Description
Technical Field
The present invention relates to an indoor unit of an air conditioner.
Background
In an indoor unit of an air conditioner, a sensor is provided to detect a state of air sucked in. For example, japanese patent application laid-open No. 2001-91042 discloses a technique in which a sensor is provided in an air passage connecting a suction port formed in the front surface of an indoor unit main body and a blower, and the state of air sucked through the suction port is detected.
Disclosure of Invention
However, the above-described prior art is such that a sensor detects the state of air that has been sucked in from a suction port formed at the front of the indoor unit body. Therefore, there is a problem in that it is difficult to detect the state of air in the living space below the indoor unit.
In addition, a suction port may be formed in an upper surface of the indoor unit main body. In this case, even if a sensor is provided in the air passage connecting the suction port on the upper surface of the indoor unit main body and the blower, it is difficult to detect the state of air in the living space below the indoor unit.
An object of one aspect of the present invention is to provide an indoor unit capable of accurately detecting the state of air in a living space.
In order to solve the above problem, an indoor unit of an air conditioner according to an aspect of the present invention includes: a first suction port formed at least one of an upper surface and a front surface of the indoor unit main body, for sucking air; a second suction inlet formed below the indoor unit body and used as a hole for sucking air; and a sensor that detects an amount of a substance contained in the air sucked through the second suction port.
According to an aspect of the present invention, an indoor unit capable of accurately detecting the state of air in a living space can be realized.

Detailed Description
An embodiment of the present invention will be described below with reference to fig. 1 to 5. 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. Fig. 3 is a perspective view showing an exploded state of the indoor unit 1 shown in fig. 1.
As shown in fig. 1, 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, and a horizontal louver 21. In addition, when the indoor unit main body 10 is viewed from the front (front), the width direction is the left-right direction, the depth direction of the indoor unit main body 10 is the front-rear direction, and the height direction of the indoor unit main body 10 is 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 cross louvers 21 are smaller than the air deflectors 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.
As shown in fig. 2 and 3, the indoor unit main body 10 includes a box main body (not shown), a box cover 11, a blower 12A, a heat exchanger 18, a heat transfer pipe 181, a drain pan (partition wall) 17, and a rear cover 19. The blower 12A, the heat exchanger 18, the drain pan 17, and the like are mounted on the box body, and the box cover 11 is fitted so as to cover the box body. The rear cover 19 is attached to the case cover 11.
(blowing port and suction port)
A blow-out port 10A for blowing out air, which is partially open in the casing cover 11, is formed in the front surface of the indoor unit main body 10. A first suction port 10B, which is partially open in the casing cover 11 and through which air is sucked, 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, is formed in the lower surface of the indoor unit main body 10, with a part of the casing cover 11 being open.
Inside the indoor unit main body 10, 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 are formed.
The blower 12A is disposed in a blower chamber 12 surrounded by the case cover 11 and the drain pan 17. The upper air path and the lower air path are both provided with the blower chamber 12.
The blower 12A sucks air from the first suction port 10B and the second suction port 10C by rotation of a blower fan included in the blower 12A. The blower 12A blows air toward the air outlet 10A by rotation of the blower fan.
The heat exchanger 18 is a component that cools or heats the temperature of the air passing through the inside to a desired temperature. The heat exchanger 18 is connected to a heat transfer pipe 181 through which a refrigerant flows. The heat exchanger 18 performs heat exchange with the refrigerant flowing through the heat transfer pipe 181, thereby cooling or heating the air blown by the blower 12A. The air blown from the blower 12A to the outlet 10A is cooled or heated to a desired temperature by the heat exchanger 18, and then blown out from the outlet 10A.
Accordingly, the air sucked in from the first suction port 10B and the second suction port 10C passes through the blower 12A and the heat exchanger 18 and is blown out from the blow-out port 10A. 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 (sirocco fan) as the blower fan. With such a configuration, the negative pressure generated around the inner hole 17A of the blower chamber 12 can be easily increased by the rotation of the blower fan, and therefore, the air can be easily taken in from the second air inlet 10C. The inner hole 17A will be described later.
The present invention is not limited to this, and the blower 12A may include various blower fans other than the sirocco fan. The air blower 12A may include, for example, a cross flow fan (cross flow fan) as an air blowing fan.
Further, the indoor unit main body 10 is a heat exchanger 18 disposed between the blower 12A and the outlet 10A. However, the arrangement of the heat exchanger 18 is not limited to this, and may be arranged between the first suction port 10B and the blower 12A, 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 by 90mm or more from the front end to the rear side of the lower surface of the indoor unit main body 10.
With such a 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 into the second air inlet 10C. Therefore, the indoor unit 1 can easily suck the air in the room where the indoor unit 1 is installed from the second suction port 10C, as compared with 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 cleaning effect, such as a HEPA Filter (High Efficiency Particulate Air Filter), the Air blown out from the Air outlet 10A becomes clean Air. The HEPA filter passes air sucked by the blower 12A, and captures particles such as dust contained in the air to remove the particles, thereby purifying the air.
Therefore, if clean air blown out from the air outlet 10A is sucked through the second air inlet 10C and air to be detected by the dust sensor 14 and the odor sensor 15 is mixed, there is a possibility that the accuracy of detecting the state of air in the living space is lowered. According to the above configuration, it is possible to effectively prevent the clean air blown out from the air outlet 10A from being mixed with the air sucked in from the second air inlet 10C. Therefore, as compared with the case where the second suction port 10C is provided near the front end of the indoor unit main body 10, the state of the air in the living space can be detected more accurately.
(sensor)
The air sucked through the second suction port 10C is detected by a dust sensor (sensor) 14 and an odor sensor (sensor) 15 included 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 drain pan 17 is a member that receives drain generated in the heat exchanger 18. The drain pan 17 is disposed at a lower portion of the indoor unit main body 10, and is connected to a drain pipe (not shown) for discharging drain water.
Fig. 4 is a perspective view showing an external appearance of a drain pan 17 included in the indoor unit 1 shown in fig. 1, and fig. 5 is a perspective view showing a state in which the sensor casing 16 is removed from the drain pan 17 shown in fig. 4.
As shown in fig. 4 and 5, a sensor case 16 that houses the dust sensor 14 and the odor sensor 15 is disposed in the drain pan 17. The sensor housing 16 is configured to be attached to the drain pan 17 from below.
The dust sensor 14 and the odor sensor 15 are sensors that detect the amount of substances contained in the air drawn in from 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. The odor sensor 15 is a sensor that detects the amount of the odor substance (for example, the concentration of the odor substance) 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 of a human being is actually located below the indoor unit 1. However, since the first suction port 10B is formed at the upper surface of the indoor unit body 10, the air sucked in from the first suction port 10B is mainly defined as the air above the indoor. 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.
In this indoor unit 1, the dust sensor 14 and the odor sensor 15 detect 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 configured to easily suck air in the living space, compared to 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 drawn in from 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, the indoor unit 1 can accurately notify the user of the air condition in the living space. In addition, in the case where the indoor unit 1 has a function of removing dust, odor substances, and the like in the air, the indoor unit 1 can appropriately perform the removal function based on the state of the air in the living space.
The indoor unit 1 may include only the dust sensor 14 or only the odor sensor 15 as a sensor housed in the sensor casing 16. In other words, the indoor unit 1 includes at least one of the dust sensor 14 and the odor sensor 15 as a sensor for detecting the amount of the substance contained in the air sucked through the second suction port 10C. The sensors included in the indoor unit 1 are not limited to the dust sensor 14 and the odor sensor 15, and may be any sensors as long as they detect the amount of substances contained in the air.
(route of sucked air)
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. The drain pan 17 is formed with an internal hole 17A penetrating in the vertical direction (thickness direction), and a wind shielding portion 171 is integrally formed on the upper surface of the drain pan 17 so as to surround the internal hole 17A.
As shown in fig. 5, in the present embodiment, the wind guard 171 is provided so as to cover at least one side (windward side) of the inner hole 17A. By providing the wind shielding portion 171, even in a situation where strong air swirls are present in the blower chamber 12 due to the suction by the blower 12A, the air below the drain pan 17 can be efficiently sucked through the inner hole 17A. As described above, the opening area of the inner hole 17A is preferably larger than the second suction port 10C.
The air sucked from the second suction port 10C flows into the blower fan 12A through the inner hole 17A. The second suction hole 10C is preferably formed in a hole shape having an opening area smaller than that of the inner hole 17A.
When the blower fan included in the blower 12A is rotated, negative pressure is generated around the inner hole 17A of the blower chamber 12, and accordingly, negative pressure is also generated inside the second suction port 10C. Here, when the opening area of the second suction port 10C is smaller than the opening area of the inner hole 17A, the negative pressure generated inside the second suction port 10C is larger than the negative pressure generated around the inner hole 17A. Therefore, the indoor unit main body 10 can efficiently suck air through the second suction port 10C.
The opening shape of the second suction port 10C is substantially rectangular in the present embodiment, but is not limited thereto.
The filter 30 is disposed above the second suction port 10C of the drain pan 17 and between the second suction port 10C and the sensor housing 16. The filter 30 removes coarse dust contained in the air flowing into the dust sensor 14 and the odor sensor 15.
The air sucked in from the second suction port 10C passes through the filter 30, the dust sensor 14, the odor sensor 15, the inner hole 17A, the blower 12A, and the heat exchanger 18, and is blown out from the blow-out port 10A. 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 air sucked from the second suction port 10C passes.
The filter 30 removes coarse dust from the air sucked from the second suction port 10C, thereby reducing the failure rate of the dust sensor 14 and the odor sensor 15.
[ embodiment 2]
Another embodiment of the present invention will be described below with reference to fig. 6. For convenience of description, members having the same functions as those described in the above embodiments are given the same reference numerals, and description thereof will not be repeated.
The indoor unit 2 of an air conditioner of the present embodiment is different from the indoor unit 1 of an air conditioner of embodiment 1 in that: the indoor unit body 10 on which the first suction port 10B is formed is excluded, and the indoor unit body 210 on which the first suction port 210B is formed in the front is included.
A first suction port 210B, through which air is sucked, is formed in an upper front portion of the indoor unit main body 210 with a part of the cover 211 being open. A blow-out port 210A through which air is blown out is formed in a lower front surface of the indoor unit main body 210, with a part of the case cover 211 being open.
With such a configuration, the indoor unit main body 210 does not suck air from above. Therefore, the indoor unit 2 can be installed indoors in a state of being close to or in contact with the ceiling.
In this case, the air sucked in from the first suction port 210B is mainly defined as air near the ceiling of the room. Therefore, even if air detected by the sensors such as the dust sensor 14 and the odor sensor 15 is sucked from the first suction port 210B, the state of the air in the living space cannot be accurately detected. Therefore, the state of the air in the living space can be detected more accurately by detecting the air sucked from the second suction port 10C formed in the lower surface of the indoor unit main body 210, not the air sucked from the first suction port 210B by the sensor.
The positional relationship between the air outlet 210A and the first air inlet 210B is not limited to the above-described positional relationship. The indoor unit main body 210 may have both the air outlet 210A and the first air inlet 210B formed in the front surface. For example, the outlet 210A may be formed in the upper front surface of the indoor unit main body 210, and the first inlet 210B may be formed in the lower front surface.
[ embodiment 3]
Another embodiment of the present invention will be described below with reference to fig. 7. For convenience of description, members having the same functions as those described in the above embodiments are given the same reference numerals, and description thereof will not be repeated.
The indoor unit 3 of an air conditioner of the present embodiment is different from the indoor unit 2 of an air conditioner of embodiment 2 in that: the indoor unit main body 210 is also provided with a first suction port 310B.
A first suction port 310B, through which air is sucked, is formed in an upper surface of the indoor unit main body 310 with a part of the cover 311 opened. A first suction port 210B, through which air is sucked, is formed in an upper front portion of the indoor unit main body 310 with a part of the cover 311 opened. A part of the case cover 311 opens to the lower front surface of the indoor unit main body 310, and an air outlet 210A from which air is blown out is formed.
With such a configuration, the indoor unit main body 310 can suck air from above and from the front. Therefore, the indoor unit main body 310 can suck more air from the first suction ports 210B and 310B per unit time.
In this case, the air sucked in from the first suction ports 210B, 310B is also mainly defined as air near the ceiling of the room. Therefore, even if air detected by the sensors such as the dust sensor 14 and the odor sensor 15 is sucked from the first suction ports 210B and 310B, the state of the air in the living space cannot be accurately detected. Therefore, the state of the air in the living space can be accurately detected by detecting the air sucked through the second suction port 10C formed in the lower surface of the indoor unit main body 310 by the sensor, instead of detecting the air sucked through the first suction ports 210B and 310B by the sensor.
The positional relationship between the air outlet 210A and the first air inlet 210B is not limited to the above-described positional relationship. The indoor unit main body 310 may have both the air outlet 210A and the first air inlet 210B formed in the front surface. For example, the outlet 210A may be formed in the upper front surface of the indoor unit main body 210, and the first inlet 210B may be formed in the lower front surface.
