[0043] like Figures 1 to 8 As shown, this embodiment provides an auxiliary spray pipeline structure, which can simplify the assembly process and reduce the processing cost and subsequent maintenance cost. The auxiliary spray pipeline structure includes a first fixing seat 1 and an auxiliary spray pipe 3.

[0044] Among them, see Figure 1 and Figure 2 The first fixing base 1 is arranged on the water collecting tank 100 of the dishwasher, and the first fixing base 1 is provided with a first installation channel 111 (such as Figure 4 As shown in FIG. 1 , the first installation channel 111 is connected to the water outlet of the water collection tank 100. The first end of the auxiliary spray pipe 3 is detachably connected to the first installation channel 111, and the second end of the auxiliary spray pipe 3 is configured to connect to the auxiliary spray head 200 of the dishwasher.

[0045] The auxiliary spray pipe structure provided in this embodiment is provided with a first installation channel 111 on the first fixing seat 1, so that when assembling the spray pipe structure, it is only necessary to insert the first end of the auxiliary spray pipe 3 into the first installation channel 111, so that the auxiliary spray pipe 3 can be connected with the water diversion valve 400 of the dishwasher through the water diversion port on the water collection tank 100, and the water diversion valve 400 distributes the washing water to the auxiliary spray pipe 3, and then partially rinses the tableware to be washed through the auxiliary nozzle 200. Since the auxiliary spray pipe 3 is detachably connected to the first fixing seat 1, the auxiliary spray pipe 3 can be processed and manufactured separately, which reduces the processing difficulty of the auxiliary spray pipe 3, and makes the later assembly and disassembly simpler, and the maintenance cost is low.

[0046] In this embodiment, three water outlets are provided on the water collection tank 100, and two water outlet channels connected to the bottom spray arm and the inner water pipe are provided on the first fixing seat 1. The three water outlets are connected to the first installation channel 111 and the two water outlet channels in a one-to-one correspondence. After the washing pump of the dishwasher is started, the water collected in the water collection tank 100 can be passed into the valve cavity of the water diversion valve 400, and then distributed to each spray arm and the auxiliary nozzle 200 through the water diversion valve 400 through the water diversion ports to achieve cyclic flushing.

[0047] Optionally, see Figure 1 , Figure 3 , Figure 4 and Figure 5The auxiliary spray pipe structure also includes a first fastener 4, and the first end of the auxiliary spray pipe 3 is detachably fixed to the first installation channel 111 through the first fastener 4. The first fastener 4 is provided so that the first end of the auxiliary spray pipe 3 can be firmly fixed to the first fixing seat 1, thereby ensuring the installation stability of the auxiliary spray pipe 3. The first end and the second end mentioned above refer to the two ends of the auxiliary spray pipe 3, respectively.

The fixing boss 11 provides an installation foundation for fixing the auxiliary spray pipe 3, which can ensure the stable installation of the auxiliary spray pipe 3. The auxiliary spray pipe 3 is limited to the first mounting channel 111 by the pressing method of the first fastener 4, and is firmly fixed, and there is no need to open a hole in the auxiliary spray pipe 3, which reduces the processing difficulty of the auxiliary spray pipe 3.

[0049] Exemplarily, the first fastener 4 is a screw, and the first connecting hole is a threaded hole. The screw is screwed into the threaded hole until the end of the screw presses against the auxiliary spray pipe 3, and the disassembly and assembly operations are simple.

[0050] Furthermore, a seal (such as a rubber seal) may be provided on the threaded hole and / or the screw to seal the screw with the threaded hole to prevent water in the first installation channel 111 from overflowing through the threaded hole, thereby ensuring that the pressure at the auxiliary nozzle 200 is sufficient.

[0051] Optionally, see Figure 4 , the tightening direction of the first fastener 4 is perpendicular to the extending direction of the auxiliary spray pipe 3. That is, the force direction of the first fastener 4 is perpendicular to the length direction of the auxiliary spray pipe 3. Such a setting can firmly tighten the auxiliary spray pipe 3 in the first installation channel 111, thereby improving the fixing reliability of the auxiliary spray pipe 3.

[0052] Optionally, see Figure 1 and Figure 8 The auxiliary spray pipe structure also includes a second fixing seat 2, which is arranged on the inner tank 300 of the dishwasher, and a second installation channel 21 (such as Figure 5As shown in the figure, the second end of the auxiliary spray pipe 3 is detachably connected to the second installation channel 21, and the water outlet end of the second installation channel 21 is used to connect the auxiliary spray head 200 of the dishwasher. By providing the second fixing seat 2 and arranging the second installation channel 21 on the second fixing seat 2, the auxiliary spray pipe 3 and the auxiliary spray head 200 are also detachably installed, and the auxiliary spray pipe 3 can be processed and manufactured separately. In the later stage, it is only necessary to respectively insert the two ends of the auxiliary spray pipe 3 into the first fixing seat 1 and the second fixing seat 2, which further reduces the processing difficulty of the auxiliary spray pipe 3 and lowers the maintenance cost.

[0053] Optionally, see Figure 1 , Figure 5 and Figure 7 The second end of the auxiliary spray pipe 3 is detachably fixed to the second installation channel 21 by the second fastener 5. The second fastener 5 enables the second end of the auxiliary spray pipe 3 to be firmly fixed to the second fixing seat 2, thereby ensuring the installation stability of the auxiliary spray pipe 3 and the second fixing seat 2.

[0054] Optionally, see Figure 3 , Figure 5 and Figure 7 The second fixing seat 2 is provided with a second connecting column 22, and a second connecting hole 221 communicating with the second installation channel 21 is opened on the second connecting column 22. The second fastener 5 is passed through and connected to the second connecting hole 221, and is pressed against the auxiliary spray pipe 3. The auxiliary spray pipe 3 is limited to the second installation channel 111 by the pressing method of the second fastener 5, and is firmly fixed. There is no need to open a hole on the auxiliary spray pipe 3, which simplifies the processing procedure of the auxiliary spray pipe 3 and reduces the processing cost.

[0055] Exemplarily, the second fastener 5 is a screw, and the second connection hole 221 is a threaded hole. The screw is screwed into the threaded hole until the end of the screw presses against the auxiliary spray pipe 3, and the disassembly and assembly operations are simple.

[0056] Furthermore, a seal (such as a rubber seal) may be provided on the threaded hole and / or the screw to seal the screw with the threaded hole to prevent water in the second installation channel 21 from overflowing through the threaded hole, thereby ensuring that the pressure at the auxiliary nozzle 200 is sufficient.

[0057] Optionally, see Figure 5 , the tightening direction of the second fastener 5 is perpendicular to the extending direction of the auxiliary spray pipe 3. That is, the force direction of the second fastener 5 is perpendicular to the length direction of the auxiliary spray pipe 3. Such an arrangement can firmly tighten the auxiliary spray pipe 3 in the second installation channel 21, thereby improving the fixing reliability of the auxiliary spray pipe 3.

[0058] Optionally, the auxiliary spray pipe 3 is made of metal material, and when installing the auxiliary spray pipe 3, the first fastener 4 (second fastener 5) presses the auxiliary spray pipe 3 to cause a certain deformation, thereby ensuring the fastening effect. Exemplarily, the metal material is stainless steel.

[0059] Optionally, see Figure 1 , Figure 2 and Figure 7 The second fixing seat 2 is also provided with a water outlet 23 connected with the second installation channel 21, and the nozzle 201 of the auxiliary nozzle 200 is connected with the water outlet 23. The water flow distributed by the water diversion valve 400 reaches the nozzle 201 through the first installation channel 111, the auxiliary spray pipe 3, the second installation channel 21 and the water outlet 23, and then the washing water is sprayed to the tableware to be washed through the nozzle 201.

[0060] Furthermore, a variety of types of nozzles 201 can be provided on the nozzle 200, such as a direct spray nozzle and a shower nozzle. The nozzle 200 is rotatably mounted on the second fixed seat 2. By rotating the nozzle 200, one of the nozzles 201 can be connected to the water outlet 23 to adjust different water outlet modes.

[0061] Optionally, see Figure 4 A first stop surface 113 is provided in the first installation channel 111, and the end of the first end of the auxiliary spray pipe 3 stops at the first stop surface 113. The provision of the first stop surface 113 can locate the insertion depth of the auxiliary spray pipe 3 in the first installation channel 111, so that the auxiliary spray pipe 3 can be accurately inserted into place. At the same time, the first stop surface 113 can limit the axial direction of the auxiliary spray pipe 3, prevent the auxiliary spray pipe 3 from axially moving, and further improve the installation stability of the auxiliary spray pipe 3.

[0062] Furthermore, a second stop surface (not shown) may be provided in the second installation channel 21, and the second end of the auxiliary spray pipe 3 stops at the second stop surface. In this way, the second stop surface positions the insertion depth of the auxiliary spray pipe 3 in the second installation channel 21, and at the same time limits the axial position of the auxiliary spray pipe 3, thereby improving the installation stability of the auxiliary spray pipe 3.

[0063] Optionally, see Figure 1 and Figure 6 A support frame 12 is provided on the first fixing seat 1. The support frame 12 is located on the extension path of the auxiliary spray pipe 3 and supported below the auxiliary spray pipe 3. The support frame 12 can support and limit the auxiliary spray pipe 3, prevent the auxiliary spray pipe 3 from shaking, and ensure that the auxiliary spray pipe 3 is firmly fixed in the inner tank 300.

The setting of the limit slot 1221 can prevent the auxiliary spray pipe 3 from moving left and right relative to the support portion 122, so that the support portion 122 stably supports and fixes the auxiliary spray pipe 3.

[0065] Furthermore, the auxiliary spray pipe 3 is a circular tube, and the limiting slot 1221 is an arc-shaped slot, which can increase the contact area between the auxiliary spray pipe 3 and the limiting slot 1221 and improve the supporting stability of the cantilever 121 and the support part 122 for the auxiliary spray pipe 3.

[0066] Further, see Figure 6 A reinforcing rib 123 is provided at the connection between the support portion 122 and the cantilever 121. The reinforcing rib 123 can increase the connection strength between the support portion 122 and the cantilever 121, prevent the support portion 122 from bending and deforming, and thus stably support the auxiliary spray pipe 3.

[0067] The present embodiment also provides a dishwasher, comprising a housing, an inner tank 300, and the auxiliary spray pipeline structure as described above, wherein the inner tank 300 is disposed in the housing, and the auxiliary spray pipeline structure is disposed in the inner tank 300. When the dishwasher adopts the auxiliary spray pipeline structure, when assembling the spray pipeline structure, it is only necessary to insert the first end of the auxiliary spray pipe 3 into the first installation channel 111, and insert the second end of the auxiliary spray pipe 3 into the second installation channel 21, so that the auxiliary spray pipe 3 can be connected to the water diversion valve 400 of the dishwasher through the water diversion port on the water collection tank 100, and the water diversion valve 400 distributes the washing water to the auxiliary spray pipe 3, and then partially rinses the tableware to be washed through the auxiliary nozzle 200. Since the auxiliary spray pipe 3 is detachably connected to the first fixing seat 1 and the second fixing seat 2, the auxiliary spray pipe 3 can be processed and manufactured separately, which reduces the processing difficulty of the auxiliary spray pipe 3, and makes the later assembly and disassembly simpler, and the maintenance cost is low.
