DETAILED DESCRIPTION

[0026] See also Figures 3 to 7As 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, the air outlet 102 is integrally formed on the front baffle body 106, the air outlet 102 is used to install a wind sweeping blade 300, a first pivot connection hole 1022 pivotally connected to an axial first end of the wind sweeping blade 300 is provided on the top wall of the air outlet 102, a blade shaft end bearing plate 1021 pivotally connected to an axial second end of the wind sweeping blade 300 is provided on the bottom wall of the air outlet 102, and the blade shaft end bearing plate 1021 is detachably connected to the bottom wall of the air outlet 102. 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. The detachable connection between the blade shaft end bearing plate 1021 and the bottom wall of the air outlet 102 makes the assembly process of the wind sweeping blade 300 into the air outlet 102 more convenient.

[0027] Preferably, a mounting groove 103 is constructed on the bottom wall of the air outlet 102, and the mounting groove 103 extends a first distance toward a side away from the wind sweeping blade 300. The first distance can be understood, and its specific numerical value should at least ensure that the straight-line distance between the bottom wall of the mounting groove 103 and the opening of the first pivot connection hole 1022 is greater than the maximum axial length of the wind sweeping blade 300, so as to ensure that the wind sweeping blade 300 can be smoothly and conveniently installed in the air outlet 102. An axial hole is also provided on the mounting groove 103, so that the power output end of the wind sweeping motor 702 can pass through and be sleeved with the axial second end of the wind sweeping blade 300, and the blade shaft end bearing plate 1021 is slidably connected in the mounting groove 103. Specifically, slide grooves are provided on the groove walls on the opposite sides of the installation groove 103, and protruding blocks 1025 are provided on the opposite sides of the blade shaft end bearing plate 1021. The protruding blocks 1025 can be inserted into the slide grooves along the through direction of the air outlet 102. The setting of the installation groove 103 will not cause the structural continuity of the air outlet 102 in the circumferential direction, thereby ensuring the structural rigidity of the volute front baffle 100 and further ensuring its structural stability. The sliding design of the slide groove and the protruding block 1025 can provide higher installation accuracy. After the blade shaft end bearing plate 1021 is assembled in the installation groove 103, the structural strength of the bottom wall of the air outlet 102 will not be substantially reduced due to the installation groove 103. of the design. Of course, as an optional implementation form, a snap-on connection method can also be used between the blade shaft end bearing plate 1021 and the mounting groove 103. This method can provide convenience for assembly, but due to considerations of the elastic margin of the snap-on connection, it reduces the supporting capacity of the axial second end (that is, the lower end) of the wind-sweeping blade 300 to a certain extent. The choice of the sliding connection method adopted in the present application can facilitate assembly while relying on the advantages of the sliding connection in terms of matching accuracy to enhance the supporting capacity (after the wind-sweeping blade 300 is actually assembled, most of its own weight will be applied to the bottom wall of the air outlet 102. For this reason, it is particularly important to adopt this technical solution in the present application).

[0028] Furthermore, the shaft hole opening is also provided with a first side bearing 1032, and the blade shaft end bearing plate 1021 is provided with a second side bearing 1023. When the blade shaft end bearing plate 1021 is assembled in the mounting groove 103, the first side bearing 1032 and the second side bearing 1023 jointly form a pivot support for the axial second end of the wind sweeping blade 300. At this time, preferably, the blade shaft end bearing plate 1021 is also configured with a first positioning hole 1024, and the mounting groove 103 is also configured with a second positioning hole (not shown in the figure). The positions of the first positioning hole 1024 and the second positioning hole match each other. The purpose of setting the first positioning hole 1024 and the second positioning hole is, on the one hand, to connect the blade shaft end bearing plate 1021 and the mounting groove 103, and on the other hand, to ensure the coaxiality of the first side bearing 1032 and the second side bearing 1023 with the wind sweeping blade 300 after being matched in pairs.

[0029] 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.

[0030] 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, and the volute front baffle 100, the middle baffle 400, and the volute 500 together form an air duct, wherein 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.

[0031] 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 a 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 like the electrical box pull-out structure used in the prior art, which reduces the difficulty of assembling the electrical box 620. Preferably, when the volute front baffle 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 shaft hole through the sweep motor mounting hole 621 and connected to an axial end of the sweep blade 300 to drive the rotation of the sweep blade 300, and the sweep 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 the control panel components such as the main control panel in the electrical box 620, and 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 inspection port 622 is opened on the vertically extending side wall of the window air conditioner so that the installation method of the electrical box can be improved 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.
