Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of cleaning, and more particularly relates to a drying pipeline and a cleaning machine. BACKGROUND
[0002] The cleaning machine uses washing water to clean the to-be-cleaned articles in the internal cleaning cavity, and the to-be-cleaned articles carry water after being cleaned. In the related art, the cleaning machine can dry the to-be-dried articles by blowing hot air into the cleaning cavity, but the drying efficiency needs to be improved. CONTENT OF THE UTILITY MODEL
[0003] The application aims to provide a drying pipeline and a cleaning machine to improve the drying efficiency.
[0004] To achieve the above-mentioned purpose, the application adopts the technical scheme of:
[0005] In a first aspect, the application provides a drying pipeline, which comprises a first airflow channel. The first airflow channel is provided with an air inlet, and the first airflow channel comprises a main body portion in communication with the air inlet and in the shape of a ring. In this way, hot air can enter the first airflow channel from the air inlet and flow along the main body portion of the first airflow channel, which can increase the flow path of the hot air.
[0006] The drying pipeline provided by the application further comprises a plurality of second airflow channels. The plurality of second airflow channels are connected to the main body portion of the first airflow channel and in communication with the first airflow channel. The second airflow channels and the first airflow channel are both provided with air outlets.
[0007] In this way, hot air can be discharged from the air outlet of the first airflow channel. The hot air can also enter the second airflow channel from the first airflow channel and then be discharged from the air outlet. The second airflow channel can increase the flow path of the hot air, which facilitates the discharge of the hot air from different air outlets, so that the to-be-dried articles can be dried from multiple positions, thereby improving the drying efficiency.
[0008] Therefore, the drying pipeline provided by the application can improve the drying efficiency.
[0009] In some embodiments, the second airflow channels are connected to the outer circumferential side of the main body portion of the first airflow channel.
[0010] In this way, the second airflow channels are located at the outer circumferential side of the main body portion, which can increase the flow range of the hot air and the arrangement range of the air outlets, thereby facilitating the improvement of the drying efficiency.
[0011] In some embodiments, the extension direction of the second airflow channels is tangent to the extension direction of the main body portion.
[0012] This is conducive to the entry of the hot air in the first airflow channel into the second airflow channel.
[0013] In some embodiments, the connection points of the multiple second airflow channels with the main body are equally spaced. In this way, the hot air in the first airflow channel can enter the multiple second airflow channels evenly.
[0014] In some embodiments, the extension direction of the second airflow channel is parallel to or intersects with the plane containing the main body of the first airflow channel.
[0015] The second airflow channel can increase the flow range of hot air in a direction parallel to the plane of the main body of the first airflow channel or in a direction intersecting the plane of the main body of the first airflow channel.
[0016] In this way, the extension direction of the second airflow channel can be specifically set according to product requirements, making it highly adaptable.
[0017] In some embodiments, the first end of the second airflow channel is connected to the main body of the first airflow channel, and the second end of the second airflow channel is closed. In this way, the hot air in the main body of the first airflow channel can enter multiple second airflow channels respectively, preventing the hot air in the first airflow channel from leaking from the second end of the second airflow channel.
[0018] In some embodiments, the first airflow passage further includes an air intake section, which is connected to and communicates with the main body, and the air inlet is located in the air intake section.
[0019] In this way, the air inlet can be connected to the hot air source, and the hot air can enter the main body through the air inlet and the air inlet section facilitates the connection between the drying pipe and the hot air source.
[0020] In some embodiments, the air intake portion is located on the outer periphery of the main body portion, and / or the connection position between the air intake portion and the main body portion is equally spaced from the connection positions between the plurality of second airflow channels and the main body portion.
[0021] In this way, the air intake is located on the outer periphery of the main body, which increases the distance between the main body and the air intake, allowing the main body to be positioned closer to the items to be dried. Furthermore, the connection points between the air intake and the main body are equally spaced, as are the connections between the multiple second airflow channels and the main body, facilitating the even distribution of hot air into the second airflow channels.
[0022] In some implementations, the main body is circular, polygonal, or elliptical.
[0023] In this way, the shape of the main body can be a circular ring, a multi-bordered ring, or an elliptical ring. The shape of the main body can be specifically set according to product requirements, making it highly adaptable.
[0024] Secondly, this application provides a cleaning machine, which includes a cleaning chamber and a drying pipe as described in any of the above embodiments, with the drying pipe located within the cleaning chamber. The cleaning machine provided by this application has the same or similar technical effects as the drying pipe of any of the above embodiments, and will not be elaborated further here.
[0025] In some embodiments, the cleaning machine provided in this application further includes a first shelf and a second shelf, the second shelf being higher than the first shelf, the drying pipe being located close to the first shelf, and the air outlet being located towards the second shelf.
[0026] In this way, the cleaning machine provided in this application can use the drying pipe to blow hot air to dry the items to be dried on the first shelf and the second shelf.
[0027] In some embodiments, the cleaning machine provided in this application further includes a spraying device, which includes a first spraying assembly disposed along the first shelf and a second spraying assembly disposed along the second shelf.
[0028] In this way, the cleaning machine provided in this application can use the first spray assembly to spray and clean the items to be cleaned on the first shelf, and can also use the second spray assembly to spray and clean the items to be cleaned on the second shelf.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0042] Please refer to the following: Figure 1 , Figure 2 and Figure 3This application provides a cleaning machine 100, which includes a body 20 on which components such as a washing pump and a sewage pump (not shown in the figure) can be installed.
[0043] The cleaning machine 100 provided in this application embodiment also includes a machine cover 10, which is connected to the machine body 20 and can be enclosed to form a cleaning chamber 101.
[0044] The cleaning machine 100 provided in this application embodiment also includes a spray device 30, which can be disposed in the cleaning chamber 101 and can clean the items to be cleaned in the cleaning chamber 101.
[0045] The inventors discovered that the washing machine 100 uses washing water to clean the items to be cleaned in the internal washing chamber 101. After being cleaned, the items still contain moisture, and the cleaned items need to be dried. In related technologies, the washing machine 100 can dry the items to be dried by blowing hot air into the washing chamber 101, but the drying efficiency needs to be improved.
[0046] To address the aforementioned technical problems, this application provides a drying pipe 35 for drying items washed within the cleaning chamber 101. The drying pipe 35 can be disposed inside the cleaning chamber 101.
[0047] Optionally, the cleaning machine 100 may be equipped with a hot air source installed on the machine body 20, which can supply hot air to the drying duct 35. The hot air source may include a fan and a heating element, which heats the air blown out by the fan. It should be noted that "air" can refer to flowing air, hot air refers to hot air, and cold air refers to cold air.
[0048] Optionally, the drying pipe 35 can be installed on the spray device 30. For example, the drying pipe 35 is fixed to the bottom of the spray device 30 and can dry the items to be dried carried on the spray device 30.
[0049] Optionally, please refer to Figure 3 and Figure 4 The drying pipe 35 may include a connecting frame 3, and the drying pipe 35 can be installed on the spray device 30 through the connecting frame 3.
[0050] Please see Figure 4 and Figure 5 The drying duct 35 provided in this embodiment includes a first airflow channel 1, which has an air inlet 01 and a main body portion 11 that is connected to the air inlet 01 and is annular. In this way, hot air can enter the first airflow channel 1 from the air inlet 01 and can flow along the main body portion 11 of the first airflow channel 1, thereby increasing the flow path of the hot air.
[0051] Optionally, the main body 11 of the first airflow channel 1 can be circular, polygonal, or elliptical.
[0052] For example, when the main body portion 11 of the first airflow channel 1 is annular, the main body portion 11 extends around the circular closed line.
[0053] For example, when the main body portion 11 of the first airflow channel 1 is a polygon, the main body portion 11 extends around the polygonal closing line, which can be a multi-line segment connected end to end.
[0054] For example, when the main body portion 11 of the first airflow channel 1 is elliptical, the first airflow channel 1 extends around the elliptical closed line.
[0055] In this way, the shape of the main body 11 of the first airflow channel 1 can be specifically set according to product requirements, which has good applicability.
[0056] Please continue reading. Figure 4 and Figure 5 The drying pipe 35 provided in this embodiment further includes a plurality of second airflow channels 2, which are connected to the main body portion 11 of the first airflow channel 1 and are in communication with the first airflow channel 1. Specifically, the second airflow channels 2 are directly connected to the main body portion 11.
[0057] Optionally, both the first airflow channel 1 and the second airflow channel 2 are provided with an air outlet 02.
[0058] In this way, hot air can be discharged from the air outlet 02 of the first airflow channel 1 or from the air outlet 02 of the second airflow channel 2. That is, hot air is discharged from different air outlets 02, so that the items to be dried can be dried from multiple locations.
[0059] In addition, hot air can enter the second airflow channel 2 from the first airflow channel 1 and then be discharged from the air outlet 02 of the second airflow channel 2. The second airflow channel 2 can increase the flow path of hot air, which is conducive to the hot air being discharged from different air outlets 02 of the second airflow channel 2. Thus, the items to be dried can be dried from multiple positions, thereby improving the drying efficiency.
[0060] Therefore, the drying pipe 35 provided in this embodiment can improve drying efficiency.
[0061] Please continue reading. Figure 4 and Figure 5In some embodiments, the second airflow channel 2 is connected to the outer periphery of the first airflow channel 1. It is understood that when the second airflow channel 2 is connected to the outer periphery of the first airflow channel 1, the hot air in the first airflow channel 1 needs to flow outwards, thus exceeding the range defined by the first airflow channel 1. Therefore, the drying pipe 35 provided in this application embodiment, by placing the second airflow channel 2 on the outer periphery of the first airflow channel 1, can increase the flow range of the hot air.
[0062] Furthermore, the air outlet 02 can be located not only on the first airflow channel 1, but also on the second airflow channel 2, thus the air outlet 02 can extend beyond the range defined by the first airflow channel 1. Therefore, the second airflow channel 2 can increase the arrangement range of the air outlet 02, which is beneficial to improving drying efficiency.
[0063] Please continue reading. Figure 4 and Figure 5 In some embodiments, the extension direction of the second airflow channel 2 is tangent to the extension direction of the first airflow channel 1. It is understood that when the extension direction of the first airflow channel 1 is tangent to the extension direction of the second airflow channel 2, at the connection point between the first airflow channel 1 and the second airflow channel 2, the flow direction of the hot air in the first airflow channel 1 can be the same as the flow direction of the hot air in the second airflow channel 2. This reduces the resistance encountered by the hot air in the first airflow channel 1 as it enters the second airflow channel 2, facilitating its entry.
[0064] Please continue reading. Figure 4 and Figure 5 In some examples, the extension direction of the second airflow duct 2 can be parallel to the plane where the main body 11 of the first airflow duct 1 is located. In this way, the second airflow duct 2 can increase the flow range of hot air in a direction parallel to the plane where the main body 11 of the first airflow duct 1 is located.
[0065] In some embodiments, the connection points of the plurality of second airflow channels 2 with the main body portion 11 are equally spaced. This allows hot air from the first airflow channel 1 to enter the plurality of second airflow channels evenly. Furthermore, the plurality of second airflow channels 2 can evenly discharge hot air to the outside through their own air outlets 02.
[0066] In other examples, the extension direction of the second airflow duct 2 may also intersect with the plane containing the main body 11 of the first airflow duct 1. In this way, the second airflow duct 2 can increase the flow range of hot air in the direction intersecting with the plane containing the main body 11 of the first airflow duct 1.
[0067] Understandably, the extension direction of the second airflow channel 2 can be specifically set according to product requirements, making it highly adaptable.
[0068] Please continue reading. Figure 4 andFigure 5 In some embodiments, the first end 21 of the second airflow channel 2 is connected to the main body portion 11 of the first airflow channel 1, and the second end 22 of the second airflow channel 2 is closed.
[0069] It is understandable that when the second end 22 of the second airflow channel 2 is open, the hot air in the second airflow channel 2 can flow out from the second end 22 of the second airflow channel 2 without changing its flow direction. This will cause the hot air in the first airflow channel 1 to preferentially enter the second airflow channel 2 which is closer to the air inlet 01, affecting the usage effect of other second airflow channels 2, and thus affecting the drying effect of the drying positions corresponding to other second airflow channels 2.
[0070] Therefore, the drying pipe 35 provided in this embodiment of the application seals the second end 22 of the second airflow channel 2, preventing hot air in the first airflow channel 1 from leaking from the second end 22 of the second airflow channel 2. The hot air in the first airflow channel 1 can enter the multiple second airflow channels 2 as evenly as possible, which is beneficial to improving the drying effect.
[0071] Please continue reading. Figure 4 and Figure 5 In some embodiments, the first airflow channel 1 provided in this application embodiment further includes an air intake portion 12, which is connected to and communicates with the main body portion 11, and the air inlet 01 is located at the third end of the air intake portion 12.
[0072] Optionally, the third end 121 of the air intake section 12 is connected to the main body 11 of the first airflow channel 1, and the fourth end 122 of the air intake section 12 is connected to the air intake port 01.
[0073] In this way, the air inlet 01 can be connected to the hot air source, and the hot air can enter the main body 11 of the first airflow channel 1 through the air inlet 01 and the air intake part 12 of the first airflow channel 1. The air intake part 12 facilitates the connection between the drying pipe 35 and the hot air source.
[0074] In some embodiments, the second end 22 of the second airflow channel 2 is located on one side of the first end 21 of the second airflow channel 2 along the counterclockwise and clockwise directions of the first airflow channel 1, and the fourth end 122 of the air intake portion 12 is located on the other side of the third end 121 of the air intake portion 12 along the counterclockwise and clockwise directions of the first airflow channel 1.
[0075] In this way, the air inlet section 12, the main body section 11 of the first airflow channel 1, and the hot air in the second airflow channel 2 can all flow in either a clockwise or counterclockwise direction, which facilitates the flow of hot air.
[0076] For example, the second end 22 of the second airflow channel 2 is located at the first end 21 of the second airflow channel 2 in a counterclockwise direction along the first airflow channel 1 (e.g., Figure 4On one side of the D direction in the middle, the fourth end 122 of the intake section 12 is located in the clockwise direction of the third end 121 of the intake section 12 along the first airflow channel 1 (e.g., in the direction of D). Figure 4 The side opposite to the direction of D. Among them, the air inlet section 12, the main body section 11 of the first airflow channel 1 and the flow direction of hot air in the second airflow channel 2 can all be counterclockwise.
[0077] Please continue reading. Figure 4 and Figure 5 In some embodiments, the air intake portion 12 is located on the outer periphery of the first airflow channel 1. In this way, the air intake portion 12 can increase the distance between the first airflow channel 1 and the air inlet 01, which is beneficial for the first airflow channel 1 to be arranged closer to the item to be dried.
[0078] In some embodiments, the connection position between the air intake portion 12 and the main body portion 11 is equally spaced from the connection positions between the plurality of second airflow channels 2 and the main body portion 11. It can be understood that the connection position between the air intake portion 12 and the main body portion 11 is a first connection position, and the connection positions between the second airflow channels 2 and the main body portion 11 are second connection positions, with the first connection position and the plurality of second connection positions equally spaced. That is, the main body portion 11 includes a plurality of equally spaced connection positions, one of which is the first connection position, and the remaining connection positions are the second connection positions.
[0079] In this way, the hot air from the intake section 12 can enter the second airflow channel 2 evenly.
[0080] In some embodiments, the air intake portion 12 of the first airflow channel 1 is tangent to the main body portion 11, facilitating the entry of hot air from the air intake portion 12 into the main body portion 11. It is understood that when the main body portion 11 of the first airflow channel 1 is tangent to the air intake portion 12, the flow direction of the hot air in the air intake portion 12 at the connection point between the main body portion 11 and the air intake portion 12 can be the same as the flow direction of the hot air in the main body portion 11 of the first airflow channel 1. This results in less resistance to the hot air in the air intake portion 12 entering the main body portion 11, facilitating the entry of the hot air in the air intake portion 12 into the main body portion 111.
[0081] In some embodiments, the air outlet 02 includes a first air outlet 021 and a second air outlet 022, wherein the first air outlet 021 is located along a first airflow channel 1 and a second airflow channel 2 in a first direction (e.g., Figure 4 On one side of the Z direction, the second air outlet 022 is located on the other side of the first airflow channel 1 and the second airflow channel 2 along the first direction, which is perpendicular to the plane where the main body part 11 is located.
[0082] For example, please see Figure 4The first air outlet 021 is located on side B of the first airflow channel 1 and the second airflow channel 2. Please refer to [link / reference]. Figure 5 The second air outlet 022 is located on the C side of the first airflow channel 1 and the second airflow channel 2.
[0083] It is understandable that the air outlet 02 is located on both sides of the first airflow channel 1 and the second airflow channel 2 along the first direction, which can blow hot air in different directions, thus improving drying efficiency.
[0084] In addition, when the first direction is vertical, the opening direction of the first air outlet 021 or the second air outlet 022 can be downward, so that the water in the drying pipe 35 can flow out.
[0085] For example, the opening direction of the second air outlet 022 is downward.
[0086] Please continue reading. Figure 4 and Figure 5 In some embodiments, the drying pipe 35 has a tubular structure and a pipe wall that extends in the same direction as the first airflow channel 1 and the second airflow channel 2. This makes the drying pipe 35 easier to manufacture.
[0087] Please see Figure 6 In other embodiments, the drying pipe 35 can be a plate-like structure formed by injection molding or casting. The portion of the drying pipe 35 other than the first airflow channel 1 and the second airflow channel 2 can be a solid structure. That is, the first airflow channel 1 and the second airflow channel 2 are cavities disposed inside the drying pipe 35.
[0088] It is understandable that the drying pipe can be part of the wall panel surrounding the cleaning chamber 101 of the cleaning machine 100. In this way, the first airflow channel 1 and the second airflow channel 2 can be integrated into the wall of the machine body 20 or the machine cover 10 surrounding the cleaning chamber 101.
[0089] Optionally, the cleaning machine 100 provided in this application embodiment has the same or similar technical effects as the drying pipe 35 in any of the above embodiments, which will not be described again here.
[0090] Optionally, the spray device 30 includes a first shelf 31 and a second shelf 32, the second shelf 32 being higher than the first shelf 31, the drying pipe being located close to the first shelf 31, and the air outlet being located towards the second shelf 32.
[0091] Optionally, the drying duct is located at the bottom of the first shelf 31.
[0092] Optionally, the drying duct can be installed on the first shelf 31.
[0093] In this way, the cleaning machine provided in this application can use the drying pipe to blow hot air to dry the items to be dried on the first shelf 31 and the second shelf 32.
[0094] Optionally, the spray device includes a first spray assembly 33 disposed along the first shelf 31 and a second spray assembly 34 disposed along the second shelf 32.
[0095] In this way, the cleaning machine provided in this application can use the first spray assembly 33 to spray and clean the items to be cleaned on the first shelf 31, and can also use the second spray assembly 34 to spray and clean the items to be cleaned on the second shelf 32.
[0096] 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.
