BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner that can easily clean a blower to which, for example, dust, dust, or oil adheres and a peripheral portion thereof.
[0002]
[Prior art]
In general, an air conditioner adjusts room temperature by cooling or warming inhaled air and blowing it out. FIG. 4 shows a schematic cross-sectional view of an example of an air conditioner. A blower 2 (cross flow fan) and a heat exchanger 3 are installed in the device main body 1 of the air conditioner (indoor unit). The blower 2 and the heat exchanger 3 are arranged in an air guide path 7 extending from the suction port 5 to the blowout port 4, and the wind sent from the suction port 5 toward the blowout port 4 by the blower 2 is the front side of the blower 2 ( It is cooled or heated when it passes through the heat exchanger 3 arranged on the upstream side.
[0003]
The air guide path 7 is surrounded by a front casing 6 a and a rear casing 6 b formed in the device main body 1. The rear casing 6b is formed in a curved state on the rear side of the blower 2, and constitutes the rear wall of the air guide path 7 that extends from the front upper suction port 5 to the front lower lower air outlet 4. Below the heat exchanger 3, a drain pan 8 that receives water droplets generated on the surface of the plate-like fins of the heat exchanger 3 is arranged. The drain pan 8 is formed using the front casing 6a.
[0004]
The air outlet 4 is provided with a wind direction adjuster 9 that adjusts the wind blowing direction. The wind direction adjuster 9 is a vertical wind direction adjusting plate 10 that adjusts the vertical direction of the wind direction, and a right and left that adjusts the horizontal direction of the wind direction. And a wind direction adjusting plate 11. Among these, the up / down air direction adjusting plate 10 is supported on the drain pan 8 side, and the left / right air direction adjusting plate 11 is supported on the casing 6 side.
[0005]
The suction port 5 is formed from the upper part to the lower part of the front lid 12 attached to the device main body 1 so as to be freely opened and closed. An air filter 14 is detachably attached to the apparatus body 1 between the suction port 5 and the heat exchanger 3. The air filter 14 adsorbs most of dust, dust, oil, etc. floating in the sucked air. By removing the air filter 14 and cleaning it, the adsorbed dust, dust, oil and the like are removed.
[0006]
Dust, dust, oil or the like that has passed through the mesh of the air filter 14 enters the inside of the device main body 1, and part of the dust adheres to the surfaces of the blower 2, the heat exchanger 3, the casing 6, and the like. This dust, dust, oil, etc. will become larger due to the adhering dust, dust, oil, etc. sent afterwards, and it will become a resistance to blowing, reducing the performance of the air conditioner, and unhealthy air that blows out There is a risk.
[0007]
When the surface of the dust or dust and the casing 6 is dry and does not contain oil, the amount of dust or dust adhering to the casing 6 is small, but the dust or dust is cooled or cooled by the heat exchanger 3. When heated, it often absorbs moisture or contains oil, and the amount of adhesion to the casing 6 also increases.
[0008]
Therefore, it becomes necessary to clean the blower 2 or the air guide path 7. In Japanese Patent Laid-Open No. 2001-324161, as shown in FIG. 5 , by removing or moving the wind direction adjusting tool 101 (wind direction changing device), the air guide path 102 (wind path) is opened and the wind direction adjusting tool 101 is moved. And the air conditioner which enabled the inside of the apparatus main body 103 to be cleaned is disclosed. Japanese Patent Application Laid-Open No. 11-337105 discloses an air conditioner in which dust adhered to the surface of a fin of a heat exchanger is washed away by spraying a cleaning liquid with a drip-proof cover installed. ing.
[0009]
[Problems to be solved by the invention]
However, since the blower is disposed close to the casing at a position recessed from the air outlet, it is difficult for the user to clean the blower and the casing. On the other hand, full-scale cleaning by experts tends to be avoided because it takes time and costs. Therefore, dust, dust, oil or the like tends to remain attached to the blower or casing, and the function of the air conditioner cannot be fully exhibited.
[0010]
An object of this invention is to provide the air conditioner which can maintain a predetermined | prescribed performance and a favorable sanitary condition so that cleaning of an air guide path and an air blower can be performed easily.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention attaches a casing constituting an air guide path in an apparatus main body to the apparatus main body so as to be removable or movable. According to this configuration, by moving the casing to a position where it can be cleaned, it is possible to easily clean the surface of the air guide path that is in a position that is inherently deep and out of reach. Alternatively, the casing can be removed and cleaned.
[0012]
When the casing constitutes the air outlet and the vicinity thereof, the casing can be moved or removed so as to be pulled out from the air outlet. If the casing is slidably attached to the apparatus body, the casing can be easily moved and detached. At this time, if the curved surface portion of the air guide passage is formed of a flexible casing, the casing can be deformed according to the shape of the air guide passage. The casing may be formed of a thin metal plate or the like, but is more preferably formed from a flexible thermoplastic resin.
[0013]
If a blower is provided in the air guide path in the device body and a cleaning means for cleaning the blower is provided, cleaning of the blower can be simplified. If the air guide path is constituted by a casing that is detachably or movably mounted on the apparatus main body, and a cleaning tool as a cleaning means is attached to the casing, cleaning can be performed by bringing the cleaning tool into contact with the blower during cleaning.
[0014]
Specifically, the cleaning tool attached to the casing is separated from the blower during operation, and the cleaning tool is brought into contact with the blower when the casing is moved to a predetermined position. Alternatively, the cleaning tool may be detachably attached to the casing, and when the cleaning is performed, the casing is detached from the device main body, the cleaning tool is attached, and when the casing is mounted on the device main body again, the cleaning tool may be brought into contact with the blower.
[0015]
When providing a wind direction adjuster that adjusts the direction of the wind blown from the air outlet, if this wind direction adjuster is supported by another member that constitutes the air guide path other than the casing, the wind direction adjuster may interfere with the movement or removal of the casing. do not become.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment and a second embodiment of an air conditioner according to the present invention will be described with reference to the drawings. These air conditioners (indoor units) have substantially the same configuration as the conventional air conditioner shown in FIG. 4 , and the room sucked from the suction port 5 by rotating the blower 2 (cross flow fan) with a motor (not shown). The air passes through the air filter 14 and the heat exchanger 3 in the air guide path 7 and blows out from the outlet 4.
[0017]
1ST EMBODIMENT FIG. 1: is a schematic sectional drawing of the air conditioner of 1st embodiment. In this air conditioner, the rear wall of the air guide path 7 is constituted by a double-structure casing 15, and the inner casing 15 b covering the front side (blower 2 side) surface of the outer casing 15 a can be detachably removed and cleaned. It is what I did. The outer casing 15 a is formed in a vertical direction on the rear side of the blower 2 in the device main body 1 and has a curved shape that guides the wind sent from the front suction port 5 to the front blower port 4.
[0018]
Curved guides (grooves) (not shown) for guiding the inner casing 15b along the surface of the outer casing 15a are formed at portions surrounding both side surfaces of the air guide path 7 of the device body 1. The inner casing 15b is made of a flexible thermoplastic resin plate such as polypropylene, for example, and is slidably guided by the guide of the device main body 1 so as to be drawn out or pushed in. The inner casing 15b is flexible and conforms to the curve of the guide when sliding.
[0019]
The outer casing 15a has a groove 15c into which the upper end of the inner casing 15b is fitted. The upper end of the inner casing 15b is formed in accordance with the shape of the groove 15c, and is closely contacted and locked when fitted into the groove 15c. The lower end 15d of the inner casing 15b has a shape bent rearward so as to engage with the engaging portion 1a of the device main body 1.
[0020]
The engaging portion 1a is such that the front end portion of the lower wall of the device body 1 protrudes to the front side of the outer casing 15a, and the lower end 15d of the inner casing 15b is engaged so as to be pushed into the upper surface side of the engaging portion 1a. . The inner casing 15b is attached to the device main body 1 by pushing the inner casing 15b along the guide, fitting the upper end surface of the inner casing 15b into the groove 15c, and engaging the lower end 15d with the engaging portion 1a.
[0021]
Of the wind direction adjuster 9 arranged at the outlet 4, the vertical wind direction adjusting plate 10 is supported on both side surfaces of the device body 1, and the left and right wind direction adjusting plate 11 is supported by the drain pan 8. When the inner casing 15b is slid and attached or detached from the outlet 4 as in a conventional air conditioner that supports either of them on the casing 6 side, the up / down air direction adjusting plate 10 and the left / right air direction adjusting plate 11 do not get in the way.
[0022]
According to the above configuration, since the inner casing 15b can be slid and detached, the inner casing 15b is removed from the device body 1 by pulling it forward from the outlet 4, and the tap water fork is washed with washing water. After drying, it can be attached to the device body 1 again. Therefore, it is possible to prevent a reduction in the blowing capacity of the blower 2 due to dust, dirt, oil, or the like attached to the casing 15. In addition, the inner casing 15b is easy to clean, and by keeping its surface clean, mold and bacteria are not generated, so clean air can be blown out.
[0023]
In the present embodiment, the inner casing 15b is detachable from the device main body 1. However, the inner casing 15b may be pulled out from the outlet 4 until the surface can be cleaned without being removed from the device main body 1. Alternatively, a sheet may be wound around the surface of the casing and rotated to move the surface to a position where the surface can be cleaned. Or you may comprise casing itself with an endless belt.
[0024]
2ND EMBODIMENT FIG. 2: is a schematic sectional drawing of the use condition of the air conditioner of 2nd embodiment, FIG. 3 is a schematic sectional drawing of the cleaning condition of the air conditioner of 2nd embodiment. In the casing 16 of this air conditioner, the upper end of the inner casing 16b slidably mounted on the front side of the outer casing 16a is protruded above the blower 2, and a brush 17 (cleaning tool) is attached to the protruding portion. . The other structure of this air conditioner is the same structure as the air conditioner of 1st embodiment of FIG.
[0025]
As shown in FIG. 2, during use of the air conditioner, the brush 17 is positioned between the upper portion of the blower 2 and the heat exchanger 2 and the outer casing 16 a so as not to contact the blower 2. As shown in FIG. 3, when cleaning the air conditioner, the brush 17 comes into contact with the blower 2 when the inner casing 16 b is slid downward. By rotating the blower 2 in this contact state, dust, dust, oil or the like attached to the surface of the blower 2 is peeled off from the surface of the blower 2 and blown out from the blower outlet 4. After cleaning the blower 2, the inner casing 16 b is removed from the device main body 1 for cleaning, dried, and then attached to the device main body 1 again. With the above configuration, it is possible to clean the surface of the blower 2 that could not be normally cleaned.
[0026]
As the brush 17, a brush that does not damage the blower 2, such as a roll-like sponge that is rotatably supported by an arm or an innumerable hair implanted therein, is used. The brush 17 in which the hair is implanted has the length of the hair uneven, and even if the length of sliding the inner casing 16b is slightly shifted, the surface of the blower 2 can be cleaned with one of the hair tips. To do.
[0027]
In order to slide the inner casing 16b to a position where the brush 17 hits the blower 2, a mark is put on the inner casing 16b. Thereby, the length to slide can be confirmed. Alternatively, a protrusion is provided on the back surface of the inner casing 16b. As a result, when the inner casing 16b is slid to an appropriate position, the projection stops at a position where the projection is hooked on the device body 1 side.
[0028]
In this embodiment, the inner casing 16b is slid to switch between contact and non-contact between the blower 2 and the brush 17, but the brush 17 may be detachable from the inner casing 16b. In this case, by removing the brush 17 when the air conditioner is used, a protruding portion on which the brush 17 is attached becomes unnecessary, and it does not interfere with the blowing and the suction performance does not deteriorate. At the time of cleaning the air conditioner, the blower 2 is cleaned by removing the inner casing 16b from the device main body 1 and attaching the brush 17, and attaching the inner casing 16b to the device main body 1 again and rotating the blower 2.
[0029]
Further, the brush 17 may be attached to another member instead of being attached to the casing 16b. The member to which the brush 17 is attached may be movable with respect to the device main body 1 but may be fixed to the device main body 1 so that the brush 17 is constantly in contact with the blower 2 even during use of the air conditioner.
[0030]
【The invention's effect】
As is clear from the above description, in the present invention, the casing can be moved to a position where it can be easily cleaned by mounting the casing on the apparatus main body of the air conditioner in a movable manner. Further, by kicking Attach the cleaning tool for cleaning the blower casing can be cleaned blower.
[0031]
As a result, when dust, dust, oil, etc. adhere to the blower and its surroundings that are arranged in a narrow and deep part of the device body, these can be easily cleaned, so that the predetermined performance of the air conditioner and Good hygiene can be maintained.
