[0046] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] Please refer to Figures 1 to 24 The present invention provides an air conditioner indoor unit, including an air inlet panel component 10, an evaporator assembly 20 and an air duct component 30. The evaporator assembly 20 and the air duct component 30 are both arranged on the inner side of the air inlet panel component 10. The evaporator assembly 20 includes: an evaporator body 28 and a refrigerant tube group 27. Along the circumference of the evaporator assembly 20, the evaporator body 28 has a first end body portion 281 and a second end body portion 282. The first end body portion 281 is connected to the refrigerant tube group 27, and the second end body portion 282 is connected to the air duct component 30; an evaporator bracket 21. The evaporator bracket 21 is installed on the air inlet panel component 10. A partition component 220 is provided on the evaporator bracket 21. A weight-reducing opening is provided on the portion of the partition component 220 located between the refrigerant tube group 27 and the air inlet panel component 10.

[0048] The air conditioner indoor unit of the present invention includes an air inlet panel assembly 10, an evaporator assembly 20, and an air duct assembly 30. The evaporator assembly 20 and the air duct assembly 30 are both disposed inside the air inlet panel assembly 10. The evaporator assembly 20 includes an evaporator body 28 and a refrigerant tube assembly 27. Along the circumference of the evaporator assembly 20, the evaporator body 28 has a first end portion 281 and a second end portion 282. The first end portion 281 is connected to the refrigerant tube assembly 27, and the second end portion 282 is connected to the air duct assembly 30. An evaporator bracket 21 is mounted on the air inlet panel assembly 10. The evaporator bracket 21 is provided with a partition member 220. A weight-reducing opening is provided in the portion of the partition member 220 located between the refrigerant tube assembly 27 and the air inlet panel assembly 10. This reduces the material used for the partition member, thereby reducing the production cost of the air conditioner.

[0049] In the embodiment of the present application, the partition component 220 is connected to the air inlet panel component 10 .

[0050] Specifically, the weight-reducing opening on the partition component 220 is a hollow structure, and the evaporator assembly 20 includes a sealing bowl 22, at least a portion of which is located above the water receiving tray component 40 and located at the first end portion 281 of the evaporator main body 28; the air conditioner indoor unit includes: a water receiving tray component 40, which is arranged below the evaporator assembly 20; a water receiving component 100, which is located in the weight-reducing opening so that the water receiving component 100 is connected to the air inlet panel component 10, and the water receiving component 100 is located at one end of the weight-reducing opening close to the sealing bowl 22 and above the sealing bowl 22, and the water receiving component 100 has a water receiving groove 101, and the water receiving groove 101 has a water receiving groove 102. A water receiving opening 102 is provided on the side wall of the air inlet panel assembly 10. Liquid on the inner surface of the air inlet panel assembly 10 flows into the water receiving groove 101, falls into the sealing bowl 22 through the water receiving opening 102, and then flows into the water receiving tray assembly 40. The present application further reduces the material used for the partition assembly by providing a hollowed-out weight-reducing opening in the partition assembly. A water receiving component is provided within the weight-reducing opening to collect condensed water generated by the refrigerant pipe assembly 27 on the air inlet panel assembly 10 through the water receiving component 100. This alleviates the problem of incomplete collection of condensed water caused by the weight-reducing opening in the partition assembly, which can lead to moisture and mildew inside the air conditioner. Since the connection between the partition assembly 220 and the air inlet panel assembly 10 does not need to be considered in terms of sealing quality, the assembly of the partition assembly is simplified.

[0051] Specifically, the air inlet panel component 10 includes: a positioning protrusion 11, the positioning protrusion 11 protrudes toward the evaporator assembly 20; a first end wall 110, the first end wall 110 is located at one end of the refrigerant tube group 27 away from the evaporator body 28, one end of the water receiving component 100 has a connecting protrusion 103 connected to the first end wall 110, and the other end of the water receiving component 100 has an insertion portion 104 for being inserted into the positioning protrusion 11; wherein, the water receiving component 100 is fixed to the air inlet panel component 10 by a first fastener 111 inserted into the connecting protrusion 103 and the first end wall 110.

[0052] The air inlet panel component 10 further includes a second end wall. The first end wall 110 and the second end wall are distributed at both ends of the air inlet panel component 10 along the circumference of the air inlet panel component 10 .

[0053] Specifically, the water receiving component 100 includes a water receiving body 105 and a guide portion 106 that are interconnected. The water receiving body 105 has a water receiving groove 101. The guide portion 106 extends toward a side away from the air inlet panel component 10 to form a guide groove 107. The guide groove 107 has a water receiving opening 102 at one end away from the water receiving groove 101. wherein, along the liquid flow direction in the guide groove 107, the distance between the bottom wall of the guide groove 107 and the sealing bowl 22 gradually decreases to buffer the condensed water, thereby preventing the condensed water from splashing.

[0054] Specifically, the condensed water generated by the cooling radiation of the refrigerant pipe group 27 of the evaporator assembly to the air inlet panel component 10 flows to the water receiving pan through the water receiving component 100 .

[0055] In the embodiment of the present application, the air conditioner indoor unit includes a water receiving pan component 40, which is arranged below the evaporator assembly 20; wherein the outer wall surface of the air duct component 30 is provided with a guide recess 31, which extends in the vertical direction and extends from one end of the air duct component 30 to the other end of the air duct component 30; the outer wall surface of the air duct component 30 is provided with a guide protrusion 32, which is located at the bottom of the guide recess 31 and inclined toward the water receiving pan component 40, and at least a portion of the guide recess 31 is located above the water receiving pan component 40, so that the liquid in the guide recess 31 flows into the water receiving pan component 40 through the guide protrusion 32. In this way, the condensed water generated inside the air conditioner indoor unit can be guided by the joint guiding effect of the guide recess and the guide protrusion to guide the condensed water generated in the air duct to the inside of the water receiving pan component 40, so that the condensed water is collected by the water receiving pan component 40 to prevent the air conditioner from being easily damp and mildewed.

[0056] Because the present invention utilizes the deflection recess 31 and the deflection protrusion 32 to collect condensed water generated at the top of the air duct component, it eliminates the need to rely on the insulation of foam to prevent condensation, thereby reducing the number of components within the air conditioner and simplifying assembly. Specifically, the evaporator assembly 20 is assembled onto the air inlet panel component 10, with the evaporator assembly 20 and the air inlet panel component 10 positioned together using pin holes and fastened with screws. The air duct component 30 is assembled onto the evaporator assembly 20, with the evaporator assembly 20 and the air duct component positioned together using pin holes and fastened with screws.

[0060] Specifically, the upper plate surface 321 has a first guide end, which is located at the end of the upper plate surface 321 away from the bottom plate portion 34, and the lower plate surface 322 has a second guide end, which is located at the end of the lower plate surface 322 away from the bottom plate portion 34. The first guide end and the second guide end are connected by a guide side edge; wherein, in the direction away from the bottom plate portion 34, the second guide end protrudes from the first guide end, so that the guide side edge is tilted so that after the condensed water passes through the guidance of the upper plate surface 321, the condensed water is further guided by the guide side edge to prevent the flow rate of the condensed water from being too high and causing the condensed water to splash out.

[0066] Optionally, the collecting hole 240 is opposite to the fin evaporator body of the evaporator assembly 20, so that the liquid falling from the collecting hole 240 flows onto the fins and is guided to the water collecting tray component 40 through the fins; and / or there are multiple collecting holes 240, and the multiple collecting holes 240 are arranged at intervals; and / or a collecting groove 241 is provided on the collecting tray 24, and the collecting groove 241 is connected to the collecting hole 240, and the free end of the collecting groove 241 extends toward the edge of the collecting tray 24.

[0067] Specifically, the weight-reducing opening extends from the edge of the partition component 220 to the first end portion 281 ; and / or the weight-reducing opening on the partition component 220 is in a long strip shape, and the weight-reducing opening extends along the length direction of the evaporator body 28 .

[0075] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0076] The air conditioner indoor unit of the present invention includes an air inlet panel assembly 10, an evaporator assembly 20, and an air duct assembly 30. The evaporator assembly 20 and the air duct assembly 30 are both disposed inside the air inlet panel assembly 10. The evaporator assembly 20 includes an evaporator body 28 and a refrigerant tube assembly 27. Along the circumference of the evaporator assembly 20, the evaporator body 28 has a first end portion 281 and a second end portion 282. The first end portion 281 is connected to the refrigerant tube assembly 27, and the second end portion 282 is connected to the air duct assembly 30. An evaporator bracket 21 is mounted on the air inlet panel assembly 10. The evaporator bracket 21 is provided with a partition member 220. A weight-reducing opening is provided in the portion of the partition member 220 located between the refrigerant tube assembly 27 and the air inlet panel assembly 10. This reduces the material used for the partition member, thereby reducing the production cost of the air conditioner.

[0077] Secondly, the present application provides a hollow structure for the weight-reducing opening and provides a water receiving member 100 for collecting water, further reducing the material used in the partition member. Furthermore, a water receiving member is provided within the weight-reducing opening to collect condensed water generated by the refrigerant tube assembly 27 on the air inlet panel member 10 through the water receiving member 100. This alleviates the problem of incomplete collection of condensed water inside the air conditioner due to the weight-reducing opening in the partition member, which can lead to moisture and mildew inside the air conditioner. Since the connection between the partition member 220 and the air inlet panel member 10 does not need to be considered in terms of sealing quality, the assembly of the partition member is simplified.

[0078] Again, the present application collects the condensed water generated on the top of the air duct component by setting a guide recess 31 and a guide protrusion 32. In this way, the generation of condensed water can be prevented without relying on the heat-insulating effect of the foam, thereby further reducing the number of components in the air conditioner and simplifying the assembly of components in the air conditioner.

[0079] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
