Description

Indoor unit of air conditioner {INDOOR UNIT OF AN AIR CONDITIONER}

The present invention relates to the configuration of an indoor unit of an air conditioner, and more particularly, to an indoor unit in which a front cover having decorativeness or functionality in an indoor unit is disposed in a front portion thereof.

As an indoor unit of a conventional split air conditioner, there is a decorative thing. Utility Model Registration No. 3027900 or Chinese Utility Model Registration No. 99219655 discloses a box-shaped air conditioner installed on an upper surface of an interior. Such a box-shaped air conditioner has a light emitting part such as a fluorescent lamp in a central portion of the front surface of a frame, and has a picture, a photo, etc. having decorativeness on the front side as a film. In the same idea, Chinese Utility Model Registration No. 98211693 discloses a wall-mounted one. Further, Japanese Patent Application No. 2000-161706 discloses that a decorative element is improved by introducing a light emitting element such as an LED between suction holes of a front panel serving as a suction part in an indoor unit of a wall-mounted air conditioner. All have been devised for research on the function to operate the air conditioner installed in the air-conditioned space as one of the decorative interior, and is actually commercialized.

On the other hand, dust is easily attached to the slit of the front grill as described above and is difficult to clean because it is installed in a high place. For this reason, in recent years, studies for requesting cleanliness have been conducted, as disclosed in, for example, Design Registration No. 949996 and Design Registration No. 944062. In other words, the suction part of the indoor unit is only above the case or above and a part just above the blowout part, and the front panel is embodied in a shape having a decorative design on a flat surface or a curved surface without suction holes.

Moreover, according to the demands of the sales customers, researches are being conducted to differentiate products in each of them by customizing them based on basic model designs and designs. For example, only the front grille of the air conditioner is designed by changing the shape, and a part of the front grille is attached with a different color seal.

In this way, the indoor unit of the air conditioner requires decoration because it is disposed in the room that enters the eyes of the user. On the other hand, in particular, the indoor unit of the wall-mounted air conditioner is provided with a slit penetrating at the front side in order to compact the structure of the heat exchanger or the like in the interior thereof, so as to constitute the air intake unit. Therefore, in order to require decorativeness for the indoor unit of the air conditioner having such a slit, only the shape of the slit has been devised in shape such as bending and step.

In addition, since the wall-mounted air conditioner generates static electricity during operation and is partially charged, dust scattering around is attached to the front grill or the like. In addition, since it is arrange | positioned at the high place which a user does not reach normally as mentioned above, it cannot fully clean.

In addition, there is a simple method of attaching a seal to a surface without a suction hole of the front grille, but it is also difficult to produce a sense of quality as an interior. However, in order to change the shape of the front grille according to the type and customer's requirements, each mold is required, leading to an increase in cost.

The indoor unit of the air conditioner of the present invention includes a front cover detachably disposed so as to cover the front part of the indoor unit having a frame body having a front frame.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to what comprises the same structure, and detailed description is abbreviate | omitted.

(Example 1)

BRIEF DESCRIPTION OF THE DRAWINGS It is a schematic block diagram of the indoor unit of the air conditioner in Example 1 of this invention. The frame of the indoor unit 1 is composed of a combination of the frame 2 and the front frame 3, and is provided with electrical components, heat exchangers, perfusion fans, filters, and the like (not shown above). Moreover, in order to operate as an air conditioner, it has the intake port 5 provided with the inlet 4 on the upper surface of a case as a blower circuit, and the flat 6 for wind direction control in the lower part. On the other hand, the front grille 7 is detachably disposed with respect to the front frame 3 on the front surface of the indoor unit 1. When cleaning the filter disposed inside the indoor unit, the front grille 7 is opened by rotating the hinge 7d upwardly of the main body center. Thus, since the front grille 7 can be opened, the inside of a unit is easy to clean. In addition, the same effect is obtained even if the front grille 7 can be opened and closed instead of being detachable.

In the indoor unit of the air conditioner according to the present embodiment, the front cover 8 is further mounted at the front of the front grill 7. The front cover 8 may be fixed to the front grill 7 by adhesion, rib welding, or the like, or may be detachably arranged by engagement with a nail or a screw. Alternatively, as shown in Fig. 1, a 'co'-shaped engagement portion, such as being dragged and hung on the periphery of the front grille 7, is formed on the side side 8f, and the upper portion of the front grille 7 has a hole and The fitting ribs 8d may be provided to engage with each other. In this case, the ribs of the lateral 'コ' shape are pushed and widened to fit the front grille 7. In addition, although the front cover 8 showed the structure which engages with respect to the front grille 7 here, when the front grille 7 does not open and close or is not removable, it is attached to the front frame 3 May be engaged.

In FIG. 1, the front cover 8 is comprised so that only the front grille 7 may be engaged. For this reason, it can be interlocked with the opening-closing operation of the front grille 7, or the attachment / detachment of the pre-filter installed inside, the internal inspection and the like.

The front cover 8 may have a coloring or shape design in order to improve designability. By this, the user can easily change the interior property by changing only the front cover 8. In order to have a certain degree of strength, ribs are formed on the rear surface of the front frame 3, but the entire front grille 7 does not need to be made of the material of the front cover 8. The strength is secured by the front grille 7 and the decoration is performed by a material constituting the front cover, so that a material having priority on securing designability can be selected at a lower cost.

In addition, when the front cover 8 is comprised from the transparent material represented by acrylic, ABS, etc., for example, it will create a sense of quality by the gloss. In addition, if the design figure 7f is molded in the front grille 7, it is permeable from the front surface and is recognizable, and it matches well with the gloss and coloring of the front cover 8 to further improve the designability. In the present example, a male shape was provided as a design drawing 7f. Here, the transparent material constituting the front cover 8 is not colorless but may be transmitted and recognized even though it is colored thinly in various colors. It is also possible to spectroscopically color light such as fluorescent light or sunlight. In addition, a photograph or a picture may be sandwiched between the front grille 7 and the front cover 8, and the design is also functionally suitable even if a sheet-shaped temperature sensor whose color changes with temperature is used. When the front cover 8 is transparent, when the dust adheres to the surface of the front grille 7 by static electricity or the like, it is not good to see. However, if the front cover 8 is detachable as described above with respect to the front grille 7, the cleaning thereof is also easy.

Furthermore, the front cover 8 has an engagement recess 8a that engages with the engagement protrusion 7a formed in the front frame 3. And the light emitting part 7b, such as LED built in the engagement convex part 7a, forms the surface direction of the front cover 8, ie, the direction which forms the surface of the front cover 8 substantially (radiation shown by X in the figure). Light emitting) in the direction of the arrow shown by the shape. As a result, when the surroundings become dark at the time of operation of the air conditioner or the like, the sensor detects them and emits them in various colors to enhance design. For example, a warm color LED emits light when heated, and a cool color LED emits light when cooled. At this time, the peripheral part 8b and the bend part 8c of the front cover 8 are colored and recognized by light transmission, and the illumination effect in a dark place is obtained.

Moreover, by fitting the engagement convex part 7a and the engagement recessed part 8a, the positioning at the time of mounting of the front cover 8 is easy.

In addition, although the light emitting part 7b is provided in the center engaging projection part 7a in this embodiment, as long as it can transmit to the surface direction of the front grille 8, the position is not specifically limited. However, if it is comprised as mentioned above, it will light-emit from the engagement convex part 7a. This ensures positioning of the light emitting portion 7b and the front cover 8. Then, leakage of light from the light emitting portion 7b is eliminated. In addition, by providing the light emitting portion 7b at least in the front frame 3, it is possible to efficiently configure the light source because it is not necessary to arrange the light source separately.

In addition, the engagement convex part 7a may be formed in the front grille 7. In this case, electricity is supplied to the light emitting portion 7b through a contact (not shown) provided at the engaging portion between the front grill 7 and the front frame 3.

(Example 2)

It is a schematic diagram of the structure of the indoor unit of the air conditioner in Example 2 of this invention. In addition, the overview structure of this embodiment is the same as that of the first embodiment. In the present embodiment, the front cover 8 is made of a resin material formed by inserting conductive materials such as carbon, and is provided in engagement with the front grill 7 as in the first embodiment. The front cover 8 is configured in such a manner that the front cover 8 is inserted so as to be inserted along the engaging portion from the upper side with respect to the front grill 7, and is suitable in terms of detachability and the like. The conductive contact 9a contacts the side portion of the front cover 8 at the time of closing the front grille 7. The conductive contact 9a is electrically connected to the earth terminal 9b disposed inside the electric component 9, and is further connected to the ground unit at the indoor unit 1 or the outdoor unit (not shown). Since the heat exchanger and the pipe are usually connected to the earth through an outdoor unit, a power supply line, or the like, static electricity can be easily removed from the case. With this configuration, since the static electricity of the front cover 8 is eliminated, it is less likely to attach dust existing in the surroundings to the surface thereof, and the effort of cleaning the front grille 7 or the front cover 8 is less effortlessly. Can be.

In addition, although the above embodiment was demonstrated about the indoor unit of the wall-mounted air conditioner, you may apply to a ceiling-mounting type, a floor arrangement type, etc. What is necessary is just to replace "front surface" with "bottom surface" in the above description in the case of a ceiling-mounting type.
