[0045] When repairing or replacing core components such as fans and motors in existing embedded air conditioner indoor units, it is often necessary to first perform an air intake operation on the air conditioning system, that is, recover or discharge the refrigerant, to avoid harm to the environment and the human body caused by refrigerant leakage. Subsequently, the entire air conditioning unit also needs to be removed from the cabinet to perform specific repair or replacement operations.

[0046] The present utility model provides an air conditioner indoor unit 10 and a cabinet 20, aiming to solve the problem of inconvenient maintenance of the motor 150 and the air supply fan 140 of the existing air conditioner indoor unit 10.

[0047] Air conditioners are usually divided into single-unit air conditioners with all components installed in one body and split air conditioners with all components separately installed in indoor and outdoor units. In the following description, the embodiments of the present utility model described are for split air conditioners. In addition, the air conditioner indoor unit 10 of the present utility model is equipped with an outdoor unit in the same form as a common outdoor unit, and the description of the outdoor unit part is omitted below.

[0048] Figure 1 It is a schematic structural diagram of an air conditioner indoor unit 10 in which the air inlet 101 is in a closed state according to an embodiment of the present utility model. Figure 2Schematic structural diagram of an air conditioner indoor unit 10 with the air inlet 101 in an open state according to an embodiment of the present invention. Figure 3 Schematic exploded view of an air conditioner indoor unit 10 according to an embodiment of the present invention. Figure 4 Schematic cross-sectional view of an air conditioner indoor unit 10 according to an embodiment of the present invention.

[0049] Referring to Figures 1 to 4 , the air conditioner indoor unit 10 of the present invention mainly includes a housing 100, a heat exchanger 130, a blower fan 140, and a motor 150.

[0050] Among them, the housing 100 can accommodate different components for the operation of the indoor unit, including the heat exchanger 130, the blower fan 140, the motor 150, etc. An air inlet 101 and an air outlet 102 are provided on the front side of the housing 100, and the air inlet 101 is located above the air outlet 102. This layout allows the indoor unit to intake air from the front upper part and discharge air from the front lower part.

[0051] When the indoor unit needs to be installed in a limited space such as a cabinet 20, the way of intake air from the front upper part and discharge air from the front lower part shows its unique advantages. Since both the air inlet 101 and the air outlet 102 are located on the front side of the housing 100 and are not restricted by the top plate 210 and the bottom plate 220 of the cabinet 20, there is no need to worry about air flow obstruction or insufficient space, which greatly improves the installation flexibility and adaptability of the indoor unit.

[0052] The shape of the housing 100 can be rectangular, and both the air inlet 101 and the air outlet 102 are long strip openings extending along the transverse direction of the housing 100. On the one hand, the front side space of the housing 100 can be fully utilized, so that the air inlet 101 and the air outlet 102 occupy a larger area, thereby improving the air flow efficiency. On the other hand, the long strip opening is also beneficial to the uniform distribution of air, avoiding the problem of excessive or insufficient air volume in a local area.

[0053] The air intake area of the air inlet 101 is larger than the air outlet area of the air outlet 102. In this way, even if the air velocity at the air inlet 101 is relatively low, it can ensure that there is enough air volume entering the indoor unit. After being heated or cooled by the heat exchanger 130, it is then discharged from the air outlet 102 at a higher air velocity. At the same time, due to the larger area of the air inlet 101, the local air velocity at the air inlet 101 can also be reduced, reducing noise and vibration, and improving the comfort and stability of the indoor unit.

[0054] For example, the left - right length of the air inlet 101 is equal to the left - right length of the air outlet 102, and the up - down height of the air inlet 101 is greater than the up - down height of the air outlet 102, which can ensure that the air intake area of the air inlet 101 is larger than the air outlet area of the air outlet 102.

[0055] In an alternative embodiment, the housing 100 may be composed of two parts, namely a rear housing 110 and a front frame 120. Among them, the front side of the rear housing 110 is open, facilitating the direct installation of components such as the heat exchanger 130, the air supply fan 140, and the motor 150 into its interior. The front frame 120 is used to cover the open front side of the rear housing 110, and it is detachably connected to the rear housing 110 through fasteners.

[0056] During the process of installing the indoor unit in the cabinet 20, the rear housing 110 of the indoor unit can be installed first, and then the front frame 120 can be installed on the rear housing 110. This method reduces the complexity of on-site installation and improves the installation efficiency. When a fault occurs in the indoor unit, only by removing the front frame 120 can one directly access the exposed components for necessary inspection and repair work.

[0057] In an alternative embodiment, the front frame 120 includes a main frame body 121 and a front panel 122. Among them, the air inlet 101 is opened in the upper region of the main frame body 121, and the air outlet 102 is opened in the lower region of the main frame body 121. The lower end of the front panel 122 is pivotally installed on the main frame body 121 and is configured to be controllably turned up and down around the pivot point to open or close the air inlet 101.

[0058] It can be understood that during the use of the indoor unit, if the air flow between the air inlet 101 and the air outlet 102 is not properly isolated and guided, the situation of air leakage may occur, that is, the cold air and the hot air are mixed with each other inside the housing 100, resulting in a reduction in the heat exchange efficiency and even affecting the uniformity of the indoor temperature.

[0059] In the above embodiment, when the front panel 122 is turned forward and opened, the front panel 122 can serve as a barrier for guiding the air flow, ensuring that the cold air or hot air entering from the air inlet 101 can flow along a predetermined path, and after being heat-exchanged by the heat exchanger 130, it is then discharged from the air outlet 102. At the same time, the front panel 122 can also block the air discharged from the air outlet 102 from directly flowing back to the air inlet 101, effectively avoiding the problem of air leakage.

[0060] An air inlet grille 123 may be provided at the air inlet 101, and the air inlet grille 123 is formed by the intersection of a plurality of longitudinal ribs and transverse ribs.

[0061] The introduction of the air inlet grille 123 is crucial for guiding the air flow. The staggered arrangement of the longitudinal ribs and the transverse ribs forms an orderly grid structure, which can effectively disperse and guide the incoming air flow, reducing the occurrence of eddy currents and turbulence phenomena. This not only improves the stability of the air flow but also ensures that the air can be evenly distributed to each part of the heat exchanger 130, thereby improving the heat exchange efficiency.

[0062] The design of the air inlet grille 123 also takes into account the structural strength of the main housing 121. By increasing the number and density of the longitudinal ribs and transverse ribs, the overall structure of the main housing 121 is strengthened. This enhanced design makes the main housing 121 more stable when withstanding external pressure and impact, reducing the risk of deformation and damage. At the same time, the air inlet grille 123 itself also serves as a part of the main housing 121, sharing part of the load and further improving the structural strength and durability of the entire indoor unit.

[0063] The heat exchanger 130 is disposed within the housing 100 and is located on the airflow path between the air inlet 101 and the air outlet 102. The heat exchanger 130 mainly exchanges heat between, for example, the refrigerant flowing inside it and the indoor air inhaled into the indoor unit, thereby forming a heat exchange airflow. The air supply fan 140 is usually disposed downstream of the heat exchanger 130 and is driven to rotate by the motor 150 to force the indoor air to circulate through the indoor unit. That is, the air supply fan 140 sucks the indoor air from the air inlet 101 into the indoor unit, exchanges heat through the heat exchanger 130, and then discharges it into the room from the air outlet 102, thereby adjusting the indoor temperature.

[0064] The heat exchanger 130 is of a three - section type, including a first heat exchange section 131, a second heat exchange section 132, and a third heat exchange section 133. Among them, the first heat exchange section 131 is close to the front side inside the housing 100 and extends vertically from bottom to top. The second heat exchange section 132 extends obliquely upward and backward from the upper end of the first heat exchange section 131. The third heat exchange section 133 extends obliquely downward and backward from the upper end of the second heat exchange section 132. The first heat exchange section 131, the second heat exchange section 132, and the third heat exchange section 133 construct the entire heat exchanger 130 into a U - shaped structure with the opening facing downward, ensuring that all the indoor air inhaled from the air inlet 101 can be heat - exchanged.

[0065] The air supply fan 140 is a cross - flow fan and extends along the lateral direction of the housing 100. Specifically, the air supply fan 140 is located behind the first heat exchange section 131 and below the second heat exchange section 132 and the third heat exchange section 133, and is jointly surrounded by the first heat exchange section 131, the second heat exchange section 132, and the third heat exchange section 133. The motor 150 is installed at one lateral end of the air supply fan 140 and is used to controllably drive the air supply fan 140 to rotate.

[0066] This layout method can significantly save installation space, make the structure of the indoor unit more compact, and be more suitable for use in areas with limited space such as cabinets 20. At the same time, since the air supply fan 140 is surrounded by the heat exchange sections, the noise generated during the operation of the air supply fan 140 can be reduced from spreading to the external space to a certain extent, improving the user's comfort level.

[0067] Specifically, an access opening 103 is provided at a lateral end of the housing 100. The access opening 103 is used to expose the motor 150 and the air supply fan 140. The access opening 103 provides a direct passage for maintenance personnel to the motor 150. By opening the access opening 103, maintenance personnel can directly observe the operating state of the motor 150, check for abnormal sounds, overheating or other potential problems. At the same time, the access opening 103 also allows maintenance personnel to perform operations such as cleaning and fastening on the air supply fan 140 to ensure its normal operation and maintain a good air supply effect.

[0068] The design of the access opening 103 improves the maintainability of the indoor unit, eliminating the need for gas collection operations, reducing maintenance costs and time. When maintenance or servicing is required, maintenance personnel can quickly locate the problem and take corresponding measures to handle it, avoiding the inconvenience and additional costs caused by disassembling the entire housing 100.

[0069] In addition, the provision of the access opening 103 also reflects the user-friendliness and user care in product design. It can make users feel more at ease during daily use because users know that even if problems occur, they can be quickly resolved. This design detail not only enhances the overall quality of the product but also strengthens users' trust and satisfaction with the brand.

[0070] Figure 5 is a schematic side view of an air conditioner indoor unit 10 according to an embodiment of the present utility model. Figure 6 is a schematic exploded view of an access cover 160 and a gland 170 of an air conditioner indoor unit 10 according to an embodiment of the present utility model.

[0071] As Figure 5 and Figure 6 shown, an access cover 160 is provided at the access opening 103 of the rear housing 110. When maintenance or inspection is not required, the access opening 103 is closed and hidden by the access cover 160, making the appearance of the entire indoor unit more tidy and unified, while preventing foreign objects from entering. When maintenance or inspection is required, simply opening the access cover 160 allows quick access to internal components such as the motor 150 and the air supply fan 140, not only improving the maintenance efficiency but also reducing the risk of damage caused by frequent disassembly of the indoor unit.

[0072] The maintenance cover 160 covers the maintenance opening 103, and the side of the maintenance cover 160 close to the housing 100 is in contact with the outer surface of the housing 100. The maintenance cover 160 covering the maintenance opening 103 avoids the abrupt feeling caused by the exposure of the maintenance opening 103, making the appearance of the entire indoor unit more neat and smooth, meeting the aesthetic standards of modern homes. The fitting design helps to enhance the sealing performance of the maintenance opening 103, reducing the possibility of dust, moisture or other impurities entering the interior of the housing 100. This is of great significance for protecting key components such as the internal motor 150 and the air supply fan 140 from damage and maintaining the long-term stable operation of the indoor unit.

[0073] The maintenance opening 103 is a circular opening or an oval opening. Correspondingly, the maintenance cover 160 can be a circular cover or an oval cover. The edges of the circular or oval maintenance opening 103 are smooth, without sharp corners or complex edges and corners, enabling maintenance personnel to more easily access and operate internal components such as the motor 150 and the air supply fan 140 during maintenance, while reducing the risk of the edges of the maintenance opening 103 scratching the maintenance personnel.

[0074] In addition, in some cases, the space inside the housing 100 may be relatively compact. The circular or oval maintenance opening 103 can minimize the occupation of the housing 100 while ensuring sufficient opening area. This helps to improve the space utilization rate of the entire indoor unit, enabling other key components (such as the heat exchanger 130 and the air supply fan 140) to be more reasonably arranged.

[0075] The maintenance cover 160 can be made of the same or similar material and color as the rear housing 110 to ensure its coordination with the overall body.

[0076] In an alternative embodiment, at least one connecting ear 161 is provided on the periphery of the maintenance cover 160, and the housing 100 is provided with corresponding mounting holes 162. The mounting holes 162 allow fasteners to pass through to lock the maintenance cover 160 to the housing 100. The choice of fasteners can be determined according to the actual application scenario, the required fastening force and cost considerations. For example, the fasteners can be screws.

[0077] In one example, the maintenance cover 160 is circular, and the number of connecting ears 161 is two. The two connecting ears 161 are formed on the upper and lower sides of the maintenance cover 160 and are integrally formed with the maintenance cover 160. Mounting holes 162 are provided at corresponding positions of each connecting ear 161 and the housing 100.

[0078] During the installation process, first align the maintenance cover 160 with the maintenance opening 103, and align the connecting ear 161 with the mounting hole 162 on the casing 100. Then, use an appropriate tool to pass the fastener through the mounting hole 162 on the connecting ear 161 and the mounting hole 162 on the casing 100, and tighten it to the specified torque value. During the tightening process, attention should be paid to maintaining a uniform distribution of the tightening force to avoid problems caused by over-tightening or under-tightening.

[0079] A gland 170 is provided inside the casing 100. The gland 170 is used to press and fix the motor 150. The size of the maintenance opening 103 is larger than the size of the gland 170 to allow the gland 170 to be taken out from the maintenance opening 103. As an important component, the gland 170 is used to press and fix the motor 150 to ensure the stability and safety of the motor 150 during operation. Since the size of the maintenance opening 103 is larger than the gland 170, the operator can have more operating space when taking out the gland 170, reducing the operation difficulty and risk. At the same time, it also avoids damage to the casing 100 or surrounding components that may be caused when taking out the gland 170.

[0080] The present utility model also provides a cabinet 20. Figure 7 It is a schematic structural diagram of an air conditioner indoor unit 10 installed in a cabinet 20 according to an embodiment of the present utility model, as Figure 7 shown. The cabinet 20 includes a cabinet body 200 and an air conditioner indoor unit 10. The cabinet body 200 has a forward opening, and the air conditioner indoor unit 10 is installed in the cabinet body 200 through the forward opening. The specific structure of the air conditioner indoor unit 10 can refer to the above embodiment. Since the air conditioner indoor unit 10 adopts all the technical solutions of the above all embodiments, it at least has the technical effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0081] The cabinet body 200 may include a top plate 210, a bottom plate 220, a back plate (not shown in the figure), a left side plate 230, and a right side plate 240. The left side plate 230 and the right side plate 240 are respectively connected to the left and right sides of the top plate 210 and the bottom plate 220, and the left and right sides of the back plate are connected to the rear sides of the left side plate 230 and the right side plate 240. The air conditioner indoor unit 10 can be directly placed on the bottom plate 220, or can be suspended on the top plate 210 or the back plate through a bracket.

[0082] To facilitate the maintenance or repair of key components such as the motor 150 and the air supply fan 140 inside the air conditioner indoor unit 10, the left side plate 230 or the right side plate 240 of the cabinet body 200 is configured to be controllably rotated outward to open.

[0083] In the embodiment shown in the drawings of the present utility model, since the maintenance opening 103 is located at the right end of the casing 100, accordingly, the right side plate 240 of the cabinet body 200 is configured to be controllably rotated outward to open.

[0084] When maintenance or repair of the motor 150 and the air supply fan 140 is required, rotating the right side plate 240 outwards can expose the inspection cover 160. Then, by removing the inspection cover 160, direct access to the internal motor 150 and air supply fan 140 can be achieved without disassembling other components or moving the entire device. This greatly simplifies the maintenance process and saves time and labor costs.

[0085] Vertical extension shafts 201 are respectively provided at the upper and lower ends of the right side plate 240 (similarly applicable to the left side plate 230), and corresponding shaft holes 202 that match these shafts 201 are provided on the top plate 210 and the bottom plate 220. This design allows the right side plate 240 to pivotally connect through the shafts 201 and be able to flip outwards when needed to expose the inspection opening 103.

[0086] The shafts 201 can be arranged near the rear side at the upper and lower ends of the right side plate 240, such that when the right side plate 240 flips outwards and backwards, it can be closest to the rear part of the machine housing 100 to the maximum extent, thus saving indoor space. This is particularly important for installation environments with limited space and avoids the risk of collision with surrounding objects during the flipping process.

[0087] To prevent the right side plate 240 from freely rotating in the non-inspection state, a limiting structure such as a spring pin can be provided on its front side. These limiting structures can be easily unlocked when needed to release the right side plate 240 for inspection, and remain firmly locked in the non-inspection state.

[0088] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present utility model have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present utility model can still be directly determined or derived based on the content disclosed in the present utility model without departing from the spirit and scope of the present utility model. Therefore, the scope of the present utility model should be understood and determined to cover all these other variations or modifications.
