Description

Technical Field

[0001] The present invention relates to the technical field of dishwashers, and in particular to a dishwasher inner tank structure and a dishwasher. Background Art

[0002] The most common dishwashers in general households are desktop dishwashers or cabinet dishwashers. Household dishwashers are small in size, take up little space, have small capacity, are flexible to place, have good decontamination effects, and have disinfection and drying functions. Today's desktop dishwashers are highly automated and do not require human supervision. They can automatically complete the washing, rinsing, drying, and disinfection functions.

[0003] In the prior art, the inner tank of a dishwasher is a horizontal structure. During the washing and drying process, a large number of splashing water droplets or water droplets condensed from evaporation of water vapor gather on the top cover of the inner tank. The water droplets are affected by gravity and are likely to drip and wet the dishes after drying, affecting the cleanliness of washing and the effect of drying.

[0004] Patent No. CN203828882U discloses a dishwasher inner tank and a dishwasher, wherein the inner top wall is arranged in an inclined or curved shape, and the internal tension of some water droplets may overcome gravity and flow along the inner top to the side wall, but no drainage structure is arranged on the inner top wall, and only a channel for the flow of water droplets is formed according to the shape of the inner top wall, and the drainage effect is not good.

[0005] It can be seen from this that it is necessary to invent an inner pot structure that can prevent water droplets from dripping from the front side of the inner pot top cover onto the dishes. Summary of the invention

[0006] The problem solved by the invention is that water drops on the top cover of the inner tank of the dishwasher drip onto the dishes, thus affecting the washing and drying effects.

[0007] In order to solve the above problems, the present invention provides an inner tank structure of a dishwasher.

[0008] A dishwasher inner tank structure comprises a top cover and side walls. The top cover and the side walls together form a cavity for placing bowls. The top cover comprises one or more top plates. The inner surface of the top cover is configured as a dome-shaped curved surface and is provided with a drainage portion. The drainage portion extends from the top cover to the side walls and is used to drain water droplets to the side walls.

[0009] The top cover of a general dishwasher is a horizontal surface structure. The gravity of the condensed water droplets on the inner surface is greater than the liquid tension and adsorption force, and they directly drip onto the dishes, affecting the washing and drying effects. If the top cover is tilted to a certain angle, or the curved surface reaches a certain curvature, the internal tension and adsorption force of the water droplets can overcome gravity and flow along the slope to the side wall to avoid wetting the dishes. However, a large inclination or curvature of the top cover occupies a large space, affecting the overall volume of the dishwasher. Therefore, a drainage portion is provided on the top cover with a smaller curvature to effectively drain the water droplets to the side wall.

[0010] Furthermore, the drainage portion includes a plurality of raised drainage ribs or recessed drainage grooves, which can make water droplets gather on the drainage ribs or drainage grooves, flow along the drainage ribs or drainage grooves to the side wall, and then flow to the bottom of the dishwasher.

[0011] Furthermore, the top plates intersect to form a vertex, and the drainage portion is arranged in a ray shape on the inner surface of the top plate, extending radially from the vertex to the top end of the side wall.

[0012] The water droplets condensed on the top plate near the drainage part can be adsorbed at the corresponding drainage part, and the vertex is the highest point on the top cover. The drainage part extends to the top of the side wall through the vertex to ensure that the internal water droplets on the top plate will not accumulate on the top cover.

[0013] Furthermore, the drainage portion is arranged in a parallel line shape on the inner side of the top plate and extends toward the top of the side wall. The parallel direction of the drainage portion is not limited, and it can be arranged horizontally, longitudinally, or obliquely.

[0014] Furthermore, the drainage portion is configured to include a ray shape and a parallel line shape, so as to ensure that the water droplets are drained from the top plate to the side wall within the maximum range.

[0015] Furthermore, the guide ribs are spaced apart from adjacent guide ribs by a distance M, where the value of M is 5 to 20 mm. When the guide ribs are arranged as parallel lines, the distances between adjacent guide ribs are consistent. When the guide ribs are arranged as rays, the distance between each guide rib and the bottom edge of the top plate at the intersection is M.

[0016] Furthermore, the guide ribs may be arranged discontinuously, and the breakpoint spacing of the same guide rib is N, N < 10 mm, to avoid too large spacing, condensation of water droplets, gravity being greater than the product of tension and top surface slope, and then dripping from the top surface.

[0017] Furthermore, the width L of the guide rib is 2-5 mm, and the height H is 1-8 mm, so as to destroy the condensation of water droplets on the top plate, so that the water droplets are adsorbed on the guide rib and flow along the guide rib to the side wall.

[0018] Furthermore, the top cover is integrally formed, preferably a plastic part, which is easy to manufacture and is moisture-proof and rust-proof.

[0019] Compared with the prior art, the dishwasher inner tank structure described in the present invention has the following advantages:

[0020] (1) The inner tank structure of a dishwasher described in the present invention can collect and guide water droplets splashed onto the inner tank top cover and water droplets condensed after drying to the side wall through the drainage part, and then flow to the bottom of the dishwasher, thereby ensuring the cleanliness and dryness of the dishes;

[0021] (2) The inner tank structure of a dishwasher described in the present invention is beautiful and easy to manufacture, and the inner tank is waterproof and prevents rust.

[0022] Another object of the present invention is to provide a dishwasher having the above-mentioned dishwasher inner tank structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Embodiment 1, as Figure 1 As shown, a dishwasher inner tank structure includes a top cover 2 and a side wall 1. The top of the side wall 1 is covered and connected with the top cover 2. The top cover 2 and the side wall 1 together form a cavity for placing dishes 3. The top cover 2 includes a top plate 21. The inner surface of the top cover 21 is a dome-shaped curved surface and is provided with a drainage portion 24.

[0040] Furthermore, the drainage portion 24 is arranged in parallel lines, arranged parallel to the inner surface of the top plate 21, and the two ends extend toward the bottom edge 25 of the top plate. The parallel direction of the drainage portion is not limited, and it can be arranged horizontally, longitudinally, or obliquely.

[0041] Furthermore, the guide ribs 241 are spaced apart from adjacent guide ribs 241 by a distance M, where the value of M is 5 to 20 mm. When the guide ribs 241 are arranged as parallel lines, the distances between adjacent guide ribs 241 are consistent. When the guide ribs 241 are arranged as rays, the distance between each guide rib 241 and the bottom edge 25 of the top plate at the intersection is M.

[0042] The guide ribs 241 can be intermittently arranged, and the breakpoint spacing of the same guide rib 241 is N, N < 10mm, to avoid too large spacing, condensation of water droplets, gravity greater than the product of tension and top surface slope, and then dripping from the top surface.

[0043] Furthermore, the width L of the guide rib 241 is 2 to 5 mm, and the height H is 1 to 8 mm, which is convenient for destroying the condensation of water droplets on the top plate, so that the water droplets are adsorbed on the guide rib 241 and flow along the guide rib 241 to the side wall. A point r is randomly selected from the inner surface of the top plate 21, and a tangent is made. A straight line is made perpendicular to the tangent to the surface of the guide rib 241, and intersects the surface of the guide rib 241 at point s. The distance between point r and point s is H, and H is the height of the guide rib 241 at that point.

[0044] Further, by Figure 2 As shown, a straight line is drawn vertically downward from point r and intersects the surface of the guide rib 241 at point q. A tangent is drawn at point q. The angle between the tangent and the horizontal plane is a. The angle between the tangent at point r and the horizontal plane is b, and a≥b. This design allows the water droplets 26 to flow along the guide rib 241 more easily after flowing onto the guide rib 241, and is not easy to drip directly.
