Description

Technical Field

[0001] The present invention relates to the technical field of connecting components, and in particular to a connecting component, a shell assembly and an air handling unit. Background Art

[0002] To facilitate processing, transportation and installation, the air handling unit (such as an indoor cabinet air conditioner) can be divided into multiple independent modules according to its function. On the one hand, each module can be processed simultaneously, which improves the processing efficiency; on the other hand, the air handling unit can be decomposed into multiple small modules, which is more conducive to transportation; on the other hand, during installation, if the user's vertical installation space is large, the modules can be stacked vertically to form a complete machine. If the user's vertical installation space is insufficient, air ducts can be used to connect the corresponding modules horizontally, thereby saving vertical installation space.

However, the existing connecting components only consider the use scenario when the modules are stacked, and do not consider the use scenario when the modules may not be stacked together, resulting in low adaptability of the connecting components.

[0106] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0107] In order to facilitate processing, transportation and installation, the air handling unit (such as an indoor cabinet of an air conditioner) can be divided into multiple independent modules according to its function. Each module can be carried separately and assembled during operation. During assembly, each module is connected by a connecting component. On the one hand, the connecting component can connect the two modules, and on the other hand, it can also seal the gap between the two modules, thereby improving the overall sealing effect of the air handling unit. When each module is carried separately, the connecting component can also form a buffer to protect the module connected thereto. The existing connecting component is an annular frame, which is connected between the two modules and respectively connected between the outer shells of the two modules.

[0108] However, the applicant found that in the above scheme, since the connecting component is a separate frame, when the connecting component is installed before the air handling unit is transported, no matter which module the connecting component is installed on, there must be a module without the connecting component installed, which requires an additional protective structure for the module without the connecting component installed to avoid damage during transportation. For this reason, the applicant subsequently divided the connecting component into two frames. During the transportation process, the two frames correspond to the ends of the two modules, and the two frames are spliced ​​and connected during assembly. Specifically, one of the frames is provided with a protrusion and the other frame is provided with a groove. After the two frames are spliced, the protrusion cooperates with the groove to achieve the limit of the two frames, thereby achieving the connection of the two modules. In the above scheme, each module can be connected to a frame, so that each module can be well protected, and at the same time, it is also convenient for the connection of each module. Then, it is subsequently found that in the above scheme, since the protrusion protrudes from the frame, on the one hand, a corresponding depression needs to be set on the buffer of the connecting frame during transportation, so as to achieve the flat placement of the module. On the other hand, when the modules are not stacked together, the structure with the protruding raised portion is not convenient for assembly (an additional groove corresponding to the raised portion needs to be opened on the air duct that cooperates with the raised portion), that is, the structure with the protruding raised portion is more suitable for the connection scenario where the modules are stacked, and is not very suitable for the use scenario where the modules are not stacked.

[0109] In view of this, see Figure 1-Figure 24 , see Figure 1-Figure 18 , this embodiment provides a connecting component 100, which is used for an air handling unit 1. The air handling unit 1 can be an air purifier, a humidifier, an air conditioner, or other device for treating air. The air handling unit 1 is taken as an air conditioner for example. Exemplarily, the air handling unit 1 can be divided into three modules, namely, a purification module 40, a heat exchange module 30, and an air guide module 20 according to function (in other embodiments, it can also be divided into two modules or more than four modules), wherein the heat exchange module 30 can be connected to the purification module 40 at one end and connected to the air guide module 20 at the other end.

[0110] The purification module 40 is used to take in air and purify the introduced air. The air purified by the purification module 40 is introduced into the heat exchange module 30. The heat exchange module 30 exchanges heat with the air. When the air handling unit 1 is in the heating mode, the heat exchange module 30 heats the air. When the air handling unit 1 is in the cooling mode, the heat exchange module 30 cools the air. The heat exchange module 30 guides the air after heat exchange to the air guide module 20. The air guide module 20 generates a driving force, which, on the one hand, enables the external airflow to enter the air handling unit 1 from the purification module 40, and on the other hand, enables the air in the air guide module 20 to be exported. The air guide module 20 can also control the export parameters of the air. The export parameters may include the air export flow rate, export time, and export direction. The air guide module 20 can specifically control the export parameters of the air by controlling the driving force of the air supply component and the swing direction of the air guide plate.

[0111] See also Figure 1 as well as Figure 14-16 In the first installation scenario, the purification module 40, the heat exchange module 30 and the air guide module 20 can be stacked in a straight line, and the heat exchange module 30 is located between the purification module 40 and the air guide module 20 (the air handling unit 1 can be arranged vertically or horizontally, and the vertical arrangement of the air handling unit 1 is used as an example for explanation. When arranged vertically, the purification module 40 can be located at the bottom and the air guide module 20 can be located at the top). At this time, a connecting component 100 is connected between the purification module 40 and the heat exchange module 30, and another connecting component 100 is connected between the air guide module 20 and the heat exchange module 30. The connecting component 100 between the air guide module 20 and the heat exchange module 30 is used as an example for explanation.

[0112] See also Fig.17 In the second installation scenario, when the user's vertical installation space is insufficient, an air duct 50 can be added (the air duct 50 can be a user's own device or a device provided by the manufacturer). The air duct 50 is located at the lower end of the air handling unit 1. The upper end surface of the air duct 50 has two openings. The upper end of the air duct 50 is respectively connected to the heat exchange module 30 and the air guide module 20, and the heat exchange module 30 and the air guide module 20 are correspondingly connected to the above two openings. The external airflow flows down from the purification module 40 to the heat exchange module 30 and continues to flow down to the air duct 50. The airflow in the air duct 50 flows up to the air guide module 20 and is guided upward by the air guide module 20. In this solution, the heat exchange module 30 and the air guide module 20 are arranged in parallel horizontally, so that the vertical arrangement space of the air handling unit 1 is reduced. The existing connection components can only adapt to the first installation scenario and are difficult to adapt to the second installation scenario.

[0113] See also Figure 1 , Fig.15 , Figure 2-Figure 5The air handling unit 1 in this embodiment includes a first housing 200 and a second housing 300, and the first housing 200 and the second housing 300 may both be annular. When the connecting component 100 is used to connect the air guide module 20 and the heat exchange module 30, the first housing 200 may be the outer shell of the air guide module 20, and the second housing 300 may be the outer shell of the heat exchange module 30. The connecting component 100 includes a first frame 110, a second frame 120 and a stopper 130.

[0114] See also Figure 2-Figure 4 The first frame 110 is suitable for connecting one end of the first housing 200 (specifically, one end of the first housing 200 for connecting to the second housing 300), and the first frame 110 is in a ring shape arranged around the first axis a (after the first frame 110 is connected to the first housing 200, the first axis a can be the central axis of the first housing 200). The first frame 110 has a first end 111 and a second end 112 arranged relatively in a direction parallel to the first axis a, and the first end 111 of the first frame 110 is suitable for connecting one end of the first housing 200. The connection method between the first end 111 and the first housing 200 depends on actual needs, and the two can be snap-fitted, interference-fitted, threaded, glued, etc. The second end 112 of the first frame 110 is provided with a first limiting groove 1121, and the second limiting groove 1221 is used to cooperate with the limiting member 130.

[0115] The second frame 120 is suitable for connecting one end of the second housing 300 (specifically, the second housing 300 is used to connect one end of the first housing 200), and the second frame 120 is in a ring shape arranged around the second axis b (when the second frame 120 is connected to the second housing 300, the second axis b can be the central axis of the second housing 300, and when the second frame 120 is connected to the first frame 110, the first axis a can coincide with the second axis b). The second frame 120 has a third end 121 and a fourth end 122 arranged relatively in a direction parallel to the second axis b, and the third end 121 is suitable for connecting one end of the second housing 300. The connection method of the third end 121 and the second housing 300 depends on actual needs, and the two can be snap-fitted, interference-fitted, threaded, glued, etc. The fourth end 122 is provided with a second limiting groove 1221, and the fourth end 122 is suitable for connecting to the second end 112. When the fourth end 122 is connected to the second end 112, the second limiting groove 1221 can be connected to the first limiting groove 1121, and the second limiting groove 1221 is suitable for cooperating with the limiting member 130.

[0116] The limiting member 130 is adapted to have one end extend into the first limiting groove 1121 and the other end extend into the second limiting groove 1221 after the second end 112 is connected to the fourth end 122, so as to position the first frame 110 and the second frame 120. When one end of the limiting member 130 extends into the first limiting groove 1121 and the other end extends into the second limiting groove 1221, it is possible to make it difficult for the first frame 110 and the second frame 120 to move relative to each other in a direction perpendicular to the first axis a or the second axis b.

[0117] See also Figure 1 as well as Figure 14-16 In the first installation scenario, the connecting component 100 is arranged between the air guide module 20 and the heat exchange module 30 (in other embodiments, it can also be arranged between the heat exchange module 30 and the purification module 40), the first frame 110 is connected to the first shell 200, the second frame 120 is connected to the second shell 300, and the limiting member 130 is arranged between the first frame 110 and the second frame 120, and one end of the limiting member 130 extends into the first limiting groove 1121, and the other end extends into the second limiting groove 1221. In this scenario, since the connecting component 100 is divided into two main parts, the first frame body 110 and the second frame body 120, the two main parts are correspondingly connected to the first shell 200 and the second shell 300. Compared with the existing structure in which the connecting component is one main component and is arranged between the first shell and the second shell, the connecting component 100 in this embodiment can first be separately assembled to the first shell 200 and the second shell 300 when the two modules of the air handling unit 1 are assembled and transported, so that the subsequent assembly of the two modules is more convenient.

[0118] See also Fig.17In the second installation scenario, the air handling unit 1 is connected to the air duct 50, the air guide module 20 and the heat exchange module 30 are both connected above the air duct 50, and the air duct 50 is used to conduct the air guide module 20 and the heat exchange module 30. The first frame 110 is connected to one end of the first shell 200 for conducting with the second shell 300 (in the structure shown in the figure, the first frame 110 is connected to the lower end of the first shell 200), the second frame 120 is connected to one end of the second shell 300 for conducting with the first shell 200 (in the structure shown in the figure, the second frame 120 is connected to the lower end of the second shell 300), and the second end 112 of the first frame 110 is connected to the air duct 50, and the second end 112 of the first frame 110 can be clamped, glued, threaded or welded to the air duct 50. The fourth end 122 of the second frame 120 is connected to the air duct 50, and the fourth end 122 of the second frame 120 can be clamped, glued, threaded or welded to the air duct 50. In the connection component 100 in this embodiment, since the limiting component is separately provided, the limiting component 130 can be separated from the first frame 110 and the second frame 120 in this installation scenario. Compared with the existing structure in which the first frame is provided with a protrusion, the second frame is provided with a groove, and the protrusion of the first frame cooperates with the groove on the second frame, in the solution in this embodiment, after the limiting component 130 is removed, both the first frame 110 and the second frame 120 can be better placed flat on the upper end of the air duct 50, so that the first frame 110 and the second frame 120 can be connected to the air duct 50. In the existing solution, due to the protruding structure of the protruding part, the first frame is difficult to be placed flat on the air duct, and an additional groove for accommodating the protruding part needs to be opened on the air duct. The opening position of the groove also needs to be accurately positioned according to the position of the protruding part, which is complicated. In comparison, the connection component 100 in this embodiment can remove the limiter 130, which can better adapt to the above installation scenario.

[0119] Since the connection methods of the first frame 110 and the second frame 120 are different in different installation scenarios, for the convenience of description, the following is an example of a structure in which the modules of the air handling unit 1 are stacked along a straight line and stacked along a vertical straight line (in other embodiments, they can also be stacked along a horizontal straight line). In this structure, the first frame 110 is connected to the second frame 120, and the limit member 130 is arranged between the first frame 110 and the second frame 120 with one end extending into the first limit groove 1121 and the other end extending into the second limit groove 1221. Since the first axis a coincides with the second axis b at this time, the first axis a is used as a position reference in the following text.

[0120] See also Figure 4-Figure 7After the limiting member 130 is inserted into the first limiting groove 1121 and the second limiting groove 1221, it can be connected to the first frame body 110 and the second frame body 120 in other ways. In some embodiments, the connecting component 100 also includes a connecting member (not shown in the figure), the limiting member 130 includes a first connecting structure 131, and the second end 112 is provided with a second connecting structure 1123, and the connecting member is connected to the first connecting structure 131 and the second connecting structure 1123 respectively. In this solution, the first connecting structure 131 and the second connecting structure 1123 are connected by the connecting member, so that the limiting member 130 is not only inserted into the second end 112 of the first frame body 110, but the two are also connected in other ways, and the connection between the limiting member 130 and the first frame body 110 is more stable.

[0121] The specific structures of the first connection structure 131, the second connection structure 1123 and the connecting member can be determined according to the specific connection form of the first frame 110, the stopper 130 and the connecting member. Specifically, the stopper 130 can be connected with the second end 112 of the first frame 110 by snap connection, interference fit connection or threaded connection. Exemplarily, when the stopper 130 is threadedly connected with the second end 112 of the first frame 110, the connecting member can be a component such as a screw or a bolt, and the first connection structure 131 and the second connection structure 1123 can both be threaded holes, and the connecting member can be threadedly matched with the above two threaded holes to achieve the threaded connection between the stopper 130 and the first frame 110. In other embodiments, the limit member 130 can also be connected to the fourth end 122 of the second frame body 120 (specifically, it can be a threaded connection), so that the limit member 130 can not only be used to locate the relative position of the first frame body 110 and the second frame body 120 along a direction perpendicular to the first axis a, but also can be used to locate the relative position of the first frame body 110 and the second frame body 120 along a direction parallel to the first axis a.

[0122] In some embodiments, the connector can also connect the stopper 130, the first frame 110 and the first shell 200 at the same time. Exemplarily, when the connector is threadedly connected to the stopper 130, the first frame 110 and the first shell 200, the connector can be a screw, the first connection structure 131 and the second connection structure 1123 can be through holes, the first shell 200 is provided with a threaded hole, and the connector passes through the stopper 130 and the through hole on the first frame 110 to be threadedly connected with the threaded hole on the first shell 200. In this solution, the connector can connect the stopper 130 and the first frame 110 while also connecting the first frame 110 and the first shell 200. When the first frame 110 and the first shell 200 are connected only by the connector, the connection efficiency of the connecting component 100 and the first shell 200 is higher; when the first frame 110 and the first shell 200 are also connected by other methods, the connection between the first frame 110 and the first shell 200 is more stable. In a further embodiment, the connector may also connect the second frame 120 and the second shell 300 at the same time, which will not be described in detail here.

[0123] The second connection structure 1123 can be located at any suitable position of the first frame body 110. Specifically, the second connection structure 1123 can be arranged in the first limiting groove 1121, or can be arranged outside the first limiting groove 1121. For example, when the first connection structure 131 is a through hole, a through hole can be opened in the bottom wall of the first limiting groove 1121, or a through hole can be opened at a position beside the first limiting groove 1121. The second connection structure 1123 is arranged correspondingly according to the position of the first connection structure 131. When the first connection structure 131 is arranged in the first limiting groove 1121, the second connection structure 1123 can be arranged at a position where the limiting member 130 is used to extend into the first limiting groove 1121. When the first connecting structure 131 is arranged outside the first limiting groove 1121, the second connecting structure 1123 can be arranged at the part of the limiting member 130 located outside the first limiting groove 1121. At this time, other grooves can be opened at the second end 112 of the first frame body 110 to accommodate the second connecting structure 1123, thereby avoiding position interference between the second connecting structure 1123 and the second frame body 120.

[0124] The specific arrangement position of the first limiting groove 1121 at the second end 112 depends on actual needs. Figure 2-Figure 5In some embodiments, the first frame 110 includes a first annular frame 113 and a first boss 114. The first annular frame 113 is arranged around the first axis a, and the first annular frame 113 is used to connect the first housing 200 and the second frame 120. The inner side wall of the first annular frame 113 close to the first axis a is connected to the first boss 114 (that is, the first boss 114 is a protrusion provided on the inner side wall of the first annular frame 113 and protruding in the direction close to the first axis a), and the first limiting groove 1121 is at least partially provided on the first boss 114. In other words, the first boss 114 at least partially belongs to the second end 112, and the first limiting groove 1121 can be completely located at the part of the first boss 114 belonging to the second end 112, or it can be partially located at the part of the first boss 114 belonging to the second end 112, and the other part is located at the part of the first annular frame 113 belonging to the second end 112. In this solution, compared with the structure in which the first limiting groove 1121 is completely provided at the part of the first annular frame 113 belonging to the second end 112, the opening area of ​​the second end 112 of the first annular frame 113 is smaller, and the contact area between the first annular frame 113 and the second frame body 120 is larger, so that the connection between the first annular frame 113 and the second frame body 120 is more stable. In addition, since the first boss 114 is provided at the inner side wall of the first annular frame 113, compared with the structure in which the first boss 114 is provided at the outer side wall of the first annular frame 113, the appearance of the connecting component 100 is neater, dust accumulation can be reduced, and it is convenient to maintain.

[0125] In some embodiments, the first boss 114 may be disposed on the side of the first annular frame 113. Figure 2-Figure 5, the first annular frame 113 includes four sides, and the first boss 114 can be arranged at any one of the sides of the first annular frame 113. In other embodiments, the first boss 114 can be arranged at a corner position of the first annular frame 113, the first annular frame 113 includes four sides, and the four sides are connected end to end to form four corner positions, and the first boss 114 can be arranged at any one of the four corner positions. When the first limiting groove 1121 is at least partially arranged on the first boss 114, the shapes of the first limiting groove 1121 and the limiting member 130 can be adapted to the shape of the first boss 114. Specifically, in some embodiments, the first boss 114 is arranged on one of the sides of the first annular frame 113, the first limiting groove 1121 is located on the side of the first frame body 110, and the part of the limiting member 130 suitable for extending into the first limiting groove 1121 is in the shape of a straight strip. In other embodiments, the first boss 114 may be disposed at any one of the four corner positions, the first limiting groove 1121 is located at the corner end of the first frame body 110, and the portion of the limiting member 130 adapted to extend into the first limiting groove 1121 is curved. Of course, in other embodiments, when the first limiting groove 1121 is completely disposed on the first annular frame 113, the first limiting groove 1121 may also be disposed at the side or corner position of the first annular frame 113, and the portion of the limiting member 130 disposed in the first limiting groove 1121 may also be correspondingly straight or curved, which will not be described in detail here.

[0126] The specific arrangement position of the second limiting groove 1221 at the fourth end 122 depends on actual needs. Figure 2-Figure 5In some embodiments, the second frame 120 includes a second annular frame 123 and a second boss 124. The second annular frame 123 is arranged around the second axis b, and the second annular frame 123 is used to connect the second housing 300 and the first frame 110. The inner side wall of the second annular frame 123 close to the second axis b is connected to the second boss 124 (that is, the second boss 124 is a protrusion provided on the inner side wall of the second annular frame 123 and protruding in the direction close to the second axis b), and the second limiting groove 1221 is at least partially provided on the second boss 124. In other words, the second boss 124 at least partially belongs to the fourth end 122, and the second limiting groove 1221 can be completely located at the part of the second boss 124 belonging to the fourth end 122, or it can be partially located at the part of the second boss 124 belonging to the fourth end 122, and the other part is located at the part of the second annular frame 123 belonging to the fourth end 122. In this solution, compared with the structure in which the second limiting groove 1221 is completely provided at the part of the second annular frame 123 belonging to the fourth end 122, the opening area of ​​the fourth end 122 of the second annular frame 123 is smaller, and the contact area between the second annular frame 123 and the first frame body 110 is larger, so that the connection between the second annular frame 123 and the first frame body 110 is more stable. In addition, since the second boss 124 is provided on the inner side wall of the second annular frame 123, compared with the structure in which the second boss 124 is provided on the outer side wall of the second annular frame 123, the appearance of the connecting component 100 is neater, dust accumulation can be reduced, and it is convenient to maintain.

[0127] In some embodiments, the second boss 124 may be disposed on the side of the second annular frame 123. Figure 2-Figure 5, the second annular frame 123 includes four sides, and the second boss 124 can be arranged at any one of the sides of the second annular frame 123. In other embodiments, the second boss 124 can be arranged at a corner position of the second annular frame 123, the second annular frame 123 includes four sides, and the four sides are connected end to end to form four corner positions, and the second boss 124 can be arranged at any one of the four corner positions. When the second limiting groove 1221 is at least partially arranged on the second boss 124, the shapes of the second limiting groove 1221 and the limiting member 130 can be adapted to the shape of the second boss 124. Specifically, in some embodiments, the second boss 124 is arranged on one of the sides of the second annular frame 123, the second limiting groove 1221 is located on the side of the second frame body 120, and the part of the limiting member 130 suitable for extending into the second limiting groove 1221 is in the shape of a straight strip. In other embodiments, the second boss 124 may be disposed at any one of the four corner positions, the second limiting groove 1221 is located at the corner end of the second frame body 120, and the portion of the limiting member 130 adapted to extend into the second limiting groove 1221 is curved. Of course, in other embodiments, when the second limiting groove 1221 is completely disposed on the second annular frame 123, the second limiting groove 1221 may also be disposed at the side or corner position of the second annular frame 123, and the portion of the limiting member 130 disposed in the second limiting groove 1221 may also be correspondingly straight or curved, which will not be described in detail here.

[0128] See also Figure 6-Figure 7 as well as Figure 14-15In some embodiments, the first frame 110 includes a first main body 115 and a first stopper 1161 distributed along the circumference of the first axis a. The two ends of the first stopper 1161 are respectively connected to the two ends of the first main body 115 along the circumference of the first axis a. Specifically, the two ends of the first main body 115 along the circumference of the first axis a are respectively provided with third limiting grooves 1151, and the two third limiting grooves 1151 both penetrate the second end 112, and the two ends of the first stopper 1161 along the circumference of the first axis a are respectively provided in the two third limiting grooves 1151. In this solution, the first frame 110 can be assembled from at least two parts. Compared with the integral processing of the first frame 110, the mold size is smaller and the processing difficulty is lower. Furthermore, since the first baffle 1161 and the first main body 115 are spliced ​​and connected rather than integrally connected, the first baffle 1161 and the first main body 115 can be processed with two different materials, wherein the first main body 115 can be processed with plastic, which is more convenient to mold and has lower cost. The first baffle 1161 can be processed with metal parts, which has higher structural strength and longer service life. When the first baffle 1161 is set at the front end of the air handling unit 1, the first baffle 1161 is not easy to reduce the aesthetic appearance of the appearance of the air handling unit 1 due to aging. Exemplarily, when the first frame 110 is in a rectangular ring shape, the first frame 110 may include four sides, wherein the first baffle 1161 may be one of the sides of the first frame 110, and the first main body 115 is a whole formed by combining the other three sides of the first frame 110.

[0129] It should be noted that the structural division of the first annular frame 113 and the first boss 114 is different from the structural division standard of the first main body 115 and the first stop bar 1161. The first main body 115 is the portion of the first frame 110 without the first stop bar 1161, and the first annular frame 113 is the portion of the first frame 110 without the first boss 114. When the first boss 114 is provided on the first main body 115, the first annular frame 113 includes the portion of the first main body 115 without the first boss 114 and the first stop bar 1161. When the first boss 114 is provided on the first stop bar 1161, the first annular frame 113 includes the portion of the first stop bar 1161 without the first boss 114 and the first main body 115.

[0130] See also Figure 6-Figure 7 as well as Figure 14-15The second frame 120 includes a second main body 125 and a second stopper 1261 distributed along the circumference of the first axis a. The two ends of the second stopper 1261 are respectively connected to the two ends of the second main body 125 along the circumference of the first axis a. Specifically, the second main body 125 is provided with fourth limiting grooves 1251 at both ends along the circumference of the second axis b. Both fourth limiting grooves 1251 penetrate the fourth end 122. Both ends of the second stopper 1261 along the circumference of the second axis b are provided in the two fourth limiting grooves 1251 in a one-to-one correspondence. The second stopper 1261 is suitable for abutting against the first stopper 1161. In this solution, the second frame 120 can be assembled from at least two parts. Compared with the overall one-piece processing of the second frame 120, the mold size is smaller and the processing difficulty is lower. Furthermore, since the second baffle 1261 and the second main body 125 are spliced ​​and connected rather than integrally connected, the second baffle 1261 and the second main body 125 can be processed with two different materials, wherein the second main body 125 can be processed with plastic, which is more convenient to mold and has lower cost. The second baffle 1261 can be processed with metal parts, which has higher structural strength and longer service life. When the second baffle 1261 is set at the front end of the air handling unit 1, the second baffle 1261 is not easy to reduce the aesthetic appearance of the appearance of the air handling unit 1 due to aging. Exemplarily, when the second frame 120 is in a rectangular ring shape, the second frame 120 may include four sides, wherein the second baffle 1261 may be one of the sides of the second frame 120, and the second main body 125 is a whole formed by combining the other three sides of the second frame 120.

[0131] In order to adapt to different needs, the air handling unit 1 can have different sizes. In order to reduce costs, the air handling unit 1 can be changed in size only in one direction, thereby reducing the number of parts of the air handling unit 1 whose size changes. For example, in order to adapt to different refrigeration needs, air handling units 1 of different powers can be set, and the space sizes of air handling units 1 of different powers are different. For air handling units 1 with a rectangular cross-section, the vertical height dimensions of each air handling unit 1 of different sizes can be kept unchanged, the front and rear longitudinal dimensions can be kept unchanged, and the left and right lateral dimensions of the air handling unit 1 can be changed. That is, the left and right lateral dimensions of a small air handling unit 1 are small, the left and right lateral dimensions of a medium-sized air handling unit 1 are medium, and the left and right lateral dimensions of a large air handling unit 1 are large, and the other external dimensions of the three are the same.

[0132] In order to adapt to the size change of the above-mentioned air handling unit 1, in some embodiments, a plurality of connecting components 100 with different shapes can be provided accordingly. In other embodiments, in order to reduce the mold cost, the same set of connecting components 100 can be adapted to air handling units 1 of different sizes at the same time by providing an adaptor block. Figure 6-Figure 7 as well as Figure 14-15 The first frame 110 further includes a first adapter block 1171 and a third stop bar 1162 longer than the first stop bar 1161. The first main body 115 includes a first rod 1152 opposite to the first stop bar 1161, and the first rod 1152 includes a first section 11521 and a second section 11522, that is, the first rod 1152 consists of two parts that can be separated from each other. The second frame 120 further includes a second adapter block 1271 and a fourth stop bar 1262 longer than the second stop bar 1261, and the second main body 125 includes a second rod 1252 opposite to the second stop bar 1261, and the second rod 1252 includes a third section 12521 and a fourth section 12522, that is, the second rod 1252 consists of two parts that can be separated from each other.

[0133] The connecting component 100 has a first working state and a second working state. Figure 6-Figure 7 as well as Figure 14-15 In the first working state, the first main body 115 is connected to the first stopper 1161, the first section 11521 abuts the second section 11522, the second main body 125 is connected to the second stopper 1261, and the third section 12521 abuts the fourth section 12522. In this solution, the connecting component 100 can be adapted to a smaller air handling unit 1. In the second working state, the first main body 115 is connected to the third stopper 1162, the first section 11521 and the second section 11522 are connected to the first adapter block 1171, the second main body 125 is connected to the fourth stopper 1262, and the third section 12521 and the fourth section 12522 are connected to the second adapter block 1271. In this working state, the difference between the length of the third stopper 1162 and the length of the first stopper 1161 is equal to the length of the first adapter block 1171, and the difference between the length of the fourth stopper 1262 and the length of the second stopper 1261 is equal to the length of the second adapter block 1271. In this solution, the connecting component 100 can be adapted to a medium-sized air handling unit 1 .

[0134] See also Figure 6-Figure 7 as well as Fig.16, the connecting component 100 may also have other working states to adapt to air handling units 1 of other sizes. In this working state, the first frame 110 may also include a fifth bar 1163, the length of which is longer than the third bar 1162. The first frame 110 may also include a third adapter block 1172, the length of which is longer than the first adapter block 1171. The second frame 120 may also include a sixth bar 1263, the length of which is longer than the fourth bar 1262. The second frame 120 may also include a fourth adapter block 1272, the length of which is longer than the second adapter block 1271. In this working state of the connecting component 100, the first main body 115 is connected to the fifth stopper 1163, and the third adapter block 1172 is arranged between the first section 11521 and the second end 112; the second main body 125 is connected to the sixth stopper 1263, and the fourth adapter block 1272 is connected between the third section 12521 and the fourth section 12522. The fifth stopper 1163 and the sixth stopper 1263 abut against each other. In this working state, the difference between the length of the fifth stopper 1163 and the length of the first stopper 1161 is equal to the length of the third adapter block 1172, and the difference between the length of the sixth stopper 1263 and the length of the second stopper 1261 is equal to the length of the fourth adapter block 1272.

[0135] The specific number of adapter blocks may correspond to the number of air handling units 1 that the connection component 100 actually needs to adapt. When two air handling units 1 of different sizes need to be adapted, the connection component 100 may include only two adapter blocks, namely, the first adapter block 1171 and the second adapter block 1271. When three air handling units 1 of different sizes need to be adapted, the connection component 100 may include four adapter blocks, namely, the first adapter block 1171, the second adapter block 1271, the third adapter block 1172, and the fourth adapter block 1272.

[0136] The relative position relationship between the first adapter block 1171 and the second adapter block 1271 can be determined according to actual needs. In some embodiments, the first adapter block 1171 and the second adapter block 1271 do not overlap in the direction parallel to the first axis a. In other embodiments, the first adapter block 1171 and the second adapter block 1271 partially overlap in the direction parallel to the first axis a. In the above two embodiments, the first adapter block 1171 and the second adapter block 1271 can be well positioned in the direction parallel to the first axis a. In some embodiments, see Figure 6-Figure 9, the first adapter block 1171 and the second adapter block 1271 completely overlap in the direction parallel to the first axis a. In this scheme, the shapes of the first adapter block 1171 and the second adapter block 1271 can be exactly the same, and the shapes of the first main body 115 and the second main body 125 can be exactly the same. Using a set of molds, the first adapter block 1171 and the second adapter block 1271 can be processed and formed at the same time, and using a set of molds can be processed and formed at the same time. The processing cost of the connecting component 100 is reduced and the processing efficiency is improved. Further, the first frame 110 and the second frame 120 can be completely the same in structure, so that the first frame 110 and the second frame 120 (two frames of the same structure, wherein the frame connected to the first shell 200 is the aforementioned first frame 110, and the frame connected to the second shell 300 is the aforementioned second frame 120) can be processed and formed at the same time using the same set of molds, with lower processing costs and higher processing efficiency.

[0137] See also Figure 8-Figure 9 In some embodiments, first blocks 11711 may be respectively provided at both ends of the first adapter block 1171, and grooves with openings facing away from the second frame body 120 may be respectively provided at the ends of the first section 11521 and the second section 11522, and two first blocks 11711 may be respectively provided in the two grooves, thereby realizing the connection between the first adapter block 1171 and the first section 11521 and the second section 11522. Similarly, second blocks 12711 may be respectively provided at both ends of the second adapter block 1271, and grooves with openings facing away from the first frame body 110 may be respectively provided at the ends of the third section 12521 and the fourth section 12522, and two second blocks 12711 may be respectively provided in the two grooves, thereby realizing the connection between the second adapter block 1271 and the third section 12521 and the fourth section 12522.

[0138] See also Fig.18In some embodiments, the first main body 115 includes a first rod 1152 opposite to the first stop bar 1161, the first rod 1152 includes a first section 11521, a first middle section 11523 and a second section 11522, one end of the first middle section 11523 is detachably connected to the first section 11521, and the other end is detachably connected to the second section 11522. The second main body 125 includes a second rod 1252 opposite to the second stop bar 1261, the second rod 1252 includes a third section 12521, a second middle section 12523 and a fourth section 12522, one end of the second middle section 12523 is detachably connected to the third section 12521, and the other end is detachably connected to the fourth section 12522. The difference between this embodiment and the previous embodiment is that the connecting component 100 does not need to be adapted to air handling units 1 of different sizes. In this solution, the annular component can be divided into at least four parts for separate processing during processing. Compared with the connection component 100 being an annular whole and being processed by a mold, the connection component 100 in this embodiment can be processed by multiple smaller molds, which reduces the difficulty of mold manufacturing. And because the middle part of the mold for processing an annular component does not participate in the shaping of the product, the annular component is divided into at least four parts along the circumferential direction for separate processing, and the part of the mold for processing the part that does not participate in the shaping is reduced, so that the utilization rate of the mold material is higher, and the material cost of the mold is reduced overall.

[0139] The applicant has discovered that when the first end 111 is configured to be flat and in a structural arrangement in which the flat structure fits the first shell 200, when the material of the first end 111 is relatively soft, although the fit between the first end 111 and the first shell 200 is relatively good and the sealing between the first end 111 and the first shell 200 is relatively good, the structural strength of the first frame 110 is relatively poor and the fitting clearance is difficult to adjust. When the material of the first end 111 is relatively hard, although the fitting clearance between the first end 111 and the first shell 200 is easy to adjust, the two harder planes are difficult to fit tightly, so that a gap is likely to exist between the first end 111 of the first frame 110 and the first shell 200, resulting in poor airtightness between the first end 111 and the first shell 200. In order to solve the above problems, see Figure 10-13In some embodiments, the first end 111 is provided with a first rib 1111, the thickness direction of the first rib 1111 is perpendicular to the first axis a, and the first rib 1111 is suitable for abutting the first shell 200. In this solution, the side of the first rib 1111 perpendicular to the thickness direction abuts the first shell 200. Since the contact area between the first rib 1111 and the first shell 200 is small, even if the first rib 1111 is made of a harder material, it is not easy to generate a gap between the first rib 1111 and the first shell 200. And when the first rib 1111 is made of a harder material, the structural strength of the first frame 110 can also be guaranteed. In order to further improve the structural strength of the first frame 110, a plurality of first ribs 1111 can be provided, and each first rib 1111 is arranged at intervals in a direction perpendicular to the first axis a.

[0140] See also Figure 10-13 In some embodiments, the second end 112 is provided with a second rib 1211, the thickness direction of the second rib 1211 is perpendicular to the second axis b, and the second rib 1211 is suitable for abutting the second shell 300. Similarly, in this solution, the side of the second rib 1211 perpendicular to the thickness direction abuts the second shell 300. Since the contact area between the second rib 1211 and the second shell 300 is small, even if the second rib 1211 is made of a harder material, it is not easy to generate a gap between the second rib 1211 and the second shell 300. And when the second rib 1211 is made of a harder material, the structural strength of the second frame 120 can also be guaranteed. In order to further improve the structural strength of the second frame 120, a plurality of second ribs 1211 can be provided, and each second rib 1211 is arranged at intervals in a direction perpendicular to the first axis a.

[0141] In order to improve the sealing effect between the first frame body 110 and the second frame body 120, see Figure 10-13In some embodiments, the second end 112 is provided with a first annular groove 1122 arranged around the first axis a, and the fourth end 122 is provided with a second annular groove 1222 arranged around the second axis b, and the first annular groove 1122 and the second annular groove 1222 are configured to communicate with each other after the second end 112 is connected to the fourth end 122. The connecting component 100 further includes a filling portion 140, which is suitable for filling the space formed by the first annular groove 1122 and the second annular groove 1222 after the second end 112 is connected to the fourth end 122. In this solution, when the first frame body 110 is connected to the second frame body 120, an annular groove body is formed between the first frame body 110 and the second frame body 120. The annular groove body is composed of a first annular groove 1122 and a second annular groove 1222. The annular groove body is filled with a filling part 140. The filling part 140 can be made of foam or silicone. The filling part 140 can be compressed by the first frame body 110 and the second frame, so that the filling part 140 fills the space between the first frame body 110 and the second frame body 120, thereby improving the sealing effect between the first frame body 110 and the second frame body 120.

[0142] See also Figure 1-Figure 24 , see Figure 19-Figure 24 The embodiment of the second aspect of the present application further provides a connecting component 100, which is used for an air handling unit 1. The air handling unit 1 includes a first shell 200 and a second shell 300. Fig.19 , the connecting component 100 is in a ring shape arranged around the third axis. Specifically, the connecting component 100 can be in a circular ring shape, a rectangular ring shape or an elliptical ring shape. The specific shape of the connecting component 100 depends on the appearance of the first shell 200 and the second shell 300 that are adapted to be matched. The following is an example in which the first shell 200 and the second shell 300 are both rectangular frames and the connecting component 100 is in a rectangular ring shape. One end of the connecting component 100 parallel to the third axis is suitable for connecting one end of the first shell 200, and the other end is suitable for connecting one end of the second shell 300. The connecting component 100 includes a first body 151, a second body 152, a first connecting block 161 and a second connecting block 162.

[0143] See also Fig.19, the first body 151 is arranged around the third axis, and the first body 151 includes a first connection end 1511 and a second connection end 1512 arranged relatively along the circumferential direction of the third axis. The second body 152 is arranged around the third axis, and the second body 152 includes a third connection end 1521 opposite to the first connection end 1511 and a fourth connection end 1522 opposite to the second connection end 1512. The angles of the first body 151 and the second body 152 around the third axis depend on actual needs. In this embodiment, the angles of the first body 151 and the second body 152 around the third axis are both greater than ninety degrees. It should be noted that the angle between the vertical line from the first connection end 1511 to the third axis and the vertical line from the second connection end 1512 to the third axis is the angle of the first body 151 around the third axis, and the angle between the vertical line from the third connection end 1521 to the third axis and the vertical line from the fourth connection end 1522 to the third axis is the angle of the second body 152 around the third axis. The first body 151 and the second body 152 are arranged opposite to each other in a direction perpendicular to the third axis. When the connecting component 100 connects the first shell and the second shell 300, one end of the first body 151 is connected to the first shell 200 and the other end is connected to the second shell 300; one end of the second body 152 is connected to the first shell 200 and the other end is connected to the second shell 300.

[0144] One end of the first connection block 161 is detachably connected to the first connection end 1511, and the other end is detachably connected to the third connection end 1521. Specifically, the first connection block 161 can be threaded, clamped, or riveted to the first body 151 and the second body 152. One end of the second connection block 162 is detachably connected to the second connection end 1512, and the other end is detachably connected to the fourth connection end 1522. Specifically, the second connection block 162 can be threaded, clamped, or riveted to the first body 151 and the second body 152. When the connecting component 100 connects the first shell 200 and the second shell 300, one end of the first connection block 161 is connected to the first shell 200, and the other end is connected to the second shell 300; one end of the second connection block 162 is connected to the first shell 200, and the other end is connected to the second shell 300. The first body 151, the first connection block 161, the second body 152 and the second connection block 162 are sequentially connected end to end along the circumferential direction of the third axis to form an annular frame, and the first connection block 161 and the second connection block 162 are respectively located on opposite sides of the connecting component 100 along a direction perpendicular to the third axis. Exemplarily, when the connecting component 100 is in a rectangular ring shape, it has four sides, and the first connection block 161 and the second connection block 162 are respectively located on two opposite sides thereof.

[0145] In this embodiment, the annular connecting component 100 can be divided into at least four parts, namely, the first body 151, the first connecting block 161, the second body 152 and the second connecting block 162, for separate processing. Compared with the connecting component 100 being an annular whole and being processed by a mold, the connecting component 100 in this embodiment can be processed by a plurality of smaller molds, which reduces the difficulty of mold manufacturing. And since the middle part of the mold for processing an annular component does not participate in the shaping of the product, an annular component is circumferentially split into at least four parts for separate processing, and the part of the mold for processing the part that does not participate in the shaping is reduced, so that the utilization rate of the mold material is higher, and the material cost of the mold is reduced as a whole. And the part splitting method in which the first connecting block 161 and the second connecting block 162 are located on two opposite sides of the connecting component 100 can make the encircling angle of each part of the connecting component 100 smaller, which can further improve the utilization rate of the mold material.

[0146] See also Figure 19-20 In some embodiments, along the circumference of the third axis, the length of the first connection block 161 is equal to the length of the second connection block 162, and the first connection end 1511 is suitable for connecting with the third connection end 1521, and the second connection end 1512 is suitable for connecting with the fourth connection end 1522. In this solution, the first connection block 161 and the second connection block 162 can be removed, and the first connection end 1511 is connected to the third connection end 1521, and the second connection end 1512 is connected to the fourth connection end 1522, that is, the first body 151 and the second body 152 are connected to each other and form a ring-shaped frame structure. This solution allows the connection component 100 to be adapted to the air handling unit 1 with a smaller size in one direction. It should be noted that when the connecting component 100 is in the shape of a rectangular ring and the first connecting block 161 and the second connecting block 162 are both in the shape of straight blocks, the circumferential length of the first connecting block 161 along the third axis is the length of the first connecting block 161 along the side parallel to the corresponding connecting component 100, and the circumferential length of the second connecting block 162 along the third axis is the length of the other side parallel to the connecting component 100.

[0147] See also Figure 21-23In other embodiments, along the circumference of the third axis, the length of the first connection block 161 is less than the length of the second connection block 162, and the first connection end 1511 is suitable for connecting with the third connection end 1521. The connecting component 100 also includes a third connection block 163, one end of the third connection block 163 is suitable for connecting with the second connection end 1512, and the other end is suitable for connecting with the fourth connection end 1522. Along the circumference of the third axis, the difference between the length of the second connection block 162 and the length of the third connection block 163 is equal to the length of the first connection block 161. In this solution, the first connection block 161 and the second connection block 162 can be removed, so that the first connection end 1511 is connected to the third connection end 1521, and the third connection block 163 is respectively connected to the second connection end 1512 and the fourth connection end 1522, that is, the first body 151, the second body 152 and the third connection block 163 are connected to each other and form a ring-shaped frame structure. In this solution, while improving the adaptability of the connecting component 100, the size of the first body 151 and the second body 152 can be minimized, thereby reducing the size of the mold for processing the first body 151 and the second body 152, reducing the difficulty of mold processing and reducing the material cost of the mold. Referring to the figure, in a further embodiment, the connecting component 100 is in a rectangular ring shape, and the connecting component 100 includes four side rods, one of which is the second connection block 162, and the side rod opposite to the second connection block 162 includes the first connection block 161. That is, in this embodiment, when the first body 151, the second body 152, the first connecting block 161 and the second connecting block 162 are connected to form a ring-shaped frame structure, the length of the second connecting block 162 is equal to the length of one of the sides of the connecting component 100. When the first body 151, the second body 152 and the third connecting block 163 are connected to each other to form a ring-shaped frame structure, the length of the third connecting block 163 is equal to the length of one of the sides of the connecting component 100. In this solution, the corner structure of the first body 151 and the second body 152 can be reduced, so that the material utilization rate of the mold for processing the first body 151 and the second body 152 is higher. In addition, the second connecting block 162 and the third connecting block 163 can also be located at the front appearance surface of the air handling unit 1. This solution can make the appearance surface of the connection component 100 more neat regardless of the size of the air handling unit 1 adapted to the connection component 100.

[0148] In order to improve the adaptation effect of the connecting component 100, in some embodiments, the connecting component 100 further includes a fourth connecting block 164 and a fifth connecting block 165, one end of the fourth connecting block 164 is suitable for detachably connecting to the first connecting end 1511, and the other end is suitable for detachably connecting to the third connecting end 1521, one end of the fifth connecting block 165 is suitable for detachably connecting to the second connecting end 1512, and the other end is suitable for detachably connecting to the fourth connecting end 1522, and along the circumferential direction of the third axis, the difference between the length of the fourth connecting block 164 and the length of the first connecting block 161 is equal to the difference between the length of the fifth connecting block 165 and the length of the second connecting block 162. The specific adaptation method of this solution is referred to above and will not be repeated here.

In some embodiments, the annular frame structure composed of the first body 151, the second body 152, the first connecting block 161 and the second connecting block 162 is the same structure as the annular frame structure composed of the first frame 110 and the second frame 120, and only the structural division is different.

[0150] In some embodiments, the first body 151 and the second body 152 can be divided into two parts, and the first connecting block 161 and the second connecting block 162 are both separate parts. In this way, when adapting, only two parts need to be removed or installed (when the first connecting block 161 and the second connecting block 162 are both divided into two parts, four parts need to be removed), which reduces the difficulty of disassembly and assembly.

[0151] In some embodiments, the second end 112 is provided with a first limiting groove 1121, the fourth end 122 is provided with a second limiting groove 1221, and the connecting component 100 further includes a limiting member 130, one end of the limiting member 130 extends into the first limiting groove 1121, and the other end extends into the second limiting groove 1221.
