Abstract

PURPOSE:To make the cleaning of indoor air in a short time demonstrating a high dust-collecting efficiency when indoor air is contaminated by providing an open-close-plate with adjustability of the opening angle at an opening of a bypass provided in parallel with a main filter. CONSTITUTION:When indoor air is relatively clean, an open-close-plate 7 at an opening 6 of a bypass is opened so that, by increasing the quantity of air passing through the opening 6 of the bypass, the flow to a heat exchanger 8 is increased and the air-conditioning functions sufficiently. When indoor air is foul and the air-cleaning function needs to be augmented, the open-close-plate 7 is turned to a closure and the air sucked into the opening 6 of the bypass is reduced in quantity. Then an increase in pressure loss occurs and the air sucked in somewhat decreases in quantity, but since the quantity of the air passing through a main filter 4 increases in ratio, the degree of cleanness of the air ejected through an air outlet 9 can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner equipped with an air purifying device that has an air purifying function for collecting dust and the like.

BACKGROUND OF THE INVENTION In recent years, as concerns about health have increased, there has been a demand for air conditioners with an air purifying function that cleans dust such as cigarette smoke that contaminates indoor rooms.

A conventional air conditioner equipped with an air purifier has a configuration as shown in FIG. That is, an air suction port 2 is provided on the front surface of the main body 1 of the air conditioner, and a pre-filter 3 is provided on the air suction port 2 to collect relatively large dirt and dust. A main filter 4 is installed to charge dust-containing air and collect dust. Behind the prefill 3 and on either side of the main filter 4, bypass openings 16 are provided. A blower 6 and a heat exchanger 7 for heat exchange are arranged behind the pre-filter 3, main filter 4, and bypass opening 1e, and are configured to discharge air into the room through an air outlet 8.

The operation of the air conditioner with air purifier configured as above will be described below.

Dust-containing air inside the room is taken into the main body 1 through the air suction port 2. The dust-containing air taken in is passed through the pre-filter 3.
Large particles such as dirt and dust are collected by the main filter 4, while small particles such as cigarette smoke are purified by the main filter 4. Further, air that does not pass through the main filter 4 passes through the bypass opening 1e, and together with the purified air, the air blower 6. It passes through the heat exchanger 8 and is discharged into the room through the air outlet. Here, the main filter 4 is of an electrostatic precipitator type, and the dust-containing air is charged with a high voltage, and then the dust is collected by a dust collecting filter.

Although not shown, cold water, refrigerant, or hot water is circulated in a separate system in the heat exchanger 8, and when the indoor air taken into the main body 1 passes through the heat exchanger 8, it is heat exchanged and becomes cold air or hot water. Warm air is blown into the multiple rooms through the air outlet 9.

As mentioned above, the bypass opening 1e is provided because if a main filter is installed at the air suction port 2, the pressure loss on the suction port side will be extremely large when used as an air conditioner. This is to prevent the performance of the air conditioner from deteriorating, such as deterioration of the air conditioner's performance.

Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, only a part of the indoor air taken in through the air intake port is passed through the main filter, which makes it difficult to clean the air blown out through the air outlet. However, if the indoor air is very polluted, it takes time to purify the indoor air.

The present invention solves the above-mentioned conventional problems, and allows the pressure loss on the suction port side to be kept as low as possible during normal use, and the air cleaning function can be easily increased as needed. The purpose is to provide a harmonizer.

Means for Solving the Problems To achieve this object, the air conditioner with an air purifier of the present invention has an air inlet opening at the front of the main body, and a pre-filter disposed on the entire surface of the air inlet. , prefi μ
a main filter that collects extremely small particles that have passed through the filter, a bypass opening provided behind the pre-filter in parallel with the main filter, and a blower and heat exchanger arranged behind the pre-filter and the main filter. The bypass opening has a configuration in which an opening/closing plate with a variable rotation angle is disposed in the bypass opening.

If the indoor air is extremely polluted due to the configuration of the main filter, the opening/closing plate can be operated to reduce the amount of air sucked into the bypass opening and increase the amount of air passing through the main filter. The cleanliness of the air blown out from the air outlet can be increased, and indoor air can be purified in a short time. In addition, when used in relatively clean indoor air, the air conditioner can be used as an air conditioner by operating the opening/closing plate to increase the amount of air passing through the bypass opening, thereby minimizing the pressure loss on the suction port side. be able to.

EXAMPLE An example of the present invention will be described below with reference to FIG. Among them, those having the same configuration as the conventional example are given the same numbers and detailed explanations will be omitted.

As shown in the figure, an air inlet 2 is provided on the front side of the main body 1 of the air conditioner, a pre-filter 3 is provided in the air inlet 2, and a main filter 4 and a bypass opening 6 are provided behind the pre-filter 3. ing. The bypass opening 6 is provided in a position parallel to the main filter 4. The bypass opening 6 is provided with an opening/closing plate 7 whose rotation angle is variable to adjust the amount of air passing through. The pre-filter 3. Main filter 4. A blower 6 and a heat exchanger 8 for heat exchange are arranged behind the bypass opening 6 and discharge air into the room from an air outlet 9.

The operation of the air conditioner with air purifier of this embodiment configured as described above will be explained below.

First, if the indoor air is relatively clean, open the opening/closing plate 7 of the bypass opening 6 to increase the amount of air in the bypass opening 6, increase the flow rate to the heat exchanger 8, and ensure the function as an air conditioner is sufficient. Make sure you can demonstrate your abilities.

Next, when the indoor air is very dirty and the air purification function is to be improved, the opening/closing plate 7 is rotated in the closing direction to reduce the amount of air sucked into the bypass opening.

At this time, the pressure loss increases and the amount of intake air decreases slightly, but the ratio of the amount of air passing through the main filter 4 increases, so the cleanliness of the air blown out through the air outlet 9 can be increased.

As described above, according to the present embodiment, by providing the opening/closing plate with a variable rotation angle in the bypass opening 6, the opening/closing angle of the opening/closing plate can be adjusted to the X node according to the indoor air pollution condition. By changing the ratio of the amount of air passing through the room, the air purification function can be improved, and indoor air can be purified in a short time.

In this embodiment, the main filter is an electrostatic precipitator that collects dust by charging dust-containing air, but the main filter may be a filter-type dust collecting filter that collects dust.

Effects of the Invention As described above, the present invention has an opening/closing plate with a variable opening/closing angle arranged in the bypass opening provided in parallel with the main filter, thereby reducing the amount of intake air passing through one main filter and the amount of air passing through the bypass opening. Excellent air that can adjust the ratio of intake air volume, exhibits high dust collection efficiency even when indoor air is polluted, and can purify indoor air in a short time. This makes it possible to realize an air conditioner with a purifier.
