Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, and in particular to a dishwasher. Background Technology

[0002] Dishwashers integrate washing, sanitizing, drying, and storage functions, not only changing the traditional hand washing method but also offering advantages such as attractive appearance, ease of use, time and labor saving, and hygienic cleaning, making them increasingly popular among consumers. The working principle of a dishwasher is that a motor drives a washing pump to spray detergent under pressure from a spray nozzle, forming a dense three-dimensional hot water stream. The spray nozzle rotates due to the reaction force of the sprayed water, evenly spraying the detergent onto the dishes inside the dishwasher, providing a three-dimensional spray rinse and scrub.

[0003] Prior art CN210990112U discloses a dishwasher, including an inner tub. A spray nozzle mounting base is provided on the bottom of the inner tub, and an overflow channel is fixed on the spray nozzle mounting base. The inner tub communicates with a dishwasher base plate located below the inner tub through the overflow channel. An alarm device is provided on the dishwasher base plate. When the water level on the dishwasher base plate reaches a preset level, the alarm device on the dishwasher base plate is triggered, and the alarm device emits an alarm signal or cuts off the water supply, thereby effectively preventing the dishwasher from overflowing.

[0004] In existing technology, an overflow port is opened on the side wall of the overflow channel. The overflow port is located inside the inner tank. A baffle plate is set on the front side of the bottom of the inner tank. The height between the overflow port and the bottom of the inner tank is lower than the height of the baffle plate. Although the height of the baffle plate is set to be greater than the height of the overflow port, so that water higher than the overflow port is blocked by the baffle plate and prevented from overflowing from the inside of the inner tank, during the use of the dishwasher, the water in the inner tank has a certain impact. The water will splash after the impact. When the water splashes onto the upper part of the baffle plate, the water can easily overflow from the gap between the baffle plate and the bottom plate. Utility Model Content

[0005] The purpose of this invention is to provide a dishwasher that solves the problem of water overflowing from the gap between the baffle and the bottom plate under the impact of the water, reduces the possibility of water overflowing from the baffle and the bottom plate, and thus improves the sealing effect between the bottom of the front side of the inner tank and the bottom plate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dishwasher includes a body, an inner tub and a door. One side of the inner tub has an opening, and the door opens or closes the opening. A sealing strip is provided on the lower side of the door. The sealing strip includes an mounting part, a connecting part, and a sealing part. The mounting part is fixedly connected to the door. The connecting part connects between the mounting part and the sealing part. The sealing part extends away from the connecting part and towards the edge of the opening, sealing against the edge of the opening. A flange extending in the opposite direction is provided on the lower side of the door, forming a mounting groove between the flange and the door for the mounting part to insert. The connecting part extends along the insertion direction of the mounting part and forms a U-shaped structure with the mounting part to clamp the flange. The connecting part has a stress-bearing area. By squeezing the stress-bearing area, the flange is deformed, pressing and fixing the sealing strip, and deforming the connecting part, thereby making the sealing part more tightly adhere to the edge of the opening to improve the sealing performance after the door is closed.

[0007] After adopting the above technical solution, this utility model has the following advantages: The dishwasher is configured with an inner tub and a door. The inner tub has an opening, and the opening and closing of the door allows for easy placement of dishes to be cleaned or removal of cleaned dishes. A sealing strip is installed on the lower side of the door, and the sealing strip is composed of three parts: an installation part, a connecting part, and a sealing part. The sealing part is installed on the lower side of the door through the installation part, facilitating the installation and fixing of the sealing strip. The connecting part and the installation part form a U-shaped structure, and the installation part and the connecting part clamp the flange, improving the stability of the sealing strip after installation. The installation part is located on the lower side of the door. After the door and the flange are positioned together, the flange deforms by squeezing the stress area. This deformation presses against the mounting part, stabilizing the sealing strip and preventing the mounting part from sliding upwards during the sealing process, which would affect the stability of the sealing strip. The stress on the stress area causes the flange to deform, generating holding and pressing forces on the sealing strip, further improving its stability after installation. Once the mounting part and connecting part are stable, the contact force between the sealing part and the opening edge is increased, improving the sealing effect and reducing the possibility of water overflowing from the opening edge. Squeezing the stress area also deforms the connecting part, causing it to deform further, making the sealing part fit even tighter against the opening edge and improving the seal when the door is closed.

[0008] Furthermore, multiple stress-bearing areas are provided along the length of the sealing strip, and the connecting part of at least one stress-bearing area is a thin sheet structure. After the connecting part is deformed, the sealing part fits more tightly against the edge of the opening.

[0009] By adopting the aforementioned technical solution, multiple stress-bearing areas are set on the connecting part, increasing the number of deformations caused by the flange after the connecting part is squeezed, thereby increasing the holding force and clamping force of the installation part and improving the stability of the sealing strip after installation; the connecting part of at least one stress-bearing area is set as a thin sheet structure, increasing the deformation of the connecting part after squeezing, further improving the holding force and clamping force generated after deformation, and further improving the stability of the sealing strip.

[0010] Furthermore, the sealing strip has stress-bearing areas at both ends, and the connection part of the stress-bearing areas is a thin sheet structure.

[0011] By adopting the aforementioned technical solution, two of the multiple stress areas are located at both ends of the sealing strip, and the connection part of the stress areas at both ends is a thin sheet structure, which improves the stability of the two ends of the sealing strip after installation and reduces the possibility of the two ends of the sealing strip lifting up.

[0012] Furthermore, the thickness of the connecting portion is less than the thickness of the mounting portion and less than the thickness of the sealing portion.

[0013] By adopting the aforementioned technical solution, the thickness of the connecting part is set to be less than the thickness of the mounting part and the sealing part, so as to ensure that the connecting part deforms when the pressure area is compressed, thereby ensuring that the flange deforms and generates a retaining force on the mounting part.

[0014] Furthermore, the thickness of the connecting portion is 0.8mm to 1.5mm.

[0015] By adopting the aforementioned technical solution, the thickness of the connecting part is set to 0.8mm to 1.5mm, so that the connecting part deforms when it is squeezed, and the thickness of the connecting part is not too small, which would cause cracks in the connecting part when squeezed, thus reducing the possibility of damage to the connecting part when squeezed.

[0016] Furthermore, the sealing part includes a plurality of sealing ribs arranged side by side, with one end of the sealing rib away from the connecting part fitting against the edge of the opening.

[0017] Using the aforementioned technical solution, the sealing part is configured with multiple sealing ribs arranged side by side. The end of the sealing rib away from the connecting part fits against the edge of the inner liner opening, thereby achieving the effect of sealing and preventing water overflow. The arrangement of multiple sealing ribs means that when the sealing rib abuts against the edge of the inner liner opening, it can be one sealing rib or multiple sealing ribs abutting. When multiple sealing ribs abut, the sealing and water overflow prevention effect is improved.

[0018] Furthermore, the spacing between two adjacent sealing ribs increases along the extension direction of the sealing ribs.

[0019] By adopting the aforementioned technical solution, the spacing between two adjacent sealing ribs is set to increase with the extension direction of the sealing ribs, so as to avoid the possibility of multiple sealing ribs forming when they abut against the edge of the inner liner opening and affecting each other, thus ensuring the sealing and overflow prevention effect of the sealing ribs at the edge of the inner liner opening.

[0020] Furthermore, the mounting part is provided with multiple raised ribs on the side facing the machine door to enhance the fixing effect of the mounting part, and the raised ribs are closely attached to the machine door.

[0021] Using the aforementioned technical solution, the mounting part is provided with multiple raised ribs. These ribs are close to the machine door, increasing the friction between the mounting part and the machine door. When the sealing strip abuts against the edge of the inner tank opening, the raised ribs prevent the mounting part from sliding upward and disengaging from the flange, thereby improving the holding force of the mounting part, improving the stability of the sealing strip, and further improving the sealing and water-proofing effect of the sealing strip.

[0022] Furthermore, the bottom of the door is hinged to the body or inner liner, and the inner liner has an upwardly extending folded edge on the front side of the lower edge of the opening, with the top of the folded edge not lower than the sealing strip.

[0023] Using the aforementioned technical solution, the bottom of the door is hinged to the machine body or inner tank, making it easy to rotate and open the machine; a folded edge is provided on the front side of the lower edge of the inner tank opening, which extends upward to expand the edge range of the inner tank opening and ensure that the sealing strip fits and seals the opening of the inner tank; the upward extension of the folded edge can also prevent water from overflowing from the inner tank; the top of the folded edge is not lower than the sealing strip to ensure the sealing and water-proof effect of the sealing strip.

[0024] Furthermore, the sealing part is fitted and sealed to the bottom of the folded edge.

[0025] By adopting the aforementioned technical solution, after the folded edge is set, the sealing part fits and seals with the bottom of the folded edge, ensuring the sealing effect between the sealing part and the folded edge and reducing the possibility of water overflowing from the opening of the inner liner.

[0036] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0037] like Figure 1 As shown, this utility model provides a dishwasher, including a body, an inner tub 1 and a door 2. An opening 11 is provided on one side of the inner tub 1, and the door 2 opens or closes the opening 11. Figure 3 As shown, a sealing strip 3 is provided on the lower side of the machine door 2, such as... Figure 3As shown, the sealing strip 3 includes a mounting part 31, a connecting part 32, and a sealing part 33. The mounting part 31 is fixedly connected to the machine door 2. The connecting part 32 is connected between the mounting part 31 and the sealing part 33. The sealing part 33 extends away from the connecting part 32 and towards the edge of the opening 11, and the sealing part 33 fits and seals against the edge of the opening 11. The lower side of the machine door 2 is provided with a flange 21 extending in the opposite direction. A mounting groove 22 is formed between the flange 21 and the machine door 2 for the mounting part 31 to be inserted. The connecting part 32 extends along the insertion direction of the mounting part 31 and forms a U-shaped structure with the mounting part 31 to clamp the flange 21. Figure 4 As shown, the connecting part 32 has a force-bearing area 321. After the mounting part 31 is inserted into the mounting groove 22, the force-bearing area 321 on the connecting part 32 is pressed, such as... Figure 5 and Figure 6 As shown, the flange 21 is deformed to press and fix the sealing strip 3; after the flange 21 is deformed, the deformed position abuts against the mounting part 31 towards the center of the mounting groove 22, increasing the friction between the mounting part 31 and the groove wall of the mounting groove 22, thereby improving the holding force of the flange 21 and the door 2 on the mounting part 31, and the deformed flange 21 and the door 2 generate a clamping force on the mounting part 31, thereby improving the stability of the sealing strip 3 after installation; as Figure 6 As shown, when the stressed area 321 is squeezed, the connecting part 32 also deforms, causing the lower connecting part 32 to drive the sealing part 33 to deform outward, making the sealing part 33 more tightly attached to the edge of the opening 11, thereby improving the sealing performance of the door 2 after it is closed and improving the sealing and anti-overflow effect of the sealing part 33. Compared with the water baffle of the prior art, the anti-overflow effect achieved by the sealing part 33 being tightly attached to the edge of the opening 11 can better prevent water in the inner tank 1 from overflowing from the opening 11 of the inner tank 1, thus improving the sealing performance of the door 2 after it is closed. When the stressed area 321 is squeezed, a rivet gun is usually used to generate an impact force on the stressed area 321 to squeeze the stressed area 321, causing the connecting part 32 and the flange 21 to deform and press the mounting part 31.

[0038] In this embodiment, as Figure 4 As shown, multiple stress-bearing areas 321 are provided along the length of the sealing strip 3, and the connecting part 32 at one stress-bearing area 321 is provided as a thin sheet structure. The thin sheet structure reduces the thickness of the connecting part 32 in the stress-bearing area 321, weakens the obstruction of the connecting part 32 to the rivet gun, increases the deformation of the flange 21 and the mounting part 31, and improves the holding force of the flange 21 and the door 2 on the mounting part 31, thereby improving the stability of the sealing strip 3 after installation. Alternatively, the connecting parts 32 at multiple stress-bearing areas 321 can be provided as thin sheet structures, increasing the holding force at multiple positions on the mounting part 31, thereby improving the stability of the sealing strip 3 after installation.

[0039] To further improve the stability of the sealing strip 3 after installation, both ends of the sealing strip 3 have a stress area 321, and the connecting part 32 of the stress area 321 at both ends is a thin sheet structure, which increases the deformation of the corresponding flange 21 at both ends of the sealing strip 3, improves the stability of both ends of the connecting part 32, and reduces the impact on the stability of the connecting part 32 when the stress area 321 in the middle is squeezed.

[0040] By setting the thin sheet structure, the deformation of the flange 21 and the mounting part 31 is increased, which improves the holding force of the mounting part 31 in the mounting groove 22. After the holding force is increased, the sealing strip 3 can be manufactured using a material with lower hardness, which improves the deformation reaction force of the sealing part 33 when the door 2 is closed, thereby reducing the upward lifting amount of the door 2 after it is closed, expanding the activity gap above the door 2, and ultimately improving the user's operating experience of opening and closing the door 2.

[0041] In another embodiment, such as Figure 3 As shown, to ensure that the flange 21 deforms when the pressure area 321 is compressed, the thickness of the connecting part 32 is set to be less than the thickness of the mounting part 31 and less than the thickness of the sealing part 33. When the rivet gun is pressed into the pressure area 321, it ensures that the flange 21 deforms, thereby ensuring that the flange 21 generates a holding force on the mounting part 31 after deformation, improving the stability of the sealing strip 3 after installation. Furthermore, the thickness of the connecting part 32 is set in the range of 0.8mm to 1.5mm to ensure that the connecting part 32 deforms after compression, while avoiding the possibility of the connecting part 32 breaking due to excessively small thickness.

[0042] To improve the stability of the mounting section 31 in the mounting slot 22, such as Figure 6 As shown, the mounting part 31 is provided with a plurality of protruding ribs 311 on the side facing the door 2 to increase the fixing effect of the mounting part 31. After the mounting part 31 is installed in the mounting groove 22, the protruding ribs 311 are close to the door 2. The protruding ribs 311 increase the friction between the mounting part 31 and the door 2, thereby improving the stability of the mounting part 31 in the mounting groove 22.

[0043] To improve the sealing effect of the sealing part 33 after it fits into the opening 11 of the inner liner 1, such as Figure 7 As shown, the sealing part 33 includes multiple sealing ribs 331 arranged side by side. When the sealing part 33 is fitted to the edge of the opening 11 of the inner liner 1, the sealing rib 331, with its end away from the connecting part 32, fits against the edge of the opening 11. Specifically, one sealing rib 331 may fit against the edge of the opening 11 of the inner liner 1. After fitting, it prevents water inside the inner liner 1 from overflowing from the gap between the lower side of the door 2 and the edge of the opening 11 of the inner liner 1. Alternatively, multiple sealing ribs 331 may simultaneously abut against the edge of the opening 11 of the inner liner 1 to further improve the sealing and overflow prevention effect.

[0044] In this embodiment, as Figure 7 As shown, the distance between two adjacent sealing ribs 331 increases with the extension direction of the sealing ribs 331. When the sealing ribs 331 are close to the edge of the opening 11 of the inner liner 1, the ends of the sealing ribs 331 will deform, increasing the distance between two adjacent sealing ribs 331 with the extension direction. This reduces the possibility of interference between the sealing ribs 331 after deformation, which may affect the sealing effect, thereby improving the sealing and water-proofing effect.

[0045] In another embodiment, such as Figure 1 and Figure 7 As shown, the bottom of the door 2 is hinged to the body. When opening or closing the door 2, hold the top of the door 2 and pull it outward, causing the bottom of the door 2 to rotate relative to the body, thereby causing the door 2 to flip open. The bottom of the door 2 can also be hinged to the inner tank 1. The inner tank 1 has a folded edge 12 on the front side of the lower edge of the opening 11. The folded edge 12 is extended upward at an angle so that it can be used to block water and reduce the possibility of water overflowing from the opening 11 of the inner tank 1. Specifically, when the folded edge 12 is set, the top of the folded edge 12 is not lower than the sealing strip 3, so that the sealing part 33 fits and seals with the bottom of the folded edge 12, so that the folded edge 12 blocks water and fits with the sealing part 33 to further prevent water overflow.

[0046] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
