Problems solved by technology

[0004] The problem in the air conditioner provided with the air supply and exhaust device described in the above-mentioned Patent Document 1 is that the operation is troublesome because the indoor personnel need to operate the operating device to perform the forced exhaust operation when they feel the air pollution.
Therefore, it can be considered that the range of fluctuations in the indoor air pollution state increases, especially when performing redundant exhaust operation, since the indoor air whose temperature and humidity have been adjusted by the air conditioner is discharged to the outside, the air conditioner's operating costs are increased. load, this part of the operating energy is lost
[0006] In addition, when the exhaust operation is performed, the air in the room is exhausted, and the exhausted part of the air can be replenished from anywhere, but there is a problem that, for example, when replenishing from an adjacent room , if the air in the adjacent room is already polluted, the pollution status of the air in this room cannot be changed

Embodiment Construction

[0042] This embodiment relates to an air conditioner capable of air supply operation and exhaust operation.

[0043] Hereinafter, each Example of the air conditioner of this application is demonstrated using drawing.

[0044] The overall structure of the air conditioner will be described using FIGS. 1 to 4. FIG. 1 is an external view of the indoor unit of the air conditioner of the present invention. FIG. 2 is an external view of the indoor unit in FIG. 1 with the decorative cover removed. FIG. 3 It is the A-A sectional view of FIG. 1, and FIG. 4 is the B-B sectional view of FIG. 1.

[0045] The indoor unit 1 is composed of a cabinet 2, a decorative cover 3, and a front cover 4. Up and down the indoor unit 1 are provided with an air intake port 5 for sucking indoor air to be adjusted in temperature and humidity and an air delivery port 6 for sending out indoor air with adjusted temperature and humidity. The air outlet 6 is provided laterally in the longitudinal direction of ...

Abstract

The object of invention is to solve the problem that air conditioners provided with a mechanism which enables air discharge of discharging indoor air and air supply of introducing outdoor air are inconvenient since a user must allow the air conditioners to perform air discharge operation using an operation button when the user feels the pollution of indoor air. An air conditioner comprises an air pollution sensor, and is configured to allow an air supply / discharge device to perform air discharge operation when this sensor detects the pollution of air. The air conditioner is also configured to allow the supply / discharge device to perform air supply operation for a predetermined time after the air discharge operation to introduce fresh air into a room so that the polluted air is attenuated.

Description

technical field [0001] The present invention relates to an air conditioner capable of air supply operation and exhaust operation. Background technique [0002] Since the split-type air conditioner connects the indoor unit and the outdoor unit with a connecting pipe passing through the wall, it is difficult to manage air pollution in a living room where the indoor unit is installed. Therefore, it was tested to install an air purification filter in the indoor unit and use the air blowing from the indoor blower to maintain the cleanliness of the indoor air. [0003] In addition, recently, as shown in Japanese Patent Application Laid-Open No. 2000-274727 (Patent Document 1), it has been proposed to install an air supply and exhaust device in the indoor unit of the split type air conditioner. The channels for the connecting pipes are used to ensure the ventilation channels, and the air supply for introducing the outdoor air into the room and the exhaust for exhausting the indoor...
