Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, specifically to an indoor unit for an air conditioning ceiling. Background Technology

[0002] Central air conditioning systems with surround-discharge ceiling-style indoor units are increasingly favored by consumers due to their embedded installation structure, which effectively saves indoor space. In practical applications, current ceiling-style indoor unit air conditioners, in order to save on airflow paths, use a central return air system followed by airflow in all eight directions from the return air surface. This allows for rapid air circulation, but this airflow method has shortcomings:

[0003] Since the airflow on the return air side is an intake airflow and the airflow on the outlet air side is an outlet airflow, the two airflow directions on the return air side and the outlet air side are exactly opposite. This causes the airflow on the return air side and the outlet air side to collide, which can easily lead to short circuits in the airflow field and affect the overall performance of the unit. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an air conditioning ceiling indoor unit that can effectively improve the efficiency of air intake and exhaust of the whole unit and increase the service life of the whole unit.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An indoor unit for an air conditioner ceiling is provided, comprising a housing, wherein a fan is disposed within the housing.

[0007] The housing is used to house the corresponding components, and the indoor unit is installed by suspending the housing indoors.

[0008] The housing has an air outlet and an air return surface.

[0009] The air outlet is used to output the gas discharged by the fan, forming an airflow, while the air return surface is used to draw in air for the fan to discharge.

[0010] The air outlet surface and the air return surface are located on different planes. The fan draws in gas through the air return surface and sends out airflow through the air outlet surface.

[0011] By setting the return air surface and the outlet air surface on different planes, the problem of mutual interference between return air and outlet air is effectively avoided, the efficiency of return air and outlet air is improved, the problem of short circuit in the air field between return air and outlet air is avoided, and the smoother airflow also helps to improve the service life of the whole unit.

[0012] In some embodiments, the housing includes a bottom plate and a side plate, the side plate being disposed around the outer periphery of the bottom plate, the return air surface being disposed on the side plate, and the air outlet surface being disposed on the bottom plate.

[0013] The base plate serves as a support and is located at the bottom. The air outlet is placed on the base plate, so that the exhaust airflow is discharged towards the bottom side. The side plate is located on the side, so that the air outlet and return air surfaces can be effectively avoided.

[0014] In some embodiments, the side plate is perpendicular to the surface of the base plate.

[0015] Setting the base plate downwards and making the side plates perpendicular to the base plate makes it easier for the base plate and side plates to avoid conflict and facilitates airflow.

[0016] In some embodiments, the return air surface includes a plurality of air inlets evenly distributed on the side plate surface.

[0017] Since the goal is simply to draw air into the fan, it is sufficient to maximize the number of air inlets on the side panel. Furthermore, since the air inlets are located on the side panel, which has a larger area, the number of air inlets can be effectively increased, thus improving air intake efficiency.

[0018] In some embodiments, the air outlet surface is provided with an air guiding and air outlet structure.

[0019] By constructing the air outlet surface as an air outlet grille with a guiding function, it is easier to improve the feeling of airflow.

[0020] In some embodiments, the air guiding and outlet structure includes an air guide plate with a plurality of air outlets starting from the air guide plate, the air outlets extending obliquely at a set angle.

[0021] This allows the air outlet to be tilted at a certain angle, ensuring that the air is discharged in a set direction, which improves air utilization and comfort.

[0022] In some embodiments, the air guiding and outlet structure further includes a rotating shaft, the core of which is located on the rotating shaft, and the air guiding plate rotates around the rotating shaft.

[0023] The air guide plate is driven to rotate by this shaft, thereby adjusting the direction of airflow.

[0024] In some embodiments, a heat exchanger is also included, which is located between the return air surface and the fan, and the gas drawn in by the return air surface enters the fan through the heat exchanger.

[0025] This heat exchanger is used to exchange heat with the incoming air, improving the comfort of indoor airflow.

[0026] In some embodiments, a filter screen is also included, which is located between the return air surface and the heat exchanger, and the gas drawn in by the return air surface flows through the filter screen and then through the heat exchanger.

[0027] This filter is used to remove impurities from the air entering the fan, improving the cleanliness of the indoor airflow.

[0028] Furthermore, a slot is provided on the base plate, and the filter screen is inserted into the slot to achieve fixed positioning.

[0029] In some embodiments, the heat exchanger includes a heat exchange plate surface, the bottom end of the heat exchange plate is close to the base plate, the bottom end is provided with a water receiving tray, and the heat exchange plate is placed in the water receiving tray.

[0030] Because the heat exchange plates function as heat exchangers, condensation is generated when air entering from the return air side exchanges heat with the heat exchanger. This condensate tray is used to collect the condensate and prevent leakage. Specifically, the condensate tray simply cradles the bottom of the heat exchange plates, and the condensate is drained through a conduit. In practice, the configuration of this condensate tray can be adjusted according to the internal wiring or layout of the air conditioner.

[0031] The beneficial effects of this utility model of an air conditioning ceiling indoor unit are as follows:

[0032] (1) The air conditioning ceiling indoor unit of this utility model sets the return air surface and the air outlet surface on different planes, which effectively avoids the problem of mutual conflict between return air and air outlet, improves the efficiency of return air and air outlet, avoids the problem of short circuit of air field between return air and air outlet, and also helps to improve the service life of the whole unit due to the smoother airflow.

[0033] (2) The air conditioning ceiling unit of this utility model can effectively increase the area of ​​the return air surface and the air outlet surface because the return air surface and the air outlet surface are located on different surfaces, thereby further improving the efficiency of return air and air outlet.

[0034] (3) The air conditioning ceiling unit of this utility model can increase the distance between the air inlet and outlet because the return air surface and the air outlet surface are located on different surfaces, thereby avoiding mutual interference between the air outlet and the air inlet and improving the heat exchange efficiency.

[0044] Example 1

[0045] Current ceiling-mounted air conditioners, in order to save on airflow path, use a central return air system and then distribute air in eight directions through the return air surface 4. This allows for rapid air circulation. However, this airflow method has shortcomings: since the airflow on the return air surface 4 is intake air, while the airflow on the outlet air surface 3 is outlet air, the two airflow directions on the return air surface 4 and the outlet air surface 3 are exactly opposite. This causes the airflow on the return air surface 4 and the outlet air surface 3 to collide, easily leading to airflow short-circuiting and affecting the overall performance of the unit. To address this, this embodiment discloses an air conditioner ceiling-mounted indoor unit; please refer to [link / reference]. Figures 1-4 It includes a housing 1, and a fan 2 is installed inside the housing 1.

[0046] The housing 1 is used to house the corresponding components, and the indoor unit is installed by suspending the housing 1 indoors.

[0047] The housing 1 has an air outlet surface 3 and an air return surface 4.

[0048] The air outlet surface 3 is used to output the gas discharged by the fan 2, forming an airflow, while the air return surface 4 is used to draw in air for the fan 2 to discharge.

[0049] The air outlet surface 3 and the air return surface 4 are located on different planes. The fan 2 draws in gas through the air return surface 4 and sends out airflow through the air outlet surface 3.

[0050] By setting the return air surface 4 and the air outlet surface 3 on different planes, the problem of mutual conflict between return air and air outlet is effectively avoided, the efficiency of return air and air outlet is improved, the problem of short circuit in the air field between return air and air outlet is avoided, and the airflow is smoother. The air conditioner ceiling indoor unit includes a housing 1, and a fan 2 is installed inside the housing 1.

[0051] Specifically,

[0052] The housing 1 is used to house all the components of the indoor unit of the air conditioner, and the indoor unit is installed by suspending the housing 1 indoors.

[0053] The casing 1 has an air outlet surface 3 and a return air surface 4. The air outlet surface 3 is used to output the gas discharged by the fan 2, forming an airflow; the return air surface 4 is used to draw in air for the fan 2 to discharge. The air outlet surface 3 and the return air surface 4 are located on different planes. The fan 2 draws in gas through the return air surface 4 and sends out the airflow through the air outlet surface 3, effectively avoiding the problem of mutual interference between return and outlet air, improving the efficiency of return and outlet air, avoiding the problem of airflow short circuit, and the smoother airflow also helps to improve the service life of the entire unit.

[0054] Fan 2 can be either a cross-flow fan 2 or a centrifugal fan 2. The cross-flow fan 2 is designed as a suction type, while the centrifugal fan 2 can be designed as either a blowing type or a suction type. Therefore, the indoor unit of the air conditioning ceiling can achieve efficient and energy-saving operation, while maintaining the comfort of the indoor environment, and is easy to install and maintain. It also helps to extend the service life of the entire unit.

[0055] Example 2

[0056] This embodiment discloses an indoor unit for an air conditioning ceiling. Please refer to [link / reference]. Figures 1-4 It includes a housing 1, and a fan 2 is installed inside the housing 1.

[0057] The housing 1 is used to house the corresponding components, and the indoor unit is installed by suspending the housing 1 indoors.

[0058] The housing 1 has an air outlet surface 3 and an air return surface 4.

[0059] The air outlet surface 3 is used to output the gas discharged by the fan 2, forming an airflow, while the air return surface 4 is used to draw in air for the fan 2 to discharge.

[0060] The air outlet surface 3 and the air return surface 4 are located on different planes. The fan 2 draws in gas through the air return surface 4 and sends out airflow through the air outlet surface 3.

[0061] By setting the return air surface 4 and the air outlet surface 3 on different planes, the problem of mutual conflict between return air and air outlet is effectively avoided, the efficiency of return air and air outlet is improved, the problem of short circuit in the air field between return air and air outlet is avoided, and the airflow is smoother. The air conditioner ceiling indoor unit includes a housing 1, and a fan 2 is installed inside the housing 1.

[0062] Specifically,

[0063] The housing 1 is used to house all the components of the indoor unit of the air conditioner, and the indoor unit is installed by suspending the housing 1 indoors.

[0064] The casing 1 has an air outlet surface 3 and a return air surface 4. The air outlet surface 3 is used to output the gas discharged by the fan 2, forming an airflow; the return air surface 4 is used to draw in air for the fan 2 to discharge. The air outlet surface 3 and the return air surface 4 are located on different planes. The fan 2 draws in gas through the return air surface 4 and sends out the airflow through the air outlet surface 3, effectively avoiding the problem of mutual interference between return and outlet air, improving the efficiency of return and outlet air, avoiding the problem of airflow short circuit, and the smoother airflow also helps to improve the service life of the entire unit.

[0065] Fan 2 can be either a cross-flow fan 2 or a centrifugal fan 2. The cross-flow fan 2 is designed as a suction type, while the centrifugal fan 2 can be designed as either a blowing type or a suction type. Therefore, the indoor unit of the air conditioning ceiling can achieve efficient and energy-saving operation, while maintaining the comfort of the indoor environment, and is easy to install and maintain. It also helps to extend the service life of the entire unit.

[0066] Please see Figures 1-2 To further illustrate the positional relationship between the air outlet surface 3 and the air inlet surface, based on Embodiment 1, this embodiment discloses that the housing 1 includes a bottom plate 5 and a side plate 6. The side plate 6 is arranged around the outer periphery of the bottom plate 5, the return air surface 4 is arranged on the side plate 6, and the air outlet surface 3 is arranged on the bottom plate 5.

[0067] The base plate 5 serves as a support and is located at the bottom. The air outlet 3 is placed on the base plate 5, so that the exhaust airflow is discharged towards the bottom side. The side plate 6 is located on the side, so that the air outlet 3 and the return air surface 4 can be effectively avoided.

[0068] Specifically,

[0069] The housing 1 consists of a base plate 5 and side plates 6, which makes the indoor unit more stable and facilitates installation and maintenance. The side plates 6 surround the outer perimeter of the base plate 5, forming a closed space to house the components of the indoor unit. The return air surface 4 is located on the side plate 6, meaning air will be drawn in through this surface. This design helps reduce airflow resistance and improve air intake efficiency. The exhaust air surface 3 is located on the base plate 5. This design directs the exhaust airflow towards the bottom, promoting even air distribution and good airflow circulation within the room. The base plate 5, located at the bottom of the housing 1, supports the entire housing 1 and also serves as the exhaust air surface 3, allowing airflow to be discharged directly downwards, facilitating airflow within the room.

[0070] The side panel 6 is located on the side. This layout avoids the air outlet surface 3 and the return air surface 4 being in a position that is directly opposite each other, effectively avoiding direct airflow conflict and improving the efficiency of air circulation.

[0071] Since the air outlet surface 3 and the return air surface 4 are located on different planes, this helps reduce airflow short-circuiting, preventing newly drawn-in air from being immediately expelled, thus improving the energy efficiency of the air conditioner. Furthermore, the smooth airflow also helps reduce noise generated by air movement, providing a quieter indoor environment.

[0072] The bottom plate 5 faces downwards, and the side plate 6 is perpendicular to the surface of the bottom plate 5.

[0073] Setting the bottom plate 5 downwards and making the side plate 6 perpendicular to the bottom plate 5 makes it easier for the bottom plate 5 and the side plate 6 to avoid each other and facilitates air supply.

[0074] Example 3

[0075] Please see Figures 1-2 To further illustrate the structure of the return air surface 4, based on Embodiment 1, this embodiment discloses that the return air surface 4 includes a plurality of air inlet holes 7 evenly distributed on the surface of the side plate 6.

[0076] Since the goal is simply to draw air into the fan 2, it is sufficient to maximize the number of air inlets 7 on the side plate 6. Furthermore, since the air inlets 7 are located on the side plate 6, which has a large area, the number of air inlets 7 can be effectively increased, thus improving air intake efficiency.

[0077] Specifically,

[0078] The return air surface 4 includes several air inlet holes 7 evenly distributed on the surface of the side panel 6. This allows air to be drawn in from multiple locations on the side panel 6, increasing the air intake area and thus improving air intake efficiency.

[0079] Since the purpose of the air inlet 7 is to draw air into the fan 2, opening the air inlet 7 on the side plate 6 to the maximum extent can increase the amount of air drawn in and improve the working efficiency of the air conditioner.

[0080] The side panel 6 has a relatively large area. By evenly arranging the air inlet holes 7 on the side panel 6, the area of ​​the side panel 6 can be fully utilized, the number of air inlet holes 7 can be increased, and the air intake efficiency can be improved.

[0081] The air inlets 7 are evenly distributed on the side plate 6, which ensures that air is drawn in evenly from all directions, reduces the unevenness of local airflow, and improves the stability of airflow.

[0082] By increasing the number of air inlets 7 and optimizing their distribution, air intake efficiency can be improved, which is crucial for the cooling and heating performance of air conditioners.

[0083] The evenly distributed air inlets 7 help reduce noise generated during airflow because air can enter the fan 2 more smoothly, reducing turbulence and eddies.

[0084] Example 4

[0085] Please see Figures 1-2 To further illustrate the air inlet structure, based on Embodiment 1, this embodiment discloses that the air outlet surface 3 includes an air outlet grille, and the air outlet grille is constructed as an air guiding and air outlet structure.

[0086] By constructing the air outlet surface 3 as an air outlet grille with a guiding function, it is easier to improve the feeling of airflow.

[0087] The air guiding and air outlet structure includes an air guide plate 8, on which a plurality of air outlets 9 are started, and the air outlets 9 extend at a set angle.

[0088] This allows the air outlet 9 to have a tilt angle, which enables the air to be discharged in a set direction, thus improving the utilization rate of the air outlet and comfort.

[0089] The air guiding and air outlet structure also includes a rotating shaft, and the core of the air guide plate 8 is located on the rotating shaft, and the air guide plate 8 rotates around the rotating shaft.

[0090] The air guide plate 8 is driven to rotate by the rotating shaft, thereby adjusting the direction of airflow.

[0091] Specifically,

[0092] The air outlet surface 3 includes an air outlet grille, which is constructed as an air-guiding and air-discharging structure. This helps to improve the directionality and uniformity of the airflow, thereby improving the feeling of airflow.

[0093] The air guiding and outlet structure includes an air guide plate 8, on which several air outlets 9 are opened. These air outlets 9 extend at a set angle. This gives the air outlets 9 an inclined angle, which allows the air to be discharged in a set direction, improving air utilization and comfort.

[0094] Rotation of air guide plate 8:

[0095] The air guiding and outlet structure also includes a rotating shaft, on which the core of the air guide plate 8 is located, allowing the air guide plate 8 to rotate around the shaft. This allows the air guide plate 8 to be driven to rotate via the rotating shaft, thereby adjusting the direction of airflow.

[0096] By adjusting the angle of the air guide plate 8, the direction of airflow can be changed to adapt to different indoor environments and user needs. For example, in summer, the airflow direction can be adjusted upwards for better cooling; in winter, the airflow direction can be adjusted downwards for better heating.

[0097] By precisely controlling the airflow direction, energy waste can be reduced and the energy efficiency of air conditioning can be improved.

[0098] By adjusting the airflow direction, direct airflow can be avoided, reducing discomfort and improving user comfort.

[0099] The design of the air deflector 8 should take noise reduction into account, and reduce turbulence and eddies by guiding smooth airflow, thereby reducing noise.

[0100] The rotation of the air guide plate 8 can be combined with the air conditioner's intelligent control system to achieve automatic adjustment via remote control or smart home system.

[0101] The air outlet surface 3 of the indoor unit of the air conditioner ceiling not only provides efficient air circulation, but also can adjust the airflow direction as needed to improve user comfort and air conditioner energy efficiency.

[0102] Example 5

[0103] Please see Figures 1-2 To further illustrate the internal operation of the air conditioning ceiling unit, based on Embodiment 1, this embodiment also discloses a heat exchanger 10, which is located between the return air surface 4 and the fan 2. The gas drawn in by the return air surface 4 enters the fan 2 through the heat exchanger 10.

[0104] The heat exchanger 10 is used to exchange heat with the incoming air, thereby improving the comfort of indoor airflow.

[0105] The heat exchanger 10 includes a heat exchange plate surface, the bottom end of the heat exchange plate is close to the bottom plate 5, and a water receiving tray 12 is provided at the bottom end, with the heat exchange plate placed inside the water receiving tray 12.

[0106] Specifically, the drip tray 12 simply cradles the bottom of the heat exchange plate, and the drip tray 12 drains the condensate through a conduit. In practice, the configuration of the drip tray 12 can be adjusted according to the internal wiring or layout of the air conditioner.

[0107] Specifically,

[0108] The heat exchanger 10 is located between the return air surface 4 and the fan 2. In this way, the gas drawn in from the return air surface 4 first passes through the heat exchanger 10 before entering the fan 2, which helps to improve the efficiency of air temperature regulation.

[0109] The heat exchanger 10 is used to exchange heat with the incoming air, improving the comfort of indoor airflow. In cooling mode, the heat exchanger 10 can lower the air temperature; in heating mode, the heat exchanger 10 can raise the air temperature.

[0110] The heat exchanger 10 includes heat exchange plates, the bottom of which is close to the bottom plate 5 and is provided with a water collection tray 12. This helps to collect the condensate generated during the heat exchange process.

[0111] The drip tray 12 is located at the bottom of the heat exchange plate and is used to collect condensate from the bottom of the heat exchange plate. This prevents condensate from dripping directly into the room, keeping the room dry and clean.

[0112] The condensate drain pan 12 drains the condensate through a conduit. This effectively manages the condensate, preventing water accumulation and potential water damage.

[0113] The configuration of the water tray 12 can be adjusted according to the internal wiring or layout of the air conditioner to adapt to different installation environments and space requirements.

[0114] When designing the heat exchanger 10 and the water tray 12, noise reduction should also be considered to ensure the quiet operation of the air conditioner.

[0115] The working status of heat exchanger 10 can be combined with the intelligent control system of air conditioning to automatically adjust the heat exchange efficiency according to changes in indoor and outdoor temperatures.

[0116] Air conditioning ceiling units not only provide comfortable indoor airflow, but also effectively manage condensate, reduce maintenance costs, and improve the user experience.

[0117] Example 6

[0118] Please see Figures 1-2 To further illustrate the working relationship of the indoor unit of the air conditioner ceiling, based on embodiment 5, this embodiment also discloses a filter screen 11. The filter screen 11 is located between the return air surface 4 and the heat exchanger 10. The gas drawn in by the return air surface 4 flows through the filter screen 11 and then through the heat exchanger 10.

[0119] The filter 11 is used to remove impurities from the air entering the fan 2, thereby improving the cleanliness of the indoor airflow.

[0120] Furthermore, a slot 13 is provided on the base plate 5, and the filter screen 11 is inserted into the slot 13 to achieve fixed positioning.

[0121] Since the heat exchange plate has the function of heat exchange, when the air entering from the return air surface 4 exchanges heat with the heat exchanger 10, the heat exchange plate of the heat exchanger 10 will generate condensate. The water receiving tray 12 is used to receive the condensate and prevent the condensate from leaking out.

[0122] Specifically,

[0123] The filter 11 is located between the return air surface 4 and the heat exchanger 10. In this way, the air drawn in from the return air surface 4 first passes through the filter 11 and then flows through the heat exchanger 10. This arrangement helps to improve the cleanliness of the air.

[0124] The filter 11 is used to remove impurities from the air entering the fan 2, improving the cleanliness of the indoor airflow. This helps reduce dust, bacteria, and other pollutants in the indoor air, thus improving air quality.

[0125] Filter screen 11 fixing method:

[0126] A slot 13 is provided on the base plate 5, and the filter screen 11 is inserted into the slot 13 for fixed positioning. This makes the installation and replacement of the filter screen 11 simple and quick.

[0127] The drip tray 12 is used to collect condensate generated by the heat exchange plates of the heat exchanger 10, preventing condensate leakage. This prevents condensate from dripping directly into the room, keeping the room dry and clean.

[0128] The relationship between the water receiving tray 12 and the heat exchange plate:

[0129] The drip tray 12 is located below the heat exchange plate and directly receives the condensate dripping from the heat exchange plate. This ensures the effective collection and drainage of condensate.

[0130] The condensate drain pan 12 drains the condensate through a conduit. This effectively manages the condensate, preventing water accumulation and potential water damage.

[0131] The filter 11 should be designed to be easy to remove and clean in order to maintain the efficient operation of the air conditioner and good air quality.

[0132] The configuration of the water tray 12 can be adjusted according to the internal wiring or layout of the air conditioner to adapt to different installation environments and space requirements.

[0133] The operating status of the filter 11 and the heat exchanger 10 can be integrated with the intelligent control system of the air conditioner to automatically adjust the heat exchange efficiency and provide cleaning reminders for the filter 11 based on changes in indoor and outdoor temperatures.

[0134] Air conditioning ceiling units not only provide clean indoor airflow, but also effectively manage condensate, reducing maintenance costs and improving the user experience.

[0135] When the whole machine is running, the fan 2 system operates, and the gas enters from the air inlets around the outer shell 1, flows through the filter screen 11 assembly to filter the dust in the air, and then flows into the heat exchanger 10 for heat exchange. Then the gas passes through the fan 2 system and sends the air out from the air outlet grille on the panel to achieve the separation of return air and outlet air, so as to avoid short circuit of the air field and affect the heat exchange effect.

[0136] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.
