[0024] The following is a further detailed description of the specific implementation of the present utility model in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present utility model, but are not intended to limit the scope of the present utility model.

[0025] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be pipeline connection, pipe connection, or equipment connection; it can be split connection or integral connection; it can be direct connection or indirect connection through an intermediate medium, it can be the connection between the inside of two components or the outside of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] Example 1: Figure 1 As shown, the figure exemplarily shows an integrated fan coil structure, which includes a protective body 1, an integrated combination body 2, a maintenance component 3, and a fan coil 4.

[0027] In the embodiment of the present application, the protective body 1 includes an outer shell structure 11 , a bottom support plate 12 , a support structure 13 , and a panel 14 , wherein the support structure 13 is located inside the protective body 1 .

[0028] The integrated complex 2 includes an elastic device 21 , an electric control valve body 22 , a filter device 23 , a radially slidable component 24 , a lead-in port 25 , a fixing clamp 26 , a fan coil inlet 27 , a fan coil outlet 28 , a condensation port 29 , and an integrated water receiving device 210 .

[0029] The inspection component 3 includes a hidden visible panel 31, a fixed frame 32, and an inspection switch 33. The hidden visible panel 31 is made of a transparent rigid material and has a free opening and closing function. The maximum opening and closing angle is 90°.

[0030] The fan coil 4 is connected to the filter device 23, the elastic device 21 and the radially slidable component 24 through the fan coil inlet 27, and is connected to the electric control valve body 22, the elastic device 21 and the radially slidable component 24 through the fan coil outlet 28. The integrated water receiving device 210 is located at the bottom position and is used to collect condensed water. It can be integrated or split with the water receiving tray in the existing vertical surface-mounted fan coil and horizontal fan coil, and the condensed water is discharged through the condensation port 29.

[0031] The radially slidable component 24 includes a vibration-damping and dust-proof kit 241, a radial fixing part 242, and an axial fixing device 243; the vibration-damping and dust-proof kit 241 is sleeved on the outside of the radial fixing part 242, and the radial fixing part 242 is installed at the reserved hole position on the outer shell structure 11; one side of the vibration-damping and dust-proof kit 241 contacts the panel of the outer shell structure 11, and the other side contacts the inner side surface of the outer shell structure 11, and the material of the vibration-damping and dust-proof kit 241 is a flexible flame-retardant material; the axial fixing device 243 is arranged at a circumferentially uniform position of the radial fixing part 242, and is fixed in a circumferential direction to the reserved holes on the panel of the outer shell structure 11 through fixing bolts.

[0032] Furthermore, the integrated water receiving device 210 located at the bottom position and the existing fan coil unit can be combined in an integrated manner or a split manner. In the integrated combination, the fan coil unit and the bottom of the integrated fan coil unit structure share the water receiving device, and all condensed water is discharged through the condensation port 29; the split combination fan coil unit overflows the condensed water into the integrated water receiving device 210 through the overflow port, and is finally discharged through the condensation port 29. At this time, the two are connected by a fixing device.

[0033] The utility model integrates the elastic device, filtering device, integrated water receiving device and electric control device used in the installation process of the existing fan coil water pipe into a whole. The whole device can be flexibly combined with the existing horizontal and vertical exposed fan coils in a split or integrated manner, which greatly reduces the installation difficulty and subsequent maintenance cost of the fan coil water pipe system. In addition, during the installation of the fan coil, the exposed part only has the pipe and no valve components are installed between them, which makes the exposed part of the pipe installation more concise and beautiful. At the same time, the modular and integrated structural setting can be pressure tested as a whole with the fan coil, so that installation quality problems and quality risks can be discovered and prevented in advance, which greatly improves the installation quality of the fan coil water pipe and the stability of the subsequent operation of the entire system.

In the prior art, the flexible connection device 21, the electric control valve 22, and the filter device 23 all need to be installed separately, and each needs to have its own installation process, which has many processes and many hidden dangers of water leakage. At the same time, the water receiving tray has the disadvantages of easy blockage due to impurities in the overflow port and easy blockage due to freezing in winter. The present application optimizes and integrates the above-mentioned devices and manufactures them into a whole, and at the same time uses the protective body 1 to optimize the insulation and antifreeze of the water pipe system, so as to maximize the integration of the functions of each component and reduce the impact of energy loss on the reliability of system operation.

[0035] In this embodiment, the protective body 1 also includes a heat insulation structure and an energy reflection structure located inside the outer shell structure 11. The heat insulation structure is made of rubber and plastic material with a thickness of not less than 25 mm. The energy reflection structure is covered with a reflective coating on the front and an opaque coating on the back, and an anti-corrosion coating is sprayed on the surface of the outer shell structure 11. The heat insulation structure and the energy reflection structure inside the outer shell structure 11 can reduce the energy loss during the operation of the integrated module, and the inlet and outlet pipelines and valve components can operate stably without additional heat insulation measures.

[0036] Embodiment 3: As a preferred embodiment of the present application, the integrated fan coil structure also includes a maintenance component 3, which includes a hidden visible panel 31, a fixed frame 32, and a maintenance switch 33.

The support structure 13 plays a load-bearing role inside the outer shell structure 11 and meets the mechanical requirements during transportation and installation. The support material is stainless steel or fiberglass. The support structure 13 is arranged at both ends of the electric control valve 22 and the filter device 23, and is fixed by a fixing clamp 26; at the same time, a transverse support structure is arranged to fix the electric control valve 22 and the filter device 23 transversely.
