Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a rear grill structure of an air conditioner that cools a room and has a function of evaporating condensed water generated in the evaporator by passing it through the condenser. It is something.

BACKGROUND ART In recent years, in order to save energy, attempts have been made to improve the coefficient of performance of air conditioners by using condensed water in a condenser.

An example of the back structure of the above-described conventional structure for applying condensed water to a condenser will be described below with reference to the drawings.

Conventionally, this type of rear structure was used, for example, in 1983-
As shown in Publication No. 22017 or Japanese Unexamined Patent Publication No. 57-104065, the structure was as shown in FIGS. 5 to 7.

That is, as shown in FIG. 5, the condenser 2 is protected by a wire mesh 1 shown in FIG.
Further, in FIG. 7, numeral 3 is a rotating disk that scatters condensed water and applies it to the condenser 2, and 4 is a motor that drives the rotating disk 3. The rotary disk 3 is rotated at high speed to scatter condensed water, and the water droplets are attached to the condenser 2, thereby improving the heat exchange efficiency of the condenser 2 by latent heat of vaporization.

Problems to be Solved by the Invention However, in the above configuration, because the wire mesh 1 is coarse, water droplets that hit the condenser 2 bounce off and fly out of the air conditioner body, causing damage to passersby. This problem occurs, and if a large space is provided for the water droplets to scatter in order to prevent this problem, the space required for the air conditioner itself becomes large.

Means for Solving the Problems In order to solve the above problems, the structure of the rear grill of the air conditioner of the present invention is made of resin molding.
The water splash prevention plate provided near the rotating disk is inclined with respect to the rotational direction of the rotating disk.

Effects With the above-described configuration, the present invention prevents large water droplets directly or water droplets that bounce off the condenser from flying out of the air conditioner body with the water splash prevention plate. Since it is installed in the direction where the most water droplets will fly out, more effective prevention measures can be taken.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

3 shows an upper cross section of the air conditioner main body 5, and FIG. 4 shows a lower cross section of the air conditioner main body 5. In the figure, reference numeral 6 denotes a plurality of vertical louvers A, which constitute an intake grille 7. Reference numeral 8 denotes vertical louvers B, and a plurality of louvers B are provided to constitute the intake grille 7. Reference numeral 9 denotes a water splash prevention plate provided in the vicinity of the rotating disk 3, and is provided at an angle with respect to the rotational direction of the rotating disk 3. 10 is a blowout grille, and 11 is a frame. The louver A6, the louver B8, the water splash prevention plate 9, the outlet grille 10, and the frame 11 are integrally molded from a resin material to constitute a rear grille 12. 13 is a condenser, 14
15 is an indoor cross flow fan 16 is an air guider A, 1 that partitions the indoor side and the outdoor side on the upper side of the air conditioner main body 5.
7 is an air guider B that partitions the indoor side and the outdoor side on the lower side of the air conditioner main body 5; 18 is an evaporator; 19
20 is a stabilizer on the indoor side, 20 is a stabilizer on the outdoor side, 21 is a front grill that also serves as an outer box and is equipped with an intake grill, 22 is a control unit, 23 is a compressor, 24 is a soundproof plate, and 25 is a rotating disk 3. This is the motor that drives the.

In FIG. 1, 26 is a board that serves as the base of each component. 27 is a connecting rib A that reinforces the louver A6, and 28 is a connecting rib B that reinforces the louver B8.

In FIG. 2, numeral 29 is a water tray that receives condensed water generated in the evaporator 18. 30 is the motor 25
The driving force is transmitted to the rotary disk 3 by the motor 25 provided in the control unit 22, passes through the air guider B and passes through the lower part of the condenser 13, and the driving force is transmitted to the condenser 1.
The structure is such that condensed water is scattered from the windward side of No. 3.

The operation of the structure of the rear grill of the air conditioner constructed as described above will be described below with reference to FIGS. 1 to 4.

Condensed water generated in the evaporator 18 is received by a water tray 29, guided to the condenser 13, and collected on the substrate 26. The condensed water that has accumulated on the substrate 26 is scattered in the upward direction a by the rotating disk 3 that rotates at high speed, is applied to the condenser 13, and is evaporated. raise.
Further, since the water splash prevention plate is provided to be inclined with respect to the rotational direction of the rotary disk 3, a relatively large amount of water droplets are prevented from flying out in the inclined direction and toward the outside of the room.

As described above, according to this embodiment, the rear grill 1
Water splash prevention plate 9 provided on the lower side of the intake grill 7 of No. 2
By providing the water droplets at an angle with respect to the rotational direction of the rotating disk, water droplets scattered by the rotating disk 3 are prevented from being scattered to the outside of the room. In addition, the scattered water droplets are effectively applied to the condenser and evaporated without being discharged to the outside, thereby increasing heat exchange efficiency.

Effects of the Invention As described above, the present invention provides a flat plate on the lower side of the suction grill that is inclined with respect to the rotational direction of the rotating disk to prevent water from splashing out.
It is possible to prevent water from splashing to the outside of the room, and eliminate the problem of water splashing onto passersby.

Furthermore, the design of the back side of the air conditioner body can be improved, and it can also be used to protect the condenser.
