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, from the viewpoint of energy saving, efforts have been made to improve the performance of air conditioners by passing condensed water through a condenser.

An example of a conventional configuration in which the above-mentioned condensed water is applied to a condenser will be described below with reference to the drawings.

Conventionally, this type of rear configuration was used, for example, in
As shown in JP-A-22017 and JP-A-57-104065, the configuration was as shown in FIGS. 5 to 7.

That is, as shown in FIGS. 5 and 6, the condenser 2
Some have wire mesh, etc. placed at equal intervals to protect them. Furthermore, as shown in FIG. 7, there is a type having a rotating disk 3 that scatters condensed water and applies it to the condenser 2. Here, 4 is a motor that drives the rotating disk 3. That is, the rotary disk 3 is rotated at a high speed to scatter condensed water, causing water droplets to adhere 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 back and fly out of the air conditioner body and fall on passersby. In order to prevent this problem, if a large space is created for water droplets to scatter, the space required for the air conditioner itself becomes large.

Means for Solving the Problems In order to solve the above problems, the rear grill of the air conditioner of the present invention is made of a resin material, etc., and has a water splash prevention plate near the rotating disk and a dense pitched grill on the lower side. A vertical louver is provided, and a coarsely pitched vertical louver is provided on the upper side.

Effects The present invention has the above-described structure, so that large water droplets that are splashed directly or that have hit the condenser are prevented from flying out of the air conditioner body by the water splash prevention plate.
Furthermore, the densely pitched louvers on the bottom side prevent water droplets from flying out, and the coarsely pitched louvers on the top side reduce air resistance.Furthermore, the air conditioner itself can be made more compact. can do.

Embodiment An embodiment of the present invention will be described below based on the accompanying drawings.

FIG. 1 shows an upper cross section of the air conditioner main body 5, and FIG. 2 shows a lower cross section of the air conditioner main body 5. In the same figure, 6 is a vertical louver A.
The suction grill 7 is constructed by providing a plurality of grilles at intervals of pitch dimension _P1 . 8 is the vertical louver B
The suction grill 7 is constructed by providing a plurality of grilles at intervals of pitch dimension _P2 . Pitch dimension of the louver A
The relationship between P ₁ and pitch dimension P ₂ of the louver B is P ₁
＞ _P2 is determined. 9 is a water splash prevention plate provided near the rotating disk 3, 10 is a blowout grill, and 11 is a frame. The louver A6 and the louver B
8, water splash prevention plate 9, blowout grill 10, frame 11
constitutes the rear grille 12, which is integrally formed from a resin material. 13 is a condenser, 14 is an indoor cross-flow fan, 15 is an outdoor cross-flow fan, 16 is an air guider A 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 body 5; 18 is an evaporator;
9 is an indoor stabilizer, 20 is an outdoor stabilizer, 21 is a front grill that also serves as an outer box and is equipped with an air 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. 3, 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. 4, reference numeral 29 is a water tray that receives condensed water generated in the evaporator 18. Reference numeral 30 denotes a shaft of a motor 25, which transmits driving force to the rotating disk 3 by the motor 25 provided in the control unit 22, passes through the air guider B, passes through the lower part of the condenser 13, and connects the motor 25 to the windward side of the condenser 13. It is designed to scatter more condensed water.

The operation of the rear grill of the air conditioner configured as above will be described below with reference to FIGS. 3 and 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 C by the rotating disk 3 that rotates at high speed, is applied to the condenser 13, and evaporates. raise.
Large water droplets are prevented from flying out to the outside by the water splash prevention plate 9. Relatively large water droplets scatter on the lower side of the air conditioner main body 5, and the tightly pitched louvers 8 prevent the water droplets from flying out to the outside of the room. Further, large water droplets that directly collide with the evaporator 13 and are reflected are blocked by the densely pitched louvers 8. The small water droplets are scattered upward and applied to the condenser 13.

As described above, according to this embodiment, the upper louver pitch of the intake grill of the rear grille is formed coarsely, and the lower louver pitch is formed densely, so that water droplets scattered by the rotating disk 3 are directed to the outdoor side. In addition to preventing water from being blown away, the dense pitch of the lower louvers reduces the opening area on the lower side, increasing the average air intake wind speed and causing water droplets to ride on the wind and adhere to the heat exchanger. In addition, the water droplets scattered on the upper side are small particles, and even if the pitch of the upper side louver is rough and the opening area is large, and the average wind speed of the air is slow, the water droplets can be sufficiently carried by the wind to flow through the condenser 13. At the same time, it can reduce the ventilation resistance of the louver and increase ventilation efficiency.

Effects of the Invention As described above, in the present invention, a rotating disk for scattering condensed water is disposed on the windward side of the condenser, an intake grill is provided to protect the condenser, and the upper side of the intake grill is The louver has coarse vertical pitches, and the bottom side has a flat plate part to prevent water from splashing out, and a louver with dense vertical pitches to prevent water from splashing toward the outdoor side. In addition, it is possible to eliminate the problems caused by blowing on passersby, reduce the ventilation resistance on the outdoor side of the air conditioner body, improve ventilation efficiency, and The design of the back side of the harmonizer body can also be improved, and it can also be used to protect the condenser.
