[0002] The dishwasher has a water cup and a washing pump, which are connected to the water cup by a rubber tube to transmit water. The washing pump generates noise when in operation. In order to prevent the noise from being transmitted to the water cup and causing the whole dishwasher to vibrate, the rubber tube is designed to be longer, so as to absorb the vibration generated by the washing pump, prevent the vibration from being transmitted to the water cup, and reduce the occurrence of noise. However, an overly long rubber tube will take up too much space, reduce space utilization, and is not convenient for the miniaturization design of the dishwasher. In addition, an overly long rubber tube will increase water resistance and reduce the efficiency of water flow. Summary of the invention

[0004] To achieve the above object, the present application discloses a connecting pipe suitable for elastic deformation, the connecting pipe comprising:

[0005] A first flow section, suitable for connecting to a first joint of the pump body;

[0006] A second flow section, adapted to be connected to a second connector; and

[0007] The third flow segment is arranged between the first flow segment and the second flow segment. The third flow segment is raised relative to the first flow segment and the second flow segment and forms an open concave cavity.

[0008] In some embodiments of the present application, a flow channel is arranged around the connecting pipe, the third flow section is arranged to be raised away from the flow channel, and the concave cavity is connected to the flow channel.

[0009] In some embodiments of the present application, the third flow segment is inclined toward the first flow segment or the second flow segment.

[0010] In some embodiments of the present application, along the radial direction of the connecting pipe, the third flow section at least partially overlaps with the first joint or the second joint.

[0011] In some embodiments of the present application, the direction from one of the first flow segment and the second flow segment to the other is the flow direction of the fluid, and the third flow segment is inclined toward the one.

[0012] In some embodiments of the present application, the first flow segment is sleeved on the first joint; and / or the second flow segment is sleeved on the second joint.

[0013] In some embodiments of the present application, the connecting tube is a rubber tube.

[0015] In some embodiments of the present application, the dishwasher includes a pump body and a water cup, the pump body includes a first joint provided with a first inlet, the water cup includes a second joint provided with a second outlet, and the connecting pipe is connected to the first inlet and the second outlet.

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0044] The present application proposes a connecting pipe 3000, which is suitable for transmitting fluid. Hereinafter, the connecting pipe 3000 is combined with a dishwasher for detailed description, and the fluid is described by taking water as an example. It can be understood that the connecting pipe 3000 is not limited to being applied to dishwashers, but can also be applied to other types of equipment that need to realize fluid transmission, and the fluid can be liquid or gas.

[0045] Combination Figures 4 to 7 As shown, in some embodiments of the present application, the connecting pipe 3000 includes a first flow segment 3100, a third flow segment 3300 and a second flow segment 3200. The third flow segment 3300 of the connecting pipe 3000 is designed to be raised and form a concave cavity 3310. When the vibration generated by the pump body 1000 during operation is transmitted to the connecting pipe 3000, the third flow segment 3300 can absorb the vibration to a certain extent, thereby suppressing the transmission of the vibration, playing a shock absorbing role, and reducing the generation of noise. It is precisely because of the setting of the third flow segment 3300 that the length of the connecting pipe 3000 can be shortened, the space occupied can be reduced, the space utilization rate can be improved, the resistance to the fluid can be reduced, and the fluid operation efficiency of the equipment can be improved.

[0046] Specifically, the dishwasher includes an inner tank (not shown in the figure), a water cup 2000, a pump body 1000 and a spray arm (not shown in the figure). The water cup 2000 is arranged at the bottom of the inner tank. When the dishwasher is working, water is passed into the inner tank, and the water flows into the water cup 2000 under the action of gravity. The pump body 1000 is a component that provides power for fluid transmission. The pump body 1000 and the water cup 2000 are connected to each other and are used to suck the water in the water cup 2000 and transport it to the spray arm, so that the spray arm sprays out water to wash the dishes.

[0047] When the pump body 1000 is sucking water from the water cup 2000, the motor of the pump body 1000 needs to rotate at high speed, thus generating certain vibrations. In order to prevent the vibrations of the pump body 1000 from being transmitted to the water cup 2000 and then causing the entire dishwasher to vibrate, the pump body 1000 and the water cup 2000 need to be connected through the connecting pipe 3000.

[0048] The connecting tube 3000 can achieve elastic deformation, so that the connecting tube 3000 constitutes a flexible tube. It is understandable that the elastic deformation of the connecting tube 3000 can be based on the characteristics of its material. For example, the connecting tube 3000 is a rubber tube, which is mainly made of rubber, or a silicone tube, which is mainly made of silicone. Of course, in other embodiments, it can also be made of other materials, as long as the connecting tube 3000 has a certain elasticity.

[0049] In order to realize the connection between the connecting pipe 3000, the pump body 1000 and the water cup 2000, Figures 1 to 3 As shown, the pump body 1000 includes a first joint 1100, and the water cup 2000 includes a second joint 2100. It can be understood that the first joint 1100 and the second joint 2100 provide support points for connecting with the connecting pipe 3000, and realize physical contact with the connecting pipe 3000, so that water can be transmitted under the action of the pump body 1000. For example, the first flow segment 3100 is sleeved on the first joint 1100. Since the connecting pipe 3000 can be elastically deformed, when the first flow segment 3100 is sleeved on the first joint 1100, it can tightly press the first joint 1100 along the circumference of the first joint 1100, increase the contact area between the first joint 1100 and the first joint 1100, and improve the sealing effect. The second flow segment 3200 can also be sleeved on the second joint 2100, similar to the sleeve of the first flow segment 3100 on the first joint 1100, and no further description will be given. For non-dishwasher products, the second connector 2100 needs to be disposed on a corresponding component, so that the corresponding component of the second connector 2100, the connecting pipe 3000 and the pump body 1000 form a flow path.

[0050] The first flow segment 3100 of the connecting pipe 3000 is connected to the first joint 1100 of the pump body 1000, and the second flow segment 3200 of the connecting pipe 3000 is connected to the second joint 2100 of the water cup 2000, and the third flow segment 3300 is arranged between the second flow segment 3200 and the first flow segment 3100, one end of the third flow segment 3300 is connected to the first flow segment 3100, and the other end of the third flow segment 3300 is connected to the second flow segment 3200, and the third flow segment 3300 is raised relative to the second flow segment 3200 and the first flow segment 3100, and a concave cavity 3310 is formed, and the concave cavity 3310 is in an open state, so-called raised The third flow segment 3300 is provided so as to prevent the vibration from being transmitted to the second flow segment 3200, thereby preventing the vibration from being transmitted to the water cup 2000. In this way, the overall vibration of the dishwasher is suppressed and the noise is reduced.

[0051] In addition, it is through the provision of the third flow section 3300 that the vibration transmitted from the pump body 1000 can be absorbed. Therefore, under the premise of ensuring the noise reduction effect, the connecting pipe 3000 no longer needs to be designed to be too long. That is to say, by providing the third flow section 3300, the connecting pipe 3000 can be shortened as much as possible while ensuring a certain noise reduction and vibration suppression effect. The connecting pipe 3000 with a shorter length can reduce the resistance of water flow transmission, improve the water flow operation efficiency, and reduce the power requirements for the pump body 1000.

[0052] Generally speaking, the pump body 1000 needs to be installed in the base of the dishwasher. If the length of the connecting pipe 3000 is too long, it will take up too much space, which is not convenient for the arrangement of various components. The connecting pipe 3000 may also need to be bent to achieve the connection between the water cup 2000 and the pump body 1000. The bent connecting pipe 3000 will increase the resistance to the water flow. Based on the setting of the third flow section 3300, the connecting pipe 3000 is shortened as much as possible, thereby reducing the space occupied by the connecting pipe 3000, making it more convenient to arrange the remaining components, and making the base of the dishwasher more compact. In addition, the connecting pipe 3000 with a shorter length can avoid bending, thereby reducing the resistance to the water flow.

[0053] Combination Figures 4 to 7 As shown, in some embodiments of the present application, the connecting pipe 3000 is configured with a flow channel 3400, and the third flow segment 3300 needs to be raised away from the flow channel 3400, so that the resistance to water flow transmission will not be increased due to the raised setting of the third flow segment 3300.

[0054] Specifically, the connecting pipe 3000 is a hollow structure pipe, and thus a flow channel 3400 is arranged around it. When the pump body 1000 is running, the pump body 1000 draws water in the water cup 2000, and the water in the water cup 2000 flows out from the second joint 2100 and enters the flow channel 3400 of the connecting pipe 3000, and then enters the pump body 1000 through the first joint 1100. The third flow segment 3300 is arranged away from the flow channel 3400, that is, the third flow segment 3300 protrudes relative to the outer surface of the connecting pipe 3000 to form a bulge-shaped structure. When water is transmitted in the flow channel 3400 of the connecting pipe 3000, it will not be blocked by the third flow segment 3300, so as to avoid the bulge setting of the third flow segment 3300 to increase the resistance to the water flow.

[0055] When the third flow segment 3300 rises away from the flow channel 3400, it continues to combine Figures 4 to 7 As shown, in some embodiments of the present application, the third flow segment 3300 is tilted toward the second flow segment 3200 or the first flow segment 3100, which can further enhance the ability of the third flow segment 3300 to absorb vibrations and further reduce the occurrence of noise.

[0056] Specifically, the third flow segment 3300 is tilted toward the second flow segment 3200 as an example for explanation. Since the positions of the water cup 2000 and the pump body 1000 are relatively fixed, it is difficult for the connecting pipe 3000 to undergo elastic deformation along the axial direction of the connecting pipe 3000. When the third flow segment 3300 is tilted, the concave cavity 3310 can be compressed and expanded along the radial direction of the connecting pipe 3000. In other words, the third flow segment 3300 can undergo elastic deformation in the radial direction of the connecting pipe 3000. Compared with the axial direction of the connecting pipe 3000, the radial space of the connecting pipe 3000 is more sufficient. Therefore, with such a configuration, the third flow segment 3300 can ensure deformation in the radial direction of the connecting pipe 3000, thereby enhancing the absorption of vibration. It can be understood that when the third flow segment 3300 is tilted toward the first flow segment 3100, it also has similar technical effects, which will not be repeated here.

[0057] Combination Figure 3 As shown, in some embodiments of the present application, when the third flow segment 3300 is tilted, the third flow segment 3300 at least partially overlaps with the first joint 1100 along the radial direction of the connecting pipe 3000, or the third flow segment 3300 at least partially overlaps with the second joint 2100 along the radial direction of the connecting pipe 3000, thereby further shortening the length of the connecting pipe 3000 and further reducing the space occupied.

[0058] Specifically, when the third flow segment 3300 is tilted toward the first flow segment 3100, along the radial direction of the connecting pipe 3000, the third flow segment 3300 and the first flow segment 3100 also overlap at least partially, and since the third flow segment 3300 and the first joint 1100 need to overlap at least partially, the first flow segment 3100 basically overlaps with the first joint 1100, that is, when the water flows out of the water cup 2000 through the second joint 2100, the first flow segment 3100 can not generate resistance to the water flow, thereby further improving the water flow transmission efficiency. In addition, since the first flow segment 3100 basically overlaps with the first joint 1100, the distance between the first joint 1100 and the second joint 2100 is less than the sum of the lengths of the third flow segment 3300 and the second flow segment 3200, further reducing the space occupied. In addition, the first flow segment 3100 basically overlaps with the first joint 1100, and the first joint 1100 supports the first flow segment 3100. Since the first flow segment 3100 and the third flow segment 3300 are at least partially overlapped, aging, fracture and water leakage at the intersection of the third flow segment 3300 and the first flow segment 3100 due to vibration can be avoided.

[0059] Optionally, when the third flow segment 3300 is tilted toward the second flow segment 3200, it is also along the radial direction of the connecting pipe 3000, and the third flow segment 3300 and the second flow segment 3200 also overlap at least partially. Since the third flow segment 3300 and the second joint 2100 need to overlap at least partially, the third flow segment 3300 basically overlaps with the second joint 2100, that is, when the water flows out of the water cup 2000 through the second joint 2100, the second flow segment 3200 can not generate resistance to the water flow, thereby further improving the water flow delivery efficiency. In addition, since the second flow segment 3200 basically overlaps with the second joint 2100, the distance between the first joint 1100 and the second joint 2100 is less than the sum of the lengths of the third flow segment 3300 and the first flow segment 3100, further reducing the space occupied.

[0060] Combination Figure 3 As shown, in some embodiments of the present application, the direction of one of the second flow segment 3200 and the first flow segment 3100 toward the other is defined as the flow direction of the fluid, and the third flow segment 3300 is inclined toward the aforementioned one, so that the resistance of the fluid can be further reduced.

[0061] Specifically, one of the aforementioned is the second flow segment 3200, the other is the first flow segment 3100, and the third flow segment 3300 is inclined toward the second joint 2100, and the water flows out from the water cup 2000 through the second joint 2100, and flows into the pump body 1000 through the first joint 1100 ( Figure 3The arrow in the flow channel 3400 is the direction of fluid flow. When the water flows through the flow channel 3400 formed by the connecting pipe 3000, when the water flows over the portion between the second flow segment 3200 and the third flow segment 3300, the water flow can continue to pass through the concave cavity 3310 under the action of inertia, thereby reducing the resistance of water flow transmission. If the third flow segment 3300 is inclined toward the other of the aforementioned, then when the water flows over the portion between the second flow segment 3200 and the third flow segment 3300, a part of the water flow will directly rush into the concave cavity 3310, which will undoubtedly increase the resistance of water flow transmission.

[0062] As described above, the pump body 1000 is connected to the water cup 2000 through the connecting pipe 3000 to suck the water in the water cup 2000. In other embodiments, the spray arm can be connected to the water cup 2000 through the spray arm pipeline, and the pump body 1000 can also be connected to the water cup 2000 through the connecting pipe 3000 and then connected to the spray arm pipeline to transport the water sucked from the water cup 2000 to the spray arm (described in detail below). In this case, water flows out from the first joint 1100 of the pump body 1000 and is transported to the second joint 2100 through the connecting pipe 3000. At this time, the third section is inclined toward the first flow section 3100, that is, it is inclined toward the first joint 1100.

[0063] The second aspect of the present application further discloses a dishwasher, which includes the connecting pipe 3000 of the above embodiment. It can be understood that the connecting pipe 3000 of the dishwasher of this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0064] The pump body 1000 is connected to the water cup 2000 through the connecting pipe 3000. When the pump body 1000 is working, the water can flow from the water cup 2000 toward the pump body 1000, or the water can flow from the pump body 1000 toward the water cup 2000. The above mainly describes the flow of water from the water cup 2000 toward the pump body 1000, which will be further described below.

[0065] For the first case, combined with Figure 3As shown, the first joint 1100 of the pump body 1000 is provided with a first inlet 1110, and the first joint 1100 provided with the first inlet 1110 is defined as the water inlet first joint 1100, and the second joint 2100 of the water cup 2000 is provided with a second outlet 2110, and the second joint 2100 provided with the second outlet 2110 is defined as the water outlet second joint 2100. The water in the inner tank of the dishwasher will flow to the water cup 2000 under the action of gravity, and the pump body 1000 will suck the water in the water cup 2000 when working, and the water will flow out from the second outlet 2110 of the water outlet second joint 2100, and then enter the pump body 1000 through the connecting pipe 3000 and the first inlet 1110 of the water inlet first joint 1100, and then be transported to the spray arm under the suction action of the pump body 1000.

[0066] For the second case, the first joint of the pump body 1000 is provided with a first outlet (not shown in the figure), and the first joint provided with the first outlet is defined as the first water outlet joint, the second joint of the water cup 2000 is provided with a second inlet (not shown in the figure), and the second joint provided with the second inlet is defined as the second water inlet joint, and the spray arm of the dishwasher is connected to the second water inlet joint through the spray arm pipeline to communicate with the second inlet. The pump body 1000 draws water from the water cup 2000 and discharges it from the first outlet of the first water outlet joint, and then flows into the spray arm pipeline through the connecting pipe 3000 and then through the second inlet of the second water inlet joint, and then transported to the spray arm.

[0067] Combination Figure 3 As shown, in some embodiments of the present application, the diameter of the second outlet 2110 is smaller than the diameter of the first inlet 1110. Since the water needs to flow out from the second outlet 2110 and flow in through the first inlet 1110, and since the connecting pipe 3000 can be designed to be shorter, the water flowing out of the second outlet 2110 is easy to collide with the periphery of the first inlet 1110 to form water resistance, and the diameter of the second outlet 2110 is designed to be smaller, so that the water flows more smoothly into the first inlet 1110. The same is true for the first outlet and the second inlet. The diameter of the second inlet is designed to be larger to reduce water resistance, which will not be repeated here.

[0068] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
