Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to an air conditioner. Background Technology

[0002] During long-term operation, dust, bacteria, and pollutants can easily accumulate on the air intake grille and the surface of the internal evaporator of an air conditioner, affecting heat exchange efficiency, air quality, and equipment performance. Therefore, regular cleaning is an important maintenance measure to ensure the normal operation of the air conditioner.

[0003] However, in many current air conditioner designs, the air intake area and internal heat exchange components are entirely enclosed within the outer casing panel. Users or maintenance personnel must first disassemble the entire front casing panel before cleaning, sometimes requiring tools to loosen multiple screws or clips to expose the filter and evaporator. This process is not only cumbersome and time-consuming, but also difficult for non-professional users, easily leading to broken panel clips or improper installation, affecting the overall sealing and aesthetics of the unit. Furthermore, frequent disassembly of the casing may affect the stability of the air conditioner structure, increasing safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide an air conditioner that significantly improves the convenience of cleaning and even maintaining the interior of the air conditioner, and helps to extend the service life of the air conditioner.

[0005] The embodiments of this utility model are implemented as follows: In a first aspect, this utility model provides an air conditioner, comprising: The outer casing has cleaning holes on any and at least one wall surface. A cover plate, detachably disposed on the housing, the cover plate being used to open or cover the cleaning hole, the outer wall of the cover plate being provided with at least two grooves to form a screw portion between the at least two grooves.

[0006] In the above embodiments, by providing cleaning holes on any and at least one wall surface of the outer casing, and providing a removable cover plate at the cleaning holes, it is possible to clean, repair, or replace parts inside the air conditioner through the cleaning holes without disassembling the entire outer casing panel, thereby improving the convenience and practicality of operation. The cover plate forms a screwing part through at least two grooves on its outer wall, allowing the user to insert their fingers into the grooves and apply screwing force to the screwing part, thus achieving a detachable connection between the cover plate and the outer casing. This simplifies the disassembly and assembly process of the cover plate, and the opening and closing of the cover plate can be completed without additional tools, further improving the convenience and efficiency of operation. In addition, by providing at least two grooves on the outer wall of the cover plate to form a screwing part, the cover plate structure can be prevented from protruding from the outer casing wall when the cover plate is placed over the cleaning hole, thereby making the outer casing surface of the air conditioner flat and achieving a unified appearance in terms of visual and tactile senses. This reduces the possibility of the cover plate being accidentally loosened by collision, which not only facilitates transportation but also improves aesthetics.

[0007] In an optional embodiment, the outer shell is provided with a first retaining part, and the inner wall of the cover plate is provided with a second retaining part, wherein the first retaining part and the second retaining part can be engaged when the cover plate is twisted.

[0008] In the above embodiment, when the user aligns the cover with the cleaning hole and applies a screwing force, the second retaining part on the inner wall of the cover moves relative to the first retaining part on the outer shell and is inserted into the corresponding mating position after being screwed in place, thereby achieving the locking and fixing of the cover with the outer shell, thus ensuring that the cover will not loosen due to vibration or external force when not disassembled, thereby improving the reliability of the connection between the outer shell and the cover.

[0009] In an optional embodiment, the first holding part is a through hole, and the second holding part is a buckle.

[0010] In the above embodiments, the use of through holes and snap-fits as the snap-fit ​​method not only meets the functional requirements of quick disassembly and assembly of the cover plate, but also ensures its structural strength in the installed state, significantly improving assembly efficiency, reducing production costs, and enhancing user operation convenience.

[0011] In an optional embodiment, there are multiple first retaining parts and multiple second retaining parts. The multiple first retaining parts are arranged around the cleaning hole, and the multiple second retaining parts are engaged with the multiple first retaining parts in a corresponding manner.

[0012] In the above embodiment, multiple first retaining parts are arranged in a ring around the cleaning hole, making the force in all directions more uniform during the screwing and clamping process of the cover plate, avoiding deformation or damage that may be caused by local stress concentration. Multiple second retaining parts provided on the inner wall of the cover plate correspond one-to-one with the aforementioned first retaining parts, ensuring that after screwing in place, the cover plate can achieve a stable connection with the outer shell through multi-point clamping. This not only improves the stability of the cover plate installation but also effectively prevents the risk of the cover plate falling off due to single-point failure, thereby improving the reliability of the overall structure.

[0013] In an optional embodiment, the outer casing is provided with a mounting groove, the mounting groove is circumferentially disposed around the cleaning hole, the first retaining part is disposed on the bottom wall of the mounting groove, the shape of the mounting groove is adapted to the shape of the cover plate, and the cover plate is disposed in the mounting groove so that the outer wall surface of the cover plate is flush with the wall surface of the outer casing.

[0014] In the above embodiments, the mounting groove provides a clearly defined mounting and positioning area for the cover plate, enabling the cover plate to be stably embedded in the mounting groove of the outer shell during screwing, thereby avoiding installation misalignment. The first retaining part is provided on the bottom wall of the mounting groove, providing an accurate mating position for the second retaining part on the inner wall of the cover plate, ensuring smooth engagement.

[0015] In an optional embodiment, the air conditioner further includes a fastener, the outer casing is provided with a first mounting hole, the cover plate is provided with a second mounting hole, and when the first retaining part is engaged with the first retaining part, the first mounting hole and the second mounting hole correspond to each other, and the fastener passes through the first mounting hole and the second mounting hole.

[0016] In the above embodiment, the first mounting hole is provided on the outer shell, and the second mounting hole is provided on the cover plate. The cover plate and the outer shell are aligned perfectly when they are snapped together. At this time, fasteners are inserted through the first and second mounting holes to further enhance the connection strength and structural stability on the basis of the original snap-fit ​​structure.

[0017] In an optional embodiment, the outer wall of the cover plate is further provided with a marking portion, which is used to indicate the screwing direction for disassembling the cover plate from the housing.

[0018] In the above embodiments, when the user needs to disassemble the cover plate, the marking part clearly indicates the turning direction on the outer wall of the cover plate, ensuring that the user can intuitively identify the correct disassembly path, avoiding the application of reverse force due to misoperation, and thus preventing assembly difficulties or even structural damage due to incorrect turning direction.

[0019] In an optional embodiment, the air conditioner further includes an evaporator disposed inside the housing, and the cleaning port is located on one side of the evaporator corresponding to the air intake area.

[0020] In the above embodiment, the cleaning port is located on one side of the evaporator corresponding to the air inlet area. This allows for easy access to the evaporator area for cleaning or maintenance by removing the cover plate. This optimizes the accessibility of the cleaning path and improves maintenance efficiency without altering the overall structure of the air conditioner.

[0021] In an optional embodiment, the housing is further provided with an air outlet, the evaporator is inclinedly disposed on the housing, and the cleaning hole is disposed on the side plate of the housing and located near the inlet of the longitudinal air inlet area corresponding to the evaporator.

[0022] In the above embodiment, since the evaporator is inclined, the air intake area enclosed between the evaporator and the outer shell has a spatial structure that is smaller at the top and larger at the bottom. The inlet corresponding to the air intake area has the greatest heat exchange, resulting in the most severe dirt blockage. Therefore, the cleaning hole is set on the evaporator near the inlet of the longitudinal air intake area close to the fan, so that the operator can easily reach into the cleaning hole to clean the evaporator. In addition, since the space below the evaporator is large, it is more convenient for tools or cleaning media to directly act on the surface of the evaporator during cleaning operations, without being blocked by structures or components such as the air outlet channel.

[0023] In an optional embodiment, the evaporator is flat. In the above embodiments, the flat evaporator makes the internal structure of the air conditioner more compact, avoids occupying a large space inside the air conditioner, and the flat structure has good rigidity and compressive strength, and is not easily deformed by external forces.

[0024] The beneficial effects of the air conditioner provided by this utility model embodiment include: by providing a cleaning hole on any and at least one wall surface of the outer casing, and providing a removable cover plate at the cleaning hole, it is possible to clean, repair, or replace parts inside the air conditioner through the cleaning hole without disassembling the entire outer casing panel, thereby improving the convenience and practicality of operation; the cover plate forms a screwing part through at least two grooves on its outer wall, so that the user can insert their fingers into the grooves and apply screwing force to the screwing part, so that the cover plate and the outer casing can be detachably connected, thereby simplifying the disassembly and assembly process of the cover plate, and the opening and closing of the cover plate can be completed without additional tools, further improving the convenience and efficiency of operation; in addition, by providing at least two grooves on the outer wall of the cover plate to form a screwing part, the cover plate structure can be prevented from protruding from the outer casing wall surface when the cover plate is placed on the cleaning hole, thereby making the outer casing surface of the air conditioner flat, achieving an integrated appearance effect in terms of vision and touch, reducing the possibility of the cover plate being accidentally loosened by collision, which not only facilitates transportation but also improves aesthetics.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] During long-term operation, dust, bacteria, and pollutants can easily accumulate on the air intake grille and the surface of the internal evaporator of an air conditioner, affecting heat exchange efficiency, air quality, and equipment performance. Therefore, regular cleaning is an important maintenance measure to ensure the normal operation of the air conditioner.

[0035] However, in many current air conditioner designs, the air intake area and internal heat exchange components are entirely enclosed within the outer casing panel. Users or maintenance personnel must first disassemble the entire front casing panel before cleaning, sometimes requiring tools to loosen multiple screws or clips to expose the filter and evaporator. This process is not only cumbersome and time-consuming, but also difficult for non-professional users, easily leading to broken panel clips or improper installation, affecting the overall sealing and aesthetics of the unit. Furthermore, frequent disassembly of the casing may affect the structural stability of the air conditioner, increasing safety hazards.

[0036] Therefore, there is an urgent need to provide an air conditioner structure that is easy to clean, in order to solve the problem that the existing technology requires the complete disassembly of the outer shell panel and is complicated to operate, thereby improving the convenience of cleaning and user experience, and promoting the standardized maintenance and long-term stable operation of air conditioning equipment.

[0037] Please see Figures 1 to 5 This utility model provides an air conditioner 10, which includes a housing 100 and a cover plate 200.

[0038] In detail, a cleaning hole 110 is provided on any and at least one wall surface of the housing 100, and a cover plate 200 is detachably provided on the housing 100. The cover plate 200 is used to open or cover the cleaning hole 110, and the outer wall of the cover plate 200 is provided with at least two grooves 210 to form a screw portion 220 between the at least two grooves 210.

[0039] In this embodiment, by providing a cleaning hole 110 on any and at least one wall surface of the outer casing 100, and providing a removable cover plate 200 at the cleaning hole 110, it is possible to clean, repair or replace parts inside the air conditioner 10 through the cleaning hole 110 without disassembling the entire outer casing 100 panel, thereby improving the convenience and practicality of operation.

[0040] The cover plate 200 forms a screwing part 220 through at least two grooves 210 on its outer wall, so that the user can insert his / her fingers into the grooves 210 and apply screwing force to the screwing part 220 to achieve a detachable connection between the cover plate 200 and the outer shell 100. This simplifies the disassembly and assembly process of the cover plate 200, and the opening and closing of the cover plate 200 can be completed without additional tools, further improving the convenience and efficiency of operation.

[0041] Furthermore, by providing at least two grooves 210 on the outer wall of the cover plate 200 to form a screw-in portion 220, the cover plate 200 can be prevented from protruding from the wall of the outer casing 100 when it is placed over the cleaning hole 110. This makes the surface of the outer casing 100 of the air conditioner 10 flat, achieving an integrated appearance in terms of both visual appeal and tactile feel. It also reduces the possibility of the cover plate 200 being accidentally knocked off, which not only facilitates transportation but also improves aesthetics.

[0042] It is understandable that the location of the cleaning port 110 can be flexibly selected according to the actual installation environment, allowing users to choose the cleaning path that is most convenient to operate according to actual usage needs, thereby improving the maintainability of the equipment.

[0043] Therefore, the air conditioner 10 provided by this utility model embodiment significantly improves the convenience of cleaning and even maintaining the interior of the air conditioner 10, and helps to extend the service life of the air conditioner 10.

[0044] Furthermore, the outer shell 100 is provided with a first retaining part 120, and the inner wall of the cover plate 200 is provided with a second retaining part 230. The first retaining part 120 and the second retaining part 230 can be engaged when the cover plate 200 is twisted.

[0045] Specifically, when the user aligns the cover plate 200 with the cleaning hole 110 and applies a screwing force, the second retaining part 230 on the inner wall of the cover plate 200 moves relative to the first retaining part 120 provided on the outer shell 100, and after being screwed into place, it is inserted into the corresponding mating position, thereby realizing the snap-fit ​​fixation between the cover plate 200 and the outer shell 100, thus ensuring that the cover plate 200 will not loosen due to vibration or external force in the non-disassembly state, thereby improving the connection reliability between the outer shell 100 and the cover plate 200.

[0046] In detail, the first holding part 120 is a through hole and the second holding part 230 is a buckle. Therefore, the combination of through hole and buckle is adopted as the snap-fit ​​method, which not only meets the functional requirements of quick disassembly and assembly of cover plate 200, but also ensures its structural strength in the installed state, significantly improving assembly efficiency, reducing production costs and enhancing user operation convenience.

[0047] Of course, in other embodiments of this utility model, the first holding part 120 may be a buckle and the second holding part 230 may be a through hole, as long as the first holding part 120 and the second holding part 230 can be engaged, and no specific limitation is made here.

[0048] It should be noted that there are multiple first holding parts 120 and multiple second holding parts 230. Multiple first holding parts 120 are arranged in a ring around the cleaning hole 110, and multiple second holding parts 230 are engaged with the multiple first holding parts 120 in a one-to-one correspondence.

[0049] Multiple first retaining parts 120 are arranged in a ring around the cleaning hole 110, making the force in all directions more uniform during the screwing and clamping process of the cover plate 200, thus avoiding deformation or damage that may be caused by local stress concentration. Multiple second retaining parts 230 provided on the inner wall of the cover plate 200 correspond one-to-one with the aforementioned first retaining parts 120, ensuring that after screwing in place, the cover plate 200 can achieve a stable connection with the outer shell 100 through multi-point clamping. This not only improves the stability of the cover plate 200 installation but also effectively prevents the risk of the cover plate 200 falling off due to single-point failure, thereby improving the overall structural reliability.

[0050] Furthermore, the outer casing 100 is provided with a mounting groove 130, which is arranged around the cleaning hole 110. The first holding part 120 is provided on the bottom wall of the mounting groove 130. The shape of the mounting groove 130 is adapted to the shape of the cover plate 200. The cover plate 200 is disposed in the mounting groove 130 so that the outer wall surface of the cover plate 200 is flush with the wall surface of the outer casing 100.

[0051] As can be seen, in this embodiment, the mounting groove 130 provides a clear mounting and positioning area for the cover plate 200, enabling the cover plate 200 to be stably embedded in the mounting groove 130 of the outer shell 100 during the screwing process, thereby avoiding installation misalignment. The first retaining part 120 is disposed on the bottom wall of the mounting groove 130, providing an accurate mating position for the second retaining part 230 on the inner wall of the cover plate 200, ensuring smooth engagement.

[0052] Furthermore, since the cover plate 200 is ultimately embedded in the mounting groove 130 and adapted to its shape, its outer wall will not protrude from the wall of the outer shell 100, thus presenting an integrated appearance in terms of both visual appeal and tactile feel. This reduces the possibility of the cover plate 200 being accidentally knocked off and also reduces the risk of dust accumulation.

[0053] Furthermore, the air conditioner 10 also includes a fastener 300. The outer casing 100 is provided with a first mounting hole 140, and the cover plate 200 is provided with a second mounting hole 240. When the first holding part 120 is engaged with the first holding part 120, the first mounting hole 140 and the second mounting hole 240 correspond to each other, and the fastener 300 passes through the first mounting hole 140 and the second mounting hole 240.

[0054] In this embodiment, the first mounting hole 140 is provided on the outer shell 100, and the second mounting hole 240 is provided on the cover plate 200. The cover plate 200 and the outer shell 100 are aligned when they are snapped together. At this time, the fasteners 300 are inserted through the first mounting hole 140 and the second mounting hole 240, thereby further enhancing the connection strength and structural stability on the basis of the original snap-fit ​​structure.

[0055] Optionally, the fastener 300 can be a screw. Of course, in other embodiments of this utility model, the fastener 300 can also be other components, which are not specifically limited here.

[0056] Furthermore, the outer wall of the cover plate 200 is also provided with a marking part 250, which is used to indicate the screwing direction for disassembling the cover plate 200 from the outer casing 100.

[0057] In this embodiment, the marking part 250 is an arrow symbol. Therefore, when the user needs to disassemble the cover plate 200, the marking part 250 clearly marks the turning direction on the outer wall of the cover plate 200, ensuring that the user can intuitively identify the correct disassembly path, avoid applying reverse force due to misoperation, and thus prevent assembly difficulties or even structural damage due to incorrect turning direction.

[0058] Furthermore, the air conditioner 10 also includes an evaporator 400, which is disposed inside the housing 100, and a cleaning hole 110 is located on one side of the evaporator 400 corresponding to the air intake area.

[0059] In this embodiment, the cleaning hole 110 is arranged on one side of the evaporator 400 corresponding to the air inlet area, so that when the evaporator 400 needs to be cleaned or maintained, the cleaning hole 110 can be exposed by removing the cover plate 200, and the evaporator 400 area can be accessed to carry out the cleaning operation. This optimizes the accessibility of the cleaning path and improves maintenance efficiency without changing the overall structure of the air conditioner 10.

[0060] In detail, the housing 100 is also provided with an air outlet 150, the evaporator 400 is inclinedly disposed on the housing 100, and the cleaning hole 110 is disposed on the side plate of the housing 100 and located near the inlet of the longitudinal air inlet area corresponding to the evaporator 400.

[0061] In this embodiment, since the evaporator 400 is inclined, the air inlet area enclosed between the evaporator 400 and the outer casing 100 has a spatial structure that is smaller at the top and larger at the bottom. The inlet corresponding to the air inlet area has the largest heat exchange, resulting in the most severe dirt blockage. Therefore, the cleaning hole 110 is set on the evaporator 400 near the inlet of the longitudinal air inlet area close to the fan, so that the operator can easily put his hand into the cleaning hole 110 to clean the evaporator 400. In addition, since the space below the evaporator is large, it is more convenient for tools or cleaning media to directly act on the surface of the evaporator 400 during cleaning operations, without being blocked by structures or components such as the air outlet 150.

[0062] Specifically, the cleaning hole 110 is provided on the side panel of the housing 100.

[0063] In this embodiment, the cleaning hole 110 is located on the side panel of the housing 100, allowing the cleaning operation to be performed directly through the side while the air conditioner 10 is installed, without the need to move the air conditioner 10 significantly or remove other structural components, thereby improving maintenance efficiency. Furthermore, the side panel is away from the air inlet and outlet paths, and placing the cleaning hole 110 there also helps to avoid interference from airflow structures or components during the cleaning process.

[0064] Of course, in other embodiments of this utility model, the cleaning hole 110 may also be provided in at least one of the back plate, front plate or top plate, and each plate wall is provided with at least one cleaning hole 110, and each cleaning hole 110 is provided with a cover plate 200.

[0065] It is worth mentioning that the evaporator 400 is flat.

[0066] It is understandable that the flat evaporator 400 makes the internal structure of the air conditioner 10 more compact, avoiding taking up a large amount of internal space. In addition, the flat structure has good rigidity and compressive strength, and is not easily deformed by external forces.

[0067] In summary, this utility model provides an air conditioner 10. By providing a cleaning hole 110 on any and at least one wall surface of the outer casing 100, and providing a removable cover plate 200 at the cleaning hole 110, it is possible to clean, repair, or replace parts inside the air conditioner 10 through the cleaning hole 110 without disassembling the entire outer casing 100 panel, thus improving the convenience and practicality of operation. The cover plate 200 forms a screwing part 220 through at least two grooves 210 on its outer wall, so that the user can insert his / her fingers into the grooves 210 and apply screwing force to the screwing part 220 to make the cover plate 200 and the outer casing 100 securely fastened. The detachable connection simplifies the disassembly and assembly process of the cover 200, and the cover 200 can be opened and closed without additional tools, further improving the convenience and efficiency of operation. In addition, by providing at least two grooves 210 on the outer wall of the cover 200 to form a screw part 220, the cover 200 structure can be prevented from protruding from the wall of the outer casing 100 when it covers the cleaning hole 110, thereby making the surface of the outer casing 100 of the air conditioner 10 flat and achieving an integrated appearance in terms of visual and tactile senses. This reduces the possibility of the cover 200 being accidentally knocked off, which not only facilitates transportation but also improves aesthetics.

[0068] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
