Description

Technical Field

[0001] The utility model generally relates to the technical field of kitchen equipment, and in particular to a cleaning machine. Background Art

[0002] Washing machines can be used for, but are not limited to, washing bowls, chopsticks, plates, dishes, knives, forks, etc. Washing machines on the market can be divided into two categories: household and commercial. Household washing machines mainly include cabinet type, table type, sink-integrated type and integrated type.

[0003] After washing dishes, a washing machine needs to dry them to remove any remaining water stains. In related technologies, washing machines use heat exchange drying to remove residual water stains from dishes. Heat exchange drying works by installing a cold water pipe on the inner tank of the washing machine. The cold water pipe is located on the outer surface of the side wall of the inner tank. The cooling water in the cold water pipe can reduce the temperature of the inner tank's side wall. During the drying stage, because the temperature inside the inner tank is higher than the temperature of the inner tank's side wall, the temperature difference between the two causes water vapor to condense on the inner tank's side wall, thereby removing any remaining water stains from the dishes.

[0004] However, since water vapor condenses on the side walls of the inner container, the side walls of the inner container may remain damp, which can easily breed bacteria. Therefore, tableware is not suitable for long-term storage in the inner container of the washing machine. At the same time, the above drying method has the problem of slow drying speed. Utility Model Content

[0005] The present application hopes to provide a washing machine, which is at least used to shorten the drying time of the washing machine and improve the drying efficiency.

[0006] The utility model provides a cleaning machine, which comprises an inner container.

[0011] As an implementation method, on the first end wall, the first air inlet area is offset toward the first side wall where the first air outlet is provided.

[0012] As an implementation method, a plurality of second air outlet holes are provided on the first end wall at a side of the first air inlet area away from the partition, and the second air outlet holes are located near the corner of the first end wall.

[0013] As an implementable manner, the total area of ​​the second air outlet and the first air outlet is smaller than or equal to the total area of ​​the first air inlet.

[0014] As an implementable method, a second air inlet area is provided on the second end wall of the second sub-cavity, a second air inlet area is provided with a second air inlet hole, a plurality of second side walls are provided around the second end wall, and a third air outlet hole is provided on at least the first side wall away from the first sub-cavity among the plurality of second side walls, and the third air outlet hole is located downstream of the second air inlet hole along the flow direction of the fluid.

The two notches and the groove are connected to form an avoidance groove, and the avoidance groove is stuck outside the water pipe.

[0019] In the above scheme, the fan in this application increases the evaporation rate of residual water by accelerating the air flow in the inner tank, thereby shortening the drying time; the fan in the first sub-cavity can accelerate the air flow in the inner tank space corresponding to the first sub-cavity, and the fan in the second sub-cavity can accelerate the air flow in the inner tank space corresponding to the second sub-cavity, so that the wind in each area of ​​the inner tank can flow faster, and the residual water stains on the side walls of the inner tank can also evaporate, thereby avoiding the breeding of bacteria due to moisture inside the inner tank; at the same time, the two fans work together to make the air in the inner tank flow evenly, which helps to improve the drying effect.

[0033] 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.

[0034] 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.

[0035] At least see Figures 1-6 As shown, the example of the present invention provides a cleaning machine, including an inner tank 1 and a protective cover 5.

[0036] like Figure 1 、 Figure 2 and Figure 3 As shown, a protective cover 5 is provided on the rear cavity plate 11 of the inner tank 1 , and a water pipe 4 is provided on the rear cavity plate 11 in a vertical direction.

[0037] The protective cover 5 includes a protective cover body 51 and a partition 52 .

[0038] The protective cover body 51 has a cavity 501 .

[0039] 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, wherein the side wall is arranged around the edge of the end wall 511 to form the above-mentioned cavity 501. Two oppositely arranged notches are arranged on the side wall of the cavity 501.

[0040] A partition 52 is disposed in the cavity 501 .

[0041] Among them, the separator 52 and the protective cover body 51 can be welded, the separator 52 and the protective cover body 51 can be threaded, the separator 52 and the protective cover body 51 can be inserted, the separator 52 and the protective cover body 51 can be snap-connected, etc., which are not listed one by one in this embodiment.

[0042] 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.

[0043] Among them, Figure 1 and Figure 2 As shown, when the protective cover 5 is used in a washing machine, which may be a dishwasher, the first fan 2 may be disposed in the first sub-cavity 5011, and the second fan 3 and the first heating tube 6 may be disposed in the second sub-cavity 5012. Alternatively, the first fan 2 and the first heating tube 6 may be disposed in the first sub-cavity 5011, and only the second fan 3 may be disposed in the second sub-cavity 5012.

[0044] In the present application, the fan increases the evaporation rate of residual water by accelerating the air flow in the inner liner 1, thereby shortening the drying time; the fan in the first sub-cavity 5011 can accelerate the air flow in the inner liner 1 space corresponding to the first sub-cavity 5011, and the fan in the second sub-cavity 5012 can accelerate the air flow in the inner liner space corresponding to the second sub-cavity 5012, so that the wind in each area of ​​the inner liner 1 can flow faster, and the residual water stains on the side walls of the inner liner 1 can also evaporate, thereby avoiding the breeding of bacteria due to the moisture inside the inner liner 1; at the same time, the two fans work together to make the air in the inner liner flow evenly, which helps to improve the drying effect.

[0045] In the following examples, a first fan 2 may be provided in the first sub-cavity 5011 , and a second fan 3 and a first heating tube 6 may be provided in the second sub-cavity 5012 .

[0046] 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, the second fan 3 and the first heating tube 6 can be suppressed.

[0047] 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 protective cover 5 cannot be installed on the rear cavity plate 11 of the cleaning machine, so as to cover the first fan 2 in the first sub-cavity 5011 and the second fan 3 and the first heating tube 6 in the second sub-cavity 5012 respectively, 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.

[0048] The separator 52 has a groove 5201 extending along the width of the protective cover body 51. The line connecting the two notches is in the same direction as the length of the groove 5201. The two notches and the groove 5201 are connected to form an escape groove 502, which is stuck outside the water pipe 4.

[0049] 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 cavity plate 11 of the inner container 1. Since the protective cover body 51 is also located on the rear cavity plate 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 affect each other, the water pipe 4 passes through 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 affecting each other.

[0050] 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.

[0051] 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 cavity plate 11 of the inner tank 1.

[0052] The protective cover body 51 may be made of, but is not limited to, stainless steel.

[0053] The protective cover body 51 can be formed by, but is not limited to, sheet metal processing or stamping processing.

[0054] 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.

[0055] The separator 52 may be made of, but is not limited to, stainless steel.

[0056] The separator 52 can be formed by, but is not limited to, sheet metal processing or stamping processing.

[0057] It should be noted that, depending on the specific location of the tableware on the shelf, one of the left and right sides can be set as a drying module, while the other is only equipped with a fan, which can accelerate the air flow in the inner container 1 and thus improve the drying effect. This helps to reduce energy consumption.

[0058] As an implementation method, a first air inlet area is provided on the first end wall 511a of the first sub-cavity 5011, and a first air inlet hole 50111 is provided in the first air inlet area. A plurality of first side walls are provided around the first end wall 515a, and a first air outlet hole 50112 is provided on at least the first side wall away from the second sub-cavity 5012 among the plurality of first side walls. Along the flow direction of the fluid, the first air outlet hole 50112 is located downstream of the first air inlet hole 50111, or / and,

[0059] A second air inlet area is provided on the second end wall 511b of the second sub-cavity 5012, and a second air inlet hole 50121 is provided in the second air inlet area. A second air inlet hole 50121 is provided in the second air inlet area, and a plurality of second side walls are provided around the second end wall 511b. Among the plurality of second side walls, at least a third air outlet hole 50122 is provided on the first side wall away from the first sub-cavity 5011, and one of them is away from the first sub-cavity 5011. Along the flow direction of the fluid, the third air outlet hole 50122 is located downstream of the second air inlet hole 50121.

[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 and include 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 are 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] The upper end and the lower end of the partition 52 are respectively in contact with the side walls of the cavity 501 , and the third connecting plate 523 of the partition 52 is in contact with the end wall 511 of the cavity 501 .

[0062] 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.

[0063] 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.

[0064] 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 .

[0065] 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 .

[0066] A first air inlet area is provided on the first end wall 511a, and 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. The plurality of first air inlet holes 50111 can be arranged in a circular array or a rectangular array.

[0067] 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 .

[0068] 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 path, preventing steam overflow.

[0069] 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.

[0070] like Figure 4 and Figure 5 As shown, third 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 .

[0071] like Figure 3 As shown, the second fan 3 rotates, causing the 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 third air outlet 50122). This forms a second internal circulation path, preventing steam overflow.

[0072] In addition, since 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 are all located away from the second sub-cavity 5012, 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 are all located away from the first sub-cavity 5011, thus suppressing the mutual influence between the first internal circulation path and the second internal circulation path.

[0073] Furthermore, the first air inlet area is offset on the first end wall 511a toward the first side wall where the first air outlet 50112 is provided, or / and the second air inlet area is offset on the second end wall 511b toward the second side wall where the third air outlet 50122 is provided.

[0074] like Figure 4 As shown, by setting the first air inlet area close to the left side of the first end wall 511a, the first internal circulation path is helped to deviate to the left side; by setting the second air inlet area close to the right side of the second end wall 511b, the second internal circulation path is helped to deviate to the right side, further suppressing the mutual influence between the first internal circulation path and the second internal circulation path.

[0075] 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 mode 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 can be symmetrically arranged about the partition 52.

[0076] The total area of ​​the first air outlet holes 50112 is equal to the total area of ​​the third air outlet holes 50122. The first air outlet holes 50112 and the third air outlet holes 50122 may be symmetrically arranged with respect to the partition 52.

[0077] 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.

[0078] Furthermore, a plurality of second air outlet holes 50113 are provided on the first end wall 511a at a side of the first air inlet area away from the partition 52, and the second air outlet holes 50113 are located near the corner of the first end wall 511a, or / and,

[0079] A plurality of fourth air outlet holes 50123 are provided on the second end wall 511 b at a side of the second air inlet area away from the partition 52 , and the fourth air outlet holes 50123 are located near a corner of the second end wall 511 b .

[0080] like Figure 4 and Figure 5As shown, since the second air outlet 50113 is arranged away from the second sub-cavity 5012 and the fourth air outlet 50123 is arranged away from the first sub-cavity 5011, it helps to suppress the mutual influence between the first internal circulation path and the second internal circulation path.

[0081] Among them, Figure 4 and Figure 5 As shown, the arrangement of the second air outlet holes 50113 and the arrangement of the fourth air outlet holes 50123 can be the same, and the second air outlet holes 50113 and the fourth air outlet holes 50123 can be symmetrically arranged about the partition 52.

[0082] As a feasible method, the sum of the total area of ​​the second air outlet holes 50113 and the total area of ​​the first air outlet holes 50112 is less than or equal to the total area of ​​the first air inlet holes 50111. This can make the hot air discharged from the air outlet holes have a higher wind pressure and a faster flow rate, so that the hot air can flow more fully in the inner liner 1.

[0083] As a feasible method, the sum of the total area of ​​the fourth air outlet 50123 and the total area of ​​the third 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.

[0084] As an achievable method, Figure 4 and Figure 5 As shown, the end wall 511 of the cavity 501 is located between the second air inlet area and the first air inlet area to form a closed area, and no air outlet is provided in the closed area. This helps to suppress the mutual influence between the first internal circulation path and the second internal circulation path.

[0085] In the present application, the first fan 2 and its corresponding first air inlet 50111, first air outlet 50112, and second air outlet 50113 form a first internal circulation path, and the second fan 3 and its corresponding second air inlet 50121, third air outlet 50122, and fourth air outlet 50123 form a second internal circulation path. The first and second internal circulation paths can jointly dry the dishes in the inner container 1, improving drying efficiency. Since the first sub-cavity 5011 and the second sub-cavity 5012 are independent of each other, this helps to suppress mutual interference between the second internal circulation path and the first internal circulation path, thereby avoiding affecting drying efficiency.

[0086] 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.
