Description

Technical Field

[0001] The utility model relates to a tea bar machine. Background Art

[0002] With the improvement of living standards and people's concern about healthy drinking water, tea bar machines, as a device that provides hot water and meets tea drinking needs, have gradually entered homes and offices.

[0003] The working principle of the existing tea bar machine is to introduce water into the internal water pump through the water inlet pipe, the water pump transports the water to the water heating module for heating, and then outputs the hot water to the faucet through the drainage pipe for user use.

[0004] However, during the heating process, a single water heating module is limited by its power and heating efficiency, resulting in limited water output and an inability to quickly provide the required hot water. Frequent heating and shutdown processes also increase the energy consumption of the equipment and shorten its life. Utility Model Content

[0005] The purpose of the utility model is to provide a tea bar machine which improves heating efficiency and shortens the time of producing hot water.

[0006] The purpose of this utility model is achieved in this way:

[0007] A tea bar machine comprises a cabinet and a water heating device, wherein an upper extension plate is provided on the top of the cabinet, and a water receiving area is formed between the top of the cabinet and the upper extension plate;

[0008] The water heating device includes a water inlet pipe, a water pump, at least one water heating module, a circuit board and a drainage pipe. The water pump, circuit board and water heating module are placed in a cabinet. The water inlet pipe is placed in the cabinet. The outlet of the water inlet pipe is connected to the inlet of the water pump. The outlet of the water pump is connected to the water inlet of the water heating module. The water outlet of the water heating module is connected to the inlet of the drainage pipe. The outlet of the drainage pipe extends through the upper extension plate toward the water receiving area for connection to a faucet.

[0009] The water heating module and the water pump are electrically connected to the circuit board respectively, and the circuit board controls the start and stop of the water heating module and the water pump.

[0010] By configuring multiple water heating modules, water heating efficiency can be significantly improved. These modules work together to quickly heat water when users need large quantities of hot water, shortening heating time and improving outlet water temperature stability, meeting users' needs for quick water delivery.

[0011] Thanks to the coordinated design of the water pump and water heating module, a continuous hot water output is achieved. Compared to traditional tea bar machines with a single water heating module, this device provides a more stable hot water flow, avoiding water interruptions caused by frequent heating and shutdown, and improving the user experience.

[0012] The circuit board intelligently controls the water pump and water heating module, and flexibly controls the start and stop of the heating module according to the actual water consumption, thereby avoiding useless heating, reducing energy consumption, and improving the energy efficiency and service life of the equipment.

[0013] The design of the present invention allows the water pump, heating module, and circuit board to be arranged in the cabinet, which is compact and easy to maintain. In addition, the design of the drainage pipe ensures that hot water can flow directly into the water receiving area, which is convenient for use and cleaning, and reduces the inconvenience during operation.

[0014] The purpose of the utility model can also be solved by the following technical measures:

[0015] Furthermore, the water heating module includes a heating tube body and a spiral body, the diameter of the spiral body is smaller than the inner diameter of the heating tube body, the spiral body is fixed in the inner cavity of the heating tube body, and a water channel for guiding the directional flow of water is formed between the inner wall of the heating tube body and the spiral body. One port of the heating tube body is the water inlet, and the other port of the heating tube body is the water outlet. The water inlet and the water outlet are connected to the inner cavity of the heating tube body, and the heating tube body heats the water passing through the water channel.

[0016] Thanks to the introduction of the spiral structure, the heating tube can be placed at any angle without affecting its heating performance. Users are no longer restricted by the placement of the heating tube, which increases the convenience of installation and use.

[0017] The water channel formed by the spiral in the heating tube ensures that even a small flow of water can be quickly guided through, thus avoiding the dry burning problem that is prone to occur in traditional heating tubes when the water supply is insufficient, and improving the safety of use.

[0018] The spiral design allows water to flow along a specific path, increasing water flow speed and heating efficiency. This not only improves the heating effect of the water heater, but also provides hot water more quickly.

[0019] When water flows in the spiral channel, it has more complete contact with the inner wall of the heating tube body, heating more evenly, reducing local overheating or uneven heating, and improving the overall heating performance.

[0020] The design is simple in structure, low in manufacturing cost, and easy to produce and maintain. The combination of the spiral and the heating tube not only improves performance but also maintains structural simplicity, facilitating large-scale promotion and application.

[0021] By optimizing the water flow path and heating efficiency, the design can reduce heat loss, improve energy utilization, help save energy and meet environmental protection requirements.

[0022] Furthermore, the spiral body is a screw, the length of the screw is less than or equal to the length of the heating tube body, and a water channel for guiding water to flow radially along the heating tube body is formed between the threads of the screw and the inner wall of the heating tube body.

[0023] The water channel between the screw thread and the inner wall of the heating tube body guides the water to flow radially, so that the water contacts the inner wall of the heating tube body more fully, improves the heating efficiency and uniformity of the water, and provides a more stable and rapid hot water supply.

[0024] Furthermore, the water outlet of the water heating module is connected to the water inlet of another water heating module, so that multiple water heating modules are connected in series.

[0025] Multiple water heating modules are connected in series, gradually heating the water as it passes through each module, achieving a segmented heating effect. This design allows water to be heated quickly to the desired temperature without significantly increasing the power of each module, significantly improving overall heating efficiency compared to traditional single-module systems.

[0026] By gradually heating the water through multiple heating modules, the water temperature can be stably maintained at the set high temperature standard, thus ensuring a stable output of hot water. Compared with a single module system, the series structure can more reliably maintain a constant water temperature, especially when the water is used continuously.

[0027] The design of multiple water heating modules in series distributes the heating load to different modules, reducing the workload of each module and the risk of overheating. This load sharing method extends the service life of each module and reduces the frequency and cost of system maintenance.

[0028] Because staged heating can quickly reach the set temperature, users can get hot water almost immediately after turning on the faucet, reducing waiting time. This design is particularly suitable for homes and offices with high water consumption, improving the user experience.

[0029] The series heating structure can avoid the high energy consumption problem in single heating. By increasing the water temperature in sections, the overall heating power consumption is reduced. At the same time, the intelligent control system starts and stops each module as needed to achieve energy-saving and environmental protection effects.

[0030] Furthermore, the heating pipe body includes a hollow conduit for water to pass through, an insulating layer and an electromagnetic coil, and the insulating layer is provided on the periphery of the hollow conduit;

[0031] The electromagnetic coil is wound on the insulating layer;

[0032] The electromagnetic coil is energized to generate a changing magnetic field that penetrates the hollow conduit and induces eddy current. The eddy current in the hollow conduit generates heat due to the resistance of the metal to heat the water passing through the hollow conduit.

[0033] When the electromagnetic coil is energized, it generates a changing magnetic field, which penetrates the hollow conduit and induces eddy currents, generating heat inside the conduit. This heating method utilizes the principle of eddy currents to generate heat more quickly and evenly, improving the heating efficiency of the water heater.

[0034] Because the eddy current heating method has high efficiency and low energy loss, it can better utilize electrical energy, and the heating process is more energy-saving and environmentally friendly, which helps to reduce energy consumption and reduce environmental pollution.

[0035] The multi-layer structure of the hollow conduit and insulation layer effectively isolates the electromagnetic coil from the water flow, preventing leakage accidents. The insulation layer provides electrical insulation protection, ensuring safety during use.

[0036] The multi-layer design of the hollow tube, insulation layer and electromagnetic coil enhances the overall structural strength and stability of the heating tube body and reduces material deformation and damage caused by thermal expansion and contraction.

[0037] The magnetic field generated by the electromagnetic coil can quickly induce eddy currents, and the heating response is rapid. Users can get hot water faster, improving the user experience.

[0038] The eddy current heating method reduces the formation of scale and the risk of scaling inside the heating tube, ensuring long-term efficient operation of the equipment and reducing the need for cleaning and maintenance.

[0039] Furthermore, the heating pipe body includes a hollow conduit for water to pass through, an insulating layer and an electric heating film, and the insulating layer is provided on the periphery of the hollow conduit;

[0041] The electric heating film generates heat when electricity is supplied, and the heat heats the hollow conduit through the insulating layer. The heat generated by the hollow conduit heats the water passing through the hollow conduit.

[0042] When the electric heating film is energized, it quickly generates heat, which is effectively transferred to the hollow conduit through the insulation layer, thereby quickly heating the water flowing through the hollow conduit and achieving instant hot water supply.

[0043] The electric heating film is wrapped around the insulation layer, which can evenly distribute heat, so that the water flow in the hollow conduit is evenly heated, avoiding local overheating or uneven heating problems and improving the user experience.

[0044] The design of the hollow conduit and the insulating layer ensures the isolation of the electric heating film from the water flow, effectively preventing the safety hazards caused by the electric heating film directly contacting the water flow, and ensuring electrical safety during use.

[0045] Compared with traditional heating elements, electric heating film has a simple structure and is easy to install, which reduces manufacturing and maintenance costs and improves product reliability and economy.

[0046] The electric heating film has a fast thermal response speed and can provide hot water quickly, which reduces waiting time, improves usage efficiency and meets users' needs for instant hot water.

[0047] The electric heating film has high thermal efficiency and excellent energy conversion efficiency, which reduces heat loss, improves overall energy efficiency, helps save energy and protect the environment, and reduces operating costs.

[0048] The electric heating film is thin and flexible, which makes the overall structure of the heating tube compact and occupies little space, which is conducive to the compactness and miniaturization of the water heater design and is suitable for various installation environments.

[0049] The electric heating film and insulation layer materials are selected from high quality materials with good high temperature resistance and corrosion resistance, which extends the service life of the heating tube body and reduces the need for frequent replacement.

[0050] The surface of the electric heating film is smooth and not easy to adhere to scale, which reduces the risk of scaling inside the hollow tube, maintains the long-term stability of the heating efficiency, and reduces the workload of cleaning and maintenance.

[0051] Furthermore, the heating pipe body includes a hollow conduit for water to pass through, an insulating layer and a heating wire, and the insulating layer is provided on the periphery of the hollow conduit;

[0052] The heating wire is wound on the insulating layer;

[0053] The heating wire generates heat when energized, and the heat heats the hollow conduit through the insulating layer. The heat generated by the hollow conduit heats water passing through the hollow conduit.

[0054] When the heating wire is energized, it quickly generates heat, which is effectively transferred to the hollow conduit through the insulation layer, thereby quickly heating the water flowing through the hollow conduit and achieving instant hot water supply.

[0055] The heating wire is wrapped around the insulation layer, which can evenly distribute heat, so that the water flow in the hollow conduit is evenly heated, avoiding local overheating or uneven heating problems and improving the user experience.

[0056] The design of the hollow conduit and the insulating layer ensures the isolation of the heating wire from the water flow, effectively preventing the safety hazards caused by the heating wire directly contacting the water flow, and ensuring electrical safety during use.

[0057] The heating wire has a fast thermal response speed and can provide hot water quickly, which reduces waiting time, improves usage efficiency, and meets users' needs for instant hot water.

[0058] The heating wire has high thermal efficiency and high energy conversion rate, which reduces heat loss, improves overall energy efficiency, helps save energy and protect the environment, and reduces operating costs.

[0059] Compared with traditional heating elements, electric heating wires have a simple structure and are easy to install, which reduces manufacturing and maintenance costs and improves product reliability and economy.

[0060] The heating wire and insulation layer materials are of high quality and have good high temperature resistance and corrosion resistance, which extends the service life of the heating tube and reduces the need for frequent replacement.

[0061] The surface of the heating wire is smooth and not easy to adhere to scale, which reduces the risk of scaling inside the hollow tube, maintains the long-term stability of the heating efficiency, and reduces the workload of cleaning and maintenance.

[0062] The flexible nature of the heating wire makes the overall structure of the heating tube compact and occupies little space, which is conducive to the compactness and miniaturization of the water heater design and is suitable for various installation environments.

[0063] The material cost of the heating wire and the insulation layer is low, and the manufacturing process is mature, which can reduce production costs and improve the market competitiveness and cost-effectiveness of the product.

[0064] Furthermore, the hollow conduit is a hollow metal tube.

[0065] Furthermore, the cabinet body is divided into an upper storage space for storing the water pump, the water heating module and the circuit board, and a lower storage space for storing bottled water. The inlet of the water inlet pipe extends into the lower storage space for connecting to the bottled water. The cabinet body is provided with cabinet doors corresponding to the upper storage space and the lower storage space, and a microcrystalline panel is provided on the top of the cabinet body.

[0066] The water pump, water heating module, and circuit board are centrally located in the upper storage compartment, while the bottled water is placed in the lower compartment. This creates a compact and well-organized structure, effectively saving space. The partitioned storage design also creates a neater and more aesthetically pleasing appearance, making it suitable for placement in a home or office environment.

[0067] The water inlet extends into the lower storage space and connects to the bottled water supply. A separate door allows for easy replacement of bottled water, making it simple to operate. Simply opening the lower storage space door allows users to easily change water sources without moving the vehicle, greatly enhancing convenience.

[0068] Core components like the water pump, water heating module, and circuit boards are concentrated in the upper storage space, preventing direct contact with the bottled water and effectively protecting the electronic components from the effects of a humid environment. This isolation design reduces equipment failure rates and helps extend equipment life and maintenance cycles.

[0069] The top of the cabinet is equipped with a microcrystalline panel, which is both beautiful and durable. The microcrystalline panel has good heat resistance, stain resistance and easy cleaning, making the overall design of the tea bar machine look high-end and enhancing the user's visual experience and comfort.

[0070] The independent upper and lower storage space design separates the heating part from the water source, reducing the risk of short circuit caused by water leakage. At the same time, the independent cabinet door facilitates inspection and maintenance, ensuring the safety of operation.

[0071] The microcrystalline panel is wear-resistant and stain-resistant, allowing users to simply wipe it clean, maintaining a long-lasting, clean appearance. Separate doors for the upper and lower storage areas facilitate regular inspection and maintenance, simplifying cleaning and maintenance.

[0072] Furthermore, it also includes a water inlet pipe for connecting to the pipeline machine, and the water inlet pipe extends into the cabinet body and is connected to the water inlet pipeline.

[0073] The water inlet pipe is designed to connect to the pipeline water dispenser. Users can choose to connect bottled water or use the pipeline water dispenser directly to meet the needs of different usage scenarios. This design is suitable for different environments such as home, office, and public places, making the use of the device more flexible and diverse.

[0074] By connecting to the pipeline machine, the tea bar machine can achieve uninterrupted water supply, avoiding the need to frequently change the water source due to the limited capacity of bottled water. It is especially suitable for places with high water consumption, further improving the convenience of user experience.

[0075] Pipeline water supply is usually connected to a water purification system, which effectively guarantees the water quality. By connecting the tea bar machine to the pipeline water supply, users can obtain a more stable and high-quality drinking water source, ensuring safe and healthy water use.

[0076] The tea bar machine can flexibly switch between bottled water and pipeline water supply, ensuring a continuous and stable water supply. When the bottled water is exhausted or insufficient, it automatically switches to pipeline water supply, ensuring that users have hot water at all times, enhancing the intelligence and convenience of the device.

[0077] By adding a water inlet pipe interface, the tea bar machine can flexibly connect to the pipeline machine on the basis of supporting bottled water, meeting the diverse water needs of households, small businesses and large public places, and further expanding the applicable scenarios of the equipment.

[0078] Connecting the pipeline machine to supply water reduces the number of times bottled water needs to be replaced, which not only reduces the user's daily maintenance workload, but also reduces the loss inside the equipment that may be caused by frequent changes of water sources, extends the service life of the equipment, and reduces maintenance costs.

[0079] The beneficial effects of the utility model are as follows:

[0080] This utility model uses multiple water heating modules connected in series for segmented heating, and the water temperature increases step by step, ensuring fast and stable output of hot water, significantly improving heating efficiency, and meeting users' needs for quick water collection.

[0081] The utility model has an intelligent control system which starts and stops the water pump and the heating module according to water demand, thereby avoiding useless heating, reducing energy consumption and achieving the effect of energy saving and environmental protection.

[0082] The utility model supports both bottled water and pipeline water supply modes, adapts to different environmental requirements, flexibly switches water supply sources, reduces the frequency of replacing bottled water, and improves convenience of use.

[0083] The utility model has an upper and lower storage space design that isolates the water pump and heating module from the water source, protecting the equipment from moisture damage and making it easier to replace bottled water and maintain internal components.

[0084] The utility model adopts a spiral and multi-stage heating design to heat the water evenly, reduce scale formation, and extend the service life of the equipment. The water heating module designed in this way is no longer limited by the placement of the heating pipe body, which increases the convenience of installation and use.

[0085] The microcrystalline panel of this utility model is not only beautiful, but also has good wear resistance and anti-fouling properties, which improves the safety and service life of the equipment.

[0086] The utility model has multi-stage heating modules connected in series to bring efficient and stable water outlet temperature, reducing waiting time.

[0097] Furthermore, the spiral body 2 is a screw, the length of which is less than or equal to the length of the heating tube body 1 , and a water channel 3 is formed between the screw thread 21 and the inner wall of the heating tube body 1 to guide water to flow radially along the heating tube body 1 .

[0098] Furthermore, the water outlet of the water heating module 30 is connected to the water inlet of another water heating module 30, so that multiple water heating modules 30 are connected in series.

[0104] The working process of users receiving hot water

[0105] When the user turns on the water outlet faucet of the tea bar machine to prepare for hot water, the tea bar machine automatically starts the water pump 20 and the water heating module 30. The specific working process is as follows:

[0106] Water Inlet:

[0107] When the user turns on the water tap, the circuit board 40 detects the water demand and automatically controls the water pump 20 to start.

[0108] The water pump 20 draws water from the bottled water 300 and delivers the water to the first water heating module 30 through the water inlet pipe 100 .

[0109] Sectional heating:

[0110] Water first enters the first water heating module 30. Within this module, the water flows through a hollow conduit 11. When energized, the electromagnetic coil 14 surrounding the conduit generates a changing magnetic field, which in turn induces eddy currents within the hollow metal conduit. The electrical resistance of these eddy currents generates heat within the conduit, heating the water.

[0111] After being heated in the first heating module, the water flows into the second water heating module 30 connected in series. Under the guidance of the spiral 2, the water further contacts the inner wall of the heating tube body 1 along the radial path for secondary heating.

[0112] The water then flows into the third water heating module 30 and continues to be heated to the set temperature. Under the multi-stage series heating, the water temperature gradually increases, ensuring the output of stable high-temperature hot water.

[0113] Hot water output:

[0114] The heated water flows out from the outlet of the third heating module through the drainage pipe 200 and enters the water receiving area 102 through the water outlet faucet for users to take.

[0115] The multi-stage heating module series design ensures constant water temperature and continuous water flow, allowing users to immediately receive constant temperature hot water.

[0116] Automatic control and energy saving:

[0117] The circuit board 40 monitors the status of the water pump 20 and the heating module. When the user turns off the water tap, the circuit board 40 instructs the water pump 20 and each water heating module 30 to stop working and stop the heating process.

[0118] Through automatic start-stop control, the tea bar machine heats up water only when the user actually uses it, avoiding energy waste, ensuring energy saving and environmental protection while extending the service life of the equipment.

[0119] In other embodiments of heating water:

[0120] The water passing through the hollow conduit 11 is heated by the electric heating film:
