Description

Technical Field

[0001] The present application relates to the field of household electrical appliances, and in particular to an air conditioner inner unit housing and an inner unit. Background Art

[0002] Regular filter replacement is crucial for wall-mounted air conditioners. Due to the presence of various impurities in indoor air, such as dust, pollen, and bacteria, these pollutants gradually accumulate in the air conditioner filter over time, affecting the air conditioner's cooling and heating performance, as well as air quality. Therefore, filter replacement is a crucial maintenance task. The need to periodically open the panel to replace the filter can lead to problems with frequent operation. After prolonged use, the top edge of the panel can warp when closed, significantly affecting the air conditioner's aesthetics.

[0003] On the one hand, a warped panel edge can disrupt the overall interior decor, making an otherwise neat and beautiful wall appear unnatural. This is undoubtedly a troubling issue for those who prioritize the aesthetics of their home. On the other hand, a warped panel edge can also affect the airtight seal of the air conditioner, causing cold or hot air to leak, reducing cooling and heating efficiency and increasing energy consumption. Furthermore, a warped panel edge can pose a safety hazard. For example, if accidentally touched, it could fall, posing a potential threat to life and property. Utility Model Content

[0004] In order to overcome the problem in the prior art that the upper edge of the air-conditioning panel warps after multiple openings and closings, the present application provides an air-conditioning inner unit housing and an inner unit, which can solve the problem of the upper edge of the air-conditioning panel warping.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: an air conditioner inner unit casing, comprising a middle frame and a panel arranged on the front side of the middle frame, the upper part of the panel is hinged to the upper part of the middle frame, the lower part of the panel is provided with a first clamping part, the lower part of the middle frame is provided with a second clamping part that is adapted and clamped to the first clamping part, the upper edge of the panel is provided with a third clamping part, and the middle frame is provided with a fourth clamping part that is adapted and clamped to the third clamping part.

[0006] After adopting the above technical solution, the present application has the following advantages: by setting a third clipping part on the upper edge of the panel and setting a corresponding fourth clipping part on the middle frame, the upper edge of the panel is still not easy to warp after the air conditioner is used for a long time and undergoes multiple repairs and disassemblies, thereby ensuring the aesthetics of the air conditioner. Moreover, since the lower part of the panel is provided with a first clipping part and the corresponding lower part of the middle frame is provided with a second clipping part, the lower part of the panel is also kept flat without warping, making the air conditioner more beautiful and integrated as a whole.

[0007] Furthermore, when the panel covers the front side of the middle frame, the panel shields the third clamping portion and the fourth clamping portion.

[0008] By adopting the above-mentioned technical solution, firstly, through the hidden design, when the panel cover is closed on the front side of the middle frame, the third clip part and the fourth clip part can be shielded, so that the air conditioner inner unit shell presents a simple and smooth appearance, which is more integrated with the interior decoration environment and enhances the overall coordination. Secondly, in terms of protecting the clip part, the clip part is avoided from being directly exposed to the outside to reduce wear and tear, and at the same time, dust accumulation is prevented, the service life of the clip part is extended, the stability of the connection between the panel and the middle frame is ensured, and the difficulty of cleaning and maintenance is reduced.

[0009] Furthermore, the fourth engaging portion is a slot opening upward, and the third engaging portion is a downwardly protruding engaging protrusion. When the panel is covered on the front side of the middle frame, the engaging protrusion extends from top to bottom into the slot and engages with the slot.

[0010] By adopting the above-mentioned technical solution, the cooperation between the protrusion and the groove can provide a strong connecting force. The gravity of the panel can make the third clamping part clamped in the fourth clamping part, ensuring that the panel will not easily loosen or detach during long-term use. In the front and rear directions, the third clamping part limits the fourth clamping part, preventing the upper edge of the panel from bulging outward and warping due to opening and closing, making the appearance of the panel more beautiful.

[0011] Furthermore, a reinforcing rib is provided on the top edge of the back side of the panel, and the third clamping portion is fixed to the lower end surface of the reinforcing rib.

[0012] The aforementioned technical solution, with reinforcing ribs installed along the top edge of the panel's backside, does not detract from the appearance of the air conditioner's indoor unit while significantly enhancing the panel's structural strength. The ribs disperse external forces acting on the panel, reducing the risk of deformation and damage during use. This rib ensures the panel remains flat, particularly when the panel is frequently opened and closed for filter changes, preventing warping or deformation.

[0013] Furthermore, there are multiple third clamping parts, and the multiple third clamping parts are arranged at intervals along the left-right direction, and the fourth clamping parts are arranged in a one-to-one correspondence with the third clamping parts.

[0014] By adopting the above-mentioned technical solution, multiple third clamping parts are evenly spaced along the left and right directions, and cooperate with the corresponding fourth clamping parts to achieve multi-point fixation. This multi-point fixation method can form a more secure connection between the panel and the middle frame, effectively preventing the panel from loosening, warping and other problems during long-term use. The uniform distribution of multiple clamping parts enables the panel to be evenly stressed when subjected to external force, avoiding deformation or damage caused by excessive local force.

[0015] Furthermore, there are multiple first clamping parts, which are arranged at intervals along the left-right direction, and the second clamping parts are arranged in a one-to-one correspondence with the first clamping parts.

[0016] By adopting the above-mentioned technical solution, multiple first clamping parts are arranged at intervals along the left and right directions, and cooperate with the corresponding second clamping parts to realize multi-point clamping. This multi-point clamping method greatly enhances the connection firmness between the lower part of the panel and the middle frame. During the use of the air conditioner, no matter whether it is affected by vibration, external force impact or long-term opening and closing, it can ensure that the lower part of the panel remains stable and will not easily loosen or detach. The evenly spaced distribution of multiple first clamping parts makes the lower part of the panel more balanced when subjected to force, and each clamping part shares the external force together, avoiding deformation or damage caused by excessive local force, and further improving the reliability and stability of the connection.

[0017] Furthermore, the first clamping portion is a buckle, the second clamping portion is a socket, and at least one of the buckle and the socket is configured to be elastic.

[0018] The aforementioned technical solution utilizes an elastic design that makes the connection between the buckle and the base more flexible. During installation, simply align the buckle with the base and gently press. Due to its elasticity, the buckle can be smoothly snapped into the base, enabling quick installation. During removal, the buckle can also be ejected from the base with appropriate external force, making operation simple and convenient. The elastic buckle and base can better adapt to different dimensional tolerances and installation errors. Even if there are some minor dimensional differences during the manufacturing process, the elastic component can adjust through its own deformation, ensuring a tight fit between the buckle and the base, preventing loosening and falling off.

[0019] Furthermore, among the multiple buckles, the elastic deformation direction of at least one of the buckles is the left-right direction, and the elastic deformation direction of at least one of the buckles is the up-down direction; or, the elastic deformation direction of at least one of the sockets is the left-right direction, and the elastic deformation direction of at least one of the sockets is the up-down direction.

[0020] By adopting the above-mentioned technical solution, by setting buckles or sockets with different elastic deformation directions, the entire casing can better adapt to external forces from different directions. When subjected to external forces in the left and right directions, the buckles or sockets with elastic deformation directions in the left and right directions can play a buffering role and reduce the impact on the connection parts; similarly, when subjected to external forces in the up and down directions, the buckles or sockets with elastic deformation directions in the up and down directions play a role, which can effectively improve the stability of the connection between the panel and the middle frame and reduce the risk of loosening or damage caused by external forces. The multi-directional elastic design can disperse external forces to different buckles or sockets to avoid stress concentration in a certain part, which can reduce the burden of a single buckle or socket and improve the reliability and durability of the entire connection structure.

[0021] Furthermore, the hinge structure between the panel and the middle frame is provided between the first clamping portion and the third clamping portion.

[0022] By adopting the above-mentioned technical solution, the hinge structure between the panel and the middle frame is arranged between the first clamping part and the third clamping part, so that the force distribution of the entire panel is more reasonable when it is connected to the middle frame. The hinge structure is an important connection point, and the choice of its position can affect the stability of the panel during the opening and closing process. By arranging it between the first clamping part and the third clamping part, the force in the upper and lower directions can be effectively balanced, reducing the deformation or damage of the panel caused by uneven force.

[0038] The following specific embodiments are used to describe the technical solution of the present application in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0039] like Figures 1 to 10 As shown, the present application provides an air-conditioner inner unit casing, comprising a middle frame 1 and a panel 2 arranged on the front side of the middle frame 1, the upper part of the panel 2 is hinged to the upper part of the middle frame 1, the lower part of the panel 2 is provided with a first clamping portion 21, the lower part of the middle frame 1 is provided with a second clamping portion 11 adapted to and clamped with the first clamping portion 21, the upper edge of the panel 2 is provided with a third clamping portion 22, and the middle frame 1 is provided with a fourth clamping portion 12 adapted to and clamped with the third clamping portion 22.

[0040] After adopting the above technical solution, the present application has the following advantages: by setting a third clamping portion 22 on the upper edge of the panel 2 and setting a corresponding fourth clamping portion 12 on the middle frame 1, the upper edge of the panel 2 is still not easy to warp after the air conditioner is used for a long time and undergoes multiple repairs and disassemblies, thereby ensuring the aesthetics of the air conditioner. Moreover, since the lower part of the panel 2 is provided with a first clamping portion 21 and the corresponding lower part of the middle frame 1 is provided with a second clamping portion 11, the lower part of the panel 2 is also kept flat without warping, making the air conditioner more beautiful and integrated as a whole.

[0041] Furthermore, when the panel 2 covers the front side of the middle frame 1 , the panel 2 shields the third clamping portion 22 and the fourth clamping portion 12 .

[0042] By adopting the above-mentioned technical solution, firstly, through the hidden design, when the panel 2 is covered on the front side of the middle frame 1, the third clamping part 22 and the fourth clamping part 12 can be shielded, so that the air conditioner inner shell presents a simple and smooth appearance, which is more integrated with the interior decoration environment and enhances the overall coordination. Secondly, in terms of protecting the clamping part, the clamping part is avoided from being directly exposed to the outside to reduce wear and tear, and at the same time, dust accumulation is prevented, the service life of the clamping part is extended, the stability of the connection between the panel 2 and the middle frame 1 is ensured, and the difficulty of cleaning and maintenance is reduced.

[0043] Furthermore, the fourth engaging portion 12 is an upwardly opening engaging slot, and the third engaging portion 22 is a downwardly protruding engaging protrusion. When the panel 2 covers the front side of the middle frame 1, the engaging protrusion extends from top to bottom into the engaging slot and engages with the engaging slot.

[0044] By adopting the above-mentioned technical solution, the cooperation between the protrusion and the groove can provide a strong connecting force. The gravity of the panel 2 can make the third clamping part 22 clamped in the fourth clamping part 12, ensuring that the panel 2 will not be easily loosened or detached during long-term use. In the front and rear directions, the third clamping part 22 limits the fourth clamping part 12, preventing the upper edge of the panel 2 from bulging outward and warping due to opening and closing, making the appearance of the panel 2 more beautiful.

[0045] Furthermore, a reinforcing rib 3 is provided on the top edge of the back side of the panel 2 , and the third clamping portion 22 is fixed to the lower end surface of the reinforcing rib 3 .

[0046] The aforementioned technical solution, in which reinforcing ribs 3 are provided on the top edge of the back side of panel 2, does not affect the appearance of the air conditioner's indoor unit while significantly enhancing the structural strength of panel 2. Ribs 3 disperse external forces acting on panel 2, reducing the risk of deformation and damage during use. Especially when panel 2 is frequently opened and closed for filter changes, ribs 3 ensure that panel 2 remains flat and is less susceptible to warping or deformation.

[0047] Furthermore, there are multiple third clamping portions 22 , which are spaced apart along the left-right direction, and the fourth clamping portions 12 are disposed in a one-to-one correspondence with the third clamping portions 22 .

[0048] By adopting the above-mentioned technical solution, multiple third clamping parts 22 are evenly spaced along the left and right directions, and cooperate with the corresponding fourth clamping parts 12 to achieve multi-point fixation. This multi-point fixation method can form a more secure connection between the panel 2 and the middle frame 1, effectively preventing the panel 2 from loosening, warping and other problems during long-term use. The uniform distribution of multiple clamping parts enables the panel 2 to be evenly stressed when subjected to external force, avoiding deformation or damage caused by excessive local force.

[0049] Specifically, the third clamping portions 22 are arranged in a uniform distribution.

[0050] Furthermore, there are multiple first clamping portions 21 , which are spaced apart along the left-right direction, and the second clamping portions 11 and the first clamping portions 22 are disposed in a one-to-one correspondence.

[0051] By adopting the above-mentioned technical solution, multiple first clamping parts 21 are arranged at intervals along the left and right directions, and cooperate with the corresponding second clamping parts 11 to achieve multi-point clamping. This multi-point clamping method greatly enhances the connection firmness between the lower part of the panel 2 and the middle frame 1. During the use of the air conditioner, no matter whether it is affected by vibration, external force impact or long-term opening and closing, it can ensure that the lower part of the panel 2 remains stable and will not easily become loose or detached. The uniformly spaced distribution of multiple first clamping parts 21 makes the lower part of the panel 2 more balanced when subjected to force, and each clamping part shares the external force together, avoiding deformation or damage caused by excessive local force, and further improving the reliability and stability of the connection.

[0052] Specifically, the first clamping portions 21 are arranged in a uniform distribution.

[0053] Furthermore, the first clamping portion 21 is a buckle, the second clamping portion 11 is a socket, and at least one of the buckle and the socket is configured to be elastic.

[0054] The aforementioned technical solution utilizes an elastic design that makes the connection between the buckle and the base more flexible. During installation, simply align the buckle with the base and gently press. Due to its elasticity, the buckle can be smoothly snapped into the base, enabling quick installation. During removal, the buckle can also be ejected from the base with appropriate external force, making operation simple and convenient. The elastic buckle and base can better adapt to different dimensional tolerances and installation errors. Even if there are some minor dimensional differences during the manufacturing process, the elastic component can adjust through its own deformation, ensuring a tight fit between the buckle and the base, preventing loosening and falling off.

[0055] Furthermore, among the multiple buckles, such as Figure 9 As shown, the elastic deformation direction of at least one of the buckles is left and right, as shown in FIG. Figure 8 As shown, the elastic deformation direction of at least one of the buckles is the up-down direction; or, as Figure 7 As shown, the elastic deformation direction of at least one of the holders is left-right, as shown in FIG. Figure 6 As shown, the elastic deformation direction of at least one of the holders is in the up-down direction.

[0056] By adopting the above-mentioned technical solution, by setting buckles or sockets with different elastic deformation directions, the entire casing can better adapt to external forces from different directions. When subjected to external forces in the left and right directions, the buckles or sockets with elastic deformation directions in the left and right directions can play a buffering role and reduce the impact on the connection parts; similarly, when subjected to external forces in the up and down directions, the buckles or sockets with elastic deformation directions in the up and down directions play a role, which can effectively improve the stability of the connection between the panel 2 and the middle frame 1 and reduce the risk of loosening or damage caused by external forces. The multi-directional elastic design can disperse external forces to different buckles or sockets to avoid stress concentration in a certain part, which can reduce the burden of a single buckle or socket and improve the reliability and durability of the entire connection structure.

[0057] Specifically, in the buckle structure in the up and down directions, the base on the middle frame 1 is as follows: Figure 6 As shown, a blocking block 5 is provided in the relative direction to prevent the buckle on the panel 2 from being excessively deformed, thereby preventing the panel 2 from being deformed, and the thickness of the socket on the middle frame 1 is thinner than the thickness of the buckle on the panel 2.

[0058] Furthermore, the hinge structure 4 between the panel 2 and the middle frame 1 is provided between the first clamping portion 21 and the third clamping portion 22 .

[0059] By adopting the above-mentioned technical solution, the hinge structure 4 between the panel 2 and the middle frame 1 is arranged between the first clamping portion 21 and the third clamping portion 22, so that the force distribution of the entire panel 2 is more reasonable when it is connected to the middle frame 1. The hinge structure 4 is an important connection point, and the choice of its position can affect the stability of the panel 2 during the opening and closing process. By arranging it between the first clamping portion 21 and the third clamping portion 22, the forces in the upper and lower directions can be effectively balanced, reducing the deformation or damage of the panel 2 caused by uneven force.

[0060] Specifically, the hinge seat 42 in the hinge structure 4 is arranged between the first clamping part 21 and the third clamping part 22 in the up and down directions, and the hinge seat 42 on the panel 2 is an L-shaped rotating block, the hinge connection is at one end of the L-shape, and the fixation with the panel 2 is at the other end of the L-shape.

[0061] Preferably, a longitudinal beam 13 is provided on the side of the middle frame 1 facing the panel 2. The longitudinal beam 13 is close to the frame on one side, and a hinge head 41 in one hinge structure 4 is provided on the longitudinal beam 13. Two protrusions 23 are provided on the back of the panel 2 to abut against the longitudinal beam 13.

[0062] The advantage of this preferred solution is that the longitudinal beam 13 increases the structural strength of the middle frame 1, and the position of the hinge head 41 in the hinge structure 4 is shifted to the middle, so that the hinge strength of the panel 2 is improved. The protrusion 23 is provided on the back of the panel 2. On the one hand, it is used to adjust the distance between the longitudinal beam 13 and the panel 2, and on the other hand, it is used to avoid direct contact between the middle frame 1 and the longitudinal beam 13, thereby reducing the collision with the middle frame 1 when the panel 2 is covered.

[0063] Preferably, a clamping beam 14 is provided between the two hinged joints 41 of the middle frame 1 , and a corresponding clamping joint 24 for clamping on the clamping beam is provided on the panel 2 , and is flush with the hinge structure 4 in the vertical direction.

[0064] An air conditioner indoor unit includes the above-mentioned shell, wherein the top of the shell is provided with an air inlet, the air inlet is provided with a filter, the bottom of the shell is provided with an air outlet, the air outlet is provided with an air guide plate, and the shell is provided with an evaporator, a fan and an electric control box.

[0065] In addition to the above-mentioned preferred embodiments, the present application also has other implementation methods. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present application.
