Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to an embedded air conditioning indoor unit and an embedded air conditioner. Background Technology

[0002] In existing embedded air conditioner indoor units, the enclosure needs to be connected to both the chassis and the electrical control box, resulting in multiple connection structures on the enclosure. Because these connection structures differ in function and installation requirements, but are quite similar in appearance and layout, installers are prone to confusion during actual operation, increasing installation difficulty and the probability of errors.

[0003] For example, the screw holes on the enclosure for fixing the chassis and those for fixing the electrical control box are densely distributed, making it difficult for installers to quickly and accurately distinguish the specific purpose of these screw holes during assembly. This can lead to incorrect installation of the electrical control box, resulting in rework and quality issues, severely impacting production efficiency and product quality. Furthermore, this chaotic connection structure layout also greatly inconveniences subsequent maintenance and repair work, increasing maintenance costs and time.

[0004] Therefore, the efficiency and accuracy of the current electrical control box installation process still need to be improved.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0041] Unless otherwise stated, the term "multiple" means two or more.

[0042] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0043] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0045] Combination Figure 1-5 As shown in the figure, this disclosure provides an embedded air conditioner indoor unit, including a housing 30 and an electrical control box 20.

[0046] like Figure 5 As shown, the housing 30 includes a chassis 307 and a surrounding plate 10. The connection between the surrounding plate 10 and the chassis 307 is bent. The surrounding plate 10 is arranged along the circumference of the chassis 307 and together with the chassis 307, it encloses the installation space. The indoor heat exchanger and fan of the indoor unit are both located within the installation space.

[0047] The enclosure 10 is provided with a first connecting structure 101, and the chassis 307 is provided with a first connecting and mating structure. The first connecting and mating structure is connected to the first connecting structure 101 to realize the connection between the enclosure 10 and the chassis 307.

[0048] like Figures 1 to 3 As shown, the enclosure 10 is also provided with a second connecting structure 102, and the electrical control box 20 is provided with a second connecting and mating structure 201. The second connecting and mating structure 201 is connected to the second connecting structure 102 to realize the connection between the enclosure 10 and the electrical control box 20.

[0049] The housing 30 is provided with an indicator 105 to distinguish the first connection structure 101 and the second connection structure 102.

[0050] Setting an indicator mark 105 on the housing 30 to distinguish the first connection structure 101 and the second connection structure 102 can effectively avoid installation errors caused by incorrect use of the first connection structure 101 and the second connection structure 102 during the installation process, improve installation efficiency and accuracy, reduce rework and quality accidents, and enhance the overall quality and reliability of the product.

[0051] The indicator sign 105 can be installed on the enclosure 10, on the chassis 307, or both the enclosure 10 and the chassis 307 can have the indicator sign 105 installed.

[0052] Optionally, the indicator 105 may include text, numbers, colors, and / or graphics.

[0053] Text, numbers, and / or graphics make the indicator 105 more intuitive and clear, making it easier for installers to quickly and accurately identify and distinguish the first connection structure 101 and the second connection structure 102, further improving installation efficiency and accuracy.

[0054] For example, the indicator 105 may be in text form, displaying phrases such as "for connection to chassis 307" at the first connection structure 101, and / or "for connection to electrical control box 20" at the second connection structure 102; or, for another example, the indicator 105 may be in numerical form, displaying "1" at the first connection structure 101 and on chassis 307, and / or "2" at the second connection structure 102 and on electrical control box 20. For yet another example... Figure 1 An arrow is marked at the first connecting structure 101, but no arrow is marked at the second connecting structure 102.

[0055] The indicator 105 can also be in other forms, as long as it can distinguish the first connection structure 101 and the second connection structure 102.

[0056] Optionally, such as Figure 1 As shown, there are multiple first connection structures 101 and multiple second connection structures 102. At least one second connection structure 102 is disposed between two adjacent first connection structures 101, or at least one second connection structure 102 is disposed between two adjacent second connection structures 102.

[0057] This layout makes the positions of the first connecting structure 101 and the second connecting structure 102 more reasonable and compact. At the same time, the arrangement of multiple first connecting structures 101 and second connecting structures 102 also enhances the connection strength and stability between the electrical control box 20 and the housing 30, and between the enclosure 10 and the chassis 307, further improving the safety and reliability of the product.

[0058] The number of first connecting structures can be the same as or different from the number of first connecting structures 101. When they are the same, they correspond one-to-one; when they are different, since any first connecting structure 101 can be connected to a first connecting structure, the enclosure 10 of different sizes and shapes can be connected to the chassis 307.

[0059] The number of second connecting structures 201 and the number of second connecting structures 102 can be the same or different. When they are the same, they correspond one-to-one; when they are different, since any second connecting structure 102 can be connected to a second connecting structure 201, electrical control boxes 20 of different sizes and shapes can be connected to the enclosure 10.

[0060] Optionally, the first connecting structure 101 is screwed to the first connecting mating structure; the second connecting structure 102 is screwed to the second connecting mating structure 201.

[0061] Screw connections are a common and reliable method of connection, offering advantages such as high connection strength, good stability, and ease of disassembly and maintenance. This method ensures a secure connection between the electrical control box 20 and the housing 30, and between the enclosure 10 and the chassis 307.

[0062] Optionally, such as Figure 2 As shown, the electrical control box 20 is provided with a clearance part 202 for avoiding the first connection structure 101.

[0063] The electrical control box 20 is provided with a clearance part 202 for avoiding the first connecting structure 101, which can effectively avoid interference between the electrical control box 20 and the first connecting structure 101, ensuring that the electrical control box 20 can be smoothly assembled with the housing 30, and the chassis 307 can also be smoothly assembled with the enclosure 10.

[0064] Optionally, the avoidance part 202 includes an avoidance bump 203 formed by protruding from the surface of the electrical control box 20 facing the enclosure 10 in a direction away from the enclosure 10.

[0065] The avoidance protrusion 203 does not penetrate the outer shell of the electrical control box 20. For example, the avoidance protrusion 203 is formed by the surface of the electrical control box 20 facing the enclosure 10 and corresponding to the first connecting structure 101, which protrudes in a direction away from the enclosure 10. It is not a through hole that penetrates the outer shell of the electrical control box 20. This can prevent the wire harness inside the electrical control box 20 from touching the first connecting structure 101.

[0066] When the first connection structure 101 and the first connection mating structure are connected by screws, the screw portion is located inside the avoidance protrusion 203 to prevent the screw from penetrating into the electrical control box 20 and touching the wiring harness inside the electrical control box 20.

[0067] Optionally, such as Figures 1 to 4 As shown, the enclosure 10 is provided with a third connecting structure 103, and the electrical control box 20 is provided with a third connecting and mating structure 204. The third connecting structure 103 is connected to the third connecting and mating structure 204, and the third connecting structure 103 and the third connecting and mating structure 204 are engaged.

[0068] A third connecting structure 103 is provided on the enclosure 10, and a third connecting mating structure 204 is provided on the electrical control box 20, and the two are interlocked, further enhancing the connection strength and stability between the electrical control box 20 and the housing 30. Interlocking connection is a quick and convenient connection method, enabling rapid assembly and disassembly of components without the use of tools, improving product installation efficiency and maintenance convenience. At the same time, interlocking connection effectively prevents problems such as the electrical control box 20 falling off due to loose screws, further enhancing product safety and reliability, and providing strong support for the long-term stable operation of the product.

[0069] The first connecting structure 101 and the second connecting structure 102 are located at the same end of the enclosure 10, and the third connecting structure 103 is located at the other end of the enclosure 10. That is, the second connecting structure 102 and the second connecting structure 103 are located at different ends of the enclosure 10, so that the electrical control box 20 can be well fixed on the housing 30 at all points.

[0070] Optionally, such as Figure 2 and Figure 4 As shown, one of the third connection structure 103 and the third connection mating structure 204 includes a buckle 205, and the other includes a slot 104 adapted to the buckle 205; wherein the buckle 205 protrudes from the electrical control box 20 or the enclosure 10 where it is located.

[0071] When the buckle 205 is located on the electrical control box 20, the slot 104 is located on the enclosure 10. At this time, the buckle 205 protrudes from the electrical control box 20, that is, the buckle 205 protrudes from the surface of the electrical control box 20 facing the enclosure 10. When the buckle 205 is located on the enclosure 10, the slot 104 is located on the electrical control box 20. At this time, the buckle 205 protrudes from the enclosure 10, that is, the buckle 205 protrudes from the surface of the enclosure 10 facing the electrical control box 20.

[0072] The clip 205 protrudes from the electrical control box 20 or the enclosure 10 it is located in. The protrusion of the clip 205 is designed to form a pre-deformation. Without pre-deformation, the force of a drop impact on the electrical control box 20 would be applied to the surface where the clip 205 is located, causing the surface to deform. Pre-deformation, on the other hand, pre-deforms the surface where the clip 205 is located, thus preventing further deformation and increasing the strength of the clip 205.

[0073] A notch 210 is formed at the connection between the buckle 205 and the electrical control box 20 or the enclosure 10, so that the first end 206 of the buckle 205 is connected to the electrical control box 20 or the enclosure 10. A notch 210 is formed at the second end 207 of the buckle 205, so that the second end 207 becomes a free end. The free end is inserted into the slot 104 to form a snap-fit.

[0074] Taking the buckle 205 located in the electrical control box 20 as an example, the first end 206 of the buckle 205 is connected to the electrical control box 20, and a notch 210 is formed at the second end 207 of the buckle 205.

[0075] Optionally, such as Figure 4 As shown, the buckle 205 is provided with reinforcing ribs 208 and / or the buckle 205 is provided with guide slopes 209.

[0076] The reinforcing rib 208 can effectively enhance the strength and rigidity of the buckle 205, improve the load-bearing capacity and deformation resistance of the buckle 205, thereby further enhancing the connection strength and stability between the electrical control box 20 and the housing 30, ensuring that the buckle 205 will not deform or be damaged during the product's exposure to large impacts or long-term use, and extending the product's service life.

[0077] The reinforcing rib 208 extends in the direction from the first end 206 to the second end 207, or the reinforcing rib 208 extends in the direction perpendicular to the line connecting the first end 206 and the second end 207.

[0078] The guide slope 209 facilitates the engagement between the buckle 205 and the slot 104, reduces the assembly difficulty of inserting the buckle 205 into the slot 104, improves assembly efficiency, and also helps to reduce wear on the buckle 205 and the slot 104 during assembly, further improving the quality and reliability of the product.

[0079] The guide slope 209 is located at the second end 207. Along the direction in which the buckle 205 is inserted into the slot 104, the guide slope 209 is inclined in the direction away from the electrical control box 20 or the enclosure 10 where the buckle 205 is located.

[0080] A second aspect of this utility model provides an embedded air conditioner, comprising: an embedded air conditioner indoor unit as described in any of the above embodiments.

[0081] The embedded air conditioner provided in the second aspect of this utility model includes an embedded air conditioner indoor unit as described in any of the above embodiments, and therefore has all the beneficial effects of the embedded air conditioner indoor unit as described in any of the above embodiments, which will not be repeated here.

[0082] like Figures 6 to 10As shown, the housing 30 is provided with a first connecting part 303; the electrical control box 20 is provided on the housing 30 and is provided with a second connecting part 308 that can cooperate with the first connecting part 303. The first connecting part 303 can move relative to the second connecting part 308 between a locked position and a separated position. In the locked position, the first connecting part 303 and the second connecting part 308 cooperate, and in the separated position, the first connecting part 303 and the second connecting part 308 separate.

[0083] When the electrical control box 20 is fixed to the housing 30, the first connecting part 303 and the second connecting part 308 cooperate, which does not affect the positioning between the electrical control box 20 and the housing 30. When the electrical control box 20 needs to be removed from the housing 30, the first connecting part 303 moves to the separation position relative to the second connecting part 308, and the first connecting part 303 and the second connecting part 308 separate, which does not affect the disassembly of the electrical control box 20 and the housing 30. Moreover, when the first connecting part 303 has not moved to the separation position relative to the second connecting part 308, the first connecting part 303 and the second connecting part 308 are in a locked position, so that there is still an interaction force between the electrical control box 20 and the housing 30. In this way, the electrical control box 20 will not fall off the housing 30, thereby improving the safety of disassembling the electrical control box 20.

[0084] Optionally, such as Figure 9 As shown, the first connecting part 303 and the second connecting part 308 are slidably connected.

[0085] The first connecting part 303 slides relative to the second connecting part 308, so that the two (the first connecting part 303 and the second connecting part 308) can be quickly and easily switched between the separated position and the locked position, which facilitates the installation and disassembly of the electrical control box 20.

[0086] It is understood that the first connecting part 303 and the second connecting part 308 can also adopt connection methods other than sliding connection. For example, the first connecting part 303 and the second connecting part 308 can be connected by a snap-fit ​​structure 205. The snap-fit ​​structure 205 typically includes an elastic claw 214 and a corresponding slot 104. The claw 214 can elastically deform to insert into or disengage from the slot 104. Alternatively, the first connecting part 303 and the second connecting part 308 can be connected by a magnetic material. For example, the first connecting part 303 can be a magnet, and the second connecting part 308 can be an iron component or another magnet, with both attracting and fixing each other through magnetic force. Another example is that the first connecting part 303 and the second connecting part 308 can be connected by a rotating structure. For example, the first connecting part 303 can be a threaded rotating component, and the second connecting part 308 can be a corresponding threaded hole, with connection and separation achieved through rotational movement.

[0087] Optionally, such as Figure 9As shown, one of the first connecting part 303 and the second connecting part 308 includes a claw 214 and the other includes a locking hole 304. For example, the first connecting part 303 includes a claw 214 and the second connecting part 308 includes a locking hole 304, or the first connecting part 303 includes a locking hole 304 and the second connecting part 308 includes a claw 214.

[0088] In the locked position, the claw 214 inserts into the slot 304 to restrict the electrical control box 20 from downward movement relative to the housing 30 (e.g., Figure 8 (Movement in the downward direction).

[0089] In the locked position, the claw 214 inserts into the locking hole 304, which not only restricts the downward movement of the electrical control box 20 relative to the housing 30, but also ensures a stable connection between the electrical control box 20 and the housing 30. When disassembling the electrical control box 20, the claw 214 can smoothly disengage from the locking hole 304, allowing the electrical control box 20 to be safely separated from the housing 30. This design ensures the electrical control box 20 is securely installed while effectively preventing accidental detachment during disassembly, thus improving operational safety.

[0090] Optionally, such as Figure 9 As shown, the locking hole 304 includes a first hole segment 305 and a second hole segment 306 that are connected. The opening area of ​​the first hole segment 305 is larger than the opening area of ​​the second hole segment 306. In the locked position, the claw 214 is confined within the second hole segment 306. In the disengaged position, the locking hole 304 is disengaged through the first hole segment 305.

[0091] The first hole section 305 has a larger opening area, while the second hole section 306 has a smaller opening area. This allows the claw 214 to be securely confined within the second hole section 306 in the locked position, ensuring a tight connection between the electrical control box 20 and the housing 30. When the electrical control box 20 needs to be disassembled, the claw 214 slides from the second hole section 306 into the first hole section 305. Since the opening size of the first hole section 305 is not smaller than the size of the claw 214, the claw 214 can smoothly disengage from the first hole section 305, thus not affecting the disassembly of the electrical control box 20. This design not only improves the reliability of the claw 214 locking within the locking hole 304 but also optimizes the disassembly process of the electrical control box 20, ensuring that the electrical control box 20 will not suddenly fall due to loss of restraint during disassembly, further improving the safety of disassembly.

[0092] Optionally, the claw 214 includes a first connecting section 215 and a second connecting section 216. In the locked position, the first connecting section 215 is located within the second hole section 306; the second connecting section 216 is connected to one end of the first connecting section 215 and the connection point forms an angle. In the locked position, the second connecting section 216 extends out of the second hole section 306 and abuts against the housing 30 or the electrical control box 20 where the claw hole 304 is located.

[0093] One end of the first connecting segment 215 is connected to one end of the second connecting segment 216, and the other end of the first connecting segment 215 is connected to the housing 30 or the electrical control box 20 where the claw 214 is located. The other end of the second connecting segment 216 forms a free end. In the locked position, the surface of the second connecting segment 216 facing the housing 30 or the electrical control box 20 where the claw 214 is located abuts against the housing 30 or the electrical control box 20 where the locking hole 304 is located, so as to restrict the electrical control box 20 from moving downward relative to the housing 30. When it is necessary to disassemble the electrical control box 20, the claw 214 slides relative to the locking hole 304, so that the first connecting segment 215 moves into the first hole segment 305, the second connecting segment 216 passes through the first hole segment 305, and the claw 214 is disengaged from the first hole segment 305.

[0094] Taking the pawl 214 located in the electrical control box 20 as an example, one end of the first connecting section 215 is connected to one end of the second connecting section 216, the other end of the first connecting section 215 is connected to the electrical control box 20, and the other end of the second connecting section 216 forms a free end. In the locked position, the surface of the second connecting section 216 facing the electrical control box 20 abuts against the housing 30.

[0095] The angled design of the first connecting section 215 and the second connecting section 216 allows the claw 214 to engage more tightly with the locking hole 304 when locked, enhancing the connection strength between the electrical control box 20 and the housing 30. In the disengaged position, the claw 214 can smoothly disengage from the locking hole 304. This design ensures the electrical control box 20 is securely installed while effectively preventing accidental detachment during disassembly, thus improving operational safety.

[0096] Optionally, such as Figure 10 As shown, the side wall (i.e., the enclosure 10) of the housing 30 is provided with a mounting groove 301, that is, the mounting groove 301 penetrates the side wall of the housing 30, and the electrical control box 20 is located in the mounting groove 301; when the locking hole 304 is provided in the housing 30, the first hole segment 305 and the second hole segment 306 are arranged sequentially along the direction from the side wall of the housing 30 penetrated by the mounting groove 301 to the middle of the housing 30; when the locking hole 304 is provided in the electrical control box 20, the second hole segment 306 and the first hole segment 305 are arranged sequentially along the direction from the side wall of the housing 30 penetrated by the mounting groove 301 to the middle of the housing 30.

[0097] When installing the electrical control box 20, place the electrical control box 20 at the entrance of the mounting slot 301 and ensure that the second connecting part 308 is aligned with the first connecting part 303, that is, check the alignment of the claw 214 and the hole 304.

[0098] Taking the case where the locking hole 304 is located in the housing 30 as an example, the electrical control box 20 is slowly pushed into the housing 301 along the direction from the side wall of the housing 30 through which the mounting groove 301 penetrates to the middle of the housing 30. During the pushing process, the locking claw 214 first contacts the first hole section 305 of the locking hole 304. Because the opening area of ​​the first hole section 305 is relatively large, the locking claw 214 can smoothly enter the first hole section 305 without encountering excessive resistance.

[0099] Continue pushing the electrical control box 20 in until the claw 214 reaches the second hole section 306 of the locking hole 304. The opening area of ​​the second hole section 306 is small, and the claw 214 is confined within the second hole section 306, thereby locking the electrical control box 20 to the housing 30.

[0100] When disassembling the electrical control box 20, use appropriate tools or manual operation to pull the electrical control box 20 in the opposite direction from the side wall of the housing 30 through which the mounting groove 301 passes to the middle of the housing 30, so that the claw 214 slides from the second hole section 306 into the first hole section 305. After the claw 214 enters the first hole section 305, slowly pull the electrical control box 20 out of the mounting groove 301.

[0101] When the locking hole 304 is located on the housing 30, the first hole segment 305 and the second hole segment 306 are sequentially arranged along the direction from the side wall of the housing 30 through which the mounting groove 301 penetrates to the middle of the housing 30. When the locking hole 304 is located on the electrical control box 20, the second hole segment 306 and the first hole segment 305 are sequentially arranged along the direction from the side wall of the housing 30 through which the mounting groove 301 penetrates to the middle of the housing 30. The positions of the first hole segment 305 and the second hole segment 306 correspond to the direction in which the electrical control box 20 is pushed into or removed from the mounting groove 301.

[0102] like Figure 9 As shown, the chuck 214 can be formed by stamping.

[0103] The number of first connecting parts 303 is one or more, and the number of first connecting mating parts 213 is equal to the number of first connecting parts 303.

[0104] When there are multiple first connecting parts 213, the multiple first connecting parts 213 are located on opposite side walls of the electrical control box 20.

[0105] Optionally, such as Figure 8 and Figure 9 As shown, the electrical control box 20 includes a box 212 and a cover 211 covering the box 212. The housing 30 is provided with a connecting plate 302, which is located on the side of the bottom wall 220 of the box 212 away from the cover 211. The first connecting part 303 is located on the connecting plate 302.

[0106] The cover 211 and the box 212 are detachably connected. For example, the cover 211 is provided with a third connecting part 218, and the box 212 is provided with a third connecting mating part. The third connecting part 218 and the third connecting mating part are detachably connected by a snap-fit. The third connecting part 218 and the third connecting mating part can be connected by screws or snap-fit, etc.

[0107] The connection between the connecting plate 302 and the housing 30 is bent, or in other words, the side wall of the housing 30 is bent toward the mounting groove 301 to form the connecting plate 302. The cover 211 is placed over the open end of the box 212, and the bottom wall 220 of the box 212 faces the cover 211. The connecting plate 302 is located on the outer wall surface of the bottom wall 220 of the box 212, wherein the direction toward the inside of the box 212 is called the inside, and the direction away from the inside of the box 212 is called the outside.

[0108] The first connecting part 303 is provided on the connecting plate 302, and the first connecting mating part 213 is provided on the bottom wall 220 of the box body 212. In this way, when disassembling the electrical control box 20, the third connecting part 218 is separated from the third connecting mating part first, and the cover 211 is removed. If the claw 214 is stamped or the card hole 304 is provided on the bottom wall 220 of the box body 212, the claw 214 and the card hole 304 can be seen directly after removing the cover 211, so that the claw 214 can be easily removed from the card hole 304.

[0109] Optionally, such as Figure 7 The diagram shows the indoor unit after the cover of the electrical control box is removed. The housing 30 is provided with a second connecting part 308, and the electrical control box 20 is provided with a second connecting mating part 217. The second connecting part 308 and the second connecting mating part 217 are detachably connected.

[0110] By providing the second connecting part 308 and the second connecting mating part 217, the connection strength between the electrical control box 20 and the housing 30 is further enhanced.

[0111] The second connecting part 308 and the second connecting mating part 217 can be connected by screws or by snap-fit.

[0112] For example, the second connecting portion 308 includes a second connecting structure 102, and the second connecting mating portion 217 includes a second connecting mating structure 201; as another example, the second connecting portion 308 includes a third connecting structure 103, and the second connecting mating portion 217 includes a third connecting mating structure 204.

[0113] Optionally, the second connecting part 308 is provided on the connecting plate 302.

[0114] The second connecting part 308 is disposed on the connecting plate 302, further optimizing the structural layout of the electrical control box 20 and the housing 30. This design makes the connection between the electrical control box 20 and the housing 30 more compact, reducing space occupation, while improving the stability and reliability of the connection. Moreover, after removing the cover 211, the second connecting mating part 217 can be seen, thus allowing for convenient and intuitive separation of the second connecting part 308 and the second connecting mating part 217.
