Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of kitchen electronic appliances, and particularly to dishwashers.
Background Art
[0002] Conventional dishwashers include a base and an inner layer. When a failure occurs, water leakage in the inner layer due to abnormal water supply may occur in the dishwasher. Also, when the pipe bursts, problems such as water leakage of water or condensed water may occur. Therefore, in order to prevent water from flowing directly to the floor, it is necessary to collect the leaked or overflowed water, and for this purpose, a water collection area for collecting the above-mentioned water leakage is provided in the base. In order to quickly detect the water leakage problem, an overflow detection structure is provided in the conventional water collection area. When the water level in the water collection area reaches the detection water level, the overflow detection structure is triggered to perform an alarm operation, and prompt the user to perform a detailed inspection of the water leakage problem.
[0003] From this, it can be seen that the accurate installation and normal operation of the overflow detection structure are very important for checking the overflow and water leakage problems. Therefore, conventional dishwashers usually perform a full inspection on the overflow detection structure during the manufacturing process. However, in the conventional dishwasher technology, the overflow protection structure is installed on the rear side of the middle part of the base, so precise inspection cannot be performed without disassembling the machine. Therefore, when performing a function test after the production of the entire machine is completed, only a small number can be extracted for a water injection test, and a full inspection cannot be achieved. Also, when a failure occurs at the user's home, first, it is necessary to check whether a failure has occurred in the overflow detection structure. However, when checking the failure of the overflow detection structure, it also has to be disassembled and confirmed, which is extremely inconvenient, and this reduces the efficiency of the function test for the overflow detection structure.

[0004] [Patent Document 1] Japanese Patent Publication No. 2023-147203 [Overview of the Initiative] [Problems that the invention aims to solve]
[0005] The technical problem that this disclosure aims to solve is to provide a dishwasher that overcomes the shortcomings of the prior art and can perform checks on the overflow detection structure in the finished product state. [Means for solving the problem]
[0006] The dishwasher in this disclosure is a dishwasher including a base and an inner layer, the inner layer having an overflow port, the base having a water collection area for collecting leaked water, an overflow detection structure provided in the water collection area, and the overflow detection structure being triggered when the water level in the water collection area reaches a detection level, wherein an inspection port higher than the detection level is provided on the side wall of the base, the inspection port is installed in correspondence with the overflow detection structure, and the inspection port is used to allow an inspection tool to pass through and check whether the inspection tool can trigger the overflow detection structure, and to visually check through the inspection port whether the overflow detection structure is installed in the predetermined position. [Effects of the Invention]
[0007] According to this disclosure, it is possible to reduce time costs and improve the efficiency of functional checks during production and after-sales maintenance processes. [Brief explanation of the drawing]

[0009] The embodiments will be described in detail below with reference to the drawings. However, unnecessary details may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted.
[0010] The attached drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims.
[0011] The following terms indicating direction or positional relationships, such as "up," "down," "left," "right," "vertical," "horizontal," "inside," "outside," "perpendicular," "horizontal," "peak," and "bottom," are based solely on the direction or positional relationships shown in the drawings and are intended to simplify and streamline the description of this disclosure. They do not explicitly or implicitly suggest that the device / element being referred to necessarily has a specific direction or is configured and operated in a specific direction, and therefore should not be interpreted as limitations on this disclosure.
[0012] (Embodiment 1) Embodiment 1 will be described below with reference to Figures 1 to 5.
[0013] As shown in Figures 1 to 5, the dishwasher of this embodiment includes a base 100 and an inner layer (not shown in the figures). An overflow port is provided in the inner layer. A water collection area 110 for collecting leaked water is provided in the bottom wall of the base 100. 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 unit of the dishwasher, and when the overflow detection structure 200 is triggered, a signal is sent to the control unit, which then issues alarm information based on the signal. An inspection port 120 higher than the detection water level H1 is provided on the side wall of the base 100. This design prevents water from flowing out of the base 100 through the inspection port 120 when the water volume in the water collection area 110 has not yet reached the detection water level H1, and ensures that the overflow detection structure 200 is triggered only after the water level in the water collection area 110 reaches the detection water level H1. The inspection port 120 is installed in conjunction with the overflow detection structure 200 and is used to allow inspection equipment to pass through. In this way, during inspection, the inspection equipment can be extended into the water collection area 110 through the inspection port 120 to check whether the overflow can trigger the overflow detection structure 200, and at the same time, the inspection worker can also observe through the inspection port 120 whether the overflow detection structure 200 is detached and installed in the correct position, thus enabling a 100% inspection of the overflow detection structure 200 without disassembly. In other words, the dishwasher of this embodiment allows for inspection of the overflow detection structure 200 in the finished product state, thus reducing time costs and increasing the efficiency of functional inspections during production and after-sales maintenance.
[0014] Specifically, the overflow detection structure 200 in this embodiment includes two electrode probes 210 mounted at intervals within a water collection area 110. A mounting portion 111 is provided within the water collection area 110. Two mounting holes 1110 extending in the vertical direction are provided on the mounting portion 111. The two electrode probes 210 are assembled and fixed within the two mounting holes 1110. The lower ends of the two electrode probes 210 are installed flush or offset vertically, preferably flush. At this time, the height at which the lower ends of the two electrode probes 210 are located is the detection water level H1. The upper ends of the two electrode probes 210 are each connected to a control unit by lead wires. When the water level in the water collection area 110 reaches the detection water level H1, the two electrode probes 210 become conductive and transmit a signal to the control unit, causing the control unit to issue alarm information based on the signal.
[0015] In this embodiment, there are two inspection ports 120, and each of the two inspection ports 120 corresponds one-to-one with two electrode probes 210. This correspondence means that the projection portion of the electrode probe 210 on the side wall provided in the inspection port 120 is located inside the inspection port 120, allowing the corresponding electrode probe 210 to be observed through the inspection port 120. As a result, by visually observing the electrode probes 210, it is possible to determine whether the overflow detection structure 200 is installed in the predetermined position. Furthermore, the inspection instrument in this embodiment is a rod-shaped or wire-shaped object (for example, a copper wire) containing a conductor, and the inspection instrument extends into the water collection area 110 through each of the two inspection ports 120, bringing both ends of the conductor into contact with the two electrode probes 210, thereby creating electrical conductivity between the two electrode probes 210 via the conductor. If an alarm signal is emitted, it means that the overflow detection structure 200 is operating normally. If no alarm signal is emitted, it means that the inspection device cannot trigger the overflow detection structure 200, which means that the overflow detection structure 200 is damaged and requires maintenance.
[0016] Preferably, the diameter of the inspection opening 120 is between 1 mm and 5.6 mm. If the inspection opening 120 is a circular hole, the diameter is the diameter of the circular hole. If the inspection opening 120 is a square or quadrilateral hole, the diameter is the diameter of the inscribed circle. If the diameter of the inspection opening 120 is less than 1 mm, it becomes difficult to insert inspection tools, increasing the difficulty of the check. If the diameter of the inspection opening 120 exceeds 5.6 mm, a child's finger may get stuck inside the inspection opening 120, creating a dangerous situation, and it also looks unsightly. For this reason, the diameter of the inspection opening 120 in this embodiment is preferably 3 mm. By designing it in this way, it is possible to prevent a child from getting stuck inside the inspection opening 120 and creating a dangerous situation, as well as to prevent the inspection opening 120 from being too large and affecting the appearance, and it is also possible to ensure that inspection tools can be inserted into the inspection opening 120.
[0017] In this embodiment, the side wall of the base 100 includes the front side wall 140. The bottom wall of the base 100 is provided with a water-stopping rib 130 that extends upward. The water-stopping rib 130 and a part of the front side wall 140 surround the water collection area 110. An inspection opening 120 is provided in the part of the front side wall 140 that corresponds to the water collection area 110. The overflow detection structure 200 is provided close to the front side wall 140. With this design, when the dishwasher is installed as a built-in unit in a system kitchen, the front side wall 140 is exposed to the outside, so by providing the inspection opening 120 in the front side wall 140, visual inspection and inspection using inspection tools become easier, and there is no need to disassemble the system kitchen. In addition, even if an overflow occurs in the water collection area 110, the water will overflow from the front inspection opening 120, so the user can easily find out about the overflow situation.
[0018] Preferably, the front wall 140 of the base in this embodiment has a two-layer structure including an outer wall 141 and an inner wall 142. A portion of the outer wall 141 includes a vertical zone 1411 and a guide zone 1412. The vertical zone 1411 is formed by extending from top to bottom. The guide zone 1412 is formed by bending inward from the bottom of the vertical zone 1411. The guide zone 1412 extends inclined downward and connects to the inner wall 142. Notches 1413 are formed below the vertical zone 1411 and the guide zone 1412. An inspection opening 120 is provided on the inner wall 142. The guide zone 1412 is used to guide inspection equipment through the inspection opening 120. In such a design, the structural strength of the front wall 140 can be increased by the installation of the outer wall 141 and the inner wall 142, and the integrity of the base 100 structure can be ensured. Furthermore, by installing the guidance zone 1412, inspection tools can be guided and smoothly inserted into the inspection opening 120, allowing the tools to be inserted into the area requiring inspection, thereby improving inspection efficiency. It also serves as visual guidance, making it convenient for observing the overflow detection structure 200. Finally, when performing injection molding on the base 100, there is no need to use extra sliders or lifters, and it matches the main demolding direction, resulting in simple molding and low costs.
[0019] In order to further enhance the guiding effect on the insertion direction of the inspection instrument, the inner wall 142 of the present embodiment includes a bent portion 1421 formed by bending outward. The bend 1421 includes a first bending zone 14211 connected to the guiding zone 1412 and a second bending zone 14212 connected to the bottom of the first bending zone 14211. The second bending zone 14212 extends inwardly and downwardly inclined to guide the insertion of the inspection instrument. The second bending zone 14212 is installed parallel to the guiding zone 1412. The inspection port 120 is installed at the connection portion between the first bending zone 14211 and the second bending zone 14212. By designing like this, the inspection instrument is supported and its position is limited via the second bending zone 14212, and the inspection instrument is guided and inserted into the area that needs to be inspected, thereby improving the guiding effect on the insertion direction of the inspection instrument. Also, since it conforms to the main demolding direction, the molding is simple and the cost is low.
[0020] The included angle α between the guiding zone 1412 and the horizontal plane is between 20° and 60°. The front wall 140 is not very high, and moreover, the inspection port 120 is installed higher than the detection water level H1, so the range of heights where the inspection port 120 can be installed is relatively small. If the included angle α is less than 20°, the operator has to crawl and observe, increasing the difficulty of visual inspection. If the included angle α is greater than 60°, the line of sight is easily blocked by the main body, the visual guiding effect weakens, and even if the operator bends down, the overflow detection structure 200 cannot be easily observed. Therefore, the included angle α of the present embodiment is preferably 30°. By designing like this, the operator can observe the overflow detection structure 200 from the inspection port 120 just by bending down, without having to crawl on the ground to observe, so the feasibility of observation and checking is enhanced.
[0021] In addition, an electronic device 300 positioned above the water collection area 110 is provided at the bottom of the inner layer of the present embodiment. A drain outlet (not shown in the figure) communicating with the water collection area 110 is provided on the front side wall 140 of the base 100. The drain outlet is installed lower than the electronic device 300. By doing so, even if the amount of water in the water collection area 110 is relatively large and the water level rises to the height of the drain outlet, the water in the water collection area communicates with the water collection area 110 through the drainage passage 400. The drainage passage 400 includes an overflow groove 410 and a water guide groove 420. The overflow groove 410 is provided on the outer side of the inner layer. The overflow groove 410 is an elongated groove body with a U-shaped cross section. The opening of the overflow groove 410 faces upward. Both ends of the overflow groove 410 communicate with the overflow outlet. The water guide groove 420 is provided at the bottom of the overflow groove 410. A water discharge port (not shown in the figure) is provided on the groove wall or the groove bottom of the overflow groove 410. The water discharge port communicates with the water guide groove 420. The water guide groove 420 guides the water flow into the water collection area 110. The water discharge port may be installed on the bottom wall of the overflow groove 410 or on the side wall of the overflow groove 410, and there is no limitation on this. The overflow outlet is provided on the front side of the inner layer and is lower than the front side surface of the inner layer, so when the water in the inner layer approaches full water, it first flows out from the overflow outlet. The specific structure of the drainage passage may refer to the design of the prior art CN217244232, so it will not be described in detail here.
[0022] It should be noted that the lowest point of the inspection port 120 in the present embodiment is higher than the lowest point of the drain outlet. By designing like this, even when the amount of water in the water collection area 110 is not large, it can be prevented from flowing out from the inspection port. Preferably, the lowest point of the inspection port is flush with the lowest point of the discharge port. In this case, the drain outlet is omitted and the inspection port 120 is used as the drain outlet, so that when an overflow occurs, the water in the water collection area 110 can be discharged to the base 100 through the inspection port 120.
[0023] The overflow outlet of the present embodiment communicates with the water collection area 110 through the drainage passage 400. The drainage passage 400 includes an overflow groove 410 and a water guide groove 420. The overflow groove 410 is provided on the outer side of the inner layer. The overflow groove 410 is an elongated groove body with a U-shaped cross section. The opening of the overflow groove 410 faces upward. Both ends of the overflow groove 410 communicate with the overflow outlet. The water guide groove 420 is provided at the bottom of the overflow groove 410. A water discharge port (not shown in the figure) is provided on the groove wall or the groove bottom of the overflow groove 410. The water discharge port communicates with the water guide groove 420. The water guide groove 420 guides the water flow into the water collection area 110. The water discharge port may be installed on the bottom wall of the overflow groove 410 or on the side wall of the overflow groove 410, and there is no limitation on this. The overflow outlet is provided on the front side of the inner layer and is lower than the front side surface of the inner layer, so when the water in the inner layer approaches full water, it first flows out from the overflow outlet. The specific structure of the drainage passage may refer to the design of the prior art CN217244232, so it will not be described in detail here.
[0024] As described above, the dishwasher of this embodiment is a dishwasher including a base 100 and an inner layer, the inner layer is provided with an overflow port, 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, and when the water level in the water collection area 110 reaches the detection level, the overflow detection structure 200 is triggered. An inspection port 120 higher than the detection level is provided on the side wall of the base 100, the inspection port 120 is installed in correspondence with the overflow detection structure 200, and the inspection port 120 is used to allow an inspection tool to pass through and check whether the inspection tool can trigger the overflow detection structure 200, and to visually check whether the overflow detection structure 200 is installed in the predetermined position through the inspection port 120.
[0025] In this embodiment, an inspection port 120 higher than the detection water level is provided on the side wall of the base 100. This design prevents water from flowing out of the base 100 through the inspection port 120 when the water volume in the water collection area 110 has not yet reached the detection water level, and ensures that the overflow detection structure 200 is triggered only after the water level in the water collection area 110 reaches the detection water level. The inspection port 120 is installed in conjunction with the overflow detection structure 200 and is used to allow inspection equipment to pass through. Therefore, during inspection, the inspection equipment can be extended into the water collection area from the inspection port 120 to check whether the overflow detection structure 200 can be triggered. At the same time, inspection workers can also observe through the inspection port 120 whether the overflow detection structure 200 is not detached and is installed in the correct position, enabling a 100% inspection of the overflow detection structure 200 without disassembly. In other words, the dishwasher of this embodiment allows for inspection of the overflow detection structure 200 in the finished product state, thereby reducing time costs and improving the efficiency of functional inspections during production and after-sales maintenance.
[0026] In this embodiment, the side wall of the base 100 includes an outer wall 141 and an inner wall 142. A portion of the outer wall 141 includes a vertical zone 1411 and a guide zone 1412 formed by bending inward from the bottom of the vertical zone 1411. The guide zone 1412 extends downward and is connected to the inner wall 142. The inspection opening 120 is provided on the inner wall 142, and the guide zone 1412 is used to guide inspection tools through the inspection opening 120. In this design, the structural strength of the side wall of the base 100 is increased by installing the outer wall 141 and the inner wall 142, ensuring the integrity of the base 100 structure. Furthermore, by installing the guide zone 1412, inspection tools can be guided and smoothly inserted into the inspection opening 120, allowing the inspection tools to be inserted into the area requiring inspection, thereby improving inspection efficiency. It also serves as a visual guide, making it convenient for observing the overflow detection structure 200. Finally, when performing injection molding on base 100, there is no need to use extra sliders or lifters, and it matches the main demolding direction, making molding easy and cost-effective.
[0027] In this embodiment, the inner wall 142 includes a bent portion 1421 formed by bending outward. The bent portion 1421 includes a first bent zone 14211 connected to the guide zone 1412 and a second bent zone 14212 connected to the bottom of the first bent zone 14211. The second bent zone 14212 extends inward and downward, guiding the insertion of the inspection tool. The inspection opening 120 is installed at the connection point between the first bent zone 14211 and the second bent zone 14212. This design further supports and limits the position of the inspection tool via the second bent zone 14212, guiding the tool into the area that needs to be inspected and inserting it, thereby improving the guiding effect on the insertion direction of the inspection tool. Furthermore, since it matches the main demolding direction, molding is simple and the cost is low.
[0028] In this embodiment, the angle between the guidance zone 1412 and the horizontal plane is 20° to 60°. This design allows workers to observe the overflow detection structure 200 through the inspection opening 120 simply by bending down and crouching, eliminating the need to crawl on the ground, thus improving the feasibility of observation and checking.
[0029] In this embodiment, electronic equipment 300 is provided at the bottom of the inner layer, above the water collection area 110. A drain port communicating with the water collection area 110 is provided on the side wall of the base 100, and the drain port is installed lower than the electronic equipment 300. By designing it this way, if the amount of water in the water collection area 110 is relatively large, the water in the water collection area 110 can be quickly drained through the drain port, preventing the electronic equipment 300 from coming into contact with the water and being damaged.
[0030] In this embodiment, the lowest point of the inspection port 120 is higher than the lowest point of the drain port. This design prevents water from flowing out of the inspection port 120 when the amount of water in the water collection area 110 is not large.
[0031] In this embodiment, the side wall of the base 100 includes the front side wall 140, the inspection opening 120 is provided on the front side wall 140, and the overflow detection structure 200 is installed close to the front side wall 140. With this design, when the dishwasher is installed as a built-in type in a system kitchen, the front side wall 140 is exposed to the outside, so by providing the inspection opening 120 on the front side wall 140, visual inspection and inspection using inspection tools become easier, and there is no need to disassemble the system kitchen. In addition, if an overflow occurs, water will spill out from the front inspection opening 120, so the user can easily find out about the overflow situation.
[0032] In this embodiment, the overflow detection structure 200 includes two electrode probes 210 installed at intervals within the water collection area 110, and when the water level in the water collection area 110 reaches the detection level, the two electrode probes 210 become electrically connected. The inspection port 120 is installed to correspond to both electrode probes 210 simultaneously, or there are two inspection ports 120, each installed to correspond to two electrode probes 210.
[0033] In this embodiment, there are two inspection ports 120, each corresponding to one of the two electrode probes 210, and the diameter of the inspection ports 120 is between 1 mm and 5.6 mm. This design not only prevents infants from inserting their fingers into the inspection ports 120 and creating dangerous situations, but also prevents the inspection ports 120 from being too large and affecting the appearance, and ensures that inspection equipment can be inserted into the inspection ports 120.
[0034] In this embodiment, the overflow detection structure 200 is a microswitch, and a float is provided in the water collection area 110 that floats up and down in accordance with the water level in the water collection area 110. When the water level in the water collection area 110 reaches the detection level, the float triggers the microswitch.
[0035] (Other embodiments) As described above, Embodiment 1 has been explained as an example of the technology disclosed in this application. However, the technology in this disclosure is not limited to this and can be applied to embodiments that have been modified, replaced, added, or omitted. Furthermore, it is possible to create new embodiments by combining the components described in Embodiment 1 above.
[0036] Therefore, other embodiments are illustrated below.
[0037] In other embodiments, no bent portion is provided in the inner wall; that is, the inner wall is a vertically extending straight wall, and the inspection opening may be provided on the straight wall.
[0038] In other embodiments, the front wall of the base is a single-layer structure, and an inspection opening may be provided in the front wall.
[0039] In other embodiments, there may be one inspection port, which may be elongated in shape, and one inspection port may be installed to accommodate two electrode probes simultaneously.
[0040] In other embodiments, the side walls of the base further include a left side wall, a right side wall, and a rear side wall, and inspection openings may be provided on the left side wall, the right side wall, or the rear side wall, and the water collection area may be provided adjacent to the side wall on which the inspection openings are located.
[0041] In other embodiments, the overflow detection structure is a microswitch, which is electrically connected to a control unit. A float is provided in the water collection area that moves up and down according to the water level in the water collection area. When the water level in the water collection area reaches the detection level, the float can trigger the microswitch. To inspect the overflow detection structure, an inspection tool is passed through the inspection port to trigger the microswitch. If an alarm signal is emitted, it means that the microswitch is functioning normally. If no alarm signal is emitted, it means that the microswitch is damaged and needs repair.
[0042] In other embodiments, the bottom wall of the base may further form a water collection area by collapsing downward.
