Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to a fixing structure for an air conditioner drain pipe and an air conditioner. Background Art

[0002] With the improvement of people's living standards, air conditioners have become common household appliances. During operation, air conditioners generate condensate, so the fixed installation of the air conditioner drain pipe is particularly important.

[0003] In the prior art, the drain pipe is usually fixed with iron hoop metal parts, which are difficult to disassemble and require specific tools for installation and disassembly, resulting in low installation efficiency and poor user experience for self-cleaning;

[0004] It is also common to set a buckle on the joint of the drain pipe and a slot / card hole on the air conditioner bottom case to achieve the snap connection between the drain pipe and the bottom case. However, the contact area of the buckle is small, and the stability of the buckle connection is poor. Summary of the Invention

[0005] To solve the above technical problems, a first aspect of the present invention provides a fixing structure for an air conditioner drain pipe, including a pressing plate, a bottom case, and a drain pipe;

[0006] The pressing plate is connected to the bottom case, and the drain pipe is located between the pressing plate and the bottom case.

[0007] The present invention fixes the drain pipe with a pressing plate, providing uniform and stable pressure for the fixation of the drain pipe, with good stability.

[0008] Furthermore, the pressing plate and the bottom case are snap-connected to fix the drain pipe. By setting a snap structure on the pressing plate and the bottom case, the present invention realizes the fixation of the drain pipe. The device has a simple structure, is convenient for assembly and disassembly, and is easy to replace.

[0009] Furthermore, the pressing plate includes a body, a first fixing arm and a second fixing arm connected to the body; the first fixing arm and the second fixing arm are located on both sides of the body.

[0010] Furthermore, the body includes a groove, the drain pipe includes a joint, and a closed end of the joint includes a clamping portion, which is matched with the groove. By setting a groove on the body of the pressing plate corresponding to the drain pipe and a clamping portion on the joint of the drain pipe, the present invention can limit the joint of the drain pipe, with reliable fixation, prevent the pipeline from slipping off from the side, and further enhance the stability of the drain pipe fixation.

[0011] Furthermore, the included angles between the first fixing arm and the second fixing arm and the body are 120° - 180° respectively. By limiting the included angles between the fixing arms and the body, the present invention facilitates the installation and fixation of the drain pipe and the groove on the body.

[0012] Further, the first fixing arm is inserted or snapped into the bottom case, and the second fixing arm is snap-connected to the bottom case.

[0013] Further, the first fixing arm is rotatably connected to the bottom case. In the present invention, one end of the pressing plate is rotatably connected to the bottom case, and the other end is snap-connected to the bottom case. When it is necessary to separate the drain pipe from the air conditioner bottom case, only the snap structure at one end needs to be opened and the pressing plate is rotated, which is simple, convenient to operate and improves the efficiency.

[0014] Further, the first fixing arm is inserted and snapped into the bottom case.

[0015] Further, the first fixing arm includes a first snap member, and a snap shaft is included on the bottom case, and the first snap member is matched with the snap shaft.

[0016] Further, the first fixing arm is provided with a first convex portion, and a limiting hole is provided on the bottom case, or the first fixing arm is provided with a limiting hole, and a first convex portion is provided on the bottom case, and the limiting hole is matched with the first convex portion.

[0017] In the present invention, by providing a limiting structure on the first fixing arm, when the pressing plate is opened, the limiting hole limits the first fixing arm to prevent the pressing plate from detaching from the bottom case and hindering the operation of the staff.

[0018] Further, the second fixing arm is provided with a first snap hole, and a second snap member is provided around the position where the bottom case is matched with the drain pipe, and the first snap hole is matched with the second snap member.

[0019] Further, the second snap member includes a first hook and a pressing portion, one end of the pressing portion is connected to the bottom case, and the other end is connected to the first hook, or the pressing portion is located on the side of the first hook away from the bottom case, and the first hook is matched with the first snap hole.

[0020] Further, the inner side of the second snap member is separated from the bottom case to form a cavity. In the present invention, by providing a cavity on the inner side of the second snap member, on the one hand, it is beneficial for the second snap member to be demolded, and on the other hand, it provides an elastic deformation space for the second snap member to ensure the smoothness of snap connection or snap detachment.

[0021] Further, the first hook is bent towards the direction of the drain pipe, the first hook has a "U" - shaped structure, and the edge of the first snap hole is located in the recessed part of the "U" - shaped structure.

[0022] In the present invention, by setting the second buckle member as a "U"-shaped buckle structure with a bent portion, the clamping strength is increased, making it difficult for the first hook and the first clamping hole to disengage, and the length of the second fixing arm is reduced so that its edge does not protrude from the edge of the bottom case.

[0023] Furthermore, anti-slip ribs are provided on the surface of the pressing portion. By providing the anti-slip ribs in the present invention, the friction coefficient of the contact surface is increased, preventing sliding during pressing and facilitating the pressing of the buckle structure.

[0024] Furthermore, the second fixing arm is provided with a second convex portion, and a limiting groove is provided on the bottom case, and the limiting groove cooperates with the second convex portion.

[0025] In the present invention, by providing a limiting structure near the buckle structure of the second fixing arm, the movement of the pressing plate along the direction of the second fixing arm is restricted to prevent the risk of the buckle connection being disengaged due to the deformation of the pressing plate, ensuring stable buckle connection.

[0026] Furthermore, second convex portions are provided on both sides of the second fixing arm, a limiting groove is provided on the upper surface of the bottom case, the second convex portions and the limiting groove are triangular, and the limiting groove cooperates with the second convex portions.

[0027] In the present invention, by setting the second convex portion and the limiting groove as triangular, a guiding and limiting function can be achieved to prevent the risk of the buckle connection being disengaged due to the deformation of the pressing plate, ensuring stable buckle connection.

[0028] An alternative solution is that the second fixing arm is provided with a second hook, a second clamping hole is provided on the upper surface of the bottom case, and the second hook cooperates with the second clamping hole.

[0029] In the present invention, by providing a clamping hole on the upper surface of the bottom case that is snap-connected to the hook of the second fixing arm, the snap connection is stable, the structure is simple, and the manufacturing cost is reduced.

[0030] In the second aspect of the present invention, an air conditioner is provided. The air conditioner includes the air conditioner drain pipe fixing structure provided by the present invention.

Therefore, in the present invention, the drain pipe is fixed by the pressing plate, the structure is simple, uniform and stable pressure is provided for the fixing of the drain pipe, and the stability is good.

[0046] See attached Figure 1 , The pressing plate 1 and the bottom shell 2 are snap-connected to fix the drain pipe 3. Therefore, in the present invention, by providing a snap structure on the pressing plate and the bottom shell, the fixing of the drain pipe is realized, the device structure is simple, convenient for assembly and disassembly, and convenient for replacement.

[0047] See attached Figure 2 and 3 , The pressing plate 1 includes a main body 11, a first fixing arm 12 and a second fixing arm 13 connected to the main body 11; the first fixing arm 12 and the second fixing arm 13 are located on both sides of the main body.

[0048] The main body 11 includes a groove 112 for restricting the lateral movement of the drain pipe 3, further enhancing the stability of the drain pipe fixing.

[0049] First reinforcing ribs 111 are provided in the circumferential direction of the main body 11, and second reinforcing ribs 133 are provided on the second fixing arm 13. Therefore, in the present invention, by providing reinforcing ribs on the pressing plate, the strength of the pressing plate can be enhanced, the pressing plate can be prevented from breaking, and the stable connection of the snap structure can be ensured.

[0050] See attached Figure 2 , The included angles between the first fixing arm 12 and the second fixing arm 13 and the main body 11 are 120° - 180° respectively. Therefore, in the present invention, by restricting the included angles between the fixing arms and the main body, the installation and fixing of the drain pipe and the groove of the main body are facilitated.

[0051] It should be noted that the first fixing arm 12 can be inserted or snap-connected to the bottom shell 2, and the second fixing arm 13 is snap-connected or screwed to the bottom shell 2. Insertion is a non-deformable connection, and snap connection is a deformable connection.

[0052] The insertion or snap connection between the first fixing arm 12 and the bottom shell 2 forms a rotatable connection form, and the second fixing arm 13 is snap-connected to the bottom shell 2.

[0053] Therefore, in the present invention, by rotatably connecting one end of the pressing plate to the bottom shell and snap-connecting the other end to the bottom shell, when it is necessary to separate the drain pipe from the air conditioner bottom shell, only need to open the snap structure at one end and rotate the pressing plate, the operation is simple, convenient, and the efficiency is improved.

[0054] In this embodiment, the first fixing arm 12 is snap-connected to the bottom case 2, with one end inserted and the other end snap-connected. The first fixing arm 12 includes a first snap member 121, and the first snap member 121 cooperates with the shaft on the bottom case 2, enabling the first snap member 121 to rotate around the shaft on the bottom case 2.

[0055] Preferably, the cross-section of the first snap member 121 is a non-closed semi-circular groove.

[0056] The first fixing arm 12 further includes a first convex portion 122 for cooperating with the hole on the bottom case 2 to limit the first fixing arm 12.

[0057] The second fixing arm 13 includes a first snap hole 131, and the first snap hole 131 cooperates with the snap member on the bottom case 2 to achieve the snap connection between the second fixing arm 13 and the bottom case 2.

[0058] The second fixing arm 13 further includes a second convex portion 132 for cooperating with the groove on the bottom case 2 to limit the movement of the pressing plate 1 along the second fixing arm 12.
