[0035] This embodiment provides an external water system, which is applied to a dishwasher, improves the internal space utilization of the dishwasher, and reduces the probability of discoloration and damage of the pipeline.
[0036] like Figures 1 to 6 As shown, the external water system includes an inner tub 100 and an upper spray arm water pipe 300. The inner tub 100 is provided with an upper spray arm water inlet 110, through which water can be supplied to the upper spray arm 800 of the dishwasher.
[0037] The upper spray arm water pipe 300 is arranged outside the inner tub 100. The upper spray arm water pipe 300 includes a first pipe section 310 and a second pipe section 320 that are connected and communicated. One end of the first pipe section 310 away from the second pipe section 320 is communicated with the water supply structure of the dishwasher, and the water supply structure is used to supply water to the first pipe section 310. At least part of the second pipe section 320 extends along the corner 120 of the inner tub 100 and is communicated with the upper spray arm water inlet 110 to provide water to the upper spray arm water inlet 110. The external water system provided in this embodiment has an inner barrel 100 provided with an upper spray arm water inlet 110, and the upper spray arm water inlet 110 is connected to the water supply structure through an upper spray arm water pipe 300. The upper spray arm water pipe 300 includes a first pipe section 310 and a second pipe section 320 that are connected. The end of the first pipe section 310 that is away from the second pipe section 320 is connected to the water supply structure, and at least a portion of the second pipe section 320 extends along the corner 120 of the inner barrel 100 and is connected to the upper spray arm water inlet 110. Since the corner 120 of the inner barrel 100 is usually a space that cannot be used by the dishwasher, at least a portion of the second pipe section 320 is set to extend along the corner 120, so that this part of the space is fully utilized without occupying the space inside the inner barrel 100, thereby increasing the space for placing tableware and setting a bowl basket in the inner barrel 100, and improving the internal space utilization rate of the dishwasher.
[0038] Moreover, in the present embodiment, the upper spray arm water pipe 300 is arranged outside the inner barrel 100, so that the outer wall of the upper spray arm water pipe 300 does not directly contact water and liquid mixed with detergent, thereby reducing the probability of discoloration, oxidation, and damage of the upper spray arm water pipe 300, and extending the service life of the external water system and the dishwasher.
[0039] In addition, the user will not observe the upper spray arm water pipe 300 inside the dishwasher, thereby improving the internal aesthetics of the dishwasher.
[0040] In some optional embodiments, the bottom of the inner barrel 100 is installed in the base of the dishwasher, and there is a gap between the corner 120 of the inner barrel 100 and the inner wall of the base, and at least part of the second pipe section 320 is arranged in the gap to make full use of the space that cannot be used by the dishwasher.
[0041] In this embodiment, the specific structure of the water supply structure is not limited in this embodiment, as long as it can realize water supply to the first pipe section 310. For example, the water supply structure can be a water distribution device 200 of a dishwasher, and the water distribution device 200 is used to receive the water in the inner barrel 100 so that the water in the inner barrel 100 can flow into the water distribution device 200 for recycling. The water distribution device 200 is also used to communicate with an external water source so that the external water source can provide water to the water distribution device 200. Figure 6As shown, the water distribution device 200 is provided with a plurality of water distribution holes 201, and the first pipe section 310 is connected to one of the water distribution holes 201. It should be noted that the water distribution device 200 can be a structure in the prior art, such as a water cup in the prior art, and this embodiment does not limit this.
[0042] Optionally, the inner barrel 100 has a height direction, and at least part of the second pipe section 320 extends along the height direction of the inner barrel 100 , which can fully utilize the corners 120 of the inner barrel 100 on the one hand, and can also adapt to the position of the upper spray arm 800 in the inner barrel 100 on the other hand.
[0043] In some optional embodiments, the angle between the axis direction of the first pipe section 310 and the axis direction of the second pipe section 320 is greater than 90°, that is, the first pipe section 310 and the second pipe section 320 are arranged at an obtuse angle to reduce the pressure loss caused by the water flow diversion and further improve the cleaning rate. For example, the angle between the axis direction of the first pipe section 310 and the axis direction of the second pipe section 320 is 95°, 100°, 130°, 170°, etc.
[0044] As described above, the inner barrel 100 can be installed on the base 700 of the dishwasher, the first pipe section 310 and the second pipe section 320 can be connected through the water pipe adapter 350, and the water pipe adapter 350 can be fixed on the base 700.
[0045] Optionally, the angle between the axis direction of the first pipe section 310 and the axis direction of the water diversion hole 201 connected thereto is greater than 90°, that is, the first pipe section 310 and the water diversion hole 201 form an obtuse angle along the water flow direction to minimize the pressure loss caused by the water flow diversion and further improve the cleaning rate. For example, the angle between the axis direction of the first pipe section 310 and the axis direction of the water diversion hole 201 connected thereto is 100°, 130°, 170°, etc.
[0046] In this embodiment, Figure 2 As shown, the inner barrel 100 has a front portion 140 and a rear portion 150 in the width direction thereof. The front portion 140 of the inner barrel 100 is provided with an opening 141, through which tableware can be placed in the inner barrel 100, and the second pipe section 320 is arranged at the corner 120 of the rear portion 150 of the inner barrel 100 to fully utilize the corner space behind the inner barrel 100. In addition, the opening 141 is installed with a door panel, and the second pipe section 320 is arranged at the corner 120 of the rear portion 150 of the inner barrel 100 to avoid interference between the second pipe section 320 and the door panel, so as to facilitate the opening and closing of the door panel.
[0047] In some optional embodiments, the upper spray arm water inlet 110 is disposed at a corner 120 of the inner barrel 100 , and one end of the second pipe section 320 away from the first pipe section 310 is directly connected to and communicated with the upper spray arm water inlet 110 .
[0048] In some other optional embodiments, such as Figure 4 and Figure 5 As shown, the upper spray arm water pipe 300 also includes a third pipe section 330. The third pipe section 330 is connected to one end of the second pipe section 320 away from the first pipe section 310. The third pipe section 330 is connected to the upper spray arm water inlet 110, that is, the third pipe section 330 is connected to the second pipe section 320 and the upper spray arm water inlet 110. The extension direction of the third pipe section 330 intersects with the extension direction of the second pipe section 320, so as to be suitable for the case where the upper spray arm water inlet 110 is not arranged at the corner 120 of the inner barrel 100. The social group of the third pipe section 330 increases the flexibility and application range of the external waterway system.
[0049] As described above, in this embodiment, the angle between the axis direction of the second pipe section 320 and the axis direction of the third pipe section 330 is greater than 90°, that is, the second pipe section 320 and the third pipe section 330 are arranged at an obtuse angle to reduce the pressure loss caused by the water flow diversion and improve the cleaning rate. For example, the angle between the axis direction of the second pipe section 320 and the axis direction of the third pipe section 330 is 100°, 130°, 170°, etc.
[0050] In some optional embodiments, the connection between the second pipe section 320 and the third pipe section 330 is arc-shaped, so as to guide the water flow and further reduce the pressure loss caused by the water flow diversion.
[0051] For example, the second pipe section 320 and the third pipe section 330 are an integrated structure, for example, the second pipe section 320 and the third pipe section 330 are a hose to reduce the number of joints. Of course, it is understandable that the second pipe section 320 and the third pipe section 330 can also be two pipes, which are connected and communicated through a joint.
[0052] Alternatively, if Figure 3 As shown, the first pipe section 310 is disposed near the bottom wall of the inner barrel 100. For example, the bottom wall of the inner barrel 100 is polygonal, and the first pipe section 310 extends along a diagonal direction of the bottom wall, so that the length of the first pipe section 310 can be shorter, so as to reduce the material used for the first pipe section 310, thereby reducing the flow resistance of the first pipe section 310.
[0053] Alternatively, if Figure 6 As shown, a first connector 500 is provided at the water inlet 110 of the upper spray arm of the inner barrel 100, and the third pipe section 330 is sealedly connected to the first connector 500 to ensure the sealing of the connection position.
[0054] In this embodiment, Figure 3As shown, the external water system also includes a small spray arm water pipe 400, which is arranged outside the inner barrel 100. That is, the small spray arm water pipe 400 does not occupy the internal space of the inner barrel 100, further improving the space utilization rate of the dishwasher so that the space of the inner barrel 100 can be fully released.
[0055] In this embodiment, Figure 6 As shown, the inner barrel 100 is also provided with a small spray arm water inlet 130. Among them, the first pipe section 310 is communicated with one of the water diversion holes 201, one end of the small spray arm water pipe 400 is communicated with the small spray arm water inlet 130, so that water is supplied to the small spray arm water inlet 130 through the small spray arm water pipe 400, and the other end of the small spray arm water pipe 400 is communicated with another water diversion hole 201, so that the water in the water diversion device 200 can enter the small spray arm water pipe 400. It should be noted that the small spray arm water inlet 130 is connected and communicated with the small spray arm 900, so that water can enter the small spray arm 900 from the small spray arm water inlet 130 and be sprayed out through the small spray arm 900.
[0056] In some optional embodiments, the small spray arm water inlet 130 is arranged on the bottom wall of the inner barrel 100. Since the water distribution device 200 is arranged at the bottom of the inner barrel 100, setting the small spray arm water inlet 130 on the bottom wall of the inner barrel 100 can shorten the length of the small spray arm water pipe 400, reduce consumables and reduce pressure loss.
[0057] For example, Figure 3 As shown, a second connector 600 is provided at the water inlet 130 of the small spray arm, and the small spray arm water pipe 400 is sealedly connected to the second connector 600 to ensure the sealing of the connection position.
[0058] Alternatively, if Figure 2 As shown, the bottom wall of the inner barrel 100 is provided with a lower spray arm water inlet 160, and the water distribution device 200 is provided with a plurality of water distribution holes 201, the first pipe section 310 is connected to one water distribution hole 201, and the lower spray arm water inlet 160 is connected to another water distribution hole 201, so that the water distribution device 200 can supply water to the lower spray arm water inlet 160. In this embodiment, the water distribution device 200 includes three water distribution holes 201, wherein the first water distribution hole 201 is connected to the first pipe section 310, the second water distribution hole 201 is connected to the small spray arm water pipe 400, and the third water distribution hole 201 is connected to the lower spray arm water inlet 160, so that the upper spray arm 800, the lower spray arm and the small spray arm 900 are all supplied with water separately without affecting each other. In this embodiment, the lower spray arm water inlet 160 can be connected to another water distribution hole 201 through a pipeline, a joint and other structures, which is not limited in this embodiment.
[0059] The present embodiment further provides a dishwasher, comprising the above-mentioned external water system. The dishwasher provided by the present embodiment has a high space utilization rate and a long service life.
[0060] Alternatively, if Figure 2 As shown, the dishwasher further includes a base 700. The bottom of the inner tub 100 is installed in the base 700, and there is a gap (not shown) between the corner 120 of the inner tub 100 and the side wall of the base 700. At least part of the second pipe section 320 is arranged in the gap, so that the gap between the base 700 and the inner tub 100 can be fully utilized.
[0061] Further optionally, the inner barrel 100 is square, and one corner 120 of the inner barrel 100 is an arc chamfer, the base 700 is provided with a square mounting groove, and one inner corner of the mounting groove is a right angle. An arc chamfer cooperates with an inner corner of the mounting groove to form a gap, and at least part of the second pipe section 320 is located in the gap.
[0062] It should be noted that, due to the existence of the arc chamfer, the arc chamfer will not directly contact the inner corner of the corresponding installation groove, but will inevitably form a gap with a cross-section similar to a triangle for accommodating the second pipe section 320.
[0063] Optionally, the first pipe section 310 is disposed between the bottom wall of the inner tub 100 and the base 700 , so that the first pipe section 310 is relatively concealed and does not affect the appearance of the dishwasher.
[0064] 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.
