The utility model provides an indoor unit of an air conditioner.

In the embodiment of the present invention, please refer to fig. 1 to 4 in combination, the indoor unit of an air conditioner includes a casing 100 and an infrared radiation module 200; the infrared radiation module 200 can be movably coupled to the housing 100 to adjust a radiation direction of the infrared radiation module 200.

By movably coupling the infrared radiation module 200 to the case 100, the radiation angle of the infrared radiation module 200 can be adjusted, so that it is possible to ensure heat radiation in all directions in the cabinet. Specifically, the infrared radiation module 200 may be rotatably coupled to the housing 100, and may be slidably coupled to the housing 100. When the infrared radiation module 200 is rotatably connected to the housing 100, the infrared radiation module 200 can be rotatably connected to the housing 100 through a rotating shaft, and the rotating shaft can be disposed on the infrared radiation module 200 or the housing 100. It will be appreciated that there may be one, two or three shafts etc. When only one rotating shaft is provided, the infrared radiation module 200 can only rotate in one plane when rotating through the rotating shaft; when the number of the rotating shafts is two, the two rotating shafts can be vertically arranged, the infrared radiation module 200 can be selected to rotate through any one rotating shaft, and when the infrared radiation module 200 rotates through different rotating shafts, the rotating planes where the infrared radiation module 200 is located are different, so that the rotating range of the infrared radiation module 200 is enlarged, and the effect of enlarging the radiation angle and the radiation range is further realized. Or, the infrared radiation module 200 may also be rotatably connected to the housing 100 through a universal joint, and at this time, on the premise that the housing 100 does not interfere with the infrared radiation module 200, the infrared radiation module 200 may rotate in any direction, thereby implementing a larger radiation angle and range. The infrared radiation module 200 may be slidably coupled to the housing 100, and may slide along a surface of the housing 100 or may slide toward or away from a surface of the housing 100 when the infrared radiation module 200 slides relative to the housing 100. When the infrared radiation module 200 slides relative to the housing 100, one of the two can be provided with a sliding groove, and the other one is provided with a sliding block clamped into the sliding groove, so that the sliding effect of the infrared radiation module 200 relative to the housing 100 is realized through the sliding effect of the sliding block in the sliding groove, and the effect of expanding or changing the radiation direction can also be realized through the arrangement.

In addition, it can be understood that, when the infrared radiation module 200 is movably connected to the housing 100, the infrared radiation module 200 can be disposed on the front side, the left side, and the right side of the housing 100, and at this time, the infrared radiation module 200 can avoid shielding the air inlet and the air outlet of the housing 100. Of course, when the top of the housing 100 is provided with an air inlet, the infrared radiation module 200 may also be disposed on the top of the housing 100 and block a portion of the air inlet, so as to ensure that another portion of the air inlet is used for air inlet. Or the infrared radiation module 200 is disposed on the top of the housing 100 and blocks all the air inlets, and the infrared radiation module 200 itself has a vent hole, which is communicated with the air channel in the inner cavity of the housing 100. Or, the infrared radiation module 200 may also be disposed at the bottom of the housing 100, and when the front end of the bottom of the housing 100 is provided with the air outlet, the infrared radiation module 200 may avoid the air outlet and may also shield part of the air outlet; or the infrared radiation module 200 can also completely shield the air outlet, and the infrared radiation module 200 itself has a vent hole, which is communicated with the air channel of the inner cavity of the housing 100.

When the air-conditioning indoor unit is installed, one side of the casing 100 is used to be attached to an installation surface (for example, a wall surface or a partition surface), and with reference to a state of the air-conditioning indoor unit when installed, a direction in which the air-conditioning indoor unit is away from the installation surface is a front direction, a direction in which the air-conditioning indoor unit faces the installation surface is a rear direction, a direction from the floor surface to the ceiling surface is an upper direction, and a direction from the ceiling surface to the floor surface is a lower direction. When the user is right opposite to the front side of the indoor unit of the air conditioner, the left-hand direction of the user is the left side, and the right-hand direction of the user is the right side.

In addition, in the technical scheme of the utility model, by arranging the infrared radiation module 200, compared with a common heat radiation module, the infrared radiation module 200 has the advantages that the infrared rays emitted by the infrared radiation module 200 cannot be seen by the eyes of the user, and further, when the infrared radiation module 200 is turned on at night, the influence of the light emitted by the infrared radiation module 200 on the sleep quality of the user is avoided. Of course, the present invention is not limited to providing only the infrared radiation module 200 at the housing 100, and a general heat radiation module may be provided at the housing 100 in other embodiments. A general heat radiation module refers to a radiation module that directly radiates heat outward instead of emitting infrared rays after the radiation module itself is heated.

According to the technical scheme of the utility model, the infrared radiation module 200 is movably connected to the shell 100, so that a user can flexibly adjust the radiation direction of the infrared radiation module 200, and the infrared radiation module 200 has a better radiation effect.

Further, the housing 100 has a front panel 110; the infrared radiation module 200 is rotatably coupled to the front panel 110 and serves to perform infrared heat radiation indoors.

It can be understood that the infrared radiation module 200 has at least one radiation surface, and when the infrared radiation module 200 rotates relative to the front panel 110, the radiation surface also rotates relative to the front panel 110, so that the radiation direction of the infrared radiation module 200 can be adjusted by rotating and connecting the infrared radiation module 200 to the front panel 110, and further the radiation angle of the infrared radiation module 200 can be flexibly adjusted, thereby ensuring that heat radiation is performed in all directions indoors.

In order to achieve the effect that the infrared radiation module 200 is rotatably coupled to the front panel 110, a rotation shaft may be provided on the front panel 110, and the infrared radiation module 200 is hinged to the rotation shaft. Or the infrared radiation module 200 is provided with a rotating shaft, the front panel 110 is correspondingly provided with a shaft hole, and the infrared radiation module 200 is installed in the shaft hole through the rotating shaft, so that the effect that the infrared radiation module 200 can rotate relative to the front panel 110 is realized.

Specifically, the infrared radiation module 200 may rotate in the front-rear direction or may swing in the left-right direction when rotating with respect to the front panel 110. In addition, when the infrared radiation module 200 is rotatably connected to the front panel 110, the infrared radiation module 200 may be rotatably connected to the front panel 110 through a rotation shaft, and at this time, the infrared radiation module 200 may rotate in a certain plane. When the infrared radiation module 200 is rotatably connected to the front panel 110, the infrared radiation module 200 may also be rotatably connected to the front panel 110 through a universal joint, and at this time, the infrared radiation module 200 may rotate in any direction. For example, the rotation may be in the left-right direction or in the front-back direction. Specifically, the front panel 110 may be connected with the universal joint, and the infrared radiation module 200 has a connecting portion connected with the universal joint in a matching manner, so that the infrared radiation module 200 is matched with the universal joint through the connecting portion, thereby achieving an effect that the infrared radiation module 200 can rotate in any direction relative to the front panel 110.

According to the technical scheme of the utility model, the infrared radiation module 200 is rotatably connected to the front panel 110, so that the angle of the infrared radiation module 200 can be flexibly adjusted when a user uses the air conditioner indoor unit. When heat radiation is required, the infrared radiation module 200 can be adjusted to a preferred angle to achieve a better radiation effect.

In this embodiment, referring to fig. 1 to 4, the housing 100 further includes a chassis 120 and a face frame 130, the face frame 130 covers the chassis 120 and forms an accommodating cavity together with the chassis 120, an air inlet is disposed at the top of the face frame 130, an air outlet is disposed at the front lower portion of the face frame 130, the air outlet is communicated with the air inlet, the front panel 110 is mounted on the face frame 130 and located above the air outlet, and the front panel 110 is disposed at the front side of the face frame 130.

The base plate 120 and the face frame 130 are covered to form an accommodating cavity, so that components such as a heat exchanger and a wind wheel of the indoor unit of the air conditioner can be installed in the accommodating cavity. In order to realize the effect of the air inlet and outlet of the air-conditioning indoor unit, the air outlet can be arranged below the front of the face frame 130, and the top of the face frame 130 can be provided with an air inlet grille, so that indoor air enters air from the air inlet grille, is blown to the air outlet under the action of the wind wheel after the heat exchanger in the accommodating cavity, and further realizes the air supply effect through the air outlet. In addition, by mounting the front panel 110 on the front side of the face frame 130, the components in the housing chamber can be shielded, and the components in the housing chamber can be protected.

Of course, in other embodiments, the positions of the air inlet and the air outlet of the indoor unit of the air conditioner may be different from those of the above-described embodiments. For example, in an embodiment, an air inlet of the indoor unit of the air conditioner may be opened on the front panel 110, and the infrared radiation module 200 may be rotatably disposed at the air inlet of the front panel 110, or may be rotatably disposed at a position where the front panel 110 is away from the air inlet. It can be understood that, when the infrared radiation module 200 is rotatably disposed at the air inlet of the front panel 110, the infrared radiation module 200 can be rotated to avoid and open the air inlet, so that the indoor air can enter the air conditioner indoor unit from the air inlet to exchange heat. When the air conditioner indoor unit does not need to be opened, the infrared radiation module 200 can be rotated to a state of shielding the air inlet in advance, and then more sundries or dust falling into the accommodating cavity is avoided.

Further, the air conditioning indoor unit further includes a driving device 300, and the driving device 300 is disposed on the casing 100 and is drivingly connected to the infrared radiation module 200 to drive the infrared radiation module 200 to rotate.

The driving device 300 is arranged on the casing 100, so that the driving device 300 can be connected with the casing 100; the driving device 300 is used for driving and connecting the infrared radiation module 200, so that the effect of driving the infrared radiation module 200 to rotate through the driving device 300 can be realized, and the infrared radiation module 200 is prevented from being rotated manually.

When the driving device 300 is provided in the housing 100, the driving device 300 may be attached to the front panel 110 of the housing 100, or may be connected to another part of the housing 100, as long as the driving device 300 can drive the infrared radiation module 200 to rotate without being affected by other parts. The driving device 300 may be installed inside the casing 100, or may be installed on an outer surface of the casing 100. The driving device 300 is connected to the infrared radiation module 200 in a driving manner, and the driving device 300 may include a link assembly, or the driving device 300 may include a gear assembly, or the driving device 300 may include a cam-link mechanism, etc. For example, when the driving device 300 is a connecting rod transmission assembly, the connecting rod assembly includes a crank, a first connecting rod and a second connecting rod, one end of the crank is rotatably connected to the housing 100, one end of the first connecting rod is rotatably connected to the other end of the crank, the other end of the first connecting rod is rotatably connected to one end of the second connecting rod, and the other end of the second connecting rod is rotatably connected to the infrared radiation module 200; when the crank rotates, the crank drives the first connecting rod to rotate, and then the first connecting rod drives the second connecting rod to rotate, and finally the second connecting rod drives the infrared radiation module 200 to rotate. Of course, the crank can also be connected with a motor in a transmission way, and then the motor drives the crank to rotate; or the motor shaft of the motor can be used as the crank. When drive arrangement 300 is the gear drive subassembly, the gear assembly includes driving gear and driven gear, and driving gear and driven gear meshing, the driving gear can be by motor drive, and the driven gear cover is located infrared radiation module 200's pivot and is driven the pivot and rotate to the driving gear drives driven gear and rotates, and then driven gear drives the pivot and rotates, finally realizes infrared radiation module 200 along with pivot pivoted effect. Of course, when the driving device 300 includes a gear assembly, the manner of driving the infrared radiation module 200 to rotate is limited to this, as long as the gear assembly can drive the infrared radiation module 200 to rotate.

Specifically, referring to fig. 1 to 4, in the present embodiment, the infrared radiation module 200 has a top end and a bottom end opposite to each other, the bottom end of the infrared radiation module 200 is rotatably connected to the front panel 110, and the driving device 300 is connected to the top end of the infrared radiation module 200 in a driving manner.

The bottom end of the infrared radiation module 200 is rotated to be connected with the outer side of the front panel 110, the driving device 300 drives the top end of the infrared radiation module 200 to rotate, the bottom end of the infrared radiation module 200 is used as a rotating shaft, the rotating arm for driving the infrared radiation module 200 to rotate by the driving device 300 is longer, and therefore the driving device 300 can drive the infrared radiation module 200 to rotate only by small force, and the driving device 300 can save more energy. Specifically, the rotation shaft of the bottom end may extend along the length direction of the front panel 110, and the driving device 300 may drive the top end of the infrared radiation module 200 to rotate in the front-back direction. Or the rotating shaft at the bottom end can also extend perpendicular to the front panel 110, and at this time, the driving device 300 can drive the top end of the infrared radiation module 200 and drive the infrared radiation module to swing left and right.

Of course, it is understood that in other embodiments, the top end of the infrared radiation module 200 is rotatably connected to the front panel 100, and the bottom end of the infrared radiation module 200 is drivingly connected to the driving device 300.

In another embodiment, it can be understood that for a wall-hanging air-conditioning indoor unit, the front panel of the air-conditioning indoor unit has a length direction along which the infrared radiation module has a first edge and a second edge arranged oppositely, the first edge is rotatably connected to the front panel 110, and the second edge is drivingly connected to the driving device 200.

Note that the longitudinal direction in the present embodiment is perpendicular to both the up-down direction and the front-back direction in fig. 1. With this arrangement, the driving device drives the second edge to rotate relative to the first edge, so that the infrared radiation module 200 can be turned in a direction perpendicular to the panel surface of the front panel 110. So that the radiation direction of the radiation surface can be changed. Specifically, the first edge may be a left edge and the second edge may be a right edge. Or the first edge is a bordered edge and the second edge is a left edge. In addition, when the first edge is rotatably connected to the front panel 110, the rotating shaft thereof may be parallel to the panel surface of the front panel 110 or perpendicular to the panel surface of the front panel 110.

Based on the above-mentioned infrared radiation module 200 has the top end and the bottom end opposite to each other, and the bottom end of the infrared radiation module 200 is rotatably connected to the front panel 110, and the driving device 300 drives the top end of the infrared radiation module 200, in this embodiment, please refer to fig. 1 to 4 in combination, the driving device 300 includes a motor and a transmission component, the motor is installed in the housing 100, the transmission component is in transmission connection with the motor, the top end of the infrared radiation module 200 is in transmission connection with the transmission component, and the transmission component drives the top end of the infrared radiation module 200 to rotate towards the direction close to the front panel 110 or the direction far away from the front panel 110.

The motor is arranged on the shell 100, and the transmission component is connected with the motor in a transmission manner, so that the driving device 300 is connected with the shell 100, the effect that the driving device 300 and the shell 100 are connected into a whole is realized, and the structure of the air-conditioning indoor unit in the technical scheme of the utility model is more compact. In this embodiment, the transmission assembly drives the top end of the infrared radiation module 200 to rotate towards the direction close to the front panel 110 or away from the front panel 110, so that on one hand, the infrared radiation module 200 can be folded close to the front panel 110, and the situation that sundries and dust fall into one side of the infrared radiation module 200 towards the front panel 110 due to an excessively large unfolding angle of the infrared radiation module 200 is avoided; on the other hand can incline downwards as far as possible when infrared radiation module 200 expandes to make the heat of radiation can reach the position that is close ground, thereby the hot-air come-up that is close ground realizes the comparatively even effect of whole indoor temperature.

Referring to fig. 1 to 4, based on the above scheme that the transmission assembly drives the top end of the infrared radiation module 200 to rotate in a direction close to the front panel 110 or in a direction away from the front panel 110, in the present embodiment, the transmission assembly includes a driving gear 310 and a rack 320; the driving gear 310 is in transmission connection with a motor; the rack 320 is drivingly connected to the top end of the infrared radiation module 200 and is engaged with the driving gear 310.

By connecting the driving gear 310 to the motor in a transmission manner, the rack 320 is connected to the top end of the infrared radiation module 200 in a transmission manner and is meshed with the driving gear 310, so that the rack 320 is driven to move along the extending direction when the driving gear 310 rotates, and the rack 320 drives the top end of the infrared radiation module 200 to move. Since the bottom end of the infrared radiation module 200 is rotatably coupled to the front panel 110, the top end of the infrared radiation module 200 rotates relative to the bottom end thereof when the rack 320 drives the top end to move.

Specifically, in order to realize that the rack 320 can drive the top end of the infrared radiation module 200 to rotate towards the direction close to the front panel 110 and away from the front panel 110, one end of the rack 320 can be connected with one side of the infrared radiation module 200 towards the front panel 110, and the other end extends towards the direction away from the infrared radiation module 200 towards one side of the front panel 110; alternatively, one end of the rack 320 may be connected to a side of the infrared radiation module 200 away from the front panel 110, and the other end extends in a direction away from the front panel 110 toward the infrared radiation module 200.

Further, referring to fig. 1 to 4, the motor, the driving gear 310 and one end of the rack 320 are all disposed inside the housing 100, and the other end of the rack 320 extends out of the front panel 110 and is in transmission connection with the top end of the infrared radiation module 200.

By arranging the motor, the driving gear 310 and one end of the rack 320 inside the housing 100, the housing 100 has a better protection effect on the motor, the driving gear 310 and one end of the rack 320, and prevents impurities or dust from falling into the motor, the driving gear 310 and one end of the rack 320 to affect the driving effect on the infrared radiation module 200.

Referring to fig. 1, 5 and 6, the present invention provides an embodiment of an infrared radiation module 200, in which the infrared radiation module 200 includes a back plate 210, a mesh 220 and an infrared radiation element 230; the back plate 210 is rotatably connected to the front plate 110; the mesh enclosure 220 is covered on one side of the back plate 210 departing from the front panel 110, and encloses with the back plate 210 to form an installation cavity; the infrared heat radiating member 230 is provided in the installation cavity, and the infrared heat radiating member 230 has a radiation surface.

The infrared heat radiation component 230 in this embodiment is used for emitting infrared rays and carrying out infrared heat radiation outwards, and the installation cavity that closes formation is enclosed with the screen panel 220 through locating the infrared heat radiation component 230 to make screen panel 220 and backplate 210 have the guard action to infrared heat radiation component 230. The infrared heat radiation member 230 has a radiation surface so that the radiation surface can radiate heat indoors.

Specifically, referring to fig. 1, fig. 5 and fig. 6, the infrared heat radiation assembly 230 includes a heating body 231 and a radiation plate assembly, the heating body 231 is disposed in the installation cavity, and a gap is formed between the heating body 231 and the back plate 210; the radiant panel assembly is disposed in the mounting cavity and spaced from the heating body 231, and the radiant panel assembly has a radiating surface.

The heating body 231 is used to emit heat, and the heating body 231 may be an infrared heating body, that is, the infrared heating body emits infrared rays to the outside to heat the surrounding environment. The radiation plate component and the heating body 231 are arranged at intervals, so that the radiation plate component can be prevented from being burnt by the heating body 231; and the radiation plate assembly is disposed in the mounting cavity, and can be protected by the mesh enclosure 220 and the back plate 210, and the user can be prevented from accidentally touching the heating body 231 and the radiation plate assembly to scald the user. It can be understood that the heating body 231 is a far infrared heating body 231, and the material of the far infrared heating body may be silicon carbide, carbon fiber, graphene, or the like, or the infrared heating body may be an infrared metal tube or an infrared quartz tube, or the like.

Specifically, referring to fig. 1, fig. 5 and fig. 6, the radiation plate assembly may only include one radiation panel 2322, the radiation panel 2322 may be disposed on a side of the heating body 231 away from the back plate 210, and a distance is provided between the radiation panel 2322 and the heating body 231, so that heat emitted by the heating body 231 can be radiated through the radiation panel 2322, so that heat emitted by the heating body 231 can be radiated more uniformly through the radiation panel 2322, and the radiation panel 2322 can also protect the heating body 231, thereby preventing the heating body 231 from falling down through the mesh enclosure 220. Or the radiation plate assembly may include only the reflective layer 2321, and the reflective layer 2321 is disposed on a side of the back plate 210 facing the heat generating body 231, so that the infrared ray radiated from the heat generating body 231 may radiate the infrared ray indoors by the reflection of the reflective layer for infrared heat radiation. Alternatively, the radiation plate assembly may include both the radiation plate 2322 and the reflective layer 2321.

In this embodiment, in order to have a better radiation effect, the radiation panel 2322 includes a reflection layer 2321 and a radiation panel 2322, the reflection layer 2321 is disposed on one side of the back plate 210 facing the heat generating body 231, and is spaced from the heat generating body 231; radiation panel 2322 is located the one side that generates heat body 231 deviates from backplate 210 to set up with generating heat body 231 interval, radiation panel 2322 is located the installation intracavity, and the surface that radiation panel 2322 deviates from generating heat body 231 is the radiating surface.

By simultaneously coupling the radiation panel 2322 and the reflective layer 2321; the reflective layer 2321 is disposed on one side of the back plate 210 facing the heat generating body 231, and the reflective layer 2321 is used for reflecting heat radiated by the heat generating body 231, so as to prevent the back plate 210 from reflecting most of the heat into the room through the reflective layer 2321, thereby increasing the radiation amount radiated into the room. In addition, by providing the radiation panel 2322 at a side of the heat generating body facing away from the back plate 210, the heat reflected by the reflection layer 2321 can be uniformly radiated to the room through the radiation panel 2322. Specifically, the reflective layer 2321 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 2321 is applied to the inner surface of the backplate 210. The reflective layer 2321 may be made of metal aluminum foil, silver foil plated, metal-plated polyester, or metal-plated polyimide film.

Of course, in other embodiments, the coating having a reflective effect may also be applied in other components. For example, the side of the heat generating body 231 facing the back plate 210 may be coated with a reflective coating 234. The surface shape of the reflective coating 234 may be adapted to the shape of the side of the heat generating body 231 facing the back plate 210.

Further, referring to fig. 1, fig. 5 and fig. 6, the infrared radiation module 200 further includes a heat insulating layer 233, wherein the heat insulating layer 233 is sandwiched between the back plate 210 and the reflective layer 2321; and/or the side of the heat generating body 231 facing the back plate 210 is coated with a reflective coating 234.

By further interposing the thermal insulation layer 233 between the reflective layer 2321 and the back plate 210, a part of heat passing through the reflective layer 2321 can be isolated by the thermal insulation layer 233, so as to prevent the back plate 210 and the housing 100 close to the back plate 210 from being damaged by high-temperature heat. Specifically, the insulating layer 233 may be made of polyurethane, polystyrene, polyvinyl chloride, polyethylene, phenolic resin, or the like.

Further, referring to fig. 1, fig. 5 and fig. 6, the radiation surface may be a plane or an arc surface.

The radiation surface is set to be a plane, so that radiation directivity is good when heat is radiated. The radiation surface is set to be the cambered surface, so that the radiation angle of the radiation surface is wider. For example, when the infrared radiation module 200 has the radiation panel 2322, a surface of the radiation panel 2322 facing away from the housing 100 is used as a radiation surface, and the radiation surface may be a plane or an arc surface. When the surface of the radiation panel 2322 facing away from the housing 100 is a curved surface, the surface of the radiation panel 2322 facing away from the housing is outwardly convex to form the curved surface, so that the radiation range can be expanded. When the infrared radiation module 200 does not have the radiation panel 2322, but has the reflection layer 2321, a surface of the reflection layer 2321 facing the heat generating body 231 may be a radiation surface, and a surface of the reflection layer 2321 facing the heat generating body 231 may be a plane or an arc surface. When the surface of the reflecting layer 2321 facing the heating body 231 is an arc surface, the arc surface can be recessed towards the inner side of the housing 100, so that infrared rays emitted by the heating body 231 can be mostly reflected towards the front of the housing, more infrared rays emitted from the mesh enclosure 220 are ensured, and the indoor heating efficiency is improved.

Referring to fig. 1, 5 and 6, based on the scheme that the radiation surface is inclined downward, in the present embodiment, the radiation surface is a plane, and when the transmission assembly drives the infrared radiation module 200 to rotate to the unfolded state away from the front panel 110, an included angle between the radiation surface of the infrared radiation module 200 and the horizontal plane is not less than 15 ° and not more than 75 °.

The included angle between the radiation surface and the horizontal plane is defined as theta, and the theta can be 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees and the like. So set up, make the radiating surface have better radiation effect. If θ is smaller than 15 °, the radiation surface approaches a horizontal state, so that the radiation surface can radiate heat only in a direction directly below or close to directly below it, thereby making the angle of radiation small. When θ is larger than 75 °, the radiation surface is in a nearly vertical state, so that the radiation surface radiates heat in a nearly horizontal direction, and since the hot air floats upward, the radiation surface radiates only to the air above the room, and the air near the floor in the room is hardly heated by the radiation surface.

Certainly, when the radiating surface is the cambered surface, define this cambered surface and have first side and second side along the radian direction, the plane and the horizontal plane at first side and second side place also can be not less than 15, and be not more than 75.

Further, in the present embodiment, the surface area of the radiation surface is not less than 0.4m²。

With the arrangement, the area of the radiation surface can be made larger as much as possible, so that the radiation efficiency is improved, and the temperature of the air at each position in the room can be uniformly increased in a short time.

It is understood that the radiation effect is related to the temperature of the radiation surface, and in order to achieve the effect of rapid heating, the temperature of the radiation surface may be set to not less than 60 ℃ when the infrared radiation module 200 is in the on state. When the temperature of the radiation surface is less than 60 ℃, the temperature of the radiation surface is lower, so that the heating efficiency of indoor air is reduced, and the heating effect cannot be quickly realized. Further, alternatively, the temperature of the radiation surface may be not less than 80 ℃ and not more than 250 ℃. For example, the temperature of the radiation surface may be 80 ℃, 85 ℃, 90 ℃, 95 ℃, 100 ℃, 105 ℃, 110 ℃, 115 ℃, 120 ℃, 125 ℃, 130 ℃, 135 ℃, 140 ℃, 145 ℃, 150 ℃, 155 ℃, 160 ℃, 165 ℃, 170 ℃, 175 ℃, 180 ℃, 185 ℃, 190 ℃, 195 ℃, 200 ℃, 205 ℃, 210 ℃, 215 ℃, 220 ℃, 225 ℃, 230 ℃, 235 ℃, 240 ℃, 245 ℃, 250 ℃ or the like. So set up, then can guarantee the higher heating efficiency of radiant surface to indoor air on the one hand, on the other hand still avoids increasing the heating cost. It can be understood that when the temperature of the radiation surface is less than 80 ℃, the temperature of the radiation surface is low, and thus the heating efficiency for the indoor air is poor; when the temperature of the radiation surface is more than 250 deg.c, the temperature of the radiation surface is excessively high, thereby increasing the heating cost.

In addition, in this embodiment, the ratio of the temperature of the radiation surface to the surface area of the radiation surface also needs to be ensured within a relatively suitable range, so as to improve the heating efficiency and achieve the effect of rapid heating. In this embodiment, when the infrared radiation module 200 is in the on state, the ratio of the temperature of the radiation surface to the surface area of the radiation surface may be set to be not less than 15 ℃/m². If the ratio of the temperature of the radiation surface to the surface area of the radiation surface is less than 15 ℃/m²The temperature of the radiation surface per unit area is lowered, and the radiation efficiency of the radiation surface per unit area is lowered, thereby affecting the radiation efficiency of the entire radiation surface.

Further, as shown in fig. 1 or fig. 2, the housing 100 is provided with an air inlet 101 and an air outlet 102, an air duct 103 is formed in the housing 100, one end of the air duct 103 is communicated with the air inlet 101, and the other end of the air duct 103 is communicated with the air outlet 102; the heat exchanger 400 is arranged in the air duct 103 and close to the air inlet 101; the wind wheel 150 is disposed in the air duct 103 and spaced from the heat exchanger 400 in a direction from the air inlet 101 to the air outlet 102.

It should be noted that the wind wheel 500 and the heat exchanger 300 are arranged at intervals along the direction from the air inlet 101 to the air outlet 101, and then the wind wheel 500 is arranged on one side of the heat exchanger 300 away from the air inlet 101; or the wind wheel 500 may be disposed on a side of the heat exchanger 300 facing the air inlet 101. By arranging the heat exchanger 400 close to the air inlet 101 and arranging the wind wheel 500 and the heat exchanger 300 at intervals in the direction from the air inlet 101 to the air outlet 101, the wind blown in through the air inlet 101 can exchange heat through the heat exchanger 400 under the action of the wind wheel 500, and then is blown out along the direction from the air duct 103 to the air outlet 102 under the action of the wind wheel 150. The infrared radiation module 200 may or may not avoid the air inlet 101 and the air outlet 102. When the infrared radiation module 200 is moved away from the air inlet 101 and the air outlet 102, the arrangement of the infrared radiation module 200 does not affect the air inlet volume at the air inlet 101 and the air outlet volume at the air outlet 102, so as to ensure that the indoor unit of the air conditioner in the technical scheme of the present invention can achieve a better heat exchange effect through the heat exchanger 400, and can also achieve a better infrared heat radiation effect through the infrared radiation module 200. Specifically, in this embodiment, the air inlet 101 may be disposed at the top or the front side of the casing 100, and the air outlet 102 may be disposed at the front lower portion of the casing 100, so that the indoor unit of the air conditioner has better air inlet and outlet effects.

Further, in order to guide the wind blown out from the wind outlet 102, a wind deflector 160 may be disposed at the wind outlet 102, and the wind deflector 160 is rotatably connected to the housing 100, so that the user can adjust the wind outlet direction by adjusting the angle of the wind deflector 160.

Referring to fig. 1 to 4, the indoor unit of an air conditioner of the present invention can have at least the following four operating states: the system comprises a refrigeration mode, a starting-up quick heating mode, an energy-saving heating mode and a non-wind-sensation mute heating mode.

When the refrigeration mode is started, the indoor unit of the air conditioner can realize the refrigeration effect only through the refrigerant circulating system of the indoor unit. When the air-conditioning indoor unit starts a startup quick heating mode, the air-conditioning indoor unit can start a refrigerant circulation system of the air-conditioning indoor unit to convectively heat, and rotate the infrared radiation module 200, so that the infrared radiation module 200 is started to radiate and heat the indoor air after the infrared radiation module 200 is unfolded to a proper angle, and then in the process of driving the refrigerant circulation by the compressor, the infrared radiation module 200 can quickly complete the process of radiating and heating the indoor air, thereby realizing the effect of quick heating when the air-conditioning indoor unit is started. When the energy-saving heating mode is started, only the heat pump can be started to perform single-cycle heating, so that the energy consumption is saved. When the silent heating mode without wind sensation is started, the infrared radiation module 200 can be only started, noise caused by rotation of a wind wheel in the air-conditioning indoor unit is avoided, and discomfort caused by blowing of the wind from the air outlet is avoided. At this time, the infrared radiation module 200 can be rotated to a proper angle to ensure a good radiation effect. In addition, when the indoor unit of the air conditioner is not opened or in the cooling mode, the infrared radiation module 200 may not be rotated, and the infrared radiation module 200 may be maintained in a state of being parallel to the front panel 110, so as to achieve the effect of folding the infrared radiation module 200; the infrared radiation module 200 may also be maintained in an angled state with respect to the front panel 110.

The present invention further provides an air conditioner, which includes an air conditioner indoor unit, and the specific structure of the air conditioner indoor unit refers to the foregoing embodiments, and since the second subject adopts all technical solutions of all the foregoing embodiments, at least all the beneficial effects brought by the technical solutions of the foregoing embodiments are achieved, and are not described in detail herein.
