Description

Technical Field

[0001] This application belongs to the field of thawing technology, and particularly relates to an integrated structure of fluid pipelines for a water bath thawing machine and the water bath thawing machine. Background Technology

[0002] A water bath thawing machine is a commonly used device in food processing, laboratories, and medical fields. It primarily uses the heat of water to accelerate the thawing process of frozen foods or samples. This equipment is typically equipped with both water and air circulation systems to ensure uniform water flow throughout the tank, preventing localized temperature differences and maintaining the quality of the thawing product. Furthermore, for food, water bath thawing better preserves moisture and nutrients, preventing water loss during the thawing process; therefore, water bath thawing machines are widely used.

[0003] The existing water bath defrosting machine's water circulation system and air circulation system rely on a large number of pipes and joints for connection to the water tank, thus having the following drawbacks:

[0004] The pipeline has many connection points with joints, making it prone to leaks due to poor sealing.

[0005] The piping is messy, the installation is complicated, and it takes up a lot of space;

[0006] Connecting the water tank to the pipes requires additional tools, resulting in low maintenance and replacement efficiency.

[0007] The gas pipeline is arranged independently from the water pipeline, which makes it easy for it to get tangled with the water pipeline and restricts the installation location, thus affecting the agitation effect of the gas pipeline and reducing the heat exchange efficiency. Utility Model Content

[0008] In view of the above-mentioned problems existing in the prior art, the purpose of this application is to provide a fluid pipeline integrated structure and a water bath defrosting machine having the fluid pipeline integrated structure.

[0009] The technical solution adopted in this application embodiment is a fluid pipeline integrated structure for use in a water bath thawing machine. The water bath thawing machine includes a water tank. The fluid pipeline integrated structure includes a base plate and a first flow channel, a second flow channel, and a third flow channel disposed within the base plate and independent of each other. The first end of the first flow channel is connected to the water tank through a first interface, and the second end of the first flow channel is connected to an external water source for supplying water to the water tank. The first end of the second flow channel is connected to the water tank through a second interface, and the second end of the second flow channel is connected to the outside for discharging water from the water tank. The first end of the third flow channel is connected to the water tank through a third interface, and the second end of the third flow channel is connected to an external air source for supplying air to the water tank.

[0010] In an optional embodiment, the substrate has a first plate facing the water tank, and the first interface, the second interface and the third interface are all disposed on the first plate to facilitate direct connection with the water tank.

[0011] In an optional embodiment, the substrate is provided with a water inlet, a drain outlet, and an air inlet on its periphery. The water inlet is connected to the second end of the first flow channel and is connected to a water supply connector, which is connected to an external water source. The drain outlet is connected to the second end of the second flow channel and is connected to a drain connector. The air inlet is connected to the second end of the third flow channel and is connected to an air supply connector, which is connected to an external air source. By connecting water supply connectors, drain connectors, and air supply connectors to the water inlet, drain outlet, and air inlet respectively, quick and easy connections are possible.

[0012] In an optional embodiment, the substrate is an integral structure, and the first flow channel, the second flow channel, and the third flow channel are all disposed within the same substrate.

[0013] In an optional embodiment, the substrate has a split structure, comprising one independent first sub-substrate and two second sub-substrates. The first and second flow channels are both located within the first sub-substrate, and each of the two second sub-substrates contains a third flow channel. The second ends of the two third flow channels within the two second sub-substrates are connected by an air pipe, which is connected to an external air source. This split structure avoids manufacturing or transportation difficulties caused by excessively large single boards.

[0014] In an optional embodiment, two second sub-subplates are arranged opposite to each other, and each of them has an air pipe interface on its facing side. The two air pipe interfaces are respectively connected to the third flow channel on the second sub-subplate. The air pipe includes a first air pipe and a second air pipe. One end of the first air pipe and one end of the second air pipe are respectively connected to the two air pipe interfaces. The other end of the first air pipe and the other end of the second air pipe are respectively connected to the two air outlet ports of the three-way connector. The air inlet port of the three-way connector is connected to an external air source.

[0015] In an optional embodiment, the first sub-substrate is disposed between the two second sub-substrates and close to the air pipe, and the first sub-substrate avoids the air inlet port of the three-way connector; the side of the first sub-substrate away from the air pipe is provided with a water supply port communicating with the second end of the first flow channel and a drain port communicating with the second end of the second flow channel. The overall layout is reasonable, the arrangement is compact, the space occupation is small, and they do not interfere with each other.

[0016] A water bath defrosting machine includes at least one water tank and an integrated fluid piping structure as described in any of the above embodiments. The integrated fluid piping structure is connected to the water tank, and the water tank is supplied with water, air, and drained through the integrated fluid piping structure. The water bath defrosting machine utilizes an integrated fluid piping structure for water supply, drainage, and air supply, reducing exposed pipes and joints, ensuring smooth air supply, high heat exchange efficiency, and rapid defrosting.

[0017] In an optional embodiment, the water tank is provided with a water inlet, a water outlet, and an air inlet. The water inlet has a water inlet connector that can be plugged into and disconnected from the first interface. The water outlet has a water outlet connector that can be plugged into and disconnected from the second interface. The air inlet has an air inlet connector that can be plugged into and disconnected from the third interface. By using connectors, plugged-in connections are achieved, eliminating the need for additional tools and significantly improving installation and maintenance efficiency.

[0018] In an optional embodiment, multiple hollow protrusions extend downward from the bottom of the water tank to form an inlet connector, an outlet connector, and an air inlet connector, respectively. The upper end of each hollow protrusion communicates with the water tank, and a sealing ring is fitted onto the hollow protrusion. The lower end of each hollow protrusion can be plugged into the corresponding first, second, or third interface in a plug-and-play manner. The outer peripheral wall of the sealing ring tightly fits against the inner peripheral wall of the corresponding first, second, or third interface, achieving a seal between the hollow protrusion and the interface. The connector structure is simple and reasonable, and the sealing ring reduces the risk of leakage.

[0019] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: This application integrates the pipelines for water inlet, drainage and air inlet into the substrate, forming the first flow channel, the second flow channel and the third flow channel respectively, which makes the pipeline neat, with fewer connection points to avoid leakage and the installation position is not restricted. The air path and water path are independent and do not interfere with each other, thus improving the heat exchange efficiency. Moreover, the structure of this application is flexible and can be applied to both single water tank and multi-water tank scenarios. Depending on the number (single / multiple) and volume of water tanks, an integrated structure (single water tank / small volume) or a split structure (multiple water tanks / large volume) can be selected.

[0042] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0043] like Figures 1 to 10As shown in the figure, this application provides a fluid pipeline integrated structure for use in a water bath defrosting machine, which includes a water tank 6. The fluid pipeline integrated structure includes a base plate 1 and a first flow channel 2, a second flow channel 3, and a third flow channel 4 disposed within the base plate 1 and independent of each other. The first end of the first flow channel 2 is connected to the water tank 6 through a first interface 21, and the second end of the first flow channel 2 is connected to an external water source for supplying water to the water tank 6. The first end of the second flow channel 3 is connected to the water tank 6 through a second interface 31, and the second end of the second flow channel 3 is connected to the outside for discharging water from the water tank 6. The first end of the third flow channel 4 is connected to the water tank 6 through a third interface 41, and the second end of the third flow channel 4 is connected to an external air source for supplying air to the water tank 6.

[0044] The fluid pipeline integrated structure of this application integrates a first flow channel 2, a second flow channel 3, and a third flow channel 4 within the substrate 1. The first flow channel 2 forms a water supply channel, the second flow channel 3 forms a drainage channel, and the third flow channel 4 forms a gas supply channel. Water, water, and gas are supplied to the water tank 6 through these three channels, respectively. This ensures that the connection paths between the water tank 6 and the external water source, gas source, and drainage end are completely integrated within the substrate 1, reducing the number of traditional distributed pipelines and joints, and solving the problems of messy pipelines and water leakage.

[0045] In some embodiments, the substrate 1 has a first plate surface 11 facing the water tank 6, and a first interface 21, a second interface 31, and a third interface 41 are all disposed on the first plate surface 11. Distributing the first interface 21, the second interface 31, and the third interface 41 on the first plate surface 11 facing the water tank 6 facilitates direct connection with a connector (described below) on the water tank 6.

[0046] In some embodiments, the substrate 1 is provided with a water inlet, a drain outlet, and an air inlet. The water inlet is connected to the second end of the first flow channel 2, and a water supply connector 22 is connected to the water inlet. The water supply connector 22 is connected to an external water source to deliver external water into the water tank 6 through the water supply connector 22 and the first flow channel 2. The drain outlet is connected to the second end of the second flow channel 3, and a drain connector 32 is connected to the drain outlet to discharge water from the water tank 6 to the outside of the water tank 6 through the second flow channel 3 and the drain connector 32. The air inlet is connected to the second end of the third flow channel 4, and an air supply connector 42 is connected to the air supply outlet. The air supply connector 42 is connected to an external air source to deliver external gas into the water tank 6 through the air supply connector 42 and the third flow channel 4 to agitate the water and the object to be thawed in the water tank 6, thereby improving the thawing effect. By connecting the water supply connector 22, the drain connector 32, and the air supply connector 42 to the water inlet, drain outlet, and air inlet of the substrate 1 respectively, it is convenient to quickly connect to external water and air sources.

[0047] To facilitate the connection of various connectors, the water inlet, drain outlet, and air inlet can all be located on the periphery of the base plate. This provides more operating space and avoids the limitations of operating in confined spaces.

[0048] It is understood that this application does not specifically limit the specific form of the substrate 1, the shape of the three flow channels within the substrate 1, or their relative positions. The only requirement is that the three flow channels integrated into the substrate 1 can achieve water supply, drainage, and air supply to the water tank 6, simplifying the external piping structure and saving space occupied by the external piping. The specific forms of the substrate 1 and the three flow channels are described below using different embodiments.

[0049] Example 1

[0050] like Figure 1 As shown, the substrate 1 is a one-piece structure. This one-piece structure of the substrate 1 is particularly suitable for situations where the water tank 6 of the water bath defrosting machine is a single unit and has a small volume. Since the size of the substrate 1 is generally adapted to or equivalent to the bottom size of the water tank 6, it ensures that gas can enter the water tank 6 evenly and effectively agitate the water. Because the water tank 6 is small and a single unit, the one-piece substrate 1 will not be too large, and there will be no problems of space constraints or waste of material.

[0051] The flow channels within the substrate 1 can be formed in any way, such as by integral injection molding or welding. These methods can reduce splicing steps and improve sealing.

[0052] like Figure 3 and Figure 4 As shown, to facilitate the setting of the flow channel in the substrate 1, the substrate 1 can be divided into two identical plates, namely the upper plate 13 and the lower plate 14. The lower plate surface of the upper plate 13 and the upper plate surface of the lower plate 14 are respectively provided with corresponding flow channel grooves. When the upper plate 13 and the lower plate 14 are snapped together, the flow channel grooves are snapped together to form a complete flow channel.

[0053] To avoid unevenness on the surface of substrate 1 caused by injection molding and welding operations (see...) Figure 3 Since it is prone to accumulating dust and dirt, a sealing plate can be set on the substrate 1 to form... Figure 1 The flat plate shown. The side of the sealing plate facing the water tank 6 forms the first plate surface 11 of the base plate 1. The first interface 21, the second interface 31 and the third interface 41 all extend out of the sealing plate so as to connect with the water tank 6.

[0054] This application does not limit the extension shape and extension length of the three flow channels within the substrate 1. For example... Figure 2 As shown, Figure 2 The image shows one pattern of three flow channels.

[0055] Specifically, such as Figure 2As shown, all three flow channels are located within the same substrate 1. The first flow channel 2 and the second flow channel 3 can both be approximately straight and are arranged side-by-side. The first end of the first flow channel 2 extends to the first surface 11 of the substrate 1, forming a first interface 21. The second end of the first flow channel 2 extends to the periphery of the substrate 1, forming a water inlet. The first flow channel 2 is relatively short so that the first interface 21 is close to the water inlet. The first end of the second flow channel 3 extends to the first surface 11 of the substrate 1, forming a second interface 31. The second end of the second flow channel 3 extends to the periphery of the substrate 1, forming a drain outlet. The second flow channel 3 is relatively short so that the second interface 31 is close to the drain outlet. When the substrate 1 is approximately rectangular, its periphery is formed by a first side 12, a second side, a third side, and a fourth side connected end-to-end. Both the water inlet and the drain outlet are located on the first side 12 of the substrate 1.

[0056] Continue to combine Figure 2 The third flow channel 4 includes a main flow channel 43 and multiple branch flow channels 44 extending from both ends of the main flow channel 43. The ends of the multiple branch flow channels 44 that are not connected to the main flow channel 43 respectively penetrate to the first plate surface 11 of the substrate 1 and form a third interface 41. The main flow channel 43, near its middle portion, can penetrate to the second plate surface of the substrate 1 opposite to the first plate surface 11 or the side surface of the substrate 1 to form an air supply port. In this way, multiple third interfaces 41 are formed, and the gas entering the third flow channel 4 through the air supply ports will be evenly distributed into the water tank 6 through the multiple third interfaces 41.

[0057] Figure 2 There are four branch channels 44 shown in the figure. The four branch channels 44 are connected to both ends of the main channel 43 respectively, forming four third interfaces 41. Figure 2 This is merely an example; in reality, the branch channel 44 can be connected to any position on the main channel 43, and the number of branch channels 44 is not limited to four, but can be five, six, seven, eight, or more. Furthermore, the main channel 43 can not only form an air supply port by extending to the periphery of the substrate 1 near its central position, but also by extending to the periphery of the substrate 1 from one end of the main channel 43.

[0058] Figure 3 The image shows one configuration with three flow channels. For example... Figure 3 As shown, the first flow channel 2 is generally L-shaped and includes a first section and a second section. The first section is generally parallel to the second side of the substrate 1 adjacent to its first side 12, and one end of the first section extends through to the first side 12 of the substrate 1 to form a water inlet and connect to a water supply connector 22. The second section is generally parallel to the third side of the substrate 1 adjacent to its second side, and one end of the second section is connected to the other end of the first section. The other end of the second section extends through to the first plate surface 11 of the substrate 1 to form a first interface 21.

[0059] Figure 3The second flow channel 3 style and Figure 2 The second flow channel 3 is basically the same in shape and is also roughly straight. In order to drain the water in the water tank 6, the first end of the second flow channel 3 extends as far as possible to the middle of the first side so as to facilitate connection with the outlet 62 (described below) near the middle of the water tank 6.

[0060] Continue to combine Figure 3 The third flow channel 4 includes a main flow channel 43 located in the middle of the substrate 1 and multiple branch flow channels 44 connected to both ends of the main flow channel 43. The ends of the multiple branch flow channels 44 not connected to the main flow channel 43 extend to the first surface 11 of the substrate 1 and form third interfaces 41. To form an air supply port on the periphery of the substrate 1, an extension flow channel 45 is also provided within the substrate 1. A portion of the extension flow channel 45 is approximately parallel to the fourth side of the substrate 1 adjacent to its first side 12, and another portion of the extension flow channel 45 is approximately parallel to the second side of the substrate 1 adjacent to its fourth side, so that the extension flow channel 45 forms an approximately L-shape. One end of the extension flow channel 45 is connected to the main flow channel 43 near its middle portion, and the other end of the extension flow channel 45 extends to the first side 12 of the substrate 1 to form an air supply port.

[0061] Example 2

[0062] like Figures 6 to 8 As shown, the substrate 1 has a split structure, meaning it is composed of multiple sub-substrates 1. This split structure is particularly suitable for water bath defrosting machines where there are multiple water tanks 6, or where there is only one water tank 6 but a large volume of each tank. This avoids the problem of using a one-piece substrate 1, which would result in an excessively large and bulky board, inconvenient installation, manufacturing or transportation difficulties, and waste of materials.

[0063] Continue to combine Figures 6 to 8 The substrate 1 includes an independent first sub-substrate 15 and two second sub-substrates 16. A first flow channel 2 and a second flow channel 3 are both located within the first sub-substrate 15. Each of the two second sub-substrates 16 has a third flow channel 4. The second ends of the two third flow channels 4 within the two second sub-substrates 16 are connected via air pipes 5, which are connected to an external air source. This design allows for a reduction in the volume of the substrate 1, avoiding installation inconvenience caused by excessively large substrates limiting installation space.

[0064] like Figure 7As shown, two second sub-sub-base plates 16 are arranged opposite each other, and each has an air pipe interface on its facing side. The two air pipe interfaces are connected to the third flow channel 4 on their respective second sub-sub-base plates 16. The air pipe 5 includes a first air pipe 51 and a second air pipe 52. One end of the first air pipe 51 and one end of the second air pipe 52 are respectively connected to the two air pipe interfaces. The other ends of the first air pipe 51 and the second air pipe 52 are respectively connected to the two air outlet ports of the three-way connector 53. The air inlet port of the three-way connector 53 is connected to an external air source. The three-way connector 53 facilitates quick connection to an external air source.

[0065] Furthermore, the first sub-substrate 15 is disposed between the two second sub-substrates 16 and close to the air pipe 5, and the first sub-substrate 15 avoids the air inlet port of the three-way connector 53. The water supply port and the drain port are located on the side of the first sub-substrate 15 away from the air pipe 5. The overall layout is reasonable, not only compact and space-saving, but also does not interfere with each other, facilitating connection to external water and air sources, as well as external drainage.

[0066] It is understandable that the formation method and shape of the first flow channel 2 and the second flow channel 3 in the first sub-substrate 15, as well as the formation method and shape of the third flow channel 4 in the second sub-substrate 16, are not limited, as long as they can supply water, drain water and supply air to the water tank 6.

[0067] When the water bath defrosting machine includes two or more water tanks 6, each water tank 6 can be equipped with a fluid pipeline integrated structure of Embodiment 2. The water supply connectors 22 of multiple fluid pipeline integrated structures are simultaneously connected to the same external water source, and the drain connectors 32 of multiple fluid pipeline integrated structures are simultaneously connected to the same water receiving container to collect the discharged water uniformly. The air inlet ports of the tee connectors 53 of multiple fluid pipeline integrated structures are simultaneously connected to the same external air source.

[0068] The fluid pipeline integrated structure of this application is applicable to single-tank and multi-tank scenarios. It not only solves the problems of messy pipelines, easy entanglement of air and water lines, and limited installation positions, but also avoids water lines interfering with air lines, affecting the agitation effect of air lines, and reducing heat exchange efficiency.

[0069] This application also provides a water bath defrosting machine, which includes a water tank 6 and a fluid pipeline integrated structure as described in any of the above embodiments. The fluid pipeline integrated structure is connected to the water tank 6, and the water tank 6 is supplied with water, air, and drained through the fluid pipeline integrated structure. The water bath defrosting machine uses a fluid pipeline integrated structure for water supply, drainage, and air supply, reducing the number of scattered exposed pipes and joints, solving the problems of water leakage and mess. Moreover, the third flow channel 4 is not affected by the first flow channel 2 and the second flow channel 3, resulting in smooth air supply, better agitation of the liquid in the water tank 6, improved heat exchange efficiency, and accelerated defrosting.

[0070] Figure 9 A top view of a water bath defrosting machine including a water tank of 6. Figure 10 A top view of a water bath defrosting machine comprising two water tanks 6 arranged side by side. (See attached image.) Figure 9 and Figure 10 As shown, the bottom of water tank 6 is provided with a water inlet 61, a water outlet 62, and an air inlet 63 that communicate with the inside of water tank 6. Figure 4 and Figure 8 As shown, the inlet 61 is equipped with an inlet connector 64, which can be plugged into the first interface 21; the outlet 62 is equipped with an outlet connector 65, which can be plugged into the second interface 31; and the air inlet 63 is equipped with an air inlet connector 66, which can be plugged into the third interface 41. By using connectors, plugged-in connections are achieved, eliminating the need for additional tools and significantly improving installation and maintenance efficiency. Furthermore, the third interface 41 of the third flow channel 4 is connected to the air inlet connector 66 at the bottom of the water tank 6, allowing gas to be ejected from below, driving the liquid to be thawed and the liquid in the water tank 6 to move up and down in convection, accelerating heat exchange and improving thawing efficiency.

[0071] like Figure 5 As shown, multiple hollow protrusions 67 extend downwards from the bottom of the water tank 6 to form a water inlet connector 64, a water outlet connector 65, and an air inlet connector 66, respectively. The upper end of the hollow protrusion 67 is connected to the water tank 6, and a sealing ring 68 is fitted over the hollow protrusion 67. The lower end of the hollow protrusion 67 can be plugged into the corresponding first interface 21, second interface 31, or third interface 41 in a plug-and-play manner. The outer peripheral wall of the sealing ring 68 is tightly fitted to the inner peripheral wall of the corresponding interface, achieving a seal between the hollow protrusion 67 and the interface. That is, the hollow protrusion 67 forms a male head, and the interface forms a female head. The male and female heads are integrally formed with the water tank 6 and the base plate 1, respectively, without additional independent connectors, reducing costs and assembly parts, and further improving sealing performance. Moreover, the male and female heads are sealed by the sealing ring 68 (or interference fit), eliminating the need for additional independent connectors and further reducing the risk of leakage.

[0072] like Figure 4 and Figure 8 As shown, a one-way valve 69 is provided inside the hollow protrusion 67 that forms the air inlet connector 66 to prevent water in the water tank 6 from flowing back into the third flow channel 4 and damaging the fan that supplies air to the third flow channel 4.

[0073] The water bath defrosting machine of this application embodiment has a base plate 1 that can be either an integrated or split structure depending on the number (single / multiple) and size of the water tanks 6. This balances the high efficiency of integration in small-volume scenarios with the installation flexibility in large-volume / multiple-water-tank scenarios, avoiding manufacturing or transportation difficulties caused by an excessively large single base plate 1. When split, it can be connected to the corresponding water tank 6 through branch flow channels 44 or extended sub-base plates 1, providing flexible structural adaptation to meet different needs.

[0074] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
