Detailed ways

The vertical air conditioner indoor unit according to the embodiment of the present invention will be introduced below with reference to FIG. 1 to FIG. 12 . FIG. 1 only shows the front structure of the casing 100 , and does not show the rear structure of the casing, the evaporator and the fan inside the casing. The indoor unit of the vertical air conditioner is connected to the outdoor unit of the air conditioner through pipelines, and the vapor compression refrigeration cycle system is used to realize cooling/heating.

As shown in FIG. 1 , the vertical air conditioner indoor unit according to the embodiment of the present invention includes a casing 100 and a sliding cover assembly. An air outlet 101 is defined on the upper front side of the casing 100 . The sliding cover assembly includes an upper sliding cover 210 and a lower sliding cover 220 slidably disposed on the front side of the casing 100 up and down. The sliding cover assembly is configured such that the upper sliding cover 210 and the lower sliding cover 220 can slide up and down to open or cover the air outlet 101 . Specifically: the upper sliding cover 210 and the lower sliding cover 220 can slide upwards to the front of the air outlet 101, and the upper sliding cover 210 is positioned above the lower sliding cover 220 to cover the air outlet 101 (as shown in Figures 5 and 6) . Make the upper sliding cover 210 and the lower sliding cover 220 slide down to the lower front side of the casing 100, and make the upper sliding cover 210 stack against the front side of the sliding cover 220 to open the air outlet 101 (as shown in Figure 11 and Figure 12 ).

In the embodiment of the present invention, the number of air outlets 101 may be one or multiple. Preferably, a plurality of air outlets 101 are arranged vertically on the front side of the casing 100 . For example, as shown in FIG. 1 , three air outlets 101 may be provided, and the upper sliding cover 210 is used to cover the upper two air outlets, and the lower sliding cover 220 is used to cover the lowermost air outlet. Therefore, the length of the upper sliding cover 210 should be longer than that of the sliding cover 220. When both are in the state of opening all the air outlets 101, the upper sliding cover 210 can completely cover the sliding cover 220, so that the appearance of the air conditioner indoor unit is more beautiful.

In the embodiment of the present invention, the upper sliding cover 210 and the lower sliding cover 220 are used to cover the air outlet 101 . When the two sliding covers are in the state of opening the air outlet 101 , the upper sliding cover 210 is stacked against the front side of the sliding cover 220 . Compared with the scheme of only designing one sliding cover to cover all the air outlets 101, the embodiment of the present invention is equivalent to splitting one sliding cover into two, which reduces the length of the sliding cover, reduces the height space it occupies, and is convenient to install on the machine. More air outlets 101 are provided on the front side of the housing 100, which improves the design margin.

In some embodiments, the vertical air conditioner indoor unit is provided with three sliding tracks on the front side of the casing 100 to install two sliding covers. Fig. 1, Fig. 5 to Fig. 12 all illustrate the design position of three slideways. FIG. 4 only shows three slideways to more clearly show the relative positions and orientations of the three slideways.

As shown in the above figures, the front side of the casing 100 has two first slideways 111 . The two first slideways 111 extend linearly along the vertical direction. Two lateral sides of the upper sliding cover 210 extend a plurality of positioning posts 211 respectively slidably disposed in the two first slideways 111 to allow the upper sliding cover 210 to slide up and down on the front side of the casing 100 .

Two second slideways 112 and two third slideways 113 are disposed on the front side of the casing 100 . The shapes of the second slideway 112 and the third slideway 113 are the same, they both extend in a straight line from top to bottom, and then bend backward. The two third slideways 113 are respectively arranged directly below the two second slideways 112 . The four corners of the sliding cover 220 have four positioning posts 222 , 223 , and the four positioning posts are slidably disposed in the two second slideways 112 and the two third slideways 113 respectively. That is, the two positioning columns 222 on the upper side are respectively disposed in the two second slideways 112 , and the two positioning columns 223 on the lower side are respectively located in the two third slideways 113 . The sliding cover 220 is first slid downwards and then retracted backward, so that the upper sliding cover 210 is stacked against the front side of the sliding cover 220 .

In some embodiments, as shown in FIGS. 2 and 3 , at least one upper buckle 215 is provided at the lower end of the upper sliding cover 210 , and at least one lower buckle corresponding to the upper buckle 215 is provided at the upper end of the sliding cover 220 . Deduction 226. The number of upper buckles 215 can be two, and the two upper buckles 215 are respectively arranged on the lateral sides of the bottom end of the upper sliding cover 210, and the number of lower buckles 226 is two, and the two lower buckles 226 are respectively arranged on the lower end of the sliding cover. 220 horizontal both sides of the top. The slide cover assembly is configured to: when the upper slide cover 210 and the slide cover 220 are in the state of opening the air outlet 101 and the upper slide cover 210 is moved upward, the lower buckle 226 is snapped into the upper buckle 215, so that the slide cover 220 and the slide cover 220 The upper sliding cover 210 moves up synchronously to the state of covering the air outlet 101; when the upper sliding cover 210 and the lower sliding cover 220 are in the state of covering the air outlet 101 and the lower sliding cover 220 is moved down, the lower sliding cover 220 is first moved down, and then Retracting backward makes the lower buckle 226 disengage from the upper buckle 215 , thereby allowing the upper sliding cover 210 to continue to move down to be stacked against the front side of the lower sliding cover 220 .

The specific structure of the upper buckle 215 and the lower buckle 226 is shown in FIG. 3 . When the upper sliding cover 210 and the lower sliding cover 220 move back and forth relative to each other, the two are buckled or separated.

In some embodiments, the sliding cover assembly further includes a driving device configured to drive the upper sliding cover 210 and the lower sliding cover 220 to translate up and down. Specifically, the rear sides of the upper slide cover 210 and the slide cover 220 are respectively provided with racks 213, 224 extending up and down, and the driving device includes a gear 400 meshed with the racks 213, 224 and fixed to the casing 100 to drive The motor 500 rotated by the gear 400 is preferably a stepping motor. When the upper sliding cover 210 and the sliding cover 220 are in the state of covering the air outlet 101 , the lower end of the rack 213 of the upper sliding cover 210 is in contact with the upper end of the rack 224 of the sliding cover 220 . In this way, one motor 500 and one gear 400 can be used not only to cooperate with the rack 213 of the upper sliding cover 210, but also to cooperate with the rack 224 of the lower sliding cover 220, without setting two motors up and down.

Preferably, the number of the rack 213 of the upper sliding cover 210 , the rack 224 of the lower sliding cover 220 , the gear 400 and the motor 500 are two respectively. Moreover, the two racks 213 of the upper sliding cover 210 are respectively arranged on two horizontal sides of the rear side of the upper sliding cover 210 , and the two racks 224 of the sliding cover 220 are respectively arranged on two lateral sides of the rear side of the sliding cover 220 . For simplicity, the above figures only show one motor 500 and one gear 400 .

In addition, the sliding cover assembly is further configured: when the upper sliding cover 210 and the lower sliding cover 220 are in the state of opening the air outlet 101 , the gear 400 is located on the top of the rack 213 of the upper sliding cover 210 . In this way, it can push the upper sliding cover 210 to move upward, and then make the upper sliding cover 210 pull the sliding cover 220 to move upward.
