[0040] The air conditioner indoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figure 1-5 As shown, the air conditioner indoor unit 100 of the embodiment of the utility model includes a housing 1, a water tank 2 and a water pump assembly 3.

[0042] The housing 1 includes a front panel 11 and a casing 12. The casing 12 defines a mounting cavity 121 with one end open in a first direction. The front panel 11 is detachably connected to an open opening 122 of the casing 12. In other words, the front panel 11 is connected to the open end of the casing 12 so that the front panel 11 closes the mounting cavity 121. The front panel 11 is connected to the open end of the casing 12 by screws; or the front panel 11 is connected to the open end of the casing 12 by snapping.

[0043] The water receiving tank 2 is used to collect condensed water generated by the air conditioner indoor unit 100. The water receiving tank 2 is disposed in the installation cavity 121. The water receiving tank 2 includes an end portion 20 close to the open opening 122 in a first direction, and a limiting structure is disposed on the end portion 20.

[0044] The water pump assembly 3 includes a support frame 31 and a pump body 32. The support frame 31 includes a mounting portion 311 and a limiting portion 312. The limiting portion 312 can cooperate with the limiting structure to limit the water pump assembly 3 to the end 20. The pump body 32 is connected to the mounting portion 311, and the mounting portion 311 corresponds to the notch of the water receiving tank 2. The water suction port of the pump body 32 is located in the water receiving tank 2 so that the pump body 32 can suck water in the water receiving tank 2.

[0045] In other words, when the limiting portion 312 is in cooperation with the limiting structure, at least part of the pump body 32 installed on the installation portion 311 is located inside the water receiving tank 2, and the water suction port of the pump body 32 is located inside the water receiving tank 2, so that the pump body 32 can extract condensed water in the water receiving tank 2.

[0046] Compared with the related art, in the air conditioner indoor unit 100 of the utility model embodiment, the pump body 32 is directly installed on the end 20 of the water tank 2 through the support frame 31. On the one hand, the pump body 32 can be fixedly installed, so that the pump body 32 can normally suck the condensed water in the water tank 2, and the pump body 32 does not need to be connected to other parts, which is convenient for disassembling the water pump assembly 3. On the other hand, the end 20 of the water tank 2 is adjacent to the open port 122, so that the water pump assembly 3 can be disassembled and assembled at the open port 122, that is, after the front panel 11 is disassembled to open the open port 122, the operator can disassemble and assemble the water pump assembly 3 through the open port 122, thereby further improving the loading and unloading efficiency of the water pump assembly 3.

[0047] In order to make the present application easier to understand, the air conditioner indoor unit 100 of the present embodiment is further described below by taking the first direction being consistent with the front-rear direction and the second direction being consistent with the left-right direction as an example. The first direction is perpendicular to the second direction.

[0048] The air-conditioning indoor unit 100 of the present embodiment is an embedded air-conditioning indoor unit 100, that is, the air-conditioning indoor unit 100 is embedded in a furniture cabinet or a wall of an indoor area so that the air-conditioning indoor unit 100 is hidden in appearance, making the home layout more beautiful and achieving the purpose of improving the user experience.

[0049] In some embodiments, the air conditioner indoor unit 100 of this embodiment is embedded in the installation groove of the cabinet. The installation groove has an open end that is open to the front. When installing the embedded air conditioner indoor unit, the air conditioner indoor unit 100 is installed into the installation groove through the open end. The front panel 11 is located in front of the enclosure 12, and the front panel 11 has an air outlet 111 and an air inlet that are open to the front to ensure that the air outlet 111 and the air inlet can discharge and inlet air normally.

[0050] The water receiving tank 2 includes an end plate 24, a first side plate 25, and a second side plate 26. The first side plate 25 and the second side plate 26 are opposite to each other in the left-right direction, and the end plate 24 is connected to the first side plate 25 and the second side plate 26. The front end 20 of the first side plate 25, the end plate 24, and the front end 20 of the second side plate 26 form the end 20 of the water receiving tank 2.

[0051] In some embodiments, Figure 2-Figure 4 As shown, the limiting portion 312 includes a first section 3121 and a second section 3122. The rear end of the first section 3121 is connected to the mounting portion 311, and the upper end of the second section 3122 is connected to the front end of the first section 3121 and is bent toward the summer side. The second section 3122 is closer to the open mouth 122 relative to the first section 3121 in the front-to-back direction, that is, the second section 3122 is located at the front end of the first section 3121.

[0052] The limiting structure includes a first connector 21, which is disposed on the end surface of the end portion 20 adjacent to the open opening 122, that is, the first connector 21 is disposed on the front end surface of the end portion 20. A first limiting hole 31221 is disposed on the second section 3122, and the first connector 21 cooperates with the first limiting hole 31221 to prevent the pump body 32 from falling out of the water receiving tank 2. The first section 3121 contacts the top of the end portion 20, so that the water pump assembly 3 is limitedly disposed at the end portion 20, thereby improving the stability of the installation of the pump body 32.

[0053] In other words, the end plate 24, the front end 20 of the first side plate 25, the front end 20 of the second side plate 26 and the first connector 21 form a limiting structure. Among them, the front end 20 of the first side plate 25 and the front end 20 of the second side plate 26 support the first section 3121 to improve the stability of the installation of the pump body 32. The first connector 21 cooperates with the first limiting hole 31221 to limit the movement of the limiting part 312 in the up-down direction and the left-right direction, and the second section 3122 contacts the end plate 24 to limit the movement of the limiting part 312 to the rear. Thereby, not only the water pump assembly 3 is limitedly installed on the front end 20, but also the loading and unloading of the water pump assembly 3 is more convenient, and the loading and unloading efficiency of the water pump assembly 3 is further improved.

[0054] In some embodiments, the first connector 21 and the first limiting hole 31221 are interference fit, so that the movement of the water pump assembly 3 in the front and rear directions is limited by the first connector 21, which not only facilitates the loading and unloading of the water pump assembly 3, but also further improves the installation stability of the water pump assembly 3.

[0055] In other embodiments, the first limiting hole 31221 is threadedly matched with the first connector 21, wherein the first connector 21 is a screw and the first limiting hole 31221 is a threaded hole. The movement of the water pump assembly 3 in the front-to-back direction is limited by the first connector 21, which not only facilitates the loading and unloading of the water pump assembly 3, but also further improves the stability of the installation of the water pump assembly 3.

[0056] In some embodiments, Figure 2 and Figure 4 As shown, the limiting structure also includes a first limiting member 22, and the first limiting member 22 has a first limiting surface. The limiting portion 312 also includes a limiting member, and the first section 3121 has a second limiting surface 31214, and the second limiting surface 31214 is opposite to the first limiting surface in the front-to-back direction. The limiting portion 312 also includes a second limiting member 33, and the second limiting member 33 can be clamped and arranged between the first limiting surface and the second limiting surface 31214.

[0057] Specifically, the front end portion 20 of the water receiving tank 2 has a protrusion protruding upward, and the rear surface of the protrusion forms a first limiting surface.

[0058] After the limiting portion 312 is limitedly engaged with the front end portion 20 of the water receiving tank 2, the second limiting member 33 is clamped between the first limiting surface and the second limiting surface 31214. The first limiting surface and the second limiting surface 31214 are limited by the second limiting member 33, so that the support frame 31 cannot move in the front-to-back direction, thereby improving the installation stability of the water pump assembly 3.

[0059] When the water pump assembly 3 needs to be disassembled, the second limiting member 33 is removed from between the first limiting surface and the second limiting surface 31214, and the water pump assembly 3 can be moved forward so as to be removed from the front end portion 20 of the water receiving trough 2, thereby making the disassembly and assembly of the water pump assembly 3 more convenient.

[0060] In some embodiments, Figure 2 and Figure 4 As shown, the second stopper 33 also includes an extension portion 331 bent downward, and a second stopper hole 3311 is provided on the extension portion 331. A second connector 23 is provided on the front end portion 20 of the water receiving trough 2, and the second connector 23 cooperates with the second stopper hole 3311, so that the second stopper 33 is connected to the front end portion 20 of the water receiving trough 2 more stably.

[0061] In some embodiments, Figure 2 and Figure 4 As shown, the water pump assembly 3 further includes a float 34. The second stopper 33 is provided with a mounting through hole 332. The float 34 is inserted into the mounting through hole 332. In other words, the float 34 is mounted on the second stopper 33, so that the water pump assembly 3 can be easily disassembled and assembled at the open mouth 122, thereby improving the loading and unloading efficiency of the float 34 and facilitating the maintenance of the float 34.

[0062] Specifically, the second position-limiting member 33 has an escape opening, the front portion of which penetrates the front end surface of the second position-limiting member 33, and the rear portion of which penetrates the inner wall surface of the mounting through hole 332. The float 34 can be installed in the mounting through hole 332 through the escape opening, and the second position-limiting member 33 is clamped between the first position-limiting surface and the second position-limiting surface 31214, and the rear portion of the escape opening is closed by the second position-limiting surface 31214, so that the float 34 can move in the up-down direction and cannot escape from the escape opening. When the second position-limiting member 33 is removed from between the first position-limiting surface and the second position-limiting surface 31214, the float 34 can escape through the escape opening, thereby realizing the disassembly of the float 34.

[0063] In some embodiments, Figure 3 As shown, there are two second sections 3122, both of which are connected to the first section 3121, and the two second sections 3122 are spaced apart in the second direction. The first section 3121 has a notch 31211, and the notch 31211 is located between the two second sections 3122, and an escape space 3120 for escaping the first limiting member 22 is formed between the first section 3121 and the two second sections 3122.

[0064] In other words, when installing or disassembling the bracket, the support frame 31 needs to be placed on the water tank 2 and moved forward or backward, and the first limiting member 22 is avoided by the avoidance space 3120 to prevent the first limiting member 22 from affecting the movement of the limiting portion 312, thereby improving practicality.

[0065] In some embodiments, Figure 2 and Figure 3As shown, the limiting portion 312 also includes a third section 3123 and a fourth section 3124, and the third section 3123 and the fourth section 3124 are both connected to the first section 3121. The third section 3123 and the fourth section 3124 are spaced apart in the left-right direction, the third section 3123 is bent downward, and the third section 3123 is in contact with the first side plate 25. The fourth section 3124 is bent downward, and the fourth section 3124 is in contact with the second side plate 26, the second section 3122 is in contact with the end plate 24, and the first section 3121 is provided on the first side plate 25 and the second side plate 26. In other words, the water receiving trough 2 is located between the third section 3123 and the fourth section 3124, and the third section 3123 and the fourth section 3124 are in contact with the first side plate 25 and the second side plate 26 respectively, thereby limiting the movement of the support frame 31 in the left-right direction, thereby further improving the stability of the installation of the water pump assembly 3.

[0066] In some embodiments, Figure 2 and Figure 3 As shown, the first section 3121 includes a first plate body 31212 and a second plate body 31213, the first plate body 31212 is connected to the second plate body 31213, and the first plate body 31212 is adjacent to the open opening 122 relative to the second plate body 31213, the front end of the first plate body 31212 is connected to the upper end of the second section 3122, the front surface of the second plate body 31213 forms a second limiting surface 31214, and the mounting portion 311 is connected to the second plate body 31213. In other words, the mounting portion 311 is connected to the limiting portion 312 through the second plate body 31213, and the front surface formed by the second plate body 31213 forms the second limiting surface 31214, so that the overall structure of the support frame 31 is simpler and the redundancy of the structure is reduced.

[0067] The air conditioner of the embodiment of the utility model includes the air conditioner indoor unit 100 of any of the above-mentioned embodiments. The air conditioner of the embodiment of the utility model has the air conditioner indoor unit 100, and the pump body 32 installed in the air conditioner indoor unit 100 is directly installed on the end 20 of the water receiving tank 2 through the support frame 31. On the one hand, the fixed installation of the pump body 32 can be realized, so that the pump body 32 can normally suck the condensed water in the water receiving tank 2, and the pump body 32 does not need to be connected to other parts, which is convenient for disassembling the water pump assembly 3. On the other hand, the end 20 of the water receiving tank 2 is adjacent to the open port 122, so that the water pump assembly 3 can be disassembled and assembled at the open port 122, that is, after the front panel 11 is disassembled to open the open port 122, the operator can disassemble and assemble the water pump assembly 3 through the open port 122, thereby further improving the loading and unloading efficiency of the water pump assembly 3.
