Description

Air conditioner Technical background The present invention relates to an air conditioner, and more particularly to an air conditioner having various air discharge methods and configured to control the flow of discharged air. Background industry In general, air conditioners are devices that are configured to adjust temperature, humidity, air flow, distribution, etc., compatible with human activity by using a cooling and dedusting cycle. Compressor, condenser, evaporator, blower fan, etc. are provided as components of the cooling cycle. Air conditioners can be divided into the following types: -Split type air conditioner in which the indoor unit and outdoor unit are installed separately. -Integrated type air conditioner in which the indoor unit and outdoor unit are installed integrally in one compartment. The indoor unit of the split-type air conditioner includes a heat exchanger configured to exchange heat with air entering the panel, and a blower fan configured to draw air into the panel and blow it into the indoor space. The indoor unit of a conventional air conditioner is constructed in such a way that the heat exchanger is minimized and the volume and speed of the air increase with the increase in the RPM of the blower fan. Accordingly, the discharge temperature decreases and by forming a long and narrow path, the discharged air is discharged into the indoor space. When the user directly comes into contact with the discharged air, he feels comfortable and cool. In addition, when the rotation speed of the blower fan is increased to achieve high air velocity, the noise increases. In the case of a radiant air conditioner configured to provide air ventilation without using a blower fan, a large panel is required to achieve the same performance as a blower fan air conditioner. In addition, the cooling speed is very low and the construction costs are high. Technical problem One aspect of the invention provides for differential control of the exhaust airflow of an air conditioner.

In the following, examples according to the present invention will be explained in detail with reference to the accompanying drawings. The refrigeration cycle of an air conditioner consists of a compressor, condenser, expansion valve, and evaporator. A refrigerant undergoes a series of compression, condensation, expansion, and evaporation cycles, and after the hot air is exchanged with the refrigerant, the cold air is transferred to the indoor space. The compressor compresses the refrigerant gas at high temperature and pressure, and then discharges the refrigerant gas, and the discharged refrigerant gas enters the condenser. The condenser condenses the compressed refrigerant into a liquid state and transfers heat to the surrounding environment through the condensation process. The expansion valve condenses the liquid refrigerant at high temperature and pressure into a liquid refrigerant at low pressure through the condenser. The evaporator evaporates the refrigerant expanded by the expansion valve. Due to the heat exchange between the cold object and the refrigerant and by utilizing the latent heat of evaporation of the refrigerant, the evaporator produces a cooling effect and returns the refrigerant gas at low temperature and pressure to the compressor. The indoor air temperature can be adjusted by the above-mentioned cycle. The outdoor unit of the air conditioner is the part that includes the compressor and the external heat exchanger of the refrigeration cycle. The expansion valve can be in the indoor unit and the outdoor unit, and the internal heat exchanger is in the indoor unit of the air conditioner. The invention relates to an air conditioner configured to cool an indoor space, the outdoor heat exchanger acting as a condenser and the indoor heat exchanger acting as an evaporator. Hereinafter, for convenience, the indoor unit including the indoor heat exchanger will be referred to as an air conditioner, and the indoor heat exchanger will be referred to as a heat exchanger.

Although not shown in the figures, a filter (not shown) may be connected to the suction port 14 of the housing 10. The filter absorbs foreign matter such as dust contained in the outside air entering the suction port 14. In addition, the air conditioner 1 has an additional filter in the housing 10 configured to absorb and filter foreign matter such as dust, odor particles, etc. contained in the air. A counter-flow fan formed corresponding to the shape and length of the housing 10 can be used as a blower fan 30. That is, the blower fan 30 may be arranged so as to have a rotating shaft parallel to the suction port 14 and the first blower port 110 and the second blower port 210. The blower fan 30 is rotatably installed in the rear housing 12 and is rotated by a fan motor (not shown) located in the rear housing 12.

A set of vanes 51 designed to guide the discharged air through the path formed by the stabilizer 50 and the rear guide surface 19 in a horizontal direction may be provided on the lower surface of the stabilizer 50. The set of vanes 51 guide the air discharged by the horizontal rotation of the set of vanes 51 in a horizontal direction. The first door 120 and the guide blade 320 are rotatably mounted on the first support member 40. In addition, a first motor 130 designed to operate the first door 120 and a second motor 330 designed to operate the guide blade 320 can be mounted on the first support member 40. The first door 120 includes a plurality of first hinge protrusions 124 and a first motor connection shaft 125. A plurality of first hinge protrusions 124 of the first door 120 are connected to a plurality of first hinge protrusions 41 provided on the first support member 40, and the first motor connection shaft 125 of the first door 120 is connected to a first motor 130 installed on the first support member 40. Since the first hinge protrusions 124 and the first motor connection shaft 125 are provided coaxially, the first door 120 rotates the first motor 130. The first door 120 directs the air discharged from the first blower port 110 in the vertical direction by the vertical rotation of the first door 120. The first 120 pages include the following sections: -First blade 122 configured to open or close first blower port 110, -A second blade 123 separate from the first blade 122 configured to overlap at least a portion of the first blade 122; That is, the second blade 123 is provided separately from the first blade 122, but its width is smaller than the width of the first blade 122. A number of first holes 121 formed in the first door 120 may be formed in the first blade 122. Although not shown in the figures, a number of first holes may also be formed in the second blade 123. Meanwhile, when holes are not formed in the second blade 123 of the first door 120, the air blowing from the blower fan 30 is helped to be curved relative to the duct 310. The guide blade 320 includes a plurality of second hinge protrusions 324 and a second motor connection shaft 325. A plurality of second hinge protrusions 324 of the guide blade 320 are connected to a plurality of second hinge protrusions 42 provided on the first support member 40, and the second motor connection shaft 325 of the guide blade 320 is connected to a second motor 330 mounted on the first support member 40. Since the second hinge protrusions 324 and the second motor connection shaft 325 are provided coaxially, the guide blade 320 is rotated by the second motor 330. Although not shown in the figures, the guide blade is provided with a rotary handle for manual adjustment to the first or second position by the user. The guide blade has a rotary handle for manual adjustment. The guide vane 320 includes a plurality of fourth holes 321 to flow air into the first blower port 110 in the second position (where the inlet 311 of the duct 310 is open). That is, when the first blower port 110 and the second blower port 120 are closed, the guide vane 320 flows air into the first blower port 110 through a plurality of fourth holes 321 in the second position (which directs the airflow blown from the blower fan 30 into the second blower port 210). The housing 10 includes a second support member 60 on which other components of the air conditioner 1 are mounted. The second support member 60 is connected to the front outer side surface 312 of the front housing 11. That is, the second support member 60 is located in the duct 310 and the second door 220 is rotatably mounted on the second support member 60. Holes are provided on the upper surface of the second support member 60 so that the duct 310 is not blocked by the second support member 60.

Since the third hinge protrusions 224 and the third motor connection shaft 225 are provided coaxially, the second door 220 is rotated by the third motor 230. The second door 220 directs the air discharged from the second blower port 210 in the vertical direction by the vertical rotation of the second door 220. The air conditioner 1 according to an embodiment of the present invention is variously adjusted and controls the flow of discharged air, such as the direction, volume, etc. of the discharged air from the first door 120, the second door 220, and the guide vane 320. Figure 6 is a cross-sectional view showing a low wind state of an air conditioner according to an example of the invention. Figure 7 is a cross-sectional view showing a high wind state of an air conditioner according to an example of the invention. Figure 8 is a cross-sectional view showing a no wind state of an air conditioner according to an example of the invention. Referring to FIG. 6 , the first door 120 rotates around the protrusions of the first hinge 124 to open the first blower port 110, and the second door 220 closes the second blower port 210. The first blower port 110 is provided at the bottom of the housing 10, specifically at the bottom surface of the rear housing 12, and when the air conditioner 1 operates in a state in which the first blower port 110 is opened, wind having a strong air flow velocity and a wind direction directed forward and downward is discharged. The air conditioner 1 according to the invention can be mounted on a wall, and it is assumed that the air conditioner 1 is mounted on the upper part of the wall, and an operation mode in which the first blower port 110 of the air conditioner 1 is open is defined as a downward wind mode or a direct wind mode. In the direct wind mode, because strong wind is blown directly to the user, it is possible to provide immediate heating or cooling to the user, and indoor air ventilation is carried out quickly due to the strong wind speed and large wind volume. The first door 120 includes a first blade 122 and a second blade 123, and the second blade 123 is provided to overlap at least a portion of the first blade 122. The second blade 123 improves the directivity of the air blown into the first blower port 110. Accordingly, the first door 120 easily controls the air flow in the vertical direction caused by the second blade 123 and blows the air at a higher speed. In the downwind state, the guide blade 320 is positioned at a first position a320, which directs the air blown from the blower fan 30 in a first direction toward the first blower port 110. That is, the guide blade 320 closes the inlet 311 of the duct 310 at a first position a320 so that the air blown from the blower fan 30 is not directed toward the duct 310. Referring to FIG. 7 , the first door 120 closes the first blower port 110, and the second door 220 rotates around the protrusions of the third hinge 224 to open the second blower port 210. The second blower port 210 can be provided on the front surface of the housing 10, specifically on the front panel 13, and when the air conditioner 1 operates in a state where the second blower port 210 is open, wind having an air flow with a strong velocity and a wind direction directed forward and upward is discharged. The air conditioner 1 according to the invention can be mounted on a wall, and it is assumed that the air conditioner 1 is mounted on the upper part of the wall, and an operation mode in which the second blower port 210 of the air conditioner 1 is open is defined as an upward wind mode or an indirect wind mode. In the indirect wind mode, indoor space cooling is performed by transferring heat without blowing the wind directly to the user, and indoor air ventilation is performed quickly due to the strong speed and large volume of the wind. The lower end of the second door 220 is hinged to the housing 10 so that the air discharged from the second blower port 210 is directed in an upward direction. That is, the third hinge protrusions 224 located on the second door 220 are provided at the lower end of the second door 220, and the second door 220 rotates around the third hinge protrusions 224 to direct the air discharged from the second blower port 210 in an upward direction. In addition, the second blower port 210 can be located in the upper portion of the front panel 13 so that the air is blown close to the ceiling. In the upwind state, the guide blade 320 rotates around the protrusions of the second hinge 324 to be in the second position b320. The guide blade 320 directs the air blown from the blower fan 30 in a second path toward the second blower port 210 in the second position b320. That is, the guide blade 320 opens the inlet 311 of the duct 310 in the second position b320 so that the air blown from the blower fan 30 goes toward the duct 310. In addition, the guide blade 320 closes the path toward the first blower port 110 with the second blade 123 of the first door 120 in the second position b320. Referring to FIG. 8, the first door 120 and the second door 220 close the first blower port 110 and the second blower port 210, and the guide blade 320 moves to the second position b320 to open the inlet 311 of the duct 310. A number of third holes 313 are uniformly arranged in the front panel 13 and form the surface of the duct 310. When the first door 120 and the second door 220 close the first blower port 110 and the second blower port 210, the air blown from the blower fan 30 is discharged upward from the chamber 10 through a number of third holes 313 formed in the front panel 13. Since a number of third holes 313 are formed in the upper portion of the second blower port 210, the air blown from the blower fan 30 passes through the hole 62 located in the upper portion of the second support member 60 and moves to the upper end of the duct 310. In addition, a number of second holes 221 are provided to be uniformly located in the second door 220, and when the first door 120 and the second door 220 close the first blower port 110 and the second blower port 210, the air blown from the blower fan 30 is discharged upward from the chamber 10 through a number of second holes 221 formed in the second door 220. A number of fourth holes 321 are provided to be uniformly disposed in the guide blade 320. When the guide blade 320 is in the second position b320 and directs the air blown from the blower fan 30 toward the second blower port 210 and the first door 120 and the second door 220 close the first blower port 110 and the second blower port 210, the air blown from the blower fan 30 flows through a number of fourth holes 321 formed in the guide blade 320 toward the first blower port 110. In addition, the air blown from the blower fan 30 also flows through the gap between the guide blade 320 and the second blade 123 of the first door 120. A number of first holes 121 are provided to be uniformly arranged in the first door 120, and air flowing through a number of fourth holes 321 or a gap between the guide blade 320 and the second blade 123 of the first door 120 is discharged upwardly from the chamber 10 through a number of second holes 121 formed in the second door 220. When the air conditioner 1 operates in a state in which the first blower port 110 and the second blower port 210 are closed, wind having an air flow at a slow speed and a wind direction that spreads in all directions is discharged. The operating state of the air conditioner 1 in a state in which the first blower port 110 and the second blower port 210 are closed is defined as a no-wind state. In the no-wind state, the entire indoor space is air-conditioned gently without blowing wind directly to the user. In the downwind state, since the first blower port 110 is open, the air blown from the blower fan 30 forms a strong air flow that moves toward the first blower port 110. Therefore, the amount of air blown from the blower fan 30 and entering the duct 310 through a number of fourth holes 321 formed in the guide blade 320 is zero or very small. In the upwind mode, since the second blower port 210 and the inlet 311 of the duct 310 are open, the air blown from the blower fan 30 forms a strong air flow that passes through the duct 310 and proceeds towards the second blower port 210. Accordingly, the amount of air blown from the blower fan 30 and discharged from the chamber 10 through a number of first holes 121 formed in the first door 120 after passing through a number of fourth holes 321 formed in the guide blade 320 is zero or very small. In addition, the amount of air blown from the blower fan 30 and discharged from the chamber 10 through a number of third holes 313 formed in the chamber 10 is also zero or very small. Since no blower port is open in the no-wind state, the air blown from the blower fan 30 enters the duct 310 weaker than in the upward wind state. In addition, the air blown from the blower fan 30 is discharged from the chamber 10 at a very low speed through a number of first holes 121 formed in the first door 120, a number of second holes 221 formed in the second door 220, and a number of third holes 313 formed in the chamber 10. A number of first holes 121 formed in the first door 120, a number of second holes 221 formed in the second door 220, and a number of third holes 313 formed in the housing 10 may be formed with the same diameter. In this case, since all the holes viewed from the outside have the same diameter and appearance, they may be improved. Meanwhile, a number of first holes 121 formed in the first door 120, a number of second holes 221 formed in the second door 220, and a number of third holes 313 formed in the housing 10 may each be formed with different diameters. Preferably, each of the first holes 121 formed in the first door may have a different diameter than each of the second holes 221 formed in the second door 220 and each of the third holes 313 formed in the housing 10. Preferably, each of the first holes 121 formed in the first door may have a smaller diameter than each of the second holes 221 formed in the second door 220 and each of the third holes 313 formed in the housing 10. Referring to FIG. 8 , the first door 120 configured to cover the first blower port 110 is located closer to the blower fan 30, and the air blown from the blower fan 30 has a path that is bent by the guide blade 30 and the second blade 123 of the first door 120. When a number of first holes 121 formed in the first door 120, a number of second holes 221 formed in the second door 220, and a number of third holes 313 formed in the chamber 10 are formed with the same diameter, in a state of no wind, the flow speed of the air discharged through the number of first holes 121 formed in the first door 120 is faster than the air discharged through the number of second holes 221 formed in the second door 220 and the number of third holes 313 formed in the chamber 10. When the diameter of each of the first holes 121 formed in the first door 120 is smaller than the diameter of each of the second holes 221 formed in the second door 220 and each of the third holes 313 formed in the chamber 10, air is discharged at the same flow rate through a number of the first holes 121 formed in the first door 120, a number of the second holes 221 formed in the second door 220, and a number of the third holes 313 formed in the chamber 10. In addition, due to various other factors, the flow rate of the air discharged through the plurality of first holes 121 formed in the first door 120, the plurality of second holes 221 formed in the second door 220, and the plurality of third holes 313 formed in the chamber 10 may be different from each other. In this case, by detecting the diameter of each of the first holes 121 formed in the first door 120, the diameter of each of the second holes 221 formed in the second door 220, and the diameter of each of the third holes 313 formed in the chamber 10 or the diameter of each of the fourth holes 321 formed in the guide blade 320, the air is discharged at the same flow rate through the plurality of first holes 121 formed in the first door 120, the plurality of second holes 221 formed in the second door 220, and the plurality of third holes 313 formed in the chamber 10.

The description of the components of air conditioner 2 according to the example shown in Figures 9 to 11 is the same as the components of air conditioner 1 according to the example shown in Figures 1 to 8 and will be omitted. The air conditioner 2 according to another embodiment of the present invention is configured differently and controls flows such as direction, volume, or... of the discharged air from the first door 120, the second door 420, and the guide vane 320. Referring to FIG. 11, the first door 120 closes the first blower port 110, and the second door 420 rotates around the protrusions of the third hinge 424 to open the second blower port 410. The second blower port 410 is provided on the front surface of the housing 10, specifically on the front panel 13, and when the air conditioner 1 operates in a state in which the first blower port 110 is open, wind having a strong air flow velocity and a wind direction directed forward and upward is discharged. The air conditioner 2 according to the invention can be mounted on a wall, and it is assumed that the air conditioner 2 is mounted on the upper part of the wall, and an operation mode in which the second blower port 410 of the air conditioner 2 is open is defined as an upward wind mode or an indirect wind mode. In the direct wind mode, the indoor space is cooled by heat transfer without blowing the wind directly to the user, and the indoor air is ventilated quickly due to the strong speed and large volume of the wind. The lower end of the second door 420 is hinged to the housing 10 so that the air discharged from the second blower port 410 is directed in an upward direction. That is, the protrusions of the third hinge 424 located on the second door 420 are provided at the lower end of the second door 420, and the second door 420 rotates around the protrusions of the third hinge 424 to direct the air discharged from the second blower port 410 in an upward direction. In the upwind state, the guide blade 320 rotates around the protrusions of the second hinge 324 to be in the second position b320. The guide blade 320 directs the air blown from the blower fan 30 in a second path toward the second blower port 410 in the second position b320. That is, the guide blade 320 opens the inlet 311 of the duct 310 in the second position b320 so that the air blown from the blower fan 30 goes toward the duct 310. In addition, the guide blade 320 closes the path toward the first blower port 110 with the second blade 123 of the first door 120 in the second position b320. The second blower port 420 is located in the center of the front panel 13. When the second blower port 420 is located in the center of the front panel 13, air is blown from the blower fan 30 and is bent by the second blade 123 and the guide blade 320 of the first door 120 is blown directly in the upward direction without bending into the second blower port 420. That is, when the second blower port 420 is located in the center of the front panel 13, the air blown from the blower fan 30 is discharged through the second blower port 420 at a high speed. The second door 420 includes a third blade 422 and a fourth blade 423, and the fourth blade 423 is provided to overlap at least a portion of the third blade 422. The fourth blade 423 improves the directivity of the air blown into the second blower port 410. Accordingly, the second door 420 easily controls the air flow in the vertical direction caused by the fourth blade 423 and blows the air at a higher speed. Equal to or similar to the example shown in Figures 6 and 8, the air conditioner 2 operates in a downwind mode and a no-wind mode. The scope of this invention is not limited to the above-mentioned examples. Without departing from the spirit of the invention as defined in the claims, various other examples that can be changed by those skilled in the art are within the scope of this invention.
