[0045] 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.
[0046] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0047] Combination Figures 1-12 As shown, this embodiment of the present disclosure provides an indoor unit, including an evaporator 10, a first tube sheet 20, and a second tube sheet 30.
[0048] like Figures 7 to 10As shown, the evaporator 10 includes a first end 101 and a second end 102 disposed opposite to each other; a first tube sheet 20 is disposed at the first end 101 and is provided with a first connecting portion 210; a second tube sheet 30 is disposed at the second end 102 and is provided with a first connecting mating portion 310; wherein, the first connecting portion 210 and the first connecting mating portion 310 are directly connected to connect the first end 101 and the second end 102.
[0049] The first connecting part 210 and the first connecting mating part 310 are directly connected, allowing the first tube sheet 20 and the second tube sheet 30 to be directly connected together. This eliminates the need for traditional tube sheet supports, reduces the number of parts, simplifies the structure, and thus lowers production costs and improves production efficiency. At the same time, this direct connection method also helps improve the stability and reliability of the structure, reducing the risk of air conditioning performance degradation due to problems such as loose screws.
[0050] Optionally, such as Figures 1 to 10 As shown, the first connecting part 210 and the first connecting mating part 310 are engaged. One of the first connecting part 210 and the first connecting mating part 310 includes a first latch 204, and the other includes a first slot 308. The first latch 204 engages with the first slot 308 and can move relative to the first slot 308 between a first locked position and a first unlocked position. In the first locked position, the first latch 204 is confined within the first slot 308. In the first unlocked position, the first latch 204 can disengage from the first slot 308.
[0051] When connecting the first tube sheet 20 and the second tube sheet 30, the first end 101 and the second end 102 of the evaporator 10 are first connected to the first tube sheet 20 and the second tube sheet 30 respectively. The first tube sheet 20 and the second tube sheet 30 are aligned, and the second end 102 of the evaporator 10 is pressed down. During the pressing process, the first claw 204 is aligned with the entrance of the first slot 308 and enters the first slot 308. At this time, the first claw 204 is in the first unlocked position. The pressed second end 102 is released. Under the action of the elastic restoring force of the evaporator 10 itself, the pressed second end 102 rebounds, which drives the second tube sheet 30 to rebound. The first claw 204 moves relative to the first slot 308 to the first locked position. The first claw 204 is fastened in the first slot 308, and the locking between the first tube sheet 20 and the second tube sheet 30 is completed, so that the first tube sheet 20 and the second tube sheet 30 are firmly fixed together.
[0052] By employing the engagement of the first claw 204 and the first slot 308, the connection between the first tube sheet 20 and the second tube sheet 30 is not only more robust but also enables rapid assembly and disassembly. Specifically:
[0053] During assembly, the first end 101 or the second end 102 of the evaporator 10 is pressed down, and the pressing direction is as follows when the second end is pressed down: Figure 3 As shown by the middle arrow, align the first claw 204 with and insert it into the first slot 308, then release to allow the evaporator 10 to spring back, thus completing the connection. This design greatly simplifies the assembly process and improves assembly efficiency.
[0054] The first latch 204 is firmly held within the first latching groove 308 by the rebound force of the evaporator 10, ensuring the stability of the connection. Even during long-term use, this latching structure is not prone to loosening.
[0055] When disassembly is required, simply press down again on either the first end 101 or the second end 102 of the evaporator 10 to disengage the first claw 204 from the first slot 308, and disassembly can be easily completed. This removability not only facilitates maintenance and replacement of parts, but also improves the ease of product maintenance.
[0056] By using the snap-fit connection between the first connecting part 210 and the first connecting mating part 310, the number of parts is reduced compared to screw connections, thus lowering production costs. At the same time, it also reduces potential risks caused by screw loosening and other issues, further improving the overall performance of the product and the user experience.
[0057] Optionally, such as Figure 1 As shown, the first claw 204 includes a first connecting segment 205 and a second connecting segment 206.
[0058] One end of the first connecting segment 205 is connected to the first tube sheet 20 or the second tube sheet 30 where the first claw 204 is located; one end of the second connecting segment 206 is connected to the other end of the first connecting segment 205 and the connection point forms a bend, and the other end of the second connecting segment 206 forms a free end.
[0059] like Figure 10 As shown, in the first locked position, the first connecting segment 205 is located in the first slot 308, and the second connecting segment 206 extends out of the first slot 308 and abuts against the first tube plate 20 or the second tube plate 30 where the first slot 308 is located, thereby restricting the first tube plate 20 from moving away from the second tube plate 30 along the line connecting the first tube plate 20 and the second tube plate 30.
[0060] like Figure 6 As shown, in the first unlocked position, the first connecting segment 205 is still located in the first slot 308, but the second connecting segment 206 no longer abuts against the first tube plate 20 or the second tube plate 30 where the first slot 308 is located, and there is no longer a limit between the first tube plate 20 and the second tube plate 30, so that the first claw 204 can be dislodged from the first slot 308.
[0061] likeFigure 1 As shown, the first tube sheet 20 includes a first plate body 201, the first connecting part 210 includes a first claw 204, one end of the first connecting section 205 is connected to the first plate body 201, the other end of the first connecting section 205 is connected to one end of the second connecting section 206, and the other end of the second connecting section 206 forms a free end.
[0062] The bending structure at the connection between the first connecting segment 205 and the second connecting segment 206 allows the first claw 204 to be securely confined within the first slot 308 in the first locked position, while it can easily disengage from the first slot 308 in the first unlocked position. This design not only ensures the stability of the connection between the first tube sheet 20 and the second tube sheet 30, but also improves the ease of assembly and disassembly of the first tube sheet 20 and the second tube sheet 30, further optimizing the connection performance between the first tube sheet 20 and the second tube sheet 30.
[0063] Optionally, the size of the first slot 308 is larger than the size of the first connecting segment 205, so that the first connecting segment 205 can move relative to the first slot 308 within the first slot 308, for example, moving along the length direction of the first slot 308, so that the first claw 204 can move relative to the first slot 308 between the first locked position and the first unlocked position.
[0064] The size of the second connecting segment 206 is less than, equal to or slightly larger than the size of the first slot 308, so that the second connecting segment 206 can pass through the first slot 308.
[0065] The length direction of the first slot 308 is the same as the downward pressing direction of the evaporator 10, and the downward pressing direction of the evaporator 10 is the width direction of the evaporator 10.
[0066] The second connecting segment 206 has a first guide slope 212 at the end opposite to the first connecting segment 205, i.e., the free end of the second connecting segment 206, to guide the second connecting segment 206 into the first slot 308.
[0067] Along the direction of the first claw 204 moving from the first unlocked position to the first locked position, the free end of the second connecting segment 206 is inclined in a direction away from the first connecting segment 205 to form a first guide slope 212. When the second connecting segment 206 is inserted into and exits the first slot 308, and when the second connecting segment 206 moves from the first unlocked position to the first locked position, the first guide slope 212 guides the movement of the first claw 204, preventing jamming during its movement.
[0068] Optionally, such as Figures 1 to 10As shown, one of the first connecting part 210 and the first connecting mating part 310 further includes a second claw 304, and the other includes a second slot 208. The second claw 304 engages with the second slot 208 and can move relative to the second slot 208 between a second locked position and a second unlocked position. In the second locked position, the second claw 304 is confined within the second slot 208. In the second unlocked position, the second claw 304 can disengage from the second slot 208.
[0069] When connecting the first tube sheet 20 and the second tube sheet 30, the first end 101 and the second end 102 of the evaporator 10 are first connected to the first tube sheet 20 and the second tube sheet 30 respectively. The first tube sheet 20 and the second tube sheet 30 are aligned, and the second end 102 of the evaporator 10 is pressed down. During the pressing process, the second claw 304 is aligned with the entrance of the second slot 208 and enters the second slot 208. At this time, the second claw 304 is in the second unlock position. The pressed first end 101 is released, and the pressed second end 102 rebounds under the elastic restoring force of the evaporator 10 itself, which drives the second tube sheet 30 to rebound. The second claw 304 moves relative to the second slot 208 to the second locking position. The second claw 304 is fastened in the second slot 208, completing the locking between the first tube sheet 20 and the second tube sheet 30, so that the first tube sheet 20 and the second tube sheet 30 are firmly fixed together.
[0070] By employing the engagement of the second claw 304 and the second slot 208, the connection between the first tube sheet 20 and the second tube sheet 30 is not only more robust but also enables rapid assembly and disassembly. Specifically:
[0071] During assembly, by pressing down on either the first end 101 or the second end 102 of the evaporator 10, the second claw 304 is aligned and inserted into the second slot 208. Then, releasing the pressure allows the evaporator 10 to spring back, thus completing the connection. This design greatly simplifies the assembly process and improves assembly efficiency.
[0072] The second latch 304 is firmly contained within the second latch slot 208 under the rebound force of the evaporator 10, ensuring the stability of the connection. Even during long-term use, this latching structure is not prone to loosening.
[0073] When disassembly is required, simply press down on either the first end 101 or the second end 102 of the evaporator 10 again to disengage the second claw 304 from the second slot 208, and disassembly can be easily completed. This removability not only facilitates maintenance and replacement of parts, but also improves the ease of product maintenance.
[0074] By using the snap-fit connection between the first connecting part 210 and the first connecting mating part 310, the number of parts is reduced compared to screw connections, thus lowering production costs. At the same time, it also reduces potential risks caused by screw loosening and other issues, further improving the overall performance of the product and the user experience.
[0075] The second claw 304 includes a third connecting section 305 and a fourth connecting section 306. One end of the third connecting section 305 is connected to the first tube sheet 20 or the second tube sheet 30 where the second claw 304 is located. One end of the fourth connecting section 306 is connected to the other end of the third connecting section 305 and a bend is formed at the connection. The other end of the fourth connecting section 306 forms a free end.
[0076] like Figure 8 As shown, in the second locked position, the third connecting segment 305 is located in the second slot 208, and the fourth connecting segment 306 extends out of the second slot 208 and abuts against the first tube plate 20 or the second tube plate 30 where the second slot 208 is located, thereby restricting the first tube plate 20 from moving away from the second tube plate 30 along the line connecting the first tube plate 20 and the second tube plate 30.
[0077] like Figure 4 As shown, in the second unlocked position, the third connecting segment 305 is still located in the second slot 208, but the fourth connecting segment 306 no longer abuts against the first tube plate 20 or the second tube plate 30 where the second slot 208 is located, and there is no longer a limit between the first tube plate 20 and the second tube plate 30, so that the second claw 304 can be dislodged from the second slot 208.
[0078] like Figure 1 As shown, the first tube sheet 20 includes a second plate body 301, the first connecting part 210 includes a second claw 304, one end of the third connecting section 305 is connected to the second plate body 301, the other end of the third connecting section 305 is connected to one end of the fourth connecting section 306, and the other end of the fourth connecting section 306 forms a free end.
[0079] The bending structure at the connection between the third connecting segment 305 and the fourth connecting segment 306 allows the second claw 304 to be securely confined within the second slot 208 in the second locked position, while easily disengaging from the second slot 208 in the second unlocked position. This design not only ensures the stability of the connection between the first tube sheet 20 and the second tube sheet 30, but also improves the ease of assembly and disassembly of the first tube sheet 20 and the second tube sheet 30, further optimizing the connection performance between the first tube sheet 20 and the second tube sheet 30.
[0080] Optionally, such as Figures 3 to 10As shown, the size of the second slot 208 is larger than the size of the third connecting segment 305, so that the second claw 304 can move relative to the second slot 208 between the second locked position and the second unlocked position.
[0081] The size of the fourth connecting segment 306 is less than, equal to or slightly larger than the size of the second slot 208, so that the fourth connecting segment 306 can pass through the second slot 208.
[0082] The length direction of the second slot 208 is the same as the downward pressing direction of the evaporator 10, and the downward pressing direction of the evaporator 10 is the width direction of the evaporator 10.
[0083] Optionally, the fourth connecting segment 306 is provided with a second guide slope 311 at the end opposite to the third connecting segment 305, i.e., the free end of the fourth connecting segment 306, to guide the fourth connecting segment 306 into the second slot 208.
[0084] Along the direction in which the second claw 304 moves from the second unlocked position to the second locked position, the free end of the fourth connecting segment 306 is inclined in a direction away from the third connecting segment 305 to form a second guide slope 311. When the fourth connecting segment 306 is inserted into and exits the second slot 208, and when the fourth connecting segment 306 moves from the second unlocked position to the second locked position, the second guide slope 311 guides the movement of the second claw 304, preventing jamming during its movement.
[0085] Optionally, such as Figures 1 to 10 As shown, the first connecting part 210 includes a first claw 204 and a second slot 208, the first connecting mating part 310 includes a first slot 308 and a second claw 304, the first claw 204 includes a first bending part 207, the bend formed at the connection between the first connecting segment 205 and the second connecting segment 206 is the first bending part 207, the second claw 304 includes a second bending part 307, the bend formed at the connection between the third connecting segment 305 and the fourth connecting segment 306 is the second bending part 307, the opening direction of the first bending part 207 is opposite to the opening direction of the second bending part 307.
[0086] The length of the first card slot 308 is opposite to that of the second card slot 208, and the length of the second card slot 208 is parallel to that of the second card slot 208.
[0087] By setting the opening directions of the first bending portion 207 and the second bending portion 307 to be opposite, when the first claw 204 is in the first locking position and the second claw 304 is in the second locking position, it is possible to restrict the movement of the first tube sheet 20 and the second tube sheet 30 along the line connecting the first tube sheet 20 and the second tube sheet 30, and also to restrict the movement of the first tube sheet 20 and the second tube sheet 30 along the downward pressing direction of the evaporator 10.
[0088] The first connecting part 210 includes a first claw 204 and a second slot 208. The first connecting mating part 310 includes a first slot 308 and a second claw 304. The opening direction of the first bending part 207 is opposite to the opening direction of the second bending part 307, so that when the evaporator 10 is pressed down, the first claw 204 and the second claw 304 can be located in the first unlocking position and the second unlocking position respectively.
