Description

[0003] Existing heat pump indoor units typically only have one main control box for internal control and signal processing, while the distribution box is installed separately in the user's home. This separation means that the location of the distribution box needs to be found on-site during installation, resulting in complex wiring, difficult construction, and the need to inspect both the indoor unit and the user's distribution box separately during later maintenance. This is cumbersome, inefficient, and also presents problems such as excessively long wiring and numerous potential faults. Summary of the Invention

[0029] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0030] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0031] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0032] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0033] As shown in Figures 1 to 9, according to an embodiment of the present invention, a heating terminal hydraulic device 100 is proposed, which is mainly used in the heating water system of HVAC equipment, specifically a terminal for integrated centralized heating and domestic hot water. The heating terminal hydraulic device 100 of this embodiment can not only be used to connect user heating terminals (such as radiators, underfloor heating, or fan coil units), but also to connect external tap water pipelines and the client's second water storage unit (not shown in the figures).

[0034] The heating end hydraulic device 100 of this embodiment includes a body 1 and an electrical control component 2. The body 1 is used to install and protect the internal hydraulic pipes, control circuits, electrical control modules, and other components. The electrical control component 2 is installed inside the body 1 and includes a housing 21 and a power distribution unit 22 and a main control unit 23 disposed within the housing 21. A partition 24 is provided inside the housing 21, dividing the space inside the housing 21 into two independent first chambers 25 and second chambers 26. The power distribution unit 22 is disposed in the first chamber 25, and the main control unit 23 is disposed in the second chamber 26. By installing the power distribution unit 22 and the main control unit 23 in the same housing 21 and separating them by the partition 24, an integrated layout of power distribution and control is achieved, improving the structural compactness and functional synergy of the heating end hydraulic device 100.

[0035] On the one hand, the partition 24 can isolate the high-voltage power distribution unit 22 from the low-voltage main control unit 23, avoiding interference from high-voltage electric arcs or electromagnetic radiation to the main control board 231, and improving the safety and reliability of system operation. On the other hand, the partition 24 is provided with a wire hole 241, which is usually located at the lower part of the partition 24 or near the flip center of the outer casing 21, for the cables connecting the power distribution unit 22 and the main control unit 23 to pass through, realizing internal electrical connection, making the cable wiring path short and fixed, reducing signal attenuation and failure risk.

[0036] The heating end hydraulic device 100 of the present invention uses a partition 24 to divide the outer shell 21 of the electrical control component 2 into a first chamber 25 and a second chamber 26. The power distribution unit 22 and the main control unit 23 are respectively located in the first chamber 25 and the second chamber 26, so that the power distribution unit 22 and the main control unit 23 are integrated and installed in the outer shell 21. The integrated design of the electrical control component 2 effectively reduces the additional wiring and on-site positioning operations during installation, making subsequent maintenance more centralized and efficient, simplifying the overall installation process, and effectively improving the installation integration and construction convenience. The internal electrical connection between the power distribution unit 22 and the main control unit 23 is realized through the wiring hole 241 on the partition 24, which enhances the reliability of the system connection and improves the convenience of operation and maintenance and the overall operational stability.

[0037] In some embodiments of the present invention, the body 1 includes a main frame 11 and a first crossbeam 12 connected to the main frame 11. The upper end of the first crossbeam 12 maintains a certain distance from the top of the main frame 11. A first space 13 is defined between the first crossbeam 12 and the top of the main frame 11. The first space 13 is located in the upper region of the body 1. The electrical control component 2 is installed entirely within the first space 13. Its outer casing 21 is connected and fixed to the first crossbeam 12 and the top of the main frame 11 by bolts or snap-fit ​​structures, or indirectly connected by a support bracket. By centrally installing the electrical control component 2 within the first space 13, the functional zoning of the internal space of the body 1 is achieved, improving the structural compactness and reliability of the entire heating end hydraulic device 100.

[0038] In some embodiments of the present invention, along the front-rear direction of the body 1, the electronic control component 2 is disposed on the front side of the first space 13. That is, when the electronic control component 2 is installed in the first space 13, the outermost surface of the outer casing 21 facing the front of the body 1 is in the same plane as the front boundary of the first space 13, so that the front end of the outer casing 21 of the electronic control component 2 is flush with the front contour of the body 1, forming a flat appearance without protrusions. When it is necessary to debug or repair the internal components of the power distribution unit 22 or the main control unit 23, the maintenance personnel can directly access the installation area of ​​the front end of the outer casing 21 from the front of the body 1 without having to go deep into the body 1 or go around to the rear, shortening the operation path and improving maintenance efficiency.

[0039] In some embodiments of the present invention, the partition 24 is vertically arranged along the height direction of the body 1, and the first chamber 25 and the second chamber 26 are arranged side by side along the left-right direction of the body 1, with the first chamber 25 located on the left and the second chamber 26 located on the right. The side-by-side arrangement makes the two chambers closely adjacent in the width direction of the body 1, which not only avoids the waste of height space caused by stacking vertically, but also achieves horizontal isolation between the high-voltage and low-voltage areas through the vertical separation of the partition 24, thus optimizing the internal space utilization of the electronic control component 2.

[0040] In some embodiments of the present invention, the electrical control assembly 2 further includes a first cover plate 27. The front side of the first chamber 25 has a first opening, which provides maintenance personnel with a channel to directly access the power distribution unit 22 inside the chamber. The first cover plate 27 is fixed to the front side of the outer casing 21 by means of hinges, snaps, or bolts. The first cover plate 27 is used to open or close the first opening. Under normal conditions, the first chamber 25 is closed to protect the internal electrical components. When the power distribution unit 22 needs to be inspected or debugged, maintenance personnel can directly disassemble or open the first cover plate 27 and quickly access the power distribution unit 22 inside the first chamber 25 through the first opening without disassembling the entire outer casing 21 or other unrelated parts, thus improving the maintenance efficiency and operational safety of the high-voltage area.

[0041] The electrical control assembly 2 also includes a second cover plate 28. The front of the second chamber 26 has a second opening, providing a direct access point for maintenance of the main control unit 23 within the second chamber 26. The second cover plate 28 is fixed to the front of the outer casing 21 via hinges, clips, or bolts. The second cover plate 28 is used to open or close the second opening. Under normal conditions, it protects the low-voltage components within the chamber. When signal detection or maintenance of the main control unit 23 is required, maintenance personnel only need to open the second cover plate 28 and operate the main control unit 23 directly through the second opening, without touching the high-voltage components within the first chamber 25, thus avoiding the risk of high-voltage interference and simplifying the maintenance process in the low-voltage area. The split cover plate structure achieves physical isolation and functional independence between the first chamber 25 and the second chamber 26, ensuring the operational independence of the power distribution unit 22 and the main control unit 23 under integrated installation conditions.

[0042] In some embodiments of the present invention, the lower edge of the outer shell 21 is rotatably connected to the first crossbeam 12. The first crossbeam 12 provides a stable rotation fulcrum for the flipping structure. Multiple first hinges are provided on the first crossbeam 12, spaced apart along its length. One end of each hinge is connected to the first crossbeam 12, and the other end is connected to the outer shell 21, allowing the outer shell 21 to flip up and down relative to the main frame 11 between a stowed position and an unfolded position, using the first hinges as rotation axes. In the stowed position, the outer shell 21 is located within the first space 13, and its front surface is flush with the front side of the body 1, protecting the internal components and maintaining a clean appearance on the front of the body 1. When operation is required, the outer shell 21 can flip downwards around the first crossbeam 12, transitioning from the stowed position to the unfolded position. During this process, the outer shell 21 flips away from the main frame 11 until a preset maximum flipping angle is reached, which is 160°-180°. When the outer casing 21 is in the unfolded position, it flips downwards to be outside the first space 13, so that the water pump, valve and other devices that were originally covered by the outer casing 21 inside the body 1 are fully exposed, which makes it easier for operators to carry out maintenance and shortens the operation time and steps of maintenance.

[0043] In some embodiments of the present invention, a first hook-on portion 15 is provided on the top of the main frame 11, and a second hook-on portion 29 is provided on the outer casing 21. The first hook-on portion 15 and the second hook-on portion 29 can be configured as L-shaped hooks or perforated hanging plates, etc. During installation, the second hook-on portion 29 is hooked onto the first hook-on portion 15 to form a preliminary mechanical locking position. At the same time, both the first hook-on portion 15 and the second hook-on portion 29 are provided with screw holes. By inserting screws, the outer casing 21 is rigidly fixed to the top of the main frame 11, ensuring that the casing is stable and does not shake during daily use.

[0044] When the outer casing 21 needs to be flipped for maintenance, the operator first removes the connecting screws. At this time, the outer casing 21 is kept in a hooked state with the top of the main frame 11 through the first hook part 15 and the second hook part 29, so that the outer casing 21 can remain in the original position after the screws are removed. This avoids the risk of the outer casing 21 suddenly falling after the restraints are removed, prevents the outer casing 21 from injuring the operator or damaging the internal components, and improves the safety of the maintenance process.

[0045] In some embodiments of the present invention, a limiting rope 3, specifically a steel wire rope, is provided between the outer shell 21 and the main frame 11. The two ends of the steel wire rope are connected to the outer shell 21 and the main frame 11, respectively. The steel wire rope is used to limit the maximum flipping angle of the outer shell 21. When the outer shell 21 is in the retracted position, the steel wire rope is in a slack state. When the outer shell 21 flips downwards, the steel wire rope is gradually straightened as the box rotates. Since the steel wire rope itself has no elastic expansion or contraction, its length is fixed. When it is stretched to its limit length, it rigidly prevents the outer shell 21 from continuing to flip at a larger angle, thereby limiting the maximum flipping angle to 160°.

[0046] If it is necessary to further expand the rotation range, the operator can remove the wire rope in advance. At this time, the outer shell 21 loses the rigid limit constraint of the wire rope and is only limited by its own mechanical structure, such as the hinge rotation limit or the physical contact between the outer shell 21 and the main frame 11. The maximum rotation angle can be increased to 180°.

[0047] In some embodiments of the present invention, the heating end hydraulic device 100 further includes a water tank 9, and the first crossbeam 12 includes a connecting portion 121. The connecting portion 121 extends along the left-right direction of the body 1 and is connected to the main frame 11. The front end of the water tank 9 protrudes forward beyond the front surface of the connecting portion 121. Specifically, the plane where the front end of the water tank 9 is located extends beyond the plane where the front end of the connecting portion 121 is located in the horizontal forward direction, realizing a staggered arrangement between the water tank 9 and the first crossbeam 12 in the front-rear direction. This makes full use of the space on the front side of the first crossbeam 12, thereby effectively shortening the overall size of the body 1 in the front-rear direction while ensuring that the water tank 9 has sufficient volume, making the device structure more compact.

[0048] In some embodiments of the present invention, the first crossbeam 12 further includes a limiting part 122. The connecting part 121 is provided with limiting parts 122 at both ends in the left and right directions. Each limiting part 122 is arranged perpendicularly to the connecting part 121 and extends horizontally forward from the front end of the connecting part 121, so that in the front and back directions, the front end of the limiting part 122 is located at the front end of the water tank 9.

[0049] When the entire electronic control component 2 flips downwards, the front end of the limiting part 122 abuts against the outer casing 21 to limit the flipping angle of the electronic control component 2. Specifically, since the front end of the limiting part 122 is located at the front end of the water tank 9, when the electronic control component 2 flips downwards, the front end of the limiting part 122 abuts against the outer casing 21 before the outer casing 21 contacts the water tank 9, thereby blocking the outer casing 21 from touching the water tank 9 before it does, effectively preventing the electronic control component 2 from colliding with the water tank 9 during the downward flipping process and ensuring operational safety.

[0050] In some embodiments of the present invention, the power distribution unit 22 includes a circuit breaker 221 and a terminal block 222. The circuit breaker 221 and the terminal block 222 are disposed in the first chamber 25. The outer casing 21 is provided with a first wire passage hole 211 extending along the height direction of the body 1 at the bottom of the first chamber 25. The first wire passage hole 211 is located at the bottom left of the outer casing 21. The heating household hydraulic device 100 also includes a main power line and a first side plate 14 installed on the main frame 11. The first side plate 14 is disposed on the back of the outer casing 21. A second wire passage hole 141 is provided on the first side plate 14. One end of the main power line is used to connect to an external power source. The other end of the main power line passes through the second wire passage hole 141 and the first wire passage hole 211 in sequence and is connected to the circuit breaker 221. Through this wiring structure, the main power line passes through the second wire hole 141 on the first side plate 14 and the first wire hole 211 on the outer casing 21 twice, forming the introduction path from the external power supply to the circuit breaker 221 of the power distribution unit 22. This not only ensures the protection and reliability of the power supply introduction, but also makes the overall wiring clear and facilitates subsequent inspection and replacement.

[0051] In some embodiments of the present invention, along the height direction of the body 1, the circuit breaker 221 is disposed above the terminal block 222; the distance between the upper end face of the circuit breaker 221 and the plane containing the top of the housing 21 is greater than or equal to 60 mm, and / or, the distance between the lower end face of the circuit breaker 221 and the upper end face of the terminal block 222 is greater than or equal to 60 mm, and / or, the distance between the lower end face of the terminal block 222 and the plane containing the bottom of the housing 21 is greater than or equal to 110 mm.

[0052] To balance electrical safety, heat dissipation performance, and ease of operation and maintenance, specific designs were implemented for the vertical spacing between key components. The use of "and / or" indicates that the three spacing conditions can be used individually or in any combination. In this embodiment, the three spacing combinations are as follows: the spacing L1 between the upper surface of the circuit breaker 221 and the top plane of the housing 21 is greater than or equal to 60mm; the spacing L2 between the lower surface of the circuit breaker 221 and the upper surface of the terminal block 222 is greater than or equal to 60mm; and the spacing L3 between the lower surface of the terminal block 222 and the bottom plane of the housing 21 is greater than or equal to 110mm. By setting these three spacings, the cables are prevented from being bent by external forces or rubbing against the housing 21, ensuring that the cables maintain natural bending and loose routing at the top, middle, and bottom. This reduces the risk of friction between the cables and the surface of the housing 21, improving the durability and safety of the wiring inside the power distribution unit 22.
