a lower drain pipe, the circulating water pump is connected to the water tank through a circulating water outlet pipe, the hot bile is connected to the circulating water pump through a circulating water pumping pipe, a hot bile exhaust pipe is installed on the hot bile, the hot bile exhaust pipe is connected to the top of the water tank, a cold bile exhaust pipe is installed on the cold bile, the cold bile exhaust pipe is connected to the top of the water tank, a first U-shaped tube is provided in the side wall of the water tank, the hot bile exhaust pipe is connected to the top of the first U-shaped tube, the first U-shaped tube is connected to the second U-shaped tube through a first transverse tube, and the second U-shaped tube is connected to the lower hot exhaust pipe extending downward through the second transverse tube. The present invention utilizes a first U-shaped tube in the side wall of the water tank to cool the hot steam discharged from the hot tank exhaust pipe using the water stored in the water tank itself, thereby preventing a rapid increase in air pressure at the top of the water tank. This effectively prevents dirt and bacteria in the hot and cold tank exhaust pipes, as well as dirt and bacteria in the upper part of the water tank, from entering the circulating water outlet pipe, cold tank exhaust pipe, and overflow pipe, thereby preventing the dirt and bacteria from being more widely distributed. The second U-shaped tube in the present invention also facilitates heat exchange between the hot steam and the cold air in the upper part of the water tank.

[0005] Optionally, the second transverse tube is located at one end of the second U-shaped tube away from the first U-shaped tube.

[0006] Optionally, the cooling tube exhaust pipe is connected to the third U-shaped pipe through a side pipe, and the third U-shaped pipe is connected to the lower cooling exhaust pipe extending downward through a third transverse pipe.

[0007] Optionally, the third transverse pipe is located at an end away from the cooling tube exhaust pipe.

[0008] Optionally, a transverse disinfection tube body is mounted on the first U-shaped tube, and the transverse disinfection tube body includes an outer tube and an inner tube nested in the outer tube, an ultraviolet lamp is mounted in the inner tube, and both the outer tube and the inner tube are made of transparent material. In the present invention, an ultraviolet lamp is provided for disinfecting hot steam and water stored in the water tank, and the refractive index of the outer tube is greater than that of the inner tube. The introduction of hot steam into the transverse disinfection tube body in the present invention avoids the accumulation of condensed water on the outer surface of the transverse disinfection tube body, which affects the disinfection effect. At the same time, the refractive index of the outer tube is greater than that of the inner tube, so that the outer tube and the inner tube nested in the outer tube also play the role of emitting ultraviolet light, making the light of the ultraviolet lamp more dispersed, thereby improving the disinfection effect.

[0009] Optionally, both the outer tube and the inner tube are elliptical.

[0010] Optionally, a heat conduction cavity is formed between the outer tube and the inner tube to facilitate the flow of hot bile steam.

[0011] Optionally, the outer layer of the side tube is provided with a jacket, and the heat conduction cavity is connected to the cavity between the jacket of the side tube and the outer tube via a vertical tube. The horizontal disinfection tube body of the present invention is used to guide hot steam to the cavity between the jacket of the side tube and the outer tube, preheating the cold bile exhaust pipe and preventing the formation of excessive condensation outside the cold bile exhaust pipe. Such condensation will collect dirt and bacteria in the airflow, eventually falling into the water tank, causing secondary contamination.

[0012] Optionally, transverse disinfection tubes are installed on both sides of the first U-shaped tube, forming a diversion cavity between the pair of transverse disinfection tubes, with the bottoms of the lower cold exhaust pipe and the lower hot exhaust pipe facing the diversion cavity. The diversion cavity formed between the pair of transverse disinfection tubes in the present invention not only disperses the water flow downward, but also guides the hot steam to quickly flow to the surface of the liquid in the water tank for rapid cooling.

[0013] Optionally, a first tee pipe is installed on the circulating water outlet pipe, and the middle part of the first tee pipe is connected to the water tank inlet pipe.

[0014] Optionally, a circulation solenoid valve is installed on the lower drain pipe, and a second three-way pipe and a third three-way pipe are also installed on the lower drain pipe. The second three-way pipe is located on the side close to the cold tank, and the third three-way pipe is located on the side close to the hot tank. The second three-way pipe is connected to the hot drain plug, and the third three-way pipe is connected to the cold drain plug.

[0015] Optionally, an overflow pipe is installed on the top of the water tank near the cooling tube exhaust pipe. A first one-way valve is installed on the circulating water outlet pipe, and a second one-way valve is installed on the water tank inlet pipe. The first and second one-way valves are both located at the front end of the first three-way pipe.

[0016] Optionally, the heat bulb is connected to the circulating water pumping pipe through a four-way pipe, and the other pipe openings of the four-way pipe are equipped with a first solenoid valve.

[0017] In summary, the present invention has at least the following beneficial effects: 1. The present invention utilizes a first U-shaped tube in the side wall of the water tank to cool the hot steam discharged from the hot tank exhaust pipe using the water stored in the water tank itself. This prevents a rapid increase in air pressure at the top of the water tank and effectively prevents dirt and bacteria in the hot and cold tank exhaust pipes, as well as dirt and bacteria in the upper part of the water tank, from entering the circulating water outlet pipe, cold tank exhaust pipe, and overflow pipe, thereby preventing the dirt and bacteria from being more widely distributed. The second U-shaped tube in the present invention also facilitates heat exchange between the hot steam and the cold air above the water tank.

[0018] 2. The present invention provides an ultraviolet lamp for disinfecting the hot steam and the water stored in the water tank. The refractive index of the outer tube is greater than that of the inner tube. The passage of hot steam through the transverse disinfection tube body of the present invention prevents condensed water from accumulating on the outer surface of the transverse disinfection tube body and affecting the disinfection effect. At the same time, the refractive index of the outer tube is greater than that of the inner tube, so that the outer tube and the inner tube nested in the outer tube also play a role in radiating ultraviolet light, making the light of the ultraviolet lamp more dispersed and improving the disinfection effect.

[0019] 3. The transverse disinfection tube body in the present invention is used to guide hot steam to the cavity between the jacket and the outer tube of the side tube to preheat the cold bile exhaust pipe and avoid the formation of a large amount of condensed water outside the cold bile exhaust pipe. Such condensed water will gather dirt and bacteria in the air flow and eventually fall into the water tank, causing secondary pollution.

[0020] 4. The guide cavity formed between the pair of transverse disinfection tubes in the present invention plays the role of dispersing water flow downwards on the one hand, and on the other hand, is used to guide hot steam to quickly flow into the liquid surface of the water tank and quickly cool it.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Example 1 The technical solution adopted by the present invention is as follows: like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the present invention discloses a beverage machine with a circulation disinfection structure, comprising: a body 1, in which a water tank 2, a hot bile 3, a cold bile 4 and a circulating water pump 5 are installed. The hot bile is connected to the water tank through a hot bile water inlet pipe 6, the cold bile is connected to the water tank through a cold bile water inlet pipe 7, the cold bile is connected to the hot bile through a lower drain pipe 8, the circulating water pump is connected to the water tank through a circulating water outlet pipe 9, the hot bile is connected to the circulating water pump through a circulating water pumping pipe, a hot bile exhaust pipe 10 is installed on the hot bile, the hot bile exhaust pipe is connected to the top of the water tank, a cold bile exhaust pipe 11 is installed on the cold bile, the cold bile exhaust pipe is connected to the top of the water tank, a first U-shaped tube 12 is provided in the side wall of the water tank, the hot bile exhaust pipe is connected to the top of the first U-shaped tube, the first U-shaped tube is connected to the second U-shaped tube 13 through a first transverse tube 14, and the second U-shaped tube is connected to a lower hot exhaust pipe 16 extending downward through a second transverse tube 15.

[0026] The second transverse tube is located at one end of the second U-shaped tube, away from the first U-shaped tube. The cooling liner exhaust pipe is connected to the third U-shaped tube 37 via a side tube 17. The third U-shaped tube is connected to the downwardly extending lower cooling exhaust pipe 18 via a third transverse tube 41. The third transverse tube is located at one end away from the cooling liner exhaust pipe. A second solenoid valve 38 is installed on the cooling liner.

[0027] The lower drain pipe is equipped with a circulation solenoid valve 19. It also features a second tee 20 and a third tee 21. The second tee is located near the cold end of the tank, while the third tee is located near the hot end. The second tee connects to a hot drain plug 22, while the third tee connects to a cold drain plug 23. An overflow pipe 24 is installed at the top of the water tank, near the cold end exhaust pipe. A first one-way valve 25 is installed on the circulating water outlet pipe, and a second one-way valve 26 is installed on the water tank inlet pipe. Both the first and second one-way valves are located at the front end of the first tee. The hot end is connected to the circulating water pumping pipe via a four-way pipe 27. First solenoid valves 28 are installed at the other ends of the four-way pipe.

[0028] In this embodiment, a water inlet is provided on the top of the water tank, and a cover is provided on the water inlet.

[0029] During high-temperature disinfection mode, the water pump and solenoid valve are activated simultaneously. Water flows from the cold container into the second three-way pipe, passes through the circulation solenoid valve, and then through the first three-way pipe to the hot container for heating. The heated water then flows through the circulation pump, passes through the second one-way valve, and enters the water tank. It then circulates simultaneously into the hot and cold containers until the cold container reaches the set disinfection temperature. Hot steam flows from the hot container exhaust pipe through the first and second U-shaped pipes and sprays downward onto the water surface of the water tank for rapid cooling.

[0030] Example 2 like Figure 5 and Figure 6 As shown, the difference between Example 2 and Example 1 is that the first U-shaped tube is equipped with a transverse disinfection tube body 29, which includes an outer tube 30 and an inner tube 31 nested in the outer tube. The inner tube is equipped with a UV lamp 42. The outer tube and the inner tube are both made of transparent materials. The refractive index of the outer tube is greater than that of the inner tube.

[0031] The outer tube and the inner tube are both elliptical.

[0032] In this embodiment, the horizontal axis of the elliptical structure of the outer tube and the inner tube is wider.

[0033] A heat conduction cavity 32 is formed between the outer tube and the inner tube for hot bile steam to flow in. The outer layer of the side tube is provided with a jacket 33, and the heat conduction cavity is connected to the cavity 34 between the jacket of the side tube and the outer tube through a vertical pipe.

[0034] The circulating water outlet pipe is provided with a first three-way pipe 35 , and the middle portion of the first three-way pipe is connected to a water tank inlet pipe 40 .

[0035] In this embodiment, the outer tube and the inner tube also serve as heat insulation. The UV lamp is covered with a heat-insulating shell. The end of the UV lamp is mounted on the side wall of the water tank.

[0036] When this embodiment is implemented, hot steam is passed into the horizontal disinfection tube body to avoid the accumulation of condensed water on the outer surface of the horizontal disinfection tube body, which affects the disinfection effect. At the same time, the refractive index of the outer tube is greater than that of the inner tube, so that the outer tube and the inner tube nested in the outer tube also emit ultraviolet light, making the light of the ultraviolet lamp more dispersed, thereby improving the disinfection effect.

[0037] Example 3 like Figure 7 As shown, the difference between this embodiment 3 and embodiment 2 is that transverse disinfection tube bodies are installed on both sides of the first U-shaped tube, and a guide cavity 36 is formed between a pair of transverse disinfection tube bodies, and the bottoms of the lower cold exhaust pipe and the lower hot exhaust pipe are opposite to the guide cavity.

[0038] When this embodiment is implemented, the horizontal disinfection tube body is used to guide hot steam to the cavity between the jacket and the outer tube of the side tube to preheat the cold bile exhaust pipe, thereby avoiding the formation of a large amount of condensed water outside the cold bile exhaust pipe. Such condensed water will gather dirt and bacteria in the air flow and eventually fall into the water tank, causing secondary pollution.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformation made by using the contents of the description and drawings of the present invention, directly or indirectly applied to other related technical fields, is also included in the scope of protection of the present invention.
