Description

An embodiment of the present invention relates to an indoor unit of an air conditioner.

The indoor unit of the air conditioner is provided with a heat exchanger in the air passage in the main body of the indoor unit, and an air filter is provided on the upstream side of the air passage of the heat exchanger. Then, the indoor unit removes the dust contained in the air sucked into the air passage by the air filter, and guides the purified air to the heat exchanger. If the indoor unit is used for a long period of time, dust will accumulate on the air filter. Therefore, the user needs to remove the air filter from the indoor unit main body at appropriate intervals to remove dust adhering to the surface of the air filter.

Since this work is troublesome and troublesome, the air filter is likely to be left attached from the main body of the indoor unit. Therefore, an indoor unit provided with an air filter cleaning device that automatically removes dust adhering to the surface of the air filter inside the indoor unit body without removing the air filter from the indoor unit body has been considered.

For example, the air filter cleaning device disclosed in Patent Document 1 includes a dust box for accommodating dust removed from the air filter. This dust box has an opening for collecting dust removed from the air filter, a dust receiving portion for accommodating the dust collected from this opening, and a nozzle insertion hole for sucking the dust contained in the dust receiving portion. And a movable lid that closes the opening when sucking dust from the nozzle insertion hole. According to this dust box, by inserting the nozzle of the vacuum cleaner into the nozzle insertion hole, the opening is closed by the movable lid, and the dust in the dust receiving portion can be sucked and removed from the nozzle.

By the way, in this kind of dust box, a collection port for collecting dust removed from the air filter, an accommodating portion for accommodating the dust collected from the collection port, and a suction port for sucking the dust contained in the accommodating portion. It is considered to be equipped with. Then, in the dust box having this configuration, by arranging the suction port for sucking the dust contained in the accommodating portion below the air filter, the suction port is placed at a position off the lower side of the air filter, for example, from the side portion of the dust box. Compared with the configuration provided in the protruding portion, the width dimension in the left-right direction can be suppressed, and the dust box can be made compact, and eventually the entire indoor unit can be made compact.
On the other hand, in this type of dust box, a closing wall that closes the upper part of the suction port in order to improve the airtightness of the portion around the suction port in the state where the suction port is open, that is, in the state where dust in the accommodating portion is sucked. It is considered to provide a part.
Therefore, in the configuration in which the suction port is arranged below the air filter and the closed wall portion is provided, the closed wall portion is present below the air filter. Therefore, the dust removed from the air filter by the air filter cleaning device collects on the upper part of the closed wall portion. Then, it is difficult for the suction force from the suction port to act on the closed wall portion, and therefore, once dust is accumulated on the closed wall portion, it is difficult to suck and remove the dust.
Therefore, when the suction port is provided below the air filter, the dust box may be configured to have an opening port at a position below the air filter and above the suction port. That is, the dust box may have a configuration in which the closed wall portion is removed.
According to this configuration, it is possible to prevent dust from accumulating on the closed wall portion and to prevent dust removed from the air filter from remaining in the dust box.
However, if the closed wall portion is removed, the airtightness of the portion around the suction port in the state of sucking the dust in the accommodating portion is lowered, and it becomes difficult to effectively exert the suction force from the suction port. ..

Therefore, instead of the closed wall portion, an indoor unit of an air conditioner capable of ensuring the airtightness of the portion around the suction port is provided.

The indoor unit of the air conditioner according to the present embodiment includes an air filter that captures dust contained in the air passing through the indoor unit main body, an air filter cleaning device that removes dust adhering to the air filter, and the indoor unit. It is provided with a dust box that is detachably attached to the machine body and stores dust removed from the air filter. The dust box has a collection port for collecting dust removed from the air filter, an accommodating portion for accommodating dust collected from the collection port, a suction port for sucking dust contained in the accommodating portion, and the suction port. The lid member that closes the collection port when sucking dust from the mouth, an open port provided at a position below the air filter and above the suction port, and the suction port in an open state. It is provided with a closing portion that closes between the suction port and the opening port. The left-right length of the dust box is equivalent to the left-right length of the air filter, the collection port is provided along the longitudinal direction of the dust box, and the opening port is the collection port of the collection port. It is located on one end side in the longitudinal direction and is provided separately from the collection port .

The brush unit 22 is located on the surface side of the air filter 14.

As illustrated in FIG. 3, the dust box 23 is a long component along the longitudinal direction of the indoor unit main body 11 and is detachably attached to the indoor unit main body 11. As illustrated in FIG. 4, the dust box 23 includes a case member 31, a cover member 32, a lid member 33, a lock member 34, and the like.

The case member 31 is a member that mainly constitutes the base portion of the dust box 23. In this case, the case member 31 has a length substantially equal to that in the case where the two air filters 14 are arranged along the left-right direction of the indoor unit main body 11. It is a long member. The case member 31 has a part of the accommodating portion 35 illustrated in FIG. 2, in this case, the accommodating recess 31a constituting the rear portion. Further, the case member 31 has shaft holes 31b at both ends. Further, a rib support base portion 31c is provided in the central portion of the accommodating recess 31a of the case member 31. As illustrated in FIG. 2, the rib support base portion 31c has two peaks slightly protruding from the inner surface of the accommodating recess 31a and smooth valleys provided between these peaks. Further, a suction port 36 that opens in a substantially rectangular shape is provided at one end of the case member 31.

The cover member 32 is a member mainly constituting the front side of the dust box 23, and has substantially the same length as the case where two air filters 14 are arranged along the left-right direction of the indoor unit main body 11 like the case member 31. It is a long member with an air filter. The cover member 32 has a part of the accommodating portion 35 illustrated in FIG. 2, in this case, the accommodating wall portion 32a constituting the front portion. Further, the cover member 32 has an extending wall portion 32b that continuously extends upward from the accommodating wall portion 32a.

As illustrated in FIG. 2, the accommodating portion 35 is formed by combining the accommodating recess 31a of the case member 31 and the accommodating wall portion 32a of the cover member 32. Further, a collection port 37 is formed between the accommodating recess 31a of the case member 31 and the accommodating wall portion 32a of the cover member 32. The collection port 37 is an opening for collecting dust removed from the air filter 14 by the air filter cleaning device 20. The collection port 37 is a long rectangular opening along the longitudinal direction of the dust box 23. The storage unit 35 stores and stores dust collected from the collection port 37. The accommodating portion 35 has a box shape along the longitudinal direction of the dust box 23.

Like the case member 31 and the cover member 32, the lid member 33 is a long member along the left-right direction of the indoor unit main body 11. The lid member 33 has an arcuate cross section orthogonal to the longitudinal direction. The lid member 33 is provided with rotating shafts 33a at both ends. The lid member 33 is rotatably provided inside the accommodating portion 35 by inserting the rotating shaft 33a into the shaft hole 31b of the case member 31. The outer surface of the lid member 33 provided inside the accommodating portion 35 is pressed in contact with the inner surface around the recovery port 37 of the accommodating portion 35.

As illustrated in FIG. 5, the lid member 33 is provided with a rib 40 at a central portion in the longitudinal direction on the inner surface side thereof. The rib 40 projects in a plate shape from the inner surface of the lid member 33. Further, the rib 40 has a tapered shape, and its tip portion is formed in an arc shape. As illustrated in FIG. 2, the tip portion of the rib 40 rotatably contacts the rib support base portion 31c of the case member 31. That is, the tip portion of the rib 40 rotatably contacts the valley portion while being sandwiched between the peak portions of the rib support base portion 31c. An intake hole 33b that opens in a rectangular shape is provided at one end of the lid member 33. The lid member 33 has a plurality of, in this case, two intake holes 33b.

A valve portion 50 is integrally provided at the other end of the lid member 33. That is, the valve portion 50 rotates integrally with the lid member 33. The valve portion 50 is provided in a plate shape, and as illustrated in FIG. 6, is urged by a coil spring 51 in a direction of closing the suction port 36. The coil spring 51 is attached to the case member 31 via the fixing member 52. When the lid member 33 is rotated to the position where the collection port 37 is opened, the valve portion 50 is rotated to the position where the suction port 36 is closed. Further, when the lid member 33 is rotated to the position where the collection port 37 is closed, the valve portion 50 is rotated to the position where the suction port 36 is opened. As illustrated in FIG. 7, the valve portion 50 is provided with a convex portion 50a on its outer surface. In this case, the convex portion 50a is a streak extending in the longitudinal direction of the dust box 23.

Two lock members 34 are provided separately on the left and right sides of the dust box 23, and are provided so as to be slidable along the longitudinal direction of the dust box 23. The lock member 34 is a member for locking or unlocking the dust box 23 in a fixed state with respect to the indoor unit main body 11.

When an operation operation such as cooling operation or heating operation is performed by the indoor unit 10 of the air conditioner configured in this way, the air sucked into the indoor unit main body 11 passes through the air filter 14. The dust contained in the air filter 14 is captured by the air filter 14. However, if the indoor unit 10 is used for a long period of time, dust accumulates on the air filter 14 and the ventilation resistance increases. If this is left unattended, the heat exchange efficiency will decrease, the cooling capacity and heating capacity will be affected, and the power consumption will increase.

Therefore, according to the indoor unit 10, the air filter automatic cleaning operation can be executed. The air filter automatic cleaning operation can be periodically executed according to a preset operation mode after the end of various air conditioning operations or after a predetermined period of time has elapsed, and is forced based on a remote control operation by the user. It is also possible to execute it as a target.

According to the air filter automatic cleaning operation, the control device (not shown) that controls the overall operation of the indoor unit 10 inputs a drive signal to the air filter feed mechanism unit 21 of the air filter cleaning device 20 to move the air filter 14. , The dust pushing brush of the brush unit 22 and the dust removing blade 22a are rotated. As a result, the dust adhering to the surface of the air filter 14 is pushed up by the brush bristles of the dust pushing brush and is scraped off by the dust removing blade 22a. As a result, dust is removed from the surface of the air filter 14, falls, is collected through the collection hole 37 of the dust box 23, and is stored in the accommodating portion 35. In this way, while reciprocating the air filter 14, the dust adhering to the air filter 14 is pushed up by the dust pushing brush and scraped off by the dust removing blade 22a.

The dust accumulated in the accommodating portion 35 of the dust box 23 can be sucked and removed while the dust box 23 is attached to the indoor unit main body 11. That is, the nozzle N of the vacuum cleaner is inserted into the suction port 36 with the dust box 23 still attached to the indoor unit main body 11. Then, the valve portion 50 is pushed against the urging force of the coil spring 51 by the tip portion of the nozzle N, the suction port 36 is opened, and the lid member 33 rotates to the position where the collection port 37 is closed. .. As a result, the accommodating portion 35 is closed by the lid member 33, and an air flow path communicating from the intake hole 33b of the lid member 33 to the suction port 36 is established in the accommodating portion 35. When the vacuum cleaner is driven in this state, an air flow from the intake hole 33b toward the suction port 36 is formed in the accommodating portion 35. Due to this air flow, the dust in the accommodating portion 35 is attracted to the suction port 36 side and is sucked into the vacuum cleaner through the nozzle N.

According to the indoor unit 10 of the air conditioner according to the present embodiment, the lid member 33 that opens and closes the recovery port 37 is supported only at both ends thereof by the rotating shaft 33a, and the rotating shaft is not provided at the central portion. .. Therefore, it is not necessary to provide a complicated support structure portion for supporting the rotation shaft of the lid member 33 in the central portion in the accommodating portion 35 for collecting dust. Therefore, even in the central portion of the dust box 23, air easily flows when the dust is sucked from the suction port 36, and the dust in the dust box 23 can be efficiently sucked.

Further, according to the indoor unit 10, a rib 40 is provided at the center of the lid member 33. As a result, the central portion of the lid member 33 that is not pivotally supported can be sufficiently supported. In particular, when the dust is sucked from the suction port 36, the inside of the collecting portion 35 becomes a negative pressure, so that there is a concern that the lid member 33 may drop. According to the indoor unit 10, the rib 40 can prevent the lid member 33 from falling. If the lid member 33 can be prevented from falling, it is possible to suppress a decrease in the airtightness in the collecting portion 35 when the dust is sucked from the suction port 36. Therefore, the dust in the dust box 23 can be efficiently sucked.

Further, according to the configuration not provided with the complicated support structure portion for supporting the rotation shaft of the lid member 33, the mold structure for manufacturing the component parts, particularly the case member 31, can be simplified. Manufacturability can be improved. Further, it is not necessary to assemble a complicated support structure portion, and the assembling property of the dust box 23 can be improved.

Further, according to the indoor unit 10, the lid member 33 is provided inside the accommodating portion 35, and the outer surface of the lid member 33 is pressed in contact with the inner surface of the accommodating portion 35. According to this configuration, the lid member 33 rotates while always in contact with the inner surface of the accommodating portion 35, and therefore, the airtightness when the collection port 37 is closed can be further improved.

Further, the valve portion 50 is provided integrally with the lid member 33. Therefore, it is possible to suppress an increase in the number of parts, and it is possible to easily assemble the dust box 23.
Further, the valve portion 50 is provided with a convex portion 50a on its outer surface. According to this configuration, when the valve portion 50 is pushed by the nozzle N, a gap can be secured between the tip portion of the nozzle N and the outer surface of the valve portion 50. As a result, it is possible to prevent the tip end portion of the nozzle N from coming into close contact with the outer surface of the valve portion 50, and it is possible to prevent the suction force from becoming insufficient.

By the way, as illustrated in FIGS. 8 and 9, according to the dust box 23 in which the suction port 36 is arranged below the air filter 14, the suction port protrudes from a position away from the lower part of the air filter, for example, from the side portion of the dust box. The width dimension in the left-right direction can be suppressed as compared with the configuration provided in the provided portion, and the dust box 23 can be made compact, and by extension, the indoor unit 10 as a whole can be made compact.

On the other hand, for example, in the configuration example of the dust box illustrated in FIG. 10, in order to improve the airtightness of the peripheral portion of the suction port 36 in the state where the suction port 36 is open, that is, in the state where the dust in the accommodating portion 35 is sucked. It is considered to provide a closing wall portion 100 that closes the upper part of the suction port 36.

Therefore, in the configuration in which the suction port 36 is arranged below the air filter 14 and the closing wall portion 100 is provided, the closing wall portion 100 exists below the air filter 14. Therefore, the dust removed from the air filter 14 by the air filter cleaning device 20 collects on the upper part of the closed wall portion 100. Then, it is difficult for the suction force from the suction port 36 to act on the closed wall portion 100, and therefore, once dust is accumulated on the closed wall portion 100, it is difficult to suck and remove the dust. ..

Therefore, as illustrated in FIG. 11, when the suction port 36 is provided below the air filter 14, the dust box 23 is provided with an opening 60 at a position below the air filter 14 and above the suction port 36. It is good to say. That is, the dust box 23 may have a configuration in which the closed wall portion 100 is removed from the configuration exemplified in FIG.

According to this configuration, it is possible to prevent dust from accumulating on the closed wall portion and to prevent dust removed from the air filter 14 from remaining in the dust box 23.

However, if the closed wall portion 100 is removed, the airtightness of the portion around the suction port 36 in the state of sucking the dust in the accommodating portion 35 is lowered, and the suction force from the suction port 36 is effectively applied. Will be difficult.

Therefore, as illustrated in FIGS. 12 to 14, the dust box 23 may be further provided with a closing portion 70. In this case, the closing portion 70 is configured by extending the tip portion of the valve portion 50, and is provided integrally with the valve portion 50. The state illustrated in FIG. 12 is a fully closed state in which the valve portion 50 fully closes the suction port 36. In this fully closed state, the closed portion 70 comes into contact with the upper surface of the front end portion of the suction port 36. In this fully closed state, when dust is removed from the air filter 14 by the air filter cleaning device 20 above the suction port 36, the dust falls and collects on the upper part of the valve portion 50 through the open portion 60. Become.

The state illustrated in FIG. 13 is a state in which the valve portion 50 half-opens the suction port 36, that is, a half-open state in which the valve portion 50 rotates in the middle between the suction port 36 and the opening port 60. In this half-opened state, the closed portion 70 is separated from the upper surface of the front end portion of the suction port 36 and also separated from the lower surface of the front end portion of the opening port 60. In this intermediate state, an air flow path is formed from the lower part of the air filter 14 to the suction port 36 via the opening port 60. Therefore, the suction force from the suction port 36 also acts on the upper part of the valve portion 50, and the dust accumulated in the upper part of the valve portion 50 in the fully closed state described above and the dust collected in the upper part of the valve portion 50 and fall through the open portion 60 in this half open state. Dust can be sucked.

The state illustrated in FIG. 14 is a fully open state in which the valve portion 50 fully opens the suction port 36. In this fully open state, the closing portion 70 abuts on the lower surface of the front end of the opening 60. When the tip end portion of the valve portion 50, that is, the closing portion 70 abuts on the lower surface of the front end portion of the opening port 60, the airtightness of the peripheral portion of the suction port 36 is enhanced. Therefore, the suction force from the suction port 36 effectively acts in the accommodating portion 35, and the dust in the accommodating portion 35 can be efficiently sucked. That is, the closed portion 70 exerts a function of ensuring the airtightness of the portion around the suction port 36 in place of the closed wall portion 100 described above.

The switching between the fully closed state illustrated in FIG. 12, the half-open state exemplified in FIG. 13, and the fully open state exemplified in FIG. 14 adjusts the insertion amount S of the nozzle N into the suction port 36 as illustrated in FIG. It can be switched by doing. That is, when the suction port 36 is not inserted into the suction port 36, the suction port 36 is fully closed, and by inserting the nozzle 36 into the suction port 36, the suction port 36 is in a half-open state, and the nozzle N is further inserted into the suction port 36. When it is inserted all the way, the suction port 36 is fully opened. By repeatedly inserting and removing the nozzle N from the suction port 36, the fully closed state, the half-open state, and the fully open state are repeatedly switched, so that the dust accumulated in the upper part of the valve portion 50 and the dust accumulated in the accommodating portion 35 are further reduced. It can be sucked efficiently.

As described above, even when the suction port 36 is provided below the air filter 14, the dust box 23 is provided with an opening port 60 at a position below the air filter 14 and above the suction port 36, and further, the suction port is provided. By providing a closing portion 70 that closes between the suction port 36 and the opening port 60 in the fully opened state of the 36, the dust is prevented from remaining in the dust box 23, and the dust is sucked. The airtightness of the portion around the suction port 36 can be ensured. Therefore, it is possible to realize a configuration in which the dust collected in the dust box 23 can be easily sucked to the outside while making the dust box 23 and thus the indoor unit 10 compact as a whole.

The present embodiment is not limited to the above-described embodiment, and can be expanded or modified as follows, for example.
For example, as illustrated in FIG. 16, the rib 40 may be configured to have a cylindrical protrusion 40a at its tip. Further, as the shape of the rib 40, various shapes can be adopted as long as the shape does not obstruct the flow of air when the dust is sucked from the suction port 36.

As the shape of the convex portion 50a provided on the valve portion 50, various shapes such as a cross shape can be adopted. Further, a plurality of convex portions 50a may be provided on the outer surface of the valve portion 50.
This embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
