Description

Technical Field

[0001] This utility model belongs to the field of cleaning machine technology, and in particular relates to an exhaust and water-blocking structure for a small cleaning machine. Background Technology

[0002] With the rapid development of the dishwashing machine industry, dishwashing machines are becoming increasingly popular in homes. Because different families have different sizes and shapes of tableware, dishwashing machines of various capacities and sizes are available on the market. Smaller dishwashing machines are available for smaller apartments, suitable for use in limited living spaces. Most existing exhaust and water-blocking structures use multi-layered, staggered baffles to create airflow and water separation channels. These structures require a certain vertical installation height, resulting in a corresponding increase in the overall height and size of the machine. Utility Model Content

[0003] The purpose of this utility model is to provide an exhaust and water-blocking structure for a small cleaning machine, which solves the problem that the exhaust and water-blocking mechanism of existing small cleaning machines requires a lot of internal installation space, resulting in a large overall size.

[0004] To achieve the above objectives, this utility model provides an exhaust and water-blocking structure for a small cleaning machine, including a top cover, a cover plate, and a baffle. The top of the top cover is recessed downward to form a groove, and the bottom of the groove extends upward to form an annular enclosure wall. The bottom area of ​​the annular enclosure wall is provided with a first air outlet penetrating the top cover. The side wall of the annular enclosure wall is provided with a through opening. On both sides of the opening, guide plates extend from the annular enclosure wall toward the inner side wall of the groove. The cover plate covers the top of the annular enclosure wall and, together with the guide plates and the groove, defines a second air outlet communicating with the external environment. The opening connects the first air outlet and the second air outlet. The baffle is located below the groove and forms an air passage gap with the bottom surface of the groove.

[0005] Furthermore, the top surface of the baffle has an upwardly arched arc structure.

[0006] Furthermore, the bottom surface of the groove is provided with a downwardly extending slot, and the top surface of the baffle is provided with an upwardly extending post, which is inserted into the slot.

[0007] Furthermore, the groove is provided with a mounting hole that extends through the slot, and the top of the insert post is provided with a connecting hole, which is connected by a locking member passing through the mounting hole and the connecting hole.

[0008] Furthermore, the bottom of the groove is provided with a through slot, and the bottom surface of the cover plate is provided with a downwardly extending buckle. The buckle engages with the slot, so that the cover plate is tightly attached to the top of the annular enclosure wall.

[0009] Furthermore, the side of the groove between the two guide plates that is close to the second air outlet is an inclined surface.

[0010] Furthermore, the distance between the two guide vanes gradually increases from the opening along the air outlet direction.

[0011] The exhaust and water-blocking structure of the small cleaning machine provided in this embodiment of the present invention has at least the following technical effects:

[0012] The small washer has a washing chamber inside, where water flows to rinse items. A groove is formed in the top cover of the small washer, with a baffle below the groove and a ventilation gap between the bottom of the groove and the baffle. The groove extends upward to form an annular enclosure wall. The bottom of the annular enclosure wall has a through-hole first vent, and the side wall of the annular enclosure wall has through-openings. Guide plates are located on both sides of the openings facing the inner side wall of the groove. A cover plate covers the top of the annular enclosure wall and defines a second vent. The opening connects the first and second vents, allowing steam inside the washer to pass through the ventilation gap, the first vent, the opening, and the second vent, ultimately being discharged into the external environment. The baffle prevents water from splashing out of the top cover, but does not prevent steam from entering the ventilation gap. The overall structure of the exhaust and water-blocking system is relatively simple. The air outlet is located at the top of the cover, and the cover plate covers the air outlet without taking up too much vertical installation space of the cleaning machine, which makes it easier to further reduce the size of the machine and make it suitable for more small-sized families.

[0028] In one embodiment of the exhaust and water-blocking structure of the small cleaning machine of this utility model, please refer to... Figures 1 to 7 The exhaust and water-blocking structure of the small cleaning machine includes a top cover 100, a cover plate 200, and a baffle 300. The top of the top cover 100 is recessed downward to form a groove 110. The bottom of the groove 110 extends upward to form an annular enclosure wall 120. The bottom area of ​​the annular enclosure wall 120 is provided with a first air outlet 121 that penetrates the top cover 100. The side wall of the annular enclosure wall 120 is provided with a through opening 122. On both sides of the opening 122, guide plates 123 extend from the annular enclosure wall 120 toward the inner side wall of the groove 110. The cover plate 200 covers the top of the annular enclosure wall 120 and, together with the guide plate 123 and the groove 110, defines a second air outlet 130 that communicates with the external environment. The opening 122 connects the first air outlet 121 and the second air outlet 130. The baffle 300 is located below the groove 110 and forms an air passage gap 310 between it and the bottom surface of the groove 110.

[0029] Specifically, the small washing machine has a washing chamber inside, where water flows to rinse items. A groove 110 is provided on the top cover 100 of the small washing machine, and a baffle 300 is provided below the groove 110. A ventilation gap 310 exists between the bottom surface of the groove 110 and the baffle 300. The groove 110 extends upward to form an annular enclosure wall 120. A first through-hole vent 121 is provided at the bottom of the annular enclosure wall 120, and an through-hole vent 122 is provided on the side wall of the annular enclosure wall 120. Guide plates 123 are located on both sides of the vent 122 facing the inner side wall of the groove 110. A cover plate 200 covers the top of the annular enclosure wall 120 and defines a second vent 130. The vent 122 connects the first vent 121 and the second vent 130, allowing steam inside the washing machine to pass through the ventilation gap 310, the first vent 121, the vent 122, and the second vent 130, ultimately being discharged into the external environment. The baffle 300 serves to prevent water from the inside of the washer from flowing out of the top cover 100, thus preventing water from splashing out of the washer from the inside, but it does not affect the entry of steam into the ventilation gap 310. The overall structure of the exhaust and water-blocking system is relatively simple. The air outlet is located at the top of the top cover 100, and the cover plate 200 covers the air outlet, which does not take up too much vertical installation space of the washer, making it easier to further reduce the size of the machine and making it suitable for more small-apartment families.

[0030] For further details, please refer to... Figure 3 The top surface of the baffle 300 has an upward-arched arc structure. Specifically, the arc-shaped baffle acts as a guide. When a small amount of water splashes into the ventilation gap, the baffle 300 causes the water to flow back into the interior of the cleaning machine, preventing water from accumulating on the top surface of the baffle 300.

[0031] Preferably, the outer diameter of the baffle 300 is larger than the inner diameter of the first air outlet 121. Specifically, this ensures that the baffle 300 prevents water from the inside of the cleaning machine from directly entering the first air outlet 121.

[0032] For further details, please refer to... Figure 6 and Figure 7 The bottom surface of the groove 110 is provided with a downwardly extending slot 140, and the top surface of the baffle 300 is provided with an upwardly extending post 320, which is inserted into the slot 140. Specifically, the insertion of the post 320 into the slot 140 fixes the baffle 300 below the groove 110, and the downwardly extending slot 140 and the upwardly extending post 320 form an air gap 310 between the bottom surface of the groove 110 and the top surface of the baffle 300.

[0033] For further details, please refer to... Figure 5 and Figure 7The groove 110 has a mounting hole 150 extending through to the slot 140, and the top of the insert 320 has a connecting hole 321. A locking member is inserted through the mounting hole 150 and the connecting hole 321 for connection. Specifically, the locking member connects the mounting hole 150 and the connecting hole 321 to further stabilize the baffle 300, making it less likely to be knocked off the groove 110 of the top cover by water flow.

[0034] For further details, please refer to... Figures 3 to 5 The bottom of the groove 110 has a through slot 160, and the bottom surface of the cover plate 200 has a downwardly extending buckle 210. The buckle 210 engages with the slot 160, so that the cover plate 200 is tightly attached to the top of the annular enclosure wall 120. Specifically, the cover plate 200 is fixed to the groove 110 by the buckle 210 engaging with the slot 160, making assembly convenient. The cover plate 200 is tightly attached to the top of the annular enclosure wall 120, so that steam, after passing through the first outlet 121, can only be discharged to the external environment along the path of the opening 122 and the second outlet 130.

[0035] Preferably, the top ends of the two guide plates 123 are coplanar with the top end of the annular enclosure wall 120. Specifically, the coplanar arrangement ensures that the portion of the cover plate 200 located on the outer side of the annular enclosure wall 120 is also in close contact with the top surface of the guide plates 123, ensuring that steam is discharged from the second outlet 130.

[0036] For further details, please refer to... Figure 3 The groove 110 between the two guide plates 123 has an inclined surface 170 on the side near the second air outlet 130. Specifically, when a large amount of steam is discharged to the outside through the second air outlet 130 from the opening 122, some of the steam will condense into water and accumulate in the space enclosed by the two guide plates 123 and the groove 110. The inclined surface 170 allows this part of the condensate to flow back into the interior of the cleaning machine.

[0037] For further details, please refer to... Figure 5 The distance between the two guide vanes 123 gradually widens from the opening 122 along the exhaust direction. Specifically, steam enters the gradually widening second exhaust port 130 from the narrow opening 122, guiding the steam outward and improving exhaust efficiency.

[0038] Preferably, a support column 124 is also provided at the opening 122, with the bottom end of the support column 124 connected to the groove 110, and the top end of the support column 124 being coplanar with the top end of the annular enclosure wall 120. Specifically, the support column 124 supports part of the cover plate 200 above the opening 122, enhancing stability.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
