The wall-mounted air conditioner indoor unit 100 comprises a main body, a panel 20 movably mounted on the main body, and an electric control box assembly 15 mounted in the main body; the breaker 40 is connected between the electric control box assembly 15 and the power supply in series; the power cut-off switch 30 is electrically connected to the power cut-off device 40, and the power cut-off switch 30 is used for controlling the power cut-off device 40 to be powered off when the panel 20 is opened from the main body. Wherein, the panel is movably arranged on the main body means that the panel is movably connected with the main body so that the panel can be closed and opened. The panel can be rotatably connected with the main body, and the panel is opened in a rotating manner; or can be in sliding connection, and the panel is opened in a sliding way; or can be detachably connected, and the whole panel is detached from the main body; of course, the panel may be opened in other ways.

According to the technical scheme of the invention, the power-off switch 30 and the power breaker 40 are arranged on the main body, when the panel 20 is opened, the state of the power-off switch 30 is triggered to change, for example, the power-off switch 30 is changed from a closed state to an open state, of course, the power-off switch 30 can be changed from the open state to the closed state or other states, and the following description takes the case that the power-off switch 30 is changed from the closed state to the open state when the panel 20 is opened as an example; since the breaker 40 is electrically connected to the power-off switch 30, the breaker 40 disconnects the electrical control box assembly 15 from the power supply according to the state change of the power-off switch 30, so that the wall-mounted air conditioning indoor unit 100 is disconnected from the power supply. In this way, each component in the wall-mounted air conditioning indoor unit 100 is in a power-off state, and after the panel 20 is opened, the components of the air conditioning indoor unit are cleaned, overhauled and the like, so that electric shock is not caused, and the air conditioning indoor unit is safer after the panel 20 is opened. Accordingly, after the panel 20 is closed, the panel 20 may also trigger the state change of the power cut-off switch 30 when the panel 20 is closed, for example, the power cut-off switch 30 is changed from the open state to the closed state, and at this time, the power cut-off device 40 switches on the connection between the electronic control box assembly 15 and the power supply according to the state change of the power cut-off switch 30. In the invention, the connection circuit between the electric control box assembly 15 and the power supply is automatically disconnected when the panel 20 is opened; when the panel 20 is closed, the connecting circuit between the electric control box assembly 15 and the power supply is automatically communicated.

In this embodiment, the power cut-off switch 30 and the power cut-off device 40 are both installed on the main body, so that the connection wires between the power cut-off switch 30 and the power cut-off device 40, or the connection wires between the power cut-off device 40 and the electronic control box assembly 15 are spanned between the main body and the panel 20, and the movable opening of the panel 20 is prevented from being limited by one of the connection wires. However, the design is not limited thereto, and in other embodiments, the power cut switch 30 and the power cut device 40 may be both disposed on the panel 20; alternatively, one of the power cut-off switch 30 and the power cut-off 40 is provided on the panel 20, and the other is provided on the main body; or, the power-off switch 30 and the power-off device 40 are independent from the panel 20 and the main body, and are not installed on the panel 20 nor on the main body, as long as the power-off switch 30 is electrically connected with the power-off device 40, and the power-off device 40 is electrically connected with the electric control box assembly 15; the three mounting modes can also realize that the electric control box assembly 15 is in a disconnected state with the power supply when the panel 20 is opened; when the panel 20 is closed, the electric control box assembly 15 is communicated with the power supply. In the following description, the power cutoff switch 30 and the power cutoff unit 40 are provided in the main body as an example.

Preferably, in an embodiment of the present invention, the power cut-off switch 30 is a touch switch. Thus, when the panel 20 is closed, the touch switch is in contact with the panel 20, and the touch switch is in a connected state; when the panel 20 is opened, the touch switch is isolated from the panel 20, and the touch switch is in an off state, wherein the touch switch may be WP1-2S1-11-111 in this embodiment. By using a touch switch, the panel 20 can be made more sensitive to the activation of the touch switch when it is opened and closed. Here, the touch switch means that the touch switch can be turned on when the panel 20 is in contact with the touch switch, and the touch switch is turned off when the panel 20 is not in contact with the touch switch.

In another embodiment of the present invention, the power-off switch 30 is a resilient switch. When the panel 20 is closed, the panel 20 abuts against and presses the elastic switch, and when the panel 20 is completely closed, the elastic switch is in a pressed state, and at the moment, the elastic switch is in a communication state; when the panel 20 is opened, since the panel 20 is spaced apart from the elastic switch, the elastic switch is not pressed, and the elastic switch is in an off state. Elastic switch working property's stability is stronger, and the security is stronger, just can communicate by the state of being pressed, when opening panel 20 back washing or overhauls wall-hanging air conditioner indoor set, even can touch elastic switch occasionally, because the dynamics of this kind of touching is less, can not make elastic switch be in the state of pressing, makes elastic switch intercommunication, avoids the mistake to bump the accident that causes. In this embodiment, the elastic switch may be of a type KAN 3561. It should be noted that the elastic switch itself has a certain pressing stroke, and the panel 20 needs to apply a certain pressure to the elastic switch to make the elastic switch in an elastic compression state, and then the elastic switch is in a communication state; when the panel 20 is opened, the elastic switch is restored to a normal state (i.e., a non-pressed state), and the elastic switch is in an off state. It should be noted here that the distinction between the elastic switch and the touch switch in the previous embodiment is that the touch switch does not require the panel 20 to press it, and only needs to be in contact with it to trigger the touch switch; the elastic switch is triggered by pressing the panel 20.

When the panel is to be opened, the panel starts to be away from the proximity switch, and when the distance between the panel and the proximity switch is larger than the sensing distance, the proximity switch is converted into an off state. The proximity switch has the characteristics of long service life, good durability and the like. The proximity switch may be one of a vortex proximity switch, a capacitive proximity switch, a hall proximity switch. In the embodiment, the model of the proximity switch is IA2Q-P17, and other models of proximity switches are also possible.

Further, when the power-off switch 30 is a touch switch, the main body is provided with a mounting hole (not shown) for mounting the touch switch, and the panel 20 is correspondingly provided with a convex pillar (not shown) so that the convex pillar is inserted into the mounting hole to abut against the touch switch when the panel 20 is closed. Through set up the mounting hole in the main part, with touch switch installation in the mounting hole, set up the projection with mounting hole adaptation in panel 20 department of correspondence, when closing panel 20, the projection inserts in the mounting hole and contacts with touch switch, when opening panel 20, the projection is extracted from the mounting hole, keeps away from touch switch. Through the setting of above-mentioned mode, can effectively avoid opening panel 20 and wash or overhaul and touch the touch switch by mistake, certainly also can realize preventing the mistake through other settings and bump.

Further, when the power cutoff switch is a touch switch, the diameter range of the outer orifice of the mounting hole is preferably [5mm,10mm ]. The diameter of people's finger is generally more than 10mm, sets up in the within range that is less than or equal to 10mm through the diameter with the drill way in mounting hole, can effectively prevent the insertion of finger, improves the security. In addition, the outer orifice cannot be too small, which is not favorable for the insertion of the convex column. Here, the outer orifice refers to an orifice toward the side of the panel 20.

The mounting hole is arranged in a flared way. Like this, when panel 20 closed, the convex column on panel 20 can be played a guide effect to the pore wall of horn mouth form to set up the aperture in the hole that also can further reduce touch switch department like this, more effectual finger and touch switch's of avoiding touching.
