Description

Technical Field

[0001] The utility model relates to the field of air conditioners, in particular to an air conditioner indoor unit and a cabinet which are easy to maintain. Background Art

[0002] In modern homes, built-in air conditioners are widely used in limited spaces such as kitchens and living rooms due to their space-saving and aesthetically pleasing features. In particular, their integrated design with cabinets enhances the overall harmony and aesthetics of the home. However, this design also presents certain maintenance challenges. Traditional built-in air conditioners often require air collection—recovering or discharging refrigerant—before repairing or replacing core components such as the fan and motor. This is done to prevent refrigerant leakage and potential harm to the environment and health. Subsequently, the entire air conditioner unit must be removed from the cabinet before repair or replacement can be performed.

[0003] This process is not only tedious and time-consuming, increasing maintenance costs, but can also damage cabinets and surrounding decorations, affecting the aesthetics of the home. This is especially challenging for ordinary users without professional repair skills. Furthermore, refrigerant emissions can have adverse environmental impacts, which is inconsistent with current green and environmentally friendly home living concepts. Utility Model Content

For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0043] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0044] When existing built-in air conditioner indoor units require repair or replacement of core components such as fans and motors, the air conditioning system must first be vented to recover or discharge the refrigerant to prevent refrigerant leakage that could harm the environment and people. Subsequently, the entire air conditioner unit must be removed from the cabinet before repair or replacement can be performed.

[0045] The utility model provides an air-conditioning indoor unit 10 and a cabinet 20 that are easy to maintain, aiming to solve the problem of inconvenient maintenance of the motor 150 and the air supply fan 140 of the existing air-conditioning indoor unit 10.

[0046] Air conditioners are generally divided into two types: single-unit air conditioners, where all components are housed within a single unit, and split-unit air conditioners, where all components are housed in separate indoor and outdoor units. The following description of the present invention relates to an embodiment of a split-unit air conditioner. Furthermore, the indoor unit 10 of the present invention is paired with an outdoor unit of the same type as a conventional outdoor unit, and therefore the description of the outdoor unit will be omitted.

[0047] Figure 1 1 is a schematic structural diagram of an air conditioner indoor unit 10 with the air inlet 101 in a closed state according to an embodiment of the present invention. Figure 21 is a schematic 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 1 is a schematic exploded view of an air-conditioning indoor unit 10 according to an embodiment of the present invention. Figure 4 1 is a schematic cross-sectional view of an air-conditioning indoor unit 10 according to an embodiment of the present invention.

[0048] Reference Figures 1 to 4 The air conditioner indoor unit 10 of the present invention mainly includes a casing 100 , a heat exchanger 130 , an air supply fan 140 and a motor 150 .

[0049] The housing 100 houses various components required for the operation of the indoor unit, including a heat exchanger 130, a blower fan 140, and a motor 150. An air inlet 101 and an air outlet 102 are located on the front of the housing 100, with the air inlet 101 positioned above the air outlet 102. This layout allows the indoor unit to draw air from the upper front and exhaust air from the lower front.

[0050] When the indoor unit needs to be installed in a space-constrained area such as a cabinet 20, the front-up air intake and front-down air outlet configuration offers unique advantages. Because the air inlet 101 and air outlet 102 are both located on the front side of the housing 100 and are not restricted by the top panel 210 and bottom panel 220 of the cabinet 20, there is no need to worry about airflow obstruction or insufficient space, greatly improving the installation flexibility and adaptability of the indoor unit.

[0051] The housing 100 can be rectangular in shape, with the air inlet 101 and air outlet 102 each being a long strip extending transversely of the housing 100. This allows full utilization of the front space of the housing 100, allowing the air inlet 101 and air outlet 102 to occupy a larger area, thereby improving air flow efficiency. Furthermore, the long strip facilitates even air distribution, avoiding the problem of excessive or insufficient airflow in certain areas.

[0052] The air inlet area of the air inlet 101 is larger than the air outlet area of the air outlet 102. This ensures that even if the wind speed at the air inlet 101 is low, sufficient air volume can enter the indoor unit. After heat exchange at the heat exchanger 130, it is discharged from the air outlet 102 at a higher wind speed. Furthermore, the larger area of the air inlet 101 can also reduce the local wind speed at the air inlet 101, reducing noise and vibration, and improving the comfort and stability of the indoor unit.

[0053] For example, the left and right length of the air inlet 101 is equal to the left and right length of the air outlet 102, and the upper and lower heights of the air inlet 101 are greater than the upper and lower heights of the air outlet 102, which can ensure that the air inlet area of the air inlet 101 is greater than the air outlet area of the air outlet 102.

[0054] In an alternative embodiment, the housing 100 may be composed of two parts, a rear housing 110 and a front frame 120. The front side of the rear housing 110 is open, facilitating direct installation of components such as the heat exchanger 130, the blower fan 140, and the motor 150. The front frame 120 covers the front opening of the rear housing 110 and is detachably connected to the rear housing 110 via fasteners.

[0055] When 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 installation efficiency. If the indoor unit malfunctions, simply remove the front frame 120 to directly access the exposed components and perform necessary inspection and repair work.

[0056] In an optional embodiment, the front frame 120 includes a main frame 121 and a front panel 122, wherein the air inlet 101 is opened in the upper area of the main frame 121, and the air outlet 102 is opened in the lower area of the main frame 121, and the lower end of the front panel 122 can be pivotally mounted on the main frame 121 and configured to be controlled to flip up and down around the pivot point to open or close the air inlet 101.

[0057] It can be understood that during the use of the indoor unit, if the airflow between the air inlet 101 and the air outlet 102 is not properly isolated and guided, upward and downward air movement may occur, that is, cold air and hot air mix with each other inside the casing 100, resulting in reduced heat exchange efficiency and even affecting the uniformity of the indoor temperature.

[0058] In the above embodiment, when the front panel 122 is flipped forward and opened, it can serve as a barrier to guide airflow, ensuring that the cold air or hot air entering from the air inlet 101 can flow along a predetermined path, pass through the heat exchanger 130, and then be discharged from the air outlet 102. At the same time, the front panel 122 can also prevent the air discharged from the air outlet 102 from directly flowing back to the air inlet 101, effectively avoiding the problem of upward and downward airflow.

[0059] The air inlet 101 may be provided with an air inlet grille 123 , which is composed of a plurality of longitudinal ribs and transverse ribs interlaced with each other.

[0060] The introduction of the air inlet grille 123 is crucial for guiding airflow. The staggered arrangement of longitudinal and transverse ribs forms an orderly grid structure that effectively disperses and guides incoming airflow, reducing eddies and turbulence. This not only improves airflow stability but also ensures even distribution of air throughout the heat exchanger 130, thereby enhancing heat exchange efficiency.

[0061] The design of the air inlet grille 123 also takes into account the structural strength of the main frame 121. By increasing the number and density of longitudinal and transverse ribs, the overall structure of the main frame 121 is strengthened. This enhanced design makes the main frame 121 more stable when subjected to external pressure and impact, reducing the risk of deformation and damage. Furthermore, as part of the main frame 121, the air inlet grille 123 itself shares some of the load, further enhancing the structural strength and durability of the entire indoor unit.

[0062] The heat exchanger 130 is disposed within the housing 100 and is located in the airflow path between the air inlet 101 and the air outlet 102. The heat exchanger 130 primarily exchanges heat with indoor air drawn into the indoor unit via a refrigerant flowing within it, thereby forming a heat exchange airflow. The air supply fan 140 is typically disposed downstream of the heat exchanger 130 and is driven by a motor 150 to forcefully circulate indoor air through the indoor unit. Specifically, the air supply fan 140 draws indoor air into the indoor unit from the air inlet 101, exchanges heat through the heat exchanger 130, and then discharges the air into the room through the air outlet 102, thereby regulating the indoor temperature.

[0063] The heat exchanger 130 is a three-stage structure, comprising a first heat exchange section 131, a second heat exchange section 132, and a third heat exchange section 133. The first heat exchange section 131 is located near the interior front side of the housing 100 and extends vertically from bottom to top. The second heat exchange section 132 extends upward and rearward from the upper end of the first heat exchange section 131. The third heat exchange section 133 extends downward and rearward from the upper end of the second heat exchange section 132. The first, second, and third heat exchange sections 131, 132, 133 form a U-shaped structure with the opening facing downward, ensuring that all indoor air drawn in through the air inlet 101 receives heat exchange treatment.

[0064] The air supply fan 140 is a cross-flow fan and extends in 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. The air supply fan 140 is 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 mounted at one lateral end of the air supply fan 140 to drive the air supply fan 140 in a controlled manner.

[0065] This layout significantly saves installation space, making the indoor unit more compact and more suitable for use in areas with limited space, such as cabinets 20. Furthermore, since the air supply fan 140 is surrounded by the heat exchange section, the noise generated by the air supply fan 140 during operation can be reduced to a certain extent to improve user comfort.

[0066] Specifically, an access hatch 103 is provided at one lateral end of the housing 100, exposing the motor 150 and the air supply fan 140. This hatch 103 provides direct access to the motor 150 for maintenance personnel. By opening the hatch 103, maintenance personnel can visually observe the operating status of the motor 150 and check for abnormal sounds, overheating, or other potential problems. Furthermore, the hatch 103 allows maintenance personnel to clean and tighten the air supply fan 140, ensuring proper operation and maintaining optimal airflow.

[0067] The design of the inspection port 103 improves the maintainability of the indoor unit, eliminating the need for air collection operations and reducing maintenance costs and time. When repairs or maintenance are required, maintenance personnel can quickly locate the problem and take appropriate measures to address it, avoiding the inconvenience and additional costs associated with disassembling the entire housing 100.

[0068] Furthermore, the provision of access hatch 103 demonstrates the user-friendly nature of the product design. It provides users with greater peace of mind during daily use, knowing that any problems they encounter will be quickly resolved. This design detail not only enhances the overall quality of the product but also strengthens user trust and satisfaction with the brand.

[0069] Figure 5 is a schematic side view of an air-conditioning indoor unit 10 according to an embodiment of the present invention. Figure 6 1 is a schematic disassembled view of an inspection cover 160 and a pressure cover 170 of an air-conditioning indoor unit 10 according to an embodiment of the present invention.

[0070] like Figure 5 and Figure 6 As shown, the rear housing 110 is provided with an access cover 160 at the access opening 103. When maintenance or inspection is not required, the access cover 160 seals and conceals the access opening 103, giving the entire indoor unit a neater and more uniform appearance while preventing foreign matter from entering. When maintenance or inspection is necessary, simply opening the access cover 160 allows quick access to internal components such as the motor 150 and air supply fan 140. This not only improves maintenance efficiency but also reduces the risk of damage caused by frequent disassembly of the indoor unit.

[0071] The access cover 160 covers the access opening 103, and its side closest to the housing 100 is in contact with the outer surface of the housing 100. Covering the access opening 103, the access cover 160 avoids the awkward appearance of the exposed access opening 103, giving the entire indoor unit a cleaner and more streamlined appearance that meets the aesthetic standards of modern homes. This form-fitting design helps to enhance the sealing of the access opening 103 and reduce the possibility of dust, moisture, and other impurities entering the interior of the housing 100. This is crucial for protecting key components such as the internal motor 150 and air supply fan 140 from damage and maintaining the long-term stable operation of the indoor unit.

[0072] The inspection opening 103 is circular or oval. Accordingly, the inspection cover 160 can be circular or oval. The circular or oval inspection opening 103 has smooth edges, without sharp or complex corners, making it easier for maintenance personnel to access and operate internal components such as the motor 150 and air supply fan 140 while reducing the risk of scratches from the edges of the inspection opening 103.

[0073] Furthermore, in some cases, the space inside the housing 100 may be relatively compact. The circular or elliptical inspection opening 103 can minimize the space occupied by the housing 100 while ensuring sufficient opening area. This helps improve the space utilization of the entire indoor unit and allows for a more reasonable layout of other key components (such as the heat exchanger 130 and the air supply fan 140).

[0074] The access cover 160 may be made of the same or similar material and color as the rear housing 110 to ensure coordination with the entire body.

[0075] In an optional embodiment, at least one connecting ear 161 is provided on the periphery of the access cover 160. The connecting ear 161 and the housing 100 are provided with corresponding mounting holes 162. The mounting holes 162 allow fasteners to pass through to secure the access cover 160 to the housing 100. The choice of fasteners can be determined based on the actual application scenario, the required fastening force, and cost considerations. For example, the fasteners can be screws.

[0076] In one example, the inspection cover 160 is circular, and there are two connecting ears 161. The two connecting ears 161 are formed on the upper and lower sides of the inspection cover 160 and are integrally formed with the inspection cover 160. Each connecting ear 161 and the corresponding position of the casing 100 are provided with a mounting hole 162.

[0077] During installation, first align access cover 160 with access opening 103 and align connecting lugs 161 with mounting holes 162 on housing 100. Then, use an appropriate tool to insert the fasteners through mounting holes 162 on connecting lugs 161 and mounting holes 162 on housing 100 and tighten to the specified torque. During the tightening process, ensure that the tightening force is evenly distributed to avoid problems caused by overtightening or under-tightening.

[0078] A gland 170 is provided within the housing 100. The gland 170 is used to hold the motor 150 in place. The inspection port 103 is larger than the gland 170 to allow the gland 170 to be removed from the inspection port 103. The gland 170 is an important component used to hold the motor 150 in place to ensure its stability and safety during operation. Since the inspection port 103 is larger than the gland 170, the operator has more room to maneuver when removing the gland 170, reducing operational difficulty and risk. This also avoids damage to the housing 100 or surrounding components that may be caused by removing the gland 170.

[0079] The utility model also provides a cabinet 20, Figure 7 This is a schematic structural diagram of an air conditioner indoor unit 10 installed in a cabinet 20 according to an embodiment of the present invention. Figure 7 As 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 mounted in the cabinet body 200 through the forward opening. The specific structure of the air conditioner indoor unit 10 can refer to the above embodiments. Since the air conditioner indoor unit 10 adopts all the technical solutions of all the above embodiments, it at least has the technical effects brought by the technical solutions of the above embodiments, and will not be described in detail here.

[0080] A mounting opening 201 corresponding to the inspection opening 103 is provided at one lateral end of the cabinet 200. A mounting cover 202 is provided at the mounting opening 201 for opening and closing the mounting opening 201. This eliminates the need for maintenance personnel to remove the entire air conditioner indoor unit 10 from the cabinet 20, significantly saving time and cost. Simply removing the mounting cover 202 exposes a portion of the housing 100 (the area covered by the inspection cover 160). Subsequently, by further removing the inspection cover 160, components such as the gland 170, the motor 150, and the air supply fan 140 are exposed.

[0081] The design of mounting opening 201 and inspection opening 103 allows maintenance personnel to quickly locate and access components requiring repair by simply removing mounting cover 202 and inspection cover 160, without having to disassemble the entire appliance. Directly exposed components make it easier for maintenance personnel to inspect, repair, or replace the appliance, avoiding potential damage caused by frequent disassembly and installation of the entire appliance. Furthermore, maintenance can be performed within cabinet 20 without the need for additional workspace or tools. For users, this design means less maintenance time and lower costs, thereby improving product satisfaction.

[0082] Figure 8 is a schematic disassembled diagram of the installation cover 202 of the cabinet 20 according to one embodiment of the present invention, as shown in FIG. Figure 8 As shown, the installation cover 202 can be embedded in the installation opening 201, and the inner edge of the installation opening 201 is provided with a step 203. The inner periphery of the installation cover 202 abuts against the step 203, and the outer surface of the installation cover 202 is flush with the outer surface of the cabinet 200.

[0083] The step 203 provided on the inner edge of the mounting opening 201 provides a stable support surface for the mounting cover 202. When the inner edge of the mounting cover 202 abuts the step 203, the mounting cover 202 is securely positioned within the mounting opening 201, preventing it from shaking or falling out. This design facilitates positioning during installation, ensuring that the mounting cover 202 fits accurately within the mounting opening 201.

[0084] Furthermore, the outer surface of the mounting cover 202 is flush with the outer surface of the cabinet 200, further enhancing the overall aesthetics of the cabinet 200. This design allows the mounting cover 202 to virtually merge with the cabinet 200 when closed, with no visible seams or protrusions, thus maintaining a clean and smooth appearance for the cabinet 200. This is undoubtedly an important consideration for users who value aesthetics and tidiness in their homes.

[0085] The mounting cover 202 may also be provided with a structure similar to the connecting ear 161 and may offer a mounting hole 162. In this way, the mounting cover 202, the inspection cover 160 and the casing 100 may be connected by the same fastener.

[0086] By fastening the mounting cover 202, the access cover 160, and the housing 100 together using the same fasteners, a more stable overall structure is formed, which not only helps to reduce noise and vibration caused by loose components, but also improves the durability and service life of the equipment to a certain extent.

[0087] During maintenance, if it is necessary to open the access cover 160 or the mounting cover 202 to access internal components, since they are connected using the same fasteners, disassembly and reassembly can be completed more quickly. This not only saves maintenance time, but also reduces the risk of damage to components caused by frequent disassembly and installation.

[0088] The cabinet 200 may include a top panel 210, a bottom panel 220, a back panel (not shown), a left side panel 230, and a right side panel 240. The left side panel 230 and the right side panel 240 are connected to the left and right sides of the top panel 210 and the bottom panel 220, respectively. The left and right sides of the back panel are connected to the rear sides of the left and right sides of the left and right panels 230 and 240. The air conditioner indoor unit 10 may be placed directly on the bottom panel 220 or may be suspended from the top panel 210 or the back panel via a bracket.

[0089] In one example, the inspection port 103 is located at the right end of the rear shell 110, and the installation port 201 is located on the right side panel 240 of the cabinet 200. The size of the installation port 201 is slightly larger than the size of the inspection port 103, ensuring that the inspection cover 160 has enough space to move and adjust in the installation port 201, thereby making it easier to dock and fix with the inspection port 103.

[0090] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
