Description

[Detailed description of the invention] This invention actively generates and collects condensed water on the partition wall that divides the inside of the device into a suction side and an outlet side, thereby reducing the need for insulation and reducing the size of the device. This article relates to an air conditioner designed to achieve the following.

In general, air conditioners include a top-blowing indoor unit in which a cross-flow fan 2 is disposed above a housing 1 and a blow-off port 3 is formed above, as shown in FIG.

In this top-blowing type, the so-called flow path area of the blowing side 5 defined by the heat exchanger 4 is large. The disadvantage is that not only does it take an extremely large amount of time, which increases the cost, but also requires a great deal of effort to ensure quality in manufacturing.

On the other hand, what has been proposed to effectively eliminate the above-mentioned drawbacks is a bottom-blowing type air conditioner in which a suction port 3' is formed downward, as shown in FIG.

In this device, a partition wall 7 whose one end is connected to the upper end of the heat exchanger 4 is arranged in the direction of gravity, and divides the inside of the casing 1 into an upper suction side 8 and a lower blowout side 5'. The flow path area of 5' is made small.

Therefore, the bottom blowing type requires far less heat insulating material 6 than the above-mentioned top blowing type.

However, since the bottom-blowing air conditioner requires a large area for the suction port 9, the partition wall 7 inevitably covers the heat exchanger 4. In this case, a heat insulating material 6 is required to prevent the generation of condensed water due to the temperature difference between the front and back surfaces, and there is a problem in that the size of the device is increased.

The present invention was devised to solve the above problems all at once, and its purpose is to create an air conditioner that can omit the need for insulation, thereby reducing the size of the device, and which is advantageous in terms of cost and quality. The purpose is to provide a simple configuration.

A preferred embodiment of the present invention will be described below in detail with reference to the drawings from FIG. 3 onwards.

10 is an indoor unit type air conditioner; this air conditioner 1
A suction port 12 is formed in the upper part of the front surface of the housing 11, and an outlet port 13 is formed in the lower part.

A cross-flow fan 14 is installed above the housing 11, and a heat exchanger 15 is installed below the cross-flow fan 14 with its lower end in contact with the rear wall 11a of the housing 11 and is inclined slightly forward. ing.

On the other hand, the lower end of the rear wall 11 a constituting the housing 11 is bent forward, and a heat insulating material 16 is stretched on the back surface of the rear wall 11 a to form a drain tray 17 at the inner bottom of the housing 11 .

A partition wall 18 is disposed in the housing 11 from the upper end of the heat exchanger 15 to the boundary 16 between the suction port 12 and the air outlet 13 in the direction of gravity. and a lower blow-off side 21.

That is, as shown in FIGS. 4 and 5, the partition wall 18 has an upper end 18 a and both left and right ends 18 b of the heat exchanger 1
5 is bent rearward so as to surround the upper end portion of the drain plate 17, while both left and right end portions 18b are formed to protrude downward, and a groove 2 for guiding condensed water to the drain tray 17 is formed on the back side of the inner edge portions on both sides.
3 are integrally formed.

Furthermore, a gutter 22 that opens toward the front (suction side 20) is provided below the partition wall 18.

This gutter 22 forms a substantially horizontal slit below the partition wall 18, and the lower piece 18C of this slit is connected to the upper piece 18.
d, and reinforcing ribs 18 are provided at appropriate intervals along the lateral direction between the lower piece 18C and the upper piece 18d.
By integrally forming e, the front upward opening 18 f
Further, a closing plate 18g for air-sealing the opening 18f from the blowing side 21 is attached to the back side of the opening 18f.

A notch 18h is formed on both sides of the closing plate 18g to allow condensed water from the opening 18f to pass into the groove 23.

Next, the operation of the present invention configured as described above will be explained.

In FIG. 3, during cooling operation, the air conditioner 10 sucks air from the suction port 12 with the cross-flow fan 14 into the suction side 20.
from the heat exchanger 15 to the outlet side 21, and the outlet 1
Cool air is emitted from 3.

In such a state, there is a temperature difference between the front and back surfaces of the attached cut wall 18, so that dew condensation water is generated on the surface of the suction side 20, which is the warm air side, due to the temperature and humidity relationship between the suction side 20 and the blowout side 21.

The condensed water generated on the surface of the partition wall 18 flows down due to its own weight and is caught in the gutter 22, and then flows through the grooves 23 on both sides to the drain pan 1.
Leads to 7.

As described above, all the condensed water generated on the surface of the partition wall 18 is collected by the gutter 22.

Therefore, it is not necessary to provide a heat insulating material on the back side of the partition wall 18 to prevent the generation of condensed water, and therefore, the heat insulating material can be omitted, and the size of the device can be reduced accordingly.

In addition, in the above embodiment, the closing plate 18 g that constitutes the gutter 22
Notches 18h were formed on both sides of the plate to allow condensed water to pass through, but grooves 23 were formed in the lower piece 18C without forming the notches 18h.
A recessed portion may be formed to communicate with (not shown).

Further, in the above embodiment, the opening 18 constituting the gutter 22
A reinforcing rib 18e is integrally formed on the reinforcing rib 18e as shown in FIG. 4, but a diversion rib 24 having a triangular cross section as shown in FIG. 6 may be further provided on the reinforcing rib 18e.

That is, the width A of the cut-out surface 25 of the diversion rib 24 on the lower surface side (upper piece 18d) of the dew condensation water flow is set to be larger than the width B of the reinforcing rib 18e, and the width A of the cut-out surface 25
The dew condensation water flow is formed so that it gradually converges upwardly on the lower surface and in the direction of the lower piece 18C along the die cutting surface 25, and the ridgeline connecting the converging points forms a watershed ridge 26 with a strong slope. has been done.

By doing so, 100% of the condensed water can be recovered, the problem of condensed water leaking along the reinforcing rib 1°8e can be solved at once, and the strength of the reinforcing knob 18e can be increased.

Further, the flow dividing rib 24 is not limited to the partition wall 18, but can also be provided on the housing 11 in the case of a top-blowing air conditioner 10'.

(See Figure 7). In summary, according to the present invention, the following effects can be obtained.

(i) Since the condensation water that forms on the partition wall due to the temperature difference between the suction side and the outlet side can be collected by the gutter, there is no need for insulation material on the partition wall to prevent condensation water. This can be omitted, thereby reducing the size of the device.

(ii) Since the heat insulating material can be omitted, it is advantageous in terms of cost and quality.

(iii) Since the configuration is simple, it is easy to manufacture;
It can be provided at low cost.
