Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a washing machine for washing tableware, fruits and vegetables. Background Art

[0002] A dishwasher is a household appliance used for automatic dishwashing, which is very popular among consumers. However, after washing, there is a lot of residual water in the inner tank and on the dishes. This residual water is dried by the residual heat of the inner tank and the dishes. However, due to the large amount of residual water in the inner tank and the rapid cooling of the inner tank, the residual heat of the inner tank is not enough to evaporate the residual water, so there is still a lot of water in the inner tank for a long time after washing the dishes. If the dishwasher door is closed for a long time, the odor in the dishwasher will be strong and bacteria will easily breed.

[0003] In response to the above problems, the Chinese utility model patent with patent number CN201820319612.0 (publication number CN208958049U) discloses a "drying system for a dishwasher", including an inner tank and a breather, the breather is arranged outside the inner tank, the breather is provided with an exhaust channel, the exhaust channel connects the inside and outside of the inner tank, and also includes a hot air generating device, the hot air generating device is provided with a hot air output end, the hot air output end is connected to the inside of the inner tank, the inner tank is provided with an air duct nut corresponding to the hot air output end, the air duct nut fixes the hot air output end to the inner tank wall, the air duct nut is provided with a hole position, the hole position is connected to the inside of the inner tank and the hot air output end, the hole position includes a central hole and peripheral holes, and the peripheral holes are evenly distributed in a ring shape around the central hole.

[0004] Although the above-mentioned air duct nuts can separate the wind direction, since the wind direction outputs are all located on a single layer, the wind direction is single, resulting in a limited area where the entire hot air can be blown, affecting the drying effect. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a cleaning machine which can separate the wind into multiple layers for blowing, thereby increasing the air supply distance, expanding the air supply area and thus improving the drying effect, in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] A washing machine comprises a box body and a drying component, wherein the side wall of the box body is provided with an air inlet and an air outlet, the drying component is arranged outside the box body and the output end is locked and connected to the air inlet through an air inlet cover, a first opening which passes through in the axial direction is provided in the center of the air inlet cover, a bowl-shaped air guide plate is connected in the first opening, the inner concave surface of the air guide plate faces the washing chamber, and the outer convex surface faces the incoming wind direction, a first air outlet is formed between the outer surface of the air guide plate and the first opening, and a second opening for air to pass through is provided in the center of the air guide plate.

[0008] The utility model provides a bowl-shaped air guide plate in the air inlet cover, with the inner concave surface facing the washing chamber and the outer convex surface facing the incoming wind direction, so that the incoming wind can be divided into at least two layers. The wind in the first layer is blown in radially through the first air outlet on the periphery of the air guide plate, which is beneficial to expanding the blowing range and wind speed of the wind body in this layer. The wind in the second layer is blown in through the second opening, which can cover a large area of ​​the core area of ​​the bowl basket. The utility model divides the wind into multiple layers for blowing, taking into account the air supply range, air supply distance and air blowing volume in the core drying area, which is beneficial to improving the drying effect.

[0009] Preferably, the edge of the air guide plate extends into the washing chamber relative to the edge of the first opening edge, and the arc surface on the back of the air guide plate and the edge of the first opening together enclose the first air outlet, and the air passing area of ​​the first air outlet gradually decreases along the air passing direction. Preferably, along the air passing direction, the first air outlet forms a radial first air guide channel that gradually tilts radially outward from the back of the air guide plate. With the above structure, the air passing area of ​​the first air outlet gradually decreases along the air supply direction, which is conducive to making the air supply speed of the first air outlet higher and the air supply distance longer.

[0010] Preferably, the back of the wind guide plate is provided with a partition rib for separating the wind body, and the partition rib and the wind guide plate together enclose a second air outlet corresponding to the center of the wind guide plate and a third air outlet located outside the second air outlet, and the second air outlet and the third air outlet together constitute the second opening. With the above structure, the air duct inside the first air outlet is divided again, which is conducive to expanding the air supply area and improving the air supply effect.

[0011] Preferably, at least part of the partition ribs are arranged obliquely so that the third air outlet forms a second air guide channel that spreads radially outward relative to the second air outlet. This structure enables the wind sent into the box by the third air outlet to cover the area between the first air outlet and the second air outlet that may not be covered, thereby increasing the blowing range and eliminating the drying dead corner.

[0012] Preferably, the partition ribs enclose a hexagonal structure, the outer tip of the hexagonal structure is connected to the inner wall of the first opening, the central part of the hexagonal structure forms a hexagonal second air outlet, and each corner of the hexagonal structure constrains the third air outlet. The above structure is conducive to expanding the drying range.

[0013] Preferably, the downstream parts of the partition ribs corresponding to the corners of the hexagonal structure and adjacent to the hexagonal structure are radially inclined outward to form an air guiding slope, which is used to form a diffusion structure of the second air guiding channel. This structure can not only directional guide the wind passing through the third air outlet, but also reduce the air passing area of ​​the third air outlet, thereby increasing the wind speed and the air supply distance.

[0014] Preferably, the second air outlet forms a third air guide channel that allows air to blow vertically into the washing chamber. This structure allows the second air outlet to blow directly at the core area of ​​the bowl basket, thereby improving the drying effect.

[0015] Preferably, along the wind direction, the first air outlet forms a first air guide channel that gradually inclines radially outward from the back of the air guide plate, and the radial inclination of the first air guide channel is greater than the radial diffusion inclination of the second air guide channel. This structure can guide the wind direction of the first air outlet and the third air outlet in layers, expanding the blowing range and drying effect.

[0016] Compared with the prior art, the advantages of the utility model are: the utility model is provided with a bowl-shaped air guide plate in the air inlet cover, and the inner concave surface is facing the washing chamber, and the outer convex surface is facing the incoming wind direction, so that the incoming wind can be divided into at least two layers. The wind in the first layer is blown in radially through the first air outlet on the periphery of the air guide plate, which is beneficial to expanding the blowing range and wind speed of the wind body in this layer. The wind in the second layer is blown in through the second opening, which can cover a large area of ​​the core area of ​​the bowl basket. The utility model divides the wind into multiple layers for blowing, taking into account the air supply range, air supply distance and air blowing volume in the core drying area, which is beneficial to improving the drying effect.

[0023] The edge of the air guide plate 3 extends into the washing chamber relative to the edge of the first opening 211, and the arc surface on the back of the air guide plate 3 and the edge of the first opening 21 together enclose the first air outlet 211, and the air passing area of ​​the first air outlet 211 gradually decreases along the air passing direction. Along the air passing direction, the first air outlet 211 forms a radial first air guide channel that gradually tilts outward along the radial direction from the back of the air guide plate 3. With the above structure, the air passing area of ​​the first air outlet 211 gradually decreases along the air supply direction, which is conducive to making the air supply speed of the first air outlet 211 higher and the air supply distance longer.

[0024] The back of the air guide plate 3 is provided with a partition rib 4 for partitioning the air body, and the partition rib 4 and the air guide plate 3 together enclose a second air outlet 311 corresponding to the center of the air guide plate 3 and a third air outlet 312 located outside the second air outlet 311, and the second air outlet 311 and the third air outlet 312 together constitute a second opening 31. With the above structure, the air duct inside the first air outlet 211 is divided again, which is conducive to expanding the air supply area and improving the air supply effect.

[0025] At least part of the partition ribs 4 are arranged tilted so that the third air outlet 312 forms a second air guide channel that spreads radially outward relative to the second air outlet 311. This structure enables the wind sent into the box body 1 by the third air outlet 312 to cover the area between the first air outlet 211 and the second air outlet 311 that may not be covered, thereby increasing the blowing range and eliminating the drying dead corner.

[0026] The partition ribs 4 of this embodiment enclose a hexagonal structure, the outer tip of the hexagonal structure is connected to the inner wall of the first opening 21, the central part of the hexagonal structure forms a hexagonal second air outlet 311, and each corner of the hexagonal structure constrains the third air outlet 312.

This structure can not only directional guide the wind passing through the third air outlet 312, but also reduce the air passing area of ​​the third air outlet 312, thereby increasing the wind speed and the air supply distance.

[0028] The second air outlet 311 forms a third air guide channel that allows air to be blown vertically into the washing chamber. This structure allows the second air outlet 311 to blow directly at the core area of ​​the bowl basket, thereby improving the drying effect.

[0029] In the wind direction, the first air outlet 211 forms a first air guide channel that gradually inclines radially outward from the back of the air guide plate 3, and the radial inclination of the first air guide channel is greater than the radial diffusion inclination of the second air guide channel. This structure can guide the wind direction of the first air outlet 211 and the third air outlet 312 in layers, thereby expanding the blowing range and drying effect.

The wind in the first layer is blown in radially through the first air outlet 211 on the periphery of the air guide plate 3, which is beneficial to expanding the blowing range and wind speed of the wind body in this layer. The wind in the second layer is blown in radially through the third air outlet 312 at a smaller inclination than the first air outlet 211. The wind in the third layer is blown vertically into the box body 1 through the second air outlet 311, taking into account the air supply range, air supply distance and air blowing volume in the core drying area, which is beneficial to improving the drying effect.
