Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a partition plate erected on the bottom plate of the air conditioner main body, and a resin wind barrel and a resin blowout part are attached to this partition plate, thereby preventing evaporation inside the air conditioner main body. It is divided into a chamber and a condensation chamber.
In addition, by using a heat insulating resin for the resin wind barrel and blowout section, it is not necessary to attach heat insulating material, thereby reducing costs. A chamber is provided in this resin blow-off part or wind barrel so that condensed water, rainwater, etc. can be disposed of smoothly.

As shown in Fig. 10, a conventional integrated air conditioner has a board b that can be freely delivered inside an outer box a, and a metal partition plate c that is erected on top of the board b. The inside of the machine body is divided into an indoor side, that is, an evaporation chamber d side, and an outdoor side, that is, a condensation chamber e side, and the evaporation chamber e side is provided with an evaporator f and an indoor fan g that constitute a refrigeration cycle, and On the condensation chamber e side, a condenser h, an outdoor fan i, a fan motor j, a compressor (not shown), and the like were provided. However, with such a structure, the ventilation passage in the evaporation chamber d is curved at right angles and has corners, which has the drawbacks of high ventilation resistance and increased noise. Furthermore, on the condensation chamber e side, there are limitations on the shape of the partition plate c in terms of processing, so the ventilation passage cannot be made large, which limits the improvement in condensation efficiency.
Furthermore, in order to prevent dew water from adhering to the partition plate c that forms the ventilation path of the evaporation chamber d or the side surface of the condensation chamber e of the top plate k, a heat insulating material (not shown) must be attached to this part. There were some shortcomings, such as:

Therefore, the present invention provides an integrated air conditioner that eliminates these conventional drawbacks, and one embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

In the figure, reference numeral 1 denotes an air conditioner main body, in which a compressor, a pressure reducing device (none of which are shown), an evaporator 2, and a condenser 3, which constitute a well-known refrigeration cycle, are arranged. 4 is an evaporation chamber fan, and 5 is a condensation chamber fan, each of which is fixed to a rotating shaft 7 of a fan motor 6. Reference numeral 8 denotes a partition plate that partitions a part of the interior of the main body 1 into an evaporation chamber side (indoor side) and a condensation chamber side (outdoor side). Also serves as. Reference numeral 10 indicates a wind cylinder that functions as an air guider on the evaporation chamber side, and 11 indicates an outlet on the evaporation chamber side.

Reference numeral 12 denotes an evaporator cover that is provided on the upper part of the evaporator 2 and divides ventilation in the evaporation chamber into a suction side and an outlet side. Next, referring to Figures 2 to 4, the air outlet 11
To explain this, the blow-out portion 11 is provided with a collar portion 13 at the lower end periphery for connection to the wind cylinder 10 . Furthermore, this brim portion 13 has a wind barrel 1
A plurality of connecting portions 14 such as screw holes for connecting to 0 are formed. Also, the flange portion 13 of the blowing portion 11
Hatoyu 15 is formed all around. Blower part 11
Since condensation water, rainwater, etc. adhere to the surface that is in contact with the condensing chamber side, the top surface is sloped by dimension a in order to treat such water.
Further, the flange portion 13 is also sloped with dimension b so that water can be treated smoothly from the top and side surfaces.

FIG. 5 is a perspective view showing the state in which the wind cylinder 10 and the blowing part 11 are connected, and FIGS. 6 and 7 show the state in which the wind cylinder 10 and the blowing part 11 are fixed to the partition plate 8. FIG.

In the above embodiment, the wind barrel 10 and the blowout section 11
Both of these are molded from a synthetic resin material, and the corners of the ventilation passages are curved to reduce ventilation resistance. In addition, even if the shape of the wind barrel 10 is relatively complicated, it can be molded, so the ventilation passage on the condensing chamber side can be made large, and the outdoor air suction port (not shown) formed in the outer box can be made large. Therefore, the amount of air blown to the condenser 3 can be increased, and the condensation efficiency can be increased. Furthermore, the fan motor 6 can be effectively cooled by increasing the amount of ventilation. In FIG. 1, reference numeral 16 denotes a support for fixing the fan motor 6.

Next, another embodiment of the present invention will be described with reference to FIGS. 8 and 9. Note that this example and the first
The same members are indicated by the same numbers in the embodiments shown in FIGS. In this embodiment, the shape of the scroll is different from the embodiments shown in FIGS. 1 to 7. That is, in this embodiment, the evaporation chamber side fan 4 is installed on the partition plate 17 that is installed upright on the substrate 1'.
An opening 18 is formed facing the opening 18, and a pair of opposing grooves 1 extending vertically on both left and right sides of the opening 18.
9 and 19 are formed. Reference numeral 20 denotes a scroll, in which a suction port 21 is formed facing the evaporation chamber side fan 4, and both left and right edges slide up and down along the pair of grooves 19, 19, and the suction port 21 is formed at the lowest end position. 21 and the center of the evaporation chamber side fan 4 are made to substantially coincide. Therefore, in this embodiment, after the wind cylinder 10 is fixed to the partition plate 17 with screws or the like, the scroll 20 is inserted into the grooves 19, 19 of the partition plate 17.
After inserting and installing from above, the blowing part 11 is
It may be screwed to the wind barrel 10. In this embodiment, the partition plate 17, the wind cylinder 10, and the blow-off section 11 partition the air conditioner main body into an indoor side, that is, an evaporation chamber side, and an outdoor side, that is, a condensation chamber side. However, this point is the same as the embodiment shown in FIGS. 1-7.

Furthermore, in both of the embodiments described above, a chamber 15 is formed in the outlet portion 11 to collect and guide dew water or rainwater, but it is clear that this chamber 15 may be formed on the upper edge of the wind barrel 10. . Furthermore, in both of the above embodiments, the wind barrel 10 and the blowout part 11 are molded from synthetic resin material, but if they are molded from a heat insulating synthetic resin material, dew condensation will be reduced.

As is clear from the description of the embodiments above, the integrated air conditioner of the present invention has a partition plate erected on the base plate of the air conditioner main body, and a resin wind body and a resin blowout part are attached to this partition plate. Since the main body is divided into an evaporation chamber and a condensation chamber, the ventilation circuit on the evaporation chamber side can be selected more freely than in conventional structures, and the wind barrel and blow-out section do not function as partition plates in conventional structures. As a result, the ventilation circuit on the condensing chamber side has been improved in terms of space, the area of the condensing chamber suction can be increased, the ventilation resistance can be reduced, and a large amount of air can be sent to the condenser, and the ventilation path on the evaporation chamber side has been made smoother. It can be formed with a curved surface, which can reduce ventilation resistance and noise.
Furthermore, since it uses more resin material than metal materials than conventional structures, it is lighter. Since the wind barrel and the blowout part are divided into two parts, it is easy to replace the evaporation chamber fan, etc.
Serviceability will improve.

Furthermore, since the condensate is provided in the wind barrel or the blow-off section, even if dew condensation occurs in the blow-off section, it becomes easy to provide and dispose of the condensed water. As a result, it is no longer necessary to attach a heat insulating material to the blow-off section, reducing the number of parts, improving workability, and reducing costs. In addition, since the wall thickness of the blow-off section can be made thinner, the air circuit on the evaporation chamber side can be made larger accordingly, the performance of the air circuit on the evaporation chamber side can be improved, and noise can be reduced. Further, since the upper surface of the blowing section is inclined so as to become higher toward the air blowing direction, it is possible to smoothly treat dew condensation water or rainwater that has entered from the outside.
