Description

[Detailed Description of the Invention] The present invention relates to an improvement of a floor-standing air conditioner.

Generally, in this type of floor-standing air conditioner,
An air filter is installed on the back of the intake grill located at the front. If dirt and dust accumulate on this air filter, the amount of air sucked in decreases and the heating and cooling effect deteriorates, so there is a need to clean the air filter as necessary.

Conventionally, the structure for taking out the air filter includes, for example, a structure in which the front panel is opened toward the front using the pivot point at the lower end of the panel as a fulcrum;
Alternatively, a configuration is known in which a filter outlet is provided near the bottom of the air outlet located on the top surface of the harmonizer main body, and the air filter is pulled upward from the outlet.

However, with the former panel opening/closing means, a hinge etc. are indispensable for opening and closing, and as a result, not only does the structure of the front panel become complicated, but also the front surface is flush with the front panel when the front panel is closed. There was a design defect because it did not.

Furthermore, the latter configuration, which is configured to be pulled out upwards, not only requires a large amount of space for installing and removing the air filter, but also makes it difficult to install the air filter because it cannot be pulled out upwards when the air conditioner is embedded in the wall. The disadvantage was that there was no freedom.

Therefore, in the present invention, an opening for taking out the air filter is provided in the middle of the front of the front panel, and a suction grill is provided below this opening, continuing from the opening, and is housed on the back of this suction grill, making it flexible. An air filter is provided, which includes a filter body having a filter body and an upper end portion continuous above the filter body, and the upper end portion of the air filter faces the opening between the front panel and the suction grille. The front surface of the upper end, the front surface of the front panel, and the front surface of the suction grill are each flush with each other, while the front panel extends from the lower end of the front panel above the opening to the lower rear side of the front panel, and when the air filter is stored, the rear surface of the upper end portion is flush with the front surface of the upper end. A blind part is provided opposite to the side, and a protrusion is provided in the blind part to prevent the air filter from directly hitting the lower end of the front surface of the front panel when the air filter is taken out. By providing a protrusion on the front surface of the upper end of the filter body, the protrusion has a contact surface that comes into contact with the filter body.
The floor-standing type eliminates the conventional drawbacks mentioned above, allows the air filter to be taken out from the front, provides greater flexibility in installation, allows hot stamping, and does not damage the hot stamped surface with a wood grain pattern. The aim is to provide air conditioners.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Figure 1 is a sectional view of the floor-standing air conditioner according to the present invention. In the figure, 1 is a main body casing, and this main body casing 1 includes a front panel 2, a back plate 3, a bottom plate 4, a top plate, and left and right sides. It is constructed into a substantially rectangular parallelepiped shape with gate-shaped side plates 5 comprising side plate portions.

A suction grill 6 is integrally formed on the front surface of the front panel 2, and a suction port 7 is provided on the front surface of the main body casing 1.

Further, an air outlet grille 8 is attached to an inclined portion connecting the front panel 2 and the upper end surface of the gate-shaped side plate 5, and an air outlet 9 is formed at the upper inclined portion of the main body casing 1.

A heat exchanger 10 is provided approximately at the center of the main body casing 1 facing the suction port 7, and a drain pan 11 is horizontally suspended below the heat exchanger 10.

Further, a fan motor 13 equipped with a centrifugal fan 12 that sucks room air from the suction port 7 and blows it to the blowout port 9 is fixed to the back plate 3, and a scroll 14 is attached to the back plate 3. Further, a bell mouth 16 having a relatively large-diameter intake port 15 integrally formed therein is disposed between the scroll 14 and the heat exchanger 10.

On the other hand, a flexible air filter 18 is interposed between the suction grille 6 and the filter guide 17 behind it, and as the centrifugal fan 12 rotates, room air sucked from the suction port 7 is passed through the air filter 18. After the dust is removed by the heat exchanger 10, the dust is removed from the air by the heat exchanger 10, and then the air is blown into the room again from the outlet 9 by the centrifugal blowing action of the fan 12.

Next, the air filter 18, which is the core of the present invention,
and its surrounding structure will be explained in detail.

An opening 19 for taking out an air filter is provided in the middle of the front surface of the front panel 2. In other words, the opening 19 connects the front panel 2 and the intake grille 6.
This opening 19 is formed between the upper end of the
Below the opening 19, the suction grill 6 is mounted.

The air filter 18 has a filter main body 18e.
and an upper end portion 18a continuous above the filter body 18e, and is removably disposed between the back surface of the suction grille 6 and the filter guide 17, and the upper end portion 18a of the air filter 18
facing the opening 19 between the front panel 2 and the suction grille 6, the upper end front surface 18b of the air filter 18, and the front surface 2b of the front panel 2;
The front surface 6b of the suction grill 6 is flush with the front surface 6b of the suction grill 6, and is located on the same plane. Each front surface, that is, the upper end front surface 1 of the air filter 18.
8b, the front surface 2b of the front panel 2, and the front surface 6b of the suction grille 6 are hot stamped with a wood grain pattern.

Further, the upper end portion 18a of the air filter 18
The shape is similar to the shape of the suction grill 6, and its surface is formed into an uneven shape similar to the lattice of the suction grill 6.

Furthermore, the upper end 18 of the air filter 18
As shown in FIG. 2, a handle 20 for taking out the filter is provided at the center portion in the horizontal direction of a, and guide protrusions 18c, 18c are integrally formed at both left and right ends of the upper end portion 18a.

Further, the upper end portion 18a of the air filter 18 is curved in a curvature shape from the uppermost end to the back surface thereof to form a curvature surface 18d, and the upper end portion 18a and the filter main body 18e of the air filter 18 are connected to each other with a curvature. 18f, and a protrusion 18h having a contact surface 18g that comes into contact with the back surface of the upper end of the suction grille 6 when the air filter 18 is stored is provided on the lower front side of the continuous curvature portion 18f. .

On the other hand, in the front panel 2 near the opening 19, there is a front surface 2b of the panel 2 following the stepped portion 2c.
A blind part 2d parallel to the front face 2b and slightly recessed toward the back side of the front face 2b is integrally formed, and the lower end of the blind part 2d is curved to form a curvature part 2e. In other words, the blind portion 2d extends from the lower end of the front panel 2 above the opening 19 to the lower rear side of the front panel 2, and is provided so as to face the rear side of the upper end portion 18a when the air filter 18 is stored. It is.

The stepped portion 2c above the blind portion 2d is integrally formed with protrusions 2f, 2f so as to face the guide protrusions 18c, 18c. The structure is designed to prevent direct contact with the

The filter guide 17 has screws 2 between the upper and lower protrusions 2g, 2g protruding from the back surface of the front panel 2.
It is fixed using screws 1 and 21.

Next, the effect of the upper track configuration will be explained.

As shown in FIGS. 1 and 2, when the air filter 18 is properly housed, the curvature surface 18d of the air filter 18 is in the blind part 2d of the front panel 2, and the lower surface of the upper end 18a of the air filter 18 is is in contact with the sharp upper end of the suction grill 6, and the contact surface 18g of the air filter 18 is in contact with the back surface of the upper end of the suction grill 6, so that the front surface 18b of the air filter 18 is in contact with the front surface 2b of the front panel 2 and the suction grill 6. It is flush with the front surface 6b of.

To take out the air filter 18, hold the handle 20 and pull the air filter 18 diagonally upward as shown in FIGS. 3 to 5.

That is, at the initial stage of pulling out the air filter 18, as shown in FIG. 3, while pulling the handle 20 slightly forward, the air filter 18 is pulled upward by holding the handle 20. At this time, the curvature portion 18d of the air filter 18
Since the filter 18 comes into contact with the protrusion 2f of the front panel 2, the filter 18 can be pulled out smoothly. In this case, after the protrusion 18h is removed from the upper end of the suction grill 6, the space between the air filter 18 and the suction grill 6 or the filter guide 17 becomes larger, and the air filter 1
8 can be easily removed.

From the state shown in FIG. 3, the air filter 18
If we draw it out further, we get something like Figure 4. Even at this point, the air filter 18 is separated from the hot stamp surface of the front panel front surface 2b by the protrusion 2f of the front panel 2, and the air filter 18 is separated from the hot stamp surface of the front panel front surface 2b.
Since the protrusion 2f prevents the hot stamp from hitting the hot stamp surface, there is no fear that the hot stamp surface will be damaged or the hot stamp will peel off.

Next, when the air filter 18 is pulled out further upward from the state shown in FIG. 4, it becomes as shown in FIG. Since the air filter 18 is separated from the hot stamp surface, the air filter 18 can be taken out while the hot stamp surface is well protected. Moreover,
Since the air filter 18 can be pulled out obliquely upward from the front surface of the main casing 1, the degree of freedom in installing the air conditioner can be ensured.
It is also possible to embed the air conditioner in the wall.

As described in detail above, the present invention has an opening 19 in the middle of the front surface of the front panel 2 for taking out the air filter.
A suction grill 6 is provided below the opening 19 following the opening 19, and a flexible filter body 18e is housed on the back side of the suction grill 6 and is connected above the filter body 18e. An air filter 18 is provided, and the upper end 18a of the air filter 18 is connected to the opening 19 between the front panel 2 and the suction grille 6.
The upper end front surface 18b of the air filter 18, the front panel front surface 2b, and the suction grille 6b are flush with each other, and from the lower end of the front panel 2 above the opening 19 to the lower rear side of the front panel 2. a blind portion 2d that extends to and faces the back side of the upper end portion 18a when the air filter 18 is stored;
The blind portion 2d is provided with a protrusion 2f that prevents the air filter 18 from directly abutting the lower end of the front panel front surface 2b when the air filter is taken out, and also abuts against the back surface of the upper end of the suction grille 6 when the air filter 18 is stored. Protrusion 18 having a contact surface of 18g
h is provided on the front surface of the upper end of the filter body 18e, which eliminates the drawbacks of the conventional structure described above and allows the air filter 18 to be taken out from the front surface, resulting in greater freedom of installation. It has the effect of

Further, the upper end front surface 1 of the air filter 18
8b, front panel front 2b, and intake grill front 6b
Since they are flush with each other, hot stamping can be easily applied.

Further, when the air filter 18 is in a normal storage state, the upper end 18a of the air filter 18
The back surface contacts the blind portion 2d of the front panel 2, and the contact surface 8g of the protrusion 18h on the front surface of the upper end of the filter body 18e contacts the back surface of the suction grille 6, thereby reliably storing and holding the air filter 18.
When the air filter 18 is taken out, after the protrusion 18h is removed from the suction grille 6, the space between the air filter 18 and the suction grille 6 is enlarged to facilitate the removal operation of the air filter 18. Also, the blind part 2 of the front panel 2
Since the protrusion 2f is provided at d, even if the air filter 18 comes into contact with the front panel 2 due to contact between the suction grille 6 and the protrusion 18h when the air filter 18 is taken out, the protrusion 2f will prevent the air filter 18 from coming into contact with the front panel 2. As a result, the air filter 18 is forcibly separated from the front panel 2, and the air filter 18 can be prevented from hitting the hot stamp surface. Moreover, by providing the projection 18h, it is possible to check the storage state of the air filter 18, and when the projection 18h is not completely stored in the back surface of the suction grill 6, the upper end portion 18a protrudes from the front panel 2. Air filter 18
On the other hand, when the protrusion 18h is stored in the back of the suction grill 6, the air filter 18 is also almost completely stored, and this is confirmed.
This has remarkable effects such as making the installation work more reliable.
