Detailed Description

The indoor unit of the air conditioner comprises a vertical indoor unit of the air conditioner and a hanging indoor unit of the air conditioner, wherein the vertical indoor unit of the air conditioner can be directly placed on the ground, and the hanging indoor unit of the air conditioner needs to be installed on a wall. The vertical air conditioner indoor unit comprises a tubular shell, an air inlet is formed in the back face of the shell, an air outlet is formed in the front face of the shell, an evaporator, a fan, an air duct mechanism and other internal mechanisms are arranged in the shell, and the evaporator is located between the air inlet and the fan. When the indoor unit of the air conditioner works, the fan rotates to form negative pressure inside the shell, so that indoor air enters the shell through the air inlet, contacts with the evaporator to exchange heat, and is discharged to the outside from the air outlet through the air duct mechanism, and the refrigerating or heating function is realized.

The evaporator and the air duct mechanism belong to one of core components of the air conditioner, and the evaporator is a heat exchanger. The operating principle of the air conditioner is understood as follows: the compressor compresses the gaseous refrigerant into a high-temperature high-pressure gaseous refrigerant, and then the gaseous refrigerant is sent to a condenser (an air conditioner outdoor unit) to be radiated to form a normal-temperature high-pressure liquid refrigerant, so that hot air is blown out of the air conditioner outdoor unit. The liquid refrigerant of normal temperature high pressure gets into the evaporimeter (air conditioning indoor set) through the capillary, because the refrigerant reaches the space behind the evaporimeter from the capillary and increases suddenly, pressure reduces, and liquid refrigerant will vaporize rapidly, becomes low temperature low pressure gaseous refrigerant to absorb a large amount of heats, the evaporimeter will become cold, the fan of air conditioning indoor set blows indoor air from the evaporimeter, and the air and the heat transfer temperature of evaporimeter reduce, so that air conditioning indoor set blows out cold wind. Meanwhile, water vapor in the air is condensed into water drops after meeting the cold evaporator and flows out along the water pipe, which is the reason that the air conditioner can discharge water. When heating, the four-way valve of the air conditioner can make the flowing direction of the refrigerant in the condenser and the evaporator opposite to that of the refrigerant when cooling, so that cold air is blown to the outdoor when heating, and hot air is blown to the indoor unit when heating.

And the quality of the tightness between the evaporator and the air duct mechanism directly influences the refrigeration or heating performance of the whole air conditioner, when the air conditioner refrigerates, if air directly enters the air duct mechanism without being cooled by the evaporator, condensate water can be formed on an electric heater in the air duct mechanism to influence the safety of electric appliances, therefore, the evaporator and the air duct mechanism are usually connected through a sealing structure, wherein the sealing structure comprises a wind shield, one side of the wind shield is connected with the evaporator, and the other side of the wind shield is connected with the air duct mechanism.

Among the prior art, all be equipped with the screw on evaporimeter and the wind channel mechanism, one side of deep bead passes through the screw respectively with evaporimeter and wind channel mechanism threaded connection, because wind channel mechanism is the working of plastics, under high temperature or low temperature environment, wind channel mechanism can warp because of expend with heat and contract with cold, lead to the screw on the deep bead and the unable accurate alignment simultaneously of screw on evaporimeter and the wind channel mechanism, thereby lead to the dismouting difficulty between deep bead and evaporimeter and the wind channel mechanism, user experience is poor.

In order to solve the above technical problem, an embodiment of the present invention provides an air conditioning indoor unit, which includes a wind deflector, an air duct mechanism, and a connector. The first side edge of the wind shield is provided with the limiting hole, the connecting piece penetrates through the limiting hole and is connected with the air channel mechanism, and a preset gap is formed between the outer surface of the connecting piece and the inner surface of the limiting hole, so that on one hand, when the connecting piece is connected with the wind shield and the air channel mechanism, the limiting hole and the hole for installing the connecting piece on the air channel mechanism are not strictly aligned, the machining precision of the limiting hole can be reduced, and the connection difficulty between the wind shield and the air channel mechanism can be reduced; on the other hand, the preset gap can reserve a corresponding gap for the deformation of the air duct mechanism caused by expansion with heat and contraction with cold in a high-temperature or low-temperature environment so as to adapt to the expansion with heat and contraction with cold of the air duct mechanism, and can effectively prevent the problem that the air duct mechanism is difficult to assemble and disassemble due to the deformation caused by expansion with heat and contraction with cold, thereby reducing the assembling and disassembling difficulty of the air duct and the air duct mechanism, reducing the assembling and disassembling time, saving the labor cost and improving the user experience; in another aspect, the size of the limiting hole is larger than the cross-sectional size of the connecting piece, so that the use of raw materials of the wind shield can be reduced, and the material cost is saved.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

By setting the preset gap, on one hand, when the wind shield 10 and the air duct mechanism 20 are connected by the connecting piece 40, the limiting hole 101 and the hole for installing the connecting piece 40 on the air duct mechanism 20 do not need to be strictly aligned, so that the processing precision of the limiting hole 101 can be reduced, and the connection difficulty between the wind shield 10 and the air duct mechanism 20 can be reduced; on the other hand, the preset gap can reserve a corresponding gap for the deformation of the air duct mechanism 20 caused by expansion with heat and contraction with cold in a high-temperature or low-temperature environment so as to adapt to the expansion with heat and contraction with cold of the air duct mechanism 20, and can effectively prevent the problem that the air deflector 10 is difficult to assemble and disassemble due to the deformation of the air duct mechanism 20 caused by expansion with heat and contraction with cold, thereby reducing the assembling and disassembling difficulty of the air deflector 10 and the air duct mechanism 20, reducing the assembling and disassembling time, saving the labor cost and improving the user experience; on the other hand, since the size of the limiting hole 101 is larger than the sectional size of the connecting member 40, the use of raw materials of the wind deflector 10 can be reduced, and the material cost can be saved.
