[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] Please refer to the following Figures 1 to 7 The bottom frame assembly and the air conditioner according to the embodiment of the present utility model are described.

[0034] like Figures 1 to 4 As shown, the base frame assembly of the present embodiment includes: a base frame 2 and a motor cover 1. The motor cover 1 and base frame 2 enclose a motor cavity 3 for mounting the through-flow motor. The motor cavity 3 has an opening 31 and a closed portion 32 arranged axially opposite each other. The motor cover 1 has a first baffle 11, and the base frame 2 has a second baffle 21. The first baffle 11 and the second baffle 21 abut to form the closed portion 32.

[0035] According to the bottom frame assembly of the embodiment of the present invention, the motor cover 1 and the bottom frame 2 enclose a motor cavity 3, and the motor cavity 3 has an opening portion 31 and a closed portion 32 arranged opposite each other along its axial direction, so that external airflow can be stopped by the closed portion 32 to prevent external airflow from entering the air duct. Since the first baffle 11 and the second baffle 21 abut to form the closed portion 32, the crossflow fan can be sealed only by the motor cover 1 and the bottom frame 2 without the need for additional parts. Therefore, the bottom frame assembly of the embodiment of the present invention requires fewer parts to seal the crossflow motor, which is conducive to simplifying the assembly process and reducing production costs.

[0036] It is understood that the first baffle 11 and the second baffle 21 abut against each other to form a motor end cap for sealing the through-flow motor. Thus, the base frame assembly of the present invention can omit the "motor end cap," reducing the number of parts required for base frame assembly and simplifying the base frame assembly process, saving material and labor costs.

[0037] It should be noted that if Figure 4 As shown, opening portion 31 is one end of the opening of motor cavity 3. The output shaft of the through-flow motor extends from opening portion 31 to connect with the through-flow blades. Enclosed portion 32 is the inner end wall of motor cavity 3 (the enclosed end of motor cavity 3). First baffle 11 and second baffle 21 enclose the inner end wall of motor cavity 3 to prevent airflow from entering the air duct through enclosed portion 32, thereby avoiding condensation inside the air duct.

[0038] Alternatively, as Figure 1 、 Figure 2 and Figure 5As shown, the abutting position of the first baffle 11 and the second baffle 21 has a joint seam 6, and one of the first baffle 11 and the second baffle 21 is provided with a shielding rib 111, which extends along the length direction of the joint seam 6 and covers the joint seam 6. It is understandable that the joint seam 6 between the first baffle 11 and the second baffle 21 may cause air leakage. By providing the shielding rib 111, the bottom frame assembly of the embodiment of the present utility model can cover the joint seam 6, thereby reducing the probability of airflow entering the motor cavity 3 and the air duct from the joint seam 6, thereby further improving the sealing effect of the bottom frame assembly.

[0039] In one example, if Figures 4 to 7 The shielding rib 111 is provided on the first baffle 11. In other examples, the shielding rib 111 may also be provided on the second baffle 21, which is not limited in the present invention.

[0040] In other embodiments, one of the first baffle 11 and the second baffle 21 is provided with a convex stopper (not shown), and the other of the first baffle 11 and the second baffle 21 is provided with a concave stopper (not shown), with the convex stopper aligned with the concave stopper. This can increase the contact area between the first baffle 11 and the second baffle 21, further reducing the probability of airflow entering the motor cavity 3 and the air duct through the joint 6.

[0041] For example, a concave stopper is provided on the first baffle 11, and a convex stopper is provided on the second baffle 21. For another example, a convex stopper is provided on the first baffle 11, and a concave stopper is provided on the second baffle 21.

[0042] In some embodiments, as Figure 1 As shown, within a projection plane perpendicular to the axial direction of the motor cavity 3, the outer periphery of the enclosing portion 32 is circular, while the outer peripheries of the first baffle 11 and the second baffle 21 are both semicircular. It is understood that the first baffle 11 is a semicircular plate-like structure, and the second baffle 21 is a semicircular plate-like structure. When the first baffle 11 and the second baffle 21 are spliced ​​together, a circular enclosing portion 32 is formed to accommodate the cylindrical outer structure of the through-flow motor, making the through-flow motor and the base frame assembly more compact and occupying less space.

[0043] Optionally, at least one of the first baffle 11 and the second baffle 21 is provided with a first reinforcing rib 41. This can strengthen the structure of the first baffle 11 / the second baffle 21, thereby improving the structural strength of the first baffle 11 / the second baffle 21 and extending the service life of the bottom frame assembly.

[0044] For example, Figures 4 to 7As shown, a plurality of first reinforcing ribs 41 are provided on the first baffle 11 . The plurality of first reinforcing ribs 41 are provided on one side of the thickness direction of the first baffle 11 , and the plurality of first reinforcing ribs 41 are arranged at intervals along the extension direction of the splicing seam 6 .

[0045] For example, Figure 3 and Figure 4 As shown, a plurality of first reinforcing ribs 41 are provided on the second baffle 21 . The plurality of first reinforcing ribs 41 are provided on one side of the second baffle 21 in the thickness direction, and the plurality of first reinforcing ribs 41 are arranged at intervals along the extension direction of the splicing seam 6 .

[0046] Alternatively, as Figure 3 and Figure 4 As shown, a hollow interlayer 211 is provided in the second baffle 21, and a second reinforcing rib 42 is provided in the hollow interlayer 211. The bottom frame assembly of the embodiment of the present invention can further improve the structural strength of the second baffle 21 by configuring the second baffle 21 with the above structure.

[0047] In some embodiments, as Figure 1 and Figure 6 As shown, one of the first baffle 11 and the second baffle 21 is provided with a lead-in opening 112 extending therethrough, which communicates with the motor cavity 3. The lead-in opening 112 is used to pass the motor wires of the through-flow motor. Since one of the first baffle 11 and the second baffle 21 is provided with a lead-in opening 112 extending therethrough, the motor wires can be led out through the closed portion 32 so as to be electrically connected to the electronic control module on the bottom frame 2, making wiring of the bottom frame assembly more convenient.

[0048] For example, the lead-in port 112 is provided on the first baffle 11 .

[0049] Alternatively, as Figure 2 and Figure 3 As shown, the bottom frame assembly further includes a sealing gasket 5, which is disposed within the motor cavity 3. At least a portion of the sealing gasket 5 is in contact with the sealing portion 32. The sealing gasket 5 is provided with a communication hole 51, through which the lead-in port 112 communicates with the motor cavity 3. It will be appreciated that the sealing gasket 5 is in contact with the inner side of the sealing portion 32 to block the joint 6, thereby preventing airflow from entering the motor cavity 3 through the joint 6 between the first baffle 11 and the second baffle 21, thereby improving the sealing reliability of the through-flow motor.

[0050] For example, the sealing gasket 5 is an elastic rubber gasket, one surface of the sealing gasket 5 contacts the sealing portion 32 , and the other surface of the sealing gasket 5 contacts the through-flow motor.

[0051] In some embodiments, as Figure 4 and Figure 5As shown, one of the motor cover 1 and the base frame 2 is provided with a positioning post 12, and the other of the motor cover 1 and the base frame 2 is provided with a positioning hole 212, and the positioning post 12 is plugged into and fitted with the positioning hole 212. It is understood that when the operator is installing the motor cover 1 on the base frame 2, the positioning post 12 can be aligned with the positioning hole 212 to position the motor cover 1 for installation, thereby facilitating subsequent fixing of the motor cover 1.

[0052] For example, the positioning post 12 is provided on the motor cover 1 , and the positioning hole 212 is provided on the bottom frame 2 .

[0053] like Figures 5 to 7 As shown, there may be two or more positioning posts 12 , and the number of positioning holes 212 is equal to the number of positioning posts 12 and they are connected in a one-to-one correspondence.

[0054] Specifically, if Figure 4 and Figure 5 As shown, the motor cover 1 has a mounting plate 15, the mounting surface of which is perpendicular to the plane of the first baffle 11. Two positioning posts 12 are arranged on the mounting plate 15 at intervals. Two positioning holes 212 are provided on the side of the second baffle 21 facing away from the motor cavity 3, and the two positioning holes 212 correspond one-to-one with the two positioning posts 12.

[0055] In some embodiments, as Figures 5 to 7 As shown, one of the motor cover 1 and the bottom frame 2 is provided with a hook 13, and the other of the motor cover 1 and the bottom frame 2 is provided with a slot (not shown), and the hook 13 engages with the slot. The bottom frame assembly of the embodiment of the present invention is secured to the motor cover 1 and the bottom frame 2 by engaging the hook 13 with the slot, thereby reducing the number of fasteners used and simplifying assembly and disassembly.

[0056] For example, the hook 13 is provided on the motor cover 1 , and the slot is provided on the bottom frame 2 .

[0057] Alternatively, as Figure 3 and Figure 5 As shown, the bottom frame assembly further includes a threaded member (not shown). A first mounting position 14 is provided on one of the motor cover 1 and the bottom frame 2, and a second mounting position 22 is provided on the other of the motor cover 1 and the bottom frame 2. The threaded member is passed through the first mounting position 14 and the second mounting position 22. The first mounting position 14 can be a threaded column (with a threaded hole inside) or a threaded hole, and the second mounting position 22 can be a threaded column (with a threaded hole inside) or a threaded hole. The bottom frame assembly of the embodiment of the utility model can improve the connection strength of the motor cover 1 and the bottom frame 2 by connecting the motor cover 1 and the bottom frame 2 through the threaded member, thereby improving the fixing and sealing effect of the through-flow motor.

[0058] An air conditioner according to an embodiment of the present invention includes a base frame assembly, a tubular motor, and a housing. The base frame assembly is the base frame assembly of the present invention. The tubular motor is mounted within a motor cavity 3, with an output shaft of the tubular motor extending through an opening 31. Both the base frame assembly and the tubular motor are disposed within the housing.

[0059] According to the air conditioner of the embodiment of the present invention, the motor cover 1 and the bottom frame 2 enclose a motor cavity 3, and the motor cavity 3 has an opening portion 31 and a closed portion 32 arranged opposite each other along its axial direction, so that external airflow can be blocked by the closed portion 32 to prevent external airflow from entering the air duct. Since the first baffle 11 and the second baffle 21 abut to form the closed portion 32, the crossflow fan can be sealed only by the motor cover 1 and the bottom frame 2 without the need for additional parts. Therefore, the air conditioner of the embodiment of the present invention requires fewer parts to seal the crossflow motor, which is conducive to simplifying the assembly process and reducing production costs.
