[0032] See also Figures 1 to 3204 , the first and second connectors 206 are connected to each other via a first connector 203 and a second connector 206 are connected to each other via a second connector 206.

[0033] Specifically, the water tank 201 can be applied to, but not limited to, the hydraulic module 200. The hydraulic module 200 can be applied to a heating unit. In one embodiment, the heating unit may include a heat source device and a heating terminal. The hydraulic module 200 is a core component of the heating unit. It organically combines the heat source device and the heating terminal to achieve heat generation, transmission and distribution. The hot water generated by the heat source device can be input into the water tank 201 in the hydraulic module 200 for storage. The hot water in the water tank 201 can be transported to each heating terminal, thereby providing heat for the entire heating unit. Among them, the heat source device may include but not limited to an outdoor unit, a gas boiler, a solar water heater, etc. The heating terminal may include but not limited to a domestic water tank, an area one system, and an area two system.

[0034] The external unit can include a heat pump system, which heats cold water into hot water and then transfers the hot water to the water tank 201 of the hydraulic module 200 for distribution. A gas furnace can use the heat generated by gas combustion to heat cold water to produce hot water. The hot water output by the gas furnace is then transferred to the water tank 201 of the hydraulic module 200 for distribution. A solar water heater can be connected to the hydraulic module via a pipeline. The solar water heater uses solar energy to directly heat cold water to produce hot water, which is then transferred to the water tank 201 of the hydraulic module 200 for distribution.

[0035] In one example, the heating terminal can be a domestic water tank. The water tank 201 in the hydraulic module 200 can deliver hot water to the coil within the domestic water tank. The hot water transfers heat through the coil to the domestic water in the domestic water tank, raising the temperature of the domestic water. The domestic water tank can be connected to a water outlet valve such as a faucet or showerhead, and the heated domestic water can be supplied to the user through the water outlet valve such as the faucet or showerhead.

[0036] In one example, the heating terminal can be a zone 1 system. The water tank 201 in the hydraulic module 200 can deliver hot water to the zone 1 system. The zone 1 system can include a heater suspended from the indoor ceiling, including but not limited to a fan coil unit (FCU). The fan coil unit can dissipate the heat from the hot water into the room, raising the indoor temperature.

[0037] In one example, the heating terminal can be a zone 2 system. The water tank 201 in the hydraulic module 200 can deliver hot water to the zone 2 system, which can include floor heating and / or radiators. The floor heating dissipates the heat from the hot water to the floor, while the radiators dissipate the heat from the hot water into the room, thereby raising the floor and room temperatures.

[0038] Optionally, the water tank 201 can be a buffer water tank, a device within the hydraulic module 200 that stabilizes the pressure within the hydraulic module 200, stores heat and maintains temperature, and optimizes the operation of the hydraulic module 200. The water tank 201 can store a certain amount of water and act as a buffer during the operation of the hydraulic module 200, making the operation of the entire hydraulic module 200 more stable and efficient.

[0039] The workpiece 219 may be any component of the hydraulic module 200 that needs to be installed and connected to the water tank 201. The workpiece 219 may include, but is not limited to, a drain valve 225, a cold water delivery pipe, a hot water delivery pipe, and the like.

[0040] In the prior art, water tanks are equipped with joints, and threaded connections are commonly used. This, to a certain extent, limits the efficiency of hydraulic system installation and maintenance. Since threaded connections require specialized tools for installation and removal, the operation process is complex and prone to leaks. This connection method not only prolongs installation time and increases labor costs, but also inconveniences maintenance personnel when equipment failures require repair, reducing work efficiency.

[0041] In the embodiment of the present invention, the clamp 202 is detachably provided with the first clamping slot 205 and the second clamping slot 207. When the water tank 201 and the workpiece 219 are disassembled, the clamp 202 can be removed, thereby releasing the connection lock between the water tank 201 and the workpiece 219, so that the water tank 201 and the workpiece 219 can be separated. During installation, the male head 227 can be inserted into the insertion space 204 of the female head 226 and the first clamping slot 205 and the second clamping slot 207 can be aligned and connected. Then the clamp 202 can be inserted into the first clamping slot 205 and the second clamping slot 207 to fix the first connection part 203 and the second connection part 206 in connection, thereby fixing the joint 217 and the workpiece 219 in connection. In summary, the operating space can be reduced to a certain extent, and the difficulty of after-sales replacement of parts can be reduced. Basically, no tools are required in the whole process. The clamp 202 includes but is not limited to a clamping pin ( Figure 4 ),card( Figure 5 )wait.

[0042] It is understandable that in Figure 4 In the illustrated embodiment, the card member 202 is in the form of a card pin, and the connecting arm 215 can function as an operating portion, making it convenient for the user to operate the card member 202 for assembly and disassembly.

[0043] exist Figure 5 In the illustrated embodiment, the card member 202 is in the form of a card and further includes a handle 229 . The handle 229 is connected to the side of the connecting arm 215 away from the clamping portion 216 . The handle 229 can facilitate the user to operate the card member 202 for assembly and disassembly.

[0044] In the above-mentioned water tank 201, the first card slot 205 and the second card slot 207 are detachably penetrated by the clamp 202 so that the joint 217 and the workpiece 219 are fixedly connected through the first connecting part 203 and the second connecting part 206, so that the joint 217 and the workpiece 219 can be disassembled and assembled by disassembling the clamp 202, which simplifies the disassembly and assembly process to a certain extent and improves the installation and maintenance efficiency.

[0045] In some embodiments, please combine Figure 2 and Figure 3 The first connecting portion 203 is a female connector 226 , and the water tank 201 includes a clamping member 202 , which passes through a first clamping slot 205 .

[0046] Specifically, the first connection part 203 is a female head 226, and correspondingly, the second connection part 206 is a male head 227. The second connection part 206 can be inserted into the insertion space 204 of the first connection part 203. The first connection part 203 is provided with a first card slot 205, and the second connection part 206 is provided with a second card slot 207. The card 202 can pass through the first card slot 205 and fit into the second card slot 207, so that the first connection part 203 and the second connection part 206 are fixedly connected.

[0047] In the above embodiment, the first card slot 205 and the second card slot 207 are detachably provided through the clamp 202 so that the joint 217 and the workpiece 219 are fixedly connected through the first connecting portion 203 and the second connecting portion 206, so that the joint 217 and the workpiece 219 can be disassembled and assembled by disassembling the clamp 202, which simplifies the disassembly and assembly process to a certain extent and improves the installation and maintenance efficiency.

[0048] In some embodiments, please combine Figures 1 to 5 The clamping member 202 includes two clamping arms 214 and a connecting arm 215. The two clamping arms 214 are respectively connected to the opposite ends of the connecting arm 215. The clamping arms 214 pass through the first clamping slot 205. Each clamping arm 214 is provided with a clamping portion 216. The clamping portion 216 is configured to be embedded in the second clamping slot 207. The two clamping portions 216 are configured to clamp the second connecting portion 206.

[0049] Specifically, when the connector 217 and the workpiece 219 are fixedly connected, the clamping portion 216 can be embedded in the second slot 207. The two clamping portions 216 clamp the second connector 206, so that after the second connector 206 is inserted into the insertion space 204 of the first connector 203, the clamping portion 216 clamps and secures the second connector 206 at the second slot 207, and the second connector 206 is unlikely to shake or will not shake. At the same time, because the clamping arm 214 passes through the first slot 205 and the clamping portion 216 is embedded in the second slot 207, the second connector 206 cannot be pulled out of the insertion space 204. This can improve the stability of the connection between the clamping member 202 and the connector 217 and the workpiece 219, thereby achieving a fixed connection between the connector 217 and the workpiece 219 via the first connector 203 and the second connector 206.

[0050] In the above embodiment, the stability of the connection between the joint 217 and the workpiece 219 by the clamp 202 can be improved, so that the joint 217 and the workpiece 219 are fixedly connected through the first connecting portion 203 and the second connecting portion 206 .

[0051] In some embodiments, please combine Figures 2 to 5 The shape of the clamping portion 216 is adapted to the shape of the periphery of the second connecting portion 206 where the second clamping groove 207 is provided.

[0052] Specifically, in one embodiment, please combine Figure 2 and Figure 3 The second connecting portion 206 is provided with a second card groove 207 whose periphery is cylindrical, and the clamping portion 216 is an arc shape adapted to the above-mentioned cylindrical shape, so that the clamping portion 216 can better fit with the second connecting portion 206. The fitting area between the clamping portion 216 and the second connecting portion 206 is large, which reduces or avoids the shaking of the second connecting portion 206 and makes the clamping of the second connecting portion 206 more stable.

[0053] It is understandable that in other embodiments, the periphery of the second connecting portion 206 where the second slot 207 is provided may be in other shapes, such as a square column, a polygonal column, etc., and is not limited to a cylindrical shape.

[0054] In the above embodiment, the clamping portion 216 can better clamp the second connecting portion 206 .

[0055] In some embodiments, please combine Figure 7 The first connection part 203 is a male head 227, and the male head 227 is provided with at least one limiting groove 208, which is separated from the second card groove 207. The water tank 201 includes at least one sealing ring 209, each sealing ring 209 is embedded in a corresponding limiting groove 208, and the sealing ring 209 is configured to seal and connect the first connection part 203 and the second connection part 206.

[0056] Specifically, please combine Figure 7 The connector 217 provided on the water tank 201 includes a first connecting portion 203, which may be a male connector 227. The male connector 227 is provided with at least one retaining groove 208, which is used to retain the sealing ring 209 so that it does not or is not easily displaced. The male connector 227 is provided with a second retaining groove 207, that is, the first connecting portion 203 is provided with a second retaining groove 207, and the second retaining groove 207 is separated from the retaining groove 208. Correspondingly, the workpiece 219 includes a second connecting portion 206, which is a female connector 226. That is, the second connecting portion 206 is provided with a first retaining groove 205. The retaining member 202 can penetrate the second connecting portion 206 of the workpiece 219 and fit it into the first connecting portion 203 of the connector 217, thereby securing the workpiece 219 and the connector 217.

[0057] Each sealing ring 209 is embedded in a corresponding limiting groove 208, so that the sealing ring 209 can be limited by the limiting groove 208, and the position of the sealing ring 209 will not or is not easy to change, which to a certain extent reduces the occurrence of sealing failure or reduced sealing due to displacement of the sealing ring 209.

[0058] The number of sealing rings 209 and limiting grooves 208 can be determined according to specific requirements (such as pressure requirements). Figure 2 In the embodiment, the joint 217 and the workpiece 219 are sealed and connected via two sealing rings 209 , and the two sealing rings 209 are respectively embedded in the two limiting grooves 208 in a one-to-one correspondence.

[0059] In one example, the sealing ring 209 may be a rubber ring or a silicone ring.

[0060] In the above embodiment, the sealing performance between the first connection portion 203 and the second connection portion 206 can be improved.

[0061] In some embodiments, please combine Figure 2 and Figure 3 , the sealing ring 209 is an O-type sealing ring 209.

[0062] Specifically, the first connection portion 203 is a male connector 227, and the second connection portion 206 is a female connector 226. The O-ring 209 has an O-shaped or circular cross-section. When squeezed by the first and second connection portions 203, 206, the O-ring 209 can extend and deform along the outer wall of the first and second connection portions 203, 206. This increases the contact area and bonding strength between the O-ring 209 and the first and second connection portions 203, 206, thereby improving sealing performance.

[0063] In the above embodiment, the O-ring 209 can provide better sealing performance.

[0082] The embodiment of the present invention provides a heating unit including the hydraulic module 200 of any one of the above embodiments.

[0083] Specifically, in one embodiment, the heating unit may include a heat source device and a heating terminal. The hydraulic module 200 is the core component of the heating unit. It organically combines the heat source device and the heating terminal to achieve heat generation, transmission and distribution. The hot water generated by the heat source device can be input into the water tank 201 in the hydraulic module 200 for storage. The hot water in the water tank 201 can be transported to each heating terminal, thereby providing heat for the entire heating unit. Among them, the heat source device may include but is not limited to an outdoor unit, a gas boiler, a solar water heater, etc. The heating terminal may include but is not limited to a domestic water tank, an area one system, and an area two system.

[0084] The external unit can include a heat pump system, which heats cold water into hot water and then transfers the hot water to the water tank 201 of the hydraulic module 200 for distribution. A gas furnace can use the heat generated by gas combustion to heat cold water to produce hot water. The hot water output by the gas furnace is then transferred to the water tank 201 of the hydraulic module 200 for distribution. A solar water heater can be connected to the hydraulic module via a pipeline. The solar water heater uses solar energy to directly heat cold water to produce hot water, which is then transferred to the water tank 201 of the hydraulic module 200 for distribution.

[0085] In one example, the heating terminal can be a domestic water tank. The water tank 201 in the hydraulic module 200 can deliver hot water to the coil within the domestic water tank. The hot water transfers heat through the coil to the domestic water in the domestic water tank, raising the temperature of the domestic water. The domestic water tank can be connected to a water outlet valve such as a faucet or showerhead, and the heated domestic water can be supplied to the user through the water outlet valve such as the faucet or showerhead.

[0086] In one example, the heating terminal can be a zone 1 system. The water tank 201 in the hydraulic module 200 can deliver hot water to the zone 1 system. The zone 1 system can include a heater suspended from the indoor ceiling, including but not limited to a fan coil unit (FCU). The fan coil unit can dissipate the heat from the hot water into the room, raising the indoor temperature.

[0087] In one example, the heating terminal can be a zone 2 system. The water tank 201 in the hydraulic module 200 can deliver hot water to the zone 2 system, which can include floor heating and / or radiators. The floor heating dissipates the heat from the hot water to the floor, while the radiators dissipate the heat from the hot water into the room, thereby raising the floor and room temperatures.
