Disclosure of the invention

Problems to be solved by the invention

[0003] The floor-standing air conditioner as described above is often provided with a suction grille having a large number of slits on the front surface, but from the viewpoint of improving the aesthetics when viewed from the front, a relatively small number is used. It is conceivable to provide a suction opening that also has an opening force. In this case, since there is a possibility that the internal structure can be seen from the outside through such a suction opening, it is effective to provide a cover portion behind the suction opening from the viewpoint of further improving the aesthetic appearance. The cover portion extends obliquely upward after the lower end force of the suction opening, and its upper end is positioned at the same height as the upper end of the suction opening. With this cover part, the internal structure can be made difficult to see the external force. On the other hand, however, the provision of the cover part makes it difficult for air to be sucked into the suction opening force, which may increase the suction resistance.

An object of the present invention is to provide a floor-standing type air conditioner that can make an internal structure difficult to see an external force and can suppress an increase in suction resistance.

Means for solving the problem

[0004] A floor-standing air conditioner according to a first invention includes a front panel and a first cover part.

The front panel has a first suction opening located at a height of 600 mm or less from the bottom, and is provided on the front. The first cover extends diagonally upward after the lower end force of the first suction opening. The An angle dl formed by a line connecting the upper end of the first cover portion and the upper end of the first suction opening and a horizontal plane including the upper end of the first suction opening satisfies 0 ° <dl ≦ 45 °.

In this floor-mounted air conditioner, the first suction opening is at a relatively low position with a bottom force of 600mm or less. Therefore, the first suction opening is often located at a position lower than the user's line of sight, and the user looks down on the suction opening from obliquely above. For this reason, the angle range as described above tends to be a blind spot for the user. Therefore, by providing the first cover portion so that the angle dl satisfies the angle range as described above, it is possible to maintain the visibility of the external force as much as possible and to lower the position of the upper end of the cover member. . Thereby, in this floor-standing type air conditioner, it is possible to make the internal structure difficult to see from the outside and to suppress an increase in suction resistance.

[0005] The floor-standing air conditioner according to the second invention is the floor-standing air conditioner according to the first invention, and the angle dl satisfies 5 ° ≤ dl ≤ 35 °.

In this floor-mounted air conditioner, when the angle dl satisfies the above range, it is possible to more appropriately harmonize the difficulty of seeing the internal structure and the suppression of the increase in the suction resistance.

[0006] The floor-standing air conditioner according to the third invention is the floor-standing air conditioner according to the first or second invention, wherein the first suction opening has a height direction dimension of 5 mm or more.

If the height dimension of the first suction opening is too small, the internal structure becomes difficult to see from the outside, and the cover part is unnecessary. However, when the height direction dimension of the first suction opening is 5 mm or more, a cover portion is necessary to make the internal structure difficult to see the external force, and the present invention is particularly effective.

[0007] A floor-standing air conditioner according to a fourth invention is the floor-standing air conditioner according to the first or second invention, wherein the front panel is located at a height of 600 mm or less from the bottom surface. It further has a suction opening. The floor-standing air conditioner further includes a second cover portion that extends obliquely upward from the lower end of the second suction opening. The angle d2 formed by the line connecting the upper end of the second cover part and the upper end of the second suction opening and the horizontal plane including the upper end of the second suction opening satisfies 0 ° <d2≤45 °.

In this floor-mounted air conditioner, the first cover is also used for the angle d2 with respect to the second cover. The same conditions as for angle dl for some are satisfied. For this reason, even when a plurality of suction openings are provided, it is possible to make the internal structure difficult to see the external force and to suppress an increase in suction resistance.

[0008] A floor-standing air conditioner according to a fifth invention is the floor-standing air conditioner according to any of the first to fourth inventions, wherein the first suction opening is provided at an upper portion of the front panel. It is done. The front panel further has a third suction opening. The third suction opening is an opening provided in the lower part of the front panel and having a height dimension larger than that of the first suction opening. The floor-standing air conditioner further includes a third force bar portion extending obliquely upward after the lower end force of the third suction opening.

In this floor-mounted air conditioner, the first suction opening is provided at the top of the front panel. Generally, the more the suction opening is provided above, the shallower the line of sight of the user and the easier it is to see the internal structure. However, in this floor-mounted air conditioner, the first cover portion can make the internal structure difficult to see by satisfying the condition regarding the angle dl. On the other hand, since the third suction opening is provided at the lower part of the front panel, the angle of the user's line of sight is tight and the internal structure is difficult to see. For this reason, the internal structure of the third suction opening is difficult to see even if the height dimension is larger than that of the first suction opening. For this reason, it is difficult to see the internal structure and the suction resistance can be reduced.

[0009] A floor-standing air conditioner according to a sixth aspect of the present invention is the floor-standing air conditioner according to the fifth aspect of the present invention, wherein a line connecting the upper end of the third cover part and the upper end of the third suction opening, 3An angle d3 with the horizontal plane including the upper end of the suction opening satisfies 0 ° <d2 ≤ 45 °.

In this floor-mounted air conditioner, the angle d3 satisfies the above conditions for the third cover. For this reason, the internal structure of the third cover portion can be made difficult to see from the outside, and an increase in the suction resistance can be further suppressed.

[0010] A floor-standing air conditioner according to a seventh invention is the floor-standing air conditioner according to the fifth or sixth invention, wherein the line connects the upper end of the third cover part and the upper end of the third suction opening. And the angle d3 formed by the horizontal plane including the upper end of the third suction opening is larger than the angle dl.

In this floor-mounted air conditioner, the angle d3 related to the third cover part is larger than the angle dl related to the first cover part. For this reason, the suction resistance at the third suction opening is further reduced. Can. In addition, since the third suction opening is located at a position lower than the first suction opening, it is difficult to see the internal structure having a wider dead angle than the first suction opening. Thereby, in this floor-standing type air conditioner, the internal structure of the third suction opening can be made difficult to see from the outside, and the increase in suction resistance can be further suppressed.

The invention's effect

[0011] In the floor-standing air conditioner according to the first aspect of the invention, the first suction opening is at a relatively low position with a bottom force of 600 mm or less. Therefore, the first suction opening is often located at a position lower than the user's line of sight, and the user looks down on the suction opening with an oblique upward force. For this reason, the angle range as described above tends to be a blind spot for the user. Therefore, by providing the first cover portion so that the angle dl satisfies the angle range as described above, it is possible to maintain the visibility from the outside as much as possible and to lower the position of the upper end of the cover member. . Thereby, in this floor-standing type air conditioner, it is possible to make the internal structure difficult to see from the outside and to suppress an increase in the suction resistance.

In the floor-standing air conditioner according to the second aspect of the present invention, when the angle dl satisfies the above range, it is possible to more appropriately harmonize the difficulty of seeing the internal structure and suppressing the increase in suction resistance. I'll do it.

[0012] In the floor-standing air conditioner according to the third invention, the height direction dimension of the first suction opening is 5 mm or more. In this case, the present invention is particularly effective.

In the floor-standing air conditioner according to the fourth aspect of the invention, the same condition as the angle dl related to the first cover part is satisfied with respect to the angle d2 related to the second cover part. For this reason, even when a plurality of suction openings are provided, if the internal structure can be made difficult to see the external force, the suction resistance can be prevented from increasing.

In the floor-standing air conditioner according to the fifth aspect of the invention, the first suction opening is provided in the upper part of the front panel. In general, the more the suction opening is provided above, the shallower the user's line of sight and the easier it is to see the internal structure. However, in this floor-mounted air conditioner, the first cover portion can make the internal structure difficult to see by satisfying the above-mentioned condition regarding the angle dl. On the other hand, since the 3rd suction opening is provided in the lower part of the front panel, the angle of the user's line of sight becomes tight and the internal structure is difficult to see. Therefore, the third suction opening With regard to the mouth, even if the height dimension is made larger than that of the first suction opening, it is difficult to see the internal structure. This makes it difficult to see the internal structure and reduces the suction resistance.

[0013] In the floor-standing air conditioner according to the sixth aspect of the invention, the angle d3 of the third cover portion satisfies the above condition. For this reason, the internal structure of the third cover portion can be made difficult to see from the outside, and an increase in the suction resistance can be further suppressed.

In the floor-standing air conditioner according to the seventh aspect of the invention, the angle d3 related to the third cover part is larger than the angle dl related to the first force bar part. Therefore, the suction resistance at the third suction opening can be further reduced. In addition, since the third suction opening is located at a lower position than the first suction opening, it is difficult to see the internal structure having a wider dead angle than the first suction opening. Thereby, in this floor-standing type air conditioner, regarding the third suction opening, the internal structure can be made difficult to see from the outside, and the increase in suction resistance can be further suppressed.

[0027] Features>

(1)

In this floor-mounted air conditioner 1, the first suction opening 10a is at a relatively low position of 600 mm or less from the bottom surface B, and is often located at a position lower than the user's line of sight. The diagonal upward force is also looked down at the suction opening. Therefore, the range where the angle dl is 45 ° or less is likely to be a blind spot for the user. For this reason, by providing the first cover portion 17a so that the angle dl is 45 ° or less, it is possible to ensure the difficulty of seeing the inside of the casing 2. Further, the first cover portion 17a is provided so that the angle dl exceeds 0 °, that is, the upper end of the first cover portion 17a is lower than the upper end of the first suction opening 10a. Suction resistance can be reduced. In this way, by providing the first cover portion 17a so as to satisfy 0 ° <d 1 ≤45 °, it is possible to maintain the visibility from the outside as much as possible and to reduce the suction resistance.

[0028] It should be noted that the above effect is the same for the second suction opening 10b and the second cover portion 17b.

(2)

In this floor-mounted air conditioner 1, since the height direction dimension of the first suction opening 10a is about 10 mm, the internal structure is easier to see than when the height direction dimension is less than 5 mm. For this reason, a cover part is necessary to make the internal structure difficult to see from the outside. Therefore, by providing the first cover portion 17a as described above, it is possible to make the internal structure difficult to see from the outside and to suppress the adverse effect of increasing the suction resistance due to the provision of the first cover portion 17a. Monkey. This effect is the same for the second suction opening 10b and the second cover portion 17b.

[0029] (3)

In the floor-standing air conditioner 1, the first suction opening 10a and the second suction opening 10b are provided in the upper part of the front panel 22. In general, the more the suction opening is provided above, the shallower the line of sight of the user (closer to the horizontal), so that the internal structure becomes easier to see. Further, the larger the dimension in the height direction of the suction opening, the easier it is to see the internal structure. Therefore, in this floor-mounted air conditioner 1, the internal structure is made difficult to see by relatively reducing the height dimensions hi and h2 of the first suction opening 10a and the second suction opening 10b. Further, by providing two suction openings, the height dimension of one suction opening can be reduced and the air volume of the suction air can be secured.

On the other hand, since the third suction opening 18 is provided in the lower part of the front panel 22, the angle of the user's line of sight is tight and the internal structure is difficult to see. For this reason, even if the third suction opening 18 has a larger dimension in the height direction than the first suction opening 10a, it is difficult to see the internal structure. Therefore, in this floor-mounted air conditioner 1, the height direction dimension h3 of the third suction opening 18 is larger than that of the first suction opening 10a, and the suction resistance is low. Further, since the third cover portion 19 is provided so as to satisfy 0 ° <dl ≦ 45 °, the suction resistance is lower. In addition, since the third cover portion 19 is provided in a portion that easily enters the line of sight of the user, it is possible to suppress noise inside the casing 2 from leaking to the outside, and to achieve a sound insulation effect.

[0030] <Other Embodiments>

(A)

In the above embodiment, a force satisfying 0 ° <dl ≦ 45 °, more desirably 5 ° ≦ dl ≦ 35 °. The same applies to the angle d2 and the angle d3.

(B)

In the above embodiment, the force angle dl, the angle d2, and the angle d3 where dl = d2 = d3 may be different in magnitude. Further, the angle dl and the angle d2 may have the same size and only the angle d3 may have a different size. For example, angle d3 is greater than angle dl and angle d2. You may ask. Since the third suction opening 18 is located below the first suction opening 10a and the second suction opening 10b, the inner portion of the user's blind spot is large even if the angle d3 is larger than the angle dl. The structure can be made difficult to see external force.

Industrial applicability

INDUSTRIAL APPLICABILITY The present invention has an effect that the internal structure can be made difficult to see the external force and an increase in the suction resistance can be suppressed, and is useful as a floor-standing type air conditioner.
