[0036] Please refer to Figures 1 to 10, the pipeline docking module 300 provided by the present utility model is mainly applied in a steam system. The steam system generally further includes a steam boiler 100, which generally has a cold water inlet and a steam outlet, and generally has heating devices installed therein. When cold water is connected to the cold water inlet from the outside, the heating devices start to operate and heat the cold water connected into the steam boiler 100. When the temperature and pressure in the steam boiler 100 reach the preset values, steam is generated. The steam finally discharges outwards through the steam outlet.

[0037] To ensure the safe operation of the steam boiler 100, the steam system generally further includes a safety valve body 200, which can be arranged at any opening provided on the steam boiler 100. When the pressure in the steam boiler 100 continuously rises and exceeds the safety threshold, the safety valve body 200 can automatically or manually relieve the pressure of the steam boiler 100 to ensure the working safety of the steam boiler 100.

[0038] The steam system can be applied in beverage processing equipment according to actual needs. The beverage processing equipment generally further includes a housing, and the steam system is at least partially installed inside the housing. The steam system and the housing can be directly connected or indirectly connected through other components, and the connection method between the two can be a non-detachable connection or a detachable connection.

[0039] The specific type of the beverage processing equipment is not limited, and it can be a product that finally obtains beverages such as coffee and soy milk after performing any processing operations on raw materials such as coffee beans and soybeans. Among them, the processing operations include but are not limited to operations such as grinding, brewing, and weighing. Based on this, in addition to the housing and the steam system, the beverage processing equipment further includes at least one functional module. The functional module can be but is not limited to a grinding module, a brewing module, a milk supply module, etc. At least one of the functional modules needs to use steam during its working process, thus forming a steam inlet. Or a beverage outlet is provided on the outer front side of the housing, and the beverage outlet can be connected in communication with the brewing module for the prepared beverage to discharge outwards. At this time, the steam outlet of the steam system can also be connected in communication with a separate beverage outlet or share a beverage outlet connected in communication with the brewing module to be able to discharge high-temperature steam outwards separately.

[0040] Multiple channel structures are pre-integrated inside the pipeline docking module 300, and each channel structure can be applied to at least connect at least one opening of the steam boiler 100 to improve the function of the steam boiler 100.

[0041] Since the present utility model mainly improves the pipeline docking module 300, the structure of the pipeline docking module 300 will be mainly described below with reference to the drawings.

[0042] Please combine with Figures 2 to 10, the pipeline docking module 300 provided by the present utility model includes a docking main body 310 and a switching valve 320. Among them, the docking main body 310 is provided with a liquid inlet channel 311 and a waste discharge channel 312. The liquid inlet channel 311 includes a liquid inlet section 311a and at least two liquid outlet sections. The liquid inlet section 311a is used to connect to external cold water. Each liquid outlet section includes a first liquid outlet section 311b penetrating the outer wall of the docking main body 310 and a second liquid outlet section 311c. The second liquid outlet section 311c is connected to communicate the liquid inlet section 311a and the waste discharge channel 312; at least one switching valve 320 is provided, and the switching valve 320 acts at the connection between the liquid inlet section 311a and each liquid outlet section and / or acts at the connection between the second liquid outlet section 311c and the waste discharge channel 312 to adjust the water flow rate at the position where it is located.

[0043] In the technical solution provided by the present utility model, the docking main body 310 is pre-integrated with a liquid inlet channel 311 and a waste discharge channel 312, and the liquid inlet channel 311 is further subdivided into a liquid inlet section 311a and multiple liquid outlet sections, which can replace the staggered arrangement of multiple pipe structures, achieving streamlining in terms of structure and installation; since the orientations of the liquid inlet channel 311 and the waste discharge channel 312 on the docking main body 310 are relatively fixed, it is ensured that during use, at least there will be no mutual pulling between the two, resulting in poor connection or structural damage, which helps to improve the service life of each channel structure; in addition, the liquid inlet section 311a can connect external cold water to each liquid outlet section. Under the separate control of each switching valve 320, each liquid outlet section can achieve intelligent water output. The first liquid outlet section 311b can be docked with other functional modules downstream according to actual needs; the second liquid outlet section 311c can guide the cold water to the waste discharge channel 312. On the one hand, it can increase the fluidity of the dirt in the waste discharge channel 312 through the water flow. Especially when the waste discharge channel 312 is connected to external solid dirt, it helps to prevent blockage; on the other hand, it can dissipate heat in the waste discharge channel 312 with the help of cold water. Especially when the waste discharge channel 312 is connected to external hot water or steam, it helps to further ensure the service life of the docking main body 310 and improve the user's use safety.

[0044] It can be understood that when the pipeline docking module 300 is applied to a steam system, the pipeline docking module 300 can be installed at any orientation of the steam boiler 100, as long as it can maximize the convenience of docking the pipeline docking module 300 with the steam boiler 100. For example, in Figure 1 In the shown structure, the pipeline docking module 300 is installed below the steam boiler 100. The top of the steam boiler 100 is provided with a steam outlet and a cold water inlet, and the bottom of the steam boiler 100 is provided with a drain outlet. Of course, in other embodiments, the steam outlet, cold water inlet and drain outlet of the steam boiler 100 can also have other opening schemes, which are not limited.

[0045] The pipeline docking module 300 is arranged below the steam boiler 100 and is detachably or non-detachably connected to the casing. The pipeline docking module 300 includes a docking main body 310. The docking main body 310 is generally arranged in a block shape, and sufficient space is reserved inside it for the liquid inlet channel 311 and the waste discharge channel 312 to be opened. Moreover, the pipeline docking module 300 arranged in a block shape is also easier to be positioned and installed in the casing, improving the installation stability between the pipeline docking module 300 and the casing.

[0046] In addition, please refer to Figures 2 to 3 As shown, the pipeline docking module 300 may further include at least one docking part. According to actual needs, the docking part can be inserted at any channel structure on the docking main body 310 and at least partially protrudes from the outer wall of the docking main body 310 so as to be able to directly or indirectly connect a channel structure with an opening structure of other components such as the steam boiler 100. A through-hole structure communicating with the corresponding channel structure is provided through the docking part, which can be used as an extension channel of the channel structure. Of course, the docking part can be a structure integrally formed with the docking main body 310, or a structure detachably or non-detachably connected after being separately formed from the docking main body 310.

[0047] Please specifically combine Figures 4 to 10 As shown, the docking main body 310 is provided with a liquid inlet channel 311. The liquid inlet channel 311 includes at least one liquid inlet section 311a and at least two liquid outlet sections:

[0048] Among them, the liquid inlet section 311a penetrates through the outer wall of the docking main body 310 to form a liquid inlet, and the liquid inlet can be communicatively connected to a water storage tank built in the beverage processing device or a water source such as a faucet outside the beverage processing device.

[0049] At least one of the liquid outlet sections penetrates through the outer wall of the docking main body 310 to form a liquid outlet. This liquid outlet section is the first liquid outlet section 311b, and this liquid outlet can be communicatively connected to any module in the beverage processing device that requires hot water, such as the cold water inlet of the steam boiler 100; or it can also be communicatively connected to the flushing port / water inlet in the milk supply system; or communicatively connected to the flushing port / water inlet in the brewing module.

[0050] The first liquid outlet section 311b has one or at least two. When there are at least two first liquid outlet sections 311b, the orientations of the liquid outlet openings formed by each liquid outlet section on the outer wall of the docking body 310 can be set to be the same or at least two different. The liquid outlet openings formed by each liquid outlet section on the outer wall of the docking body 310 can be centrally arranged on a certain side outer wall of the docking body 310 or dispersedly arranged on different side outer walls of the docking body 310. When the orientations or opening positions of at least two liquid outlet openings are different, liquid outlet openings in different orientations can be provided for other water-requiring components docked with the pipeline docking module 300, so that the connection scheme between the pipeline docking module 300 and other water-requiring components is more matched and material consumption is reduced.

[0051] For example Figures 2 to 10 In the shown scheme, there are two first liquid outlet sections 311b. The liquid outlet opening of one of the first liquid outlet sections 311b is arranged upward and is used for communicating and connecting with the flushing port of the milk supply module; the liquid outlet opening of the other second liquid outlet section 311c is arranged laterally and is used for communicating and connecting with the cold water inlet of the steam boiler 100.

[0052] At least one of the liquid outlet sections is formed inside the docking body 310 and is connected to the waste discharge channel 312 to form the second liquid outlet section 311c, so as to achieve the purpose of guiding the cold water introduced by the liquid inlet section 311a to the waste discharge channel 312.

[0053] The waste discharge channel 312 is arranged through the docking body 310 and forms a waste discharge inlet 312b and a waste discharge outlet 312d on the outer wall of the docking body 310 respectively. The waste discharge inlet 312b can be connected to any module in the beverage processing equipment that needs to discharge sewage, such as the sewage discharge port of the steam boiler 100, the sewage discharge port of the brewing module, the sewage discharge port of the milk supply module, etc.; the sewage discharge outlet can be connected to the built-in sewage collection bin in the beverage processing equipment or to the sewage collection bin outside the beverage processing equipment to discharge the dirt outward.

[0054] It can be understood that any functional module in the beverage processing device, including the steam boiler 100, may generate dirt such as waste steam, waste liquid, or waste residue during its operation. At least part of the dirt can enter the waste discharge channel 312 through the waste discharge inlet 312b and is finally discharged outwards through the sewage discharge outlet. At this time, with the setting of the second liquid discharge section 311c, when the dirt connected to the waste discharge inlet 312b contains solid residues, cold water is introduced into the waste discharge channel 312 through the second liquid discharge section 311c, and the fluidity of the cold water can be used to quickly discharge the dirt. Or when the dirt connected to the waste discharge inlet 312b has a high temperature, cold water is introduced into the waste discharge channel 312 through the second liquid discharge section 311c, and the cold water can be used to reduce the temperature in the waste discharge channel 312, avoiding damage to the structure of the pipeline connection module 300 due to excessive temperature, or preventing the dirt discharged outwards through the sewage discharge outlet from having too high a temperature and affecting the user experience. Or when the dirt connected to the waste discharge inlet 312b is prone to deterioration or generates peculiar smells, cold water is introduced into the waste discharge channel 312 through the second liquid discharge section 311c. The clean cold water is used to dilute and neutralize the dirt in the waste discharge channel 312, and after the waste discharge in the waste discharge channel 312 is completed, the waste discharge channel 312 is cleaned with cold water, which helps to improve the overall usage quality of the machine.

[0055] In a further solution, the connection between the second liquid discharge section 311c and the waste discharge channel 312 is arranged close to the waste discharge inlet 312b. That is, the cold water introduced into the waste discharge channel 312 through the second liquid discharge section 311c is closer to the waste discharge inlet 312b, so that the cold water can generate one or several of the above functions closer to the waste discharge inlet 312b. Especially when cooling or cleaning the inside of the waste discharge channel 312, it can be ensured that the action can be exerted on the entire waste discharge channel 312 as much as possible.

[0056] It should be noted that in order to prevent the dirt in the waste discharge channel 312 from flowing back into the second liquid discharge section 311c and further polluting the liquid inlet section 311a or other liquid discharge sections, in a further solution, a one-way valve body can also be arranged at any part of, for example, the second liquid discharge section 311c, ensuring that only cold water can be introduced into the waste discharge channel 312 through the second liquid discharge section 311c, and no liquid can flow back into the second liquid discharge section 311c through the waste discharge channel 312.

[0057] And / or, in order to better process the dirt in the waste discharge channel 312, in a further solution, devices for assisting in processing the dirt in the waste discharge channel 312, such as disinfection devices for disinfection and sterilization, deodorization devices for removing peculiar smells, etc., can also be arranged at the second liquid discharge section 311c close to the waste discharge channel 312 (or downstream of the one-way valve body).

[0058] In addition, on the premise of ensuring sufficient water flow rate, structural improvements or the addition of a pressure booster device can also be made at the connection between the second liquid outlet section 311c and the waste discharge channel 312 to increase the flow rate or water pressure of the cold water entering the waste discharge channel 312 via the second liquid outlet section 311c. By using the cold water with high flow rate or high water pressure, the above-mentioned effects of cooling and cleaning in the waste discharge channel 312 can be enhanced.

[0059] Based on any of the above embodiments, in combination with Figures 7 to 10 , the docking body 310 is further formed with an emptying channel 313, and the emptying channel 313 is used to connect the drain outlet of the steam boiler 100 and the waste discharge channel 312. When the steam boiler 100 is in a non-operating state, especially when the steam boiler 100 needs to be transferred or maintained, the emptying channel 313 is used to discharge the liquid inside the steam boiler 100 to the waste discharge channel 312 to ensure that the inside of the steam boiler 100 is in a relatively dry state.

[0060] In a further solution, the connection between the emptying channel 313 and the waste discharge channel 312 is arranged close to the waste discharge outlet 312d. In this way, on the one hand, the layout directions of the emptying channel 313, the waste discharge channel 312, and the third liquid outlet section can be reasonable, and on the other hand, the emptying channel 313 can be closer to the waste discharge outlet 312d, which is beneficial to discharging the water inside the steam boiler 100 more quickly and unobstructed.

[0061] Furthermore, in an embodiment, the connection between the emptying channel 313 and the waste discharge channel 312 divides the waste discharge channel 312 into a first channel section 312a communicating with the waste discharge inlet 312b and a second channel section 312c communicating with the waste discharge outlet 312d. The flow area of the first channel section 312a is S1, and the flow area of the second channel section 312c is S2, where S1 is less than S2. That is, the flow area of the channel section through which at least the liquid introduced into the waste discharge channel 312 via the emptying channel 313 flows is larger, which helps to improve the emptying efficiency of the steam boiler 100. And on the other hand, the first channel section 312a can also reserve enough space for connecting with the emptying channel 313.

[0062] In addition, based on any of the above embodiments, in a further solution, the docking body 310 is arranged in a block shape and is made of a heat-conducting material. Specifically, for example, the docking body 310 can be made of a metal material. The metal material has sufficient structural strength and can assist in cooling the hot water or hot steam flowing in the waste discharge channel 312.

[0063] Of course, according to actual needs, the docking body 310 can also be made of a transparent material at least at the parts where each channel structure is formed, so that the liquid flow conditions in each channel structure can be visualized.

[0064] It should be noted that in each of the above embodiments, each channel structure may be composed of one or several straight channel segments, or may be composed of one or several curved channel segments, or may be composed of at least one straight channel segment and at least one curved channel segment connected in sequence.

[0065] The switching valve 320 can be arranged at any position of the channel structure according to actual needs. For example Figures 1 to 10 In the illustrated embodiment, three switching valves 320 can be provided. The first of the three switching valves 320 is arranged at the connection between the liquid inlet section 311a and the first liquid outlet section 311b, the second is arranged at the connection between the liquid inlet section 311a and the second liquid outlet section 311c, and the third is arranged at the drain channel 313.

[0066] The switching valve 320 can be any valve body structure that can adjust the opening degree of the channel structure at its location. For example, it can be an electromagnetic valve, a pressure valve, etc., without limitation.

[0067] In addition, according to actual needs, one or several of the first liquid outlet sections 311b can be provided with a diameter change at the channel segment near its liquid outlet, for example, reducing the aperture to reduce the flow rate or appropriately increasing the flow velocity.

[0068] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
