Description

Technical Field

[0001] This utility model relates to the technical field of water system, specifically to an integrated device for an instant hot water system applied to a coffee machine. Background Technology

[0002] In modern coffee machines or water dispensers, a complete water system is fundamental to achieving core functions. These devices typically require independent inlet and outlet water lines, and key functional components such as water pumps for water delivery, heaters for instant heating, flow meters for monitoring water flow, and temperature sensors for safety are all indispensable.

[0003] However, in traditional product design and assembly models, these functional components are often installed as independent units in different locations within the equipment casing. This decentralized layout presents significant challenges in actual large-scale production. First, during the assembly process, operators need to perform multiple, dispersed positioning and fixing operations, connecting numerous intricate pipelines, which undoubtedly lengthens the final assembly time and hinders production efficiency. Second, because components are supplied by different vendors, the procurement, quality inspection, and inventory management chains are more complex. Delays in any link directly affect the overall product delivery cycle, increasing the difficulty and uncertainty of supply chain management.

[0004] Therefore, this traditional decentralized structure has become a bottleneck restricting the improvement of production efficiency and market responsiveness. The industry urgently needs a highly integrated solution to simplify installation processes, stabilize product performance, and shorten manufacturing cycles. Utility Model Content

[0005] This invention proposes an integrated instant water system device for coffee machines. The mounting compartment of the outer casing provides integrated installation space for the high-pressure water inlet assembly and the heating water outlet assembly, forming a modular unit that can be detached and installed on the coffee machine as a whole. Compared with traditional decentralized installation, it eliminates the need for multiple decentralized positioning and fixing of components and connection of complex pipelines, significantly reducing the assembly time of the entire machine and improving production efficiency. At the same time, it simplifies procurement, quality inspection, and inventory management, avoids delays in the supply chain of a single component affecting the shipment of the entire machine, and reduces the difficulty of supply chain management. The overall modular design eliminates the need to disassemble components one by one during subsequent equipment maintenance. Only space needs to be reserved on the coffee machine body to install this module, and then the corresponding pipelines can be connected.

[0006] An integrated device for an instant hot water system in a coffee machine, designed for this purpose, includes a housing with a mounting compartment, and further includes: The high-pressure water inlet assembly and the heating water outlet assembly are connected, and both the high-pressure water inlet assembly and the heating water outlet assembly are installed in the mounting compartment of the housing, so that the high-pressure water inlet assembly and the heating water outlet assembly are integrated into the housing to form a module that can be detached and installed as a whole on the corresponding coffee machine body.

[0007] The high-pressure water inlet assembly and the heated water outlet assembly are arranged at left and right intervals along the width or length of the outer shell. The hot water outlet of the heating water outlet assembly can be connected to the first hot water outlet circuit individually or simultaneously to the first hot water outlet circuit and the second hot water outlet circuit by installing different connecting valves.

When the high-pressure pump is started, the liquid enters the heating outlet assembly through the inlet connector, the flow meter, and the high-pressure pump, where it is heated and then output as hot fluid.

[0009] A first tee is provided between the input end of the high-pressure pump and the outlet end of the flow meter. The first end of the first tee is connected to the outlet end of the flow meter, the second end of the first tee is connected to the input end of the high-pressure pump, and the third end of the first tee is provided with a first temperature sensor for detecting the inlet water temperature.

[0010] The connecting pipe between the input end of the high-pressure pump and the second end of the first tee is equipped with a one-way valve to prevent liquid from flowing back into the flow meter. The inlet of the one-way valve is connected to the second end of the first tee, and the outlet of the one-way valve is connected to the input end of the high-pressure pump.

[0011] The housing is equipped with a enclosure for positioning and installing the heating water outlet assembly, and the enclosure separates the heating water outlet assembly from the high-pressure pump. The connecting pipe between the high-pressure pump and the heating water outlet assembly is located between the first temperature sensor and the heating water outlet assembly. The enclosure and the connecting pipe between the high-pressure pump and the heating water outlet assembly form a heat insulation structure to prevent the heat generated by the heating water outlet assembly from affecting the first temperature sensor.

[0012] The high-pressure water inlet assembly also includes a first pressure relief valve, the inlet end of which is connected to the output end of the high-pressure pump, and the outlet end of which is connected to the liquid inlet of the heating water outlet assembly. The first pressure relief valve has a bypass pressure relief branch on its side, and a drain connector connected to the pressure relief end of the bypass pressure relief branch is provided on the outer shell. Under normal operating conditions, liquid flows from the high-pressure pump through the inlet and outlet of the first pressure relief valve to the heated water outlet assembly. When the pressure in the pipeline exceeds the set value, the bypass pressure relief branch of the first pressure relief valve opens, and some liquid is discharged from the bypass pressure relief branch through the drain connector to the outside of the casing.

[0013] The heated water outlet assembly includes a thick film heater and a second temperature sensor for detecting the temperature of the hot water outlet of the thick film heater. The cold water inlet of the thick film heater is connected to the output of the high-pressure pump. The thick film heater has a second three-way or four-way valve on its hot water outlet end. The second three-way and four-way valve are detachably installed on the hot water outlet end of the thick film heater, so that the hot water outlet end of the thick film heater can selectively install the second three-way or four-way valve. The hot water outlet end of the thick film heater is connected to the first hot water outlet circuit separately through the second three-way valve, and the hot water outlet end of the thick film heater is connected to the first hot water outlet circuit and the second hot water outlet circuit simultaneously through the four-way valve.

[0014] When the hot water outlet of the thick film heater is provided with a second three-way valve, the first end of the second three-way valve is connected to the hot water outlet of the thick film heater, the second end of the second three-way valve is used to install a second temperature sensor, and the third end of the second three-way valve is provided with a first water outlet connector, the hot water outlet of the thick film heater, the second three-way valve and the first water outlet connector are connected in sequence to form a first hot water outlet path; When the hot water outlet of the thick film heater is provided with a four-way valve, the first end of the four-way valve is connected to the hot water outlet of the thick film heater, the second end of the four-way valve is used to install the second temperature sensor, the third end of the four-way valve is used to install the second pressure relief valve connected to the second water outlet connector, and the fourth end of the four-way valve is connected to the first water outlet connector; the hot water outlet of the thick film heater and the second pressure relief valve are connected in sequence to form the second hot water outlet path.

[0015] The housing is equipped with a control circuit board, and the electrical components of the high-pressure water inlet assembly and the heating water outlet assembly are electrically connected to the control circuit board. The high-pressure water inlet assembly includes a high-pressure pump for boosting water intake, a first temperature sensor for detecting the water intake temperature, and a flow meter for detecting the water intake flow rate. The heated water outlet assembly includes a thick film heater for heating the liquid and a second temperature sensor for detecting the outlet water temperature. The high-pressure pump, the first temperature sensor, the flow meter, the thick film heater, and the second temperature sensor are electrically connected to the control circuit board, respectively. The thick film heater is also equipped with a temperature controller that is electrically connected to the control circuit board. The outer casing includes a bottom shell with an installation compartment and a top shell fixed to the bottom shell. The high-pressure water inlet assembly and the heated water outlet assembly are encapsulated between the bottom shell and the top shell. The top shell is provided with heat dissipation through holes for auxiliary heat dissipation.

[0016] The beneficial technical effects of this utility model are as follows: The mounting compartment of the outer casing provides integrated installation space for the high-pressure water inlet assembly and the heated water outlet assembly, forming a modular unit that can be easily installed and removed from the coffee machine. Compared to traditional decentralized installation, this eliminates the need for multiple separate positioning and fixing of components and connecting complex piping lines, significantly reducing assembly time and improving production efficiency. It also simplifies procurement, quality inspection, and inventory management, preventing delays in the supply chain of a single component from affecting the overall machine's shipment and reducing supply chain management complexity. The modular design eliminates the need for disassembling components individually during subsequent equipment maintenance; only space needs to be reserved on the coffee machine body to install this module, and then the corresponding piping can be connected.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0023] First embodiment: See Figures 1-5 An integrated device for an instant hot water system used in coffee machines includes a housing 1 with a mounting compartment 101, and further includes: The high-pressure water inlet assembly 2 and the heating water outlet assembly 3 are connected, with the outlet of the high-pressure water inlet assembly 2 connected to the inlet of the heating water outlet assembly 3. Both the high-pressure water inlet assembly 2 and the heating water outlet assembly 3 are installed in the mounting compartment 101 of the outer casing 1, so that the high-pressure water inlet assembly 2 and the heating water outlet assembly 3 are integrated into the outer casing 1 to form a module that can be detached and installed on the corresponding coffee machine body.

[0024] The mounting compartment 101 of the outer casing 1 provides integrated installation space for the high-pressure water inlet assembly 2 and the heating water outlet assembly 3, forming a module that can be completely disassembled and installed on the coffee machine. Compared with traditional decentralized installation, it eliminates the need for multiple decentralized positioning and fixing of components and connection of complex pipelines, significantly reducing the assembly time of the entire machine and improving production efficiency; at the same time, it simplifies procurement, quality inspection and inventory management, avoids the impact of supply chain delays of a single component on the shipment of the entire machine, and reduces the difficulty of supply chain management; the overall modular design eliminates the need to disassemble components one by one during subsequent equipment maintenance. Only the space for installing this module needs to be reserved on the coffee machine body, and then the corresponding pipelines can be connected. The outer casing 1 can be marked with corresponding pipe joint markings (such as markings for water inlet, water outlet, etc.).

[0025] The high-pressure water inlet assembly 2 and the heating water outlet assembly 3 are arranged at left and right intervals along the width or length of the outer shell 1; The hot water outlet of the heating water assembly 3 can be connected to the first hot water outlet circuit individually or simultaneously to the first hot water outlet circuit and the second hot water outlet circuit by installing different connecting valves.

[0026] The high-pressure water inlet assembly 2 and the heating water outlet assembly 3 are arranged alternately along the width or length of the outer casing 1, making the internal layout of the outer casing 1 neat and preventing interference between the two assemblies. This facilitates the layout of internal pipes and wiring, and allows for quick identification of the two assembly components during subsequent maintenance, improving maintenance convenience. The hot water outlet of the heating water outlet assembly 3 can be connected to the first hot water outlet line independently or simultaneously to two water lines through the selective installation of a connecting valve. This allows it to be adapted to different types of coffee machines with single or dual water outlets without modifying the overall structure of the assembly, improving the device's versatility. In addition, this instant hot water system integration device can also be applied to water dispensers.

[0027] The high-pressure water inlet assembly 2 includes a high-pressure pump 201, a water inlet connector 203, and a flow meter 202 for detecting the water inlet flow rate; The inlet end of the flow meter 202 is connected to the inlet connector 203, the outlet end of the flow meter 202 is connected to the input end of the high pressure pump 201, and the output end of the high pressure pump 201 is connected to the liquid inlet of the heating water outlet assembly 3. When the high-pressure pump 201 is started, the liquid enters the heating outlet assembly 3 from the water inlet connector 203 via the flow meter 202 and the high-pressure pump 201, is heated, and then outputs as hot fluid.

[0028] A first tee 204 is provided between the input end of the high-pressure pump 201 and the outlet end of the flow meter 202. The first end of the first tee 204 is connected to the outlet end of the flow meter 202, the second end of the first tee 204 is connected to the input end of the high-pressure pump 201, and the third end of the first tee 204 is provided with a first temperature sensor 205 for detecting the inlet water temperature.

[0029] The first temperature sensor 205 is fixedly installed on the third end of the first tee 204. The temperature probe of the first temperature sensor 205 extends into the first tee 204 to detect the liquid temperature.

[0030] The connecting pipe between the input end of the high-pressure pump 201 and the second end of the first tee 204 is equipped with a one-way valve to prevent liquid from flowing back into the flow meter 202. The inlet of the one-way valve is connected to the second end of the first tee 204, and the outlet of the one-way valve is connected to the input end of the high-pressure pump 201.

[0031] The one-way valve can effectively prevent liquid from flowing back to the flow meter 202, avoid backflow causing distortion of the flow meter 202 detection data, ensure that the control components obtain accurate inlet flow information, and provide a reliable basis for subsequent water flow regulation.

[0032] The housing 1 is provided with a enclosure 102 for positioning and installing the heating water outlet assembly 3, and the enclosure 102 separates the heating water outlet assembly 3 from the high pressure pump 201. The connecting pipe between the high pressure pump 201 and the heating water outlet assembly 3 is located between the first temperature sensor 205 and the heating water outlet assembly 3. The enclosure 102 and the connecting pipe between the high pressure pump 201 and the heating water outlet assembly 3 form a heat insulation structure to prevent the heat generated by the operation of the heating water outlet assembly 3 from affecting the first temperature sensor 205.

[0033] The enclosure 102 can accurately position the heating water outlet assembly 3. The enclosure is mainly used to position and install the thick film heater 301. During installation, there is no need to repeatedly adjust the position, which improves the assembly efficiency of the heating water outlet assembly 3. At the same time, the enclosure 102 isolates the heating water outlet assembly 3 from the high-pressure pump 201 to prevent interference between the two components. The heat insulation structure formed by the enclosure 102 and the connecting pipe can block heat from affecting the first temperature sensor 205, ensuring that the first temperature sensor 205 detects the true inlet water temperature, avoiding temperature detection deviation that leads to heating control errors, and ensuring stable outlet water temperature. The enclosure 102 is integrally formed with the housing or fixed by welding to form a fixed mounting cavity on the housing for mounting the thick film heater 301.

[0034] The high-pressure water inlet assembly 2 also includes a first pressure relief valve 206. The inlet end of the first pressure relief valve 206 is connected to the output end of the high-pressure pump 201, and the outlet end of the first pressure relief valve 206 is connected to the liquid inlet of the heating water outlet assembly 3. The first pressure relief valve 206 has a bypass pressure relief branch 2061 on its side, and the outer shell 1 has a drain connector that is connected to the pressure relief end of the bypass pressure relief branch 2061. Under normal operating conditions, liquid flows from the high-pressure pump 201 to the heating water assembly 3 through the inlet and outlet of the first pressure relief valve 206. When the pressure in the pipeline exceeds the set value, the bypass pressure relief branch 2061 of the first pressure relief valve 206 opens, and some liquid is discharged from the bypass pressure relief branch 2061 through the drain connector to the outside of the housing 1.

[0035] When the first pressure relief valve 206 is working normally, it can stably deliver liquid. When the pressure in the pipeline exceeds the set value, the bypass pressure relief branch 2061 opens to relieve pressure. The bypass pressure relief branch 2061 discharges the liquid through the drain connector of the housing 1 to prevent the pressure relief liquid from stagnating in the housing and damaging other components, and to ensure the normal operation of the components inside the housing. The first pressure relief valve 206 is integrated into the high-pressure water inlet assembly 2, eliminating the need for an additional external pressure relief device, simplifying the device structure, improving integration, and reducing the cost of installing additional pressure relief components. The heated water outlet assembly 3 includes a thick film heater 301 and a second temperature sensor 302 for detecting the temperature of the hot water outlet of the thick film heater 301. The cold water inlet of the thick film heater 301 is connected to the output of the high pressure pump 201. The thick film heater 301 is provided with a second three-way valve 303 or a four-way valve 304 at its hot water outlet. The second three-way valve 303 and the four-way valve 304 are respectively detachably installed on the hot water outlet of the thick film heater 301, so that the second three-way valve 303 or the four-way valve 304 can be selectively installed at the hot water outlet of the thick film heater 301. The hot water outlet of the thick film heater 301 is connected to the first hot water outlet circuit separately through the second three-way valve 303, and the hot water outlet of the thick film heater 301 is simultaneously connected to the first hot water outlet circuit and the second hot water outlet circuit through the four-way valve 304.

[0036] The second temperature sensor 302 can detect the outlet water temperature of the thick film heater 301 in real time and provide timely temperature feedback, facilitating the adjustment of the heating state of the thick film heater 301 and ensuring accurate outlet water temperature. The hot water outlet of the thick film heater 301 can be detachably installed with a second three-way valve 303 or a four-way valve 304. Without replacing the thick film heater 301 itself, it can switch between single and dual water paths through the corresponding solenoid valve, adapting to equipment with different water output requirements and improving the device's adaptability. In addition, the detachable connector design makes it convenient to replace the connector during subsequent maintenance without disassembling the entire heating and water outlet assembly 3, reducing maintenance difficulty. When the hot water outlet of the thick film heater 301 is provided with a second three-way valve 303, the first end of the second three-way valve 303 is connected to the hot water outlet of the thick film heater 301, the second end of the second three-way valve 303 is used to install the second temperature sensor 302, and the third end of the second three-way valve 303 is provided with a first water outlet connector 305, the hot water outlet of the thick film heater 301, the second three-way valve 303 and the first water outlet connector 305 are connected in sequence to form a first hot water outlet path; The mounting compartment 101 of the outer shell 1 is equipped with a control circuit board 4, and the electrical components of the high-pressure water inlet assembly 2 and the heating water outlet assembly 3 are electrically connected to the control circuit board 4 respectively. The high-pressure water inlet assembly 2 includes a high-pressure pump 201 for boosting water inlet, a first temperature sensor 205 for detecting water inlet temperature, and a flow meter 202 for detecting water inlet flow rate. The heated water outlet assembly 3 includes a thick film heater 301 for heating liquid and a second temperature sensor 302 for detecting the outlet water temperature. The high pressure pump 201, the first temperature sensor 205, the flow meter 202, the thick film heater 301 and the second temperature sensor 302 are electrically connected to the control circuit board 4 respectively. The thick film heater 301 is also equipped with a temperature controller 308 that is electrically connected to the control circuit board 4. The outer shell 1 includes a bottom shell 103 with an installation compartment 101 and a front shell 104 fixedly connected to the bottom shell 103. The high-pressure water inlet assembly 2 and the heating water outlet assembly 3 are encapsulated between the bottom shell 103 and the front shell 104. The front shell 104 is provided with heat dissipation through holes 105 for auxiliary heat dissipation.

[0037] Pipe joints are sealed by sealing rings at the connection points. This is common knowledge to those skilled in the art, so it will not be described in detail. The connection method of the corresponding pipe joints will not be described in detail.

[0038] When the second tee 303 is installed, it can stably connect the thick film heater 301, the second temperature sensor 302 and the first water outlet connector 305, ensuring smooth water flow and accurate temperature detection in the first hot water outlet circuit, and meeting the requirements of single water circuit equipment.

[0039] The bottom shell 103 has a mounting cavity for fixing the control circuit board 4. The control circuit board 4 is fixed to the mounting cavity with screws. The mounting cavity surrounds the control circuit board 4 in a ring shape, effectively securing the circuit board 4. When the front shell 104 is fixed to the bottom shell 103, the front shell 104 has an annular rib that abuts against the mounting cavity to prevent liquid from entering the mounting cavity. Alternatively, the bottom shell 103 has a mounting cavity on its outer side for fixing the control circuit board 4. The opening of the mounting cavity has a cover plate to prevent the control circuit board 4 from being installed in the same installation space as the water circuit. When the mounting cavity is located on the outer side, a wiring opening is provided, and a sealing ring with an interference fit to the wire harness is provided inside the wiring opening.

[0040] With the control circuit board 4 fixed inside the bottom shell 103, the coffee machine body is equipped with a cooling fan to dissipate heat from the entire module housing. The cool air from the cooling fan passes through the bottom shell 103 for heat exchange.

[0041] The control circuit board 4 centrally connects the high-pressure pump 201, the first temperature sensor 205, the flow meter 202, the thick film heater 301, the second temperature sensor 302, and the temperature controller 308, enabling coordinated control of each component. For example, when the flow meter 202 detects a flow interruption, the control circuit board 4 can promptly shut down the high-pressure pump 201 and the thick film heater 301 to prevent dry burning and improve the intelligence and safety of the device. The temperature controller 308 can additionally monitor the temperature of the thick film heater 301, providing double protection for the thick film heater 301 and preventing overheating damage. The bottom shell 103 and the front shell 104 encapsulate the components, preventing dust and collision damage to the internal components and improving durability. The heat dissipation holes 105 assist in heat dissipation, preventing high temperatures inside the shell from affecting the performance of components such as the thick film heater 301 and extending the service life of the components. Furthermore, the control part is integrated into the outer shell 1, eliminating the need for an additional external control board and simplifying installation.

[0042] Second embodiment: See Figure 4 and Figure 5 A new instant hot water system integration device for coffee machines differs from the first embodiment in that: a four-way valve 304 is provided on the hot water outlet of the thick film heater 301. The first end of the four-way valve 304 is connected to the hot water outlet of the thick film heater 301, the second end of the four-way valve 304 is used to install a second temperature sensor 302, the third end of the four-way valve 304 is used to install a second pressure relief valve 306 connected to a second water outlet connector 307, and the fourth end of the four-way valve 304 is connected to a first water outlet connector 305. The hot water outlet of the thick film heater 301 is connected, and the second pressure relief valve 306 is connected to the second water outlet connector 307 in sequence to form a second hot water outlet path.

[0043] The third end of the four-way valve 304 is connected to the second pressure relief valve 306 via a tee fitting. The second hot water outlet is mainly used for coffee machines. Since brewing coffee involves a certain pressure and the liquid contains hot air, when the internal pressure of the pipe is high, the pressure is released through the second pressure relief valve 306.

[0044] When the four-way valve 304 is installed, the first hot water outlet and the second hot water outlet can be formed simultaneously. The second pressure relief valve 306 can prevent the pressure of the second hot water outlet from being too high, avoid damage to the components of the second water circuit, and ensure that the pressure is stable and does not interfere with each other when the two water circuits work at the same time. Neither of the two connection methods requires any modification to the core structure of the thick film heater 301. The switching is flexible and reduces the design and manufacturing costs of equipment adaptation.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
