[0044] 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.

[0045] 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.

[0046] See also Figures 1-11 As shown, the present invention provides a cleaning machine, comprising:

[0047] An inner container 1, wherein the inner container 1 has a rear wall panel 11;

[0048] An air supply system, the air supply system being installed on the rear wall panel 11 and located in the inner container 1, the air supply system being used to provide hot air and blow the hot air into the inner container 1 from the back to the front;

[0049] The rack 7 is arranged in the inner tank 1, and at least two groups of placement positions are arranged on the rack 7 along the front-to-back direction. Each group of placement positions includes a plurality of placement positions arranged along the left-to-right direction. The placement positions are used to place items to be cleaned. The placement positions are arranged through the front-to-back direction so that when the items to be cleaned are placed in the corresponding placement positions, gaps for the hot air to pass through are formed between adjacent items to be cleaned.

[0050] It should be noted that the cleaning machine can be but is not limited to a dishwasher, which can be used to clean kitchen utensils such as bowls, cutlery, and dishes, and other items to be cleaned. Of course, the cleaning machine of the embodiment of the present application can also have functions such as disinfection and drying, freeing hands and improving the user experience.

[0051] Among them, the inner tank 1 is used as the main body of the washing machine to accommodate and place kitchen utensils or other items to be cleaned; in actual application, in order to improve the cleaning ability of the dishwasher, the inner tank 1 is arranged in the up and down directions (such as Figure 1 At least two spray arms and a water pipe 4 are provided (in the direction shown in the figure), and are connected through the water pipe 4 provided in the inner tank 1 to supply water to different spray arms.

[0052] The rear wall panel 11 refers to the wall panel located behind the inner liner 1. In order to realize the cleaning, drying, and disinfection functions of the washing machine, the rear wall panel 11 is usually provided with functional components such as an air supply system. The air supply system can blow hot air from the back to the front into the inner liner 1, so that the hot air in the inner liner 1 flows from the back to the front. The rear wall panel 11 and the inner liner 1 can be integrally formed. Of course, the rear wall panel 11 and the inner liner 1 can also be connected by any other connection method, such as but not limited to welding, riveting, or clamping, etc., and the embodiments of the present application do not specifically limit this.

[0053] The shelf 7 is located inside the inner pot 1, and is provided with at least two groups of placement positions along the front-to-back direction. For example, it includes a first group of placement positions and a second group of placement positions. The first group of placement positions and the second group of placement positions both include multiple placement positions arranged along the left-right direction, wherein the spacing between each placement position in the first group of placement positions may be the same as or different from the spacing between the placement positions in the second group of placement positions. It is preferred to use placement positions of different sizes to meet the placement requirements of kitchen utensils of different sizes.

[0054] Compared to placing the kitchenware sideways (upright), the front of the kitchenware can directly contact the hot air, while the back of the kitchenware cannot, resulting in poor drying effect on the back of the kitchenware. In the embodiment of the present application, each placement position is arranged in a continuous manner along the front-to-back direction, so that the kitchenware can be placed in the inner container 1 along the front-to-back direction (sideways), and when any two adjacent placement positions in the same group of placement positions are placed, a gap is formed between the two adjacent kitchenware. This gap allows the hot air sent into the inner container 1 by the air supply system to pass through, thereby allowing all parts of the kitchenware (front and back) to directly contact the hot air, ensuring that all parts of the kitchenware can achieve a better drying effect.

[0055] The cleaning machine provided in the embodiment of the present application can solve the problem of poor drying effect of kitchen utensils. By setting the placement direction and the flow direction of the hot air blown into the inner tank 1 by the air supply system, the placement direction of the kitchen utensils is the same as the flow direction of the hot air in the inner tank 1, and all parts of the kitchen utensils can directly contact the hot air, ensuring that the kitchen utensils can be fully dried and improving the disinfection and sterilization effect of the kitchen utensils.

[0056] As an achievable method, Figures 2 to 5 As shown, the shelf 7 includes a shelf frame 71, and at least two groups of support members are arranged in the front-to-back direction in the shelf frame 71, each group of support members includes a first row of support frames 701 and a second row of support frames 702 arranged in the front-to-back direction, the first row of support frames 701 and the second row of support frames 702 both include a plurality of support rods 703 arranged at intervals along the left-right direction, the support rods 703 of the first row of support frames 701 and the support rods 703 of the second row of support frames 702 are correspondingly arranged along the front-to-back direction so that the placement position is formed between two adjacent support rods 703 of the first row of support frames 701 and two corresponding support rods 703 of the second row of support frames 702.

[0057] For example, Figures 2 to 5As shown, a first group of supports and a second group of supports are provided in the shelf 7, and the first group of supports and the second group of supports are arranged in the front-to-back direction. The first group of supports and the second group of supports both include a first row of support frames 701 and a second row of support frames 702 spaced apart in the front-to-back direction, wherein the spacing between the first row of support frames 701 and the second row of support frames 702 matches the length of the kitchen utensils. The spacing between the first row of supports and the second row of supports in the first group of supports and the second group of supports may be the same or different, preferably different, to meet the placement requirements of kitchen utensils of different sizes.

[0058] Both the first row of support racks 701 and the second row of support racks 702 include a plurality of support rods 703 spaced apart in the left-right direction. The spacing between the support rods 703 can be the same or different. The spacing between the support rods 703 in the first group of support members is different from the spacing between the support rods 703 in the second group of support members, thereby meeting the placement requirements of kitchenware of different sizes and improving the user experience.

[0059] In this example, the support rods 703 in the first row of support racks 701 and the second row of support racks 702 are used to form a placement position that is set through in the front-to-back direction, which is conducive to the cleaning and fixation of kitchen utensils, etc., and the formed placement position can ensure that there are gaps between adjacent tableware for hot air circulation when the kitchen utensils are placed, ensuring that all parts of the kitchen utensils can directly contact the hot air, thereby improving the drying effect of the kitchen utensils.

[0060] As an achievable method, Figure 1 and Figure 6 As shown, the inner container 1 further comprises a first side wall panel 12 and a second side wall panel 13, wherein the first side wall panel 12 and the second side wall panel 13 are respectively located on both sides of the rear wall panel 11 and are both connected to the rear wall panel 11;

[0061] The air supply system includes a protective cover 5 and a hot air device. At least one of the side walls of the protective cover 5 is adjacent to the corresponding first side wall plate 12 or the second side wall plate 13. The corresponding side wall of the protective cover 5 is provided with an air outlet 57, and the hot air device is arranged inside the protective cover 5.

[0062] The inner liner 1 has a cavity structure formed by a rear wall panel 11, a first side wall panel 12 and a second side wall panel 13. The rear wall panel 11 refers to the wall panel located at the rear of the inner liner 1, and the first side wall panel 12 and the second side wall panel 13 refer to the wall panels located on the left and right sides of the inner liner 1. The first side wall panel 12 and the second side wall panel 13 are respectively connected to the rear wall panel 11.

[0063] An air supply system is provided on one side of the rear wall panel 11 located inside the inner container 1. The air supply system includes a protective cover 5 and a hot air device. The protective cover 5 includes an end wall and a side wall. The side wall is arranged around the end wall to form a cavity 501 of the protective cover 5. The protective cover 5 has a cover opening at a position opposite to the end wall, which is arranged on the rear wall panel 11 through the cover opening. The hot air device is located in the cavity 501 of the protective cover 5. The air inlet 56 is opened on the end wall, and the air outlet 57 is opened on the side wall. Along the flow direction of the fluid, the air outlet 57 is located downstream of the air inlet 56. The air outlet 57 and the air inlet 56 form an internal circulation air duct to accelerate the air flow without steam overflow. The air supply device can send dry air into the inner container 1 to dry the kitchen utensils in the inner container 1 and improve the disinfection and sterilization level of the kitchen utensils.

[0064] For example, Figure 8 、 Figure 10 and Figure 12 As shown, the sidewalls of the protective cover 5 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. At least one of the first left sidewall 514 and the second right sidewall 523 is disposed adjacent to the first sidewall panel 12 or the second sidewall panel 13. If the first left sidewall 514 is disposed adjacent to the first sidewall panel 12, the air outlet 57 is disposed on the first left sidewall 514; if the second right sidewall 523 is disposed adjacent to the second sidewall panel 13, the air outlet 57 is disposed on the second right sidewall 523.

[0065] It is understandable that the protective cover 5 is mounted on the rear wall 11 of the inner liner 1 and is located inside the inner liner 1. Since the cleaning machine is usually equipped with functional components such as a hot air device and an ultraviolet lamp on the rear wall 11 in order to achieve functions such as drying and disinfection, the protective cover 5 is at least provided on the functional components such as the hot air device and the ultraviolet lamp in order to protect the functional components such as the hot air device and the ultraviolet lamp. The protective cover 5 can be detachably connected to the rear wall 11. For example, the protective cover 5 is connected to the rear wall 11 by a buckle. Of course, the protective cover 5 can also be connected to the rear wall 11 by a concave-convex fit. The embodiments of the present application do not limit this. The protective cover 5 can be detachably connected, which is conducive to convenient disassembly and assembly, and at the same time facilitates the inspection and maintenance of other functional components such as the hot air device and the ultraviolet lamp.

[0066] Further, such as Figures 6 to 12 As shown, the protective cover 5 extends transversely relative to the rear wall plate 11 , and the side walls at both ends are adjacent to the first side wall plate 12 and the second side wall plate 13 respectively. The hot air device and the air outlet 57 are located on the same side of the protective cover 5 .

[0067] Specifically, the first left side wall 514 of the protective cover 5 extending transversely relative to the rear wall panel 11 is arranged adjacent to the first side wall panel 12, and the second right side wall 523 is arranged adjacent to the second side wall panel 13, wherein the hot air device is offset relative to the rear wall panel 11, and the hot air device and the air outlet 57 are located on the same side of the protective cover 5, so that the air supply system can deliver hot air from the back to the front into the inner tank 1 in a biased air outlet manner, so as to improve the drying effect of the kitchen utensils.

[0068] As an implementable method, the rack 7 includes a first rack and a second rack, wherein the first rack and the second rack are arranged at intervals in the upper and lower directions along the height direction of the inner tank 1; the air outlet 57 is arranged between the first rack and the second rack along the height direction of the inner tank 1.

[0069] In this example, the first and second racks are spaced apart vertically along the height of the inner container 1, improving the utilization of the space within the inner container 1 and allowing more kitchen utensils and the like to be placed therein at one time. The air outlet 57 is positioned between the first and second racks along the height of the inner container 1, allowing the hot air blown into the inner container 1 by the air outlet 57 to be evenly distributed along the height, ensuring that the kitchen utensils on the first and second racks are evenly heated.

[0070] As an achievable method, Figures 7 to 9 As shown, the hot air device includes a fan 2 and a heating tube 3; wherein, the fan 2 has an impeller 21 located in the inner tank 1; the heating tube 3 includes a heating section 31, the heating section 31 is an open ring, and the impeller 21 is located in the open ring.

[0071] Specifically, the hot air device includes a fan 2 and a heating tube 3. The fan 2 is fixed to the rear wall 11. The fan 2 has an impeller 21 located inside the inner liner 1 and a drive unit 22, such as a motor, located outside the inner liner 1. The output shaft of the drive unit 22 passes through the rear wall 11 and is fixedly connected to the impeller 21. The impeller 21 is arranged to rotate about its own axis, and the rotation axis of the impeller 21 extends forward and backward. The heating tube 3 is an open ring. At least one end of the heating section 31 is provided with a connecting section 32. The connecting section 32 is fixedly provided on the rear wall 11. The impeller 21 is located within the open ring. The air in the cavity 501 is centrifugally ejected by the impeller 21 of the fan 2, and then discharged from the air outlet 57 after being heated by the heating tube 3, thereby sending the hot air into the inner liner 1 to quickly increase the temperature within the inner liner 1.

[0072] It is understandable that if Figure 9 As shown, the fan 2 further includes a driving unit 22 , the output shaft of which is fixedly connected to the impeller 21 to provide power for the impeller 21 to rotate, wherein the driving unit 22 may be a motor or the like.

[0073] As an achievable method, Figure 9 As shown, the impeller 21 is arranged to be rotatable about its own axis, and the rotation axis of the impeller 21 is extended forward and backward;

[0074] A connecting section 32 is provided at at least one end of the heating section 31 . The connecting section 32 is provided at an acute angle to the rotation axis of the impeller 21 .

[0075] Specifically, the rotation axis of the impeller 21 is extended forward and backward, and a connecting section 32 is provided at one end or both ends of the heating section 31. The connecting section 32 is tilted relative to the rotation axis, so that the connecting section 32 is set at an angle to the rotation axis, and the connecting section 32 is set at an obtuse angle to the end of the rotation axis close to the protective cover 5, and is set at an acute angle to the end of the rotation axis close to the rear wall plate 11, so that the connecting section 32 of the heating tube 3 is tilted and fixed on the rear wall plate 11, reducing the thickness of the heating device, minimizing the space occupied by the inner tank 1 of the cleaning machine, and ensuring the capacity for placing kitchen utensils in the cleaning machine.

[0076] The extended line of the connecting section 32 and the rotation axis of the impeller 21 form an angle Setting, Angle is an acute angle, and its range is , angle It can be any value within this range, for example, the angle 40°, 50°, 60°, etc. It can be understood that the extension line of the connecting section 32 divides the rotation axis into a first axis segment and a second axis segment. The first axis segment is set close to the side of the rear wall plate 11, and the second axis segment is set away from the rear wall plate 11. It refers to the angle between the extension line of the connecting segment 32 and the first axis segment. Correspondingly, the angle between the extension line of the connecting segment 32 and the second axis segment is an obtuse angle.

[0077] As an implementable manner, the protective cover 5 includes a cavity 501, and the cavity 501 includes a first sub-cavity 51 and a second sub-cavity 52 arranged side by side and independent of each other, and the hot air device is arranged in at least one of the first sub-cavity 51 and the second sub-cavity 52.

[0078] In some embodiments, as Figures 6 to 10 As shown, the protective cover 5 forms a cover opening of the cavity 501 on the first side, and forms an end wall of the cavity 501 on the second side, and the first side and the second side are arranged opposite to each other.

[0079] 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.

[0080] As an implementable manner, the protective cover 5 includes a first sub-cavity 51 and a second sub-cavity 52 which are arranged side by side and communicated with each other, and the hot air device is arranged in one of the first sub-cavity 51 and the second sub-cavity 52 .

[0081] In other embodiments, Figures 11 to 13 As shown, the partition 55 is connected to the protective cover 5 and is at least partially located in the cavity 501, and is used to divide the cavity 501 into a first sub-cavity 51 and a second sub-cavity 52 arranged side by side, and the partition 55 is arranged close to the cover opening of the cavity 501 to leave a gap between it and the end wall of the cavity 501 to form an air duct.

[0082] Among them, the separator 55 and the main body of the protective cover 5 can be welded, the separator 55 and the main body of the protective cover 5 can be threaded, the separator 55 and the main body of the protective cover 5 can be plugged, the separator 55 and the main body of the protective cover 5 can be snap-connected, etc., which are not listed one by one in this embodiment.

[0083] In some embodiments, the divider 55 is disposed within the cavity 501, with a gap between the divider 55 and the end wall, which can serve as an air duct. In another embodiment, the divider 55 is disposed within the cavity 501, with a gap between the divider 55 and the side wall, which can serve as an air duct. In yet another embodiment, the divider 55 is disposed within the cavity 501, with no gap between the divider 55 and the end wall or side wall, and a through hole is provided in the divider 55, which can serve as an air duct.

[0084] As an implementable manner, the hot air device is provided in both the first sub-cavity 51 and the second sub-cavity 52;

[0085] Alternatively, the hot air device is provided in one of the first sub-cavity 51 and the second sub-cavity 52, and a disinfection lamp is provided in the other sub-cavity;

[0086] Alternatively, the hot air device is disposed in one of the first sub-cavity 51 and the second sub-cavity 52 , and the fan 2 is disposed in the other sub-cavity.

[0087] It is understood that the hot air device is located in the first sub-cavity 51, and the first sub-cavity 51 is provided with an air inlet 56 and an air outlet 57. Another hot air device can be provided in the second sub-cavity 52; or, only one fan 2 can be provided in the second sub-cavity 52; or, an ultraviolet lamp can be provided in the second sub-cavity 52; or, the second sub-cavity 52 can be provided with no mechanism, and serve as a cavity structure.

[0088] In the embodiment of the present application, the protective cover 5 having the first sub-cavity 51 and the second sub-cavity 52 can be simultaneously installed to cover two hot air devices; or simultaneously install the hot air device and the blower 2; or simultaneously install the hot air device and the ultraviolet lamp; or install the hot air device to form a single cavity 501. This avoids the need to install the protective cover 5 separately, thereby improving the assembly efficiency of the cleaning machine.

[0089] For example, Figures 1 to 10 As shown, the hot air device is located in the first sub-cavity 51 and the ultraviolet lamp is located in the second sub-cavity 52 for illustration:

[0090] At least Figure 10 As shown, the protective cover 57 forms a cover opening of the cavity 501 on the first side, and the protective cover 5 forms an end wall of the cavity 501 on the second side, and the first side and the second side are arranged opposite to each other.

[0091] 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.

[0092] like Figure 10 As shown, a recessed portion 53 is provided in the middle of the protective cover 5, which extends downward to the bottom of the avoidance groove 54. The middle portion of the end wall is recessed from front to back to form this recessed portion 53. 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. This prevents any interference between the fan 2, the heating tube 3, and the UV lamp.

[0093] The recessed portion 53 is located in the middle of the end wall in the left-right direction. The recessed portion 53 can be a long groove. The long groove can extend in the vertical direction and pass through the protective cover 5. In other words, the upper and lower ends of the long groove are open. Of course, it is understood that the groove portion can have other structures, which are not listed in this embodiment.

[0094] The long groove divides the end wall into two parts, wherein the end wall area located on the left side of the long groove is the first end wall 515 , and the end wall area located on the right side of the long groove is the second end wall 525 .

[0095] like Figure 10 and Figure 12 As shown, 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 right side wall 513.

[0096] 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 left side wall 524.

[0097] By providing the recessed portion 53, the overall rigidity and strength of the protective cover 5 can also 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 5, and thus making it impossible to install the protective cover 5 on the rear wall panel 11 of the cleaning machine, or preventing the blades of the fan 2 from scratching against the cavity wall of the first sub-cavity 51 during rotation, or preventing the second sub-cavity 52 from deforming and contacting the ultraviolet lamp installed therein, causing damage to the ultraviolet lamp.

[0098] The protective cover 5 can be made of, but is not limited to, stainless steel.

[0099] The protective cover 5 can be made of, but is not limited to, a sheet metal process or a stamping process.

[0100] The protective cover 5 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, forming the protective cover 5 with 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, simplifying and facilitating processing, and helping to reduce production costs.

[0101] In addition, if Figure 1 、 Figure 6 、 Figure 7 and Figure 11 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. The protection cover 5 is provided with an avoidance groove 54, so that the water pipe 4 can pass through the avoidance groove 54 and the protection cover 5, so that the installation of the protection cover 5 and the water pipe 4 does not affect each other.

[0102] 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.
