[0028] See also Figures 3 to 7 As shown, according to an embodiment of the present invention, a volute front baffle is provided, including a front baffle body 106, on which an air inlet 101 corresponding to the air inlet side of the indoor fan 200 and an air outlet 102 corresponding to the air outlet side of the indoor fan 200 are constructed, and the air outlet 102 is integrally formed on the front baffle body 106, and the air outlet 102 is used to install a wind sweeping blade 300. For example, the front baffle body 106 is formed by one-piece injection molding. It can be understood that the frame wall of the air outlet 102 extends continuously in the circumferential direction of the air outlet 102, and the frame wall of the air outlet 102 has a mounting structure that matches the wind sweeping blade 300. In this technical solution, since the air outlet 102 is integrally formed on the front baffle body 106, there is no need to assemble a plurality of scattered components (sheet metal parts) to form a corresponding air outlet frame structure as in the prior art, thereby effectively avoiding the adverse effects of assembly errors generated during the assembly process on the installation accuracy of the wind sweeping blades and the time and labor costs consumed due to the assembly. Since the one-piece molding of the air outlet can maximize the shape and position dimensional accuracy and assembly efficiency of the air outlet, it can effectively prevent the axial position offset of the axial ends of the wind sweeping blade 300 caused by the large shape and position dimensional deviation in the prior art, thereby causing the wind sweeping blade to shake, get stuck, and make abnormal noise during operation, thereby effectively reducing after-sales quality problems.

[0029] Preferably, the air outlet 102 has a blade shaft end bearing plate 1021, and the blade shaft end bearing plate 1021 is provided with a first pivot connection hole 1022. Figure 3As shown, the blade shaft end bearing plate 1021 is arranged at the axial lower end position of the wind sweeping blade 300, and the axial lower end of the wind sweeping blade 300 can be inserted into the first pivot connection hole 1022, that is, the setting of the blade shaft end bearing plate 1021 can, on the one hand, play a role in positioning and bearing the wind sweeping blade 1021, and on the other hand, it can enhance the structural strength of the air outlet 102. On another hand, the blade shaft end bearing plate 1021 is integrally formed on the front partition body 106, which eliminates the difficulty and time-consuming disadvantage of separately setting up a corresponding bottom plate assembly in the prior art.

[0030] Furthermore, a blade mounting channel 103 is provided on the opposite side of the air outlet 102 and the blade shaft end bearing plate 1021. The blade mounting channel 103 extends along the axial direction of the wind sweeping blade 300 and passes through the inner and outer sides of the air outlet 102. The provision of the blade mounting channel 103 enables the installation of the wind sweeping blade 300 to be inserted in the direction in which it extends, thereby further simplifying the assembly efficiency of the wind sweeping blade 300. In order to further simplify the fixed installation of the shaft end of the wind sweeping blade 300, preferably, a blade shaft end blocking plate 104 is further provided on the blade mounting channel 103 to form a positioning for the wind sweeping blade 300 together with the blade shaft end bearing plate 1021, and the blade shaft end blocking plate 104 is detachably connected to the blade mounting channel 103. Preferably, the blade shaft end blocking plate 104 is snap-fitted to the blade mounting channel 103. Specifically, as Figure 4 and 5 As shown, the blade shaft end sealing plate 104 is provided with a plurality of hooks 1045, and the corresponding positions of the corresponding blade mounting channels 103 are provided with connecting holes that cooperate with the hooks 1045 to ensure the quick disassembly and assembly of the blade shaft end sealing plate 104. The blade shaft end sealing plate 104 also has a second pivot connection hole 1044, and the other shaft end of the wind sweeping blade 300 is inserted into the second pivot connection hole 1044. The design of the detachable blade shaft end sealing plate 104 can reduce the difficulty of assembling the wind sweeping blade 300 in the air outlet 102.

[0031] In order to ensure the coaxiality of the second pivot connection hole 1044 on the blade shaft end sealing plate 104 after assembly with the first pivot connection hole 1022, and thus ensure the smooth rotation of the wind sweeping blade 300, preferably, the blade shaft end sealing plate 104 includes a main board body 1041, and a coaxiality positioning column 1042 is provided on the main board body 1041, and a positioning hole 1031 is provided on the blade mounting channel 103 corresponding to the coaxiality positioning column 1042. When the coaxiality positioning column 1042 is inserted into the positioning hole 1031, the coaxiality of the second pivot connection hole 1044 and the first pivot connection hole 1022 is guaranteed. In essence, the coaxiality accuracy depends on the setting and processing accuracy of the positioning hole 1031. Since the positioning hole 1031 is preferably formed by injection molding in the application, its position accuracy will undoubtedly be greatly guaranteed. Furthermore, in order to limit the position of the blade shaft end sealing plate 104 in the axial direction of the wind sweeping blade 300, preferably, a positioning tongue 1043 is provided at the edge of the main board body 1041, and a positioning hole 1032 is provided on the blade mounting channel 103 corresponding to the positioning tongue 1043, which can prevent the blade shaft end sealing plate 104 from being too close to the wind sweeping blade 300 in the locking position (axial distance) and the axial pressure that may be applied to the wind sweeping blade 300, and the axial pressure here may cause the wind sweeping blade 300 to be stuck, jammed, and other adverse phenomena to occur.

[0032] The side of the blade shaft end bearing plate 1021 away from the wind sweeping blade 300 has an electrical box installation space 105. The design of this structure will be explained in conjunction with the electrical box 620 below and will not be repeated here.

[0033] According to an embodiment of the present invention, a window air conditioner is also provided, comprising a volute front baffle 100, wherein the volute front baffle 100 is the above-mentioned volute front baffle. Specifically, the air conditioner further comprises a middle baffle 400, a volute 500, and an indoor heat exchanger 701, wherein the volute front baffle 100 and the middle baffle 400 are located on both sides of the volute 500 to form an air duct, the indoor fan 200 is located in the air duct, and the indoor heat exchanger 701 is located on the air inlet side of the air inlet airflow of the air inlet 101.

[0034] The air conditioner further includes a chassis 610, the volute front baffle 100 and the middle baffle 400 are respectively detachably connected to the chassis 610, and further includes an electrical box 620, the electrical box 620 is detachably connected to the chassis 610, when the volute front baffle 100 has an electrical box installation space 105, the electrical box 620 is in the electrical box installation space 105, and the electrical box 620 is in the electrical box installation space 105, and the electrical box 620 is in the electrical box installation space 105. Figure 7As shown, in this technical solution, the electrical box 620 can be first assembled and fixedly connected with the chassis 610 when the air conditioner is assembled, and then the volute front partition 100 is assembled according to the preset position. Since the volute front partition 100 has an electrical box installation space 105, the installation of the electrical box 620 is no longer limited by the assembly molding state of the front partition and the middle partition as in the pull-out structure of the electrical box used in the prior art, which reduces the difficulty of assembling the electrical box 620. Preferably, when the volute front partition 100 has a blade shaft end bearing plate 1021, the electrical box 620 has a sweep motor mounting hole 621 on the side facing the blade shaft end bearing plate 1021, and the position of the sweep motor mounting hole 621 is adapted to the position of the first pivot connection hole 1022, and the output shaft of the sweep motor 702 is inserted into the first pivot connection hole 1022 through the sweep motor mounting hole 621 and connected to one shaft end of the sweep blade 300 to achieve the rotation of the sweep motor 702. The wind sweeping blade 300 is driven to rotate, and the wind sweeping motor 702 can be assembled with the electrical box 620 as a whole; the electrical box 620 has an inspection port 622 on the side facing the outside of the window air conditioner to facilitate the inspection of control panels such as the main control panel in the electrical box 620. Preferably, the inspection port 622 faces the vertically extending side wall of the window air conditioner (for example, based on the use orientation of the air conditioner, the inspection port 622 is opened on the left side wall of the window air conditioner, such as Figure 7 The inspection port 622 is provided with an electrical box sealing plate 623 on one side. In this technical solution, the electrical box sealing plate 623 provided on the inspection port 622 can form an enclosure for internal electrical components, and the opening 622 in the vertically extending side wall of the window air conditioner can improve the installation method of the electrical box from the existing push-pull type to the side-mounted type. The side-mounted electrical box can avoid the disadvantage of the push-pull electrical box in the prior art that it is unclear what damage may be caused to the corresponding connecting cables during the pushing or pulling process. When the side-mounted electrical box is used, it only needs to remove the air conditioner outer shell (not shown in the figure) or the electrical box sealing plate 623 to ensure that the devices and cables in the box are exposed to the field of vision to the greatest extent, thereby effectively avoiding potential damage to the cables or related devices. The two sides of the electrical box sealing plate 623 are respectively detachably connected (for example, bolted) to the front partition plate 100 and the middle partition plate 400 of the volute. The connection between the two sides of the electrical box sealing plate 623 and the front partition plate 100 and the middle partition plate 400 of the volute can ensure the stability of the relative position of the front partition plate 100 and the middle partition plate 400 of the volute.

[0035] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

The above are only preferred embodiments of the present invention.
