Detailed Description

The present invention is specifically described below by way of exemplary embodiments. It should be understood, however, that elements, structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.

An air conditioner indoor unit according to an embodiment of the present invention will be described with reference to fig. 1 to 23. The indoor unit of the air conditioner can be in a cabinet type, can also be in an on-hook type and the like. In the following description, an indoor unit of an air conditioner will be described as an example of a cabinet air conditioner.

The air-conditioning indoor unit comprises:

the housing 1 may be substantially cylindrical, and the housing 1 is formed with an air inlet and an air outlet. The air inlet is generally disposed at the rear side or the left and right sides of the housing 1, and the air outlet is disposed at the front side of the housing 1.

The shape of the housing 1 may also be an elliptic cylinder or a square cylinder; the front side is the side of the air-conditioning indoor unit facing the user when in use, and the opposite side is the rear side.

An air duct formed by a volute is arranged in the shell 1, a heat exchanger is arranged between the air inlet and the air duct, indoor air passes through the air duct after heat exchange of the heat exchanger by the air inlet, and circulates to the indoor from the air outlet, so that the refrigerating/heating function of the air conditioner is realized.

The door plate 2 is connected to the air outlet of the shell 1 in a sliding mode, and the air outlet can be opened or closed through the movement of the door plate 2 relative to the shell 1; for example, as shown in fig. 1, the two door panels 2 are provided, and in order to provide a split door, the outlet is closed when the two door panels 2 are moved close to each other, and the outlet is opened when the two door panels 2 are moved away from each other. It should be noted that, the door panel 2 may also be single, and when a single door panel 2 moves to block the air outlet, the air outlet is closed, and when a single door panel 2 moves to expose the air outlet, the air outlet is opened.

The movement of the door panel 2 is driven by a motor, the gear and rack transmission is realized, and a controller in the indoor unit of the air conditioner controls the rotation of the motor, so that the movement of the door panel 2 is controlled. When the air conditioner operates, the controller controls the door panel 2 to open the air outlet; when the air conditioner is out of work, the controller controls the door panel 2 to close the air outlet.

Sensing unit 3, as shown in fig. 7, including automatically controlled board 31 and infrared sensor 32, infrared sensor 32 installs on automatically controlled board 31, sensing unit 3 and controller electric connection, the controller is according to the motion of sensing unit 3 received signal's change control door plant 2, infrared sensor 32 has transmitting head 321 and receiving head 322, transmitting head 321 outwards launches the signal and forms the transmitting area, receiving head 322 received signal forms the receiving area, transmitting head 321 outwards launches infrared signal and reflects back to receiving head 322 department when meetting the material and block.

According to the air-conditioning indoor unit of the utility model, the door plate 2 is made of non-light-transmitting material, the light-transmitting area is arranged on the door plate 2, the light-transmitting area can be formed by arranging the light-transmitting holes 21 on the door plate 2, and the sensing unit 3 is arranged behind the light-transmitting area of the door plate 2; the transmitting head 321 and the receiving head 322 on the infrared sensor 32 correspond to the light-transmitting hole 21, and can transmit and receive signals through the light-transmitting hole 21.

The description will be given by taking the door panel 2 in the closed state and needing to be opened as an example: when the light-transmitting area is shielded, the signal emitted by the sensing unit 3 is sent by the emitting head 321 and reflected back to the receiving head 322 from the shielded position, the received signal and the light-transmitting area are changed when not shielded, and the door panel 2 moves to open the air outlet;

in addition, the shielding time can be designed, and when the signal change time reaches the shielding time required by the opening of the door panel 2, the door panel 2 is opened; when the light-transmitting area does not receive shielding or the shielding time does not reach the time required by opening the door panel 2, the door panel 2 is not opened. For example, the shielding time required for opening the door panel 2 is 3s, and when the user shields the light-transmitting area for 3s, the door panel 2 is opened; when the user blocks the light transmission region for 3 seconds, the door panel 2 does not move.

Similarly, when the door panel 2 is in the open state and needs to be closed, the light-transmitting area is shielded for 3 seconds, and the air outlet is closed by the door panel 2.

In this air conditioning indoor set, can start the motion of door plant 2 and opening of air conditioner operation through the operation of sheltering from to the light transmission zone on door plant 2. The light-transmitting area is the switch key area, the user can cover the switch key area with fingers or a palm to start the movement of the door plate 2 and start and stop of the air conditioner, the operation is extremely convenient, and even if an object in the hand is inconvenient to use, the switch key area can be shielded by the object.

It should be noted that only the operation of blocking the light transmission region may be used as the operation of starting the opening and closing of the door panel 2, that is, the operation of blocking the light transmission region only drives the door panel 2 to open or close, and the operation of the air conditioner is not controlled.
