DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] The present invention provides an industrial ceiling air conditioner, such as Figures 1 to 8As shown, it includes a shell 1, and two air outlet pipes 2 are installed inside the shell 1. The opening at the front end of the air outlet pipe 2 corresponds to the notch in the front side of the shell 1. The rear end of the air outlet pipe 2 is connected to the output end of the evaporator 3 by a connecting assembly, and the rear side of the evaporator 3 is connected to the fan output end by a conduit 4. The top and bottom of the shell 1 are both snapped with a sealing plate 24, and the four corners of the sealing plate 24 are connected to the shell 1 by bolts. The sealing plate 24 at the bottom of the shell 1 is installed on the top of the bracket 25, and the bracket 25 is correspondingly hoisted on the wall. The air outlet pipe 2 is installed inside the shell 1, and the front end of the air outlet pipe 2 corresponds to the notch in the front side of the shell 1. At this time, the through pipe 5 of the connecting assembly is sleeved on the rear end of the air outlet pipe 2, and the connecting assembly is connected to the output end of the evaporator 3. Install two sealing plates 24 on the top and bottom of the shell 1 respectively. Use bolts to fix the sealing plates 24 on the shell 1. Place the shell 1 with the sealing plates 24 on top of the bracket 25. The bracket 25 is hoisted on the wall to complete the hoisting of the shell 1.

[0029] Start the fan, and the air discharged from the fan output end enters the evaporator 3 through the duct 4. The evaporator 3 cools the air. The cooled air enters the air outlet duct 2 through the connecting component, and finally the air outlet duct 2 discharges the air, which facilitates cooling the room.

[0030] The connecting assembly includes: a through pipe 5, an insertion rod 6, a filter plate 7 and a bellows 8; a tail pipe 201 is provided at the rear end of the air outlet pipe 2, and the front end of the through pipe 5 is correspondingly sleeved on the rear end of the tail pipe 201. The inner end of the insertion rod 6 horizontally passes through the front side of the through pipe 5, and the outer side surface of the circumference of the tail pipe 201 is provided with a first slot 202 corresponding to the insertion rod 6. The locking component enables the inner end of the insertion rod 6 to be correspondingly inserted into the first slot 202. A filter plate 7 is provided at the rear end of the through pipe 5, and a convex edge is provided on the front side of the filter plate 7. A bellows 8 is provided between the filter plate 7 and the evaporator 3. The rear end of the bellows 8 is connected to the output end of the evaporator 3. The elastic component enables the front end of the bellows 8 to squeeze the rear side of the filter plate 7 and push the convex edge of the filter plate 7 to be clamped on the rear end of the through pipe 5. After the air outlet duct 2 is installed inside the shell 1 using the buffer component, the through pipe 5 of the connecting assembly is sleeved on the surface of the tail pipe 201, and the through pipe 5 is pushed forward on the surface of the tail pipe 201 until the inner end of the insertion rod 6 corresponds to the first slot 202. The locking component makes the inner end of the insertion rod 6 correspondingly inserted into the inside of the first slot 202, and the locking component is used to fix the through pipe 5 on the surface of the tail pipe 201. At this time, the elastic component pushes the bellows 8 to stretch, and the front end of the bellows 8 pushes the filter plate 7 forward until the convex edge of the front side of the filter plate 7 is clamped on the rear end of the through pipe 5.

[0031] The air cooled by the evaporator 3 enters the interior of the through-tube 5 through the bellows 8 and the filter plate 7 , and the cooled air is filtered by the filter plate 7 to prevent dust and impurities in the air from entering the room through the air outlet pipe 2 .

[0032] exist Figure 3 、 Figures 5 to 8 In the embodiment, the locking components include: side 9, pressure plate 10, insertion strip 11, protruding rod 12, and side frame 13; side 9 is fixed on both sides of the front side of the through tube 5, the inner end of the insertion rod 6 passes through the side 9 and the through tube 5, and a pressure plate 10 is provided on the rear side of the side 9. The top and bottom of the front side of the pressure plate 10 are fixed with insertion strips 11, and the rear side of the side 9 is provided with a second slot 901 corresponding to the insertion strip 11. The front side of the pressure plate 10 is connected to the rear side of the side 9 by a first elastic member 14. The first elastic member 14 is set as a spring sheet. The outer side of the pressure plate 10 is connected with the protruding rod 12, and the outer end of the insertion rod 6 is connected to two side frames 13. The inner end of the side frame 13 is provided with a card hole 131. The elastic force of the first elastic member 14 passes through the pressure plate 10 so that the front end of the protruding rod 12 is inserted into the card hole 131. The inner side of the side frame 13 is set as a round tube, and the clamping hole 131 is located inside the round tube on the rear side of the insertion rod 6. Two opposite arc-shaped plates 15 are fixed on the outer side of the side edge 9. The two side frames 13 correspond to the two arc-shaped plates 15 one by one. A sliding groove 151 is set at the center of the arc-shaped plate 15. When the insertion rod 6 moves, the insertion rod 6 causes the round tube of the side frame 13 to move inside the sliding groove 151. Pull the pressure plate 10 backward, and while the backward pressure plate 10 pulls the first elastic member 14, the pressure plate 10 pulls the protruding rod 12 away from the insertion rod 6. The moving pressure plate 10 pulls the insertion strip 11 backward inside the second slot 901 until the front end of the protruding rod 12 is pulled out from the inside of the card hole 131, and the insertion rod 6 is pulled outward. The moving insertion rod 6 uses the round tube of the side frame 13 to move inside the slide groove 151 of the arc plate 15 until the round tube is at the outer end of the slide groove 151, and the front end of the through pipe 5 is sleeved on the rear end of the tail pipe 201.

[0033] The through tube 5 is pushed forward on the surface of the tail tube 201, and the moving through tube 5 drives the insertion rod 6 to continue to move forward until the inner end of the insertion rod 6 corresponds to the first slot 202. The through tube 5 stops moving and pushes the insertion rod 6 to move inward. The inward-moving insertion rod 6 causes the round tube to move inside the slide groove 151, and the inner end of the inward-moving insertion rod 6 is gradually inserted into the first slot 202 until the locking hole 131 of the side frame 13 corresponds to the protruding rod 12. The tension applied to the pressure plate 10 is released, and the elastic force of the first elastic member 14 causes the pressure plate 10 to move forward. The forward-moving pressure plate 10 causes the insertion strip 11 to move inside the second slot 901, and the pressure plate 10 pushes the protruding rod 12 to move until the front end of the protruding rod 12 is inserted into the locking hole 131.

[0034] The elastic force of the first elastic member 14 is used to lock the protruding rod 12 to the side frame 13, so that the inner end of the insertion rod 6 can be inserted into the first slot 202 to complete the locking of the through pipe 5 and the tail pipe 201, thereby ensuring the continuity of air circulation inside the connecting assembly and avoiding the separation of the through pipe 5 and the tail pipe 201 due to a simple collision.

[0035] Specifically, when the through pipe 5 is gradually sleeved on the surface of the tail pipe 201 and pushes the insertion rod 6 inward, the inner end of the inward-moving insertion rod 6 gradually approaches the tail pipe 201 until the inner end of the insertion rod 6 is inserted into the first slot 202, thereby preventing the inner end of the insertion rod 6 from sliding on the surface of the tail pipe 201.

[0036] The inner end of the insertion rod 6 is inserted into the first slot 202 by manually pushing. The depth of the first slot 202 of different tail pipes 201 is different. Since the through pipe 5 is sleeved on the surface of the tail pipe 201 for a long time, the first elastic member 14 will be damaged. At this time, the insertion strip 11 is pulled out from the second slot 901. At this time, the first elastic member 14 is separated from the side 9, and a new insertion strip 11 is inserted into the second slot 901. The front end of the new first elastic member 14 is connected to the side 9 by gluing. At this time, the protruding rod 12 can be inserted into the card hole 131. By replacing the pressure plate 10, the protruding rod 12 can be adapted to different tail pipes 201.

[0037] exist Figures 2 to 5 In the embodiment, the through-tube 5 is fixed with side strips 16 on both sides of the outer circumference, and the rear side of the side strips 16 is connected to the front side of the evaporator 3 via connecting rods 17. Hooks 701 are fixed to both sides of the outer circumference of the filter plate 7, and the two hooks 701 correspond one-to-one with the two connecting rods 17. The bayonet holes at the bottom of the hooks 701 correspondingly snap onto the surfaces of the connecting rods 17. When the through-tube 5 is pushed forward inside the housing 1, the advancing through-tube 5 uses the connecting rods 17 on the rear side of the side strips 16 to pull the evaporator 3 forward. The advancing evaporator 3 gradually pulls the conduit 4 into the interior of the housing 1 until the locking component secures the through-tube 5 to the surface of the tail pipe 201, at which point the evaporator 3 stops moving.

[0038] The bellows 8 is pushed to move backward. The backward bellows 8 squeezes the elastic component during the contraction process, and the front end of the bellows 8 gradually moves away from the rear end of the through pipe 5, placing the filter plate 7 between the bellows 8 and the through pipe 5. At this time, the hook 701 of the filter plate 7 is hooked on the surface of the connecting rod 17 using the bayonet, and the tension applied to the bellows 8 is released. The elastic component pushes the bellows 8 to stretch. When the stretched bellows 8 contacts the rear side of the filter plate 7, the bellows 8 pushes the filter plate 7 forward until the convex edge of the front side of the filter plate 7 is clamped on the rear end of the through pipe 5. At this time, the front end of the bellows 8 is connected with the through pipe 5 through the filter plate 7.

[0039] After the bellows 8 is connected to the through-tube 5 through the filter plate 7 by utilizing the elastic force of the elastic component, the filter plate 7 continues to filter the wind passing through the bellows 8. After the entire air conditioner has been used for a period of time, the sealing plate 24 on the top of the outer shell 1 is opened, and the bellows 8 is pulled backward. The contracted bellows 8 gradually moves away from the filter plate 7, and the filter plate 7 is removed from the connecting rod 17. A new filter plate 7 is placed between the bellows 8 and the through-tube 5. At this time, the elastic component causes the stretched bellows 8 to squeeze the new filter plate 7, which facilitates the quick replacement of the filter plate 7 without stopping the fan, thereby ensuring the continuous operation of the air conditioner.

[0040] exist Figure 3 、 Figure 4 and Figure 5 In the figure, the elastic component includes: a slide plate 18 and a second elastic member 19, and the second elastic member 19 is configured as a spring sheet; two opposing slide plates 18 are fixed to the front side of the bellows 8, and the two slide plates 18 correspond one to one with the two connecting rods 17. The outer ends of the slide plates 18 are sleeved on the surfaces of the connecting rods 17, and the rear side of the slide plate 18 is connected to the front side of the evaporator 3 by means of the second elastic member 19. The elastic force of the second elastic member 19 pushes the bellows 8 to stretch through the slide plate 18. When the bellows 8 is pulled to contract, the slide plate 18 on the front side of the bellows 8 moves backward on the surface of the connecting rod 17. The backward slide plate 18 cooperates with the evaporator 3 to squeeze the second elastic member 19 until the bellows 8 is completely separated from the filter plate 7. Then, a new filter plate 7 is replaced. At this time, the new filter plate 7 hooks the hook 701 on the surface of the connecting rod 17, and the tension applied to the bellows 8 is released. The elastic force of the second elastic member 19 pushes the bellows 8 to stretch through the slide plate 18. The stretched bellows 8 pushes the filter plate 7 forward, and the filter plate 7 slides on the surface of the connecting rod 17 using the hook 701 until the convex edge of the front side of the filter plate 7 is clamped on the rear end of the through pipe 5. The elastic force of the second elastic member 19 is used to ensure that the bellows 8 and the through pipe 5 are connected.

[0041] Specifically, in the process of contracting the bellows 8 by pulling, the pressure plate 10 is pushed forward, and the forward-moving pressure plate 10 squeezes the first elastic member 14. The elastic force of the first elastic member 14 is used to offset the pushing force of the second elastic member 19 on the evaporator 3, preventing the elastic force of the second elastic member 19 from passing through the connecting rod 17 and the through pipe 5 to cause the inner end of the insertion rod 6 to squeeze the first slot 202, thereby avoiding the horizontal damage of the first slot 202 due to long-term replacement of the filter plate 7, and ensuring the stability of the connection between the through pipe 5 and the tail pipe 201.

[0042] exist Figure 2 and Figure 3In the embodiment, the air outlet duct 2 is installed inside the housing 1 using a buffer component, which includes a convex plate 20, a screw 21, a third elastic member 22, and a nut 23. The convex plate 20 is fixed to the top and bottom of the rear end of the air outlet duct 2. A screw 21 is fixed to the front side of the housing 1, passing through the convex plate 20. The third elastic member 22 is sleeved on the surface of the screw 21. The third elastic member 22 is configured as a spring. The front end of the third elastic member 22 is connected to the front side of the housing 1. The rear end of the third elastic member 22 is in contact with the front side of the convex plate 20. The nut 23 is screwed onto the rear end of the screw 21. The elastic force of the third elastic member 22 causes the rear side of the convex plate 20 to be in contact with the front side of the nut 23. The rotating nut 23 pushes the convex plate 20 forward, and the forward moving convex plate 20 pushes the air outlet duct 2 forward, so that the front end of the air outlet duct 2 is correspondingly engaged with the notch in the front side of the housing 1. When the air outlet pipe 2 is aligned with the notch of the outer shell 1, the air outlet pipe 2 is pushed forward. The forward-moving air outlet pipe 2 drives the convex plate 20 to move forward on the surface of the screw 21. The forward-moving convex plate 20 squeezes the third elastic member 22 on the surface of the screw 21 until the front end of the air outlet pipe 2 is clamped inside the notch. Then, the nut 23 is screwed onto the rear end of the screw 21. The nut 23 is used to limit the convex plate 20 to complete the installation of the air outlet pipe 2.

[0043] When the air cooled by the evaporator 3 passes through the filter plate 7 and enters the interior of the through-tube 5, the cooled air passes through the filter plate 7, pushing the through-tube 5 forward because the filter plate 7 itself can block the air flow. The forward-moving through-tube 5 uses the locking component to push the outlet pipe 2 to squeeze the third elastic member 22. The elastic force of the second elastic member 19 pushes the bellows 8 to extend through the slide 18, so that the front end of the bellows 8 is always connected to the through-tube 5 through the filter plate 7, ensuring the continuity of air circulation within the connection assembly. The elastic force of the third elastic member 22 absorbs the impact of the forward movement of the outlet pipe 2, preventing damage to the outlet pipe 2 from colliding with the notch due to excessive wind speed.

[0044] Working principle of the present invention:

[0045] Reference Figures 1 to 8 As shown, when the air outlet pipe 2 is aligned with the notch of the outer shell 1, the air outlet pipe 2 is pushed forward, and the forward-moving air outlet pipe 2 drives the protruding plate 20 to move forward on the surface of the screw 21. The forward-moving protruding plate 20 squeezes the third elastic member 22 on the surface of the screw 21 until the front end of the air outlet pipe 2 is clamped inside the notch. Then, the nut 23 is screwed onto the rear end of the screw 21, and the nut 23 is used to limit the protruding plate 20, thereby completing the installation of the air outlet pipe 2.

[0046] Pull the pressure plate 10 backward, and while the backward pressure plate 10 pulls the first elastic member 14, the pressure plate 10 pulls the protruding rod 12 away from the insertion rod 6. The moving pressure plate 10 pulls the insertion strip 11 backward inside the second slot 901 until the front end of the protruding rod 12 is pulled out from the inside of the card hole 131, and the insertion rod 6 is pulled outward. The moving insertion rod 6 uses the round tube of the side frame 13 to move inside the slide groove 151 of the arc plate 15 until the round tube is at the outer end of the slide groove 151, and the front end of the through pipe 5 is sleeved on the rear end of the tail pipe 201.

[0047] The through tube 5 is pushed forward on the surface of the tail tube 201, and the moving through tube 5 drives the insertion rod 6 to continue to move forward until the inner end of the insertion rod 6 corresponds to the first slot 202. The through tube 5 stops moving and pushes the insertion rod 6 to move inward. The inward-moving insertion rod 6 causes the round tube to move inside the slide groove 151, and the inner end of the inward-moving insertion rod 6 is gradually inserted into the first slot 202 until the locking hole 131 of the side frame 13 corresponds to the protruding rod 12. The tension applied to the pressure plate 10 is released, and the elastic force of the first elastic member 14 causes the pressure plate 10 to move forward. The forward-moving pressure plate 10 causes the insertion strip 11 to move inside the second slot 901, and the pressure plate 10 pushes the protruding rod 12 to move until the front end of the protruding rod 12 is inserted into the locking hole 131.

[0048] The elastic force of the first elastic member 14 is used to lock the protruding rod 12 to the side frame 13, so that the inner end of the insertion rod 6 can be inserted into the first slot 202 to complete the locking of the through pipe 5 and the tail pipe 201, thereby ensuring the continuity of air circulation inside the connecting assembly and avoiding the separation of the through pipe 5 and the tail pipe 201 due to a simple collision.

[0049] The bellows 8 is pushed to move backward. The backward bellows 8 squeezes the elastic component during the contraction process, and the front end of the bellows 8 gradually moves away from the rear end of the through pipe 5, placing the filter plate 7 between the bellows 8 and the through pipe 5. At this time, the hook 701 of the filter plate 7 is hooked on the surface of the connecting rod 17 using the bayonet, and the tension applied to the bellows 8 is released. The elastic component pushes the bellows 8 to stretch. When the stretched bellows 8 contacts the rear side of the filter plate 7, the bellows 8 pushes the filter plate 7 forward until the convex edge of the front side of the filter plate 7 is clamped on the rear end of the through pipe 5. At this time, the front end of the bellows 8 is connected with the through pipe 5 through the filter plate 7.

[0050] When the fan is started, air from the fan output enters the evaporator 3 through the conduit 4. The evaporator 3 cools the air, which then enters the air outlet duct 2 through the connecting assembly. Finally, the air outlet duct 2 exhausts the air, facilitating indoor cooling. The air cooled by the evaporator 3 passes through the bellows 8 and filter plate 7 and enters the through-duct 5. The filter plate 7 filters the cooled air, preventing dust and impurities in the air from entering the room through the air outlet duct 2.

[0051] When the air cooled by the evaporator 3 passes through the filter plate 7 and enters the interior of the through-tube 5, the cooled air passes through the filter plate 7, pushing the through-tube 5 forward because the filter plate 7 itself can block the air flow. The forward-moving through-tube 5 uses the locking component to push the outlet pipe 2 to squeeze the third elastic member 22. The elastic force of the second elastic member 19 pushes the bellows 8 to extend through the slide 18, so that the front end of the bellows 8 is always connected to the through-tube 5 through the filter plate 7, ensuring the continuity of air circulation within the connection assembly. The elastic force of the third elastic member 22 absorbs the impact of the forward movement of the outlet pipe 2, preventing damage to the outlet pipe 2 from colliding with the notch due to excessive wind speed.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
