Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to a ceiling-mounted air conditioner. Background Technology

[0002] With the improvement of people's living standards, air conditioning has become an indispensable and important device in modern life, widely used in various spaces such as residences, commercial spaces, and industrial plants. Ceiling-mounted air conditioners, with their unique installation method and functional advantages, are gradually gaining market favor. Ceiling-mounted air conditioners typically consist of a unit and a panel. The unit is embedded in the ceiling, concealed within the ceiling, while the panel is installed below the unit and protrudes from the ceiling, providing both concealment of the unit and air exchange between the unit and the room. Ceiling-mounted air conditioners are aesthetically pleasing, do not occupy excessive floor space, and achieve excellent air circulation, thus gaining increasingly widespread application.

[0003] Currently, ceiling-mounted air conditioners on the market have a relatively simple structure, and their main function is to provide basic heating or cooling to meet users' basic temperature control needs. The air outlet of a ceiling-mounted air conditioner is usually designed at the bottom, facing the indoor space below, blowing hot or cold air into the room.

[0004] However, ceiling-mounted air conditioners are limited by traditional structures. Their functional area layout is fixed, space utilization is low, and the single structural form cannot meet the current users' needs for functionality and personalization, which hinders the promotion and application of ceiling-mounted air conditioners. Utility Model Content

[0005] To address the shortcomings of related technologies, this application provides a ceiling-mounted air conditioner that optimizes the panel structure, moves the air outlet to the side, and installs lighting fixtures on the front, thereby improving the zoning utilization of the panel structure and achieving multifunctionality.

[0006] This application provides a ceiling machine, comprising:

[0007] The casing has an air outlet channel inside.

[0008] Panel components, including:

[0009] A first panel, mounted on the casing, has a through-type air guide section that connects to the air outlet duct; and

[0010] The second panel is opposite to the first panel and is installed on the side of the first panel away from the casing;

[0011] An air outlet is defined between the area near the edge of the first panel and the area near the edge of the second panel.

[0012] The air outlet is arranged circumferentially around the panel assembly, and the air outlet is connected to the air guide section;

[0013] The light fixture is installed on the side of the second panel away from the first panel.

[0014] In the above technical solution, by setting a first panel and a second panel, the air outlet is formed between the edges of the first panel and the second panel, creating a surrounding side air outlet. The air outlet area is relatively large, which can meet the air outlet requirements of different air volumes. The air outlet is formed immediately after the first panel and the second panel are assembled, eliminating the need for a guide vane design, thus simplifying the manufacturing process of the air outlet and reducing manufacturing difficulty. In addition, since there is no need to reserve space for the air outlet on the front of the panel assembly, the lighting fixture can be installed on the front, optimizing the zoning utilization of the panel structure and increasing the functionality and personalization of the panel structure.

[0015] In some embodiments, the first panel and the second panel are mounted concentrically, and the edge of the second panel is positioned closer to the center than the edge of the first panel.

[0016] In the above technical solution, the edge of the second panel is recessed towards the center relative to the edge of the first panel. This design makes part of the air outlet face the user, which is more conducive to the airflow flowing out of the air outlet spreading rapidly in a direction closer to the user, thereby improving the uniformity of indoor heat exchange.

[0017] In some embodiments, an air intake channel is also formed inside the housing; an air inlet is formed through the middle area of ​​the first panel and the second panel, and the air inlet is connected to the air intake channel.

[0018] In the above technical solution, the air inlet of the indoor unit runs through the front of the panel assembly, so that the indoor return air does not need to be turned and can directly and smoothly enter the air intake channel inside the casing, effectively improving the air intake efficiency and heat exchange efficiency.

[0019] In some embodiments, the panel assembly further includes a lamp carrier panel opposite to the second panel, the lamp carrier panel being mounted on the side of the second panel away from the first panel, and a mounting portion for mounting a lamp is formed on the lamp carrier panel.

[0020] In the above technical solution, the panel assembly is provided with a separate lamp carrier panel for installing lamps. The lamp carrier panel is located on the outside of the panel assembly, that is, the side facing the user. The lamps can be observed by the user more intuitively. When used as indicator lights, they can quickly obtain key information such as the air conditioner's operating status and mode switching, thereby improving the convenience of human-computer interaction.

[0021] In some embodiments, the lamp panel forms a ventilation section corresponding to the air inlet, so that indoor return air enters the air inlet through the ventilation section. The ventilation section allows airflow to pass through, so that indoor return air can pass through the ventilation section and enter the housing through the air inlet for heat exchange.

[0022] In some embodiments, the luminaire includes multiple annular light strips; the mounting portion includes multiple annular recesses located outside the ventilation portion, each annular recess containing an annular light strip.

[0023] In the above technical solution, the annular recessed design of the installation part can avoid the ventilation part located in the middle area, and at the same time, it can make fuller use of the space of the light-carrying panel and increase the installation area of ​​the light fixture; the light fixture is correspondingly designed as a ring light strip, and when lit, the front of the panel component forms a ring of light effect, which can not only improve the indication effect for users, but also increase the aesthetics of the air conditioner indoor unit and enhance the product competitiveness.

[0024] In some embodiments, the multiple ring-shaped light strips are divided into a first group of ring-shaped light strips and a second group of ring-shaped light strips, with each ring-shaped light strip in each group arranged continuously.

[0025] In the above technical solution, the ring light strip is divided into two groups. Based on the different states of the two groups of ring light strips, or their different states of cooperation, the types of prompts for information such as air conditioner operation status and mode switching are increased, thereby improving the user experience.

[0026] In some embodiments, a first lampshade is installed outside the first group of annular light strips, and a second lampshade is installed outside the second group of annular light strips.

[0027] In the above technical solution, lamp covers are installed on the first and second sets of ring-shaped light strips respectively to protect the two sets of ring-shaped light strips, allowing for easy individual disassembly and maintenance. Furthermore, the separate design of the first and second lamp covers allows them to be made of different colors and / or different materials, increasing the diversity and aesthetics of the air conditioner indoor unit.

[0028] In some embodiments, a filter is installed inside the air inlet for filtering indoor return air.

[0029] In the above technical solution, the filter can intercept dust and various particles in the indoor return air, preventing them from entering the casing and adhering to the surface of components such as heat exchangers and fans. This reduces the risk of equipment performance degradation due to scale buildup, lowers the probability of disassembly and maintenance, and extends the service life of the equipment.

[0030] This application also provides a ceiling machine, comprising:

[0031] The casing has an air outlet channel inside.

[0032] The panel assembly is mounted on the housing, and an air outlet is formed around the circumference of the panel assembly. The air outlet is connected to the air outlet channel. The side of the panel assembly away from the housing is the visible side.

[0033] Lighting fixtures, installed on the visible side, are used to indicate the working status.

[0034] In the above technical solution, the air outlet is located on the side of the panel assembly, forming a surrounding side air outlet. The air outlet area is relatively large, which can meet the air outlet requirements of different air volumes. The visible side of the panel assembly no longer needs to reserve space for the air outlet, so more space can be reserved to install lights to indicate the working status of the air conditioner. This helps to improve the prompting effect for users, avoid user misjudgment, and also allows for more space for personalized design, improving the practicality and aesthetics of the ceiling unit.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0053] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

The terms "first," "second," "third," etc., used in this application are merely to distinguish similar objects and do not represent a specific ordering of objects.

[0055] With the continuous development of air conditioning technology, ceiling-mounted air conditioners have emerged. Ceiling-mounted units are typically installed in the ceiling of an interior space; for example, the unit itself is embedded in the ceiling, with the panel located below the unit and protruding from the ceiling. This installation method does not occupy floor space, providing greater flexibility in the use of interior space, and is particularly suitable for locations with limited space.

[0056] The air outlets of existing ceiling air conditioners are usually located at the bottom, blowing hot or cold air directly into the indoor space below to meet the indoor temperature regulation needs.

[0057] However, existing ceiling-mounted ceiling systems have a simple structure, with fixed structures in each functional area and low space utilization, which makes it impossible to further improve their functionality and personalization, thus hindering the further development of ceiling-mounted ceiling systems.

[0058] Based on this, this application proposes a ceiling-mounted air conditioner that optimizes the panel structure by moving the air outlet to the side, allowing ample space on the front of the panel for lighting fixtures, thus improving space utilization, integrating more functions, increasing the functionality of the ceiling-mounted air conditioner, and enabling various personalized designs on the front to meet the individual needs of different users and enhance the market competitiveness of the ceiling-mounted air conditioner.

[0059] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0060] like Figures 1-4 As shown in the figure, the ceiling air conditioner provided in this application embodiment includes a housing 100. Typically, the housing 100 is embedded in the indoor ceiling, reducing space occupation and improving aesthetics.

[0061] To enable the hoisting of the housing 100, various hoisting components, such as the hoisting lug 103, can be installed on the housing 100 according to installation requirements, thereby hoisting the entire ceiling unit to the indoor ceiling.

[0062] like Figure 4 and Figure 5 As shown, a heat exchanger 300 is installed inside the housing 100. The heat exchanger 300 is used to exchange heat with the air flowing into the housing 100 to achieve cooling or heating functions.

[0063] The heat exchanger 300 includes heat dissipation pipes and fins. The heat dissipation pipes are arranged in a serpentine or spiral path inside the housing 100, and the fins are fitted on the outer surface of the heat dissipation pipes to increase the heat exchange area with the surrounding environment.

[0064] When in cooling mode, the heat exchanger 300 of the ceiling unit acts as an evaporator. The low-temperature, low-pressure liquid refrigerant in the cooling circuit enters the evaporator and is converted into gaseous refrigerant, absorbing heat from the surrounding environment, thereby cooling the air entering the casing 100.

[0065] When in heating mode, the heat exchanger 300 of the ceiling unit acts as a condenser. The high-temperature and high-pressure gaseous refrigerant in the refrigeration circuit enters the condenser and is transformed into liquid refrigerant, releasing heat to the surrounding environment, thereby raising the temperature of the air entering the casing 100.

[0066] like Figure 5 As shown, a fan 400 is also installed inside the casing 100. The fan 400 includes an inlet side and an outlet side. Indoor return air is drawn into the casing 100 through the inlet side of the fan 400, changes direction under the drive of the fan 400, and is blown towards the heat exchanger 300 through the outlet side of the fan 400 to exchange heat with the heat exchanger 300. The speed of the fan 400 can be adjusted according to actual needs to meet different air volume and heat exchange requirements.

[0067] like Figure 4 and Figure 5 As shown, an air outlet channel 101 is formed inside the casing 100. After heat exchange by the heat exchanger 300, the airflow is blown out of the casing 100 through the air outlet channel 101 under the drive of the fan 400.

[0068] The ceiling unit also includes a panel assembly 200. For example... Figures 1-5 As shown, the panel assembly 200 is mounted on the housing 100. The panel assembly 200 is a user-facing component that integrates air supply and return functions.

[0069] In the recessed installation state of the ceiling unit, the housing 100 is located inside the ceiling, the panel assembly 200 is located below the housing 100, and the panel assembly 200 is exposed outside the ceiling.

[0070] Based on the problems raised in the prior art, this application optimizes the structure of the panel assembly 200, which is described below through two embodiments.

[0071] In the first embodiment of the improvement to panel assembly 200, such as Figures 1-10 As shown, the panel assembly 200 includes a first panel 210 and a second panel 220.

[0072] The first panel 210 is mounted on the housing 100, and a guide section 211 is formed through the first panel 210, which is connected to the air outlet channel 101.

[0073] The second panel 220 is opposite to the first panel 210 and is mounted on the side of the first panel 210 away from the housing 100.

[0074] An air outlet 201 is defined between the area near the edge of the first panel 210 and the area near the edge of the second panel 220. The air outlet 201 is arranged circumferentially around the panel assembly 200 and is connected to the air outlet channel 101 inside the housing 100.

[0075] In the above embodiment, the first panel 210 and the second panel 220 are stacked together with their surfaces facing each other. The air outlet 201 is formed between the edges of the first panel 210 and the second panel 220, forming a side-mounted air outlet. The air outlet 201 has a large area, which can meet the air outlet requirements of different air volumes. The air outlet 201 is formed by assembling the first panel 210 and the second panel 220, eliminating the need for a guide plate, simplifying the manufacturing process of the air outlet 201 and reducing manufacturing difficulty. In addition, since there is no need to reserve space for the air outlet 201 on the front of the panel assembly 200, more space can be reserved for personalized design, improving the practicality and aesthetics of the ceiling machine.

[0076] In some embodiments, a lamp is mounted on the side of the second panel 220 away from the first panel 210.

[0077] The lighting fixture can have illumination or indicator functions, or both, and can be designed according to user needs. This embodiment does not impose any restrictions. When the lighting fixture is used as an indicator, it is used to indicate the working status of the ceiling-mounted unit of this application. For example, the user can be prompted with different working statuses such as the current heating or cooling status and airflow level through the switching on and off of indicator lights and color changes.

[0078] In a second embodiment of the improvement to panel assembly 200, such as Figures 1-10 As shown.

[0079] An air outlet 201 is formed around the circumference of the panel assembly 200, and the air outlet 201 is connected to the air outlet channel 101; the side of the panel assembly 200 away from the housing 100 is the visible side.

[0080] Lights are installed on the visible side to indicate the working status.

[0081] In the above implementation, the air outlet 201 is located on the side of the panel assembly 200, forming a surrounding side air outlet. The air outlet 201 has a large area, which can meet the air outlet requirements of different air volumes. The visible side of the panel assembly 200 does not need to reserve space for the air outlet 201, so more space can be reserved to install lights for indicating the working status of the air conditioner. This helps to improve the prompting effect for users, avoid user misjudgment, and also allows for more space for personalized design, improving the practicality and aesthetics of the ceiling unit.

[0082] Optionally, the panel assembly 200 in the above embodiments includes a first panel 210 and a second panel 220 in the first embodiment.

[0083] It is understood that the structures of the panel assembly 200 defined by the above two embodiments may overlap, and should not be construed as being mutually exclusive.

[0084] The technical features of the ceiling machine are further described below. It should be noted that the solutions described in the following embodiments are also applicable to ceiling machines with panel assemblies including the above two embodiments.

[0085] In some embodiments, such as Figure 2 and Figure 3 As shown, on the projection surface facing the user, the size of the panel assembly 200 is larger than the size of the housing 100, so that the housing 100 on the back can be covered by the front facing the user, effectively hiding the structure of the housing 100 and improving the aesthetics.

[0086] In some embodiments, such as Figure 8 As shown, in panel assembly 200, first panel 210 and second panel 220 are concentrically mounted, and the edge of second panel 220 is positioned closer to the center than the edge of first panel 210.

[0087] In the above embodiment, the edge of the second panel 220 is recessed towards the center relative to the edge of the first panel 210. This design causes part of the opening of the air outlet 201 to face the user, which is more conducive to the rapid diffusion of the airflow from the air outlet 201 towards the user, thereby improving the uniformity of indoor heat exchange. Optionally, the first panel 210 and the second panel 220 are circular in shape.

[0088] In some embodiments, multiple air guide sections 211 are provided, and the multiple air guide sections 211 are distributed at intervals on the first panel 210. To facilitate the air guiding function of the air guide sections 211, the air guide sections 211 can be designed to face the air outlet channel 101.

[0089] For example, in some embodiments, such as Figure 10As shown, there are four air guides 211, which are located at the four positions of the first panel 210. Each air guide 211 extends along the length of the air outlet channel 101.

[0090] In some embodiments, such as Figure 6 and Figure 10 As shown, a guide plate 212 is provided at the air guide section 211, and the guide plate 212 extends from the edge of the air guide section 211 near the outer side of the first panel 210 into the air outlet channel 101.

[0091] Under the guidance of the baffle plate 212, the airflow in the air outlet duct 101 can flow smoothly to the air guide section 211, reducing the generation of turbulence, improving air outlet efficiency and air delivery effect, and enhancing user experience.

[0092] In some embodiments, such as Figure 5 and Figure 6 As shown, the heat exchanger 300 has an annular structure and is fitted outside the fan 400; an air outlet channel 101 is formed between the heat exchanger 300 and the casing 100.

[0093] The air guide section 211 is located in the area between the heat exchanger 300 and the casing 100 on the first panel 210, and is thus directly corresponding to the air outlet 101, which is conducive to the airflow after heat exchange entering the air outlet 201 more smoothly through the air guide section 211.

[0094] In some embodiments, such as Figure 4 and Figure 5 As shown, the air inlet side of the fan 400 faces the panel assembly 200, and the air outlet side of the fan 400 faces the heat exchanger 300.

[0095] like Figures 7-9 As shown, an air intake channel 102 is also formed inside the housing 100. An air inlet 202 is formed through the middle area of ​​the first panel 210 and the second panel 220, and the air inlet 202 is connected to the air intake channel 102.

[0096] In the above embodiment, the indoor return air enters the air inlet side of the fan 400 through the air inlet 202, passes through the panel assembly 200, is blown out by the air outlet side of the fan 400 and exchanges heat with the heat exchanger 300, and then enters the room through the air outlet 201.

[0097] The air inlet 202 of the indoor unit runs through the front of the panel assembly 200, so that the indoor return air does not need to be turned and can directly and smoothly enter the casing 100. The return air entering the casing 100 is changed in direction by the impeller of the fan 400 and blown towards the heat exchanger 300 for heat exchange, effectively improving the air intake efficiency and heat exchange efficiency.

[0098] In some embodiments, such as Figure 9As shown, a filter section 203 is installed inside the air inlet 202, which is used to filter the indoor return air.

[0099] The filter section 203 intercepts dust and various debris in the indoor return air, preventing them from entering the casing 100 and adhering to the surfaces of components such as the heat exchanger 300 and fan 400. This reduces the risk of equipment performance degradation due to scale buildup, lowers the probability of disassembly and maintenance, and only requires periodic cleaning of the filter section 203, facilitating routine maintenance and extending the equipment's lifespan. The filter section 203 can be a filter screen.

[0100] In some embodiments, such as Figures 1-9 As shown, the panel assembly 200 also includes a lamp carrier panel 230, which is opposite to the second panel 220 and is mounted on the side of the second panel 220 away from the first panel 210. A mounting portion for mounting a lamp is formed on the lamp carrier panel 230.

[0101] In the above embodiment, the panel assembly 200 is provided with a separate lamp carrier panel 230 for mounting lamps. The lamp carrier panel 230 is located on the outside of the panel assembly 200, that is, on the side facing the user. The lamps can be observed by the user more intuitively. When used as an indicator light, it can quickly obtain key information such as the air conditioner's operating status and mode switching, thereby improving the convenience of human-computer interaction.

[0102] By setting up a separate lamp carrier panel 230, different types of lamp carrier panels 230 can be assembled according to different user needs during assembly and maintenance, improving the adaptability of the panel assembly 200. Moreover, the lamp carrier panel 230 can be disassembled separately for repair or replacement during subsequent maintenance, extending the service life of the panel assembly 200.

[0103] In some embodiments, the lamp panel 230 forms a ventilation section 232 corresponding to the air inlet 202, and indoor return air enters the air inlet 202 through the ventilation section 232. The ventilation section 232 allows airflow to pass through, so that indoor return air can pass through the ventilation section 232 and enter the interior of the housing 100 for heat exchange through the air inlet 202.

[0104] The design of the ventilation section 232 can prevent the light carrier panel 230 from blocking the air inlet 202. Even if the light carrier panel 230 has a large area, it will not have an adverse effect on the air intake function. This provides greater flexibility for the design of the light carrier panel 230, and its area can be expanded according to actual needs, which is conducive to the personalized design of the ceiling machine.

[0105] Furthermore, the specific structure of the ventilation section 232 can be designed as needed.

[0106] In some embodiments, the ventilation section 232 is a hollow structure with multiple ventilation holes, the shape and number of which can be designed to combine ventilation function and aesthetics.

[0107] For example, the ventilation section 232 can be formed as a honeycomb-shaped perforated structure, or it can be formed as a perforated structure with rectangular ventilation holes.

[0108] In some embodiments, such as Figures 11-13 As shown, the luminaire includes multiple annular light strips 500; the mounting part includes multiple annular recesses 231 located outside the ventilation part 232, and each annular recess 231 is provided with an annular light strip 500.

[0109] The annular recessed portion 231 of the mounting section avoids the ventilation portion 232 located in the central area, while also making fuller use of the space of the light-carrying panel 230, increasing the installation area of ​​the light fixture. The light fixture is correspondingly designed as a ring-shaped light strip 500. When illuminated, the front of the panel assembly 200 forms a ring of light, which not only enhances the user's visibility but also increases the aesthetics of the air conditioner indoor unit, improving product competitiveness. Optionally, the ring-shaped light strip 500 can be an LED light strip.

[0110] In some embodiments, such as Figure 13 As shown, the multiple ring-shaped light strips 500 are divided into a first group of ring-shaped light strips 510 and a second group of ring-shaped light strips 520, with each ring-shaped light strip 500 in each group of ring-shaped light strips 500 arranged continuously.

[0111] Dividing the ring light strip 500 into two groups allows for the use of the two groups in coordination. Depending on the different states of the two groups of ring light strips 500, or their different states in combination, the types of prompts for information such as air conditioner operation status and mode switching can be increased, thereby improving the user experience.

[0112] In some embodiments, lighting effects are used to indicate the operating mode when switching modes.

[0113] The first set of ring-shaped light strips 510 is located in the inner ring, and the second set of ring-shaped light strips 520 is located in the outer ring. When the air conditioner is in cooling mode, the first set of ring-shaped light strips 510 in the inner ring emits warm light, and the second set of ring-shaped light strips 520 in the outer ring emits cool light, giving users the visual impression of a cool breeze.

[0114] When the air conditioner is in heating mode, the first set of inner ring light strips 510 emits cool-colored light, and the second set of outer ring light strips 520 emits warm-colored light, giving users the impression of hot air being blown; in non-cooling and non-heating modes, both the first set of ring light strips 510 and the second set of ring light strips 520 emit neutral light.

[0115] In some embodiments, light effects are used to indicate the airflow when adjusting the airflow.
