Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to an indoor energy-saving air conditioning unit for a low-carbon building. Background Art

[0002] Low-carbon building indoor energy-saving air-conditioning units refer to air-conditioning system equipment used in low-carbon buildings (buildings with the goal of energy saving, environmental protection, and reducing carbon emissions) that achieve low energy consumption, low pollution, and high energy utilization through optimized design, technological innovation, and efficient operation. At present, there are many energy-saving integrated mobile air conditioners on the market that can be used indoors in low-carbon buildings. They use variable frequency technology to adjust the compressor speed through the inverter to achieve dynamic matching of cooling capacity. When the room temperature is close to the set temperature, the compressor automatically reduces the frequency to reduce energy consumption and maintain a constant temperature.

[0003] The energy-saving indoor air-conditioning unit of a low-carbon building is mainly composed of components such as a body, an exhaust duct and a window baffle. When in use, the body is placed indoors, and the window baffle is installed on the edge of the window frame and pushes the window sash to collide with it. The window baffle is provided with a reserved hole, and the exhaust duct can be quickly inserted into the reserved hole by a buckle. The exhaust duct is used to discharge high-temperature air to the outside, and the exhaust pipe discharges the heat generated by the condenser to the outside, and seals the gap between the exhaust pipe and the window to prevent outdoor hot air from flowing back or mosquitoes from entering the room.

[0004] However, existing low-carbon building indoor energy-saving air-conditioning units still have the following problems: 1. The window baffle is mainly composed of an upper baffle and a lower baffle. One end of the upper baffle is connected to a slide plate and is slidably inserted into the lower baffle plate. A locking piece is provided between the slide plate and the lower baffle plate. When the window baffle plate is adjusted to match the height of the window frame, the upper baffle plate is slid upward to drive the slide plate to slide upward in the lower baffle plate. Finally, the slide plate is locked with a locking piece to fix it after the length is adjusted. Since the width of the slide plate is necessarily smaller than that of the upper baffle plate and the lower baffle plate, even if the window sash is pushed to collide with the window baffle plate, there will still be an obvious gap between the window baffle plate and the window sash. The outdoor hot air will flow back through the gap, increasing the air conditioning load. 2. When the outdoor wind direction is facing the exhaust pipe or when it rains, it will hinder the discharge of high-temperature air in the exhaust pipe, resulting in a decrease in the heat dissipation efficiency of the condenser. In order to maintain the cooling effect, the compressor often needs to be overclocked to compensate for the insufficient heat dissipation, and even offset the energy-saving advantages of the frequency conversion technology; at the same time, rainwater can easily enter the machine through the exhaust pipe, which can easily cause machine operation failure; at the same time, if the indoor energy-saving air-conditioning unit of the low-carbon building is used in streets, communities, etc. and is on the first floor, the hot air discharged from the exhaust pipe can easily cause discomfort to pedestrians outdoors; 3. The exhaust duct is simply fixed to the window baffle by ordinary buckles. When the integrated mobile air conditioner is pushed or dragged indoors to change its position, it is easy to swing the exhaust duct, resulting in loosening or even detachment of the connection between the exhaust duct and the window baffle, thus affecting the use.

[0025] The adjusting mechanism includes a plurality of square sleeves 11, the plurality of square sleeves 11 are respectively fixedly connected to the outer walls of a plurality of rotating columns 12, a rotating ring 14 is slidably inserted through the plurality of square sleeves 11 together, a plurality of pull ropes 29 are fixedly connected to the inner ring surface of the rotating ring 14, one ends of the plurality of pull ropes 29 away from the rotating ring 14 respectively pass through the plurality of square sleeves 11 movably, and one ends of the plurality of pull ropes 29 away from the rotating ring 14 respectively pass through the plurality of rotating columns 12 movably, one ends of the plurality of pull ropes 29 away from the rotating ring 14 are respectively fixedly connected to a plurality of trapezoidal blocks 33, second springs 28 are slidably sleeved on the outer walls of the plurality of pull ropes 29, the plurality of second springs 28 are respectively fixedly connected between the plurality of trapezoidal blocks 33 and a plurality of second cylindrical grooves 27, and a dial block 9 is fixedly connected to the outer ring surface of the rotating ring 14.

[0026] Working principle: First, place the first baffle 4 at the groove corner at the bottom of the window frame. Then, loosen the two knob screws 6 in sequence. At this time, the second baffle 5 can be slid upward. The second baffle 5 will drive the two T-shaped sliding grooves 7 to slide upward outside the two T-shaped sliding blocks 8 on the first baffle 4 respectively until the top end of the second baffle 5 is in close contact with the groove corner at the top of the window frame. Then, tighten the two knob screws 6 in sequence. The ends of the two knob screws 6 will be in close fit with the groove walls of their respective corresponding T-shaped sliding grooves 7, so as to fix the second baffle 5. The combined thickness of the first baffle 4 and the second baffle 5 does not exceed the thickness of the window sash. Then, slide the window sash to be in close fit with the first baffle 4 and the second baffle 5 without obvious gaps, so as to prevent the hot air outside from flowing back through the gaps and increasing the air-conditioning load.

[0027] When the outdoor wind direction is directly facing the exhaust pipe 2 or it is raining, first, through the arc-shaped cover 22, a rain-blocking structure can be formed at the exhaust port of the exhaust pipe 2, so as to prevent rainwater from entering the machine body 1 along the exhaust pipe 2 and avoid the operation failure of the machine body 1. Secondly, by rotating the corresponding rotating column 12 clockwise, the rotating column 12 will drive the adjusting disc 13 to rotate in the inner wall of the first baffle 4. The adjusting disc 13 will drive the toothed ring 10 to rotate. The toothed ring 10 will drive the gear 16 to rotate counterclockwise. The gear 16 will drive the rope winding column 30, the cylinder 31 and the limit disc 19 to rotate together. The connecting rope 18 wound around the rope winding column 30 will be continuously released. When the cylinder 31 rotates, it will drive a plurality of arc-shaped holes 26 to rotate. Three of the arc-shaped holes 26 will respectively squeeze the spherical surfaces of the three spherical pins 25, so that each spherical pin 25 slides away from the cylinder 31 in its respective corresponding first cylindrical groove 23 and squeezes the first spring 24 until the next adjacent three arc-shaped holes 26 rotate to be respectively in contact with the spherical surfaces of the three spherical pins 25, and so on. And when finally stopping the rotation of the adjusting disc 13, under the action of the first spring 24, the three spherical pins 25 will also be in close contact with the corresponding three arc-shaped holes 26 respectively, so as to limit the rotation of the cylinder 31, and thus limit the rotation of the rope winding column 30, the gear 16 and the adjusting disc 13, etc.

[0028] It should be noted that in the above, the adjustment disc 13 rotates clockwise by 90 degrees and then stops rotating. During the rotation of the adjustment disc 13, it will also drive the two arc-shaped rods 32, the two arc-shaped springs 20, the arc-shaped cover 22, the arc-shaped plate 21 and the connecting rope 18 to rotate together. Since the connecting rope 18 will continuously release outside the rope winding post 30 during the rotation, under the action of the two arc-shaped springs 20 (the arc-shaped springs 20 were originally in a compressed state), it will push the arc-shaped plate 21 to rotate outside the two arc-shaped rods 32. And until the adjustment disc 13 rotates clockwise by 90 degrees, the arc-shaped plate 21 will extend a large distance outside the arc-shaped cover 22 and can completely block the exhaust port of the splicing pipe 3. Then the hot air discharged from the exhaust pipe 2 will avoid the wind facing the exhaust pipe 2 outside the window through the arc-shaped cover 22 and the arc-shaped plate 21. And under the guiding of the arc surfaces of the arc-shaped cover 22 and the arc-shaped plate 21, the hot air discharged from the exhaust pipe 2 can be guided to the side, which will not affect the normal discharge of the hot air in the exhaust pipe 2. And the hot air guided to the side can also avoid directly blowing on the pedestrians outside when used on the first floor of the street or community, thus avoiding affecting the energy-saving benefit of the machine body 1 and also avoiding affecting the pedestrians outside.

[0029] For the installation of the exhaust pipe 2, the exhaust pipe 2 is rotatably connected to the splicing pipe 3. Then the splicing pipe 3 can be installed inside the adjustment disc 13. The specific operation is as follows: Hold the splicing pipe 3 and insert it into the hole slot of the adjustment disc 13 (the hole slot of the adjustment disc 13 can be seen from Figure 8 ). During the process, the splicing pipe 3 will push the inclined surfaces of multiple trapezoidal blocks 33 with the collar 15. Each trapezoidal block 33 will move away from the splicing pipe 3 in the corresponding cylindrical slot two 27, and each trapezoidal block 33 will squeeze the spring two 28. Until the collar 15 fits against the side wall of the adjustment disc 13, under the action of the spring two 28, each trapezoidal block 33 will reset and the vertical surface will fit against the side of the collar 15, thus restricting and fixing the collar 15. As shown in Figure 3 、 Figure 6 and Figure 7 . At this time, the installation of the splicing pipe 3 can be completed, and the splicing pipe 3 will just fit against the inner wall of the adjustment disc 13, thus completing the rapid installation of the exhaust pipe 2. And under the restricting action of multiple trapezoidal blocks 33, no matter how the machine body 1 moves and changes its position indoors, the swinging exhaust pipe 2 will not cause the splicing pipe 3 to separate from the adjustment disc 13, and the installation is stable.

[0030] For the disassembly of the exhaust duct 2, hold the dial block 9 and rotate the rotating ring 14 clockwise. The rotating ring 14 will rotate within multiple square sleeves 11. The square sleeves 11 will drive multiple pull ropes 29 to slide outward within the corresponding rotating columns 12, thereby pulling multiple trapezoidal blocks 33 to slide towards their respective corresponding square sleeves 11 within their respective corresponding cylindrical grooves two 27, and will compress the second spring 28 until the vertical surfaces of multiple trapezoidal blocks 33 all leave the collar 15. At this time, the splicing pipe 3 can be quickly pulled out from the adjusting disc 13, thus completing the quick disassembly of the exhaust duct 2.

[0031] It should be noted that the elasticity of the second spring 28 is relatively small, so as to be more convenient for the disassembly and assembly of the exhaust duct 2. The elasticity of the first spring 24 is relatively large, so as to well limit the rotation of the cylinder 31 and the like.

[0032] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
