Detailed Description
It is to be noted that the embodiments and features of the embodiments may be combined with each other without conflict in structure or function. The present invention will be described in detail below with reference to examples.
The ceiling is arranged at the top of a room, the ceiling type air conditioner refers to an air conditioner which is arranged in the ceiling area and can be arranged on the ceiling, and only the air outlet supplies air downwards to blow out the ceiling area; the air supply device can also be arranged below the ceiling or partially arranged below the ceiling, so that air supply is convenient, and the air supply device can be installed under the condition of limited space above the ceiling. As shown in fig. 1 to 4, the ceiling type air conditioner 10 includes a main body 100, the main body 100 includes a mounting plate 103, a compressor 109 and an evaporation heat exchanger 110 are provided on the mounting plate 103, and the evaporation heat exchanger 110 is communicated with an air suction port of the compressor 109. The air conditioner also comprises an air supply outlet 102 formed with downdraft, and an air duct communicated with the air supply outlet 102, wherein an air supply fan 152 and an evaporation heat exchanger 110 are arranged in the air duct, and the speed of the downdraft in the vertical direction is more than 0.5 m/s. Wherein, the periphery of the ceiling type air conditioner 10 is provided with a fixing part which is connected with a pull rod so as to realize the connection of the ceiling type air conditioner 10 on a roof or a traveling rack in a hoisting way. The air supply outlet 102 is arranged on the mounting plate 103, and when the air supply fan 152 works, generated air flow is subjected to heat exchange through the evaporator to form cold air flow, and the cold air flow is discharged downwards through the air duct to the air supply outlet 102 on the mounting plate 103 to form high-speed air flow, so that an air supply area is refrigerated. The ceiling type air conditioner has the advantages that cold air is conveyed rapidly from the local area downward of the air supply opening 102 for refrigeration, the requirement of users on urgent cooling in a small area can be met, if the ceiling type air conditioner 10 is installed in a kitchen, the air supply area is arranged close to the range hood, and the ceiling type air conditioner is located right below the air supply opening 102 during cooking of the users, so that the local cold air conveying in the area of the users can be achieved for refrigeration, particularly, the refrigeration effect on the heads of the users is obvious, the users can feel cool locally in the hot environment of cooking, and accordingly the comfort of the users is improved. For convenience of description, the ceiling type air conditioner 10 is simply referred to as an air conditioner in the following embodiments.
In some embodiments of the present invention, the air supply fan 152 is disposed between the air supply opening 102 and the evaporative heat exchanger 110, the air outlet end of the air supply opening 102 is located below the mounting plate 103, an air suction area is formed between the evaporative heat exchanger 110 and the air supply opening 102, the air supply fan 152 sucks air from the side of the evaporative heat exchanger 110 when operating, the air supply fan 152 is a centrifugal fan, air is thrown out from the air supply opening 102, and the velocity of the vertical component of the downward air flow is greater than 0.95 m/s. By arranging the air supply fan 152 between the air supply opening 102 and the evaporative heat exchanger 110, the air supply fan 152 draws air from the side of the evaporative heat exchanger 110 during operation, that is, the air firstly passes through the evaporative heat exchanger 110 and then is discharged through the air supply opening 102 to the wind wheel of the air supply fan 152. The existing air supply fan 152 is arranged in a mode of not only exchanging heat between the air supply outlet 102 of the air supply fan 152 and the evaporation heat exchanger, namely, the air supply fan 152 blows air to the evaporation heat exchanger 110 when the air supply fan 152 operates, the blown air is discharged from the evaporation heat exchanger 110 to the air supply outlet 102, and experiments prove that the air supply fan 152 is lower in air resistance of blowing the evaporation heat exchanger 110 by the air supply fan 152 compared with a mode of air suction from the side of the evaporation heat exchanger 110, so that the air quantity passing through the evaporator is larger, the heat exchange efficiency of the evaporation heat exchanger 110 is improved, and the refrigerating capacity is further improved. Furthermore, the air supply blower 152 is a centrifugal blower, and compared with the existing air conditioner in which the air supply blower 152 on the evaporator side is a cross-flow blower, the air volume is larger, and because an air suction area is formed between the evaporation heat exchanger 110 and the air supply opening 102 by adopting an air suction mode, the air supply volume is increased.
In some embodiments of the present invention, as shown in fig. 1 to 7, the air duct communicating with the evaporative heat exchanger 110 and the air supply fan 152 communicates with an air intake 161 of the air conditioner, and the air intake 161 is disposed away from the air supply outlet 102. As shown in fig. 6, when the air conditioner is installed, the main body 100 is installed above the ceiling 40, the lower surface of the main body 100 is flush with the lower surface of the ceiling 40, thereby forming an integral body with the ceiling 40 in appearance, the air supply opening 102 of the air conditioner supplies air downwards, and the air inlet and the air supply of the air conditioner are separated from each other at a long distance from the air passage communication distance of the air inlet and the air supply of the air conditioner due to the isolation function of the ceiling 40. At this time, even if the air inlet 161 is disposed at the body of the air conditioner and at a position close to the evaporative heat exchanger 110, if the air inlet 161 is directly the evaporator air inlet 106 on the body 100, the air discharged from the air supply outlet 102 of the air conditioner is sent downward to the downward area, most of the cold air performs cooling heat exchange with the area where the air supply outlet 102 is downward and then diffuses to the periphery of the room, and finally enters the air inlet 161 of the air conditioner above the ceiling 40 through the mounting gap between the ceiling 40 and the wall, so that the path of the air from the air supply outlet 102 of the air conditioner to the air path where the air inlet 161 enters is greatly increased, thereby realizing the disposition of the air inlet 161 away from the air supply outlet 102, and avoiding the decrease of the cooling efficiency caused by the air from the air inlet 161 directly entering the air inlet 161 without cooling the area of the room due to the proximity of the air supply outlet 102.
Further, as shown in fig. 1 to 6, the air duct includes a soft air duct, one end of the soft air duct is communicated with the air inlet 161, and the other end is communicated to the cavity where the evaporation heat exchanger 110 is located. As shown in fig. 5, an air inlet 161 is formed at one end of the soft air duct 162 far away from the air conditioner body, so that the air inlet 161 of the air conditioner is physically far away from the air supply opening 102 through the soft air duct 162, and interference between the air inlet 161 and the air supply opening 102 is better avoided. It is determined through experiments that the distance between the air inlet 161 and the air supply opening 102 is not less than 1.2 meters, and the flexible air duct 162 can be stretched to a length of not less than 1.0 meter, 1.1 meter, 1.5 meter, 2.1 meter, 3.6 meter, and 4.5 meter in order to adapt to different installation environments, and when the air inlet 161 adopts a longer stretching length, it can be better ensured that the air inlet 161 is far away from the air supply opening 102, so that the air inlet 161 has a longer distance, and interference between the air inlet 161 and the air supply opening 102 is avoided.
In some embodiments of the present invention, as shown in fig. 1 to 8, the air blowing opening 102 is divided into two or more air blowing openings 164, specifically, as shown in fig. 4 and 7, three air blowing openings 164 are provided in the figure, three air blowing openings 164 are formed by providing three cylindrical wall surfaces on a bottom plate, the three air blowing openings 164 are arranged in a straight line, and the vertical downward projection of the wind wheel of the centrifugal air blowing fan 152 is located in the area where the three air blowing openings 164 are located. Near the air outlet 164, an air guide structure is also provided for adjusting the amount of air and the direction of the air. The specific air guide structure is composed of air guide blades 104 and a rotating shaft, wherein the rotating shaft is installed on a cylindrical wall surface, the air guide blades 104 are matched with the cylindrical wall surface, so that when the air guide blades 104 are positioned at different rotating positions through the rotating shaft, the air guide blades 104 shield the size of a cylindrical air channel, the air quantity passing through an air outlet 164 is adjusted, and the air direction is adjusted through the guiding effect of the air guide blades 104.
The invention also provides a kitchen air system, which comprises the ceiling type air conditioner 10 (hereinafter referred to as air conditioner) provided by the embodiment, a positive pressure area is formed at an air supply outlet of the ceiling type air conditioner, and the kitchen air system also comprises an oil smoke exhaust device of an exhaust fan, wherein the exhaust fan forms a first negative pressure area, and the positive pressure area is communicated with the first negative pressure area. The positive pressure region is a blowing region formed by the discharge port of the air conditioner and is formed by continuous blowing. Because the positive pressure area is communicated with the first negative pressure area, part of air in the positive pressure area can enter the negative pressure area and is pumped away by the exhaust fan.
As shown in fig. 5 to 11, the oil smoke exhausting device is a range hood 20 in the drawings, but may be other oil smoke exhausting equipment such as an exhaust fan, and the range hood 20 includes a smoke collecting hood 202, a smoke inlet 201 is formed by an opening below the smoke collecting hood, an exhaust fan (not shown in the drawings) is arranged in the smoke collecting hood 202, the other end of the smoke collecting hood 202 of the range hood 20 is connected to a smoke exhaust pipe 203, the smoke exhaust pipe 203 can pass through a ceiling 40, and the other end of the smoke exhaust pipe passes through a wall of a room to enter into the building air duct 30, so that oil-containing smoke sucked from the smoke inlet 201 when the range hood works enters into the smoke exhaust pipe 203 through the smoke collecting hood 202, is finally exhausted into the building air duct 30, and is exhausted out of the room through the building air duct 30; or in other implementations, the other end of the smoke exhaust duct 203 can be directly connected to a wall of a room, such as a smoke exhaust hole reserved in a kitchen, so as to directly exhaust the oily smoke to the outside of the building air duct 30. The downward air supply area formed by the air supply outlet 102 of the air conditioner is close to the area where the range hood 20 is located, so that the position where the air supply outlet is located is in the air supply area when a user cooks in a kitchen, the air conditioner can convey cold air to the area where the user is located, the user feels cool, and heat caused by high temperature generated in cooking is reduced. Specifically, as shown by the dotted line IN fig. 9, when the air conditioner blows air downwards, the higher wind speed airflow discharged by the air conditioner forms a positive pressure region OUT with a slightly larger air pressure than the surrounding air pressure IN the downward air blowing region, and when the suction fan of the extractor hood 20 works, the continuous air suction effect is generated so that the air pressure of the airflow formed near the smoke inlet 201 of the suction fan is a slightly smaller first negative pressure region IN1 than the surrounding air pressure. Since the air supply outlet 102 of the air conditioner supplies air downward toward the area where the user is located, the positive pressure region and the first negative pressure region are communicated, which helps to circulate air of the positive pressure region into the first negative pressure region. Specifically, the downward air supply from the air supply outlet 102 of the air conditioner forms an air curtain effect, the higher-speed airflow is blown downwards from the top of the head of a user, the head area of the user is firstly cooled, so that the user experiences coolness, the low-temperature airflow carries out temperature reduction and heat exchange on the area where the user is located and then heats up, one part of the low-temperature airflow is discharged to the peripheral area, because the range hood 20 is installed at a position lower than the ceiling 40 of the installation position of the air conditioner, the smoke inlet 201 of the range hood faces downwards and is further close to the position of a kitchen range (not shown in the figure) of cooking equipment, the vertical distance of the position of the smoke inlet 201 relative to the position of the air supply outlet 102 of the air conditioner is far away, and the airflow near the air supply outlet 102 of a positive pressure area cannot directly enter the smoke inlet 201, but is firstly discharged downwards to the top of the head of the user and the lower position to cool the area where the top of the user is located firstly, after the temperature of the airflow rises relative to the temperature of the airflow of the air supply opening 102, a part of the airflow enters the smoke inlet 201, so that the air supply opening and the smoke inlet are communicated, after the positive pressure area is communicated with the first negative pressure area, the airflow of the single positive pressure area or the single negative pressure area can generate an accelerating airflow effect, so that the airflow discharged from the air supply opening 102 to a user area is accelerated, and meanwhile, the airflow entering the smoke inlet 201 is accelerated, so that the cooling effect of a user is improved, and meanwhile, the airflow entering the smoke inlet 201 is increased, and the smoking effect of the range hood is also improved. The main outward escaping oil smoke of the smoke exhaust ventilator is discharged at the upper part, because of the air curtain effect at the air supply outlet 102 of the air conditioner, the oil smoke generated in the heating pot of the cooking appliance of the user can be blocked, the diffusion of the oil smoke around the pot is reduced, and the positive pressure area is relatively close to the first negative pressure area, so that the airflow of the positive pressure area plays a role of driving the oil smoke of the first negative pressure area, more oil smoke enters the smoke inlet 201, and the smoking effect of the smoke exhaust ventilator 20 is further enhanced. Therefore, the positive pressure area formed downwards by the air supply opening 102 of the air conditioner and the first negative pressure area formed by the smoke inlet 201 of the range hood 20 are different in height, so that the refrigeration of a user is enhanced, and the smoking effect of the range hood 20 is enhanced.
Preferably, the air supply opening 102 is located on the first negative pressure region, and the air flow discharged from the air supply opening 102 enters the first negative pressure region and is discharged to the building air duct 30 through the exhaust fan of the range hood 20. As shown in fig. 6 to 9, the air supply opening 102 of the air conditioner of the range hood 20 is located on the ceiling 40 and is located higher than the smoke inlet 201 of the range hood, so that the air supply opening 102 is located higher than the first negative pressure region where the smoke inlet 201 is located, because the head of the person is generally not lower than the opening of the smoke collecting hood of the range hood, that is, not lower than the height of the smoke inlet 201, when the person is located at the positive pressure region, the cool air discharged from the air supply opening 102 at least reaches the region where the head of the person is located to cool the person, so that the user feels cool and comfortable, then a portion of the cool air enters the first negative pressure region where the smoke inlet 201 is located and is discharged into the building air duct 30 through the exhaust fan 203, and since the smoke inlet 201 sucks a portion of the cool air and discharges the cool air into the building air duct 30, the temperature of the mixed air of the oil smoke in the building air duct 30 is reduced, therefore, the condensation of the oil-containing components in the mixed gas in the building air duct 30 can be accelerated, more oil-containing components are condensed in the building air duct 30, the oil content of the flue gas finally discharged outdoors is reduced, and the pollution to the surrounding environment is reduced.
In some embodiments of the present invention, the position of the supply opening 102 with respect to the first negative pressure region may also be changed according to the installation orientation of the air conditioner. The air outlet 102 of the air conditioner has three outlets 164 arranged in a straight line, the three outlets 164 having different wind speeds, if the straight line formed by the three blow-out ports 164 is not disposed in parallel with the wall surface of the hood 202 opposite to the range hood with respect to the user, a blow-out port 164 is formed adjacent to range hood 20 i.e. adjacent to the first suction region, if the outlet port 164 having a high wind speed is close to the first negative pressure region or the outlet port 164 having the first wind speed is close to the first negative pressure region, a gradient air supply speed is formed, when the low air speed blow-out port is close to the first negative pressure area, the escaped oil smoke is continuously pressed downwards, escaped outwards and then pressed downwards, thus, air in the lower part of the air flow structure of the range hood 20 is easier to be sucked by the range hood 20, this portion of the low temperature air mixed with the cooking fumes enters the air flow structure of the range hood 20 and is then extracted.
When the high wind speed blow-out port is close to the first negative pressure region, the escaped oil smoke can be continuously pressed downwards to the range hood 20, so as to avoid escaping. If the straight line formed by the three air outlets 164 is arranged in parallel with the wall surface of the hood 202 of the range hood 20, the air outlets 164 with high wind speed and low wind speed are arranged in parallel with the first negative pressure region, so that the blocking area is maximized, and the possibility of escaping is further reduced.
In some embodiments of the present invention, the first negative pressure region of the oil smoke exhausting device includes a smoke inlet 201, and an oil accumulating portion (not shown) is disposed at the smoke inlet 201 and disposed in the smoke collecting cover 202 for collecting the condensed oil on the wall surface of the smoke inlet 201. When the range hood 20 and the air conditioner work, a part of cold air discharged from the air supply outlet 102 of the air conditioner enters the smoke inlet 201, so that the temperature of the oily smoke and the oil accumulation part of the smoke inlet 201 is reduced, the oily components in the oily smoke are easy to condense after being cooled, and more oily components are accumulated in the engine oil part, so that the oily components discharged into the building air duct 30 are reduced, the oily components in the smoke discharged to the outdoor are finally reduced, and the pollution to the surrounding environment is further reduced.
Furthermore, a cooking device such as a pot placed on a gas stove, an induction cooker and the like is generally arranged below the range hood, when the cooker is operated to heat the pot placed on the cooker, oil-containing smoke gas is generated above the pot, and part of cold air in the positive pressure area reaches the area where the cooker is located, so that the cold air can be mixed with the oil-containing smoke gas above the pot, and the temperature of the oil-containing smoke gas is reduced.
In some embodiments of the present invention, the air inlet 161 forms a second negative pressure region which is distant from the first negative pressure region by a distance of not less than 1.5 m, and the positive pressure region is between the first negative pressure region and the second negative pressure region. Specifically, as shown IN fig. 9, the air inlet 161 disposed at the ceiling 40 has a second negative pressure region IN2 IN a region below the air inlet 102, a positive pressure region OUT IN a region below the air outlet 102, a first negative pressure region IN1 IN a region below the smoke inlet 201 of the range hood, and the positive pressure region OUT is located between the first negative pressure region IN1 and the second negative pressure region IN2, so as to effectively isolate the first negative pressure region IN1 from the second negative pressure region IN 2. If the first negative pressure region IN1 and the second negative pressure region IN2 have no intermediate positive pressure region, interference between the two regions can cause a 'wind robbing' effect, so that the oily smoke which should enter the first negative pressure region IN1 is attracted by the second negative pressure region IN2, a part of the oily smoke enters the second negative pressure region IN2 and finally enters the evaporative heat exchanger 110, so that oily components are accumulated on the surface of the evaporative heat exchanger 110, the heat exchange efficiency of the evaporative heat exchanger is seriously influenced, the refrigerating capacity of the air conditioner is further reduced, and the interference generated by the two negative pressure regions which are used for sucking air is greatly reduced after the positive pressure region for exhausting air is arranged between the two negative pressure regions. And tests prove that the distance between the two negative pressure areas is not less than 1.5 meters, so that the interference between the two negative pressure areas can be further reduced.
In some embodiments of the invention, the positive pressure zone is spaced less from the first negative pressure zone than the positive pressure zone is spaced from the second negative pressure zone, e.g., the positive pressure zone center is spaced 0.5 meters from the first negative pressure zone center and the positive pressure zone center is spaced 1 meter from the second negative pressure zone center. At the moment, more cold air discharged by the positive pressure area enters the low-pressure negative pressure area to effectively cool the oily smoke of the first negative pressure area, finally reduce the amount of oily components in the outdoor smoke, and effectively avoid the interference between the cold air of the positive pressure area and the hot air of the second negative pressure area, so that other areas of the room where more cold air of the positive pressure area participates are cooled and then enter the second negative pressure area, and the refrigerating effect of the air conditioner is improved.
In some embodiments of the present invention, as shown in fig. 1 to 4, the air conditioner is disposed in a casing of the main body 100, a lower portion of the casing is engaged with the mounting plate 103 to form an internal cavity, the evaporative heat exchanger 110, the compressor 109, and the air supply fan 152 are all mounted in the internal cavity, and the air conditioner may further include a condensing heat exchanger 108, which together form a basic component of the air conditioner for cooling or heating, the main body 100 is provided at one side thereof with an evaporator air inlet 106 for providing an air volume for heat exchange by the evaporative heat exchanger 110, and further provided with a condenser air inlet 171 for providing an air volume for heat exchange by the condensing heat exchanger 108; or the evaporator air inlet 106 and the condenser air inlet 171 can be combined into one air inlet, and the chambers where the evaporation heat exchanger 110 and the condensation heat exchanger 108 are located are simultaneously communicated through one air inlet so as to simultaneously provide the air volume for heat exchange. An air outlet 101 is provided at the other side of the body 100 to discharge the air quantity after heat exchange by the condensing heat exchanger 108. As a specific installation scenario of the air conditioner, when the air conditioner is installed in a kitchen, as shown in fig. 5 to 7, the air conditioner is installed at a position where the ceiling 40 is located, the bottom of the air conditioner is located at the height of the ceiling 40, other positions of the body 100 are located above the ceiling 40, the body is provided with an evaporator air inlet 106 and a condenser air inlet 171, the range hood 20 is installed in a region close to the lower side of the air supply outlet 102, wherein the evaporator air inlet 106 is connected with the air inlet 161 through a flexible air pipe 162, so that the air inlet is far away from the region where the range hood 20 is located, the amount of oil-containing flue gas in air entering the air inlet 161 is reduced as much as possible, and the excessive oil-containing flue gas is prevented from entering the surface of the evaporation heat exchanger 110 to affect the heat exchange efficiency thereof. The air outlet 101 of the air conditioner is connected with an exhaust air pipe 163, and the other end of the exhaust air pipe 163 and the smoke exhaust air pipe 203 are converged by a three-way pipe and then discharged into the building air duct 30.
In some embodiments of the present invention, as shown in fig. 1, 13 to 17, the air outlet 102 of the air conditioner is disposed at the bottom of the air conditioner, specifically on the air conditioner mounting plate 103, and the light emitting assembly 130 is disposed around the air outlet 102 for displaying the working state of the ceiling type air conditioner; the light emitting assembly 130 includes a first light emitter 131b and a light guide channel toward which the first light emitter 131b faces, and the air supplied from the air supply opening 102 has a component equal to the light guide direction of the light guide channel. The air volume in the same direction as the light guide direction of the air blown therein means a region in which the light emitted from the first light emitter 131b is partially or completely overlapped with the air blowing direction of the air blowing port 102 after being guided by the light guide channel.
Wherein the light emitting assembly 130 may be disposed completely around the air blowing opening 102 or partially around the air blowing opening 102, the operation state of the air conditioner is indicated by the display state of the first light emitter 131b such as different colors, blinking frequencies, etc. The first light 131b assembly can be an integral component, and thus can be disposed completely around or partially around the air input 102, such as the integral component of the light assembly 130 shown in fig. 1 disposed completely around the air input 102; or the first luminous body 131b assembly may be composed of a plurality of independent first luminous body 131b sub assemblies, and the first luminous body 131b sub assemblies are sequentially arranged around the air supply opening 102, thereby realizing the effect of surrounding the air supply opening 102 on the whole display.
Since the display area is larger than the dot-shaped display area of the indicator lamp type of the conventional air conditioner, that is, the dot-shaped display is converted into the planar display, and the air outlet 102 generally supplies air to the position where the user is located, the user can easily see the display area, and the user can see the light emitting state of the first light emitter 131b around the air outlet 102 by only slightly raising the head, so that the user can conveniently know the current working state of the air conditioner, and the user experience is improved.
Alternatively, the light guide direction is a direction toward the user area, and the air blowing direction of the air blowing port 102 is a direction toward the user area. Taking the examples shown in fig. 1 to 3 as examples, the light emitting component 130 and the air supply opening 102 are installed on the installation plate 103, and when the air conditioner is hung on the ceiling of a room, the air supply opening 102 can be set for the area where a user is located, so that the air supply direction is toward the user area, the light emitting component 130 is also located above the user, and the light guide direction is also located in the user area, thereby facilitating the user to check.
In some embodiments of the present invention, as shown in fig. 10 to 12, the air blowing opening 102 is formed with a vertically arranged air duct wall surface formed in a cylindrical shape, which is disposed adjacent to the light emitting assembly 130. Thus, a cylindrical air outlet 164 is formed in the air blowing port 102, and the three air outlets 164 are arranged in a line, and the radial cross section of the cylinder may be circular, square, triangular, or the like, and in the figure, the circular shape is a cylindrical shape. In the figure, three air outlets 164 are arranged close to each other along one side parallel to the mounting plate 103. An air guide structure for adjusting the air volume and the air direction is also provided near the air outlet 164. The specific air guide structure is composed of air guide blades 104 and a rotating shaft, the rotating shaft is installed on the cylindrical wall surface, the air guide blades 104 are matched with the cylindrical wall surface, when the air guide blades 104 are located at different rotating positions through the rotating shaft, the air guide blades 104 shield the size of a cylindrical air channel, air quantity passing through an air outlet 164 is adjusted, the air direction is adjusted through the guiding effect of the air guide blades 104, and therefore the requirement of a user on the directional air supply direction is better met.
In some embodiments of the present invention, as shown in fig. 12 to 17, the light emitting assembly 130 includes a cover 132 and a first light emitting plate 131, a first light emitting body 131b is mounted on the first light emitting plate 131, a solid light guiding channel is disposed in a local area of the cover 132, a gas light guiding channel is disposed between the cover 132 and the first light emitting body 131b, and at least one side vertical edge of the cover 132 is an opaque edge, and the opaque edge is an opaque layer disposed outside the transparent material. When the first light emitter 131b assembly is mounted on the mounting plate 103, the first light emitter 131b is mounted in the accommodating space formed by the side edge and the bottom edge of the cover 132, and a space is formed between the first light emitter 131b and the upper wall surface of the cover bottom edge 132c of the cover 132, so that a gas light guide channel is formed, and light emitted by the first light emitter 131b is scattered into the accommodating space of the cover 132. The cover 132 is made of a transparent material, and an opaque layer is coated on the side of the cover 132 to prevent light from passing through the side, wherein the opaque layer may be coated on the inner wall surface or the outer wall surface of the side, preferably on the inner wall surface, so that the cover 132 looks uniform from the outside. The side edge of the cover 132 is made of opaque material, and the bottom edge of the cover 132 is made of transparent material, so as to form a solid light guide channel, so that the light emitted by the first light-emitting body 131b is only transmitted out after being guided by the cover bottom edge 132c, and at least forms partial coincidence with the air supply direction of the air supply opening 102, so that the light is emitted toward the area where the user is located, and the user can conveniently check the light. Preferably, the bottom edge 132c of the cover is thicker than the opposite side edge, so that the light guide channel formed by the bottom edge forms a refractive light gathering effect on the light, and the light gathered by the light guide channel is more towards the air supply opening 102, and is more repeated with the air supply direction, thereby being more convenient for the user to see.
In some embodiments of the present invention, as shown in fig. 14 and 9, the cover 132 includes two side vertical edges, namely, an outer vertical edge 132d and an inner vertical edge 132e, which surround a cavity with the cover bottom edge 132c of the cover 132, the first light emitter 131b is installed in the cavity, at least the outer vertical edge 132d of the two side vertical edges is a non-transparent edge, or both the two side vertical edges are non-transparent edges, and only the cover bottom edge 132c transmits light, so that the light emitted by the first light emitter 131b is prevented from leaking from the outer vertical edge 132d to affect the overall display effect.
Further, as shown in fig. 9 to 14, the cover 132 is provided with a step portion, the step portion specifically includes a step bottom 132b and a step top 132a, the solid light guide channel is disposed on the step top 132a, the step bottom 132b is opaque, and the side vertical edge is a side edge of the step bottom 132 b; the top step surface of the step top 132a is a light-transmitting surface, and the side edge of the step top 132a is a light-opaque surface. Wherein the step top 132a and the step bottom 132b are disposed adjacent to the cylindrical wall surface of the air outlet 164 toward one side of the air outlet 102, the sides thereof may be coated with an opaque material, the sides and the bottom step surfaces of the step bottom 132b are coated with an opaque material, and the sides of the step top 132a are coated with an opaque material, so that only the top step surface of the step top 132a is left to allow light to pass through, so that the light emitted from the first light emitter 131b reaches the solid light guide channel disposed with the step top 132a and can only be emitted from the top step surface, thereby forming an aperture with a suitable width around the wall surface of the air outlet 164, and the aperture width is determined by the width of the step top surface. Since the thickness of the step top 132a is larger than that of the step bottom 132b, the solid light-guiding channel can be relatively thick, thereby forming a better light-focusing effect.
When the air conditioner is operated, the cold air is sent out from the air supply opening 102, so that the temperature of the cylindrical wall surface of the air outlet 164 is lower than the ambient temperature, the temperature of the air in the narrow space between one side edge of the step top 132a and the step bottom 132b facing the air supply opening 102 and the cylindrical wall surface is reduced, the temperature of the step top 132a and the step bottom 132b facing one side edge of the air supply opening 102 is reduced, finally, the temperature in the cavity provided with the first luminous body 131b is reduced, and the operating temperature of the luminous body is reduced, so that the operating life of the luminous body is prolonged. At the same time, the blow-out port 164 has a temperature raising effect, and is prevented from being condensed due to a local low temperature.
Further, the bottom side of the step bottom 132b is coated with an opaque material, and only the bottom of the step top 132a is left as a transparent layer, so that light enters the solid light guide channel only from the bottom of the step top 132a, since the bottom of the step bottom 132b is the peripheral portion of the bottom side of the step, which is located in the outer side region of the bottom of the cover 132, if the outer side region is light-permeable, light is easily leaked from the bottom of the cover 132, thereby affecting the overall display effect.
In some embodiments of the present invention, the first light emitter 131b is located at or partially at a projection area where the step top 132a is located. As shown in fig. 9, the first light emitter 131b is disposed close to or opposite to the projection area of the step top 132a, which is beneficial for the light emitted by the first light emitter 131b to enter the solid light guide channel where the step top 132a is located as much as possible, thereby increasing the brightness of the aperture formed by the display module.
In some embodiments of the present invention, the light emitting assembly 130 is disposed at a lower side of the mounting board 103 and is formed with a boss 111 protruding downward, the first light emitter 131b is disposed on the first PCB 131a, and the first PCB 131a is detachably fixed on a face of the boss 111, a wire passing hole (not shown) is disposed on the mounting board 103, and a power supply wire electrically connected to the first PCB 131a passes through the wire passing hole. As shown in fig. 9 to 14, a downward boss 111 is formed around a peripheral region of the air blowing port 102, and the first light emitter 131b is mounted on the first PCB 131a, and the first PCB 131a is detachably coupled to the boss 111. Specifically, the boss 111 can be provided with a screw hole, the first PCB 131a is provided with a through hole, and the first PCB 131a is fixed on the boss 111 surface by a screw, wherein the first light emitter 131b can be an LED lamp, preferably an LED lamp packaged by a chip, and can be welded on the first PCB 131a, a control circuit board (not shown in the figure) of the air conditioner is installed in a space on one side of the mounting plate 103 of the air conditioner where the compressor 109 is installed, the control circuit board is connected with a wire for supplying power to the light emitting assembly 130, and the wire is electrically connected with the first PCB 131a by passing through a wire passing hole on the mounting plate 103, so that the light emitting operation of the first light emitter 131b controlled by the control circuit board is realized. Through fixing the first PCB 131a on which the first light emitter 131b is mounted on the surface of the boss 111, when the cover 132 of the light emitting assembly 130 is mounted on the mounting plate 103, the first light emitter 131b is inserted into the cavity of the cover 132, and through the attachment of the side edge of the cover 132 and the side edge of the boss 111, a better sealing effect on light is achieved, light leakage from the gap where the side edge of the cover 132 contacts the mounting plate 103 is avoided, and thus the overall aperture display effect is affected.
In some embodiments of the present invention, the air conditioner further includes a second light-emitting panel 120, in addition to the air conditioner structure of the above embodiments, the second light-emitting panel 120 includes a plurality of second light-emitting bodies 122, which emit light toward the user area, and is disposed on the lower bottom surface of the mounting board 103, and further includes a space layer disposed between the second light-emitting panel 120 and the mounting board 103, and a light-transmitting cover 105 disposed on the outer side, and a space layer disposed between the second light-emitting panel 120 and the light-transmitting cover 105. As shown in fig. 1 and 9 to 14, a plurality of second light emitters 122 are mounted on the second light emitting plate 120, the specific structure of the second light emitting plate may be the same as the mounting structure of the first light emitter 131b of the light emitting assembly 130, the second light emitters 122 are also LED lamps packaged by a chip, and are soldered to the second PCB board 121 of the second light emitters 122, the second PCB board 121 is also electrically connected to the control circuit board of the air conditioner through the through holes disposed on the mounting board 103 by wires, so as to control the operating state of the second light emitters 122 by the control circuit board, and the light emitted by the second light emitting plate 120 is emitted through the translucent cover 105, so as to perform the functions of illumination and indication. Through setting up the luminescent plate at mounting panel 103 of air conditioner, because the regional area of mounting panel 103 is great, consequently make whole air conditioner still have the illumination function concurrently, bring the facility for user's use. In the process of cooling or heating of the air conditioner, the evaporator 110 or the condenser 108 of the air conditioner condenses cold water to flow to the upper bottom surface of the mounting plate 103, so that the temperature of the entire mounting plate 103 is lower than that of the surrounding environment, and thus the temperature of the mounting plate 103 is lowered to the second light emitter 122 on the second PCB 121 through heat conduction of the space layer between the light emitting plate and the mounting plate 103, which is beneficial to maintaining the temperature of the second light emitter 122 not too high to increase the service life and stability of the air conditioner. And through setting up and the suitable space layer of distance between second luminescent plate 120 and the printing opacity cover 105 for the light that a plurality of second luminophors 122 sent forms the even plain noodles of luminance on printing opacity cover 105 after the light scattering, has avoided second luminophor 122 to make the light of second luminophor 122 form the inhomogeneous facula of luminance on printing opacity cover 105 apart from printing opacity cover 105 too closely, with this influence holistic display effect. The light transmissive cover 105 may be formed of an opaque material that is light transmissive, or may be formed of a transparent material and coated with an opaque layer on one side of the light transmissive cover 105.
When the air conditioner is operated, cold air is conveyed outwards from the air supply opening 102, so that the temperature of the cylindrical wall surface of the air outlet 164 is lower than the temperature of the ambient environment, the low temperature of the cylindrical wall surface conducts and cools the air of the two separation layers, the temperature in the cavity between the mounting plate 103 and the light-transmitting cover 105 is reduced, the operation temperature of the second light-emitting body 122 in the cavity is reduced, and the service life of the air conditioner can be effectively prolonged. At the same time, the blow-out port 164 has a temperature raising effect, and is prevented from being condensed due to a local low temperature.
Because the mounting plate is provided with the compressor 109, the fan at the evaporator 110 side and the fan at the condenser 108 side, when the air conditioner works, the three components generate larger noise in a cavity formed by the shell 106 and the mounting plate 103, the noise is transmitted to the other cavity formed by the mounting plate 103 and the light-transmitting cover 105 through the mounting plate 103, and the sound wave of the noise reduces the sound wave energy before the sound wave is reflected back and forth between the second light-emitting plate 120 and the mounting plate 103 through the spacing layer formed between the second light-emitting plate 120 and the mounting plate 103, so that the noise reduction effect is achieved; and the noise further has the space layer through second luminescent plate 120 and printing opacity cover 105 between for the sound wave of noise further reduces the sound wave energy and further falls the noise in the back and forth reflection between second luminescent plate 120 and printing opacity cover 105, thereby makes the noise fall twice through these two space layers and makes an uproar, from the effectual reduction of the noise that transmits to the air conditioner, thereby plays obvious noise reduction effect. High noise sources are prevented from being formed at the top of the head of a user, and the use experience of the user is reduced.

As shown in fig. 1 to 9, a through hole adapted to the shape of the air blowing opening 102 is provided at the position of the light-transmitting cover 105 corresponding to the air blowing opening 102, the cylindrical wall surface of the air blowing opening 164 extends out from the through hole of the light-transmitting cover 105, and the aperture of the through hole is larger than that of the cylindrical wall surface, so that the top step surface of the cover 132 of the light-emitting component 130 is exposed out from the gap between the through hole and the cylindrical wall surface, thereby forming a light ring with uniform light emission at the air blowing opening 102, thereby playing an indicating role, and the light of the light ring is guided to the area of the user through the solid light guide channel, thereby increasing the aesthetic effect of the whole display and being convenient for the user to view.
