Description

Technical Field

[0001] This utility model relates to the field of beverage vending machine technology, specifically a hot water dispensing module for an automatic beverage vending machine. Background Technology

[0002] With the booming development of the tea beverage market, freshly made tea beverages, as the core growth driver, have become the first choice for young consumers due to their "freshness, customization, and scenario-based" characteristics. Among them, lemon tea, with its refreshing taste and healthy product image, is favored by consumers of all ages, leading to an increasing demand for freshly made tea beverages such as lemon tea. At the same time, consumers are also placing higher demands on the convenience and efficiency of purchasing; they not only pursue the quality of the beverages, but also value the convenience and efficiency of purchasing.

[0003] The current mainstream vending machines still have obvious shortcomings in their functional design. Specifically, the hot water dispensing modules generally lack dynamic monitoring and intelligent early warning mechanisms for water levels, which can easily lead to problems such as water shortage shutdowns and overflow failures during operation, making it difficult to meet the efficient operation requirements of freshly made tea beverage consumption scenarios.

[0004] In view of this, in order to overcome the above-mentioned technical problems, this utility model proposes a hot water dispensing module for an automatic beverage vending machine, which solves the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model proposes a hot water dispensing module for an automatic beverage vending machine. This utility model incorporates a primary water level monitor and a secondary water level monitor to monitor the water level in the heating tank. During water replenishment, if the water level in the heating tank is higher than the capacitive sensor of the secondary water level monitor, the capacitive sensor transmits an electrical signal to the primary delivery pump, causing the primary delivery pump to stop adding water to the heating tank and prevent overflow. When the water level in the heating tank is lower than the capacitive sensor of the primary water level monitor, the capacitive sensor of the primary water level monitor transmits an electrical signal to the primary delivery pump, at which point the primary delivery pump begins replenishing water to the heating tank. This prevents the equipment from shutting down due to water shortage during operation, thus meeting the high-efficiency operation requirements of tea beverage consumption scenarios and improving the practicality of this utility model.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A hot water dispensing module for an automatic beverage vending machine, comprising a housing, wherein the housing is equipped with a water tank, a cup-dispensing module, an ice-making module, an ice-dispensing module, a syrup-dispensing module, a hot water dispensing module, a cup-sealing module, a turntable conveying module, and an ice-weighing module; a water outlet fixedly connected to the housing is provided below the ice-making module; the hot water dispensing module includes a heating chamber; a heater is fixedly installed on the side wall of the heating chamber; an inlet and an outlet are provided at the bottom of the heating chamber; a water pump, a first conveying pump, and a second conveying pump are provided above the heating chamber. A delivery pump is included; the inlet of the pump is connected to a water tank; the outlet of the pump is connected to the inlet of the heating chamber; both the inlet and outlet of the first delivery pump are equipped with T-junction pipes; the inlet of the first delivery pump is connected to the outlets of the water tank and the heating chamber via T-junction pipes; the outlet of the first delivery pump is connected to the water nozzle and the ice-making module via T-junction pipes; the inlet and outlet of the second delivery pump are connected; the outlet of the second delivery pump is connected to the syrup dispensing module; a water level monitoring unit is installed inside the heating chamber; the water level monitoring unit monitors the water level inside the heating chamber.

[0007] Preferably, a guide pipe is installed inside the heating box; the guide pipe is fixed to the bottom of the heating box; the guide pipe is connected to the water inlet.

[0008] Preferably, the water outlet includes a No. 1 water outlet and a No. 2 water outlet; the No. 1 delivery pump is connected to the No. 1 water outlet through a three-way pipe; the inlet end of the No. 2 delivery pump is connected to the No. 2 water outlet.

[0009] Preferably, the water level monitoring unit includes a water level monitor; the upper end of the water level monitor is fixedly connected to the top of the heating box; and a capacitive sensor is installed at the lower end of the water level monitor.

[0010] Preferably, the water level monitor includes a No. 1 water level monitor and a No. 2 water level monitor; the axial length of the No. 1 water level monitor is greater than the axial length of the No. 2 water level monitor.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a No. 1 water level monitor and a No. 2 water level monitor, enables the No. 1 and No. 2 water level monitors to monitor the water level in the heating tank. When water is added, if the water level in the heating tank is higher than the capacitive sensor of the No. 2 water level monitor, the capacitive sensor of the No. 2 water level monitor transmits an electrical signal to the No. 1 delivery pump, causing the No. 1 delivery pump to stop adding water to the heating tank and avoid overflow failure. When the water level in the heating tank is lower than the capacitive sensor of the No. 1 water level monitor, the capacitive sensor of the No. 1 water level monitor transmits an electrical signal to the No. 1 delivery pump, at which time the No. 1 delivery pump starts adding water to the heating tank, preventing the equipment from shutting down due to water shortage during operation. This meets the high-efficiency operation requirements in tea beverage consumption scenarios and improves the practicality of this utility model.

[0013] 2. This utility model installs a guide pipe connected to the water inlet inside the heating box. When the No. 1 delivery pump delivers water into the water inlet, the water entering the water inlet flows into the guide pipe. The water entering the guide pipe flows upward along the guide pipe until it flows out from the upper end of the guide pipe. The cold water flowing out naturally diffuses downward due to gravity, allowing the cold water to fully mix with the upper hot water before slowly flowing through the heating element area. This ensures that the water near the outlet is fully heated by the heater. At the same time, the temperature of the cold water has increased after mixing with the upper hot water, and the temperature difference is reduced when it flows through the heating element. This slows down the crystallization rate of calcium and magnesium ions, reduces the amount of scale formation on the heater surface, and improves the heating efficiency and service life of the heater.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, the hot water dispensing module of an automatic beverage vending machine according to this utility model includes a housing 1. The housing 1 contains a water tank, a cup-dispensing module, an ice-making module, an ice-dispensing module, a syrup-dispensing module, a hot water dispensing module 11, a cup-sealing module, a turntable conveying module, and an ice-weighing module. A water outlet 12, fixedly connected to the housing 1, is located below the ice-making module. The hot water dispensing module 11 includes a heating chamber 13. A heater 131 is fixedly installed on the side wall of the heating chamber 13. An inlet 132 and an outlet 132 are located at the bottom of the heating chamber 13. A water pump 14, a first conveying pump 15, and a second conveying pump 16 are located above the heating chamber 13. The water pump 14... The inlet end is connected to the water tank; the outlet end of the water pump 14 is connected to the inlet 132 of the heating box 13; both the inlet and outlet ends of the first delivery pump 15 are equipped with T-junction pipes 17; the inlet end of the first delivery pump 15 is connected to the outlets of the water tank and the heating box 13 respectively via the T-junction pipes 17; the outlet end of the first delivery pump 15 is connected to the water outlet 12 and the ice-making module via the T-junction pipes 17; the inlet end of the second delivery pump 16 is connected to the outlet; the outlet end of the second delivery pump 16 is connected to the syrup dispensing module; a water level monitoring unit is installed inside the heating box 13; the water level monitoring unit monitors the water level inside the heating box 13.

[0023] In one embodiment of this utility model, a guide pipe 133 is installed inside the heating box 13; the guide pipe 133 is fixedly connected to the bottom of the heating box 13; the guide pipe 133 is connected to the water inlet 132.

[0024] In one embodiment of this utility model, the water outlet includes a first water outlet 134 and a second water outlet 135; the first delivery pump 15 is connected to the first water outlet 134 through a three-way pipe 17; and the inlet end of the second delivery pump 16 is connected to the second water outlet 135.

[0025] In one embodiment of this utility model, the water level monitoring unit includes a water level monitor; the upper end of the water level monitor is fixedly connected to the top of the heating box 13; and a capacitive sensor 18 is installed at the lower end of the water level monitor.

[0026] In one embodiment of the present invention, the water level monitor includes a first water level monitor 136 and a second water level monitor 137; the axial length of the first water level monitor 136 is greater than the axial length of the second water level monitor 137.

[0027] During operation, before a consumer places an order for a beverage through the control panel on cabinet 1, the ice-making module is in operation. At this time, the first delivery pump 15 is controlled to run, and the solenoid valves in the first water outlet 134 and the water outlet 12 of the heating box 13 are controlled to close, while the solenoid valves in the water tank and the preparation module are opened, so that the first delivery pump 15 draws water from the water tank and delivers it to the ice-making module for ice making. After ice making is completed, the water pump 14 is controlled to draw water from the water tank into the heating box 13. When the heating box 13 is full of water, the heater 131 is controlled to run, so that the heater 131 heats the water in the heating box 13.

[0028] After the consumer places an order through the control panel on box 1, the cup dropping module inside box 1 operates and drops the bottom cup to the turntable transmission module. The turntable transmission module then rotates the cup to the ice dispensing station. At this time, the ice making module delivers the pre-prepared ice cubes to the ice dispensing module. The ice cube weighing module weighs the ice cubes delivered to the ice dispensing module. Once the ice cubes reach the preset weight, the ice making module stops delivering ice cubes to the ice dispensing module. The ice dispensing module then adds the set amount of ice cubes into the cup. Next, the turntable transmission module rotates the cup to the syrup dispensing station, allowing the syrup dispensing module to accurately inject the set amount of syrup into the cup. Then, the turntable transmission module rotates the cup to the water dispensing station, where lemon slices fall from the water dispensing station into the cup. Subsequently, the first delivery pump 15 delivers water from the water tank to the water outlet 12, allowing the cold water in the water tank to flow into the cup through the water outlet 12.

[0029] If the customer orders a hot beverage, the solenoid valves in the water tank and ice-making module are closed, while the solenoid valves in outlet 134 and spout 12 are opened. At this time, pump 15 delivers hot water from heating tank 13 to spout 12 through outlet 134, causing hot water to flow from spout 12 and into the cup, thus making a hot beverage for the customer. Afterward, the turntable transfer module rotates the cup to the sealing station. When the cup reaches the sealing station, the sealing module is activated to seal the cup. After the lemon tea beverage is made, the sealed cup can be directly sent to the serving door through the corresponding dispensing device. At the same time, the serving door opens, and the customer takes away the finished lemon tea beverage.

[0030] In winter, due to the low temperature environment, the movement of syrup molecules slows down, the viscosity increases significantly, and crystallization may even occur. For example, sucrose syrup is prone to crystallization when the temperature is below 13°C, which further exacerbates the difficulty of sugar extraction. Therefore, this utility model sets up a second delivery pump 16, which can deliver hot water from the hot water tank to the syrup extraction module. This allows the pipes of the syrup extraction module to be heated by the hot water, which reduces the viscosity of the syrup in the pipes and prevents crystallization. This ensures that the syrup extraction module can stably deliver syrup.

[0031] The core function of the heating box 13 is to heat cold water. Since the density of cold water is greater than that of hot water, if cold water enters directly from the bottom inlet 132 (without the guide pipe 133), the cold water will naturally settle at the bottom of the heating box 13, forming a clear temperature stratification, namely, cold water at the bottom of the heating box 13, warm water in the middle, and hot water at the top. Moreover, the water outlet is located at the bottom of the heating box 13, which can easily cause cold water to flow out from the outlet. In addition, during the replenishment of cold water, when the cold water directly impacts the surface of the high-temperature heating element, the calcium and magnesium ions in the water will crystallize due to the instantaneous high temperature, forming hard scale on the surface of the heating element, which will reduce the heating efficiency of the heater 131 and shorten the service life of the heater 131.

[0032] Therefore, this utility model installs a guide pipe 133 connected to the inlet 132 inside the heating box 13, so that when the first delivery pump 15 delivers water into the inlet 132, the water entering the inlet 132 can flow into the guide pipe 133 connected to it. The water entering the guide pipe 133 flows upward along the guide pipe 133 until the water flows out from the upper end of the guide pipe 133. The cold water flowing out naturally diffuses downward due to gravity, so that the cold water and the upper hot water are fully mixed before slowly flowing through the heating element area. This ensures that the water near the outlet is fully heated by the heater 131. At the same time, the temperature of the cold water has increased after mixing with the upper hot water. When it flows through the heating element, the temperature difference is reduced, the crystallization rate of calcium and magnesium ions is reduced, the amount of scale formation on the surface of the heater 131 is reduced, and the heating efficiency and service life of the heater 131 are improved.

[0033] This invention, by setting up a first water level monitor 136 and a second water level monitor 137, enables these two monitors to monitor the water level in the heating tank 13. When water is added, if the water level in the heating tank 13 is higher than the capacitive sensor 18 of the second water level monitor 137, the capacitive sensor 18 of the second water level monitor 137 transmits an electrical signal to the first delivery pump 15, causing the first delivery pump 15 to stop adding water to the heating tank 13, thus preventing overflow. When the water level in the heating tank 13 is lower than the capacitive sensor 18 of the first water level monitor 136, the capacitive sensor 18 of the first water level monitor 136 transmits an electrical signal to the first delivery pump 15, at which point the first delivery pump 15 begins adding water to the heating tank 13, preventing water shortage shutdowns during equipment operation. This meets the high-efficiency operation requirements of tea beverage consumption scenarios and improves the practicality of this invention.
