Description

The present invention relates to an air conditioner.

An air conditioner (indoor unit) forms an air passage (air passage) that connects an air inlet and an air outlet in its main body, and a cross-flow fan rotates in this air passage. ready for possible. An air conditioner rotates a cross-flow fan in an air passage to suck indoor air through an air inlet and blow it out from an air outlet.

In order to save energy in such air conditioners, efforts are being made to improve the efficiency of related elements. In recent years, it has also been studied to save energy by increasing the diameter of the cross-flow fan to increase the air volume.

In order to increase the size of the cross-flow fan, it is not possible to simply increase the diameter of the cross-flow fan, and it is necessary to increase the size of other members constituting the blower together with the cross-flow fan. In other words, in order to blow air with a cross-flow fan, it is necessary to have a casing member that surrounds the fan such as the stabilizer and rear guider to form an air passage. performance is affected. Therefore, in order to increase the size of the cross-flow fan, it is necessary to increase the size of the casing member.

However, the size (product size) of the air conditioner is limited due to the installation space, etc., and there is a market need to maintain the current product size. Therefore, it is not possible to increase the size of the casing member as desired, which limits the increase in size of the cross-flow fan.

In recent years, there has been a strong demand for larger windows, and the space above the windows is becoming narrower. Therefore, the dimension in the height direction of the air conditioner tends to be compressed so that it can be installed in such a narrow space above the window.

For example, Patent Literature 1 discloses an air conditioner capable of suppressing deterioration in air blowing performance caused by increasing the diameter of a cross-flow fan. According to this, the rotation axis of the wind direction plate located on the wall surface side where the air conditioner is installed, among the plurality of wind direction plates arranged at the air outlet, is provided closer to the wall surface than the rotation axis of the cross flow fan, When the airflow direction plate is rotated downward, the end portion of the airflow direction plate on the wall surface side moves into the outlet.

Japanese patent publication "JP 2016-38151"

As described above, recent air conditioners tend to be compressed in the height direction. The upper part of the air conditioner must have space for installing the heat exchanger, and the dimensions cannot be shortened. be done. Note that the minimum dimension of the air conditioner in the depth direction is ensured for installation of the heat exchanger.

When the space below the cross-flow fan is restricted, the dimension of the lower part of the rear guider, which is one of the casing members, is shortened, and the lower wall surface (lower diffuser) in the air passage from the cross-flow fan to the outlet is increased. shorter in length. If the lower diffuser is shortened, there will be a difference in length with the upper diffuser (the upper wall surface in the air passage from the cross-flow fan to the outlet), which can secure the length by ensuring the minimum dimension in the depth direction. is formed, and the air blowing performance is degraded.

In the configuration of Patent Document 1 described above, since a plurality of wind direction plates are used, the length of each wind direction plate contributing to the air path length is inevitably short. Therefore, even if such a configuration is adapted to an air conditioner in which the dimension in the height direction is compressed so that the dimension of the lower part of the rear guider is shortened, it is not possible to suppress the deterioration of the air blowing performance as desired.

An object of one aspect of the present invention is to realize an air conditioner that can increase the size of the cross-flow fan without increasing the size of the main body, and can also suppress a decrease in air blowing performance.

In order to solve the above problems, an air conditioner according to an aspect of the present invention provides a main body having an upper suction port and a lower outlet port, and an air passage communicating between the suction port and the outlet port. , a heat exchanger and a cross-flow fan arranged in the air passage, and a stabilizer and a rear guider arranged around the cross-flow fan, on the end side of the outlet and on the main body A wind direction plate is rotatably attached to the end of the back side of the body, and blocks the outlet in the closed state and changes the direction of the wind in the open state, the height dimension of the main body is H, and the cross flow When F is the fan outer diameter of the fan, H/F is less than 2.45, and the boundary portion between the tongue portion of the stabilizer and the flat portion below the tongue portion corresponds to the outlet when viewed in longitudinal section. is positioned closer to the front side of the main body than the end on the back side of the stabilizer, and the linear distance A from the upstream end to the downstream end in the airflow direction of the wind direction plate is the same as the flat portion of the stabilizer. It is characterized by being 80% or more of the linear distance B from the upstream end to the front end of the outlet.

ADVANTAGE OF THE INVENTION According to one aspect of the present invention, it is possible to realize an air conditioner that can increase the size of the cross-flow fan without increasing the size of the main body, and can suppress the deterioration of the air blowing performance.

As shown in FIGS. 2(a) and 2(b), inside the main body 1, a heat exchanger 7, a cross-flow fan 8, a stabilizer 9, a rear guider 10, and the like are arranged. Stabilizer 9 and rear guider 10 constitute a casing of cross-flow fan 8 .

The heat exchanger 7 functions as an evaporator to cool air during cooling operation, and functions as a condenser (radiator) to heat air during heating operation. The heat exchanger 7 and the crossflow fan 8 are arranged in the air passage described above, and the heat exchanger 7 is positioned upstream of the crossflow fan 8 .

The heat exchanger 7 is shaped to surround the front, upper and rear upper halves of the cross flow fan 8 . In the example of FIG. 2, the heat exchangers 7 include a front heat exchanger 7a extending obliquely from the front to the top of the crossflow fan 8, and a rear heat exchanger 7a extending obliquely from the top to the middle of the rear of the crossflow fan 8. and an exchanger 7b.

The cross-flow fan 8 has an impeller 8a driven by a motor (not shown). The cross-flow fan 8 is arranged between the suction-side air passage R1 and the blow-out side air passage R2 in the air passage, sucks air from the suction port 2, and blows the air out to the blow-out port 3.

The stabilizer 9 is arranged on the front surface 1a side of the cross-flow fan 8 and stabilizes the wind produced by the cross-flow fan 8. - 特許庁The stabilizer 9 is provided on the lower side of the heat exchanger 7 and divides the inside of the main body 1 into a suction-side air passage R1 and a blow-out side air passage R2. The suction side air passage R1 is located above the stabilizer 9, and the blowing side air passage R2 is located below the stabilizer 9. As shown in FIG.

The stabilizer 9 has a tongue portion 9a and a flat portion 9b that forms a part of the upper wall surface of the outlet-side air passage R2. The tongue portion 9 a faces the cross flow fan 8 . The plane portion 9b is formed on the lower surface of the stabilizer 9 and corresponds to a part of the upper diffuser that is the upper wall surface of the outlet-side air passage R2.

In the example of FIG. 2, the tongue portion 9a and the flat portion 9b are connected via an arcuate portion 9c. Further, a curved portion 9d convex upward is formed on the downstream side (on the front surface 1a side) of the flat portion 9b, and the downstream side thereof becomes the flat portion 9e again. The flat portion 9e on the downstream side abuts flush with an extension portion 6a extending like a wall toward the inside of the main body 1 from the lower end of the resin panel 6 forming the front surface 1a of the main body 1. It is

In the example of FIG. 2, the flat portion 9b, the curved portion 9d and the flat portion 9e of the stabilizer 9, and the extended portion 6a constitute the upper wall surface of the outlet-side air passage R2. Equivalent to a diffuser.

The rear guider 10 extends downward from behind the cross flow fan 8 . The rear guider 10 and the stabilizer 9 constitute a casing that defines an air passage, and guides the air released from the cross-flow fan 8 to the outlet 3 . The wall surface on the lower side of the outlet-side air passage R2 is formed by the wall surface 10a at the lower portion of the rear guider 10, and this wall surface 10a corresponds to the lower diffuser.

A louver 12 is provided inside the outlet 3 and on the front end side of the outlet 3 . The louver 12 changes the distribution of wind required for an air conditioner. A curved portion 9 d formed on the lower surface of the stabilizer 9 serves as a relief portion for the rotation range of the louver 12 .

Next, the size of each part of the air conditioner 100 will be described. FIG. 3 is a vertical cross-sectional view corresponding to (a) of FIG. 2, showing the dimensions of the main part. As shown in FIG. 3, the air conditioner 100 satisfies the following conditions 1-4.

Condition 1: Assuming that the height dimension of the main body 1 is H and the fan outer diameter of the cross flow fan 8 is F, the relationship between H and F is less than H/F=2.45.

Condition 2: The boundary (arc portion 9c) between the tongue portion 9a and the flat portion 9b of the stabilizer 9 is located closer to the front surface 1a of the main body 1 than the rear end portion 3a of the outlet 3 when viewed in longitudinal section. there is

Condition 3: The linear distance A between the upstream end and the downstream end of the wind direction plate 4 is 80% or more of the linear distance B from the upstream end to the downstream end of the upper diffuser of the outlet air passage R2. is. In other words, the linear distance A is 80% or more of the linear distance B from the upstream end of the flat portion 9b of the stabilizer 9 to the front end of the outlet 3 . Upstream and downstream are upstream and downstream with respect to the wind flow direction.

Condition 4: The linear distance A of the wind direction plate 4 is greater than the fan outer diameter F of the cross flow fan 8 .

Here, the height dimension H of the main body 1 is the maximum value of the distance between the upper surface 1b and the lower surface 1d of the main body 1. As shown in FIG. In the example of FIG. 3, H=250 mm. The straight line distance B is from the upstream end, which is the boundary P1 between the arc-shaped portion 9c and the flat portion 9b of the stabilizer 9, to the blowout edge P2, which is the front-side end of the blowout port 3 and reaches the front surface 1a of the main body 1. is the distance of In the example of FIG. 3, B=143 mm. The linear distance A of the air deflector 4 is the separation distance between the two sides of the air deflector 4 along the longitudinal direction. In the example of FIG. 3, A=141 mm. The fan outer diameter F of the cross-flow fan 8 is the outermost diameter measured at the tip of the outer periphery of the blades of the impeller 8a. In the example of FIG. 3, F=104 mm.

Further, an angle θ formed by a line L1 extending from the plane of the flat portion 9b and a line L2 extending from a line connecting the boundary P1 and the blowing end side P2 is in the range of 0<θ<17°. In the example of FIG. 3, θ=8.22 degrees. This angle .theta. is an angle for producing an air flow in consideration of the Coanda effect, in which air is sent toward the ceiling of the room and air flows from the ceiling to the walls. The straight-line distance B in condition 3 is the numerical value of the upper diffuser with the angle θ in the range of 0<θ<17°, which is within the range where the wind can be blown horizontally and can also generate wind toward the ceiling. .

According to such a configuration, the following effects can be obtained. Condition 1 is a condition where it becomes necessary to shorten the dimension of the lower portion of the main body 1 . In other words, since the height dimension H of the main body 1 is restricted, the dimension of the lower part of the rear guider 10 is shortened, and the length of the lower diffuser matching the diameter dimension of the cross flow fan 8 cannot be secured. The smaller the value of H/F, the closer the outer diameter of the cross flow fan 8 to the height dimension of the main body 1. Assuming that the height dimension H of the main body 1 is the same, the smaller the value, the outer diameter F of the fan. becomes larger.

Condition 2 is a condition indicating that the dimension of the lower portion of the main body 1 is shortened. By shortening the dimension of the lower part of the main body 1, the dimension of the lower part of the rear guider 10 is also shortened, making it impossible to ensure the length of the lower diffuser. The rear end portion 3a of the outlet 3 is the downstream end portion of the lower diffuser, and the downstream end portion of the lower diffuser is the boundary between the tongue portion 9a and the flat portion 9b of the stabilizer 9 (arc portion 9c ), a surging phenomenon (a rustling sound, reverse suction, etc.) tends to occur.

That is, the conditions 1 and 2 are conditions in which the size of the cross flow fan 8 is increased while maintaining the size of the product. If these conditions are only satisfied, the length of the lower diffuser is shortened because the diameter of the cross flow fan 8 is increased, and the air blowing performance is lowered.

Therefore, according to the above configuration, in addition to the conditions 1 and 2, the condition 3 is provided, and the linear distance A between the upstream end and the downstream end of the wind direction plate 4 composed of one sheet is 80% or more of the linear distance B from the side edge to the downstream edge. As a result, even if the lower diffuser that satisfies the conditions 1 and 2 is configured to be short, the wind direction plate 4 having a sufficient length in the wind flow direction compensates for the inconvenience caused by the shortening of the lower diffuser. , it is possible to suppress the deterioration of the air blowing performance.

When the inventor of the present application examined the power consumption at the same air volume by changing the length of the wind direction plate 4 while satisfying the condition 2, the following results were obtained.
・When the length of the wind direction plate 4 was set to 10% of the length of the upper diffuser, the power consumption deteriorated by about 30%.
・When the same length was set to 50%, the power consumption worsened by about 10%.
・When the same length is assumed to be 80%, the power consumption deteriorates by about 3%.
・When the same length is assumed to be 90%, the deterioration of power consumption is about 0 to 1%.

As can be seen from these results, the air blowing performance gradually deteriorates as the length of the wind direction plate 4 functioning as the lower diffuser becomes shorter. If the length of the wind direction plate 4 is less than 80% of the length of the upper diffuser, it becomes extremely bad. Based on these results, condition 3 is set. Satisfying the condition 3 makes it possible to suppress a decrease in air blowing performance even in a configuration in which the dimension of the lower portion of the main body 1 is shortened. Here, more preferably, the straight-line distance A should be 90% or more of the straight-line distance B (condition 3'). Satisfying the condition 3' can reliably suppress the deterioration of the air blowing performance. In particular, even if the lower portion of the rear guider 10 is so short that the lower portion of the main body 1 does not function as a lower diffuser, the lowering of the air blowing performance can be suppressed.

Furthermore, in the first embodiment, as a more preferable configuration, condition 4 is provided in addition to condition 3, and the linear distance A of the wind direction plate 4 is made larger than the fan outer diameter F of the cross flow fan 8. . The amount of air generated by the cross-flow fan 8 depends on the outer diameter F of the cross-flow fan 8, and increases as the outer diameter F increases. Even if the conditions 1, 2, and 3 are satisfied, if the straight-line distance A of the airflow direction plate 4 is smaller than the outer diameter F of the cross-flow fan 8, the air produced by the cross-flow fan 8 will flow into the room. may not be delivered in the desired direction. By satisfying condition 4 including condition 4, the wind direction plate 4 can spread the generated wind in a desired direction in the room.

As described above, in the air conditioner 100 according to Embodiment 1, since the condition 1-4 is satisfied, the size of the cross flow fan can be increased without increasing the size of the main body, and the blowing performance is reduced. can also be suppressed. Moreover, if the cross-flow fan 8 of the same size as the conventional product is used, the size of the product can be reduced by making the main body 1 smaller.

On the other hand, the air conditioner according to Embodiment 1 has a configuration that satisfies only the condition 3 in the conditions 1 and 2 and does not satisfy the condition 4.

Even with such a configuration, by shortening the dimension of the lower portion of the main body 1, it is possible to compensate for the problem caused by the shortening of the length of the lower diffuser, and to suppress the deterioration of the air blowing performance.

Note that it is also possible to adopt a configuration in which only the condition 4 is satisfied among the conditions 1 and 2, and the condition 3 is not satisfied. In such a configuration, the air produced by the cross-flow fan 8 can be delivered in a desired direction in the room in a configuration where the conditions 1 and 2 are satisfied and the lower diffuser is short.
