Electric control box and air conditioner
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to Chinese patent application number 202410244188.8, filed on March 4, 2024, entitled “Electric Control Box and Air Conditioner,” the entire contents of which are incorporated herein by reference. Technical Field
[0003] The present application relates to the technical field of air conditioning, and in particular to an electric control box and an air conditioner. Background Art
[0004] In the related art, in order to facilitate maintenance, the electric control box often adopts a detachable shell structure. In order to facilitate installation and positioning, the electric control box can be designed with a connection structure and a pre-positioning structure. For example, the electric control box can be installed by screw fixing. This installation method requires positioning the screw holes before installing the screw holes. At the same time, in order to facilitate the positioning of the screw holes, a pre-positioning structure is used to align the screw holes before doing so. When the above-mentioned electric control box is repaired, only a part of the shell is removed, and then the complete electric control box is assembled after the repair is completed. The electric control box is often installed in the air conditioner after the assembly is completed. Therefore, the electric control box in the related art only has a pre-positioning structure on one of the shells. In this case, if only a part of the electric control box shell is removed during maintenance, the shell will not have the pre-positioning structure when it is reassembled, making it difficult to position the electric control box shell during reassembly after maintenance, which is inconvenient to operate.

[0054] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0055] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0056] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or", "and / or" or "and / or" appear in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
[0057] In the related art, in order to facilitate maintenance, the electric control box often adopts a detachable shell structure. In order to facilitate installation and positioning, the electric control box can be designed with a connection structure and a pre-positioning structure. For example, the electric control box can be installed by screw fixing. This installation method requires positioning the screw holes before installing the screw holes. At the same time, in order to facilitate the positioning of the screw holes, a pre-positioning structure is used to align the screw holes before doing so. When the above-mentioned electric control box is repaired, only a part of the shell is removed, and then the complete electric control box is assembled after the repair is completed. The electric control box is often installed in the air conditioner after the assembly is completed. Therefore, the electric control box in the related art only has a pre-positioning structure on one of the shells. In this case, if only a part of the electric control box shell is removed during maintenance, the shell will not have the pre-positioning structure when it is reassembled, making it difficult to position the electric control box shell during reassembly after maintenance, which is inconvenient to operate.
[0058] In view of this, referring to Figures 1 to 14, an embodiment of the present application provides an electric control box 100, which is used for an air conditioner 200. Referring to Figures 1 to 4, the air conditioner 200 includes a connecting structure 211. According to different requirements, the connecting structure 211 of the air conditioner 200 can be any structural member suitable for connection, and the connecting structure 211 can be set at any suitable position, for example, it can be set at the housing 210 of the air conditioner 200. For the setting relationship between the electric control box 100 and the connecting structure 211, please refer to the following text. The electric control box 100 includes a first box body assembly 110 and a second box body assembly 120.
[0059] Referring to Figures 5 to 7, specifically, the first box body assembly 110 includes a first shell 111 and a first positioning portion 112 connected to the first shell 111. The second box body assembly 120 includes a second shell 121 and a second positioning portion 122 connected to the second shell 121. According to different needs, in different embodiments, the first shell 111 and the first positioning portion 112 can be connected in an integral manner or welded. The first shell 111 and the first positioning portion 112 can also be connected using any suitable connection structure 211. In addition, the second shell 121 and the second positioning portion 122 are also connected in the same manner. For ease of description, the following embodiments are described in which the first shell 111 and the first positioning portion 112 are integrally connected, and the second shell 121 and the second positioning portion 122 are integrally connected. Different embodiments can be combined with each other between different technical solutions.
[0060] Referring to Figures 5-7 , the second housing 121 is detachably connected to the first housing 111, and together they form a housing cavity 130. It will be appreciated that the first housing 111 and the second housing 121 are two separate parts of the complete housing of the electrical control box 100, and when combined, the two housings together define the housing cavity 130. The housing cavity 130 can be used to house control components required by the electrical control box 100, such as circuit boards and wires.
[0061] In conjunction with the connection structure 211 of the air conditioner 200 described above, as shown in Figures 1-7 , the first positioning portion 112 and the second positioning portion 122 are adapted to be coupled to the connection structure 211 to position the electric control box 100 relative to the connection structure 211. It will be appreciated that, when the first housing 111 and the second housing 121 are assembled and coupled, the first positioning portion 112 and the second positioning portion 122 can serve as positioning members for the electric control box 100 and can cooperate with the connection structure 211 to position the electric control box 100. Furthermore, as shown in Figures 5-7 , in some embodiments, the first positioning portion 112 can be coupled to the second positioning portion 122 to facilitate their combined positioning. As shown in Figure 9 , in other embodiments, the first positioning portion 112 can be spaced apart from the second positioning portion 122. On the other hand, the first positioning portion 112 and the second positioning portion 122 can also respectively play a positioning role. Specifically, referring to Figures 1 to 7, the first positioning portion 112 is suitable for connecting to the connecting structure 211 to locate the position of the first box body assembly 110 relative to the connecting structure 211; referring to Figures 1 to 7 and Figure 14, the second box body assembly 120 is suitable for connecting to the connecting structure 211 or the first positioning portion 112 to locate the position of the second box body assembly 120 relative to the first box body assembly 110. It can be understood that the connection between the first positioning portion 112 and the connecting structure 211 can be used for positioning between the first box body assembly 110 and the connecting structure 211; the connection between the second positioning portion 122 and the connecting structure 211 (or the first positioning portion 112) can be used for positioning between the first box body assembly 110 and the second box body assembly 120. 5-7 , on the one hand, the second positioning portion 122 can achieve relative positioning between the first box assembly 110 and the second box assembly 120 by connecting with the connecting structure 211, so as to facilitate further assembly and connection of the first box assembly 110 and the second box assembly 120. Referring to FIG14 , on the other hand, the second positioning portion 122 can achieve pre-positioning of the connection between the first box assembly 110 and the second box assembly 120 by connecting with the first positioning portion 112, so as to facilitate subsequent assembly and alignment operations between the first box assembly 110 and the second box assembly 120.
[0062] In conjunction with specific scenarios of assembly and disassembly of the electric control box 100, in some embodiments, in addition to the first positioning portion 112 and the second positioning portion 122, the electric control box 100 also needs to be connected to the air conditioner 200 housing through a connector (the connector can be connected to the connection structure 211 of the air conditioner 200 or to other structures), or to connect the first box assembly 110 and the second box assembly 120. For example, the connector can be a screw. Accordingly, the electric control box 100 and the air conditioner 200 housing can both have screw holes to facilitate the installation of the electric control box 100 on the air conditioner 200 housing, and the screw holes of the first box assembly 110 correspond to the screw holes of the second box assembly 120 to facilitate the assembly and connection between the first box assembly 110 and the second box assembly 120. Based on this, the first positioning portion 112 and the second positioning portion 122 can both be used for pre-positioning, that is, to determine the approximate installation position before installing the electric control box 100 or assembling the first box assembly 110 and the second box assembly 120. When the electric control box 100 needs to be repaired, only a portion of the box body (one of the first box body assembly 110 and the second box body assembly 120) is removed, and after the repair is completed, the box body 100 is reassembled to form a complete electric control box 100. In this case, since the first positioning portion 112 and the second positioning portion 122 of the electric control box 100 of the present application can be independently connected to the connecting structure 211, even if the second box body assembly 120 is removed during repair, the first box body assembly 110 can still be positioned relative to the connecting structure 211. When the second box body assembly 120 needs to be reassembled with the first box body assembly 110 after the repair, the connection between the second positioning portion 122 and the connecting structure 211 can be used to pre-position the second box body assembly 120, so as to facilitate subsequent assembly and connection. For example, the first box body assembly 110 and the second box body assembly 120 can be further connected by screws or snaps after pre-positioning. In addition, the first positioning portion 112 and the second positioning portion 122 can respectively play a positioning effect. On the other hand, since both are suitable for being connected to the connecting structure 211, after the electric control box 100 is assembled, the first positioning portion 112 and the second positioning portion 122 can work together to achieve a better positioning effect.
[0063] The above-mentioned arrangement of the second positioning portion 122 being suitable for connecting to the connecting structure 211 or the first positioning portion 112, both of these connection methods can facilitate the reassembly connection operation between the first box body assembly 110 and the second box body assembly 120, that is, before the first box body assembly 110 and the second box body assembly 120 are assembled and spliced, pre-positioning can be achieved by connecting the second positioning portion 122 to the connecting structure 211, or by connecting the second positioning portion 122 to the first positioning portion 112, and both connection methods can be used simultaneously. For ease of description, the following is an embodiment in which the second positioning portion 122 is suitable for connecting to the connecting structure 211 to achieve pre-positioning between the second box body assembly 120 and the first box body assembly 110 as an example for explanation, and different embodiments can be combined with each other between different technical solutions.
[0064] Based on the combination of the above embodiments, it can be seen that the electric control box 100 of the present application solution includes a first box body assembly 110 and a second box body assembly 120. The first box body assembly 110 includes a first shell 111 and a first positioning portion 112 connected to the first shell 111; the second box body assembly 120 includes a second shell 121 and a second positioning portion 122 connected to the second shell 121. The second shell 121 is detachably connected to the first shell 111, and the second shell 121 and the first shell 111 together form a receiving cavity 130. The first positioning portion 112 and the second positioning portion 122 are adapted to be jointly connected to the connecting structure 211 to position the electric control box 100 relative to the connecting structure 211. The first positioning portion 112 is adapted to be connected to the connecting structure 211 to position the first box body assembly 110 relative to the connecting structure 211. The second box body assembly 120 is adapted to be connected to the connecting structure 211 to position the second box body assembly 120 relative to the first box body assembly 110. Compared to related art designs where only a portion of the box body has a positioning structure, the present invention's electrical control box 100 has positioning structures on both disassembled parts, namely, the first positioning portion 112 and the second positioning portion 122. Therefore, when the present invention's electrical control box 100 is reassembled after repair, the disassembled box body assembly still retains its positioning capability, facilitating the repositioning and reassembly of the two parts. Therefore, the present invention's electrical control box 100 facilitates positioning operations during disassembly and repair, improving assembly position accuracy.
[0065] In addition, regarding the specific manner in which the first positioning portion 112 and the second positioning portion 122 of the present application scheme are jointly connected to the connecting structure 211, in some embodiments, the first positioning portion 112 and the second positioning portion 122 can be simultaneously connected to the connecting structure 211 to jointly play a role in positioning the electrical control box 100, thereby simplifying the positioning operation and reducing the complexity of the structure.
[0066] Specifically, regarding the specific structural forms of the first positioning portion 112 and the second positioning portion 122, referring to Figures 5-7, in one embodiment of the positioning portion structure, the first positioning portion 112 may have a first opening 1121, and the second positioning portion 122 may have a second opening 1221. The first opening 1121 and the second opening 1221 may both extend along the first direction X. Based on this, when viewed along the first direction X, the first opening 1121 and the second opening 1221 may at least partially overlap, allowing for simultaneous insertion into the connecting structure 211. It is understood that to accommodate the openings, the connecting structure 211 may be an overhanging structure. Since the first opening 1121 and the second opening 1221 extend in the same direction and at least partially overlap, the connecting structure 211 can be simultaneously inserted into the first opening 1121 and the second opening 1221. This positioning operation allows the electric control box 100 with the openings to be directly hung on the overhanging connecting structure 211. Furthermore, since separation of the first and second housing assemblies 110 and 120 does not affect the positioning of the other, in some embodiments, the first opening 1121 and the second opening 1221 may be spaced apart. In other embodiments, the planes of the first and second openings 1121 and 1221 may be aligned with each other, and the first positioning portion 112 and the second positioning portion 122 may be connected, so that the first and second openings 1121 and 1221 are combined into one opening.
[0067] Referring to Figure 10, in another embodiment of the positioning portion structure, the first positioning portion 112 can have a first protrusion 1122, and the second positioning portion 122 can have a second protrusion 1222. Based on this, the first protrusion 1122 and the second protrusion 1222 can be spliced with each other so as to be suitable for being simultaneously inserted into the connecting structure 211. It can be understood that the positioning method of this type of embodiment is similar to that of the previous type of embodiment, the difference being that the protrusion structure and the opening structure are interchanged, and the first protrusion 1122 and the second protrusion 1222 can be combined and spliced, and after the two are separated, they can form two independent protrusion structures. In some embodiments, a detachable connecting structure 211 can be provided between the first protrusion 1122 and the second protrusion 1222; in other embodiments, the first protrusion 1122 and the second protrusion 1222 can abut against each other solely by relying on the connection between the first shell 111 and the second shell 121. In embodiments where the first positioning portion 112 and the second positioning portion 122 are protruding structures, the corresponding connecting structure 211 can also be a protruding structure or an open-hole structure. Furthermore, in this type of embodiment, because the first protrusion 1122 and the second protrusion 1222 can be spliced together and connected to the connecting structure 211, when the two act together, the connecting force exerted by the connecting structure 211 on the electric control box 100 is more concentrated and stable, thereby achieving a better supporting and positioning effect.
[0068] Regarding the specific form of the connection between the first housing 111 and the second housing 121, referring to Figures 7-8 , in some embodiments, the first housing 111 may have a first mating surface 1111, the first positioning portion 112 may have a second mating surface 1123, and the first mating surface 1111 may be coplanar with the second mating surface 1123. Similarly, referring to Figures 7-8 , in some embodiments, the second housing 121 may have a third mating surface 1211, the second positioning portion 122 may have a fourth mating surface 1223, and the third mating surface 1211 may be coplanar with the fourth mating surface 1223. It is understood that, in order to achieve a splicing effect, the first splicing surface 1111 should be the end surface of the first shell 111, and the first positioning portion 112 is also located at the end, and is located at the same end as the first splicing surface 1111, so that the first splicing surface 1111 and the second splicing surface 1123 are coplanar, and the third splicing surface 1211 and the fourth splicing surface 1223 are arranged in the same manner. Based on the above arrangement, referring to Figures 7-9, in some embodiments, the first splicing surface 1111 can be spliced with the third splicing surface 1211, and the second splicing surface 1123 can be spliced with the fourth splicing surface 1223. It is understood that, on the one hand, the first shell 111 and the second shell 121 can be spliced together by relying on the connection between the first splicing surface 1111 and the third splicing surface 1211, and the first positioning portion 112 and the second positioning portion 122 can be spliced together by relying on the connection between the second splicing surface 1123 and the fourth splicing surface 1223. Furthermore, when the first shell 111 and the second shell 121 are spliced together, the first positioning portion 112 and the second positioning portion 122 can also be spliced together at the same time. This arrangement makes the splicing between the first positioning portion 112 and the second positioning portion 122 more convenient and simplifies the operation.
[0069] With reference to the description of the above embodiments, in some embodiments, the first positioning portion 112 and the second positioning portion 122 can both serve as pre-positioning structures for the electric control box 100, while the electric control box 100 still needs to be connected to the housing of the air conditioner 200 via a connector. Specifically, referring to FIG. 6 , in some embodiments, the first housing assembly 110 can have a third opening 114, and the second housing assembly 120 can have a fourth opening 124. Accordingly, the electric control box 100 can further include screws. The screws can be inserted through the third opening 114 and the fourth opening 124 to connect the first housing assembly 110 and the second housing assembly 120. It is understood that the third opening 114 and the fourth opening 124 can be concentrically arranged, so that they can both serve as connecting holes for connecting the first housing assembly 110 and the second housing assembly 120, or as connecting holes for connecting the electric control box 100 as a whole to the housing 210 of the air conditioner 200 (or other structures of the air conditioner 200). In combination with the description of the above embodiments, when the second box body assembly 120 needs to be reassembled after being disassembled for inspection, the second positioning portion 122 can be connected to the connecting structure 211 before tightening the screws to complete the pre-positioning of the second box body assembly 120 relative to the first box body assembly 110, and then the first box body assembly 110 and the second box body assembly 120 can be connected using screws.
[0070] In addition to relying on screw connections, in some embodiments, the connection between the first box body assembly 110 and the second box body assembly 120, or the connection between the electric control box 100 and the housing 210 of the air conditioner 200 (or other structures of the air conditioner 200), can also be connected using snap-fit connections. The above arrangement helps to make the system structure of the electric control box 100 tight and not easy to loosen, thereby facilitating the assembly of the box body components of the electric control box 100 or the assembly of the electric control box 100 as a whole.
[0071] Based on the arrangement of the various joining surfaces in the above embodiments, as shown in Figures 5-8 , in some embodiments, the first housing assembly 110 may further include a first reinforcing rib 113, and the second housing assembly 120 may further include a second reinforcing rib 123. The first joining surface 1111 and the third joining surface 1211 may be joined together along the first direction X, and the second joining surface 1123 and the fourth joining surface 1223 may be joined together along the first direction X. The following definition of the joining of the first joining surface 1111 and the third joining surface 1211 along the first direction X is given as follows: the abutting force generated by the joining of the first joining surface 1111 and the second joining surface 1123 is parallel to the first direction X, meaning that the first joining surface 1111 and the second joining surface 1123 may be joined together by applying a force along the first direction X. The definition of the joining of the second joining surface 1123 and the fourth joining surface 1223 along the first direction X is similar.
[0072] Based on this, referring to Figures 5-8 , in some embodiments, along the first direction X, the first reinforcing rib 113 may be located on a side of the first mating surface 1111 away from the third mating surface 1211 and on a side of the second mating surface 1123 away from the fourth mating surface 1223. It is understood that, along the first direction X, one side of the first housing assembly 110 (i.e., the side where the first mating surface 1111 and the second mating surface 1123 are located) may be used for mating with the second housing assembly 120, while the other opposite side may be provided with the first reinforcing rib 113, which may extend toward a side away from the first mating surface 1111 and the second mating surface 1123. Similarly, the second reinforcing rib 123 may be located on a side of the third mating surface 1211 away from the first mating surface 1111 and on a side of the fourth mating surface 1223 away from the second mating surface 1123. The above arrangement enables the first reinforcing rib 113 and the second reinforcing rib 123 to be located on opposite sides of their corresponding splicing surfaces, thereby improving the connection strength between the first box body assembly 110 and the second box body assembly 120 .
[0073] In addition, further arrangements may be made for the extension directions of the first reinforcing rib 113 and the second reinforcing rib 123. Referring to Figures 5-8, in some embodiments, the first reinforcing rib 113 may connect the first shell 111 and the first positioning portion 112. The first shell 111 may have a first surface 1112. The first positioning portion 112 may connect the first surface 1112. The first reinforcing rib 113 may include a first portion 1131 and a second portion 1132 that are connected to each other. Based on this, the first surface 1112 and the first portion 1131 may both extend along a first direction X, and the first positioning portion 112 and the second portion 1132 may both extend along a second direction Y that is perpendicular to the first direction X. It can be understood that the first part 1131 and the second part 1132 of the first reinforcing rib 113 can be connected to the first positioning portion 112 and the second positioning portion 122 respectively, and the extension directions of the first part 1131 and the second part 1132 are perpendicular to each other, that is, the first reinforcing rib 113 is in an "L" shape. The above arrangement can improve the connection reliability of the first positioning portion 112 and improve the overall rigidity and strength of the electrical control box 100.
[0074] Similar to the above embodiment, referring to Figures 5-8 , in some embodiments, the second housing assembly 120 may further include a second reinforcing rib 123. The second reinforcing rib 123 may connect the second housing 121 and the second positioning portion 122. The second housing 121 may have a second surface 1212. The second positioning portion 122 may connect the second surface 1212. The second reinforcing rib 123 may include a third portion 1231 and a fourth portion 1232 that are interconnected. The second surface 1212 and the third portion 1231 may both extend along a first direction X, and the second positioning portion 122 and the fourth portion 1232 may both extend along a second direction Y perpendicular to the first direction X. It will be appreciated that the configuration of this embodiment is similar to the previous embodiment, except that the configuration of the first housing assembly 110 and the first reinforcing rib 113 is also applied to the second housing assembly 120 and the second reinforcing rib 123. The simultaneous application of these two embodiments can provide the electric control box 100 with improved rigidity and strength.
[0075] To further facilitate positioning of the electrical control box 100, referring to FIG. 7 and FIG. 4 , in some embodiments, the electrical control box 100 may further include an insert 140 and a screw 150. The insert 140 and screw 150 may connect the first housing assembly 110 and / or the second housing assembly 120. It is understood that the insert 140 and screw 150 may be independently located in the first housing assembly 110 or the second housing assembly 120, or may be connected to the first housing assembly 110 and the second housing assembly 120, respectively (the two inserts 140 and screw 150 connecting the two housing assemblies may be separated or spliced together). Accordingly, the insert 140 and screw 150 may be adapted to extend into the insertion hole 212 of the air conditioner 200 to position the electrical control box 100 relative to the insertion hole 212. The insertion hole 212 of the air conditioner 200 may be any opening structure suitable for plug-in installation. Therefore, the engagement between the screw 150 of the insert 140 and the insertion hole 212 allows further positioning of the electric control box 100 through insertion. Regarding the specific engagement mechanism of the screw 150 of the insert 140, in some embodiments, the first box assembly 110 and the second box assembly 120 may be positioned relative to each other along a first direction X. Based on this, along a second direction Y perpendicular to the first direction X, the first positioning portion 112 and the second positioning portion 122 may both be located at one end of the electric control box 100, while the screw 150 of the insert 140 may be located at the other end of the electric control box 100. It is understood that, along the second direction Y, one end of the electric control box 100 can be positioned by the engagement between the first positioning portion 112 and the second positioning portion 122 and the connecting structure 211, while the other end of the electric control box 100 can be positioned by the engagement between the screw 150 of the insert 140 and the insertion hole 212. This allows positioning structures to be present on both sides of the electric control box 100, improving positioning accuracy. In conjunction with the arrangement of the first opening 1121 and the second opening 1221 in the above embodiment, during the specific positioning and installation process of the electric control box 100, the first positioning portion 112 and the second positioning portion 122 can be connected to the connecting structure 211, and the screw 150 of the insert 140 can be inserted into the insert hole 212. This completes the pre-positioning operation of the electric control box 100, and the electric control box 100 can then be fixed and installed using the connecting member. For example, in some embodiments, the first direction X can correspond to the horizontal direction, and the second direction Y can correspond to the vertical direction. Thus, the electric control box 100 with the first opening 1121 and the second opening 1221 can be hung on the raised connecting structure 211 by gravity, and the screw 150 of the insert 140 can be inserted into the insert hole 212 along the second direction Y, making the fit between the two more secure.
[0076] Corresponding to different forms of insertion holes 212, the insertion member 140 screw 150 can be correspondingly set into different structural forms. Based on the definitions of the insertion member 140 screw 150 in the above embodiments and the relative arrangement of the first box body assembly 110 and the second box body assembly 120 along the first direction X, referring to Figure 4, in some embodiments, the insertion hole 212 can include a fifth part and a sixth part that are connected to each other, and the insertion member 140 screw 150 can include a seventh part and an eighth part that are connected to each other. Thus, the fifth part and the seventh part can both extend along the second direction Y perpendicular to the first direction X, and the sixth part and the eighth part can both extend along a direction that intersects the first direction X and the second direction Y. In addition, in some embodiments, along the second direction Y, the fifth part can be located at the upper end of the sixth part, and the seventh part can be located at the upper end of the eighth part. It can be understood that the insert 140 screw 150 and the insert hole 212 both include two sections. The seventh part of the insert 140 screw 150 corresponds to the fifth part extending into the insert hole 212, and the eighth part of the insert 140 screw 150 corresponds to the sixth part extending into the insert hole 212. In order to achieve a better insert positioning effect, while the insert 140 screw 150 can extend into the insert hole 212 along the second direction Y, the extension direction of the sixth part and the eighth part is at a certain angle to the second direction Y and the first direction X, which plays a guiding and card-jointing positioning effect, making the connection more secure.
[0077] The electrical control box 100 can also be used to form a heat dissipation airflow channel. Referring to Figures 1-4, in some embodiments, the electrical control box 100 may have a third surface 160. In different embodiments, the third surface 160 may be a wall surface of the first box body assembly 110 or the second box body assembly 120, or a wall surface of other structures of the electrical control box 100. The third surface 160 may have a supporting protrusion 161. The supporting protrusion 161 may be adapted to contact the supporting surface 213 of the air conditioner 200. The supporting surface 213 of the air conditioner 200 can be understood as a wall surface adapted to support the electrical control box 100, and it may take any suitable form, such as a curved surface or a flat surface. Thus, the supporting protrusion 161 may be adapted to abut the supporting surface 213, thereby forming a gap 220 between the third surface 160 and the supporting surface 213, which is adapted to guide the heat dissipation airflow. It is understandable that the support protrusion 161 can support the electric control box 100 and lift the electric control box 100, so that a gap 220 is formed between the third surface 160 and the support surface 213. The gap 220 defined above is conducive to heat dissipation of the electric control box 100.
[0078] Referring to Figures 1-10 , in some embodiments, the electrical control box 100 may further include a heat sink 170. Heat sink 170 may be a component for dissipating heat and may be made of metal or plastic. In some embodiments, to achieve better heat dissipation, the heat sink 170 may be connected to the second housing assembly 120, corresponding to the placement of the second housing assembly 120 outside the first housing assembly 110. Heat sink 170 and third surface 160 may both be located at the lower end of the electrical control box 100. The lower end of the electrical control box 100 is defined as follows: the electrical control box 100 has a center point. Along the second direction Y (assuming the second direction Y is the vertical direction), the midpoint between the uppermost and lowermost endpoints of the electrical control box 100 is the center point of the electrical control box 100. A plane passing through the center point and perpendicular to the second direction Y is the boundary plane. The portion of the electrical control box 100 below the boundary plane is the lower end of the electrical control box 100, and the portion above the boundary plane is the upper end of the electrical control box 100. Defining the aforementioned gap 220 increases the distance between the electrical control box 100 and the support surface 213, facilitating air circulation and improving heat dissipation.
[0079] Based on the above configuration, referring to FIG4 , in some embodiments, the gap 220 can communicate with the accommodating cavity 130. In some embodiments, the portion of the accommodating cavity 130 used to accommodate components can communicate with the gap 220; in other embodiments, the accommodating cavity 130 can be separated into a separate cavity for heat dissipation. It is understood that the gap 220 can be used to guide heat dissipation airflow and redirect it back into the accommodating cavity 130. Thus, the electrical control box 100 can have an opening connecting the accommodating cavity 130 and the gap 220 to achieve the above-mentioned effect. Combined with the arrangement of the heat sink 170, the gap 220 and the accommodating cavity 130, in some embodiments, since the heat sink 170 and the gap 220 are both located at the lower end of the electrical control box 100, the heat dissipation airflow can pass through the accommodating cavity 130 from the lower end of the electrical control box 100, and the position where the heat dissipation airflow enters the accommodating cavity 130 is closer to the heat sink 170, so that the heat dissipation effect is better. Moreover, since the heat in the electrical control box 100 is more likely to accumulate at the upper end, the above arrangement enables the heat dissipation airflow to flow from bottom to top along the accommodating cavity 130, and is not easily affected by the heat of the electrical control box 100 itself, resulting in a better heat dissipation effect.
[0080] To improve heat dissipation, referring to FIG11 , in some embodiments, the electrical control box 100 may include a fourth surface 180 , which may include a first heat dissipation vent 181 . It is understood that the first heat dissipation vent 181 can be used to dissipate heat within the electrical control box 100 . Combined with the arrangement of the gap 220 and the accommodating cavity 130 in the above-described embodiment, the first heat dissipation vent 181 , the accommodating cavity 130 , and the gap 220 can be interconnected, thereby allowing the first heat dissipation vent 181 to serve as an outlet for the heat dissipation airflow. Based on this, referring to FIG11 , in some embodiments, the electrical control box 100 may further include a cover 190 , which may cover the heat dissipation vent. Because components within the electrical control box 100 are prone to ignition and sparks can easily escape directly from the first heat dissipation vent, the aforementioned arrangement of the cover 190 can serve as a fireproofing measure by shielding sparks to prevent them from escaping. Furthermore, to ensure effective heat dissipation, referring to FIG. 11 , in some embodiments, the cover 190 may include a second heat dissipation port 191 connected to the first heat dissipation port 181, and the opening directions of the first heat dissipation port 181 and the second heat dissipation port 191 may intersect. It is understood that since the opening directions of the two heat dissipation ports intersect, sparks emitted from the first heat dissipation port 181 are prevented from further escaping from the second heat dissipation port 191. The presence of the second heat dissipation port 191 also ensures that the first heat dissipation port 181 can be connected to the outside world, thereby reducing the impact of the cover 190 on the heat dissipation effect. To improve the heat dissipation effect, in some embodiments, the second heat dissipation port 191 may be as close as possible to the first heat dissipation port 181, and the two heat dissipation ports are respectively provided on two perpendicular walls, so that the side of the cover 190 can be used for heat dissipation, while the front can be used for fire protection.
[0081] Regarding the connection of the electric control board of the electric control box 100, referring to Figures 12-13, in some embodiments, the inner peripheral wall defining the accommodating cavity 130 may have a slot 115 and a snap 116. Furthermore, the inner peripheral wall may have at least two slots 115 or snap 116 on each side in the horizontal direction. For example, one side may have two slots 115 and the other side may have two snap 116. The electric control board of the electric control box 100 may be connected to the slots 115 and snap 116. This arrangement prevents uneven force on the electric control board after insertion, which may cause it to become loose, thereby ensuring the reliability of the electric control board assembly.
[0082] Regarding the setting of the wire groove 117 of the electric control box 100, see Figures 12 and 13. In some embodiments, the inner wall of the electric control box 100 can be provided with a wire groove 117. A baffle can be provided between the wire groove 117 and the electric control board to separate the wire body from the electric control board and improve the safety of wiring. A wire hook and a wire outlet hole 118 can be provided above the inner wall to facilitate leading the wires out of the accommodating cavity 130 of the electric control box 100. Referring to Figures 12 and 13, in some embodiments, the wire outlet hole 118 is a vertically staggered structure. Specifically, the above-mentioned vertically staggered structure can indicate that the height dimension of the wire outlet hole 118 gradually decreases along the extension direction of the wire outlet hole 118. For example, the outlet holes 118 can be configured with a height difference (d) of ≥4mm, with the wires exiting the electrical control box 100 from the inside and exiting downward. This creates a height difference in the outlet holes 118, preventing condensation from the air conditioner 200 from flowing back into the electrical control box 100 along the wires, thereby improving wiring safety. Furthermore, the number of top outlet holes 118 can be no less than two, allowing for separate outlets for high-voltage and low-voltage wires, achieving strong and low-voltage separation.
[0083] To further improve the strength and rigidity of the electric control box 100 , in some embodiments, a plurality of external support ribs may be provided at intervals on the inner peripheral wall of the electric control box 100 .
[0084] Referring to Figures 1-4 , an embodiment of the second aspect of the present application further provides an air conditioner 200, comprising an electric control box 100 according to any of the above-described embodiments, a housing 210, and a thermal management system. Housing 210 houses electric control box 100, and the thermal management system can be a cooling system or a heating system of air conditioner 200. The thermal management system and other structures of air conditioner 200 can be referenced in related art and will not be further described here.
[0085] In combination with the description of the above embodiments, the connection structure 211, the insertion hole 212 and the support surface 213 of the air conditioner 200 can all be provided on the housing 210, and the above structures can match the corresponding structures of the electric control box 100. For example, referring to Figures 1 to 4, in some embodiments, the connection structure 211 can be a hook, and correspondingly, the electric control box 100 can be hung on the hook using the first opening 1121 and the second opening 1221; the extension direction of the insertion hole 212 can be the same as the extension direction of the screw 150 of the insert 140 to facilitate the insertion and matching of the two; the support surface 213 can be the bottom surface of the housing 210, that is, a platform structure can be provided at the screw installation position below the electric control box 100 to facilitate the positioning and installation of the electric control box 100 and to facilitate the support of the electric control box 100.
[0086] Furthermore, to further enhance the reliability of the installation of the electrical control box 100, as shown in Figures 1-4 , in some embodiments, support blocks or support ribs may be provided on the upper volute portion and the middle partition portion of the connecting structure 211 of the electrical control box 100, thereby increasing the strength and rigidity of the electrical control box 100 and the connecting structure 211. Specifically, in some embodiments, the electrical control box 100 is suspended from the connecting structure 211, and a wall surface of the connecting structure 211 extending along the second direction Y is subjected to tensile stress along the second direction Y, while the support blocks or support ribs may be connected to another wall surface of the connecting structure 211 extending along the first direction X.
[0087] Referring to Figures 1-4 , in some embodiments, the chassis of the air conditioner 200 and the structures connected to it (e.g., wires) are lower than the lowest height of the control box 100 around the installation location of the control box 100. Furthermore, a wire tie is provided on the chassis at the front of the control box 100 to facilitate wiring. This arrangement, particularly the installation of the cover of the control box 100, prevents the chassis from being bumped and causing jams during installation.
[0088] Thanks to the improvements made to the electric control box 100 in the above embodiments, the air conditioner 200 according to the second embodiment of the present application has the same technical effects as the electric control box 100 in the above embodiments, which will not be described in detail here.
[0089] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present application.
