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] After drying dishes, some water remains in the washing machine's cavity, which can easily breed bacteria and create odors. A poor external environment can also further deteriorate the air quality within the cavity. To ensure clean air within the washing machine and prevent the growth of odors and bacteria, sterilization devices are used. Currently, most sterilization methods use silver ion sterilization, electric heating, or ultraviolet light.

[0004] In the related art, the sterilization device includes a sterilization lamp and a protective cover covering the sterilization lamp. In order to allow the light of the sterilization lamp to enter the inner tank of the washing machine, a light outlet hole is opened on the protective cover, so that the light emitted by the sterilization lamp passes through the light outlet hole to sterilize the tableware.

[0005] However, the arrangement of existing light exit holes affects the sterilization effect. Utility Model Content

[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 Figures 1-6 As shown, the example of the present invention provides a protective cover 5, comprising: a protective cover body, the protective cover body is provided with a first sub-cavity 51 and a second sub-cavity 52 which are arranged side by side and independent of each other.

[0038] Among them, at least Figure 3 and Figure 4 As shown, the protective cover body includes a side wall and an end wall, and the side wall is arranged around the edge of the end wall to form a cavity 501.

[0039] The side wall is provided with an escape groove 54. A recessed portion 53 is provided in the middle of the end wall, which is recessed to the bottom of the escape groove 54. The recessed portion 53 divides the cavity 501 into a first sub-cavity 51 and a second sub-cavity 52, which are arranged side by side and are independent of each other.

[0040] Among them, at least Figure 4 As shown, the edge of the side wall at the opening of the cavity 501 is recessed from rear to front to form an avoidance groove 54. The middle part of the end wall is recessed from front to rear to form a recessed portion 53.

[0041] In detail: Figure 4 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 recessed portion 53 may have other structures, which are not listed in this embodiment.

[0042] The long groove divides the end wall into two parts, wherein the area on the right side of the long groove is the first end wall 515 , and the area on the left side of the long groove is the second end wall 525 .

[0043] The sidewalls include a first left sidewall 514 , a first lower sidewall 512 , a first right sidewall 513 , a first upper sidewall 511 , a second left sidewall 524 , a second lower sidewall 522 , a second right sidewall 523 and a second upper sidewall 521 .

[0044] The first left side wall 514, the first lower side wall 512, the first right side wall 513, and the first upper side wall 511 are connected end to end and arranged around the edge of the first end wall 515, thereby forming the first sub-cavity 51. It should be noted that the first sub-cavity 51 and the recessed portion 53 share the first left side wall 514.

[0045] The second left side wall 524, the second lower side wall 522, the second right side wall 523, and the second upper side wall 521 are connected end to end and arranged around the edge of the second end wall 525 to form the second sub-cavity 52. ​​It should be noted that the second sub-cavity 52 and the recessed portion 53 share the second right side wall 523.

[0046] The protective cover 5 is used in a cleaning machine, which may be a dishwasher. A hot air device may be provided in the first sub-cavity 51. Generally, the hot air device may include a fan 2 and a heating pipe 6. The second sub-cavity 52 may be provided with a disinfection lamp 3. Alternatively, the disinfection lamp 3 may be provided in the first sub-cavity 51, and the fan 2 and heating pipe 6 may be provided in the second sub-cavity 52.

[0047] The following examples are described by taking the case where the disinfection lamp 3 is arranged in the first sub-cavity 51 and the fan 2 and the heating tube 6 are arranged in the second sub-cavity 52 as an example.

[0048] Since the first sub-cavity 51 and the second sub-cavity 52 are independent of each other, the mutual influence among the fan 2 , the heating tube 6 and the disinfection lamp 3 can be suppressed.

[0049] 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 11 of the cleaning machine; or preventing the first sub-cavity 51 from being deformed and contacting the disinfection lamp 3 installed therein, causing damage to the disinfection lamp 3; or preventing the blades of the fan 2 from scratching the cavity wall of the second sub-cavity 52 during rotation.

[0050] The protective cover body can be made of, but is not limited to, stainless steel.

[0051] The protective cover body can be made of, but is not limited to, sheet metal processing or stamping processing.

[0052] 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.

[0053] 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. By providing the avoidance groove 54, the water pipe 4 can pass through the avoidance groove 54 through the protective cover 5, so that the water pipe 4 can supply water to the upper spray arm and other components, so that the installation of the protective cover 5 and the water pipe 4 does not affect each other.

[0054] A plurality of light exit holes are provided on the end wall of the first sub-cavity 51 , and at least some of the light exit holes are arranged radially.

[0055] like Figure 3 As shown, a first light exit hole 5101 and a plurality of second light exit holes 5102 are provided on the first end wall 515. The first light exit hole 5101 and the second light exit holes 5102 all pass through the first end wall 515.

[0056] like Figure 3 As shown, the first light exit hole 5101 extends left and right along a straight line and can be in the shape of an elliptical strip, a rectangular strip, a diamond strip, etc. The extension direction of the first light exit hole 5101 is the same as the length direction of the protective cover body, and the first light exit hole 5101 passes through the cavity end wall of the first sub-cavity 51.

[0057] At least Figure 2 and Figure 5 As shown, the disinfection lamp 3 is positioned corresponding to the first light exit hole 5101. The disinfection lamp 3 can be, but is not limited to, a long, strip-shaped UV lamp tube. The length of the disinfection lamp 3 is arranged in the left-right direction. The disinfection lamp 3 includes a first mounting end 31, a second mounting end 32, and an irradiation section 33 located between the first and second mounting ends 31, 32. The length of the irradiation section 33 is greater than or equal to the length of the first light exit hole 5101.

[0058] Because the first light exit holes 5101 are arranged corresponding to the disinfection lamp 3 and have a larger area, more light can be irradiated directly in front of the first sub-cavity 51, which helps to improve the sterilization effect. The radially arranged second light exit holes 5102 allow more light to be irradiated in front of the first sub-cavity 51, expanding the light coverage area and further improving the sterilization effect.

[0059] As an implementable manner, first profiles 5104 are respectively provided on part of the end walls of the first sub-cavity 51 corresponding to both ends of the first light exit hole 5101 , and the first profiles 5104 are at least located on the light propagation path beside the first light exit hole 5101 .

[0060] At least Figure 2 and Figure 5 As shown, a plurality of first profiles 5104 are provided on the left side of the first light exit hole 5101. The first profiles 5104 correspond to the first mounting end 31 and at least block the first mounting end 31. Another plurality of first profiles 5104 are provided on the right side of the first light exit hole 5101. The first profiles 5104 correspond to the second mounting end 32 and at least block the second mounting end 32. Figure 3 As shown, three first profiles 5104 are provided corresponding to each mounting end. The provision of the first profiles 5104 not only increases the rigidity of the first end wall 515 but also shields the first mounting end 31 and the second mounting end 32 from light, making them invisible from the inner liner 1. This helps enhance the aesthetics of the inner liner 1 and improves the user experience. Furthermore, the first profiles 5104 prevent water from entering the first mounting end 31 and the second mounting end 32, thereby preventing short circuits in the disinfection lamp 3.

[0061] Among them, Figure 3 and Figure 4 As shown, a portion of the first end wall 515 is provided with an arcuate groove that is recessed from front to back (or toward the interior of the first sub-cavity 51), and this arcuate groove is the first press profile 5104. Alternatively, a portion of the first end wall 515 is provided with an arcuate protrusion that is convex from back to front, and this arcuate protrusion is the first press profile 5104.

[0062] It should be noted that when the protective cover body is formed by a stamping process, the first pressing profile 5104 can be formed by stamping.

[0063] Several second light exit holes 5102 are located between the two left and right first press profiles 5104, and a portion of the several second light exit holes 5102 are located on the upper side of the first light exit hole 5101, and the remaining portion of the several second light exit holes 5102 are located on the lower side of the first light exit hole 5101.

[0064] The first press profile 5104 and the second light exit hole 5102 can be set to have the same shape (it can simply mean that the structure is the same, both are arc-shaped, but the size is different; it can also mean that the structure and size are the same), and the second light exit hole 5102 on the upper side, the second light exit hole 5102 on the lower side, the first press profile 5104 on the left side, and the first press profile 5104 on the right side are arranged in a radial shape with respect to the first light exit hole 5101, which can further enhance the aesthetics of the protective cover body.

[0065] Among them, Figure 3 As shown, the arc-shaped second light exit hole 5102 includes a first end and a second end, the first end is arranged close to the first light exit hole 5101, and the second end is arranged away from the first light exit hole 5101.

[0066] Multiple second light exit holes 5102 form a light exit hole group. The second light exit holes 5102 in each light exit hole group are arranged side by side and concentrically. The second light exit holes 5102 in each light exit hole group extend in different directions. This helps to allow more light to reach the front of the first sub-cavity 51, expand the light coverage area, and further improve the sterilization effect.

[0067] like Figure 3 As shown, a plurality of light exit holes form a light exit unit. The light exit unit and the first press profile 5104 are arranged around the first light exit hole 5101, and the light exit unit and the first press profile 5104 are arranged alternately.

[0068] As an achievable method, Figure 3 and Figure 4 As shown, at least one circle of second profile 5105 is provided on the end wall of the first sub-cavity 51. The first profile 5104, the first light exit hole 5101 and the second light exit hole 5102 are all located within the range surrounded by the second profile 5105.

[0069] Part of the first end wall 515 is recessed with at least one annular groove from front to back (or toward the interior of the first sub-cavity 51), and the first protrusion 5104, the first light exit hole 5101, and the second light exit hole 5102 are all located within the range enclosed by the annular groove. This annular groove is the second protrusion 5105. Alternatively, part of the first end wall 515 is convexed with at least one annular protrusion from back to front, and the first protrusion 5104, the first light exit hole 5101, and the second light exit hole 5102 are all located within the range enclosed by the annular protrusion. This annular protrusion is the second protrusion 5105.

[0070] It should be noted that when the protective cover body is formed by a stamping process, the second pressing profile 5105 can be formed by stamping.

[0071] The setting of the second press profile 5105 can improve the rigidity and strength of the end wall of the first sub-cavity 51, help the end wall of the first sub-cavity 51 to ensure its flatness, and reduce the probability of damage to the disinfection lamp 3 due to deformation of the end wall of the first sub-cavity 51.

[0072] As an achievable method, at least Figure 3 and Figure 4 As shown, the first lower sidewall 512, the first right sidewall 513, and the first upper sidewall 511 are all disposed away from the second sub-cavity 52, and a plurality of third light exit holes 5103 are defined on each of the first lower sidewall 512, the first right sidewall 513, and the first upper sidewall 511. The first left sidewall 514 is disposed proximate to the second sub-cavity 52, and does not define the third light exit holes 5103.

[0073] The setting of the third light emitting hole 5103, on the one hand, further helps the light of the disinfection lamp 3 to emit more light out of the first sub-cavity 51, further improving the sterilization effect; on the other hand, since the first lower side wall 512, the first right side wall 513 and the first upper side wall 511 are all set away from the second sub-cavity 52, the light will not directly irradiate the second sub-cavity 52, thereby suppressing the adverse effects of the disinfection lamp 3 on the fan 2 and the heating tube 6.

[0074] As an achievable method, Figure 3 As shown, an air inlet area 5204 is provided on the second end wall 525. The air inlet area 5204 is provided with a plurality of air inlet holes 5201. The air inlet area 5204 can be arranged directly opposite the fan 2 to shorten the air inlet path, reduce the air inlet resistance, and increase the air inlet volume. The plurality of air inlet holes 5201 can be arranged radially, or in a circular array or in a rectangular array. Figure 3 As shown, it can be considered that the multiple air inlet holes 5201 are arranged radially.

[0075] The second left sidewall 524, the second lower sidewall 522, and the second upper sidewall 521 are all located away from the first sub-cavity 51. A plurality of air outlet holes 5202 are provided on each of the second left sidewall 524, the second lower sidewall 522, and the second upper sidewall 521. The plurality of air outlet holes 5202 can be arranged in a circular array or a rectangular array. The second right sidewall 523 is located closer to the first sub-cavity 51 and does not have any air outlet holes 5202.

[0076] Since the second left side wall 524 , the second lower side wall 522 and the second upper side wall 521 are all arranged away from the first sub-cavity 51 , the air outlets 5202 are not oriented toward the first sub-cavity 51 , thereby suppressing the influence of the fan 2 on the disinfection lamp 3 .

[0077] Furthermore, if Figure 3 As shown, the air inlet area 5204 is offset on the second end wall 525 in a direction away from the first sub-cavity 51. In this way, each air outlet 5202 is further away from the first sub-cavity 51, further suppressing the influence of the fan 2 on the disinfection lamp 3.

[0078] As an implementable manner, at least one circle of third profile 5203 is provided on the end wall of the second sub-cavity 52 around the air inlet area 5204 .

[0079] It should be noted that the structure of the third press profile 5203 is the same as that of the first press profile 5104 and the second press profile 5105. Please refer to the above description and it will not be repeated here.

[0080] like Figure 3-Figure 5As shown, the second end wall 525 is provided with at least one annular groove extending from front to back, which is a third profile 5203. The third profile 5203 surrounds the air inlet area 5204. The third profile 5203 enhances the rigidity and strength of the second end wall 525, ensuring its flatness and reducing the probability of the blades of the fan 22 rubbing against it due to deformation of the second end wall 525.

[0081] Furthermore, if Figure 4-6 As shown, the air inlet area 5204 of the second end wall 525 protrudes from the back to the front by a distance d2, as shown in FIG. Figure 6 As shown, the air inlet area 5204 of the second end wall 525 and the area of ​​the second end wall 525 except the air inlet area 5204 are not on the same plane, which increases the distance between the air inlet area 5204 and the blades of the fan 2, and reduces the probability that the second end wall 525 is deformed and causes the blades of the fan 2 to scratch the second end wall 525.

[0082] The present utility model also provides a cleaning machine, comprising an inner tank 1 and a protective cover 5.

[0083] like Figure 1 、 Figure 2 and Figure 5 As 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.

[0084] A water pipe 4 is vertically arranged on the rear wall plate 11 , and the avoidance groove 54 is stuck outside the water pipe 4 . A hot air device is also arranged on the rear wall plate 11 , and the hot air device includes a fan 2 and a heating pipe 6 .

[0085] The fan 2, heating tube 6, and disinfection lamp 3 are placed on either side of the water pipe 4. The disinfection lamp 3 is located in the first sub-cavity 51, and the fan 2 is located in the second sub-cavity 52. ​​This allows the fan 2 and disinfection lamp 3 to share a protective cover 5, eliminating the need to install separate protective covers 5 for the fan 2 and disinfection lamp 3, thereby improving the assembly efficiency of the cleaning machine.

[0086] like Figure 5 As shown, there is a gap between the disinfection lamp 3 and the end wall of the first sub-cavity 51. Specifically, as shown in the figure, a gap d1 exists between the first end wall 515 and the disinfection lamp 3 in the front-to-back direction, with a range of 5mm≤d1≤15mm. This gap prevents damage to the disinfection lamp 3 caused by deformation of the first end wall 515 and contact with it, while also preventing an excessively large gap that would cause the protective cover 5 to excessively encroach on the space within the inner container 1 where tableware is placed.

[0087] The hot air device includes a fan 2 and a heating pipe 6 surrounding the fan 2, and the heating pipe 6 can heat the air, thereby drying and disinfecting the air. The disinfection lamp 3 can be a UV lamp or a UV LED.

[0088] Because the cleaning machine is equipped with a hot air device and a disinfection lamp, it can have multiple operating modes, such as drying mode and disinfection mode. When the drying mode is activated, the tableware is dried by hot air; when the disinfection mode is activated, the tableware is disinfected. Disinfection modes include hot air disinfection, UV lamp disinfection, and a combination of hot air and UV lamp disinfection. The combination of hot air and UV lamp disinfection maximizes the disinfection capacity of the cleaning machine, enabling it to achieve the two-star disinfection capability of a disinfection cabinet.
