[0002] A washing machine is a device that automatically washes bowls, chopsticks, plates, dishes, knives, forks and other tableware. The fully automatic washing machines on the market can be divided into two categories: household and commercial. Household fully automatic washing machines are only suitable for households, and are mainly cabinet-type, desktop-type, sink-integrated and integrated types.

[0003] In a washing machine, air is blown into the inner chamber during the drying phase to improve the drying effect. The drying mechanism typically consists of a centrifugal fan and a heater, which is positioned around the fan. The fan draws air from the inner chamber of the washing machine, which is then heated by the heater before entering the inner chamber. The hot air dries and evaporates water from the inner chamber and the dishes, preventing moisture and odor from forming inside the inner chamber.

[0004] In the related art, a drying device is provided on the left and right sides of the inner tank, and each drying device is provided with a protective cover. However, this method is costly and complicated to install, which affects the assembly efficiency of the washing machine. Utility Model Content

[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 1-17 As shown, the present invention provides a washing machine, comprising: an inner tank 1, a protective cover 5, a water pipe 4 and at least one hot air device. The washing machine can be a dishwasher.

[0038] A protective cover 5 is provided on the rear cavity plate 11 of the liner 1, and the protective cover 5 is detachably connected to the rear cavity plate 11. For example, the protective cover 5 is threadedly connected to the rear cavity plate 11, the protective cover 5 is threadedly snap-connected to the rear cavity plate 11, the protective cover 5 is threadedly inserted into the rear cavity plate 11, and the like.

[0039] The water pipe 4 is vertically arranged on the rear cavity plate 11 .

[0040] The protective cover 5 includes a main body, which includes a cavity 501. The main body has two circumferentially opposed notches, oriented in the same direction as the opening of the cavity 501. The two notches extend through the main body to form a bypass groove 54. The bypass groove 54 corresponds to the water pipe 4 and is located outside the water pipe 4.

[0041] The cavity 501 includes a first sub-cavity 51 and a second sub-cavity 52 arranged side by side. A hot air device is located in the first sub-cavity 51, and the first sub-cavity 51 is provided with an air inlet and an air outlet. Another hot air device can be installed in the second sub-cavity 52, and the hot air device includes a fan 2 and a heating tube 6, and the heating tube 6 surrounds the fan 2; alternatively, only a fan 2 can be installed in the second sub-cavity 52; alternatively, a disinfection lamp 3 can be installed in the second sub-cavity 52; alternatively, no mechanism is installed in the second sub-cavity 52, and the cavity 501 structure is formed.

[0042] The present invention uses a protective cover 5 with a first sub-cavity 51 and a second sub-cavity 52 to simultaneously cover two hot air devices; or simultaneously cover the hot air device and the blower 2; or simultaneously cover the hot air device and the disinfection lamp 3; or cover the hot air device and form a single cavity 501. This avoids the need for separate installation of the protective cover 5, thereby improving the assembly efficiency of the cleaning machine.

[0043] In detail, such as Figure 1-Figure 5As shown, the hot air device is located in the first sub-cavity 51 and the disinfection lamp 3 is located in the second sub-cavity 52 for illustration:

[0044] At least Figure 4 and Figure 5 As shown, the protective cover body forms an 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.

[0045] 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.

[0046] like Figure 5 As shown, a recessed portion 53 is provided in the middle of the protective cover body, 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 interference between the fan 2, the heating tube 6, and the disinfection lamp 3.

[0047] 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 vertically and penetrate the protective cover body, that is, 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.

[0048] 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 .

[0049] like Figure 4 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 .

[0050] 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.

[0051] 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.

[0052] By providing the recessed portion 53, the overall rigidity and strength of the protective cover body can 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 body, and making it impossible to install the protective cover 5 on the rear cavity plate 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 disinfection lamp 3 installed therein, causing damage to the disinfection lamp 3.

[0053] The protective cover body can be made of, but is not limited to, stainless steel.

[0054] The protective cover body can be made of, but is not limited to, sheet metal processing or stamping processing.

[0055] The protective cover body 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 body 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 convenient processing and helping to reduce production costs.

[0056] In addition, if 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 tank 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.

[0057] As an implementable method, an air inlet area is provided on the first end wall 515 of the first sub-cavity 51, and a first air inlet hole 5101 is provided in the air inlet area. A plurality of first side walls are provided around the first end wall 515, and a first air outlet hole 5102 is provided on at least one of the plurality of first side walls, and one of the plurality of first side walls is away from the second sub-cavity 52.

[0058] like Figure 3 and Figure 4 As shown, an air inlet area is provided on the first end wall 515, and a plurality of first air inlet holes 5101 are provided in the air inlet area. The air inlet area can be arranged directly opposite the fan 2 to shorten the air inlet path, reduce air inlet resistance, and increase air inlet volume. The plurality of first air inlet holes 5101 can be arranged in a circular array or a rectangular array.

[0059] Because the first left side wall 514, the first lower side wall 512, and the first upper side wall 511 are all located away from the second sub-cavity 52, a plurality of first air outlet holes 5102 are correspondingly provided on the first left side wall 514, the first lower side wall 512, and the first upper side wall 511. The plurality of first air outlet holes 5102 can be arranged in a circular array or a rectangular array. The first right side wall 513, however, is located closer to the second sub-cavity 52 and does not have any first air outlet holes 5102.

[0060] In this way, each of the first air outlet holes 5102 is not directed toward the second sub-cavity 52 , thereby suppressing the influence of the fan 2 on the disinfection lamp 3 .

[0061] In actual application, the total area of ​​the first air outlet holes 5102 of any one of the first left side wall panel 514, the first lower side wall panel 512, and the first upper side wall panel 511 is smaller than the total area of ​​the first air inlet holes 5101 in the first end wall 515. The larger wind pressure can transport the hot air to all corners of the inner liner 1 more quickly, so that more hot air can be discharged from the bottom of the protective cover 5.

[0062] In one embodiment, Figure 4 As shown, the air inlet area is offset on the first end wall 515 in a direction away from the second sub-cavity 52. ​​In this way, each first air outlet 5102 is further away from the second sub-cavity 52, further suppressing the influence of the fan 2 on the disinfection lamp 3.

[0063] As an implementable manner, at least one circle of first profile 5105 is provided on the first end wall 515 around the air inlet area.

[0064] Specifically, if Figure 3 、 Figure 4 and Figure 5 As shown, the first press profile 5105 can be an annular groove that is recessed from front to back in a local area of ​​the first end wall 515. Alternatively, the first press profile 5105 can be an annular protrusion that is protruded from back to front in a local area of ​​the first end wall 515.

[0065] At least one first profile 5105 is provided on the first end wall 515, surrounding the air inlet area. The first profile 5105 enhances the rigidity and strength of the first end wall 515, ensuring its flatness and reducing the likelihood of the fan 2 blades rubbing against it due to deformation of the first end wall 515.

[0066] It should be noted that when the protective cover body is formed by a stamping process, the first pressing profile 5105 can be formed by stamping.

[0067] In one embodiment, along the direction from the opening of the first sub-cavity 51 to the first end wall 515 , the height of the portion of the first end wall 515 corresponding to the air inlet area is higher than the height of the remaining portion of the first end wall 515 .

[0068] Specifically, at least Figure 4 and Figure 5 In the example, the air inlet area of ​​the first end wall 515 protrudes a distance from the back to the front, so that the air inlet area of ​​the first end wall 515 and the area of ​​the first end wall 515 except the air inlet area are not on the same plane. This increases the distance between the air inlet area and the blades of the fan 2, and reduces the probability that the blades of the fan 2 will scratch the first end wall 515 due to the deformation of the first end wall 515.

[0069] As an implementation, a first light exit hole 5201 and a plurality of second light exit holes 5202 are provided on the second end wall 525 of the second sub-cavity 52. ​​The first light exit hole 5201 is an elongated hole, that is, a strip-shaped light exit hole. The second light exit holes 5202 are radially arranged around the first light exit hole 5201.

[0070] Specifically, if Figure 1 、 Figure 2 and Figure 4 As shown, a disinfection lamp 3 is provided in the second sub-cavity 52 and is arranged along the left and right directions. Correspondingly, a first light exit hole 5201 and a second light exit hole 5202 are provided on the second end wall 525 .

[0071] The first light exit hole 5201 is an elongated hole corresponding to the disinfection lamp 3. The second light exit holes 5202 are located in the area of ​​the second end wall 525 close to the second lower side wall 522 and the area of ​​the second end wall 525 close to the second upper side wall 521.

[0072] The first light exit hole 5201 and the second light exit hole 5202 make the light exit area on the second end wall 525 larger, which helps the disinfection lamp 3 to emit more light, thereby improving the sterilization effect.

[0073] The first light exit hole 5201 and the second light exit hole 5202 are offset on the second end wall 525 toward the first sub-cavity 51. In this way, the light from the disinfection lamp 3 can reach directly in front of the first sub-cavity 51, thereby expanding the coverage area of ​​the light.

[0074] In addition, a second press profile 5204 is provided on the second end wall 525 , and two second press profiles 5204 are respectively located at two ends of the first light exit hole 5201 .

[0075] Specifically, if Figure 3 and Figure 4As shown, the second protrusion 5204 can be a groove that is concave from front to back along a portion of the second end wall 525. Alternatively, the first protrusion 5105 can be a protrusion that is convex from back to front along a portion of the first end wall 515. The groove and protrusion can be in the shape of an arcuate strip. Of course, it is understood that the groove and protrusion can also have other shapes, which are not listed in this embodiment.

[0076] The second profile 5204 improves the rigidity and strength of the second end wall 525, helps maintain its flatness, and reduces the probability of damage to the disinfection lamp 3 due to deformation of the second end wall 525. Furthermore, the second profile 5204 shields the end of the disinfection lamp 3, improving the aesthetics of the inner container 1.

[0077] It should be noted that when the protective cover body is formed by a stamping process, the second pressing profile 5204 can be formed by stamping.

[0078] As an achievable method, Figure 4 As shown, at least one circle of third profile 5205 is further provided on the second end wall 525 of the second sub-cavity 52 , and the second profile 5204 , the first light exit hole 5201 and the second light exit hole 5202 are respectively located in the area surrounded by the third profile 5205 .

[0079] It should be noted that the structure of the third press profile 5205 can refer to the structure description of the first press profile 5105, so it will not be repeated. When the protective cover body is formed by a stamping process, the third press profile 5205 can be formed by stamping.

[0080] The provision of the third profile 5205 can improve the rigidity and strength of the second end wall 525 , help the second end wall 525 to ensure its flatness, and reduce the probability of the disinfection lamp 3 being damaged due to deformation of the second end wall 525 .

[0081] As an implementation method, a plurality of second sidewalls are disposed around the second end wall 525 of the second sub-cavity 52 , at least one of the plurality of second sidewalls is provided with a third light exit hole 5203 , and one of the second sidewalls is away from the first sub-cavity 51 .

[0082] like Figure 4 As shown, since the second lower sidewall 522, the second right sidewall 523, and the second upper sidewall 521 are all located away from the first sub-cavity 51, a plurality of third light exit holes 5203 are provided on the second lower sidewall 522, the second right sidewall 523, and the second upper sidewall 521. However, the second left sidewall 524 is located closer to the first sub-cavity 51 and does not have any third light exit holes 5203.

[0083] The setting of the third light emitting hole 5203, on the one hand, further helps the disinfection lamp 3 to emit more light, further improving the sterilization effect; on the other hand, since the second lower side wall 522, the second right side wall 523 and the second upper side wall 521 are all set away from the first sub-cavity 51, although the second left side wall 524 is close to the first sub-cavity 51, the third light emitting hole 5203 is not set thereon, so that the light will not be irradiated to the first sub-cavity 51, thereby suppressing the influence of the disinfection lamp 3 on the fan 2 and the heating tube 6.

[0084] In detail, such as Figures 6-10 As shown, the hot air device is located in the first sub-cavity 51, the second sub-cavity 52 is not provided with any mechanism, an air duct is provided between the first sub-cavity 51 and the second sub-cavity 52, and air outlet holes are provided on the second end wall 525 and / or the second side wall of the second sub-cavity 52.

[0085] The protective cover body forms an opening of the cavity 501 on the first side, and forms an end wall of the cavity 501 on the second side. The first side and the second side are arranged opposite to each other.

[0086] like Figure 9-10 As shown, the first partition 55 is connected to the protective cover body 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. In addition, the first partition 55 is arranged close to the opening of the cavity 501 to leave a gap between it and the end wall of the cavity 501 to form an air duct.

[0087] Among them, the first partition 55 and the protective cover body can be welded, the first partition 55 and the protective cover body can be threaded, the first partition 55 and the protective cover body can be plugged, the first partition 55 and the protective cover body can be snap-connected, etc., which are not listed one by one in this embodiment.

[0088] In one embodiment, the first partition 55 is disposed within the cavity 501, and a gap exists between the first partition 55 and the end wall, which can serve as an air duct. In another embodiment, the first partition 55 is disposed within the cavity 501, and a gap exists between the first partition 55 and the side wall, which can serve as an air duct. In yet another embodiment, the first partition 55 is disposed within the cavity 501, and no gap exists between the first partition 55 and the end wall or side wall, and the first partition 55 is provided with a through hole, which can serve as an air duct.

[0089] Among them, at least Figure 6 、 Figure 9 、 Figure 10As shown, the first partition 55 is long and is located in the middle position of the cavity 501 in the left-right direction. The length of the first partition 55 extends along the up-down direction of the cavity 501 until the upper end of the first partition 55 fits seamlessly with the upper side wall of the cavity 501; the lower end of the first partition 55 fits seamlessly with the upper side wall of the cavity 501, and the first partition 55 is spaced and parallel to the end wall of the cavity 501, so that the above-mentioned air duct is formed between the first partition 55 and the protective cover body.

[0090] like Figure 9 or Figure 10 As shown, the end wall region located on the left side of the first partition 55 is the first end wall 515 ; the end wall region of the cavity located on the right side of the first partition 55 is the second end wall 525 .

[0091] 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 .

[0092] 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 the first left side wall 514, the first lower side wall 512, and the first upper side wall 511 are 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 first partition 55 share the first right side wall 513.

[0093] 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 the second lower side wall 522, the second right side wall 523, and the second upper side wall 521 are arranged around the edge of the second end wall 525, thereby forming the second sub-cavity 52. ​​It should be noted that the second sub-cavity 52 and the first partition 55 share the second left side wall 524.

[0094] like Figure 1 、 Figure 2 As shown, the water pipe 4 is arranged in the vertical direction and is located on the rear cavity plate 11 of the inner tank 1. The first partition 55 is provided with a first groove 551 through which the water supply pipe 4 passes. The length extension direction of the first groove 551 is the same as the length extension direction of the avoidance groove 54. The water pipe 4 passes through the avoidance groove 54 and the first groove 551 of the first partition 55, 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. In addition, the first partition 55 also protects the water pipe 4. The first partition 55 can block the contact between hot air and the water pipe 4, suppress the impact of hot air on the water pipe 4, and help to extend the service life of the water pipe 4.

[0095] As an implementation method, the first end wall 515 of the first sub-cavity 51 is provided with an air inlet area, and a plurality of first air inlet holes 5101 are provided on the air inlet area. The first end wall 515 is provided with a plurality of first side walls around it, and at least one of the plurality of first side walls is provided with a first air outlet hole 5102, and one of the first side walls is away from the second sub-cavity 52.

[0096] The second end wall 525 of the second sub-cavity 52 defines an air outlet area with a plurality of fourth air outlet holes 52061 disposed therein. A plurality of second side walls are disposed around the second end wall 525, and at least one of the plurality of second side walls defines a fifth air outlet hole 5207, one of which is located away from the first sub-cavity 51.

[0097] Along the flow direction of the fluid, the fourth air outlet 52061 is located downstream of the first air inlet 5101 .

[0098] like Figure 9 or Figure 10 As shown, a plurality of first air inlet holes 5101 are provided in the air inlet area on the first end wall 515. The air inlet area is 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. Each first air inlet hole 5101 may have the same or different shapes and sizes.

[0099] An air outlet area is provided on the second end wall 525, and a plurality of fourth air outlet holes 52061 are provided in the air outlet area. The plurality of fourth air outlet holes 52061 can be arranged in a rectangular array or an annular array. The fourth air outlet holes 52061 can be of the same or different shapes and sizes.

[0100] like Figure 6-Figure 8 As shown, when fan 2 is activated, air in inner liner 1 enters first sub-cavity 51 through first air inlet 5101. Simultaneously, this air is heated by heating tube 3 to form hot air. The hot air in first sub-cavity 51 flows through the air duct to second sub-cavity 52, until it is discharged through fourth air outlet 52061, where it can flow along the front of inner liner 1. This hot air gradually diffuses from the right side of inner liner 1 to the left side, distributing the hot air evenly throughout inner liner 1 and improving drying efficiency.

[0101] In addition, the fan 2 is only provided in the first sub-cavity 51 , which avoids providing fans 2 in two sub-cavities at the same time, reduces the number of fans 2 , and thus lowers production costs.

[0102] In addition, if Figure 9 and Figure 10As shown, since the second lower sidewall 522, the second right sidewall 523, and the second upper sidewall 521 are all located away from the first sub-cavity 51, a plurality of fifth air outlet holes 5207 are provided on each of the second lower sidewall 522, the second right sidewall 523, and the second upper sidewall 521. However, the second left sidewall 524 is located closer to the first sub-cavity 51 and is not provided with the fifth air outlet holes 5207.

[0103] The provision of the fifth air outlet 5207 allows more hot air to be discharged through the fifth air outlet 5207. Since the second lower side wall 522, the second right side wall 523, and the second upper side wall 521 are all disposed away from the first sub-cavity 51, the hot air can gradually diffuse from the right area to the left area of ​​the inner liner 1, further helping to evenly distribute more hot air in the inner liner 1.

[0104] To maintain the overall consistency of the protective cover body and enhance its aesthetic appeal, a plurality of first air outlet holes 5102 are provided on the first left side wall 514, the first lower side wall 512, and the first upper side wall 511, away from the second sub-cavity 52. ​​No first air outlet holes 5102 are provided on the first right side wall 513. The first air outlet holes 5102 and the fifth air outlet holes 5207 are symmetrically arranged about the first partition 55.

[0105] like Figure 9 and Figure 10 As shown, a plurality of sixth air outlet holes 5208 are further provided on the second end wall 525. The sixth air outlet holes 5208 are located outside the air outlet area and away from the first sub-cavity 51. For example, the sixth air outlet holes 5208 can be located at the upper right corner of the second end wall 525, or at the lower right corner.

[0106] The sixth air outlet 5208 further allows more hot air to be discharged through the sixth air outlet 5208. Since the sixth air outlet 5208 is located away from the first sub-cavity 51, the hot air can gradually diffuse from the right area to the left area of ​​the inner liner 1, further helping to evenly distribute more hot air in the inner liner 1.

[0107] To maintain the overall consistency of the protective cover body and enhance its overall aesthetics, the first end wall 515 is further provided with a plurality of second air outlets 5103. These second air outlets 5103 are located outside the air inlet area and away from the second sub-cavity 52. ​​For example, the second air outlets 5103 may be located at the upper left corner or the lower left corner of the first end wall 515.

[0108] The arrangement of the multiple sixth air outlet holes 5208 on the second end wall 525 is the same as the arrangement of the multiple second air outlet holes 5103 on the first end wall 515, and the sixth air outlet holes 5208 on the second end wall 525 and the second air outlet holes 5103 on the first end wall 515 are symmetrically arranged about the first partition 55.

[0109] As an implementable manner, a closed area is provided on the end wall of the protective cover body between the air inlet area and the air outlet area, and no air outlet holes are provided in the closed area.

[0110] At least Figures 8-10 As shown, the end walls of the protective cover body include a first end wall 515 having an air inlet area and a second end wall 525 having an air outlet area. The first partition 55 and the area between the first end wall 515 and the second end wall 525 are spaced apart and arranged parallel to each other to form the aforementioned air duct. The air duct is configured as a closed area. This prevents hot air from being discharged through the first partition 55 or the area between the air inlet and air outlet areas of the protective cover body when hot air in the first sub-cavity 51 passes through the air duct to the second sub-cavity 52. ​​This helps more hot air enter the second sub-cavity 52, and thus more hot air can enter the inner liner 1, improving the drying effect of the hot air in the inner liner 1.

[0111] In detail, such as Figure 11 、 Figure 15 As shown, one hot air device is located in the first sub-cavity 51 and the other hot air device is located in the second sub-cavity 52 for illustration:

[0112] The protective cover body includes a side wall and an end wall, and the side wall is arranged around the edge of the end wall to form a cavity 501.

[0113] like Figure 13-15 As shown, the second partition 56 is disposed in the cavity 501 , and the second partition 56 divides the cavity 501 into a first sub-cavity 51 and a second sub-cavity 52 that are independent of each other.

[0114] Since the first sub-cavity 51 and the second sub-cavity 52 are independent of each other, the mutual influence between the two hot air devices can be suppressed.

[0115] In addition, the second partition 56 is in contact with the end wall and side wall of the cavity 501, and the second partition 56 has abutting effect on the end wall and side wall of the cavity 501, which can improve the overall strength and rigidity of the protective cover body, and avoid the deformation of the first sub-cavity 51 and the second sub-cavity 52 due to the deformation of the protective cover body, which makes it impossible to install the protective cover on the rear cavity plate of the cleaning machine, or avoid the blades of the fan 2 from scratching against the cavity wall of the first sub-cavity 51 when rotating, or avoid the blades of the fan 2 from scratching against the cavity wall of the second sub-cavity 52 when rotating.

[0116] Among them, at least Figure 11 、 Figure 12 、 Figure 14 、 Figure 15 As shown, the second partition 56 is long and is located in the middle position of the cavity 501 in the left-right direction. The length of the second partition 56 extends along the up-down direction of the cavity 501 until the upper end of the second partition 56 fits seamlessly with the upper side wall of the cavity 501; the lower end of the second partition 56 fits seamlessly with the upper side wall of the cavity 501, and the second partition 56 fits seamlessly with the end wall of the cavity 501.

[0117] like Figure 14 and Figure 15 As shown, the end wall region located on the left side of the second partition 56 is the first end wall 515 ; the end wall region of the cavity 501 located on the right side of the second partition 56 is the second end wall 525 .

[0118] 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 .

[0119] 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 second partition 56 share the first right side wall 513.

[0120] 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 second partition 56 share the second left side wall 524.

[0121] Among them, such as Figure 13-15 As shown, a second groove 561 is provided on the second partition 56 , and the length extension direction of the second groove 561 is the same as the length extension direction of the avoidance groove 54 .

[0122] like Figure 12 、 Figure 13 As shown, the water pipe 4 is arranged vertically and located on the rear cavity plate 11 of the inner tank 1. The water pipe 4 passes through the avoidance groove 54 and the second groove 561 of the second partition 56, allowing the water pipe 4 to supply water to the upper spray arm and other components, thereby ensuring that the installation of the protective cover 5 and the water pipe 4 do not affect each other. Furthermore, the second partition 56 also protects the water pipe 4 by preventing hot air from coming into contact with the water pipe 4, suppressing the hot air's impact on the water pipe 4 and helping to extend the service life of the water pipe 4.

[0123] As an implementation method, a first air inlet area is provided on the first end wall 515 of the first sub-cavity 51, and a first air inlet hole 5101 is provided in the first air inlet area. A plurality of first side walls are provided around the first end wall 515, and at least one of the plurality of first side walls has a first air outlet hole 5102, and one of the first side walls is away from the second sub-cavity 52.

[0124] A second air inlet area is provided on the second end wall 525 of the second sub-cavity 52, and a second air inlet hole 52062 is provided in the second air inlet area. A plurality of second side walls are provided around the second end wall 525, and a fifth air outlet hole 5207 is provided on at least one of the plurality of second side walls, and one of the plurality of second side walls is away from the first sub-cavity 51.

[0125] Specifically, if Figure 14 and Figure 15 As shown, a first air inlet area is provided on the first end wall 515, and the first air inlet area is provided with a plurality of first air inlet holes 5101. The first 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 circular array or a rectangular array.

[0126] Since the first left side wall 514, the first lower side wall 512 and the first upper side wall 511 are arranged away from the second sub-cavity 52, multiple first air outlet holes 5102 are respectively provided on the first left side wall 514, the first lower side wall 512 and the first upper side wall 511, while the first right side wall 513 is arranged close to the second sub-cavity 52, and no first air outlet holes 5102 are provided on the first right side wall 513.

[0127] like Figure 11-13 As shown, the fan 2 rotates, causing the air in the inner liner 1 to enter the first sub-cavity 51 from the front of the first sub-cavity 51 (or, the first air inlet 5101). The heating tube 6 surrounding the fan 2 heats the air, and the hot air is discharged into the inner liner 1 from the side of the first sub-cavity 51 (or, the first air outlet 5102). This forms a first internal circulation air duct, preventing steam overflow.

[0128] Similarly, if Figure 14 and Figure 15 As shown, a second air inlet area is provided on the second end wall 525, and a plurality of second air inlet holes 52062 are provided in the second air inlet area. The second 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 second air inlet holes 52062 can be arranged in a circular array or a rectangular array.

[0129] Because the second lower sidewall 522, the second right sidewall 523, and the second upper sidewall 521 are all located away from the first sub-cavity 51, a plurality of fifth air outlet holes 5207 are provided on each of the second lower sidewall 522, the second right sidewall 523, and the second upper sidewall 521. However, the second left sidewall 524 is located closer to the first sub-cavity 51 and does not have any fifth air outlet holes 5207.

[0130] like Figure 11-13 As shown, the fan 2 rotates, causing the air in the inner liner 1 to enter the second sub-cavity 52 from the front of the second sub-cavity 52 (or, the second air inlet 52062). The heating tube 6 surrounding the fan 2 heats the air, and the hot air is discharged into the inner liner 1 from the side of the second sub-cavity 52 (or, the fifth air outlet 5207). This forms a first internal circulation air duct, preventing steam overflow.

[0131] In addition, since the second lower side wall 522, the second right side wall 523 and the second upper side wall 521 are all arranged away from the first sub-cavity 51; since the first left side wall 514, the first lower side wall 512 and the first upper side wall 511 are arranged away from the second sub-cavity 52, the mutual influence between the first internal circulation air duct and the second internal circulation air duct is suppressed.

[0132] As an achievable method, Figure 14 and Figure 15 As shown, on the first end wall 515, the first air inlet area is offset toward the first side wall where the first air outlet 5102 is provided; or / and,

[0133] On the second end wall 525, the second air inlet area is offset toward the second side wall where the fifth air outlet 5207 is provided, so as to help suppress the mutual influence between the first internal circulation air duct and the second internal circulation air duct.

[0134] As an achievable method, Figure 14 and Figure 15 As shown, a plurality of second air outlet holes 5103 are provided on the first end wall 515 on the side of the first air inlet area away from the second partition 56, and the second air outlet holes 5103 are close to the corner of the first end wall 515; or / and, a plurality of sixth air outlet holes 5208 are provided on the second end wall 525 on the side of the second air inlet area away from the second partition 56, and the sixth air outlet holes 5208 are close to the corner of the second end wall 525.

[0135] Since the second air outlet 5103 is arranged away from the second sub-cavity 52 and the sixth air outlet 5208 is arranged away from the first sub-cavity 51, it helps to suppress the mutual influence between the first internal circulation air duct and the second internal circulation air duct.

[0136] As an achievable method, Figure 14and Figure 15 As shown, a plurality of third air outlet holes 5104 are provided in the area of ​​the first end wall 515 close to the second partition 56 . The plurality of third air outlet holes 5104 are arranged in the up-down direction and can be arranged at equal intervals.

[0137] A plurality of seventh air outlet holes 5209 are provided in an area of ​​the second end wall 525 close to the second partition 56 . The plurality of seventh air outlet holes 5209 are arranged in the up-down direction and may be arranged at equal intervals.

[0138] like Figure 13 As shown, since the hot air discharged through the third air outlet 5104 and the seventh air outlet 5209 moves forward, and the third air outlet 5104 and the seventh air outlet 5209 are separated by the second partition 56, it helps to suppress the mutual influence between the first internal circulation air duct and the second internal circulation air duct.

[0139] As an achievable method, Figure 14 and Figure 15 As shown, the total area of ​​the third air outlet 5104, the second air outlet 5103, and the first air outlet 5102 is less than or equal to the total area of ​​the first air inlet 5101. This allows the hot air discharged from the air outlet to have a higher wind pressure and a faster flow rate, allowing the hot air to flow more fully in the inner liner 1.

[0140] As an achievable method, Figure 14 and Figure 15 As shown, the total area of ​​the seventh air outlet 5209, the sixth air outlet 5208, and the fifth air outlet 5207 is less than or equal to the total area of ​​the second air inlet 52062. 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.

[0141] It should be noted that, in the above embodiment, a hot air device may also be located in the first sub-cavity 51, such as Figure 16-17 As shown, only one fan 2 is located in the second sub-cavity 52 .

[0142] 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.
