[0002] As part of smart homes, dishwashers typically automatically heat the incoming cold water. However, existing heating elements and water pipes are often connected in adjacent contact, making it difficult to heat the water within the pipes during rapid assembly. Therefore, designing a new type of heating element for dishwashers is crucial. For example:

[0003] A heating element for regulating water temperature in a dishwasher, authorized by publication number CN211609687U, offers the following advantages compared to existing technologies: This invention solves the problem of existing dishwashers failing to protect the internal heating element during use, leading to damage during dishwashing. This heating element, with authorization number CN211609687U, provides protection for the heating element, improving the dishwasher's practicality. Furthermore, the use of a slider and a sliding groove reduces friction between the support plate and the fixed plate, extending the support plate's lifespan and preventing... The support plate detaches from the fixed plate. The movable groove limits the position of the first filter. The mounting hole reduces contact between the heating element and the fixed plate. The second filter facilitates water flow inside the fixed plate. The first groove limits the position of the pull block. The combination of the locking block and the locking groove limits the position of the support plate. The anti-slip texture prevents slippage when pulling the fixed block. The vertical plate limits the position of the first filter. The positioning block and the positioning groove prevent the vertical plate from rotating when not needed. The gasket reduces friction between the vertical plate and the dishwasher body.

[0029] Specific examples Figure 1 , Figure 2 and Figure 3As shown, firstly, the heating tube bodies 3 are placed at equal intervals inside the dishwasher body 1. The longitudinal section of the heating tube body 3 is "J" shaped, and the heating tube bodies 3 are connected in a double "J" structure. The distance between two adjacent sets of heating tube bodies 3 is greater than the diameter of the nozzle 23. Then, the two ends of the rear side of the heating tube body 3 are evenly connected with connectors 4. At this time, the connectors 4 are symmetrically arranged about the center line of the heating tube body 3. A cylindrical insulating sleeve 5 is installed on the rear side of the connector 4. The insulating sleeve 5 is connected to the corresponding connector 4 front and back. Then, the insulating sleeve 5 is... The insulating sleeve 5 is locked onto the corresponding groove of the dishwasher body 1. Finally, the conductive plate 6 is installed on the back side of the insulating sleeve 5. The diameter of the conductive plate 6 is larger than that of the insulating sleeve 5. After the conductive plate 6 is connected, the diameters of both the connector 4 and the conductive plate 6 are larger than the diameter of the connecting groove of the insulating sleeve 5 on the dishwasher body 1, making it difficult for the insulating sleeve 5 to slide back and forth. The electrode 7 is connected to the back side of the conductive plate 6 and is welded to the connecting wire 8 through the electrode 7. The entire heating tube is positioned and assembled, which facilitates the positioning and assembly of the heating tube on the dishwasher.

[0030] Specific examples Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, first, place the water supply pipe body 2 horizontally. After keeping the water supply pipe body 2 horizontal, align the nozzles 23, which are evenly spaced on the lower side of the water supply pipe body 2, with the nozzles 23 between two adjacent sets of heating pipe bodies 3. Then, press the water supply pipe body 2 downwards through the gap between the heating pipe body 3 and the dishwasher body 1. The inner wall of the heating pipe body 3, which has a "J"-shaped longitudinal section, contacts the bottom end of the water supply pipe body 2. Next, pull the water supply pipe body 2 forward. The bottom end of the water supply pipe body 2 rubs against the inner wall of the heating pipe body 3, and the heating pipe body 3 and the water supply pipe body 2 slide together until the front side of the water supply pipe body 2 is wrapped by the inner wall of the heating pipe body 3. At this point, the water supply pipe body 2 and the heating pipe body 3 are connected by a snap-fit ​​mechanism. The heating pipe bodies 3 are evenly spaced on the outside of the water supply pipe body 2. The nozzles 23, which are funnel-shaped structures and are equally spaced on the lower side of the water supply pipe body 2, are connected alternately on the left and right. The water supply pipe body 2 is limited on the heating pipe body 3, which facilitates the quick connection between the dishwasher heating pipe and the water supply pipe. Cold water is introduced from the first water inlet pipe 21 and the second water inlet pipe 22. After the cold water passes through the second connecting plate 20 and the connecting pipe 11, it is guided by the first connecting plate 9 to the inside of the water supply pipe body 2. After the connecting wire 8 is connected to the power supply, the connecting wire 8 conducts electricity through the electrode 7, and the heating pipe body 3 is heated. The heating pipe body 3 is set on the outside of the water supply pipe body 2. After the cold water in the water supply pipe body 2 absorbs the heat generated by the heating pipe body 3, it is discharged from the nozzles 23. The heating pipe body 3 and the nozzles 23 are alternately set on the water supply pipe body 2, so that the water sprayed by the nozzles 23 is always in a heated state, which facilitates the heating pipe to intermittently heat the cold water in the sealed pipe.

[0031] Specific examples Figure 1 and Figure 5 As shown, after the water supply pipe body 2 and the heating pipe body 3 are connected, the water supply pipe body 2 is placed in a horizontal position.

After the inner side of the second sealing ring 19 is connected to the outer wall of the connecting block 12, the connecting bolt 15 is screwed on. The connecting bolt 15 connects and reinforces the connecting block 14 and the second connecting plate 20.

[0034] Finally, the first water inlet pipe 21 is engaged on the left side of the dishwasher body 1, extending from the inside of the dishwasher body 1 to the outside. The second water inlet pipe 22 is engaged on the right side of the dishwasher body 1, also extending from the inside of the dishwasher body 1 to the outside. Finally, the U-shaped positioning block 16 is engaged with the protective covers 13 on the left and right sides respectively. The positioning block 16 is pushed so that the rear side of the positioning block 16 contacts the dishwasher body 1. The outer side of the positioning block 16 is provided with positioning plates 17 that are symmetrically distributed vertically.

[0035] The positioning bolt 18 is manually screwed into the positioning plate 17. The positioning bolt 18 has a threaded connection on the outside. When the positioning bolt 18 is screwed, the positioning plate 17 is tightly connected to the dishwasher body 1. The positioning block 16 places the protective cover 13 on the dishwasher body 1. The positioning bolt 18 is symmetrically arranged about the center line of the positioning plate 17, which facilitates the quick connection of the heating tube and the water supply tube. This is the method of using the heating tube of the dishwasher.
