Detailed implementation manners

[0026] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] To solve the technical problems in the prior art, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0028] As Figures 1 to 2 shown, an embodiment of the present utility model discloses an air inlet assembly, which includes an air inlet grille 100 and a filter structure 101. The filter structure 101 is fixedly installed on one side of the air inlet grille 100. Both sides of the air inlet grille 100 are penetrated to form an air inlet channel. A porous structure 103 is provided in the air inlet channel. A smoke alarm 102 is fixedly installed in the porous structure 103, and the smoke alarm 102 is connected to a control module.

[0029] In this embodiment, the air inlet assembly is installed on the air inlet panel assembly 200. Specifically, the filter structure 101 is fixedly installed on one side / air outlet side of the air inlet grille 100. The air return side and the air outlet side of the air inlet grille 100 communicate with each other to form an air inlet channel. A porous structure 103 is arranged in the air inlet channel. This through-hole structure can be more conducive to the air return of the air inlet grille 100. Then, the smoke alarm 102 is installed in the porous structure 103, and the smoke alarm 102 is connected to the control module. In this way, the air inlet assembly has a smoke alarm function.

[0030] Taking advantage of the characteristics of the installation structure of the ceiling unit, specifically, the ceiling unit panel is installed on the ceiling, and the smoke alarm 102 on the air intake grille 100 is synchronously installed following the ceiling unit panel, which is convenient for installation. At the same time, the smoke alarm 102 is installed on the return air side of the air intake grille 100, without affecting the original air supply service. When the ceiling unit is operating, the air-conditioning return air passes through the smoke alarm 102, the porous structure 103, the air intake grille 100 in sequence and then passes through the filtering structure 101 for filtration.

[0031] The smoke alarm 102 remains in the activated state, continuously monitoring and collecting the smoke value in real time. If the smoke value collected by the smoke alarm 102 is greater than the set smoke value, the smoke alarm 102 will be activated to give an alarm. When the ceiling unit air conditioner is operating, since the smoke alarm 102 is located on the return air side of the ceiling unit panel, that is, the smoke alarm 102 is installed on the return air side of the air intake grille 100, at this time, the smoke alarm 102 collects the flowing air and detects the dynamic smoke value in the air in real time. Compared with the state when the ceiling unit air conditioner is not operating, the smoke value in the air collected by the smoke alarm 102 is updated faster when the ceiling unit air conditioner is operating. If it detects that the smoke value in the air increases, the smoke alarm 102 can respond faster.

[0032] Generally, the smoke alarm 102 can be installed in the middle of the porous structure 103, that is, the smoke alarm 102 is installed at the exact center position of the air intake grille 100. The air-conditioning return air is concentratedly sucked into the middle of the air intake grille 100. In this way, the smoke alarm 102 can collect the smoke value in the air-conditioning return air more accurately and sensitively and respond quickly according to the collected smoke value.

[0033] In this embodiment, the smoke alarm 102 is installed at the air return opening, which is more conducive to detecting smoke. At the same time, the smoke alarm 102 can be inspected and maintained while checking the air conditioner. At the same time, the filtering structure 101 is set to adsorb dust and the like in the air and purify bacteria. The detection end of the smoke alarm 102 is set far away from the filtering structure 101 to prevent excessive dust from affecting the sensitivity of the smoke alarm 102.

[0034] Moreover, the porous structure 103 in this embodiment does not block the air-conditioning return air from flowing from the return air side of the air intake grille 100 to the air outlet side, maintaining the original air supply service.

[0035] Furthermore, the porous structure 103 can be designed as a porous structure 103 plate, and its shape is the same as the shape of the air intake channel of the air intake grille 100. For example, the cross-section of the air intake channel of the air intake grille 100 is circular or square. Correspondingly, the porous structure 103 plate is also circular or square. The porous structure 103 plays a role in fixedly installing the smoke alarm 102, and at the same time, the porous structure 103 is more conducive to the air-conditioning return air.

[0036] In some embodiments, the porous structure 103 is fixedly connected to the air inlet grille 100, and detachable methods such as screw connection, threaded connection, snap connection, etc. can be adopted.

[0037] Furthermore, a limiting ring 1031 is formed at the outer peripheral edge of the porous structure 103, and the top of the limiting ring 1031 abuts against the edge of the air return opening of the air inlet grille 100. Specifically, the inner diameter of the limiting ring 1031 is larger than the inner diameter of the air return opening of the air inlet grille 100, and the limiting ring 1031 abuts on one side of the air inlet grille 100, on the side where the porous structure 103 is close to the filter structure 101. Further still, the limiting ring 1031 is fixedly connected to the air inlet grille 100 by detachable methods such as screw connection, threaded connection, snap connection, etc., and the porous structure 103 is fixedly installed on the air inlet grille 100 through the limiting ring 1031.

[0038] In some embodiments, the smoke alarm 102 is fixed to the porous structure 103 by means such as gluing, screws, threaded connection, etc. For example, fixing pieces are provided on the porous structure 103, and the smoke alarm 102 is fixedly connected to the fixing pieces by screws. Also for example, the smoke alarm 102 is adhered to the porous structure 103 with glue. Correspondingly, positioning holes are provided in the middle of the porous structure 103, and the smoke alarm 102 is inserted into the positioning holes.

[0039] In some embodiments, a positioning ring 1010 is formed at the outer peripheral edge of the filter structure 101, and the positioning ring 1010 abuts against the top of the limiting ring 1031. Specifically, the bottom of the positioning ring 1010 is fitted with the limiting ring 1031, that is, a positioning recess is provided at the bottom of the positioning ring 1010, and the radian of the positioning recess matches the outer peripheral radian of the limiting ring 1031. In this way, the outer periphery of the limiting ring 1031 is inserted into the positioning recess, or it can be said that the limiting ring 1031 is snap-connected with the positioning recess. Similarly, the positioning ring 1010 is fixedly connected to the limiting ring 1031 by detachable methods such as screw connection, threaded connection, snap connection, etc.

[0040] In addition, the shapes of the limiting ring 1031 and the positioning ring 1010 are the same as the shape of the air return opening / air inlet channel of the air inlet grille 100. For example, the shapes of the limiting ring 1031 and the positioning ring 1010 are circular.

[0041] Furthermore, the filter structure 101 includes multiple layers of filter meshes, and the multiple layers of filter meshes can be composed of multiple layers of activated carbon filter meshes, multiple layers of HEPA filter meshes, or a combination of multiple layers of activated carbon filter meshes and multiple layers of HEPA filter meshes.

[0042] In some embodiments, a support frame 1020 is provided on one side of the filtering structure 101. The support frame 1020 is used to limit and fix the filter net. A plurality of limiting recesses 1011 are provided along the circumferential direction on the inner side of the positioning ring 1010 to fix the filter net on the support frame 1020, and the outer periphery of the support frame 1020 is embedded in the limiting recesses 1011.

[0043] Further, a toothed structure 1023 is provided on the side of the support frame 1020 close to the porous structure 103. The toothed structure 1023 can be arranged facing the porous structure 103. In this way, the filter net is arranged on the side close to the porous structure 103, and the toothed structure 1023 is clamped with the pores of the filter net to realize the limit and fixation of the filter net.

[0044] Furthermore, the support frame 1020 is provided with a fixing plate 1022 and a limiting rod 1021. The toothed structure 1023 is arranged on the fixing plate 1022. The limiting plate is fitted and connected with the limiting recess 1011, and the fixing plate 1022 abuts against the positioning ring 1010. Preferably, the fixing plate 1022 and the limiting rod 1021 are cross-distributed.

[0045] During assembly, the filter net, the support frame 1020 and the positioning ring 1010 are assembled into the filtering structure 101. The smoke alarm 102 is installed in the porous structure 103 of the air inlet grille 100. The porous structure 103 is installed on the air inlet grille 100 through the limiting ring 1031. Then, the filtering structure 101 and the air inlet grille 100 are assembled into the air inlet assembly. The air inlet assembly is assembled with the air inlet panel assembly 200, and the air inlet panel assembly 200 is assembled with the air outlet panel assembly 300.

[0046] As Figures 1 to 5 shown, based on the same inventive concept, the embodiment of the present utility model further provides a ceiling machine panel, which includes the above-mentioned air inlet assembly, and further includes an air outlet assembly. The air outlet assembly is provided with an air outlet panel assembly 300 and a fixed panel assembly 400. The air inlet assembly, the air outlet panel assembly 300 and the fixed panel assembly 400 are arranged in sequence. The air outlet panel assembly 300 is clamped and connected with the fixed panel assembly 400, and an antenna assembly 6 is arranged around the shell of the fixed panel assembly 400.

[0047] The ceiling machine panel is composed of an air inlet assembly, an air inlet panel assembly 200, an air outlet panel assembly 300 and a fixed panel assembly 400. The air inlet assembly, the air inlet panel assembly 200, the air outlet panel assembly 300 and the fixed panel assembly 400 are arranged in sequence from bottom to top.

[0048] The air outlet panel assembly 300 is provided with a positioning port 301, and the fixed panel assembly 400 is provided with a limiting boss 401. The limiting boss 401 is fitted into the positioning port 301, and the limiting boss 401 of the fixed panel assembly 400 is fixed on the inner side of the air outlet panel assembly 300, thus realizing the snap connection between the air outlet panel assembly 300 and the fixed panel assembly 400. The limiting boss 401 is provided with a limiting port, and the limiting port is communicated with the positioning port 301.

[0049] A smoke alarm 102 is installed on the air inlet grille 100 of the ceiling unit panel. The air conditioner electrical box 5 is installed on the fixed panel assembly 400. The interior of the electrical box 5 integrates WIFI function control components. The antenna assembly 6 is connected to the WIFI function control components. At the same time, the electrical box 5 has the functions of controlling the relevant functions of the ceiling unit air conditioner, integrating multiple functions into one. In this way, the ceiling unit panel has wireless WIFI and smoke alarm functions, can realize remote control of the unit operation and provide wireless functions to the outside, and can also provide smoke alarm functions.

[0050] In some embodiments, the housing of the air outlet panel assembly 300 is provided with a plurality of wire passing buckles 302 and wire passing holes 303. The openings of the wire passing buckles 302 are arranged on the side facing away from the air inlet assembly, and the wire passing buckles 302 are arranged around the inner side of the air outlet panel assembly 300.

[0051] The wire passing buckles 302 play a role in limiting and fixing the wire routing to prevent the wires from falling off. The antenna, the electrical box 5 and their connecting wires provide WIFI functions. The connecting wires of the antenna and the electrical box 5 pass through the wire passing holes 303. After the fixed panel assembly 400 is fixedly installed with the ceiling, the wires are hidden inside the fixed panel assembly 400, having functions such as dust prevention, waterproofing and aesthetics.

[0052] Among them, the wire passing holes 303 are designed as semicircular hole positions, and the aperture size is adjusted according to the actual situation of the wire diameter. They are designed at the four corners to facilitate the wire routing of the connecting wires of the 4 antennas. The wire passing buckles 302 are designed with inlet and outlet ports for easy wire routing operation, and are also designed with an inverted buckle structure to ensure that the wire routing does not come out.

[0053] The electrical box 5 is designed at the air return port position. Specifically, the electrical box 5 is located in the air flow outlet direction of the air return port of the air inlet grille 100.
