The following description will take an air conditioner as an example.

In the embodiment of the present invention, as shown in fig. 1 to 10, the indoor unit of an air conditioner includes a casing 100 and an infrared radiation module 200.

The casing 100 includes a bottom plate 110 and end caps 120 disposed at both sides of the bottom plate 110;

The specific internal structure of the air conditioner can refer to the structure of a conventional air conditioner hanging machine, and is not described herein. In this embodiment, the casing 100 includes a bottom plate 110 and end caps 120 disposed at two sides of the bottom plate 110, and the movable infrared radiation module 200 is disposed on the bottom plate 110 or the end caps 120, and the infrared radiation module 200 has a radiation surface 201, and the radiation surface 201 can radiate infrared rays outwards to heat indoor air. The infrared radiation module 200 can move relative to the base plate 110 or the end cover 120, so that the radiation surface 201 can adjust the radiation direction of the radiation surface 201 according to the working state of the indoor unit of the air conditioner, thereby realizing rapid heating of the air in the space where the casing 100 is located, and improving the heating efficiency of the indoor unit.

It is understood that, when the infrared radiation module 200 is movably installed on the bottom plate 110 of the chassis 100, the infrared radiation module 200 may rotate or slide with respect to the bottom plate 110, so that the radiation direction of the radiation surface 201 is adjusted according to the movement of the infrared radiation module 200. Alternatively, the radiation surface 201 may face the front side of the air conditioning indoor unit, and may be adjusted to face straight ahead, side-ahead, or lower-ahead, or the like. When the infrared radiation module 200 is movably mounted to the end cap 120, the infrared radiation module 200 may rotate or slide with respect to the end cap 120 such that the radiation direction of the radiation surface 201 is adjusted according to the movement of the infrared radiation module 200. Alternatively, the radiation surface 201 may be directed toward the front side of the air conditioning indoor unit, and the first direction may be adjusted to be a front-right direction, a side-front direction, or a lower-front direction, and so on.

In practical applications, the infrared radiation module 200 may be disposed inside the casing 100, or may be disposed outside the casing 100:

the infrared radiation module 200 may be installed inside the chassis 100, that is, may be accommodated inside the bottom plate 110 or inside the end cover 120. When the infrared radiation module 200 is installed inside the cabinet 100, a sliding connection or a rotating connection may be adopted, and in a non-operating state, the infrared radiation module 200 is received inside the cabinet 100, and in an operating state, the infrared radiation module 200 protrudes from the inside of the cabinet 100 in a sliding or rotating manner, so that the radiation surface 201 faces the outside of the cabinet 100 and emits infrared rays to the indoor environment to rapidly heat the temperature of the indoor environment.

The infrared radiation module 200 may be installed at the outside of the cabinet 100 while the infrared radiation module 200 is coupled to the side or the bottom of the cabinet 100, and when the operation of the infrared radiation module 200 is required, the infrared radiation module 200 may be rotatably moved with respect to the cabinet 100 such that the radiation surface 201 faces the front side of the cabinet 100 and radiates infrared rays to the air of the front side to rapidly heat the ambient temperature. It can be understood that, in the operating state, the infrared radiation module 200 may be fixed to a certain fixed position to operate, or may be adjusted between different operating positions, for example, when the indoor unit is in heating operation, the infrared radiation module 200 may be adjusted to a preset position to heat air at a desired position, and after heating for a certain time, the position of the infrared radiation module 200 may be adjusted again to heat air at other positions, so as to further improve the uniformity of the temperature distribution of the indoor air in the space.

It should be noted that the operating state of the infrared radiation module 200 is determined by the operating state of the indoor unit of the air conditioner, for example, when the indoor unit of the air conditioner operates to heat, the heating effect can be accelerated by turning on the infrared radiation module 200, and the indoor space temperature stratification phenomenon can be improved by adjusting the radiation direction of the infrared radiation module 200. In cold winter, after the air conditioner operates in the heating mode for a period of time, frost may form on the outdoor unit, at this time, the air conditioner may be adjusted to the cooling mode or stop the heating mode, cold air may be blown out from the indoor unit of the air conditioner to fluctuate the indoor temperature, and at this time, the infrared radiation module 200 is turned on to avoid temperature fluctuation caused by the defrosting mode, so that the use comfort of a user is improved.

In the air-conditioning indoor unit in the technical scheme of the utility model, the movable infrared radiation module 200 is arranged on the bottom plate 110 or the end cover 120 of the casing 100, and the infrared radiation module 200 is provided with the radiation surface 201 which radiates infrared rays towards the outside, so that the infrared radiation module 200 can move relative to the bottom plate 110 or the end cover 120 to adjust the radiation direction of the radiation surface 201 towards the outside of the air-conditioning indoor unit, thereby realizing the rapid heating of indoor air, improving the temperature stratification phenomenon of an indoor space and achieving the purpose of improving the comfort level of the indoor air.

In an embodiment of the present invention, referring to fig. 1 to 10, the infrared radiation module 200 is disposed outside the casing 100 and rotatably connected to the casing 100.

In the present embodiment, the infrared radiation module 200 is rotatably connected to the outside of the cabinet 100, and it can be understood that the infrared radiation module 200 can rotate up and down with respect to the top and bottom of the cabinet 100, or rotate left and right with respect to the side of the cabinet 100.

It can be understood that the infrared radiation module 200 is disposed outside the casing 100, and does not occupy the space inside the casing 100, and does not affect the installation position and form of the indoor unit body of the air conditioner, so that the original refrigeration cycle or heating cycle of the indoor unit of the air conditioner is not affected.

In an embodiment of the present invention, referring to fig. 1 to 10, the infrared radiation module 200 has a storage state and an extended state:

in the storage state, the infrared radiation module 200 is attached to the outer surface of the case 100;

in the extended state, the infrared radiation module 200 is rotated in a direction away from the cabinet 100 so that the radiation surface 201 faces the front side of the cabinet 100.

In this embodiment, the infrared radiation module 200 can be rotationally moved between the housed state and the extended state with respect to the chassis 100. In the storage state, the infrared radiation module 200 does not work, and moves to be attached to the outer surface of the casing 100, so that the compactness of the appearance of the whole machine is ensured, the exposed area is reduced, and the dust adhesion is reduced. In the extended state, the infrared radiation module 200 is turned on, the radiation surface 201 radiates heat to the outside, and at this time, the infrared radiation module 200 is turned to a direction away from the outer surface of the cabinet 100, so that the radiation surface 201 faces the front side of the cabinet 100, thereby realizing rapid radiation heating of the air in the space region of the front side of the cabinet 100.

It is understood that in the extended state, the infrared radiation module 200 may be fixed to a fixed position for operation, or may be rotated and adjusted within a certain area to further extend the range of radiation heat of the radiation surface 201.

In one embodiment, referring to fig. 7 to 10, the infrared radiation module 200 is disposed at the bottom of the chassis 100; in the extended state, the infrared radiation module 200 may be turned upside down with respect to the bottom plate 110 of the cabinet 100 such that the radiation surface 201 is disposed obliquely downward.

In this embodiment, the infrared radiation module 200 is rotatably connected to the bottom plate 110 of the casing 100, and can be turned upside down relative to the bottom plate 110, so as to adjust the radiation direction of the radiation surface 201.

It can be understood that the air conditioner hanging machine is usually installed at a higher position, and the air outlet of the cabinet 100 is also at a higher position in the indoor space, and when hot air is blown out to the indoor space, the indoor air temperature may be layered, in this embodiment, the infrared radiation module 200 is disposed at the bottom of the cabinet 100, and can be turned over relative to the bottom plate 110, so that the radiation surface 201 radiates heat towards the oblique lower side, so as to heat the air at the oblique lower side, and achieve the effect of improving the air layering.

It should be noted that, in the extended state, the infrared radiation module 200 may rotate to a fixed position to radiate heat in a fixed direction, or may rotate in a certain area, so that the radiation surface 201 can radiate heat to different areas.

Alternatively, on the basis of the foregoing embodiment, when the infrared radiation module 200 is not required to operate, the infrared radiation module 200 may be turned toward the base plate 110 to be attached to the outer surface of the base plate 110, thereby ensuring the integrity of the appearance of the whole device.

In an embodiment, the bottom plate 110 has a receiving cavity (not shown), and the infrared radiation module 200 is received in the receiving cavity in the receiving state. In this embodiment, when the infrared radiation module 200 is not opened, it is accommodated in the casing 100, so that the appearance is not affected, and the heating effect is further prevented from being affected by dust and dirt.

In some embodiments, referring to fig. 1 to 6, the infrared radiation module 200 is provided at a side of the cabinet 100; in an operating state, the infrared radiation module 200 may be flipped left and right with respect to the end cap 120 of the cabinet 100.

In this embodiment, the infrared radiation module 200 is rotatably connected to the end cover 120 of the casing 100, and can be turned left and right relative to the end cover 120, so as to adjust the orientation of the radiation surface 201.

Optionally, in the stowed state, the radiating surface 201 is disposed away from the end cap 120; in the extended state, the infrared radiation module 200 may be rotated outward with respect to the end cover 120 to open the radiation surface 201 toward the front side of the cabinet 100. It is understood that the infrared radiation module 200 is rotated toward the end cap 120 to be attached to the outer surface of the end cap 120 when the infrared radiation module 200 is not in operation. When the infrared radiation module 200 is operated, the infrared radiation module 200 can rotate relative to the end cover 120 in a direction away from the end cover 120, so that the radiation surface 201 faces the front side of the cabinet 100, and the air in the space of the front side area of the cabinet 100 can be heated by radiation.

It should be noted that the above embodiment may be applied to the case that the radiation surface 201 of the infrared radiation module 200 faces outward, and at this time, the rotation driving mechanism may drive the infrared radiation module 200 to rotate in the direction away from the end cover 120, so that the radiation surface 201 radiates heat toward the outside of the casing 100.

In practical application process, also can be when accomodating the state, set up infrared radiation module 200's radiant surface 201 towards end cover 120, so when infrared radiation module 200 was out of work, its radiant surface 201 was hidden to avoid radiant surface 201 to expose outside and the ash that falls leads to dirty stifled influence heat radiation effect.

Based on the above-mentioned infrared radiation module 200 is on the basis that the radiation surface 201 faces the end cover 120 when the state is accomodate, when the infrared radiation module 200 needs to work, the radiation surface 201 can be turned over once or many times to face the outside of the cabinet 100:

alternatively, the infrared radiation module 200 is coupled to the rear end of the cover 120, and in the extended state, the infrared radiation module 200 may be rotated outward with respect to the cover 120 to open such that the radiation surface 201 faces the front side of the cabinet 100. In this embodiment, the rotation central axis of the infrared radiation module 200 is located at the rear end of the end cap 120, and at this time, the radiation surface 201 can be exposed only by opening the infrared radiation module 200 to rotate outward relative to the end cap 120, so as to realize the function of radiating heat outward. In this embodiment, a gear transmission mechanism or a rotation mechanism such as a rotation motor may be used to realize the relative rotation between the infrared radiation module 200 and the end cap 120.

Alternatively, the infrared radiation module 200 is coupled to the front end of the cover 120, and in the extended state, the infrared radiation module 200 is opened by being rotated outward with respect to the cover 120 and can be turned upside down so that the radiation surface 201 faces the front side of the cabinet 100. In this embodiment, the infrared radiation module 200 may be turned left and right and turned up and down with respect to the end cover 120, and when the infrared radiation module 200 is applied, the infrared radiation module 200 may be turned outward with respect to the end cover 120 to move the radiation surface 201 from the direction facing the end cover 120 to the back side (wall or mounting surface, etc.) of the casing 100, and then turned up and down to move the radiation surface 201 from the direction facing the back side to the front side of the casing 100, so as to achieve the purpose of radiating heat into the indoor space. In this embodiment, a rotation driving mechanism may be used to drive the ir radiation module 200 to rotate outward relative to the end cap 120 so that the radiation surface 201 faces the back side of the casing 100, and then another rotation driving mechanism may be used to drive the ir radiation module 200 to turn up and down so as to move the radiation surface 201 to face the front side of the casing 100.

In an embodiment of the present invention, referring to fig. 1 to 10, the infrared radiation module 200 is rotated outward by an angle of not more than 100 ° with respect to the outer surface of the set cover 100.

It is understood that, in the accommodated state, the angle between the infrared radiation module 200 and the outer surface of the set cover 100 is 0 °; in the extended state, the infrared radiation module 200 may be rotated outward relative to the outer surface of the housing 100 to a predetermined position within the range of the angle α, and may be arbitrarily adjusted within α to achieve that the radiation surface 201 can be fixed at a certain position within [0 °, 100 ° ] to radiate heat indoors, or the radiation position can be arbitrarily adjusted within [0 °, 100 ° ] to expand the heat radiation range.

Alternatively, the rotation angle of the infrared radiation module 200 with respect to the outer surface of the chassis 100 cannot be too large, which easily causes the radiation surface 201 to move too far toward the upper or rear surface of the chassis 100, and the heat radiation effect is poor.

In order to improve the heat radiation effect, in an embodiment of the present invention, referring to fig. 11 to 13, the radiation surface 201 is a plane or a convex arc surface protruding outward.

It can be understood that when the radiation surface 201 is a plane, the heating function of a desired position can be realized by adjusting the orientation of the radiation surface 201 in the infrared radiation module 200, for example, when the indoor unit of the air conditioner is located at a high position, the radiation surface 201 can be adjusted to radiate heat towards the lower side or the front lower side.

When the radiation surface 201 is a convex arc surface, compared with a plane, the radiation range is expanded, so that the effect of a larger heat radiation range can be achieved only by adjusting the infrared radiation module 200 in a small range.

It can be understood that the radiation panel assembly may only include one radiation panel 230, the radiation panel 230 may be disposed on one side of the heating body 220 away from the back plate 210, and a distance is provided between the radiation panel 230 and the heating body 220, so that heat emitted by the heating body 220 may be radiated through the radiation panel 230, and thus the heat emitted by the heating body 220 may be radiated more uniformly through the radiation panel 230, and the radiation panel 230 may also have a protection effect on the heating body 220, thereby preventing the heating body 220 from falling down through the mesh enclosure 220.

In the practical application process, the heating body 220 is arranged in the back plate 210, the infrared rays radiated by the heating body 220 are realized in a mode of radiating around the heating body 220 as the center, the radiation panel 230 is arranged on the back plate 210, the radiation panel 230 can absorb the heat in the back plate 210 and radiate the infrared rays to the outside of the back plate 210 through the radiation surface 201, and compared with the heating body 220, the radiation center area of the infrared rays is increased. Meanwhile, the radiation panel 230 can conduct temperature inside the back plate 210 after absorbing infrared rays inside the back plate to uniform temperature, so that the temperature distribution on the radiation surface 201 is uniform, and further, the effect of uniformly radiating heat outwards from the radiation surface 201 is achieved.

The radiation panel 230 can soften the infrared ray of the heat generating body 220 in addition to uniformly controlling the temperature. In addition, the radiation panel 230 can prevent mosquitoes from entering the back plate 210, and meanwhile, the risk that the heating body 220 is damaged and falls off when the infrared radiation module 200 is installed at a high place can be avoided.

Or the radiation plate assembly may include only the reflective layer 240, and the reflective layer 240 is disposed on a side of the back plate 210 facing the heat generating body 220, so that heat radiated from the heat generating body 220 can be radiated to the room by reflection of the reflective layer 240.

In practical application, the reflective layer 240 may be directly attached to the inner wall of the back plate 210, or may be spaced from the back plate 210, or the back plate 210 and the reflective layer 240 are integrated, and the back plate 210 has a reflective function. To ensure good reflection, the reflective layer 240 may be a smooth metal such as stainless steel, aluminum, silver, copper, etc., or may be a polyester, polyimide film, etc., with a metal-plated mounting surface.

Alternatively, the radiation plate assembly may include both the radiation plate 230 and the reflective layer 240. The position of the reflective layer 240 may be determined according to actual conditions, and it may be only disposed on the side of the heat generating body 220 facing away from the radiation panel 230 to directly reflect the infrared rays to the radiation panel 230; alternatively, the reflective layer 240 may cover the whole area of the back plate 210 to receive all the infrared rays except the radiation panel 230, and emit the infrared rays to the radiation panel 230 after a single reflection on one surface or multiple reflections on multiple surfaces, so as to improve the utilization rate of the infrared rays and prevent the infrared rays from directly acting on the back plate 210.

In this embodiment, in order to have a better radiation effect, the radiation plate assembly includes a reflective layer 240 and a radiation panel 230; the reflective layer 240 is disposed on one side of the back plate 210 facing the heat generating body 220 and spaced from the heat generating body 220; the radiation panel 230 is disposed on a side of the heat generating body 220 away from the back plate 210, and is spaced from the heat generating body 220, the radiation panel 230 is disposed in the installation cavity, and a surface of the radiation panel 230 away from the heat generating body 220 is a radiation surface 201.

By simultaneously coupling the radiation panel 230 and the reflective layer 240; the reflective layer 240 is disposed on a side of the back plate 210 facing the heat generating body 220, and the reflective layer 240 is used for reflecting heat radiated by the heat generating body 220, so as to prevent the back plate 210 from reflecting most of the heat into the room through the reflective layer 240, thereby increasing the radiation amount radiated into the room. In addition, by disposing the radiation panel 230 on the side of the heat generating body 220 away from the back plate 210, the heat reflected by the reflective layer 240 can be uniformly radiated to the room through the radiation panel 230. Specifically, the reflective layer 240 may be coated on the inner surface of the back plate 210, or may be spaced apart from the back plate 210. For ease of installation and compactness, an optional reflective layer 240 is applied to the inner surface of the back-plate 210.

Of course, in other embodiments, the coating having a reflective effect may also be applied in other components. For example, the heat generating body 220 may be coated with a reflective coating 250 on the side facing the back-plate 210. The surface shape of the reflective coating 250 may be adapted to the shape of the side of the heat generating body 220 facing the back plate 210.

Alternatively, silver may be plated on the surface of the heat generating body 220 to enhance the radiation directivity toward the radiation panel 230, and at the same time, the temperature of the back plate 210 can be lowered to ensure the structural stability.

In an embodiment of the utility model, referring to fig. 11 to 13, the infrared radiation module 200 further includes an insulating layer 270, and the insulating layer 270 is sandwiched between the back plate 210 and the reflective layer 240.

By interposing the insulating layer 270 between the reflective layer 240 and the back plate 210, the insulating layer 270 may insulate a portion of heat passing through the reflective layer 240, thereby preventing the back plate 210 and the housing 100 proximate to the back plate 210 from being damaged by high-temperature heat.

The reflective layer 240 may function to lower the heat transfer temperature of the insulation layer 270 in addition to reflecting infrared rays.

In practical application, the heat insulating layer 270 is made of heat insulating material, and the heat insulating material is preferably foam plastic (polyurethane (PUR), Polystyrene (PS), polyvinyl chloride (PVC), Polyethylene (PE), phenolic resin (PF), etc.).
