[0048] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0049] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Dishwashers are generally equipped with heating elements inside, which can quickly convert electrical energy into heat energy, causing the water temperature to rise rapidly, thereby shortening the washing time and improving washing efficiency.

[0050] Heating elements are typically connected to an external power source via terminals. In related technologies, the terminals are usually fitted with plastic insulating sleeves to prevent electric shock. When the heating element is working continuously, the temperature of the terminals will rise. Under high temperatures, the insulating sleeves may melt and drip onto non-flame-retardant components, which could easily cause a fire and pose a certain safety hazard.

[0051] To resolve the above issues, please refer to [link / reference]. Figures 1 to 4 This application provides a dishwasher, including an inner tank 100, a heating element 200, a base 300, and a flame-retardant component 400.

[0052] The inner tank 100 may have a square structure, and the internal space of the inner tank 100 may form a washing chamber 100a. The inner tank 100 may be made of metal, thereby giving it better strength; of course, the inner tank 100 may also be made of plastic, and this application does not limit this. Specifically, the inner tank 100 may include a top plate 110, two side shells 120, a back plate 130, and a bottom plate 140. The top plate 110 and the bottom plate 140 are arranged opposite each other in the height direction of the body. The two side shells 120 and the back plate 130 are connected between the top plate 110 and the bottom plate 140. The two side shells 120 are arranged opposite each other in the width direction of the body. The back plate 130 is connected between the two side shells 120, so that a washing chamber 100a with an opening can be formed between the top plate 110, the two side shells 120, the back plate 130, and the bottom plate 140.

[0053] The heating element 200 includes a heating element body 210 and a terminal block 220 connected to the heating element body 210. The heating element 200 is located inside the washing chamber 100a and is responsible for converting electrical energy into heat energy to heat the washing water and improve the washing efficiency. The terminal block 220 is connected to the heating element body 210 and is located outside the washing chamber 100a for easy connection to an external power source. In order to prevent electric shock from touching, the surface of the terminal block 220 is generally covered with an insulating sleeve made of plastic.

[0054] The base 300 is located at the bottom of the inner tank 100. It is connected to the inner tank 100 and provides structural support for the inner tank 100 and the entire dishwasher. The base 300 can be made of plastic. The base 300 can also serve as a collection area for washing water, which is then drained through the drainage system.

[0055] The flame-retardant component 400 is located below the terminal block 220. The flame-retardant component 400 can be connected to the inner liner 100, the base 300, or both simultaneously. There are no restrictions on this connection. Because the flame-retardant component 400 is located below the terminal block 220, the temperature of the terminal block 220 will rise when the heating element 200 is working continuously. Under high temperature conditions, the plastic insulating sleeve may melt. The melted insulating sleeve will drip onto the surface of the flame-retardant component 400 below under gravity, reducing the possibility of it falling onto other parts of the base 300. The flame-retardant component 400 can maintain its structural integrity under high temperature conditions, preventing fire.

[0056] Please see Figure 5 as well as Figure 6In one embodiment of this application, the surface of the flame retardant 400 is provided with reinforcing ribs 410. The reinforcing ribs 410 can increase the mechanical strength of the flame retardant 400, making it more resistant to external pressure and impact. During the operation of the dishwasher, even if it encounters vibration or external force, the flame retardant 400 can remain stable and is not easily deformed or damaged.

[0057] The flame-retardant component 400 can be made of metal, such as stainless steel, aluminum alloy, or copper. It can also be made of ceramic, which has extremely high heat resistance and flame retardancy and can withstand high temperatures without deformation or combustion. There are no restrictions on the material of the flame-retardant component 400. When the flame-retardant component 400 is made of metal, the reinforcing rib 410 can be integrally formed with the flame-retardant component 400. In this way, the flame-retardant component 400 and the reinforcing rib 410 can have excellent structural integrity and structural strength.

[0058] The reinforcing rib 410 can be provided on the upper surface of the flame-retardant component 400, or on the lower surface of the flame-retardant component 400, or both the upper and lower surfaces of the flame-retardant component 400 can be provided with reinforcing rib 410. All of the above methods can improve the structural strength of the flame-retardant component 400.

[0059] Please refer to some embodiments of this application. Figure 6 At least some of the reinforcing ribs 410 are provided on the upper surface of the flame-retardant component 400. That is, the reinforcing ribs 410 can be provided only on the upper surface of the flame-retardant component 400, or they can be provided on both the upper and lower surfaces of the flame-retardant component 400. The reinforcing ribs 410 provided on the upper surface of the flame-retardant component 400 and the flame-retardant component 400 form a receiving groove 41a. In this way, the melted insulating sleeve can fall into the receiving groove 41a and is not easy to roll from the receiving groove 41a to other non-flame-retardant components. Thus, while improving the structural strength of the flame-retardant component 400, the safety of the entire dishwasher is further improved.

[0060] Please see Figure 6 In some embodiments, the flame retardant 400 includes a plate portion 420 and a wire portion 430. The plate portion 420 is located below the terminal block 220 and is used to receive dripping melted insulating sleeve. The plate portion 420 can be installed on the inner liner 100, or on the base 300, or on both the inner liner 100 and the base 300.

[0061] The wire-passing part 430 is provided on the side wall of the plate part 420. The wire-passing part 430 has a wire-passing groove 430a for the wire to pass through. The wire is electrically connected to the terminal 220. The wire-passing groove 430a can constrain the wire. On the one hand, the design of the wire-passing part 430 allows the wire to pass through the wire-passing groove 430a and be electrically connected to the terminal 220. On the other hand, the wire-passing groove 430a can restrict the movement of the wire and reduce the damage to the insulation layer caused by the loosening or friction of the wire.

[0062] On the other hand, since the wire threading part 430 is located on the side wall of the plate body part 420, the melted insulation sleeve falls onto the upper surface of the plate body part 420. By restricting the movement of the wire through the wire threading groove 430a, the melted insulation sleeve can also be prevented from dripping onto the surface of the wire outside the side wall of the plate body part 420, thereby further improving the safety of the entire dishwasher.

[0063] Furthermore, based on the setting of the wire guide 430a, when constraining the wire, the user can directly insert the wire through the slot of the wire guide 430a into the wire guide 430a, that is, the plug of the wire does not need to pass through the wire guide 430a, which facilitates the miniaturization and lightweight design of the entire wire guide 430.

[0064] The threading portion 430 can be a separate structure from the plate portion 420 and connected together, or it can be an integral structure formed by the threading portion 430 and the plate portion 420. No further limitations are imposed in this embodiment. The threading groove 430a can be formed jointly by the plate portion 420 and the threading portion 430, or it can be formed solely by the threading portion 430. This embodiment is described exemplarily using the plate portion 420 and the threading portion 430 forming the threading groove 430a.

[0065] Please see Figure 6 as well as Figure 7 In some embodiments, along the depth direction of the wire-passing groove 430a, the wire-passing groove 430a sequentially includes an inlet section, a transition section and a wire-passing section, and the cross-sectional area of ​​the wire-passing groove 430a gradually decreases from the inlet section to the transition section, and gradually increases from the transition section to the wire-passing section.

[0066] The wire enters the wire guide 430a through the slot opening, passing through the entrance section, transition section, and guide section in sequence. Compared to the transition section, the larger cross-sectional area of ​​the entrance section facilitates the initial introduction of the wire, reduces friction and resistance during wire pulling, and makes the pulling process smoother. Compared to the transition section, the larger cross-sectional area of ​​the guide section can fully accommodate the wire and makes it difficult for it to slip out of the transition section, thus restraining the movement of the wire.

[0067] It should be noted that the connection points of the entry section, transition section, and through section are smooth transitions. These smooth transitions allow the wire to pass through more smoothly during the threading process, reducing difficulties caused by increased resistance. Furthermore, in the event of wire damage, it facilitates the removal of the wire from the threading groove 430a for easy repair and replacement. In addition, the smooth transition design prevents the wire from being worn down due to sudden changes in direction or being cut by sharp edges when passing through threading grooves 430a with different cross-sectional areas.

[0068] In another embodiment of this application, the threading portion 430 is elastic and includes a connecting end and a free end. The connecting end is connected to the plate portion 420, and the free end elastically abuts against the side wall of the plate portion 420.

[0069] Thus, by having the user move the free end of the wire threading part 430, the free end can be separated from the plate part 420, thereby allowing the wire to be placed into the wire threading groove 430a. Under the elastic reset of the wire threading part 430, the free end abuts against the side wall of the plate part 420, which can effectively reduce the possibility of the wire coming off the wire threading groove 430a.

[0070] When the flame-retardant part 400 is a metal part, the plate part 420 can be integrally formed with the threading part 430, that is, the threading part 430 is also a metal part. Therefore, the threading part 430 has elasticity. In this way, the flame-retardant part 400 can be guaranteed to have structural strength, and there is no need to use other elastic materials to make the threading part 430, which reduces the manufacturing difficulty.

[0071] It is understood that the heating tube body 210 can be disposed on the side wall of the washing chamber 100a or on the bottom wall of the washing chamber 100a. In this embodiment, the heating tube body 210 is exemplarily described as being disposed on the bottom wall of the washing chamber 100a.

[0072] Please return and refer to Figure 2 In this embodiment, the heating tube body 210 is disposed on the bottom wall of the washing chamber 100a, and the wiring terminal 220 passes through the bottom wall and is located below the bottom wall. Placing the heating tube 200 at the bottom ensures that the water is heated rapidly when injected. Since the water enters the washing chamber 100a from the bottom, placing the heating tube 200 at the bottom can maximize the heating efficiency, so that the water reaches the ideal washing temperature when flowing through the washing chamber 100a.

[0073] When the heating element body 210 is located on the bottom wall of the washing chamber 100a, in order to save materials, the wiring terminal 220 is inserted through the bottom wall and located below the bottom wall. The flame retardant component 400 is also located below the bottom wall. In related technologies, the water pump, motor and other structures of the dishwasher are located between the base 300 and the inner tub 100. Thus, the flame retardant component 400 and the wiring terminal 220 are also located below the bottom wall to effectively utilize the space between the inner tub 100 and the base 300. Since it only occupies vertical space, it avoids occupying horizontal space. This layout makes the entire dishwasher more compact in structural design, which is conducive to reducing the overall size of the equipment and improving space utilization.

[0074] Please see Figures 8 to 10To ensure the stability of the flame-retardant component 400 during dishwasher operation, in this embodiment, the flame-retardant component 400 has a first connecting portion 440, and the base 300 has a second connecting portion 310. The first connecting portion 440 and the second connecting portion 310 are connected. Through the direct connection between the first connecting portion 440 and the second connecting portion 310, a stable overall structure is formed between the flame-retardant component 400 and the base 300, which helps to improve the overall stability and durability of the flame-retardant component 400, making the entire flame-retardant component 400 less prone to loosening or damage when subjected to external forces or vibrations.

[0075] Specifically, the first connecting part 440 may be a flame-retardant component 400 with a first connecting seat and a first connecting hole. The second connecting part 310 may be a base 300 with a second connecting seat and a second connecting hole. When the first connecting part 440 and the second connecting part 310 are connected, the first connecting seat and the second connecting seat can fit together, and the first connecting hole and the second connecting hole can be opposite each other. The flame-retardant component 400 can be fixed relative to the base 300 by fasteners passing through the first connecting hole and the second connecting hole. The fasteners can be screws, bolts, or other fasteners in the prior art, and no restrictions are placed here.

[0076] Understandably, the flame-retardant component 400 can also be connected to the inner liner 100 in the same way.

[0077] In this embodiment of the application, the base 300 includes a base body 320 and a side plate 330. The side plate 330 is disposed above the base body 320 and is used to connect with the inner liner 100 to support the inner liner 100.

[0078] In this way, the inner liner 100 and the base body 320 have sufficient clearance to accommodate the placement of the wiring terminal 220, flame-retardant components 400, and structures such as water pumps and motors, and also facilitate future maintenance and repair.

[0079] The dishwasher in this embodiment also includes a door 150, which is rotatably connected to the inner tub 100 to open and close the washing chamber 100a. The door 150 is located on the front side of the inner tub 100, and the side plate 330 is located on the rear side of the inner tub 100. The dishwasher also includes a connecting assembly that is connected to the base 300 and the inner tub 100 so that the base 300 provides support for the front side of the inner tub 100.

[0080] Thus, the side plate 330 supports the rear side of the inner liner 100, and the connecting component can support the front side of the inner liner 100, which is equivalent to reducing the contact points between the inner liner 100 and the base 300. This reduces the probability of the base 300 contacting the inner liner 100 during transportation and handling, thereby causing the inner liner 100 to deform.

[0081] Based on the previous embodiment, in order to improve the strength of the side plate 330, a reinforcing plate is provided on the front side of the side plate 330. The reinforcing plate can be integrally formed with the side plate 330, thereby further improving the strength of the entire base 300 and ensuring stability when supporting the inner liner 100.

[0082] The side panel 330 has an upward-facing support surface 330a, which faces the inner liner 100, and at least a portion of the flame-retardant component 400 is supported on the support surface 330a. With the support of the support surface 330a, the flame-retardant component 400 can be prevented from being suspended during installation, thereby improving the stability of the flame-retardant component 400 structure.

[0083] Please see Figure 5 as well as Figure 6 In one embodiment of this application, the inner side of the side plate 330 has a first upright plate structure 340. The first upright plate structure 340 can be integrally formed with the side plate 330. The first upright plate structure 340 strengthens the side plate 330 to improve the stability of the side plate 330 and the first upright plate structure 340. One of the first upright plate structure 340 and the flame retardant member 400 forms a limiting groove, and the other forms a protrusion that cooperates with the limiting groove.

[0084] In this configuration, the first vertical plate structure 340 may have a protrusion, and the flame-retardant component 400 may have a limiting groove; alternatively, the first vertical plate structure 340 may have a protrusion, and the flame-retardant component 400 may have a limiting groove; or the first vertical plate structure 340 may have both a protrusion and a limiting groove, and correspondingly, the flame-retardant component 400 may also have a matching limiting groove and a protrusion. The number of protrusions is not limited and can be set according to actual conditions.

[0085] In this embodiment, the protrusion and the limiting groove cooperate to restrict the movement of the flame retardant 400 in the left and right directions, thereby improving the stability of the flame retardant 400 relative to the base 300 and the inner liner 100. In addition, it can also play a role in pre-positioning, so that when the flame retardant 400 is installed, it can be ensured that the flame retardant 400 is located below the terminal 220.

[0086] Please see Figure 10 In another embodiment of this application, the inner surface of the base body 320 has a second upright plate structure 350, one of the second upright plate structure 350 and the flame retardant member 400 forms a guide groove, and the other forms a guide portion, which cooperates with the guide groove.

[0087] The flame retardant component 400 can be installed in place by the cooperation of the guide part and the guide groove, ensuring that the flame retardant component 400 is located below the terminal 220. The shape of the guide part and the guide groove is not limited. For example, the guide part can be a strip shape, a prism shape, etc.

[0088] It is understandable that the second vertical plate structure 350 may have a guide portion and the flame-retardant component 400 may have a guide groove; alternatively, the second vertical plate structure 350 may have a guide portion and the flame-retardant component 400 may have a guide groove; or the second vertical plate structure 350 may have both a guide portion and a guide groove, and correspondingly, the flame-retardant component 400 may also have a matching guide groove and guide portion. The number of guide portions is not limited and can be set according to actual conditions.

[0089] Different kitchens may have different floor heights, layouts, and spatial designs. A dishwasher with a 300mm height-adjustable base can be adjusted to suit the specific needs of your kitchen, ensuring stable placement and maximizing space utilization.

[0090] Therefore, in the embodiments of this application, please refer back to the previous section. Figure 7 The dishwasher also includes a lifting assembly 500, which includes a lifting component 510, a driving component 520, and a protective cover 530. The lifting component 510 is movably mounted on the base 300. The driving component 520 is driven to connect with the lifting component 510 and is used to drive the lifting component 510 to lift. The protective cover 530 is fitted onto the lifting component 510.

[0091] The drive component 520 includes a drive motor, a main gear, a bushing, and a secondary gear. The drive motor is mounted on the base 300 and is driven by the main gear. The main gear and the secondary gear are meshed together. The bushing is rotatably mounted on the base 300 via a bearing, and the secondary gear is provided on its outer surface.

[0092] The lifting component 510 includes a support base and a screw that are fixed to each other. The support base is located below the base 300, and the screw passes through the base 300 and is threadedly connected to the bushing. When the drive motor drives the main gear to rotate, the bushing also rotates relative to it, thereby driving the screw to rise and fall. When the screw rises and falls, it can drive the support base to rise and fall, thereby causing the base 300 to rise and fall relative to the support base, and thus adjusting the height of the base 300.

[0093] The protective sleeve 530 is fitted onto the screw to prevent impurities or parts from entering the screw threads. Furthermore, the flame retardant component 400 has a clearance area 400a for avoiding the protective sleeve 530, thereby making the lifting assembly 500 and the flame retardant component 400 fit together compactly, which facilitates the lightweight and miniaturized design of the entire dishwasher.

[0094] It is understandable that the lifting component 500 can be set to one or multiple, depending on the actual situation, and no further restrictions will be imposed here.
