Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a window type air conditioner, and more particularly to an improvement in a structure for treating dew generated inside the air conditioner.

[Technical background of the invention and its problems]

Window-type air conditioners are often used because they are easy to install and require less space overall. This type of apparatus is shown in FIG. That is, 1 is a casing, 2 is a bottom plate housed in the bottom of the casing 1, 3 is a front panel, and 4
5 is an indoor heat exchange chamber partitioned by the partition plate 4 and formed inside the casing 1; 6 is also an outdoor heat exchanger; 7 1 is an evaporator, 8 is an indoor fan, 9 is an indoor fan case, 10 is a twin-shaft electric motor, 11 is an outdoor fan, 12 is a condenser, 13 is an outdoor fan case, and 14 is a compressor. Refrigerating cycle equipment such as the evaporator 7, condenser 12, and compressor 14 are communicated via refrigerant pipes to form a refrigeration cycle.

Thus, the compressor 14 is driven, and the two-shaft electric motor 1
By driving 0, cold air is guided into the air-conditioned room.

By the way, the side wall of the partition plate 4 facing the indoor heat exchange chamber 5 is cooled by the cold air, and the temperature of the side wall facing the outdoor heat exchanger 6 drops below the dew point, causing dew formation there. Be looked at.

Further, as shown in FIGS. 2 and 3, there is a rising piece 2a along the periphery of the bottom plate 2, and the side edge of the partition plate 4 is in close contact with the rising piece 2a and is secured with screws. Alternatively, there is a bent piece portion 4a that is fixed by means such as welding.

Therefore, when the dew adhering to the bent piece 4a of the partition plate 4 flows down, it drips to the outside along the rising piece 2a.

Conventionally, in order to prevent this kind of inconvenience, the partition plate 4
In the past, a lot of insulation material was pasted on the roof, but it was not only time-consuming, but also led to increased costs.

[Purpose of invention]

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to improve dew treatment efficiency by preventing dew adhering to the folded pieces from leaking to the outside. The present invention is intended to provide a window type air conditioner that achieves a reduction in cost as well as a reduction in costs.

[Summary of the idea]

In the present invention, a gap is provided to guide dew adhering to the folded piece into the bottom plate, and a protrusion that protrudes toward the rising piece of the bottom plate is provided to tightly fix the folded piece to the folded piece of the partition plate. However, the bent piece above the area where the protrusion of the rising piece and the bent piece come into contact is provided with a protrusion for guiding dew adhering to the bent piece to the gap. be.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 4 and 5. However, since all the parts other than those shown in the above figure are completely the same as the conventional structure shown in FIG. 1, their explanation will be omitted. In the figure, 40a is a bent piece portion of the partition plate 4. This bent piece portion 40a is a part of the partition plate 4.
The rising piece 2 of the bottom plate is bent along the side edge of the bottom plate.
It is formed parallel to 0. Also, this bent piece part 40
A is integrally provided with a protrusion 15 that gradually slopes downward.

The protrusion 15 is a protrusion 20b of the rising piece 20.
It will be provided on the bending piece part 40a above the area where the bending piece part 40a and the bending piece part 40a come into contact.

This rising piece 20 is integrally provided with protrusions 20b that protrude inward with a predetermined gap therebetween. These protrusions 20b are brought into close contact with the bent piece portions 40a and fixed by screws 17.

That is, the bent piece part 40a and the rising piece part 20 are brought into contact with the bent piece part 40a at the protrusion 20b of the rising piece part 20 that protrudes toward the bent piece part 40a side, and fixed with the screw 17, and the rising piece part The gap portion 18 is formed by making the rising piece portion 20 and the bent piece portion 40a non-contact at the flat portion 20a of 20.

On the other hand, the bent piece portion 13a of the outdoor side fan 13
A gap (not shown) is also formed between the rising piece 20 and the bent piece 13a, and a protrusion is also provided on the bent piece 13a.

As a result, dew condensation occurs on the partition plate 4 as the refrigeration cycle operates. Dew that adheres to the bent piece portion 40a and flows down is once received by the protrusion 15 and flows along the slope thereof. The dew dripping from the inclined lower end of the protrusion 15 falls into the gap 18 and accumulates on the bottom plate 2.

The dew that adheres to the bent piece 40a and flows down is directly guided to the bottom plate 2 through the gap 18, and the dew that adheres to the bent piece 40a and flows down is guided to the gap 18 and the bottom plate 2 through the protrusion 15. This prevents a large amount of dew from flowing outside as in the conventional case.

In addition, since the contact between the bent piece 40a and the rising piece 20 of the bottom part 2 is partial rather than the whole as in the conventional case, the cold heat of the cooled bent piece 40a is transferred to the rising piece 20. It becomes difficult to transmit, and the rising piece 2
It is possible to prevent dew from forming on the rising piece 20 due to the cooling of the 0 itself.

In addition, since the head of the fixed screw 17 is located in a recess (protrusion 20b of the rising piece 20 protruding toward the bent piece 40a side) of the bottom plate 2 with respect to the rising piece 20, the bottom plate 2 is attached to the casing 1. The head of the screw 17 does not come into contact with the casing 1 when the screw is inserted into or removed from the casing, thereby protecting the fixed portion (screw 17).

Furthermore, a bent piece 4 is provided on the rising piece 20 of the bottom plate 2.
Since the protruding portion 20b protruding toward the 0a side and the flat portion 20a are bent, the strength of the rising piece portion 20 of the bottom plate 2 can be increased.

Further, in the above embodiment, the protrusion 15 is provided in an inclined manner, but the invention is not limited to this.
As shown in FIG. 6, the projection 15a may be curved in a semicircular shape on the upper half of the projection 16. The cross section of the protrusion 15a is also semicircular as shown in FIG. In this case as well, dew is smoothly guided to the gap 18.

[Effect of idea]

As explained above, according to the present invention, the rising piece and the bent piece are made non-contact at the flat part of the rising piece of the bottom plate to form a gap, and the protruding part of the rising piece The protrusion provided on the bent piece above the area where the part and the bent piece come in contact directs the dew that adheres to the bent piece and flows down to the bottom plate through the gap and the bent piece. Since the dew that adheres to and flows down is guided to the gap and the bottom plate through the protrusions, it is possible to prevent a large amount of dew from flowing outside as in the conventional case.
The bent piece and the rising piece of the bottom plate are connected to the bent piece by a protrusion of the rising piece that protrudes toward the bent piece and are fixed with a screw, and the flat of the rising piece is fixed to the bent piece by a screw. Due to the structure in which the rising piece part and the bent piece part are made non-contact in the supporting part, the contact between the bent piece part and the rising piece part of the bottom plate is not entirely as in the conventional case.
Therefore, the cold heat of the cooled bent piece part is difficult to be transmitted to the rising piece part, and the rising piece part itself is cooled, so that it is possible to prevent dew from forming on the rising piece part.

In addition, the bent piece and the rising piece of the bottom plate are fixed together with the screw by contacting the bent piece with the protrusion of the rising piece that protrudes toward the bent piece. The head of the screw is located in the recess on the rising side of the bottom plate (the protrusion of the rising side that protrudes toward the bent side), so the head of the screw comes into contact with the casing when the bottom plate is inserted into or taken out of the casing. The fixed part (screw) is protected without any damage.

Furthermore, the rising piece of the bottom plate has a protrusion that protrudes toward the bent piece side and a flat part that is bent, so the strength of the rising piece of the bottom plate can be increased and costs can be reduced. be effective.
