[0002] A washing machine is a device that automatically washes bowls, chopsticks, plates, dishes, knives, forks and other tableware. The fully automatic washing machines on the market can be divided into two categories: household and commercial. Household fully automatic washing machines are only suitable for households, and are mainly cabinet-type, desktop-type, sink-integrated and integrated types.

[0003] In washing machine products, air is blown into the inner cavity of the washing machine during the drying stage to improve the drying effect of the washing machine. It is generally composed of a fan, an air duct and a heating device (or a drying device). It is mainly used to dry the tableware after the washing machine completes the cleaning.

[0004] After dishes are dried, some water remains inside the washing machine, which can easily breed bacteria and create odors. A poor external environment can also further deteriorate the air quality inside the chamber. To ensure clean air inside the washing machine and prevent odor and bacterial growth, sterilization devices are used to sterilize the chamber. Currently, most sterilization methods use silver ion sterilization, electric heating, or ultraviolet light.

[0005] In the related art, the drying device and the sterilizing device are respectively provided with protective covers, however, this approach is costly and complicated to install, which affects the assembly efficiency of the cleaning machine. Utility Model Content

[0006] The present application hopes to provide a protective cover and a cleaning machine, which are at least used to improve the assembly efficiency of the cleaning machine.

[0035] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] At least see Figure 1-Figure 7 As shown, the present invention provides a protective cover 5, comprising: a protective cover body having a cavity 501. The protective cover body 51 forms an opening of the cavity 501 on a first side, and forms an end wall of the cavity 501 on a second side, with the first side and the second side being arranged opposite to each other.

[0038] The protective cover body 51 has two notches arranged opposite to each other in the circumferential direction. The opening direction of the notches is the same as the opening direction of the cavity 501. The two notches are connected to form an avoidance groove 54 for the water supply pipe 4 to pass through.

[0039] The end wall is recessed from the second side to the first side to form a recessed portion 53 . The recessed portion 53 extends in the same direction as the avoidance groove 54 and divides the cavity 501 into a first sub-cavity 51 and a second sub-cavity 52 that are arranged side by side and independent of each other.

[0040] When the protective cover 5 is used in a cleaning machine, which can be a dishwasher, the first sub-cavity 51 can be provided with a fan 2 and a heating tube 6, and the second sub-cavity 52 can be provided with a disinfection lamp 3. Of course, the second sub-cavity 52 can also be provided with a fan 2 and a heating tube 6, and the first sub-cavity 51 can be provided with a disinfection lamp 3. The following examples are based on the example of providing a fan 2 and a heating tube 6 in the first sub-cavity 51 and a disinfection lamp 3 in the second sub-cavity 52.

[0041] Since the first sub-cavity 51 and the second sub-cavity 52 are independent of each other, the mutual influence between the fan 2, the heating tube and the disinfection lamp 3 can be suppressed.

[0042] In addition, by providing the recessed portion 53, the overall rigidity and strength of the protective cover body can be improved, thereby preventing the first sub-cavity 51 and the second sub-cavity 52 from being deformed due to the deformation of the protective cover body, and making it impossible to install the protective cover 5 on the rear wall panel of the cleaning machine, so as to cover the fan 2 and the heating tube 6 in the first sub-cavity 51 and the disinfection lamp 3 in the second sub-cavity 52 respectively, or to prevent the blades of the fan 2 from scratching against the cavity wall of the first sub-cavity 51 during rotation, or to prevent the second sub-cavity 52 from deforming and contacting the disinfection lamp 3 installed therein, causing damage to the disinfection lamp 3.

[0043] The protective cover body can be made of, but is not limited to, stainless steel.

[0044] The protective cover body can be made of, but is not limited to, sheet metal processing or stamping processing.

[0045] For example, the protective cover body is formed using a stamping process. A stainless steel sheet to be stamped is placed on a stamping device, and the punch presses the sheet, thereby forming the protective cover body having a recessed portion 53, a relief groove 54, a first sub-cavity 51, and a second sub-cavity 52. ​​This allows the protective cover 5 to be integrally formed, making processing simple and convenient, and helping to reduce production costs.

[0046] In addition, in actual application, in order to improve the cleaning ability of the cleaning machine, at least two spray arms are generally set up in the upper and lower parts of the cleaning machine, and are connected through the water pipe 4 set in the inner tank 1 to supply water to different spray arms at the same time. Figure 1 、 Figure 2 As shown, the water pipe 4 is arranged in a vertical direction and is located on the rear wall plate 11 of the inner tank 1. The protection cover 5 of this solution is provided with an avoidance groove 54, which allows the water pipe 4 to pass through the protection cover 5 through the avoidance groove 54, so that the water pipe 4 can supply water to the upper spray arm and other components, so that the installation of the protection cover 5 and the water pipe 4 does not affect each other.

[0047] As an implementation method, the area on the end wall corresponding to the first sub-cavity 51 is the first end wall 515, and the first end wall 515 has an air inlet area 5104, and the air inlet area 5104 is provided with an air inlet hole 5101.

[0048] A first side wall is provided around the first end wall 515 . An air outlet 5102 is provided on the first side wall. Along the flow direction of the fluid, the air outlet 5102 is located downstream of the air inlet 5101 .

[0049] like Figure 3 As shown, the recessed portion 53 is provided in the middle portion of the end wall in the left-right direction. The recessed portion 53 may be a long groove. The long groove may extend vertically and penetrate the protective cover body, that is, the upper and lower ends of the long groove are open. Of course, it is understood that the groove portion 53 may have other structures, which are not listed in this embodiment.

[0050] The long groove divides the end wall into two parts, wherein the area on the left side of the long groove is the first end wall 515 , and the area on the right side of the long groove is the second end wall 525 .

[0051] As an implementation, three of the four side edges around the first end wall 515 extend from the second side to the first side to form first side wall panels, and the first side wall panels are sequentially connected to form the first side wall. At least one of the first side wall panels has an air outlet 5102 formed therein, and one of the first side wall panels is located away from the second sub-cavity 52.

[0052] Among them, Figure 3 As shown, among the four circumferential sides of the first end wall 515, three sides extend in the direction from the second side to the first side to form the first left side wall panel 514, the first lower side wall panel 512, and the first upper side wall panel 511 respectively. The first left side wall panel 514, the first lower side wall panel 512, and the first upper side wall panel 511 are connected in sequence to form the first side wall.

[0053] Of the four circumferential sides of the first end wall 515, the remaining sides extend in the same direction as the avoidance groove 54 to form a first connecting wall plate 513. The first connecting wall plate 513, together with the first left side wall plate 514, the first lower side wall plate 512, and the first upper side wall plate 511, form the first sub-cavity 51. The first connecting wall plate 513 at least forms a portion of the recessed portion 53, and the first sub-cavity 51 and the recessed portion 53 share the first connecting wall plate 513.

[0054] Similarly, if Figure 3As shown, among the four circumferential sides of the second end wall 525, three sides extend in the direction from the second side to the first side to form the second right side wall panel 523, the second lower side wall panel 522, and the second upper side wall panel 521 respectively. The second right side wall panel 523, the second lower side wall panel 522, and the second upper side wall panel 521 are connected in sequence to form the second side wall.

[0055] Of the four circumferential sides of the second end wall 525, the remaining sides extend in the same direction as the avoidance groove 54 to form a second connecting wall plate 524. The second connecting wall plate 524, together with the second right side wall plate 523, the second lower side wall plate 522, and the second upper side wall plate 521, form the aforementioned second sub-cavity 52. ​​The second connecting wall plate 524 at least forms a portion of the recessed portion 53, and the second sub-cavity 52 and the recessed portion 53 share the second connecting wall plate 524.

[0056] Among them, Figure 3 As shown, a fan 2 is disposed in the first sub-cavity 51. Correspondingly, an air inlet area 5104 is provided on the first end wall 515. This air inlet area 5104 is provided with a plurality of air inlet holes 5101. The air inlet area 5104 can be positioned directly opposite the fan 2 to shorten the air inlet path, reduce air inlet resistance, and increase air intake. The plurality of air inlet holes 5101 can be arranged in a circular array or a rectangular array.

[0057] In some embodiments, because the first left side panel 514 is located away from the second sub-cavity 52, a plurality of air outlet holes 5102 are provided on the first left side panel 514. The plurality of air outlet holes 5102 can be arranged in a circular array or a rectangular array. The first connecting panel 513, however, is located closer to the second sub-cavity 52 and does not have any air outlet holes 5102. This ensures that none of the air outlet holes 5102 face the second sub-cavity 52, thereby minimizing the impact of the fan 2 on the disinfection lamp 3.

[0058] In some embodiments, the first left side panel 514, the first lower side panel 512, and the first upper side panel 511 are each provided with a plurality of air outlet holes 5102, and the plurality of air outlet holes 5102 can be arranged in a circular array or a rectangular array. In other words, the first side wall is provided with a plurality of air outlet holes 5102.

[0059] Of course, in some embodiments, any three of the four side edges around the first end wall 515 extend in the direction from the second side to the first side to form third side wall panels, and each third side wall panel is connected in sequence to form the above-mentioned first side wall, and each third side wall panel is provided with an air outlet 5102.

[0060] In actual use, air outside the protective cover body enters the first sub-cavity 51 through the air inlet 5101 on the first end wall 515 under the action of the rotating blades of the fan 2. The air in the first sub-cavity 51 is then centrifugally ejected by the blades of the fan 2, and then heated by the heating tube 6 before being discharged through the air outlet 5102. Since the air is heated by the heating tube 6, the hot air will float upward. If the wind pressure at the air outlet is low, this will affect the uniformity of the hot air flow in the inner liner 1.

[0061] Based on this, the total area of ​​the air outlet holes 5102 of any one of the first left side wall panel 514, the first lower side wall panel 512, and the first upper side wall panel 511 is smaller than the total area of ​​the air inlet holes 5101 in the first end wall 515. The larger wind pressure can transport the hot air to all corners of the inner liner 1 faster, so that more hot air can be discharged from the bottom of the protective cover 5.

[0062] In one embodiment, Figure 3 As shown, the air inlet area 5104 is offset on the first end wall 515 in a direction away from the second sub-cavity 52. ​​In this way, each air outlet 5102 is further away from the second sub-cavity 52, further suppressing the influence of the fan 2 on the disinfection lamp 3.

[0063] In one embodiment, at least one first press profile 5103 is provided on the first end wall 515 around the air inlet area 5104 and is recessed toward the cover opening of the protective cover 5 .

[0064] Specifically, if Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, the first press profile 5103 can be an annular groove that is recessed from front to back in a local area of ​​the first end wall 515. Alternatively, the first press profile 5103 can be an annular protrusion that is protruded from back to front in a local area of ​​the first end wall 515.

[0065] A first profile 5103 is provided on the first end wall 515, surrounding the air inlet area 5104. The first profile 5103 enhances the rigidity and strength of the first end wall 515, ensuring its flatness, thereby reducing the probability of the blades of the fan 2 rubbing against the first end wall 515 due to deformation of the first end wall 515.

[0066] It should be noted that when the protective cover body is formed by a stamping process, the first pressing profile 5103 can be formed by stamping.

[0067] In one embodiment, along the direction from the first side to the second side, the height of the portion of the first end wall 515 corresponding to the air inlet area 5104 is higher than the height of the remaining portion of the first end wall 515 .

[0068] This increases the distance between the air inlet area 5104 and the blades of the fan 2 , and reduces the probability that the blades of the fan 2 will scrape against the first end wall 515 due to deformation of the first end wall 515 .

[0069] As an implementable method, a first light exit hole 5201 is provided on the second end wall 525 of the second sub-cavity 52. ​​The first light exit hole 5201 is an elongated hole with second pressed parts 5204 provided at both ends of the elongated hole and multiple second light exit holes 5202 provided on both sides of the elongated hole.

[0070] Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, a disinfection lamp 3 is provided in the second sub-cavity 52 , and the disinfection lamp 3 can be arranged along the left and right directions. Correspondingly, a first light exit hole 5201 and a second light exit hole 5202 are provided on the second end wall 525 .

[0071] The first light exit hole 5201 is an elongated hole, and the extending direction of the elongated hole is the same as the setting direction of the disinfection lamp 3, and the elongated hole corresponds to the disinfection lamp 3. The second light exit hole 5202 can be located in the area of ​​the second end wall 525 close to the second lower side wall plate 522 and in the area of ​​the second end wall 525 close to the second upper side wall plate 521.

[0072] The first light exit hole 5201 and the second light exit hole 5202 make the light exit area on the second end wall 525 larger, which helps the disinfection lamp 3 to emit more light, thereby improving the sterilization effect.

[0073] The first light exit hole 5201 and the second light exit hole 5202 are offset on the second end wall 525 toward the first sub-cavity 51. In this way, the light from the disinfection lamp 3 can reach directly in front of the first sub-cavity 51, thereby expanding the coverage area of ​​the light.

[0074] In addition, a second press profile 5204 is provided on the second end wall 525 , and two second press profiles 5204 are respectively located at two ends of the first light exit hole 5201 .

[0075] Specifically, if Figure 3 and Figure 6 As shown, the second protrusion 5204 can be a groove that is concave from front to back along a portion of the second end wall 525. Alternatively, the first protrusion 5103 can be a protrusion that is convex from back to front along a portion of the first end wall 515. The groove and protrusion can be in the shape of an arcuate strip. Of course, it is understood that the groove and protrusion can also have other shapes, which are not listed in this embodiment.

[0076] The second profile 5204 improves the rigidity and strength of the second end wall 525, helps maintain its flatness, and reduces the probability of damage to the disinfection lamp 3 due to deformation of the second end wall 525. Furthermore, the second profile 5204 shields the end of the disinfection lamp 3, improving the aesthetics of the inner container 1.

[0077] It should be noted that when the protective cover body is formed by a stamping process, the second pressing profile 5204 can be formed by stamping.

[0078] Among them, Figure 3 and Figure 6 As shown, at least one circle of third profile 5205 is provided on the second end wall 525. The second profile 5204, the first light exit hole 5201 and the second light exit hole 5202 are respectively located in the area surrounded by the third profile 5205.

[0079] It should be noted that the structure of the third press profile 5205 can refer to the structural description of the first press profile 5103, so it will not be described in detail.

[0080] The provision of the third profile 5205 can improve the rigidity and strength of the second end wall 525 , help the second end wall 525 to ensure its flatness, and reduce the probability of the disinfection lamp 3 being damaged due to deformation of the second end wall 525 .

[0081] It should be noted that when the protective cover body is formed by a stamping process, the third press profile 5205 can be formed by stamping.

[0082] The second lower side panel 522 , the second right side panel 523 and the second upper side panel 521 are all provided with a plurality of third light exit holes 5203 . The second connecting panel 524 is not provided with any third light exit holes 5203 .

[0083] The setting of the third light emitting hole 5203, on the one hand, further helps the disinfection lamp 3 to emit more light, further improving the sterilization effect; on the other hand, since the second lower side wall panel 522, the second right side wall panel 523 and the second upper side wall panel 521 are all arranged away from the first sub-cavity 51, although the second connecting wall panel 524 is close to the first sub-cavity 51, the third light emitting hole 5203 is not provided thereon, so that the light will not be irradiated to the first sub-cavity 51, thereby suppressing the influence of the disinfection lamp 3 on the fan 2 and the heating tube 6.

[0084] The present utility model also provides a cleaning machine, comprising an inner tank 1 and a protective cover 5.

[0085] like Figure 1 、 Figure 2 and Figure 6As shown, a protective cover 5 is provided on the rear wall plate 11 of the inner container 1, and a first sub-cavity 51 and a second sub-cavity 52 are arranged side by side on the left and right.

[0086] A water pipe 4 is vertically mounted on the rear wall 11, with a relief groove 54 positioned outside the pipe 4. A fan 2 and a disinfection lamp 3 are also mounted on the rear wall 11, positioned on either side of the water pipe 4. The fan 2 is located within the first sub-cavity 51, and the disinfection lamp 3 is located within the second sub-cavity 52. ​​This allows the fan 2 and disinfection lamp 3 to share a protective cover 5, eliminating the need for separate protective covers for the fan 2 and disinfection lamp 3, thereby improving the assembly efficiency of the cleaning machine.

[0087] A heating tube 6 is provided around the fan 2, and the heating tube 6 can heat the air and dry it with the hot air.

[0088] When the drying mode is on, the tableware is dried; when the disinfection mode is on, the tableware is disinfected. Under the dual effects of drying and disinfection, bacteria and viruses on the surface of the tableware are eliminated.

[0089] Of course, it is understandable that the drying mode can be turned on alone, or the disinfection mode can be turned on alone, or the drying mode and the disinfection mode can be turned on alternately.

[0090] In order to enable the water pipe 4 to be installed on the rear wall panel 11 of the inner tank 1, a recessed portion 53 and an avoidance groove 54 are provided on the protective cover 5, so that the water pipe 4 can pass through the avoidance groove 54 and the recessed portion 53, which helps the installation of the water pipe 4 and avoids the protective cover 5 affecting the installation of the water pipe 4.

[0091] In some embodiments, by limiting the size or shape of the recess 53, the side wall of the recess 53 can be brought into contact with the water pipe 4, which helps to limit the water pipe 4; of course, in some embodiments, a gap can be created between the side wall of the recess 53 and the water pipe 4, and the recess 53 is equivalent to protecting the water pipe 4.

[0092] It should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like used above to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0093] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also encompass other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.
