Abstract
Description
Technical Field
[0001] This application belongs to the field of cleaning technology, and more specifically, relates to a machine cover and a cleaning machine. Background Technology
[0002] Cleaning machines use cleaning solutions to clean tableware, drinking containers (such as water cups and baby bottles), and high-temperature steam to disinfect the items. After cleaning, the items will adhere to the cleaning solution and the condensation formed by the steam. Bacteria can easily grow on the items after they adhere to the cleaning solution and condensation.
[0003] In related technologies, washing machines use heated air to dry the items to be washed, thereby removing the cleaning solution. However, after the washing machine heats the items, the temperature of the outer surface of the machine casing rises, which can easily cause burns to users who touch it, affecting the user experience. Summary of the Invention
[0004] The purpose of this application is to provide a machine cover and a cleaning machine to improve the user experience of the cleaning machine.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, a cover for a cleaning machine is provided. The cleaning machine includes a body, and the cover is adapted to be connected to the body and to enclose the body to form a cleaning chamber. The cover includes a top plate and a side plate, the side plate being disposed on the side of the top plate facing the cleaning chamber, and at least one of the top plate and the side plate having a cavity inside.
[0007] With the above technical solution, when the cleaning machine uses heated air to heat the items to be cleaned, the cavity helps to prevent the high-temperature gas in the cleaning chamber from transferring heat to the outer surface of the machine cover, which helps to reduce the temperature of the outer surface of the machine cover, thereby helping to avoid scalding the user and improving the user experience of the cleaning machine.
[0008] Therefore, the hood provided in this application can improve the user experience of the cleaning machine.
[0009] In some embodiments, at least one of the top plate and the side plate includes an outer sub-plate and an inner sub-plate, with a cavity formed between the outer sub-plate and the inner sub-plate, and the thermal conductivity of the outer sub-plate being less than that of the inner sub-plate.
[0010] In this way, the high-temperature gas in the cleaning chamber is less likely to transfer heat to the outer surface of the shroud, which helps to reduce the temperature of the outer surface of the shroud.
[0011] In some embodiments, the outer sub-sheet is made of polypropylene, and / or the inner sub-sheet is made of ABS plastic.
[0012] This design, combined with the low thermal conductivity of polypropylene, helps to prevent heat transfer to the outer surface of the casing. Furthermore, ABS plastic is highly safe, being a food-grade plastic material that can come into direct contact with food, thus enhancing safety.
[0013] In some embodiments, at least one of the top plate and the side plate is provided with an air inlet and an air outlet communicating with the cavity, the air inlet being used to introduce cold air into the cavity.
[0014] In this way, cold air can enter the cavity through the air inlet, which is beneficial for cooling the shroud. After entering the cavity, the cold air can be discharged through the air outlet, allowing the cold air to circulate within the cavity and improving the cooling effect.
[0015] In some implementations, the air inlet is located on the outer sub-plate, and the air outlet is located on the inner sub-plate.
[0016] This design facilitates the entry of cold air into the air intake and helps prevent hot air generated after the cold air enters the cavity for heat exchange from being discharged outside the casing, thus preventing burns to users.
[0017] In some embodiments, the side plate has a cavity and at least one vent hole, the at least one vent hole being located at one end of the inner sub-plate near the top plate, and the extending direction of the at least one vent hole being parallel to the top plate.
[0018] In this way, after the cold air cools the hood, it can be discharged from the air outlet in a direction parallel to the top plate, forming an "air knife." This effectively blows the condensate on the surface of the top plate facing the cleaning chamber to the edge of the top plate, preventing condensate from dripping onto the items to be cleaned. The "air knife" refers to the high velocity and force of the air discharged from the air outlet in a direction parallel to the top plate, which easily blows the condensate on the surface of the top plate facing the cleaning chamber to the edge of the top plate, simulating the action of a blade scraping condensate to the edge of the top plate.
[0019] In some embodiments, a portion of the wall of at least one vent is disposed on the side surface of the top plate facing the cleaning chamber.
[0020] In this way, the air blown out from at least one vent can directly contact the surface of the top plate facing the cleaning chamber and flow in a direction parallel to the bottom plate, which is beneficial for blowing the condensate on the surface of the top plate facing the cleaning chamber to the edge of the top plate.
[0021] In some embodiments, a chamfer is provided at the junction of the wall of the vent and the wall of the cavity.
[0022] This facilitates the air in the cavity to be discharged from the vent, helps to avoid the sharp edges at the junction of the vent wall and the cavity wall from blocking the air, and helps to increase the air flow rate.
[0023] In some embodiments, the side plate is provided with multiple air vents, which are spaced apart in a direction perpendicular to the top plate. The air vent closest to the top plate is the first air vent, and the extension direction of the first air vent is parallel to the top plate.
[0024] In this way, the air discharged from the first vent can directly contact the surface of the top plate facing the cleaning chamber and flow in a direction parallel to the bottom plate, which helps to blow the condensate on the surface of the top plate facing the cleaning chamber to the edge of the top plate.
[0025] In some embodiments, the vent located on the side of the first vent away from the top plate is the second vent, and the end of the second vent away from the cavity is inclined in the direction close to the top plate.
[0026] In this way, the air discharged from the second vent can also be blown toward the top plate, which helps to increase the amount of air blowing onto the top plate, thereby helping to blow the condensate on the surface of the top plate facing the cleaning chamber to the edge of the top plate.
[0027] In some embodiments, the cavity includes a plurality of first flow channels arranged in parallel, the first flow channels extending in a direction perpendicular to the top plate, and at least a portion of the cross-sectional area of the first flow channels gradually decreasing in the direction close to the top plate, the cross-section being parallel to the top plate.
[0028] In this way, the air can increase its flow rate after passing through the first guide channel, thereby increasing the flow rate of the air discharged from the air outlet, which in turn helps to blow the condensate on the surface of the top plate facing the cleaning chamber to the edge of the top plate.
[0029] In some embodiments, the partition plate is disposed within the cavity, positioned between two adjacent first flow channels, and integrally formed with the outer layer plate. This facilitates the formation of the first flow channels and is advantageous for manufacturing the outer layer plate and the partition plate.
[0030] In some embodiments, a guide portion is provided on the side of the inner sub-plate away from the cavity, the guide portion is arranged around the air outlet and extends along the extension direction of the air outlet.
[0031] In this way, the air discharged from the vent can continue to flow along the extension direction of the vent, which helps to reduce the degree of dispersion of the air discharged from the vent, thereby improving the degree of convergence of the air discharged from the vent, which can increase the wind force and improve the force on the condensate.
[0032] In some embodiments, the side panel also includes a water collection trough, which is disposed at the lower end of the inner sub-panel and on the side of the inner sub-panel away from the cavity, with an opening at the upper end of the water collection trough.
[0033] In this way, the condensate is blown to the edge of the top plate and can flow along the inner surface of the side plate into the water collection tank, thus preventing the condensate from splashing onto the items to be cleaned.
[0034] In some embodiments, the shroud also includes a plurality of guide plates spaced apart along a first direction. The plurality of guide plates are disposed on the side surface of the top plate facing the cleaning chamber and are disposed near the air outlet. A second guide channel is formed between two adjacent guide plates. The extension direction of the second guide channel is consistent with the extension direction of the air outlet. The first direction is perpendicular to the extension direction of the air outlet and parallel to the top plate.
[0035] In this way, the air discharged from the vent can flow along the second guide channel, which helps to prevent the air from diffusing to the outside, increases the wind force, and thus helps to blow the condensate to the edge of the top plate.
[0036] In some embodiments, at least a portion of the deflector is arc-shaped, and the center of arc of at least a portion of the deflector is located on the side of the deflector toward the edge of the top plate along a first direction.
[0037] In this way, the air discharged from the vent can gradually diffuse along the first direction, blowing the condensate to the edge of the top plate along the first direction. This allows the condensate to be evenly distributed, which helps to prevent excessive condensate from accumulating and dripping onto the items to be cleaned as it moves towards the edge of the top plate.
[0038] Secondly, this application provides a cleaning machine, which includes:
[0039] In any of the above embodiments, at least one of the top plate and the side plate of the hood is provided with an air inlet and an air outlet communicating with the cavity, and the air inlet is used to introduce cold air into the cavity.
[0040] The machine body and the machine cover are connected to the machine body and enclose each other to form a cleaning chamber;
[0041] An air supply assembly is installed in the body and includes a fan, a distribution pipe, and a heater. The distribution pipe includes a hot air channel and a cold air channel that are not interconnected. The heater is installed in the hot air channel. Both the hot air channel and the cold air channel are connected to the air outlet of the fan. The hot air channel is connected to the cleaning chamber, and the cold air channel is used to connect to the air inlet.
[0042] In this way, the air supply assembly can introduce cold air into the cavity, thereby cooling the hood. Furthermore, the cleaning machine provided in this application has the same technical effects as the hood in any of the above embodiments, and will not be repeated here.
[0043] In some embodiments, the cleaning machine provided in this application further includes a controller and an air inlet valve. A cold air duct is used to communicate with an air inlet via the air inlet valve. The controller is electrically connected to the fan, heater, and air inlet valve. The controller is configured to:
[0044] Control the operation of the fan and heater;
[0045] After the fan and heater have been operating for a first preset time, the air intake valve is opened to connect the cold air passage with the air intake hole.
[0046] After the intake valve has been open for a second preset time, the control fan, heater, and intake valve are closed.
[0047] In this way, the cleaning machine provided in this application can dry the items to be cleaned, and can also cool the machine cover before the drying is finished.
[0048] In some implementations, the first preset time is longer than the second preset time. This helps to ensure the drying effect. Attached Figure Description

[0069] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0070] The 1000 cleaning machine uses cleaning fluid to clean tableware, drinking containers (such as water cups and baby bottles) and sterilizes the items after using high-temperature steam. The items will adhere to the cleaning fluid and condensate formed by the steam, which can easily breed bacteria.
[0071] In related technologies, the washing machine 1000 uses heated air to heat and dry the items to be washed, thereby removing the cleaning liquid from the items. However, after the washing machine 1000 heats the items to be washed, the temperature of the outer surface of the machine cover 100 rises, and users are easily burned if they touch the outer surface of the machine cover 100, affecting the user experience.
[0072] To solve the above-mentioned technical problems, this application provides a machine cover 100 and a cleaning machine 1000.
[0073] Please see Figure 1 This application provides a cleaning machine 1000, which includes a body (not shown in the figure), on which cleaning components 200, washing pump (not shown in the figure), sewage pump and other components (not shown in the figure) can be installed.
[0074] Please refer to the following: Figure 1 and Figure 2 The cleaning machine 1000 provided in this application embodiment also includes a cover 100, which is used to connect to the machine body and to enclose the machine body to form a cleaning chamber. A cleaning assembly 200 can be disposed in the cleaning chamber, and items to be cleaned can be placed on the cleaning assembly 200. A washing pump can deliver cleaning fluid to the cleaning assembly 200, and the cleaning assembly 200 can clean the items placed in the cleaning chamber. The cleaning fluid after cleaning can be discharged by a drain pump.
[0075] Please refer to the following: Figure 2 , Figure 3 and Figure 4 The machine cover 100 includes a top plate 10 and a side plate 20. The side plate 20 is disposed on the side of the top plate 10 facing the cleaning chamber. At least one of the top plate 10 and the side plate 20 has a cavity 103 inside.
[0076] For example, please refer to Figure 3 The top plate 10 has a cavity 103 inside, wherein the cavity 103 inside the top plate 10 can be a first cavity 1031.
[0077] For example, please refer to Figure 4 The side plate 20 has a cavity 103 inside, wherein the cavity 103 inside the side plate 20 can be a second cavity 1032.
[0078] For example, both the top plate 10 and the side plate 20 are provided with cavities 103.
[0079] It is understood that when the cleaning machine 1000 provided in this application uses heated air to heat the items to be cleaned, the cavity 103 helps to prevent the high-temperature gas in the cleaning chamber from transferring heat to the outer surface of the cover 100, which helps to reduce the temperature of the outer surface of the cover 100, thereby helping to avoid scalding the user and improving the user experience of the cleaning machine 1000.
[0080] Therefore, the hood 100 provided in this application embodiment can improve the user experience of the cleaning machine 1000.
[0081] Please continue reading. Figure 3 and Figure 4 In some embodiments, at least one of the top plate 10 and the side plate 20 includes an outer sub-plate 101 and an inner sub-plate 102, and a cavity 103 is formed between the outer sub-plate 101 and the inner sub-plate 102. The thermal conductivity of the outer sub-plate 101 is less than that of the inner sub-plate 102.
[0082] For example, the top plate 10 includes an outer sub-plate 101 and an inner sub-plate 102. The outer sub-plate 101 of the top plate 10 can be a first outer sub-plate 1011, and the inner sub-plate 102 of the top plate 10 can be a first inner sub-plate 1021. The first cavity 1031 of the top plate 10 is formed between the first outer sub-plate 1011 and the first inner sub-plate 1021.
[0083] For example, the side panel 20 includes an outer sub-panel 101 and an inner sub-panel 102. The outer sub-panel 101 of the side panel 20 can be a second outer sub-panel 1012, and the inner sub-panel 102 of the side panel 20 can be a second inner sub-panel 1022. The second cavity 1032 of the side panel 20 is formed between the second outer sub-panel 1012 and the second inner sub-panel 1022.
[0084] It is understandable that the thermal conductivity of the outer sub-plate 101 is less than that of the inner sub-plate 102, and the outer surface of the housing 100 is located on the outer sub-plate 101. After the high-temperature gas in the cleaning chamber transfers heat to the inner sub-plate 102, the rate at which the heat is transferred from the inner sub-plate 102 to the outer sub-plate 101 decreases. Therefore, the high-temperature gas in the cleaning chamber does not easily transfer heat to the outer surface of the housing 100, which helps to reduce the temperature of the outer surface of the housing 100.
[0085] Optionally, the thickness of the outer sub-board 101 can be 1.2mm-1.8mm. For example, the thickness of the outer sub-board 101 can be 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, etc.
[0086] Optionally, the thickness of the inner sub-board 102 can be 1mm-1.5mm. For example, the thickness of the inner sub-board 102 can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc.
[0087] Optionally, the thickness of the cavity 103 can be 3mm-4mm. For example, the thickness of the cavity 103 can be 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, etc. The thickness of the cavity 103 can be the spacing between the outer sub-plate 101 and the inner sub-plate 102.
[0088] In some embodiments, the outer sub-sheet 101 is made of polypropylene, and / or the inner sub-sheet 102 is made of ABS plastic. The ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S).
[0089] Optionally, the outer sub-panel 101 may be made of polypropylene.
[0090] Optionally, the material of the inner sub-sheet 102 includes ABS plastic.
[0091] Optionally, the outer sub-sheet 101 is made of polypropylene, and the inner sub-sheet 102 is made of ABS plastic.
[0092] Understandably, polypropylene has a low thermal conductivity, which helps to prevent heat transfer to the outer surface of the casing 100. Furthermore, ABS plastic is highly safe, being a food-grade plastic material that can directly contact food, thus enhancing safety.
[0093] Please refer to section 2. Optionally, at least one of the top plate 10 and the side plate 20 is a transparent plate, that is, at least one of the top plate 10 and the side plate 20 is made of transparent material. This makes it easy to see the cleaning status in the cleaning chamber, and users can directly feel the cleaning situation, which helps to increase user trust and thus improve the user experience.
[0094] For example, the top plate 10 is a transparent plate.
[0095] For example, the side panel 20 is a transparent panel.
[0096] For example, the top panel 10 is a transparent panel, and the side panel 20 is a transparent panel.
[0097] Optionally, the cover 100 provided in this application embodiment also includes a handle 30, which can be disposed on the top plate 10 and / or the side plate 20, thus facilitating the handling of the cover 100. For example, the handle 30 is disposed on the top plate 10. The handle 30 can also be made of a transparent material.
[0098] Please continue reading 2, and combine it with... Figure 5 and Figure 6 In some embodiments, at least one of the top plate 10 and the side plate 20 is provided with an air inlet 104 and an air outlet 105 communicating with the cavity 103. The air inlet 104 is used to introduce cold air into the cavity 103.
[0099] Optionally, the top plate 10 is provided with an air inlet 104 and an air outlet 105. Cold air can enter the first cavity 1031 of the top plate 10 through the air inlet 104, which is beneficial for cooling the top plate 10. After entering the first cavity 1031, the cold air can be discharged through the air outlet 105. The cold air can circulate in the first cavity 1031, which is beneficial for improving the cooling effect of the top plate 10.
[0100] Optionally, the side plate 20 is provided with an air inlet 104 and an air outlet 105. Cold air can enter the second cavity 1032 of the side plate 20 through the air inlet 104, which is beneficial for cooling the side plate 20. After entering the second cavity 1032, the cold air can be discharged through the air outlet 105. The cold air can circulate in the second cavity 1032, which is beneficial for improving the cooling effect of the side plate 20.
[0101] Optionally, the top plate 10 is provided with an air inlet 104 and an air outlet 105, and the side plate 20 is also provided with an air inlet 104 and an air outlet 105. Cold air can enter the cavity 103 through the air inlet 104, which is beneficial for cooling the shroud 100. After entering the cavity 103, the cold air can be discharged through the air outlet 105. The cold air can circulate in the cavity 103, which is beneficial for improving the cooling effect.
[0102] Please continue to refer to section 2. Figure 5 and Figure 6 In some embodiments, the air inlet 104 is disposed on the outer sub-plate 101, and the air outlet 105 is disposed on the inner sub-plate 102. For example, the air inlet 104 of the top plate 10 is disposed on the first outer sub-plate 1011, and the air outlet 105 of the top plate 10 is disposed on the first inner sub-plate 1021. For example, the air inlet 104 of the side plate 20 is disposed on the second outer sub-plate 1012, and the air outlet 105 of the side plate 20 is disposed on the second inner sub-plate 1022.
[0103] In this way, the air inlet 104 of the hood 100 provided in this embodiment is located on the outer sub-plate 101, which facilitates the entry of cold air into the air inlet 104. Furthermore, the air outlet 105 of the hood 100 provided in this embodiment is located on the inner sub-plate 102, which helps to prevent the hot air formed after the cold air enters the cavity 103 for heat exchange from being discharged to the outside of the hood 100, thus helping to prevent burns to the user.
[0104] Please continue to participate. Figure 5 and Figure 6 In some embodiments, the side plate 20 is provided with a cavity 103, and the side plate 20 is provided with at least one vent 105. The at least one vent 105 is disposed at one end of the inner sub-plate 102 near the top plate 10, and the extending direction of the at least one vent 105 is (e.g.) Figure 5 The Y direction in the middle is parallel to the top plate 10.
[0105] Understandably, after the cold air cools the shroud 100, it can be discharged from the air outlet 105 in a direction parallel to the top plate 10, that is, in the Y direction. The discharged cold air can form an "air knife," which helps to blow the condensate on the surface of the top plate 10 facing the cleaning chamber to the edge of the top plate 10, thus preventing the condensate from dripping onto the items to be cleaned. The "air knife" refers to the fact that the air discharged from the air outlet 105 in a direction parallel to the top plate 10 has a large flow rate and wind force, which easily blows the condensate on the surface of the top plate 10 facing the cleaning chamber to the edge of the top plate 10, which can simulate the actual blade scraping the condensate to the edge of the top plate 10.
[0106] Please continue to participate. Figure 5 and Figure 6In some embodiments, at least one vent 105 has a portion of its wall disposed on the side surface of the top plate 10 facing the cleaning chamber.
[0107] In this way, the air blown out from at least one air outlet 105 can directly contact the surface of the top plate 10 facing the cleaning chamber and flow in a direction parallel to the bottom plate, which is beneficial for blowing the condensate on the surface of the top plate 10 facing the cleaning chamber to the edge of the top plate 10.
[0108] Please continue to participate. Figure 5 and Figure 6 In some embodiments, a chamfer is provided at the connection between the wall of the vent 105 and the wall of the cavity 103. This helps to prevent the sharp edges at the connection between the wall of the vent 105 and the wall of the cavity 103 from blocking the air. The chamfer can reduce the resistance to cold air, thereby facilitating the discharge of cold air in the cavity 103 from the vent 105 and improving the airflow rate.
[0109] Optionally, the side plate 20 is provided with a plurality of air vents 105, which are spaced apart in a direction perpendicular to the top plate 10. The one of the plurality of air vents 105 closest to the top plate 10 is the first air vent 1051, and the extension direction of the first air vent 1051 is parallel to the top plate 10.
[0110] In this way, the air discharged from the first vent 1051 can directly contact the surface of the top plate 10 facing the cleaning chamber and flow in a direction parallel to the bottom plate, which is beneficial to blowing the condensate on the surface of the top plate 10 facing the cleaning chamber to the edge of the top plate 10.
[0111] Optionally, the vent 105 located on the side of the first vent 1051 away from the top plate 10 is the second vent 1052, and the end of the second vent 1052 away from the cavity 103 is inclined in the direction close to the top plate 10.
[0112] In this way, the air discharged from the second air outlet 1052 can also be blown toward the top plate 10, which helps to increase the amount of air blowing onto the top plate 10, thereby helping to blow the condensate on the surface of the top plate 10 facing the cleaning chamber to the edge of the top plate 10.
[0113] Please see Figure 7 In some embodiments, the cavity 103 includes a plurality of first flow channels 201 arranged in parallel, the first flow channels 201 being along a direction perpendicular to the top plate 10 (e.g., Figure 5 The first guide channel 201 extends in the Z direction and at least a portion of its cross-sectional area gradually decreases in the direction close to the top plate 10, with the cross-section parallel to the top plate 10.
[0114] In this way, the air can increase its flow rate after passing through the first guide channel 201, which can increase the flow rate of the air discharged from the air outlet 105, thereby increasing the wind force of the cold air, which in turn helps to blow the condensate on the surface of the top plate 10 facing the cleaning chamber to the edge of the top plate 10.
[0115] Optionally, the partition plate 23 is disposed within the cavity 103, located between two adjacent first flow channels 201, and is integrally formed with the outer sub-plate 101. This facilitates the formation of the first flow channels 201 and is advantageous for manufacturing the outer sub-plate 101 and the partition plate 23. The cross-sectional area of the partition plate 23 gradually increases along the Z-direction and towards the top plate 10, thus forming the first flow channels 201. The cross-section of the partition plate 23 is parallel to the top plate 10.
[0116] Please continue reading. Figure 4 In some embodiments, the side plate 20 further includes a water collection trough 21, which is disposed at the lower end of the inner sub-plate 102 and located on the side of the inner sub-plate 102 away from the cavity 103, with an opening at the upper end of the water collection trough 21.
[0117] In this way, the condensate is blown to the edge of the top plate 10 and can flow along the inner surface of the side plate 20 into the water collection tank 21, thereby preventing the condensate from splashing onto the items to be cleaned.
[0118] Optionally, the water collection tank 21 can be provided with a drain outlet, which can be connected to the outside to drain the water in the water collection tank 21. The depth of the water collection tank 21 can be 1.5mm-2.5mm. For example, the depth of the water collection tank 21 can be 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, etc.
[0119] Please continue reading. Figure 6 In some embodiments, a guide portion 22 is provided on the side of the inner sub-plate 102 away from the cavity 103. The guide portion 22 is provided around the air outlet 105 and extends along the extension direction of the air outlet 105.
[0120] In this way, the air discharged from the air outlet 105 can continue to flow along the extension direction of the air outlet 105, which helps to reduce the degree of dispersion of the air discharged from the air outlet 105, thereby improving the degree of convergence of the air discharged from the air outlet 105, which can increase the wind force and improve the force on the condensate.
[0121] Please see Figure 8 In some embodiments, the shroud 100 further includes a plurality of components along a first direction (e.g., Figure 8Multiple guide plates 40 are spaced apart in the X direction of the top plate 10. The guide plates 40 are disposed on the side surface of the top plate 10 facing the cleaning chamber and are close to the air outlet 105. A second guide channel 401 is formed between two adjacent guide plates 40. The extension direction of the second guide channel 401 is consistent with the extension direction of the air outlet 105. The first direction is perpendicular to the extension direction of the air outlet 105 and parallel to the top plate 10.
[0122] In this way, the cold air discharged from the air outlet 105 can flow along the second guide channel 401. The second guide channel 401 can collect the cold air, which is conducive to increasing the wind force and thus helps to blow the condensate to the edge of the top plate 10.
[0123] Optionally, at least a portion of the deflector 40 is arc-shaped, and the center of the arc of at least a portion of the deflector 40 is located on the side of the deflector 40 facing the edge of the top plate 10 along the first direction.
[0124] In this way, the air discharged from the vent 105 can gradually diffuse along the first direction, blowing the condensate water to the edge of the top plate 10 along the first direction, which can make the condensate water evenly dispersed and help avoid excessive accumulation of condensate water as it moves towards the edge of the top plate 10 and dripping onto the items to be cleaned.
[0125] Please continue reading. Figure 1 This application also provides a cleaning machine 1000, which includes the machine cover 100 of any of the above embodiments, and therefore has the same technical effects as any of the above embodiments, which will not be repeated here.
[0126] Please refer to the following: Figure 1 , Figure 9 and Figure 10 The cleaning machine 1000 provided in this application embodiment includes an air supply assembly 300, which is disposed on the machine body and includes a fan 310, a diversion pipe 320 and a heater 330. The diversion pipe 320 includes a hot air channel 3203 and a cold air channel 3202 that are not interconnected. The heater 330 is disposed in the hot air channel 3203. Both the hot air channel 3203 and the cold air channel 3202 are connected to the air outlet of the fan 310. The hot air channel 3203 is connected to the cleaning chamber, and the cold air channel 3202 is used to connect to the air inlet 104.
[0127] Understandably, the air outlet of the fan 310 is connected to the air inlet 3201 of the splitter pipe 320, and both the hot air passage 3203 and the cold air passage 3202 are connected to the air outlet of the fan 310 through the air inlet 3201 of the splitter pipe 320. A portion of the air blown out by the fan 310 enters the hot air passage 3203, where it is heated by the heater 330 and used to dry the items to be cleaned. Then, another portion of the air blown out by the fan 310 enters the cold air passage 3202, which can enter the cavity 103 through the air inlet 104 to cool the casing 100.
[0128] In this way, the air supply assembly 300 can introduce cold air into the cavity 103, thereby cooling the shroud 100.
[0129] Please see Figure 11 After the air supply assembly 300 introduces cold air into the cavity 103, the cold air can pass along the inner surface of the cavity 103 and the shroud 100, covering most of the shroud 100, thus achieving a good cooling effect.
[0130] In some embodiments, the cleaning machine 1000 provided in this application further includes a controller and an air inlet valve (not shown in the figure). The cold air channel 3202 is used to communicate with the air inlet 104 through the air inlet valve. The controller is electrically connected to the fan 310, the heater 330, and the air inlet valve. The controller is configured to:
[0131] Control the operation of fan 310 and heater 330;
[0132] After the fan 310 and heater 330 have been operating for a first preset time, the air intake valve is opened to connect the cold air passage 3202 with the air intake hole 104.
[0133] After the intake valve has been open for a second preset time, the control fan 310, heater 330 and intake valve are closed.
[0134] That is, this application embodiment provides a control method for a cleaning machine 1000, which can be executed by a controller. The control method includes:
[0135] S100 controls the operation of the fan 310 and the heater 330;
[0136] S200: After the fan 310 and heater 330 have been operating for a first preset time, the air intake valve is opened so that the cold air passage 3202 is connected to the air intake hole 104.
[0137] S300 controls the fan 310, heater 330, and intake valve to close after the intake valve has been open for a second preset time.
[0138] In this way, the cleaning machine 1000 provided in this application embodiment can dry the items to be cleaned, and can also cool the machine cover 100 before the drying is finished. Cooling the machine cover 100 in advance helps to reduce the working time of the cleaning machine 1000.
[0139] In some embodiments, the first preset time is longer than the second preset time. This allows the washing machine 1000 sufficient drying time, which helps to ensure the drying effect.
[0140] Please refer to the following: Figures 1 to 10 It should be noted that during the operation of the cleaning machine 1000, the items to be cleaned are first cleaned using the cleaning component 200. The cleaning time is between 10 and 20 minutes, and the temperature of the cleaning solution is between 60°C and 70°C. For example, the cleaning time can be 10 minutes, 11 minutes, 12 minutes, 13 minutes, 14 minutes, 15 minutes, 16 minutes, 17 minutes, 18 minutes, 19 minutes, 20 minutes, etc., and the temperature of the cleaning solution can be 60°C, 61°C, 62°C, 63°C, 64°C, 65°C, 66°C, 67°C, 68°C, 69°C, 70°C, etc.
[0141] After cleaning, the cleaning machine 1000 uses a disinfection component (not shown in the figure) to blow high-temperature steam onto the items to be cleaned to disinfect them. The disinfection time is between 10 and 20 minutes; for example, the disinfection time can be 10 minutes, 11 minutes, 12 minutes, 13 minutes, 14 minutes, 15 minutes, 16 minutes, 17 minutes, 18 minutes, 19 minutes, 20 minutes, etc.
[0142] After disinfection, the cleaning machine 1000 uses the air supply component 300 to blow high-temperature gas onto the items to be cleaned, drying them by removing moisture from the surface of the items. The drying time is between 10 and 20 minutes, and the temperature of the hot air during drying is between 70°C and 90°C. For example, the drying time can be 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 minutes, and the hot air temperature can be 70°C, 71, 72, 73, 74, 75, 76, 77, 78, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, or 90°C.
[0143] After drying for a certain period of time, the cleaning machine 1000 uses the air supply component 300 to blow cold air to the machine cover 100 to cool the machine cover 100. The cooling time is between 3 minutes and 8 minutes. For example, the cooling time can be 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes, etc. It can be understood that while cooling the machine cover 100, the condensate on the inner surface of the machine cover 100 can also be removed.
[0144] The above are merely specific embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
