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, a rotatable infrared radiation module 200 is disposed on the casing 100, the infrared radiation module 200 has a radiation surface 201 capable of radiating infrared rays outwards, and the infrared radiation module 200 can be turned over relative to the casing 100, so that the radiation surface 201 can be disposed in an exposed state towards the outside of the casing 100, thereby achieving a function of radiating heat outwards; the radiation surface 201 can be hidden towards the inside of the casing 100, so that the exposed area of the radiation surface 201 is reduced, and the dustproof effect is achieved. It can be understood that when the radiation surface 201 is hidden in the casing 100, the radiation surface 201 is not visible from the appearance of the casing 100, so that the radiation surface 201 is prevented from being dirty and blocked due to dust falling.

It is understood that the infrared radiation module 200 has an operating state and a non-operating state, and can be switched between the operating state and the non-operating state, in the operating state, the radiation surface 201 is in the exposed state, and in the non-operating state, the radiation surface 201 is in the hidden state.

In practical applications, the infrared radiation module 200 may be disposed on the top, side, front, bottom, or the like of the chassis 100. The infrared radiation module 200 may be disposed inside the cabinet 100 or outside the cabinet 100:

when installed outside the cabinet 100, the radiation surface 201 may be turned over to face the outside of the cabinet 100 to radiate infrared rays to the space outside the cabinet 100 for rapid heating; also through the mode of upset for radiant surface 201 sets up towards the surface of casing 100, so that radiant surface 201 closes on casing 100 surface or attached in the surface of casing 100, realizes radiant surface 201's the purpose of hiding, and then has avoided radiant surface 201 to fall grey filth and has blockked up the condition emergence that influences the heating effect.

When installed inside the casing 100, the radiation surface 201 may be received inside the casing 100 or exposed from the surface of the casing 100 by turning.

In this manner, the chassis 100 may be provided with the opening 101 or the escape groove at a position corresponding to the infrared radiation module 200.

It can be understood that, considering that the indoor unit of the air conditioner is installed at a higher position in the space, in order to ensure a better heat radiation effect to the indoor air, the infrared radiation module 200 can be arranged at the side, front or bottom of the casing 100, and the orientation of the radiation surface 201 is arranged from the surface of the casing 100 to the outside, so as to increase the space of heat radiation, achieve the purpose of improving the indoor air temperature stratification, and further improve the indoor air comfort level.

It can be understood that the working state of the infrared radiation module 200 is determined by the working state of the indoor unit of the air conditioner, for example, when the indoor unit of the air conditioner is operated to heat, the infrared radiation module 200 is turned over to enable the radiation surface 201 to radiate heat outwards, so that the heating effect can be accelerated, and the phenomenon of temperature stratification of the indoor space can be improved. When the air conditioner runs in the heating mode in cold winter for a period of time, frost may form on the outdoor unit, at this time, the air conditioner may be adjusted to be in the cooling mode or stop the heating mode, the indoor unit of the air conditioner may blow out cold air to fluctuate the indoor temperature, and at this time, the infrared radiation module 200 is turned over to enable the radiation surface 201 to radiate heat towards the outside, so that temperature fluctuation caused by the defrosting mode is avoided, and the use comfort of a user is improved.

In the air-conditioning indoor unit adopting the technical scheme, the turnover infrared radiation module 200 is arranged on the casing 100, the infrared radiation module 200 is provided with the radiation surface 201 capable of radiating infrared rays outwards, and the infrared radiation module 200 can turn over relative to the casing 100 so that the radiation surface 201 has an exposed state facing the outside of the casing 100 and a hidden state facing the inside of the casing 100, so that when the air-conditioning indoor unit needs the infrared radiation module 200 to work, the radiation surface 201 is in the exposed state and radiates heat towards the space outside, and the purpose of quickly heating air is achieved; meanwhile, the embodiment can also turn over the radiation surface 201 to be in a hidden state when the infrared radiation module 200 is not needed to work, so that a dustproof effect is achieved, the radiation surface 201 is prevented from being dusty and blocked to influence a heating effect, and the purpose of improving the heating efficiency is achieved.

In an embodiment of the present invention, referring to fig. 1 to 5, the chassis 100 includes a panel 110, and the infrared radiation module 200 is rotatably connected to the panel 110 such that the radiation surface 201 is disposed toward an inner side of the panel 110 or toward an outer side of the panel 110.

It is understood that the panel 110 is located at the front position of the casing 100, and the infrared radiation module 200 is rotatably connected to the panel 110, and optionally, the infrared radiation module 200 may be turned in a left-right direction or a front-back direction with respect to the panel 110 to enable the radiation surface 201 to be hidden toward the inside of the panel 110 or exposed toward the outside of the panel 110.

In the practical application process, the indoor unit of the air conditioner is installed at a higher position, the infrared radiation module 200 is rotatably connected to the panel 110, when the radiation surface 201 is exposed, the radiation surface is also at a relatively higher position, at the moment, the radiation surface 201 can radiate infrared rays towards the front side space of the panel 110, optionally, the front side comprises a front side, a side front side or a lower front side and the like, the range of the front side space covered by the air outlet airflow of the indoor unit of the air conditioner is larger, the phenomenon of spatial temperature stratification caused by the limitation of the air outlet airflow direction can be improved, and the uniformity of the temperature distribution of indoor air in the space is improved.

In an embodiment of the utility model, referring to fig. 1 to 5, the panel 110 is provided with an opening 101, and the infrared radiation module 200 can be turned over relative to the panel 110, so that the radiation surface 201 is hidden inside the panel 110 or exposed in the opening 101.

In this embodiment, consider that the air conditioning indoor set is installed in the higher position in space, and the position of opening 101 is the outside thermal channel of radiation of infrared radiation module 200, for guaranteeing the better heat radiation effect to the room air, panel 110 can be located to this opening 101, and the orientation of radiation face 201 is towards outside setting for from casing 100 surface simultaneously to the space of increase heat radiation, reach the purpose that improves the layering of room air temperature, and then promote the room air comfort level.

Alternatively, the panel 110 may be a vertical plate or an inclined plate, and when the panel 110 is the vertical plate, the opening 101 may be opened toward the right front of the cabinet 100, and when the panel 110 is the inclined plate, the opening 101 may be opened toward a direction in which the panel 110 is inclined. The radiation surface 201 of the infrared radiation module 200 may be in line with or not in line with the plate surface direction of the panel 110.

It can be understood that the inclination angle cannot be too large or too small, and if the inclination angle is too small, the radiation surface 201 faces the ground too much, which may be greatly different from the orientation of the air outlet of the indoor unit of the air conditioner, so that the interval area between the radiation area and the action area of the air outlet is large, and the spatial temperature stratification is caused; if the size is too large, the radiation surface 201 is too directed to the front, and the low-temperature air in the middle and lower part of the room is not heated, resulting in spatial temperature stratification. In the present embodiment, in consideration of comfort of the indoor space, the angle at which the radiation surface 201 is inclined downward with respect to the horizontal plane may be selected to be [30 °,60 °, such as 30 °, 35 °, 40 °, 45 °, 50 °, 55 °, or 60 °, etc.

It can be understood that the back surface 202 and the radiation surface 201 are two surfaces opposite to the infrared radiation module 200, and the radiation surface 201 and the back surface 202 are switched at the opening 101 by the turning motion of the infrared radiation module 200.

The driving mechanism 300 may be connected to a side, upper, lower, or middle portion of the panel 110. Alternatively, the driving mechanism 300 may be implemented by a transmission structure such as a motor-shaft sleeve.

In an embodiment of the present invention, the inner sidewall of the accommodating case 120 is configured as an arc surface. In this embodiment, the inner side wall of the housing case 120 is configured as an arc surface adapted to the rotation path of the infrared radiation module 200, so that the occupied space is reduced while the reliability of the rotation of the infrared radiation module 200 is ensured, and the compactness of the structural layout is improved.

In an embodiment of the present invention, referring to fig. 6 to 8, the infrared radiation module 200 includes a back plate 210, a mesh cap 260, and an infrared radiation element; the back plate 210 is mounted to the bottom plate 110 or the end cap 120 of the chassis 100; the mesh cap 260 covers the back plate 210 and forms an installation cavity together with the back plate 210; the installation intracavity is located to infrared heat radiation subassembly, and infrared heat radiation subassembly has radiating surface 201.

The infrared heat radiation member has a radiation surface 201 so that the radiation surface 201 can radiate heat indoors.

In an embodiment of the present invention, the infrared heat radiation assembly includes a heat generating body 220 and a radiation plate assembly; the heating body 220 is arranged in the mounting cavity, and a distance is arranged between the heating body and the back plate 210; the radiation plate assembly is arranged in the mounting cavity and is arranged at an interval with the heating body 220, and the radiation plate assembly is provided with a radiation surface 201.

It can be understood that the heating body 220 is a far infrared heating body, which can be silicon carbide, a metal tube, a quartz tube, carbon fiber, graphene, etc., and the basic composition can be a layer of high temperature resistant quartz glass coated on the carbon fiber, the middle of the glass is evacuated to form vacuum with a certain negative pressure, and damping springs are arranged at the two ends of the carbon fiber. The wavelength range of the far infrared rays is 1.5 microns-micron, the far infrared rays are invisible light, and when the far infrared rays are applied, particularly used at night or in a dark space, the eyes of a user cannot be affected, so that the safety of the user is ensured.

It is understood that the infrared radiation module 200 heats the surrounding environment by emitting infrared rays.

In an embodiment of the present invention, referring to fig. 6 to 8, 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.

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.

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 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. 6 to 8, 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.).
