Description

[0001]
[Industrial application fields]
The present invention relates to a configuration of an indoor unit of an air conditioner.
[0002]
[Prior art]
As an indoor unit of an air conditioner, there is one configured as shown in FIG. 3, for example. In this indoor unit, an air filter 25, an indoor heat exchanger 26, and a blower fan (cross flow) are connected to an air passage 24 connecting a suction port 22 formed in the upper part of the casing 21 and a blower outlet 23 formed in the lower part. A fan) 27 is arranged, and the air direction into the room is adjusted by a wind direction adjusting plate 28 provided at the air outlet 23. The indoor heat exchanger 26 has an upper heat exchanger 26 a whose front surface is inclined forward of the air passage 24, and rear heat which is connected to the upper portion of the upper heat exchanger 26 a and inclined rearward of the air passage 24. It consists of an exchanger 26b and a lower heat exchanger 26c that is connected to the lower part of the upper heat exchanger 26a and is erected almost vertically. The casing 29 constituting the air passage 24 is formed with a boss and the like for fixing the indoor heat exchanger 26, although not shown, together with an upper dew 30 and a lower dew 31 A locking piece 35 that is locked to a locking portion 34 formed on the installation plate 33 fixed to the wall surface 32 is provided.
[0003]
[Problems to be solved by the invention]
By the way, in this type of indoor unit, as described above, the locking piece 35 is provided on the back upper part of the casing 29 constituting the air passage 24, and the locking portion of the installation plate 33 fixed to the wall surface 32. 34, but the gap formed at the rear of the rear heat exchanger 26b is merely a flow path for indoor air, so there is no need to stick to the structure shown in FIG. In this state, the material (resin) is wasted. Accordingly, an object of the present invention is to provide an indoor unit for an air conditioner in which materials are wasted and the components are simplified without degrading the performance as an air conditioner.
[0004]
[Means for Solving the Problems]
The present invention has been made in order to solve the above-described problems. An air filter, an indoor heat exchanger, and an air passage that connect a suction port at the top of the housing and a blow-out port at the bottom of the housing. A blower fan that sends out the air heat-exchanged by the indoor heat exchanger to the air outlet is provided, and a wind direction adjusting plate that adjusts the air direction into the room is provided at the air outlet, and is installed on an installation plate fixed to the wall surface. In the indoor unit of an air conditioner configured as described above, the indoor heat disposed in a manner facing the notch while notching a back side located above the blower fan of the casing forming the casing. A part of the side plate of the exchanger is extended toward the installation plate, and a locking piece that is locked to the locking portion of the installation plate is provided at the tip.
[0005]
[Action]
In the case of the above configuration, a locking piece to be locked to the locking portion of the installation plate is integrally provided on the side plate of the indoor heat exchanger, and the upper back portion of the casing is cut away. The amount of resin to be reduced can be reduced.
[0006]
【Example】
An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows the internal configuration of the indoor unit, and FIG. 2 shows the relationship between the indoor heat exchanger and the installation plate. In the figure, 1 is a housing (indoor unit main body), 2 is an air inlet for indoor air, and 3 is an air outlet directed indoors. A removable air filter 5, an indoor heat exchanger 6, and a blower fan (cross flow fan) 7 are arranged in the air passage 4 connecting the suction port 2 and the blower outlet 3. A wind direction adjusting plate 8 is provided for adjusting the angle up and down. The indoor heat exchanger 6 has an upper heat exchanger 6a whose front surface is inclined forward of the air passage 4, and a rear heat exchange which is connected to the upper portion of the upper heat exchanger 6a and inclined rearward of the air passage 4. And a lower heat exchanger 6c that is connected to the lower part of the upper heat exchanger 6a and is erected substantially vertically. A casing 9 constituting the air passage 4 is formed with a boss and the like for fixing the indoor heat exchanger 6, although not shown, together with an upper dew holder 10 and a lower dew holder 11.
[0007]
By the way, the feature of this embodiment is that the back side (portion indicated by a broken line) 9a of the casing 9 located above the blower fan 7 is cut away to reduce the amount of resin used, while the rear heat exchanger 6b The rear upper parts of the side plates 12 provided on the left and right are extended toward the installation plate 14 fixed to the wall surface 13, and the front end portions thereof are bent outward at substantially right angles to form locking pieces 15. That is, the piece 15 is directly locked to the locking portion (cut-and-raised piece) 16 formed on the installation plate 14. With such a configuration, the indoor unit can be locked to the installation plate 13 without adversely affecting the air blowing performance, and the amount of resin used in the casing 9 can be reduced.
[0008]
【The invention's effect】
If it is an indoor unit as described above, the upper rear surface of the casing that occupies a large area is not necessary, the amount of resin used is reduced, the air flow to the rear heat exchanger is improved, and the heat exchange performance Improvements in product weight, product weight reduction, and productivity can be expected.
