Description

Technical Field

[0001] The present invention relates to the technical field of fresh air systems, and in particular to a combined air conditioning unit. Background Art

[0002] Combined air conditioning units are a type of centralized air handling equipment, which are widely used in commercial buildings, industrial plants, hospitals, data centers and other places. Its modular design allows users to flexibly combine functional sections (such as filtration, heating, cooling, humidification, air supply, etc.) according to their needs to meet different temperature and humidity, cleanliness and air volume requirements. With the increasing demand for energy conservation and environmental protection, combined air conditioning units are developing in the direction of high efficiency, low noise and intelligence.

[0003] However, in the process of heating or cooling the airflow, the existing combined air conditioning units will have low heat exchange efficiency due to uneven airflow distribution of the surface cooler / heater, which will lead to low fan / heat exchange efficiency and high energy consumption.

[0004] The patent document with the publication number CN217817129U that has been published includes a combined chassis, and a first air inlet and a second air inlet are installed at one end of the double-layer combined chassis. A filter is provided in the combined chassis near the first air inlet and the second air inlet. The filter is used to connect the air inlet of the hot air group and the air inlet of the cold air group. A filter plate is provided inside the filter to filter the air entering from the two air inlets, so that the hot and cold air generated by the combined air conditioner can be kept clean. A duct is connected to the filter plate, and a nozzle is provided on the duct. Water is supplied through a water pipe, and the filter plate is cleaned by the nozzle. Sewage enters the two sewage pipes through two opened sewage outlets and is discharged outward.

[0005] When the above device is in use, the filter plate is fixed by being installed on the filter housing, and water is sprayed and cleaned by using the conduit on the filter plate. During this process, the conduit only sprays water mist on the filter screen to cover the dust, but the water mist sticks to the filter screen, and there will still be a large amount of dust residue on it, resulting in a low filtering effect.

When the filter mounting frame moves from bottom to top, since the side of the two-way step frame is arc-shaped and the bottom of the arc-shaped hole of the arc-shaped guide hole frame is also arc-shaped, the arc-shaped surface at the bottom of the arc-shaped guide hole frame contacts the arc-shaped surface on the side of the two-way step frame and returns to its original position. With the cooperation of the corresponding adjustment components, the filter mounting frame can swing left and right and vibrate up and down repeatedly, thereby improving the cleaning effect of dust and sewage; 4. When the customer needs to clean, he only needs to pull out the dry filter from one side of the dry dust collection box for cleaning. Compared with the traditional technology, which requires disassembling and cleaning each filter, its installation is relatively simple and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, a combined air conditioning unit proposed by the present invention comprises a positioning frame 1, two air inlet components 2 for conducting airflow are fixedly installed on one side of the positioning frame 1, a heating component 3 for heating airflow is fixedly installed on the upper layer of the positioning frame 1, a first fan 4 for airflow circulation with the heating component 3 is installed on the upper layer of the positioning frame 1, a surface cooling component 5 for preliminary airflow cooling is fixedly installed on the lower layer of the positioning frame 1, a dehumidification component 6 for airflow drying is fixedly installed on the lower layer of the positioning frame 1, a condensation component 7 for airflow cooling is fixedly installed on the lower layer of the positioning frame 1, and a second fan 8 for airflow circulation with the condensation component 7 is installed on the lower layer of the positioning frame 1; A filter assembly 9 for filtering airflow through a corresponding positioning assembly 10 is installed inside the positioning rack 1. The heating assembly 3, the first fan 4, the surface cooling assembly 5, the dehumidification assembly 6 and the condensation assembly 7 are all core components of the combined air conditioner in the prior art. The filter assembly 9 and the corresponding positioning assembly 10 filter the two layers of the positioning rack 1 respectively, and the controller is used to control the start-up of the first fan 4 and the second fan 8 respectively, so as to extract the air in the positioning rack 1; The surface cooling component 5 includes a second baffle 501, the dehumidification component 6 includes a third baffle 601, the heating component 3 includes a first baffle 301, and the condensation component 7 includes a fourth baffle 701. The second baffle 501, the third baffle 601 and the fourth baffle 701 are arranged in an airflow circulation state. The airflow in the upper layer is transmitted from the filter component 9 to the first baffle 301 for heating, and then exhausted from the first fan 4, while the airflow in the lower layer is transmitted from the filter component 9 to the surface cooling component 5, the dehumidification component 6 and the condensation component 7 respectively, and finally extracted from the second fan 8. The second baffle 501, the first baffle 301, the third baffle 601 and the fourth baffle 701 are concave respectively. Compared with the traditional DC plate, the concave shape can prolong the transmission time of the airflow, so that the time for heating or cooling in the heating component 3, the surface cooling component 5, the dehumidification component 6 and the condensation component 7 is prolonged, so that the airflow reaches the specified temperature and reduces energy loss.

[0023] like Figure 2-Figure 6As shown, the filter assembly 9 includes an auxiliary filter frame 901, an upper air port 902 is provided on the upper layer of the auxiliary filter frame 901, and a lower air port 903 is provided on the lower layer of the auxiliary filter frame 901. The auxiliary filter frame 901 separates the lower air port 903 and the upper air port 902 of the upper and lower layers of the filter assembly 9 to avoid air flow cross-flow, and the air flow conduction direction and size are positioned according to the opening size of the auxiliary filter frame 901 and the upper air port 902. The corresponding adjustment component 10 includes a protective positioning frame 1001 rotatably mounted inside the auxiliary filter frame 901, a motor is fixedly mounted on the top of the protective positioning frame 1001, a diamond positioning frame 1002 is fixedly mounted on the output end of the motor, and two sets of positioning slide columns 100 are hinged on both sides of the diamond positioning frame 1002. 7. A third push plate 1005 is hingedly connected to one side of a group of positioning slides 1007 away from the diamond positioning frame 1002, and a second push plate 1004 is hingedly connected to the other side of the group of positioning slides 1007 away from the diamond positioning frame 1002. The third push plate 1005 and the second push plate 1004 are slidably installed inside the protective positioning frame 1001 through the slide groove of the protective positioning frame 1001. Two groups of positioning slides 1007 are fixedly installed on both sides of the third push plate 1005. The positioning slides 1007 pass through one side of the second push plate 1004 and are fixedly installed with the first push plate 1003. The first push plate 1003 is slidably installed inside the protective positioning frame 1001 through the slide groove of the protective positioning frame 1001. The third push plate 1005, the second push plate 1004, and the third push plate 1005 are fixedly installed on both sides of the third push plate 1005. A plurality of groups of engaging positioning blocks 1008 are fixedly installed on both sides of the push plate 1004 and the first push plate 1003, a conduction tube 1009 is fixedly installed inside one group of the engaging positioning blocks 1008, a positioning slide column 1007 is slidably installed inside the conduction tube 1009, a buffer plate 1006 is fixedly installed on both sides of the first push plate 1003, the second push plate 1004 and the third push plate 1005, a positioning block 1010 is threadedly connected to one side of the engaging positioning block 1008, a dry dust collection box 904 is fixedly installed inside the auxiliary filter frame 901, a dry filter screen 915 is inserted inside the dry dust collection box 904, and a plurality of groups of nozzle frames 912 arranged in an inclined state are fixedly installed inside the auxiliary filter frame 901 , a plurality of heaters 911 are fixedly mounted on the inner wall of the auxiliary filter frame 901, each group of nozzle frames 912 has two, and the two nozzle frames 912 are arranged in a symmetrical state, and the heater 911 dries the inside of the filter assembly 9, and the filter assembly 9 also includes a storage cavity frame 914 fixedly mounted with the bottom of the positioning block 1010, and a spring frame 913 is fixedly mounted inside the storage cavity frame 914, and a filter screen mounting frame 905 is fixedly mounted at the bottom of the spring frame 913, and a filter screen 906 is fixedly mounted inside the filter screen mounting frame 905. When the airflow is transmitted from the upper air outlet 902 or the lower air outlet 903, the motor drives the diamond positioning frame 1002 to rotate, and the diamond positioning frame 1002 rotates along the inner wall of the protective positioning frame 1001,During the rotation of the diamond-shaped positioning frame 1002, the positioning slides 1007 hinged on both sides are deflected outward or inward respectively, and the other end of the two positioning slides 1007 away from the diamond-shaped positioning frame 1002 drives the third pushing plate 1005 and the second pushing plate 1004 to move synchronously, so that the distance between the third pushing plate 1005 and the second pushing plate 1004 becomes larger or smaller. At the same time, the third pushing plate 1005 drives the positioning slides 1007 to slide along the conductive tube 1009, so that the positioning slides 1007 drive the third pushing plate 1005 and the first pushing plate 1003 to slide synchronously through the two sets of engaging positioning blocks 1008 on both sides, and the distance between the third pushing plate 1005 and the first pushing plate 1003 The spacing between the first pushing plate 1003 and the second pushing plate 1004 remains unchanged, while the spacing between the first pushing plate 1003 and the second pushing plate 1004 changes, and the engaging positioning block 1008 drives the filter mounting frame 905 to slide through the storage cavity frame 914. During the sliding process of the filter 906, whenever it moves between a group of nozzle frames 912, the infrared sensing components between a group of nozzle frames 912 sense the trigger components on the surface of the filter mounting frame 905, thereby controlling the water pipe connected to the nozzle frame 912 to release the water flow through the nozzle frame 912 to clean the filter 906. During the sliding process, the filter 906 can give the water droplets adhering to the surface a left and right thrust to thereby improve the collection efficiency of the sewage and cooperate with the drying efficiency of the heater 911; Since the three groups 306 can improve the purification efficiency of the airflow, when the airflow is transmitted to the 306 on the side close to the first fan 4 and the second fan 8, since the airflow is relatively clean after being filtered by the first two groups 306, less dust is transmitted to this 306. At the same time, the nozzle holder 912 is not set on the side of the 306 facing the first fan 4 or the second fan 8. When the 306 here and the 306 in the middle are at the farthest position, the 306 here is only affected by the heater 911. Since the airflow will contact the water flow formed by the nozzle holder 912 during the process of passing through the first two groups 306, although it The purpose of water mist dust reduction is achieved, but the airflow will be relatively humid, and the water mist absorbs the heat emitted by the heater 911, so the heater 911 cannot completely dry the airflow or needs to consume more energy to dry it, which also affects the consumption of the subsequent heating component 3, the surface cooling component 5, the dehumidification component 6 and the condensation component 7. When the filter 906 on the side facing the first fan 4 and the second fan 8 moves to the area only affected by the heater 911, the humidity on its surface is lower, and then when the airflow is transmitted here, it can be better dried by the heater 911, thereby improving the temperature control efficiency of the airflow; Further explanation, two groups of transmission card plates 1011 are fixedly installed on both sides of the positioning card block 1010, and the transmission card plates 1011 are slidably installed inside the sliding cavity. During the sliding process of the positioning card block 1010 driving the filter mounting frame 905 through the storage cavity frame 914, since the transmission card plates 1011 and the positioning card block 1010 are fixedly installed, the transmission card plates 1011 slide synchronously, and the transmission card plates 1011 are always located in the sliding cavity. During the sliding process, the transmission card plates 1011 always block the gap between the protective positioning frame 1001 and the filter component 9, and the corresponding positioning component 10 is always in a relatively sealed state. The airflow and water flow cannot enter the interior of the corresponding positioning component 10, interfere with and damage the electronic components inside it, and extend the service life of the equipment.

[0024] like Figure 7-Figure 10 As shown, an arc-shaped guide hole frame 908 with a plurality of arc-shaped holes is fixedly installed at the bottom of the filter mounting frame 905, a two-way step frame 909 is fixedly installed on the inner wall of the dry dust collecting box 904, and a plurality of groups of conductive balls 910 adapted to the arc-shaped holes are fixedly installed on the top of the two-way step frame 909. An inclined conductive plate 907 is slidably installed on the surface of the dry dust collecting box 904 through a sliding hole. The inclined conductive plate 907 is sleeved on the outer side of the filter mounting frame 905. When the filter mounting frame 905 moves along the two-way step frame 909, due to the plurality of groups of conductive balls 910, The height of the guide ball 910 located on the two-way step frame 909 is the highest in the middle, and the heights of the two sides gradually decrease. When the arc-shaped holes of the arc-shaped guide hole frame 908 move toward the two sides along the central conductive ball 910, the top of the filter mounting frame 905 slides downward from the storage cavity frame 914 under the limit of the spring frame 913. Under the elastic force of the spring frame 913 and gravity, the filter 906 vibrates, and the water droplets on the surface are fully shaken off, thereby improving the drying efficiency, fully shaking off the dust on the surface, making the airflow fresher, and improving the customer experience; Similarly, when the filter mounting frame 905 moves from bottom to top, since the side of the two-way step frame 909 is arc-shaped and the bottom of the arc-shaped hole of the arc-shaped guide hole frame 908 is also arc-shaped, the arc-shaped surface at the bottom of the arc-shaped guide hole frame 908 contacts the arc-shaped surface on the side of the two-way step frame 909 and returns to its original position. With the cooperation of the corresponding adjustment component 10, the filter mounting frame 905 can perform reciprocating left and right swings and up and down vibrations, thereby improving the cleaning effect of dust and sewage.

[0025] Furthermore, the two ends of the two groups of inclined conductive plates 907 are respectively sleeved on the side of the filter mounting frame 905. At the same time, since the inclined conductive plates 907 are sleeved on the outer side of the filter mounting frame 905, the inclined conductive plates 907 move left and right together with the filter mounting frame 905, and the inclined conductive plates 907 are positioned on the dry dust collecting box 904 by the sliding holes, so that when the filter mounting frame 905 moves up and down, the inclined conductive plates 907 remain stationary, so that the two-way step frame 909 and the filter 906 are kept in an isolated state, so as to avoid water droplets entering the two-way step frame 909 and causing pollution. At the same time, due to the guidance of the upper air outlet 902 and the lower air outlet 903, the air flow is located between the inclined conductive plates 907 and the dry dust collecting box 904. The inclined conductive plate 907 is a triangular block, which forms a relatively sealed space with the side wall of the dry dust collection box 904, thereby further preventing dirt from entering the two-way ladder frame 909. The surface of the inclined conductive plate 907 is an inclined surface, so the fallen water droplets are easily transferred to the dry filter screen 915 through the inclined surface. As the inclined conductive plate 907 moves left and right following the 305, the inclined conductive plate 907 pushes the dirt formed by the water droplets and dust attached to the filter screen of the dry filter screen 915 to avoid its accumulation, which causes the dirt to be unable to circulate normally, thereby improving the dirt collection efficiency. The surface of the dry filter 915 can dry the material, improve the drying effect, and facilitate later recycling. When the customer needs to clean it, he only needs to pull out the dry filter 915 from one side of the dry dust collection box 904 for cleaning. Compared with the traditional technology, each filter needs to be disassembled and cleaned. Its installation is relatively simple and the work efficiency is improved.
