[0057] like Figure 1 and Figure 2 As shown, the air conditioner in this embodiment of the invention can be a split-type wall-mounted air conditioner. Because the chassis of a traditional air conditioner is directly formed as part of the rear volute of the air duct, the placement of the indoor heat exchanger is limited. For example, when using a high-efficiency model with multiple U-tubes as the indoor heat exchanger at the rear of the air conditioner, a deep wall is formed between the rear indoor heat exchanger and the air duct formed by the chassis, making chassis manufacturing difficult. Consequently, only the front of the air conditioner or a low-efficiency indoor heat exchanger can be placed for heat exchange, affecting the performance of the air conditioner and resulting in poor cooling or heating effects.

[0058] To this end, the air conditioner with the structure of the volute tongue part of the air duct and the chassis being separately arranged is designed in the embodiment of the present application, so that the chassis does not limit the arrangement of the indoor heat exchanger, the air conditioner can be provided with the indoor heat exchanger with higher energy efficiency for heat exchange, specifically, the indoor heat exchanger can be provided with the high energy efficiency model with multiple U tubes, the performance of the air conditioner is improved, and the air conditioner has better refrigeration or heating effect.

[0059] Hereinafter, the air conditioner 100 according to the embodiment of the present application will be described with reference to the accompanying drawings. Figures 1-23 The air conditioner 100 according to the embodiment of the present application can include a chassis 1, a rear volute tongue 2, a rotatable fan wheel 5, and an indoor heat exchanger 6.

[0060] The air conditioner 100 according to the embodiment of the present application can include a chassis 1, a rear volute tongue 2, a rotatable fan wheel 5, and an indoor heat exchanger 6.

[0061] The chassis 1 is used to support and install the components of the various parts in the air conditioner 100, and ensure the stable arrangement of the components of the various parts in the air conditioner 100. The chassis 1 includes a horizontal extension 11 and a vertical extension 12, and the horizontal extension 11 and the vertical extension 12 define an installation area for installing the components of the various parts in the air conditioner 100.

[0062] After the air conditioner 100 is installed on the wall, the horizontal extension 11 is located at the lower side of the air conditioner 100 and is connected to the lower end of the vertical extension 12 to support the components of the various parts in the air conditioner 100 at the lower side, and the vertical extension 12 is connected to the rear side of the horizontal extension 11, specifically, the vertical extension 12 is located at the side where the air conditioner 100 is installed in cooperation with the wall to support the components of the various parts in the air conditioner 100 at the rear side of the air conditioner 100, and ensure the stability of the overall arrangement of the air conditioner 100.

[0063] Further, the rear volute tongue 2 can form a part of the air duct of the air conditioner 100, specifically, the rear volute tongue 2 can form the volute tongue part of the air duct, and the rear volute tongue 2 is arranged on the chassis 1 and is separately arranged from the chassis 1. That is, after the rear volute tongue 2 and the chassis 1 are respectively formed, the rear volute tongue 2 is installed on the chassis 1 through the limiting installation structure to form the volute tongue part of the air duct, so as to facilitate the processing of the chassis 1 and the rear volute tongue 2, and ensure the stability of the arrangement of the air duct.

[0064] In addition, since the rear volute tongue 2 and the chassis 1 are separately arranged and respectively formed, the indoor heat exchanger 6 with higher energy efficiency can be arranged in the air conditioner 100 for heat exchange without affecting the processing and manufacturing of the chassis 1, and the indoor heat exchanger 6 can be provided with the high energy efficiency model with multiple U tubes, the performance of the air conditioner 100 is improved, and the air conditioner 100 has better refrigeration or heating effect.

[0065] Further, the first mounting area 3 is defined between the rear volute tongue 2 and the vertical extension 12, and the first mounting area 3 can be used to mount a part of the indoor heat exchanger 6. The second mounting area 4 is defined between the rear volute tongue 2 and the horizontal extension 11, and the second mounting area 4 can be used to mount the fan wheel 5 and another part of the indoor heat exchanger 6.

[0066] Further, the indoor heat exchanger 6 comprises a first heat exchange part 61 arranged in the first mounting area 3, and the indoor heat exchanger 6 further comprises a second heat exchange part 62 arranged in the second mounting area 4, and the second heat exchange part 62 and the first heat exchange part 61 jointly constitute the indoor heat exchanger 6 and jointly complete the heat exchange of the air in the air conditioner 100. The arrangement of the first heat exchange part 61 and the second heat exchange part 62 makes the indoor heat exchanger 6 have a larger heat exchange area, improves the performance of the air conditioner 100, and makes the cooling or heating effect of the air conditioner 100 better.

[0067] The fan wheel 5 can guide the air that has been heat exchanged by the indoor heat exchanger 6 into the air duct when rotating, so that the air whose temperature has been adjusted by the indoor heat exchanger 6 can enter the air duct and be discharged from the air conditioner 100 through the air duct, so as to achieve the purpose of adjusting the indoor air temperature. The fan wheel 5 is arranged in the second mounting area 4, so as to arrange the fan wheel 5 in the air duct, so that the fan wheel 5 can guide the air that has been heat exchanged into the air duct. Moreover, the fan wheel 5 is arranged close to the rear volute tongue 2 and between the first heat exchange part 61 and the second heat exchange part 62, and the rear volute tongue 2 is between the fan wheel 5 and the first heat exchange part 61, so as to make the overall structure of the air conditioner 100 more reasonable and make the temperature adjustment effect of the air conditioner 100 better.

[0068] According to the air conditioner 100 of the embodiment of the present application, the bottom plate 1 and the rear volute tongue 2 are arranged separately, which avoids the limitation of the bottom plate 1 on the arrangement of the indoor heat exchanger 6, and the air conditioner 100 can arrange a larger area of the indoor heat exchanger 6 inside for heat exchange, and the indoor heat exchanger 6 can adopt a higher energy efficiency model, which improves the performance of the air conditioner 100.

[0069] As shown in Figure 3 , the rear volute tongue 2 extends along the length direction of the bottom plate 1 to constitute a complete air duct, and as shown in Figures 2-5 , the rear volute tongue 2 is connected to the bottom plate 1 in a clamping manner, so as to avoid unnecessary fasteners 8, ensure the stability of the connection between the rear volute tongue 2 and the bottom plate 1, and further ensure the stability of the air duct arrangement.

[0070] As shown in Figure 10As shown in the drawings, the rear volute tongue 2 comprises a volute tongue part 21 and a mounting part 22, the volute tongue part 21 faces one side of the wind wheel 5 and constitutes part of the rear volute tongue 2 of the air duct, the mounting part 22 is connected to the side of the volute tongue part 21 away from the wind wheel 5, and the mounting part 22 is used to mount the rear volute tongue 2 on the chassis 1, so that the rear volute tongue 2 can be stably arranged on the chassis 1, and the stability of the air duct arrangement is ensured.

[0071] At least one of the volute tongue part 21 and the mounting part 22 is connected with the chassis 1, so that the rear volute tongue 2 is connected with the chassis 1 as a whole, and the rear volute tongue 2 is arranged more stably.

[0072] As shown in the drawings, Figure 7 , Figure 9 and Figure 12 , the volute tongue part 21 is provided with a plurality of buckles 211 arranged at intervals along the length direction thereof, the chassis 1 is provided with a plurality of clamping holes 13 arranged at intervals along the length direction thereof, and the plurality of buckles 211 are clamped and matched with the plurality of clamping holes 13 one by one, as shown in the drawings, Figure 5 , the buckles 211 and the clamping holes 13 are matched to limit the rear volute tongue 2 in the height direction of the rear volute tongue 2, so as to fixedly connect the rear volute tongue 2 on the chassis 1, and the stability of the arrangement of the rear volute tongue 2 is ensured. Moreover, the rear volute tongue 2 and the chassis 1 are connected through a plurality of clamping holes 13 and buckles 211 arranged at intervals, so as to ensure that the forces at the connection positions of each buckle 211 and clamping hole 13 are balanced, and the stability of the arrangement of the rear volute tongue 2 is further improved.

[0073] As shown in the drawings, Figure 7 and Figure 8 , the two ends of the volute tongue part 21 are respectively provided with first connecting holes 212, and the two ends of the chassis 1 are respectively provided with second connecting holes 14, and the volute tongue part 21 and the chassis 1 are connected through the fasteners 8 penetrating the first connecting holes 212 and the second connecting holes 14. Thus, the fasteners 8 connect the chassis 1 and the rear volute tongue 2 together through the first connecting holes 212 and the second connecting holes 14, and the stability of the connection between the rear volute tongue 2 and the chassis 1 is ensured.

[0074] Specifically, as shown in the drawings, Figure 7 , the two ends of the volute tongue part 21 are provided with connecting parts, the connecting parts protrude away from the mounting part 22, and the connecting parts have recesses recessed inward in the interiors thereof, and the interiors of the recesses are provided with the first connecting holes 212. Thus, the connecting parts can be arranged around the first connecting holes 212 to seal the first connecting holes 212, so as to avoid the air in the air duct from leaking through the first connecting holes 212, and also avoid the condensate water and the like from the outside from entering the air duct through the first connecting holes 212, and the air conditioner 100 has good use performance.

[0075] Moreover, the first connecting holes 212 are arranged in the recesses, so as to avoid the arrangement of the fasteners 8 from occupying more space, and the compactness of the overall structure of the air conditioner 100 is ensured.

[0076] As Figure 6 shown, the length direction of the mounting portion 22 is provided with a limiting rib 221 extending towards the volute tongue portion 21, and the chassis 1 is provided with a partition plate 15 on both sides of the length direction of the volute tongue portion 21 to separate the air outlet and the motor. The limiting rib 221 is stopped outside the corresponding partition plate 15, so that the rear volute tongue 2 can be limited in the length direction of the chassis 1 by the cooperation of the limiting rib 221 and the partition plate 15, and the stability of the rear volute tongue 2 is ensured. Moreover, the volute tongue portion 21 is located between the two partition plates 15 to avoid the influence of the limiting rib 221 on the arrangement of the air duct component.

[0077] Referring Figure 5 to the drawings, the mounting portion 22 and the volute tongue portion 21 define a downwardly open slot 23 therebetween, specifically, the mounting portion 22 extends from top to bottom at the middle position of the volute tongue portion 21, and the volute tongue portion 21 extends from top to bottom away from the mounting portion 22, so that the downwardly open slot 23 is formed between the mounting portion 22 and the volute tongue portion 21. Further, the chassis 1 is formed with a plug plate 121 extending between the air wheel 5 and the first heat exchange portion 61, and the plug plate 121 is inserted into the slot 23 to cooperate with the slot 23. Thus, the rear volute tongue 2 can be limited in the width direction of the rear volute tongue 2, so that the rear volute tongue 2 cannot shake in the width direction, and the stability of the rear volute tongue 2 is ensured.

[0078] As Figures 2-5 shown, the plug plate 121 is inclined towards the second mounting area 4 to avoid the influence of the plug plate 121 and the rear volute tongue 2 on the arrangement of the structure in the first mounting area 3.

[0079] As Figures 2-5 shown, since the slot 23 defined between the mounting portion 22 and the volute tongue portion 21 extends downwardly from front to back when the volute tongue portion 21 forms part of the air duct, the plug plate 121 gradually extends upwardly from back to front, so as to cooperate with the extension direction of the slot 23 defined between the mounting portion 22 and the volute tongue portion 21, and the cooperation between the plug plate 121 and the slot 23 is more closely, and the stability of the rear volute tongue 2 is ensured.

[0080] In summary, by the snap-fit of the plurality of buckles 211 arranged along the length direction of the rear volute tongue 2 on the volute tongue part 21 and the plurality of clamping holes 13 arranged along the length direction of the chassis 1, and by the fastening of the fastener 8 through the first connecting holes 212 arranged at both ends of the volute tongue part 21 and the second connecting holes 14 arranged at both ends of the chassis 1, and by the limiting of the limiting ribs 221 at both ends of the mounting part 22 and the partition plates 15 arranged at both ends of the chassis 1, and by the insertion of the insertion slot 23 defined between the mounting part 22 and the volute tongue part 21 and the insertion plate 121 arranged on the chassis 1, the rear volute tongue 2 can be stably connected to the chassis 1, and the stability of the rear volute tongue 2 is ensured.

[0081] Specifically, the assembly process of the rear volute tongue 2 can be that, first, the insertion slot 23 of the rear volute tongue 2 is inserted into the insertion plate 121 arranged on the chassis 1, at this time, the rear volute tongue 2 is limited in the width direction of the rear volute tongue 2, and then the rear volute tongue 2 is further moved in the insertion direction until the plurality of buckles 211 arranged along the length direction of the rear volute tongue 2 are inserted into the plurality of clamping holes 13 arranged along the length direction of the chassis 1 one by one, at this time, the limiting ribs 221 at both ends of the mounting part 22 abut against the partition plates 15 arranged at both ends of the chassis 1 to limit the rear volute tongue 2 in the length direction of the rear volute tongue 2, and then the rear volute tongue 2 is further moved away from the mounting part 22 to make the buckles 211 abut against one side edge of the clamping holes 13 to limit the rear volute tongue 2 in the height direction of the rear volute tongue 2, at this time, the first connecting holes 212 arranged at both ends of the volute tongue part 21 and the second connecting holes 14 arranged at both ends of the chassis 1 are one by one corresponding, the fastener 8 is inserted into the first connecting holes 212 and the second connecting holes 14, and the rear volute tongue 2 is stably fixed on the chassis 1 as a whole through the first connecting holes 212 and the second connecting holes 14.

[0082] In the use process of the air conditioner, a large amount of condensate water is generated at the indoor heat exchanger 6, in order to avoid the condensate water from corroding the wall where the air conditioner 100 is installed and affecting other components in the air conditioner 100 and affecting the service life of the air conditioner 100, therefore, a water receiving structure is further arranged on the chassis 1 to receive the condensate water generated at the indoor heat exchanger 6 and the wall surface nearby and guide the condensate water out of the air conditioner 100, so as to avoid the condensate water from affecting the normal operation of the air conditioner 100.

[0083] As shown in Figure 2 and Figure 11 , the chassis 1 has a first water receiving part 16 and a water outlet 17, the first water receiving part 16 is arranged below the first heat exchange part 61 to receive the first condensate water generated by the first heat exchange part 61 and guide the first condensate water to the water outlet 17.

[0084] Specifically, the first condensed water generated at the first heat exchange portion 61 falls onto the first water receiving portion 16 under the action of gravity, and the first water receiving portion 16 is adapted to guide the first condensed water to the water outlet 17, which guides the first condensed water received by the first water receiving portion 16 to a preset position, for example, a water pan or outside the air conditioner 100, so that the first condensed water generated at the first heat exchange portion 61 is treated, the erosion of other components in the air conditioner 100 by the first condensed water is avoided, and the service life of the air conditioner 100 is improved.

[0085] With reference to Figure 2 and Figure 11 , the chassis 1 further has a second water receiving portion 18 arranged below the second heat exchange portion 62 to receive the second condensed water generated at the second heat exchange portion 62 and guide the second condensed water towards the water outlet 17.

[0086] Specifically, the second condensed water generated at the second heat exchange portion 62 falls onto the second water receiving portion 18 under the action of gravity, and the second water receiving portion 18 is adapted to guide the second condensed water to the water outlet 17, which guides the second condensed water received by the second water receiving portion 18 to a preset position, for example, a water pan or outside the air conditioner 100, so that the second condensed water generated at the second heat exchange portion 62 is treated, the erosion of other components in the air conditioner 100 by the second condensed water is avoided, and the service life of the air conditioner 100 is improved.

[0087] Further, the portions of the first water receiving portion 16 and the second water receiving portion 18 close to the water outlet 17 gradually extend downward along the direction close to the water outlet 17 to guide the condensed water to the water outlet 17 by the action of gravity, avoid the retention of condensed water in the air conditioner 100 to erode other components in the air conditioner 100, and improve the service life of the air conditioner 100.

[0089] Further, on the same horizontal plane, the first water outlet 171 and the second water outlet 172 are both located between the first water receiving portion 16 and the second water receiving portion 18, so that the first water outlet 171 and the second water outlet 172 can simultaneously guide the condensed water received by the first water receiving portion 16 and the second water receiving portion 18 out of the air conditioner 100, avoiding the need to provide multiple water outlets 17 at the first water receiving portion 16 and the second water receiving portion 18, thus simplifying the structure and facilitating processing and manufacturing.

[0090] After the rear volute tongue 2 is assembled to the chassis 1, a cavity 7 is formed between the rear volute tongue 2, the plug plate 121 and the chassis 1. When the air conditioner 100 is cooling, the temperature inside the cavity 7 is higher than the temperature around the cavity 7, which causes condensed water to form on the inner wall of the cavity 7. In order to prevent this part of the condensed water from flowing out of the air duct opening and eroding the wall on which the air conditioner 100 is installed, a first drain hole 711 is further provided on the bottom wall 71 of the cavity 7, and the bottom wall 71 is part of the chassis 1.

[0091] Specifically, the cavity 7 is defined between the rear volute tongue 2, the plug plate 121 and the chassis 1, and more specifically, the cavity 7 is defined between the plug plate 121 and a portion of the chassis 1 on the lower side of the volute tongue portion 21 at the connection between the volute tongue portion 21 and the mounting portion 22. The bottom wall 71 of the cavity 7 is provided with the first drain hole 711, and the bottom wall 71 of the cavity 7 receives the condensed water generated in the cavity 7 and guides the condensed water towards the first drain hole 711.

The first drain hole 711 guides the condensed water received by the bottom wall 71 of the cavity 7 to a predetermined position. Thus, the condensed water generated in the cavity 7 is treated, and the wall is prevented from being eroded by the condensed water, thereby improving the performance of the air conditioner 100.

[0093] Specifically, the condensed water generated in the cavity 7 falls onto the bottom wall 71 of the cavity 7 under the action of gravity, and the bottom wall 71 of the cavity 7 is adapted to guide the condensed water to the first drain hole 711. The first drain hole 711 guides the condensed water received by the bottom wall 71 of the cavity 7 to a predetermined position. Thus, the condensed water generated in the cavity 7 is treated, and the wall is prevented from being eroded by the condensed water, thereby improving the performance of the air conditioner 100.

[0094] Specifically, the third condensate water generated in the cavity 7 falls on the bottom wall 71 of the cavity 7 under the action of gravity, the bottom wall 71 of the cavity 7 is adapted to guide the third condensate water to the first drain hole 711, the first drain hole 711 guides the third condensate water received by the bottom wall 71 of the cavity 7 to the third water receiving portion 19, the third water receiving portion 19 is adapted to guide the third condensate water to the water outlet 17, the water outlet 17 guides the third condensate water received by the third water receiving portion 19 to a predetermined position, for example, a water receiving tray or outside the air conditioner 100, thereby the third condensate water generated in the cavity 7 is treated, the third condensate water is prevented from eroding the wall, and the use performance of the air conditioner 100 is improved.

[0095] Further, the first drain hole 711 is located at both ends of the length direction of the bottom wall 71 to improve the drainage speed.

[0097] In combination with the embodiments shown in Figure 12 and Figure 15 , the cavity 7 also has a plurality of clamping holes 13 arranged at intervals along the length direction of the bottom plate 1, the plurality of buckles 211 arranged at intervals along the length direction of the volute tongue portion 21 are matched with the clamping holes 13, therefore the condensate water generated in the cavity 7 can also flow out from the matching gap between the buckles 211 and the clamping holes 13, and can be discharged together with the condensate water discharged from the first drain hole 711, thereby under the joint action of the clamping holes 13 and the first drain hole 711, the condensate water is prevented from remaining in the cavity 7, the remaining condensate water is prevented from eroding other components in the air conditioner 100 or the wall where the air conditioner 100 is installed, and the service life and use performance of the air conditioner 100 are improved.

The limiting rib 221 is stopped outside the corresponding partition plate 15. Since the volute tongue portion 21 is located between the two partition plates 15, the limiting rib 221 cooperates with the partition plate 15 and can also block the condensed water in the cavity 7 from entering the air duct through the joint of the mounting portion 22 and the bottom plate 1, thereby avoiding the condensed water flowing out of the air conditioner through the air duct and corroding the wall, and further improving the use performance of the air conditioner 100.
