Description

TECHNICAL FIELD The present invention relates to an indoor unit of an air conditioner in which an electrical unit is arranged in front of a heat exchanger.

2. Description of the Related Art An indoor unit of an air conditioner is equipped with a display device that uses light to notify a user of an operating condition, a setting condition, and the like. This display device is provided in the electrical unit. Also, the electrical unit is arranged, for example, on either the left or right side of the heat exchanger in the housing of the indoor unit. Further, in recent years, in order to increase the occupying ratio of the heat exchanger in the housing, there has been proposed an indoor unit in which the length of the heat exchanger in the left-right direction is longer than before. In such an indoor unit, an electrical unit equipped with a display device is arranged in front of the heat exchanger in the housing.

In the case of a conventional indoor unit in which an electrical unit is arranged in front of a heat exchanger, when the front design panel is opened, the electrical unit is exposed, impairing the design. For this reason, a conventional indoor unit in which an electrical unit is arranged in front of a heat exchanger has been proposed to include an electrical unit cover that covers the electrical unit from the front (see, for example, Patent Document 1). .

When covering the electrical unit from the front with the electrical cover, in order to make the display of the display device visible to the user, a display window or display that exposes the display device should be provided at a position facing the display device on the electrical cover. It is necessary to provide a transparent portion for transmitting the light of the device. For example, in the case of the indoor unit described in Patent Document 1, the position of the electrical component cover facing the display device constitutes part of the outer shell of the indoor unit. For this reason, in the case of the indoor unit described in Patent Document 1, the position of the electrical component cover facing the display device serves as a transmission portion through which light from the display device is transmitted. Further, for example, when the position of the electrical component cover facing the display device does not form part of the outer shell of the indoor unit, the position of the electrical component cover facing the display device serves as a display window through which the display device is exposed. Then, a transmitting portion that transmits light from the display device is provided at a position facing the display window on the outer shell of the indoor unit.

As shown in FIGS. 9 to 11, the electrical component cover 31 is provided with a rearwardly protruding first claw 34 at its lower end. It should be noted that four first claws 34 are provided on the electrical component cover 31 in the present embodiment. On the other hand, as shown in FIGS. 12 to 14 , through holes 26 are formed in the electrical component mounting plate 21 at positions corresponding to the four first claws 34 . That is, four through holes 26 are formed in the electrical component mounting plate 21 .

As shown in FIGS. 15 and 16, by inserting the first claws 34 of the electrical component cover 31 into the through-holes 26 of the electrical component mounting plate 21, the first claws 34 of the electrical component cover 31 are attached to the electrical components. It catches on the periphery of the through hole 26 of the mounting plate 21 . Thereby, the electrical component cover 31 is fixed to the electrical component mounting plate 21 .

Here, as shown in FIG. 16, in the present embodiment, each first claw 34 has a first protrusion 35 protruding downward at its lower portion. In addition, the electrical component mounting plate 21 is provided with a second projection 28 that hooks onto the first projection 35 at the lower edge of each through hole 26 . By hooking the second projection 28 on the first projection 35 , it is possible to further restrict the movement of the electrical component cover 31 with respect to the electrical component mounting plate 21 in the vertical and horizontal directions. That is, the movement of the display window 32 in the vertical and horizontal directions with respect to the display device 23 can be further restricted. Therefore, positional deviation between the display device 23 and the display window 32 can be further suppressed, and the design can be further improved.

In this embodiment, the electrical component cover 31 and the electrical component mounting plate 21 are fixed using the four first claws 34 and the four through holes 26, but the number of the first claws 34 and the through holes 26 is Optional. The numbers of the first claws 34 and the through holes 26 may be appropriately determined based on the strength required when fixing the electrical component cover 31 and the electrical component mounting plate 21 .

However, by providing the first claws 34 at the lower end of the electrical component cover 31, the following effects can be obtained.

The electrical component cover 31 is a design part that can be seen by the user when the front design panel 2 is opened. Therefore, the electrical component cover 31 requires attention to design defects. Here, the electrical product cover 31 is generally manufactured by injection molding of resin. When projections such as claws are provided on a resin injection molded product, sink marks, which are a phenomenon in which the surface is dented, are likely to occur on the surface opposite to the surface on which the projections are formed. For this reason, when the electrical component cover 31 is manufactured by injection molding of resin, if the first claws 34 are arranged on the back surface of the electrical component cover 31, for example, in the central portion, the user will find it on the front surface of the electrical component cover 31. There is a possibility that a sink mark may occur in an easy-to-reach place. If the sink marks occur in places that are easy for the user to find, the design of the electrical component cover 31 deteriorates. On the other hand, if the first claws 34 are provided at the lower end portion of the electrical component cover 31, even if a sink mark occurs, the sink mark will occur at the lower end portion of the electrical component cover 31, which is very difficult for the user to see. Become. Therefore, by providing the first claws 34 at the lower end of the electrical component cover 31, deterioration of the design of the electrical component cover 31 can be suppressed.

In addition, when trying to suppress deterioration of the design of the electrical component cover 31, in order to prevent sink marks from occurring in places where the user can easily find them, the back surface of the electrical component cover 31, for example, the central portion, etc. It is also impossible to provide a reinforcing projection or the like on the For this reason, in the conventional indoor unit, when the indoor unit is dropped during transportation, the electrical component cover may be deformed due to the impact, and the electrical component cover may come off. On the other hand, in indoor unit 100 according to the present embodiment, electrical component cover 31 is fixed to electrical component mounting plate 21 as described above. Further, since the electrical component mounting plate 21 is not a design part, even if it is manufactured by injection molding of resin, there is no restriction on the place where the reinforcing projections are provided. Therefore, it is easy to reinforce the electrical component cover 31 . By fixing the electrical component cover 31 to the reinforced electrical component mounting plate 21, the reinforcement of the electrical component mounting plate 21 also reinforces the electrical component cover 31, so that the electrical component cover 31 is not deformed by impact. can be suppressed, and it is possible to suppress the electrical component cover from coming off.

It should be noted that four second claws 27 are provided on the electrical component mounting plate 21 in the present embodiment. On the other hand, as shown in FIG. 17, the drain pan 14 is provided with a hook-shaped projection 15 when viewed from the side. The electrical component unit 20 is fixed to the drain pan 14 by hooking the second claws 27 of the electrical component mounting plate 21 on the convex portion 15 of the drain pan 14 . In addition, in the present embodiment, the through hole 26 and the second claw 27 are positioned at the same position in the left-right direction. However, this is an example of the arrangement of the through holes 26 and the second claws 27 . The through hole 26 and the second claw 27 may be arranged at different positions in the left-right direction.
