Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner that cools or heats indoor air to harmonize the indoor environment, and more particularly to an indoor unit that is a component of the air conditioner and is installed indoors. .

[0002]

2. Description of the Related Art A conventional air conditioner will be described with reference to the drawings. FIG. 6 is a diagram for explaining the configuration of the indoor unit 100 of the air conditioner, where reference numeral 101 is the housing of the indoor unit, 102 is the air suction surface (having a large number of slits), and 103a, 103b, 103c are All of which are indoor heat exchangers, 104 is an air passage, 105 is a tangential fan (fan), 106 is a stabilizer, 107 is an outlet air passage, 108 is a rear housing (casing) that forms a part of the housing, and 109 is Left and right louvers, 110 are flaps arranged in two steps, and 111 is an outlet. The upper flap is the upper flap 110a, and the lower flap is the lower flap 1.
10b.

The operation of the indoor unit will be described. The air in the room, which is the target space for air conditioning, is sucked by the negative pressure generated in the ventilation passage 104 on the upstream side of the tangential fan 105 due to the rotational driving of the suction surface 1.
02 is sucked into the inside of the housing 101, cooled or heated in the process of passing through the indoor heat exchangers 103a, 103b, 103c, and flows into the ventilation passage 104.

The air that has flowed into the ventilation passage 104 is blown out into the room from the air outlet 111 through the blowout ventilation passage 107 while being guided to the rear housing 108 side by the exhaust action of the tangential fan 105. The air blown out includes a plurality of left and right louvers 109 provided at the air outlet 111, and flaps 110a arranged in two upper and lower stages.
The flow direction is changed by 110b. The flaps 110a and 110b are connected to each other via a link (not shown), and a single motor (driving source) not shown.
When the driving force is transmitted from the link to the link, the link is rotated in parallel while having the same vertical angle.

The exhaust action of the tangential fan 105 will be described. When the tangential fan 105 rotates in the direction of the arrow in the figure, the turbulent flow, which is a circulating flow, is generated inside the tangential fan 105 by the action of the stabilizer 106 arranged in proximity. Due to the action of this vortex, the air in the ventilation passage 104 is drawn inside the tangential fan 105 and is exhausted toward the air outlet 111.

By the way, in the indoor unit 100 of recent air conditioners, in order to achieve cleanliness maintenance of air blown out and energy saving effect, cleaning work inside the indoor unit 100 is facilitated. For example, each indoor heat exchanger 103
The air passing through a, 103b, 103c is introduced through a filter (not shown) installed in the vicinity of the suction surface 102 in advance. As a result, many floating substances floating in the room are taken into the filter, and clean air passes through the indoor heat exchangers 103a, 103b, 103c. However, due to long-term use, each indoor heat exchanger 103a,
Floats, pollen, and mold spores that have not been taken into the filter may adhere to 103b and 103c, and mold may propagate and the spores may be released indoors.

In order to avoid this, the indoor unit 100
The removal work of the suction surface 102 that forms the housing 101 of the indoor heat exchanger 103a is facilitated by the user.
103b and 103c can be cleaned. Further, by cleaning the indoor heat exchangers 103a, 103b, 103c, the heat exchange rate between the air and the refrigerant is improved, and the energy saving effect is also achieved.

[0008]

However, in the indoor unit 100 of the conventional air conditioner described above, the tangential fan 105 provided in a state of being covered by the indoor heat exchangers 103a, 103b, 103c, and the air outlet 111. As a structure for cleaning the wall surface of the blow-out air passage 107 connected to, the practical structure is hardly proposed.

As an example, the left and right louvers 109 and the upper and lower flaps 110 are removed and a hand or a cleaning tool is inserted to insert the tangential fan 105 and the blowout air passage 107.
There is something to clean the wall surface of.

However, even if the left and right louvers 109 and the upper and lower flaps 110 are removed, it is difficult for the user to visually recognize the tangential fan 105 from the air outlet 111 via the air outlet 107 as shown in FIG. In addition, since the width of the blow-out air passage 107 in the up-down direction is small, it is difficult to perform a cleaning operation with a hand in place, and it is not possible to perform accurate cleaning and confirmation of the cleaning state.

The left and right louvers 109 and the flap 110 are also provided.
There is a problem in that the cleaning work is avoided because the cleaning work is complicated because the and are removed and the cleaning work is complicated. In particular, the left and right louvers 109 and the flap 110 are formed to be lightweight and thin, and it is difficult to remove them from the indoor unit 100 provided above the room without damaging them.

At the same time, since the left and right louvers 109 and the flap 110 that have been removed are temporarily left unattended, they may be damaged during cleaning. Furthermore, since the left and right louvers 109 and the flap 110 are formed of a plurality of components, unexpected problems such as loss of each component may occur.

The present invention has been made in view of the above circumstances, and air capable of easily and accurately cleaning the fan and the blowout air passage in the indoor unit, which is one component of the air conditioner. An object is to provide an indoor unit of a harmony machine and an air conditioner.

It is characterized by having a wall surface provided below the insertion line.

With such a structure, the air blown out from the fan and flowing in the blowout air passage enters the gap between the split outlet member and the housing, and flows toward the outlet without swirling. . That is, when there is a step between the wall surface of the split outlet member facing the blowout air passage and the wall portion of the housing, the flow of air may be disturbed by this step, and vibration, abnormal noise, or the like may occur. . Further, when dew condensation occurs, the water drop may enter the gap between the split outlet member and the casing due to the step. In order to attach the divided outlet member such that the wall surface of the divided outlet member is equal to or less than the extrapolation line along the wall portion, for example, the thickness of the divided outlet member may be formed thinner than the member thickness of the housing. , The position of the stepped shape formed for fitting is shifted downward, and the like.

Normally, the flap rotates only about a range of about 90 °, which is between a position which is substantially horizontal and a position where it is substantially vertical about the rotation axis for changing the blowing direction. The substantially horizontal position of the flap here means a state in which the flap closes the air outlet, and includes a state in which the surface of the flap is slightly inclined to the front side in the air blowing direction. Such a structure is often used when the rotary shaft is located above the flap, and the flap rotates only in the range in which it blows air downward when the flap closes the air outlet. Not set.

With the configuration according to the present invention, the flap further rotates upward from the substantially horizontal position to a position substantially forward (front side) of the rotation shaft. That is, the flap exceeds the normal movable range and rotates to a position separated from the wall surface of the split outlet member. As a result, a space that opens toward the fan that communicates with the blow-out air passage is formed behind the rotation axis of the flap, and a large space that is connected to the blow-out air passage and the fan is formed together with the space that is opened due to the removal of the split air outlet members.

The upper flap is structured so that it cannot rotate further upward from a position that is almost horizontal (including a slight forward inclination) that blocks the air outlet, so the lower flap connected to the upper flap by a link goes further upward. Does not rotate.

By using the clutch according to the present invention between the links, it is possible to temporarily disconnect the rotational force applied to each flap via the links. In this disconnected state, the flap is above the rotating shaft, that is, It is possible to rotate to a position different from the normal movable range. When the clutch is engaged, it operates within the normal range of motion. When there are two or more flaps, it is possible to rotate them in conjunction with one drive source via a link, and even in the case of one flap, a movable range different from the normal movable range is rotated. be able to. Also, the clutch connection is
It is desirable that the connection is made at a fixed position. This is because if the clutch is connected at a position different from the normal position and the normal movable range is operated, it will be damaged. The flap located in front of the rotary shaft forms an open space connected to the fan behind the rotary shaft.

4 is a perspective view showing a fitted state, (d) is a perspective view for explaining the operation of the lever 14a, (e) is a spoiler 14
FIG. 6 is an internal structural diagram of the rear housing 11a. In addition, the left-right direction referred to herein means the left-right direction toward the air blowing direction.

Rear housing 11 into which the spoiler 14 is fitted
On both side surfaces R and L of the recess of a (see (a) and (b)),
A concavo-convex shape is formed, and a hole 14a is formed on the left side surface L
Is formed. (Refer to FIG. 4B) At both ends of the spoiler 14, concave and convex shapes are formed which can be fitted in relative to the concave and convex shapes on both side surfaces R and L of the recess of the rear housing 11a.

When the spoiler 14 is attached to the rear housing 11a, as shown in FIG. 4C, the spoiler 14 formed into a substantially triangular prism shape in accordance with the shape of the rear housing 11a,
The right side surface R is inserted into the rear housing 11a from the end (). The left end of the spoiler 14 is attached to the rear housing 1.
It is pushed in (1) while being slid into the left side surface L of 1a, and is fitted into the rear housing 11a. Further, the lever 14a is slid rightward to fix the spoiler 14 ().

The lever 14a is connected to a protrusion 14b (see FIG. 4 (d)) inside the spoiler 14, and when the lever 14a slides rightward, the protrusion 14b follows the rear protrusion 14b to follow the rear housing. It is inserted into a hole 14c (see FIG. 4B) formed on the left side surface L of the body 11a. As a result, the spoiler 14 separated from the rear housing 11a
However, it is fixed and integrated with the rear housing 11a.

When the spoiler 14 is removed from the rear housing 11a, the lever 14a is slid to the left in FIG. 4 (d) to retract the protrusion 14b from the hole 14c and retract it into the spoiler 14. By pulling the left end side of the spoiler 14 to the front side, the spoiler 14 is removed from the rear housing 11a.

Further, the rear housing 11a is provided with the micro switch 13 (detection means) shown in FIG. 4 (e).
The micro switch 13 detects the presence of the spoiler 14 by pressing the detection portion 13 a against the detection member 13 b formed on the spoiler 14. On the other hand, when the detection unit 13a is not pushed by the detection member 13b, the absence of the spoiler 14 is detected.

The signal output from the micro switch 13 upon detecting the spoiler 14 is the tangential fan 1
5 can be prompted to stop the operation, etc., and works as a safety measure in cleaning the tangential fan 15. That is, when the detection unit 13a of the micro switch 13 does not receive the pressing force from the spoiler 14, the operation of the tangential fan 15 is forcibly stopped even during operation, and the tangential fan 15 is completely stopped. become. Therefore, the spoiler 14 is removed to form a large open space S (see FIG. 3B), and even if the tangential fan 15 is inadvertently put in a hand, the tangential fan 15 rotates. There is no need to carry out cleaning work safely.

By making the spoiler 14 attachable and detachable in this manner, a space S having a space width W connected to the blowout air passage 17 is formed below the tangential fan 15 as shown in FIG. 2B. . This space has a large opening diagonally downward so that the user can easily visually recognize the tangential fan 15, which facilitates cleaning.

The wall surface of the spoiler 14 facing the blowout air passage 17 is shaped so as to be connected to the wall portion of the rear housing 11a substantially continuously. More specifically, the wall surface of the spoiler 14 is located slightly lower than the wall portion of the rear housing 11a. This is to prevent the air flowing through the blow-out air passage 17 from entering the gap that is the dividing point between the spoiler 14 and the rear housing 11a. When there is a step at the split portion between the spoiler 14 and the rear housing 11a, a swirl of air or the like is generated at the step portion, and when the air flowing through the blowout air passage 17 further enters the split portion, an abnormal noise is generated. Vibration may occur. Further, when dew condensation or the like occurs, water may get inside the spoiler 14. In order to solve these problems, the wall surface of the spoiler 14 is mounted at a position slightly lower than the extrapolation line along the wall portion of the rear housing 11a.

Further, in the air conditioner of this embodiment, in order to further expand the opening degree of the space S, the lower flap 22
Is configured to include a mechanism for rotating the rear housing 11a to a position separated from the wall of the rear housing 11a. This will be described with reference to FIG. Conventionally, the lower flap 22 rotates about a rotation shaft 24a within a movable range of about 90 ° indicated by an arrow F. The movable range of 90 ° here is about 1 counterclockwise with respect to the horizontal plane where the surface of the lower flap 22 closes the outlet 18.
It means a rotatable angle between 35 ° to 180 ° and 225 ° to 270 ° in which the air blowing direction is set to be almost directly below.

As shown in the figure, the space width W of the space S is a size that can be obtained when the lower flap 22 has the air blowing direction at the air outlet 18 directed downward.
The lower flap 22 of the present embodiment has a rotation angle F2 at a position above the rotation shaft 24a, in other words, at a position on the left side of the rotation shaft 24a (a lower flap shown by a dotted line) in a drawing different from the normal movable range. It can be rotated. As a result, the space width W of the space S is expanded to the space width W2 in which the thickness of the lower flap 22 and the total dimension α of the mounting portion with the rotating shaft 24a are added.

By the way, as described above, the lower flap 22
Needs to be rotated to a position different from the normal movable range. For example, when manually rotating the flaps 21 and 22, only the lower flap 22 can be rotated to a position separated from the wall portion of the rear housing 11a without any problem. Further, even in the case of an automatic control blowing mechanism in which individual motors (driving sources) are connected to the flaps 21 and 22, the lower flap cannot be rotated to a position separated from the wall portion of the rear housing 11a. It is possible. That is, the lower flap 22
The lower flap 22 can be rotated to a position different from the normal movable range by independently rotating a dedicated motor for rotating the motor in the range of the angle F2 in FIG.

The flaps 21 and 22 for automatic control used in many indoor units are connected to a link using one motor (driving source) to connect the upper flap 21 and the lower flap 22. They are rotated in parallel with each other. In such a case, in order to rotate the lower flap 22 alone to a position different from the normal movable range, the configuration of the clutch shown in FIG. 5 is required as an example.

FIG. 5 is a view for explaining the structure of the clutch 30 for transmitting a rotational force from a motor (not shown) to each flap, and FIG. 4A is a sectional view of the clutch 30.
(B) is a front view of the clutch 30 in the direction of arrow G in (a). In FIG. 5A, reference numeral 31 is a boss member, 3
Reference numeral 1a is a convex portion provided on both sides of the boss member 31, 32 is a crank member, 32a is a recess provided in the crank member 32, 33 is a coil spring, and 11 is a housing 11 into which a clutch is inserted.

The clutch 30 is rotatable by inserting a substantially cylindrical boss member 31 connected to a rotary shaft connected to one motor (not shown) into the side wall of the housing 11 at one end thereof. It is said that Two protrusions 31a are formed near the end of the boss member 31 on both sides of the circumference. The crank member 32 has a substantially cylindrical shape whose center portion is slightly larger than the cylindrical shape of the crank member 31, and is fitted to the outer periphery of the cylindrical crank member 31. The cylindrical shape is a two-step shape, and the coil spring 33 is provided between the stepped portion 31 b formed on the boss member 31 and the two-step shape of the crank member 32.

The coil spring 33 is located on the outer circumference of the boss member 31 which is inserted into the housing 11 and fixed in position.
The crank member 32 is pressed against the side wall of the housing 11. Due to this pressing force, the recess 32a of the crank member 32 is fitted to the projection 31a formed on the boss member 31. By fitting the convex portion 31a and the recess 32a into each other, the rotational force transmitted from the motor is transmitted to the boss 31, and further the rotational force is transmitted to the crank member 32.

The boss member 31 is connected to the upper flap 21 (see FIG. 2), and the link portion 32 of the crank member 32 is provided.
b is connected to the lower flap 22 (see FIG. 2), and the flaps 21 and 22 are interlocked and rotated by the rotation of the boss member 31 and the crank member 32. The operation of each of the flaps 21 and 22 described above is the same as the operation during normal operation of the air conditioner.

Then, when the lower flap 22 is independently rotated to a position different from the normal movable range, the crank member 32 is pushed to the left side in the arrow of FIG. 5A to contract the coil spring 33, and the convex portion 31a. The recess 32a is retracted from the crank member 32, and the crank member 32 is rotated. As a result, the recess 32a fitted in the convex portion 31a becomes the convex portion 31a.
The crank member 3 in this state.
The lower flap 22 is independently rotated by rotating 2 (see FIG. 4B).

As shown in FIG. 4 (b), the recess 32a is disengaged from the projection 31a, and the end disk surface 3 of the crank member 32 is removed.
Since the convex portion 31a of the boss member 31 rides on 2c, the convex portion 31a
After a is disengaged from the recess 32a, it is not necessary to press the crank member 32 to the left side, and the recess 32a and the protrusion 31a are not necessary.
It can be freely rotated within a range of a little less than 90 ° while the fitting with is performed. Therefore, as shown in FIG. 2 (b), the lower flap 22 is moved to a position different from the normal rotation range by rotating the lower flap 22 slightly clockwise (F 2) from the closed state of the air outlet 18 in the figure. It can be avoided from S.

In the indoor unit 1 which constitutes the air conditioner of the present embodiment configured as described above, as shown in FIG. 3B, the spoiler 14 can be easily attached / detached and the space S connected to the tangential fan 15 is formed. Since it is formed, the user can insert the hand or the cleaning tool to clean the tangential fan 15 and the blowout air passage 17.
Further, since the tangential fan 15 has a sufficiently wide space width W2 and the tangential fan 15 is at an angle that allows easy visual observation, cleaning can be performed easily and accurately.

Of course, the present embodiment described above is not limited to these.

As a modified example of this embodiment, the following configuration may be adopted. The indoor unit 1 of the present embodiment has been described as having a structure for attaching / detaching the spoiler 14 and a rotating mechanism for the lower flap, which is different from the normal structure, but may be configured independently. Further, although the micro switch 13 is used to detect the attachment / detachment state of the spoiler 14, the present invention is not limited to this, and a detection means similar to a micro switch may be used, or a slide operation of the lever 14a or the like may be used. It may be detected. In the latter case, the operation stop of the tangential fan 15 can be confirmed before the spoiler 14 is attached or detached, and the safety in the cleaning work is further ensured.

Further, in the vertically installed air conditioner in which the indoor unit and the outdoor unit are integrated, the tangential fan and the air outlet are formed to be long in the vertical direction. That is, even when the horizontal air conditioner described in the present embodiment is a vertical air conditioner, the same configuration can be used, and a fan similar to a tangential fan can be easily cleaned.
