DETAILED DESCRIPTION OF THE INVENTION

[0009] An air conditioner according to an embodiment of the present invention will now be described with reference to the drawings. The air conditioner may be, for example, a spot cooler or an air purifier. In the drawings, the same or corresponding parts are designated by the same reference numerals, and description thereof will not be repeated. [Embodiment 1]

[0010] 1 to 7, a first embodiment of an air conditioner 100 according to the present invention will be described. In FIGS. 1 to 7, the right side of the air conditioner 100 is defined as the X-axis direction, the rear side of the air conditioner 100 as the Y-axis direction, and the upper side of the air conditioner 100 as the Z-axis direction. FIG. 1 is a perspective view of the air conditioner 100 according to the first embodiment, viewed from above and rear. FIG. 2 is a development view of the air conditioner 100 shown in FIG. 1 cut open from the central longitudinal section L. FIG. 3 is a view showing a cross section III-III of the air conditioner 100 shown in FIG. 1. FIG. 4 is a view showing a cross section IV-IV of the air conditioner 100 shown in FIG. 1. FIG. 5 is a left-side cross-sectional view showing the flows of air A, W, and M on the left side of the air conditioner 100 shown in FIG. 2. FIG. 6 is a right-side cross-sectional view showing the flows of air A and C on the right side of the air conditioner 100 shown in FIG. 2. FIG. 7 is a left-side cross-sectional view showing the flows of air A, W, and M, which are different from those shown in FIG. 5.

[0011] As shown in FIG. 1, the air conditioner 100 includes a housing 10. The housing 10 has an inlet 12 through which air flows in and an outlet 13 through which air flows out. In FIG. 1, the upper left side of the page is the front side of the housing 10, the lower right side is the rear side of the housing 10, the lower left side is the right side of the housing 10, and the upper right side is the left side of the housing 10. The housing 10 has a cross section L at the center in the left-right direction, i.e., a wall 11 along the central vertical cross section L. The wall 11 divides the air path from the inlet 12 to the outlet 13 into two sections. The wall 11 is not shown in FIGS. 2 and 5 to 7. FIG. 2 is a development view of the housing 10 cut open 90° from the front to the left and right along the central vertical cross section L. In the first embodiment, the housing 10 has two outlets 13. Hereinafter, of the two outlets 13, the outlet 13 located on the front side of the housing 10 may be referred to as outlet 13f, and the outlet 13 located on the rear side of the housing 10 may be referred to as outlet 13r.

[0012] As shown in Fig. 2, housing 10 has first air passage 15, which is one of two divided air passages, and second air passage 25, which is the other of the two divided air passages. In other words, first air passage 15 and second air passage 25 are different air passages. First air passage 15 communicates with air inlet 12 and air outlets 13f and 13r, respectively. Second air passage 25 communicates with air inlet 12 and air outlets 13f and 13r, respectively. In Fig. 2, the closer to the left or right edge of the page, the further forward the position, and the closer to the center in the left-right direction of the page, the further rearward the position.

[0013] A filter may be provided at the inlet 12. Filters 51 and 52 shown in FIG. 2 are for air purification. Filters 51 and 52 are arranged in this order from the rear. Filter 51 is, for example, a HEPA filter 51. Filter 52 is, for example, a deodorizing filter 52.

[0014] The air conditioner 100 is equipped with fans 16 and 26 that draw air into the first air duct 15 and the second air duct 25. The fans 16 and 26 are examples of "suction devices." The fan 16 that draws air into the first air duct 15 and the fan 26 that draws air into the second air duct 25 may be separate fans or may be a single fan. In the example shown in FIG. 2, the fans 16 and 26 are separate. If the fans 16 and 26 are separate, the function of drawing air in and out is improved. If the fans 16 and 26 are a single fan, that is, a double-intake fan (not shown), this is suitable for a small housing 10.

[0015] As shown in FIG. 3, fans 16 and 26 introduce air A into first air passage 15 and second air passage 25, respectively. Air conditioner 100 includes an evaporator 61 of the refrigeration cycle and a condenser 62 of the refrigeration cycle. Evaporator 61 of the refrigeration cycle is also called an evaporator, and cools air A that has flowed into first air passage 15. Hereinafter, air C cooled by evaporator 61 may be referred to as cold air C. Condenser 62 of the refrigeration cycle is also called a condenser, and heats air A that has flowed into second air passage 25. Hereinafter, air W heated by condenser 62 may be referred to as warm air W.

[0016] As shown in FIG. 4, the condenser 62 heats air to produce warm air W. The air conditioner 100 includes an evaporator 70 that uses heat of vaporization to cool the warm air W flowing out of the second air duct 25. The evaporator 70 cools and humidifies the warm air by evaporating moisture from the evaporator 70 into the warm air W. The evaporator 61 and the condenser 62 form a refrigeration cycle and are connected (not shown) to allow the refrigerant to move. The air conditioner 100 includes a compressor 63, a pressure reduction unit (not shown), and a dehumidification tank 64 as components necessary for the refrigeration cycle. When the refrigerant moves from the evaporator 61 to the condenser 62, it is compressed by the compressor 63, which inevitably raises the temperature of the refrigerant. Furthermore, when the refrigerant moves from the condenser 62 to the evaporator 61, it is depressurized by the pressure reduction unit (not shown), which inevitably lowers the temperature of the refrigerant. As the air is cooled by the evaporator 61, water vapor appears as water droplets (not shown) from the air C, that is, the cold air C. The dehumidification tank 64 receives the water droplets that appear.

[0017] 4 and 5, air A flowing in from inlet 12 communicating with second air passage 25 by fan 26 is heated in condenser 62 to become warm air W. The warm air W is cooled and humidified by evaporator 70. Therefore, air M flowing out from outlet 13r communicating with second air passage 25 has a lower temperature and higher humidity than the warm air W.

[0018] 4 and 6, air A flowing in from inlet 12 communicating with first air passage 15 by fan 16 is cooled in evaporator 61 to become cool air C, which flows out from outlets 13f and 13r communicating with first air passage 15. Since cooling of air A by evaporator 61 is not essential, the air flowing out from outlets 13f and 13r communicating with first air passage 15 may not be cool air C, but may simply be blown air. Whether it is cool air C or blown air, the air provides a feeling of coolness.

[0019] As explained with reference to Figures 4 to 6, cool air C or blown air is supplied from first air duct 15 through outlet 13f and outlet 13r into the room in which air conditioner 100 is installed. Air M that is cooler than hot air W is supplied from second air duct 25 through outlet 13r into the room in which air conditioner 100 is installed. This makes it possible to suppress the temperature rise of the heat being discharged. In addition, the user can feel cool. Furthermore, since air M supplied from second air duct 25 has been humidified by evaporator 70, it is possible to humidify the room. Furthermore, even if heat from air conditioner 100 is not discharged outdoors, it is possible to suppress the temperature rise of the room in which air conditioner 100 is installed.

[0020] Next, the air conditioner 100 will be described in detail with reference to FIGS.

[0021] 4, the vaporizer 70 is disposed downstream of the condenser 62 in the direction in which the warm air W flows in the second air passage 25. Therefore, the warm air W that reaches the vaporizer 70 is heated to a temperature at which the vaporizer 70 functions efficiently. Therefore, the warm air W is efficiently cooled by the vaporizer 70.

[0022] As shown in FIG. 7 , the vaporizer 70 includes a water supply unit 71 and a humidifying filter 74. The water supply unit 71 includes a humidifying tank 72 and a humidifying tray 73. The humidifying tank 72 supplies water to the humidifying tray 73. The humidifying tray 73 stores the water supplied from the humidifying tank 72. The humidifying filter 74 is immersed in the water stored in the humidifying tank 72 and is exposed to the warm air W flowing out of the second air duct 25. Here, the humidifying filter 74 may be smaller than a configuration that sprays water, such as a mist. Therefore, by including the water supply unit 71 and the humidifying filter 74 in the vaporizer 70, the vaporizer 70 can be made smaller. This ultimately allows the air conditioner 100 to be made smaller overall. The humidifying filter 74 is preferably replaceable.

[0023] Second air passage 25 has third air passage 35 and fourth air passage 45 that branch off from each other. Third air passage 35 and fourth air passage 45 both communicate with outlet 13f and outlet 13r. In the example shown in Fig. 7, third air passage 35 communicates with outlet 13r, and fourth air passage 45 communicates with outlet 13f. Of course, third air passage 35 and fourth air passage 45 may communicate with the same portions of outlet 13f and outlet 13r.

[0024] Evaporator 70 is disposed in third air passage 35. Therefore, air M and air W supplied from second air passage 25 through outlet 13r and outlet 13f are a mixture of air M cooled and humidified by vaporizer 70 from third air passage 35 and air W not cooled or humidified by vaporizer 70 from fourth air passage 45. Therefore, air M and air W supplied from third air passage 35 and fourth air passage 45 in second air passage 25 through outlet 13r and outlet 13f can provide a cool feeling to the user and reduce humidity in the room.

[0025] Housing 10 includes damper 27 that adjusts the ratio of warm air W passing through third air passage 35 and fourth air passage 45. Damper 27 is an example of a "flow rate adjustment mechanism." Damper 27 includes blade plate 28, a pivot shaft 29, and a control device (not shown). Blade plate 28 rotates about pivot shaft 29 to adjust the ratio between the opening area of ​​third air passage 35 and the opening area of ​​fourth air passage 45. The control device controls the rotation of blade plate 28 to adjust the ratio between the opening area of ​​third air passage 35 and the opening area of ​​fourth air passage 45. Therefore, damper 27 adjusts the ratio of warm air W flowing into third air passage 35 and the ratio of warm air W flowing into fourth air passage 45. In other words, damper 27 adjusts the ratio between air M cooled and humidified in vaporizer 70 and warm air W not cooled and humidified in vaporizer 70. Therefore, the damper 27 can adjust the cooling sensation and the humidity in the room.

[0026] 7, housing 10 may have louvers 46 at outlet 13f communicating with fourth air passage 45. Louvers 46 separate the warm air W supplied from fourth air passage 45 through outlet 13f into warm air W supplied from the top surface of housing 10 and warm air W supplied from the front surface of housing 10. The angle of louvers 46 adjusts the ratio of warm air W supplied from the top surface of housing 10 to warm air W supplied from the front surface of housing 10. [Embodiment 2]

[0027] Next, a second embodiment of the air conditioner 100 according to the present invention will be described with reference to Figs. 8 to 12. Fig. 8 is an exploded view of the air conditioner 100 cut open at the central longitudinal section L. Fig. 9 is a view of the transverse section of the air conditioner 100 as seen from above. Fig. 10 is a view of the longitudinal section at the center in the front-to-rear direction of the air conditioner 100 as seen from the front. Fig. 11 is a schematic side view showing the principle of the vaporizer 70 provided in the air conditioner 100, illustrating a state in which the vaporizer 70 is not humidifying. Fig. 12 is a schematic side view showing a state in which the vaporizer 70 of Fig. 11 is humidifying.

[0028] Fig. 8 is a diagram corresponding to Fig. 2 in embodiment 1. As shown in Fig. 8, second air passage 25 in embodiment 2 does not branch like second air passage 25 in embodiment 1, and communicates with outlet 13r. On the other hand, first air passage 15 in embodiment 2 communicates with outlet 13f.

[0029] The vaporizer 70 of the second embodiment is not disposed near the outlet 13r (third air passage 35) as in the vaporizer 70 of the first embodiment. As shown in FIGS. 9 and 10 , the humidifying filter 74 of the vaporizer 70 of the second embodiment is disposed between the condenser 62 and the fan 26 in the second air passage 25. The humidifying tank 72 of the vaporizer 70 of the second embodiment is disposed to the right of the evaporator 61 inside the housing 10. The humidifying filter 74 and the humidifying tank 72 of the second embodiment can be made larger because they effectively utilize the space inside the housing 10. A larger humidifying filter 74 cools and humidifies the warm air W more sufficiently. A larger humidifying tank 72 requires less frequent refilling with water than a smaller one. This reduces the user's effort to refill the humidifying tank 72 with water.

[0030] The humidifying filter 74 is preferably large, and is also preferably of a rotary type. The vaporizing section 70 having the rotary type humidifying filter 74 will be described with reference to FIGS.

[0031] As shown in FIG. 11 , the vaporizer 70 having a rotary humidifying filter 74 includes a humidifying tank 72 and a humidifying tray 73 in addition to the rotary humidifying filter 74. The rotary humidifying filter 74 includes a water-containing portion 75 and a non-water-containing portion 76. The water-containing portion 75 contains water when immersed in water. The non-water-containing portion 76 does not contain water even when immersed in water and is made of, for example, resin. The water-containing portion 75 has a shape consisting of a major arc and a chord when viewed in the direction of the rotation axis 77. The non-water-containing portion 76 has a circular shape surrounding the water-containing portion 75 when viewed in the direction of the rotation axis 77. When the chord of the shape of the water-containing portion 75 is approximately horizontal below the rotation axis 77, the chord is located above the water surface in the humidifying tray 73. That is, FIG. 11 shows a state in which only the non-water-containing portion 76 is immersed in water in the humidifying tray 73, i.e., a state in which the rotary filter does not contain water. When the rotary humidifying filter 74 shown in FIG. 11 rotates around the rotation axis 77, for example as shown in FIG. 12, the major arc of the shape of the water-retaining portion 75 is located below the water surface in the humidifying tray 73. FIG. 12 shows a state in which the water-retaining portion 75 is immersed in the water in the humidifying tray 73, that is, a state in which the rotary humidifying filter 74 contains water. When the rotary humidifying filter 74 is not in use, the humidifying function of the air conditioner 100 is stopped by putting the humidifying filter 74 in the state shown in FIG. 11. On the other hand, when the rotary humidifying filter 74 is used, the humidifying function of the air conditioner 100 is exerted by putting the humidifying filter 74 in the state shown in FIG. 12, or in a state in which the humidifying filter 74 alternates between FIGS. 11 and 12 (a state in which the rotary humidifying filter 74 continues to rotate around the rotation axis 77). 11 and 12 show the water-retaining portion 75 as having a shape consisting of a major arc and a chord, but as long as the rotary humidifying filter 74 can switch between stopping and starting the humidification function, the water-retaining portion 75 may have a shape consisting of a minor arc and a chord, or another shape. By allowing the rotary humidifying filter 74 to switch between stopping and starting the humidification function, water is not used in the humidifying tank 72 when humidification is not required. In other words, the loss of water in the humidifying tank 72 is suppressed, thereby reducing the user's effort to refill the humidifying tank 72 with water.

[0032] In this way, in the air conditioner 100 of the second embodiment, the evaporating section 70 has a large humidifying filter 74, so the warm air W is efficiently cooled by the evaporating section 70. In other words, the temperature rise of the emitted heat can be suppressed. In addition, the user can feel cool.

[0033] [Embodiment 3] An air conditioner 100 according to a third embodiment of the present invention will be described with reference to Fig. 13. Fig. 13 is a longitudinal cross-sectional view taken from the front at the center in the front-to-rear direction of the air conditioner 100 according to the third embodiment. In the air conditioner 100 according to the first embodiment, the vaporizer 70 is arranged downstream of the condenser 62 in the direction in which the air A flows in the second air passage 25, whereas in the air conditioner 100 according to the third embodiment, the vaporizer 170 is arranged upstream of the condenser 62 in the direction in which the air A flows in the second air passage 25.

[0034] As shown in FIG. 13, air conditioner 100 includes evaporator 170 that cools air A flowing into second air passage 25 by heat of evaporation, and tray 173.

[0035] The tray 173 stores the water generated by the evaporator 61. More specifically, when the air is cooled by the evaporator 61, water vapor appears as water droplets (not shown) from the air C, that is, the cool air C. The tray 173 receives the water droplets.

[0036] The evaporation unit 170 has a humidifying filter 74. A portion of the humidifying filter 74 is disposed in a tray 173. A portion of the humidifying filter 74 is immersed in water stored in the tray 173. The evaporation unit 170 cools and humidifies the air A by evaporating the moisture in the evaporation unit 170 into the air M.

[0037] Humidifying filter 74 of evaporation section 170 of the third embodiment is disposed upstream of condenser 62 in second air passage 25.

[0038] As a result, air A flowing in from inlet 12, which communicates with second air passage 25, by fan 26 is cooled and humidified by evaporator 170. Air A is heated in condenser 62. Air M, which is at a lower temperature than the warm air that has not been cooled and humidified by the evaporator, is supplied from second air passage 25 into the room in which air conditioner 100 is installed.

[0039] In addition, air flowing in from inlet 12 communicating with first air passage 15 by fan 16 is cooled in evaporator 61 to become cool air C, and flows out from outlets 13f and 13r communicating with first air passage 15.

[0040] According to the air conditioner 100 of the third embodiment of the present invention, cool air C is supplied from the first air duct 15 through the outlets 13f and 13r into the room in which the air conditioner 100 is installed. Air M that is cooler than the warm air is supplied from the second air duct 25 through the outlet 13r into the room in which the air conditioner 100 is installed. This makes it possible to suppress a rise in the temperature of the heat being discharged. This also allows the user to feel cool. Furthermore, it is possible to suppress a rise in the temperature of the room in which the air conditioner 100 is installed without discharging heat from the air conditioner 100 outdoors.

[0041] Furthermore, the tray 173 stores the water generated by the evaporator 61. As a result, the water generated by the evaporator 61 can be used, and the humidification tank 72 does not need to be provided.

[0042] [Embodiment 4] An air conditioner 100 according to a fourth embodiment of the present invention will be described with reference to Fig. 14. Fig. 14 is a view of a longitudinal section at the center in the front-to-rear direction of the air conditioner 100 according to the fourth embodiment, viewed from the front. In the air conditioner 100 according to the third embodiment, the condenser 62 is arranged outside the tray 173, whereas in the air conditioner 100 according to the fourth embodiment, a portion of the condenser 62 is arranged inside the tray 173.

[0043] 14, a portion of the condenser 62 is disposed in a tray 173. As a result, the condenser 62 is cooled by the water in the tray 173.

[0044] [Embodiment 5] An air conditioner 100 according to a fifth embodiment of the present invention will be described with reference to Fig. 15 and Fig. 16. Fig. 15 and Fig. 16 are longitudinal cross-sectional views of the air conditioner 100 according to the fifth embodiment at the center in the front-to-rear direction, viewed from the front. In detail, Fig. 15 is a diagram showing a state in which the vaporizer 170 is humidifying. On the other hand, Fig. 16 is a diagram showing a state in which the vaporizer 170 is not humidifying. In the air conditioner 100 according to the third embodiment, the tray 173 continues to store water, whereas in the air conditioner 100 according to the fifth embodiment, the tray 273 has a discharge mechanism 274 that can discharge water from the tray 273.

[0045] As shown in Figures 15 and 16, the air conditioner 100 includes a tray 273. The tray 273 has a discharge mechanism 274 that can discharge water from within the tray 273. The discharge mechanism 274 has a valve 274a, a control device (not shown), and a discharge tank 275. The discharge mechanism 274 stores water in the tray 273 by closing the valve 274a. On the other hand, the discharge mechanism 274 discharges water from within the tray 273 to the discharge tank 275 by opening the valve 274a.

[0046] When the air conditioner 100 according to the fifth embodiment is used as a dryer, the exhaust mechanism 274 opens the valve 274a. As a result, the air M is not cooled or humidified by the evaporation section 170, and is supplied from the second air passage 25 in a dry state.

[0047] [Embodiment 6] An air conditioner 100 according to embodiment 6 of the present invention will be described with reference to Fig. 17. Fig. 17 is a longitudinal cross-sectional view taken from the front at the center in the front-to-rear direction of the air conditioner 100 according to embodiment 6. While the air conditioner 100 according to embodiment 3 does not include a humidification tank, the air conditioner 100 according to embodiment 6 includes a humidification tank 376.

[0048] As shown in Fig. 17, the air conditioner 100 includes a humidifying tank 376. The humidifying tank 376 supplies water to the tray 173. As a result, water can be stored in the tray 173 before the water generated by the evaporator 61 accumulates. Therefore, the air A can be cooled immediately after the air conditioner 100 starts operating.

[0049] [Embodiment 7] An air conditioner 100 according to embodiment 7 of the present invention will be described with reference to Fig. 18. Fig. 18 is a vertical cross-sectional view taken from the front at the center in the front-to-rear direction of the air conditioner 100 according to embodiment 7. Whereas the air conditioner 100 according to embodiment 6 is provided with one tray 173, the air conditioner 100 according to embodiment 7 is provided with trays 473 and 474.

[0050] As shown in FIG. 18, the air conditioner 100 includes a tray 473 and a tray 474.

[0051] Tray 474 stores water produced by evaporator 61. More specifically, when air is cooled by evaporator 61, water vapor appears as water droplets (not shown) from air C, that is, cool air C. Tray 474 receives the water droplets.

[0052] The humidification tank 376 supplies water to the tray 473 .

[0053] Evaporation unit 170 has humidifying filter 74. A portion of humidifying filter 74 is disposed in tray 473. A portion of humidifying filter 74 is immersed in water stored in tray 473. Evaporation unit 170 cools and humidifies air A by evaporating moisture in evaporation unit 170 into air A.

[0054] As shown in Fig. 18, the air conditioner 100 is equipped with a humidification tank 376. The humidification tank 376 supplies water to a tray 473. As a result, water can be stored in the tray 473. Therefore, the air A can be cooled immediately after the air conditioner 100 starts operating.

[0055] The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above embodiments and can be embodied in various forms without departing from the spirit of the present invention. The drawings mainly show each component in a schematic manner to facilitate understanding, and the thickness, length, number, spacing, etc. of each component shown in the drawings may differ from the actual ones due to the convenience of creating the drawings. Furthermore, the speed, material, shape, dimensions, etc. of each component shown in the above embodiments are merely examples and are not particularly limited, and various modifications are possible within a range that does not substantially deviate from the configuration of the present invention.

[0056] In the first embodiment, the third air passage 35 and the fourth air passage 45 that branch off from the second air passage 25 have been described. However, the configuration of the first air passage 15, which corresponds to the third air passage 35 and the fourth air passage 45, has not been described. Of course, as shown in FIG. 6 , the first air passage 15 may also have two air passages 83 and 84 that branch off from each other. The two air passages 83 and 84 that branch off from the first air passage 15 communicate with outlets 13r and 13f, respectively. Furthermore, the vaporizer 70 may be disposed in the rear air passage 83 of the two air passages 83 and 84 that branch off from each other in the first air passage 15. Furthermore, a damper 87 that corresponds to the damper 27 disposed in the second air passage 25 may also be disposed in the first air passage 15. The damper 87 of the first air passage 15 adjusts the proportion of air C that flows into each of the two air passages 83 and 84 that branch off from each other in the first air passage 15. Damper 27 arranged in second air passage 25 and damper 87 arranged in first air passage 15 may rotate in the same manner, or may rotate independently of each other.

[0057] It has been explained that in first air passage 15, air A is cooled in evaporator 61, causing water vapor to appear as water droplets from cold air C and be received in dehumidification tank 64. That is, in first air passage 15, air A is cooled in evaporator 61, causing cold air C to be dehumidified. If warm air W is humidified by evaporation section 70 in second air passage 25 by the amount dehumidified in first air passage 15, the humidity in the room can be maintained constant.

[0058] When air conditioner 100 of embodiment 1 is used as a dryer, blades 28 of damper 27 shown in Fig. 7 may be rotated (not shown) to a position that blocks third air passage 35. When third air passage 35 is blocked, warm air W is not cooled or humidified by evaporator 70 arranged in third air passage 35, and is supplied in a dry state from fourth air passage 45 through outlet 13f.

[0059] In the embodiment, one air inlet 12 has been described as communicating with the first air passage 15 and the second air passage 25. Specifically, the right half of one air inlet 12 communicates with the first air passage 15, and the left half of one air inlet 12 communicates with the second air passage 25. This allows only one air purifying filter 51 and one filter 52 to be disposed at the air inlet 12. Of course, the air conditioner 100 may have two air inlets, one of which communicates with the first air passage 15 and the other of which communicates with the second air passage 25. In this case, for example, two filters 51 and two filters 52 are disposed in the air conditioner 100.

[0060] In the air conditioners 100 according to the third to seventh embodiments, the vaporizing section 170 has the humidifying filter 74, but this is not limiting. The vaporizing section 170 may have a rotary filter. [Industrial Applicability]
