[0045] 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.

[0046] 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.

[0047] See also Figures 1 to 16 As shown, the present invention provides a cleaning machine, comprising:

[0048] An inner container 1, wherein the inner container 1 has a rear wall panel 11;

[0049] The fan 2 has an impeller 21 located in the inner tank 1. The impeller 21 is arranged to rotate about its own axis, and the rotation axis of the impeller 21 extends forward and backward;

[0050] The heating tube 3 includes a heating section 31, which is an open ring. The impeller 21 is located within the open ring. A connecting section 32 is provided at at least one end of the heating section. The connecting section 32 is fixedly provided on the rear wall plate 11 and is arranged at an acute angle to the rotation axis of the impeller 21.

[0051] Specifically, 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 washed; in actual application, in order to improve the cleaning ability of the dishwasher, the inner tank 1 is provided with a plurality of vertical and horizontal grooves (such as the inner tank 1 is provided with a plurality of vertical grooves) and a plurality of vertical grooves. 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 tank 1. In order to realize the cleaning, drying, and disinfection functions of the cleaning machine, the rear wall panel 11 is usually provided with functional components such as a fan 2. The fan 2 and the heating tube 3 cooperate to form a hot air device, which can blow hot air from the back to the front into the inner tank 1 to dry the kitchen utensils in the inner tank 1 and improve the disinfection and sterilization level of the kitchen utensils. The rear wall panel 11 and the inner tank 1 can be integrally formed. Of course, the rear wall panel 11 and the inner tank 1 can also be connected by any connection method, such as but not limited to welding, riveting or clamping, etc. The embodiments of the present application do not specifically limit this.

[0053] The fan 2 has an impeller 21 located in the inner tank 1. The impeller 21 is arranged to rotate about its own axis, and the rotation axis of the impeller 21 extends forward and backward. During the rotation of the impeller 21, hot air is sent into the inner tank 1 to dry kitchen utensils and the like.

[0054] The heating tube 3 has a heating section 31 located in the inner pot 1. The heating section 31 is an open ring. The impeller 21 is located in the open ring. The hot air is centrifugally thrown out by the impeller 21 of the fan 2, and then heated by the heating section 31 and sent into the inner pot 1, quickly raising the temperature in the inner pot 1. A connecting section 32 is fixed at one or both ends of the heating section 31. The connecting section 32 and the heating tube 3 can be integrally formed or fixedly connected. The connecting section 32 is fixedly penetrated on the rear wall plate 11 to support the heating section 31. The extension line of the connecting section 32 forms an angle with the rotation axis of the impeller 21. Setting, Angle is an acute angle, and its range is , angle It can be any value within this range, for example, the angle is 40°, 50°, 60°, etc. It is understood that Figure 4 and Figure 5As shown, the extension line of the connecting section 32 divides the rotation axis into a first axis section and a second axis section. The first axis section is arranged close to the rear wall plate 11, and the second axis section is arranged 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.

[0055] 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, chopsticks, and plates, as well as other items. 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.

[0056] The cleaning machine provided in the embodiment of the present application is arranged at an acute angle between the connecting section 32 and the rotation axis of the impeller 21, so that the connecting section 32 is inclined relative to the rotation axis, thereby reducing the overall thickness of the heating tube 3, minimizing the space occupied by the inner tank 1 of the cleaning machine, ensuring the capacity for placing kitchen utensils in the inner tank 1, and improving the utilization rate of the space in the inner tank 1.

[0057] In some embodiments, as Figure 3 、 Figure 4 and Figure 16 As shown, the rear wall plate 11 includes an inclined surface 112 , which intersects with the connecting section 32 and fixedly supports the connecting section 32 .

[0058] Specifically, the rear wall panel 11 has an inclined surface 112, which is inclined from the large end of the rear wall panel 11 to the side away from the rotation axis. The large end of the rear wall panel 11 refers to the end surface of the wall panel on the rear wall panel 11 to which the fan 2 is fixed. The connecting section 32 is passed through the inclined surface 112 and is fixed to the inclined surface 112, so that the heating section 31 is fixed obliquely to the large end of the rear wall panel 11 through the connecting section 32. Compared with the vertical fixation of the heating section 31 to the rear wall panel 11, the heating section 31 of the present application is fixed obliquely to the large end of the rear wall panel 11, which can reduce the overall thickness of the heating tube 3, thereby reducing the space occupied by the heating tube 3 in the inner tank 1, and realizing ultra-thin installation of the heating tube 3.

[0059] It should be noted that the intersection setting of the connecting section 32 and the inclined surface 112 means that the connecting section 32 and the inclined surface 112 are set at an angle, and the angle can be any value between 30~120°, preferably any value between 45~90°, for example, such as 45°, 60°, 65°, 70°, 90°, etc.

[0060] Further, such as Figure 3 、 Figure 4 and Figure 16As shown, the connecting section 32 is vertically fixed on the inclined surface 112. Such an arrangement not only satisfies the assembly space requirement of the heating tube 3 in the inner container 1, but also enables ultra-thin installation of the heating tube 3.

[0061] As an achievable method, Figure 4 As shown, the rear wall panel 11 has a discontinuous first wall panel 110 and a second wall panel 111. The first wall panel 110 and the second wall panel 111 are staggered in the front-to-back direction, and the ends of the first wall panel 110 and the second wall panel 111 close to each other are connected to form the inclined surface 112.

[0062] Specifically, the inclined surface 112 is formed by stamping on the rear wall panel 11, that is, the first wall panel 110, the second wall panel 111, and the inclined surface 112 are stamped from the same material, such as stainless steel, to form the rear wall panel 11, which is simple in process and saves costs. Among them, the ends of the first wall panel 110 and the second wall panel 111 that are close to each other are staggered in the front-to-back direction, and the ends of the first wall panel 110 and the second wall panel 111 that are close to each other are connected to form the inclined surface 112. The inclined surface 112 formed by the rear wall panel 11 can make the connecting section 32 and the rotation axis of the impeller 21 be set at an angle. It can be understood that the fan 2 is fixed on the first wall panel 110, the first wall panel 110 is set rearward relative to the second wall panel 111, and the first wall panel 110 forms the large end of the rear wall panel 11, the first wall panel 110 extends in the left-right direction, and the second wall panel 111 extends in the left-right direction or is inclined.

[0063] Further, such as Figures 3 to 5 、 Figure 16 As shown, the fan 2 is fixed on the first wall panel 110, and along the direction of the rotation axis and the extension direction from the first wall panel 110 to the inner tank 1, the leading edge of the impeller 21 away from the side of the first wall panel 110 is protruded relative to the inclined surface 112.

[0064] Specifically, the leading edge of the impeller 21 is arranged to protrude relative to the inclined surface 112, so that the axial position of the heating section 31 of the heating tube 3 is located below the impeller 21. Since most of the air is concentrated in the lower position when it is centrifugally thrown out from the impeller 21, the relative position of the heating section 31 and the impeller 21 can enable the air to more efficiently take away the heat of the heating section 31, making the heat in the inner tank 1 more uniform.

[0065] In other embodiments, Figures 5 to 8 As shown, a wedge-shaped piece 6 is provided on one side of the rear wall plate 11 close to the inner container 1, and the connecting section 32 passes through the wedge-shaped piece 6 and intersects and is fixed with the wedge-shaped piece 6;

[0066] An oblique mounting hole is formed on the rear wall plate 11 , and the wedge-shaped member 6 is passed through the oblique mounting hole, so that the connecting section 32 is arranged at an acute angle relative to the rear wall plate 11 .

[0067] Specifically, an oblique mounting hole is defined in the rear wall 11. The oblique mounting hole is inclined in the same direction as the connecting section 32, and both holes are positioned at an acute angle to the rotation axis of the impeller 21. The connecting section 32 is fixedly connected to the wedge 6, and the two intersect, facilitating secure attachment of the connecting section 32 to the oblique mounting hole in the rear wall 11 via the wedge 6.

[0068] Further, such as Figures 7 and 8 As shown, the wedge-shaped member 6 includes a mounting plate 61 , on which a guide tube 62 is fixedly provided. The guide tube 62 is tilted relative to the mounting plate 61 , and the guide tube 62 is assembled in the oblique mounting hole.

[0069] Specifically, the mounting plate 61 is fixed to the guide hole, preferably integrally formed, and the connecting section 32 obliquely perforates the guide tube 62 of the wedge-shaped member 6, and the guide tube 62 can be fitted into the oblique mounting hole, so that the connecting section 32 is obliquely mounted relative to the rear wall panel 11.

[0070] As an achievable method, Figure 5 and Figure 6 As shown, a sealing member 7 and a supporting member 8 are sequentially provided on the side of the rear wall plate 11 away from the wedge-shaped member 6 , and the guide tube 62 passes through the sealing member 7 and the supporting member 8 in sequence to seal the wedge-shaped member 6 and the rear wall plate 11 .

[0071] Specifically, the guide tube 62 of the wedge-shaped member 6 is assembled in the oblique mounting hole of the rear wall 11, the mounting plate 61 of the wedge-shaped member 6 is attached and fixed to the inner side of the rear wall 11, and the seal 7 is attached and fixed to the outer side of the rear wall 11 under the action of the support member 8, so that the connecting section 32 can be sealed with the rear wall 11, ensuring the sealing inside the inner container 1. The seal 7 can be a rubber gasket or the like.

[0072] As an achievable method, Figures 3 to 5 、 Figure 16 As shown, the fan 2 is fixed on the rear wall plate 11, and the rear wall plate 11 fixed with the fan 2 is provided with a protrusion protruding toward the middle of the inner liner 1, and the side of the protrusion facing the outside of the inner liner 1 forms a recessed portion 113;

[0073] The fan 2 further includes a driving unit 22 , which is assembled in the recessed portion 113 . A rotating shaft of the driving unit 22 passes through the recessed portion 113 and is fixedly connected to the impeller 21 .

[0074] Specifically, the fan 2 is fixed to the large end of the rear wall 11 and further includes a drive unit 22. The output shaft of the drive unit 22 is fixedly connected to the impeller 21, providing power for the impeller 21 to rotate. The drive unit 22 may be a motor, etc. A recessed portion 113 is formed on the rear wall 11, recessed toward the inner side of the inner tank 1. The drive unit 22 is assembled within the recessed portion 113, reducing the overall thickness of the fan 2 outside the rear wall 11 of the inner tank 1. Combined with the inclined installation of the heating section 31 on the rear wall 11, the overall thickness of the heating tube 3 and fan 2 is minimized, minimizing the internal space occupied by the cleaning machine and ensuring sufficient space for kitchen utensils.

[0075] As an achievable method, Figure 4 As shown, the rear wall plate 11 is fixedly connected to a support frame 9, and the support frame 9 is located at a position where the heating section 31 is away from the connecting section 32. A slot 91 is provided on the support frame 9, and the heating section 31 is assembled in the slot 91 and engaged with the slot 91.

[0076] Specifically, the heating section 31 is an open ring, and a connecting section 32 is provided at one end of the heating section 31, which is installed on the rear wall panel 11 through the connecting section 32 to support and fix the heating section 31; the end of the heating section 31 away from the connecting section 32 is clamped and fixed with the support frame 9, and the support frame 9 fixed on the rear wall panel 11 further strengthens the support and fixation of the heating section 31, thereby improving the firmness of the heating section 31.

[0077] It should be noted that if Figure 1 、 Figure 10 and Figure 14 As shown, the cleaning machine also includes a protective cover 5, which 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 plate 11 through the cover opening. The heating tube 3 and the impeller 21 are located in the cavity 501 of the protective cover 5. An air inlet 56 is provided on the end wall of the protective cover 5, and an air outlet 57 is provided 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, which accelerates air flow and prevents steam overflow. The heating tube 3 and the fan 2 cooperate to send hot air into the inner tank 1 to dry the kitchen utensils in the inner tank 1 and improve the disinfection and sterilization level of the kitchen utensils.

[0078] As an achievable implementation method, Figure 1 、 Figure 10 and Figure 14 As shown, the cavity 501 includes a first sub-cavity 51 and a second sub-cavity 52 arranged side by side horizontally along the rear wall panel 11, and a hot air device is set in at least one of the first sub-cavity 51 and the second sub-cavity 52, and the hot air device includes a heating pipe 3 and a fan 2.

[0079] In some embodiments, as Figures 1 to 9 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.

[0080] 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.

[0081] In other embodiments, Figures 10 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 protective cover body can be welded, the separator 55 and the protective cover body can be threaded, the separator 55 and the protective cover body can be plugged, the separator 55 and the protective cover body can be snap-connected, etc., which are not listed one by one in this embodiment.

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

[0084] It is understood that the heating tube 3 and the fan 2 are located in the first sub-cavity 51, and the first sub-cavity 51 is provided with an air inlet and an air outlet. Another heating tube 3 and a fan 2 can be provided in the second sub-cavity 52 to achieve a double-sided drying operation (such as Figure 14 and Figure 15 Alternatively, only one fan 2 may be provided in the second sub-cavity 52; Alternatively, an ultraviolet lamp (such as Figure 1 and Figure 2 Alternatively, no mechanism is provided in the second sub-cavity 52, as the cavity 501 structure (as shown); Figure 10 and Figure 11 shown).

[0085] 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.

[0086] For example, Figures 1 to 9 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:

[0087] At least Figure 9 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.

[0088] 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.

[0089] like Figure 9 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.

[0090] 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.

[0091] 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 .

[0092] like Figure 9 and Figure 12 As shown, the sidewalls include a first left sidewall 514 , a first lower sidewall 512 , a first right sidewall 513 , a first upper sidewall 511 , a second left sidewall 524 , a second lower sidewall 522 , a second right sidewall 523 and a second upper sidewall 521 .

[0093] 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.
