Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit with a quick-release filter. Background Technology

[0002] As an indispensable device in modern homes and offices, one of the core functions of air conditioners is to regulate indoor temperature through internal circulation for cooling or heating. To ensure air quality and protect core components such as the internal evaporator, air conditioner indoor units are usually equipped with filters to remove dust and impurities from the air.

[0003] Over time, the filter will accumulate a large amount of dust, which not only affects the air conditioner's cooling and heating efficiency and increases energy consumption, but may also breed bacteria, affecting indoor air quality. Therefore, regularly disassembling and cleaning the filter is essential.

[0004] In existing technologies, the installation structure of filter screens is relatively simple, usually relying on multiple clips or simple sliding grooves for fixation. Users often face challenges when reinstalling the filter screen after cleaning. Due to the lack of an effective guiding and positioning mechanism, the installation process depends entirely on the user's experience and feel, making it difficult to ensure that the filter screen is accurately installed in the intended position on the first attempt.

[0005] The uncertainty inherent in this installation process can easily lead to misalignment or improper installation of the filter. An improperly installed filter not only fails to provide the intended filtration effect but may also generate vibration and noise during air conditioner operation, severely impacting the user experience. Therefore, the existing air conditioner filter installation structure has significant shortcomings in terms of ease of disassembly and assembly, as well as installation reliability.

[0006] Therefore, this utility model proposes an air conditioner indoor unit with a quick-release filter to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides an air conditioner indoor unit with a quick-release filter, aiming to improve the problems of cumbersome disassembly and misalignment or improper installation of air conditioner filters in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an air conditioner indoor unit with a quick-release filter, comprising: an air conditioner casing, a filter body, a guide roller; and a quick-release mechanism and a limiting mechanism.

The first spring and the ball cooperate to elastically abut against the surface of the pin, and the protruding end of the pin is pluggably engaged with one end of the filter body. The limiting mechanism is disposed along the sliding path of the guide rollers, and a guide rail is formed inside the limiting mechanism. The guide roller is rotatably disposed in the guide rail, and the limiting block in the limiting mechanism is movably disposed on the side wall of the guide rail. The second spring elastically abuts against the limiting block.

[0011] Preferably, the limiting block is formed as a guiding slope on one side facing the sliding direction of the guide roller, and as a limiting straight surface on the other side.

[0012] Preferably, the indoor unit of the air conditioner with a quick-release filter also includes a fixing block, which is fixed inside the air conditioner housing. The fixing block has a slot, and the other end of the filter body is inserted into the slot.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 4 This utility model provides an indoor air conditioner unit with a quick-release filter, which aims to solve the problems of cumbersome disassembly and misalignment or improper installation of air conditioner filters in the prior art.

[0025] The air conditioner indoor unit with a quick-release filter includes an air conditioner housing 1 and a filter body 4 detachably installed inside the air conditioner housing 1. An air conditioner cover 2 is hinged to the air conditioner housing 1, and a baffle plate 3 is rotatably connected to the air outlet of the air conditioner housing 1. An evaporator 6, a protective shell 8, a fixing block 704, a quick-release mechanism 5, and a limiting mechanism 7 are also fixedly installed inside the air conditioner housing 1. Guide rollers 701 are rotatably connected to both sides of the filter body 4. The filter body 4 is located on the air inlet side of the evaporator 6, and the protective shell 8 covers the outer periphery of the evaporator 6.

[0026] Specifically, the quick-release mechanism 5 is used to quickly lock and unlock the filter body 4. The quick-release mechanism 5 includes a handle 501, a pin 502, a first spring 503, and a ball 504. The handle 501 is integrally formed and connected to the outer end of the pin 502. The pin 502 is slidably disposed in the quick-release mechanism 5. The protruding end of the pin 502 is pluggably engaged with one end of the filter body 4. One end of the first spring 503 is fixed to the inner wall of the quick-release mechanism 5. The other end of the first spring 503 is connected to the ball 504. Under the elastic force of the first spring 503, the ball 504 elastically abuts against the surface of the pin 502, thereby providing a positioning feel and stable holding force when the pin 502 slides.

[0027] Furthermore, the limiting mechanism 7 is used to provide guidance and limit the installation position during the pulling process of the filter body 4. The limiting mechanism 7 is set along the sliding path of the guide roller 701. A guide rail for the guide roller 701 to roll is formed inside the limiting mechanism 7. The limiting mechanism 7 includes a limiting block 702 and a second spring 703. The limiting block 702 is movably set on the side wall of the guide rail and partially extends into the guide rail. One end of the second spring 703 elastically abuts against the inner wall of the limiting mechanism 7, and the other end of the second spring 703 elastically abuts against the limiting block 702. When the guide roller 701 slides in the guide rail and passes the limiting block 702, the guide roller 701 will first press down the limiting block 702. After passing the limiting block 702, the second spring 703 pushes the limiting block 702 to reset, thereby blocking and limiting the guide roller 701.

[0028] The quick-release mechanism 5 is fixedly connected to the inner wall of the air conditioner housing 1. The handle 501 is located outside the quick-release mechanism 5. The handle 501 is integrally connected to the outer end of the pin 502. The main body of the pin 502 slides through the quick-release mechanism 5. The protruding end of the pin 502 is used to engage with one end of the filter body 4 in an inserting or pulling manner. The first spring 503 and the ball 504 are set in the internal cavity of the quick-release mechanism 5. One end of the first spring 503 is fixed to the inner wall of the quick-release mechanism 5, and the other end is connected to the ball 504. Under the elastic force of the first spring 503, the ball 504 always elastically abuts against the surface of the pin 502. When the handle 501 is pulled or pushed, the pin 502 slides accordingly, and the ball 504 rolls or slides on the surface of the pin 502, providing a clear tactile feedback and stable holding force when the pin 502 switches between the locked and unlocked positions.

[0029] Meanwhile, a limiting mechanism 7 is also fixedly installed inside the air conditioner housing 1 to provide guidance and installation limit for the filter body 4. Guide rollers 701 are rotatably connected to both sides of the filter body 4. In the assembled state, the guide rollers 701 roll in the guide rail formed in the limiting mechanism 7. The limiting mechanism 7 also includes a limiting block 702 movably disposed on the side wall of the guide rail and a second spring 703 providing elastic force for it. One end of the second spring 703 elastically abuts against the inner wall of the limiting mechanism 7, and the other end elastically abuts against the limiting block 702, so that part of the limiting block 702 always tends to extend into the guide rail. The side of the limiting block 702 facing the sliding direction of the guide roller 701 forms a guiding slope, and the other side forms a limiting straight surface. This structure ensures that when the filter body 4 is installed, the guide roller 701 can be smoothly pressed down and slide past the guiding slope of the limiting block 702. After installation, the limiting straight surface of the limiting block 702 can reliably prevent the guide roller 701 from accidentally sliding out.

[0030] As a preferred embodiment, in order to reliably fix the other end of the filter body 4, the air conditioner indoor unit also includes a fixing block 704. The fixing block 704 is fixed inside the air conditioner housing 1 and has a slot. The other end of the filter body 4, that is, the end opposite to the end that cooperates with the quick release mechanism 5, is inserted into the slot of the fixing block 704. This method of one end being engaged and the other end being locked by the pin 502 ensures the stability of the filter body 4 in the installed state.

[0031] As another preferred embodiment, in order to protect the core components and guide airflow, an evaporator 6 is also provided inside the air conditioner housing 1, and the filter body 4 is located on the air inlet side of the evaporator 6 to filter the air before it enters the evaporator 6.

[0032] As another preferred embodiment, based on the above, the indoor unit of the air conditioner also includes a protective shell 8, which covers the outer periphery of the evaporator 6 and provides physical protection for the evaporator 6.

[0033] As another preferred embodiment, in order to facilitate user access to and operation of the internal filter body 4, an air conditioner cover 2 that can be hinged to the air conditioner housing 1 is provided.

[0034] In another preferred embodiment, in order to guide the direction of the airflow blown out by the air conditioner, a baffle plate 3 is rotatably connected to the air outlet of the air conditioner casing 1.

[0035] Working principle: When the filter body 4 needs to be disassembled for cleaning or replacement, the user first flips up the air conditioner cover 2, and then pulls the handle 501 of the quick-release mechanism 5 outward. The handle 501 drives the pin 502 to overcome the pressure exerted by the first spring 503 on the ball 504 and slide outward in the quick-release mechanism 5 until the protruding end of the pin 502 is completely pulled out from one end of the filter body 4, thus releasing the lock. Then, the other end of the filter body 4 is taken out from the slot of the fixing block 704. The filter body 4 is held and pulled outward. The guide rollers 701 on both sides of the filter body 4 will roll in the guide rail of the limiting mechanism 7. When the guide rollers 701 contact the limiting block 702, they will press down along its guide slope, thus sliding out smoothly and completing the disassembly.

[0036] When the filter body 4 needs to be installed, the user aligns the guide rollers 701 on both sides of the filter body 4 with the guide rail of the limiting mechanism 7 and pushes them inward. The guide rollers 701 roll in the guide rail until they contact the guide slope of the limiting block 702. Continue pushing in, and the guide rollers 701 will press down the limiting block 702 and slide past it. After sliding past, the second spring 703 immediately pushes the limiting block 702 back to its original position. The limiting surface of the limiting block 702 is now located behind the guide rollers 701, forming a reliable structural limit, indicating that the filter body 4 has been pushed into place. Then, press the other end of the filter body 4 into the slot of the fixing block 704. Finally, push the handle 501 of the quick release mechanism 5 inward so that the pin 502 is inserted into one end of the filter body 4, completing the final locking.
