[0033] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is described in detail, clearly and completely in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.
[0034] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.
[0035] Please see Figure 1 and Figure 2As shown, an embodiment of the present disclosure provides a water distribution mechanism, including a water cup assembly 1 and an inner water pipe 2. The water cup assembly 1 is arranged at the bottom of the inner tank and is a water carrier for washing in the dishwasher. During the washing process of the dishwasher, the washing circulating water flows into the washing pump through the water cup assembly 1, then enters each spray arm through the inner water pipe 2, and finally is sprayed out by the spray arm. In addition, the washing circulating water is also discharged through the water cup assembly 1. The water cup assembly 1 includes a cup body, the cup body is connected to a pipeline, the inner water pipe 2 is connected to the pipeline, and the water in the cup body enters the inner water pipe 2 through the pipeline. In this way, the inner water pipe 2 does not need to be additionally connected to the outer water pipe, which saves the space occupied by the outer water pipe and makes the structure more compact. In addition, the side wall of the inner tank does not need to be additionally provided with a through hole for the inner water pipe 2 to be connected to the outer water pipe, and the strength of the inner tank is also improved. It should be noted that the water cup assembly 1 is connected to a washing pump, and the washing pump draws the water in the cup body into the pipeline, and then enters each spray arm.
[0036] Please also see Figures 4 to 8 As shown, in one embodiment of the present disclosure, a first channel 9 and a second channel are provided in the inner water pipe 2, the first channel 9 is provided with a first interface 3, the first interface 3 is connected to the middle spray arm, the second channel is provided with a second interface 15, the second interface 15 is connected to the top spray arm 4, specifically, the inner water pipe 2 is roughly in a "U"-shaped structure, the inner water pipe 2 is flat, and such a setting can save more space than a cylindrical water pipe, the first end of the inner water pipe 2 is connected to the pipeline, the second interface 15 is provided at the second end of the inner water pipe 2, the second interface 15 is provided above the first interface 3, and the length of the second channel is greater than the length of the first channel 9.
[0037] Furthermore, the second channel includes a first portion 10 and a second portion 11 with different calibers, the second interface 15 is arranged in the second portion 11, the caliber of the second portion 11 is larger than the caliber of the first channel 9, the caliber of the first channel 9 is larger than the caliber of the first portion 10, and the length of the first portion 10 is larger than the length of the first channel 9. Since the water of the water cup assembly 1 enters the first channel 9 and the second channel respectively after entering the inner water pipe 2, and then sprays out from the middle spray arm and the top spray arm 4 respectively, and since the height of the top spray arm 4 is higher than the middle spray arm, the path of the second channel is longer, in order to ensure sufficient water pressure to make the water of the second channel enter the top spray arm 4 to ensure the normal operation of the top spray arm 4, the caliber of the first channel 9 is larger than the caliber of the first portion 10, and the caliber of the second portion 11 is larger than the caliber of the first channel 9. Since water in the first part 10 needs to overcome the effect of gravity and go vertically upward, the caliber of the first part 10 is set to be the smallest to facilitate the enhancement of water pressure, and the second part 11 is almost parallel to the horizontal plane, and the water flow in the second part 11 is relatively smooth, and there is no need to further increase the water pressure. The second part 11 is directly connected to the top spray arm 4, and the caliber of the second part 11 is set larger to facilitate the water flow into the top spray arm 4. In addition, since the second part 11 is directly connected to the top spray arm 4, if the caliber of the second part 11 is set smaller, the water flow in the second part 11 will have a larger water pressure, which will cause an impact on the top spray arm 4 and affect the normal operation of the top spray arm 4. In order to further weaken the impact of the water flow on the top spray arm 4 and the inner water pipe 2, a buffer portion 14 is provided at the connection between the first portion 10 and the second portion 11. The buffer portion 14 is an upward arc structure or an upward slope. Since the caliber of the first portion 10 is smaller, the water flow velocity in the first portion 10 is faster, and the caliber of the second portion 11 is larger than that of the first portion 10. When the water flow just enters the second portion 11 from the first portion 10, the water flow channel will suddenly become larger. In addition, at this time, the water flow just comes out of the first channel 9 at a relatively fast speed, which will cause a huge impact on the connection between the first portion 10 and the second portion 11. The upward arc structure or the upward slope is equivalent to a speed bump, which can effectively slow down the water flow velocity, so as to weaken the adverse effects of the water flow impact on the top spray arm 4 and the inner water pipe 2.It should be noted that the length of the second part 11 is much smaller than that of the first part 10. The first part 10 is arranged in the vertical section of the inner water pipe 2, and the second part 11 is arranged in the section parallel to the horizontal plane of the inner water pipe 2, and the second part 11 is shorter. This is because the water flow needs to pass through a longer path to enter the second interface 15 and be sprayed out by the top spray arm 4. If the second part 11 is arranged in the vertical section of the inner water pipe 2, due to the larger diameter of the second part 11, the flow rate of the water flow in the second part 11 is smaller, and it needs to overcome a larger gravity, and it is more difficult for the water flow to flow to the second interface 15. In addition, when the top spray arm 4 finishes spraying, some water will inevitably remain in the second channel, and most of the remaining water is in the vertical section of the inner water pipe 2. If the second part 11 is arranged in the vertical section of the inner water pipe 2, due to the larger diameter of the second part 11, the total volume of the remaining water is larger, which will cause a waste of water resources.
[0038] For further information, please continue to see Figure 3 and 4 As shown, the second end of the inner water pipe 2 is provided with a first mounting protrusion 12, the first mounting protrusion 12 is connected to a reinforcing plate 13, the reinforcing plate 13 is provided with a first through hole, and the second interface 15 passes through the first through hole and is connected to the top spray arm 4. Since the length of the inner water pipe 2 is relatively long, the top spray arm 4 is suspended at the second end of the inner water pipe 2, which makes the second end of the inner water pipe 2 bear a large downward force. In addition, the caliber of the first part 10 of the second channel is small, which makes the water pressure in the second channel larger. The instantaneous water pressure of the water in the second channel entering the second interface 15 is large, which will also impact the inner water pipe 2. The reinforcing plate 13 is provided to strengthen the structure of the inner water pipe 2 to prevent the inner water pipe 2 from being deformed due to the large force. A plurality of second mounting protrusions 25 are also provided in the middle of the inner water pipe 2, which are used to connect with the inner liner so that the inner water pipe 2 can be better fixed on the inner liner.
[0039] In particular, such as Figure 2 to Figure 4As shown, a hollow section 27 is provided between the second interface 15 and the first interface 3, the hollow section 27 and the first part 10 of the second channel are basically arranged in parallel, the hollow section 27 is arranged on the back of the inner water pipe 2, and the second interface 15 and the first interface 3 are both arranged on the front of the inner water pipe 2. Preferably, the hollow section 27 is provided between the buffer portion 14 and the first channel 9. It should be noted that the lower end of the hollow section 27 is not connected to the upper end of the first channel 9. A first gap 26 is provided between the hollow section 27 and the first part 10 of the second channel, and the width of the first gap 26 is greater than the caliber of the first part 10, and the caliber of the hollow section 27 is greater than the width of the first gap 26. The length of the first part 10 is greater than the length of the first channel 9, and the hollow section 27 is provided above the first channel 9. The total length of the hollow section 27 plus the first channel 9 is substantially equal to the length of the first part 10. Since the length of the first part 10 is greater than the first channel 9, and the caliber of the first part 10 is smaller, the water flow speed is larger, so the force on the entire first part 10 is larger, and the first channel 9 also has a force from the water. The forces on the first channel 9 and the first part 10 are relatively balanced, but the part of the first part 10 that exceeds the length of the first channel 9 (that is, the part where the hollow section 27 is set) has a large difference in the force on the left and right sides of the inner water pipe 2. The hollow section 27 can strengthen the wall thickness at this place, thereby strengthening the structural strength at this place and avoiding deformation. The hollow section 27 can also be set as a solid structure, but the solid structure will consume more raw materials and increase the weight of the entire inner water pipe 2. The inner water pipe 2 in the present disclosure is installed above the water cup assembly 1. If the inner water pipe 2 is too heavy, it will bring inconvenience to the installation and fixation of the inner water pipe 2. A first gap 26 is provided between the hollow section 27 and the first part 10 of the second channel. The provision of the first gap 26 can save raw materials on the one hand and reduce the weight of the inner water pipe 2 on the other hand. Since the width of the first gap 26 is greater than the diameter of the first part 10 and the diameter of the hollow section 27 is greater than the width of the first gap 26, the structural strength of the inner water pipe 2 can be ensured while making the weight of the inner water pipe 2 as light as possible.
[0040] In order to further strengthen the structure of the inner water pipe 2, a reinforcing rib 24 is further provided at the bottom of the hollow section 27, one end of the reinforcing rib 24 is connected to the side wall of the first part 10 of the second channel, and the reinforcing rib 24 is provided at the bottom of the first gap 26. The reinforcing rib 24 is provided at the position where the first channel 9 just ends. Since the water flow of the second channel flows normally at this position, and the first channel 9 ends suddenly, the forces on the left and right sides of the inner water pipe 2 at this position will be momentarily unbalanced, and the inner water pipe 2 is more likely to deform at this position. The reinforcing rib 24 connects the bottom of the hollow section 27 and the side wall of the first part 10 of the second channel, and can effectively transmit the force of the water flow on the second channel to the hollow section 27, so as to balance the force of the inner water pipe 2 at this position and prevent deformation.
