Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0029] Reference below Figure 1-Figure 3 The dishwasher 100 according to the embodiment of the present application is described, and the dishwasher 100 has a cleaning cavity, and the cleaning cavity is used to accommodate tableware, so that the tableware in the cleaning cavity is cleaned by the dishwasher 100. The cleaning cavity can be formed by the inner tank structure of the dishwasher 100.

[0030] According to the present application, the dishwasher 100 includes an electric control box 20, an overflow detection device 31 and a chassis 10. The chassis 10 is arranged at the bottom of the dishwasher 100 to support the dishwasher 100. An installation space is formed between the chassis 10 and the inner tank, and the electric control box 20 and the overflow detection device 31 of the dishwasher 100 can be arranged in the installation space.

[0031] The electric control box 20 and the overflow detection device 31 are electrically connected via a wire harness 40, thereby achieving communication between the electric control box 20 and the overflow detection device 31. Meanwhile, the chassis 10 is formed with a mounting structure, through which the electric control box 20 can be mounted and fixed on the chassis 10.

[0032] Furthermore, the chassis 10 is provided with a mounting portion 11, which is used to install the overflow detection device 31, and the inner bottom surface of the chassis 10 is provided with a supporting portion 12, which is arranged between the electric control box 20 and the overflow detection device 31, and the supporting portion 12 is used to support the wiring harness 40 so as to space the wiring harness 40 from the inner bottom surface of the chassis 10.

[0033] Reference Figure 3 When the electric control box 20 and the overflow detection device 31 are connected through the wiring harness 40, the wiring of the wiring harness 40 will pass through the support portion 12. In order to ensure the reliability of the electrical connection between the electric control box 20 and the overflow detection device 31, the length of the wiring harness 40 is usually greater than the straight-line distance between the connection end of the electric control box 20 and the connection end of the overflow detection device 31, so that the middle part of the wiring harness 40 will maintain a drooping posture. The wiring harness 40 can be supported by the support portion 12 to prevent the middle part of the wiring harness 40 from falling directly on the inner bottom surface of the chassis 10.

[0034] It should be noted that in the related art, the electric control box 20 and the overflow detection device 31 are connected via a wire harness 40, and the wire harness 40 directly contacts the chassis 10. When the dishwasher 100 overflows, the wire harness 40 has the risk of water leakage, which poses a safety hazard.

[0035] When the dishwasher 100 overflows, the water overflowing from the cleaning chamber usually flows into the chassis 10, and the overflow detection device 31 provided on the chassis 10 detects the water accumulation state of the chassis 10 to obtain the overflow state of the dishwasher 100. If the dishwasher 100 overflows, an alarm can be given to the user in time. In other words, the chassis 10 may accumulate water under certain working conditions, thereby posing a risk of the wiring harness 40 being soaked in water, which poses a safety hazard.

[0036] In the present application, a support portion 12 is provided on the chassis 10, and the support portion 12 is arranged between the electric control box 20 and the overflow detection device 31, that is, the support portion 12 is arranged on the routing path of the wire harness 40. When the two ends of the wire harness 40 are respectively connected to the electric control box 20 and the overflow detection device 31, the support portion 12 can support the middle part of the wire harness 40 (that is, the part between the two ends of the wire harness 40) to prevent the wire harness 40 from contacting the inner bottom surface of the chassis 10, thereby preventing the wire harness 40 from contacting the accumulated water in the chassis 10, and avoiding the problem of the wire harness 40 being soaked in water.

[0037] It can be understood that when the amount of water entering the chassis 10 reaches a preset amount, the overflow detection device 31 at the chassis 10 can be triggered, and the wiring harness 40 can be separated from the inner bottom surface of the chassis 10 by the support portion 12. Only when the height of the accumulated water in the chassis 10 reaches the supporting position of the support portion 12, the wiring harness 40 will come into contact with the accumulated water, thereby preventing the wiring harness 40 from being soaked in water as soon as water accumulates in the chassis 10. The response time (such as detection and alarm) for the overflow detection device 31 to detect overflow can be reserved, which can avoid the wiring harness 40 from being soaked in water and improve the safety of the dishwasher 100 when overflow occurs.

[0038] like Figure 3 As shown, in some embodiments of the present application, the height of the electrical connection position between the overflow detection device 31 and the wiring harness 40 relative to the chassis 10 is higher than the height of the support portion 12 relative to the chassis 10, thereby preventing water droplets on the wiring harness 40 from flowing to the connection terminal between the overflow detection device 31 and the wiring harness 40.

[0039] In some embodiments of the present application, the height of the electrical connection position between the electric control box 20 and the wire harness 40 relative to the chassis 10 is higher than the height of the support portion 12 relative to the chassis 10, thereby preventing water droplets on the wire harness 40 from flowing to the connection terminals between the electric control box 20 and the wire harness 40.

[0040] The electrical connection position between the overflow detection device 31 and the wiring harness 40 is also the setting position of the wiring terminal of the overflow detection device 31, and the electrical connection position between the electric control box 20 and the wiring harness 40 is also the setting position of the wiring terminal of the electric control box 20. When the connection terminal of the overflow detection device 31 and the connection terminal of the electric control box 20 are both higher than the support part 12, the wiring harness 40 will maintain a drooping posture in the middle, so that water attached to the wiring harness 40 can drip from the wiring harness 40.

[0041] Reference Figure 3The upper surface of the support portion 12 is configured as a support surface and is used to support the wire harness 40. Since the height positions of the connection terminals of the overflow detection device 31 and the connection terminals of the electric control box 20 are both higher than the support portion 12, the wire harness 40 connected between the overflow detection device 31 and the electric control box 20 can sag and be supported on the support portion 12. When water falls on the wire harness 40, the water can flow along the wire harness 40 to the middle position of the wire harness 40 and drip, thereby preventing the water attached to the wire harness 40 from flowing to the connection terminals to cause a short circuit, further improving the safety and reliability of the electrical connection between the electric control box 20 and the overflow detection device 31.

[0042] In some embodiments of the present application, the mounting portion 11 is disposed in the middle of the chassis 10 , the overflow detection device 31 is mounted on the mounting portion 11 , and the overflow detection device 31 is used to detect a water accumulation state at the chassis 10 .

[0043] It can be understood that the overflow detection device 31 determines whether the dishwasher 100 is in an overflow condition by detecting the amount of water accumulated in the chassis 10. The mounting portion 11 for mounting the overflow detection device 31 is arranged in the middle area of ​​the chassis 10. The water in the chassis 10 can preferentially converge to the middle of the chassis 10 so that the water accumulation state of the chassis 10 can be detected by the overflow detection device 31.

[0044] It should be noted that in order to ensure the accuracy and efficiency of the overflow detection device 31 in detecting the overflow state of the dishwasher 100, a structure for diverting water to the mounting portion 11 (i.e., the area where the overflow detection device 31 is installed) may be provided on the chassis 10, so that the accumulated water in the chassis 10 can quickly converge to the position of the mounting portion 11, so that when the amount of accumulated water in the chassis 10 is small, the overflow detection device 31 can be used to determine that the dishwasher 100 is in an overflow condition.

[0045] In the related art, the dishwasher 100 monitors the overflow state of the dishwasher 100 by setting a water level sensor in the chassis 10 area, which results in a certain amount of accumulated water in the chassis 10 area to trigger the water level sensor, thereby causing the overflow condition detection of the dishwasher 100 to be slow, and when it is determined that the dishwasher 100 is in an overflow condition, a large amount of accumulated water has already existed in the chassis 10, posing a safety hazard of the wiring harness 40 being soaked in water.

[0046] In a further embodiment of the present application, the overflow detection device 31 is provided with a micro switch, which can be triggered when the water level in the chassis 10 reaches a preset position, and the height of the support part 12 relative to the chassis 10 is higher than the height of the contact position of the micro switch relative to the chassis 10.

[0047] When the water level in the bottom pan 10 reaches a preset height, the micro switch can be triggered. When the accumulated water in the bottom pan 10 triggers the micro switch, the overflow detection device 31 detects that the dishwasher 100 is in an overflow condition.

[0048] It can be understood that since the contact position of the micro switch is arranged at a position lower than the height of the support part 12, as the amount of water accumulated in the chassis 10 increases, the water level in the chassis 10 can contact the micro switch before reaching the height of the support part 12, thereby triggering the micro switch first. Before the accumulated water in the chassis 10 contacts the wiring harness 40, the overflow detection device 31 can detect that the dishwasher 100 has overflowed, so that the user can handle it in time, reduce the risk of the wiring harness 40 being soaked in water, and improve the safety of the dishwasher 100 when overflowing.

[0049] Therefore, when the micro switch is triggered by overflow, the water level is lower than the supporting position of the supporting part 12, ensuring that the wiring harness 40 is above the liquid surface, preventing the wiring harness 40 from short-circuiting due to being soaked in water, and improving the safety of the dishwasher 100.

[0050] In some embodiments of the present application, the chassis 10 is provided with a guide surface 14, which is inclined from the outer peripheral side of the chassis 10 to the side of the mounting portion 11, and the guide surface 14 is used to guide the water in the chassis 10 to the side of the mounting portion 11, so that the accumulated water can gather to the side of the mounting portion 11, thereby ensuring the detection effect of the overflow detection device 31.

[0051] It can be understood that the overflow detection device 31 is triggered by detecting that the water level reaches a preset height. If the accumulated water in the chassis 10 is dispersed, it cannot be concentrated at the mounting portion 11, and the microswitch in the overflow detection device 31 cannot be triggered, resulting in more accumulated water in the chassis 10 to trigger the overflow detection device 31, affecting the detection efficiency.

[0052] In the present application, a guide surface 14 is formed on the chassis 10, and the guide surface 14 can guide the water in the chassis 10 to the side of the mounting portion 11, so as to prevent the water in the chassis 10 from being dispersed and retained in different areas of the chassis 10, and the water in the chassis 10 can quickly gather to the side of the mounting portion 11, and then the overflow detection device 31 can determine that the dishwasher 100 is in an overflow condition when there is only a small amount of water accumulated in the chassis 10. Therefore, when the dishwasher 100 leaks and overflows, the water can gather from the outside of the chassis 10 to the mounting portion 11 to trigger the overflow detection device 31.

[0053] It should be noted that the guide surface 14 is also the inner bottom surface of the chassis 10 , and the support portion 12 is used to support the wire harness 40 and to space the wire harness 40 and the guide surface 14 apart.

[0054] In a further embodiment of the present application, the guide surface 14 is constructed as a guide slope, so that the inner bottom surface of the chassis 10 has a certain slope from the outside to the inside, and the overflow alarm device is arranged at the lowest position in the chassis 10 to facilitate the water flow in the chassis 10 to converge to one side of the overflow alarm device.

[0055] The “inner” refers to the side close to the center of the chassis 10 , which is also the side close to the mounting portion 11 ; the “outer” refers to the side close to the peripheral wall of the chassis 10 .

[0056] like Figure 3 As shown, in some embodiments of the present application, the guide surface 14 is provided with a plurality of support portions 12 arranged sequentially from the inside to the outside, and the heights of the plurality of support portions 12 are arranged in an increasing manner from the inside to the outside, thereby ensuring the support effect of the support portion 12 on the wire harness 40. It should be noted that the height of the support portion 12 refers to the height position in the chassis 10, which is also the height position of the support surface for supporting the wire harness.

[0057] It is understandable that the heights of the multiple support portions 12 may be the same or different. Wherein, the guide surface 14 is configured as a guide slope, the support portion 12 is arranged on the guide slope, and the multiple support portions 12 are arranged in the inner and outer directions. At this time, when the protrusion heights of the multiple support portions 12 relative to the guide slope are the same, the heights of the multiple support portions 12 may be arranged to increase from the inside to the outside.

[0058] Reference Figure 2 In some embodiments, the guide surface 14 is configured as a plurality of guide surfaces 14, which are arranged around the mounting portion 11 in the circumferential direction and are all configured as a slope structure that gradually slopes downward from the outside to the inside, so as to ensure the guiding effect of the guide surface 14 on the water flow toward the side of the mounting portion. Figure 2 The arrows on the guide surface 14 are schematic diagrams of the flow path of water under the guidance of the guide surface.

[0059] like Figure 2 As shown, in some embodiments of the present application, the mounting portion 11 is constructed as a mounting groove, which is recessed downward from the inner bottom surface of the chassis 10, and the bottom wall 111 of the mounting groove is set lower than the guide surface 14, and at least part of the overflow detection device 31 is arranged in the mounting groove to trigger the overflow detection device 31 through the accumulated water in the mounting groove.

[0060] Furthermore, when the water in the chassis 10 converges toward one side of the mounting groove under the action of the guide surface, the water in the chassis 10 can be collected in the mounting groove, so as to quickly trigger the overflow detection device 31 arranged in the mounting groove, thereby improving the detection speed. In other words, by cooperating with the guide surface and the mounting groove, the amount of overflow water required to trigger the overflow detection device 31 can be reduced, so that the dishwasher 100 can be detected to be in an overflow state at the early stage of the overflow.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, the support portion 12 is constructed as a support rib, which protrudes upward from the inner bottom surface of the chassis 10. The support rib has a simple structure and a good supporting effect.

[0062] Reference Figure 3 The lower end of the supporting rib is connected to the inner bottom surface of the chassis 10, and the upper end of the supporting rib (i.e., the end away from the inner bottom surface) is used to support the wiring harness 40, so as to set the wiring harness 40 at a distance from the inner bottom surface of the chassis 10 to prevent the wiring harness 40 from being soaked in water.

[0063] Reference Figure 2 In some embodiments, the support ribs are spaced apart from the mounting portion 11 to ensure that the accumulated water in the chassis 10 converges toward one side of the mounting portion 11 .

[0064] It can be understood that in order to ensure the detection effect of the overflow detection device 31, the accumulated water in the chassis 10 will preferentially gather to the side of the mounting portion 11. If the distance between the support rib and the mounting portion 11 is relatively close, the accumulated water on the surface of the support rib away from the mounting portion 11 will not easily flow to the side of the mounting portion 11, thereby affecting the detection effect of the overflow detection device 31.

[0065] In the present application, by spacing the support ribs from the mounting portion 11 , it is possible to prevent the support ribs from obstructing the accumulated water in the chassis 10 from flowing toward the mounting portion 11 , thereby ensuring the detection effect of the overflow detection device 31 .

[0066] In a further embodiment of the present application, the mounting portion 11 is disposed in the middle of the chassis 10, the support ribs extend in an arc shape, and the arc opening faces one side of the mounting portion 11, thereby preventing water from being retained on the surface of the support ribs away from the mounting portion 11, thereby ensuring the detection effect of the overflow detection device 31. The "middle of the chassis 10" refers to the side close to the center of the chassis 10, and is not limited to the center.

[0067] It can be understood that the support ribs extending in an arc shape can guide the water flow. When the accumulated water is located on the side away from the arc-shaped opening, it is more difficult for the accumulated water to stay on the arc surface, so that the accumulated water has the tendency to converge toward the side of the mounting portion 11 along the arc extension direction, thereby reducing the obstruction of the water flow on the support ribs and ensuring that the triggering speed of the overflow detection device 31 is not affected.

[0068] Reference Figure 2In some embodiments, the mounting portion 11 is disposed in the middle area of ​​the chassis 10 and is eccentric to the chassis 10, that is, the mounting portion 11 is not disposed in the center of the chassis 10, that is, the center position of the mounting portion 11 does not coincide with the center position of the chassis 10. It should be noted that the mounting portion 11 is preferably disposed near the center of the chassis 10 so that water flows in multiple directions on the chassis 10 can quickly converge to the mounting portion 11.

[0069] In a further embodiment of the present application, in the vertical projection of the chassis 10, the center position of the mounting portion 11 is arranged to coincide with the center of the support rib, thereby arranging the center of the arc-shaped support rib at the center of the overflow detection device 31, thereby reducing the obstruction of the support rib to the water flow and ensuring the triggering speed of the overflow detection device 31.

[0070] It can be understood that when the water flows along the arc-shaped support ribs to the end position of the support ribs, the water flow is no longer guided by the support ribs and can flow directly to the center position of the mounting portion 11, so as to achieve rapid convergence of the water flow to the position of the mounting portion 11, thereby ensuring the triggering speed of the overflow detection device 31.

[0071] like Figure 2 As shown, in some embodiments of the present application, there are multiple support ribs, and the multiple support ribs are arranged in sequence from the inside to the outside between the electric control box 20 and the overflow detection device 31, so that the wiring harness 40 can be supported by the multiple support ribs, thereby improving the restraining effect of the support ribs on the wiring harness 40 to prevent the wiring harness 40 from contacting the inner bottom surface of the chassis 10.

[0072] Reference Figure 3 Two supporting ribs are provided in the chassis 10, and the two supporting ribs are arranged in sequence from the inside to the outside. That is to say, the two supporting ribs are arranged in sequence in the routing direction of the wire harness 40, so that the middle position of the wire harness 40 (also the drooping part of the wire harness 40) can be supported by the two supporting ribs to prevent the wire harness 40 from falling to a position in contact with the inner bottom surface of the chassis 10.

[0073] It should be noted that, in the description of this application, “plurality” means two or more.

[0074] Reference Figure 2 The two support ribs are both configured to extend in an arc shape, and the extension length of the support rib on the outside is greater than the extension length of the support rib on the inside. After being guided by the support rib on the outside, the water can flow down from both ends thereof and bypass the support rib on the inside to directly flow to the side of the mounting portion 11, thereby reducing the obstruction to the water flow to the side of the support portion 12 and ensuring the triggering speed of the overflow detection device 31.

[0075] like Figure 2As shown, in some embodiments of the present application, the chassis 10 is further provided with a reinforcing rib 13, which is arranged on a side surface of the supporting rib facing the mounting portion 11, and the reinforcing rib 13 is respectively connected to the supporting rib and the inner bottom surface of the chassis 10, so as to improve the structural strength at the supporting rib through the reinforcing rib 13.

[0076] Reference Figure 2 The reinforcing rib 13 is arranged on the side of the supporting rib facing the mounting portion 11 to prevent the reinforcing rib 13 from blocking the flow direction of the water flow. It is understandable that if the reinforcing rib 13 is arranged on the side surface of the supporting rib away from the mounting portion 11, the water flow on the side surface of the supporting rib away from the mounting portion 11 will be blocked by the reinforcing rib 13 and cannot flow from the two ends of the supporting rib to the side of the mounting portion 11 along the extension direction of the supporting rib, thereby causing part of the accumulated water to be retained at the supporting rib, affecting the triggering speed of the overflow detection device 31.

[0077] In some embodiments of the present application, the protruding height of the support rib relative to the inner bottom surface of the chassis 10 is L, and satisfies the relationship: 5mm≤L≤20mm. When the protruding height of the support rib meets the above parameter range, it can play a good supporting role for the wiring harness 40, and the supporting height of the support rib for the wiring harness 40 is not higher than the wiring terminal of the overflow detection device 31 and the wiring terminal of the electric control box 20.

[0078] In some embodiments of the present application, the chassis 10 is further provided with an avoidance groove, and the avoidance groove can be arranged for components above the chassis 10 to avoid. It should be noted that in the dishwasher 100, an installation space is reserved between the chassis 10 and the bottom wall of the inner tank, and components connected to the bottom wall of the inner tank can be suspended above the chassis 10, or extended to the chassis 10 and connected to the chassis 10, such as: a drain pipe, etc., and the above components can be avoided through the avoidance groove.

[0079] Reference Figure 2 The avoidance groove includes a first avoidance groove 151, which is recessed downward from the inner bottom surface of the chassis 10 to form a downwardly recessed groove structure, so that the components installed on the inner tank can be avoided through the first avoidance groove 151 to prevent interference between the components and the chassis 10.

[0080] Furthermore, an upwardly extending annular protrusion 153 is provided at the edge of the first avoidance groove 151 , the annular protrusion 153 is arranged around the opening of the first avoidance groove 151 , and the upper surface of the annular protrusion 153 is arranged higher than the inner bottom surface of the chassis 10 to prevent water in the chassis 10 from leaking at the first avoidance groove 151 .

[0081] In some embodiments of the present application, the avoidance groove further includes a second avoidance groove 152, which is arranged along the thickness direction of the chassis 10 and is used for the pipeline structure to pass through. The pipeline structure can be specifically constructed as a water inlet or drainage structure. Correspondingly, an overflow detection device 31 is also provided in the pipeline structure, and the overflow detection device 31 can also be connected to the electric control box 20 through the wiring harness 40, and the electrical connection end position of the overflow detection device 31 and the wiring harness 40 is higher than the support rib, so as to support the wiring harness 40 through the support rib and keep the wiring harness 40 spaced from the inner bottom surface of the chassis 10.

[0082] In the present application, by providing a support portion 12 in the chassis 10 to support the wire harness 40 through the support portion 12, the wire harness 40 is arranged at a distance from the inner bottom surface of the chassis 10, thereby preventing the wire harness 40 from being soaked in water and improving the safety of the dishwasher 100. At the same time, even if the dishwasher 100 overflows, the overflow detection device 31 can be quickly triggered before the wire harness 40 is soaked in water.

[0083] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the claims and their equivalents.
