Description

Technical Field

[0001] This application relates to the field of window air conditioners, and more specifically, to a sealing structure for a window air conditioner. Background Technology

[0002] Currently, window air conditioners (referred to as "window units") are an integrated air conditioning device. Their core feature is that all components, such as compressors, evaporators, condensers, and fans, are integrated into one unit. They need to be embedded in a window during installation to achieve cooling or heating of a single room. Therefore, window air conditioners are widely used in small spaces due to their convenient installation and the fact that they do not require separate piping. The existing technical solutions mentioned above have the following drawbacks: When installing traditional window air conditioners, the sealing is mostly achieved by using a single sponge strip or rubber gasket, which is squeezed by the air conditioner's own weight. After long-term use, the material is prone to aging and loss of elasticity, which leads to seal failure and the formation of gaps, resulting in leakage of hot and cold air and energy loss. In addition, external dust and rainwater can easily enter the room through the gaps. Utility Model Content

[0003] To overcome the above deficiencies, this application provides a sealing structure for a window air conditioner, which aims to improve the problem that the sealing structure is prone to aging and loss of elasticity, leading to sealing failure and the formation of gaps.

[0004] This application provides a sealing structure for a window air conditioner, including a window air conditioner and a sealing assembly; The window air conditioner includes a mounting base, an indoor unit, and an outdoor unit. The indoor unit is installed at the front end of the mounting base, and the outdoor unit is installed at the rear end of the mounting base. The mounting base is hollow to connect the interior of the indoor unit and the interior of the outdoor unit. A reserved slot is provided between the indoor unit and the outdoor unit. The sealing assembly includes a contoured cover and a sealing plate. The contoured cover is snapped into the reserved groove, and the sealing plate is slidably snapped into the contoured cover. A compression spring is connected between the contoured cover and the sealing plate, and a bellows plate is connected between the end of the contoured cover and the end of the sealing plate.

[0005] It features a robust and durable structure, enhancing safety during use. 1. Double fixation for wind and earthquake resistance: The contour cover is rigidly fixed to the window frame with countersunk screws, and the air conditioner is fixed to the contour cover with a snap-fit ​​structure. The double fixation ensures that the air conditioner has no risk of displacement or falling off in strong winds (wind speed ≤ level 10) or minor earthquakes (intensity ≤ 6 degrees), solving the loosening problem caused by traditional fixation with screws alone (traditional fixation has a loosening rate ≥ 10% in strong winds). 2. Durable materials, anti-aging and corrosion: The conformal cover is made of ABS engineering plastic (excellent weather resistance, no cracking in environments from -30℃ to 70℃), the sealing gasket and bellows are made of anti-aging rubber and polyurethane materials (resistant to ultraviolet aging, no hardening and cracking within 5 years), and the torsion spring and locking block of the snap-fit ​​structure are made of stainless steel (anti-corrosion and rust). The overall structure has an average annual failure rate of ≤2%, which is far lower than the 15% of traditional sealing solutions.

[0006] It also boasts a clean appearance, balancing practicality and aesthetics. 1. Concealed design with no protruding parts: The countersunk screws are fully embedded in the countersunk holes of the contour cover, the lever is set in the unlocking groove, the sealing plate fits tightly with the contour cover, and the overall structure has no exposed protruding parts, so it will not scratch clothes or affect the opening and closing of windows (such as sliding windows can slide normally). 2. Shape-fitting and visually harmonious: The shape of the contour cover matches the outline of the window frame and air conditioner, and the color can be customized (such as white or gray to match common window frame and air conditioner colors). After installation, it blends into the window and air conditioner, avoiding the messy appearance caused by the exposure of traditional sealing strips and foam strips, and improving the visual aesthetics of the interior and exterior.

[0007] In a preferred embodiment of this utility model, the side wall of the contour cover is provided with a countersunk hole, and a countersunk screw is fitted in the countersunk hole, with one end of the countersunk screw engaging with the window frame thread.

[0008] In a preferred embodiment of this utility model, the outer wall of the contour cover and the reserved slot provided in the window air conditioner are fixedly connected by a snap-fit ​​structure, and a sealing gasket is provided between the outer wall of the contour cover and the inner wall of the reserved slot.

[0009] In a preferred embodiment of the present invention, the sealing gasket is embedded in the outer wall of the conformal cover, and the sealing plate includes a rigid plate and a rubber gasket, with the rubber gasket attached to the lower surface of the rigid plate.

[0010] In a preferred embodiment of this utility model, the inner wall of the reserved groove is provided with a slot, and the snap-fit ​​structure includes a snap-fit ​​block and a torsion spring. The snap-fit ​​block is rotatably mounted on the side wall of the contour cover, and the torsion spring is used to push the snap-fit ​​block to spring up and snap-fit ​​with the slot.

[0011] In a preferred embodiment of this utility model, the contour cover is rotatably mounted with a rotating rod, the upper end of the locking block is fixedly connected to the rotating rod, the torsion spring is sleeved on the surface of the rotating rod, the first leg of the torsion spring abuts against the contour cover, and the second leg of the torsion spring abuts against the locking block.

[0012] In a preferred embodiment of this utility model, the torsion spring is disposed in a receiving groove hollowed out in the contour cover, the outer wall of the contour cover is provided with a groove, the locking block is installed in the groove, and two locking blocks are symmetrically arranged.

[0013] In a preferred embodiment of this utility model, one end of the rotating rod is fixed with a lever, and one end of the contour cover is provided with an unlocking groove. The lever is disposed in the unlocking groove. By moving the lever, the rotating rod is rotated, causing the locking block to separate from the locking groove, thereby unlocking the device. Beneficial effects

[0014] Significantly reducing energy consumption and noise, the system reduces air leakage between the air conditioner and window frame. Outdoor cold air (winter) or hot air (summer) cannot enter the room through the gap, reducing the air conditioner's cooling / heating load and power consumption. The sealed structure completely blocks outdoor noise (such as traffic noise and wind and rain noise) from entering the room through the gap, improving living comfort, especially suitable for residences facing the street or with severe noise pollution.

[0015] It has strong adaptive adjustment capabilities and can adapt to window frames in various scenarios. 1. Compensation for processing and deformation errors: The elastic compression of the spring and the deformation characteristics of the rubber pad can adapt to window frame flatness deviation ≤3mm and thickness deviation ≤7mm, eliminating the need for customized seals for different window frames and covering the specifications of household window frames; 2. Stable dynamic sealing: During long-term use, even if the window frame experiences slight displacement (≤2mm) due to temperature changes (thermal expansion and contraction) or vibration, the compression spring and rubber pad can adjust the sealing pressure in real time to ensure that the sealing performance does not decline, the sealing structure has a long service life, and avoids the failure of traditional sealing strips due to aging.

[0016] Easy to install and disassemble, reducing operating barriers and maintenance costs. 1. Tool-free quick assembly: The snap-fit ​​structure enables quick fixing of the air conditioner and the contour cover. When fixing the contour cover with countersunk screws, only an ordinary screwdriver is needed. A single person can complete the installation of the entire sealing structure within 10 minutes, reducing the difficulty of installation and allowing non-professionals to operate it. 2. Non-destructive disassembly and easy maintenance: The latching structure can be unlocked by lever, and the disassembly process does not require violent prying, so as not to damage the paint of the window frame or the air conditioner casing; when cleaning the air conditioner filter and repairing the outdoor unit, the air conditioner can be quickly disassembled, improving maintenance efficiency and reducing equipment failures caused by inconvenient maintenance.

The sealing assembly 300 includes a contoured cover 310 and a sealing plate 330. The contoured cover 310 is snapped into the reserved groove, and the sealing plate 330 is slidably snapped into the contoured cover 310. A compression spring 350 is connected between the contoured cover 310 and the sealing plate 330.

[0024] In a specific embodiment of this utility model, the side wall of the contour cover 310 is provided with a countersunk hole 311, and a countersunk screw 313 is fitted in the countersunk hole 311, with one end of the countersunk screw 313 threaded into the window frame.

[0025] In a specific embodiment of this utility model, the outer wall of the contour cover 310 is fixedly connected to the reserved slot provided in the window air conditioner 100 by a snap-fit ​​structure 500, and a sealing gasket 315 is provided between the outer wall of the contour cover 310 and the inner wall of the reserved slot.

[0026] In a specific embodiment of this utility model, the sealing gasket 315 is embedded in the outer wall of the contour cover 310, and the sealing plate 330 includes a rigid plate and a rubber gasket, with the rubber gasket attached to the lower surface of the rigid plate.

[0027] In a specific embodiment of this utility model, the inner wall of the reserved groove is provided with a slot 101, and the snap-fit ​​structure 500 includes a snap-fit ​​block 510 and a torsion spring 530. The snap-fit ​​block 510 is rotatably mounted on the side wall of the contour cover 310, and the torsion spring 530 is used to push the snap-fit ​​block 510 to spring up and snap-fit ​​with the slot 101.

[0028] In a specific embodiment of this utility model, the contour cover 310 is rotatably mounted with a rotating rod 550, the upper end of the locking block 510 is fixedly connected to the rotating rod 550, the torsion spring 530 is sleeved on the surface of the rotating rod 550, the first leg of the torsion spring 530 abuts against the contour cover 310, and the second leg of the torsion spring 530 abuts against the locking block 510.

[0029] In a specific embodiment of this utility model, the torsion spring 530 is disposed in the receiving groove of the hollow opening in the contour cover 310, the outer wall of the contour cover 310 is provided with a groove, the locking block 510 is installed in the groove, and two locking blocks 510 are symmetrically arranged.

[0030] In a specific embodiment of this utility model, a lever 570 is fixed to one end of the rotating rod 550, and an unlocking groove is provided at one end of the contour cover 310. The lever 570 is disposed in the unlocking groove. By moving the lever 570, the rotating rod 550 is rotated, causing the locking block 510 to separate from the locking groove 101, thereby unlocking.

[0031] The working principle of the sealing structure of this window air conditioner: Pre-installation and adaptation of the sealing structure 1. Fixing the contour cover 310 to the window frame: First, attach the contour cover 310 (shaped to fit the window frame outline, usually a U-shaped or rectangular frame, made of ABS engineering plastic, combining rigidity and toughness) to the window frame surface, ensuring that the countersunk hole 311 on the side wall of the contour cover 310 is aligned with the pre-set threaded hole in the window frame. Pass the countersunk screw 313 (made of 304 stainless steel, corrosion-resistant and rust-proof) through the countersunk hole 311 and engage it with the window frame thread. After tightening, the head of the countersunk screw 313 is fully embedded in the countersunk hole 311. 2. Pre-sealing of sealing gasket 315: The sealing gasket 315 (made of EPDM rubber, Shore hardness 50-60A, elastic recovery rate ≥90%) embedded in the outer wall of the contour cover 310 is tightly fitted to the surface of the window frame, initially filling the tiny gap (≤0.5mm) between the contour cover 310 and the window frame, forming the first layer of seal, blocking outdoor airflow from entering the room through the gap between the two.

[0032] Assembly of window air conditioner 100 and sealing structure 1. Snap-fit ​​Fixing and Quick Positioning: Align the mounting base 110 of the window air conditioner 100 with the contour cover 310, and push the air conditioner so that the contour cover 310 snaps into the reserved groove between the indoor unit 130 and the outdoor unit 150. During this process, the locking block 510 in the groove on the side wall of the contour cover 310 springs up under the elastic force of the torsion spring 530 (material 60Si2Mn, torque 5-8N·m), and precisely engages with the locking groove 101 on the inner wall of the reserved groove. The torsion spring 530 is sleeved on the surface of the rotating rod 550, with the first leg abutting against the inner wall of the contour cover 310 receiving groove and the second leg abutting against the locking block 510. Through elastic deformation, it continuously provides springing force to the locking block, ensuring that the locking block and the locking groove 101 are tightly engaged, realizing the quick fixing of the air conditioner and the contour cover 310 (no additional tools required, assembly can be completed by one person within 30 seconds). 2. Formation of double seal: The contour cover 310 and the inner wall of the reserved groove are further sealed by the sealing gasket 315 to prevent air leakage between the air conditioner and the contour cover 310; at the same time, the compression spring 350 (made of stainless steel, free length 50mm, compression amount 10-20mm) in the contour cover 310 releases its elastic force, pushing the sealing plate 330 (composed of a rigid plastic plate and a rubber gasket, the rubber gasket thickness 3-5mm) to slide downward, so that the rubber gasket on the lower surface of the sealing plate 330 is tightly pressed against the upper end of the window frame, forming a second seal, blocking the outdoor airflow from entering the room through the gap between the upper end of the window frame and the air conditioner.

[0033] Adaptive adjustment and dynamic sealing of sealing plate 330 1. Adaptive compensation of elastic compression: Due to minor errors in window frame processing (such as flatness deviation ≤1mm) or slight deformation of the window frame after long-term use, the elastic characteristics of the compression spring 350 can achieve adaptive adjustment of the sealing plate 330. The compression spring 350 continuously applies a pressure of 30-50N to ensure that the rubber pad of the sealing plate 330 is always tightly fitted to the upper surface of the window frame. Even if there are local protrusions or depressions in the window frame, the rubber pad can fill the gap through its own deformation (deformation rate ≤20%), avoiding the air leakage problem caused by poor adaptability of traditional rigid seals. 2. End sealing of bellows plate 331: The bellows plate 331 (made of polyurethane coated cloth, with an extension range of 20-30mm) connecting the end of the contour cover 310 and the end of the sealing plate 330 can freely extend and retract with the sliding of the sealing plate 330, while completely covering the gap between the two, preventing airflow from leaking into the end gap between the contour cover 310 and the sealing plate 330, forming a third seal and further improving the overall sealing performance.

[0034] Disassembly and maintenance of sealing structure When the air conditioner needs to be disassembled for cleaning or repair, the lever 570 (fixedly connected to the rotating rod 550) inside the unlocking slot of the contour cover 310 is moved to rotate the rotating rod 550. The rotating rod 550 simultaneously drives the locking block 510 to rotate downwards against the elastic force of the torsion spring 530, causing the locking block to separate from the locking slot 101 of the reserved slot, thus releasing the air conditioner from the contour cover 310. Then, the air conditioner can be pulled outwards to separate it from the contour cover 310. The operation is convenient (disassembly can be completed by one person within 1 minute) and will not damage the window frame or air conditioner components.
