When the existing embedded air conditioner indoor unit needs to be maintained or replaced with core components such as a fan and a motor, the air conditioning system is required to be subjected to air collecting operation, namely refrigerant is recovered or discharged, so that the damage to the environment and human body caused by refrigerant leakage is avoided. Then, the whole air conditioning unit is detached from the cabinet, so that specific maintenance or replacement operation can be performed.

The utility model provides an air conditioner indoor unit 10 and a cabinet 20 which are easy to maintain, and aims to solve the problem that a motor 150 and an air supply fan 140 of the existing air conditioner indoor unit 10 are inconvenient to maintain.

An air conditioner is generally classified into a single air conditioner in which all components are installed in one body, and a split air conditioner in which all components are split between an indoor unit and an outdoor unit. In the following description, the present utility model is described with reference to an embodiment for a split type air conditioner. In addition, the air conditioning indoor unit 10 of the present utility model is provided with an outdoor unit of the same type as a general outdoor unit, and a description of the outdoor unit portion will be omitted below.

Fig. 1 is a schematic structural view of an air conditioning indoor unit 10 in which an air intake 101 is in a closed state according to an embodiment of the present utility model, fig. 2 is a schematic structural view of the air conditioning indoor unit 10 in which the air intake 101 is in an open state according to an embodiment of the present utility model, fig. 3 is a schematic exploded view of the air conditioning indoor unit 10 according to an embodiment of the present utility model, and fig. 4 is a schematic cross-sectional view of the air conditioning indoor unit 10 according to an embodiment of the present utility model.

Referring to fig. 1 to 4, an air conditioning indoor unit 10 according to the present utility model mainly includes a cabinet 100, a heat exchanger 130, an air supply fan 140, and a motor 150.

The cabinet 100 may house various components for indoor unit operation, including a heat exchanger 130, an air supply fan 140, and a motor 150, among others. The front side of the casing 100 is provided with an air inlet 101 and an air outlet 102, and the air inlet 101 is located above the air outlet 102. By the arrangement mode, the indoor unit can enter air from the front upper part and exit air from the front lower part.

When the indoor unit needs to be embedded in a limited space area such as the cabinet 20, the front upper air inlet and front lower air outlet modes show unique advantages. Since both the air inlet 101 and the air outlet 102 are positioned at the front side of the cabinet 100 and are not limited by the top plate 210 and the bottom plate 220 of the cabinet 20, there is no concern about the problem of air flow blockage or insufficient space, and the installation flexibility and adaptability of the indoor unit are greatly improved.

The shape of the casing 100 may be rectangular, and the air inlet 101 and the air outlet 102 are elongated openings extending along the transverse direction of the casing 100. On the one hand, the front space of the casing 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 strip openings are also beneficial to the uniform distribution of air, so that the problem that the air quantity in a local area is too large or too small is avoided.

The air inlet area of the air inlet 101 is larger than the air outlet area of the air outlet 102. In this way, even if the wind speed at the air inlet 101 is low, a sufficient air quantity can be ensured to enter the indoor unit, and the air is discharged from the air outlet 102 at a high wind speed after heat exchange by the heat exchanger 130. Meanwhile, the area of the air inlet 101 is large, so that the local wind speed of the air inlet 101 can be reduced, noise and vibration are reduced, and the comfort and stability of the indoor unit are improved.

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 inlet area of the air inlet 101 is greater than the air outlet area of the air outlet 102.

In an alternative embodiment, the cabinet 100 may be composed of front and rear parts, including the rear housing 110 and the front frame 120. The front side of the rear case 110 is open to facilitate the direct installation of the heat exchanger 130, the blower fan 140, the motor 150, and the like therein. The front frame 120 serves to cover the front side opening of the rear case 110, and is detachably coupled to the rear case 110 by fasteners.

In the process of installing the indoor unit to the cabinet 20, the rear housing 110 of the indoor unit may be installed first, and then the front frame 120 is installed on the rear housing 110, which reduces complexity of field installation and improves installation efficiency. When the indoor unit fails, the exposed components can be directly contacted only by removing the front frame 120, and necessary checking and maintenance work can be performed.

In an alternative embodiment, the front frame 120 includes a main frame 121 and a front panel 122, wherein the air inlet 101 is formed in an upper region of the main frame 121, the air outlet 102 is formed in a lower region of the main frame 121, and a lower end of the front panel 122 is pivotally mounted to the main frame 121 and configured to controllably flip up and down around a pivot point to open or close the air inlet 101.

It will be appreciated 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, the condition of up-down air channeling may occur, that is, the cold air and the hot air are mixed with each other inside the casing 100, which results in a decrease in heat exchange efficiency and even affects uniformity of indoor temperature.

In the above embodiment, after the front panel 122 is turned forward and opened, the front panel 122 may serve as a barrier for guiding air flow, so as to ensure that cold air or hot air entering from the air inlet 101 can flow along a predetermined path, exchange heat through the heat exchanger 130, and then be discharged from the air outlet 102. Meanwhile, the front panel 122 can also prevent the air discharged from the air outlet 102 from directly flowing back to the air inlet 101, so that the problem of upward and downward air channeling is effectively avoided.

The air inlet 101 may be provided with an air inlet grille 123, and the air inlet grille 123 is formed by a plurality of longitudinal ribs and transverse ribs in a staggered manner.

The introduction of the air grill 123 is critical to the guiding of 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 entering air flow and reduce the occurrence of vortex and turbulence phenomena. This not only improves the stability of the air flow, but also ensures that the air can be uniformly distributed to various portions of the heat exchanger 130, thereby improving heat exchange efficiency.

The air intake grill 123 is designed in consideration of the structural strength of the main frame 121. By increasing the number and density of longitudinal ribs and transverse ribs, the overall structure of the main frame 121 is reinforced. This reinforced design makes the main frame 121 more stable against external pressure and impact, reducing the risk of deformation and damage. Meanwhile, the air inlet grid 123 is also used as a part of the main frame 121, so that partial load is shared, and the structural strength and durability of the whole indoor unit are further improved.

The heat exchanger 130 is disposed in the casing 100 and is located in the airflow path between the air inlet 101 and the air outlet 102. The heat exchanger 130 exchanges heat with indoor air sucked into the indoor unit mainly by means of, for example, a refrigerant flowing inside thereof, thereby forming a heat exchange air flow. The blower fan 140 is generally disposed downstream of the heat exchanger 130, and is rotated by the motor 150 to forcibly circulate the indoor air through the indoor unit. That is, the blower fan 140 sucks the indoor air from the air inlet 101 into the indoor unit, exchanges heat with the heat exchanger 130, and then discharges the indoor air from the air outlet 102 into the room, thereby adjusting the indoor temperature.

The heat exchanger 130 is three-stage, and includes a first heat exchange section 131, a second heat exchange section 132 and a third heat exchange section 133, wherein the first heat exchange section 131 is close to the front side of the interior of the casing 100 and extends vertically from bottom to top, the second heat exchange section 132 extends obliquely upward and rearward from the upper end of the first heat exchange section 131, and the third heat exchange section 133 extends obliquely downward and rearward 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 integrally construct the heat exchanger 130 in a U-shaped structure with a downward opening, ensuring that all indoor air sucked from the air inlet 101 can be heat-exchanged.

The blower fan 140 is a cross flow fan and extends in the lateral direction of the casing 100. Specifically, the blower fan 140 is located behind the first heat exchange section 131, below the second heat exchange section 132 and the third heat exchange section 133, and is surrounded by the first heat exchange section 131, the second heat exchange section 132 and the third heat exchange section 133, and the motor 150 is mounted at one lateral end of the blower fan 140 for controllably driving the blower fan 140 to rotate.

The layout can remarkably save the installation space, so that the indoor unit is more compact in structure and is more suitable for being used in areas with limited space such as the cabinet 20. Meanwhile, since the air supply fan 140 is surrounded by the heat exchange section, noise generated when the air supply fan 140 is operated can be reduced to spread to an external space to a certain extent, and the use comfort of a user can be improved.

In particular, an access opening 103 is provided at one lateral end of the cabinet 100, the access opening 103 being adapted to expose the motor 150 and the blower fan 140. The access port 103 provides a direct access to the motor 150 for maintenance personnel, who can visually observe the operating condition of the motor 150 by opening the access port 103 to check for abnormal sounds, overheating, or other potential problems. Meanwhile, the maintenance personnel can clean and fasten the air supply fan 140 by the maintenance hole 103, so that the normal operation of the air supply fan is ensured and the good air supply effect is maintained.

The design of the access port 103 improves maintainability of the indoor unit, does not need to perform air collection operation, and reduces maintenance cost and time. When maintenance or servicing is required, a serviceman can quickly locate the problem and take corresponding measures to treat the problem, so that inconvenience and extra cost caused by disassembling the whole machine shell 100 are avoided.

In addition, the provision of access opening 103 also embodies humanization of the product design and user care. The utility model can make the user feel more secure in the daily use process, because the user can quickly solve the problem even if the user encounters the problem clearly. The design details not only improve the texture of the whole product, but also enhance the trust and satisfaction degree of the user on brands.

Fig. 5 is a schematic side view of an air conditioning indoor unit 10 according to one embodiment of the present utility model, and fig. 6 is a schematic disassembled view of an access cover 160 and a gland 170 of the air conditioning indoor unit 10 according to one embodiment of the present utility model.

As shown in fig. 5 and 6, 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 opening 103 is closed and hidden by the access cover 160, so that the appearance of the whole indoor unit is tidier and unified, and foreign matters are prevented from entering. When maintenance or inspection is required, the components such as the motor 150 and the blower fan 140 inside the indoor unit can be quickly accessed by simply opening the access cover 160, so that not only is maintenance efficiency improved, but also damage risk caused by frequently disassembling the indoor unit is reduced.

The access cover 160 covers the access opening 103, and one side thereof adjacent to the cabinet 100 is fitted to the outer surface of the cabinet 100. The access cover 160 covers the access opening 103, so that abrupt sense caused by exposure of the access opening 103 is avoided, the appearance of the whole indoor unit is tidier and smoother, and the aesthetic standard of modern home is met. The conforming design helps to enhance the sealing of the access opening 103 and reduces the likelihood of dust, moisture or other impurities entering the interior of the enclosure 100. This is important for protecting the internal motor 150, the blower fan 140, and other critical components from damage, and maintaining long-term stable operation of the indoor unit.

The access opening 103 is a circular opening or an oval opening. Accordingly, access cover 160 may be a circular cover or an oval cover. The circular or oval access opening 103 has smooth edges and no sharp corners or complex corners, so that maintenance personnel can more easily access and operate the internal motor 150, the air supply fan 140 and other components when performing maintenance, and the risk of scratching the edges of the access opening 103 is reduced.

Furthermore, in some cases, the space inside the casing 100 may be relatively compact. The circular or oval access opening 103 can minimize occupation of the cabinet 100 while securing a sufficient opening area. This helps to improve the space utilization of the entire indoor unit, enabling other critical components (e.g., heat exchanger 130, blower fan 140, etc.) to be more rationally laid out.

The access cover 160 may be of the same or similar material and color as the rear housing 110 to ensure its compatibility with the overall fuselage.

In an alternative embodiment, at least one connecting lug 161 is provided on the periphery of the access cover 160, the connecting lug 161 and the housing 100 being provided with corresponding mounting holes 162, the mounting holes 162 allowing fasteners to pass through to lock the access cover 160 to the housing 100. The choice of fastener may be determined by the actual application, the required tightening force and cost considerations, for example the fastener may be a screw.

In one example, the access cover 160 is circular, the number of the connection lugs 161 is two, and the two connection lugs 161 are formed on the upper side and the lower side of the access cover 160 and are integrally formed with the access cover 160, and each connection lug 161 and the corresponding position of the casing 100 are provided with a mounting hole 162.

During installation, access cover 160 is first aligned with access opening 103 and attachment lugs 161 are aligned with mounting holes 162 in enclosure 100. Fasteners are then passed through mounting holes 162 in the attachment lugs 161 and mounting holes 162 in the housing 100 using appropriate tools and tightened to the specified torque values. During tightening, care should be taken to maintain a uniform distribution of tightening force, avoiding problems caused by over tightening or over loosening.

A gland 170 is disposed in the casing 100, the gland 170 is used for pressing and fixing the motor 150, and the size of the access opening 103 is larger than that of the gland 170, so as to allow the gland 170 to be taken out from the access opening 103. The gland 170 is used as an important component for the press-fit fixation of the motor 150 to ensure stability and safety of the motor 150 during operation. Because the size of the access opening 103 is larger than that of the gland 170, an operator can have a larger operation space when taking out the gland 170, and the operation difficulty and risk are reduced. At the same time, damage to the housing 100 or surrounding components that may occur when the gland 170 is removed is also avoided.

The present utility model also provides a cabinet 20, and fig. 7 is a schematic block diagram of an air conditioner indoor unit 10 according to an embodiment of the present utility model embedded in the cabinet 20, and as shown in fig. 7, the cabinet 20 includes a cabinet body 200 and the air conditioner indoor unit 10, the cabinet body 200 having a forward opening, the air conditioner indoor unit 10 being embedded in the cabinet body 200 through the forward opening. The specific structure of the indoor unit 10 of the air conditioner may refer to the above embodiments, and since the indoor unit 10 of the air conditioner adopts all the technical solutions of all the embodiments, at least the technical effects brought by the technical solutions of the embodiments are not described in detail herein.

A mounting opening 201 corresponding to the access opening 103 is formed in one transverse end of the cabinet 200, and a mounting cover 202 for opening and closing the mounting opening 201 is arranged at the mounting opening 201. In this way, during maintenance, maintenance personnel do not have to remove the entire air conditioning indoor unit 10 from cabinet 20, which provides significant time and cost savings. A portion of the cabinet 100 (the area covered by the access cover 160) is exposed by simply removing the mounting cover 202. Subsequently, by further removing the access cover 160, the gland 170, motor 150, blower fan 140, etc., are exposed.

The design of the mounting port 201 and access port 103 allows a serviceman to quickly locate and access the components to be serviced without having to disassemble the entire apparatus, and simply remove the mounting cover 202 and access cover 160. The directly exposed components allow maintenance personnel to more easily perform inspection, repair or replacement work, avoiding potential damage to the equipment due to frequent disassembly and assembly of the entire equipment. At the same time, maintenance is performed inside cabinet 20 without additional work space or tools, which means less maintenance time and lower maintenance costs for the user, thereby improving product satisfaction.

Fig. 8 is a schematic exploded view of a mounting cover 202 of a cabinet 20 according to one embodiment of the present utility model, as shown in fig. 8, the mounting cover 202 may be embedded in a mounting port 201, an inner edge of the mounting port 201 is provided with a step 203, a peripheral edge of an inner surface of the mounting cover 202 abuts against the step 203, and an outer surface of the mounting cover 202 is flush with an outer surface of the cabinet body 200.

The step 203 provided on the inner edge of the mounting opening 201 provides a stable support surface for the mounting cap 202. When the peripheral edge of the inner surface of the mounting cap 202 abuts against the step 203, the mounting cap 202 can be secured in position in the mounting port 201, and is not liable to shake or fall off. This design aids in positioning during installation so that the mounting cap 202 can be accurately inserted into the mounting port 201.

In addition, the outer surface of the mounting cover 202 is flush with the outer surface of the cabinet 200, further improving the overall aesthetic appearance of the cabinet 200. This design allows the mounting cover 202 to be almost integral with the cabinet 200 in the closed position without visible seams or protrusions, thereby maintaining a clean and smooth exterior of the cabinet 200. This is certainly an important consideration for users who pursue the aesthetics and cleanliness of the home.

The mounting cover 202 may also be provided with a structure similar to the connecting lugs 161 and provided with mounting holes 162. In this way, the mounting cover 202, the access cover 160, and the cabinet 100 may be connected by the same fastener.

By tightly coupling the mounting cover 202, the access cover 160, and the cabinet 100 together with the same fastener, a more stable overall structure can be formed. This structure not only helps to reduce noise and vibration caused by loosening of parts, but also improves durability and service life of the apparatus to some extent.

During maintenance, if access cover 160 or mounting cover 202 is required to be opened to access the internal components, the disassembly and reinstallation operations may be accomplished more quickly because they are connected using the same fasteners. This not only saves maintenance time, but also reduces the risk of damage to the components due to frequent disassembly and assembly.

The cabinet 200 may include a top plate 210, a bottom plate 220, a back plate (not shown), a left side plate 230, and a right side plate 240, wherein the left side plate 230 and the right side plate 240 are respectively connected to 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 rear sides of the left side plate 230 and the right side plate 240. The indoor unit 10 may rest directly on the bottom plate 220 or may be suspended from the top plate 210 or the back plate by a bracket.

In one example, access opening 103 is located at the right end of rear housing 110, mounting opening 201 is located at right side plate 240 of cabinet 200, and the size of mounting opening 201 is slightly larger than the size of access opening 103, ensuring that access cover 160 has sufficient space within mounting opening 201 to allow for movement and adjustment to more easily achieve docking and securing with access opening 103.
