[0038] 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.

[0039] 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.

[0040] At least see Figures 1-6 As shown, the present invention provides a protective cover 5 , which includes a protective cover body 51 and a partition 52 .

[0041] The protective cover body 51 has a cavity 501. A sidewall of the cavity 501 is provided with an escape groove 502.

[0042] Among them, at least Figure 4 and Figure 5 As shown, the protective cover body 51 includes an end wall 511 and a side wall, and the side wall is arranged around the edge of the end wall 511 to form the above-mentioned cavity 501.

[0043] A partition 52 is disposed in the cavity 501 .

[0044] The separator 52 and the protective cover body 51 may be welded, threaded, pluggable, snap-fit, etc., and the embodiments are not listed here. The notch of the groove 5201 and the opening of the notch are arranged in the same direction and are flush with each other.

[0045] The partition 52 divides the cavity 501 into a first sub-cavity 5011 and a second sub-cavity 5012 which are arranged side by side and independent of each other.

[0046] Among them, such as Figure 1 and Figure 2 As shown, when the protective cover 5 is used in a washing machine, which can be a dishwasher, the first sub-cavity 5011 can be provided with the first fan 2 and the first heating tube 6, and the second sub-cavity 5012 can be provided with the second fan 3 and the second heating tube 7; of course, it is also possible to provide only the first fan 2 in the first sub-cavity 5011 and the second fan 3 and the second heating tube 7 in the second sub-cavity 5012; or, it is also possible to provide only the first fan 2 in the first sub-cavity 5011 and the second fan 3 and the second heating tube 7 in the second sub-cavity 5012; or, it is also possible to provide only the first fan 2 in the first sub-cavity 5011 and the second fan 3 and the second heating tube 7 in the second sub-cavity 5012; or, it is also possible to provide both the first fan 2 and the first heating tube 6 in the first sub-cavity 5011 and the second fan 3 in the second sub-cavity 5012.

[0047] In the following examples, a first fan 2 and a first heating tube 6 may be provided in the first sub-cavity 5011 , and a second fan 3 and a second heating tube 7 may be provided in the second sub-cavity 5012 .

[0048] Since the first sub-cavity 5011 and the second sub-cavity 5012 are independent of each other, the mutual influence between the first fan 2 and the first heating tube 6 and the second fan 3 and the second heating tube 7 can be suppressed.

[0049] In addition, the partition 52 is in contact with the end wall 511 or side wall of the cavity 501, and the partition 52 has abutting effect on the end wall 511 or side wall of the cavity 501, which can improve the overall strength and rigidity of the protective cover body 51, and avoid the deformation of the first sub-cavity 5011 and the second sub-cavity 5012 due to the deformation of the protective cover body 51, and the inability to install the protective cover 5 on the rear wall plate 11 of the cleaning machine, so as to respectively cover the first fan 2 and the first heating tube 6 in the first sub-cavity 5011, and cover the second fan 3 and the second heating tube 7 in the second sub-cavity 5012, or avoid the blades of the first fan 2 from scratching the cavity wall of the first sub-cavity 5011 when rotating, or avoid the blades of the second fan 3 from scratching the cavity wall of the second sub-cavity 5012 when rotating.

[0050] The separator 52 has a groove 5201 extending along the width of the protective cover body 51. The sidewall of the cavity 501 is provided with two opposing notches, the line connecting the two notches being in the same direction as the groove 5201. The two notches and the groove 5201 are connected to form a bypass groove 502 for the water supply pipe 4 to pass through.

[0051] 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 11 of the inner container 1. Since the protective cover body 51 is also located on the rear wall 11 of the inner container 1, in order to ensure that the installation of the protective cover body 51 and the water pipe 4 do not interfere with each other, the water pipe 4 passes through the groove 5201 and the avoidance groove 502, so that the water pipe 4 can supply water to the upper spray arm and other components, thereby achieving the installation of the protective cover 5 and the water pipe 4 without interfering with each other.

[0052] In addition, the partition 52 also protects the water pipe 4. The partition 52 can block the contact between hot air and the water pipe 4, inhibit the impact of hot air on the water pipe 4, and help to extend the service life of the water pipe 4.

[0053] In addition, in some embodiments, by limiting the size or shape of the avoidance groove 502, the groove wall of the avoidance groove 502 can be in contact with the water pipe 4, which helps to limit the water pipe 4 so that the water pipe 4 can be stably connected to the rear wall panel 11 of the inner tank 1.

[0054] The protective cover body 51 may be made of, but is not limited to, stainless steel.

[0055] The protective cover body 51 can be formed by, but is not limited to, sheet metal processing or stamping processing.

[0056] For example, the protective cover body 51 is formed using a stamping process. A stainless steel plate to be stamped is placed on a stamping device, and the punch presses the stainless steel plate, thereby forming the protective cover body 51 having a first sub-cavity 5011, a second sub-cavity 5012, and a relief groove 502. This allows the protective cover body 51 to be integrally formed, making processing simple and convenient, and helping to reduce production costs.

[0057] The separator 52 may be made of, but is not limited to, stainless steel.

[0058] The separator 52 can be formed by, but is not limited to, sheet metal processing or stamping processing.

[0059] As an implementation manner, in an orthographic projection of the groove 5201 on the sidewall of the cavity 501 provided with the notch, the projection area of ​​the groove 5201 covers the notch.

[0060] Specifically, at least Figure 3-Figure 5 In the example shown, the separator 52 is disposed in the middle of the cavity 501 in the left-right direction. The separator 52 can be elongated, extending in the vertical direction. The separator 52 includes a first connecting plate 521, a second connecting plate 522, and a third connecting plate 523. The first connecting plate 521 and the second connecting plate 522 are disposed opposite each other and located on the same side of the third connecting plate 523. Of course, it is understood that the separator 52 can also have other structures, which are not listed in this embodiment.

[0061] like Figure 4 As shown, the partition 52 divides the end wall 511 into two parts, wherein the area on the left side of the partition 52 is the first end wall 511a, and the area on the right side of the partition 52 is the second end wall 511b.

[0062] The side wall may include a left side wall 514 , a lower side wall 513 , a right side wall 515 and an upper side wall 512 that are sequentially connected end to end.

[0063] like Figure 4 and Figure 5 As shown, the left side wall 514 , the area of ​​the lower side wall 513 located on the left side of the partition 52 , the area of ​​the upper side wall 512 located on the left side of the partition 52 , the first connecting plate 521 and the first end wall 511 a constitute the first sub-cavity 5011 .

[0064] The right side wall 515 , the area of ​​the lower side wall 513 located on the right side of the partition 52 , the area of ​​the upper side wall 512 located on the right side of the partition 52 , the second connecting plate 522 and the second end wall 511 b form a second sub-cavity 5012 .

[0065] Notches are respectively provided on the upper side wall 512 and the lower side wall 513 . The groove 5201 of the separator 52 is orthographically projected on the upper side wall 512 or the lower side wall 513 , and the projection area of ​​the groove 5201 covers the notches.

[0066] like Figure 4 or Figure 5 As shown, the notch of the groove 5201 is larger than the opening of the notch.

[0067] The upper end of the partition 52 is seamlessly connected to the upper side wall 512, the lower end of the partition 52 is seamlessly connected to the lower side wall 513, and the third connecting plate 523 of the partition 52 is arranged parallel to the end wall 511 of the cavity 501, and the two are in seamless contact.

[0068] The first connecting plate 521 includes an end surface close to the opening of the cavity 501, and the end surface of the first connecting plate 521 is flush with the opening of the cavity 501; the second connecting plate 522 includes an end surface close to the opening of the cavity 501, and the end surface of the second connecting plate 522 is flush with the opening of the cavity 501[zhilin1].

[0069] As an implementation method, at least one of the first sub-cavity 5011 and the second sub-cavity 5012 is provided with an air inlet and an air outlet, and along the flow direction of the fluid, the air outlet is located downstream of the air inlet.

[0070] Specifically, at least Figure 3-Figure 5 In the example, a first air inlet area is provided on the first end wall 511a, and the first air inlet area is provided with a plurality of first air inlet holes 50111. The first air inlet area can be positioned directly opposite the first fan 2 to shorten the air inlet path, reduce air inlet resistance, and increase air intake volume. The plurality of first air inlet holes 50111 can be arranged in a circular array or a rectangular array.

[0071] like Figure 4 and Figure 5 As shown, first air outlets 50112 are provided on the left side wall 514 , the area of ​​the lower side wall 513 located on the left side of the partition 52 , and the area of ​​the upper side wall 512 located on the left side of the partition 52 .

[0072] like Figure 3 As shown, the first fan 2 rotates, causing air in the inner liner 1 to enter the first sub-cavity 5011 from the front of the first sub-cavity 5011 (or, the first air inlet 50111). The first heating tube 6 surrounding the first fan 2 heats the air, and the hot air is discharged into the inner liner 1 from the side of the first sub-cavity 5011 (or, the first air outlet 50112). This forms a first internal circulation air duct, preventing steam overflow.

[0073] Similarly, a second air inlet area is provided on the second end wall 511b, and is provided with a plurality of second air inlet holes 50121. The second air inlet area can be positioned directly opposite the second fan 3 to shorten the air inlet path, reduce air inlet resistance, and increase air intake. The plurality of second air inlet holes 50121 can be arranged in a circular array or a rectangular array.

[0074] like Figure 4 and Figure 5 As shown, fourth air outlets 50122 are provided on the right side wall 515 , the area of ​​the lower side wall 513 located on the right side of the partition 52 , and the area of ​​the upper side wall 512 located on the right side of the partition 52 .

[0075] like Figure 3As shown, the second fan 3 rotates, causing air in the inner liner 1 to enter the second sub-cavity 5012 from the front of the second sub-cavity 5012 (or, the second air inlet 50121). The second heating tube 7 surrounding the second fan 3 heats the air, and the hot air is discharged into the inner liner 1 from the side of the second sub-cavity 5012 (or, the fourth air outlet 50122). This forms a second internal circulation air duct, preventing steam overflow.

[0076] Furthermore, if Figure 4 and Figure 5 As shown, the first air inlet area is offset on the first end wall 511a in a direction away from the second sub-cavity 5012, or / and the second air inlet area is offset on the second end wall 511b in a direction away from the first sub-cavity 5011. This helps the first internal circulation air duct to deviate to the left; helps the second internal circulation air duct to deviate to the right, further suppressing the mutual influence between the first and second internal circulation air ducts.

[0077] Furthermore, if Figure 4 and Figure 5 As shown, the total area of ​​the first air inlet hole 50111 is equal to the total area of ​​the second air inlet hole 50121; the arrangement of the first air inlet hole 50111 and the arrangement direction of the second air inlet hole 50121 are the same; the first air inlet hole 50111 and the second air inlet hole 50121 are spaced apart along the length direction of the protective cover body 51.

[0078] The total area of ​​the first air outlet 50112 is equal to the total area of ​​the fourth air outlet 50122. The first air outlet 50112 and the fourth air outlet 50122 are spaced apart along the length direction of the protective cover body 51 and can be symmetrically arranged about the partition 52.

[0079] In this way, the overall structure of the protective cover body 51 can be kept consistent, thereby improving the overall aesthetics of the protective cover body 51.

[0080] Furthermore, a plurality of second air outlet holes 50113 are provided on the first end wall 511a at least near the partition 52, and the second air outlet holes 50113 are arranged along the width direction of the protective cover body 51, and a plurality of fifth air outlet holes 50123 are provided on the second end wall 511b at least near the partition 52, and the fifth air outlet holes 50123 are arranged along the width direction of the protective cover body 51.

[0081] like Figure 5 and Figure 6 As shown, a plurality of second air outlet holes 50113 are provided in the area of ​​the first end wall 511a close to the third connecting plate 523. The plurality of second air outlet holes 50113 are arranged in the up and down directions, and the plurality of second air outlet holes 50113 can be arranged at equal intervals.

[0082] A plurality of fifth air outlet holes 50123 are provided in an area of ​​the second end wall 511b close to the third connecting plate 523. The plurality of fifth air outlet holes 50123 are arranged in the up-down direction and may be arranged at equal intervals.

[0083] like Figure 3 As shown, since the hot air discharged through the second air outlet 50113 and the fifth air outlet 50123 moves forward, and the second air outlet 50113 and the fifth air outlet 50123 are separated by the third connecting plate 523, it helps to suppress the mutual influence between the first internal circulation air duct and the second internal circulation air duct.

[0084] Among them, such as Figure 4 and Figure 5 As shown, the arrangement of the second air outlet holes 50113 and the arrangement of the fifth air outlet holes 50123 can be the same, and the second air outlet holes 50113 and the fifth air outlet holes 50123 can be symmetrically arranged about the partition 52.

[0085] Furthermore, in some embodiments, the angle between the first end wall 511a and the first connecting plate 521 is α, and α is an acute angle, such as Figure 3 As shown, this helps the hot air to be quickly discharged from the second air outlet 50113; similarly, the angle between the second end wall 511b and the second connecting plate 522 is α, α is an acute angle, such as Figure 3 As shown, this helps the hot air to be discharged quickly from the fifth air outlet 50123.

[0086] Furthermore, a plurality of third air outlet holes 50114 are provided on the first end wall 511a on the side of the first air inlet area away from the partition 52, and the third air outlet holes 50114 are close to the corner of the first end wall 511a, and a plurality of sixth air outlet holes 50124 are provided on the second end wall 511b on the side of the second air inlet area away from the partition 52, and the sixth air outlet holes 50124 are close to the corner of the second end wall 511b.

[0087] like Figure 4 and Figure 5 As shown, since the third air outlet 50114 is arranged away from the second sub-cavity 5012 and the sixth air outlet 50124 is arranged away from the first sub-cavity 5011, it helps to suppress the mutual influence between the first internal circulation air duct and the second internal circulation air duct.

[0088] Among them, such as Figure 4 and Figure 5 As shown, the arrangement of the third air outlet holes 50114 and the arrangement of the sixth air outlet holes 50124 can be the same, and the third air outlet holes 50114 and the sixth air outlet holes 50124 can be symmetrically arranged with respect to the partition 52 .

[0089] As a feasible method, the total area of ​​the third air outlet 50114, the second air outlet 50113, and the first air outlet 50112 is less than or equal to the total area of ​​the first air inlet 50111. This can make the hot air discharged from the air outlet have a higher wind pressure and a faster flow rate, so that the hot air can flow more fully in the inner liner 1.

[0090] As a feasible method, the total area of ​​the sixth air outlet 50124, the fifth air outlet 50123, and the fourth air outlet 50122 is less than or equal to the total area of ​​the second air inlet 50121. This can make the hot air discharged from the air outlet have a higher wind pressure and a faster flow rate, so that the hot air can flow more fully in the inner liner 1.

[0091] The present utility model also provides a cleaning machine, comprising an inner tank 1 and a protective cover 5.

[0092] like Figure 1 、 Figure 2 and Figure 3 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.

[0093] A water pipe 4 is vertically mounted on the rear wall 11. The water pipe 4 passes through the groove 5201 and the avoidance slot 502, allowing the protective cover 5 and the water pipe 4 to be installed independently of each other. Furthermore, the separator 52 also protects the water pipe 4 by preventing hot air from coming into contact with it, thus reducing its impact and extending its service life.

[0094] In addition, in some embodiments, by limiting the size or shape of the avoidance groove 502, the groove wall of the avoidance groove 502 can be in contact with the water pipe 4, which helps to limit the water pipe 4 so that the water pipe 4 can be stably connected to the rear wall panel 11 of the inner tank 1.

[0095] The rear wall panel 11 is also equipped with a first fan 2, a second fan 3, a first heating tube 6, and a second heating tube 7. The first fan 2, first heating tube 6, second fan 3, and second heating tube 7 are located on either side of the water tube 4. The first fan 2 and first heating tube 6 are located in the first sub-cavity 5011, with the first heating tube 6 surrounding the first fan 2. The second fan 3 and second heating tube 7 are located in the second sub-cavity 5012, with the second heating tube 7 surrounding the second fan 3. This allows the first fan 2, first heating tube 6, second fan 3, and second heating tube 7 to share a single protective cover 5, eliminating the need to install separate protective covers for the first fan 2, first heating tube 6, second fan 3, and second heating tube 7, thereby improving the assembly efficiency of the cleaning machine.

[0096] The first sub-cavity 5011 is provided with air inlet and outlet holes to form a first internal circulation air duct. The second sub-cavity 5012 is provided with air inlet and outlet holes to form a second internal circulation air duct. Since the first sub-cavity 5011 and the second sub-cavity 5012 are independent of each other, it helps to prevent mutual interference between the second internal circulation path and the first internal circulation path.

[0097] When the drying function of the washing machine is turned on, the two drying modules can run together, which can quickly raise the temperature in the inner tank 1 to a higher temperature to meet the user's needs for rapid sterilization. You can also set the left or right drying module to run according to the specific position of the tableware on the shelf, and only run one of the drying modules to perform independent drying and sterilization more accurately. For energy-saving washing modes with relatively high energy consumption requirements, you can only turn on the first fan 2 or the third fan 2, and do not turn on the first heating tube 6 and the second heating tube 7, to speed up the air flow in the inner tank 1, thereby improving the drying effect.
