Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0055] This invention proposes a radiation module 1000, which aims to achieve rapid external heating by radiating infrared rays, thereby improving the efficiency of thermal radiation. It is understood that the radiation module 1000 proposed in this invention can be applied to any electrical device that needs to release heat outwards, and is not limited to any specific device.

[0056] The following explanation uses the application of the radiant module 1000 to an air conditioner indoor unit as an example: When the radiant module 1000 is applied to an air conditioner indoor unit, it can quickly heat the indoor environment to compensate for the heating process when the air conditioner indoor unit is turned on in heating mode, and at the same time improve the temperature stratification of the space.

[0057] In embodiments of the present invention, such as Figures 1 to 10 As shown, the radiation module 1000 includes a mounting shell 110, a heating element 120, and a first reflective layer 130.

[0058] The mounting housing 110 has an opening 101; the heating element 120 is disposed inside the mounting housing 110 for radiating infrared rays; the first reflective layer 130 is disposed inside the mounting housing 110 for reflecting infrared rays out of the opening 101.

[0059] The mounting housing 110 serves to fix and mount the heating element 120. The mounting housing 110 has an opening 101 so that the infrared rays radiated by the heating element 120 can be emitted from the opening 101 to the outside of the mounting housing 110, thereby enabling the radiation module 1000 to radiate infrared rays in the desired direction to heat the air or structure at the desired location.

[0060] The mounting housing 110 is provided with a first reflective layer 130. The first reflective layer 130 can reflect the infrared rays it receives to the opening 101 and emit them from the opening 101, thereby reducing the loss of infrared rays radiated by the heating element 120 and preventing the mounting housing 110 from being heated and affecting the structural reliability. It is understood that the setting position of the first reflective layer 130 can be determined according to the actual situation. It can be set only on the side of the heating element 120 away from the opening 101, that is, on both sides of the heating element 120 opposite to the opening 101, so as to directly reflect the infrared rays to the opening 101; or, the first reflective layer 130 can cover the entire area of ​​the mounting housing 110 except for the opening 101, so as to receive all infrared rays except for the opening 101, and after a single reflection on one side or multiple reflections on multiple sides, emit them from the opening 101 into the external space, thereby improving the utilization rate of infrared rays and preventing infrared rays from directly acting on the mounting housing 110.

[0061] In practical applications, the first reflective layer 130 can be directly attached to the inner wall of the mounting shell 110, or it can be spaced apart from the mounting shell 110, or the mounting shell 110 and the first reflective layer 130 can be an integral structure, with the mounting shell 110 itself possessing reflective function. To ensure good reflective effect, the first reflective layer 130 can be a smooth metal, such as stainless steel, aluminum, silver, copper, etc., or it can be a polyester or polyimide film with a metal-plated mounting surface.

[0062] In this embodiment, the heating element 120 is a far-infrared heating element, which can be silicon carbide, metal tube, quartz tube, carbon fiber, graphene, etc. Its basic composition can be a layer of high-temperature resistant quartz glass wrapped around carbon fiber, with a vacuum formed in the middle of the glass to create a certain negative pressure. Shock-absorbing springs are installed at both ends of the carbon fiber. The wavelength range of far-infrared rays is 1.5 micrometers to 400 micrometers, which is invisible light. Therefore, it will not affect the user's eyes during application, especially at night or in dimly lit spaces, ensuring user safety.

[0063] Understandably, when the radiant module 1000 is used in an indoor air conditioning unit, it can be installed inside or outside the casing 2000. When installed inside the housing 2000, the radiant module 1000 can be movably connected to the housing 2000, allowing it to move out from inside the housing 2000 when the indoor unit is in heating mode to emit infrared rays into the indoor environment, rapidly heating the indoor temperature. When installed outside the housing 2000, the radiant module 1000 can be fixedly connected to the housing 2000, radiating infrared rays to the front or lower side of the indoor unit to heat the air there and prevent temperature stratification. The radiant module 1000 can also be movably connected relative to the housing 2000. When the indoor unit is in heating mode, the radiant module 1000 can be adjusted to a preset position to heat the air in the desired location. After heating for a certain period, the position of the radiant module 1000 can be adjusted again to heat the air in other locations, further improving the uniformity of indoor air temperature distribution.

[0064] It should be noted that the operating state of the radiant module 1000 is determined by the operating state of the indoor unit of the air conditioner. For example, when the indoor unit is in heating mode, turning on the radiant module 1000 can accelerate the heating effect, and the radiant direction of the radiant module 1000 can improve the phenomenon of temperature stratification in the indoor space. However, in cold winters, after the air conditioner has been running in heating mode for a period of time, frost may form on the outdoor unit. At this time, the air conditioner can be switched to cooling mode or the heating mode can be stopped. The indoor unit may blow out cold air, causing fluctuations in the indoor temperature. Turning on the radiant module 1000 at this time can prevent temperature fluctuations caused by defrosting and improve user comfort.

[0065] In practical applications, the radiation module 1000 is connected to the housing 2000 via the mounting shell 110. The connection between the mounting shell 110 and the housing 2000 can be a fixed connection, a sliding connection, or a rotating connection. The radiation direction of the radiation module 1000 is outward from the housing 2000 to heat the air in the indoor environment.

[0066] In the radiation module 1000 of this invention, a heating element 120 is installed inside a mounting housing 110 and is capable of radiating infrared rays. The mounting housing 110 has an opening 101 so that the infrared rays radiated by the heating element 120 can be emitted out through the opening 101 to quickly heat the air or structure at the desired location. A first reflective layer 130 is provided inside the mounting housing 110. This first reflective layer 130 can reflect the infrared rays to the opening 101 and emit them out through the opening 101, reducing the loss of infrared rays and improving the efficiency of the radiation module 1000 in radiating heat outwards. In this embodiment, when the radiation module 1000 is applied to an indoor air conditioning unit, it can achieve rapid heating upon startup, improve spatial air temperature stratification, and reduce air temperature fluctuations, thereby enhancing user comfort.

[0067] To further improve infrared radiation efficiency, refer to Figures 2 to 5 as well as Figures 7 to 10 In one embodiment of the present invention, the radiation module 1000 further includes a radiation panel 140 disposed at the opening 101, the radiation panel 140 having a radiation surface 141 facing outward of the mounting housing 110.

[0068] Understandably, the heating element 120 is located inside the mounting housing 110. The heating element 120 radiates infrared rays in the form of radiation radiating outwards from the heating element 120 as the center. By installing a radiation panel 140 at the opening 101 of the mounting housing 110, the radiation panel 140 can absorb the heat inside the mounting housing 110 and radiate infrared rays to the outside of the mounting housing 110 through the radiation surface 141. Compared with the heating element 120 itself, the radiation center area of ​​the infrared rays is increased.

[0069] Meanwhile, since the infrared rays emitted by the heating element 120 may be unevenly distributed when they reach the opening 101 after being reflected by the first reflective layer 130 inside the mounting shell 110, resulting in uneven temperature at the opening 101, the radiating panel 140 can conduct temperature within the mounting shell 110 after absorbing the infrared rays inside, so as to uniformly distribute the temperature and achieve a uniform temperature distribution on the radiating surface 141, thereby achieving the effect of uniformly radiating heat outward from the radiating surface 141.

[0070] In practical applications, the radiation panel 140 is installed at the opening 101. In addition to uniformly controlling the temperature, it can also soften the infrared rays emitted by the heating element 120. Furthermore, the radiation panel 140 can completely block the opening 101 to prevent insects from entering the mounting housing 120, and also avoids the risk of the heating element 120 being damaged and falling when the radiation module 1000 is installed at a high place.

[0071] In one embodiment of the present invention, the radiating surface 141 is a plane or a convex arc surface protruding outward from the mounting shell 120.

[0072] Understandably, when the radiating surface 141 is planar, the heating function of the desired location can be achieved by adjusting the orientation of the radiating surface 141 in the radiating module 1000. For example, when the indoor unit of the air conditioner is located at a high position, the orientation of the radiating surface 141 can be adjusted to face downwards or downwards to the front. When the radiating surface 141 is a convex arc surface, the radiation range is expanded compared to a planar surface, thus achieving a larger heat radiation range effect with only a small adjustment of the radiating module 1000.

[0073] To further enhance the reflection effect, refer to Figures 1 to 10 In one embodiment of the present invention, the surface of the first reflective layer 130 opposite to the opening 101 is configured as a plane or a concave arc surface.

[0074] Understandably, the first reflective layer 130 can be disposed on the surface of the mounting housing 110 opposite to the opening 101, or it can be disposed on the side of the opening 101, with the purpose of reflecting infrared rays that do not exit the opening 101. In this embodiment, the surface of the first reflective layer 130 opposite to the opening 101 can be set as a plane or a concave arc surface to ensure the reflection effect of infrared rays toward the opening 101.

[0075] In practical applications, when infrared rays emitted from the heating element 120 reach the surface of the first reflective layer 130 opposite to the opening 101, the concave arc surface design allows the infrared rays reflected by the first reflective layer 130 to be directed parallel to the opening 101, thus avoiding energy loss caused by multiple reflections of the infrared rays within the mounting housing 110.

[0076] Based on the aforementioned embodiment, the radiation panel 140 is located at the opening 101, so that the infrared rays reflected by the first reflective layer 130 provided by the concave arc surface can directly enter the radiation panel 140 in parallel, further improving the uniformity of radiation from the radiation surface 141.

[0077] It should be noted that the improvement in this embodiment is made to the surface of the first reflective layer 130 opposite to the opening 101. It does not affect the surface where the first reflective layer 130 is connected to the mounting shell 110, nor does it affect the structural shape of the mounting shell 110 itself. In practical applications, the outer surface of the mounting shell 110 can be flat, concave, or convex, and its specific shape can be related to the installation occasion, such as the structural setting to match the indoor unit of an air conditioner.

[0078] To further improve the directionality of the outward radiation of the radiation module 1000, refer to Figures 3 to 5 as well as Figures 8 to 10In one embodiment of the present invention, a second reflective layer 150 is provided on the side of the heating element 120 away from the opening 101, and the second reflective layer 150 is located between the heating element 120 and the first reflective layer 130.

[0079] Understandably, the second reflective layer 150 is located between the first reflective layer 130 and the heating element 120, and the second reflective layer 150 serves to further reflect infrared rays to the opening 101.

[0080] In this embodiment, the second reflective layer 150 can be set as a reflective coating on the surface of the heating element 120 away from the opening 101. Optionally, it can be achieved by silver plating on the surface of the heating element 120, which enhances the directionality of radiation toward the opening 101 and can reduce the temperature of the mounting shell 110 to ensure structural stability.

[0081] In one embodiment of the present invention, reference is made to... Figures 1 to 10 A heat insulation layer 160 is provided between the mounting shell 110 and the first reflective layer 130.

[0082] Understandably, the insulation layer 160 serves as a heat insulation layer between the mounting shell 110 and the first reflective layer 130, preventing the mounting shell 110 from conducting high temperatures to the components it is mounted on, such as the casing 2000 of the indoor air conditioner or the air duct. In addition to reflecting infrared rays, the first reflective layer 130 also helps to reduce the heat transfer temperature of the insulation layer 160.

[0083] In practical applications, the insulation layer 160 is made of heat-insulating material, which is preferably foam plastic (polyurethane (PUR), polystyrene (PS), polyvinyl chloride (PVC), polyethylene (PE), phenolic resin (PF), etc.). The insulation layer 160 and the first reflective layer 130 can be installed by adhering a smooth metal aluminum foil or silver foil to the surface of the insulation layer 160, or by coating the surface of the insulation layer 160 with a metal polyester or polyimide film, etc.

[0084] To ensure optimal thermal radiation performance, refer to Figures 1 to 10 In one embodiment of the present invention, when the radiation module 1000 is in the on state, the temperature T of the radiation surface 141 is not less than 60°C.

[0085] Understandably, the radiation module 1000 heats the air or structure in the desired area by emitting infrared rays. Therefore, to ensure effective thermal radiation, the radiation module 1000 should ideally be a high-temperature radiation module, with the temperature T of the radiation surface 141 ≥ 60℃. In practical applications, the preferred temperature of the radiation surface 141 is [80℃, 250℃], ensuring effective thermal radiation while avoiding damage to its components due to excessive temperature. Furthermore, a contact-type temperature sensor can be installed on the radiation surface 141 to control the operation of the heating element 120 and maintain the temperature of the radiation surface 141.

[0086] In one embodiment, when the radiation module 1000 is in the on state, the temperature T of the radiation surface 141 and the area S of the radiation surface 141 satisfy: T / S ≥ 15 (℃ / m²). 2 In this embodiment, the area S of the radiating surface 141 and the temperature T of the radiating surface are configured in a certain ratio, with the ratio of the temperature T of the radiating surface 141 to the area S of the radiating surface 141 ≥ 15 (°C / m²). 2 When the radiant surface 141 has an area S ≥ 0.4m², the temperature regulation effect on the air within the space covered by its radiant heat is better. Optionally, the radiant surface 141 area S ≥ 0.4m² 2 .

[0087] Understandably, when the radiant module 1000 is applied to an indoor air conditioner unit, it can be turned on when the indoor air conditioner unit is in heating or defrosting mode. By using the relationship between the temperature T and area S of the radiant surface 141, the radiant efficiency of the radiant module 1000 can be guaranteed, thereby further improving the heating efficiency of the indoor environment.

[0088] In one embodiment of the present invention, reference is made to... Figures 1 to 10 The radiation module 1000 also includes a mesh cover 170 covering the opening 101, and the mesh cover 170 is fastened to the mounting shell 110.

[0089] It is understandable that the radiation module 1000 radiates heat outward, and the temperature of its radiation surface 141 is relatively high. In this embodiment, a mesh cover 170 is provided at the opening 101 to prevent users from accidentally touching it and getting burned. At the same time, it can also prevent large external impurities from entering the mounting shell 110 and damaging the radiation panel 140 or the heating element 120.

[0090] The mesh cover 170 and the mounting shell 110 are fastened together for easy disassembly and assembly by the user.

[0091] In one embodiment of the present invention, reference is made to... Figures 1 to 10The mounting shell 110 includes a back plate 111 and a side plate 112 surrounding the periphery of the back plate 111. The back plate 111 and the side plate 112 together form a cavity for accommodating the heating element 120. The side plate 112 opposite to the back plate 111 forms the opening 101. The mesh cover 170 is fastened to the side plate 112.

[0092] In this embodiment, the back plate 111 is disposed opposite to the opening 101 and is respectively disposed on both sides of the heating element 120. The side plate 112 is disposed around the periphery of the back plate 111 to form a shell structure that protects the heating element 120.

[0093] Understandably, since the area of ​​the first reflective layer 130 opposite to the opening 101 is located on the back plate 111, the back plate 111 can be configured as a concave arc structure. A reflective layer can be deposited on the back plate 111 so that the surface of the first reflective layer 130 opposite to the opening 101 is a concave arc surface, thereby enhancing the reflection effect. Furthermore, the side plate 112 is also covered with the first reflective layer 130 to prevent infrared rays from heating the side plate 112, which could cause the side plate temperature to become too high and affect the structural reliability.

[0094] The side panel 112 is fastened to the mesh cover 170, ensuring installation space for the heating element 120 and providing sufficient reflection space for infrared rays within the mounting housing 110. Optionally, the mesh cover 170 consists of a frame 171 and a grille 172 mounted on the frame 171. The frame 171 is mated to the side panel 112, and the grille 172 is opposite to the back panel 111. The back panel 111, side panel 112, frame 171, and grille 172 together form a complete cavity. The radiation panel 140 can be positioned on the side of the side panel 112 away from the back panel 111, thus sealing the cavity of the mounting housing 110. At the same time, the grille 172 prevents accidental contact with the radiation panel 140.

[0095] Optionally, the outer wall of the side panel 112 is provided with a first fastener 113, and the outer wall of the mesh cover 170 is provided with a second fastener 173. The first fastener 113 and the second fastener 173 are fastened together. It can be understood that since the side panel 112 and the cover frame 171 are mated together, the second fastener 173 can be disposed on the outer wall of the cover frame 171. The installation of the side panel 112 and the cover frame 171 is achieved by fastening the first fastener 113 and the second fastener 173 together, thereby realizing the installation of the mounting shell 110 and the mesh cover 170.

[0096] In one embodiment of the present invention, reference is made to... Figures 6 to 10 The radiation module 1000 includes at least two connected mounting shells 110, and a ventilation hole 180 is formed between two adjacent mounting shells 110;

[0097] Each of the mounting housings 110 is provided with a corresponding heating element 120.

[0098] Understandably, when the radiant module 1000 is installed in the air duct or air outlet of the indoor unit of the air conditioner, in order to ensure smooth airflow, the radiant module 1000 may include at least two connected mounting shells 110, and the two adjacent mounting shells 110 are spaced apart to form ventilation holes 180. Each mounting shell 110 is provided with a heating element 120 and a mesh cover 170, so as to achieve ventilation while ensuring the effect of heat radiation.

[0099] Optionally, the ventilation hole 180 can penetrate the mounting housing 110 and the mesh cover 170, allowing airflow to flow from the outside of the grille 172 to the outside of the back panel 111. In application, the radiant module 1000 can be located at the air inlet of the indoor unit of the air conditioner, and the ventilation hole 180 can serve as an air inlet channel. The radiant module 1000 can heat the incoming airflow to reduce the temperature difference between the incoming and outgoing air, thereby reducing the heating energy consumption of the indoor unit of the air conditioner and improving energy efficiency.

[0100] It should be noted that the radiation module 1000 in this embodiment is equivalent to having multiple sub-radiation units, and the ventilation hole 180 separates two adjacent sub-radiation units. Each sub-radiation unit is an independent radiation unit, which may include a mounting shell 110, a heating element 120 and a first reflective layer 130, or may include a mounting shell 110, a heating element 120, a first reflective layer 130 and a radiation panel 140, or may include a mounting shell 110, a heating element 120, a first reflective layer 130, a radiation panel 140 and a second reflective layer 130.

[0101] In practical applications, the ventilation holes 180 of the radiation module 1000 can be strip-shaped, circular, or diamond-shaped, etc.

[0102] In one embodiment, the at least two mounting shells 110 are an integral structure; the at least two mesh covers 170 are an integral structure. In this embodiment, when the at least two mounting shells 110 are an integral structure, the side plates 112 located on the periphery can be connected as one unit, and the at least two mesh covers 170 are an integral structure, the cover frames 171 located on the periphery can be connected as one unit. In this case, the first fastener 113 can be installed only on the side plates 112 located on the periphery, and the second fastener 173 can be installed only on the cover frames 171 located on the periphery. Thus, by fastening only the first fastener 113 and the second fastener 173 on the periphery, the installation of multiple mounting shells 110 and multiple mesh covers 170 can be realized, simplifying the internal structure and the installation steps.

[0103] The present invention also proposes an indoor unit for an air conditioner, with reference to Figures 11 to 13The indoor unit of this air conditioner includes a housing 2000 and a radiation module 1000. The specific structure of the radiation module 1000 is as described in the above embodiments. Since this indoor unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The radiation module 1000 is connected to the housing 2000, and the opening 101 of the radiation module 1000 is arranged facing the outside of the housing 2000.

[0104] In this embodiment, the radiation module 1000 is connected to the housing 2000. It can be understood that the radiation module 1000 can be located inside or outside the housing 2000. The radiation module 1000 achieves its heating function by emitting infrared rays into the indoor air. Utilizing the fact that infrared rays are invisible light, it ensures that when the indoor unit of the air conditioner operates at night, it will not affect the user's sleep environment, thus improving user comfort.

[0105] When installed inside the housing 2000, the radiant module 1000 can be movably connected to the housing 2000. When the indoor unit of the air conditioner is in heating mode, the radiant module 1000 moves out from inside the housing 2000 to emit infrared rays to the indoor environment to quickly heat the indoor environment. When not in operation, the radiant module 1000 can be stored inside the housing 2000 without affecting the integrity of the overall appearance of the unit.

[0106] When installed outside the housing 2000, the radiant module 1000 can be fixedly connected to the housing 2000. The radiant module 1000 can be fixed in a certain position to radiate infrared rays to the front of the indoor unit of the air conditioner to heat the air in front and avoid indoor air temperature stratification. The radiant module 1000 can be movably connected relative to the housing 2000. When the indoor unit is heating, the radiant module 1000 can be adjusted to a preset position to heat the air in the required position. After heating for a certain period of time, the position of the radiant module 1000 can be adjusted again to heat the air in other positions, thereby further improving the uniformity of indoor air temperature distribution in the space.

[0107] In practical applications, the radiation module 1000 can be set on the top, side or bottom of the housing 2000. Its specific position is not limited here, as long as the radiation surface 141 of the radiation module 1000 faces the front of the housing 2000. It can be understood that the front includes the front, the side front, the lower front, the upper front, etc.

[0108] In one embodiment of the present invention, the mounting shell 110 is movably connected to the housing 2000; the mounting shell 110 can move relative to the housing 2000 to drive the radiation surface 141 of the radiation module 1000 to be arranged obliquely downward.

[0109] Understandably, since hot air is less dense than cold air, heated air tends to rise. By aligning the radiant surface 141 of the radiant module 1000 downwards, heat is radiated to the downward-facing air, preventing air stratification and enhancing air convection.

[0110] Optionally, the mounting housing 110 and the housing 2000 can be connected by a rotational connection or a sliding connection, and the specific connection method can be determined according to the installation position of the radiation module 1000.

[0111] When the radiant module 1000 is installed outside the housing 2000, the mounting shell 110 can be rotatably connected to the housing 2000. When not in operation, the radiant module 1000 can rotate toward the surface of the housing 2000 to adhere to the surface of the housing 2000, ensuring the overall appearance of the machine. When in operation, the radiant module 1000 can rotate relative to the housing 2000 so that the radiant surface 141 faces obliquely downward, ensuring rapid heating of indoor air and improving temperature stratification.

[0112] When the radiant module 1000 is installed inside the housing 2000, it is hidden inside the housing 2000 when not in operation, and extends outward from the housing 2000 to radiate heat when in operation. In this case, the mounting shell 110 can be slidably connected to the housing 2000, which occupies less space and improves the compactness of the overall structure compared to the rotating extension method.

[0113] In one embodiment of the present invention, the angle α at which the radiating surface 141 is tilted downward relative to the horizontal plane is defined to be not less than 15° and not greater than 75°.

[0114] In this embodiment, when the indoor unit of the air conditioner is suspended at a high altitude, the radiant module 1000 is normally turned on for radiant heating, and the radiant surface 141 forms a certain tilt angle α ∈ [15°, 75°] with the horizontal plane, so that the radiant surface 141 has a good effect on improving the temperature stratification of the air in the space. It is understood that the tilt angle α cannot be too large or too small. If it is too small, the radiant surface 141 is too far towards the ground, and its orientation may differ greatly from that of the air outlet of the indoor unit of the air conditioner, resulting in a large gap between the radiant area and the area affected by the air outlet, thus causing temperature stratification in the space. If it is too large, the radiant surface 141 is too far forward, and it cannot heat the low-temperature air in the middle and lower parts of the room, thus causing temperature stratification in the space. In this embodiment, considering the comfort of the indoor space, the downward tilt angle α of the radiant surface 141 relative to the horizontal plane can be selected as [30°, 60°], such as 30°, 35°, 40°, 45°, 50°, 55° or 60°, etc.

[0115] In one embodiment of the present invention, the housing 2000 is provided with an air inlet 201, an air outlet 202, and an air duct connecting the air inlet 201 and the air outlet 202;

[0116] The radiation module 1000 includes at least two connected mounting shells 110, with a ventilation hole 180 formed between two adjacent mounting shells 110. The radiation module 1000 is installed at the air inlet, and the ventilation hole 180 connects the air duct to the indoor environment.

[0117] Understandably, the casing 2000 of the indoor unit of the air conditioner serves to support and install the internal components. The casing 2000 has an air inlet 201, an air outlet 202, and an air duct connecting the air inlet 201 and the air outlet 202. The air duct contains a heat exchanger and a fan. The fan draws indoor air into the casing 100 through the air inlet 201, where it is heated by the heat exchanger, and then blown out of the casing 202 into the room, thus regulating the heat exchange of indoor air. In this embodiment, the radiant module 1000 is installed at the air inlet 201. The radiant module 1000 has ventilation holes 180 between two adjacent mounting shells 110. These ventilation holes 180 connect the ventilation duct to the indoor environment to ensure adequate air intake for the indoor unit. Simultaneously, the radiant module 1000 heats the incoming airflow to reduce the temperature difference between the incoming and outgoing air, thereby reducing the heating energy consumption of the indoor unit and improving energy efficiency.

[0118] The present invention also proposes an air conditioner, which includes an indoor unit. The specific structure of the indoor unit is as described in the above embodiments. Since the air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0119] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
