Figures 1-2 However, there is great limitation in positioning the installation position of the seal sponge using the stretch protruding rib, for example, most of the surface of the stretch protruding rib is circular arc, and the remaining part of the surface is plane, but it is inclined and has small area, thereby causing the under-positioning of the seal sponge on the stretch protruding rib, and further causing the paste of the seal sponge on the stretch protruding rib to be prone to uneven and unstable, etc., so that the indoor side assembly gap between the air conditioner main body and the outer box cannot be reliably sealed.

[0040] The indoor unit of the air conditioner according to the embodiments of the utility model is described below with reference to the drawings.

[0041] As Figures 1-11 shown, the wall-penetrating air conditioner according to the embodiments of the utility model comprises an air conditioner main machine and an outer box body 100, and the outer box body 100 has an open end 110 with an indoor side opening 130. The open end 110 of the outer box body 100 is open on the indoor side of the building. The open end has the indoor side opening 130. The air conditioner main machine comprises a bottom plate 200 which is attached to the upper side of the lower box wall 121 of the outer box body 100, and the bottom plate 200 has an indoor part which is exposed from the indoor side opening 130 of the outer box body 100.

[0042] That is, a part of the bottom plate 200 is arranged in the outer box body 100 through the open end 110, and the other part of the bottom plate 200 is exposed from the outer box body 100 and extends into the indoor side, and the other part of the bottom plate 200 is the indoor part. The indoor part is used for mounting a heat exchange assembly which can exchange heat with the indoor environment.

[0043] The air conditioner main machine further comprises a support 300 and a sealing material.

[0044] The support 300 is connected to the lower side of the bottom plate 200, and the end face of the open end 110 comprises a first limiting face 124 which is located below the indoor side opening 130, and the support 300 has a matching face 340 which faces the first limiting face 124 and is spaced apart from the first limiting face 124, and the matching face 340 is perpendicular to the extension plane of the bottom plate 200.

[0045] The sealing material comprises a first sealing strip 410 which is attached to the matching face 340, and the first sealing strip 410 is abutted between the support 300 and the first limiting face 124 to facilitate the lower side matching gap 501 between the air conditioner main machine and the outer box body 100 to be sealed from the front side.

[0046] When the bottom plate 200 is installed into the outer box body 100, the first sealing strip 410 covers the lower side matching gap 501 between the air conditioner main machine and the outer box body 100, so as to prevent the outdoor air from entering the indoor area through the lower side matching gap 501 between the air conditioner main machine and the outer box body 100.

[0047] like Figure 1 and Figure 2 As shown, the through-wall air conditioner in the related technology includes an air conditioner body and an outer casing 600 to which it is attached. The outer casing 600 opens to the indoor side, and the indoor side portion of the air conditioner body is exposed through the indoor side opening of the outer casing. A sealing sponge 800 is connected to the indoor side portion of the air conditioner body, surrounding the upper side of the top cover bracket, the outer side of the middle partitions on both sides, and the lower side of the bottom chassis 700. Tensile ribs 710 stamped on the chassis 700 connect to the sealing sponge 800.

[0048] Compared with related technologies, the wall-mounted air conditioner of this utility model directly installs a support member 300 on the lower side of the chassis 200, connecting the first sealing strip 410 of the sealing air conditioning unit and the outer casing 100 to the support member 300, replacing the connection of the sealing strip to the tensile rib stamped on the chassis in related technologies. Since the support member 300 is separately installed on the lower side of the chassis 200 and is not a structure stamped on the chassis 200, the support member 300 does not need to be constructed with a large arc surface, allowing the mating surface 340 of the support member to be constructed perpendicular to the extended plane of the chassis. On the one hand, the mating surface 340 is flat, increasing the contact area between the mating surface 340 and the first sealing strip, allowing a larger portion or all of the first sealing strip 410 to be evenly adhered to the mating surface 340, resulting in more uniform adhesive force on each part of the first sealing strip 410. Furthermore, the mating surface 340 is not only flat, but also extends in a direction perpendicular to the chassis 200, so that the first sealing strip 410 can be evenly abutted between the mating surface 340 and the first limiting surface 124. Thus, the mating surface has a better positioning effect on the first sealing strip 410, thereby improving the sealing effect between the air conditioning unit and the outer casing 100.

[0049] Alternatively, the sealing structure can be made of PVC foam; the sealing structure can be made of EVA foam; the sealing structure can also be made of other sealing materials.

[0050] To make this application easier to understand, the following describes the through-wall air conditioner of this utility model embodiment, taking as an example that the horizontal and left-right directions are consistent and the open end 110 of the outer casing 100 is located on the front side of the outer casing 100.

[0051] Among them, such as Figure 2 As shown, the outer casing 100 includes a lower casing wall 121, a left casing wall 122, and a right casing wall 123. The front side of the lower casing wall 121 has a lower edge 131, and a lower side fitting gap 501 is formed between the lower edge 131 and the lower side of the chassis 200, the lower side fitting gap 501 extending in the left-right direction. The front side of the lower casing wall 121 forms a first limiting surface 124.

[0052] The chassis 200 comprises a first side and a second side opposite in the left-right direction, and the first side is located left of the second side. The front side of the left cabinet wall 122 and the front side of the right cabinet wall 123 each have a side edge 132, and the side edge 132 of the left cabinet wall 122 and the side edge 132 of the right cabinet wall 123 form left and right matching gaps 502 and 503 with the two sides of the chassis 200, respectively. The end face of the open end 110 further comprises a second limiting face 125 and a third limiting face 126 opposite in the left-right direction, and the indoor side opening 130 is located between the second limiting face 125 and the third limiting face 126 in the left-right direction. The front side of the left cabinet wall 122 forms the second limiting face 125, and the front side of the right cabinet wall 123 forms the third limiting face 126.

[0053] In some embodiments, as shown in Figures 3-5 The support 300 comprises a first wall plate 320 and a second wall plate 330, the first wall plate 320 is perpendicular to the extension plane of the chassis 200, and the matching face 340 is located in the front side of the first wall plate 320. The second wall plate 330 is bent from the bottom of the first wall plate 320 to the front side edge of the lower cabinet wall 121, and is supported on the lower side of the first sealing strip 410.

[0054] Specifically, the support 300 further comprises a second wall plate 330 connected to the lower end of the first wall plate 320, and the second wall plate 330 is bent towards the side close to the open end 110. The chassis 200, the first wall plate 320 and the second wall plate 330 define a mounting groove, and at least part of the first sealing strip 410 is arranged in the mounting groove. That is, the second wall plate 330 is located at the lower end of the first sealing strip 410, and the second wall plate 330 can limit the downward movement of the first sealing strip 410. When the first sealing strip 410 is not pressed tightly on the lower cabinet wall 121 of the open end 110 by the first wall plate 320, the first sealing strip 410 can be in contact with the second wall plate 330 or not.

[0055] When the chassis 200 is installed in the outer cabinet 100, and the first sealing strip 410 is pressed tightly on the lower cabinet wall 121 by the first wall plate 320, the first sealing strip 410 will be deformed and tend to move downwardly due to extrusion. By supporting the first sealing strip 410 with the second wall plate 330, the loosening of the connection between the first sealing strip 410 and the first wall plate 320 due to deformation or pressure after the first sealing strip 410 is pressed can be avoided, thereby ensuring the sealing effect of the first sealing strip 410.

[0056] In addition, when the first sealing strip 410 is installed on the first wall plate 320, the first sealing strip 410 can be limited by the limiting of the second wall plate 330 due to the large length dimension of the first sealing strip 410, thereby reducing the installation difficulty of the first sealing strip 410 and improving the installation efficiency of the first sealing strip 410.

[0057] At least part of the first sealing strip 410 abuts between the lower cabinet wall 121 and the first wall plate 320, and the end of the second wall plate 330 close to the lower cabinet wall 121 is spaced apart from the lower cabinet wall 121, thereby avoiding the second wall plate 330 from blocking the contact of the first sealing strip 410 with the lower cabinet wall 121.

[0058] In some embodiments, the first sealing strip 410 is rectangular, and the forward projection of the first sealing strip 410 completely falls within the range of the fitting surface 340. That is, the first sealing strip 410 is entirely pasted in the fitting surface 340, thereby further improving the stability of the pasting of the first sealing strip 410 with the fitting surface 340 and the positioning effect of the fitting surface 340 on the first sealing strip 410.

[0059] In some embodiments, as shown in Figures 3-5 The support 300 further includes a mounting plate 310 connected to the lower side of the chassis 200. The mounting plate 310 is connected to the upper end of the first wall plate 320, and the mounting plate 310 is located at the front side of the first wall plate 320. That is, the support 300 is connected to the lower side of the chassis 200 through the mounting plate 310, and since the mounting plate 310 is located at the front side of the first wall plate 320, when the chassis 200 is installed in the outer cabinet 100, the lower cabinet wall 121 of the outer cabinet 100 is not blocked by the mounting plate 310, facilitating the installation of the outer cabinet 100 and the chassis 200.

[0060] Optionally, the mounting plate 310 of the support 300 can be fixed to the lower surface 210 of the chassis 200 by welding; or the mounting plate 310 of the support 300 can also be screw-fixedly connected to the lower surface 210 of the chassis 200.

[0061] The support 300 further has an end portion exposed from the first side portion and / or the second side portion, and the end portion has a third wall plate 342 with a rear side surface coplanar with the fitting surface 340.

[0062] That is, the support 300 further has a left end portion exposed from the left side of the chassis 200, and the left end portion has a third wall plate 342 with a rear side surface coplanar with the mating surface 340. Alternatively, the support 300 further has a right end portion exposed from the right side of the chassis 200, and the right end portion has a third wall plate 342 with a rear side surface coplanar with the mating surface 340. Alternatively, the support 300 further has a right end portion exposed from the right side of the chassis 200 and a left end portion exposed from the left side of the chassis 200, and the right end portion has a third wall plate 342 with a rear side surface coplanar with the mating surface 340.

[0063] The lower side of the third wall plate 342 is flush with or lower than the lower edge of the mating surface 340, and the upper side of the third wall plate 342 is higher than the bottom surface of the chassis 200. That is, the lower side of the third wall plate 342 is flush with the lower edge of the mating surface 340, and the upper side of the third wall plate 342 is higher than the bottom surface of the chassis 200; or the lower side of the third wall plate 342 is lower than the lower edge of the mating surface 340, and the upper side of the third wall plate 342 is higher than the bottom surface of the chassis 200.

[0064] The third wall plate 342 is used to position and fix the part of the sealing structure corresponding to the left or right mating gap, so as to avoid outdoor air entering the indoor area through the left or right mating gap, thereby further improving the sealing effect.

[0065] Specifically, the third wall plate 342 is two, one third wall plate 342 is exposed from the left side of the chassis 200; and the other third wall plate 342 is exposed from the left side of the chassis 200. The sealing material further includes a second sealing strip 420, and the second sealing strip 420 is two, the first sealing strip 410 is connected between the two second sealing strips 420; one second sealing strip 420 is abutted between one third wall plate 342 and the second limiting surface 125, so as to promote the left mating gap between the chassis 200 and the outer box body 100 to be sealed from the front side; and the other second sealing strip 420 is abutted between the other third wall plate 342 and the third limiting surface 126, so as to promote the right mating gap between the chassis 200 and the outer box body 100 to be sealed from the front side.

[0066] Specifically, the third wall plate 342 is two, and the first wall plate 320 is connected between the two third wall plates 342 in the left-right direction, and the upper end of the third wall plate 342 is located above the lower surface 210 of the chassis 200; a part of one third wall plate 342 corresponds to the left box wall 122, and a part of the other third wall plate 342 corresponds to the right box wall 123.

[0067] The second sealing strips 420 are two, the first sealing strip 410 is connected between the two second sealing strips 420 in the left-right direction, and the upper ends of the second sealing strips 420 are located above the lower surface 210 of the chassis 200; a part of one of the second sealing strips 420 abuts between a part of one of the third wall plates 342 and the left cabinet wall 122; and a part of the other of the second sealing strips 420 abuts between a part of the other of the third wall plates 342 and the right cabinet wall 123. Thus, the left-side matching gap 502 and the right-side matching gap 503 are sealed by the second sealing strips 420, thereby further improving the sealing effect.

[0068] In some optional embodiments, as shown in Figure 7 and Figure 8 The first wall plate 320 includes a first end portion 321 and a second end portion 324 opposite each other in the left-right direction, and the first end portion 321 is located to the left of the second end portion 324. The first end portion 321 and the second end portion 324 are respectively formed with the third wall plate 342.

[0069] A part of the first end portion 321 corresponds to the left cabinet wall 122, so that the left end of the second sealing strip 420 is stopped between the part of the first end portion 321 and the left cabinet wall 122. A part of the first wall plate 320 between the first end portion 321 and the second end portion 324 corresponds to the lower cabinet wall 121, and the part of the first wall plate 320 between the first end portion 321 and the second end portion 324 presses the part of the second sealing strip 420 corresponding thereto on the lower cabinet wall 121. A part of the second end portion 324 corresponds to the right cabinet wall 123, so that the other end of the second sealing strip 420 is stopped between the part of the second end portion 324 and the right cabinet wall 123.

[0070] The left end of the sealing structure is pressed on the left cabinet wall 122 by the first end portion 321, and the right end of the sealing structure is pressed on the right cabinet wall 123 by the second end portion 324, so that the sealing structure can seal the gap between the left cabinet wall 122 and the chassis and the gap between the right cabinet wall 123 and the chassis, and the outdoor air cannot enter the indoor area through the gap between the left cabinet wall 122 and the chassis and the gap between the right cabinet wall 123 and the chassis, thereby further improving the sealing effect.

[0071] In some embodiments, the first sealing strip 410 and the second sealing strip 420 are integrally formed of the same material. Thus, the sealing structure is convenient to install on the support 300, and the installation efficiency is improved.

[0072] In some embodiments, the left end face of one third wall panel 342 is flush with the left end face of one second sealing strip 420; the right end face of another third wall panel 342 is flush with the right end face of another second sealing strip 420. The larger connection area between the support member 300 and the sealing structure makes the connection between the support member 300 and the sealing structure more stable and further improves the sealing effect of the sealing structure.

[0073] In addition, the sealing structure can fill the gap between the first wall panel 320 and the left box wall 122 and the right box wall 123, improving the overall integrity of the through-wall air conditioner in this embodiment.

[0074] In some embodiments, such as Figure 7 and Figure 8 As shown, the intersections of the lower surface 210 of the chassis 200 and its two sides are all rounded at corners 124. That is, the left end of the lower surface 210 of the chassis 200 and the lower end of its left side are smoothly transitioned into a rounded corner 124 via an arc surface, and the right end of the lower surface 210 of the chassis 200 and the lower end of its right side are also smoothly transitioned into a rounded corner 124 via an arc surface. It is understandable that the rounded corners 124 on the exterior surfaces of the chassis 200 not only improve its aesthetics, but also prevent users from being cut during installation or use, as there are no sharp edges on the exterior surfaces.

[0075] The first end portion 321 includes a first segment 322 and a second segment 323. The first segment 322 corresponds to the left sidewall 122, and its upper end is located above the lower surface 210 of the chassis 200. The second segment 323 corresponds to a rounded corner 124 of the chassis 200, and its upper surface is an arc surface adapted to the rounded corner 124. The second end portion 324 includes a third segment 325 and a fourth segment 326. The third segment 325 corresponds to the right sidewall 123, and its upper end is located above the lower surface 210 of the chassis 200. The fourth segment 326 corresponds to another rounded corner 124 of the chassis 200, and its upper surface is an arc surface adapted to the other rounded corner 124.

[0076] In other words, the second segment 323 of the first end 321 has an arc surface that can enclose the left rounded corner 124 of the chassis, and the fourth segment 326 of the second end 324 has an arc surface that can enclose the left rounded corner 124 of the chassis, so that the part of the sealing structure connected to the second segment 323 of the first end 321 and the part connected to the fourth segment 326 of the second end 324 can seal the gap between the two rounded corners 124 of the chassis and the outer casing 100, thereby further improving the sealing effect.

[0077] In some embodiments, such as Figure 9 and Figure 10As shown, the distance between the end of the mounting plate 310 away from the first wall plate 320 and the connection between the mounting plate 310 and the first wall plate 320 is equal to the distance between the connection between the mounting plate 310 and the first wall plate 320 and the upper end of the first section 322. The distance between the end of the mounting plate 310 away from the first wall plate 320 and the connection between the mounting plate 310 and the first wall plate 320 is equal to the distance between the connection between the mounting plate 310 and the first wall plate 320 and the upper end of the third section 325.

[0078] It can be understood that the support can be produced by bending the plate material to form the support part and the mounting plate 310 respectively. In the embodiment, after the mounting plate 310 is flattened to be in the same plane as the first wall plate 320, the upper end of the mounting plate 310 is flush with the upper end of at least one of the first section 322 and the second section 323 of the first wall plate 320, which reduces material waste during processing, thereby improving material utilization and reducing manufacturing costs.

[0079] In some embodiments, the distance between the left end face of one third wall plate 342 and the left end of the left tank wall 122 is 2-7 mm; and / or, the distance between the right end face of another third wall plate 342 and the right end of the left tank wall 122 is 2-7 mm. On the one hand, it ensures that the third wall plate 342 has a large contact area with the outer tank body 100, thereby further improving the sealing effect of the sealing structure; on the other hand, it avoids material waste caused by the excessive size of the support 300 in the left-right direction, thereby reducing manufacturing costs.

Optionally, the distance between the right end face of the third wall plate 342 on the right side and the right end of the left tank wall 122 is 4-5 mm.

[0084] In some embodiments, the support 300 has a size of 5mm-20mm in the up-down direction.

[0085] Optionally, the support 300 has a size of 5mm-20mm in the up-down direction. Optionally, the support 300 has a size of 8mm-17mm in the up-down direction. The support 300 has a size of 12mm-15mm in the up-down direction. On the one hand, the support 300 sufficiently positions and fixes the first sealing strip 410 in the up-down direction, thereby further improving the sealing effect of the first sealing strip 410; on the other hand, the size of the support 300 in the up-down direction is not too large, thereby avoiding waste of materials and reducing manufacturing cost.
