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 problems thereof 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 and becomes drain water. . A drain pan 3 is provided below the evaporator 1 to receive the drain 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 5 attached to the outdoor fan 4. outdoor fan 4
rotates to promote the heat dissipation action of the condenser 6, but the drain water accumulated in the drain pan 3 is transferred to the outdoor fan 4.
The water is dropped onto the water sprinkling disk 5, which rotates together with the water droplets, and becomes fine water droplets that are scattered 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 5, it also hits the many blades of the outdoor fan 4, producing a loud noise. Further, some of the drain water scattered by the water sprinkling disk 5 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 that has accumulated on the substrate 7 does not spill from the substrate 7.

In this way, with this configuration, there is a problem that when the drain water is splashed, it hits many blades of the outdoor fan 4 and 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 in conventional air conditioners.It is an object of the present invention to prevent noise and to freely control the splashing height and amount of drain water mixed with dust. A simple and space-saving drain water treatment device that eliminates the need for a drain port by pouring drain water onto the water, evaporating it to promote heat dissipation, and mixing it with the discharge airflow to completely discharge the drain water into the air. The purpose is to obtain an integrated air conditioner equipped with.

Structure of the Invention To achieve this object, the present invention includes a cone between the condenser and the fan, the lower rotation radius of which is shorter than the upper rotation radius, and the lower opening radius of the cone around this cone is shorter than the upper opening radius. The system is equipped with a drain water treatment device consisting of a casing and a rotating device that rotates this cone, allowing the pumping amount and height to be freely controlled and evenly and finely spraying even drain water mixed with dust. This promotes heat dissipation, improves heat exchange ability, and completely evaporates drain water.

DESCRIPTION OF EMBODIMENTS The present invention will be described below with reference to the accompanying drawings of FIGS. 3 to 5 showing an integrated air conditioner as an embodiment thereof.

In the figure, 9 is an evaporator, and when the indoor fan 10 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.
The air is dehumidified and drain water collects in a drain pan 11 provided below the evaporator 9. This drain plate 11
is connected to a drain hose 13 provided through the indoor/outdoor partition plate 12. Drain water passes through a drain pan 11 and a drain hose 12 and accumulates on a substrate 13 on the outdoor side. On the other hand, 14 is a condenser, and the outdoor fan 15 blows air to promote heat dissipation. Reference numeral 16 denotes a drain processing device, which is installed in a ventilation circuit formed by the condenser 14 and the outdoor fan 15 with a certain distance from the substrate 13 with the apex side 17a of the conical shape 17 below. The conical shape 17 is connected to a motor 20 by a rotating shaft 19 attached to an upper end surface 18. The casing 21 surrounds the conical shape 17 at a certain distance and extends upwardly, and is fixed to the indoor/outdoor partition plate 12. The upper end surface 22 of the casing 21 is installed so as to be higher than the upper end surface 18 of the conical shape 17. At this time, the casing 21 may rotate together with the conical body, and here, the conical shape The rotation of the outdoor fan 15 using the motor 20 may be used for the rotation.

When the motor 20 rotates the lower end surface 23 of the conical shape 17 slightly submerged in drain water, the outer slope 2 of the conical shape 17
Drain water in contact with 4 receives centrifugal force due to rotation,
Due to the action of the component force in the upward direction of the slope of the outer slope 24 of the combined force of centrifugal force and gravity, the outer slope 2
4 rise above. The drain water has the conical shape 17 at a height where the centrifugal force becomes larger than the viscous force and overcomes it.
The particles leave the outer slope 24 and scatter radially in a horizontal direction perpendicular to the rotation axis 19. Said outer slope 2
The water droplets that have left the casing 21 collide with the casing 21 at a high speed, become finer due to the energy, and are scattered upward by reflection from the upwardly expanding shape of the casing 21.

The water droplets are uniformly and finely distributed in a circular shape around the rotating shaft 19. Further, since the configuration is extremely simple in that the drain water rises on the outer slope 24 of the conical shape 17, a normal and good water sprinkling action can be performed even when the drain water is mixed with dust. A portion of the scattered fine drain water particles are applied to the condenser 14, promoting heat dissipation and improving heat exchange capability. Most of the remaining water droplets are
Since the particles are ultra-fine and scatter in an upward direction, they are discharged to the outside along with the airflow generated by the rotation of the outdoor fan 15. The casing 21 makes it very easy to collect drain water, and the 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 treatment device 16 again. The scattering of water particles is performed by the action of centrifugal force and gravity, and by changing the rotation speed of the motor 20, the angle of the outer slope 24 of the conical shape 17, and the angle and height of the casing 21, the scattering The height and amount of scattering can be freely controlled. Therefore, drain water does not overflow from the substrate 13 under any temperature conditions, and there is no need to provide a drain port. Further, by providing a slit or the like in the casing 21, it is possible to scatter drain water not only upward but also horizontally in a certain direction. Since water can be pumped up using only the motor 20 and the outer slope 24 of the conical shape 17, and the drain water can be scattered by the casing 21, it does not take up much space and does not require much attention to the installation location within 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 casing around the cone whose lower opening radius is shorter than the upper opening radius. A drain water treatment device consisting of a rotating device that rotates this cone is installed between the condenser and the fan, and uses the extremely simple outer surface of the cone to generate water by the action of centrifugal force and gravity. By causing the drain water to rise, scatter, and collide with the casing, the water particles are made finer and dispersed upward, making it possible to reduce the height and amount of water splashed even in drain water mixed with dust. It can be freely controlled by selecting the rotation speed, the angle of the outer slope of the conical shape, the angle and height of the casing, promoting the heat dissipation effect of the condenser, and discharging it to the outside as fine water droplets on the discharge airflow. Therefore, it has various effects such as being able to completely discharge drain water into the air without providing a drain port.
