Description

Air conditioner with bactericidal function

technical field

The utility model relates to an air conditioner, in particular to an air conditioner with a sterilization function.

Background technique

As we all know, air conditioners have cooling and heating functions, which can create a comfortable indoor environment for users.

In recent years, an air conditioner with cooling, heating and air purification functions has appeared on the market, which can create a comfortable and fresh indoor environment for users.

As shown in Figure 1 and Figure 2, the structure of the existing air conditioner is generally: the lower part of the front of the casing 1 is provided with a suction grille 2 for sucking indoor air; Exhaust port 3 for exchanged and purified air.

The inside of the housing 1 is provided with an air supply device 7 for forced circulation of indoor air; a heat exchanger 6 is provided below the air supply device 7 .

An air filter 4 for filtering relatively large foreign objects is arranged behind the air suction grille 2 ; a dust collecting device 5 is arranged behind the air filter 4 .

When the air conditioner works in a cooling mode, the air intake grille 2 can ionize the inflowing air, and the ionized dust is collected by the dust collecting device 5, and the ionized air contains a large amount of negative oxygen ions, and the ionized dust is collected by the heat exchange After the device 6, it is discharged into the room through the exhaust port 3, and the negative oxygen ions make the indoor air fresh and pleasant.

If the above-mentioned existing air conditioner does not drive the heat exchanger 6, it can be used as an air cleaner.

If an electric heater is set in the shell 1 of above-mentioned existing air conditioner, then can make it increase a heating function.

But above-mentioned existing air-conditioner has following shortcoming: whole air-conditioner uses a blower device 7, and its refrigerating air flow path and clean air flow path are identical, so when not performing wherein certain function, heat exchanger 6 or The dust collection device 5 will hinder the flow of air, thereby increasing energy consumption, and when the heat exchanger or the air supply device is polluted, its air purification function will be greatly reduced.

In addition, because the air conditioner does not have a sterilizing device, the indoor air is constantly circulating, and the bacteria in the air will accumulate more and more, which is not conducive to the people who live and work indoors.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the above-mentioned shortcomings of the existing air conditioner and provide an air conditioner with a bactericidal function that can kill bacteria in the air and reduce energy consumption.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: the utility model has an air conditioner with a sterilizing function, comprising: a shell, a heat exchanger, a first air inlet, a first air outlet, and an air supply device; The air purification chamber on the upper part of the inner cavity of the shell; the second air inlet and the second exhaust port arranged in the front middle part of the outer shell; the air forced circulation fan arranged inside the second exhaust port; the air arranged around the fan The guiding device; the dust collecting device arranged inside the second air suction port; the dust collecting device arranged inside the second air suction port; and the sterilizing device arranged between the second air suction port and the dust collecting device.

The sterilizing device is an ultraviolet lamp.

The outer surface of the dust collecting device is coated with a photocatalyst coating.

The outer surface of the fan (55) is coated with a photocatalyst coating.

The outer surface of the heat exchanger (54) is coated with a photocatalyst coating.

The photocatalyst overcoating is titanium dioxide coating.

A shading plate that can prevent ultraviolet rays from leaking into the room is arranged above the second air inlet.

The beneficial effects of the utility model are: the cooling and heating air flow paths are separated from the purification air flow paths, reducing energy consumption; the sterilizing device and the photocatalyst coating can completely kill bacteria in the air and eliminate peculiar smells in the air .

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figure 3, the air conditioner with sterilizing function of the present embodiment includes: a casing 51, a heat exchanger 54 and an air supply device 55; an air cleaning chamber C formed on the upper part of the casing 51; The second air inlet 51c and the second air outlet 51d in the middle of the front; the air forced circulation fan arranged inside the second air outlet 51d; the air guiding device 59 arranged around the fan 55; The dust collecting device 56 inside the port 51; the dust collecting device 56 provided inside the second suction port 51c; and the ultraviolet lamp 58 provided between the second suction port 51c and the dust collecting device 56.

Inside the casing 51, the air cleaning chamber C is separated from the refrigerating and heating air flow path A and the clean air flow path B.

The outer surface of the dust collecting device 56 is coated with a titanium dioxide coating 57 .

The outer surface of the fan 55 is coated with titanium dioxide coating.

The outer surface of the heat exchanger 54 is coated with titanium dioxide coating.

A shading plate 60 that can prevent ultraviolet rays from leaking into the room is arranged above the second air inlet 51c.

The working process of the air conditioner with bactericidal function of the present embodiment is described below:

When the air conditioner is energized and works in the cooling mode, the indoor air enters the air conditioner through the first air inlet 51a on the casing 51 under the drive of the air supply device 53, and is connected with the heat exchanger 54 when flowing through the cooling air flow path A. The heat is exchanged to become cold air, and then discharged into the room through the first exhaust port 51b, thereby cooling the indoor environment.

At the same time, under the drive of the fan 55, the indoor air flows into the air cleaning chamber C through the second air inlet 51c. Under the irradiation of the ultraviolet lamp 58, the bacteria in the air are killed, and at the same time, the peculiar smell in the air is eliminated by titanium dioxide. The photocatalyst overcoat 57 decomposes, then, the air that is sterilized and deodorized flows through the dust collection device 56, and dust and foreign matter are collected in the dust collection device 56, and the clean air is discharged to the room through the second exhaust port 51d, thereby Indoor air plays a role in thorough purification.

Of course, according to the user's needs, the air purification and sterilization operations can be performed simultaneously with the cooling or heating operation, or can be performed separately.
