[0033] See also Figure 1 、 Figure 2 and Figure 3 An embodiment of the present application provides a protective cover 110, including a connected side panel 10 and a top panel 20, wherein the side panel 10 and the top panel 20 jointly enclose a protective space 30, and the side panel 10 extends along a first direction, and the angle between the first direction and the top panel 20 is an obtuse angle.

[0034] For example, when the protective cover 110 is used to protect an object such as a lock body, the side panels 10 of the protective cover 110 are generally parallel to the vertical direction, that is, the first direction is the vertical direction. It is understood that when the angle between the top panel 20 and the vertical direction is an obtuse angle, it means that the angle between the top panel 20 and the horizontal direction is an acute angle, that is, in this case, the top panel 20 is tilted relative to the horizontal direction.

[0035] The protective cover 110 provided in the embodiment of the present application can be set on the outer surface of the lock body to play a protective role, so as to prevent external water and / or detergents from entering the lock body and causing short circuit or corrosion of the lock body, thereby extending the service life of the lock body and further extending the service life of the electrical appliance using the lock body; the protective cover 110 includes a connected side plate 10 and a top plate 20, wherein the side plate 10 and the top plate 20 together enclose a protective space 30, and when in use, the lock body can be placed in the protective space 30 to protect the lock body. The extension direction of the side plate 10 of the protective cover 110 is The angle between the top plate 20 and the side plate 10 is an obtuse angle, that is, when the side plate 10 of the protective cover 110 is set in the vertical direction, a certain angle is formed between the top plate 20 of the protective cover 110 and the horizontal plane. At this time, the top plate 20 is set along the inclined direction, and the upper surface of the top plate 20 is an inclined surface. When water flows from above the protective cover 110 to the top plate 20 of the protective cover 110, the water will quickly flow away from the top plate 20 and flow downward along the outer surface of the side plate 10, thereby avoiding water accumulation on the top surface of the protective cover 110 and further enhancing the protective function of the protective cover 110.

[0036] See also Figure 1 、 Figure 2 and Figure 3 The protective cover 110 further includes a retaining wall 40 , which is located on a side of the top plate 20 away from the side plate 10 and connected to the top plate 20 , and a first opening 51 is defined on the retaining wall 40 .

[0037] It can be understood that by setting a retaining wall 40 above the top plate 20, a water flow channel can be enclosed by the retaining wall 40, so that water dripping onto the top plate 20 can flow along the water flow channel and out from the first opening 51, which is equivalent to converging the water flow and limiting the flow direction of the water flow, thereby preventing the water from flowing along the four edges of the top plate 20 and causing the water flow to splash onto the lock body protected by the protective cover 110. In addition, when the water flows along a single path, the water flowing down from the protective cover 110 is also easy to collect.

[0038] See also Figure 1 、 Figure 2 and Figure 3 The side panel 10 includes a first panel 11, a second panel 12 and a third panel 13. The second panel 12 and the third panel 13 are respectively arranged on both sides of the first panel 11 and are connected to the first panel 11. The first panel 11, the second panel 12 and the third panel 13 are all connected to the top panel 20, and the angle between the first panel 11 and the top panel 20 is an obtuse angle.

[0039] It can be understood that when the angle between the first plate body 11 and the top plate 20 is an obtuse angle, since the first plate body 11 extends in the vertical direction, it means that the end of the top plate 20 away from the first plate body 11 is higher than the end of the top plate 20 connected to the first plate body 11, so that the top plate 20 is inclined. Therefore, when water falls on the upper surface of the top plate 20, the water will flow down along the inclined surface due to gravity.

[0040] See also Figure 1 、 Figure 2 and Figure 3 , exemplarily, the second plate 12 and the third plate 13 are both perpendicular to the first plate 11 .

[0041] See also Figure 3 The edge of the top plate 20 includes a first edge 21, a second edge 22, a fourth edge 24 and a third edge 23 connected in sequence end to end, wherein the first edge 21 is connected to the first plate body 11, the second edge 22 is connected to the second plate body 12, the third edge 23 is connected to the third plate body 13, and the fourth edge 24 is arranged opposite to the first edge 21. The retaining wall 40 is arranged around the edge of the top plate 20 and forms the first opening 51 at the position corresponding to the first edge 21.

[0042] It can be understood that since the fourth side 24 of the top plate 20 is higher than the first side 21 of the top plate 20 and the second plate body 12, that is to say, the first side 21 is the lowest position on the top plate 20; when the retaining wall 40 forms the first opening 51 corresponding to the position of the first side 21, it means that the first opening 51 is set at the lowest position of the retaining wall 40 and the top plate 20, which is conducive to the rapid outflow of water falling on the upper surface of the top plate 20.

[0043] See also Figure 3 The retaining wall 40 includes a first wall 41, a second wall 42 and a third wall 43 connected in sequence, wherein the first wall 41 is connected to the second side 22 of the top plate 20, the second wall 42 is connected to the fourth side 24 of the top plate 20, and the third wall 43 is connected to the third side 23 of the top plate 20. The side of the first wall 41 facing away from the second wall 42 and the side of the third wall 43 facing away from the second wall 42 enclose the first opening 51.

[0044] Exemplarily, the first wall 41 and the second plate 12 are an integral structure. Exemplarily, the inner surface and the outer surface of the first wall 41 are flush with the inner surface and the outer surface of the second plate 12 respectively.

[0045] Exemplarily, the third wall 43 and the third plate 13 are an integral structure. Exemplarily, the inner surface and the outer surface of the third wall 43 are flush with the inner surface and the outer surface of the third plate 13 respectively.

[0046] Exemplarily, the protective cover 110 is an integrated structure, that is, the top plate 20, the side plate 10 and the retaining wall 40 are an integrated structure. Exemplarily, the protective cover 110 is prepared by an injection molding process.

[0047] For example, the protective cover 110 is made of a flame-retardant material, which can effectively control the fire when the lock body catches fire.

[0048] See also Figure 1 and Figure 2 A second opening 52 is formed on the side of the second plate 12 facing away from the first plate 11, the side of the third plate 13 facing away from the first plate 11, and the side of the top plate 20 facing away from the first plate 11, and the second opening 52 is connected to the protective space 30.

[0049] It is understandable that when the protective cover 110 is used to protect the lock body, the lock body can enter and exit the protective cover 110 through the second opening 52 , thereby facilitating the use of the protective cover 110 .

[0050] See also Figure 1 and Figure 2 The side of the first plate 11 away from the top plate 20, the side of the second plate 12 away from the top plate 20, and the side of the third plate 13 away from the top plate 20 enclose a third opening 53, and the third opening 53 is connected to the protective space 30.

[0051] It is understandable that when the protective cover 110 is used to protect the lock body, the lock body can enter and exit the protective cover 110 through the third opening 53 , thereby facilitating the use of the protective cover 110 .

[0052] See also Figure 1 and Figure 2 , illustratively, the second opening 52 and the third opening 53 are connected.

[0053] Exemplarily, the protective cover 110 further includes a magnetic member connected to the side panel 10 and / or the top panel 20 .

[0054] It can be understood that when the material of the object protected by the protective cover 110 (such as a lock body, etc.) contains magnetic materials (such as iron, nickel, and cobalt, etc.), the magnetic attraction between the magnetic element and the protected object can be used to achieve a fixed connection between the protective cover 110 and the protected object, thereby preventing the protective cover 110 from slipping off the surface of the protected object and losing the protective effect.

[0055] In some embodiments, a magnetic element is provided on at least one location of the interior, inner surface, and outer surface of the side panel 10 .

[0056] In some embodiments, a magnetic element is provided on at least one location of the interior, inner surface, and outer surface of the top plate 20 .

[0057] See also Figure 4 and Figure 5 An embodiment of the present application further provides a lock device 100, comprising a lock body 120 and a protective cover 110, wherein at least a portion of the lock body 120 is located in the protective space 30 of the protective cover 110, and the protective cover 110 is the protective cover 110 in any of the above embodiments.

[0058] See also Figure 4 and Figure 5 The protective cover 110 can cover a portion of the outer surface of the lock body 120 .

[0059] See also Figure 5The lock body 120 is provided with a lock opening 121, which is used to cooperate with the lock hook to achieve locking and fixation between the lock body 120 and the lock hook. The lock opening 121 is set in an area of the lock body 120 that is not covered by the protective cover 110.

[0060] Exemplarily, the lock device 100 is an electronic lock.

[0061] An embodiment of the present application further provides a washing machine, comprising the locking device 100 in any of the above embodiments.

[0062] Exemplarily, the washing machine is a drum washing machine.
