[0028] An embodiment of the present application provides an electrical appliance cover 10, see Figures 2 to 5 The electrical appliance cover 10 includes a cover body 11 and a plurality of fixing portions 12 disposed on the cover body 11 .

[0029] The cover body 11 has opposite first end face 11a and second end face 11b. Each fixing part 12 protrudes from the second end face 11b, and the side of the fixing part 12 facing away from the second end face 11b has a third end face 12a. The third end faces 12a of all the fixing parts 12 are located in the same virtual plane parallel to the first end face 11a, so that when multiple electrical appliance covers 10 are in a stacked state, the third end faces 12a of the fixing parts 12 of one electrical appliance cover 10 are in contact with the first end face 11a of an adjacent another electrical appliance cover 10.

[0030] The stacked state means that multiple electrical appliance covers 10 are stacked one above the other in sequence along a certain direction.

[0031] The purpose of stacking multiple electrical appliance covers 10 is to place the electrical appliance covers 10 during the production and assembly stage, so as to facilitate grasping by manual or automatic material taking devices.

[0032] The virtual plane is an imaginary plane. The third end faces 12a of all the fixing parts 12 being located in the same virtual plane parallel to the first end face 11a means that the third end faces 12a of all the fixing parts 12 can coincide with the same imaginary plane, and this imaginary plane is parallel to the first end face 11a. That is to say, the heights of the fixing parts 12 protruding from the second end face 11b are the same, so that the third end faces 12a of all the fixing faces are located in the same plane.

[0033] The purpose of the virtual plane being parallel to the first end face 11a is that in the stacked state, the third end faces 12a of the fixing parts 12 of one electrical appliance cover 10 can be in contact with the first end face 11a of an adjacent another electrical appliance cover 10. That is to say, the fixing parts 12 of one electrical appliance cover 10 can support on the first end face 11a of an adjacent another electrical appliance cover 10.

[0034] Another embodiment of the present application provides an air conditioner indoor unit. Please refer to Figure 1 , the air conditioner indoor unit includes a front frame 20 having an installation window 20a and the electrical appliance cover 10 described in any embodiment of the present application, and the electrical appliance cover 10 is arranged at the installation window 20a.

[0035] The installation window 20a is used for maintenance personnel to perform maintenance on the electrical control components and / or other electrical components inside the front frame 20. That is to say, the maintenance personnel can observe the electrical control components and / or other electrical components through the installation window 20a.

[0036] The electrical appliance cover 10 is used to block the installation window 20a, so as to play a protective role for the electrical control components and / or other electrical components.

[0037] Specifically, the electrical appliance cover plate 10 shields the installation window 20a through the cover plate body 11. When the electrical appliance cover plate 10 is disposed at the installation window 20a, the first end face 11a of the cover plate body 11 faces the outside of the face frame 20, while the second end face 11b faces the inside of the face frame 20.

[0038] A plurality of fixing portions 12 are used for connecting with the face frame 20, that is, the electrical appliance cover plate 10 is connected with the face frame 20 through the fixing portions 12. Each fixing portion 12 protrudes from the second end face 11b, which can facilitate the connection between the fixing portion 12 and the face frame 20.

[0039] Another embodiment of the present application further provides an air conditioner, including the air conditioner indoor unit described in any embodiment of the present application.

[0040] In the electrical appliance cover plate 10 of the embodiment of the present application, a plurality of fixing portions 12 are provided on the cover plate body 11. The fixing portions 12 protrude from the second end face 11b of the cover plate body 11, and the third end face 12a of the fixing portion 12 is located in the same virtual plane parallel to the first end face 11a. When a plurality of electrical appliance cover plates 10 are in a stacked state, the third end face 12a of each fixing portion 12 of one electrical appliance cover plate 10 contacts the first end face 11a of an adjacent another electrical appliance cover plate 10. Thus, not only can one electrical appliance cover plate 10 be supported on the first end face 11a of an adjacent another electrical appliance cover plate 10 through a plurality of fixing portions 12, but also the contact stability between two adjacent electrical appliance cover plates 10 can be improved, so that it can preferably prevent the plurality of electrical appliance cover plates 10 from being skewed or toppled in the stacked state, and further, the stable stacking of the plurality of electrical appliance cover plates 10 can be realized.

[0041] In addition, taking the automatic material taking device to take the electrical appliance cover plate 10 as an example, a plurality of electrical appliance cover plates 10 can be stacked in a manner that the first end face 11a faces upward and the second end face 11b faces downward. Since the protruding portion 111 protrudes from the second end face 11b, and the second end face 11b of one electrical appliance cover plate 10 in the stacked state faces the first end face 11a of an adjacent another electrical appliance cover plate 10, therefore, whether the automatic material taking device sequentially grabs single electrical appliance cover plates 10 for stacking or sequentially grabs single electrical appliance cover plates 10 from the plurality of electrical appliance cover plates 10 in the stacked state, the automatic material taking device can adhere to the first end face 11a through a suction cup to grab the corresponding electrical appliance cover plate 10, that is to say, the first end face 11a can be used to cooperate with the automatic material taking device, which is beneficial to realizing the automatic assembly of the electrical appliance cover plate 10, and further can improve the assembly efficiency.

[0042] It should be noted that the electrical appliance cover plate 10 of the embodiment of the present application is not limited to being installed on the face frame 20 of the air conditioner indoor unit, and other electrical equipment can also use the electrical appliance cover plate 10 of the embodiment of the present application.

[0043] In one embodiment, please refer toFigures 1 to 5 , at least some of the plurality of fixing parts 12 can be buckles 121. That is to say, the electrical appliance cover plate 10 can be snap-connected to the front frame 20 through the buckles 121, so as to improve the assembly efficiency of the electrical appliance cover plate 10 and the front frame 20 and reduce the production cost.

[0044] Exemplarily, please refer to Figures 4 to 7 , the cover plate body 11 can have a side wall surface 11c located between the first end surface 11a and the second end surface 11b, and the buckle 121 protrudes from the side wall surface 11c. By making the buckle 121 protrude from the side wall surface 11c, the part of the buckle 121 protruding from the side wall surface 11c can extend into the inside of the front frame 20 from the installation window 20a and abut against the front frame 20, so as to play a fixing role.

[0045] In one embodiment, please refer to Figures 2 to 6 , at least some of the plurality of fixing parts 12 can be mounting posts 122, the electrical appliance cover plate 10 has a mounting hole 10a, and the mounting hole 10a penetrates through the mounting post 122 and the cover plate body 11.

[0046] The mounting hole 10a is used to tightly connect the electrical appliance cover plate 10 to the front frame 20. That is to say, the front frame 20 has a fixing hole corresponding to the mounting hole 10a, and fasteners such as screws and bolts are inserted through the mounting hole 10a and the fixing hole, so as to realize the tight connection between the electrical appliance cover plate 10 and the front frame 20.

[0047] Exemplarily, please refer to Figure 7 , the mounting hole 10a can include a first section 10a1 penetrating through the first end surface 11a and a second section 10a2 penetrating through the third end surface 12a of the mounting post 122, and the aperture of the first section 10a1 is larger than the aperture of the second section 10a2.

[0048] By making the first section 10a1 of the mounting hole 10a penetrate through the first end surface 11a and making the aperture of the first section 10a1 larger than the aperture of the second section 10a2, the head of the fastener can be arranged in the first section 10a1, and the rod part penetrates into the second section 10a2. Preferably, the height of the head of the fastener is less than the depth of the first section 10a1 in the penetrating direction of the mounting hole 10a, so that the head of the fastener can be completely located in the first section 10a1, preventing the head of the fastener from protruding from the first end surface 11a, thereby ensuring the flatness of the electrical appliance cover plate 10.

[0049] Please continue to refer to Figure 7, on the projection plane perpendicular to the penetrating direction of the mounting hole 10a, the projection of the first section 10a1 can be located within the projection area surrounded by the outer contour of the third end face 12a. That is to say, the diameter of the first section 10a1 of the mounting hole 10a is smaller than the diameter of the third end face 12a of the mounting post 122. When multiple electrical appliance covers 10 are in a stacked state, the third end face 12a of the mounting post 122 of the first cover contacts the first end face 11a of the adjacent second cover, and the third end face 12a of the mounting post 122 of the first cover covers the first section 10a1 of the mounting hole 10a of the second cover, so as to make the stacked state of multiple electrical appliance covers 10 more stable.

[0050] In one embodiment, please refer to Figure 3 、 Figure 5 and Figure 6 , some of the fixing parts 12 among the multiple fixing parts 12 can be buckles 121, and the other part of the fixing parts 12 are mounting holes 10a and mounting posts 122. The electrical appliance cover 10 has a mounting hole 10a penetrating through the mounting post 122 and the cover body 11. The buckles 121 and the mounting posts 122 are respectively located on opposite sides of the cover body 11.

[0051] By making the buckles 121 and the mounting posts 122 respectively located on opposite sides of the cover body 11, the buckles 121 and the mounting posts 122 can respectively support opposite sides of the cover body 11, which can not only enhance the stacking stability of multiple electrical appliance covers 10 in a stacked state, but also enhance the connection stability between the electrical appliance cover 10 and the face frame 20.

[0052] Exemplarily, when the electrical appliance cover 10 is assembled with the face frame 20, the buckle 121 can be first snapped onto the face frame 20 to align the mounting hole 10a with the fixing hole on the face frame 20, and then the fastener can be passed through the mounting hole 10a and the fixing hole, so as to facilitate the installation of the electrical appliance cover 10.

[0053] In one embodiment, please refer to Figures 2 to 6 , the cover body 11 can have a protruding portion 111. The protruding portion 111 has a wall body 1111 protruding from the second end face 11b and two grooves 111a spaced apart from each other surrounded by the wall body 1111. The portion of the wall body 1111 between the two grooves 111a forms a holding portion 11111.

[0054] The holding portion 11111 can be used for maintenance personnel to grab the electrical appliance cover 10 during the process of disassembling and assembling the electrical appliance cover 10.

[0055] Specifically, since the wall body 1111 protrudes from the second end face 11b, and the groove 111a is formed by surrounding the wall body 1111, the groove 111a faces the first end face 11a of the cover plate body 11. When the electrical appliance cover plate 10 is arranged on the face frame 20, the groove 111a faces the outside of the face frame 20. When maintenance personnel need to disassemble the electrical appliance cover plate 10 to perform maintenance on the electric control component and / or other electrical components, the maintenance personnel can first release the connection between the fixing part 12 and the face frame 20, and then grab the holding part 11111 by hand to take out the electrical appliance cover plate 10. After the maintenance is completed, the maintenance personnel can also grab the holding part 11111 and reinstall the electrical appliance cover plate 10 onto the face frame 20, so that it is convenient for the maintenance personnel to grab the electrical appliance cover plate 10, and further facilitates the disassembly and installation of the electrical appliance cover plate 10.

[0056] In addition, since the protruding part 111 protrudes from the second end face 11b, this setting method can ensure that the side of the cover plate body 11 with the first end face 11a is flat, thus better avoiding the holding part 11111 from affecting the material taking of the electrical appliance cover plate 10 by the automatic material taking device.

[0057] Further, please refer to Figure 2 、 Figure 4 and Figure 7 The part of the holding part 11111 located in each groove 111a can have holding lines 11111a.

[0058] The holding lines 11111a are used to increase the friction when the maintenance personnel grab the holding part 11111, facilitating the maintenance personnel to grab.

[0059] The structure of the holding lines 11111a is not limited. Exemplarily, the holding lines 11111a can protrude from the side wall of the holding part 11111. In another embodiment, the holding lines 11111a can be formed by the inward depression of the side wall of the holding part 11111.

[0060] The shape of the holding lines 11111a is not limited. Exemplarily, the holding lines 11111a can be in the shape of a straight line, a wave shape, or a dot shape, etc.

[0061] Please continue to refer to Figure 2 、 Figure 4 and Figure 7 The part of the holding part 11111 located in at least one of the grooves 111a can have a plurality of holding lines 11111a arranged at intervals.

[0062] Since the holding portion 11111 is formed by the portion of the wall 1111 located between the two grooves 111a, that is, the opposite sides of the holding portion 11111 are respectively located in the two grooves 111a. Therefore, one side of the holding portion 11111 may have the holding pattern 11111a while the other side does not have the holding pattern 11111a, or the portions of the holding portion 11111 located in the two grooves 111a may have the holding pattern 11111a.

[0063] The multiple gripping lines 11111a are arranged at intervals, which can increase the coverage area of the multiple gripping lines 11111a and facilitate gripping by maintenance personnel.

[0064] In one embodiment, please refer to Figures 2 to 4 The wall body 1111 may include a side wall 11112 and a bottom wall 11113 that enclose a corresponding groove 111a, the bottom wall 11113 is located on the side of the side wall 11112 away from the second end face 11b, and a notch 111a1 is formed on the side opposite to the groove 111a and the bottom wall 11113, a protruding height H2 of the bottom wall 11113 protruding from the second end face 11b is greater than a protruding height H1 of the fixing portion 12 protruding from the second end face 11b, and an outer dimension of the notch 111a1 is greater than an outer dimension of the bottom wall 11113, so that when multiple electrical cover plates 10 are in a stacked state, the wall body 1111 of one electrical cover plate 10 can be plugged into and matched with the two grooves 111a of another electrical cover plate 10.

[0065] The portion of the wall body 1111 inserted into the two grooves 111 a may or may not contact the inner wall surface of the groove 111 a.

[0066] Please continue reading Figures 2 to 4 The wall body 1111 may have two side walls 11112 and two bottom walls 11113, so that one side wall 11112 and one bottom wall 11113 are a group to form a groove 111a. When multiple electrical appliance covers 10 are in a stacked state, a group of side walls 11112 and bottom walls 11113 are plugged into one of the two grooves 111a.

[0067] By making the protruding height of the bottom wall 11113 protruding from the second end face 11b greater than the protruding height of the fixing portion 12 protruding from the second end face 11b, when the third end face 12a of the fixing portion 12 of one electrical appliance cover plate 10 contacts the first end face 11a of another adjacent electrical appliance cover plate 10 in a stacked state of multiple electrical appliance cover plates 10, at least part of the structure of the bottom wall 11113 can extend into the two grooves 111a of another adjacent electrical appliance cover plate 10. That is to say, part of the structure of the bottom wall 11113 can be inserted into the groove 111a, or the entire bottom wall 11113 can be completely inserted into the groove 111a. In addition, it can be understood that part of the structure of the side wall 11112 is also inserted into the groove 111a.

[0068] Exemplarily, please refer to Figure 4 , one end of the side wall 11112 close to the bottom wall 11113 can be inclined towards the direction close to the groove 111a to reduce the external dimension of the bottom wall 11113, so that the external dimension of the bottom wall 11113 is smaller than the external dimension of the notch 111a1, so that the wall body 1111 of one electrical appliance cover plate 10 can be inserted into the two grooves 111a of another electrical appliance cover plate 10 through the notch 111a1.

[0069] By making the wall body 1111 of one electrical appliance cover plate 10 inserted and matched with the two grooves 111a of another electrical appliance cover plate 10, the wall body 1111 and the groove 111a can be matched to limit the adjacent two electrical appliance cover plates 10, and prevent the multiple electrical appliance cover plates 10 in the stacked state from sliding relative to each other and causing skewing or toppling.
