However, the present invention will become apparent from the following detailed description of the preferred embodiments. The present invention is not limited to the embodiments shown and may be embodied in various different forms. However, the present embodiment is provided so that the disclosure of the present invention will be complete and complete.

[0048] A person skilled in the art will be fully informed of the scope of the invention. The present invention is defined solely by the claims. Like numbers refer to like elements throughout the specification.

[0049] FIG. 1 is a perspective view of an air conditioner according to an embodiment of the present invention, and FIG. 2 is a diagram showing an example of operation of FIG. 1. 3 is a front view of FIG. 2, and FIG. 4 is a plan view of FIG.

[0050] 1 to 4, an air conditioner 1 according to an embodiment of the present invention is provided with a case that provides an outer shape. The case 100 includes a base case 150 in which a filter 200 is provided. , includes a tower case 140 that expels air via the Coanda effect.

[0051] The tower case 140 is made up of a first tower 110 and a second tower 110 which are separated into two columns. The second tower 120 is included. In this embodiment, the first tower 110 is located on the left side, and the third tower 120 is located on the right side. The second tower 120 is located on the right side.

[0052] In this specification, the vertical direction is defined as a direction parallel to the rotation axis direction of the fan 320. The upper direction (vertical direction) is the direction in which the tower case 140 is located in the case 100. The downward direction means the direction in which the base case 150 is located in the case 100. .

[0053] The first tower 110 and the second tower 120 are spaced apart. A blowing space 105 is formed between the nozzle 101 and the nozzle 102.

[0054] In this embodiment, the blowing space 105 is open at the front, rear, and top. The upper and lower ends of the blowing space 105 are formed with equal intervals.

[0055] The tower case 140, which includes the first tower, the second tower, and the blowing space, is circular. It is formed in a frustum shape.

[0056] The outlets 117 and 127 arranged on the first tower 110 and the second tower 120, respectively, are , and discharges air into the blowing space 105. If it is necessary to separate the discharge ports, The outlet formed in the first tower 110 is called the first outlet 117, and the outlet formed in the second tower 120 is called the second outlet 118. The outlet is referred to as a second outlet 127.

[0057] The first and second outlets are arranged within the height of the blowing space. The direction across the nozzle is defined as the air discharge direction.

[0058] Since the first tower 110 and the second tower 120 are arranged on the left and right, the air discharge The exit direction can be formed in the front-rear direction or the up-down direction.

[0059] That is, the air discharge direction across the blowing space is The air outlet direction S1 includes an air outlet direction S1 and a second air outlet direction S2 formed in the up-down direction.

[0060] The air flowing in the first air discharge direction S1 is a horizontal air flow, and the air flowing in the second air discharge direction S2 is a horizontal air flow. The air becomes an updraft.

[0061] Horizontal airflow does not mean that air flows only horizontally, but rather refers to air that flows horizontally. Similarly, an updraft is a current that moves air upwards. Rather than meaning that only the upper air flows, it is understood that the flow rate of the air flowing in the upward direction is even greater. It should be.

[0062] In this embodiment, the upper and lower ends of the blowing space 105 are spaced equally apart. Unlike this embodiment, the upper end distance of the blowing space 105 is narrower than the lower end distance. It does not matter whether the area is narrow or wide.

[0063] By forming the width of the blowing space 105 constant, This allows for a more uniform flow of air in front of the pace.

[0064] For example, if the width of the upper side is different from the width of the lower side, the flow velocity on the wider side may be lower, and the flow velocity in the vertical direction may be lower. The velocity deviation can occur based on the above. The velocity deviation of the air occurs in the vertical direction. When the air pressure is increased, the air travel distance may be different.

[0065] The air discharged from the first and second outlets joins in the blowing space and , can be streamed to the user.

[0066] That is, in this embodiment, the air discharged from the first outlet 117 and the air discharged from the second outlet 127 The discharge air from the first outlet 117 is not individually circulated to the user. The air discharged from the first outlet 127 and the air discharged from the second outlet 128 are joined in the blowing space 105, and then Provided to the.

[0067] The blowing space can be used as a space where discharged air meets and mixes. In addition, the blowing space 105 is blown by the discharged air. The air behind the pace can also be circulated into the blowing space.

[0068] The air discharged from the first outlet 117 and the air discharged from the second outlet 127 enters the blowing space. By joining the first discharge port 1 and the second discharge port 2 together, the straightness of the discharged air can be improved. The discharge air from the first outlet 17 and the discharge air from the second outlet 127 are joined in the blow space. This allows the air around the first and second towers to flow indirectly in the air discharge direction. .

[0069] In this embodiment, the first air discharge direction S1 is formed from the rear to the front, and the second air discharge direction S2 is formed from the rear to the front. The direction S2 is formed from the bottom to the top.

[0070] Because of the second air discharge direction S2, the upper end 111 of the first tower 110 and the upper end 112 of the second tower 120 That is, the air discharged in the second air discharge direction S2 is No interference occurs with the case of the harmonic unit 1.

[0071] The first air discharge direction S1 allows the front end 112 of the first tower 110 and the front end 113 of the second tower 110 to The front end 122 of the first tower 110 is spaced apart from the rear end 113 of the second tower 120. The ends 123 are also spaced apart.

[0072] The first tower 110 and the second tower 120 face toward the blowing space 105 The surface facing away from the blowing space 105 is the outer surface.

[0073] The outer wall 114 of the first tower 110 and the outer wall 124 of the second tower 120 are opposite to each other. The inner wall 115 of the first tower 110 and the inner wall 125 of the second tower 120 are arranged in a mutually opposite direction. Opposite to.

[0074] When the division of the inner walls 115 and 125 is necessary, the inner surface of the first tower is the first inner wall 115. The inner surface of the second tower is a second inner wall 125 .

[0075] Similarly, if a division of the outer walls 114, 124 is required, the outer surface of the first tower is divided into the first outer wall The outer surface of the second tower is designated as 114, and the outer surface of the second tower is designated as 124.

[0076] The first outer wall 114 is formed outward from the first inner wall 115. The second inner wall 115 forms a space through which air flows. The first outer wall 124 and the first inner wall 125 are formed on the outer side of the side wall 125. It creates a space where things can flow.

[0077] The first tower 110 and the second tower 120 are formed in a streamlined shape in the direction of air flow. do.

[0078] Specifically, the first inner wall 115 and the first outer wall 114 are formed in a streamlined shape in the front-rear direction. The second inner wall 125 and the second outer wall 124 are formed in a streamlined shape in the front-rear direction.

[0079] The first outlet 117 is disposed in the first inner wall 115, and the second outlet 127 is disposed in the second inner wall 12. It will be placed at 5.

[0080] The shortest distance between the first inner wall 115 and the second inner wall 125 is defined as B0. 7 is positioned behind the shortest distance B0.

[0081] The distance between the front end 112 of the first tower 110 and the front end 122 of the second tower 120 is set as the first distance. The distance between the rear end 113 of the first tower 110 and the rear end 123 of the second tower 120 is B1. The separation distance is defined as a second separation distance B2.

[0082] In this embodiment, B1 and B2 are formed in the same manner. Either B1 or B2 may be formed longer.

[0083] The first outlet 117 and the second outlet 127 are disposed between B0 and B2.

[0084] The first outlet 117 and the second outlet 127 are located at the rear end 113 of the first tower 110 and the rear end 114 of the second tower 110 from B0. and preferably disposed adjacent to the rear end 123 of the second tower 120.

[0085] The closer the outlets 117, 127 are to the rear ends 113, 123, the more easily the core can be cooled. It is easy to control airflow through the Da effect.

[0086] The inner wall 115 of the first tower 110 and the inner wall 125 of the second tower 120 are formed by the Coanda effect. The outer wall 114 of the first tower 110 and the outer wall 124 of the second tower 120 are directly provided with the fruit. provides the Coanda effect indirectly.

[0087] The inner walls 115, 125 guide the air discharged from the discharge ports 117, 127 to the front ends 112, 1 22. That is, the air discharged from the discharge ports 117 and 127 is guided directly to the horizontal air Provides direct flow.

[0088] The air flow in the blowing space 105 also causes indirect airflow on the outer walls 114, 124. The outer walls 114, 124 create a Coanda effect on the indirect airflow. This raises the airflow and directs the indirect airflow into the shears 112, 122.

[0089] The left side of the blowing space is closed by a first inner wall 115. The right side of the blowing space 105 is closed by the second inner wall 125, but the upper side of the blowing space 105 is It will be released.

[0090] The airflow converter described below converts the horizontal airflow passing through the blow space into an updraft. The rising air current can be circulated to the open upper side of the air conditioner. This prevents direct airflow and allows for active convection of indoor air.

[0091] In addition, the width of the discharged air can be adjusted by adjusting the flow rate of the air that joins in the blow space. The widths B0, B1, and B2 of the blow space allow the first outlet 117 and the second outlet 118 to be By making the vertical length of 27 much longer, the air discharged from the first outlet and the air discharged from the second outlet The air exhaled from the mouth is blown out and can be guided to meet in the space.

[0092] 1 to 3, a case 100 of an air conditioner 1 according to an embodiment of the present invention is A base case 150 on which the filter is detachably installed, and a filter disposed above the base case 150. The tower case 140 is supported by a base case 150 .

[0093] The tower case 140 includes a first tower 110 and a second tower 120. A tower base 130 that connects the first tower 110 and the second tower 120 is disposed in the The tower base 130 is assembled to the base case 150. The first tower 110 and the second tower 120 may be manufactured integrally.

[0094] Unlike the present embodiment, the first tower 110 and the second tower 120 are mounted on a tower base 13. It can be directly assembled to the base case 150 without the need for a can be manufactured to.

[0095] The base case 150 forms the lower part of the air conditioner 1, and the tower case 140 forms the Form the top of 1.

[0096] The air conditioner 1 draws in ambient air through the base case 150 and filters it in the tower case 140. The tower case 140 is larger than the base case 150. This allows the air to be discharged at a higher position.

[0097] The air conditioner 1 has a columnar shape with a diameter that decreases toward the top. It may be conical or frustoconical in shape.

[0098] Unlike this embodiment, the air conditioner 1 includes all configurations in which two towers are arranged. Unlike the present embodiment, the cross section does not have to be narrower toward the top. No.

The heat dissipation fin 520 has a large surface area. In addition, the heat transferred to the heat dissipation tube 510 can be effectively transferred to the flowing air. can be done.

[0172] The heat dissipation fins 520 change the air flow direction to direct the air to the first outlet 117 or the second outlet 118. The intake port is located at the bottom, and the first outlet port 117 and the second outlet port 12 7 is arranged above. Inside the first tower 110 and the second tower 120, air flows from the bottom The heat dissipation fins 520 form an upward flow from the bottom to the top. Switch the flow from forward to backward.

[0173] The heat dissipation fins 520 are arranged in a first direction at intervals. , the third heat dissipation tube 513, the lower end of the first heat dissipation tube 511, and the second heat dissipation tube 512 The first heat dissipation tube 511 and the second heat dissipation tube 512 are connected to each other except for the lower end. The pitch of the heat dissipation fins 520 is not limited.

[0174] The pitch of the plurality of heat dissipation fins 520 is equal to the pitch of the first heat dissipation tube 511 and the second heat dissipation tube 51 2 and the distance between the fins 520 is preferably smaller than the distance between the fins 520. If the pitch of the fins 520 is too large, the air If the pitch of the heat dissipation fins 520 is too small, the heat exchange efficiency will decrease. This is because the pressure loss increases as the pressure increases.

[0175] The heat dissipation fin 520 has a heat dissipation surface 523 and two heat dissipation surfaces 524 and 525 arranged to face each other. 523 and includes a fin side surface 525 having an area smaller than that of the heat dissipation surface 523. The heat dissipation surface 523 has the largest area in the heat dissipation fin 520. The surface 523 is the main surface of the heat dissipation fin 520 from which heat is dissipated.

The tube hole 521 and the second tube hole 522 are formed to penetrate the heat dissipation surface 523 . The heat dissipation fins 520 are inserted into the first tube holes 521 and the second tube holes 522. The first heat radiation tube 511 and the second heat radiation tube 512 are connected to each other by adhesive or crimping. It can be done.

[0177] The length W22 of the heat dissipation fin 520 is the length of the first heat dissipation tube 511 and the second heat dissipation tube 512. The distance between the first tube hole 521 and the second tube hole 522 can be larger than the distance between the first tube hole 521 and the second tube hole 522. The first tube holes 521 and the second tube holes 522 are spaced apart in the longitudinal direction of the heat dissipation fin 520. The distance between the second tube hole 522 and the heat dissipation fin 520 is shorter than the length W22 of the heat dissipation fin 520. The distance between the first tube hole 521 and the second tube hole 522 is determined based on the heat dissipation function. The width W21 of the heat dissipation fin 520 can be 30% to 50% of the length W22 of the heat dissipation fin 520. It may be 30% to 50% of the length W22 of the heat dissipation fin 520.

[0178] The heat dissipation fins 520 are preferably arranged such that their longitudinal direction is in the front-rear direction. When the 0 is placed in the front-to-back direction, the air moving from the bottom to the top moves from the front to the rear. Since heat is exchanged between the heat sink 520 and the heat dissipation fin 520, the heat exchange area and time are increased. can be done.

[0179] The heat dissipation surface 523 defines a plane that intersects with the first direction in which the first heat dissipation tube 511 extends. The heat dissipation surface 523 preferably defines a surface perpendicular to the first direction.

When forming the heat dissipation fin 520, the heat dissipation surface 523 of the heat dissipation fin 520 forms an angle of about 4 degrees with the ground. It is possible.

[0181] Therefore, the intake air rises inside the tower case and hits each of the heat dissipation fins 52. 0, the heat exchange occurs with the heat dissipation fin 520, and the heat dissipation surface 523 is cut horizontally. Instead, it is supplied to the outlets 117 and 127 .

[0182] More specifically, one end of the heat dissipation fin 520 is connected to the other end of the heat dissipation fin 520 via an outlet port. The heat dissipation fin 520 is disposed close to the outlets 117 and 127, and one end of the heat dissipation fin 520 is connected to the heat dissipation fin 52 Therefore, the air drawn from the bottom to the top When the direction changes horizontally, it changes smoothly, so there is less pressure loss in the air. .

A plurality of nozzles are arranged along the longitudinal direction of the first outlet 117 or the second outlet 127, and each nozzle Air can be discharged uniformly from the discharge ports 117 and 127 in the longitudinal direction.

[0184] The heat dissipation fins 520 may have an inclination of less than 45 degrees with respect to a reference plane perpendicular to the first direction. The heat dissipation fins 520 can be made of a metal material that has excellent heat transfer properties. The material of the heat dissipation fins 520 may be different from the material of the heat dissipation tube 510. The material of the heat sink 520 may include aluminum, and the heat sink 510 may include an insulating material. It is possible.

[0186] Referring to FIGS. 6d and 6e, a protective cover 540 prevents the heater 500 from contacting the outside. The protective cover 540 secures the heater 500 to the case and prevents damage to the heater 500. This limits the heat emitted from the heater 500 from being transferred to the case. Bar 540 allows air flowing inside the case to flow to heater 500 .

The friction reducing protrusion 437 can be formed on either one of the board guider 430. and can protrude horizontally from the space board 410. This explanation will be based on the fact that the starting point 437 is formed on the board guider 430. The above is applicable to the space board 410 on which the friction reducing protrusions 437 are formed. can be done.

[0346] The friction reducing protrusions 437 are formed on the board guider 430 and are opposed to the space board 410.

The width of the friction reduction protrusion 437 in the second direction (vertical direction) is 37 in the first direction and is smaller than the width of the board guider 430. If the width of 437 is too wide, the friction reduction effect cannot be expected, so it is preferable that it be 5 mm or less.

[0349] Therefore, the friction reducing protrusions 437 are in contact with the space board 410 moving in the first direction. However, the friction reduction protrusion 437 is one If only the friction reducing projections 43 are arranged, the movement of the space board 410 becomes uneasy.

Preferably, the friction reducing protrusions 437 are provided in three positions at the top, middle, and bottom of the board guider 430. can be arranged.

[0350] 18 and 22, the airflow converter 400 is spaced apart from the tower case 140. The boards 410 are spaced apart to prevent surface contact between the tower case 140 and the space boards 410. It may further include a roller 412 for stopping the movement.

[0351] The rollers 412 are installed on one of the tower case 140 and the space board 410. In this embodiment, the rollers 412 are provided on the space board 410. The roller 412 can be located at the bottom of the space board 410. The rotation axis of the roller 412 is horizontal. More specifically, the rotation axis of the roller 412 extends in the front-to-rear direction.

[0352] A roller 412 is provided on the rear lower portion of the space board 410, and the roller 412 is The rollers 412 support the weight of the space board 410. While being moved, the roller 412 slides and rubs against the tower case 140. The roller 412 is supported by the guide body 440 of the roller 140. The device can be guided by rule 445.

[0353] Rollers 412 support the space board 410 vertically while it is in the tower case 140. When in motion, the tower case 140 and the space board 410 support the weight of the space board 410. The rollers 412 reduce friction between the space board 410 and the rollers 412. The space board 410 is held stable when the robot 10 is moving.

[0354] In particular, even if the space board 410 is projected in the direction of the blowing space, The rollers 412 are supported by the tower case 140 through the space board 414. 10. Specifically, the roller 412 is spaced apart from the width of the Located at the end farthest from the blowing space 105 side of the width direction of the board 410 It is possible.

[0355] Although not shown in the figure, the airflow converter 400 is connected to the tower case 140 and the space board. 410, and the tower case 140 and the space board 410 are separated from each other. The guide pin may further be included.

[0356] The guide pins are installed on either the tower case 140 or the space board 410. In this embodiment, the guide pins are provided on the space board 410. The guide pins can be located at the bottom of the space board 410. The guide pins are horizontal. The guide pin extends in the front-rear direction.

[0357] The guide pins support the space board 410 in the vertical direction while allowing it to slide out of the tower case 140. When the space board 410 slides out of the tower case 140, the weight of the space board 410 is supported. The guide pin reduces friction between the space board 410. 105。 The width of the blowing space 105 can be located at the end farthest from the blowing space 105. Cut.

[0358] The airflow converter 400 determines whether the air is blown out from the first outlet 117 or the second outlet based on the air blowing direction. The air is discharged forward from the first outlet 117 or the second outlet. As the air passes through the first inner wall 115 or the second inner wall 125, the Coanda effect occurs. The airflow converter 400 is disposed on the first inner wall 115 or the second inner wall 125, and selectively The airflow converter 400 changes the wind direction depending on the projection accuracy. Updrafts can be achieved.

[0359] The method of driving the airflow converter 400 will be described as follows.

[0360] 16 and 17, when the guide motor 420 is operated, the pinion gear 42 3 rotates, and the rack 436 meshed with the pinion gear 423 moves, and the board guider 4 30 is raised and lowered.

[0361] When the board guider 430 is raised, the positions of the first slit 432 and the second slit 434 are also raised. The second slit 434 slides down along the body protrusion 444. As the position of 32 gets higher, the first protrusion 4111 gradually moves to the right, and the space board 410 protrudes through the board slit into the blowing space 105.

[0362] That is, the blowing space 105 is closed by the space board 410 . The air discharged through the blowing space 105 forms an updraft. .

[0363] When the board guider 430 descends, the positions of the first slit 432 and the second slit 434 The second slit 434 slides up along the body protrusion 444. As the position of the space bar 432 becomes lower, the first protrusion 4111 gradually moves to the left, The board 410 is drawn into the tower case 140 through the board slit. The blowing space 105 is opened by the space board 410. The air discharged through the gas space 105 is discharged forward and spreads out to the left and right. It will form wind.

[0364] When the board is in the middle position after the Ida 430 is raised or lowered, the space board 41 0 penetrates the board slit and shields part of the blowing space 105 That is, the blowing space is partially opened by the space board 410. The air discharged through the rowing space 105 is concentrated forward and collected. It will form a paralysis.

[0365] Referring to Figures 14 and 15, the first tower 110 faces the blowing space 105. The second tower 12 includes a first inner wall 115 having a first outlet 117 formed therein. 0 is arranged in the direction of the blowing space 105 and has a second inner side in which a second outlet port is formed. The heater 500 is configured to be connected to at least one of the first inner wall 115 and the second inner wall 125. The heater 500 is disposed so as to be spaced apart from at least one of the inner surfaces. A space through which air flows is formed between the heater 500 and the heater 115, and air flows through the space. A space through which air flows is formed between the heater 50 and the second inner surface, and air flows through the space. The air flows between the heater 50 and the inner surface, forming a wall of air. The heat emitted from the first inner wall 115 and the second inner wall 125 cannot be convected. It is shown that the first inner wall 115 and the second inner wall 125 overheat.

[0366] Referring to FIGS. 14 and 15, the first tower 110 is formed outwardly of the first inner wall 115. The second tower 120 includes a first outer wall 114 formed outwardly of a second inner wall 125. The heater 500 includes a second outer wall 124 formed on the first outer wall 114 or the second outer wall 124. The heater 500 is disposed so as to be spaced apart from the inner surface of the first outer wall 114. A space through which air flows is formed between the heater 500 and the second surface, and air flows through the space. A space through which air flows is formed between the inner surface of the outer wall 124, and air flows through the space. Air flows between the heater 500 and the inner surface of the outer wall, forming a wall of air. Therefore, the heat emitted from the heater 500 is convected to the first outer wall 114 and the second outer wall 124. This prevents the first outer wall 114 and the second outer wall 124 from overheating.

[0367] 14 and 15, the heater 500 is positioned closer to the first inner wall 114 than the first outer wall 114. The heater 500 is located closer to the second inner wall 124 than the second outer wall 124. The first inner wall 115 is disposed closer to the first outlet port 117. The air discharged from the second outlet port flows at a high speed onto the second inner wall 125. The first inner wall 115 and the second inner wall 125 have a portion where the air flows at a high speed. Forced convection occurs, allowing the first inner wall 115 and the second inner wall 125 to cool faster. However, the first outer wall 114 and the second outer wall 124 are affected by the indirect Coanda effect. Therefore, the cooling rate of the first outer wall 114 is slower than that of the first inner wall 114. 115, and the cooling rate of the second outer wall 124 is slower than that of the second inner wall 125. , the heater 500 is positioned closer to the first inner wall 115 or the second outer wall 124, Overheating of the case 140 can be prevented more efficiently.

[0368] Referring to FIG. 5, the lower end of the heater 500 is connected to the first tower 110 or the second tower 120. Therefore, the cross-sectional area of ​​the discharge space 103 is The bottom is larger than the top.

[0369] The amount of air flowing from the bottom of the first tower or the second tower 120 is the largest, and the amount of air flowing from the top The air passes through the heater 500 and is discharged into the blowing space 105, and is discharged into the first tower 11. The amount of air flowing from the top end of the second tower 120 is minimal. is disposed closer to the rear lower end than the front lower end of the first tower 110 or the second tower 120, Therefore, the discharge space 103 suitable for the air flow rate can be formed. This prevents pressure loss and improves efficiency.

[0370] The heater 500 has air between the heat dissipation fin 530 and the first outlet 117 or the second outlet. 5, the flow path blocking member 540 is configured to block the flow of the The member 540 is disposed at the lower end of the heater 500 and is connected to the lower end of the first outlet 117 or the second outlet. It extends in the direction of.

[0371] The flow path blocking member 540 is disposed inside the tower case 140. The lower end is positioned above the suction grill.

[0372] The flow path blocking member 540 is inclined so that the rear end is positioned higher than the front end.

[0373] The flow path blocking member 540 extends to the rear end of the first tower 110 or the second tower 120.

[0374] The lower end of the first outlet 117 or the second outlet 118 is disposed above the passage blocking member 540. .

[0375] As shown in FIG. 7, the flow path shielding member 540 is disposed on the left or right side of the front end of the lower horizontal plate 513. Therefore, it can be formed in a semicircular shape. As shown in FIG. 5, the flow path shielding member 540 is formed to have the same width as the lower horizontal plate 513. It can also extend to the rear end.

[0376] The flow path blocking member 540 blocks the air flowing through the first ejection space 103a or the second ejection space 103b. 500. This prevents the air from being directly discharged to the first discharge port 117 or the second discharge port without passing through the heater 500. More specifically, the flow path blocking member 540 is provided at the rear lower end, the left lower end, The right lower end and the inner surface of the first tower 110 are shielded, and the rear lower end, left lower end, right The heater 500 is provided with a shielding member 110 for shielding the lower side end and the inner surface of the second tower 120. The airflow that is discharged directly from the lower left end or the lower right end to the first outlet 117 or the second outlet is blocked. This provides cover and improves efficiency.

[0377] 24 to 26, an air conditioner according to another embodiment of the present invention includes a heater 500. In addition, an air guide that guides the redirected air to the first outlet 117 or the second outlet It may further include an id 160.

[0378] The air guide 160 is configured to change the air flow direction in the discharge space 103 to a horizontal direction. A plurality of air guides 160 may be arranged.

[0379] The air guide 160 redirects the air flowing from the bottom to the top in a horizontal direction. The exhausted air flows to the outlets 117 and 127 .

[0380] When division of the air guide 160 is required, the one arranged inside the first tower 110 is divided into the second tower 110 and the The first air guide 161 is referred to as the air guide 161, and the air guide 161 is referred to as the air guide 2. It is called 162.

[0381] The outer end of the first air guide 161 is coupled to the outer wall of the first tower 110. The inner end of the guide is adjacent to the first heater 501 .

[0382] The front end of the first air guide 161 is close to the first outlet port 117. The front end can be connected to the inner wall near the first outlet port 117. The rear end is spaced apart from the rear end of the first tower 110 .

[0383] In order to guide the air flowing from the lower side to the first outlet port 117, the first air guide 161 is , is formed by a curved surface that is convex from the bottom to the top, and the rear end is positioned lower than the front end.

[0384] The first air guide 161 is divided into a curved surface portion 161f and a flat surface portion 161e.

[0385] The rear end of the flat surface portion 161e of the first air guide 161 is close to the first discharge guide. The planar portion 160e of the guide extends forward, and more particularly, can extend horizontally to the ground. do.

[0386] The curved surface portion 161f of the first air guide has a rear end disposed on the flat surface portion of the first air guide. The curved surface portion 160f of the first air guide extends downward and forward while forming a curved surface. The front end of the curved surface portion 160f of the first air guide is positioned lower than the rear end. The front and rear ends of the first airfoil may be formed at a horizontal distance of 10mm to 20mm from the ground. The horizontal distance from the front end and rear end of the curved surface portion 160f of the guide to the ground is defined as the curvature length. That is, the curvature length of the curved surface of the first air guide can be formed between 10 mm and 20 mm. can.

[0387] The inlet angle a4 at the front end of the curved surface portion 160f of the first air guide can be formed to 10 degrees. The inlet angle a4 is the distance between the vertical line to the ground and the tangent line to the front end of the curved surface portion 160f of the first air guide. It is defined as the angle between

[0388] At least a part of the right end of the first air guide 161 is adjacent to the outside of the heater 500, The remaining part is connected to the inner wall of the first tower 110. The left end of the first air guide 161 is 1 can be attached to or bonded to the outer wall of the tower 110.

[0389] Therefore, the air moving upward along the discharge space 103 passes through the first air guide 161. In other words, the air that passes through the fan unit 300 rises and flows through the first outlet. It flows backwards, guided by Aguide 161.

[0390] The second air guide 162 is bilaterally symmetrical to the first air guide 161 .

[0391] The outer end of the second air guide 162 is coupled to the outer wall of the second tower 120. The inner end of the guide 162 is adjacent to the second heater 502 .

[0392] The front end of the second air guide 162 is close to the second outlet port 127. The front end of the second air guide 62 can be connected to the inner wall near the second outlet port. The rear end of 62 is spaced apart from the rear end of the second tower 120 .

[0393] In order to guide the air flowing from the lower side to the second outlet port 127, the second air guide 162 The rear end of the cover is positioned lower than the front end.

[0394] The second air guide 162 is divided into a curved surface portion 162f and a flat surface portion 162e.

[0395] The rear end of the flat surface portion 162e of the second air guide is close to the second discharge guide. The planar portion of the blade extends forward and, more particularly, may extend horizontally to the ground.

[0396] The curved surface portion 162f of the second air guide has a rear end that is in contact with the front end of the flat surface portion 162e of the second air guide. The curved surface portion 162f of the second air guide extends downward and forward while forming a curved surface. The front end of the curved surface portion 162f of the second air guide is positioned lower than the rear end. The front and rear ends of the curved surface portion 162f are formed at a horizontal distance of 10 mm to 20 mm from the ground. The horizontal distance from the front end and rear end of the curved surface portion 162f of the second air guide to the ground is the curvature length. That is, the curvature length of the curved surface portion 162f of the second air guide is 10 mm to 20 mm. It can be formed between m.

[0397] The inlet angle a4 at the front end of the curved surface portion 162f of the second air guide can be formed at 10 degrees. The inlet angle a4 is the distance between the vertical line to the ground and the tangent line to the front end of the curved surface of the second air guide. Define the angle.

[0398] At least a part of the left end of the second air guide 162 is adjacent to the outside of the second heater 502. The remaining part is connected to the inner wall of the second tower 120. can be attached to or bonded to the outer wall of the second tower 120.

[0399] Therefore, the air moving upward along the discharge space 103 passes through the second air guide 162. In other words, the air that passes through the fan unit 300 rises and flows through the second outlet. It flows backwards, guided by Aguide 162.

[0400] When the air guide 160 is installed, the vertically rising air is redirected horizontally. Therefore, it is possible to discharge air at a uniform flow rate from the air discharge port formed long in the vertical direction. Another advantage is that the air can be discharged horizontally.

[0401] When the inlet angle a4 of the air guide 160 is large or the curvature length is long, the air rising vertically On the other hand, the curvature length of the air guide If the length is too short, it cannot guide the air and horizontal discharge is impossible. When the inlet angle a4 according to the invention is arranged or formed with a curvature length, the air volume increases and noise decreases. It has the effect of

[0402] FIG. 29 is a graph illustrating the difference in effect between the air guide according to the present invention and the prior art. Shows.

[0403] The upper graph in Figure 29 shows the relationship between the fan rotation speed and the air guide inlet angle a4. Although not mentioned in Figure 29, the curved surface of the air guide The rate length can also have an effect. At low fan speeds, the difference is not significant, but When the fan speed increases, the amount of air discharged will differ. When the rotation speed is 2500 RPM, the flow rate discharged from the conventional air purifier is The air is discharged from the air purifier having the air guide of the present invention. It was found that the flow rate was about 14 CMM. When the fan is based on the same RPM, According to the present invention, the air volume can be increased by approximately 4% compared to the prior art.

[0404] The graph at the bottom of Figure 29 shows the airflow caused by the fan's airflow rate depending on the air guide inlet angle (a4). Although not mentioned in Figure 29, the curvature length of the curved surface of the air guide There is no big difference when the airflow rate is low, but When the airflow rate increases, the noise level will change. For example, when the airflow rate is 10.0 cmm, The noise level of the conventional air purifier is about 40.5 dB. It was found that the noise generated by an air purifier with an air guide is about 40 dB. When the same air volume is used as the standard, the noise generated by the present invention is approximately 0.5 dB less than that of the conventional technology. It has the effect of reducing the degree.

[0405] The airflow converter 400 may be located above the heater 500. More specifically, The guide motor 420 can be disposed above the heater 500. generates a driving force, the space board 410 changes the discharged air, and the board guide 430 transmits the driving force of the guide motor 420 to the space board 410. The guide motor 410 and the board guider 430 may be located in front of the heater 500. 20 is disposed above the heater 500. Therefore, the space can be used efficiently. This prevents the guide motor 420 from interfering with the air flow inside the discharge space 103. The motor 420 is a heat-generating component and has the disadvantage of being vulnerable to heat. The guide motor 420 is disposed above the heater 500 and is not disposed on the air flow path. This can prevent the heat of the guide motor 420 from being convected to the guide motor 420.

[0406] The airflow around the heater as viewed from above will be described below with reference to FIG. The air that has passed through the heater device 300 rises from the front of the heater. The air flow direction is switched backward. Most of the air passes through the heater and is heated. The warm air is discharged into the blowing space. A portion of the air is blown through the heater and the outer wall 114. 124. This air forms an air curtain between the heater and the outer wall. This prevents the heat from the heater from convection to the outer wall. This air flows into the space between the heater and the inner wall, forming an air curtain between the heater and the inner wall. To prevent heat from the heater from convection to the inner wall.

[0407] FIG. 27 is an illustrative diagram showing horizontal air currents in the air conditioner according to the first embodiment of the present invention.

[0408] Referring to FIG. 27, when providing horizontal airflow, the first space board 411 is The second space board 412 is hidden inside the second ellipse 120. do.

[0409] The air discharged from the first outlet 117 and the air discharged from the second outlet 127 flows through the blowing space 1 05 and can flow forward through the front stages 112, 122.

[0410] And the air behind the blowing space 105 is After being guided inward, it can flow forward.

[0411] In addition, the air around the first tower 110 flows forward along the first outer wall 114. The air around the second tower 120 can flow forward along the second outer wall 124. can be done.

[0412] The first outlet 117 and the second outlet 127 are formed to extend vertically and are symmetrical. Therefore, the air flowing from the upper side of the first outlet 117 and the second outlet 127 and the air flowing from the lower side This allows the air flowing from the vent to be more uniform.

[0413] In addition, the air discharged from the first discharge port and the second discharge port is blown into the blowing space 105. By merging the airflow, the directness of the discharged air is improved, allowing the air to flow further. It is possible.

[0414] FIG. 28 is an illustrative diagram showing an ascending air current in the air conditioner according to the first embodiment of the present invention.

[0415] Referring to FIG. 28, when providing an updraft, the first space board 411 and the second space board 412 are The baseboard 412 is projected into the blowing space 105, and the blowing space 1 Block the front of 05.

[0416] The first space board 411 and the second space board 412 form a blowing space. Since the front of the outlet 117, 127 is blocked, the air discharged from the outlet 117, 127 is directed to the first space. The first space board 411 and the second space board 412 rise along the rear surface of the blowing space. The liquid is discharged onto the top of the container 105 .

[0417] By forming an updraft in the air conditioner 1, the discharged air is prevented from flowing directly to the user. When circulating the indoor air, the air conditioner 1 is raised. It can be activated by airflow.

[0418] For example, when using an air conditioner and an air conditioner at the same time, the air conditioner 1 operates with an updraft. This can promote indoor air convection, allowing for faster cooling or heating of the indoor air. It is possible.
