The hot water boiler heats the incoming cold water to obtain hot water, and the hot water is finally discharged outward through the hot water discharge pipe to functional modules such as the brewing module. With the increasing diversification of the functions of beverage cooking equipment, there may be more than one functional module that requires hot water, and the demand for hot water in each functional module that requires hot water is different.

[0044] Please refer to Figures 1 to 9 , the present invention provides a hot water boiler 200. The hot water boiler 200 is mainly applied in a hot water system, and the hot water system can be specifically applied in a beverage processing device.

[0045] It can be understood that the hot water boiler 200 includes a boiler main body 210 and components such as heating devices and sensor devices provided in the boiler main body 210. The beverage processing device includes a housing and various functional modules. The hot water system is at least partially accommodated in the housing. The beverage processing device can be used to process raw materials such as coffee beans and soybeans to finally obtain beverages such as coffee liquid and soy milk. Among them, the processing process can be but is not limited to grinding, brewing and extraction, etc. Therefore, the above-mentioned functional modules can be but are not limited to grinding modules, brewing modules, milk supply modules, etc.

[0046] Specifically, in actual applications:

[0047] The hot water system has a water inlet mode. In this mode, the boiler body 210 can be connected to an external cold water source. The cold water source can be a water source outside the beverage processing device, such as a fixed faucet in the environment where the beverage processing device is placed; the cold water source can also be a water source built into the beverage processing device, such as a cold water tank with a certain capacity.

[0048] The hot water system also has a heating mode. In this mode, the heating device in the boiler body 210 starts to operate and heats the cold water, and finally obtains hot water at the required temperature. The heating device can be selected according to actual needs, such as a resistance heating device, an infrared heating device or an electromagnetic heating device, etc.

[0049] The hot water system also has a water outlet mode. In this mode, the boiler body 210 can be connected to an external functional module to be able to provide hot water to the functional module. Among them, the functional modules that require hot water are, for example, but not limited to, a brewing module, a milk supply module, etc. Of course, the hot water system can also directly provide hot water to, for example, a beverage outlet outside the casing.

[0050] In view of the above, since the main improvement point of the present utility model lies in the hot water boiler 200, the hot water boiler 200 will be mainly described below with reference to the drawings.

[0051] Please refer to Figures 2 to 9 , the hot water boiler 200 provided by the present utility model includes a boiler body 210, a main pipe group 220 and a first branch pipe group 230. Among them, the boiler body 210 is provided with at least two hot water outlets; the main pipe group 220 is provided as one, and the main pipe group 220 includes a main pipeline 221 connected to a hot water outlet, and a main control valve 222 provided on the main pipeline 221; the first branch pipe group 230 can be selectively provided with one or at least two, and each first branch pipe group 230 includes a first branch pipeline 231 and a first branch control valve 232 provided on the first branch pipeline 231, and each first branch pipeline 231 is connected to the same hot water outlet.

[0052] In the technical solution provided by the present utility model, the boiler main body 210 independently outputs hot water via each hot water outlet. The main pipeline 221 in the main pipeline group 220 is separately connected to a hot water outlet, and can be used to provide hot water with relatively large flow rate and stable flow velocity for, for example, a brewing module provided in the beverage processing equipment; the structures and installation methods of each first branch pipeline group 230 are basically the same, and one or at least two of them can be selectively assembled according to the different hot water requirements of the beverage processing equipment, so that the number of assembled first branch pipeline groups 230 is adapted to the number of other functional modules requiring hot water; since the hot water requirements and demand frequencies of other functional modules requiring hot water except the brewing module are relatively low, by setting each first branch pipeline group 230 to receive hot water from the same hot water outlet, and each first branch control valve 232 can control the on-off of the corresponding first branch pipeline 231, it is possible to make the structure of the whole machine simpler and the hot water discharge function more efficient while relatively independently meeting the hot water requirements of each other functional module without opening too many hot water outlets in the hot water boiler 200.

[0053] It can be understood that the boiler main body 210 is provided with at least two hot water outlets communicating with its inner cavity. The diameters of the two hot water outlets can be set to be the same or different. The main pipeline group 220 is set to one, and generally the main pipeline 221 in the main pipeline group 220 is also set to one. The main control valve 222 can be various valve bodies capable of controlling the opening degree of the main pipeline 221, such as an electromagnetic valve. The first branch pipeline group 230 is set to one or at least two, and the first branch pipeline 231 in each first branch pipeline group 230 can be set to one, so that the corresponding first branch control valve 232 can independently adjust the opening degree of this first branch. Similarly, the type of the first branch control valve 232 is not limited and can be an electromagnetic valve or the like.

[0054] It should be noted that the present design does not limit the target functional modules output by the main pipe group 220 and the first branch pipe group 230. However, it can be understood that since the main pipe 221 in the main pipe group 220 is independently connected to a hot water outlet (for the sake of easy understanding, the following defines this hot water outlet as the first hot water outlet 211), optionally, the main pipe 221 of the main pipe group 220 can be connected to the functional module with relatively high usage frequency and relatively large water demand in the beverage cooking equipment, such as the brewing module. When the first branch pipe group 230 is set to at least two, each first branch pipe 231 shares the same hot water outlet (for the sake of easy understanding, the following defines this hot water outlet as the second hot water outlet 212). At this time, under the control of the corresponding first branch control valve 232, it can be set that only one of each first branch pipe 231 can be conducted each time, and the remaining first branch pipes 231 are in a closed state. Or it can be set that any number of first branch pipes 231 can be conducted simultaneously each time. The first branch pipe group 230 can be connected to the functional module with relatively low usage frequency or relatively small water demand in the beverage cooking equipment, such as the milk supply module, or directly connected to the beverage outlet outside the machine shell.

[0055] When the first branch pipe group 230 is set to multiple, the structures and other characteristics of each first branch pipe group 230 are generally set to be the same to improve the versatility of each first branch pipe group 230. Of course, according to actual needs, at least some of the structural characteristics in each first branch pipe group 230 can also be set to have relatively obvious or relatively unobvious differences.

[0056] When the first branch pipe group 230 is set to multiple, during the design or use of the whole machine, the specific quantity can be set based on actual needs. At this time, for the sake of increasing convenience, it can be set that each first branch pipe group 230 is centrally installed in the set area in the hot water boiler 200, and the disassembly and assembly methods of each first branch pipe group 230 are kept as the same as possible. Specifically, it can be set that each first branch pipe group 230 is installed outside the boiler main body 210, directly installed on the outer wall of the boiler main body 210, or installed and fixed through an installation structure such as an installation plate.

[0057] Multiple installation positions can be pre-formed in the set area. The arrangement method of each installation position is not limited, and it can be set to be linearly arranged, array arranged, radially arranged, etc. along a certain direction according to actual needs. Each installation position can be defined by a visible structure, such as defined by a visible shape, color, etc., or can be defined by, for example, their respective disassembly and assembly structures. The first branch pipe group 230 can be selectively installed at any installation position to better dock with the target functional module.

[0058] Specifically, in one embodiment, each first branch pipe group 230 is provided with an installation structure, and a plurality of docking structures can be arranged at intervals in a set area. An installation structure is detachably connected to a docking structure. At this time, the positions of the respective docking structures constitute installation positions. It is equivalent to that the installation positions have quantity limitations and orientation limitations.

[0059] Or in one embodiment, at least one of the first branch pipe groups 230 (for the convenience of understanding, hereinafter defined as the adjustable first branch pipe group 230) is movably arranged relative to the boiler main body 210, so that the orientation of the adjustable first branch pipe group 230 can be adjusted. At this time, an installation position is defined at any position on the moving stroke of the adjustable first branch pipe group 230. It is equivalent to that the installation positions have no quantity limitations and orientation limitations.

[0060] Among them, the movement of the adjustable first branch pipe group 230 can be a one-way or multi-way translational movement, so that the position of the adjustable first branch pipe group 230 can be adjusted, so that the adjustable first branch pipe group 230 can be installed at the most suitable position between the boiler main body 210 and the target functional module according to the actual installation environment. Or, the movement of the adjustable first branch pipe group 230 can be a one-way or multi-way rotational movement, so that the orientation of the docking port of the first branch pipe 231 in the adjustable first branch pipe group 230 can be adjusted, so that the adjustable first branch pipe group 230 can be installed at the most suitable orientation between the boiler main body 210 and the target functional module according to the actual installation environment.

[0061] There are various solutions to achieve the above object. For example, a guide rail mechanism is provided between the set area and the adjustable first branch pipe group 230, and / or the first branch pipe 231 of the adjustable first branch pipe group 230 is composed of a structure that can be telescopically deformed or bent. And so on, without limitation.

[0062] In view of the above, in specific applications, the first branch pipes 231 are sequentially connected end to end in the direction of approaching and departing from the second hot water outlet 212 to form a long tubular shape. That is, the first branch pipes 231 are linearly arranged, which helps to simplify the structure. The first branch pipes 231 can be arranged adjacent to the outer wall of the boiler main body 210 and are adapted to the shape of the boiler main body 210 at the location. For example, when the boiler main body 210 is cylindrical, the first branch pipes 231 can be arranged linearly along the radial or axial direction of the boiler main body 210, or can be arranged in an arc shape along the circumferential direction of the boiler main body 210.

[0063] Then in one embodiment, two adjacent first branch pipes 231 are integrally formed. Specifically, for example Figure 3As shown, the hot water boiler 200 includes a first pipe body. The port of the first pipe body forms a water inlet, which is communicated with the second hot water outlet 212. A plurality of water outlets are arranged at intervals along the axial direction of the side wall of the first pipe body. The pipe segments between each water outlet and the water inlet constitute the first branch pipeline 231.

[0064] Or in an embodiment, two adjacent branch pipelines are detachably connected. Specifically, as Figures 4 to 6 shown, the hot water boiler 200 includes a plurality of second pipe bodies. Each second pipe body has a water inlet, a connection port, and a water outlet. The water inlet of the second pipe body located downstream in the water flow direction is communicated with the connection port of the upstream second pipe body. Each second pipe body defines each first branch pipeline 231.

[0065] Of course, it should be noted that the above-mentioned first pipe body and second pipe body do not constitute limitations on their material, shape, size and other structural features. According to actual needs, the above-mentioned first pipe body and second pipe body can be set to have any suitable structural features.

[0066] When each first branch pipeline 231 is detachably connected, every two adjacent first branch pipelines 231 are detachably connected through a plug-in part, which helps to quickly disassemble and assemble the required number of first branch pipelines 231.

[0067] In view of any of the above embodiments, in a further solution, the hot water boiler 200 further includes a second branch group 240. The second branch group 240 can be selectively provided with one or at least two. Each second branch group 240 includes a second branch pipeline 241 and a second branch control valve 242 provided on the second branch pipeline 241. Each second branch pipeline 241 is connected to the same cold water source. The structures of each first branch group 230 and each second branch group 240 are the same. The structural design of the second branch group 240 can refer to the above-mentioned first branch group 230 and will not be elaborated. By making the structures of each first branch group 230 and each second branch group 240 the same, on the one hand, it helps the fitting disassembly between the first branch group 230 and the second branch group 240, and on the other hand, it also makes the overall appearance structure of the hot water system unified, and makes the processing and forming process of the first branch group 230 and the second branch group 240 simpler and more economical.

[0068] Each first branch pipeline 231 and each second branch pipeline 241 can be centrally installed in the same set area or installed dispersedly. Taking the case of centralized installation in the same set area as an example, similarly to the above, the arrangement modes of each first branch pipeline 231 and each second branch pipeline 241 are not limited. For example, each first branch pipeline 231 and each second branch pipeline 241 are sequentially connected end to end in the direction close to and away from the hot water outlet to form a long tubular shape; wherein, each second branch pipeline 241 is located on the side of each first branch pipeline 231 away from the hot water outlet, and the adjacent first branch pipeline 231 and second branch pipeline 241 are arranged in a partitioned manner through a partition structure. In this way, on the premise of ensuring the relatively centralized installation of each first branch pipeline 231 and each second branch pipeline 241, each first branch pipeline 231 and each second branch pipeline 241 can be made as independent as possible and not interfere with each other.

[0069] As described above, when adjacent every two first branch pipelines 231 are detachably connected through a plug-in component, similarly, adjacent every two second branch pipelines 241 are detachably connected through a plug-in component. Specifically, in an embodiment, adjacent every two first branch pipelines 231 and adjacent every two second branch pipelines 241 are both detachably connected through a first plug-in component 250, and the first plug-in component 250 is provided with a through hole 251; the adjacent first branch pipeline 231 and second branch pipeline 241 are detachably connected through a second plug-in component 260, and the second plug-in component 260 is hermetically arranged, that is, a hole structure communicating the first branch pipeline 231 and the second branch pipeline 241 is not formed, thus constituting a partition structure.

[0070] The outer shape structures of the first plug-in component 250 and the second plug-in component 260 can be set to be substantially the same. Taking the above-mentioned second pipe body as an example, the first plug-in component 250 can be a rubber part inserted between the connection port of the adjacent upstream second pipe body and the water inlet of the downstream second pipe body. This rubber part can not only realize the detachable connection between the two second pipe bodies through its own elastic deformation, but also seal the connection part between the two second pipe bodies. Of course, in order to play the roles of connection and sealing simultaneously, the first plug-in component 250 and the second plug-in component 260 can also be composed of a rigid part and a sealing ring sleeved on the outside.

[0071] In view of any of the above embodiments, further, the main control valve 222 conducts the main pipeline 221 when powered on, and conversely closes the main pipeline 221 when powered off. Similarly, the first branch control valve 232 conducts the corresponding first branch pipeline 231 when powered on, and conversely closes the corresponding first branch pipeline 231 when powered off; the second branch control valve 242 conducts the corresponding second branch pipeline 241 when powered on, and conversely closes the corresponding second branch pipeline 241 when powered off. In this way, it can be ensured that when the main control valve 222, the first branch control valve 232, and the second branch control valve 242 are normally powered off or powered off due to a fault, they all maintain a state of not outputting hot water or outputting cold water outward, which helps to reduce losses and reduce the degree of defectiveness.

[0072] In addition, in one embodiment, the main pipe group 220 further includes a waste discharge connection pipeline 223, and the waste discharge connection pipeline 223 is connected to the side wall of the main pipeline 221 in a communicating manner to divide the main pipeline 221 into a liquid inlet main pipe section 221a and a liquid outlet main pipe section 221b; the main control valve 222 is arranged at the communicating place between the main pipeline 221 and the waste discharge connection pipeline 223, and conducts the liquid inlet main pipe section 221a and the liquid outlet main pipe section 221b when powered on; and conducts the liquid inlet main pipe section 221a and the waste discharge connection pipeline 223 when powered off. In this way, when powered off, according to actual needs, the liquid inlet main pipe section 221a and the waste discharge connection pipeline 223 can be conducted, so that the water accumulated in the boiler main body 210 and the liquid inlet main pipe section 221a can be discharged outward along the waste discharge connection pipeline 223; or the liquid outlet main pipe section 221b and the waste discharge connection pipeline 223 can be conducted, so that the water accumulated in the target function module (such as the brewing module) connected to the main pipe group 220 and the liquid outlet main pipe section 221b can be discharged outward along the waste discharge connection pipeline 223.

[0073] It should be noted that when the hot water boiler 200 as described above is applied to a hot water system, in one embodiment, the hot water system further includes a pipeline connection module. The pipeline connection module further includes a block 110.

[0074] When the boiler main body 210 is provided with a cold water inlet 213, a liquid inlet channel 111 can be preset in the block 110. The liquid inlet channel 111 is provided with a cold water access port 111a for communicating with an external cold water source in a connected manner; the liquid inlet channel 111 is further provided with a cold water outlet port 111b, and the cold water outlet port 111b is connected to the cold water inlet 213 of the boiler main body 210 in a communicating manner to connect the external cold water source into the boiler main body 210 and operate the above water inlet mode. In addition, when the second branch pipe group 240 is provided as described above, the cold water outlet port 111b of the liquid inlet channel 111 can be set to at least two, one of which is connected to the cold water inlet 213 of the boiler main body 210 in a communicating manner, and the other is connected to each second branch pipeline 241 in a communicating manner, which helps to connect the external cold water source to each second branch pipeline 241.

[0075] According to different preset operation modes of the hot water system, the block 110 can also be preset with different channels. Compared with the staggered splicing setting of excessive pipe structures, by presetting channels in the block 110, on the one hand, it helps to simplify the overall structure of the hot water system and makes the disassembly and assembly with the hot water boiler 200 more convenient; on the other hand, it makes the relative positions of the respective channels fixed, with basically no relative displacement, and the structural strength of each channel is sufficient, without any problems such as deformation due to tensile force, which helps to improve the connection strength between the channels and the openings, and ultimately helps to improve the overall service life and reliability of the hot water system.

[0076] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
