Indoor unit of air conditioner

Abstract

An indoor unit of an air conditioner comprises an intelligent sensor used for scanning activities of human bodies. The intelligent sensor consists of an intelligent eye component, a transmission part, a rotation driving motor, an expansion driving motor and a transmission gear, the intelligent eye component is provided with a sensor, the transmission part is provided with a rack, the intelligent eye component is connected with an output shaft of the rotation driving motor, the rotation driving motor is disposed on the transmission part, the rack is meshed with the transmission gear, and the transmission gear is connected with an output shaft of the expansion driving motor. The intelligent eye component consists of the sensor, a mounting part, a transmission disc and a sensing hood, a flat shaft hole is arranged in the transmission disc, the transmission disc is connected with the output shaft of the rotation driving motor by the flat shaft hole and connected with the mounting part, the sensor is disposed on the mounting part, the sensing hood is arranged on the mounting part, and the sensor is positioned between the sensing hood and the mounting part. The indoor unit of the air conditioner has the advantages that the indoor unit is simple and reasonable in structure, flexible in operation, low in manufacturing cost, easy in assembly and attractive in appearance.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an indoor unit of the air conditioner. Background technique [0002] With the development of science and technology, air conditioners and other household appliances tend to be more humanized and intelligent. And most air conditioners and other household electrical appliances in the market all need manual control. In response to this situation, some air conditioner manufacturers have made some improvements, such as Chinese Patent Document No. CN 201149330Y, which disclosed an air conditioner with a motion infrared sensor on November 12, 2008, including a motor, a transmission mechanism and an infrared sensor. For the sensor module, the motor is connected to the infrared sensor module through the transmission mechanism, and drives the infrared sensor module to reciprocate within a certain range. The transmission mechanism includes a driving gear and a driven gear; the motor is connected to t...

AI Technical Summary

Problems solved by technology

[0003] Due to the limitations of the structural design of the above smart sensors, the sensing range is greatly reduced, resulting in many sensing blind spots, and only after the human body enters the sensing area of ​​the smart sensor, the air conditioner can make some advance settings. Some good functions, usually in this case, it is easy to cause misjudgment or insensitivity, etc.

[0004] In addition, although the smart sensor can realize rotation sensing in a single small angle range, in principle, it can increase some sensing ranges, but this situation will cause the following two problems: 1) In order to ensure the appearance, basically it will be If the smart sensor is set inside the indoor unit of the air conditioner and close to its outer surface, the sensing range of the smart sensor in this state will also have some limitations and cannot play a good role; 2) in the air conditioner A certain part of the surface of the indoor unit protrudes to install the smart sensor. Although the sensing range of the smart sensor has been improved to a certain extent, it is difficult to coordinate with the overall appearance of the indoor unit of the air conditioner if the part of the smart sensor protrudes

[0005] In addition, according to the above two methods, the air conditioner indoor unit with smart sensor has only a single air outlet, because many smart sensors are set on the left end, right end or upper end of the air conditioner indoor unit. The asymmetric setting in space is difficult to perfectly combine with the air outlet, so that it is difficult to achieve precise intelligent sensing effect

However, there are also some very small air conditioner manufacturers who install an intelligent sensor at the left and right ends of the air conditioner indoor unit. Although the induction effect of the air conditioner indoor unit with this structure is more accurate, its production cost and The production time has increased a lot
