Detailed Description
[ first embodiment ]
An embodiment of the present invention will be described below with reference to fig. 1 to 8. Fig. 1 is a perspective view showing an external appearance of an indoor unit 1 of an air conditioner according to the present embodiment. Fig. 2 is a longitudinal sectional view of a part of the indoor unit 1 shown in fig. 1.
As shown in fig. 1 and 2, an indoor unit 1 of an air conditioner includes an indoor unit main body 10, a louver 20 disposed on a front surface of the indoor unit main body 10, a horizontal louver 21, a filter 30, and a filter casing (filter support member) 40. The width direction when the indoor unit main body 10 is viewed from the front (front) is defined as the left-right direction, the depth direction of the indoor unit main body 10 is defined as the front-rear direction, and the height direction of the indoor unit main body 10 is defined as the up-down direction.
The air guide plate 20 and the lateral louver 21 are members for guiding the flow of air blown out from the indoor unit main body 10 in a desired direction by changing the arrangement angle with respect to the indoor unit main body 10. The air guide plate 20 and the horizontal louver 21 are independent from each other, and the angle of arrangement with respect to the indoor unit main body 10 is changed. The lateral louver 21 is smaller than the air deflector 20. Therefore, the direction of the air blown out from the indoor unit main body 10 can be finely adjusted by the lateral louvers 21 as compared with the air guide plate 20.
The indoor unit main body 10 includes a casing main body (not shown), a casing cover 11, a blower 12A, a heat exchanger 18, a drain pan (partition wall) 17, and the like. The blower 12A, the heat exchanger 18, the drain pan 17, and the like are attached to the casing main body, and the casing cover 11 is fitted so as to cover the casing main body.
(suction inlet and outlet)
An outlet 10A that is partially open in the casing cover 11 and blows out air is formed in the front surface of the indoor unit main body 10. A first suction port 10B that is partially opened in the casing cover 11 and sucks air is formed in the upper surface of the indoor unit main body 10. A second suction port 10C, which is a hole through which air is sucked and which is a part of the casing cover 11 is opened, is formed in the lower surface of the indoor unit main body 10.
Inside the indoor unit main body 10 are formed: an upper air path through which the air sucked in from the first suction port 10B passes and reaches the air outlet 10A, and a lower air path through which the air sucked in from the second suction port 10C passes and reaches the air outlet 10A.
The blower 12A is disposed in a blower chamber 12 formed by being surrounded by the casing main body, the casing cover 11, and the drain pan 17. The blower chamber 12 is disposed in the upper air path and the lower air path.
The blower 12A sucks air from the first suction port 10B and the second suction port 10C by rotation of a blower fan provided in the blower 12A. The blower 12A blows the sucked air toward the air outlet 10A by the rotation of the blower fan.
The heat exchanger 18 is a member that cools or heats the temperature of the air passing through the inside to a desired temperature. The air blown from the blower 12A to the air outlet 10A is cooled or heated to a desired temperature by the heat exchanger 18, and then blown out from the air outlet 10A.
Accordingly, the air sucked in from the first suction port 10B and the second suction port 10C is blown out from the blow-out port 10A through the blower 12A and the heat exchanger 18. Air guide plate 20 is disposed in front of air outlet 10A, and guides the flow of air blown out from air outlet 10A to a desired direction.
In the present embodiment, the blower 12A preferably includes a sirocco fan as the blower fan. With this configuration, the negative pressure generated around the inner hole 17A of the blower chamber 12 by the rotation of the blower fan can be easily increased, and therefore air can be easily sucked through the second suction port 10C. The inner hole 17A will be described later.
The present invention is not limited to this, and the blower 12A may have various blower fans other than the sirocco fan. The blower 12A may be provided with a cross flow fan as a blower fan, for example.
The distance d1 between the front end of the lower surface of the indoor unit main body 10 and the second suction port 10C is preferably 90mm or more. In other words, the second suction port 10C is preferably formed at a position separated from the front end of the lower surface of the indoor unit main body 10 toward the rear side by 90mm or more.
With this configuration, the distance between the air outlet 10A and the second air inlet 10C is appropriately set. Therefore, the air blown out from the air outlet 10A can be effectively suppressed from being directly sucked from the second suction port 10C. Therefore, in the indoor unit 1, the air in the room in which the indoor unit 1 is installed is more easily sucked through the second suction port 10C than the air blown out from the air outlet 10A.
In the indoor unit 1 of the Air conditioner, when the first intake port 10B includes a Filter (not shown) having a High Air purification effect, such as a HEPA Filter (High Efficiency Air Filter), for example, the Air blown out from the Air outlet 10A becomes purified Air. The HEPA filter passes air sucked by the blower 12A, and captures and removes particles such as dust contained in the air, thereby purifying the air.
Therefore, when the clean air blown out from the air outlet 10A is sucked from the second air inlet 10C and mixed with the air to be detected by the dust sensor 14 and the odor sensor 15, there is a possibility that the accuracy of detecting the state of the air in the living space is lowered. According to the above configuration, mixing of clean air blown out from the air outlet 10A and air sucked in from the second air inlet 10C can be effectively suppressed. Therefore, the state of the air in the living space can be detected more accurately than in the case where the second suction port 10C is provided near the front end of the indoor unit main body 10.
(sensor)
The air sucked through the second suction port 10C is detected by a dust sensor (sensor) 14 and an odor sensor (sensor) 15 provided in the indoor unit 1. The dust sensor 14 and the odor sensor 15 are housed in a sensor case 16 disposed on a drain pan 17.
The dust sensor 14 and the odor sensor 15 are sensors that detect the amount of substances contained in the air sucked through the second suction port 10C. Specifically, the dust sensor 14 is a sensor that detects the amount of dust (for example, the number of particles per unit volume of dust) contained in the air sucked through the second suction port 10C. Further, the odor sensor 15 is a sensor that detects the amount of the odorant (e.g., concentration of the odorant) contained in the air sucked from the second suction port 10C. The sensor casing 16 is disposed on a path through which air sucked from the second suction port 10C formed in the lower surface of the indoor unit main body 10 passes.
The indoor unit 1 is generally disposed above the indoor space. Therefore, in many cases, a living space for a human life is located below the indoor unit 1. However, since the first suction port 10B is formed in the upper surface of the indoor unit main body 10, the air sucked through the first suction port 10B is mainly limited to the air above the indoor space. Therefore, when air detected by the sensors such as the dust sensor 14 and the odor sensor 15 is sucked from the first suction port 10B, the state of the air in the living space cannot be accurately detected.
Here, in the indoor unit 1, the dust sensor 14 and the odor sensor 15 detect the air sucked through the first suction port 10B, and the dust sensor 14 and the odor sensor 15 detect the air sucked through the second suction port 10C formed in the lower surface of the indoor unit main body 10. The second suction port 10C formed in the lower surface of the indoor unit main body 10 is easier to suck air in the living space than the first suction port 10B. Therefore, the dust sensor 14 and the odor sensor 15 that detect the amount of substances contained in the air sucked through the second suction port 10C can accurately detect the state of the air in the living space.
For example, when the indoor unit 1 has a function of detecting the cleanliness of the air in the room and notifying the user of the detected cleanliness, the indoor unit 1 can accurately notify the user of the air condition in the living space. In addition, when the indoor unit 1 has a function of removing dust, odor substances, and the like in the air, the indoor unit 1 can accurately perform the function of removing air in the living space based on the state of the air.
The indoor unit 1 may include only the dust sensor 14 as a sensor housed in the sensor casing 16, or may include only the odor sensor 15 as a sensor housed in the sensor casing 16. The sensor provided in the indoor unit 1 is not limited to the dust sensor 14 and the odor sensor 15, and may be any sensor as long as it detects the amount of a substance contained in the air.
(drainage tray)
Fig. 3 is a perspective view showing an external appearance of the drain pan 17 provided in the indoor unit 1 shown in fig. 1, and fig. 4 is a perspective view showing a state in which the sensor casing 16 is removed from the drain pan 17 shown in fig. 3.
The drain pan 17 is a member that receives the condensed water generated by the heat exchanger 18. As shown in fig. 2, the drain pan 17 is disposed at a lower portion of the indoor unit main body 10 and connected to a drain pipe (not shown) for draining condensed water.
The drain pan 17 also functions as a partition wall that vertically partitions the blower chamber 12 and the space in which the sensor housing 16 is disposed. An inner hole 17A penetrating in the vertical direction (thickness direction) is formed in the drain pan 17, and a wind blocking portion 171 is integrally formed on the upper surface of the drain pan 17 so as to surround the inner hole 17A. In fig. 2, a flow line of the air flow in the blower chamber 12 is indicated by an arrow Y. The air sucked from the second suction port 10C passes through the inner hole 17A and flows into the blower room 12 from the opening 171A.
Fig. 5 is an enlarged perspective view of the damper portion 171 of the drain pan 17 shown in fig. 3. As shown in fig. 2 and 5, the wind shielding portion 171 is provided so as to cover at least the windward side of the inner hole 17A. In the present embodiment, as a more preferable configuration, the damper portion 171 is formed so as to cover the front, upper, and both left and right sides, which become the windward side of the internal hole 17A, and the opening portion 171A is formed at the rear, which becomes the leeward side of the internal hole 17A.
By providing the damper 171, even in a situation where strong air turbulence exists in the blower chamber 12 due to the suction of the blower 12A, air under the drain pan 17 can be efficiently sucked through the inner hole 17A.
In a more preferable configuration, a portion of the damper portion 171 that faces upward from the front is curved. This can reduce the influence of the damper portion 171 indicated by the arrow Y on the original airflow flowing in the blower chamber 12.
As shown in fig. 3 and 4, a sensor case 16 is disposed on the drain pan 17, and the sensor case 16 accommodates the dust sensor 14 and the odor sensor 15. The sensor case 16 is attached to the drain pan 17 from below.
(Filter)
As shown in fig. 2, a filter 30 is provided on the upstream side of the dust sensor 14 and the odor sensor 15 to prevent a trouble caused by inflow of dust such as silk waste. More specifically, filter 30 is located above second suction port 10C and is disposed between second suction port 10C and sensor housing 16, more specifically, between second suction port 10C and dust sensor 14. The filter 30 removes dust contained in the air flowing into the dust sensor 14 and the odor sensor 15.
The air sucked in from the second inlet port 10C is blown out from the outlet port 10A via the filter 30, the dust sensor 14, the odor sensor 15, the inner hole 17A, the damper portion 171, the blower 12A, and the heat exchanger 18. In other words, the dust sensor 14 and the odor sensor 15 are disposed on a path between the inner hole 17A and the second suction port 10C through which the air sucked from the second suction port 10C passes.
By removing dust through the filter 30, it is possible to avoid the malfunction of the dust sensor 14 and the odor sensor 15. In order to more reliably avoid the malfunction of the dust sensor 14 and the odor sensor 15, the filter 30 is preferably a coarse dust filter capable of removing coarse dust (relatively large dust having a predetermined size or more). Specifically, a filter having about 30 cells per inch is preferably used. If a filter with a fine mesh (a large number of cells) is used, the intake of air is inhibited, and substances contained in the air in the living space below the indoor unit 1 are trapped by the filter, and the amount of the substances cannot be accurately detected.
The filter 30 needs to be removed by a user of the air conditioner to be periodically cleaned and maintained. However, the indoor unit 1 is often disposed on a window, and in this case, the curtain rail is located directly below the indoor unit 1. Further, furniture may be disposed directly below the indoor unit 1.
When an installation object such as a curtain rail or furniture is present directly below the indoor unit 1, the operation of attaching and detaching the filter 30 from below the indoor unit 1 is difficult, and the workability of attaching and detaching the filter 30 is reduced. Therefore, in the present embodiment, as described below, the filter 30 is supported by the filter housing 40, and the filter housing 40 is configured to be detachable in the front-rear direction.
(Filter casing)
Fig. 6 is a perspective view showing an external appearance of the casing cover 11 of the indoor unit 1 shown in fig. 1, and fig. 7 is a perspective view showing a state where the filter casing 40 is removed from the casing cover 11 shown in fig. 6. As shown in fig. 6 and 7, an insertion opening 11D for inserting the filter housing 40 is formed in a lower portion of the front surface of the housing cover 11. As shown in fig. 2, a main body side engaging portion 111 for positioning the filter housing 40 in the front-rear direction is provided inside the insertion port 11D of the housing cover 11.
The filter housing 40 supports the filter 30. The filter case 40 is detachably provided to the housing cover 11 through the insertion port 11D from the front of the housing cover 11 in the front-rear direction.
Fig. 8 is a perspective view showing a state where the filter 30 is removed from the filter case 40 shown in fig. 7. As shown in fig. 8, the filter case 40 includes a front wall 41, a rear wall 42, a left wall 43, a right wall 44, a bottom 45, a front rib 46, and a rear rib 47.
The front rib 46 and the rear rib 47 are provided between the front wall 41 and the rear wall 42 so as to extend in the left-right direction and the up-down direction, and the front rib 46 is positioned on the front side of the rear rib 47. The front rib 46 and the rear rib 47 extend over the entire width of the filter case 40 in the left-right direction.
A case hole 45A extending in the left-right direction is formed between the rear side rib 47 and the rear wall portion 42 in the bottom portion 45. The case hole 45A extends over the entire width of the filter case 40 in the left-right direction. The length of the casing hole 45A in the left-right direction may be substantially the same as the length of the second suction port 10C (shown in fig. 1) in the left-right direction, or may be longer than the length of the second suction port 10C in the left-right direction. As shown in fig. 2, the length of the housing hole 45A in the front-rear direction may be substantially the same as the length of the second suction port 10C in the front-rear direction, or may be longer than the length of the second suction port 10C in the front-rear direction.
When the opening area of the housing hole 45A is larger than the opening area of the second suction port 10C, even if there is some error in the attachment position of the filter housing 40, for example, the air sucked from the second suction port 10C easily reaches the filter 30 through the housing hole 45A. Therefore, the opening area of the casing hole 45A is preferably larger than the opening area of the second suction port 10C.
The filter 30 is accommodated on the rear end side of the filter case 40, more specifically, between the rear rib 47 and the rear wall 42 and between the left wall 43 and the right wall 44. Therefore, the filter 30 housed in the filter case 40 is positioned above the case hole 45A. The filter 30 is fixed by claws 432 and 442 provided at the upper edge portions of the left wall portion 43 and the right wall portion 44, respectively. The rear wall portion 42 is cut from above in the vicinity of the center in the left-right direction, and the extending portion 421 is provided so as to extend rearward from the cut edge portion.
The front portions of the left wall 43 and the right wall 44 are provided with member- side engaging portions 431 and 441, respectively, as bilaterally symmetrical stepped portions. As shown in fig. 2, when the filter case 40 is inserted from the insertion opening 11D of the housing cover 11 and attached to the housing cover 11, the component- side engagement portions 431 and 441 of the filter case 40 abut against and engage the main body-side engagement portion 111 of the housing cover 11. Thereby, the filter housing 40 is positioned in the front-rear direction.
At this time, the filter case 40 is placed on the lower surface of the housing cover 11, and is positioned in the vertical direction. Further, the position of the filter case 40 in the left-right direction is positioned by the insertion port 11D.
As shown in fig. 2, in a state where the filter casing 40 is attached to the indoor unit main body 10, the casing hole 45A is positioned above the second suction port 10C. Therefore, the indoor unit 1 is configured such that the flow of air sucked through the second suction port 10C is less likely to be obstructed by the filter casing 40. The filter case 40 is configured such that air sucked from the case hole 45A passes through the filter 30 and flows out toward the sensor case 16 rearward along the protruding portion 421 (shown in fig. 8).
(Effect)
According to the above configuration, the indoor unit 1 detects, by the dust sensor 14 and the odor sensor 15, air sucked through the second suction port 10C formed in the lower surface of the indoor unit main body 10, not air sucked through the first suction port 10B. The second suction port 10C formed in the lower surface of the indoor unit main body 10 is easier to suck air in the living space than the first suction port 10B. Therefore, the dust sensor 14 and the odor sensor 15 that detect the amount of substances contained in the air sucked through the second suction port 10C can accurately detect the state of the air in the living space.
The filter case 40 is detachable from the front of the housing cover 11 in the front-rear direction with respect to the housing cover 11. This enables the filter 30 to be easily attached and detached even when, for example, a curtain rail or furniture is positioned directly below the indoor unit 1. Therefore, the indoor unit 1 of the air conditioner having excellent maintainability can be provided.
Further, since the positioning of the filter housing 40 in the front-rear direction can be easily performed by bringing the member- side engaging portions 431 and 441 into contact with the main body-side engaging portion 111, the filter 30 can be easily disposed at a position overlapping the second suction port 10C. Therefore, the dust contained in the air flowing into the dust sensor 14 and the odor sensor 15 can be more reliably removed.
Further, since the filter casing 40 is placed on the lower surface of the casing cover 11, it is not necessary to strictly adjust the angle of insertion of the filter casing 40 when the filter casing 40 is attached to the indoor unit main body 10. Therefore, the filter housing 40 can be easily attached to the housing cover 11.
(modification example)
In the present embodiment, the first suction port 10B is formed in the upper surface of the indoor unit main body 10, but the present invention is not limited thereto. For example, the first suction port 10B may be formed in the front surface of the indoor unit main body 10. Alternatively, the first suction port 10B may be formed on both the upper surface and the front surface of the indoor unit main body 10. In other words, the first suction port 10B may be formed in at least one of the upper surface and the front surface of the indoor unit main body 10.
