Description

Technical Field

[0001] This utility model relates to the technical field of cleaning machines, and in particular to a top cover assembly for a cleaning machine and the cleaning machine itself. Background Technology

[0002] Dishwashers, bottle washer machines, fruit and vegetable washers, and other cleaning equipment have become key home appliances for improving quality of life and cleaning efficiency. The core working principle of these devices typically involves the synergistic effect of high-temperature, high-pressure water jets and cleaning agents to remove stains. After washing, tableware, bottles, and other cleaned items are dried using methods such as hot air drying or natural air drying to prevent residual moisture from breeding bacteria. The exhaust system, as a core component of the cleaning equipment, primarily functions to promptly expel high-temperature water vapor, cleaning agent evaporation gases, and air generated within the equipment's cavity during the washing and drying process. This ensures pressure balance within the cavity and simultaneously introduces fresh air into the drying system, guaranteeing both drying effectiveness and operational safety.

[0003] Existing cleaning machines often use a combination of independent exhaust channels and external fans for their exhaust mechanisms. The exhaust channels are usually integrated into the housing on the side wall, back, or bottom of the equipment. This requires a separate design of complex air duct cavities and sealing structures, which not only occupies valuable installation space inside the equipment and reduces the volume of the cleaning chamber, especially in small tabletop cleaning machines and mini baby bottle cleaning machines, but also increases the assembly process and production cost of the entire machine.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] This utility model addresses the problem mentioned above where the exhaust channel in existing cleaning machines is usually integrated inside the shell on the side wall, back, or bottom of the equipment. This requires a separate design of a complex air duct cavity and sealing structure, which not only occupies valuable installation space inside the equipment and reduces the volume of the cleaning chamber, but also increases the assembly process and production cost of the entire machine. This utility model proposes a top cover assembly for a cleaning machine and a cleaning machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A top cover assembly for a cleaning machine includes a top cover body and an end cover disposed on the upper part of the top cover body. The top cover body has an exhaust channel communicating with a cleaning chamber inside the cleaning machine. An exhaust gap is provided between the end cover and the top cover body to allow the exhaust channel to communicate with the outside. The end cover has a first water-blocking wall extending toward the bottom wall of the exhaust channel. The first water-blocking wall has a first communication port communicating with the exhaust channel.

[0007] As described above, the top cover assembly of a cleaning machine has a first extension extending downward, and a plurality of vent holes are provided at the bottom of the first extension. Each vent hole is connected to the vent channel. The inner side of the first extension has an inner cavity that is connected to the vent holes and the vent channel. The side wall of the first extension located below the vent channel forms a second water-blocking wall, and the first water-blocking wall is located on one side of the second water-blocking wall.

[0008] As described above, the top cover assembly of a cleaning machine has a first mounting portion located on one side of the first extension and connected to the end cover. The end cover has a second mounting portion corresponding to the first mounting portion.

[0009] As described above, the top cover assembly of a cleaning machine further includes a stepped portion located above the first extension portion, a first positioning portion located on one side of the first mounting portion, and a second positioning portion corresponding to the first positioning portion on the end cover.

[0010] In the top cover assembly of a cleaning machine as described above, the first mounting portion, the first positioning portion, and the exhaust channel are arranged circumferentially spaced along the first extension portion, and the first mounting portion and the first positioning portion are higher than the exhaust channel.

[0011] As described above, in the top cover assembly of a cleaning machine, the exhaust channel extends circumferentially within the top cover body, and the width of the exhaust channel gradually increases radially outward.

[0012] As described above, the top cover assembly of a cleaning machine has a second extension extending toward the bottom wall of the exhaust channel on the side wall of the end cover. There are several second extensions, and each second extension has a second communication port on both sides that connects the exhaust channel to the outside.

[0013] As described above, the top cover assembly of a cleaning machine has a plurality of first water-blocking walls, and each of the first water-blocking walls has a first connecting port on both sides.

[0014] In the top cover assembly of a cleaning machine as described above, a reinforcing part connected to the end cover is provided on one side of any of the first water-retaining walls.

[0015] This utility model also provides a cleaning machine, including a cleaning machine body and an upper cover assembly as described above. The upper cover body is disposed on the cleaning machine body, and the upper cover body and the cleaning machine body enclose a cleaning chamber. The exhaust channel is connected to the cleaning chamber.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention improves the upper cover assembly of the cleaning machine by integrating the exhaust channel into the upper cover body.

[0022] Example 1: like Figures 1 to 7 As shown, this utility model provides a top cover assembly 100 for a cleaning machine. The top cover assembly 100 can be installed in cleaning equipment such as dishwashers and bottle cleaners. The top cover assembly 100 includes a top cover body 110 and an end cap 120. The end cap 120 is disposed on the upper part of the top cover body 110. The top cover body 110 is provided with an exhaust channel 111 that communicates with the cleaning chamber inside the cleaning machine. An exhaust gap 130 is provided between the end cap 120 and the top cover body 110 to allow the exhaust channel 111 to communicate with the outside. The exhaust channel 111 and the exhaust gap 130 communicate with the cleaning machine in sequence. The cavity is connected, allowing the steam in the cleaning cavity to be discharged to the outside of the cleaning machine sequentially through the exhaust channel 111 and the exhaust gap 130. The end cover 120 is provided with a first water-blocking wall 121 extending toward the bottom wall of the exhaust channel 111. The first water-blocking wall 121 is provided with a first connecting port 1211 communicating with the exhaust channel 111. The first water-blocking wall 121 is vertically arranged in the exhaust channel 111. By providing the first connecting port 1211 in the first water-blocking wall 121, the first water-blocking wall 121 is prevented from blocking the exhaust channel 111, ensuring normal exhaust of the exhaust channel 111.

[0023] This invention improves the upper cover assembly 100 of the cleaning machine by integrating the exhaust channel 111 into the upper cover body 110. Steam in the cleaning chamber can rise directly and be discharged to the outside through the exhaust channel 111, shortening the exhaust path of the cleaning machine and improving drying efficiency. Secondly, compared to the traditional method of setting the exhaust mechanism inside the cleaning chamber, the exhaust channel 111 in this invention is set in the upper cover body 110, which increases the capacity of the cleaning chamber, simplifies the exhaust structure of the cleaning machine, reduces assembly steps, thereby improving the production and assembly efficiency of the cleaning machine and reducing production costs. Furthermore, the end cover 120 is provided with a first water-blocking wall 121 extending towards the exhaust channel 111, which prevents high-pressure water from splashing out of the cleaning machine through the exhaust channel 111, ensuring the cleanliness of the outside of the cleaning machine.

[0024] Furthermore, such as Figure 4 and Figure 5 As shown, the upper cover body 110 has a downwardly extending first extension 112. A plurality of vent holes 1121 are provided at the bottom of the first extension 112, and each vent hole 1121 communicates with the vent channel 111. An inner cavity 1122 communicating with the vent holes 1121 and the vent channel 111 is provided inside the first extension 112. A second water-blocking wall 1123 is formed on the side wall of the first extension 112 below the vent channel 111, and the first water-blocking wall 121 is located on one side of the second water-blocking wall 1123. In this embodiment, the first extension 112 is located at the lower part of the center of the upper cover body 110. A plurality of vent holes 1121 are provided longitudinally at the bottom of the first extension 112, through which the cleaning chamber communicates with the vent channel 111. The first extension 112 can be configured as a cylindrical shape. The inner side of the first extension 112 can directly form an inner cavity 1122 that communicates with the exhaust channel 111 and the exhaust hole 1121. The exhaust hole 1121, the inner cavity 1122, the exhaust channel 111, and the exhaust gap 130 are sequentially connected to form an overall air outlet channel in the upper cover assembly 100. A notch is provided on the sidewall of the first extension 112 facing the exhaust channel 111 to allow direct communication between the inner cavity 1122 and the exhaust channel 111, which helps to shorten the exhaust path in the upper cover assembly 100. Furthermore, the end cap 120 is installed on the upper part of the upper cover body 110 and covers the upper part of the exhaust channel 111, preventing dust and other external debris from falling into the cleaning chamber through the exhaust channel 111, keeping the exhaust channel 111 clean, and thus ensuring the cleanliness of the cleaning chamber. It should also be noted that the bottom wall of the first extension 112 can also prevent high-pressure water from splashing out.

[0025] like Figure 4 As shown, the exhaust channel 111 is higher than the exhaust hole 1121, so that the bottom of the first extension 112 and the exhaust channel 111 directly form the second water-blocking wall 1123, and the first water-blocking wall 121 abuts against the bottom wall of the exhaust channel 111 and is close to the second water-blocking wall 1123. In actual application, when the cleaning machine is cleaning, the high-pressure water jet sprayed inside the cleaning machine can splash out through the exhaust hole 1121 to the outside of the upper cover body 110. At this time, the first water-blocking wall 121 and the second water-blocking wall 1123 can block the water from splashing out and guide the water flow into the cleaning chamber to avoid water leakage from the upper cover assembly 100. In addition, the first water-blocking wall 121 abuts against the bottom wall of the exhaust channel 111, which helps to improve the connection stability between the end cover 120 and the upper cover body 110.

[0026] Alternatively, the bottom wall of the exhaust channel 111 may be obliquely downward from the exhaust gap 130 toward the first extension 112, so that the water flow can quickly return to the cleaning chamber.

[0027] In some alternative embodiments, such as Figure 5 As shown, the upper cover body 110 is provided with a first mounting portion 113 located on one side of the first extension portion 112 and connected to the end cover 120. The first mounting portion 113 extends toward the top of the upper cover body 110. The exhaust channel 111 is located on one side of the first mounting portion 113. The end cover 120 is provided with a second mounting portion 122 corresponding to the first mounting portion 113. The first mounting portion 113 is provided with a first mounting hole 1131, and the second mounting portion 122 is provided with a corresponding mounting hole 1131. The second mounting hole 1221; the first mounting hole 1131 and the second mounting hole 1221 are aligned, and the connector passes through the first mounting hole 1131 and the second mounting hole 1221, so that the end cap 120 is detachably installed on the upper part of the upper cover body 110. The installation method of the end cap 120 is simple, and it is convenient for users to disassemble and assemble the end cap 120 and the upper cover body 110, thereby facilitating the cleaning of the upper cover body 110 and the end cap 120; optionally, the connector can be set as a bolt, screw, etc., and this utility model does not make a specific limitation.

[0028] In some alternative embodiments, the first mounting part 113 can be configured as an assembly post, and the second mounting part 122 can be configured as an assembly sleeve adapted to the assembly post. When installing the end cap 120, the end cap 120 can be first snapped onto the assembly post through the assembly sleeve to position the end cap 120. At the same time, the first assembly hole 1131 and the second assembly hole 1221 are aligned to facilitate the installation of the connector, reduce the installation difficulty of the end cap 120, and ensure the rapid assembly of the end cap 120. The inner side of the second assembly hole 1221 is also provided with a limiting boss 1222, and the second assembly hole 1221 passes through the limiting boss 1222. The connector can be assembled to abut against the limiting boss 1222 to further improve the connection stability between the end cap 120 and the upper cover body 110.

[0029] In some alternative embodiments, to further ensure the rapid assembly of the end cap 120, such as... Figure 5 As shown, the upper cover body 110 is further provided with a stepped portion 114 located above the first extension portion 112. The stepped portion 114 extends outward from the periphery of the first extension portion 112. The stepped portion 114 is provided with a first positioning portion 1141 located on one side of the first mounting portion 113. The end cover 120 is further provided with a second positioning portion 123 corresponding to the first positioning portion 1141. The first positioning portion 1141 and the second positioning portion 123 are correspondingly connected. Optionally, the first positioning portion 1141 is configured as a locking block, and the second positioning portion 123 is configured as a locking groove adapted to the locking block. Alternatively, the first positioning portion 1141 is configured as a locking groove, and the second positioning portion 123 is configured as a corresponding locking block. The corresponding connection between the locking block and the locking groove facilitates the positioning of the end cover 120, realizes the rapid assembly of the end cover 120 and the upper cover body 110, and further improves the connection stability of the end cover 120.

[0030] Further optional, such as Figure 5 As shown, the first positioning part 1141 is configured as a locking block, and the second positioning part 123 is configured as a slot adapted to the locking block. The width of the entrance end of the slot is greater than the inner width of the slot. The second positioning part 123 is provided with guide walls 1231 on both sides of the entrance end of the slot. The guide walls 1231 are inclined from top to bottom toward the outside of the slot. By setting the guide walls 1231, it is beneficial to make the slot and the locking block correspondingly engage, so that the end cap 120 can be quickly assembled.

[0031] Optionally, the first mounting portion 113, the first positioning portion 1141, and the exhaust channel 111 are arranged circumferentially spaced along the first extension portion 112, and the first mounting portion 113 and the first positioning portion 1141 are higher than the exhaust channel 111; when the end cap 120 is installed on the upper part of the upper cover body 110, the end cap 120 can be fixed above the exhaust channel 111, which helps to increase the space of the exhaust channel 111 and thus improve the exhaust efficiency.

[0032] In some alternative embodiments, such as Figure 6 As shown, the exhaust channel 111 extends circumferentially in the upper cover body 110, and the width of the exhaust channel 111 gradually increases radially outward, so that the exhaust channel 111 can be set as a fan-shaped annular channel, which is beneficial to increase the space of the exhaust channel 111 and thus improve the exhaust efficiency.

[0033] In some alternative embodiments, such as Figure 4 As shown, the end cap 120 is provided with a second extension 124 extending toward the bottom wall of the exhaust channel 111. There are several second extensions 124. Each second extension 124 has a second connecting port 1241 on both sides to connect the exhaust channel 111 with the outside. The exhaust gap 130 is formed through each second connecting port 1241. In order to further improve the assembly stability of the end cap 120, the second extension 124 extends downward from the end cap 120. During assembly, the second extension 124 will abut against the bottom wall of the exhaust channel 111. At this time, the exhaust channel 111 can be connected to the outside through each second connecting port 1241 to ensure the normal exhaust of the exhaust channel 111.

[0034] Optionally, the top surface of the upper cover body 110 is recessed downwards to form an annular groove 140. When the end cap 120 is installed on the upper part of the upper cover body 110, the peripheral wall of the end cap 120 can extend into the annular groove 140, allowing the peripheral sidewall of the end cap 120 to be hidden within the annular groove 140. This improves the external aesthetics of the upper cover assembly 100 and enhances the connection stability of the end cap 120 to the upper cover body 110. It should be noted that the exhaust gap 130 connects the exhaust channel 111 and the annular groove 140.

[0035] Further optional, such as Figure 6 As shown, the upper cover assembly 100 has an installation area inside the annular groove 140, and the projected area of ​​the exhaust channel 111 can occupy at least 1 / 3 of the installation area, which is beneficial to improving the exhaust efficiency of the exhaust channel 111.

[0036] Alternatively, the outer contour of the end cap 120 can be set to a circle, which helps to improve the aesthetics of the upper cover assembly 100.

[0037] In some alternative embodiments, such as Figure 4 As shown, there are several first water-blocking walls 121, and each first water-blocking wall 121 has a first connecting port 1211 on both sides; each first water-blocking wall 121 is arranged at intervals along the circumference, which can make steam evenly discharged through the exhaust channel 111 and improve exhaust efficiency.

[0038] In some alternative embodiments, to enhance the structural strength of the end cap 120, such as Figure 7 As shown, one side of any of the first water-blocking walls 121 is provided with a reinforcing part 1212 connected to the end cap 120; the reinforcing part 1212 is provided on the side of the first water-blocking wall 121 away from the inner cavity 1122, and the reinforcing part 1212 can be configured as a triangular reinforcing rib, which is beneficial to improve the structural strength of the first water-blocking wall 121, thereby improving the service life of the end cap 120.

[0039] Example 2: Based on the above embodiment one, this embodiment two also provides a cleaning machine, which can be a dishwasher, a baby bottle cleaning machine, etc. The cleaning machine includes a cleaning machine body and an upper cover assembly 100 as described above. The upper cover body 110 covers the cleaning machine body and forms a cleaning chamber by the upper cover body 110 and the cleaning machine body. The exhaust channel 1121 is connected to the cleaning chamber.

[0040] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
