Abstract

(57) [Problem] To provide an integrated air conditioner in which suction of condensed water by a blade of a propeller fan and scattering in the machine are prevented without increasing suction resistance of the fan. SOLUTION: On a windward side of a base 1 and a portion corresponding to a blade 8b of a propeller fan 8 with a slinger ring 8a, a projecting portion 21 which is substantially the same as or slightly higher than the water surface of the condensed water is separately formed of synthetic resin or the like. Since it is formed integrally with the body or by narrowing the base, the suction of condensed water by the propeller fan with slinger ring can be eliminated, and the condensed water can be prevented from scattering into the machine.

On the inside 2, a dew tray 14, an indoor heat exchanger 13 placed above the dew tray 14, a ventilation casing 11, and a ventilation casing 11
And the indoor blower fan 10 housed in the
In addition, an outdoor heat exchanger 9 and a slinger ring 8 for stirring up condensed water flowing from the dew tray 14 and remaining on the base 1.
a with a propeller fan 8, a baffle plate 7, a compressor 6,
A fan motor 5 for driving the indoor blower fan 10 and the propeller fan 8 is provided, and a part of the propeller fan 8 with the slinger ring 8a is sucked up by a part of the propeller fan 8 with the slinger ring 8a in a part near the bell mouth 7a provided in the air guide plate 7. A water shield plate 7b for preventing the condensed water from scattering outside the machine is provided, and the condensed water is atomized by the slinger ring 8a and blown to the outdoor heat exchanger 9 to increase the heat exchange efficiency. However, in this configuration, since the water shield plate 7b does not cover the entire circumference, as shown in FIG. 3, the condensed water is sucked up by the blade 8b of the propeller fan 8 with the slinger ring 8a and adheres to the blade 8b. There is a problem that the air is blown off by the centrifugal force of the fan 8 and scattered in the machine, and wets the compressor 6, the fan motor 5, and the like. In addition, if the water impervious plate 7b is provided on the entire circumference in order to prevent scattering in the machine, there is a problem that the suction resistance of the propeller fan 8 increases and the air volume decreases.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and prevents the condensed water sucked up by the blades of the propeller fan from scattering into the machine without increasing the suction resistance of the fan. It aims to provide an air conditioner.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a partition plate for partitioning between the indoor side and the outdoor side is provided substantially at the center of the base, and a dew tray is provided on the indoor side. An indoor heat exchanger placed above the dew tray, a blower casing, and an indoor blower fan accommodated in the blower casing are placed, and an outdoor heat exchanger flows into the outdoor side from the dew tray. A propeller fan with a slinger that lifts condensed water accumulated in the base, a baffle plate, a compressor, and a fan motor that drives the indoor blower fan and the propeller fan, and is provided on the baffle plate A part of the bell mouth is provided with a water shield plate for preventing the condensed water sucked up by the blades of the propeller fan with the slinger ring from splashing outside the machine, and the condensed water is atomized by the slinger ring to form the outdoor heat exchanger. Blow on In the integrated air conditioner configured to increase the heat exchange efficiency, the windward side of the base, the portion corresponding to the blade of the propeller fan with the slinger ring, is substantially the same as the water surface of the condensed water, The integrated air conditioner is provided with a slightly high protrusion to prevent the condensed water from being sucked up by the propeller fan with the slinger.

[0005] The protruding portion has a mountain-like shape which rises and falls according to the locus of the blade of the propeller fan with slinger.
It is an integrated air conditioner composed of two projecting parts.

[0006] An integrated air conditioner is provided in which the protruding portion is formed separately from synthetic resin or the like and is fixed on the base.

According to another aspect of the present invention, there is provided an air conditioner in which the protrusion is formed by a throttle of the base.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, in the integrated air conditioner of the present invention, the water surface of the condensed water is substantially the same as the water surface of the condensed water on the windward side of the base, the portion corresponding to the blades of the propeller fan with slinger ring. Alternatively, since the protruding portion slightly higher than the water surface is provided, it is possible to prevent the condensed water from being sucked up by the propeller fan with the slinger ring and to prevent the condensed water from scattering into the machine. Further, since the projecting portion is formed by the aperture of the base, the number of components is not increased, and the projecting portion is raised and lowered in accordance with the locus of the blade of the propeller fan with the slinger. With this configuration, the water level of the condensed water at the position corresponding to the blade can be lowered, and the suction of the condensed water can be more effectively prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An integrated air conditioner according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a sectional side view showing a main part of an integrated air conditioner according to the present invention, and FIG. 2 is a partially enlarged view of a main part showing an embodiment of the integrated air conditioner of the present invention.
FIG. 2- (B) is a view from the top, and FIG.
FIG. 2- (C) is a sectional view taken along line BB of FIG. 2 (A). In the integrated air conditioner of the present invention, as shown in FIG. 1, a partition plate 4 for partitioning an indoor side 2 and an outdoor side 3 is provided substantially at the center of a base 1, and a dew tray 14 is provided on the indoor side 2. And an indoor heat exchanger 13 placed above the dew receiving tray 14, a blower casing 11, and an indoor blower fan 10 housed in the blower casing 11, and an outdoor heat exchanger , A propeller fan 8 with a slinger ring 8a, which lifts condensed water flowing from the dew tray 14 and accumulated in the base 1, a baffle plate 7, a compressor 6, the indoor blower fan 10, and a propeller fan. A bell motor 7a provided on the baffle plate 7 with a fan motor 5 for driving the

First protruding portion 21a, second protruding portion 21b, and third protruding portion 21c having a mountain shape that rises and lowers in accordance with the trajectory of blade 8b of propeller fan 8 with ring 8a.
Therefore, the condensed water between the first protrusion 21a or the third protrusion 21c and the second protrusion 21b flows downwind due to the wind of the propeller fan 8, and the water level decreases. No more air is sucked up by the blades 8b of the fan 8.

[0013]

As described above, according to the integrated air conditioner of the present invention, the water surface of the condensed water is substantially the same as the water surface of the condensed water on the windward side of the base, the portion corresponding to the blade of the propeller fan with the slinger ring. Or, since the protruding portion slightly higher than the water surface was formed by synthetic resin or the like and provided, eliminating suction of condensed water by the propeller fan with the slinger ring,
It is possible to prevent the condensed water from scattering into the machine. Also,
Since the projecting portion is formed by the throttle of the base, the number of parts is not increased, and the projecting portion is formed by three mountain-like projecting portions which are raised and lowered corresponding to the trajectory of the blade of the propeller fan with the slinger ring. With this configuration, the water level of the condensed water at the position corresponding to the blade can be lowered, and the suction of the condensed water can be more effectively prevented.
