Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air conditioner equipped with a drain treatment device.

Conventional configuration and its problems 2. Conventionally, this type of air conditioner has been configured as shown in FIGS. 1 and 2.

In the figure, 1 is an evaporator, and 2 is an indoor fan. When the indoor fan 2 rotates and the evaporator 1 performs heat absorption, dehumidification is also performed at the same time, and water vapor in the air condenses to become drain water. A drain pan 3 is provided below the evaporator 1 to receive drain water flowing down inside the evaporator 1. The drain dish 3 is extended to the immediate vicinity of an outdoor fan 4 installed vertically with many blades, and drops drain water onto a water sprinkling disk 6 attached to the outdoor fan 4. The outdoor fan 4 rotates to promote the heat dissipation action of the condenser 6.

Drain water stored in a drain tray 3 is dropped onto a water sprinkling disk 6 that rotates together with an outdoor fan 4, thereby becoming fine ice particles and scattering around. A part of the drain water scattered at this time is splashed onto the condenser 6, thereby promoting heat dissipation. However, when the drain water is dropped onto the water sprinkling disk 6, it also hits the many blades of the outdoor fan 4, generating a loud noise. Further, a part of the drain water 3, - scattered by the water sprinkling disk 6 hits the condenser 6 and evaporates, but the rest hits the wall surface and accumulates on the substrate 7. It is necessary to provide a drain port 8 so that the drain water accumulated on the substrate 7 does not spill from the substrate 7.

As described above, this configuration has the problem that when the drain water is splashed, it hits many blades of the outdoor fan 4, which generates a loud noise.

There was a problem in that a drain port 8 had to be provided.

Purpose of the Invention The present invention solves the above-mentioned problems with conventional air conditioners, and in addition to preventing noise, □ freely controls the height and amount of splashing even for drain water mixed with dust;
The object of the present invention is to provide an air conditioner equipped with a simple and space-saving drain water treatment device that does not require a drain port by mixing the drain water into the discharge airflow and completely discharging the drain water into the air. be.

Structure of the Invention To achieve this object, the present invention provides a drain water treatment system comprising a short cone body and a rotating device for rotating the cone body, the lower rotation radius being larger than the upper rotation radius, between the condenser and the fan. The device is configured so that the rate of increase in the radius of rotation of this cone is not uniform, and the pumping amount and pumping height can be freely controlled even in drain water mixed with dust, and it can quietly and efficiently dissipate heat. It is possible to completely evaporate drain water by increasing the heat exchange capacity.

DESCRIPTION OF EMBODIMENTS The present invention will be described below with reference to the accompanying drawings of FIGS. 3 to 6 showing an integrated air conditioner which is an embodiment of the present invention.

In the figure, 9 is an evaporator, and when the indoor fan 1o is rotated to blow air, the heat absorption action of the evaporator 9 is promoted, and at this time, the evaporator 9 also performs a dehumidifying action. Drain water generated by dehumidifying the air collects in a drain pan 11 provided below the evaporator 9. This drain dish 11 is connected to a drain hose 13 provided through an indoor/outdoor partition plate 12. Drain water in the drain dish11. It passes through the drain hose 12 and accumulates in the chamber 5 and the outer substrate 13. On the other hand, 14 is a condenser,
The outdoor fan 16 blows air to promote heat dissipation. 16 is a drain water treatment device, which has a conical shape 16
It is installed in a ventilation circuit formed by the condenser 14 and the outdoor fan 16, with the apex side 16a of the fan 16a facing downward and at a certain distance from the substrate 13. The drain water treatment device 16 includes:
on the upper end surface 17.

It is connected to a motor 19 by an attached rotating shaft 18. The rate of increase in the radius of rotation of the conical shape 16 is large at the lower part 21a and small at the upper part 21b. Here, the motor 19 is used to rotate the cone, but the rotation of the outdoor fan 16 may also be used.

When the motor 19 rotates the conical shape 16 with the lower end surface 22 slightly submerged in drain water, the drain water in contact with the outer slope 21 of the conical shape 16 is subjected to centrifugal force due to rotation. , it rises on the outer slope 21 due to the action of the component force in the upward direction of the slope of the outer slope 21, which is the result of the combined force of centrifugal force and gravity. The drain water leaves the outer slope 21 at a height at which the centrifugal force becomes larger than the viscous force, and is scattered radially in the horizontal direction perpendicular to the rotating shaft 18. Since the ice particles are uniformly, minutely, and evenly distributed in a circular shape around the rotating shaft 18, the ice particles do not collide with each other, and therefore no water spraying noise is generated. Moreover, since the construction is extremely simple in that the drain water rises up the conical outer slope 21, a quiet and good watering action can be performed normally even with drain water mixed with dust. A portion of the scattered fine ice particles of the drain water are caught in the condenser 14 and evaporated, promoting heat dissipation and improving heat exchange capability. In addition, most of the other ice particles are fine particles, so the outdoor fan 1
It is discharged to the outside along with the air current generated by the rotation of 6. Drain water that adheres to the partition plate 12 and the like and flows down to the substrate 13 again is scattered by the drain water treatment device 16 again. Even in a narrow space where the maximum diameter of the cone is limited by the action of centrifugal force and gravity, the dispersion of ice particles can be done by changing the rotational speed increase rate in multiple stages. The amount of water pumped and the height of the water can be freely controlled. Therefore, drain water will not overflow from the substrate 13 under any temperature conditions, and there is no need to provide a drain port. In addition, since the drain water can be scattered with only the motor 19 and the conical drain water treatment device f16, it does not take up much space and there is no need to pay much attention to the location of the IC in the ventilation circuit.

Effects of the Invention As is clear from the above embodiments, the air conditioner of the present invention includes a cone whose lower rotation radius is shorter than the upper rotation radius and a rotation device for rotating this cone between the condenser and the fan. A drain water treatment device consisting of a cone is provided, and the radius of rotation of this cone is configured so that the rate of increase is not uniform.
The drain water rises due to the action of centrifugal force and gravity, and the amount of water scattered at 1ξ is so high that the centrifugal force becomes larger than the viscous force of the water, so it mixes with dust even in narrow spaces where the maximum diameter of the conical shape is limited. Even for integrated drain water, by dividing the inclination angle of the conical shape into several types, or by making the inclined surface a multidimensional curve and controlling the rotation speed, the amount, height, and area of watering can be freely adjusted. In addition to promoting the heat dissipation of the condenser and improving the heat exchange capacity, the drain water is completely discharged into the air without the need for a drain port because it is discharged outside as fine ice particles on the discharge airflow. It has various effects such as:
