[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0046] Combination Figures 1 to 11 As shown, the embodiment of the present disclosure provides an indoor unit and an air conditioner. The indoor unit includes a chassis 10, an evaporator 20 and a fixing bracket 30.

[0047] like Figure 1 , Figure 2 and Figure 5 As shown, the fixing bracket 30 includes a first connecting portion 301 and a second connecting portion 302 connected to each other. The first connecting portion 301 is suitable for connecting to the bottom plate 10 , and the evaporator 20 is disposed at the second connecting portion 302 .

[0048] Among them, one of the chassis 10 and the first connecting part 301 is provided with a first mounting structure 40, and the other of the chassis 10 and the first connecting part 301 is provided with a second mounting structure 41 and a third mounting structure 42. The second mounting structure 41 and the third mounting structure 42 are selectively matched with the first mounting structure 40 to connect the first connecting part 301 with the chassis 10.

[0049] The first connection part 301 is fixedly connected to the chassis 10, one of the chassis 10 and the first connection part 301 is provided with a first mounting structure 40, and the other of the chassis 10 and the first connection part 301 is provided with a second mounting structure 41 and a third mounting structure 42. Fig. 9 and Fig.11 As shown, the chassis is provided with a first mounting structure, and the first connecting portion is provided with a second mounting structure 41 and a third mounting structure 42. The second mounting structure 41 can be matched with the first mounting structure 40, and the third mounting structure 42 can also be matched with the first mounting structure 40. In actual use, one of the second mounting structure 41 and the third mounting structure 42 is matched with the first mounting structure 40.

[0050] Taking the example that the first mounting structure 40 is provided on the chassis 10 and the second mounting structure 41 and the third mounting structure 42 are provided on the first connecting portion 301, when the position of the fixing bracket 30 relative to the chassis 10 changes, the positions of the second mounting structure 41 and the third mounting structure 42 relative to the first mounting structure 40 change, so that one of the second mounting structure 41 and the third mounting structure 42 corresponding to the first mounting structure 40 can be selected to cooperate with the first mounting structure 40, so that the fixing bracket 30 can be quickly and efficiently fixed on the chassis 10 when the position of the fixing bracket 30 relative to the chassis 10 changes.

[0051] Alternatively, if Figure 3 , Figure 7 , Fig. 9 and Fig.11 As shown, the first mounting structure 40 includes a positioning portion 401 and a limiting portion 43 , and the second mounting structure 41 and the third mounting structure 42 both include a positioning matching portion 411 and a limiting matching portion 432 .

[0052] The limiting portion 43 cooperates with the limiting matching portion 432 to pre-position the first connecting portion 301 and the chassis 10 , and the positioning portion 401 cooperates with the positioning matching portion 411 to fix the relative position between the first connecting portion 301 and the chassis 10 .

[0053] Combination Fig. 9As shown, taking the cooperation between the second mounting structure 41 and the first mounting structure 40 as an example, the relative position between the first connection part 301 and the chassis 10 can be pre-fixed by cooperating with the limiting matching part 43 and the limiting matching part 432 of the second mounting structure 41, and the position of the fixed bracket 30 on the chassis 10 can be limited. Then, the positioning part 401 is matched with the positioning matching part 411 of the second mounting structure 41 to fix the first connection part 301 and the chassis 10, thereby improving the stability of the connection between the first connection part 301 and the chassis 10 and facilitating installation.

[0054] Alternatively, if Figure 3 , Figure 7 , Fig. 9 and Fig.11 As shown, the positioning portion 401 includes a first positioning hole 4011 , the positioning matching portion 411 includes a second positioning hole 4111 matched with the first positioning hole 4011 , and the first positioning hole 4011 is screw-connected to the second positioning hole 4111 .

[0055] One of the limiting portion 43 and the limiting matching portion 432 includes a limiting hole 4321 , and the other of the limiting portion 43 and the limiting matching portion 432 includes a limiting protrusion 431 , which is matched with the limiting hole 4321 and inserted into the limiting hole 4321 .

[0056] Combination Fig. 9 and Fig.11 As shown, the cooperation between the limiting hole 4321 and the limiting protrusion 431 plays a role in pre-positioning the fixing bracket 30, and the first positioning hole 4011 and the second positioning hole 4111 are connected by screws to fix the fixing bracket 30 on the chassis 10.

[0057] The screw passes through the first positioning hole 4011 and the second positioning hole 4111 to achieve a fixed connection between the first connecting portion 301 and the chassis 10 .

[0058] The limiting portion 43 includes a limiting hole 4321, and the limiting matching portion 432 includes a limiting protrusion 431, or the limiting portion 43 includes a limiting protrusion 431, and the limiting matching portion 432 includes a limiting hole 4321. The limiting protrusion 431 is inserted into the limiting hole 4321 to achieve pre-positioning between the fixing bracket 30 and the chassis 10.

[0059] By connecting the first positioning hole 4011 and the second positioning hole 4111 and adapting the limiting hole 4321 and the limiting protrusion 431, the relative position of the fixing bracket 30 and the chassis 10 can be limited, so that the fixing bracket 30 can be fixed on the chassis 10, and then the evaporator 20 can be fixed.

[0060] The matching of the limiting protrusion 431 and the limiting hole 4321 means that the limiting protrusion 431 and the limiting hole 4321 have the same shape and are equal or nearly equal in size. For example, if the limiting hole 4321 is circular, the cross section of the limiting protrusion 431 is also circular, and the sizes of the two circles are equal or nearly equal.

[0061] Alternatively, if Figure 3 and Figure 7 As shown, the first positioning hole 4011 and the limiting hole 4321 have different shapes, so the first positioning hole 4011 and the limiting protrusion 431 also have different shapes. For example, one of the first positioning hole 4011 and the limiting hole 4321 is elliptical, and the other of the first positioning hole 4011 and the limiting hole 4321 is circular.

[0062] The first positioning hole 4011 and the limiting hole 4321 have different sizes, so the first positioning hole 4011 and the limiting protrusion 431 also have different sizes. For example, the opening size of the first positioning hole 4011 is larger or smaller than the opening size of the limiting hole 4321.

[0063] The first positioning hole 4011 and the limiting hole 4321 have different shapes and / or sizes. Therefore, when the fixing bracket 30 is assembled on the chassis 10, it can prevent the first positioning hole 4011 from being matched with the limiting protrusion 431 and the limiting hole 4321 from being screwed with the second positioning hole 4111, thereby preventing the operator from confusing the first positioning hole 4011 with the limiting hole 4321 during the installation process, thereby improving the accuracy of the installation. On the other hand, it can also visually distinguish the first positioning hole 4011 and the limiting hole 4321 quickly, thereby improving the assembly efficiency.

[0064] It can be understood that the positioning portion 401 may not be in the form of the first positioning hole 4011. For example, one of the positioning portion 401 and the positioning matching portion 411 is a first clip, and the other is a first slot. The first clip is adapted to the first slot, and the first clip is inserted into the first slot to achieve the snap connection between the positioning portion 401 and the positioning matching portion 411.

[0065] The limiting portion 43 may also not be in the form of the limiting hole 4321 or the limiting protrusion 431. For example, one of the limiting portion 43 and the limiting matching portion 432 is a second buckle, and the other is a second slot. The second buckle is adapted to the second slot, and the second buckle is inserted into the second slot to achieve the snap connection between the limiting portion 43 and the limiting matching portion 432.

[0066] Optionally, the second mounting structure 41 and the third mounting structure 42 are sequentially arranged along the width direction of the evaporator 20 .

[0067] The second mounting structure 41 and the third mounting structure 42 are located in a plane and are sequentially arranged along the width direction of the evaporator 20 , so that when evaporators 20 of different widths are installed, the position of the movable fixing bracket 30 is adjusted along the width direction of the evaporator 20 .

[0068] like Figures 1 to 7 As shown, when the first connection portion 301 includes the second mounting structure 41 and the third mounting structure 42, the second mounting structure 41 and the third mounting structure 42 move along the width direction of the evaporator 20 with the fixing bracket 30, and after the second connection portion 302 is in place with the evaporator 20, as shown in FIG. Fig. 9 As shown, if the second mounting structure 41 corresponds to the first mounting structure 40 at this time, the limiting matching portion 432 of the second mounting structure 41 is matched with the limiting portion 43, and the positioning matching portion 411 of the second mounting structure 41 is matched with the positioning portion 401; as shown in FIG. Fig.11 As shown, if the third mounting structure 42 corresponds to the first mounting structure 40 at this time, the limiting matching portion 432 of the third mounting structure 42 is matched with the limiting portion 43, and the positioning matching portion 411 of the third mounting structure 42 is matched with the positioning portion 401 to achieve fixation between the first connecting portion 301 and the chassis 10.

[0069] When the first connection part 301 includes the first mounting structure 40, the first mounting structure 40 moves along the width direction of the evaporator 20 with the fixing bracket 30. After the second connection part 302 is matched with the evaporator 20, if the first mounting structure 40 corresponds to the second mounting structure 41 at this time, the limiting matching part 432 of the second mounting structure 41 is matched with the limiting part 43, and the positioning matching part 411 of the second mounting structure 41 is matched with the positioning part 401. If the first mounting structure 40 corresponds to the third mounting structure 42 at this time, the limiting matching part 432 of the third mounting structure 42 is matched with the limiting part 43, and the positioning matching part 411 of the third mounting structure 42 is matched with the positioning part 401, so as to realize the fixation between the first connection part 301 and the chassis 10.

[0070] In this way, the fixing brackets 30 adapted to the evaporators 20 of different widths can all be fixed on the chassis 10 .

[0071] By cooperating with the first mounting structure 40 and the second mounting structure 41 or with the third mounting structure 42, it can be achieved that the fixed bracket 30 can still be fixedly connected to the chassis 10 when it is moved to different positions along the width direction of the evaporator 20, so that the fixed bracket 30 can be used to fix evaporators 20 of different widths, thereby eliminating the need to set up multiple fixed brackets 30, saving costs, and achieving compatibility with evaporators 20 of multiple different widths.

[0072] Optionally, the second connection portion 302 can be switched between a first state and a second state.

[0073] In the first state, the second connection part 302 cooperates with the N rows of evaporators 20 to limit the N rows of evaporators 20; in the second state, the second connection part 302 cooperates with the M rows of evaporators 20 to limit the M rows of evaporators 20, N and M are positive integers and N≠M.

[0074] like Figure 3 and Fig. 9 As shown, N=3, the second connection portion 302 is in the first state; Figure 7 and Fig.11 As shown, M=2, and the second connecting portion 302 is in the second state.

[0075] In the first state, the second connecting portion 302 is suitable for cooperating with N rows of evaporators 20 and can limit the N rows of evaporators 20. In the second state, the second connecting portion 302 is suitable for cooperating with M rows of evaporators 20 and can limit the M rows of evaporators 20. N and M are not equal, so that the second connecting portion 302 can cooperate and limit the evaporators 20 of different sizes, so that the fixed bracket 30 can be compatible with a variety of evaporators 20.

[0076] N can be 1, 2, 3, etc. M can be 1, 2, 3, etc. N and M are unequal positive integers, and the fixing bracket 30 can fix a single row or multiple rows of evaporators 20 .

[0077] By switching the second connection part 302 between the first state and the second state, the second connection part 302 can limit the positions of evaporators 20 of different numbers, so that the same fixing bracket 30 can be adapted to evaporators 20 of different widths, thereby improving the versatility of the fixing bracket 30. The fixing bracket 30 provided in the embodiment of the present disclosure can reduce the number of fixing brackets 30, thereby saving the mold cost required for molding the fixing bracket 30 and reducing the cost investment. At the same time, it can also avoid the management confusion caused by too many molds.

[0078] Optionally, the second connection portion 302 includes a first connection plate 3021 and a second connection plate 3022 .

[0079] One end of the first connecting plate 3021 is connected to the first connecting portion 301 .

[0080] The second connecting plate 3022 is connected to the other end of the first connecting plate 3021 and a first bend 304 is formed at the connection. The first connecting plate 3021 and the second connecting plate 3022 together enclose an installation space 311 for installing the evaporator 20. The first bend 304 is greater than 0° and less than or equal to 90°. Figure 1 As shown, the first bend 304 is equal to 90°.

[0081] The size of the installation space 311 is different between the first state and the second state.

[0082] In the first state, the size of the installation space 311 is adapted to the width of the N rows of evaporators 20, and in the second state, the size of the installation space 311 is adapted to the width of the M rows of evaporators 20. Thus, by adjusting the size of the installation space 311, the second connection portion 302 can be adapted to evaporators 20 of different rows.

[0083] Optionally, the first connecting plate 3021 is disposed along the width direction of the evaporator 20 (i.e. Figure 8 and Fig. 9 The dimension of the mounting space 311 can be changed in the vertical direction.

[0084] The size of the first connecting plate 3021 along the width direction of the evaporator 20 can be enlarged or reduced, so that the size of the installation space 311 along the width direction of the evaporator 20 can be correspondingly enlarged or reduced, and then the installation space 311 can adapt to evaporators 20 of different rows, thereby improving the versatility of the fixing bracket 30.

[0085] The size of the first connecting plate 3021 along the width direction of the evaporator 20 is variable, so that the position of the first bend 304 along the width direction of the evaporator 20 will change accordingly, and the size of the second connecting plate 3022 will also change accordingly.

[0086] As shown in,9, N=3, as Fig.11 As shown, M=2. From the first state to the second state, the size of the installation space 311 along the width direction of the evaporator 20 needs to be reduced, the size of the first connecting plate 3021 along the width direction of the evaporator 20 is reduced by X, the end of the first connecting plate 3021 connected to the second connecting portion 302 is shortened by X, the first bend 304 moves X along the width direction of the evaporator 20 toward the first connecting portion 301, and the length of the second connecting plate 3022 (as shown in FIG. Figure 5 Increase X in the up and down directions.

[0087] It can be understood that when the total material size of the fixing bracket 30 remains unchanged, by adjusting the size of the first connecting plate 3021 along the width direction of the evaporator 20, the size of the first connecting plate 3021 and the second connecting plate 3022 is changed, thereby changing the size of the installation space 311 along the width direction of the evaporator 20 to fix evaporators 20 of different widths.

[0088] like Figure 1 As shown, the second connection portion 302 further includes a guide section 3023 , and the guide section 3023 is disposed at one end of the second connection plate 3022 away from the first connection plate 3021 .

[0089] Along the direction of inserting the evaporator 20 into the installation space 311 (such as Figure 1The guide section 3023 is inclined toward the direction close to the installation space 311. In this way, the guide section 3023 can provide a clear insertion direction for the evaporator 20 to be inserted into the installation space 311, and guide the evaporator 20 to be smoothly inserted into the installation space 311. The guiding effect of the guide section 3023 can make the insertion process of the evaporator 20 smoother, thereby reducing the difficulty of installation and improving the efficiency of installation.

[0090] like Figure 1 As shown, the fixing bracket 30 also includes a third connecting portion 303, which is connected between the first connecting portion 301 and the second connecting portion 302, and a second bend 305 is formed at the connection between the third connecting portion 303 and the first connecting portion 301, and a third bend 306 is formed at the connection between the third connecting portion 303 and the second connecting portion 302.

[0091] The third connection part 303 is connected between the first connection part 301 and the second connection part 302, which can increase the connection strength between the first connection part 301 and the second connection part 302 and improve the connection stability. The connection between the third connection part 303 and the first connection part 301 forms a second bend 305, and the connection between the third connection part 303 and the second connection part 302 forms a third bend 306, which can improve the structural strength of the connection between the third connection part 303 and the first connection part 301 of the fixing plate and the connection between the third connection part 303 and the second connection part 302, making the fixing bracket 30 more stable, thereby improving the stability of the fixing bracket 30 to fix the evaporator 20.

[0092] like Figure 1 As shown, the third connection portion 303 is connected between the first connection portion 301 and the second connection portion 302, and the third connection portion 303 and the second connection plate 3022 jointly limit the movement of the evaporator 20 in the left and right directions (along the width direction of the evaporator 20). And the first connection plate 3021 can limit the upward movement of the evaporator 20, thereby achieving stable positioning of the evaporator 20.

[0093] Optionally, the fixing bracket 30 is formed by a continuous mold and a quick insert replacement process.

[0094] Combination Figure 1 As shown, the fixing bracket 30 in the first state is formed by a continuous die stamping process, and multiple stamping processes are integrated in a die, which can improve the production efficiency of the fixing bracket 30 and also improve the stability and reliability of the quality of the fixing bracket 30.

[0095] The second state of the fixed bracket 30 can be formed by adding an insert in the mold on the basis of the first state of the fixed bracket 30. The second state of the fixed bracket 30 can also be formed directly by placing an insert in the mold and using a continuous die stamping process. The insert accessories used to form the second connecting portion 302 can be quickly replaced by the rapid insert replacement process, so that the second fixed bracket 30 in the manufactured fixed bracket 30 is located at the second position, which can improve the production efficiency of the fixed bracket 30.

[0096] It is understandable that the fixing bracket 30 in the second state may be formed by a stamping process using a continuous die, and the fixing bracket 30 may be switched from the second state to the first state by quickly changing the insert.

[0097] The disclosed embodiment also provides an air conditioner, comprising an indoor unit and an outdoor unit as described in any one of the above embodiments.
