Description

Technical Field

[0001] This utility model belongs to the field of dishwasher technology, and more specifically, it relates to an overflow structure for a dishwasher and a dishwasher. Background Technology

[0002] As a water-using appliance, dishwashers require water to enter their inner tub for the spray system to clean the dishes. The water level is a crucial control parameter during operation. Insufficient water hinders the spray system's operation, affecting cleaning effectiveness. Conversely, excessive water exceeding the dishwasher's threshold causes overflow. Dishwasher overflow occurs when too much water enters the tub, exceeding its capacity and overflowing. To prevent overflow, dishwashers typically have an overflow system. This allows excess water to drain into the base, triggering an alarm on the overflow protection device.

[0003] However, in related technologies, dishwasher overflow outlets are usually located on both sides of the front baffle of the inner tub. During dishwasher operation, water splashed onto the door panel flows down the sides of the door panel into the overflow outlet, and then enters the dishwasher base through the overflow channel. If there is no overflow fault in the dishwasher's washing chamber, the overflow protection device in the base is triggered, generating a false alarm, i.e., a false overflow phenomenon occurs. Utility Model Content

[0004] To address the issue of water splashing onto the door panel flowing down the sides of the door panel into the overflow outlet, triggering a false alarm from the overflow protection device in the base even when there is no overflow in the dishwasher's washing chamber, the purpose of this invention is to provide an overflow structure for a dishwasher. The overflow structure includes an inner tub, an overflow outlet on the inner tub, and a water receiving plate located below the overflow outlet; the water receiving plate has a water inlet, and a flow channel is formed between the water receiving plate and the inner tub; wherein the inner tub includes a front baffle, and the overflow outlet is located in the middle of the front baffle.

[0005] Compared to existing technologies, the technical benefits of this solution are as follows: By adjusting the overflow outlet from the sides of the inner tub's front baffle to its central position, water splashed onto the door panel flows down along the sides and cannot enter the overflow outlet in the center of the inner tub's front baffle. Instead, it continues to flow downwards to the bottom of the inner tub for washing circulation or drainage. This effectively avoids the overflow protection device from triggering a false alarm when there is no water leakage in the water system or the water inlet sensor is not malfunctioning, thus improving the accuracy of the dishwasher's overflow alarm.

[0006] Furthermore, a water-guiding flange is provided at the overflow outlet.

[0007] Compared with existing technologies, the technical effect achieved by adopting this technical solution is that the water guide flange can divert the water overflowing from the overflow port into the guide channel.

[0008] Furthermore, the water guide flange and the front baffle are integrally formed.

[0009] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting the water guide flange and the front baffle to be integrally formed, on the one hand, it can provide higher structural strength and resist water flow impact deformation; on the other hand, it can eliminate seams and prevent overflow water from leaking from the connection between the water guide flange and the front baffle, thus affecting the normal operation of the dishwasher.

[0010] Furthermore, the flow channel includes an arc-shaped section for storing water and a flow-guiding section for draining water into the dishwasher base; wherein the arc-shaped section is located above the flow-guiding section.

[0011] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting an arc-shaped section at the front end of the guide section for water storage, splashing droplets can be temporarily stored, preventing direct discharge from the guide channel from falsely triggering the overflow alarm. Even if a small amount of splashing droplets flows along the door panel into the overflow port in the middle, they will not directly enter the water tray on the dishwasher base along the guide channel, causing the water level to rise. Instead, they will remain in the arc-shaped section at the front end of the guide section, thereby further improving the accuracy of the dishwasher's overflow alarm.

[0012] Furthermore, the flow channel also includes a drainage section, which is located at the end of the flow channel away from the arc-shaped section; wherein, the width of the drainage section gradually decreases along the direction away from the flow channel.

[0013] Furthermore, two water guide ribs are inclinedly set at the bottom of the flow channel to form a V-shaped drainage section; the bottom arcs of the two water guide ribs are connected to form an arc-shaped drainage nozzle.

[0014] Furthermore, the water receiving plate is also equipped with multiple reinforcing ribs, which are evenly distributed on both sides of the flow channel.

[0015] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting multiple reinforcing ribs on the water receiving plate, the structural strength and deformation resistance of the water receiving plate can be improved, preventing deformation of the water receiving plate from causing the diversion channel to shift or leak, and ensuring the stability of the drainage path.

[0016] Furthermore, a filter element is installed at the overflow outlet.

[0017] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting a filter at the overflow outlet, it can filter out residues and prevent food residues from clogging the overflow outlet, thus avoiding problems such as slow drainage and drainage delay.

[0018] Furthermore, the overflow port is a square opening, and the opening width of the overflow port is smaller than the opening width of the water inlet.

[0019] This utility model provides a dishwasher that includes the overflow structure of any of the dishwashers described above and can solve the same problem. To avoid repetition, it will not be described again here. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0031] See Figure 1 This is a schematic diagram of the overflow structure of a dishwasher provided by this utility model. Combined with... Figures 1 to 8 The dishwasher's overflow structure includes an inner tub 10, an overflow port 20 on the inner tub 10, and a water receiving plate 40 located below the overflow port. The inner tub 10 includes a front baffle 11, and the overflow port 20 is located in the middle of the front baffle 11. For example, when the dishwasher door is closed, both sides of the door are sealed to the side walls of the dishwasher, and the bottom of the door is sealed to the front baffle 11.

[0032] Specifically, the water receiving plate 40 is provided with a water inlet 41, and two baffles 42 integrally formed with the water receiving plate are provided on both sides of the water receiving plate 40, forming a flow guiding channel 50 between the two baffles 42. Among them, the two baffles 42 are the side walls of the flow guiding channel 50, the water receiving plate 40 is the bottom wall of the flow guiding channel 50, and the bottom end face of the inner liner 10 forms the top wall of the flow guiding channel 50.

[0033] It should be noted that during dishwasher operation, when the washing water sprayed from the spray arms splashes onto the door panel, it easily flows down the sides of the door panel in streams. Since the overflow port 20 is located on both sides of the front baffle 11 of the inner tub 10 in related technologies, the washing water flowing down the sides of the door panel can easily enter the overflow channel through the overflow port 20, causing the water level in the dishwasher base to rise. This triggers the overflow float of the overflow protection device, thus pre-detecting an overflow alarm if there is no water leakage in the water system or if the water inlet sensor is not malfunctioning.

[0034] By adjusting the position of the overflow outlet 20 from both sides of the front baffle 11 of the inner tub 10 to its central position within the front baffle 11, the water splashing onto the door panel is avoided. Water splashed onto the door panel flows down along both sides and does not enter the overflow outlet 20 in the center of the front baffle 11. Instead, it continues to flow down to the bottom of the inner tub 10 for washing circulation or drainage. This effectively prevents the overflow protection device from triggering a false alarm when there is no leakage in the water system or a faulty water inlet sensor, thus improving the accuracy of the dishwasher's overflow alarm.

[0035] Furthermore, a water-guiding flange 30 is provided at the overflow port 20. For example, the outer edge of the front baffle 11 of the inner tank 10 at the overflow port 20 extends obliquely towards the guide channel 50, forming the water-guiding flange 30. The water-guiding flange 30 extends into the water inlet 41, guiding the water overflowing from the overflow port 20 into the guide channel 50. When the water level in the washing chamber is too high, the overflow water discharged from the overflow port 20 will enter the guide channel 50 from the water inlet 41, and then flow into the dishwasher base through the guide channel 50.

[0036] Preferably, the water-guiding flange 30 and the front baffle 11 are integrally formed. By making the water-guiding flange 30 and the front baffle 11 integrally formed, on the one hand, it can provide higher structural strength and resist deformation caused by water flow impact; on the other hand, it can eliminate seams and prevent overflow water from leaking from the connection between the root of the water-guiding flange 30 and the front baffle 11, thus affecting the normal operation of the dishwasher.

[0037] Furthermore, the flow channel 50 includes an arc-shaped section 51 for storing water, a flow guide section 52 for draining water into the dishwasher base, and a drain section 53 for draining overflow water to the dishwasher base. The arc-shaped section 51 is located above the flow guide section 52, and the drain section 53 is located at the end of the flow guide section 52 away from the arc-shaped section 51. Water overflowing from the overflow port 20 enters the flow channel 50 from the water inlet 41 and flows sequentially through the arc-shaped section 51, the flow guide section 52, and the drain section 53.

[0038] It should be noted that by setting an arc-shaped section 51 for water storage at the front end of the guide section 52, splashed droplets can be temporarily stored, preventing the guide channel 50 from directly discharging and falsely triggering the overflow alarm. In a specific embodiment, even if a small amount of splashed droplets flow into the overflow port 20 in the middle along the door panel, they will not directly enter the water tray of the dishwasher base along the guide channel 50, causing the water level to rise. Instead, they will remain in the arc-shaped section 51 at the front end of the guide section 52, thereby further improving the accuracy of the dishwasher's overflow alarm.

[0039] Furthermore, the width of the drainage section 53 gradually decreases along the direction away from the guide section 52, which can collect water flow and accelerate the drainage velocity. For example, two guide ribs 531 are inclinedly set at the bottom of the guide channel 50 to form a V-shaped drainage section 53; the bottom arcs of the two guide ribs 531 are connected to form an arc-shaped drain nozzle 532. By setting the bottom arc transition of the two guide ribs 531, the arc-shaped drain nozzle 532 can eliminate the dead corners of water accumulation in the drainage section 53 and prevent water residue from accumulating at the bottom of the guide channel 50.

[0040] Furthermore, the water receiving plate 40 is also provided with multiple reinforcing ribs 43, which are evenly distributed on both sides of the flow guiding channel 50. By providing multiple reinforcing ribs 43 on the water receiving plate 40, the structural strength and deformation resistance of the water receiving plate 40 can be improved, preventing deformation of the water receiving plate 40 from causing the flow guiding channel 50 to shift, and ensuring the stability of the drainage path. For example, the multiple reinforcing ribs 43 form a grid-like support on the inner wall of the water receiving plate 40.

[0041] Furthermore, a filter element is provided at the overflow outlet 20. For example, the filter element is a mesh grille. This mesh grille can be fixedly installed at the overflow outlet 20, or it can be installed at the overflow outlet 20 in a detachable manner such as magnetic attraction; there are no restrictions here. By setting a filter element at the overflow outlet 20, it can filter out residues and prevent food residues from clogging the overflow outlet 20, thus avoiding problems such as slow drainage and drainage delays.

[0042] Furthermore, the overflow port 20 is a square opening, and the opening width of the overflow port 20 is smaller than the opening width of the water inlet 41. When the inner tank 10 overflows, the water inlet 41 can quickly collect all the water overflowing from the overflow port 20 into the guide channel 50, and guide the water overflowing from the inner tank 10 into the water tray at the bottom of the dishwasher.
