Description

Technical Field

[0001] The present application relates to the technical field of central air-conditioning systems, and in particular to a quick connection structure between a fan coil unit and an air outlet. Background Art

[0002] The fan coil unit is referred to as a fan coil. It is one of the terminal devices of the air conditioning system, which consists of a small fan, a motor and a coil (air heat exchanger). When chilled water or hot water flows through the coil tube, it exchanges heat with the air outside the tube, so that the air is cooled, dehumidified or heated to adjust the indoor air parameters. It is a commonly used cooling and heating terminal device.

[0003] At present, horizontal installation units are mostly hidden on the ceiling, and there are two air supply methods: upper side supply and ceiling downward air supply. If the side supply method is adopted, a low static pressure fan coil unit can be selected, and the unit outlet is directly connected to the double-layer louver air outlet; if the ceiling is used for downward air supply, a high static pressure fan coil unit should be selected, and the unit air outlet is directly connected to the air outlet, and several diffusers are connected on it to supply air downward.

[0004] However, for fan coil units that supply air, when the fan coil units are directly connected to the air outlets, the air outlets are fixed to the fan coil units by means of rivets or screws. This traditional installation method mainly has the following problems:

[0005] 1) The installation speed is slow and the labor cost is high;

[0006] 2) When the fan coil unit is installed on the ceiling, there is no space on the top of the fan coil unit where the air outlet is connected to the air outlet, so the electric drill cannot be used to fix it, which may cause vibration and noise in the later stage;

[0007] 3) Cleaning the heat exchange fins of the fan coil requires removing the screws, which is troublesome and inconvenient.

[0008] Therefore, exploring an efficient, fast and quality-assured connection method can better meet market demand. Utility Model Content

[0009] In order to solve the problems existing in the prior art, the present application provides a quick connection structure between a fan coil unit and an air outlet, which can quickly realize the installation and disassembly of the fan coil unit and the air outlet, thereby achieving the purpose of facilitating practical use.

[0010] In order to achieve the above objectives, this application adopts the following technical solutions:

[0011] The quick connection structure between the fan coil unit and the air outlet comprises a blocking member arranged on the outside of the air outlet and a rotating handle arranged on the inside of the air outlet. When the rotating handle is rotated, the rotating handle is used to press on the inside of the air inlet and outlet of the fan coil unit so that the end of the air inlet and outlet of the fan coil unit fits tightly with the blocking member.

[0012] By adopting the above technical solution, after the installation side of the air outlet is installed into the air inlet and outlet of the fan coil unit, the rotating handle inside the air outlet is manually turned, and one end of the rotating handle is pressed against the inner side of the air inlet and outlet of the fan coil unit, so that the air inlet and outlet ends of the fan coil unit are tightly fitted with the blocking member, thereby realizing the rapid connection between the air outlet and the fan coil unit; conversely, the air outlet and the fan coil unit can be quickly disassembled; the technical solution of the present application can realize the rapid installation and disassembly of the fan coil unit and the air outlet, which is convenient for practical use.

[0013] Optionally, the rotating handle includes a C-shaped pressing portion, and the C-shaped pressing portion is used to contact the inner side of the air inlet and outlet of the fan coil unit.

[0014] By adopting the above technical solution, when the handle is turned, the C-shaped pressing portion can enter the inner side of the air inlet and outlet of the fan coil unit and contact it, and tightly press the air inlet and outlet ends of the fan coil unit against the blocking member.

[0015] Optionally, the rotating handle is made of cold-drawn round steel or spring steel.

[0016] By adopting the above technical solution, the rotating handle made of cold-drawn round steel or spring steel is easy to undergo a certain elastic deformation, pressing the inlet and outlet ends of the fan coil unit tightly against the blocking member, thereby achieving the purpose of fixing the air outlet through the blocking member and the rotating handle.

[0017] Optionally, it also includes a fixed plate arranged on the inner side of the air outlet, and the rotating handle is rotatably arranged on the fixed plate.

[0018] By adopting the above technical solution, the rotating handle is installed on the fixed plate, and the rotating setting of the rotating handle inside the air outlet is realized through the connection between the fixed plate and the air outlet.

[0019] Optionally, the fixing plate is a galvanized steel plate.

[0020] Optionally, the blocking member is a blocking angle.

[0021] Optionally, the retaining angle is fixed to the outside of the air duct by rivets.

[0022] By adopting the above technical solution, the retaining angle is a separate structure. In actual use, the position of the retaining angle on the air outlet can be set according to the air outlet structure of the fan coil unit, and the retaining angle can be fixed to the air outlet by rivets.

[0023] Compared with the prior art, this application has the following beneficial effects:

[0024] The present application can realize the quick installation and disassembly of the fan coil unit and the air outlet by turning the handle, thus solving the problem of inconvenient installation close to the ceiling, avoiding the generation of noise in the later stage, and facilitating practical use.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] The fan coil unit used in the present application is a prior art structure, and the fan coil unit has an air inlet and an air outlet connected to an air outlet or an air duct.

[0030] like Figure 1 As shown, the present application provides a quick connection structure between a fan coil unit and an air outlet, which includes a blocking member and a rotating handle 2, which are respectively installed on the outside and inside of the air outlet 3, and the rotating handle 2 is restricted inside the air outlet 3 and cannot move, and can only rotate at a certain angle.

[0031] One end of the air vent 3 is inserted into the air inlet and outlet of the fan coil unit, which is regarded as the installation end. After the air vent 3 is inserted into the air inlet and outlet of the fan coil unit, the air inlet and outlet ends of the fan coil unit are in contact with the blocking member, and then the rotating handle 2 located in the air vent 3 is turned, and the upper end of the rotating handle 2 is screwed into the inside of the fan coil unit and contacts it. The rotating handle 2 makes the air inlet and outlet of the fan coil unit tightly pressed against the blocking member, so that the air vent 3 and the fan coil unit can be quickly installed. Similarly, the air vent 3 and the fan coil unit can be quickly disassembled by operating the rotating handle 2.

[0032] In summary, it can be seen that the technical solution in this embodiment can realize the rapid installation and disassembly of the fan coil unit and the air outlet 3, which is convenient for practical use.

[0033] In this embodiment, in order to achieve stability in the connection between the air outlet 3 and the fan coil unit, at least one rotating handle 2 is installed on each side of the air outlet, and the rotating handle 2 is a Z-shaped structure.

[0034] In a possible embodiment, the rotating handle 2 includes a C-shaped pressing portion, and the C-shaped pressing portion is used to contact the inner side of the air inlet and outlet of the fan coil unit. When the rotating handle 2 is rotated, the C-shaped pressing portion can enter the inner side of the air inlet and outlet of the fan coil unit and contact it, and the end of the air inlet and outlet of the fan coil unit is tightly pressed against the blocking member.

[0035] In addition, the rotating handle 2 is made of cold-drawn round steel or spring steel. The rotating handle 2 made of cold-drawn round steel or spring steel is easy to undergo a certain elastic deformation, so that the air inlet and outlet ends of the fan coil unit are tightly pressed against the blocking member.

[0036] In order to realize the installation of the rotating handle 2 in the air outlet 3 , a fixing plate 1 is fixedly installed on the inner side of the air outlet 3 , and the rotating handle 2 is rotatably installed on the fixing plate 1 .

[0037] In order to avoid damage to the fixing plate 1 , the fixing plate 1 is made of a galvanized steel plate.

[0038] In a possible embodiment, the blocking member and the air outlet 3 are an integrated structure, and the blocking member is a structure that facilitates positioning of the air outlet 3 to determine the depth of the air outlet 3 entering the air inlet and outlet of the fan coil unit.

[0039] In another possible embodiment, the blocking member and the air outlet 3 are separate structures, and the blocking angle 4 is a separate structure. In actual use, the position of the blocking angle 4 on the air outlet 3 can be set according to the inlet and outlet structure of the fan coil unit, thereby improving the adaptability of the present application.

[0040] In order to facilitate the connection between the blocking member and the air outlet 3, the blocking member is a blocking angle 4, the cross section of which is an L-shaped structure, which includes a blocking surface and a veneer, the blocking surface is used to fit with the end of the air inlet and outlet of the fan coil, and the veneer is used to fit with the side of the air outlet 3, and the blocking angle 4 is fixed on the outside of the air outlet 3. Of course, the blocking angle 4 can also be set to other suitable structures.

[0041] In the above, the retaining angle 4 can be made of aluminum alloy, and the air outlet 3 is also made of aluminum alloy. The retaining angle 4 is fixed to the air outlet 3 by rivets 5.

[0042] In addition, the materials of the retaining angle 4 and the air outlet 3 can be the same or different, and the two can be fixed by bolts or the like.

[0043] The use of this application is:

[0044] First, measure the size of the fan coil unit's air inlet and outlet, and select the appropriate air outlet according to the size of the fan coil unit's air inlet and outlet 3;

[0045] Next, fix the retaining angle 4 at a suitable position outside the air outlet 3 by rivet 5;

[0046] Finally, insert the air outlet 3 into the fan coil unit so that the retaining angle 4 on the air outlet 3 contacts the air inlet and outlet ends of the fan coil unit. Turn the rotating handle 2 inside the air outlet 3. The C-shaped pressing part on the rotating handle 2 presses the air inlet and outlet of the fan coil unit tightly against the retaining angle 4, thereby realizing the rapid installation of the air outlet 3 and the fan coil unit.

[0047] Similarly, the air outlet 3 and the fan coil unit can be quickly disassembled.

[0048] In summary, the connection structure of the present application greatly improves the connection speed between the fan coil unit and the air outlet while ensuring the connection quality, reduces the interference of other types of work during the rush stage, and is convenient for practical use. At the same time, it is convenient for disassembly for later maintenance, and it solves the potential risk of resonance noise caused by the inconvenient installation of the fan coil unit on the ceiling, which is convenient for practical use.
