[0001] The utility model relates to the technical field of household appliances, in particular to a water channel system and a dishwasher. Background Art

[0002] Dishwashers are household appliances commonly used in daily life. Existing dishwashers are usually designed with an upper spray arm, a lower spray arm and a small spray arm. When the dishwasher is working, the washing pump transports water with a certain pressure to the upper spray arm, the lower spray arm and the small spray arm through the pipeline. The water is sprayed out from the upper spray arm, the lower spray arm and the small spray arm to rinse the dishes and then returns to the water cup at the bottom of the dishwasher. Then, the washing pump transports the refluxed water to the upper spray arm, the lower spray arm and the small spray arm again to achieve water reuse.

[0003] In the prior art, the upper spray arm, the lower spray arm and the small spray arm are all connected to the water cup by a hose. The water cup is usually arranged at the bottom of the inner barrel of the dishwasher, and the upper spray arm is arranged close to the top of the inner barrel, so that the hose between the upper spray arm and the water cup is longer. In addition, in order to leave more space for the inner barrel to accommodate tableware, the hose needs to extend in line with the side wall of the inner barrel, which makes the hose easy to bend at the corner of the inner barrel, thereby reducing or blocking the water flow cross-sectional area, and increasing the pressure loss, resulting in a lower water flow pressure flowing to the upper spray arm, affecting the washing effect of the tableware.

[0004] Therefore, there is an urgent need for a dishwasher with good washing effect. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] This embodiment provides a water system which is applied to a dishwasher and has a good washing effect.

[0037] like Figures 1 to 5As shown, the water system includes an inner barrel assembly 100 and an upper spray arm water pipe 200. The inner barrel assembly 100 includes a base 110 and an inner barrel 120 disposed on the base 110. The inner barrel 120 has a washing space, and bowl baskets, tableware, etc. can be placed in the washing space. The base 110 is used to provide a storage space for a water diversion valve, a water cup 300, etc.

[0038] The upper spray arm water pipe 200 includes a first pipe section 210 , an adapter 220 , and a second pipe section 230 that are connected in sequence, that is, the first pipe section 210 is connected to the second pipe section 230 through the adapter 220 .

[0039] The adapter 220 is disposed on the base 110, and the adapter 220 includes a first adapter pipe section 221 and a second adapter pipe section 222 that are connected and communicated. The axis of the first adapter pipe section 221 and the axis of the second adapter pipe section 222 are arranged at an obtuse angle, so that the water flow direction in the first adapter pipe section 221 and the water flow direction in the second adapter pipe section 222 are at an obtuse angle, so as to reduce the pressure loss caused by factors such as the water flow turning and hitting the wall. One end of the first pipe section 210 is configured to communicate with the water supply structure of the dishwasher (such as the water cup 300), and the other end of the first pipe section 210 is coaxially connected to the first adapter pipe section 221, so that the water flow direction in the first pipe section 210 is the same as the water flow direction in the first adapter pipe section 221.

[0040] One end of the second pipe segment 230 is coaxially connected to the second transfer pipe segment 222, so that the water flow direction in the second pipe segment 230 is the same as the water flow direction in the second transfer pipe segment 222; the other end of the second pipe segment 230 is configured to be connected to the upper spray arm of the dishwasher, so that the water supply structure, the first pipe segment 210, the first transfer pipe segment 221, the adapter 220, the second transfer pipe segment 222, the second pipe segment 230 and the upper spray arm can form a flow path to provide water with a certain pressure to the upper spray arm.

[0041] The water system provided in this embodiment includes an upper spray arm water pipe 200 including a first pipe section 210, an adapter 220 and a second pipe section 230 which are connected in sequence. The adapter 220 is arranged on the base 110, which prevents the adapter 220 from moving relative to the base 110, thereby fixing the upper spray arm water pipe 200 on the inner barrel assembly 100 and reducing the probability of bending of the upper spray arm water pipe 200. In addition, the axis of the first adapter pipe section 221 of the adapter 220 is arranged at an obtuse angle to the axis of the second adapter pipe section 222. The first adapter pipe section 221 is connected to the first pipe section 210, and the second adapter pipe section 222 is connected to the second pipe section 230, so that the water flow direction in the first pipe section 210 and the water flow direction in the second pipe section 230 are at an obtuse angle. Compared with a right-angle turn, the obtuse-angle turn of the water flow can reduce the pressure loss caused by factors such as water flow turn and wall collision, thereby ensuring the water flow pressure flowing to the upper spray arm, thereby improving the washing effect of the tableware.

[0042] It should be noted that the first pipe section 210 and the second pipe section 230 can be a hose or a hard pipe. Since the adapter 220 is disposed on the base 110 and the first pipe section 210 and the second pipe section 230 are connected via the adapter 220, the first pipe section 210 and the second pipe section 230 will not be bent even if they are hoses, and have high reliability.

[0043] Optionally, the adapter 220 is detachably connected to the base 110 to facilitate cleaning, maintenance and replacement of the adapter 220. For example, the adapter 220 can be connected to the base 110 by means of snap connection, plug connection, bolt connection, etc., which is not limited in this embodiment.

[0044] In some optional embodiments, the upper spray arm water pipe 200 is disposed outside the inner barrel 120, specifically, as Figure 2 As shown, the side wall of the inner barrel 120 is provided with an upper spray arm water inlet 121, and the first pipe section 210, the adapter 220 and the second pipe section 230 are all arranged outside the inner barrel 120, so that the first pipe section 210, the adapter 220 and the second pipe section 230 do not occupy the internal space of the inner barrel 120, so that the inner barrel 120 can have a larger washing space, thereby increasing the capacity of the dishwasher and increasing the space for placing tableware. In addition, the user will not observe the water pipes inside the dishwasher, thereby improving the internal aesthetics of the dishwasher.

[0045] For example, the first pipe section 210 and the second pipe section 230 are arranged near the outer wall of the inner tub 120, and at least part of the second pipe section 230 extends along the corners of the inner tub 120. Since the inner tub 120 and the outer tub of the dishwasher need to be arranged on the base 110, the space between the corners of the inner tub 120 and the outer tub is necessary but cannot be used. Therefore, the second pipe section 230 is arranged at the corners of the inner tub 120 to fully utilize the space, thereby improving the space utilization of the dishwasher. Optionally, at least part of the second pipe section 230 extends along the height direction of the inner tub 120.

[0046] In this embodiment, the second pipe section 230 is communicated with the water inlet 121 of the upper spray arm, and the adapter 220 is disposed on the base 110 . For example, the adapter 220 is detachably connected to the base 110 .

[0047] Alternatively, if Figure 3 As shown, the adapter 220 also includes an adapter seat 223. The first adapter tube section 221 and the second adapter tube section 222 are both connected to the adapter seat 223, and the adapter seat 223 is arranged on the base 110, that is, the adapter seat 223 is detachably connected to the base 110. By providing the adapter seat 223, the flexibility of connecting the adapter 220 to the base 110 is improved, and the difficulty of connecting the adapter 220 to the base 110 is reduced.

[0048] Further optionally, if Figure 4 and Figure 5 As shown, the adapter seat 223 includes a first mounting plate 2231 and a second mounting plate 2232 connected to each other. The first adapter tube section 221 is arranged on the first mounting plate 2231, and the first adapter tube section 221 is arranged on the second mounting plate 2232. In this embodiment, the first mounting plate 2231 and / or the second mounting plate 2232 are connected to the base 110 to have a larger connection area, thereby having a higher connection strength.

[0049] The first mounting plate 2231 and the second mounting plate 2232 are arranged at an angle, and the angle between the first mounting plate 2231 and the second mounting plate 2232 can be a right angle or an obtuse angle. In this embodiment, the angle between the first mounting plate 2231 and the second mounting plate 2232 is an obtuse angle.

[0050] Alternatively, if Figure 5 As shown, a first support plate 2233 is provided on the first mounting plate 2231, and the first transfer tube section 221 is connected to the first support plate 2233 and supported and fixed by the first support plate 2233. By way of example, one or more first support plates 2233 may be provided. When a plurality of first support plates 2233 are provided, a plurality of first support plates 2233 are arranged at intervals in the axial direction of the first transfer tube section 221 to improve the stability and reliability of connecting the first transfer tube section 221. By way of another example, the first support plate 2233 has an arc-shaped opening, and the first transfer tube section 221 is connected to the arc-shaped opening. Optionally, the first support plate 2233 and the first transfer tube section 221 may be integrally formed, bonded or welded, which is not limited in this embodiment.

[0051] Similarly, a second support plate 2234 is provided on the second mounting plate 2232, and the second transfer tube section 222 is connected to the second support plate 2234 and supported and fixed by the second support plate 2234. By way of example, one or more second support plates 2234 may be provided. When there are multiple second support plates 2234, multiple second support plates 2234 are arranged at intervals in the axial direction of the second transfer tube section 222 to improve the stability and reliability of connecting the second transfer tube section 222. By way of another example, the second support plate 2234 has an arc-shaped opening, and the second transfer tube section 222 is connected to the arc-shaped opening. Optionally, the second support plate 2234 and the second transfer tube section 222 may be integrally formed, bonded or welded, which is not limited in this embodiment.

[0052] As mentioned above, please continue to refer to Figure 5 The base 110 is provided with an assembly groove 111, and at least part of the adapter 220 is arranged in the assembly groove 111, which reduces the space required to be occupied by the adapter 220 outside the base 110, and is conducive to the miniaturization of the dishwasher.

[0053] For example, the first mounting plate 2231, at least part of the first adapter tube section 221 and at least part of the second adapter tube section 222 are all arranged in the assembly groove 111, reducing the need for the first mounting plate 2231, the first adapter tube section 221 and the second adapter tube section 222 to occupy additional space outside the base 110.

[0054] In this embodiment, Figure 4 As shown, the second mounting plate 2232 is located outside the assembly groove 111 and connected to the outer wall of the base 110 to improve the connection flexibility between the adapter 220 and the base 110. For example, the second mounting plate 2232 fits the outer wall of the base 110, and since the second mounting plate 2232 is thin, it does not occupy too much space.

[0055] For example, Figure 5 As shown, a screw column 113 is provided on the base 110, which is convenient for fixing the second mounting plate 2232 on the base 110 by bolts. While ensuring the fixed position, the second mounting plate 2232 can also play a role in structural reinforcement of the base 110.

[0056] Alternatively, see Figure 5 The assembly groove 111 is arranged at the corner of the base 110 , that is, the adapter 220 is arranged at the corner of the base 110 , which makes full use of the space at the corner of the base 110 .

[0057] Optionally, the base 110 is provided with a mounting groove 112, and an inner corner of the mounting groove 112 is a right angle. An edge corner of the inner barrel 120 is an arc chamfer, and there is a gap between the arc chamfer and the right-angled inner corner. At least part of the second pipe section 230 and / or at least part of the second transfer pipe section 222 is arranged in the gap to fully utilize the gap between the base 110 and the inner barrel 120, and on the basis of the existing assembly of the base 110 and the inner barrel 120, no additional pipeline installation space is required.

[0058] In some optional embodiments, such as Figure 2 As shown, the upper spray arm water pipe 200 also includes a third pipe section 240. The third pipe section 240 is connected to the end of the second pipe section 230 away from the adapter 220, and the end of the third pipe section 240 away from the second pipe section 230 is connected to the upper spray arm of the dishwasher, that is, the second pipe section 230 is connected to the upper spray arm water inlet 121 through the third pipe section 240. By providing the third pipe section 240, the flexibility of the setting position of the upper spray arm water inlet 121 is improved, so that a shorter pipeline can be provided between the upper spray arm and the upper spray arm water inlet 121, further increasing the washing space of the inner barrel 120.

[0059] Optionally, the axis of the third pipe section 240 is set at an obtuse angle to the axis of the second pipe section 230, which reduces the pressure loss caused by factors such as turning and hitting the wall when the water flows from the second pipe section 230 to the third pipe section 240, which is conducive to improving the washing effect. The connection between the second pipe section 230 and the third pipe section 240 is arc-shaped, which further reduces the pressure loss.

[0060] For example, the second pipe section 230 and the third pipe section 240 are an integrated structure, for example, the second pipe section 230 and the third pipe section 240 are a hose to reduce the number of joints. Of course, it is understandable that the second pipe section 230 and the third pipe section 240 can also be two pipes, which are connected and communicated through a joint.

[0061] In this embodiment, the first transfer pipe section 221 is sealed and connected to the first pipe section 210 to prevent water leakage. Figure 5 A sealing ring 224 is provided at the connection between the first transfer tube section 221 and the first tube section 210. In this embodiment, the sealing ring 224 is sleeved on the first transfer tube section 221.

[0062] Similarly, the second transfer pipe section 222 is sealed and connected to the second pipe section 230 to prevent water leakage. For example, a sealing ring 224 is provided at the connection between the second transfer pipe section 222 and the second pipe section 230. In this embodiment, the sealing ring 224 is sleeved on the second transfer pipe section.

[0063] The water system provided in this embodiment adopts a segmented water system (i.e., a first pipe segment 210 and a second pipe segment 230) to supply water to the upper spray arm. Compared with a method of directly supplying water with a hose, it has higher water pressure stability and avoids the random folding effect caused by the hose bypassing the base 110, resulting in a reduction in or blockage of the water flow area.

[0064] This embodiment also provides a dishwasher, which includes the above-mentioned water channel system and has the technical effects that can be achieved by the above-mentioned water channel system.

[0065] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
