[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 present invention provides a protective cover 5 , which includes a protective cover body 51 and a partition 52 .
[0038] The protective cover body 51 includes a cavity 501. The protective cover body 51 forms an opening of the cavity 501 on a first side, and forms an end wall plate 511 of the cavity 501 on a second side. The first side and the second side are arranged opposite to each other.
[0039] The end wall 511 of the protective cover body 51 is provided with a plurality of side panels around its periphery, and the plurality of side panels are provided around the edge of the end wall 511 to form the aforementioned cavity 501 .
[0040] The protective cover body 51 may be made of, but is not limited to, stainless steel.
[0041] The protective cover body 51 can be made of, but is not limited to, a sheet metal process or a stamping process.
[0042] For example, Figure 3-Figure 5 As shown, the protective cover body 51 is formed by a stamping process. A stainless steel plate to be stamped is placed on a stamping device, and a stamping head stamps the stainless steel plate to form the protective cover body 51 having a cavity 501.
[0043] like Figure 4 As shown, the partition 52 is connected to the protective cover body 51 and is at least partially located in the cavity 501, for dividing the cavity 501 into a first sub-cavity 5011 and a second sub-cavity 5012 arranged side by side.
[0044] The separator 52 may be made of, but is not limited to, stainless steel.
[0045] The separator 52 and the protective cover body 51 can be welded, threaded, plugged, snap-fitted, etc., and are not listed one by one in this embodiment.
[0046] The partition 52 is arranged close to the opening of the cavity 501 so as to leave a gap between it and the end wall plate 511 of the cavity 501 to form an air duct, which connects the first sub-cavity 5011 and the second sub-cavity 5012 .
[0047] In one embodiment, Figure 3 and Figure 4 As shown, the divider 52 is disposed within the cavity 501, and a gap exists between the divider 52 and the end wall 511 of the protective cover body 51, which can serve as an air duct. In another embodiment, the divider 52 is disposed within the cavity 501, and a gap exists between the divider 52 and the side panels of the protective cover body 51, which can serve as an air duct. In yet another embodiment, the divider 52 is disposed within the cavity 501, and no gap exists between the divider 52 and the end wall 511 and side panels of the protective cover body 51, and the divider 52 is provided with a through hole, which can serve as an air duct.
[0048] like Figure 3 As shown, since the first sub-cavity 5011 and the second sub-cavity 5012 are connected through the air duct, the air in the first sub-cavity 5011 flows to the second sub-cavity 5012 through the air duct, or the air in the second sub-cavity 5012 flows to the first sub-cavity 5011 through the air duct.
[0049] When the protective cover is used in a washing machine, which may be a dishwasher, the first sub-cavity 5011 may be provided with a fan 2 and a heating tube 3, while the second sub-cavity 5012 may not be provided with the fan 2 and the heating tube 3. Alternatively, the second sub-cavity 5012 may be provided with a fan 2 and a heating tube 3, while the first sub-cavity 5011 may not be provided with the fan 2 and the heating tube 3. Alternatively, the second sub-cavity 5012 may be provided with only a fan 2, while the first sub-cavity 5011 may not be provided with the fan 2 and the heating tube 3. Alternatively, the first sub-cavity 5011 may be provided with only a fan 2, while the second sub-cavity 5012 may not be provided with the fan 2 and the heating tube 3.
[0050] The following examples are described by taking the example that the fan 2 and the heating tube 3 can be set in the first sub-cavity 5011, and the fan 2 and the heating tube 3 are not set in the second sub-cavity 5012.
[0051] like Figure 1-Figure 3 As shown, in actual application, the protective cover is installed on the rear wall plate 11 of the inner liner 1. In order to evenly distribute the hot air in the inner liner 1, at least an air inlet hole can be provided on the wall of the first sub-cavity 5011, and at least an air outlet hole can be provided on the wall of the second sub-cavity 5012. Figure 3 As shown, the air outlet can be located in the left area of the inner liner 1, and the air inlet can be located in the right area of the inner liner 1.
[0052] When fan 2 is activated, air in inner liner 1 enters first sub-cavity 5011 through the air inlet. Simultaneously, this air is heated by heating tube 3 to form hot air. The hot air in first sub-cavity 5011 flows through the air duct to second sub-cavity 5012, and is then discharged into inner liner 1 through the air outlet. This hot air gradually diffuses from the left side of inner liner 1 to the right side, distributing it evenly throughout the inner liner 1 and improving drying efficiency.
[0053] In addition, the fan 2 is only provided in the first sub-cavity 5011 , which avoids providing fans 2 in two sub-cavities at the same time, reduces the number of fans 2 , and thus reduces production costs.
[0054] As an implementable manner, the end wall plate 511 is a long strip end wall plate 511 , and the partition 52 is used to divide the cavity 501 into a first sub-cavity 5011 and a second sub-cavity 5012 arranged side by side along the length direction of the long strip end wall plate 511 .
[0055] Specifically, at least Figure 3 and Figure 4 In the example of FIG, the protective cover body 51 includes an end wall plate 511 and four side plates. The end wall plate 511 is a long strip end wall plate 511, and the length of the long strip end wall plate 511 extends in the left-right direction.
[0056] The four side panels may include a left side panel 515, a right side panel 514, an upper side panel 512 and a lower side panel 513. The left side panel 515, the lower side panel 513, the right side panel 514 and the upper side panel 512 are connected end to end in sequence and surround the edge of the end wall panel 511 to form a cavity 501.
[0057] like Figure 6As shown, the separator 52 is elongated and can be formed using, but is not limited to, sheet metal or stamping processes. 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. It is understood that the separator 52 can also have other structures, which are not listed in this embodiment.
[0058] like Figure 4 As shown, the partition 52 can be located in the middle position in the left-right direction of the cavity 501, and the length of the partition 52 extends along the up-down direction of the cavity 501 until the upper end of the partition 52 is seamlessly connected to the upper side plate 512; the lower end of the partition 52 is seamlessly connected to the lower side plate 513, and the third connecting plate 523 of the partition 52 is parallel to the end wall plate 511 and is spaced apart, so that the above-mentioned air duct is formed between the partition 52 and the protective cover body 51.
[0059] like Figure 6 As shown, the area of the end wall plate 511 located on the right side of the partition 52 is the first right side portion 5111, that is, the first right side portion 5111 is the position on the end wall plate 511 corresponding to the first sub-cavity 5011; the area of the end wall plate 511 located on the left side of the partition 52 is the first left side portion 5112, that is, the first left side portion 5112 is the position on the end wall plate 511 corresponding to the second sub-cavity 5012.
[0060] like Figure 4 and Figure 5 As shown, the area of the upper side plate 512 located on the right side of the partition 52 is the first upper right side portion 5121 ; the area of the upper side plate 512 located on the left side of the partition 52 is the first upper left side portion 5122 .
[0061] like Figure 4 and Figure 5 As shown, the area of the lower side plate 513 located on the right side of the partition 52 is the first lower right side portion 5131 ; the area of the lower side plate 513 located on the left side of the partition 52 is the first lower left side portion 5132 .
[0062] The first right side portion 5111 , the first upper right side portion 5121 , the first lower right side portion 5131 , the right side plate 514 and the first connecting plate 521 constitute the aforementioned first sub-cavity 5011 .
[0063] The first left side portion 5112 , the first upper left side portion 5122 , the first lower left side portion 5132 , the left side plate 515 and the second connecting plate 522 constitute the aforementioned second sub-cavity 5012 .
[0064] like Figure 4As shown, the second sub-cavity 5012 and the first sub-cavity 5011 are arranged side by side in the left-right direction, and the direction of the parallel arrangement is perpendicular to the length extension direction of the partition 52. Of course, it can be understood that in some embodiments, the direction of the parallel arrangement intersects with the length extension direction of the partition 52, but is not perpendicular.
[0065] The long strip end wall plate 511 helps to extend the path of the hot air in the first sub-cavity 5011 to the second sub-cavity 5012 through the air duct. Correspondingly, after the hot air enters the inner tank 1, the path of the hot air moving from the left area to the right area in the inner tank 1 is extended, which extends the contact time between the hot air and the tableware and helps to improve the drying effect.
[0066] The partition 52 includes a groove 5201 that is recessed from the opening toward the end wall plate 511 , and the length extension direction of the groove 5201 intersects with the length direction of the long strip end wall plate 511 .
[0067] like Figure 6 As shown, the angle between the first connecting plate 521 and the third connecting plate 523 can be an acute angle, and the angle between the second connecting plate 522 and the third connecting plate 523 can be an acute angle, and the two acute angles can be equal. Thus, the separator 52 composed of the first connecting plate 521, the second connecting plate 522, and the third connecting plate 523 has a groove 5201. The groove 5201 is an elongated groove, and the length of the elongated groove extends in the vertical direction.
[0068] 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 vertically and 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, to ensure that the protective cover body 51 and the water pipe 4 do not interfere with each other, notches 5105 are respectively provided on the upper side plate 512 and the lower side plate 513. The two notches 5105 are arranged opposite each other, and the direction of the line connecting the two notches 5105 is the same as the length of the groove 5201. The two notches 5105 and the groove 5201 are connected to form an escape groove for the water pipe 4 to pass through.
[0069] In this way, the installation of the protective cover 5 and the water pipe 4 can be achieved without affecting each other. In addition, the separator 52 also protects the water pipe 4. The separator 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 extend the service life of the water pipe 4.
[0070] The end wall plate 511 and the side plates are respectively provided with a plurality of ventilation holes.
[0071] Specifically, at least Figure 4 and Figure 5 In the example, the ventilation hole includes a first air inlet hole 5101 and a first air outlet hole 5102 , and along the flow direction of the fluid, the first air outlet hole 5102 is located downstream of the first air inlet hole 5101 .
[0072] Because the first sub-cavity 5011 is provided with the fan 2 and the heating tube 3, an air inlet area is correspondingly provided on the first right side portion 5111, and a plurality of first air inlet holes 5101 are disposed in the air inlet area. The air inlet area 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 first air inlet holes 5101 can be arranged in a rectangular array or a circular array. The shapes and sizes of the first air inlet holes 5101 may be the same or different.
[0073] An air outlet area is provided on the second left side portion 5112, and a plurality of first air outlet holes 5102 are provided in the air outlet area. The plurality of first air outlet holes 5102 can be arranged in a rectangular array or a circular array. The shapes and sizes of the first air outlet holes 5102 can be the same or different.
[0074] like Figure 3 As shown, the hot air discharged through the first air outlet 5102 can move along the front of the inner liner 1, which helps the hot air enter the left area of the inner liner 1 and prevents the hot air from contacting the cavity wall of the inner liner 1. The hot air gradually diffuses from the left area to the right area of the inner liner 1, which helps the hot air be evenly distributed in the inner liner 1.
[0075] Furthermore, the ventilation holes further include second air outlet holes 5103. A plurality of second air outlet holes 5103 are provided at the four corners of the end wall plate 511.
[0076] like Figure 4 and Figure 5 As shown, the second air outlet 5103 may be located at the upper left corner or the lower left corner of the first left side portion 5112. The second air outlet 5103 may have the same or different shapes and sizes.
[0077] The second air outlet 5103 allows more hot air to be discharged through the second air outlet 5103. Since the second air outlet 5103 is located away from the first sub-cavity 5011, the hot air can gradually diffuse from the left area to the right area of the inner liner 1, further helping to evenly distribute more hot air in the inner liner 1.
[0078] Furthermore, the ventilation holes include the first air outlet hole 5102 and the second air outlet hole 5103 , and further include the second air outlet hole 5103 .
[0079] like Figure 4 and Figure 5As shown, a plurality of third air outlet holes 5104 are provided on the first upper left portion 5122, the first lower left portion 5132, and the left side plate 515. The plurality of third air outlet holes 5104 can be arranged in a rectangular array or a circular array. The shapes and sizes of the third air outlet holes 5104 can be the same or different.
[0080] The third air outlet 5104 allows more hot air to be discharged through the third air outlet 5104. Since the first upper left portion 5122, the first lower left portion 5132, and the left plate 515 are all located away from the first sub-cavity 5011, the hot air can gradually diffuse from the left area to the right area of the inner liner 1, further helping to evenly distribute more hot air in the inner liner 1.
[0081] Furthermore, in order to maintain the overall consistency of the protective cover body 51, the overall aesthetics of the protective cover body 51 is enhanced.
[0082] like Figure 4 and Figure 5 As shown, the second air outlet 5103 can be located at the upper right corner or the lower right corner of the first right side portion 5111. The arrangement of the plurality of second air outlet holes 5103 on the first right side portion 5111 is the same as the arrangement of the plurality of second air outlet holes 5103 on the first left side portion 5112, and the two are symmetrically arranged about the partition 52.
[0083] Similarly, if Figure 4 and Figure 5 As shown, a plurality of third air outlet holes 5104 are provided on the first upper right side portion 5121, the first lower right side portion 5131 and the right side plate 514. The arrangement of the plurality of third air outlet holes 5104 on the first upper right side portion 5121, the first lower right side portion 5131 and the right side plate 514 is the same as the arrangement of the plurality of third air outlet holes 5104 on the first upper left side portion 5122, the first lower left side portion 5132 and the left side plate 515, and the two are arranged symmetrically about the partition 52.
[0084] Furthermore, a closed area is provided on the end wall plate 511 between the air inlet area and the air outlet area, and no ventilation holes are provided in the closed area.
[0085] like Figure 3-Figure 5 As shown, the partition 52 is located between the air inlet area and the air outlet area of the protective cover body 51, and the area between the partition 52 and the air inlet area and the air outlet area of the protective cover body 51 forms the above-mentioned air duct. The air duct is set as a closed area, which means that no air outlet holes are set on the partition 52, and no air outlet holes are set in the area between the air inlet area and the air outlet area of the protective cover body 51.
[0086] In this way, when the hot air in the first sub-cavity 5011 passes through the air duct to the second sub-cavity 5012, the hot air is prevented from being discharged through the partition 52 or the area between the air inlet area and the air outlet area of the protective cover body 51, which helps more hot air enter the second sub-cavity 5012, so that more hot air can enter the inner liner 1, thereby improving the drying effect of the hot air in the inner liner 1.
[0087] like Figure 1-Figure 3 As shown, the example of the present utility model also provides a cleaning machine, including an inner tank 1 and a protective cover 5.
[0088] like Figure 3 As shown, a protective cover 5 is provided on the rear wall plate 11 of the inner container 1, and the first sub-cavity 5011 and the second sub-cavity 5012 are arranged side by side on the left and right.
[0089] At least one air inlet hole may be provided on the wall of the first sub-cavity 5011, and at least one air outlet hole may be provided on the wall of the second sub-cavity 5012. Figure 3 As shown, the air outlet can be located in the left area of the inner liner 1, and the air inlet can be located in the right area of the inner liner 1.
[0090] When drying mode is activated, the dishes are dried. Air in the inner container 1 enters the first sub-cavity 5011 through the air inlet. Simultaneously, this air is heated by the heating tube 3 to form hot air. The hot air in the first sub-cavity 5011 flows through the air duct to the second sub-cavity 5012, until it is discharged into the inner container 1 through the air outlet. This hot air gradually diffuses from the left side of the inner container 1 to the right side, distributing it evenly throughout the inner container 1 and improving drying efficiency.
[0091] Since the fan 2 is only provided in the first sub-cavity 5011 , it is avoided that fans 2 are provided in two sub-cavities at the same time, thereby reducing the number of fans 2 and lowering the production cost.
[0092] A water pipe 4 is arranged in the vertical direction on the rear wall plate 11. The water pipe 4 passes through the notch 5105 on the lower side plate 513, the groove 5201 of the partition 52, and the notch 5105 of the upper side plate 512, 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 affecting each other.
