Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0041] It should be noted that if the present application embodiments involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0043] The air conditioner provided by the utility model can be an integrated air conditioner, a split air conditioner or a cabinet type air conditioner. Generally speaking, the cabinet type air conditioner is usually designed in a split type, that is, it comprises two parts of indoor unit and outdoor unit, which are separated from each other; however, the cabinet type air conditioner also exists in an integrated design. The integrated air conditioner is, for example, a window type air conditioner and a mobile air conditioner; if the air conditioner is a split air conditioner, it comprises two parts of indoor unit and outdoor unit.

[0044] Among them, the split air conditioner realizes refrigeration or heating through the circulation of refrigerant between the indoor unit and the outdoor unit, and the heat exchangers of the indoor unit and the outdoor unit are connected and communicated through copper pipes; since the connecting copper pipes between the indoor unit and the outdoor unit of the air conditioner need to be docked by lifting the indoor unit to create an operation space and a field of vision, two people usually cooperate to connect the copper pipes during after-sales installation, or a special supporting rod or other objects are prepared for support, which is time-consuming and laborious and has poor reliability. In order to solve this problem, the face frame is usually set as an upper face frame and a lower face frame which are detachably connected.

[0045] The existing connection mode of the upper face frame and the lower face frame usually adopts a single elastic arm type connector connection mode. During long-distance transportation, the single elastic arm type connector may be loose, resulting in the disconnection of the upper face frame and the lower face frame, and the disconnection of the lower face frame. Based on this, the utility model provides a face frame assembly and an air conditioner to reduce the probability of disconnection of the lower face frame. Of course, the face frame assembly can also be used on other devices.

[0074] Among them, indoor unit is mainly responsible for providing cool air or warm air to room, and the main components of indoor unit usually include indoor unit shell, first heat exchanger, filter screen and first control device, etc. The main role of indoor unit shell provides a stable frame for supporting the key components such as first heat exchanger, filter screen and first control device; refrigerant can absorb heat in the room in the first heat exchanger, so as to cool the air in the room, or, refrigerant can release heat in the first heat exchanger, so as to heat the air in the room; filter screen is used to filter dust and impurities in the air to keep the air clean. The first control device usually includes temperature sensor, control panel and remote controller, etc., the temperature sensor is used to monitor the temperature in the room and transmit information to the control system to adjust the operating state; the control panel and remote controller are used to set and adjust the working mode, temperature, air speed and other parameters of air conditioner.

[0075] Usually, indoor unit shell usually includes mounting plate, bottom disc face frame, air outlet frame, air deflector and panel, and mounting space and air duct for mounting other components are formed between mounting plate, bottom disc, face frame, air outlet frame, air deflector and panel.

[0076] Regarding mounting plate and bottom disc, mounting plate is the support base of the whole indoor unit structure, and is usually fixed on the wall surface or ceiling, which provides support and fixed position for the whole indoor unit. The mounting plate usually includes a plurality of mounting holes 101, which facilitates fixing the air conditioner on the wall surface or other mounting position by screws, and other structures are built on the basis thereof. The bottom disc is the frame part of the whole indoor unit, which is used to support and fix other components inside the air conditioner, such as second heat exchanger, fan, control system, etc. The bottom disc is installed on the mounting plate and is the support structure inside the air conditioner body, which is usually fixed on the mounting plate by screws or buckles 230.

[0077] As to the air outlet frame, the air deflector and the panel, the air outlet frame is the air outlet part of the indoor unit, which connects the fan and the air deflector of the indoor unit and controls the flow direction and speed of the air, and the shape and size of the air outlet frame will directly affect the air outlet effect of the air conditioner; the air outlet frame is usually installed at the front of the chassis face frame and connected with the air deflector, so that the air can be blown out in a specific direction. The air deflector is also called air duct plate, which guides the direction of air flow so that the cold or warm air can be evenly distributed to the indoor. The air deflector is usually adjustable so that the user can adjust the air direction to achieve better comfort effect; the air deflector is usually installed behind the air outlet frame and can be adjusted in angle to control the air flow direction, usually through hinges and other devices to make it adjustable. The panel is the appearance part of the indoor unit, which is usually the front cover of the air conditioner and directly contacts with the user. The design of the panel usually focuses on appearance and easy cleaning, and it also plays a role in protecting the internal components and preventing dust from entering. The panel is usually equipped with a display screen, buttons or sensors for the user to operate the air conditioner; the panel is installed at the front of the air outlet frame and the air deflector and is the outermost component covering the front of the entire indoor unit.

[0078] The outdoor unit is mainly responsible for releasing the heat absorbed from the indoor to the outdoor, and usually includes an outdoor unit shell, a compressor, a second heat exchanger, an expansion valve and a second control device; the compressor is the core component of the outdoor unit, which is responsible for compressing the refrigerant to increase the pressure and temperature of the refrigerant so that it can circulate. The refrigerant releases heat at the second heat exchanger and becomes a liquid state; alternatively, the refrigerant absorbs heat at the second heat exchanger; the expansion valve adjusts the flow and pressure of the refrigerant to reduce the temperature and pressure before entering the second heat exchanger; the second control device controls the operation of the outdoor unit and communicates with the indoor unit.

[0079] The heat exchangers of the indoor unit and the outdoor unit are connected by copper pipes or aluminum pipes, and the refrigerant circulates in them. In the cooling mode, the second heat exchanger of the indoor unit absorbs the heat in the room, and the refrigerant carries the heat to the second heat exchanger of the outdoor unit to release, so as to achieve the purpose of reducing the indoor temperature; in the heating mode, the refrigeration cycle is reversed, the second heat exchanger of the outdoor unit absorbs the heat outside, and carries it to the indoor unit to release, so as to increase the indoor temperature.

[0080] The above is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, any equivalent structural transformation made by using the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
