Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purifiers, in particular to a combined waterway plate and water purifying and heating integrated machine. BACKGROUND

[0002] The water purifying and heating integrated machine can provide normal temperature water and hot water for users, and is increasingly favored by consumers, gradually becoming an indispensable product in household appliances. The water purifying and heating integrated machine generally includes a filter element and an instant heating body. The working principle is that the filter element filters tap water to produce purified water which is directly output or output after being heated by the instant heating body, so as to realize the functions of outputting normal temperature water or hot water after being connected to a water outlet nozzle.

[0003] Most of the water purifying and heating integrated machines on the market are equipped with a waterway plate. The waterway plate is a connecting component for connecting various waterway components in the water purifying and heating integrated machine and a flow guide component for discharging water, gas and the like out of the machine body. For example, normal temperature water filtered by the filter element and hot water heated by the instant heating body are discharged through the waterway plate. With the technical iteration and update of the water purifying and heating integrated machine, more and more functions are gradually realized, and the use requirements for the waterway plate are also increasing. Mainly, the size of the waterway plate is getting larger and larger, and the internal waterway channel of the waterway plate is getting more and more complex, which leads to the fact that the original one-piece molding method no longer meets the processing requirements of the complex waterway plate. Taking the injection molding of the waterway plate as an example, the traditional simple waterway plate is difficult to demold after being integrally injection molded, and the process is simple. However, the waterway plate with large size and complex waterway channel is not only difficult to injection mold, but even if it can be injection molded, the subsequent demolding is also difficult and the process is complex. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a combined waterway plate to improve the technical problem of complex manufacturing process of the existing complex waterway plate.

[0005] The technical solution adopted by the present application is as follows:

[0006] A combined waterway plate includes a first waterway plate and a second waterway plate. The first waterway plate and the second waterway plate are rotationally connected by a rotating unit. The second waterway plate is provided with a limiting portion. When the first waterway plate and the second waterway plate rotate relative to each other in a first direction, the first waterway plate and the limiting portion are limitedly matched. The limiting portion limits the relative movement of the first waterway plate and the second waterway plate in a second direction, and the second direction is the same as the direction in which the rotation axis of the rotating unit extends. When the first waterway plate and the second waterway plate rotate relative to each other in the opposite direction of the first direction, the first waterway plate and the limiting portion are disengaged.

[0007] In the technical solution, a combined waterway board is provided, which includes two board blocks, i.e., a first waterway board and a second waterway board. The two board blocks are used in combination. The first waterway board can be provided with some waterway channels and airflow channels. The second waterway board can also be provided with some waterway channels and airflow channels. After the first waterway board and the second waterway board are combined, the waterway channels and airflow channels of the two board blocks can be used in combination or independently, so as to realize function superposition.

[0018] The rotating shaft is provided with an outwardly protruding expansion protruding portion, and the rotating shaft is abutted against the inner wall of the rotating hole in an interference fit manner through the expansion protruding portion.

[0019] In the technical solution, the rotating shaft is abutted against the inner wall of the rotating hole in an interference fit manner through the expansion protruding portion, so that the reliability of the cooperation between the rotating shaft and the rotating hole is improved, and the relative shaking of the first waterway plate and the second waterway plate caused by the shaking of the rotating shaft in the rotating hole is avoided.

[0020] The first waterway plate is provided with a wastewater outlet channel and a normal-temperature water outlet channel, and the second waterway plate is provided with an exhaust channel and a hot water outlet channel.

[0052] Reference Figures 1 to 10 As shown in the drawings, the combined waterway plate provided by the present application includes a first waterway plate 1 and a second waterway plate 2. The first waterway plate 1 is rotatably connected to the second waterway plate 2 through a rotating unit. The second waterway plate 2 is provided with a limiting part. When the first waterway plate 1 and the second waterway plate 2 are relatively rotated in a first direction, the first waterway plate 1 is limitedly matched with the limiting part. The limiting part limits the relative movement of the first waterway plate 1 and the second waterway plate 2 in a second direction, which is the same as the direction of the rotation axis of the rotating unit.

Specifically, as shown in the drawings, the first direction is schematically shown by a bidirectional arrow X. Figure 5

[0053] The combined waterway plate provided by the present application includes two plate blocks, i.e., a first waterway plate 1 and a second waterway plate 2. The two plate blocks are used in combination. Some waterway channels and airflow channels can be arranged on the first waterway plate 1, and some waterway channels and airflow channels can also be arranged on the second waterway plate 2. After the first waterway plate 1 and the second waterway plate 2 are combined, the waterway channels and airflow channels of the two plate blocks can be used in communication or independently. Therefore, compared with an integrated waterway plate, the first waterway plate 1 and the second waterway plate 2 share a part of the functions, each has a smaller size and a simpler channel, is convenient to process, and has a simple process. The first waterway plate 1 and the second waterway plate 2 can be manufactured by using a traditional injection molding process. After the two plate blocks are manufactured separately, they are combined and used in combination. In addition, during the assembly of the first waterway plate 1 and the second waterway plate 2, the two plate blocks are rotatably connected through a rotating unit, and then relatively rotated in a first direction to limit the first waterway plate 1 and the limiting part, limit the relative movement in a second direction, prevent the rotating unit from being dislocated and separated along the direction of the rotation axis, and improve the connection reliability. Moreover, the assembly and disassembly of the first waterway plate 1 and the second waterway plate 2 are convenient and fast.

[0054] Regarding the structure of the limiting part and the limiting mode of the limiting part, as a preferred embodiment, as shown in Figure 1 , Figure 2 and Figure 3 ​As shown, the limiting part is provided as a limiting sliding groove 21, and the first waterway plate 1 is provided with a limiting convex rib 11 matched with the limiting sliding groove 21. During assembly, the first waterway plate 1 and the second waterway plate 2 are first connected by rotating units, at this time, the limiting convex rib 11 is located outside the limiting sliding groove 21, then the first waterway plate 1 and the second waterway plate 2 are relatively rotated along the first direction, so that the limiting convex rib 11 slides into the limiting sliding groove 21. In this technical solution, the first waterway plate 1 and the second waterway plate 2 are limited and matched by the limiting sliding groove 21 and the limiting convex rib 11, which is simple in structure, convenient to process, reliable in limiting, and can stably limit the first waterway plate 1 and the second waterway plate 2 after the limiting sliding groove 21 and the limiting convex rib 11 are matched.

[0055] As a preferred embodiment of the present embodiment, as shown in Figures 1 to 3 As shown, the first waterway plate 1 is provided with an abutting part 12, and the second waterway plate 2 is provided with a stop part 22, when the first waterway plate 1 and the second waterway plate 2 are relatively rotated along the first direction, the stop part 22 stops the abutting part 12 to limit the first waterway plate 1 and the second waterway plate 2 from continuing to rotate relatively along the first direction. As shown in Figure 5 As shown, the state when the limiting convex rib 11 and the limiting sliding groove 21 are not matched, at this time, there is still a distance between the stop part 22 and the abutting part 12. As shown in Figure 1 As shown, when the stop part 22 and the abutting part 12 are stopped, it means that the first waterway plate 1 and the second waterway plate 2 have been rotated to the right position along the first direction. By stopping the abutting part 12 by the stop part 22, the rotation angle of the first waterway plate 1 and the second waterway plate 2 along the first direction is limited, so as to avoid excessive rotation of the two. When the stop part 22 stops the abutting part 12, the limiting convex rib 11 is reliably limited in the limiting sliding groove 21, and the assembly personnel can also be informed that the first waterway plate 1 and the second waterway plate 2 have been rotated to the right position, so as to facilitate the next assembly process.

[0056] Further, as shown in Figures 1 to 3 and Figure 5 As shown, the abutting part 12 is provided with a mounting hole 13, the stop part 22 is provided with a screw hole 23, and the combined waterway plate further comprises a screw 8, the screw 8 is arranged in the mounting hole 13 and connected with the screw hole 23. In this technical solution, after the first waterway plate 1 and the second waterway plate 2 are rotated to the right position along the first direction, the stop part 22 stops the abutting part 12, at this time, the mounting hole 13 and the screw hole 23 are just aligned, then the screw 8 is arranged in the mounting hole 13 and connected with the screw hole 23, and then the first waterway plate 1 and the second waterway plate 2 are fixed together by the screw 8, which improves the assembly reliability and prevents the two from being dislocated and shaken.

[0057] As a preferred embodiment of the present embodiment, as shown in Figure 3As shown, the edge of the limiting protruding rib 11 is provided with a protruding rib guide 111, which is provided with a guide slope or a guide arc surface, and the protruding rib guide 111 is used to guide the limiting protruding rib 11 to slide into the limiting sliding groove 21. As another preferred embodiment in the present embodiment, as shown in Figure 2 As shown, the opening of the limiting sliding groove 21 is provided with a sliding groove guide 211, which is provided with a guide slope or a guide arc surface, and the sliding groove guide 211 is used to guide the limiting protruding rib 11 to slide into the limiting sliding groove 21. In the specific implementation, a chamfer can be processed on the edge of the limiting protruding rib 11 and the opening of the limiting sliding groove 21, and the chamfer can be processed into a guide slope, or a round chamfer can be processed into a guide arc surface. The limiting protruding rib 11 and the limiting sliding groove 21 are preferably in interference fit. In the present technical solution, the functions of the protruding rib guide 111 and the sliding groove guide 211 are to guide the limiting protruding rib 11 to slide into the limiting sliding groove 21, to reduce the jamming phenomenon when the first waterway plate 1 and the second waterway plate 2 relatively rotate along the first direction, and to improve the fluency of the combined assembly.

The embodiment is specifically shown, in which the rotating shaft 14 is arranged on the first waterway plate 1 and the rotating hole 24 is arranged on the second waterway plate 2. When assembling, the rotating shaft 14 is inserted into the rotating hole 24 in a predetermined direction to realize the rotating connection of the first waterway plate 1 and the second waterway plate 2, and under the limiting cooperation of the limiting protruding rib 11 and the limiting sliding groove 21, the rotating shaft 14 is prevented from disengaging from the rotating hole 24. In the present technical solution, the first waterway plate 1 and the second waterway plate 2 are rotatably connected through the rotating hole 24 and the rotating shaft 14, which has a simple structure, is easy to process, and is convenient to install.
