Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a drain water treatment structure for a vertical window air conditioner.

[Conventional technology]

A window air conditioner has a compressor, condenser, and evaporator housed in a frame, and the frame is attached to the window that forms the boundary between indoors and outdoors, and an internal blower fan removes condensation from the outside. The air that has passed through the container is blown outside, while the air that has passed through the evaporator inside the room is blown into the room. Then, the indoor air is cooled by the evaporator and blown into the room as cold air, and conversely, the outdoor air is cooled by the condenser, becomes high temperature, and is discharged outdoors.

[Problem that the invention attempts to solve]

The indoor air passing through the evaporator is cooled and the water vapor contained therein condenses, causing water droplets to adhere to the evaporator, and these water droplets are collected and discharged outdoors as drain water.

There are also methods that force the drain water to evaporate by blowing it up with a blower blade and making it adhere to the high-temperature condenser, and there are also methods that force the drain water to vaporize by pumping it up with a special pump and flowing it from the top of the condenser. There is a known method that uses a condenser to force vaporization.

If the drain water could be treated inside the frame in this way, it would be easier to install the air conditioner, but the conventional structure of pumping up the drain water with the fan blades was difficult due to the shape of the fan and the installation of the condenser. Difficult to apply to vertical window air conditioners due to location restrictions.
A common method is to use a pump to pump up drain water and drip it into a condenser.

However, this method also requires the installation of a pump and drain water piping equipment inside the air conditioner, and although it can be applied to most window air conditioners, it is expensive and difficult to manufacture.

[Means for solving problems]

This idea proposes a structure that can easily process drain water by specifying the arrangement of each part of a window air conditioner. 1 is the air conditioner frame, 2 is the A condenser is placed on almost the entire surface of the outdoor side of the frame 1, and an evaporator 3 is placed on the upper front side of the indoor side of the frame 1. The space below the evaporator 3 is equipped with a compressor 4 and a controller. Electronic parts 7
etc. are installed.

5 is a partition plate that divides the upper chamber A in which the evaporator 3 is installed and the lower chamber B that houses the compressor 4; 8 is a partition wall that separates the back chamber C in which the condenser 2 is installed and the upper chamber A; Reference numeral 9 denotes a lower partition plate that separates the lower chamber B that houses the compressor from the space in which control electronic components are installed.

10 is a vertical cross-flow fan installed in parallel with the condenser 2, and the lower chamber B and back chamber C that are in contact with the inner surface of the condenser 2 on the frame 1 side are the cross-flow fan 10.
The air passing through the condenser 2 when the crossflow fan rotates 10 times flows into the crossflow fan 10 via the back chamber C and the lower chamber B, and is discharged outside.

Reference numeral 5' denotes a drain receptacle formed on the upper surface of the partition plate 5, and the drain receptacle 5' (partition plate 5) has a downward slope and its end extends to the vicinity of the condenser 2. 6 is a vaporizing wick attached to the inner surface of the frame 1 of the condenser 2 that looks into the lower chamber B from the upper surface of the drain receiver 5', and the drain water flowing on the upper surface of the drain receiver 5' is sucked into the vaporizing wick 6 and is The air diffuses into the air and vaporizes when it touches the high temperature condenser 2, and the air that has become high temperature in the condenser 2 passes through the vaporization wick 6 and vaporizes the drain water.

[Explanation of action]

In this device having the configuration described above, when the compressor 4 is operated to rotate the cross-flow fan 10 for the condenser 2, and when the cross-flow fan for the evaporator 3 (not shown) is rotated, the compressor 4 performs compression. The refrigerant is liquefied by outdoor air passing through the condenser. Also, the liquefied refrigerant passes through the chia pillar to the evaporator 3.
The refrigerant is vaporized and cools the indoor air, and the vaporized refrigerant is returned to the compressor 4 and compressed, thereby operating the cooling cycle.

The water vapor contained in the indoor air is cooled and liquefied in the evaporator 3, and flows down the surface of the evaporator 3 to the drain receiver 5' on the partition plate 5. Since the partition plate 5 is installed on a downward slope, the drain water flows through the drain receiver 5' and is sucked into the vaporizing wick 6.
spread within. Since the vaporizing wick 6 is installed from the upper surface of the drain receiver 5' to the inner surface of the frame 1 of the condenser 2, the drain water diffused into the vaporizing wick 6 touches the high temperature surface of the condenser 2, vaporizes, and condenses again. When the air heated to high temperature in the vessel 2 passes through the vaporizing wick 6, the drain water diffused in the vaporizing wick 6 is vaporized.

[Explanation of the idea]

By arranging each component within the frame 1 as described above, while the drain water liquefied in the evaporator 3 flows downward by gravity, the drain receiver 5'
The condensate is vaporized by the action of the vaporizing wick 6 and the condenser 2 located below the evaporator 3, and it is now possible to completely vaporize the drain while it flows down to the bottom plate of the frame 1. Therefore, there is no need to drain the drain water using a drain pipe, and the installation work is simplified.

In addition, when drain water is treated internally, there is no need for special parts such as pumps, and the vaporizing core 6 is attached using a vertical frame structure, which is a practical idea that can be manufactured at low cost. be.
