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 set on one side of the inner tank. The offset setting of the drying device causes the temperature distribution of the air blown into the inner tank to be uneven. If the detected air temperature in the inner tank is too low, the operating time of the drying device will be extended, energy consumption will increase, and it will be unfavorable for the control of the air temperature in the inner tank. It is impossible to ensure that the maximum temperature in the inner tank is still within the controllable range. Utility Model Content

[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 1-8 As shown, the present invention provides a cleaning machine, comprising:

[0047] An inner container 1, comprising a rear wall panel 11, 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;

[0048] An air supply system is installed on the rear wall panel 11 and is located in the inner tank 1. The air supply system has an air inlet 56 and an air outlet 57. Along the flow direction of the fluid, the air outlet 57 is located downstream of the air inlet 56.

[0049] The air outlet 57 is arranged adjacent to the first side wall panel 12 or the second side wall panel 13 so as to be offset relative to the rear wall panel 11;

[0050] The cleaning machine further includes a temperature sensor 6 for detecting the temperature in the inner tank 1 . The temperature sensor 6 is disposed in the inner tank 1 and on the same side as the air outlet 57 .

[0051] 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 and other items such as bowls, cutlery, and dishes. 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.

[0052] Among them, the inner tank 1 is the main body of the cleaning machine, which is mainly used to accommodate and place kitchen utensils or other items to be cleaned. It can be made of, but not limited to, stainless steel and formed by sheet metal processing or stamping technology. Figure 1 As shown, 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.

[0053] An air supply system is provided on one side of the rear wall panel 11 located within the inner container 1. The air supply system comprises an air inlet 56 and an air outlet 57. The air outlet 57 is provided adjacent to the first side wall panel 12 or the second side wall panel 13 and is offset relative to the rear wall panel 11, facilitating air intake from the front of the protective cover 5 and air outlet from the side, thereby forming an internal circulation duct for air flow. 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 duct, accelerating air flow without causing steam overflow. The air supply device can deliver dry air into the inner container 1 to dry the kitchen utensils in the inner container 1, thereby improving the disinfection and sterilization level of the kitchen utensils.

[0054] The temperature sensor 6 can detect the temperature change in the inner container 1 so as to achieve the best drying effect. The temperature sensor 6 is arranged in the inner container 1 and on the same side as the air outlet 57. For example, Figure 1 and Figure 2 As shown, if the air outlet 57 is arranged adjacent to the first side wall plate 12, the temperature sensor 6 is arranged on the first side wall plate 12; for another example, if the air outlet 57 is arranged adjacent to the second side wall plate 13, the temperature sensor 6 is arranged on the second side wall plate 13. This arrangement allows the temperature sensor 6 to be close to the position of the air outlet 57, and the dry air blown out of the air outlet 57 can be directly collected by the temperature sensor 6 to obtain a temperature value. The temperature value at this position is a position where the temperature value distribution of the air in the inner tank 1 is relatively high. By monitoring the temperature value at this position, it can be ensured that the highest temperature in the inner cavity is still within the preset temperature range, and the kitchen utensils in the inner tank 1 can be dried more accurately, thereby achieving the best disinfection and sterilization effect. The preset temperature can be set according to actual needs and is not specifically limited in this application.

[0055] It should be noted that when the temperature sensor 6 is arranged on the first side wall plate 12 or the second side wall, it is arranged on the side of the first side wall plate 12 or the second side wall close to the rear wall plate 11, so that the temperature sensor 6 is closer to the air outlet 57, so that the temperature sensor 6 can directly collect the temperature value of the air blown out of the air outlet 57. The temperature value at this position is the position where the temperature value distribution of the air in the inner tank 1 is the highest; and the temperature sensor 6 is close to the rear side of the first side wall plate 12 or the second side wall plate 13, and will not be affected by the kitchen utensils placed on the shelf 7 in the inner tank 1, resulting in the dry air blown into the inner tank 1 from the air outlet 57 being blocked, resulting in the problem of inaccurate temperature recognition, thereby improving the accuracy of temperature detection in the inner tank 1.

[0056] The cleaning machine provided in the embodiment of the present application, by arranging the relative positions of the temperature sensor 6 and the air outlet 57, can ensure that the maximum temperature within the inner liner 1 remains within a set controllable range, thereby improving the accuracy of temperature control within the inner liner 1, without extending the operating time of the air supply system, and reducing energy consumption. Furthermore, the air outlet 57 is offset relative to the rear wall panel 11, and the temperature sensor 6 is arranged on the same side as the air outlet 57, so that the temperature sensor 6 is positioned near the rear side of the first side wall panel 12 or the second side wall panel 13. This can prevent interference with temperature testing from factors within the inner liner 1, such as the shelf 7, and improve the accuracy of temperature recognition within the inner liner 1.

[0057] As an achievable method, Figure 2 、 Figure 4 、 Figure 8As shown, 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 air outlet 57 is opened on the corresponding side wall of the protective cover 5, and the hot air device is arranged in the protective cover 5.

[0058] Specifically, such as Figure 7 and Figure 9 As shown, 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 connected to the rear wall plate 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. The hot air device can heat the dry air sucked in by the air inlet 56 to form hot air. The hot air is sent into the inner container 1 through the air outlet 57, quickly raising the temperature inside the inner container 1 to dry the kitchen utensils in the inner container 1, improving the disinfection and sterilization level, and meeting the user's needs for disinfection and storage of kitchen utensils.

[0059] Among them, such as Figure 6 As shown, the hot air device includes a fan 2 and a heating tube 3. The fan 2 is fixed to the rear wall plate 11. The fan 2 has an impeller located inside the inner tank 1 and a driving unit such as a motor located outside the inner tank 1. The output shaft of the driving unit passes through the rear wall plate 11 and is fixedly connected to the impeller. The impeller is arranged to rotate about its own axis, and the rotation axis of the impeller extends forward and backward. The heating tube 3 includes a heating section, which is an open ring. The heating section is provided with a connecting section at least at one end. The connecting section is fixedly provided on the rear wall plate 11. The impeller is located in the open ring. The air in the cavity 501 is centrifugally thrown out by the impeller 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 tank 1 to quickly increase the temperature inside the inner tank 1.

[0060] For example, Figure 6 、 Figure 7 and Figure 9As shown, the side walls of the protective cover 5 include a first left side wall 514 , a first lower side wall 512 , a first right side wall 513 , a first upper side wall 511 , a second left side wall 524 , a second lower side wall 522 , a second right side wall 523 and a second upper side wall 521 . Among them, at least one side wall of the first left side wall 514 and the second right side wall 523 is arranged adjacent to the first side wall plate 12 or the second side wall plate 13. If the first left side wall 514 is arranged adjacent to the first side wall plate 12, the air outlet 57 is arranged on the first left side wall 514, and the temperature sensor 6 is arranged on the first side wall plate 12; or, the second right side wall 523 is arranged adjacent to the second side wall plate 13, the air outlet 57 is arranged on the second right side wall 523, and the temperature sensor 6 is arranged on the second side wall plate 13; or, the first left side wall 514 is arranged adjacent to the first side wall plate 12, and the second right side wall 523 is arranged adjacent to the second side wall plate 13, the air outlet 57 is arranged on the first side wall plate 12 or / and the second side wall plate 13, and the temperature sensor 6 is arranged on the same side as the air outlet 57.

[0061] In this example, the setting position of the temperature sensor 6 is determined according to the opening position of the air outlet 57 on the side wall of the protective cover 5, so that the temperature sensor 6 is set close to the air outlet 57. The temperature of the dry air blown out of the air outlet 57 can be measured by the temperature sensor 6 in the first time, ensuring that the maximum temperature in the inner tank 1 is within the set controllable range.

[0062] Further, such as Figures 4 to 9 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 .

[0063] 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, and the air outlet 57 is close to the hot air device, so that the temperature of the hot air blown into the inner tank 1 by the air outlet 57 is closer to the temperature of the hot air formed by heating of the hot air device, so that the temperature sensor 6 can timely detect the temperature of the hot air formed by the hot air device, and thus can accurately control the temperature inside the inner tank 1.

[0064] In this example, the real-time temperature inside the inner tank 1 is detected by the temperature sensor 6, and the hot air device controls its own operating time according to the real-time temperature detected by the temperature sensor 6, so that the maximum temperature inside the inner tank 1 is always within the preset temperature range, so as to achieve the best drying effect for the kitchen utensils, meet the disinfection and sterilization requirements of the kitchen utensils, and save the energy consumption of the hot air device.

[0065] As an achievable method, Figure 3 As shown, a through hole for the temperature sensor 6 to pass through is opened on one side of the first side wall plate 12 close to the rear wall plate 11 . The temperature sensor 6 passes through the through hole and is fixed on the first side wall plate 12 .

[0066] Exemplarily, an air outlet 57 is provided on the first left side wall 514 of the protective cover 5. The temperature sensor 6 is fixed to the first side wall panel 12 via a through hole provided at the rear of the first side wall panel 12. The probe of the temperature sensor 6 is positioned slightly above the air outlet 57. Since the hot air generated after being heated by the heating tube 3 rises, and the driving action of the fan 2 is combined, the amount of hot air flowing upward is greater than the amount of hot air flowing downward. Therefore, the air temperature slightly above the air outlet 57 is higher than the air temperature slightly below the air outlet 57. The temperature sensor 6 is positioned slightly above the air outlet 57. The air temperature at this position is the highest point in the air temperature distribution within the inner container 1. By monitoring the temperature value at this position, it is possible to ensure that the highest temperature in the inner cavity remains within the preset temperature range, and the kitchen utensils in the inner container 1 can be more accurately controlled, thereby achieving the best disinfection and sterilization effect.

[0067] Further, such as Figure 3 As shown, the temperature sensor 6 has a laterally extending limiting rib 61 at a position adjacent to one of its two ends, and a locking piece 62 is also provided on the temperature sensor 6. When the temperature sensor 6 is installed in the through hole, the locking piece 62 and the rib 61 respectively abut against the inner and outer sides of the first side wall plate 12.

[0068] Specifically, one end of the temperature sensor 6 extending into the inner tank 1 has a laterally extending limiting rib 61, the cross-sectional area of ​​the limiting rib 61 is larger than the area of ​​the through hole, and the other end is detachably connected to a locking piece 62. The temperature sensor 6 passes through the through hole, and the locking piece 62 and the rib 61 respectively abut against the inner and outer sides of the first side wall to fix the temperature sensor 6 on the first side wall plate 12. The cooperation between the limiting rib 61 and the locking piece 62 facilitates the disassembly, installation and replacement of the temperature sensor 6.

[0069] Furthermore, Figure 3 As shown, the retaining edge 61 is located inside the inner liner 1, and the locking member 62 is located outside the inner liner 1 and can be rotatably constrained on the temperature sensor 6, and can move axially relative to the temperature sensor 6 under the action of its own rotation, and when the locking member 62 is rotated to the outside of the first side wall plate 12 and abuts against it, the locking member 62 and the retaining edge 61 jointly form a limit for the temperature sensor 6 on the first side wall plate 12.

[0070] Exemplarily, the locking member 62 can be a nut having an internal thread, and an external thread is provided at one end of the temperature sensor 6 away from the retaining edge 61. The external thread matches the internal thread, so that the nut and the temperature sensor 6 are detachably connected by a threaded connection. The nut moves axially relative to the temperature sensor 6 under the cooperation of the internal thread and the external thread, and moves to a state where it is in contact with the outer side of the first side wall plate 12. The locking member 62 and the retaining edge 61 form a constraint on the temperature sensor 6, so that the temperature sensor 6 is fixed on the first side wall plate 12.

[0071] As an implementable manner, a seal is provided between the retaining edge 61 and the first side wall plate 12 , and the seal is provided with a through hole for the temperature sensor 6 to pass through. The temperature sensor 6 passes through the through hole and is sealedly connected to the first side wall plate 12 through the seal.

[0072] In this example, the sealing member may be a sealing gasket made of rubber material, and the temperature sensor 6 is fixed to the first side wall plate 12 through the sealing gasket to ensure the sealing inside the inner container 1.

[0073] As an achievable method, Figure 2 As shown, a shelf 7 is provided in the inner container 1 , and the temperature sensor 6 is provided away from the shelf 7 .

[0074] Specifically, the shelf 7 includes, but is not limited to, stainless steel and is used to place kitchen utensils, etc. The temperature sensor 6 is placed away from the shelf 7 to prevent the kitchen utensils placed on the shelf 7 from blocking the hot air supplied to the inner container 1 through the air outlet 57, thereby improving the accuracy of temperature recognition by the temperature sensor 6.

[0075] Further, such as Figure 2 As shown, the rack 7 includes a first rack 71 and a second rack 72, wherein the first rack 71 and the second rack 72 are spaced apart in the upper and lower directions along the height direction of the inner pot 1, and the temperature sensor 6 is arranged between the first rack 71 and the second rack 72 in the height direction of the inner pot 1.

[0076] In this example, the first rack 71 and the second rack 72 are spaced apart vertically along the height of the inner liner 1, improving the utilization of the space within the inner liner 1 and allowing more kitchen utensils, etc. to be placed in the inner liner 1 at one time. The temperature sensor 6 is positioned between the first rack 71 and the second rack 72 along the height of the inner liner 1, improving the accuracy of temperature recognition by the temperature sensor 6. The first rack 71 is positioned above the second rack 72, and the temperature sensor 6 can be positioned toward the first rack 71, placing the temperature sensor 6 closer to the upper portion of the air outlet 57. This further improves the accuracy of temperature recognition and ensures that the air temperature detected by the temperature sensor 6 is the highest temperature in the air temperature distribution within the inner liner 1.

[0077] As an achievable method, Figure 1 and Figure 2 As shown, the cleaning machine further includes a respirator 8 , which is disposed on the same side as the temperature sensor 6 and staggered.

[0078] Specifically, during the cleaning process, the cleaning machine inevitably causes changes in the air pressure within the inner liner 1. The provision of the respirator 8 ensures air pressure balance within the inner liner 1. The temperature sensor 6 and the respirator 8 are staggered and located on the same side to prevent interference with the temperature sensor 6 and improve the accuracy of the temperature sensor 6's temperature recognition. Exemplarily, the temperature sensor 6 and the respirator 8 are located on the second sidewall 13, with the respirator 8 located below the temperature sensor 6.

[0079] As an implementable method, the protective cover 5 has a cavity 501, and the cavity 501 includes a first sub-cavity 51 and a second sub-cavity 52 arranged side by side laterally along the rear wall plate 11, and the hot air device is arranged in at least one of the first sub-cavity 51 and the second sub-cavity 52.

[0080] In some embodiments, as Figure 4-7 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.

[0081] 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.

[0082] In other embodiments, Figures 8 to 10 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.

[0083] 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.

[0084] 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.

[0085] 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. The second sub-cavity 52 may be provided with another hot air device; or, the second sub-cavity 52 may be provided with only one fan 2; or, the second sub-cavity 52 may be provided with an ultraviolet lamp; or, the second sub-cavity 52 may be provided with no mechanism, and the cavity 501 structure may be used.

[0086] 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.

[0087] For example, Figures 1 to 7 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:

[0088] At least Figure 7 As shown, the protective cover 7 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. The first side and the second side are arranged opposite to each other.

[0089] 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.

[0090] like Figure 7As 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.

[0091] 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.

[0092] 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 .

[0093] like Figure 7 and Figure 9 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.

[0094] 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.

[0095] It is understood that the air outlet 57 can be provided on the first left side wall 514 and / or the second right side wall 523. In addition, the air outlet 57 can also be provided on at least one of the first lower side wall 512, the first upper side wall 511, the second lower side wall 522, and the second upper side wall 521. The corresponding temperature sensor 6 is provided on the first side wall panel 12 and / or the second side wall panel 13, and is provided on the first side wall panel 12 and / or the second side wall panel 13, and is provided on a side of the first side wall panel 12 and / or the second side wall panel close to the rear wall panel 11.

[0096] 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.

[0097] The protective cover 5 can be made of, but is not limited to, stainless steel.

[0098] The protective cover 5 can be made of, but is not limited to, a sheet metal process or a stamping process.

[0099] 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.

[0100] In addition, if Figure 1 、 Figure 4 、 Figure 5 and Figure 8 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.
