Description

Technical Field

[0001] The utility model relates to the technical field of combined air-conditioning units, in particular to a combined air-conditioning unit. Background Art

[0002] Traditional combined air-conditioning units are generally composed of a return air fan section, a filter section, a fresh and exhaust air mixing section, a surface cooling water retaining section, an intermediate section, a heating section, a humidification section and a supply air fan section. Among them, the fresh air and the return air are uniformly treated by the surface cooling, and the high-temperature cold water after heat exchange in the surface cooler is transported back to the cold source for treatment through the pipeline network.

[0003] The existing patent (publication number: CN217952517U) discloses a combined air-conditioning unit, including a return air processing end and a fresh air processing end; the return air processing end is used to process the return air and send the processed return air to the fresh air processing end; the fresh air processing end is used to process the fresh air and the processed return air, and send the new and return air into the air-conditioned room after the processing; the return air processing end and the fresh air processing end both include separate surface cooling sections, which are used for processing the return air and the fresh air respectively. By setting the surface cooling sections separately, the fresh air and the return air are processed separately, so that the fresh air can bear the function of removing the residual moisture and part of the residual heat (i.e., latent heat load and part of the sensible heat load) of the air-conditioned room, while the return air only bears the function of removing the residual heat (i.e., sensible heat load) of the air-conditioned room, and there is no need to set up an additional reheating device. The air conditioning supply temperature difference requirement can be met only by adjusting the fresh and return air volumes, thereby avoiding the energy loss caused by consuming reheating heat.

[0004] However, the above technical solution still has certain defects. Bolts are required at the air inlet and outlet of the combined air-conditioning body during the installation process. To fix the air-conditioning body to the ground, fixing holes need to be opened in the ground in advance, and then the bolts are screwed into the fixing holes. During the fixing process, the position of the fixing holes is prone to deviation from the position of the bolts, resulting in the need to re-drill holes during the installation process, resulting in low installation efficiency. For this reason, a combined air-conditioning unit is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] A combined air conditioning unit, such as Figures 1 to 5 As shown, it includes a combined air conditioning unit body 1, and two sets of fixed installation mechanisms 3 are fixedly connected to the bottom end of the combined air conditioning unit body 1;

[0028] The fixed installation mechanism 3 includes a connecting frame 301, and the internal sliding sleeve of the connecting frame 301 is provided with multiple groups of fixed columns 302, the inner wall of the fixed column 302 is rotatably connected with two groups of abutment blocks 304, the abutment blocks 304 extend to the outside of the fixed column 302, and the side walls of each group of abutment blocks 304 are respectively hinged with a group of connecting rods 305, the connecting rods 305 are located inside the fixed column 302, the inner wall of the fixed column 302 is slidably connected with a push rod 306, the top of the push rod 306 extends to the outside of the fixed column 302, the bottom end of the push rod 306 is hinged at the ends of the two groups of connecting rods 305, the bottom end of the push rod 306 is fixedly connected with a second return spring 307, the bottom end of the second return spring 307 is fixedly connected to the bottom end of the inner wall of the fixed column 302, and the outer wall of each group of fixed columns 302 is respectively sleeved with a group of first return springs 303, and the top of the first return spring 303 is fixedly connected to the outer wall of the fixed column 302.

[0029] By pushing the fixing post 302 to slide on the inner wall of the connecting frame 301, the fixing post 302 is aligned with the mounting hole, and then the fixing post 302 is pushed downward to compress the first return spring 303, so that the fixing post 302 extends into the mounting hole. In this process, the abutment block 304 is pushed by the mounting hole and flips over, so that the abutment block 304 pushes the push rod 306 to slide through the connecting rod 305, so that the push rod 306 compresses the second return spring 307, and the end of the abutment block 304 abuts against the inner wall of the mounting hole through the rebound force of the second return spring 307. When the fixing column 302 is pulled up, the friction between the end of the abutment block 304 and the inner wall of the mounting hole will cause the abutment block 304 to flip over, so that the abutment block 304 and the inner wall of the mounting hole are more tightly abutted, so that the fixing column 302 cannot be pulled out of the mounting hole. When the fixing column 302 needs to be pulled out of the mounting hole, the push rod 306 is pushed so that the push rod 306 pushes the abutment block 304 to flip upward through the connecting rod 305, so that the end of the abutment block 304 cannot contact the inner wall of the mounting hole. At this time, the first return spring 303 pushes the fixing column 302 to return to its original position.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3The side wall of the combined air conditioning unit is connected to multiple groups of connecting mechanisms 2, and the connecting mechanism 2 includes a connecting pipe 201. The inner wall of the connecting pipe 201 is slidably connected to two groups of fixed frames 202. The inner wall of each group of fixed frames 202 is respectively fixedly connected to a group of filter cotton 203. The inner wall of the fixed frame 202 is rotatably connected to a rotating shaft 204. The end of the rotating shaft 204 extends to the outside of the fixed frame 202. The rotating shaft 204 is provided with a torsion spring at the connection with the fixed frame 202. One end of the rotating shaft 204 located inside the fixed frame 202 is fixedly sleeved with a gear 205. The inner wall of the fixed frame 202 is slidably connected to two groups of racks 206. The two groups The racks 206 are respectively located on both sides of the gear 205, and the two groups of racks 206 are meshed with the gear 205 at the same time. The inner wall of the fixed frame 202 is slidably connected with two groups of limit pins 207, and each group of limit pins 207 is respectively fixedly connected to the end of a group of gears 205. The ends of the two groups of limit pins 207 extend into the interior of the fixed frame 202, and the fixed frame 202 is provided with limit grooves at the contact positions with the limit pins 207. The outer wall of the connecting tube 201 is rotatably connected with two groups of threaded rods 208, and the outer wall of each group of threaded rods 208 is respectively threadedly connected with a group of clamps 209, and the clamps 209 are slidably connected to the outer wall of the connecting tube 201.

[0031] By inserting the pipe into the connecting pipe 201, and then rotating the two sets of threaded rods 208, the two sets of threaded rods 208 push the two sets of clamping plates 209 closer to each other, so that the two sets of clamping plates 209 clamp the pipe. When the airflow passes through the pipe and enters the interior of the combined air-conditioning unit body 1, the airflow passes through the filter cotton 203, so that the dust in the airflow is filtered out. By rotating the rotating shaft 204, the rotating shaft 204 drives the gear 205 to rotate and twist the torsion spring. The gear 205 pushes the two sets of racks 206 during the rotation process, so that the racks 206 drive the limit pin 207 to slide into the fixed frame 202, so that the limit pin 207 slides out from the inside of the limit groove, and then pulls the rotating shaft 204 causes the fixed frame 202 to slide out of the connecting tube 201, and then the fixed frame 202 with the new filter cotton 203 is pushed into the connecting rod 305, so that the limit pin 207 is pushed by the connecting tube 201, so that the limit pin 207 slides into the connecting tube 201, so that the rack 206 is pushed by the limit pin 207. At this time, the rack 206 drives the rotating shaft 204 to rotate through the gear 205. When the limit pin 207 is aligned with the limit groove, the torsion spring rebounds and drives the rotating shaft 204 to rotate in the opposite direction and reset, so that the gear 205 rotates in the opposite direction. During the reverse rotation of the gear 205, the rack 206 is pushed to reset, so that the limit pin 207 is inserted into the limit groove, and the replacement of the filter cotton 203 is completed.

[0032] When in use, the fixing column 302 is pushed to slide on the inner wall of the connecting frame 301 so that the fixing column 302 and the mounting hole are aligned, and then the fixing column 302 is directly inserted into the mounting hole to fix the fixing hole inside the mounting hole, so that the combined air-conditioning unit body 1 is installed, avoiding the problem of the fixing column 302 and the mounting hole being unable to be aligned, and there is no need for tedious tightening of bolts, thereby improving the installation efficiency. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
