Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an embedded air conditioning indoor unit and an air conditioner. Background Technology

[0002] Traditional household wall-mounted air conditioners are divided into indoor and outdoor units. Existing indoor units usually adopt an integrated shell structure, which needs to be suspended on the wall during installation. However, the shell does not fit well with the building structure and is not coordinated with the interior decoration. Utility Model Content

[0003] This application provides an embedded air conditioner indoor unit and an air conditioner to solve existing problems.

[0004] In a first aspect, this application provides an embedded air conditioner indoor unit and an air conditioner, comprising:

[0005] The housing includes a first mounting portion, a second mounting portion, and an air outlet portion; the first mounting portion is at least for fitting against a vertical wall, and the second mounting portion is at least for fitting against a ceiling;

[0006] The air outlet is connected to the first mounting part and the second mounting part. The air outlet is arranged facing forward and has air outlets and return air inlets spaced apart.

[0007] A heat exchanger is installed inside a shell; the air inlet and return air outlet of the heat exchanger are connected, and the air outlet and air outlet of the heat exchanger are connected.

[0008] An exhaust fan is used to guide airflow from the return air inlet to the heat exchanger and discharge the heat-exchanged airflow from the heat exchanger to the casing through the exhaust air inlet.

[0009] By adopting the above technical solution and through a three-part shell structure design, a tight fit with building components is achieved. The embedded air conditioner indoor unit includes a first mounting part, a second mounting part, and an air outlet part. The first mounting part is tightly fitted to the vertical wall, the second mounting part is tightly fitted to the ceiling, and the air outlet part serves as a connecting part to form a complete airflow channel.

[0010] In practical implementation, the air outlet can adopt an inclined design, with its first end connected to the first mounting part and its second end connected to the second mounting part, forming a smoothly transitional structural form. At the same time, the air outlet and return air outlet adopt an alternating layout and optimize their relative positional relationship to ensure the rationality of airflow organization.

[0011] It is easy to understand that, compared to the single-shell structure design used in existing technologies, this application achieves a perfect fit with building components through a three-part shell structure, solving the installation gap problem existing in traditional designs, enhancing the product's aesthetics and integration, and allowing it to better blend into modern interior decoration environments. At the same time, the optimized layout of the air outlets and return air inlets significantly improves airflow organization efficiency and enhances the overall performance of the air conditioning system.

[0012] In some embodiments of this application, the air outlet is inclined downwards;

[0013] The first end of the air outlet is connected to the first mounting part, and the second end of the air outlet is connected to the second mounting part.

[0014] The air outlet forms a downward-sloping airflow guide structure, which not only ensures that the airflow naturally sinks to cover the human activity area, but also achieves a seamless transition between the shell and the building components by connecting the first end to the first mounting part and the second end to the second mounting part, while hiding the gaps in the internal structure and improving the aesthetics.

[0015] In some embodiments of this application, the air outlet is provided with a shielding strip, which can be used to block the gap between the air outlet and the vertical wall and ceiling.

[0016] The shielding strip can fill the installation gap between the air outlet and the wall or ceiling, eliminating the visual discontinuity of traditional recessed air conditioners, while preventing dust accumulation and improving the overall aesthetics.

[0017] In some embodiments of this application, the first mounting part is provided with a first bracket, and the first mounting part can be mounted on a vertical wall through the first bracket;

[0018] And / or, the second mounting part is provided with a second bracket, and the second mounting part can be mounted on the ceiling via the second bracket.

[0019] The modular installation structure of the first and second brackets allows the indoor unit of the air conditioner to be flexibly installed by wall mounting, ceiling mounting, or a combination of both, which ensures the stability of the installation and improves its adaptability to different decoration environments.

[0020] In some embodiments of this application, the first mounting part is provided with a first bracket; the air outlet part is provided with a first shielding strip, the first shielding strip extends out of the first mounting part, and the first shielding strip is used to abut against the vertical wall surface;

[0021] The second mounting section is provided with a second bracket; the air outlet section is provided with a second shielding strip, which extends out of the second mounting section and is used to abut against the ceiling.

[0022] The first and second brackets provide dual fixation to the wall and ceiling, ensuring installation stability. At the same time, the elastic abutment structure of the first and second shielding strips can conceal installation gaps, maintain aesthetics, and achieve a seamless fit.

[0023] In some embodiments of this application, the air outlet extends in a horizontal direction, and the first mounting part, the second mounting part, and the air outlet are connected in sequence in a plane perpendicular to the air outlet extending direction.

[0024] Connecting the first mounting section, the second mounting section, and the air outlet section sequentially in a plane perpendicular to the direction of air outlet extension can enhance the overall rigidity of the indoor unit. At the same time, the geometric layout naturally forms an inclined air delivery angle, improving comfort.

[0025] In some embodiments of this application, the air outlet is located below the air return outlet in the height direction of the housing.

[0026] By placing the air outlet below the return air outlet, an airflow pattern of downward supply and upward return can be formed, allowing cold air to sink naturally and hot air to rise and return. This conforms to the principle of thermodynamic convection, which can significantly improve the uniformity of temperature distribution and avoid the discomfort caused by direct cold air blowing.

[0027] In some embodiments of this application, the return air vent faces forward or is tilted upward;

[0028] The housing is equipped with a flow guide located inside the air outlet, which directs the airflow from the air outlet downwards.

[0029] By using forward-facing or angled upward-facing return air vents in conjunction with the forced downward blowing guidance of the air outlet guides, a stepped airflow circulation can be formed: the return air vents draw in hot air from the upper part of the room, while the air outlet guides precisely deliver the processed airflow downwards, which not only avoids airflow short-circuiting but also enhances the convection efficiency of hot and cold air, significantly improving the uniformity and comfort of cooling.

[0030] In some embodiments of this application, the extension direction of the air outlet is arranged parallel to the extension direction of the housing;

[0031] There are multiple return air vents, including a first return air vent and a second return air vent. The first return air vent is located on one side of the extension direction of the air outlet, and the second return air vent is located on the other side of the extension direction of the air outlet.

[0032] The parallel layout of the air outlets and the symmetrically distributed return air inlets on both sides can create a balanced bidirectional airflow circulation system: the air outlets deliver air evenly along the length of the casing, while the return air inlets on both sides simultaneously draw in indoor air, effectively eliminating dead air zones, achieving rapid temperature regulation in a large space, and reducing local temperature differences.

[0033] Secondly, this application provides an air conditioner, including an embedded air conditioner indoor unit as described in any of the first aspects. Attached Figure Description

[0045] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0046] As described in the background section, traditional household wall-mounted air conditioner indoor units typically employ a single-plane installation structure, resulting in insufficient fit between the casing and building components. Since the return air vent is usually located at the top of the casing, a noticeable gap exists between the top of the unit and the ceiling during installation, affecting not only aesthetics but also potentially causing airflow short-circuiting and reducing heat exchange efficiency.

[0047] Therefore, existing embedded air conditioner indoor units still have significant shortcomings in terms of installation fit and overall aesthetics.

[0048] To address the aforementioned issues, this application provides an embedded air conditioner indoor unit that achieves a tight fit with building components through a three-part shell structure design. The embedded air conditioner indoor unit includes a first mounting section, a second mounting section, and an air outlet section. The first mounting section is tightly fitted to a vertical wall, the second mounting section is tightly fitted to the ceiling, and the air outlet section serves as a connecting part to form a complete airflow channel.

[0049] In practical implementation, the air outlet can adopt an inclined design, with its first end connected to the first mounting part and its second end connected to the second mounting part, forming a smoothly transitional structural form. At the same time, the air outlet and return air outlet adopt an alternating layout and optimize their relative positional relationship to ensure the rationality of airflow organization.

[0050] It is easy to understand that, compared to the single-shell structure design used in existing technologies, this application achieves a perfect fit with building components through a three-part shell structure, solving the installation gap problem existing in traditional designs, enhancing the product's aesthetics and integration, and allowing it to better blend into modern interior decoration environments. At the same time, the optimized layout of the air outlets and return air inlets significantly improves airflow organization efficiency and enhances the overall performance of the air conditioning system.

[0057] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0058] An air conditioner consists of an indoor unit and an outdoor unit. The indoor unit exchanges heat with the indoor air through a built-in heat exchanger, absorbing heat to lower the room temperature during cooling and releasing heat to raise the temperature during heating. The outdoor unit handles the refrigerant's state conversion and heat transfer. During cooling, the outdoor unit uses a condenser to release the heat absorbed by the indoor unit to the outdoor environment, while the compressor drives the refrigerant circulation and increases its pressure and temperature. During heating, a four-way valve switches the flow direction, extracting heat from the outdoor air and transferring it indoors.

[0059] In cooling mode, the indoor unit's heat exchanger acts as an evaporator, absorbing heat from the indoor air. Hot indoor air is drawn in and flows through the evaporator, where the refrigerant evaporates and absorbs heat within the evaporator tubes, cooling the air before it is expelled through the air deflector. Simultaneously, the outdoor unit's heat exchanger functions as a condenser. The compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure state, which is then sent to the condenser and forced to dissipate heat through a fan, causing the refrigerant to condense into a liquid state. Subsequently, the low-temperature refrigerant, after being throttled and depressurized by the expansion valve, re-enters the indoor unit's evaporator, completing the refrigeration cycle.

[0060] In heating mode, the four-way valve switches the refrigerant flow, allowing the indoor and outdoor unit heat exchangers to switch functions. At this time, the indoor unit's heat exchanger acts as a condenser, where the high-temperature, high-pressure refrigerant discharged from the compressor releases heat, and the fan delivers the heated air into the room through the air deflector. The outdoor unit's heat exchanger then transforms into an evaporator, absorbing heat from the outdoor air. Even in low-temperature environments, heat transfer can be achieved through the compressor's work.

[0061] See Figures 1-5 This application provides an embedded air conditioner indoor unit, which may include a housing 100, a heat exchanger 200, and an air outlet fan 400.

[0062] The housing 100 can serve as the main support structure for the indoor unit of the air conditioner, forming a closed air duct space and fixing the internal components.

[0063] The housing 100 may include a first mounting portion 150, a second mounting portion 160, and an air outlet 130. The first mounting portion 150 can be used to fit against a vertical wall to ensure the unit is fixed in the vertical direction; the second mounting portion 160 can be used to fit against a ceiling to provide top support stability; and the air outlet 130 can be used for air circulation.

[0064] The air outlet 130 can connect to the first mounting part 150 and the second mounting part 160 to form a complete airflow channel. Its forward-facing structure facilitates direct airflow into the interior space. By integrating the first mounting part 150, the second mounting part 160, and the air outlet 130 into the same housing 100, installation convenience is optimized, airflow organization is ensured, and seamless integration with architectural decoration is maintained. The connections between the various parts can be rigidly fixed through a mechanical structure, ensuring the stability of the overall structure.

[0065] The air outlet 110 and the return air outlet 120 can be spaced apart at the air outlet 130. This effectively separates the supply air and return air paths, avoids airflow short-circuiting, and ensures sufficient indoor air circulation; the supply air and return air will not interfere with each other, improving heat exchange efficiency.

[0066] In the height direction of the casing 100, the air outlet 110 can be located below the return air inlet 120. This high-low arrangement can form a clear airflow circulation path: the treated low-temperature air is sent out from the lower air outlet 110, naturally settles and exchanges heat with the indoor air, and the heated airflow then flows back from the upper return air inlet 120. This arrangement makes full use of the natural convection characteristics of hot and cold air, effectively improving heat exchange efficiency.

[0067] The return air vent 120 can face forward or be tilted upward. A return air vent 120 facing forward or tilted upward can effectively capture the rising hot air flow in the room, improve the return air efficiency, and at the same time avoid energy loss caused by directly drawing in the regulated airflow that has just been delivered.

[0068] The extension direction of the air outlet 110 can be parallel to the extension direction of the housing 100. The housing 100 can be arranged parallel to the building components. The air outlet 110, extending parallel to the length of the housing 100, can form a linear and uniform air supply area, ensuring the continuity of airflow distribution. It is suitable for the temperature regulation needs of long and narrow building spaces, and the air supply airflow can cover a larger planar area.

[0069] The number of return air vents 120 can be one. The extension direction of the return air vent 120 can be parallel to the extension direction of the housing 100. By keeping the extension direction parallel to the housing 100, a continuous airflow channel can be formed, which is conducive to the smooth intake of air. The length direction of the return air vent 120 is parallel to the long side axis of the housing 100, and its cross-sectional shape is consistent with the contour of the housing 100, which can ensure that the airflow will not have a significant change in direction when it enters. This arrangement allows the return airflow to enter the air conditioner along a straight path, reducing flow resistance.

[0070] Alternatively, there can be multiple return air vents 120. These multiple return air vents 120 may include a first return air vent 121 and a second return air vent 122. The first return air vent 121 may be located on one side of the extension direction of the air outlet 110, and the second return air vent 122 may be located on the other side of the extension direction of the air outlet 110. The dual-sided arrangement of return air vents 120 can create a balanced airflow recovery system, effectively preventing air stagnation caused by unilateral return air.

[0071] The linear air supply from the air outlet 110 and the return air on both sides create a clear airflow path. Indoor air is delivered from the center of the space and naturally diffuses to both sides, finally being evenly recovered by the return air outlets 120 on both sides. This airflow organization significantly reduces dead zones and improves the uniformity of temperature regulation. At the same time, the symmetrical design of the return air on both sides balances the system's air pressure distribution, reduces fan energy consumption, and reduces noise generation from a single return air outlet 120 through the diversion effect.

[0072] The housing 100 may be equipped with a flow guide 300. The flow guide 300 may be located at the air outlet 110, directing the airflow from the air outlet 110 downwards. The flow guide 300 may consist of multiple parallel-arranged flow guide vanes, the spacing and opening of which are adjustable to adapt to different air supply requirements. By directing the airflow from the air outlet 110 downwards, the flow guide 300 can further prevent the adjusted airflow from being drawn back into the return air outlet 120.

[0073] The air guide plate can rotate 100° relative to the housing to adjust the orientation of the air guide channel. When the angle of the air guide plate changes, the air guide channel formed by adjacent air guide plates changes its extension direction, thereby achieving precise guidance of the exhaust airflow.

[0074] The rotation axis of the air guide plate can be parallel to the extension direction of the air outlet 110. When the air guide plate rotates around an axis parallel to the extension direction of the air outlet 110, the change in its plate angle will guide the airflow to deflect vertically, thereby achieving an up-and-down sweeping air supply mode. This movement mode allows the airflow to be adjusted over a wide range of angles in the vertical plane.

[0075] Alternatively, the rotation axis of the air guide plate can be perpendicular to the extension direction of the air outlet 110. When the air guide plate rotates around an axis perpendicular to the extension direction of the air outlet 110, the change in its plate angle will guide the airflow to deflect horizontally, thereby achieving a left-right sweeping air supply mode. This movement mode allows the airflow to be adjusted over a wide range of angles in the horizontal plane.

[0076] When the housing 100 of this embodiment is installed on a building component, the surface where the air outlet 130 is located forms a continuous surface with the side wall surface of the building component located on at least one side of the air outlet 130. This allows the housing 100 to be integrated into the side wall of the building component, thereby making the housing 100 essentially integrated with the building component when it is installed on the building component, thus avoiding the housing 100 from appearing abrupt and improving aesthetics.

[0077] Specifically, the building component in this embodiment can be a room or a cabinet, etc. The side wall surface of the building component can be the wall surface of the room or the surface of the cabinet. The first mounting part 150 of the housing 100 can be attached to the vertical wall surface of the building component, the second mounting part 160 of the housing 100 can be attached to the ceiling of the building component, and the air outlet 130 of the housing 100 can be exposed on the wall surface or the surface of the cabinet. The air outlet 130 is a continuous surface with the wall surface or cabinet surface located on at least one side of the air outlet 130, so that the air outlet 130 can be seamlessly integrated with the wall surface or cabinet surface, thereby improving the aesthetics.

[0078] The air outlet 130 can be tilted downwards, so that the airflow has a natural downward movement trend, which conforms to the principle of thermal aerodynamics and is conducive to achieving a more uniform indoor temperature distribution.

[0079] The first end of the air outlet 130 can be connected to the first mounting part 150, and the second end of the air outlet 130 can be connected to the second mounting part 160. This ensures continuity with the wall mounting structure and a smooth transition with the ceiling structure.

[0080] The extension direction of the air outlet 130 can be horizontal. In a plane perpendicular to the extension direction of the air outlet 130, the first mounting part 150, the second mounting part 160 and the air outlet 130 can be connected in sequence. The stable structural characteristics of the triangle formed by the sequential connection can provide rigid support and effectively disperse the vibration load during the operation of the indoor unit.

[0081] In one specific embodiment, when the first mounting part 150, the second mounting part 160, and the air outlet part 130 are connected in sequence, the cross-section of the housing 100 can be a right-angled triangle. The first mounting part 150 connects to the vertical wall, forming one right-angled side, while the second mounting part 160 forms the other right-angled side with the ceiling. The surface where the air outlet part 130 is located is an inclined plane. Thus, a continuous surface is formed between the surface where the air outlet part 130 is located and the wall, with only the air outlet part 130 exposed in the housing 100. This continuous surface is not a plane, but a folded surface.

[0082] The surface of the air outlet 130 has a certain angle with the surface of the wall, which may be related to the design of the surface of the air outlet 130. For example, when the cross-section of the housing 100 is an isosceles right triangle, the angle between the surface of the air outlet 130 and the surface of the wall is 135°.

[0083] The housing 100 may be provided with a rotatable cover 140. The cover 140 may be located above the air outlet 110. The rotation axis of the cover 140 may be parallel to the extension direction of the housing 100, and the angle between the cover 140 and the air outlet 110 may be adjusted as needed. The adjustment angle may be 0° to 90°.

[0084] The air outlet 130 may be equipped with a shielding strip, which can be used to cover the gap between the air outlet 130 and the vertical wall and ceiling, making the fit between the housing 100 and the building components more harmonious. The shielding strip may be made of elastic material, so that it can adapt to the slight deformation of different mounting surfaces and maintain a long-lasting fit.

[0085] The first mounting part 150 may be provided with a first bracket 151, and the first mounting part 150 can be mounted on a vertical wall through the first bracket 151. The first bracket 151 can be firmly connected to the vertical wall through fasteners such as expansion bolts, and bear the main load of the whole machine.

[0086] Alternatively, the second mounting part 160 may be provided with a second bracket 161, which allows the second mounting part 160 to be mounted to the ceiling. The second bracket 161 can be securely connected to the ceiling using fasteners such as expansion bolts, and bears the main load of the entire machine.

[0087] Alternatively, the first mounting portion 150 may be provided with a first bracket 151, and the second mounting portion 160 may be provided with a second bracket 161. The first bracket 151 and the second bracket 161 work together to form a bidirectional force-bearing system. The first bracket 151 bears the vertically downward load, and the second bracket 161 provides horizontal constraint. When the first bracket 151 and the second bracket 161 are used for dual-point fixation, the bracket system forms a stable spatial force-bearing frame, and the installation stability is significantly improved through the distributed support structure.

[0088] The first bracket 151 can be disposed on the first mounting part 150 to securely fix the housing 100 to the vertical wall. Meanwhile, the air outlet 130 can be provided with a first shielding strip, which extends out of the first mounting part 150 and elastically abuts against the wall. The first shielding strip can be made of a flexible material, thus concealing the installation marks of the second bracket 161 and preventing dust from entering through the top gaps.

[0089] The second bracket 161 can be disposed on the second mounting portion 160 to securely fix the housing 100 to the ceiling. Simultaneously, the air outlet 130 can be provided with a second shielding strip, which extends out of the second mounting portion 160 and elastically abuts against the ceiling. The first shielding strip can be made of a flexible material, which, through slight deformation, tightly conforms to the ceiling surface, thus concealing the installation marks of the second bracket 161 and preventing dust from entering through the top gaps. The symmetrical arrangement of the two shielding strips forms a continuous sealed boundary.

[0090] The heat exchanger 200 can be used as the core heat exchange component of the indoor unit of an air conditioner, and its function is to realize the heat transfer between the refrigerant and the air.

[0091] The heat exchanger 200 can be installed inside the housing 100. The air inlet of the heat exchanger 200 can be connected to the return air inlet 120 to ensure that the drawn-in indoor air can flow fully across the surface of the heat exchanger 200. The air outlet of the heat exchanger 200 can be connected to the air outlet 110 to allow the air that has undergone heat exchange to be discharged smoothly.

[0092] After the return air enters through the return air inlet 120, it flows through the heat exchanger 200 through the air inlet end, and after completing the heat exchange process, it is discharged through the air outlet 110 through the air outlet end.

[0093] The exhaust fan 400 can be used to drive airflow circulation. Through mechanical operation, negative pressure is generated, drawing indoor air in through the return air vent 120 and propelling the airflow through the heat exchanger 200 to complete the heat exchange process. After temperature regulation, the airflow forms positive pressure under the action of the exhaust fan 400, and is finally discharged back into the indoor space through the exhaust vent 110, forming a complete air circulation path.

[0094] The outlet fan 400 can be located in the airflow channel between the return air inlet 120 and the heat exchanger 200, with its inlet side connected to the return air inlet 120 and its outlet side connected to the air inlet of the heat exchanger 200. This series arrangement ensures that the airflow can pass through each functional module in sequence, achieving efficient heat transfer and distribution.

[0095] In summary, when the embedded air conditioner's indoor unit is in cooling mode, hot indoor air is drawn in through the first return air inlet 121 and the second return air inlet 122 on both sides of the casing 100. The outlet fan 400 generates negative pressure, pushing the return airflow to the heat exchanger 200, where a low-temperature refrigerant flows. Upon contact with the refrigerant pipe wall, the air absorbs heat, causing a rapid drop in air temperature. Simultaneously, moisture in the air condenses on the surface of the heat exchanger 200. The cooled, dry air enters the outlet 110 through the outlet end of the heat exchanger 200 and is forced downwards at a certain angle by the guide element 300. The cold air, due to its higher density, naturally sinks, forming a convection circulation with the hot indoor air. The dual return air inlets 120 continuously draw in rising hot air, completing the continuous cooling process.

[0096] When the embedded air conditioner's indoor unit is in heating mode, low-temperature indoor air is drawn in through the first return air inlet 121 and the second return air inlet 122 on both sides of the casing 100. The outlet fan 400 generates negative pressure, pushing the return airflow to the heat exchanger 200, where high-temperature refrigerant flows. The refrigerant releases heat to the air, raising its temperature. The heated air is then directed downwards through the guide vane 300 of the outlet 110, completing the heating process.

[0097] Based on the same concept, embodiments of this application also provide an air conditioner, including any of the above-mentioned embedded air conditioner indoor units.

[0098] Air conditioners can include recessed indoor and outdoor units. Recessed indoor units can be concealed to blend into the interior design, with their internal heat exchanger and air outlet working together to achieve even airflow distribution and precise control. The outdoor unit is the power core of the system, housing key components such as the compressor, heat exchanger, and fan, responsible for refrigerant compression and heat exchange.
