Description

Technical Field

[0001] The present invention relates to the technical field of air treatment equipment, in particular to a skylight machine. Background Art

[0002] Skylight units, also known as ceiling units or ceiling-mounted or embedded air conditioners, are widely used because they save space and are more beautiful.

[0003] A return air inlet is formed in the middle of the main frame of the skylight unit, and an air outlet duct is formed around the return air inlet. The gas can enter the main frame through the return air inlet and is discharged from the air outlet duct after being heated by the heat exchanger arranged in the main frame. Due to the temperature difference between the gas at the return air inlet and the gas in the air outlet duct, the skylight unit will have condensation problems.

[0004] In the prior art, in order to prevent condensation from occurring in the overhead crane, thermal insulation sponge is pasted on the side wall of the air outlet duct to prevent temperature transfer. However, in actual operation, the length of the thermal insulation sponge is inaccurate due to errors in the production size of the thermal insulation sponge or operational errors by on-site personnel. When the length of the thermal insulation sponge is too long, the thermal insulation sponge will be stacked and the thickness will increase, which will interfere with the movement of the relevant structures of the overhead crane and cause the reliability of the overhead crane to be poor. Summary of the Invention

[0005] In order to solve the technical problem of poor reliability of a roof crane, a roof crane is provided in which a yielding structure is arranged on a main frame to yield the end of a heat-insulating sponge to ensure reliable movement of related structures.

[0010] The main frame includes an outer shell and an inner shell. The inner shell is arranged in the outer shell, and there is a distance between the inner shell and the outer shell. At least part of the distance forms the air outlet duct. The inner shell is formed with the give way structure, and the thermal insulation structure is arranged on the inner shell.

[0011] The number of the air outlet ducts is at least two, and the yield structure is located between two adjacent air outlet ducts.

[0012] The heat-insulating structure includes a heat-insulating strip, which surrounds the inner shell, and both ends of the heat-insulating strip are arranged at the yield structure.

[0013] A chamfered angle structure is provided at a corner of the inner shell, and both ends of the heat preservation strip are stacked on the chamfered angle structure, and the chamfered angle structure constitutes the yield structure.

[0015] The inner shell is provided with a receiving groove, and the two ends of the heat preservation strip are stacked in the receiving groove to form the stacking part, and the receiving groove constitutes the yield structure.

[0016] The relationship between the width b of the receiving groove and the thickness h2 of the insulation strip is: 1.5h2≤b≤2h2.

[0017] The ceiling machine also includes an air outlet assembly, which can be raised and lowered on the main frame.

[0021] The skylight machine provided by the present invention is provided with a yield structure on the main frame, so that the stacked part of the insulation structure will not protrude from the size of the main frame in the prior art, thereby avoiding interference between the insulation structure and related structures and ensuring the reliability of the skylight machine.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figures 1 to 3 The illustrated skylight machine comprises: a main frame 1, on which an air outlet duct 11 is formed; a thermal insulation structure 2, which is arranged on the side wall of the air outlet duct 11; and a relief structure provided on the main frame 1, with the stacking portion 21 of the thermal insulation structure 2 located at the relief structure. The relief structure is provided on the main frame 1 so that the stacking portion 21 of the thermal insulation structure 2 does not exceed the size of the main frame 1 in the prior art, thereby avoiding interference between the thermal insulation structure 2 and related structures and ensuring the reliability of the skylight machine. At the same time, due to the presence of the relief structure, the length of the thermal insulation structure 2 can be increased when cutting or producing the thermal insulation structure 2. The thermal insulation structure 2 can be stacked at the relief structure to achieve end-to-end connection, further ensuring the reliable installation of the thermal insulation structure 2.

[0029] It should be noted that the main frame 1 is the main load-bearing structure of the ceiling machine. When the ceiling machine is installed, the main frame 1 is used to be installed on the ceiling. Other structures can be directly or indirectly installed on the main frame 1 and fixed to the ceiling through the main frame 1. The ceiling machine has an internal unit part installed in the ceiling. The main frame 1 is connected to the internal unit. Other structures include an air outlet assembly. The air outlet assembly is connected to the main frame 1, and the air outlet assembly can form an air outlet with the main frame 1. The internal unit has an internal unit exhaust port. The first end of the air outlet duct 11 of the main frame 1 is connected to the internal unit exhaust port. The air flow path is: return air port - evaporator - internal unit exhaust port - first end of the air outlet duct 11 - second end of the air outlet duct 11 - air outlet blown out.

[0030] Specifically, the main frame 1 includes an outer shell 12 and an inner shell 13. The inner shell 13 is arranged in the outer shell 12, and there is a distance between the inner shell 13 and the outer shell 12. At least part of the distance forms the air outlet duct 11. The inner shell 13 is used to separate the return air port and the air outlet duct 11. Therefore, the insulation structure 2 needs to be arranged on the inner shell 13. At the same time, the inner shell 13 is formed with the giving way structure to achieve the giving way of the insulation structure 2.

[0031] To achieve multi-directional airflow, the overhead unit is equipped with multiple air outlets facing in different directions. There are at least two air outlet ducts 11, with each air outlet duct 11 corresponding to each air outlet. The yield structure is located between two adjacent air outlet ducts 11. The stacked portions of the insulation structures 2 are all located outside the air outlet ducts 11, so that the insulation structures 2 within the air outlet ducts 11 are all single-layer structures, minimizing the impact of the insulation structures 2 on the airflow within the air outlet ducts 11.

[0032] Specifically, the insulation structure 2 includes an insulation strip that wraps around the inner shell 13, with both ends of the insulation strip positioned at the relief structure. When installing the insulation strip, one end of the strip is secured to the relief structure, and then the strip is gradually affixed to the inner shell 13 along its length. Finally, the other end of the strip is secured to the relief structure, completing the installation of the insulation strip.

[0033] Preferably, the insulation strip is a long strip of insulation sponge.

[0034] The inner shell 13 is provided with a chamfered structure 14 at the corner, and the ends of the insulation strip are stacked on the chamfered structure 14, which constitutes the yield structure. The chamfered structure 14 reduces the size of the inner shell 13's corner. When the ends of the insulation strip are stacked on the chamfered structure 14, they do not exceed the size of the inner shell 13 without the chamfered corner. As a result, the stacked structure of the insulation strips does not affect the related structures of the overhead crane, thereby ensuring the reliability of the overhead crane.

[0035] Optionally, the relationship between the maximum thickness h1 of the chamfered structure 14 and the thickness h2 of the insulation strip is: h1 ≥ 2h2. If h1 is too large, the structural strength of the inner shell 13 will be affected; if h1 is too small, the stacked insulation strips cannot be stored, and the reliability of the ceiling machine cannot be guaranteed.

[0036] As another embodiment, the inner shell 13 is provided with a receiving groove 15. The two ends of the insulation strip are stacked in the receiving groove 15 to form the stacking portion 21. The receiving groove 15 constitutes the recessed structure. The receiving groove 15 accommodates the ends of the insulation strip, preventing the stacked strips from resting on the surface of the inner shell 13, thereby ensuring the reliability of the ceiling-mounted machine. The receiving groove 15 also squeezes and secures the ends of the insulation strip, improving its securement.

[0037] Optionally, the relationship between the width b of the receiving groove 15 and the thickness h2 of the insulation strip is: 1.5h2≤b≤2h2. When the width b of the receiving groove 15 is too small, the ends of the insulation strip cannot fit into the receiving groove 15, resulting in the receiving groove 15 being unable to reliably accommodate the ends of the insulation strip. When the width b of the receiving groove 15 is too large, the ends of the insulation strip cannot rub or squeeze against each other, making it easy for the ends of the insulation strip to fall out of the receiving groove 15, and the ends of the insulation strip cannot be reliably accommodated.

[0038] The ceiling machine also includes an air outlet component 3, which can be raised and lowered on the main frame 1. The air outlet component 3 is provided with a first wind shield 4, and the main frame 1 is provided with a second wind shield 5. The first wind shield 4 and the second wind shield 5 cooperate to separate the air outlet duct 11 and the return air outlet on the main frame 1. When the air outlet component 3 is raised and lowered relative to the main frame 1, the first wind shield 4 and the second wind shield 5 can slide relative to each other to ensure the separation effect between the return air outlet and the air outlet duct 11. One side of the second wind shield 5 is in contact with the air inlet of the return air port, and the other side is in contact with the airflow of the air outlet duct 11. Condensation will be generated on the second wind shield 5. At the same time, since the first wind shield 4 needs to slide relative to the second wind shield 5, in order to avoid the insulation structure 2 interfering with the movement of the first wind shield 4, the yield structure is formed on the second wind shield 5, and the insulation structure 2 is arranged on the second wind shield 5. The insulation structure 2 can avoid condensation on the second wind shield 5. At the same time, the yield structure can avoid the insulation structure 2 interfering with the first wind shield 4, thereby ensuring the reliability of the air outlet component 3 and the ceiling machine.

[0039] The air outlet assembly 3 forms an air outlet between the main frame 1 by descending.

[0040] The air outlet assembly 3 includes an air outlet frame, which forms an air outlet between the air outlet frame and the main frame 1, and the air outlet frame rises and falls independently. In other embodiments not shown, the air outlet assembly 3 includes an air outlet frame and a return air panel, which forms an air outlet between the air outlet frame and the main frame 1, and the return air panel is provided with a return air outlet. The air outlet frame and the return air panel are connected and rise and fall together.

[0041] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
