Description

Technical Field

[0002] The indoor unit is an important component of a household air conditioning system. It is mainly responsible for absorbing hot indoor air and cooling it through evaporation. Most indoor units are installed inside the ceiling and then connected to the outdoor unit through connecting pipes. This allows for the regulation of indoor temperature and also enables multi-functional operation of dehumidification and air blowing.

[0003] Currently, most traditional indoor air conditioning units are installed inside the ceiling. After installation, when the indoor fan is damaged, routine maintenance and repairs are performed through the pre-reserved access panel in the ceiling. However, the narrow opening makes maintenance and repair slow, affecting the efficiency of the indoor air conditioning unit. In actual use, the indoor air conditioning unit uses a filter plate to filter the circulating air to prevent dust from polluting the indoor environment. Although the filter plate can filter impurities in the air, without regular maintenance, impurities will clog the filter screen, resulting in poor air output from the indoor air conditioning unit and thus affecting its heating and cooling efficiency. Therefore, this invention proposes an air conditioning humidification and fresh air exchange indoor unit. Summary of the Invention

[0016] 2. In the invention, during the disassembly process, the lower mating block will press against the upper mating block, causing the side spring plate and the side locking block to disengage, so that the installation frame can drive the filter plate to detach from the filter plate bracket, thereby facilitating the replacement of the filter plate, shortening the maintenance time, improving the practicality of the indoor unit, and when the air velocity drops significantly after passing through the filter plate, the blower wheel can still accelerate the filtered fresh air, improving the fresh air exchange efficiency of the indoor unit.

[0017] 3. In the invention, during the operation of the indoor unit, some stubborn dust will exist inside the evaporator. The stubborn dust on the surface of the evaporator can be cleaned by cleaning brush head and cleaning brush plate, thereby extending the service life of the indoor unit and realizing the self-cleaning function of the indoor unit. The cleaning method is driven by a separate drive motor to clean multiple sides of the evaporator, strengthening the linkage between structures and thus reducing structural wear.

[0032] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0034] In existing technologies, indoor fan units are mostly installed inside the ceiling. Because regular inspection and maintenance of the indoor fan are required, a maintenance access port is usually reserved in the ceiling 400. However, the narrowness of the opening can slow down the maintenance process, affecting the efficiency of the indoor fan unit. Furthermore, during actual use, the indoor fan unit exchanges indoor and outdoor air. Most units use a filter plate 308 to filter the circulating air and prevent dust pollution. Although the filter plate 308 can filter impurities in the air, without regular maintenance, impurities will clog the filter screen, resulting in poor airflow from the indoor fan unit and affecting its heating and cooling efficiency. Additionally, some stubborn dust can fall into the fins of the evaporator 106, requiring regular daily maintenance of the evaporator 106, increasing the user's workload and reducing the practicality of the indoor fan unit.

[0035] Therefore, the present invention aims at least to disassemble the indoor unit casing into a lower device casing 101 and an upper device casing 114, and to separate and reassemble the two into a whole by means of a lifting and disassembly assembly 300. At the same time, the linkage mounting frame 319 can assist in the disassembly of the filter plate 308, which not only facilitates the maintenance of the evaporator 106, but also facilitates the daily maintenance of the filter plate 308. During the operation of the indoor fan, the self-cleaning component 200 can perform multi-directional self-cleaning of stubborn dust on the surface of the evaporator 106. It can also work with the blower wheel 324 to accelerate the air speed in the indoor unit, improve the air exchange efficiency and practicality of the indoor unit, reduce the number of maintenance times, and extend the service life of the indoor unit.

[0036] Implementation examples, based on Figure 1-13 ,like Figures 1-3 As shown in the figure, an air conditioning humidifier and fresh air exchange indoor unit provided by an embodiment of the present invention includes an indoor air conditioning component 100. A lifting and disassembly assembly 300 is installed on one side of the indoor air conditioning component 100. A ceiling 400 is installed on the indoor air conditioning component 100 via the lifting and disassembly assembly 300. A limit groove 500 is provided on one side of the ceiling 400 with a preset groove. The lifting and disassembly assembly 300 can replace the filter element during disassembly. The indoor air conditioning component 100 includes an evaporator 106. A self-cleaning component 200 is installed on the upper surface of the indoor air conditioning component 100. The self-cleaning component 200 can clean the evaporator 106.

[0037] like Figures 6-7 As shown, the lifting and disassembly assembly 300 includes a rotating handle 301. A bidirectional screw 305 is fixedly connected to the upper surface of the rotating handle 301. Two threads are provided at both ends of the bidirectional screw 305. The bidirectional screw 305 is connected to a lifting sleeve 306 through the threads on its surface.

[0038] like Figure 11 As shown, the self-cleaning component 200 includes a mounting housing 201, an electric push rod 206 is fixedly connected to one side of the mounting housing 201, and slide rods 203 are fixedly connected to both sides of the inner wall of the mounting housing 201. A first slider 204 is mounted on the slide rod 203, and a fixed seat 205 is fixedly connected between the first sliders 204.

[0039] Specifically, starting the electric push rod 206 can push the fixed base 205 and the first slider 204 to move horizontally on the slide rod 203. Then, by turning the rotary handle 301, the bidirectional screw 305 can be rotated. The bidirectional screw 305 is connected to the lifting sleeve 306 through thread engagement, which can drive the lifting sleeve 306 to move towards the middle of the bidirectional screw 305. The lifting sleeve 306 is connected to the turntable 309 through the transmission plate 307, and the turntable 309 is rotatably mounted on the connecting bracket 312 through the central shaft 311, which can drive the turntable 309 to rotate. The turntable 309 will rotate from an inclined state to a horizontal state, thereby embedding into the limiting groove 500 of the ceiling 400, achieving the installation and fixation of the indoor unit.

[0040] like Figures 4-5 As shown, the air chamber component 100 also includes a lower device housing 101, with an upper device housing 114 positioned above it. The lower device housing 101 and the upper device housing 114 can be assembled as a whole. A return air vent 109 is provided on one side of the lower surface of the lower device housing 101. A partition 103 is fixedly connected to the middle of the lower device housing 101. A control module 104 is fixedly connected to one side of the partition 103, and a filter plate bracket 107 is fixedly connected to the other side of the partition 103. Ventilation holes 108 are provided on both sides of the filter plate bracket 107. A dual-axis motor 110 is installed on one side of the filter plate bracket 107, and blower wheels 111 are installed at both ends of the dual-axis motor 110. The blower wheels 111 are located above the return air vent 109. One end of the filter plate bracket 107 is fixedly connected to both sides. A side clamping block 112 is attached. A side grille 102 is provided on one side of the lower device housing 101. An evaporator 106 is installed near the side grille 102. An L-shaped mounting plate 113 is fixedly connected to one side of the lower surface of the lower device housing 101. A water inlet 105 is provided on one side of the evaporator 106. An L-shaped mounting plate 113 is fixedly connected to one side of the lower surface of the lower device housing 101. An air outlet grille 115 is provided on the front surface of the upper device housing 114. A fixed top plate 116 is fixedly connected to one side of the upper device housing 114. A disassembly port 117 is provided on the side of the upper device housing 114 near the filter plate bracket 107. An air inlet 118 is provided on the side of the upper device housing 114 near the blower wheel 111. An upper mounting bracket 119 is fixedly connected to one side of the upper surface of the upper device housing 114.

[0041] Specifically, since the indoor unit is composed of two upper housings 114 and a lower housing 101, the upper housing 114 and the lower housing 101 can be separated by the lifting and disassembly assembly 300, which facilitates the inspection and maintenance of the evaporator 106 and filter plate 308 on the surface of the lower housing 101.

[0042] like Figures 1-3 As shown, a lifting bracket 316 is movably connected through the L-shaped mounting plate 113. A limit bracket 315 is fixedly connected to the upper end of the lifting bracket 316. A second slider 314 is installed inside the limit bracket 315. An upper connecting plate 313 is fixedly connected to one side of the second slider 314. A top block 317 is fixedly connected to one side of the lifting bracket 316. The top block 317 movably passes through the upper connecting plate 313. A lower mating block 318 is fixedly connected to the upper end of the top block 317. A transmission plate 307 is rotatably mounted on one side of each lifting sleeve 306. A turntable 309 is rotatably mounted on one end of the inner side of the transmission plate 307. A limit block 310 is fixedly connected to one side of the turntable 309. The upper end of the bidirectional screw 305 is rotatably mounted on the lower surface of the fixed top plate 116. A central shaft 311 is fixedly connected to the center of the turntable 309. A connecting bracket 312 is rotatably mounted on the central shaft 311. The connecting bracket 312 is fixedly connected to one side surface of the fixed top plate 116. A threaded sleeve 304 is engaged with the lower end of the bidirectional screw 305. The threaded sleeve 304 is disposed on the L-shaped mounting plate 113.

[0043] Specifically, when the bidirectional screw 305 rotates, since the bidirectional screw 305 is connected to the L-shaped mounting plate 113 through the threaded sleeve 304, and the L-shaped mounting plate 113 is connected to the lower device housing 101, the lower device housing 101 can be driven to rise and fall along the bidirectional screw 305, thereby separating the upper device housing 114 and the lower device housing 101. This facilitates the inspection and maintenance of the evaporator 106 and filter plate 308 on the surface of the lower device housing 101. At the same time, the upper connecting plate 313 is installed in the limiting bracket 315 through the second slider 314, which can limit the lower device housing 101 and assist the lower device housing 101 in rising and falling.

[0044] like Figure 8As shown, an upper mating block 320 is provided above the lower mating block 318. An installation frame 319 is fixedly connected to the upper surface of the upper mating block 320. Side spring plates 321 are fixedly connected to both sides of the installation frame 319. The side spring plates 321 and the side locking blocks 112 can be locked together. A top bracket 326 is fixedly connected to the upper surfaces of both sides of the installation frame 319. A spring rod 327 is installed in the top bracket 326. A support block 328 is fixedly connected to the output shaft of the spring rod 327. The support block 328 is locked to the slot 303. Two installation blocks 302 are provided in the installation frame 319. A slot 303 is provided on the upper surface of each installation block 302. A filter plate 308 is fixedly connected to one side of each installation block 302. Each filter plate 308 is located in the filter plate bracket 107.

[0045] Specifically, when installing the filter plate 308, the filter plate 308 and the mounting block 302 can be placed inside the mounting frame 319. The spring rod 327 can hold the support block 328 in place within the slot 303 of the mounting block 302, thus fixing the filter plate 308 within the mounting frame 319. Since the two sides of the mounting frame 319 are fixedly connected by side spring plates 321, the mounting frame 319 can be connected to the side locking blocks 112 of the filter plate bracket 107 through the side spring plates 321, completing the installation of the filter plate. However, when disassembling the filter plate 308, since the limiting bracket 315 is installed on the L-shaped mounting plate 113 through the lower lifting bracket 316, when the lower device housing 101 descends to a certain position, since the lower end of the lifting bracket 316 is connected to the lower mating block 318 through the top block 317, the lower mating block 318 can press against the upper mating block 320, thereby disconnecting the side spring plate 321 and the side locking block 112, and also causing the mounting frame 319 to pop out, thus facilitating the replacement of the filter plate 308.

[0046] like Figure 9 As shown, a loading plate 322 is fixedly connected between the mounting frames 319. A drive motor 323 is fixedly connected to one side of the loading plate 322. A blower wheel 324 is fixedly connected to the output shaft of the drive motor 323. There are two blower wheels 324. A gear ring 325 is fixedly connected to the edge of each blower wheel 324. Each gear ring 325 is meshed together. The blower wheel 324 is located between two filter plates 308.

[0047] Specifically, starting the drive motor 323 can drive one of the blower wheels 324 to rotate, and the two blower wheels 324 are connected together by the meshing of the gear ring 325, which can drive the two blower wheels 324 to rotate synchronously. Thus, the blower wheels 324 can also speed up the exchange of filtered fresh air, thereby improving the fresh air exchange efficiency and practicality of the indoor unit.

[0048] like Figures 12-13As shown, the output shaft of the electric push rod 206 is fixedly connected to the fixed base 205. The fixed base 205 is equipped with two parallel first support rods 207. The mounting housing 201 is fixedly connected to the upper surface of the upper device housing 114. A second support rod 208 is rotatably mounted in the middle of one of the first support rods 207. A mounting base 202 is rotatably mounted at one end of the second support rod 208. The mounting base 202 is fixedly connected to one side of the inner wall of the mounting housing 201. A fixed sheet metal 209 is rotatably mounted at the same end of both first support rods 207. A lifting plate 210 is fixedly connected to the lower end of the fixed sheet metal 209. A first sliding groove 211 is provided in the middle of the lifting plate 210. A rotating rod 218 is rotatably mounted in the first sliding groove 211. A movable block is rotatably mounted on the upper end of the rotating rod 218. 219, a drive screw 215 is threadedly connected to one side of the movable block 219, a drive motor 214 is fixedly connected to one end of the drive screw 215, the drive motor 214 is fixedly connected to the upper surface of the lifting plate 210, a second slide groove 213 is provided on one side of the lifting plate 210, a first toothed plate 220 is fixedly connected to the other side of the lifting plate 210, a sliding sheet metal 216 is movably installed in the second slide groove 213, a cleaning brush plate 217 is fixedly connected to one side of the sliding sheet metal 216, a second toothed plate 212 is fixedly connected to one side of the sliding sheet metal 216, a transmission gear 221 is fixedly connected to the lower end of the rotating rod 218, a cleaning brush head 222 is fixedly connected to the lower surface of the transmission gear 221, and the transmission gear 221 is connected to the first toothed plate 220 and the second toothed plate 212 through a snap-tooth engagement;

[0049] Specifically, when the electric push rod 206 pushes the fixed base 205 to move horizontally, the fixed base 205 is rotatably mounted with two first support rods 207. One of the first support rods 207 is rotatably mounted with a second support rod 208 on one side. After being limited by the second support rod 208, the first support rod 207 can be pushed to rotate within the fixed base 205. Then, a fixed sheet metal 209 is rotatably mounted on the same end of the two first support rods 207. The lower end of the fixed sheet metal 209 is fixedly connected to a lifting plate 210, which can drive the lifting plate 210 to descend above the evaporator 106. Then, the drive motor 214 is started to drive the drive screw 215 to rotate. The drive screw 215 will drive the rotating rod 218 to move horizontally within the first slide groove 211. Then, a transmission gear 221 and a cleaning brush head 222 are rotatably mounted on the lower end of the rotating rod 218. The gear 221 is engaged with the first gear plate 220, which drives the transmission gear 221 and the cleaning brush head 222 to rotate and move horizontally.
