[0032] In related technologies, heating units and other equipment require water tanks to collect, buffer, and distribute water. These tanks are typically large, and when installed on a chassis with screws, they must be moved several times to align with the chassis holes. This is laborious and time-consuming, and can also wear away the chassis' paint and cause rust.

[0033] See also Figure 1 A water tank assembly 100 provided in an embodiment of the present invention includes a chassis 10, a mounting member 12 and a water tank 14. The chassis 10 is provided with a first connecting portion 16, the mounting member 12 is provided on the water tank 14, the mounting member 12 is provided with a second connecting portion 18, the second connecting portion 18 is provided with a first through hole 20, and the wall of the first through hole 20 is provided with a notch 22 connected to the first through hole 20. The first connecting portion 16 passes through the first through hole 20 to position the water tank 14 and the chassis 10, and the notch 22 is configured to allow the first connecting portion 16 to enter the first through hole 20.

[0034] In the above-mentioned water tank assembly 100, the water tank 14 is fixedly connected to the mounting member 12. When the water tank 14 is installed on the chassis 10, the first connecting portion 16 and the second connecting portion 18 cooperate to position the water tank 14 and the chassis 10, saving time and effort, and reducing the inconvenience of installation and wear on the bottom of the water tank 14 caused by repeated movement of the water tank 14 when the water tank 14 is aligned with the chassis 10.

[0035] Specifically, the water tank assembly 100 can be applied to, but not limited to, a hydraulic module 200. The hydraulic module 200 can be applied to a heating unit. In one embodiment, the heating unit may include an outdoor unit, a domestic water tank, a gas boiler, a zone 1 system, and a zone 2 system. The hydraulic module 200 can be connected to the outdoor unit, the domestic water tank, the gas boiler, the zone 1 system, and the zone 2 system via pipes. The outdoor unit may include a heat pump system, which can heat cold water into hot water and then pass the hot water into the hydraulic module 200 for distribution.

[0036] The gas furnace can use the heat generated by the combustion of gas to heat cold water to form hot water. The hot water output by the gas furnace is input into the hydraulic module 200 for distribution.

[0037] Optionally, the heating unit further comprises a solar water heater, and the hydraulic module 200 is connected to the solar water heater via a pipeline. The solar water heater can directly heat water using solar energy to form hot water, which can be transmitted to the hydraulic module 200 for distribution.

[0038] First, the hydraulic module 200 delivers hot water to the coil within the domestic water tank. The hot water then transfers heat through the coil to the domestic water in the tank, raising the temperature of the domestic water. The domestic water tank can be connected to a faucet, showerhead, or other outlet valve, and the heated domestic water can be supplied to the user through these outlet valves.

[0039] Secondly, 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 of the hot water into the room, raising the indoor temperature.

[0040] Thirdly, 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 ground, and the radiators dissipate the heat from the hot water into the room, thereby raising the ground and indoor temperatures.

[0041] The hydraulic module 200 may include a buffer water tank, which is connected to the solar water heater, outdoor unit, domestic water tank, gas furnace area 1 system and area 2 system through pipelines to collect, buffer and distribute water used in each part.

[0042] The water tank 14 may include, but is not limited to, a buffer water tank and a domestic water tank.

[0043] The water tank assembly 100 includes a water tank 14, a mounting member 12 and a chassis 10. The water tank 14 is fixedly connected to the mounting member 12. A first connecting portion 16 is provided on the chassis 10. A second connecting portion 18 is provided on the mounting member 12. The mounting member 12 is fixedly connected to the water tank 14 and the chassis 10.

[0044] A first through hole 20 is provided on the second connecting portion 18, and a notch 22 communicating with the first through hole 20 is provided on the surrounding wall of the first through hole 20. The first connecting portion 16 enters the first through hole 20 through the notch 22, so that the positions of the water tank 14 and the chassis 10 can be positioned by cooperating with the second connecting portion 18.

[0045] When the water tank 14 and the chassis 10 are installed, the water tank 14 can be lifted manually or by a lifting mechanism so that the first connecting portion 16 is aligned with the position of the first through hole 20, or the first connecting portion 16 is inserted into the first through hole 20 through the notch 22. In this way, the positions of the water tank 14 and the chassis 10 can be positioned, making it easier to quickly install the water tank 14 on the chassis 10, thereby reducing frequent friction between the bottom of the water tank 14 and the chassis 10 when the water tank 14 and the chassis 10 are aligned, which may cause the chassis 10 to peel off and become prone to rust.

[0046] See also Figure 1 In some embodiments, the chassis 10 includes a body 24 , and the first connecting portion 16 is disposed on the body 24 .

[0047] In this way, the first connecting portion 16 can be easily positioned on the second connecting portion 18 .

[0048] Specifically, the first connecting portion 16 is fixedly mounted on the chassis 10, facilitating alignment and installation of the second connecting portion 18 with the first connecting portion 16 when the water tank 14 is installed. The first connecting portion 16 is fixed to the side of the body 24 facing the water tank 14. During installation, the water tank 14 can be lifted manually or by a hoisting mechanism. The first connecting portion 16 and the first through-hole 20 on the second connecting portion 18 are aligned, and the second connecting portion 18 is inserted through the notch 22 or directly through the first through-hole 20. The water tank 14 is then placed on the chassis 10, completing the installation of the water tank 14 and chassis 10.

[0049] Optionally, the first connection portion 16 may be welded to the body 24 , or the first connection portion 16 may be connected to the body 24 by adhesive connection or threaded connection.

[0050] See also Figures 2 to 5 In some embodiments, the mounting member 12 includes a first portion 26 and a second portion 28 , the first portion 26 is connected to the second portion 28 , the first portion 26 is fixedly connected to the water tank 14 , and the second connecting portion 18 is disposed on the second portion 28 .

[0051] In this way, the mounting member 12 is conveniently fixedly connected to the water tank 14 and the chassis 10 .

[0052] Specifically, the mounting member 12 includes a first portion 26 and a second portion 28. The first portion 26 connects to the second portion 28 and forms a predetermined angle therebetween. The first portion 26 of the mounting member 12 is first fixedly mounted to the water tank 14, and then the second connecting portion 18 on the second portion 28 is aligned with the first connecting portion 16. In this manner, the first portion 26 secures the mounting member 12 to the water tank 14, while the second portion 28 securely connects the water tank 14 to the chassis 10. This prevents interference during installation, facilitating installation.

[0053] In one embodiment, Figure 2 and Figure 4 As shown, the first portion 26 is connected to the second portion 28 to form an "L"-shaped mounting member 12, which facilitates the fixed connection between the first portion 26 and the side wall of the water tank 14. After the first portion 26 is installed to the side wall of the water tank 14, the water tank 14 is placed on the chassis 10, and the second portion 28 can contact the chassis 10, thereby facilitating the connection between the second portion 28 and the chassis 10.

[0054] Optionally, the first portion 26 and the second portion 28 may be fixedly connected by welding, riveting, gluing, or the like.

[0055] Optionally, the first portion 26 and the second portion 28 may be formed by an integral molding process.

[0056] See also Figure 1 and Figure 6 In some embodiments, the water tank assembly 100 includes a fixing member 30, which defines a second through hole 32. The first connecting portion 16 is provided with a thread, and the hole wall of the second through hole 32 is provided with an internal thread matching the thread on the first connecting portion 16. The second through hole 32 passes through the first connecting portion 16 to fix the mounting member 12 to the chassis 10.

[0057] In this way, the first connecting portion 16 and the mounting member 12 can be connected by threads, which is simple in connection and easy to maintain.

[0058] Specifically, the first connecting portion 16 is provided with an external thread, the fixing member 30 is provided with a second through hole 32, and the hole wall of the second through hole 32 is provided with an internal thread matching the thread on the first connecting portion 16. The water tank 14 is fixedly connected to the mounting member 12, and after the position on the chassis 10 is determined by the first through hole 20 on the mounting member 12, the second through hole 32 on the fixing member 30 is screwed into the first connecting portion 16 to fix the water tank 14 and the chassis 10.

[0059] In one embodiment, the first connection portion 16 includes a stud and the fixing member 30 includes a nut. The stud is welded to the chassis 10, the first through hole 20 passes through the stud, and the nut is screwed into the stud to fix the water tank 14 to the chassis 10.

[0060] See also Figure 1 In some embodiments, the mounting member 12 further includes a washer mounted between the fixing member 30 and the second portion 28 .

[0061] In this way, the fixing area of ​​the fixing member 30 to the mounting member 12 can be increased by the washer. At the same time, the washer can protect the connection between the mounting member 12 and the first connecting portion 16 .

[0062] Optionally, the gasket includes a flat gasket 34. The size of the flat gasket 34 can be larger than the size of the fixing member 30. The flat gasket 34 is placed between the fixing member 30 and the second connecting part 18. After the fixing member 30 is fixedly connected to the first connecting part 16, the fixing member 30 presses against the flat gasket 34, and the second connecting part 18 can be fixed between the flat gasket 34 and the chassis 10. Thus, the fixing member 30 can increase the fixing area of ​​the second connecting part 18 through the flat gasket 34.

[0063] At the same time, the flat washer 34 protects the surface of the second connecting portion 18 from being scratched by the fixing member 30. During installation, the fixing member 30 applies pressure to the second connecting portion 18. Without the washer, this pressure could damage the surface of the second connecting portion 18. The washer distributes this pressure, thereby protecting the integrity of the second connecting portion 18.

[0064] In addition, the flat washer 34 can disperse the pressure of the fixing member 30 on the second connecting portion 18, making the pressure distribution more uniform and avoiding damage caused by excessive local pressure.

[0065] Optionally, the washer also includes a spring washer 35. The spring washer 35 provides additional tightening force, preventing the fixture 30 from loosening during installation or under vibration, impact, or other conditions. When the fixture 30 is tightened, the elastic portion of the spring washer 35 is compressed, generating a force that resists loosening. When an external force attempts to loosen the fixture 30, the spring washer 35 returns to its original shape, maintaining the tightness of the connection. Thus, the spring washer 35 significantly improves the fastening performance and reliability of the fixture 30.

[0066] See also Figure 7 In some embodiments, the surrounding wall of the first through hole 20 includes an arc segment 36, and the distance H between the center of the first connecting portion 16 and the center of the arc segment 36 is in the range of [2 mm, 5 mm].

[0067] In this way, the position of the first connecting portion 16 can be determined according to the position of the mounting member 12 on the water tank 14 .

[0068] Specifically, the surrounding wall of the first through hole 20 includes an arc segment 36, and the distance H between the center of the first connecting portion 16 and the center of the arc segment 36 has a value in the range of [2 mm, 5 mm]. For example, the distance H between the center of the first connecting portion 16 and the center of the arc segment 36 can be 2 mm, 2.3 mm, 2.6 mm, 3 mm, 3.5 mm, 3.8 mm, 4 mm, 4.3 mm, 4.7 mm, or 5 mm. Alternatively, the distance H between the center of the first connecting portion 16 and the center of the arc segment 36 can be any other value within the range of [2 mm, 5 mm].

[0069] If the distance H between the center of the arc segment 36 of the first through hole 20 and the center of the first connecting portion 16 is less than 2 mm, it will be difficult to align the first connecting portion 16 with the first through hole 20 during installation. If the distance H between the center of the arc segment 36 of the first through hole 20 and the center of the first connecting portion 16 is greater than 5 mm, the distance between the first through hole 20 and the first connecting portion 16 will be too large, and the fixing member 30 will be unable to fix the mounting portion and the first connecting portion 16, or the fixation will be unstable, causing the water tank 14 to wobble on the chassis 10.

[0070] In one embodiment, the water tank assembly 100 includes a mounting member 12 , and a distance H between the center of the arc segment 36 of the first through hole 20 and the center of the first connecting portion 16 is in a range of [2 mm, 5 mm].

[0071] In one embodiment, the water tank assembly 100 includes two mounting members 12 , and the distance H between the center of the arc segment 36 of each first through hole 20 and the center of the corresponding first connecting portion 16 is in the range of [2 mm, 5 mm].

[0072] In one embodiment, Figure 8 As shown, the water tank assembly 100 includes multiple (more than two) mounting members 12. In this case, the center of the arc segment 36 of the first through hole 20 on each mounting member 12 can form a circle O1, and the center of each first connecting portion 16 can form a circle O2. The distance between the center of the arc segment 36 of the first through hole 20 and the center of the first connecting portion 16 is the difference between the radii of circle O2 and circle O1. In other words, the difference between the radii of circle O2 and circle O1 has a value range of [2 mm, 5 mm]. It should be noted that the radius of circle O2 is greater than the radius of circle O1.

[0073] See also Figure 9In some embodiments, the surrounding wall of the first through hole 20 includes two symmetrical arc segments 36, and the distance between the center of the arc segment 36 and the center D1 of the first through hole 20 is greater than or equal to half of the diameter D0 of the first connecting portion 16, and less than or equal to twice the diameter D0 of the first connecting portion 16.

[0074] In this way, the first connection portion 16 and the first through hole 20 are more easily positioned.

[0075] Specifically, if Figure 9 As shown, the first connecting portion 16 includes a stud with a circular cross-section, and the surrounding wall of the first through hole 20 includes two symmetrical arc segments 36. The distance D1 between the center of the arc segment 36 and the center of the first through hole 20 is greater than or equal to half of the diameter D0 of the first connecting portion 16, and less than or equal to twice the diameter D0 of the first connecting portion 16, that is, D0 / 2≤D1≤2D0.

[0076] During installation, the first connecting portion 16 enters the first through hole 20 through the notch 22. At this time, the water tank 14 is rotated so that the first connecting portion 16 is close to one of the two arc segments 36. Subsequently, the first connecting portion 16 and the mounting member 12 are fixed by the fixing member 30 to fix the water tank 14 on the chassis 10.

[0077] If the distance between the center of the arc segment 36 and the center D1 of the first through hole 20 is less than half the diameter D0 of the first connecting portion 16, it will be difficult to align the first connecting portion 16 with the first through hole 20 during installation. If the distance between the center of the arc segment 36 and the center D1 of the first through hole 20 is greater than twice the diameter D0 of the first connecting portion 16, the distance between the first through hole 20 and the first connecting portion 16 will be too large, and the fixing member 30 will be unable to fix the mounting portion and the first connecting portion 16, or the fixation will be unstable, causing the water tank 14 to wobble on the chassis 10.

[0078] In some embodiments, along the vertical direction, the distance L between the bottom surface of the water tank 14 and the contact surface between the mounting member 12 and the chassis 10 is in the range of [3 mm, 10 mm].

[0079] In this way, there is a certain distance between the contact surface of the mounting member 12 and the chassis 10 and the bottom surface of the water tank 14. When the water tank 14 is installed on the chassis 10 through the mounting member 12, the contact between the bottom surface of the water tank 14 and the chassis 10 can be reduced, thereby reducing the wear between the two.

[0080] Specifically, if Figure 1 As shown, the distance L between the bottom surface of the water tank 14 and the contact surface of the mounting member 12 and the chassis 10 can be 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, or any other value within the range of [3 mm, 10 mm].

[0081] If the distance L between the bottom surface of the water tank 14 and the contact surface between the mounting member 12 and the chassis 10 is less than 3 mm, it will be difficult to drain the water accumulated at the bottom of the water tank 14; if the distance L between the bottom surface of the water tank 14 and the contact surface between the mounting member 12 and the chassis 10 is greater than 10 mm, it will affect the stability of the installation of the water tank 14.

[0082] See also Figure 7 and Figure 9 In some embodiments, the water tank assembly 100 includes a plurality of mounting members 12 , and the plurality of mounting members 12 are evenly distributed along the circumference of the water tank 14 .

[0083] In this way, the installation and fixation of the water tank 14 can be made more stable and firm. At the same time, multiple installation parts 12 are installed at the same time, and the force is evenly distributed, which has a protective effect on the installation parts 12 and the chassis 10.

[0084] Specifically, the water tank assembly 100 includes a plurality of mounting members 12. For example, the water tank assembly 100 may include two mounting members 12, which are symmetrically arranged on both sides of the water tank 14. For example, the water tank assembly 100 may include three mounting members 12, which are evenly distributed along the circumference of the water tank 14.

[0085] The multiple mounting members 12 can evenly withstand the pressure from the water tank 14 , so that the forces on the mounting members 12 and the chassis 10 can be dispersed and uniform, and the mounting members 12 and the first connecting portion 16 connected to the mounting members 12 can be effectively protected.

[0086] See also Figure 10 The hydraulic module 200 provided in the embodiment of the present invention includes the water tank assembly 100 of any of the above embodiments.

[0087] In the above-mentioned hydraulic module 200, the water tank 14 is fixedly connected to the mounting member 12. When the water tank 14 is installed on the chassis 10, the first connecting portion 16 and the second connecting portion 18 cooperate to position the water tank 14 and the chassis 10, saving time and effort, and reducing the inconvenience of installation and wear on the bottom of the water tank 14 caused by repeated movement of the water tank 14 when the water tank 14 is aligned with the chassis 10.

[0088] Specifically, the hydraulic module 200 can be applied to, including but not limited to, heating units. The hydraulic module 200 can deliver hot and cold water. In one embodiment, the hydraulic module 200 can distribute the hot water generated by the outdoor unit, gas boiler, and solar water heater to the area one system, area two system, and domestic water tank, thereby increasing the temperature of the space where the area one system and area two system are located, and increasing the temperature of the domestic water in the domestic water tank. In one embodiment, the hydraulic module 200 can distribute the cold water generated by the outdoor unit and solar water heater to the area one system, area two system, and domestic water tank, thereby reducing the temperature of the space where the area one system and area two system are located, and reducing the temperature of the domestic water in the domestic water tank.

[0089] The embodiment of the present invention provides a heating unit including the hydraulic module 200 of any one of the above embodiments.

[0090] In the above-mentioned heating unit, the water tank 14 is fixedly connected to the mounting part 12. When the water tank 14 is installed on the chassis 10, the first connecting part 16 and the second connecting part 18 cooperate to position the water tank 14 and the chassis 10, saving time and effort, and reducing the repeated movement of the water tank 14 when the water tank 14 is aligned with the chassis 10, which causes installation inconvenience and wear on the bottom of the water tank 14.

[0091] Specifically, in one embodiment, the heating unit may include an outdoor unit, a domestic water tank, a gas boiler, a zone 1 system, and a zone 2 system. The hydraulic module 200 may be connected to the outdoor unit, the domestic water tank, the gas boiler, the zone 1 system, and the zone 2 system via pipes. The outdoor unit may include a heat pump system, which may heat cold water into hot water and pass the hot water into the hydraulic module 200 for distribution to the zone 1 system and the zone 2 system.

[0092] The gas furnace can use the heat generated by the combustion of gas to heat cold water to form hot water. The hot water output by the gas furnace is input into the hydraulic module 200 for distribution to the area 1 system and the area 2 system.

[0093] Optionally, the heating unit also includes a solar water heater, to which hydraulic module 200 is connected via a pipeline. The solar water heater utilizes solar energy to generate electricity, which is then used to heat cold water to form hot water. The hot water is then transferred to hydraulic module 200 for distribution to the area 1 system and the area 2 system.
