Description

Technical field

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

[0002] An existing dishwasher includes a base and an inner tank. When a malfunction occurs, the dishwasher may have abnormal water supply, resulting in leakage in the inner tank, leakage when the pipe ruptures, and condensation water leakage. In order to prevent water from flowing directly onto the ground, it is necessary to collect the leaked or overflowed water. To this end, the base is provided with a water collection area for collecting the above-mentioned leakage. If the overflow or leakage of the dishwasher cannot be quickly discovered and controlled, the water in the water collection area may flow out of the base and then flow to the ground, posing a great safety threat to the floor, kitchen utensils and even the home. In order to detect leakage problems in time, an overflow detection structure is provided in the existing water collection area. When the water level in the water collection area reaches the detection level, the overflow detection structure is triggered to complete the alarm action, so that the user can check the leakage problem in time.

[0003] It can be seen that the correct installation and normal operation of the overflow detection structure are very important for detecting overflow and leakage problems. For this reason, existing dishwashers usually conduct a full inspection of the overflow detection structure during the manufacturing process. Since the overflow protection structure in existing dishwasher technology is set at the middle and rear side of the base, the machine needs to be disassembled for inspection. Therefore, when the function test is carried out after the entire machine is completed, only a small amount of water injection test can be carried out, and a full inspection cannot be achieved. In addition, when a fault occurs at the user's home, it is also necessary to first check whether the overflow detection structure is faulty. However, when checking the fault of the overflow detection structure, the machine still needs to be disassembled for confirmation, which is extremely inconvenient, thereby reducing the efficiency of the functional inspection of the overflow detection structure. [Utility Model Content]

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the existing technology and provide a dishwasher that can detect the overflow detection structure in the complete machine state, thereby reducing time costs and improving the efficiency of functional detection during production and after-sales maintenance.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A dishwasher comprises a base and an inner tank, wherein the inner tank is provided with an overflow port, the base is provided with a water collection area for collecting leaked water, an overflow detection structure is provided in the water collection area, and the overflow detection structure is triggered when the water level in the water collection area reaches a detection water level, and a detection port is provided on the side wall of the base, which is higher than the detection water level, the detection port is provided corresponding to the overflow detection structure and is used to pass a detection tool through the detection port, so that the detection tool can detect whether the overflow detection structure can be triggered, and whether the overflow detection structure is installed in place by visual inspection through the detection port.

[0007] The side wall of the base in the utility model is provided with a detection port which is higher than the detection water level. Such a design can prevent the water in the water collection area from flowing to the outside of the base through the detection port when the amount of water has not yet reached the detection water level, thereby ensuring that the subsequent overflow detection structure can be triggered after the water level in the water collection area reaches the detection water level; and the detection port is arranged corresponding to the overflow detection structure and is used to allow the detection tool to pass through. In this way, during detection, the detection tool can pass through the detection port and extend into the water collection area to detect whether the overflow detection structure can be triggered. At the same time, the inspection personnel can also observe through the detection port whether the overflow detection structure is missing and whether it is installed in place, so as to realize the full inspection of the overflow detection structure without disassembling the machine. That is, the dishwasher in the utility model can realize the inspection of the overflow detection structure in the state of the whole machine, thereby reducing the time cost and improving the functional inspection efficiency during production and after-sales maintenance.

[0008] In the above-mentioned dishwasher, the side walls of the base include an outer wall and an inner wall. Part of the outer wall includes a vertical section and a guide section formed by an inward bend at the bottom of the vertical section. The guide section extends downward and connects to the inner wall. The detection port is provided on the inner wall, and the guide section is used to guide the detection tool through the detection port. This design can increase the structural strength of the base side walls by providing the outer wall and the inner wall to ensure the integrity of the base structure. In addition, the guide section can guide the detection tool to be smoothly inserted into the detection port, so that the detection tool can be inserted into the area to be inspected, thereby improving detection efficiency. It also serves as a visual guide to facilitate observation of the overflow detection structure. Finally, no additional sliders or inclined tops are required during the injection molding of the base, which conforms to the main demolding direction, simple molding, and low cost.

[0009] In the above-mentioned dishwasher, the inner sidewall includes an outwardly bent portion, comprising a first bent section connected to the guide section and a second bent section connected to the bottom of the first bent section. The second bent section extends inward and downward at an angle to guide the insertion of a detection tool, and the detection port is located at the junction of the first and second bent sections. This design further supports and limits the detection tool through the second bent section, guiding it into the area to be inspected, thereby enhancing the guidance effect on the insertion direction of the detection tool. Furthermore, it also conforms to the main mold stripping direction, is simple to form, and is low in cost.

[0010] In the above-mentioned dishwasher, the angle between the guide section and the horizontal plane is between 20° and 60°. This design allows personnel to observe the overflow detection structure through the detection port while crouching, without having to lie on the ground for observation, thereby improving the feasibility of observation and detection.

[0011] In the above-mentioned dishwasher, the bottom of the inner tank is provided with electronic components located above a water collection area, and the sidewall of the base is provided with a drain port connected to the water collection area, the drain port being located below the electronic components. This design allows the water in the water collection area to be promptly drained through the drain port when a large amount of water is present, thereby preventing damage to the electronic components caused by water contact.

[0012] In the above dishwasher, the lowest point of the detection port is not lower than the lowest point of the drainage port. This design can prevent water from flowing out of the detection port when the amount of water in the water collection area is small.

[0013] In the above-mentioned dishwasher, the side walls of the base include a front side wall, the detection port is provided on the front side wall, and the overflow detection structure is disposed proximate to the front side wall. With this design, when the dishwasher is embedded in a kitchen cabinet, since the front side wall is exposed to the outside, the detection port is provided on the front side wall, facilitating visual inspection and inspection using inspection tools without disassembling the cabinet. Furthermore, if a overflow occurs, water can flow out of the front detection port, allowing the user to quickly detect the overflow.

[0014] In the above-mentioned dishwasher, the overflow detection structure includes two electrode probes installed at intervals in the water collection area. When the water level in the water collection area reaches the detection water level, the two electrode probes are turned on, and the detection port is set corresponding to the two electrode probes at the same time; or the number of detection ports is two, and the two detection ports are set corresponding to the two electrode probes respectively.

[0015] In the above-mentioned dishwasher, there are two detection ports, one corresponding to each of the two electrode probes. The aperture of the detection port ranges from 1mm to 5.6mm. This design not only prevents infants and children from inserting their fingers into the detection port, which could cause unsafe situations, but also avoids the detection port being too large and affecting the appearance, while ensuring that the detection tool can be inserted into the detection port.

[0016] In the above dishwasher, the overflow detection structure is a micro switch, and a float is provided in the water collection area, which floats up and down with the water level in the water collection area. When the water level in the water collection area reaches the detection water level, the float triggers the micro switch.

[0017] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0027] Example 1

[0028] like Figures 1 to 5As shown, the dishwasher in this embodiment includes a base 100 and an inner tank (not shown in the figure), the inner tank is provided with an overflow port, and the bottom wall of the base 100 is provided with a water collection area 110 for collecting leaked water. An overflow detection structure 200 is provided in the water collection area 110. When the water level in the water collection area 110 reaches the detection water level H1, the overflow detection structure 200 is triggered. The overflow detection structure 200 is connected to the control part of the dishwasher. After the overflow detection structure 200 is triggered, a signal is sent to the control part, and the control part sends an alarm information according to the signal. A detection port 120 is provided on the side wall of the base 100, which is higher than the detection water level H1. This design can prevent the water in the water collection area 110 from flowing to the outside of the base 100 through the detection port 120 when the water level has not yet reached the detection water level H1, thereby ensuring that the subsequent overflow detection structure 200 can be triggered after the water level in the water collection area 110 reaches the detection water level H1; and the detection port 120 is set corresponding to the overflow detection structure 200 and the detection port 120 is used to allow the detection tool to pass through, so that during the detection, the detection tool can pass through the detection The port 120 extends into the water collection area 110 to detect whether the overflow detection structure 200 can be triggered. At the same time, the inspection personnel can also observe whether the overflow detection structure 200 is missing and whether it is installed in place through the inspection port 120, so as to realize a full inspection of the overflow detection structure 200 without disassembling the machine. That is, the dishwasher in this embodiment can realize the inspection of the overflow detection structure 200 in the state of the whole machine, thereby reducing the time cost and improving the efficiency of functional inspection during production and after-sales maintenance.

[0029] Specifically, the overflow detection structure 200 in this embodiment includes two electrode probes 210 installed at intervals in the water collection area 110. A mounting portion 111 is provided in the water collection area 110, and two vertically extending mounting holes 1110 are provided on the mounting portion 111. The two electrode probes 210 are respectively clamped and fixed in the two mounting holes 1110. The lower ends of the two electrode probes 210 are flush or staggered up and down. Preferably, the lower ends of the two electrode probes 210 are flush. At this time, the height of the lower ends of the two electrode probes 210 is the detected water level H1. The upper ends of the two electrode probes 210 are respectively connected to the control part through wires. When the water level in the water collection area 110 reaches the detected water level H1, the two electrode probes 210 are turned on and send signals to the control part, so that the control part sends an alarm information according to the signal.

[0030] There are two detection ports 120 in this embodiment, and the two detection ports 120 correspond one-to-one to the two electrode probes 210 respectively. The correspondence means that the projection of the electrode probe 210 on the side wall of the detection port 120 is located inside the detection port 120, so that the corresponding electrode probe 210 can be observed through the detection port 120. Therefore, it is possible to determine whether the overflow detection structure 200 is installed in place by visually observing the electrode probe 210. In addition, the detection tool in this embodiment is rod-shaped or wire-shaped (such as copper wire), which contains a conductor. The detection tool is respectively extended into the water collection area 110 through the two detection ports 120 so that the two ends of the conductor are in contact with the two electrode probes 210 respectively. The two electrode probes 210 are connected through the conductor. If an alarm signal is issued, it means that the overflow detection structure 200 is in normal working condition. If no alarm signal is issued, it means that the detection tool cannot trigger the overflow detection structure 200, which means that the overflow detection structure 200 is damaged and needs repair.

[0031] Preferably, the aperture of the detection port 120 is between 1 mm and 5.6 mm. When the detection port 120 is a circular hole, the aperture is the diameter of the circular hole. When the detection port 120 is a square hole or a rectangular hole, the aperture is the diameter of the inscribed circle. When the aperture of the detection port 120 is less than 1 mm, it is not conducive to the insertion of the detection tool, which increases the difficulty of detection; and when the detection port 120 is larger than 5.6 mm, the baby's fingers can be inserted into the detection port 120, which is unsafe and the appearance is not beautiful. Therefore, in this embodiment, the aperture of the detection port 120 is preferably 3 mm. Such a design can not only prevent the baby from inserting his fingers into the detection port 120 and causing unsafe situations, and avoid the detection port 120 from being too large to affect the appearance, but also ensure that the detection tool can be inserted into the detection port 120.

[0032] In this embodiment, the side walls of the base 100 include a front side wall 140, and the bottom wall of the base 100 is provided with a water retaining rib 130 extending upward. The water retaining rib 130 and part of the front side wall 140 form a water collection area 110, and the detection port 120 is provided on the part of the front side wall 140 corresponding to the water collection area 110, and the overflow detection structure 200 is arranged close to the front side wall 140. With such a design, when the dishwasher is embedded in the kitchen cabinet, since the front side wall 140 is exposed to the outside, the detection port 120 is provided on the front side wall 140, which is convenient for visual inspection and inspection using detection tools without disassembling the cabinet; in addition, once water overflow occurs in the water collection area 110, the water can also overflow from the detection port 120 on the front side, so that the user can quickly know the overflow situation.

[0033] Preferably, the front side wall 140 of the base in this embodiment is a double-layer structure, including an outer wall 141 and an inner wall 142. Part of the outer wall 141 includes a vertical section 1411 and a guide section 1412. The vertical section 1411 extends from top to bottom, and the guide section 1412 is formed by bending the bottom of the vertical section 1411 inward. The guide section 1412 extends downward and is connected to the inner wall 142. A notch 1413 is formed below the vertical section 1411 and the guide section 1412. The detection port 120 is provided on the inner wall 142, and the guide section 1412 is used to guide the detection tool to pass through the detection port 120. With such a design, the structural strength of the front side wall 140 can be increased by setting the outer wall 141 and the inner wall 142 to ensure the structural integrity of the base 100; in addition, the guide section 1412 can guide the detection tool to be smoothly inserted into the detection port 120, so that the detection tool can be inserted into the area to be detected, thereby improving the detection efficiency; it can also serve as a visual guide to facilitate the observation of the overflow detection structure 200; finally, when the base 100 is injection molded, no additional sliders or inclined tops are required, which is in line with the main demolding direction, simple molding, and low cost.

[0034] To further enhance the effectiveness of guiding the insertion direction of the inspection tool, the inner sidewall 142 of this embodiment includes a bent portion 1421 formed by an outward bend. The bent portion 1421 includes a first bent section 14211 connected to the guide section 1412 and a second bent section 14212 connected to the bottom of the first bent section 14211. The second bent section 14212 extends inward and downward to guide the insertion of the inspection tool. The second bent section 14212 is arranged parallel to the guide section 1412, and the inspection port 120 is provided at the connection between the first bent section 14211 and the second bent section 14212. This design further supports and limits the inspection tool through the second bent section 14212, guiding the inspection tool into the area to be inspected, thereby enhancing the effectiveness of guiding the insertion direction of the inspection tool. In addition, it also conforms to the main demolding direction, is simple to form, and is low in cost.

[0035] The angle α between the guide section 1412 and the horizontal plane is between 20° and 60°. Since the height of the side wall 140 is not high and the detection port 120 is set higher than the detection water level H1, the height range in which the detection port 120 can be set is relatively small. Therefore, when the angle α is less than 20°, the personnel need to lie on the ground for observation, which increases the difficulty of visual inspection; when the angle α is greater than 60°, the line of sight is easily blocked by the body, and the visual guidance effect is weak. It is still difficult for personnel to observe the overflow detection structure 200 when they are crouching. For this reason, the angle α in this embodiment is preferably 30°. Such a design can facilitate personnel to observe the overflow detection structure 200 through the detection port 120 when they are crouching, without having to lie on the ground for observation, thereby improving the feasibility of observation and detection.

[0036] In addition, in this embodiment, the bottom of the inner tank is provided with an electronic device 300 located above the water collection area 110, and the front side wall 140 of the base 100 is provided with a drain outlet (not shown in the figure) connected to the water collection area 110. The drain outlet is set lower than the electronic device 300. In this way, when there is a large amount of water in the water collection area 110 and the water level rises to the height of the drain outlet, the water in the water collection area 110 can be discharged through the drain outlet in time to avoid the electronic device 300 from being damaged by water.

[0037] It should be noted that in this embodiment, the lowest point of the detection port 120 is not lower than the lowest point of the drain outlet. This design prevents water from flowing out of the detection port when the amount of water in the water collection area 110 is small. Preferably, the lowest point of the detection port is flush with the lowest point of the drain outlet. In this case, the drain outlet can be omitted, and the detection port 120 becomes the drain outlet. In the event of overflow, water in the water collection area 110 is discharged from the base 100 through the detection port 120.

[0038] The overflow port in this embodiment is connected to the water collection area 110 through the drainage passage 400. The drainage passage 400 includes an overflow trough 410 and a water guide trough 420. The overflow trough 410 is arranged on the outside of the inner tank. The overflow trough 410 is a long strip trough body with a U-shaped cross-section. The opening of the overflow trough 410 faces upward. Both ends of the overflow trough 410 are connected to the overflow port. The water guide trough 420 is arranged at the bottom of the overflow trough 410. The trough wall or trough bottom of the overflow trough 410 is provided with a water outlet (not shown in the figure). The water outlet is connected to the water guide trough 420. The water guide trough 420 guides water into the water collection area 110. The water outlet can be arranged on the bottom wall of the overflow trough 410 or on the side wall of the overflow trough 410. There is no restriction on this. The overflow port is located on the front side of the inner tank and is lower than the front side of the inner tank, so that the water in the inner tank can flow out from the overflow port first when it is almost full. The specific structure of the drainage path can refer to the existing technology CN217244232 design and will not be described in detail here.

[0039] It is understandable that in other embodiments of the present invention, the inner side wall may not be provided with a bent portion, that is, the inner side wall is a straight wall extending vertically, and the detection port is provided on the straight wall.

[0040] It can be understood that in other embodiments of the present invention, the front side wall of the base is a single-layer structure, and the detection port is provided on the front side wall.

[0041] It can be understood that in other embodiments of the present invention, the number of the detection port is one, the detection port is in the shape of an elongated strip, and one detection port corresponds to two electrode probes at the same time.

[0042] It can be understood that in other embodiments of the present invention, the side walls of the base also include a left side wall, a right side wall and a rear side wall, the detection port can be arranged on the left side wall, the right side wall or the rear side wall, and the water collection area is arranged near the side wall where the detection port is provided.

[0043] It can be understood that in other embodiments of the present invention, the overflow detection structure is a micro switch, which is electrically connected to the control unit. A float is provided in the water collection area, which floats up and down with the water level in the water collection area. When the water level in the water collection area reaches the detection water level, the float triggers the micro switch. When detecting the overflow detection structure, a detection tool is passed through the detection port and triggers the micro switch. If an alarm signal is issued, it means that the micro switch is in normal working condition. If no alarm signal is issued, it means that the micro switch is damaged and needs to be repaired.

[0044] It is understandable that in other embodiments of the present invention, the bottom wall of the base may be recessed downward to form a water collection area.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments.
